Mortalidad a 30 días en pacientes con fractura de fémur proximal durante la pandemia COVID-19 en Vizcaya (País Vasco) / Thirty-day mortality in patients with a proximal femur fracture during the COVID-19 pandemic in Biscay (Basque Country)

Objetivos: Comparar la tasa de mortalidad a 30 días en pacientes con fractura de fémur proximal (FFP) y coinfección por SARS-CoV-2 vs. FFP sin coinfección. Diseño: Estudio retrospectivo comparativo. Escenario: Tres hospitales universitarios en Vizcaya (País Vasco, España). Pacientes: Setenta y siete pacientes mayores de 65 años con FFP (AO 31-A y 31-B). Intervención: Entre el 9 de marzo y el 15 de abril de 2020. El grupo COVID-19 incluía pacientes con infección confirmada mediante el test PCR-RT. Medidas de resultados principales: Tasa de mortalidad a 30 días y factores de riesgo de mortalidad. Resultados: Diez de los 77 pacientes presentaron coinfección por SARS-CoV-2. La edad media fue de 85 años. Los pacientes infectados presentaban un IMC mayor (29,53 kg/m2) frente a los no infectados (24,09 kg/m2) (p = 0,001). No hubo diferencias significativas en el índice de comorbilidad de Charlson, la puntuación ASA, el uso de anticoagulantes o el deterioro cognitivo. Siete pacientes del grupo COVID-19 (7/10) desarrollaron neumonía (vírica), frente a un solo caso(1/67) de neumonía (bacteriana) en el grupo control (p < 0,001). La mortalidad a 30 días fue mayor (p = 0,03) en los pacientes con COVID-19 (40%) que en el grupo control (11,9%). La edad ≥ 91 años, la clase IV ASA y el IMC > 25 kg/m2 fueron predictores significativos de mortalidad a 30 días. Todas las muertes en el grupo COVID-19 ocurrieron intrahospitalariamente. Conclusiones: La infección por SARS-CoV-2 en pacientes con PFF resultó en tasas más altas de mortalidad temprana, siendo la neumonía por COVID-19 la principal causa directa de mortalidad. Nivel de evidencia: Estudio nivel III.(AU)

Objectives: Compare 30-day mortality rate following a proximal femur fracture (PFF) and SARS-CoV-2 infection versus a PFF and no SARS-CoV-2 infection. Design: Retrospective comparative study. Setting: Three university hospitals in Biscay province (Basque Country, Spain). Patients: 77 patients over 65 years-old with PFF (AO 31-A and 31-B). Intervention: Study conducted between 9 March and 15 April 2020. The COVID-19 group included only patients with SARS-CoV-2 infection, confirmed by a positive RT-PCR test. Main outcome measurements: 30-Day mortality rate and risk factors for mortality. Results: Of a total 77 patients, 10 were diagnosed with SARS-CoV-2 infection. Mean age was 85 years. Patients with SARS-CoV-2 infection had higher BMI (29.53 kg/m2) compared to patients without infection (24.09 kg/m2) (p = 0.001). No significant differences were found between both groups in terms of the Charlson Comorbidity Index, ASA score, use of oral anticoagulants or presence of cognitive impairment. Seven of the 10 patients in the COVID-19 group developed (viral) pneumonia, as compared to one single case (1/67) of (bacterial) pneumonia in the control group (p < 0.001). Thirty-days mortality was higher (p = 0.03) in COVID-19 patients (40%) than in those in the control group (11.9%). In the multivariate analysis, age ≥ 91 years-old, ASA class IV and BMI > 25 kg/m2 were significant predictors of 30-day mortality. All deaths in the COVID-19 group occurred while the patients were hospitalized. Conclusions: SARS-CoV-2 infection in patients with a PFF was seen to result in higher rates of early mortality, with COVID-19-related pneumonia being the leading direct cause of mortality. Level of evidence: Level III study.(AU)

Factores de riesgo de deterioro clínico en pacientes ingresados por COVID-19: estudio caso-control / Risk factors for clinical deterioration in patients admitted for COVID-19: A case-control study

