The Centers for Medicare and Medicaid Services (CMS) Community-Acquired Pneumonia Core Measures Lead to Unnecessary Antibiotic Administration by Emergency Physicians

Objectives: The objectives were to assess emergency physician (EP) understanding of the Centers for Medicare and Medicaid Services (CMS) core measures for community‐acquired pneumonia (CAP) guidelines and to determine their self‐reported effect on antibiotic prescribing patterns. Methods: A convenience sample of EPs from five medical centers in North Carolina was anonymously surveyed via a Web‐based instrument. Participants indicated their level of understanding of the CMS CAP guidelines and the effects on their prescribing patterns for antibiotics. Results: A total of 121 EPs completed the study instrument (81%). All respondents were aware of the CMS CAP guidelines. Of these, 95% (95% confidence interval [CI] = 92% to 98%) correctly understood the time‐based guidelines for antibiotic administration, although 24% (95% CI = 17% to 31%) incorrectly identified the onset of this time period. Nearly all physicians (96%; 95% CI = 93% to 99%) reported institutional commitment to meet these core measures, and 84% (95% CI = 78% to 90%) stated that they had a department‐based CAP protocol. More than half of the respondents (55%; 95% CI = 47% to 70%) reported prescribing antibiotics to patients they did not believe had pneumonia in an effort to comply with the CMS guidelines, and 42% (95% CI = 34% to 50%) of these stated that they did so more than three times per month. Only 40% (95% CI = 32% to 48%) of respondents indicated a belief that the guidelines improve patient care. Of those, this was believed to occur by increasing pneumonia awareness (60%; 95% CI = 52% to 68%) and improving hospital processes when pneumonia is suspected (86%; 95% CI = 80% to 92%). Conclusions: Emergency physicians demonstrate awareness of the current CMS CAP guidelines. Most physicians surveyed reported the presence of institutional protocols to increase compliance. More than half of EPs reported that they feel the guidelines led to unnecessary antibiotic usage for patients who are not suspected to have pneumonia. Only 40% of EPs believe that CAP awareness and expedient care resulting from these guidelines has improved overall pneumonia‐related patient care. Outcome‐based data for non–intensive care unit CAP patients are lacking, and EPs report that they prescribe antibiotics when they may not be necessary to comply with existing guidelines.     

Fecal Incontinence: A Stepwise Approach to Primary Care Management

Fecal incontinence can adversely affect quality of life, leading to embarrassment and social isolation. It occurs more often in older adults and is a common reason for nursing home referrals. Numerous treatments are available, but most patents self-treat and often do not report their symptoms. Advanced practice nurses providing primary care develop a rapport with the patient, allowing him or her to elicit important information about this sensitive subject. Interventions are designed to relieve symptoms and decrease incontinence episodes, ultimately improving quality of life. Management follows a stepwise approach beginning with conservative methods and newer technologies when indicated.     

An Interdisciplinary Code Sepsis Team to Improve Sepsis-Bundle Compliance: A Quality Improvement Project

ProblemSepsis is one of the leading causes of mortality, with more than 700,000 hospitalizations and 200,000 deaths annually. Various tools exist to aid in the early identification and treatment of sepsis, including electronic alert systems, standardized order sets, nurse-initiated protocols (NIPs) and specially trained teams. Despite available guidelines, mortality rates for severe sepsis and septic shock are near 50%.MethodsThe aims of this rapid cycle quality improvement project were to develop and implement an interdisciplinary team to address early implementation of sepsis bundles in the emergency department and to compare sepsis bundle compliance 3 months pre- and 3 months postintervention implementation. The population included all patients above 18 years of age presenting to the emergency department with clinical indications of sepsis, severe sepsis, or septic shock. Data were collected via electronic health records (EHRs), switchboard-paging records, and a billing database.ResultsThe pre-post intervention analysis shows an improvement in time to each bundle element except antibiotics and completion of blood cultures. There were noteworthy changes in meeting bundle compliance in fluid resuscitation volume (χ² = 16.3, P ≤ 0.001): initial lactate collected within 180 min (χ² = 11.3, P ≤ 0.01) and time to second lactate within 360 min (χ² = 27.7, P ≤ 0.001). Mortality rates showed a steady decline from over 12% to 5%. No differences were found in mortality rates related to age or gender.DiscussionInterprofessional teams can use existing knowledge, skills, and tools to improve sepsis-bundle compliance and mortality outcomes in patients with sepsis presenting to the emergency department.     

