Capacity building for laboratory strengthening and detecting antibiotic resistance: findings of a needs assessment in Uganda and Zambia Alliance for the Prudent Use of Antibiotics Antibiotic Resistance: Situation Analysis and Needs Assessment in Uganda and Zambia (AR-SANA) 1
2
AMR in Zambia: Key Findings S. pneumoniae resistance rates to penicillin rose from 14.3% resistance in 1990s to 53-67 % in 2007. Infants are most likely to have S. pneumoniae identified from their blood and spinal fluid. Co-trimoxazole resistance of S. pneumoniae is high (80-100%). Enteric infections that affected Zambian children were due to rotavirus and enteric bacteria (E. coli, V. cholerae, Salmonella spp., and Shigella spp.). Available data showed very high resistance among enteric bacteria to gentamicin, cefotaxime, nalidixic acid, ciprofloxacin, co-trimoxazole and cephalexin ranges between 70-100%.

Acute respiratory and enteric infections in Uganda are main causes of increased morbidity, mortality and costs. Streptococcus pneumoniae, and Haemophilus influenzae type b (Hib) continue to be the main bacteria responsible for Acute Respiratory Infections (ARI). Viral etiology (mainly Respiratory Syncytial Virus-RSV) in severe pneumonia among infants and children needs to be investigated. Empirical treatment should be guided by data provided by antibiotic resistance surveillance, particularly in common pathogens. Available information on Antibiotic Resistance (ABR) is in most cases scattered, incomplete and often unreliable. Alliance for the Prudent Use of Antibiotics AMR in Uganda: Key Findings

Purpose of the laboratory survey To examine: I. Laboratory capacity to conduct research on antibiotic resistance. II. Ability of laboratories to deliver accurate results III. Ability of laboratories to detect pathogens and perform antimicrobial sensitivity testing IV. Availability of a system for quality control in the laboratories V. Availability of mechanisms for dissemination of laboratory/ surveillance data VI. Availability of a system for collection, analysis and transmission of the data to be used for antibiotic management decisions VII. Economic situation of the survey laboratories VIII. Availability of the WHONET software for antimicrobial resistance surveillance 7
8
Method of laboratory survey 17 and 29 laboratories across Zambia and Uganda were surveyed respectively. Structured questionnaires (adapted from the WHO assessment form) were used to conduct the interview. Training of data collectors was carried out The survey was carried out 2009 and 2010. The study obtained ethical approvals from the University of Zambia Ethical Review Board, the Ethical Review Committee of Makerere University College of Health Sciences, Kampala, and Boston Tufts University Institutional Review Board 8

Uganda: Sources and supply of bacteriological laboratory consumables Alliance for the Prudent Use of Antibiotics14 68.9% - delays in obtaining reagents from the medical stores. 51.7% - Stock outs at the supply stores 34.5% -consumables are ordered but no deliveries received 6.9% -lack of information on how to make orders 3.4% - inconsistent demands for laboratory tests, lack of response on placed orders, delivery of what was not ordered and delivery of expired reagents
15
76.4% (13/17) of the laboratories admitted to experiencing problems in obtaining reagents from suppliers. 23% (4/17) of the laboratories experienced problems with reagent stock out at the medical stores. 58.8% (10/17), 41.2% (7/17) and, 11.8% (2/17) of the laboratories experienced delays in receiving ordered reagents from medical stores, inconsistency in the supply of laboratory consumables, and lack of knowledge on making orders, respectively.

Zambia: Quality assurance in isolation, characterization of microorganisms and antibiotic susceptibility testing 4/17 laboratories (23.5%) had external quality control procedures for antibiotic susceptibility testing, performed by: Acid-fast bacilli (AFB) microscopy National TB reference Laboratory National Institute for Communicable Diseases (NICD)/WHO, South Africa 18
19
Zambia: Availability and use of the WHONET software Only the University Teaching Hospital, Lusaka laboratory is currently using WHONET software (version 5.1 installed in May 2009) There is no national policy on antibiotic resistance surveillance 19

Functioning of equipment III. Equipment operation and maintenance standards IV. Equipment storage conditions, and the records of equipment calibration Bactec at the Lusaka University Teaching Hospital Microbiology Laboratory, 2009 21

Essential equipment is available in most laboratories, but often, the equipment is not maintained, calibrated, or in working condition 3. No standard specimen handling procedures 4. No sample disposal procedures 5. No antibiotic resistance surveillance systems in place in most hospitals 27
