Implementation and outcomes of a dementia-friendly training program in five hospitals

Background: Hospitalized patients living with dementia (PLWD) age 65+ generally experience poor outcomes. This study's purpose was to implement dementia-friendly training with staff, track patient outcomes, and implement sustainable system changes.Methods: We conducted a prospective study in five hospitals. The hospitals adopted HealthCare Interactive's CARES® Dementia 5-Step Method for Hospitals Online Training and Certification Program . After on-line modules completion, a didactic session was offered, and a retrospective pre/post survey was completed. Patient falls, length of stay, and readmission rates were collected.Results: 1,836 (41 %) staff completed the training. Positive changes in staff ratings from pre- to post- intervention were observed. Number of falls and readmissions did not change. The average number of stays per patient decreased by .24 (p=0.01). Hospitals made system changes including innovative identification for PLWD.Conclusions: Dementia-friendly hospital training is effective in improving staff recognition of the symptoms and needs of PLWD, and responding appropriately.

Effets du programme d'aide au retour à domicile (PRADO-IC) sur le parcours de soins à un an d'une population de patients insuffisants cardiaques

IntroductionCongestive heart failure (HF) is associated with prolonged and recurrent hospitalizations; the prognosis remains poor a better follow up might be beneficial. PRADO-IC program is provided in order to improve the transition of care. Aim of the studyTo evaluate PRADO-IC program in term of healthcare consumption and prognosis in a cohort of patients hospitalized for decompensated HF, using the insight of the national data base SNDS (Système National de Données de Santé). MethodsFrom September 2016 to September 2018, all patients hospitalized for heart failure at Saint-Joseph Hospital were included in an observational study. The inclusion in the PRADO-IC program was at physician's discretion. Two groups were compared according to the inclusion in PRADO-IC (P group) or not (control group (C)). The primary endpoints were the comparison of one-year mortality and heart failure readmission rate between the two groups. The secondary end points were time to the first contact with a general practitioner (GP), a cardiologist, CHF drugs prescription, and others follow up data. ResultsSix hundred and fifteen patients were included, 254 in the P group and 361 in the C group. Patients in the P cohort presented more frequently severity criteria (age, weight, BNP level, arrhythmia, anemia, renal failure). Mortality at one year (n = 47; 18.5% P group vs. n = 65; 16.2% C group, p = 0.87) did not differ in both groups. There was no significant difference in one-year re-hospitalization rate for HF (n = 93, 36.6% in P group vs. n = 133, 26.8% in C group, p = 0.95). Time to the first contact with the GP was shorter in P group (8.00 vs. 18.50 days, p < 0.0001). Time to first hospitalization (69.0 vs. 37.0 days, p = 0.028) and the length of hospitalization (6.0 vs. 4.0 days, p = 0.045) were longer in P group. There was no difference for HF drugs prescription rate between the two groups. ConclusionOur study shows that the PRADO-IC program concerned more severe patients. Despite this, the one-year mortality and the HF readmission rates are similar between the two groups. The follow up is improved in P group.

Rates and Risk Factors for 30-Day Morbidity After One-Stage Vertical Banded Gastroplasty Conversions: A Retrospective Analysis.

Background: The vertical banded gastroplasty (VBG) is a historic restrictive bariatric operation often requiring further surgery. In this investigation utilizing the 2021 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) national dataset, we aim to better define the outcomes of VBG conversions.Methods: We queried the 2021 MBSAQIP dataset for patients who underwent a conversion from a VBG to Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Demographics, comorbidities, laboratory values, and additional patient factors were examined. Rates of key consequential outcome measures 30-day readmission, reoperation, reintervention, mortality, and a composite endpoint (at least 1 of the 4) were further calculated.Results: We identified 231 patients who underwent conversion from VBG to SG (n = 23), RYGB (n = 208), or other anatomy (n = 6), of which 93% of patients were female, and 22% of non-white race. The median age was 56years and body-mass index (BMI) was 43kg/m2. The most common surgical indications included weight considerations (48%), reflux (25%), anatomic causes (eg, stricture, fistula, and ulcer; 10%), and dysphagia (6.5%). Thirty-day morbidity rates included reoperation (7.8%), readmission (9.1%), reintervention (4.3%), mortality (.4%), and the composite endpoint (15%). Upon bivariate analysis, we did not identify any specific risk factor for the 30-day composite endpoint.Discussion: One-stage VBG conversions to traditional bariatric anatomy are beset with higher 30-day morbidity relative to primary procedures. Additional MBSAQIP data will be required for aggregation, to better characterize the risk factors inherent in these operations.

Enhanced recovery after surgery for hip and knee arthroplasty: A systematic review and meta-analysis on randomized control trials

ObjectivesThis review aimed to compare the efficacy and safety of enhanced recovery after surgery (ERAS) versus traditional care in patients who underwent total hip arthroplasty (THA) and total knee arthroplasty (TKA). MethodsAll randomized controlled trials (RCTs) were acquired via a comprehensive search of multiple databases. A meta-analysis was performed using Cochrane Collaboration's RevMan 5.4 software to calculate effect sizes. ResultsThis meta-analysis included 850 patients in the ERAS group and 845 patients in the control group (patients who received traditional care). The outcomes suggested no significant difference in operative time, intraoperative blood loss, visual analogue scale, 30-day readmission rate, and mortality rate between the two groups. However, the ERAS group was associated with a significant decrease in transfusion rate, hospital length of stay, and postoperative complications. Moreover, the ERAS group had higher Hospital for Special Surgery scores and satisfaction rates. ConclusionsPatients who underwent THA and TKA would benefit more from ERAS than traditional care.