Introducción: Existe controversia sobre los mejores factores predictores de deterioro clínico en la COVID-19. Objetivo: Identificar factores predictores de riesgo de deterioro en pacientes hospitalizados por COVID-19. Métodos Diseño: caso-control anidado dentro de una cohorte. Ámbito: 13 centros de agudos de Osakidetza-Servicio Vasco de Salud. Participantes: se consideró casos a pacientes hospitalizados por COVID-19 con deterioro clínico, definido como la aparición de síndrome de distrés respiratorio del adulto grave, ingreso en UCI o fallecimiento. Se emparejaron 2controles por caso en función de la edad. Se recogieron variables sociodemográficas, comorbilidades, tratamientos basales, síntomas y fecha de inicio, consultas previas, así como variables clínicas, analíticas y radiológicas. Se creó un modelo explicativo del deterioro clínico mediante regresión logística condicional. Resultados: Se incluyeron 99 casos y 198 controles. Mediante análisis de regresión logística las variables independientes asociadas con deterioro clínico fueron: saturación de O2 en Urgencias ≤ 90% (OR=16,6, IC del 95%, 4-68), radiografía de tórax patológica (OR=5,6, IC del 95%, 1,7-18,4), PCR> 100mg/dL (OR=3,62, IC del 95% 1,62-8) y trombocitopenia <150.000 plaquetas (OR=4, IC del 95%, 1,84-8,6) y, entre los antecedentes, haber padecido infarto agudo de miocardio (OR=15,7, IC del 95%, 3,29-75,09), EPOC (OR=3,05, IC del 95%, 1,43-6,5) o hipertensión arterial (OR=2,21, IC del 95%1,11-4,4). El área bajo la curva alcanzado por el modelo fue 0,86. En el análisis univariado, se asociaron con mejor evolución clínica el sexo femenino, la presencia de tos seca y dolor de garganta, pero no resultaron significativas en el análisis multivariado. Conclusiós:Las variables identificadas podrían ser de utilidad en la práctica clínica para la detección de pacientes con alto riesgo de mala evolución (AU)

Introduction: There is controversy regarding the best predictors of clinical deterioration in COVID-19. Objective: This work aims to identify predictors of risk factors for deterioration in patients hospitalized due to COVID-19. Methods Design: Nested case-control study within a cohort. Setting: 13 acute care centers of the Osakidetza-Basque Health Service. Participants: Patients hospitalized for COVID-19 with clinical deterioration—defined as onset of severe ARDS, ICU admission, or death—were considered cases. Two controls were matched to each case based on age. Sociodemographic data; comorbidities; baseline treatment; symptoms; date of onset; previous consultations; and clinical, analytical, and radiological variables were collected. An explanatory model of clinical deterioration was created by means of conditional logistic regression. Results: A total of 99 cases and 198 controls were included. According to the logistic regression analysis, the independent variables associated with clinical deterioration were: emergency department O2 saturation ≤90% (OR 16.6; 95%CI 4-68), pathological chest X-ray (OR 5.6; 95%CI 1.7-18.4), CRP>100mg/dL (OR 3.62; 95%CI 1.62-8), thrombocytopenia with <150,000 platelets (OR 4; 95%CI 1.84-8.6); and a medical history of acute myocardial infarction (OR 15.7; 95%CI, 3.29-75.09), COPD (OR 3.05; 95%CI 1.43-6.5), or HT (OR 2.21; 95%CI 1.11-4.4). The model's AUC was 0.86. On the univariate analysis, female sex and presence of dry cough and sore throat were associated with better clinical progress, but were not found to be significant on the multivariate analysis. Conclusion: The variables identified could be useful in clinical practice for the detection of patients at high risk of poor outcomes (AU)

Factores pronósticos tras una luxación traumática de cadera. Estudio retrospectivo a largo plazo / Prognostic factors after a traumatic hip dislocation. A long-term retrospective study

