ABCD2-I Score Predicts Unplanned Emergency Department Revisits within 72 Hours Due to Recurrent Acute Ischemic Stroke

Background: the ABCD2 score is valuable for predicting early stroke recurrence after a transient ischemic attack (TIA), and Doppler ultrasound can aid in expediting stroke triage. The study aimed to investigate whether combining the ABCD2 score with carotid duplex results can enhance the identification of early acute ischemic stroke after TIA. Methods: we employed a retrospective cohort design for this study, enrolling patients diagnosed with TIA who were discharged from the emergency department (ED). The modified ABCD2-I (c50) score, which incorporates a Doppler ultrasound assessment of internal carotid artery stenosis > 50%, was used to evaluate the risk of acute ischemic stroke within 72 h. Patients were categorized into three risk groups: low risk (with ABCD2 and ABCD2-I scores = 0–4), moderate risk (ABCD2 score = 4–5 and ABCD2-I score = 5–7), and high risk (ABCD2 score = 6–7 and ABCD2-I score = 8–9). Results: between 1 January 2014, and 31 December 2019, 1124 patients with new neurological deficits were screened, with 151 TIA patients discharged from the ED and included in the analysis. Cox proportional hazards analysis showed that patients in the high-risk group, as per the ABCD2-I (c50) score, were significantly associated with revisiting the ED within 72 h due to acute ischemic stroke (HR: 3.12, 95% CI: 1.31–7.41, p = 0.0102), while the ABCD2 alone did not show significant association (HR: 1.12, 95% CI: 0.57–2.22, p = 0.7427). Conclusion: ABCD2-I (c50) scores effectively predict early acute ischemic stroke presentations to the ED within 72 h after TIA.

Can Timely Outpatient Visits Reduce Readmissions and Mortality Among Heart Failure Patients?

Outpatient follow-up after a hospital discharge may reduce the risk of readmissions, but existing evidence has methodological limitations. To assess effect of outpatient follow-up within 7, 14, 21 and 30days of a hospital discharge on 30-day unplanned readmissions or mortality among heart failure (HF) patients; and whether this varies for patients with different clinical complexities. We analyzed medical records between January 2016 and December 2021 from a prospective cohort study. Using time varying mixed effects parametric survival models, we examined the association between not having an outpatient follow-up and risk of adverse events. We used interaction models to assess if the effect of outpatient follow-up visit on outcomes varies with patients' clinical complexity (comorbidities, grip strength, cognitive impairment and length of inpatient stay). Two hundred and forty-one patients with advanced HF. 30-day all-cause (or cardiac) adverse event defined as all cause (or cardiac) unplanned readmissions or death within 30days of an unplanned all-cause (or cardiac) admission or emergency department visit. We analyzed 1595 all-cause admissions, inclusive of 1266 cardiac admissions. Not having an outpatient follow-up (vs having an outpatient follow-up) significantly increased the risk of 30-day all-cause adverse event. (risk [95% CI] - 14days: 35.1 [84.5,-1.1]; 21days: 43.9 [48.2,6.7]; 30days: 31.1 [48.5, 7.9]) The risk (at 21days) was higher for those with one co-morbidity (0.25 [0.11,0.58]), mild (0.67 [0.45, 1.00]) and moderate cognitive impairment (0.38 [0.17, 0.84]), normal grip strength (0.57 [0.34, 0.96]) and length of inpatient stay 7-13days (0.45 [0.23, 0.89]). Outpatient follow-up within 30days after a hospital discharge reduced risk of 30-day adverse events among HF patients, the benefit varying according to clinical complexity. Results suggest the need to prioritize patients who benefit from outpatient follow-up for these visits.

An electronic trigger to detect telemedicine-related diagnostic errors.

The COVID-19 pandemic advanced the use of telehealth-facilitated care. However, little is known about how to measure safety of clinical diagnosis made through telehealth-facilitated primary care. We used the seven-step Safer Dx Trigger Tool framework to develop an electronic trigger (e-trigger) tool to identify potential missed opportunities for more timely diagnosis during primary care telehealth visits at a large Department of Veterans Affairs facility. We then applied the e-trigger algorithm to electronic health record data related to primary care visits during a 1-year period (1 April 2020-31 March 2021). The algorithm identified patients with unexpected visits within 10 days of an index telemedicine visit and classified such records as e-trigger positive. We then validated the e-trigger's ability to detect missed opportunities in diagnosis using chart reviews based on a structured data collection instrument (the Revised Safer Dx instrument). We identified 128,761 telehealth visits (32,459 unique patients), of which 434 visits led to subsequent unplanned emergency department (ED), hospital, or primary care visits within 10 days of the index visit. Of these, 116 were excluded for clinical reasons (trauma, injury, or childbirth), leaving 318 visits (240 unique patients) needing further evaluation. From these, 100 records were randomly selected for review, of which four were falsely flagged due to invalid data (visits by non-providers or those incorrectly flagged as completed telehealth visits). Eleven patients had a missed opportunity in diagnosis, yielding a positive predictive value of 11%. Electronic triggers that identify missed opportunities for additional evaluation could help advance the understanding of safety of clinical diagnosis made in telehealth-enabled care. Better measurement can help determine which patients can safely be cared for via telemedicine versus traditional in-person visits.

