Background: Clinicians typically estimate heart failure (HF) health status using the New York Heart Association (NYHA) class, which is often discordant with patient-reported health status. It is unknown if collecting patient-reported health status improves the accuracy of clinician assessments. Methods: The Patient-Reported Outcomes in Heart Failure Clinic (PRO-HF) trial is a randomized, non-blinded trial evaluating routine Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) collection in HF clinic. Patients with a scheduled visit to Stanford HF clinic between August 30, 2021, and June 30, 2022 were enrolled and randomized to KCCQ-12 assessment or usual care. In this prespecified sub-study, we evaluated whether access to the KCCQ-12 improved the accuracy of clinicians' NYHA assessment or patients' perspectives on their clinician interaction. We surveyed clinicians regarding their patients' NYHA class, quality of life, and symptom frequency. Clinician responses were compared with patients' KCCQ-12 responses. We surveyed patients regarding their clinician interactions. Results: Of the 1,248 enrolled patients, 1,051 (84.2%) attended a visit during the sub-study. KCCQ-12 results were given to the clinicians treating the 528 patients in the KCCQ-12 arm; the 523 patients in the usual care arm completed the KCCQ-12 without the results being shared. The correlation between NYHA class and KCCQ-12 Overall Summary Score was stronger when clinicians had access to the KCCQ-12 (r=-0.73 vs. r=-0.61, p Conclusions: Collecting the KCCQ-12 in HF clinic improved clinicians' accuracy of health status assessment; correspondingly, patients believed their clinicians better understood their symptoms.

Background COVID-19 spurred rapid adoption and expansion of telemedicine. We investigated the factors driving visit modality (telemedicine vs. in-person) for outpatient visits at a large cardiovascular center. Methods We used electronic health record data from March 2020 to February 2021 from four cardiology subspecialties (general cardiology, electrophysiology, heart failure, and interventional cardiology) at a large academic health system in Northern California. There were 21,912 new and return visits with 69% delivered by telemedicine. We used hierarchical logistic regression and cross-validation methods to estimate the variation in visit modality explained by patient, clinician, and visit factors as measured by the mean area under the curve. Results Across all subspecialties, the clinician seen was the strongest predictor of telemedicine usage, while primary visit diagnosis was the next most predictive. In general cardiology, the model based on clinician seen had a mean area under the curve of 0.83, the model based on the primary diagnosis had a mean area under the curve of 0.69, and the model based on all patient characteristics combined had a mean area under the curve of 0.56. There was significant variation in telemedicine use across clinicians within each subspecialty, even for visits with the same primary visit diagnosis. Conclusion Individual clinician practice patterns had the largest influence on visit modality across subspecialties in a large cardiovascular medicine practice, while primary diagnosis was less predictive, and patient characteristics even less so. Cardiovascular clinics should reduce variability in visit modality selection through standardized processes that integrate clinical factors and patient preference.

Background/Problem: Medicare spends more than $900 million annually on cardiac echocardiography. Despite the development of appropriate use criteria for echocardiography to limit inappropriate testing, at least 5% to 20% of studies may remain inappropriate. For simple indications or repeat serial exams, a brief, limited transthoracic echocardiogram (TTE) with minimal views and measurements may answer the diagnostic question. In the current state, there are no guidelines of when to order a comprehensive TTE vs limited TTE or a reminder in our electronic health record system (EPIC) that a TTE has already been done. Few physicians are aware of the possibility of even ordering a limited TTE. Intervention: Patient encounters with repeat comprehensive TTE orders were randomized (in real-time) to the intervention, an electronic reminder or best practice alert (BPA), or control, no reminder. The reminder interrupted the ordering process and notified the ordering provider that a comprehensive TTE result was available within the prior 3 months. The reminder provided a link to the result and offered a limited study order as an alternative. The primary outcome was the number of full versus limited TTEs. Results: Over one year in a tertiary care medical center, 3314 patient encounters were randomized to the intervention (N=1661) with a BPA or control group (N=1653) without a reminder. In the control group, there were 1803 full TTE and 222 limited TTE. In the intervention group, there were 1647 full TTE and 379 limited TTE. Analysis with chi-square testing resulted in a p Conclusion: In this randomized trial, a BPA or interruptive reminder in an EHR reduced repeat comprehensive echo testing. The reduced repeat testing can decrease the cost of care, increase access by decreasing wait times for other patients, and potentially improve the patient experience by avoiding any discomfort associated with testing.

