Objective:
To determine women's acceptance of fluorescent and reflective spectroscopy (FRS) as a potential replacement test for the Pap smear.
Materials And Methods:
Women scheduled for a colposcopic examination, or a colposcopic and FRS examination, completed a 22-item questionnaire that included demographic data, medical history, and preference-type questions. Data were compared using chi and Wilcoxon's rank sum tests.
Results:
Women considered accuracy, comfort, and quick results to be the most important characteristics for new cervical cancer tests. Immediate test results were preferred strongly by both groups (control, 84.5%; scanned, 88.6%). Provided FRS was more accurate than the Pap smear, most women (control, 74.7%; scanned, 68.2%) would rather have FRS if it cost the same as a Pap smear.
Conclusions:
Women consider accuracy, comfort, and time critical issues with respect to FRS used as a primary screening test. Acceptance of this new technology will be facilitated by designing equipment accordingly to satisfy the concerns of women.
