Abstract:
Objective To observe the effect of out-hospital standardized treatment on the recurrence of the first onset of acute unprovoked pulmonary thromboembolism (PE) after discontinued anticoagulant therapy or during anticoagulation therapy in PE patients after treatment and discharged from hospital.Methods A prospective study of patients with acute PE admitted into emergency ICU for training in out-hospital standardized anticoagulation treatment was carried out from January 2015 to December 2016 (observation group).Another cohort of EP patients without training in out-hospital standardized anticoagulation treatment admitted from January 2010 to December 2014 was enrolled for retrospective analysis(control group).The out-hospital standardized anticoagulation treatment strategy included the guidance of anticoagulation therapy,record all of the patients' symptoms related with recurrent EP both during and discontinuous anticoagulant treatment,V/O scan at 3 months,6 months and 12 months follow-up,respectively.The patients with ceased anticoagulant therapy would be followed up for at least one year.Patients with signs of recurrence would have a definite diagnosis at once.The anticoagulation status and outcome of the patients in control group found in out-patient department were recorded.Results ① There were 129 patients with acute unprovoked PE in observation group and 246 in control grouThere were no significance difference both in mean age and gender between two groups (P ＜0.05).② Recurrence rate was 11.63％ in observation group and 22.36％ in control group (P ＜0.01);③ There was significance difference in mortality rate between observation group (3.1％) and control group (10.85％) (P ＜0.05).There was also significant difference in rate of missing follow-up between observation group (10.85％) and control group (21.54％) (P＜0.001),and.there was significant difference in rate of discontinuous anticoagulation therapy between observation group (1.55％) and control group (8.5％) (P ＜0.01).④ There was no significance difference seen in the rate of patients exposed to multiple risk factors of arteriosclerosis between observation group (82.25％) and control group (77.64％) (P＜0.05).But the target rate of controlling various risk factors of arteriosclerosis was 79.31％ in observation group and 54.97％ in control group respectively (P＜0.05).Conclusions Standardized treatment can effectively reduce the recurrent rate of the venous episodes of the patients with first episode of acute unprovoked pulmonary thromboembolism;Recurrent venous episodes of the PE patients who exposed to the multiple risk factors of arteriosclerosis require more attentions.
