A method was developed for evaluating outcomes of nursing care in complex situations such as care of people who are dying. Positive outcomes of care for patients that were directly attributable to the care provided by Macmillan specialist palliative care nurses were found for the majority of patients. For a small number of patients, negative outcomes of care were identified.

Further support and training may improve confidence and positive experiences in relation to DNAR decision-making among training-grade doctors in the UK.

The remit and boundaries of the Macmillan Nursing role in the UK have been called into question recently by a number of policy-driven changes. The rapid appointment of tumour site-specific nurses and the development of posts for palliative medicine, stemming originally from the Calman-Hine recommendations for reorganizing cancer services, have created unparalleled challenges of adaptation to new working practices and procedures. The extent to which Macmillan Nurses are adapting to these new demands was addressed as part of a major evaluation study of UK Macmillan Nursing in 12 sites commissioned by the UK charity Macmillan Cancer Relief. This paper draws upon semi-structured interviews with Macmillan Nurses (n = 44) and their key colleagues (n = 47). We found that differences of expectation between Macmillan Nurses and their managers about the appropriate focus of their work lead to problems of role ambiguity and role conflict; that Macmillan Nurses lack resources with which to develop an educative and consultative role and yet substitute for inadequacies in skills and knowledge of other health care staff; and that problems are associated in co-working with newly appointed cancer site-specific nurses and palliative medicine colleagues. Macmillan Nursing has a crucial role to play in meeting the objectives in the NHS Cancer Plan. However, in order to ensure that their expertise is used efficiently and effectively, there is an urgent need to clarify the nature and scope of the Macmillan Nurse role, to attend to issues of team working and to improve the skills of nonspecialist staff in palliative care.

Macmillan Nurses play a significant role in specialist palliative care services in the UK, providing direct and indirect services to patients with complex palliative care needs and to their families. Existing literature shows a developing understanding of the role; however, little detailed data exist regarding the clinical work that they undertake. This paper provides evidence from a major evaluation study, commissioned by Macmillan Cancer Relief. It reports the methods of data collection for the study and then goes on to use data from the evaluation to describe the caseload of Macmillan Nurses. Between September 1998 and October 1999, a team of researchers worked alongside 12 Macmillan teams for a period of 8 weeks with each team. Prospective data were gathered on all new referrals to the services within the 8-week period. This included demographic details, timing of referral, the nature and purpose of contacts, and interventions, recorded from case notes and Macmillan Nurse records. Where possible, a date of death was obtained for all patients. A total of 814 new patients were referred during the study period (range 45-114 per site). The most common reasons for referral were emotional care for the patient (57%), pain control (27%), and other physical symptoms (33%). Thirteen per cent of the patients referred to the services died within 1 week of referral while 40% died within 6 weeks; thus, a significant proportion of patient work is focused on care at the end of life. It is also noteworthy that one-third of patients were still alive, indicating that some patients are being cared for earlier in the illness trajectory. On average, each new patient referral received two or more 'face-to-face' visits and two follow-up phone calls within the 8-week period. It would appear that Macmillan Nurse teams have been successful in getting access to relevant patients. As with any service that provides a complex set of interventions, the Macmillan teams have to adapt and develop the services in each setting. Whilst it is clearly important for the development of a Macmillan service to be tailored to the local conditions, the evidence on diversity suggests that in some cases, stronger guidance, in partnership with both Macmillan Cancer Relief and core providers, may be justified.

The relatively high number of death certificates that do not record the presence of a valve prosthesis and the observed under-reporting of post mortems may lead to inaccurate reporting of the number of BSCC valves that fail. Previous recommendations to improve accuracy in death certification appear to have gone unheeded, and changes in the way certificates are completed for patients with implanted cardiac devices should be considered.

Objective-To investigate the risk of outlet strut fracture (OSF) in Björk-Shiley convexo concave (BSCC) valves in relation to patients' clinical and valve characteristics. Design-A cohort of 2977 patients with 3325 valves with a follow up of 18 years. Setting-38 cardiac implantation centres in the UK. Results-56 OSF events were reported with 43 occurring in mitral and 13 in aortic valves. The overall OSF rate was 0.17%/year. No dominant clinical factor of risk was found, but multiple regression analysis identified age, body surface area, valve size, shop order fracture rate, and manufacturing period as risk factors for OSF. A 4% (95% confidence interval (CI) 2% to 6%) decrease in the risk of OSF was observed for each advancing year of age and a fivefold (95% CI 2 to 13) increase in risk for a 0.5 m 2 increase in body surface area. The association between the risk of OSF and valve size was not constant over time. Excess risks among 31 mm and 33 mm sizes (mainly mitral valves) decreased over time while that for 23 mm (almost all aortic valves) increased. The risk of OSF increased by 40% (95% CI 20% to 50%) for a unit increase in the fracture rate of other valves in the same batch. For valves manufactured during 1981 to 1984 the risk of OSF was 4 (95% CI 2 to 12) times greater than for valves manufactured before 1981. Conclusions-The OSF rates for 60°BSCC valves observed in the UK are the highest among all monitored populations. The changing patterns of mitral and aortic valve OSF rates over time observed in this study have not been identified previously and highlight the need for continued monitoring of patients with the BSCC valve.

Economic evaluation of specialist nursing interventions is challenging because of the complex nature of interventions and the difficulty of describing nursing outcomes in simple ways. This article discusses data from a study of Macmillan specialist cancer nursing. Resource-use data and nursing-outcome data were collated from 76 case studies of patients referred to 12 specialist cancer and palliative nursing teams (home-based and hospital-based) in the UK. Specific outcomes related to nursing were defined, and cost and nursing outcome data were analysed together. The data suggested that patients who reported better nursing outcomes had a higher proportion of specialist nursing interventions than those reporting poor nursing outcomes (45% versus 25%). Also, the overall pattern of health-care use was different for those patients who reported positive nursing outcomes. This suggests that positive nursing outcomes can influence patients' access to other health services. The data supported specific hypotheses regarding ways that specialist nurses can influence the cost-effectiveness of care. These data do not constitute a comparative evaluation study, as no control group was identified. Such results are nevertheless important as this type of data has not been gathered previously.

In the UK, the work of Macmillan clinical nurse specialists in palliative care is now well established. There has been little research, however, into the organizational context in which these nurses operate and the implications for the services they deliver. We report on a major evaluation of the service delivery, costs, and outcomes of Macmillan nursing services in hospital and community settings. The study was based on eight weeks of fieldwork in each of 12 selected services. Data are presented from semi-structured interviews, clinical records, and cost analysis. We demonstrate wide variation across several dimensions: location and context of the services; activity levels; management patterns; work organization and content; links with other colleagues; and resource use. We suggest that such variation is likely to indicate the existence of both excellent practice and suboptimal practice. In particular, our study highlights problems in how teamwork is conceptualized and delivered. We draw on recent organizational theories to make sense of the heterogeneous nature of Macmillan nursing services.
