DementiaDrugsCPRD

This respository contains the code to reproduce the analysis from the following paper:

Walker, V. M., Davies, N. M., Kehoe, P. G., & Martin, R. M. (2018). What is the impact of regulatory guidance and expiry of drug patents on dementia drug prescriptions in England? A trend analysis in the Clinical Practice Research Datalink. Alzheimer’s Research & Therapy, 10, 51. https://doi.org/10.1186/s13195-018-0379-6

Using this code

To run this code, run the file 'DementiaDrugsCPRD.do'. All other files are called when required from this file. The code is setup to work from a master file that contains a record for each patient, along with their demographic information and relevant dates for diagnoses and treatments. If you would like more information concerning the data setup, please contact venexia.walker@bristol.ac.uk.
