Hyperkalemia measurement between Blood Gas Analyser and Main Laboratory Biochemistry Analyser

@#Introduction: Potassium level is measured for patients with high risk of hyperkalemia in the emergency department (ED) using both blood gas analyser (BGA) and biochemistry analyser (BCA). The study was conducted to evaluate the correlation and agreement of potassium measurement between BGA and BCA. Materials and Methods: This is a prospective cross-sectional study on the data obtained from Hospital Universiti Sains Malaysia (Hospital USM) from Jun 2018 until May 2019. Blood samples were taken via a single prick from venous blood and sent separately using 1ml heparinised syringe and were analysed immediately in ED using BGA (Radiometer, ABL800 FLEX, Denmark) and another sample was sent to the central laboratory of Hospital USM and analysed by BCA (Architect, C8000, USA). Only patients who had potassium levels ≥5.0mmol/L on blood gas results were included. A total of 173 sample pairs were included. The correlation and agreement were evaluated using Passing and Bablok regression, Linear Regression and Bland-Altman test. Result: Of the 173 sample pairs, the median of potassium level based on BGA and BCA were 5.50mmol/L (IQR: 1.00) and 5.90mmol/L (IQR: 0.95) respectively. There was significant correlation between two measurements (p<0.001, r: 0.36). The agreement between the two measurements showed within acceptable mean difference which was 0.27 mmol/L with 95% limit of agreement were 1.21mmol/L to 1.73mmol/L. Conclusion: The result of blood gas can be used as a guide for initial treatment of hyperkalaemia in critical cases where time is of the essence. However, BCA result is still the definitive value.

A Study on the Diagnostic Discrepancy between Admission and Discharge in Hospital Universiti Sains Malaysia

@#Introduction: Accurate provisional diagnosis in the Emergency Department (ED) is important as it has a significant impact on safety. It also affects the patients’ treatment, length of stay and cost of treatment. The data on the accuracy of making diagnosis made by ED doctors is scarce and most results vary with different countries. This study was conducted to evaluate the accuracy of the diagnosis made by the ED doctors in Hospital Universiti Sains Malaysia (USM) and the factors contributed to the discrepancy. Method: This was a retrospective cross-sectional study conducted in Hospital USM from May 2016 to December 2017. Medical records of the patients who were admitted to the hospital were selected using simple random sampling methods. The folders were reviewed and the association within the categorised diagnosis accuracy was analysed using the ICD-10 classification. The sample size was 180 cases, and cases were divided into two main categories. The factors associated with the unmatched diagnosis from both patients and provider were then measured using multiple logistic regressions. Results: Hospital USM Emergency Department had 15.6 per cent of unmatched diagnosis and 84.4 per cent of matched diagnosis. No difference between age and gender in making accurate diagnosis. The odds of having unmatched diagnosis in patients from the green zone are 4.2 times higher compared to the red zone. Conclusion: ED Hospital USM has a high diagnostic accuracy, especially involving the patients in red zone and yellow zone.

Ultrasound findings of plasma leakage as imaging adjunct in clinical management of dengue fever without warning signs

@#ed as outpatients. Ultrasonographyevidence of plasma leakage either pleural effusion,thickened gallbladder wall, ascites or pericardial effusionwere compared with clinical findings and laboratoryparameters for plasma leakage. Results: Of the 83 dengue patients, eventually 72.3% haddengue fever with warning signs and 6.0% had severedengue fever. There were 38 patients who had subclinicalplasma leakage at initial presentation, 84.2% and 7.9% ofthem then progressed to dengue fever with warning signsand severe dengue respectively. There was a minimalagreement between serial bedside ultrasound andhaematocrit level in the detection of plasma leakage(observed kappa 0.135). Conclusions: Serial bedside ultrasound is an adjunctprocedure to physical examination and may detect plasmaleakage earlier compared to haemoconcentration. The earlyusage of serial ultrasound is of paramount importance indetecting dengue patients who are at risk of progressing tosevere dengue.

Study on the incidence of adverse events during intrahospital transfer of critical care patients from emergency department

