Factores asociados a recibir la vacunación antigripal en profesionales de atención primaria / Factors associated with influenza immunization in primary care health workers

Objetivo: Conocer la cobertura vacunal antigripal en profesionales de atención primaria y determinar los factores asociados a la vacunación (temporada 2013-2014). Métodos: Estudio transversal realizado a 287 profesionales que cumplimentaron un cuestionario que incluía preguntas sobre conocimientos, creencias y actitudes frente la gripe y la vacunación. Se determinó la cobertura y aquellas variables asociadas a recibir la vacunación, utilizando modelos de regresión logística no condicional. Resultados: La participación fue del 47,2%. La cobertura vacunal fue del 60,3%; fue mayor en los profesionales > 55 años de edad, mujeres y pediatras. Factores asociados a recibirla fueron la percepción de que la vacunación protege la propia salud (odds ratio ajustada [ORa]: 11,1; intervalo de confianza del 95% [IC95%]: 3,41-35,9) y de que es efectiva (ORa: 7,5; IC95%: 0,9-59,3). No se halló asociación entre la vacunación y el conocimiento sobre la gripe y la vacunación, pero sí para prescribirla en gestantes, en > 65 años y en inmunodeprimidos. Conclusiones: Se recomienda diseñar estrategias para aumentar la cobertura, basadas en cambiar actitudes negativas frente a la vacunación (AU)

Objective: To identify the influenza vaccination coverage in healthcare workers in primary care and to determine the factors associated with vaccination (2013-2014 season). Methods: A cross-sectional study was carried out among 287 healthcare workers who completed a questionnaire that included questions about knowledge, beliefs and attitudes to influenza and vaccination. We estimated the vaccine coverage and identified the variables associated with vaccination of healthcare workers by using non-conditional logistic regression models. Results: The participation rate was 47.2%. Vaccination coverage was 60.3% and was higher in workers older than 55 years, women and pediatricians. The factors associated with healthcare worker vaccination were the perception that vaccination confers protection (aOR: 11.1; 95%CI: 3.41-35.9) and the perception that it is effective (aOR: 7.5; 95%CI: 0.9-59.3). No association was found between receiving the vaccine and knowledge of influenza or vaccination. However, an association was found with prescribing vaccination to pregnant women, to persons older than 65 years, and to immunosuppressed individuals. Conclusions: Strategies should be designed to increase coverage, based on changing negative attitudes of healthcare workers to vaccination (AU)

Factores asociados a la mortalidad global en los pacientes diagnosticados de enfermedad pulmonar obstructiva crónica / Risk factors for mortality in patients with chronic obstructive pulmonary disease

OBJETIVO: Identificar los factores predictores de mortalidad en los pacientes con enfermedad pulmonar obstructiva crónica (EPOC). DISEÑO: Estudio de cohortes retrospectivas. Emplazamiento: Atención Primaria de Lleida, España. PARTICIPANTES: Se incluyó a los 2.501 pacientes mayores de 40 años diagnosticados de EPOC seguidos en Atención Primaria y con al menos una espirometría compatible con EPOC en los 24 meses previos al inicio del estudio (2010). MEDICIONES PRINCIPALES: La variable dependiente fue la mortalidad global en el periodo 01/11/2010-31/10/2013 (por todas las causas) y las independientes: parámetros espirométricos, gravedad (GOLD) y variables clínicas. Se analizó su asociación con la mortalidad mediante el cálculo de las odds ratio ajustadas mediante un modelo de regresión logística no condicional. RESULTADOS: La edad media ± desviación estándar de los 2.501 pacientes al inicio del estudio fue de 68,4 ± 11,6 años. El 75,0% eran varones. El 50,8% presentaba un nivel de gravedad leve, seguido por el moderado (35,3%), grave (9,4%) y muy grave (4,4%). La mortalidad a los 3 años fue del 12,55%. Los factores asociados a la mortalidad en la EPOC fueron: edad, género masculino, exacerbaciones previas, comorbilidad asociada, tabaquismo, gravedad (GOLD) y no haber recibido la vacunación antigripal estacional, con un área bajo la curva ROC de 0,76. CONCLUSIONES: La aplicación de estas variables, fáciles y factibles de recoger en la práctica clínica, permitiría identificar a aquellos pacientes con mayor riesgo de mortalidad y que podrían beneficiarse de estrategias preventivas/terapéuticas para conseguir aumentar la supervivencia

