Abstract
An extended length of stay following open reduction and internal fixation (ORIF) for proximal humerus fractures (PHFs) is associated with increased patient morbidity and health care costs. The primary purpose of this study was to identify risk factors for an extended length of stay following ORIF for PHF. All patients who underwent ORIF for PHF between 2015 and 2021 were queried from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. Patient demographics, comorbid conditions, and postoperative complications within 30 days of procedure were collected. Extended length of stay (eLOS) was defined by ≥ 3 days from operation to discharge. Multivariate logistic regression was employed to identify predictors of eLOS following ORIF. Characteristics of patients significantly associated with eLOS included age ≥ 75 years (p < .001), male gender (p < 0.001), body mass index (BMI) < 18.5 (P= .001), American Society of Anesthesiologists (ASA) classification ≥ 3 (P < .001), dependent functional status (P < .001), noninsulin-dependent diabetes (P= .037), insulin-dependent diabetes (P < .001), chronic obstructive pulmonary disease (P < .001), congestive heart failure (CHF) (P < .001), hypertension (P < 0.001), dialysis (P < .013), disseminated cancer (P < 0.001), chronic steroid use (P= .004), and bleeding disorder (P < .001). Independent predictors of eLOS were age ≥ 75 years (OR= 2.69; P < .001), BMI < 18.5 (OR= 1.70; P= .016), ASA ≥ 3 (OR= 2.70; P < .001), dependent functional status (OR= 2.30; P < .001), CHF (OR= 3.57; P < .001), disseminated cancer (OR= 7.62; P < .001), and bleeding disorder (OR= 2.68; P < .001). Age ≥ 75, BMI < 18.5, ASA ≥ 3, functional dependence, CHF, disseminated cancer, and bleeding disorder were independently associated with eLOS. Assessing specific patient factors prior to ORIF for PHF can assist in managing perioperative risks and decreasing expenses related to eLOS. Prognosis III.
