Abstract
Background and objective: Bioaerosols are airborne particles which can cause a wide range of health effects including hospital and occupational infections, acute toxic effects, allergies and cancer. Hence, the aim of this study was the qualitative and quantitative evaluation of bioaerosol in different wards of Malayer city’s hospitals.
Material and methods: Sampling was conducted from twelve wards in two hospitals. Both bacterial and fungal sample were taken based on method of ACGIH bioaerosol committee. The samples were transported to blood agar and sabouraud medium then cultivated immediately. The type and number of colonies were determined in the laboratory then, the bioaerosol concentration was calculated in terms of cfu/m3.
Results: Overall, the maximum concentration of bacterial (21.27 cfu/m3) and fungal (66.49 cfu/m3) colonies were found in pediatric and CCU wards, respectively. The minimum concentration of both bacterial (8.74 cfu/m3) and fungal (2.18 cfu/m3) colonies were found in autoclaving ward. Staphylococ negative coagulase(33.76%), Micrococ species(16.23%) and Bacillus  species(15.58%) were found to be the most  common  organisms and, Penicillium spp. (50.9%), Cladosporium spp. (27.02%) and Aspergillus spp. (8.1%) were the most common fungal genus.
Conclusion: Except of a few cases, total concentration of bioaerosols was lower than the guideline concentration (30 cfu/m3) in the all wards. High concentrations of bioaerosols in some wards can be explained by some reasons such as wear and tear of buildings, improper ventilation, incomplete disinfection of wards and, the high number of patients and visitors.

Abbas Jahangiri, Mohammad Jahangiri,
Volume 18, Issue 2 (8-2019)
Abstract
Background: One of the most important ways to promote the quality and attractiveness of the journal for readers is the accurate evaluation of the published articles research methodology in the journals. The purpose of this study was to investigate the research methods of the articles published in the Journal of Hospital.
 
Materials & Methods: In this descriptive study, the research methods of all articles published in the Journal of Hospital from Fall 2016 to Fall 2018 including qualitative or quantitative, field or library research , data collection methods, data analysis software, location of research, nature of the research (descriptive or analytical, etc.), topics, as well as the number of authors were investigated.
 
Results: Data of 55.29% of papers was qualitative that was turned to quantitative, 47.06% of articles had descriptive-analytical method, and 68.24% of papers had employed a field research method. In addition, 51.76% of articles had used questionnaire and the SPSS software was used in 52.08% of the articles. The location of 45.45% of researches was in Tehran province. Finally, the subject of 23.53% of papers was policy making, planning, leadership, and management in hospitals.
 
Conclusion: Most authors of the articles have followed a very similar research method during the mentioned period. So, creating diversity in the nature of the researches, using other methods of collecting information rather than questionnaires, doing more library research, and not limiting the researches to Tehran province are the most important suggestions for future researchers.
