Objective To evaluate the effect of clinical pathway in pulmonary thrombus embolism (PTE) .Methods 60 cases of PTE were admitted department of respiratory from 2011 to 2012 and divided into the experimental group and the control group ,30 cases for each group .The control group was implemented with normal process of hospital management while experimental group de-veloped clinical pathways .The efficacy ,department of respiratory drug costs ,complications and patient satisfaction were recorded and computed .Results The average department of respiratory and drug costs in experimental group respectively was (17 .13 ± 2 .22)days ,(16 545 .04 ± 1 557 .44) RMB and (7 050 .83 ± 372 .74) RMB ;less than (19 .77 ± 3 .41)day ,(17 709 .45 ± 1 902 .05) RMB and (7 345 .75 ± 450 .82) RMB in control group ,there were significant difference between the two groups (P<0 .05) .The satisfaction scores of experimental group and the control group respectively were (93 .47 ± 3 .88)sores and (90 .90 ± 5 .30)scores , there was significant difference between the two groups (P<0 .05) .The therapeutic effect and complication rates between experi-mental group and control group were no significant difference (P>0 .05) .Conclusion The effect of clinical pathway in PTE have a positive role in reducing hospitalization time ,total costs ,drug costs and increasing satisfaction ,it is worth to develop in primary hos-pital .
