ABSTRACT
Objective To discuss the effect of targeted information support on the sense of uncertainty and anxiety among patients treated with percutaneous coronary intervention and its instructive significance to nursing work.Methods We randomized 118 patients treated with percutaneous coronary intervention whose sense of uncertainty and anxiety were relative intensive into the test group and the control group with 59 cases in each group.We gave routine health instructions to the control group while targeted information support besides routine health instructions to the test group.We investigated the patients in two groups by Chinese version of uncertainty scale and State Anxiety Inventory at 4 time points,that is ,the first day in hospital,night before the operation,24 hours after the operation and 1 day before leaving hospital.Results The anxiety level and sense of uncertainty about illness decreased at the night before operation,24 hours after operation and 1 day after operation compared with the control group.The sense of uncertainty and anxiety level has statistical difference between whatever two adjacent time points except for anxiety level between the time points between the first day in hospital and before operation.Drop of sense of uncertainty at 24 hours after operation was significantly different between the two groups(P<0.01).Conclusion Supplying targeted information support could decrease the sense of uncertainty and anxiety among patients treated with percutaneous coronary intervention.
