Educational interventions to prevent paediatric abusive head trauma in babies younger than one year old: A systematic review and meta-analyses

BackgroundPaediatric abusive head trauma (AHT) occurs in young children due to violent shaking or blunt impact. Educational and behavioural programmes modifying parent/infant interactions may aid primary prevention. This systematic review aims to assess the effectiveness of such interventions to prevent AHT in infants. MethodsWe searched Embase, MEDLINE, PsycINFO, The Cochrane library, CINAHL databases and trial registries to September 2021, for studies assessing the effectiveness of educational and behavioural interventions in preventing AHT. Eligible interventions had to include messaging about avoiding or dangers of infant shaking. Randomised controlled trials (RCTs) reporting results for primary (AHT, infant shaking) or secondary outcomes (including parental responses to infant crying, mental wellbeing), and non-randomised studies (NRSs) reporting primary outcomes were included. Evidence from combinable studies was synthesised using random-effects meta-analyses. Certainty of evidence was assessed using GRADE framework. PROSPERO registration CRD42020195644. FindingsOf 25 identified studies, 16 were included in meta-analyses. Five NRSs reported results for AHT, of which four were meta-analysed (summary odds ratio [OR] 0.95, 95 % confidence intervals [CI] 0.80–1.13). Two studies assessed self-reported shaking (one cluster-RCT, OR 0.11, 95 % CI 0.02–0.53; one cohort study, OR 0.36, 95 % CI 0.20–0.64, not pooled). Meta-analyses of secondary outcomes demonstrated marginal improvements in parental response to inconsolable crying (summary mean difference 1.58, 95 % CI 0.11–3.06, on a 100-point scale) and weak evidence that interventions increased walking away from crying infants (summary incidence rate ratio 1.52, 95 % CI 0.94–2.45). No intervention effects were found in meta-analyses of parental mental wellbeing or other responses to crying. InterpretationLow certainty evidence suggests that educational programmes for AHT prevention are not effective in preventing AHT. There is low to moderate certainty evidence that educational interventions have no effect or only marginally improve some parental responses to infant crying.

The role of household composition of children diagnosed with abusive head trauma

BackgroundTo prevent abusive head trauma (AHT), many studies focus on understanding the risk factors. Few studies assess the role of household composition. ObjectiveTo describe the household composition of children diagnosed with AHT and assess the relationships between patient and household characteristics, perpetration, and fatality. Participants and settingChildren admitted to a large pediatric hospital with AHT between January 1, 2010 and December 31, 2019. MethodsThe diagnosis of AHT was made at initial hospitalization by a child abuse pediatrician with a multidisciplinary team review. The electronic medical records of identified patients were reviewed to identify demographic information, the number and ages of all of their siblings and the number and relationship to patients of all adults who were reported as being present at the time of AHT and therefore considered to be possible perpetrators. Descriptive statistics were used to characterize the sample. Comparisons were made using Fisher exact tests and Mann-Whitney tests. ResultsChildren with AHT who were under 12 months of age and had siblings in the home, particularly siblings under age 5, had greater odds of being injured by a biological parent.Children 12 months or older and children without siblings had greater odds of being injured by a boyfriend or girlfriend of their parent or guardian. ConclusionsIn cases of AHT, the possible perpetrator differed based on the presence of young siblings living in the home, which has important implications for AHT prevention.

Pediatric abusive head trauma: ThinkFirst national injury prevention foundation.

