RESUMO
BACKGROUND: Antibiotics are a strong risk factor for Clostridioides difficile infection (CDI), and CDI incidence is often measured as an important outcome metric for antimicrobial stewardship interventions aiming to reduce antibiotic use. However, risk of CDI from antibiotics varies by agent and dependent on the intensity (i.e., spectrum and duration) of antibiotic therapy. Thus, the impact of stewardship interventions on CDI incidence is variable, and understanding this risk requires a more granular measure of intensity of therapy than traditionally used measures like days of therapy (DOT). METHODS: We performed a retrospective cohort study to measure the independent association between intensity of antibiotic therapy, as measured by the antibiotic spectrum index (ASI), and hospital-associated CDI (HA-CDI) at a large academic medical center between January 2018 and March 2020. We constructed a marginal Poisson regression model to generate adjusted relative risks for a unit increase in ASI per antibiotic day. RESULTS: We included 35,457 inpatient encounters in our cohort. Sixty-eight percent of patients received at least one antibiotic. We identified 128 HA-CDI cases, which corresponds to an incidence rate of 4.1 cases per 10,000 patient-days. After adjusting for known confounders, each additional unit increase in ASI per antibiotic day is associated with 1.09 times the risk of HA-CDI (Relative Risk = 1.09, 95% Confidence Interval: 1.06 to 1.13). CONCLUSIONS: ASI was strongly associated with HA-CDI and could be a useful tool in evaluating the impact of antibiotic stewardship on HA-CDI rates, providing more granular information than the more commonly used days of therapy.
RESUMO
BACKGROUND: Little is known regarding differences between patients referred to hospice from different care locations. OBJECTIVE: The objective this study was to describe the associations between hospice referral locations and hospice patient and admission characteristics. RESEARCH DESIGN: Cross-sectional analysis of hospice administrative data. SUBJECTS: Adult (age older than 18 y) decedents of a national, for-profit, hospice chain across 19 US states who died between January 1, 2012, and December 31, 2016. MEASURES: Patients' primary hospice diagnosis, hospice length stay, and hospice care site. We also determined the frequency of opioid prescriptions with and without a bowel regimen on hospice admission. RESULTS: Among 78,647 adult decedents, the mean age was 79.2 (SD=13.5) years, 56.4% were female, and 69.9% were a non-Hispanic White race. Most hospice referrals were from the hospital (51.9%), followed by the community (21.9%), nursing homes (17.4%), and assisted living (8.8%). Cancer (33.6%) was the most prevalent primary hospice diagnosis; however, this varied significantly between referral locations (P<0.001). Similarly, home hospice (32.8%) was the most prevalent site; however, this also varied significantly between referral locations (P<0.001). More hospital-referred patients (55.6%) had a hospice length of stay <7 days compared with patients referred from nursing homes (30.3%), the community (28.9%), or assisted living (18.7%), P<0.001. Hospital-referred patients also had the lowest frequency (58.4%) of coprescribed opioids and bowel regimen on hospice admission compared with other referral locations. CONCLUSION: We observed significant differences in hospice patient and admission characteristics by referral location.

PURPOSE: Skilled nursing facility (SNF) residents are at increased risk for opioid-related harms. We quantified the frequency of opioid prescribing among patients discharged from an acute care hospital to SNFs. METHODS: This was a retrospective cohort study among adult (≥18 years) inpatients discharged from a quaternary-care academic referral hospital in Portland, OR to a SNF between January 1, 2017 and December 31, 2018. Our primary outcome was receipt of an opioid prescription on discharge to a SNF. Our exposures included patient demographics (eg, age, sex), comorbid illnesses, surgical diagnosis related group (DRG), receiving opioids on the first day of the index hospital admission, and inpatient hospital length of stay. RESULTS: Among 4374 patients discharged to a SNF, 3053 patients (70%) were prescribed an opioid on discharge. Among patients prescribed an opioid, 61% were over the age of 65 years, 50% were male, and 58% had a surgical Medicare severity diagnosis related group (MS-DRG). Approximately 70% of patients discharged to a SNF were prescribed an opioid on discharge, of which 68% were for oxycodone, and 52% were for ≥90 morphine milligram equivalents per day. Surgical DRG, diagnoses of cancer or chronic pain, last pain score, and receipt of an opioid on first day of the index hospital admission were independently associated with being prescribed an opioid on discharge to a SNF. CONCLUSION: Opioids were frequently prescribed at high doses to patients discharged to a SNF. Efforts to improve opioid prescribing safety during this transition may be warranted.

