The prognostic signature of health-related quality of life in older patients admitted to the emergency department: a 6-month follow-up study.

Background: The management of older and multimorbid patients with complex care requires a personalised and comprehensive approach. The main diagnosis is often registered as the cause of hospitalisation, yet poor health-related quality of life (HRQoL) as well as multimorbidity may represent the underlying cause and markedly influence prognosis.

Aims: To analyse the association of HRQoL and clinical prognosis over time as assessed by a Comprehensive Geriatric Assessment (CGA)-based Multidimensional Prognostic Index (MPI) in older patients admitted to the emergency department (ED).

Methods: We used data from the prospective MPI-HOPE (Influence of the MPI on the Hospitalisation of Older Patients admitted to the Emergency department) study. Data from 165 patients (≥ 75 years) admitted to the ED of the University Hospital of Cologne, Germany, between Oct 2017 and Jan 2018 were included. Clinical prognosis was calculated by the MPI and HRQoL by the EQ5D-5L. Follow-up interviews assessed HRQoL up to 6 months after discharge.

Results: Most patients were multimorbid and presented with several geriatric syndromes. At admission, HRQoL was highest in patients with the best clinical prognosis. The MPI showed a negative correlation with the EQ-Index at admission (r(86) = - 0.50, p < 0.0001) and follow-up assessments after 3 and 6 months (r(86) = - 0.55 and r(86) = - 0.47, p < 0.0001).

Discussion: Our results suggest that patients' self-perceived HRQoL in the ED is related to functional health status and clinical prognosis.

Conclusion: The MPI as a multidimensional snapshot provides information on clinical health indicators and informs about subjective HRQoL, thereby helping in identifying patients who would benefit from a specific treatment within the frame of a patient-centered, value-based care strategy geriatric treatment.
