From Effectiveness to Long-Term Impact. Sustainability of a Frugal Managed Surgical Consultation Network in Low-Income Settings: Evidence From Malawi.

Abstract

Background: Digital technology holds transformative potential to address barriers to safe and timely surgical expertise and surgery in low-resource settings, where shortages of specialists, fragmented referral systems, and limited infrastructure remain significant challenges. In 2018, Malawi launched a managed surgical clinical network (MCN) in the Southern region, utilizing a structured mobile technology platform to link non-specialist district clinicians with tertiary-level surgeons. Following the conclusion of donor funding in 2022, the MCN has continued to operate under full local stewardship. This study assesses the functionality and potential scalability of the network 1 year after this transition.

Methods: A prospective study was conducted of all district-to-central hospital MCN consultations between January and December 2023. Anonymized data were extracted from digital transcripts and analyzed descriptively and inferentially, including case characteristics, timing, clinician participation, and consultation outcomes.

Results: Over the 12 months, 994 cases were submitted by 158 district clinicians across 17 hospitals (mean 3 cases/day). Pediatric patients accounted for 47% of consultations. The most frequent presentations were acute abdomens (25%), trauma (22%), and congenital abnormalities (21%). Nearly 70% of cases included supporting images. Among the 811 consultations that required a response, 92% received specialist input, and 69% of the responses were provided within 1 h. Most cases (69%) resulted in a recommended referral, whereas 8% were managed locally with remote specialist guidance. Other outcomes included referral at a later stage (9%), forwarding to consultants outside of the MCN (3%), and an unknown conclusion (3%). In 183 cases, a referral notification was submitted without requiring a response. The MCN also supported professional learning and triggered social service mobilization in cases of suspected violence.

Conclusion: The Malawi Surgical MCN has evolved into a sustainable, locally owned platform supporting real-time decision-making, capacity building, and coordination of surgical care across district and central hospitals. Its continuation, after donor funding ended, demonstrates the feasibility of affordable, digitally enabled clinical networks in resource-constrained environments. The MCN is a potentially scalable model that could be used to strengthen surgical systems and reduce inequities in access to specialist care across sub-Saharan Africa and other similar contexts.
