Exercise Intervention and Hospital-Associated Disability: A Nonrandomized Controlled Clinical Trial.

Importance: Inpatient exercise interventions may prevent, at least partly, hospital-associated disability (HAD) in older adults, but whether they also confer clinical benefits in the months following discharge is unclear. Objective: To examine the association of exercise and health education with HAD incidence in hospitalized older adults receiving acute hospital care at discharge and 3 months later. Design, Setting, and Participants: This single-center open-label, nonrandomized controlled clinical trial included patients aged 75 years or older seen at an acute care for elders unit at a tertiary public hospital in Madrid, Spain, from May 1, 2018, to June 30, 2022. Interventions: Patients were allocated to an intervention or control group. Both groups received usual care, but the intervention group also performed a supervised multicomponent exercise program (daily strength, balance, and walking exercises along with inspiratory muscle training) during hospitalization and received health education on how to exercise at home and telephone counseling during follow-up. Main Outcomes and Measures: The primary outcome was HAD incidence (determined by the Katz Index of Independence in Activities of Daily Living [hereafter, Katz Index]) at discharge and after 3 months compared with baseline (ie, 2 weeks before admission). Secondary outcomes included HAD incidence determined by the Barthel Index for Activities of Daily Living, ambulatory capacity decline at discharge and follow-up, changes in physical performance at discharge, and incidence of falls, readmissions, and mortality during the follow-up period. Results: The study included 260 patients (134 women [51.5%]; mean [SD] age, 87.4 [4.9] years [range, 75-105 years]; median hospital length of stay, 7 days [IQR, 5-10 days]), of whom 130 received the intervention and 130 were in the control group. Differences in HAD incidence did not reach statistical significance at discharge (odds ratio [OR], 0.62; 95% CI, 0.37-1.05; P = .08) or follow-up (OR, 0.65; 95% CI, 0.36-1.17; P = .15) when using the Katz Index. A lower HAD incidence was observed in the intervention group at discharge (OR, 0.47; 95% CI, 0.27-0.81; P = .01) and at follow-up (OR, 0.36; 95% CI, 0.20-0.66; P = .001) when using the Barthel Index for Activities of Daily Living. The intervention was also associated with a lesser decline in ambulatory capacity (OR, 0.55; 95% CI, 0.32-0.96; P = .03) and improved physical performance at discharge (Cohen d, 0.39; 95% CI, 0.12-0.65; P = .004). No significant associations were observed for readmissions, falls, or mortality. Conclusions and Relevance: In this nonrandomized controlled clinical trial, an exercise and health education intervention was not significantly associated with reduced HAD incidence when measured by the Katz Index. However, the benefits found for several secondary outcomes might support the implementation of in-hospital exercise programs for older patients.

"Inspiratory muscle weakness in acutely hospitalized patients 75 years and over": a secondary analysis of a randomized controlled trial on the effectiveness of multicomponent exercise and inspiratory muscle training.

PURPOSE: The impact of hospitalization for acute illness on inspiratory muscle strength in oldest-old patients is largely unknown, as are the potential benefits of exercise and inspiratory muscle training (IMT) during in-hospital stay. DESIGN AND METHODS: This was a sub-study of a randomized clinical trial that evaluated the efficiency of a multicomponent exercise program in preventing hospitalization-associated disability. Patients were randomized into control (CG) and intervention (IG) groups. The intervention included two daily sessions of supervised walking, squat, balance, and IMT. Baseline and discharge maximal inspiratory pressure (MIP) and inspiratory muscle weakness (IMW) were determined. The effect of the intervention on inspiratory muscle strength was assessed by analyzing (1) the differences between groups in baseline and discharge MIP and IMW, (2) the association, patient by patient, between baseline and discharge MIP, and the improvement index (MIP discharge/baseline) in patients with or without IMW. RESULTS: In total, 174 patients were assessed (mean age of 87), 57 in CG and 117 in IG. Baseline MIP was lower than predicted in both sexes (women 29.7 vs 44.3; men 36.7 vs 62.5 cmH2O, P < 0.001, baseline vs predicted, respectively). More than 65% of patients showed IMW at admission. In women in IG, the mean MIP was higher at discharge than at admission (P = 0.003) and was the only variable that reached expected reference levels at discharge (Measured MIP 39.2 vs predicted MIP 45 cmH2O, P = 0.883). Patients with IMW on admission showed a statistically significant improvement in MIP after the intervention. CONCLUSION: IMW is very prevalent in oldest-old hospitalized with acute illness. Patients might benefit from a multicomponent exercise program including IMT, even during short-stay hospitalization. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov; No.: NTC03604640. May 3, 2018.

[Functional recovery at discharge and at three months after a multicomponent physical exercise intervention in elderly subjects hospitalized in an Acute Geriatric Unit]. / Recuperación funcional al alta y a tres meses tras una intervención multicomponente de ejercicio físico en ancianos hospitalizados en una unidad de agudos de geriatría.

INTRODUCTION: Hospitalization in the elderly, even in short stays, is associated with functional impairment. Once the acute illness is reversed, the evolution of this hospital-generated impairment can be variable, and a year after hospitalization more than half of the elderly patients remain impaired. This impairment is associated with a higher risk of institutionalization, of mortality at discharge and of 30-day mortality. Previous studies have shown how interdisciplinary physical exercise programs can improve functionality at discharge and decrease mortality rate, hospital stay and institutionalization. STUDY DESIGN AND OBJECTIVES: In the Acute Geriatric Unit of the Gregorio Marañon University hospital a randomized controlled trial was carried out to assess the effectiveness of an exercise and health education program to prevent functional decline during hospitalization and at three months after discharge in elderly subjects aged 74 years or older. Patients were excluded if at least one of the following exclusion criteria was met: baseline Barthel Index (15-days prior hospitalization) below 20, severe cognitive impairment or inability to walk. The intervention consisted on a physical exercise program (that included squats, balance, gait stimulation, elastic bands, and inspiratory muscle training) and health education program. The control group received usual care.
