Increasing Influenza Vaccination in Primary Healthcare Workers Using Solidary Incentives: Analysis of Efficacy and Costs

Introduction: Influenza vaccination campaigns have difficulty in reaching the 75% uptake in healthcare workers (HCWs) that public health organizations target. This study runs a campaign across 42 primary care centers (PCCs) where for every HCW vaccinated against influenza, a polio vaccine is donated through UNICEF for children in developing nations. It also analyses the efficacy and cost of the campaign. Method: This observational prospective non-randomized cohort study was conducted across 262 PCCs and 15.812 HCWs. A total of 42 PCCs were delivered the full campaign, 114 were used as the control group, and 106 were excluded. The vaccine uptake in HCWs within each of those PCCs was registered. The cost analysis assumes that campaign costs remain stable year to year, and the only added cost would be the polio vaccines (0.59€). Results: We found statistically significant differences between both groups. A total of 1423 (59.02%) HCWs got vaccinated in the intervention group and 3768 (55.76%) in the control group OR 1.14, CI 95% (1.04–1.26). In this scenario, each additional HCW vaccinated in the intervention group costs 10.67€. Assuming all 262 PCCs had joined the campaign and reached 59.02% uptake, the cost of running this incentive would have been 5506€. The potential cost of increasing uptake in HCWs by 1% across all PCC (n = 8816) would be 1683€, and across all healthcare providers, 8862€ (n = 83.226). Conclusions: This study reveals that influenza vaccination uptake can be innovative by including solidary incentives and be successful in increasing uptake in HCWs. The cost of running a campaign such as this one is low.

Prevalence, incidence and risk factors for acquisition and colonization of extended-spectrum beta-lactamase- and carbapenemase-producing Enterobacteriaceae from dogs attended at a veterinary hospital in Spain

The last 10 years have seen a progressive increase in antibiotic resistance rates in bacteria isolated from companion animals. Exposure of individuals to resistant bacteria from companion animals, such as extended-spectrum beta-lactamase- (ESBL) and carbapenemase- (CPE) producing Enterobacteriaceae, can be propitiated. Few studies evaluate the incidence and risk factors associated with colonization by multidrug-resistant bacteria in dogs. This work aims to estimate the prevalence, incidence and risk factors associated with colonization of ESBL-E and CPE-E in 44 canine patients hospitalized in a veterinary hospital. The antimicrobial susceptibility of Enterobacteriaceae strains was analyzed and the molecular detection of resistant genes was performed. A prevalence of 25.0% and an incidence of ESBL-E of 45.5% were observed in dogs colonized by Enterobacteriaceae at hospital admission and release, respectively. Escherichia coli, Klebsiella pneumoniae, Citrobacter koseri and Morganella morganii were identified as ESBL-producing bacterial species. Resistance genes were detected for ESBL-producing strains. No CPE isolates were obtained on the CPE-selective medium. The administration of corticosteroids prior to hospitalization and the presence of concomitant diseases were associated with colonization by these bacteria in dogs. Considering that one-quarter of the patients evaluated were colonized by ESBL-E, companion animals should be considered as potential transmission vehicles and ESBL-E reservoirs for humans. Special care should be taken in animals attended at veterinary hospitals, as the length of stay in the hospital could increase the risks.

Trends in cardiovascular care in the National Health System in Spain. Data from the RECALCAR project 2011-2020

INTRODUCTION AND OBJECTIVES

The RECALCAR project (Resources and Quality in Cardiology), an initiative of the Spanish Society of Cardiology, aims to standardize information to generate evidence on cardiovascular health outcomes. The objective of this study was to analyze trends in the resources and activity of cardiology units and/or services and to identify the results of cardiovascular care during the last decade in Spain.

METHODS

The study was based on the 2 annual data sources of the RECALCAR project: a survey on resources and activity of cardiology units and/or services (2011-2020) and the minimum data set of the National Health System (2011-2019), referring to heart failure (HF), STEMI, and non-STEMI.

RESULTS

The survey included 70% of cardiology units and/or services in Spain. The number of hospital beds and length of stay decreased, while there was a notable increase in the number of cardiac imaging studies and percutaneous therapeutic procedures performed. Age- and sex-adjusted admissions for HF tended to decrease, despite an increase in mortality and the percentage of readmissions. In contrast, the trend in mortality and readmissions was highly favorable in STEMI; in non-STEMI, although positive, the trend was less marked.

CONCLUSIONS

The information provided by the RECALCAR project shows a favorable trend in the last decade in resources, activity and results of certain cardiovascular processes and constitutes an essential source for future improvements and decision-making in health policy.

Efficiency of screening for human immunodeficiency virus infection in emergency departments: a systematic review and meta-analysis

OBJECTIVES

The rates of undiagnosed and late-diagnosed human immunodeficiency virus (HIV) infection are high. Screening for HIV infection in hospital emergency departments (EDs) could offer a way to increase the number of diagnoses. Our aim was to analyze whether universal hospital ED screening for HIV is efficient.

MATERIAL AND METHODS

We followed the guidelines for Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). PubMed, the Cochrane Library, LILACS, Scopus, EMBASE, and the Web of Science were searched using the following terms: "HIV infections/epidemiology," "AIDS serodiagnosis," "emergency service, hospital," "prevalence," and "mass screening/methods." The searches were limited to a 5-year time frame (2016-2020); only publications in English or Spanish were collected. We included studies of universal HIV screening among hospital ED patients and evaluated them using the Quality Assessment Tool for Quantitative Studies.

RESULTS

A total of 273 articles were identified. Twelve met the inclusion criteria. The studies analyzed 103 731 patient samples and yielded 652 new HIV diagnoses. A random effects model estimated an overall new-diagnosis prevalence of 0.60% (95% CI, 0.39%-0.84%). The heterogeneity statistic I2 was high, at 90.02% (P .001). Estimates of prevalence based on studies carried out in Europe, the United States, and Africa were, respectively, 0.48% (95% CI, 0.13%-1.03%), 0.54% (95% CI, 0.33%-0.40%), and 5.6% (95% CI, 3.37%-9.2%). The studies received quality ratings of moderate or strong.

CONCLUSION

Although the reviewed studies applied various screening strategies to identify new HIV diagnoses, our findings support the conclusion that universal screening is efficient.

