OBJECTIVEnPrevention 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.nnnMETHODSnWe 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.nnnRESULTSnOf 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.nnnCONCLUSIONSnReadmissions 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.

AIMSnTo know the organization of internal medicine departments (IMD) and the opinion of their heads of department.nnnMETHODSnIn 2008, a survey was mailed to 410 heads of department of the IMD of 313 Spanish public hospitals. It included a standardized structured questionnaire on staff, hospitalization, outpatients, consultation, research and teaching. The heads of departments were also asked for their opinion and suggestions on management, projects and future.nnnRESULTSnSixty-eight surveys (22%) were filled out. Internists are on call an average of 3 times a month and perform 200 discharges, 500 outpatient visits and 40 consultations in a year. The average IMD consists of 10 internists with one-fifth of the hospital beds. One third of hospitals have alternatives to inpatient care, the most frequent being palliative care. Infectious diseases accounts for the most common monographic outpatient visit, one-third of IMD lack a structured relationship with primary care and the emergency department is independent of IMD. Half of the IMD have at least one IM resident and 6 residents in other specialties; half are involved in at least two clinical trials and one-third train medical students. The heads of the IMD identify problems in their relationship with hospital managers, other specialties and local population. Excessive workload, aging and discouragement of staff and patients social problems have negative effects. Even so, they want to initiate projects, are optimistic about the future and take an interest in clinical epidemiology research.nnnCONCLUSIONSnAlthough the sample is small and heterogeneous, it permits a valuable panoramic view of the structure and standard operation of a Spanish IMD as well as their expectations and areas of improvement.

Abstract 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% (nu2009=u200926,899) 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.

BackgroundThe aim of the present study is to analyze the incidence of hip fracture as a complication of admissions to internal medicine units in Spain.MethodsWe analyzed the clinical data of 2,134,363 adults who had been admitted to internal medicine wards. The main outcome was a diagnosis of hip fracture during hospitalization.Outcome measures included rates of in-hospital fractures, length of stay and cost.ResultsA total of 1127 (0.057%) admittances were coded with an in-hospital hip fracture. In hospital mortality rate was 27.9% vs 9.4%; pu2009<u20090.001, and the mean length of stay was significantly longer for patients with a hip fracture (20.7 days vs 9.8 days; pu2009<u20090.001). Cost were higher in hip-fracture patients (6927€ per hospitalization vs 3730€ in non fracture patients). Risk factors related to fracture were: increasing age by 10 years increments (OR 2.32 95% CI 2.11-2.56), female gender (OR 1.22 95% CI 1.08-1.37), admission from nursing home (OR 1.65 95% CI 1.27-2.12), dementia (1.55 OR 95% CI1.30-1.84), malnutrition (OR 2.50 95% CI 1.88-3.32), delirium (OR 1.57 95% CI 1.16-2.14), and anemia (OR 1.30 95%CI 1.12-1.49).ConclusionsIn-hospital hip fracture notably increased mortality during hospitalization, doubling the mean length of stay and mean cost of admission. These are reasons enough to stress the importance of designing and applying multidisciplinary plans focused on reducing the incidence of hip fractures in hospitalized patients.

OBJECTIVEnHospitalization of nursing home residents is costly and potentially exposes residents to iatrogenic disease and psychological harm.nnnDESIGN AND SETTINGnIn 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.nnnRESULTSnBetween 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).nnnCONCLUSIONSnTwo 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.

AIMSnInvasive procedures (IP) have become routine techniques that benefit an important number of patients on improving their quality of life or avoiding more aggressive treatments. We have conducted a study on the IPs performed in Spanish Internal Medicine (IM) Departments between 2005 and 2009.nnnPATIENTS AND METHODSnIP performed to patients admitted to Spanish Internal Medicine departments were analyzed based on the information obtained from the Minimum Basis Data Set (CMBD). IP was defined as the following: filter placement in the inferior vena cava, chest tube placement, biliary, esophageal and colon prosthesis placement, pleurodesis, nephrostomy, external biliary drain placement, gastrostomy tube placement, thoracocentesis and peritoneal catheter placement.nnnRESULTSnDuring the study period, a total of 75,853 invasive procedures on 70,239 admittances were performed in 2,766,673 patients (2.5%). IP subjects were younger (68.1 vs 71.4; P<.001), predominantly male (61.9 vs 53.2%; P<.001), with higher mortality (14.6 vs 9.9%; P<.001) and longer stay (18.4 vs 9.6 days; P<0.001). Cost of admittance was clearly higher than the rest of the patients (5,600€ vs 3,835€; P<.001).nnnCONCLUSIONSnIPs are performed on a low percentage of IM Department hospitalized patients. They are costly, entail high mortality and a longer stay period compared to the mean population admitted to IM. A considerable proportion of the patients receiving IP suffer from neoplastic diseases, frequently in advances stages, which justifies the high inhospital mortality of this population.

