Functional Ability, Psychological Factors, and Rehabilitation Outcomes After Elective Total Hip Replacement.

PMID 37072927WHAT IT FOUND
Older adults in rehab after hip replacement improved their function but did not regain their pre-surgery level.
Higher positive affect predicted shorter hospital stays, but did not predict better functional ability at discharge.
Key findings
01Participants showed significant functional improvement during rehabilitation but remained below their pre-surgery functional ability level at discharge.
02Higher positive affect predicted a shorter length of stay in rehabilitation, adding significant predictive value beyond physical factors.
03Positive affect was not correlated with functional ability at admission, discharge, or the amount of functional improvement.

What it does not show
The study had a very small sample size of 30 participants recruited from a single center, limiting generalizability. Pre-surgery functional scores were based on retrospective reports, which are less reliable than prospective measurements. The study only included patients in inpatient rehabilitation, excluding those who receive home-based rehab after surgery. Inter-rater reliability for the functional scores was not tested, although they were recorded by a skilled multidisciplinary team.

The easy way to misread this
Do not assume that improving a patient's mood will improve their physical function. While positive affect predicted a shorter hospital stay, it was not associated with better functional ability or greater improvement in mobility and self-care.
