METHODS All consecutive shoulder arthroscopy procedures performed during a 10-year period were reviewed. A 2:1 control-case matching technique was used. Univariate analysis was performed to identify differences between patients admitted after surgery and the control group. Multivariate analysis was performed to identify variables associated with admission.
RESULTS There were 5598 arthroscopic shoulder procedures performed, with 233 patients (4.2%) requiring admission. The most common reason for admission was respiratory monitoring. Risk factors for admission by multivariate analysis were chronic obstructive pulmonary disease (odds ratio [OR], 2.73; 95% confidence interval [CI], 1.51-4.95), diabetes (OR, 2.11; 95% CI, 1.28-3.48), obstructive sleep apnea (OR, 1.90; 95% CI, 1.13-3.21), age (OR, 1.02; 95% CI, 1.01-1.04), body mass index (OR, 1.04; 95% CI, 1.01-1.07), and operative time (OR, 1.01; 95% CI, 1.00-1.01). Regional with monitored anesthesia care decreased risk compared with general anesthesia and regional with general anesthesia (OR, 0.44; 95% CI, 0.30-0.63).
CONCLUSION Chronic obstructive pulmonary disease, obstructive sleep apnea, diabetes, increasing age, increasing body mas index, and increasing operative time were all risk factors for admission after shoulder arthroscopy. The absence of general anesthesia was found to decrease the risk of admission.
