RATIONALE: Obesity is the most important risk factor for obstructive sleep apnea (OSA). However, although included in clinical guidelines, no randomized controlled studies have been performed on the effects of weight reduction on mild OSA. OBJECTIVES: The aim of this prospective, randomized controlled parallel-group 1-year follow-up study was to determine whether a very low calorie diet (VLCD) with supervised lifestyle counseling could be an effective treatment for adults with mild OSA. METHODS: Seventy-two consecutive overweight patients (body mass index, 28-40) with mild OSA were recruited. The intervention group (n = 35) completed the VLCD program with supervised lifestyle modification, and the control group (n = 37) received routine lifestyle counseling. The apnea-hypopnea index (AHI) was the main objectively measured outcome variable. Change in symptoms and the 15D-Quality of Life tool were used as subjective measurements. MEASUREMENTS AND MAIN RESULTS: The lifestyle intervention was found to effectively reduce body weight (-10.7 +/- 6.5 kg; body mass index, -3.5 +/- 2.1 [mean +/- SD]). There was a statistically significant difference in the mean change in AHI between the study groups (P = 0.017). The adjusted odds ratio for having mild OSA was markedly lowered (odds ratio, 0.24 [95% confidence interval, 0.08-0.72]; P = 0.011) in the intervention group. All common symptoms related to OSA, and some features of 15D-Quality of Life improved after the lifestyle intervention. Changes in AHI were strongly associated with changes in weight and waist circumference. CONCLUSIONS: VLCD combined with active lifestyle counseling resulting in marked weight reduction is a feasible and effective treatment for the majority of patients with mild OSA, and the achieved beneficial outcomes are maintained at 1-year follow-up.

Objective: A novel preoperative procedure From Home To Operation (FHTO) seeks to combat increasing operation and infection rates. This is the first prospective randomized controlled trial (RCT) comparing the cost-effectiveness and cost-utility of FHTO and conventional ward procedures for standardized Laparoscopic Cholecystectomy (LC).Research Design and Methods: During 12/2004-7/2005, 47 patients with symptomatic gallstones were randomized to receive LC in the FHTO (28 patients) or in a conventional manner (19 patients) in a Finnish hospital setting. The 15D quality of life tool was administered at the baseline and 1 month after.Main Outcome Measures: A stochastic approach over a month interval for hospital costs, length of postoperative stay, infection rate and Quality-Adjusted Life Years (QALY) was employed.Results: Baseline group characteristics were similar. The mean health care costs with FHTO (1695 EUR) were significantly lower (p < 0.001) than in the conventional arm (2234 EUR). The number of patients discharged on the first postoperative day was 27 (96.4%) and 15 (78.9%) with two (7.1%) infections in the FHTO and four (21.1%) in the conventional arm. A difference in QALYs gained (0.0174; p = 0.030) favouring FHTO was observed. According to a cost-effectiveness acceptability curve, the probability of FHTO being cost-effective was 99%. The results were robust to probabilistic sensitivity analyses.Conclusions: FHTO can introduce substantial cost savings and have a positive impact on both clinical measures and quality of life. Studies with larger numbers of patients are needed to assess whether conventional ward procedure can be a source of infections, which can be avoided with FHTO.Clinical Trial Registry: ICJME-qualified registry of the Hospital District of Helsinki and Uusimaa (number 217849).

