Objetive: To evaluate the efficacy of an intervention by means of an educational magazine on treatment compliance in uncontrolled arterial hypertension (AHT).DesignControlled, randomised clinical trial.Setting87 primary care centres. Spain.ParticipantsA total of 450 patients with uncontrolled hypertension were included.InterventionTwo groups of 225 patients were formed: 1) Control group (CG): standard health intervention; 2) Intervention Group (IG): received a twice monthly educational magazine at home.Main measurementsCompliance was measured using the Medication Event Monitoring System (MEMS-Aardex). Compliance rate (CR) was recorded. Compliers were defined as individuals with a treatment compliance of 80–110%. The percentage of compliers, the mean percentage of doses taken and the percentage of patients taking the medication at the correct times were estimated. The mean blood pressures (BPs) and the percentage of controlled patientswere calculated. The number needed to treat (NNT) was calculated.ResultsA total of 393 individuals were evaluable (Age: 62.4 years), 196 in the IG and 197 in the CG. There were 83.2% (95% CI 78–88.4) and 49.2% (95% CI 42.2–56.2) (P=0.0001) of overall compliers in the IG and CG, respectively and 74% (95% CI: 67.9–80.1) and 42.6% (95% CI=35.7–49.5) (P=0.0001) of correct times compliers. A total of 81.6% (95% CI=76.2–86.5%)) were controlled in the IG and 56.3% (95% CI=49.4–63.2) in the CG. The NNT was 3.3 patients.ConclusionsTherapeutic non-compliance was very high.

[Control of therapeutic inertia in the treatment of arterial hypertension by using different strategies]. / El control de la inercia terapéutica en el tratamiento de la hipertensión arterial mediante diferentes estrategias.

OBJECTIVE: To evaluate the efficacy of different interventions on therapeutic Inertia (TI) in mild-to-moderate hypertension (AHT). DESIGN: Controlled, randomised clinical trial. SETTING: Two hundred clinics in 5 primary care centres. Spain. PARTICIPANTS: A total of 1104 patients with uncontrolled hypertension were included. INTERVENTION: Four groups with 276 patients were formed: 1) Control group (CG): standard health intervention; 2) Education intervention and a program of home blood pressure monitoring (HBPM) (EG); 3) Card control intervention and HBPM programme (CHG); 4) Education intervention, card control and HBPM programme (ECHG). MAIN MEASUREMENTS: TI was calculated by the rate: (Number of patients whose pharmacological treatment was not changed in each visit/Number of patients with an average BP 140mmHg and/or 90mmHg in the general population or 130 and/or 90 mmHg in diabetics). The mean BPs and the percentage of controlled patients were calculated. The mean number of people that required an intervention in order to avoid TI was calculated (NI). RESULTS: A total of 921 patients completed the study, and 1842 visits were made, with TI in 36.8% (IC=5.8%) of the sample and in 82.58% (IC=8.2%) of the uncontrolled hypertensive patients. The TI was 60% (CI=4.2%), 38.4% (CI=4.4%) 30.2 (CI=4.3%) and 14.7 (CI=3.3%) (p=0.001) for CG, EG, CHG and ECHG, respectively. The percentage controlled at the end of study was 35.3% (CI=1.1%), 54.7% (CI=1.8%), 60.2% (CI=2.1%) and 65.1% (CI=2.2%) (p<0.01) for CG, EG, CHG and ECHG, respectively. The NI were 4.6, 3.3 and 2.2 for CG, EG, CHG and ECHG, respectively. CONCLUSIONS: TI was very significant among the uncontrolled hypertensive patients. The studied interventions are effective for improving TI.

[Analysis of studies published on hypertension treatment non-compliance in Spain between 1984 and 2005]. / Análisis de los estudios publicados sobre el incumplimiento terapéutico en el tratamiento de la hipertensión arterial en España entre los años 1984 y 2005.

