The RESIO study was undertaken to test the feasibility of collecting PROMs on a routine basis. From November 1999 to September 2000, 5,313 consecutive patients having cataract replacement surgery, cholecystectomy, hysterectomy, lumbar discectomy, prostatectomy, or total hip replacement completed a pre- and post-surgery survey of their health related quality of life (HRQOL).
