Bacterial coinfections in COVID-19-hospitalized patients

OBJECTIVE

The aim of this study was to assess the rate of bacterial infections in COVID-19-hospitalized patients and to analyze the most prevalent germs, sources, risk factors, and its impact on in-hospital mortality.

METHODS

This observational retrospective study was conducted on 672 patients hospitalized between April and August 2020 in Nossa Senhora da Conceição Hospital, a public hospital located in Porto Alegre, Brazil. The inclusion criterion was adult patients hospitalized with confirmed COVID-19. Data were collected through chart review. Risk factors for bacterial infection and mortality were analyzed using both univariate and multivariate robust Poisson regression models.

RESULTS

Bacterial coinfection was observed in 22.2% of patients. Risk factors for bacterial infections were dementia (RR=2.06 (1.18-3.60); p=0.011), cerebrovascular disease (RR=1.75 (1.15-2.67); p=0.009), active cancer (RR=1.52 (1.082-2.15); p=0.01), need for noninvasive ventilation (RR=2.320 (1.740-3.094); p<0.01), invasive mechanical ventilation (RR=4.63 (2.24-9.56); p<0.01), and renal replacement therapy (RR=1.68 (1.26-2.25); p<0.01). In the adjusted model, bacterial infections were not associated with mortality (0.96 (0.75-1.24); p=0.79). The most common source of infection was due to respiratory, blood, and central venous catheters, with 69 (29.36%), 61 (25.96%), and 59 (25.11%) positive cultures, respectively.

CONCLUSION

We observed a high rate of bacterial infections in COVID-19-hospitalized patients, most commonly of respiratory source. Neurologic and oncologic morbidities and need for ventilation and renal replacement therapy was associated with risk factors for bacterial infections. Nevertheless, an association between bacterial infections and hospital mortality was not established.

Association of pharmacologic thromboprophylaxis with clinically relevant bleeding and hospital-acquired anemia in medical inpatients: the risk stratification for hospital-acquired venous thromboembolism in medical patients study

BACKGROUND

Pharmacologic thromboprophylaxis (pTPX) might exacerbate the risk of clinically relevant bleeding (CRB) and hospital-acquired anemia (HAA) in older multimorbid inpatients.

OBJECTIVES

We aimed to evaluate the association of pTPX use with CRB and HAA.

METHODS

We used data from a prospective cohort study conducted in 3 Swiss university hospitals. Adult patients admitted to internal medicine wards with no therapeutic anticoagulation were included. pTPX use was ascertained during hospitalization. Outcomes were in-hospital CRB and HAA. We calculated incidence rates by status of pTPX. We assessed the association of pTPX with CRB using survival analysis and with HAA using logistic regression, adjusted for infection, length of stay, and the International Medical Prevention Registry on Venous Thromboembolism bleeding risk score.

RESULTS

Among 1305 patients (mean age, 63.7 years; 44% women, 90% at low risk of bleeding), 809 (62%) received pTPX. The incidence of CRB was 2.4 per 1000 patient-days and was not significantly higher in patients with pTPX than in those without. We found no significant association between pTPX and CRB. HAA was frequent (20.2%) and higher in patients with pTPX than in those without (23.2% vs 15.3%). The incidence of HAA was 21.2 per 1000 patient-days and did not significantly differ between patients with pTPX and those without. We found an association between pTPX and HAA (adjusted odds ratio, 1.4; 95% CI, 1.0-2.1).

CONCLUSION

Our study confirmed the safety of pTPX in medical inpatients at low risk of bleeding but identified an association between pTPX and HAA. Adherence to guidelines that recommend administering pTPX to medical inpatients at increased venous thromboembolism risk and low bleeding risk is necessary.

