Intimate Partner Violence: A Primer for Radiologists to Make the "Invisible" Visible

[Blunt force trauma in forensic radiology]

OBJECTIVE

Description of the main forensic radiological examination modalities and findings in blunt force trauma in living and deceased adults.

METHODS

Elaboration of the essential points based on the authors' own experiences and relevant literature.

RESULTS AND CONCLUSION

Injury-related consequences of blunt force are frequently observed in forensic radiological diagnostics, especially in the context of accidents and suicides, and less frequently in homicides. The method of choice for radiological imaging of blunt force in deceased persons is native postmortem computed tomography (PMCT). In principle, the radiological effects of blunt force in PMCT do not differ significantly from those in living persons. Postmortem magnetic resonance imaging (PMMRI) is very suitable for imaging blunt soft tissue injuries in the shorter postmortem interval. In the case of living individuals with the consequences of blunt force trauma, imaging is primarily indicated for clinical diagnostic reasons. Common indications are domestic violence, violence against the elderly, and disputes in public spaces. The choice of radiological examination method depends on the clinical history and symptoms, and the radiological examinations can be subjected to a forensic assessment.

Understanding Health-Related Social Risks

Because of the established contribution of social factors to health outcomes, approaches that address upstream determinants of health have increasingly been recognized as cost-effective means to improve population health. Understanding and usage of precise terminology is important to facilitate collaboration across disciplines. Social determinants of health affect everyone, not just the socially and economically disadvantaged, whereas health-related social risks (HRSR) are specific adverse conditions at the individual or family level that are associated with poor health and related to the immediate challenges individuals face. Health-related social needs account for patient preference in addressing identified social risks. The use of validated screening tools is important to capture risk factors in a standardized fashion to support research and quality improvement. There is a paucity of studies that address HRSR in the context of radiology. This review provides an understanding of HRSR and outlines various ways in which radiologists can work to mitigate them.

Advancing research on femicide prevention: A mixed methods approach

Femicide, the killing of women, girls, and infants, is a pervasive problem affecting all global societies. Policy and research are impeded by inaccurate and missing prevalence data, gaps in understanding of femicide, especially for hard-to-reach marginalized populations, and conflicting perceptions between jurisdictions. Leveraging on a combined socio-ecologic model and Public Health approach, the paper spans the methods of a computed tomography-based injury study, an in-depth media-analysis, a legislation evaluation study, and a data barriers' study. Injury patterns, media depiction, and end-user consultations will close the loop on residual problems such as implementation, data gaps, and cultural perceptions. By mixed methods research representing multiple regions, and stakeholders, this project will enhance knowledge on interpersonal, institutional, and societal factors of femicide, advancing the humanitarian forensic discipline. The research method will identify emerging trends and facilitate improvements in tertiary prevention of femicide, specific to resource settings.

Orthopaedic Injury Patterns in Intimate Partner Violence: Defensive Wounds and Fracture Patterns: A Systematic Literature Review

BACKGROUND

Intimate partner violence (IPV) is a prevalent issue in the United States, despite universal screening measures for women of reproductive age. Orthopaedic surgeons have a unique opportunity to intervene in cases of IPV as musculoskeletal injuries, including fractures, are the second most common type of injury seen in IPV patients. This systematic literature review aims to identify patterns in musculoskeletal injuries caused by IPV to increase identification of patients afflicted by IPV.

METHODS

A comprehensive search of PubMed, PsycINFO, and Web of Science yielded 316 articles. Included were cohort studies and literature reviews of patients with an IPV-associated orthopaedic injury. Excluded were case studies, perspective articles, material predating 2003, and studies with pediatric or elderly populations. Sixteen articles met criteria.

RESULTS

Data supported historical findings that musculoskeletal injury is the second most common injury in patients with IPV, with upper extremity fractures prevailing. Minimally displaced phalanges fractures were most common (9.9%-64%), and isolated ulnar fractures had significant relative risk of IPV association (8.5-12.8). Patients with multiple fractures of varying chronicity were more likely to be victims of IPV (sensitivity 25.2%, specificity 99.2%, positive predictive value 96.2%), and these chronic fractures matched patterns of acute injury caused by IPV. New findings in male victims included a higher proportion of lower extremity and pelvic fractures seen in male cohorts.

