Acidentes com material biológico entre profissionais de saúde no Brasil<i>: </i>estudo transversal envolvendo administração medicamentosa

Background and Objectives: Healthcare professionals, particularly nursing technicians, are frequently exposed to occupational risks involving contaminated biological materials, such as blood, increasing their vulnerability to infections like HIV and hepatitis B and C. This study aimed to analyze the association between biological material exposure during medication administration among nursing technicians, compared to other healthcare professionals. Methods: A cross-sectional analytical study was conducted using 69.129 work-related accident notifications recorded in the SINAN database in 2022. Sociodemographic and clinical variables were analyzed. The association measure used was the Prevalence Ratio (PR), with 95% Confidence Interval (CI) and p ≤ 0.05. Results: Most affected individuals were aged 26 to 45 years (61.3%) and female (76.9%). Blood was the main biological material involved (74.7%). Nursing technicians showed a 2.54 times higher prevalence of accidents during medication administration compared to other professionals (PR = 2.54; 95% CI: 2.46–2.62; p < 0.0001). The Southeast region of Brazil reported the highest number of cases. Although 84.8% were vaccinated against hepatitis B, underreporting remains a concern, with 30.4% of Work Accident Reports (WAR) not issued. Conclusion: The high frequency of accidents among nursing technicians highlights the urgent need for public policies focused on prevention, improved reporting practices, and proper use of personal protective equipment (PPE). Underreporting compromises health surveillance and calls for educational and organizational strategies to enhance workplace safety in healthcare settings.
