Not busting your balls but can you point me to the actual study that proves this beyond doubt? Also you know in that picture they are cutting people open right? Even though they try and protect the patient from contamination some still get infections correct?
I would like to see a study of battlefield wound infection rates vs hospital surgical infection rates. The folks patching soldiers up wear no mask and they are normally in a less than sterile environment. Someone somewhere must have that data.
Just because something has been done forever does not mean it's correct.
USN Study;
Objective:
To describe risks for, and microbiology and antimicrobial resistance patterns of, war trauma associated infections from Operation Iraqi Freedom.
Background: The invasion of Iraq resulted in casualties from high-velocity gunshot, shrapnel, and blunt trauma injuries as well as burns. Infectious complications of these unique war trauma injuries have not been described since the 1970s.
Methods: Retrospective record review of all trauma casualties 5 to 65 years of age evacuated from the Iraqi theatre to U.S. Navy hospital ship, USNS Comfort March to May 2003.War trauma-associated infection was defined by positive culture from a wound or sterile body fluid (ie, blood, cerebrospinal fluid) and at least two of the following infection-associated signs/symptoms: fever, dehiscence, foul smell, peri-wound erythema, hypotension, and leukocytosis. A comparison of mechanisms of injury, demographics, and clinical variables was done using multivariate analysis.
Results: Of 211 patients, 56 met criteria for infection. Infections were more common in blast injuries, soft tissue injuries, >3 wound sites, loss of limb, abdominal trauma, and higher Injury Severity Score (ISS). Wound infections accounted for 84% of cases, followed by bloodstream infections (38%). Infected were more likely to have had fever prior to arrival, and had higher probability of ICU admission and more surgical procedures. Acinetobacter species (36%) were the predominant organisms followed by
Escherichia coli and Pseudomonas species (14% each).
US Army Study;
Conclusions: One-third of combat casualties from Iraq and Afghanistan develop infections during their initial hospitalization. Amputations, blood transfusions, and overall injury severity are associated with risk of infection, whereas more easily modifiable factors such as early operative intervention or antibiotic administration are not.
From Johns Hopkins: Skin is a natural barrier against infection. Even with many precautions and protocols to prevent infection in place, any surgery that causes a break in the skin can lead to an infection. Doctors call these infections surgical site infections (SSIs) because they occur on the part of the body where the surgery took place. If you have surgery, the chances of developing an SSI are about 1% to 3%.
Navy Battlefield triage infection rate : 56 out of 211 = 26% (Those 56 had to fit a particular criteria there may be more if the particular criteria for this study is oped up)
Army Battlefield triage infection rate: 33%
Hospital: 1-3%
Not sure how much masks have to do with it but those are the numbers.
