Long-term mental health resource utilization and cost of care following group psychoeducation or unstructured group support for bipolar disorders: a cost-benefit analysis.

OBJECTIVE: To explore the short- and long-term mental health resource utilization and cost of care in a sample of 120 individuals with bipolar disorders who participated in a randomized controlled efficacy trial of group psychoeducation versus unstructured group support. METHOD: Prospective, independent monitoring of DSM-IV bipolar disorder type I or II patients aged 18 to 65 years was conducted during the intervention phase (6 months) and follow-up phase (5-year postintervention) of a randomized controlled trial reporting clinical outcomes and inpatient and outpatient mental health service utilization, with estimation of cost of treatment per patient. The study was conducted from October 1997 through October 2006. RESULTS: Compared with individuals with bipolar disorder receiving the control intervention, psychoeducated patients had twice as many planned outpatient appointments, but the estimated mean cost of emergency consultation utilization was significantly less. There were trends for psychoeducated patients to opt for self-funded psychotherapy after completing group psychoeducation and to utilize more medications. However, inpatient care accounted for 40% estimated total cost in the control group but only about 15% in the psychoeducation group. CONCLUSIONS: This study demonstrates the importance of taking a long-term overview of the cost versus benefits of adjunctive psychological therapy in bipolar disorders. If viewed only in the short-term, the psychoeducation group used more mental health care resources without clear additional health gain. However, extended follow-up demonstrated a long-term advantage for psychoeducated individuals, such that, compared to an unstructured support group intervention, group psychoeducation is less costly and more effective.

[Validation of the EuroSCORE probabilistic model in patients undergoing coronary bypass grafting]. / Validación del modelo probabilístico EuroSCORE en pacientes intervenidos de injerto coronario.

INTRODUCTION AND OBJECTIVES: EuroSCORE utilizes a probabilistic model for predicting the risk of in-hospital mortality in patients undergoing cardiac surgery. It is a useful instrument for evaluating quality of care. The model has two variants: the logistic EuroSCORE and the additive EuroSCORE. The aim of this study was to validate the EuroSCORE model in patients undergoing surgery at Hospital Clínic in Barcelona, Spain, and to compare the results obtained with the two variants. METHODS: The study included all patients who received a coronary artery bypass graft (CABG) at Hospital Clínic in Barcelona in two consecutive years. The model's validity was assessed on the basis of its calibration (using the Hosmer-Lemeshow test) and its discrimination (using the receiver operating characteristic [ROC] curve). The two models were compared by carrying out a descriptive analysis of mortality for the whole group and for different risk groups, and by determining the models' discriminative power. RESULTS: A total of 498 patients underwent CABG surgery and were included in the study. The Hosmer-Lemeshow test showed that the model's calibration was satisfactory (P=.32) and the area under the ROC curve was 0.83. The observed in-hospital mortality rate was 5.8%. The predicted rate was 4.2% with the logistic EuroSCORE and 3.9% with the additive EuroSCORE. Large differences were observed in high-risk patients. In these patients, the mortality predicted by the logistic variant was closer to the actual mortality. CONCLUSIONS: EuroSCORE's validity was found to be satisfactory and the model can be used to evaluate quality of care. In high-risk patients, mortality estimated using the logistic model was closer to the actual mortality.

Induction therapy with trizivir plus efavirenz or lopinavir/ritonavir followed by trizivir alone in naive HIV-1-infected adults.

BACKGROUND: Induction-maintenance strategies were associated with a low response rate. We compared the virological response with two different induction regimens with trizivir plus efavirenz or lopinavir/ritonavir. METHODS: A randomized, multicentre, open-label clinical trial with 209 antiretroviral-naive HIV-infected patients assigned to trizivir plus either efavirenz or lopinavir/ritonavir during 24-36 weeks. Patients reaching undetectable plasma viral loads during induction entered a 48-week maintenance on trizivir alone. The primary endpoint was the proportion of patients without treatment failure at 72 weeks using an intent to treat (ITT) analysis (switching equals failure). RESULTS: Patients were randomly assigned (efavirenz 104; lopinavir/ritonavir 105), and 114 (55%) entered the maintenance phase (efavirenz 54; lopinavir/ritonavir 60). Baseline characteristics were balanced between groups. The response rate at 72 weeks was 31 and 43% (ITT analysis, P = 0.076) and 63 and 75% (on-treatment analysis, P = 0.172) in the efavirenz and lopinavir/ritonavir arms, respectively. Virological failure occurred in 27 patients: six during induction (efavirenz, three; lopinavir/ritonavir, three; P = 1.0) and 21 during maintenance (efavirenz, 14; lopinavir/ritonavir, seven; P = 0.057). Thirty-four patients in the efavirenz arm switched treatment because of adverse events compared with 25 in the lopinavir/ritonavir arm (P = 0.17). CONCLUSION: Trizivir plus either efavirenz or lopinavir/ritonavir followed by maintenance with trizivir achieved a low but similar response at 72 weeks, with a high incidence of adverse events leading to drug discontinuation during the induction phase in both arms. The study showed a trend towards an increased virological failure rate in the efavirenz arm during the maintenance phase.

