目的 探讨冠脉介入治疗术(PCI)后患者的疾病感知与服药依从性的相关性.方法 采用便利取样的方法,选取2011年8-12月在广州市某三甲医院心内科门诊随访的PCI术后患者作为研究对象.共纳入95例,采用疾病感知问卷修订版、服药依从性问卷对其进行问卷调查.结果 (1)PCI术后患者疾病感知状况:症状识别平均(4.87±3.50)分；病情认知各维度平均得分由高到低依次是:病程(3.68±1.10)分、个人控制(3.59±0.83)分、治疗控制(3.54±0.65)分、疾病一致性(3.02±1.04)分、后果(2.79±0.87)分、情感陈述(2.24±0.86)分、周期性(1.92±1.06)分；疾病归因部分得分最高的是食物或进食习惯(3.35±1.83)分.(2)PCI术后患者服药依从性总分平均为(14.52±1.99)分,完全依从率为35.8％.(3)PCI术后患者的症状识别与服药依从性总分呈正相关(r=0.203,P＜0.05)；个人控制维度(r=-0.236,P＜0.05)及情感陈述维度(r=-0.228,P＜0.05)分别与服药依从性呈负相关.结论 医护人员应提高PCI术后患者的症状识别能力,强调遵医嘱服药的重要性,及时疏导不良情绪,从而提高其服药依从性.

Objective To explore the relationship between illness perceptions and medication adherence of patients undergoing percutaneous coronary intervention (PCI).Methods The Illness Perception Questionnaire-Revised(IPQ-R) and Medication Adherence Questionnaire were used to investigate 95 patients undergoing PCI.Results (1)Illness perception status of patients undergoing PCI:average score of identity was (4.87 ± 3.50).Subscales of illness representation were listed according to scores from high to low as follows:timeline (acute/chronic) (3.68 ± 1.1 0),personal control (3.59 ± 0.83),treatment control (3.54 ± 0.65),illness coherence (3.02 ± 1.04),consequences (2.79 ± 0.87),emotional representation (2.24 ± 0.86),timeline cyclical (1.92 ± 1.06).In the part of causes,diet or eating habit scored highest (3.35 ± 1.83).(2)The average total score of medication adherence of patients undergoing PCI was (14.52 ± 1.99) and rate of complete adherence was 35.8％.(3) Identity of patients undergoing PCI was positively correlated with medication adherence (r =0.203,P ＜ 0.05).And personal control (r =-0.236,P ＜ 0.05) and emotional representation (r =-0.228,P ＜ 0.05) were negatively correlated with medication adherence.Conclusions Health care workers should improve symptom identity of patients undergoing PCI,emphasize the importance of adherence to medication,and help them relieve negative emotion in time to enhance their medication adherence.
