A Quantitative Risk Analysis of the Health Effects of Construction Dust on Patients and Workers

Krupal Bhatt and John M. Nichols
Abstract— Aging of the world’s population, coupled with improvements in health care management and medical techniques continues to drive the increasing cost of medical treatment for the United States. A secondary and related cost is the Hospital Acquired Infections (HAI) that strike approximately 2 million patients in the USA each year. 100,000 patients will die each year from these secondary infections. A problem that has developed since the 1970s is a rise in secondary fungal infections for immune compromised patients, who are surviving longer. Fungal infections are nasty and very hard to treat, with a high mortality rate. There are several vectors or systems that move fungi into buildings, these include dust from construction sites and the outside space to the hospital. Careful control of dust is needed to minimize the risk to patients and workers during construction at hospitals. This paper represents part of a long running study at our university into dust movement into buildings. The goal is to develop a computational air, dust and fungi movement model for the problem to assist the statistical analysis of fungi movement rates into buildings. The objective of this paper’s research is to measure the flow of air through closed doors in a typical institutional building. The long term goal is to provide a mathematical model for air and dust movement through a closed door, to be part of the global model.

Index Terms— Airflow, fungi, hospital acquired infections.
