Quality of ischemic stroke care in emerging countries: the Argentinian National Stroke Registry (ReNACer)

Abstract

Background and purpose: Limited information is available on stroke management in developing countries. An accurate monitoring of quality of stroke care will become crucial, particularly with the emerging paradigm of pay-for-performance. Our aim was to explore the feasibility of measuring standardized indicators of quality of ischemic stroke care in acute care facilities in Argentina.

Methods: ReNACer is a prospective, multicenter, countrywide, stroke registry comprising 74 academic and nonacademic institutions in Argentina. The registry includes patient-level information on demography, clinical characteristics, diagnostic procedures, treatment, and the selected key performance indicators of quality of ischemic stroke care (access to thrombolysis or aspirin use in the acute setting, admission to designated stroke units, length of stay, risk-adjusted in-hospital pneumonia, risk-adjusted in-hospital mortality, discharge on antithrombotics, and antihypertensive agents).

Results: We included 1991 patients with ischemic stroke from 74 institutions in Argentina between November 2004 and October 2006. Seventy-nine per cent of the patients were prescribed antithrombotic therapy within 48 hours of admission, but only 1% received thrombolytics. No more than 5.7% were admitted to stroke units. In-hospital pneumonia was diagnosed in 14.3% of the patients and was higher in nonacademic facilities (16.4% versus 11.4%, P<0.02). The overall adjusted in-hospital mortality was 9.1%, also higher in nonacademic hospitals (10.6% versus 7.1%, P<0.008). At discharge, antithrombotics were prescribed in 90.2% and antihypertensive agents in 63.6% of the patients.

Conclusions: In ReNACer, there was a limited access to stroke units and thrombolytics, and a relatively high incidence of in-hospital pneumonia. Differences in stroke care were observed between academic and nonacademic institutions. There is an urgent need to develop national stroke programs in Argentina.
