Performance assessment of laboratory technicians on Malaria Microscopy in 5 high endemic districts of Rwanda

Parasitological diagnosis plays an increasing role in malaria control and elimination. Noella Umulisa, Angelique Mugirente, Tharcisse Munyaneza, Aniceth Rucogoza, Aline Uwimana, Beata Mukarugwiro, Stephen Mutwiwa, Aimable and Mbituyumuremyi of the
Maternal and Child Survival Program, Jhpiego, the National Reference Laboratory, Rwanda Biomedical Centre (RBC), and the Malaria and Other Parasitic Diseases Division (Mal & OPDD) in Rwanda will present their experiences building the capacity of lab technicians during Session 47 at the American Society of Tropical Medicine and Hygiene Annual Meeting on 6 November 2017.  Their abstract is found below.

Accurate malaria diagnostics help to establish the true prevalence of each Plasmodium species and can ensure appropriate treatment. Light microscopy is the gold standard for malaria diagnosis and sufficient training of laboratory staff is paramount for the correct microscopy diagnosis of malaria. In Rwanda each of about 400 health centers has a laboratory able to perform malaria microscopy, at least 2 trained lab technicians and 1 to 2 functioning microscopes.

The objective of the study is to evaluate the performance of laboratory technicians in detecting and quantifying malaria parasites in 81 health centers from 5 highly endemic districts (Huye, Nyanza, Ngoma, Kirehe, Kayonza, Gatsibo). In October 2015 the Rwanda Biomedical Center and partners trained 1 lab technician per health center from these districts in malaria microscopy.

The training emphasized determining parasite density and detection of malaria species. From August to September 2016 a follow-up assessment was conducted. Of the 81 technicians trained, 30 were randomly chosen and assessed at their health facilities.

A standardized pre-validated slide panel of 5 slides was distributed, a comprehensive checklist used to collect information and conduct visual inspection and maneuvers used in routine malaria diagnosis. During the training a significant increase was found between pre and post tests with median scores improving from 47% to 85%.

As part of the assessment 150 lab tech-prepared slides were analyzed to evaluate the quality of thick and thin blood smears. There was a significant increase in quality of both blood smear types. The sensitivity and specificity of participants in detection of malaria parasites were 100% and 86% respectively, while species identification and parasite quantification accuracy were 79% and 75% respectively.

The findings of this assessment support the need for continuous capacity building for laboratory staff to ensure accurate malaria diagnosis for appropriate treatment and suggest that District hospitals may benefit from conducting regular malaria microscopy diagnosis quality control/assurance activities at health center laboratories.

World Health Workers Week, a Time to Recognize Health Worker Contributions to Malaria Care

Since the beginning of the Roll Back malaria Partnership in 1998 there has been strong awareness that malaria control success is inextricably tied to the quality of health systems. Achieving coverage of malaria interventions involves all aspects of the health system but most particularly the human resources who plan, deliver and assess these services. World Health Worker Week is a good opportunity to recognize health worker contributions to ridding the world of malaria.

We can start with community health workers who may be informal but trained volunteers or front line formal health staff.  According to the Frontline Health Workers Coalition, “Frontline health workers provide immunizations and treat common infections. They are on the frontlines of battling deadly diseases like Ebola and HIV/AIDS, and many families rely on them as trusted sources of information for preventing, treating and managing a variety of leading killers including diarrhea, pneumonia, malaria and tuberculosis.”

The presence of CHWs exemplifies the ideal of a partnership between communities and the health system. With appropriate training and supervision CHWs ensure that malaria cases are diagnosed and treated promptly and appropriately, malaria prevention activities like long lasting insecticide-treated nets are implemented and pregnant women are protected from the dangers of the disease. CHWs save lives according to Nkonki and colleagues who “found evidence of cost-effectiveness of community health worker (CHW) interventions in reducing malaria and asthma, decreasing mortality of neonates and children, improving maternal health, increasing exclusive breastfeeding and improving malnutrition, and positively impacting physical health and psychomotor development amongst children.”

CHWs do not act in isolation but depend on health workers at the facility and district levels for training, supervision and maintenance of supplies and inventories. These health staff benefit from capacity building – when they are capable of performing malaria tasks, they can better help others learn and practice.

A good example of this capacity building is the Improving Malaria Care (IMC) project in Burkina Faso, implemented by Jhpiego and supported by USAID and the US President’s malaria Initiative. IMC builds capacity of health workers at facility and district level to improve malaria prevention service delivery and enhance accuracy in malaria diagnosis and treatment. Additionally capacity building is provided to health staff in the National Malaria Control Program to plan, design, manage and coordinate a comprehensive malaria control program. As a result of capacity building there has been a large increase in malaria cases diagnosed using parasitological techniques and in the number of women getting more doses of intermittent preventive treatment to prevent malaria during pregnancy.

Malaria care is much more than drugs, tests and nets. Health worker capacity is required to get the job done and move us forward on the pathway to eliminate malaria.