Posaconazole is used for prophylaxis for invasive fungal infections (IFIs) among patients with hematologic malignancies. We compared the incidence of breakthrough IFIs and early discontinuation between patients receiving delayed-release tablet and oral suspension formulations of posaconazole. This was a retrospective cohort study of patients receiving posaconazole between 1 January 2010 and 30 June 2016. We defined probable or proven breakthrough IFIs using the European Organization for Research and Treatment of Cancer (EORTC) criteria. Overall, 547 patients received 860 courses of posaconazole (53% received the oral suspension and 48% received the tablet); primary indications for prophylaxis were acute myeloid leukemia (69%), graft-versus-host disease (18%), and myelodysplastic syndrome (3%). There were no significant differences in demographics or indications between patients receiving the different formulations. The incidence and incidence rate of probable or proven IFIs were 1.6% and 3.2 per 10,000 posaconazole days, respectively. There was no significant difference in the rate of IFIs between suspension courses (2.8 per 10,000 posaconazole days) and tablet courses (3.7 per 10,000 posaconazole days) (rate ratio = 0.8, 95% confidence interval [CI] = 0.3 to 2.3). Of the 14 proven or probable cases of IFI, 8/14 had posaconazole serum concentrations measured, and the concentrations in 7/8 were above 0.7 µg/ml. Posaconazole was discontinued early in 15.5% of courses; however, the frequency of discontinuation was also not significantly different between the tablet (16.5%) and oral suspension (14.6%) formulations (95% CI for difference = -0.13 to 0.06). In conclusion, the incidence of breakthrough IFIs was low among patients receiving posaconazole prophylaxis and not significantly different between patients receiving the tablet formulation and those receiving the oral suspension formulation.

Extended-spectrum ß-lactamase (ESBL)-producing Enterobacteriaceae strains are increasing in prevalence worldwide. Carbapenem antibiotics are used as a first line of therapy against ESBL-producing Enterobacteriaceae We examined a cohort of critical care patients for gastrointestinal colonization with carbapenem-resistant ESBL-producing strains (CR-ESBL strains). We cultured samples from this cohort of patients for ESBL-producing Klebsiella spp. and Escherichia coli and then tested the first isolate from each patient for susceptibility to imipenem, doripenem, meropenem, and ertapenem. Multilocus sequence typing was performed on isolates that produced an ESBL and that were carbapenem resistant. Among all patients admitted to an intensive care unit (ICU), 4% were positive for an ESBL-producing isolate and 0.64% were positive for a CR-ESBL strain on surveillance culture. Among the first ESBL-producing E. coli and Klebsiella isolates from the patients' surveillance cultures, 11.2% were carbapenem resistant. Sequence type 14 (ST14), ST15, ST42, and ST258 were the dominant sequence types detected in this cohort of patients, with ST15 and ST258 steadily increasing in prevalence from 2006 to 2009. Patients colonized by a CR-ESBL strain were significantly more likely to receive antipseudomonal and anti-methicillin-resistant Staphylococcus aureus (anti-MRSA) therapy prior to ICU admission than patients colonized by carbapenem-susceptible ESBL-producing strains. They were also significantly more likely to have received a cephalosporin or a carbapenem antibiotic than patients colonized by carbapenem-susceptible ESBL-producing strains. In conclusion, in a cohort of patients residing in intensive care units within the United States, we found that 10% of the isolates were resistant to at least one carbapenem antibiotic. The continued emergence of carbapenem-resistant ESBL-producing strains is of significant concern, as infections due to these organisms are notoriously difficult to treat.

