Transforming a public university hospital and its area of influence into a comprehensive resource in response to the COVID-19 pandemic.

INTRODUCTION AND OBJECTIVES: The outbreak of COVID-19 has overwhelmed healthcare systems all over the world. The aim of this article is to describe the process of transforming the Vall d'Hebron University Hospital, the second largest hospital in Spain, into a COVID-19 centre coordinating response to the pandemic in its reference area. MATERIALS AND METHODS: The study draws on the experience of the authors in transforming the hospital into a comprehensive resource in response to the COVID-19 pandemic. The strategy is based on four central strategies: early planning, coordination of all healthcare agents in its reference area, definition of clear leadership roles, and the organisation of care based on multidisciplinary teams with minimal recruitment of new staff. RESULTS: The transformation strategy enabled the hospital to cope with the surge in patients without exceeding its capacity. During the response phases, which amounted to a period of 57 days, 3106 patients consulted the ER and 2054 were admitted, 346 of whom were treated at the ICU. To accommodate the number of adult COVID-19 patients, adult ICU availability was progressive increased by 371%, and ordinary beds increased by 240. A total of 671 staff members went on sick leave after testing positive for COVID-19. CONCLUSION: The transformation experience of the hospital provides insight into how effectively adapt the structures and functioning of large hospitals. The relevance of territorial coordination during the pandemic is stressed as an effective strategy that contributed coping the pandemic.

Pneumococcal serotypes in children, clinical presentation and antimicrobial susceptibility in the PCV13 era.

The aim was to analyse invasive pneumococcal disease (IPD) serotypes in children aged ⩽17 years according to clinical presentation and antimicrobial susceptibility. We conducted a prospective study (January 2012-June 2016). IPD cases were diagnosed by culture and/or real-time polymerase chain reaction (PCR). Demographic, microbiological and clinical data were analysed. Associations were assessed using the odds ratio (OR) and 95% confidence intervals (CI). Of the 253 cases, 34.4% were aged <2 years, 38.7% 2-4 years and 26.9% 5-17 years. Over 64% were 13-valent pneumococcal conjugate vaccine (PCV13) serotypes. 48% of the cases were diagnosed only by real-time PCR. Serotypes 3 and 1 were associated with complicated pneumonia (P < 0.05) and non-PCV13 serotypes with meningitis (OR 7.32, 95% CI 2.33-22.99) and occult bacteraemia (OR 3.6, 95% CI 1.56-8.76). Serotype 19A was more frequent in children aged <2 years and serotypes 3 and 1 in children aged 2-4 years and 5-17 years, respectively. 36.1% of cases were not susceptible to penicillin and 16.4% were also non-susceptible to cefotaxime. Serotypes 14, 24F and 23B were associated with non-susceptibility to penicillin (P < 0.05) and serotypes 11, 14 and 19A to cefotaxime (P < 0.05). Serotype 19A showed resistance to penicillin (P = 0.002). In conclusion, PCV13 serotypes were most frequent in children aged ⩽17 years, mainly serotypes 3, 1 and 19A. Non-PCV13 serotypes were associated with meningitis and occult bacteraemia and PCV13 serotypes with pneumonia. Non-susceptibility to antibiotics of non-PCV13 serotypes should be monitored.

Arteritis temporal e ictus: análisis de 6 casos / Stroke and temporal arteritis: A study of 6 cases

INTRODUCCIÓN: Aunque la asociación de arteritis de la temporal e ictus isquémico no es frecuente, su diagnóstico y su manejo posterior plantean serias dificultades, requiriendo un alto índice de sospecha. MÉTODOS: Analizamos una serie de 6 pacientes con arteritis de la temporal confirmada por biopsia con ictus isquémico como forma de presentación. Discutimos las características clínicas y las dificultades en su valoración, su evolución a corto y largo plazo, el tratamiento realizado y la utilidad de las nuevas pruebas diagnósticas. RESULTADOS: Nuestra serie de 6 pacientes tenía una edad media de 68,3 años y el 50% eran mujeres. La mayoría de los pacientes asociaba síntomas sistémicos. No hubo diferencias en la afectación de territorio anterior y posterior. La RM y angio, el Doppler y la PET-TAC fueron muy útiles en el diagnóstico y la orientación terapéutica de los pacientes. El seguimiento medio fue de 26 meses y la evolución distó de ser benigna: el 33% quedó con Rankin ≥ 3, falleciendo un paciente. Además, 2 pacientes, tratados con corticoides a dosis plena, tuvieron nuevos ictus. Dos pacientes fueron tratados con angioplastia. CONCLUSIONES: El ictus provocado por la arteritis de células gigantes es una enfermedad potencialmente grave, que requiere una alta sospecha diagnóstica y un tratamiento corticoideo temprano. Los nuevos métodos diagnósticos ayudan a refinar la correcta evaluación de los pacientes y a determinar el tratamiento óptimo. El tratamiento endovascular puede ser una opción terapéutica válida en casos seleccionados

