Brief Summary

Introduction Patients living with a chronic disease often have more than one chronic condition, which is referred to as multimorbidity. Multimorbidity is associated with decreased quality of life, functional decline, polypharmacy, and increased healthcare utilization. Patients with multimorbidity often have a high symptom- and treatment burden, and have to attend multiple appointments, often at numerous locations, and comply with complex or even conflicting advice and drug regimens, resulting in an increased risk of depression and low quality of life. In Denmark, general practice is the key organizational setting in terms of offering people with complex multimorbidity integrated, longitudinal, patient-centered care. However, caring for patients with multimorbidity is a complex and time-consuming task and the organization of chronic care in general practice is organized around individual conditions. Research question The objective of the study is to evaluate the effectiveness of a complex intervention consisting of a prolonged consultation and a strengthened cross-sectoral collaboration for patients with complex multimorbidity listed in participating practices on the patients' health-related quality of life, health and use of health-services. Methods Design: A pragmatic, adaptive, cluster-randomized, non-blinded, parallel-group trial conducted in general practice in all regions in Denmark evaluating a complex intervention.

Outcome Measures

Primary Outcomes (1)

  • Needs-based quality of life measured with MMQ1 - PROM

    The primary outcome is needs-based quality of life measured with MMQ1 (unpublished at present). The outcome consist of six unidimensional domains; physical capacity, worries, limitations in daily activities, social life, self-image and economy with a scale from 0-3 per item (sum scores differ due to differences in the number f items) We expect our intervention to be able to affect the three domains; worries, limitations in daily life and social life. We will consider a clinically significant improvement in at least one domain as a success.

Intervention

EXPERIMENTAL
Other: Complex intervention to enhance care for patients with multimorbidity in general practice consisting of an extended overview consultation and supporting elements

Control

NO INTERVENTION

Interventions

The intervention consists of 1) an extended overview consultation lasting 30-45 minutes in general practice, 2) access to cross-sectoral video conferences with secondary care specialists and 3) an instruction material for GPs on how to organize the intervention and 4) an adaptive toolbox to support elements in the intervention (not yet developed)
