ABSTRACT

OBJECTIVE: Most studies regard orthostatic hypotension (OH) as a causal factor for falls. However, the evidence is lacking for this assumption. We aimed to investigate the relationship between orthostatic hypotension and fall incidents in nursing home residents. METHODS: A total of 249 patients was included in a prospective observational cohort study of nursing home residents. Falls were prospectively registered. Cox proportional hazard modelling and the conditional frailty model were used to analyse the relationship between OH and (recurrent) falling. RESULTS: Among the 249 patients, 450 falls were recorded during follow-up and OH was present in 93 out of 249 patients. No significant associations were found between OH and the first fall incident (Hazard Ratio (HR) 1.01 (95% Confidence Interval (CI) 0.60-1.69) and recurrent falling (HR 1.21 (95%CI 0.65-2.24)). CONCLUSIONS: Although falling and OH were both highly prevalent in nursing home residents, no relationship between OH and falling was found.

ABSTRACT

BACKGROUND: Health-related quality of life (HRQOL) in nursing home residents is generally low. The purpose of this study was to investigate the associations between HRQOL and two clinically relevant outcome measures, all-cause mortality and successful rehabilitation, in a nursing home population. METHODS: In an observational prospective cohort study in a nursing home population, HRQOL was assessed with the RAND-36. A total of 184 patients were included, 159 (86%) completed the RAND-36 and were included in the study. A Cox proportional hazard model was used to investigate the independent association between HRQOL, rehabilitation and mortality with adjustment for confounders. Risk prediction capabilities were assessed with Harrell's C statistics and the proportion of explained variance (R2). RESULTS: The median age (interquartile range) was 79 (75-85) years. The health dimensions vitality (HR 0.88 (95% CI 0.77-0.99)) and mental health (HR 0.86 (95% CI 0.75-0.98)) were inversely associated and role functioningphysical (HR 1.08 (95%CI 1.02-1.15)) was positively associated with mortality. The Harrell's C value and the R2 were ≤ 0.02 and ≤ 0.03 higher in the adjusted models with the dimensions role functioning- physical, mental health or vitality compared with the models without these dimensions. None of the health dimensions or summary scales were related to successful rehabilitation. CONCLUSION: HRQOL was significantly associated with mortality for three dimensions, but partly in opposite directions. Additional value of HRQOL in mortality prediction is very limited. There were no independent associations between HRQOL and successful rehabilitation. Although HRQOL is an important outcome, this study did not provide evidence for an association between HRQOL and successful rehabilitation.

ABSTRACT

PURPOSE OF THE STUDY: Our objectives were to identify the prevalence of orthostatic hypotension (OH) in frail, elderly nursing home residents, and assess its possible association with falling and chances of successful rehabilitation. MATERIALS AND METHODS: A prospective observational cohort study. A total of 290 patients participated in this study, of which 128 were admitted to the rehabilitation department. OH was defined as a drop in systolic blood pressure of >20mmHg and diastolic blood pressure of >10mmHg after postural change within 3min. The analyses regarding falling and successful rehabilitation were only performed in the rehabilitation group. Multivariate binary logistic regression analyses were used to describe risk factors related with falling. Cox proportional hazard modeling was used to investigate the relation between OH and the time to successful rehabilitation. RESULTS: The prevalence of OH in the studied nursing home population was 36.6% (95% CI (confidence interval): 31.1-42.1%). The prevalence varied from 28.6% (95% CI: 16.8-40.4%) in somatic patients, 36.7% (95% CI: 28.4-45.1%) in rehabilitation patients, to 40.6% (95% CI: 31.3-50.0%) in psychogeriatric patients. The association between orthostatic hypotension and previous falling was not significant; Odds ratio 0.66 (95% CI: 0.30-1.48). The Hazard ratio of the relationship between OH and successful rehabilitation was 2.88 (95% CI:1.77-4.69). CONCLUSIONS: OH is highly prevalent in nursing home residents. Surprisingly, patients with OH were found to have a higher chance of successful rehabilitation compared to patients without OH. If confirmed in other studies, these results may change our view of the implications of OH.
