INPS, has written unobtrusive anonymous data collection software for Vision practices that have joined THIN.
Upon joining THIN an initial Full Data Collection (FDC), which includes all retrospective data, is sent to THIN. Following this, incremental data are collected automatically and downloaded electronically each month. This method of data collection ensures minimal disruption to daily practice activities.
THIN Data collection commenced in November 2002, although FDC means that computerised records available for research go back to around 1988 for some patients. To date more than 550 Vision practices have joined the scheme.
