RESUMO

Integrated care pathways (ICPs) are evidence-based decision support tools intended to reduce variation and improve quality of care. Historically, adoption of ICPs has been difficult to measure, as the pathways were outside of the electronic health record (EHR), where care delivery documentation and orders were completed. This Technology Column describes the innovative development and implementation of a diagnosis specific electronic ICP that directly embeds pathway steps into an EHR to facilitate order sets, clinical decision-making, and usage tracking. The pathway was implemented at a seven-hospital academic medical center, and details the technology, team structure, early adoption results, and future directions. As such, the importance of investing and organizing resources to create an eICP (e.g., time, technology, and specialized teams) to provide a user-friendly experience to support early adoption is underscored. Preliminary findings show that the eICP had consistent use in the first year of implementation. This manuscript is intended to serve as a practical guide to build eICPs within behavioral health service areas across institutions.

RESUMO

BACKGROUND: Ethanol use can lead to many health and socio-economic problems. Early identification of risky drinking behaviors helps provide timely clinical and social interventions. Laboratory testing of biomarkers of ethanol use supports the timely identification of individuals with risky drinking behaviors. This review provides an overview of the utility and limitations of ethanol biomarkers in the clinical laboratory. CONTENT: Direct assessment of ethanol in tissues and body fluids has limited utility due to the pharmacokinetics of ethanol. Therefore, the evaluation of ethanol use relies on nonvolatile metabolites of ethanol (direct biomarkers) and measurement of the physiological response to the toxic metabolites of ethanol (indirect biomarkers). Ethanol biomarkers help monitor both chronic and acute ethanol use. The points discussed here include the clinical utility of ethanol biomarkers, testing modalities used for laboratory assessment, the specimens of choice, limitations, and clinical interpretation of results. Finally, we discuss the ethical principles that should guide physicians and laboratorians when using these tests to evaluate alcohol use. SUMMARY: Indirect biomarkers such as carbohydrate-deficient transferrin, mean corpuscular volume, and liver enzymes activities may suggest heavy ethanol use. They lack sensitivity and specificity for timely detection of risky drinking behavior and have limited utility for acute ethanol use. Direct biomarkers such as ethyl glucuronide, ethyl sulfate, and phosphatidylethanol are considered sensitive and specific for detecting acute and chronic ethanol use. However, laboratory assessment and result interpretation lack standardization, limiting clinical utility. Ethical principles including respect for persons, beneficence, and justice should guide testing.

RESUMO

BACKGROUND: Recurrent congestion in cardiac amyloidosis (CA) remains a management challenge, often requiring high dose diuretics and frequent hospitalizations. Innovative outpatient strategies are needed to effectively manage heart failure (HF) in patients with CA. Ambulatory diuresis has not been well studied in restrictive cardiomyopathy. Therefore, we aimed to examine the outcomes of an ambulatory diuresis clinic in the management of congestion related to CA. METHODS AND RESULTS: We retrospectively studied patients with CA seen in an outpatient HF disease management clinic for (1) safety outcomes of ambulatory intravenous (IV) diuresis and (2) health care utilization. Forty-four patients with CA were seen in the clinic a total of 203 times over 6 months. Oral diuretics were titrated at 96 (47%) visits. IV diuretics were administered at 56 (28%) visits to 17 patients. There were no episodes of severe acute kidney injury or symptomatic hypotension. There was a significant decrease in emergency department and inpatient visits and associated charges after index visit to the clinic. The proportion of days hospitalized per 1000 patient days of follow-up decreased as early as 30 days (147.3 vs 18.1/1000 patient days of follow-up, P< .001) and persisted through 180 days (33.6 vs 22.9/1000 patient days of follow-up, P< .001) pre- vs post-index visit to the clinic. CONCLUSIONS: We demonstrate the feasibility of ambulatory IV diuresis in patients with CA. Our findings also suggest that use of a HF disease management clinic may reduce acute care utilization in patients with CA. Leveraging multidisciplinary outpatient HF clinics may be an effective alternative to hospitalization in patients with HF due to CA, a population who otherwise carries a poor prognosis and contributes to high health care burden.

