Observed Use of Clinical Judgment Among New Graduate Nurses

BACKGROUND

Despite the efforts of academic nursing educators to prepare students to make sound clinical judgments, the literature suggests new graduate nurse (NGN) competence with this critical skill continues to decline. This study sought to identify how practicing nurses describe their observations of the use and outcomes of clinical judgment by NGNs in nursing practice.

METHOD

A multisite, cross-sectional survey using multiple-choice, Likert scale, and open response items to identify participants' observations of NGN clinical judgment was sent with snowball sampling and resulted in a sample of 314 participants from 19 U.S. states.

RESULTS

Practice partners identified a wide discrepancy between how they expect NGNs to use clinical judgment and what they actually see NGNs do, with resultant negative effects on patients and NGNs.

CONCLUSION

These results provide a beginning understanding of NGNs' specific challenges with clinical judgment. Efforts to improve clinical judgment across nursing education and practice are needed. [J Contin Educ Nurs. 202x;5x(x):xx-xx.].

The Lasater Clinical Judgment Rubric: 17 Years Later

BACKGROUND

Nearly 17 years ago, the Lasater Clinical Judgment Rubric (LCJR) was published to provide a common language and trajectory of students' development to think like a nurse.

METHOD

This article traces the uses of the LCJR from creation to the present and cites lessons learned from its use.

RESULTS

During the intervening years, the LCJR has been used effectively as a debriefing guide in simulation and as a research instrument, as well as for formative assessment. The LCJR has been translated or is in process in 19 languages besides English.

CONCLUSION

This article provides evidence of the efficacy of the LCJR and discusses important lessons learned. [J Nurs Educ. 2024;63(3):149-155.].

An integrative review of teaching strategies to support clinical judgment development in clinical education for nurses

OBJECTIVES

Historically, emphasis on task-completion and lack of intentional approaches that develop students' thinking skills have dominated clinical education. One contributing factor may be the limited literature about teaching to develop clinical reasoning and clinical judgment in the clinical environment. This integrative review accessed available literature to answer the question, What strategies are used to develop clinical judgment in the clinical education environment?

DESIGN

The Whittemore and Knafl approach framed the integrative review. The framework includes the following steps 1) problem identification, 2) literature search, 3) data evaluation, 4) data analysis, and 5) presentation.

DATASOURCES

The data bases CINAHL Plus with Full Text, OVID, and ProQuest were searched through the period of January 2000 through July of 2022.

REVIEW METHODS

The PRISMA protocol informed review and screening of the literature. Authors assessed articles for eligibility via first screening by abstract review, followed by review of the full text. Both authors reviewed the articles, assessing qualification for inclusion and evaluating the content. Data from eligible articles were analyzed and synthesized to answer the research question.

RESULTS

Of the initial 427 articles, a total of 20 articles met inclusion criteria for final analysis. Five general themes emerged for clinical judgment during clinical education. The findings identified the teaching strategies nurse educators use. Many of the teaching methods include deliberateness and intentionality in planning and implementing the strategies. In addition to evaluating clinical judgment, nurse educators guided and mentored student thinking. Finally, this review identified reported outcomes and results of the teaching strategies and methods.

CONCLUSIONS

A limited number of articles describing teaching for clinical judgment in clinical environment were found. The articles analyzed found that nurse educators used a variety of teaching strategies for the purpose of developing students' clinical judgment. More research is needed to guide best-practices in clinical education. We must move the science forward to transform and leverage clinical education more deliberately to teach thinking in practice and decision-making about patient care.

Diagnostic accuracy of BASIC-Q for detection of cognitive impairment in a primary care setting - a cross-validation study

OBJECTIVES

This study aims to evaluate the diagnostic accuracy and reliability of a new, brief questionnaire, 'Brief Assessment of Impaired Cognition- Questionnaire' (BASIC-Q) for detection of cognitive impairment, primarily developed for use in primary care. BASIC-Q has three components: Self-report, Informant report, and Orientation. Self-report and Orientation are completed by the individual and Informant report is answered by a close relative.

METHODS

We included 275 participants ≥ 70 years, without a prior diagnosis of dementia, and with a close relative who agreed to participate as an informant. Participants were included prospectively in 14 general practices in urban and rural Denmark using a convenience sampling method. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), the informant-completed Functional Activities Questionnaire (FAQ) and reported memory concern were used as a reference standard for the classification of the participants' cognitive function.

RESULTS

BASIC-Q demonstrated a fair to good diagnostic accuracy to differentiate between people with cognitive impairment and normal cognition with an area under the ROC curve (AUC) of 0.84 (95% CI 0.79-0.89) and a sensitivity and specificity of 0.80 (95% CI 0.72-0.87) and 0.71 (95% CI 0.63-0.78). A prorated BASIC-Q score derived from BASIC-Q without Informant report had significantly lower classification accuracy than the full BASIC-Q. The test-retest reliability of BASIC-Q was good with an intraclass correlation coefficient of 0.84.

CONCLUSION

BASIC-Q is a brief, easy-to-use questionnaire for identification of cognitive impairment in older adults. It demonstrated fair to good classification accuracy in a general practice setting and can be a useful case-finding tool when suspecting dementia in primary health care.

Disparities in alcohol- and substance-related hospitalizations and deaths across sexual orientations in Canada: a longitudinal study

OBJECTIVES

We aim to quantify disparities in substance-related acute events (i.e. hospitalizations and deaths for substances, including alcohol, cannabis, opioids, narcotics, and/or illicit drugs) across sexual orientations based on health administrative data.

STUDY DESIGN

This was a longitudinal analysis from six waves of the Canadian Community Health Survey (2009-2014) linked to hospitalization/mortality data in Ontario, Canada.

METHODS

The study sample consisted of survey respondents aged ≥15 (weighted n = 15,406,000) who provided a valid response to the question about sexual orientation. The primary outcome was substance-related acute events, including hospitalizations and deaths due to alcohol, cannabis, opioids, narcotics, and/or illicit drugs. Disparities in substance-related acute events across sexual orientation and gender were examined using flexible parametric survival analysis.

