Pediatric Fingertip Injuries: Association With Child Abuse

PURPOSE: Pediatric fingertip injuries are most commonly reported in the setting of an accidental occurrence. The purpose of this study was to determine whether there is an association of child abuse and neglect with pediatric fingertip injuries. METHODS: The New York Statewide Planning and Research Cooperative System (2004 to 2013) administrative database was used to identify children aged 0 to 12 years who presented in the inpatient or outpatient (emergency department or ambulatory surgery) setting. International Classification of Diseases, Ninth Revision diagnosis codes were used to identify fingertip injuries (amputation, avulsion, or crushed finger) and abuse. Cohort demographics of children presenting with fingertip injuries were described. We analyzed the association between fingertip injuries and child abuse using multivariable logistic regression, with variables for insurance status, race, ethnicity, sex, and behavioral risks including depression, attention-deficit hyperactivity disorder, aggressive behavior, and autism. RESULTS: Of the 4,870,299 children aged 0 to 12 years in the cohort, 79,108 patients (1.62%) during the study period (2004 to 2013) presented with fingertip injuries. Of those with a fingertip injury, 0.27% (n = 216) presented either at that visit or in other visits with a code for child abuse, compared with 0.22% of pediatric patients without a fingertip injury (n = 10,483). In an adjusted analysis, the odds of a fingertip injury were 23% higher (odds ratio [OR] = 1.23; 95% confidence interval [CI], 1.07–1.41) for children who had been abused, compared with those who had not. Patients were more likely to present with fingertip injuries if they had ever had Medicaid insurance (OR = 1.40; 95% CI, 1.37–1.42) or had a behavioral risk factor (OR = 1.35; 95% CI, 1.30–1.40). CONCLUSIONS: Patients presenting with abuse are significantly more likely to have fingertip injuries during childhood compared with those without recorded abuse, which suggests that these injuries may be ones of abuse or neglect. Medicaid insurance, white race, and behavioral diagnoses of depression, attention-deficit hyperactivity disorder, aggressive behavior, and autism were also associated with increased odds of presenting with fingertip injuries. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic III.
