Child Deaths Resulting From Inflicted Injuries: Household Risk Factors and Perpetrator Characteristics

Objective. To determine the role of household composition as an independent risk factor for fatal inflicted injuries among young children and describe perpetrator characteristics. Design, Setting, and Population. A population-based, case-control study of all children <5 years of age who died in Missouri between January 1, 1992, and December 31, 1999. Missouri Child Fatality Review Program data were analyzed. Cases all involved children with injuries inflicted by a parent or caregiver. Two age-matched controls per case child were selected randomly from children who died of natural causes. Main Outcome Measure. Inflicted-injury death. Household composition of case and control children was compared by using multivariate logistic regression. We hypothesized that children residing in households with adults unrelated to them are at higher risk of inflicted-injury death than children residing in households with 2 biological parents. Results. We identified 149 inflicted-injury deaths in our population during the 8-year study period. Children residing in households with unrelated adults were nearly 50 times as likely to die of inflicted injuries than children residing with 2 biological parents (adjusted odds ratio: 47.6; 95% confidence interval: 10.4–218). Children in households with a single parent and no other adults in residence had no increased risk of inflicted-injury death (adjusted odds ratio: 0.9; 95% confidence interval: 0.6–1.9). Perpetrators were identified in 132 (88.6%) of the cases. The majority of known perpetrators were male (71.2%), and most were the childs father (34.9%) or the boyfriend of the childs mother (24.2%). In households with unrelated adults, most perpetrators (83.9%) were the unrelated adult household member, and only 2 (6.5%) perpetrators were the biological parent of the child. Conclusions. Young children who reside in households with unrelated adults are at exceptionally high risk for inflicted-injury death. Most perpetrators are male, and most are residents of the decedent childs household at the time of injury.

Child death review. The state of the nation.

BACKGROUND Child death review (CDR) is a mechanism to more accurately describe the causes and circumstances of death among children. The number of states performing CDR has more than doubled since 1992, but little is known about the characteristics of these programs. The purpose of this study was to describe the current status of CDR in the United States and to document variability in program purpose, scope, organization, and process. METHODS Investigators administered a written survey to CDR program representatives from 50 states and the District of Columbia (DC), followed by a telephone interview. RESULTS All 50 states and DC participated; 48 states and DC have an active CDR program. A total of 94% of programs agreed that identifying the cause of and preventing future deaths are important purposes of CDR. Assistance with child maltreatment prosecution was cited as an important purpose by only 13 states (27%). Twenty-two states (45%) review deaths from all causes, while six states (12%) review only deaths due to child maltreatment. CDR legislation exists in 33 states. Fifty-three percent of the CDR programs were implemented since 1996, and 59% report no or inadequate funding. CDR contributes to the death investigation process in seven states (14%), but the majority (59%) of reviews are retrospective, occurring months to years after the childs death. CONCLUSIONS CDR programs in the United States share commonalities in purpose and scope. Without national leadership, however, the wide variation in organization and process threatens to limit CDR effectiveness.

Public Health Surveillance of Fatal Child Maltreatment: Analysis of 3 State Programs

OBJECTIVES We sought to describe approaches to surveillance of fatal child maltreatment and to identify options for improving case ascertainment. METHODS Three states--California, Michigan, and Rhode Island--used multiple data sources for surveillance. Potential cases were identified, operational definitions were applied, and the number of maltreatment deaths was determined. RESULTS These programs identified 258 maltreatment deaths in California, 192 in Michigan, and 60 in Rhode Island. Corresponding maltreatment fatality rates ranged from 2.5 per 100,000 population in Michigan to 8.8 in Rhode Island. Most deaths were identified by child death review teams in Rhode Island (98%), Uniform Crime Reports in California (56%), and child welfare agency data in Michigan (44%). Compared with the total number of cases identified, child welfare agency (the official source for maltreatment reports) and death certificate data underascertain child maltreatment deaths by 55% to 76% and 80% to 90%, respectively. In all 3 states, more than 90% of cases ascertained could be identified by combining 2 data sources. CONCLUSIONS No single data source was adequate for thorough surveillance of fatal child maltreatment, but combining just 2 sources substantially increased case ascertainment. The child death review team process may be the most promising surveillance approach.

Sudden unexpected infant deaths: sleep environment and circumstances.

