SMS messages increase adherence to rapid diagnostic test results among malaria patients: results from a pilot study in Nigeria

Introduction:Hepatitis C virus (HCV) infection has emerged as one of the major global health challenge affecting about 2 - 3% of the world population. Epidemiological studies have shown that HCV infection is a major risk factor for development of Acute hepatitis,chronic liver disease,cirrhosis and Hepatocellular carcinoma (HCC).Early diagnosis of HCV is important to link hepatitis testing to care and treatment initiation. Aim:To compare sensitivity and specificity of rapid diagnostic test (RDT) with fourth generation ELISA Material and Method: This study was conducted in the Department of Microbiology at Atal Bihari Vajpayee Institute of Medical Sciences (formerly Post Graduate Institute of Medical Education and Research) and Dr Ram Manohar Lohia Hospital from January 2018 to December 2018.Blood samples of patients suspected with hepatitis were tested using ELISA and rapid diagnostic test Results: In our study 26378 blood samples were tested for HCV,using fourth generation ELISA.Of these,581(2.20%) samples were found to be positive by ELISA.These HCV positive samples along with equal number of ELISA negative samples were tested by rapid diagnostic test. Sensitivity and specificity of the rapid diagnostic test was found to be 72.98 % and 100% respectively. Discussion:Rapid diagnostic test can be used during emergency hours but their results must be followed by ELISA test results in a tertiary care hospital.Reporting of false negative results should be minimized for rapid linkage to treatment initiation and to avoid silent transmission of infection.

Abstract Background Ghana has adopted the policy of diagnostically testing for malaria before treatment. The Rapid Diagnostic Test (RDT) is used to diagnose malaria especially in lower health facilities like Health Centers (HC) and Community-based Health Planning Services (CHPS) Compounds without microscopy. Studies have shown that clinicians do not always adhere to negative malaria test results of the RDT and prescribe anti-malarials. Methods Quantitative aspect focused on how malaria is diagnosed and adherence to negative rapid diagnostic test results using the consulting room register and patients’ folder of six health facilities within the period of July to September 2015. In-depth interviews using purposive sampling was conducted for 14 health workers at Health Centers and CHPS compounds to find out their perceptions about malaria RDT and reasons for adherence or non-adherence to test results.Results Of the six health facilities in the Agona East District, 3.87% (14/362) were presumptively diagnosed with malaria whiles 96.10% (348/362) were diagnosed with malaria using RDT.For those tested with RDT, 15.25% tested negative and 84.75% tested positive. Of those who tested negative, 20.75% were given anti-malarials and 79.25% did not receive anti-malarials. Health workers perceived the Malaria RDT kit as easy to use and also as making work easier. Testing is done mainly because it is a policy. Conclusion The malaria testing rate in the Agona East District is higher than that at the National level. Health Centers compared to CHPS compounds are likely to treat for malaria in cases of a negative test result. There is also high adherence to negative test results. Health workers perceive the RDT as a useful tool which has made malaria diagnosis easy.

Abstract Background French Guiana (FG) is a French overseas territory where malaria is endemic. The current incidence rate is 0.74‰ inhabitants, and Plasmodium vivax is widely predominating even though Plasmodium falciparum is still present due to imported cases mainly from Africa. In FG, rapid diagnostic test (SD Malaria Ag P.f/Pan®) is based on the detection of pan-pLDH, PfHRP2, and PfHRP3 antigens, while in South America, the share of deletion of PfHRP2 gene is significantly increasing. Accordingly, the study questions the reliability of RDTs in the Amazonian context. Methods The study is retrospective. It is conducted over 4 years and analysed 12,880 rapid diagnostic tests (RDTs) compared to concomitant Blood Film Tests (BFTs) sampled for malaria diagnosis. Results The global assessment of the accuracy of SD Malaria Ag P.f/Pan® in the diagnostic of malaria shows both Positive and Negative Predictive Values (PPV and NPV) higher than 95%, except for PPV in the diagnosis of malaria to P. falciparum (88%). Overall, the concordance rate between RDT and BFT (positive/positive; negative/negative) was 99.5%. The PPV of the RDT in the follow-up of patients diagnosed with P. falciparum was the lowest during the first 28 days. The PPV of the RDT in the follow-up of patients diagnosed with P. vivax was the lowest during the first 21 days. The global sensitivity of SD Malaria Ag P.f/Pan® test was, on average, 96% (88.2–100) for P. falciparum and 93% (90.6–94.2) for P. vivax. The global specificity was 99.8% (99.5–100) for all included species. Conclusion SD Malaria Ag P.f/Pan® is a reliable rapid test used for the first-line diagnosis in remote healthcare centres. The test results should be interpreted in the light of patient’s recent medical history and the date of arrival to FG.

