WHAT IT FOUND

In older orthopaedic inpatients, ISarcoPRM sarcopenia was more common among patients whose walking independence worsened during hospitalization.

AWGS2019 sarcopenia was not.

Key findings

01In the adjusted analysis, sarcopenia defined by the ISarcoPRM algorithm was significantly associated with worsened gait independence on discharge (odds ratio 3.94, 95% confidence interval 1.51 to 10.25, p = 0.005).

02In the adjusted analysis, sarcopenia defined by the AWGS2019 algorithm was not significantly associated with worsened gait independence on discharge (odds ratio 1.08, 95% confidence interval 0.42 to 2.80, p = 0.88).

03Sarcopenia was present in 56.2% of patients by ISarcoPRM and 36.6% by AWGS2019, and 26.8% had worsened gait independence on discharge.

What it does not show

The study is observational, so it cannot show that sarcopenia caused worsened walking independence. The methods section says 812 patients were included, but the analysis included 153; the supplied text does not explain this difference. Only 26.8% had worsened gait, and the confidence interval for the ISarcoPRM association was wide (1.51 to 10.25), so the estimate is imprecise. Patients had to be able to walk with supervision or independently before admission and neurological complications were excluded, so the findings may not apply to more independent patients or those with neurological problems. The authors suggest postoperative oedema may have affected the AWGS2019 body composition measure, which could influence the comparison between algorithms.

Declared interests

The authors declared no conflicts of interest.

The easy way to misread this

Do not conclude that identifying sarcopenia by ISarcoPRM will predict or improve walking independence. This was an observational association in hospitalised older orthopaedic patients, and no intervention was tested.
