This study aimed to evaluate the impact of a brief educational intervention delivered in cardiac rehabilitation (CR) on patients' knowledge of sublingual nitroglycerin (SLN).
Patients (n=86) commencing CR were provided with a brief educational intervention tailored to deficits identified in an assessment of SLN knowledge using the Sublingual Nitroglycerin Questionnaire, with reassessment at the end of program completion (6-8 weeks).
The mean age of patients was 64.95 years (standard deviation (SD) 10.87); 74% were male, 78% were married and 60% had not completed high school. Most (70%) had no prior coronary heart disease (CHD) history and 80% had been referred to CR following percutaneous coronary intervention. SLN knowledge scores increased from baseline to outcome. Patients were significantly more likely to know: the name of their SLN medication (11% increase, p=0.001), the recommended timing between doses (29% increase, p=0.02), the maximum number of doses (27% increase, p=0.005), to have SLN on their person at the time of the interview (25% increase, p<0.001) and to know the interaction between SLN and sildenafil (36% increase, p=0.001). The independent predictors of SLN knowledge included having better knowledge at baseline (β=0.28) and having consulted a general practitioner post discharge and before commencing CR (β=1.48).
A brief standardised knowledge intervention, individually tailored to identified deficits in a knowledge screen and delivered during CR, shows promise for improving patient knowledge of SLNs. The role of general practitioners in delivering medication education needs further investigation.
本研究旨在评估在心脏康复（CR）中实施简短教育干预对患者舌下硝酸甘油（SLN）知识的影响。
为开始 CR 的患者提供针对 SLN 知识评估中发现的缺陷量身定制的简短教育干预，在计划完成（6-8 周）结束时进行重新评估。
患者的平均年龄为 64.95 岁（标准差（SD）为 10.87）；74%为男性，78%已婚，60%未完成高中学业。大多数（70%）无先前的冠心病（CHD）病史，80%在经皮冠状动脉介入治疗后被转诊至 CR。SLN 知识评分从基线到结局均有所提高。患者更有可能知道：他们的 SLN 药物名称（增加 11%，p=0.001）、剂量之间的推荐时间（增加 29%，p=0.02）、最大剂量数（增加 27%，p=0.005）、在接受采访时身上带有 SLN（增加 25%，p<0.001）以及知道 SLN 与西地那非之间的相互作用（增加 36%，p=0.001）。SLN 知识的独立预测因素包括基线时知识更好（β=0.28）和出院后并在开始 CR 之前咨询过全科医生（β=1.48）。
在 CR 期间，针对知识筛查中发现的缺陷，提供简短的标准化知识干预措施，并根据个人需求进行定制，有望提高患者对 SLN 的知识水平。全科医生在提供药物教育方面的作用需要进一步研究。
