Antibiotic Prescribing Patterns for Respiratory Tract Illnesses Following the Conclusion of an Education and Feedback Intervention in Primary Care.

BACKGROUND: A study previously conducted in primary care practices found that implementation of an educational session and peer comparison feedback was associated with reduced antibiotic prescribing for respiratory tract diagnoses (RTDs). Here, we assess the long-term effects of this intervention on antibiotic prescribing following cessation of feedback. METHODS: RTD encounters were grouped into tiers based on antibiotic prescribing appropriateness: tier 1, almost always indicated; tier 2, possibly indicated; and tier 3, rarely indicated. A χ2 test was used to compare prescribing between 3 time periods: pre-intervention, intervention, and post-intervention (14 months following cessation of feedback). A mixed-effects multivariable logistic regression analysis was performed to assess the association between period and prescribing. RESULTS: We analyzed 260 900 RTD encounters from 29 practices. Antibiotic prescribing was more frequent in the post-intervention period than in the intervention period (28.9% vs 23.0%, P < .001) but remained lower than the 35.2% pre-intervention rate (P < .001). In multivariable analysis, the odds of prescribing were higher in the post-intervention period than the intervention period for tier 2 (odds ratio [OR], 1.19; 95% confidence interval [CI]: 1.10-1.30; P < .05) and tier 3 (OR, 1.20; 95% CI: 1.12-1.30) indications but was lower compared to the pre-intervention period for each tier (OR, 0.66; 95% CI: 0.59-0.73 tier 2; OR, 0.68; 95% CI: 0.61-0.75 tier 3). CONCLUSIONS: The intervention effects appeared to last beyond the intervention period. However, without ongoing provider feedback, there was a trend toward increased prescribing. Future studies are needed to determine optimal strategies to sustain intervention effects.

Improving Outpatient Antibiotic Prescribing for Respiratory Tract Infections in Primary Care: A Stepped-Wedge Cluster Randomized Trial.

BACKGROUND: Inappropriate antibiotic prescribing is common in primary care (PC), particularly for respiratory tract diagnoses (RTDs). However, the optimal approach for improving prescribing remains unknown. METHODS: We conducted a stepped-wedge study in PC practices within a health system to assess the impact of a provider-targeted intervention on antibiotic prescribing for RTDs. RTDs were grouped into tiers based on appropriateness of antibiotic prescribing: tier 1 (almost always indicated), tier 2 (may be indicated), and tier 3 (rarely indicated). Providers received education on appropriate RTD prescribing followed by monthly peer comparison feedback on antibiotic prescribing for (1) all tiers and (2) tier 3 RTDs. A χ 2 test was used to compare the proportion of visits with antibiotic prescriptions before and during the intervention. Mixed-effects multivariable logistic regression analysis was performed to assess the association between the intervention and antibiotic prescribing. RESULTS: Across 30 PC practices and 185 755 total visits, overall antibiotic prescribing was reduced with the intervention, from 35.2% to 23.0% of visits (P < .001). In multivariable analysis, the intervention was associated with a reduced odds of antibiotic prescription for tiers 2 (odds ratio [OR] 0.57; 95% confidence interval [CI] .52-.62) and 3 (OR 0.57; 95% CI .53-.61) but not for tier 1 (OR 0.98; 95% CI .83-1.16). CONCLUSIONS: A provider-focused intervention reduced overall antibiotic prescribing for RTDs without affecting prescribing for infections that likely require antibiotics. Future research should examine the sustainability of such interventions, potential unintended adverse effects on patient health or satisfaction, and provider perceptions and acceptability.

Echocardiography and cardiac MRI in mutation-negative hypertrophic cardiomyopathy in an older patient: a case defining the need for ICD.

We report the case of a 67-year-old man with hypertrophic cardiomyopathy who presented for a second opinion about implantable cardio-defibrillator (ICD) placement after a witnessed syncopal episode. Despite his older age, being mutation-negative, and having a maximal septal thickness of 2.2 cm on echocardiography, he demonstrated rapid progression of myocardial fibrosis on cardiac MRI, correlating to ventricular tachyarrhythmias and syncope. We review the role of echocardiography and cardiac MRI in optimizing medical care for such patients who may not otherwise meet criteria for an ICD placement or further interventions.

Racial differences in glucose control among patients with type 2 diabetes: a survey on dietary temptations, coping, and trust in physicians.

OBJECTIVE: A quantitative evaluation of self-care behaviors, psychosocial stressors, and patient relationships to health care to better understand racial disparities in these domains. RESEARCH DESIGN AND METHODS: A cross-sectional study of adult patients with type 2 diabetes in University of Pennsylvania Healthcare System who had a HbA1c test within one month of survey administration. The survey instrument included among other items, the Dieter's Inventory of Eating Temptations Self-Efficacy instrument (DIET-SE), the Jalowiec Coping Scale (JCS), and the Trust in Physician (TIP) scale. RESULTS: 332 individuals completed the survey. Poor glucose control was significantly associated with Black race, lower income level, other demographic variables, non-perfect medication adherence, and poorer diet quality. It was also associated with lower self-efficacy to resist social dietary temptations, and among White patients it was associated was decreased use of a confrontive coping style. However, these factors did not explain the racial differences in glucose control between Blacks and Whites. CONCLUSIONS: Interventions aimed at dietary temptations, coping styles, or trust in physicians may not reduce racial disparities in glucose control. However, interventions that focus on dietary temptations may positively affect all diabetic patients.

