The investigation of the efficiency of basic life support education among high school students: Protocol, design and implementation of an interventional, prospective longitudinal, individually randomised, parallel 1:1 grouped trial.

Background: Basic life support (BLS) skills are crucial not only for healthcare workers but for all lay people as well. Timely recognition of out-of-hospital cardiac arrest (OHCA) and the initiation of BLS by bystanders before the arrival of healthcare personnel may improve survival. There are several methods of spreading BLS skills and improve BLS skill retention among lay people. One of these methods can be the education of adolescent school children. The introduction of mandatory BLS education in schools was very effective in some European countries to increase the rate of bystander BLS. Methods/design: The current study aims to investigate the efficacy of a BLS training and BLS curriculum among high school children in Hungary. Moreover, the investigators would like to optimise factors influencing skill retention in this first responder group and aim to compare two types of teaching methods: feedback given by the instructor or software-based feedback on the efficacy of chest compressions during the course. This study will be an interventional, assessor blinded, individually randomised parallel group trial recruiting 360 students. BLS skill retention will be assessed at the end of the course, two months after the training and six months after training. Discussion: The current study will increase our knowledge on the methods educating BLS among high school children. The results will help us to create an effective BLS curriculum at schools.Trial registration: ClinicalTrials.gov: NCT06016153. Prospectively registered on 08/2023.

Teaching nontechnical skills in the undergraduate education of health care professionals: a nationwide cross-sectional study in Hungary.

BACKGROUND: The aim of our cross-sectional study was to evaluate the current situation and curriculum of nontechnical skills (NTS) training in the undergraduate education of health care professionals in Hungary. METHODS: All institutes with relevant NTS training in Hungarian faculties of medicine and faculties of health sciences were asked to fill out a 19-item questionnaire. Descriptive statistics were performed, and the characteristics of NTS teaching and non-NTS teaching institutes were compared. The independent predictors of teaching NTS in a particular institute were identified with multiple logistic regression. RESULTS: Seventy-seven institutes responded (52% response rate), of which 66% trained NTS. The most frequent method of NTS training is talking about them during a practice or lecture, and less than half of NTS respondents use simulation. The most frequent cause of not teaching NTS is a lack of human or technical resources. The type of faculty (p = 0.025), academic year (p = 0.001), field of medicine (p = 0.025), and importance of teamwork (p = 0.021) differed between NTS and noNTS institutes. Teaching students in academic year two represented the only independent predictor of NTS education (p = 0.012). CONCLUSIONS: Our findings show that the undergraduate curriculum of Hungarian universities includes some type of NTS education; however, this education requires further development.

[Out-of-hospital adult basic life support: new guidelines and the involvement of bystanders]. / A kórházon kívüli felnott alapszintu újraélesztés új irányelvei és a laikusok bevonásának kérdései.

Survival rate for out-of-hospital cardiac arrest remains low across Europe. In the last decade, involving bystanders turned out to be one of the most important key factors in improving the outcome of out-of-hospital cardiac arrest. Beside recognizing cardiac arrest and initiate chest compressions, bystanders could be also involved in delivering early defibrillation. Although adult basic life support is a sequence of simple interventions that can be easily learnt even by schoolchildren, non-technical skills and emotional components can complicate real-life situations. This recognition combined with modern technology brings a new point of view in teaching and implementation. We review the latest practice guidelines and new advances in the education (including the importance of non-technical skills) of out-of-hospital adult basic life support, also considering the effects of COVID-19 pandemic. We briefly present the Szív City application developed to support the involvement of lay rescuers. Orv Hetil. 2023; 164(12): 443-448.

[In-hospital cardiac arrest and basic life support]. / Kórházon belüli keringésmegállás és alapszintu újraélesztés.

Survival of in-hospital cardiac arrests is still as low as 15-35%. Healthcare workers should closely monitor patients' vital signs, notice any deterioration, and initiate the necessary actions to prevent cardiac arrest. The introduction of early warning sign protocols (including the monitoring of respiratory rate, oxygen saturation, pulse, blood pressure, consciousness, etc.) can improve the recognition of periarrest patients during hospital stay. However, when a cardiac arrest occurs, healthcare workers should also be able to work in team and follow the relevant protocols delivering good quality chest compressions and early defibrillation. To achieve this goal, regular trainings, appropriate infrastructure and system-wide teamwork are needed. In this paper, we discuss the challenges of the first phase of in-hospital resuscitation and its integration into the hospital-wide medical emergency response system.

