What is the clinical evidence from this study?

Study design: Cohort. Population: Adults (mean age 74.5 years, 54% female) hospitalized in medical and surgical wards with physical function evaluated by CAS, 30s-STS, or HGS (n=5062). Intervention: Physical function assessment using Cumulated Ambulation Score (CAS), 30-second Sit-To-Stand test (30s-STS), and Handgrip Strength (HGS) vs. Normal physical function according to Danish age- and sex-specific reference values. Primary outcome: All-cause 1-year mortality (HR 1.98 for reduced CAS; HR 3.57 for reduced 30s-STS; HR 2.06 for reduced HGS, 95% CI CAS 1.71–2.29; 30s-STS 2.21–5.78; HGS 1.66–2.56, p=<0.001).

What does this research mean for the field?

Reduced physical function, as assessed by CAS, 30s-STS, or HGS, is associated with a markedly increased 1-year mortality in hospitalized older adults. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

The study aims to determine how physical function assessment can predict 1-year mortality in older hospitalized patients.

Assessment of physical function of hospitalized older patients in routine clinical practice predicts 1-year mortality; A cohort study of 5,062 medical and surgical patients

Q: What are the key findings of this study?

Reduced physical function assessed by CAS, 30s-STS, or HGS was associated with a markedly increased 1-year mortality with HRs of 1.98, 3.57, and 2.06 respectively in hospitalized older adults.

PICO estructurado

Does reduced physical function predict increased 1-year mortality in hospitalized older medical and surgical patients?

Población

5,062 adult medical and surgical hospitalized patients evaluated by physical or occupational therapists at an acute-care community hospital, mean age 74.5 years, 54.4% women.

Intervención

Reduced physical function as assessed by the Cumulated Ambulation Score (CAS), Handgrip strength (HGS), or 30s-Sit-To-Stand test (30s-STS).

Comparador

Normal physical function according to Danish sex- and age-decade reference values.

Resultado

All-cause mortality at 30-day, 90-day, and 1-year follow-up.hard clinical

Reduced physical function, as assessed by simple tests like CAS, HGS, and 30s-STS, is a strong predictor of 1-year mortality in hospitalized older patients.

Resultado numérico

Estimación del efecto: HR 1.98 for reduced CAS; HR 3.57 for reduced 30s-STS; HR 2.06 for reduced HGS (95% CI CAS 1.71–2.29; 30s-STS 2.21–5.78; HGS 1.66–2.56)

valor p: p=<0.001

Limitaciones

Observational design precludes causal inference between physical function and mortality.
Incomplete data collection for HGS (51% assessed) with selection bias as frailest patients less likely assessed.
Over 90% of patients showed reduced 30s-STS performance limiting its discriminative utility.
No adjustment for other mortality predictors such as frailty, nutritional, or cognitive status beyond multimorbidity index.
Study conducted at a single acute-care hospital in Denmark limiting generalizability.

Resumen

In older medical and surgical hospitalised patients with reduced physical function (CAS, 30s-STS or HGS) 1-year mortality was markedly increased. This simple test battery is rapid and low-cost and can easily be implemented in other hospitals, acute care facilities, and across sectors.

Kristensen et al. (Sat,) realizaron un estudio de cohortes en adultos (edad media 74.5 años, 54% mujeres) hospitalizados en servicios médicos y quirúrgicos, con función física evaluada mediante el CAS, 30s-STS o HGS (n=5,062). La evaluación de la función física utilizando la puntuación de ambulación acumulada (CAS), la prueba de levantarse y sentarse en 30 segundos (30s-STS) y la fuerza de agarre manual (HGS) frente a la función física normal de acuerdo con los valores de referencia daneses específicos por edad y sexo fue evaluada sobre la mortalidad a 1 año por todas las causas (HR 1.98 para CAS reducido; HR 3.57 para 30s-STS reducido; HR 2.06 para HGS reducido, IC del 95% CAS 1.71–2.29; 30s-STS 2.21–5.78; HGS 1.66–2.56, p=<0.001). La función física reducida evaluada por CAS, 30s-STS o HGS se asoció con una mortalidad a 1 año marcadamente aumentada, con HR de 1.98, 3.57 y 2.06 respectivamente en adultos mayores hospitalizados.
