A patient-entered computerized history, can be used as a means of medical data collection in a large inner city population. We evaluated whether a patient presenting to the Charity Hospital campus of the Medical Center of Louisiana in New Orleans would use a computer to provide medical information.
To determine whether patients would self-administer a computerized medical history and find this an acceptable experience
A survey questionnaire was given to 100 patients selected from the emergency department walk-in clinic waiting area.
Charity Hospital emergency room walk-in clinic
One hundred patients older than 18 years were selected to give a random sample of the population using the Charity Hospital emergency room walk-in clinic for care. The patients received a questionnaire for rating their experience with the computer. Demographics were collected for all patients, including the 13 who declined participation. The main outcome was the patient's perception of the acceptability of using the computerized medical history. A second important outcome measure was patient refusal to participate in the study.
Our analysis of the acceptability ratings revealed adequate internal validity (Cronbach alpha=0.75). A single total score was created for these ratings. The participants' scores ranged from 2.0 to 4.0, with a mean of 3.3 (standard error of the mean=0.04). We observed an 83% positive experience in the participating population.
The patients were able to use the computer to enter their medical information. They responded favorably to the experience and appeared to be capable and willing to provide medical information through use of this technology.
患者录入的计算机化病史可用作大城市市中心大量人群的医疗数据收集方式。我们评估了前往新奥尔良路易斯安那医学中心慈善医院院区就诊的患者是否会使用计算机来提供医疗信息。
确定患者是否会自行填写计算机化病史并认为这是一次可接受的体验。
向从急诊科随诊诊所候诊区挑选出的100名患者发放调查问卷。
慈善医院急诊室随诊诊所
挑选100名18岁以上的患者，以随机抽取使用慈善医院急诊室随诊诊所进行治疗的人群样本。患者收到一份用于评价其计算机使用体验的问卷。收集了所有患者的人口统计学信息，包括13名拒绝参与的患者。主要结果是患者对使用计算机化病史的可接受性的认知。第二个重要的结果指标是患者拒绝参与研究。
我们对可接受性评分的分析显示出足够的内部效度（克朗巴哈系数=0.75）。为这些评分创建了一个单一的总分。参与者的评分范围为2.0至4.0，平均分为3.3（均值标准误=0.04）。我们观察到参与人群中有83%的人有积极体验。
患者能够使用计算机录入他们的医疗信息。他们对这种体验反应良好，并且似乎有能力也愿意通过使用这项技术来提供医疗信息。
