    ResumenObjetivoEstudiar la validez del registro del historial farmacoterap茅utico (HF) de la historia cl铆nica electr贸nica (HCE) comparado con el test de Morisky-Green en pacientes con tratamiento farmacol贸gico de la hipertensi贸n arterial.Dise帽oEstudio descriptivo transversal.EmplazamientoAtenci贸n Primaria.ParticipantesDoscientos cincuenta y dos pacientes con hipertensi贸n arterial en tratamiento farmacol贸gico, sin cambios de f谩rmacos o dosis, seleccionados aleatoriamente.Mediciones principalesSe estudiaron variables descriptivas, presi贸n arterial, proporci贸n de comprimidos retirados de las farmacias seg煤n el HF durante 12 meses respecto a los prescritos en la HCE (mala adherencia terap茅utica [AT] si era < 80%) y test de Morisky-Green. La validez del HF se estudi贸 mediante el 铆ndice Kappa, compar谩ndolo con el test de Morisky-Green (referencia) y el control de la presi贸n arterial.ResultadosLa edad media fue de 68 a帽os (50% de mujeres). Completaron el estudio el 77,4%. La mala AT fue del 51,3% por HF (IC 95% 44,3-58,3%) y del 15,4% (IC 95% 10,3-20,4%) con el test de Morisky-Green. El 铆ndice Kappa fue -0,068. Los pacientes con mala AT seg煤n el HF presentaron cifras m谩s elevadas de presi贸n arterial sist贸lica y diast贸lica (4,3 y 2,9 mmHg, respectivamente, p<0,05), sin diferencias en los pacientes con mala AT seg煤n el test de Morisky-Green (0,1 y 1 mmHg, respectivamente, p>0,05).ConclusionesLa mala AT seg煤n el HF es elevada y asociada al mal control de la hipertensi贸n arterial, de manera contraria al test de Morisky-Green. Estos resultados sugieren que el HF podr铆a ser 煤til para valorar la AT y que el test de Morisky-Green infraestima la mala AT.AbstractObjectiveTo study the validity of a prescription register (PR) incorporated into computerized medical records (CMR) compared with the Morisky-Green test in patients with high blood pressure using anti-hypertensive medication.DesignCross-sectional study.SettingPrimary Care.ParticipantsA total of 252 patients with hypertension using drug therapy with no changes in drugs or dosage were randomly selected.Main measurementsDescriptive variables, blood pressure, proportion of drug therapy collected from pharmacies according to the PR over 12 months compared with drug therapy prescribed in CMR (poor medication adherence [MA] if <80%), and Morisky-Green test. Validity of the PR was analysed using the Kappa index to compare PR with the Morisky-Green test (reference) and blood pressure levels.ResultsMean age was 68 years, 50% were women, and 77% completed the study. Poor MA was 51.3% according to the PR (95% CI 44.3%-58.3%) and 15.4% (95% CI; 10.3%-20.4%) when using the Morisky-Green test. The Kappa index was -0.068. Patients with poor MA according to the PR had higher levels of systolic and diastolic blood pressure (4.3 and 2.9 mmHg, respectively, P<0.05). No differences in blood pressure were observed in patients with poor MA if the Morisky-Green test was used (0.1 and 1 mmHg, respectively, P>0.05).ConclusionsPoor MA according to the PR is high and is associated with poorer control of blood pressure; the Morisky-Green test does not pick up on these differences. These results suggest that the PR could be useful for evaluating MA and that the Morisky-Green test underestimates poor MA
