Background Internal medicine (IM) resident physicians spend a considerable amount of time managing their inbox as part of their longitudinal continuity clinic experience. There are no standardized guidelines for how programs should train, monitor, or supervise residents in this type of patient care. Objective To understand how IM residency programs educate, monitor, and supervise resident electronic health record (EHR) inbox management as part of their longitudinal continuity clinic and determine whether patient safety events have occurred due to EHR inbox-related patient care decisions made by unsupervised resident physicians. Methods In August 2021, 439 program directors at accredited US IM residency programs who were members of the Association of Program Directors in Internal Medicine (APDIM) were asked 12 questions developed by the study authors and APDIM survey committee members regarding resident EHR inbox management as part of the annual APDIM survey. Results Two hundred and sixty-seven (61%) PDs responded. The majority (224 of 267, 84%) of programs provided guidelines for expected message response times; less than half (115, 43%) monitored timeliness metrics. Only half (135; 51%) of programs required faculty supervision of inbox messages for all residents; 28% (76) did not require supervision for any residents. Twenty-one percent of PDs (56) reported awareness of a patient safety event occurring due to an unsupervised resident inbox-related patient care decision. Conclusions Substantial variability exists in how IM residency programs train, monitor, supervise, and provide coverage for resident inbox work. Program directors are aware of patient safety events resulting from unsupervised resident inbox management.

Abstract Background Acute hematogenous osteomyelitis (AHO) is a relatively infrequent but significant infection in pediatric patients. As Staphylococcus aureus is the most common cause of AHO, intravenous and oral first-generation cephalosporins are common therapies. Cephalexin is a commonly prescribed oral therapy for pediatric AHO, although it requires frequent dosing that may affect adherence. Cefadroxil is a comparable oral first-generation cephalosporin with a more desirable dosing schedule. Methods We reviewed pediatric patients admitted to Mayo Clinic between March 2002 and September 2020 for management of AHO who received treatment with a first-generation cephalosporin. We reviewed timing of oral therapy transition, therapy-associated adverse effects, and recurrence of disease after completion of therapy. Results There were 59 patients included in the study. There was similar occurrence of adverse effects in patients receiving cefadroxil and cephalexin, although use of cefadroxil coincided with more gastrointestinal adverse effects and leukopenia and use of cephalexin with more rash and neutropenia. One secondary treatment failure occurred in our study, in a patient receiving cephalexin for treatment of septic arthritis. Conclusions Cefadroxil may be a reasonable alternative oral therapy for methicillin-susceptible S aureus or culture-negative AHO in pediatric patients, particularly when a less frequent dosing schedule is desired. Future study with a larger sample size is warranted.

Abstract Introduction: People from backgrounds that are economically/socially disadvantaged experienced disproportionately high COVID-19 death rates and had lower vaccination rates. Effective outreach strategies for increasing vaccine uptake during the pandemic are not fully known. Among patients receiving care at a Federally Qualified Health Center, we tested whether community engaged digitally-enabled outreach increased COVID vaccine uptake. Study Design, Setting, and Participants: A 3-parallel-arm randomized controlled trial with a hybrid effectiveness-implementation design was conducted among patients ≥18 years old on study enrollment during 2021 with 1,650 assigned in 3:10:20 ratio; 2,328 were later selected for two subsequent implementation rounds. Interventions: From April 13 to June 10, 2021, patients were proactively sent a text-messaging invitation to make an appointment for vaccination as part of the routine practice (Arm 1, n=150) with added personalized clinician recommendation alone (Arm 2, n=500) or with an explicit nudge for answers to frequently asked questions (Arm 3, n=1,000). Further implementation used messaging addressing vaccine hesitancy (n=1,323) or adverse reactions to vaccines (n=1,005). Main Outcomes and Measures: The primary outcome was the completion of the first SARS-Cov-2 vaccine dose determined at 14, 30 and 90 days after outreach. Results: Of 1,650 patients in effectiveness Arms, 61% was female. Vaccination rates for Arms 1, 2, and 3, were 6% (n=9), 5.4% (n=27) and 3.3% (n=33) at 14 days, and 11.5% (n=17), 11.6% (n=58), and 8.5% (n=85) at 90 days, respectively, which were similar in pairwise comparisons. At 90 days, vaccination rates were similar across the two implementation rounds (3.9% vs. 3.6%) and were similar to the rate (3.3%) among patients who were not selected for intervention arms or implementation rounds (n=8,671). Conclusions: Digitally-enabled outreach that included SMS messaging outreach augmented with clinician recommendations did not improve COVID-19 vaccination rates.