[Not Available]. / Organización en institutos de gestión clínica (centros orientados al paciente): descripción de la utilización hospitalaria.

OBJECTIVES: To assess the main features and determining factors of inappropriate admission and hospital stay in relationship with a new clinical management model. METHODS: Study population included all patients discharged from the Hospital Clinic-University of Barcelona. The review tool was the medical and surgical Appropriateness Evaluation Protocol (AEP). We reviewed the clinical records of a representative sample of all discharged patients. Two independent and well trained AEP reviewers were used for each record review. A multivariate analysis was performed, using admission and inappropriate hospital stay as independent variables. RESULTS: A total of 401 admissions were reviewed. Twenty-eight (6.9%) were deemed to be inappropriate. Elective admission, admission over the week-end and being admitted to a medical ward were the predictive variables identified for inappropriate admissions. Of all 2,187 hospital stays reviewed, 267 (12.2%) were deemed to be inappropriate. An inappropriate admission, total length of stay, type of insurance coverage and discharge type were the predictive variables identified for inappropriate hospital stays. CONCLUSIONS: The new organization and clinical management model, developed by the Patient Focused Care Institutes, showed very acceptable levels of inappropriate admissions and hospital stays. Surgical services have benefited most from this new organization. Care provided to patients with medical conditions, notably those patients with multiple and chronic conditions, make up most of the inappropriateness identified.

[Estimation of emergency department activity and its relationship with inhospital bed disposition]. / Estimación de la actividad en urgencias y su relación con la provisión de camas de hospitalización.

BACKGROUND AND OBJECTIVE: To find out if the daily emergency department (ED) census and daily ED admittances can accurately be foreseen based on the number of visits arrived on ED within the first shift hours. PATIENTS AND METHOD: For 6 consecutively months, the number of ED visits from 6 AM to 10 AM (early visits), and from 10 AM to next day 6 AM (daily ED census) was recorded, along with the number of both daily hospital and ED admittances from 6 AM to 6 AM. The analysis was performed for the ED as a whole, and for each one of its sections. RESULTS: A significant direct correlation was seen between the early visits and daily ED census. This relationship was even greater as considered the ED as a whole (R2 = 0.25; p < 0.001). A direct correlation was also found between daily ED census and daily admittances (R2 = 0.19; p < 0.001). CONCLUSIONS: The number of early ED visits is an important tool to accurately predict the daily ED census and the number of in-hospital beds needed for ED patients.

[Cost analysis of cardiac transplantation in a Spanish hospital]. / Análisis del coste del trasplante cardíaco en un hospital español.

BACKGROUND AND OBJECTIVE: Heart transplant requires a heavy use of high cost resources. Economic data related to this procedure had not been specifically addressed and there are very few publications which analyze this topic. The aim of this study was to analyze the costs related to heart transplant in a series of patients from a single institution. PATIENTS AND METHOD: Data from all patients included in the Hospital Clínic heart transplant programme in which a cardiac transplant was effectively performed between 1999 and 2000 were analyzed, including one year of follow-up. Patients who died within this first year were also included. Organ procurement costs were excluded. Cost analysis was performed by micro-costing techniques. RESULTS: A total of 21 patients undergoing a heart transplant were included. One year survival rate was 76%. Mean (standard deviation) of total cost (procedure costs + one year follow-up cost) was 59,349 (18,881) euros (range: 29,380-113,470 euros). Procedure mean cost was 41,724 (17,584) euros (70% of total costs) and one year follow up mean cost was 17,625 (10,096) euros (30% of total costs) per patient. When the initial episode (heart transplant procedure) was analyzed, main cost drivers were personnel costs euros 59% of all costs; mean: 24,795 (7,633) euros and treatment costs -20% of all costs; mean: 8,386 (7,250) euros. CONCLUSIONS: Costs of heart transplant in Barcelona (Spain) are similar to those published for other European Union countries, and well below the costs related to the procedure in the United States.