Defining Incidental Versus Non-incidental COVID-19 Hospitalizations

Background Rates of COVID-19 hospitalization are an important measure of the health system burden of severe COVID-19 disease and have been closely followed throughout the pandemic. The highly transmittable, but often less severe, Omicron COVID-19 variant has led to an increase in hospitalizations with incidental COVID-19 diagnoses where COVID-19 is not the primary reason for admission. There is a strong public health need for a measure that is implementable at low cost with standard electronic health record (EHR) datasets that can separate these incidental hospitalizations from non-incidental hospitalizations where COVID-19 is the primary cause or an important contributor. Two crude metrics are in common use. The first uses in-hospital administration of dexamethasone as a marker of non-incidental COVID-19 hospitalizations. The second, used by the United States (US) CDC, relies on a limited set of COVID-19-related diagnoses (i.e., respiratory failure, pneumonia). Both measures likely undercount non-incidental COVID-19 hospitalizations. We therefore developed an improved EHR-based measure that is better able to capture the full range of COVID-19 hospitalizations. Methods We conducted a retrospective study of ED visit data from a national emergency medicine group from April 2020 to August 2023. We assessed the CDC approach, the dexamethasone-based measure, and alternative approaches that rely on co-diagnoses likely to be related to COVID-19, to determine the proportion of non-incidental COVID-19 hospitalizations. Results Of the 153,325 patients diagnosed with COVID-19 at 112 general EDs in 17 US states, and admitted or transferred, our preferred measure classified 108,243 (70.6%) as non-incidental, compared to 71,066 (46.3%) using the dexamethasone measure and 77,399 (50.5%) using the CDC measure. Conclusions Identifying non-incidental COVID-19 hospitalizations using ED administration of dexamethasone or the CDC measure provides substantially lower estimates than our preferred measure.

Decoding Altered Consciousness: An Artery of Percheron Stroke

The artery of Percheron (AOP) is a unique variant of the thalamic and midbrain perforating arteries. It originates from the P1 branch of the posterior cerebral artery (PCA) and supplies the bilateral paramedian thalami (BPT) along with variable contributions to the rostral midbrain. Four infarction patterns have been identified as a result of an AOP stroke, each associated with varying prognostic outcomes. We present an 89-year-old female with an AOP infarction and discuss the associated symptoms, implicated anatomy, and prognosis.

Evaluating the impact of interprofessional training wards on patient satisfaction and clinical outcomes: a mixed-methods analysis

Introduction

Interprofessional teamwork is pivotal in modern healthcare, prompting the establishment of interprofessional training wards since 1996. While these wards serve as hubs for optimizing healthcare professional collaboration and communication, research into patient outcomes remains notably sparse and geographically limited, predominantly examining patient satisfaction and sparingly exploring other metrics like mortality or self-discharge rates. This study seeks to bridge this gap, comparing patient outcomes in interprofessional training wards and conventional wards under the hypothesis that the former offers no disadvantage to patient outcomes.

Materials and methods

We explored patient outcomes within an interprofessional student ward called A-STAR at a University Hospital from October 2019 to December 2022. Engaging with patients discharged between May 2021 and April 2022, we utilized digital and paper-based anonymous questionnaires, catering to patient preference, to gather pertinent data.

Results

Analysis of outcomes for 1,482 A-STAR (interprofessional student ward) and 5,752 conventional ward patients revealed noteworthy findings. A-STAR patients tended to be younger (59 vs. 61 years, p < 0.01) and more frequently male (73.5% vs. 70.4%, p = 0.025). Vital clinical outcomes, such as discharges against medical advice, complication-driven readmissions, and ICU transfers, were statistically similar between groups, as were mortality rates (1.2% vs. 1.3%, p = 0.468). A-STAR demonstrated high patient satisfaction, underscored by positive reflections on team competence, ward atmosphere, and responsiveness to concerns, emphasizing the value placed on interprofessional collaboration. Patient narratives commended team kindness, lucid explanations, and proactive involvement.

Discussion

This data collectively underscores the safety and reliability of patient care within training wards, affirming that patients can trust the care provided in these settings. Patients on the interprofessional ward demonstrated high satisfaction levels: 96.7% appreciated the atmosphere and conduct of ward rounds. In comparison, 98.3% were satisfied with the discussion and information about their treatment during their hospital stay.

Serum proteome profiling reveals heparanase as a candidate biomarker for chronic thromboembolic pulmonary hypertension

Determining novel biomarkers for early identification of chronic thromboembolic pulmonary hypertension (CTEPH) could improve patient outcomes. We used the isobaric tag for relative and absolute quantitation approach to compare the serum protein profiles between CTEPH patients and the controls. Bioinformatics analyses and ELISA were also performed. We identified three proteins including heparanase (HPSE), gelsolin (GSN), and secreted protein acidic and rich in cysteine (SPARC) had significant changes in CTEPH. The receiver operating characteristic curve analysis showed that the areas under the curve of HPSE in CTEPH diagnosis were 0.988. Furthermore, HPSE was correlated with multiple parameters of right ventricular function. HPSE concentrations were significantly higher in patients with a low TAPSE/sPAP ratio (≤0.31 mm/mmHg) (65.4 [60.5,68.0] vs. 59.9 [35.9,63.2] ng/mL, p < 0.05). The CTEPH patients treated by balloon pulmonary angioplasty had significantly lower HPSE levels. The study demonstrates that HPSE may be a promising biomarker for noninvasive detection of CTEPH.

