Managing established coronary heart disease

A Pilot Study Using a Newly Devised Manual in a Programme of Education and Support for Patients Waiting for Coronary Artery bypass Surgery

Background: Cardiac rehabilitation programmes are widely accepted as being of benefit to patients with cardiac disease. The time spent waiting for cardiac surgery can be extremely stressful but can be used to address risk factors and provide information to reduce anxiety and prepare the patient for surgery. Aims: To pilot the usefulness of a manual for pre-operative cardiac surgical patients, and assess the feasibility and usefulness to both nurses and patients of a monthly education and support programme for patients waiting for cardiac surgery. Methods: A pilot study of 42 patients followed up for 3 months. Research tools included patient questionnaires and telephone interviews, risk factor measurements and nurse focus groups. Results: Nurses and patients evaluated the manual and overall programme favourably, although the nurses found it was very labour intensive. Changes to risk factors made during the study were small but patients valued the opportunity to raise questions which fell into the categories of medical concerns, hospital procedure and risk factors. Conclusion: The manual is a useful tool for patients waiting for cardiac surgery. The programme is useful and feasible but could be targeted more specifically to patients with raised risk factors.

Primary care in Switzerland: evolution of physicians' profile and activities in twenty years (1993-2012)

Background

According to the Organization for Economic Cooperation and Development, the Swiss healthcare system is one of the most effective in the world. Yet, as other occidental countries, it has to face the increase of chronic diseases frequency and its resulting cost, particularly for primary care (PC). However very few consistent data are available to describe PC features and its evolution over time. The aim of this study is to describe the evolution of the Swiss PC physicians’ (PCPs) profile and activities between 1993 and 2012.

Methods

The date come from two independent European surveys carried out in Switzerland respectively in 1993 and 2012. Both surveys were cross-sectional ones and based on representative samples of 200 PCPs, interviewed by questionnaire.

Results

In 20 years, PCPs became older (median age 46 vs 56, p < 0.001) and more feminized (7 % vs 22 %, p < 0.001). Nowadays, they more often work in group practices (28 % vs 52 % in 2012, p < 0.001) and are more involved in other paid activities (28 % vs 66 % in 2012, p < 0.001). All the PCPs have a computer in 2012 (78 % in 1993, p < 0.001) and it is mostly used for keeping records of consultations (47 %). The number of daily face-to-face contacts with patients decreased from 31 to 24 but the average length rose from 15 to 20 min (p < 0.001). PCPs provide fewer pediatric and gynecological services but their activity remains globally unchanged in other domains. The frequency of meetings with other disciplines decreased significantly (e.g. once/month face-to-face meets with ambulatory specialists: 78 % vs 23 % in 2012, p < 0.001). The involvement of PCPs in follow-up and treatment of chronic disease globally little differed. In 2012, 8.5 % of the PCPs never performed any chirurgical acts (vs 0 % in 1993, p < 0.001).

Conclusion

This study showed a substantial evolution of Swiss PC over the last twenty years in terms of socio-demographic, organizational and service provided. The main changes include: feminization and ageing, lower diversity in services provided, fewer but longer consultations. These changes may have important implications for patients’ management and will need to be considered for health planning purposes.

Professional perspectives on a feasibility study of GP-pharmacist collaboration in the management of angina

Objective

To report the views and experiences of a convenience sample of community pharmacists and general practitioners (GPs) who participated in a five-month feasibility study exploring the ways in which community pharmacists could contribute to the management of patients with stable angina when working in partnership with GPs.

Method

Five pharmacists delivered a specified model of care, which represented one component of a district-wide strategy aimed at improving the management of ischaemic heart disease (IHD), to 208 patients in eight general practices. The care involved six evidence-based interventions: smoking cessation, dietary advice, exercise, aspirin, beta-blockers and statins. This paper illuminates professional perspectives concerning involvement in the study. The findings of semi-structured interviews exploring views and experiences of the pharmacists during the first and the final month of the study and those of the GPs at completion of the study are reported.

Setting

St Helens and Knowsley, UK, an area with a high IHD standardised mortality rate (SMR).

