Economics of prematurity in the era of managed care

Parenteral nutrition and oxidant stress in the newborn: A narrative review

There is strong evidence that oxidant molecules from various sources contaminate solutions of parenteral nutrition following interactions between the mixture of nutrients and some of the environmental conditions encountered in clinical practice. The continuous infusion of these organic and nonorganic peroxides provided us with a unique opportunity to study in cells, in vascular and animal models, the mechanisms involved in the deleterious reactions of oxidation in premature infants. Potential clinical impacts of peroxides infused with TPN include: a redox imbalance, vasoactive responses, thrombosis of intravenous catheters, TPN-related hepatobiliary complications, bronchopulmonary dysplasia and mortality. This is a narrative review of published data.

Economic assessment of neonatal intensive care

Most of the studies on the costing of neonatal intensive care has concentrated on the costs associated with preterm infants which takes up more than half of neonatal intensive care unit (NICU) costs. The focus has been on determining the cost-effectiveness of extreme preterm infants and those at threshold of viability. While the costs of care have an inverse relationship with gestational age (GA) and the lifetime medical costs of the extreme preterm can be as high as $450,000, the total NICU expenditure are skewed towards the care of moderate and late preterm infants who form the main bulk of patients. Neonatal intensive care, has been found to be very cost-effective at $1,000 per term infant per QALY and $9,100 for extreme preterm survivor per QALY. For low and LMIC, where NICU resources are limited, the costs of NICU care is lower largely due to a patient profile of more term and preterm of greater GAs and correspondingly less intensity of care. Public health measures, neonatal resuscitation training, empowerment of nurses to do resuscitation, increasing the accessibility to essential newborn care are recommended cheaper cost-effective measures to reduce neonatal mortality in countries with high neonatal mortality rate, whilst upgraded neonatal intensive care services are needed to further reduce neonatal mortality rate once below 15 per 1,000 livebirths. Economic evaluation of neonatal intensive care should also include post discharge costs which mainly fall on the health, social and educational sectors. Strategies to reduce neonatal intensive care costs could include more widespread implementation of cost-effective methods of improving neonatal outcome and reducing neonatal morbidities, including access to antenatal care, perinatal interventions to delay preterm delivery wherever feasible, improving maternal health status and practising cost saving and effective neonatal intensive care treatment.

Costs and cost-effectiveness of periviable care

With increasing concerns regarding rapidly expanding healthcare costs, cost-effectiveness analysis allows assessment of whether marginal gains from new technology are worth the increased costs. Particular methodologic issues related to cost and cost-effectiveness analysis in the area of neonatal and periviable care include how costs are estimated, such as the use of charges and whether long-term costs are included; the challenges of measuring utilities; and whether to use a maternal, neonatal, or dual perspective in such analyses. A number of studies over the past three decades have examined the costs and the cost-effectiveness of neonatal and periviable care. Broadly, while neonatal care is costly, it is also cost effective as it produces both life-years and quality-adjusted life-years (QALYs). However, as the gestational age of the neonate decreases, the costs increase and the cost-effectiveness threshold is harder to achieve. In the periviable range of gestational age (22-24 weeks of gestation), whether the care is cost effective is questionable and is dependent on the perspective. Understanding the methodology and salient issues of cost-effectiveness analysis is critical for researchers, editors, and clinicians to accurately interpret results of the growing body of cost-effectiveness studies related to the care of periviable pregnancies and neonates.

Economic analysis of the costs associated with prematurity from a literature review

OBJECTIVES

To analyse published cost-of-illness studies that had assessed the cost of prematurity according to gestational age at birth.

METHODS

A review of the literature was carried out in March 2011 using the following databases: Medline, ScienceDirect, The Cochrane Library, Econlit and Business Source Premier, and a French Public-Health database. Key-word sequences related to 'prematurity' and 'costs' were considered. Studies that assessed costs according to the gestational age (GA) at the premature birth (<37 weeks of gestation) in industrialized countries and during the last two decades were included. Variations in the reported costs were analysed using a check-list, which allowed the studies to be described according to several methodological and contextual criteria.

