Analysing the 'new' British National Health Service.

The British National Health Service (NHS) has seen a proliferation of confusing and sometimes conflicting labels in recent years. It has been claimed that during the Conservative Government's period of office the 'classic' NHS was 'restructured' and then turned into the 'new' NHS. The New Labour Government of 1997 has claimed that it will deliver a 'new' NHS. If all these claims are correct, it should be possible to identify four distinct periods, with three clear 'breaks of slope' with significant changes in important indices on moving from one label to another. This paper attempts to look behind these labels by critically examining what has changed in the NHS since 1979. In simple terms, what has been 'restructured'? What is new about the 'new' NHS? Why are these changes important? It is concluded that while the NHS has certainly undergone significant changes in the past 20 years or so, the appearance of a 'new' NHS may be premature as in many areas it is possible to see the marks of continuity as well as change, and policy impact is characterised by greater incrementalism than policy rhetoric.

On a hiding to nothing? Assessing the corporate governance of hospital and health services in New Zealand 1993-1998.

In New Zealand the governance of public sector hospital and health services has changed significantly over the past decade. For most of the century hospitals had been funded by central government grants but run by locally elected boards. In 1989 a reforming Labour government restructured health services along managerialist lines, including changing governance structures so that some area health board members were government appointments, with the balance elected by the community. More market oriented reform under a new National government abolished this arrangement and introduced (1993) a corporate approach to the management of hospitals and related services. The hospitals were established as limited liability companies under the Companies Act. This was an explicitly corporate model and, although there was some modification of arrangements following the election of a more politically moderate centre-right coalition government in 1996, the corporate model was largely retained. Although significant changes occurred again after the election of a Labour government in 1999, the corporate governance experience in New Zealand health services is one from which lessons can, nevertheless, be learnt. This paper examines aspects of the performance and process of corporate governance arrangements for public sector health services in New Zealand, 1993-1998.

Resistance to trimethoprim in Haemophilus influenzae.

The mechanisms of resistance to trimethoprim in eleven U.K. clinical isolates of Haemophilus influenzae were studied. The levels of dihydrofolate reductase (DHFR) activities in crude extracts from four resistant wild-types were similar to those in susceptible controls. However, activities in extracts from the other seven resistant wild-type isolates, and transformants of two of these, were at least triple those in the sensitive strains. Resistance to trimethoprim was also selected for in vitro during prolonged exposure to the drug and was associated with increased levels of DHFR specific activity in the mutants. DHFR enzymes were, however, still very susceptible to inhibition by trimethoprim. Activities in four extracts, including one from a transformant of a resistant mutant, were reduced by at least 45% following incubation with 10(-8) M trimethoprim. The results suggested that overproduction of the chromosomal DHFR enzyme may be the resistance mechanism in some organisms. The much lower DHFR activities measured in extracts from other resistant isolates may reflect synthesis of chromosomal enzymes that have reduced susceptibility to trimethoprim.

Psychiatric attendant-led rehabilitation groups.

Because active treatment is indicated as a patient care priority by both staff and regulatory agencies, innovative ways to utilize available staff to provide treatment needs to be further developed. The Logansport Hospital program provides one example for training experienced attendants in conducting exercise, relaxation, and discussion groups. It has enabled increased programming for patients and has been positively evaluated by our staff.