Socioeconomic Deprivation and Health Care Use in Patients Enrolled in SWOG Cancer Clinical Trials

Reducing acute care use is an important strategy for improving value. Patients with cancer are at risk for unplanned emergency department (ED) visits and hospital stays (HS). Clinical trial patients have homogeneous treatment; despite this, structural barriers to care may independently impact acute care use. To examine whether ED visits and HS within 12 months of trial enrollment are more common among Medicare enrollees who live in areas of socioeconomic deprivation or have Medicaid insurance. This cohort study included patients with cancer who were 65 years or older and treated in SWOG Cancer Research Network trials from 1999 to 2018 using data linked to Medicare claims. Data were collected from 1999 to 2019 and analyzed from 2022 to 2024. Outcomes were ED visits, HS, and costs in the first year following enrollment. Neighborhood socioeconomic deprivation was measured using patients' zip code linked to the Area Deprivation Index (ADI), measured on a 0 to 100 scale for increasing deprivation and categorized into tertiles (T1 to T3). Type of insurance was classified as Medicare with or without commercial insurance vs dual Medicare and Medicaid. Demographic, clinical, and prognostic factors were captured from trial records. Multivariable regression was used, and the association of ADI and insurance with each outcome was considered separately. In total, 3027 trial participants were analyzed. The median (range) age was 71 (65-98) years, 1280 (32.3%) were female, 221 (7.3%) were Black patients, 2717 (89.8%) were White patients, 90 (3.0%) had Medicare and Medicaid insurance, and 660 (22.3%) were in the areas of highest deprivation (ADI-T3). In all, 1094 patients (36.1%) had an ED visit and 983 patients (32.4%) had an HS. In multivariable generalized estimating equation, patients living in areas categorized as ADI-T3 were more likely to have an ED visit (OR, 1.34; 95% CI, 1.10-1.62; P = .004). A similar but nonsignificant pattern was observed for HS (OR, 1.36; 95% CI, 0.96-1.93; P = .08). Patients from areas with the highest deprivation had a 62% increase in risk of either an ED visit or HS (OR, 1.62; 95% CI, 1.25-2.09; P < .001). Patients with Medicare and Medicaid were 96% more likely to have an ED visit (OR, 1.96; 95% CI, 1.56-2.46; P < .001). In this cohort of older patients enrolled in clinical trials, neighborhood deprivation and economic disadvantage were associated with an increase in ED visits and HS. Efforts are needed to ensure adequate resources to prevent unplanned use of acute care in socioeconomically vulnerable populations.

Unplanned revisits of older patients to the emergency department

IntroductionOlder patients currently represent up to 12%−24% of all emergency department (ED) visits. While increasing in number, they are also at high risk of revisits once discharged. The rate of ED revisits within 72 h is a key indicator of the quality of care in emergency medicine and varies between 1% and 15%. The reasons for ED revisits are natural course of illness, misdiagnosis, lack of homecare, and self-discharge against medical advice. However, the risk factors for ED revisits have not been fully investigated. Therefore, this study aimed to analyze the incidence of ED revisits and identify the risk factors for ED revisits within 72 h after ED discharge.MethodsIn this retrospective study, older patients (≥70 years) were consecutively enrolled if they presented with an Emergency Severity Index of 2 or 3 in a tertiary care ED in 2019, with discharge after the ED visit. The primary endpoint was the frequency of unplanned ED revisits within 72 h after ED discharge. The secondary endpoints were the reasons and potential risk factors for ED revisits. Univariate and multivariate logistic regression models were used.ResultsA total of 592 older patients were enrolled, of whom 30 (5.1%) revisited the ED within 72 h. Gastrointestinal diagnosis [odds ratio (OR), 2.9; 95% confidence interval [CI], 1.04–8.2; p = 0.043) and nausea in particular (OR, 3.5; 95% CI, 1.3–9.4; p = 0.016) were significant risk factors for ED revisits. Furthermore, discharge against medical advice (OR, 5.6; 95% CI, 1.7–18.1; p = 0.004) and ED presentation during the night (OR, 2.7; 95% CI, 1.2–6.1; p = 0.014) were significant risk factors for ED revisits within 72 h after discharge, respectively.ConclusionAlthough the frequency of ED revisits among older patients at 72 h after discharge tends to be low and most revisits were illness-related, all older patients need to be assessed for risk factors for ED revisits. Discharge should be carefully evaluated to improve patient safety and provide the best healthcare to this frail population.

