Text messaging improves diabetes-related knowledge of patients in India: A quasi-experimental study

Background. Diabetes-related health education promotes patient efficacy for diabetes self-management. However, sub-optimal knowledge of diabetes in people with diabetes is recognized as a challenge in overcrowded public health facilities in India. We aimed to determine the effect of health education through mobile phone text messages (short messaging service [SMS]) on diabetes-related knowledge of patients with diabetes. Methods. From February 2016 to February 2017, we recruited adult patients with diabetes for this quasi-experimental study done in the outpatient setting of a major tertiary care government hospital in Delhi, India. Participants in the intervention group received a text message on diabetes self-care practices every alternate day for 90 days. We evaluated the patients’ knowledge of diabetes using the Spoken Knowledge in Low Literacy in Diabetes (SKILL-D) questionnaire and a self-designed diabetes knowledge questionnaire. Results. We enrolled 190 men and 160 women, of whom 52 (13.7%) were lost to follow-up. At baseline, mean diabetes knowledge scores were higher in the intervention group compared to the control group. After the intervention period of 3 months, the diabetes knowledge scores for SKILL-D and the patient diabetes knowledge questionnaire showed a statistically significant increase in the intervention group (mean difference 0.7 and 0.5, respectively; p<0.001, but there was no increase in the control group). Conclusion. The use of mobile phone technology for diabetes-related health education through mobile text-message (SMS) technology is an effective method for health promotion.
