Background: Cancer is a growing public health concern in Tanzania (and throughout sub-Saharan Africa), with a majority of cases presenting in late stage with associated distress, ie, pain. Access to specialty palliative care (PC) is a national priority in Tanzania; however, there are limited numbers of PC specialists (hereafter, specialists). Mobile health promises to extend the reach of a limited pool of specialists through inter-professional, community-based care coordination. This work assessed the effectiveness of a smartphone-/web-based application, mobile Palliative Care Link (mPCL), to extend specialist access via shared data and communication with local health workers (LHWs). Central to mPCL is the African Palliative care Outcome Scale (POS), adapted for automated, scheduled mobile symptom assessment and response. Methods: Following consent, incurable adult cancer patients were randomized at hospital discharge from a large urban, government-supported Tanzanian cancer institute to one of two study arms—mPCL or phone-contact POS collection. Baseline sociodemographic, clinical and POS data were recorded. Twice-weekly POS responses were collected and managed via mPCL or by phone-contact with clinician study personnel for up to 4-months depending on respective study arm. Patient end-of-study care satisfaction was assessed via phone-survey. Results: Forty-nine patients per arm participated. Comparison of baseline characteristics showed a trend toward more women ( p= 0.07) and higher discharge morphine use ( p= 0.09) in the mPCL versus phone-contact groups, respectively, and significant between-group differences in cancer types ( p= 0.003). Proportion of deaths were near-equal comparing groups [26% ( n= 13) mPCL versus 28% ( n= 14) phone-contact]. Overall symptom severity was lower in the phone-contact group ( p <0.0001) and symptom severity decreased over time in both groups ( p= 0.0001); however, between-group change in overall symptoms over time did not vary ( p= 0.34). Care satisfaction was high overall in both groups with few between-groups differences, ie, greater provider response to questions and concerns in the phone-contact arm and greater provision of spiritual support in the mPCL arm. Conclusions: Higher symptom severity scores in the mPCL arm likely reflecting between-group sociodemographic/clinical differences and clinical support of phone-contact arm participants. Similar rates of care satisfaction in both groups suggest that, compared to phone-based support, mPCL may facilitate effective symptom-focused care in a more efficient and scalable manner. Study limitations include a small sample of patients from a single urban hospital and lack of a true usual care arm. Broader study of mPCL’s cost-efficiency and utility in Tanzania is needed. This work promises to close a large PC gap in under-resourced settings throughout Tanzania and other LMICs.
