Aim To estimate the price sensitivity of consumer choice of health insurance firm. Method Using paneldata of the flows of insured between pairs of Dutch sickness funds during the period 1993–2002, we estimate the sensitivity of these flows to differences in insurance premium. Results The price elasticity of residual demand for health insurance was low during the period 1993–2002, confirming earlier findings based on annual changes in market share. We find small but significant elasticities for basic insurance but insignificant elasticities for supplementary insurance. Young enrollees are more price sensitive than older enrollees. Conclusion Competition was weak in the market for health insurance during the period under study. For the market-based reforms that are currently under way, this implies that measures to promote competition in the health insurance industry may be needed.
SummaryThe paper uses unique data on contracts concluded by providers of home care to evaluate the effect of provider market power on prices of home care services in the Netherlands. Since, at least in some regions, one or two providers dominate the market, there are concerns about the effect of providers' market power on the pricing of home care services. Using data on contracted prices and quantities for 2004-2006, we find that providers with a larger market share are able to contract at a higher price. The effect remains after controlling for quality.
What factors determine how well consumers make their actual choices with regard to financial products? This article empirically evaluates two different choices consumers make when buying deferred annuities. One choice concerns the type of insurance policy, the other concerns the choice of insurance provider. For both choices, we will analyse what factors explain the quality of the choice made. In particular, we will investigate the role of financial advice in the decision-making process. By combining Dutch consumer survey data and data on quotations by Dutch life insurance companies, we obtain the following results. First, respondents who buy their policy directly from an insurer attain a significantly better match between their risk preferences and the type of policy chosen than respondents who purchase their policy through an insurance broker. Second, respondents who buy their policy through an insurance broker obtain a significantly lower payout than respondents who purchased their policy directly from an insurance company. These results raise doubts about the functioning of both the market for financial advice and the market for life insurances.
The pregnancy outcome of 1936 women who had transcervical chorionic villus sampling (CVS) with a flexible biopsy forceps was evaluated. Follow-up until 4 weeks after delivery was 99.4 per cent. Various patient- and procedure-related risk factors for spontaneous loss (fetal or neonatal death) were analysed using stepwise logistic regression analysis. The overall spontaneous loss rate was 4.5 per cent. Factors found to be significantly associated with spontaneous loss were quantity of villi < or = 15 mg (relative risk (RR) 2.13), a history of first-trimester miscarriage (RR 1.87) or delivery between 16 and 27 weeks (RR 3.87), cervical culture positive for anaerobes (RR 4.52) or group B streptococcus (RR 3.62), post-procedural bleeding > 3 days (RR 1.99), and multiple insertions (RR 2.64). Significant differences in loss rates between individual operators were found. A learning effect was not present. There were no infants born with terminal transversal limb anomalies in our series. We conclude that knowledge about significant risk factors for spontaneous loss after CVS is important both for obstetricians carrying out CVS procedures and for women seeking prenatal diagnosis.
Aims
Screening for atrial fibrillation (AF) is recommended by the European Society of Cardiology guideline to prevent strokes. Cost-effectiveness analyses of different screening programs for AF are difficult to compare, because of varying settings and models used. We compared the impact and cost-effectiveness of various AF screening programs in the Netherlands.
Methods and results
The base case economic analysis was conducted from the societal perspective. Health effects and costs were analysed using a Markov model. The main model inputs were derived from the ARISTOTLE, RE-LY and ROCKET AF trial combined with Dutch observational data. Univariate, probabilistic sensitivity and various scenario analyses were performed. The maximum number of newly detected AF patients in The Netherlands ranged from 4554 to 39 270, depending on the screening strategy used. Adequate treatment with anticoagulation would result in a maximum of more than 3000 strokes prevented using single time point AF screening. Compared with no screening, screening 100 000 persons provided a gain in QALYs ranging from 984 to 8727, and a mean cost difference ranging from -6650 000€ to 898 000€, depending on the screening strategy used. Probabilistic sensitivity analysis (PSA) demonstrated a 100% likelihood that screening all patients ≥ 75 years visiting the Geriatric outpatient clinic was cost-saving. Four out of six strategies were cost-saving in ≥ 74% of the PSA simulations. Out of these, opportunistic screening of all patients ≥ 65 years visiting the GPs office had the highest impact on strokes prevented.
Conclusion
Most single-time point AF screening strategies are cost-saving and have an important impact on stroke prevention.
