∗ Based on baseline assessment of intention to use the MOXXI system using the Technology Assessment Questionnaire. Physicians with ratings of 5 = extremely likely to use were categorized as high-intention-to-use physicians. Physicians who rated their intended use <5 were considered low-intention physicians. |
|
† At baseline, all physicians completed a standardized task that required them to write 3 prescriptions using the MOXXI system, retrieve a patient file, and enter a new health problem. The speed with which the physicians completed this standardized task was recorded in seconds. Physicians with the fastest speed in completing the standardized task were classified as being in the upper 50% of the distribution of speed in use of the application. |

‡ E-RX, and drug profile use is defined as the number of discrete patients per day for which the physician wrote a prescription using the E-RX pad, or accessed the drug profile divided by the number of visits made by eligible patients to the study physician in an outpatient or private clinic setting between January 2003 and January 2004. E-RX and drug profile use were retrieved from the audit trails recorded for MOXXI system use and the number of visits made by eligible patients was retrieved from the medical services claims file for the same time period. |
|
§ Annual practice size was defined as the number of unique patients seen between January 2003 and January 2004, prior to randomization. The number of unique patients seen was determined from the medical insurance number in all billings for medical services from an ambulatory clinic or outpatient setting within the time period. |
|
¶ Number of days worked was defined as the number of unique days that the physician billed for the delivery of patient services between January 2003 and January 2004, prior to randomization. The number of days worked was determined from medical services billing files using the date and location of service. |
|
∗∗ Mean number of patients per clinic day is defined as the cumulative number of patients seen in a outpatient or private clinic setting between January 2003 and January 2004, divided by the number of days worked in outpatient or private clinic setting within the same time period, based on data retrieved from medical services claims files. |
|
†† Number of different types of practice settings is defined as the number of different billing locations from which the study physician billed between January 2003 and January 2004 including emergency room, intensive care unit, inpatient, long-term care, outpatient clinic, private office, and other (e.g., prisons), based on data retrieved from medical services claims files. |