Key findings

The pharmacists reported high levels of satisfaction and success in relation to the study interventions and more professionally satisfying relationships with patients and GPs. Successes with therapeutic interventions were described, both within and external to the study protocol. The GPs expressed a high level of satisfaction with the conduct and outcome of the pharmacist delivered care and heightened awareness of the need to review their approach to preventive care for IHD patients.

Conclusion

The findings confirm that pharmacists and GPs can work in partnership to deliver a specified model of care to patients with stable IHD and also inform the debate on a role for community pharmacists as dependent prescribers.

Service organisation for the secondary prevention of ischaemic heart disease in primary care

BACKGROUND

Ischaemic heart disease (IHD) is a major cause of mortality and morbidity and its prevalence is set to increase. Secondary prevention aims to prevent subsequent acute events in people with established IHD. While the benefits of individual medical and lifestyle interventions is established, the effectiveness of interventions which seek to improve the way secondary preventive care is delivered in primary care or community settings is less so.

OBJECTIVES

To assess the effectiveness of service organisation interventions, identifying which types and elements of service change are associated with most improvement in clinician and patient adherence to secondary prevention recommendations relating to risk factor levels and monitoring (blood pressure, cholesterol and lifestyle factors such as diet, exercise, smoking and obesity) and appropriate prophylactic medication.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2007, Issue 4), MEDLINE (1966 to Feb 2008), EMBASE (1980 to Feb 2008), and CINAHL (1981 to Feb 2008). Bibliographies were checked. No language restrictions were applied.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials of service organisation interventions in primary care or community settings in populations with established IHD.

DATA COLLECTION AND ANALYSIS

Analyses were conducted according to Cochrane recommendations and Odds Ratios (with 95% confidence intervals) reported for dichotomous outcomes, mean differences (with 95% CIs) for continuous outcomes.

MAIN RESULTS

Eleven studies involving 12,074 people with IHD were included. Increased proportions of patients with total cholesterol levels within recommended levels at 12 months, OR 1.90 (1.04 to 3.48), were associated with interventions that included regular planned appointments, patient education and structured monitoring of medication and risk factors, but significant heterogeneity was apparent. Results relating to blood pressure within target levels bordered on statistical significance. There were no significant effects of interventions on mean blood pressure or cholesterol levels, prescribing, smoking status or body mass index. Few data were available on the effect on diet. There was some suggestion of a "ceiling effect" whereby interventions have a diminishing beneficial effect once certain levels of risk factor management are reached.

AUTHORS' CONCLUSIONS

There is weak evidence that regular planned recall of patients for appointments, structured monitoring of risk factors and prescribing, and education for patients can be effective in increasing the proportions of patients within target levels for cholesterol control and blood pressure. Further research in this area would benefit from greater standardisation of the outcomes measured.

Running nurse-led secondary prevention clinics for coronary heart disease in primary care: qualitative study of health professionals' perspectives

BACKGROUND

A randomised trial of nurse-led secondary prevention clinics for coronary heart disease resulted in improved secondary prevention and significantly lowered all-cause mortality at 4-year follow-up. This qualitative trial was conducted to explore the experience of health professionals that had been involved in running the clinics.

AIM

To identify the barriers and facilitators to establishing secondary prevention clinics for coronary heart disease within primary care.

DESIGN OF STUDY

Semi-structured audiotaped telephone interviews with GPs and nurses involved in running clinics.

SETTING

A stratified, random sample of 19 urban, suburban, and rural general practices in north-east Scotland.

METHOD

Semi-structured telephone interviews with 19 GPs and 17 practice-based nurses involved in running nurse-led clinics for the secondary prevention of coronary heart disease.

RESULTS

Eight practices had run clinics continuously and 11 had stopped, with eight subsequently restarting. Participants accounted for these patterns by referring to advantages and disadvantages of the clinics in four areas: patient care, development of nursing skills, team working, and infrastructure. Most practitioners perceived benefits for patients from attending secondary prevention clinics, but some, from small rural practices, thought they were unnecessary. The extended role for nurses was welcomed, but was dependent on motivated staff, appropriate training and support. Clinics relied on, and could enhance, team working, however, some doctors were wary of delegating. With regard to infrastructure, staff shortages (especially nurses) and accommodation were as problematic as lack of funds.