Predictive Models for Equine Emergency Exploratory Laparotomy in Spain: Pre-, Intra-, and Post-Operative-Mortality-Associated Factors

The extrinsic and intrinsic characteristics of an equine population may influence the onset of gastrointestinal lesions and affect the survival rate of patients. The equine population in Spain has been the focus of a small number of studies, none of which have involved more than one surgical center. In this retrospective cohort study, we aimed to analyze the survival rate, identify the variables that influenced death, and generate multivariate models using clinical variables. Data were collected from the clinical records of two surgical referral centers in the same region, and a total of 566 horses met the inclusion criteria. The statistical analysis was divided into three parts: The first and second included logistic analysis, in order to identify the variables most closely associated with survival. The third part assessed all previous variables in terms of survival and hospitalization time, using a COX survival analysis. The main risk factors associated with intra-operative mortality were related to seasonality (winter and summer), patient age (older than 9 years), distance from the hospital, the presence of a strangulating lesion, and the bowel segment affected (small intestine). Furthermore, the main factors associated with mortality during hospitalization were the characteristics of the lesions (strangulating) and the differences between surgical centers. The models generated in this study have good predictive value and use only reliable and easily obtainable variables. The most reliable characteristics are those related to the type of colic and the location of the lesion.

Procalcitonin concentration in the emergency department predicts 30-day mortality in COVID-19 better than the lymphocyte count, the neutrophil-tolymphocyte ratio, or the C-reactive protein level

OBJECTIVES

Although many demographic and clinical predictors of mortality have been studied in relation to COVID-19, little has been reported about the prognostic utility of inflammatory biomarkers.

MATERIAL AND METHODS

Retrospective cohort study. All patients with laboratory-confirmed COVID-19 treated in a hospital emergency department were included consecutively if baseline measurements of the following biomarkers were on record: lymphocyte counts, neutrophil-to-lymphocyte ratio NRL, and C-reactive protein (CRP) and procalcitonin (PCT) levels. We analyzed associations between the biomarkers and all-cause 30-day mortality using Cox regression models and dose-response curves.

RESULTS

We included 896 patients, 151 (17%) of whom died within 30 days. The median (interquartile range) age was 63 (51-78) years, and 494 (55%) were men. NLR, CRP and PCT levels at ED presentation were higher, while lymphocyte counts were lower, in patients who died compared to those who survived (P .001). The areas under the receiver operating characteristic curves revealed the PCT concentration (0.79; 95% CI, 0.75-0.83) to be a better predictor of 30-day mortality than the lymphocyte count (0.70; 95% CI, 0.65-0.74; P .001), the NLR (0.74; 95% CI, 0.69-0.78; P = .03), or the CRP level (0.72; 95% CI, 0.68-0.76; P .001). The proposed PCT concentration decision points for use in emergency department case management were 0.06 ng/L (negative) and 0.72 ng/L (positive). These cutoffs helped classify risk in 357 patients (40%). Multivariable analysis demonstrated that the PCT concentration had the strongest association with mortality.

CONCLUSION

PCT concentration in the emergency department predicts all-cause 30-day mortality in patients with COVID-19 better than other inflammatory biomarkers.

RECALSEEN. Subgroup: Patient care in the clinical nutrition units of the Spanish National Health System

INTRODUCTION

Artificial nutrition (AI) is one of the most representative examples of coordinated therapeutic programs, and therefore requires adequate development and organization. The first clinical nutrition units (CNUs) emerged in the public hospitals of the Spanish National Health System (NHS) in the 80s and have gradually been incorporated into the departments of endocrinology and nutrition (DENs). The purpose of our article is to report on the results found in the RECALSEEN study as regards the professional and organizational aspects relating to CNUs and their structure and operation.

MATERIALS AND METHODS

Data were collected from the RECALSEEN study, a cross-sectional, descriptive study of the DENs in the Spanish NHS in 2016. The survey was compiled from March to September 2017. Qualitative variables were reported as frequency distributions (number of cases and percentages), and quantitative variables as the mean, median, and standard deviation (SD).

RESULTS

A total of 88 (70%) DENs, out of a total of 125 general acute hospitals of the NHS with 200 or more installed beds, completed the survey. CNUs were available in 83% of DENs (98% in hospitals with 500 or more beds). As a median, DENs had one nurse dedicated to nutrition (35% did not have this resource). Fifty-three percent of DENs with nutrition units had dieticians integrated into the unit (median: 1). DENs located in hospitals with 500 or more beds are more complex and have a wide portfolio of monographic unit services (morbid obesity, 78.3%; artificial home nutrition, 87%; chronic diseases, 65.2%) and specific techniques (impedanciometry, 78%). However, only 14% of the centers perform universal screening tests for malnutrition, and a secondary diagnosis of malnutrition only appears in 12.3 reports per 1000 hospital discharges.

DISCUSSION

After the 1997 and 2003 studies, the results of 2017 show a marked growth and consolidation of CNUs within the DENs in most hospitals. Today, the growth of this specialty is largely due to the care demand created by hospital clinical nutrition. CNUs still have an insufficient nursing staff and dietitians/nutritionists, and in the latter case, atypical contracts or grants funded by research projects or the pharmaceutical industry are common. Units for specific nutritional diseases and participation in multidisciplinary groups, quite heterogeneous, are concentrated in hospitals with 500 or more beds and represent an excellent opportunity for CNU development.

CONCLUSIONS

Many DENs of Spanish hospitals include CNUs where care is provided by endocrinologists, who devote most of their time to clinical nutrition in more than half of the hospitals. This is most common in large centers with a high workload in relation to staffing. There is considerable heterogeneity between hospitals in terms of both the number and type of activity of the CNUs.

Thirty-day outcomes in frail older patients discharged home from the emergency department with acute heart failure: effects of high-risk criteria identified by the DEED FRAIL-AHF trial

OBJECTIVES

To study the effect of high-risk criteria on 30-day outcomes in frail older patients with acute heart failure (AHF) discharged from an emergency department (ED) or an ED's observation and short-stay areas.

MATERIAL AND METHODS

Secondary analysis of discharge records in the Older AHF Key Data registry. We selected frail patients (aged > 70 years) discharged with AHF from EDs. Risk factors were categorized as modifiable or nonmodifiable. The outcomes were a composite endpoint for a cardiovascular event (revisits for AHF, hospitalization for AHF, or cardiovascular death) and the number of days alive out-of-hospital (DAOH) within 30 days of discharge.

