ObjectivesMultimorbidity challenges healthcare systems. In Germany, coordination of healthcare for older multimorbid patients remains unstructured.This study aims to identify key themes in the healthcare of these patients and the inter-relationships between them.DesignFramework analysis of six cases based on 1-year data of primary and secondary care, patient-answered questionnaires and video material.SettingSouthern Germany.ParticipantsSix multimorbid older patients participating in a randomised controlled trial that compared usual care with a local, collaborative, stepped and personalised care management approach for older people with chronic diseases (LoChro-trial). The LoChro care intervention involved a care manager who assisted participants in self-management. The primary outcome was a composite of functional health and depressive symptoms at 12 and 18 months. The LoChro-intervention had no effect on the primary outcome.Primary outcome measureKey themes in the healthcare of older patients with multimorbidity and the inter-relationships between them.MethodsOne-year data included diagnoses, treatment plans, examinations, assessments and discharge reports. Patient perspectives were assessed using the Patient Assessment of Chronic Illness Care. In three cases, videos of the LoChro intervention showed patients describing their health needs. These data were evaluated by three doctors and public health researchers. Using framework analysis, recurring themes influencing the healthcare situation of multimorbid older patients and their inter-relationships were identified.ResultsParticipants had an average age of 77, with 13 diagnoses, taking eight medications regularly. The five key themes describing the healthcare situation of these multimorbid patients were as follows:insufficient coordination,overuseandunderuse of medical care,doctorandpatient roles. Each theme covered three to four subcategories. The most significant inter-relationships between these themes were a lack of coordination leading to overuse and underuse of medical care. These were characterised by redundant inpatient stays, potential prescribing omissions and missed examinations. Deficiencies in vaccinations and secondary prevention were also demonstrated.ConclusionCoordination of care for multimorbid older patients in Germany is still deficient. Future healthcare arrangements should be explored with the participation of physicians and patients.Trial registration numberLoChro trial: DRKS00013904.
