PURPOSE: To examine trends in Patient-Reported Outcome Measurement Information System (PROMIS) scores among orthopedic sports medicine patients undergoing surgery who completed PROMIS forms both in the ambulatory (preoperative) setting at the time of surgical scheduling as well as on the day of surgery (perioperative) prior to their procedure.

METHODS: Consecutive patients undergoing various sports medicine related surgery were recruited. Patients were included if they were scheduled for surgery and completed preoperative PROMIS on the day of surgical scheduling and on the day of surgery. Patients were excluded if they refused the questionnaire or had been administered perioperative anesthesia, which would interfere with questionnaire completion. Paired samples t-tests were run between preoperative and perioperative PROMIS scores to determine statistical significance.

RESULTS: 153 patients were included with an average age of 46.5 years. The average (SD) time between completion of PROMIS questionnaires was 46.5 (44.4) days. The absolute value change in scores between preoperative and perioperative visits was 4.09 for PROMIS UE, 3.59 for PROMIS PF, 3.67 for PROMIS PI, and 4.13 for PROMIS D. The overall net change of scores between preoperative and perioperative visits were -.57 for PROMIS UE CAT, .16 points for PROMIS PF CAT, -.85 points for PROMIS PI CAT, and -2.14 points for PROMIS D CAT. Statistically significant differences in preoperative and perioperative PROMIS PI (p=.042) and PROMIS D (p=.004) scores were found.

CONCLUSIONS: Health states - as measured by PROMIS CAT forms completed among patients undergoing orthopedic surgery - can either improve or worsen preoperatively between the time of administration in both the ambulatory and perioperative setting. Despite the existence of these preoperative trends, it is important to consider patient and surgery-specific causes, such as the anatomic region, type of surgical intervention, and timing of preoperative PROMIS administration.
