[Analysis of infectious diseases care in Spanish hospitals from 2016-2020, including the first year of the SARS-CoV-2 pandemic]. / Análisis de la atención a patologías infecciosas en los hospitales españoles en el periodo 2016-2020, incluyendo el primer año de pandemia por SARS-CoV-2.

Aims: This work aimed to review patients discharged from Spanish hospitals with a principal diagnosis of infection during a 5-year period, including the first year of the SARS-CoV-2 pandemic. Materials and method: This work analyzed the Basic Minimum Data Set (CMBD) of patients discharged during the 2016-2020 period from hospitals in the Spanish National Health Service in order to identify cases with a principal diagnosis of an infectious disease according to the ICD-10-S code. All patients older than 14 years of age admitted to a conventional ward or intensive care unit, excluding labor and delivery, were included in the analysis and were evaluated based on the discharging department. Results: Patients discharged with infectious diseases as the principal diagnosis have increased from 10% to 19% in recent years. A large part of the growth is due to the SARS-CoV-2 pandemic. Internal medicine departments cared for more than 50% of these patients, followed by pulmonology (9%) and surgery (5%). In 2020, 57% of patients with a principal diagnosis of infection were discharged by internists, who cared for 67% of patients with SARS CoV-2. Conclusions: At present, more than half of patients admitted with a principal diagnosis of infection are discharged from internal medicine departments. Given the growing complexity of infections, the authors advocate for an approach in which training allows for specialization, but within a generalist context, for the better management of these patients.

Drug-induced hyponatremia: an updated review.

Hyponatremia, defined as serum sodium concentrations <135 mmol/L, is the most frequent electrolyte disturbance observed in both hospitalized and ambulatory patients, and has been associated to relevant negative consequences regarding morbidity and mortality. Drug-induced hyponatremia has been widely observed. However, since it may be clinically symptomatic or asymptomatic, it is frequently an underdiagnosed condition. This review aims to highlight the main drugs involved in the pathophysiology of hyponatremia, which should be considered in the differential diagnosis when approaching a patient with hyponatremia. We discuss their impact and relative importance. In order to prevent undesirable negative consequences we also emphasize the need for awareness of this clinically-relevant adverse effect, and we suggest how clinical management of patients may be approached.

[Description of hospital discharges in patients with systemic lupus erythematosus]. / Descripción de las altas hospitalarias en pacientes con lupus eritematoso sistémico.

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease that mainly affects young women and whose mortality is increasing for this age group. OBJECTIVES: We used the national registry of Hospital discharges in Spain based on the study of the Minimum Basic Data Set (MBDS) to analyze hospital discharges of patients whose diagnosis included that of LES. MATERIAL AND METHODS: A cross-sectional, descriptive study was performed of all episodes coded as having LES using ICD-9-MC coding system of the patients hospitalized within the period 2005-2008. RESULTS: A total of 5,464 episodes were identified, 1,855 (33%) as main diagnosis and 3,609 (66%) as secondary diagnosis. Patients having LES the main diagnosis were younger (41.56 ± 17.55 vs 56.07 ± 19.01 years; P < .001), had fewer elective admittances (62.5 vs 84.8%; P<.001), lower comorbidity as measured by the Charlson's index (Charlson>2; 18 vs 35%; P<.001) and lower mortality (1.1 vs 5.4%; P < .001). CONCLUSIONS: Patients admitted to internal medicine departments in Spain with a diagnosis of LES accounts for 0.3% of the total. Two different groups of patients are identified. The first group was younger, had lower comorbidity and were in the early phases of diagnosis and/or treatment. The second group was more numerous, older, with a higher comorbidity, with admittances frequently related to infections or cardiovascular complications and higher mortality rate.

[Adverse drug events in patients hospitalized in internal medicine]. / Acontecimientos adversos causados por medicamentos en pacientes ingresados en medicina interna.

OBJECTIVE: Adverse drug events (ADE) are a public health problem, the dimension of which is difficult to quantify because it is under-reported. We have aimed to identify and describe the ADEs recorded in the minimum basic data set (MBDS) of the Internal Medicine Services during the years 2005-7. PATIENTS AND METHODS: A cross-sectional study. Those episodes coded as such, according to the ICD-9-CM, in the discharge reports of all the patients hospitalized during 2005-07 in the entire Spanish territory, were selected. The sociodemographic variables, diagnostic categories and types of drugs, among others, were described and analyzed. RESULTS: Of the 1,567,659 discharges coded in the Minimum Basic Data Set" (MBDS), 96,607 ADEs were recorded in 86,880 episodes (5.55%). Of these 82.86% were not preventable and 17.14% were preventable. A total of 4.5% of the episodes recorded an adverse drug reaction (ADR). The ADE's were more frequent in women and the appearance of an ADR during admission was accompanied by an increase in the hospital stay. CONCLUSIONS: The MBDS is a useful tool for the identification, quantification and analysis of the ADRs, however, it is limited by the low recording of the discharge reports.

