Data was collected through a format of questionnaire and was processed by hand sorting techniques, calculator and statistical program for social sciences (SPSS) version 16. The findings of the result showed that only 34 health facilities out of 72 are reporting and 38 not reporting. In 77% of health facilities had trained personnel in HMIS reporting, hence 62% reports received were found to be accurate. 62% reports were not submitted in time.