RESULTS

A total of 18 studies published since 1990 were included. According to these studies, costs were assessed for different follow-up periods (short, medium or long-term), and for different degrees of prematurity (extreme, early, moderate and late). Results showed that whatever the follow-up period, costs correlated inversely with GA. They also showed considerable variability in costs within the same GA group. Differences between studies could be explained by the choices made, concerning i/the study populations, ii/contextual information, iii/and various economic criteria. Despite these variations, a global trend of costs was estimated in the short-term period using mean costs from four American studies that presented similar methodologies. Costs stand at over US$ 100,000 for extreme prematurity, between US$ 40,000 and US$ 100,000 for early prematurity, between US$ 10,000 and US$ 30,000 for moderate prematurity and below US$ 4500 for late prematurity.

CONCLUSION

This review underlined not only the clear inverse relationship between costs and GA at birth, but also the difficulty to transfer the results to the French context. It suggests that studies specific to the French health system need to be carried out.

The prediction and cost of futility in the NICU

AIM

To quantify the cost and prediction of futile care in the Neonatal Intensive Care Unit (NICU).

METHODS

We observed 1813 infants on 100,000 NICU bed days between 1999 and 2008 at the University of Chicago. We determined costs and assessed predictions of futility for each day the infant required mechanical ventilation.

RESULTS

Only 6% of NICU expenses were spent on nonsurvivors, and in this sense, they were futile. If only money spent after predictions of death is considered, futile expenses fell to 4.5%. NICU care was preferentially directed to survivors for even the smallest infants, at the highest risk to die. Over 75% of ventilated NICU infants were correctly predicted to survive on every day of ventilation by every caretaker. However, predictions of 'die before discharge' were wrong more than one time in three. Attendings and neonatology fellows tended to be optimistic, while nurses and neonatal nurse practitioners tended to be pessimistic.

CONCLUSIONS

Criticisms of the expense of NICU care find little support in these data. Rather, NICU care is remarkably well targeted to patients who will survive, particularly when contrasted with care in adult ICUs. We continue to search for better prognostic tools for individual infants.

Clinical benefits, costs, and cost-effectiveness of neonatal intensive care in Mexico

BACKGROUND

Neonatal intensive care improves survival, but is associated with high costs and disability amongst survivors. Recent health reform in Mexico launched a new subsidized insurance program, necessitating informed choices on the different interventions that might be covered by the program, including neonatal intensive care. The purpose of this study was to estimate the clinical outcomes, costs, and cost-effectiveness of neonatal intensive care in Mexico.

METHODS AND FINDINGS

A cost-effectiveness analysis was conducted using a decision analytic model of health and economic outcomes following preterm birth. Model parameters governing health outcomes were estimated from Mexican vital registration and hospital discharge databases, supplemented with meta-analyses and systematic reviews from the published literature. Costs were estimated on the basis of data provided by the Ministry of Health in Mexico and World Health Organization price lists, supplemented with published studies from other countries as needed. The model estimated changes in clinical outcomes, life expectancy, disability-free life expectancy, lifetime costs, disability-adjusted life years (DALYs), and incremental cost-effectiveness ratios (ICERs) for neonatal intensive care compared to no intensive care. Uncertainty around the results was characterized using one-way sensitivity analyses and a multivariate probabilistic sensitivity analysis. In the base-case analysis, neonatal intensive care for infants born at 24-26, 27-29, and 30-33 weeks gestational age prolonged life expectancy by 28, 43, and 34 years and averted 9, 15, and 12 DALYs, at incremental costs per infant of US$11,400, US$9,500, and US$3,000, respectively, compared to an alternative of no intensive care. The ICERs of neonatal intensive care at 24-26, 27-29, and 30-33 weeks were US$1,200, US$650, and US$240, per DALY averted, respectively. The findings were robust to variation in parameter values over wide ranges in sensitivity analyses.

CONCLUSIONS

Incremental cost-effectiveness ratios for neonatal intensive care imply very high value for money on the basis of conventional benchmarks for cost-effectiveness analysis. Please see later in the article for the Editors' Summary.

Outcome and hospital cost for infants weighing less than 500 grams: a tertiary centre experience in Taiwan

AIM

To determine the outcome and hospital cost for infants weighing < or =500 g at a tertiary centre in Taiwan.

