drip_pneumonia_score: Drug Resistance in Pneumonia (DRIP) Score

Description

Calculates the DRIP Score to predict the risk of drug-resistant pathogens in patients with community-acquired pneumonia (CAP). This tool helps guide empiric antibiotic selection, potentially reducing the unnecessary use of broad-spectrum agents (like vancomycin or piperacillin-tazobactam) in low-risk patients.

Usage

drip_pneumonia_score(antibiotic_use_60d, long_term_care, tube_feeding,
                     prior_drug_resistant_organism_1yr, hospitalization_60d,
                     chronic_pulmonary_disease, poor_functional_status,
                     acid_suppression_14d, wound_care, mrsa_colonization_1yr)

Value

A list containing:

DRIP_Score

The calculated total score (Range 0-14).

Risk_Level

"Low Risk" (<4) or "High Risk" (>=4).

Recommendation

Antibiotic stewardship guidance.

Arguments

antibiotic_use_60d

Numeric (0 or 1). Antibiotic use within the past 60 days. (1 = Yes, +2 points).

long_term_care

Numeric (0 or 1). Resident of a long-term care facility (nursing home, skilled nursing, rehab; excludes assisted living/group homes). (1 = Yes, +2 points).

tube_feeding

Numeric (0 or 1). Presence of tube feeding (NG, NJ, or PEG). (1 = Yes, +2 points).

prior_drug_resistant_organism_1yr

chronic_pulmonary_disease

Numeric (0 or 1). History of chronic pulmonary disease (COPD, Asthma, ILD, etc.). (1 = Yes, +1 point).

poor_functional_status

Numeric (0 or 1). Poor functional status (Karnofsky < 70 or non-ambulatory). (1 = Yes, +1 point).

Numeric (0 or 1). Use of gastric acid suppression (PPI or H2 blocker) within the past 14 days. (1 = Yes, +1 point).

wound_care

Numeric (0 or 1). Active wound care at the time of admission. (1 = Yes, +1 point).

mrsa_colonization_1yr

Numeric (0 or 1). Documented MRSA colonization within the past year. (1 = Yes, +1 point).
