Rapport (övrigt vetenskapligt/konstnärligt)abstract
- How to allocate resources in the health care sector is academically dealt with within the subject of health economics. Economic evaluations are within this area used to compare the costs and effects of medical interventions with the purpose to help decision makers decide how to allocate resources.Oxygen deficiency in the foetus during birth can lead to severe life long injuries in the child. In high-risk deliveries, there is therefore considered necessary to use foetal surveillance with a scalp electrode and the choice is between surveillance with internal cardiotocography (CTG) and surveillance with ST analysis. The standard procedure is in most hospitals currently CTG, which records the foetal heart rate and the uterine contractions. The second strategy, in this thesis referred to as ST analysis, complements CTG with foetal electrocardiography (ECG) and ST analysis.The objective of this report is to from a societal perspective determine the costeffectiveness of using ST analysis in complicated deliveries, compared to the use of CTG alone. A cost-utility analysis was performed based on a probabilistic decision model incorporating the relevant strategies and outcomes. The costs and effects of the two different treatment strategies were compared in a decision tree. Discounted costs and quality-adjusted life-years (QALYs) were measured and simulated over a life-time perspective.The analysis resulted in an incremental effect of 0.005 QALYs for the ST analysis strategy, when compared to the CTG strategy. ST analysis was also associated with a €30 lower cost. Thus, CTG is dominated by the ST analysis strategy. The probability that ST analysis is the cost-effective alternative is high for all values of willingness-to-pay for a QALY, which means that a decision to implement the ST analysis strategy based on the results of this thesis would be surrounded by a low degree of uncertainty.

- Objective: To assess the cost-effectivness of the use of cardiotocography (CTG) complemented with fetal electrocardiography and ST analysis compared with the use of CTG alone in term deliveries when a decision has been made to use fetal monitoring with a scarlp electrode. Design: A cost-effectiveness analysis based on a probabilistic decision model incorporating relevant strategies and lifelong outcomes. Setting: Maternity wards in Sweden. Population: Women with term fetuses after a clinical decision had been made to apply a fetal scalp electrode for internal CTG. Methods: A decision model was used to compare the costs and effects of two different treatment strategies. Baseline estimates were derived from the literature. Discounted costs and quality-adjusted life years (QALYs) were simulated over a lifetime horizon using a probabilistic model. Main outcome measures: QALYs, incremental costs, and cost per QALY gained expressed as incremental cost-effectiveness ratio (ICER). Results: The analysis found an incremental effect of 0.005 QALYs for ST analysis compared with CTG; the ST analysis strategy was also moreover associated with a -56 decrease in costs, thus dominating the CTG strategy. The probability that ST analysis is cost-effective in comparison with CTG is high, irrespective of the willingness-to-pay value for a QALY. Conclusions: Compared with CTG alone, ST analysis is cost-effective when used in term high-risk deliveries in which there is a need for internal fetal monitoring.
