General practitioners' perspectives on the prevention of cardiovascular disease: systematic review and thematic synthesis of qualitative studies

Comparison of Patients Classified as High-Risk between International Cardiovascular Disease Primary Prevention Guidelines

Background: Cardiovascular disease (CVD) primary prevention guidelines classify people at high risk and recommended for pharmacological treatment based on clinical criteria and absolute CVD risk estimation. Despite relying on similar evidence, recommendations vary between international guidelines, which may impact who is recommended to receive treatment for CVD prevention. Objective: To determine the agreement in treatment recommendations according to guidelines from Australia, England and the United States. Methods: Cross-sectional analysis of the National Health and Nutrition Examination Survey (n = 2647). Adults ≥ 40 years were classified as high-risk and recommended for treatment according to Australia, England and United States CVD prevention guidelines. Agreement in high-risk classification and recommendation for treatment was assessed by Kappa statistic. Results: Participants were middle aged, 49% were male and 38% were white. The proportion recommended for treatment was highest using the United States guidelines (n = 1318, 49.8%) followed by the English guidelines (n = 1276, 48.2%). In comparison, only 26.6% (n = 705) of participants were classified as recommended for treatment according to the Australian guidelines. There was moderate agreement in the recommendation for treatment between the English and United States guidelines (κ = 0.69 [0.64-0.74]). In comparison, agreement in recommendation for treatment was minimal between the Australian and United States guidelines (κ = 0.47 [0.43-0.52]) and weak between the Australian and English guidelines (κ = 0.50 [0.45-0.55]). Conclusions: Despite similar evidence underpinning guidelines, there is little agreement between guidelines regarding the people recommended to receive treatment for CVD prevention. These findings suggest greater consistency in high-risk classification between CVD prevention guidelines may be required.

Communicating cardiovascular risk: Systematic review of qualitative evidence

INTRODUCTION

Cardiovascular risk prediction models are widely used to help individuals understand risk and make decisions.

METHODS

Systematic review of qualitative evidence. We searched MEDLINE, Embase, PsycINFO and CINAHL. We included English-language qualitative studies on the communication of cardiovascular risk. We assessed study quality using Hawker et al.'s tool and synthesised data thematically.

RESULTS

Thirty-seven studies were included. Many patients think that risk scores are of limited practical value. Other sources of information feed into informal estimates of risk, which may lead patients to reject the results of clinical risk assessment when the two conflict. Clinicians identify a number of barriers to risk communication, including patients' limited understanding of risk and excessive anxiety. They use a range of strategies for adapting risk communication. Both clinicians and individuals express specific preferences for risk communication formats.

DISCUSSION

Ways of communicating risk that provide some comparison or reference point seem more promising. The broader context of communication around risk may be more important than the risk scoring instrument. Risk communication interventions, in practice, may be more about appeals to emotion than a rationalistic model of decision-making.

Specialty preference for cardiovascular prevention practice in the Southeast US and role of a preventive cardiologist

INTRODUCTION

Cardiovascular disease (CVD) prevention is practiced concurrently by providers from several specialties. Our goal was to understand providers' preference of specialties in CVD prevention practice and the role of preventive cardiologists.

MATERIALS AND METHODS

Between 11 October 2021 and 1 March 2022, we surveyed providers from internal medicine, family medicine, endocrinology, and cardiology specialties to examine their preference of specialties in managing various domains of CVD prevention. We examined categorical variables using Chi square test and continuous variables using t or analysis of variance test.

RESULTS

Of 956 invitees, 263 from 21 health systems and 9 states responded. Majority of respondents were women (54.5%), practicing physicians (72.5%), specializing in cardiology (43.6%), and working at academic centers (51.3%). Respondents favored all specialties to prescribe statins (43.2%), ezetimibe (37.8%), sodium-glucose cotransporter-2 (SGLT2) inhibitors (30.5%), and aspirin in primary prevention (36.3%). Only 7.9% and 9.5% selected cardiologists and preventive cardiologists, respectively, to prescribe SGLT2 inhibitors. Most preferred specialists (i.e. cardiology and endocrinology) to manage advanced lipid disorders, refractory hypertension, and premature coronary heart disease. The most common conditions selected for preventive cardiologists to manage were genetic lipid disorders (17%), cardiovascular risk assessment (15%), dyslipidemia (13%), and refractory/resistant hypertension (12%).

CONCLUSIONS

For CVD prevention practice, providers favored all specialties to manage common conditions, specialists to manage complex conditions, and preventive cardiologists to manage advanced lipid disorders. Cardiologists were least preferred to prescribe SGLT2 inhibitor. Future research should explore reasons for selected CVD prevention practice preferences to optimize care coordination and for effective use of limited expertise.

