The influence of undetected hemolysis on POCT potassium results in the emergency department.

Objectives: This study aimed to evaluate discrepancies in potassium measurements between point-of-care testing (POCT) and central laboratory (CL) methods, focusing on the impact of hemolysis on these measurements and its impact in the clinical practice in the emergency department (ED).

Methods: A retrospective analysis was conducted using data from three European university hospitals: Technische Universitat München (Germany), Hospital Universitario La Paz (Spain), and Erasmus University Medical Center (The Netherlands). The study compared POCT potassium measurements in EDs with CL measurements.

Association of physiological stress markers at the emergency department to readmission and death within 90 days: a prospective observational study.

Background: Predicting the risk of readmission or death in patients at the emergency department (ED) is essential in identifying patients who would benefit the most from interventions. We aimed to explore the prognostic value of mid-regional proadrenomedullin (MR-proADM), mid-regional pro-atrial natriuretic peptide (MR-proANP), copeptin, and high-sensitivity troponin T (hs-TnT) to identify patients with a higher risk of readmission and death among patients presenting with chest pain (CP) and/or shortness of breath (SOB) in the ED.

Methods: This single-center prospective observational study included non-critically ill adult patients with a chief complaint of CP and/or SOB who visited the ED at Linköping University Hospital.

Failure Mode and Effects Analysis (FMEA) at the preanalytical phase for POCT blood gas analysis: proposal for a shared proactive risk analysis model.

Objectives: Proposal of a risk analysis model to diminish negative impact on patient care by preanalytical errors in blood gas analysis (BGA).

Methods: Here we designed a Failure Mode and Effects Analysis (FMEA) risk assessment template for BGA, based on literature references and expertise of an international team of laboratory and clinical health care professionals.

Results: The FMEA identifies pre-analytical process steps, errors that may occur whilst performing BGA (potential failure mode), possible consequences (potential failure effect) and preventive/corrective actions (current controls).

Point-of-care testing in the overcrowded emergency department--can it make a difference?

Emergency departments (EDs) face several challenges in maintaining consistent quality care in the face of steadily increasing public demand. Improvements in the survival rate of critically ill patients in the ED are directly related to the advancement of early recognition and treatment. Frequent episodes of overcrowding and prolonged waiting times force EDs to operate beyond their capacity and threaten to impact upon patient care.

Cutting costs: the impact of price lists on the cost development at the emergency department.

It was shown that physicians working at the Swedish emergency department (ED) are unaware of the costs for investigations performed. This study evaluated the possible impact of price lists on the overall laboratory and radiology costs at the ED of a Swedish university hospital. Price lists including the most common laboratory analyses and radiological investigations at the ED were created.

Cost awareness among Swedish physicians working at the emergency department.

Background: In Sweden the public health system is subject of increasing budget problems. Medical training in Sweden does not yet focus on the cost aspects in patients diagnoses and treatment.

Study Objectives: This study was carried out to survey the general knowledge among physicians working in the emergency department about the cost of the usual diagnostic tests used in ruling out pulmonary embolism.

[Burning feet].

After walking barefoot over hot sand, a 75-year-old man developed second-degree burns on the soles of both feet. His case history revealed diabetes mellitus with diabetic polyneuropathy and macroangiopathy. Since wound healing was protracted, antibiotic treatment was initiated.
