Clinical issues on consent: some philosophical concerns.

On occasions, laws on consent are subject to modification, largely on account of being subject to common law rather than statute-for example, in the UK. Guideline publications such as the UK Department of Health Reference Guide to Consent for Examination or Treatment are intended to provide information for clinicians on when and how to apply current laws in everyday clinical situations. While the extent to which guidelines influence clinician behaviour depends on how much they are read and followed, what is also relevant, and sometimes omitted from consideration, is discussion about underlying philosophical concepts. This paper analyses philosophical weaknesses relating to English laws on consent, the main focus of attention being applied ethics and the rights of adults with incapacity. It draws comparisons between the US and the UK, and advocates changes in English law in order to help rectify weaknesses in patient protection. Discussion includes references to Scottish law, and the use of advance directives, and it voices concerns about over-reliance on "best interests" determinations. The problem is partly one of logical analysis, and what can happen is that best interests determinations fail to show proper respect for adults lacking the capacity to consent to examination or treatment on their own behalf. This is fundamentally a matter of rights, and requires further investigation and appropriate legal remedies in order to respond to ethical deficiencies in English law as it now stands.

Prospective randomised double-blind trial of the in vivo use of recombinant human erythropoietin in bone marrow transplantation from HLA-identical sibling donors. The Australian Bone Marrow Transplant Study Group.

Ninety one patients between the ages of 17 and 58 years undergoing histocompatible allogeneic transplants from sibling donors were entered into a double-blind randomised trial to evaluate the effect of human erythropoietin (rhu EPO) at a dose of 300 units per kg/day given thrice weekly by intravenous injection on erythropoiesis and on erythrocyte and platelet transfusion requirements. Dose was ceased when the haemoglobin exceeded 12g/dL and recommenced if the haemoglobin fell below 12 g/dL, at 150 units/kg/day. If the haemoglobin exceeded 12 g/dL on a further occasion, the dose of rhu EPO was not given. Patients received two units of erythrocytes when the haemoglobin dropped below 8.5g/dL and received platelet transfusions when the count dropped below 20 x 10(9)/L. Univariate analysis revealed a significantly higher reticulocyte count, haemoglobin concentration and bone marrow erythropoiesis after day 14 in the group receiving rhu EPO but this was not reflected in decreased erythrocyte transfusion (7 +/- 5 in controls versus 6 +/- 5 in rhu EPO group) or in platelet transfusions (11 +/- 7 in controls versus 11 +/- 9 in rhu EPO group). Hospitalisation in each group was the same (29 +/- 8 in the control group and 28 +/- 8 in the rhu EPO group). However, in the multivariate analysis, the administration of rhu EPO was associated with an 18% reduction in erythrocyte transfusion requirement when other variables were taken into account. No side-effects due to rhu EPO were detected in this study.(ABSTRACT TRUNCATED AT 250 WORDS)

Architecture: client/server moves into managed healthcare.

The healthcare industry is in transition from indemnity-based products to managed care during a period marked by consolidation, competitiveness and increasingly demanding consumers. This powerful combination of industry change and customer interest requires more efficient operations and flexible information systems. Host-based managed care systems are running into limitations meeting business needs, creating a demand for client/server architectures.
