To identify medicine information needs of patients and explore differences in information needs between different disease groups of patients.
Semistructured interviews with general medical patients selected via convenience sampling.
Patients were recruited while inpatients during a hospital stay or as outpatients attending a specific clinic at the hospital.
Patients' responses to standardised data-collection tools, including previously validated scale, the Extent of Information Desired scale (EID) to identify their information needs.
Data from interviews with 1717 patients were included in the analysis. Each item on the EID scale was scored on a Likert scale (from 1 to 5). The internal consistency of the scale in this sample was good (coefficient alpha = 0.78). Scores to the EID scale correlated with age and socio-demographic variables. The extent of information desired positively correlated with socio-economic status (Pearson's r = 0.29, p<0.001). The extent of information desired negatively correlated with the patient's age (Pearson's r = -0.32, p<0.001), implying that medicine-information desires decreases with age. Subsequently, significant differences were found in the extent of information desired between disease categories, which remained significant when controlling for age (ANCOVA, F(6,1703) = 26.04, p<0.001, partial eta2 0.084 (ie, 8.4% "effect size"). Disease categories included: cardiovascular, gastrointestinal, respiratory, endocrine, diabetic, oncology. Patients with endocrine and diabetes diagnoses expressed high desires for information, whereas patients with cardiovascular and respiratory diagnoses expressed low desires for information. From these findings, both the disease and the age of patient are principal influences on desires for medicine information.
These findings suggest that the diagnosis and disease have a significant bearing on patients' medicine-information desires and recommend that healthcare professionals view patients as individuals when providing information that meets their needs. It will be important for healthcare professionals to identify and understand that patients with different diseases have different desires for information about their disease and their drugs which may influence the way they take their medicines and subsequently the ways we manage their long-term disease. We need to determine if the EID scale is an efficient and effective way to identify patients' desires for drug information and a useful tool for practitioners to effectively target interventions in healthcare provision over time.
确定患者的医学信息需求，并探讨不同疾病组患者在信息需求上的差异。
通过便利抽样对普通内科患者进行半结构式访谈。
患者在住院期间作为住院患者或在医院特定门诊就诊时作为门诊患者被招募。
患者对标准化数据收集工具的反应，包括先前验证过的量表，即信息需求程度量表（EID），以确定他们的信息需求。
对1717名患者的访谈数据纳入分析。EID量表上的每个项目按李克特量表（从1到5）评分。该样本中量表的内部一致性良好（α系数 = 0.78）。EID量表得分与年龄和社会人口统计学变量相关。信息需求程度与社会经济地位呈正相关（皮尔逊相关系数r = 0.29，p < 0.001）。信息需求程度与患者年龄呈负相关（皮尔逊相关系数r = -0.32，p < 0.001），这意味着医学信息需求随年龄增长而降低。随后，发现疾病类别之间在信息需求程度上存在显著差异，在控制年龄后差异仍然显著（协方差分析，F(6,1703) = 26.04，p < 0.001，偏 eta2为0.084（即“效应量”为8.4%）。疾病类别包括：心血管疾病、胃肠道疾病、呼吸系统疾病、内分泌疾病、糖尿病、肿瘤。内分泌疾病和糖尿病诊断的患者对信息的需求较高，而心血管疾病和呼吸系统疾病诊断的患者对信息的需求较低。从这些发现来看，疾病和患者年龄都是影响医学信息需求的主要因素。
这些发现表明诊断和疾病对患者的医学信息需求有重大影响，并建议医疗保健专业人员在提供满足患者需求的信息时将患者视为个体。医疗保健专业人员识别并理解不同疾病的患者对其疾病和药物的信息有不同需求非常重要，这可能会影响他们服药的方式以及我们随后管理其长期疾病的方式。我们需要确定EID量表是否是识别患者对药物信息需求的有效方法，以及是否是从业者随着时间推移在医疗保健服务中有效进行针对性干预的有用工具。