OBJECTIVES We sought to describe the characteristics and sleep circumstances of infants who die suddenly and unexpectedly and to examine similarities and differences in risk factors among infants whose deaths are classified as resulting from sudden infant death syndrome (SIDS), suffocation, or undetermined causes. METHODS We used 2005 to 2008 data from 9 US states to assess 3136 sleep-related sudden unexpected infant deaths (SUIDs). RESULTS Only 25% of infants were sleeping in a crib or on their back when found; 70% were on a surface not intended for infant sleep (e.g., adult bed). Importantly, 64% of infants were sharing a sleep surface, and almost half of these infants were sleeping with an adult. Infants whose deaths were classified as suffocation or undetermined cause were significantly more likely than were infants whose deaths were classified as SIDS to be found on a surface not intended for infant sleep and to be sharing that sleep surface. CONCLUSIONS We identified modifiable sleep environment risk factors in a large proportion of the SUIDs assessed in this study. Our results make an important contribution to the mounting evidence that sleep environment hazards contribute to SUIDs.

Household Composition and Fatal Unintentional Injuries Related to Child Maltreatment

PURPOSE To determine if household composition is an independent risk factor for fatal unintentional injuries related to child maltreatment. DESIGN A population-based, case-control study using data from the Missouri Child Fatality Review Program for 1992-1999. METHODS Children under age five who died during the 8-year study period were eligible for study. Cases were defined as children who died of an unintentional injury that occurred when a parent or other adult caregiver: (a) was not present, (b) was present but not capable of protecting the child, (c) placed the child in an unsafe sleep environment, or (d) failed to use legally mandated safety devices. Controls were randomly selected from children who died of natural causes. Household composition was classified based on relationship of the adults living in the household to the deceased child. The five household composition categories were households with: (a) two biologic parents and no other adults, (b) one biologic parent and no other adults, (c) one or two biologic parents and another adult relative, (d) stepparents or foster parents, and (e) one or two biologic parents and another unrelated adult. Logistic regression analyses were conducted and odds ratios estimating the risk of maltreatment-related unintentional death associated with each household category compared to the reference households: those with two biologic parents and no other adults. FINDINGS Three hundred eighty children met the case definition. Children residing within households with adults unrelated to them had nearly six times the risk of dying of maltreatment-related unintentional injury (adjusted odds ratio [aOR] 5.9; 95% confidence interval [95% CI] 1.9-17.6). Children residing with step or foster parents and those living with other, related adults were also at increased risk of maltreatment death (aOR 2.6, 95% CI 1.0-6.5; and aOR 2.1, 95% CI 1.0-4.5, respectively). Risk was not elevated for children in households with a single biologic parent and no other adults in residence. CONCLUSIONS Young children residing in households with unrelated adults, step-parents, or foster parents are at increased risk of fatal unintentional injury related to maltreatment. Nurses can use the findings of this study to facilitate injury prevention by identifying families at risk for fatal unintentional injuries and providing these families with targeted education or referral.

Identification of ICD codes suggestive of child maltreatment

OBJECTIVE In order to be reimbursed for the care they provide, hospitals in the United States are required to use a standard system to code all discharge diagnoses: the International Classification of Disease, 9th Revision, Clinical Modification (ICD-9). Although ICD-9 codes specific for child maltreatment exist, they do not identify all maltreatment-related hospital and emergency department discharges. To increase the usefulness of medical data for public health surveillance of child maltreatment, this project sought to identify ICD-9 codes that are suggestive of child maltreatment. METHODS After review of the literature and discussions with experts, injuries and conditions that should raise suspicion of child maltreatment (physical or sexual abuse or neglect) were identified and a list of corresponding ICD codes was compiled. Using a statewide electronic database of hospital discharges and emergency department (ED) visits for the year 2000, visits by children assigned these ICD codes were identified, a sample of visits was selected, and medical records were reviewed to assess the circumstances of the injury or illness that led to the visit. Based on information in the medical record, the injury or illness was classified as maltreatment-related, or not. RESULTS There were 3,684 visits selected for review. Of these, 2,826 records were reviewed and classified; 1,200 (43%) records met the criteria for being maltreatment-related, 1,419 (50%) contained adequate information indicating the injury/condition was not likely maltreatment-related, and 207 (7%) records did not contain enough information to classify. Sixty-eight ICD codes had >66% of visits classified as maltreatment-related, the a priori criteria for a code to be considered suggestive of maltreatment. Codes suggestive of maltreatment include specific fractures, burns, and injuries of undetermined intent, among others. CONCLUSION Several ICD codes were found that, when used with age restrictions and other specific exclusion criteria, are suggestive of maltreatment. This information may increase the usefulness of hospital discharge data for public health surveillance of child maltreatment. PRACTICE IMPLICATIONS Use of these suggestive codes facilitates identifying conditions and injuries that are likely maltreatment-related in hospital discharge and ED visit data. When used in conjunction with ICD maltreatment-specific codes, these suggestive codes may enhance the use of medical data for monitoring child maltreatment trends.