METHODS

We retrospectively reviewed the medical records of infants who were born alive with birthweight < or =500 g at the National Taiwan University Hospital from 1997 to 2004. Their outcome and hospital cost were analysed.

RESULTS

A total of 168 infants were included for analysis that 146 of them died after compassionate care in the delivery room and 22 received postnatal resuscitation. The infants who received resuscitation were more likely to have higher birthweights, older gestational ages and multiple births compared with those who received compassionate care. After resuscitation, five of the infants died and 17 were admitted to neonatal intensive care unit (NICU) for further management. Subsequently, 12 infants died and five infants survived to discharge. Two infants were discharged against advice and died within days. After exclusion of those receiving compassionate care, the NICU survival rate was 22.7% and the long-term survival rate was 13.6%. The most common early morbidities were respiratory distress syndrome, intraventricular haemorrhage and patent ductus arteriosus, whereas the late morbidities included cholestatic jaundice, retinopathy of prematurity and chronic lung disease. The average total hospital costs for the NICU survivors with birthweight < or =500 g was US $42,411 and the average hospital cost per day was US $350.

CONCLUSION

Exclusive compassionate care was given to the majority of the infants weighing < or =500 g in Taiwan. The survival rate remained low in these marginally viable infants.

Moderately premature infants at Kaiser Permanente Medical Care Program in California are discharged home earlier than their peers in Massachusetts and the United Kingdom

OBJECTIVE

To compare gestational age at discharge between infants born at 30-34(+6) weeks gestational age who were admitted to neonatal intensive care units (NICUs) in California, Massachusetts, and the United Kingdom.

DESIGN

Prospective observational cohort study.

SETTING

Fifty four United Kingdom, five California, and five Massachusetts NICUs.

SUBJECTS

A total of 4359 infants who survived to discharge home after admission to an NICU.

MAIN OUTCOME MEASURES

Gestational age at discharge home.

RESULTS

The mean (SD) postmenstrual age at discharge of the infants in California, Massachusetts, and the United Kingdom were 35.9 (1.3), 36.3 (1.3), and 36.3 (1.9) weeks respectively (p = 0.001). Compared with the United Kingdom, adjusted discharge of infants occurred 3.9 (95% confidence interval (CI) 1.4 to 6.5) days earlier in California, and 0.9 (95% CI -1.2 to 3.0) days earlier in Massachusetts.

CONCLUSIONS

Infants of 30-34(+6) weeks gestation at birth admitted and cared for in hospitals in California have a shorter length of stay than those in the United Kingdom. Certain characteristics of the integrated healthcare approach pursued by the health maintenance organisation of the NICUs in California may foster earlier discharge. The California system may provide opportunities for identifying practices for reducing the length of stay of moderately premature infants.

Evaluation of neonatal intensive care for extremely-low-birth-weight infants

Neonatal intensive care for extremely-low-birth-weight (ELBW, 500-999 g) infants must be evaluated to determine that it is effective, efficient, and available to those who need it. From the late 1970s until the late 1990s in the state of Victoria, Australia, neonatal intensive care has been increasingly effective, with large increases in the long-term survival rate from 25% in 1979-1980 to 73% in 1997, and in the quality-adjusted survival rate from 19% to 59% over the same time. Its efficiency has been relatively high and stable over time, comparing favourably with many other health-care programmes. It is increasingly available, with fewer than 10% of ELBW infants born outside level III perinatal centres in the latest era, and proportionally more ELBW infants being offered intensive care over time. Neonatal intensive care should be re-evaluated at intervals in the future to ensure that its effectiveness, efficiency and availability are maintained.

