GP's adherence to guidelines for cardiovascular disease among elderly: a quality development study

Appropriateness of prescribing profiles and intake adherence to non-vitamin K antagonist oral anticoagulants in patients with atrial fibrillation: analysis of a retrospective longitudinal study using real-world data from Northern Portugal (AF-React Study)

OBJECTIVES

This study aimed to assess the appropriateness of prescribing profiles and intake adherence to non-vitamin K antagonist oral anticoagulants (NOACs) in patients with atrial fibrillation (AF).

DESIGN

Retrospective longitudinal study.

SETTING

The study was conducted in the Regional Health Administration of Northern Portugal.

PARTICIPANTS

The authors selected a database of 21 854 patients with prescriptions for NOACs between January 2016 and December 2018 and were classified with AF until December 2018.

OUTCOME MEASURES

The appropriate dosage of NOAC for patients with AF divided into three categories: contraindicated, inconsistent and consistent, based on the 2020 European Society of Cardiology guidelines for AF.

RESULTS

Dabigatran had a lower percentage of guideline-consistent doses (n=1657, 50.1%) than other drugs such as rivaroxaban (n=4737, 81.6%), apixaban (n=3830, 78.7%) and edoxaban (n=436, 82.1%). Most patients with an inconsistent dose were prescribed a lower dose than recommended based on their glomerular filtration rate (GFR). Among patients younger than 75 years with GFR >60 mL/min, 59.8% (n=10 028) had an adequate GFR range, while 27.8% (n=7166) of GFR measurements from patients older than 75 years old and 29.4% (n=913) of GFR measurements from patients younger than 75 years with GFR <60 mL/min were within an adequate time range. Adherence to NOACs varied across different drugs, with 59.1% (n=540) adhering to edoxaban, 56.3% (n=5443) to rivaroxaban, 55.3% (n=3143) to dabigatran and 53.3% (n=4211) to apixaban.

CONCLUSIONS

Dabigatran had the lowest percentage of guideline-consistent doses. Patients younger than 75 years with GFR >60 mL/min had the highest percentage with an adequate GFR range, while other groups who require closer GFR monitoring had lower percentages within an adequate GFR range. Adherence to NOACs differed among different drugs, with greater adherence to treatment with edoxaban and less adherence to apixaban.

Effects of lipid-lowering treatment intensity and adherence on cardiovascular outcomes in patients with a recent myocardial infarction: a Swedish register-based study

BACKGROUND

Oral lipid-lowering treatment (LLT) is the standard of care for patients with cardiovascular disease (CVD). However, insufficient treatment intensity and poor adherence can lead to suboptimal treatment benefit, rendering patients at increased risk of CVD.

AIMS

The objective of this study was to evaluate trends in LLT intensity and adherence in Sweden over time, and their association with major adverse cardiovascular events (MACE) after recent myocardial infarction (MI), and also to assess the impact of transition from secondary to primary care on intensity and adherence.

METHODS AND RESULTS

This retrospective observational cohort study used data from Swedish nationwide patient registers and included patients on LLT after an MI in the years 2010-2016 (n = 50,298; mean age, 68 years; 69% men). LLT intensity was evaluated over time (overall, for 2010-2013 and for 2014-2016) as the proportion of patients prescribed low-, moderate-, and high-intensity LLT. Adherence was assessed as the proportion of days covered. A combined measure of intensity and adherence was also considered. Differences in treatment patterns and MACE were assessed. Initiation of high-intensity LLT increased over the two time periods studied (2010-2013, 32%; 2014-2016, 91%). Adherence varied by LLT intensity and was highest in patients receiving high-intensity LLT (>80%), especially during the first time period. Little change in treatment intensity or the combined measure of intensity and adherence was observed after transition to primary care. There was a significant association between the combined measure of intensity and adherence and MACE reduction (hazard ratio [95% confidence interval] per 10% increase in the combined measure: 0.84 [0.82-0.86]; P < 0.01).

