Professionals' Perception of a Strategy to Avoid Interruptions During Medication Handling.

INTRODUCTION: The use of vests for handling medication (prescription, preparation, and dispensing) in the emergency department is a strategy designed to increase patient safety by reducing interruptions and, consequently, medication errors. In this study, we aim to assess how professionals perceive the use of vests in a pediatric emergency department of a tertiary hospital. MATERIAL AND METHODS: A cross-sectional survey was conducted among pediatric emergency physicians and nurses in October and November 2019. We analyzed the results of a 19-item survey on the perception of vests as a tool for reducing interruptions and medication errors. RESULTS: In this study, 91 surveys were delivered and 89 (97.8%) were completed. One hundred percent of the professionals were aware of the vests. Nurses reported the following reasons for not using the vest: high workload (25%) and preparation of nebulized and oral medications (25%). One hundred percent of doctors asked for the vest because of forgetfulness. Thirty-five physicians (81.4%) and 17 nurses (85.0%) said that wearing the vest, they were rarely or never interrupted. Eighty-two respondents (93.2%) agreed that vests are an effective strategy for minimizing medication errors. CONCLUSIONS: Although medical professionals consider vests to be a useful strategy to prevent interruptions and reduce medication errors, adherence to the protocol is low, so a promotion strategy is needed to encourage professionals to use the vests.

Parent Perception of Child Safety following Admission to a Neonatal Unit.

OBJECTIVE: Parent partnership is a key aspect of neonatal hospital care. However, there is a lack of information regarding parents' perception of neonatal safety. This study explores parents' opinions on safety during their child's hospitalization to identify points for improvement. STUDY DESIGN: We used a questionnaire, validated by the Spanish National Healthcare Authorities, on perception of safety with respect to hospital health care. RESULTS: Thirty-seven parents of 20 newborns treated in the neonatal intensive care unit (NICU) and 139 parents of newborns in intermediate care (IC) participated in this study. With regard to overall perception of safety, more than 96% of parents felt "very safe" or "fairly safe." In the NICU, an area for improvement detected was to ask parents more often their opinion about the care or treatment provided to their child. In IC, three points for improvement were identified from the group of parents whose child was admitted directly to IC: the consistency of the information received, the request for consent for procedures, and the request for an opinion on their child's care and treatment. Only four parents reported that their child suffered an incident. Regarding incident management, parents were not completely satisfied with the information they received. CONCLUSION: To the best of our knowledge, this is the first study of parent perception of patient safety in a neonatal unit using a validated questionnaire. Our findings suggest that parents can provide valuable information on neonatal safety, which can then be used to identify areas for improvement. KEY POINTS: · There is a lack of information regarding parents' perception of neonatal safety.. · This study explores parent's opinion about safety of their child during the hospitalization.. · Our findings suggest that parents can provide valuable information to identify improvement areas..

Impact of risk mapping as a strategy for monitoring and improving patient safety in paediatric emergency care.

OBJECTIVE: To design a risk map (RM) as a tool for identifying and managing risks in the paediatric emergency department and to assess the impact of the improvement actions developed based on the identified risks in terms of the level of risk to patient safety. METHODOLOGY: A multidisciplinary working group reviewed the entire care process by applying the Failure Mode and Effects Analysis (FMEA) tool. Project phases: (1) RM 2017 and planning of improvement actions; (2) Development and implementation of improvement actions; (3) RM 2019; (4) Analysis: evolution of the RM and impact of improvement actions. RESULTS: A total of 106 failure modes (FMs) were identified in the 2017 RM (54.7% high- or very high risk). We applied prioritization criteria to select the improvement actions to plan. Nineteen improvement actions were planned, with assigned responsible parties and deadlines, to address 46 priority FMs. One hundred percent were implemented. In the 2019 RM, we identified 110 FMs (48.2% high risk) and found an overall reduction of the risk level of 20%. Analysing the 46 priority FMs that had been addressed by the 19 planned improvement actions, we found that 60% had changed from high to medium risk level and that the risk level had decreased, both overall (-27.8%) and by process. CONCLUSION: The FMEA is a useful tool to identify risks, analyse the impact of improvement strategies and monitor the risk level of a complex clinical care department. The improvement actions developed succeeded in reducing the level of risk in the processes in our unit, improving patient safety.

