Relationship of physical function and quality of life among persons aging with HIV infection.

ABSTRACT: OBJECTIVE:Physical function impairments are seen among aging, HIV-infected persons on effective antiretroviral therapy (ART). The impact of physical function impairments on health-related quality of life (QoL) during ART is unknown. DESIGN:This was a cross-sectional study including 359 HIV-infected patients, aged 45-65 years, on ART for more than 6 months. METHODS:Patients completed the SF-36 QoL questionnaire, 400-m walk, 5-time chair rise, and grip strength. HIV-associated mortality risk was calculated using the Veterans Aging Cohort Study (VACS) Index. Physical function, physical activity (> 500 versus ? 500 kcal/week), and VACS scores were used to estimate QoL in multivariable linear regression. RESULTS:For every 1 m/s increase in gait speed, we saw an estimated 11.8 [95% confidence interval (CI) 8.4, 15.2] point increase in the physical function scale with smaller differences across all subscales. For every 1 rise/s faster chair rise pace, we saw an estimated 16.0 (95% CI 9.1, 22.9) point increase in the physical function scale with smaller differences across all subscales. SF-36 scores were between 2.8 and 5.7 points higher among more physically active compared to less active patients. A 1 kg increase in grip strength was associated with a 0.2 (95% CI 0.01, 0.3) higher mental health score, but there were no differences in other subscales. VACS scores did not improve the model. CONCLUSIONS:Faster gait speed and chair rise time, and greater physical activity were associated with greater QoL, independent of HIV-related mortality risk. Targeted exercise programs to increase physical activity and improve speed and power should be evaluated as interventions to improve QoL during ART.

Project description:BackgroundOlder patients with acute decompensated heart failure (ADHF) have severely impaired physical function (PF) and quality of life (QOL). However, relationships between impairments in PF and QOL are unknown but are relevant to clinical practice and trial design.MethodsWe assessed 202 consecutive patients hospitalized with ADHF in the multicenter Rehabilitation Therapy in Older Acute HF Patients (REHAB-HF) Trial. PF measures included Short Physical Performance Battery (SPPB) and 6-min walk distance (6MWD). Disease-specific QOL was assessed by the Kansas City Cardiomyopathy Questionnaire (KCCQ). General QOL was assessed by the Short Form-12 (SF-12) and EuroQol-5D-5L. PF was evaluated as a predictor of QOL using stepwise regression adjusted for age, sex, race, and New York Heart Association class.ResultsParticipants were 72 ± 8 years, 54% women, 55% minority race, 52% with reduced ejection fraction, and body mass index 33 ± 9 kg/m2 . Participants had severe impairments in PF (6MWD 185 ± 99 m, SPPB 6.0 ± 2.5 units) and disease-specific QOL (KCCQ Overall Score 41 ± 21 and Physical Score 47 ± 24) and general QOL (SF-12 Physical Score 28 ± 9 and EuroQol Visual Analog Scale 57 ± 23). There were modest, statistically significant correlations between 6MWD and KCCQ Overall, KCCQ Physical Limitation, and SF-12 Physical Scores (r = 0.23, p < 0.001; r = 0.30, p < 0.001; and r = 0.24, p = 0.001, respectively); and between SPPB and KCCQ Physical and SF-12 Physical Scores (r = 0.20, p = 0.004, and r = 0.19, p = 0.007, respectively). Both 6MWD and SPPB were correlated with multiple components of the EuroQol-5D-5L. 6MWD was a significant, weak predictor of KCCQ Overall Score and SF-12 Physical Score (estimate = 0.05 ± 0.01, p < 0.001 and estimate = 0.05 ± 0.02, p = 0.012, respectively). SPPB was a significant, weak predictor of KCCQ Physical Score and SF-12 Physical Score (estimate = 1.37 ± 0.66, p = 0.040 and estimate = 0.54 ± 0.25, p = 0.030, respectively).ConclusionIn older, hospitalized ADHF patients, PF and QOL are both severely impaired but are only modestly related, suggesting that PF and QOL provide complementary information and assessment of both should be considered to fully assess clinically meaningful patient-oriented outcomes.

Project description:Background The REHAB-HF (Rehabilitation Therapy in Older Acute Heart Failure Patients) trial showed that a novel, early, transitional, tailored, progressive, multidomain physical rehabilitation intervention improved physical function and quality of life in older, frail patients hospitalized for acute decompensated heart failure. This analysis examined the relationship between intervention adherence and outcomes. Methods and Results Adherence was defined as percent of sessions attended and percent of sessions attended adjusted for missed sessions for medical reasons. Baseline characteristics were examined to identify predictors of session attendance. Associations of session attendance with change in physical function (Short Physical Performance Battery [primary outcome], 6-minute walk distance, quality of life [Kansas City Cardiomyopathy Questionnaire], depression, and clinical events [landmarked postintervention]) were examined in multivariate analyses. Adherence was 67%±34%, and adherence adjusted for missed sessions for medical reasons was 78%±34%. Independent predictors of higher session attendance were the following: nonsmoking, absence of myocardial infarction history and depression, and higher baseline Short Physical Performance Battery. After adjustment for predictors, adherence was significantly associated with larger increases in Short Physical Performance Battery (parameter estimate: β=0.06[0.03-0.10], P=0.001), 6-minute walk distance (β=1.8[0.2-3.5], P=0.032), and Kansas City Cardiomyopathy Questionnaire score (β=0.62[0.26-0.98], P=0.001), and reduction in depression (β=-0.08[-0.12 to 0.04], P<0.001). Additionally, higher adherence was significantly associated with reduced 6-month all-cause rehospitalization (rate ratio: 0.97 [0.95-0.99], P=0.020), combined all-cause rehospitalization and death (0.97 [0.95-0.99], P=0.017), and all-cause rehospitalization days (0.96 [0.94-0.99], P=0.004) postintervention. Conclusions In older, frail patients with acute decompensated heart failure, higher adherence was significantly associated with improved patient-centered and clinical event outcomes. These data support the efficacy of the comprehensive adherence plan and the subsequent intervention-related benefits observed in REHAB-HF.
