The reform of UK research ethics committees: throwing the baby out with the bath water?

On 1 May 2004 research ethics committees became legally accountable to a new government body, the United Kingdom Ethics Committee Authority. This marks the end of the self regulation of research ethics. This paper describes how this change in research ethics committee status has come about and explores the implications for research subjects, researchers, institutions, and for regulation of research.

Urachal adenocarcinoma in situ with pseudomyxoma peritonei: a case report.

A 54 year old man presented with a six month history of abdominal pain. A computerised tomography scan showed a well defined intra-abdominal unilocular mass with a calcified wall just superior to the bladder. At laparotomy, pseudomyxoma peritonei was discovered, together with a midline abdominal mass adherent to the anterior abdominal wall originating from the fundus of the bladder. The specimen consisted of a cystic mass measuring 14 x 9.5 x 7 cm overall, which contained mucoid material. Histological examination revealed that the cyst was lined by mucinous epithelium, which in areas varied from having bland morphology to showing pronounced nuclear and architectural atypia. There was abundant extracellular mucin. The specimen was extensively sampled but there was no evidence of invasion. This tumour has many unusual features, namely: the absence of destructive invasion, association with pseudomyxoma peritonei, areas of dysplasia and cystadenoma, and stromal osseous metaplasia within the wall.

Cytokeratin 7: a useful adjunct in the diagnosis of chromophobe renal cell carcinoma.

AIMS: The histopathological diagnosis of chromophobe renal cell carcinoma can present a diagnostic challenge, as these tumours can resemble either conventional renal cell carcinoma or oncocytoma. The aim of this study was to determine whether cytokeratin 7 expression is of practical use in the distinction of these three entities. METHODS AND RESULTS: A total of 40 cases previously diagnosed as either chromophobe renal cell carcinoma, conventional renal cell carcinoma or oncocytoma were identified. A representative section of each was stained with H&E and cytokeratin 7. Following independent review of the cases by three pathologists, a consensus diagnosis for each case was reached and the pattern of cytokeratin 7 staining was assessed. There were 12 cases of chromophobe renal cell carcinoma in the study, all of which showed a characteristic peripheral membrane pattern of staining for cytokeratin 7. Seventeen of the 18 cases of conventional renal cell carcinoma studied were negative for cytokeratin 7, while one case showed weak focal staining of <5% of the cells. The 10 cases of oncocytoma showed patchy weak to moderate cytoplasmic expression of cytokeratin 7, without the characteristic peripheral membrane accentuation seen in the chromophobe carcinomas. CONCLUSIONS: Immunohistochemical staining for cytokeratin 7 appears to be a useful adjunct in the diagnosis of chromophobe renal cell carcinoma, and in distinguishing this tumour from both oncocytoma and conventional renal cell carcinoma.

The use of acute hospital services by elderly residents of nursing and residential care homes.

The objective of this study was to compare hospitalisation rates by cause of admission, hospital death rates and length of stay for residents from nursing and residential care homes with those in the community. This is a retrospective study of acute hospital emergency admissions in one health district, Merton, Sutton and Wandsworth between April 1996 and March 1997. Data linkage and manual look up were used to derive emergency hospital admissions for residents of care homes aged 65 and over. Admission rates were calculated for cause, length of stay and hospital death for residents of care homes and in the community with relative risks. The relative risk of emergency admission from a care home compared with the community was 1.39 for all diagnoses, 2.68 for all injuries, and 3.96 for fracture of neck of femur. The relative risk of dying in hospital for care home residents was 2.58 overall, and 3.64 in the first 48 hours of a hospital stay (all P-values <0.0001). Admission rates were higher from residential than from nursing homes. There was some increase in admissions from homes during holiday periods and over Christmas. In conclusion, there are major difficulties in monitoring admissions from nursing and residential care homes due to poor quality recording and inaccuracies in NHS coding. This was compounded by an absence of data on the age and sex profile and healthcare needs of the resident population in care homes. Prospective studies are required to ascertain when admission is avoidable and when it is appropriate. The information strategy needs to ensure that routine data sources are capable of monitoring the use of hospital services by residents of care homes.

Absent voices compromise the effectiveness of nursing home regulation: a critique of regulatory reform in the UK nursing home industry.