Briefings: A Tool to Improve Safety Culture in a Pediatric Emergency Room.

BACKGROUND: Safety briefings are short, informative meetings intended to integrate a culture of patient safety into daily clinical practice, which contributes to identifying risks and improving quality. The objective of this study is to present safety briefings as a method for discovering and addressing safety events in a pediatric emergency room, describe how professionals perceive them, and characterize the classification and evolution of the incidents identified. METHODS: This observational, descriptive, analytical study was performed in the pediatric emergency department of a tertiary hospital in 2018-2019. The incidents reported during the briefings were counted, classified, and analyzed. Results of a 10-item survey on the usefulness of the briefings in identifying and managing risks are described. RESULTS: A total of 498 briefings were analyzed, in which 1,180 incidents were reported (1 incident/96 emergency cases; 2.4 incidents/meeting). The category with the most incidents was Communication. The number of incidents fell by 24.4% between 2018 and 2019 (p < 0.01), mostly in the Identification (47.8%) and Communication (33.8%) categories. Seventy-seven surveys were analyzed. In 97.4% of the analyzed surveys, the person surveyed considered the briefings to be useful in improving patient safety; 90.9% considered notification via briefings to be more convenient than through electronic means. In 35.1%, the person surveyed was not satisfied with the information received on incident management. CONCLUSION: Patient safety briefings are perceived as a useful tool to report incidents, and incidents related to communication occur most frequently. Safety briefings are perceived as useful for improving patient safety in pediatric emergency rooms, and this method of notification is considered more convenient than other methods.

Metabolic bone disease in patients diagnosed with inflammatory bowel disease from Spain.

BACKGROUND: The objective of this study was to analyse the prevalence of metabolic bone disease (MBD) in a cohort of Southern European patients with inflammatory bowel disease (IBD) and to identify associated risk factors in this population. METHODS: We conducted a retrospective, both cross-sectional and longitudinal study of MBD, assessed by dual energy X-ray absorptiometry (DXA), among patients diagnosed with IBD and previously recognized risk factors for this complication from two referral Spanish institutions. RESULTS: A total of 612 patients (58.6% diagnosed with Crohn's disease) were included. Mean (SD) age was 44.9 (14.7) years; 71.7% of patients received at least one tapered dosage of corticosteroids before first DXA. MBD and osteoporosis were diagnosed in 66.4% and 21.4% of patients, respectively. At baseline, male gender, menopause and ulcerative colitis were found as independent risks factors for osteoporosis, whereas age, more than three IBD-related hospitalizations and previous steroid treatment were found as independent risks factors for MBD. A total of 261 patients had at least a second DXA and were included in the longitudinal study; median follow up was 56.4 months. Logistic regression model identified menopause, ulcerative colitis and baseline lumbar DXA T-score value, but not steroid treatment, as risk factors for worsening ⩾1 SD in follow-up DXA T-score. According to guidelines, all patients under treatment with corticosteroids received calcium and vitamin D supplements. CONCLUSION: MBD is a frequent complication in south-European IBD patients. Routine evaluation of bone density when risk factors are present, as well as calcium plus D vitamin prophylaxis in patients under corticosteroid treatment should be recommended.

Multidisciplinary strategy to reduce errors with the use of medical gases.

OBJECTIVE: Lack of awareness of the risks associated with the use of medical  gases amongst health professionals and health organizations is concerning. The  objective of this study is to redefine the use process of medical gases in a  hospital setting. METHOD: A sentinel event took place in a clinical unit, the incorrect administration of a medical gas to an inpatient. A multidisciplinary  causeroot analysis of the sentinel event was carried out. Different improvement points were identified for each error detected and so we defined a  good strategy to ensure the safe use of these drugs. RESULTS: 9 errors were identified and the following improvement actions were  defined: storage (gases of clinical use were separated from those of industrial  use and proper identification signs were placed), prescription (6 protocols were  included in the hospital´s Computerized Physician Order Entry software),  validation (pharmacist validation of the prescription to ensure appropriate use of  these), dispensation (a new protocol for medical gases dispensation and  transportation was designed and implemented) and administration (information  on the pressure gauges used for each type of gas was collected and reviewed).  72 Signs with recommendations for medical gases identification and  administration were placed in all the clinical units. Specific training on the safe  use of medical gases and general safety training was imparted. CONCLUSIONS: The implementation of a process that integrates all phases of use  of medical gases and applies to all professionals involved is presented here as a  strategy to increase safety in the use of these medicines.

