COVID-19 Vaccination Outcomes and Antibiotic Crisis and Overuse During the COVID-19 Pandemic in Bosnia and Herzegovina.

Background: COVID-19 has different presentations from mild flu like symptoms such as anosmia, dysgeusia, fever, sore throat, cough, dyspnea, headache, abdominal pain and diarrhoea to severe COVID-19 with the development of acute respiratory syndrome (ARDS), septic shock, metabolic acidosis, coagulation dysfunction, multiorgan failure or even death.

Objective: The aim of this research project was to present and highlight the outcomes of the vaccination against COVID-19 and the widespread use of antibiotics during the initial admission and treatment of COVID-19 patients in out of hospital settings.

Methods: This observational cross-sectional study was conducted between September 1st and September 24th 2021, during the fourth wave of COVID-19 outbreak in Bosnia and Herzegovina, among the patients admitted to the primary health care COVID-19 centre of Canton Sarajevo in Bosnia and Herzegovina.

Results: Patients were mostly female 213 (53.3%), with a mean age of 48.8±18.6, with hypertension 129 (32.3%) or diabetes mellitus 35 (8.7%) as comorbidities and being COVID-19 unvaccinated 236 (59.0%) COVID-19 unvaccinated patients expressed more fever (X ²=9.93, p<0.05), had typical COVID-19 chest X ray presentation (X ²=6.08, p<0.05) and abnormal lung auscultation sounds (X ²=5.43, p<0.05). Out of all patients, 312 (78.0%) have received antibiotics and 3 (0.75%) antivirotics such as favipiravir as therapy for the treatment of COVID-19. The mean duration of the antibiotic regime was 10.2 ± 7.5 days with a minimum of 3 days and maximum of 62 days. The minimum CRP value when antibiotics were prescribed was 0.1 (ref. value <5mg/l). The most prescribed antibiotic was doxycycline 172 (43.0%), followed by ceftriaxone 139 (34.7%) and azithromycin 108 (27.0%).

Conclusion: Our study showed that vaccination acts protective for the development of severe COVID-19 forms, as well as that antibiotics were overused among COVID-19 infected. The outcome of such malpractice could lead to antimicrobial resistance which will be seen in further years. Governmental agencies should advise physicians to change these trends.
