Last Year of Life Study Cologne (LYOL-C): protocol for a cross-sectional mixed methods study to examine care trajectories and transitions in the last year of life until death

Introduction

The last year of life constitutes a particularly vulnerable phase for patients, involving nearly all health and social care structures. Yet, little scientific evidence is available that provides insight into the trajectories including the number and types of care setting transitions, transitions into palliative care and the dying phase. Only few studies have focused on difficulties associated with having to move between health and social care settings in the last year of life, although patients face a significant risk of adverse events. The Last Year of Life Study Cologne (LYOL-C) aims to fill this gap.

Methods and analysis

LYOL-C is a mixed-methods study composed of four steps: (1) Claims data collected by the statutory health insurance funds of deceased persons will be analysed with regard to patient care trajectories, health service transitions and costs in the last year of life. (2) Patient trajectories and transitions in healthcare will additionally be reconstructed by analysing the retrospective accounts of bereaved relatives (n=400) using a culturally adapted version of the Views of Informal Carers—Evaluation of Services Short Form questionnaire and the Patient Assessment of Care for Chronic Conditions Short Form questionnaire adapted for relatives. (3) Qualitative interviews with bereaved relatives (n=40–60) will provide in-depth insight into reasons for transitions and effects on patients' quality of life. (4) Focus groups (n=3–5) with Healthcare Professionals will be conducted to discuss challenges associated with transitions in the last year of life.

Ethics and dissemination

Ethical approval has been obtained from the Ethics Commission of the Faculty of Medicine of Cologne University (#17–188). Results will be submitted for publication in peer-reviewed journals and presented at national and international conferences.

Trial registration number

The study is registered in the German Clinical Trials Register (DRKS00011925) and in the Health Services Research Database (VfD_CoRe-Net_17_003806).
