Clarke, Karen; Adler, Nicole; Agrawal, Deepak; Bhakta, Dimpal; Sata, Suchita Shah; Singh, Sarguni; Gupta, Arjun; Pahwa, Amit; Pherson, Emily; Sun, Alexander; Volpicelli, Frank; Cho, Hyung J
Proton pump inhibitors are widely used throughout the world for the treatment of gastrointestinal disorders that are related to acid secretion, such as peptic ulcer disease and dyspepsia. Another common indication for proton pump inhibitors is stress ulcer prophylaxis. Proton pump inhibitors have proven efficacy for the treatment of acid-related gastrointestinal disorders, but there is concern that their use may be associated with the development of significant complications, such as fractures, Clostridium difficile infection, acute kidney injury, chronic kidney disease, and hypomagnesemia. Proton pump inhibitors are overused in the hospital setting, both for stress ulcer prophylaxis and gastrointestinal bleeding, and then they are often inappropriately continued after discharge from the hospital. This narrative review article outlines the evidence surrounding appropriate proton pump inhibitor use for stress ulcer prophylaxis and peptic ulcer bleeding.

OBJECTIVES/OBJECTIVE:Predictive studies play important roles in the development of models informing care for patients with COVID-19. Our concern is that studies producing ill-performing models may lead to inappropriate clinical decision-making. Thus, our objective is to summarise and characterise performance of prognostic models for COVID-19 on external data. METHODS:We performed a validation of parsimonious prognostic models for patients with COVID-19 from a literature search for published and preprint articles. Ten models meeting inclusion criteria were either (a) externally validated with our data against the model variables and weights or (b) rebuilt using original features if no weights were provided. Nine studies had internally or externally validated models on cohorts of between 18 and 320 inpatients with COVID-19. One model used cross-validation. Our external validation cohort consisted of 4444 patients with COVID-19 hospitalised between 1 March and 27 May 2020. RESULTS:Most models failed validation when applied to our institution's data. Included studies reported an average validation area under the receiver-operator curve (AUROC) of 0.828. Models applied with reported features averaged an AUROC of 0.66 when validated on our data. Models rebuilt with the same features averaged an AUROC of 0.755 when validated on our data. In both cases, models did not validate against their studies' reported AUROC values. DISCUSSION/CONCLUSIONS:Published and preprint prognostic models for patients infected with COVID-19 performed substantially worse when applied to external data. Further inquiry is required to elucidate mechanisms underlying performance deviations. CONCLUSIONS:Clinicians should employ caution when applying models for clinical prediction without careful validation on local data.

Reducing Overuse of Proton Pump Inhibitors for Stress Ulcer Prophylaxis and Nonvariceal Gastrointestinal Bleeding in the Hospital: A Narrative Review and Implementation Guide

Clarke, Karen; Adler, Nicole; Agrawal, Deepak; Bhakta, Dimpal; Sata, Suchita Shah; Singh, Sarguni; Gupta, Arjun; Pahwa, Amit; Pherson, Emily; Sun, Alexander; Volpicelli, Frank; Sreenivasan, Aditya; Cho, Hyung J
Proton pump inhibitors (PPIs) are among the most commonly used medications in the world; however, these drugs carry the risk of patient harm, including acute and chronic kidney disease, Clostridium difficile infection, hypomagnesemia, and fractures. In the hospital setting, PPIs are overused for stress ulcer prophylaxis and gastrointestinal bleeding, and PPI use often continues after discharge. Numerous multifaceted interventions have demonstrated safe and effective reduction of PPI use in the inpatient setting. This narrative review and the resulting implementation guide summarize published interventions to reduce inappropriate PPI use and provide a strategy for quality improvement teams.

Megakaryocytes and platelet-fibrin thrombi characterize multi-organ thrombosis at autopsy in COVID-19: A case series

Rapkiewicz, Amy V; Mai, Xingchen; Carsons, Steven E; Pittaluga, Stefania; Kleiner, David E; Berger, Jeffrey S; Thomas, Sarun; Adler, Nicole M; Charytan, David M; Gasmi, Billel; Hochman, Judith S; Reynolds, Harmony R
Background/UNASSIGNED:There is increasing recognition of a prothrombotic state in COVID-19. Post-mortem examination can provide important mechanistic insights. Methods/UNASSIGNED:We present a COVID-19 autopsy series including findings in lungs, heart, kidneys, liver, and bone, from a New York academic medical center. Findings/UNASSIGNED: = 2). Platelet-rich peri‑tubular fibrin microthrombi were a prominent renal feature. Acute tubular necrosis, and red blood cell and granular casts were seen in multiple cases. Significant glomerular pathology was notably absent. Numerous platelet-fibrin microthrombi were identified in hepatic sinusoids. All lungs exhibited diffuse alveolar damage (DAD) with a spectrum of exudative and proliferative phases including hyaline membranes, and pneumocyte hyperplasia, with viral inclusions in epithelial cells and macrophages. Three cases had superimposed acute bronchopneumonia, focally necrotizing. Interpretation/UNASSIGNED:In this series of seven COVID-19 autopsies, thrombosis was a prominent feature in multiple organs, in some cases despite full anticoagulation and regardless of timing of the disease course, suggesting that thrombosis plays a role very early in the disease process. The finding of megakaryocytes and platelet-rich thrombi in the lungs, heart and kidneys suggests a role in thrombosis. Funding/UNASSIGNED:None.