Effects of the Strong Hearts program at two years post program completion.

This is a follow-up to the original published article, Effects of the Strong Hearts Program after a Major Cardiovascular Event in Patients with Cardiovascular Disease. This study evaluated the long-term efficacy of the Strong Hearts program up to 2 years after program completion. All study participants who initially completed the Strong Hearts program between 2020 and 2021 (n=128) were contacted at 12months and 24months following the date of program completion. A phone survey was conducted to see if any significant post-cardiovascular events or readmissions to the hospital occurred, and self-reported dates of any occurrences were recorded. Hospital readmissions and cardiac-related procedures were cross-referenced with the hospital's electronic medical record. A chi-square goodness-of-fit analysis was utilized to compare the observed rates of categorical outcomes vs. expected rates yielded from the empirical literature. The rate of all-cause readmission at 6months post-program completion was 2/120 (1.7 %), compared to the expected rate of 50 %, χ2(1) = 112.13, p<0.001. The readmission rate at 1 year post-program completion was 17/120 (14.2 %), vs. the expected rate of 45 %, χ2(1) = 46.09, p<0.001, and at 2 years post-program completion, the readmission rate was 24/120 (20.0 %) compared to the expected rate of 53.8 %, χ2(1) = 56.43, p<0.001. Ten participants (8.3 %) had a subsequent cardiac procedure within 2 years of completing the program, including two requiring percutaneous coronary intervention (1.7 %) and eight requiring coronary artery bypass grafting (CABG, 6.7 %), compared to the expected rates of 13.4 and 57.74 %, χ2(1)=153.08, p<0.001, respectively. Mortality at 2 years post-program completion was 2/128 (1.6 %), compared to 23.4 %, χ2(1)=34.13, p<0.001. Efficacy of the Strong Hearts program continued at 6months, 1 year, and 2 years post-program completion in terms of all-cause readmission, subsequent cardiac event, and all-cause mortality.

Impacts of Hospital Volume and Patient-Hospital Distances on Outcomes of Older Adults Receiving Percutaneous Microaxial Ventricular Assist Devices for Cardiogenic Shock.

Background: Percutaneous microaxial ventricular assist devices (pVAD) have the potential to reduce mortality of patients with cardiogenic shock (CS). However, the association between the distribution of pVAD-performing centers and outcomes of CS has not been explored. Methods: This observational study included Medicare fee-for-service beneficiaries aged 65-99 years treated with pVAD for CS from 2016 to 2020 and examined the associations between patient outcomes and two exposure variables: hospitals' procedure volumes of pVAD and patient-hospital distances (in quintiles [Qn]). We developed Cox proportional hazard regression for 180-day mortality and heart failure (HF) readmission rates and multivariable logistic regression for in-hospital outcomes, adjusting for patient demographics, comorbidities, concomitant treatments, and hospital characteristics, including CS volume, teaching status, and the ability to perform extracorporeal membrane oxygenation. Results: A total of 6,637 patients with CS underwent pVAD at 1,041 hospitals, with the annualized hospital volume ranging widely from 0.3 to 55.6 cases/year. Patients treated at higher-volume centers experienced lower 180-day mortality compared with patients treated at lower-volume centers (Qn1=reference; Qn2: adjusted hazard ratio [aHR], 0.88; 95% confidence interval [CI], 0.79-0.97; Qn3: aHR, 0.88; 95% CI, 0.79-0.98; Qn4: aHR, 0.88; 95% CI, 0.78-0.99; Qn5: aHR, 0.84; 95% CI, 0.74-0.95; p-for-trend, 0.026), while we found no evidence that patient-hospital distances were associated with mortality (Qn1=reference; Qn2: adjusted hazard ratio [aHR], 0.99; 95% confidence interval [CI], 0.89-1.09; Qn3: aHR, 0.94; 95% CI, 0.85-1.04; Qn4: aHR, 1.01; 95% CI, 0.92-1.11; Qn5: aHR, 0.91; 95% CI, 0.82-1.01; p-for-trend, 0.160). We found no evidence that the hospital volume and patient-hospital distances were associated with in-hospital bleeding, intracranial hemorrhage, or renal replacement therapy initiation. Conclusions: Hospital volume was more strongly associated with mortality than patient-hospital distances, suggesting that rational distribution of pVAD-performing centers while ensuring adequate procedure volumes may optimize patient mortality.

Impact of skilled nursing facility quality on Medicare beneficiaries with dementia: Evidence from vacancies.