Objetivo: Existe una falta de concienciación sobre los riesgos asociados al uso  de los gases medicinales tanto por parte de los profesionales como por parte de  las organizaciones sanitarias, que no han definido estrategias que garanticen la  seguridad en su utilización. Nuestro objetivo fue redefinir el circuito de  utilización de los gases medicinales en el ámbito hospitalario.Método: En una unidad de hospitalización tuvo lugar un evento centinela, la  administración incorrecta de un gas medicinal a un paciente ingresado. Un  equipo multidisciplinar realizó el análisis causa-raíz del evento. Se propusieron áreas de mejora encaminadas a actuar sobre los errores detectados y así definir un programa que garantizara la seguridad en el uso de los gases medicinales.Resultados: Se identificaron nueve errores y se definieron acciones de mejora  en: almacenamiento (separación e identificación de los gases de uso clínico y de  los de uso industrial); prescripción (inclusión de seis protocolos en el programa  de prescripción electrónica); validación (revisión de la prescripción de los gases  medicinales por un farmacéutico); dispensación (implantación de un protocolo  de traslados), y administración (información sobre los manómetros utilizados  para cada tipo de gas). Además, se impartió formación relativa al uso de los  gases medicinales. Se colocaron 72 pósteres en las unidades clínicas con  recomendaciones para su uso seguro. Conclusiones: La implantación de un circuito que integra todas las fases de  utilización de los gases medicinales e implica a todos los profesionales involucrados se presenta como la estrategia dirigida a aumentar la seguridad en  la utilización de estos medicamentos.

[Detection of adverse events using trigger tools in 2hospital units in Spain]. / Detección de eventos adversos mediante trigger tools en 2unidades de hospitalización de un hospital terciario en España.

INTRODUCTION: Adverse events (AE) related to health care are frequent due to the nature of this activity, and for this reason, it is necessary to develop methods to detect them and prevent their recurrence. One of these methods uses what are called trigger tools, which are markers that allow AE to be identified retrospectively for subsequent analysis. OBJECTIVES: To evaluate the usefulness of a trigger tools system to detect AE related to patient safety in Internal Medicine and General Surgery units of a tertiary referral hospital. As secondary objectives, measurements were made of the rate of AE, its prevalence in admissions, as well as a description of the different types of AE, and to evaluate the time spent using this tool. MATERIAL AND METHODS: A retrospective descriptive study of patients admitted to the units of Internal Medicine and General Surgery and discharged during 2016. Inclusion criteria were hospital stay over 24h and the presence of a complete clinical record of the studied acute episode. Patients admitted to short-stay units were excluded. A verification questionnaire was designed to registry key study variables and associated AE. RESULTS: The study included 118 patients from Internal Medicine and 115 from General Surgery. The presence of at least one trigger was detected in 86 (72.9%) Internal Medicine and 56 (48.7%) General Surgery patients. Of these, 13 (15.1%) were associated with the presence of an AE in Internal Medicine and 34 (60.7%) in General Surgery. The trigger tool system failed to detect 7 AE, 4 of them in Internal Medicine. The median of triggers identified in each patient was 1.5 (IQR p25-p75: 1-2.5) in Internal Medicine and 2 (IQR p25-p75: 1-4) in General Surgery. In total, 262 positive triggers were detected, of which 157 corresponded to Internal Medicine, most of them related to early emergency re-admission after discharge. Most of the identified AEs required re-hospitalisation or extending the length of stay. CONCLUSIONS: Trigger tools systems are useful for the detection and characterisation of AE, which helps to analyse and implement improvement measures.

[Improving patient safety: Usefulness of safety checklists in a neonatal unit]. / Mejorando la seguridad del paciente: utilidad de las listas de verificación de seguridad en una unidad neonatal.

