Quality, access, and clinical issues in a nurse practitioner colposcopy outreach program

Area of Science:

• Gynecology
• Public Health
• Oncology

Background:

• Cervical cancer screening is crucial for early detection and prevention.
• Rural and medically indigent populations often face barriers to accessing specialized healthcare services.
• Portable outreach programs can extend diagnostic capabilities to underserved communities.

Purpose of the Study:

• To evaluate the effectiveness of a portable colposcopy outreach program in diagnosing cervical abnormalities.
• To determine the prevalence of human papillomavirus (HPV) and cervical intraepithelial neoplasia (CIN) in a rural, medically indigent population.
• To identify risk factors associated with cervical abnormalities in the studied population.

Main Methods:

• A NP-colposcopist performed 593 colposcopy examinations, including biopsies, endocervical curettages, and Pap smears.
• Procedures were conducted in selected health departments in north-central Florida between August 1989 and July 1992.
• Specimen results were analyzed using the Bethesda system, with a focus on HPV, CIN, carcinoma in situ (CIS), and invasive carcinoma.

Main Results:

• High prevalence of cervical abnormalities: 21.1% negative, 5.6% HPV only, 37.3% CIN I, 17.4% CIN II, 11.9% CIN III, 2.4% CIS, 0.3% carcinoma.
• Overall HPV incidence was 62.7%, with 42.8% low-grade and 32.1% high-grade lesions.
• Colposcopic diagnostic acumen was 87.7%, with one-third of undercalls attributed to occult canal lesions. Significant risk factors included smoking, early age at first coitus, HPV history, and multiple sexual partners.

Conclusions:

• Portable colposcopy outreach effectively diagnosed significant rates of cervical abnormalities in a rural, medically indigent population.
• High HPV and CIN prevalence underscore the need for targeted screening in underserved areas.
• Identified risk factors provide targets for public health interventions and prevention strategies.