RESUMO

Patients with heart failure (HF) who are seen in an intensive care unit (ICU) manifest the highest-risk, most complex and most resource-intensive disease states. These patients account for a large relative proportion of days spent in an ICU. The paradigms by which critical care is provided to patients with HF are being reconsidered, including consideration of various multidisciplinary ICU staffing models and the development of acute-response teams. Traditional HF quality initiatives have centered on the peri- and postdischarge period in attempts to improve adherence to guideline-directed therapies and reduce readmissions. There is a compelling rationale for expanding high-quality efforts in treating patients with HF who are receiving critical care so we can improve outcomes, reduce preventable harm, improve teamwork and resource use, and achieve high health-system performance. Our goal is to answer the following question: For a patient with HF in the ICU, what is required for the provision of high-quality care? Herein, we first review the epidemiology of HF syndromes in the ICU and identify relevant critical care and quality stakeholders in HF. We next discuss the tenets of high-quality care for patients with HF in the ICU that will optimize critical care outcomes, such as ICU staffing models and evidence-based management of cardiac and noncardiac disease. We discuss strategies to mitigate preventable harm, improve ICU culture and conduct outcomes review, and we conclude with our summative vision of high-quality of ICU care for patients with HF; our vision includes clinical excellence, teamwork and ICU culture.

RESUMO

Making sense of service users' accounts of their mental health problems requires a method able to deal with complexity. Yet the different underlying epistemological and ontological positions of the methods researchers use, based, for example, on biomedicine or social constructionism, produce highly partial analyses. Addressing this problem, this article offers a method of Critical Realist Discourse Analysis (CRDA) that employs a synthesized discourse analysis, informed by critical realism, to examine the discursive, material, embodied, and institutional factors that might inform how mental health service users make sense of their mental health problems and associated service use. The article describes the epistemological/ontological underpinnings of CRDA and its three-phase methodology, before showcasing the method using, as examples, two data sets from care leavers and mothers. With our CRDA, we demonstrate a method for analyzing the complexity of interacting factors informing service users' understanding of their mental health problems.

RESUMO

Hemophagocytic lymphohistiocytosis (HLH) is a rare, potentially fatal, syndrome of excessive and ineffective activation of the immune system. The majority of the reported data on HLH is from pediatric patients and lacks specificity. This makes HLH diagnosis challenging especially in adults where HLH is triggered by many conditions and can resemble many disease entities. Elevated ferritin is one of the diagnostic criteria for HLH. We determined the conditions associated with elevated ferritin at our medical center to assess how specific ferritin is for predicting HLH. We retrospectively reviewed all ferritin results >10,000 µg/L in pediatric and adult patients. The most common condition associated with elevated ferritin was hematologic malignancy in adults (25.7%) and HLH in pediatric patients (48.9%). HLH was diagnosed in 14.2% of adults and 48.9% of children with ferritin >10,000 µg/L. Hyperferritinemia occurs in a variety of conditions and is not specific for adult or pediatric HLH. Common causes of elevated ferritin should be considered before entertaining the possibility of HLH, especially in adult patients.

RESUMO

BACKGROUND: The relative efficacy of the addition of induction chemotherapy to chemoradiotherapy compared with chemoradiotherapy alone for patients with head and neck cancer is unclear. The PARADIGM study is a multicentre open-label phase 3 study comparing the use of docetaxel, cisplatin, and fluorouracil (TPF) induction chemotherapy followed by concurrent chemoradiotherapy with cisplatin-based concurrent chemoradiotherapy alone in patients with locally advanced head and neck cancer. METHODS: Adult patients with previously untreated, non-metastatic, newly diagnosed head and neck cancer were eligible. Patients were eligible if their tumour was either unresectable or of low surgical curability on the basis of advanced tumour stage (3 or 4) or regional-node stage (2 or 3, except T1N2), or if they were a candidate for organ preservation. Patients were randomly assigned (in a 1:1 ratio) to receive either induction chemotherapy with three cycles of TPF followed by concurrent chemoradiotherapy with either docetaxel or carboplatin or concurrent chemoradiotherapy alone with two cycles of bolus cisplatin. A computer-generated randomisation schedule using minimisation was prepared and the treatment assignment was done centrally at one of the study sites. Patients, study staff, and investigators were not masked to group assignment. Stratification factors were WHO performance status, primary disease site, and stage. The primary endpoint was overall survival. Analysis was by intention to treat. Patient accrual was terminated in December, 2008, because of slow enrolment. The trial is registered with ClinicalTrials.gov, number NCT00095875. FINDINGS: Between Aug 24, 2004, and Dec 29, 2008, we enrolled 145 patients across 16 sites. After a median follow-up of 49 months (IQR 39-63), 41 patients had died-20 in the induction chemotherapy followed by chemoradiotherapy group and 21 in the chemoradiotherapy alone group. 3-year overall survival was 73% (95% CI 60-82) in the induction therapy followed by chemoradiotherapy group and 78% (66-86) in the chemoradiotherapy alone group (hazard ratio 1·09, 95% CI 0·59-2·03; p=0·77). More patients had febrile neutropenia in the induction chemotherapy followed by chemoradiotherapy group (16 patients) than in the chemoradiotherapy alone group (one patient). INTERPRETATION: Although survival results were good in both groups there was no difference noted between those patients treated with induction chemotherapy followed by chemoradiotherapy and those who received chemoradiotherapy alone. We cannot rule out the possibility of a difference in survival going undetected due to early termination of the trial. Clinicians should still use their best judgment, based on the available data, in the decision of how to best treat patients. The addition of induction chemotherapy remains an appropriate approach for advanced disease with high risk for local or distant failure. FUNDING: Sanofi-Aventis.

