Analysis from inner London of deprivation payments based on enumeration districts rather than wards.

OBJECTIVE: To estimate the effect of calculating the Jarman index using the smaller geographical unit of the census enumeration district on the changes in deprivation payments made to general practitioners. The Jarman index, or underprivileged area score, is used to calculate the allowance that general practices in the United Kingdom receive for each patient registered with them who lives in an area of relative social deprivation. Current values of the Jarman score are derived from the 1981 census and are based on electoral wards. The change in payments to some practices brought about by using data from the 1991 census may cause severe financial hardship. DESIGN: Jarman indices for wards and enumeration districts from the 1981 and 1991 censuses were used to calculate the payments made to 169 practices in Lambeth, Southwark, and Lewisham; the changes in payments under ward and enumeration district based schemes were then compared. MAIN OUTCOME MEASURES: Standard deviations of the changes in payments to practices. Extreme values of changes in payments. RESULTS: The standard deviation of the change in payment between the two censuses was 6365 pounds with the enumeration district Jarman index, whereas it was 9452 pounds under the ward based scheme. If the ward based scheme is used 10 practices would find their payments changed by over 20,000 pounds, whereas only two practices would have changed by more than this amount under the scheme based on enumeration districts. CONCLUSION: The Jarman index could be more sensitively and appropriately applied to calculate the deprivation payments that practices receive using the census enumeration district as its unit for calculation. This would result in fewer precipitate changes in payments when census data change every 10 years.

Initial management and transport of patients with perforating eye injuries.

The first 24 hours are critical for a good surgical result from perforating eye injuries. The basic principles of initial management and transfer include prevention of vomiting, pain and infection, and avoidance of further injury. Where air transport is necessary it must be with the cabin altitude at sea level, or as low as is safe. Surgical repair should be undertaken as promptly as is practical.

Maximal treadmill tests five years apart in asymptomatic men aged 45-72 years.

169 asymptomatic male volunteers aged 45-72 years not taking part in any fitness or intervention program performed two maximal treadmill tets (Bruce protocol) five years apart. Treadmill endurance time declined 4 to 8 seconds per year; 72% of subjects had changes in endurance time of less than one minute. Maximal heart rate declined about 1 beat/min-1 per year. Horizontal or downsloping ST segment depressions of 0.1 mv or more or slowly upsloping ST depressions of 0.2 mv or more occurred in 26% of subjects at test 1, 38% of subjects at test 2. 25% of subjects with ST abnormality at test 1 were normal at test 2, and 26% of subjects with a normal ST segment at test 1 were classified as abnormal at test 2. Ventricular ectopic beats during or after exercise occurred in 22% of subjects at test 1 and in 37% of subjects at test 2, and the frequency of complex ventricular ectopic activity increased from 2% at test 1 to 9% at test 2. There is a high frequency of exercise induced ventricular extrasystoles, and ST depression in a normal population of older men and it is not known whether there is any need for intervention.
