Using Interactive Software to Teach Image-Based Clinical Laboratory Tests in Developing Countries: A Pilot Trial in Nepal

This study explores the feasibility of using computer tutorials to train laboratory personnel in Nepal. Training incorporated three software programs that teach microscope-based laboratory tests (peripheral blood smears, urinalysis, Gram stains). Forty-seven participants attended training sessions and completed a questionnaire. The participants' overall perception was: 1) the software was superior to formal lectures for learning image-based laboratory tests (43 participants, 92%); 2) the software would enhance job performance (43 participants, 92%); 3) more subjects should be taught using software (40 participants, 85%); and 4) the software helped participants learn new materials (38 participants, 81%). Considering that 79% of the participants were novice computer users, it is noteworthy that 38 (81%) participants thought the method of instruction was easy to understand. Factors contributing to learning included: 1) the resemblance of the computer images to actual microscope images derived from patient samples (37 participants, 68%); 2) the use of multiple examples of cells and other microscopic structures (28 participants, 60%); 3) the ability to interact with images and animations (23 participants, 49%); 4) the step-by-step explanation of laboratory techniques (21 participants, 45%); and 5) the self-pacing of the tutorial (12 participants, 26%). Overall, the pilot study suggests that educational software could help train clinical laboratory personnel in developing countries.
