Clinicians' interpretation of thresholds in hospital antibiograms for gram-negative rod infections: A survey and contingent valuation study of hospitalists

Clinical guidelines suggest that hospital antibiograms are a key component when deciding empiric therapy, but little is known about how often clinicians use antibiograms and how they influence clinicians' empiric therapy decisions. We surveyed hospitalists at seven healthcare systems in the United States on their reported practices related to antibiograms and their hypothetical prescribing for four clinical scenarios associated with gram-negative rod pathogens. Each was given a randomly assigned antibiogram susceptibility percentage, and we used contingent valuation analysis to assess whether the antibiogram susceptibility percentage was associated with prescribing practices. Of the 193 survey responders, only 52 (26.9%) respondents reported using antibiograms more than monthly. Across all four clinical scenarios, there was no evidence that antibiogram susceptibility levels influenced antibiotic prescribing practices. With limited utilization and no evidence that they influenced practice, antibiograms may have a limited role in hospitalist care delivery for common gram-negative rod infections.

Propensity Score-Weighted Analysis of Postoperative Infection in Patients With and Without Preoperative Urine Culture

Importance

Although recent guidelines recommend against performance of preoperative urine culture before nongenitourinary surgery, many clinicians still order preoperative urine cultures and prescribe antibiotics for treatment of asymptomatic bacteriuria in an effort to reduce infection risk.

Objective

To assess the association between preoperative urine culture testing and postoperative urinary tract infection (UTI) or surgical site infection (SSI), independent of baseline patient characteristics or type of surgery.

Design, Setting, and Participants

This cohort study analyzed surgical procedures performed from January 1, 2017, to December 31, 2019, at any of 112 US Department of Veterans Affairs (VA) medical centers. The cohort comprised VA enrollees who underwent major elective noncardiac, nonurological operations. Machine learning and inverse probability of treatment weighting (IPTW) were used to balance the characteristics between those who did and did not undergo a urine culture. Data analyses were performed between January 2023 and January 2024.

Exposures

Performance of urine culture within 30 days prior to surgery.

Main Outcomes and Measures

The 2 main outcomes were UTI and SSI occurring within 30 days after surgery. Weighted logistic regression was used to estimate odds ratios (ORs) for postoperative infection based on treatment status.

Results

A total of 250 389 VA enrollees who underwent 288 858 surgical procedures were included, with 88.9% (256 753) of surgical procedures received by males and 48.9% (141 340) received by patients 65 years or older. Baseline characteristics were well balanced among treatment groups after applying IPTW weights. Preoperative urine culture was performed for 10.5% of surgical procedures (30 384 of 288 858). The IPTW analysis found that preoperative urine culture was not associated with SSI (adjusted OR [AOR], 0.99; 95% CI, 0.90-1.10) or postoperative UTI (AOR, 1.18; 95% CI, 0.98-1.40). In analyses limited to orthopedic surgery and neurosurgery as a proxy for prosthetic implants, the adjusted risks for UTI and SSI were also not associated with preoperative urine culture performance.

Conclusions and Relevance

This cohort study found no association between performance of a preoperative urine culture and lower risk of postoperative UTI or SSI. The results support the deimplementation of urine cultures and associated antibiotic treatment prior to surgery, even when using prosthetic implants.

Ageism scale for dental students (ASDS): A focus group review of content validity

PURPOSE/AIM

Improve content validity of the Ageism Scale for Dental Students (ASDS) and identify barriers to using the scale.

METHODS

Thematic analysis of transcripts of three purposively sampled focus groups of 1) geriatric dentistry specialists, 2) older adult dental patients, and 3) dental students.

RESULTS

Twenty-five participants engaged in focus groups. No new concepts to define ageism were identified. Experts found the scale acceptable and appropriate, yet they raised specific potential revisions to scale questions. Commonly reported themes already addressed by ASDS included the importance of tailoring decision-making to patient preference and not making assumptions about older adults' capacity or preferences for dental care. Barriers to identifying ageism or using the scale included experiential differences in interpreting scale items, cultural differences in attitudes towards older adults, and potential overlap with social determinants of health. Secondary findings include recommendations for older-adult focused training for dental students to provide positive, concrete guidance on caring for older adults.

