Interhospital variability in health care-associated infections and payments after durable ventricular assist device implant among Medicare beneficiaries.
The purpose of this study was to examine differences in durable ventricular assist device implantation infection rates and associated costs across hospitals. The researchers utilized clinical data for 8,688 patients who received primary durable ventricular assist devices from the Society of Thoracic Surgeons Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs) hospitals (n = 120) and merged that data with post-implantation 90-day Medicare claims. The primary outcome included infections within 90 days of implantation and Medicare payments. The study found that 27.8% of patients developed 3982 identified infections. The median adjusted incidence of infections (per 100 patient-months) across hospitals was 14.3 and differed according to hospital. Total Medicare payments from implantation to 90 days were 9.0% more in high versus low infection tercile hospitals. The researchers concluded that health-care-associated infection rates post durable ventricular assist device implantation varied according to hospital and were associated with increased 90-day Medicare expenditures.

Association between care fragmentation and total spending after durable left ventricular device implant: a mediation analysis of health care-associated infections within a national Medicare-Society of Thoracic Surgeons INTERMACS linked dataset.
The purpose of this study was to examine the relationship between care fragmentation and total spending for durable left ventricular assisted device (LVAD) implant, and whether this relationship is mediated by infections. The researchers developed a measure of care fragmentation based on the number of shared medical professionals providing care to 4,987 Medicare beneficiaries undergoing LVAD implantation. The study found that the indirect effect of care fragmentation, through infections, was positive and statistically significant. The researchers concluded that higher care fragmentation associated with durable LVAD implantation is related with a greater incidence of infections and higher Medicare beneficiary payments.

Economic evaluation of quality improvement interventions to prevent catheter-associated urinary tract infections in the hospital setting: a systematic review.
This systematic review looked at economic evaluations of quality improvement (QI) interventions to reduce rates of catheter-associated urinary tract infections (CAUTIs). A literature review was conducted for conference abstracts and studies from January 2000 to October 2020. Dual reviewers assessed study design, effectiveness, costs and study quality for eligibility. The reviewers performed a cost-consequence analysis from the hospital perspective, estimating the incidence rate ratio and increment net cost/savings per hospital over 3 years for each eligible study. Fifteen unique economic evaluations were eligible, and 12 studies were amenable to standardization. QI interventions were associated with a 43% decline in infections and wide ranges of net costs relative to usual care.

Association of postoperative infections after fractures with long-term income among adults.
This retrospective cohort study evaluated the association between postoperative infection in patients with surgically treated fractures and long-term income loss. Out of 11,673 adults who underwent surgery to treat fractures of the extremities or pelvis from 2003-2016, a total of 3.5% had a postoperative infection. These infections were associated with a $6080 annual decrease in household income in the 6 years after injury. There was a 6.6% increase in the risk of catastrophic wage loss within 2 years of the fracture and a 45% increase in the odds of receiving Social Security benefits. However, postoperative infections were not associated with an increase in the value of the Social Security benefits received.

Attributable cost of healthcare-associated methicillin-resistant Staphylococcus aureus infection in a long-term care center.
The purpose of this study was to estimate the attributable cost of methicillin-resistant Staphylococcus aureus (MRSA) healthcare-associated infections in long-term care centers (LTCCs) within the Department of Veterans Affairs. Findings showed a significant increase in the odds of being transferred to an acute care facility and in acute care costs. These findings of high cost and increased risk of transfer from LTCC to acute care are important because they highlight the substantial clinical and economic impact of MRSA infections in this population.

Costs of ambulatory pediatric healthcare-associated infections: Central-line-associated bloodstream infection (CLABSIs), catheter-associated urinary tract infection (CAUTIs), and surgical site infections (SSIs).
Ambulatory healthcare-associated infections (HAIs) occur frequently in children and are associated with morbidity. Less is known about ambulatory HAI costs. This retrospective case control study estimated additional costs associated with pediatric ambulatory central-line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTI), and surgical site infections (SSIs) following ambulatory surgery. The authors concluded that ambulatory HAI in pediatric patients were associated with significant additional costs.

