Objective: To evaluate the ability of shoulder surgery patients to recall their preoperative health status two weeks postoperatively. Study Design: We randomized consecutive patients to group I (assessments at 2 weeks preoperatively, on the day of surgery, and 2 weeks and 6 months postoperatively) or group II (assessments at 2 weeks and 6 months postoperatively). At each visit patients completed disease-specific, region-specific, and generic health instruments. At 2 weeks postoperatively, patients completed the same questionnaires according to their recollection of their health 2 weeks prior to surgery. Results: Agreement between actual and recalled data was excellent for diseasespecific (ICCworc = 0.97 (95% CI 0.91 to 0.99), ICCwosι = 0.88 (95% CI 0.73 to 0.95)), and region-specific (ICCuefi = 0.92 (95% CI 0.85 to 0.96), ICCases = 0.87 (95% CI 0.76 to 0.93)) but moderate for general physical and mental health (ICCSF-12(PCS) = 0.66 (95% CI 0.45 to 0.81), ICCSF-12(MCS) = 0.75 (95% CI 0.57 to 0.86)). Conclusion: Patients recalled their preoperative health status at 2 weeks postoperatively with sufficient accuracy to warrant substituting prospectively collected baseline data for recalled ratings.
