Methods: The design of questionnaire was based on TPB and the literature of patient safety. The researchers adopt the purposeful sampling approach. Three hospital systems in Taiwan were selected. Totally, 2,565 questionnaires were distributed and 2,151 were collected. The response rate was 81.2%.
Results: 53.8% participants had incidents reporting experiences. The average time of completing reporting by entering data was 21.67 minutes. Then, learning how to use the reporting system averagely took 17.9 minutes. There was no significance among three hospital systems in terms of incidents reporting intention by using ANOVA test. However, there were significantly different between variables(p<.01). The study found that the nurses' reporting intention of medical incidents was affected by the attitude and behaviour beliefs, self control, and the main reference groups.
Conclusions: The internalization of value of medical incidents reporting and the formulation of its culture would contribute to the reporting of medical incidents. The willpower control of reporters played a pivotal role of reporting incidents. Especially, the unit supervisor, colleagues in the same unit, colleagues having reporting experiences, and the same event another party were important reference groups of reporting behaviour norm.
