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

Implantation: Two instead of three embryo transfer in in-vitro fertilization

PubMed ID: 8567858The rational of transferring two instead of three embryos was studied through 468 in-vitro fertilization (IVF) treatment cycles in 287 couples. The quality of 1224 embryos was determined according to the fragmentation rate and the morphology as good (A) and poor (B). The influence of the number of embryos transferred (two or three) on the pregnancy rate when the same quality or combinations of good and poor quality embryos transferred was examined. When only good quality embryos were transferred the pregnancy rates in double (AA) and triple (AAA) embryo transfer were 40.5 (17/42) and 42.9% (30/70) respectively (not significant). When only poor quality embryos were transferred, the pregnancy rates in double (BB) and triple (BBB) embryo transfers were 11.0% (11/ 100) and 22.9% (16/70) respectively (P < 0.001). On the other hand, when good and poor quality embryos were transferred together as AB in double and as AAB and ABB in triple embryo transfer, the pregnancy rates were 36.8 (14/38) and 39.9% (59/148) respectively (not significant). There was no difference in the miscarriage rate between double and triple embryo transfers; 16.7 and 18.1% respectively. The multiple pregnancy rate was 14.3% for double embryo transfers and 32.4% for triple embryo transfers (P < 0.001). This study demonstrates that if there is at least one good quality embryo available for transfer, then double instead of triple embryo transfer will not yield a significantly lower pregnancy rate. The influence of the number of embryos transferred on the pregnancy rate became significant when only poor quality embryos were transferred. In conclusion, as long as at least one good quality embryo is available for transfer, we may consider the transfer of double instead of triple embryos. © 1995 Oxford University Press

The influence of rifamycin decontamination on incorporation of autologous onlay bone grafts in rats: A histometric and immunohistochemical evaluation

Objective Although it has been shown that rifamycin is an effective agent for bone graft decontamination, no information exists on the effects of rifamycin decontamination on bone graft incorporation. The aim of this study was to evaluate the influence of rifamycin decontamination on the incorporation of autologous onlay bone grafts quantitatively. Design In 30 rats, a standardized 5.0-mm-diameter bone graft was harvested from the right mandibular angle, contaminated with saliva, decontaminated with rifamycin solution, and augmented to the left as an onlay graft. Ten animals were sacrificed at 7, 14, and 21 days after surgery. In the control group (10 rats), the onlay grafts were neither contaminated nor decontaminated, and the rats were sacrificed at 21 days after surgery. Histological slides were prepared from each grafted site for both immunohistochemistry analysis (bone morphogenetic protein-2 (BMP-2) and vascular endothelial growth factor (VEGF) antibodies) and histometric analysis. Images obtained from the graft incorporation area with the light microscope were transferred to a PC, and they were evaluated using Clemex PE 3.5 image analysis software. Results The grafts were fully incorporated in all specimens. The results showed that rifamycin decontamination has no detrimental effect on graft incorporation and the findings revealed a tendency for earlier revascularization and osteogenesis in the decontamination group. Data were analyzed using variance analysis and Tukey's test. Conclusions Rifamycin decontamination has no detrimental effect on autogenous graft incorporation, and it can be used for graft decontamination with confidence. © 2014 Elsevier Ltd.