INTRODUCTION: Due to the complexity and characteristics of their patients, neonatal units are risk areas for the development of adverse events (AE). For this reason, there is a need to introduce and implement some tools and strategies that will help to improve the safety of the neonatal patient. Safety check-lists have shown to be a useful tool in other health areas but they are not sufficiently developed in Neonatal Units. MATERIAL AND METHODS: A quasi-experimental prospective study was conducted on the design and implementation of the use of a checklist and evaluation of its usefulness for detecting incidents. The satisfaction of the health professionals on using the checklist tool was also assessed. RESULTS: The compliance rate in the neonatal intensive care unit (NICU) was 56.5%, with 4.03 incidents per patient being detected. One incident was detected for every 5.3 checklists used. The most frequent detected incidents were those related to medication, followed by inadequate alarm thresholds, adjustments of the monitors, and medication pumps. The large majority (75%) of the NICU health professionals considered the checklist useful or very useful, and 68.75% considered that its use had managed to avoid an AE. The overall satisfaction was 83.33% for the professionals with less than 5 years working experience, and 44.4% of the professionals with more than 5 years of experience were pleased or very pleased. CONCLUSION: The checklists have shown to be a useful tool for the detection of incidents, especially in NICU, with a positive assessment from the health professionals of the unit.

Economic impact of clinical variability in preoperative testing for major outpatient surgery. / Impacto económico de la variabilidad clínica en la petición de pruebas preoperatorias en cirugía mayor ambulatoria.

BACKGROUND: With the purpose of decreasing the existing variability in the criteria of preoperative evaluation and facilitating the clinical decision-making process, our hospital has a protocol of preoperative tests to use with ASA I and ASA II patients. The aim of the study was to calculate the economic impact caused by clinicians' non-adherence to the protocol for the anaesthesiological evaluation of ASA 1 and ASA II patients. METHODS: A retrospective study of costs with a random sample of 353 patients that were seen in the consultation for Anesthesiology over a period of one year. Aspects related to the costs, patient's profiles and specialties were analysed, according to the degree of fulfillment of the protocol. RESULTS: The lack of adherence to the the protocol was 70%. 130 chest X-rays and 218 ECG were performed without indication. This generated an excess costs of 34 € per patient. Taking into account the expenses of both tests and the attended population undergoing ambulatory surgery during the one-year period, an excess spending for the hospital of between 69.164 € and 83.312 € was estimated. CONCLUSIONS: Clinical variability should be reduced and the creation of synergies between the different departments should be enhanced in order to adjust the request for unnecessary complementary tests to decrease health care and to improve the quality of patient care.

Quality of life of institutionalized older adults by dementia severity.

BACKGROUND: The goal of the study was to analyze the factors associated with quality of life (QoL) in institutionalized older adults with dementia, based on self and proxy ratings, and if these characteristics differ by dementia severity. METHODS: Cross-sectional study of 525 people with dementia (PwD) and their caregivers (professional or family caregivers). Two different QoL questionnaires, leading to three measures, were used: QoL in Alzheimer's disease scale (QOL-AD), self and proxy-rated, and QoL in late-stage dementia scale (QUALID), proxy-rated. Multivariate linear regression models were tested for each QoL measure and for mild/moderate and severe stages of dementia. RESULTS: Multiple regression analyses showed a significant association between the three QoL measures and depression. Functional ability was significantly associated with QoL when assessed by proxy. Other factors such as education level, leisure activities and frequency of visits were significantly related with QOL-AD by proxy. The associated factors that differed by dementia severity were education level for moderate dementia, and frequency of visits and who answered the questionnaire (professional vs. family member) for severe dementia. CONCLUSIONS: QoL was consistently associated with depressive symptoms independently of the measures as well as functional ability and social leisure activities when the QoL questionnaire was rated by proxy. Treating depressive symptoms, increasing social activities and maintaining the functional ability may decrease the deterioration of QoL in institutionalized older adults with dementia.

Cardiometabolic Risk Profiles in Patients With Impaired Fasting Glucose and/or Hemoglobin A1c 5.7% to 6.4%: Evidence for a Gradient According to Diagnostic Criteria: The PREDAPS Study.

