I. Aim Stranding sea turtle and their long hospitalization case is a worldwide resource and finance issue. However, the relationship between clinical findings and outcomes of rehabilitation is not usually discussed. This study aim to set up a prognostic system to predict the prognosis of rescue sea turtles, and eventually, use the resource efficiently. II. Method & material Overall, there were forty-two sea turtles rescued from northern Taiwan during September, 2012 and June, 2016. All turtles were tested for thirty-one items. The relation of different rehabilitation period and clinical tests was analyzed by chi-squared test, odds ratio and principle component analysis by order. The most significantly related factors were recognized after the analysis. III. Result Overall, the mean rehabilitation period was 52±74.24 days. It was noted that the proportion of rehabilitation time longer and less than two months were both nearly a half. After statistic analysis, the most relative factor between clinical exam and rehabilitation time were: increasing in uric acid, lymphopenia, hypoalbuminemia, albumin/ total protein ratio, heterohil/ lymphocyte ratio and buoyancy problem. These six factors will be used to set up a clinical system of prognosis prediction. It was tested for ROC curve, and the AUC was 0.715, with 75% sensitivity, 75% specificity at the cut-off point 13.475. The positive likelihood was 3.0. IV. Discussion The six factors was high consistence with other prognostic research of human medicine and small animal medicine, and was mentioned in other stranded sea turtles widely. That indicates the high reliability. The six factors were strong related to the clin-ical diagnosis of turtle. It indicated that the associated pathological changes and af-fected organs will be the point of rehabilitation. And they will affect the time of recov-ery and release. The system was acceptable as well. But it will be needed to improve by alternation and validation. V. Conclusion The research can use to predict the rehabilitation time about rescued sea turtles. The result supports the acceptable performance of prognostic prediction. The period of rehabilitation can be assessed with these six factors. Therefore, it is possible to improve the efficacy and shorten the time of rehabilitation. And, the cost of examination re-source can be controlled as well. The research provides a preliminary result of evidence to predict prognosis in rescued turtle in wildlife rehabilitation.