The efficacy of virtual distance training of intensive therapy and anaesthesiology among fifth-year medical students during the COVID-19 pandemic: a cross-sectional study.

BACKGROUND: The coronavirus disease (COVID-19) brought several challenges in medical education. The aim of our study was to investigate whether virtual distance trainings (VDT) organized during the COVID-19 pandemic at our university were effective in replacing in-person bed-side education in intensive therapy and anaesthesiology among fifth-year medical students, both from students' and instructors' perspectives. METHODS: This was a cross-sectional study consisting of three parts: a 20-item students' questionnaire filled out by students participating in VDT, a 22-item instructors' questionnaire filled out by instructors taking part in virtual distance education and a 20-item knowledge test completed by students participating in VDT, as well as by students visiting bed-side trainings (BT) during the same semester, before COVID-19 pandemic. The questionnaires focused on effectiveness, content, self-preparedness, technical background and interactivity of VDT. Instructors' and students' responses given to the common questions, as well as the knowledge test results were compared. Mann-Whitney U test was used for group comparisons and binary logistic regression was performed to analyze the influence of previous health-care experience on students' feeling of self-preparedness. RESULTS: One hundred thirthen students (response rate {RR}: 68%) and 29 instructors (RR: 97%) filled out the questionnaires. The majority of students found our VDT useful and effective; however, a considerable number of participants felt disadvantaged by taking VDT instead of BT sessions and would recommend keeping virtual distance education methods combined with BT. Instructors found VDT overall effective and deemed the transfer of their knowledge satisfactory; however, they described worse interactivity and contact with students during virtual sessions compared to in-person teaching. Instructors showed a clearer consensus that VDT should not replace BT in the future, while students' answers were more divided in this regard. Previous health-care experience did not influence students' feeling of self-preparedness. One hundred and twenty-seven students (56 after VDT {RR: 34%}; 71 after BT {RR: 67%}) completed the end-of-semester knowledge test. Students attending VDT performed better than students visiting BT (median score VDT:83.5 vs BT:77.3; p = 0.015). CONCLUSIONS: Virtual distance learning incorporating virtual practice sessions was effective in maintaining continuous education of intensive therapy and anaesthesiology among fifth-year medical students during the COVID-19 outbreak.

The timing of testing influences skill retention after basic life support training: a prospective quasi-experimental study.

BACKGROUND: Proper basic life support (BLS) is key in improving the survival of out-of-hospital cardiac arrest. BLS skills deteriorate in three to 6 months after training. One method to improve skill retention may be using the "testing effect" to test skills at the end of a BLS course. The aim of our study was to investigate whether either testing or the timing of such testing after BLS training have any influence on skill retention. METHODS: This was a post-test only, partial coverage, prospective quasi-experimental study designed to evaluate a BLS training course among 464 fifth year medical students at Semmelweis University in the first semester of 2013/2014. Groups were systematically but non-randomly assigned to either a control group that took no exam or one of two experimental groups that took an exam (N = 179, NoExam group; N = 165, EndExam group - exam at the end of the BLS training; N = 120, 3mExam group - exam 3 months after the BLS training). The ability to perform ten prescribed essential BLS steps was evaluated during a skill retention assessment 2 months after the course in the NoExam, 2 months after the course (and the exam) in the EndExam and 5 months after the course (2 months after the exam) in the 3mExam group to measure skill retention and the effect of our intervention. Scores were calculated for each BLS step, and also summed up as a total score. We used Kruskal-Wallis test to assess differences in skill retention. RESULTS: Overall, NoExam and EndExam groups showed similar skill retention. The mean total score (and many of the sub-scores) of students was significantly higher in the 3mExam group compared to both the NoExam and the EndExam groups, and there was no difference in the total score (and many of the sub-scores) of the latter two groups. The 3mExam group had less variability in total scores (and many of the sub-scores) than the other two groups. CONCLUSION: Our study provides evidence that testing these skills 3 months after BLS training may be more effective than either testing immediately at the end of the course or no testing at all.

[A potential best practice of cardiopulmonary resuscitation training by peer education in schools. First experiences of a health educative program]. / Egy lehetséges iskolai "jógyakorlat" az újraélesztés kortársoktatásában. Egy egészségfejlesztési program elso tapasztalatai.