Carbapenem antibiotics are among the mainstays for treating infections caused by Acinetobacter baumannii, especially in the Northwest United States, where carbapenem-resistant A. baumannii remains relatively rare. However, between June 2012 and October 2014, an outbreak of carbapenem-resistant A. baumannii occurred in 16 patients from five health care facilities in the state of Oregon. All isolates were defined as extensively drug resistant. Multilocus sequence typing revealed that the isolates belonged to sequence type 2 (international clone 2 [IC2]) and were >95% similar as determined by repetitive-sequence-based PCR analysis. Multiplex PCR revealed the presence of a blaOXA carbapenemase gene, later identified as blaOXA-237 Whole-genome sequencing of all isolates revealed a well-supported separate branch within a global A. baumannii phylogeny. Pacific Biosciences (PacBio) SMRT sequencing was also performed on one isolate to gain insight into the genetic location of the carbapenem resistance gene. We discovered that blaOXA-237, flanked on either side by ISAba1 elements in opposite orientations, was carried on a 15,198-bp plasmid designated pORAB01-3 and was present in all 16 isolates. The plasmid also contained genes encoding a TonB-dependent receptor, septicolysin, a type IV secretory pathway (VirD4 component, TraG/TraD family) ATPase, an integrase, a RepB family plasmid DNA replication initiator protein, an alpha/beta hydrolase, and a BrnT/BrnA type II toxin-antitoxin system. This is the first reported outbreak in the northwestern United States associated with this carbapenemase. Particularly worrisome is that blaOXA-237 was carried on a plasmid and found in the most prominent worldwide clonal group IC2, potentially giving pORAB01-3 great capacity for future widespread dissemination.

Antimicrobial stewardship programs (ASPs) are an increasingly common intervention for optimizing antimicrobial therapy in healthcare settings. These programs aim to improve patient care and limit the emergence and spread of multidrug-resistant organisms by supporting prudent antimicrobial use. However, pressure from the current reimbursement climate necessitates that ASPs operate as cost-cutting programs rather than focus on patient outcomes. This has forced the research that is evaluating ASP interventions to concentrate heavily on economic outcomes. As the science of antimicrobial stewardship advances, it is essential that well-conducted evaluations, focused on patient and microbial outcomes, serve as the evidence base that directs optimal ASP intervention design and implementation. In this review, we provide guidance and recommendations for the design of studies to evaluate the impact of ASP interventions on patient and microbial outcomes.

The use of antibiotics is common in hospice care despite limited evidence that it improves symptoms or quality of life. Patients receiving antibiotics upon discharge from a hospital may be more likely to continue use following transition to hospice care despite a shift in the goals of care. We quantified the frequency and characteristics for receiving a prescription for antibiotics on discharge from acute care to hospice care. This was a cross-sectional study among adult inpatients (≥18 years old) discharged to hospice care from Oregon Health & Science University (OHSU) from 1 January 2010 to 31 December 2012. Data were collected from an electronic data repository and from the Department of Care Management. Among 62,792 discharges, 845 (1.3%) patients were discharged directly to hospice care (60.0% home and 40.0% inpatient). Most patients discharged to hospice were >65 years old (50.9%) and male (54.6%) and had stayed in the hospital for ≤7 days (56.6%). The prevalence of antibiotic prescription upon discharge to hospice was 21.1%. Among patients discharged with an antibiotic prescription, 70.8% had a documented infection during their index admission. Among documented infections, 40.3% were bloodstream infections, septicemia, or endocarditis, and 38.9% were pneumonia. Independent risk factors for receiving an antibiotic prescription were documented infection during the index admission (adjusted odds ratio [AOR]=7.00; 95% confidence interval [95% CI]=4.68 to 10.46), discharge to home hospice care (AOR=2.86; 95% CI=1.92 to 4.28), and having a cancer diagnosis (AOR=2.19; 95% CI=1.48 to 3.23). These data suggest that a high proportion of patients discharged from acute care to hospice care receive an antibiotic prescription upon discharge.

BACKGROUND: Hospice patients with end-stage liver disease (ESLD) have an increased risk of adverse drug events due to physiological changes and changes in pharmacokinetic and pharmacodynamic properties of medications; however, the use of opioid and central nervous system (CNS) depressant prescribing among patients with ESLD is prevalent. This study quantified the frequency and distribution of opioid and concomitant respiratory and CNS depressant prescribing among hospice patients with ESLD compared to other common hospice diagnoses of cancer, chronic obstructive pulmonary disorder (COPD), heart failure, and end-stage renal disease. METHODS: This was a cross-sectional study of adult (age 18 years or older) decedents of a large hospice chain. Patients included had a primary diagnosis of liver, cancer, cardiovascular, or respiratory disease. RESULTS: Among 119,424 hospice decedents, mean age of 77.9 years (standard deviation =13.5 years), 54.6% were female, and 58.9% were of a non-Hispanic white race. There was a similar frequency of prescribing a "scheduled" and "as needed [pro re nata (PRN)]" opioid or benzodiazepine in patients with ESLD compared to other common hospice diagnoses. In addition, there was a high prevalence of concurrent opioid and benzodiazepine prescriptions among patients with ESLD compared to cardiovascular and respiratory disease at admission (65.4% vs. 63.9% and 64.9%). Opioid requirements, oral morphine equivalent (OME) median [interquartile range (IQR)] at discharge were similar between cancer, liver, and respiratory disease, 120 OME [60-300], 120 OME [50-240], and 120 OME [50-240], respectively. CONCLUSIONS: We observed a high frequency of opioid and CNS depressant prescribing in a hospice patient population with ESLD which was similar to other common admitting hospice diagnoses.

