Warmer Weather Brings More Infections After Surgery


As the weather gets warmer, the risk of developing an infection at the site of a surgical wound increases, a brand-new study reports.

Surgical site infections are a leading cause of increased hospital readmissions, longer length of hospital stay, greater health care costs in addition to mortality.

Researchers used databases of hospital discharges across the United States to identify every adult hospitalization which has a surgical site infection by 1998 to 2011, in addition to tracked local temperature with data by the National Oceanic in addition to Atmospheric Administration. The study, in Infection Control & Hospital Epidemiology, included more than 55 million hospitalizations in more than 2,500 hospitals.

Compared with January, the risk of being admitted to a hospital for a surgical site infection rose steadily by 9 percent higher in February to 21 percent higher in August. Then the risk declined in each month through December.

After controlling for many various other variables, the researchers found in which for every 5-degree Fahrenheit increase in average monthly temperature, the risk of hospital admission for a surgical site infection increased by 2.1 percent.

Why in which happens is usually not clear.

“There are various other skin in addition to soft tissue infections in which are seasonal,” said the senior author, Dr. Philip M. Polgreen, an associate professor of medicine at the University of Iowa, “in addition to there have been reports in which the bacterial colonization of the skin may change by season to season. yet we need more investigation to help us understand the mechanisms.”