CONCLUSIONS

Nurse-led secondary prevention clinics were viewed positively by most healthcare professionals that had been involved in running them, but barriers to their implementation had led most to stop running them at some point. Lack of space and staff shortages are likely to remain ongoing problems, but improvements in funding training and communication within practices could help clinics to be put into practice and sustained.

Practice nurses' intentions to use clinical guidelines

BACKGROUND

Evidence indicates that, although nurses are increasingly using clinical guidelines to ensure higher quality of care, there is a wide variance in their adherence to them. The utility of the Theory of Planned Behaviour (TPB) has not been previously investigated in explaining this variance in community nursing.

AIM

This paper reports a study whose primary aim was to examine the utility of the TPB in explaining variations in practice nurses' intentions to offer smoking cessation advice in accordance with coronary heart disease guidelines.

METHODS

A cross-sectional survey using a postal questionnaire was carried out. A 52-item questionnaire was administered to 48 practice nurses in England. The questionnaire was designed to assess the components of the TPB, and included measures of intentions to offer smoking cessation advice, self-reported past behaviour, attitudes, subjective norms, perceived behavioural controls (PBCs), behavioural beliefs and evaluations, normative beliefs and motivation to comply, and control beliefs and evaluations.

RESULTS

The TPB explained up to 40% of variance in intentions to offer smoking cessation advice. Attitudes and PBCs were the most important predictors of intention. Among other elements of the TPB, indirect attitudes and indirect PBCs made significant positive contributions to explaining variance in intention.

DISCUSSION

Future trials of interventions to increase practice nurses' adherence to clinical guidelines could attempt to address the elements identified in this study as important factors. Further studies are required to examine the utility of the TPB in predicting practice nurses' behaviour.

Effect of a comprehensive intervention program targeting general practice staff on quality of life in patients at high cardiovascular risk: a randomized controlled trial

BACKGROUND

We implemented a comprehensive intervention program targeting general practice staff, that proved successful in optimizing practice organization and clinical decision-making. In this paper, health-related quality of life (HRQL) is investigated as a clinical outcome.

OBJECTIVE

To evaluate the effect of the implementation of an intervention program on the HRQL in patients at high cardiovascular risk.

RESEARCH DESIGN

Randomized controlled trial. Intervention practices (n = 62) received a comprehensive intervention program (by means of outreach visitors) lasting 21 months. HRQL of patients at high cardiovascular risk was assessed by the MOS 36-Item Short-Form Health Survey (SF-36), at baseline and after intervention. Three patient categories were distinguished: diabetes mellitus, cardiovascular disease and hypertension.

RESULTS

HRQL deteriorated in all respondents, but more pronounced in the control group. In diabetes patients the differences between intervention and control group were significant for the Vitality and Mental Health scales, with mean difference in change of 3.93 (95% CI: 1.08-6.78) and 3.71 (95% CI: 0.73-6.68), respectively. Patients with cardiovascular disease had significantly different changes on three scales: physical functioning (3.57, 95% CI: 0.71-6.43), vitality (3.01, 95% CI: 0.72-5.30) and social functioning (3.96, 95% CI: 0.50-7.42). In patients with hypertension, there were no differences between the intervention and control group.

CONCLUSION

Our comprehensive intervention program resulted in changes in HRQL on several domains, particularly in patients with diabetes and cardiovascular disease.

Improving access to cardiac rehabilitation for remote Indigenous clients

OBJECTIVE

To identify barriers to Indigenous patients taking up a rural general practice-based cardiac rehabilitation program. We investigated the accessibility and appropriateness of the program and the role of Indigenous health workers (IHWs) in caring for Indigenous cardiac patients.

METHODS

A cross-sectional survey of knowledge and views relating to cardiac rehabilitation was undertaken with 47 Indigenous cardiac patients and 41 health professionals in remote Queensland.