Impact of virtual care on planned rechecks in a pediatric emergency department: a quality improvement project.

In the absence of accessible urgent follow-up options, emergency physicians may use an in-person recheck (planned return visit) to the Emergency Department (ED) as a safety net for discharged patients. In-person rechecks require travel, triage, and waiting time for patients and families and contribute to ED census. Many of these visits do not result in further investigation or changes in management but can provide reassurance for the family and care providers. We aimed to reduce the volume of in-person rechecks to our ED through an urgent virtual follow-up process. We conducted a quality improvement project using iterative process mapping and Plan-Do-Study-Act cycles to develop and implement a new model of care for virtual rechecks. An interdisciplinary team tested and refined the virtual care process from December 2020 to June 2022. Outcome, process and balancing measures were tracked continuously and analyzed using statistical process control. Baseline data revealed that the majority of in-person rechecks were for young infants with bronchiolitis. Post-implementation of the new process, 50% of all virtual rechecks were for respiratory illnesses. Use of virtual rechecks increased steadily to an average of 6.5 per 1000 ED visits with 58% of all rechecks now completed virtually. The number of in-person rechecks did not decrease during the study period. Virtual rechecks triggered an in-person ED visit in 5.2% of virtual recheck instances. There was no increase in unplanned return ED visits or admissions after implementation of virtual rechecks. Virtual rechecks can be safely implemented to allow urgent reassessment of patients following an ED visit. Virtual rechecks could be a useful tool for addressing planned reassessments in the pediatric ED, especially during surges of respiratory illness.

A Single Center's Experience With Spinal Anesthesia for Pediatric Patients Undergoing Surgical Procedures

PurposeTo perform a single institution review of spinal instead of general anesthesia for pediatric patients undergoing surgical procedures. Spinal success rate, intraoperative complications, and postoperative outcomes including unplanned hospital admission and emergency department visits within seven days are reported. MethodsRetrospective chart review of pediatric patients who underwent spinal anesthesia for surgical procedures from 2016 until 2022. Data collected included patient demographics, procedure and anesthetic characteristics, intraoperative complications, unplanned admissions, and emergency department returns. ResultsThe study cohort included 1221 patients. Ninety-two percent of the patients tolerated their surgical procedure without requiring conversion to general anesthesia, and 78% of patients that had spinals placed successfully did not receive any sedation following lumbar puncture. The most common intraoperative event was systolic blood pressure below 60 mm Hg (14%), but no cases required administration of vasoactive agents, and no serious intraoperative adverse events were observed. Post-Anesthesia Care Unit Phase I was bypassed in 72% of cases with a median postoperative length of stay of 84 min. Forty-six patients returned to the emergency department following hospital discharge, but no returns were due to anesthetic concerns. ConclusionsSpinal anesthesia is a viable and versatile option for a diversity of pediatric surgical procedures. We noted a low incidence of intraoperative and postoperative complications. There remain numerous potential advantages of spinal anesthesia over general anesthesia in young pediatric patients particularly in the ambulatory setting. Level of EvidenceIV. Type of StudyRetrospective cohort treatment study.

P1100 A multivariate time-dependent proportional hazard model to predict development of intestinal failure from Crohn’s Disease