Short-term parenteral infusions with high-osmolality amino acid solutions can be safely administered through peripheral catheters in dogs treated for hypoaminoacidemia-related conditions

OBJECTIVE

To compare complications between central and peripheral administration of high-osmolarity (approx 700 to 1,000 mOsm/L) amino acid (± lipid) infusions.

ANIMALS

18 client-owned dogs diagnosed with aminoaciduric canine hypoaminoacidemic hepatopathy syndrome or superficial necrolytic dermatitis receiving parenteral amino acid ± lipid infusions.

METHODS

In this retrospective case series, medical records were reviewed for administration route (central vs peripheral), catheter details and infusion characteristics (product osmolarity, concurrent lipid administration, infusion volume, duration, and rate), and complications for each infusion.

RESULTS

18 dogs received 277 infusions (median, 8.5; range, 1 to 84). Effective infusion osmolarities were 683 mOsm/L in 22% of infusions, 791 mOsm/L in 8%, 802 mOsm/L in 2%, 837 mOsm/L in 45%, and 998 mOsm/L in 23% (65% peripheral, 35% central). Most (n = 230 [83%]) infusions were given peripherally. The osmolarities of solutions administered by each route (P = .53), the infusion rate indexed to body weight (P = .17), or the lipid infusion rates indexed to body weight (P = .89) did not differ. One dog suffered 2 complications in 63 infusions-1 mild, 1 severe-both occurring with peripheral infusions. Thus, the overall complication rate was 2 of 277 (0.9%) infusions.

CLINICAL RELEVANCE

Short-term peripherally administered amino acid ± lipid infusions < 1,000 mOsm/L confer little risk compared to centrally administered infusions. Additional studies are needed to determine the safety of infusions with longer durations. Due to the relative ease of peripheral catheterization, clinicians should consider this route for medically managing aminoaciduric canine hypoaminoacidemic hepatopathy syndrome and superficial necrolytic dermatitis in dogs.

Increasing the Rate of Venous Thromboembolism Chemoprophylaxis Administration Using the Electronic Medical Record

Introduction: Venous thromboembolism (VTE) remains a leading cause of preventable harm among hospitalized patients. Pharmacologic VTE prophylaxis reduces the rate of in-hospital VTE by 60%, but medication administration is often missed for various reasons. Electronic medical record (EMR) prompts may be a useful tool to decrease withholding of critical VTE chemoprophylaxis medications. Methods: In August 2021, an EMR prompt was implemented at a tertiary referral academic medical center mandating nursing staff to contact a provider for approval before withholding VTE chemoprophylaxis. A pre-intervention group from August 2020 to August 2021 was compared to a post-intervention group from August 2021 to August 2022. Rates of VTE chemoprophylaxis withholding were compared between the groups with a P < .01 considered significant. Results: A total of 16,395 patients prescribed VTE chemoprophylaxis were reviewed, with 13,395 (81.7%) receiving low molecular weight heparin. Of the 16,395 patients included, 10,701 (65.3%) were medical and 5694 (34.7%) were surgical. Patients in the pre-intervention cohort (n = 8803) and post-intervention cohort (n = 7592) were similar in hospital length of stay and duration of DVT prophylaxis. In the post-intervention group, the frequency of surgical patients with at least one missed dose had increased by 4.2% (P = .002), with the trauma and acute care surgery (TACS) show an increase of 6.6% (P < .001). However, the frequency of medical patients and non-TACS patients with missed doses decreased by 3.1% (P = .002) and 1.0% (<.001), respectively. Conclusions: EMR prompts appear to be a low-cost intervention that increases the rate of VTE prophylaxis administration among medical and elective surgery patients.

How do sepsis survivors experience life after sepsis? A Danish qualitative study exploring factors of importance

OBJECTIVE

Sepsis is a condition associated with high mortality and morbidity, and survivors often experience physical and psychological decline. Previous research has primarily focused on sepsis survivors discharged from the intensive care unit (ICU). We aimed to explore and understand the consequences of sepsis experienced by sepsis survivors in general.

DESIGN

A qualitative study inspired by a phenomenological hermeneutical approach was conducted. Data were analysed using systematic text condensation.

