||Epidemiological approaches to the study of episodic health events are reviewed. Episodic events are defined as events that occur suddenly or that suddenly cross a threshold, but with onsets at distinct points in time. Studying such health events poses four challenges to existing methods: key epidemiological concepts, such as incidence, do not naturally accommodate recurrent events; study designs must capture time-varying exposures; statistical models must be able to handle correlated outcomes; and feedback bias must be addressed. In response, methods such as longitudinal studies, case-crossover designs and generalized estimating equations are identified as appropriate tools.
