MRC Methodology Grant: Iterative VoI Routine databases Literature DEVELOP DECISION MODEL BASED ON CURRENT INFORMATION ONLY Expert Opinion Is Vit D cost-effective? How certain are we? Routine data (SIMPLIFIED) Demographics Secondary care prescriptions Dialysis attendance HRQoL Mortality Secondary end points NLSV data (SIMPLIFIED+) A&E contacts Non-renal related OP, IP Primary care contacts & prescriptions Social services received Out of pocket expenses Lost productivity Interim analysis UPDATE DECISION MODEL Is it worth continuing with NLSV data collection?