Introducción. Las luxaciones o fracturas-luxaciones de la cadera pueden suponer severas complicaciones como la artrosis o la necrosis. El objetivo de este estudio fue identificar las variables y los factores pronósticos asociados con resultados clínicos y radiológicos a largo plazo tras una luxación traumática de cadera. Material y métodos. Se realizó un estudio retrospectivo de todas las luxaciones y fracturas-luxaciones tratadas desde enero de 1999 a diciembre de 2012. Una tomografía axial computerizada fue realizada tras la reducción en todos los casos. Para la evaluación de los resultados clínicos se utilizó el Harris Hip Score y la escala Merlé-d'Aubigné-Postel, mientras que los resultados radiológicos se evaluaron con la clasificación de Thompson-Epstein. Resultados. Se identificaron 30 casos en 29 pacientes, con un seguimiento medio de 11 años (rango 4-17). Existió una mayor frecuencia de luxaciones simples (21; 70%) respecto a luxaciones complejas (9; 30%). Se realizó una reducción cerrada en menos de 6h en todos los casos excepto en uno (29; 96,7%). Todos los pacientes con luxaciones simples tuvieron excelente resultado sin signos radiológicos de artrosis al final del seguimiento (p<0,01). Del total de la muestra, 4 pacientes desarrollaron signos artrósicos (13,3%) y 3 pacientes presentaron necrosis avascular (10%). Cinco pacientes con fragmentos intraarticulares fueron tratados de forma conservadora, y 3 de ellos desarrollaron artrosis (p<0,05). Conclusión. Nuestro estudio muestra que las luxaciones complejas tienen peores resultados funcionales y radiológicos que las luxaciones simples. Hemos encontrado una fuerte asociación entre cuerpos libres intraarticulares y artrosis, por lo que la extracción de esos fragmentos podría ser considerada (AU)

Introduction. Traumatic hip dislocations can have devastating complications such as osteoarthritis or osteonecrosis. The aim of this study was to identify the variables and prognostic factors associated with clinical and radiological outcome after a traumatic hip dislocation at long-term follow-up. Material and methods. A review was performed of all dislocations and fracture-dislocations of the hip from January 1999 to December 2012. A computed tomography scan was performed after reduction in all cases. The Harris Hip Score and modified Merle-d'Aubigné-Postel method were used for clinical evaluation and radiological assessment was performed according to the Thompson and Epstein classification. Results. There were 30 cases in 29 patients with a mean follow-up of 11 years (range, 4-17). The great majority were simple dislocations (21; 70%) vs. complex dislocations (9; 30%). Closed reduction was performed in less than 6h in all except one case (29; 96.7%). All of the patients with simple dislocations had an excellent outcome without radiological signs of osteoarthritis at the end of the follow-up (P<.01). Overall, arthritic signs had developed in 4 patients (13.3%) and avascular necrosis was noted in 3 patients (10%). Five patients with intraarticular fragments were treated non-operatively, and 3 of them developed arthritic changes (P<.05). Conclusion. Our study suggests that complex dislocations are associated with poorer functional and radiological outcomes than simple dislocations. We also found a strong association between intraarticular fragments and osteoarthritis, so surgical fragment removal could be considered in these cases (AU)

Síndrome de cauda equina por hernia discal lumbar: demora quirúrgica y su relación con el pronóstico / Cauda equina syndrome secondary to lumbar disc herniation: Surgical delay and its relationship with prognosis

Objetivo. Constatar si la demora en más de 48 h en el tratamiento quirúrgico de los pacientes con síndrome de cauda equina (SCE) influyó en el resultado clínico de nuestros pacientes. Material y métodos. Estudio retrospectivo de 18 pacientes intervenidos en nuestro centro desde marzo de 2000 a enero de 2012, tras presentar SCE. Se recogió la situación clínica pre- y postoperatoria: existencia de dolor lumbar y/o ciático, alteración sensitiva en periné, déficit motor y sensitivo en extremidades inferiores y el grado de incontinencia esfinteriana (SCE completo o incompleto). Se realizó una valoración mediante el índice de discapacidad de Oswestry. Resultados. Teniendo en cuenta el inicio de los síntomas, el 44% (8 de 18) de los pacientes se intervinieron de forma precoz (menos de 48 h). Ninguno de los pacientes con SCE completo intervenidos precozmente tuvieron incontinencia urinaria residual, presentando además mayor grado de recuperación motora. De los 5 pacientes con SCE completo intervenidos de forma tardía (más de 48 h), 3 continuaron con incontinencia urinaria residual. Al final del seguimiento se obtuvo una media de 12,55 en las escala de discapacidad de Oswestry. Conclusión. Aunque no se han encontrado diferencias estadísticamente significativas, en nuestra serie hemos observado mayor recuperación motora y esfinteriana en los pacientes que fueron intervenidos antes de las 48 h (AU)

