Enhancing hospital emergency response based on the experience of COVID-19.

INTRODUCTION: The COVID-19 pandemic required a significant response from global healthcare systems. In Belgium, the crisis began in March 2020, prompting quick action in hospitals. This study assesses the effectiveness of Belgium's hospital emergency plans and compares them with global standards for potential enhancements. METHODOLOGY: An online survey targeting CEOs of 60 Flemish general hospitals evaluated the deployment of hospital emergency coordination cells during the pandemic's first and fourth waves, utilizing various statistical analyses. RESULTS: Findings indicate a high establishment rate of COVID-19 coordination cells before the government's deadline. Despite this readiness, differences in leadership, involvement, and communication strategies were noted among hospitals. There was a notable shift towards hybrid meetings and an evolving role for coordination cells, highlighting the need for a more structured crisis management approach. CONCLUSION: The study concludes that while Flemish hospitals were quick to respond, the lack of a standardized framework suggests the potential for adopting models like the Hospital Incident Command System (HICS) for improved crisis management. Future research should examine the long-term effects of these strategies and the integration of comprehensive emergency management systems in Belgium's healthcare.

Pharmacokinetics and Target Attainment of ß-lactam Antibiotics in Older People: A Systematic Review of Current Literature.

BACKGROUND AND OBJECTIVE: (Patho)physiological changes in older people may influence the pharmacokinetics (PK), and consequently the target attainment, of ß-lactam antibiotics using standard dosing regimens. This systematic review compiles the current knowledge on the PK and target attainment of ß-lactam antibiotics in older people, with the aim to identify priorities for dose optimization in this patient population. METHODS: A systematic literature search of the PubMed and EMBASE databases was conducted. Relevant articles published prior to 1 December 2021 were identified as eligible when they included data on the PK of ß-lactam antibiotics in adults ≥ 65 years of age. Extracted information included reported PK parameters (volume of distribution, clearance [CL], elimination rate constant, intercompartmental CL, elimination half-life, area under the concentration-time curve, maximum and trough concentration), covariates on PK parameters, target attainment rate, and dosing recommendations. RESULTS: Ninety-one relevant articles were included in this review. Four main ß-lactam subclasses were represented: 59.3% on cephalosporins + cephamycins, 25.3% on penicillins, 15.4% on carbapenems, and 3.3% on monobactams; 65.9% of articles involved intravenous administration, 16.5% mixed administration routes, 12.1% oral administration, and 5.5% intramuscular administration. The majority of studies had a small sample size, often did not include detailed information on the study population and methods, and were fairly old. CL was, on average, decreased, while elimination half-life was prolonged in aged subjects compared with young subjects. Volume of distribution was generally similar between age groups. Most studies identified renal function as the most important contributor to altered drug CL. In only 30.8% of the articles, target attainment was studied, and in 35.7% of these articles, target attainment was found to be suboptimal. Dosing recommendations were incorporated in 87.9% of articles. CONCLUSION: Studies frequently fail to provide an evidence-based dosing recommendation for this diverse patient population. Model-based PK studies that address both physiological and disease-related changes are urgently needed. This review identified gaps of knowledge to set priorities for further research.

Combined oropharyngeal/nasal swab is equivalent to nasopharyngeal sampling for SARS-CoV-2 diagnostic PCR.

BACKGROUND: Early 2020, a COVID-19 epidemic became a public health emergency of international concern. To address this pandemic broad testing with an easy, comfortable and reliable testing method is of utmost concern. Nasopharyngeal (NP) swab sampling is the reference method though hampered by international supply shortages. A new oropharyngeal/nasal (OP/N) sampling method was investigated using the more readily available throat swab. RESULTS: 35 patients were diagnosed with SARS-CoV-2 by means of either NP or OP/N sampling. The paired swabs were both positive in 31 patients. The one patient who tested negative on both NP and OP/N swab on admission, was ultimately diagnosed on bronchoalveolar lavage fluid. A strong correlation was found between the viral RNA loads of the paired swabs (r = 0.76; P < 0.05). The sensitivity of NP and OP/N analysis in hospitalized patients (n = 28) was 89.3% and 92.7% respectively. CONCLUSIONS: This study demonstrates equivalence of NP and OP/N sampling for detection of SARS-CoV-2 by means of rRT-PCR. Sensitivity of both NP and OP/N sampling is very high in hospitalized patients.

Recognition of a disulfiram ethanol reaction in the emergency department is not always straightforward.

OBJECTIVES: Disulfiram is an adjunct in the treatment of alcohol use disorders, but case reports indicate that disulfiram ethanol reactions are not always recognized in the emergency department. Our first aim is to remind of this risk with two case reports of life-threatening reactions not immediately considered by the emergency physician. The second aim is to estimate the probability that a disulfiram reaction goes unrecognized with the use of a retrospective study of patients admitted to the emergency department. METHODS: Clinical files of patients admitted between October 1, 2010 and September 30, 2014 to the emergency department were retrospectively screened for the key words "ethanol use" and "disulfiram". Their diagnoses were then scored by a panel regarding the probability of an interaction. RESULTS: Seventy-nine patients were included, and a disulfiram-ethanol reaction was scored as either 'highly likely', 'likely' or 'possible' in 54.4% and as 'doubtful' or 'certainly not present' in 45.6% of the patients. The interrater agreement was 0.71 (95% CI: 0.64-0.79). The diagnosis was not considered or only after a delay in 44.2% of the patients with a 'possible' to 'highly likely' disulfiram interaction. One patient with a disulfiram overdose died and was considered as a 'possible' interaction. DISCUSSION AND CONCLUSIONS: A disulfiram ethanol interaction can be life threatening and failure to consider the diagnosis in the emergency department seems frequent. Prospective studies with documentation of the intake of disulfiram and evaluation of the value of acetaldehyde as a biomarker are needed to determine the precise incidence. Improving knowledge of disulfiram interactions and adequate history taking of disulfiram intake may improve the care for patients.
