Assessment and Application of the Hear Score in Remote Emergency Medicine Outposts in Bosnia and Herzegovina.

Background and Objectives. In emergency departments, chest pain is a common concern, highlighting the critical importance of distinguishing between acute coronary syndrome and other potential causes. Our research aimed to introduce and implement the HEAR score, specifically, in remote emergency outposts in Bosnia and Herzegovina. Materials and Methods. This follow-up study conducted a retrospective analysis of a prospective cohort consisting of patients who were admitted to the remote emergency medicine outposts in Canton Sarajevo and Zenica from 1 November to 31 December 2023. Results. This study comprised 103 (12.9%) patients with low-risk HEAR scores and 338 (83.8%) with high-risk HEAR scores, primarily female (221, 56.9%), with a mean age of 63.5 ± 11.2). Patients with low-risk HEAR scores were significantly younger (50.5 ± 15.6 vs. 65.9 ± 12.1), had fewer smokers (p < 0.05), and exhibited a lower incidence of cardiovascular risk factors compared to those with high-risk HEAR scores. Low-risk HEAR score for prediction of AMI had a sensitivity of 97.1% (95% CI 89.9-99.6%); specificity of 27.3% (95% CI 22.8-32.1%); PPV of 19.82% (95% CI 18.67-21.03%), and NPV of 98.08% (95% CI 92.80-99.51%). Within 30 days of the admission to the emergency department outpost, out of all 441 patients, 100 (22.7%) were diagnosed with MACE, with AMI 69 (15.6%), 3 deaths (0.7%), 6 (1.4%) had a CABG, and 22 (4.9%) underwent PCI. A low-risk HEAR score had a sensitivity of 97.0% (95% CI 91.7-99.4%) and specificity of 27.3% (95% CI 22.8-32.1%); PPV of 25.5% (95% CI 25.59-28.37%); NPV of 97.14% (95% CI 91.68-99.06%) for 30-day MACE. Conclusions. In conclusion, the outcomes of this study align with existing research, underscoring the effectiveness of the HEAR score in risk stratification for patients with chest pain. In practical terms, the implementation of the HEAR score in clinical decision-making processes holds significant promise.

OHCA in Bosnia and Herzegovina: Before and During the COVID-19 Pandemic.

Background: Out-of-hospital cardiac arrest (OHCA) refers to the cessation of mechanical cardiac activity outside healthcare facilities which requires prompt intervention and intensive resuscitative efforts. The COVID-19 pandemic has caused significant disruptions to OHCA systems-of-care, adversely affecting every component of the chain of survival. Objective: The objective of this study was to examine the potential impacts of the COVID-19 pandemic on OHCA events, to draw comparisons between the period before and during the COVID-19 pandemic. Methods: This cross-sectional study encompassed data pertaining to all OHCA incidents attended to by the Emergency Medical Service of Canton Sarajevo, covering the period from January 2017 to December 2022, before and during the COVID-19 pandemic. Results: During observed period, a total of 1418 [796 (56.1%) before and 622 (43.9%) during COVID-19 pandemic] OHCA events have occurred in Canton Sarajevo of which 297 (20.9 %) [180 (12.7%) before and 117 (8.2%) during COVID-19 pandemic] obtained ROSC. After a 30-day period following the ROSC) it was observed that the predominant outcome, accounting for 181 (12.7%) [106 (7.4%) before and 75 (5.2%) during COVID-19 pandemic] of cases, was a complete recovery. An examination before and during COVID-19 pandemic revealed a decline in OHCA during the year 2021 and 2022 when COVID-19 pandemic was at its highest in the country Being younger, quicker EMT response time and individuals with the initial rhythm of VF or VT were significantly associated with obtaining ROSC (p<0.05). Only 48 (3.3%) of 1418 OHCA events were assisted by bystanders There was no report of AED usage. Conclusion: In conclusion, our investigation highlights the impact of the COVID-19 pandemic on OHCA events in Canton Sarajevo, revealing a decrease in OHCA incidence and a reduction in cases achieving ROSC. Notably, EMT response time was shorter during the pandemic.

Comparison between conventional open-heart valve surgery and minimally invasive valve replacement surgery regarding the length of hospital stay and usage of blood derivates: insights from a single-centre, single-surgeon study conducted in Bosnia and Herzegovina.

Aim To analyse the correlation between different surgical methodologies employed in valve diseases treatment and their subsequent impact on the duration of hospitalization. Methods This retrospective study conducted at the Clinical Centre of the University of Sarajevo analysed medical records of 163 valve disease patients treated between January 2019 and November 2022. The patients were divided into two groups: 77 had openheart valve surgery and 86 underwent minimally invasive cardiac surgery (MICS). Results The mean duration of the surgical procedures was 3.9±1.3 hours, with conventional open-heart surgery requiring an average of 3.6±1.1 hours and minimally invasive cardiac surgery (MICS) procedure 4.2±1.5 hours. No substantial disparities were found in the total length of hospitalization between the two groups, as both conventional (8.2±4.5 days) and MICS (8.7±7.0 days) demonstrated similar duration. Similarly, the total duration of intensive care unit (ICU) stay displayed similarity, with conventional surgery patients staying an average of 3.9±2.8 days and MICS patients of 4.2±4.1 days. The pattern of blood transfusion and fresh-frozen plasma usage revealed higher rates in the conventional valve surgery group comparing to the MICS group. Conclusion Minimally invasive valve surgery, despite slightly longer operative times, resulted in lower blood transfusion requirements and comparable hospitalization and ICU stay.