Basic life support (BLS) teaching by peer-educators to school-age students was studied by evaluating their effectiveness. BLS resuscitation was taught by the internationally accepted four-stage skill teaching approach. The effectiveness of the training was followed by sociological measuring instruments (n = 91). Compared to the students' previous knowledge and attitudes about resuscitation, an increased willingness to adapt to an unexpected situation can be observed besides acquiring a reproducible method of CPR. The findings did not show significant age differences. Sensitivity and technical training in lay resuscitation is a successful educational process. The applied peer-education model is suitable for transferring resuscitation knowledge and skills. Orv Hetil. 2019; 160(46): 1816-1820.

Shortening the length of stay and mechanical ventilation time by using positive suggestions via MP3 players for ventilated patients.

Long stay in intensive care unit (ICU) and prolonged ventilation are deleterious for subsequent quality of life and surcharge financial capacity. We have already demonstrated the beneficial effects of using suggestive communication on recovery time during intensive care. The aim of our present study was to prove the same effects with standardized positive suggestive message delivered by an MP3 player. Patients ventilated in ICU were randomized into a control group receiving standard ICU treatment and two groups with a standardized pre-recorded material delivered via headphones: a suggestive message about safety, self-control, and recovery for the study group and a relaxing music for the music group. Groups were similar in terms of age, gender, and mortality, but the SAPS II scores were higher in the study group than that in the controls (57.8 ± 23.6 vs. 30.1 ± 15.5 and 33.7 ± 17.4). Our post-hoc analysis results showed that the length of ICU stay (134.2 ± 73.3 vs. 314.2 ± 178.4 h) and the time spent on ventilator (85.2 ± 34.9 vs. 232.0 ± 165.6 h) were significantly shorter in the study group compared to the unified control. The advantage of the structured positive suggestive message was proven against both music and control groups.

Comparison of the "real-life" diagnostic value of two recently published electrocardiogram methods for the differential diagnosis of wide QRS complex tachycardias.

OBJECTIVES: The diagnostic values of the aVR lead or "Vereckei algorithm," and the lead II R-wave peak time (RWPT) criterion, recently devised for the differential diagnosis of wide QRS complex tachycardias (WCTs), were compared. METHODS: A total of 212 WCTs (142 ventricular tachycardias [VTs], 62 supraventricular tachycardias [SVT], and eight preexcitation SVTs) from 145 patients with proven electrophysiologic diagnoses were retrospectively analyzed by seven examiners blinded to the electrophysiologic diagnoses. RESULTS: The overall test accuracy of the Vereckei algorithm was superior to that of the RWPT criterion (84.3% vs. 79.6%; p = 0.0003). The sensitivity of the Vereckei algorithm for VT diagnosis was greater than that of RWPT criterion (92.4% vs. 79.1%; p < 0.0001). The negative predictive value (NPV) for the Vereckei algorithm was also greater (77.8%; 95% confidence interval [CI] = 73.6% to 82.1%) than that of the RWPT criterion (61.6%; 95% CI = 57.6% to 65.6%). The specificity of the Vereckei algorithm was lower than that of the RWPT criterion (64.7% vs. 80.9%; p < 0.0001). The positive predictive value (PPV) was also lower for the Vereckei algorithm (86.4%; 95% CI = 84.4% to 88.4%) than for the RWPT criterion (90.9%; 95% CI = 89.1% to 92.8%). Incorrect diagnoses made by the Vereckei algorithm were mainly due to misdiagnosis of SVT as VT (65.7% of cases), and those made by the RWPT criterion were due to the more dangerous misdiagnosis of VT as SVT (72.5% of cases). CONCLUSIONS: The Vereckei algorithm was superior in overall test accuracy, sensitivity, and NPV for VT diagnosis and inferior in specificity and PPV to the RWPT criterion. All of these parameters were lower in "real life" than those reported by the original authors for each of the particular electrocardiographic methods.

Therapeutic suggestion helps to cut back on drug intake for mechanically ventilated patients in intensive care unit.