Stakeholder perceptions of preventive approaches to rheumatoid arthritis: qualitative study of healthcare professionals' perspectives on predictive and preventive strategies

BACKGROUND

There is increasing research interest in the development of preventive treatment for individuals at risk of rheumatoid arthritis (RA). Previous studies have explored the perceptions of at-risk groups and patients about predictive and preventive strategies for RA, but little is known about health care professionals' (HCPs) perspectives.

METHODS

One-to-one semi-structured qualitative interviews were conducted (face-to-face or by telephone) with HCPs. Audio recordings of the interviews were transcribed, and the data were analysed by thematic analysis.

RESULTS

Nineteen HCPs (11 female) were interviewed, including ten GPs, six rheumatologists and three rheumatology nurse specialists. The thematic analysis identified four organising themes: 1) Attributes of predictive and preventive approaches; 2) Ethical and psychological concerns; 3) Implementation issues and 4) Learning from management of other conditions. Theme 1 described necessary attributes of predictive and preventive approaches, including the type and performance of predictive tools, the need for a sound evidence base and consideration of risks and benefits associated with preventive treatment. Theme 2 described the ethical and psycho-social concerns that interviewees raised, including the potential negative economic, financial and psychological effects of risk disclosure for 'at-risk' individuals, uncertainty around the development of RA and the potential for benefit associated with the treatments being considered. Theme 3 describes the implementation issues considered, including knowledge and training needs, costs and resource implications of implementing predictive and preventive approaches, the role of different types of HCPs, guidelines and tools needed, and patient characteristics relating to the appropriateness of preventive treatments. Theme 4 describes lessons that could be learned from interviewees' experiences of prediction and prevention in other disease areas, including how preventive treatment is prescribed, existing guidelines and tools for other diseases and issues relating to risk communication.

CONCLUSIONS

For successful implementation of predictive and preventative approaches in RA, HCPs need appropriate training about use and interpretation of predictive tools, communication of results to at-risk individuals, and options for intervention. Evidence of cost-efficiency, appropriate resource allocation, adaptation of official guidelines and careful consideration of the at-risk individuals' psycho-social needs are also needed.

Clinicians' self-reported efficacy in cardiovascular prevention practice in the southeastern United States

Aim: We assessed self-reported efficacy in cardiovascular prevention practice among internal medicine, family medicine, endocrinology and cardiology clinicians. Patients & methods: We emailed a 21-item questionnaire to 956 physicians, nurse practitioners, physician assistants and pharmacists. Results: 264 clinicians responded (median age: 39 years, 55% women, 47.9% specialists). Most expressed high self-efficacy in lifestyle counselling, prescribing statins, metformin, and aspirin in primary prevention, but low self-efficacy in managing specialized conditions like elevated lipoprotein(a). Compared with specialists, PCPs expressed lower self-efficacy in managing advanced lipid disorders and higher self-efficacy in prescribing sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists. Conclusion: Self-efficacy in cardiovascular prevention varied across specialties. Future research should explore relevant provider, clinic and system level factors to optimize cardiovascular prevention.

Factors related to Japanese internal medicine doctors' retention or migration to rural areas: a nationwide retrospective cohort study

BACKGROUND

Internal medicine (IM) doctors in Japan play the role of primary care physicians; however, the shortage of rural physicians continues. This study aims to elucidate the association of age, sex, board certification, type of work, and main clinical work with the retention or migration of IM doctors to rural areas.

METHODS

This retrospective cohort study included 82,363 IM doctors in 2010, extracted from the national census data of medical doctors. The explanatory variables were age, sex, type of work, primary clinical work, and changes in board certification status. The outcome was retention or migration to rural areas. The first tertile of population density (PD) of municipalities defined as rural area. After stratifying the baseline ruralities as rural or non-rural areas, the odds ratios (ORs) of the explanatory variables were calculated using generalized estimation equations. The analyses were also performed after age stratification (<39, 40-59, ≥60 years old).

RESULTS

Among the rural areas, women had a significantly higher OR for retention, but obtaining board certification of IM subspecialties had a significantly lower OR. Among the non-rural areas, physicians who answered that their main work was IM without specific subspecialty and general had a significantly higher OR, but obtaining and maintaining board certification for IM subspecialties had a significantly lower OR for migration to rural areas. After age stratification, the higher OR of women for rural retention was significant only among those aged 40-59 years. Those aged under 40 and 40-59 years in the non-rural areas, who answered that their main work was IM without specific subspecialty had a significantly higher OR for migration to rural areas, and those aged 40-59 years in the rural areas who answered the same had a higher OR for rural retention.

