A recent study reveals that explicit coding of child physical abuse in German hospitals remains rare, highlighting ongoing underreporting despite increased safeguarding efforts and broader data indicators.
Administrative coding for child physical abuse in German hospitals remained uncommon from 2019 to 2024, even as broader indicators of maltreatment and safeguarding activity became more visible in hospital records, according to a study published in the European Journal of Pediatrics. The researchers analysed more than 11.3 million inpatient cases involving children and adolescents and found that explicit abuse diagnoses accounted for only about 0.3% of admissions.
The study, led by Teresa Walter at University Hospital Ulm, suggests that hospitals are still capturing only a narrow slice of the problem in administrative data. While the specific abuse code showed a decline, broader assessment, psychosocial and procedural safeguarding codes all increased over the study period. Earlier work on German hospital data has reached a similar conclusion, describing systematic underreporting and warning that only a small fraction of suspected cases are formally documented.
The pattern of injuries in coded cases also points to how abuse is recognised in hospital settings. Most of the admissions with abuse-related coding involved head injuries, especially concussion and subdural haemorrhage. Among children aged 0 to 2 years admitted with fractures or haematomas, the explicit physical abuse code was uncommon, underscoring the difficulty of relying on billing and discharge data alone to identify maltreatment. Related research has found that under-coding is driven in part by limited training and inconsistent awareness among clinicians, and that the true incidence is likely higher than hospital figures suggest.
The authors said clearer coding guidance, staff training and harmonised European definitions are needed if administrative data are to become a reliable surveillance tool. They also noted that the transition to ICD-11, the next version of the International Classification of Diseases, will take years in many countries. That caution aligns with other German analyses showing a wide gap between hospital documentation and prevalence estimates derived from population-based studies.
