A nationwide analysis on the effects of chronic obstructive pulmonary disease following primary total shoulder arthroplasty for glenohumeral osteoarthritis.

BACKGROUND

Chronic obstructive pulmonary disease patients have been shown in orthopedic literature to have poorer outcomes and higher rates of complications from surgery. In this retrospective review, medical complications, length of stay, and costs were obtained to explore the effects of chronic obstructive pulmonary disease on patients undergoing primary total shoulder arthroplasty.

METHODS

Total shoulder arthroplasty cases from January 2005 to March 2014 were queried and analyzed from a nationwide database. Study patients were matched 1:5 to controls by age, sex, and medical comorbidities associated with chronic obstructive pulmonary disease. In-hospital length of stay, 90-day medical complications, day of surgery, and total global 90-day episode of care costs were obtained for comparison.

RESULTS

Chronic obstructive pulmonary disease patients were found to have higher incidence and odds (53.91 vs. 11.95%; OR: 3.58, 95%CI: 3.18-3.92, 0.0001) of 90-day medical complications, longer in-hospital length of stay (3 vs. 2 days, 0.0001), and significantly higher 90-day costs ($14,768.37 vs. $13,379.20, 0.0001) following primary total shoulder arthroplasty compared to matched controls.

DISCUSSION

Chronic obstructive pulmonary disease patients undergoing primary total shoulder arthroplasty have higher rates of medical complications, in-hospital length of stay, and costs of care. This represents an important factor that will allow orthopedic surgeons to adequately manage expectations and educate chronic obstructive pulmonary disease patients of the potential complications which may occur following total shoulder arthroplasty.
