Development of mNavigator: Digital Health Application to Facilitate Compliance With Standardized Pediatric Cancer Treatment Protocols in Tanzania

PURPOSE Use of standardized treatment protocols has been demonstrated to improve outcomes for pediatric patients with cancer. Yet it is challenging to implement standardized treatment protocols in low- and middle-income countries as a result of infrastructure and resource constraints, as well as poor health provider compliance with treatment protocols. At Bugando Medical Centre (BMC) in Tanzania, health provider compliance with standardized paper-based treatment protocols is low at 22%. One-year overall survival rates among pediatric patients with cancer at BMC are 40% and almost one third of patients abandon treatment. We posit that improving protocol compliance in this setting may decrease treatment abandonment and improve survival rates. Use of digital case management systems has been shown to improve compliance with treatment protocols because of the ability to incorporate such features as decision-support algorithms, prompts and alerts, and checklists. The digital health application mNavigator was designed to facilitate health provider compliance with standardized pediatric cancer treatment protocols in Tanzania. METHODS mNavigator was developed by adapting an open-source digital case management platform called CommCare. The three stages of mNavigator development were as follows: workflow mapping and form development; form programming in CommCare; and quality assurance using mock and deidentified patient records to identify errors in information flow or outputs, assess preliminary usability, and determine areas for improvement. Standardized treatment protocols for Burkitt lymphoma and retinoblastoma were initially incorporated into mNavigator. The mNavigator prototype underwent usability testing at BMC before implementation in routine clinical practice. RESULTS Preliminary system usability, acceptance, and satisfaction evaluation demonstrated high usability response scores (> 80%). Perceived benefits of the mNavigator system included a user-friendly interface, improved record keeping, and assistance with patient tracking using standardized treatment protocols. Suggestions for improvement centered on the incorporation of other standardized treatment protocols (eg, Wilms tumor), improving interoperability with existing electronic recordkeeping systems, and making similar systems available for other clinical departments. CONCLUSION To our knowledge, mNavigator is the first digital health case management system specifically developed to improve health provider compliance with pediatric cancer treatment protocols in a low-resource setting. With high usability and acceptability, mNavigator has been implemented in routine clinical practice. Implementation and patient outcomes evaluations are ongoing and will inform the scale-up for use in other low- and middle-income countries.
