ABSTRACT
BACKGROUND: Hand hygiene (HH) is single most effective preventive measure for health care-associated infection, but compliance rates remain low. This study estimated HH compliance among health care workers (HCWs) and examined factors associated with noncompliance. METHODS: An observational study design was carried out in 5 intensive care units (ICUs) at the University Hospital in Riyadh, Saudi Arabia. Among 242 HCWs, a total of 3,940 HH opportunities were observed by 6 trained medical interns and students. The World Health Organization's "Five Moments for Hand Hygiene" procedure was used as a basis for the observations. RESULTS: The overall observed noncompliance rate was 58%. The factors associated with noncompliance were HCW job title (physicians, odds ratio [OR], 2.8; 95% confidence interval [CI], 1.8-4.2; allied health professionals, OR, 2.9, 95% CI, 1.9-4.6); working the a.m. shift (OR, 1.5; 95% CI, 1.3-1.8), working in a pediatric ICU (OR, 1.8; 95% CI, 1.5-2.2), and performance of HH before patient contact (OR, 4.5; 95% CI, 2.6-7.8). CONCLUSIONS: Overall HH noncompliance was high in ICUs of this hospital. The demanding ICU work setting was an important factor associated with noncompliance. HH compliance was highest among therapists and technicians because of fewer patient interactions and thus fewer HH noncompliance opportunities per person. Further studies on the relationship between work environment demands and HH compliance rates are needed.

BACKGROUND: Infection due to community-acquired strains of methicillin-resistant Staphylococcus aureus (CA-MRSA) has been reported with increasing frequency. Herein is described the nosocomial transmission of CA-MRSA involving 13 neonates and two mothers in a well-infant nursery in a teaching hospital in Saudi Arabia. METHODS: From October to November 2009, temporally related cases of CA-MRSA skin and soft-tissue infection occurred in newborns shortly after discharge from a well-infant nursery. An outbreak investigation including case identification, review of medical records, staff screening, environmental cultures, pulsed-field gel electrophoresis, and a case-control study were conducted. Controls were selected from among asymptomatic neonates admitted to the same nursery and matched for the day of admission. RESULTS: Fifteen subjects were found to be CA-MRSA positive: 13 neonates and two mothers. The crude attack rate among neonates was 5.5% during the outbreak period. All 13 neonates presented with skin and soft-tissue infection; one of the mothers had mastitis and a breast abscess. The source of the outbreak was not evident. Pulsed-field gel electrophoresis showed that all of the tested isolates from one strain except one, all contained the staphylococcal cassette chromosome mec (SCCmec) type IV. CONCLUSION: MRSA strains that initially emerged in the community are now causing disease in health-care settings. Adherence to standard infection control practices, including consistent hand hygiene, in newborn nurseries is important to prevent transmission in such settings.
