Integration of Diagnostic Lung Ultrasound Into Clinical Practice by Hospitalists in an Academic Medical Center: A Retrospective Chart Review.

Background Point-of-care lung ultrasound (LUS) is a guideline-recommended imaging modality that has been shown to be more accurate than chest radiography for multiple causes of dyspnea. This study was conducted to understand the impact of LUS on real-world clinical decision-making among hospitalists. Methods  A retrospective chart review was conducted of patients who received a LUS while hospitalized at a quaternary care academic medical center between July 2020 and June 2022. Data was extracted from the electronic health record (EHR) into a standardized REDCap form. Cases were defined as patients who had received a LUS that (1) had images archived and accessible to viewing through the EHR and (2) had an imaging report documented in the EHR. Results Of the 820 LUSs reviewed, 297 (36.2%) were performed to evaluate for appropriateness of thoracentesis, 205 (25%) for diagnosing or monitoring of pneumonia related to COVID-19, 169 (20.6%) for volume status assessment, 136 (16.6%) for worsening respiratory status, 114 (13.9%) for monitoring pleural effusions, 64 (7.8%) for diagnosing or monitoring of pneumonia not related to COVID-19, and 12 (1.5%) for monitoring of diuresis. Documentation was sufficient to determine clinical decision-making in 730 (89%) of LUSs reviewed, 739 (90.1%) were considered to be diagnostically useful, and 327 (39.9%) changed management. Conclusions These findings suggest LUS was diagnostically useful and routinely changed management in hospitalist practice. Further, documentation in the EHR was sufficient to allow for the evaluation of real-world clinical decision-making using LUS, which is an important gap in both the education and health services research literature.

Information exchange, responsibilities and expectation management in interhospital transfers: a qualitative study of hospital medicine physicians and advanced practice providers.

INTRODUCTION: The transfer of patients between hospitals, known as interhospital transfer (IHT), is associated with higher rates of mortality, longer lengths of stay and greater resource utilisation compared with admissions from the emergency department. To characterise the IHT process and identify key barriers and facilitators to IHT care, we examined the experiences of physician and advanced practice provider (APP) hospital medicine clinicians who care for IHT patients transferred to their facility. METHODS: Qualitative descriptive study using semistructured interviews with adult medicine hospitalists from an academic acute care hospital that accepts approximately 4000 IHT patients annually. A combined inductive and deductive coding approach guided thematic analysis. RESULTS: We interviewed 30 hospitalists with a mean of 5.7 years of experience. Two-thirds of interviewees were physicians and one-third were APPs.They described IHTs as challenging when (1) exchanged information was incomplete, inaccurate, extraneous, and/or untimely, (2) uncertainty impacted care responsibilities and (3) healthcare team members and patients had differing care expectations. As a result, participants described patient safety issues such as delays in care and inappropriate triage of patients due to incomplete communication of clinical status changes.Recommended improvement strategies include (1) dedicated individuals performing IHT tasks to improve consistency of information exchanged and relationships with transferring clinicians, (2) standardised scripts and documentation, (3) bidirectional communication, (4) interdisciplinary training and (5) shared understanding of care needs and expectations. CONCLUSIONS: Physicians and APP hospital medicine clinicians at an accepting hospital found information exchange, care responsibilities and expectation management challenging in IHT. In turn, hospitalists perceived a negative impact on IHT patient care and safety. Highly reliable and timely information transfer, standardisation of IHT processes and clear interdisciplinary communication may facilitate improved care for IHT patients.

A Qualitative Study of Internal Medicine Subspecialty Fellowship Program Directors' Perspectives on Short-Term Hospitalist Employment Prior to Fellowship.

