Objective: To evaluate the effectiveness of a standardized hazardous medication surveillance program and identify occupational factors associated with adverse health outcomes among healthcare workers (HCWs). Methods: We analyzed data from 2,625 HCWs enrolled in a multi-site surveillance program (2020–2022). Participants completed a standardized questionnaire and underwent complete blood count testing. Exposure was categorized by weekly time handling hazardous medications. Associations were evaluated using univariate and multivariable analyses. Results: Higher exposure (>8 hours/week) was associated with increased symptom reporting, hazardous medication spills, and adverse reproductive outcomes. Female sex, older age, and spill exposure independently predicted symptom reporting and reproductive outcomes. No significant association was observed between exposure intensity and abnormal blood counts. Conclusion: Questionnaire-based surveillance effectively identified exposure-related health risks, whereas routine complete blood count testing showed limited utility.

Abstract Background US public health strategy for eliminating tuberculosis (TB) prioritizes treatment of latent TB infection (LTBI). Healthcare personnel (HCP) are less willing to accept treatment than other populations. Little is known about factors associated with HCP LTBI therapy acceptance and completion. Methods We conducted a retrospective chart review to identify all employees with LTBI at time of hire at a large academic medical center during a 10-year period. Personal demographics, occupational factors, and clinic visit variables were correlated with LTBI treatment acceptance and completion rates using multivariate logistic regression. Results Of 470 HCP with LTBI for whom treatment was recommended, 193 (41.1%) accepted treatment, while 137 (29.1%) completed treatment. Treatment adherence was better with 4 months of rifampin than 9 months of isoniazid (95% vs 68%, P < .005). Increased age of the healthcare worker was independently associated with lower rates of treatment acceptance (odds ratio [95% confidence interval]: 0.97 [0.94–0.99] per year), as was having an occupation of clinician (0.47 [0.26–0.85]) or researcher (0.34 [0.19–0.64]). Male gender was associated with higher treatment acceptance (1.90 [1.21–2.99]). Treatment completion was associated with being from a low- (9.49 [2.06–43.73]) or medium- (8.51 [3.93–18.44]) TB-burden country. Conclusions Geographic and occupational factors affect acceptance and completion of LTBI therapy. Short-course regimens may improve adherence. Physicians, researchers, and HCP from high-TB-burden countries have lower treatment rates than other HCP. Improving LTBI treatment in HCP will require attending to cultural and occupational differences.