Background: Clinical research focused on the burden and impact of Clostridioides difficile infection (CDI) often relies upon accurate identification of cases using existing health record data. Use of diagnosis codes alone can lead to misclassification of cases. Our goal was to develop and validate a multi-component algorithm to identify hospital-associated CDI (HA-CDI) cases using electronic health record (EHR) data. Methods: We performed a validation study using a random sample of adult inpatients at a large academic hospital setting in Portland, Oregon from January 2018 to March 2020. We excluded patients with CDI on admission and those with short lengths of stay (< 4 days). We tested a multi-component algorithm to identify HA-CDI; case patients were required to have received an inpatient course of metronidazole, oral vancomycin, or fidaxomicin and have at least one of the following: a positive C. difficile laboratory test or the International Classification of Diseases, Tenth Revision (ICD-10) code for non-recurrent CDI. For a random sample of 80 algorithm-identified HA-CDI cases and 80 non-cases, we performed manual EHR review to identify gold standard of HA-CDI diagnosis. We then calculated overall percent accuracy, sensitivity, specificity, and positive and negative predictive value for the algorithm overall and for the individual components. Results: Our case definition algorithm identified HA-CDI cases with 94% accuracy (95% Confidence Interval (CI): 88% to 97%). We achieved 100% sensitivity (94% to 100%), 89% specificity (81% to 95%), 88% positive predictive value (78% to 94%), and 100% negative predictive value (95% to 100%). Requiring a positive C. difficile test as our gold standard further improved diagnostic performance (97% accuracy [93% to 99%], 93% PPV [85% to 98%]). Conclusions: Our algorithm accurately detected true HA-CDI cases from EHR data in our patient population. A multi-component algorithm performs better than any isolated component. Requiring a positive laboratory test for C. difficile strengthens diagnostic performance even further. Accurate detection could have important implications for CDI tracking and research.
RESUMO
INTRODUCTION: Pharmacotherapy plays a critical role in the delivery of high-quality palliative care, but the intersection of palliative care and deprescribing has received little attention. AREAS COVERED: We conducted a scoping review of English language articles using PubMed to identify relevant publications between 1 January 2000 to 31 July 2022 using search terms of deprescribing, palliative care, end of life, and hospice. We summarize current definitions and developments in palliative care and deprescribing from both clinical and research perspectives. We highlight key challenges and outline proposed solutions and needed research. EXPERT OPINION: The future of deprescribing in palliative care requires the development and adoption of individualized approaches to medication management, including a reconsidered approach to communication about deprescribing. Evidence from high-quality clinical outcomes studies is lacking, and the field needs new approaches to coordination of care delivery. This review article will be of interest to both clinical and research-based pharmacists, physicians, and nurses interested in improving care for patients with serious illness.

CONTEXT: Palliative care (PC) is associated with improved quality of life, survival, and decreased healthcare use at the end of life among lung cancer patients. However, the specific elements of palliative care that may contribute to these benefits are unclear. OBJECTIVES: To evaluate the associations of PC and its setting of delivery with prescriptions of symptom management medications, advance care planning (ACP), hospice enrollment, and home health care (HHC) receipt. METHODS: Retrospective, cohort study of patients with advanced stage (IIIB/IV) lung cancer in the Veterans Health Administration (VA) diagnosed from 2007-2013; with follow-up through 2017. Propensity score methods were used with inverse probability of treatment weighting and logistic regression modeling, adjusting for patient and tumor characteristics. RESULTS: Among 23 142 patients, 57% received PC. Compared to non-receipt of PC, PC in any setting (inpatient or outpatient) was associated with increased prescriptions of pain medications (Adjusted Odds Ratio (aOR) = 1.63, 95% CI: 1.45-1.83), constipation regimen with pain medications (aOR = 2.04, 95% CI: 1.63-2.54), and antidepressants (aOR = 1.78, 95% CI: 1.52-2.09). PC was also associated with increased ACP (aOR = 1.52, 95% CI: 1.37-1.67) and hospice enrollment (aOR = 1.39, 95% CI:1.31-1.47), and decreased HHC (aOR = 0.79, 95% CI: 0.70-.90) compared to non-receipt of PC. Receipt of PC in outpatient settings was associated with increased prescriptions of pain medications (aOR = 2.54, 95% CI: 2.13-3.04) and antidepressants (aOR = 1.76, 95% CI: 1.46-2.12), and hospice enrollment (aOR = 2.09, 95% CI: 1.90-2.31) compared to receipt of PC in inpatient settings. CONCLUSIONS: PC is associated with increased use of symptom management medications, ACP, and hospice enrollment, especially when delivered in outpatient settings. These elements of care elucidate potential mechanisms for improved outcomes associated with PC and provide a framework for a primary palliative care approach among non-palliative care clinicians.