CONCLUSION

The proportion of post-MI patients with high LLT intensity and adherence has increased in recent years, with little change after transfer from specialist to primary care. The combination of LLT intensity and adherence is important for preventing future cardiovascular events.

Strategies for improving guideline adherence of anticoagulants for patients with atrial fibrillation in primary healthcare: A systematic review

BACKGROUND

Clinical guidelines on atrial fibrillation management help optimize the use of oral anticoagulants. However, guideline non-adherence is common, particularly in the primary care setting. The primary aim of this systematic review was to identify effective strategies for improving adherence to guideline-directed thromboprophylaxis to patients with atrial fibrillation in the primary care setting.

METHODS

A search was conducted on 6 electronic databases (Medline, Embase, ScienceDirect, Scopus, the Cumulative Indexing of Nursing and Allied Health Literature, and Web of Science) supplemented by a Google advanced search. Studies aimed at improving oral thromboprophylaxis guideline adherence in patients with atrial fibrillation, in the primary care setting, were included in the study.

RESULTS

A total of 33 studies were included in this review. Nine studies employed electronic decision support (EDS), of which 4 reported modest improvements in guideline adherence. Five of 6 studies that utilized local guidelines as quality improvement measures reported improvement in guideline adherence. All 5 studies that employed coordinated care and the use of specialist support and 4 of the 5 studies that involved pharmacist-led interventions reported improvements in guideline adherence. Interventions based mainly on feedback from audits were less effective.

CONCLUSIONS

Multifaceted interventions, especially those incorporating coordinated care and specialist support, pharmacists, or local adaptations to and implementation of national and/or international guidelines appear to be more consistently effective in improving guideline adherence in the primary care setting than interventions based mainly on EDS and feedback from audits.

Quality improvement in chronic care by self-audit, benchmarking and networking in general practices in South Tyrol, Italy: results from an interventional study

BACKGROUND

Systematic strategies promoting quality of care in general practice are yet under-represented in several European countries.

OBJECTIVE

This interventional study assessed whether a combined intervention (self-audit, benchmarking, quality circles) improved quality of care in Salzburg, Austria and South Tyrol, Italy. The present publication reports the Italian results.

METHODS

We developed quality indicators for general practice in a consensus process based on pre-existing quality programmes. The indicators addressed diagnosis and treatment regarding eight common chronic conditions. A quality score comprising 91 indicators was calculated (0-5 points per indicator depending on fulfilment, maximum 455 points). We collected anonymous data from the electronic health records of the participating physicians in 2012, 2013 and 2014. Wilcoxon signed-rank tests were used for pre-post analysis.

RESULTS

Thirty-six GPs participated in the study. The median quality score increased significantly from 177.0 points at baseline to 272.0 points at the second follow-up (P = 0.000). Improvements concerned process and intermediate outcome indicators particularly between baseline and the first follow-up.

CONCLUSION

Performance was relatively low at baseline and improved considerably, mainly in the first study period. The intervention investigated in this study can serve as a model for future quality programmes. A customized electronic health record for the implementation of this intervention as well as standardized and consistent documentation by GPs is a prerequisite. Use of a limited set of quality indicators (QIs) and regular QI modification is probably advisable to increase the benefits. Long-term prospective studies should investigate the impact of QI-based interventions on end-result outcomes.

Status of evidence-based chronic diseases prevention implementation in Shanghai, China: A qualitative study

BACKGROUND

Given the rapid increase in chronic disease epidemics in developing countries and the lagging research and practice in evidence-based chronic diseases prevention (EBCDP), we evaluated the status of public health practitioners' implementation of EBCDP and its impeding factors in China, as well as made a comparison between China and the developed countries to encourage better utilisation of this new field of science in China.

METHODS

We interviewed health practitioners and patients from various health institutions in China and conducted a literature review to assess the current status of EBCDP practice in developed countries and identify the contextual driving factors.

