Registered outcomes7
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Mosquito Species Identification Accuracy | From the beginning of the steady stage (6 months) up to 12 months | Accuracy of mosquito species classification by VectorCam compared to molecular or sequencing results. For each taxonomic class, sensitivity, specificity, positive predictive value (PPV), and overall accuracy were calculated. A weighted F1 score accounting for class imbalance across taxa was additionally reported to provide an aggregate performance measure across species groups. |
| Primary | Throughput Efficiency (Per-specimen identification time ) | From the beginning of the steady stage (6 months) up to 12 months | Operational throughput was defined as the time required to progress from identification of one mosquito specimen to identification of the subsequent specimen under routine operating conditions. |
| Primary | Completeness (proportion of required surveillance reporting fields successfully captured and available) | From the beginning of the steady stage (6 months) up to 12 months | Data completeness was defined as the proportion of required surveillance reporting fields that were successfully captured and available for review within each arm's reporting system. For each routine surveillance data element captured on the paper-based VHT forms and subsequently entered into DHIS2, the corresponding field, if any, collected by the VectorCam application was identified, and vice versa. Data elements that existed in only one system, or that could not be mapped to an equivalent field in the other, were excluded from the completeness comparison; only fields common to both arms were retained. |
| Primary | Timeliness (delay between field specimen collection and availability of surveillance data) | From the beginning of the steady stage (6 months) up to 12 months | Timeliness was defined as the elapsed time between surveillance activity and availability of the resulting record in the arm-specific digital reporting system. In the control arm, reporting delay was calculated as the number of days between the field collection date recorded by the VHT and the date on which the corresponding surveillance record became available in Uganda's DHIS2 system. In the study arm, reporting delay was calculated from initiation of the VectorCam imaging session to successful upload of the corresponding record to the secure VectorCam cloud server. |
| Secondary | Classification performance accuracy for mosquito sex | From the beginning of the steady stage (6 months) up to 12 months | In the VectorCam (study) arm, classification of sex will be compared against morphological identification by trained VCOs under light microscopy for a subset of specimens. Performance will be measured as accuracy: the proportion of specimens correctly classified. For sex, accuracy will be reported overall and separately for females and males. |
| Secondary | Classification performance accuracy for mosquito abdominal status | From the beginning of the steady stage (6 months) up to 12 months | In the VectorCam (study) arm, classification of abdominal status will be compared against morphological identification by trained VCOs under light microscopy for a subset of specimens. Performance will be measured as accuracy: the proportion of specimens correctly classified.. Abdominal status, will be reported overall and for each category (unfed, fed, and gravid). |
| Secondary | Summative Usability Assessment (SUS Scale) | 12 months | The SUS questionnaire was administered to all participating VHTs assigned to the intervention arm. Responses were scored according to standard SUS methodology, generating a total usability score ranging from 0 to 100. Results were analyzed descriptively to characterize perceived usability and acceptability. A System Usability Scale (SUS) score is considered good when it is above 68, with scores above 80.3 considered excellent or top-tier. |
