The pandemic of SARSCov2 infection has created a challenge in health services worldwide. Some scales have been applied to evaluate the risk of intubation, such as the ROX and HACOR. The objective of this study is to compare the predictive capacity of the HACOR scale and the ROX index and define the optimal cut-off points. Study of diagnostic tests based on a retrospective cohort. Composite outcome was the proportion of patients that needed endotracheal intubation (ETI) or died of COVID19 pneumonia. Discrimination capacity was compared by the area under the curve of each of the two scales and the optimal cut-off point was determined using the Liu method. 245 patients were included, of which 140 (57%) required ETI and 152 (62%) had the composite end result of high-flow nasal cannula (HFNC) failure. The discrimination capacity was similar for the two scales with an area under receiver operating characteristic curve of 0.71 and 0.72 for the HACOR scale for the ROX index, respectively. The optimal cut-off point for the ROX index was 5.6 (sensitivity 62% specificity 65%), while the optimal cut-off point for the HACOR scale was 5.5 (sensitivity 66% specificity 65%). The HACOR scale and the ROX index have a moderate predictive capacity to predict failures to the HFNC strategy. They can be used in conjunction with other clinical variables to define which patients may require invasive mechanical ventilation.
Purpose
The purpose of this paper is to systematize the strategic capabilities of seven surviving industrial Catalan companies which were going through explosive growth in 1999.
Design/methodology
We use the comparative case studies method to draw on the common features among the seven in‐debt cases we built. We are well aware that the method of comparative case studies does not provide a sufficient base for bold generalizations. However, the qualitative approach adopted here allows for the first in‐depth look at the strategies that bring surviving entrepreneurs from explosive growth to a more balanced growth path.
Findings
We identify four organizational capabilities as key to the survival of these businesses ten years later: first, ability to prioritize product and market development, including internationalization, over operations; second, ability to reorganize internally and delegate in a timely manner; third, ability to manage innovation and support creativity linked to productivity; and finally, ability to manage economic and financial resources.
Social implications
Implications for the culturally proximate and less‐studied Latin‐American gazelles are presented.
