2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure
No full textAim: The “2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure” replaces the “2013 ACCF/AHA Guideline for the Management of Heart Failure” and the “2017 ACC/AHA/HFSA Focused Update of the 2013 ACCF/AHA Guideline for the Management of Heart Failure.” The 2022 guideline is intended to provide patient-centric recommendations for clinicians to prevent, diagnose, and manage patients with heart failure. Methods: A comprehensive literature search was conducted from May 2020 to December 2020, encompassing studies, reviews, and other evidence conducted on human subjects that were published in English from MEDLINE (PubMed), EMBASE, the Cochrane Collaboration, the Agency for Healthcare Research and Quality, and other relevant databases. Additional relevant clinical trials and research studies, published through September 2021, were also considered. This guideline was harmonized with other American Heart Association/American College of Cardiology guidelines published through December 2021. Structure: Heart failure remains a leading cause of morbidity and mortality globally. The 2022 heart failure guideline provides recommendations based on contemporary evidence for the treatment of these patients. The recommendations present an evidence-based approach to managing patients with heart failure, with the intent to improve quality of care and align with patients’ interests. Many recommendations from the earlier heart failure guidelines have been updated with new evidence, and new recommendations have been created when supported by published data. Value statements are provided for certain treatments with high-quality published economic analyses
Antibiotic Optimization in the Intensive Care Unit
No full textEffective antimicrobial therapy remains paramount to successful treatment of patients with critical illness, such as pneumonia and sepsis. Unfortunately, critically ill patients often exhibit altered pharmacokinetics and pharmacodynamics (PK/PD) that make this endeavor challenging. Particularly in sepsis, alterations in volume of distribution (Vd) and protein binding lead to unpredictable effects on serum levels of various antimicrobials. Additionally, metabolic pathways and excretion may be significantly impacted due to end-organ failure. These dynamic factors may increase the likelihood of deleterious effects such as treatment failure or toxicity. Meeting these challenging scenarios has led to various strategies meant to improve clinical cure without untoward consequences. Vancomycin and β-lactam antimicrobials are frequently utilized and have been the focus of dose optimization strategies including extended infusion (EI) or continuous infusion (CI). Available data suggests that administration of vancomycin by CI may reduce the risk of nephrotoxicity without increasing the risk of treatment failure, although retrospective data are largely utilized in supporting this method. Other efforts to optimize vancomycin have focused on transitioning from trough-based therapeutic drug monitoring (TDM) to area-under-the-curve: minimum inhibitory concentration (AUC:MIC) ratios. Despite the creation of more user-friendly methods of calculation and data suggesting reduced rates of nephrotoxicity, widespread implementation is limited, in part due to clinician comfort. Use of β-lactams in patients with sepsis is similarly problematic due to observational data demonstrating fluctuations in serum levels in the setting of critical illness. Implementing TDM of agents such as piperacillin-tazobactam, cefepime, and meropenem has been suggested as a method of improving time above MIC (T \u3eMIC). This practice is limited by the lack of access to commercial assays and the failure of rigorous studies to demonstrate improved treatment success. Clinicians should be aware of these challenges and should refine their dosing strategies based on individualized patient factors to reduce treatment failure
Cardiovascular physiology and pathophysiology in Down syndrome
No full textDown syndrome (Ds) is the most common chromosomal cause of intellectual disability that results from triplication of chromosome 21 genes. Individuals with Ds demonstrate cognitive deficits in addition to comorbidities including cardiac defects, pulmonary arterial hypertension (PAH), low blood pressure (BP), and differences in autonomic regulation. Many individuals with Ds are born with heart malformations and some can be surgically corrected. Lower BP at rest and in response to exercise and other stressors are a prevalent feature in Ds. These reduced cardiovascular responses may be due to underlying autonomic dysfunction and have been implicated in lower exercise/work capacity in Ds, which is an important correlate of morbidity, mortality and quality of life. Exercise therapy can be beneficial to normalize autonomic function and may help prevent the development of co-morbidities in Ds. We will review cardiovascular physiology and pathophysiology in individuals with Ds, along with exercise therapy and special considerations for these individuals
The effects of feedback valance and progress monitoring on goal striving
No full textThe current paper explores how people’s goal strivings are influenced by feedback (positively valenced vs. negatively valenced), progress monitoring (remaining vs. accumulated) and goal specificity (vague vs. specific). Two laboratory-based experiments were performed. Experiment 1 reveals that, after receiving positively valenced feedback, participants who focus on accumulated progress show larger boosts in persistence than participants who focus on remaining progress. In contrast, after receiving negatively valenced feedback, participants who focus on remaining progress show larger boosts in persistence than participants who focus on accumulated progress. Experiment 2 extends the scope of the paper from understanding the effects of progress monitoring on goal striving to the effects goal specificity on goal striving. Experiment 2 shows that after receiving negatively valenced feedback, participants asked to consider specific goals (and so likely focus on remaining progress) show more persistence than participants asked to consider vague goals (and so likely focus on accumulated progress). These findings have important implications for motivation theory and applied practice