Supervision and risk of unintentional injury in young children

Objective Assess the association between caregiver supervision and acute unintentional injury in young children; evaluate whether lower levels of supervision result in more severe injury. Methods A case cross-over study was conducted. Parents of children aged ≤4 years whose injuries required emergency department (ED sample) treatment or admission to the hospital (inpatient sample) were interviewed. Information on supervision (3 dimensions: proximity, attention, continuity) at the time of injury and 1 h before the injury (control time) was collected. An overall supervision score was created; a higher score indicates closer supervision. Hospital admission served as a proxy for injury severity. ORs and 95% CIs were calculated. Results Interviews were completed by 222 participants; 50 (23%) were in the inpatient sample. For each supervision dimension the inpatient sample had higher odds of injury, indicating effect modification requiring separate analyses for inpatient and ED samples. For both samples, proximity ‘beyond reach’ was associated with the highest odds of injury; compared with 1 h before injury, children were more likely to be beyond reach of their caregiver at the time of injury (inpatient sample: OR 11.5, 95% CI 2.7 to 48.8; ED sample: OR 2.9, 95% CI 1.8 to 4.9). Children with lower supervision scores had the greatest odds of injury (inpatient sample: OR 8.0, 95% CI 2.4 to 26.6; ED sample: OR 3.3, 95% CI 1.9 to 5.6). Conclusions Lower levels of adult supervision are associated with higher odds of more severe injury in young children. Proximity is the most important supervision dimension for reducing injury risk.

Association of injury visits in children and child maltreatment reports.

Injuries are a leading cause of childhood morbidity and are also common manifestations of child maltreatment, especially among young children. In an effort to determine whether injury-related Emergency Department (ED) visits among children aged 0 to 4 years were associated with child maltreatment reports, we identified all children with at least one injury-related ED visit in Missouri during 2000. Data on these injured children were linked to Missouri Child Protective Services (CPS) child abuse and neglect reports for 2000 and 2001. There were 50,068 children with at least one injury-related ED visit. Using children with one injury-related ED visit as the reference category, we calculated the relative risk of having a CPS report (or a substantiated report) for children with two, three, and four or more ED visits before a CPS report (or substantiated report). Compared to children with one visit, children with two visits were more likely to have a CPS report (relative risk [RR] 1.9; 95% confidence interval [CI] 1.8-2.0) and a substantiated report (RR 2.5; 95% CI 2.1-2.9). For children with four or more visits, the relative risk of a report and substantiated report was 3.8 (95% CI 3.0-4.7) and 4.7 (95% CI 2.4-9.2), respectively. Children with two or more injury-related ED visits in 1 year are more likely to be reported for child maltreatment and to have a substantiated report.

Public health efforts to build a surveillance system for child maltreatment mortality: lessons learned for stakeholder engagement.

CONTEXT Reducing the number of largely preventable and tragic deaths due to child maltreatment (CM) requires an understanding of the magnitude of and risk factors for fatal CM and targeted research, policy, and prevention efforts. Public health surveillance offers an opportunity to improve our understanding of the problem of CM. In 2006, the Centers for Disease Control and Prevention (CDC) funded state public health agencies in California, Michigan, and Oregon to implement a model approach for routine and sustainable CM surveillance and evaluated the experience of those efforts. OBJECTIVE We describe the experiences of 3 state health agencies in building collaborations and partnerships with multiple stakeholders for CM surveillance. DESIGN Qualitative, structured key informant interviews were carried out during site visits as part of an evaluation of a CDC-funded project to implement a model approach to CM surveillance. PARTICIPANTS Key informants included system stakeholders from state health agencies, law enforcement, child protective services, the medical community, and child welfare advocacy groups in the 3 funded states. RESULTS Factors that facilitated stakeholder engagement for CM surveillance included the following: streamlining and coordinating the work of Child Death Review Teams (CDRTs); demonstrating the value of surveillance to non-public health partners; codifying relationships with participating agencies; and securing the commitment of decision-makers. Legislative mandates were helpful in bringing key stakeholders together, but it was not sufficient to ensure sustained engagement. CONCLUSIONS The engagement process yielded multiple benefits for the stakeholders including a deeper appreciation of the complexity of defining CM; a greater understanding of risk factors for CM; and enhanced guidance for prevention and control efforts. States considering or currently undertaking CM surveillance can glean useful insights from the experiences of these 3 states and apply them to their own efforts to engage stakeholders.

Improving Identification of Child Maltreatment Fatalities Through Public Health Surveillance

Estimated fatalities due to child maltreatment may underestimate the true extent of fatal child maltreatment. Public health surveillance of child maltreatment fatalities can help identify previously undetected cases and inform research, policy, and prevention efforts. A pilot effort in three states offers potentially useful insights for state-level child welfare leaders considering a similar collaboration. Key findings include the added value of using multiple data sources to identify child maltreatment fatalities, the challenges and benefits of engaging multiple disciplines in the surveillance process, and the feasibility of incorporating a common definition of child maltreatment for surveillance purposes.