Background Some internal medicine (IM) residents pursuing subspecialty training choose short-term hospitalist employment prior to fellowship, or "pre-fellowship hospitalist years." Residency and fellowship program directors (PDs) advise residents on this decision, but PD experience with fellows pursuing pre-fellowship hospitalist years and the impact on fellowship applications is unknown. Objective We aimed to explore perceptions of fellowship PDs regarding experience with fellows who pursued pre-fellowship hospitalist years, including perceived effects on how such years affect fellowship application candidacy. Methods A purposive sample of 20 fellowship PDs in the most highly competitive and commonly selected IM fellowships (cardiology, pulmonology/critical care medicine, hematology/oncology, gastroenterology) from 5 academic institutions were approached for participation in fall 2021. Interviews included semi-structured questions about pre-fellowship hospitalist employment. Utilizing rapid qualitative analysis, interview transcripts were summarized and reviewed to identify themes and subthemes describing fellowship PDs' perspectives of pre-fellowship hospitalist years. Results Sixteen fellowship PDs (80%) participated. PDs identified 4 major themes as important for trainees considering pre-fellowship hospitalist years: (1) Explain the "Why"-why the year was pursued; (2) Characteristics of the Hospitalist Position-what type of employment; (3) The Challenges-potential concerns faced with pre-fellowship hospitalist years; and (4) Describe the "What"-the experience's contribution to resident professional development. Conclusions Fellowship PDs in 4 competitive IM subspecialities placed a strong emphasis on explaining a clear, logical reason for seeking short-term hospitalist employment prior to fellowship, describing how it fits into the overall career trajectory, and selecting activities that demonstrate continued commitment to the subspecialty.

The development and pilot of a novel mobile application to assess clinician perception of workload and work environment.

BACKGROUND: Traditional measures of workload such as wRVUs may not be adequate to understand the impact of workload on key outcomes. OBJECTIVE: The objective of this study was to develop a mobile application to assess, in near real time, clinicians' perception of workload and work environment. DESIGNS, SETTINGS AND PARTICIPANTS: We developed the GrittyWork™ application (GW App) using the Chokshi and Mann process model for user-centered digital development. Study occured at a single academic medical center with hospitalist clinicians. MAIN OUTCOME MEASURES AND MEASURES: Measures included the System Usability Scale (SUS), use measures from GW App, electronic health record (EHR) event log data and note counts, and qualitative interviews. RESULTS: From October 28, 2022 to November 3, 2022, six hospitalist clinicians provided feedback on the early prototype of the GW App, and from February 28, 2023 to June 8, 2023, 30 hospitalist clinicians participated in the pilot while on clinical service. All 30 clinicians (100%) participated in the pilot submitting data for a total of 122 shifts. Participants reported working 10 ± 1 h per day (mean ± SD) and were responsible for an average of 11 ± 3 patients per day. The postpilot evaluation of the GW App showed a SUS score of 86 ± 11 and a participant preference toward mobile application-based surveys (73% of participants). Regarding workload measures, EHR event log data and notes data correlated with physician-reported workloads. Applying user-centered design techniques, we successfully developed a mobile application with high usability. These data can be paired with EHR event log data and outcomes to provide insights into the impact of workloads and work environments on outcomes.

Peer feedback: A tool to improve PA, NP, and physician collaboration and clinical practice.

ABSTRACT: The increasing use of physician associates/assistants (PAs) and NPs on clinical teams creates an opportunity for colleagues to provide feedback that can drive growth and improvement in PA and NP clinical skills. Through a needs assessment, month-long pilot, and buy-in from our academic hospital medicine group, we initiated a peer feedback platform that sought to highlight individual faculty strengths, facilitate thoughtful and constructive feedback, and create effective collaboration among colleagues. Three months after implementation, results indicated that the platform provided important information on clinical skills and identified areas for growth and opportunities for additional training. Peer feedback can also improve working relationships among PAs, NPs, and physicians by highlighting the clinical skill sets and value of all team members.

A patient follow-up intervention to improve medical decision making at an internal medicine residency program.

OBJECTIVES: Practice-based learning and improvement (PBLI) is an ACGME (Accreditation Council for Graduate Medical Education) core competency. Learning and reflecting on patients through follow-up is one method to help achieve this competency. We therefore designed a study evaluating a structured patient follow-up intervention for senior internal medicine (IM) residents at the University of Colorado Hospital (UCH). METHODS: Trainees completed structured reflections after performing chart review of prior patients during protected educational time. Two-month follow-up surveys evaluated the exercise's potential influence on clinical and reflective practices. RESULTS: Forty out of 108 (37 %) eligible residents participated in the exercise. Despite 62.5 % of participants lacking specific questions about patient outcomes before chart review, 81.2 % found the exercise at least moderately helpful. 48.4 % of participants believed that the review would change their practice, and 60.9 % felt it reinforced their existing clinical practices. In our qualitative data, residents learned lessons related to challenging clinical decisions, improving transitions of care, the significance of early goals of care conversations, and diagnostic errors/strategies. CONCLUSIONS: Our results indicate that IM residents found a structured patient follow-up intervention educational, even when they lacked specific patient outcomes questions. Our results underscore the importance of structured self-reflection in the continuous learning process of trainees and suggest the benefit of dedicated educational time for this process.