RESULTS

We included 380 patients with a mean (SD) age of 86 (5.5) years (61.2% women). Modifiable risk factors were identified in 65.1%, nonmodifiable ones in 47.8%, and both types in 81.6%. The 30-day cardiovascular composite endpoint occurred in 83 patients (21.8%). The mean 30-day DAOH observed was 27.6 (6.1) days. Highrisk factors were present more often in patients who developed the cardiovascular event composite endpoint: the rates for patients with modifiable, nonmodifiable, or both types of risk were, respectively, as follows in comparison with patients not at high risk: 25.0% vs 17.2%, P = .092; 27.6% vs 16.7%, P = .010; and 24.7% vs 15.2%, P = .098). The 30-day DAOH outcome was also lower for at-risk patients, according to type of risk factor present: modifiable, 26.9 (7.0) vs 28.4 (4.4) days, P = .011; nonmodifiable, 27.1 (7.0) vs 28.0 (5.0) days, P = .127; and both, 27.1 (6.7) vs 28.8 (3.4) days, P = .005). After multivariate analysis, modifiable risk remained independently associated with fewer days alive (adjusted absolute difference in 30-day DAOH, -1.3 days (95% CI, -2.7 to -0.1 days). Nonmodifiable factors were associated with increased risk for the 30-day cardiovascular composite endpoint (adjusted absolute difference, 10.4%; 95% CI, -2.1% to 18.7%).

CONCLUSION

Risk factors are common in frail elderly patients with AHF discharged home from hospital ED areas. Their presence is associated with a worse 30-day prognosis.

Caseload and cardiopulmonary arrest management by an out-of-hospital emergency service during the COVID-19 pandemic

OBJECTIVES

To describe the effect of the coronavirus disease 2019 (COVID-19) pandemic on the initiation of cardiopulmonary resuscitation (CPR) in patients with out-of-hospital cardiopulmonary arrest. To compare the cardiopulmonary arrest caseload during the pandemic to the caseloads in other periods.

MATERIAL AND METHODS

Observational, prospective study based on the registry of out-of-hospital cardiopulmonary arrest emergencies the SUMMA112 ambulance service responded to between March 1 and April 30, 2020, in the Spanish autonomous community of Madrid. The registry is a Utstein-style database. The period of March-April 2019 was the control period for direct comparison with the 2020 study period and with the January-February periods of 2019 and 2020.

RESULTS

The responders undertook advanced CPR in 146 of the 313 cardiopulmonary arrest cases registered during March-April, 2020. Of the 87 patients with COVID-19-positive tests, 33 reached the hospital alive. Advanced CPR was not applied in 167 cases; the most frequent reason was prolonged circulatory collapse. Most cases (92.7%) occurred in the home. The emergency dispatchers received more calls in March and April of 2020, but they sent out a similar number of ambulances.

CONCLUSION

Mortality was higher in cases of cardiopulmonary arrest during the COVID-19 pandemic. The percentage of cases with no application of advanced CPR rose; the main reason was the amount of time between collapse and first response. Even though the number of emergency calls increased significantly, the SUMMA112 service did not dispatch more ambulances.

Complications and outcomes of cats with coxofemoral luxation treated with hip toggle stabilization using ultrahigh-molecular-weight-polyethylene or nylon (2009-2018): 48 cats

OBJECTIVE

To report overall rate and type of complications and outcomes of cats with coxofemoral luxation managed with hip toggle stabilization (HTS), to compare rate of postoperative complications and outcomes of cats treated with ultrahigh-molecular-weight-polyethylene (UHMWPE) or nylon, and to identify risk factors for reluxation and non-excellent outcomes.

STUDY DESIGN

Multi-institutional retrospective cohort study.

SAMPLE POPULATION

Forty-eight client-owned cats.

METHODS

Medical records of cats that underwent HTS from 2008-2018 using UHMWPE or nylon were reviewed. Univariable and multivariable logistic regression was performed to assess for factors associated with reluxation and non-excellent outcome. Final outcome was obtained from owner questionnaire.

RESULTS

Intraoperative and postoperative complications were recorded in two (4.2%) and 11 (24.4%) cats, respectively. The most common postoperative complication was reluxation (n = 5 [11.1%]). Outcome was classified as excellent in 81.1% and good in 16.2% of cats after a median of 445.5 days (range, 53-3720). No difference in rate of complications or outcomes was identified between UHMWPE and nylon. Performance of additional orthopedic procedures, occurrence of intraoperative complications, and non-performance of capsulorrhaphy were associated with reluxation. Performance of additional non-hip procedures (orthopedic/nonorthopedic) was associated with non-excellent outcome.

CONCLUSION

Hip toggle stabilization was associated with a low rate of intraoperative complications and reluxation and excellent long-term outcomes in most cats. No difference in rate of postoperative complications or outcomes of cats treated using UHMWPE or nylon was identified. Cats that underwent additional orthopedic procedures had greater risk of reluxation.

CLINICAL SIGNIFICANCE

Hip toggle stabilization is an effective technique for management of coxofemoral luxation in cats. Comparable results are expected using UHMWPE or nylon.

Incidence, clinical, risk factors and outcomes of Guillain-Barré in Covid-19

We diagnosed 11 Guillain-Barré syndrome (GBS) cases among 71,904 COVID patients attended at 61 Spanish emergency departments (EDs) during the 2-month pandemic peak. The relative frequency of GBS among ED patients was higher in COVID (0.15‰) than non-COVID (0.02‰) patients (odds ratio [OR] = 6.30, 95% confidence interval [CI] = 3.18-12.5), as was the standardized incidence (9.44 and 0.69 cases/100,000 inhabitant-years, respectively, OR = 13.5, 95% CI = 9.87-18.4). Regarding clinical characteristics, olfactory-gustatory disorders were more frequent in COVID-GBS than non-COVID-GBS (OR = 27.59, 95% CI = 1.296-587) and COVID-non-GBS (OR = 7.875, 95% CI = 1.587-39.09) patients. Although COVID-GBS patients were more frequently admitted to intensive care, mortality was not increased versus control groups. Our results suggest SARS-CoV-2 could be another viral infection causing GBS. ANN NEUROL 2021;89:598-603.

Diagnostic groups and short-term outcomes in suspected COVID-19 cases treated in an emergency department

OBJECTIVES

The primary objective was to describe the clinical characteristics and 30-day mortality rates in emergency department patients with coronavirus disease 2019 (COVID-19) in different diagnostic groupings.

MATERIAL AND METHODS

Secondary analysis of the COVID-19 registry compiled by the emergency department of Hospital Clínico San Carlos in Madrid, Spain. We selected suspected COVID-19 cases treated in the emergency department between February 28 and March 31, 2020. The cases were grouped as follows: 1) suspected, no polymerase chain reaction (PCR) test (S/no-PCR); 2) suspected, negative PCR (S/PCR-); 3) suspected, positive PCR (S/PCR+); 4) highly suspected, no PCR, or negative PCR (HS/no or PCR-); and 5) highly suspected, positive PCR (HS/PCR+). We collected clinical, radiologic, and microbiologic data related to the emergency visit. The main outcome was 30-day all-cause mortality. Secondary outcomes were hospitalization and clinical severity of the episode.