Background: Racial inequities for patients with heart failure (HF) have been widely documented. HF patients who receive cardiology care during a hospital admission have better outcomes. It is unknown whether there are differences in admission to a cardiology or general medicine service by race. This study examined the relationship between race and admission service, and its effect on 30-day readmission and mortality Methods: We performed a retrospective cohort study from September 2008 to November 2017 at a single large urban academic referral center of all patients self-referred to the emergency department and admitted to either the cardiology or general medicine service with a principal diagnosis of HF, who self-identified as white, black, or Latinx. We used multivariable generalized estimating equation models to assess the relationship between race and admission to the cardiology service. We used Cox regression to assess the association between race, admission service, and 30-day readmission and mortality. Results: Among 1967 unique patients (66.7% white, 23.6% black, and 9.7% Latinx), black and Latinx patients had lower rates of admission to the cardiology service than white patients (adjusted rate ratio, 0.91; 95% CI, 0.84–0.98, for black; adjusted rate ratio, 0.83; 95% CI, 0.72–0.97 for Latinx). Female sex and age >75 years were also independently associated with lower rates of admission to the cardiology service. Admission to the cardiology service was independently associated with decreased readmission within 30 days, independent of race. Conclusions: Black and Latinx patients were less likely to be admitted to cardiology for HF care. This inequity may, in part, drive racial inequities in HF outcomes.

Background and Importance Plasmacytomas are monoclonal proliferations of plasma cells that may arise within soft tissue or bone. The skull base is a rare site for plasmacytomas to occur, and few cases have been reported in the literature. When present in the skull base, plasmacytomas may result in cranial neuropathies and often progress to multiple myeloma more rapidly than other intracranial or skeletal plasmacytomas. Clinical Presentation A 69-year-old man presented with a primary complaint of diplopia and an examination consistent with bilateral abducens nerve palsy. No other deficits were noted. Magnetic resonance imaging of the skull base demonstrated a large T1 isointense moderately enhancing lesion centered within the clivus. Endoscopic biopsy of the mass revealed sheets and aggregates of mature monoclonal plasma cells. The patient's initial systemic work-up revealed that this was a solitary lesion, and he was treated with radiation therapy to the skull base with a durable local effect at 18-month follow-up. Unfortunately he progressed to multiple myeloma with peripheral osteolytic lesions but has been stabilized on chemotherapeutics. Conclusion The clivus is an unusual site for intracranial plasmacytomas, and enhancing lesions must be differentiated from chordoma. Characteristic findings on histopathology include an immunoglobulin light-chain restricted clonal proliferation of plasma cells. Treatment is most commonly radiotherapy with surgery reserved for biopsy and palliation. Clinicians should be aware of the increased risk of progression to multiple myeloma in skull base plasmacytomas.

Fibroblast growth factor 23 (FGF23) is a circulating hormone important in phosphate homeostasis. Abnormal serum levels of FGF23 result in systemic pathologies in humans and mice, including renal phosphate wasting diseases and hyperphosphatemia. We sought to uncover the role FGF23 plays in the auditory system due to shared molecular mechanisms and genetic pathways between ear and kidney development, the critical roles multiple FGFs play in auditory development and the known hearing phenotype in mice deficient in klotho (KL), a critical co-factor for FGF23 signaling. Using functional assessments of hearing, we demonstrate that Fgf[Formula: see text] mice are profoundly deaf. Fgf[Formula: see text] mice have moderate hearing loss above 20 kHz, consistent with mixed conductive and sensorineural pathology of both middle and inner ear origin. Histology and high-voltage X-ray computed tomography of Fgf[Formula: see text] mice demonstrate dysplastic bulla and ossicles; Fgf[Formula: see text] mice have near-normal morphology. The cochleae of mutant mice appear nearly normal on gross and microscopic inspection. In wild type mice, FGF23 is ubiquitously expressed throughout the cochlea. Measurements from Fgf[Formula: see text] mice do not match the auditory phenotype of Kl-/- mice, suggesting that loss of FGF23 activity impacts the auditory system via mechanisms at least partially independent of KL. Given the extensive middle ear malformations and the overlap of initiation of FGF23 activity and Eustachian tube development, this work suggests a possible role for FGF23 in otitis media.