CONCLUSION

This study synthesizes evidence of IPV-related orthopaedic injuries, offering objective criteria for identifying victims. Despite limitations in fracture descriptions, the findings aid various physicians in recognizing IPV victims. Considering ongoing IPV prevalence and screening challenges, further research on injury patterns is recommended.

Longitudinal visibility of MRI findings in living victims of strangulation

Initial experiences with magnetic resonance imaging (MRI) of living strangulation victims demonstrated additional findings of internal injuries compared to the standard clinical forensic examination. However, existing studies on the use of MRI for this purpose mostly focused on the first 48 h after the incident. The aims of this study were (a) to evaluate the longitudinal visibility of MRI findings after violence against the neck by performing two MRI examinations within 12 days and a minimum of four days between both MRI scans and (b) to assess which MRI sequences were most helpful for the detection of injuries. Twenty strangulation victims participated in this study and underwent one (n = 8) or two (n = 12) MRI scans. The first MRI examination was conducted during the first five days, the second five to 12 days after the incident. Two blinded radiologists assessed the MRI data and looked for lesions in the structures of the neck. In total, 140 findings were reported in the 32 MRI examinations. Most of the findings were detected in the thyroid and the muscles of the neck. T2-weighted SPACE with fat suppression, T1-weighted TSE and T1-weighted MPRAGE were rated as the most helpful MRI sequences. Subjects who showed findings in the initial scan also demonstrated comparable results in the second scan, which was performed on average 8.4 days after the incident. Our results show that even up to 12 days after the incident, the criminal proceeding of strangulation cases may greatly profit from the information provided by an MRI examination of the neck in addition to the standard clinical forensic examination.

Imaging of alert patients after non-self-inflicted strangulation: MRI is superior to CT

OBJECTIVE

To assess the accuracy of CT and MRI reports of alert patients presenting after non-self-inflicted strangulation (NSIS) and evaluate the appropriateness of these imaging modalities in NSIS.

MATERIAL AND METHODS

The study was a retrospective analysis of patient characteristics and strangulation details, with a comparison of original radiology reports (ORR) to expert read-outs (EXR) of CT and MRI studies of all NSIS cases seen from 2008 to 2020 at a single centre.

RESULTS

The study included 116 patients (71% women, p < .001, χ2), with an average age of 33.8 years, mostly presenting after manual strangulation (97%). Most had experienced intimate partner violence (74% of women, p < .001, χ2) or assault by unknown offender (88% of men, p < 0.002 χ2). Overall, 132 imaging studies (67 CT, 51% and 65 MRI, 49%) were reviewed. Potentially dangerous injuries were present in 7%, minor injuries in 22%, and no injuries in 71% of patients. Sensitivity and specificity of ORR were 78% and 97% for MRI and 30% and 98% for CT. Discrepancies between ORR and EXR occurred in 18% of all patients, or 62% of injured patients, with a substantial number of unreported injuries on CT.

CONCLUSIONS

The results indicate that MRI is more appropriate than CT for alert patients presenting after non-self-inflicted strangulation and underline the need for radiologists with specialist knowledge to report these cases in order to add value to both patient care and potential future medico-legal investigations.

CLINICAL RELEVANCE STATEMENT

MRI should be preferred over CT for the investigation of strangulation related injuries in alert patients because MRI has a higher accuracy than CT and does not expose this usually young patient population to ionizing radiation.

KEY POINTS

• Patients presenting after strangulation are often young women with a history of intimate partner violence while men typically present after assault by an unknown offender. • Expert read-outs of CT and MRI revealed potentially dangerous injuries in one of 14 patients. • MRI has a significantly higher sensitivity than CT and appears to be more appropriate for the diagnostic workup of alert patients after strangulation.

Assault-related anoxia and neck injuries in US emergency departments

BACKGROUND

Early identification of non-fatal strangulation in the context of intimate partner violence (IPV) is crucial due to its severe physical and psychological consequences for the individual experiencing it. This study investigates the under-reported and underestimated burden of IPV-related non-fatal strangulation by analysing assault-related injuries leading to anoxia and neck injuries.