RESULTS

China is in its initial stage of EBCDP practice, as it lacks evidence-based interventions. Moreover, health practitioners' awareness of EBCDP is inadequate. The lack of policy support, especially funding, has restricted the efficiency and quality of EBCDP in terms of its adoption, implementation, and maintenance. Currently, EBCDP practice is limited to the practitioners' spontaneous behaviours. The literature review showed that developed countries practising EBCDP did well in evidence development and awareness; however, much has yet to be explored regarding practitioners' adoption and implementation and the maintenance of evidence-based practice. The impeding factors in developed countries were related to individual (patients and physicians) and organisational factors (such as resources, leaders, and climate).

CONCLUSION

To promote EBCDP practice in China, more evidence for effective chronic disease prevention programmes is needed, and multiple and flexible measures should be implemented for a successful transition to evidence-based practice.

The adoption of hypertension reference framework: An investigation among primary care physicians of Hong Kong

Background

The Hong Kong Government released a Reference Framework (RF-HT) for Hypertension Care for Adults in Primary Care Settings since 2010. No studies have evaluated its adoption by primary care physicians (PCPs) since its release.

Aim

We aimed to evaluate the level of PCPs’ adoption of the RF-HT and the potential barriers of its use in family practice.

Design and setting

A cross-sectional study was conducted by a self-administered validated survey among all PCPs in Hong Kong through various means.

Methods

We assessed the level of and factors associated with its adoption by multivariate logistic regression modelling.

Result

A total of 3,857 invitation episodes were sent to 2,297 PCPs in 2014–2015. We received 383 completed questionnaires. The average score of adoption was 3.43 out of 4.00, and 47.5% of PCPs highly adopted RF-HT in their daily consultations. Male practitioners (adjusted odds ratio [aOR] = 0.524, 95% CI = 0.290–0.948, p = 0.033) and PCPs of public sector (aOR = 0.524, 95% CI = 0.292–0.940, p = 0.030) were significantly less likely to adopt the RF-HT. PCPs with higher training completion or being academic fellow are more likely to adopt RF-HT than those who were “nil to basic training completion” (aOR = 0.479, 95% CI = 0.269–0.853, p = 0.012) or “higher trainee” (aOR = 0.302, 95% CI = 0.093–0.979, p = 0.046). Three most-supported suggestions on RF-HT improvement were simplification of RF-HT, provision of pocket version and promoting in patients.

Conclusion

Among PCP respondents, the adoption level of the RF-HT was high. These findings also highlighted some factors associated with its adoption that could inform targeted interventions for enhancing its use in clinical practice.

Improving quality of care in general practices by self-audit, benchmarking and quality circles

Guideline adherence of general practitioners (GP) regarding treatment of chronic conditions shows room for improvement. Thus, concepts have to be designed to promote quality of care. The aim of the interventional study “Improvement of Quality by Benchmarking” was to assess whether quality can be improved by self-auditing, benchmarking and quality circles in Salzburg (Austria) and South Tyrol (Italy). In this publication we present the Austrian results. Quality indicators were developed in a consensus process for eight chronic diseases based on pre-existing quality management systems. A quality score consisting of 35 indicators was calculated (0–5 points per indicator depending on fulfilment, maximum 175 points). Data were extracted from the electronic health records of participating practices in 2012, 2013 and 2014. A statistical pre-post analysis was performed using Wilcoxon signed-rank tests. A total of 20 GPs participated in the project. The mean quality score increased from 62.0 at baseline to 84.0 at the second follow-up (p = 0.003). Regarding the individual quality indicators, strong improvements were achieved between baseline and first follow-up, especially in process indicators concerning documentation. Between the first and second follow-up, quality remained in most cases at the same level. The validity of results is limited because of structural and technical problems. Due to the uncontrolled pre-post design we cannot exclude external influences on the results. Nevertheless, the intervention was able to improve measured quality of care. Barriers were detected that should be considered in a possible implementation of quality control programs.

