Development of an acute medical unit to optimize patient flow and early discharges in a tertiary care hospital in the United Arab Emirates.

BACKGROUND: Hospitals worldwide are seeing an increased number of acute admissions, with resultant emergency department (ED) crowding and increased length of stay (LOS). Acute Medical Units (AMUs) have developed throughout the United Kingdom and other Western countries to reduce the burden on EDs and improve patient flow. Limited information is available on AMUs in the Middle East. The purpose of this study is to describe the development of the first AMU in the United Arab Emirates (UAE) for general medical patients and its impact on LOS, early discharges, ED boarders, and readmission rates. METHODS: We established a consultant-led AMU in a tertiary hospital in the UAE. A retrospective comparative review of all general medical admissions to the AMU between August 1, 2020 and December 31, 2020 and all admissions to the traditional medical wards between August 1, 2019 and December 31, 2019 was conducted. RESULTS: The average LOS reduced from 10 to 5 days (95% CI [4.14-6.25], p < 0.001) after the introduction of AMU. Early discharges increased by 22%. The number of outliers and number of patients boarding in ED reduced significantly (111 in 2019 vs. 60 in 2020, p < 0.05; 938 in 2019 vs. 104 in 2020, p < 0.001 respectively), with a decrease in ED waiting time from 394 min to 134 min (95% CI [229.25-290.75], p < 0.001). There was no increase in 30-day readmission rates. CONCLUSION: Restructuring the system of care can reduce LOS, overcome discharge barriers and improve patient flow. Similar units can be developed in hospitals throughout the UAE and the region to reduce LOS and improve patient flow through acute care units.

The Impact of an Acute Medical Unit in Internal Medicine on Resident Education.

Background: Medical trainees are expected to provide care for increasingly sick and treatment intensive patients. To improve patient care, hospitals worldwide have developed acute medical units (AMUs), dedicated medical wards that provide care for patients during the first 24 to 72 hours of an emergency medical hospital admission. A distinguishing feature of these units is that they are supervised by senior clinicians and offer multidisciplinary patient-centered care. Little is known about the impact of AMUs on trainee supervision and education. Methods: In this educational case study, we describe the evolution, process and structure of our AMU service. We also provide resident and teaching faculty perceptions of the impact of this intervention on education and supervision. Results: Questionnaire results showed that residents and teaching attendings believed that supervision and education were improved on the AMU, as compared to the traditional medical ward model. Residents also felt that their knowledge and clinical skills in managing acute patients improved. Procedure skills were less impacted by the intervention. A small number of residents believed that the AMU model worsened supervision and education. Conclusion: Integrating medical trainees into an AMU allowed for early evaluation and input from senior clinicians and increased opportunities to work in and learn from multidisciplinary teams, contributing to improved resident supervision and education. Future studies are needed to assess the long-term impact of the AMU on educational outcomes.

Effectiveness of BBIBP-CorV vaccine against severe outcomes of COVID-19 in Abu Dhabi, United Arab Emirates.

The effectiveness of the inactivated BBIBP-CorV vaccine against severe COVID-19 outcomes (hospitalization, critical care admission and death due to COVID-19) and its long-term effectiveness have not been well characterized among the general population. We conducted a retrospective cohort study using electronic health records of 3,147,869 adults, of which 1,099,886 vaccinated individuals were matched, in a 1:1 ratio to 1,099,886 unvaccinated persons. A Cox-proportional hazard model with time varying coefficients was used to assess the vaccine effectiveness adjusting for age, sex, comorbidity, ethnicity, and the calendar month of entry into the study. Our analysis showed that the effectiveness was 79.6% (95% CI, 77.7 to 81.3) against hospitalization, 86% (95% CI, 82.2 to 89.0) against critical care admission, and 84.1% (95% CI, 70.8 to 91.3) against death due to COVID-19. The effectiveness against these severe outcomes declined over time indicating the need for booster doses to increase protection against severe COVID-19 outcomes.