METHODS

An IRB-exempt, retrospective review of prospectively collected data were performed using the National Electronic Injury Surveillance System All Injury Programme data from 2005 to 2019 for all assaults resulting in anoxia and neck injuries. The type and mechanism of assault injuries resulting in anoxia (excluding drowning, poisoning and aspiration), anatomical location of assault-related neck injuries and neck injury diagnosis by morphology, were analysed using statistical methods accounting for the weighted stratified nature of the data.

RESULTS

Out of a total of 24 493 518 assault-related injuries, 11.6% (N=2 842 862) resulted from IPV (defined as perpetrators being spouses/partners). Among 22 764 cases of assault-related anoxia, IPV accounted for 40.4%. Inhalation and suffocation were the dominant mechanisms (60.8%) of anoxia, with IPV contributing to 41.9% of such cases. Neck injuries represented only 3.0% of all assault-related injuries, with IPV accounting for 21% of all neck injuries and 31.9% of neck contusions.

CONCLUSIONS

The study reveals a significant burden of IPV-related anoxia and neck injuries, highlighting the importance of recognising IPV-related strangulation. Comprehensive screening for IPV should be conducted in patients with unexplained neck injuries, and all IPV patients should be screened for strangulation events.

Imaging of Intimate Partner Violence, From the AJR Special Series on Emergency Radiology

Intimate partner violence (IPV) is a highly prevalent public health issue with multiple adverse health effects. Radiologists are well suited to assessing a patient's likelihood of IPV. Recognition of common IPV injury mechanisms and resulting target and defensive injury patterns on imaging and understanding of differences between patients who have experienced IPV and those who have not with respect to use of imaging will aid radiologists in accurate IPV diagnosis. Target injuries often involve the face and neck as a result of blunt trauma or strangulation; defensive injuries often involve an extremity. Awareness of differences in injury patterns resulting from IPV-related and accidental trauma can aid radiologists in detecting a mismatch between the provided clinical history and imaging findings to support suspicion of IPV. Radiologists should consider all available current and prior imaging in assessing the likelihood of IPV; this process may be aided by machine learning methods. Even if correctly suspecting IPV on the basis of imaging, radiologists face challenges in acting on that suspicion, including appropriately documenting the findings, without compromising the patient's confidentiality and safety. However, through a multidisciplinary approach with appropriate support mechanisms, radiologists may serve as effective frontline physicians for raising suspicion of IPV.

Intimate Partner Violence in the Orthopaedic Patient Population: What Surgeons Need to Know

»

Intimate partner violence (IPV) is under-reported and pervasive in the orthopaedic surgical setting.

»

Screening programs that could increase reporting and assist in treatment and prevention are commonly underutilized.

»

There is little formalized education during orthopaedic surgery training for IPV.

»

The incidence of IPV continues to increase in the setting of recent stressors, such as COVID-19, and the orthopaedic surgeon should play a role in the screening and identification of patients presenting with IPV injuries and provide resources and referral.

Imaging and Non-imaging Findings of Intimate Partner Violence on the Trauma Service: A Retrospective Analysis of Two Level 1 Trauma Centers

RATIONALE AND OBJECTIVES

Intimate partner violence (IPV) is a serious public health issue. This study aims to characterize IPV-related injuries in trauma patients presenting to emergency departments (ED) who required hospitalization.

MATERIALS AND METHODS

Trauma registries of two Level 1 trauma centers were searched for assault-related ED visits by adults reporting "abuse" over 3 and 5 years to identify IPV victims. Imaging and electronic medical records were reviewed for demographics, injury type, hospital stay, and previous or subsequent presentations for presumed IPV.

