Bacteriological testing and recurrence prevention efforts in the diagnosis and treatment of nursing- and healthcare-associated pneumonia and aspiration pneumonia: A questionnaire survey of hospitals across Japan.

Background: Clinical practice guidelines for nursing- and healthcare-associated pneumonia (NHCAP) were developed for pneumonia caused by drug-resistant bacteria and pneumonia in elderly patients, particularly aspiration pneumonia. The identification of pathogenic bacteria and implementation of efforts to prevent the recurrence of aspiration pneumonia are very important in clinical practice. This study examined the extent to which clinicians have established bacteriological testing and recurrence prevention efforts for NHCAP and aspiration pneumonia.
Methods: Questionnaire surveys were mailed to the heads of internal medicine and respiratory medicine departments at 2490 Japanese hospitals. The questionnaire evaluated bacteriological testing for NHCAP or aspiration pneumonia and prevention of the recurrence of aspiration pneumonia.
Results: A total of 350 hospitals responded. These hospitals were grouped on the basis of whether a pulmonologist provided medical care for aspiration pneumonia and whether the hospital employed an infectious disease specialist. For hospitals in which pulmonologists treated aspiration pneumonia, the response rates for "is done in nearly all cases" were 70.0%, 84.7%, 31.6%, and 48.9% for sputum gram staining, sputum culture tests, blood culture tests, and pneumococcal vaccination, respectively. In hospitals that employed an infectious disease specialist, the response rates for "is done in nearly all cases" were 72.8% and 41.3% for sputum gram staining and blood culture tests, respectively. Recurrence prevention for aspiration pneumonia (other than pneumococcal vaccination) was not actively implemented.
Conclusions: Sputum gram staining, sputum culture tests, and other bacteriological tests were implemented quite actively. However, physicians who treat aspiration pneumonia should implement efforts to prevent pneumonia recurrence more actively.
