Is publicly funded health care really distributed according to need? The example of cardiac rehabilitation in the UK.

OBJECTIVES: To demonstrate the importance of measuring both the horizontal and vertical components of equity in order to examine whether patients are receiving the health care that they need. METHODS DESIGN: A theoretical demonstration followed by analysis of a prospectively collected national random sample of acute cardiac admissions to 94 hospitals in the UK. PATIENTS: One thousand and sixty-four patients under 70 years old. ANALYSIS: The association between use of cardiac rehabilitation and gender (after adjusting for clinical need) was measured using multivariable analysis with effect modification. RESULTS: Hypertensive males were nearly twice as likely to undergo rehabilitation compared with hypertensive females (OR 1.76, 95%CI 1.03-3.02). Hyertensive patients were less likely to undergo rehabilitation than normotensive patients (OR 0.67, 95% CI 0.50-0.89) but this treatment difference did not apply in the same way to both men and women. Hypertensive women were half as likely to undergo rehabilitation compared with normotensive women (OR 0.48, 95% CI 0.30-0.78), whereas hypertensive men were as likely as normotensive men to receive rehabilitation (OR 1.00. 95%CI 0.63-1.60). CONCLUSIONS: Horizontal inequity was demonstrated because male and female hypertensive patients with equal needs were not treated equally. There was also vertical inequity because although patients with hypertension were treated differently to normotensive patients, this treatment difference was not the same for men and women.

From health technology assessment to research on the organisation and delivery of health services: addressing the balance.

This paper argues that the focus of research to improve health services has, until recently, been on health technology assessment. The authors make the case for a greater emphasis on research on how health services are managed, organised and delivered, and refer to initiatives in a number of countries which are seeking to address this balance. The way two such initiatives in England and Canada have set priorities for this type of research, involving a wide range of stakeholders is described. The authors argue that a wide range of disciplines needs to be applied to research on the organisation and delivery of health services. Important theoretical differences between and within disciplines, and their implications for research methods, are discussed. An example of an issue in the delivery of organisation of health services (how best to deliver orthopaedic care) is used to illustrate how a number of different disciplines can be applied. The challenge for researchers from these disciplines is to see how far they can work together to carry out research in this important field. The challenge for this research is that the findings are valued and used by health service professionals, managers and users.

Secondary use of personal data for health and health services research: why identifiable data are essential.

Databases provide a powerful and essential resource for health and health services research. There are seven reasons why the identification of individuals may be needed: linkage within a database; linkage between databases; ensuring comparisons are meaningful; ensuring completeness of recruitment; investigation of social factors; analysis of trends over time; and assessing the applicability of primary research findings. Examples of recent British research studies for which identifiable data were essential are described to illustrate six research applications: to understand the natural history and development of disease; to identify causes of disease; to evaluate health care interventions; to assess equity of care; to describe trends in health care utilisation; and to ensure the methodological rigour of research. Given the benefits to the public of such research activities, methods need to be found to ensure the continuation of such research while meeting legitimate concerns about individual privacy and confidentiality.

Systematic review of mental health interventions for patients with common somatic symptoms: can research evidence from secondary care be extrapolated to primary care?

OBJECTIVES: To determine the strength of evidence for the effectiveness of mental health interventions for patients with three common somatic conditions (chronic fatigue syndrome, irritable bowel syndrome, and chronic back pain). To assess whether results obtained in secondary care can be extrapolated to primary care and suggest how future trials should be designed to provide more rigorous evidence. DESIGN: Systematic review. DATA SOURCES: Five electronic databases, key texts, references in the articles identified, and citations from expert clinicians. STUDY SELECTION: Randomised controlled trials including participants with one of the three conditions for which no physical cause could be found. Two reviewers screened sources and independently extracted data and assessed quality. RESULTS: Sixty one studies were identified; 20 were classified as primary care and 41 as secondary care. For some interventions, such as brief psychodynamic interpersonal therapy, little research was identified. However, results of meta-analyses and of randomised controlled trials suggest that cognitive behaviour therapy and behaviour therapy are effective for chronic back pain and chronic fatigue syndrome and that antidepressants are effective for irritable bowel syndrome. Cognitive behaviour therapy and behaviour therapy were effective in both primary and secondary care in patients with back pain, although the evidence is more consistent and the effect size larger for secondary care. Antidepressants seem effective in irritable bowel syndrome in both settings but ineffective in chronic fatigue syndrome. CONCLUSIONS: Treatment seems to be more effective in patients in secondary care than in primary care. This may be because secondary care patients have more severe disease, they receive a different treatment regimen, or the intervention is more closely supervised. However, conclusions of effectiveness should be considered in the light of the methodological weaknesses of the studies. Large pragmatic trials are needed of interventions delivered in primary care by appropriately trained primary care staff.
