Westermann et al identfied risk factors for 30-day unplanned readmission of a patient following shoulder or knee arthroscopy. These can help to identify a patient who may be at greater risk. The authors are from the University of Iowa.

Patient selection: knee or shoulder arthroscopy


Outcome: 30-day unplanned readmission

Frequency of outcome: 0.92%


Most readmissions were for wound-related complications.


Risk factors for unplanned readmission from the multivariate logistic regression model:

(1) age > 80 years of age (odds ratio 3.5)

(2) ASA class 3 or 4 (odds ratios 1.9 and 4.2 respectively)

(3) chronic steroid use (odds ratio 3.3)


Many of the patients had high levels of comorbidity (dyspnea, COPD, cancer, diabetes, etc).


Recommendations for surgeons:

(1) careful perioperative wound management including site preparation

(2) venous thromboembolism prophylaxis

(3) pain management


Special attention should be paid to patients with one or more risk factors.