Abstract Background Intestinal Failure (IF) is a rare but severe complication of Crohn’s disease (CD). Advancement in therapy has not eliminated incident IF from CD (CDIF), and risk factors for developing IF from CD are not well characterised. The Copenhagen Intestinal Failure Database contains one of the largest, comprehensively described adult CDIF cohort1 from 1973 to 2018, which can be linked with a Danish nationwide CD cohort2 to explore healthcare utilisation patterns associated with developing IF from onset of CD. Methods CDIF patients from Copenhagen Intestinal Failure Database and a nationwide CD cohort without IF were followed from CD diagnosis until IF, death, or censoring on 31/12/2018. Hospital contacts, surgeries, medication use and employment status were extracted from multiple Danish population-based registries. Unplanned hospitalisation or emergency department attendance (inpatient-contact), CD-related abdominal surgery, and stopping work for 6 months or more (in working-age CD patients, excluding full-time study and parental leave) were considered time-dependent covariates and tested for significance (p&amp;lt;0.05) in univariate proportional hazard models. Significant covariates were then modelled together with additional non-time-dependent clinical and demographic variables in multivariate proportional hazard models. Backward variable selection was performed to derive a final predictive model. Results 175 CDIF and 22845 CD patients from whom data was available were followed for 2283.1 and 293536.5 patient-years, respectively. Univariate time-dependent proportional hazard models showed that every instance of unplanned IBD inpatient contact, CD-related abdominal surgery, and stopping work was significantly associated with increased hazard of developing IF, with a hazard ratio of 4.91 (95% CI 3.54-6.80, p&amp;lt;0.001), 29.79 (95% CI 9.70-91.48, p&amp;lt;0.001) and 1.61 (95% CI 1.15-2.26, p=0.005). In multivariate analysis, earlier decade of IBD onset, unplanned IBD inpatient contacts, length of stay of the inpatient contact, CD-related abdominal surgery, complicated surgery, number of previous admissions and surgeries and previous median-long term unemployment increased the rate of developing IF (Table), whereas age and comorbidity level at CD onset, non-IBD inpatient contacts, type of surgery, biologics use, and current employment status were not found to be significantly associated with IF development. Conclusion This is the first study to demonstrate significantly increased risks of developing IF from CD from increased healthcare utilisation patterns.

The Hospitalist-Oncologist co-ManagemEnt (HOME) system improves hospitalization outcomes of patients with cancer

BackgroundThe hospitalist system has been introduced to improve the quality and safety of inpatient care. As its effectiveness has been confirmed in previous studies, the hospitalist system is spreading in various fields. However, few studies have investigated the feasibility and value of hospitalist-led care of patients with cancer in terms of quality and safety measures. This study aimed to evaluate the efficacy of the Hospitalist-Oncologist co-ManagemEnt (HOME) system.MethodsBetween January 1, 2019, and January 31, 2021, we analyzed 591 admissions before and 1068 admissions after the introduction of HOME system on January 1, 2020. We compared the length of stay and the types and frequencies of safety events between the conventional system and the HOME system, retrospectively. We also investigate rapid response system activation, cardiopulmonary resuscitation, unplanned intensive care unit transfer, all-cause in-hospital mortality, and 30-day re-admission or emergency department visits.ResultsThe average length of stay (15.9 days vs. 12.9 days, P < 0.001), frequency of safety events (5.6% vs. 2.8%, P = 0.006), rapid response system activation (7.3% vs. 2.2%, P < 0.001) were significantly reduced after the HOME system introduction. However, there was no statistical difference in frequencies of cardiopulomonary resuscitation and intensive care unit transfer, all-cause in-hospital morality, 30-day unplanned re-admission or emergency department visits.ConclusionsThe study suggests that the HOME system provides higher quality of care and safer environment compared to conventional oncologist-led team-based care, and the efficiency of the medical delivery system could be increased by reducing the hospitalization period without increase in 30-day unplanned re-admission.

Improving the quality and sustainability of home-based acute care models using virtual care technology

Importance COVID-19 has facilitated the rise of a new service model that combines HITH service provision with technology to create ‘virtual hospitals’, but evidence on the impact of this new model in terms of cost and clinical outcomes, compared to usual Hospital in the Home (HITH) care, is currently lacking.&#x0D; Objective To assess the clinical and financial impacts of virtual care technology on Hospital in the Home models of care.&#x0D; Design Quasi-experimental study comparing outcomes of a control group receiving ‘usual’ home-based acute care and a virtual care cohort using remote monitoring technology while also receiving usual Hospital in the Home (HITH) care.&#x0D; Main Outcomes and Measures Readmissions within 28 days, unplanned emergency department (ED) presentations, transfers-in to facility-based hospital beds, and average length of stay.&#x0D; Results During the study period, 151 adult and 26 paediatric patients utilised virtual care technology for the majority, or all, of their home-based acute care. Use of such technology was associated with a statistically significant reduction in risk of hospital readmission within 28 days—from 43% to 21%. The risk of hospital readmission within 28 days for the same diagnosis-related group (DRG) dropped from 18% to 4%, and the length of stay for the top three DRGs by volume decreased from a mean of 7.2 days to 4.0 days, saving an average of $3,698 per admission. Use of technology was also associated with reduced rates of unplanned ED presentations and transfers-in to traditional hospital beds compared to usual care for adults.&#x0D; Conclusions Our findings confirm there are clinical and economic benefits associated with embedding virtual care technology in Hospital in the Home (HITH) service models that warrant consideration in health systems facing capacity constraints and rising costs.

