Objective
The objective of this study was to assess the conditions under which Zambia
women with a history of cervical cancer screening by visual inspection with acetic acid
might switch to HPV-based testing in the future.
Methods
We conducted a choice-based conjoint survey in a sample of women recently
screened by visual inspection in Lusaka, Zambia. The screening attributes considered in
hypothetical choice scenarios included: screening modality, sex and age of the examiner,
whether screening results would be presented visually, distance from home to the clinic,
and wait time for results.
Results
Of 238 women in the sample, 208 (87.4%) provided responses sufficiently
reliable for analysis. Laboratory testing on a urine sample was the preferred screening
modality, followed by visual screening, laboratory testing on a self-collected vaginal
specimen, and laboratory testing on a nurse-collected cervical specimen. Market
simulation suggested that only 39.7% (95% confidence interval, 33.8, 45.6) of
respondents would prefer urine testing offered by a female nurse in her 30's over visual
inspection of the cervix conducted by a male nurse in his 20's if extra wait time were
as short as one hour and the option of viewing how their cervix looks like were not
available.
Conclusion
Our study suggests that, for some women, level of preference for HPV-based
screening strategies may depend highly on the process and conditions of service
delivery.