SETTING

Patients with sepsis were identified on admission to the emergency department and invited to an interview 3 months after discharge.

PARTICIPANTS

Sixteen sepsis survivors were purposively sampled and interviewed. Among these survivors, one patient was admitted to the ICU.

RESULTS

Three main themes were derived from the analysis: new roles in life, cognitive impairment and anxiety. Although many survivors described a physical decline, they experienced psychological and cognitive impairments after sepsis as the most influential factors in daily life. The survivors frequently experienced fatigue, withdrawals from social activities and anxiety.

CONCLUSION

Sepsis survivors' experiences appeared to overlap regardless of ICU admission or treatment at the general ward. Identifying patients with sepsis-related decline is important to understand and support overall patient processes and necessary in meeting specific needs of these patients after hospital discharge.

Evaluation of Lead-In Direct Oral Anticoagulant Prescribing Practices in Newly Diagnosed Venous Thromboembolism

Various lead-in dosing strategies have been used in clinical practice for venous thromboembolism (VTE), and guidelines do not currently address if the full lead-in dosing duration is necessary after receiving parenteral anticoagulation. This study aims to identify whether full lead-in dosing duration surrounding parenteral anticoagulation affects thrombotic and bleeding outcomes. A single-center, retrospective cohort study was conducted of hospitalized patients diagnosed with VTE and treated with apixaban or rivaroxaban. Patients were grouped depending on duration of lead-in dosing, with the full lead-in dosing group considered as the appropriate duration of the direct oral anticoagulant. The primary outcome was the recurrence of VTE within the index admission to 6 months. Secondary outcomes included major bleeding, clinically relevant minor bleeding, and mortality. Ninety-three patients were prescribed full lead-in dosing, while 99 patients received reduced lead-in dosing. The primary outcome of recurrent VTE was similar between the reduced lead-in group compared to the full lead-in group (3% vs 2%; P = 1.0). Major bleeding within the index admission was significantly higher in the reduced lead-in group: 11 versus 2 (P = .02). There were no significant differences in other secondary outcomes. Full lead-in dosing compared to reduced lead-in dosing duration for VTE had similar rates of thrombotic and mortality events. The higher rate of major bleeding in the reduced lead-in dosing group likely reflects the prescribing practices in less stable patients. This study provides evidence to support reduced lead-in dosing duration in high-risk patients without compromising efficacy outcomes.

Implementation and Evaluation of a Pilot Narrative Medicine Curriculum for Internal Medicine Residents

Background Narrative medicine has been integrated into medical training to enhance competencies such as observation, reflection, and self-care. However, few studies have assessed the impact of a single narrative medicine session using a pre- and post-test study design. The authors of this study sought to implement a pilot narrative medicine curriculum into a large internal medicine residency program and to evaluate its feasibility and impact. Methodology The curriculum consisted of a one-hour reading and writing workshop held during ambulatory academic half-days from 2021 to 2022. Resident participants completed a retrospective pre- and post-workshop survey evaluating their interest and confidence in practicing narrative medicine skills, as well as their beliefs about the impacts of narrative medicine on patient care and provider well-being. Descriptive statistics evaluated pre- and post-workshop differences using the Wilcoxon signed-rank test. Subgroup analyses were conducted based on postgraduate year, residency track, and workshop setting. Additionally, participants completed open-ended questions that were analyzed qualitatively. Results Of 218 resident participants, 152 (69.7%) completed the post-session survey. Participants noted significantly higher levels of confidence and interest in listening to patient stories, analyzing literary texts, and engaging in reflective writing after the workshop. They also expressed significantly higher levels of agreement that engaging in literary analysis and reflective writing could improve patient care, reduce provider burnout, and strengthen connectedness with colleagues. Qualitative analysis demonstrated that participants found the sessions to be worthwhile and appreciated how narrative medicine could enhance their medical practice. Conclusions Incorporating a brief narrative medicine curriculum into an internal medicine residency program is both feasible and valuable. A single narrative medicine session was practical and well-received by residents, as it promoted self-reflection, observational skills, and connection with colleagues. Future workshops should be customized for different training levels and residency tracks, and additional studies should evaluate whether the outcomes persist over time.

