Costing interventions in primary care.
Against a background of increasing demands on limited resources, studies that relate benefits of health interventions to the resources they consume will be an important part of any decision-making process in primary care, and an accurate assessment of costs will be an important part of any economic evaluation. Although there is no such thing as a gold standard cost estimate, there are a number of basic costing concepts that underlie any costing study. How costs are derived and combined will depend on the assumptions that have been made in their derivation. It is important to be clear what assumptions have been made and why in order to maintain consistency across comparative studies and prevent inappropriate conclusions being drawn. This paper outlines some costing concepts and principles to enable primary care practitioners and researchers to have a basic understanding of costing exercises and their pitfalls.
A cost consequence study of the impact of a dermatology-trained practice nurse on the quality of life of primary care patients with eczema and psoriasis.
BACKGROUND: The practice nurse is central to the development of a primary care-led National Health Service. Skin diseases can have a major impact on patients' lives but general practitioners (GPs) lack many of the skills of practical dermatology care and support. AIM: To determine whether a primary care dermatology liaison nurse should be introduced by our health authority. We identified the resources consumed and the benefits that accrued from a practice nurse who had received training in practical dermatology care. METHOD: A cost consequence study in parallel with a randomised controlled trial was undertaken in a group of nine GPs and 109 patients between the ages of 18 and 65 years who had a diagnosis of psoriasis or eczema. RESULTS: Although there was a significant improvement in our primary outcome measure within group, when compared with the control group significance was not achieved. There was no significant change in the Euroqol measure but the clinical instrument showed a significant change when compared with control. On entry, our qualitative data identified three main themes--the embarrassment caused by these skin conditions, the wish for a cure rather than treatment, and concern over the long-term effects of steroids. On completion, 20% of patients expressed that they had received a positive benefit from the clinic. CONCLUSION: This study demonstrates the difficulties of obtaining relevant information to facilitate decisions on how resources should be allocated in primary care. Not all questions can be answered by large multi-centred trials and studies themselves have an opportunity cost consuming resources that could otherwise be spent on direct health care. Often, local resource decisions will be based on partial evidence-yielding solutions that are satisfactory rather than optimum but which are, nevertheless, better than decisions taken with no evidence at all.

Ambulatory blood pressure monitoring for hypertension in general practice.
Ambulatory blood pressure monitoring (ABPM) is being increasingly used in general practice. There is at present little published evidence regarding the clinical utility of ABPM in the care of patients with established hypertension in this setting. We examined this issue by undertaking ABPM in a group of patients with established hypertension. 40 patients (aged 33-60 years) currently being treated for hypertension were randomly selected from a general practice list and underwent a single 24-hour ABPM study. ABPM values were compared with clinic blood pressure (CBP) values obtained on the day of monitoring together with previous readings taken by the general practitioner (GP). In the case of mean arterial pressure, 24-hour, awake and asleep ABPM values were found to underestimate CBP values by 14 mmHg (95% confidence interval 11-16 mmHg), 9 mmHg (95% C16-12 mmHg) and 24 mmHg (95% CI 21-27 mmHg), respectively. When used to classify blood pressure control, ABPM values produced equivalent results to CBP except by the criterion of BP load, for which 24-hour ABPM showed a higher rate of unsatisfactory control. 5 patients classified by CBP to have satisfactory BP control according to current international guidelines were found to have unsatisfactory BP control by ABPM. This study demonstrates the potential value of ABPM in patients with essential hypertension in a general practice setting. ABPM provided information over and above that obtained by CBP in a substantial proportion of patients.