[Analysis of Spanish hospital's reputation: relationship with their scientific production in different subspecialities]. / Análisis de la reputación de los hospitales españoles: relación con su producción científica en cuatro especialidades.

BACKGROUND AND OBJECTIVE: To assess the relationship between reputation of hospitals, as determined by specialists' opinion, and their scientific production. MATERIAL AND METHOD: A questionnaire was sent to a sample of members of the Spanish Societies of Cardiology, Digestive Diseases, Neurology and Otorhinolaryngology. Each member had the possibility to nominate 5 hospitals with the greatest reputation amongst his/her specialty. Final score for those hospitals with more than 5% of all votes was used for the development of a reputation index. We assess the scientific production (number of publications and citations) for nominated hospitals and analyze the possible correlation between the reputation index and the scientific production. RESULTS: We received 151 (30%) answers for cardiology, 227 (27%) for digestive diseases, 148 (30%) for neurology and 177 (18%) for otorhinolaryngology. The number of published articles and the number of citations for each nominated hospital showed a positive and statistically significant correlation with the reputation index. CONCLUSIONS: This is the first approach to analyze reputation parameters for Spanish hospitals. Scientific production and reputation index showed a positive correlation.

[Direct discharge from triage in emergency departments: assessment, risks and patient satisfaction]. / Derivación sin visita desde los servicios de urgencias hospitalarios: cuantificación, riesgos y grado de satisfacción.

BACKGROUND AND OBJECTIVE: After triage assessment, some hospitals refer emergency department (ED) patients with minor chief complaints to off-site clinics. The potential for 2 different referral models introduced in 2 urban hospitals was assessed, as well as the suitability of this measure. PATIENTS AND METHOD: After triage assessment, patients with minor complaints were identified. ED from Hospital Clínic of Barcelona (HCB) proposed that these patients should be referred to a hospital affiliated off-site clinic, whereas ED from Hospital Mútua de Terrassa (HMT) tried to refer such patients to their primary care setting. Within a year, we assessed on both ED the following items: number of arrivals, percentage of proposed referrals (PR), percentage of accepted referrals (AR), percentage of carried-out referrals (CR: patients who, once discharged, really attended the other setting), and percentage of returned referrals (RR) to the ED, as well as return reasons, and the percentage of returned patients finally admitted. The degree of patient satisfaction was evaluated by means of a telephone survey. RESULTS: From both ED, 44,764 arrivals and 7,297 (16.3%) PR were registered. The percentage of AR and CR was 94.3% and 75.3%, respectively. The percentage of PR from HMT was higher (18.7% vs 13.1%; p < 0.001), yet HCB obtained a greater percentage of AR (98.9% vs 92%, p < 0.001) and CR (93.7% vs 65%; p < 0.001). The percentage of RR from both ED was 1.5% (2.8% vs 0.4%; p < 0.001). Among returned patients, 12 of them (0.17% respect to AR) were finally admitted. Only 41% of patients who were found to be eligible for direct discharge would have agreed with being referred to another clinical setting, but after the experience, up to 93% of them said they would go through it again. HMT gave referral information to patients faster than HCB (p < 0.05), but HCB got a better model evaluation (p < 0.01), a greater medical complaint solution (p < 0.05), and generated a smaller number of subsequent consultations (p < 0.05). CONCLUSIONS: After a rapid triage assessment, a percentage of patients arriving on EDs may be directly and safely discharged and referred to other clinical settings. This is achieved by both proposed models without additional risks for patients. However, patients feel more satisfied with an hospital-affiliated off-site clinic instead of their primary care setting.

[Emergency department activity during the 2003 summer heat wave]. / Impacto de la ola de calor del verano de 2003 en la actividad de un servicio de urgencias hospitalario.

