Síndrome de burnout en médicos y personal paramédico / Burnout syndrome in medical practitioners and paramedic personel

Introduction Burnout syndrome is one of the most studied manifestations of job stress. The burnout concept was used by the first time in the area of psychology by Freudenberger in 1974. This psychologist defined it as a condition of fatigue or frustration that is produced by the commitment to a reason, lifestyle or relationship that does not produce the expected effort. Afterwards, Maslach and Jackson proposed three interrelated dimensions: emotional weariness (EW) which estimates the experience of emotional fatigue for the demands of work; the depersonalization (DP) which measures the answers of impersonal type and negative attitudes towards the patients; and the personal accomplishment (PA) which reflects the personal satisfaction and the competition in the practice of the daily work. These dimensions are joined in the Maslach Burnout Inventory (MBI) that is used to measure the afore mentioned syndrome. Several studies have demonstrated the presence of burnout syndrome among medical and paramedic personnel. The close contact with the patients and the work overload are the main reasons of this syndrome. In a multicentre study carried out among 248 doctors of the United States, 40% presented the syndrome with emotional detriment, which coincides with another study carried out with nurses attending patients with palliative care and marrow transplants. Also, in a study carried out among residents of internal medicine of the University of Washington, there was a prevalence of 76% of professional wear, with an autoperception of a lower quality in the professional care of the patients, after comparing them with non-affected residents. In Mexico, a study that investigated burnout level in a group of 450 medical practitioners, nurses and paramedics of 12 institutions revealed the following information: 10.9% presented emotional weariness, 19.6%, depersonalization, and 74.9, low personal accomplishment. Palmer et al. determined a general prevalence of 44% of the syndrome in anesthesiologists. The work overload and the conflict of values were variables that influenced the presence of this syndrome. At the Instituto Mexicano del Seguro Social, Aranda et al., carried out a study among family physicians, where the prevalence of burnout syndrome was 42.3%. Likewise, Cabrera et al., found that, out of 236 studied nurses, 92 (39%) had information compatible with burnout syndrome, with statistically significant differences for the age and the antiquity in the place after comparing them with nurses without burnout syndrome. The burnout syndrome was considered by the World Health Organization as work risk. Its trascendence is rooted in the impact it has in the labor relation between medical and/or paramedic personnel and the health institutions. For this reason, we considered it important to investigate the presence of this syndrome among the medical and paramedic personnel working at hospital of the Mexican social security. Material and Methods Design: Transversal comparative survey. Population: Of a total population of 240 workers of the health area assigned to a general hospital a sample of 160 was obtained that included doctors, nurses and medical assistants based on an average prevalence of the syndrome in 30%, with an alpha level of 0.05 and a power of 90%. Instrument of evaluation: The survey was based on the following sociodemographic and labor variables: age, marital status, academic level, labor antiquity, antiquity of adscript ion to the hospital, category, service and labor shift. To evaluate the burnout syndrome, the MBI questionnaire was used in its previously validated Spanish version. The afore mentioned instrument is an objective way of measuring and determining the burnout level that a person experiences, in its three subscales: EW, DP and PA. The survey consists of 22 items with a Likert type punctuation scale (0-6), of which 9 valued EW, 5, DP, and 8, PA. With regard to the EW, which values the sensation of being emotionally exhausted by the daily contact with people to whom it is necessary to attend as object of work, a punctuation of 27 or higher indicated a high level; between 19 and 26, moderated; and lower than 19, low. In the subscale DP, which measures the degree in which the response towards the patients is cold, distant and impersonal, punctuations above 10 indicated a high level; from 6 to 9, moderated; lower than 6, low. In the subscale PA, which values the feelings of competition and efficiency for the accomplishment of the work and the relation with the people who are being attended, values above 40 indicated personal high accomplishment; from 34 to 39, intermediate; and under 33, low. In the case of obtaining a low emotional depletion, a low depersonalization and a high personal accomplishment, it was considered that no burnout was present. In the rest of the cases, the presence of burnout syndrome was established. Compilation of the information: From August to December, 2005, the survey was applied to each of the workers, indicating them that they should answer and return it in a term not longer than five days. They were all informed previously about the general objectives of the study and its confidential and anonymous character. The head investigator integrated later on the database. Statistical tests: Descriptive and inferential statistics were carried out. The odds ratio and confidence intervals of 95% were calculated to measure the association between the sociodemographic and labor factors with the professional wear. Results Of 160 workers to whom the survey MBI was applied, only 146 returned it in a complete form. Regarding the frequency and the percentages of the three categories studied with the qualifications of low, average and high for every subscale that composes the burnout syndrome, it was observed that the highest evaluations fit the medical assistants. There was a 19.6% prevalence of burnout syndrome among the groups of doctors with at least one of three disturb subscales. Likewise, it was observed that all medical assistants had an alteration of a minimum of two subscales. The nursing personnel did not present information that constitutes a risk for the development of burnout syndrome. Only four sociodemographic and labor variables were found as risk factors for the presence of burnout syndrome, as well as their relation with each of the subscales composing it. When the variables compared age, labor antiquity and time of adscript ion in the service with each of the subscales of the burnout, we observed that depersonalization appeared in older workers and longer antiquity in the position and the lack of personal accomplishment in workers with longer time in the service. There were no statistically significant differences in the subscale of emotional weariness. Discussion In the last years, burnout syndrome has acquired special relevance, mainly because of the series of repercussions that it has in the labor and personal area. Numerous studies exist on the prevalence of this syndrome in different health professionals, but in present work incorporated medical assistants, since they are those who have the first contact with the patients in our institution.