Liposuction Complications in the Outpatient Setting: A National Analysis of 246,119 Cases in Accredited Ambulatory Surgery Facilities.

Suction lipectomy (liposuction) is a popular cosmetic surgical procedure performed in the United States, but little has been documented regarding perioperative complications due to its outpatient nature. This cross-sectional study aims to analyze the most common complications that accompany liposuction-related procedures and importantly estimate the total complication rate occurring at ambulatory surgical facilities. Adult patients who experienced liposuction-related complications from 2019 to 2021 were identified in the reporting database of the global surgery accreditation authority, the American Association for Accreditation of Ambulatory Surgery Facilities (QUAD A). Patients were then divided by complication type and procedure location. Demographics and facility-specific variables were analyzed. Descriptive statistics were performed. Overall, 984 patients were included, with a mean age of 44 years (interquartile range [IQR] 37-53) and a median BMI of 28.7 kg/m2 (IQR 25.7-32.2). The overall confirmed complication rate was found to be 0.40% (984/246,119). Unplanned emergency department presentation was the most common complication overall (24%). Wound disruption was associated with the longest median procedure length (261 min), and venous thromboembolism was associated with the highest median BMI (30.1 kg/m2). The Southeast had the most complications (431), which accounted for 13/21 deaths (61.9%). Out of all complications, death was associated with the highest average annual case volume (241). Procedures that involve liposuction are associated with a variety of medical and surgical complications. Given the high frequency and variability in how liposuction is performed, a thorough assessment of complications is critical to improve the safety of this procedure.

Impact of pharmacological treatment for heart failure after myocardial recovery in arrhythmia-induced cardiomyopathy

Abstract Introduction There is scarce evidence regarding the optimal medical treatment of patients with heart failure and recovered LVEF. To date, no study has analyzed the efficacy of maintaining neurohormonal blockade in patients with arrhythmia-induced cardiomyopathy (AiCM) after LVEF normalization. Purpose The aim of this study is to analyze impact of pharmacological treatment for heart failure in preventing heart failure relapse after myocardial recovery in AiCM. Methods We analyze data from a single-center cohort of 200 patients admitted for heart failure and ventricular dysfunction initially attributed to AiCM between 2008 and 2020. Myocardial recovery was defined as an improvement in LVEF up to &amp;gt; = 50% (complete recovery) or an increase of &amp;gt; = 10% up to a value of LVEF &amp;gt;= 40% (partial recovery). Heart failure relapse was defined as a decrease in LVEF to &amp;lt;50% in those with previous complete recovery or a decrease of &amp;gt; = 10% in patients with partial recovery, unplanned Emergency Department (ED) visit or hospital admission for heart failure. As drug prescriptions are not constant over follow up, changes in medication have been recorded and time varying covariates were used for statistical analysis. A Fine and Gray competing-risk multivariate regression was performed, adjusting for initial LVEF at admission, degree of myocardial recovery (complete or partial), presence of underlying cardiomyopathy and age, considering death as competing risk. Results Over a median of 6.14 years, most of the patients had a complete myocardial recovery (n = 164; 82.0%). 24 patients (12%) had partial recovery and 12 patients (6.0%) did not show significant improvement in ventricular function. At the moment of myocardial recovery, ACEI/ARB/ARNI were prescribed in 160 patients (85.11%); beta-blockers in 170 (90.43%); ARB in 112 (59.57%); iSGLT2 in 8 (4.26%); antiarrhythmic drugs in 75 (39.89%) and Digoxin in 40 (21.28). From 188 patients with initial LVEF recovery, 64 (34.04%) had a relapse of systolic dysfunction. 65 patients (34.57%) required unplanned Emergency Department (ED) visits and 40 patients (21.28%) needed hospital admission for heart failure. Maintenance of ACEI/ARB/ARNI and beta-blockers after myocardial recovery was associated with a significant lower risk of HF relapse [sHR 0.43 (95% CI 0.26 - 0.73), p 0.002 for ACEI/ARB/ARNI]; [sHR 0.52 (95% CI 0.29 - 0.92), p 0.025 for beta-blockers]. ARM was associated with a non-significant lower risk of HF relapse [sHR 0.67 (95% CI 0.42 - 1.09), p 0.093]. Treatment with antiarrhythmic drugs [sHR 0.90 (95% CI 0.54 - 1.51), p 0.696] and Digoxin [sHR 0.90 (95% CI 0.54 - 1.51), p 0.696] did not show benefit in this study. Conclusions Maintenance of ACEI/ARB/ARNI and beta-blockers after myocardial recovery was associated with a significant lower risk of HF relapse after myocardial recovery in patients with AiCM.Risk of HF relapse - ACEI ARB ARNIRisk of HF relapse - BetaBlockers