RESULTS

Bisexual women had hazard ratios of 2.46 (95% confidence interval: 1.46-4.15) for any substance-related acute event and 2.67 (95% confidence interval: 1.42-5.00) for non-alcohol substance acute events compared to heterosexual women. Lesbian women did not exhibit significant differences in acute event risk compared to heterosexual women. Gay and bisexual men demonstrated elevated but not statistically significant risks compared to heterosexual men.

CONCLUSIONS

Bisexual women face higher risks of substance-related acute events, potentially due to self-medication of unique stressors brought on by discrimination and isolation. Enhanced education and training for healthcare professionals are essential to increase awareness and sensitivity toward the heightened substance use risk among lesbian, gay, and bisexual individuals. Targeted interventions aimed at reducing substance use problems among bisexual individuals warrant increased funding and research.

Potential for prevention of dementia in Denmark

INTRODUCTION

According to previous estimates, 40% of dementia cases globally may be attributed to 12 potentially modifiable risk factors.

METHODS

We calculated national population attributable fractions (PAFs) for each risk factor and modeled the effects of proportional reductions in risk factor prevalence on dementia prevalence by calculating potential impact fractions (PIFs) for each factor.

RESULTS

The overall adjusted PAF for all risk factors was 35.2%. Physical inactivity, hearing loss, hypertension, and obesity accounted for 64% of the total prevention potential. The overall adjusted PIF was 4.1% at 10% risk factor prevalence reduction and 8.1% at 20% risk factor reduction.

DISCUSSION

Estimates of the potential for the prevention of dementia should be based on country-specific data on risk factor prevalence, as estimates based on global risk factor prevalence have limited relevance from a national perspective. Physical inactivity, hearing loss, hypertension, and obesity could be primary targets for prevention of dementia in Denmark.

HIGHLIGHTS

Overall adjusted PAF for potentially modifiable dementia risk factors was 35%. Physical inactivity, hearing loss, hypertension, and obesity had the largest prevention potential. Estimates of prevention potential should be based on national risk factor prevalence.

Creating a Learning Plan for Prelicensure Students in Primary Care Clinical Experiences

BACKGROUND

Registered nurses (RNs) working to the full scope of licensed practice can expand the capacity of the health care system and influence patient care quality. However, preparation of prelicensure nursing students to practice in primary care is particularly challenging due to curricular and practice site barriers.

APPROACH

As part of a federally funded project to expand the primary care RN workforce, learning activities to teach key concepts of primary care nursing were designed and implemented. Students studied the concepts while placed in a primary care clinical setting and debriefed in a topical, instructor-facilitated, seminar. Current and best practices in primary care were explored, compared, and contrasted.

OUTCOMES

Pre- and postsurveys revealed significant student learning related to selected primary care nursing concepts. Overall knowledge, skills, and attitudes increased significantly pre- to post-term.

CONCLUSION

Concept-based learning activities can effectively support specialty nursing education in primary and ambulatory care settings.

Validity of the Brief Assessment of Impaired Cognition case-finding instrument for identification of dementia subgroups and staging of dementia

BACKGROUND AND PURPOSE

The aims of this study were to examine the psychometric properties of the Brief Assessment of Impaired Cognition (BASIC) case-finding instrument in clinical settings focusing on (i) test-retest reliability, (ii) the discriminative validity of BASIC and its components for identification of Alzheimer disease (AD) dementia and non-AD dementia, and (iii) the association of expert clinical rating of cognitive status with BASIC performance.

METHODS

The test-retest reliability analysis was based on a sample of general practice patients (n = 59) retested with a mean interval of 19 days. Discriminative validity analyses and analysis of the association of cognitive status with BASIC performance were based on data from the primary validation study of BASIC in memory clinics.

RESULTS

The test-retest reliability of BASIC was high (r = 0.861). No significant difference in discriminative validity was found for identification of AD dementia (sensitivity = 0.99, specificity = 0.98) and non-AD dementia (sensitivity = 0.90, specificity = 0.98). All components of BASIC contributed to the high discriminative validity of both AD and non-AD dementia. BASIC performance was significantly correlated with expert clinical rating of the cognitive status of patients. A crude staging model for cognitive status using BASIC score intervals had superior classification accuracy (70%) compared to a Mini-Mental State Examination (MMSE) score range-based model (58% accuracy).

CONCLUSIONS

BASIC is a reliable and valid case-finding instrument for AD dementia and non-AD dementia in clinical settings. BASIC performance is significantly associated with the degree of cognitive impairment, and BASIC seems to be superior to MMSE for staging of impairment.

Current Practices for Teaching Clinical Judgment: Results From a National Survey

BACKGROUND

Safe patient care is closely linked to clinical judgment. Concerns about inadequate practice readiness and the impending inclusion of clinical judgment items on the NextGen NCLEX have resulted in increasing interest and publications about teaching clinical judgment. However, little is known about actual current practices for teaching this skill.

PURPOSE

This research describes findings about current strategies to teach clinical judgment used in US prelicensure nursing programs.

METHODS

Cross-sectional methodology was used to survey program deans and directors across the United States.

RESULTS

Programs are using multiple strategies to teach clinical judgment. The most common strategies used include case studies and simulation. Participants believed strategies have a positive impact on student thinking, practice readiness, and program outcomes. They described insights into implementation of teaching for clinical judgment.

CONCLUSION

The results of this research provide foundational data to inform current teaching practices and further research for this essential skill.

Social capital and STIs testing among young men in Stockholm, Sweden: A cross-sectional study

Background

Testing for sexually transmitted infections (STIs) is highly accessible in Sweden, but young men's testing rate is considerably lower than young women's. Social capital (SC) might shape people's STIs testing patterns. However, such association has not been studied among young men before. This study assessed the prevalence of different forms of SC and if they increase STIs testing among young men in Stockholm, Sweden.

Methods

This population-based cross-sectional study was conducted in 2018 and included 523 men aged 20-29 years living in Stockholm. Bonding SC (having helped someone; having received help; having someone to share inner feelings with), institutionalized trust SC (in school; healthcare; media) and STIs testing behavior (never tested, tested only in the last 12 months, only more than 12 months ago, or both before and after the last 12 months) were assessed. Weighted adjusted multinomial logistic regression tested the associations between SC and STIs testing.