RESULTS

Twenty-nine of 18,465 (0.2%) individuals seen on the trauma service had reported IPV. Majority were women (90%, mean age 37) and Caucasian (69%), over 50% had psychiatric or substance use comorbidities, and 45% reported prior IPV. Blunt trauma (22/29) was more common than penetrating trauma. Soft tissue injuries dominated when including both radiologic and non-radiologic findings. Excluding two patients who were not imaged, most frequent injuries identified on imaging were to the head/face (14/27), followed by the chest (9/27; mainly rib fractures), upper extremity and abdomen (7/27 each). All spinal fractures involved the upper lumbar spine. Synchronous injuries to multiple body regions were common, particularly craniofacial and upper extremity. Twenty-eight of 29 patients scored a grade 3-4 on the IPV severity grading scale. Eight (28%) patients required intensive care unit -level care. One patient passed. Four (14%) patients had prior IPV-related ED presentations.

CONCLUSION

While craniofacial and soft tissue injuries dominate, IPV can also result in serious thoracoabdominal, extremity and spinal injuries, even death. Multisystem injuries are common with synchronous craniofacial and upper extremity injuries being the most common combination.

Imaging patterns of thoracic injuries in survivors of intimate partner violence (IPV)

PURPOSE

To recognize the imaging patterns of thoracic injuries in survivors of intimate partner violence (IPV).

MATERIALS AND METHODS

A retrospective radiological review of 688 patients self-reporting IPV to our institution's violence intervention and prevention program between January 2013 and June 2018 identified 30 patients with 89 thoracic injuries. Imaging and demographic data were collected.

RESULTS

Thirty survivors with 89 injuries to the thorax were identified with a median age of 43.5 years (21-65 years). IPV was reported or disclosed as the direct cause of injury in 50% (15/30) of survivors, including all nine patients who sustained penetrating injuries. The most common injury type was fracture (72%, 64/89) with 52 rib, 3 sternal, 2 clavicular, and 7 vertebral fractures. There were 3 acromioclavicular dislocations. Among rib fractures, right lower anterior rib fractures (9-12 ribs) were the most common(30%, 16/52). There were 10 superficial soft tissue injuries. There were 12 deep tissue injuries which included 2 lung contusions, 2 pneumomediastinum, 7 pneumothoraces, 1 hemothorax. One third of patients had concomitant injuries of other organ systems, most commonly to the head and face, followed by extremities and one third of patients had metachronous injuries.

CONCLUSION

Acute rib fractures with concomitant injuries to the head, neck, face, and extremities with an unclear mechanism of injury should prompt the radiologist to discuss the possibility of IPV with the ordering physician.

ADVANCES IN KNOWLEDGE

Recognizing common injuries to the thorax will prompt the radiologists to suspect IPV and discuss it with the clinicians.

Facial injury patterns in victims of intimate partner violence

Purpose

To evaluate the imaging findings of facial injuries in patients reporting intimate partner violence (IPV).

Methods

A retrospective review of radiology studies performed for 668 patients reporting IPV to our institution’s violence prevention support program identified 96 patients with 152 facial injuries. Demographics, imaging findings, and clinical data obtained from a review of the electronic medical records (EMR) were analyzed to categorize injury patterns.

Results

The study cohort consisted of 93 women and 3 men with a mean age of 35 years (range 19–76; median 32). At the time of presentation, 57 (59.3%) patients reported IPV as the mechanism of injury. The most frequent site of injury was the midface, seen in 65 (67.7%) patients. The most common fracture sites were the nasal bones (45/152, 29.6%), followed by the mandible (17/152, 11.1%), and orbits (16/152, 10.5%). Left-sided injuries were more common (90/152; 59.2%). A vast majority of fractures (94.5%) showed minimal or no displacement. Over one-third of injuries (60/152, 39.4%) demonstrated only soft tissue swelling or hematoma without fracture. Associated injuries were seen most frequently in the upper extremity, occurring synchronously in 11 (11.4%) patients, and preceding the index facial injury in 20 (21%) patients.

Conclusion

/advances in knowledge.

The midface was the most frequent location of injury in victims of intimate partner violence, and the nasal bone was the most commonly fractured facial bone. Recognizing these injury patterns can help radiologists suspect IPV and prompt them to discuss the possibility of IPV with the clinical providers.

Upper extremity fractures due to intimate partner violence versus accidental causes

PURPOSE

The purpose of this study is to evaluate the prevalence of intimate partner violence (IPV)-related upper extremity fractures (UEF) in women presenting to US emergency departments (ED) and compare their anatomic location to those due to accidental falls or strikes.