OBJECTIVE: To identify risk factors of mortality in patients with chronic obstructive pulmonary disease (COPD). DESIGN: A retrospective cohort study. LOCATION: Primary care setting in Lleida, Spain. PARTICIPANTS: 2.501 patients older than 40 years with at least a spirometry in the 24 months prior to the beginning of the study were followed for 3 years. MAIN MEASUREMENTS: The dependent variable was the overall mortality in the period 11/01/2010-10/31/2013; and the independents: spirometric parameters, severity (GOLD) and clinical variables. Their association with mortality was analyzed by calculating the adjusted odds ratio using a non-conditional logistic regression model. RESULTS: The average age of 2.501 patients at the beginning of the study was 68.4 years (SD = 11.6).75.0% were males.50.8% had a mild severity COPD, followed by moderate (35.3%), severe (9.4%) and very severe (4.4%). Mortality rate for the all period was 12.55%. The variables of the predictive model were: age, male sex, previous exacerbations, number of visits to primary care, comorbidity, smoking, severity of COPD (GOLD) and not receiving influenza vaccination, with an area under the ROC curve of 0.76. CONCLUSIONS: This model, easy and quick to apply, would identify those patients at increased risk of mortality and who could benefit from preventive strategies to improve their survival

Corneal biomechanical properties in floppy eyelid syndrome.

PURPOSE: To determine corneal biomechanical properties in patients with floppy eyelid syndrome (FES) and to compare them with eyes of controls. METHODS: This case-control study included 208 eyes (72 eyes with FES and 136 without FES) of 107 patients (37 patients with FES and 70 without FES). Patients underwent a complete clinical eye examination that included corneal biomechanical evaluation carried out with the Reichert Ocular Response Analyzer. RESULTS: Corneal hysteresis (CH), corneal resistance factor (CRF), central corneal thickness (CCT), Goldmann-correlated intraocular pressure (IOPg), and corneal-compensated intraocular pressure (IOPcc) were evaluated. Mean CH was significantly lower in patients with FES than in those without FES (9.51 ± 1.56 vs. 11.66 ± 9.11; P < 0.001). These results remained statistically significant after adjusting for age and apnea-hypoapnea index (AHI) (P = 0.028). Mean CRF was 10.02 ± 2.08 in the group of patients with FES and 11.21 ± 5.36 in the group of patients without FES (P = 0.001). Mean IOPcc was 17.7 ± 4.8 in patients with FES and 16.3 ± 4.4 in those without FES (P = 0.036). After adjusting for age and AHI, these differences in CRF and IOPcc were not statistically significant (P = 0.26 and P = 0.87, respectively). No statistically significant difference was found between patients with and without FES for Goldmann-correlated intraocular pressure or CCT. CONCLUSIONS: Patients with FES had statistically lower CH values. Our findings suggest that corneal biomechanical properties could be changed in patients with FES, reflecting additional structural changes in FES.

Obstructive sleep apnea/hypopnea and systemic hypertension.

Obstructive sleep apnea/hypopnea (OSAH) syndrome is a highly prevalent condition. Severe OSAH affects 2-6% of the population, although only 10% of subjects are correctly diagnosed and treated. OSAH is an important and unresolved public health care problem because of its role in the development of cardiovascular events, negative impact on quality of life, and as a cause of traffic accidents. Longitudinal and cross-sectional studies have shown a strong association between OSAH and hypertension. Moreover, a number of open-label studies, the majority of 21 controlled studies included in the present review, a systematic review, and 4 recent meta-analyses have shown a reduction of blood pressure (BP) of about 2 mm Hg with continuous positive airway pressure (CPAP). This lowering of blood pressure is significant in terms of reduction of both cardiovascular and cerebrovascular risk and death. The effect is greater in hypertensive subjects and in those with more severe OSAH. Accordingly, treatment with CPAP could be considered in patients with severe OSAH and hypertension even in the absence of symptoms. The challenge to researchers is to find markers for discriminating subjects in whom blood pressure will decrease from non-responders. This will help to refine relevant clinical indicators for CPAP treatment in clinical practice.

