 Research uses of predictive scores in neonatology

Group predictions
    1. Comparing study groups for similarity of risk
    2. Auditing the severity of illness in different units
    3. Comparing performance of different units
    4. Determining trends in results over time
    5. Reviewing if infants are treated appropriately for risk (e.g. number of septic screens or ventilation days)
    6. Comparing rates of complications; are some preventable?
Individual predictions
    1. Giving prognostic information
    2. Stratifying infants in trials (to ensure similarity of risk)
    3. Determining individual treatment