Objective. To determine whether surgical treatment delayed for more than 48 hours in patients with cauda equina syndrome (CES) influenced the clinical outcome. Material and methods. A retrospective study of 18 patients treated in our hospital from March 2000 to January 2012, after presenting with CES. The pre- and post-operative clinical status was determined: existence of back pain and/or sciatica, sensory disturbance in the perineum, sensory and motor deficits in the lower extremities, and the degree of sphincter incontinence (complete or incomplete CES). A clinical assessment was performed using the Oswestry disability index. Results. As regards the onset of symptoms, 44% (8 of 18) of patients were treated at an early stage (within 48 hours). None of the patients with complete CES operated in the early stage had urinary incontinence, and also had greater motor recovery. Of the 5 patients with complete CES who underwent delayed surgery, 3 showed residual urinary incontinence. A mean of 12.55 was obtained on the Oswestry disability index scale at the end of follow-up. Conclusion. Although no statistically significant difference was found in our study, we observed greater motor and sphincter recovery in patients who were operated on within 48 hours (AU)

Analgesia basada en infusión continua de anestésico local a nivel interfascial tras cirugía de colon laparoscópico: ensayo clínico / Analgesia with interfascial continuous wound infiltration after laparoscopic colon surgery: a randomized clinical trial

Objetivos. Tanto para cirugía laparoscópica como para cirugía abierta la analgesia multimodal puede ayudar a controlar el dolor postoperatorio. La colocación de un catéter en la herida quirúrgica de manera intraoperatoria tras cirugía de colon podría optimizar el control del dolor con menor consumo de opiáceos y menos efectos secundarios. Método. Realizamos un estudio prospectivo, aleatorizado de pacientes reclutados para cirugía de colon laparoscópica en el Hospital de Galdakao-Usansolo de enero de 2012 a enero de 2013. Los pacientes fueron asignados aleatoriamente al grupo del catéter o al grupo de la analgesia postoperatoria estándar. Un miembro de la Unidad de dolor agudo monitorizó todos los pacientes a lo largo de 48 h tras la cirugía. Las variables principales analizadas fueron la escala numérica verbal y la cantidad de morfina intravenosa utilizada por cada paciente mediante PCA. Resultados. Se incluyeron 92 pacientes en el estudio, 43 en el grupo con catéter y 49 en el estándar. Se observaron diferencias estadísticamente significativas en el consumo de morfina entre ambos grupos a lo largo de todo el periodo. La cantidad total de morfina consumida en el grupo del catéter fue de 5,63 ± 5,02 mg y de 21,86 ± 17,88 mg en el grupo de analgesia estándar (p = 0,0001). Los pacientes con catéter presentaban menores valores en la escala numérica verbal. No se encontraron efectos adversos asociados a la colocación del catéter y la administración de anestésico local. El grupo de catéter presentó menor estancia hospitalaria respecto al otro grupo (p = 0,02). Conclusión. En los pacientes intervenidos de cirugía de colon laparoscópico una infusión continua de anestésico local a través de un catéter interfascial durante 48 h tras la cirugía reduce la percepción del dolor y el consumo de morfina intravenosa, disminuyendo la estancia hospitalaria (AU)

