Central-Line-Associated Bloodstream Infections (CLABSIs) Incidence and the Role of Obesity: A Prospective, Observational Study in Greece.

INTRODUCTION: Although central venous catheters (CVCs) provide reliable vascular access, there are several risks linked with their use, with the rates of central-line-associated bloodstream infections (CLABSIs) being the most important ones. CLABSIs have a big impact on mortality rates and health care costs. The aim of this study was to investigate the incidence of obesity in the development of central venous catheter infections. MATERIAL AND METHOD: This is a prospective, observational study. The data were collected in the ICUs of three major hospitals in Greece, over a period of 18 months. Totally, 744 patients were included in the study. RESULTS: The study included 744 ICU patients aged 63.6 ± 16.6 years. The Apache II score and MODS score of patients were 23.3 ± 6.9 and 7.5 ± 3.8, respectively. Totally, 5.426 catheter-days were included in the study. Among the 722 CVCs, 178 (24.7%) were CLABSIs. The incidence rate of CVC-associated CLABSI was 22.48 infections per 1000 catheter-days. CLABSI was significantly predicted by the BMI (p = 0.001), by the diabetes mellitus as comorbidity (p = 0.013), by the doctors' experience (p = 0.001), by the type of CVC (p = 0.001) and CVC site (p = 0.001), by the number of efforts for CVC insertion (p = 0.009), by the catheterization's duration (p = 0.001) and by the MODS score (p = 0.001). CONCLUSIONS: Better staff training focused on care bundles preventing infections, better medical training focused on less efforts for CVC insertion, and the use of Ultrasounds during the CVC insertion may be the main factors that can lead to lower CLABSI rates in obese patients. Further research relating CLABSI rates in ICU patients and obesity is needed.

Light affects heart rate's 24-h rhythmicity in intensive care unit patients: an observational study.

BACKGROUND: Intensive care unit (ICU) patients experience two affronts to normal 24-h rhythms: largely internal events such as medication and external factors such as light, noise and nursing interventions. AIMS AND OBJECTIVES: We investigated the impact of light variance within an ICU on 24-h rhythmicity of three key physiological parameters: heart rate (HR), mean arterial blood pressure (MAP) and body temperature (BT) in this patient population. DESIGN: Patients were assigned to beds either in the 'light' or 'dark' side within a single ICU. An actigraph continuously recorded light intensity for a 24-72-h period. METHODS: Measurements of HR, MAP and BT were recorded every 30 min. RESULTS: HR, MAP and BT did not follow 24-h rhythmicity in all patients. Higher light exposure in the Light Side of the ICU (122·3 versus 50·6 lx) was related to higher HR (89·4 versus 79·8 bpm), which may translate to clinically relevant outcomes in a larger sample. Duration of stay, the one clinical outcome measured in this study, showed no significant variation between the groups (p = 0·147). CONCLUSIONS: ICU patients are exposed to varying light intensities depending on bed positioning relative to natural sunlight, affecting the 24-h rhythm of HR. Larger, well-controlled studies also investigating the effect of relevant light intensity are indicated. RELEVANCE TO CLINICAL PRACTICE: Light is a variable that can be manipulated in the constrained environment of an ICU, thus offering an avenue for relatively unobtrusive interventions.

Parental Health Literacy in the Pediatric Surgical Setting.

Health literacy (HL) in the pediatric setting has been associated with poor health outcomes and plays an important role in the existing health disparities. Low parents caregivers HL influences health outcomes mainly in chronically ill children. Trying to identify the role of HL in the pediatric surgical and dentistry setting, we conducted a review of the relevant literature. The paucity of studies and the heterogeneity of the methodology do not lead to specific results. The need for more and larger studies in the field is evident and crucial in order to ameliorate the quality of surgical care in pediatric patients.

Effects of a Personalized Nurse-Led Educational Program for New Patients Receiving Oral Anticoagulant Therapy after Mechanical Heart Valve Prosthesis Implantation on Adherence to Treatment.

