Clinical Outcomes In Older Patients Research Articles

Clinical Outcomes in Older Patients Aged over 75 Years Who Underwent Early Surgical Treatment for Pyogenic Vertebral Osteomyelitis.

Older patients with pyogenic vertebral osteomyelitis (PVO) usually have more medical comorbidities compared with younger patients, and present with advanced infections from different causative organisms. To aid surgical decision-making, we compared surgical outcomes of older patients with PVO to those who underwent nonoperative treatment. We identified the risk factors for adverse post-operative outcomes, and analyzed the clinical risks from further spinal instrumentation. This retrospective comparative study included 439 patients aged ≥75 years with PVO. Multivariable analysis was performed to compare treatment outcomes among three groups: 194, 130, and 115 patients in the non-operative, non-instrumented, and instrumented groups, respectively. The risk factors for adverse outcomes after surgical treatment were evaluated using a logistic regression model, and the estimates of the multivariable models were internally validated using bootstrap samples. Recurrence and mortality of these patients were closely associated with neurologic deficits, and increased surgical invasiveness, resulting from additional spinal instrumentation, did not increase the risk of recurrence or mortality. We propose that surgical treatment for these patients should focus on improving neurologic deficits through immediate and sufficient removal of abscesses. Spinal instrumentation can be performed if indicated, within reasonable clinical risk.

Association of the lateral wall integrity with clinical outcomes in older patients with intertrochanteric hip fractures treated with the proximal femoral nail anti-rotation-Asia.

The purpose of this study is to assess the role of the lateral wall in post-operative clinical outcomes in patients with intertrochanteric fractures treated with the proximal femoral nail anti-rotation-Asia (PFNA-II). A cohort of 466 patients (OTA type 31A1 or A2) was divided into two groups: one was intact lateral wall group, and the other was fractured lateral wall group. Radiographic outcomes were measured by using the loss of neck-shaft angle (NSA), femoral neck shortening (FNS), and offset shortening (OS). Functional outcomes were assessed by using the Harris score and SF-36 Physical Component Summary (SF-36 PCS). Post-operative complications were recorded. The fractured lateral wall group had a greater loss of NSA (mean [SD], fractured group (8.7°) [2.7°] vs intact group (4.8°) [2.8°]; mean difference, 3.3° [95% CI 2.9 to 3.8]; P < 0.001) compared with the intact lateral wall group. Similar results were found for FNS and OS. The fractured lateral wall group had a worse Harris scores at the threemonth follow-up (mean [SD] score, fractured group (66.6) [5.2] points vs intact group (71.3) [5.8] points; mean difference, - 3.3 points [95% CI - 3.9 to - 2.7]; P < 0.001) compared with the intact lateral wall group. Similar results were observed for Harris scores at the threeand 12-month follow-ups and SF-36 PCS at the three, six and 12-month follow-ups. The fractured lateral wall group had a higher risk of post-operative complications compared with the intact lateral wall group. Among older patients with intertrochanteric fractures, the fractured lateral wall was associated with worse clinical outcomes compared with the intact lateral wall. Clinicians should pay attention to the lateral wall integrity in patients with intertrochanteric fractures treated with the PFNA-II.

Impact of physical frailty on the clinical outcomes of older patients hospitalized for pneumonia.

This study aimed to assess the association between physical frailty and clinical outcomes among older patients hospitalized for pneumonia. This study examined 852 consecutive patients hospitalized for pneumonia between October 2018 and September 2020. Patients who were <65 years old, scheduled for admission, did not receive inpatient rehabilitation, or died during admission were excluded. A short physical performance battery (SPPB) test was performed by physical therapists upon discharge. The primary outcome measure was a composite endpoint of readmission or mortality due to any cause within 6 months of discharge. In total, 521 patients (median age, 80 years; interquartile range, 74-86 years) were included in the analyses, and were divided into the following two groups: robust group with SPPB scores >9 (n=150), and physical frailty group with SPPB scores ≤9 (n=371). Of these, 346 (66.4%) patients were men; and the median SPPB score was 6 (interquartile range, 1-10). During the median follow-up period of 53 days (interquartile range, 4-180 days), 92 (17.6%) patients were readmitted and 25 (4.8%) patients died. Patients with physical frailty were at an increased risk for the primary endpoint (hazard ratio, 2.21; 95% confidence interval, 1.44-3.41; P < 0.001); the risk remained significant after adjusting for multiple variables (adjusted hazard ratio, 1.70; 95% confidence interval, 1.05-2.74; P=0.028). Among older patients with pneumonia, physical frailty status at discharge was an independent risk factor for readmission and mortality within 6 months after initial discharge.

