Improving the quality of translation for patients with language barriers

Background

Patients with language barriers have worse health outcomes. To promote equitable care, efforts must be made to ensure effective communication with patients, including providing professional translation. In a busy, overstretched health service this can be difficult to achieve. Language translators can reduce barriers, improve safety and ensure impartiality.

Description of the Problem

Aims - To understand the quality of translation and explore interventions that could improve this in a busy diverse hospital in East London.

Methods

A quality improvement project in the Medical Admissions Unit of the Royal London Hospital was completed over two years. Patients with language barriers were identified, methods of translation were analysed and interventions to improve access to independent translation were introduced.

Results

Cycle 1- All medical admissions over a two-week period were analysed. 36 patients had documented evidence of a language barrier with 7 (19.4%) having independent professional translation. 20 (55.6%) patients had family members providing translation, for 4 patients limited English was used and previous documentation was used for 3 patients.

Cycle 2- Posters and information leaflets were disseminated regarding how to access translation services. There was no improvement in the types of translation used. Only 1 patient had impartial professional translation, out of 43 patients identified.

Cycle 3- Advocates (Bengali speaking professional translators) were made available on the ward twice a week. Results showed no significant improvement, with only 6 (10%) identified having impartial professional translation. However staff and patient feedback has been positive.

Lessons

Impartial professional translation is essential in reducing barriers and delivering equitable health care. This can be difficult to achieve in busy healthcare services. Education alone is not enough. Good accessibility to translation services is paramount in promoting usage.

Key messages

• Healthcare services often fall short of providing impartial professional translation.

• Education alone is not enough. Good accessibility to translation services is paramount in promoting usage.

Understanding clinician barriers to providing equitable healthcare for ethnic minority populations

Background

It has long been recognised that ethnic minority groups have worse health outcomes in the UK. Social determinants of health (SDH) contribute significantly to these inequalities. However, inequalities persist, even after controlling for these determinants. As well as being less likely to engage with healthcare services, ethnic minority groups are more likely to report poor experiences. The majority of healthcare in the UK is delivered through patient: clinician interactions (PCI), therefore a good working relationship with patients is paramount. Recent focus has been placed on ensuring “cultural competence”. Whilst this is important, we suggest also examining the culture within healthcare itself. Healthcare professionals are not immune to bias, preconceptions and the stresses of work and this must be taken into account. A seminal piece of work on this is the “culture of medicine” framework proposed by Boutin-Foster et al, which examines the impact of these factors.

Aims and Methodology

This paper aims to examine barriers within PCI that impact healthcare for ethnic minorities. A formal literature review was conducted and 131 relevant studies were identified. Grounded theory was used for analysis and data was categorised into themes with Boutin-Foster’s framework used as a structure.

Results

The review found that the concept of implicit bias was paramount in PCI. Three major barriers resulting from this bias are suggested: its impact on clinical decision making, the impact on clinician-patient communication and finally the resultant lack of trust in clinicians and poor perceived quality of care by ethnic minority groups.

Conclusions

Clinician implicit bias is a major barrier to equitable healthcare for ethnic minority populations. A solution we propose is to acknowledge our own preconceptions. Awareness of our own culture, preconceptions and the pressures around us will allow us to find solutions to these barriers, including further research and education.

Key messages

• Clinician implicit bias within the “Culture of Medicine” is a barrier to equitable healthcare for ethnic minority populations.

• Awareness of our own culture and preconceptions is paramount to addressing these barriers.

Pharmacist-led multidisciplinary approach in preventing strokes in people with atrial fibrillation

Background/Introduction

Targets set by Public Health England (PHE) state that 90% of patients with atrial fibrillation (AF) are expected to receive anticoagulation by 2029. In 2019/2020, across three London boroughs serving a population of 770,000, the percentage of AF patients at high risk of stroke (CHA2DS2VASc>2) anticoagulated was below the target set by PHE. In addition, optimisation of risk factors can significantly reduce the risk of cardiovascular disease and associated mortality in these patients.

Purpose

To provide specialist input from a cardiovascular pharmacist to prevent AF-related strokes through improvement of anticoagulation rates and optimisation of cardiovascular risk factors in patients with AF across three London boroughs over one year, as well as minimising bleed risk in patients on dual antithrombotic therapy.

