Hospital vs. Cell Phone Number Follow-Up Randomization Study

Not Applicable

Completed

• Conditions: Subject Follow-up
• Interventions: Other: Hospital Landline Phone Calls; Other: Private Cell Phone Calls

• Registration Number: NCT01620827
• Lead Sponsor: University of Pennsylvania

Brief Summary

This study is being conducted to evaluate the hypothesis that study subjects will be more responsive to follow-up phone calls made from personal cell phone numbers than from hospital landline numbers. To evaluate this, study subjects previously enrolled in a cardiac biomarker study (the Early Identification of Acute Coronary Syndrome study) were randomized to receive their follow-up phone calls (the calls associated with the Early ID study occur at 30 days and 1 year after initial enrollment) from either a hospital office landline or from the personal cell phones of the research assistants making these calls. This was done as a 1:1 randomization. The number of call attempts required to reach the study subjects were recorded as the calls were made and the date of successful follow-up was recorded once contact was made.

Arm && Interventions

Group	Intervention	Description
Hospital Landline	Hospital Landline Phone Calls	Subjects in this arm have all of their follow-up phone calls placed from a hospital landline number.
Private Cell Phone	Private Cell Phone Calls	Subjects in this arm have all of their follow-up phone calls placed from a private cell phone number.

Primary Outcome Measures

Name	Time	Method
Successful phone call contact at 30 days	90 days	Contact is attempted from 30 days after enrollment through 90 days after enrollment. If contact is made during this time frame, 30 day follow-up is considered to have been successful.

Secondary Outcome Measures

Name	Time	Method
The number of call attempts required to obtain successful follow-up	90 days	Contact is attempted from 30 days after enrollment through 90 days after enrollment. The number of calls required to make successful contact in this time frame are recorded.
