I have seen the third TJC survey report in a month that resulted in a 45 day conditional follow up survey. A CMS condition level citation was written. The problem was negative airflow in operating rooms that should be positive, and positive airflow in decontamination rooms that should be negative. They mean BUSINESS. It is expected that cases are canceled if the airflow is incorrect. Most hospitals only measure annually. Obviously the airflows should be measured almost on a daily basis.