RESULTS

Only three patients were fully engaged in the program. Reasons for non-participation included: lack of knowledge about rehabilitation, low income, and having a large extended family. Although the program incorporated a training component for IHWs covering prevention and follow-up, most did not monitor patients specifically for their heart problems and thought they did not have adequate skills. Shared care was occurring in some settings but without the participation of IHWs.

CONCLUSIONS

There was general agreement that IHWs do have a role in cardiac rehabilitation. There is a need for ongoing in-service education or inclusion in training programs. Lack of understanding of the role of IHWs is a barrier to shared care. Cardiovascular disease needs to be addressed as part of the raft of chronic illnesses.

IMPLICATIONS

Training about chronic illnesses and their management needs to be linked to structural adaptations in the delivery of health services to allow efficient use of each professional's skills. Clear role delineation needs to be negotiated to allow all health professionals to carry out their job effectively.

Secondary prevention for coronary heart disease: a qualitative study

The many responsibilities of primary care, cardiac rehabilitation and secondary prevention of coronary heart disease is a growing concern. Demanding standards have been given to primary care in the National Service Framework for Coronary Heart Disease. This article reports an evaluation of an intervention to support primary care service providers in this responsibility. A part-time specialist nurse and a part-time exercise worker were appointed to work in a group of 11 GP practices in a primary care trust in a city in the north of England. The evaluation component reported here is a qualitative study of the perceptions of health professionals on secondary prevention of coronary heart disease. Interviews were conducted with 18 primary care staff from practices in both intervention (n = 11) and control (n = 11) groups. The evaluation revealed support for the development of nurse-led clinics, increased confidence and skills development among practice nurses, but some concern about competing demands on practice nurses' time. Primary healthcare professionals found their resources stretched by competing demands on their time from government initiatives.

Experience of cardiac rehabilitation after coronary artery surgery: effects on health and risk factors

OBJECTIVE

Cardiac rehabilitation (CR) programs are provided to support the recovery process following acute myocardial infarction and coronary artery bypass grafting (CABG). Attendance varies. We related attendance following CABG to severity of cardiac symptoms, general health status (Short Form-36) and prevalence of modifiable coronary artery disease (CAD) risk factors.

METHODS

209 patients due to undergo CABG were recruited and assessed preoperatively as well as at a mean of 16.4 months postoperatively. General health status was measured using the Short Form-36 questionnaire. Severity of cardiac symptoms was assessed on a visual analogue scale. Modifiable coronary artery disease risk factors (smoking, body mass index, hypertension and elevated cholesterol) and social deprivation index were noted.

RESULTS

There were ten early and three late deaths. Thirteen patients withdrew consent for investigation, therefore 183 were fully studied. Of these 65.0% completed a CR programme and 24.6% did not attend any programme; 10.4% partially completed (less than 50% of time) and were excluded from analysis. Nonattenders were more likely to be smokers (P=0.002), diabetic (P=0.028) and were more from socially deprived geographical areas (P=0.013), but the proportion of patients with BMI>25, BP>140/90 or cholesterol >5.0 mmol l(-1) were the same. There were no differences in age, preoperative NYHA score, number of grafts, angina recurrence (46 vs. 38%, P=0.35) or breathlessness (62 vs. 69%, P=0.40) between attenders and nonattenders. The severity scores of angina (2.7 vs. 3.2, P=0.286) and breathlessness (3.5 vs. 3.6; P=0.79) were no different. However, four of the eight health domains measured showed significantly better values for attenders than nonattenders; namely: general health (60 vs. 46%, P=0.001), physical function (64 vs. 51% P=0.01), role limitation physical (48 vs. 29%; P=0.02) and social function 74 vs. 62%, P=0.04).

CONCLUSIONS

This is the first report using SF 36 to evaluate benefits from attending CR. Higher general health scores (SF-36) were associated with attendance at CR although CAD risk factors and cardiac symptoms were not improved but this may be due to the long interval between assessments.