OBJECTIVE: To analyse therapy non-compliance in hypertension treatment in Spain, after a review of studies published between 1984 and 2005. DESIGN: Systematic review. DATA SOURCES: Data searches used Internet (Medline and Spanish index on doctoral these), a manual search of several Spanish journals, and bibliographic references to compliance from detected articles and through personal contact with experts. Descriptors used were: hypertension and patient compliance, compliance, adherence, patient drop-outs, treatment refusal, and their combinations. SELECTION OF STUDIES: Studies conducted in Spain and published between 1984 and 2005 were included, along with original articles, congress abstracts or doctoral theses, which used as a method of measurement pill count or counting of spaces in electronic monitoring systems, and which defined as non-compliers patients with a compliance percentage <80% and >110%. DATA EXTRACTION: The percentage of non-compliers was calculated, with 95% confidence intervals and weighted average of the percentage of non-compliers in each study. RESULTS: Twenty-six research studies published in Spain, excluding 2 analytical studies, were found. A total of 3553 patients with hypertension were included, of which 32.53% were non-compliers (n= 1156; 95 CI, 29.83-35.23) and 67.47% were compliers (n=2397; 95% CI, 65.67-69.27). The weighted average of non-compliance was at 32.78%. CONCLUSIONS: The percentage of therapy non-compliance in the treatment of hypertension in Spain has fallen in recent years, although it continues to be high.

Objetivos. Analizar el incumplimiento farmacológico de la hipertensión arterial (HTA) en España, a partir de una revisión de estudios publicados entre 1984 y 2005. Diseño. Revisión sistemática. Fuentes de datos. Se realizó una búsqueda mediante internet (Medline e índice español de tesis doctorales), búsqueda manual de diferentes revistas españolas y referencias bibliográficas de artículos detectados sobre cumplimiento y contacto personalizado de expertos. Los descriptores fueron: hypertension and patient compliance, or compliance, or adherence, or patient dropouts or treatment refusal y sus combinaciones. Selección de estudios. Se incluyen estudios publicados entre 1984-2005, como artículos originales, resúmenes de congresos o tesis doctorales, realizados en España y que utilizaran como método de medida el recuento de comprimidos o el de aberturas de los monitores electrónicos (MEMS) y haber definido a los incumplidores, con un porcentaje de cumplimiento 110%. Extracción de datos. Se calcularon el porcentaje de incumplidores y sus intervalos de confianza (IC) del 95%, y la media ponderada del porcentaje de incumplidores de cada estudio. Resultados. Se ha obtenido un total de 26 estudios de investigación publicados en España, excluyéndose 2 del análisis. El número total de pacientes incluidos ha sido de 3.553 hipertensos, con un 32,53% de incumplidores (n = 1.156; IC del 95%, 29,83-35,23) y un 67,47% de cumplidores (n = 2.397; IC del 95%, 65,67-69,27). La media ponderada del porcentaje de incumplimiento fue del 32,78%. Conclusiones. El porcentaje de incumplimiento en el tratamiento farmacológico de la HTA en España ha descendido en los últimos años, aunque sigue siendo elevado

Efficacy of telephone and mail intervention in patient compliance with antihypertensive drugs in hypertension. ETECUM-HTA study.

OBJECTIVE: To study the efficacy of telephone and mail intervention in therapeutic compliance among patients with mild to moderate hypertension. DESIGN: A prospective controlled multicenter clinical trial. SETTING: Eighty-five primary care centers in Spain, with a duration of 6 months. PATIENTS: A total of 636 patients with newly diagnosed or uncontrolled hypertension were included. Interventions. The patients were randomized and distributed between the following groups: (i) control (CG) - under routine clinical management; (ii) mail intervention (MIG) - received a mailed message reinforcing compliance and reminding of the visits (15 days, 2 and 4 months); (iii) telephone intervention (TIG) - received a telephone call at 15 days, then at 7 and 15 weeks. MAIN OUTCOME MEASURE: Five visits were scheduled, with the measurement of blood pressure and counting of tablets. Compliers were defined as subjects showing 80-110% drug consumption. Calculations were made of mean percentage compliance (MPC) and compliers, mean blood pressure and percentage controlled subjects. RESULTS: Five hundred and thirty-eight patients completed the study (261 males); 85.5% were compliers (CI = 82.5-88.5; n = 460). The MPC was 95.1+/-19.6% (CI = 93.28-96.92). The CG consisted of 182 individuals, MIG = 172 and TIG = 184. Compliers represented 69.2% of the CG (CI 62.5-75.9%), 91.3% (CI = 87.1-95.5) of the MIG (p = 0.0001) and 96.2% of the TIG (CI 93.5-98.9%); the final MPC was 89.6%+/-15 in CG, 96.6%+/-12 in MIG and 99.1+/-26.8 in TIG (p = 0.0001). The percentage of controlled subjects was 47.2% in CG (CI = 40-54.4), 61.3% in MIG (CI = 54.1-68.5%) and 63.3% in TIG (CI = 56.4-70.2%) (p<0.05). CONCLUSIONS: TIG and MIG are effective measures for improving patient compliance in hypertension.