Analysis of seasonal variation of antibiotic prescribing for respiratory tract diagnoses in primary care practices.

Objective: To determine antibiotic prescribing appropriateness for respiratory tract diagnoses (RTD) by season. Design: Retrospective cohort study. Setting: Primary care practices in a university health system. Patients: Patients who were seen at an office visit with diagnostic code for RTD. Methods: Office visits for the entire cohort were categorized based on ICD-10 codes by the likelihood that an antibiotic was indicated (tier 1: always indicated; tier 2: sometimes indicated; tier 3: rarely indicated). Medical records were reviewed for 1,200 randomly selected office visits to determine appropriateness. Based on this reference standard, metrics and prescriber characteristics associated with inappropriate antibiotic prescribing were determined. Characteristics of antibiotic prescribing were compared between winter and summer months. Results: A significantly greater proportion of RTD visits had an antibiotic prescribed in winter [20,558/51,090 (40.2%)] compared to summer months [11,728/38,537 (30.4%)][standardized difference (SD) = 0.21]. A significantly greater proportion of winter compared to summer visits was associated with tier 2 RTDs (29.4% vs 23.4%, SD = 0.14), but less tier 3 RTDs (68.4% vs 74.4%, SD = 0.13). A greater proportion of visits in winter compared to summer months had an antibiotic prescribed for tier 2 RTDs (80.2% vs 74.2%, SD = 0.14) and tier 3 RTDs (22.9% vs 16.2%, SD = 0.17). The proportion of inappropriate antibiotic prescribing was higher in winter compared to summer months (72.4% vs 62.0%, P < .01). Conclusions: Increases in antibiotic prescribing for RTD visits from summer to winter were likely driven by shifts in diagnoses as well as increases in prescribing for certain diagnoses. At least some of this increased prescribing was inappropriate.

The Penn Medicine COVID-19 Therapeutics Committee-Reflections on a Model for Rapid Evidence Review and Dynamic Practice Recommendations During a Public Health Emergency.

The Penn Medicine COVID-19 Therapeutics Committee-an interspecialty, clinician-pharmacist, and specialist-front line primary care collaboration-has served as a forum for rapid evidence review and the production of dynamic practice recommendations during the 3-year coronavirus disease 2019 public health emergency. We describe the process by which the committee went about its work and how it navigated specific challenging scenarios. Our target audiences are clinicians, hospital leaders, public health officials, and researchers invested in preparedness for inevitable future threats. Our objectives are to discuss the logistics and challenges of forming an effective committee, undertaking a rapid evidence review process, aligning evidence-based guidelines with operational realities, and iteratively revising recommendations in response to changing pandemic data. We specifically discuss the arc of evidence for corticosteroids; the noble beginnings and dangerous misinformation end of hydroxychloroquine and ivermectin; monoclonal antibodies and emerging viral variants; and patient screening and safety processes for tocilizumab, baricitinib, and nirmatrelvir-ritonavir.

Development and validation of antibiotic stewardship metrics for outpatient respiratory tract diagnoses and association of provider characteristics with inappropriate prescribing.

OBJECTIVE: To determine metrics and provider characteristics associated with inappropriate antibiotic prescribing for respiratory tract diagnoses (RTDs). DESIGN: Retrospective cohort study. SETTING: Primary care practices in a university health system. PARTICIPANTS: Patients seen by an attending physician or advanced practice provider (APP) at their primary care office visit with International Classification of Disease, Tenth Revision, Clinical Modification (ICD-10-CM)-coded RTDs. METHODS: Medical records were reviewed for 1,200 randomly selected office visits in which an antibiotic was prescribed to determine appropriateness. Based on this gold standard, metrics and provider characteristics associated with inappropriate antibiotic prescribing were determined. RESULTS: Overall, 69% of antibiotics were inappropriate. Metrics utilizing prespecified RTDs most strongly associated with inappropriate prescribing were (1) proportion prescribing for RTDs for which antibiotics are almost never required (eg, bronchitis) and (2) proportion prescribing for any RTD. Provider characteristics associated with inappropriate antibiotic prescribing were APP versus physician (72% vs 58%; P = .02), family medicine versus internal medicine (76% vs 63%; P = .01), board certification 1997 or later versus board certification before 1997 (75% vs 63%; P = .02), nonteaching versus teaching practice (73% vs 51%; P < .01), and nonurban vs urban practice (77% vs 57%; P < .01). CONCLUSIONS: Metrics utilizing proportion prescribing for RTDs for which antibiotics are almost never required and proportion prescribing for any RTD were most strongly associated with inappropriate prescribing. APPs and clinicians with family medicine training, with board certification 1997 or later, and who worked in nonteaching or nonurban practices had higher proportions of inappropriate prescribing. These findings could inform design of interventions to improve prescribing and could represent an efficient way to track inappropriate prescribing.

