Pushing the boundaries of viability: the economic impact of extreme preterm birth.
BACKGROUND: Previous assessments of the economic impact of preterm birth focussed on short term health service costs across the broad spectrum of prematurity. OBJECTIVE: To estimate the societal costs of extreme preterm birth during the sixth year after birth. METHODS: Unit costs were applied to estimates of health, social and broader resource use made by 241 children born at 20 through 25 completed weeks of gestation in the United Kingdom and Republic of Ireland and a comparison group of 160 children born at full term. Societal costs per child during the sixth year after birth were estimated and subjected to a rigorous sensitivity analysis. The effects of gestational age at birth on annual societal costs were analysed, first in a simple linear regression and then in a multiple linear regression. RESULTS: Mean societal costs over the 12 month period were 9541 pounds sterling (standard deviation 11,678 pounds sterling) for the extreme preterm group and 3883 pounds sterling (1098 pounds sterling) for the term group, generating a mean cost difference of 5658 pounds sterling (bootstrap 95% confidence interval: 4203 pounds sterling, 7256 pounds sterling) that was statistically significant (P<0.001). After adjustment for clinical and sociodemographic covariates, sex-specific extreme preterm birth was a strong predictor of high societal costs. CONCLUSION: The results of this study should facilitate the effective planning of services and may be used to inform the development of future economic evaluations of interventions aimed at preventing extreme preterm birth or alleviating its effects.

Preference-based approaches to measuring the benefits of perinatal care.
Studies that measure benefits of health care interventions in natural or physical units cannot incorporate the several health changes that might occur within a single measure, and they overlook individuals' preferences for those health changes. This paper discusses and critically appraises the application of preference-based approaches to the measurement of the benefits of perinatal care that have developed out of economic theory. These include quality adjusted life year (QALY)-based approaches, monetary-based approaches, and discrete choice experiments. QALY-based approaches use scaling techniques, such as the rating scale, standard gamble approach, and time trade-off approach, or multi-attribute utility measures, to measure the health-related quality of life weights of health states. Monetary-based approaches include the revealed preference approach, which involves observing decisions that individuals actually make concerning health risks, and the willingness-to-pay approach, which provides a framework for investigating individuals' willingness to pay for benefits of health care interventions. Discrete choice experiments describe health care interventions in terms of their attributes, and elicit preferences for scenarios that combine different levels of those attributes. Empirical examples are used to illustrate each preference-based approach to benefit measurement, and several methodological issues raised by the application of these approaches to the perinatal context are discussed. Particular attention is given to identifying the relevant attributes to incorporate into the measurement instrument, appropriate respondents for the measurement exercise, potential sources of bias in description and valuation processes, and the practicality, reliability, and validity of alternative measurement approaches. The paper's conclusion is that researchers should be explicit and rigorous in their application of preference-based approaches to benefit measurement in the context of perinatal care.

Sevelamer.
Hyperphosphataemia in patients with chronic renal failure has traditionally been treated with calcium- and aluminium-containing phosphate binders. This article briefly discusses the rationale and complications of these treatments and reviews sevelamer that is a novel non-calcium-, non-aluminium-containing phosphate binder and the evidence to support its use in clinical practice.

The impact of preterm birth on hospital inpatient admissions and costs during the first 5 years of life.
OBJECTIVES: To compare the cumulative use and cost of hospital inpatient services to 5 years of age by individuals divided into 4 subgroups by gestational age at birth. DESIGN: Costs applied to the hospital service utilization profile of each infant born in 2 areas covered by the Oxford Record Linkage Study during 1970-1993. SETTING: Oxfordshire and West Berkshire, southern United Kingdom. SUBJECTS: 239 694 individuals divided into 4 subgroups by gestational age at birth: <28 weeks, 28 to 31 weeks, 32 to 36 weeks, >or=37 weeks. MAIN OUTCOME MEASURES: Number and duration of hospital admissions during the first 5 years of life and costs, expressed in pound sterling and valued at 1998-1999 prices, of hospital inpatient services. RESULTS: The total duration of hospital admissions for infants born at <28 and at 28 to 31 gestational weeks was 85 and 16 times that for term infants, respectively, once duration of life had been taken into account. Hospital inpatient service costs were significantly higher for preterm infants than for term infants, with the cost differences persisting throughout infancy and early and mid-childhood. Over the first 5 years of life, the adjusted mean cost difference was estimated at pound 14,614 ( 22,798 US dollars) when infants born at <28 weeks gestational age were compared with term infants and pound 11,958 ( 18,654 US dollars) when infants born at 28 to 31 weeks gestational age were compared with term infants. Independent contributions to total cost came from being born: small for gestational age, a multiple, during the 1970s and early 1980s, to a woman of extreme maternal age or who was hospitalized antenatally, and from experiencing extended survival or childhood disease. However, preterm birth remained the strongest predictor of high cost. CONCLUSIONS: Preterm birth is a major predictor of how much an individual will cost hospital service providers during the first 5 years of life.

