Causes and outcomes of non-chemotherapy induced neutropenic fever in hospitalized adults: An observational study.

Neutropenic fever in adults undergoing chemotherapy for cancer treatment is a medical emergency and has been the focus of numerous studies. However, there is a paucity of data about non-chemotherapy induced neutropenic fever (non-CINF). We retrospectively reviewed 383 adults with neutropenic fever hospitalized at one academic medical center between October 2015 and September 2020 to characterize the frequency, causes, and outcomes of non-CINF. Twenty-six percent of cases of neutropenic fever were non-chemotherapy induced. Among these, the major causes of neutropenia were hematologic malignancy, infection, and rheumatologic disease, and the major causes of fever were infections. Patients with non-CINF had a higher 30-day mortality than those with chemotherapy induced neutropenic fever (25% vs 13%, P = .01). Non-CINF constituted > 25% of neutropenic fever events in hospitalized adults and was associated with a high mortality rate.

Development and validation of a risk model for hospital-acquired venous thrombosis: the Medical Inpatients Thrombosis and Hemostasis study.

BACKGROUND: Regulatory organizations recommend assessing hospital-acquired (HA) venous thromboembolism (VTE) risk for medical inpatients. OBJECTIVES: To develop and validate a risk assessment model (RAM) for HA-VTE in medical inpatients using objective and assessable risk factors knowable at admission. METHODS: The development cohort included people admitted to medical services at the University of Vermont Medical Center (Burlington, Vermont) between 2010 and 2019, and the validation cohorts included people admitted to Hennepin County Medical Center (Minneapolis, Minnesota), University of Michigan Medical Center (Ann Arbor, Michigan), and Harris Health Systems (Houston, Texas). Individuals with VTE at admission, aged <18 years, and admitted for <1 midnight were excluded. We used a Bayesian penalized regression technique to select candidate HA-VTE risk factors for final inclusion in the RAM. RESULTS: The development cohort included 60 633 admissions and 227 HA-VTE, and the validation cohorts included 111 269 admissions and 651 HA-VTE. Seven HA-VTE risk factors with t statistics ≥1.5 were included in the RAM: history of VTE, low hemoglobin level, elevated creatinine level, active cancer, hyponatremia, increased red cell distribution width, and malnutrition. The areas under the receiver operating characteristic curve and calibration slope were 0.72 and 1.10, respectively. The areas under the receiver operating characteristic curve and calibration slope were 0.70 and 0.93 at Hennepin County Medical Center, 0.70 and 0.87 at the University of Michigan Medical Center, and 0.71 and 1.00 at Harris Health Systems, respectively. The RAM performed well stratified by age, sex, and race. CONCLUSION: We developed and validated a RAM for HA-VTE in medical inpatients. By quantifying risk, clinicians can determine the potential benefits of measures to reduce HA-VTE.

The 21st Century Cures Act: Inpatient Clinician Perceptions of Changes to Information Sharing at an Academic Medical Center.

Introduction To comply with the Information Blocking Rule in the 21st Century Cures Act, many hospitals began to release inpatient electronic health information such as clinical notes and results to patients immediately, starting in April 2021. We sought to understand the perceptions of hospital-based clinicians regarding the impact of these changes in information sharing on clinicians and patients. Materials and methods We developed and distributed an electronic survey to 122 inpatient attending physicians, resident physicians, and physician assistants within the internal medicine and family medicine departments at an academic medical center. The survey asked clinicians to rate their comfort with information-sharing protocols and describe their perceptions of the impact of immediate information sharing on their documentation habits and patient interactions following the implementation of the Cures Act. Results The survey response rate was 37.7% (46/122). Of the respondents, 56.5% felt comfortable with the note-sharing process, 84.8% reported omitting specific information from their notes to prevent patients from reading it, and 39.1% of clinicians agreed that patients have found clinical notes "more confusing than helpful." Conclusions Immediate sharing of electronic health information has the potential to be a powerful tool for communicating with hospitalized patients. However, our results show many hospital-based clinicians report limited comfort with the note-sharing process and perceive it to be confusing to patients. Efforts are needed to educate clinicians regarding information sharing, understand patient and family perspectives, and develop best practices to enhance communication through electronic notes.

Development of a computable phenotype using electronic health records for venous thromboembolism in medical inpatients: the Medical Inpatient Thrombosis and Hemostasis study.

