An integrative review on the shadow of abuse in pediatric head trauma. Univ Med 44:257-269 ABSTRACT INTRODUCTION Abusive head trauma (AHT) is a significant public health issue that can lead to severe neurological damage or death in childhood. Often difficult to detect. AHT carries long-term consequences and requires high diagnostic This integrative review aims to synthesize the current evidence on abusive head trauma in pediatric patients by identifying distinguishing diagnostic criteria, clinical patterns, and risk factors, in order to support early recognition, accurate diagnosis, and effective intervention strategies by healthcare professionals. METHODS This integrative review aimed to systematically include studies published between 2020-2025 and the literature search was conducted in April-June 2025. The databases searched included PubMed and Web of Science. The keywords included in the search were "Abusive head trauma", "child abuse", "non-accidental head injury", "health care professional", "pediatric head trauma". The methodological quality of the included studies was assessed using the Risk of Bias in Non-randomized Studies Ae of Interventions (ROBINS-I) tool. RESULTS The findings were synthesized under four main themes: diagnostic indicators and differentiation, epidemiological risk factors, short-term clinical outcomes, and long-term developmental effects. Elevated glucose levels (>300 mg/dL), the diagnostic AutriadAy . ubdural hematoma, retinal hemorrhage, and encephalopath. , and increased plasma osteopontin levels were identified as critical diagnostic clues. Additionally, household composition and caregiver characteristics emerged as significant risk factors. CONCLUSION This integrative review highlights the necessity of identifying high-risk environments and implementing preventive strategies. The evidence presented offers practical, evidence-based insights to support healthcare professionals in accurately diagnosing and managing AHT. It also underscores the need for multidisciplinary prevention efforts and post-trauma monitoring. Ultimately, this study seeks to enhance clinical awareness and improve early identification and intervention strategies for children suffering from abuse-related head trauma.

Approximately 200,000 children are hospitalized annually due to HT, and 4,000 die within hours of the trauma. While trauma accounts for 15% of adult deaths, it contributes to nearly 50% of childhood mortality. Despite increased clinical awareness, distinguishing abusive head trauma from accidental injuries remains a major Head trauma is the most common cause of morbidity and mortality in children under the age of two. According to the lasgow Coma Scale (GCS). HT is classified as mild (GCS 14-. , moderate (GCS 9-. , or severe (GCS 3-. Common etiologies include sports injuries, falls, and motor vehicle accidents. Falls are especially prevalent in children under two due to immature walking skills, relatively larger head size, shifted center of gravity, and underdeveloped neck Though less common, non-accidental trauma . , abuse-related HT) constitutes a serious The Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP) recommend using the term "Abusive Head Trauma (AHT)" for trauma resulting from abuse. Abusive head trauma most frequently occurs in children under five and results from violent shaking, blunt force, suffocation, or being dropped or thrownAi typically by caregivers attempting to silence a crying child. Abusive head trauma is one of the primary causes of traumatic brain injury in early childhood, often going unrecognized but with lifelong consequences. Caregivers frequently deny any harmful event, offering alternative explanations such as falling from stairs, high chairs, or being pushed by a sibling. This obscures the true etiology and delays diagnosis. Therefore, it is vital for healthcare professionals to recognize the distinguishing signs and symptoms of AHT for timely intervention. ,10,11,14,. Various intracranial and ophthalmologic findingsAisuch as subdural hematoma, retinal hemorrhage, and cerebral edemaAihave been identified as potential indicators of abuse. However, no single finding is pathognomonic, and clinical presentations often overlap with accidental injuries, making misdiagnosis a persistent risk. These diagnostic ambiguities are further complicated by inconsistent histories provided by caregivers and limited external signs of trauma. This integrative review aimed to conduct a thorough assessment of the available evidence on AHT, focusing on: 1. confusion, 2. clinical dilemmas, and 3. METHODS Research type and strategy This integrative review systematically examined the literature published between 2020 and 2025 to identify key indicators that help differentiate abuse-related injuries in pediatric head trauma cases. The literature search was conducted between April and June 2025. PubMed and Web of Science were used as the databases. The keywords employed included Auabusive head trauma,Ay Aunon-accidental head injury,Ay Auchild abuse,Ay and Aupediatric head trauma. Boolean operators AuANDAy and AuORAy were used to combine and refine search terms. To map the search process, a flow diagram was used PRISMA . flow diagram (Figure . Inclusion and exclusion criteria The inclusion and exclusion criteria were essential for ensuring the methodological integrity of the review and for evaluating the literature These criteria are presented in Table 1. Selection process To minimize bias, the selection process was carried out by two independent researchers. Discrepancies and inconsistencies between reviewers were resolved through consultation with a third independent reviewer. The keywords and inclusion/exclusion criteria guided the screening Only full-text English-language articles were included for eligibility assessment. The PRISMA flow diagram showing the selection process is presented in Figure 1. The Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) tool was used to assess study . According to the ROBINS-I evaluation, seven studies were found to have Abuse in pediatric head trauma moderate risk and four had low risk of bias (Supplementary Table . Figure 1.

