Results of a survey of cardiovascular risk factor prevalence amongst health care workers. The Executive Committee of SHARP--(Scottish Heart and Arterial Risk Prevention).

Summary analyses of screening data were used to ascertain the cardiovascular risk profile in a sample of health care workers in Scotland. A sample of NHS staff (298 women and 78 men) were screened during visits to Perth Royal Infirmary (PRI) in 1996 and 1997. Comparisons were made within subsets and with previous screening studies. Health care workers have been a neglected component of the workforce for receiving education about risk factors. The high prevalence of smokers found in this sample should be a cause for concern.

A mobile screening unit, practicalities and problems.

The need for a mobile screening unit to travel throughout Scotland to measure and modify cardiovascular risk factors in the apparently healthy working population was fulfilled by the conversion of a double-decker bus. The aim of the project was to assess the incidence of risk factors in healthy individuals and to modify their risk factors by individual counselling. Many unforeseen practical problems were encountered and overcome during the planning stage and during the project. The team of specially trained staff spent three and a half years screening more than 20,000 people throughout Scotland. This project provides a model for other screening projects involving a multicentre/scattered cohort.

Heart and arterial disease risk factors measured in an office workforce: changes from 1993 to 1996. The Scottish Heart and Arterial Risk Prevention Group (SHARP).

Screening for cardiovascular risk factor prevalence was arranged in an office workforce in Scotland with two screenings taking place three years apart, in order to measure and attempt to modify individual risk factor profiles, and in order to explore the nature and extent of any changes. There were some increases over time for both sexes, with increased tobacco usage for men, significant increases in diastolic blood pressure for both sexes and a significant increase in mean cholesterol levels for women. A separate analysis was restricted to those individuals screened on both occasions and sought to explore the effect of personal counselling and advice: in fact there were significant increases in tobacco usage for women, with more starting smoking than stopping, and for both sexes there were significant rises in cholesterol levels and increases in body mass index for many individuals. There was significantly increased use of wine and spirits by both sexes.

Screening for risk factors for cardiovascular disease: a psychological perspective.

The success of cardiovascular disease (CVD) risk factor screening programmes depends heavily on good uptake rates and the extent of risk factors modification following screening. It is thus important to try to understand what affects people's decision to attend a screening appointment and their motivation to change their lifestyle, if necessary, following screening. This paper summarises three studies undertaken to describe uptake of screening and risk factor modification and to identify the psychological factors involved. The studies took place in two settings: a worksite mobile screening service and a city health centre screening programme. The results identified a number of sociodemographic, personal and organizational factors involved in screening behaviour which offer suggestions for effective planning of screening programmes.

Cholesterol testing by general practitioners in Grampian: patterns and outcomes.

Initiation, distribution, concomitants and follow-up of cholesterol testing were studied in Grampian. Data were examined for 4979 patients, representing all patients in one year from those general practices who made exclusive use of the clinical chemistry laboratory for cholesterol testing. A random sample of 215 patients was studied in further detail. Age and sex distribution, results of cholesterol tests and their follow-up, nature and results of associated biochemical tests, test initiation, testing rates by practice, and prescription rates of lipid lowering agents by practice were measured. Cholesterol testing was mostly in line with current knowledge of cardiovascular risk, and associated with further cardiovascular and biochemical assessment. There was a 90-fold range in practice cholesterol testing rates, and a similarly wide range in prescription rates of lipid lowering agents; there was a significant correlation between these. Rates and results of follow-up testing suggests a "rule of halves" for cholesterol testing.

General practice blood pressure recording in Scotland: variations in the classification of hypertension.

