ABSTRACT
PURPOSE: To estimate the incidence of instrumental spinal surgeries (ISS) and consecutive reoperations and to calculate the related resource utilization and costs. METHODS: ISS and subsequent reoperations were identified retrospectively using surgery codes in claims data. The study period included January 01, 2009 to December 31, 2011. The reoperation rate was calculated for 1 year after the primary ISS. Resource utilization and costs were analyzed by group comparison. RESULTS: A total of 3316 incident ISS patients were identified in 2010 with an annual reoperation rate of 9.98% (95% CI 8.98-11.02%). Mean costs per patient were 11,331 per ISS and 11,370 per reoperation, with 8432 directly attributed to the reoperation and 2938 to additional resources. CONCLUSIONS: Costs of ISS and subsequent reoperations have a significant impact on health insurances budgets. The annual cost of reoperations exceeds the direct cost of the primary surgery driven by the need for further inpatient and outpatient care.

Parkinson's disease (PD) is a complex progressive movement disorder leading to motor and non-motor symptoms that become increasingly debilitating as the disease advances, considerably reducing quality of life. Advanced treatment options include deep brain stimulation (DBS). While clinical effectiveness of DBS has been demonstrated in a number of randomised controlled trials (RCT), evidence on cost-effectiveness is limited. The cost-effectiveness of DBS combined with BMT, versus BMT alone, was evaluated from a UK payer perspective. Individual patient-level data on the effect of DBS on PD symptom progression from a large 6-month RCT were used to develop a Markov model representing clinical progression and capture treatment effect and costs. A 5-year time horizon was used, and an incremental cost-effectiveness ratio (ICER) was calculated in terms of cost per quality-adjusted life-years (QALY) and uncertainty assessed in deterministic sensitivity analyses. Total discounted costs in the DBS and BMT groups over 5 years were £68,970 and £48,243, respectively, with QALYs of 2.21 and 1.21, giving an incremental cost-effectiveness ratio of £20,678 per QALY gained. Utility weights in each health state and costs of on-going medication appear to be the key drivers of uncertainty in the model. The results suggest that DBS is a cost-effective intervention in patients with advanced PD who are eligible for surgery, providing good value for money to health care payers.

Different inhaled corticosteroids can be used to treat asthma but their relative efficacy on quality of life and relative economic impact are mostly unknown. A decision model compared the cost-utility of beclomethasone, beclomethasone-extrafine, fluticasone and budesonide in adult patients with either moderate or severe persistent asthma. The patients' health state was described by the Asthma Symptom Utility Index. Patients' consumption of healthcare resources, according to the health state, was elicited by a Delphi Panel. Within 2 months, beclomethasone-extrafine prolonged quality-adjusted life by 0.5-2.3 days, as compared with the other inhaled corticosteroids, and reduced asthma-related per patient costs by euro12-67.
