          Abstract

          Resumen Introducción: La falta de adherencia al tratamiento farmacológico es un problema prevalente y relevante en la evolución clínica. Objetivo: Evaluar el grado de adherencia al tratamiento intravenoso no antineoplásico de pacientes crónicos que acuden al hospital de día (HD), identificar los factores relacionados y analizar los desvíos de programación de la cita previa en el HD y su impacto en el Servicio de Farmacia (SF). Material y métodos: Estudio descriptivo longitudinal retrospectivo de tres años de duración (2017-2019) que incluyó a los pacientes que acudieron al HD a administrarse el tratamiento. Los datos de adherencia se extrajeron de los registros del SF y los datos demográficos-clínicos, de las historias clínicas electrónicas. El grado de adherencia se expresó enporcentaje (adherencia adecuada ≥90%). La asociación entre las variables y el grado de adherencia se estudió mediante test estadísticos de contraste de hipótesis. Resultados: Se incluyeron 300 pacientes, 60% mujeres, edad media 47 años. El 18% presentaron una adherencia inadecuada. La adherencia se asoció con la edad, el medicamento administrado, el intervalo posológico y la persistencia al tratamiento (p<0,05). El 5,6% del trabajo de HD se desvió de la programación suponiendo un trabajo adicional para el SF. Conclusiones: El grado de adherencia al tratamiento era inadecuado en casi una cuarta parte de la población. La edad, el medicamento infundido, el intervalo posológico y la persistencia al tratamiento se asociaron con la adherencia de los pacientes. Los desvíos en la programación de HD se tradujeron en trabajo sobreañadido para el SF.

          Abstract Introduction: The lack of adherence to pharmacological treatment of patients with chronic diseases it is a relevant problem. Objective: To assess the degree of adherence to the non-chemotherapy intravenous treatment of chronic patients who came to the outpatient clinic (OC), to identify the possible specific factors related to therapeutic compliance and to analyze the appointment changes in the OC and its impact on the Pharmacy Department (PD). Material and methods: Retrospective longitudinal descriptive study of three years duration (2017-2019). This included patients who went to the OC to receive the treatment. Adherence data were extracted from the PD records and demographic-clinical data from the review of electronic health records. Besides, the degree of adherence was expressed as a percentage (adherence adequate ≥90%). The association between the variables studied and the degree of adherence was estimated by means of statistical tests of hypothesis contrast. Results: A total sample size of 300 patients were included, mean age 47 years 60% women. Adherence of the treatment was inadequate in 18% of patients. The variables that showed a statistically significant association with adherence were the age, the drug delivered, the dosage interval and the persistence of treatment (p<0.05). 5.6% of OC work deviated from schedule and it meant additional work to the PD. Conclusions: The degree of adherence to the intravenous ambulatory treatment was inadequate in approximately a quarter of the population. The age, the infused drug, the dosage interval and the persistence of treatment were the variables that showed association with the adherence. Changes to OC programming resulted in over-added work for the PD.

          Medication adherence: its importance in cardiovascular outcomes.

          Medication adherence usually refers to whether patients take their medications as prescribed (eg, twice daily), as well as whether they continue to take a prescribed medication. Medication nonadherence is a growing concern to clinicians, healthcare systems, and other stakeholders (eg, payers) because of mounting evidence that it is prevalent and associated with adverse outcomes and higher costs of care. To date, measurement of patient medication adherence and use of interventions to improve adherence are rare in routine clinical practice. The goals of the present report are to address (1) different methods of measuring adherence, (2) the prevalence of medication nonadherence, (3) the association between nonadherence and outcomes, (4) the reasons for nonadherence, and finally, (5) interventions to improve medication adherence.

            Impact of medication adherence on hospitalization risk and healthcare cost.

            The objective of this study was to evaluate the impact of medication adherence on healthcare utilization and cost for 4 chronic conditions that are major drivers of drug spending: diabetes, hypertension, hypercholesterolemia, and congestive heart failure. The authors conducted a retrospective cohort observation of patients who were continuously enrolled in medical and prescription benefit plans from June 1997 through May 1999. Patients were identified for disease-specific analysis based on claims for outpatient, emergency room, or inpatient services during the first 12 months of the study. Using an integrated analysis of administrative claims data, medical and drug utilization were measured during the 12-month period after patient identification. Medication adherence was defined by days' supply of maintenance medications for each condition. The study consisted of a population-based sample of 137,277 patients under age 65. Disease-related and all-cause medical costs, drug costs, and hospitalization risk were measured. Using regression analysis, these measures were modeled at varying levels of medication adherence. For diabetes and hypercholesterolemia, a high level of medication adherence was associated with lower disease-related medical costs. For these conditions, higher medication costs were more than offset by medical cost reductions, producing a net reduction in overall healthcare costs. For diabetes, hypercholesterolemia, and hypertension, cost offsets were observed for all-cause medical costs at high levels of medication adherence. For all 4 conditions, hospitalization rates were significantly lower for patients with high medication adherence. For some chronic conditions, increased drug utilization can provide a net economic return when it is driven by improved adherence with guidelines-based therapy.