Background: Pediatric abusive head trauma (AHT) represents 80% of nonaccidental trauma deaths, remaining a lead cause of death among infants and young children. Furthermore, neurosurgical intervention can ameliorate damage from secondary injury, but we are currently unable to alter the impact of the primary injury. Thus, prevention through increased public awareness is imperative. This study identifies injuries and predictors of outcomes in pediatric AHT and highlights the importance of partnering with our community through ThinkFirst, a national injury prevention foundation, to educate parents and caregivers about prevention.Methods: This single-institution retrospective review identifies injuries and predictors of outcomes in pediatric AHT and highlights the importance of partnering with our community to raise awareness and educate parents and caregivers about prevention.Results: The number of pediatric AHT cases continues to steadily increase over time (P < 0.001), and over 70% of these patients are <1 year of age (P < 0.001). Patients suffering AHT have a mortality rate of nearly 10%. In addition to morbidity and mortality, the economic burden of caring for abused children is high as they often require high levels of care, long hospital stays, and extensive rehabilitation. Furthermore, Medicaid pays for nearly 80% of these patients.Conclusion: The population of patients with AHT is unique, and one that will benefit from continued efforts at increased multidisciplinary and public awareness. Prevention of AHT through awareness is critical. Through partnering with ThinkFirst, a national injury prevention foundation, we aim to educate parents and caregivers about prevention.

A Structured Review of the Literature on Abusive Head Trauma Prevention

We searched the US National Library of Medicine's PubMed, Google Scholar and the American Psychological Association's Psychinfo databases during September 2019 for citations and abstracts on abusive head trauma (AHT) and shaken baby syndrome prevention dated 1 January 2000 to 31 August 2019. We identified 53 empirical studies and performed a structured review to identify the effects of prevention, if any, on AHT. We identified three lines of investigation that have focused on: (i) strategies which teach parents how to respond to newborn crying and the dangers of shaking babies; (ii) community and public health factors; and (iii) professional education and practice. Most studies were observational, although a small number used sophisticated designs such as prospective or randomised controlled trials. We note other strengths and weaknesses of these articles and suggest future directions for research in each of these areas based on the current level of scientific inquiry.‘Identified 53 empirical studies and performed a structured review to identify the effects of prevention… on AHT’Key Practitioner Messages Research on AHT prevention is limited, although a growing research base supports teaching parents how to respond to newborn crying and about the dangers of shaking babies. Social care systems addressing provision of material and other support have positive effects on AHT rates. Professional education should improve practitioners' identification of families with increased risk and enhance AHT identification and treatment. Those wishing to prevent AHT should consider multilevel approaches and their own community needs, practice setting, and patient/client risk profiles when designing strategies.

Abusive Head Trauma through Shaking: Examination of the Perpetrators According to Dating of the Traumatic Event

Effective prevention of abusive head trauma (AHT) requires the identification of potential perpetrators. Current evidence suggests that infant shaking, as a mechanism of AHT, produces immediate symptoms, allowing for the dating of the event based on clinical symptoms. Determining precisely when symptoms occurred may help law enforcement to identify the perpetrator. We retrieved written legal statements and medical records from birth to age at diagnosis of 100 infants consecutively diagnosed with AHT through shaking (2011–17), using forensic expertise files. Timing of abuse allowed for the identification of perpetrators in 91 cases. All abusive events occurred inside a home (parent's or nanny's), never outdoors or in a public place, and always in the presence of only one adult. Approximately one‐third (n = 32) of the perpetrators were males (31 fathers) and two‐thirds (n = 59) were females: 49 of them were the infant's nanny and ten were the infant's mother. Infants were not described as crying habitually. Better knowledge of the context of AHT events and risk situations, including recent implementation of a new or unusual modality of childcare, and being the only adult in a home with an infant, should facilitate prevention, including targeted training and avoidance of situations associated with risk.Key Practitioner Messages Abusive events occur in the presence of a single adult, within the privacy of a home. First signs of abuse most commonly occur in a recent, therefore unusual, form of childcare. With rare exceptions, the perpetrator is either the nanny or one of the parents. Identification of the perpetrator and better knowledge of the context of abuse should allow improving targeted prevention.

Implementation of an Abusive Head Trauma Prevention Program Through Interdisciplinary Collaboration: A Pilot Study.