RESUMO

OBJECTIVE: Adherence to healthy lifestyle advice is effective in prevention of non-communicable diseases like coronary heart disease (CHD). Yet patient disengagement is the norm. We take a novel discursive approach to explore patients' negotiation of lifestyle advice and behaviour change. METHOD: A discourse analysis was performed on 35 longitudinal interviews with 22 heterosexual British people in a long-term relationship, where one had a diagnosis of CHD. The analysis examined the relationships between patients' constructions of expert knowledge and the implications of these accounts for patients' dis/engagement with lifestyle advice. RESULTS: Expert knowledge was constructed in four ways: (1) Expert advice was valued, but adherence created new risks that undermined it; (2) expert knowledge was problematised as multiple, contradictory, and contested and therefore difficult to follow; (3) expert advice was problematised as too generalised to meet patients' specific needs; and (4) expert advice was understood as limited and only one form of valued knowledge. CONCLUSION: Patients and partners simultaneously valued and problematised expert knowledge, drawing on elaborate lay epistemologies relating to their illness which produced complex patterns of (dis)engagement with expert lifestyle advice. Recognition of the multiple and fluid forms of knowledge mobilised by CHD patients could inform more effective interventions.

RESUMO

We investigated the impact of COVID-19 restrictions on the duration of untreated psychosis (DUP). First-episode psychosis admissions (n=101) to STEP Clinic in Connecticut showed DUP reduction (p=.0015) in the pandemic, with the median reducing from 208 days during the pre-pandemic to 56 days in the early pandemic period and subsequently increasing to 154 days (p=.0281). Time from psychosis onset to anti-psychotic prescription decreased significantly in the pandemic (p=.0183), with the median falling from 117 to 35 days. This cohort study demonstrates an association between greater pandemic restrictions and marked DUP reduction and provides insights for future early detection efforts.

RESUMO

We examined the effects of an early detection (ED) campaign (Mindmap), that successfully shortened the duration of untreated psychosis (DUP), on patient presentation profiles at two receiving coordinated specialty care (CSC) services. Data were collected between 2015 and 2019 during a test of ED delivered at one CSC (STEP, n = 147) compared to usual detection at another CSC (PREP, n = 63). Regression models were used to test the effects of ED and DUP on presentation. Before the launch of ED, there were no differences in presentation between STEP and PREP. However, the ED changed the profile of presentations to STEP such that patients were admitted with better negative and total symptoms scores, but worse GAF current and GAF social and with a greater decline in function over the prior year (GAF-Δ). Site-by-time interaction effects were not significant. During the campaign years, STEP vs. PREP recruited patients with better negative and total symptoms, GAF role, and pre-morbid adjustment scores but with worse positive symptoms, GAF current, and GAF-Δ. Nonetheless, mediation analysis revealed that DUP reduction accounted for very little (<8 %) of these differences in presentation. Early detection campaigns while successfully reducing access delays, can have salutary effects on presentation independent of DUP reduction.

RESUMO

OBJECTIVES: Healthy lifestyle change improves outcomes in coronary heart disease (CHD), but is rarely sustained. To better understand barriers to lifestyle change, we examined couples' talk of engaging with lifestyle advice after one partner receives a diagnosis of CHD. DESIGN: A longitudinal qualitative design, in which a poststructuralist discourse analysis was performed on 35 interviews, conducted with 22 heterosexual British people in a long term relationship. The interviews occurred over three months after one partner was referred to a cardiac rehabilitation programme designed to support lifestyle change. RESULTS: Couples understood their health as a shared practice underpinned by an ideological framework of healthism, creating a form of 'relational healthism'. Practicing relational healthism was not straightforward because the practices of surveillance, control, and discipline related to healthism often contravened relationship norms of support, acceptance and respect for the other's autonomy. Couples struggled to resolve this tension, dynamically adopting, resisting, and occasionally transforming discourses of health and love in ways that worked for and against engagement in lifestyle change. CONCLUSION: In foregrounding the discursive and relational contexts of behavioural change engagement, we show the considerable complexity for couples, including costs related to engagement with lifestyle advice.

