Needle stick injury prevention and sharp waste disposal are very important concerns among healthcare workers. It is a serious yet preventable occupational hazard directed to health providers in every health care setting. Education & training of healthcare workers on safe use of needles and sharp devices play an important role in injury prevention. A before and after interventional study design was used to determine improvement on the knowledge and practices on needle stick injury prevention and sharp waste disposal among healthcare workers from the 16 main health centers in Zamboanga City. During the pre-intervention period, respondents’ knowledge and practices were first assessed, the yielded results were then used as guide to conceptualize two tailored and reproducible interventions. Specifically, lecture and video were utilized as Health Education Interventions to relay basic information, related statistics, preventive measures and standard safety protocol on needle stick injury prevention and sharp waste disposal. A total of 32 respondents were divided into two groups based on the geographical location of their health centers. During the intervention phase, 16 respondents received an 11-minute video intervention while 16 other respondents received an 11-minute lecture intervention. Thereafter, the respondents’ knowledge and practices were reassessed immediately after, a week later and 1 month following the intervention phase. The study showed that the knowledge of respondents has improved from fair and good to consistently good after receiving the lecture and video interventions. Likewise, their practices have improved from fair to good at the end of the study. Comparison of the respondents’ pre-intervention and post-intervention results showed that the improvement in their knowledge (p value of 0.00) and practices (p value of 0.00-0.03) were consistently significant. However, comparison of the improved knowledge (p value of 0.54-0.91) and practices (p value of 0.24-1.00) between respondents who had lecture and those who had video only intervention, yielded no significant difference. The study concludes that, with the use of lecture and video interventions, significant improvement was noted on knowledge and practice on needle stick injury prevention and sharp waste disposal among the healthcare workers from 16 main health centers in Zamboanga City.