An After-Hours Virtual Care Service for Children With Medical Complexity and New Medical Technology: Mixed Methods Feasibility Study.

Family caregivers (FCs) of children with medical complexity require specialized support to promote the safe management of new medical technologies (eg, gastrostomy tubes) during hospital-to-home transitions. With limited after-hours services available to families in home and community care, medical device complications that arise often lead to increased FC stress and unplanned emergency department (ED) visits. To improve FC experiences, enable safer patient discharge, and reduce after-hours ED visits, this study explores the feasibility of piloting a 24/7 virtual care service (Connected Care Live) with families to provide real-time support by clinicians expert in the use of pediatric home care technologies. This study aims to establish the economic, operational, and technical feasibility of piloting the expansion of an existing nurse-led after-hours virtual care service offered to home and community care providers to FCs of children with newly inserted medical devices after hospital discharge at Toronto's Hospital for Sick Children (SickKids). This exploratory study, conducted from October 2020 to August 2021, used mixed data sources to inform service expansion feasibility. Semistructured interviews were conducted with FCs, nurses, and hospital leadership to assess the risks, benefits, and technical and operational requirements for sustainable and cost-effective future service operations. Time and travel savings were estimated using ED visit data in SickKids' electronic medical records (Epic) with a chief complaint of "medical device problems," after-hours medical device inquiries from clinician emails and voicemails, and existing service operational data. A total of 30 stakeholders were interviewed and voiced the need for the proposed service. Safer and more timely management of medical device complications, improved caregiver and provider experiences, and strengthened partnerships were identified as expected benefits, while service demand, nursing practice, and privacy and security were identified as potential risks. A total of 47 inquiries were recorded over 2 weeks from March 26, 2021, to April 8, 2021, with 51% (24/47) assessed as manageable via service expansion. This study forecasted annual time and travel savings of 558 hours for SickKids and 904 hours and 22,740 km for families. Minimal technical and operational requirements were needed to support service expansion by leveraging an existing platform and clinical staff. Of the 212 ED visits related to "medical device problems" over 6 months from September 1, 2020, to February 28, 2021, enteral feeding tubes accounted for nearly two-thirds (n=137, 64.6%), with 41.6% (57/137) assessed as virtually manageable. Our findings indicate that it is feasible to pilot the expansion of Connected Care Live to FCs of children with newly inserted enteral feeding tubes. This nurse-led virtual caregiver service is a promising tool to promote safe hospital-to-home transitions, improve FC experiences, and reduce after-hours ED visits.

Predictors and Outcomes of Unplanned Emergency Department Visits of ESRD Patients on Maintenance Hemodialysis in a Tertiary Hospital in Davao City

Predictors and Outcomes of Unplanned Emergency Department Visits of ESRD Patients on Maintenance Hemodialysis in a Tertiary Hospital in Davao City

Unplanned emergency department visits after mastectomy in Alberta: Informing a quality improvement initiative.