CONCLUSIONS

Obtaining and maintaining board certification of IM subspecialties are possible inhibiting factors for rural work, and IM doctors whose main work involves subspecialties tend to work in non-rural areas. Once rural work begins, more middle-aged female IM doctors continued rural work compared to male doctors.

'Some of my patients only come to renew their prescriptions. They are not interested in any additional advice or support'. Physicians' perceptions on their roles in cardiovascular diseases risk reduction and management in Fiji

BACKGROUND

Primary health care (PHC) physicians' perceptions are vital to understand as they are the first-line health care providers in cardiovascular diseases (CVD) risk assessment and management. This study aims to explore PHC physicians' perceptions on their roles and their perceptions on management and risk reduction approaches on CVD risk reduction and management in Fiji.

METHODS

This is a qualitative study conducted in the Suva Medical area among 7 health centers from 1 August to 31 September, 2021. Purposive sampling was used to recruit physicians who worked in the Suva medical area as PHC physicians with at least 6 months' experience in the Special Outpatients Department clinics. In-depth interview were conducted using a semi-structured questionnaire over the telephone and recorded on a tablet device application. The interview content was then transcribed, and thematic analysis was done.

RESULTS

This study included 25 PHC physicians. From the thematic analysis, 2 major themes emerged with 6 subthemes. Theme 1 was CVD management skills with 3 subthemes including education, experience and trainings, beliefs and attitudes of physicians, self-confidence and effectiveness in CVD risk reduction and management. Theme 2 was roles and expectations with 3 subthemes including perceptions of effective treatment, perceptions of physicians' roles and perceptions of patients' expectations. Physicians generally see their role as central and imperative. They perceive to be important and leading toward combating CVDs.

CONCLUSIONS

Physicians' perceptions on their commitment to prevention and management of CVDs through their skills and knowledge, beliefs and motivation should be acknowledged. It is recommended that the physicians are updated on the current evidence-based medicine. Limitations include results that may not be the reflection of the entire physician and multidisciplinary community and the difficulties in face-to-face interviews due to the coronavirus diseases of 2019 pandemic.

Treatment and low-density lipoprotein cholesterol levels in patients with hypercholesterolaemia or mixed dyslipidaemia at high or very high cardiovascular risk: a population-based cross-sectional study in the Netherlands

OBJECTIVE

To describe treatment patterns, low-density lipoprotein cholesterol (LDL-C) levels and healthcare resource utilization (HCRU) in the Netherlands in 2018 of patients with hypercholesterolaemia or mixed dyslipidaemia at high or very high cardiovascular (CV) risk.

METHODS

From the PHARMO Database Network adult patients with a diagnosis or receiving lipid lowering therapy (LLT) between 2009 and 2018 were selected. Patients at high or very high CV risk according to 2016 ESC/EAS guidelines with recorded LDL-C levels who were treated with LLT or were characterized as statin intolerant in 2018 were included. LLT treatment patterns, LDL-C levels and HCRU (General Practitioner [GP] consultations and hospitalizations) were assessed.

RESULTS

The study population included 54,346 patients, of which 70% were at very high CV risk and 30% at high CV risk. The majority (93%) received statin monotherapy, mostly of moderate (73%) or high (15%) intensity. Only 3% received a combination of statin and ezetimibe. Statin intolerance, based on a treatment algorithm, was estimated at 3%. Average LDL-C decreased with LLT intensity. Overall, 74% reached LDL-C < 2.5 mmol/l and 34% <1.8 mmol/l with their current treatment, and 46% reached their LDL-C goal according to 2016 ESC/EAS guidelines. The highest rates of hospitalizations and GP consultations, including home visits, were recorded in patients with peripheral artery disease or polyvascular disease.

CONCLUSION

The treatment of hypercholesterolaemia and mixed dyslipidaemia in patients at high or very high CV risk in the Netherlands was suboptimal in 2018. To further lower CV risk alternative treatment strategies using add-on therapies are needed.

