[Prevalence of SARS-CoV-2 coronavirus infection in patients and professional staff at a medium or long-stay hospital in Spain].

Background And Goals: The aim of the study is to know the prevalence of SARS-CoV-2 infection in patients and professional staff of a medium or long-stay hospital during the peak period of the pandemic in Spain, spring 2020.

Material And Methods: At the end of February 2020, we developed at the hospital a strategy to diagnose the SARS-CoV-2 infection consisting of complementing the realization of PCR tests at real time with a quick technique of lateral flow immunochromatography to detect IgG and IgM antibodies against the virus. We also developed a protocol to realize those diagnostic tests and considered an infection (current or past) a positive result in any of the above tests.

Excessive polypharmacy and survival in polypathological patients.

Purpose: The purpose of this study was to determine whether excessive polypharmacy is associated with a higher survival rate in polypathological patients.

Patients And Methods: An observational, prospective, and multicenter study was carried out on those polypathological patients admitted to the internal medicine and acute geriatrics departments between March 1 and June 30, 2011. For each patient, data concerning age, sex, comorbidity, Barthel and Lawton-Brody indexes, Pfeiffer's questionnaire, socio-familial Gijon scale, delirium, number of drugs, and number of admissions during the previous year were gathered, and the PROFUND index was calculated.