CONCLUSION

There are opportunities to refine the Ageism Scale for Dental Students and to allow tailoring of the scale for specific national or cultural contexts.

Examining barriers to implementing a surgical-site infection bundle

BACKGROUND

Surgical-site infections (SSIs) can be catastrophic. Bundles of evidence-based practices can reduce SSIs but can be difficult to implement and sustain.

OBJECTIVE

We sought to understand the implementation of SSI prevention bundles in 6 US hospitals.

DESIGN

Qualitative study.

METHODS

We conducted in-depth semistructured interviews with personnel involved in bundle implementation and conducted a thematic analysis of the transcripts.

SETTING

The study was conducted in 6 US hospitals: 2 academic tertiary-care hospitals, 3 academic-affiliated community hospitals, 1 unaffiliated community hospital.

PARTICIPANTS

In total, 30 hospital personnel participated. Participants included surgeons, laboratory directors, clinical personnel, and infection preventionists.

RESULTS

Bundle complexity impeded implementation. Other barriers varied across services, even within the same hospital. Multiple strategies were needed, and successful strategies in one service did not always apply in other areas. However, early and sustained interprofessional collaboration facilitated implementation.

CONCLUSIONS

The evidence-based SSI bundle is complicated and can be difficult to implement. One implementation process probably will not work for all settings. Multiple strategies were needed to overcome contextual and implementation barriers that varied by setting and implementation climate. Appropriate adaptations for specific settings and populations may improve bundle adoption, fidelity, acceptability, and sustainability.

Survey of resuscitation practices at emergency medical service agencies in the U.S

Background

Survival for out-of-hospital cardiac arrest (OHCA) varies across emergency medical service (EMS) agencies. Yet, little is known about resuscitation response and quality improvement activities at EMS agencies. We describe herein a novel survey to EMS agencies in a U.S. registry for OHCA.

Methods

Using data from the Cardiac Arrest Registry to Enhance Survival (CARES), we identified 577 EMS agencies with ≥10 OHCA cases annually between 2015 and 2019 that remained active in CARES. We administered a survey to EMS directors regarding agency characteristics, cardiac arrest response, relationships with first responders and dispatchers, quality improvement activities and perceived barriers in the community.

Results

Of eligible EMS agencies, 470 (81.5%) completed the survey. The high completion rate was likely due to frequent personalized emails and phone calls, liaising with CARES state coordinators to encourage survey response, and multiple periodic drawings of an automated external defibrillator during the survey period for participating EMS agencies. The survey examined rates of resuscitation training modalities; use of resuscitation equipment and devices in the field; frequency of simulation; non-EMS stakeholder response to OHCA (dispatchers, fire, police); quality improvement; and community factors affecting bystander response to OHCA.

Conclusions

In this study design paper on the RED-CASO survey, we provide summary data on EMS agency characteristics in the U.S. Upon linkage to CARES patient-level data, this survey will provide critical insights into 'best practices' at EMS agencies with the highest OHCA survival rates as well as provide insights into current disparities in outcomes.

Cardiac Arrest Survival at Emergency Medical Service Agencies in Catchment Areas With Primarily Black and Hispanic Populations

Importance

Black and Hispanic patients are less likely to survive an out-of-hospital cardiac arrest (OHCA) than White patients. Given the central importance of emergency medical service (EMS) agencies in prehospital care, a better understanding of OHCA survival at EMS agencies that work in Black and Hispanic communities and White communities is needed to address OHCA disparities.

Objective

To examine whether EMS agencies serving catchment areas with primarily Black and Hispanic populations (Black and Hispanic catchment areas) have different rates of OHCA survival than agencies serving catchment areas with primarily White populations (White catchment areas).

Design, Setting, and Participants

A cohort study including adults with nontraumatic OHCA from January 1, 2015, to December 31, 2019, in the Cardiac Arrest Registry to Enhance Survival was conducted. Data analysis was conducted from August 17, 2022, to July 7, 2023.

Exposure

Emergency medical service agencies, categorized as working in catchment areas where the combination of Black and Hispanic residents made up more than 50% of the population or where White residents made up more than 50% of the population.

