"I was Confused About How to Take Care of Mom Because this Disease is Different Everyday": Vietnamese American Caregivers' Understanding of Alzheimer's Disease.

Family members provide the majority of caregiving to individuals living with Alzheimer's disease (AD) and related dementias. Asian American families are disproportionately impacted by the burden of caregiving due to limited knowledge about the disease in this community. This study explored how Vietnamese American caregivers understand AD and provide care to family members with AD. Twenty caregivers who have provided care to a family member with AD participated in a semi-structured qualitative interview. Data were analyzed using thematic analysis. Several themes were identified in the caregivers' understanding of AD: (a) "Now I know:" the disruptions, shocks and surprises leading up to the initial diagnosis; (b) The frustrations of managing family members' cognitive impairments; (c)"Going with the flow:" challenges in managing personality and behavioral changes; (d) The exhaustion of around-the-clock caregiving; (e)"Taking it day by day" in the face of progressively worsening symptoms. Underlining the participants' descriptions of AD was a shared understanding of the progressively worsening, complex and unpredictable nature of the disease that makes it challenging for family caregivers on a daily basis. Findings provide important implications for healthcare workers' outreach to Vietnamese American families to ease the caregiving experience through culturally-responsive education, thereby enhancing the families' ability to recognize the early symptoms and seek appropriate help.

Point-of-care ultrasound leads to diagnostic shifts in patients with undifferentiated hypotension.

OBJECTIVE: To assess the impact of an ultrasound hypotension protocol in identifying life-threatening diagnoses that were missed in the initial evaluation of patients with hypotension and shock. METHODS: A subset of cases from a previously published prospective study of hypotensive patients who presented at the Emergency Department in a single, academic tertiary care hospital is described. An ultrasound-trained emergency physician performed an ultrasound on each patient using a standardized hypotension protocol. In each case, the differential diagnosis and management plan was solicited from the treating physician immediately before and after the ultrasound. This is a case series of patients with missed diagnoses in whom ultrasound led to a dramatic shift in diagnosis and management by detecting life threatening pathologies. RESULTS: Following a published prospective study of the effect on an ultrasound protocol in 118 hypotensive patients, we identified a series of cases that ultrasound protocol unexpectedly determined serious life threatening diagnoses such as Takotsubo cardiomyopathy, pulmonary embolism, pericardial effusion with tamponade physiology, abdominal aortic aneurysm and perforated viscus resulting in proper diagnoses and management. These hypotensive patients had completely unsuspected but critical diagnoses explaining their hypotension, who in every case had their management altered to target the newly identified life-threatening condition. CONCLUSIONS: A hypotension protocol is an optimal use of ultrasound that exemplifies "right time, right place", and impacts decision-making at the bedside. In cases with undifferentiated hypotension, ultrasound is often the most readily available option to ensure that the most immediate life-threatening conditions are quickly identified and addressed in the order of their risk potential.
