Mean Sojourn Time

Many parameters are needed in the assessment of the benefits of a periodic screening program. In this paper we present formulas for two of them: the proportion SP of patients detected and the lead time of such a program. The lead time is the time by which the disease is detected earlier due to screening. We also give a lower bound for the mean lead time L in terms of the mean sojourn time in a certain preclinical state P and of the sensitivity of the screening test in this state P only. Finally, we indicate how the mean sojourn time and, under certain assumptions, even the sensitivity are estimated from the results during the initial phase of the screening program.

The Mean

Swab samples were obtained from the surfaces of randomly selected beef carcasses passing through a high-speed dressing process. A single sample was obtained from a randomly selected site on the surface of each selected carcass. Fifty such samples were collected at each of four stages in the process. The aerobic bacteria, coliforms, and Escherichia coli recovered from each sample were enumerated. Values for the mean log units and standard deviations of each set of 50 log values were calculated on the assumption that the log values were normally distributed. The log of the arithmetic mean was estimated from the mean log and standard deviation values for each set. The results show that the average numbers of E. coli, coliforms, and aerobic bacteria which are deposited on carcasses during skinning and evisceration are not reduced by trimming, and that washing approximately halves the average numbers of those bacteria on carcasses. It is concluded that commercial trimming and washing operations are not effective means of decontaminating beef carcasses.