Objectives. For major laparoscopic surgery, as with open surgery, a multimodal analgesia plan can help to control postoperative pain. Placing a wound catheter intraoperatively following colon surgery could optimize the control of acute pain with less consumption of opioids and few adverse effects. Methods. We conducted a prospective, randomized, study of patients scheduled to undergo laparoscopic colon surgery for cancer in Galdakao-Usansolo Hospital from January 2012 to January 2013. Patients were recruited and randomly allocated to wound catheter placement plus standard postoperative analgesia or standard postoperative analgesia alone. A physician from the acute pain management unit monitored all patients for pain at multiple points over the first 48 hours after surgery. The primary outcome variables were verbal numeric pain scale scores and amount of intravenous morphine used via patient controlled infusion. Results. 92 patients were included in the study, 43 had a wound catheter implanted and 49 did not. Statistically significant differences in morphine consumption were observed between groups throughout the course of the treatment period. The mean total morphine consumption at the end of the study was 5.63 ± 5.02 mg among wound catheter patients and 21. 86 ± 17.88 mg among control patients (P = .0001). Wound catheter patients had lower pain scale scores than control patients throughout the observation period. No adverse effects associated with the wound catheter technique were observed. The wound catheter group showed lower hospital stays with statistically significant difference (P = .02). Conclusions. In patients undergoing laparoscopic colon surgery, continuous infusion of local anaesthetics through interfascial wound catheters during the first 48 h aftersurgery reduced the level of perceived pain and also reduced parenteral morphine consumption with no associated adverse effects and lower hospital stays (AU)

Cauda equina syndrome secondary to lumbar disc herniation: Surgical delay and its relationship with prognosis. / Síndrome de cauda equina por hernia discal lumbar: demora quirúrgica y su relación con el pronóstico.

OBJECTIVE: To determine whether surgical treatment delayed for more than 48 hours in patients with cauda equina syndrome (CES) influenced the clinical outcome. MATERIAL AND METHODS: A retrospective study of 18 patients treated in our hospital from March 2000 to January 2012, after presenting with CES. The pre- and post-operative clinical status was determined: existence of back pain and/or sciatica, sensory disturbance in the perineum, sensory and motor deficits in the lower extremities, and the degree of sphincter incontinence (complete or incomplete CES). A clinical assessment was performed using the Oswestry disability index. RESULTS: As regards the onset of symptoms, 44% (8 of 18) of patients were treated at an early stage (within 48 hours). None of the patients with complete CES operated in the early stage had urinary incontinence, and also had greater motor recovery. Of the 5 patients with complete CES who underwent delayed surgery, 3 showed residual urinary incontinence. A mean of 12.55 was obtained on the Oswestry disability index scale at the end of follow-up. CONCLUSION: Although no statistically significant difference was found in our study, we observed greater motor and sphincter recovery in patients who were operated on within 48 hours.

Changes in health-related quality of life and activities of daily living after hip fracture because of a fall in elderly patients: a prospective cohort study.

BACKGROUND: The impact of hip fracture because of a fall on health-related quality of life (HRQoL) and activities of daily living (ADL) have not been well established. AIM: To evaluate changes in HRQoL and the ability to conduct ADL among patients with hip fracture because of a fall and to compare these changes with patients who did not fall and break a hip, adjusting by gender and age. METHODS: Adults aged 65 or more who attended the emergency departments of seven public hospitals were recruited in a prospective double-cohort study (fracture cohort, n = 776; non-fracture cohort, n = 115). ADL and HRQoL were assessed at baseline (during the postfall hospitalisation or by telephone afterwards) and 6 months later using the Barthel Index and the Lawton Brody Index for ADL, and the Short Form Health Survey (SF-12) and Western Ontario and McMaster Universities Osteoarthritis Index short form (WOMAC-SF) for HRQoL. RESULTS: Adjusting by gender, age and baseline status, a hip fracture was a strong predictor of decline in all outcomes measured except for mental quality of life among men (measured by SF-12). Hip fracture patients younger than 74 years reported significantly more pain (measured by WOMAC-SF) than the comparison group (p = 0.02), but this difference was not observed among older patients (p = 0.19 for 75-84 years; p = 0.39 for ≥ 85 years). DISCUSSION: Hip fractures have profound effects on HRQoL and ADL in both men and women, regardless of age. This indicates the need for special follow-up care of elderly hip fracture patients in the immediate and late postfracture periods.

Impact of interdisciplinary treatment on physical and psychosocial parameters in patients with fibromyalgia: results of a randomised trial.

