ObjectSurgical intervention for appropriately selected patients with cervical spondylotic myelopathy (CSM) has demonstrated favorable outcomes. This study evaluates the cost-effectiveness of this type of surgery in terms of cost per quality-adjusted life year (QALY) gained.MethodsAs part of a larger prospective multicenter study, the direct costs of medical treatment for 70 patients undergoing surgery for CSM at a single institution in Canada were retrospectively obtained from the hospital expenses database and physician reimbursement data. Utilities were estimated on the entire sample of 278 subjects enrolled in the multicenter study using SF-6D–derived utilities from 12- and 24-month SF-36v2 follow-up information. Costs were analyzed from the payer perspective. A 10-year horizon with 3% discounting was applied to health-utilities estimates. Sensitivity analysis was performed by varying utility gain by 20%.ResultsThe SF-6D utility gain was 0.0734 (95% CI 0.0557–0.0912, p < 0.01) at 12 months and remained unchanged at 24 months. The 10-year discounted QALY gain was 0.64. Direct costs of medical treatment were estimated at an average of CaD $21,066. The estimated cost-utility ratio was CaD $32,916 per QALY gained. The sensitivity analysis showed a range of CaD $27,326–$40,988 per QALY gained. These estimates are within the limits for medical procedures that have an acceptable cost-utility ratio.ConclusionsSurgical treatment for CSM is associated with significant improvement in health utilities as measured by the SF-6D. The direct cost of medical treatment per QALY gained places this form of treatment within the category deemed by payers to be cost-effective.
We report a case of a 22-year-old man presenting with a fourth ventricular tumour and associated chronic obstructive hydrocephalus likely leading to thinning of the cranium. Intraoperatively, he developed an epidural hematoma secondary to a fracture of the temporal bone by application of the three-point skull fixator. This is the second reported adult case of an iatrogenic epidural hematoma secondary to pin-site complications. We advocate the careful placement of the pins and suggest the tightening force be catered individually especially in pediatric patients or patients with chronic hydrocephalus.
Intracranial Hodgkin's lymphoma (ICHL) in the HIV positive population is a rarely reported event with only three prior cases reported in the literature. In these prior reports, the outcome of the patients was uncertain or very poor. We report here the case of an HIV seropositive patient with an isolated intracranial recurrence of Hodgkin's Lymphoma (HL) who achieved long-term control of his cranial disease and continues to have a high performance status more than 3 years following treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
