Background: Integrated Diseases Surveillance and Response (IDSR) strategy was adopted in most countries in Africa since 1998. The Gambia adopted its first IDSR Technical Guidelines in 2003 but has never had it evaluated. The aim of this study is to determine whether Gambia Armed Forces (GAF) IDSR is meeting its objective and to evaluate the attributes of the system. Methods: A cross-sectional study was conducted among health care workers in GAF on IDSR surveillance system using a structured questionnaire. The updated CDC guidelines on surveillance system evaluation were used to access the attributes of the GAF – IDSR using the kobocollect and excel version 2010 were used to analyze. Five attributes; usefulness, acceptability, simplicity, data quality & completeness were used to achieve objectives. Attribute were summed up scores for all questions for each attribute and divided by the number of questions and multiplied by 100. Each attribute is described as good/simple/timely/complete/has quality/has good acceptability with scores >50% and vice versa if scores are <50%. Results: The study reveals that 52.9% (9/17) of participants are between aged 21-30 years, 35.3% (6/17). 64.7% (11/17) of the study participants spent between 10-15 years in services. 64.7% (11/17) conduct only out-patient. On the level of training, 52.9% (9/17) of the participants are trained nurses. From the study usefulness score was 25.0%, simplicity was 19.2%, acceptability was 17.6%, stability was 14.9%, Data quality was 12.4%, and timeliness and completeness each were 11.8%. None of the attribute scores met the cutoff point. Conclusions: The IDSR surveillance system in GAF in The Gambia was not useful, not simple, not timely in submitting complete report not flexible and unstable. Training was a gap that was identified during the study as only three among the study participant and in the whole institution is trained on IDSR and disease surveillance.
