Abstract
INTRODUCTION: Violet Program (ViP) was developed to address the current home palliative service gap for individuals with life limiting non-cancer conditions residing in the Eastern part of Singapore. While its basic principles and processes have been planned and implemented, how ViP works, for whom and in what circumstances are not yet well understood. Therefore, we propose for a realist evaluation (RE) - a theory-based evaluation, to address the current knowledge gaps. Evaluation findings may guide, support further development and broader uptake of ViP. METHODS AND ANALYSIS: This study will be conducted in three phases: 1. development of initial program theory (IPT), 2. testing of programme theory, and 3. refinement of IPT. First, IPT will be elicited through review of programme documents, scoping review of reviews and in-depth interviews with stakeholders involved in the conceptualization of ViP. Then, a convergent mixed method study will be conducted to assess contexts (C), mechanisms (M) and outcomes (O) to test the IPT through interviews with stakeholders, surveys and analysis of program and administrative databases. Based on findings gathered and through consultation with respective stakeholders, IPT will be refined to highlight what works (outcomes), how (mechanisms) and for whom under what conditions (contexts).