Methods

A specialist cardiovascular pharmacist was commissioned to identify high-risk AF patients (CHA2DS2VASc>2) by working with primary care clinicians. Utilising “proactive care frameworks” created by UCLPartners and Clinical Effectiveness Group Queen Mary University of London, patients were stratified and prioritised for review. Patients not on anticoagulation were deemed to be at highest risk, requiring an urgent review to assess suitability for anticoagulation. A virtual multidisciplinary team (MDT) would review any complex patients and agree an action plan. Patients on dual antithrombotic therapy were also assessed to determine if antiplatelet therapy was indicated to minimise risk of major bleeding. All AF patients were reviewed for suitability of statin initiation to optimise cardiovascular risk prevention.

Results

At baseline, 86% (7581/8582) of AF patients with a CHA2DS2VASc>2 across the three boroughs were anticoagulated. 1001 patients were reviewed by a specialist pharmacist, with 84% (841/1001) of patients having a CHA2DS2VASc between 2–5, and 28% (280/1001) on antiplatelet monotherapy. Analysis at 12 months following intervention reported that 95% (7888/8280) of AF patients with a CHA2DS2VASc>2 were suitably anticoagulated, an improvement of 9%. 6% (61/1001) of patients were switched from antiplatelets and 25% (246/1001) were newly initiated on anticoagulation. 13% (130/1001) of patients required specialist MDT input to determine appropriateness for anticoagulation initiation. There was also a reduction in dual anticoagulation and antiplatelet therapy from 429 to 252 patients (41% reduction). Lastly of those reviewed, 2609 patients received a recommendation to start a statin for either primary (n=1981) or secondary prevention (n=628).

Conclusion(s)

Provision of a specialist cardiovascular pharmacist supported a multidisciplinary workforce to significantly improve and optimise cardiovascular risk, and reduce the risk of stroke in this high-risk population for people with AF across all three boroughs. By extrapolating these results nationally, 3600 strokes could be averted over 18 months.

Prognostic value of FFRCT in patients with stable chest pain – a 3-year follow-up of the ADVANCE-DK registry

Introduction

The short-term safety of using coronary CT angiography (CTA) derived fractional flow reserve (FFRCT) to guide downstream testing after CTA is well documented. Whether the prognostic information provided by FFRCT can be extended to sustained follow-up and to patients with a high degree of coronary artery calcification (CAC) is unknown.

Purpose

To evaluate the association between FFRCT and clinical outcomes in new onset stable symptomatic patients with coronary stenosis up to 3 years after CTA index testing.

Methods

Multicenter 3-year follow-up study of 900 patients from the Assessing Diagnostic Value of Non-invasive FFRCT in Coronary Care (ADVANCE) registry at three Danish sites, the “ADVANCE-DK Registry”. All patients had at least one ≥30% coronary stenosis by CTA and underwent subsequent core laboratory FFRCT analysis by HeartFlow. The criterium for an abnormal FFRCT test result was an FFRCT value ≤0.80 (2 cm distal to stenosis). High CAC was defined as a CAC score ≥400. The primary endpoint (PE) was a composite of all-cause death and spontaneous myocardial infarction (MI). The secondary endpoint (SE) was a composite of cardiovascular (CV) death and spontaneous MI. Events were adjudicated by an independent clinical committee.

Results

Patient characteristics are given in Table 1. Coronary stenosis ≥50% was present in 750 (83%) patients. In total 36 patients suffered a PE (all-cause death, n=24; MI, n=12) and 22 an SE (CV death, n=10; MI, n=12). An abnormal vs a normal FFRCT test result was associated with an increased risk of the PE and of the SE both overall and in patients with high CAC; PE (all), 6.6% vs 2.1%, relative risk (RR): 3.1; 95% CI: 1.6–6.3, p<0.001, SE (all), 5.0% vs 0.6%, RR: 8.7; 95% CI: non assessable, p<0.001, PE (high CAC), 9.0% vs 2.2%, RR: 4.1; 85% CI: 1.4–11.8, p=0.001, and SE (high CAC), 6.6% vs 0.5%, RR: 12.0; 95% CI: non assessable, p=0.01, respectively, Figure 1. The observed increased risk in patients with an abnormal vs a normal FFRCT test result persisted after adjustment for degree of stenosis by CCTA (< / ≥50%) and amount of CAC (< / ≥400): PE, adjusted RR: 2.5; 95% CI: 1.2–5.2, p=0.02, and SE, adjusted RR: 8.0; 95% CI: 2.1–30.2, p=0.002.

Conclusion

Patients with stable chest pain, stenosis by CTA and a normal FFRCT test result have a low risk of adverse outcomes during 3 years of follow-up. An abnormal FFRCT identifies patients at increased risk of death or spontaneous MI. These associations are consistent in patients with high levels of CAC.