A standardized data extraction form was used to ensure completeness, transparency, and consistency across all included studies. Extracted data included study design, country, sample characteristics, aims, outcome variables, and key The analysis proceeded in two main stages. First, a descriptive summary of the included studies was created, detailing their methodological and contextual features. Second, thematic analysis was employed to identify and categorize patterns within the data. The analysis was conducted in a stepwise manner to ensure rigor, and conceptual mapping was used to align thematic findings with clinical practice implications. All analytical steps were planned a priori to reduce bias and enhance methodological transparency. RESULTS Study characteristics This integrative review included 11 studies covering abusive head trauma in children and published between 2020 and 2025 . 0=2. 2022=4. 2023=3. The majority of these studies were conducted in the USA, with one study SONGUT S in Taiwan,. and one study in the Netherlands. It was determined that the sample sizes of the included studies varied widely, with the smallest sample being 47 . and the largest sample being 20,540. When the population of the studies was examined, it was determined that all of the studies included children . -18 years ol. , and especially children under 3 years old and infants (<12 month. constituted the study populations. Studies have focused on patients diagnosed with craniofacial trauma, traumatic brain injury (TBI), and particularly AHT. Almost all of the studies were conducted with a retrospective design. Only two studies . were cohort studies. The main focuses of the clinical/biomarkers/radiological findings helpful in the diagnosis of abuse,. ,32-. epidemiological features and risk factors of abuse,. clinical outcomes and prognosis of abuse,. long-term developmental/behavioral abuse,. and classification of abuse-related injuries with mathematical/clinical patterns. The characteristics of the studies included in the research are presented in Table 2. short term has been emphasized. Gomez et al. reported that in-hospital mortality rates were Lee et al. associated initial findings such as shock, hypothermia, and post-traumatic seizures with poor prognosis. Orman et al. showed a strong association of specific neuroimaging findings . specially hypoxicischemic injur. with death and poor neurological outcomes in their studies. Thematic synthesis of studies The findings of the studies were examined under four main themes. Distinguishing findings Hyperglycemia: Initial glucose levels >300 mg/dL have been described as a very strong indicator of abuse, especially in young children. This finding is a critical Aured flagAy for clinicians in raising suspicion of abuse. Classic AutriadAy finding: The combination of subdural hematoma, retinal hemorrhage, and encephalopathy has been validated as a diagnostic triad with high specificity for AHT. The diagnosis of abuse is highly likely in the presence of this triad. Diagnostic clues and discrimination Studies have highlighted critical diagnostic clues in distinguishing AHT from accidental Among these, hyperglycemia,. the "triad": subdural hematoma, retinal hemorrhage, encephalopathy . intraventricular hemorrhage, widespread axonal injury, hypoxic-ischemic injury, spinal injury . and increased osteopontin. have been prominent. In the studies of Boos et al. it has been shown that the mathematical clustering of clinical findings is similar to the distinctive findings of abuse cases. Epidemiology and risk factors It has been stated that the risk of AHT increases in infants (<12 month. , in the presence of a sibling under the age of 5 and in biological In older children (>12 month. and in those without a sibling, the risk of abuse by the parent's boyfriend/girlfriend has been reported to . Clinical course and short-term outcomes The association of AHT with poor neurological outcomes and risk of death in the Long-term developmental and behavioral Attention has been drawn to the long-term devastating effects of AHT. Children who underwent AHT have been reported to have significant delays and deficiencies in fine motor skills, personal-social development, socioemotional areas, and cognitive and language . Moderate injuries are more . Rehabilitation services should be provided in this its role in improving negative outcomes has been emphasized. A summary of the thematic synthesis of the studies is presented in Table 3. Specific Classic findings: Subdural hematoma is the most common classical finding. Non-classic findings: Bridging vein thrombosis is the most common non-classic finding. Poor prognostic indicators: The combination of intraventricular hemorrhage, diffuse axonal injury, hypoxic-ischemic injury, arterial stroke, and spinal ligamentous injury is strongly associated with poor neurological outcome and .