INTRODUCTION: Though uncommon, ischaemic stroke due to temporal arteritis carries serious difficulties for diagnosis and subsequent management and requires a high level of suspicion. METHODS: We analysed a series of 6 patients with biopsy-proven temporal arteritis presenting with ischaemic stroke. We discuss clinical characteristics, difficulties of assessment, short- and long-term progression, treatment, and the usefulness of new diagnostic techniques. RESULTS: Our sample of 6 patients had a mean age of 68.3 years; 50% were women. The majority of patients showed systemic symptoms. Anterior and posterior circulation were affected similarly. MRI angiography, Doppler sonography, and PET-CT proved to be very useful for diagnosis and treatment. Mean follow-up time was 26 months. Clinical outcomes were far from good: 33% scored ≥ 3 on the modified Rankin scale, including one death. Two patients had recurrent stroke despite treatment with full doses of corticosteroids, and 2 underwent angioplasty. CONCLUSIONS: Stroke caused by giant cell arteritis is a serious and potentially severe condition which requires a high level of suspicion and early treatment with corticosteroids. New diagnostic techniques contribute to refining patient assessment and identifying the optimal treatment. Endovascular treatment may be a valid therapeutic option in selected patients

Individualized and Standardized Outcome Measures: Further Arguments in Favor of Cohabitation.

Ashworth et al. (Admin Policy Ment Health Ment Health Serv Res 46:425-428, 2019) recently published a paper in this journal making a cogent argument for the cohabitation of standardized and individualized outcome measures. In the present Point of View article, we consider additional arguments in favor of this cohabitation.

The situation of vaccines for the prevention of infections in adults: An opinion paper on the situation in Spain.

The childhood immunization schedule is well known and generally well implemented in developed countries. For various reasons, the same is not true of vaccines aimed at preventing infections in adults, in which vaccination coverage is incomplete and generally very deficient. In order to assess the situation of adult vaccination in Spain, the Fundación de Ciencias de la Salud has brought together a series of experts in different fields, including doctors, nurses, representatives of patient associations, health managers and economists, health authorities and journalists to deal with this issue. The format was that of a round table in which a series of questions previously formulated by the coordinators were to be answered and debated. The document presented is not an exhaustive review of the topic, nor is it intended to make recommendations, but only to give a multidisciplinary opinion on topics that could be particularly debatable or controversial. The paper reviews the main vaccine-preventable adult diseases, their clinical and economic impact, the possibilities of reducing them with vaccination programmes and the difficulties in carrying them out. The role of nursing, pharmacy services, patient associations and the health administration itself in changing the current situation was discussed. Prospects for new vaccines were discussed and we speculated on the future in this field. Finally, particularly relevant ethical aspects in decision-making regarding vaccination were discussed, which must be faced by both individuals and states. We have tried to summarize, at the end of the presentation of each question, the environment of opinion that was agreed with all the members of the table.

Extensively drug-resistant Pseudomonas Aeruginosa outbreak in a burn unit: management and solutions.

Infections are still the main cause of mortality in burn patients. Multidrug resistant bacteria can cause outbreaks in critical care and burn units. We describe an outbreak of infection by extensively drug-resistant Pseudomonas aeruginosa in the Burn Unit of a University Hospital in Barcelona (Spain) between April and July 2016. A descriptive study of all cases, a bacterial colonization screening of all admitted patients and a microbiological environmental study were performed in order to detect a possible common focus. Contact isolation and cohortization of healthcare workers of all infected or colonized patients were applied. Environmental control measures were instituted for possible sources of infection. The outbreak was caused by a strain of P. aeruginosa only sensitive to colistin. Ten patients were infected or colonized and two of them died. The same strain was detected in several taps and drains in different rooms of the Unit. After applying control measures, changing faucets and drains, carrying out thermal disinfection of the hot water installation of the unit, disinfecting the rooms with ultraviolet radiation and placing antibacterial filtration devices in all the taps among other measures, an effective control of the outbreak was achieved.

