Infectious diseases remain an important public health problem causing up to 63% of all childhood deaths and 48% of all premature deaths globally (1). Infectious diseases outbreaks if not detected and reported early, can rapidly spread and result in high morbidity and mortality (2). Effective public health surveillance systems can provide timely and accurate information leading to early detection of potential outbreaks and containing them in the local areas (3). Unfortunately, public health surveillance systems are poorly developed in many low and middle income countries (LMIC) as demonstrated by the recent Ebola outbreak in West Africa which led to devastating consequences in the health and economy of several countries (4,5).
A systematic approach is required to strengthen public health surveillance systems that can quickly detect and respond to the initial cases of disease outbreaks and other public health emergencies. The key strategy for implementing public health surveillance in the African countries is the Integrated Disease Surveillance and Response (IDSR) strategy which was launched by WHO Afro in 1998 (6). IDSR is used as one of the tools that help in the implementation of International Health Regulations (IHR) which are legally binding to member countries (7). IDSR also supports the implementation of the Global Health Security Agenda (GHSA) (8) and the One Health Initiative (OHI) (9, 10) which are used in many countries to strengthen countries’ capacity to prevent, detect, and rapidly respond to infectious diseases and other public health emergencies.
Although many countries have made significant progress in the implementation of IDSR, many challenges still hinder these countries from achieving optimal implementation. Though varied, many challenges are similar across the countries that have evaluated and published their IDSR performance. These challenges include: inadequate financial resources, poor coordination, weak laboratory capacity, poor communication systems, poor supervision, erratic feedback, inadequate training of health workers, lack of IDSR technical guidelines and reporting tools (11-16).
One of the main goals of IDSR implementation is to monitor disease and public health event trends in order to ensure that any unusual disease patterns such as outbreaks are detected quickly, investigated and responded to within the shortest time possible. For this reason, IDSR performance is often evaluated on completeness of reporting (proportion of health facilities and districts reporting) and timeliness of reporting (proportion of reports sent on time) (17, 18).
The IDSR system in Kenya has a total of 36 reportable priority diseases as per the 2nd Edition of IDSR Technical Guidelines adapted in 2012. The diseases are categorized as follows; diseases targeted for elimination, epidemic prone diseases, diseases of public health importance and public health events of internal concern under IHR 2005. These priority diseases have varying reporting timelines and requirements. The Kenyan surveillance system requires that some diseases are reported immediately within 24 hours, others weekly and others monthly.
Diseases/conditions that must be reported weekly are 23 as follows: Acute Flaccid Paralysis (AFP), Acute haemorrhagic fever syndrome (Ebola, Marburg, Lassa Fever, Crimean-Congo), Acute Jaundice, Adverse events following immunization (AEFI), Anthrax, Cholera, Dengue fever, Diarrhoea with blood (Shigella), Guinea Worm Disease (Dracunculiasis), Malaria, Malnutrition in under 5 years, Measles, Meningococcal Meningitis, Maternal death, Neonatal death, Neonatal tetanus, Plague, Rift Valley Fever, Severe Acute Respiratory Illness (SARI) clusters, Rabies, Typhoid, Yellow fever and Tuberculosis (Lab confirmed multidrug and extremely drug resistant Tuberculosis).
While many countries have migrated from paper-based to electronic IDSR reporting, not much is published about the electronic platforms that different countries are using for IDSR and the challenges that affect use of these platforms. The surveillance reporting system in Kenya remained mainly manual until 2007 when efforts were made to migrate to an Epi Info-based system (desktop system). Districts (now referred to as sub-counties) would compile their reports and send them to the national level via email, fax, courier or hand delivery. The national team would then enter the data into the digital desktop platform (Epi Info) for analysis. A weekly epidemiological bulletin was produced and shared back to the districts via email.
In 2011, the Ministry of Health (MOH) shifted reporting from the Epi Info system to a standalone (not integrated with other program systems) web-based system (also known as e-IDSR) due to challenges such as untimely and incomplete reporting especially from hard to reach areas. In this system, data from health facilities were captured electronically using computers at the sub-county level rather than at national level, while higher levels (national and county) were given rights to view and use the data. In August 2016, the country migrated eIDSR from the standalone system to the District Health Information System (DHIS2). The DHIS2 platform is an integrated web-based platform with capacity to report data from all other programs. System maintenance costs are therefore shared across programs making the system more sustainable.
Before the switch to DHIS2 in August 2016, all 47 county surveillance officers, 304 sub county surveillance officers, and 304 sub-county health records and information officers were trained on selected modules on IDSR surveillance strategy as well as the practical use of the DHIS2 platform. The training was conducted between January and June 2016 and also included facility surveillance focal persons from each of the Level 4 (sub-county), Level 5 (county) and Level 6 (national) health facilities.
After the switch to DHIS2, the surveillance focal persons based in health facilities continued to send surveillance reports (events-based or weekly disease workload) via a short message service (SMS) to the sub county surveillance officers who would then enter the data into DHIS2. The county surveillance officers (County Surveillance Coordinators and County Health Record and Information Officers) and national surveillance officers would then access and monitor the data by accessing the DHIS2. The flow of the surveillance data in Kenya is shown in Figure 1.
During the one month transition from eIDSR to DHIS2 in late 2016, completeness (proportion of health facilities submitting weekly reports) and timeliness of reporting plummeted from an average of 60% and 80% respectively to an average of 45% and 40%. respectively. The low reporting rates were attributed to inadequate training of surveillance officers on the new system. The MOH hypothesized that re-training surveillance officers would improve reporting rates and requested support to conduct a re-training of the county and sub county surveillance officers from counties where reporting rates were most affected (data entry is mainly done by sub county surveillance officers).Training was conducted between February and March 2017 by MOH with technical support from I-TECH Kenya. In this paper, we share the impact of training on timeliness and completeness of IDSR reporting rates in the new reporting platform. We also report on the challenges affecting the surveillance reporting rates at the various levels.
