Surveillance Evaluation of Amoebic Dysentery in Padangbasar Hospital, Sadao District, Songkhla Province, Thailand, 2013

Abstract

Dysentery is an infection of small and large bowels. There are two major causative pathogens which is Shigella spp. (invasive bacteria) and Amoeba histolytica (protozoa). The notifiable disease report of amoebic dysentery at Padangbezar hospital was increasing during 2009 – 2013. But the reporting number of notifiable disease surveillance and diagnosis program (Hosxp) was markedly different. Furthermore, two cases of amoebic dysentery were health care workers of Padangbezar hospital. Thus the hospital surveillance team conducted the surveillance evaluation of amoebic dysentery during 1 January – 31 December 2013. The objectives were aimed to describe the surveillance system, to study the qualitative and quantitative attributes and to provide the recommendation to improve the amoebic dysentery surveillance. Total 493 medical records were recruited from the ICD-10 but only 67 records met the case definition of amoebic dysentery. Of these 67 cases, only 52 cases were reported to the system. The sensitivity and predictive positive value was 76.12% and 98.92% respectively. The representative was good and timeliness was 100%. The accuracy of data was 92.43%. The acceptability, usefulness, flexibility and stability were good. But there should improve the acceptability by allow other personnel to report amoebic dysentery when the laboratory was positive. In case of the attending clinician was not yet diagnosed. And the stability was strengthening by providing the summary of surveillance report to all staffs routinely.