433 SAME SPECIALITY, DIFFERENT REALITY?

Abstract Introduction The United Kingdom and Spain run government-funded social and health care services, free for the user at the point of delivery. Acute Geriatric Units (AGU) carrying out Comprehensive Geriatric Assessments improve the clinical outcomes of older patients. Little is known about the similarities and differences between countries, and how these may impact on clinical outcomes. Methods Prospective observational study of consecutive patients admitted to AGU of 2 hospitals in the UK and 4 hospitals in Spain between the 1st to the 30th of October 2019 and from the 1st to the 29th of February 2020. We followed up the patients for a 90 day period. Conclusions Frailty, multimorbidity and polypharmacy were prevalent in both cohorts. English patients were younger, with shorter hospital stay, mortality and use of antipsychotic medication but higher readmission rates. Involvement from Allied health care professionals was higher in UK hospitals.

Nutritional risk assessed by the Malnutrition Universal Screening Tool as a predictor of frailty in acutely hospitalised older patients: An observational study.

Frailty and malnutrition are overlapping geriatric syndromes and leads to poor clinical outcomes in older patients. This study determined whether Malnutrition Universal Screening Tool (MUST) can predict frailty in older hospitalised patients. This prospective study recruited 243 patients ≥65 years in a tertiary-teaching hospital in Australia. Frailty assessment was performed by use of the Edmonton-Frail-Scale (EFS), while malnutrition-risk was determined by use of the MUST. Patients with an EFS score >8 were classified as frail, while patients with a MUST score of 1 as at moderate malnutritionrisk and ≥2 as at high malnutrition-risk. Multivariable logistic regression determined whether malnutrition-risk predicts frailty after adjustment for various co-variates. The mean (SD) age was 83.9 (6.5) years) and 126 (51.9%) were females. One-hundred and forty-nine (61.3%) patients were classified as frail, while 66 (27.2%) were found to be at high malnutrition-risk according to the MUST. Frail patients were more likely to be older with a higher Charlson-index and on polypharmacy than non-frail patients. Patients who were at high malnutrition- risk were more likely to be living alone and on vitamin D supplementation than those at low malnutritionrisk. Patients who were at a high malnutrition-risk but not those who were at moderate malnutrition-risk, were more likely to be deemed frail (aOR 2.6, 95% CI 1.2-5.5, p=0.015) when compared to those who were at low malnutrition-risk. Only patients who were classified as at high malnutrition-risk according to the MUST are more likely to be deemed frail.

Sarcopenia index as a predictor of clinical outcomes in older patients undergoing transcatheter aortic valve replacement.

