CommentaryBackground: Globally, there has been an increase in the demand for quality data for evidence-based planning. One of the sources of data is the Routine Health Information Systems (RHIS), which collect the information regularly on agreed upon schedule and by using standardized tools [1]. Despite being criticized for its inaccuracy, the RHIS data has the potential of gathering the much-needed data to inform the planning of health intervention beyond providing data on services utilization [1][2][3][4][5]. Institutions have pioneered the tools and frameworks for assessing the data quality and improving the performance of the RHIS [1,6,7]. However, most of these tools examine overall systems performance rather than the source documents such as registers [1].The Tanzania RHIS context: Tanzania is using the paper-based registers to collect process and analyse, and transmit patient's routine health information data, from the health facilities up to the district. The RHIS comprises of over ten sets of registers and 70 processing and reporting forms [8,9]. Each clinician/nurse records client consultation into the registers and simultaneously counts each diagnosis using the tally sheets. At the end every month the data is summarized into the secondary data forms for reporting purposes to the health management team at the district, the region and the ministry of health. At the district level, the DHIS2 focal person uploads the monthly reports into opensource software.We embarked in the assessment of the quality of data collected using individual health records contained in the health facility's paper-based registers by examining four determinant of data quality [5] The determinants included completeness of data elements, the timeliness of report submission, and the accuracy of the collected data [1,5,7,10]. This commentary re-examines some of the methodological challenges of conducting the assessment of data quality and lessons learned during the design and the execution of the study in the poor resource settings.
MethodsThe study design was a retrospective case series, analysing children aged below five years, also referred to as under five outpatient registers. The authors included in this study all registers completed from October 2013 March 2014 from 24% (10/42) of the health facilities of Ilemela municipality, Mwanza region. The authors developed the study design under the assumptions that the registers may have missing individual records, the health workers may not submit the monthly reports on time and that there might be a discrepancy between the actual registers counts of diseases of interest and the monthly reports submitted to the health management team. The detailed methods, which forms basis for this commentary is available from Kabakama, 2016 [5].
Results and DiscussionThe main challenges of the study methods used is that it is timeconsuming and costly mainly due to transcribing and decoding of the patient's records into the meaningful electronic software for easy analysis, and interpretation of the q...
