Bioaerosol pollution in intensive-care unit of Dr. Wahidin Sudirohusodo Hospital Makassar: Morning and midday assessment

Objective: This research aims to determine the correlation of bioaerosol pollution with tem- perature, humidity, and lighting in the ICU for measurement in morning and midday. Methods: The research was an observational analytic with a cross-sectional study design con- ducted in Dr. Wahidin Sudirohusodo hospital. The sample of the research consisted of 8 ICU rooms. The data were analyzed using the Spearman test. Results: The total of bioaerosol in the morning ranged from 320---1885 CFU/m3 and the total of bioaerosol in midday ranged from 366---1895 CFU/m3. The result showed that the humidity factor correlated with the total of microbial (p = 0.006) but the temperature (p = 0.471) and lighting (p = 0.232) did not correlate with the total of bioaerosol for morning measurement. While the temperature, humidity and lighting factors correlated with the total of bioaerosol (p = 0.000) for midday measurement. Conclusion: The quality of bioaerosol correlates with temperature, humidity, and lighting. For further improvement designing well-built HVAC.
