BACKGROUND: Clinical guidelines recommend lipid testing in all hospitalized acute myocardial infarction (AMI) patients. Inhospital lipid testing has also been proposed as a quality indicator for AMI care, but little is known about its use or importance. We sought to examine rates of inhospital lipid testing and its association with statin therapy at hospital discharge. METHODS: We performed an analysis using medical chart abstraction data that included demographic and comprehensive clinical information for patients hospitalized in Ontario, Canada, with an AMI from 1999 to 2001. RESULTS: Among 11,468 patients, inhospital lipid testing was performed in 6,019 (52.5%) patients and in 4,169 (36.4%) patients within 24 hours of admission. Patients who had lipid testing were significantly more likely to be discharged on statin therapy compared with patients not tested (41.4% vs 23.0%, P < .001). In addition, inhospital lipid testing was strongly associated (odds ratio 3.61, 95% CI 3.15-4.14) with statin therapy prescription at hospital discharge after adjusting for other clinical, physician, and hospital factors. CONCLUSIONS: Despite endorsements from practice guidelines, less than half of all admitted AMI patients received lipid testing within 24 hours of hospital admission. Because inhospital lipid testing was strongly associated with the initiation of statin therapy at discharge, many opportunities to initiate statin therapy were lost. Efforts to increase the use of lipid testing in hospitalized AMI patients may translate into higher rates of lipid-lowering therapy and improved patient outcomes.