Evaluation of a Guided Nature and Forest Therapy Walk for Internal Medical Residents - A Brief Report.

Background: Medical residents commonly face compassion fatigue, burnout, anxiety, and depression. Studies of nature-based interventions show improved mental and physical health; few focus on healthcare providers. Objective: To explore potential benefits of forest bathing for medical residents' wellbeing. Methods: Using the Association of Nature and Forest Therapy's framework, we piloted a forest bathing intervention among medical residents with pre/post-participation surveys assessing perceptions of mindfulness and psychological wellbeing. Responses were analyzed using a Fisher's exact test and Student's t-test for independent samples. Results: Fourteen of fifteen participants completed both surveys. We observed significantly improved mindfulness scores and expressions of feeling calm, vital, or creative, as well as a decreased sense of anxiety and depression. Nonsignificant trends towards decreased burnout and irritability were seen. Conclusion: This quality improvement pilot demonstrates trends that forest bathing can improve medical residents' psychological wellbeing and mindfulness. Further exploration of this intervention for healthcare providers is warranted.

The Impact of Completing X-Waiver Training and Clinical Addiction Exposure on Internal Medicine Residents Treating Patients With Opioid Use Disorder.

BACKGROUND: Treating opioid use disorder (OUD) with buprenorphine or methadone significantly reduces overdose and all-cause mortality. Prior studies demonstrate that clinicians and residents reported a lack of preparedness to diagnose or treat OUD. Little is known about how clinical exposure or buprenorphine X-waiver training impacts OUD care delivery by resident physicians. OBJECTIVE: Distinguish the effects of X-waiver training and clinical exposure with OUD on resident's knowledge, attitudes, feelings of preparedness, and practices related to OUD treatment provision. METHODS: From August 2021 to April 2022, we distributed a cross-sectional survey to internal medicine residents at a large academic training program. We analyzed associations between self-reported clinical exposure and X-waiver training across 4 domains: knowledge about best practices for OUD treatment, attitudes about patients with OUD, preparedness to treat OUD, and clinical experience with OUD. RESULTS: Of the 188 residents surveyed, 91 responded (48%). A majority of respondents had not completed X-waiver training (60%, n = 55) while many had provided clinical care to patients with OUD (65%, n = 59). Most residents had favorable attitudes about OUD treatment (97%). Both residents with clinical exposure to treating OUD and X-waiver training, and residents with clinical exposure without X-waiver training, felt more prepared to treat OUD (P < .0008) compared to residents with neither clinical exposure or X-waiver training or only X-waiver training. CONCLUSIONS: Residents with clinical exposure to treating OUD are more prepared to treat patients with OUD than those without clinical exposure. Greater efforts to incorporate clinical exposure to the treatment of OUD and education in internal medicine residency programs is imperative to address the opioid epidemic.

Prevalence of homelessness among hospitalized patients: A point-in-time survey.

Although homelessness is associated with increased acute healthcare utilization and poorer health outcomes, the prevalence of homelessness and housing insecurity in hospitalized patients is poorly characterized. We conducted an in-person survey to determine the prevalence of housing insecurity and homelessness among hospitalized patients at two hospitals in metropolitan Denver in conjunction with the Housing and Urban Development point-in-time count on January 24, 2022. Of the 271 surveyed patients, 79 (29.2%) reported experiencing either housing insecurity (17.3%) or homelessness (11.8%). Of those experiencing housing insecurity or homelessness, 69.6% reported chronic health conditions, 55.7% reported multiple hospitalizations in the preceding year, 38% reported mental health concerns and 39.2% reported substance use. The prevalence of homelessness among a hospitalized patient population was over 20-fold higher than community prevalence estimates. Housing insecurity also impacted a substantial proportion of hospitalized patients and was associated with high rates of co-morbid conditions.

Impact of Clinical Demands on the Educational Mission in Hospital Medicine at 17 Academic Medical Centers : A Qualitative Analysis.

