Stroke is a major health concern throughout Latin America. As elsewhere, no precise cause can be determined for a substantial portion of strokes. In 6 studies since 2010 in the region, 16% to 43% of ischemic strokes were identified as cryptogenic. The term embolic stroke of undetermined source (ESUS) has been proposed as more clinically useful and positively defined than the vague term cryptogenic. The epidemiology of ESUS in Latin America is largely unknown.

Review of the medical necessity of hospital or other health facility admissions, upon or within a short time following an admission, and periodic review of services provided during the course of treatment.
Formal programs for assessing drug prescription against some standard. Drug utilization review may consider clinical appropriateness, cost effectiveness, and, in some cases, outcomes. Review is usually retrospective, but some analysis may be done before drugs are dispensed (as in computer systems which advise physicians when prescriptions are entered). Drug utilization review is mandated for Medicaid programs beginning in 1993.
Brief reversible episodes of focal, nonconvulsive ischemic dysfunction of the brain having a duration of less than 24 hours, and usually less than one hour, caused by transient thrombotic or embolic blood vessel occlusion or stenosis. Events may be classified by arterial distribution, temporal pattern, or etiology (e.g., embolic vs. thrombotic). (From Adams et al., Principles of Neurology, 6th ed, pp814-6)
