Economic evaluation of chronic disease self-management for people with diabetes: a systematic review.

AIMS: To systematically review the evidence on the costs and cost-effectiveness of self-management support interventions for people with diabetes. BACKGROUND: Self-management support is the provision of education and supportive interventions to increase patients' skills and confidence in managing their health problems, potentially leading to improvements in HbA1c levels in people with diabetes. METHODS: Randomized controlled trials, observational studies or economic modelling studies were eligible for inclusion in the review. The target population was adults with diabetes. Interventions had to have a substantial component of self-management support and be compared with routine care. Study quality was evaluated using the Consensus on Health Economic Criteria and International Society of Pharmacoeconomic Outcomes Research questionnaires. A narrative review approach was used. RESULTS: A total of 16 costing and 21 cost-effectiveness studies of a range of self-management support interventions were identified. There was reasonably consistent evidence across 22 studies evaluating education self-management support programmes suggesting these interventions are cost-effective or superior to usual care. Telemedicine-type interventions were more expensive than usual care and potentially not cost-effective. There was insufficient evidence regarding the other types of self-management interventions, including pharmacist-led and behavioural interventions. The identified studies were predominantly of poor quality, with outcomes based on short-term follow-up data and study designs at high risk of bias. CONCLUSIONS: Self-management support education programmes may be cost-effective. There was limited evidence regarding other formats of self-management support interventions. The poor quality of many of the studies undermines the evidence base regarding the economic efficiency of self-management support interventions for people with diabetes.

Economic evaluation of robot-assisted hysterectomy: a cost-minimisation analysis.

OBJECTIVE: The aim of this study was to carry out an economic evaluation of robot-assisted hysterectomy compared with the current standard of care in Ireland. DESIGN: Cost-minimisation analysis of robot-assisted hysterectomy compared with a combination of traditional open and conventional laparoscopic surgery. SETTING: The publicly funded healthcare system in Ireland. POPULATION: The target population was women requiring hysterectomy that could be completed using robot-assisted surgery. METHODS: A simulation-based economic evaluation model including data derived from a systematic review and local databases was used to estimate surgical costs. MAIN OUTCOME MEASURES: Incremental cost of robot-assisted surgery compared to current routine care. RESULTS: The incremental cost of robot-assisted hysterectomy is an estimated €3291 (95% confidence interval €2509-€4183) more than the existing mix of open and traditional laparoscopic surgery. The additional cost of robot-assisted surgery is primarily driven by the increased cost of surgical equipment, the robot, maintenance of the robot, and the cost of theatre staff due to longer operative times. The only significant factor reducing the cost of surgery is a shorter hospital stay relative to open surgery. CONCLUSIONS: Robot-assisted hysterectomy is more costly than the current mix of open and traditional laparoscopic surgery. Without longer-term or functional outcome data, the additional expense associated with robot-assisted hysterectomy may not be justified in a budget-constrained health system.