People living with dementia are less likely to be admitted to high-rated nursing homes than people without dementia, despite their increased care needs. We investigated the effect of admission to nursing homes with higher staffing ratings on adverse outcomes for individuals with and without dementia post-hospitalization. Among Traditional Medicare beneficiaries discharged to nursing homes between 2011 and 2017, we examined the relationship between facility staffing star-ratings and short-term readmission and mortality using an instrumental variables approach to account for selection bias. The instrumental variables were the number of nearby vacant beds in high-rated facilities. Admission to a higher-rated nursing home lowered post-discharge mortality risk at 90 days and reduced 30- and 90-day readmission. Point estimates were larger for people with dementia. Findings underscore the need for enhancing direct care staffing in nursing homes and addressing access disparities, particularly for individuals with dementia who benefit significantly from high-quality care. We assessed how admission to nursing homes with higher staffing ratings impacted outcomes for individuals with and without dementia by exploiting variation in local bed vacancies as a source of quasi-random assignment. For both persons with and without dementia, adjusted short-term mortality and readmission rates were lower among those discharged to nursing homes with higher staffing ratings. Effects were larger for persons with dementia, indicating welfare loss from inequitable access to higher-rated nursing homes. Increasing staffing in nursing homes and reducing disparities for persons with dementia is essential for enhancing both equity and value.

Comorbidity Patterns in Chronic Obstructive Pulmonary Disease and Their Associations with Service Utilization

Background The prevalence of combinations of comorbidities and their associations with inpatient service utilization and readmission among patients with chronic obstructive pulmonary disease (COPD) have not been extensively examined. To address this gap in knowledge, an observational prospective study was conducted using retrospective data. Aims To identify patterns of comorbidities linked to length of hospital stay, daily expenses, and one-year readmission. Methods The 30 most common comorbidities were identified in patients with secondary diagnoses using the association rule mining (ARM) method. Regression models were used to examine the relationships between combinations of comorbidities and service utilization, with adjustments for covariates. Results The five most prevalent comorbidities were pulmonary heart disease (40.99%), ischemic heart disease (38.97%), heart failure (36.77%), hypertension (34.11%), and respiratory disorders (19.12%). Most combinations of comorbidities identified by ARM showed significant associations with an extended length of stay (>13 days), increased daily expenses (>930 CNY), and reduced readmission rates. Among these combinations, glycoprotein metabolism disorder had the strongest association with prolonged length of stay (adjusted odds ratio [aOR]): 1.89, 95% confidence interval [CI]: 1.82–1.95). Conversely, the combination of other brain diseases and respiratory failure was linked to higher daily expenses (aOR: 11.34, 95% CI: 10.58–12.15), and the presence of pulmonary heart disease was associated with elevated one-year readmission rates (aOR: 1.41, 95% CI: 1.37–1.46). Conclusion Common combinations of comorbidities among inpatients with COPD were identified from an extensive collection of discharge medical records. Furthermore, the associations between comorbidities, inpatient service usage, and readmission rates were determined.

Cholecystectomy with the Hugo™ robotic-assisted surgery system: the first general surgery clinical study in Korea.

The Hugo™ Robotic-Assisted Surgery (RAS) System is an emergent device in the robotic surgery field. This study aims to describe the first general surgery-focused clinical study in Korea using the novel Hugo™ RAS System. This study was a prospective, single-center, single-arm, confirmatory clinical study conducted at Seoul National University Hospital where 20 cholecystectomies were performed. To evaluate the safety and performance of the Hugo™ RAS System the incidence of conversion to laparoscopy or open surgery, major complication (Clavien-Dindo Grade ≥ III) rate, overall complication rate, readmission rate, and reoperation rate were evaluated. All parameters were assessed within 30 days post-procedure. Any device deficiencies encountered during our initial experience and device data such as setup, console, and operative times were also reported. We confirmed that our trial achieved the primary objective with a success rate of at least 95%. This was accomplished with no conversions to other types of surgery due to serious system malfunction and with only one major complication within 24 h post-procedure. The 20 consecutively enrolled patients had a median age and BMI of 58 years old and 23.9 kg/m2, respectively. The major complication rate was 10% (2/20 patients), the overall complication rate was 15% (3/20 patients), the readmission rate was 15% (3/20 patients), and the reoperation rate was 0% (0/20 patients). None of the complications were definitively device related. The median setup, console, and operative times were 16, 17, and 55 min, respectively. The device deficiency rate was 15% (3/20 patients), but all device deficiencies were minor, occurred before the first incision, and did not present a risk to the patient. Based on our initial experience with the Hugo™ RAS System, cholecystectomy is feasible and safe. This trial is registered with ClinicalTrials.gov (NCT05715827).

The relationship between daily blood glucose fluctuation and readmission in patients with acute coronary syndrome

