ABSTRACT
Background: Previously published retrospective series show a high prevalence of fecal incontinence (FI) in stroke patients. We aimed to analyze in a prospective series the current incidence of FI in acute stroke in functionally independent patients and its evolution over time and the patient characteristics associated with the appearance of FI in acute stroke. Methods: We included consecutive patients with acute stroke admitted in our stroke unit who fulfilled the following inclusion criteria: a first episode of stroke, aged >18 years, with no previous functional dependency [modified Rankin Scale (mRS) ≤ 2] and without previous known FI. FI was assessed by a multidisciplinary trained team using dedicated questionnaires at 72 ± 24 h (acute phase) and at 90 ± 15 days (chronic phase). Demographic, medical history, clinical and stroke features, mortality, and mRS at 7 days were collected. Results: Three hundred fifty-nine (48.3%) of 749 patients (mean age 65.9 ± 10, 64% male, 84.1% ischemic) fulfilled the inclusion criteria and were prospectively included during a 20-month period. FI was identified in 23 patients (6.4%) at 72 ± 24 h and in 7 (1.9%) at 90 days ± 15 days after stroke onset. FI was more frequent in hemorrhagic strokes (18 vs. 5%, p 0.007) and in more severe strokes [median National Institute of Health Stroke Scale (NIHSS) 18 (14-22) vs. 5 (3-13), p < 0.0001]. No differences were found regarding age, sex, vascular risk factors, or other comorbidities, or affected hemisphere. Patients with NIHSS ≥12 (AUC 0.81, 95% CI 0.71 to 0.89) had a 17-fold increase for the risk of FI (OR 16.9, IC 95% 4.7-60.1) adjusted for covariates. Conclusions: At present, the incidence of FI in acute stroke patients without previous functional dependency is lower than expected, with an association of a more severe and hemorrhagic stroke. Due to its impact on the quality of life, it is necessary to deepen the knowledge of the underlying mechanisms to address therapeutic strategies.
ABSTRACT
OBJETIVOS: Determinar la sensibilidad de detección de ictus por parte de los servicios de emergencias médicas (SEM) y analizar las características clínicas de los pacientes con sospecha de ictus no identificados. PACIENTES Y MÉTODOS: Registro prospectivo de pacientes con sospecha de ictus de nuestra área (850.000 habitantes) desde 2011 hasta 2017. Se seleccionó a la población que avisó al SEM. De ésta, se compararon los pacientes con y sin activación de código ictus por parte del SEM (SEM+ frente a SEM-). Se registraron los datos demográficos, el tiempo de evolución, las características clínicas del episodio y el tratamiento de reperfusión administrado. RESULTADOS: De un total de 5.497 pacientes con sospecha de ictus, 2.087 alertaron al SEM: 1.611 (77%) SEM+ y 476 (33%) SEM-. Los pacientes SEM- presentaron menor puntuación en la National Institute of Health Stroke Scale (8 frente a 11) y mayor frecuencia de clínica de territorio vertebrobasilar (14,1% frente a 8,7%) y de clínica hemisférica parcial (23,5% frente a 18,4%), especialmente del hemisferio izquierdo (78,1% frente a 48,4%). Se administró tratamiento de reperfusión en el 29% de los SEM+ y en el 23% de los SEM-. El tiempo desde el inicio de los síntomas hasta el tratamiento fue 42 minutos más largo en el grupo de pacientes SEM- (175 frente a 133 minutos). CONCLUSIONES: La sensibilidad del SEM para detectar pacientes con ictus en nuestra serie es del 77%. Hemos identificado características clínicas asociadas a la falta de sensibilidad, como los síntomas de territorio vertebrobasilar o el trastorno de lenguaje aislado
AIMS: To determine the sensitivity of stroke detection by emergency medical services (EMS) and to analyse the clinical characteristics of unidentified patients with suspected stroke. PATIENTS AND METHODS: Prospective register of patients with suspected stroke in our area (850,000 inhabitants) from 2011 to 2017. The population that notified the EMS was selected. Of this population, patients with and without stroke code activation by the EMS were compared (EMS+ versus EMS-). Demographics, time to progression, clinical characteristics of the episode and reperfusion therapy administered were recorded. RESULTS: Of a total of 5,497 patients with suspected stroke, 2,087 alerted the EMS: 1,611 (77%) EMS+ and 476 (33%) EMS-. The EMS- patients presented lower scores on the National Institute of Health Stroke Scale (8 vs. 11) and a greater frequency of clinical features of the vertebrobasilar territory (14.1% vs. 8.7%) and partial hemispheric clinical features (23.5% vs. 18.4%), especially in the left hemisphere (78.1% vs. 48.4%). Reperfusion treatment was administered in 29% of EMS+ and 23% of EMS-. The time from symptom onset to treatment was 42 minutes longer in the EMS group (175 versus 133 minutes). CONCLUSIONS: The sensitivity of EMS to detect stroke patients in our series is 77%. We have identified clinical features associated with lack of sensitivity, such as vertebrobasilar territory symptoms or isolated language disorder
