back Factors associated with physician interventions to address adolescent smoking T H Sims Objective: To determine the percent of adolescent Medicaid patients with medical record documentation about tobacco use status and cessation assistance; and factors associated with providers documenting and intervening with adolescent smokers. Data Source: Secondary analysis of data collected in 1999 from medical records of Wisconsin Medicaid Health Maintenance Organization recipients 11 to 21 year olds. Study Design: Random reviews and data collection were related to visits from January 1997 to January 1999. Data collected included: patient demographics, provider type, number of visits, whether smoking status and cessation interventions were documented. Data Extraction Methods: Medical charts were reviewed and a database created using a data abstraction tool developed and approved by a committee to address tobacco use in Medicaid managed care participants. Principal Findings: Among adolescents seen by a physician from 1997 to 1999, tobacco use status was documented in 55% of patient charts. Most often tobacco use status was documented on history and physical or prenatal forms. Of identified adolescent smokers, 50% were advised to quit, 42% assisted, and 16% followed for smoking cessation. Pregnant patients were more likely to have tobacco use documented than nonpregnant patients (O.R.=10.8, 95% CI= 4.9 to 24). The odds of documentation increased 21% for every year increase in patient age. Conclusions: Providers miss opportunities to intervene with adolescents who may be using tobacco. Medical record prompts, similar to the tobacco use question on prenatal forms and the tobacco use vital sign stamp, are essential for reminding providers to consistently document and address tobacco use among adolescents.
