Development of Model of Stage Health Care System for Patients with Bronchopulmonary Dysplasia. Stage I: Determining the Need for Regional Centers for Diagnosis and Treatment

Graphical and polynomial (quantitative) regional model of bronchopulmonary dysplasia (BPD) prevalence, depending on the number of premature children, was substantiated, composed and proposed for use for the first time. This provides an opportunity to perform generalized comparative (at the state level) analysis of BPD diagnosis. BPD incidence rates in groups of prematurely born children with different levels of BW deficiency (BW) were determined by calculating the ratio between the number of children with BPD and the total number of children in specific groups stratified according to the BW level. Advanced (multi-criteria) algorithm of Centers for Diagnosis and Treatment scope of activity quantitation was substantiated and developed for the first time based on regional frequency of premature children and the degree of their body weight deficiency. Inverse verification of this algorithm was conducted and rather high accuracy for practical use by the health professionals was proved. Nomogram (graphical and tabular versions) for operating planning of the expected absolute number of patients with BPD depending on the number of regional premature children was newly developed and substantiated according to the results of the research.
