The primary objective of this study is to describe the pathway of AD/CMA patients in terms of interaction with and burden upon the healthcare system. This burden will be measured by interactions with both Primary and Secondary care.
Patients with an age of 5 years and over from a HES-linked practice with any recorded read code diagnosis of AD AND any product used to treat CMA from the list included. The study period will be from 5 years, from April 2012 to March 2017. The index date for inclusion of a patient shall be the first diagnosis of AD and prescription of a CMA product within the study period. Outcomes would be tracked for all available time within the study period after the index date and annualised for comparison.
With the outcomes measured, the pathway of AD/CMA patients may be described, with stipulations as to the burden of care for both primary and secondary care.
