International Public Health Laboratory Twinning: An Innovative Approach to Strengthen the National Health Laboratory System in Uganda, 2014-2017.

International initiatives to strengthen national health laboratory systems in resource-poor countries are often hampered by unfamiliarity with the country's health laboratory environment and turnover of international partners during the initiative. This study provides an overview of, and lessons learned from, the use of a laboratory long-term partnership approach (ie, "twinning") to strengthen the national public health laboratory system in an international setting. We focused on the partnering of the Uganda Ministry of Health Central Public Health Laboratory (CPHL) with the New Mexico State Public Health Laboratory to help the CPHL become Uganda's national public health reference laboratory (Uganda National Health Laboratory Services [UNHLS] Institute) and leader of its nascent Uganda National Health Laboratory Network (UNHLN). Via twinning, CPHL leadership received training on laboratory leadership and management, quality systems, facility management, and the One Health environmental strategy (ie, that the health of persons is connected to the health of animals and the environment), and drafted a National Health Laboratory Policy, UNHLS Institute business plan, and strategic and operating plans for the UNHLS Institute and UNHLN. The CPHL is now responsible for the UNHLS Institute and coordinates the UNHLN. Lessons learned include (1) twinning establishes stable long-term collaborations and (2) success requires commitment to a formal statement of activities and objectives, as well as clear and regular communication among partners.

A cholera outbreak caused by drinking contaminated river water, Bulambuli District, Eastern Uganda, March 2016.

BACKGROUND: A cholera outbreak started on 29 February in Bwikhonge Sub-county, Bulambuli District in Eastern Uganda. Local public health authorities implemented initial control measures. However, in late March, cases sharply increased in Bwikhonge Sub-county. We investigated the outbreak to determine its scope and mode of transmission, and to inform control measures. METHODS: We defined a suspected case as sudden onset of watery diarrhea from 1 March 2016 onwards in a resident of Bulambuli District. A confirmed case was a suspected case with positive stool culture for V. cholerae. We conducted descriptive epidemiologic analysis of the cases to inform the hypothesis on mode of transmission. To test the hypothesis, we conducted a case-control study involving 100 suspected case-patients and 100 asymptomatic controls, individually-matched by residence village and age. We collected seven water samples for laboratory testing. RESULTS: We identified 108 suspected cases (attack rate: 1.3%, 108/8404), including 7 confirmed cases. The case-control study revealed that 78% (78/100) of case-patients compared with 51% (51/100) of control-persons usually collected drinking water from the nearby Cheptui River (ORMH = 7.8, 95% CI = 2.7-22); conversely, 35% (35/100) of case-patients compared with 54% (54/100) of control-persons usually collected drinking water from borehole pumps (ORMH = 0.31, 95% CI = 0.13-0.65). The index case in Bwikhonge Sub-county had onset on 29 February but the outbreak had been on-going in the neighbouring sub-counties in the previous 3 months. V. cholera was isolated in 2 of the 7 river water samples collected from different locations. CONCLUSIONS: We concluded that this cholera outbreak was caused by drinking contaminated water from Cheptui River. We recommended boiling and/or treating drinking water, improved sanitation, distribution of chlorine tablets to the affected villages, and as a long-term solution, construction of more borehole pumps. After implementing preventive measures, the number of cases declined and completely stopped after 6th April.

Antimicrobial Drug Resistance in Blood Culture Isolates at a Tertiary Hospital, Uganda.

We summarize antimicrobial drug resistance (AMR) patterns from blood cultures at a tertiary hospital in Uganda. High rates of resistance to first-line antibiotic drugs were observed among Staphylococcus aureus and gram-negative organisms. Microbiology services with susceptibility testing should be strengthened to support standardized reporting of AMR data in sub-Saharan Africa.

Effectiveness of the credit-line approach for support of CD4 equipment functionality in northern Uganda

Background: Improving laboratory service delivery requires a functioning logistics and supply system. Uganda's Ministry of Health uses the credit-line approach to provide laboratory supplies including commodities for CD4 test equipment.Objectives: We examined the effectiveness of the credit-line approach in improving laboratory service delivery by using the functionality of CD4 test equipment as a proxy indicator. Method: A cross-sectional survey was conducted at 7 level-three health centres (HC IIIs); 18 level-four health centres (HC IVs); and 10 hospitals in 15 districts of mid-northern Uganda; including the Lango (17 facilities) and Acholi sub-regions (18 facilities); between July 2013 and August 2013. Functionality; was determined through self- and interviewer-administered questionnaires. The chi-squared test was used to assess differences in functionality by subregion; facility type; and equipment type.Results: A total of 38 CD4 test analysers were assessed. Of these; 26 (68%) were functional. In hospitals; 85% of CD4 analysers were functional; in HC IVs; 67% were functional and in HCIIIs; 43% were functional. The differences did not reach statistical significance. In the Langosub-region; 72% of analysers were functional; in the Acholi sub-region; 65% were functional. Non-functionality was mainly due to lack of reagents and cartridges; as well as low staffing levels of laboratory technicians with the skills necessary to operate the equipment.Conclusion: The credit-line approach supported the functionality of CD4 equipment in the surveyed facilities. However; there is a need to address issues of staffing and availability of reagents to enhance the functionality of CD4 equipment and improve patient care; especiallyat HC IIIs
