Prevalence, characteristics, and impact on health outcomes of frailty in elderly outpatients with diabetes: A cross-sectional study.

The aims of this study were to determine the prevalence of frailty and its relationship with health outcomes in elderly outpatients attending a Diabetes Specialist Clinic. This study was a cross-sectional study. A total of 168 elderly patients (aged 65 years and above) attending the Diabetes Specialist Clinic of a Three-A hospital of Sichuan province were recruited from January 2021 to February 2021, and follow-up was conducted 1 year after day of screening. Baseline characteristics of patients were collected and frail status were assessed at recruitment. The longitudinal outcomes included hospitalization, fall, mortality, emergency visit, and clinic visit. The presence of frailty was determined by the 5-item FRAIL scale, which ranges from 0 to 5 and are categorized as frail (3-5), prefrail (1-2), and robust (0). A phone questionnaire was carried out to obtain health outcomes. Logistic regression analyses was used to evaluate adverse health outcomes at 1 year follow-up. Of the 168 outpatients, 28.0% was robust, 49.4% was prefrail, and 22.6% was frail. Frailty (both prefrail and frail status) was more prevalent in those patients, which were 75 years old and above (57.0%; P < .001), insulin dependent (45.6%; P = .008), and those had diabetic complications (43.8%; P = .005), previous admission (68.6%; P = .016), and co-morbidities (36.4%; P = .001). In the following year after recruitment, 19.1% of robust patients were hospitalized, while the proportion was 45.8% for prefrail patients and 65.8% for frail patients. Prefrail (OR [odds ratio] = 2.35, 95% confidence interval (CI) 1.63-2.88; P = .028) and frail (OR = 4.63, 95% CI 2.52-5.81; P = .005) patients were more likely to be hospitalized. Frail (OR = 3.37, 95% CI 2.68-4.04; P < .001) patients were more inclined to fall while prefrail patients (OR = 1.03, 95% CI 0.82-1.56; P = .371) were not. Moreover, prefrail (OR = 3.37, 95% CI 2.31-5.72; P = .017) and frail (OR = 4.29, 95% CI 3.16-5.54; P = .006) patients were more likely to return to the clinic. There is a high incidence of frailty among elderly patients attending a Diabetes Specialist Clinic. Frailty is a predictor of hospitalization, fall, and clinic visits within 1 year.