RESULTS

A total of 1993 cases (90.9%) were included as follows: S/no-PCR, 17.2%; S/PCR-, 11.4%; S/PCR+, 22.1%; HS/no PCR or PCR-, 11.7%; and HS/PCR+, 37.6%. Short-term outcomes differed significantly in the different groups according to demographic characteristics; comorbidity and clinical, radiographic, analytical, and therapeutic variables. Thirty-day mortality was 11.5% (56.5% in hospitalized cases and 19.6% in cases classified as severe). The 2 HS categories and the S/PCR+ category had a greater adjusted risk for 30-day mortality and for having a clinically severe episode during hospitalization in comparison with S/PCR- cases. Only the 2 HS categories showed greater risk for hospitalization than the S/PCR- cases.

CONCLUSION

COVID-19 diagnostic groups differ according to clinical and laboratory characteristics, and the differences are associated with the 30-day prognosis.

Chronic thromboembolic pulmonary hypertension in Spain: a decade of change

INTRODUCTION AND OBJECTIVES

Chronic thromboembolic pulmonary hypertension (CTEPH) treatment has evolved in the last decade. However, there is scarce information on the long-term impact of this progress in a real-life population at a national level. This study was designed to analyze the characteristics of CTEPH patients in Spain over the last decade.

METHODS

We prospectively collected epidemiological, clinical, and prognostic data from CTEPH patients consecutively included in the Spanish REHAP registry from January 1, 2007, to December 31, 2018. We evaluated differences over time, establishing 2013 as the reference date for analysis. Propensity scores for interventional treatment were calculated using a multivariable logistic regression model.

RESULTS

A total of 1019 patients were included; 659 (64.4%) were evaluated at a national CTEPH center. Overall, 350 patients (34.3%) were selected for surgery and 97 (9.6%) for percutaneous treatment. Patients diagnosed between 2007 and 2012 died more frequently than those diagnosed from 2013 onward (HR, 1.83; 95%CI, 1.07-3.15; P=.027). Within the subgroup of patients adjusted by propensity score, baseline pulmonary vascular resistance and the 6-minute walk test distance also determined the outcome (HR, 1.24; 95%CI, 1.15-1.33; P=.011; and HR, 0.93; 95%CI, 0.90-0.97; P=.001, respectively). High survival rates were found in patients who underwent an invasive procedure (pulmonary endarterectomy or balloon pulmonary angioplasty).

CONCLUSIONS

CTEPH diagnosis and prognosis have consistently improved in the last decade. Baseline disease severity determines the risk profile. Patients who undergo pulmonary endarterectomy or balloon pulmonary angioplasty have better outcomes.

Temporal trends and prognostic impact of length of hospital stay in uncomplicated ST-segment elevation myocardial infarction in Spain

INTRODUCTION AND OBJECTIVES

There are few data on the safety of length of stay in uncomplicated ST-segment elevation myocardial infarction. We studied trends in hospital stay and the safety of short (≤ 3 days) vs long hospital stay in Spain.

METHODS

Using data from the Minimum Basic Data Set, we identified patients with uncomplicated ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention and who were discharged alive between 2003 and 2015. The mean length of stay was adjusted by multilevel Poisson regression with mixed effects. The effect of short length of stay on 30-day readmission for cardiac diseases was evaluated in episodes from 2012 to 2014 by propensity score matching and multilevel logistic regression. We also compared risk-standardized readmissions for cardiac diseases and mortality rates.

RESULTS

The adjusted length of stay decreased significantly (incidence rate ratio <1; P <.001) for each year after 2003. Short length of stay was not an independent predictor of 30-day readmission (OR, 1.10; 95%CI, 0.92-1.32) or mortality (OR, 1.94; 95%CI, 0.93-14.03). After propensity score matching, no significant differences were observed between short and long hospital stay (OR, 1.26; 95%CI, 0.98-1.62; and OR, 1.50; 95%CI, 0.48-5.13), respectively. These results were confirmed by comparisons between risk-standardized readmissions for cardiac disease and mortality rates, except for the 30-day mortality rate, which was significantly higher, although probably without clinical significance, in short hospital stays (0.103% vs 0.109%; P <.001).

CONCLUSIONS

In Spain, hospital stay ≤ 3 days significantly increased from 2003 to 2015 and seems a safe option in patients with uncomplicated ST-segment elevation myocardial infarction.

180-Day functional decline among older patients attending an emergency department after a fall

OBJECTIVES

To determine functional changes and factors affecting 180-day functional prognosis among older patients attending a hospital emergency department (ED) after a fall.

STUDY DESIGN

Retrospective analysis from a prospective cohort study (FALL-ER Registry) spanning one year that included individuals aged ≥65 years attending four Spanish EDs after a fall. We collected 9 baseline and 6 fall-related factors.

MAIN OUTCOME MEASURES

Barthel Index (BI) was measured at baseline, discharge and 30, 90 and 180 days after the index fall. Absolute and relative BI changes were calculated. Absolute difference of ≥10 points between BI at baseline and at 180 days was considered a clinically significant functional decline.

RESULTS

452 patients (mean age 80 ± 8 years; 70.8% women) were included. Baseline BI was 79.3 ± 23.1 points. Compared with baseline, functional status was significantly lower at the 4 follow-up time points (-8.7% at discharge; and -6.9%, -7.9% and -9.5% at 30, 90 and 180 days; p < 0.001 for all comparisons in relation to baseline; p = 0.001 for change over time). One hundred and thirty-three (29.6%) patients had a clinically significant functional decline at 180 days. Age ≥85 years (OR = 2.24, 95%CI 1.23-4.08; p = 0.008), fall-related fracture (OR = 2.45, 95%CI 1.43-4.28; p = 0.001), hospitalization (OR = 1.91; 95%CI 1.11-3.29; p = 0.019) and post-fall syndrome (OR = 1.77, 95%CI 1.13-2.77; p = 0.013) were independently associated with 180-day clinically significant functional decline.

CONCLUSION

Patients ≥65 years attending EDs after a fall experience a consistent and persistent negative impact on their functional status. Several factors may help identify patients at increased risk of functional impairment.

Effect of risk of malnutrition on 30-day mortality among older patients with acute heart failure in Emergency Departments

BACKGROUND

Little is known about the prevalence and impact of risk of malnutrition on short-term mortality among seniors presenting with acute heart failure (AHF) in emergency setting. The objective was to determine the impact of risk of malnutrition on 30-day mortality risk among older patients who attended in Emergency Departments (EDs) for AHF.

MATERIAL AND METHODS

We performed a secondary analysis of the OAK-3 Registry including all consecutive patients ≥65 years attending in 16 Spanish EDs for AHF. Risk of malnutrition was defined by the Mini Nutritional Assessment Short Form (MNA-SF) < 12 points. Unadjusted and adjusted logistic regression models were used to assess the association between risk of malnutrition and 30-day mortality.