Sarcopenia is a prevalent condition in elderly patients and has been associated with adverse outcomes following transcatheter aortic valve replacement (TAVR). The present study aimed to determine the predictive value of serum creatinine-cystatin C ratio, that is, "Sarcopenia Index" (SI) as a surrogate marker of sarcopenia, and investigate its association with clinical outcomes after TAVR. We conducted a retrospective observational study of patients undergoing TAVR between January, 2016 and December, 2018 at Hospital Italiano de Buenos Aires, Argentina. Patients were excluded if <65-years old, presented previous surgical aortic valve replacement, severe chronic kidney disease, or hemodialysis requirement. The SI was obtained at baseline before TAVR. All-cause mortality and/or readmissions for congestive heart failure (CHF) were defined as the primary endpoint. In total 100 patients met inclusion criteria for the purpose of the study. Sarcopenia Index was significantly correlated with Timed Up and Go (r=-0.272, p=.010) and Gait Speed (r=-0.278, p=.005). During follow-up, 5/100 patients died within 30 days and a total of 10/100 patients died at 1-year follow-up. Moreover, survival curves were significantly worse (Log-rank test=p=.02) and CHF readmissions were more prevalent in the lowest SI tertile (Log-rank test=p=.01). In multivariate Cox regression analysis, we identified low SI (cutoff ≤66) as an independent predictor of long-term adverse outcomes (HR=4.01, 95% CI=1.31-12.27, p=.015) at 1-year follow-up. Sarcopenia Index, surrogate for the degree of skeletal muscle mass (SMM), could be used as a predictor of adverse outcomes in patients undergoing TAVR.

Activity of daily living upon admission is an independent predictor of in-hospital mortality in older patients with community-acquired pneumonia

BackgroundOlder patients hospitalized with community-acquired pneumonia (CAP) are at high risk for short-term mortality. Activity of daily living (ADL) is associated with clinical outcomes in older patients. We aimed to investigate the prognostic value of ADL upon admission on the in-hospital mortality in older patients with CAP.MethodsWe conducted a retrospective cohort study involving patients aged ≥65 years admitted to Beijing Chao-Yang hospital due to CAP between June 2012 and June 2020. ADL evaluation upon admission was performed by Barthel Index (BI). Data from all patients were extracted from the electronic medical records.ResultsFour thousand eight hundred eighty patients were included, 131 patients (2.7%) died during their hospitalization. Median BI in the Deceased group was 45 (20–65), Deceased group had lower BI scores than Survivors group (p < 0.001). Low BI (< 60) was more frequent in patients who died in the hospital than in patients discharged alive (69.5% vs. 13%, p < 0.001). In-hospital mortality was higher among patients with worse ADL upon admission (BI< 60) compared to those BI≥60 (12.6% vs. 0.9%). The worse ADL upon admission (BI< 60) was associated with an increase in the risk of death during CAP hospitalization, worse ADL upon admission (BI< 60) showed an odds ratio (OR) for in-hospital mortality of 7.53 (95%CI: 2.77–20.48; P < 0.01). This association remained significant after adjustment for age, comorbid conditions, respiratory failure, pathogens and laboratory findings (OR, 3.74; 95%CI, 2.37–5.91; P < 0.01). Receiver operating characteristic (ROC) curve revealed that BI upon admission is a predictor related to in-hospital mortality in elderly patients, the area under the ROC curve of BI in predicting in-hospital mortality was 0.81 (with 95% confidence interval: 0.78–0.85). The predictive value of ADL upon admission was better than age in our study population.ConclusionActivity of daily living upon admission is an independent predictor of in-hospital mortality in older patients with community-acquired pneumonia.

Body mass index affects postoperative daily activities of older patients after gastrectomy.

This study aimed to examine the impact of preoperative body mass index (BMI) on postoperative activities of daily living (ADL) and clinical outcomes in older patients who underwent curative gastrectomy. This was a retrospective observational study using a nationwide inpatient database in Japan. The study included 1769 patients with gastric cancer, aged ≥ 65years old, who underwent gastrectomy. BMI was defined as per the World Health Organization classifications for Asian populations. Primary outcome was ADL at discharge, assessed by Barthel index. Secondary outcomes included postoperative complications and length of hospital stay. Patients analyzed included 890 (50.3%) aged 65-74years, 745 (42.1%) aged 75-84years, and 134 (7.6%) aged ≥ 85years; 71.5% were male. According to BMI classification, 11.9% patients were considered underweight (< 18.5kg/m2), 46.7% were in the standard range (18.5to< 23kg/m2), 34.1% were classified as overweight (23-27.5kg/m2), and 7.3% were in the obese group (≥ 27.5kg/m2). In multivariate analysis, a significant association was observed between BMI and Barthel index scores (underweight group: standardized coefficient, - 0.040; compared with standard group; p = 0.013), postoperative complication (obese group: odds ratio, 1.562; compared with standard group; p = 0.034), and length of hospital stay (obese group: standardized coefficient, 0.047; compared with standard group; p = 0.019). Perioperative management with a focus on BMI is important in older patients undergoing elective curative gastrectomy.

