Abstract

|
|
Objective:Estimation of the life expectancy (LE) for patients in a persistent vegetative state (PVS) or minimally conscious state (MCS) depends on the statistical probability. Since the statistics of LE increases year by year, we should update the ratio of expected life spans based on the recent data.
Methods:We searched recent (after January 2000 to June 2010) articles on the LE and PVS using PubMed. We excluded letters or comments. Using data from the literature review and the life table of Korean National Statistical Office, we proposed a scheme estimating the LE for PVS and MCS patients after head injuries
Results:There were three papers on the mortality or LE of PVS or MCS patients. To diagnose PVS and MCS correctly, we should use the revised coma recovery scale. The reported LE of PVS and MCS patients was longer than when the Lee’s scheme was applied. The ratio of LE would be 10-25% for PVS, 20-40% for MCS fed by others, and 40-70% for MCS self fed.
Conclusion:We reviewed diagnostic criteria for the PVS and MCS. For updated estimation of the individual LE for PVS or MCS, we proposed a method based on the recent data from the literature review.