RESULTS

We included 749 patients (mean age: 85 (SD 6); 55.8% females). Risk of malnutrition was observed in 594 (79.3%) patients. The rate of 30-day mortality was 8.8%. After adjusting for MEESSI-AHF risk score clinical categories (model 1) and after adding all variables showing a significantly different distribution among groups (model 2), the risk of malnutrition was an independent factor associated with 30-day mortality (adjusted OR by model 1 = 3.4; 95%CI 1.2-9.7; p = .020 and adjusted OR by model 2 = 3.1; 95%CI 1.1-9.0; p = .033) compared to normal nutritional status.

CONCLUSIONS

The risk of malnutrition assessed by the MNA-SF is associated with 30-day mortality in older patients with AHF who were attended in EDs. Routine screening of risk of malnutrition may help emergency physicians in decision-making and establishing a care plan.

Uncontrolled donation after circulatory death: A cohort study of data from a long-standing deceased-donor kidney transplantation program

Despite good long-term outcomes of kidney transplants from controlled donation after circulatory death (DCD) donors, there are few uncontrolled DCD (uDCD) programs. This longitudinal study compares outcomes for all uDCD (N = 774) and all donation after brain death (DBD) (N = 613) kidney transplants performed from 1996 to 2015 at our center. DBD transplants were divided into those from standard-criteria (SCD) (N = 366) and expanded-criteria (N = 247) brain-dead donors (ECD). One-, 5-, and 10-year graft survival rates were 91.7%, 85.7%, and 80.6% for SCD; 86.0%, 75.8%, and 61.4% for ECD; and 85.1%, 78.1%, and 72.2% for uDCD, respectively. Graft survival was worse in recipients of uDCD kidneys than of SCD (P = .004) but better than in transplants from ECD (P = .021). The main cause of graft loss in the uDCD transplants was primary nonfunction. Through logistic regression, donor death due to pulmonary embolism (OR 4.31, 95% CI 1.65-11.23), extrahospital CPR time ≥75 minutes (OR1.94, 95%CI 1.18-3.22), and in-hospital CPR time ≥50 minutes (OR 1.79, 95% CI 1.09-2.93) emerged as predictive factors of primary nonunction. According to the outcomes of our long-standing kidney transplantation program, uDCD could help expand the kidney donor pool.

Body fat anthropometric indexes: Which of those identify better high cardiovascular risk subjects? A comparative study in Spanish population

Aim

To determine the association of body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR), waist to height ratio (WHtr) and Body Shape Index (ABSI) with high cardiovascular risk (CVR), as well as to determine whether how strong are these relationships.

Material and methods

A cross-sectional study was carried out in Spanish Caucasian adults. 3,456 subjects completed the study, 45.78% males, aged < 65 years and non-diabetic subjects. Anthropometric/biochemical variables were measured. We determined ABSI based on WC adjusted for height and weight. High CVR was defined as ≥ 20% according to the Framingham chart, ≥ 5% with the SCORE chart, and ≥ 7.5% with the ACC/AHA guide. Areas under the receiver operating characteristic curves (AUCs) were estimated for each anthropometric measure.

Results

Most significant AUCs in males were: WHtr and ABSI for Framingham ≥ 20% and SCORE ≥ 5%. Also significant were WHtr, WC and ABSI for ACCA/AHA ≥ 7.5%. On the other hand, most significant AUCs in females were: WHtr and WC for Framingham ≥ 20%; and WHtr and WHR for SCORE ≥ 5%, WHtr, and WC for ACC/AHA guide ≥ 7.5%.

Conclusions

Overall, the best anthropometric index identifying Spanish males and females who are at high risk for CV events is WHtr. ABSI was also found to be a good anthropometric index to predict high CVR in Spanish males according to FR, SCORE and ACC/AHA charts. For Spanish females, WC is a good anthropometric index according to FR and ACC/AHA guide, while WHR is better according to SCORE.

Does level D personal protective equipment guard against hazardous biologic agents during cardiopulmonary resuscitation?

OBJECTIVES

Our aim was to determine the usefulness of level D personal protective equipment (PPE) in safeguarding health care staff who perform cardiopulmonary resuscitation (CPR).

MATERIAL AND METHODS

Quasi-experimental, uncontrolled trial in 96 volunteers chosen randomly and stratified by sex, level of training, and professional category. The subjects were selected from a convenience sample of 164 nurses, physicians, and students of nursing and medicine (40 men [41.66%] and 56 women [58.33%]). The mean (SD) age was 31 (11) years. The Conconi test was used to determine heart rate (HR) at the anaerobic threshold on a cycle ergometer. That HR was then compared to each volunteer's maximum HR during performance of CPR while wearing PPE.

RESULTS

While the volunteers were performing CPR, 46.9% of them surpassed their maximum recommendable HR recorded during the cycle ergometer test.

CONCLUSION

We found that performing CPR while wearing level D PPE requires intense physical effort. Special situations should be taken into consideration when developing protocols for situations that require staff to wear PPE. Staff who must perform CPR under these conditions should be given specific training.

Planning to reduce 30-day adverse events after discharge of frail elderly patients with acute heart failure: design and rationale for the DEED FRAIL-AHF trial

OBJECTIVES

To demonstrate the efficacy of a system for comprehensive care transfer (Multilevel Guided Discharge Plan [MGDP]) for frail older patients diagnosed with acute heart failure (AHF) and to validate the results of MGDP implementation under real clinical conditions. The MGDP seeks to reduce the number of adverse outcomes within 30 days of emergency department (ED) discharge.

MATERIAL AND METHODS

We will enroll frail patients over the age of 70 years discharged home from the ED with a main diagnosis of AHF. The MGDP includes the following components: 1) a checklist of clinical recommendations and resource activations, 2) scheduling of an early follow-up visit, 3) transfer of information to the primary care doctor, and 4) written instructions for the patient. Phase 1 of the study will be a matched-pair cluster-randomized controlled trial. Ten EDs will be randomly assigned to the intervention group and 10 to the control group. Each group will enroll 480 patients, and the outcomes will be compared between groups. Phase 2 will be a quasi-experimental study of the intervention in 300 new patients enrolled by the same 20 EDs. The outcomes will be compared to those for each Phase-1 group. The main endpoint at 30 days will be a composite of 2 outcomes: revisits to an ED and/for hospitalization for AHF or cardiovascular death.

CONCLUSION

The study will assess the efficacy and feasibility of comprehensive MGDP transfer of care for frail older AHF patients discharged home.

Do bad habits bring a double constipation risk?