BackgroundTreatment with medications for opioid use disorder (MOUD) may improve hepatitis C virus (HCV) treatment outcomes by providing additional contact with health care professionals to support patient engagement. Objective: We describe a pharmacist-led HCV treatment model and assessed the effect of MOUD on adherence to direct-acting antivirals (DAAs) in an underserved patient population. Methods: This was a retrospective cohort study of adults (age≥18 years) treated for HCV infection with DAAs at a Federally Qualified Health Center in Portland, Oregon, between March 1, 2019, and March 16, 2020. Patients were followed to 12 weeks to assess adherence to DAAs by MOUD status. Results: Among 59 eligible patients, 16 (27%) were prescribed MOUD. Baseline characteristics were similar between patients who did and did not receive MOUD. Adherence to DAAs was overall high and not significantly different between the groups (median: 98.5% vs median: 100%; P = .06). Five patients missed at least one dose due to an adverse drug effect and two of these patients discontinued HCV therapy due to these effects. Conclusion: Adherence to HCV therapy was nearly 100% among underserved patients in a pharmacist-led HCV treatment model and did not differ by MOUD engagement.
RESUMO
PURPOSE: Direct oral anticoagulant (DOAC) medications have improved safety, efficacy, and laboratory monitoring requirements compared to warfarin. However, available data are limited on the frequency and clinical outcomes of pharmacist-driven warfarin-to-DOAC switches. We aimed to quantify the frequencies and rationale of warfarin-to-DOAC switches in an underserved population. We also assessed clinical outcomes and compliance with recommended laboratory monitoring after switches. METHODS: This retrospective cohort study included adult (age 18 years or older) patients on warfarin who were assessed by a clinical pharmacist for switch appropriateness to a DOAC. Study data were collected via manual chart review and included demographics, comorbid illnesses, switch status, the rationale for or against switching, incidence of thromboses and bleeds within 6 months of the switch assessment, and the time to the first complete blood count and renal and hepatic function tests after the switch. Statistical analysis utilized descriptive statistics, including the mean and SD, median and interquartile range, and frequencies and percentages. RESULTS: Among 189 eligible patients, 108 (57%) were switched from warfarin to a DOAC. The primary rationales for switching were less monitoring (64%) and labile international normalized ratio (32%). The main reason against switching was DOAC inappropriateness (53%), such as in morbid obesity (14%). Patient preference was commonly cited in both groups (54% and 36%, respectively). The overall incidence of thrombotic events (9%) and bleeds (15%) after switch assessment was low. Laboratory monitoring after switches was consistent with current recommendations. CONCLUSION: No increase in harm was observed 6 months after switch assessment when pharmacists at a family medicine clinic switched underserved patients from warfarin to DOACs.