Over the last decade there has been consistent pressure for the healthcare services in the UK to become more accountable to users. Now over half the healthcare beds in England are in the privatised nursing home sector, and regulation of the sector is under reform. Yet requirements for user accountability have not been reflected in these reforms. In other sectors, consumer involvement in regulatory agencies and processes is seen as important to the success of the regulatory enterprise. But in the care sector neither users nor their representatives have been given legal rights of involvement in the National Care Standards Commission or in regulatory processes. This paper argues that failure to involve users not only places the regulation enterprise at risk of capture by the industry, but will also weaken the legitimacy of the new Commission.

The British Labour government's reform of the National Health Service.

The recent general election in Britain saw healthcare as the dominant issue amongst voters. The victorious Labour Party responded to this concern with a set of reforms designed to introduce greater private-sector involvement in the delivery of healthcare. These reforms are ill-thought-out. The standard of care in British private hospitals is below that found in public hospitals, whilst new contracting arrangements are likely to increase the administration costs within the system. Faith in private-sector management techniques is misplaced at a time when the real problem facing the NHS is that of capacity. The Labour Party is also committed to redefining some aspects of healthcare as a personal responsibility and not a right, moving Britain towards a more market-based healthcare system.

Rewriting the regulations: how the World Trade Organisation could accelerate privatisation in health-care systems.

The World Trade Organisation (WTO) is drawing up regulatory proposals which could force governments to open up their public services to foreign Investors and markets. As part of the General Agreement on Trade in Services (GATS) negotiations, the WTO working party on reform of domestic regulation is developing a regulatory reform agenda which could mark a new era of compulsion in international trade law. Article VI.4 of the GATS is being strengthened with the aim of requiring member states to show that they are employing least trade-restrictive policies. The legal tests under consideration would outlaw the use of non-market mechanisms such as cross-subsidisation, universal risk pooling, solidarity, and public accountability in the design, funding, and delivery of public services as being anti-competitive and restrictive to trade. The domestic policies of national governments will be subject to WTO rules, and if declared illegal, could lead to trade sanctions under the WTO disputes panel process. The USA and European Union, with the backing of their own multinational corporations, believe that these new powers will advantage their own economies. Health-care professionals and public-health activists must ensure that this secretive regulatory reform process is opened up for public debate.

Reducing DCO registrations through electronic matching of cancer registry data and routine hospital data.

The Thames Cancer Registry (TCR) has registered a high proportion of tumours from death certificate information only (DCO) registrations. This paper describes the results of a study set up to establish whether this proportion could be reduced by linking cancer registrations with routine hospital data from the Hospital Episodes Statistics (HES) data set using computerized matching. A total of 67752 registrations were identified from the TCR. Matches were found in the HES data set for 66%. The proportion of cases retrieved for each tumour site was: 72% for colorectal cancer; 62% for cancer of the lung, trachea or bronchus; and 65% for female breast cancer. For all three tumour sites the proportion of matches found for patients registered from hospital case notes was higher than the proportion found for patients registered as DCOs (P < 0.0001 for all three tumour sites). Among matched DCO cases, 58% had at least one procedure recorded. DCO rates might be reduced by as much as 43% (from 17% of total registrations to less than 10%) for the three most common cancers if the method of electronic matching outlined here was used. Younger age groups, prognosis of tumour site and residence in North Thames region were all positively associated with successful matching (P < 0.0001 in all three cases). Many matched DCO cases were found to have had more than one admission for cancer. Among ordinary in-patient admissions, admissions to patients ratios of 1.5, 1.4 and 1.9 were found for colorectal, lung and breast cancers respectively. Of 5190 matched DCOs a procedure was recorded for 3013 (58%). HES data offer a useful aid to follow-up of case notes on patients identified to the registry by death certificates. Doubts about the completeness and accuracy of HES data mean case notes must remain the 'gold standard'.

How the World Trade Organisation is shaping domestic policies in health care.

High up on the agenda of the World Trade Organisation (WTO) is the privatisation of education, health, welfare, social housing and transport. The WTO's aim is to extend the free market in the provision of traditional public services. Governments in Europe and the US link the expansion of trade in public services to economic success, and with the backing of powerful medico-pharmaceutical, insurance, and service corporations, the race is on to capture the share of gross domestic product that governments currently spend on public services. They will open domestic European services and domestic markets to global competition by government procurement agreements, dispute-settlement procedures, and the investment rules of global financial institutions. The UK has already set up the necessary mechanisms: the introduction of private-sector accounting rules to public services; the funding of public-sector investment via private-public partnerships or the private finance initiative; and the change to capitation funding streams, which allows the substitution of private for public funds and services. We explain the implications of these changes for European public-health-care systems and the threat they pose to universal coverage, solidarity through risk-pooling, equity, comprehensive care, and democratic accountability.
