Dry-Cleaning Chemicals and a Cluster of Parkinson's Disease and Cancer: A Retrospective Investigation.

BACKGROUND: Environmental exposure to trichloroethylene (TCE), a carcinogenic dry-cleaning chemical, may be linked to Parkinson's disease (PD). OBJECTIVE: The objective of this study was to determine whether PD and cancer were elevated among attorneys who worked near a contaminated site. METHODS: We surveyed and evaluated attorneys with possible exposure and assessed a comparison group. RESULTS: Seventy-nine of 82 attorneys (96.3%; mean [SD] age: 69.5 [11.4] years; 89.9% men) completed at least one phase of the study. For comparison, 75 lawyers (64.9 [10.2] years; 65.3% men) underwent clinical evaluations. Four (5.1%) of them who worked near the polluted site reported PD, more than expected based on age and sex (1.7%; P = 0.01) but not significantly higher than the comparison group (n = 1 [1.3%]; P = 0.37). Fifteen (19.0%), compared to four in the comparison group (5.3%; P = 0.049), had a TCE-related cancer. CONCLUSIONS: In a retrospective study, diagnoses of PD and TCE-related cancers appeared to be elevated among attorneys who worked next to a contaminated dry-cleaning site. © 2024 The Authors.

Predictors of faculty narrative evaluation quality in medical school clerkships.

INTRODUCTION: Narrative approaches to assessment provide meaningful and valid representations of trainee performance. Yet, narratives are frequently perceived as vague, nonspecific and low quality. To date, there is little research examining factors associated with narrative evaluation quality, particularly in undergraduate medical education. The purpose of this study was to examine associations of faculty- and student-level characteristics with the quality of faculty member's narrative evaluations of clerkship students. METHODS: The authors reviewed faculty narrative evaluations of 50 students' clinical performance in their inpatient medicine and neurology clerkships, resulting in 165 and 87 unique evaluations in the respective clerkships. The authors evaluated narrative quality using the Narrative Evaluation Quality Instrument (NEQI). The authors used linear mixed effects modelling to predict total NEQI score. Explanatory covariates included the following: time to evaluation completion, number of weeks spent with student, faculty total weeks on service per year, total faculty years in clinical education, student gender, faculty gender, and an interaction term between student and faculty gender. RESULTS: Significantly higher narrative evaluation quality was associated with a shorter time to evaluation completion, with NEQI scores decreasing by approximately 0.3 points every 10 days following students' rotations (p = .004). Additionally, women faculty had statistically higher quality narrative evaluations with NEQI scores 1.92 points greater than men faculty (p = .012). All other covariates were not significant. CONCLUSIONS: The quality of faculty members' narrative evaluations of medical students was associated with time to evaluation completion and faculty gender but not faculty experience in clinical education, faculty weeks on service, or the amount of time spent with students. Findings advance understanding on ways to improve the quality of narrative evaluations which are imperative given assessment models that will increase the volume and reliance on narratives.

Education Research: The Narrative Evaluation Quality Instrument: Development of a tool to assess the assessor.

OBJECTIVE: Determining the quality of narrative evaluations to assess medical student neurology clerkship performance remains a challenge. This study sought to develop a tool to comprehensively and systematically assess quality of student narrative evaluations. METHODS: The Narrative Evaluation Quality Instrument (NEQI) was created to assess several components within clerkship narrative evaluations: performance domains, specificity, and usefulness to learner. In this retrospective study, 5 investigators scored 123 narrative evaluations using the NEQI. Inter-rater reliability was estimated by calculating interclass correlation coefficients (ICC) across 615 NEQI scores. RESULTS: The average overall NEQI score was 6.4 (SD 2.9), with mean component arm scores of 2.6 for performance domains (SD 0.9), 1.8 for specificity (SD 1.1), and 2.0 for usefulness (SD 1.4). Each component arm exhibited moderate reliability: performance domains ICC 0.65 (95% confidence interval [CI] 0.58-0.72), specificity ICC 0.69 (95% CI 0.61-0.77), and usefulness ICC 0.73 (95% CI 0.66-0.80). Overall NEQI score exhibited good reliability (0.81; 95% CI 0.77-0.86). CONCLUSION: The NEQI is a novel, reliable tool to comprehensively assess the quality of narrative evaluation of neurology clerks and will enhance the study of interventions seeking to improve clerkship evaluation.