A Case of Tizanidine Withdrawal and Road to Recovery

This case report highlights the complexities of tizanidine withdrawal in a 68-year-old woman with chronic pain. Tizanidine, a widely used imidazole-derived muscle relaxant, poses challenges due to the absence of standardized withdrawal protocols. The patient's presentation included hypertension and tachycardia following a gradual reduction in her outpatient tizanidine dose. During the de-escalation of tizanidine, the patient experienced withdrawal symptoms, including severe body aches, hypertension, and tachycardia. Management during withdrawal involved a unique approach using a one-time dose of phenobarbital, a measure that allowed the resolution of hemodynamic instability and pain with complete discontinuation of tizanidine. The ultimate decision to transition the patient to methocarbamol and stop taking tizanidine for pain control highlights the importance of individualized care. The patient has responded to this therapy upon follow-up.

An Opportunity for Change: Principles for Reforming Internal Medicine Inpatient Conferences

Inpatient educational conferences are a key part of internal medicine residency training. Many residencies made conferences virtual during the COVID-19 pandemic, and are now returning to in-person sessions. As we navigate this change, we can seize this opportunity to re-evaluate the role that inpatient conferences serve in resident education. In this paper, we briefly review the history of inpatient educational conferences before offering five recommendations for improvement. Our recommendations include grounding conference formats in educational theory, leveraging the expertise of all potential educators, broadening content to include health equity and justice throughout all curricula, and explicitly focusing on cultivating community among participants. Recognizing that each residency program is different, we anticipate that these recommendations may be implemented differently based on program size, available resources, and current institutional practices. We also include examples of prior successful curricular reforms aligned with our principles. We hope these recommendations ensure inpatient conferences continue to be a central part of residency education for future generations of internal medicine residents.

The Impact of an Intern's Clinical Guidebook on Easing the Transition of New Interns Into the United States Healthcare System

This study explores the efficacy of an intern's clinical guidebook in facilitating the transition of categorical internal medicine interns into the United States healthcare system. New interns, particularly foreign medical graduates, face multifaceted challenges during their initial year of residency. The research, conducted at Ascension Saint Joseph Hospital in Chicago, employed a quasi-experimental pre-post design involving 20 interns. Participants were provided with an intern's clinical guidebook, and their knowledge was assessed through pre and post exams. Results demonstrated a statistically significant improvement in overall knowledge, with mean scores increasing from 65% to 77.37%. Subgroup analysis revealed similar improvements among both male and female interns. Data confidentiality and ethical considerations were prioritized, with participant data anonymized and stored securely. Despite limitations, this study highlights the guidebook's potential to enhance intern education and improve the quality of care provided during the crucial transition period. Further research is recommended to validate and extend these findings.

Mid-ventricular Takotsubo Cardiomyopathy With Coexisting Myocardial Bridge

Typical takotsubo cardiomyopathy (TCM) is a reversible form of myocardial injury that presents with a characteristic ballooning abnormality of the left ventricular apex. Typical TCM has been associated with myocardial bridging; however, mid-ventricular variant TCM has not. We describe a rare case of mid-ventricular variant TCM with a coexisting left anterior descending artery myocardial bridge and discuss management strategies. Furthermore, we propose potential pathophysiological mechanisms that may contribute to the symptomatic presentation of both conditions as a manifestation of common etiological factors.

The patient's journey includes neurological dysfunction, renal failure, and clinical complexities, showcasing the rarity of these overlapping conditions. The report explains the diagnostic process, clinical and laboratory findings, specialty consultations, and treatment decisions leading to the diagnosis of SLE with features of MAS overlapping with HLH. By offering insights into the latest research and clinical perspectives, this case report contributes to a deeper understanding of these disorders, aiming to guide clinicians in recognizing and managing such intricate cases effectively.

Do Laboratory Blood Tests Change Medical Care in Patients Hospitalized with Community-Acquired Pneumonia?

Background and Objectives: The prevalence of inappropriate laboratory testing is believed to be high, but only a limited number of studies have reviewed medical charts to determine whether tests impact medical care. Materials and Methods: From the electronic database, we selected 500 consecutive patients with community-acquired pneumonia who were hospitalized between January 2020 and October 2021. We excluded eight patients who had COVID-19, but were not identified in the database, and were only identified after chart review. To assess the impact of tests on medical care, we conducted a thorough review of the patients' charts. Results: The age of the patients was 78 ± 16 years, with 42.3% female (n = 208) hospitalized for a median of 4 days (25-75%, 3-6 days). There were 27957 laboratory test results during 2690 hospital days (10.4 tests per day of hospitalization). Of the 2997 tests carried out on admission 5.7% (n = 170) resulted in changes of medical care in 34.5% (170/492) of the patients, nearly all from the results of electrolytes, renal function tests, and serum glucose measurements. Tests that did not lead to any decision on medical care included 75.8% (7181/9478) on admission and 86.0% (15,898/18,479) on repetitive testing, i.e., repetitive testing accounted for 68.9% (15,898/23,079) of tests that did not change medical care. By excluding tests that did not change medical care, the overall testing rate would decrease by 82.6% (23,079/27,947), and from 10.4 tests per day to 2.1 tests per day. Conclusions: We conclude that the estimate of the overuse of laboratory testing, which includes all testing that does not change patient care, is much higher than reported using other methodologies. Most of the overuse was from repetitive testing that included unnecessary testing in patients without admission test results that changed medical care. Further investigation is needed to determine if these findings can be applied to patients with diverse health conditions and in different healthcare settings.

