How do laboratory technicians perceive their role in the tuberculosis diagnostic process? A cross-sectional study among laboratory technicians in health centers of Central Java Province, Indonesia

Area of Science:

• Medical Laboratory Science
• Public Health
• Tuberculosis Diagnostics

Background:

• Pulmonary tuberculosis (TB) diagnosis relies on detecting acid-fast bacilli in respiratory specimens.
• Laboratories are critical components of healthcare systems, impacting diagnostic accuracy and patient outcomes.
• Understanding laboratory technicians' perceptions is vital for optimizing TB control programs.

Purpose of the Study:

• To assess laboratory technicians' self-perceptions, including self-efficacy, role perception, and perceived resources.
• To evaluate the relationship between technicians' knowledge, attitudes, and work performance in TB diagnostics.
• To identify factors influencing laboratory technician performance in TB detection.

Main Methods:

• A cross-sectional quantitative study was conducted with 120 laboratory technicians in Central Java.
• Data were collected through interviews and observations to measure performance and work-related variables.
• Key variables included perceived self-efficacy, role, equipment availability, procedures, rewards, and knowledge.

Main Results:

• 43.3% of technicians demonstrated fairly good performance, adhering to 50%-75% of standard procedures.
• Perceived role, self-efficacy, and knowledge of procedures significantly correlated with performance.
• Perceived equipment availability also showed a significant correlation with performance, particularly after controlling for education.

Conclusions:

• Laboratory technicians recognize their crucial role in TB patient care and the importance of self-efficacy.
• Findings suggest a need for policies to enhance technician motivation and improve TB control.
• Addressing perceptions of role, self-efficacy, and resources can optimize laboratory performance in TB diagnostics.