The Path of a Cardiac Patient-From the First Symptoms to Diagnosis to Treatment: Experiences from the Tertiary Care Center in Poland

Cardiovascular diseases (CVDs) are major concerns in the healthcare system. An individual diagnostic approach and personalized therapy are key areas of an effective therapeutic process. The major aims of this study were: (1) to assess leading patient problems related to symptoms, diagnosis, and treatment of CVDs, (2) to examine patients' opinions about the healthcare system in Poland, and (3) to provide a proposal of practical solutions. The 27-point author's questionnaire was distributed in the Cardiology Department of the Tertiary Care Centre between 2nd September-13th November 2021. A total of 132 patients were recruited, and 82 (62.12%; nmale = 37, 45.12%; nfemale = 45, 54.88%) was finally included. The most common CVDs were arrhythmias and hypertension (both n = 43, 52.44%). 23 (28.05%) patients had an online appointment. Of the patients, 66 (80.49%) positively assessed and obtained treatment, while 11 (13.41%) patients declared they received a missed therapy. The participants identified: (1) waiting time (n = 31; 37.80%), (2) diagnostic process (n = 18; 21.95%), and (3) high price with limited availability of drugs (n = 12; 14.63%) as the areas that needed the strongest improvement. Younger patients more often negatively assessed doctor visits (30-40 yr.; p = 0.02) and hospital interventions (40-50 yr.; p = 0.008). Older patients (50-60 years old) less often negatively assessed the therapeutic process (p = 0.01). The knowledge of the factors determining patient adherence to treatment and satisfaction by Medical Professionals is crucial in providing effective treatment. Areas that require the strongest improvement are: (1) waiting time for an appointment and diagnosis, (2) limited availability and price of drugs, and (3) prolonged, complicated diagnostic process. Providing practical solutions is a crucial aspect of improving CVDs therapy.

Barriers and facilitators to clinical behaviour change by primary care practitioners: a theory-informed systematic review of reviews using the Theoretical Domains Framework and Behaviour Change Wheel

BACKGROUND

Understanding the barriers and facilitators to behaviour change by primary care practitioners (PCPs) is vital to inform the design and implementation of successful Behaviour Change Interventions (BCIs), embed evidence-based medicine into routine clinical practice, and improve quality of care and population health outcomes.

METHODS

A theory-led systematic review of reviews examining barriers and facilitators to clinical behaviour change by PCPs in high-income primary care contexts using PRISMA. Embase, MEDLINE, PsychInfo, HMIC and Cochrane Library were searched. Content and framework analysis was used to map reported barriers and facilitators to the Theoretical Domains Framework (TDF) and describe emergent themes. Intervention functions and policy categories to change behaviour associated with these domains were identified using the COM-B Model and Behaviour Change Wheel (BCW).

RESULTS

Four thousand three hundred eighty-eight reviews were identified. Nineteen were included. The average quality score was 7.5/11. Reviews infrequently used theory to structure their methods or interpret their findings. Barriers and facilitators most frequently identified as important were principally related to 'Knowledge', 'Environmental context and resources' and 'Social influences' TDF domains. These fall under the 'Capability' and 'Opportunity' domains of COM-B, and are linked with interventions related to education, training, restriction, environmental restructuring and enablement. From this, three key areas for policy change include guidelines, regulation and legislation. Factors least frequently identified as important were related to 'Motivation' and other psychological aspects of 'Capability' of COM-B. Based on this, BCW intervention functions of persuasion, incentivisation, coercion and modelling may be perceived as less relevant by PCPs to change behaviour.

CONCLUSIONS

PCPs commonly perceive barriers and facilitators to behaviour change related to the 'Capability' and 'Opportunity' domains of COM-B. PCPs may lack insight into the role that 'Motivation' and aspects of psychological 'Capability' have in behaviour change and/or that research methods have been inadequate to capture their function. Future research should apply theory-based frameworks and appropriate design methods to explore these factors. With no 'one size fits all' intervention, these findings provide general, transferable insights into how to approach changing clinical behaviour by PCPs, based on their own views on the barriers and facilitators to behaviour change.

Melanoma risk assessment and management: a qualitative study among Australian general practitioners

Background

Preventive guidelines for melanoma recommend that patients at high risk of melanoma receive targeted screening; however, this requires careful selection of those at high risk. To the authors’ knowledge, there has been no previous research into how all physicians approach the selection and management of high-risk individuals. Melanoma risk-prediction models are available to assist in the identification of high-risk patients but are not routinely used clinically.

Aim

To examine how GPs assessed and managed melanoma risk, and the opportunities for using melanoma risk-prediction models in primary care.

Design and setting

Semi-structured telephone interviews were conducted with 20 Australian GPs.

Method

GPs who had completed a cross-sectional online questionnaire study on melanoma risk were purposively sampled and recruited. Semi-structured telephone interviews were conducted with Australian GPs between 9 July and 10 September 2019. Interviews were audiorecorded, professionally transcribed, and analysed using grounded theory.

Results

Melanoma risk assessment and its management can be understood as a linear workflow consisting of five clinical process domains with patient selection as the entry point. There was variation between GPs on the identification of melanoma risk factors, melanoma risk estimation, management, and patient education because of intuitive and analytical processes guiding risk assessment, and the influence of patient factors. GPs were largely receptive towards melanoma risk-prediction models, sharing facilitators for and barriers to their potential implementation.

