Orthopaedic Surgery Subspecialty Podcast Effectively Disseminates Peer-reviewed Articles Relative to Traditional Online Publishing.

BACKGROUND: Podcasts have become increasingly utilized in medical education over the past decade, especially in orthopaedic surgery. Compared with more traditional learning tools, podcasts are easily accessible, free, and capable of use while multitasking. Despite these apparent benefits, the effectiveness of podcasts as a dissemination tool for emerging peer-reviewed literature is not well understood. The Peds Ortho Podcast is the official podcast of Pediatric Orthopedic Society of North America that highlights recently published peer-reviewed articles through author interviews and executive summaries of featured articles. The purpose of this study was to compare the distribution of the Peds Ortho Podcast to traditional media by comparing electronic access statistics between the podcast episodes and the journal articles they summarize. METHODS: Podcast episodes were reviewed to catalog the abstracts and articles discussed therein. Because podcasts and articles utilize different electronic metrics to track distribution, we established a common metric of an "access," which we defined as an "intent to consume the media." For articles, we defined an "access" as the largest value of a publisher's online metrics, be it abstract views, full text views, or article downloads. For podcast episodes, we defined an "access" as any play >0 seconds. Access data were analyzed using independent samples t test and analyses of variance. RESULTS: Eighty episodes of the Peds Ortho Podcast have featured 333 published, peer-reviewed articles to date, with 303 included in the final analysis with available article metrics. There were significantly more mean electronic accesses per podcast episode than featured articles (1236 vs. 482, P <0.001). Podcast consumption greatly varies in the first 30 days following episode release; however, recent episodes have a substantial proportion of accesses soon after publication. CONCLUSIONS: Given that podcast electronic access is greater than traditional media, podcasts appear to be a valuable tool for health care providers and trainees. Podcasts serve a complementary role to traditional media by quickly disseminating main points and raising awareness of emerging research.

Vitamin D deficiency in Scheuermann's disease is associated with increased adverse outcomes.

INTRODUCTION: Scheuermann's disease is a diagnosis of hyperkyphosis commonly encountered in pediatric patients. Studies in animal models suggest an association with vitamin D deficiency, however, extensive studies have not been performed in humans. This study analyzes the role of vitamin D deficiency on unfavorable results in patients with Scheuermann's disease. METHODS: The TriNetX database was utilized to perform a retrospective analysis. Patients in the United States aged 0-18 years with Scheuermann's disease were identified using International Classification of Diseases, Tenth Revision (ICD-10) codes and categorized into those with and without a diagnosis of vitamin D deficiency. Comparison of patient groups depending on age, sex, ethnic origin, prior diagnosis of fibromyalgia, anxiety disorder, myositis, and major depressive disorder. Statistical analysis was conducted to identify the association between vitamin D levels and unfavorable results including pain, depression, suicide attempt, emergency department (ED) consult, hospitalization, and procedures on the spine or spinal cord. RESULTS: In total, 11,277 patients were identified, 39% of whom had a concurrent diagnosis of scoliosis. A total of 1,024 (9.08%) were deficient in vitamin D. Patients with vitamin D deficiency had greater odds of pain (P < 0.0001), depression (P < 0.0001), suicide attempt (P = 0.0021), ED visits (P = 0.0246), and hospital admission (P < 0.0015). Conversely, patients with vitamin D deficiency had decreased odds of surgery on the spine or spinal cord (P = 0.0009). CONCLUSION: Vitamin D deficiency is associated with an elevated risk of pain, depression, suicide attempts, ED visits, and hospitalization. Our analysis highlights the need for more research to study the effect of vitamin D on Scheuermann's disease. LEVEL OF EVIDENCE: Level III, Prognostic.

Risk factors, causes, and the economic implications of unplanned readmissions following total hip arthroplasty.

In order to identify risk factors for readmissions following total hip arthroplasty (THA) and the causes and financial implications of such readmissions, we analyzed clinical and administrative data on 1583 consecutive primary THAs performed at a single institution. The 30-day readmission rate was 6.51%. Increased age, length of stay, and body mass index were associated with significantly higher readmission rates. The most common re-admitting diagnoses were deep infection, pain, and hematoma. Average profit was lower for episodes of care with readmissions ($1548 vs. $2872, P=0.028). If Medicare stops reimbursing for THA readmissions, the institution under review would sustain an average net loss of $11,494 for episodes of care with readmissions and would need to maintain readmission rates below 23.6% in order to remain profitable.
