Gram-Negative Bloodstream Infections in Healthcare: The Relationship Between Antibiotic Resistance, Mortality, and Novel Serological Biomarker.

BACKGROUND: Bloodstream infections caused by Gram-negative bacteria are highly mortal. In this study, we aimed to investigate the relationship between antimicrobial resistance profile and novel serological biomarkers and mortality in bloodstream infections (BSIs) caused by Gram-negative bacteria in intensive care units (ICUs). METHODS: 366 Patients diagnosed with healthcare-associated Gram-negative bloodstream infection in the ICUs of our hospital between February 2015 and December 2021 were included in the study. Demographic variables (age, gender, comorbidities), causative microorganisms and antimicrobial susceptibilities, time to first positive blood culture after hospitalization, length of stay in hospital, surgical procedures, laboratory data (hemograms, C-reactive protein (CRP) levels, albumin), and survival data were collected. Novel serological biomarkers were calculated. RESULTS: Mortality in Gram-negative bloodstream infection was found to be associated with age and novel serological biomarkers, but not with carbapenems and colistin minimum inhibitory concentration (MIC) values. Mortality rates increased with age (p˂0.001). Patients who died had higher C-reactive protein/albumin ratio (CAR) (p<0.001) and neutrophil/lymphocyte ratio (NLR) (p=0.009) and lower prognostic nutritional index (PNI) (p<0.001). CONCLUSION: The study emphasizes that resistance to colistin and carbapenems is not associated with mortality in BSIs caused by Gram-negative bacteria. Novel serological biomarkers may be useful in predicting mortality. These results support the need for further studies to elucidate the true impact of infections caused by resistant bacteria.

Rates of underreported needlestick and sharps injuries among healthcare workers in Turkey: in the light of Infection Control Committee data.

OBJECTIVE: Doctors and nurses are frequently exposed to needlestick and sharps injuries (NSIs) because of their work. It is estimated that NSIs are more common than the rates reported to Infection Control Committee. The purpose of this study was to determine the incidence and reporting rates of NSIs in our hospital. METHODS: After their consent forms were obtained for the questionnaire, 670 doctors and nurses were interviewed face-to-face by the Infection Control Committee nurse. The questionnaire consisted of 22 questions, and the answers were recorded. The questions were on demographic data and injuries. The data of NSIs, whose active surveillance was made in our hospital since 2005 and in the last 1 year, were also analyzed retrospectively. RESULTS: A total of 119 (17%) people out of 670 people who participated in the study had at least one NSI; 43 (36%) people of the 119 people were doctors and 76 (63.9%) people were nurses. The most common injuries among doctors were found in assistant doctors (60%). No statistically significant differences were detected between the doctors and nurses in terms of injury status (P = 0.398). The most common injuries were found in surgical clinics, and a significant difference was detected here when compared to other clinics. The data that 20 (17%) people of the 118 people who were injured by the NSIs reported the injury were obtained from the Infection Control Committee database. CONCLUSION: It is seen that injuries are high in surgical clinics and assistant doctors who have high work stress and workload. There were more injuries with sharp objects than the expected rates in our hospital although the reports were made very rarely. First of all, we should determine strategies, especially education, to reduce injuries, and then remove the obstacles to unreported injuries. The methods of clinics with a high rates of reporting needlestick and sharps injuries to the infection control committee should be examined and tried to be applied in our own clinics.

Retrospective investigation of 9 years of data on needlestick and sharps injuries: Effect of a hospital infection control committee.

BACKGROUND: The risk of occupational transmission of bloodborne pathogens to health care workers is primarily associated with needlestick and sharps injuries (NSIs). However, most NSIs are not reported, and most health care workers are not aware of postexposure procedures. METHODS: Data for NSIs reported in our hospital between 2008 and 2016 were reviewed retrospectively. RESULTS: A total of 546 staff members reported NSIs. Of these, 376 (68.9%) were women. NSIs were more commonly reported by trainee nurses (243 [44.5%]), followed by nurses (121 [22.2%]), cleaning staff (108 [19.8%]), and doctors (49 [9%]). The rate of postexposure interventions was 13% in 2008 and 92.6% in 2016 (P < .0001; χ2 = 82.866). NSI rates also show that the number of applications with NSIs increased over the years. When occupational blood exposure was examined, the number of bloodborne pathogens was 50 (9.3%) cases of hepatitis B virus, 30 (5.6%) cases of hepatitis C virus, 3 cases of Crimean-Congo hemorrhagic fever, 1 case of HIV, and 2 cases of hepatitis B virus and hepatitis C virus coinfection. DISCUSSION: Over the years, the increase in both the appropriate intervention rate and the number of reports to the hospital infection control committee after NSIs shows that regular training regarding NSIs is effective. CONCLUSIONS: Hospital infection control committees may play a more active role in raising awareness in this regard and thus reducing the rate of unreported NSIs.