Development of a Multifaceted Antimicrobial Stewardship Curriculum for Undergraduate Medical Education: The Antibiotic Stewardship, Safety, Utilization, Resistance, and Evaluation (ASSURE) Elective.

To address the growing need for dedicated stewardship training in undergraduate medical education, we developed an antimicrobial stewardship curriculum for medical students with the objectives of increasing expertise in antimicrobial prescribing, introducing antimicrobial stewardship fundamentals, and enhancing comfort with engagement in interprofessional antimicrobial stewardship activities.

A randomized controlled study of convalescent plasma for individuals hospitalized with COVID-19 pneumonia.

BackgroundAntibody-based strategies for COVID-19 have shown promise in prevention and treatment of early disease. COVID-19 convalescent plasma (CCP) has been widely used but results from randomized trials supporting its benefit in hospitalized patients with pneumonia are limited. Here, we assess the efficacy of CCP in severely ill, hospitalized adults with COVID-19 pneumonia.MethodsWe performed a randomized control trial (PennCCP2), with 80 adults hospitalized with COVID-19 pneumonia, comparing up to 2 units of locally sourced CCP plus standard care versus standard care alone. The primary efficacy endpoint was comparison of a clinical severity score. Key secondary outcomes include 14- and 28-day mortality, 14- and 28-day maximum 8-point WHO ordinal score (WHO8) score, duration of supplemental oxygenation or mechanical ventilation, respiratory SARS-CoV-2 RNA, and anti-SARS-CoV-2 antibodies.ResultsEighty hospitalized adults with confirmed COVID-19 pneumonia were enrolled at median day 6 of symptoms and day 1 of hospitalization; 60% were anti-SARS-CoV-2 antibody seronegative. Participants had a median of 3 comorbidities, including risk factors for severe COVID-19 and immunosuppression. CCP treatment was safe and conferred significant benefit by clinical severity score (median [MED] and interquartile range [IQR] 10 [5.5-30] vs. 7 [2.75-12.25], P = 0.037) and 28-day mortality (n = 10, 26% vs. n = 2, 5%; P = 0.013). All other prespecified outcome measures showed weak evidence toward benefit of CCP.ConclusionTwo units of locally sourced CCP administered early in hospitalization to majority seronegative participants conferred a significant benefit in clinical severity score and 28-day mortality. Results suggest CCP may benefit select populations, especially those with comorbidities who are treated early.Trial RegistrationClinicalTrials.gov NCT04397757.FundingUniversity of Pennsylvania.

Use of Fellow as Clinical Teacher (FACT) Curriculum for Teaching During Consultation: Effect on Subspecialty Fellow Teaching Skills.

BACKGROUND: Subspecialty consultation in inpatient care is increasing. Teaching by subspecialty fellows in a consultation setting may be an important source of work-based learning for students and residents. However, teaching and evaluation of learners in this context may be challenging due to personal and systems-based barriers. OBJECTIVE: We developed and evaluated a framework designed to overcome barriers to teaching and to improve fellow teaching skills during inpatient consultation. METHODS: The PARTNER (Partner with resident, Assess the learner, Reinforce positives, Teaching objectives, New knowledge, Execute recommendations, Review) framework was delivered to rheumatology and pulmonary and critical care medicine fellows at 3 academic medical centers as part of a 2-session Fellow as Clinical Teacher (FACT) curriculum. Fellows' teaching skills were evaluated using an objective structured teaching exercise (OSTE) pre- and postcurriculum, and at the end of the academic year. Self-assessment surveys were used to evaluate fellows' self-perception of teaching skills. RESULTS: Twelve of 16 eligible fellows (75%) participated in the program and completed 73 OSTE cases. Teaching skills measured by OSTEs and self-assessment surveys improved after administration of the FACT curriculum. There was no significant skill decay at the end-of-year evaluation. The curriculum was rated highly, and 73% (8 of 11) of fellows stated they would teach more frequently as a result of the intervention. CONCLUSIONS: The FACT curriculum was practical and feasible, and significantly improved fellows' teaching skills teaching during inpatient consultation.

Human Immunodeficiency Virus in Kidney Transplantation.

Patients infected with human immunodeficiency virus (HIV) are living longer, healthier lives on highly active antiretroviral therapy and, as a result, interest in kidney transplantation for HIV-infected patients with end-stage renal disease has increased. HIV is no longer considered a contraindication to solid-organ transplantation and the number of kidney transplants performed in HIV-infected patients each year is increasing steadily. HIV-infected kidney transplant recipients have had excellent outcomes overall, but there are still significant challenges, including high rates of acute rejection, drug-drug interactions, and poor outcomes in patients co-infected with hepatitis C virus. The gap between supply and demand for organs remains a challenge but new developments in HIV-positive to HIV-positive kidney transplantation may help bridge this gap.