METHODS

An Institutional Review Board exempt, retrospective review of prospectively collected data was performed using the National Electronic Injury Surveillance System's All Injury Program data from 2005 through 2015 for all UEF sustained in women 15 to 54 years old. Injuries based on reported IPV versus accidental falls or strikes were analyzed accounting for the weighted, stratified nature of the data.

RESULTS

IPV-related UEF represented 1.7% of all UEF and 27.2% of all IPV fractures. The finger was the most common fracture site in IPV (34.3%) and accidental striking (53.3%) but accounted for only 10% of fall-related UEF. There was a higher proportion of shoulder fractures in IPV (9.2%) compared to accidental falls (7.4%) or strikes (2.9%). The odds of a finger fracture were 4.32 times greater in IPV than falling and of a shoulder fracture were 3.65 greater in IPV than accidental striking (p < 0.0001).

CONCLUSIONS

While the finger is the most common site for IPV UEF, it is also the most common location for accidental striking. A lower proportion of finger fractures in fall and of shoulder/forearm fractures in accidental striking should prompt the radiologist to discuss the possibility of IPV with the ED physician in any woman presenting with a finger fracture due to fall and a shoulder/forearm fracture with a vague history of accidental striking.

"If Their Face Starts Turning Purple, You Are Probably Doing Something Wrong": Young Men's Experiences with Choking During Sex

Choking/strangulation during sex has become prevalent in the United States. Yet, no qualitative research has addressed men's choking experiences. Through interviews with 21 young adult men, we examined the language men use to refer to choking, how they first learned about it, their experiences with choking, and consent and safety practices. Men learned about choking during adolescence from pornography, partners, friends, and mainstream media. They engaged in choking to be kinky, adventurous, and to please partners. While many enjoyed or felt neutral about choking, others were reluctant to choke or be choked. Safety and verbal/non-verbal consent practices varied widely.

Longitudinal imaging history in early identification of intimate partner violence

OBJECTIVES

To describe the imaging findings of intimate partner violence (IPV)-related injury and to evaluate the role of longitudinal imaging review in detecting IPV.

METHODS

Radiology studies were reviewed in chronological order and IPV-related injuries were recorded among 400 victims of any type of abuse (group 1) and 288 of physical abuse (group 2) from January 2013 to June 2018. The likelihood of IPV was assessed as low/moderate/high based on the review of (1) current and prior anatomically related studies only and (2) longitudinal imaging history consisting of all prior studies. The first radiological study date with moderate/high suspicion was compared to the self-reported date by the victim.

RESULTS

A total of 135 victims (33.8%) in group 1 and 144 victims (50%) in group 2 demonstrated IPV-related injuries. Musculoskeletal injury was most common (58.2% and 44.5% in groups 1 and 2, respectively; most commonly lower/upper extremity fractures), followed by neurologic injury (20.9% and 32.9% in groups 1 and 2, respectively; most commonly facial injury). With longitudinal imaging history, radiologists were able to identify IPV in 31% of group 1 and 46.5% of group 2 patients. Amongst these patients, earlier identification by radiologists was provided compared to the self-reported date in 62.3% of group 1 (median, 64 months) and in 52.6% of group 2 (median, 69.3 months).

CONCLUSIONS

Musculoskeletal and neurological injuries were the most common IPV-related injuries. Knowledge of common injuries and longitudinal imaging history may help IPV identification when victims are not forthcoming.

KEY POINTS

• Musculoskeletal injuries were the most common type of IPV-related injury, followed by neurological injuries. • With longitudinal imaging history, radiologists were able to better raise the suspicion of IPV compared to the selective review of anatomically related studies only. • With longitudinal imaging history, radiologists were able to identify IPV earlier than the self-reported date by a median of 64 months in any type of abuse, and a median of 69.3 months in physical abuse.