A questionnaire concerning blood pressure assessment, as part of health promotion activity, was circulated to all 770 Gpass practices in Scotland producing a 64.6% response rate. The results reveal a wide range in both the systolic and diastolic levels chosen to classify blood pressure as normal, borderline raised or raised. Practices are using a variety of values to indicate hypertension when considering systolic and, to a lesser extent, diastolic pressure. The variations found suggest that both over and under treatment are a significant risk to patients. The introduction of the 1993 health promotion regulations means that practices are required to actively target their practice population for blood pressure assessment and appropriate intervention. We suggest that this process will be enhanced if doctors are encouraged to adopt the established guidelines for the classification of blood pressure or general practice computer software is adopted to offer blood pressure protocol support.

Heart and arterial disease risk factor levels in the Scottish workforce: cross-sectional study of risk factor levels. The SHARP Committee. Scottish Heart and Arterial Disease Risk Prevention.

Between 1991-93 a specially trained team of nurses screened 19,435 subjects from various workforces in different regions of Scotland to identify cardiovascular disease risk factor levels in the Scottish working population. The regions visited provided a wide geographical spread. Name, age, occupation, social class, personal and family history of cardiovascular disease were recorded along with consumption of tobacco, alcohol and salt. Height and weight were measured and Body Mass Index (BMI) calculated; systolic (SBP) and diastolic (DBP) blood pressure, blood glucose and blood cholesterol were also measured. The proportion of social class I-IV in men studied was 49, 22, 22, and 7% respectively and in women 28, 29, 39 and 5%. Fifty two per cent of men and 61% of women had never smoked and 24% of men and 17% of women had previously stopped smoking. Twenty one per cent of both sexes were still smoking. Eighteen per cent of men drank more than 21 units of alcohol per week and 3.4% of women drank more than 14 units per week. Mean values of SBP and DBP increased with age and the percentage with hypertension (> or = 148/90 mm Hg) in men and women was 5% and 24% respectively. Mean BMI was slightly higher in men than women (25.3 & 24.5 respectively) and there was a significant (p < 0.01) rise in BMI with age in both sexes. Forty six per cent of men and 32% of women were classified as overweight (BMI > 25) while 9% of men and 9% of women were classified as obese (BMI > 30).(ABSTRACT TRUNCATED AT 250 WORDS)

Health promotion and the use of Gpass in Scotland.

OBJECTIVE: To identify how computerised practices using Gpass software (General Practice Administration System for Scotland), currently implement the new health promotion regulations. DESIGN: Postal questionnaire to all Gpass practices in Scotland. Data were gathered on types and methods of recording health promotion data, Read code selection, health education given and intended methods of data analysis. Questionnaire results were compared with data from an Electronic Questionnaire analysing actual data recorded on practice computers. RESULTS: Overall response rate: 64.6%, 94.8% of the responding practices have been approved for health promotion band three. Most practices (94.5%) use their computer for data collection, 63.6% of practices use a manual data capture form and 28.8% use computer data capture methods. Methods of collecting patient data and selection of Read codes for computer data entry are variable. Most practices use one method of data collection; a significant minority use multiple methods or more than one Read code to record the same item. The recording of health promotion on computer has increased greatly since the introduction of the new regulations: the current levels of recording are alcohol history (26.3%), blood pressure reading (57.6%), smoking (35.4%), exercise (7.1%), weight (21.4%) and height (16.4%). Most practices (94.3%) intend using Gpass for data analysis. CONCLUSION: Methods of collecting and recording health promotion data differ greatly between practices, with variable standardisation of health promotion codes and differing use of appropriate elements of the Gpass software.

Measurement and management of cardiovascular risk factors--is screening worthwhile?

Coronary heart disease has been described as Scotland's national disease and ways of reducing its incidence are therefore of paramount importance especially in younger males. A recent British Medical Journal paper has indicated that general practitioners can make little impact on patients' lifestyles. This paper shows that a cohort of Scottish men (Social Class III-V) responded well (80%) to offers of screening for risk factors of CHD, continued to attend for review and showed highly significant changes in their risk factor profiles. A committed enthusiastic primary care team have shown the potential for reducing coronary risk factors in so-called healthy men.
