Dissociation between hospital performance of the smoking cessation counseling quality metric and cessation outcomes after myocardial infarction.
BACKGROUND: Recognizing the importance of smoking cessation after acute myocardial infarction (AMI), the Centers for Medicare & Medicaid Services and the Joint Commission on Accreditation of Healthcare Organizations currently uses documentation of smoking cessation counseling (SCC) as a metric of hospitals' quality of AMI care. Yet, the association between hospitals' performance of this quality measure and subsequent tobacco cessation rates has not been established. METHODS: We analyzed 889 consecutive smokers treated for AMI at 19 hospitals in PREMIER (Prospective Registry Evaluating Myocardial Infarction: Events and Recovery) between January 1, 2003, and June 28, 2004. Patients were followed up for 1 year after hospitalization. Multivariate regression modeling was performed to determine the association between hospital-level documented SCC rates and tobacco cessation rates after discharge. RESULTS: On a hospital level, the median medical record-documented SCC rate was 72.0% (interquartile range, 59.6%-90.1%). At 1 year, the median smoking cessation rate was 55.6% (interquartile range, 37.5%-61.9%). Although patients with documented SCC were more likely to recall receiving SCC at 1 month (86.1% vs 70.8%, P < .001), their rate of quitting at 1 year was lower than that of patients without documented SCC (50.1% vs 60.7%, P = .02; relative risk, 0.76; 95% confidence interval, 0.61-0.94). At the hospital level, there was no correlation between SCC documentation and successful quitting at 6 months (r = -0.19, P = .11) or 1 year (r = -0.13, P = .45). CONCLUSIONS: The performance metric for SCC, as it is currently structured, does not correlate with actual smoking cessation at 6 months or 1 year. Revision of this performance measure should be considered to more effectively reflect the goal of promoting smoking cessation.
