Evaluation of medical device calibration knowledge, perceived importance, and implementation support among healthcare professionals in Ghana

Objectives Medical device calibration underpins accuracy, precision, and reliability, which are critical to optimal device performance and quality healthcare delivery. Despite its importance, little empirical evidence exists on calibration knowledge among healthcare professionals in sub-Saharan Africa. This study assessed such knowledge in Ghana by examining familiarity with calibration principles, procedures, device-specific practices, institutional support, and factors influencing competence. Methods A cross-sectional survey of 425 healthcare workers (technicians/clinical engineers, nurses, midwives, and doctors) employed a structured questionnaire. Statistical analyses ( t -tests, ANOVA, and correlation analysis) were conducted to identify differences and associations in calibration knowledge and practices. Results Analyses revealed significant knowledge gaps. Technicians/clinical engineers outperformed other groups, while early-career professionals (1–3 years’ experience) scored higher than mid-career counterparts (7–10 years), highlighting shortcomings in continuous professional development. Formal training was also associated with higher scores. Conclusion These findings highlight the urgent need for structured, role-specific training and ongoing professional education to close calibration knowledge gaps, safeguard patient safety, and optimise device performance. The results provide evidence for policy reforms and workforce development strategies to strengthen medical device management and healthcare quality.