The cost of prematurity: hospital charges at birth and frequency of rehospitalizations and acute care visits over the first year of life: a comparison by gestational age and birth weight

The proportion of preterm and low-birth-weight infants has been growing steadily for two decades. Most of the more than US 10 billion dollars spent on neonatal care in the United States in 2003 was spent on the 12.3% of infants who were born preterm. Research has shown higher initial hospital costs and a higher rate of acute care visits and rehospitalization for preterm and low-birth-weight infants, but only a limited number of studies of the cost of prematurity that follow infants through the first year of life have been conducted. This study is a secondary analysis of data on a subset of infants drawn from a randomized clinical trial that examined health outcomes and health care costs in women with high-risk pregnancies and their infants. For the current study, a sample of 84 singleton infants was chosen. Forty-three infants (51%) were full term (37 weeks' gestation or more) and 41 (49%) were born preterm (less than 37 weeks' gestation). Fifty-five infants (65.5%) were born at normal birth weights (2,500 g or greater), 24 (28.5%) were born at low birth weights (1,501 to 2,499 g), and five (6%) were born at very low birth weights (less than 1,500 g). Data on the initial hospital charges and the rates of rehospitalization and acute care visits in the first year of life in relation to gestational age and birth weight were collected. The results clearly demonstrated that the charges for initial hospitalizations increased as birth weights and gestational ages decreased. Low-birth-weight infants were less likely to have unscheduled acute care visits than normal-birth-weight infants. Interventions to improve prenatal care targeted to women at high risk for delivering preterm or low-birth-weight infants would reduce health care costs and improve health outcomes of infants as well.

Using computer vision to help the determination of the gestational age of newborns

RATIONALE AND OBJECTIVES

This report presents a computational approach to help the gestational age determination of newborns. Gestational age knowledge is fundamental to guide postnatal treatment and increase survival chances of newborns. However, current methods are invasive and do not generate precise results, mainly because they were developed based on nonpremature populations.

MATERIALS AND METHODS

We developed an original and noninvasive method to help determination of gestational age based on information supplied by plantar surface images. These images present many details and patterns, but, to date, have not received attention from the image-processing community. We provide a computational tool with suitable facilities to allow the image analysis, either automatically or user driven. This image-processing tool is presented here.

RESULTS

The image-processing tool was developed on a user-driven basis. However, as a quantitative experiment, 186 images were processed without user intervention to observe tool behavior in performing different tasks. Although preliminary, experimental results confirm the relationship between plantar surface features and gestational age.

CONCLUSION

A prototype of the FootScanAge System is being used and evaluated by experts in neonatology. By means of digital processing of plantar surface images, some characteristics may be shown. Some hypotheses regarding the method have already been confirmed. Also, we show that some well-known image-processing techniques, if appropriately adapted, lead to suitable results when applied to plantar surface images.

Análise situacional do atendimento ambulatorial prestado a recém-nascidos egressos das unidades de terapia intensiva neonatais no Estado do Rio de Janeiro

A diminuição da mortalidade neonatal contribui para o aumento de crianças que necessitam de maior atenção em relação a morbidades clínicas e à evolução do desenvolvimento neuropsicomotor. O objetivo deste estudo foi discutir a situação da assistência às crianças egressas das Unidades de Terapia Intensiva Neonatais (UTIN) em cinco unidades em diferentes regiões do Estado do Rio de Janeiro; em nenhuma havia informações sobre o perfil dos egressos da UTIN. Evidenciou-se restrição ao acesso e baixa estruturação da rede em relação à assistência prestada a esses bebês. Não há uniformidade no atendimento prestado, e ambulatórios específicos para essa população concentram-se na cidade do Rio de Janeiro. Constatou-se deficiência de profissionais nas áreas de reabilitação - fisioterapia motora, terapia ocupacional, fonoaudiologia e psicologia -, e de especialistas para atendimento oftalmológico adequado e para a criança portadora de deficiência auditiva. Os autores discutem possíveis explicações para essa situação, propondo a organização de um sistema de atendimento em graus de complexidade para poder viabilizar o acesso das crianças de risco a um atendimento diferenciado, importante para detecção precoce de anormalidades do desenvolvimento.

Health-related quality of life as a predictor of pediatric healthcare costs: a two-year prospective cohort analysis

Background

The objective of this study was to test the primary hypothesis that parent proxy-report of pediatric health-related quality of life (HRQL) would prospectively predict pediatric healthcare costs over a two-year period. The exploratory hypothesis tested anticipated that a relatively small group of children would account for a disproportionately large percent of healthcare costs.

