Abstract
Background Monitoring lifestyle or behavioural risk factors using quality indicators is critical for the primary prevention of cardiovascular disease (CVD).
Aim To summarise indicators for monitoring lifestyle risk factors for the primary prevention of CVD.
Design & setting A systematic review of quality indicators in primary care.
Method Four research databases (Ovid MEDLINE, Ovid Embase, CINAHL Plus, and Scopus) and grey literature were searched to identify articles (indicator sets) used to monitor lifestyle risk factors. Articles were assessed for methodological quality using the Appraisal of Indicators through Research and Evaluation (AIRE) instrument. Articles with strong methodological quality, scoring ≥50% in each domain (that is, relevance, stakeholder involvement, scientific evidence, and usage) were included. Indicators were categorised into assessment of lifestyle risk factors or advice on healthy lifestyle.
Results We identified 39/282 (14%) articles including indicators to monitor lifestyle risk factors from a full-text review. Of these, 19 (49%) articles with strong methodological quality, comprising 90 unique indicators, were included. Most of the indicators were on assessing smoking status (21%), body weight (18%), advice on smoking cessation (13%), immunisation (9%), and advice on physical activity (8%). Assessment of alcohol consumption (3%) and healthy eating (2%) were the least reported. When comparing assessment versus advice indicators, we found gaps in monitoring smoking status (41% assessment versus 27% advice) and body weight (35% versus 14%). Notably, there were more indicators for advice on (16%) than assessment of (4%) healthy eating.
Conclusion We identified several indicators for the monitoring of lifestyle risk factors. However, there is a need to ensure an appropriate mix of indicators on assessment versus advice.
How this fits in
Monitoring lifestyle or behavioural risk factors using quality indicators is critical for the primary prevention of cardiovascular disease. This study identified a large number of quality indicators (n = 90 extracted from 19 articles) for the assessment of lifestyle risk factors and advice on healthy lifestyle. However, there is a need for an appropriate balance of assessment of lifestyle risk factors, followed by healthy advice-related quality indicators. These indicators need to be harmonised to ensure methodological and country contextual fitness.
Introduction
Cardiovascular diseases (CVDs), including heart disease and stroke, are a leading cause of death and disability worldwide, resulting in significant costs to the health system and overall economy.1 With the current burden of CVD, global medical costs for CVD management are projected to exceed $1 trillion per year by 2030.2 Therefore, primary prevention of CVD is a critical public health priority.
Lifestyle management is an effective strategy and is considered a first-line recommendation in clinical practice guidelines for the primary prevention of CVD.3–5 Lifestyle management involves monitoring of lifestyle risk factors (for example, assessment of smoking status) and adherence to a healthy lifestyle (for example, smoking cessation) in primary care.5,6 Adopting a healthy lifestyle reduces the need for use of prevention medications.5,7 Primary care providers are typically encouraged to document process of care including a patient’s clinical profile (for example, blood pressure and smoking status) or prescription of medication to demonstrate that they adhere to clinical practice guidelines.7,8
Quality indicators (described as indicators hereafter) are tools used to assess the effectiveness of primary care.9 In the context of primary prevention, these indicators (for example, number of patients with smoking status recorded) typically include a numerator (for example, assessment of current smoking status) and denominator (for example, number of patients) to define a performance standard based on local clinical practice guidelines.10,11 These indicators should be relevant, validated, and feasible for timely monitoring of lifestyle risk factors.10,11 Therefore, there is a need to understand the current monitoring status of processes of care for lifestyle risk factors using indicators for the primary prevention of CVD.12 In this review, we aimed to identify and summarise quality indicators being used for monitoring lifestyle risk factors for the primary prevention of CVD.
