    Introduction: Studies indicate that adherence to hand hygiene guidelines is at suboptimal levels. We aimed to explore the reasons for poor hand hygiene compliance. Methodology: A qualitative study based on the Theory of Planned Behavior as a framework in explaining compliance, consisting four focus group discussions and six in-depth interviews. Results: Participants mostly practiced hand hygiene depending on the sense of dirtiness and cleanliness. Some of the participants indicated that on-job training delivered by the infection control team changed their perception of emotionally based hand hygiene to indication based. Direct observations and individual feedback on one-to-one basis were the core of this training. There was low social cohesiveness and a deep polarization between the professional groups that led one group accusing the other for not being compliant. Conclusions: The infection control team should continue delivering one-to-one trainings based on observation and immediate feedback. But there is need to base this training model on a structured behavioral modification program and test its efficacy through a quasi-experimental design. Increasing social cohesiveness and transforming the blaming culture to a collaborative safety culture is also crucial to improve compliance. High workload, problems related to work-flow and turnover should be addressed.

    Hand hygiene knowledge, perception and practice of healthcare workers in a Turkish university hospital intensive care unit
    (J INFECTION DEVELOPING COUNTRIES, 2019-08-31) BİLGİN, HÜSEYİN; Sili, Uluhan; Ay, Pinar; Bilgin, Huseyin; Hidiroglu, Seyhan; Korten, Volkan
    Introduction: While improvement of hand hygiene (HH) compliance is considered as the best approach to reduce healthcare-associated infections, the instructional interventions in HH among healthcare workers of intensive care unit (ICU) of our hospital was not successful enough. The following study was conducted to evaluate HH knowledge, perception, practice and effectiveness of the trainings among healthcare workers of ICU in our hospital. Methodology: A cross-sectional study was conducted in the ICU containing 8 medical and 16 surgical beds with 284 filled questionnaires about HH knowledge and 1187 observed opportunities for HH compliance. Results: Overall observed HH compliance rate was 40.6%; lowest compliance was 21.7% for before clean/aseptic procedure indication and highest compliance was 68.6% for after touching a patient indication. Although > 90% healthcare workers correctly identified the World Health Organization's five indications for HH, 82 -85% failed to recognize non-indications, i.e. when it was not necessary to perform HH. Our study showed that 15.1% of healthcare workers neither received nor felt the need for HH training. Conclusions: Despite regular HH trainings, healthcare workers could not differentiate when HH was not required which suggested failure to understand HH rationale. This may explain poor HH compliance rates. A systematic study is needed in order to find out the reasons behind of this noncompliance and improve HH training methods for educating healthcare workers.

    Colistin nephrotoxicity in critically ill patients after implementation of a new dosing strategy
    (J INFECTION DEVELOPING COUNTRIES, 2019-10-31) KORTEN, VOLKAN; Ozel, Ayse Serra; Ergonul, Onder; Korten, Volkan
    Introduction: Intravenous colistin is increasingly used to treat multidrug-resistant Gram-negative infections. Highly variable nephrotoxicity rates have been reported. Recent PK/PD studies propose a loading dose and a maintenance dose for better efficacy, but data on the renal toxicity of such regimens are rare. This study aimed to evaluate the incidence and risk factors for nephrotoxicity related to colistin after implementation of a new dosing regimen including a loading dose. Methodology: This was a prospective observational study that was made between adult patients who received a minimum of 48 hours of intravenous colistin from December 2012 to January 2014 at the medical and surgical intensive care units (ICU) of a university hospital. The severity of acute kidney injury (AKI) was defined by the RIFLE criteria. Results: Fifty-nine patients met the inclusion criteria, and 31 (52.5%) developed nephrotoxicity. The APACHE-II score was > 15 in 81% of patients. The median time to nephrotoxicity was 7 days. Patients with AKI were in risk (10.2%), injury (16.9%), failure (25.4%), and none of the patients developed permanent renal insufficiency. A logistic regression model identified three predictors of colistin-associated nephrotoxicity: age; the number of days that estimated target plasma concentrations of colistin were >= 3.5 mg/L in the first week of therapy; and baseline creatinine level. Conclusion: In this cohort of severely ill ICU patients, colistin led to a relatively high rate of nephrotoxicity. Further studies are needed to identify the optimal dose for both efficacy and safety.