Shaken baby syndrome/abusive head trauma (SBS/AHT) is the leading cause of child abuse death. Our institution piloted an evidence-based educational program to increase nurse and caregiver knowledge about SBS/AHT. Nurses participated in a pretest survey, completed online implementation training, and then were given a posttest survey to determine the change in SBS/AHT knowledge. Once trained, nurses disseminated information to caregivers with children younger than 6 months. Caregivers (N = 87) watched an educational video, reviewed information in a booklet with a nurse, and participated in teach-back related to key points of the intervention in both a hospital and the community setting. Prior to the education, nurses (n = 115) scored 8.03 out of 10.00 on the SBS/AHT assessment. Following the intervention, nurses (n = 120) scored 9.00 out of 10.00 on the assessment, t(233) = -6.61, p < .001. During education, caregivers (n = 69) were able to recall 8.55 out of 12 key educational components. In the community setting, caregivers (n = 18) worked together to recall 12 out of the 12 key components. Caregivers were most likely to recall ways to comfort their crying baby (94%) and why shaking a baby is dangerous (93%). This pilot study significantly increased nurses' knowledge of SBS/AHT and provided education to caregivers about SBS/AHT.

Evaluation of the Period of PURPLE Crying: An Abusive Head Trauma Prevention Programme

Abusive head trauma (AHT) in infants is thought to be triggered by caregiver frustration with persistent crying. The Period of PURPLE Crying (POPC) is designed to educate parents about normal infant crying, strategies to use when infants cry and the dangers of shaking in an effort to decrease AHT. Studies evaluating the POPC have measured changes in parent knowledge and behaviour regarding infant crying. Our objective was to evaluate the POPC's effect on caregiver frustration with infant crying compared to standard discharge information (SDI). We taught paediatric interns and medical students rotating in the newborn nursery to deliver the POPC and discuss infant crying. New parents were pseudo‐randomised to receive SDI or the POPC plus SDI. Parents were contacted five‐to‐eight weeks after discharge and asked knowledge questions about infant crying as well as the number of times that they were frustrated by their infant's crying in the preceding week. Of 271 parents who consented to participate, 164 (61%) completed the survey. The POPC group answered two of the knowledge questions correctly more often than the control group (score differences: 17%, 95% confidence interval (CI) 3–32% and 21%, 95% CI 7–36%). However, parents reported frustration due to infant crying at similar rates between the control (55/80, 69%) and POPC (60/84, 71%) groups. Our results support previous findings that the POPC improves caregiver knowledge concerning infant crying. The POPC does not appear to affect caregiver frustration with crying.‘Our objective was to evaluate the POPC's effect on caregiver frustration with infant crying compared to standard discharge information’Key Practitioner Messages Instructing new parents about normal infant crying and the dangers of shaking an infant remains an important part of anticipatory guidance. The POPC is not more effective at reducing caregiver frustration with infant crying than standard discharge instructions. Future investigations should specifically aim to include male caregivers as recipients of the programme.

Cerebrospinal Fluid Interaction with Cerebral Cortex during Pediatric Abusive Head Trauma

AbstractAbusive head trauma is the leading cause of fatal brain injuries in children younger than 2 years. It is a preventable and severe form of physical child abuse often linked to the forceful shaking of an infant or toddler. Victims of abusive head trauma can suffer permanent neurological damage, resulting in developmental delay and disability. The long-term effects of abusive head trauma are difficult to diagnose and predict. In this model, we use a high-order finite element method paired with the most comprehensive and current head/brain model and next-generation smoothed particle hydrodynamics. This is one of the first fluid–structure interaction frameworks that uses fluid material properties to represent the cerebrospinal fluid (CSF) while including all major anatomical features of the brain. The interaction of CSF with the brain cortex during abusive head trauma is demonstrated during multiple shaking cycles. A comprehensive and precise model that calculates for the role of CSF in neurological trauma will be useful both in the prevention and treatment of abusive head trauma and the determination of prognosis and patient outcomes.

Inequities in Pediatric Abusive Head Trauma According to Neighborhood Social and Material Deprivation: A Population-Level Study in British Columbia, Canada.