FFRCT and recurrent symptoms in patients with stable chest pain

Introduction

The major benefit of coronary revascularization when compared with optimal medical treatment (OMT) in patients with stable chest pain (CP) relates to improvement of symptoms and reduction of reinterventions. Non-invasive methods are warranted to discriminate between patients at low and high risk of recurrent CP for subsequent guidance of antianginal treatment (invasive or OMT).

Purpose

To evaluate the association between coronary CT angiography (CTA) derived fractional flow reserve (FFRCT), recurrent CP and quality of life (QOL) in patients with new onset stable CP and stenosis by CTA.

Methods

Multicenter cohort 3-year follow-up sub-study of 769 patients from the Assessing Diagnostic Value of Non-invasive FFRCT in Coronary Care (ADVANCE) registry at three Danish sites, the “ADVANCE-DK Registry”. All patients had at least one ≥30% coronary stenosis by CTA and underwent subsequent core laboratory FFRCT analysis by HeartFlow. An abnormal FFRCT was defined as the lowest in vessel FFRCT value ≤0.80. Patients were classified according to completeness of revascularization by FFRCT: 1) completely revascularized (CR-FFRCT), all coronary arteries with an abnormal FFRCT test result revascularized; 2) incompletely revascularized (IR-FFRCT), ≥1 coronary artery with an abnormal FFRCT test result not revascularized. All patients completed the Seattle Angina Questionnaire (SAQ-7), the EuroQol questionnaire (EQ-5D-5L) and graded (0–100) overall health using the EQ VAS scale at 3-year follow-up. Recurrent CP was defined as CP within the last 4 weeks prior to this follow-up.

Results

Patient characteristics are given in Table 1. At follow-up 23% patients reported recurrent CP. An abnormal vs a normal FFRCT increased the risk of recurrent CP, 27% vs 15%, RR: 1.82; 95% CI: 1.31–2.52, p<0.001. Amongst patients with abnormal FFRCT, revascularization (+/−) was associated to a numerical, but not statistical significantly, reduced risk of recurrent CP, 23% vs 30%, RR: 0.76; 95% CI: 0.56–1.03, p=0.07. IR-FFRCT vs CR-FFRCT had a higher risk for recurrent CP, 31% vs 13%, RR: 2.34; 95% CI: 1.48–3.68, p<0.001, whilst no difference was observed for CR-FFRCT vs normal FFRCT, 13% vs 15%, RR: 0.92; 95% CI: 0.54–1.54, p=0.74. IR-FFRCT vs CR-FFRCT or normal FFRCT, had lower SAQ-7, EQ-5D-5L and EQ-VAS scores, Table 1, all p<0.005. Scores for three selected SAQ-7 domains are shown in Figure 1. Use of antianginal medicine was higher in IR-FFRCT compared to CR-FFRCT and normal FFRCT, mean ± SD: 1.2±0.05 vs 1.0±0.04, p=0.02.

Conclusion

An abnormal FFRCT identifies patients with an increased risk of recurrent CP up to 3 years after index testing. Completeness of revascularization by FFRCT reclassifies patients with abnormal FFRCT into groups with low and high risk for recurrent CP and impaired QOL.

Evaluation of the benefit of rivaroxaban on VOYAGER PAD primary composite of limb, heart and brain outcomes using the global rank and win ratio methods

Background/Introduction

The VOYAGER PAD trial demonstrated that rivaroxaban 2.5 mg twice daily added to background antiplatelet therapy reduced a composite of irreversible harm events of the heart limb and brain versus placebo in patients with symptomatic peripheral artery disease (PAD) after lower extremity revascularization. The primary analysis was performed as time to first event with equal weighting of components including fatal and non-fatal events.

Purpose

Traditional time to event analyses of composites generally assess outcomes with equal weights. Analyses evaluating outcomes using ranked or weighted methods may provide clinicians a mechanism to interpret results including different weighting and enable shared decision making with patients.

Methods

Exploratory analyses of the primary composite outcome were prespecified prior to trial completion/database lock. Two previously described approaches to evaluate composite outcomes by ranking or weighting were utilized. The first was the global rank method which includes ranking all components of the composite by order of clinical importance (Table 1) with a primary and alternative ranking prespecified. Each patient is assigned a rank with the worse rank for worse outcome and for patients with the same outcome, those occurring earlier assigned the worse rank. Van Elteren test for differences between groups was applied stratified by type of procedure and clopidogrel use consistent with the primary trial analysis. The second was the unmatched win ratio method according to Pocock's rule which ranked CV death higher than non-fatal events and then compared pairs of subjects, one from each treatment group for wins and losses for wins and losses as outlined in Table 1. Finkelstein and Schoenfeld statistics were utilized with confidence intervals provided from bootstrapping.

