Assessment of Antimicrobial Consumption in Multi-Field Hospitals with Pediatric Inpatients: Conventional vs. Novel Pediatric-Adjusted Methodologies.

BACKGROUND: the objective of this study was to propose a methodology for the assessment of antimicrobial consumption (AMC) in pediatric inpatients and to estimate variances in consumption levels in multi-field hospitals with pediatric inpatients, calculated by means of the pediatric-adjusted methodology vs. the conventional methodology. METHODS: the pediatric-adjusted methodology based on the conventional ATC/DDD method and children's DDDs (cDDD) for antimicrobials were proposed and validated in a series of probabilistic sensitivity analyses of real clinical data extracted from the receipt notes of three multi-field hospitals. Differences in AMC in multi-field hospitals with pediatric inpatients, calculated by means of the proposed methodology vs. the conventional methodology, were assessed for a virtual cohort of inpatients, with the pediatric share increasing by 1%. RESULTS: in children ≤12 years old, assessment by the standard methodology resulted in a 59% underestimation of AMC from the levels based on prescribed doses, vs. a 25% underestimation for the proposed methodology. In a mixed-age virtual population of inpatients, the underestimation of consumption levels rose to 321% for the ATC/DDD methodology compared to the proposed one. CONCLUSIONS: the proposed methodology demonstrated a higher accuracy of AMC estimates compared to the conventional one and can be considered for the quantification of antimicrobial utilization in pediatric institutions and multi-field hospitals with a substantial share of pediatric inpatients.

Longitudinal Point Prevalence Survey of Antimicrobial Consumption in Russian Hospitals: Results of the Global-PPS Project.

Antimicrobial resistance is one of the key issues limiting the successful treatment of infectious diseases and associated with adverse medical, social and economic consequences on a global scale. The present study aims to evaluate antimicrobials prescribing patterns and assess progress in quality indicators in Russian multidisciplinary hospitals using three repetitive point prevalence studies (PPSs) over 4 years (Global-PPS 2015, 2017 and 2018). Out of 13,595 patients from 21 hospitals surveyed over the three time points, 3542 (26.14%) received antimicrobials, predominantly third-generation cephalosporins (44.7% in 2015, 34.1% in 2017 and 41.8% in 2018). Compliance with the hospital antibiotic guidelines was 74.8%, 66.8% and 74.3%, respectively. Indication for treatment was recorded in 72.6%, 84.1% and 82.6%, while stop/review date was documented only in 40.5%, 46.5% and 61.1% of cases. Perioperative antibiotic prophylaxis exceeded 1 day in 92%, 84% and 81% of cases. Targeted therapy rate at all time points did not exceed 15.1%, treatment based on the biomarkers rate-19.9%. For the part of PPS-2017 and 2018 analyzed in dynamics, no prominent trends were noted. The results of the project provide the basis for the development of appropriate antimicrobial stewardship programs tailored according to local practices for each hospital in the project.

Immune approaches in tuberculosis therapy: a brief overview.

TB is typically caused by Mycobacterium tuberculosis, a symbiotic bacterium present in one-third of the world's population. There any many factors triggering overt clinical disease in a small proportion of humans. In our view the major role in the process is played by the host's immune response, especially self-directed, destructive inflammation. Conventional chemotherapy produces bactericidal or bacteriostatic effects, but immunopathological changes can only be corrected by immunotherapy. Various attempts have been made to identify the optimal immune intervention. Some have shown promising effects, but many have failed. It is commonly believed that the field started in 1890: the year Robert Koch announced his tuberculin therapy. In the Pên Ts'ao Kang Mu, classical Chinese materia medica, published during Ming dynasty, Li Shi Chen (1518-1593) recommended, as a remedy for hemoptysis, to collect from the sputum "…blood lumps, roast them till they are black, and take then them as a powder". In retrospect, this is perhaps the earliest recorded reference relating to immunotherapy of TB with heat-killed mycobacteria. Modern science is obviously geared toward more palatable approach, but without hindsight from often disdained empirical evidence no progress can be made. The clinical experience from various trial and error processes is briefly discussed in this review.
