Association of Household Deprivation, Comorbidities, and COVID-19 Hospitalization in Children in Germany, January 2020 to July 2021.

Importance: Adults in disadvantaged socioeconomic positions have elevated risks of a severe course of COVID-19, but it is unclear whether this holds true for children. Objective: To investigate whether young people from disadvantaged households have a higher risk of COVID-19 hospitalization and whether differences were associated with comorbidities that predispose children to severe courses. Design, Setting, and Participants: This population-based cohort study included all children and adolescents (aged 0-18 years) who were enrolled in a statutory health insurance carrier in Germany during the observation period of January 1, 2020, to July 13, 2021. Logistic regressions were calculated to compare children from households with and without an indication of poverty. Age, sex, days under observation, nationality, and comorbidities (eg, obesity, diabetes) were controlled for to account for explanatory factors. Exposures: Disadvantage on the household level was assessed by the employment status of the insurance holder (ie, employed, long- or short-term unemployed, low-wage employment, economically inactive). Socioeconomic characteristics of the area of residence were also assessed. Main Outcomes and Measures: Daily hospital diagnoses of COVID-19 (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes U07.1 and U07.2) were recorded. Comorbidities were assessed using inpatient and outpatient diagnoses contained in the insurance records. Results: A total of 688 075 children and adolescents were included, with a mean (SD) age of 8.3 (5.8) years and 333 489 (48.4%) female participants. COVID-19 hospital diagnosis was a rare event (1637 participants [0.2%]). Children whose parents were long-term unemployed were 1.36 (95% CI, 1.22-1.51) times more likely than those with employed parents to be hospitalized. Elevated odds were also found for children whose parents had low-wage employment (odds ratio, 1.29; 95% CI, 1.05-1.58). Those living in low-income areas had 3.02 (95% CI, 1.73-5.28) times higher odds of hospitalization than those in less deprived areas. Comorbidities were associated with hospitalization, but their adjustment did not change main estimates for deprivation. Conclusions and Relevance: In this cohort study, children who had parents who were unemployed and those who lived in low-income areas were at higher risk of COVID-19 hospitalization. This finding suggests that attention must be paid to children with SARS-CoV-2 from vulnerable families and closer monitoring should be considered. A number of explanatory factors, including comorbidities, were taken into account, but their analysis yielded no clear picture about underlying processes.

Necrotizing enterocolitis and focal intestinal perforation in neonatal intensive care units in the state of baden-württemberg, Germany.

In preterm infants with very low birth weight (VLBW) <1500 g the most important acquired intestinal diseases are necrotising enterocolitis (NEC) and focal intestinal perforation (FIP). We analyzed data of the neonatology module of national external comparative quality assurance for inpatients in the state of Baden-Württemberg, Germany. Between 2010 and 2012, 59 of 3549 VLBW infants developed FIP (1.7%), 128 of them NEC (3.6%). In approximately 3% of infants with BW<1000 g FIP was diagnosed, which was nearly 9 times more often than in infants with BW between 1250 and 1499 g (FIP frequency 0.36%). NEC frequency increased with decreasing BW and was more than 10 times higher in the smallest infants (BW<750 g: 7.87%) compared to those with BW between 1250 and 1499 g (0.72%). The BW limit of 1250 g differentiates between groups of patients with distinguished risks for NEC and FIP.

[Why does evidence-based medicine need the international classification of functioning, disability, and health?]. / Wozu braucht evidenzbasierte Medizin die ICF, die Internationale Klassifikation der Funktionsfähigkeit, Behinderung und Gesundheit?

OBJECTIVE: Evidence-based medicine (EBM) aims at finding the currently best answer to the questions raised by a patient's disease through rationally comparing different diagnostic and therapeutic alternatives. THESIS: As a rational method, EBM also needs a rational reference system. ICF, the International Classification of Functioning, Disability, and Health, officially translated into German in 2004, is such a reference system. DISCUSSION OF THE POSSIBLE ROLE OF THE ICF IN EBM: ICF, a supplementary classification to ICD, consists of the four components: body functions and body structures, activities and participation, environmental factors, and personal factors (not yet classified). ICF describes the interdependence between all the factors influencing health as well as disease. For EBM, ICF can serve as a reference system: when defining a therapy's goal and examining whether it was reached, for including and excluding criteria of target groups, checking whether control and intervention groups are comparable, finding out relevant prognostic factors, defining the requirement of an intervention, applying assessments, or grouping people with similar need of help for payment.
