The impact of the new subsidy regime in general practice in New Zealand.

The first substantial change in the New Zealand health care reforms was the introduction in February 1992 of a new subsidy and charging regime in general practice. The paper reports on a comparison of data collected before and after the changes, drawing on GP-patient encounter information. Overall, seasonally adjusted levels of utilisation were maintained in the stage before the introduction of the new regime, declined 15% immediately following the changeover and stabilised thereafter. All patient groups were affected by the decline. Although the elderly were temporarily exempt from the changes, their consultations fell by 10%. Utilisation among beneficiaries--minor gainers from the changes--dropped by 30%. Children were more affected overall, adults less so. There was also some suggestion of greater falls for the lowest socio-economic groups. Activities under the direct control of the practitioner--prescribing and the ordering of tests--showed either little turbulence or no clear pattern of change. It is concluded that, although primary care subsidies and charges had been reshaped to favour poorer people, six months after the introduction of these changes there had been no corresponding redistribution of medical care consumed. Indeed, there is a suggestion that some of the groups ostensibly the target of increased assistance may have been adversely affected by the overall decline in utilisation.

Nasal vasomotor oscillations in the cat associated with the respiratory rhythm.

Asymmetrical nasal vasomotor oscillations mediated via the cervical sympathetic nerve have been observed in the spontaneously breathing cat. The vasomotor activity persists after abolition of spontaneous respiration with a neuromotor relaxant agent indicating that the vasomotor activity originates in the respiratory areas of the brain and is not due to any of the mechanical effects of respiration. The nasal vasomotor activity is abolished on hyperventilation indicating that it may be driven from a central respiratory oscillator. The vasomotor activity exhibits a reciprocal activity with oscillations in sympathetic activity alternating from one nasal passage to the other and this may be due to a direct relationship with a nasal cycle in the cat.
