EQA in the SADC Region E N Sibanda
Assessment of NRL • NRL in MS were assessed at the behest of the SADC • The purpose was to assess existing capacity and recommend ways of improving service delivery • The major services targeted were HIV and AIDS, Tuberculosis and Malaria
Context • The strengthening of labs is integral component of the • The Millennium Development Goals, • the Abuja Process • the Maputo Declaration • the SADC whose Protocol on Health has outlined strategies and activities for the control of these three diseases. • The latter are premised on the principle that a coordinated regional effort is necessary to compliment national strategies.
Assessment • Visits to MS • Perusal of relevant, availed documentation • Interviews with stakeholders • Observation of the lab. operations
Major Findings • Laboratory policy inconsistent • Human resources inadequate • Organizational structures variable • Vertical programs and horizontal programs • Quality Management poorly understood, poorly implemented and impacting negatively on service delivery
Assessment of QA • SOPs availability, updating • Staff training in QA • Availability of designated QA officer • QA for services provided • Quality Manuals • Participation in EQA • EQA schemes used • Implementation and documentation of corrective measures
QA assessment Score Card • Areas of assessment Target score • QA Management policy 3 • Presence of Quality Officer 2 • Participation in EQA scheme (national or any other) 1 • SOPS available 1 • SOPs updated, signed 1 • Routine IQC with charts displayed 1 • Documentation of corrective action 1 • Total achievable points 10
Specific areas: HIV and AIDS • random sampling and retesting of 10% of all the tests carried out at the VCT site • Retesting with rapid tests or ELISA. • In Namibia 100% samples retested using ELISA • WHO no longer recommends 10% retesting • ELISA assays infrequently performed • documentation confirming participation in QA for ELISA schemes was not always available. • number of countries have started piloting the national EQAs using dried tube specimens
Lymphocyte subsets (CD4) • Most successful EQA program in SADC • WHO supported • Different EQA schemes used • Tanzania & Zambia EQA for CD4 testing is provided by a Canadian scheme. • Namibia EQA is provided by QASI and Thistle in South Africa. • Malawi EQA is provided by UNC, AFREQUAS, REQUAS, and UK-NEQUAS NEQAS • Swaziland EQA is provided by the WHO/NICD scheme. • South Africa and Zimbabwe have national quality assurance schemes.
CD4 EQA • Good uptake • Almost all NRL were participating • Not always understood by people in the labs • Perceived to be a n imposed WHO requirement • Poor implementation of corrective measures • fundamental misunderstanding of the role and usefulness of EQA
TB • Variable practices (best in Lesotho and Madagascar) • SOPs are available and regularly updated • Routine use of approved IQC samples for all cultures. • Central lab supports district laboratories with QC • The mode of QA is on-site testing • designated QA officer from the Central laboratory in Maseru visits the district hospital laboratories • blind re-examination of random samples of smears in the presence the resident microscopist or technician. • Released results are compared with on-site findings • corrective measures necessary implemented in loco
TB • EQA for the Central TB laboratory is through schemes in South Africa. • QC for TB microscopy is provided by the NICD at the NHLS in Johannesburg, South Africa. • Six monthly batches of samples are received for routine microscopy. • The partners in South Africa are overwhelmed by referral work and the turnaround is slow and does not adequately address the needs of the Laboratory in Maseru. • TB culture EQA • is provided by the MRC in South Africa. • 20 samples are provided for culture, identification and detection of organisms. • Problems include the unavailability and appropriateness of basic sample packaging materials that fulfil relevant IATA requirements.
TB Culture • predominantly provided by the MRC in Pretoria. • Zambia, Swaziland, Lesotho, Namibia, Botswana are amongst the countries receiving 6 monthly cycles of culture EQA with the MRC laboratory. • Twenty samples are sent by the MRC scheme for processing and reporting by the national laboratory. • The turn-around of reports was reported as satisfactory in Malawi, Zambia and Namibia. • The NHLS group of laboratories Referral laboratory provides microscopy EQA.
Malaria • The two aspects of QA • QA of the test • QA of the health worker performing the test. • Blind retesting of 10% of slides examined • Madagascar upwardly cascading QA program for malaria. • blind retesting of slides reported as positive or negative by the District tech same proportion sent to a regional and National level facility. • DRC intra-laboratory test accuracy and inter-laboratory QC is co-ordinated by the malaria National Reference laboratory in the INRB. • QC program is affiliated to WHO/NICD EQC & habitually scores 100%. • None of the MS had External Quality assurance for malaria.
Overall recommendations • Four documents produced and accepted by Ministers of health of all SADC MS • Functions and Minimum standards of NRL • Functions and min standards of SNRL • Operationalisation of Regional Centres of Excellence
RCE for Quality Management • Areas of assessment Score • The existence of accredited quality assurance schemes. 4 • Adequate numbers of technically competent personnel 3 • Expertise in development of training modules in QM 2 • Adequate capacity to roll out QA and PT services to MS NRLs 1 • Conducive administrative environment 1 • Logistics necessary to handle potentially infectious materials 1 • Adequate infrastructure to provide training. 1 • Communications (Telephone, E-mail, Internet) 1 • Accessibility 1 • Total 15
Operationalisation • !. Adoption of recommendations by SADC • Call for MS to express an interest in RCE • Dispatch of team of uninterested experts to assess capacity • Generation of a shortlist • Selection of site by Ministers of Health
What are ZINQAP chances? • Very high • One of two accredited EQA schemes in the region • Well staffed, structured, operational • Meet almost all the criteria for assessment • SA schemes overwhelmed
