Georgia Prison 2 Initial Interventions
“Appropriate” laundering Improved access to wound care Increased access to soap Offender education
Later Interventions Cohorting of infected offenders 5-day course of chlorhexidine soap for all offenders
No sustained response to interventions seen

Mississippi Prison Risk Factors (multivariate analysis)
Sharing pillows or bed sheets (AOR = 40.6) Touching another offender’s boil (AOR =
21.4) Beta-lactam prescription within 1-12 months
(AOR = 5.7) Using state-issued soap (AOR = 5.0) Self-reported insect bites (AOR = 4.2)
AOR = adjusted odds ratio

Mississippi Prison Nasal Colonization with MRSA
Female - 5.9%, Male - 2.5% Risk factors for colonization (multivariate)
Housed in disability section Picking/popping furuncles Doctor visit in past year Longer incarceration

Mississippi Prison Interventions
Improved surveillance Optimized antibiotic recommendations Reinforcing infection control practices in
clinics Offender education Use of antimicrobial soap

Georgia jail 2,800 beds, average stay 25 days Rate
13.7 infections/1,000 offender-years initially 84.3/1,000 offender-years with case finding
Inappropriate antibiotic use (beta-lactams) noted, even when MRSA cultured
Interventions Screening for skin infection Standardized treatment regimens Hygiene education for offenders Changes in laundry practice

Medical Risk Factors in TDCJ Overall risk for MRSA was 12 initial
infections/1,000 offender-years No association found with skin disease Medical Alert Codes may be inaccurate Cannot r/o associations being a surrogate
for frequent medical encounter 84% of infections not associated with any
of the medical risk factors listed

MRSA (and MSSA) Control in TDCJ Treat dermatitis promptly and aggressively Stress good hygiene with staff and
offenders Culture draining lesions - diagnose early Treat appropriately Cover draining lesions or single-cell
Do not routinely isolate

What Hasn’t Worked Decolonization after first infection Cohorting Chlorhexidine for cohorted offenders Frequent (TID) disinfection of common
areas Not clear whether the intervention was
ineffective or the implementation was inadequate