Conclusion

Further primary care interventions sensitive to existing workflow arrangements may be required to standardise melanoma risk-assessment and management processes.

Factors related to under-treatment of secondary cardiovascular risk, including primary healthcare: Australian National Health Survey linked data analysis

OBJECTIVE

To inform national evidence gaps on cardiovascular disease (CVD) preventive medication use and factors relating to under-treatment - including primary healthcare engagement - among CVD survivors in Australia.

METHODS

Data from 884 participants with self-reported CVD from the 2014-15 National Health Survey were linked to primary care and pharmaceutical dispensing data for 2016 through the Multi-Agency Data Integration Project. Logistic regression quantified the relation of combined blood pressure- and lipid-lowering medication use to participant characteristics.

RESULTS

Overall, 94.8% had visited a general practitioner (GP) and 40.0% were on both blood pressure- and lipid-lowering medications. Medication use was least likely in: women versus men (OR=0.49[95%CI:0.37-0.65]), younger participants (e.g. 45-64y versus 65-85y: OR=0.58[0.42-0.79])and current versus never-smokers (OR=0.73[0.44-1.20]). Treatment was more likely in those with ≥9 versus ≤4 conditions (OR=2.15[1.39-3.31]), with ≥11 versus 0-2 GP visits/year (OR=2.62[1.53-4.48]) and with individual CVD risk factors (e.g. high blood pressure OR=3.13 [2.34-4.19]) versus without); the latter even accounting for GP service-use frequency.

CONCLUSIONS

Younger people, smokers, those with infrequent GP visits or without CVD risk factors were the least likely to be on medication.

IMPLICATIONS FOR PUBLIC HEALTH

Substantial under-treatment, even among those using GP services, indicates opportunities to prevent further CVD events in primary care.

Primary care costs due to prodromal Alzheimer disease: a real-world study in patients with a 10-year or longer medical history

BACKGROUND

The aim of this study was to estimate primary care costs of prodromal signs/symptoms of Alzheimer disease (AD), during a 10-year or longer period preceding AD diagnosis, in relation to costs cumulated in the general population for the same reasons.

METHODS

Nested case-control study involving 1889 AD cases and 18,890 controls aged 60+ from the Italian primary care Health Search Database (HSD). AD incident cases were through the International Classification of Diseases, 9th edition. Costs related to drugs, diagnostic tests and specialist referrals triggered by prodromal AD signs and/or symptoms were quantified and compared with costs cumulated by non-AD counterparts.

RESULTS

During the pre-diagnosis 10-year or longer period, prodromal signs and symptoms trigger diagnostic and therapeutic costs 55% higher than those cumulated in general population for the same clinical reasons. After accounting for patients' comorbidity and regional differences, the mean cost related to diagnostic and therapeutic procedures, and those related to specialist referrals, amounted to 854.1 €(SD: 630.6 €) in AD incident cases vs. 527.3 €(SD: 446.2) cumulated in patients not developing AD.

CONCLUSION

Prodromal AD manifestations are associated with primary care costs that resulted higher than those cumulated in the general population aged 60+. It remains to be elucidated if earlier dementia diagnoses would be associated with reduced costs triggered by the same clinical signs and symptoms.

Factors influencing follow-up care post-TIA and minor stroke: a qualitative study using the theoretical domains framework

Background

Follow-up care after transient ischaemic attack (TIA) and minor stroke has been found to be sub-optimal, with individuals often feeling abandoned. We aimed to explore factors influencing holistic follow-up care after TIA and minor stroke.

Methods

Qualitative semi-structured interviews with 24 healthcare providers (HCPs): 5 stroke doctors, 4 nurses, 9 allied health professionals and 6 general practitioners. Participants were recruited from three TIA clinics, seven general practices and one community care trust in the West Midlands, England. Interview transcripts were deductively coded using the Theoretical Domains Framework and themes were generated from coded data.

Results

There was no clear pathway for supporting people with TIA or minor stroke after rapid specialist review in hospital; consequently, these patients had limited access to HCPs from all settings (‘Environmental context and resources’). There was lack of understanding of potential needs post-TIA/minor stroke, in particular residual problems such as anxiety/fatigue (‘Knowledge’). Identification and management of needs was largely influenced by HCPs’ perceived role, professional training (‘Social professional role and identity’) and time constraints (‘Environmental context and resources’). Follow-up was often passive – with onerous on patients to seek support – and predominantly focused on acute medical management (‘Intentions’/‘Goal’).