Results

High levels of bonding SC (range: 86.5 - 95.5%), as well as trust in healthcare (76.7%) and school (64.8%) were reported. Having helped someone (aRRR 6.1, 95% CI 1.7 - 21.6), having received help (aRRR 8.1, 95% CI 2.6 - 24.7) and having someone to share feelings (aRRR 4.0, 95% CI 1.7 - 9.2) were associated with being tested for STIs more than 12 months ago. Trust in media was the only institutional trust significantly associated with STIs testing (tested in the last 12 months: aRRR 2.5, 95% CI 1.1 - 5.4; both before and after: aRRR 3.8, 95% CI 1.6 - 8.9).

Conclusions

Peer-to-peer interventions using bonding SC should be used to promote STIs testing. More studies are needed to understand how trust in media increases testing for STIs. Although trust in healthcare and school were not statistically associated with testing, the high overall trust in these institutions reported in our study could be harnessed to implement sexual education programs promoting STIs testing among young men.

Left atrial strain predicts heart failure in the general population

Background

Left atrial (LA) function has shown to be a significant predictor of cardiovascular outcomes. We sought to determine the prognostic value of LA strain in relation to incident heart failure (HF) in the general population.

Methods

The present study includes 3,540 participants from the general population without prevalent atrial fibrillation or HF. All participants underwent health examinations and echocardiography including measures of LA function by means of peak atrial longitudinal strain (PALS), peak atrial contraction strain (PACS), and LA strain during the conduit phase (LACS). Cox proportional hazards regressions were utilised to access the association between incident HF and LA strain parameters.

Results

Median age of the study population was 57 years (interquartile range: 40, 69) and 2,015 (57%) were female. During follow-up (median 5.4 years), 66 (2%) participants were diagnosed with HF. Participants who developed HF had lower PALS (26.4% vs. 36.6%, p<0.001), PACS (15.6% vs. 16.5%, p=0.016), and LACS (11.4% vs. 19.3%, p<0.001) at baseline. Lower values of all three LA strain parameters were associated with a higher risk of developing HF in univariable analysis (Figure 1 & 2). After multivariable adjustments for Framingham Risk Score and global longitudinal strain, PALS (HR=1.06, 95% CI [1.03; 1.09], p<0.001, per 1% decrease), PACS (HR=1.07, 95% CI [1.02; 1.12], p=0.003, per 1% decrease), and LACS (HR=1.05, 95% CI [1.01; 1.10], p=0.016, per 1% decrease) remained significantly associated with incident HF. However, in participants with normal-sized LA (LA volume index <34 ml/m2) and no ischemic heart disease (n=3,046), only PALS and PACS remained independent predictors of HF (Figure 2).

Conclusion

LA strain provides independent prognostic value regarding the risk of incident HF in the general population.

Danish Feasibility Study of a New Innovation for Screening and Brief Intervention for Alcohol Problems in Primary Care: The 15-method

Introduction

The 15-method: a new brief intervention tool for alcohol problems in primary care, has shown promising results in Sweden for mild to moderate alcohol use disorders.

Objectives

To evaluate the 15-method’s usability, organizational integration, and overall implementation feasibility in Danish general practice (GP) in preparation for a large-scale evaluation of the method’s effectiveness in identifying and treating alcohol problems in GP.

Methods

In the Central and Southern Region of Denmark, five general practices participated: seven doctors and eight nurses. Participants received half a day of training in the 15-method. Testing of implementation strategies and overall applicability ran for two months. A focus group interview, two individual interviews with the participating doctors, and five individual patient interviews concluded the study phase.

Results

indicate that implementation of the 15-method is feasible in Danish general practice. The healthcare professionals and patients were optimistic about the method and its possibilities. The method was considered a new patient-centred treatment offer and provided structure to a challenging topic. An interdisciplinary approach was much welcomed. Results indicate that the method is ready for large-scale assessment.

Conclusions

Implementation of the 15-method is considered feasible in Danish general practice, and large-scale evaluation is currently being planned. The results from the present feasibility study, and an overview of the large-scale evaluation, will be presented at the conference.

Gender differences in a clinical sample of 60+ year old patients receiving treatment for alcohol use disorder

Introduction

Gender differences have been found in treatment-seeking older adults with AUD, concerning areas such as quality of life, drinking patterns, and prevalence of AUD. However, little is known about how these gender differences may relate to treatment.

Objectives

To investigate gender differences in quality of life, problematic areas at treatment start, and subsequent choice of treatment, in a clinical sample of 60+ year old patients receiving treatment for AUD.

Methods

We will utilize data from the Elderly Study; a multi-national (USA, Germany, and Denmark), single-blind randomized controlled trial. Participants (n=693) were randomized to brief, outpatient treatment based on motivational enhancement therapy alone (4 sessions) or motivational enhancement therapy followed by a community reinforcement approach age-adapted to older adults (up to 8 sessions). The latter was a module-based treatment where participants chose which module(s) they deemed most relevant. Modules focused on coping with aging, building sober networks, mood management, etc. The gender differences at baseline will be described by means of descriptive statistics (e.g. one-way analysis of variance, χ2 statistics, etc.). Gender differences, including choice of modules, will be investigated by means of multivariate statistics, e.g. generalized linear models. Analyses will be controlled for relevant confounders such as age, country, education, work situation, marital status, family and friends, type of housing, etc.

Results

Will be presented at the EPA Congress.

Conclusions

Will be presented at the EPA Congress.

