Rapid detection of bacteraemia by early subculture.

Inspection and blind subculture was carried out on 7031 consecutive blood cultures at 10 p.m. on the day they were received. Analysis of the results after a 2-year period showed that 119 out of 237 (50%) bacteraemic patients were detected at this stage. Preliminary sensitivity tests were done at this time and their results were available within 24 h of the blood cultures being received. Thus earlier specific therapy was possible in 50% of the cases of bacteraemia.

Report on a multiple regression method for making population estimates.

A new method of making population estimates is introduced and contrasted to the standard ratio-correlation method. The new method, called the "difference-correlation method," produced population estimates for the counties of Michigan which had a smaller mean percentage error than estimates produced by the ratio-correlation method. The differences of proportions which are used in the difference-correlation method will always have means of zero, while the ratios used in the ratio-correlation method have means which vary. Higher intercorrelations among the variables and increased temporal stability of the intercorrelations are two advantages of using differences rather than ratios.