It has been suggested that the early detection of individuals with prediabetes can help prevent cardiovascular diseases. The purpose of the current study was to examine the cardiometabolic risk profile in patients with prediabetes according to fasting plasma glucose (FPG) and/or hemoglobin A1c (HbA1c) criteria.Cross-sectional analysis from the 2022 patients in the Cohort study in Primary Health Care on the Evolution of Patients with Prediabetes (PREDAPS Study) was developed. Four glycemic status groups were defined based on American Diabetes Association criteria. Information about cardiovascular risk factors-body mass index, waist circumference, blood pressure, cholesterol, triglycerides, uric acid, gamma-glutamyltransferase, glomerular filtration-and metabolic syndrome components were analyzed. Mean values of clinical and biochemical characteristics and frequencies of metabolic syndrome were estimated adjusting by age, sex, educational level, and family history of diabetes.A linear trend (P < 0.001) was observed in most of the cardiovascular risk factors and in all components of metabolic syndrome. Normoglycemic individuals had the best values, individuals with both criteria of prediabetes had the worst, and individuals with only one-HbA1c or FPG-criterion had an intermediate position. Metabolic syndrome was present in 15.0% (95% confidence interval: 12.6-17.4), 59.5% (54.0-64.9), 62.0% (56.0-68.0), and 76.2% (72.8-79.6) of individuals classified in normoglycemia, isolated HbA1c, isolated FPG, and both criteria groups, respectively.In conclusion, individuals with prediabetes, especially those with both criteria, have worse cardiometabolic risk profile than normoglycemic individuals. These results suggest the need to use both criteria in the clinical practice to identify those individuals with the highest cardiovascular risk, in order to offer them special attention with intensive lifestyle intervention programs.

The potential usefulness of human leukocyte antigen typing for celiac disease screening: A systematic review and meta-analysis.

BACKGROUND AND AIM: The presence of specific human leukocyte antigen-DQ2 and DQ8 seems to be necessary for celiac disease development, but the real contribution of its typing for screening is still uncertain. We aim to conduct a systematic review and meta-analysis of the diagnostic performance of human leukocyte antigen typing tests for celiac disease screening. METHODS: Systematic review of published studies assessing accuracy of human leukocyte antigen DQ2 and DQ8 typing for the detection of celiac disease were selected. MEDLINE and EMBASE were searched from 1st January 2004 until 31st December 2013. Two independent researchers carried out selection and classification of studies, data extraction and analysis. Meta-analysis combining sensitivities, specificities and likelihood ratios of HLA-DQ2 and DQ8 for the diagnosis of celiac disease were carried out. RESULTS: 6 studies including 1303 individuals were finally evaluated. Pooled sensitivity was 98% (95% confidence interval: 97-99). Overall specificity was 45% (95% confidence interval: 41-48). Regarding specificity, studies were heterogeneous and a subgroup analysis was done according to the type of population included. Overall negative likelihood ratio was 0.05 (0.03-0.09). CONCLUSIONS: Due to its great sensitivity and low negative likelihood ratio, human leukocyte antigen-DQ2/DQ8 typing would be an appropriate test for ruling out celiac disease in the general population suffering related symptoms, and even more in at risk population.

Lipid Profile in Inflammatory Bowel Disease Patients on Anti-TNFα Therapy.

