Patient will present as → a 52-year-old man is brought to the emergency department by a neighbor after being found with bruises on his arms, a swollen jaw, and superficial abrasions on his chest and back. He appears hesitant to speak and states he "fell down the stairs." On further questioning in a private setting, he discloses that his adult sibling, who is also his caregiver, has pushed, hit, and thrown objects at him during arguments. He reports feeling fearful, and that he is not allowed to leave the house unaccompanied. The clinical team suspects adult physical abuse by a nonpartner and initiates protective services involvement.
Key Points:
Adult physical abuse refers to intentional acts of physical force by another adult (excluding intimate partners) that cause or have the potential to cause physical injury or psychological harm
- Perpetrators may include caregivers, adult children, roommates, relatives, or institutional staff
- Physical abuse includes hitting, slapping, pushing, scratching, biting, punching, throwing objects, or any action likely to result in injury or instill significant fear
- Victims may present with inconsistent injury explanations, delays in seeking care, multiple injuries in various stages of healing, or psychological symptoms such as anxiety, hypervigilance, or withdrawal
- Complications of abuse can include chronic pain, disability, depression, PTSD, and increased risk of future abuse or death
DSM-5 Diagnostic Criteria
According to the DSM-5, adult physical abuse by a nonspouse or nonpartner is categorized under "Adult Maltreatment" and includes the following criteria:
- Nonaccidental physical acts such as pushing, shoving, scratching, slapping, throwing objects, punching, or biting
- The acts have resulted in or have reasonable potential to result in physical harm or have caused significant fear
- Verbal or symbolic acts may accompany physical abuse and contribute to psychological harm (e.g., berating, humiliating, isolating, or threatening)
- Obstruction of access to resources, restriction of movement, or intimidation may also be present
- The perpetrator is not an intimate partner, differentiating it from intimate partner violence
- Acts intended for self-defense or protection of others are excluded from this diagnosis
Adult Physical Abuse vs. Intimate Partner Violence (IPV)
While both involve abuse of adults, there are key differences between adult physical abuse by a nonpartner and intimate partner violence:
- Adult physical abuse (nonpartner) involves non-spousal perpetrators such as family members, caregivers, or acquaintances, while IPV involves a current or former romantic or sexual partner
- IPV often includes a cyclical pattern of tension, violence, and reconciliation, whereas nonpartner abuse may occur in a more sporadic or caregiver-dependent dynamic
- Legal and protective resources, including mandatory reporting, may differ based on relationship to the abuser and setting of the abuse (e.g., home vs. institution)

- Ensure immediate safety by removing the patient from the abusive environment if needed
- Treat physical injuries: Address wounds, fractures, and pain; evaluate for internal injuries
- Provide emotional support: Connect the patient with mental health resources, social work, and support groups
- Coordinate care with an interprofessional team including physicians, social workers, case managers, and law enforcement when appropriate
- Educate the patient about their rights and available protective services and assist with safety planning
Question 1 |
A 38-year-old man is brought to the emergency department by police after being found disoriented on the street. He has multiple contusions on his face and torso, a laceration above his right eye, and complains of rib pain. He is homeless and has a history of schizophrenia, for which he inconsistently takes medication. He reports being "jumped by a group of guys" near the shelter where he sometimes stays, who he states were trying to take his backpack. He mentions this has happened before with different people. Which of the following factors most significantly increases this individual's vulnerability to experiencing recurrent physical assault by unrelated perpetrators in the community?
His history of schizophrenia Hint: While severe mental illness can make individuals more vulnerable in various ways (e.g., impaired reality testing, difficulty communicating needs), it's the consequence of how society and his environment interact with his illness (like homelessness) that often directly leads to increased assault risk from unrelated perpetrators. | |
His inconsistent medication adherence Hint: Similar to the history of schizophrenia, poor medication adherence can worsen psychiatric symptoms and impair functioning, indirectly increasing vulnerability. However, the environmental exposure due to homelessness is a more direct risk factor for street violence. | |
His age and gender Hint: While young males are generally at higher risk for certain types of community violence, in the context of multiple vulnerabilities, age and gender alone are less significant than his homeless status for recurrent victimization by unrelated perpetrators. | |
His homelessness and social isolation | |
His previous experiences of being assaulted Hint: While a history of victimization is a predictor of future victimization, it's more of an outcome of underlying vulnerabilitiesWhile a history of victimization is a predictor of future victimization, it's more of an outcome of underlying vulnerabilities than the primary risk factor itself. His homelessness and social isolation are the conditions that likely led to both past and present assaults. than the primary risk factor itself. His homelessness and social isolation are the conditions that likely led to both past and present assaults. |
Question 1 Explanation:
While several factors contribute to this man's vulnerability, homelessness and the associated social isolation most significantly increase his risk of experiencing recurrent physical assault by unrelated perpetrators. Individuals experiencing homelessness are often forced to live in unsafe environments with limited protection, making them easier targets for opportunistic violence. Social isolation further exacerbates this risk, as there may be fewer witnesses to assaults and fewer support systems to help the individual escape dangerous situations or report abuse. His mental illness and inconsistent medication use can compound this vulnerability by impairing his judgment, ability to protect himself, or navigate social services, but the immediate environmental and social context of homelessness is a primary driver of exposure to community violence from unrelated individuals.