Background: Accurate and efficient methods to identify venous thromboembolism (VTE) events in hospitalized people are needed to support large-scale studies. Validated computable phenotypes using a specific combination of discrete, searchable elements in electronic health records to identify VTE and distinguish between hospital-acquired (HA)-VTE and present-on-admission (POA)-VTE would greatly facilitate the study of VTE, obviating the need for chart review. Objectives: To develop and validate computable phenotypes for POA- and HA-VTE in adults hospitalized for medical reasons. Methods: The population included admissions to medical services from 2010 to 2019 at an academic medical center. POA-VTE was defined as VTE diagnosed within 24 hours of admission, and HA-VTE as VTE identified more than 24 hours after admission. Using discharge diagnosis codes, present-on-admission flags, imaging procedures, and medication administration records, we iteratively developed computable phenotypes for POA-VTE and HA-VTE. We assessed the performance of the phenotypes using manual chart review and survey methodology. Results: Among 62,468 admissions, 2693 had any VTE diagnosis code. Using survey methodology, 230 records were reviewed to validate the computable phenotypes. Based on the computable phenotypes, the incidence of POA-VTE was 29.4 per 1000 admissions and that of HA-VTE was 3.6 per 1000 admissions. The POA-VTE computable phenotype had positive predictive value and sensitivity of 88.8% (95% CI, 79.8%-94.0%) and 99.1% (95% CI, 94.0%- 99.8%), respectively. Corresponding values for the HA-VTE computable phenotype were 84.2% (95% CI, 60.8%-94.8%) and 72.3% (95% CI, 40.9%-90.8%). Conclusion: We developed computable phenotypes for HA-VTE and POA-VTE with adequate positive predictive value and sensitivity. This phenotype can be used in electronic health record data-based research.

Integrating High-Value Care Concepts into Preclinical Medical Education: A Practical Approach.

Objectives: Although some US medical schools have incorporated high-value care into their preclinical curriculum, there is no standardized approach and major curricular overhaul can be prohibitively onerous. The objectives of this study were to develop a feasible and effective high-value care curriculum, integrate it into an existing pre-clinical course, and assess student and faculty perceptions of the educational value of the curriculum. Methods: Between 2019 and 2021, University of Vermont preclinical medical students participating in the Students & Trainees Advocating for Resource Stewardship (STARS) program collaborated with the faculty director of the preclinical pathophysiology course to identify Choosing Wisely® recommendations relevant to course topics. For each recommendation, STARS students created a case-based, multiple-choice question, answer key and rationale to accompany standard course materials. At each year's course completion, participating students and faculty were invited to complete a survey to assess their perceptions of the curriculum. Results: Seventeen case-based questions were integrated into existing pathophysiology course sessions each year. Over the 3-year period, 420 students and 35 teaching faculty participated in the course, and 171 (40.7%) students and 24 (68.6%) faculty completed the post-course survey. Among student respondents, 80% agreed the curriculum increased their awareness of high-value care, 79% agreed they would be more likely to apply high-value care concepts during their medical career, and 92% agreed it was valuable to discuss Choosing Wisely® recommendations during the second year of medical school. Conclusion: A student-led initiative to incorporate high-value care content within an existing pre-clinical course was well-received by medical students, who reported increased awareness of and intention to apply high-value care principles. This model may offer a feasible and effective approach to high-value care education in the absence of an extensive formal curriculum.

Promoting scholarship in improvement science: A model for academic clinical departments.

Introduction: Clinical departments at academic medical centers strive to deliver clinical care, provide education and training, support faculty development, and promote scholarship. These departments have experienced increasing demands to improve the quality, safety, and value of care delivery. However, many academic departments lack a sufficient number of clinical faculty members with expertise in improvement science to lead initiatives, teach, and generate scholarship. In this article, we describe the structure, activities, and early outcomes of a program within an academic department of medicine to promote scholarly improvement work. Methods: The Department of Medicine at the University of Vermont Medical Center launched a Quality Program with three primary goals: (a) improve care delivery, (b) provide education and training, and (c) promote scholarship in improvement science. The program serves as a resource center for students, trainees and faculty, offering education and training, analytic support, consultation in design and methodology, and project management. It strives to integrate education, research, and care delivery to learn, apply evidence and improve health care. Results: Over the first 3 years of full implementation, the Quality Program supported an average of 123 projects annually, including prospective clinical quality improvement initiatives, retrospective assessment of clinical programs and practices, and curriculum development and evaluation. The projects have yielded a total of 127 scholarly products, defined as peer-reviewed publications and abstracts, posters, and oral presentations at local, regional, and national conferences. Conclusions: The Quality Program may serve as a practical model for promoting care delivery improvement, training, and scholarship in improvement science while advancing the goals of a learning health system at the level of an academic clinical department. Dedicated resources within such departments offer the potential to enhance care delivery while promoting academic success for faculty and trainees in improvement science.