Conclusions

Follow-up care post-TIA/minor stroke is currently sub-optimal. Through identifying factors which influence follow-up, we can inform guidelines and practical strategies to improve holistic healthcare.

Detection and Prediction of Incident Alzheimer Dementia over a 10-Year or Longer Medical History: A Population-Based Study in Primary Care

BACKGROUND

Despite the crucial role played by general practitioners in the identification and care of people with cognitive impairment, few data are available on how they may improve the early recognition of patients with Alzheimer dementia (AD), especially those with long (i.e., 10 years and longer) medical history.

AIMS

To investigate the occurrence and the predictors of AD during a 10-year or longer period prior AD diagnosis in primary care patients aged 60 years or older.

MATERIALS AND METHODS

A cohort study with a nested case-control analysis has been conducted. Data were extracted from the Italian Health Search Database (HSD), an Italian database with primary care data. AD cases have been defined in accordance with the International Classification of Diseases, ninth edition (ICD-9-CM) codes and coupled with the use of anti-dementia drugs. Prevalence and incidence rates of AD have been calculated. To test the association between candidate predictors, being identified in a minimum period of 10 years, and incident cases of AD, we used a multivariate conditional logistic regression model.

RESULTS

As recorded in the primary care database, AD prevalence among patients aged 60 years or older was 0.8% during 2016, reaching 2.4% among nonagenarians. Overall, 1,889 incident cases of AD have been identified, with an incidence rate as high as 0.09% person-year. Compared with 18,890 matched controls, history of hallucinations, agitation, anxiety, aberrant motor behavior, and memory deficits were positively associated with higher odds of AD (p < 0.001 for all) diagnosis. A previous diagnosis of depression and diabetes and the use of low-dose aspirin and non-steroidal anti-inflammatory drugs were associated with higher odds of AD (p < 0.05 for all).

CONCLUSION

Our findings show that, in accordance with primary care records, 1% of patients aged 60 years and older have a diagnosis of AD, with an incident AD diagnosis of 0.1% per year. AD is often under-reported in primary care settings; yet, several predictors identified in this study may support general practitioners to early identify patients at risk of AD.

Identifying enablers and barriers to referral, uptake and completion of lifestyle modification programmes: a rapid literature review

OBJECTIVE

To identify current, policy-relevant evidence about barriers and enablers associated with referral, uptake and completion of lifestyle modification programmes (LMPs) for secondary prevention of chronic disease in adults.

DESIGN

A rapid review, co-designed with policymakers, of peer-reviewed and grey literature using a modified Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework.

DATA SOURCES

Medline, Embase, Scopus, PsycINFO and CINAHL were searched for relevant studies and literature reviews. Grey literature was identified through Advanced Google searching and targeted searching of international health departments' and non-government organisations' websites.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Documents published 2010-2020, from high-income countries, reporting on programmes that included referral of adults with chronic disease to an LMP by a health professional (HP).

DATA EXTRACTION AND SYNTHESIS

Data from grey and peer-reviewed literature were extracted by two different reviewers. Extracted data were inductively coded around emergent themes. Regular meetings of the review group ensured consistency of study selection and synthesis.

RESULTS

Twenty-nine documents were included: 14 grey literature, 11 empirical studies and four literature reviews. Key barriers to HPs referring patients included inadequate HP knowledge about LMPs, perceptions of poor effectiveness of LMPs and perceptions that referral to LMPs was not part of their role. Patient barriers to uptake and completion included poor accessibility and lack of support to engage with the LMPs. Enablers to HP referral included training/education, effective interdisciplinary communication and influential programme advocates. Support to engage with LMPs after HP referral, educational resources for family members and easy accessibility were key enablers to patient engagement with LMPs.

CONCLUSIONS

Factors related to HPs' ability and willingness to make referrals are important for the implementation of LMPs, and need to be coupled with support for patients to engage with programmes after referral. These factors should be addressed when implementing LMPs to maximise their impact.

Predictors of successful weight loss outcomes amongst individuals with obesity undergoing lifestyle interventions: A systematic review

Understanding the predictors of weight loss with lifestyle interventions can help to ascertain the probable outcomes of individuals with obesity who undergo such interventions. This systematic review assessed the evidence of predictors of successful weight loss among individuals who are overweight or with obesity undergoing lifestyle interventions. Four electronic databases (PubMed, Cochrane Reviews, PsychInfo and Wiley) were searched to find relevant literature published in the past 20 years. A total of 1351 titles were identified in the initial search, of which 23 studies were finally included. Predictors were synthesized in the domains of socio-demographic factors, anthropometric parameters, psychological and behavioural factors and intervention-based factors. The overall quality of evidence on predictors was then appraised using an adapted GRADE approach. Patient-specific factors such as being male, older in age, having existing cardiometabolic comorbidities and limited fat intake were significantly associated with weight loss success. Amongst intervention specific predictors, greater initial weight loss and higher adherence to lifestyle advice were associated with greater weight loss success. In this review, initial weight loss came out to be as the most important predictor of successful weight loss outcome.

