    Accidental Falls and Risk of Mortality among Older Adults on Chronic Peritoneal Dialysis
    (Amer Soc Nephrology, 2014) Farragher, Janine; Chiu, Ernest; Ulutas, Ozkan; Tomlinson, George; Cook, Wendy L.; Jassal, Sarbjit V.
    Background and objectives More than 40% of elderly hemodialysis patients experience one or more accidental falls within a 1-year period. Such falls are associated with higher mortality. The objectives of this study were to assess whether falls are also common in elderly patients established on peritoneal dialysis and evaluate if patients with falls have a higher risk of mortality than patients who do not experience a fall. Design, setting, participants, & measurements Using a prospective cohort study design, patients ages years on chronic peritoneal dialysis from April 2002 to April 2003 at the University Health Network were recruited. Patients were followed biweekly, and falls occurring within the first 15 months were recorded. Outcome data were collected until death, study end (July 31, 2012), transplantation, or transfer to another dialysis center. Results Seventy-four of seventy-six potential patients were recruited, assessed at baseline, and followed biweekly for falls; 40 of 74 (54%) peritoneal dialysis patients experienced 89 falls (adjusted mean fall rate, 1.7 falls per patient-year; 95% confidence interval, 1.0 to 2.7). Patients with falls were more likely to have had previous falls, be more recently initiated onto dialysis, be men, be older, and have higher comorbidity. Twenty-eight patients died during the follow-up period. After adjustment for known risk factors, each successive fall was associated with a 1.62-fold higher mortality (hazard ratio, 1.62; 95% confidence interval, 1.29 to 2.02; P<0.001). Conclusions Accidental falls are common in the peritoneal dialysis population and often go unrecognized. Falls were associated with higher mortality risk. Because fall interventions are effective in other populations, screening peritoneal dialysis patients for falls may be a simple measure of clinical importance.

    EQUIVALENT FALL RISK IN ELDERLY PATIENTS ON HEMODIALYSIS AND PERITONEAL DIALYSIS
    (Multimed Inc, 2016) Farragher, Janine; Rajan, Tasleem; Chiu, Ernest; Ulutas, Ozkan; Tomlinson, George; Cook, Wendy L.; Jassal, Sarbjit V.
    Background: Accidental falls are common in the hemodialysis (HD) population. The high fall rate has been attributed to a combination of aging, kidney disease-related morbidity, and HD treatment-related hazards. We hypothesized that patients maintained on peritoneal dialysis (PD) would have fewer falls than those on chronic HD. The objective of this study was to compare the falls risk between cohorts of elderly patients maintained on HD and PD, using prospective data from a large academic dialysis facility. Methods: Patients aged 65 years or over on chronic in-hospital HD and PD at the University Health Network were recruited. Patients were followed biweekly, and falls occurring within the first year recorded. Fall risk between the 2 groups was compared using both crude and adjusted Poisson lognormal random effects modeling. Results: Out of 258 potential patients, 236 were recruited, assessed at baseline, and followed biweekly for falls. Of 74 PD patients, 40 (54%) experienced 86 falls while 76 out of 162 (47%) HD patients experienced a total of 305 falls (crude fall rate 1.25 vs 1.60 respectively, odds ratio [OR] falls in PD patients 0.78, 95% confidence interval [CI] 0.61 - 0.92, p = 0.04). After adjustment for differences in comorbidity, number of medications, and other demographic differences, PD patients were no less likely to experience accidental falls than HD patients (OR 1.63, 95% CI 0.88 - 3.04, p = 0.1). Conclusions: We conclude that accidental falls are equally common in the PD population and the HD population. These data argue against post-HD hypotension as the sole contributor to the high fall risk in the dialysis population.

    FUNCTIONAL DISABILITY IN OLDER ADULTS MAINTAINED ON PERITONEAL DIALYSIS THERAPY
    (Sage Publications Inc, 2016) Ulutas, Ozkan; Farragher, Janine; Chiu, Ernest; Cook, Wendy L.; Jassal, Sarbjit V.
    Background: Older in-center hemodialysis patients have a high burden of functional disability. However, little is known about patients on home chronic peritoneal dialysis (PD). As patients opting for home dialysis are expected to play a greater role in their own dialysis care, we hypothesized that a relatively low number of PD patients would require help with basic self-care tasks (ADL) and instrumental activities of daily living (IADL). Methods: We used a cross-sectional study design to measure the proportion of patients aged 65 years and older undergoing outpatient PD who needed help with day-to-day activities. Patients living in nursing homes were excluded from the study. Functional dependence in ADL and IADL tasks were measured by the Barthel and Lawton Scales. Physical performance measures used included the timed up-and-go (TUG) test, chair stands and Folstein mini-mental score (MMSE). Results: A total of 74 of 76 (97%) eligible PD patients participated. Patients had a mean age of 76.2 +/- 7.5 years. Thirty-six percent had impaired MMSE scores, 69% were unable to stand from a chair without the use of their arms and 51% had abnormal TUG scores. Only 8 patients (11%) were fully independent for both ADL and IADL activities. Dependence in one or more ADL activity was reported by 64% of participants, while 89% reported dependence in one or more IADL. Conclusions: Impaired physical and functional performance is common in older patients maintained on PD. Collaborative geriatric-renal programs may be beneficial within the dialysis community.
