Williams, Division of Child Health, Department of Infection, Immunity and Inflammation, University of Leicester, Robert Kilpatrick Building, Leicester Royal Infirmary, LE2 7LX, UKPurpose: To determine the extent and reasons for delay in accessing specialist eye care following a significant eye injury.Methods: Mixed methods study involving 93 consecutive admissions to Kilimanjaro Christian Medical Center, Tanzania (KCMC). Semi-structured interviews were conducted and supplemented by a review of medical notes. A statistical analysis of delay and predictor variables was conducted. Framework analysis of interviews was conducted.Results: Ninety of 93 patients took part. Significant visual loss was determined in 95.5% of affected eyes on arrival. The mean delay for treatment was 6.8 days. Of participants, 61.1% visited some health facility within 24 hours, and 82.2% within 48 hours. Injury on a weekend, using topical drops and visiting other health facilities before KCMC were independently associated with delay greater than 24 hours and greater than 48 hours, female gender with was associated with delay greater than 24 hours. Patient journeys involved key milestones and processes. Journeys were frequently “circular,” involving delays caused by repeated visits to health units unable to treat the injury, often on a health worker’s advice. Systems problems included unclear referral systems and opening times, frequent staff absence and unqualified staff deputizing. Individual health workers had an important influence on delay but their performance appeared variable. They influenced patient journeys positively when they made an accurate diagnosis, referred directly to KCMC, discussed practicalities and communicated the seriousness of the injury, the need for urgent treatment and the adverse consequences of delay.Conclusions: There is significant delay in accessing appropriate specialist care following eye injury in Tanzania, much of which occurs after first visiting a health facility. We present a new model of delay that may help guide interventions to reduce this delay.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