Type of hormonal treatment administered to induce vitellogenesis in European eel influences biochemical composition of eggs and yolk-sac larvae

Egg biochemical composition is among the main factors affecting offspring quality and survival during the yolk-sac stage, when larvae depend exclusively on yolk nutrients. These nutrients are primarily embedded in the developing oocytes during vitellogenesis. In aquaculture, assisted reproduction procedures may be applied enabling gamete production. For the European eel (Anguilla anguilla), reproductive treatment involves administration of pituitary extracts from carp (CPE) or salmon (SPE) to induce and sustain vitellogenesis. In the present study, we compared the influence of CPE and SPE treatments on offspring quality and composition as well as nutrient utilization during the yolk-sac stage. Thus, dry weight, proximal composition (total lipid, total protein), free amino acids, and fatty acids were assessed in eggs and larvae throughout the yolk-sac stage, where body and oil-droplet area were measured to estimate growth rate, oil-droplet utilization, and oil-droplet utilization efficiency. The results showed that CPE females spawned eggs with higher lipid and free amino acid contents. However, SPE females produced more buoyant eggs with higher fertilization rate as well as larger larvae with more energy reserves (estimated as oil-droplet area). Overall, general patterns of nutrient utilization were detected, such as the amount of total lipid and monounsaturated fatty acids decreasing from the egg stage and throughout the yolk-sac larval stage. On the contrary, essential fatty acids and free amino acids were retained. Notably, towards the end of the yolk-sac stage, the proximal composition and biometry of surviving larvae, from both treatments, were similar.

Patients' assessment of care for type 2 diabetes: Results of the Patient Assessment of Chronic Illness Care scale in a Danish population

Background

The Patient Assessment of Chronic Illness Care (PACIC) scale is the most appropriate for assessing self-reported experience in chronic care. We aimed to validate the PACIC questionnaire by (1) assess patients’ perception of the quality of care for Danish patients with type 2 diabetes, (2) identify which factors are most important to the quality of care designated by the five subscales in PACIC, and (3) the validity of the questionnaire.

Methods

A survey of 7,745 individuals randomly selected from the National Diabetes Registry. Descriptive statistics inter-item and item-rest correlations and factor analysis assessed the PACIC properties. Quality of care was analysed with descriptive statistics; linear and multiple regression assessed the effect of forty-nine covariates on total and subscale scores.

Results

In total, 2,696 individuals with type 2 diabetes completed ≥ 50 % of items. The floor effect for individual items was 8.5–74.5 %; the ceiling effect was 4.1–47.8 %. Cronbach’s alpha was 0.73–0.86 for the five subscales. The comparative fit index (CFI) and the Tucker–Lewis index (TLI) were 0,87, and 0,84, respectively. Mean PACIC score was 2.44 (± 0.04). Respondents, who receive diabetes care primarily at general practice and outpatient clinics had higher scores compared to those receiving care at a private specialist. Receiving rehabilitation was followed by higher scores in all subscales. Those 70 years or older had lower mean total and subscale scores compared to younger patient groups.

A higher number of diabetes visits were associated with higher total scores; a higher number of emergency department visits were associated with lower total scores. The effects of healthcare utilisation on subscale scores varied.

Conclusions

These results provide insight into variations in the quality of provided care and can be used for targeting initiatives towards improving diabetes care. Factors important to the quality of perceived care are having a GP or hospital outpatient clinic as the primary organization. Also having a higher number of visits to the two organizations are perceived as higher quality of care as well as participating in a rehabilitation program. Floor and ceiling effects were comparable to an evaluation of the PACIC questionnaire in a Danish population. Yet, floor effects suggest a need for further evaluation and possible improvement of the PACIC questionnaire in a Danish setting. Total PACIC scores were lower than in other healthcare systems, possible being a result of different contexts and cultures, and of a need for improving diabetes care in Denmark.

Developing Students' Clinical Reasoning Skills: A Faculty Guide

BACKGROUND

Safe patient care relies on the ability of nurses to make timely, sound clinical judgments, yet new nurse graduates are underprepared. Nurse educators must take action with teaching to develop students' clinical reasoning skills and ultimately their clinical judgment. One first step is to consider strategies that integrate clinical judgment and clinical reasoning skills into nursing curriculum.

METHOD

The literature was reviewed to uncover what is known about teaching strategies that intentionally teach clinical reasoning skills and are focused on the development of students' clinical judgment.

RESULTS

Although not exhaustive, this guide for faculty discusses first steps when considering integrating clinical reasoning and judgment into nursing curriculum, presents teaching strategies, and provides ideas for implementation within nursing curriculum.

CONCLUSION

Teaching clinical reasoning skills, using a framework, and incorporating teaching strategies such as concept-learning, high-order questioning, and reflection focused on developing clinical reasoning skills may prove useful in developing students' clinical judgment.

P–617 Idiopathic early ovarian aging: Do biomarkers of ageing indicate premenopausal accelerated biological ageing in young women with diminished response to ART?

Study question

Do young women with idiopathic early ovarian ageing have changes in telomere length and epigenetic age indicating accelerated biological aging?

Summary answer

The telomere length and epigenetic age were comparable to those in young women with normal ovarian ageing.

What is known already

Increased risk of several health events usually considered to be age-related such as cardiovascular disease, osteoporosis, over-all morbidity and mortality have been associated with premature and early menopause when compared to the risk in women with normal menopausal age suggesting an accelerated general ageing process associated to early ovarian ageing. It is unclear whether the onset of this process may start before menopause.

Study design, size, duration

A prospective cohort study. Young women (≤ 37 years) having ART at two Danish Public fertility clinics during the period 2016 to 2018 were divided into two groups dependent on their ovarian reserve status: early ovarian ageing (EOA) (N = 55) and normal ovarian ageing (NOA)( N = 52). Number of oocytes harvested in first and subsequent cycles was used as a marker of ovarian reserve. Blood samples was drawn at time of oocyte retrieval to assess biological age.

Participants/materials, setting, methods

EOA was defined as ≥ 2 IVF cycles with ≤ 5 harvested oocytes despite sufficient stimulation with FSH and NOA as ≥ 8 oocytes harvested in minimum 1 cycle. Known causes influencing the ovarian reserve (endometriosis, ovarian surgery, etc.) was reason for exclusion. Relative telomere length (qPCR) and epigenetic age acceleration (DNA methylation levels) were measured in white blood cells as markers of accelerated biological ageing.

Main results and the role of chance

Relative telomere length was comparable with a mean of 0.46 (± sd 0.12) in the EOA group and 0.47 (0.14) in the normal ovarian ageing group (p = 0.64). The difference of predicted mean epigenetic age and mean chronological age (i.e. epigenetic age acceleration) was, insignificantly, 0.5 years older in the EOA group when compared to the NOA group( (–1.02 years (2.62) and –1.57 years (2.56), respectively, p = 0.27)), but this difference disappeared when adjusting for chronological age.

