Short Message Service (SMS) e promoção do autocuidado em DM2: revisão integrativa

Implementation of a text messaging intervention to patients on warfarin therapy in Brazilian primary care units: a quasi-experimental study

Background

Warfarin remains the most affordable oral anticoagulant in many countries. However, it may have serious side effects, and the success of the therapy depends on the patient’s understanding of the medication and their adherence to treatment. The use of short messages services (SMS) is a strategy that can be used to educate patients, but there are no studies evaluating this intervention in patients taking warfarin. Therefore, we aimed to develop, implement, and assess the feasibility of an intervention using SMS to primary care patients taking warfarin in a medium-sized Brazilian city.

Methods

A bank of 79 SMS was drafted and validated by an expert panel. During 6 months, three times a week, patients received messages about anticoagulation with warfarin. At baseline and after 3 months, we assessed their knowledge and adherence with validated instruments. At the end of the follow-up, participants answered a satisfaction questionnaire. Subsequently, a scale-up phase was conducted, with another round of the intervention including 82 participants (29 from the first phase and 53 newly recruited). Seven months after the end of the scale-up, we asked the patients for their insights about the long-term effects of this program. All patients signed informed consent. The study was approved by the Research and Ethics committee of the Universidade Federal de Minas Gerais.

Results

In the pilot, 33 (89.2%) patients completed the follow-up. Among the participants who answered the satisfaction questionnaire (n = 29), 86.2% considered that the intervention motivated a healthy lifestyle and improved their understanding of warfarin therapy. All patients were willing to continue receiving the messages. Adherence measured by the Measure of Adherence to Treatment (MAT) test was high in the pre-intervention assessment and remained high (96.7% vs. 93.3%; p = 1.0000). The proportion of patients who achieved > 75% correct answers on the Oral Anticoagulation Knowledge (OAK) test increased from 6.5% to 25.6, p = 0.0703. In the scale-up, 23 patients answered the long-term assessment questionnaire. The main long-term knowledge reported was dietary information. Nine patients received the messages but did not remember their content.

Conclusion

The intervention was well-accepted and had a positive impact on patient’s knowledge about oral anticoagulation therapy. The scale-up assessment reinforced the need to constantly monitor digital interventions.

Effectiveness of theory-based Multimedia Messaging Service (MMS) on exercise benefits and barriers among patients with type 2 diabetes

The current study aimed to examine the effectiveness of multimedia messaging service (MMS) education on exercise benefits and barriers in patients with type 2 diabetes. A quasi-experimental, pretest-post-test design recruited 98 patients with type 2 diabetes. The intervention group received MMS education to improve perceived exercise benefits and decrease exercise barriers over two months, and the control group received routine care. All patients completed a survey at three time points (baseline, 4 and 8 weeks post-intervention). The results showed that there was an improvement in both perceived life enhancement and physical performance domains in the intervention group. The exercise context barriers decreased after the first follow-up but increased during the second follow-up in the intervention group. Cohen's d values indicated a medium effect size in life enhancement (0.502) and physical performance (0.525) subscales. A small effect size was found in psychological outlook (0.196) and exercise context (0.132) subscales. However, there was no significant effect of the intervention in time expenditure (-0.244) and physical exertion (-0.119) subscales. In conclusion, theoretically based MMS health education targeting perceived exercise benefits and barriers was feasible and cost-effective in changing patients with diabetes' perceptions and intended behaviors about regular physical activity.

Effect of Multimedia Messaging Service on Exercise Self-efficacy in Diabetic Patients

Objectives: To increase patients' self-efficacy for initiation of physical activity, there is a need to include physical activity into patient education in clinic settings. In this study, we aimed to assess the effectiveness of multimedia messaging service (MMS) education on exercise self-efficacy in patients with type 2 diabetes mellitus (T2DM). Methods: We used a quasi-experimental, pretest-posttest design to study 98 patients with T2DM. The intervention group received MMS education targeting exercise self-efficacy for 2 months, and the control group received routine care only. Patients in both groups completed the Exercise Self-efficacy scale at 3 stages (at baseline, at 4 weeks, and at 8 weeks post-intervention). Results: We found a slight increase between baseline, first follow-up, and second follow-up in interpersonal and competing demands factors in the intervention group (p = .002, p = .001, respectively), but no improvement in the control group in any of the 3 factors over time (p > .05). Also, Cohen's d values indicated a medium effect size in all exercise self-efficacy subscales (interpersonal [0.734], competing demands [0.665], and internal feelings [0.696]). Conclusions: Health education using theoretically-based MMS targeting exercise self-efficacy was effective and affordable in promoting and changing patients' beliefs and physical activity behaviors.

Educating diabetic patients through an SMS intervention: a randomized controlled trial at a Brazilian public hospital

Objective

Diabetes mellitus (DM) has a high healthcare system cost worldwide. Educational strategies are important to improve self-care and control this disease. This study aimed to evaluate satisfaction and clinical efficacy of a Short Message Service (SMS) educational intervention in self-care and nutrition at a Brazilian university hospital.

Methods

We conducted a trial of educational intervention and assigned eligible patients with DM to either receive weekly educational SMS for 6 months (intervention group [IG]) or no SMS at all (control group). A satisfaction questionnaire was applied before and after the intervention in both groups. Laboratory (fasting glucose, hemoglobin [Hb] A1c, total cholesterol, triglycerides, high-density lipoprotein, and low-density lipoprotein) and clinical (blood pressure) data were also collected. Data were analyzed using nonparametric tests with the Statistical Package for the Social Sciences.

Results

We included 128 patients (64 in each group). Responses to the satisfaction questionnaire with self-care and healthcare professionals from 112 patients revealed an improvement in the perception of receiving information regarding helpful eating habits and in healthy eating behavior and an improvement in satisfaction with their diabetes care in the IG. In the post-intervention period, improved systolic blood pressure and HbA1c levels were observed in the IG as illustrated by delta % (post-intervention minus pre-intervention data divided by pre-intervention data multiplied by 100) reductions of 2.3% and 3.9%, respectively.

Conclusion

SMS intervention was useful as an educational tool for improving satisfaction and glycemic and blood pressure control of patients with DM observed at a Brazilian university hospital.

An Umbrella Review of Text Message Programs for Adults With Type 2 Diabetes

Purpose

The purpose of this umbrella review was to synthesize the evidence from published systematic reviews on the effectiveness of text message programs for adults with type 2 diabetes (T2DM) on glycemic management (A1C), self-management, and other clinical outcomes. The effect of directionality of the program was also explored.

Methods

A systematic search was conducted using multiple databases. Inclusion criteria were systematic review of text message programs for adults with T2DM, evaluated A1C, and English language. Quality assessment was completed using AMSTAR-2 guidelines. Data were extracted by multiple coders, and results were synthesized.

Results

The final sample included 9 systematic reviews published between 2011 and 2019, with 72 unique international studies. Text message programs focused on diabetes self-management and reducing health risks through educational and motivational content with some providing personalized feedback. A meta-analysis of program effect on A1C was conducted in 5 reviews with a pooled difference in A1C from −0.38% to −0.8%. Adults with T2DM of shorter duration and lower A1C had better treatment effects. Evidence on unidirectional versus bidirectional programs is conflicting; however, both improve outcomes. Evidence of text message programs targeting medication engagement was inconclusive. Some programs improved blood pressure, lipids, self-management, self-efficacy, and health behaviors. High satisfaction and an average of 9.6% to 18.7% attrition was reported.

Conclusions

Text messaging programs can improve T2DM outcomes, are a highly accessible mode of communication, are relatively inexpensive, and are an underutilized adjunct to clinical care.
