Optimal Strategy for the Management of ASCUS Cytology in Health Care Services of Medellin, Colombia

Cumulative Number of Participants Diagnosed by a Panel of External Experts With Cervical Intraepithelial Neoplasia Grade 2 or Higher (CIN2+): "Reviewed CIN2+"

Cumulative Cervical Intraepithelial Neoplasia Grade 2 or higher (CIN2+) diagnosed by a panel of external experts obtained after histological review of biopsies emitted by the community pathologists. Biopsies obtained during the two years of follow-up and the exit visit were reviewed by a panel of two external experts and a final result was adjudicated to each participant based on the panel of experts and the community of pathologists. This outcome is used for the effectiveness analysis of the three strategies.

Time frame: Two years since the enrolment to the exit visit (inclusive)

Number of Participants Diagnosed by a Panel of External Experts With Cervical Intraepithelial Neoplasia Grade 2 or Higher (CIN2+) at the Exit Visit, Two Years After the Enrolment: "Exit-reviewed CIN2+"

Cervical Intraepithelial Neoplasia Grade 2 or higher (CIN2+) diagnosed by a panel of external experts after reviewing biopsies collected at the exit visit, two years after the enrolment. This outcome is an estimate of the remaining disease that was not detected by the strategies during the 2 years of follow-up. The outcome was obtained after the review of all the biopsies taken during the exit visit. Biopsies were taken using a standardized research protocol to ensure the completeness of the remaining disease. Basically, all women attending the exit visit were tested with HPV testing and Pap and referred to colposcopy if any HPV positive or abnormal cytology. The colposcopy was performed by a researcher of the study team who took up to two biopsies from the observed lesion plus one or two at random if none lesion was observed. All biopsies were reviewed by the external panel. This outcome is used for the efficiency analysis of the three strategies.

Time frame: Exit visit (two years after the enrolment)

Number of Clinical Records (Cytologies, Colposcopies, and Histologies): "Health Care Utilization"

The outcome is defined as the number of cytologies, colposcopies, and histologies routinely performed during the two years of follow-up. Records were identified in databases or manually searched from clinical records. This outcome will be used for the analysis of the efficiency of the three strategies.

Time frame: Two years since the enrolment to before the exit visit (i.e., excluding clinical records collected at the exit visit)

Self-esteem

Self-esteem corresponds to the self-assessment of a positive or negative evaluation toward oneself. This outcome was measured using the Rosenberg Scale through 10 Likert-type questions with scores varying between 1 and 4 (1=strongly agree, 2=agree, 3=disagree, 4=strongly disagree). Total values range between 10 and 40 where lower scores suggest lower self-esteem. This outcome was measured at the enrollment visit, between two weeks and two months after receiving the triage result, and after one year of receiving the triage result.

Time frame: Two years between the enrolment and the exit visit

Trait Anxiety

Trait anxiety refers to the sustainable tendency to experience negative emotions (such as fears, worries, and anxiety) in various situations. This outcome was measured using the Spielberger State-Trait-Anxiety Inventory (STAI) through 20 Likert-type questions with scores varying between 0 and 3 (0=not at all, 1=somewhat, 2=moderately, 3=very much). Total values range between 0 and 60 where higher scores suggest higher levels of anxiety. This outcome was measured at the enrollment visit, between two weeks and two months after receiving the triage result, and after one year of receiving the triage result.

Time frame: Two years between the enrolment and the exit visit

State Anxiety

State anxiety refers to the transitory tendency to experience negative emotions (such as fears, worries, and anxiety). This outcome was measured using the Spielberger State-Trait-Anxiety Inventory (STAI) through 20 Likert-type questions with scores varying between 0 and 3 (0=not at all, 1=somewhat, 2=moderately, 3=very much). Total values range between 0 and 60 where higher scores suggest higher levels of anxiety. This outcome was measured at the enrollment visit, between two weeks and two months after receiving the triage result, and after one year of receiving the triage result.

Time frame: Two years between the enrolment and the exit visit

Concerns About Fertility, Cancer, and Gynecological Health

This outcome was measured using the HPV Impact Profile (HIP) scale through the following five domains: concerns about cancer and loss of fertility; emotional impact (depression and anxiety); self-image; interaction with the medical staff (pain or discomfort during the visit); and impact upon the life and its control. The response to each domain was measured on a scale from 0 to 10 (0=not at all, 1-3=a little, 4-6=somewhat, 7-9=a great deal, 10=extremely) and was then transformed to a scale from 0 to 100. A total score was calculated by adding all the items. Values \<40 indicate no or little impact, between 40 and 70 moderate impact, and \>70 indicate high psychosocial impact. This outcome was measured at the enrollment visit, between two weeks and two months after receiving the triage result, and after one year of receiving the triage result.

Time frame: Two years between the enrolment and the exit visit
