Impact of education on knowledge, attitudes and practices among various categories of health care workers on nosocomial infections.

PURPOSE

To assess the knowledge, attitudes and practices among the different health care workers (HCWs) on nosocomial infections.

METHODS

A total of 150 HCWs, doctors (n=50), nurses (n=50) and ward aides (n=50) were included. A questionnaire was administered to the HCWs to assess their knowledge, attitudes and practices on nosocomial infections. A scoring system was devised to grade those (KAP score). They were further subjected to a series of similar questionnaires at intervals of 6, 12 and 24 months after an education module. Subjects in each category of staff (n=10) were observed for compliance to hand washing practices in the ward in the post-education period. Statistical analysis was done using statistical software.

RESULTS

The study showed an increase in the number of subjects in each category scoring good and excellent in the post-education questionnaire; however this declined with the progress of time. It was observed that the compliance level to hand washing practices differed among the different HCWs. Total compliance was 63.3% and ward aides were most compliant 76.7% (adjusted Wald 95% CI= 58.80-88.48).

CONCLUSIONS

Education has a positive impact on retention of knowledge, attitudes and practices in all the categories of staff. There is a need to develop a system of continuous education for all the categories of staff. In order to reduce the incidence of nosocomial infections, compliance with interventions are mandatory.