Method
Study design, search strategy, and selection criteria
A systematic review was undertaken to identify articles in which lifestyle management indicators for the primary prevention of CVD were reported. This review is part of a larger systematic review registered in the International Prospective Register of Systematic Reviews (PROSPERO ID number: CRD42022359131). The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines.13 Electronic databases were searched to identify journal articles, including Ovid MEDLINE, Ovid Embase, CINAHL Plus, and Scopus. Google and Google Scholar were used to search for grey literature. The search strategy was limited to CVD or stroke or transient ischaemic attack, risk factors, primary prevention, and primary care settings (clinical practice, family practice, or general practice). Search terms included 'cardiovascular disease', 'stroke', 'quality indicators', 'primary prevention', 'primary care', or 'risk factors' (see Supplementary Table S1). These search terms were mapped into the Medical Subject Headings (MeSH), and wildcards (for example, # and $) or truncations (for example, *) were used as appropriate. Articles or grey literature published from January 2010–August 2022 were included in this review. Additional searches and grey literature from countries with similar primary care systems, such as the UK, Australia, and Canada, were updated in October 2023.
Inclusion and exclusion criteria
We included quality indicator sets reported in articles published in the English language. We focused on indicators related to assessment of lifestyle risk factors or advice on healthy lifestyle in primary care settings from all regions of the world. Articles that did not focus on the primary prevention of CVD or primary care were excluded. Editorials, research letters, case reports, opinion pieces, comments, viewpoints, correspondences, and consensus documents were excluded.
Article screening
Unique articles (excluding duplicates from EndNote [version 19]) were imported into Covidence for title and abstract screening.14 KB, MFK, and MTO screened the titles and abstracts of articles for eligibility, followed by full-text screening, referring to inclusion and exclusion criteria for selecting articles. DAC resolved conflicts between any two authors.
Data extraction
We extracted data on country, conditions, domains (assessment, advice, or education),15 numerator, denominator, and the frequency of monitoring for each quality indicator set (see Supplementary Table S2). Data extraction was undertaken by KB and reviewed by MTO and BL, and MFK or DAC resolved any disagreements.
Methodological assessment of quality indicator sets
Eligible articles were further assessed for methodological quality using the Appraisal of Indicators through Research and Evaluation (AIRE) tool. The AIRE tool comprises the following four domains: a) purpose, relevance, and organisational context; b) stakeholder involvement; c) scientific evidence; and d) additional evidence, formulation, and usage. Each item in the domains was scored on a four-point Likert scale. Standardised scores were calculated, ranging from 0%–100%, with ≥50% representing a strong methodological quality indicator set. This criterion was based on earlier reviews reporting on the appraisal of quality indicators.16,17 Articles including indicators set with weak methodological quality were excluded (Figure 1 and Supplementary Figure S1).
Data analysis and visualisation
Descriptive statistics (frequencies and percentages) were used to summarise the indicators. Pivot tables and heat maps in Microsoft Excel were used for data analysis and visualisation.
Results
Our search of research databases (n = 2207) and grey literature (n = 134) yielded 2341 articles. Of these, 282 (12.0%) full-text articles including indicators on the monitoring of lifestyle risk factors were reviewed. Indicators on lifestyle management were reported in 39 (13.8%) articles. Of which, 19 (48.7%) articles with strong methodological quality were included in this review (Figure 1, Table 1).15,18–35 Overall, 90 quality indicators were extracted from these 19 articles. These indicators were unique to the country, populations at risk of CVD (categorised based on risk scoring or assessment of multiple risk factors), or disease conditions (for example, hypertension and diabetes). Forty-six indicators (51.1%) were on assessment of lifestyle risk factors,15,18–20,22–30,33–35 while 44 (48.9%) were on advice on healthy lifestyle.15,18,19,21–28,30–32,34,35