Bending the cost curve: time series analysis of a value transformation programme at an academic medical centre

Chatfield, Steven C; Volpicelli, Frank M; Adler, Nicole M; Kim, Kunhee Lucy; Jones, Simon A; Francois, Fritz; Shah, Paresh C; Press, Robert A; Horwitz, Leora I
BACKGROUND:Reducing costs while increasing or maintaining quality is crucial to delivering high value care. OBJECTIVE:To assess the impact of a hospital value-based management programme on cost and quality. DESIGN/METHODS:Time series analysis of non-psychiatric, non-rehabilitation, non-newborn patients discharged between 1 September 2011 and 31 December 2017 from a US urban, academic medical centre. INTERVENTION/METHODS:NYU Langone Health instituted an institution-wide programme in April 2014 to increase value of healthcare, defined as health outcomes achieved per dollar spent. Key features included joint clinical and operational leadership; granular and transparent cost accounting; dedicated project support staff; information technology support; and a departmental shared savings programme. MEASUREMENTS/METHODS:Change in variable direct costs; secondary outcomes included changes in length of stay, readmission and in-hospital mortality. RESULTS:The programme chartered 74 projects targeting opportunities in supply chain management (eg, surgical trays), operational efficiency (eg, discharge optimisation), care of outlier patients (eg, those at end of life) and resource utilisation (eg, blood management). The study cohort included 160 434 hospitalisations. Adjusted variable costs decreased 7.7% over the study period. Admissions with medical diagnosis related groups (DRG) declined an average 0.20% per month relative to baseline. Admissions with surgical DRGs had an early increase in costs of 2.7% followed by 0.37% decrease in costs per month. Mean expense per hospitalisation improved from 13% above median for teaching hospitals to 2% above median. Length of stay decreased by 0.25% per month relative to prior trends (95% CI -0.34 to 0.17): approximately half a day by the end of the study period. There were no significant changes in 30-day same-hospital readmission or in-hospital mortality. Estimated institutional savings after intervention costs were approximately $53.9 million. LIMITATIONS/CONCLUSIONS:Observational analysis. CONCLUSION/CONCLUSIONS:A systematic programme to increase healthcare value by lowering the cost of care without compromising quality is achievable and sustainable over several years.

Promoting High-Value Practice by Reducing Unnecessary Transfusions With a Patient Blood Management Program

Sadana, Divyajot; Pratzer, Ariella; Scher, Lauren J; Saag, Harry S; Adler, Nicole; Volpicelli, Frank M; Auron, Moises; Frank, Steven M
Although blood transfusion is a lifesaving therapy for some patients, transfusion has been named 1 of the top 5 overused procedures in US hospitals. As unnecessary transfusions only increase risk and cost without providing benefit, improving transfusion practice is an effective way of promoting high-value care. Most high-quality clinical trials supporting a restrictive transfusion strategy have been published in the past 5 to 10 years, so the value of a successful patient blood management program has only recently been recognized. We review the most recent transfusion practice guidelines and the evidence supporting these guidelines. We also discuss several medical societies' Choosing Wisely campaigns to reduce or eliminate overuse of transfusions. A blueprint is presented for developing a patient blood management program, which includes discussion of specific methods for optimizing transfusion practice.

Reducing liberal red blood cell transfusions at an academic medical center

Saag, Harry S; Lajam, Claudette M; Jones, Simon; Lakomkin, Nikita; Bosco, Joseph A 3rd; Wallack, Rebecca; Frangos, Spiros G; Sinha, Prashant; Adler, Nicole; Ursomanno, Patti; Horwitz, Leora I; Volpicelli, Frank M
BACKGROUND: Educational and computerized interventions have been shown to reduce red blood cell (RBC) transfusion rates, yet controversy remains surrounding the optimal strategy needed to achieve sustained reductions in liberal transfusions. STUDY DESIGN AND METHODS: The purpose of this study was to assess the impact of clinician decision support (CDS) along with targeted education on liberal RBC utilization to four high-utilizing service lines compared with no education to control service lines across an academic medical center. Clinical data along with associated hemoglobin levels at the time of all transfusion orders between April 2014 and December 2015 were obtained via retrospective chart review. The primary outcome was the change in the rate of liberal RBC transfusion orders (defined as any RBC transfusion when the hemoglobin level is >7.0 g/dL). Secondary outcomes included the annual projected reduction in the number of transfusions and the associated decrease in cost due to these changes as well as length of stay (LOS) and death index. These measures were compared between the 12 months prior to the initiative and the 9-month postintervention period. RESULTS: Liberal RBC utilization decreased from 13.4 to 10.0 units per 100 patient discharges (p = 0.002) across the institution, resulting in a projected 12-month savings of $720,360. The mean LOS and the death index did not differ significantly in the postintervention period. CONCLUSION: Targeted education combined with the incorporation of CDS at the time of order entry resulted in significant reductions in the incidence of liberal RBC utilization without adversely impacting inpatient care, whereas control service lines exposed only to CDS had no change in transfusion habits.

Treatment of Leptomeningeal Carcinomatosis in a Patient With Metastatic Cholangiocarcinoma

Jacobs, Ramon E A; McNeill, Katharine; Volpicelli, Frank M; Warltier, Karin; Iturrate, Eduardo; Okamura, Charles; Adler, Nicole; Smith, Joshua; Sigmund, Alana; Mednick, Aron; Wertheimer, Benjamin; Hochman, Katherine
A 49-year-old woman with cholangiocarcinoma metastatic to the lungs presented with new-onset unrelenting headaches. A lumbar puncture revealed malignant cells consistent with leptomeningeal metastasis from her cholangiocarcinoma. Magnetic resonance imaging (MRI) of the brain revealed leptomeningeal enhancement. An intrathecal (IT) catheter was placed and IT chemotherapy was initiated with methotrexate. Her case is notable for the rarity of cholangiocarcinoma spread to the leptomeninges, the use of IT chemotherapy with cytologic and potentially symptomatic response, and a possible survival benefit in comparison to previously reported cases of leptomeningeal carcinomatosis secondary to cholangiocarcinoma.