BACKGROUND AND OBJECTIVE: Several thousands deaths were attributed to a heatwave during the summer of 2003 in Europe. The aim of this study was to analyze its consequences in an emergency department. PATIENTS AND METHOD: We performed a descriptive observational study of the patients admitted to our emergency unit between 15 July and 31 August, 2003. We also carried out a comparative study of these patients with those admitted during the same period of 2002. RESULTS: A total of 5197 patients were admitted in our unit during the summer of 2003, in comparison with 4672 in the same interval in 2002. An increase in rates of total fever (17% versus 12%; p < 0.001), non-infectious fever (29% versus 26%; p < 0.001), decompensation of a chronic cardiovascular or respiratory disease (14% versus 11%; p < 0.001), admission (28% versus 22%; p < 0.001), and mortality (2% versus 1%; p < 0.001) were registered during the summer of 2003, in comparison with the previous year. A multivariate study showed a higher risk of death in patients older than 70 years (p < 0.01), in fragile dependent people (p < 0.05), and upon the presence of abnormal blood levels of creatinine (p < 0.05) on arrival at the emergency department. We also found an association between daily maxim temperature and number of daily emergency visits (R2 = 0.15; p < 0.001), total percentage of patients with fever (R2 = 0.26; p < 0.001), percentage of patients with non-infectious fever (R2 = 0.07; p = 0.01), percentage of decreases (R2 = 0.04; p < 0.05), and percentage of hospital admissions (R2 = 0.15; p < 0.001). CONCLUSIONS: The summer 2003 heatwave resulted in an elevation of the total number of emergency visits and hospital admissions, and higher mortality and morbidity rates, especially in old people. In the future, preventive measures must be taken to limit the health consequences of any heatwaves to come.

[Usefulness of risk indexes for the prediction of surgical site infection in patients undergoing neurosurgical procedures]. / Utilidad de los índices compuestos de riesgo para predecir el desarrollo de infección quirúrgica en neurocirugía.

BACKGROUND AND OBJECTIVE: The use of risk indexes, originally developed in the US for the assessment of SSI risk, is an useful instrument that must be analyzed according to each specific procedure. The addition of other possible SSI risk factors, like the use of perioperative antibiotic prophylaxis, could improve the predictive value of these indexes. The aim of this study was to determine the SSI incidence rate for craniotomy in patients admitted to the Neurosurgical Unit of the Hospital Clinic of Barcelona (Spain), to assess the use of standard NNIS and SENIC indexes, and to assess the possible effect of the addition of a new risk factor (adequate or inadequate use of perioperative antibiotic prophylaxis) to these indexes. PATIENTS AND METHOD: Risk factors for SSI were assessed following common standard definitions and procedures (CDC-NNIS) over a three-year period (1999-2001). NNIS and SENIC risk indexes were calculated. The effect of the addition of a new variable, namely perioperative antibiotic prophylaxis adequate (0 points) or inappropriate/no prophylaxis (1 point) on these indexes (modified indexes NNISa and SENICa) was also assessed. Statistical analysis included both parametric and non-parametric standard tests. RESULTS: The study included a total of 203 patients undergoing a craniotomy procedure (40% of all neurosurgical procedures). The overall SSI incidence rate was 6.8% (14 patients developed SSI). The cut-off point (75 percentile) for the duration of the procedure was 180 minutes instead of the commonly US reported 240 minutes. Patients who develop SSI had a trend towards having shorter operation times. For those patients in the lower risk groups, the SSI incidence rate was: NNIS (0, 1): 6.9%; SENIC (0, 1): 6.2%. If the modified indexes were used, the SSI incidence rate was: NNISa (0, 1): 4.2%; SENICa (0, 1): 4.9%. When NNIS and SENIC indexes, both standard and modified (NNISa and SENICa), were compared, no statistically significant differences between infected and non-infected patients were observed. CONCLUSIONS: When applied to a health system other than the US, SENIC and NNIS indexes could be useful if adapted to each specific situation and procedure. The added value of a new risk factor (perioperative antibiotic prophylaxis) on standard NNIS and SENIC indexes shows a slight improvement in their prediction rate for SSI in patients undergoing craniotomy, mainly in those patients at lower risk for developing superficial SSI.

[Influence of the time factor on hospitalised patient's opinion]. / Influencia del factor tiempo en la opinión del paciente hospitalizado.

