Evaluation of the Babies At Risk Surveillance System in Rushinga District, Mashonaland Central Province, Zimbabwe, 2015

Background: About 15% of world’s population lives with some disability. Zimbabwe’s prevalence of disability was at 7% in 2013. ARSS is a paper-based system to monitor and detect neuro-developmental conditions and childhood disability early. Indicators for registering a baby into ARSS include: low Apgar score, low birth weight and birth asphyxia. Active case finding in Rushinga District in July 2015 identified nine cerebral palsy cases that were missed by the system out of 14 randomly chosen babies delivered at Chimhanda District Hospital. We evaluated the performance of the ARSS in Rushinga District. Methods: We evaluated the system using CDC guidelines for surveillance systems evaluation. All 12 health facilities in Rushinga were included. Health workers involved in ARSS were purposively recruited. Interviewer administered questionnaire, key informant interview guide, checklists and records review were used for data collection. Knowledge of participants on the system was assessed using five-point Likert scale. Data were analyzed using Epi Info 7. Results: Fifty-one participants were recruited for the study. Median years in service for all participants was 7 (Q1 = 6;Q3 = 12). Average knowledge score was 3. Majority participants (82.4%) were not trained on ARSS and cited lack of: knowledge, reporting guidelines, induction and focal persons as reasons for missing AR cases. Currently, ARSS is able to detect only 12.5% of cases. Prevalence of AR babies in Rushinga for period November 2014 to November 2015 was 21.1%. Monthly cost of detecting and registering a case was USD$52.46. Conclusions: ARSS was found to be useful, simple, acceptable and affordable, however was found to be unstable and not sensitive. Training of health workers particularly village health workers and integrating ARSS with the DHIS2 could improve system performance. As a result of the evidence from this evaluation, it has been agreed to include ARSS data on the monthly return form (T5) beginning June 2016.

Reinfection of urogenital schistosomiasis in pre-school children in a highly endemic district in Northern Zimbabwe:a 12 months compliance study

Background:In light of the shift to aiming for schistosomiasis elimination,the following are needed:data on reinfection patterns,participation,and sample submission adherence of all high-risk age groups to intervention strategies.This study was conducted to assess prevalence,reinfections along with consecutive participation,sample submission adherence,and effect of treatment on schistosomiasis prevalence in children aged five years and below in an endemic district in Zimbabwe,over one year.Methods:The study was conducted from February 2016-February 2017 in Madziwa area,Shamva district.Following community mobilisation,mothers brought their children aged 5 years and below for recruitment at baseline and also urine sample collection at baseline,3,6,9 and 12 months follow up surveys.At each time point,urine was tested for urogenital schistosomiasis by urine filtration and children found positive received treatment.Schistosoma haematobium prevalence,reinfections as well as children participation,and urine sample submission at each visit were assessed at each time point for one year.Results:Of the 535 children recruited from the five communities,169(31.6%)participated consecutively at all survey points.The highest mean number of samples submitted was 2.9 among communities and survey points.S.haematobium prevalence significantly reduced from 13.3%at baseline to 2.8%at 12 months for all participants and from 24.9%at baseline to 1.8%at 12 months(P<0.001)for participants coming at all-time points.Among the communities,the highest baseline prevalence was found in Chihuri for both the participants coming consecutively(38.5%,10/26)and all participants(20.4%,21/103).Reinfections were significantly high at 9 months follow up survey(P=0.021)and in Mupfure(P=0.003).New infections significantly decreased over time(P<0.001).Logistic regression analysis showed that the risk of acquiring schistosomiasis was high in some communities(P<0.05).Conclusions:S.haematobium infections and reinfections are seasonal and depend on micro-geographical settings.The risk of being infected with schistosomes in pre-school aged children increases with increasing age.Sustained treatment of infected individuals in a community reduces prevalence overtime.Participation compliance at consecutive visits and sample submission adherence are important for effective operational control interventions.
