Objectives The mortality rate associated with community-acquired pneumonia is still considered high as it occupies a leading position among all infectious diseases. The primary purpose of this study is to evaluate the implementation of the respiratory bacterial culture sampling in the clinical practice of the Russian Federation's therapeutic departments and its impact on inpatient care. Methods The study included 1,344 patients with community-acquired pneumonia. The analysis of the obtained data was performed using the statistical software package SPSS 23.0 (IBM SPSS Statistics). The description of quantitative indicators was carried out with an indication of the median (25; 75 percentile). Qualitative with an indication of the absolute and relative frequencies n (%). Results It was noted that a third of the sample did not pass through the first stage (bacterioscopy). We noticed the predominance of oropharyngeal flora in the results. The sputum collection was carried out on average 3 (1; 5) days after the start of hospitalization, while antibiotic therapy was prescribed to all patients on the first day, the results of the bacteriological study were ready on average 6 (4; 8th) calendar days after hospitalization, while in 20 (1.5%) cases, the patient was already discharged. Due to the inefficiency of the starting regimen, antimicrobial agents have changed in 84 (6.3%) patients and averaged 5.5 (4.0; 10.0) days from the start of hospitalization. Conclusions The violation of the technique and the time of sputum collection resulted in a reduction in the method's value.
