BACKGROUND: Emergency visits after colorectal surgery are common and require significant health care resources. However, many visits may be avoidable with alternative access to care. Mobile health technologies can facilitate patient access to health care providers. OBJECTIVE: We hypothesized that a mobile app for postdischarge monitoring with patient-provider communication ability would reduce emergency visits after elective abdominopelvic colorectal surgery. DESIGN: This is a prospective cohort study with a regression analysis after coarsened exact matching. SETTING: The study was conducted at a single colorectal referral center from May 2019 to September 2020. PATIENTS: A total of 114 patients were recruited to the intervention and were matched to a retrospective cohort of 608 patients from the 24 months before the study. All patients were managed according to an enhanced recovery pathway. INTERVENTIONS: A mobile phone app comprised of patient education material, daily questionnaires assessing postdischarge recovery, and patient-provider chat function was used. MAIN OUTCOME MEASURES: The primary outcomes included potentially preventable 30-day emergency visits defined according to a validated algorithm. Secondary outcomes included length of stay, complications, total emergency department visits, readmissions, and app usability. RESULTS: Coarsened-exact matching resulted in a matched sample of 94 prospective intervention patients and 256 retrospective control patients. The prospective group was associated with fewer preventable emergency department visits (incidence rate ratio 0.34; p = 0.043) and shorter length of stay (-1.62 days; p = 0.011). There were no differences in 30-day complications, total number of emergency visits, or readmissions. Patient-reported usability of the mobile app was high, with 88% of patients reporting that the app improved their ability to communicate with their surgeon. LIMITATIONS: We did not account for patient activation or perform a cost-analysis. CONCLUSION: Use of a mobile app was associated with fewer potentially preventable emergency visits and shorter length of stay after major elective colorectal surgery, which may be due to enhanced postdischarge monitoring and patient-provider communication.

APLICACIÓN DE TELÉFONO MÓVIL MEJORA LA COMUNICACIÓN ENTRE MÉDICO Y PACIENTE Y REDUCE LAS VISITAS AL DEPARTAMENTO DE EMERGENCIAS DESPUÉS DE CIRUGÍA COLORECTAL ANTECEDENTES: Las visitas de emergencia después de la cirugía colorrectal son frecuentes y requieren importantes recursos sanitarios. Sin embargo, muchas visitas pueden evitarse con un acceso alternativo a la atención. Las tecnologías de salud móviles pueden facilitar el acceso de los pacientes a los proveedores de atención médica. OBJETIVO: Se planteó la hipótesis de que una aplicación móvil para el seguimiento posterior al alta con capacidad de comunicación entre el paciente y el médico reduciría las visitas de emergencia después de cirugía colorrectal abdominopélvica electiva. DISEÑO: Este es un estudio de cohorte prospectivo con un análisis de regresión después de un emparejamiento exacto aproximado. ENTORNO CLINICO: El estudio se llevó a cabo en un solo centro de referencia colorrectal entre 05/2019 y 09/2020. PACIENTES: Se reclutó un total de 114 pacientes para la intervención y se emparejaron con una cohorte retrospectiva de 608 pacientes de los 24 meses anteriores al estudio. Todos los pacientes fueron tratados con protocolo de enhanced recovery. INTERVENCIONES: Se utilizó una aplicación para teléfono móvil compuesta de material educativo para el paciente, cuestionarios diarios que evalúan la recuperación posterior al alta y una función de chat entre el paciente y el médico. PRINCIPALES MEDIDAS DE RESULTADO: Los resultados primarios incluyeron visitas a la emergencia en 30 días potencialmente prevenibles, definidas según un algoritmo validado. Los resultados secundarios incluyeron la duración de la estancia, complicaciones, total de visitas al departamento de emergencias, reingresos y la usabilidad de la aplicación. RESULTADOS: El emparejamiento aproximado-exacto resultó en una muestra emparejada de 94 APP + y 256 APP-. APP + se asoció con menos visitas evitables al servicio de urgencias (IRR 0,34, p = 0,043) y una estancia más corta (-1,62 días, p = 0,011). No hubo diferencias en las complicaciones a los 30 días, número total de visitas de emergencia y reingresos. La usabilidad de la aplicación móvil informada por los pacientes fue alta, y el 88% de los pacientes informaron que la aplicación mejoró su capacidad para comunicarse con su cirujano. LIMITACIONES: No contabilizamos la activación del paciente ni realizamos un análisis de costos. CONCLUSIÓNES: El uso de una aplicación móvil se asoció con menos visitas a la emergencia potencialmente prevenibles y una estadía más corta después de una gran cirugía colorrectal electiva, lo que puede deberse a una mejor monitorización posterior al alta y a la comunicación entre el paciente y el médico.