412 Background: Same day surgery (SDS) for mastectomy increased in Alberta from 1.7% to 73% in 2022, after implementation of a perioperative care pathway in 2016. However, unplanned visits to the emergency department (ED) remained high at 22-27% with &lt;5% requiring readmission. Our study aims to explore factors associated with unplanned ED visits by 1) describing patients with unplanned ED visits within 30 days of mastectomy, and 2) exploring characteristics for unplanned ED visits from the patient perspective. Methods: A survey study was conducted of patients who underwent a mastectomy in Alberta between 07/01/2021 to 06/30/2022 by a general surgeon, and had an unplanned ED visit within 30 days. Patients were identified from the CIHI database; chart review was performed to confirm ED visit details. Patients were excluded if their presentation was unrelated to surgery. Survey questions evaluated 3 domains: medical, socioeconomic, and psychologic, as well as patient-reported experiences of post-operative care. Results: Of 549 patients who underwent mastectomy during the study period, 132 (24%) presented to ED within 30 days. The survey was sent to 87 patients meeting inclusion criteria; 38% responded. Average age was 56. Most patients had no comorbidities (30%) or 2+ (27%), and 85% had prior surgery. The majority (79%) had college education or higher. Treatment included neoadjuvant chemotherapy (24%), sentinel lymph node biopsy (39%), axillary dissection (12%), concurrent reconstruction (24%), and mastectomy alone (27%). Most patients had 2+ drains (70%). Many patients (38%) presented on a weekend, 50% stating the ED was the only choice available at the time. Comparatively, 22% reported being told to go, and 16% felt the ED was the best place for their problem. Patients were seen by an ED physician (89%), nurse (40%) and/or surgeon (28%). Most common reasons for ED visit were infection (38%) and drain concerns (38%). Re-operation and readmission rates were 25% and 19%, respectively. Overall, 84% felt prepared for surgery; only 15% felt uncomfortable with drain management. Patients identified peer support and wound information as areas lacking. While 78% of patients were mostly or very satisfied with surgery, difficulty accessing their surgical team post-operatively was reported as the main flaw. Conclusions: Our study cohort identified infection and drain concerns as the most common reason for unplanned ED visit after mastectomy. Overall, patients were satisfied with education and surgical care, but identified problems with accessing medical/surgical care after discharge. Future initiatives should focus on improved access to outpatient care, and education on post-mastectomy emergencies.

Measuring substance use disorder (SUD) in commercial and Medicaid insured patients with cancer in Washington state.

177 Background: Studies have shown that SUDs not only impact cancer risk, treatment, and survivorship but also increase ED and hospital use. We sought to characterize SUD within Medicaid enrollees diagnosed with cancer in Washington state, hypothesizing thatMedicaid enrollees were more likely to be diagnosed with SUDs than commercial enrollees, and that patients with an SUD experienced higher rates of emergency department (ED) visits or inpatient (IP) stays during initial cancer treatment. Methods: We linked Washington State cancer registry records with claims data from two large commercial insurers and Medicaid. Eligibility criteria included patients under 65 diagnosed with a solid tumor between 2013-2021 who started systemic therapy within 6 months of diagnosis. SUD diagnoses were identified using codes from CMS’s hierarchical condition category for SUD in the 6 months following diagnosis. Chi-square tests were used to compare demographic characteristics of those with and without a SUD diagnosis. Multivariate logistic regressions were used to evaluate the association between SUD and likelihood of at least one ED visit or IP stay, after controlling for payer, sex, race, ethnicity, age, marital status, stage, cancer group, area deprivation index, and diagnosis year. Results: Among the 10,709 patients (6,680 Commercial, 3,718 Medicaid, 311 Multiple) who received systemic therapy, 7.2% had a SUD diagnosis. SUD patients were less likely to be Asian and more likely to be male, living without a partner, diagnosed at a later cancer stage, and living in more deprived areas. Medicaid patients had significantly higher rates of SUD than commercial-insured patients (14.3% vs 3.3%). Overall, 46.6% of cancer patients had an ED visit or IP stay. Patients with SUD had greater use of ED or IP visits than patients without SUD (70.1% and 44.8%, respectively). In the first 6 months of systemic therapy patients with SUD were significantly more likely to visit the ED or be admitted to IP (OR 2.12, 95% CI 1.79 - 2.50) than cancer patients without SUD. Conclusions: More than 1 in 7 Medicaid cancer patients in WA state has an identified SUD. SUD is associated with significant excess risk for ED/IP admissions during treatment. Accurate identification of SUD in patients is necessary prior to strategies aimed at mitigation of unplanned ED visits and hospitalizations during cancer care. Further research is needed on interventions that effectively reduce the risk during treatment.[Table: see text]

Assessing preventable emergency department visits and hospitalizations following implementation of a high-touch program at an academic cancer center.