Limitations, reasons for caution

Discrete changes in epigenetic age acceleration may not have been captured as the study only had power to detect an age acceleration of ≥ 2 years.

Wider implications of the findings: By analysis of biomarkers for ageing in whole blood, we did not find any indications of a premenopausal accelerated aging in young women with idiopathic EOA. Further investigations in a similar cohort of premenopausal women is needed to fully elucidate the potential relationship between premenopausal accelerated biological ageing and EOA.

Trial registration number

The study was approved by the Danish Data protection Agency (nr 1–16–02–320–14) and the Regional committee on health research ethics of Central Region Denmark (jr.no 1–10–72–142–14).

Left atrial function assessed by speckle tracking echocardiography predicts atrial fibrillation burden after catheter ablation independently of reconduction: a RACE-AF echocardiographic sub-study

Funding Acknowledgements

Type of funding sources: None.

Background

Left atrial (LA) function assessed by 2D speckle tracking echocardiography (STE) has demonstrated to be a useful predictor of recurrence of atrial fibrillation (AF) following catheter ablation (CA). Pulmonary vein reconduction (PVR) is one of the most important causes of recurrent paroxysmal AF (PAF) after ablation. The purpose of this study was to evaluate the association between AF burden (% of time in AF) following CA and LA strain measurements independently of PVR.

Methods

This prospective study included 66 patients with PAF who underwent CA (mean age 60 ± 8 years, 65% male). STE was performed during sinus rhythm prior to CA. AF burden was recorded by continuous rhythm monitoring using implantable loop recorders during a follow-up period of 4-6 months, excluding a blanking period of 3 months. After follow-up, all patients underwent an invasive assessment of pulmonary vein isolation to test for PVR. Multivariable linear regression analysis was used to assess the association between AF burden and peak atrial longitudinal reservoir strain (PALS), peak atrial contraction strain (PACS) and peak atrial conduit strain (PCS).

Results

Prior to CA, median AF burden was 3.8% (IQR: 0.5, 17). During follow-up, 37 patients (56%) were free of AF while median AF burden was 0.7% (IQR: 0.2, 1.6) in patients with an AF burden of more than 0%. A total of 35 patients (54%) were found to have PVR after ablation. Patients with AF recurrence had significantly lower PACS compared to patients with no AF during follow-up (10% ± 6% vs. 14% ± 5%, p = 0.004). No differences in PALS and PCS were observed. Increased PACS remained independently associated with low AF burden following CA after multivariable adjustments for clinical characteristics, comorbidities, and PVR (β=-0.262, p = 0.049) (Figure 1). PALS and PCS did not remain significantly associated with AF burden.

Conclusion

Increased PACS is strongly associated with low AF burden after CA even after adjusting for PVR. This suggests that an analysis of LA function could be useful to stratify patients prior to CA and improve treatment strategies.

Yoga therapy DYADS: A novel approach to chronic pain management in underserved populations

Yoga therapy is an emerging integrative health approach that applies the practices and teachings of yoga for individuals with clinical concerns. It is generally offered as individual sessions between a yoga therapist and client or in a small group setting with several clients who share a clinical concern. Here we describe a third model for consideration- the yoga therapy dyad. A dyad includes two clients working simultaneously with a single yoga therapist and differs from both individual and small group sessions in the potential benefits and challenges. The yoga therapy dyad model that is detailed here was implemented as part of a feasibility trial along with group acupuncture therapy for chronic pain in an underserved population. Underserved populations are at risk for pain and reduced access to care. This pilot may inform future research, policy, education, and clinical practice.

Young men’s discourses of health service utilization for Chlamydia infection testing in Stockholm

Background

Chlamydia Trachomatis (CT) infection is the most commonly reported sexually transmitted bacterial disease in Sweden, other European countries, as well as globally. CT is often asymptomatic and if it goes untreated it can cause severe reproductive health issues. In Sweden, men test for CT in a much lesser extent than women. The aim of this study is to identify factors influencing Swedish young men to use Health care for CT detection.

Methods

Qualitative study based on 18 semi-structured interviews with young men (18-30 years old) in Stockholm during 2018. A Situational Analysis was conducted (a development of Constructivist Grounded Theory) of the interviews' transcriptions, using Open Code as the software for qualitative analysis in order to code and organize the information obtained. We constructed a situational map to illustrate the positions taken by Swedish young men according to their discourses.

Results

Three ideal types of Swedish young men with different discourses and behaviors towards CT testing were identified: unconcerned men are indifferent about CT and other sexual transmitted infections (STI) and therefore not testing; ambivalent men only test when suspect suffering from an STI and/or are influenced by their social network; Whereas, proactive men test regularly as a way to know they are healthy. The differences between the ideal types are explained by their risk perception, the role of health services, and the positive or negative influence of their social network.

Conclusions

The ideal types of young men identified in this study show a range of discourses linked to their risk perception, the role of health services, and the influence of their social network, which in practice is translated into different behaviours adopted for CT testing. Testing should be encouraged as an important part of CT prevention by educating groups of unconcerned young men about both the consequences of untreated CT and the free testing options available in Sweden.

Key messages

Swedish young men have different discourses towards CT testing depending on their risk perception, the strategies adopted to test and the positive or negative role of their social network. The role of health services and the social support emerged as key factors to promoting testing among Swedish Young men.

Validation of the Brief Assessment of Impaired Cognition and the Brief Assessment of Impaired Cognition Questionnaire for identification of mild cognitive impairment in a memory clinic setting

OBJECTIVES

The aim of this study was to validate the Brief Assessment of Impaired Cognition (BASIC) and the Brief Assessment of Impaired Cognition Questionnaire (BASIC-Q) for identification of mild cognitive impairment (MCI) in a memory clinic setting.

METHODS

A total of 163 sociodemographically matched patients (MCI, n = 42, and dementia, n = 121) and 83 control participants were included in the study. Two instruments were validated: (a) BASIC, including the components self-report, informant report, and two brief cognitive tests, and (b) BASIC-Q, including the components self-report, informant report, and orientation. BASIC can be administered in 5 minutes and BASIC-Q in less than 5 minutes.