Women's views of pregnancy ultrasound: a systematic review.
BACKGROUND: Ultrasound has become a routine part of care for pregnant women in most countries with developed health services. It is one of a range of techniques used in screening and diagnosis, but it differs from most others because of the direct access that it gives parents to images of the fetus. A review of women's views of ultrasound was commissioned as part of a larger study of the clinical and economic aspects of routine antenatal ultrasound use. METHODS: Studies of women's views about antenatal screening and diagnosis were searched for on electronic databases. Studies about pregnancy ultrasound were then identified from this material. Further studies were found by contacting researchers, hand searches, and following up references. The searches were not intentionally limited by date or language. Studies that reported direct data from women about pregnancy ultrasound were then included in a structured review. Studies were not excluded on the basis of methodological quality unless they were impossible to understand. They were read by one author and tabulated. The review then addressed a series of questions in a nonquantitative way. RESULTS: The structured review included 74 primary studies represented by 98 reports. Studies from 18 countries were included, and they employed methods ranging from qualitative interviewing to psychometric testing. The review included studies from the very early period of ultrasound use up to reports of research on contemporary practice. Ultrasound is very attractive to women and families. Women's early concerns about the safety of ultrasound were rarely reported in more recent research. Women often lack information about the purposes for which an ultrasound scan is being done and the technical limitations of the procedure. The strong appeal of diagnostic ultrasound use may contribute to the fact that pregnant women are often unprepared for adverse findings. CONCLUSIONS: Despite the highly varied study designs and contexts for the research included, this review provided useful information about women's views of pregnancy ultrasound. One key finding for clinicians was the need for all staff, women, and partners to be well informed about the specific purposes of ultrasound scans and what they can and cannot achieve.

Antenatal ultrasound screening for fetal abnormalities: a systematic review of studies of cost and cost effectiveness.
OBJECTIVE: To review systematically and critically evidence to derive estimates of costs and cost effectiveness of routine ultrasound screening for fetal abnormalities. DESIGN: A systematic review of the literature using explicit criteria for inclusion of primary research studies, a stated electronic strategy to identify relevant material, and an explanation of why apparently relevant studies have not been included. SETTING: All countries of origin were included. The results of this review are important to obstetricians and to health service managers in the allocation of resources, and others who are considering conducting further research in this area. MAIN OUTCOME MEASURE: Formal economic evaluations and cost studies of routine ultrasound screening. Costs of routine anomaly scans and costs of other procedures carried out as part of antenatal screening by ultrasound. RESULTS: One hundred and ninety-nine studies were identified in total, 24 reaching the final stage of the review. Nine studies were formal economic evaluations and 15 reported costs studies or clinical effectiveness studies with some assessment of cost. The studies were carried out mainly in Europe and in the United States. After quality criteria were applied, data were extracted from six of the economic evaluations and six of the costs studies. One economic evaluation conducted alongside a randomised trial concluded that screening for fetal abnormalities by ultrasound in the second trimester was cost effective, compared with routine antenatal care. The costs of routine scans ranged from Pound Sterling 18 to Pound Sterling 204 and for non-routine ranged from Pound Sterling 32 to Pound Sterling 113. CONCLUSIONS: There is a lack of good quality primary studies of the costs of ultrasound screening in pregnancy. Typically, economic evaluations of ultrasound screening have been based on poor quality evidence of clinical effectiveness. There is a need for more published data on the costs and cost effectiveness of routine ultrasound screening for fetal anomalies, and of the longer term consequences of screening for anomalies.
