Health-related quality of life at hospital discharge as a predictor for 6-month unplanned readmission and all-cause mortality of acutely admitted older medical patients

To assess whether health-related quality of life (HRQOL) status, using the European Quality of life-5 dimensions (EQ5D), in acutely admitted older medical patients was associated with a combined end-point including first unplanned readmission or death without prior readmission within 6 months. Secondly, to assess if HRQOL was associated with death regardless of previous readmissions.

1328 patients were included, 50% (n = 664) were readmitted (n = 635) or had died without prior readmission (n = 29) within 6 months. In total, 15.2% (n = 202) died within 6 months. In the gender- and age-adjusted analysis, a lower EQ5D index score was associated with a higher hazard ratio (HR) of unplanned readmission or death without prior readmission for all categories of scores below 1 (< 1 to 0.741, < 0.741 to 0.438 and < 0.438 to − 0.40), HR 1.60, 1.93 and 2.02. Likewise, a lower EQ5D score was associated with a higher HR of death, HR 1.72, 2.54 and 3.79. Harrell’s C values were 0.56 and 0.63.

HRQOL measured at discharge may identify acutely admitted older medical patients at especially high risk of readmission or death up to 6 months after discharge. Incorporating assessment of HRQOL should be considered when risk stratifying a heterogeneous population of acutely admitted older medical patients.
