Improving the quality of life for patients with angina pectoris: a team approach to disease management.

The evaluation of outcome of management of angina patients is now inextricably linked with an assessment of quality of life. Angina, as a manifestation of coronary heart disease, is a major cause of morbidity and mortality in many countries. Optimal management of patients with angina is of undeniable national and global significance.

This paper attempts to indicate the importance of a team approach and the implications for patients’ quality of life of involving professionals with a variety of different skills. It outlines current guidelines for the management of angina, including aspects of diagnosis, treatment and rehabilitation. Factors of relevance to the management of patients as individuals are discussed. The association of improved quality of life and reduced severity of symptoms with benefit for both the individual and society is considered.

The SPHERE Study: Secondary prevention of heart disease in general practice: protocol of a randomised controlled trial of tailored practice and patient care plans with parallel qualitative, economic and policy analyses. [ISRCTN24081411]

Background: The aim of the SPHERE study is to design, implement and evaluate tailored practice and personal care plans to improve the process of care and objective clinical outcomes for patients with established coronary heart disease (CHD) in general practice across two different health systems on the island of Ireland.CHD is a common cause of death and a significant cause of morbidity in Ireland. Secondary prevention has been recommended as a key strategy for reducing levels of CHD mortality and general practice has been highlighted as an ideal setting for secondary prevention initiatives. Current indications suggest that there is considerable room for improvement in the provision of secondary prevention for patients with established heart disease on the island of Ireland. The review literature recommends structured programmes with continued support and follow-up of patients; the provision of training, tailored to practice needs of access to evidence of effectiveness of secondary prevention; structured recall programmes that also take account of individual practice needs; and patient-centred consultations accompanied by attention to disease management guidelines.

Methods: SPHERE is a cluster randomised controlled trial, with practice-level randomisation to intervention and control groups, recruiting 960 patients from 48 practices in three study centres (Belfast, Dublin and Galway). Primary outcomes are blood pressure, total cholesterol, physical and mental health status (SF-12) and hospital re-admissions. The intervention takes place over two years and data is collected at baseline, one-year and two-year follow-up. Data is obtained from medical charts, consultations with practitioners, and patient postal questionnaires. The SPHERE intervention involves the implementation of a structured systematic programme of care for patients with CHD attending general practice. It is a multi-faceted intervention that has been developed to respond to barriers and solutions to optimal secondary prevention identified in preliminary qualitative research with practitioners and patients. General practitioners and practice nurses attend training sessions in facilitating behaviour change and medication prescribing guidelines for secondary prevention of CHD. Patients are invited to attend regular four-monthly consultations over two years, during which targets and goals for secondary prevention are set and reviewed. The analysis will be strengthened by economic, policy and qualitative components.

Time for treating bone fracture using rhBMP-2: a randomised placebo controlled mouse fracture trial.

Although the mechanisms of osteoinduction by bone morphogenic proteins (BMPs) are increasingly understood, the most appropriate time to administer BMPs exogenously is yet to be clarified.The purpose of this study was to investigate when BMP may be administered to a fracture arena to maximise the enhancement of healing.Forty mice with externally fixed left femoral fractures were randomised into four groups: Group I, the control group was given a placebo of 30 ll saline at day 0; Groups II, III and IV were given 30 ll saline plus 2.5 lg rhBMP-2, at post-operative days 0, 4 or 8, respectively.Sequential radiographs were taken at days 0, 8, 16.On day 22 the mice were sacrificed and both femora were harvested for biomechanical assessment in 3-point bending and histological evaluation.Radiographic analysis indicated that healing of fractures in Groups II and III was significantly greater (p <0.05) than those in Groups I and IV, at both 16 and 22 days post-fracture. The highest median bone mineral content at the fracture site was evidenced in Group III and II.Furthermore, Group III also had the highest relative ultimate load values, followed by Groups II, IV and I.Greater percentage peak loads were observed between Group I and both Groups II and III (p <0.05). Histological examination confirmed that at 22 days post-fracture, only fractures in Groups II and III had united with woven bone, and Groups I and IV still had considerable amounts of fibrous tissue and cartilage at the fracture gap.Data presented herein indicates that there is a time after fracture when rhBMP administration is most effective, and this may be at the time of surgery as well as in the early fracture healing phases.