Clinicopathological characteristics and prognostic marker of triple-negative breast cancer in older women

Triple-negative breast cancer (TNBC) lacks an effective treatment target and is usually treated with chemotherapy. Treatment of older patients with TNBC, however, should be decided carefully because of the side effects of chemotherapy in this population. Some forms of TNBC are associated with a favorable prognosis and do not require chemotherapy. To optimize the treatment of older patients with TNBC, it is important to know the clinicopathological characteristics and a prognostic marker. In this study, classic clinicopathological factors, immunohistochemical characteristics (androgen receptor [AR], cytokeratin 5/6 [CK5/6], epidermal growth factor receptor), tumor-infiltrating lymphocytes (TILs), and the clinical outcome based on the status of each biomarker were compared among a consecutive series of female patients with TNBC aged ≥75 years (n = 75) and among those aged 55–64 years matched for the pathological stage (n = 47) who underwent surgery without neoadjuvant therapy. TNBC with special histology (particularly apocrine carcinoma, pleomorphic invasive lobular carcinoma, and metaplastic carcinoma) was more frequent in the older group than in the younger group (35/75, 57% versus 11/47, 23%, P = 0.010). The AR positivity rate was higher in older patients than in younger patients, whereas TILs and CK5/6 exhibited the opposite results. In multivariate analyses, AR positivity was an independent predictor of a favorable outcome in older patients (lower recurrence rate), whereas the high level of TILs was favorable in younger patients (lower recurrence and mortality rates). AR positivity or apocrine morphology was frequent and predicts a favorable clinical outcome in older patients with TNBC, suggesting the importance of AR examination in this population.

Treatment Compliance and Clinical Outcomes in Older Patients with Cervical Cancer Treated with Radio(chemo)therapy—A Retrospective Analysis

To evaluate the treatment patterns, compliance and survival outcomes in older patients with cervical cancer. Data on demographic, tumour and treatment characteristics, toxicities and outcomes were analysed in women with cervical cancer of age ≥ 65 years treated between March 2010 and November 2015 with radical radio(chemo)therapy (RT ± CT) and high-dose-rate (HDR) intracavitary brachytherapy (ICBT). A total of 111 patients with median age 66 years (interquartile range [IQR], 65–70) were included. Majority (82%) had locally advanced cervical cancer, and 45% (50 patients) had comorbidities. Cisplatin-based concurrent chemotherapy was received by 54 (48.6%) patients with a median of 4 (IQR, 3–5) cycles. Radical RT ± CT was received by 105 (94.6%) patients of whom 98% (103 patients) received HDR ICBT with a median of 4 applications (IQR, 3–4). The median overall treatment time (OTT) was 60 days (IQR, 49–69). The median follow-up duration was 45 months (IQR, 22–71). The 3-year overall survival (OS), disease-free survival (DFS), local control (LC) and distant metastasis control rates (DMCR) were 71.7% [95% CI, 71.6–71.8], 65.6% [95% CI, 65.5–65.7], 93% [95% CI, 92.9–93.1] and 86.5% [95% CI, 86.4–86.6], respectively. The OS and DFS were significantly better with the addition of concurrent chemotherapy compared to RT alone (3-year OS 85.5% [95% CI, 85.4–85.6] vs 58.1% [95% CI, 57.9–58.2], p = 0.01; 3-year DFS 79.3% [95% CI, 79.2–79.3] vs 53.8% [95% CI, 53.7–53.9], p = 0.002). Older patients with cervical cancer tolerate radical radio(chemo)therapy and better outcomes were observed in patients who received concurrent chemoradiation.

An increase in neutrophil-to-lymphocyte ratio predicts poor functional outcomes in older patients with acute ischemic stroke: a retrospective study.

