RESUMO

INTRODUCTION: Increasing pressure and limitations on the NHS necessitate simple and effective ways for maintaining standards of patient care. This quality improvement project aims to design and implement user-friendly and clear ward round stickers as an adjunct to surgical ward rounds to evidence standardised care. PROJECT DESIGN AND STRATEGY: Baseline performance was measured against the recommended standards by the Royal College of Physicians, General Medical Council and a study performed at the Imperial College London. A total of 16 items were studied. All members of staff in surgery department were informed that an audit on ward round entries would be implemented but exact dates and times were not revealed. In the first cycle, ward round sticker was implemented and results collected across three random days for use and non-use of sticker. Feedback was collected through the use of questionnaires. In the second cycle, the ward round sticker was redesigned based on feedback and results collected for use and non-use of sticker. RESULTS: Baseline performance noted in 109 ward round entries showed that checking of drug chart, intravenous fluid chart, analgesia, antiemetic, enoxaparin, thromboembolic deterrents ranged from 0% to 6%. With the introduction of ward round stickers in both cycles, there was noticeable improvement from baseline in all items; in ward round entries where stickers were not used, performance was similar to baseline. CONCLUSION: This quality improvement project showed that the use of stickers as an adjunct to surgical ward round is a simple and effective way of evidencing good practice against recommended standards. Constant efforts need to be made to promote compliance and sustainability. Commitment from all levels of staff are paramount in ensuring standardised patient care without overlooking basic aspects.

RESUMO

BACKGROUND: Steatotic livers are increasingly common in the donor population. Cold storage of steatotic livers exacerbates ischemia-reperfuson injury and risks primary nonfunction and recipient death. Normothermic preservation avoids prolonged cooling of the organ and may be well suited to the preservation and resuscitation of damaged livers. By ex vivo normothermic perfusion, it may be possible to preserve and improve steatotic livers, so that transplantation is a viable option. METHODS: In a porcine model, streptozotocin was used to induce a hyperglycemic, ketotic state that, together with a high fat diet, resulted in mild hepatic steatosis at 5 weeks. A blood-based oxygenated ex vivo normothermic preservation system was then used to compare extended preservation of normal and mildly steatotic porcine livers at physiological pressures and flows. Serial liver biopsies were stained with Oil Red O, a specialist triglyceride stain, and were analyzed using custom-designed image analysis to quantify the degree of lipid deposition. RESULTS: Steatotic livers were capable of correcting the perfusate base excess and maintaining factor V and bile production and showed markers of liver injury comparable with normal livers. Steatotic livers had a significantly higher urea production and required no glucose support. Preliminary results suggest that prolonged normothermic perfusion results in a reduction in steatosis. CONCLUSIONS: This study suggests that steatotic livers can be successfully preserved using normothermic preservation for prolonged periods and that normothermic preservation facilitates a reduction in hepatic steatosis. Further studies are now needed including transplantation of steatotic livers after normothermic preservation.

RESUMO

In order to determine the impact of immunosuppression (IS) on the incidence of early subclinical rejection (SCR), we studied two groups of patients receiving different immunosuppressive regimens. Patients received cyclosporin (CsA), azathioprine and prednisolone (group 1; n = 304) or IS according to immunological risk (group 2; n = 150). The highest-risk patients received basiliximab induction, tacrolimus, mycophenolate mofetil (MMF) and prednisolone; medium-risk patients CsA, MMF and prednisolone; low-risk CsA, azathioprine and prednisolone. Protocol biopsies were performed in all patients, irrespective of graft function, on days 7 and 28 post-transplantation. Only patients with good stable function at the time of biopsy were included for assessment of SCR. Group 2 patients showed significant reductions in total rejection frequency (32.6% vs. 57.2%, P = <0.0001) and SCR frequency in day 7 protocol biopsies (2% vs. 13%, P = <0.05). In group 2 patients, all SCRs, but not borderline changes, were treated. Untreated borderline changes did not have an adverse impact on graft function at 1 year post-transplantation. New immunosuppressive regimens may reduce subclinical in addition to clinical rejection-frequency, suggesting that the relative benefit of early protocol biopsies in detecting SCR is also reduced.

RESUMO

BACKGROUND: Treatment with CAMPATH-1H at the time of transplantation allows reduced maintenance immunosuppression. We hypothesized that CAMPATH-1H induction would modulate the response of repopulating leukocytes to donor alloantigens. METHODS: The phenotype, proliferative and stimulatory capacity of peripheral blood leukocytes from 14 renal transplant recipients treated with CAMPATH-1H and reduced immunosuppression with mycophenolate mofetil and tacrolimus were investigated for the first six months after transplantation. The impact of immunosuppressive drugs on leukocytes that escape depletion was also evaluated in vitro. RESULTS: CAMPATH-1H therapy caused a significant decrease in the number of B and T cells, with CD4 T central memory cells being the most resistant to depletion. The recovery of CD8 T cells was faster than that of CD4 T cells. Lymphopenia correlated with a decrease in both proliferative and effector responses, however, the recipient T cells remained responsive to third-party antigens. Dendritic cells (DC) were also depleted but to a lesser extent than lymphocytes; lymphoid DC were more resistant than myeloid DC; these changes correlated with decreased allostimulatory capacity. One of the patients experienced rejection that was treated successfully. The rejection was associated with a high proportion of CD4 T effector memory cells and myeloid DC, increased proliferation and enhanced effector activity to donor antigens. In vitro studies confirmed that the reduced dose of immunosuppressive drugs used could prevent activated T cells from switching to the effector compartment, suppressing both their proliferation and effector activity. CONCLUSIONS: CAMPATH-1H induction combined with reduced maintenance immunosuppression is sufficient to control the effector phase of immune response to donor antigens.