Evaluation of a New Hospital Building's Impact on Clinical Outcomes and Consumer Experience in Medical Inpatients.

Hospitals often seek to improve the effectiveness and experience of care through new building construction. However, the association between the built hospital environment, patient outcomes, and patient experience remains unclear. This retrospective matched cohort study leveraged natural experimental conditions to characterize major clinical outcomes and patient experience in medicine patients admitted to a new hospital building incorporating evidence-based design features compared with controls admitted to legacy buildings. Among patients discharged between June 1, 2019, and March 1, 2020, there were no significant differences in intensive care unit transfer, inpatient mortality, 30-day readmission, 30-day mortality, or length of stay. However, discharge from the new hospital building was associated with a higher percentage of top box scores on the Hospital Consumer Assessment of Healthcare Providers and Systems overall hospital rating item (60% vs 76%, P = 0.02). Further studies are needed to identify specific hospital design features that influence patient experience and clinical outcomes.

The relative risk of bleeding after medical hospitalization: the medical inpatient thrombosis and hemorrhage study.

BACKGROUND: Clinically relevant bleeding risk in discharged medical patients is underestimated and leads to rehospitalization, morbidity, and mortality. Studies assessing this risk are lacking. OBJECTIVE: The aim of this study was to develop and validate a computable phenotype for clinically relevant bleeding using electronic health record (EHR) data and quantify the relative and absolute risks of this bleeding after medical hospitalization. METHODS: We conducted an observational cohort study of people receiving their primary care at sites affiliated with an academic medical center in northwest Vermont, United States. We developed a computable phenotype using EHR data (diagnosis codes, procedure codes, laboratory, and transfusion data) and validated it by manual chart review. Cox proportional hazard models with hospitalization modeled as a time-varying covariate were used to estimate clinically relevant bleeding risk. RESULTS: The computable phenotype had a positive predictive value of 80% and a negative predictive value of 99%. The bleeding rate in individuals with no medical hospitalizations in the past 3 months was 2.9 per 1000 person-years versus 98.9 per 1000 person-years in those who were discharged in the past 3 months. This translates into a hazard ratio (95% CI) of clinically relevant bleeding of 22.9 (18.9, 27.7), 13.0 (10.0, 16.9), and 6.8 (4.7, 9.8) over the first, second, and third months after discharge, respectively. CONCLUSION: We developed and validated a computable phenotype for clinically relevant bleeding and determined its relative and absolute risk in the 3 months after medical hospitalization discharge. The high rates of bleeding observed underscore the clinical importance of capturing and further studying bleeding after medical discharge.

Effect of Patient Safety Curriculum for Internal Medicine Residents on a Health Care System.

Background: Healthcare organizations seeking to promote a safety culture depend on engaged clinicians. Academic medical centers include a community of physicians-in-training; however, medical residents and fellows are historically less engaged in patient safety (PS) than are other clinicians. Increased attention has been focused on integrating PS into graduate medical education. Nonetheless, developing curricula that result in real-world system changes is difficult. Objective: To develop an interactive PS curriculum for internal medicine (IM) residents that analyzes real-word PS problems. Methods: A multidisciplinary group developed a five-session, case-based PS curriculum for IM residents in the context of a 3-year, longitudinal quality-improvement, PS, and high-value-care curriculum. The curriculum was facilitated by a PS analyst and incorporated mock root cause analysis (RCA) based on actual resident-reported PS events. Each mock RCA developed an action plan, and outcomes were tracked. Pre- and postcurriculum assessments with participating residents were conducted to evaluate the curriculum. Results: Twenty-eight IM residents completed the curriculum during four iterations from 2017 to 2020. The curriculum identified multiple potential PS risks, led to tangible changes in clinical processes, and enhanced resident confidence in improving systems of care. Conclusions: We describe an active-learning PS curriculum for IM residents that addressed actual resident-reported PS problems. Through RCA, action items were identified and meaningful system changes were made. Leveraging the expertise of local PS experts in the design and delivery of PS curricula may improve the translation of learner recommendations into real system changes and cultivate a positive PS culture.