The neutrophil-to-lymphocyte ratio has emerged as a predictor of functional outcome in stroke patients. However, less is known about the value of neutrophil to lymphocyte ratio in older patients. This clinical study evaluated whether the neutrophil-to-lymphocyte ratio is associated with stroke severity and early clinical outcomes in older patients with acute ischemic stroke. This observational study included acute ischemic stroke patients aged 80 years or older. The patients were divided into three groups, and information was collected, including demographic, clinical and laboratory data. The neutrophil associations to lymphocyte ratio with stroke severity and early clinical outcomes were assessed with logistic regression. Overall, 356 older patients were enrolled in this study, with a median age of 85.0 (82.0-88.0). Split by tertiles of neutrophil-to-lymphocyte ratio, 118 patients were in the bottom tertile (<2.17), 118 patients were in the middle tertile (2.17-3.36), and 120 patients were in the top tertile (>3.36). After multivariable analysis, patients in the highest tertile were likely to have moderate to severe stroke on admission (OR 4.87, 95% CI, 1.93-12.30, P = 0.001), higher risks of primary unfavorable outcome (OR 2.70, 95% CI, 1.09-6.69, P = 0.032) and secondary unfavorable outcome (OR 2.00, 95% CI, 1.00-4.00, P = 0.050) compared to the lowest tertile. Our finding demonstrated that the neutrophil-to-lymphocyte ratio is an independent predictor of stroke severity and early clinical outcomes in older patients with acute ischemic stroke.

Characteristics and Outcomes of Hip Fracture Patients Hospitalized in an Orthogeriatric Unit Versus an Orthopedic Department: A Retrospective Cohort Study

Introduction:Hip fractures are a significant health risk in older adults and a major cause of morbidity, functional decline and mortality. Our aim was to compare clinical outcomes of older patients hospitalized in an ortho-geriatric (OG) unit to those hospitalized in an orthopedic department (OD) for surgical treatment of a hip fracture.Methods:A retrospective cohort study of hip fractured patients hospitalized between 2015-2016 in a single tertiary university-affiliated medical center. Included were patients aged 65 and older who had undergone hip fracture surgery and were admitted to either a geriatric or orthopedic ward.Results:441 patients met the inclusion criteria (195 in the OG unit, 246 in the OD); 257 were transferred to an affiliated geriatric center hospital (107 from the OG unit and 127 from the OD) for rehabilitation. Patients in the OG unit were older, more cognitively and functionally impaired and with more comorbidities. The 1-year mortality rate was significantly lower in the OD group (OR 0.32, CI 95% 0.19-0.53, p < 0.001), however, after propensity matching, the 30-day and 1 year mortality rates were similar in both groups. No difference was found in the rehabilitation length of stay between the groups. The functional independence measure improvement was similar in both groups, with a non-significant trend toward better functional improvement among OG unit patients.Conclusions:Despite the higher complexity of patients, worse baseline functional capacity in the OG unit, improvement after rehabilitation was similar in both groups. These results demonstrate the advantages of the OG unit in treating and stabilizing frail older adults, thus maximizing their chances for a successful recovery after hip fractures.Level of Evidence:Level IV

Effectiveness of a Geriatric Emergency Medicine Unit for the Management of Neurocognitive Disorders in Older Patients: Results of the MUPACog Study

Introduction: The prevalence of neurocognitive disorders (NCDs) increases with age and is associated with cognitive impairment. Older patients with NCD admitted to the emergency department (ED) are readmitted after discharge to home more often than those without NCD. Comprehensive geriatric assessment (CGA) is effective for improving clinical outcomes in older patients; however, the usefulness of CGA for older patients with NCD admitted to the ED has not been investigated. The main objective of our study is to assess the effectiveness of a geriatric emergency medicine unit (GEMU) for elderly patients with NCD admitted to the ED. Methods: This historical cohort study included patients aged 75 years and older with NCD admitted to the ED of Limoges University Hospital in France over a 4-year period. We compared patients treated in our hospital’s GEMU, the MUPA unit (exposed group), and patients who received standard care by emergency physicians (control group). The primary end point was the incidence of 30-day readmissions. Results: The study included 801 patients admitted to the ED between January 1, 2015, and December 31, 2018 (400 in the exposed group). Of those, 72.5% were female, and the mean age was 87 ± 5 years. After adjusting for confounding factors, the 30-day readmission rate was significantly associated with the MUPA unit intervention. Conclusion: CGA in a GEMU improved health outcomes in elderly patients with NCD in the ED. We recommend that all EDs include a geriatric team, such as the MUPA unit, to treat all patients with NCD admitted to the ED.