Adherence to guidelines and mortality in atrial fibrillation

OBJECTIVE

Determining the adherence to ACC/AHA/ESC 2006 guidelines and its influence on the survival of patients with atrial fibrillation.

METHODS

Prospective observational study of patients discharged during 2007 from an Internal Medicine department with a main or secondary diagnose of atrial fibrillation. The stroke risk was estimated with the CHADS2 score. The follow-up was carried out in outpatient medical office or via telephone.

RESULTS

We included 259 patients (mean age 80.9 years); 73% of them had a high risk of stroke. Oral anticoagulants were administered to 134 (51.7%), and antiplatelet drugs to 71 (27%) patients. A rate control strategy was chosen for 155 (59.8%) patients and a rhythm control one for 28 (10.8%). In 100 (38.6%) patients, treatment was adherent to the guidelines. Adherence to the guidelines was associated with age (0.95 95%CI 0.92-0.99; p=0.03), contraindication to the use of oral anticoagulants (0.38 95%CI 0.18-0.81; p=0.01) and mitral valve heart disease/valvular prosthesis (2.10 95%CI 1.04-4.25; p=0.04). The median follow-up was 727 days, and 191 patients died. Patients treated according to the guidelines had a higher rate of survival during the first three years (0.47 vs. 0.36; p=0.049). The use of oral anticoagulants was associated with a higher probability of survival over a 5 year period (0.34 vs 0.21; p=0.001) and the rate control strategy during the first year (0.69 vs 0.57; p=0.04).

CONCLUSIONS

In the real world, the treatment of atrial fibrillation according to the guidelines is associated with improved survival for up to three years during follow-up.

Atrial fibrillation anticoagulation care in a large urban family medicine practice

OBJECTIVE

To determine the proportion of patients with atrial fibrillation (AF) in primary care achieving guideline-concordant stroke prevention treatment based on both the previous (2010) and the updated (2012) Canadian guideline recommendations.

DESIGN

Retrospective chart review.

PARTICIPANTS

Primary care patients (N = 204) with AF. The mean age was 71.3 years and 53.4% were women.

SETTING

Large urban community family practice in Toronto, Ont.

MAIN OUTCOME MEASURES

Patient demographic characteristics such as sex and age; a list of current cardiac medications including anticoagulants and antiplatelets; the total number of medications; relevant current and past medical history including presence of diabetes, stroke or transient ischemic attack, hypertension, and vascular disease; number of visits to the family physician and cardiologist in the past year and past 5 years, and how many of these were for AF; the number of visits to the emergency department or hospitalizations for AF, congestive heart failure, or stroke; if patients were taking warfarin, how often their international normalized ratios were recorded, and how many times they were in the reference range; CHADS2 (congestive heart failure, hypertension, age ≥ 75, diabetes mellitus, and stroke or transient ischemic attack) score, if recorded; and reason for not taking oral anticoagulants when they should have been, if recorded.

RESULTS

Among those who had CHADS2 scores of 0, 64 patients (97.0%) were receiving appropriate stroke prevention in AF (SPAF) treatment according to the 2010 guidelines. When the 2012 guidelines were applied, 39 patients (59.1%) were receiving appropriate SPAF treatment (P < .001). For those with CHADS2 scores of 1, 88.4% of patients had appropriate SPAF treatment according to the 2010 guidelines, but only 55.1% were adequately treated according to the 2012 guidelines (P < .001). Of the patients at the highest risk (CHADS2 score > 1), 68.1% were adequately treated with anticoagulation and an additional 8.7% (6 of 69) had documented reasons why they were not taking anticoagulants.

CONCLUSION

When assessed using the 2012 Canadian Cardiovascular Society AF guidelines, the proportion of patients receiving appropriate SPAF therapy in this primary care setting decreased substantially. All patients with CHADS2 scores of 0 or 1 should be reassessed to ensure that they are receiving optimal stroke prevention treatment.
