Approaches to the problems of measuring the incidence of stroke : the Auckland Stroke Study, 1991-1992.
This paper highlights some of the problems likely to be encountered in this endeavour by describing the experience of measuring acute stroke prospectively.
The Auckland Stroke Study is a community-based study among 945 000 residents of the Auckland region, New Zealand.
Standard definitions and overlapping case-finding methods were used to identify all new acute stroke events occurring during the 12-month period ending 1 March 1992.
Particular attention was directed at including non-fatal strokes managed outside hospital.
The latter were identified by use of a cluster sample, a technique suitable for populations where residents have a personal primary health care physician.
The comprehensive sources of referral to the study involved the review of 5736 records, less than one-third of which met the criteria for inclusion.
The majority of included acute stroke events (n=1803) were found through routinely available sources such as hospital admission records (63%) and death registrations (10%). The remainder (27%) were identified through intensive efforts at case-finding of stroke events managed outside hospital.
While time-consuming, costly and demanding, there appears to be no easier alternative to a register to estimate incidence.
This study demonstrates the importance of the use of comprehensive case-finding sources and suggests approaches to overcoming the difficulties in monitoring stroke incidence in large populations.
