Effects of patient participation decision aid on decision conflict and risk perception of patients undergoing cardiac valve replacement / 中国实用护理杂志

Objective:To explore the effects of application of the patient participation decision aid in patients undergoing cardiac valve replacement.Methods:A total of 38 patients hospitalized for cardiac valve replacement from June to November, 2020 in the First Affiliated Hospital of Nanjing Medical University, were enrolled as the control group, and 38 patients admitted from January to May, 2020, were recruited as the experimental group by convenient sampling method. The control group was given routine nursing intervention, while the experimental group was carried out patient participation decision aid assistant program on the basis of routine nursing. The effects of intervention were assessed by Decision Conflict Sale (DCS), Preparation for Decision Making (PrepDM) and Risk Perception Questionnaire for patients with chronic diseases at admission and one day before operation.Results:There was no significant difference in the scores of DCS, PrepDM and Risk Perception Questionnaire for patients with chronic diseases at admission between the two groups( P>0.05). At one day before operation, the information& values scores dimension, support and valid decision dimension scores, decision uncertainty dimension scores and total scores of DCS were (12.37 ± 4.11) , (12.50 ± 4.65) , (3.74 ± 1.17), (28.61 ± 7.07) points in the experimental group, lower than those in the control group (15.11 ± 3.62) , (17.84 ± 4.25), (4.37 ± 1.30), (37.32 ± 6.57) points, the differences were statistically significant between the two groups( t values were 2.22-5.56, all P<0.05). At one day before operation, the score of PrepDM was (73.58 ± 5.32) points in the experimental group, higher than that in the control group (67.82 ± 4.89) points, the difference was statistically significant ( t=4.92, P<0.05). At one day before operation, the scores of economic risk dimension, physical and medical risk dimension, psychosocial risk dimension scores and total scores of Risk Perception Questionnaire for patients with chronic diseases were (11.45 ± 3.94), (12.39 ± 3.64), (7.21 ± 4.09), (31.05 ± 6.11) points in the experimental group, lower than those in the control group (13.50 ± 3.73), (15.82 ± 5.18), (9.32 ± 3.59), (38.63 ± 7.27) points, the differences were statistically significant ( t values were 2.33-4.92, all P<0.05). Conclusions:Patient participation decision aid program can effectively decrease decision conflict, promote preparation for decision making and alleviate risk perception of patients undergoing cardiac valve replacement.
