ABSTRACT

Objectives: The main objective is to determine if there is a correlation between the time elapsed for the diagnosis of fibromyalgia (FM) and the severity of pain in patients who enter the Non-Oncological Chronic Pain Unit (UDCNO) of the San Borja Arriarán Clinical Hospital. The secondary objectives are to characterize the population that enters with FM diagnosis, and to describe the severity of pain according to intensity and related disability.
Materials and methods: correlational study of patients admitted to the UDCNO with a diagnosis of FM, who were evaluated at the time of admission pain through the Numerical Pain Scale (NDT) and the Chronic Pain Grade Questionnaire (CPGC). Data were obtained for the characterization of the population through the clinical record: schooling, employment status, tobacco consumption, pharmacological and non-pharmacological treatments indicated at the time of admission to the UDCNO. In addition, data on episodes of falls in the last year were obtained.
Results: Of the 38 patients evaluated, 100 % were women, with an average age of 56 years. The average time for diagnosis was 36 months (± 32.2 months), with an evolution time at admission to UDCNO of 53.8 months on average (± 36.4 months). The intensity of the pain measured by NTD was on average 7.29 (± 2.02). There was no association between diagnostic opportunity and pain intensity at the time of admission. 94 % were in grades 3 and 4 of the CPGC, corresponding to high pain intensity and moderate to severe limitation.
Conclusions: According to our study, the correlation between the time elapsed at diagnosis and the intensity of pain measured at admission is low and not statistically significant, which we consider is given by the multiple aspects that interfere in the experience of pain, which do not depend only of the evolution time. In this sense, a very high percentage of the population evaluated with high intensity of pain and moderate to severe limitation stands out.



RESUMEN

Objetivos: El objetivo principal es determinar si existe correlación entre el tiempo transcurrido para el diagnóstico de fibromialgia (FM) con la severidad del dolor que presentan los pacientes que ingresan a la Unidad de Dolor Crónico no Oncológico (UDCNO) del Hospital Clínico San Borja Arriarán. Los objetivos secundarios son caracterizar a la población que ingresa con diagnóstico FM y describir la severidad del dolor según intensidad y la discapacidad relacionada.
Materiales y métodos: Estudio correlacional de pacientes que ingresan a la UDCNO con diagnóstico de FM, a los que se les evaluó al momento del ingreso dolor a través de la Escala Numérica del Dolor (END) y del Cuestionario de graduación del dolor Crónico (CGDC). Se obtuvieron datos para la caracterización de la población a través de la ficha clínica: escolaridad, situación laboral, consumo de tabaco, tratamientos farmacológicos y no farmacológicos indicados al momento del ingreso a la UDCNO. Además se obtuvieron datos de episodios de caídas en el último año.
Resultados: De los 38 pacientes evaluados, el 100 % fueron mujeres, con una edad promedio de 56 años. El tiempo promedio para el diagnóstico fue de 36 meses (± 32,2 meses), con un tiempo de evolución al ingreso a UDCNO de 53,8 meses en promedio (± 36,4 meses). La intensidad del dolor medida por END fue en promedio 7,29 (± 2,02). No hubo asociación entre oportunidad diagnóstica e intensidad del dolor al momento del ingreso. El 94 % se encontraba en los grados 3 y 4 del CGDC, correspondientes a alta intensidad del dolor y limitación moderada a severa.
Conclusiones: Según nuestro estudio la correlación entre el tiempo transcurrido al diagnóstico y la intensidad del dolor medida al momento del ingreso es baja y no estadísticamente significativa, que consideramos está dada por los múltiples aspectos que interfieren en la vivencia del dolor, que no dependen solo del tiempo de evolución. En ese sentido destaca un muy alto porcentaje de la población evaluada con alta intensidad de dolor y limitación moderada a severa.
