Influence of comorbid pathology and age on the duration of inpatient treatment in adult patients with respiratory synctyl virus infection

Purpose of the study. To analyze the influence of comorbid pathology and age on the duration of inpatient treatment of adult patients with respiratory syncytial virus infection.
Materials and methods. An observational retrospective cross-sectional study was conducted of 3821 patients who were treated at the St. Petersburg State Budgetary Institution “Clinical Infectious Diseases Hospital named after. S.P. Botkin” with the main diagnosis B97.4 “Respiratory syncytial virus infection” for the period from January to December 20023. The influence of comorbid pathology and patient age on the duration of hospitalization was analyzed.
Results. A significant increase in the length of hospitalization in patients with respiratory syncytial virus was observed when combined with the following comorbid conditions: J12 “Viral pneumonia, not elsewhere classified”; J15 “Bacterial pneumonia, not elsewhere classified”; G40 “Epilepsy”; K75 “Other inflammatory diseases of the liver”; G62 “Other polyneuropathies”; B27 “Infectious mononucleosis.” In all cases p < 0.001. A relationship was found between the duration of hospitalization and the age of the patients – an increase in age by 2.718 times was accompanied by an increase in the duration of hospitalization by 10.60%.
Conclusion. The results obtained indicate age and comorbid pathology as significant predictors of increasing the duration of hospital treatment for respiratory syncytial infection.