Abstract Purpose Even with rapid diagnostic technology to swiftly identify infectious organisms, prompt response is needed to translate results into appropriate actions. The purpose of this study was to determine if the introduction of real-time pharmacist response to positive rapid diagnostic test results would decrease time to antimicrobial therapy for gram-positive bacteremia and candidemia in a community hospital setting. Methods A quasi-experimental study was conducted in 2 community hospitals. The study comprised 2 cohorts of adult patients who tested positive for gram-positive bacteremia involving Staphylococcus aureus, Enterococcus faecalis, Enterococcus faecium, or Candida species. The preintervention cohort consisted of patients admitted from November 2017 through May 2018. The intervention cohort consisted of patients admitted from July 2018 through January 2019, after the intervention went live. The primary outcomes were time to optimal antimicrobial therapy and time to effective antimicrobial therapy. Results A total of 140 patients were included in the preintervention group, with 124 patients included in the intervention group. The mean (SD) time to effective therapy decreased from 13.9 (21.6) hours in the preintervention group to 8.6 (12.5) hours in the intervention group (hazard ratio [HR], 1.15; 95% confidence interval [CI], 0.89-1.48; P = 0.29). The mean (SD) time to optimal therapy significantly decreased from 53.7 (57.7) hours in the preintervention group to 38.4 (31.5) hours in the intervention group (HR, 1.73; 95% CI, 1.33-2.26; P < 0.001). Conclusion The introduction of real-time pharmacist response to positive rapid diagnostic test results led to a significant decrease in time to optimal antimicrobial therapy but did not significantly affect time to effective therapy. The results showed that the allocation of limited resources of a community hospital to such a stewardship program is justifiable.

Abstract Background: China has made significant progress towards malaria elimination by achieving zero reports of indigenous malaria cases over two consecutive years. The diagnosis of malaria, which is based on microscopic examination, still remains a challenge, due to a lack of sensitivity for detecting low-level parasitaemia. This study aimed to evaluate the diagnostic value of a novel immunochromatographic test strip for imported malaria. Methods: After obtaining informed consent, blood samples were collected from migrants returning home from Africa to Shanglin County in Guangxi, PR China, in 2018-2019, and were tested with the novel test strips. The test results were compared with those of microscopic examination, commercial malaria rapid diagnostic test (RDT), and polymerase chain reaction (PCR) assay. Results: A total of 535 samples were tested. Both microscopy and PCR test results showed a total of 162 (30.28%) malaria-positive samples, of which 99 were positive for Plasmodium falciparum (P. falciparum), three for P. vivax, five for P. malariae, and 50 for P. ovale, whereas five had mixed infections. The sensitivity, specificity, and efficiency of the novel RDT were 74.1%, 93.0%, and 87.3%, respectively, whereas its sensitivity of detecting P. falciparum, P. vivax, P. malariae, and P. ovale was 91.9%, 100%, 20.0%, and 44.0%, respectively. Furthermore, the sensitivity, specificity, and efficiency of the commercial RDT were 86.0%, 89.3%, and 88.2%, respectively, whereas its sensitivity of detecting P. falciparum, P. vivax, P. malariae, and P. ovale was 96.0%, 100%, 40.0%, and 70.0% respectively. The differential detection of Plasmodium species using the new RDT was significantly better compared to that of the commercial RDT (c2 = 14.73; P = 0.0001), which can detect only P. falciparum. This was consistent with Kappa analysis (Kappa = 0.881). A significant difference (c2 = 24.50; P < 0.0001) in the detection rate of other Plasmodium species was observed with an average consistency using Kappa analysis (Kappa = 0.716). Conclusion: The novel malaria RDT test strip had high sensitivity and specificity in detecting P. falciparum and P. vivax. Improvement in P. ovale and P. malariae detection efficiency may lead to the scale-up of this RDT in the future.
