From Flying Surgeon to Permanent Hub: A Historical Vignette of Decentralised Neurosurgical Service Development in Rural East Coast Sabah.

Background: Access to neurosurgical care in remote regions remains challenging because of the uneven distribution of specialists, transportation limitations, and infrastructure constraints. For many years, patients from East Coast Sabah relied on transfer to Queen Elizabeth Hospital, Kota Kinabalu, for emergency and elective neurosurgical care, often requiring long-distance evacuation. This study describes the phased development of a decentralised neurosurgical service in Tawau and evaluates associated regional service trends. Methods: This descriptive historical vignette and service evaluation reviewed aggregated neurosurgical data from Tawau Hospital, Duchess of Kent Hospital (Sandakan), and Lahad Datu Hospital from 2019 through April 2026. Service activity was analysed across three phases: the flying surgeon model, rotational specialist postings, and permanent specialist deployment. Referrals, admissions, outpatient attendance, operative activity, interhospital transfers, and mortality were evaluated descriptively. Results: The East Coast Sabah Neurosurgical Service evolved from a monthly visiting service to rotational specialist coverage and, ultimately, a permanent Tawau-based hub in 2025. Referrals, outpatient attendance, and operative workload increased progressively across the three phases. Mean annual referrals increased from 1,388 to 1,802 and reached an annualised 2,130 during early Phase 3. Annual outpatient attendance increased from 1,117 to 1,675, with an annualised total of 2,526 visits. Operative volume increased from 202 to 366, with an annualised total of 374 procedures, while the proportion of elective procedures rose from 1.9% to 16.5%. Crude inpatient mortality rates were 5.8%, 4.9%, and 3.2% across the three phases. Following establishment of the permanent hub, emergency transfers from Tawau decreased from approximately 35 per year during Phase 2 to an annualised 18 per year during early Phase 3, corresponding to a crude administrative estimate of annual government cost avoidance of approximately RM425,000 to RM680,000 through reduced emergency air evacuations. Conclusion: The phased decentralisation of neurosurgical services in Tawau was associated with expanded local capacity, improved continuity of care, and reduced reliance on transfers to a tertiary referral centre for selected neurosurgical conditions.