Methods

317 children (157 girls) ages 2 to 18 years, members of a managed care health plan with prospective payment participated in a two-year prospective longitudinal study. At Time 1, parents reported child HRQL using the Pediatric Quality of Life Inventory™ (PedsQL™ 4.0) Generic Core Scales, and chronic health condition status. Costs, based on health plan utilization claims and encounters, were derived for 6, 12, and 24 months.

Results

In multiple linear regression equations, Time 1 parent proxy-reported HRQL prospectively accounted for significant variance in healthcare costs at 6, 12, and 24 months. Adjusted regression models that included both HRQL scores and chronic health condition status accounted for 10.1%, 14.4%, and 21.2% of the variance in healthcare costs at 6, 12, and 24 months. Parent proxy-reported HRQL and chronic health condition status together defined a 'high risk' group, constituting 8.7% of the sample and accounting for 37.4%, 59.2%, and 62% of healthcare costs at 6, 12, and 24 months. The high risk group's per member per month healthcare costs were, on average, 12 times that of other enrollees' at 24 months.

Conclusions

While these findings should be further tested in a larger sample, our data suggest that parent proxy-reported HRQL can be used to prospectively predict healthcare costs. When combined with chronic health condition status, parent proxy-reported HRQL can identify an at risk group of children as candidates for proactive care coordination.

Physical growth and neurodevelopmental outcome of nonhandicapped low-risk children born preterm

BACKGROUND

Outcome studies on the effects of prematurity are increasingly restricted to extremely immature infants with birth weight below 1000 g or gestational age below 26 weeks. In contrast, studies comprising low-risk preterm infants are rare.

AIM

To examine growth and neurodevelopmental outcome, 70 low-risk low birth weight (LBW) children without neurological impairment were followed from birth to 7 years of age. At 7 years of age, LBW children were compared to a matched control group born at term.

METHODS

Postnatal growth was measured at 20 months in the LBW group and at 7 years in LBW and control children. At 20 months, the LBW group was assessed with the Griffiths Scales. At 7 years, LBW and control children were assessed with a neuropsychological test battery comprising tests for language, visual-perceptual, visual-motor, fine and gross motor abilities.

RESULTS

At 7 years of age, the frequency of children with low (3rd-9th percentile) or subnormal (<3rd percentile) growth parameters was increased in the LBW group. The Mean Griffiths Developmental Quotient (DQ) of the preterm group was normal (102.3+/-8.4), and there were only two results below DQ 85. There was no difference between 49 children appropriate for gestational age and 21 small for gestational age (SGA) children. At 7 years of age, reduced mean test results in the range of -0.5 SDS were observed for language and visual-motor abilities in the preterm group. This was due to an increased frequency of LBW children with moderately (SDS -1.0 to -2.0 SDS) subnormal test results. Even for the slightly LBW group (2000 to 2499 g), poorer language abilities were confirmed.

CONCLUSION

All LBW infants, including low-risk populations, should be included in a follow-up program in order to detect deficits early in life and begin treatment before school entry.

The prevalence of preterm deliveries in Berlin has not changed over 7 years: the impact of multiple births

The problem of preterm deliveries has worsened in developed countries over the past decade. To evaluate whether multiple deliveries had an impact on this development, we analyzed the data of the Berlin Perinatal Survey from 1993-1999 for 206,308 deliveries. The prevalence of preterm deliveries was fairly constant during this period, and the proportion of preterm deliveries in the case of multiples remained constant. But the prevalence of preterm neonates increased significantly in Berlin due to an increased prevalence of multiple births. There was a significant increase of mothers aged over 30, of German nationality, and with preceding infertility treatment, while the prevalence rates of nearly all other risk factors for prematurity decreased over time. The risk of infertility treatments resulting in multiple deliveries increased in these years. On average, infertility treatment led to an about 10 times higher risk of producing multiples than singletons OR (95% CI) of 9.6 (8.6-10.6).