To explore the relationship between neighborhood social and material deprivation and the rates of abusive head trauma (AHT), and whether it differs according to sex, and following the implementation of the Period of PURPLE Crying (PURPLE) program. A cross-sectional study design was applied to data from children 0 to 24 months old with a confirmed AHT diagnosis between 2005 and 2017 in British Columbia. Dissemination area-based social and material deprivation scores were assigned to residential areas, where AHT cases were recorded. Poisson regression models tested the relationship between deprivation scores and AHT rates, adding sex and pre-post program implementation as interaction terms. With each increase in material and social deprivation quintiles, AHT rates increased by 42% (95% CI [1.18, 1.72]) and 25% (95% CI [1.06, 1.51]), respectively, following a social gradient. AHT rate disparities between neighborhoods did not change following the PURPLE program implementation. This study stresses the need to provide additional AHT prevention services proportionately to the levels of neighborhood disadvantage, in addition to universal AHT programs, to successfully protect all children.

Epidemiology of abusive head trauma in West Virginia children

Few states have published statewide epidemiology of abusive head trauma (AHT). To examine the statewide epidemiology of AHT in West Virginia (WV), with the primary objective of establishing AHT incidence for comparison to national data, and to use as a baseline for comparison to incidence post-implementation of a statewide AHT prevention program. AHT cases in children less than 2 years old were identified from the 3 tertiary pediatric centers in WV. Cases were identified by using ICD-9 codes for initially identifying those with injuries which might be consistent with AHT, followed by medical record review to determine which of these met the criteria for inclusion as a case. Medical examiner data was used to find additional cases of AHT. Using the number of cases identified along with relevant census data, incidence of AHT was calculated. There were 120 cases of AHT treated in WV hospitals from 2000 to 2010, 100 of which were WV residents. The incidence was 36.1/100,000 children <1 year of age and was 21.9 cases per 100,000 children <2 years of age. Incidence in infants increased during the latter years (2006-2010) of the study to 51.8/100,000 compared to the incidence during 2000-2005, which was 24.0/100,000 (p < .01). Compared to US national, state and regional figures, the WV incidence of AHT was among the highest. In addition, the incidence of AHT increased significantly over the study period. Possible factors contributing to the rise in incidence are discussed.

Do we get the message through? Difficulties in the prevention of abusive head trauma

Many programs aim to prevent abusive head trauma throughout the USA, Europe, and in many other regions of the world. Most of these programs inform mothers shortly after delivery about the dangers of abusive head trauma. Effectiveness of these programs usually is measured by the increase of knowledge on abusive head trauma. Recent research showed, however that for effective primary prevention, a much broader approach might be necessary. But so far, there is no data that reports the knowledge on key messages on abusive head trauma in the general public as a baseline. We conducted a representative population-based survey on abusive head trauma knowledge in Germany. Whereas the dangers are generally well known, a majority might be ambivalent towards the recommendation to leave a crying infant alone for a few minutes when the caregiver becomes too stressed or frustrated. Furthermore, a majority prefers being informed on abusive head trauma before birth.Conclusion: Future preventive programs should focus on educating adolescents (potential baby sitters) and young adults when they do not yet have children of their own. What is known: • Most programs for primary prevention of abusive head trauma (AHT) focus on mothers shortly after delivery • There are no analyses so far of the quality of education programs in the general public, as educating mothers might not be sufficient to reduce incidence rates What is new: • Our study is the first population-based survey to measure the knowledge on AHT in a representative population sample and to provide the data base for targeted prevention programs. • The introduction of broader prevention programs might be necessary.

Assessment of Maternal Knowledge and Confidence About Abusive Head Trauma and Coping With Infant Crying Before and After Infant Safety Education in the Neonatal Intensive Care Unit.