Les infections sont toujours une cause majeure de mortalité chez les brûlés. Des épidémies à bactéries multirésistantes (BMR) dans les CTB sont régulièrement rapportées. Nous décrivons une épidémie due à Pseudomonas æruginosa BMR, sensible uniquement à la colimycine, survenue dans le CTB d'un hôpital universitaire de Barcelone entre avril et juillet 2016. Elle a touché 10 patients dont 2 sont morts. Une étude de chaque cas, un dépistage chez tous les entrants et une étude environnementale ont été réalisées, afin de trouver d'éventuelles similitudes. Un isolement contact et un cohorting ont été mis en place. Des mesures de contrôle de l'environnement ont été implémentées. La souche incriminée a été retrouvée dans plusieurs robinets et siphons du service. Cette épidémie a été résolue après, outre les mesures précitées, changement des robinets et des siphons (avec mise en place d'ultrafiltres sur les robinets), choc thermique du réseau d'adduction d'eau, désinfection terminale UV des chambres.

Assessing prediction accuracy for outcomes of ventilator-associated events and infections in critically ill children: a prospective cohort study.

OBJECTIVES: To assess the prediction accuracy of the 2008 US Centers for Disease Control and Prevention (CDC) definitions for ventilator-associated pneumonia (VAP)/ventilator-associated tracheobronchitis (VAT), 2013 CDC definitions for ventilator-associated events (VAE) and a new VAE algorithm in the paediatric (Ped) population, the Ped-VAE. METHODS: We performed a prospective 13-month cohort study at a multidisciplinary paediatric intensive care unit (PICU). Primary endpoints were duration of ventilation episode, PICU or hospitalization length of stay from episode and episode mortality. Episodes without VAE (or VAP/VAT) served as comparison groups. RESULTS: One hundred eight episodes of ventilation (99 children) with 2554 ventilator-days were assessed. In episodes not meeting 2008 CDC definitions, a median of 6 ventilator-days (PICU stay 11 days) was documented (with eight deaths), not significantly different from episodes not meeting VAE or Ped-VAE definitions. Using 2008 CDC criteria, 11 (10.2%) respiratory infections (eight tracheobronchitis) were identified, seven VAEs using 2013 CDC criteria (6.4%) and 29 (26.8%) using Ped-VAE criteria (relative risk vs. 2008 CDC criteria 2.58; 95% confidence interval 1.36-4.91). In contrast with their comparison groups, episodes meeting 2008 CDC criteria did not significantly predict outcomes, whereas VAEs (only four possible VAPs) were associated with significantly more ventilation and PICU length of stay (12-day/8-day increase) and sevenfold increase in mortality. Ped-VAE did not increase mortality, but it was associated with 4-day increase in ventilation and PICU length of stay, with ten possible VAPs, and atelectasis (9/12) as the main paediatric ventilator-associated condition. CONCLUSIONS: The 2008 CDC criteria did not predict outcomes, whereas VAE only identified very severe events. The Ped-VAE algorithm had more accuracy predicting outcomes by characterizing lower oxygenation changes and identifying hypoxaemia severity, a major driver of management.

Serological survey of hepatitis B immunity in healthcare workers in Catalonia (Spain).

Healthcare workers (HCW) are exposed to preventable infectious diseases, notably hepatitis B (HB). The aim of this study was to determine the immunity of HCW against hepatitis B. We made a seroprevalence study using a self-administered survey and obtained blood samples. Antibodies against the HB surface antigen (anti-HBs) and against the HB core antigen (anti-HBc) were studied. The odds ratio (OR) and 95% confidence intervals (CI) were calculated. The adjusted OR were calculated using logistic regression. Of the 644 HCW who participated (29.7% physicians, 38.7% nurses, 13.4% other clinical workers and 18.3% non-clinical workers), 46.4% were primary care workers and 53.6% hospital workers. The overall prevalence of anti-HBs was 64.4%. HCW aged <25 y had a significantly higher prevalence (86.7%) than those aged 35-44 y (adjusted OR 3.40; 95% CI 1.06-10.90). The prevalence of anti-HBc was 4.1%, and increased with age. Significant differences were found for HCW aged >44 y with respect to those aged 25-34 y. 75.6% of HCW stated they were vaccinated, but only 39.3% had a vaccination card. In HCW who stated they were unvaccinated, 10.8% had a vaccinated serological pattern (anti-HBc-negative and anti-HBs -positive). Written, updated vaccination records are essential to reliably determine the vaccination status.