Introducción El concepto de burnout fue utilizado por primera vez en el ámbito de la psicología por Freudenberger en el año de 1974. Este psicólogo lo definió como un estado de fatiga o frustración que se produce por la dedicación a una causa, forma de vida o relación que no produce el esperado esfuerzo. Más tarde, Maslach y Jackson propusieron tres dimensiones interrelacionadas: el cansancio emocional (CE), la despersonalización (DP) y la realización personal (RP). Estas dimensiones se integran en el cuestionario Maslach Burnout Inventory (MBI) que se utiliza para medir dicho síndrome. Material y métodos Diseño: Encuesta transversal comparativa. Población: Se entregó el cuestionario MBI a 160 trabajadores del área de la salud adscritos al Hospital General de Zona con Medicina Familiar 36 de la Ciudad de Cardel, Veracruz. Instrumento de evaluación: Se construyó una encuesta sobre las siguientes variables sociodemográficas y laborales: edad, estado civil, nivel académico, antigüedad laboral, antigüedad de adscripción al hospital, categoría, servicio y turno laboral. Para evaluar el síndrome de burnout se utilizó el cuestionario MBI en su versión en español. Dicho instrumento consta de 22 ítems con escala de puntuación tipo Likert (0-6), de los cuales 9 valoran CE, 5 la DP y 8 la RP. Recolección de la información: Durante el periodo comprendido de agosto a diciembre del 2006 se entregó el cuestionario a cada uno de los trabajadores de la salud. Pruebas estadísticas: Se realizó estadística descriptiva e inferencial. Se calculó la razón de momios e intervalos de confianza de 95% para medir la asociación entre los factores sociodemográficos y laborales con el desgaste profesional. Resultados De 160 trabajadores a quienes se les entregó el cuestionario MBI, sólo 146 lo regresaron en forma completa. En lo que respecta a la frecuencia y los porcentajes de las tres categorías estudiadas se observó que las evaluaciones más altas corresponden a las asistentes médicas. Hubo una prevalencia del síndrome de burnout entre el grupo de médicos del 19.6% con al menos una de las tres subescalas alteradas. Asimismo se observa que en todas las asistentes médicas hubo alteración de un mínimo de dos subescalas. Sólo se encontraron cuatro variables sociodemográficas y laborales como factores de riesgo para la presencia del síndrome de burnout, así como su relación con cada una de la subescalas que lo componen. Discusión Existen numerosos estudios sobre la prevalencia de este síndrome en diferentes profesionales de la salud, pero en el presente trabajo se incorpora a las asistentes médicas, ya que son quienes tienen un primer contacto con los pacientes en nuestra institución. Las cifras de prevalencia del síndrome de burnout reportadas por otros estudios realizados en México entre el personal médico van desde el 42.3% y 44% hasta 50%; en esta investigación la prevalencia fue menor y la dimensión de cansancio emocional es la más afectada. Entre las variables que se consideraron factores de riesgo en nuestro estudio se encuentra el estado civil. Asimismo, el trabajar en el turno vespertino y ofrecer sus servicio en la consulta externa también estuvieron relacionados con mayor predisposición al síndrome de burnout. Al igual que otros estudios, en esta investigación se encontró un mayor nivel de Burnout en profesionales con mayor edad. En lo que respecta a la DP y RP, éstas se presentaron en trabajadores cuya antigüedad laboral era mayor. En conclusión, la prevalencia del síndrome de burnout entre las asistentes médicas es muy alta y es necesario adoptar medidas para evitar el desarrollo de esta patología.

Identificación de un caso de fenilcetonuria a través del tamizaje neonatal / Diagnosis of phenylketonuria by newborn screening

Introducción. La fenilcetonuria es una enfermedad hereditaria autosómica recesiva, causada por un defecto de la enzima fenilalanina hidroxilasa, la cual es responsable de la conversión de la fenilalanina en tirosina. Es la segunda causa más frecuente de retardo mental prevenible. Se desconoce su incidencia en México. En el caso que aquí se presenta, el diagnóstico precoz fue realizado con el tamiz neonatal ampliado y el tratamiento consistió en una dieta baja en fenilalanina. Caso clínico. Paciente masculino de 2 meses de edad sin datos de retardo psicomotor. Se le realizó la prueba de tamiz neonatal a los 3 días de nacido con valores de fenilalanina de 15.25 mg/dL y control a los 2 meses de 39.7 mg/dL. El diagnóstico fue confirmado con el análisis cuantitativo de la concentración de fenilalanina y de tirosina, por medio de la cromatografía de líquidos de alta resolución. Se recomendó un tratamiento de fórmula láctea libre de fenilalanina y dieta vegetariana. Conclusión. Las pruebas de tamizaje neonatal permiten la detección oportuna de enfermedades metabólicas en pacientes asintomáticos, como en el caso de la fenilcetonuria.

Introduction. Phenylketonuria is an autosomic recessive hereditary disease caused by a defect of the enzyme phenylalanine hydroxylase, which is responsible for the phenylalanine conversion to tyrosine. It is the second most frequent although preventable cause of mental retardation. Its incidence in Mexico is unknown. Early diagnosis is made through extended newborn screening, and treatment consists of a low-phenylalanine diet. Case report. Masculine 2-months old with no data of psycho-motor retardation. Newborn screening tests were performed. Values of phenylalanine were 15.25 mg/dL 3 days after delivery, whereas follow-up values at 2 months of age were 39.7 mg/dL. Diagnosis was confirmed with quantitative analysis of phenyla-lanine and tyrosine concentration by HPLC. Treatment consisted of phenylalanine-free infant formula and vegetarian diet. Conclusion. Newborn screening tests allow early detection of metabolic diseases in asymptomatic patients, such as phenylketonuria.