Main Outcomes and Measures

The unit of analysis was the EMS agency. The primary outcome was agency-level risk-standardized survival rates (RSSRs) to hospital admission for OHCA at each EMS agency, which were calculated using hierarchical logistic regression and compared between agencies serving Black and Hispanic and White catchment areas. Whether differences in OHCA survival were explained by EMS and first responder measures was evaluated with additional adjustment for these factors.

Results

Among 764 EMS agencies representing 258 342 OHCAs, 82 EMS agencies (10.7%) had a Black and Hispanic catchment area. Overall median age of the patients was 63.0 (IQR, 52.0-75.0) years, 36.1% were women, and 63.9% were men. Overall, the mean (SD) RSSR was 27.5% (3.6%), with lower survival at EMS agencies with Black and Hispanic catchment areas (25.8% [3.6%]) compared with agencies with White catchment areas (27.7% [3.5%]; P < .001). Among the 82 EMS agencies with Black and Hispanic catchment areas, a disproportionately higher number (32 [39.0%]) was in the lowest survival quartile, whereas a lower number (12 [14.6%]) was in the highest survival quartile. Additional adjustment for EMS response times, EMS termination of resuscitation rates, and first responder rates of initiating cardiopulmonary resuscitation or applying an automated external defibrillator before EMS arrival did not meaningfully attenuate differences in RSSRs between agencies with Black and Hispanic compared with White catchment areas (mean [SD] RSSRs after adjustment, 25.9% [3.3%] vs 27.7% [3.1%]; P < .001).

Conclusions and Relevance

Risk-standardized survival rates for OHCA were 1.9% lower at EMS agencies working in Black and Hispanic catchment areas than in White catchment areas. This difference was not explained by EMS response times, rates of EMS termination of resuscitation, or first responder rates of initiating cardiopulmonary resuscitation or applying an automated external defibrillator. These findings suggest there is a need for further assessment of these discrepancies.

Reporting Outcomes of Pediatric Intensive Care Unit Patients to Referring Physicians via an Electronic Health Record-Based Feedback System

BACKGROUND

 Many critically ill children are initially evaluated in front-line settings by clinicians with variable pediatric training before they are transferred to a pediatric intensive care unit (PICU). Because clinicians learn from past performance, communicating outcomes of patients back to front-line clinicians who provide pediatric emergency care could be valuable; however, referring clinicians do not consistently receive this important feedback.

OBJECTIVES

 Our aim was to determine the feasibility, usability, and clinical relevance of a semiautomated electronic health record (EHR)-supported system developed at a single institution to deliver timely and relevant PICU patient outcome feedback to referring emergency department (ED) physicians.

METHODS

 Guided by the Health Information Technology Safety Framework, we iteratively designed, implemented, and evaluated a semiautomated electronic feedback system leveraging the EHR in one institution. After conducting interviews and focus groups with stakeholders to understand the PICU-ED health care work system, we designed the EHR-supported feedback system by translating stakeholder, organizational, and usability objectives into feedback process and report requirements. Over 6 months, we completed three cycles of implementation and evaluation, wherein we analyzed EHR access logs, reviewed feedback reports sent, performed usability testing, and conducted physician interviews to determine the system's feasibility, usability, and clinical relevance.

RESULTS

 The EHR-supported feedback process is feasible with timely delivery and receipt of feedback reports. Usability testing revealed excellent Systems Usability Scale scores. According to physicians, the process was well-integrated into their clinical workflows and conferred minimal additional workload. Physicians also indicated that delivering and receiving consistent feedback was relevant to their clinical practice.

CONCLUSION

 An EHR-supported system to deliver timely and relevant PICU patient outcome feedback to referring ED physicians was feasible, usable, and important to physicians. Future work is needed to evaluate impact on clinical practice and patient outcomes and to investigate applicability to other clinical settings involved in similar care transitions.

Diagnosis Documentation of Critically Ill Children at Admission to a PICU

OBJECTIVES

Multidisciplinary PICU teams must effectively share information while caring for critically ill children. Clinical documentation helps clinicians develop a shared understanding of the patient's diagnosis, which informs decision-making. However, diagnosis-related documentation in the PICU is understudied, thus limiting insights into how pediatric intensivists convey their diagnostic reasoning. Our objective was to describe how pediatric critical care clinicians document patients' diagnoses at PICU admission.

