Model of Park et al for Identifying a Patient with Healthcare-Associated Pneumonia with an Antibiotic-Resistant Pathogen

Description

Park et al developed a score for identifying a patient with healthcare-associated pneumonia due to an antibiotic-resistant pathogen. This can help to guide appropriate antibiotic therapy. The authors are from Severance Hospital and Yonsei University in Seoul, Republic of Korea.

Patient selection: hospitalized patient with healthcare-associated pneumonia

Parameters:

(1) nasogastric tube feeding

(2) hospitalization within 90 days before the diagnosis of pneumonia

(3) intravenous antibiotic therapy within 30 days before the diagnosis of pneumonia

(4) admission from long-term nursing home (NH) or extended care facility (ECF)

(5) chemotherapy within 30 days before the diagnosis of pneumonia

(6) wound care within 30 days before the diagnosis of pneumonia

(7) chronic dialysis

Parameter	Finding	Points
nasogastric tube feeding	No	0
	Yes	5
recent hospitalization	No	0
	yes	3
recent IV antibiotic therapy	No	0
	yes	2
admission from NH or ECF	No	0
	yes	1
recent chemotherapy	No	0
	yes	1
recent wound care	No	0
	yes	1
chronic dialysis	No	0
	yes	1

total score =

= SUM(points for all 7 parameters)

Interpretation:

• minimum score: 0

• maximum score: 14

• The higher the score the greater the risk for a drug-resistant organism.

Total Score	Percent Resistance
0 to 2	21%
3 to 5	45%
6 to 14	68%

Performance:

• The area under the ROC curve was 0.72.
