ABSTRACT
BACKGROUND:
Currently, the largest available series of hip disarticulation (HD) procedures performed for periprosthetic joint infection (PJI) includes only 6 patients. Given the lack of data on this dreadful outcome, we sought to determine the frequency of and risk factors for HD performed for a primary diagnosis of PJI.METHODS:
The National Inpatient Sample from 1998 to 2016 was used to estimate the annual incidences of HD associated with PJI, elective primary total joint arthroplasty (control group 1), and other surgical procedures associated with PJI (control group 2) using National Inpatient Sample trend weights.RESULTS:
One-hundred forty-eight HDs for PJI, 2,378,313 primary total joint arthroplasty controls, and 51,580 PJI controls were identified. Median length-of-stay (11 days), proportion of patients with ≥5 comorbidities (22.8%), and median hospital costs ($25,895.60) were all greater for patients with HD compared with both control groups. The weighted frequency of HD hospitalizations increased by 366%, whereas the frequency of cases in control groups 1 and 2 increased by 93% and 310%, respectively, during the same timeframe. Upon multivariable logistic regression, age <65 years without private insurance (reference group age ≥65 years without private insurance, odds ratio [OR] 1.55; 95% confidence interval [CI] 1.08-2.24), diabetes with chronic complications (OR 1.91; 95% CI 1.12-3.26), and peripheral vascular disease (OR 2.59; 95% CI 1.49-4.48) were significantly associated with increased risk of HD among all patients with PJI.CONCLUSION:
While the overall frequency of lower extremity amputations may be decreasing, our study documents an alarming increase in the frequency of HD for PJI during the study period. Patients under age 65 years without private insurance were at significantly higher risk of HD among patients with PJI.Palavras-chave
