Background: Child abuse is a significant issue across many countries. Despite the situation's innate understanding, many children are not reported to authorities and continue to experience abuse, sometimes even death. Healthcare professionals must be alert for abuse in any child who appears with injuries that are out of the ordinary because it is easy for indicators of child abuse to go unnoticed in a busy emergency department. The current study aims to evaluate and detect the challenges in diagnosing and reporting cases of child abuse among healthcare practitioners in emergency, pediatrics, and family medicine.Methods: A self-administered online disseminated questionnaire was used for data collection during the period from October 1 to December 30, 2022. A cross-sectional study was conducted on emergency, pediatrics, and family medicine healthcare practitioners working in hospitals in healthcare centers in Riyadh, Saudi Arabia. All data were collected, tabulated, and statistically analyzed using SPSS 23.0 for (IBM Corp., Armonk, NY) Windows.Results: The study sample constituted 200 physicians working in the front lines of healthcare like emergency, pediatrics, and family medicine primary care services, 50.5% were males and 49.5% were females. 36.5% of participants were 31-39 years old. 42% were family medicine physicians, 36.5% were pediatricians, and 21.5% were emergency medicine. About 43% of participants attended an educational workshop on child abuse. Nineteen percent of participants are very familiar with the diagnosis of child abuse and 36% of participants reported one to three cases of child abuse in the emergency department in the last year, 5% reported four to six cases and 56.5% reported none. Forty-seven percent of participants reported diagnosing one to five cases of child abuse throughout their whole career, 13% reported 11-15 cases, 6.5% reported six to 10 cases and 28.5% reported none. Causes of underdiagnosis of child abuse by healthcare providers were reported as 63% inexperience, 59% inadequate time for physical examination, 59% lack of diagnosis protocol, 51% lack of confidence in communicating with parents, 36% physicians' cultural background, and 38% lack of confidence in the diagnosis. 93.5% of participants think that healthcare practices need further education for child abuse.Conclusion: In conclusion, physicians in Saudi Arabia who participated in the study had good knowledge to diagnose a case of child abuse. Inexperience, inadequate time for physical examination, lack of diagnosis protocol, lack of confidence in communicating with parents, and physicians' cultural background were the main identified challenges for diagnosing child abuse. Familiarity with cases of child abuse was significantly associated with physicians’ age, specialty, and level of training.
