Measure
Pocket Colposcope
Pocket-Assisted Visual Inspection with Acetic Acid (PA-VIA): The cervix should be wiped with a cotton swab to remove any preexisting mucous and/or blood. A 3-5% acetic acid solution will be applied using a spray bottle or fox swab. After approximately 1-minute, using the Pocket Colposcope any changes to the cervix will be noted. Using the Calla Health image acquisition software, both white and green images of the cervix will be captured at low-resolution. High-resolution green light images will be obtained at the provider's discretion. Acetic acid may be reapplied between white and green imaging at the provider's discretion if acetowhitening diminishes.
Standard of Care (VIA)
Visual Inspection with Acetic Acid (VIA): First, the cervix should be wiped with a cotton swab to remove any preexisting mucous and/or blood. A 3-5% acetic acid solution will be applied to the cervix using a spray bottle or fox swab. After approximately 1-minute, any changes to the cervix using the naked eye will be noted. Acetic acid may be reapplied if acetowhitening diminishes during visual inspection.

Questionnaire data were not collected for the two mis-weighted randomization arms due to a lengthy enrollment pause prior to those arms being enrolled, as well as the randomization error. No data were collected from participants in the mis-weighted randomization arms, and there is no data to report.

Participants were asked how much they knew about cervical cancer and cervical cancer prevention prior to the exam and after the visit.

Questionnaire data were not collected for the two mis-weighted randomization arms due to a lengthy enrollment pause prior to those arms being enrolled, as well as the randomization error. No data were collected from participants in the mis-weighted randomization arms, and there is no data to report.

Participant perspective of the exam was assessed by asking "How confident are you in the provider's assessment from today's visit?"

Outcome measures

Outcome measures
Measure
Pocket Colposcope
n=190 Participants
Pocket-Assisted Visual Inspection with Acetic Acid (PA-VIA): The cervix should be wiped with a cotton swab to remove any preexisting mucous and/or blood. A 3-5% acetic acid solution will be applied using a spray bottle or fox swab. After approximately 1-minute, using the Pocket Colposcope any changes to the cervix will be noted. Using the Calla Health image acquisition software, both white and green images of the cervix will be captured at low-resolution. High-resolution green light images will be obtained at the provider's discretion. Acetic acid may be reapplied between white and green imaging at the provider's discretion if acetowhitening diminishes.
Standard of Care (VIA)
n=197 Participants
Visual Inspection with Acetic Acid (VIA): First, the cervix should be wiped with a cotton swab to remove any preexisting mucous and/or blood. A 3-5% acetic acid solution will be applied to the cervix using a spray bottle or fox swab. After approximately 1-minute, any changes to the cervix using the naked eye will be noted. Acetic acid may be reapplied if acetowhitening diminishes during visual inspection.
Mis-weighted Randomization to Pocket Colposcope
Pocket-Assisted Visual Inspection with Acetic Acid (PA-VIA): The cervix should be wiped with a cotton swab to remove any preexisting mucous and/or blood. A 3-5% acetic acid solution will be applied using a spray bottle or fox swab. After approximately 1-minute, using the Pocket Colposcope any changes to the cervix will be noted.

SECONDARY outcome

Timeframe: Baseline

Population: Participants who completed the questionnaire. Questionnaire data were not collected for the two mis-weighted randomization arms due to a lengthy enrollment pause prior to those arms being enrolled, as well as the randomization error. No data were collected from participants in the mis-weighted randomization arms, and there is no data to report.

Participant perspective of the exam was assessed by asking "How likely would you recommend this medical exam to a friend?"