Japanese Internists' Most Memorable Diagnostic Error Cases: A Self-reflection Survey

Objective The etiologies of diagnostic errors among internal medicine physicians are unclear. To understand the causes and characteristics of diagnostic errors through reflection by those involved in them. Methods We conducted a cross-sectional study using a web-based questionnaire in Japan in January 2019. Over a 10-day period, a total of 2,220 participants agreed to participate in the study, of whom 687 internists were included in the final analysis. Participants were asked about their most memorable diagnostic error cases, in which the time course, situational factors, and psychosocial context could be most vividly recalled and where the participant provided care. We categorized diagnostic errors and identified contributing factors (i.e., situational factors, data collection/interpretation factors, and cognitive biases). Results Two-thirds of the identified diagnostic errors occurred in the clinic or emergency department. Errors were most frequently categorized as wrong diagnoses, followed by delayed and missed diagnoses. Errors most often involved diagnoses related to malignancy, circulatory system disorders, or infectious diseases. Situational factors were the most cited error cause, followed by data collection factors and cognitive bias. Common situational factors included limited consultation during office hours and weekends and barriers that prevented consultation with a supervisor or another department. Conclusion Internists reported situational factors as a significant cause of diagnostic errors. Other factors, such as cognitive biases, were also evident, although the difference in clinical settings may have influenced the proportions of the etiologies of the errors that were observed. Furthermore, wrong, delayed, and missed diagnoses may have distinctive associated cognitive biases.

Bedside Clinical Hand-held Ultrasound in an Internal Medicine Department: The "Bed Med-Us" Experience of Codogno and its Clinical Utility in the Management of Diagnosis and Therapy in 1007 Patients

Purpose Handheld ultrasound (HH-US) answers simple clinical questions in emergencies. We performed conventional US with HH-US at the patient's bedside (BED) during a medical visit (MED) (BED MED-US). The purpose of this prospective study is to estimate BED MED-US reliability, its clinical impact in helping the clinician to formulate correct diagnoses, and its ability to save time and money. Materials and Methods 1007 patients (519 M; age:76.42) were assessed (from March 2021 to November 2022) in one or more districts. Final diagnosis was determined with clinical and reference tests (chest RX/CT, abdominal CT, endoscopy, etc.). Sensitivity, specificity, LR+ and LR-, and corresponding AUROC were evaluated. HH-US diagnoses were classified as: confirmation (HH-US revealed the sonographic signs that confirmed the clinical diagnosis) (CO), exclusion (HH-US excluded the presence of the ultrasound signs of other pathologies, in the clinical differential diagnosis) (EX), etiological (HH-US reaches diagnosis in clinically doubtful cases) (ET), or clinically relevant incidental (HH-US diagnoses that change the patient's process completely) (INC). Results HH-US reliability: true-pos: 752; true-neg: 242; false-pos: 7; false-neg: 6 (sens: 99.1%, spec: 97.6%, LR+: 98.5; LR-: 00.15, AUROC: 0.997); clinical impact: CO-diagnosis: 21%; EX: 25%; ET: 47%; INC: 7%; saved time and money: approximately 35,572 minutes of work and 9324 euros. Conclusion BED MED-US is a reliable clinical imaging system, with an important clinical impact both in diagnosis (etiological in 47%, incidental in 7%) and in the management of personnel resources.

A qualitative analysis of internal medicine residents' experience with substance use disorder education and training: a pilot study

BACKGROUND

Lack of education and training on caring for patients with substance use disorder (SUD) is common among healthcare providers, often resulting in clinicians feeling unprepared to treat patients with SUD.