BACKGROUNDnHIV-immigrant use of health services and related cost has hardly been analysed. We compared resource utilisation patterns and direct health care costs between Spanish and immigrant HIV-infected patients.nnnMETHODSnAll HIV-infected adult patients treated during the years 2003-2005 (372 patients) in this hospital were included. We evaluated the number of out-patient, Emergency Room (ER) and Day-care Unit visits, and number and length of admissions. Direct costs were analysed. We compared all variables between immigrant and Spanish patients.nnnRESULTSnImmigrants represented 12% (n=43) of the cohort. There were no differences in the number of out-patient, ER, and day-care hospital visits per patient between both groups. The number of hospital admissions per patient for any cause was higher in immigrant than in Spanish patients, 1.3 (4.4) versus 0.9 (2.7), P=.034. A high proportion of visits, both for the immigrant (45.1%) and Spanish patients (43.0%), took place in services other than Infectious Diseases. Mean unitary cost per patient per admission, out-patient visits and ER visits were similar between groups. Pharmacy costs per year was higher in Spanish patients than in immigrants (7351.8 versus 7153.9 euros [year 2005], P=.012). There were no differences in the total cost per patient per year between both groups. The global distribution of cost was very similar between both groups; almost 75% of the total cost was attributed to pharmacy in both groups.nnnCONCLUSIONSnThere are no significant differences in health resource utilisation and associated costs between immigrant and Spanish HIV patients.

This update to the document on antiretroviral therapy (ART) in adults, which has been prepared jointly by GeSIDA and the Spanish National AIDS Plan for the last two decades, supersedes the document published in 2017.1 The update provides physicians treating HIV-1-infected adults with evidence-based recommendations to guide their therapeutic decisions. The main difference with respect to the previous document concerns recommended initial ART regimens, only three of which are maintained as preferential. All three include dolutegravir or raltegravir, together with emtricitabine/tenofovir alafenamide or abacavir/lamivudine. Other differences concern the section on switching ART in patients with suppressed viral replication, which now includes new two- and three-drug regimens, and the antiretroviral drugs recommended for pregnant women and patients with tuberculosis. A recommendation has also been added for patients who present with acute HIV infection after pre-exposure prophylaxis.

Opportunistic infections continue to be a cause of morbidity and mortality in HIV-infected patients. They often arise because of severe immunosuppression resulting from poor adherence to antiretroviral therapy, failure of antiretroviral therapy, or unawareness of HIV infection by patients whose first clinical manifestation of AIDS is an opportunistic infection. The present article is an executive summary of the document that updates the previous recommendations on the prevention and treatment of opportunistic infections in HIV-infected patients, namely, infections by parasites, fungi, viruses, mycobacteria, and bacteria, as well as imported infections. The article also addresses immune reconstitution inflammatory syndrome. This document is intended for all professionals who work in clinical practice in the field of HIV infection.

Despite the huge advance that antiretroviral therapy represents for the prognosis of infection by the human immunodeficiency virus (HIV), opportunistic infections (OIs) continue to be a cause of morbidity and mortality in HIV-infected patients. OIs often arise because of severe immunosuppression resulting from poor adherence to antiretroviral therapy, failure of antiretroviral therapy, or unawareness of HIV infection by patients whose first clinical manifestation of AIDS is an OI. The present article updates our previous guidelines on the prevention and treatment of various OIs in HIV-infected patients, namely, infections by parasites, fungi, viruses, mycobacteria, and bacteria, as well as imported infections. The article also addresses immune reconstitution inflammatory syndrome.
