Control of nosocomial tuberculosis in New Zealand: a window into hospital occupational health?

A survey of six New Zealand hospitals, each of which employs at least one respiratory physician, demonstrated lack of uniformity and several deficiencies in measures to prevent nosocomial tuberculosis. Preemployment screening measures in particular were frequently suboptimal. Suggested improvements include upgrading tuberculosis control policies at a national level, with input from hospital boards, clinicians, and the Department of Health. Future policy changes should be based upon local and national experience and this requires the auditing of hospital control measures. The number of health workers amongst new cases of tuberculosis should also be recorded and taken into account.