[Resources and delays in the diagnosis of sleep apnea-hypopnea syndrome]. / Recursos y demoras en el diagnóstico del síndrome de apneas-hipopneas durante el sueño (SAHS).

OBJECTIVE: The demand for consultations and diagnostic studies for sleep apnea-hypopnea syndrome (SAHS) has increased, and this has led to considerable delays. We therefore need an updated evaluation of the diagnostic situation to serve as a management tool for specialists and health care administrations responsible for solving the problem. The objective of the present study was to carry out a descriptive analysis of the situation regarding the diagnosis of SAHS in Spanish hospitals. METHODS: We undertook a descriptive cross-sectional observational study. Public and private hospitals listed in the Ministry of Health's 2005 catalog of health care institutions were contacted, and those that routinely evaluate patients for SAHS were included in the study. The person in charge of each hospital filled in a questionnaire concerning the availability of resources and waiting periods for diagnosis. RESULTS: Of the 741 hospitals we contacted, 217 routinely evaluated patients for SAHS. In 88% of these, respiratory polygraphy (RP) (n=168) or polysomnography (PSG) (n=97) was available. The mean waiting period was 61 days for consultation and 224 days for RP. The mean number of RP systems was 0.99 per 100,000 inhabitants, while the recommended number is 3 per 100,000 inhabitants. The mean waiting period for PSG was 166 days. The mean number of PSG beds was 0.49 per 100,000 inhabitants, while the recommended number is 1 per 100,000. CONCLUSIONS: We observed a marked inadequacy of resources that has led to unacceptable waiting periods. While there has been a favorable change in the situation regarding SAHS diagnosis compared to previous studies, there is still room for improvement and it is urgent that healt hcare authorities allocate more resources to this public health problem.

Recursos y demoras en el diagnóstico del síndrome de apneas-hipopneas durante el sueño (SAHS) / Resources and delays in the diagnosis of sleep apnea-hypopnea syndrome

Objetivo: La demanda de consultas y estudios diagnósticos del síndrome de apneas-hipopneas durante el sueño (SAHS) se ha incrementado, lo que ha llevado a importantes demoras. Por tanto, es precisa una evaluación actualizada de la situación del diagnóstico que sirva como herramienta de gestión a especialistas y las administraciones sanitarias que tienen la responsabilidad de solventar el problema. El objetivo del presente estudio ha sido realizar un análisis descriptivo de la situación del diagnóstico del SAHS en los hospitales españoles. Métodos: Se ha realizado un estudio descriptivo, observacional y transversal. Se estableció contacto con los centros públicos y privados incluidos en el catálogo de instituciones sanitarias del Ministerio de Sanidad de 2005. Se incluyeron aquellos que evaluaban habitualmente a pacientes con SAHS. El responsable de cada centro rellenó un cuestionario sobre disponibilidad de recursos y demoras para el diagnóstico. Resultados: De los 741 centros con los que se estableció contacto, 217 evaluaban habitualmente a pacientes con SAHS. El 88% disponía de poligrafía respiratoria (PR) (n = 168) o polisomnografía (PSG) (n = 97). La demora media en consulta fue de 61 días, y la demora media para realizar PR, de 224 días. La media de equipos de PR fue de 0,99/100.000 habitantes, cuando lo recomendable es 3/100.000. La demora media para PSG fue de 166 días. La media de camas de PSG fue de 0,49/100.000 habitantes y lo recomendable es 1/100.000. Conclusiones: Se observa una notable deficiencia de recursos que lleva a inaceptables listas de espera. Aunque la situación del diagnóstico de SAHS ha cambiado favorablemente con respecto a estudios previos, sigue siendo mejorable y es imprescindible que las autoridades sanitarias dediquen más recursos a este problema de salud pública
