[Perinatal Networks: Ensuring Regional Care of Pregnant Woman and Newborns]. / Perinatologische Kompetenznetzwerke: Die Versorgung von Schwangeren und Neugeborenen in einer Region.

Health care of pregnant women and their newborns is facing major challenges due to the decline in birth rate and shortage of specialists. In the current discussion about future concepts, the centralization associated with minimum quantities and the necessary safeguarding of care in the area are often construed as conflicting goals. Instead, concepts are needed to guarantee that pregnant women and their children will continue to receive care close to home. The example of the saxony center for feto/neonatal health is used to show how partners in a region can jointly ensure care during pregnancy, birth and the neonatal period on a supra-local and cross-hospital basis. The close cooperation of maximum care providers with regional partners enables comprehensive health care. At the same time, this cooperation enables hospitals to remain attractive employers in structurally weak regions and to provide comprehensive care for young families in need of medical services related to pregnancy and birth through good family and social integration close to home and work. The overriding goals of the saxony center for feto/neonatal health are optimal, guideline-based, interdisciplinary and intersectoral care of pregnant women and premature or sick newborns in the region.

[Association between Socioeconomic Status and Developmental Status: Data Linkage of Results of the Daycare and School Entry Health Examinations of a Saxon Birth Cohort Study]. / Zusammenhang zwischen sozioökonomischem Status und Entwicklungsstand ­ Datenlinkage von Ergebnissen der Kita- und Schulaufnahmeuntersuchung mit einer sächsischen Geburtskohortenstudie.

BACKGROUND: Child development is determined by both biological (e. g. gender, natal maturity) and psychosocial (e. g. socioeconomic status, daycare) factors. OBJECTIVES: To examine how familial socioeconomic status (SES) as well as biological and other psychosocial factors are associated with the state of development of 4- and 6-year-old children. METHODS: Data linkage of primary data from a birth cohort study and routine data from the Saxon public health departments on children born between 2007 and 2008, who underwent both daycare health examination and school entry health examination (N=615), was used to examine speech and motor skills, both fine and gross, for associations with psychosocial and biological factors. Potential associations were tested for significance and shown as odds ratios by using binary logistic regression. RESULTS: There were no noticeable problems in the development of the majority of Saxon children until school entry. Nevertheless, language seems to be a sensitive area of development, since 37% of the children showed problems at both time-points. Furthermore boys, preterm infants and children from a lower socio-economic class were more often affected by developmental delays, with preterm infants with low SES being at very high risk. Furthermore, the point of time of entering daycare seems to be of relevance for child development. CONCLUSIONS: The results are in line with national and international findings. An important new finding is the significantly increased likelihood of having developmental problems when biological and psychosocial risk factors coincide. However, longitudinal analyses are required to study developmental courses and to evaluate measures initiated to combat these issues.

Individual-Level Linkage of Primary and Secondary Data from Three Sources for Comprehensive Analyses of Low Birthweight Effects.

AIM OF THE STUDY: The linkage of primary and secondary data is becoming an increasingly popular approach in healthcare research, but involves some challenges for all involved parties, for example due to data protection requirements. The aim of this article is to systematically outline the methods used and experiences made during a cohort study in the field of pediatric health care research (EcoCare-PIn) that involved access to and linkage of three different data sources. Particular focus is placed on the necessary regulatory measures with regard to data access and data linkage as well as on data validation to ensure a correct linkage. METHODS: While complying with all relevant data protection requirements, the study realized an individual-level linkage of a) pseudonymized administrative health insurance data from a statutory health insurance on Saxon children born between 2007 and 2013, b) primary data collected via postal questionnaires from parents/caregivers and c) medical data from kindergarten- and school-entry-examinations of Saxon health authorities. The fundamental principle of the concept of data linkage was to strictly separate the sites of data collection and data analysis, which was realized through the involvement of a trust center. RESULTS: Challenges especially pertained to the extensive regulatory pre-requirements for data access as well as to data protection requirements while performing the study. Technical aspects and data validation also required a considerable share of attention and resources. A number of validation routines were applied to avoid incorrect data linkage and to ensure the high quality of the final dataset. Data validation included both plausibility checks within the primary data and consistency checks of information given in primary and secondary data. CONCLUSION: The linkage of primary and secondary data on the individual level offers great opportunities for using the strengths of different data sources synergistically and overcoming some of their limitations. Statutory health insurance data and medical data from kindergarten- and school-entry-examinations of Saxon health authorities are examples of already existing data sources that can complement cost-consuming primary data collections by valuable data sets and open up opportunities for longitudinal analysis.

