Results of 3,009 Papanicolaou smears from black women are reviewed. The modus operandi and cost for the outpatient component are presented. Abnormal results were reported in 11.6 percent of the combined outpatients and inpatients. The major portion of the changes in this subset were due to atypia present in a substantial number of women with Trichomonas vaginalis vaginitis. Programs of this nature with a specific objective may be easily merged into the basic medical services provided by an outpatient and inpatient department.