Artificial Intelligence Enabling Radiology Reporting

The radiology reporting process is beginning to incorporate structured, semantically labeled data. Tools based on artificial intelligence technologies using a structured reporting context can assist with internal report consistency and longitudinal tracking. To-do lists of relevant issues could be assembled by artificial intelligence tools, incorporating components of the patient's history. Radiologists will review and select artificial intelligence-generated and other data to be transmitted to the electronic health record and generate feedback for ongoing improvement of artificial intelligence tools. These technologies should make reports more valuable by making reports more accessible and better able to integrate into care pathways.

Intimate Partner Violence and the Role of Breast Imaging Centers

Intimate partner violence (IPV) is defined as physical violence, sexual violence, stalking, or psychological harm by a current or former intimate partner. In the United States, one in three women will experience a form of IPV in their lifetime. Screening for IPV at breast imaging centers provides an important opportunity to identify and assist affected women. Breast imaging centers provide a private environment where passive and active IPV screening methods can be employed. In addition, when obtaining a mammogram or breast ultrasound, the patient's upper chest is exposed, which could demonstrate patterns of abuse. This article discusses the need for IPV screening, via both passive and active methods, and implementation steps for breast imaging centers.

Recognizing Isolated Ulnar Fractures as Potential Markers for Intimate Partner Violence

PURPOSE

This study aimed to assess the incidence of intimate partner violence (IPV) in women with isolated ulnar fractures and compare the injury characteristics in victims of IPV with those who sustained the same fractures due to other causes.

METHODS

Electronic health records from three level I trauma centers were queried to identify a cohort of women, aged 18 to 50, sustaining isolated ulnar fractures from 2005 to 2019. Radiographs were reviewed for fracture location, comminution, and displacement. Demographic data, number of visits to the emergency department, and documentation of IPV were also collected. Patients were stratified into four groups based on clinical chart review: confirmed IPV, possible IPV, not suspected for IPV, and not IPV. Historical imaging analysis for IPV prediction was also performed.

RESULTS

There were 62 patients, with a mean age of 31 years (IPV: 12 confirmed, 8 possible, 8 suspected not IPV, 34 confirmed not IPV). Comparative analysis with and without suspected cases demonstrated IPV to be associated with nondisplaced fractures (95% versus 43%; P < .001 and 91% versus 44%; P = .012). Confirmed cases were also associated with homelessness (46% versus 0%; P < .001), and the number of documented emergency department visits (median 7.0; interquartile range 2.0-12.8 versus 1.0; interquartile range 1.0-2.0; P < .001). Formal documentation of IPV evaluation was completed in only 14 of 62 (22.5%) patients. Historical imaging analysis predicted IPV in 8 of 12 (75%) confirmed IPV cases.

CONCLUSION

Up to one-third of adult women sustaining isolated ulnar fractures may be the victims of IPV. Lack of displacement on radiographs, frequent emergency department visits, and homelessness would favor IPV etiology.

Imaging patterns of lower extremity injuries in victims of intimate partner violence (IPV)

PURPOSE

To describe the pattern and distribution of lower extremity injuries in victims of intimate partner violence (IPV).

MATERIALS AND METHODS

A retrospective radiological review of 688 patients reporting IPV to our institution's violence intervention and prevention program between January 2013 and June 2018 identified 88 patients with 154 lower extremity injuries. All lower extremity injuries visible on radiological studies were analyzed. Concomitant, recurrent, and associated injuries were also collected, in addition to the demographic data.

RESULTS

The injuries consisted of 103 fractures, 46 soft tissue injuries, and 5 dislocations. The foot was the most common site of injury representing 39% (60/154) of total injuries, 48% (49/103) of fractures, 17% (8/46) of soft tissue injuries, and 3 dislocations. The ankle was the second most common site of injury representing 30% (47/154) of total injuries, 20% (21/103) of fractures, and 57% (26/46) of soft tissue injuries. Recurrent injuries of the lower extremity were seen in 30% (26/88) of victims who had 74 recurrent injuries. The most common sites of recurrent injury were the foot and ankle, representing 72% (53/74) of recurrent injuries.

CONCLUSION

Recurrent injuries of the foot and ankle, synchronous craniofacial injuries, and upper extremity injuries in young women (<35 years) should prompt radiologists to consider IPV.
