    Comparison of Bpap S/T and Average Volume-Assured Pressure Support Modes for Hypercapnic Respiratory Failure in the Emergency Department: a Randomized Controlled Trial
    (Galenos Publ House, 2021) Gören, Nurfer Zehra; Sanci, Emre; Coskun, Feride Fulya Ercan; Gursoylu, Duygu; Bayram, Basak
    Background: There is limited research into the utility of average volume-assured pressure support (AVAPS), a volume-assured pressure-controlled mode, especially in patients with hypercapnic respiratory failure. Aims: This study aimed at a randomized comparison of AVAPS and bilevel positive airway pressure spontaneous/timed (BPAP S/T) modes in non-invasive mechanical ventilation (NIMV) application with hypercapnic respiratory failure patients in the emergency department (ED). Study Design: Randomized controlled study. Methods: In this prospective randomized controlled study, 80 patients admitted to ED with hypercapnic respiratory failure requiring NIMV were randomly assigned to AVAPS or S/T groups using the sealed envelope method (33 patients in the S/T group, 47 patients in the AVAPS group). Data of arterial blood gas (ABG), vital parameters, Glasgow Coma Score (GCS), additional treatment needs, and clinical outcomes were evaluated, and the treatment success rates of both groups were compared. Results: A total of 80 patients, 33 in the S/T and 47 in the AVAPS group, were analyzed in the study. The pH values improved in the AVAPS group compared to the baseline (0.07 [0.04-0.10] vs 0.03 [0.00-0.11]). PaCO2 (partial pressure of carbon dioxide) excretion was faster in the AVAPS group than in the S/T group in the first hour (10.20 mmHg [6.20-19.20] vs. 4.75 ([-] 0.83-16.88)). The comparison of blood gas measurements showed no significant differences between the groups regarding the changes in PaCO2 and pH values over time (P=.141 and P=.271, respectively). During the ED follow-up, 3 (6.4%) patients in the AVAPS group and 5 (15.2%) patients in the S/T group needed intubation [Relative risk: 0.42 (95% CI: 0.11 to 1.64), P=.21]. Conclusion: In this study, improvements in blood gas parameters in the AVAPS group were faster compared to the S/T group; however, we did not find any significant difference between the groups in terms of clinical parameters. The AVAPS mode is as effective and safe as BPAP S/T in treating patients with hypercapnic respiratory failure in the ED.

    A De Novo Tool To Measure the Preclinical Learning Climate of Medical Faculties in Turkey
    (Edam, 2015) Yilmaz, Nilufer Demiral; Velipasaoglu, Serpil; Sahin, Hatice; Basusta, Bilge Uzun; Midik, Ozlem; Coskun, Ozlem; Budakoglu, Isil Irem; İfakat Tengiz, Funda
    Although several scales are used to measure general and clinical learning climates, there are no scales that assess the preclinical learning climate. Therefore, the purpose of this study was to develop an effective measurement tool in order to assess the preclinical learning climate. In this cross-sectional study, data were collected from 3,540 preclinical medical students of six medical faculties in Turkey. The methodology included the following activities: generate an item pool, receive expert opinions, perform a pretest to purify the instrument, and conduct factor and reliability analyses. According to the factor analysis, eight factors were determined and their contribution to the variance was 50.39%. In addition, the item factor loadings ranged from .31 to .91, Cronbach's alpha coefficients for the subscales ranged from .72 to .77, and the item-total correlation coefficients for the subscales ranged from .44 to .76. All the items significantly discriminated between the low- and high-performing students (t = 99.57; p = .01). The scale included 52 items with the following subscales: management, teaching, teaching staff, institutional commitment, emotions, inter-student relationships, physical environment, and motivation. The analysis of this newly developed Preclinical Learning Climate Scale (PLCS) indicated that its psychometric properties are appropriate and this scale can be employed to evaluate medical education programs.
