ABSTRACT

Background:

Dengue is a major public health threat since 2005 in Pakistan. Because of their rapid expansion and long duration, dengue epidemics reduce the productive capacity and economic development of many sections of society. Evaluation is very important step of planning cycle to improve the utilization of resources.

Objective:

The overall objective of the study was to assess how quickly the system can detect epidemics and to measure the capacity of the system to monitor trends of its geographical distribution over time.

Methods:

A cross sectional study was conducted from July to September 2019 at Islamabad. Quantitative and qualitative assessment of system attributes was carried out according to Updated CDC Guidelines for evaluating public health Surveillance Systems, 2001.Stake holders were identified and approached. 4 different types of semi structured questionnaires were prepared for each level of stake holders.

Results:

Simplicity was very good, case definition was uniform and easily understandable. Flexibility is poor, the system is not capable of incorporating changes. Timeliness is excellent in terms of case reporting as well as case response by relevant stake holders. Data entry operators were less in number but expert in their work, however quality of data remained a challenge as 40 % forms were deficient in demographic and clinical information. Acceptability by the workers as well as population is very good. Sensitivity is high 87%. PVP is excellent 76%. Stability is good in terms of finances and logistics. Whereas representativeness is insufficient only 30%.

Conclusions:

The overall performance of the surveillance system for dengue in |Islamabad was excellent in terms of sensitivity and PVP. Timeliness is excellent and acceptability is very good. Whereas representativeness is poor. Coverage of the system needs to be extended and private set ups and laboratories to be included. Feedback being an important aspect of planning cycle needs improvement.