Background: To reduce the risk of thromboembolic complications, clinical guidelines recommend anticoagulation treatment for almost all atrial fibrillation (AF) patients. Although warfarin has long been the primary treatment alternative, now newer alternatives such as apixaban have proven effective in prevention of the thromboembolic complications of non-valvular AF. The aim of this study is to assess the cost-effectiveness of apixaban when compared with warfarin in the prevention of AF-associated thromboembolic complications in Finland., Methods: The assessment was performed with a lifetime Markov-model with the following health states: non-valvular AF, ischemic stroke, hemorrhagic stroke, other intracranial bleed, other major bleed, clinically relevant non-major bleed, myocardial infarction, and systemic embolism. The treatment efficacies were obtained from the ARISTOTLE trial. Representative Finnish input data were used for the model states, including background mortality, resource use, costs (in 2014 values), and EQ-5D-3L-based quality of life. The results (with 3 % annual discounting) are presented as incremental cost-effectiveness ratios [ICER, cost per quality-adjusted life year (QALY) gained], the expected value of perfect information (EVPI), and the probability of apixaban being cost-effective at various willingness-to-pay levels., Results: Apixaban increased life-expectancy by 0.17 years and quality-adjusted life-expectancy by 0.14 QALYs when compared with warfarin. Additional QALY was gained with apixaban at a cost of 1824 euros based on the deterministic analysis. The maximum EVPI was 649 euros/patient at 1282 euros per QALY gained in the probabilistic analysis. The probability of apixaban being cost-effective reached 80 % when the willingness-to-pay per QALY gained was 14,857 euros. In deterministic sensitivity analyses, ICERs varied from dominance of apixaban to additional QALY being gained at a cost of 12,312 euros., Conclusions: The ICERs obtained were well below the WHO-CHOICE threshold values for cost-effective interventions, suggesting that apixaban is a very cost-effective treatment alternative for warfarin in Finnish patients with AF.

Introduction: Cost-utility assessment of first-line actinic keratosis (AK) treatments for max 25 cm2 AK field., Methods: A probabilistic, 2-year decision tree model was used to assess costs, quality-adjusted life-years (QALY), incremental cost-effectiveness ratio (ICER), cost-effectiveness efficiency frontier, cost-effectiveness acceptability frontier (CEAF), and expected value of perfect information (EVPI) of AK treatments from the Finnish health care payer perspective with 3% discounting per annum. In the model, the first-line AK treatment resulted in complete clearance (CC) or non-CC with or without local skin responses (LSR), or AK recurrence. Non-CC AK was treated with methyl aminolevulinate+photodynamic therapy (MAL+PDT), and AK recurrence was retreated with the previous effective treatment. Costs included primary and secondary health care, outpatient drugs, and LSR management. QALYs were assessed with the EuroQol (EQ-5D-3L). Result robustness was assessed with sensitivity analyses., Results: The mean simulated per patient QALYs (costs) were 1.526 (€982) for MAL+PDT, 1.524 (€794) for ingenol mebutate gel (IngMeb) 0.015% (3 days), 1.522 (€869) for IngMeb 0.05% (2 days), 1.520 (€1062) for diclofenac 3% (12 weeks), 1.518 (€885) for imiquimod 3.75% (6 weeks), 1.517 (€781) for imiquimod 5% (4/8 weeks), and 1.514 (€1114) for cryosurgery when treating AK affecting any body part. IngMeb 0.015% was less costly and more effective (dominating) than other AK treatments indicated for face and scalp area with the exception of imiquimod 5% for which the ICER was estimated at €1933/QALY gained and MAL+PDT, which had an ICER of €82,607/QALY gained against IngMeb 0.015%. With willingness-to-pay €2526-18,809/QALY gained, IngMeb 0.015% had >50% probability for cost-effectiveness on the CEAF. IngMeb 0.05% dominated AK treatments indicated for trunk and extremities. EVPIs for face and scalp (trunk and extremities) analyses were €26 (€0), €86 (€58), and €250 (€169) per patient with the willingness-to-pay of €0, €15,000, and €30,000 per QALY gained, respectively., Conclusion: IngMebs were cost-effective AK treatments in Finland., Funding: LEO Pharma.

Rationale, Aims and Objectives: Invasive pneumococcal diseases (IPD) are associated with substantial burden in adults (≥50 years). Moreover, adults with vascular, metabolic or respiratory diseases have been shown to have a 3-6 times higher risk of IPD when compared with their healthy controls. These persons at higher risk are likely to benefit most from pneumococcal vaccinations. The 13-valent pneumococcal conjugate vaccine (PCV13) was recently introduced to prevent the 13 most prevalent serotypes causing invasive pneumococcal disease in adults. The objective of this study was to estimate the expected 5-year economic impact of targeted PCV13 vaccination compared with no vaccination in Finnish adults (≥50 years) at moderate or high risk for IPD., Methods: A budget impact model was developed to predict the impact of PCV13 vaccination in terms of the costs and IPD events avoided for years 2012-2016., Results: Approximately 35% of the 2.2 million Finns over 50 years of age can be considered to be at moderate or high risk for IPD because of underlying chronic medical conditions. Vaccination of these people with PCV13 could provide an estimated net budget savings of about €218 million compared with the current no-vaccination situation over the next 5 years. Among the risk groups considered, the largest absolute net savings (€66.2 million) could be expected to be obtained by vaccinating people with heart disease, due to its high prevalence in the target population., Conclusion: In Finland, the immunization with PCV13 vaccine, of adults (≥50 years) at moderate and high risk of IPD, is estimated to lead to substantial cost savings in the 5 years after vaccination., (© 2014 John Wiley & Sons, Ltd.)

