Early comprehensive care of preterm infants-effects on quality of life, childhood development, and healthcare utilization: study protocol for a cohort study linking administrative healthcare data with patient reported primary data.

BACKGROUND: About 9 % of all children in Germany are born preterm. Despite significant improvements of medical care, preterm infants are at a greater risk to develop short and long term health complications. Negative consequences of preterm birth include neurodevelopmental disabilities, behavioral problems or learning disorders. Most data on effects of prematurity are derived from single or multi-center studies and not population-based. Since some of the long term problems of preterm delivery are associated with a disturbed parent-child interaction originating in the neonatal period, several intervention programs became available aiming to strengthen the early parent-child relationship. However, there is insufficient knowledge regarding the psychosocial and socioeconomic impact of these interventions. Prior to introducing them into routine care, those effects have to be rigorously evaluated. The population-based cohort study EcoCare-PIn (Early comprehensive Care of Preterm Infants-effects on quality of life, childhood development, and healthcare utilization) will investigate the following primary research questions: 1) What are the short- and long-term consequences of preterm birth with regard to parental stress, parent-child relationship, childhood development, quality of life and healthcare utilization including costs? 2) Does early family-centered psychosocial care prevent the hypothesized negative consequences of preterm birth on the above mentioned outcomes? METHODS/DESIGN: EcoCare-PIn examines the research questions by means of a linkage of a) pseudonymized administrative individual-level claims data from the German statutory health insurance AOK PLUS on approximately 140,000 children born between 2007 and 2013 in Saxony, and b) primary data collected from the parents/caregivers of all very low birth weight (<1,500 g; n = 1,000) and low birth weight infants (1,500 to 2,500 g; n = 5,500) and a matched sample of infants above 2,500 g birth weight (n = 10,000). DISCUSSION: In Saxony, approximately 50 % of all individuals are insured at the AOK PLUS. The linkage of patient-level administrative and primary data is a novel approach in neonatal research and probably the only way to overcome shortcomings of studies solely relying on one data source. The study results are based on an observation period of up to 8 years and will directly inform perinatal healthcare provision in Saxony and Germany as a whole.

[Health insurance expenses for children in the first five years of life - a cohort-based analysis]. / Ausgaben einer Krankenkasse für Kinder in den ersten fünf Lebensjahren - eine kohortenbasierte Analyse.

INTRODUCTION: The development of paediatrics is characterised by several changes in the past few years, concerning, in particular holistic treatments or preventive check-ups, but also the transfer of treatment from the inpatient to the outpatient sector. There are no reference values for assessing emerging health insurance expenses. The aim of this study was to obtain a frame of reference for the costs of the treatment for neonates, infants, and young children using the example of the expenditures of one health insurance fund. METHODS: The individual health insurance expenditures were analysed for the first five years of life of children insured with the AOK PLUS in Saxony, Germany, in 2005. Costs of hospital treatment, ambulatory care, remedies, tools, medicines and care were included. RESULTS: The costs per insured child and year amounted to approximately 1,277 Euro (N = 11,147), with the highest costs arising in the first two years. 858 Euro were spent annually for an "average" child; 5,691 Euro per year incurred for a child with special medical needs. DISCUSSION: The present cost analysis describes both the height and structure of a health insurance's spendings on children within the first five years of their life in consideration of regional medical care offers. The question of whether this analysis provides valid reference values for other health insurances or other service areas will have to be answered by other analyses.
