RESUMEN

Objetivo:

el objetivo de este estudio fue describir y analizar los patrones de prescripción de fármacos antiulcerosos, los factores asociados a su prescripción y su costo en pacientes ambulatorios polimedicados en un período de 6 meses, en una Entidad Promotora de Salud (EPS) colombiana a nivel nacional.

Metodología:

estudio descriptivo retrospectivo de corte transversal, basado en registros electrónicos de prescripción de medicamentos ambulatorios de 2 458 447 afiliados. Se incluyeron pacientes con prescripción de 5 o más fármacos por mes y se excluyeron aquellos cuyos registros transaccionales no tenían información completa para su análisis. Se evaluó la asociación entre prescripción de fármacos antiulcerosos y factores que justifican su prescripción mediante los odds ratio (OR) calculados a partir de un modelo de regresión logística.

Resultados:

de 2 458 447 afiliados, 60 671 pacientes estuvieron polimedicados mensualmente; 40% tuvieron fármacos antiulcerosos y 70% fármacos gastrolesivos. De los gastroprotegidos, 47% fueron adultos mayores y 12% tuvieron asociado diagnóstico de riesgo gastrointestinal superior. Gastroprotección no justificada en 35% de los pacientes polimedicados, representando $75 millones de pesos colombianos (COP) mensuales. No hubo asociación estadística entre la prescripción de antiulcerosos y factores que justifiquen su prescripción (OR 1,13; IC 95% 1,00-1,27).

Conclusión:

ante la falta de asociación entre la prescripción de fármacos antiulcerosos y los factores que la justifican, es probable que su prescripción se haya realizado por la polifarmacia per se. Se recomienda optimizar la gastroprotección y reservarla a pacientes con más de un gastrolesivo y riesgo gastrointestinal superior, estén estos polimedicados o no.
ABSTRACT

Objective:

The objective of this study was to describe and analyze patterns of use of prescription ulcer drugs, factors associated with prescriptions by physicians, and costs for outpatients With polypharmacy at a Colombian healthcare promotion entity (EPS) over a six-month period.

Methodology:

This is a retrospective and descriptive cross-sectional study based on electronic records of drugs prescribed to 2,458,447 outpatient members. Patients who took five or more prescription drugs per month were included. Patient were excluded if their records in the transactional data were not complete enough for analysis. Associations between anti-ulcer drugs and factors justifying their prescription were evaluated by the odds ratio (OR) which was calculated from a logistic regression model.

Results:

Of the 2,458,447 affiliates of the EPS, on average 60,671 patients had polypharmacy each month 40% used anti-ulcer drugs and 70% used gastro-damaging drugs. Of the gastroprotected patients, 47% were elderly and 12% had associated diagnoses of upper gastrointestinal risk. Gastroprotection was not justified in 35% of patients with polypharmacy. This represents 75 million Colombian pesos every month. There was no statistical association between prescription of anti-ulcer drugs and factors that justify their prescription (OR 1.13; 95% CI 1.00 to 1.27).

Conclusion:

Given the lack of association between prescription of anti-ulcer drugs and factors which justify such prescriptions, it is likely that prescriptions contribute to polypharmacy per se. We recommended optimizing gastroprotection by reserving it for patients with more than one gastrointestinal lesion and with upper gastrointestinal risks whether or not they have polypharmacy.