BACKGROUND: Clinical growth is outpacing the growth of traditional educational opportunities at academic medical centers (AMCs). OBJECTIVE: To understand the impact of clinical growth on the educational mission for academic hospitalists. DESIGN: Qualitative study using semistructured interviews that were analyzed using a mixed inductive and deductive method at the semantic level. SETTING: Large AMCs across the United States that experienced clinical growth in the past 5 years. PARTICIPANTS: Division heads, section heads, and other hospital medicine (HM) leaders who oversaw and guided academic and clinical efforts of HM programs. MEASUREMENTS: Themes and subthemes. RESULTS: From September 2021 to January 2022, HM leaders from 17 AMCs participated in the interviews, and 3 key themes emerged. First, AMCs' disproportionate clinical growth highlighted the tension between clinical and educational missions. This included a mismatch in supply and demand for traditional teaching time, competing priorities, and clinical growth being seen as both an opportunity and a threat. Second, amid the shifting landscape of high clinical demands and evolving educational opportunities, hospitalists still strongly prefer traditional teaching. To address this mismatch, HM groups have had to alter recruitment strategies and create innovative solutions to help build academic careers. Third, participants noted a need to reimagine the role and identity of an academic hospitalist, emphasizing tailored career pathways and educational roles spanning well beyond traditional house staff teaching teams. LIMITATION: The study focused on large AMCs. CONCLUSION: Although HM groups have implemented many creative strategies to address clinical growth and keep education front and center, challenges remain, particularly heavy clinical workloads and a continued dilution of traditional teaching opportunities.

Hospitalization and Housing: A Qualitative Study Exploring the Perspectives of Hospitalized Patients Experiencing Housing Insecurity.

Although housing insecurity has clear negative impacts on health, little is known about how it impacts patients' experience of hospitalization. In this qualitative study, we interviewed 22 hospitalized patients experiencing housing insecurity. The following three major themes emerged: 1) adverse social and environmental factors directly contribute to hospitalization, 2) lack of tailored care during hospitalization leaves patients unprepared for discharge, and 3) patients have difficulty recuperating after a hospital stay, leading to the risk of rehospitalization. Within these themes, participants described the roles of extreme physical and psychological hardship, chaotic interpersonal relationships, substance use, and stigma affecting participants' experiences before, during, and following hospitalization. Our results, based directly on the patient experience, suggest a need for hospital systems to invest in universal in-hospital screening for housing insecurity, incorporation of trauma-informed care, and robust partnerships with community organizations. Future research should explore the feasibility and impact of these interventions.

Salient Measures of Hospitalist Workload.

Importance: The ideal hospitalist workload and optimal way to measure it are not well understood. Objective: To obtain expert consensus on the salient measures of hospitalist workload. Design, Setting, and Participants: This qualitative study used a 3-round Delphi technique between April 5 and July 13, 2022, involving national experts within and external to the field. Experts included hospitalist clinicians, leaders, and administrators, as well as researchers with expertise in human factors engineering and cognitive load theory. Main Outcomes and Measures: Three rounds of surveys were conducted, during which participants provided input on the salient measures of hospitalist workload across various domains. In the first round, free-text data collected from the surveys were analyzed using a directed qualitative content approach. In the second and third rounds, participants rated each measure's relevance on a Likert scale, and consensus was evaluated using the IQR. Percentage agreement was also calculated. Results: Seventeen individuals from 14 organizations, encompassing clinicians, leaders, administrators, and researchers, participated in 3 rounds of surveys. In round 1, participants provided 135 unique qualitative comments across 10 domains, with 192 unique measures identified. Of the 192 measures presented in the second round, 6 (3%) were considered highly relevant, and 25 (13%) were considered moderately relevant. In round 3, 161 measures not meeting consensus were evaluated, with 25 (16%) considered highly relevant and 95 (59%) considered moderately relevant. Examples of measures considered highly relevant included a patient complexity score and outcome measures such as savings from hospital days avoided and clinician turnover. Conclusions and Relevance: In this qualitative study measuring hospitalist workload, multiple measures, including those quantifying work demands and the association of those demands with outcomes, were considered relevant for measuring and understanding workloads. The findings suggest that relying on traditional measures, such as productivity-related measures and financial measures, may offer an incomplete understanding of workloads and their association with key outcomes. By embracing a broader range of measures, organizations may be able to better capture the complexity and nuances of hospitalist work demands and their outcomes on clinicians, patients, and organizations.