HEART Score and Its Implementation in Emergency Medicine Departments in the West Balkan Region-A Pilot Study.

BACKGROUND: Chest pain represents a prevalent complaint in emergency departments (EDs), where the precise differentiation between acute coronary syndrome and alternative conditions assumes paramount significance. This pilot study aimed to assess the HEART score's implementation in West Balkan EDs. METHODS: A retrospective analysis was performed on a prospective cohort comprising patients presenting with chest pain admitted to EDs in Sarajevo, Zenica, and Belgrade between July and December 2022. RESULTS: A total of 303 patients were included, with 128 classified as low-risk based on the HEART score and 175 classified as moderate-to-high-risk. The low-risk patients exhibited younger age and a lower prevalence of cardiovascular risk factors. Laboratory and anamnestic findings revealed higher levels of C-reactive protein, ALT, and creatinine, higher rates of moderately to highly suspicious chest pain history, a greater number of cardiovascular risk factors, and elevated troponin levels in moderate-to-high-risk patients. Comparatively, among patients with a low HEART score, 2.3% experienced MACE, whereas those with a moderate-to high-risk HEART score had a MACE rate of 10.2%. A moderate-to-high-risk HEART score demonstrated a sensitivity of 91.2% (95%CI 90.2-93.4%) and specificity of 46.5% (95%CI 39.9-48.3%) for predicting MACE. CONCLUSION: This pilot study offers preliminary insights into the integration of the HEART score within the emergency departments of the West Balkan region.

COVID-19 vaccination knowledge, attitudes and practices among the general population of Romania during the third wave of COVID-19 pandemic.

Objective: Romania began its COVID-19 immunization programme with approved vaccinations in three stages, as follows: The first step of vaccination is for health and social professionals, the second stage is for high-risk persons and the third stage is for the remainder of the general public. This study aims at assessment of knowledge, attitude and practice towards COVID-19 and vaccination against COVID-19 in the Romanian population during the third wave of the pandemic. Methods: This cross-sectional study was based on a Bosnian and Herzegovinian study on COVID-19 vaccination during the country's third wave of COVID-19 pandemic. Results: Our study sample, dominantly female (629; 61.0%), with a bachelor's degree (734; 71.2%), either single (539; 52.3%) or in a relationship (363; 35.2%), engaged in intellectual labour (910; 88.3%) and living in an urban environment (874; 84.8%) with a mean age of 25.07 ± 8.21 years, 294 (28.5%) people with COVID-19 symptoms and 86 (8.3%) were tested COVID-19 positive, had a mean knowledge score of 16.38 ± 4.0 with correct answer rates on questions ranging from 30.1% to 88.2%. Being single (odds ratio = 3.92, p = 0.029) or in a relationship (odds ratio = 3.79, p = 0.034), having a bachelor's degree and higher (odds ratio = 1.61, p = 0.006) and being COVID-19 tested (odds ratio = 1.82, p < 0.001) were associated with higher knowledge test scores. Our sample had relatively optimistic attitudes towards final COVID-19 disease containment (712; 69.1%) and vaccination programmes (679; 65.9%). The majority of the sample followed socio-epidemiological measures and did not visit places of mass social gatherings (666; 64.1%) and wore masks (992; 95.7%) while being outside their home. In terms of vaccination rates, 382 (37.0%) of the individuals were presently immunized against COVID-19. Higher knowledge test scores (>15 points) (odds ratio = 1.66, p = 0.002) and positive attitudes of this study (odds ratio = 1.59, p = 0.001, odds ratio = 4.16, p < 0.001) were identified as independent predictors for vaccinating against COVID-19. Conclusion: Romanian citizens have had good knowledge, optimistic attitudes and appropriate practices towards COVID-19 vaccination during the third wave of COVID-19 outbreak in the country. Higher knowledge regarding the disease and vaccination against it not only increased attitudes towards the end of the pandemic, but also increased the willingness to be vaccinated and to avoid infection risk factors.

Echocardiographic Findings of Covid-19 Patients in Canton Sarajevo During the Third Wave of the Covid-19 Pandemic.