RESULTS

A high discriminative validity for MCI vs control participants was found for both BASIC (sensitivity 0.86, specificity 0.89) and BASIC-Q (sensitivity 0.88, specificity 0.88). In comparison, the MMSE had low sensitivity (0.61) and moderate specificity (0.72). All components of BASIC and BASIC-Q contributed significantly to differentiate MCI from control participants. The components of BASIC and BASIC-Q also contributed significantly to differentiate MCI from dementia, except for self-report, which was identical in the two groups.

CONCLUSIONS

Both BASIC and BASIC-Q are brief, valid, and effective instruments for identification of patients with possible MCI in a memory clinic setting. Further cross-validation of the instruments in a general practice or primary care setting is needed.

Brief Assessment of Impaired Cognition Questionnaire (BASIC-Q)-Development and validation of a new tool for identification of cognitive impairment in community settings

OBJECTIVES

Brief Assessment of Impaired Cognition (BASIC), which combines self- and informant report with cognitive testing, was previously found to be highly accurate in identification of dementia and cognitive impairment. The aim of the present study was to develop and validate a questionnaire version of BASIC, the BASIC-Q, for use in community settings.

METHODS

In order to construct a questionnaire version of BASIC, we substituted cognitive testing with questions regarding orientation. BASIC-Q was validated based on further analysis of data from the primary BASIC validation study, where patients consecutively referred from general practice were tested at their first memory clinic admission prior to diagnosis. Control participants were primarily recruited among participating patients' relatives. Expert clinical diagnosis was subsequently used as reference standard for estimation of classification accuracy.

RESULTS

A high discriminative validity (sensitivity 0.92, specificity 0.97) for cognitive impairment (n = 159) vs socio-demographically matched control participants (n = 109) was found. In comparison, the MMSE had 0.76 sensitivity and 0.81 specificity. Administration time for BASIC-Q was less than 5 minutes compared to approximately 10 minutes for the MMSE.

CONCLUSIONS

BASIC-Q is a brief, efficient and valid tool for identification of cognitive impairment in a clinical setting. Further validation in a community setting is needed.

AB0209 PREDICTORS OF ACHIEVING STRINGENT REMISSION IN PATIENTS WITH ESTABLISHED RHEUMATOID ARTHRITIS IN CLINICAL REMISSION FOLLOWING A TREAT-TO-TARGET STRATEGY

Background:

Achieving remission according to stringent criteria such as Simplified Disease Activity Index (SDAI) and ACR/EULAR Boolean remission is associated with a better long-term outcome in patients with RA1. Possible predictors of achieving stringent remission in patients in clinical remission, following targeted treatment strategies, have not been investigated.

Objectives:

To investigate the predictive value of clinical, radiographic and MRI variables on achieving more stringent remission in RA patients in clinical remission, following MRI and conventional treat-to-target (T2T) strategies.

Methods:

In this post-hoc study, data were used from 171 RA patients in clinical remission (DAS28-CRP< 3.2 and no swollen joints) on conventional synthetic DMARDs, included in the IMAGINE-RA randomized clinical trial2, where they followed an MRI T2T strategy (targeting absence of osteitis) combined with clinical remission (DAS28-CRP≤3.2 and no swollen joints) or a conventional T2T strategy (targeting clinical remission only). Baseline contrast-enhanced MRIs of the dominant wrist and 2nd-5thMCP joints and radiographs of hands and feet were evaluated according to the OMERACT RAMRIS scoring system and Sharp/van der Heijde method, respectively, by two experienced readers. Potential clinical, radiographic and MRI baseline predictors of remission were first tested in univariate logistic regression analyses with achievement of Clinical Disease Activity Index (CDAI), SDAI, and ACR/EULAR Boolean remission at 24 months as dependent variables. Variables with p<0.25 were subsequently tested in multivariate logistic regression analyses with backward selection, adjusted for age, gender and strategy group. Missing values of covariates were imputed using chained equations.

Results:

Based on the univariate analyses, tender joint count, patient VAS global, VAS pain, VAS fatigue, physician VAS global, HAQ, MRI osteitis, radiographic and MRI erosion and joint space narrowing scores were included in multivariate analyses (Table).

Following the MRI T2T strategy was a positive predictor and high patient VAS global a negative predictor of achieving all definitions of remission. Furthermore, high patient VAS pain was negatively associated with achieving SDAI and ACR/EULAR Boolean remission and high tender joint count negatively associated with achieving CDAI and SDAI remission.

Conclusion:

In RA patients in clinical remission, poor patient reported outcomes and tender joint count were associated with decreased chance of achieving stringent remission, while following an MRI T2T strategy predicted stringent remission across all definitions thereof.

FRI0019 MRI INFLAMMATION, DISEASE ACTIVITY AND FUNCTIONAL IMPAIRMENT ARE MORE EFFECTIVELY REDUCED BY ESCALATION TO BIOLOGICS COMPARED TO CSDMARD-ESCALATION IN RHEUMATOID ARTHRITIS PATIENTS IN CLINICAL REMISSION FOLLOWING A TREAT-TO-TARGET STRATEGY: SECONDARY ANALYSES OF THE IMAGINE-RA TRIAL

Background:

The effect of different treatment escalations on MRI inflammation in rheumatoid arthritis (RA) patients following an MRI treat-to-target (T2T) strategy has not previously been investigated.

Objectives:

To compare the effect of different treatment escalations on MRI inflammation, physical function and disease activity in RA patients in clinical remission, following an MRI T2T strategy.

