Identifying Factors Associated With Mobility Decline Among Hospitalized Older Adults.

The outcome was based on a single nurse-assessed ambulation item from admission to discharge, and improvement and no change were combined, so the measure may miss how mobility changed. Patients who were already completely dependent on admission had no further room to decline, and those who improved or stayed the same were counted as no decline. The study used common nursing assessments for orientation and consciousness, but the paper does not report their reliability or validity. The sample was predominantly White, and only about 1% of patients identified as Hispanic/Latino, so the findings may not generalize to more diverse populations. Because this was a secondary analysis, some variables were not collected or were limited, including detailed socioeconomic status and prior institutionalization. The adjusted model had a c-statistic of 0.624, which means it did not strongly separate patients who declined from those who did not.

No author conflict-of-interest statement is included in the supplied article text. The publication types list NIH extramural research support.

Do not read these results as proof that hearing impairment, non-emergency admission, or longer hospital stays caused mobility decline. The study was a secondary analysis of existing records, and it could not separate these factors from other differences between patients.