Abstract Background Although the comprehensive diagnos and treatment of patients with acute coronary syndrome(ACS) has been greatly improved,the morbidity and mortality are still high. Previous literature has reported that about 70-75% of patients diagnosed with acute coronary syndrome have abnormal blood glucose metabolism1,and there existed gender differences. At present, most research results showed that elevated blood glucose is related to the prognosis of ACS. However, further intervention studies indicated that simply strengthen the reducement of blood glucose did not improve prognosis of these patients2. Glucose fluctuations, another dimension of blood glucose, reflect acute changes in blood glucose. However, there are few studies on the effect of blood glucose fluctuation on the prognosis of patients with ACS. Purpose This study aimed to explore the relationship between seven daily fluctuations of blood glucose and readmission in ACS patients. Methods In this study, a total of 664 patients admitted to our University from January 1, 2019 to December 31, 2019 were included and their blood glucose was monitored seven times a day during their hospitalization. The coefficient of variation of blood glucose (CV) was calculated from the results of seven daily blood glucose monitoring to represent the daily fluctuation of blood glucose. Univariate and multivariate regression analyses were performed to determine whether CV was an independent risk factor for re-hospitalization. In addition, the area under the curve (AUC) was used to evaluate the predictive efficacy of CV for outcome events. Finally, we performed a subgroup analysis based on gender and diabetes status to assess the association between CV and readmission in each subgroup. Results After a median follow-up of 21 months, the rate of readmission was 38.4%. Unstable angina pectoris (71.4%) and heart failure (16.4%) were the most common reasons for readmission. Patients with greater CV levels typically exhibited lower fasting blood glucose, higher post breakfast blood glucose, and higher admission blood glucose.The readmission rate increased with the increasing blood glucose variability after the cox regression analysis. Moreover, independent of glycated hemoglobin,CV could predict the risk of readmission in patients with ACS.When using 26.66% as the cutoff point of CV, the study population was divided into two groups and showed a significant differentiation for rehospitalization.In subgroup analysis, there was no significant association between seven daily blood glucose fluctuations and readmission in female and non-diabetes mellitus patients with acute coronary syndrome. Conclusions Besides some normal blood glucose index,seven daily fluctuations of blood glucose was associated with readmission in ACS patients. ACS patients who were male and combined with diabetes were more likely to be readmitted if their CV levels were greater.

Exercise intolerance at hospital discharge as a predictor for readmission and mortality after aortic aneurysm repair

Abstract Background As procedures of aortic aneurysm repair have advanced, an increased number of surgeries performed for older patients and those with comorbidities and low activities of daily living. Conversely, since these patients frequently suffer from difficulty returning to their daily activities after the surgery, physical function is considered an important indicator for risk classification and treatment effect evaluation. However, in patients following aortic aneurysm repair, the association between physical performance and clinical outcomes is not thoroughly evaluated. Purpose We aimed to clarify whether physical function at hospital discharge predicted clinical outcomes, including readmission rates and mortality, in patients following aortic aneurysm repair. Methods This was a single-centre cohort study. We included the patients admitted to a tertiary hospital to undergo surgery or endovascular repair for aortic aneurysm and who received cardiovascular rehabilitation during hospitalisation. As patient characteristics during hospitalisation, age, sex, body mass index (BMI), urgent or standby surgery, surgical type (open repair or endovascular), and comorbidities were obtained from medical records. We also reviewed 6-minute walk distance (6MWD) as physical function at hospital discharge, and 6MWD &amp;lt;300 m was defined as exercise intolerance. The primary and secondary endpoints were readmission and death for all causes, respectively. The multivariate Cox regression analysis was used to examine whether exercise tolerance predicted the endpoints. Results The 365 patients were studied for analysis. Exercise intolerance was observed in 107 patients (29.3 %). During the median follow-up period of 2.3 years, readmission and mortality for all causes occurred in 161 (44.1 %) and 39 (10.7 %), respectively. After adjusting for patient characteristics, including age, sex, BMI, urgent or standby surgery, and surgical type, exercise intolerance defined by 6MWD &amp;lt;300 m was significantly associated with higher mortality (adjusted hazard ratio [aHR]: 2.21, 95% confidence interval [CI]: 1.05–4.66, Figure 1-A) and readmission rates (aHR: 1.63, 95% CI: 1.13–2.34, Figure 1-B). Conclusions In patients following aortic aneurysm repair, exercise intolerance at hospital discharge independently predicted readmission and death for all causes. Our findings suggest that physical function after the aortic aneurysm repair is a useful predictor for patient risk classification and an indicator for treatment effect evaluation.

A nurse-led intervention improves quality of life and reduces arrhythmic recurrences in patients undergoing atrial fibrillation ablation. Results of the NURSECAT-AF randomized clinical trial

Abstract Background/Introduction Atrial fibrillation (AF) is a prevalent condition that can lead to a decrease in quality of life and frequent re-hospitalizations. Some data suggest that integrated care nurse-led may blunt these consequences in unselected patients with AF, but not all studies support this. While AF ablation is becoming a cornerstone treatment for symptomatic patients with AF, it is unclear what impact a nurse-led intervention would have on these, quite likely, more receptive patients. Purpose To assess the impact of nurse-led intervention on quality of life among AF patients undergoing ablation. Methods We conducted a single-centre prospective randomised clinical trial to test the effect of an expert nurse-based intervention consisting of an educational programme on AF, support for the patient undergoing cardiac ablation to ensure its success, and management of risk factors associated with this arrhythmia. The control group underwent standard medical follow-up. Patient selection was based on chronological order. Only patients who underwent their first ablation and did not have heart failure were included. The primary endpoint was quality of life at 12 months post-ablation using the Arrhythmia-Specific Scale in Tachycardia and Arrhythmia (ASTA) questionnaire (higher values denote impaired quality of life). Secondary endpoints were AF knowledge and satisfaction at 15 days post-ablation using validated instruments, symptoms using the ASTA questionnaire as well, and readmissions rates, emergency room visits, and AF recurrence rates over a one-year period. Results 116 patients were screened (50 were excluded mostly because were re do). A total of 66 patients were eventually included and randomized (33 per arm; mean age [mean±SD] 63±10 years; 44 men [67%]). At 12 months, quality of life was significantly better in the intervention group than in the control group (4.5 ± 6.1 vs 0.57 ± 2.3, respectively, p=0.001)(Figure). Furthermore, satisfaction levels (17 ± 4.1 vs 12.7 ± 5.4, p&amp;gt;0.001) and disease knowledge (20.5 ± 5.1 vs 15.9 ± 4.5, p&amp;lt;0.001) were higher in the intervention group. Patients in the control group experienced a higher symptom burden during the first year (0.6 ± 1.5 vs 3.8 ± 4.5, p&amp;lt;0.001. Relevant clinical endpoints such as readmissions (3% vs 18.2%, p=0.046), emergency room visits (21.2% vs 57.5%, p=0.021), and arrhythmia recurrences (15.2% vs 45.5%, p=0.02) were all significantly lower in the intervention group. Conclusion(s) Nurse-led integrated care for patients undergoing AF ablation yields substantial improvements in quality of life and symptomatic relief at one year post-procedure. Additionally, it enhances patient knowledge of AF and satisfaction levels, and reduces readmissions, emergency room visits, and arrhythmia recurrences.