Interventions for the prevention of adrenal crisis in adults with primary adrenal insufficiency: a systematic review
No full textObjective: The incidence of adrenal crisis (AC) remains high, particularly for people with primary adrenal insufficiency, despite the introduction of behavioural interventions. The present study aimed to identify and evaluate available evidence of interventions aiming to prevent AC in primary adrenal insufficiency. Design: This study is a systematic review of the literature and theoretical mapping. Methods: MEDLINE, MEDLINE in Process, EMBASE, ERIC, Cochrane CENTRAL, CINAHL, PsycINFO, the Health Management Information Consortium and trial registries were searched from inception to November 2021. Three reviewers independently selected studies and extracted data. Two reviewers appraised the studies for the risk of bias. Results: Seven observational or mixed methods studies were identified where interventions were designed to prevent AC in adrenal insufficiency. Patient education was the focus of all interventions and utilised the same two behaviour change techniques, \u27instruction on how to perform a behaviour\u27 and \u27pharmacological support\u27. Barrier and facilitator themes aiding or hindering the intervention included knowledge, behaviour, emotions, skills, social influences and environmental context and resources. Most studies did not measure effectiveness, and assessment of knowledge varied across studies. The study quality was moderate. Conclusion: This is an emerging field with limited studies available. Further research is required in relation to the development and assessment of different behaviour change interventions to prevent AC
A Crossover Randomized Controlled Trial of Priming Interventions to Increase Hand Hygiene at Ward Entrances
No full textBackground: Research conducted in the United States suggests that two primes (citrus smells and pictures of a person\u27s eyes) can increase hand gel dispenser use on the day they are introduced in hospital. The current study, conducted at a hospital in the United Kingdom, evaluated the effectiveness of these primes, both in isolation and in combination, at the entry way to four separate wards, over a longer duration than the previous work. Methods: A crossover randomized controlled trial was conducted. Four wards were allocated for 6 weeks of observation to each of four conditions, including “control,” “olfactory,” “visual,” or “both” (i.e., “olfactory” and “visual” combined). It was hypothesized that hand hygiene compliance would be greater in all priming conditions relative to the control condition. The primary outcome was whether people used the gel dispenser when they entered the wards. After the trial, a follow up survey of staff at the same hospital assessed the barriers to, and facilitators of, hand hygiene compliance. The trial data were analyzed using regression techniques and the survey data were analyzed using descriptive statistics. Results: The total number of individuals observed in the trial was 9,811 (female = 61%), with similar numbers across conditions, including “control” N = 2,582, “olfactory” N = 2,700, “visual” N = 2,488, and “both” N = 2,141. None of the priming conditions consistently increased hand hygiene. The lowest percentage compliance was observed in the “both” condition (7.8%), and the highest was observed in the “visual” condition (12.7%). The survey was completed by 97 staff (female = 81%). “Environmental resources” and “social influences” were the greatest barriers to staff cleaning their hands. Conclusions: Taken together, the current findings suggest that the olfactory and visual priming interventions investigated do not influence hand hygiene consistently. To increase the likelihood of such interventions succeeding, future research should focus on prospectively determined mechanisms of action
Cost-effectiveness of pegfilgrastim versus filgrastim for prevention of chemotherapy-induced febrile neutropenia in patients with lymphoma: a systematic review
No full textBackground: Febrile neutropenia (FN) is a prevalent and potentially life-threatening complication in patients with lymphoma receiving myelosuppressive chemotherapy. Pegfilgrastim is more effective than filgrastim as prophylaxis for FN. However, its usage has been limited because of its higher cost. Pegfilgrastim’s value for money remains unclear. Objective: To systematically review the cost-effectiveness of pegfilgrastim compared to filgrastim as a primary or secondary prophylaxis for chemotherapy-induced FN among patients with lymphoma. Methods: A systematic literature search was conducted in PubMed, EMBASE, Cochrane Library databases, and Google Scholar. The most widely used economic evaluations (cost-effectiveness analysis, cost-utility analysis and cost-benefit analysis) were included in the review. Data extraction was guided by the Consolidated Health Economic Evaluation Reporting Standards checklist, and the quality of reviewed articles was assessed using the Joanna Briggs Institute (JBI) checklist. Cost-effectiveness data were rigorously summarized and synthesized narratively. Costs were adjusted to US 2199 to US 44,358 per FN averted, and US 7251 per life-years gained. The most influential parameters were medication and hospitalization costs, the relative risk of FN, and assumptions of mortality benefit. Conclusions: Most studies showed that pegfilgrastim is cost-effective compared to filgrastim as primary and secondary prophylaxis for chemotherapy-induced FN among patients with lymphoma at a cost-effectiveness threshold of US$ 50,000 per QALY gained. The findings could assist clinicians and healthcare decision-makers to make informed decisions regarding resource allocation for the management of chemotherapy-induced FN in settings similar to those studied
Applying Behavioural Insights to HIV Prevention and Management: a Scoping Review