Methods:

One hundred RA patients in clinical remission (DAS28-CRP<3.2 and no swollen joints), on conventional synthetic (cs) DMARDs following an MRI T2T strategy targeting DAS28-CRP≤3.2, no swollen joints plus absence of MRI osteitis, were followed for 2 years with clinical and MRI (wrist and 2nd-5thMCP joints) evaluation every 4 months1. If target was not met, a predefined treatment escalation algorithm dictated: First: increase in csDMARDs (A), second: adding a TNF inhibitor (TNFi) (B), third and onwards: switch between biologics (C). If target was met, no change in baseline csDMARDs was done (D). Outcomes were assessed 4 months after treatment change. MRIs were evaluated with known chronology by one experienced reader. Repeated measures mixed linear models were used to express estimates of group differences on predefined co-primary outcomes (MRI osteitis, HAQ) and key secondary outcomes (MRI combined inflammation, Simplified Disease Activity Index (SDAI)).

Results:

Escalation to first TNFi (B) or to 2ndor later biologic (C) compared to csDMARDs (A) was consistently more effective on all outcomes (e.g. in group B osteitis was reduced with 1.8 units more than A) (Table). Unchanged (D) compared to escalation in csDMARD (A) treatment did not differ, except for HAQ-score. Escalation to a 2ndor later biologics (C) compared to the first TNFi (B) was more effective suppressing MRI inflammation. Escalation to TNFi treatment (B) or to 2ndor later biologic (C) compared to unchanged treatment (D) was more effective on all outcomes except from HAQ-score (no difference between groups).

Chronic Diseases in High-Cost Users of Hospital, Primary Care, and Prescription Medication in the Capital Region of Denmark

BACKGROUND

A small proportion of patients account for the majority of health care costs. This group is often referred to as high-cost users (HCU). A frequently described characteristic of HCU is chronic disease. Yet, there is a gap in understanding the economic burden of chronic diseases associated with HCU to different types of health care services.

OBJECTIVE

To analyze which frequent chronic diseases have the strongest association with HCU overall, and HCU in hospital, primary care, and prescription medication.

DESIGN

This is a register-based observational study on Danish health service costs for various diseases in different medical settings.

PARTICIPANTS

A total of 1,350,677 individuals aged ≥ 18 years living in the Capital Region of Denmark by 1 January 2012 were included.

MAIN MEASURES

Chronic diseases, costs, and sociodemographic data were extracted from the nationwide registers, including data from hospitals, primary care, and medicine consumption. These information were merged on an individual level.

KEY RESULTS

Cancer, mental disorders except depression, and heart diseases have the strongest association with HCU overall. Mental disorders except depression were in the three diseases most prevalent in HCU in all the three health care services.

CONCLUSIONS

Our results show that the chronic diseases that have the strongest association with HCU differ between different types of health care services. Our findings may be helpful in informing future policies about health care organization and may guide to different prevention, treatment, and rehabilitation strategies that could lessen the burden in the hospital.

Brief Assessment of Impaired Cognition (BASIC)-Validation of a new dementia case-finding instrument integrating cognitive assessment with patient and informant report

OBJECTIVES

The aim of this study was to develop and validate a new brief and accurate case-finding instrument for dementia and cognitive impairment. Previous research indicates that combining cognitive tests with informant and/or patient report may improve accuracy in dementia case-finding. The Brief Assessment of Impaired Cognition (BASIC) integrates these three sources of information.

METHODS

BASIC was prospectively validated in five memory clinics. Patients consecutively referred from general practice were tested at their initial visit prior to diagnosis. Control participants were primarily recruited among participating patients' relatives. Expert clinical diagnosis was subsequently used as gold standard for estimation of the classification accuracy of BASIC.

RESULTS

A very high discriminative validity (specificity 0.98, sensitivity 0.95) for dementia (n = 122) versus socio-demographically matched control participants (n = 109) was found. In comparison, the MMSE had 0.90 specificity and 0.82 sensitivity. Extending the discriminative validity analysis to cognitive impairment (both dementia and MCI, n = 162) only slightly reduced the discriminative validity of BASIC whereas the discriminative validity of the MMSE was substantially attenuated. Administration time for BASIC was approximately 5 minutes compared with 10 to 15 minutes for the MMSE.

CONCLUSIONS

BASIC was found to be an efficient and valid case-finding instrument for dementia and cognitive impairment in a memory clinic setting.

Do prelicensure nursing students' backgrounds impact what they notice and interpret about patients?

BACKGROUND

Academic educators are challenged to foster the development of clinical judgment in diverse learners. The impact of nursing students' backgrounds on clinical judgment has not previously been studied.

AIMS

SAMPLE: Prelicensure/preregistration students, representing three international English-speaking programs in 3 countries, comprised the sample (N = 532). All were enrolled in the first course in which perioperative content was taught.

DATA COLLECTION

An online learning activity was designed to elicit responses to a simulated case study of an expert nurse role model caring for an older adult patient experiencing delirium several days post-operatively.

DATA ANALYSIS

Dyads of coders did three rounds of coding. Logistic and multinomial logistic regression models used background variables to look for patterns in student responses.

FINDINGS

The data strongly suggest that background variables impact clinical judgment, however, not in interpretable patterns.

CONCLUSION

Nurse educators must acknowledge that prelicensure students' backgrounds impact their clinical judgment and assist them to learn to think like nurses.

Incorporating Group Interviews Into Holistic Review in Baccalaureate Nursing School Admissions

Holistic review in admissions considers an applicant's background and experience in combination with academic achievement. In order to evaluate baccalaureate nursing school applicants more holistically, a school of nursing added group interviews as part of the admissions process. The school's Admission and Progression Committee consulted with other schools, developed interview questions, and implemented a strategy to interview applicants. Results of this process were high levels of candidate and faculty satisfaction and enrollment of a diverse cohort of students with a high preadmission grade point average. Areas for improvement and further research are discussed.

Primary Malignant Lymphoma of the Salivary Glands

Five cases of primary malignant lymphomas of the salivary glands are reported. Four lymphomas arose in the parotid gland and one in the submandibular gland. All were non-Hodgkin lymphomas. In 4 cases the lymphomas were of low-grade malignancy, viz. 2 immunocytomas and 2 centroblastic/centrocytic malignant lymphomas, and 1 was a T-immunoblastic malignant lymphoma of high-grade malignancy. Four patients with localized disease were treated with radiotherapy and 1 patient with disseminated disease was treated with chemotherapy. One patient died from a disease unrelated to the malignant lymphoma, and 4 patients were alive at 66-136 months after treatment.

