The anterior approach (AA) for total hip arthroplasty (THA) is associated with more rapid recovery when compared to traditional approaches. The purpose of this study was to benchmark healthcare resource utilization and costs for patients with THA via AA relative to matched patients.This study queried Medicare claims data (2012-2014) to identify patients who received THA via an AA from experienced surgeons, and matched these patients to a control cohort (all THA approaches). Direct and propensity-score matching were employed to maximize similarity between patients and hospitals in the two cohorts. Hospital length of stay (LOS), the proportion of patients discharged to home or home health, and post-acute claim payments during the 90-day episode were assessed. Generalized estimating equations were applied to control for imbalances between the cohorts and clustering of outcomes within hospitals.A total of 1,794 patients were included after patient matching. Patients who received AA had significantly lower mean hospital LOS vs patients in the control group (2.06 ± 1.36 vs 2.98 ± 1.58 days, p .0001). The adjusted proportion of patients discharged to home was nearly 20 percentage points higher in the AA cohort vs the control cohort (87.3% vs 68.7%, p .0001). Post-acute claim payments for AA patients were nearly 50% lower than those for control patients ($4,139 vs $7,465, p .0001).AA patients had significantly lower post-acute care resource use when compared to control patients. Further research is warranted to evaluate the cost effectiveness of AA among surgeons of varying experience levels.

The frequency of primary and revision total knee and hip replacements (pTKRs, rTKRs, pTHRs, and rTHRs, respectively) is increasing in the United States due to demographic changes. This study evaluated the impact of preoperative patient and clinical factors on the risk of surgical site infection (SSI) within the 90-day period after primary and revision total joint replacements (TJR).A retrospective observational cohort study was designed using the IBM MarketScan and Medicare databases, 2009-2015. Thirty-four comorbidities were assessed for all patients, and multivariable logistic regression models were used to evaluate factors associated with higher odds of SSI after adjusting for other patient and clinical preoperative conditions.The study included a total of 335,134 TKRs and 163,547 THRs. SSI rates were 15.6% and 8.6% after rTKR and rTHR, respectively, compared with 2.1% and 2.1% for pTKR and pTHR, respectively. Comorbidities with the greatest adjusted effect on SSI across all TJRs were acquired immunodeficiency syndrome (odds ratio [OR], 1.58; 95% confidence interval [CI], 1.06-2.34; P = .0232), paralysis (OR, 1.56; 95% CI, 1.26-1.94; P.0001), coagulopathy (OR, 1.48; 95% CI, 1.36-1.62; P.0001), metastatic cancer (1.48; 95% CI, 1.24-1.76; P.0001), and congestive heart failure (OR, 1.39; 95% CI, 1.30-1.49; P.0001).SSI occurred most commonly among patients after revision TJR and were related to many patient comorbidities, including diabetes, congestive heart failure, and coagulopathy, which were significantly associated with a higher risk of SSI after TJR.

Purpose of study Low back pain is one of the most prevalent and disabling musculoskeletal conditions affecting the working population in the United States. Informed, shared decision making among patients, clinicians, and case managers about treatment options for chronic low back pain-including the role of spinal fusion where medically necessary-can have a meaningful impact on return to work, normal function, and economic outcomes. Minimally invasive techniques for lumbar spinal fusion, including transforaminal lumbar interbody fusion (MIS TLIF) have recently been introduced with the goal of smaller operative wounds, less tissue trauma, and faster postoperative recovery when compared with open fusion. Although similar long-term clinical outcomes have been reported for MIS TLIF and open TLIF, the relative merits with respect to workplace productivity have not been comprehensively investigated. Time to return to work and narcotic independence after MIS TLIF and open TLIF are important parameters that may affect overall workplace productivity, and as such are the focus of this study. Primary practice setting(s) This study was performed via a review of the literature. Methodology and sample We performed a systematic literature review to identify all published articles that reported on the postoperative outcomes of patients, as assessed by return to work or narcotic independence status or both, following MIS TLIF or open TLIF. A cumulative comparison was made for all included MIS TLIF versus open TLIF surgeries. Results Seventy-four published studies reported postoperative outcomes following MIS TLIF or open TLIF; only five (6.8%) studies directly described time to return to work or duration of narcotic use postoperatively or both, and were therefore included into the analysis of this review. Four studies in the published literature describe time to return to work following MIS TLIF or open TLIF, and two studies describe time to narcotic independence. Overall, the reviewed literature suggests that MIS TLIF may be associated with an accelerated time to narcotic independence and return to work versus open TLIF. Implications for case management practice There are limited data regarding time to return to work and duration of postoperative narcotic use following TLIF for low back pain. The available data appear to suggest that MIS TLIF may be associated with accelerated return to work and narcotic independence compared with open TLIF. Further analysis will be necessary to quantify the impact of MIS TLIF on workplace productivity and the indirect costs borne by patients and employers. Such information will be of value to case managers, disability managers, employers, patients, and clinicians aligned on reducing morbidity and hastening return to normal function.
