Abstract

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.

Objetivo: Analizar la eficacia, en el cumplimiento terapéutico de la hipertensión arterial, de una intervención informativa mediante mensajes de alerta al teléfono móvil de hipertensos.

Diseño: Estudio comparativo, controlado, aleatorizado por grupos y multicéntrico.

Emplazamiento: Veintiséis consultas de atención primaria de España.

Participantes: Veintiséis investigadores aleatorizados a 2 grupos, que incluyeron a 104 hipertensos no controlados en monoterapia. Los investigadores se aleatorizaron al grupo control (GC) y al grupo de intervención (GI), compuestos ambos por 52 pacientes.

Intervención: Los pacientes GC recibieron la intervención habitual de su médico, y los pacientes GI recibieron mensajes de alerta al teléfono móvil 2 días a la semana durante 4 meses.

Mediciones principales: Se realizaron el recuento de comprimidos y la determinación de la presión arterial al inicio y a los 1, 3 y 6 meses. Se compararon los porcentajes de cumplidores, el porcentaje medio de cumplimiento y el grado de control de la hipertensión arterial. Se calculó la reducción del riesgo absoluto y relativo, así como el número de individuos en los que es necesario intervenir para evitar un incumplimiento.

Resultados: Fueron evaluables 67 individuos (34 individuos en GI y 33 en GC). Tuvieron un buen cumplimiento terapéutico el 85,1% (intervalo de confianza [IC], 74,9-95,3) en el GC, el 85,7% (IC, 70,5-100,9), y el 84,4% en el GI (IC, 70,7-95,3) (p = NS). El porcentaje medio ± desviación estándar de cumplimiento fue de 90,2 ± 16,3 globalmente (GC, 88,1 ± 20,8; GI, 91,9 ± 11,6; p = NS). El porcentaje de controlados al final fue del 51,5% (IC, 34,4-68,6) en el GC y del 64,7% (IC, 48,6-80,8) en el GI (p = NS).

Conclusiones: La intervención mediante mensajes de alerta al teléfono móvil de hipertensos no ha mejorado el cumplimiento terapéutico.