Children with AHT may experience mild, nonspecific symptoms such as vomiting, irritability, lethargy, poor feeding, or trouble . However, many children with AHT do not exhibit external signs of head trauma, such as scalp swelling. Therefore, healthcare professionals should have a high level of knowledge and awareness that injuries in children brought to healthcare institutions affiliated with HT may be due to abuse. Accordingly, this integrative review systematically synthesizes the existing literature in the field of child abuserelated head trauma (AHT) by: . analyzing the Supporting Randall et al. Blackwell et al. Gomez et al. Hymel et al. Orman et al. Boos et al. Eismann et al. Gomez et al. Lee et al. Orman et al. Eismann et al. Keenan et al. Keenan et al. visibility dynamics of AHT in scientific publications over the last five years, . identifying priority research focuses and conceptual trends, . revealing knowledge gaps in diagnostic approaches. The evidence obtained provides practical frameworks to strengthen healthcare professionals' diagnostic awareness. Following a brain injury, brain tissue releases various chemicals into the cerebrospinal fluid (CSF). The bloodAebrain barrier temporarily becomes more permeable, which allows these substances to enter the bloodstream. Studies have shown that CSF markers are elevated in young children after inflicted head trauma. Orman et al. supported this information and stated that the AuTriad SignAy . ubdural hematoma retinal hemorrhage encephalopath. continues to be the gold standard in diagnostic specificity. SONGUT S Similarly. Boos et al. also supported this information in their research. In addition to this information. Hymel et al. stated that nonclassical findings such as bridging vein thrombosis can be seen in their research and it has been shown that they can be helpful in diagnosis. Different from these findings. Randall et al. in their research, it was stated that all young children with intracranial hemorrhage and initial glucose levels higher than 300 mg/dL were victims of abuse, and this threshold could be used as a "red code" in emergency services. Blackwell et al. who evaluated a different finding in their research, showed that the increase in osteopontin (OPN) specific to abuse could be used to develop blood test-basd screening protocols. In light of these findings, in cases where abuse is suspected but a definitive diagnosis cannot be made. in addition to the judicial reporting process, triple findings, and social service consultations, examining glucose and OPN levels with blood tests can help make a definitive diagnosis, and therefore simultaneous evaluations are recommended. Risk factors for AHT include behaviors involving the child, family, and caregiver. Severe shaking of the crying child by the child's parent/caregiver in order to quiet the child may cause shaken baby syndrome. However, many factors such as having a large number of children in the family, lack of prenatal care, low level of education, low socioeconomic status, singleparent families, stepmother/father, etc. the risk factors for AHT. A detailed diagnostic evaluation is necessary in AHT cases. The first symptoms include decreased interaction in children, lack of social smile, poor feeding, vomiting, lethargy, hypothermia, increased need for sleep, and developmental delay. More severe trauma findings are the emergence of life-threatening signs and symptoms. Gomez et al. reported that the in-hospital mortality rate was 6. 