Aspiration pneumonia (AP) that develops during hospitalization causes an increase in the need for additional medical resources. However, information about these resources is not sufficient as limited studies have estimated them quantitatively. Against this background, the present study aimed to quantify additional medical resources used for AP developing during hospitalization.
We analyzed DPC data directly obtained from the investigated facilities. Patients who had developed AP while being hospitalized were matched with control subjects by disease, type of surgery, and patient attributes. Based on the differences in average values shown by these 2 groups, we estimated the hospitalization period and quantified additional medical resources used.
As a result, the average period of hospitalization due to AP developing after admission was 17.2 days (11.6 to 22.8 days) [95% CI]. In addition, the average cost of hospitalization due to AP was 619,000 yen (397,000 to 842,000 yen) [95% CI].
In the present study, we quantified additional medical resources used for AP developing after admission. The study results could be widely used as basic material for medical management supporting the prevention of AP during hospitalization.
