Content of data collection at primary hospitalization

Out of the 108 items collected for the MNDS, a group of experts selected those items that reflect the performance of the individual units as opposed to items that cannot be modulated (such as gender, birth defects, socio-economic status, etc.).

The selected items fulfill international standards for the description of mortality and common morbidities in very preterm children. They were then tested for their suitability as quality indicators (QI’s) using the strict criteria of QUALIFY. QUALIFY was developed by the German National Institute for Quality Measurement in Health Care (BQS) as an instrument for the structural appraisal of quality indicators in health care. It offers 3 criteria for the proposed quality indicator’s relevance, 8 for its scientific soundness, and 9 for its feasibility.
