Background It is generally understood that the profile of spine surgery varies by setting, based on factors such as the age profile of the population, the economic context and access to healthcare. Relatively little is known about the profile of spine surgery in South Africa, although one previous report from the public healthcare sector suggested a high burden of trauma and infection-related surgery. To our knowledge, there has been no formal investigation in the private sector. A holistic understanding of spine surgery within our setting may be beneficial for applications such as resource allocation and informing the training needs of future specialists. Objectives To provide insight into spinal surgery in the South African private healthcare sector by describing spine surgery characteristics within a large open medical scheme, including both patient and surgeon profiles. Methods This retrospective review included adult inpatient spine surgeries funded by the largest open medical scheme in South Africa between 2008 and 2017. An anonymized dataset extracted from the scheme records included patient demographics, ICD-10 codes, procedure codes and surgeon specialization. Descriptive patient and surgery data were presented. Furthermore, the association between patient and surgery factors and surgeon specialization was investigated using univariate and multivariate analyses. Results A total of 49,576 index spine surgeries were included. The largest proportion of surgeries involved members 40-59 years old (n=23,543, 48%), approximately half involved female members (n=25,293, 51%) and most were performed by neurosurgeons (n=35,439, 72%). At least 37,755 (76%) surgeries were for degenerative pathology, 2,100 (4%) for trauma and 242 (0.5%) for infection. Adjusted risk ratios (aRR) significantly associated with orthopaedic surgeon specialization included cervical spine region aRR = 0.49 (95% C.I. 0.39-0.61), trauma aRR = 1.50 (95% C.I. 1.20-1.88), deformity aRR = 1.77 (95% C.I. 1.33-2.35) and blood transfusion aRR = 1.46 (95% C.I. 1.12-1.91). Conclusion Spine surgery in South Africa’s largest open medical scheme was dominated by surgery for degenerative pathology in older adults and was performed largely by neurosurgeons. This constituted a stark contrast to a previous report from the public sector and highlighted a mismatch between exposure during public sector registrar training and private practice post-specialization. The findings support the need for private-public collaboration as well as the importance of spine fellowships for all specialists intending to practice spine surgery.

BACKGROUND: Spinal pathology in the Western Cape is managed at three tertiary level hospitals, including Tygerberg Hospital. The Tygerberg Hospital Orthopaedic Spinal Unit is responsible for the management of spinal pathology for the 3.4 million people in the hospital's catchment area. However, the unit's overall burden of disease and associated resource use is currently unclear AIM: The first aim was to investigate the overall burden and clinical profile of spinal pathology presenting to the Tygerberg Hospital Spinal Unit over a one-year period. The second aim was to determine resource use associated with spine pathology admissions METHODS: Overall burden was investigated by performing a retrospective review of all patients admitted to the Spine Unit between 1 October 2016 and 30 September 2017. Demographic and clinical data was collected, and patients were assigned to one of Ave spinal pathology sub-groups. Resource use was determined by length of hospital stay, waiting times, advanced imaging and theatre usage RESULTS: Overall burden comprised 349 individual patients and 376 admissions, including readmissions. Trauma (51%) and infection (24%) accounted for the majority of admitted pathology with degenerative (10%), deformity (7%) and malignancy (7%) representing fewer admissions. Motor vehicle accidents were the primary mechanism of injury, accounting for 48% of spine trauma. Tuberculosis was the causative organism in 87% of spinal infections with 44% HIV co-infection. Hospital resource use was considerable with 92% of spine patients requiring advanced imaging, a median operating time of 3 h 36 min and a median hospital stay of 19 days. Infection and malignancy sub-groups had the longest waiting times for advanced imaging and theatre with a median wait of 14-16 days, accounting for approximately 62% of the typical total hospital stay CONCLUSIONS: The Spine Unit experienced a substantial patient burden requiring significant hospital resources. Reduced in-patient waiting times and upskilling of orthopaedic services at secondary hospitals represent key areas for health system strengthening. However, multi-sectoral strategies would be required to effectively address our high burden of largely preventable spinal pathology Level of evidence: Level 4