@#Introduction: Emergency department (ED) plays a main role in the initial management of patients who are critically ill. These patients require intra-hospital transfer for continuation of care. Adverse events can occur during this short duration and the distance of intra -hospital transfer. The aims of this study were to determine the incidence of adverse events during intrahospital transfer from ED and to determine the factors associated. Methodology: This was a cross-sectional observational study done from November 2017 until December 2017 at ED Hospital Sultan Abdul Halim (HSAH), a 650-bedded tertiary hospital in the state of Kedah. All patients that were triaged to red zone, age 18 years and above, and involved in intra-hospital transfer to critical coronary unit, intensive care unit and wards were included. All cases were documented in proforma by the accompanying staff. Results: Among the 170 critically ill patients, only 29 patients (17.1%) experienced adverse events during intra-hospital transfer. The adverse events seen were hypotension (12.4%), desaturation (3.5%) and dislodged peripheral line (2.4%). Cardiorespiratory related diagnosis was the commonest presentation. Intra-hospital transfer during morning shift and evening shift has 79.5% (b=-1.59, OR=0.21, 95% CI: 0.06, 0.69, p=0.011) and 75.6% ((b=-1.41, OR=0.24, 95% CI: 0.08, 0.73, p=0.012) lesser odds of experiencing adverse events compare to night shift. Patients with vasopressor/inotropes had 9 times higher odds of experiencing adverse events during transportation, compared to patients with no vasopressor/inotropes (b=2.27, OR=9.70, 95% CI: 3.39, 27.72, p<0.001). Conclusions: Critical care patients who are involved in intrahospital transfer were at risk of adverse events such as hypotension, desaturation and dislodge peripheral line. Risk identification and maintaining level of care is important to minimize the adverse events during transfer. Patients had higher rates of adverse events if they were transferred during night shifts and on inotropic/vasopressor support

Outcome of Uncrossmatched Red Blood Cells Transfusion: A Retrospective Study at the University Hospital, Kelantan, Malaysia

Abstract@#Introduction: The practice of uncrossmatched red blood cells (URBC) transfusion has been accepted as part of resuscitation efforts in Emergency Departments (ED), especially in the case of hypovolemic shock secondary to blood loss. This study aimed to evaluate the outcome of patients who received URBC during the resuscitation process. Methods: This was a retrospective cross-sectional study among patients who received at least one unit of URBC in the ED at Hospital Universiti Sains Malaysia between March 1, 2016 and December 31, 2017. The outcome of patients who received URBC were analysed descriptively and presented as numbers and percentages. Simple log regression was used to analyse the association between the number of URBC given and the outcome of the patients. Results: A total of 106 patients were involved in this study, with 63 (59.4%) of them were male and 43 (40.6%) were female. The mean age of these patients was 41.58 years old. For the outcome, 25 patients (23.6%) had an activation of massive transfusion protocol (MTP), 37 patients (34.9%) received emergency surgical procedure, and 28 patients (26.4%) died during hospitalisation. The mean length of hospital stay was 10.65 days (SD: 17.4). Numbers of URBC received have a statistically significant association with mortality status (p = 0.015) and activation of MTP (p = 0.02), but no significant association with the need for emergency procedure (p = 0.469). Conclusion: The numbers of URBC transfused can be associated with mortality and the activation of MTP.

The Record-Setting Flood of 2014 in Kelantan: Challenges and Recommendations from an Emergency Medicine Perspective and Why the Medical Campus Stood Dry

Floods are considered an annual natural disaster in Kelantan. However, the record-setting flood of 2014 was a ‘tsunami-like disaster’. Hospital Universiti Sains Malaysia was the only fully functioning hospital in the state and had to receive and manage cases from the hospitals and clinics throughout Kelantan. The experiences, challenges, and recommendations resulting from this disaster are highlighted from an emergency medicine perspective so that future disaster preparedness is truly a preparation. The history of how the health campus was constructed with the collaboration of Perunding Alam Bina and Perkins and Willis of Chicago is elaborated.

Assessing Patient Pain Scores in the Emergency Department

Background: Pain management in the Emergency Department is challenging. Do we need to ask patients specifically about their pain scores, or does our observational scoring suffice? The objective of this study was to determine the inter-rater differences in pain scores between patients and emergency healthcare (EHC) providers. Pain scores upon discharge or prior to ward admission were also determined. Methods: A prospective study was conducted in which patients independently rated their pain scores at primary triage; EHC providers (triagers and doctors) separately rated the patients’ pain scores, based on their observations. Results: The mean patient pain score on arrival was 6.8 ± 1.6, whereas those estimated by doctors and triagers were 5.6±1.8 and 4.3±1.9, respectively. There were significant differences among patients, triagers and doctors (P< 0.001). There were five conditions (soft tissue injury, headache, abdominal pain, fracture and abscess/cellulites) that were significantly different in pain scores between patients and EHC providers (P<0.005). The mean pain score of patients upon discharge or admission to the ward was 3.3 ± 1.9. Conclusions: There were significant differences in mean patient pain scores on arrival, compared to those of doctors and triagers. Thus, asking for pain scores is a very important step towards comprehensive pain management in emergency medicine.

Theophylline toxicity: A case report of the survival of an undiagnosed patient who presented to the emergency department

Theophylline toxicity is a life-threatening toxidrome that can present to an emergency department. To ascertain an immediate provisional diagnosis in toxicology at the emergency department is very challenging, especially when the patient presents with altered mental status, because the clinical features of several toxidromes overlap. We report a case of survival of undiagnosed theophylline toxicity that required intubation for two days in the intensive care unit. This was the first case to have been reported from our department. Accurate diagnosis of a toxidrome by gaining adequate history and conducting a thorough physical examination and early serum toxicology screening, coupled with good knowledge of toxicology, will lead to better patient outcomes.
