Eficacia de una intervención informativa a hipertensos mediante mensajes de alerta en el teléfono móvil (HTA-ALERT)
Open accessAbstract
Objective To analyze the effect of an intervention to provide information with mobile phone text messages to patients with hypertension on compliance with therapy for hypertension.Design Comparative, controlled, multicenter, randomized cluster study.Setting 26 primary care health centers in Spain.Participants 26 researchers were randomized to a control group or an intervention group (52 patients each, for a total of 104 patients). All patients were receiving monotherapy for uncontrolled hypertension.Intervention Patients in the control group received their physician's usual interventions. Patients in the intervention group received messages and reminders sent to their mobile phones 2 days per week during 4 months.Main outcome measures Tablets were counted and blood pressure was measured at the start of the study and 1, 3, and 6 months later. The percentage of compliers, mean percentage of compliance and degree of control of hypertension were compared. The reduction in absolute and relative risk was calculated, as was the number of individuals needed to treat to avoid noncompliance.Results The results were evaluated for a total of 67 individuals (34 in the intervention group and 33 in the control group). The rate of compliance was 85.1% (CI, 74.9%-95.3%) overall, 85.7% (CI, 70.5%-100.9%) in the control group and 84.4% in the intervention group (CI, 70.7%-95.3%) (P=NS). Mean percentage compliance was 90.2%+/-16.3% overall, 88.1%+/-20.8% in the control group and 91.9%+/-11.6% in the intervention group (P=NS). The percentage of patients whose hypertension was controlled at the end of the study was 51.5% (CI, 34.4%-68.6%) in the control group and 64.7% (CI, 48.6%-80.8%) in the intervention group (P=NS).Conclusions The telephone messaging intervention with alerts and reminders sent to mobile phones did not improve compliance with therapy in patients with hypertension.

Results of other controlled trials indicate that SMS messages can help increase weight loss, physical activity and sunscreen use, as well as improve other outcomes.

From Impacts of e-health on the outcomes of care in low- and middle-income countries: where do we go from here? (2012) · cites this paper as [56]
The passage indexed under “Data availability” (page not specified) reports significantly greater weight loss in the SMS group, while cautioning that its cause and durability are uncertain. The intervention included exercise advice, but the paper does not report increased physical activity or address sunscreen use. Its “Qué aporta este estudio” section also says SMS did not demonstrably improve medication adherence. (LLM, conf=0.88)

Most mHealth studies have used text messages and notifications only.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
