Health care-associated measles outbreak in pediatric wards in a tertiary care hospital: Challenges and Swiss cheese model enforcement for patient safety.

INTRODUCTION: Measles is one of the most contagious of all infectious diseases, for example, up to 9 out of 10 susceptible people with close contact to a measles patient will develop measles. In countries where measles is rare, transmissions in health care facilities have been a key factor in amplifying outbreaks OBJECTIVES: Describe the hospital transmission of measles among unvaccinated children in pediatric service, challenges faced and recommendations for health care settings by applying the Swiss cheese model. METHOD: Between December 2019 and January 2020; multiple exposures to measles cases occurred. The incident and factors that led to the outbreak are described. The matrix and fusion genes, non-coding region sequence analysis was also conducted on the 3 strains isolated from the cases. RESULTS: The outbreak extended from December 2019 to January 2020, which resulted in 110 exposed individuals (85 health care workers and 25 patients). Eleven (44%) children exposed were vaccinated, 14 (56%) were not yet vaccinated, and the measles status of 10 (11.8%) HCWs was not known at the time of the outbreak. Two infants acquired measles in the hospital, and both required ICU care. Three infants and one HCW received immunoglobulin. The phylogenetic tree of the matrix and fusion genes, non-coding region sequencing confirmed that all three cases had 100% identical measles strain. CONCLUSIONS: In countries where measles elimination goals are achieved, a multifaceted approach to prevent measles transmission in health care is vital to maintain patient safety.

Rates of catheter-associated urinary tract infection in tertiary care hospitals in 3 Arabian Gulf countries: A 6-year surveillance study.

BACKGROUND: The true burden of catheter-associated urinary tract infections (CAUTIs) remains largely unknown because of a lack of national and regional surveillance reports in Gulf Cooperation Council (GCC) countries. The purpose of this study was to estimate location-specific CAUTI rates in the GCC region and to compare them with published reports from the U.S. National Healthcare Safety Network (NHSN) and the International Nosocomial Infection Control Consortium (INICC). METHODS: CAUTI rates and urinary catheter utilization between 2008 and 2013 were calculated using NHSN methodology pooled from 6 hospitals in 3 GCC countries: Saudi Arabia, Oman, and Bahrain. The standardized infection ratios of the CAUTIs were compared with published reports of the NHSN and INICC. RESULTS: A total of 286 CAUTI events were diagnosed during 6 years of surveillance, covering 89,254 catheter days and 113,807 patient days. The overall CAUTI rate was 3.2 per 1,000 catheter days (95% confidence interval, 2.8-3.6), with an overall urinary catheter utilization of 0.78. The CAUTI rates showed a wide variability between participating hospitals, with approximately 80% reduction during the study. The overall compliance with the urinary catheter bundle implementation during the second half of the study was 65%. The risk of CAUTI in GCC hospitals was 35% higher than the NHSN hospitals, but 37% lower than the INICC hospitals. CONCLUSIONS: CAUTI rates pooled from a sample of GCC hospitals are quite different from rates in both developing and developed countries.
