[Validity and usefulness of the RAE-CMBD studying patients hospitalised with influenza]. / Validez y utilidad del RAE-CMBD en el estudio de los pacientes hospitalizados con gripe.

OBJECTIVE: Understanding the hospital impact of influenza requires enriching epidemiological surveillance registries with other sources of information. The aim of this study was to determine the validity of the Hospital Care Activity Record - Minimum Basic Data Set (RAE-CMBD) in the analysis of the outcomes of patients hospitalised with this infection. METHODS: Observational and retrospective study of adults admitted with influenza in a tertiary hospital during the 2017/2018 and 2018/2019 seasons. We calculated the concordance of the RAE-CMBD with the influenza epidemiological surveillance registry (gold standard), as well as the main parameters of internal and external validity. Logistic regression models were used for risk adjustment of in-hospital mortality and length of stay. RESULTS: A total of 907 (97.74%) unique matches were achieved, with high inter-observer agreement (ƙ=0.828). The RAE-CMBD showed a 79.87% sensitivity, 99.72% specificity, 86.71% positive predictive value and 99.54% negative predictive value. The risk-adjusted mortality ratio of patients with influenza was lower than that of patients without influenza: 0.667 (0.53-0.82) vs. 1.008 (0.98-1.04) and the risk-adjusted length of stay ratio was higher: 1.15 (1.12-1.18) vs. 1.00 (0.996-1.001). CONCLUSIONS: The RAE-CMBD is a valid source of information for the study of the impact of influenza on hospital care. The lower risk-adjusted mortality of patients admitted with influenza compared to other inpatients seems to point to the effectiveness of the main clinical and organisational measures adopted.

Complicaciones de la gripe: información sobre eventos cardíacos a través de un sistema de vigilancia hospitalario / Influenza complications: Reporting cardiac events through a hospital surveillance system

Antecedentes y objetivo: El objetivo de este estudio fue determinar las complicaciones de la gripe en todos los adultos hospitalizados con esta enfermedad y, de forma específica, analizar las características de los eventos cardiovasculares posinfección.Metodología: Estudio observacional y descriptivo de los episodios de gripe en adultos hospitalizados durante las temporadas 2017-2018 y 2018-2019, utilizando el registro específico de un hospital terciario. Las complicaciones analizadas fueron: neumonía, fallo multiorgánico, shock séptico, síndrome de distrés respiratorio agudo y eventos cardíacos.Resultados: Un total de 928 adultos con gripe precisaron hospitalización, de los que 303 (32,7%) presentaron una o más complicaciones. El 2,5% de los pacientes sufrieron un evento cardíaco posgripe, con mayor probabilidad de ingreso en la UCI y mayor mortalidad. La vacunación antigripal fue un factor protector del evento cardíaco (OR: 0,32; IC 95%: 0,13-0,83).Conclusiones: La gripe presenta importantes complicaciones en los pacientes hospitalizados. La elevada mortalidad de los eventos cardíacos posinfección implica acentuar las medidas preventivas, destacando la vacunación antigripal anual. (AU)

Background and aims: The aim of this study was to determine the complications of influenza in all adults hospitalized with this disease and, specifically, to analyze the characteristics of post-infection cardiovascular events.Methods: Observational and descriptive study of adults hospitalized with influenza during the 2017-2018 and 2018-2019 seasons using the specific registry of a tertiary hospital. The complications analyzed were pneumonia, multiple organ dysfunction syndrome, septic shock, acute respiratory distress syndrome, and cardiac events.Results: A total of 928 adults with influenza required hospitalization and 303 (32.7%) presented with one or more complications. A post-influenza cardiac event occurred in 2.5% of patients; they had a higher probability of ICU admission and higher mortality. Influenza vaccination was a protective factor for cardiac events (OR 0.32; 95%CI 0.13-0.83).Conclusions: Influenza can lead to important complications in hospitalized patients. The high mortality rate associated with post-infection cardiac events means that preventive measures, including annual influenza vaccination, need to be emphasized. (AU)

[Epidemiological situation of tuberculosis in the province of Salamanca and the influence of HIV/AIDS infection]. / Situación epidemiológica de la tuberculosis en la provincia de Salamanca e influencia de la infección VIH/sida.

This study aimed to determine the real prevalence of tuberculosis and the influence of HIV/AIDS infection from January 1992 to January 2001 in the health area of Salamanca. Data on tuberculosis were obtained from the EDO system of the Medical Records Service and the Microbiology Department of the University Hospital of Salamanca. Data on HIV/AIDS infection were obtained from the records on seropositive patients from the Preventive Medical Service. It was found that during the study period, 769 cases of tuberculosis were diagnosed and 606 cases were reported, 12.7% of which were in HIV/AIDS patients. There was 8.7% resistance to isoniazid and 8.3% to rifampin. Multidrug resistance was found in 4.17%. It was concluded that there is a close relationship between tuberculosis and HIV/AIDS infection, which may constitute a risk factor for the disease as well as for the appearance of multidrug resistance. The low reporting of tuberculosis cases shows the need for active surveillance systems.