Association between source control and mortality in 258 patients with intra-abdominal candidiasis: a retrospective multi-centric analysis comparing intensive care versus surgical wards in Spain.

Early empiric therapy and adequate resuscitation have been identified as main predictors of outcome in patients with candidemia or bacteremia. Moreover, source control is a major determinant in infectious sites when feasible, as a main technique to reduce microbiological burden. A retrospective, multicenter, cohort study was performed at surgical wards and intensive care units (ICU) of three University Hospitals in Spain between 2010 and 2014, with the aim of improving understanding of the interaction between source control, early antifungal therapy, and use of vasoactives in patients with intra-abdominal candidiasis (IAC). Source control was defined as all physical actions taken to control a focus of infection and reduce the favorable conditions that promote microorganism growth or that maintain the impairment of host defenses. Two hundred and fifty-eight patients with IAC were identified. Sixty-one patients were at ICU for diagnosis. Mortality was higher in the ICU group compared to what was documented for the non-ICU group (35 % vs 19.5 %, p = 0011). Adequate source control within 48 h of diagnosis was achieved in 60 % of the cohort. In multivariate analysis, inadequate source control was identified as the only common risk factor for 30-day mortality in both groups (ICU group OR: 13.78 (95% CI: 2.60-72.9, p = 0.002) and non-ICU group OR: 6.53 (95% CI: 2.56-16.61, p = <0.001). The population receiving both adequate source control and adequate antifungal treatment was the one associated with a higher survival rate, in both the ICU and surgical groups. Source control remains a key element in IAC, inside and outside the intensive care unit. Early antifungal treatment among ICU patients was associated with lower mortality.

Circulation of a novel human respiratory syncytial virus Group B genotype during the 2014-2015 season in Catalonia (Spain).

Human respiratory syncytial virus (HRSV) is one of the most common viral aetiological agents in the youngest population. In the present study a novel HRSV-B BA genotype is first described based on the phylogenetic analysis of the coding hypervariable region 2 sequences of G protein from strains detected during the 2014-2015 season. Among all strains detected in the last season, 44% belonged to this new genotype. Therefore, it highlights the importance of a continuous HRSV surveillance to monitor the emergence and spread of new genotypes or variants with genetic changes that may affect antigenic and tropism features.

Prevalence of anti-rubella, anti-measles and anti-mumps IgG antibodies in neonates and pregnant women in Catalonia (Spain) in 2013: susceptibility to measles increased from 2003 to 2013.

Non-immune neonates and non-immune pregnant women are at risk of developing rubella, measles and mumps infections, including congenital rubella syndrome. We describe the seroepidemiology of measles, mumps and rubella (MMR) in neonates and pregnant women in Catalonia (Spain). Anti-rubella, anti-measles and anti-mumps serum IgG titres were assessed using enzyme-linked immunosorbent assay (ELISA) tests in 353 cord blood samples from neonates of a representative sample of pregnant women obtained in 2013. The prevalence of protective antibody titres in neonates was 96 % for rubella IgG (≥8 IU/ml), 90 % for measles IgG (>300 IU/ml) and 84 % for mumps IgG (>460 EU/ml). Slightly lower prevalences of protective IgG titres, as estimated from the cord blood titres, were found in pregnant women: 95 % for rubella IgG, 89 % for measles IgG and 81 % for mumps IgG. The anti-measles and anti-mumps IgG titres and the prevalences of protective IgG titres against measles and mumps increased significantly (p < 0.001) with maternal age. The prevalence of protective anti-measles IgG titres decreased by 7 % [odds ratio (OR) = 0.15, p < 0.001), the prevalence of protective anti-rubella IgG titres increased by 3 % (OR = 1.80, p < 0.05) and the MMR vaccination coverage (during childhood) in pregnant women increased by 54 % (OR = 2.09, p < 0.001) from 2003 to 2013. We recommend to develop an MMR prevention programme in women of childbearing age based on mass MMR vaccination or MMR screening and vaccination of susceptible women to increase immunity levels against MMR.