Background: Little is known about antibiotic prescribing on hospice admission despite known risks and limited evidence for potential benefits. Objective: To describe the frequency and characteristics of patients prescribed antibiotics on hospice admission. Design: Cross-sectional study. Subjects: Adult (age ≥18 years) decedents of a national, for-profit hospice chain across 19 U.S. states who died between January 1, 2017 and December 31, 2019. Measures: The primary outcome was having an antibiotic prescription on hospice admission. Patient characteristics of interest were demographics, hospice referral location, hospice care location, census region, primary diagnosis, and infectious diagnoses on admission. We used multivariable logistic regression to quantify associations between study variables. Results: Among 66,006 hospice decedents, 6080 (9.2%) had an antibiotic prescription on hospice admission. Fluoroquinolones (22%) were the most frequently prescribed antibiotic class. Patients more likely to have an antibiotic prescription on hospice admission included those referred to hospice care from the hospital (adjusted odds ratio [aOR] 1.13, 95% confidence interval [CI] 1.00-1.29) compared with an assisted living facility, those receiving hospice care in a private home (aOR 3.85, 95% CI 3.50-4.24), nursing home (aOR 3.65, 95% CI 3.24-4.11), assisted living facility (aOR 4.04, 95% CI 3.51-4.64), or hospital (aOR 2.43, 95% CI 2.18-2.71) compared with inpatient hospice, and those with a primary diagnosis of liver disease (aOR 2.23, 95% CI 1.82-2.74) or human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (aOR 3.89, 95% CI 2.27-6.66) compared with those without these diagnoses. Conclusions: Approximately 9% of hospice patients had an antibiotic prescription on hospice admission. Patients referred to hospice from a hospital, those receiving care in a noninpatient hospice facility, and those with liver disease or HIV/AIDS were more likely to have an antibiotic prescription. These results may inform future antimicrobial stewardship interventions among patients transitioning to hospice care.

Background: High-quality hospice care is characterized by patient-centered care and shared decision making between patients, families, and health care workers. However, little is known regarding the frequency and characteristics of patient and family participation in medication decisions on transition to hospice care. Objective: To quantify the frequency and characteristics of patient and/or family participation in medication decisions. Subjects: Adult (age ≥18 years) patients discharged from Oregon Health & Science University Hospital (OHSU) to hospice care between January 1, 2010 and December 31, 2016. Design: Cross-sectional study. Measures: The primary outcome was documented patient and/or family participation. Patient or family participation was defined as documentation of patient or family member discussion surrounding medication decisions in the discharge summary. We used logistic regression to identify patient and admission characteristics associated with documentation of patient or family member participation in medication decisions. Results: Among 348 eligible patients, patient and/or family participation was documented in 22% of discharges to hospice care. Higher Charlson comorbidity index (adjusted odds ratio [aOR]: 1.09, 95% confidence interval [CI]: 1.01-1.17) and having a diagnosis of cancer (aOR: 1.99, 95% CI: 1.16-3.43) were associated with an increased documentation of patient or family member participation in medication decisions. Patients admitted to the intensive care unit were less likely to have patient/family member participation (aOR: 0.55, 95% CI: 0.32-0.94). Having a specialty palliative care consultation was not significantly associated with patient or family member participation in medication decisions (aOR: 0.77, 95% CI: 0.40-1.48). Conclusions: Patient or family participation in medication decisions was documented for only 22% patients on discharge to hospice care. Opportunities to improve participation likely include increasing knowledge and capacity regarding primary palliative care for all clinicians and implementation of specialized interventions for patients and families transitioning to hospice care from acute care settings.

OBJECTIVE: To describe interfacility transfer communication (IFTC) methods for notification of multidrug-resistant organism (MDRO) status in a diverse sample of acute-care hospitals. DESIGN: Cross-sectional survey. PARTICIPANTS: Hospitals within the Society for Healthcare Epidemiology of America (SHEA) Research Network (SRN). METHODS: SRN members completed an electronic survey on protocols and methods for IFTC. We assessed differences in IFTC frequency, barriers, and perceived benefit by presence of an IFTC protocol. RESULTS: Among 136 hospital representatives who were sent the survey, 54 (40%) responded, of whom 72% reported having an IFTC protocol in place. The presence of a protocol did not differ significantly by hospital size, academic affiliation, or international status. Of those with IFTC protocols, 44% reported consistent notification of MDRO status (>75% of the time) to receiving facilities, as opposed to 13% from those with no IFTC protocol (P = .04). Respondents from hospitals with IFTC protocols reported significantly fewer barriers to communication compared to those without (2.8 vs 4.3; P = .03). Overall, however, most respondents (56%) reported a lack of standardization in communication. Presence of an IFTC protocol did not affect whether respondents perceived IFTC protocols as having a significant impact on infection prevention or antimicrobial stewardship. CONCLUSIONS: Most respondents reported having an IFTC protocol, which was associated with reduced communication barriers at transfer. Standardization of protocols and clarity about expectations for sending and receipt of information related to MDRO status may facilitate IFTC and promote appropriate and timely infection prevention practices.