The majority of these indicators were reported in high-income countries, mainly from Canada (26.7%; two articles)18,19 and Slovenia (20.0%; one article).15 A few indicators were reported from Tajikistan (2.2%; one article)20 and Switzerland (1.1%; one article).21 Around 16% of indicators were collected from two cross-sectional surveys in Europe.22,35 The quality indicators identified, with detailed descriptions of their numerators and denominators by domains and disease conditions or risk factors, are presented in Table 2. Overall, 47.8% (n = 43/90) of all the indicators identified did not have any specific recommendation on the reporting frequency as a part of their definition (see Supplementary Table S2).15,18–20,24,26,28,29,33,35
Summary of indicators on monitoring of lifestyle risk factors
Overall, one in five indicators reported were on assessment of smoking status (n = 19/90; 21.1%),15,18,20,22–25,27–30,33–35 followed by body weight (n = 16; 17.8%),15,18,19,22–25,35 advice on smoking cessation (n = 12; 13.3%),15,18,19,22,27,28,30,34,35 immunisation uptake (n = 8; 8.9%),15,23,24,28,32 healthy eating (n = 7; 7.8%),15,19,22,35 physical activity (n = 7; 7.8%),15,19,22,25,35 and assessment of physical activity (n = 6; 6.7%).15,19,22,25,35 Indicators on assessment of healthy eating (n = 2; 2.2%)15,19,22,35 and alcohol consumption (n = 3; 3.3%)15,19 were the least reported. Most of the indicators related to the assessment of lifestyle risk factors were on the assessment of smoking (n = 19/46; 41.3%),15,18–20,22–29,33,34 followed by body weight (n = 16; 34.8%).15,18,19,22–25,35 There were very few indicators related to assessment of alcohol consumption (n = 3; 6.5%)19,23,29 or healthy eating (n = 2; 4.3%).19 Indicators related to advice on healthy lifestyle were often smoking cessation (n = 12/44; 27.3%),15,18,19,22,27,28,30,34,35 advice on or uptake of immunisation (n = 8; 18.2%),21,23,24,26,28,31,32 physical activity (n = 7; 15.9%),15,19,22,25,35 or healthy eating (n = 7; 15.9%).15,19,22,35 Few articles included indicators for advice related to reduction of alcohol consumption (n = 3; 6.8%)15,19 or management of multiple risk factors (n = 1; 2.3%).9
A comparison between the assessment of lifestyle risk factors versus advice on healthy lifestyle demonstrated gaps in monitoring lifestyle risk factors. There were more assessment-related indicators than advice-related ones for smoking (n = 19/46 [41.3%] assessment versus n = 12/44 [27.3%] advice) and body weight (n = 16/46 [34.8%] versus n = 6/44 [13.6%]). Interestingly, there were more indicators for advice on healthy eating (n = 7/44; 15.9%) than for assessing it (n = 2/46; 4.3%) (Figure 2).
Quality indicators by the existing risk status or disease conditions
Half (n = 46/90; 51.1%) of the quality indicators identified were developed for populations at risk of CVD (categorised based on risk scoring or assessment of multiple risk factors),15,19,22,25,28,35 followed by those with existing disease condition(s) (n = 24; 26.7%),15,18–26,28,31,32,35 and those with no existing risk factor (n = 20; 22.2%).15,18,21,23,26–31,35 Indicators on lifestyle assessment or advice for people with specific conditions or risk factors were largely reported for diabetes (n = 9; 10.0%),15,21,23,24,26,28,31,32 followed by hypertension (n = 8; 8.9%)15,20,24,25,31,34 or obesity (n = 2; 2.2%).15,19 (Table 3). Indicators on the assessment of body weight were often monitored in people at risk of CVD (43.8%).15,18,19,22–25,35 Quality indicators for the assessment of body weight for those with hypertension or obesity were lacking.
Fifty per cent of indicators on physical activity were focused on populations at risk of CVD,15,19,22,25,35 with no specific reference to people with diabetes or obesity. Indicators on alcohol consumption were lacking for those with existing conditions, such as hypertension, diabetes, and obesity. The majority of advice on healthy lifestyle management indicators was lacking for those with obesity, no existing risk factors, and smokers. Advice on alcohol consumption was reported only for those at risk of CVD. Notably, advice on or uptake of influenza immunisation was largely reported for patients with diabetes for the primary prevention of CVD (Table 3).
Discussion
Summary
In this review, we identified and summarised indicators being used for monitoring lifestyle risk factors around the world, developed through a strong methodological quality to enable easy adaptation within the country context. Smoking, body weight, and physical activity were the most frequently reported, with over half of the indicators addressing these lifestyle risk factors. Indicators related to healthy eating and alcohol consumption were the least frequently reported. There were gaps in assessment of lifestyle risk factors versus advice on healthy lifestyle for smoking, body weight, and healthy eating. Additionally, we found that nearly half of the indicators lacked specific frequency for the monitoring of lifestyle risk factors.
