RESUMEN
Inappropriate healthcare waste management (HCWM) may lead to health hazards through the release of toxic and infectious agents into the environment. This study aimed to assess the appropriateness of a Health Action Model (HAM) operationalized in a training intervention to promote behavioral intent towards HCWM practice among hospital staff. This was a quasi-experimental intervention study of 128 hospital staff attending a training intervention in Sabzevar Hospital, Iran. Four training intervention was carried out using potential constructs of the HAM model to compare the quality of HCWM process and behavioral intent of hospital staff before and after a training session. A questionnaire based on HAM and multiple statistical analyses were used to assess the effectiveness of the training intervention. The average age of the eligible participants was 35.05 ± 9.4 years. A majority of the participant was married (88%), nursing staff (54%) and possessed a bachelor's degree (66%) or diploma (18%). After the intervention, a significant change (p < 0.05) was observed in the intervention group compared to the control group in staff knowledge, attitude, self-efficacy, belief, and motivation. Further, our result showed a significant improvement from 53.6 ± 24.3 to 83.6 ± 11.5 in the behavioral intention toward HCWM practice. This work provides evidence of the effectiveness of the HAM as a guide in which the potential determinates that influence an individual's behavioral intention toward medical waste practice were identified and described. This model help promote behavioral intention at a variety of target audiences and setting in waste management practice.
