An audit of adult tetanus immunity.

Many Canadian adults are not protected against tetanus. This study examined adult patients' knowledge of their tetanus immunization and its documentation in family practice charts at a downtown teaching community health centre. A date of previous immunization was recalled by 38% (49/129) of patients. Immunization was documented on 34% (44/129) of the "cumulative patient profiles." Of the 22 patients who provided a recall date and whose charts documented immunization, 82% (18/22) had accurate recall. Written immunization records were kept by 19% (25/129) of patients. The results indicate problems both with patients' knowledge of immune status and with chart documentation by physicians. Recommendations for improvement of the immunization process are outlined.