Abstract Venetoclax + hypomethylating agent (Ven‐HMA) is currently the standard frontline therapy for older/unfit patients with newly diagnosed acute myeloid leukemia (ND‐AML). Our objective in the current retrospective study of 301 adult patients (median age 73 years; 62% de novo) with ND‐AML was to identify molecular predictors of treatment response to Ven‐HMA and survival; European LeukemiaNet (ELN) genetic risk assignment was favorable 15%, intermediate 16%, and adverse 69%. Complete remission, with (CR) or without (CRi), count recovery, was documented in 182 (60%) patients. In multivariable analysis, inclusive of mutations only, “favorable” predictors of CR/CRi were NPM1 (86% vs. 56%), IDH2 (80% vs. 58%), and DDX41 (100% vs. 58%) and “unfavorable” TP53 (40% vs. 67%), FLT3‐ ITD (36% vs. 63%), and RUNX1 (44% vs. 64%) mutations; significance was sustained for each mutation after adjustment for age, karyotype, and therapy‐related qualification. CR/CRi rates ranged from 36%, in the presence of unfavorable and absence of favorable mutation, to 91%, in the presence of favorable and absence of unfavorable mutation. At median follow‐up of 8.5 months, 174 deaths and 41 allogeneic stem cell transplants (ASCT) were recorded. In multivariable analysis, risk factors for inferior survival included failure to achieve CR/CRi (HR 3.4, 95% CI 2.5–4.8), adverse karyotype (1.6, 1.1–2.6), TP53 mutation (1.6, 1.0–2.4), and absence of IDH2 mutation (2.2, 1.0–4.7); these risk factors were subsequently applied to construct an HR‐weighted risk model that performed better than the ELN genetic risk model (AIC 1661 vs. 1750): low ( n = 130; median survival 28.9 months), intermediate ( n = 105; median 9.6 months), and high ( n = 66; median 3.1 months; p < .001); survival in each risk category was significantly upgraded by ASCT. The current study identifies genotype signatures for predicting response and proposes a 3‐tiered, CR/CRi‐based, and genetics‐enhanced survival model for AML patients receiving upfront therapy with Ven‐HMA.

