AI Article Synopsis
- The study highlights the importance of expert witness testimony in orthopaedic surgery malpractice cases and examines the characteristics of these witnesses from 2013 to 2017.
- The research found that a greater number of expert witnesses testified for plaintiffs compared to defendants, with general orthopaedists being the most common type on both sides.
- Key differences emerged between plaintiff and defense witnesses, including years of experience, academic involvement, fellowship training, and scholarly impact, indicating potential biases in expert testimony.
Article Abstract
Background: According to the American Academy of Orthopaedic Surgeons (AAOS) Standards of Professionalism, the responsible testimony of expert witnesses in orthopaedic surgery malpractice lawsuits is important to the public interest. However, these expert witnesses are recruited and compensated without established standards, and their testimony can potentially sway court opinion, with substantial consequences. The objective of this study was to characterize defense and plaintiff expert orthopaedic surgeon witnesses in orthopaedic surgery malpractice litigation.
Methods: Utilizing the WestlawNext legal database, defense and plaintiff expert witnesses involved in orthopaedic surgery malpractice lawsuits from 2013 to 2017 were identified. Each witness's subspecialty, mean years of experience, involvement in academic or private practice, fellowship training, and scholarly impact, as measured by the Hirsch index (h-index), were determined through a query of professional profiles, the Scopus database, and a PubMed search. Statistical comparisons were made for each parameter among defense and plaintiff expert witnesses.
Results: Between 2013 and 2017, 306 expert medical witnesses for orthopaedic cases were identified; 174 (56.9%) testified on behalf of the plaintiff, and 132 (43.1%) testified on behalf of the defense. Orthopaedic surgeons who identified themselves as general orthopaedists comprised the largest share of expert witnesses on both the plaintiff (n = 61) and defense (n = 25) sides. The plaintiff witnesses averaged 36 years of experience versus 31 years for the defense witnesses (p < 0.001); 26% of the plaintiff witnesses held an academic position versus 43% of the defense witnesses (p = 0.013). Defense witnesses exhibited a higher proportion of fellowship training in comparison to plaintiff expert witnesses (80.5% versus 64.5%, respectively, p = 0.003). The h-index for the plaintiff group was 6.6 versus 9.1 for the defense group (p = 0.04). Two witnesses testified for both the plaintiff and defense sides.
Conclusions: Defense expert witnesses held higher rates of academic appointments and exhibited greater scholarly impact than their plaintiff counterparts, with both sides averaging >30 years of experience. These data collectively show that there are differences in characteristics between plaintiff and defense witnesses. Additional study is needed to illuminate the etiology of these differences.

Purpose: Age-related cataract (ARC) remains one of the leading causes of blindness globally. Despite the satisfactory outcomes of surgical interventions, significant disparities in access to medical care prevent many patients from receiving effective treatment. Thus, identifying reliable biomarkers and therapeutic targets to expand treatment options for ARC is essential.

Understanding how systemic racism impacts care and learning from families of color about their experiences can provide critical insights for improving clinical practice and engaging patients equitably in ADHD care. We interweave a mother's experience navigating ADHD care for her son with commentary from an interprofessional team about what clinicians can do for families to reduce the impact of systemic racism on care.

Objectives: This study aims to assess the correlation between clinical features and mortality in human immunodeficiency virus (HIV)-infected individuals with COVID-19.
Methods: A systematic literature search was conducted for cohort, cross-sectional, and case series that reported co-infection with HIV and COVID-19 published from January to September 2020. Clinical features such as age, comorbidities, CD4T lymphocyte counts, HIV RNA levels, and antiretroviral regimens were evaluated using meta-analyses and systematic reviews.

Background: The onset of the coronavirus disease 2019 (COVID-19) outbreak caused major interruptions to the entire healthcare network affecting referral, diagnosis and treatment pathways with the potential to affect cancer treatment outcomes. In Ireland a national lockdown was initiated in March 2020 involving a stay-at-home order with a limitation on travel, social interactions and closure of schools, universities and childcare facilities. We designed a retrospective study comparing treatment outcomes for patients with oropharyngeal cancer treated before and during the COVID pandemic.
