Effectiveness of intensive care of very low birth-weight infants
Insights
Perinatal intensive care effectively reduces newborn mortality and morbidity, as shown by clinical trials. However, its overall population effectiveness and impact on long-term infant handicap rates require further study.
Area of Science:
- Neonatal Medicine
- Public Health
- Health Economics
Background:
- Perinatal and neonatal intensive care are crucial for infant health.
- Evaluating these interventions requires assessing efficacy, effectiveness, and efficiency.
- Existing research provides evidence for efficacy but less so for population-level effectiveness.
Purpose of the Study:
- To evaluate the efficacy, effectiveness, and efficiency of perinatal and neonatal intensive care.
- To synthesize evidence on the impact of intensive care on perinatal/neonatal mortality and morbidity.
- To discuss the economic implications and long-term outcomes of neonatal intensive care.
Main Methods:
- Review of randomized controlled clinical trials for efficacy.
- Analysis of population surveys and hospital-based data for effectiveness.
- Consideration of health outcomes and costs for efficiency assessment.
Main Results:
- Randomized trials demonstrate the efficacy of intensive care in reducing perinatal/neonatal mortality and morbidity.
- Population data suggest declining mortality linked to improved perinatal care, with Level 3 hospitals showing better outcomes for low birth-weight infants.
- While intensive care saves lives, its impact on reducing handicap rates in very low birth-weight infants is uncertain, and costs are high.
Conclusions:
- Perinatal intensive care is efficacious in reducing mortality and morbidity.
- Evidence for population-level effectiveness is suggestive but not experimentally proven.
- Further research is needed on the efficiency and long-term impact on handicap rates, alongside comprehensive economic evaluations.
Abstract:
Perinatal/neonatal intensive care can be evaluated in terms of its efficacy, effectiveness and efficiency. There is good experimental evidence from randomized controlled clinical trials that intensive-care interventions in the perinatal period are efficacious in reducing perinatal/neonatal mortality and fetal/neonatal morbidity. The effectiveness of intensive care programs in large populations has not been tested experimentally. However, population surveys show that perinatal/neonatal mortality is declining and it is likely that this is due in large part to improved perinatal care. Moreover, low birth-weight infants born in Level 3 hospitals have a lower neonatal mortality rate than LBW infants born in hospitals that are less well staffed and equipped. The true size of the reduction in fetal/neonatal mortality that is attributable to perinatal interventions is difficult to estimate from the experience of referral hospitals because of selection bias (both postnatal and prenatal). Thus, the size of the reduction in mortality resulting from the intensive care of VLBW infants is quite striking in hospital-based studies, but more modest in area-based studies. The efficiency of perinatal interventions in reducing death and disability takes into consideration both the health outcomes and the costs attributable to perinatal intensive care. Although neonatal intensive care saves lives, it is doubtful that the rate of handicap in very low birth-weight infants has been much affected. The immediate and long-term costs of neonatal intensive care are high, but a systematic economic evaluation has not yet been published.
