A Regional Analysis of Hospital Readmissions Following Total Hip and Knee Arthroplasty and the Impact of Medicaid Expansion.

The Hospital Readmissions Reduction Program (HRRP) works to temper nationally rising readmission rates. Total knee arthroplasty (TKA) and total hip arthroplasty (THA) have a 30-day readmission cost burden of $889,300 and $689,400, respectively. No research has compared TKA and THA readmission rates by region and Medicaid expansion status. This study compares THA and TKA readmission rates in the United States by region, Medicaid status, and performance. One-way ANOVAs were conducted to determine the regions with the highest and lowest mean excess readmission ratios (ERRs). An independent t-test compared Medicaid versus non-Medicaid expansion states. Southern hospitals have the highest mean ERR, followed by northeastern, midwestern, and then western hospitals. Although Medicaid expansion states have significantly lower ERRs compared to non-expansion states, Medicaid status alone does not account for regional differences in ERRs after THA and TKA. Regional factors likely confound Medicaid status's effect on readmission rates. (Journal of Surgical Orthopaedic Advances 32(1):005-008, 2023).

Epiphysiodesis for Leg Length Discrepancy: A Cost Analysis of Drill Versus Screw Technique.

Research has demonstrated similar efficacy of drill epiphysiodesis and percutaneous epiphysiodesis using transphyseal screws for the management of adolescent leg length discrepancy. A cost analysis was performed to determine which procedure is more cost-effective. Patients seen for epiphysiodesis of the distal femur and/or proximal tibia and fibula between 2004 and 2017 were reviewed. A decision analysis model was used to compare costs. Two hundred thirty-five patients who underwent either drill (155/235, 66%) or screw (80/235, 34%) epiphysiodesis were analyzed with an average age at initial procedure of 13 years (range, 8.4 to 16.7 years). There was no significant difference in average initial procedure cost or total cost of all procedures across treatment groups (n = 184). The cost difference between drill and screw epiphysiodesis is minimal. In order for screw epiphysiodesis to be cost-favored, there would need to be a significant decrease in its cost or complication rate. (Journal of Surgical Orthopaedic Advances 30(3):181-184, 2021).

Trends in Leadership at Pediatric Orthopaedic Fellowships.

BACKGROUND: Pediatric orthopaedic fellowship directors (FDs) have a valuable impact on the education of trainees and future leaders in the field. There is currently no research on the characteristics of pediatric orthopaedic FDs. METHODS: Programs were identified using the Pediatric Orthopaedic Society of North America fellowship directory. Operative, nonoperative, and specialty programs were included. Data was collected through Qualtrics survey, e-mail, telephone, and online searches. Variables included demographics (age, sex, race/ethnicity), Hirsch index (h-index) as a measure of research productivity, graduate education, residency and fellowship training, years of hire at current institution and as FD, and leadership roles. RESULTS: Fifty-five FDs were identified. The majority (49/55, 89%) were male and 77% (27/35) were Caucasian. The mean age at survey was 51.1±8.2 years. The mean h-index was 17.2. Older age correlated with higher h-index (r=0.48, P=0.0002). The average duration from fellowship graduation to FD appointment was 9.6±6.7 and 6.9±6.1 years from institutional hire. Sixteen FDs (29%) had additional graduate level degrees. Almost all (52/55, 95%) FDs completed orthopaedic surgery residencies and all graduated fellowship training. Twenty-nine percent (16/55) completed more than 1 fellowship. Most FDs (51/55, 93%) completed a fellowship in pediatric orthopaedic surgery. Ten FDs (18%) completed pediatric orthopaedic surgery fellowships that included spine-specific training. One-third of all current FDs were fellowship-trained at either Boston Children's Hospital (9/55, 16%) or Texas Scottish Rite Hospital for Children (9/55, 16%). CONCLUSIONS: Pediatric orthopaedic FDs are typically early-career to mid-career when appointed, with a strong research background. Nearly a third completed additional graduate degrees or multiple fellowships. Although male dominated, there are more female FDs leading pediatric orthopaedic programs compared with adult reconstruction, trauma, and spine fellowships. As fellowships continue to grow and diversify, this research will provide a baseline to determine changes in FD leadership.

Changing practice patterns: the impact of a cost analysis project on surgeons' preference for treatment of pediatric displaced humeral lateral condyle fractures.

A 2012 publication regarding the surgical management of pediatric lateral humeral condyle fractures (PLHCF) found that leaving pins exposed produced an average savings of $3442 per patient compared to burying pins, with fewer complications. The primary objective of this present study was to determine the impact of this cost analysis on surgeons' treatment preferences at the same hospital. The secondary aim was to verify that leaving pins exposed continued to be a cost-effective and safe treatment strategy. We reviewed all PLHCF treated with open reduction and internal fixation at our institution between 2004 and 2017. The Clavien-Dindo Classification was used to grade complications. Variations in treatment course were evaluated using a chi-squared test to compare the proportions of buried and exposed pins, pre- and postcost analysis report publication. Two hundred forty-eight patients were included. The mean age was 5.9 years (range 1-12 years). In 174 (70%) cases, the pins were buried and in the remaining 30% the pins were exposed. Between 2004 and 2012, the majority of pins were buried (90%) compared to between 2013 and 2017, when the majority of pins were exposed (62%) (P < 0.001). There was no difference detected in complication rate (P = 0.75) or complication severity (P = 0.61) across groups. The demonstrated cost-effectiveness of exposing the pins in the treatment of PLHCF has had a statistically significant impact on surgeon behavior at our institution. Publishing cost analysis research can change physician practice to improve quality, safety and value of care delivery.