Objective: To assess the frequency of warfarin use, the achieved international normalised ratio (INR) balance among warfarin users and the primary healthcare outpatient costs of patients with atrial fibrillation (AF)., Design: Retrospective, non-interventional registry study., Setting: Primary healthcare., Participants: All patients with AF (n=2746) treated in one Finnish health centre between October 2010 and March 2012., Methods: Data on healthcare resource use, warfarin use, individually defined target INR range and INR test results were collected from the primary healthcare database for patients with AF diagnosis. The analysed dataset consisted of a 1-year follow-up. Warfarin treatment balance was estimated with the proportion of time spent in the therapeutic INR range (TTR). The cost of used healthcare resources was valued separately with national and service provider unit costs to estimate the total outpatient treatment costs. The factors potentially impacting the treatment costs were assessed with a generalised linear regression model., Results: Approximately 50% of the patients with AF with CHADS-VASc ≥1 used warfarin. The average TTR was 65.2% but increased to 74.5% among patients using warfarin continuously (ie, without gaps exceeding 56 days between successive INR tests) during follow-up. One-third of the patients had a TTR of below 60%. The average outpatient costs in the patient cohort were €314.44 with the national unit costs and €560.26 with the service provider unit costs. The costs among warfarin users were, on average, €524.11 or €939.54 higher compared with the costs among non-users, depending on the used unit costs. A higher TTR was associated with lower outpatient costs., Conclusions: The patients in the study centre using warfarin were, on average, well controlled on warfarin, yet one-third of patients had a TTR of below 60%.

Background: Cost-effectiveness studies explicitly reporting infusion times, drug-specific administration costs for infusions or real-payer intravenous drug cost are few in number. Yet, administration costs for infusions are needed in the health economic evaluations assessing intravenously-administered drugs., Objectives: To estimate the drug-specific administration and total cost of biologic intravenous rheumatoid arthritis (RA) drugs in the adult population and to compare the obtained costs with published cost estimates., Methods: Cost price data for the infusions and drugs were systematically collected from the 2011 Finnish price lists. All Finnish hospitals with available price lists were included. Drug administration and total costs (administration cost + drug price) per infusion were analysed separately from the public health care payer's perspective. Further adjustments for drug brand, dose, and hospital type were done using regression methods in order to improve the comparability between drugs. Annual expected drug administration and total costs were estimated. A literature search not limited to RA was performed to obtain the per infusion administration cost estimates used in publications. The published costs were converted to Finnish values using base-year purchasing power parities and indexing to the year 2011., Results: Information from 19 (95%) health districts was obtained (107 analysable prices out of 176 observations). The average drug administration cost for infliximab, rituximab, abatacept, and tocilizumab infusion in RA were €355.91; €561.21; €334.00; and €293.96, respectively. The regression-adjusted (dose, hospital type; using semi-log ordinary least squares) mean administration costs for infliximab and rituximab infusions in RA were €289.12 (95% CI €222.61-375.48) and €542.28 (95% CI €307.23-957.09). The respective expected annual drug administration costs were €2312.96 for infliximab during the first year, €1879.28 for infliximab during the forthcoming years, and €1843.75 for rituximab. The obtained average administration costs per infusion were higher (1.8-3.3 times depending on the drug) than the previously published purchasing power adjusted and indexed average administration costs for infusions in RA., Conclusions: The administration costs of RA infusions vary between drugs, and more effort should be made to find realistic drug-specific estimates for cost-effectiveness evaluations. The frequent assumption of intravenous drug administration costs equalling outpatient visit cost can underestimate the costs.
