Table 3 Endpoints

From: Upscaling cervical cancer screening and treatment for women living with HIV at a rural referral hospital in Tanzania: protocol of a before-and-after study exploring HPV testing and novel diagnostics

 

Endpoint

HPV prevalence & persistence

Proportion of participants with documented HR-HPV, LR-HPV and HPV negative at baseline

HPV genotypes at baseline

Proportion of participants with documented HR-HPV, LR-HPV and HPV negative at follow up (6 months after the first sample)

HPV genotypes at follow up (6 months after the first sample)

Rate of clearance and persistence of HPV at 6 months follow-up and factors associated with viral persistence

Cervical lesions

Prevalence of cervical dysplasia among the patients with HR-HPV

Prevalence of co-infection (STI and GS)

QG-MPH® performance

Prevalence of HSIL/CC detected by QG-MPH® in cervical smear samples

Diagnostic test accuracy (sensitivity, specificity, PPV, NPV) in detecting patients with CIN3 + compared to colposcopy images, HPV infection detected by Seegene Anyplex ™ II 28 and histology

Prevo-check® performance

Prevalence of HPV16 positive CIN2 + detected by Prevo-check®

Diagnostic test accuracy (sensitivity, specificity, PPV, NPV) in detecting patients with HPV 16 compared to Seegene Anyplex â„¢ II 28

PT Monitor® performance

Comparison of HPV16-antibody levels in women with and without HPV16-positive CIN2 + . Calculation of test performance parameters (sensitivity, specificity, PPV, NPV) at different antibody thresholds and calculation of optimum cut-off for CIN2 + detection by ROC analysis and Youden index

Diagnostic test accuracies (sensitivity, specificity, PPV, NPV) in detecting patients with HPV16-induced CIN2 + by PT Monitor® compared to colposcopy images, HPV infection detected by Seegene Anyplex ™ II HPV 28 Detection and histology

Screening strategy implementation

Acceptability of cervical self-sampling

Acceptability of proposed implemented pathway

Adherence to follow-up

Rate of WLWH completing the CC screening and treatment care plan

Prevalence of cryo/thermoablation-non-eligible lesions treated with LEEP

Service accessibility (means of travel to the point of screening: foot, car bajaj, public transport bus; distance to hospital < 5 km, 5—10 km, > 10 km, perceived difficulty of travel yes/no; mean of waiting time in minutes at point of screening)

Social and educational status of WLWH attending and refusing CC screening as well as their awareness regarding HPV infection, transmission, risk behavior, CC

Costs

Direct and indirect costs associated with CC screening and treatment before and after the proposed implementation was adopted including the bundle of interventions

Direct and indirect costs, as well visit durations, for the current VIA and cryotherapy standard of care and for the implemented path with HPV-based triage