Collaborative hospital models for shared care and on-demand interconsultations. Which offer the best results for Orthopaedic Surgery and Trauma? / Modelos colaborativos hospitalarios de asistencia compartida e interconsultas a demanda. ¿Cuál ofrece mejores resultados en Cirugía Ortopédica y Traumatología?

BACKGROUND AND OBJECTIVES: Hospitalized surgical patients are increasing in medical complexity, thereby increasing the need for support by internal medicine departments. This support is provided through interconsultations, which present problems that have resulted in the development of shared care (SC). Our objective was to compare the healthcare results achieved by the SC and interconsultation models in Orthopaedic Surgery and Trauma. MATERIALS AND METHODS: We conducted an observational, prospective, multicentre study of patients hospitalized for emergency Orthopaedic Surgery and Trauma recorded in the REINA-SEMI registry, treated by internal medicine departments through interconsultation or SC. We recorded the demographic characteristics, comorbidity, medical complications, hospital stay and mortality. RESULTS: The study included 697 patients, 415 with SC and 282 with interconsultations. The SC patients were older (78.9 vs. 74.3; P<.001) underwent more operations (89.9 vs. 78.7%; P<.001), had fewer medical complications (50.4 vs. 62.8%; P<.001) and had shorter hospital stays (10 vs. 18 days; P<.001), with no differences in comorbidity or mortality. The following independent factors were associated with stays longer than 15 days: heart failure (OR 3.4; 95% CI 1.8-6.1; P<.001), the male sex (OR 1.9; 95% CI 1.2-3.1; P=.004), electrolyte disorder (OR 2.4; 95% CI 1.3-4.4; P=.003), respiratory infection (OR 1.9; 95% CI 1.04-3.7; P=.035), surgical delay (OR 1.1; 95% CI 1.08-1.2; P<.001) and treatment using the interconsultation on demand model (OR 3.5; 95% CI 2.3-5.4; P<.001). CONCLUSIONS: SC offers better healthcare results than interconsultations for patients hospitalized for emergency Orthopaedic Surgery and Trauma.

Utility of lateral flow tests in SARS-CoV-2 infection monitorization.

OBJECTIVE: The diagnosis of SARS-CoV-2 infection is crucial for medical and public health reasons, to allow the best treatment of cases and the best control of the pandemic. Serology testing allows for the detection of asymptomatic infections and 19-COVID cases once the virus has been cleared. We analyzed the usefulness of the SARS-CoV-2 rapid test of Autobio and tried to correlate its pattern with the severity of COVID19 infection. METHODS: We analyzed the accuracy and clinical usefulness of a point-of-care IgM and/or IgG test for SARS-CoV-2 in 35 COVID-19 patients [12 (34.3%) mild-moderate and 23 (65.7%) severe-critical] admitted to a field hospital in Madrid, as well as in 5 controls. RESULTS: The mean time from the first day of symptoms to the antibody test was 28 days (SD: 8.7), similar according to the severity of the disease. All patients with SARS-CoV-2 PCR+ showed the corresponding IgG positivity, while these results were negative in all control individuals. A total of 26 (74%) cases also presented with positive IgM, 19 (83%) were severe-critical cases and 7 (58%) were mild-moderate cases. The IgM response lasted longer in the severe critical cases (mean: 29.7 days; SD: 8.4) compared to the moderate cases (mean: 21.2 days; SD: 2.0).. CONCLUSIONS: Rapid serology tests are useful for the diagnosis of patients with COVID-19 (mainly IgG detection) and may also be correlated with the severity of the infection (based on IgM detection).

Metastatic spinal cord compression: Incidence, epidemiology and prognostic factors. / Compresión medular metastásica: incidencia, epidemiología y factores pronóstico.