Research was conducted on ventilated patients treated in an intensive care unit (ICU) under identical circumstances; patients were divided into two groups (subsequently proved statistically identical as to age and Simplified Acute Physiology Score II [SAPS II]). One group was treated with positive suggestions for 15-20 min a day based on a predetermined scheme, but tailored to the individual patient, while the control group received no auxiliary psychological treatment. Our goal was to test the effects of positive communication in this special clinical situation. In this section of the research, the subsequent data collection was aimed to reveal whether any change in drug need could be demonstrated upon the influence of suggestions as compared to the control group. Owing to the strict recruitment criteria, a relatively small sample (suggestion group n = 15, control group n = 10) was available during the approximately nine-month period of research. As an outcome of suggestions, there was a significant drop in benzodiazepine (p < 0.005), opioid (p < 0.001), and the α2-agonist (p < 0.05) intake. All this justifies the presence of therapeutic suggestions among the therapies used in ICUs. However, repeating the trial on a larger sample of patients would be recommended.

Psychological support based on positive suggestions in the treatment of a critically ill ICU patient - A case report.

This case report describes the way psychological support based on positive suggestions (PSBPS) was added to the traditional somatic treatment of an acute pancreatitis 36-year-old male patient. Psychological support based on positive suggestions (PSBPS) is a new adjunct therapeutic tool focused on applying suggestive techniques in medical settings. The suggestive techniques usually applied with critically ill patients are based on a number of pre-prepared scripts like future orientation, reframing, positivity, supporting autonomy, etc., and other, very unique and personalized interventions, which are exemplified with verbatim quotations. We describe the way several problems during treatment of intensive care unit (ICU) patients were solved using suggestive methods: uncooperativeness, difficulties of weaning, building up enteral nutrition, supporting recovery motivation, and so on, which permanently facilitated the patient's medical state: the elimination of gastrointestinal bleeding, recovery of the skin on the abdomen, etc. Medical effects follow-up data at 10 months show that the patient recovered and soon returned to his original work following discharge.

Comparison of effects of different hand positions during cardiopulmonary resuscitation.

AIM: The technique of chest compression recommended in the recent international guidelines is different from that which was traditionally used in Hungary. While compression force, location, frequency and duty cycle are all identical, the position of the hand on the chest is different. The aim of our study was to compare these two methods concerning the area and location of the surface compressed on the chest wall. METHODS: Thirty-eight doctors were trained in both compression methods. Compressions were carried out on an AMBU Man-C manikin. The compressed surface, marked by using a carbon paper, was projected on to a standardised 10 mm x 10 mm matrix to measure the area and location. The chest surface was marked subsequently as green, yellow and red areas to identify the correct position, incorrect position and dangerous areas. All subjects did chest compressions using both techniques (I, International; H, traditional Hungarian) in a random order each for 30 s. RESULTS: The surface area compressed was significantly larger by the H method than the I method (73.46 (+/-17.11) versus 41.75 (+/-11.08), p<0.005). 8.07 (+/-1.91) cm2 of an area considered dangerous were compressed by the H method compared to 2.93 (+/-0.78) cm2 by the I method (p<0.005). CONCLUSION: Comparing the two different methods of chest compressions, the hand position recommended by the recent international guidelines seems to be more safe as it compresses a smaller area which might cause injury.

[Massive gastrointestinal bleeding in Henoch-Schoenlein purpura in an adult]. / Masszív gasztrointesztinális vérzés felnóttkori Schónlein-Henoch purpurában.

Henoch-Schoenlein syndrome in an adult patient, localised only to the gastrointestinal system is very rare. A 50 year old male was treated in our Intensive Department because of acute respiratory distress syndrome (ARDS) and renal failure. After temporary improvement massive gastrointestinal bleeding developed with shock. Blood was found in the descending duodenum without evident pathology at endoscopy. Angiogram showed bleeding at the hepatic flexure of the colon, which was successfully treated by a coil and bleeding was also present in the terminal part of the small intestine. The catheter was left in situ and the bleeding part of the bowel was painted intraoperatively, so we could resect the stained part of the intestine. Because of rebleeding, bowel resection was performed an other two occasions in the same way. The histology of the bowel showed Henoch-Schoenlein syndrome in each specimen. Our patient was totally non-responsive to treatment, which is usually successful in this disease. After the resections the bleeding stopped temporarily, but as the underlying disease was unmanageable the patient died but we have not found any surgical complication at autopsy. We think that this method in the surgical treatment of massive intestinal bleeding is very useful and effective.
