Confidence in Medical Device Calibration Knowledge and Skills Among Healthcare Professionals in Ghana: A...

Calibration of medical devices is vital for diagnostic reliability, quality healthcare delivery and patient safety. While awareness is critical, the confidence of healthcare professionals (HCPs) in calibration-related knowledge significantly influences adherence to best practices in calibration-related tasks. However, this area is underexplored in sub-Saharan Africa.

This study aimed to assess the confidence levels of HCPs in Ghana regarding their calibration-related knowledge and competencies. It examined how these vary by professional role, training status, and years of experience.

A cross-sectional survey was conducted among 461 HCPs in Ghana, including doctors, nurses, midwives and technicians/clinical engineers, using a structured questionnaire covering five thematic areas: general understanding of calibration knowledge, knowledge of calibration procedures, device-specific knowledge, training and institutional support, and the perceived impact on patient care.

Statistical analyses revealed variations in sentiment scores across profession, experience levels and training status. Technicians/clinical engineers consistently reported higher confidence, while doctors, nurses and midwives scored significantly lower. Additionally, respondents with prior calibration training, regardless of experience level, showed substantially greater confidence than their untrained counterparts.

These findings demonstrate the need for targeted, hands-on calibration training and continuous professional development to improve confidence and competencies in calibration practices. Such initiatives are essential for effective device management and overall healthcare system performance. This study offers evidence to guide policy improvements and capacity-building efforts to strengthen calibration knowledge and practices in Ghana's healthcare sector.