OBJECTIVES

This study explored resident physicians' experiences with SUD education throughout medical school and residency and qualitatively evaluated whether a SUD initiative improved resident's knowledge and efficacy of treating various SUDs.

METHODS

We implemented a brief (seven hours total) educational initiative focused on treating SUDs virtually over the course of an academic year for residents enrolled in the University of Southern California Internal Medicine Residency program. Semi-structured interviews were conducted with residents after completion of the initiative. A thematic analysis was conducted to identify common themes that emerged from the qualitative data.

RESULTS

Every resident noted receiving insufficient training for the treatment of SUDs prior to the initiative. The initiative was viewed favorably, and participants particularly appreciated having an introduction to prescribing medication for the treatment of SUD such as buprenorphine. Despite the perceived success of the initiative in increasing awareness of treatment modalities for SUD, residents expressed a lack of comfort in handling SUD cases and desired additional practical lectures and application of knowledge through increased experiential training.

CONCLUSIONS

SUD education and training appears to be a useful constituent of resident training and should be included in the standard curriculum and rotations. Residency programs should consider including formal education, hands-on practice, and providing adequate resources for residents to develop their capabilities to care for patients with SUD.

Understanding Primary Care Physician Perspectives on the Diagnosis and Management of Non-Alcoholic Fatty Liver Disease: A Qualitative Study

Primary care physicians (PCPs) are well suited to manage patients with non-alcoholic fatty liver disease (NAFLD), but the limited, existing research suggests inadequate knowledge about the natural history, diagnostic methods, and management of NAFLD. The purpose of this qualitative study is to further understand the knowledge and practices for the diagnosis and management of NAFLD among PCPs. We conducted in-depth interviews with PCPs in the Greater Houston area, addressing current clinical practices used for diagnosing and managing NAFLD, as well as the perceptions of the PCPs regarding the burden of NAFLD on patients. We recorded interviews, transcribed them, coded transcripts, and identified patterns and themes. The interviewed PCPs (n = 16) were from internal or family medicine, with a range of experience (1.5-30 years). We found variations in NAFLD diagnosis and management across practices and by insurance status. Patients with abnormal liver imaging who had insurance or were within a safety-net healthcare system were referred by PCPs to specialists. Uninsured patients with persistently elevated liver enzymes received lifestyle recommendations from PCPs without confirmatory imaging or specialist referral. The role of PCPs in NAFLD management varied, with some helping patients set dietary and physical activity goals while others provided only general recommendations and/or referred patients to a dietitian. The diagnosis and management of NAFLD vary widely among PCPs and may be impacted by patients' insurance status and clinic-specific practices. The increasing burden of NAFLD in the U.S. medical system highlights the need for more PCPs involvement in managing NAFLD.

Integrating behavioural health and primary care: qualitative findings on contextual factors that influence integration

BACKGROUND

Integrating behavioural health care into primary care practices may increase patients' access to behavioural health services and improve health outcomes. However, few studies have explored factors that influence integration processes.

OBJECTIVE

We sought to better understand contextual factors that support or impede behavioural health integration in primary care practices.

METHODS

We conducted 71 semi-structured interviews with providers, staff, and leaders from eight primary care practices in the United States with integrated behavioural health services, which were participating in a randomized control, pragmatic trial: Integrating Behavioural Health and Primary Care. Practices were selected for diversity on geographic location, size, ownership, and experience with integration. We conducted a thematic analysis of the qualitative data derived from the interviews.

RESULTS

We identified four categories of contextual factors influencing behavioural health integration: leadership commitment to integration, financial considerations, workflow and communication systems, and providers' perspectives on integration and team-based healthcare. Supportive factors included leaders' commitment to integration, adequate staffing, customized communication and workflow systems, collaborative practice culture, and healthy working relationships amongst providers. Impediments included staffing issues and payment models that do not reimburse for activities required to support integrated care.

CONCLUSION

Interviewees described various benefits of integration, including providers feeling better equipped to address patients' needs due to collaboration between medical and behavioural providers and resulting interdisciplinary learning. Given concerns about provider burnout, this finding warrants further study.

