Screening pelvic examinations in asymptomatic, average-risk adult women: an evidence report for a clinical practice guideline from the American College of Physicians.

BACKGROUND: Pelvic examination is often included in well-woman visits even when cervical cancer screening is not required.

PURPOSE: To evaluate the diagnostic accuracy, benefits, and harms of pelvic examination in asymptomatic, nonpregnant, average-risk adult women. Cervical cancer screening was not included.

DATA SOURCES: MEDLINE and Cochrane databases through January 2014 and reference lists from identified studies.

STUDY SELECTION: 52 English-language studies, 32 of which included primary data.

DATA EXTRACTION: Data were extracted on study and sample characteristics, interventions, and outcomes. Quality of the diagnostic accuracy studies was evaluated using a published instrument, and quality of the survey studies was evaluated with metrics assessing population representativeness, instrument development, and response rates.

DATA SYNTHESIS: The positive predictive value of pelvic examination for detecting ovarian cancer was less than 4% in the 2 studies that reported this metric. No studies that investigated the morbidity or mortality benefits of screening pelvic examination for any condition were identified. The percentage of women reporting pelvic examination-related pain or discomfort ranged from 11% to 60% (median, 35%; 8 studies [n = 4576]). Corresponding figures for fear, embarrassment, or anxiety ranged from 10% to 80% (median, 34%; 7 studies [n = 10 702]).

LIMITATION: Only English-language publications were included; the evidence on diagnostic accuracy, morbidity, and mortality was scant; and the studies reporting harms were generally low quality.

CONCLUSION: No data supporting the use of pelvic examination in asymptomatic, average-risk women were found. Low-quality data suggest that pelvic examinations may cause pain, discomfort, fear, anxiety, or embarrassment in about 30% of women.
