Abstract
Introduction

The treatment aims to achieve symptomatic remission, normalization of biomarkers such a fecal calprotectin, and endoscopic remission. Therefore, early recognition of inflammatory activity and timely therapeutic intervention are essential to improve the morbidity and mortality.

Objective

Evaluate the adherence among gastroenterologists and the patients compliance with medical recommendations in the Inflammatory Bowel Disease Program at Clínica Universidad de los Andes.

Patients and methods

A retrospective study that included patients presenting with a flare confirmed by colonoscopy. Three follow-up stages were defined: Short-Term Control: symptomatic remission at 3 months, Medium-Term Control remission of fecal calprotectin as a biomarker (<250 µg/g) between 4 and 6 months, and Long-Term Control: endoscopic remission between 6 and 9 months.

Results

A total of 104 patients were evaluated, 64% of the cohort were females and a median age of 41 years. Among them, 81% had Crohn&apos;s disease, with an inflammatory phenotype in 87% and colonic localization in 39%. The remaining 19% had ulcerative colitis with left-sided involvement in 50%. Ninety percent of the patients attended short term control with a symptomatic remission in 72%. Eighty-two percent attended medium term control, resulting in biomarker remission for 83% of them. Seventy seven percent attended long term control, achieving endoscopic remission in 59% of the cases.

Conclusion

The results indicate that our Program achieves a physician adherence of over 90% to STRIDE II, with patient’s adherence to pharmacological therapy and follow up above 70%. Although these are high percentages, they are subject to improvement.

Resumen
Introducción

El tratamiento por objetivos busca lograr remisión sintomática, normalización de biomarcadores como calprotectina fecal; y remisión endoscópica en plazos definidos. El reconocimiento precoz de la actividad inflamatoria e intervención terapéutica oportuna, son fundamentales para mejorar la morbimortalidad.

Objetivo

Evaluar adherencia de médicos gastroenterólogos y el cumplimiento a las indicaciones de los pacientes del Programa de Enfermedad Inflamatoria Intestinal de la Clínica Universidad de los Andes.

Paciente y métodos

Estudio retrospectivo, incluyó pacientes con brote de actividad confirmada mediante colonoscopia. Se definieron tres etapas: Control Corto Plazo: remisión sintomática a los 3 meses, Control Mediano Plazo: remisión de calprotectina fecal (<250 µg/g) entre los 4 y 6 meses, y Control Largo Plazo: remisión endoscópica entre el 6-9 mes.

Resultados

Se evaluaron 104 pacientes, con 64% de sexo femenino y mediana de edad de 41 años. El 81% presenta enfermedad de Crohn, fenotipo inflamatorio (87%) y localización colónica (39%). El 19% corresponde a colitis ulcerosa, compromiso izquierdo en el 50%. El 90 % asistió al control a corto plazo, logrando remisión sintomática en el 72%. El 82% de acudió al control mediano plazo, logrando remisión de calprotectina fecal en el 83%. El 77% de los pacientes asistió al control largo plazo, con remisión endoscópica en el 59% de los casos.

Conclusión

Los resultados indican que nuestro programa logra adherencia del 90% de los médicos a pautas STRIDE-II. En los pacientes, la adherencia a la terapia y al seguimiento esta sobre 70%. Aunque los porcentajes son elevados,permiten una oportunidad de mejora.