Infants with a history of perinatal illness are at higher risk for abusive head trauma (AHT). Crying is a common trigger for physical abuse, and education on coping with infant crying is an important component of AHT prevention. This study assesses the effects of education in the neonatal intensive care unit (NICU) on mothers' knowledge about AHT and infant crying, self-efficacy in applying the education to infant cares and providing the education to others, and the quality of AHT and infant crying education after discharge. Mothers received a standardized education program about AHT and infant crying and completed a preeducation survey, posteducation survey, and 4- to 5-month follow-up survey. Overall, there was a sustained increase in knowledge (P < .001) and confidence (P < .001). Mothers who received verbal education reported a higher increase in confidence (P = .03). Few received information from healthcare providers about crying (35%) and AHT (20%) after discharge. At follow-up survey, most felt highly confident in their ability to share information about AHT (97%) and calm their infant (95%). Most had shared the education with others (77%). Education on AHT and crying in the NICU can produce sustained increases in mothers' knowledge and confidence, but the effectiveness may be improved by addressing unique barriers to education in this population.

Eight-year outcome of implementation of abusive head trauma prevention.

Low incidence rates and economic recession have hampered interpretation of educational prevention efforts to reduce abusive head trauma (AHT). Our objective was to determine whether the British Columbia experience implementing a province-wide prevention program reduced AHT hospitalization rates. A 3-dose primary, universal education program (the Period of PURPLE Crying) was implemented through maternal and public health units and assessed by retrospective-prospective surveillance. With parents of all newborn infants born between January 2009 and December 2016 (n = 354,477), nurses discussed crying and shaking while delivering a booklet and DVD during maternity admission (dose 1). Public health nurses reinforced Talking Points by telephone and/or home visits post-discharge (dose 2) and community education was instituted annually (dose 3). During admission, program delivery occurred for 90% of mothers. Fathers were present 74.4% of the time. By 2-4 months, 70.9% of mothers and 50.5% of fathers watched the DVD and/or read the booklet. AHT admissions decreased for <12-month-olds from 10.6 (95% CI: 8.3-13.5) to 7.1 (95% CI: 4.8-10.5) or, for <24-month-olds, from 6.7 (95% CI: 5.4-8.3) to 4.4 (95% CI: 3.1-6.2) cases per 100,000 person-years. Relative risk of admission was 0.67 (95% CI: 0.42-1.07, P = 0.090) and 0.65 (95% CI: 0.43-0.99, P = 0.048) respectively. We conclude that the intervention was associated with a 35% reduction in infant AHT admissions that was significant for <24-month-olds. The results are encouraging that, despite a low initial incidence and economic recession, reductions in AHT may be achievable with a system-wide implementation of a comprehensive parental education prevention program.

Prevention and recognition of abusive head trauma: training for healthcare professionals in Vietnam

This study presents results from an intervention designed to improve identification and response to abusive head trauma in a tertiary paediatric hospital in Vietnam. One hundred and sixteen healthcare professionals (paediatric medical and nursing staff) completed a clinical training programme and participated in its evaluation. A pre-post-test and follow-up design was used to evaluate the outcomes. Questionnaires were used to collect data prior to training, at six weeks and at six months. Generalised linear modelling was used to examine changes in diagnostic skills and knowledge of the consequences of shaken baby syndrome (SBS) (a form of abusive head trauma), its prevention and treatment. At baseline, awareness and knowledge reflected no former abusive head trauma training. Following the intervention, participants had an increased awareness of shaken baby syndrome and the potential consequences of shaking infants and had acquired techniques to inform parents how to manage the crying infant. The intervention was effective in raising awareness of shaken baby syndrome and its consequences amongst the participating healthcare professionals in Vietnam. Training can improve detection and prevention of abusive head trauma, and the intervention has the potential to be adapted for similar settings internationally.

Prevention of Pediatric Abusive Head Trauma

Prevention of Pediatric Abusive Head Trauma

The impact of an educational intervention on knowledge about infant crying and abusive head trauma.