Abstract 664: Analytical validation and clinical utility of an immunohistochemical PD-L1 diagnostic assay for treatment with durvalumab in urothelial carcinoma patients

Background: A high quality programmed cell death ligand-1 (PD-L1) diagnostic may help to identify patients (pts) most likely to respond to anti-PD-L1/programmed cell death-1 (PD-1) therapy. Here we describe a PD-L1 immunohistochemical (IHC) diagnostic test developed for urothelial carcinoma (UC) pts treated with durvalumab.

Methods: The IHC assay uses an anti-human PD-L1 rabbit mAb optimized for detection of both tumor cell (TC) and tumor-associated immune cell (IC) PD-L1 expression with the OptiView DAB IHC Detection Kit on the automated VENTANA BenchMark ULTRA platform. The assay was validated for intended use in UC formalin-fixed, paraffin-embedded samples in a series of studies that addressed sensitivity, specificity, robustness and precision and implemented in Study CD-ON-MEDI4736-1108 (NCT01693562). Pts were evaluated using the VENTANA PD-L1 (SP263) Assay at a prespecified PD-L1 expression cut-off. Efficacy was analyzed in pts with PD-L1 low/negative (defined as TC &lt;25% and IC &lt;25%) UC and in pts with PD-L1 high (defined as TC ≥25% or IC ≥25%) UC.

Results: The VENTANA PD-L1 (SP263) Assay met all the predefined acceptance criteria (average positive agreement and average negative agreement &gt;85%), showing analytical specificity, sensitivity and precision. It demonstrated ≥97% and ≥85% inter-reader precision agreement for TC and IC respectively. For intra-reader precision, it demonstrated &gt;96% and &gt;87% agreement for TC and IC respectively. For intra-day performance, the assay demonstrated ≥96% agreement for TC and IC and for inter-day performance, it demonstrated ≥98% and 100% agreement for TC and IC respectively. Precision studies for inter-antibody lot, inter-detection kit lot and intra-platform demonstrated &gt;97% agreement for both TC and IC. Inter-laboratory testing was performed at 3 external laboratories and demonstrated an overall agreement rate of 92.3%. The VENTANA PD-L1 (SP263) Assay was implemented in Study CD-ON-MEDI4736-1108 and durvalumab demonstrated clinical activity and durability of response in both PD-L1 high and PD-L1 low/negative subgroups, yet with different response rates. In addition, given the high negative predictive value of the assay, it is especially helpful in evaluating the likelihood of response to durvalumab; pts who were classified as PD-L1 high with the VENTANA PD-L1 (SP263) Assay tended to have a higher objective response rate per RECIST v1.1 than pts who were PD-L1 low/negative.

Conclusions: These data show that determination of PD-L1 expression in TC and IC in UC pts using the VENTANA PD-L1 (SP263) Assay is precise and highly reproducible and highlight the utility of the assay in a clinical setting. The VENTANA SP263 Assay is especially helpful in informing pts and physicians on the likelihood of response to durvalumab, but not for the purpose of restricting treatment to only PD-L1 high pts.

Young age at first intercourse and subsequent risk-taking behaviour: An epidemiological study of more than 20,000 Danish men from the general population

Aim: First intercourse at the age of 14 years or younger is usually considered high-risk behaviour for sexually transmitted infections (STIs). It has been linked to other types of risky behaviour in women, while conflicting results have been obtained for men. The aim of the study was to estimate the prevalence of first intercourse at a young age in various birth cohorts of men and to determine any association with later risky behaviour. Methods: We studied 22,979 randomly selected men aged 18–45 years from the Danish general male population who responded to a self-administered questionnaire. Multiple sexual partners over a lifetime, multiple new sexual partners within the past 6 months, intercourse with a commercial sex worker, having an STI, binge drinking and current smoking were considered risky behaviour. Results: First intercourse at the age of 14 years or younger was more prevalent in younger (14%) than in older (10%) birth cohorts and among men with shorter schooling. Young age at sexual debut was associated with a more than twofold increase in the risks for subsequent risky behaviour. Conclusions: More than 10% of Danish men first had sex at an early age, and this was closely related to subsequent risk-taking behaviour.

Parental concerns about complementary feeding: differences according to interviews with mothers with children of 7 and 13 months of age

BACKGROUND/OBJECTIVES

To investigate and analyze differences in parental concerns during earlier and later phases of complementary feeding.

SUBJECT/METHODS

Eight focus group interviews were conducted with 45 mothers of children aged 7 or 13 months. Deductive and inductive coding procedures were applied in the analysis.

RESULTS

There were marked differences in mothers' health concerns in early and in later phases of complementary feeding. In the early phase, feeding a child healthy food was an unquestioned and self-evident practice. The child's food was a specific category, separated from the rest of the family's food, and the mother's focus was on the immediate well-being and safety of the child. In the later phase, health concerns shifted towards a longer-term perspective, and the aim of integrating the child into the family's social world became as important as concerns about well-being and safety. Contested and partly contradictory practices resulted, including conscious acceptance of some intake of sugar and unhealthy fats. Perceived relevance of nutritional guidelines on complementary feeding was high in the early phase but declined later.

CONCLUSION

Mothers' concerns and practices in the feeding of a young child vary considerably across the early and later phases of complementary feeding. This should be explored further and taken into consideration in the targeting and timing of dietary guideline communications.

Multiple-type human papillomavirus infection in younger uncircumcised men

A cohort of 388 young men enrolled for military service in the Danish army was established and the participants underwent a clinical examination with human papillomavirus (HPV) testing. In addition, a questionnaire containing questions regarding sociodemographic variables, sexual habits and lifestyle factors was completed. The prevalence of HPV was 33.4% in this cohort of uncircumcised men aged 18-29 years. Multiple HPV types were prevalent with one-third of the HPV-positive men being positive for more than one HPV type. Number of recent sexual partners and infrequent condom use were strong risk factors, particularly in men having multiple HPV types. Our findings re-emphasize the importance of sexual transmission and also point to a role of factors that may be related to individual susceptibility as genital warts, alcohol intake and, to a lesser extent, smoking were strongly associated with having multiple HPV types.