No full textPurpose of Review: This scoping review summarises the literature on HIV prevention and management interventions utilizing behavioural economic principles encapsulated in the MINDSPACE framework. Recent Findings: MINDSPACE is an acronym developed by the UK’s behavioural insights team to summarise nine key influences on human behaviour: Messenger, Incentives, Norms, Default, Salience, Priming, Affect, Commitment, and Ego. These effects have been used in various settings to design interventions that encourage positive behaviours. Currently, over 200 institutionalised behavioural insight teams exist internationally, which may draw upon the MINDSPACE framework to inform policy and improve public services. To date, it is not clear how behavioural insights have been applied to HIV prevention and management interventions. Summary: After screening 899 studies for eligibility, 124 were included in the final review. We identified examples of interventions that utilised all the MINDSPACE effects in a variety of settings and among various populations. Studies from high-income countries were most common (n = 54) and incentives were the most frequently applied effect (n = 100). The MINDSPACE framework is a useful tool to consider how behavioural science principles can be applied in future HIV prevention and management interventions. Creating nudges to enhance the design of HIV prevention and management interventions can help people make better choices as we strive to end the HIV/AIDS pandemic by 2030
Key informant perspectives about telephonic comprehensive medication review services in the United States
No full textBackground: Comprehensive medication reviews (CMRs) are provided by providers such as pharmacists to eligible beneficiaries. Although CMRs have been shown to provide value to patients, little is known about the service uniformity, quality, and content of CMRs. Objective: This study aimed to characterize the current state of CMR services from diverse stakeholder perspectives and describe variation in responses to content and delivery of telephonic CMR services. Methods: Semistructured interviews were conducted with 10 key informants. The interview guide contained 6 key questions with additional probing questions. Transcripts were analyzed using the inductive saturation model and phenomenological approach to code emergent themes, which were iteratively refined until saturation was achieved. Results: Key informants included CMR payers (n = 3), providers (n = 5), and standards-setting organizations (n = 2). Ten themes about CMRs emerged from qualitative analysis: (1) definition, (2) organizational goals, (3) content, (4) eligibility, (5) frequency, (6) acceptance and completion, (7) process and personnel, (8) quality assurance, (9) preparation, and (10) future directions. CMR content descriptions were consistent across perspectives. Key informants described scenarios appropriate for expanded CMR eligibility criteria, although none were consistently reported. Providers emphasized patient CMR acceptance rates whereas payers and standard-setting organizations emphasized completion rates. Completion rates and adherence to Centers for Medicare and Medicaid Services standards were characterized as core organizational goals (n = 8), whereas patient satisfaction was less frequently identified (n = 4). A lack of incentive for CMR providers to follow-up with patients was a barrier to expanded services. Overall, key informants were dissatisfied with the CMR completion rate measure and would prefer measures focused on service quality and outcomes. Conclusions: CMR services largely met perceived guidelines, with variation in value-added services. Key informants desired adoption of an actionable measure that is focused on quality rather than completion rate. To inform a quality measure, future research should analyze completed CMRs to determine the extent of variation in content and delivery
Impact of Stress Ulcer Prophylaxis Discontinuation Guidance in Mechanically Ventilated, Critically Ill Patients: A Pre-Post Cohort Study
No full textPurpose: Recent data highlight unclear efficacy and potential negative sequelae of stress ulcer prophylaxis (SUP) in the intensive care unit (ICU). Minimizing SUP exposure has pertinent clinical and other implications. This study assessed medication use and clinical outcomes before and after implementation of a practice guideline promoting early discontinuation of SUP in mechanically ventilated ICU patients. Methods: Retrospective, single-center, pre-post cohort study within a medical ICU at a large, academic medical center. Adult patients requiring mechanical ventilation and receiving SUP via a histamine-2 receptor antagonist (H2RA) or proton pump inhibitor (PPI) were eligible for inclusion. The clinical practice guideline was implemented on January 1, 2020. The impact of implementation was assessed via percent of patient-days with inappropriate SUP. Incidence of clinically important GI bleed was the primary safety outcome. Results: A total of 137 pre-guideline and 112 post-guideline patients were included. Comorbidity burden was similar between groups. A higher prevalence of baseline vasopressor receipt (39% vs 67%, P \u3c.01) and acute kidney injury (56% vs 69%, P =.04) was observed in post-guideline patients. Post-guideline patients experienced a significantly lower percentage of patient-days of inappropriate SUP (25% vs 50%, P \u3c.01) as well as higher rates of SUP discontinuation before extubation (71% vs 12%, P \u3c.01) and during ICU stay (93% vs 50%, P \u3c.01). Post-guideline patients observed a significantly lower incidence of SUP at hospital discharge (4% vs 35%, P \u3c.01). No differences in bleeding outcomes were observed, though post-guideline patients experienced longer durations of mechanical ventilation, ICU stay, and hospital stay. Conclusions: Implementation of an early SUP discontinuation guideline was associated with significant improvements in SUP prescribing practices. Baseline differences between groups likely explain observed differences in clinical outcomes
