The microorganisms that cause nosocomial infections have been well cataloged and the infections they cause are fairly well understood, but the traditional solutions, cleaning, scrubbing, disinfectants, ventilation, filtration, management and procedural controls, etc., have failed to completely eliminate the problem.Kowalski, Wladyslaw. Hospital Airborne Infection Control. CRC Press, 12/2011.

Hospital Acquired Conditions

HACs

What is going on in the air?

HACsSurgical Site Infections are often the most problematic and fatal type infection that can occur in hospital settings.

Many SSIs are thought to be transmitted only by direct contact, either hand to patient or hand to equipment, or equipment to patient, but this view over looks the fact that both hands and equipment may pick up contamination from elsewhere, and that may include settling from the air.

Once settled, they may be resuspended by activity.Although direct contact is regarded as being the primary mode of contamination of surgical sites, airborne transmission can occur. Mangram etal. 1999

Breaking the Cycle

Section 5001(c) of Deficit Reduction Act of 2005 requires the Secretary to identify conditions that are:  (a) high cost or high volume or both, (b) result in the assignment of a case to a DRG that has a higher payment when present as a secondary diagnosis, and (c) could reasonably have been prevented through the application of evidence‑based guidelines.

On July 31, 2008, in the Inpatient Prospective Payment System (IPPS) Fiscal Year (FY) 2009 Final Rule, CMS included 10 categories of conditions that were selected for the HAC payment provision. Payment implications began October 1, 2008, for these Hospital Acquired Conditions.http://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/HospitalAcqCond/Hospital-Acquired_Conditions.html

The Affordable Care Act of 2010 established the Hospital VBP Program, which applies to payments beginning in FiscalYear (FY) 2013, on or after October 1, 2012, and affects payment for inpatient stays in 2,985 hospitals across the country.

Legislation

What CMS is doing: Since October 1, 2007, hospitals have been required to report on their Medicare claims if any of the first eight selected conditions were present at the time the patient was admitted to the hospital, and beginning October 1, 2008, will have to report on the remaining conditions as well.  If at discharge, there is a selected condition that was either not identified by the hospital as present on admission, or could not be identified based on data and clinical judgment at admission, it is considered hospital-acquired. 

To encourage hospitals to avoid hospital-acquired conditions, beginning October 1, 2008, Medicare will no longer pay hospitals at a higher rate for the increased costs of care that result when a patient is harmed by one of the listed conditions if it was hospital-acquired.  Medicare prohibits the hospital from billing the beneficiary for the difference between the lower and higher payment rates.

Medicare will pay for physician and other covered items or services that are needed to treat the hospital-acquired condition, including the costs of post-acute care that would not have been needed for the patient’s initial medical problem, but are needed because of the hospital-acquired condition.http://www.cms.gov/apps/media/press/factsheet.asp

The Hospital Value-Based Purchasing (VBP) Program is a Centers for Medicare & Medicaid Services (CMS) initiative that rewards acute-care hospitals with incentive payments for the quality of care they provide to people with Medicare. The Affordable Care Act of 2010 established the Hospital VBP Program, which applies to payments beginning in Fiscal Year (FY) 2013, on or after October 1, 2012, and affects payment for inpatient stays in 2,985 hospitals across the country

Facts

Average cost of a Healthcare Acquired Conditionin the US, the annual economic impact of HAIs was approximately $6.5 billion in 2004 . Recently Zimlichman and colleagues  conducted a systematic review of the literature for the years 1986 through 2013 for an updated estimate of costs associated with the most significant and targetable HAIs in the US. These were CLABSI, VAP, SSI, CR-UTI, and C. difficile infection (CDI). On a pair case basis, CLABSI were found to be the most costly at $45,814 (95% CI, $30,919-$65,245), followed by VAP at $40,144 (95% CI,$36,286-$44,220), SSI at $20,785 (95% CI, $18,902-$22,667), CDI at $11,285 (95% CI, $9,118-$13,574), and CR-UTI at $896 (95% CI, $603-$1,189).