Discharge in the a.m.: A randomized controlled trial of physician rounding styles to improve hospital throughput and length of stay.

BACKGROUND: To relieve hospital capacity strain, hospitals often encourage clinicians to prioritize early morning discharges which may have unintended consequences. OBJECTIVE: We aimed to test the effects of hospitalist physicians prioritizing discharging patients first compared to usual rounding style. DESIGN, SETTING AND PARTICIPANTS: Prospective, multi-center randomized controlled trial. Three large academic hospitals. Participants were Hospital Medicine attending-level physicians and patients the physicians cared for during the study who were at least 18 years of age, admitted to a Medicine service, and assigned by standard practice to a hospitalist team. INTERVENTION: Physicians were randomized to: (1) prioritizing discharging patients first as care allowed or (2) usual practice. MAIN OUTCOME AND MEASURES: Main outcome measure was discharge order time. Secondary outcomes were actual discharge time, length of stay (LOS), and order times for procedures, consults, and imaging. RESULTS: From February 9, 2021, to July 31, 2021, 4437 patients were discharged by 59 physicians randomized to prioritize discharging patients first or round per usual practice. In primary adjusted analyses (intention-to-treat), findings showed no significant difference for discharge order time (13:03 ± 2 h:31 min vs. 13:11 ± 2 h:33 min, p = .11) or discharge time (15:22 ± 2 h:50 min vs. 15:21 ± 2 h:50 min, p = .45), for physicians randomized to prioritize discharging patients first compared to physicians using usual rounding style, respectively, and there was no significant change in LOS or on order times of other physician orders. CONCLUSIONS: Prioritizing discharging patients first did not result in significantly earlier discharges or reduced LOS.

Practical Applications of Rapid Qualitative Analysis for Operations, Quality Improvement, and Research in Dynamically Changing Hospital Environments.

BACKGROUND: Health care systems are in a constant state of change. As such, methods to quickly acquire and analyze data are essential to effectively evaluate current processes and improvement projects. Rapid qualitative analysis offers an expeditious approach to evaluate complex, dynamic, and time-sensitive issues. METHODS: We used rapid data acquisition and qualitative methods to assess six real-world problems the hospitalist field faced during the COVID-19 pandemic. We iteratively modified and applied a six-step framework for conducting rapid qualitative analysis, including determining if rapid methods are appropriate, creating a team, selecting a data collection approach, data analysis, and synthesis and dissemination. Virtual platforms were used for focus groups and interviews; templated summaries and matrix analyses were then applied to allow for rapid qualitative analyses. RESULTS: We conducted six projects using rapid data acquisition and rapid qualitative analysis from December 4, 2020, to January 14, 2022, each of which included 23 to 33 participants. One project involved participants from a single institution; the remainder included participants from 15 to 24 institutions. These projects led to the refinement of an adapted rapid qualitative method for evaluation of hospitalist-driven operational, research, and quality improvement efforts. We describe how we used these methods and disseminated our results. We also discuss situations for which rapid qualitative methods are well-suited and strengths and weaknesses of the methods. CONCLUSION: Rapid qualitative methods paired with rapid data acquisition can be employed for prompt turnaround assessments of quality, operational, and research projects in complex health care environments. Although rapid qualitative analysis is not meant to replace more traditional qualitative methods, it may be appropriate in certain situations. Application of a framework to guide projects using a rapid qualitative approach can help provide structure to the analysis and instill confidence in the findings.

Inpatient clinician workload: a scoping review protocol to understand the definition, measurement and impact of non-procedural clinician workloads.