Cardiovascular disease history as a predictor for adverse outcomes in frail older adults admitted to acute geriatric settings: 12-month outcomes from an Australian frailty registry

Abstract Introduction Frailty is common in older adults with cardiovascular disease (CVD), with prevalence between 25-62% (1). The incidence of CVD increases with age, yet the outcomes of frail older adults with a history of CVD who present to acute geriatric settings, is not well understood. Purpose To report the association of CVD and rehospitalisation and/or mortality at 12 months in a cohort of frail older adults enrolled in an Australian frailty registry. Methods A convenience sample of participants enrolled in the frailty registry, with 12-month follow-up completed. The frailty registry is a prospective cohort study of adults admitted to the rehabilitation and aged care departments at two Australian hospitals. Frailty was assessed using the Clinical Frailty Scale (CFS), a score of 1-4 is ‘non-frail’, 5-6 is ‘mild-moderately frail’ and 7-9 is ‘severely frail’ (2). For this study, ‘CVD’ was defined as having a history of either heart failure, stroke, or atrial fibrillation. The cumulative incidence of first rehospitalisation and/or death during the first 12 months post discharge was estimated using one minus the Kaplan-Meier estimate of the survival function. Association between CVD (history of CVD, and type of CVD condition) and the composite endpoint were analysed. Adjusted Hazard Ratios (HRs) and 95% confidence intervals (CIs) were estimated using multivariable Cox models incorporating variables of interest and potential confounders. Results A total of 592 participants were included, median age was 82 years, 59% (n= 349) were female. The majority were frail with 50% (n= 295) classified as mild-moderately frail and 21% (n= 123) classified as severely frail. Almost half (45%, n= 265) had a history of CVD. The incidence of frailty (CFS score ≥5, mild-severely frail) was higher in those with CVD compared to those without CVD (76% vs 66%). A history of CVD was significantly associated with higher rate of first readmission or death within 12 months, compared to no history of CVD (p=0.017) (Figure 1). Of the three CVD conditions, heart failure was the only independent predictor of the composite endpoint (HR 1.60 [CI 1.14 -2.24], p=0.007). A CFS score of mild-moderately frail (HR 1.51 [CI 1.18 - 1.93, p=0.001) and severely frail were also independent predictors of the composite endpoint (HR 1.83 [CI 1.35- 2.48], p=&amp;lt;0.001) (Table 1). Conclusions A history of CVD has a significant impact on adverse outcomes in frail older adults admitted to acute geriatric settings. Frailty according to the CFS was independently predictive of rehospitalisation and mortality in this cohort. Heart failure was the only independent predictor of the composite endpoint. These findings underscore the importance of identifying and addressing CVD and in the context of frailty, emphasising the need for targeted interventions to improve outcomes in this vulnerable population.Figure 1.Table 1.

Transcatheter vs. surgical aortic valve replacement in patients with aortic stenosis and cardiogenic shock.

Patients with aortic stenosis (AS) and cardiogenic shock (CS) are an extremely high-risk population with a poor prognosis in the absence of definitive therapy. We aimed to compare the outcomes of transcatheter aortic valve replacement (TAVR) with those of surgical aortic valve replacement (SAVR) in patients with AS-CS. We queried the Nationwide Readmission Database (2016-21) to identify patients hospitalized for AS-CS who underwent isolated TAVR or SAVR. In-hospital outcomes of TAVR vs. SAVR were compared using multivariable regression and propensity-matching analyses. Ninety-day readmissions were compared using a Cox proportional hazards regression model. A total of 16 161 patients were hospitalized for AS-CS, of whom 6470 (40.0%) underwent isolated TAVR and 9691 (60.0%) underwent isolated SAVR. From 2016 through 2021, the proportion of TAVR increased from 29.5 to 46.5% and the proportion of SAVR correspondingly decreased in AS-CS (Ptrend < 0.01). After adjustment for baseline characteristics, TAVR was associated with lower odds of stroke [adjusted odds ratio (aOR) 0.63, 95% confidence interval (CI) 0.47-0.84], acute kidney injury (aOR 0.80, 95% CI 0.69-0.93), and major bleeding (aOR 0.54, 95% CI 0.40-0.71) and higher odds of vascular complications (aOR 1.56, 95% CI 1.23-1.97) compared with SAVR. In-hospital mortality, myocardial infarction, permanent pacemaker placement, and 90-day all-cause and heart failure readmissions showed similar rates between TAVR and SAVR. However, hospital length of stay was shorter and total costs and non-home discharges were lower with TAVR than with SAVR. This nationwide observational analysis showed that TAVR is increasingly performed in patients with AS-CS and is associated with similar rates of in-hospital mortality and 90-day readmissions but lower rates of in-hospital complications and resource utilization compared with SAVR.

