The outside temperature can influence the indoor temperature in climate-controlled health care units. That in turn may impact multidrug-resistant organisms (MRDOs), according to an article on the Healio website.
A study in Infection Control & Hospital Epidemiology, found a negative association between humidity and overall MDROs and gram-negative pathogens in units without climate control, and a positive association between temperature and overall MDROs, overall gram-positive pathogens, VRE and P. aeruginosa in the climate-controlled ICU.
Researchers found that temperature did not have a detectable impact on the incidence of MDROs in the non-climate-controlled wards.
For both the ICU and the non-climate-controlled wards, the study found that the inside temperature was significantly correlated with the temperature measured at a nearby meteorological station, indicating that weather conditions outside influenced indoor temperatures.