BACKGROUND AND OBJECTIVE: An important controversy at the time of studying the perceived quality is which is the best time to know the patient's opinion. The objective of this work was to find out whether this opinion is different at the time of discharge and one month later. PATIENTS AND METHOD: We included patients who were discharged between October 1999 and March 2000. We designed a specific opinion survey with 44 items. The survey was administered at the time of discharge. Individuals who responded to the first survey were sent the same one by e-mail 30 days after the discharge. RESULTS: The first survey was responded by 1,061 subjects and the second one by 485 (45.71%). Overall, answers from subjects who responded the survey in both phases showed a 65% agreement rate and a 35% disagreement rate. On the other hand, 84% of questions showed answers with a low agreement's Kappa index, while 6% had a good agreement. CONCLUSION: Globally considered, the average satisfaction expressed by subjects was equivalent in the two phases of the study, yet the individual degree of satisfaction varied.

[Emergency department discharge reports as a management tool of clinical information]. / Evaluación de los informes de asistencia de urgencias como instrumento de gestión de la información clínica.

BACKGROUND AND OBJECTIVES: Our goal was to assess the degree of readability, quality and amount of information included in discharge reports of Emergency Departments (ED) in order to evaluate their usefulness for the management of clinical information. MATERIAL AND METHOD: Analysis of a sample of ED discharge reports from 6 Barcelona hospitals (Hospital General Vall d'Hebron, Hospital Clínic de Barcelona, Institut Municipal d'Assistència Sanitària [IMAS] hospitals, Hospital Germans Trias i Pujol and Hospital Sant Joan de Déu). We assessed their readability together with the information included for the development of an ED Uniform Discharge Data Set (CMBDAU). RESULTS: 11,188 ED discharge reports were analyzed. Overall, 39% reports were found to have enough and readable information. However, the interpretation of the written information was deemed to be fairly difficult in 46% cases and very difficult in the remaining 15% reports. CONCLUSIONS: Formal quality and comprehensiveness of the information included in ED discharge reports is a critical factor for the precision and usefulness of any registry of data and ED patients classification systems.

[Central-venous catheter-related infections and intensive care unit organization systems (EPIC Study, Spain)]. / Infecciones relacionadas con el uso de catéteres venosos centrales y sistemas organizativos de las unidades de cuidados intensivos (estudio EPIC).

BACKGROUND AND OBJECTIVE: Central venous catheter (CVC)-related nosocomial bacteremia is an important problem at the ICU. The possible role of organizational factors, as well as health care workers experience, for developing these infections is not well known. We aimed to identify the possible relationships and differences between the health care process, organizational features of the institutions and the development of CVC-related nosocomial infections. We also compared the results of the Spanish participating hospital with those of an international group of hospitals. PATIENTS AND METHOD: The EPIC study (Evaluation of Processes and Indicators in Infection Control) includes a total of 56 hospitals from different countries. The Hospital Clínic of Barcelona was the only Spanish participant. Each Hospital selects, by means of a random process, 5 ICU patients per month with a recently placed CVC. Data related to the CVC insertion process, follow-up and care of the CVC, time dedication of nursing personnel, days of stay and episodes of CVC-related bacteremia per 1000 patient-days of CVC use were recorded. RESULTS: A total of 3,298 patients with a CVC were included, and 89 episodes of CVC-related nosocomial bacteremia were identified (3.86 episodes per 1000 CVC-days). The Hospital Clínic included 67 patients with a CVC and identified 1.96 episodes of CVC-related nosocomial bacteremia per 1000 CVC-days. When compared to the international group of hospitals, the Spanish centre used sterile drapes more frequently for fixing the CVC (70% vs. 23%), each Health Care Worker inserted fewer CVC (average over last 6 months: 24 vs 50) and CVC were more frequently inserted by Registered Nurses (48% vs. 4%). The type of CVC more commonly used in Spain was a peripherically-inserted CVC (48% vs. 6%), and the CVC was withdrawn from patients less commonly before discharge from the ICU (16% vs. 43%). Mean total number of hours of nursing dedication was lower in Spain, with lower personnel ratios (number of nurses' hours) per day of stay (12 vs. 15). CONCLUSIONS: The EPIC study provides a valid tool for assessing the results of the process of health care, and for linking the outcomes to this process. The results registered at the Spanish hospital seem to be adequate, yet some differences in the health care process are identified.