Disease- and Treatment-related Complications in Older Patients With Inflammatory Bowel Diseases: Comparison of Adult-onset vs Elderly-onset Disease.

The incidence and prevalence of inflammatory bowel diseases (IBD) in older adults are rising. There is a limited comparative assessment of risk of disease- and treatment-related complications in older patients (older than 60 years) with adult-onset (age at disease onset, 18-59 years; AO-IBD) vs elderly-onset IBD (age at disease onset, older than 60 years; EO-IBD). We compared clinical outcomes in older patients with IBD with AO-IBD vs EO-IBD. We conducted a retrospective cohort study comparing risk of disease-related complications (IBD-related surgery, hospitalization, treatment escalation, clinical flare, or disease complication) and treatment-related complications (serious infection, malignancy, or death) in older patients with AO-IBD vs EO-IBD through Cox proportional hazard analysis, adjusting for age at cohort entry, disease phenotype, disease duration, prior surgery and/or hospitalization, medication use, disease activity at cohort entry, and comorbidities. We included 356 older patients with IBD (AO-IBD, 191 patients, 67 ± 5 y at cohort entry; EO-IBD, 165 patients, 72 ± 8 y at cohort entry). No significant differences were observed in the risk of disease-related complications in older patients with prevalent vs incident IBD (adjusted hazard ratio [aHR], 0.85; 95% CI, 0.58-1.25), although risk of IBD-related surgery was lower in older patients with prevalent IBD (aHR, 0.47; 95% CI, 0.25-0.89). Older patients with prevalent IBD were significantly less likely to experience treatment-related complications (aHR, 0.58; 95% CI, 0.39-0.87). Patients with AO-IBD have lower risk of treatment-related complications as they age compared with patients with EO-IBD, without a significant difference in risk of disease-related complications.

Sarcopenia Index as a Predictor of Clinical Outcomes in Older Patients with Coronary Artery Disease.

To demonstrate the association of the serum creatinine/serum cystatin C ratio (sarcopenia index, SI) with clinical outcomes including cardiovascular and bleeding risk in older patients who underwent percutaneous coronary intervention (PCI), we analyzed a multicenter nation-wide pooled registry. A total of 1086 older patients (65 years or older) who underwent PCI with second-generation drug-eluting stents (DES) were enrolled. The total population was divided into quartiles according to the SI, stratified by sex. The primary clinical outcomes were major adverse cardiovascular events (MACE, all-cause death, myocardial infarction and target lesion revascularization) and thrombolysis in myocardial infarction major and minor bleeding during a 3-year follow-up period. In the total population, MACE occurred within 3 years in 154 (14.2%) patients. The lowest SI quartile group (Q1) had a significantly higher 3-year MACE rate (Q1 vs. Q2–4; 23.1% vs. 11.2%, p < 0.001), while bleeding event rates were similar between the groups (Q1 vs. Q2–4; 2.6% vs. 2.2%, p = 0.656). The Cox proportional hazard model showed that lower SI is an independent predictor for MACE events (HR 2.23, 95% CI 1.62–3.07, p < 0.001). The SI, a surrogate for the degree of muscle mass, is associated with cardiovascular and non-cardiovascular death, but not with bleeding in older patients who underwent PCI.

High neutrophil-to-lymphocyte ratio associated with progression to critical illness in older patients with COVID-19: a multicenter retrospective study.

