The current status and influential factors of uncertainty in illness in cardiac valvular surgery patients with cardiopulmonary bypass

Abstract

Objective To investigate the current status of uncertainty in illness in cardiac valvular surgery patients with cardiopulmonary bypass and analyze its influential factor, and provide reference for effective intervention. Methods A total of 208 cardiac valvular surgery patients with cardiopulmonary bypass were recruited from 4 cardiovascular surgery in Guangdong and were investigated with the self-designed questionnaire, Mishel Uncertainty in Illness Scale(MUIS), Connor-Davidson Resilience Scale (CD-RISC ), Medical Coping Modes Questionnaire(MCMQ), in the preoperative day and the day before discharge.The data were analyzed by single-factor and multiple-factor analysis. Results The average score of uncertainty in illness in cardiac valvular surgery patients with cardiopulmonary bypass was 99.09±11.41, and 92.3% of patients got a moderate uncertainty in illness level in the preoperative day.The average score of uncertainty in illness in the patients was 90.33±10.32, and 91.8% of patients got a moderate uncertainty in illness level in the day before discharge.Multiple linear regression indicated that, age, cardiac valvular disease types, number of cardiac valvular surgery, optimism and yield were the protective factors of uncertainty in illness level. Average monthly household income, self-improvement, scores of resilience and confront coping were the risk factors of uncertainty in illness level. Conclusion The level of uncertainty in illness in cardiac valvular surgery patients with cardiopulmonary bypass is moderate.Age, average monthly household income, cardiac valvular disease types, number of cardiac valvular surgery, resilience and coping style are factors influencing uncertainty in illness level of patients.