Trends in Staphylococcus aureus infections are not well described. To calculate incidence in overall S. aureus infection and invasive and noninvasive infections according to methicillin susceptibility and location, we conducted a 10-year population-based retrospective cohort study (1999-2008) using patient-level data in the Veterans Affairs Maryland Health Care System. We found 3,674 S. aureus infections: 2,816 (77%) were noninvasive; 2,256 (61%) were methicillin-resistant S. aureus (MRSA); 2,517 (69%) were community onset, and 1,157 (31%) were hospital onset. Sixty-one percent of noninvasive infections were skin and soft tissue infections; 1,112 (65%) of these were MRSA. Ten-year averaged incidence per 100,000 veterans was 749 (± 132 SD, range 549-954) overall, 178 (± 41 SD, range 114-259) invasive, and 571 (± 152 SD, range 364-801) noninvasive S. aureus infections. Incidence of all S. aureus infections significantly increased (p<0.001), driven by noninvasive, MRSA, and community-onset infections (p<0.001); incidence of invasive S. aureus infection significantly decreased (p<0.001).

Accessory gene regulator (agr) dysfunction in Staphylococcus aureus has been associated with a longer duration of bacteremia. We aimed to assess the independent association between agr dysfunction in S. aureus bacteremia and 30-day in-hospital mortality. This retrospective cohort study included all adult inpatients with S. aureus bacteremia admitted between 1 January 2003 and 30 June 2007. Severity of illness prior to culture collection was measured using the modified acute physiology score (APS). agr dysfunction in S. aureus was identified semiquantitatively by using a δ-hemolysin production assay. Cox proportional hazard models were used to measure the association between agr dysfunction and 30-day in-hospital mortality, statistically adjusting for patient and pathogen characteristics. Among 814 patient admissions complicated by S. aureus bacteremia, 181 (22%) patients were infected with S. aureus isolates with agr dysfunction. Overall, 18% of patients with agr dysfunction in S. aureus died, compared to 12% of those with functional agr in S. aureus (P = 0.03). There was a trend toward higher mortality among patients with S. aureus with agr dysfunction (adjusted hazard ratio [HR], 1.34; 95% confidence interval [CI], 0.87 to 2.06). Among patients with the highest APS (scores of >28), agr dysfunction in S. aureus was significantly associated with mortality (adjusted HR, 1.82; 95% CI, 1.03 to 3.21). This is the first study to demonstrate an independent association between agr dysfunction and mortality among severely ill patients. The δ-hemolysin assay examining agr function may be a simple and inexpensive approach to predicting patient outcomes and potentially optimizing antibiotic therapy.

BACKGROUND: HIV patients are at increased risk of development of infections and infection-associated poor health outcomes. We aimed to 1) assess the prevalence of USA300 community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) among HIV-infected patients with S. aureus bloodstream infections and. 2) determine risk factors for infective endocarditis and in-hospital mortality among patients in this population. METHODS: All adult HIV-infected patients with documented S. aureus bacteremia admitted to the University of Maryland Medical Center between January 1, 2003 and December 31, 2005 were included. CA-MRSA was defined as a USA 300 MRSA isolate with the MBQBLO spa-type motif and positive for both the arginine catabolic mobile element and Panton-Valentin Leukocidin. Risk factors for S. aureus-associated infective endocarditis and mortality were determined using logistic regression to calculate odds ratios (OR) and 95% confidence intervals (CI). Potential risk factors included demographic variables, comorbid illnesses, and intravenous drug use. RESULTS: Among 131 episodes of S. aureus bacteremia, 85 (66%) were MRSA of which 47 (54%) were CA-MRSA. Sixty-three patients (48%) developed endocarditis and 10 patients (8%) died in the hospital on the index admission Patients with CA-MRSA were significantly more likely to develop endocarditis (OR = 2.73, 95% CI = 1.30, 5.71). No other variables including comorbid conditions, current receipt of antiretroviral therapy, pre-culture severity of illness, or CD4 count were significantly associated with endocarditis and none were associated with in-hospital mortality. CONCLUSIONS: CA-MRSA was significantly associated with an increased incidence of endocarditis in this cohort of HIV patients with MRSA bacteremia. In populations such as these, in which the prevalence of intravenous drug use and probability of endocarditis are both high, efforts must be made for early detection, which may improve treatment outcomes.