Introduction Hereditary hemorrhagic telangiectasia (HHT), the second most common bleeding disorder worldwide, affects 1 in 5000 people and is characterized by extensive formation of telangiectasia and arteriovenous malformations (AVM) in mucosa, lung, brain, and liver. The primary clinical manifestation is recurrent, often severe epistaxis which commonly results in iron deficiency anemia, emergency room visits, hospitalizations, and reduced quality of life (QOL). Though non-randomized and/or underpowered studies have suggested that systemic bevacizumab or thalidomide may be effective in treating HHT, there have been no pivotal studies and therefore no FDA or EMA approved therapies. Methods PATH-HHT was an NHLBI-funded, randomized, placebo-controlled clinical trial conducted at 13 centers in the US to determine the safety and efficacy of pomalidomide for bleeding in HHT. Pomalidomide was supplied by Celgene and Bristol Myers Squibb. Patients were randomized in a 2:1 ratio to receive pomalidomide 4 mg daily or matching placebo for 6 months. Dose reductions were allowed for toxicity. The primary endpoint was the change in the Epistaxis Severity Score (ESS), a well-validated bleeding score in HHT, from baseline (randomization) to the end of the six-month treatment period, analyzed using a mixed model for repeated measures with adjustment for baseline value, center, treatment, visit, and treatment by visit interaction. Key secondary endpoints included 1) change in the average daily self-reported epistaxis duration from the four weeks preceding the baseline visit to weeks 20-24 of treatment, 2) amount of parenteral iron infused or blood transfused, and 3) change in QOL measurements, including an HHT-specific QOL score. Results PATH-HHT opened in November 2019 and was closed to enrollment by the NHLBI in June 2023 after a planned 75% interim analysis met a prespecified threshold for efficacy. A total of 144 patients were randomized and treated (95 pomalidomide, 49 placebo). Early study discontinuation was 25% in pomalidomide: 14% AE, 11% withdrawn, 1 unrelated death, compared with placebo (4% withdrawn). Across groups, 8% were terminated after 12 weeks for early study closure. Participants included 48% females, 11% non-white race; mean (± SD) age was 58.8±12.2 years. The mean ESS at baseline was 5.0±1.5 (4.9 pomalidomide, 5.2 placebo), consistent with moderate to severe epistaxis. At 24 weeks, the ESS in patients treated with pomalidomide decreased by a mean [95% CI] of -1.84 [-2.24, -1.44] and in the placebo group decreased by -0.89 [-1.39, -0.39] (mean difference -0.95 [-1.58, -0.32], p = 0.003) (Figure, Panel A). Difference between groups was apparent by 12 weeks (mean difference -0.52, 95% CI [-1.04, -0.01], p = 0.045). The HHT-specific QOL score, which ranges from 0 to 16 with higher scores indicating more limitations, also decreased more in the pomalidomide (mean -2.6, 95% CI [-3.3, -1.9]) vs the placebo group at 24 weeks (mean -1.2, 95% CI [-2.1, -0.3], p = 0.015) (Figure, Panel B). Adverse events that occurred more in the pomalidomide group included mild to moderate neutropenia (45% vs. 10%), constipation/diarrhea (60% vs. 37%), and rash (36% vs. 10%). Venous thrombosis occurred in 2% of patients in each group. Conclusion PATH-HHT is the largest and the first adequately powered, randomized trial of systemic therapy in HHT. The study demonstrated a significant and highly clinically relevant reduction in epistaxis in pomalidomide-treated patients as well as an improvement in the HHT-specific QOL score. Pomalidomide may offer a novel approach to management of HHT. Since plasma was collected from patients in this study before and at the end of treatment, additional studies may identify biomarkers predicting pomalidomide responses.

ImportanceYoung women with breast cancer who have germline pathogenic variants in BRCA1 or BRCA2 face unique challenges regarding fertility. Previous studies demonstrating the feasibility and safety of pregnancy in breast cancer survivors included limited data regarding BRCA carriers.ObjectiveTo investigate cumulative incidence of pregnancy and disease-free survival in young women who are BRCA carriers.Design, Setting, and ParticipantsInternational, multicenter, hospital-based, retrospective cohort study conducted at 78 participating centers worldwide. The study included female participants diagnosed with invasive breast cancer at age 40 years or younger between January 2000 and December 2020 carrying germline pathogenic variants in BRCA1 and/or BRCA2. Last delivery was October 7, 2022; last follow-up was February 20, 2023.ExposurePregnancy after breast cancer.Main Outcomes and MeasuresPrimary end points were cumulative incidence of pregnancy after breast cancer and disease-free survival. Secondary end points were breast cancer–specific survival, overall survival, pregnancy, and fetal and obstetric outcomes.ResultsOf 4732 BRCA carriers included, 659 had at least 1 pregnancy after breast cancer and 4073 did not. Median age at diagnosis in the overall cohort was 35 years (IQR, 31-38 years). Cumulative incidence of pregnancy at 10 years was 22% (95% CI, 21%-24%), with a median time from breast cancer diagnosis to conception of 3.5 years (IQR, 2.2-5.3 years). Among the 659 patients who had a pregnancy, 45 (6.9%) and 63 (9.7%) had an induced abortion or a miscarriage, respectively. Of the 517 patients (79.7%) with a completed pregnancy, 406 (91.0%) delivered at term (≥37 weeks) and 54 (10.4%) had twins. Among the 470 infants born with known information on pregnancy complications, 4 (0.9%) had documented congenital anomalies. Median follow-up was 7.8 years (IQR, 4.5-12.6 years). No significant difference in disease-free survival was observed between patients with or without a pregnancy after breast cancer (adjusted hazard ratio, 0.99; 95% CI, 0.81-1.20). Patients who had a pregnancy had significantly better breast cancer–specific survival and overall survival.Conclusions and RelevanceIn this global study, 1 in 5 young BRCA carriers conceived within 10 years after breast cancer diagnosis. Pregnancy following breast cancer in BRCA carriers was not associated with decreased disease-free survival.Trial RegistrationClinicalTrials.gov Identifier: NCT03673306