AIM: Fibromyalgia (FM) is a persistent disorder that can have a devastating effect on patients' lives. The purpose of the study was to assess the effects of an interdisciplinary treatment for FM on patients' physical and psychosocial parameters. METHODS: A randomised controlled clinical trial carried out among 153 patients. The control group (CG) received standard pharmacological therapy. The experimental group (EG) received an interdisciplinary treatment. At baseline and 6 months after the intervention, participants completed assessment for impact of FM in the quality of life, anxiety, depression, coping with pain, social support and satisfaction with the treatment. RESULTS: A total of 110 participants completed the trial. Six months after the intervention, statistically significant improvements in quality of life (p = 0.04), pain (p = 0.03), self-assertiveness (p = 0.01), mental self-control (p = 0.05), social support (p = 0.02) and satisfaction (p = 0.0001) were observed in the EG. Randomisation to the EG was identified as a predictor for improvement. CONCLUSION: An interdisciplinary intervention may be appropriate for patients referred to a hospital pain management unit.

Health-related quality of life and functionality in elderly men and women before and after a fall-related wrist fracture.

AIMS: To evaluate health-related quality of life (HRQoL) and functionality among older men and women who suffered a wrist fracture because of a fall and to identify postfracture consequences. METHODS: Observational, prospective cohort study of patients recruited in the emergency departments (ED) of six public hospitals of the Basque Health Service and one of the Catalan Health Service. Two groups of adults aged 65 or older were recruited: 960 with wrist fractures because of falls (fracture cohort) and 119 without fall-related wrist fractures in the previous year (non-fracture cohort). We collected sociodemographical and clinical data; general and specific HRQoL data measured by the 12-Item Short Form Health Survey (SF-12) and a short version of the Disabilities of the Arm, Shoulder, and Hand instrument (QuickDASH); and data about basic (BADL) and instrumental (IADL) activities of daily living, measured by the Barthel Index and the Lawton and Brody Index (LBI). RESULTS: Women with wrist fractures exhibited greater declines than men 6 months after the fall in all questionnaires except the LBI, and greater declines than those in the non-fracture cohort independent of gender. Patients aged 80 years and older presented with worse baseline scores in all the outcome measures and lost more HRQoL and functionality after wrist fractures. DISCUSSION: Women and older individuals experienced the greatest reductions in HRQoL and functionality after a fall-related wrist facture, suggesting that they might merit special attention in clinical care and public health policy. CONCLUSIONS: Specific prevention strategies may be needed to avoid or reduce the consequences of fall-related wrist fractures.

Evaluation of the psychometric characteristics of the Spanish version of the Anorectic Behaviour Observation Scale.

AIMS: The Anorectic Behaviour Observation Scale (ABOS) was designed to obtain information from relatives about behaviours and attitudes of patients with eating disorders (ED). The aim of this study was to validate the ABOS into Spanish. METHODS: We evaluated the psychometric characteristics of the Spanish version of the ABOS in a clinical ED sample (239 caregivers of 143 ED patients). Instrument reliability (internal consistency), validity (construct, convergent and discriminant, known groups), responsiveness and goodness-of-fit were measured. RESULTS: Data from the Spanish population revealed a three-factor structure similar to that of the original ABOS, although the composition of subscales differed somewhat from the original. An ABOS cut-point of 21 was identified. The Cronbach's alpha coefficient for the total ABOS score was 0.81. Correlations with other instruments demonstrated convergent and divergent validity. Among caregivers, the total ABOS score and Factor scores significantly discriminated between anxiety, depression and health-related quality of life, while among ED patients they discriminated between diagnosis, severity and level of ED symptoms - evidence of known-groups validity. CONCLUSION: These findings suggest that the ABOS can be reliably and validly used in Spain in a number of different clinical contexts, by researchers and clinicians alike.

Acute adverse reactions to iopromide vs iomeprol: a retrospective analysis of spontaneous reporting from a radiology department.

