Antibiotic Resistance: Situation Analysis and Needs Assessment in Uganda and Zambia (AR-SANA) 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
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%.

Antibiotic resistance by drug and selected pathogens in Zambia
Mortality from severe S. pneumoniae pneumonia of children in the University Teaching Hospital, Zambia, 2005-2007
AMR in Uganda: Key Findings • 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.

Antibiotic resistance profiles of S. pneumoniae from 2005- 2007 in Kampala Data from Mulago Hospital Laboratory Data Alliance for the Prudent Use of Antibiotics
Purpose of the laboratory survey To examine: • Laboratory capacity to conduct research on antibiotic resistance. • Ability of laboratories to deliver accurate results • Ability of laboratories to detect pathogens and perform antimicrobial sensitivity testing • Availability of a system for quality control in the laboratories • Availability of mechanisms for dissemination of laboratory/ surveillance data • Availability of a system for collection, analysis and transmission of the data to be used for antibiotic management decisions • Economic situation of the survey laboratories • Availability of the WHONET software for antimicrobial resistance surveillance
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

Source Number of laboratories Medical Stores limited 7 National Medical Store 7 Commercial Suppliers 3 Zambia: Sources and supply of bacteriological laboratory consumables 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.
Scores of Zambian Laboratories Alliance for the Prudent Use of Antibiotics
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
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
Uganda: Quality assurance in isolation, characterization of microorganisms and antibiotic susceptibility testing • Only 6.6% have external quality control procedures for Antibiotic Susceptibility, performed by: • Center for Public Health Laboratories (CPHL) • None (0/29) of the surveyed laboratories installed or used the WHONET software to monitor AMR. Availability and use of the WHONET software Alliance for the Prudent Use of Antibiotics
Availability of Laboratory Equipment The survey of laboratory equipment examined the following: Availability of the essential equipment required to provide routine clinical diagnostics Functioning of equipment Equipment operation and maintenance standards Equipment storage conditions, and the records of equipment calibration Bactec at the Lusaka University Teaching Hospital Microbiology Laboratory, 2009
Availability of Laboratory Equipment Most of the surveyed laboratories had the essential equipment needed to perform clinical diagnostics Some of this equipment was not in working condition. Most of the laboratory equipment was not regularly calibrated and maintained.

Charges of tests (US$) performed by Zambian laboratories 11/17 laboratories charged user fees for clinical tests Average costs for performing blood smear for malaria, urinalysis, sputum, blood , CSF , and stool cultures by different laboratories
Charges of tests (US$) performed by Ugandan laboratories 55.2 % (16/29) of the laboratories surveyed charged fees for each laboratory test. The highest cost was of CSF and blood cultures Average costs for performing blood smear for malaria, urinalysis, Sputum, blood culture, CSF cultures, and stool cultures by different laboratories Alliance for the Prudent Use of Antibiotics
Specimen handling Some laboratories discarded specimens a few days after testing. Most of the laboratories had no criteria for sample disposal. Alliance for the Prudent Use of Antibiotics
Conclusions and Major Constraints • Limited antibiotics susceptibility testing capabilities. • Essential equipment is available in most laboratories, but often, the equipment is not maintained, calibrated, or in working condition • No standard specimen handling procedures • No sample disposal procedures • No antibiotic resistance surveillance systems in place in most hospitals
Conclusion and major constrains (continued) • Lack of adequate funding for laboratory equipment, reagents, staff, stationery, and consumables • No standard procedures on antibiotic susceptibility testing • Problems with reagent stock-outs from suppliers and medical stores • Delays in receiving laboratory supplies • Inconsistent reporting of notable diseases to national and district health authorities