BACKGROUND: Previous studies analyzing lipid profile in small cohorts of patients with rheumatic and inflammatory bowel diseases (IBD) treated with TNFα blockers showed conflicting results. We aim to evaluate the effect of anti-TNFα monoclonal antibodies, infliximab and adalimumab, on lipid profile in IBD patients followed up to 3 years. METHODS: Clinical charts of 128 consecutive IBD patients, who received at least three doses of infliximab or two doses of adalimumab, and with a clinical follow-up of at least 1 year, were retrospectively reviewed. Lipid profiles (total, HDL and LDL cholesterol, and triglycerides) before beginning the treatment and after 1 and 3 years of follow-up were collected. Multiple linear regression analysis was performed considering total cholesterol difference at basal time, 1 and 3 years as a dependent variable. RESULTS: There was not a statistically significant difference between pre- and post-treatment lipid profiles. However, the subgroup with normal-range total cholesterol level before anti-TNFα treatment (n = 82) showed a significant increase in total cholesterol after 1 and 3 years, and a significant increase in LDL cholesterol after 3 years. The subgroup with basal normal-range triglycerides showed a significant increase after 1 and 3 years of follow-up. Atherogenic index resulted significantly increased after 3 years of anti-TNFα treatment. Multivariate analysis showed no influence of age, gender, type of IBD, body mass index, or the presence of two or more cardiovascular risk factors. CONCLUSIONS: No significant changes in lipid profile of IBD patients on anti-TNFα therapy were observed after 1 and 3 years of treatment.

Modifiable risk factors associated with prediabetes in men and women: a cross-sectional analysis of the cohort study in primary health care on the evolution of patients with prediabetes (PREDAPS-Study).

BACKGROUND: Prediabetes is a high-risk state for diabetes development, but little is known about the factors associated with this state. The aim of the study was to identify modifiable risk factors associated with the presence of prediabetes in men and women. METHODS: Cohort Study in Primary Health Care on the Evolution of Patients with Prediabetes (PREDAPS-Study) is a prospective study on a cohort of 1184 subjects with prediabetes and another cohort of 838 subjects without glucose metabolism disorders. It is being conducted by 125 general practitioners in Spain. Data for this analysis were collected during the baseline stage in 2012. The modifiable risk factors included were: smoking habit, alcohol consumption, low physical activity, inadequate diet, hypertension, dyslipidemia, and obesity. To assess independent association between each factor and prediabetes, odds ratios (ORs) were estimated using logistic regression models. RESULTS: Abdominal obesity, low plasma levels of high-density lipoprotein cholesterol (HDL-cholesterol), and hypertension were independently associated with the presence of prediabetes in both men and women. After adjusting for all factors, the respective ORs (95% Confidence Intervals) were 1.98 (1.41-2.79), 1.88 (1.23-2.88) and 1.86 (1.39-2.51) for men, and 1.89 (1.36-2.62), 1.58 (1.12-2.23) and 1.44 (1.07-1.92) for women. Also, general obesity was a risk factor in both sexes but did not reach statistical significance among men, after adjusting for all factors. Risky alcohol consumption was a risk factor for prediabetes in men, OR 1.49 (1.00-2.24). CONCLUSIONS: Obesity, low HDL-cholesterol levels, and hypertension were modifiable risk factors independently related to the presence of prediabetes in both sexes. The magnitudes of the associations were stronger for men than women. Abdominal obesity in both men and women displayed the strongest association with prediabetes. The findings suggest that there are some differences between men and women, which should be taken into account when implementing specific recommendations to prevent or delay the onset of diabetes in adult population.

Safety and Efficacy of Anti-TNFα Treatment in Crohn's Disease Patients with Abdominal Abscesses.

BACKGROUND/AIMS: It is estimated that up to 30% of CD patients develop abdominal abscesses; the management of active luminal CD in such patients represents a clinical challenge. The aim of this study is to assess the safety of biologics in patients with Crohn's disease and abdominal abscesses treated with percutaneous drainage and/or broad-spectrum antibiotics. METHODOLOGY: We performed a retrospective review of the clinical charts of consecutive Crohn's disease patients with abdominal abscesses treated with anti-TNFα therapy attended in our institution. RESULTS: 12 patients were finally included in the study. All were treated with broad-spectrum antibiotic and biological therapy (anti-TNF); indication of anti-TNFα therapy was moderate to severe activity of CD in all of them. Percutaneous drainage of the abscess was performed in 7 of the 12 patients. No complications were observed during a mean follow-up of 37,8 (16-71) months, including abscess volume increase, enterocutaneous fistula, soft tissue infections, bacteraemia, or need for emergency surgery. CONCLUSIONS: In addition to conventional treatment, the use of anti-TNFα therapy in Crohn's disease patients with abdominal abscesses seems to be safe. Usefulness of this approach has to be validated in larger cohorts.

