Abstract
Aim
To investigate if health-related quality of life (HRQOL) is associated with physical function in older adults with or at risk of mobility disability after hospital discharge.
Findings
Better physical function (SPPB) was significantly associated with a higher level of physical HRQOL (SF-36 subscales physical functioning, role physical, bodily pain and general health).
Message
The positive associations between physical function and physical HRQOL might indicate that the exercise interventions aiming to improve physical function might also improve physical HRQOL in this group of older adults.

Purpose
To optimise the treatment for older adults after hospitalisation, thorough health status information is needed. Therefore, we aimed to investigate the associations between health-related quality of life (HRQOL) and physical function in older adults with or at risk of mobility disability after hospital discharge.
Methods
This cross-sectional study recruited 89 home-dwelling older people while inpatients within medical wards at a general hospital in Oslo, Norway. HRQOL [the Medical Outcome Study 36-Item Short-Form Health Survey (SF-36)] and physical function [the Short Physical Performance Battery (SPPB)] were measured a median of 49 [interquartile range (IQR) 26–116] days after discharge. Simple linear regression analyses were conducted, and multivariable regression models were fitted.
Results
The mean age of the patients was 78.3 years; 43 (48.9 %) were females. Multivariable regressions showed positive associations between SPPB and the physical subscales {physical functioning [B (95% CI) 4.51 (2.35–6.68)], role physical [B (95% CI) 5.21 (2.75–7.67)], bodily pain [B (95% CI) 3.40 (0.73–6.10)] and general health [B (95% CI) 3.12 (1.13–5.12)]}. Univariable regressions showed no significant associations between SPPB and the mental subscales {vitality [B (95% CI) 1.54 (− 0.10–3.18)], social functioning [B (95% CI) 2.34 (− 0.28–4.96)], role emotional [B (95% CI) 1.28 (− 0.96–3.52)] and mental health [B (95% CI) 1.00 (− 0.37–2.36)]}.
Conclusion
The results reinforce that physical function and physical HRQOL are strongly linked, and interventions improving physical function might improve physical HRQOL. However, this hypothesis would have to be tested in a randomised controlled trial.
