Strengthening routine data reporting in private hospitals in Lagos, Nigeria

The availability of routine health information is critical for effective health planning, especially in resource-limited countries. Nigeria adopted the web-based District Health Information System (DHIS) to harmonize the collection, analysis and storage of data for informed decision-making. However, only 44% of all private hospitals in Lagos State reported to the DHIS despite constituting 90% of all health facilities in the state. To bridge this gap, this study implemented targeted interventions. This paper describes (1) the implemented interventions, (2) the effects of the interventions on data reporting on DHIS during the intervention period and (3) the evaluation of data reporting on DHIS after the intervention period in select private hospitals in Lagos State. A five-pronged intervention was implemented in 55 private hospitals (intervention hospitals), which entailed stakeholder engagement, on-the-job training, in-facility mentoring and the provision of data tools and job aids, to improve data reporting on DHIS from 2014 to 2017. A controlled before-and-after study design was employed to assess the effectiveness of the implemented interventions. A comparable cohort of 55 non-intervention private hospitals was selected, and data were extracted from both groups. Data analysis was conducted using paired and independent t-tests to assess the effect and measure the difference between both groups of hospitals, respectively. An average increase of 65.28% (P < 0.01) in reporting rate and 50.31% (P < 0.01) in the timeliness of reporting on DHIS was seen among intervention hospitals. Similarly, the difference between intervention and non-intervention hospitals post-intervention was significantly different for both data reporting (mean difference = -22.38, P < 0.01) and timeliness (mean difference = -18.81, P < 0.01), respectively. Furthermore, a sustained improvement in data reporting and timeliness of reporting on DHIS was observed among intervention hospitals 24 months after interventions. Thus, implementing targeted interventions can strengthen routine data reporting for better performance and informed decision-making.