Absolute cardiovascular disease risk score and pharmacotherapy at the time of admission in patients presenting with acute coronary syndrome due to coronary artery disease in a single Australian tertiary centre: a cross-sectional study

OBJECTIVES

To describe (1) absolute cardiovascular disease risk (ACVDR) scores in patients presenting to hospital with acute coronary syndrome (ACS) and (2) proportions of these patients on guideline-recommended pharmacotherapy according to their ACVDR score.

DESIGN

Cross-sectional study.

SETTING

Single-site tertiary centre hospital, Queensland, Australia over a 12-month period.

PARTICIPANTS

Patients >18 years of age presenting to hospital with ACS due to coronary artery disease (CAD) confirmed by angiography.

PRIMARY AND SECONDARY OUTCOME MEASURES

Proportion of patients without prior history of CVD with a high ACVDR score, and of patients with a prior history of CVD, who are on guideline-recommended pharmacotherapy.

RESULTS

527 ACS patients were included of whom the mean age was 63 years and 75% were male. Overall, 66% (350) had no prior CVD and 34% (177) patients had prior CVD.In patients with no prior CVD, the proportions of patients with low, intermediate and high CVD risk scores were 41%, 24% and 36%. In the no prior CVD, high-risk patient group, 48% were on no preventative pharmacotherapy, 32% on single pharmacotherapy and 20% patients on complete guideline-recommended pharmacotherapy. In the prior CVD group, 7% patients were on no pharmacotherapy, 40% on incomplete pharmacotherapy and 53% were on complete guideline-recommended pharmacotherapy.

CONCLUSION

This study adds to the evidence on implementation gaps in guideline-recommended management of ACVDR, showing that a large proportion of patients presenting with ACS due to CAD were at high risk of developing CVD prior to the event and most were not on guideline-recommended treatment. A significant proportion of these events are likely to have been preventable, and therefore, increased assessment and appropriate treatment of ACVDR in primary care is needed to reduce the incidence of CVD events in the population.

Integrated cardiovascular risk management programme versus usual care in patients at high cardiovascular risk: an observational study in general practice

BACKGROUND

Cardiovascular diseases (CVDs) are the leading cause of death worldwide. Despite the impact of CVDs, risk factors are often insufficiently controlled in patients at high risk. Recently, integrated multidisciplinary cardiovascular risk management (CVRM) programmes have been introduced in primary care.

AIM

To investigate the effects of a CVRM programme on systolic blood pressure (SBP) and low-density lipoprotein (LDL)-cholesterol.

DESIGN & SETTING

A prospective observational study was undertaken in patients at high cardiovascular (CV) risk who were aged 40-80 years. Integrated CVRM care was compared with usual care in general practice in the Netherlands.

METHOD

Intervention and usual care patients were matched at baseline on age, sex, and presence of CVD. During 1 year of follow-up, patients received integrated or usual CVRM care in general practice. Primary outcomes were SBP and LDL-cholesterol. Secondary outcomes included calculated 10-year CV risk, body mass index (BMI), lifestyle (smoking, physical activity, and dietary habits), medication use, patient satisfaction, healthcare consumption, morbidity, comorbidity, and mortality. Mixed-model analyses were used to assess the outcomes.

RESULTS

Totals of 372 and 317 patients were included in the intervention and usual care group, respectively. Mean age at baseline was 65.1 years and 66.2 years, respectively, and 42% were female in both groups. After 1 year, no differences were observed in: SBP (137.2 mmHg versus 139.0 mmHg in the intervention and usual care group, respectively); LDL-cholesterol (2.6 mmol/l in both groups); or in any of the secondary outcomes.

CONCLUSION

Integrated CVRM care in general practice did not lead to a lower SBP or LDL-cholesterol in patients at high CV risk. Further research is needed to improve CVRM.

Patients' and health professionals' attitudes and perceptions towards the initiation of preventive drugs for primary prevention of cardiovascular disease: a systematic review of qualitative studies

Background

Statins and antihypertensive agents are recommended for primary prevention of cardiovascular disease (CVD), but they are not always prescribed to eligible patients.

Design & setting

A systematic review of qualitative studies.

