Spine Trauma as a Component of Essential Neurosurgery: An Outcomes Analysis from Cambodia.

OBJECTIVE: In recent years, delivery of cost-effective "essential neurosurgery" in resource-limited communities has been recognized as an indispensable part of health care and a global health priority. The aim of this study was to review outcomes from operative management of spine trauma at a resource-limited government hospital in Phnom Penh, Cambodia, and to provide an epidemiologic report to guide prevention programs. METHODS: A retrospective review of a prospective neurosurgical database was performed to identify risk factors for spine trauma and severe spinal cord injury (American Spinal Injury Association A or American Spinal Injury Association B) and to evaluate the cost-effectiveness of surgery for patients treated at Preah Kossamak Hospital for subaxial and thoracolumbar spine trauma from 2013 to 2016. RESULTS: Surgical treatment was provided to 277 patients with cervical or thoracolumbar spine trauma, including 36 facet dislocations and 135 thoracolumbar burst fractures at a cost of $100-$280 per surgery. Six patients (2.2%) required treatment for postoperative wound infection. Reoperation was performed in 8 patients (2.9%) for wrong-level surgery. Failure of short-segment pedicle screw fixation was discovered in 4 patients (7.0%). Neurologic improvement was reported by 64 patients (65.3%) with incomplete spinal cord injury and available long-term follow-up. CONCLUSIONS: Affordable neurosurgical care can be provided in a safe and sustainable manner to patients with traumatic spine and spinal cord injuries in resource-limited communities. This supports the call for essential neurosurgery to be made available around the world to individuals from all socioeconomic strata.

Cost-Effectiveness of Craniotomy for Epidural Hematomas at a Major Government Hospital in Cambodia.

BACKGROUND: Epidural hematoma (EDH) is a common and potentially deadly occurrence following a severe traumatic brain injury. Our aim was to determine whether craniotomy is cost-effective when indicated for the treatment of EDH when a trained neurosurgeon is available. METHODS: A decision tree was used to model the cost-effectiveness of craniotomy available versus craniotomy unavailable for the management of traumatic EDH from a Cambodian societal and provider perspective. Costs and effectiveness parameters were obtained from patient data at a large government hospital in Cambodia. Outcomes were measured in quality-adjusted life years (QALYs). Incremental cost per QALY and budget impact were calculated for each intervention at a willingness-to-pay (WTP) threshold of $9787.80/QALY (3× GDP per capita PPP). The time horizon reflected full life span, and costs and QALYs were discounted at 3%. Sensitivity analysis was also conducted. RESULTS: Compared to craniotomy unavailable for EDH ($945.80; 11.78 QALYs), craniotomy available came at a higher cost and greater effectiveness ($1520.73; 12.78 QALYs), resulting in an incremental cost-effectiveness ratio (ICER) of $574.93. One-way analysis demonstrated that craniotomy unavailable became more cost-effective than craniotomy available when the percent chance of having a GOS of 4 or 5 was 60% for patients with an EDH where craniotomy was indicated but not performed. Probabilistic sensitivity analysis revealed that craniotomy available was more cost-effective than conservative management in 84.4% of simulations at the WTP threshold. CONCLUSIONS: Craniotomy is a cost-effective treatment for patients with a traumatic EDH who meet criteria for operation when trained neurosurgeons are available onsite.