Improving quality of organizing cardiovascular preventive care in general practice by outreach visitors: a randomized controlled trial

BACKGROUND

Adequate care for patients with cardiovascular risks requires an adequate practice organization. Educational outreach visits are a promising approach to modifying professional behavior. We aimed to assess whether the quality of cardiovascular preventive care in general practice can be improved through a comprehensive intervention implemented by an educational outreach visitor.

METHODS

After baseline measurements, general practices (n = 124) in the southern half of The Netherlands were randomly allocated to either intervention or control group. The intervention, based on the educational outreach model, comprised 15 practice visits over a period of 21 months and addressed a large number of issues around task delegation, availability of instruments and patient leaflets, record-keeping, and follow-up routines. Twenty-one months after the start of the intervention, postintervention measurements were performed. The difference between ideal and actual practice in each aspect of organizing preventive care was defined as a deficiency score. Primary outcome measure was the difference in deficiency scores before and after the intervention.

RESULTS

All practices completed both baseline and postintervention measurements. The difference in change between intervention and control group adjusted for baseline was statistically significant (P < 0.001) for each aspect of organizing preventive care. The largest absolute improvement was found for the number of preventive tasks performed by the practice assistant.

CONCLUSIONS

This study showed that a comprehensive intervention implemented by outreach visitors was effective in improving organization of cardiovascular preventive care in general practice.

Nurse led shared care for patients on the waiting list for coronary artery bypass surgery: a randomised controlled trial

OBJECTIVE

To evaluate the effectiveness of a nurse led shared care programme to improve coronary heart disease risk factor levels and general health status and to reduce anxiety and depression in patients awaiting coronary artery bypass grafting (CABG).

DESIGN

Randomised controlled trial.

SETTING

Community, January 1997 to March 1998.

STUDY GROUPS

98 (75 male) consecutive patients were recruited to the study within one month of joining the waiting list for elective CABG at Glasgow Royal Infirmary University NHS Trust. Patients were randomly assigned to usual care (control; n = 49) or a nurse led intervention programme (n = 49).

INTERVENTION

A shared care programme consisting of health education and motivational interviews, according to individual need, was carried out monthly. Care was provided in the patients' own homes by the community based cardiac liaison nurse alternating with the general practice nurse at the practice clinic.

OUTCOME MEASURES

Smoking status, obesity, physical activity, anxiety and depression, general health status, and proportion of patients exceeding target values for blood pressure, plasma cholesterol, and alcohol intake.

RESULTS

Compared with patients who received usual care, those participating in the nurse led programme were more likely to stop smoking (25% v 2%, p = 0.001) and to reduce obesity (body mass index > 30 kg/m(2)) (16.3% v 8.1%, p = 0.01). Target systolic blood pressure improved by 19.8% compared with a 10.7% decrease in the control group (p = 0.001) and target diastolic blood pressure improved by 21.5% compared with 10.2% in the control group (p = 0.000). However, there was no significant difference between groups in the proportion of patients with cholesterol concentrations exceeding target values. There was a significant improvement in general health status scores across all eight domains of the 36 item short form health survey with changes in difference in mean scores between the groups ranging from 8.1 (p = 0.005) to 36.1 (p < 0.000). Levels of anxiety and depression improved (p < 0.000) and there was improvement in time spent being physically active (p < 0.000).

CONCLUSIONS

This nurse led shared care intervention was shown to be effective for improving care for patients on the waiting list for CABG.

Patients' understandings of heart attack: implications for prevention of recurrence

Patients' willingness to undertake secondary preventive strategies following heart attack are likely to be affected by their understandings of their condition. This qualitative study explored patients' understandings of heart attack in order to contribute to the design of effective secondary prevention services. In-depth interviews were conducted with 25 patients with myocardial infarction (MI). These data indicate that information received from health professionals encourages patients to view heart attack as an acute event rather than a symptom of a chronic condition and that this understanding provides patients with low motivation for long-term lifestyle change. Patients may benefit from understanding a heart attack as an acute symptom of an underlying disease process which long-term medication and behavioural change can help to check. In order to achieve this, health professionals need to examine patients' understandings of their heart attack and recovery and to provide information about lifestyle which engages with these understandings.

