Returns to the Emergency Department (ED) and unplanned readmissions within 90 days of shoulder arthroplasty represent a significant financial burden to healthcare systems. Identifying the reasons and risk factors could potentially reduce their prevalence.  A retrospective review of primary anatomic (aTSA) and reverse shoulder arthroplasty (rTSA) cases from January 2016 through August 2023 was performed. Demographic patient and surgical data, including age, diagnosis of anxiety or depression, body mass index (BMI), smoking status, age-adjusted Charlson Comorbidity Index (ACCI), modified 5-item fragility index (mFI-5), and hospital length of stay (LOS) was collected. Patient visits to the ED within 12 months prior to surgery were recorded. Predictors for return to the ED within 90 days postoperatively and any readmissions were determined.  There were 338 cases (167 aTSA and 171 rTSA), of which 225 (67%) were women. Patients with anxiety (OR=2.44, 95% CI 1.11–5.33; P=0.026), surgical postoperative complications (OR=3.22, 95% CI 1.36–7.58; P=0.008), ED visit within 3 months prior to surgery (OR=3.80, 95% CI 1.71–8.45; P=0.001), ED visit 3 to 6 months prior to surgery (OR=2.60, 95% CI 1.12–6.05; P=0.027), and ED visit 6 to 12 months prior to surgery (OR=2.12, 95% CI 1.02–4.41; P=0.045) were more likely to have ED visit within 90 days postoperatively. Patients with prior ipsilateral shoulder surgery (OR=3.32, 95% CI 1.21–9.09; P=0.02), surgical postoperative complications (OR=13.92, 95% CI 5.04–38.42; P<0.001), an ED visit within 3 to 6 months preoperatively (OR=8.47, 95% CI 2.84–25.27; P<0.001), and an mFI-5 ≥2 (OR=3.66, 95% CI 1.35–9.91; P=0.011) were more likely to be readmitted within 90 days.  Patients who present to the ED within 12 months prior to shoulder arthroplasty, those with anxiety, those with surgical complications and those with higher fragility should be monitored closely during the early postoperative period to minimize returns to the ED and/or unplanned readmissions.  Level of evidence: III

There have been conflicting reports regarding the effects of obesity on both surgical time and blood loss following anatomic shoulder arthroplasty. Varying categories of obesity has made comparison amongst existing studies difficult. A retrospective review of consecutive anatomic shoulder arthroplasty cases (aTSA) was undertaken. Demographic data, including age, gender, body mass index (BMI), age-adjusted Charleson Comorbidity Index (ACCI), operative time, hospital length of stay (LOS), and both POD#1 and discharge visual analogue score (VAS) was collected. Intra-operative total blood volume loss (ITBVL) and need for transfusion was calculated. BMI was categorized as non-obese (<30 kg/m2), obese (30-40 kg/m2) and morbidly obese (≥40 kg/m2). Unadjusted associations of BMI with operative time, ITBVL and LOS were examined using Spearman correlation coefficients. Regression analysis was used to identify factors associated with hospital LOS. There were 130 aTSA cases performed, including 45 short stem and 85 stemless implants, of which 23 (17.7%) were morbidly obese, 60 (46.2%) were obese and 47 (36.1%) were non-obese. Median operative time for the morbidly obese cohort was 119.5 minutes (IQR 93.0, 142.0) versus 116.5 minutes (IQR 99.5, 134.5) for the obese cohort versus 125.0 minutes (IQR, 99.0, 146.0) for the non-obese cohort. (P=0.61) The median ITBVL for the morbidly obese cohort was 235.8 ml (IQR 144.3, 329.7) versus 220.1 ml (IQR 147.7, 262.7) for the obese cohort versus 216.3 ml (IQR 139.7, 315.5) for the non-obese cohort. (P=0.72). BMI ≥40kg/m2 (IRR 1.32, P=0.038), age (IRR 1.01, P=0.026), and female gender (IRR 1.54, P<0.001) were predictive of increased LOS. There was no difference with regards to in-hospital medical complications (P=0.13), surgical complications (P=1.0), need for re-operation (P=0.66) and 30-day return to the ER (P=0.06). Morbid obesity was not associated with increased surgical time, ITBVL and perioperative medical or surgical complications following aTSA, though it was predictive of increased hospital LOS.
