Assessment of Emergency Department Key Performance Indicators about Surge Response Actions Across Three Periods of the COVID-19 pandemic in an Italian Hospital

Abstract

Introduction:At the beginning of the COVID-19 pandemic, Italian emergency departments (EDs) had to hastily implement current surge response plans or create new ones. The objectives of this study are to quantitatively assess ED performance improvements between selected non-pandemic and pandemic periods at Sant’Anna hospital in Como, Italy, and to relate these to adopted and adapted surge response actions.Method:The average length of stay (LOS), time-to-physician initial assessment (TPIA) and left-without-being seen (LWBS) rates were calculated during two ED periods prior to the pandemic and then three periods during the pandemic in the COVID ED (C-ED) dedicated to treat COVID patients, and the COVID-free ED (NC-ED) dedicated to treat all other patients. Then quantitative data analysis based on hypothesis testing was performed.A qualitative theme and subtheme data analysis based on the Hospital Surge Preparedness and Response Index (HSPRI) was performed on baseline strategies before each pandemic period and on the actions implemented in the subsequent period.Results:The LOS increased across all periods, while the TPIA decreased in the first two pandemic periods in comparison to pre-pandemic periods. The NC-ED LOS was lower than the C-ED LOS, and the C-ED TPIA was lower than the NC-ED TPIA in all three pandemic periods. The LWBS decreased between pre-pandemic and pandemic periods, with an increasing trend towards pre-pandemic levels in the last pandemic period. Of the 20 action items listed in the HSPRI, six were implemented in the first pandemic period, eight in the second and one in the third.Conclusion:The LOS, TPIA and LWBS rates are useful indicators to rapidly obtain an overview of ED performance but failed to provide an exhaustive assessment because ED performance depends on countless external and internal variables. Close collaboration of ED leaders with other healthcare agencies is critical to respond to a pandemic surge.
