Reducing vision impairment in children through health system assessment and strengthening approach in Papua New Guinea.

Doctoral Degree. University of KwaZulu-Natal, Durban.ABSTRACT A strong and efficient integrated health system is able to contribute to the reduction of vision impairment among children by ensuring preventive measures are implemented and timely access to care is done in case of morbidity. Children in Papua New Guinea presenting late for congenital cataract surgery, incurring avoidable eye injuries, living with uncorrected refractive error and some presenting with advanced retinoblastoma were of concern to the researcher. The overall aim of the study was to assess how the current health system in Papua New Guinea is addressing child eye health using Port Moresby General Hospital and Goroka hospital as case studies. It is envisaged that a health strengthening approach benefits children’s eye health in the community. Methods Both quantitative and qualitative methods were employed. Retrospective medical records review of children seen at the eye clinic in Port Moresby and Goroka Hospitals from January 2015 to December 2017 was conducted. In the qualitative method service providers and caregivers were interviewed to obtain their perspectives regarding performance of the health system. Results At Port Moresby General Hospital trauma, conjunctivitis and corneal ulcers accounted for 21.6%, 18.9% and 9% respectively of all the diagnoses among children. Trauma was in the ratio of 1:1 (p= 0.264) male to female. And 7.3% (n=51) of the children were blind (according to the WHO definition). Among the blind children optic nerve disorders accounted for 20.5 %( n=14) followed by both un-operated cataracts and uncorrected refractive error each at 13.2% (n=9). Retinoblastoma presented at mean age 5.869 (SD4.5) and 6.02(SD 2.4) years for girls and boys respectively. The main causes of ocular morbidity observed at Goroka Hospital were corneal ulcers (24.9%), uveitis (9.3%) and foreign bodies (9.2%). Service provider interviews revealed lack of policy on child eye health, shortage of health personnel and limited community eye health services. But among care givers lack of eye health information in the community, concerns about long waiting time at the hospitals and inadequate explanation about conditions affecting the children featured prominently. Conclusion Findings show a higher percentage of blind children compared to similar hospital based studies elsewhere. To achieve universal eye health coverage, raising awareness about child eye health needs among leaders in health is urgent. Successes registered in the past in Papua New Guinea in other child health efforts like immunisation suggest that a consistent and focused health system strengthening approach with greater integration may contribute to reduction of vision impairment among children. A proposed child eye health strategy based on the findings from this study is included in this thesis

Burden, etiology and predictors of visual impairment among children attending Mulago National Referral Hospital eye clinic, Uganda

Background: Childhood visual impairment (CVI) has not been given due attention. Knowledge of CVI is important in planning preventive measures. The aim of this study was determine the prevalence, etiology and the factors associated with childhood visual impairment among the children attending the eye clinic in Mulago National Referral Hospital.Methods: This was a cross sectional hospital based study among 318 children attending the Mulago Hospital eye clinic between January 2015 to March 2015. Ocular and general history was taken and patient examination done. The data generated was entered by Epidata and analyzed by STATA 12.Results: The prevalence of CVI was 42.14%, 134 patients with 49 patients (15.41%) having moderate visual impairment, 45 patients (14.15%) having severe visual impairment and 40 patients (12.58%) presenting with blindness. Significant predictors included; increasing age, delayed developmental milestones and having abnormal corneal, refractive and fundus findings.Conclusion: There is a high burden of visual impairment among children in Uganda. It is vital to screen all the children presenting to hospital for visual impairment. Majority of the causes of the visual impairment are preventable.Keywords: Visual impairment, Mulago National Referral Hospital, Eye clinic, Ugand

Population-Based Trachoma Mapping in Six Evaluation Units of Papua New Guinea.

PURPOSE: We sought to determine the prevalence of trachomatous inflammation - follicular (TF) in children aged 1-9 years, and trachomatous trichiasis (TT) in those aged ≥15 years, in suspected trachoma-endemic areas of Papua New Guinea (PNG). METHODS: We carried out six population-based prevalence surveys using the protocol developed as part of the Global Trachoma Mapping Project. RESULTS: A total of 19,013 individuals were sampled for inclusion, with 15,641 (82.3%) consenting to participate. Four evaluation units had prevalences of TF in children ≥10%, above which threshold the World Health Organization (WHO) recommends mass drug administration (MDA) of azithromycin for at least three years; Western Province (South Fly/Daru) 11.2% (95% confidence interval, CI, 6.9-17.0%), Southern Highlands (East) 12.2% (95% CI 9.6-15.0%), Southern Highlands (West) 11.7% (95% CI 8.5-15.3%), and West New Britain 11.4% (95% CI 8.7-13.9%). TF prevalence was 5.0-9.9% in Madang (9.4%, 95% CI 6.1-13.0%) and National Capital District (6.0%. 95% CI 3.2-9.1%) where consideration of a single round of MDA is warranted. Cases of TT were not found outside West New Britain, in which four cases were seen, generating an estimated population-level prevalence of TT in adults of 0.10% (95% CI 0.00-0.40%) for West New Britain, below the WHO elimination threshold of 0.2% of those aged ≥15 years. CONCLUSION: Trachoma is a public health issue in PNG. However, other than in West New Britain, there are few data to support the idea that trachoma is a cause of blindness in PNG. Further research is needed to understand the stimulus for the active trachoma phenotype in these populations