INTRODUCTION: Clinicians that care for hospitalised patients face unprecedented work conditions with exposure to highly infectious disease, exceedingly high patient numbers, and unpredictable work demands, all of which have resulted in increases in stress and burnout. Preliminary studies suggest that increasing workloads negatively affect inpatient clinician well-being and may negatively affect job performance; yet high workloads may be prioritised secondary to financial drivers or from workforce shortages. Despite this, the correlation between workload and these negative outcomes has not been fully quantified. Additionally, there are no clear measures for inpatient clinician workload and no standards to define ideal workloads. Using the protocol described here, we will perform a scoping review of the literature to generate a comprehensive understanding of how clinician workload of medical patients is currently defined, measured in clinical settings and its impact on the workforce, patients and institutional outcomes. METHODS AND ANALYSIS: We will follow the methodology outlined by Joanna Briggs Institute and Arksey and O'Malley to conduct a comprehensive search of major electronic databases including Ovid Medline (PubMed), Embase (Embase.com), PsycINFO, ProQuest Dissertations and Google Scholar. All relevant published peer-reviewed and dissertaion grey literature will be included. Data will be extracted using a standardised form to capture key article information. Results will be presented in a descriptive narrative format. ETHICS AND DISSEMINATION: This review does not require ethics approval though all included studies will be screened to ensure appropriate approval. The synthesis of this literature will provide a better understanding of the current state of work for inpatient clinicians, associated outcomes, and will identify gaps in the literature. These findings will be used in conjunction with an expert Delphi panel to identify measures of inpatient clinician workload to then guide the development of a novel workforce mobile application to actively track clinician work. We aim to lay the groundwork for future workforce studies to understand the optimal workloads that drive key outcomes for clinicians, patients and institutions.

Utilization of a National Writing Challenge to Promote Scholarly Work: A Pilot Study.

Background Hospitalists value mentorship and scholarly work, yet often struggle to find time and mentors amid busy clinical workloads. Objective To help catalyze writing for hospitalists nationally, we created a Writing Challenge, where we asked hospitalists to commit to the goal of writing 400 words a day, four days a week, for four weeks. Methods Prospective, programmatic evaluation with daily logs followed by a survey at the completion of the project. The four-week Writing Challenge occurred between June 7 and July 5, 2021. Email invitations to participate in the challenge were disseminated to peer networks, and the challenge was promoted using social media. Participants agreed to attempt to write 400 words per day, four days per week, for four weeks. Results Seventy-four individuals from 28 institutions registered for the Writing Challenge, with 36 (49%) participating in the challenge by logging their writing. Participants wrote an average of 4,372 +/- 4,324 words during the challenge. Sixty-eight percent of the participants reported that their amount of writing increased during the challenge and 50% of the participants stated they planned to publish their work, though many participants (46%) reported struggling to write each day. Conclusions The Writing Challenge is one way to generate increased writing and may result in increased scholarly output for academic hospitalists.

The impact of surge adaptations on hospitalist care teams during the COVID-19 pandemic utilizing a rapid qualitative analysis approach.

BACKGROUND: Hospital systems have rapidly adapted to manage the influx of patients with COVID-19 and hospitalists, specialists in inpatient care, have been at the forefront of this response, rapidly adapting to serve the ever-changing needs of the community and hospital system. Institutional leaders, including clinical care team members and administrators, deployed many different strategies (i.e. adaptations) to manage the influx of patients. While many different strategies were utilized in hospitals across the United States, it is unclear how frontline care teams experienced these strategies and multifaceted changes. As these surge adaptations likely directly impact clinical care teams, we aimed to understand the perceptions and impact of these clinical care and staffing adaptations on hospitalists and care team members in order to optimize future surge plans. METHODS: Qualitative, semi-structured interviews and focus groups with hospitalist physicians, advanced practice providers (APPs), and hospital nursing and care management staff at a quaternary academic medical center. Interviews focused on the impact of COVID-19 surge practices on the following areas: (1) the experience of clinical care teams with the adaptations used to manage the surge (2) the perception and experience with the communication strategies utilized (3) the personal experience with the adaptations (i.e. how they impacted the individual) and (4) if participants had recommendations on strategies for future surges. We utilized rapid qualitative analysis methods to explore themes and subthemes. RESULTS: We conducted five focus groups and 21 interviews. Three themes emerged from the work including (1) dynamic clinical experience with a lot of uncertainty, (2) the importance of visible leadership with a focus on sense-making, and (3) the significant emotional toll on care team members. Subthemes included sufficient workforce, role delineation and training, information sharing, the unique dichotomy between the need for flexibility and the need for structure, the importance of communication, and the emotional toll not only on the provider but their families. Several recommendations came from this work. CONCLUSIONS: COVID-19 surge practices have had direct impact on hospitalists and care team members. Several tactics were identified to help mitigate the many negative effects of COVID-19 on frontline hospitalist providers and care teams.
