Patient Safety Related to Microbiological Contamination of the Environment of a Multi-Profile Clinical Hospital. | LitMetric

AI Article Synopsis

  • Nosocomial infections are a major problem for hospitals and society, prompting a study to analyze the microbiological cleanliness of a large clinical hospital in Poland from 2012 to 2018.
  • The study used quantitative and qualitative methods to assess air and surface contamination in hospital environments, finding that 21.8% of samples tested positive for microorganisms, with 20.8% of those potentially harmful to patients.
  • The research highlighted that higher levels of dangerous microorganisms were found in sanitary facilities, leading to recommendations for specific cleaning and disinfection protocols in areas that require strict microbiological safety standards.

Article Abstract

Nosocomial infections pose a serious burden for hospitals, patients, and the entire society. The aim of the study was to assess the microbiological cleanliness of the hospital environment through quantitative and qualitative analysis of microbiological contamination of air and surfaces in inpatient treatment facilities, based on the example of a large clinical hospital in Poland. Data were collected between 2012 and 2018 in premises of a large teaching hospital in Gdansk using the sedimentation method and the impact method using the Aerideal apparatus (Biomerieux). In the analyzed clinical center, the microbiological cleanliness tests in most of the hospital rooms in the analyzed period showed an acceptable number of saprophytic microorganisms. Of all the tested samples, 1159 (21.8%) were positive, indicating the presence of microorganisms in the tested sample. Species potentially pathogenic for hospital patients were identified, constituting 20.8% of all positive samples (4.6% of all samples). Significantly higher proportion of microorganisms potentially dangerous to patients were isolated from sanitary facilities. Due to the potentially pathogenic microorganisms detected in the tested samples, the authors suggest that in the analyzed hospital, the areas requiring a specific level of microbiological purity should be designated and described, with [specifically] defined cleaning and disinfection protocols.