Venous thrombosis risk during and after medical and surgical hospitalizations: The medical inpatient thrombosis and hemostasis (MITH) study.

BACKGROUND: Thirty to seventy percent of all venous thromboembolism (VTE) events are associated with hospitalization. The absolute and relative risks during and after hospitalization are poorly characterized. OBJECTIVES: Quantify the absolute rate and relative risk of VTE during and up to 3 months after medical and surgical hospitalizations. PATIENTS/METHODS: We conducted an observational cohort study between 2010 and 2016 of patients cared for by the University of Vermont (UVM) Health Network's primary care population. Cox proportional hazard models with hospitalization modeled as a time-varying covariate were used to estimate VTE risk. RESULTS: Over 4.3 years of follow-up, 55 220 hospitalizations (156 per 1000 person-years) and 713 first venous thromboembolism events (2.0 per 1000 person-years) occurred. Among individuals not recently hospitalized, the rate of venous thromboembolism was 1.4 per 1000 person-years and 71.8 per 1000 person-years during hospitalization. During the first, second, and third months after discharge, the rates of venous thromboembolism were 35.1, 11.3, and 5.2 per 1000 person-years, respectively. Relative to those not recently hospitalized, the age- and sex-adjusted HRs of venous thromboembolism were 38.0 (95% CI 28.0, 51.5) during hospitalization, and 18.4 (95% CI 15.0, 22.6), 6.3 (95% CI 4.3, 9.0), and 3.0 (95% CI 1.7, 5.4) during the first, second, and third months after discharge, respectively. Stratified by medical versus surgical services the rates were similar. CONCLUSION: Hospitalization and up to 3 months after discharge were strongly associated with increased venous thromboembolism risk. These data quantify this risk for use in future studies.

An Active-Learning Quality Improvement Curriculum for Faculty in Hospital Medicine.

INTRODUCTION: Despite the growing importance of quality improvement (QI) training in medical education, there is a lack of faculty with expertise in QI at many academic medical centers. In this report, we describe the design, implementation, and evaluation of a QI training program for faculty in hospital medicine at an academic medical center aimed at increasing faculty capacity in QI. METHODS: With input from an initial focus group of hospital medicine faculty, we developed a 12-session, active-learning curriculum incorporating core concepts in QI applied to a real-life QI problem. We used a survey instrument to assess changes in self-reported confidence, the Quality Improvement Knowledge Application Tool-Revised to assess changes in applied knowledge, and a second focus group to obtain qualitative feedback regarding the curriculum. RESULTS: Self-reported confidence in numerous QI skills increased after completion of the curriculum; however, concurrent improvement in applied knowledge was not observed. Qualitatively, participants not only described improved understanding of QI methodology and greater confidence contributing to QI initiatives but also a sense they were not prepared to lead a QI project independently. DISCUSSION: An active-learning faculty training program is feasible with limited resources and was associated with increased faculty confidence in QI skills.

Predictors and Consequences of Inappropriate Thyroid Ultrasound in Hypothyroidism.

Introduction In 2012, the American Board of Internal Medicine Foundation established the Choosing Wisely® initiative, partnering with specialist societies to promote evidence-based care. Under this program, the Endocrine Society recommends against ordering thyroid ultrasounds in individuals with subclinical or overt hypothyroidism and a normal neck exam. We sought to understand the prevalence, predictors, and consequences of thyroid ultrasound performed at our academic medical center that are not in compliance with this recommendation. Methods We conducted a retrospective cohort study of electronic health record data from January 1, 2016 to July 31, 2018. Data were extracted from records of all patients who underwent thyroid ultrasonography. Ultrasounds were considered inappropriate if they were ordered based on hypothyroidism, without other clear indications. Results A total of 2,021 patients underwent thyroid ultrasonography, of which 572 (28.3%) were diagnosed with hypothyroidism. Among the patients with hypothyroidism, 40 were identified as having received an inappropriate ultrasound (7.0%). Of those patients who received inappropriate ultrasounds, 42.5% had subsequent medical encounters, with a mean charge of $851 (standard deviation = $271) per patient. Using a multivariable model, the odds of receiving an inappropriate ultrasound were significantly higher for patients younger than 50 years of age (odds ratio: 2.37, 95% confidence interval: 1.01-5.58). Conclusion Seven percent of thyroid ultrasounds were inappropriately ordered in a cohort with hypothyroidism. Patients aged <50 years were at an increased risk of inappropriate ultrasound. Sequelae of inappropriate ultrasound included further medical encounters and financial burdens. Systems to reduce the inappropriate use of thyroid ultrasound may lessen the consequences of unnecessary medical imaging.

