Economic and educational disparities are associated with an increased risk of revision surgery following shoulder arthroplasty

The Association Between Social Determinants of Health and Distal Radius Fracture Outcomes

PURPOSE

The purpose of this study was to determine if adverse social determinants of health (SDOH) are associated with differential complication rates following surgical fixation of distal radius fractures and assess which SDOH domain (economic, educational, social, health care, or environmental) is most associated with postoperative complications.

METHODS

Using a national administrative claims database, we conducted a retrospective cohort analysis of patients undergoing open treatment for an isolated distal radius fracture between 2010 and 2020. Patients were stratified based on the presence/absence of at least one SDOH code and propensity score matched to create two cohorts balanced by age, sex (male or female), insurance type, and comorbidities. Social determinants of health examined included economic, educational, social, health care, and environmental factors. Multivariable logistic regression analyses were performed to assess the isolated effect of SDOH on 90-day and 1-year complication rates.

RESULTS

After propensity matching, 57,025 patients in the adverse SDOH cohort and 57,025 patients in the control cohort were included. Patients facing an adverse SDOH were significantly more likely to experience 90-day complications, including emergency department visits (Odds ratio (OR): 3.18 [95% confidence interval (CI): 3.07-3.29]), infection (OR: 2.37 [95% CI: 2.12-2.66]), wound dehiscence (OR: 2.06 [95% CI: 1.72-2.49]), and 1-year complications, including complex regional pain syndrome (OR: 1.35 [95% CI: 1.15-1.58]), malunion/nonunion (OR: 1.18 [95% CI: 1.08-1.29]), and hardware removal (OR: 1.13 [95% CI: 1.07-1.20]). Additionally, patients facing an adverse SDOH had a significantly increased risk of 90-day complications, regardless of fracture severity, and patients with economic and social challenges had the highest odds of both 90-day and 1-year postoperative complications.

CONCLUSIONS

Social determinants of health are associated with increased complications following distal radius fracture fixation, even when controlling for demographic and clinical factors. We recommend routine screening for adverse SDOH and inclusion of SDOH data into health records to not only inform quality improvement initiatives and risk adjustment for outcome-based quality measurements but also to allow providers to begin to discuss and address such barriers during the perioperative period.

Social determinants of health disparities impact postoperative complications in patients undergoing total shoulder arthroplasty

BACKGROUND

Understanding the role of social determinants of health disparities (SDHDs) in surgical outcomes can better prepare providers to improve postoperative care. In this study, we use International Classification of Diseases (ICD) codes to identify SDHDs and investigate the risk of postoperative complication rates among patients undergoing total shoulder arthroplasty (TSA).

METHODS

A retrospective cohort analysis was conducted using a national insurance claims database. Using ICD and Current Procedural Terminology (CPT) codes, patients who underwent primary TSA with at least 2 years of follow-up in the database were identified. Patients with a history of SDHDs were identified using appropriate ICD-9 and ICD-10 codes. Patients were grouped in one of 2 cohorts: (1) patients with no history of SDHDs (control) and (2) patients with a history of SDHDs (SDHD group) prior to TSA. The SDHD and control groups were matched 1:1 for comorbidities and demographics prior to conducting multivariable analysis for 90-day medical complications and 2-year surgical complications.

RESULTS

After matching, there were 8023 patients in the SDHD group and 8023 patients in the control group. The SDHD group had significantly higher odds for 90-day medical complications including heart failure, cerebrovascular accident, renal failure, deep vein thrombosis, pneumonia, sepsis, and urinary tract infection. Additionally, the SDHD group had significantly higher odds for revision surgery within 2 years following TSA. Patients in the SDHD group also had a significantly longer length of hospital stay following TSA.

DISCUSSION

This study highlights the association between SDHDs and postoperative complications following TSA. Quantifying the risk of complications and differences in length of stay for TSA patients with a history of SDHDs is important in determining value-based payment models and risk stratifying to optimize patient care.

Outcome of reverse shoulder arthroplasty secondary to rotator cuff arthropathy in a low-income population

BACKGROUND

Reverse shoulder arthroplasty (RSA) is a valuable treatment for rotator cuff arthropathy (RCA) in developed regions. Socioeconomic issues impact access to specialized care and there is a lack of data on RSA outcomes in developing regions. We present our 24-month follow-up on RSA surgeries to treat RCA in our low-income population.

METHODS

Prospective evaluation of 26 patients subjected to RSA at Hospital Geral de Fortaleza-CE, Brazil, between January 2018 and December 2020. Literacy [>/≤ 8 school years(SY)] and income were documented. Outcomes considered pain (visual analogue scale; VAS) as well as SSV, SPADI, ASES, and UCLA scoring, and range of motion [forward flexion (FF); external rotation (ER)].

RESULTS

Patients were 68.5 ± 7.6 years-old with 16(61.5%) females; 65% had hypertension and 7 (26.9%) had diabetes. Over 90% declared < 900.00 US$ monthly family earnings and 10 (38.4%) patients declared ≤8 SY with > 80% exerting blue-collar jobs. Pain showed a significant reduction from baseline (8 ± 2) to 24 months (2.1 ± 2.3; p < 0.001). UCLA (10.3 ± 5.6 and 28.6 ± 7.2), ASES (16.7 ± 10.8 and 63.1 ± 28.4), SSV (326 ± 311 and 760 ± 234), and SPADI (98.3 ± 26.5) scores significantly improved from baseline to 24 months, achieving minimal clinically important difference. FF (89.2° ± 51.2° to 140.6 ± 38.3°) and ER (19.2° ± 22.5 to 33.4° ± 20.6°) significantly improved from baseline to 24 months (p = 0.004 and 0.027, respectively). There were 5 non-serious adverse events with one surgical revision. All patients returned to daily life activities.

CONCLUSION

This is the first outcome report 2 years following RSA in a low-income population. Data indicate this procedure is justifiable regardless of socioeconomic issues.