Question 2 |
A 29-year-old woman presents to your clinic with a chief complaint of "arm pain." She is accompanied by her older brother, who appears very concerned and explains that his sister has a developmental disability and lives with him as her primary caregiver. He states she "fell out of her chair" two days ago. On examination, the patient is non-verbal but makes eye contact and appears to understand simple commands. You note significant ecchymosis and swelling over her left proximal humerus. She winces and withdraws her arm when you attempt to palpate the area. You also observe several well-demarcated, loop-shaped bruises on her back that appear to be in different stages of healing. The brother explains these are "from her thrashing during seizures," though he cannot recall when her last seizure occurred. An X-ray confirms an acute, displaced spiral fracture of the left humerus. What is the most appropriate immediate next step in your assessment?
Ask the brother to provide a more detailed history of the patient's seizure activity Hint: While gathering more history is important, relying solely on the caregiver's account when abuse is suspected is insufficient and may perpetuate a misleading narrative. The patient's direct input, if obtainable, is critical. | |
Administer pain medication and splint the arm Hint: While providing medical care for the fracture is essential and should be done concurrently or immediately after the private interview, it is not the next step in assessing for abuse. Safety assessment is equally urgent. | |
Document the injuries meticulously with photographs and detailed descriptions Hint: Excellent documentation is absolutely critical in cases of suspected abuse. However, it is something that should be done throughout the encounter. The immediate next step to further the assessment of potential abuse is to attempt to speak with the patient alone. | |
Perform a full skeletal survey to screen for other fractures Hint: A skeletal survey may be indicated if abuse is confirmed or highly suspected to look for other, older injuries, particularly in non-verbal or vulnerable individuals. However, attempting a private interview to gather more immediate information regarding the current situation and safety is a higher priority next assessment step before ordering extensive imaging beyond what's needed for the acute fracture. | |
Separate the patient from her brother to attempt a private interview, using communication aids if necessary |
Question 2 Explanation:
The patient presents with a spiral fracture of the humerus (often associated with a twisting mechanism and suspicious for non-accidental injury in a non-ambulatory or dependent individual), multiple patterned bruises of varying ages (loop-shaped marks are highly concerning for an inflicted injury with an object), and a caregiver's explanation that seems inconsistent with some of the findings (seizures don't typically cause loop-shaped bruises). Given her vulnerability due to a developmental disability and reliance on her brother for care, the suspicion for physical abuse by the caregiver must be high. The most appropriate immediate next step in assessment is to separate the patient from her brother to attempt a private interview, using communication aids if necessary. This allows for an opportunity to assess the patient's perspective, observe her demeanor without the caregiver present, and attempt to elicit information about her injuries and her safety, even with communication challenges. This step is crucial for gathering information directly from the potential victim before making further decisions about reporting or intervention.
Question 3 |
A 40-year-old man with a chronic pain syndrome and opioid use disorder is brought to the emergency department by ambulance after an apparent overdose. He is now alert and oriented after receiving naloxone. During your evaluation, he tearfully discloses that his roommate, who provides him with housing in exchange for his disability checks, has been physically assaulting him and withholding his pain medication to control him. He shows you multiple bruises on his arms and chest, which he states are from his roommate hitting him. He expresses extreme fear of returning to the apartment and states he has nowhere else to go. He is medically stable for discharge from an overdose perspective. What is the most appropriate and legally mandated next step for the healthcare provider in this situation in most US jurisdictions?
Offer the patient a referral to a substance abuse treatment program Hint: While addressing his opioid use disorder is important for his long-term health, it does not address the acute issue of physical abuse and his immediate safety. This can be part of a comprehensive plan but not the most appropriate and legally mandated next step in this context. | |
Prescribe a different pain medication regimen that is less prone to diversion Hint: While medication management is relevant, his current regimen is being withheld abusively. The primary issue is the abuse and safety, not just the specifics of his pain medication. | |
Provide the patient with information on local homeless shelters and discharge him Hint: Simply providing information on shelters without making a formal report to APS and actively engaging in safe discharge planning is insufficient for a vulnerable adult disclosing abuse. He needs more active intervention and support. | |
Report the suspected abuse and the patient's disclosure to Adult Protective Services (APS) and facilitate a safe discharge plan | |
Contact the roommate to mediate a safety agreement before the patient returns home Hint: It could escalate the abuse, alert the abuser to the disclosure, and further endanger the patient. Mediation is not appropriate in situations of clear abuse and power imbalance. |
Question 3 Explanation:
This patient is a vulnerable adult (due to chronic pain, opioid use disorder, and dependence on his roommate for housing and potentially finances) who has made a direct disclosure of physical abuse and exploitation by his caregiver/roommate. He also expresses fear of returning to the abusive environment. In most US jurisdictions, healthcare providers are mandated reporters for suspected abuse of vulnerable adults. Therefore, the most appropriate and legally mandated next step is to report the suspected abuse and the patient's disclosure to Adult Protective Services (APS) and work with social services to facilitate a safe discharge plan. A safe discharge plan is critical and may involve coordinating with APS for temporary housing, connecting him with victim advocacy services, and ensuring he does not return to the abusive situation without protective measures in place. His immediate safety from further abuse takes precedence.