Readmission and mortality during the first year after an acute stroke: A prospective cohort study from Cameroon.

Hospital readmission after discharge for stroke is associated with high morbidity and mortality. There is a paucity of data on the burden of stroke readmission in most sub-Saharan African countries. We aimed to determine the rate, reasons and predictors of hospital readmission and the mortality rate within 12 months of discharge among stroke survivors in Cameroon. This prospective cohort included patients who survived hospitalization for an acute stroke and who were discharged from two referral hospitals in the capital city of Cameroon between January 2013 and December 2013.We performed logistic regression analysis to identify demographic and clinical factors associated with readmission within 1 year of discharge and causes of readmission. Of the 254 consecutive patients admitted for acute stroke, 198 were discharged alive. There were 107 (54%) males, and their mean age (SD) was 61.7 (13.9) years (range: 10 to 95 years). A total of 30 (15.2%) patients were readmitted following discharge from the index admission over a mean follow-up time of 286.9 (127.6) days. Of these, 14 (46.7%) were discharged and 16 (53.3%) died after readmission. Thirty percent (30%) of readmissions occurred within the first month. The most frequent causes of readmissions were infections (30%) and recurrent stroke (26.7%). Factors associated with readmission in bivariate analysis were initial admission temperature > 37.5°C (risk ratio [RR]: 1.3, p = 0.021) and initial admission Glasgow Coma Score < 14 (RR: p = 1.23, p = 0.019). After stratified adjustment for age and sex, temperature > 37.5°C (adjusted RR: 1.3, 95% CI: 1-1.7, p = 0.036) and GCS <14 (adjusted RR: 1.23, 95% CI: 1-1.6, p = 0.041) were associated with readmission. Readmission after discharge for stroke was common with nearly one third occurring within the first month and more than half dying following readmission. The most common causes of readmission were infections and recurrent stroke.

Safe transition home after transcatheter aortic valve implantation feasibility (START-F) study: Very early self-reported function and recovery status after early discharge

Abstract Background Despite significant excellent outcomes and significant improvements in rapid recovery protocols and early discharge, rates of 30-day readmission after transcatheter aortic valve implantation (TAVI) remain stubbornly high. There can be numerous drivers for readmission in older people with valvular heart disease; the time of transition home is the period of greatest risk when patients are most vulnerable to repeat hospitalization. We sought to assess patients’ early recovery (&amp;lt; post-procedure day 3) to inform the evaluation of a nurse-led telephone intervention to mitigate the risks of 30-day readmission after early (1 day) discharge TAVI. Methods We conducted a prospective observational cohort feasibility study in five Canadian TAVI programs to ascertain acceptability, compliance, delivery of the intervention, recruitment and retention. In this preliminary report, we assessed key indicators of patients’ status at the time of discharge and functional status in their early recovery. Results We recruited 188 participants, mean age 81.6 years (SD=7.0), 41.5% women with baseline mean KKCQ 53.4 (SD=20.1). Patients were admitted on the day of the procedure, and underwent TAVI with a balloon-expandable (n=146, 77.6%) or self-expanding (n=30, 16.0%) device, with local anaesthesia +/- light sedation (n=171, 90.1%) or general anaesthesia (n=17, 9.0%). There was 1 in-hospital death (0.5%) and 182 (97.4%) were discharged home. At the time of the 3-day telephone follow-up, 168 (95.5%) reported that an individual had stayed with them during the first 24 hours [spouse: 85 (48.9%); friend: 77 (44.3%)], and 165 (93.3%; missing: 11) were able to complete all activities of daily living, including cooking their own meals (n=80, 45.5%). Self-reported energy was low/very low for 49 participants (26.1%), moderate for 93 (52.8%), and high/very high for 34 (18.1%), with 104 (55.3%) describing feeling somewhat or quite a bit better than before TAVI, and 24 (12.8%) somewhat or quite a bit worse. Bruising was present in 120 participants (68.6%) and 137 (78.8%) had removed their bandage as instructed. 18 participants were readmitted within 30 days, including 14 cardiac-related events. Conclusion This is one of the first reports of TAVI patients’ self-reported function following next-day discharge, providing novel evidence that most patients describe safe self-care and very early improved functional status. Research is needed to identify and support patients who are at higher risk of poorer trajectories of recovery and readmission, and report the feasibility of a nurse-led intervention to mitigate these risks.