Review article: A primer for clinical researchers in the emergency department: Part VI. Measuring what matters: Core outcome sets in emergency medicine research

In this series we address important topics for clinicians who participate in research as part of their work in the ED. The overarching goal of clinical research is to improve care and determine which treatment is best. Yet, defining and measuring outcomes – what is ‘best’ – can be one of the most difficult steps in the design of a study, in particular when answers to research questions cannot be captured in simple binary results. This article addresses how to choose outcome measures and highlights the increasingly important concept of core outcome sets.     

Evidence-Based Practice Model to Increase Human Papillomavirus Vaccine Uptake: A Stepwise Approach

ObjectiveTo increase uptake of human papillomavirus (HPV) vaccination by implementing a stepwise evidence-based practice model to offer HPV education along with a strong provider recommendation to parents of youth and adolescents.DesignEvidence-based practice change model.SettingA nurse practitioner–run, primary care walk-in clinic in a rural area of the southeastern United States.ParticipantsParents of youth and adolescents ages 11 to 17 years.Interventions/MeasurementsEducation targeting parental hesitancy and strong recommendations for immunization was administered by health care providers to parents of youth and adolescents eligible for vaccination. The Parent Attitudes About Childhood Vaccine instrument was used to identify the presence and degree of parental hesitancy. Vaccination uptake was measured and compared to the same time period from the previous year.ResultsData collected from the clinic vaccination log during the same 6-week time period in 2018 identified that four youth/adolescents were vaccinated with the HPV vaccine in 2018. During the same 6-week period in 2019 when the practice change was implemented, 38 parents were approached; 24 met eligibility criteria, and all 24 of their youth/adolescents received HPV vaccination.ConclusionImplementation of an evidence-based practice model that includes standing vaccine orders and reminders and recalls may provide an effective way to ensure completion of the HPV vaccine series. Every missed clinical opportunity to vaccinate youth and adolescents against HPV can contribute to lower vaccination rates and increased risk for genital warts and cancers associated with HPV infection.     

Medical Oversight,Educational Core Content,and Proposed Scopes of Practice of Wilderness EMS Providers: A Joint Project Developed by Wilderness EMS Educators,Medical Directors,and Regulators Using a Delphi Approach

Introduction: A disparity exists between the skills needed to manage patients in wilderness EMS environments and the scopes of practice that are traditionally approved by state EMS regulators. In response, the National Association of EMS Physicians Wilderness EMS Committee led a project to define the educational core content supporting scopes of practice of wilderness EMS providers and the conditions when wilderness EMS providers should be required to have medical oversight. Methods: Using a Delphi process, a group of experts in wilderness EMS, representing educators, medical directors, and regulators, developed model educational core content. This core content is a foundation for wilderness EMS provider scopes of practice and builds on both the National EMS Education Standards and the National EMS Scope of Practice Model. These experts also identified the conditions when oversight is needed for wilderness EMS providers. Results: By consensus, this group of experts identified the educational core content for four unique levels of wilderness EMS providers: Wilderness Emergency Medical Responder (WEMR), Wilderness Emergency Medical Technician (WEMT), Wilderness Advanced Emergency Medical Technician (WAEMT), and Wilderness Paramedic (WParamedic). These levels include specialized skills and techniques pertinent to the operational environment. The skills and techniques increase in complexity with more advanced certification levels, and address the unique circumstances of providing care to patients in the wilderness environment. Furthermore, this group identified that providers having a defined duty to act should be functioning with medical oversight. Conclusion: This group of experts defined the educational core content supporting the specific scopes of practice that each certification level of wilderness EMS provider should have when providing patient care in the wilderness setting. Wilderness EMS providers are, indeed, providing health care and should thus function within defined scopes of practice and with physician medical director oversight.     