BACKGROUND/AIMS

Good dietary habits, fluid intake, and regular exercise are considered to ease defecation although very few cases of chronic constipation can be managed through these approaches alone. Good defecation habits are recommended to avoid chronic constipation; however, the literature regarding this remains scarce. In this paper, we aimed to assess the association of bad habits concerning defecation, such as postponing, reluctance, or avoiding defecation anywhere but at home, with chronic constipation.

MATERIALS AND METHODS

This was a cross-sectional observational study including subjects from a tertiary hospital taskforce. In total, 415 of 910 eligible subjects were randomly selected. A cluster of questionnaires easy to understand and fill out was distributed. The questionnaires included queries regarding demographic data; past medical history; the presence of constipation; and dietary, other lifestyle, and defecation habits. The Rome III criteria for chronic constipation were also recorded.

RESULTS

In total, 24.3% of the subjects considered themselves constipated, and 26.5% fulfilled the Rome III criteria for constipation. There were obvious differences in constipation prevalence by sex (men 5% vs. women 31%). Fiber-rich diet, fluid intake, and exercise habits were not related to constipation. Defecation habits significantly correlated with the presence or absence of constipation: regular schedule (OR 0.39; CI 95% 0.23-0.67), persistently postponing defecation (OR 1.94; CI 95% 1.13-3.34), or avoiding defecation anywhere but at home (OR 2.38; CI 95% 1.4-4.1).

CONCLUSION

Compared with dietary habits, behavioral aspects surrounding defecation are more related to chronic constipation. Our results indicate that the modification of these bad habits may be the first step in chronic constipation treatment.

[Medication reconciliation errors according to patient risk and type of physician prescriber identified by prescribing tool used]

OBJECTIVES

To study the frequency of medication reconciliation errors (MREs) in hospitalized patients and explore the profiles of patients at greater risk. To compare the rates of errors in prescriptions written by emergency physicians and ward physicians, who each used a different prescribing tool.

MATERIAL AND METHODS

Prospective cross-sectional study of a convenience sample of patients admitted to medical, geriatric, and oncology wards over a period of 6 months. A pharmacist undertook the medication reconciliation report, and data were analyzed for possible associations with risk factors or prescriber type (emergency vs ward physician).

RESULTS

A total of 148 patients were studied. Emergency physicians had prescribed for 68 (45.9%) and ward physicians for 80 (54.1%). A total of 303 MREs were detected; 113 (76.4%) patients had at least 1 error. No statistically significant differences were found between prescriber types. Factors that conferred risk for a medication error were use polypharmacy (odds ratio [OR], 3.4; 95% CI, 1.2-9.0; P=.016) and multiple chronic conditions in patients under the age of 80 years (OR, 3.9; 95% CI, 1.1-14.7; P=.039).

CONCLUSION

The incidence of MREs is high regardless of whether the prescriber is an emergency or ward physician. The patients who are most at risk are those taking several medications and those under the age of 80 years who have multiple chronic conditions.

[Communication of the Diagnosis of Down Syndrome: Mother's Stories]

The article studies the way in which health professionals communicate the diagnosis of Down syndrome to parents. For that the personal stories of the mothers collected in the answers given by them to the open questions of a questionnaire on ″communication of the diagnosis″ are analyzed. The results show the mothers' dissatisfaction with the information received during the prenatal and postnatal diagnosis of Down síndrome.

Incidence of and associated factors for bacterial colonization of intravenous catheters removed from dogs in response to clinical complications

BACKGROUND

Infection rate associated with intravenous (IV) catheter placement is emerging as an important issue in small animal veterinary medicine, mostly because of the economic costs associated with these infections. Identification of possible associated factors may provide useful information for the surveillance and prevention of such infections.

OBJECTIVES

To determine the incidence of positive bacterial cultures obtained from IV catheters used in dogs hospitalized for at least 48 hours and removed because of clinical complication. To identify the bacteria involved and factors associated with bacterial colonization.

ANIMALS

One-hundred eighty-two dogs that underwent IV catheterization from January 2015 to July 2015 at the Veterinary Teaching Hospital of Alfonso X el Sabio University of Madrid were enrolled in the study.

RESULTS

The bacterial colonization rate of all IV catheters removed in response to clinical complications was 39.6%, the cumulative proportion of catheters that remained in place at 24, 48, and 72 hours after placement was 89.5, 78, and 59.4%, respectively. Multivariable Cox proportional hazards regression indicated significant associations for staff who performed catheterization (junior, P = .002; student, P = .034) and use of steroidal anti-inflammatory drugs (P = .036). The most frequently isolated bacterium was Acinetobacter spp. (21.7%).

CONCLUSIONS AND CLINICAL IMPORTANCE

The bacterial colonization incidence related to IV catheter placement was slightly higher than the incidence described in other veterinary studies. Associated factors not previously described in veterinary medicine were found. The most frequently isolated organism was Acinetobacter spp., indicating its importance as an emerging pathogen in catheter colonization.

RECALAD. Patient care at National Health System Digestive Care Units - A pilot study, 2015

OBJECTIVES

To reach a situation diagnosis on the status of patient management at digestive care units (DCUs) in Spain.

MATERIAL AND METHODS

A cross-sectional descriptive study across DCUs in general acute care hospitals within the Spanish National Health System (data referred to 2015). The study variables were collected with a questionnaire including items on structure, services portfolio, activity, education, research, and good practice. Hospital discharge rates for digestive diseases were also assessed using the minimum basic data set (2005-2014).

RESULTS

Two hundred and nine hospitals invited, 55 responders (26.3%). Average discharges from hospital were 1,139 ± 653 per DCU/year, and 100 ± 66 per year per dedicated gastroenterologist. In 2014, admission rate to DCUs per 1,000 population and year was 280, with a mean stay of 7.4 days. The analysis of the MBDS for 2005-2014 reveals a progressive increase in the number of discharges (37% more in 2014 versus 2005), with a 28% decrease in hospital gross mortality rate (3.7% in 2014) and a slightly reduced (14%) mean stay (7.6 days in 2014). Considerable variability may be seen in structure, activity, and results indicators. Mortality and readmission rates, as well as mean stay, vary more than 100% amongst DCUs, and major dispersions also exist in frequentation and results amongst autonomous communities.

CONCLUSIONS

The RECALAD 2015 survey unveiled relevant aspects related to DCUs organization, structure, and management. The notable variability encountered likely reflects relevant differences in efficiency and productivity, and thus points out there is ample room for improvement.

Prevalence of anal incontinence in a working population within a healthcare environment

OBJECTIVES

Anal incontinence is a devastating affliction with several considerations that make it difficult to define in terms of epidemiology with good precision. The aim of the present work is to study the prevalence of an important disorder such as anal incontinence in a healthy working population within a sanitary environment.