DESIGN

Retrospective mixed methods study describing diagnosis documentation in electronic health records.

SETTING

Academic tertiary referral PICU.

PATIENTS

Children 0-17 years old admitted nonelectively to a single PICU over 1 year.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

One hundred PICU admission notes for 96 unique patients were reviewed. In 87% of notes, both attending physicians and residents or advanced practice providers documented a primary diagnosis; in 13%, primary diagnoses were documented by residents or advanced practice providers alone. Most diagnoses (72%) were written as narrative free text, 11% were documented as problem lists/billing codes, and 17% used both formats. At least one rationale was documented to justify the primary diagnosis in 91% of notes. Diagnostic uncertainty was present in 52% of notes, most commonly suggested by clinicians' use of words indicating uncertainty (65%) and documentation of differential diagnoses (60%). Clinicians' integration and interpretation of information varied in terms of: 1) organization of diagnosis narratives, 2) use of contextual details to clarify the diagnosis, and 3) expression of diagnostic uncertainty.

CONCLUSIONS

In this descriptive study, most PICU admission notes documented a rationale for the primary diagnosis and expressed diagnostic uncertainty. Clinicians varied widely in how they organized diagnostic information, used contextual details to clarify the diagnosis, and expressed uncertainty. Future work is needed to determine how diagnosis narratives affect clinical decision-making, patient care, and outcomes.

Strategies for the implementation of a nasal decolonization intervention to prevent surgical site infections within the Veterans Health Administration

As part of a multicenter evidence-based intervention for surgical site infection prevention, a qualitative study was conducted with infection control teams and surgical staff members at three Department of Veterans Affairs Healthcare Systems in the USA. This study aimed to identify strategies used by nurses and other facility champions for the implementation of a nasal decolonization intervention. Site visit observations and field notes provided contextual information. Interview data were analyzed with inductive and deductive content analysis. Interview data was mapped to the Expert Recommendations for Implementing Change (ERIC) compilation of implementation strategies. These strategies were then considered in the context of power and relationships as factors that influence implementation. We found that implementation of this evidence-based surgical site infection prevention intervention was successful when nurse champions drove the day-to-day implementation. Nurse champions sustained implementation strategies through all phases of implementation. Findings also suggest that nurse champions leveraged the influence of their role as champion along with their understanding of social networks and relationships to help achieve implementation success. Nurse champions consciously used multiple overlapping and iterative implementation strategies, adapting and tailoring strategies to stakeholders and settings. Commonly used implementation categories included: "train and educate stakeholders," "use evaluative and iterative strategies," "adapt and tailor to context," and "develop stakeholder interrelationships." Future research should examine the social networks for evidence-based interventions by asking specifically about relationships and power dynamics within healthcare organizations. Implementation of evidence-based interventions should consider if the tasks expected of a nurse champion fit the level of influence or power held by the champion.

Referral communication for pediatric intensive care unit admission and the diagnosis of critically ill children: A pilot ethnography

PURPOSE

The effect of communication between referring and accepting clinicians during patient transitions to the pediatric intensive care unit (PICU) on diagnostic quality is largely unknown. This pilot study aims to determine the feasibility of using focused ethnography to understand the relationship between referral communication and the diagnostic process for critically ill children.

MATERIALS AND METHODS

We conducted focused ethnography in an academic tertiary referral PICU by directly observing the referral and admission of 3 non-electively admitted children 0-17 years old. We also conducted 21 semi-structured interviews of their parents and admitting PICU staff (intensivists, fellows/residents, medical students, nurses, and respiratory therapists) and reviewed their medical records post-discharge.

RESULTS

Performing focused ethnography in a busy PICU is feasible. We identified three areas for additional exploration: (1) how information transfer affects the PICU diagnostic process; (2) how uncertainty in patient assessment affects the decision to transfer to the PICU; and (3) how the PICU team's expectations are influenced by referral communication.

CONCLUSIONS

Focused ethnography in the PICU is feasible to investigate relationships between clinician referral communication and the diagnostic process for critically ill children.
