Major Abdominal Cerrahi Sonrası Erken Dönemde Fiziksel Fonksiyon Testinin (PFIT-s) geçerliği

Abstract

Avci, E., Validity of Physical Function ICU Test-scored (PFIT-s) Early Period After Major Abdominal Surgery, Hacettepe University Institute of Health Science, Cardiopulmonary Rehabilitation, Master Thesis Ankara, 2016. Pain, fatigue, respiratory muscle weakness, and decreased functional capacity affect postoperative recovery. It is important to fasten functional recovery and determine the functional level of subjects with a practical and appropriate test. Therefore, we aimed to investigate the validity of PFIT-s while comparing with the tests such as six minute walk test (6MWT) and timed up and go test (TUG) which are often used in literature. At the third postoperative day after abdominal surgery, sixty-four inpatients who were between 18-65 age were included to our study. Criterion and concurrent validity of PFIT-s, relationship between functional tests and respiratory muscle strength using the measurement of maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) were evaluated. Additionally, we compared all measurements and operation-anesthesia time by splitting the datas according to operation sides. The cut off value of PFIT-s at ROC curve was calculated 10.5 points for ordinal score and 8.35 points for interval score. In analysis of ROC curve we observed area under curve of 78.5% ( 95% Confidence Interval-CI 0.67-0.90) with 82% sensitivity 57% specificity, 73.9% positive predictive value, 62.5% negative predictive value. There was a positively moderate correlation between 6MWD and PFIT-s (rho= 0.624 p<0.001). A negative strong correlation was found between 6MWD and TUG (rho=-0.744; p<0.001). The PFIT-s displayed statistically significant a negatively moderate level correlation with TUG (rho= -0.584; p<0.001). The PFIT-s has criterion and concurrent validity early period after major abdominal surgery to measure physical function and it can be used at this period as an alternative and a safe test instead of tests such as 6MWT and TUG.
