Early neurologically focused follow-up after cardiac arrest is cost-effective: A trial-based economic evaluation

ObjectiveTo evaluate the cost-effectiveness of an early intervention service for cardiac arrest survivors called 'Stand still …, and move on' from a societal perspective.InterventionThis concise nursing intervention consists of screening for cognitive and emotional problems, information provision and support, self-management promotion, and further referral if necessary. Earlier research confirmed the feasibility of the intervention and its effectiveness in improving emotional functioning and quality of life.MethodsIn this multicentre randomized controlled trial with one year follow-up 185 patients were included between April 2007 and December 2010. The experimental group received the intervention, the control group received care-as-usual. Intervention costs, other direct healthcare costs (e.g. hospital care, rehabilitation, medication, home care) and indirect costs (productivity loss) were measured during ten months using monthly cost-diaries. The economic evaluation comprised a cost-utility analysis (SF-36) and a cost-effectiveness analysis (QOLIBRI) using bootstrapping (5000 replications) to quantify uncertainty concerning the incremental cost effectiveness ratio (ICER), and the probability of the intervention being cost-effective was estimated. To check the robustness of the findings, two sensitivity analyses were performed using the EQ-5D and the complete cases respectively.ResultsOf 136 (74%) participants sufficient data concerning costs were collected to be included in this economic evaluation. Intervention costs were on average €127 (SD 85). No significant differences between groups were found with regard to overall costs. The ICERs of the cost-utility and the cost-effectiveness analyses supported the cost-effectiveness of the intervention. The probability of the intervention being cost-effective was 54-76% for the SF-36 and 94% for the QOLIBRI. Findings were robust.ConclusionThe intervention 'Stand still …, and move on' has positive societal economic effects and has a high probability to be cost-effective. Implementation in regular healthcare is recommended.Trial registrationISRCTN74835019.
