Evaluating the effectiveness of Uganda's Supranational TB Reference Laboratory quality management system training program.

BACKGROUND: Achieving the targeted organizational goals through effective training can increase employee satisfaction. Since 2015, the Supranational Reference Laboratory Uganda (SRL Uganda) has trained National Tuberculosis Reference Laboratories (NTRLs) from 21 countries in a variety of areas that cover both technical and programmatic aspects pertinent to TB laboratories. The Laboratory Quality Management System (LQMS) under SRL coordinates actions intended to ensure sustained quality of the laboratory services offered by the National TB Reference Laboratories. In order for laboratory results to be helpful in a clinical or public health setting, they must be accurate, reliable, and timely. The LQMS course aims to provide learners with knowledge on how to attain and maintain this quality. Prior to this study, there was hardly any data available on the effectiveness of LQMS trainings provided by SRL Uganda; using Kirkpatrick model, which is popular among researchers for evaluating the efficacy of the training program, this paper seeks to establish the effectiveness of the LQMS training offered by the SRL Uganda. METHOD: We evaluated the effectiveness of LQMS training within the Uganda's SRL network for courses offered during the period 2017 and 2021 for participants from the Southern and East African sub-Saharan region. RESULTS: In 2017 and 2021, respectively, test results from 10/17 and 9/17 showed overall post-test scores above 80%. Of the 18 labs evaluated, 14 showed improvement; of these, 7 labs were from the Eastern region and the other 7 were from Southern Africa; one facility in this region also maintained its accreditation. In the post-evaluation assessment, attendees of the LQMS course gave feedback of strongly agree and agree variety. CONCLUSION: More SRL Uganda network laboratories in the regions achieved a 5-star SLIPTA level rating and among these, 5 NTRLs got ISO 15189:2012 accredited by the end of 2021, while one maintained its accreditation status. This proves that the Laboratory Quality Management System training program was an effective tool in improving the quality of laboratory services, work practices, and processes.

Human cytomegalovirus infection among febrile hematological cancer patients at the Uganda Cancer Institute.

Hematological cancers, including Leukemias and Lymphomas, and their associated chemotherapy and disease-specific factors, are linked to impaired granulocyte function and numbers, increasing the risk of opportunistic infections, often presenting as fever. Human cytomegalovirus (HCMV) is one of the significant opportunistic infections in these patients, but limited data exists on its seroprevalence and active infection burden among febrile hematological cancer patients in Uganda. We conducted a cross-sectional study from June to August 2017 at the Uganda Cancer Institute (UCI). Blood samples from 161 febrile hematological cancer patients were collected. HCMV exposure was assessed using indirect enzyme-linked immunosorbent assay for IgG and IgM antibodies, and active infection was confirmed with PCR testing and gel electrophoresis. IgG positivity indicated previous exposure, while positive IgM or PCR results indicated active infection. Overall, HCMV seroprevalence based on IgG and/or IgM positivity was 106/161 (66%). IgG alone, IgM alone, and combined IgG/IgM positivity prevalence rates were 57/161 (35.4%), 22/161 (13.6%), and 27/161 (16.7%), respectively. HCMV DNA PCR was positive in 5 of the 161 (3%) samples. Among PCR-positive patients, one (20%) was positive for IgG alone, two (40%) for IgM alone, and two (40%) for both IgG and IgM. Active infection based on positive IgM and HCMV DNA PCR was found in 23 of the 161 (14.3%) patients. Two-thirds of febrile patients with hematological malignancies in Uganda had been exposed to HCMV infection, with 14.3% showing active infection. Routine testing for active HCMV infection among febrile hematological cancer patients at the UCI is essential for timely and appropriate antiviral treatment. IMPORTANCE: In this paper, we demonstrated that over two-thirds of feverish patients with blood cancers such as leukemia at the Uganda Cancer Institute are already exposed to a type of virus infection called the human cytomegalovirus (HCMV), and 14% of the patients have active disease due to this virus. This was confirmed through finding blood samples testing positive for a type of protective antibody called IgM and also upon virus DNA detection in the blood of those patients. Routine testing for this virus is not usually done in the study settings. Our findings reveal and emphasize the importance of routinely testing blood samples for active infection with this virus among the feverish patients with blood cancers in the study settings, and prompt initiation of antiviral treatment of the actively infected patients.