Cost-effectiveness of inhaled nitric oxide for the management of persistent pulmonary hypertension of the newborn

OBJECTIVE

Inhaled nitric oxide (iNO) is a selective pulmonary vasodilator that has become part of the standard management for persistent pulmonary hypertension of the newborn (PPHN). This treatment modality, like many in neonatology, has not been well studied using quantitative economic techniques. The objective of this study was to evaluate the economic impact of adding iNO to the treatment protocol of PPHN for term infants from birth to the time of discharge from their initial hospitalization.

METHODS

We used decision analysis modeling from a societal perspective to obtain an incremental cost-effectiveness ratio. Outcome probabilities were taken from the medical literature and a cohort of 123 infants who were treated with PPHN at The Children's Hospital of Philadelphia between 1991 and 2002. Costs were estimated from daily resources used by these infants in 2001 dollars. Survival and quality-adjusted life years were used as effectiveness measures. One-way, threshold, and probabilistic sensitivity analyses were performed to assess the robustness of the base-case estimate.

RESULTS

The addition of iNO to the treatment regimen of PPHN increased the cost of treating an infant by an average of 1141 dollars, primarily from an increased number of mechanical ventilation days. Use of iNO led to 3.4% more lives saved and a 6% increase in the average utility gained per infant. The incremental cost-effectiveness ratio was 33,234 dollars per life saved and 19,022 dollars per quality-adjusted life year gained. The model was robust to changes in outcome probabilities, cost, and utility variables. Only 3.6% of the trials using probabilistic sensitivity analysis found iNO to be more expensive with a worse outcome than conventional therapy alone, whereas 35.7% of the trials found iNO to be cheaper and more effective than conventional treatment alone.

CONCLUSIONS

iNO is cost-effective but not cost-saving in treating infants with PPHN from a societal perspective. There are critical time points during an infant's hospitalization that could improve the efficiency and consequently the cost of care for this patient population.

Clinical outcomes of near-term infants

OBJECTIVE

To test the hypothesis that near-term infants have more medical problems after birth than full-term infants and that hospital stays might be prolonged and costs increased.

METHODS

Electronic medical record database sorting was conducted of 7474 neonatal records and subset analyses of near-term (n = 120) and full-term (n = 125) neonatal records. Cost information was accessed. Length of hospital stay, Apgar scores, clinical diagnoses (temperature instability, jaundice, hypoglycemia, suspicion of sepsis, apnea and bradycardia, respiratory distress), treatment with an intravenous infusion, delay in discharge to home, and hospital costs were assessed.

RESULTS

Data from 90 near-term and 95 full-term infants were analyzed. Median length of stay was similar for near-term and full-term infants, but wide variations in hospital stay were documented for near-term infants after both vaginal and cesarean deliveries. Near-term and full-term infants had comparable 1- and 5-minute Apgar scores. Nearly all clinical outcomes analyzed differed significantly between near-term and full-term neonates: temperature instability, hypoglycemia, respiratory distress, and jaundice. Near-term infants were evaluated for possible sepsis more frequently than full-term infants (36.7% vs 12.6%; odds ratio: 3.97) and more often received intravenous infusions. Cost analysis revealed a relative increase in total costs for near-term infants of 2.93 (mean) and 1.39 (median), resulting in a cost difference of 2630 dollars (mean) and 429 dollars (median) per near-term infant.

CONCLUSIONS

Near-term infants had significantly more medical problems and increased hospital costs compared with contemporaneous full-term infants. Near-term infants may represent an unrecognized at-risk neonatal population.

Evaluation of neonatal intensive care for extremely low birth weight infants in Victoria over two decades: II. Efficiency

CONTEXT

Although the increasing effectiveness of neonatal programs for extremely low birth weight (ELBW, birth weight <1000 g) infants has been established from cohort studies, there is a paucity of data on the relationship between the costs and the consequences of neonatal intensive care.

OBJECTIVE

To determine the changes in the efficiency of neonatal intensive care for ELBW infants in Victoria, Australia over 2 decades.

DESIGN

Economic evaluation (cost-effectiveness and cost-utility analyses) in a population-based cohort study of consecutive ELBW infants born during 4 distinct eras (1979-1980, 1985-1987, 1991-1992, and 1997) followed to at least 2 years of age.

SETTING

The state of Victoria.

