Insights
Penicillin-resistant pneumococci (PRP) are a concern in hospitals. White race and pediatric chronic care facility residence were linked to PRP acquisition, highlighting potential reservoirs for transmission.
Area of Science:
- Infectious Diseases
- Clinical Microbiology
- Epidemiology
Background:
- Penicillin-resistant pneumococci (PRP) pose a significant challenge in healthcare settings.
- Understanding risk factors for PRP acquisition is crucial for infection control.
Purpose of the Study:
- To identify risk factors associated with the acquisition of penicillin-resistant pneumococci (PRP) at a New York City university hospital.
- To investigate the prevalence and characteristics of PRP in a pediatric chronic care facility.
Main Methods:
- A case-control study comparing patients with PRP and penicillin-sensitive pneumococcal infections.
- Analysis of demographic data, including race and residence.
- Microbiological investigation of isolates for antibiotic resistance patterns and serotyping.
Main Results:
- In 1994, 21% of Streptococcus pneumoniae infections were caused by PRP.
- White race and residence in a pediatric chronic care facility were significantly associated with penicillin resistance.
- 33% of children in one chronic care facility were colonized with PRP, with many isolates also resistant to ceftriaxone.
- Prior antibiotic use, particularly beta-lactams, correlated with penicillin resistance.
- All typeable PRP isolates belonged to multidrug-resistant serotype 23.
Conclusions:
- Pediatric residents in chronic care facilities may represent a significant reservoir for PRP.
- These facilities could be a source of PRP transmission to acute care hospitals.
- Targeted infection control strategies in chronic care settings are warranted to mitigate PRP spread.
Abstract:
Risk factors for the acquisition of penicillin-resistant pneumococci (PRP) were analyzed at a university hospital in New York City. Patients with PRP and control patients with penicillin-sensitive pneumococcal infections were compared. In 1994, 24 (21%) of 113 patients with Streptococcus pneumoniae infections had PRP; 13 PRP isolates were from children and 11 from adults. Only white race (P < .05) and residence in a pediatric chronic care facility (P < .05) were significantly associated with penicillin resistance. An investigation at one chronic care facility revealed that 33% of children (17/52) had PRP colonization. Fourteen of the 17 PRP isolates were also resistant to ceftriaxone. Prior antibiotic use and specifically beta-lactam use were associated with penicillin resistance. All typeable PRP isolates were multidrug-resistant serotype 23. Pediatric residents in chronic care facilities may be an important reservoir of PRP and may serve as a source of PRP transmission when they are transferred to acute care hospitals.
