  1. Approaches to the problems of measuring the incidence of stroke : the Auckland Stroke Study, 1991-1992.

    Article - En anglais

    This paper highlights some of the problems likely to be encountered in this endeavour by describing the experience of measuring acute stroke prospectively.

    Methods

    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.

    Results

    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.

    Conclusions

    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.
