Results published in The American Journal of Sports Medicine showed patients with gout had a relatively higher risk for undergoing rotator cuff repair, especially for patients aged 50 years or younger and without hypouricemic medication control.
Using a 7-year longitudinal follow-up of patients from the Taiwan Longitudinal Health Insurance Database 2005, researchers matched 32,723 patients with gout to 65,446 patients without gout by propensity scores. Researchers obtained missing confounding variables from the database through a two-stage approach that used the National Health Interview Survey 2005.
Results showed an incidence of rotator cuff repair of 31 per 100,000 person-years in the gout cohort vs. 18 per 100,000 person-years in the control cohort. During the 7-year follow-up period, researchers noted a crude HR of 1.73 for rotator cuff repair in the gout cohort. According to results, the gout cohort had a propensity score calibration-adjusted HR of 1.60 after adjustment for covariates by use of the two-stage approach. Researchers also found an adjusted HR of 1.73 and 2.70 among patients with gout who did not take hypouricemic medication and patients with gout aged 50 years or younger, respectively. – by Casey Tingle