Results

A total of 6564 patients were randomized and all outcomes through the common study end date were counted. The global rank method using both the primary and alternative method yielded a statistically significant superior effect of rivaroxaban versus placebo (p-value for primary ranking 0.0158, p-value for alternative ranking 0.0155). When using the win-ratio approach, there were more wins for rivaroxaban (14.8%) than placebo (12.8%) with 72.4% of patients having no primary component events (Figure 1). The overall win ratio was 1.16 95% CI (1.03–1.30) in favor of rivaroxaban with p=0.0167.

Conclusion(s)

Rivaroxaban significantly reduces acute limb ischemia, amputation, MI, ischemic stroke or CV death in PAD after lower extremity revascularization. Exploratory analyses of this efficacy composite show consistent superiority either when considered as a ranked hierarchy of outcomes with CV death as the worst or whether considering a win-ratio approach ranking CV death as worse followed by non-fatal events. These data support the robustness of the primary trial results when considering ranking of the composite components.

Completeness of revascularization by FFRCT and prognosis in stable chest pain

Introduction

Major randomized trials of patients with stable chest pain (CP) demonstrated no prognostic benefits of coronary revascularization over optimal medical treatment (OMT). However, in a recent large-scale study, completeness of revascularization was associated with a reduced risk of all-cause death and non-fatal myocardial infarction (MI).

Purpose

To evaluate the association between completeness of revascularization relative to the result of coronary CT angiography (CTA) derived fractional flow reserve (FFRCT) and 3-year prognosis in patients with new onset stable CP and coronary stenosis.

Methods

Multicenter cohort 3-year follow-up sub-study of 900 patients from the Assessing Diagnostic Value of Non-invasive FFRCT in Coronary Care (ADVANCE) registry at three Danish sites, the “ADVANCE-DK Registry”. All patients had at least one ≥30% coronary stenosis by CTA and underwent subsequent core laboratory FFRCT analysis by HeartFlow. The FFRCT result was abnormal when ≤0.80 (2 cm distal to stenosis). Patients were classified according to completeness of revascularization by FFRCT: 1) completely revascularized (CR-FFRCT), all coronary arteries with an abnormal FFRCT test result revascularized; 2) incompletely revascularized (IR-FFRCT), ≥1 coronary artery with an abnormal FFRCT test result not revascularized. The primary endpoint (PE) was a composite of all-cause death and spontaneous MI. The secondary endpoint (SE) was a composite of cardiovascular (CV) death and spontaneous MI.

Results

Patient characteristics are given in Table 1. In total 36 (4.0%) patients suffered a PE (all-cause death, n=24; MI, n=12) and 22 (2.4%) an SE (CV death, n=10; MI, n=12). Overall, an abnormal vs a normal FFRCT test result was associated with an increased risk of both the PE, 6.6% vs 2.1%, relative risk (RR): 3.1; 95% CI: 1.6–6.3, p<0.001 and of the SE, 5.0% vs 0.6%, RR: 8.7; 95% CI: non assessable, p<0.001. In patients with abnormal FFRCT, revascularization vs no revascularization did not reduce the risk of the PE or the SE (data not shown). Patients with IR-FFRCT vs CR-FFRCT had a numerical, but not statistical significantly, increased risk of the PE, 8.6% vs 4.2%, RR: 2.14; 95% CI: 0.87–5.26, p=0.10), and an increased risk of the SE, 7.1% vs 2.4%, RR: 3.13; 95% CI: 1.02–9.63, p=0.04, Figure 1. In CR-FFRCT versus normal FFRCT no difference in the risk of the PE or the SE was observed, Figure 1. Univariate sensitivity analyses performed in the IR-FFRCT group did not reveal any differences in the risk of the PE or the SE after adjustment for neither statin therapy at follow-up (−/+), baseline risk variables (< / ≥3), amount of CAC (< / ≥400), degree of stenosis by CTA (< / ≥50%) nor referral to ICA (−/+).

Conclusion

In symptomatic patients with coronary stenosis by CTA, incomplete revascularization determined by FFRCT is associated with an increased risk of adverse cardiovascular outcomes compared to complete revascularization.