Explainable machine learning and multi-modal data for predicting readmission in patients with heart failure

Abstract Background Cardiovascular diseases (CVDs) are among the leading causes of mortality and morbidity globally, with an estimated 1 million hospital admissions for CVD in England in 2019/20, leading to 5.5 million bed days. In addition, patients with CVDs have a notably high rate of hospital readmission, with approximately one in four patients experiencing heart failure (HF) being readmitted within one month of discharge. We explored whether machine learning models trained on electrocardiogram (ECG) and patient electronic health records (EHRs) can support decision-making and risk management and ultimately improve health outcomes for HF patients. Purpose The project aims to develop a machine learning model to predict health outcomes for HF patients. To test the hypothesis, we trained and tested an explainable machine learning model to predict the risk of mortality and hospital readmission rate for HF patients. Methods We used EHR data and tabulated ECG records to train an XGBoost model to predict the risk of 30-day mortality and 30-day hospital readmission for HF patients. EHR data from a cohort of 2,868 patients with their ECG records were used for model development. We extracted a total of 78 features from the ECG data, such as heart rate variability (HRV), P-wave durations, and QT intervals. These ECG features were combined with coded and free-text EHR data (e.g., demographic information, diagnosis, medication history, and lab results) and used as tabular inputs to the XGBoost model. Of the 2,868 patients, an internal set of 574 patients stratified by age, sex, and health outcomes (30-day mortality and 30-day hospital readmission) were held out for testing. Results Among 2,868 HF patients with 10-year follow-up, 1065 patients were reported for mortality or hospital readmission within 30 days of discharge. When the machine learning model was trained on ECG data in addition to EHR data, the model was able to predict patient mortality and hospital readmission rate in the test set with an area under the curve (AUC) of 0.91 and 0.70, respectively. For mortality prediction, the model achieved a sensitivity and specificity of 0.81 and 0.82, respectively, when employing an operating point with minimum difference between the sensitivity and specificity. When the threshold was adjusted to favor sensitivity at 0.91, the model specificity decreased to 0.74. The machine learning model also identified high sensitive troponin levels, QT dispersion, and lactate dehydrogenase levels as features of high importance for predicting the outcomes for HF patients. Conclusions Our developed machine learning model was able to predict mortality and readmission risks in HF patients using multi-modal data. Upon further validation, the machine learning model has the potential to be tested for supporting clinical decision-making and risk management for HF patients.ROC CurveFeature Importance

Sex differences in cardiovascular-related hospital readmissions, adverse events and interventions within 1 year after ST-elevation myocardial infarction

Abstract Introduction Reducing cardiovascular (CV)-related hospital readmissions as well as adverse events following ST- elevation myocardial infarction (STEMI) is a critical goal to improve outcomes as well as quality of life and reduce healthcare costs. We aimed to study the rates of CV-related readmissions, adverse events and interventions after STEMI in women and men. Methods We included STEMI patients from the Acute Myocardial Infarction in Switzerland (AMIS) Plus registry, who underwent percutaneous coronary intervention (PCI) between 2013 and 2022 and participated in a telephone-based follow-up (FU) interview 1-year after hospital admission. Patients were asked if they had hospital readmissions (if yes: planned/emergency/both) during FU for any CV reason, if they suffered a reinfarction or stroke and if they had any or several of the following interventions: PCI, coronary artery bypass graft, pacemaker and/or defibrillator implantation. These self-reported data were analysed using descriptive statistics and logistic regression models were used to study the relationship between patient characteristics and hospital readmissions. Results Of 4388 PCI-treated STEMI patients contacted for FU, 275 (6.3%) were unreachable, 118 (2.7%) died, and 223 (5.1%) had no data on readmissions; therefore 3772 patients (78.4% men, 21.6% women) were analysed. Women were older (mean (SD) age at event: 68.4 (12.0) vs. 62.5 (11.5) years) while the Charlson Comorbidity Index (CCI) was similar (CCI&amp;gt;1: 14.0% vs. 12.1%, n.s.). The mean rate of patients readmitted for CV reasons was 22.1%; 20.4% for women and 22.6% for men (p=0.198). Overall, 8.8% had at least one emergency and 13.9% at least one planned readmission. The occurrence of a planned readmission was significantly lower in women (11.1% vs. 14.7%, p=0.008). Patients with a readmission had during the index hospitalisation higher rates of in-hospital complications (18% vs. 14%), heart failure (NYHA III+IV) (2.2% vs. 0.8%), diabetes (18% vs. 14%) and peripheral arterial disease (3.9% vs. 2.5%). A multivariable adjusted model that included these factors together with age and sex identified heart failure (OR: 2.5, CI 1.34-4.66, p=0.004) and in-hospital complications (OR:1.4, CI 1.12-1.70, p=0.003) as independent predictors of hospital readmission. The rates of the analysed adverse events and interventions were similar between sexes except that women had less often a PCI during the FU period (13.2% vs. 16.6%, p=0.026). Conclusion Over the last 10 years, on average 1 in 5 patients had at least one CV-related readmission within 1 year after PCI-treated STEMI, while no overall sex-difference was found. Heart failure and in-hospital complications were independent predictors of readmission. Women had less often planned hospital readmissions and additional PCIs.