A comparison of estimated cost savings from potential reductions in hospital-acquired conditions to levied penalties under the CMS Hospital-Acquired Condition Reduction Program.
The Hospital-Acquired Condition Reduction Program (HACRP) from the Centers for Medicare & Medicaid Services (CMS) reduces Medicare payments to hospitals with high rates of hospital-acquired conditions (HACs) by 1% each year. It is not known how the savings accruing to CMS from such penalties compare to savings resulting from a reduction in HACs driven by this program. This study compared the reported savings to CMS from financial penalties levied under the HACRP with savings resulting from potential reductions in HACs.

The potential economic value of sputum culture use in patients with community-acquired pneumonia and healthcare-associated pneumonia.
Researchers developed a decision model to determine the economic and clinical value of using sputum cultures in the treatment of community-acquired pneumonia (CAP) and healthcare-associated pneumonia (HCAP) from the hospital perspective under various conditions. They found that, overall, obtaining sputum cultures does not provide significant clinical or economic benefits for CAP or HCAP patients; however, it can reduce costs and shorten overall length of stay under some circumstances. They recommended that clinicians consider their local conditions when making decisions about sputum culture use.

Cost-effectiveness of pre-operative Staphylococcus aureus screening and decolonization.
In this study, the investigators developed a decision analytic model to evaluate the impact of a preoperative Staphylococcus aureus decolonization bundle on surgical site infections (SSIs), health-care-associated costs (HCACs), and deaths due to SSI. The investigators predict that the treat-all strategy would be the most effective and cost-saving strategy for preventing SSIs. However, they concluded that because this strategy might select more extensively for mupirocin-resistant S. aureus and cause more medication adverse effects than the test-and-treat approach or the SOC, additional studies are needed to define its comparative benefits and harms.

Clinical and economic benefits of antimicrobial stewardship programs in hemodialysis facilities: a decision analytic model.
In this study, the authors developed a decision analytic model of antimicrobial use on the clinical and economic consequences of implementing a nationwide antimicrobial stewardship program in outpatient dialysis facilities. The authors found that the model suggested that implementation of antimicrobial stewardship programs in outpatient dialysis facilities would result in substantial reductions in infections caused by multidrug-resistant organisms and C. difficile, infection-related deaths, and costs.

Association between postoperative pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery.
Postoperative pneumonia is the most common healthcare-associated infection in cardiac surgical patients, yet their impact across a 90-day episode of care remains unknown. The objective of this study was to examine the relationship between pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery. The investigators concluded that postoperative pneumonia was associated with significantly higher 90-day episode payments and inferior outcomes at the patient and hospital level.

Economic evaluation of quality improvement interventions for bloodstream infections related to central catheters: a systematic review.
The authors systematically reviewed economic evaluations of QI interventions designed to prevent central-line-associated bloodstream infections (CLABSI) and catheter-related bloodstream infections (CRBSI) in acute care hospitals. They concluded that interventions related to central venous catheters were, on average, associated with 57% fewer bloodstream infections and substantial savings to hospitals. Larger initial investments may be associated with greater savings.

Impact of the Centers for Medicare and Medicaid services hospital-acquired conditions policy on billing rates for 2 targeted healthcare-associated infections.
The 2008 Centers for Medicare & Medicaid Services (CMS) hospital-acquired conditions policy limited additional payment for conditions deemed reasonably preventable. This study examined whether this policy was associated with decreases in billing rates for 2 targeted conditions, vascular catheter-associated infections (VCAI) and catheter-associated urinary tract infections (CAUTI). The CMS policy appears to have been associated with immediate reductions in billing rates for VCAI and CAUTI, followed by a slight decreasing trend or leveling-off in rates.

Cost savings of universal decolonization to prevent intensive care unit infection: implications of the REDUCE MRSA trial.
The researchers estimated the incremental effect on healthcare costs associated with targeted decolonization and universal decolonization compared with screening and isolation, which is considered the current standard of care. They found that a strategy of universal decolonization for patients admitted to the ICU would both reduce bloodstream infections and like reduce healthcare costs when compared to other strategies.
