Interventions to increase cervical cancer screening rates.

Evidence-Based Answer Invitation letters are the most studied method of encouraging cervical cancer screening, and they are effective (relative risk [RR] = 1.44; 95% confidence interval [CI], 1.24 to 1.52).1-3 Invitation letters may be more cost-effective than more intensive recruitment efforts (e.g., telephone interviews, promotional campaigns). Other educational interventions (e.g., other types of invitations, reminders, counseling) also increase screening rates, but it is unclear which interventions are most effective.1 (Strength of Recommendation: B, based on inconsistent or limited-quality patient-oriented evidence.)