Post-infectious and post-acute sequelae of critically ill adults with COVID-19.

BACKGROUND: Data on the post-acute and post-infectious complications of patients who have recovered from severe coronavirus disease 2019 (COVID-19) are limited. While studies report that approximately 5-15% of COVID-19 hospitalized patients require intensive care and mechanical ventilation, a substantially higher number need non-invasive ventilation and are subject to prolonged hospitalizations, with long periods of immobility and isolation. The purpose of this study is to describe the post-infectious sequelae of severe viral illness and the post-acute complications of intensive care treatments in critically ill patients who have recovered from severe COVID-19 infection. METHODS: We performed a retrospective chart review of adult patients initially hospitalized with confirmed COVID-19 infection, who recovered and were transferred to a general medical ward or discharged home between March 15, 2020 and May 15, 2020, dates inclusive, after an intensive care unit (ICU) or high dependency unit (HDU) admission in a designated COVID-19 hospital in the United Arab Emirates. Demographic data, underlying comorbidities, treatment, complications, and outcomes were collected. Descriptive statistical analyses were performed. RESULTS: Of 71 patients transferred out of ICU (n = 38, 54%) and HDU (n = 33, 46%), mean age was 48 years (SD, 9.95); 96% men; 54% under age 50. Mean ICU stay was 12.4 days (SD, 5.29), HDU stay was 13.4 days (SD, 4.53). Pre-existing conditions were not significantly associated with developing post-acute complications (Odds Ratio [OR] 1.1, 95% confidence interval [CI] 0.41, 2.93, p = 1.00). Fifty nine percent of patients had complications; myopathy, swallowing impairments, and pressure ulcers were most common. Delirium and confusion were diagnosed in 18% (n = 13); all were admitted to the ICU and required mechanical ventilation. Of note, of all patients studied, 59.2% (n = 42/71) had at least 1 complication, 32.4% (n = 23) had at least 2 complications, and 19.7% (n = 14) suffered 3 or more sequelae. Complications were significantly more common in ICU patients (n = 33/38, 87%), compared to HDU patients (n = 9/33, 27%) (OR 17.6, 95% CI 5.23, 59.21, p <0.05). CONCLUSION: In a subset of critically ill patients who recovered from severe COVID-19 infection, there was considerable short-term post-infectious and post-acute disability. Long-term follow-up of COVID-19 survivors is warranted.

Covid-19 pandemic research opportunity: Is the Middle East & North Africa (MENA) missing out?

BACKGROUND: The Covid-19 pandemic has caused fear and panic worldwide, forcing healthcare systems to disregard conventional practices and adopt innovation to contain the infection and death. Globally, there has been a rapid proliferation of research studies and clinical trials assessing risks, infectivity and treatment. METHODS: This review assesses the opportunities and challenges in the Middle East North Africa (MENA) region to engage in the conduct of high quality clinical trials during the Covid-19 pandemic. RESULTS: Opportunities are abundant for conducting clinical trials in MENA countries, including substantial cost savings, academic health centers, integrated health information systems, international accreditation, and international collaborations. Yet, the MENA region has missed out on opportunities to advance patient research during prior infectious disease outbreaks caused by the Severe Acute Respiratory Syndrome, Ebola, and the Middle East Respiratory Syndrome, as evidenced by the lack of concerted research and clinical trials from the region. A large vulnerable population, especially the poor expatriate work force, the current isolation of the health centers, and the lack of an expert network or field trained task force, all contribute to challenges preventing the formation of a pan Arab research enterprise for epidemics. CONCLUSION: Quality clinical research is critical during public health emergencies to identify treatments and solutions. The efficient conduct of clinical trials requires innovative strategies in research design, approval, and dissemination. Many countries in the MENA region have an opportunity to quickly ramp up research capacity and contribute significantly to the fight against the Covid-19 global threat.