BACKGROUND: Life-long anticoagulant therapy is mandatory for patients who undergo heart valve replacement with implantation of a mechanical prosthesis. The aim of this study was to investigate the effects of a nurse-led patient educational program concerning oral anticoagulant therapy intake after heart valve replacement surgery on patients' knowledge of important parameters of anticoagulant administration. METHODS: In this single-center study, 200 patients who underwent surgical implantation of a mechanical prosthesis were divided into 2 groups. The control group received the basic education concerning oral anticoagulants, while the intervention group received a personalized educational program. RESULTS: Personalized education was correlated with a better regulation of therapeutic international normalized ratio (INR) levels and adequate knowledge among patients. Therapeutic levels of INR were achieved in 45% of the patients during the first month, 71% in the third month, and 89% in the sixth month after discharge in the intervention group, compared to 25%, 47%, and 76% in the control group, respectively. Patients' satisfaction with the information was higher in the intervention group than in the control group. The percentage of satisfaction reached 80% for the intervention group versus 37% for the patients of the control group. CONCLUSION: The implementation of the nurse-led educational programs was associated with improved clinical results and increased adherence to oral anticoagulant treatment.

Parental anxiety in pediatric surgery consultations: the role of health literacy and need for information.

INTRODUCTION: Although important, parental anxiety, health literacy and need-for-information in pediatric surgery outpatient clinics have not been extensively studied. Lower educational attainments, minorities and lower socioeconomic status have been associated with limited health literacy. Parental anxiety has been related to health literacy, sex, education and information needs. The aim of this study is to investigate health literacy and need-for-information and their association to parental anxiety in consultations of pediatric surgery. MATERIALS & METHODS: We conducted an observational, cross-sectional study in the outpatient pediatric surgery clinic from December 2016 to October 2017. Health literacy, anxiety and need-for-information of parents/guardians of children waiting for pediatric surgical consultation were evaluated. Multivariate regression analysis was used to examine the impact of health literacy and need-for-information on parental/guardian anxiety considering sociodemographic and clinical characteristics of the participants. RESULTS: Almost half (46.1%) of the 664 parents/guardians recruited had limited or problematic health literacy and 79.8% of the sample was classified as being anxious. Parental/guardian anxiety was associated at the multiple regression analysis with parental health literacy level (ß = -0.282, p < 0.001), need-for-information preoperatively (ß = 0.907, p < 0.001), educational level (ß = -0.716, p = 0.001), sex (ß = 1.563, p < 0.001), and severity of the condition of the child (ß = 0.379, p < 0.001). CONCLUSION: Parents/guardians experience high levels of anxiety, which is associated to health literacy and need-for-information. These factors should be considered in pediatric surgical consultations, aiming to reduce parental anxiety. TYPE OF STUDY: Retrospective Study. LEVEL OF EVIDENCE: Level II.

Perioperative inadvertent hypothermia among urology patients who underwent transurethral resection with either TURis or transurethral resection of the prostate method.

PURPOSE: The purpose of the study was to investigate the incidence of perioperative hypothermia in urology patients undergoing transurethral resection with either TURis or transurethral resection of the prostate method and to recognize the risk factors that were responsible for the occurrence of hypothermia intraoperatively in these patients. METHODS: It was a randomized prospective study. A total of 168 patients, according to American Society of Anesthesiologists physical status I-III, were scheduled for transurethral resection either with TURis or transurethral resection of the prostate method. We measured the core body temperature before (preoperative), during (perioperative) and after (postoperative) the surgery. Age, body mass index, American Society of Anesthesiologists score, duration of surgery, preoperative prostatic volume, and vital signs were also recorded. RESULTS: The prevalence of inadvertent hypothermia was 64.1% for the TURis group and 60% for the transurethral resection of the prostate group. Hypothermic patients in TURis group were significantly older (87.7 ± 1.7 vs 68 ± 6.7 years, p < 0.05) and had lower body mass index (26.9 ± 3.6 vs 29.2 ± 2.7, p < 0.05), while hypothermic patients in the transurethral resection of the prostate group were significantly older (86 ± 1.1 vs 70 ± 7.4 years, p < 0.05) and had notably higher duration of surgery (140.6 ± 28.9 vs 120.3 ± 14.3 min, p < 0.05) than normothermic patients. CONCLUSION: Perioperative inadvertent hypothermia among urology patients who underwent transurethral resection with both TURis and transurethral resection of the prostate method is of high incidence. We recommend monitoring of the temperature of core body of all these patients, especially those with advanced age and lower body mass index.

Ad libitum and restricted day and night sleep architecture.

This study represents a first controlled comparison of restricted versus unrestricted sleep in both day and night sleep categories. A repeated measures study of a homogenous group of young women without sleep disorders (n=14) found that stage 1, 2, 3 and REM sleep, as well as sleep latency were not statistically different between day ad libitum sleep (DAL) and day interrupted (DI) sleep categories, while night interrupted (NI) and ad libitum (NAL) sleep showed strikingly different architecture.