415 Background: Patients with cancer undergoing treatment are high utilizers of emergency department (ED) services and are at increased risk of hospitalization. A “high-touch” (HT) model of identifying and increasing communication with cancer patients at elevated risk of ED visits was implemented. The goal was to assess whether patients in the HT cohort had a reduced rate of unplanned ED visits and hospitalizations when compared to patients prior to implementation of the model. Methods: In this retrospective study (1/1/2018-4/1/2021), 51 patients on primarily palliative-intent treatment for their cancer were prospectively included in the HT group based on providers’ assessment of their risk of ED visits and malignancy-related complications. This group was compared to a similar cohort (n= 71) pre-implementation of the HT model. Data on baseline characteristics, malignancy type, reason for unplanned ED visits, and patient interaction with the oncology clinic immediately prior to ED visits were obtained, along with end-of-life outcomes including palliative measures. Each ED visit was also categorized as a potentially preventable or non-preventable visit, based on established criteria from Centers for Medicare and Medicaid Services (CMS). Results: While implementation of a HT program did not significantly decrease utilization, the percent of ED visits (p &lt; 0.001) and hospitalizations (p = 0.002) for CMS-preventable reasons was notably higher in the HT cohort. Patients in the HT cohort also reached out to clinic providers significantly more frequently before visiting the ED (p &lt; 0.001). Over half of patients in the HT cohort were seen by a palliative care physician in the inpatient setting within the last 6 months of life. Patients in both groups had similar high rates of dying at home or inpatient hospice versus dying in a hospital setting. Conclusions: Incorporation of a HT model of care in an oncology clinic may promote closer patient interaction with oncology providers prior to emergency department visits, but may come at the cost of increased medical utilization for otherwise CMS-preventable hospitalizations.[Table: see text]

Unplanned Emergency Department Visits Following Revision Total Joint Arthroplasty: Incidences, Risk Factors, and Mortalities

BackgroundThe incidence of unplanned emergency department (ED) visits following revision total joint arthroplasty is an indicator of the quality of postoperative care. The aim of this study was to investigate the incidences, timings, and characteristics of ED visits within 90 days after revision total joint arthroplasty. MethodsA retrospective review of 457 consecutive cases, including 254 revision total hip arthroplasty (rTHA) and 203 revision total knee arthroplasty (rTKA) cases, was conducted. Data regarding patient demographics, timings of the ED encounter, chief complaints, readmissions, and diagnoses indicating reoperation were analyzed. ResultsThe results showed that 41 patients who had rTHA (16.1%) and 14 patients who had rTKA (6.9%) returned to the ED within 90 days postoperatively. The incidence of ED visits was significantly higher in the rTHA group than in the rTKA group (P = .003). The most common surgery-related complications were dislocation among rTHA patients and wound conditions among rTKA patients. Apart from elevated calculated comorbidity scores, peptic ulcer in rTHA patients and cerebral vascular events and chronic obstructive pulmonary disease in rTKA patients might increase chances of unplanned ED visits. Patients who had ED visits showed significantly higher mortality rates than the others in both rTHA and rTKA cohorts (P = .050 and P = .008, respectively). ConclusionsThe ED visits within 90 days are more common after rTHA than after rTKA. Patients in both ED visit groups after rTHA and rTKA demonstrated worse survival. Efforts should be made to improve quality of care to prevent ED visits.

Trimethoprim-Sulfamethoxazole for Pediatric Osteoarticular Infections.

Trimethoprim-sulfamethoxazole (TMP-SMX) is active against most Staphylococcus aureus isolates but is not widely used for treatment of pediatric osteoarticular infections. This was a comparative effectiveness study of hospitalized patients ≤18 years treated with TMP-SMX versus other antibiotic regimens for acute osteoarticular infections between 2016 and 2021 at three hospitals using inverse probability of treatment weighted propensity score analysis. The primary outcome was treatment failure, a composite of unanticipated emergency department (ED) or outpatient visits, hospital readmissions, extension or change of antibiotic therapy due to inadequate clinical response, or death, all within 6 months after completing antibiotics. The secondary outcome was antibiotic-associated adverse events (AEs) within 6 months. The exposed group for the treatment failure analysis included children who received ≥7 days of TMP-SMX and did not experience treatment failure while on another antibiotic. Children receiving at least one dose of TMP-SMX were the exposed group for the AE analysis. 116 patients met eligibility criteria; 26 (22.4%) patients were classified into the TMP-SMX cohort and 90 (77.6%) into the other antibiotics cohort (most commonly clindamycin, vancomycin, and cefazolin). There was no significant difference in treatment failure between TMP-SMX and other antibiotics (43% vs 19%; 95% CI 0.9-10.4). More patients in the TMP-SMX cohort experienced an unplanned ED or outpatient visit (OR 4.8, 95% CI 1.3-17.8). There was no difference in hospital readmission, antibiotic change, or duration extension. Exposure to TMP-SMX was associated with more AEs (41% vs 19%, p=0.012). Treatment with TMP-SMX was not associated with greater clinical failure but was associated with more AEs compared to alternative agents for the treatment of pediatric acute osteoarticular infections.