The Use of Antibiotics to Prevent Serious Sequelae in Children at Risk for Occult Bacteremia: A Meta-analysis

Objective: To determine whether antibiotics prevent serious bacterial infections in children at risk for occult bacteremia.
Methods: Meta-analysis of randomized controlled trials involving children aged 3 months to 36 months without a focus of infection and randomized into 2 treatment groups: 1) no antibiotic vs antibiotic or 2) IM ceftriaxone vs oral antibiotic.
Results: The use of either an oral antibiotic or IM ceftriaxone did trend toward a reduced risk of serious infection, although neither reached statistical significance (OR = 0. 60; 95% CI 0. 10, 3. 49; and OR = 0. 38; 95% CI 0. 12, 1. 17, respectively). It would be necessary to treat 414 patients to prevent 1 serious bacterial infection. When only children with proven occult bacteremia were analyzed, the use of IM ceftriaxone was statistically significant in preventing serious bacterial infections (OR = 0. 25; 95% CI 0. 07, 0. 89).
Conclusions: Clinical judgment should not be replaced by widespread antibiotic use in the approach to a child with fever. If rapid methods to identify children with occult bacteremia, such as polymerase chain reaction, could be improved and become widely available, then antibiotics could be used judiciously on initial visits. Antibiotic use in all children at risk for occult bacteremia implies the treatment of many children unlikely to benefit from such therapy.     

Core Domains for Research on Hospital Inactivity in Acutely Ill Older Adults: A Delphi Consensus Study

ObjectiveTo identify core domains for research studies of physical activity and sedentary behavior during hospitalization for older adults with an acute medical illness.DesignA 4-Round Delphi consensus process. Round 1 invited responses to open-ended questions to generate items for the core domains research. In rounds 2-4, participants were invited to use a Likert scale (1-9) to rate the importance of each core domain for research studies of physical activity and/or sedentary behavior in hospitalized older adults with an acute medical illness.SettingOnline surveys.ParticipantsA total of 49 participants were invited to each round (international researchers, clinicians, policy makers and patients). Response rates across rounds 1-4 were 94%, 88%, 83% and 81%, respectively.InterventionsNone.Main Outcome MeasuresConsensus was defined a priori as ≥70% of respondents rating an item as “critical” (score≥7) and ≤15% of respondents rating an item as “not important” (score≤3).ResultsIn round 2, a total of 9 of 25 core domains reached consensus agreement (physical functioning, general, role functioning, emotional functioning, global quality of life, hospital, psychiatric, cognitive functioning, carer burden). In round 3, an additional 8 reached consensus (adverse events, perceived health status, musculoskeletal, social functioning, vascular, cardiac, mortality, economic). Round 4 participants provided further review and a final rating of all 17 core domains that met consensus in previous rounds. Four core domains were rated as “critically important” to evaluate: physical functioning, social functioning, emotional functioning, and hospital outcomes.ConclusionsThis preliminary work provides international and expert consensus-based core domains for development toward a core-outcome set for research, with the ultimate goal of fostering consistency in outcomes and reporting to accelerate research on effective strategies to address physical activity and/or sedentary behavior in older adults while hospitalized.     

A Novel Approach to Measure Cardiac Output Noninvasively: A Comparison with the Thermodilution Method on Critical Care Patients

OBJECTIVE: To compare the accuracy and reliability of cardiac output (CO) measurement by a Noninvasive Hemodynamic Analyzer (NHA) to the thermodilution cardiac output (COTD) technique in ICU patients of cardiac condition. METHOD: ICU retrospective data collected in a 700-bed university-affiliated regional medical center. The data results from 203 patients who required invasive hemodynamic monitoring for clinical and/or surgical management. RESULTS: The ranges of the two CO measurements were: CO(TD) = 2.06 to 8.8 l/min and CO(NHA) = 2.06 to 8.46 l/min, respectively. The Mean and SD of CO(NHA) = 4.819 l/min +/- 1.053 was near to CO(TD) = 4.902 l/min +/- 1.421. Variance was better for CO(NHA) = 1.110 l/min compared to CO(TD) = 1.421 l/min. Median of CO(NHA) showed 4.813 l/min and CO(TD) = 4.660 l/min. Bias was 0.083 l/min with 95% Confidence Interval (Precision): -0.26 to 0.040, and 95% Limits of Agreement was between -1.661 to 1.827 l/min. CONCLUSIONS: The results of this retrospective study indicate that the CO(NHA) technique may be a promising screening method. Additional studies are needed to explore its diagnostic trending capability. This noninvasive CO technique has been proven to be clinically accurate and may be applicable for telemedicine applications.     