BACKGROUND: Metastatic spinal cord compression (MSCC) is a severe complication in patients with cancer, and its incidence rate is difficult to accurately estimate. The aim of this study is to report the incidence and epidemiological and prognostic characteristics of MSCC in patients with cancer. MATERIAL AND METHODS: We analysed a cohort of 1736 patients diagnosed with cancer of any origin who were hospitalised in a palliative care unit. We collected epidemiological data, signs and symptoms, mean time to diagnosis, treatment regimen, response to treatment and mortality for the patients diagnosed with MSCC. RESULTS: In the 1736 patients, we identified 28 (1.6%) cases of MSCC. The average age was 67.2 (SD, 12.7) years, and lung cancer was the most common primary tumour (42.8%). The thoracic spine was the most affected location (12 cases, 42.8%), and pain was the predominant symptom (13 cases, 46.4%). The median survival after the MSCC diagnosis was 84.5 days. CONCLUSIONS: We observed an incidence rate of 1.6% (N=28) for MSCC in a cohort of 1736 patients with cancer. MSCC is a marker of poor prognosis, with a mean survival of less than 3 months from diagnosis and a hospital mortality of 32.4%.

Analysis of hospitalizations by cardiovascular disease in the population with diabetes in Spain. / Análisis de las hospitalizaciones por enfermedad cardiovascular en población diabética en España.

OBJECTIVES: Diabetes mellitus is associated with a marked increase in cardiovascular disease. In this study, we analysed the prevalence of diabetes mellitus in hospitalised patients in Spain in 2015 and the burden of associated cardiovascular disease. METHODS: By analysing the 2015 minimum basic data set (MBDS) of the Spanish Ministry of Health, we included all patients discharged with a diagnosis of diabetes mellitus. We describe the epidemiological characteristics, distribution by the various hospital departments and the presence of cardiovascular disease. RESULTS: In 2015, there was 3,727,583 hospital discharges in Spain, 619,188 of which involved patients with diabetes (16.7%), 56.8% of whom were men and with a mean age of 73.2years. The prevalence of cardiovascular disease was 40.8%, distributed among congestive heart failure (20.1%), cerebrovascular disease (10.3%), coronary artery disease (9.4%) and peripheral arterial disease (9.1%). Most of the patients were admitted to internal medicine (34.2%), cardiology (9.5%) and general surgery (8.9%) departments. The mean overall stay was 8.2days, the readmission rate at 30days was 14%, and the mortality rate was 6.8%. The patients hospitalized in internal medicine had higher severity levels (3-4) than those hospitalized in other medical departments (41.9% vs. 31.6%, respectively; P<.01) and those hospitalized in surgical departments (11.2%; P<.01). CONCLUSIONS: Diabetes mellitus is a significant comorbidity for patients hospitalized in internal medicine. A significant proportion of these patients present cardiovascular disease, mostly heart failure.

RECALMIN. Four years of growth of the internal medicine units of the Spanish National Health System (2013-2016). / RECALMIN. Cuatro años de evolución de las Unidades de Medicina Interna del Sistema Nacional de Salud (2013-2016).

OBJECTIVES: To compare the structure, resources and activity of the internal medicine units (IMUs) of the Spanish National Health System (SNHS) in 2013 and 2016. To analyse the differences between IMUs in 2016 by hospital size. MATERIAL AND METHODS: We conducted a comparison of 2 descriptive cross-sectional studies of IMUs in general acute care hospitals of the Spanish National Health System, with data referring to 2013 and 2016. The variables were collected via an ad hoc questionnaire (RECALMIN survey). RESULTS: Between 2013 and 2016, the demand for care increased dramatically (with an annual average of 11% in hospital discharges and 16% in first consultations), and comorbidity slightly increased (2%). During this period, the mean productivity of IMUs increased 16.7% (0.6±0.3 vs. 0.7±0.3; P=.09), and the mean stay decreased 10% (9±2.2 vs. 8.1±2.1 days; P=.001). Progress in implementing good practices and systematic care for complex chronic patients was scarce. Both surveys found variability among IMUs and marked differences among IMUs of hospitals of different sizes. CONCLUSIONS: IMUs responded to the increased burden of care they supported during 2013-2016 by improving their efficiency and productivity; however, advances in implementing good practices, including care for chronic complex patients, were scare. The significant variability in the indicators of structure, activity and management models found in 2013 remained in 2016.

RECALMIN II. Eight years of hospitalisation in Internal Medicine Units (2007-2014). What has changed? / RECALMIN II. Ocho años de hospitalización en las Unidades de Medicina Interna (2007-2014). ¿Qué ha cambiado?

