Hidradenitis Suppurativa Leads to Increased Risk of Wound-Related Complications following Total Joint Arthroplasty.

ABSTRACT:

Background

Hidradenitis suppurativa (HS) is a skin disorder characterized by inflammatory skin lesions that are most commonly in the inguinal and axillary regions. These skin lesions are common sites of bacterial growth and are thus a potential risk factor for infection following procedures such as total hip arthroplasty (THA) or total knee arthroplasty (TKA).

Material and methods

Adult patients undergoing THA or TKA for degenerative etiologies were identified from PearlDiver datasets. For THA and TKA, HS patients were matched 1:4 with non-HS patients based on age, sex, and Elixhauser Comorbidity Index. The incidence of 90-day any, severe, minor, and specific adverse events was compiled and compared with multivariate analyses. Five-year revision rates were plotted on Kaplan-Meier survival curves and compared with log-rank tests.

Results

For THA, 331,627 patients were identified, of which HS was noted for 481 patients (0.15%). For TKA, 274,161 patients were identified, of which HS was noted for 290 patients (0.11%). Following THA, HS patients had increased odds of wound dehiscence (odds ratio = 2.55, P = .002). Following TKA, HS patients had increased odds of surgical site infection (odds ratio = 1.95, P = .006). All other 90-day adverse events were not significantly different. There was no significant difference in 5-year implant survival in either procedure.

Conclusions

HS is a rare but identified comorbidity for those undergoing THA or TKA. Although most 90-day adverse events and 5-year implant survival were similar to those without this condition, specific wound-related issues were elevated by roughly twofold. These findings could help inform patients and surgeons.

Project description:Background:With an increasing volume of primary total shoulder arthroplasties (TSA), the number of revision TSA cases is expected to increase as well. However, the postoperative medical morbidity of revision TSA has not been clearly described. Questions/Purposes:The purpose of this study was to determine the rate of postoperative complications following revision TSA, relative to primary TSA. In addition, we sought to identify independent predictors of complications, as well as to compare operative time and postoperative length of stay between primary and revision TSA. Methods:Patients who underwent primary/revision TSA between 2005 and 2015 were identified in the American College of Surgeons National Surgical Quality Improvement Program. Differences in complications, readmission rates, operative time, length of stay, and predictors of complications were evaluated using bivariate and multivariate analyses. Results:A total of 10,371 primary TSA (95.4%) and 496 revision TSA cases (4.6%) were identified. The overall complication rate was 6.5% in primary and 10.7% in revision TSA patients (p < 0.001). Multivariate analysis identified an increased risk of any complication (odds ratio 1.73, p < 0.001), major complication (2.08, p = 0.001), and wound infection (3.45, p = 0.001) in revision TSA patients, relative to primary cases. Operative time was increased in revision cases (mean ± standard deviation, 125 ± 62.5), relative to primary (115 ± 47.7, p < 0.001). Age > 75, female sex, history of diabetes or chronic obstructive pulmonary disease, and American Society of Anesthesiologists classification ? 3 were associated with increased risk of any complication. Smoking history was the only significant predictor of wound infection. Conclusion:Revision TSA, in comparison to primary, poses an increased risk of postoperative complications, particularly wound infections. A history of smoking was an independent predictor of wound infections.

Project description:BackgroundThe expansion of state Medicaid programs under the U.S. Affordable Care Act has led to a dramatic increase in the number of Americans with health insurance coverage. Prior analyses of a limited number of states have suggested that greater utilization of total hip arthroplasty (THA) and total knee arthroplasty (TKA) should be expected after Medicaid expansion. The purpose of our study was to examine whether increased utilization of THA and TKA occurred across a broader range of states after Medicaid expansion.MethodsWe analyzed administrative data from the Healthcare Cost and Utilization Project from 9 states (Arkansas, Arizona, Colorado, Iowa, Massachusetts, Maryland, Nevada, New York, and Vermont) that expanded Medicaid in 2014 and 2 states that did not expand Medicaid (Florida and Missouri). We included patients who were 18 to 64 years of age and had a primary THA or TKA from 2012 to 2015 with Medicaid as the primary payer. Other payers (including dual-eligible Medicaid and Medicare beneficiaries) were excluded. We performed multivariable regression modeling with the number of Medicaid-insured THAs or TKAs as the dependent variable and the interaction between the state Medicaid expansion status and year as the main policy independent variable, with adjustment for community characteristics.ResultsAmong all 11 states, there were 39,452 total joint arthroplasties (42% THA and 58% TKA) funded by Medicaid from 2012 to 2015. After adjusting for community characteristics, within expansion states, compared with 2013, THA and TKA increased 15% in 2014 (p < 0.0001) and 23% in 2015 (p < 0.0001) within expansion states. Within non-expansion states, compared with 2013, there were significant utilization decreases of 18% in 2014 (p < 0.0001) and 11% in 2015 (p = 0.0002).ConclusionsMedicaid expansion was associated with significant increases in Medicaid-funded THA and TKA utilization in 9 states. As additional states consider expanding Medicaid programs and as alternative health reforms that increase insurance eligibility are debated, surgeons, administrators, and policymakers should prepare for a surge in the utilization of THA and TKA.
