Abstract

BackgroundIntegrated Disease Surveillance and Response (IDSR) is a cost-effective surveillance system designed to curb the inefficiency associated with vertical (disease-specific) programs. The study determined the existence and effect of vertical programs on disease surveillance and response in Nigeria.MethodsA cross-sectional study involving 14 State epidemiologists and Disease Notification Surveillance Officers (DSNOs) in 12 states located within the 6 geopolitical zones in Nigeria. Data was collected using mailed electronic semi-structured self-administered questionnaires. Response rate was 33.3%. The data was analyzed using SPSS version 20.ResultsHalf of the respondents were males (50.0%) and State epidemiologists (50.0%). Malaria, HIV/AIDS, tuberculosis, and other diseases were ongoing vertical programs in the States surveyed. In over 90% of cases, vertical programs had different personnel, communication channels and supportive supervision processes different from the IDSR system. Although less than 50% acknowledged the existence of a forum for data harmonization, this forum was ineffectively utilized in 83.3% of cases. Specific disease funding was higher than that of IDSR (92.9%) and only 42.9% reported funding for IDSR activities from development partners in the State. Poor data management, low priority on IDSR priority diseases, and donor-driven programming were major negative effects of vertical programs. Improved funding, political ownership, and integration were major recommendations preferred by the respondents.ConclusionWe found that vertical programs in the surveyed States in the Nigerian health system led to duplication of efforts, inequitable funding, and inefficiencies in surveillance. We recommend integration of existing vertical programs into the IDSR system, increased resource allocation, and political support to improve IDSR.

Highlights

Programs with specific objectives, focused on specific health programs are in particular attractive to donors because of the need to have measurable investment results [1]
Most of them stated that vertical programs have different data forms from Integrated Disease Surveillance and Response (IDSR) (78.6%) and that these data did not correspond with that from IDSR (92.9%)
The existence of a forum for data harmonization between IDSR and vertical programs was reported by 42.9% of the respondents with 83.3% of those who reported the existence of the form stating that it was not effectively utilized (Table 2)

Summary

Introduction

Programs with specific objectives, focused on specific health programs are in particular attractive to donors because of the need to have measurable investment results [1] This describes the nature of vertical programs which usually have quantitative, specific, and defined objectives and typically target a single condition or small group of health problems. Some other advantages of vertical programs include financial control, the ability to respond to changing circumstances, and the identification of new strategies. The fact that these programs have objectives that are achievable in a limited time frame and are preferred by external donors makes them beneficial [1].