OBJECTIVES: To analyse the evolution of care provided by the internal medicine units (IMU) of the Spanish National Health System from 2007 to 2014. MATERIAL AND METHODS: We analysed all discharges from the IMU of the Spanish National Health System in 2007 and 2014, using the Minimum Basic Data Set. We compared the risk factors by episode, mortality and readmissions between the two periods. We prepared specific fits for the risk for mortality and readmissions in heart failure, pneumonia and chronic obstructive pulmonary disease, as well as the Charlson index for all activity. RESULTS: Discharges from the IMU between the two periods increased 14%. The average patient age increased by 2.8 years (71.2±17.1 vs. 74±16.2; p<.001), with a marked increase in comorbidity (Charlson index, 4±3.7 vs. 4.7±3.9; p<.001; 24% increase in risk factors per episode). The adjusted mortality rates decreased slight but significantly, with a slight increase in readmissions. CONCLUSIONS: During the analysed period, there was an increase of almost 3 years in the mean age of patients treated in the IMU of the Spanish National Health System, with a marked increase in comorbidity. These results should lead to a more appropriate assignment of nurse workloads and an increased implementation of good practices in clinical management.

National survey on the activity of internists in shared care-interconsultations in spanish hospitals. / Encuesta nacional sobre la actividad de los internistas en asistencia compartida­interconsultas en los hospitales españoles.

OBJECTIVES: To analyse the activity of interconsultations conducted by the departments of internal medicine, communicating their importance to managers and offering information to these departments to improve their organisation. METHODS: A cross-sectional study was conducted using an interconsultation activity survey (on-demand consulting activity for other departments) and shared care (consulting activity provided in a regulated manner to other departments). RESULTS: We received 120 surveys that corresponded to 108 public and 12 private hospitals. Forty-five percent of the surveyed hospitals had a specialised interconsultation unit, and 31% had shared care. The department most frequently helped by the presence of a stable consultation unit (65% of the cases) was orthopaedic and trauma surgery. Fifty-five percent of the departments of internal medicine surveyed had an interconsultation activity record since the start of their activity. Ninety-two percent of the departments lacked a protocol that regulated interconsultations, and in 74% of the cases, the interconsultation was on demand. CONCLUSIONS: The interconsultation activity is generalised in the departments of internal medicine, but only 45% of these departments have interconsultation units, and only 33% provide the shared care modality. The survey reflects the shortcomings of training and some confusion in the concept of interconsultations. The considerable majority of departments lack organisational interconsultation protocols.

[Changes in the profile of HIV-positive patients. What has happened in the last 5 years?]. / Cambios en el perfil de los pacientes VIH positivos. Qué ha pasado en los últimos cinco años?

OBJECTIVE: To evaluate possible changes in the social, cultural and economical profile of our HIV infected patients appearing during the last five years and their potential impact on incidence, prevention, and follow-up of HIV infection. METHODS: We conduce a retrospective analysis of demographic, sociocultural, clinical and therapeutic characteristics of two groups of HIV infected patients reaching for the first time a level of 300 CD4 or less either in 1992 or in 1997. RESULTS: 55 patients with a mean age of 33 years (68% male 32% female) were studied. No differences were found in sexual behavior, HIV status of sexual partner, cultural level, risk practice, VHB or YHC seroprevalence. Attempts al drug quitting in 1992 were made individually and through institutional programs in 1997. Significant differences were found in the number of visits to the outpatient clinic the previous 36 months, and in de number of drugs (1.5 versus 3.5 P < 0.0001). Antirretroviral drugs were use in 62% of our 1992 patients and in 86% of the 1997 group (p < -0.02). CONCLUSIONS: The sociocultural and demographic profile has not changed in our environment in the last five years. However patients were identified later and followed less regularly at our clinic five years ago. Institutional methadone programs are the method or choice in our current patients for stopping illicit drug use. Finally treatment intensity has dramatically increased in our patients parallel to the growing therapeutical arsenal in this field.

[Sinistral portal hypertension with bleeding gastric varices as initial manifestation of renal-cell carcinoma]. / Hipertensión portal izquierda con sangrado por varices gástricas como forma de presentación de un hipernefroma.

We report a clinic case of renal-cell carcinoma presenting as sinistral portal hypertension; a clinical syndrome consisting of esplenic vein thrombosis manifested as isolated gastric varices with patent portal vein and normal hepatic function. The most frequent cause of this syndrome is pancreatic pathology. Renal-cell carcinoma is characterized by a wide variety of symptoms as initial manifestation. In our case, the patient developed a massive gastrointestinal bleeding secondary to isolated gastric varices caused by splenic vein thrombosis due to extrinsic compression by a hypernephroma that infiltrated the pancreas.