Infants follow a predictable trajectory of increased early crying. Frustration with crying is reported to be a trigger for abusive head trauma (AHT). To evaluate the impact of postpartum delivery of the educational program, the Period of PURPLE Crying (PURPLE), in a group of first-time mothers. The primary objective was to determine whether there was a change in knowledge about infant crying and shaking after exposure to PURPLE. Factors associated with change in knowledge were also examined. A total of 93 participants were recruited over a four-month period at a tertiary care hospital in Nova Scotia. Pre- and postintervention data were collected. Knowledge about infant crying increased significantly after program delivery (P=0.001). Low baseline crying knowledge was a significant predictor of increased knowledge about infant crying (P≤0.01). There was an insignificant decrease in shaking knowledge (P=0.5), which may have been the consequence of high baseline knowledge. An educational program for new parents appears to be warranted, especially with respect to improving knowledge about infant crying. This may have a positive benefit in AHT prevention. Additional studies are required to evaluate the impact of the program on other caregivers and on rates of AHT.

Simulation of the Impact of Programs for Prevention and Screening of Pediatric Abusive Head Trauma.

Primary prevention programs of pediatric abusive head trauma (PAHT) exist and early screening is proposed, but negative effects of mislabeling parents as abusers, an important issue, are not well documented. The aim of our study was to simulate the possible impact of programs for the primary prevention and screening of PAHT. We developed Markov models that simulate the life histories of PAHT with no intervention, with primary prevention program only, with screening program, and with both programs in a hypothetical cohort of 800,000 newborns in a high-income country. Screening program would be addressed to all families until children are 2 years old, during repeated consultations. Potential side effects for parents being mislabeled as abusers were supposed to increase the probability of PAHT and decrease participation in screening. Time horizon was 2 years with cycles of 15 days. Outcomes were number of deaths and abused children avoided. Uncertainty was specified with probability distributions. After 2 years, the median number of deaths avoided through primary prevention would vary from 6 (95% confidence interval [CI] 2-11) to 28 (95% CI 6-51) per 100,000 newborns. Screening could prevent up to 6 (95% CI 0-29) or cause up to 66 (95% CI 0-361) deaths per 100,000 children born alive. The impact of both programs was uncertain. Our model confirmed the potential benefits of primary prevention and documented the uncertainty associated with screening of PAHT.

Effectiveness of a Statewide Abusive Head Trauma Prevention Program in North Carolina.

Abusive head trauma (AHT) is a serious condition, with an incidence of approximately 30 cases per 100,000 person-years in the first year of life. To assess the effectiveness of a statewide universal AHT prevention program. In total, 88.29% of parents of newborns (n = 405 060) in North Carolina received the intervention (June 1, 2009, to September 30, 2012). A comparison of preintervention and postintervention was performed using nurse advice line telephone calls regarding infant crying (January 1, 2005, to December 31, 2010). A difference-in-difference analysis compared AHT rates in the prevention program state with those of other states before and after the implementation of the program (January 1, 2000, to December 31, 2011). The Period of PURPLE Crying intervention, developed by the National Center on Shaken Baby Syndrome, was delivered by nurse-provided education, a DVD, and a booklet, with reinforcement by primary care practices and a media campaign. Changes in proportions of telephone calls for crying concerns to a nurse advice line and in AHT rates per 100,000 infants after the intervention (June 1, 2009, to September 30, 2011) in the first year of life using hospital discharge data for January 1, 2000, to December 31, 2011. In the 2 years after implementation of the intervention, parental telephone calls to the nurse advice line for crying declined by 20% for children younger than 3 months (rate ratio, 0.80; 95% CI, 0.73-0.87; P < .001) and by 12% for children 3 to 12 months old (rate ratio, 0.88; 95% CI, 0.78-0.99; P = .03). No reduction in state-level AHT rates was observed, with mean rates of 34.01 person-years before the intervention and 36.04 person-years after the intervention. A difference-in-difference analysis from January 1, 2000, to December 31, 2011, controlling for economic indicators, indicated that the intervention did not have a statistically significant effect on AHT rates (β coefficient, -1.42; 95% CI, -13.31 to 10.45). The Period of PURPLE Crying intervention was associated with a reduction in telephone calls to a nurse advice line. The study found no reduction in AHT rates over time in North Carolina relative to other states. Consequently, while this observational study was feasible and supported the program effectiveness in part, further programmatic efforts and evaluation are needed to demonstrate an effect on AHT rates.