Relapse of infective endocarditis after cardiac implantable electronic device removal compared to a conservative strategy

Abstract Background According to current guidelines, complete removal of cardiac implantable electronic device (CIED) should be considered in patients with valvular infective endocarditis (IE), accounting for the identified pathogen and need for valve surgery (Class IIa recommendation). Unselected longitudinal data are needed to assess this strategy. Purpose To examine IE readmission after IE discharge according to status of CIED removal in patients with conservatively treated IE. Methods Using Danish nationwide registries, we identified patients aged ≥18 years with first-time IE from 2010-2021. We included patients with conservatively treated IE and a CIED, who were alive at IE discharge. Patients who underwent CIED removal during IE admission were compared to those without removal, examining the study outcome of IE readmission within six months after IE discharge. An initial blanking period of 14 days was applied after IE discharge. The Aalen-Johanson estimator and multivariable Cox regression models were used to determine cumulative incidences and adjusted hazard ratios (HRs) of IE readmission according to status of CIED removal, respectively. Results Among 6,843 patients with first-time IE, 5,731 (83.7%) were conservatively treated. Of these, 1,201 (21.0%) had a CIED, of which 205 (17.1%) died during IE admission. Thus, the final study population comprised 996 patients alive at IE discharge. The median age of the study population was 75.5 years (interquartile range [IQR]: 67.9-82.0), and 753 (75.6%) were males. In total, 574 (57.6%) patients underwent CIED removal during IE admission. Patients who underwent CIED removal were younger, compared to patients without CIED removal, 73.1 years (IQR: 65.7-79.1) versus 79.0 years (IQR: 71.3-85.1), respectively. The six-month cumulative incidence of IE readmission was 2.0% (95% confidence interval [CI]: 1.1-3.5%) in patients who underwent CIED removal versus 6.1% (95% CI: 4.0-8.9%) in patients without CIED removal (P-value=0.001) (Figure 1). CIED removal was associated with a significantly lower six-month rate of IE readmission, compared to no CIED removal (HR: 0.36 [95% CI: 0.17-0.77]). Relapse bacteraemia (including IE) with the same microorganism as first-time IE occurred in 2.2% of patients who underwent CIED removal and in 5.4% of patients without CIED removal. Staphylococcus aureus was the most common microorganism in 33.3% of patients with relapse bacteraemia who underwent CIED removal. Conclusions In this nationwide study, the six-month rate of infective endocarditis (IE) readmission was three-fold lower in patients who underwent cardiac implantable electronic device (CIED) removal, compared to patients without CIED removal. The current findings suggest that CIED removal is associated with lower risk of relapse of IE in patients with conservatively treated IE. These results are in line with current guideline recommendations. However, more randomized clinical trial data are needed.

Routine use of ultrasound-assisted catheter-directed thrombolysis for the management of intermediate-high risk pulmonary embolism: a service evaluation project

Abstract Background Intermediate-high risk Pulmonary Embolism (PE) has considerable morbidity. Conservative management could be sub-optimal. Ultrasound-Assisted Catheter-Directed Thrombolysis (UACDT) is used in our centre for the routine management of this presentation. Purpose We assessed the procedure safety and short-term outcomes by reviewing locally performed procedures. Methods This is an observational retrospective cohort study, with a historic control group. Our centre is a District General Hospital (DGH) in the United Kingdom, and we receive referrals from local acute hospitals. Since the introduction of this service in June 2018 until November 2023, 129 patients (2 patients/month) received routine management with UACDT for intermediate-high risk PE. The controls are 75 acute PE patients of comparable risk classes, managed from January to December 2016. We assessed procedural and in-hospital outcomes including minor, major bleeding/complications and death. We also assessed Length of Stay (LoS) in hospital, recurrent Venous Thrombo-Embolism (VTE) and re-admission rates for recurrent PE at 30 days. Reduction of oxygen requirements and improved estimated systolic Pulmonary Artery Pressure (sPAP) post-procedure were assessed as surrogate measures. Continuous variables were analysed with a Mann-Whitney U test, and categorical variables with a Chi-square Test. Results Baseline demographics are listed in Table 1. Mean duration between CT Pulmonary Angiography (CTPA) and the UACDT procedure was 1.6 (±SD 1.4) days, including inter-hospital transfer. Only 6% (8/129) of UACDT cohort received ≤12 mg standard alteplase dose. In the control group, 4% (3/75) of patients received standard 100mg systemic thrombolysis. There was no significant difference in the rates of minor (p= 0.9), major bleeding/complications (p= 0.8), or death (p= 1.0) between both groups. There was also no significant difference in rates of recurrent VTE (p= 1.0) or re-admission within 30 days for PE (p=0.1) (Table 2). LoS in hospital data were ratified, to exclude inappropriate delays (e.g. physiotherapy requirements, etc). We used the date when the patient was declared medically fit for discharge, and no significant difference was noted (p= 0.2). This was confirmed with a regression analysis of UACDT treatment effect (p= 0.9, CI= -3.5 to 3.1). Nonetheless, there was a 25% reduction of median LoS in hospital from 8 days in the controls to 6 days with UACDT. The proportion of patients requiring O2 was also reduced from 69% (89/129) to 41% (54/129) on day 1 post-procedure. A significant reduction of the estimated sPAP by TTE post-procedure was detected by a mean of 10.4 (±SD 13.9) mmHg (p= &amp;lt;0.01). Conclusion UACDT is generally safe with low complications rate. Compared to the control group, there was a reduction in absolute deaths and median LoS in hospital. This can be secondary to the significant acute reduction of systolic pulmonary artery pressure identified.
