Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Lymphoma Presenting as Peritoneal Lymphomatosis with Ascites

Multiple intra-abdominal organ infiltration or disseminated peritoneal lymphoma receives much less attention than peritoneal carcinomatosis in clinical practice. This may be due to its relatively infrequent occurrence. In this report, an 89-year-old woman was diagnosed with disseminated peritoneal lymphoma with gastric and rectal involvement and marked ascites. Flow cytometry of the surface markers for ascites showed positive results for CD19, CD20 and CD45. Biopsy of the stomach and rectum were all reported to show diffuse large B-cell lymphoma. The cytology of ascites is a simple and effective method for making a diagnosis from adequate samples with time limitations. The management of this disease depends on the individual case. It must be kept in mind that differential diagnosis from other pathologic entities with similar imaging features or high ascitic fluid adenosine deaminase levels is difficult because of considerable overlap of clinical features. To prolong the survival of patients with peritoneal lymphomatosis, diagnosis should be made as early as possible

Effect of frailty, physical performance, and chronic kidney disease on mortality in older patients with diabetes : a retrospective longitudinal cohort study

Abstract Background Declined renal function is associated with physical function impairment and frailty in a graded fashion. This study aimed to examine the relationship between renal function, frailty and physical performance with mortality in older patients with diabetes, while also determining their combined effects on patient outcome. Methods A retrospective longitudinal study was conducted in elderly patients with diabetes. Kidney disease staging was based on clinical practice guidelines of the International Society of Nephrology, and chronic kiney disease (CKD) was defined as urinary albumin to creatinine ratio (UACR) > 30 mg/g, persistent reduction in estimated glomerular filtration rate (eGFR) below 60 mL/min per 1.73 m2 or both. The modified Rockwood frailty index (RFI) was composed of cumulative health deficits, and physical function was determined by handgrip strength (HGS). Additionally, a timed up and go (TUG) test was assessed at baseline. Kaplan-Meier survival and Cox proportional hazard analyses were used to analyze the association between CKD, frailty, physical function and mortality. Results For the 921 enrolled patients, their mean age was 82.0 ± 6.7 years. After a median 2.92 (interquartile range [IQR] 1.06–4.43) year follow-up, the survival rate was 67.6% and 85.5% in patients with and without CKD, respectively. The mortality hazard ratio (crude HR) with CKD was 5.92 for those with an RFI higher than 0.313 (95% CI 3.44–10.18), 2.50 for a TUG time longer than 21 s (95% CI 1.22–5.13), and 2.67 for an HGS lower than 10.57 kg in females or 20.4 kg in males (95% CI 1.12–6.37). After multivariate adjustment, the mortality hazard ratio for an RFI ≥ 0.313 was 5.34 (95% CI 2.23–12.80) in CKD patients, but not in patients without CKD. In subgroup analysis, patients experiencing CKD and frailty, or physical function impairment, had the lowest survival proportion followed by only frailty/declined physical function, only CKD, without CKD, and non-frailty/non-physical impairment. Conclusion CKD, frailty and physical function impairment were all associated with an increased mortality risk in older patients with diabetes, while the combined effects of these 3 factors were seen on patient outcome

Optimization of the Cathode Arc Plasma Deposition Processing Parameters of ZnO Film Using the Grey-Relational Taguchi Method

We deposited undoped ZnO films on the glass substrate at a low temperature (<70°C) using cathode arc plasma deposition (CAPD) and the grey-relational Taguchi method was used to determine the processing parameters of ZnO thin films. The Taguchi method with an L9 orthogonal array, signal-to-noise (S/N) ratio, and analysis of variance (ANOVA) is employed to investigate the performances in the deposition operations. The effect and optimization of deposition parameters, comprising the Ar : O2 gas flow ratio of 1 : 6, 1 : 8, and 1 : 10, the arc current of 50 A, 60 A, and 70 A, and the deposition time of 5 min, 10 min, and 15 min, on the electrical resistivity and optical transmittance of the ZnO films are studied. The results indicate that, by using the grey-relational Taguchi method, the optical transmittance of ZnO thin films increases from 88.17% to 88.82% and the electrical resistivity decreases from 5.12×10-3Ω-cm to 4.38×10-3Ω-cm, respectively

The Roles of Social Support and Health Literacy in Self-Management Among Patients With Chronic Kidney Disease

[[abstract]]Aims: To investigate the relationships among social support, health literacy, and self-management, and the factors influencing self-management of chronic kidney disease (CKD). Design: Cross-sectional study. Methods: A random sample of 410 patients was recruited from nephrology clinics. Data were collected using structured questionnaires and chart reviews from January 2013 to February 2014. Hierarchical regression analysis was used to determine the predictive factors of self-management behaviors and ∆R2 to determine each variable's explanatory power. Findings: Health literacy and social support were positively correlated with self-management behaviors. Furthermore, social support, health literacy, and marital status were significant predictors of self-management behaviors. Social support had a relatively greater explanatory power for self-management behaviors than did health literacy. Particularly, healthcare provider support had the greatest influence on patients' self-management behaviors. Conclusions: Health literacy and social support play independent positive roles in self-management behaviors of patients with CKD, with social support having a particularly dominant role. Further research using a systems approach to improving self-management behaviors is necessary to clarify the role of social support. Clinical relevance: Health literacy and social support are independently and positively related to self-management. Social support, which is a system-level factor, is a relatively stronger and crucial predictor than is health literacy. Nurses have to refine self-management programs to focus on families and adopt a systems approach to help CKD patients improve their self-management behaviors
