Objective: Hospitalization of nursing home residents is costly and potentially exposes residents to iatrogenic disease and psychological harm. Design and setting: In this study, we analyzed the data from the Basic Minimum Data Set of patients hospitalized from the nursing home who were discharged from all the internal medicine departments at the National Health Service hospitals in Spain between 2005 and 2008, according to the data provided by the Ministry of Health and Consumer Affairs. Results: Between January 2005 and December 2008, 2,134,363 patients were admitted to internal medicine departments in Spain, of whom 45,757 (2.1%) were nursing home residents. Overall, 7898 (17.3%) patients died during hospitalization, 2442 (30.91%) of them in the first 48 hours. The following variables were the significant predictors of in-hospital mortality in multivariate analysis: age (odds ratio [OR] 1.02, 95% confidence intervals [CI] 1.02-1.03), female gender (OR 1.13, 95% CI 1.13-1.17), dementia (OR 1.09, 95% CI 1.03-1.16), previous feeding tube (OR 1.34, 95% CI 1.09-1.79), malignant disease (OR 2.03, 95% CI 1.86-2.23), acute infectious disease (OR 1.18, 95% CI 1.12-1.25), pressure sores (OR 1.88, 95% CI 1.62-1.95), acute respiratory failure (OR 2.00, 95% CI 1.90-2.10), and nosocomial pneumonia (OR 2.5, 95% CI 2.23-2.72). Conclusions: Two of every 100 patients admitted to internal medicine departments came from nursing homes. The rate of mortality is very high in these patients, with almost one third of patients dying in the first 48 hours, which suggests that many of these transfers were unnecessary. The cost of these admissions for 1 year was equivalent to the annual budget of a 300- to 400-bed public hospital in Spain. The mechanism of coordination between nursing homes and public hospitals must be reviewed with the aim of containing costs and facilitating the care of patients in the last days of life.

(Sage, 2010-07) Barba, Raquel; Marco Martinez, Javier; Plaza, Susana; Losa, Juan Emilio; Canora, Jesús; Zapatero, Antonio
The management of patients admitted during weekends may be compromised because the level of staffing in the hospital is often lower then. This study was conducted to assess what independent influence, if any, weekend admission might have on inhospital mortality. The authors analyzed the clinical data of 429,880 adults >14 years of age who were admitted to internal medicine wards in Spain after having presented to the hospitals' emergency departments. Overall mortality and early mortality (occurring in the first 48 hours) were examined, taking into account whether a patient was admitted on a weekend or a weekday, in addition to other parameters. Weekend admissions were associated with a significantly higher inhospital mortality than weekday admissions among patients admitted to an internal medicine service (odds ratio [OR] = 1.1; 95% confidence interval [CI] = 1.14-1.08). Differences in mortality persisted after adjustment for age, sex, and coexisting disorders (OR = 1.071; 95% CI = 1.046-1.097). Analyses of deaths within 2 days after admission showed larger relative differences in mortality between weekend and weekday admissions (OR = 1.28; 95% CI = 1.22-1.33). For patients admitted to an internal medicine service via an acute care visit to the emergency room, admission on weekends is associated with higher mortality than admission during the week.
Anemia in chronic obstructive pulmonary disease: a readmission prognosis factor
(Taylor & Francis, 2012-03-28) Barba, Raquel; García de Casasola, Gonzalo; Marco, Javier; Losa, Juan Emilio; Plaza, Susana; Canora, Jesús; Zapatero, Antonio
Objective: The prevalence of comorbid anemia in patients with COPD ranges from 7.5% to 34%. The aim of this study is to determine if anemia is a risk factor for readmission in COPD patients. Methods: This study analyzed the hospital data of 289,077 adults with acute exacerbations of COPD admitted to the hospital at any public center in Spain, in 2006 and 2007. We calculated the prevalence of anemia and compared readmissions between COPD patients with and without anemia. Multiple regression analyses were carried out with the aim of determining the risk of readmission attributable to anemia, after the correction of possible confounding variables. Results: Of the patients with COPD, 9.8% (n = 26,899) had a diagnosis of anemia. Anemic patients were older, more likely to be female and had a greater comorbidity burden than non-anemic individuals. Multiple regression modeling revealed that multiple independent factors were associated with an increased risk of readmission in persons with COPD. Anemia was one of the greatest risks: anemic patients had a 25% higher risk of readmission than non-anemic patients (odds ratio [OR], 1.25; 95% confidence interval [CI] 1.21-1.29). Conclusion: Utilizing an administrative database the authors found that anemia correlates independently with readmission in COPD patients. Limitations: This is a retrospective cohort study and thus subject to multiple forms of bias. Although spirometric evidence of COPD was not available, our case identification methods have been previously validated and found to be accurate in recognizing COPD.