The Impact of a Nursing Strike on Glycemic Control in Hospitalized Patients with Diabetes.

Introduction Hyperglycemia and hypoglycemia have been found to increase morbidity and mortality among hospitalized patients with diabetes. In July of 2018, our academic medical center experienced a 48-hour nursing strike, during which time 600 replacement nurses were employed. This cohort study evaluated the impact of the nursing strike on glycemic control among hospitalized patients with diabetes. Methods Point-of-care fingerstick blood glucose (POC BG) values among hospitalized patients with diabetes were compared between the 48-hour nursing strike period and two 48-hour periods when the nursing strike did not occur. We evaluated the percentage of POC BG values that were hyperglycemic (POC BG 181-250 mg/dL), severely hyperglycemic (POC BG >250 mg/dL), and hypoglycemic (POC BG <70 mg/dL). Additionally, we assessed the proportion of patients who experienced one or more days of hypoglycemia, hyperglycemia, or severe hyperglycemia. Results We found a significant association between the distributions of POC BG test results during the nursing strike; test results more frequently showed hyperglycemia, severe hyperglycemia, or hypoglycemia during the nursing strike than during the control period (p=0.006). There was a significant difference in the days of hypoglycemia, with 7.7% of patients experiencing one or more days of hypoglycemia during the strike period compared with 1.4% of patients during the control period (p=0.03). Conclusion Nursing strikes have been employed as a last resort in contract negotiations with hospitals, but they have the potential to significantly affect patient care and safety. Further studies are needed to evaluate these impacts to prepare for future workforce disruptions.

Partnering With Patients in a Quality Improvement Curriculum for Internal Medicine Residents.

Patient experience is a core component of the Institute for Healthcare Improvement Triple Aim for health care improvement. Although resident physicians must meet quality improvement (QI) competencies prior to graduation, QI training during residency may not adequately prepare residents to improve patient and family experience. We describe an active learning QI curriculum engaging 3 Patient and Family Advisors as partners alongside 15 resident physicians. This partnership proved to be a meaningful experience for both groups, with the development of mutual respect and insight into the contributions that patients and families bring to solving problems in health care quality.

Improving Management of Type 2 Diabetes Mellitus in Hospitalized Adults: A Quality Initiative.

ABSTRACT: The American Diabetes Association recommends scheduled basal and nutritional insulin doses as the preferred treatment for noncritically ill hospitalized patients with type 2 diabetes; however, the adoption of these practices remains suboptimal. We sought to understand current diabetes management practices and improve glycemic control in patients with type 2 diabetes on the Hospital Medicine Services at our academic medical center. We surveyed resident and attending physicians to understand barriers to guideline-based practice. We conducted educational sessions, developed pocket-card decision aids, encouraged discussion on rounds, and provided periodic performance feedback to attending physicians. Results of the barriers survey identified "fear of causing hypoglycemia" as the most common barrier to guideline-based practice. Compared with the preintervention 12-month period, these interventions were associated with doubling of the use of guideline-based insulin therapy regimens, a significant reduction in the rate of severe hyperglycemia days, and a nonsignificant reduction in the rate of hypoglycemia days over a 12-month period. These results demonstrate that a simple, low-cost intervention can be associated with an increase in guideline-concordant insulin ordering with improvement in glycemic outcomes for patients with type 2 diabetes.

Patients' Perspectives of Diagnostic Error: A Qualitative Study.

