Effectiveness of the CRISP Method on the Primary Cardiac Arrhythmia Interpretation Accuracy of Nurses.

BACKGROUND: Accurate electrocardiogram (ECG) interpretation is key to quickly providing attention to patients, and the first health staff who evaluate ECGs are nurses. METHOD: This was a prospective study with a pre-posttest design. The study test included 15 ECGs related to primary cardiac arrhythmias. After pretest nurses were instructed on arrhythmia interpretation using the Cardiac Rhythm Identification for Simple People (CRISP) method, posttests were completed. RESULTS: There was a significant difference between the pretest scores of nurses who had postgraduate education on ECG interpretation and who did not (p = .002). Median test score increased from 3 (interquartile range [IQR] = 2-5) to 7 (IQR = 5-9) (p < .001). Participants mostly missed questions about heart blocks and were most successful with questions about fatal arrhythmias after education. CONCLUSION: The CRISP method is an effective, simple, and easy method for accurate ECG interpretation by nurses. The posttest scores of the participants, especially accurate interpretation of fatal arrhythmias, increased significantly after training. [J Contin Educ Nurs. 2020;51(12):574-580.].

Evaluation of electrocardiographic parameters in patients with epileptic seizure.

The aim of the study is to evaluate the changes in electrocardiographic parameters, including QTc dispersion (QTcd), Tpeak-Tend (Tp-e)/QTc ratio and P-wave dispersion (Pd), during the period without seizure activation in patients, presented to the emergency department (ED) with epileptic seizures. This prospective case-control study was conducted between January 2017 and January 2018. Patients, over 18 years old and presented to the ED with epileptic seizure, were consecutively included in the study. Interictal period ECGs of patients were obtained at least 2 hours after the end of the postictal period. ST-segment changes, QT interval, corrected QT interval (QTc), QTd, Pd, Tp-e, Tp-e dispersion (Tp-ed), Tp-e/QTc ratio and arrhythmias were evaluated in interictal ECGs. A total of 103 epileptic patients and 31 control cases were included in the study. Heart rate, QTc, QTcd, Pd, Tp-ed and Tp-e/QTc ratio were significantly higher in the epilepsy group than in the control group (p < 0.05 for all values). No statistically significant difference in those parameters was observed between the patients with known epilepsy and the patients who had seizure for the first time. There was also no statistically significant difference between patients who had recurrent seizures during the observation period and who did not. The patients with epileptic seizures had increased Pd, QTd, QTcd, Tp-ed and Tpe/QTc ratio during interictal period compared to healthy subjects. These electrocardiographic changes might be associated with an increased risk of dysrhythmia. However, prospective large cohorts with short- and long-term follow-up are needed for clinical reflections.

Role of Procalcitonin in Evaluation of the Severity of Acute Cholecystitis.

OBJECTIVE: The aim of this study is to investigate the relationship between procalcitonin (PCT) level and the severity of acute cholecystitis. MATERIALS AND METHODS: This study included 200 patients diagnosed with acute cholecystitis. To diagnose and assess the severity of acute cholecystitis; physical examination and abdominal ultrasound findings were evaluated and blood samples were taken to determine white blood cell (WBC) count, erythrocyte sedimentation rate (ESR), and levels of coagulation factors, blood gas, C-reactive protein (CRP) and PCT. Patients were classified into three stages, namely, mild, moderate, and severe, according to the severity of acute cholecystitis using the Tokyo guidelines. The role of PCT level in the assessment of severity of acute cholecystitis and the correlation between the stages and PCT level were statistically analyzed. RESULTS: Among patients with acute cholecystitis, 110 (55%) were classified as mild, 61 (30.5%) as moderate, and 29 (14.5%) as severe. Leukocytosis or leukopenia was positive in 48.5%, ESR elevation was found in 72.5%, CRP positivity in 55.5%, PCT elevation in 27%, and positive findings of ultrasonographic imaging in 54.5% of the patients. Serum WBC count, ESR, and CRP and PCT levels increased as the severity of disease increased (p<0.05). PCT could discriminate grade I from grade II-III with 95.45% sensitivity and 46.67% specificity at the best cut-off value of ≤0.52 (p<0.001). PCT could also discriminate grade III from grade I-II with 72.4% sensitivity and 90.06% specificity at the best cut-off value of >0.8 (p<0.001). CONCLUSION: PCT level may be considered to be a parameter that could be added to the assessment of the severity of acute cholecystitis in the Tokyo guidelines, although further studies are needed to support our findings.