Based on 2009 data where approximately 34.7 million adults received inpatient care in US hospitals (totaling 165 million patient days), the total annual cost of the 5 infections was $9.8 billion (95% CI, $ 8.3-11.5 billion) with SSI and CDI being the most frequent (36% and 30% respectively).

Costs

Reimbursement CMS new “value” vs. old “fee-based” reimbursement

DEPARTMENT OF HEALTH AND HUMAN SERVICES Centers for Medicare & Medicaid Services Hospital Value-Based Purchasing Program

The Hospital Value-Based Purchasing (VBP) Program is a Centers for Medicare & Medicaid Services (CMS) initiative that rewards acute-care hospitals with incentive payments for the quality of care they provide to people with Medicare. How Does Hospital Value-Based Purchasing Work? CMS rewards hospitals based on the quality of care provided to Medicare patients, how closely best clinical practices are followed, and how well hospitals enhance patients’ experiences of care during hospital stays. Hospitals are no longer paid solely based on the quantity of services they provide.

The Affordable Care Act of 2010 established the Hospital VBP Program, which applies to payments beginning in Fiscal Year (FY) 2013, on or after October 1, 2012, and affects payment for inpatient stays in 2,985 hospitals across the country. Under the Hospital VBP Program, Medicare makes incentive payments to hospitals based on either: 1) How well they perform on each measure, or 2) How much they improve their performance on each measure compared to their performance during a baseline period.

“Changing the way we pay hospitals will improve the quality of care for seniors and save money. Under this initiative, Medicare will reward hospitals that provide high quality care and keep their patients healthy. It’s an important part of our work to improve the health of our nation and drive down costs.” Kathleen Sebelius, Secretary of the U.S. Department of Health and Human Services (HHS) April 29, 2011 ICN 907664 March 20132

Reducing HAC occurrences

will impact “value” of care

If we consider the fact that most fomite contamination of surfaces, especially horizontal surfaces like floors, must arrive via the air, then we must admit that airborne transport plays a role in surface contamination.Kowalski, Wladyslaw. Hospital Airborne Infection Control. CRC Press, 12/2011.

Biological Air Cleaning – Settling Rates

Hospital VentilationIt is assumed that hospital ventilation systems are designed in accordance with appropriate guidelines and codes, and are not subject to internal mold growth and excessive condensation, and that they do not have outside air intakes too close to roof exhausts or cooling towers.

Dilution Ventilation removes all airborne pathogens at approximately equal rates if complete mixing occurs, but some larger microbes and spores may settle out and remain on surfaces. Ventilation air may also add microbes from outdoor air if there is no filtration or filtration is inadequate.

Filtration:Breakthrough

Integrity of Design

HEPA filtration effectiveness has been examined to determine the most penetrating microorganisms. For a single pass through a HEPA 99.97% filter, the number of penetrations per million for each microbe in Table 1 was calculated. Figure 9 shows the results of this analysis, where only those microbes that experienced penetration above about 30 per million are listed. All of the microbes between H. influenzae and Varicella experienced penetrations greater than 1 in 10,000. This may be insignificant, especially for a single pass through the filter, but it depends on the airborne concentration and the infective dose for each microorganism.

The infective dose for M. tuberculosis is 1-10 bacilli.

An intriguing aspect of Figure 9 is that almost all of the most penetrating microorganisms are agents of nosocomialinfections.

1. Genesis Air PCO units either as standalone or in AHUs reduce the levels of CFUs in the air stream and a space.

2. Genesis Air units in a single pass application at a removal rate of 99.9% for MRSA and 88.7% for Tuberculosis are a must for areas where high CFU levels would lead to higher infection and mortality rates from TB, MRSA and other nosocomial infections.

3. In either single pass or in recirculating systems Genesis Air equipment alone (without filtration) will reduce bio-aerosol microbial contaminants.