Patients' and practice nurses' perceptions of secondary preventive care for established ischaemic heart disease: a qualitative study

A significant proportion of patients with established ischaemic heart disease remain unrecognized in general practice and those who are receiving treatment are experiencing sub-optimal care. The provision of coronary prevention by practice nurses may be an important strategy to improve the quality of this care, and this is feasible and effective. This study explored what occurred during patients' initial assessment for secondary prevention of ischaemic heart disease with a practice nurse and investigated patients' and practice nurses' views ofnurse-led clinics in primary care. Nurses were effective in history taking and offering reassurance and dietary advice, yet were less confident in discussing patients' understandings of heart disease and related medication. Practice nurse-led coronary preventive care is acceptable to both nurses and patients. Further practice nurse education is required in heart disease, cardiac medications and skills necessary for exploring and challenging patients' understandings of these issues.

The cost-effectiveness of lipid lowering in patients with ischaemic heart disease: an intervention and evaluation in primary care

BACKGROUND

There has been a major revolution in the recommended treatment of hyperlipidaemia in patients with ischaemic heart disease following the publication of the Scandinavian Simvastatin Survival Study. This was the first major study to demonstrate that lipid-lowering drugs reduced mortality and morbidity in patients with ischaemic heart disease.

AIM

To evaluate the feasibility and cost-effectiveness of screening and treating hyperlipidaemia in patients with ischaemic heart disease in primary care.

METHOD

A study conducted in a rural dispensing training practice on the border of Nottinghamshire and Lincolnshire involving 327 patients with ischaemic heart disease who were registered with the practice on 1 January 1996.

RESULTS

Eighty per cent of patients with ischaemic heart disease were considered eligible for screening and 80% of those attended for screening. The majority of patients who were screened had hyperlipidaemia that persisted after dietary advice. Despite lipid-lowering drugs, few patients had serum lipid concentrations in the target range at the end of six months. The costs of identifying and treating 83 patients with lipid-lowering drugs over five years is estimated at 105,318 Pounds at 1996 prices, or 94,257 Pounds assuming a 6% discount rate per annum. Two-thirds of this is owing to the cost of lipid-lowering drugs. The discounted cost per coronary event prevented would be 17,138 Pounds (95% CI = 12,568 Pounds-26,183 Pounds). The discounted cost per coronary death prevented would be 32,502 Pounds (95% CI = 23,564 Pounds-55,445 Pounds). There were no important adverse effects of lipid-lowering drugs on quality of life or mood.

CONCLUSION

Such a programme is feasible and acceptable within primary care, although the ongoing cost implications need to be considered against the costs and benefits of other interventions.

The therapeutic gap--compliance with medication and guidelines

Hospitals, clinics and cardiologists have a significant impact on prescribing in general practice. Physicians in primary care rank hospital recommendations as one of the most important sources of information on new drugs. However, recent surveys of coronary heart disease (CHD) prevention paint a depressing picture about the current evidence-based management of risk factors, such as hypercholesterolaemia and hypertension, in both secondary- and primary-care settings. European guidelines have identified secondary prevention as the top priority in patients with established CHD and lowered cholesterol thresholds in light of evidence, not only from the 4S study, but also from the CARE and LIPID studies, which highlighted the risks posed by even normal or moderately elevated cholesterol levels. There is a clear need for those involved in quality assurance in hospital care to take ownership of such guidelines. Cardiologists can play a key role - they do not face the problem alone, but evidence suggests that they can have a significant positive impact on the management of CHD risk factors in primary care.

The success of an integrated care programme for patients with ischaemic heart disease: the practice nurses' perspective of SHIP

Follow-up care of patients with angina and myocardial infarction after hospital discharge is known to be suboptimal across the UK. The employment of cardiac liaison nurses ensured timely notification of hospital discharge and good communication of each patient's current and planned care. The direct ongoing support of the liaison nurse was valued by more practice nurses than educational support meetings and the initial counselling skills course. The most important factor which enabled practice nurses to expand their role to provide post-hospital follow-up care was the support of the doctors in the practice. After the conclusion of the Southampton Heart Integrated Care Project (SHIP) and the withdrawal of cardiac liaison nurses, the lack of hospital discharge notification was the most important reason for practice nurses discontinuing follow-up care.