OBJECTIVE: To compare the safety of iopromide and iomeprol use in a hospital that switched from the former to the latter and found an apparent increase in the number (and a different profile) of adverse reactions reported for iomeprol, putting the safety of its use into question. METHODS: This was a retrospective study of cases of acute reactions to iopromide and iomeprol reported in two successive time periods. Data from examinations using iopromide (62539 CT scans and 10348 urography scans) and iomeprol (34308 CT scans and 2846 urography scans) were obtained from the computer system of the hospital. RESULTS: For each period, 154 cases of reactions were reported for iopromide and 86 for iomeprol, being severe in 10 (6.5%) patients for iopromide vs 17 (19.8%) patients for iomeprol; a statistically significant difference of p<0.003 was recorded. The most frequent adverse reactions (%/%) for iopromide/iomeprol were urticaria (29.1/17.2), pruritus (22.6/15.6), upper respiratory tract signs and symptoms (12.1/16.7), oedema (4.3/0), erythemas (3.4/5.0), nausea or vomiting (1.2/11.7) and chest pain (0/3.9) (p<0.0001 for the global comparison). The distribution of the reactions (%/%) by System Organ Class for iopromide/iomeprol was skin (56.7/41.1), respiratory (19.2/26.7), vascular (6.8/2.2), general (5.3/7.2), gastrointestinal (4.6/15.0) and others (7.4/7.9) (p<0.0002 for the global comparison). CONCLUSION: Adverse reactions were more severe for iomeprol. Skin and vascular reactions with no chest pain were more frequent for iopromide, whereas gastrointestinal reactions were more frequent for iomeprol. ADVANCES IN KNOWLEDGE: Comparative studies of media contrast safety are scarce and summary information on product characteristics is insufficient. This study showed the differences in severity and profile of adverse reactions between iopromide and iomeprol.

Relationship of sociodemographic variables with outcomes after cataract surgery.

PURPOSE: The objective of this study is to analyse the relationship between sociodemographic characteristics of patients undergoing cataract extraction and their outcomes. METHODS: The method comprised a prospective cohort study of patients recruited from 17 hospitals of different areas of Spain. Data gathered before surgery included sociodemographic variables, visual acuity, and visual function (using the Visual Function Index-14). After surgery, we assessed visual acuity and visual function at 6 weeks and at 3 months, respectively. Multivariate multilevel analysis was performed to assess the relationship of sociodemographic variables with changes in visual acuity and function, analysing whether improvements surpassed the minimal clinically important differences (MCIDs). RESULTS: Multivariate analysis showed that for visual acuity, (i) older men had a lower odds ratio (OR) of surpassing the MCID (OR: 65-75 years, 0.64; >75 years, 0.51); (ii) those with primary (1.65) or secondary (1.41) education had higher ORs than those with no formal education; and (iii) those living in a residential home had a lower OR than men living alone (0.36). In women, we found that the higher the educational level, the greater the improvement in visual acuity (primary, 1.41; secondary, 1.76), whereas socially dependent women (0.70) were less likely to exceed the MCID. With regards to predictors related to achievement of an MCID in visual function, only dependency was associated with more improvement in men (OR: 1.39), whereas in women the educational level was the only predictor (primary: 0.72; secondary: 0.61). CONCLUSIONS: This study found that patients with certain sociodemographic characteristics were less likely to experience an MCID in visual acuity or visual function after cataract surgery.

Explicit criteria for hospital admission in exacerbations of chronic obstructive pulmonary disease.

OBJECTIVE: To develop detailed, explicit criteria for determining the appropriateness of admission for patients with exacerbations of chronic obstructive pulmonary disease (COPD). DESIGN: Using a modified Delphi process, a panel of seven pneumologists and five emergency department (ED) physicians was assembled to establish the appropriateness of hospital admission for 896 distinct theoretical scenarios. To assess the reliability of the criteria, a second national panel of five pneumologists and five ED physicians was assembled. We examined the influence of all variables on the first panel score using linear regression models. The explicit criteria developed were summarised by classification and regression tree analysis. RESULTS: The appropriateness of the hospitalisation scenarios increased with the severity of COPD. The kappa of agreement between the two panels was 0.79. Predictors of appropriate hospitalisation were severity of current COPD exacerbation, response to previous treatment and expected adherence to treatment. The panel results were synthesised and presented in three decision trees. Misclassification error in the decision trees, as compared with the panel's original ratings, was 6.1%. CONCLUSIONS: These explicit criteria can be used to help determine the appropriateness of admission for patients with exacerbations of COPD.