MATERIAL AND METHODS

A cluster of easy understanding and filling inquiry forms are distributed to 910 apparently healthy individuals at our hospital. This questionnaires include filiation data, passed medical history, presence or not of Incontinence and other symptoms such as urgency. The Cleveland Clinic Incontinence Score is also registered.

RESULTS

Anal incontinence is present in a 21.2% of subjects when considered in any of it forms (flatus, liquid or solid faeces). A Clevleand Clinic Incontinence Score higher than 6 was obtained in a 7.3% of the sample and higher than 10 in 1.2%. No gender predominance has been identified. A slightly higher severity is recognised with increasing age. Obstetric and anal surgical background are the only related factors identified in the studied sample.

CONCLUSIONS

Faecal incontinence is a high prevalent affliction, even among apparently healthy population. Considering the aetiologic factors that have been established, prevention during obstetric and anal surgical procedures is absolutely mandatory.

Ocular Redness Measured with the Keratograph 5M in Patients Using Anti-Glaucoma Eye Drops

PURPOSE

To examine correlations between ocular redness measured with the new topographer Keratograph 5M and the use of topical anti-glaucoma medication.

METHODS

A total of 211 eyes of 211 patients with open-angle glaucoma or ocular hypertension on topical medication and 51 eyes of 51 healthy volunteers were recruited over 10 months. Outcome variables were keratograph redness scores (RS): overall, bulbar temporal (BT), bulbar nasal (BN), limbar temporal (LT), and limbar nasal (LN). In each subject, we also recorded the intraocular pressure-lowering eye drops used, daily doses and daily and cumulative preservative concentrations, fluorescein corneal staining score (OXFORD), lower tear meniscus height (Fourier-domain OCT), non-invasive tear film breakup time (Keratograph 5M), and ocular surface disease questionnaire index (OSDI).

RESULTS

Higher RS were recorded in the medication than control group (P < 0.01 all scores). Within the medication group, older patients returned greater RS (P < 0.05 all scores). Prostaglandin was a strong predictor of higher scores, except LN RS. A higher OSDI was associated with a higher LN RS (β = 0.007; P < 0.05), while the use of β-blockers was linked to a lower LN RS (β = -0.225; P < 0.05). The use of ≥3 daily eye drops with preservative gave rise to a higher BN RS and ≥3 daily eye drops to a higher LN RS (β = 0.366, P < 0.01; β = 0.296, P < 0.05, respectively).

CONCLUSION

Keratograph 5M can objectively detect the hyperaemia induced by glaucoma medication. The factors contributing to ocular redness were advanced age, more daily eye drops (nasal sectors), a higher OSDI, and prostaglandin as the medication used.

Attempted suicides attended by emergency services during the economic recession in Castile-La Mancha, Spain

OBJECTIVES

To investigate changes in attempted suicide rates in Castile-La Mancha between 2006 and 2015 and the correlation with sociodemographic and economic indicators.

MATERIAL AND METHODS

Study of attempted suicides attended by the emergency medical services of Castile-La Mancha between 2006 and 2015.We obtained records of the number of incidents and recorded sociodemographic and economic variables. Rates were standardized by direct reference to regional population figures, and change over time was studied by means of segmented Poisson regression models. The correlation with economic indicators was assessed with the Pearson correlation coefficient.

RESULTS

A total of 1308 attempted suicides were attended; 711 (55.8%) were made by women. The years 2007 and 2013 saw the highest numbers of attempts. The population-standardized suicide rates were 23% higher in women than in men, 10% higher in Toledo than in Albacete, 20% higher in 2007-2008 and 30% to 40% higher between 2012 and 2015 than before the crisis began. Rates were higher in age brackets in which employment is usual. Rates correlated most strongly with economic strain (difficulty making it to the end of the monthly pay cycle) (r=0.29, P<.01), risk of poverty/exclusion in the region (r=0.285, P<.01), and the unemployment rate in the region (r=0.265, P<.01).

CONCLUSION

. Suicide rates rose during the economic recession. There were variable correlations between socioeconomic indicators and attempted suicide rates.

[Impact of an emergency department short-stay unit on clinical management and quality of hospital care indicators]

OBJECTIVES

The primary aim was to study the impact that creating a short-stay unit (SSU) had on clinical management and quality of care indicators of a hospital overall and its conventional wards. The secondary aim was to establish values for those indicators and determine the level of satisfaction of patients admitted to the SSU.

MATERIAL AND METHODS

Quasi-experimental before-after study of the impact of establishing a SSU in a tertiary care teaching hospital. The first period (without the SSU) was in 2012, the second (with the SSU) was from 2013 through 2015. To meet the first objective we selected cases in 2012 in which patients were hospitalized for problems related to the 5 diagnosis-related groups most often admitted to the SSU in the second period. To meet the second objective, we studied all patients admitted to the SSU in the second period Data related to quality of care and clinical management were analyzed retrospectively. and asked them to complete a questionnaire on patient satisfaction.

RESULTS

A total of 76 241 admissions were included: 19 090 in the first period and 57 151 in the second (2705 admissions were to the SSU). The mean hospital stay decreased in the second period (incidence rate ratio [IRR], 0.93; 95% CI, 0.91-0.95); the mean stay also decreased on medical wards (IRR, 0.94; 95% CI, 0.92-0.96) with no impact on adverse outcomes. The mean stay in the SSU was under 3 days in spite of an increase in the weighted mean (IRR,1.08; 95% CI, 1.05-1.11). A total of 320 questionnaires were received (11.8% response rate); all aspects were assessed very highly.

CONCLUSION

Our experience suggests that opening a SSU could improve clinical management and quality of care indicators for a hospital overall and for its conventional wards in the context of the GRDs that most frequently lead to admissions.

The RECALCAR Project. Healthcare in the Cardiology Units of the Spanish National Health System, 2011 to 2014

The RECALCAR project (Spanish acronym for Resources and Quality in Cardiology Units) uses 2 data sources: a survey of cardiology units and an analysis of the Minimum Basic Data set of all hospital discharges of the Spanish National Health System. From 2011 to 2014, there was marked stability in all indicators of the availability, utilization, and productivity of cardiology units. There was significant variability between units and between the health services of the autonomous communities. There was poor implementation of process management (only 14% of the units) and scarce development of health care networks (17%). Structured cardiology units tended to have better results, in terms of both quality and efficiency. No significant differences were found between the different types of unit in the mean length of stay (5.5±1.1 days) or the ratio between successive and first consultations (2:1). The mean discharge rate was 5/1000 inhabitants/y and the mean rate of initial consultations was 16±4/1000 inhabitants/y. No duty or on-call cardiologist was available in 30% of cardiology units with 24 or more beds; of these, no critical care beds were available in 45%. Our findings support the recommendation to regionalize cardiology care and to promote the development of cardiology unit networks.

