AN was involved in patient selection, medical record and questionnaire abstraction and database management.
All maternity units were asked to pull and provide, in chronological order, all medical records meeting our selection criteria.
Patients will either be referred by their GP or will receive an invitation to participate based on a selection of the electronic medical record system of the GP.
Firstly, we obtained data about health care utilization by medical record linkage of different registrations, which introduced some selection bias.
In Germany, Slovenia, Switzerland, and the Netherlands, patient selection and data extraction of the medical record audit was conducted by a practice nurse (guided by the GP).
Study strengths include the unbiased selection of exposed and unexposed groups, medical record documentation of exposure status, and a large sample size.
We conducted a retrospective medical record review to better understand the clinical variables which affect treatment selection for new-onset infantile spasms.
This study was the first to obtain qualitative opinions about medical record review both before and after provision of detailed information about selection bias and research processes.
A key selection criterion will be experience in clinical audit and medical record review.
The programme involves reading the practice electronic medical record to generate a master list of patients who satisfy the prescribed selection criteria.