Mortality and complications in very old patients (90+) admitted to departments of internal medicine in Spain
(Elsevier, 2011-02) Barba, Raquel; Marco Martinez, Javier; Zapatero, Antonio; Plaza, Susana; Losa, Juan Emilio; Canora, Jesus; Perez, Alejandro; García de Casasola, Gonzalo
Summary: Patients over 90 years of age (the "very elderly") account for an increasing number of admissions to departments of internal medicine (IM). The aim of this study was to analyse the demographic data, hospitalization characteristics, medical complications, and predictors of mortality in patients over 90 admitted to IM departments. Material and methods: All patients admitted to IM departments in Spain between the years 2005 and 2007 were analysed. Clinical and demographic data were compared with records from "younger elderly" patients (65-90). Results: During the study period, there were 1,567,659 patient admissions to IM departments in Spain, and 90,679 (5.8%) were older than 90. Hospital mortality occurred in 22.3% of very elderly patients. The main predictors for hospital death were pressure ulcer (Odds Ratio [OR] 1.55, CI95% 1.45-1.66), thromboembolic disease (OR 1.83, CI95% 1.61-2.09), nosocomial pneumonia (OR 2.53, CI95% 2.39-2.69), hip fracture (OR 2.20, CI95% 1.53-3.18), male gender (OR 1.06, CI95% 1.03-1.10), age (OR 1.05, CI95% 1.04-1.06), dementia (OR 1.13, CI95% 1.08-1.18), cancer (OR 1.60, CI95% 1.51-1.71), acute respiratory failure (OR 1.83, CI95% 1.76-1.89), acute infectious disease (OR 2.30, IC95% 2.11-2.52), and Charlson comorbidity index (OR 1.21, CI95% 1.16-1.26). Conclusions: Very elderly patients represent a large and growing fraction of the total admissions to IM departments in Spain. They are at higher risk for complications during their hospital stay and mortality rate is double that of the younger elderly.

-Objective: Prevention of readmission to hospital is considered an outstanding example of a cost-effective practice. Our aim was to derive and validate a clinically useful index to quantify the risk of readmission among patients discharged from Internal Medicine departments. Methods: We analysed hospital Basic Minimum Data Sets (BMDS) recorded between 2006 and 2008 to determine patterns of rehospitalization. Multivariate statistical analysis of routinely collected data was used to develop an algorithm ('SEMI INDEX') to identify patients predicted to have the highest risk of readmission in the 30 days following discharge. The algorithm was developed by using data from admissions in 2006-2007, for four age subgroups. Coefficients for the most powerful and statistically significant variables were applied against episodes recorded in 2008 to validate the findings of the algorithm developed from the first sample. Results: Of the 999,089 internal medicine admissions in Spain during 2006-2007, 12.4% were rehospitalized within 30 days. The key factors that predicted subsequent admission included male sex, length of stay, comorbidity of the patient, and some clinical conditions. There were small but relevant differences among the different age subgroups. Conclusions: Readmissions to Internal Medicine departments are prevalent (12.4%). The SEMI INDEX can be used to assess accurately the risk of readmission within 30 days after discharge.
The impact of weekends on outcome for acute exacerbations of COPD
(European Respiratory Society, 2012-01) Barba, Raquel; Zapatero, Antonio; Losa, Juan Emilio; Marco, Javier; Plaza, Susana; Rosado, Cristina; Canora, Jesús
Differences in hospital staffing may influence outcomes for patients with acute conditions, including acute exacerbations of chronic obstructive pulmonary disease (COPD), depending on which day of the week the patients are admitted. This study was conducted to determine whether weekend admission increases the risk of dying in hospital. We analysed the clinical data of 289,077 adults with acute exacerbations of COPD admitted to the hospital at any public centre in Spain, during 2006 and 2007. We analysed the following factors for their association with death rate: day of admission, demographics, medical history and comorbidity. During the study period, there were 35,544 (12.4%) deaths during admission in COPD patients. Weekend admissions were associated with a significantly higher in-hospital mortality (12.9%) than weekday admissions (12.1%) among COPD patients (OR 1.07 (95% CI 1.04-1.10)). The differences in mortality persisted after adjustment for age, sex and coexisting disorders (OR 1.05 (95% CI 1.02-1.08)). Analyses of deaths within 2 days after admission showed larger relative differences in mortality between the weekend and weekday admissions (OR 1.17 (95% CI 1.11-1.23)). We conclude that patients with acute exacerbations of COPD are more likely to die in the hospital if they are admitted on a weekend compared with a weekday.