Doppler Vortography: A Color Doppler Approach to Quantification of Intraventricular Blood Flow Vortices

We propose a new approach to quantification of intracardiac vorticity based on conventional color Doppler images —Doppler vortography. Doppler vortography relies on the centrosymmetric properties of the vortices. Such properties induce particular symmetries in the Doppler flow data that can be exploited to describe the vortices quantitatively. For this purpose, a kernel filter was developed to derive a parameter, the blood vortex signature (BVS), that allows detection of the main intracardiac vortices and estimation of their core vorticities. The reliability of Doppler vortography was assessed in mock Doppler fields issued from simulations and in vitro data. Doppler vortography was also tested in patients and compared with vector flow mapping by echocardiography. Strong correlations were obtained between Doppler vortography-derived and ground-truth vorticities (in silico: r² = 0.98, in vitro: r² = 0.86, in vivo: r² = 0.89). Our results indicate that Doppler vortography is a potentially promising echocardiographic tool for quantification of vortex flow in the left ventricle.     

A Novel Approach to Measure Variability in the Anterior Cruciate Ligament Deficient Knee During Walking: The Use of the Approximate Entropy in Orthopaedics

Objective. The evaluation of variability of biological rhythmic activities through measures such as Approximate Entropy (ApEn) has provided important information regarding pathology in disciplines such as cardiology and neurology. This research lead to the “loss of complexity hypothesis” where decreased variability is associated with loss of healthy flexibility rendering the system more rigid and unable to adapt to stresses. ApEn as a measure of variability and complexity, correlates well with pathology while, in some cases, it is predictive of subsequent clinical changes. The study of human gait could benefit from the application of ApEn since it is also a rhythmical oscillation. Our aim was to assess the variability of the ACL deficient knee, since ACL rupture is a common musculoskeletal injury and is accompanied by altered gait patterns and future pathology in the joint. We hypothesized that the ACL deficient knee will exhibit more regular and less variable walking patterns than the contralateral intact knee. Methods. Ten subjects with unilateral deficiency walked on a treadmill at their self-selected speed, 20% faster, and 20% slower, while kinematics were collected (50 Hz) from 80 consecutive strides for each condition. The ApEn of the resulted knee joint flexion-extension time series was calculated. Results. Significantly smaller ApEn values were found in the ACL deficient knee when compared with the contralateral intact (F = 5.57, p = 0.022), for all speeds. ApEn values significantly increased (F = 5.79, p = 0.005) with increases in walking speed. Conclusions. The altered properties of the ACL deficient knee, which exhibits more regular and less variable patterns than the contralateral intact knee, may decrease the adaptability of the system rendering it less able to adjust to perturbations. This could explain the increased future pathology found in the deficient knee. ApEn can be an important tool in assessing pathology and therapeutic interventions in orthopaedics.     

Patient Blood Management: A Patient-Orientated Approach to Blood Replacement with the Goal of Reducing Anemia,Blood Loss and the Need for Blood Transfusion in Elective Surgery

Patient Blood Management (PBM) describes an evidence-based, multidisciplinary therapeutic approach. Its focus is on the treatment of the individual patient and as such comprises transfusion therapy and pharmacotherapy. Furthermore, the applicability of PBM is not limited to the perioperative setting but is applicable also to other therapeutic measures and disciplines where significant blood loss is known to occur and where transfusion of blood products is part of the established treatment. PBM is fundamentally based on 3 pillars: (1) optimization of the (preoperative) erythrocyte volume, (2) reduction of diagnostic, therapeutic, or intraoperative blood loss, and (3) increasing individual tolerance towards anemia and accurate blood transfusion triggers. PBM primarily identifies patients at risk of transfusion and provides a management plan aimed at reducing or eliminating the risk of anemia and the need for allogeneic transfusion, thus reducing the inherent risks, inventory pressures, and the escalating costs associated with transfusion.
