Intravenous to Oral Antibiotic Switch Therapy among Patients Hospitalized with Community-Acquired Pneumonia (Thomas Higgins, Sarah Haessler and Peter Lindenauer) All Scholarly Works (2023)

Background: Community-acquired pneumonia (CAP) is a leading cause of hospital admissions and antimicrobial use. Clinical practice guidelines recommend switching from intravenous (IV) to oral antibiotics once patients are clinically stable. Methods: We conducted a retrospective ...

Characterizing burnout among healthcare epidemiologists in the early phases of the COVID-19 pandemic: A study of the SHEA Research Network (Sarah Haessler) All Scholarly Works (2023)

A multisite research team proposed a survey to assess burnout among healthcare epidemiologists. Anonymous surveys were disseminated to eligible staff at SRN facilities. Half of the respondents were experiencing burnout. Staffing shortages were a key ...

Use of expert consensus to develop a shared list of procedures with potential for aerosol generation during the coronavirus disease 2019 (COVID-19) pandemic (Sarah Haessler) All Scholarly Works (2023)

The coronavirus disease 2019 (COVID-19) pandemic highlighted the lack of agreement regarding the definition of aerosol-generating procedures and potential risk to healthcare personnel. We convened a group of Massachusetts healthcare epidemiologists to develop consensus through ...

Back to the future: Redefining "universal precautions" to include masking for all patient encounters (Sarah Haessler) All Scholarly Works (2023)

Despite recent guidance from the Centers for Disease Control and Prevention (CDC) allowing institutions to relax in-facility masking strategies and due to our evolving understanding of respiratory pathogen transmission during the coronavirus disease 2019 (COVID-19) ...

Derivation and validation of a risk assessment model for drug-resistant pathogens in hospitalized patients with community-acquired pneumonia (Sarah Haessler, Peter Lindenauer and Thomas Higgins) All Scholarly Works (2022)

Objective: To derive and validate a model for risk of resistance to first-line community-acquired pneumonia (CAP) therapy. Design: We developed a logistic regression prediction model from a large multihospital discharge database and validated it versus ...

Influenza Testing and Treatment Among Patients Hospitalized With Community-Acquired Pneumonia (Thomas Higgins, Sarah Haessler and Peter Lindenauer) All Scholarly Works (2022)

Background: Influenza is a leading cause of community-acquired pneumonia (CAP), and results of influenza tests can direct therapy. However, among adults hospitalized with CAP, little is known about the frequency and timing of influenza testing, ...

Association of fluoroquinolones or cephalosporin plus macrolide with Clostridioides difficile infection (CDI) after treatment for community-acquired pneumonia (Peter Lindenauer and Sarah Haessler) All Scholarly Works (2022)

Objective: Clostridioides difficile infection (CDI) is the most common cause of gastroenteritis, and community-acquired pneumonia (CAP) is the most common infection treated in hospitals. American Thoracic Society (ATS)/Infectious Diseases Society of America (IDSA) CAP guidelines ...

Etiology, Treatments, and Outcomes of Patients With Severe Community-Acquired Pneumonia in a Large U.S. Sample (Sarah Haessler and Peter Lindenauer) All Scholarly Works (2022)

Objectives: Compare the clinical practice and outcomes in severe community-acquired pneumonia (sCAP) patients to those in non-sCAP patients using guideline-defined criteria for sCAP. Design: Retrospective observational cohort study. Setting: One hundred seventy-seven U.S. hospitals within ...

Monitored COVID-19 mRNA vaccine second doses for people with adverse reactions after the first dose (Megan Gallagher, Sarah Haessler, Elizabeth Pecoy-Whitcomb, et al.) All Scholarly Works (2022)

Background: After Emergency Use Authorization of the coronavirus disease 2019 (COVID-19) vaccines, guidance was provided by the Centers for Disease Control and Prevention that persons with an immediate allergic reaction to a messenger RNA (mRNA) ...

Preparing nursing homes for a second wave of coronavirus disease 2019 (COVID-19) (Sarah Haessler) All Scholarly Works (2021)

The coronavirus disease 2019 (COVID-19) pandemic-Looking back and looking forward (Sarah Haessler) All Scholarly Works (2021)

Assessing the healthcare epidemiology environment-A roadmap for SHEA's future (Sarah Haessler) All Scholarly Works (2021)

Bacterial coinfection in influenza pneumonia: Rates, pathogens, and outcomes (Sarah Haessler) All Scholarly Works (2021)

Background: Evidence from pandemics suggests that influenza is often associated with bacterial coinfection. Among patients hospitalized for influenza pneumonia, we report the rate of coinfection and distribution of pathogens, and we compare outcomes of patients ...

Respiratory viral testing and antibacterial treatment in patients hospitalized with community-acquired pneumonia (Sarah Haessler) All Scholarly Works (2020)

Objective: Viruses are more common than bacteria in patients hospitalized with community-acquired pneumonia. Little is known, however, about the frequency of respiratory viral testing and its associations with antimicrobial utilization. Design: Retrospective cohort study. Setting: ...

Risk factors, management, and outcomes of legionella pneumonia in a large nationally-representative sample (Joshua Allgaier, Tara Lagu and Sarah Haessler) All Scholarly Works (2020)

Background: ATS/IDSA guidelines recommend against routine Legionella pneumophila testing but that hospitalized patients with community-acquired pneumonia (CAP) receive empiric treatment covering Legionella. Testing, empiric treatment, and outcomes for patients with Legionella have not been well ...

Whither immunity? The search for effective, durable immunity to coronavirus disease 2019 (COVID-19) (Sarah Haessler) All Scholarly Works (2020)

Assessment of the Accuracy of Using ICD-9 Diagnosis Codes to Identify Pneumonia Etiology in Patients Hospitalized With Pneumonia (Thomas Higgins, Sarah Haessler and Peter Lindenauer) All Scholarly Works (2020)

Importance: Administrative databases may offer efficient clinical data collection for studying epidemiology, outcomes, and temporal trends in health care delivery. However, such data have seldom been validated against microbiological laboratory results. Objective: To assess the ...

Stopping the Routine Use of Contact Precautions for Management of MRSA and VRE at Three Academic Medical Centers: An Interrupted Time Series Analysis (Sarah Haessler and Mary Ellen Scales) All Scholarly Works (2020)

Background: Contact precautions (CP) are a widely adopted strategy to prevent cross-transmission of organisms, commonly methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE). Some hospitals have discontinued CP for patients with MRSA or VRE; however, ...