[Circadian variation in the effectiveness of reperfusion therapy in ST-segment elevation myocardial infarction treated with primary angioplasty and circadian associations with prognosis]

OBJECTIVES

To explore circadian variation in the effectiveness of percutaneous transluminal coronary angioplasty (PTCA) to treat ST-elevation myocardial infarction (STEMI) To explore the effects of circardian variation on infarct extension and in-hospital complications.

MATERIAL AND METHODS

Observational retrospective cohort study including patients with PTCA-treated STEMI in a tertiary care university hospital between March 2003 and August 2009. The independent variable of interest was the time of onset of STEMI symptoms, grouped in 6-hour time frames. The main outcome variable was PTCA effectiveness. Secondary outcome variables were infarct extension and the presence of in-hospital complications.

RESULTS

A total of 522 patients records were studied. The mean (SD) age was 62.3 (13.6) years and 404 (77.4%) were men. The largest proportion of PTCA-treated STEMI cases first experienced symptoms between 6 AM and 12 PM (201 cases, 38.5%) (P<.001). PTCA was ineffective in 122 (23.4%). The 6 AM to 12 PM time frame was an independent predictor of PTCA ineffectiveness (odds ratio, 1.79; 95% CI, 1.09-2.94; P=.012). Onset in this interval was also associated with infarct extension but not with in-hospital complications.

CONCLUSION

A time of onset of STEMI between 6 AM and 12 PM predicts the ineffectiveness of PTCA and greater infarct extension but not in-hospital complications.

Development of a Telemetric System for Postoperative Follow-up of Vascular Surgery Procedures: In Vitro Model

Background

Because of the unique electromagnetic characteristics of the magnetoelastic microwire, the changes in the pressure of a fluid will provoke a variation of the mechanical pressure on the sensor, which will cause a variation of its magnetization that will be detectable wirelessly. Thus, a wireless system can be developed for following up vascular surgery procedures.

Methods and Results

The sensor consists of a magnetoelastic microwire ring, which was integrated into an in vitro model with pulsatile flow. Different degrees of stenosis were simulated in different locations both in bovine artery as well as in a polytetrafluoroethylene anastomosis. A Fourier analysis of the registered signals and a statistical analysis using Pearson test and receiver operating characteristic (ROC) curves were made. A Pearson index of 0.945 (P<0.001) was obtained between the invasive pressure of the fluid and the power of the signal transmitted by the sensor in bovine artery. The sensor obtained very good ROC curves upon analyzing the signals registered, both in the case of preanastomotic stenosis (area under the curve [AUC], 0.98; 95% CI, 0.97–1.00), of anastomosis (AUC, 0.93; 95% CI, 0.86–0.99), as well as distal (AUC, 0.88; 95% CI, 0.79–0.98), compared to the control group.

Conclusions

The magnetoelastic microwire has shown that it is capable of detecting, locating, and quantifying the degree of stenosis in bovine artery, as well as in a latero‐terminal anastomosis, with a high statistical potency. For the first time, a wireless in vitro sensor has been developed for the postoperative follow‐up of vascular surgery procedures.

[Clinical profile and 90-day mortality in centenarian patients attended in emergency departments]

OBJECTIVES

To determine the clinical profile and to develop a model to predict 90-day mortality in centenarian patients attended in emergency departments (ED).

METHODOLOGY

This was an observational, retrospective, multicentre cohort study including patients >99years attended in 5 ED in the Community of Madrid from January to December 2012. Demographic variables were recorded, as well as, comorbidities, cognitive, functional, social basal status, geriatric syndromes, acute episode, and hospital and social resources use, and 90-day mortality.

RESULTS

The study included 209patients aged 101years (SD 1.7) of whom 161 (77.0%) were female. Sixty four (32.5%) had severe comorbidity (Charlson index≥3), 101 (49.8%) on multiple medication, 100 (52.6%) had cognitive impairment, 82 (42.3%) had severe functional dependence, 85 (40.7%) were institutionalised, and 190 (94.5%) had a geriatric syndrome. Dyspnoea (26.8%), followed by falls (12.4%) were the most common causes of attendance. One hundred and eighteen (56.5%) were admitted, and 58 out of 174 (33.3%) died in the first 90days. The model to predict 90-day overall mortality included male sex (OR 2.42 95% CI=0.97-6.04; P=.059), emergency care in the previous 3months (OR 4.08 95% CI=1.26-13.16; P=.019) and the hospitalization by index event (OR 8.63 95% CI=3.25-22.9; P<.001) and this model had an area under ROC curve of 0.776 (95% CI=0.70-0.85; P<.001).

CONCLUSIONS

Centenarian patients attended in ED had a significant frailty and one in three cases died in the first 90days after being attended, and this was associated with male sex, emergency care in the previous 3months, and hospitalisation.

[Demand for emergency department care for vertebral fractures treated with transdermal buprenorphine vs. other analgesics]

OBJECTIVES

To compare the results of emergency department management of spinal pain from vertebral fractures (in terms of revisits, adverse effects at 90 days, or need for hospitalization because of poor pain control at 6 months) in patients treated with transdermal buprenorphine or another analgesic.

MATERIAL AND METHODS

Retrospective observational study of cohorts in an emergency department database compiled prospectively over a period of 18 months. We included all patients over the age of 60 with a radiologic diagnosis of vertebral fracture or compression causing pain for more than 3 months. Records were stratified according to the World Health Organization (WHO) analgesic scale, which was used when the patients were treated. Variables related to effectiveness were revisits at 1 month, time between visits in days, and the need for hospitalization.

RESULTS

A total of 180 patients were included; 39 were treated with drugs on the first step of the WHO's analgesic ladder, 74 with second-step drugs (mainly tramadol), and 67 with transdermal buprenorphine, a third-step drug. Half the patients treated with buprenorphine had revisited at 50 days or later (interquartile range [IQR, 41-60 days); half those treated with first-step analgesics had revisited by 19 days IQR, 10-37 days), and half those on second-step drugs had revisited by 28 days (IQR, 21-53 days) (P<.001). After adjustment for other variables, patients treated with first-step drugs revisited 4.19-fold more (95% CI, 2.57-6.80; P<.001) and those treated with second-step drugs revisited 1.91-fold more (95% CI, 1.22-2.99; P=.005) more than patients treated with transdermal buprenorphine.

CONCLUSION

Transdermal buprenorphine used to manage spinal pain seems to significantly reduce the need for revisits in comparison with treatments with first- or second-step analgesics.
