Prevalence and predictors of elder abuse among older adults attending emergency departments: a prospective cohort study

INTRODUCTION

Elder abuse is associated with impaired physical and psychological health. It is, however, rarely identified in emergency departments (EDs). The objective was to determine the prevalence and the predictors of elder abuse among older adults visiting EDs.

METHODS

This prospective cohort study was conducted in eight Canadian EDs between May and August 2021. Patients were eligible if they were ≥ 65 years old, oriented to time, and with a Canadian Triage and Acuity Scale score 3, 4 or 5. In a private setting, participants were questioned directly about abuse as part of a larger questionnaire exploring ten non-medical problems. We used multivariable logistic regression to identify predictors of elder abuse.

RESULTS

A total of 1061 participants were recruited (mean age: 77.1 (SD 7.6) years, female sex: 55.7%, lived alone: 42.5%). Patients mostly attended EDs for pain (19.6%), neurologic (11.3%) or cardiovascular (8.4%) symptoms. The most frequent pre-existing comorbidities were hypertension (67.2%), mental health conditions (33.3%) and cardiac insufficiency (29.6%). Mobility issues outside (41.0%) or inside their home (30.7%) and loneliness (29.4%) were also frequent. Fifty-four (5.1%) participants reported elder abuse, of which 34.3% were aware of available community-based resources. Identified predictors of elder abuse were female sex (OR 2.8 [95%CI 1.4; 5.6]), financial difficulties (OR 3.6 [95%CI 1.8; 7.3]), food insecurity (OR 2.7 [95%CI 1.2; 5.6]), need for a caregiver (OR 2.7 [95%CI 1.5; 5.0]) and at least one pre-existing mental health condition (OR 2.6 [95%CI 1.4; 4.9]).

CONCLUSION

When questioned directly, 5.1% of older adults attending EDs reported experiencing abuse. Female sex, functional impairment, social vulnerability, and mental health comorbidities are associated with elder abuse. Given its importance and relatively high prevalence, ED professionals should have a low threshold to ask directly about elder abuse.

Prehospital Use of the Esophageal Tracheal Combitube Supraglottic Airway Device: A Retrospective Cohort Study

BACKGROUND

In the province of Quebec (Canada), paramedics use the esophageal tracheal Combitube (ETC) for prehospital airway management.

OBJECTIVES

Our main objective was to determine the proportion of patients with successful ventilation achieved after ETC use. Our secondary aim was to determine the number of ETC insertion attempts required to ventilate the patient.

METHOD

This is a retrospective cohort study. All patients who had ≥1 attempt to insert an ETC during prehospital care between January 1, 2017 and December 31, 2018 were included. Prehospital and in-hospital data were extracted. Successful ventilation was defined as thorax elevation, lung sounds on chest auscultation, or positive end-tidal capnography after ETC insertion.

RESULTS

A total of 580 emergency medical services interventions (99.3% cardiac arrests) were included. Most patients were men (62.5%) with a mean age 67.0 years (SD 17.6 years), and 35 (13.1%) of the 298 patients transported to emergency department survived to hospital discharge. Sufficient information to determine whether ventilation was successful or not was available for 515 interventions. Ventilation was achieved during 427 (82.7%) of these interventions. The number of ETC insertion attempts was available for 349 of the 427 successful ETC use. Overall, the first insertion resulted in successful ventilation during 294 interventions for an overall proportion of first-pass success ranging between 57.1% and 72.1%.

CONCLUSION

Proportions of successful ventilation and ETC first-pass success are lower than those reported in the literature with supraglottic airway devices. The reasons explaining these lower rates and their impact on patient-centered outcomes need to be studied.

Effect of glycosaminoglycans and enzymes on the integrity of human placental amnion as a barrier to cell invasion

The effects of glycosaminoglycans and several enzymes on the integrity of the human placental amnion and the consequent effects on the permeability of this structure to virally transformed cells and their parent line were examined. Treatment of the amnion with hyaluronate, heparin, and chondroitin ABC lyase affected the structure of both the epithelium and the extracellular matrix and resulted in a significant increase in tumor cell invasion, but it had no significant effect on the invasion of the parent cell line. These polymers promoted the disorganization of the epithelial cell layer, and their presence resulted both in the matting of collagen fibrils in the stroma and in the loosening of the basement membrane. Pronase treatment removed epithelial cells and stripped collagen fibrils of granules, but it did not promote tumor or parent cell invasion, perhaps as a result of loss of attachment factors. Chondroitin sulfate did not affect the epithelial structure or the rate of tumor invasion and had only slight effects on the structure of the basement membrane and the stroma. These results are consistent with the thesis that the continuity of epithelium is critical to resisting tumor cell invasion and suggest that glycosaminoglycans, in addition to certain enzymes, can alter this integrity.