RESUMO

Engagement with a first episode-psychosis service (FES) reduces the risk of psychiatric hospitalization. However, the role of the duration of untreated psychosis (DUP) in impacting this outcome is disputed. This study aimed to examine whether DUP was an effect modifier of the post-FES reduction of risk of hospitalization, and to explore associations between patients' characteristics and hospitalization post-FES. Individuals aged 16-35 with recent onset (< 3 years) of non-affective psychosis, admitted to the Program for Specialized Treatment Early in Psychosis (STEP), a FES serving the Greater New Haven area, Connecticut, between 2014 and 2019 were included (N = 189). Medical records were queried from 2013 through 2020 for number and duration of psychiatric hospitalizations. Poisson regression models were used to estimate incidence rate ratios for hospitalization rates across all explanatory variables. Negative binomial regression was used to compare the length of stay (LOS) before vs after STEP enrollment. STEP admission was associated with a significant 90 % reduction in the frequency and duration of hospitalizations. This effect was moderated by DUP: with 30-day prolongations in components of DUP (supply, demand, and total) there was less reduction in hospitalizations and LOS after FES enrollment (p < .0001). Only DUP supply (time from first antipsychotic use to STEP admission) differentiated those who were hospitalized during the first year after STEP enrollment from those who were not (median: 35 vs. 15 weeks, p = .003). To fully harness the positive impact of FES on hospitalization, a detailed effort should be pursued to reduce all DUP components.

RESUMO

Medical professionalism has been notoriously difficult to define and remains poorly understood. Because of this, graduates often have contrasting views on how it is best taught. These views should be considered and incorporated into teaching methods in order to enhance learning and development. Over a six-month consecutive period doctors and medical students in County Durham and Darlington Foundation Trust completed a questionnaire asking them to define professionalism, state where they felt they had learnt about professionalism and how important they feel professionalism is to them. They were also asked to identify how they felt teaching about professionalism was best delivered from a selection of educational resources. The findings highlight major differences between how the material is taught and how students and graduates feel they learn best about professionalism and more research into this field is needed.

RESUMO

This research examines how homeowners and renters were impacted by the financial crisis in 2009. We build from the hypothesis that homeownership provides people a sense of stability which decreases the extent to which they feel stressed as a result of financial hardship. Our study tests whether owning a home affected either the degree to which lower-income households experienced financial hardship or the extent to which they perceived they were financially stressed. Using a sample of lower-income borrowers who obtained affordable mortgages through the Community Advantage Program (CAP) and a comparison panel of renters, we collected data on the effects of the financial crisis. From a portfolio performance standpoint, CAP loans have performed relatively well. Our analysis of the survey data finds that, although both renters and owners experienced similar levels of financial hardship, the homeowners were less psychologically stressed overall and reported feeling more satisfied with their financial situation.

RESUMO

Objectives: Menstruation tracking digital applications (MTA) are a popular technology, yet there is a lacuna of research on how women use this technology for the management of PMS. Theoretical frameworks for understanding users' experiences are also underdeveloped in this nascent field. The objectives of the study were therefore twofold, to propose a theoretical framework for understanding women's use of MTA and apply it to the analysis of users' experiences in the management of PMS. Method: A novel theoretical framework was proposed, informed by post-phenomenology, postfeminist healthism, feminist new materialism and digital health technologies as public pedagogy. This framework focuses analytic attention on affective relationships between subjectivity, bodily sensations, digital technology, and discourse. It was used to structure the analysis of five in-depth timeline interviews with women in Aotearoa New Zealand who experienced benefits from using MTA to manage PMS symptoms. Results: Three pedagogical relationships were identified: a pedagogy of empowerment, where users learnt to control, predict and manage their PMS symptoms in line with healthism; a pedagogy of appreciation, where users learnt to understand their menstruating bodies as amazing, a valued part of them, and awe-inspiring that radically overturned past internalised stigma; and an 'untrustworthy teacher' who eroded this affirmative learning through inaccuracy, positioning users in dis-preferred categories, or being 'creepy'. Conclusions: MTA offers huge possibilities for challenging menstrual stigma that need to be nurtured, developed, and protected; and there are benefits for analysing MTA within wider scholarship on postfeminist healthism.

