Data and STATA code for the paper "Did the UK Quality and Outcomes Framework pay-for-performance programme improve quality of primary care? Systematic review with quantitative synthesis"

This repository contains the data for indicators which were reanalysed in the paper:

Ho L, Mercer SW, Henderson D, Donaghy E, Guthrie B. Did the UK Quality and Outcomes Framework pay-for-performance programme improve quality of primary care? Systematic review with quantitative synthesis.

For any queries, please contact Bruce Guthrie, Professor of General Practice, University of Edinburgh [e-mail]

Data is contained in a set of Excel files. Also provided is the STATA code used in analysis which uses the itsa command to fit interrupted time series analysis models, and lincom to estimate absolute impact at 1 and 3 years after intervention. Users will have to import from wherever they save these files (our own import and graph save commands are commented out).

Please refer to these documents for details of how to use itsa and how to use lincom for this purpose.
