  Purpose
The investigators will study the efficacy of a novel cellular phone messaging system to communicate health information and facilitate early return to clinic after abnormal laboratory results in rural Uganda.

Condition Intervention
HIV Tuberculosis Other: Cellular Phone Text Messages

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Intervention Model Description:

This is a quasi-experimental design study with two periods of study. The pre-intervention period serves as the control group. During the intervention period, participants were randomized into one of three message types to be informed of their test results: 1) a standard message informing their abnormal result, 2) the standard message protected by a PIN number code, and 3) a coded texted message "ABCDEFG."

For our a priori hypotheses about the effect of receiving an SMS message on outcomes, we compared results for participants in the pre-intervention period with all those in the post-intervention period. This was a non-randomized, sequentially allocated intervention.In secondary analyses, we compared results within the randomized sub-groups.

For our primary outcome (time to clinic return) we assessed all participants with abnormal CD4 count results. For our secondary outcome (time to ART initiation) we looked at a subgroup of participants who were ART-naive.

Primary Outcome Measures:
  • Participants Initiating Antiretroviral Therapy (ART) Within 28 Days of Abnormal Result [ Time Frame: 28 days ]
    Number of Antiretroviral Therapy (ART) naive participants (subgroup of the sample) who initiated ART within 28 days of receiving abnormal result


Secondary Outcome Measures:
  • Clinic Return Within 28 Days of Abnormal CD4 Count Result [ Time Frame: 28 days ]
    Number of participants who returned to clinic within 28 days of abnormal CD4 count result


Enrollment: 183
Study Start Date: July 2012
Study Completion Date: April 2015
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Direct Text Message
Participants in the intervention period (September 2012 - November 2013) received daily short message service (SMS) messages for up to seven days with messages reporting an abnormal result
Other: Cellular Phone Text Messages
Cellular phone text message formats to be sent to participants after abnormal laboratory results to communicate information and request early return to clinic.
No Intervention: Pre-Intervention
Participants enrolled in the pre-intervention period (January - August 2012) served as a control group.

Detailed Description:

Among the challenges that complicate optimal health care delivery in rural settings is lack of communication between care providers and patients. Communication of abnormal laboratory results represents a particular challenge. Laboratory and other test results are often not reported until repeat visits weeks to months later. In the case of treatment failure, severe treatment complications, or evidence of opportunistic infection, such reporting delays likely result in adverse outcomes and potentially compromise future treatment options. The investigators propose to evaluate a novel strategy of communication using SMS text messaging to facilitate patient return to an HIV clinic in Uganda after critical laboratory results.

The investigators will consent and enroll participants at the time of laboratory testing for cluster of differentiation 4 (CD4) count, viral loads, acid fast bacteria smears of sputum, among others. Those with abnormal results will be randomized to various messaging formats and receive text messages requesting a prompt return to clinic. For outcomes, the investigators will measure successful receipt and comprehension of messages, as well as proportion returning within 14 days of the abnormal laboratory test.