RESUMO

This case report describes a woman with no psychiatric history and previously diagnosed Hashimoto's thyroiditis who presented to the psychiatric emergency department with a first episode of psychosis. The initial workup for organic causes of psychosis revealed an astronomically high thyroid stimulating hormone (TSH) (> 1,000 µIU/mL) out of proportion to the patient's minimal physical symptoms of hypothyroidism. Additionally the patient's head imaging showed an enlarged pituitary, a rare, but reversible, presentation of chronically untreated primary hypothyroidism. The patient was transferred to a medical unit to receive IV thyroid hormone replacement as well as an adjunctive antipsychotic to assist with remission of her distressing auditory hallucinations and persecutory delusions. This case highlights the importance of a thorough medical workup for causes of new onset psychosis and the need for further consensus in the literature regarding choice of antipsychotic and duration of treatment for psychosis secondary to hypothyroidism.

RESUMO

BACKGROUND: Drug screening by immunoassay is common in pediatric populations. However, false-positive and -negative results due to antibody cross-reactivity and dilute urine are frequent and underappreciated. Accurate ascertainment of drug exposure in children has significant clinical and medico-legal consequences. DESIGN AND METHODS: We developed and characterized an LC-MS/MS drug screening assay to supplant immunoassay and detect 38 compounds at the lowest concentrations distinguishable from analytic noise. Once implemented, we conducted a retrospective analysis of 3985 pediatric urine drug screens performed a year before (n = 1663) and after (n = 2322) implementation to examine the frequency and breadth of drug detection in our pediatric population. RESULTS: Using immunoassay, 23% (293/1269) of samples from the general pediatric and 37% (147/394) of nursery populations had presumptively positive results. Of the presumptive positive compounds, 85% (288/338) from the general pediatric population and 40% (65/162) from the nursery cohort were confirmed by mass spectrometry. After LC-MS/MS implementation, 31% (628/2052) of general pediatric, and 18% (48/270) of the nursery samples were positive for 1 or more compounds. In the nursery population, immunoassays over-detected the presence of THC but under-detected exposure to cocaine. CONCLUSION: A broadly targeted, analytically sensitive LC-MS/MS drug screening assay detects a larger number and variety of compounds in a single step compared to a screen-then-confirm approach initiated by immunoassay in our pediatric population. Rapid delivery of accurate results enables timely, appropriate disposition of patients in a variety of settings including the emergency department and labor/delivery.

RESUMO

A burgeoning body of literature shows a positive relationship between body functionality and positive body image. Although still nascent, research centring experiences of people with disabilities and bodily differences develops this literature. In this article, we offer directions for this research, bringing body functionality into dialogue with feminist materialist disability theory to examine relations between people's bodily perceptions and the socio-material worlds they occupy. Feminist disability theory re-imagines difference through an affirmative lens, conceptualising body image as relational and processual, and approaching difference through four orientations: difference is basic to the world; difference is not deficiency; difference is not the problem, our inhospitable and ableist world is; and centring difference exposes the mythical norm. We apply this lens to body functionality research, and outline implications for research, practice, and theory, arguing that building a bridge between these frameworks offers a stepping off point for exciting directions for body image research.

RESUMO

Gabapentin (Neurontin) is an anti-epileptic drug that has had wide off-label prescription use since market release due to presumed negligible abuse potential. However, trends in drug misuse have demonstrated that gabapentin misuse is occurring, particularly in those with a history of opioid misuse. This is concerning, because although gabapentin has no direct ligand activity at opioid receptors, it does potentiate the analgesic effect of opioids, and concurrent use of gabapentin and opioids may increase the risk of respiratory depressive effects of opioids. This study investigates the incidence of gabapentin detected in urine samples collected for clinical drug screening purposes in a local hospital emergency department and in postmortem samples submitted by medical examiners in the St. Louis metropolitan area. The prevalence of gabapentin and co-detected drugs in both populations is contrasted, compared, and discussed. This study found that 30% of urine samples collected from patients with suspected drug intoxication presenting to SSM Health Saint Louis University Hospital, a quaternary care medical center, were positive for gabapentin, and nearly two thirds of those were also positive for oxycodone. Over a 6-month period, the incidence of gabapentin positive postmortem cases increased from 18% to 20%. Nearly all gabapentin positive postmortem cases were also positive for an opioid, the most significant being fentanyl, suggesting that gabapentin misuse may be due to its potentiating effect of opioid drug action. This study also highlights the limited utility of immunoassay-based urine drug screens.