[Intrauterine Growth Restriction: Transsectoral, Interdisciplinary and Multiprofessional Care for Pregnant Women and Newborns in a Feto-neonatal Pathway: A Project of the Innovationsfonds]. / Intrauterine Wachstumsrestriktion: Transsektorale, interdisziplinäre und multiprofessionelle Betreuung von Schwangeren und Neugeborenen im Feto-Neonat-Pfad: Ein Projekt des Innovationsfonds.

Intrauterine growth restriction (IUGR) is present in fetuses that do not achieve their full in-utero growth potential. IUGR needs to be discriminated from small for gestational age (SGA) because IUGR newborns in particular experience long-term side effects from their small growth. IUGR fetuses have a significantly increased risk of prematurity and a distinct risk profile compared to adequate-for-gestational-age preterm newborns. Complications of prematurity are more frequent, including bronchopulmonary dysplasia, intraventricular hemorrhage, and meconium ileus. IUGR newborns are at risk of long-term health issues like cerebral palsy, impaired lung function, and delayed speech development. Interdisciplinary and interprofessional care of IUGR pregnancies in the context of a standardized health care research project is feasible: Pregnant women at risk are identified, early therapy with acetylsalicylic acid is started as indicated, risk-adapted care at level III centers is organized including psychosocial interventions and neonatal consultations. Postnatally, integrated neonatal care focusing on parent-child interaction and optimized nutrition is a hallmark. Afterwards, in-depth pediatric follow-up visits with local pediatricians help to identify growth and neurodevelopment problems early. The effects, acceptance. and cost efficiency of this approach are evaluated prospectively as part of an Innovationsfonds project.

Impact of birthweight on health-care utilization during early childhood - a birth cohort study.

BACKGROUND: Comprehensive data are needed to evaluate the burden of low birthweight. Analysis of routine data on health-care utilization during early childhood were used to test the hypothesis that infants with low birthweight have (i) increased inpatient health-care utilization, (ii) higher hospital costs and (iii) different morbidity pattern in early childhood when compared with normal birthweight infants. METHODS: Children born between 2007 and 2013 that were insured at birth with the statutory health insurance AOK PLUS were included (N = 118,166, equaling 49% of the Saxon newborns) and classified into very low (< 1500 g, VLBW), low (1500-2499 g, LBW) birthweight and reference group (> 2500 g). Outcomes were: inpatient health-care utilization quantified by number and length of hospital stays; costs of hospitalizations including medication; reasons of hospitalizations for each year of life (YOL). RESULTS: 72, 38 and 22% of VLBW-, LBW- and reference group were hospitalized after perinatal period within the first YOL with a more than 5-fold increased risk in VLBW to be hospitalized for hemangioma, convulsions, hydrocephalus, hernia and respiratory problems. Median (IQR) cumulative cost of inpatient care during the first four YOLs was 2953 (1213-7885), 1331 (0-3451) and 0 (0-2062) Euro for respective groups. Inpatient early childhood health-care utilization (after first YOL) was higher in VLBW compared to healthy, normal birth weight infants (RR 3.92 [95%-CI 3.63, 4.23]), residents of rural areas (RR 1.37 [95%-CI 1.35, 1.40]) and in boys (RR 1.31 [95%-CI 1.29, 1.33]). CONCLUSION: This large population-based birth-cohort study indicates a high clinical and economic burden of low birthweight which is not restricted to the first year of life.

Methamphetamine Consumption during Pregnancy - Effects on Child Health.

Methamphetamine abuse during pregnancy represents an emerging health care problem. The consequences are not only of relevance to the pregnant women, but also their unborn child. It is associated with an increased risk of preeclampsia and hypertension, fetal demise, preterm delivery, and intrauterine growth restriction. The deleterious effects of prenatal methamphetamine exposure on the developing fetal brain may lead to long-term neuro-developmental and behavioral problems.Given the current evidence, abuse of methamphetamine during pregnancy must be of utmost concern to health care professionals and to policy-makers. As it has been described for neonatal abstinence syndrome, a multi-professional team is required to improve care of affected women and families. A multi-disciplinary approach is needed, including good prenatal care of pregnant women, perinatal care by specialized obstetricians and neonatologists, and psychiatric treatment by an addiction specialist. Furthermore, families should be integrated into appropriate social support networks.For the development of a structured support program for pregnant women with methamphetamine consumption, methamphetamine use disorder should be considered as a disease that requires medical treatment as well as psychological and social support. The pregnancy should be considered as a window of opportunity to provide the required help.