Pharmaceutical Agents as Potential Drivers in the Development of Early-Onset Colorectal Cancer: Case-Control Study

BACKGROUND

The incidence of early-onset colorectal cancer (EOCRC) rose abruptly in the mid 1990s, is continuing to increase, and has now been noted in many countries. By 2030, 25% of American patients diagnosed with rectal cancer will be 49 years or younger. The large majority of EOCRC cases are not found in patients with germline cancer susceptibility mutations (eg, Lynch syndrome) or inflammatory bowel disease. Thus, environmental or lifestyle factors are suspected drivers. Obesity, sedentary lifestyle, diabetes mellitus, smoking, alcohol, or antibiotics affecting the gut microbiome have been proposed. However, these factors, which have been present since the 1950s, have not yet been conclusively linked to the abrupt increase in EOCRC. The sharp increase suggests the introduction of a new risk factor for young people. We hypothesized that the driver may be an off-target effect of a pharmaceutical agent (ie, one requiring regulatory approval before its use in the general population or an off-label use of a previously approved agent) in a genetically susceptible subgroup of young adults. If a pharmaceutical agent is an EOCRC driving factor, regulatory risk mitigation strategies could be used.

OBJECTIVE

We aimed to evaluate the possibility that pharmaceutical agents serve as risk factors for EOCRC.

METHODS

We conducted a case-control study. Data including demographics, comorbidities, and complete medication dispensing history were obtained from the electronic medical records database of Maccabi Healthcare Services, a state-mandated health provider covering 26% of the Israeli population. The participants included 941 patients with EOCRC (≤50 years of age) diagnosed during 2001-2019 who were density matched at a ratio of 1:10 with 9410 control patients. Patients with inflammatory bowel disease and those with a known inherited cancer susceptibility syndrome were excluded. An advanced machine learning algorithm based on gradient boosted decision trees coupled with Bayesian model optimization and repeated data sampling was used to sort through the very high-dimensional drug dispensing data to identify specific medication groups that were consistently linked with EOCRC while allowing for synergistic or antagonistic interactions between medications. Odds ratios for the identified medication classes were obtained from a conditional logistic regression model.

RESULTS

Out of more than 800 medication classes, we identified several classes that were consistently associated with EOCRC risk across independently trained models. Interactions between medication groups did not seem to substantially affect the risk. In our analysis, drug groups that were consistently positively associated with EOCRC included beta blockers and valerian (Valeriana officinalis). Antibiotics were not consistently associated with EOCRC risk.

CONCLUSIONS

Our analysis suggests that the development of EOCRC may be correlated with prior use of specific medications. Additional analyses should be used to validate the results. The mechanism of action inducing EOCRC by candidate pharmaceutical agents will then need to be determined.

"Two Years Later I'm Still Just as Angry": A Focus Group Study of Emergency and Internal Medicine Physicians on Disrespectful Communication

Phenomenon: Disrespectful behavior between physicians across departments can contribute to burnout, poor learning environments, and adverse patient outcomes. Approach: In this focus group study, we aimed to describe the nature and context of perceived disrespectful communication between emergency and internal medicine physicians (residents and faculty) at patient handoff. We used a constructivist approach and framework method of content analysis to conduct and analyze focus group data from 24 residents and 11 faculty members from May to December 2019 at a large academic medical center. Findings: We organized focus group results into four overarching categories related to disrespectful communication: characteristics and context (including specific phrasing that members from each department interpreted as disrespectful, effects of listener engagement/disengagement, and the tendency for communication that is not in-person to result in misunderstanding and conflict); differences across training levels (with disrespectful communication more likely when participants were at different training levels); the individual correspondent's tendency toward perceived rudeness; and negative/long-term impacts of disrespectful communication on the individual and environment (including avoidance and effects on patient care). Insights: In the context of predominantly positive descriptions of interdepartmental communication, participants described episodes of perceived disrespectful behavior that often had long-lasting, negative impacts on the quality of the learning environment and clinical work. We created a conceptual model illustrating the process and outcomes of these interactions. We make several recommendations to reduce disrespectful communication that can be applied throughout the hospital to potentially improve patient care, interdepartmental collaboration, and trainee and faculty quality of life.

Acute Generalized Exanthematous Pustulosis in a Hemodialysis Patient

Acute generalized exanthematous pustulosis (AGEP) is an uncommon skin condition that should be considered when evaluating patients with severe skin eruptions accompanied by systemic symptoms. We present a woman in her 70s with end-stage renal disease on hemodialysis who developed a generalized pruritic rash seven days after the administration of pre-procedure vancomycin and acetaminophen. Our patient underwent a biopsy with findings consistent with AGEP. This report highlights the need to consider AGEP in patients with severe cutaneous eruptions and systemic involvement. Prompt biopsy and blood cultures are essential to prevent misdiagnosis and treatment delays.