OBJECTIVES: The Institute of Medicine (IOM) defines diagnostic error as the failure to establish an accurate or timely explanation for the patient's health problem(s) or effectively communicate the explanation to the patient. Using this definition, we sought to characterize diagnostic errors experienced by patients and describe patient perspectives on causes, impacts, and prevention strategies. METHODS: We conducted interviews of adults hospitalized at an academic medical center. We used the framework of the IOM definition of diagnostic error to perform thematic analysis of qualitative data. Descriptive statistics were used to summarize quantitative data. RESULTS: Based on the IOM's definition of diagnostic error, 27 of the 69 included patients reported at least one diagnostic error in the past 5 years. The errors were distributed evenly across the following three dimensions of the IOM definition: accuracy, communication, and timeliness. Limited time with doctors, communication, clinical assessment, and clinical management emerged as major themes for causes of diagnostic error and for strategies to reduce diagnostic error. Impacts of errors included emotional distress, adverse health outcomes, and impaired activities of daily living. CONCLUSIONS: This study uses the recent IOM definition of diagnostic error to provide insights into diagnostic error from the patient perspective. We found that diagnostic errors were commonly reported by hospitalized adults and have a profound impact on patients' well-being. Patients' insights regarding potential causes and prevention strategies may help identify opportunities to reduce diagnostic errors.

Risk-assessment models for VTE and bleeding in hospitalized medical patients: an overview of systematic reviews.

Multiple risk-assessment models (RAMs) for venous thromboembolism (VTE) in hospitalized medical patients have been developed. To inform the 2018 American Society of Hematology (ASH) guidelines on VTE, we conducted an overview of systematic reviews to identify and summarize evidence related to RAMs for VTE and bleeding in medical inpatients. We searched Epistemonikos, the Cochrane Database, Medline, and Embase from 2005 through June 2017 and then updated the search in January 2020 to identify systematic reviews that included RAMs for VTE and bleeding in medical inpatients. We conducted study selection, data abstraction and quality assessment (using the Risk of Bias in Systematic Reviews [ROBIS] tool) independently and in duplicate. We described the characteristics of the reviews and their included studies, and compared the identified RAMs using narrative synthesis. Of 15 348 citations, we included 2 systematic reviews, of which 1 had low risk of bias. The reviews included 19 unique studies reporting on 15 RAMs. Seven of the RAMs were derived using individual patient data in which risk factors were included based on their predictive ability in a regression analysis. The other 8 RAMs were empirically developed using consensus approaches, risk factors identified from a literature review, and clinical expertise. The RAMs that have been externally validated include the Caprini, Geneva, IMPROVE, Kucher, and Padua RAMs. The Padua, Geneva, and Kucher RAMs have been evaluated in impact studies that reported an increase in appropriate VTE prophylaxis rates. Our findings informed the ASH guidelines. They also aim to guide health care practitioners in their decision-making processes regarding appropriate individual prophylactic management.

Promoting appropriate utilisation of laboratory tests for inflammation at an academic medical centre.

Erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) are commonly ordered in clinical practice to evaluate for inflammation. CRP is a more sensitive and specific test for detecting acute phase inflammation, and the American Society for Clinical Pathology recommends ordering CRP rather than ESR to detect acute phase inflammation in patients with undiagnosed conditions. We sought to understand CRP and ESR ordering practices and reduce unnecessary use of ESR testing at our academic medical centre. We surveyed physician leaders in clinical areas with high utilisation of ESR testing to understand the drivers of potential overutilisation of these tests. Based on survey responses, we designed an intervention focused on education, clinical decision support within the electronic medical record and quarterly audit and feedback. We evaluated appropriateness of ESR ordering before and after the intervention via structured chart audit. Comparison of monthly rates of ESR tests during the preintervention and postintervention periods was conducted using interrupted time series analysis. Clinical habit and ease of test ordering were identified as key drivers of ESR overuse. Compared with the preintervention period, we observed a 33% reduction in the number of ESR tests per month and a 25% reduction in combined CRP and ESR tests per month during the postintervention period. This reduction corresponded to an annual avoidance of 2633 ESR tests with a corresponding estimated direct cost avoidance of $23 701 annually. Although the rate of ESR testing decreased, there was no significant improvement in the clinical appropriateness of residual ESR test ordering following the intervention. A multifaceted intervention was associated with significant decreases in unnecessary ESR tests and concurrent ESR and CRP tests at our academic medical centre. Despite these reductions, there are continued opportunities to reduce inappropriate ESR testing.
