Introduction-Physicians are at greater risk of air borne infection from patients. They must protect themselves from the diseases to serve the society better. There are four methods by which air borne infections can be minimized - Air Filter, Ioniser, Directed Air Flow and Air Curtain. All these methods can be used in OPD by using already available device in market in specific manner.
Method-100 patients were selected for this study. Hepa filter placed at appropriate level in between physician and patients in out-patient setting. Soap bubble spray toy used for measuring the efficiency of protection of infections from patients to physicians. Confirmation done by growth of microorganism over culture media.
Results-Negative growth of bacteria on culture media when filter in switched on suggest its effectiveness as barrier of spread of infections from patients to physicians.
Conclusions-Hepa filters were effective in prevention of infections from patients to physicians and is confirmed by negative cuture report. However more study is warranted regarding this issue and there is a need for such medical device development.