[Increasing Consumption of Crystal Meth in Saxony and its Risks for Mother and Child - Experiences at a Level I Perinatal Center from a Pediatric Viewpoint]. / Steigender Konsum von Crystal Meth in Sachsen und dessen Risiken für Mutter und Kind ­ Erfahrungen an einem Perinatalzentrum Level I aus pädiatrischer Sicht.

Over the past several years, the number of first-time users of methamphetamine considerably increased within the Free State of Saxony. This number also, and especially, includes women of child-bearing age and young mothers. A supportive intervention aimed at reducing the effects of drug abuse should begin in a timely way - during pregnancy at latest, but better before it. To develop an optimal care protocol for both the mother and her child, more knowledge regarding the personal conditions of the women as well as the specific features of later child development after prenatal methamphetamine exposure (PME) is vital. In this study, the data of 129 women and their newborns with PME who were admitted to a Level-1 perinatal center between 2007 and 2015 were analyzed. At delivery, two-thirds of the women were aged 20-30 years. Only 48% attended their first preventive examination in pregnancy within the first 12 weeks. Their children subsequently presented with heterogeneous withdrawal symptoms, and pathological findings of the heart, urogenital and central nervous system. The present data aims to sensitize pediatric and obstetric health professionals to the need for timely and adequate care and support. A pathway model of detoxification treatment for mother and child - "The Dresden Crystal Path" - is presented. It combines public and voluntary youth welfare organizations, public health authorities, a public drugs advisory service as well as medical care facilities. Moreover, it describes the coordination of different medical subspecialties such as pediatrics, obstetrics/gynecology and psychiatry.

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.

A retrospective analysis of psychosocial risk factors modulating adolescent alcohol binge drinking.

BACKGROUND/AIMS: Adolescent alcohol binge-induced hospital admissions (BIHAs) are an increasing problem in Europe. We investigated whether psychosocial factors (e.g., drinking situations, drinking occasions and neighborhood unemployment) are associated with particularly risky patterns of alcohol or substance use. METHOD: We performed a systematic retrospective chart review of all the respective cases in 2003-2008 (n = 586; age range: 12-17 years) from both pediatric hospitals in the city of Dresden, Germany. RESULTS: The vast majority of adolescent BIHAs were associated with drinking together with peers at weekend parties. Compared to this 'typical' drinking pattern, adolescents drinking 'atypically' (i.e., drinking either alone, to cope or despite the fact that the next day was a school/work day) more often had already used alcohol and illegal substances before and were more often diagnosed with substance use disorders and other mental disorders prior to BIHA. The unemployment rate in the patients' neighborhood was positively related to the incidence proportion of adolescent BIHAs in the respective subdistricts (r(s) = 0.61). CONCLUSION: Adolescent atypical drinking may indicate an increased risk for the development of alcohol and substance use disorders. This information is quickly accessible and can alert clinicians to initiate psychosocial aftercare; their infrastructure should address the strong relation between BIHA probability and neighborhood unemployment rates.

Hypothenar hammer syndrome: a multicenter case-control study.

BACKGROUND: The rarely diagnosed hypothenar hammer syndrome (HHS) is due to vascular damage to the distal part of the ulnar artery probably caused by acute or repetitive blunt trauma to the hypothenar region. To date, mainly case reports have been published, while epidemiological data are almost absent. AIM: To identify potential risk factors for HHS. METHOD: An interview-based multicenter case-control study of 71 patients with HHS and 105 matched controls was conducted with standardized questions regarding disease specific variables, occupation, exposure of the hands to different types of trauma in occupational and leisure context. Medical data were verified from individual medical records. RESULTS: Multivariable logistic regression analysis revealed that using the hand as a hammer on a daily basis (adjusted odds ratio [aOR] 17.04, 95% CI 5.51-52.67) daily pressure to the palm of the hand (aOR 4.96, 95% CI 1.39-17.71), and daily exposure to vibrating tools (aOR 3.41, 95% CI 1.03-11.31) were significant risk factors for HHS. CONCLUSIONS: This investigation represents one of the largest groups of patients with HHS described so far. Work-related repeated blunt trauma to the palm of the hand significantly increases the risk of HHS.
