Reduction in resource use with the misoprostol vaginal insert vs the dinoprostone vaginal insert for labour induction: a model-based analysis from a United Kingdom healthcare perspective.

BACKGROUND: In view of the increasing pressure on the UK's maternity units, new methods of labour induction are required to alleviate the burden on the National Health Service, while maintaining the quality of care for women during delivery. A model was developed to evaluate the resource use associated with misoprostol vaginal inserts (MVIs) and dinoprostone vaginal inserts (DVIs) for the induction of labour at term. METHODS: The one-year Markov model estimated clinical outcomes in a hypothetical cohort of 1397 pregnant women (parous and nulliparous) induced with either MVI or DVI at Southmead Hospital, Bristol, UK. Efficacy and safety data were based on published and unpublished results from a phase III, double-blind, multicentre, randomised controlled trial. Resource use was modelled using data from labour induction during antenatal admission to patient discharge from Southmead Hospital. The model's sensitivity to key parameters was explored in deterministic multi-way and scenario-based analyses. RESULTS: Over one year, the model results indicated MVI use could lead to a reduction of 10,201 h (28.9%) in the time to vaginal delivery, and an increase of 121% and 52% in the proportion of women achieving vaginal delivery at 12 and 24 h, respectively, compared with DVI use. Inducing women with the MVI could lead to a 25.2% reduction in the number of midwife shifts spent managing labour induction and 451 fewer hospital bed days. These resource utilisation reductions may equate to a potential 27.4% increase in birthing capacity at Southmead Hospital, when using the MVI instead of the DVI. CONCLUSIONS: Resource use, in addition to clinical considerations, should be considered when making decisions about labour induction methods. Our model analysis suggests the MVI is an effective method for labour induction, and could lead to a considerable reduction in resource use compared with the DVI, thereby alleviating the increasing burden of labour induction in UK hospitals.

Budget impact of rosuvastatin initiation in high-risk hyperlipidemic patients from a US managed care perspective.

INTRODUCTION: Statins reduce low-density lipoprotein cholesterol (LDL-C) levels, which, when elevated, represent a significant risk factor for cardiovascular (CV) disease. Hyperlipidemic patients at risk of CV events initiated on simvastatin or atorvastatin may be less likely to meet LDL-C goals (defined in National Cholesterol Education Program guidelines) and more likely to experience CV events than patients initiated on rosuvastatin. A 3-year budget impact model was developed to estimate the clinical impact and cost to a US managed care organization (MCO) with 1 million members of initiating high-risk hyperlipidemic patients on rosuvastatin rather than simvastatin or atorvastatin. METHODS: A total of 1000 adult patients were assumed to initiate statins. The average baseline LDL-C level was 189 mg/dL. In scenario 1, all patients were initiated on simvastatin or atorvastatin and titrated to a higher dose, or switched to atorvastatin (if initiated on simvastatin) or rosuvastatin; in scenario 2, 50% of the 520 high-risk patients were initiated on rosuvastatin. Drug acquisition and administration costs were considered. Product labeling, clinical trial results, national prescription claims data, and published literature were used to populate the model. RESULTS: Over 3 years, 75 additional patients reached their LDL-C goal in scenario 2, compared with scenario 1 (633 vs 558, respectively), at an increased cost of $240,628 ($1,415,516 vs $1,174,888, respectively). The additional per member per month (PMPM) cost of scenario 2 was $0.007. LIMITATIONS: This analysis assumed that statin efficacy is the same in real life as in trials, and used titration and switching patterns not based on patients' goal attainment. However, sensitivity and scenario analyses showed that the model was less sensitive to these parameters than to cost-related parameters. CONCLUSIONS: Initiating high-risk hyperlipidemic patients on rosuvastatin may increase the number of patients reaching LDL-C goal at a relatively modest increase in PMPM cost to an MCO.
