Aim: To clarify the utility of sepsis evaluation using the Quick Sequential Organ Failure Assessment (qSOFA) tool in addition to the Pneumonia Severity Index (PSI); age, dehydration, respiration, orientation and blood pressure (A-DROP) index; and immunodeficiency, respiration, orientation, age and dehydration (I-ROAD) scoring systems, and risk factor evaluation of potentially drug-resistant (PDR) pathogens are suggested in the 2017 guidelines for pneumonia of the Japanese Respiratory Society in nursing- and healthcare-associated pneumonia patients., Methods: We included 289 hospitalized nursing- and healthcare-associated pneumonia patients between April 2016 and March 2017, and investigated the ability of PSI, A-DROP, I-ROAD and qSOFA to predict pneumonia-related mortality. We also evaluated the associations among the risk factors for PDR pathogens, the detection ratio of PDR pathogens and pneumonia-related mortality., Results: The mortality rate of pneumonia during hospitalization was 6.9% (20/289). The area under the curve for pneumonia-related mortality predicted using PSI, A-DROP, I-ROAD and qSOFA was 0.697 (95% confidence interval [CI] 0.59-0.80), 0.63 (95% CI 0.51-0.76), 0.61 (95% CI 0.52-0.70) and 0.701 (95% CI 0.59-0.81), respectively. In addition, higher areas under the curve were observed for pneumonia-related mortality predicted according to a combination of PSI and hypoalbuminemia (<2.5 g/dL) (0.75, 95% CI 0.64-0.86), and qSOFA and hypoalbuminemia (0.74, 95% CI 0.62-0.86) than for PSI and qSOFA alone. No significant associations were observed among the risk factors for PDR pathogens, the detection ratios of PDR pathogens and pneumonia-related mortality., Conclusions: qSOFA and the combination of qSOFA and hypoalbuminemia might be simple and useful evaluation tools for predicting pneumonia-related mortality in nursing- and healthcare-associated pneumonia patients.
