Introduction: The coronavirus disease 2019 (COVID-19) pandemic has caused a worldwide emergency. The disease is characterized primarily by symptoms of the respiratory system, but also by systemic inflammation. Since the onset of the disease, there has been a need for biomarkers to predict the severity of the clinical picture and the outcome of the disease. The aim of this study is to evaluate systemic inflammatory markers for predicting severity of COVID-19. Methods: The study was conducted at the Sarajevo Canton Health Center on a total of 170 adults suffering from COVID-19. 70 subjects had mild clinical picture, while the control group consisted of 100 subjects with moderate clinical picture. The results of complete and differential blood counts, C-reactive protein (CRP), and systemic inflammatory indexes (SII) (neutrophil/lymphocyte ratio [NLR], derived NLR [dNLR], platelet/lymphocyte ratio [PLR], and SII) were used to compare the groups. IBM SPSS Ver. 23 was used for statistical analysis and data processing. Results: The proportion of male patients in the group with a milder clinical picture was higher than the proportion of male patients with a moderate clinical picture, p = 0.016. The values of leukocytes and neutrophils were higher in patients with a moderate clinical picture (p = 0.006 and p < 0.001, respectively). The values of all inflammatory indexes (NLR, dNLR, PLR and SII) were higher in patients with a moderate clinical picture of COVID-19 than in patients with a mild clinical picture (p < 0.001 for NLR, dNLR, and SII; p = 0.023 for PLR). In the research, patient age showed no correlation and CRP showed no correlation with SII. Conclusion: SII show higher values in patients with a moderate compared with a mild clinical picture of COVID-19. These parameters can be cost-effective and useful indicators in patient classification, diagnosis, and probably in monitoring patients with COVID-19.
Background: A laboratory professional concerned with the quality of work in medical-biochemical laboratories ensures the accuracy and precision of laboratory analyses through the implementation of international and European guidelines for working with hazardous substances, through the availability and implementation of Standard Operating Procedures (SOPs). Laboratory hazards that affect the concentration and safety of workers arise from laboratory deficiencies such as: lack of preventive measures, knowledge and skills implemented through SOPs and good laboratory practice. Biophysical hazards in medical laboratories are manifested by needles and sharp objects, infectious materials, noise, vibration, radiation, poor air quality, temperature inversions. Objective: The aim of the research was to raise awareness of the quality of work in medical-biochemical laboratories in order to ensure the safety of workers. Methods: A cross-sectional questionnaire-based study was conducted among 100 laboratory professionals from Bosnia and Herzegovina (BiH) and Croatia. The research was conducted over a period of three months. Results: A higher percentage of exposure to infectious agents and needles and sharp objects was found among respondents from BiH compared to CRO (p=0.018 and p=0.001, respectively). We found that respondents employed in accredited laboratories are aware of exposure to hazards in a high percentage related to infectious agents, toxins (p=0.0012 and p=0.0046, respectively). A significant statistical difference was found between respondents with BiH and respondents with CRO in terms of knowledge of accreditation standards of medical-biochemical laboratories (p=0.0155). Respondents who have standard operating procedures available are aware of the hazards of infectious agents (p=0.0001), toxins (p=0.0466), needles and sharp objects (p=0.0052), noise (p=0.0030), vibration (p=0.0007) and extreme temperatures (p=0.0014). Conclusion: Efficient implementation and continuous compliance with the ISO 15189: 2018 standard requires constant commitment and active participation of laboratory staff. Laboratories must have standard operating procedures in place and actively monitor their use.
Introduction: COVID-19 is an infectious disease caused by the severe acute respiratory syndrom coronavirus 2 and causes a series of respiratory symptoms. Considering the appearance and development of symptoms, the course of COVID-19 can go from mild to severe. Depending on the course of COVID-19, the laboratory parameters change a lot, trying to defend the organism against the foreign pathogen and all the changes it causes. Therefore, the aim of this study is to observe the differences between biochemical, hematological and coagulation parameters depending on the disease stage of COVID-19 patients. Material and methods: We conducted cross-sectional study which included 160 COVID-19 patients from Sarajevo, Bosnia and Herzegovina. Biochemical, hematological and coagulation analyzes were performed. Results: COVID-19 patients with a severe clinical course have higher average values of fibrinogen (6.53±4.47,p<0.001), D-dimer (6.89±7.81, p<0.001), APTT (32.05±5.96, p=0.002), eosinophil (0.66±0.09, p=0.002) and CRP (93.42±75.86, p= 0.023), and lower values of lymphocytes (1.04±0.98, p<0.001), monocytes (0.45±0.3, p<0.001), compared to COVID-19 patients with a mild clinical course. COVID-19 patients with a severe clinical course had higher average values of neutrophils (10.12±5.80, p=0.002) and lower values of reactive lymphocytes (0.02±0.03, p<0.001) compared to COVID-19 patients with a mild clinical course. Conclusion: Biochemical, hematological and coagulation parameters can be a sensitive and specific biomarker for distinction of mild and severe COVID-19.

Background and Purpose: Improper distribution of health workers is a worldwide problem, especially in developing countries. The shortage of health personnel has been intensified over the past two decades as a result of the emigration of health workers from developing countries to developed ones and disparities between urban and rural regions. Materials and Methods: This cross-sectional, quantitative, and descriptive study was conducted at the University of Sarajevo, Faculty of Health Studies, for two months. The study included 203 3rd-year and 4th-year undergraduate students of all study programs. The chi-square test was used to examine the difference between students’ attitudes about leaving according to gender, grade point, foreign language learning, and high school graduation, as well as different statements of intention to leave or stay. Results: Of 203 respondents, 49(24.1%) were male and 154(75.9%) were female. Thirty-four students (16.75%) stated their attitude towards the definitive departure. Also, 129 students (63.55%) were thinking about leaving after graduation, while 40 students (19.7%) wanted to continue their life in Bosnia and Herzegovina after their studies. Almost half of the female students (49.26%) and slightly more than half of the male students (14.28%) think about leaving after their studies, with a statistically significant difference between men and women who think about leaving and those who stay. The positive attitudes, which the students who are leaving, for the most part, agreed upon were the acquisition of life experience that their occupation profile was sought in other countries, and career development and professional development. The reasons why most students consider leaving the country after their studies are due to the attitude that their education and degree are more valued in other countries, higher living standards in other fields, and career development and professional development. Conclusion: To prevent the migration of health students, retention policies are needed that target immigrant staff. These policies can be extremely important in preventing the problem of a lack of quality health staff in the near future.
The principal role of biochemical laboratories is responsibility for reliable, reproducible, accurate, timely, and accurately interpreted analysis results that help in making clinical decisions, while ensuring the desired clinical outcomes. To achieve this goal, the laboratory should introduce and maintain quality control in all phases of work. The importance of applying the Six SIGMA quality model has been analyzed in a large number of scientific studies. The purpose of this review is to highlight the importance of using six SIGMA metrics in biochemical laboratories and the current application of six SIGMA metrics in all laboratory work procedures. It has been shown that the six SIGMA model can be very useful in improving all phases of laboratory work, as well as that a detailed assessment of all procedures of the phases of work and improvement of the laboratory's quality control system is crucial for the laboratory to have the highest level of six SIGMA. Clinical laboratories should use SIGMA metrics to monitor their performance, as it makes it easier to identify gaps in their performance, thereby improving their efficiency and patient safety. Medical laboratory quality managers should provide a systematic methodology for analyzing and correcting quality assurance systems to achieve Six SIGMA quality-level standards.
