Background: Many women fail to adhere to Papanicolaou smear screening guidelines. Although many interventions have been developed to increase screening, the effectiveness of different types of interventions is unclear.Methods: We performed a systematic review of interventions to increase Papanicolaou smear use published between 1980 and April 2001 and included concurrently or randomized controlled studies with defined outcomes. Interventions were classified as targeted to patients, providers, patients and providers, or health care systems and as behavioral, cognitive, sociologic, or a combination based on the expected action of the intervention. Effect sizes and 95% confidence intervals were calculated for each intervention.Results: Forty-six studies with 63 separate interventions were included. Most interventions increased Papanicolaou smear use, although in many cases the increase was not statistically significant. Behavioral interventions targeted to patients (eg, mailed or telephone reminders) increased Papanicolaou smear use by up to 18.8%; cognitive and sociologic interventions were only marginally effective, although a single culturally specific, sociologic intervention using a lay health worker increased use by 18.0% (95% confidence interval [CI]: 7.6, 28.4). Provider-targeted interventions were heterogeneous. Interventions that targeted both patients and providers did not appear to be any more effective than interventions targeted to either patients or providers alone. One of the most effective interventions, which introduced a system change by integrating a nurse-practitioner and offered same-day screening, increased screening by 32.7% (95% CI: 20.5, 44.9). Screening with regular Papanicolaou smears can decrease not only cervical cancer mortality but also the incidence of invasive disease.
Conclusions1,2 Despite increases in recent Papanicolaou smear use during the past two decades, 3,4 with national estimates of approximately 80% within the past 3 years, 4 some women still fail to adhere to recommended Papanicolaou smear screening guidelines, are found to have advanced disease, and die of invasive cervical cancer.27-29 Thus, the potential benefits of routine screening are not being fully realized. Increasing the provision of Papanicolaou smear counseling by primary care providers and, ultimately, routine Papanicolaou smear use are important components of current Healthy People 2010 goals for reducing cervical cancer mortality.
30Physician recommendation is one of the strongest predictors of screening use, 13,17,[31][32][33][34][35][36][37] but in many cases, women report that their provider did not recommend Papanicolaou smears. 5,7,18,38 -45 Explanations for this behavior include lack of time, busy schedules and forgetfulness, 46,47 screening efficacy in the absence of symptoms or concern about proficiency, 31,48 or confusion about conflicting professional recommendations. 46 In the absence of a physician recommendation, patients might assume that screening is unnecessary.Women who do not receiv...