PATIENTS

All ELBW live births of birth weight 500 to 999 g in the state in the calendar years indicated (1979-1980: n = 351; 1985-1987: n = 560; 1991-1992: n = 429; 1997: n = 233).

MAIN OUTCOME MEASURES

Costs were assessed primarily by the consumption of hospital resources. The consequences included survival and quality-adjusted survival rates at 2 years of age.

RESULTS

The cost-effectiveness ratios (expressed in Australian dollars for 1997) were similar between successive eras at 5270 dollars, 3130 dollars, and 4050 dollars per life-year gained, respectively. The cost-utility ratios were similar between successive eras at 5270 dollars, 3690 dollars, and 5850 dollars per quality-adjusted life-year gained, respectively, and were similar to the cost-effectiveness ratios. The cost-effectiveness and cost-utility ratios were generally higher in lower birth-weight subgroups, but there were consistent gains in efficiency over time in infants of lower birth weight.

CONCLUSIONS

As there have been large increases in effectiveness from the late 1970s to the late 1990s, the efficiency of neonatal intensive care for ELBW infants in Victoria has remained relatively stable.

Evidence-based ethics and the care and outcome of extremely premature infants

The care of extremely premature infants involves a number of complex clinical and ethical issues. The ethical and scientific quality of decisions made in the care of these infants has profound long-term consequences for these infants and their families. In circumstances when it is unclear whether intensive care should be initiated or continued, evidence-based ethics provides an approach to facilitate treatment decisions that over time will be progressively better informed, better justified, and more broadly acceptable to parents, caregivers, and the general public.

Characterization of neonatal personnel time inputs and prediction from clinical variables--a time and motion study

OBJECTIVE

To characterize and predict personnel time inputs to neonatal intensive care using infant characteristics from chart review.

STUDY DESIGN

For 12 hours each day, observers timed all direct care, charting, discussions, and procedures for 154 infants. Time inputs were correlated with 40 infant characteristics and resource markers, as well as the Score for Neonatal Acute Physiology (SNAP) for that day of care.

RESULTS

Nurses accounted for 76%, respiratory therapists 8%, fellows 5%, nurse practitioners 7% and attendings 5% of total time invested in patient care. Nurses and respiratory therapists spent proportionately more time in direct patient care. In regression models, a limited number of variables explained 36% of the variance in time input per patient for respiratory therapists (p<0.0001), 42% for nurses (p<0.0001), and 23% for physicians and nurse practitioners (p<0.0001).

CONCLUSIONS

Total labor inputs can be accurately predicted through the use of a limited number of clinical characteristics. This technique should be routinely employed to improve the accuracy of economic evaluations. Nursing accounts for the majority of time invested in neonatal care. Improved efficiency in neonatology is thus most likely to be generated by interventions that reduce direct nursing time.

Ethical aspects of cardiopulmonary resuscitation in premature neonates: where do we stand?

Advances in diagnosis, techniques, therapeutic interventions, organisation of perinatal care, and socio-economic factors have all contributed to the survival after resuscitation and intensive care of neonates with extremely low birth weight and gestational age. While morbidity during the first years of life in those infants does not increase, at school age multiple dysfunctions may become apparent. What are the limits of intensive care for the newborn? Is it right to use extreme technical and economic measures for neonates with a borderline chance of survival? What is justifiable for the neonate, the family, the society and how does legislation interfere in a decision process which involves starting, stopping or continuing intensive care? A short historical overview for the care of the newborn is given, followed by the outcome after resuscitation and treatment of the very low birth weight infant. Published management strategies and recommendations are discussed.

A critical review of cost reduction in neonatal intensive care. I. The structure of costs

Neonatal intensive care is expensive. In the current era of intense cost containment in hospital care, neonatologists and hospital administrators are under intense pressure to find strategies for cost reduction for neonatal services. Few neonatal clinicians are trained in economics, management, or accounting, and few hospital administrators are familiar with neonatal intensive care. In this review, we describe the structure and sources of hospital costs and the accounting systems needed to isolate and measure such costs. We discuss where efficiencies might be found and consider specific issues in capitated settings such as health maintenance organizations in the United States, the Canadian health care system and the National Health System in the United Kingdom.