Change and predictors of quality of life in institutionalized older adults with dementia.

PURPOSE: This study aims to assess the change in and predictive factors of the quality of life (QoL) of institutionalized older adults with dementia over a 20-month period. METHODS: Information was used from a follow-up study conducted over an average period of 19.61 ± 1.93 months on a sample of 274 institutionalized older adults aged 60 or over, diagnosed with dementia. Two linear regression models were built to predict change in the EQ-5D index and the quality of life in Alzheimer's disease (QOL-AD) scale, taking as independent variables: sociodemographic characteristics and measures of functional ability (Barthel Index), depression in dementia (Cornell Scale), number of chronic health problems, cognitive level (MEC, the Spanish Mini-Mental State Examination) and severity of dementia (Clinical Dementia Rating) at baseline. RESULTS: The majority of the participants were women (81.75 %) with an average age of 84.70 ± 6.51 years, single (78.15 %), with severe dementia and moderate functional dependence. There was a significant decrease on the EQ-5D, EQ-VAS and QOL-AD between baseline and follow-up scores. The main predictors of QoL of the institutionalized older adults with dementia were the number of chronic problems and baseline scores of the QoL measures. CONCLUSIONS: A significant decrease in the QoL of institutionalized older adults was observed over a 20-month period. Results suggest that interventions aimed at reducing the number of chronic medical conditions may have a beneficial effect on older adults' QoL.

EQ-5D rated by proxy in institutionalized older adults with dementia: psychometric pros and cons.

AIM: Measurement of health-related quality of life in people with dementia is a challenge, because of their special characteristics and the difficulties that this term entails itself. The present study aimed at assessing the psychometric properties of the EQ-5D rated by a familiar or a professional caregiver of institutionalized older adults with dementia. METHODS: We analyzed the EQ-5D psychometric properties from 525 questionnaires rated by proxy, in a sample of institutionalized older adults with dementia. RESULTS: The mean EQ-5D index score was 0.11 ± 0.38, and 51.54 ± 21.47 for the visual analog scale. The intraclass correlation coefficient was 0.72. Regarding internal consistency, Cronbach's alpha was 0.64, and the item-total correlation ranged from 0.33 to 0.53. Exploratory factor analysis identified a functional and a subjective factor, accounting for 67.35% of the variance. Convergent validity of EQ-5D with Quality of Life Alzheimer's Disease by proxy and Quality of Life in Late-stage Dementia scales was satisfactory (r = 0.36-0.58). The EQ-5D showed appropriate discriminative validity among patients grouped into several categories. Multiple linear regression models, using EQ-index and visual analog scale as dependent variables, identified dependence level, proxy characteristics, leisure and comorbidity as determinants of quality of life. CONCLUSIONS: Despite some limitations in the more subjective dimensions, the proxy-rated EQ-5D showed satisfactory psychometric properties in the present study, suggesting that it is a valid and alternative instrument to assess quality of life in institutionalized older people with dementia.

[Cohort Study in Primary Health Care on the Evolution of Patients with Prediabetes (PREDAPS): basis and methodology].

The PREDAPS study aims to determine the risk of developing diabetes and the risk of vascular complications in patients with prediabetes and identify factors associated with those risks. It is a prospective observational study of a cohort of 1184 subjects with prediabetes and another cohort of 838 subjects with no alterations in glucose metabolism. The data at baseline were obtained from patients attending primary care centers in Spain throughout 2012. Subjects with prediabetes were classified into three groups: those who had only altered the fasting blood glucose levels -between 100 and 125mg/dl-, those who had only altered the HbA1c level -between 5.7 and 6.4% - and those who had altered both parameters. Information on sociodemographic characteristics, personal and family history, lifestyle and drug therapy was obtained from medical records and the interview with the doctor in the consultation. It was also performed a physical examination to determine weight, height, waist circumference and blood pressure were performed and blood and urine analysis. The PREDAPS study may help to reduce uncertainty in individual prevention strategies in subjects with prediabetes. Annual monitoring of patients recruited for five years will enable to know the risk of developing diabetes type 2 and the risk of macro-and microvascular complications in the three groups of subjects with prediabetes and determine the factors associated with those risks.