Patient outcome as a selection criterion in determining treatment mode

The climate of health care reform encourages scrutiny of traditional and new forms of medical and surgical therapy. With the emergence of technologically innovative cardiac procedures, therapy advocates must weigh cost versus patient outcomes. Therapies range from purely medical management, through staged interventions, to median sternotomy and cardiopulmonary bypass. Outcomes will necessarily be related to quality of life. A literature search was performed to determine types of medical and surgical therapies associated with patient outcomes as they define quality of life. Medical treatment may include the use of anti-platelet therapy, beta-blockers and diuretics to treat the cardiac patient at low risk who can maintain an acceptable quality of life. Improvements in medical therapies may extend the life of the low-risk patient, eliminating the need to consider bypass surgery. Some patients at high risk, or with left ventricular hypertrophy combined with an impaired ejection fraction, may require coronary artery bypass surgery. Studies indicate that patients undergoing open heart surgery demonstrate significant improvement in functional classification, increased activity and reduction in anti-anginal medications. Proponents of minimally invasive surgery claim potential benefits of lower surgical trauma, shorter hospital stays and shorter recovery times. Quality of life is defined by outcomes. Only by comparing outcomes of all available therapies can a physician or patient make an informed decision regarding treatment.

Randomised controlled trial of follow up care in general practice of patients with myocardial infarction and angina: final results of the Southampton heart integrated care project (SHIP). The SHIP Collaborative Group

OBJECTIVE

To assess the effectiveness of a programme to coordinate and support follow up care in general practice after a hospital diagnosis of myocardial infarction or angina.

DESIGN

Randomised controlled trial; stratified random allocation of practices to intervention and control groups.

SETTING

All 67 practices in Southampton and south west Hampshire, England.

SUBJECTS

597 adult patients (422 with myocardial infarction and 175 with a new diagnosis of angina) who were recruited during hospital admission or attendance at a chest pain clinic between April 1995 and September 1996.

INTERVENTION

Programme to coordinate preventive care led by specialist liaison nurses which sought to improve communication between hospital and general practice and to encourage general practice nurses to provide structured follow up.

MAIN OUTCOME MEASURES

Serum total cholesterol concentration, blood pressure, distance walked in 6 minutes, confirmed smoking cessation, and body mass index measured at 1 year follow up.

RESULTS

Of 559 surviving patients at 1 year, 502 (90%) were followed up. There was no significant difference between the intervention and control groups in smoking (cotinine validated quit rate 19% v 20%), lipid concentrations (serum total cholesterol 5.80 v 5.93 mmol/l), blood pressure (diastolic pressure 84 v 85 mm Hg), or fitness (distance walked in 6 minutes 443 v 433 m). Body mass index was slightly lower in the intervention group (27.4 v 28.2; P=0.08).

CONCLUSIONS

Although the programme was effective in promoting follow up in general practice, it did not improve health outcome. Simply coordinating and supporting existing NHS care is insufficient. Ischaemic heart disease is a chronic condition which requires the same systematic approach to secondary prevention applied in other chronic conditions such as diabetes mellitus.

Secondary prevention in coronary heart disease: a randomised trial of nurse led clinics in primary care

OBJECTIVE

To evaluate whether nurse run clinics in general practice improve secondary prevention in patients with coronary heart disease.

DESIGN

Randomised controlled trial.

SETTING

A random sample of 19 general practices in northeast Scotland.

PATIENTS

1173 patients (685 men and 488 women) under 80 years with working diagnoses of coronary heart disease, but without terminal illness or dementia and not housebound.

INTERVENTION

Nurse run clinics promoted medical and lifestyle aspects of secondary prevention and offered regular follow up.

MAIN OUTCOME MEASURES

Components of secondary prevention assessed at baseline and one year were: aspirin use; blood pressure management; lipid management; physical activity; dietary fat; and smoking status. A cumulative score was generated by counting the number of appropriate components of secondary prevention for each patient.

