Statins and Selective Serotonin Reuptake Inhibitors are Associated with Longer Survival in Nursing Home Residents.

BACKGROUND: Statins and selective serotonin reuptake inhibitors (SSRIs) have beneficial effects on health outcomes in the general population. Their effect on survival in debilitated nursing home residents is unknown. OBJECTIVES: To assess the relationships between statins, SSRIs, and survival of nursing home residents. METHODS: Baseline patient characteristics, including chronic medications, were recorded. The association of 5-year survival with different variables was analyzed. A sub-group analysis of survival was performed according to baseline treatment with statins and/or SSRIs. RESULTS: The study comprised 993 residents from 6 nursing homes. Of them, 285 were males (29%), 750 (75%) were fully dependent, and 243 (25%) were mobile demented. Mean age was 85 ± 7.6 years (range 65-108). After 5 years follow-up, the mortality rate was 81%. Analysis by sub-groups showed longer survival among older adults treated with only statins (hazard ratio [HR] for death 0.68, 95% confidence intervals [95%CI] 0.49-0.94) or only SSRIs (HR 0.6, 95%CI 0.45-0.81), with the longest survival among those taking both statins and SSRIs (HR 0.41, 95%CI 0.25-0.67) and shortest among residents not taking statins or SSRIs (P < 0.001). The survival benefit remained significant after adjusting for age and after conducting a multivariate analysis adjusted for sex, functional status, body mass index, mini-mental state examination, feeding status, arrhythmia, diabetes mellitus, chronic kidney disease, and hemato-oncological diagnosis. CONCLUSIONS: Treatment with statins and/or SSRIs at baseline was associated with longer survival in debilitated nursing home residents and should not be deprived from these patients, if medically indicated.

Does Polypharmacy in Nursing Homes Affect Long-Term Mortality?

OBJECTIVES: To investigate the association between polypharmacy and mortality in nursing home (NH) residents. DESIGN: Prospective observational cohort study. SETTINGS: Six NHs in central Israel. PARTICIPANTS: Mobile with dementia and fully dependent residents (N = 764; n = 558 (73%) fully dependent, n = 206 (27%) mobile residents with dementia requiring institutional care; mean age 82.2 ± 5.9). MEASUREMENTS: Two-year mortality and its association with number of drugs that individual residents were taking at baseline, controlled for multiple confounders. RESULTS: At baseline, 268 residents were taking five or fewer drugs per day, 202 were taking six or seven, and 294 were taking eight or more. In the multivariate analysis, the likelihood of dying within 2 years in the group taking six or seven drugs per day (odds ratio (OR = 0.95, 95% CI = 0.63-1.43) and in those taking eight or more (OR = 1.20, 95% CI = 0.78-1.84) was similar to that of those taking five or fewer. Variables at baseline independently associated with greater mortality were male sex (OR = 1.75, 95% CI = 1.24-2.46), older age (OR = 1.07, 95% CI = 1.04-1.10), higher Charlson Comorbidity Index (OR = 1.17, 95% CI = 1.04-1.30), and taking anticoagulant (OR = 1.78, 95% CI = 1.01-3.13) or antihyperglycemic medication (OR = 1.69, 95% CI = 1.12-2.53). Variables at baseline independently associated with lower mortality were higher body mass index (OR = 0.99, 95% CI = 0.93-0.99) and taking lipid-lowering medication (OR = 0.54, 95% CI = 0.36-0.80) and selective serotonin reuptake inhibitors or serotonin-norepinephrine reuptake inhibitors (OR = 0.52, 95% CI = 0.37-0.75). CONCLUSION: Polypharmacy, defined quantitatively according to number of drugs, was not associated with mortality in these NH residents.

Perioperative urinary retention, short-term functional outcome and mortality rates of elderly hip fracture patients.

AIM: Perioperative urinary retention (POUR) is common among hip fracture patients. The aim of the present study was to compare the prevalence, risk factors, functional outcomes and survival rates of patients with and without POUR. METHODS: This was a retrospective chart review study that was carried out in an orthogeriatric hip fracture unit. A total of 639 consecutive hip fracture patients who had hip surgery followed by a standard rehabilitation course participated in the study. Post-void residual volume (PVRV), Functional Independence Measure (FIM) scores (total and motor FIM, FIM gain) and mortality rates (90 and 365 days, end of follow up) were measured. RESULTS: A total of 328 patients (51.3%) suffered from POUR. Diabetes (OR 1.55, 95% CI 1.04-2.31), urinary infection (OR 3.25, 95% CI 2.16-4.90) and delirium (OR 1.66. 95% CI 1.09-2.52) emerged as the best predictors for POUR. Functional gains were slightly better in patients without POUR (P = 0.037 and P = 0.023, for discharge motor and total FIM gain, respectively). There were no differences in FIM gains at discharge in male patients, whether with or without POUR. However, female patients without POUR showed significantly better motor and total FIM gains on discharge (P = 0.003 and P = 0.003, respectively), compared with females with POUR. In multiple linear regression analyses, POUR in female (but not male) patients was predictive for adverse motor FIM gain (beta = -0.089, P = 0.046). In Cox regression analysis, urinary retention was not associated with mortality rates. CONCLUSIONS: POUR is highly prevalent in elderly hip fracture patients. It adversely affects the functional outcome of female patients, but is not associated with increased mortality rates.

Rates, variability, and associated factors of polypharmacy in nursing home patients.

OBJECTIVES: To determine the rate and variability of polypharmacy in nursing home (NH) residents and investigate its relationship to age, sex, functional status, length of stay, and comorbidities. METHODS: We conducted a cross sectional, multicenter study that included six nursing homes. Demographic, clinical characteristics, Charlson comorbidity index (CCI), the number and classes of chronic medications, rate of polypharmacy >5 drugs (per day) and polypharmacy >7 drugs (per day) were recorded. RESULTS: Nine hundred and ninety-three residents were included; 750 (75.5%) fully dependent residents and 243 (24.5%) mobile demented residents requiring institutional care. The mean age was 85.04±7.55 (65-108) years. The mean rates of polypharmacy >5 drugs and polypharmacy >7 drugs were 42.6% and 18.6%, respectively. Differences in polypharmacy >5 drugs and polypharmacy >7 drugs were observed in NHs 24.7%-56% and 4.9%-30.4%, respectively (P<0.001). Mean number of chronic drugs per resident was 5.14±2.60 from 3.81±2.24 to 5.95±2.73 (P<0.001). No differences in polypharmacy were found between sex and fully dependent versus mobile demented residents. The most common medications taken were for gastrointestinal, neurological, and cardiovascular disorders. Regression analysis revealed four independent variables for polypharmacy >5 drugs: groups aged 75-84 and >85 relative to 65-74, odds ratio (OR) 0.46 (95% confidence interval [CI] 0.27-0.78) P=0.004, OR 0.35 (95% confidence interval 0.19-0.53), respectively, P<0.001; length of stay >2 years, OR 0.51 (95% CI 0.36-0.73) P<0.001; CCI, OR 1.58 (95% CI 1.42-1.75) P<0.001; and feeding tube versus normal feeding, OR 0.27 (95% CI 0.12-0.60) P=0.001. CONCLUSION: Rates of polypharmacy in NHs are high with significant variability. Variability rates of polypharmacy, distinct residents' characteristics, and excessive use of certain drug groups may indicate that a decrease in medication is potentially feasible.