Aim

To explore health professionals’ and patients’ attitudes towards cardiovascular preventive drugs.

Method

MEDLINE, Embase, PsychINFO, CINAHL, ASSIA, HMIC, Conference Proceedings Citation Index, and Open Grey were searched for studies of qualitative design without restrictions on date or language. Two reviewers performed study selection, data extraction, quality assessment, and thematic synthesis.

Results

In total, 2585 titles and abstracts were screened, yielding 27 studies, of which five met eligibility criteria on full text assessment. These included 62 patients and 47 health professionals. Five themes emerged about patient attitudes: questioning preventive drugs; perceived benefit and risks, such as improving quality of life; patient preferences; trust in health professional judgement; and family, friends, and media influences. Five themes emerged about health professional attitudes: addressing patient concerns and information; duty as a health professional to prescribe; uncertainty about preventive drug prescribing; recognising consequences of prescribing, such as unnecessary medicalisation; and personalised treatment.

Conclusion

The attitudes of patients and health professionals regarding drug initiation for primary prevention reflect the complexity of the patient–health professional encounter in primary practice. For prescribing to be more adherent to guidelines, research should further investigate the patient–health professional relationship and the appropriate communication methods required when discussing drug initiation, specifically for primary prevention.

Cross-sectional survey describing general practitioners' absolute cardiovascular disease risk assessment practices and their relationship to knowledge, attitudes and beliefs about cardiovascular disease risk in Queensland, Australia

OBJECTIVES

To describe general practitioners' (GPs') absolute cardiovascular disease risk (ACVDR) self-reported assessment practices and their relationship to knowledge, attitudes and beliefs about ACVDR.

DESIGN

Cross-sectional survey with opportunistic sampling (October-December 2017).

SETTING

Sunshine Coast region, Queensland, Australia.

PARTICIPANTS

111 GPs responded to the survey.

PRIMARY AND SECONDARY OUTCOME MEASURES

Proportion of GPs reporting a high (≥80%) versus moderate (60%-79%)/low (<60%) percentage of eligible patients receiving ACVDR assessment; proportion agreeing with statements pertaining to knowledge, attitudes and beliefs about ACVDR and associations between these factors.

RESULTS

Of the 111 respondents, 78% reported using the Australian ACVDR calculator; 45% reported high, 25% moderate and 30% low ACVDR assessment rates; >85% reported knowing how to use ACVDR assessment tools, believed assessment valuable and were comfortable with providing guideline-recommended treatment. Around half believed patients understood the concept of high risk and were willing to adopt recommendations. High assessment rates (vs moderate/low) were less likely among older GPs (≥45 vs ≤34 years, age-adjusted and sex-adjusted OR (aOR) 0.36, 95% CI 0.12 to 0.97). Those who answered knowledge-based questions about the guidelines incorrectly had lower assessment rates, including those who answered questions on patient eligibility (aOR 0.13, 95% CI 0.02 to 1.11). A high assessment rate was more likely among GPs who believed there was sufficient time to do the assessment (aOR 3.79, 95% CI 1.23 to 11.61) and that their patients were willing to undertake lifestyle modification (aOR 2.29, 95% CI 1.02 to 5.15). Over 75% of GPs agreed better patient education, nurse-led assessment and computer-reminder prompts would enable higher assessment rates.

CONCLUSIONS

Although the majority of GPs report using the ACVDR calculator when undertaking a CVD risk assessment, there is a need to increase the actual proportion of eligible patients undergoing ACVDR assessment. This may be achieved by improving GP assessment practices such as GP and patient knowledge of CVD risk, providing sufficient time and nurse-led assessment.

[Blood flow restriction training for people with cardiovascular disease: An exploratory review]

OBJECTIVE

To analyse the evidence on the effects of blood flow restriction training in people with cardiovascular disease.

MATERIALS AND METHODS

We searched MEDLINE, EMBASE, SPORTDiscus, CINAHL, LILACS, SCOPUS and Wiley databases. Experimental and non-experimental studies investigating the effects of blood flow restriction in participants with cardiovascular disease were included.

RESULTS

Six clinical trials and three non-experimental studies met the inclusion criteria. The experimental studies were conducted in participants with hypertension and ischaemic heart disease. Non-experimental studies described hemodynamic adaptations and potential adverse effects of therapy. The risk of bias of the included clinical trials was moderate to high. Exercise-induced hemodynamic stress increased significantly during training with blood flow restriction compared with traditional training. The small number of available studies have focused mostly on acute effects, but chronic effects are unknown.

CONCLUSION

There is currently no evidence to recommend the use of blood flow restriction in people with cardiovascular disease.
