Trial Outcomes & Findings for Patient Computer Dialog in Primary Care (NCT NCT00386776)
NCT ID: NCT00386776
Last Updated: 2013-06-20
Results Overview
The questionnaire consisted of 10 Likert scales questions assessing the computer-based history. The Likert scale ranged from 1 for 'Not at all' to 10 for 'Very'. We computed the mean of the responses to the question "How helpful were the questions when thinking about your health?" We also calculated a total score by averaging the mean scores of the 10 questions.

Participant Flow
We recruited patients from the Healthcare Associates (HCA)and the Affiliated Physicians Group (APG) clinics of Beth Israel Deaconess Medical Center who were to see their primary care physician for the first time.
Forty-five patients enrolled in the Computer-based medical history study. Forty of these patients started the medical history and 32 of these patients completed the program.

Computer-based Medical History
The intervention is a computer-based medical history designed for patients to take in their homes via the Internet. The history is divided into 24 modules- family history, social history, cardiac history, pulmonary history, and the like. So far as possible, it is designed to model the comprehensive, inclusive, general medical history traditionally taken, when time permits, by a primary care doctor seeing a patient for the first time. It contains 232 primary questions asked of all patients about the presence or absence of medical problems. Of these, 215 have the preformatted mutually exclusive responses

Experimental
n=40 Participants
The intervention is a computer-based medical interview, which contains 232 primary questions that are asked of all respondents, and over 6000 frames (questions, explanations, suggestions, recommendations, and words of encouragement) that are available for presentation as determined by the patient's responses and the branching logic of the program.

PRIMARY outcome
Timeframe: Immediately after taking the medical historyPopulation: We analyzed post medical history questionnaire responses for the 32 patients who completed the medical history patients.
The questionnaire consisted of 10 Likert scales questions assessing the computer-based history. The Likert scale ranged from 1 for 'Not at all' to 10 for 'Very'. We computed the mean of the responses to the question "How helpful were the questions when thinking about your health?" We also calculated a total score by averaging the mean scores of the 10 questions.

PRIMARY outcome
Timeframe: One day after the visit with the physicianPopulation: We analyzed post medical history questionnaire responses for the 23 patients who completed the medical history patients.
The questionnaire consisted of 6 Likert scales questions assessing helpfulness of the computer-based history for the patient at the time of the visit. The Likert scale ranged from 1 for 'Not at all helpful' to 10 for 'Very helpful'. We computed the mean of the responses to the question "How helpful was it for you to have taken the computer interview before seeing your doctor?" We also calculated a total score by averaging the mean scores of the 6 questions. In addition we calculated the combined mean of the responses of three of the patients whose doctors did not complete their post-visit questionnaire.

PRIMARY outcome
Timeframe: One day after the patient visitPopulation: We analyzed post visit physician questionnaire responses for the patients who completed the medical history and who showed up for their appointment.
The questionnaire consisted of 6 Likert scales questions assessing helpfulness of the computer-based history for the physician at the time of the patient visit. The Likert scale ranged from 1 for 'Not at all helpful' to 10 for 'Very helpful'. We computed the mean of the responses to the questions "How helpful was it for your patient to have taken the computer interview before seeing you?" " and the question "To what extent do you think the computer summary helped you to provide better care to your patient?" We also calculated a total score by averaging the mean scores of the 6 questions. In addition we calculated the combined mean of the physician responses to the post-visit questionnaires when physicians filled out the questionnaire but their patients did not.