Background: Increasing evidence indicates that COVID-19 may result in cardiac issues in certain individuals, such as myocarditis, arrhythmias, and heart failure. Ongoing research on echocardiographic manifestations is still limited. Objective: To investigate the incidence and patterns of left and right ventricular dysfunction in COVID-19 patients. Methods: This study retrospectively observed COVID-19 patients admitted to the Clinical Center of University of Sarajevo during the third wave, with a particular focus on cardiac evaluations. Results: Our patients, predominantely male 155 (72.4%), with a mean age of 66.2±11.4, having hypertension 86 (40.1%), diabetes mellitus 61 (28.5%), hyperlipidemia 144 (67.3%), were active smokers 87 (40.6%), had family history of cardiovascular diseases 123 (57.5%) and were COVID-19 positive 95 (44.4%), presented because of chest pain 78 (36.4%), dyspnea 103 (48.1%), palpitations 67 (31.3%), fatigue 106 (49.5%) and peripheral oedema 30 (14.0%). COVID-19 patients reported much higher symptoms of dyspnea (65 (68.4%) vs 38 (31.9%)) and fatigue (73 (76.8%) vs 33 (27.7%)) than COVID-19 negative patients. On the initial laboratory report, COVID-19 patients had a significantly (p<0.05) higher mean score of C-reactive protein (24.0±4.8 vs. 6.0±2.1), D-dimer (1.6±2.5 vs 0.8±0.6), ALT (94.8±17.2 vs 36.5±19.9) and creatinine (128.0±80.8 vs. 93.4±40.1) when compared to COVID-19 negative patients. COVID-19 patients had enlarged left atrium diametes (31.6±5.6 vs 27.5±5.3), enlarged left ventricular diameter both in systole (27.9±18.1 vs 23.3±16.3) and diastole (39.3±24.1 vs 34.9±22.7), reduced left ventricular ejection fraction (53.5±9.2 vs 59.8±4.3) and elevated right ventricular systolic pressure (37.0±16.4 vs 35.1±8.6). Conclusion: COVID-19 patients had enlarged left atrium, enlarged systolic and diastolic left ventricular diameter, reduced left ventricular ejection fraction and elevated right ventricular systolic pressure.

Sleep quality and patterns of young West Balkan adults during the third wave of COVID-19 pandemic: a cross-sectional study.

OBJECTIVES: To evaluate the sleep patterns among young West Balkan adults during the third wave of the COVID-19 pandemic. DESIGN AND SETTING: Cross-sectional study conducted using an anonymous online questionnaire based on established sleep questionnaires Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI) (February-August 2021). PARTICIPANTS: Young adults of Bosnia and Herzegovina, Croatia and Serbia. RESULTS: Of 1058 subjects, mean age was 28.19±9.29 years; majority were women (81.4%) and students (61.9%). Compared with before the pandemic, 528 subjects (49.9%) reported a change in sleeping patterns during the pandemic, with 47.3% subjects reporting sleeping less. Mean sleeping duration during the COVID-19 pandemic was 7.71±2.14 hours with median sleep latency of 20 (10.0-30.0) min. Only 91 (8.6%) subjects reported consuming sleeping medications. Of all, 574 (54.2%) subjects had ISI score >7, with majority (71.2%) having subthreshold insomnia, and 618 (58.4%) PSQI score ≥5, thus indicating poor sleep quality. Of 656 (62.0%) tested subjects, 464 (43.9%) were COVID-19 positive (both symptomatic and asymptomatic) who were 48.8%, next to women (70%), more likely to have insomnia symptoms; and 66.9% were more likely to have poor sleep quality. Subjects using sleep medication were 44 times, and subjects being positive to ISI 15.36 times more likely to have poor sleep quality. In contrast, being a student was a negative independent predictor for both insomnia symptoms and poor sleep quality, and mental labour and not working were negative independent predictors for insomnia symptoms. CONCLUSIONS: During the third wave of the pandemic, sleep patterns were impaired in about half of young West Balkan adults, with COVID-19-positive subjects and being women as positive independent predictors and being a student as negative independent predictor of impaired sleep pattern. Due to its importance in long-term health outcomes, sleep quality in young adults, especially COVID-19-positive ones, should be thoroughly assessed.

Knowledge, attitudes and practices during the second wave of COVID-19 outbreak: a cross-sectional study from various perspectives.

Aim To investigate knowledge, attitudes and practice towards COVID-19 among selected population. Methods An anonymous online questionnaire based on a Chinese study was distributed via online social media platforms among general population of Bosnia and Herzegovina, Germany, India, Kosovo and Romania. Results In total 1032 subjects, predominately females, 615 (59.6%) with a mean age of 31.23±12.94 years, single, 705 (68.3%), with high school degree or lower, 469 (45.4%), students, 528 (51.1%) and living in an urban environment, 824 (79.8%), have completed the survey. The median knowledge score was 10.0 (range 0-12). Being male (ß: -0.437; p=0.003) and older (ß: -0.028; p<0.001) were associated with lower knowledge scores, while being single (ß: 1.026; p<0.001) and mental labour employee (ß: 0.402; p=0.032) were associated with higher knowledge scores. The vast majority of subjects had not visited crowded places, 630 (61.0%) and wearing masks when they were going out, 928 (89.9%). Being female (OR=0.731; p=0.022), having higher knowledge scores (OR=0.929; p=0.017) and being a mental labour employee (OR=0.713; p=0.031) decreased the exposure to crowded places. High school or lower education level (OR=0.616; p=0.024) decreased the action of wearing a mask in public places, while higher knowledge scores (OR=1.112; p=0.013) increased it. Conclusion Our study suggests that residents of the selected regions have had good knowledge, pessimistic attitudes and relatively appropriate practices towards COVID-19 during the second wave of the outbreak.
