Abstract
Objective To evaluate the efficacy and safety of self-management anticoagulation treatment for low pulmonary embolism severity index (PESI) outpatient with acute pulmonary embolism (APE).Methods Sixty-eight patients with APE of PESI grade Ⅰ-Ⅱ were divide into inpatient group and outpatient group with 34 cases each by random digits table.All the patients were treated with low molecular heparin followed by oral anticoagulation,and self-management was used in outpatient group.The efficacy was observed within 14 days and 3 months.The efficacy outcome included recurrent venous thromboembolism (VTE),standardization time of international normalized ratio (INR),VTE-related emergency department visit times,bleeding events and total mortality.Results There were 2 cases(5.9%,2/34) in inpatient group and 1 case (2.9%,1/34) in outpatient group with recurrent VTE,and there was no statistical significance between two groups (P > 0.05).Standardization time of INR in inpatient group [(8.5 ± 2.9) d] was shorter than that in outpatient group [(16.1 ± 4.4) d],and there was significant difference (P< 0.01).There was no significant difference in the VTE-related emergency department visit times between two groups (P > 0.05).There was 1 case with major bleeding and 1 death respectively in outpatient group.Conclusion It is effective and safe to give early self-management anticoagulation treatment to APE patients with PESI grade Ⅰ-Ⅱ,which could shorten time spending in hospital and release burden both physically and mentally.