78% in their . Orman et al. stated that the combination of intraventricular hemorrhage, widespread axonal injury, hypoxic-ischemic injury, arterial stroke, and/or spinal ligamentous injury were poor prognostic indicators. Similar to this finding. Lee et al. found that initial symptoms starting with shock were associated with hypothermia and post-traumatic seizure, poor neurological outcomes, and mortality. In addition to these clinical findings. AHT caused neurological damage and negatively affected the later lives of children. Keenan et al. and Eismann et al. However, while Keenan et al. reported that rehabilitation services could improve these negative outcomes. Eismann et . did not find a significant relationship between early therapeutic interventions and developmental, behavioral or quality of life This difference between Keenan et . and Eismann et al. studies was thought to be due to the characteristics of the sample groups and/or different follow-up periods of the studies, and showed that more research is needed in this In addition, these findings have shown how important prevention interventions are. Among the preventive factors. providing awareness training to the community about the short- and long-term outcomes of AHT, parental education on child development and parenting, providing social support, and increasing parental resilience can be recommended. Implications for health care professionals, research and education The most important factor in preventing AHT is awareness training for caregivers and training for health professionals to recognize signs and All health care professionals should be able to recognize suspected child abuse and neglect, report it, and take appropriate action, such as informing judicial institutions. While the diagnosis of abusive head trauma is sometimes unsuspecting clinicians may fail to recognize injuries caused by child abuse. In addition, when the diagnosis is unclear, suspicion should continue until the evaluation is completed. Based on this integrative review, we propose the following recommendations. First, healthcare professionals should pay attention to clinical and biochemical findings at the time of application to detect the possibility of abuse early and initiate the necessary reporting processes. Second, children with suspected AHT should be evaluated holistically with neuroimaging, ophthalmological evaluation and blood biomarkers. And finally, long-term follow-up and rehabilitation services neurodevelopmental problems in children who have AHT. This integrative review has several strengths. First, it focuses on a highly specific and clinically significant issueAiabusive head trauma in patientsAiaddressing confusion, clinical dilemmas, and missed outcomes, which are often underexplored in Abuse in pediatric head trauma existing literature. Second, the review includes studies published between 2020 and 2025, ensuring that the findings reflect the most current Third, the use of a systematic approach to data extraction and the application of the ROBINS-I tool to assess methodological quality enhanced the rigor and reliability of the synthesis. Additionally, the identification of clear diagnostic indicators and clinically relevant themes offers practical implications for healthcare professionals working in pediatric emergency and forensic However, the study also has some Only two databases (PubMed and Web of Scienc. were used, which may have led to the exclusion of relevant studies indexed Other limitations are also presented below: . Study design heterogeneity: the majority of included studies . =9/. were conducted in a retrospective design. Such studies carry the risk of data recording deficiencies and selection bias. The paucity of prospective or randomized controlled trials limits the interpretation of causal relationships. Geographic and cultural limitations: Nine of the reviewed studies were based in the USA, only 1 was conducted in Taiwan and 1 in the Netherlands. This suggests that the findings may have been influenced by socioeconomic, legal, and cultural factors, questioning the universal generalizability of the results. Clinical applicability of biomarkers: Promising biomarkers such as osteopontin (OPN) have only been tested in a single study. Multicenter studies are needed to translate these findings into routine clinical use. The acknowledgements are applicable for this review. CONCLUSIONS Abusive head trauma (ACT) is a critical condition that can have severe consequences in pediatric patients. This study provides up-to-date data that will guide healthcare professionals in determining diagnostic markers, clinical patterns, and risk factors for ACT. In particular, glucose >300 mg/dL, the Autriple signAy . ubdural hematoma, retinal hemorrhage, encephalopath. , and high osteopontin levels stand out as important indicators in diagnosis.