RESULTS

There were significant improvements in aspirin management (odds ratio 3.22, 95% confidence interval 2.15 to 4.80), blood pressure management (5.32, 3.01 to 9.41), lipid management (3.19, 2.39 to 4.26), physical activity (1.67, 1.23 to 2.26) and diet (1.47, 1.10 to 1.96). There was no effect on smoking cessation (0.78, 0.47 to 1.28). Of six possible components of secondary prevention, the baseline mean was 3.27. The adjusted mean improvement attributable to intervention was 0.55 of a component (0.44 to 0.67). Improvement was found regardless of practice baseline performance.

CONCLUSIONS

Nurse run clinics proved practical to implement in general practice and effectively increased secondary prevention in coronary heart disease. Most patients gained at least one effective component of secondary prevention and, for them, future cardiovascular events and mortality could be reduced by up to a third.

Secondary prevention in coronary heart disease: baseline survey of provision in general practice

OBJECTIVE

To determine secondary preventive treatment and habits among patients with coronary heart disease in general practice.

DESIGN

Process of care data on a random sample of patients were collected from medical records. Health and lifestyle data were collected by postal questionnaire (response rate 71%).

SETTING

Stratified, random sample of general practices in Grampian.

SUBJECTS

1921 patients aged under 80 years with coronary heart disease identified from pre-existing registers of coronary heart disease and nitrate prescriptions.

MAIN OUTCOME MEASURES

Treatment with aspirin, beta blockers, and angiotensin converting enzyme inhibitors. Management of lipid concentrations and hypertension according to local guidelines. Dietary habits (dietary instrument for nutritional evaluation score), physical activity (health practice indices), smoking, and body mass index.

RESULTS

825/1319 (63%) patients took aspirin. Of 414 patients with recent myocardial infarction, 131 (32%) took beta blockers, and of 257 with heart failure, 102 (40%) took angiotensin converting enzyme inhibitors. Blood pressure was managed according to current guidelines for 1566 (82%) patients but lipid concentrations for only 133 (17%). 673 of 1327 patients (51%) took little or no exercise, 245 of 1333 (18%) were current smokers, 808 of 1264 (64%) were overweight, and 627 of 1213 (52%) ate more fat than recommended.

CONCLUSION

In terms of secondary prevention, half of patients had at least two aspects of their medical management that were suboptimal and nearly two thirds had at least two aspects of their health behaviour that would benefit from change. There seems to be considerable potential to increase secondary prevention of coronary heart disease in general practice.

Secondary prevention clinics for coronary heart disease: randomised trial of effect on health

OBJECTIVE

To evaluate the effects of secondary prevention clinics run by nurses in general practice on the health of patients with coronary heart disease.

DESIGN

Randomised controlled trial of clinics over one year with assessment by self completed postal questionnaires and audit of medical records at the start and end of the trial.

SETTING

Random sample of 19 general practices in northeast Scotland.

SUBJECTS

1173 patients (685 men and 488 women) under 80 years with working diagnoses of coronary heart disease who did not have terminal illness or dementia and were not housebound.

INTERVENTION

Clinic staff promoted medical and lifestyle aspects of secondary prevention and offered regular follow up.

MAIN OUTCOME MEASURES

Health status measured by the SF-36 questionnaire, chest pain by the angina type specification, and anxiety and depression by the hospital anxiety and depression scale. Use of health services before and during the study.

RESULTS

There were significant improvements in six of eight health status domains (all functioning scales, pain, and general health) among patients attending the clinic. Role limitations attributed to physical problems improved most (adjusted difference 8.52, 95% confidence interval 4.16 to 12. 9). Fewer patients reported worsening chest pain (odds ratio 0.59, 95% confidence interval 0.37 to 0.94). There were no significant effects on anxiety or depression. Fewer intervention group patients required hospital admissions (0.64, 0.48 to 0.86), but general practitioner consultation rates did not alter.

CONCLUSIONS

Within their first year secondary prevention clinics improved patients' health and reduced hospital admissions.