This retrospective cohort study aimed to investigate the correlation of the neutrophil-to-lymphocyte ratio (NLR) with critical illness in older patients with COVID-19, and evaluate the prognostic power of the NLR at admission. We enrolled 232 patients with COVID-19, aged ≥60 y, in Zhejiang province from January 17 to March 3, 2020. Primary outcomes were evaluated until April 13. Cox regression was performed for prognostic factors. Twenty-nine (12.5%) patients progressed to critical illness. Age, shortness of breath, comorbidities including hypertension, heart disease, and chronic obstructive pulmonary disease, higher NLR, lower albumin levels, and multiple mottling and ground-glass opacity were associated with progression. In the multivariate analysis, older age (hazard ratio [HR] 1.121, confidence interval [CI] 1.070-1.174, P<0.001), heart disease (HR 2.587, CI 1.156-5.787, P=0.021), higher NLR (HR 1.136, CI 1.094-1.180, P < 0.001), and multiple mottling and ground-glass opacity (HR 4.518, CI 1.906-10.712, P<0.001) remained critical illness predictors. The NLR was independently associated with progression to critical illness; the relationship was significant and graded (HR: 1.16 per unit; 95% CI: 1.10-1.22; P for trend < 0.001). Therefore, NLR can be adopted as a prognostic tool to assist healthcare providers predict the clinical outcomes of older patients suffering from COVID-19.

Chronicity of Uncorrected Hyponatremia and Clinical Outcomes in Older Patients Undergoing Hip Fracture Repair.

Background: Chronic hyponatremia is a risk factor for hip fracture but remains uncorrected in most patients. This study evaluated if preoperative chronicity of uncorrected hyponatremia influences outcomes after hip fracture repair.Materials and Methods: Evaluated were older patients hospitalized for hip fracture repair between 2007 and 2012 with plasma sodium measured at admission and ≥1 preadmission outpatient measurement. Patients were classified as being normonatremic (NN; plasma sodium 135–145 mmol/L), chronic prolonged hyponatremia (CPH; ≥2 consecutive plasma sodium values <135 mmol/L over >90 days), or recent hyponatremia (one plasma sodium <135 mmol/L within 30 days before admission with previously normal plasma sodium). Length of hospital stay, in-hospital death, post-operative complications, 30-day readmission, and long-term mortality were the evaluated outcomes. Multivariable Cox regression was used to evaluate the association of hyponatremia status with outcomes.Results: Among 1,571 eligible patients, 76.7% were NN, 14% had CPH, and 9.1% had RH. Compared with NN patients, CHN patients were older and had more prior heart failure, alcoholism, and anticonvulsant drug use. In multivariable analyses, neither CPH or RH was associated with hospital length of stay, in-hospital or 30-day death, or 30-day readmission, while RH was associated with post-operative sepsis [adjusted odds ratio (aOR) 1.84, 95% CI: 1.01–3.35). Only CPH was independently associated with long-term all-cause death (OR 1.53, 95% CI: 1.12–2.09).Conclusions: Hyponatremia affects nearly 25% of patients undergoing hip fracture repair. Preoperative chronic untreated hyponatremia is associated with increased post-operative mortality following surgical repair of a hip fracture in older patients. Future studies should evaluate if correction of hyponatremia could decrease long-term mortality after hip fracture repair.

Hospital-Acquired Functional Decline and Clinical Outcomes in Older Patients Undergoing Transcatheter Aortic Valve Implantation.

