PurposeTo measure surgical site infection (SSI) rates among gastrointestinal surgeries and to identify the associated risk factors.Patients and methodsWe conducted a multicenter, retrospective, surveillance-based study of adults undergoing gastric, colon, and small bowel (SB) procedures from January to December 2016. Univariate and multivariate analyses were conducted to determine the predictive variables in each surgery.ResultsIn total, 71 of 2,099 patients developed SSI – 0.8%, 19.8%, and 10.8% following gastric, colon, and SB surgeries, respectively. In gastric surgery, the risk factors identified by univariate analysis were age, duration, wound class, risk index, emergency, and scope use (P<0.05). Logistic regression analysis revealed that the laparoscopic approach was the only significant predictor, with an inverse relationship of SSI rate vs open gastric surgery (P<0.05). Prolonged duration was a significant risk factor for developing SSI in colon surgery, and emergency was a significant risk for development of SSI in SB surgery. Gram-negative bacilli were the main causative pathogens, with a high percentage of multidrug-resistant organisms.ConclusionVariances in SSI rates and risk factors among gastric, colon, and SB surgery were detected. The use of an endoscope in gastric surgeries exhibited a protective effect against the development of SSI. The reduction of the SSI rate can be achieved by targeted preventive interventions for the identified risk factors.

Purpose The purpose of this paper is to assess the effectiveness of Kuwait Infection Control Directorate educational program in improving knowledge, attitude and practices (KAP) of environmental service workers (ESWs) regarding the management of infectious and sharps waste. Design/methodology/approach An interventional educational pre-test/post-test study was conducted over seven months, on a sample of 102 ESWs in Farwaniya General Government Hospital, Kuwait. Educational sessions and practical training using the KAP approach were applied during the intervention phase. The KAP of the participants were assessed using a questionnaire and observation checklist in the pre- and post-intervention phases. Findings Improvement in all aspects of the KAP regarding infectious and sharps waste management was observed among the participants after implementation of the intervention, with a statistically significant difference between pre- and post-test results (p<0.01). Originality/value The applied multi-component educational program in the current study can be successfully implemented for ESWs in all government hospitals in Kuwait and other countries with similar settings.

Anti-HBs levels wanes with time. Many studies discussed the B cell response to HBV vaccine. However, the data about memory T cell response are limited. To evaluate the efficacy of hepatitis B vaccine via evaluating anti-HBs levels and HBsAg specific memory T-lymphocytes through descriptive study. The study was conducted in a tertiary care setting. This study included 440 vaccinated persons during infancy. Group I: 6 to less than 10 years old; Group II: 10 to less than 14 years old; Group III: 14 to less than 17 years old; Group IV: 17 years old. The serum samples were screened for HBV markers. Cytokines secretion by HBsAg-specific memory CD45RO(+) CD4(+) T cells was measured after in vitro culture using flow cytometry. The mean titer of anti-HBs was higher in group I in comparison to others (P-value = 0.000 for each). IFN-γ and IL-4 secreted by memory CD4(+) T cells were positive in all with anti-HBs>100 mIU/ml, while positive in 87% and 75% of participants with anti-HBs <10 mIU/ml and positive in 73% and 32% of participants with absent anti-HBs. The percentage of cells secreting IFN-γ and those secreting IL-4 were higher among participants with serum anti-HBs >100 mIU/ml than those having <10 mIU/ml or absent (P < 0.001 for each). Anti-HBs positivity decreased with time since childhood vaccination. Breakthrough infections are rare in vaccinated persons. Hepatitis-B vaccine is efficient in controlling HBV infection. Flow cytometry is a useful tool to assess the long term persistence of T cell memory after childhood vaccination. J. Med. Virol. 88:1567-1575, 2016. © 2016 Wiley Periodicals, Inc.

Background: To date, central line-associated bloodstream infections (CLABSIs) are the most common healthcare-associated infections in high-risk neonates and children. These infections are associated with significantly longer hospital stays, increased health care cost, and mortality in the health care systems. Application of evidence-based preventive interventions has proven to decrease CLABSI rate. The purpose of this study is to reduce the undesired relative high CLABSI rate through the adoption of standardized quality improvement interventions. Methods: and Methods: The study employed a pre-post-intervention design. Phase one is a retrospective calculation of 12 months of surveillance period as a baseline. Phase 2 establishes a multidisciplinary quality improvement intervention, which includes the formation of a dedicated central line insertion team, provision of central line kit at the bedside, training and educating the team, and selecting bundle checklist. In the third phase, we performed auditing and calculating the checklist compliance and monthly feedback for 12 consecutive postintervention months. During phase 1 and 3, we calculated the following measures; CLABSI per 1000 catheter-days, duration of central line use, and device utilization ratio. Results: During the post-intervention phase the CLABSI rate significantly reduced by 59.5% from 7.5 to 3.0 per 1000 central line day, and the duration of use of the central line decreased from 21.3 AE 9.9 to 11.0 AE 3.2 days (P < 0.05).

Background: Elizabethkingia meningoseptica is frequently found in hospital environments and usually associated with healthcare-associated infections (HAIs), particularly in patients in the intensive care units (ICU). The current study report an outbreak of E. meningoseptica infection/colonization in the pediatric intensive care unit, highlighted the infection control methods used to stem the spread.Methods: During a period of 7 months, May-November 2015, 4 patients were infected/ colonized by E. meningoseptica. Infection control measures were re-emphasized after each case and environmental swabs were cultured to detect possible source. Follow up for 25 months to ensure eradication of the pathogen.Results: Four patients were colonized/ infected with E. meningoseptica, their mean age 22 months. The average time patients spent in ICU between admission and isolation of E. meningoseptica was 27.5±19.2 days. All patients were mechanically ventilated. 25% E. meningoseptica isolated from blood causing healthcare associated Central Line Associated Blood Stream Infection (CLABSI) while it was isolated from endotracheal tube (ETT) secretion in 75% as healthcare associated colonization. The 4 isolates confirmed as identical using pulsed field gel electrophoresis (PFGE).Conclusions: Intensive infection control measures including healthcare workers education, emphasizing hand hygiene, comprehensive cleaning and disinfection of equipment and the environment are important to eradicate the bacterium.
