A Fair Test of the IAPT LTC/MUS Pathfinders IAPT data GBU analysis? Professor Simon Jones Ms Eleni Theodorou
Objectives: To : • Share our outline analysis plan • What data to we have for the evaluation? • What is Good, Bad, or Ugly?
Subgroups of interest • Question: How can we identify people in the • various groups? • Data sources • Fields and Codes • GBU analysis
Data Analysis for LTC & MUS service users For each of the subgroups • Socio-Demographics profile • Common mental health problems and other comorbidities • describe duration and type of intervention • outcomes of intervention • explore and quantify relations between independent/predictor variables • Question: Are there any other analysis which you would find useful?
Outcome scales • Personal Health Questionnaire (PHQ9) • Generalised Anxiety Disorder (GAD) score • Work and Social Adjustment Scale Score (W&SAS) Question: Which outcome is the most appropriate for MUS/LTC? • GBU analysis
Data Validation Study Validate the self-reported co-morbidities from IAPT dataset a against CHOICE (NIHR Programme Grant) data set based on routinely collected primary and secondary healthcare data sets (i.e. Doncaster and Newham). Primary care services Acute/Secondary Services Outpatient activity In-patient activity Accident and Emergency activity • Use of medication • Psychotropic • Non-psychotropic • Referral rate
Economic analysis To ascertain the cost-effectiveness of the service in improving the outcomes of the different patient sub-groups • Convert PHQ-9 into QALYs • See Brazier, Yang , Tsuchiya , Rowen (2010) A review of studies mapping (or cross walking) non-preference based measures of health to generic preference-based measures, Eur J Health Econ. • To validate the map between PHQ-9 and EQ-5D we will also seek to identify a dataset where both PHQ-9 and EQ-5D are measured and observed and can be regressed along with interaction and polynomial effects to account for non-linearity and other confounding variables.
