Optimal care at the end of life (OPAL): study protocol of a prospective interventional mixed-methods study with pretest-posttest-design in a primary health care setting considering the view of general practitioners, relatives of deceased patients and health care stakeholders

BACKGROUND: At the end of life, about 85–90% of patients can be treated within primary palliative care (PC) provided by general practitioners (GPs). In Germany, there is no structured approach for the provision of PC by GPs including a systematic as well as timely identification of patients who might benefit from PC, yet. The project “Optimal care at the end of life” (OPAL) focusses on an improvement of primary PC for patients with both oncological and non-oncological chronic progressive diseases in their last phase of life provided by GPs and health care services. METHODS: OPAL will take place in Hameln-Pyrmont, a rural region in Lower Saxony, Germany. Target groups are (a) GPs, (b) relatives of deceased patients and (c) health care providers. The study follows a three-phase approach in a mixed-methods and pre-post design. In phase I (baseline, t(0)) we explore the usual practice of providing PC for patients with chronic progressive diseases by GPs and the collaboration with other health care providers. In phase II (intervention) the Supportive and Palliative Care Indicators Tool (SPICT) for the timely identification of patients who might benefit from PC will be implemented and tested in general practices. Furthermore, a public campaign will be started to inform stakeholders, to connect health care providers and to train change agents. In phase III (follow-up, t(1)) we investigate the potential effect of the intervention to evaluate differences in the provision of PC by GPs and to convey factors for the implementation of SPICT in general practices. DISCUSSION: The project OPAL is the first study to implement the SPICT-DE regionwide in general practices in Germany. The project OPAL may contribute to an overall optimisation of primary PC for patients in Germany by reducing GPs’ uncertainty in initiating PC, by consolidating their skills and competencies in identifying patients who might benefit from PC, and by improving the cooperation between GPs and different health care stakeholders. TRIAL REGISTRATION: The study was retrospectively registered at the German Clinical Trials Register (Deutsches Register Klinischer Studien; trial registration number: DRKS00015108; date of registration: 22th of January 2019).