Strengths and limitations
To the best of our knowledge, this is the first review focusing on monitoring of indicators on lifestyle management for the primary prevention of CVD in primary care. The indicators identified in this review will enable greater adoption and standardisation for monitoring of lifestyle risk factors in primary care. However, it is essential to acknowledge the limitations of this review. First, given that this review was limited to articles or literature with strong methodological quality, there is a possibility of missing relevant indicators reported in articles or literature with lower methodological quality. Second, focusing only on articles or literature published in the English language means that we may have missed some indicators from non-English speaking countries. This review may not be fully applicable to non-English-speaking contexts, emphasising the critical need for future review to be more inclusive and representative of diverse populations.
Comparison with existing literature
Contemporary clinical practice guidelines strongly recommend adopting a healthy lifestyle as a first-line recommendation for the primary prevention of CVD.36–40 However, we found that monitoring and reporting of lifestyle risk factors using indicators is sub-optimal, predominantly focused on smoking status with limited emphasis on other important risk factors, such as physical inactivity, unhealthy diet, or alcohol consumption. These gaps could be owing to the lack of a clear mandate or guideline on the assessment or advice on healthy lifestyle, the lack of a field to record lifestyle risk factors in electronic health records, or the lack of incentives for assessing lifestyle risk factors in primary care and documenting their management.35,41–46
Studies have reported that intensive behavioural or lifestyle counselling improves health outcomes (for example, reduction in blood cholesterol or systolic blood pressure) among those with established cardiovascular risk factors.47 However, in our review, indicators of advice on healthy lifestyle were minimal for patients with existing risk factors such as hypertension or diabetes. Less reporting could be owing to the lack of indicators or advice provided as part of general counselling. Therefore, it is crucial to monitor and report advice on healthy lifestyle in primary care records to improve counselling on healthy lifestyle. Usually, cardiometabolic risk factors or medication prescriptions are well documented, and a similar approach is needed for documenting lifestyle risk factor advice.43,45
We found gaps when comparing the assessment of lifestyle risk factors versus advice on healthy lifestyle. There were more assessment indicators than advice-related indicators for smoking and body weight. Studies from Australia,8,43 the US,44 and the UK42,45 highlighted the importance of monitoring and prioritising advice on healthy lifestyle (for example, physical activity) for behaviour change. Therefore, lifestyle risk factors need to be monitored with an appropriate balance of assessment and advice-related indicators in primary care.
Data on lifestyle risk factors are collected mainly through population-based surveys or as part of lifestyle intervention studies for research or population-level monitoring purposes.43–46 Therefore, there is a need for real-time data on monitoring of lifestyle risk factors at the individual level to track their behaviours, follow-up with tailored messages, and ultimately sustain their behaviour change. Real-time data on monitoring and reporting lifestyle risk factors could be improved through a multidisciplinary approach, involving professionals such as nurses, dietitians, and psychologists to enhance lifestyle management monitoring, promoting a holistic and patient-centred approach.48
Implications for research and practice
These strong methodological quality measurable indicators can be customised and adapted according to country-specific clinical practice guidelines, considering socioeconomic and cultural context, comorbidities, and at-risk populations.49 There is a need to develop indicators with an appropriate mix of assessment (for example, assessment of physical activity) and advice (for example, advice on physical activity) indicators among individuals with specific risk or disease conditions such as obesity, current smokers, chronic kidney disease, hypertension, and diabetes.
We found that nearly half of the indicators lacked information on the frequency of monitoring as a part of their indicator definition. It is essential to standardise these indicators with a defined frequency of monitoring (for example, every visit, weekly, or monthly) so the quality of lifestyle management in primary care can be tracked at a patient level. Including lifestyle indicators for both assessment and advice will enable routine monitoring of the effectiveness of lifestyle interventions over time.
In conclusion, we summarised quality indicators on assessment and advice for lifestyle management in primary care with strong methodological quality. These indicators can inform the standardisation and contextualisation for routine monitoring of lifestyle risk factors across countries. There is a need to have a balanced mix of assessment and advice-related indicators for comprehensive tracking of lifestyle risk factors. Future research should focus on validating, adapting, or tailoring these indicators to individual country’s context.12