This study aimed to assess the relationship between hospital-acquired functional decline and the risk of mid-term all-cause death in older patients undergoing transcatheter aortic valve implantation (TAVI).Methods and Results:In total, 463 patients (mean age 85 years, interquartile range [IQR]: 82, 88) undergoing elective TAVI at Sakakibara Heart Institute between 2010 and 2018, who were followed up for 3 years, were enrolled in the study. Hospital-acquired functional decline after TAVI, which was defined by at least a 1-point decrease on the Short Physical Performance Battery before discharge compared to the preoperative score, was assessed. A total of 113 patients (24.4%) showed hospital-acquired functional decline after TAVI, and 50 (11.3%) patients died over a mean follow-up period of 1.9±0.8 years. Kaplan-Meier survival curves indicated that hospital-acquired functional decline was significantly associated with all-cause mortality (log-rank test, P=0.001). On multivariate Cox regression analysis, hospital-acquired functional decline was associated with a higher risk of all-cause mortality (OR 2.108, 95% CI 1.119-3.968, P=0.021) independent of sex, body mass index, advanced chronic kidney disease, and preoperative frailty, as assessed by the modified essential frail toolkit. Hospital-acquired functional decline is associated with mid-term all-cause mortality in older patients following TAVI. Trajectory of functional status is a vital sign, and it is useful for risk stratification in older patients following TAVI.

Clinical Outcomes in Older Patients Undergoing Percutaneous Coronary Intervention for Non-ST-Elevation Acute Coronary Syndromes

Distinguishing the subgroup of older, comorbid patients presenting with non-ST-elevation acute coronary syndromes (NSTEACS) who will benefit from percutaneous coronary intervention (PCI) remains challenging. Identifying risk factors for major adverse cardiac or cerebrovascular events (MACCE) post PCI may help define this cohort. The objective of this study was to describe contemporary outcomes of older patients with NSTEACS undergoing PCI and identify pre-procedural risk factors for MACCE. We retrospectively reviewed data for 1,875 patients aged ≥80 years entered in the Victorian Cardiac Outcomes Registry (VCOR) who underwent PCI for NSTEACS between 1 January 2013 and 31 December 2017. MACCE was a composite outcome comprising 30-day mortality, myocardial infarction, stroke, major bleeding, target lesion revascularisation or target vessel revascularisation; in-hospital cardiogenic shock or stent thrombosis; and new requirement for dialysis. Patient demographic data and pre-procedural comorbidities were compared between the groups with and without a MACCE. The rate of MACCE at 30 days was 8.0% (n=150). Thirty-day (30-day) mortality was 3.0% (n=57). Pre-procedural left ventricular ejection fraction (LVEF)<45% (OR 2.32; 95% CI 1.47-3.68; p<0.001) and eGFR≤30 mL/min/1.73m2 or renal replacement therapy (OR 2.10; 95% CI 1.27-3.46; p<0.01) were independent predictors of a MACCE. Older patients presenting with NSTEACS who have left ventricular systolic dysfunction or renal impairment are at increased risk of MACCE post PCI. Randomised studies are required to determine if invasive management remains beneficial for these patents compared with medical therapy.

Clinical outcomes of older patients with AML receiving hypomethylating agents: a large population-based study in the United States

AbstractThe hypomethylating agents (HMAs) azacitidine and decitabine have been the de facto standard of care for patients with acute myeloid leukemia (AML) who are unfit for intensive therapy. Using the Surveillance, Epidemiology, and End Results-Medicare linked database, we identified 2263 older adults (age ≥66 years) diagnosed with AML during 2005-2015 who received a first-line HMA; 1154 (51%) received azacitidine, and 1109 (49%) received decitabine. Median survival from diagnosis was 7.1 and 8.2 months (P < .01) for azacitidine- and decitabine-treated patients, respectively. Mortality risk was higher with azacitidine vs decitabine (hazard ratio [HR], 1.11; 95% confidence interval [CI], 1.01-1.21; P = .02). The findings were similar when evaluating only patients completing ≥4 cycles (42% of patients treated with either azacitidine or decitabine). These findings lost significance when evaluating those completing a standard 7-day schedule of azacitidine (34%) vs 5-day schedule for decitabine (66%) (HR, 0.95; 95% CI, 0.83-1.08; P = .43). Red blood cell (RBC) transfusion independence (TI) was achieved in one-third of patients with no difference between the 2 HMAs. In conclusion, the majority of older AML patients did not receive the minimum of 4 cycles of HMA often needed to elicit clinical benefit. We observed no clinically meaningful differences between azacitidine- and decitabine-treated patients in their achievement of RBC TI or survival.
