Impact of tobacco usage on readmission and complication rates following shoulder replacement surgery: A study of 164,527 patients

Effect of tobacco usage on surgical site wound problems after primary total hip and total knee arthroplasty: A meta-analysis

The meta-analysis aims to assess and compare the effect of tobacco usage on surgical site wound problems (SSWPs) after primary total hip and total knee arthroplasty (PTH&TKA). Using dichotomous random- or fixed-effects models, the outcomes of this meta-analysis were examined, and the odds ratio (OR) with 95% confidence intervals (CIs) was computed. Fifteen studies from 2001 to 2023 were enrolled for the present meta-analysis including 560 819 personals with PTH&TKA. Smokers had significantly higher SSWPs (OR, 1.53; 95% CI, 1.21-1.94, p < 0.001) compared with non-smokers in personals with PTH&TKA. Current smokers had significantly higher SSWPs (OR, 1.59; 95% CI, 1.40-1.80, p < 0.001) compared with non-smokers in personals with PTH&TKA. Current smokers had significantly higher SSWPs (OR, 1.42; 95% CI, 1.19-1.70, p < 0.001) compared with former smokers in personals with PTH&TKA. However, former smokers and non-smokers had no significant difference in SSWPs (OR, 1.11; 95% CI, 0.95-1.30, p = 19) in personals with PTH&TKA. The examined data revealed that in personals with PTH&TKA smokers had significantly higher SSWPs compared with non-smokers, and current smokers had significantly higher SSWPs compared with non-smokers and former smokers; however, former smokers and non-smokers had no significant difference in SSWPs. Yet, attention should be implemented while relating to its values since some of the comparisons were made using a low number of selected studies.

The impact of tobacco use on clinical outcomes and long-term survivorship after anatomic total shoulder arthroplasty

Introduction

Postoperative outcomes following total shoulder arthroplasty can be affected by preoperative health factors such as tobacco usage.

Methods

The charts of patients who underwent anatomic total shoulder arthroplasty were retrospectively analyzed and stratified based on smoking status. The primary data included range of motion and patient reported outcomes. Additionally, demographic, radiographic, and survivorship analyses were conducted. All data were analyzed using statistical inference.

Results

There were 78, 49, and 16 non-smoker, former smoker, and current smoker shoulders respectively with no significant differences in sex, American Society of Anesthesiologists status, body mass index, or mean follow-up time (average: 10.7 yrs). Smokers (51.5 ± 10.4 years) were younger than both non-smokers (64.9 ± 8.1 years; p < 0.01) and former smokers (65.1 ± 9.1years; p < 0.01) at the time of surgery. For non-smokers and former smokers, all range of motion and patient reported outcome scores significantly improved. Smokers reported significant improvements in all patient reported outcomes and external and internal rotation. Visual Analog Scale, American Shoulder and Elbow, and Simple Shoulder Test scores were lower for smokers comparatively, but these differences did not reach significance. Forward elevation was higher postoperatively for non-smokers (149.7o ± 17.2o) and former smokers (147.1o ± 26.0o) compared to current smokers (130.9o ± 41.2o; p = 0.017). No differences between the cohorts were found in the radiographic analysis. Revision rates were lower in the non-smoking cohort (7.7%) compared to both former (20.4%; p = 0.036) and current smokers (37.5%; p < 0.01). Survival curves showed that non-smoker implants lasted longer than those of current smokers.

Conclusion

After a decade, patients generally had improved shoulder range of motion, functionality, and pain regardless of smoking status. However, current smokers required shoulder replacements sooner and revision surgery more frequently.

A national analysis of the effect alcohol use disorder has on short-term complications and readmissions following total shoulder arthroplasty

Background

Alcohol use disorder has been associated with broad health consequences that may interfere with healing after total shoulder arthroplasty. The aim of this study was to explore the impact of alcohol use disorder on readmissions and complications following total shoulder arthroplasty.

Methods

We used data from the Healthcare Cost and Utilization Project National Readmissions Database (NRD) from 2016 to 2018. Patients were included based on International Classification of Diseases, 10th Revision (ICD-10) procedure codes for anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA). Patients with an alcohol use disorder (AUD) were identified using the ICD-10 diagnosis code F10.20. Demographics, complications, and 30-day and 90-day readmission were collected for all patients. A univariate logistic regression was performed to investigate AUD as a factor affecting readmission and complication rates. A multivariate logistic regression model was created to assess the impact of alcohol use disorder on complications and readmission while controlling for demographic factors.

Results

In total, 164,527 patients were included, and 503 (0.3%) patients had a prior diagnosis of AUD. Revision surgery was more common in patients with an alcohol use disorder (8.8% vs. 6.2%; p = 0.022). Postoperative infection (p = 0.026), dislocation (p = 0.025), liver complications (p < 0.01), and 90-day readmission (p < 0.01) were more common in patients with a diagnosed AUD. On multivariate analysis, patients with an AUD were found to be at increased odds for liver complications (OR: 46.8; 95% CI: [32.8, 66.8]; p < 0.01). Comparatively, mean age, length of stay, and over healthcare costs were also higher for patients with an AUD.

Conclusion

Patients with a diagnosis of AUD were more likely to suffer from shoulder dislocation, liver complications, and 90-day readmission, while also being younger and having longer hospital stays. Therefore, surgeons should take caution to anticipate and prevent complications and readmissions following total shoulder arthroplasty in patients with an AUD.
