Outcomes of kidney allograft in recipients with kidney disease of unknown etiology

The etiology of renal disease is important because the primary renal pathology may affect the outcomes of kidney allograft with respect to recurrence, rejection, and survival. However, for a significant number of patients who undergo kidney transplantation, the disease etiology is unknown. Here, allograft outcomes for patients with kidney disease of unknown etiology (UEK) at three affiliated Korean hospitals were identified. The incidence of biopsy‐proven acute rejection (BPAR) for UEK was 22.9%, which was similar to the rates for diabetic nephropathy (DN, 24.4%) and IgA nephropathy (IgAN, 20.0%; p = 0.345). The cumulative incidence of post‐transplant glomerulonephritis (PTGN) among patients with UEK was significantly lower than that among patients with IgAN (p < 0.001). Overall graft survival of the UEK group was superior to that of the DN group (hazards ratio 0.39, 95% confidence interval 0.17–0.92, p = 0.030). Preemptive transplantation for UEK significantly reduced the incidence of BPAR (preemptive vs. non‐preemptive 9.6% vs. 30.3%, p = 0.001), but graft survival and recurrence were not affected by preemptive transplantation. The outcomes of kidney transplantation for patients with UEK were not inferior to those for patients with IgAN or DN. Preemptive kidney transplantation may be encouraged for UEK patients.     

Robot Versus Laparoscopic Gastrectomy for Cancer by an Experienced Surgeon: Comparisons of Surgery, Complications, and Surgical Stress

Background

No previous robotic studies present an equivalent surgical quality comparison in an experienced setting for gastric cancer. In addition, a reliable postoperative complication assessment is needed to accurately evaluate surgical outcomes.

Methods

After 20 cases of robotic-assisted gastrectomy (RAG), a total of 121 consecutive gastric cancer patients underwent gastrectomy (38 RAG vs 83 laparoscopic-assisted gastrectomy [LAG]) from February 2009 to November 2010 at the Department of Surgery, Korea University Anam Hospital, Seoul, Korea. The Clavien-Dindo (C-D) classification was used to classify surgical complications. The granulocyte-to-lymphocyte (G:L) ratio was analyzed to evaluate surgical stress.

Results

The baseline characteristics, with the exception of age, were similar. The mean total operation time for RAG (234.4 ± 48.0 min) was not significantly different than that for LAG (220.0 ± 60.6 min; P = 0.198). However, in obese patients, fewer lymph nodes were harvested by RAG (23.4 ± 7.0) than by LAG (32.2 ± 12.5, P = 0.006). Overall C-D complications were more common for RAG (47.3 vs 38.5 %), but the difference was not significant (P = 0.361). The mean hospital stay was similar for the 2 groups. Surgical stress as estimated by the G:L ratio was comparable between the 2 groups.

Conclusions

RAG performed by an experienced surgeon resulted in similar postoperative outcomes and complications to those of LAG. Assessment of operation time, C-D complication grade, and G:L ratio revealed that RAG is a practical and feasible alternative to LAG, with the possible exception of obese patients.     

An oral hygiene brochure for your implant overdenture patients

Although there may not be a direct association between oral hygiene and implant failure, oral hygiene must be maintained around implants in the edentulous mouth. Bacterial plaque on dentures can act as a reservoir for pathogens that cause respiratory disease. Unfortunately, many edentulous patients have poor oral hygiene. In this article, we describe the development of a brochure to educate patients wearing mandibular overdentures supported by 2 implants as a supplement to the dentist"s verbal instructions. Dental literature and several specialists were consulted during preparation of the brochure, which contains photographs accompanying oral hygiene instructions. It was sent to 25 participants who were subsequently called and questioned regarding its content and their oral hygiene habits. The 24 respondents found the brochure useful; most reported that they would keep the brochure for future reference and that they learned something new about how to maintain their implants properly. No one found the brochure too long or unclear. Most participants read the brochure entirely, rather than skimming it. The brochure is available to all clinicians who wish to incorporate this tool into their implant overdenture therapeutic approach.     

Predictors of mortality and cost among surgical patients requiring rapid response team activation

BackgroundPrior studies of rapid response team (RRT) implementation for surgical patients have demonstrated mixed results with respect to reductions in poor outcomes. The aim of this study was to identify predictors of in-hospital mortality and hospital costs among surgical inpatients requiring RRT activation.MethodsWe analyzed data prospectively collected from May 2012 to May 2016 at The Ottawa Hospital. We included patients who were at least 18 years of age, who were admitted to hospital, who received either preoperative or postoperative care, and and who required RRT activation. We created a multivariable logistic regression model to describe mortality predictors and a multivariable generalized linear model to describe cost predictors.ResultsWe included 1507 patients. The in-hospital mortality rate was 15.9%. The patient-related factors most strongly associated with mortality included an Elixhauser Comorbidity Index score of 20 or higher (odds ratio [OR] 3.60, 95% confidence interval [CI] 1.96–6.60) and care designations excluding admission to the intensive care unit and cardiopulmonary resuscitation (OR 3.52, 95% CI 2.25–5.52). The strongest surgical predictors included neurosurgical admission (OR 2.09, 95% CI 1.17–3.75), emergent surgery (OR 2.04, 95% CI 1.37–3.03) and occurrence of 2 or more operations (OR 1.73, 95% CI 1.21–2.46). Among RRT factors, occurrence of 2 or more RRT assessments (OR 2.01, 95% CI 1.44–2.80) conferred the highest mortality. Increased cost was strongly associated with admitting service, multiple surgeries, multiple RRT assessments and medical comorbidity.ConclusionRRT activation among surgical inpatients identifies a population at high risk of death. We identified several predictors of mortality and cost, which represent opportunities for future quality improvement and patient safety initiatives.     

Time to Administration of Antibiotics among Inpatients with Severe Sepsis or Septic Shock

Background

Current evidence suggests that administration of appropriate antibiotic therapy within 1 h after the onset of hypotension significantly improves mortality rates among patients with severe sepsis and septic shock.

Objectives:

To determine the interval from recognition of severe sepsis or septic shock in inpatients to initial administration of antibiotic and to assess institutional compliance with the Surviving Sepsis Campaign’s recommendation for early antibiotic therapy.

Methods:

A 6-month retrospective chart analysis was conducted to determine the interval from documented onset of hypotension to initial administration of antibiotic for patients with severe sepsis or septic shock. Patients who were admitted to a general medicine ward, a surgery ward, or the intensive care unit (ICU) of a 475-bed university-affiliated hospital and who met the criteria for severe sepsis or septic shock were eligible for inclusion. Patients who received antibiotics before meeting the criteria for severe sepsis or septic shock were excluded.

Results:

Charts for 100 patients with severe sepsis or septic shock were reviewed. The mean age was 69.0 years (standard deviation 18.7 years), and 56% were men. The median interval from onset of severe sepsis or septic shock to administration of antibiotic was 4.00 h (interquartile range [IQR] 1.80–6.45 h). The median interval from the time a physician ordered an antibiotic to administration of the drug was 1.28 h (IQR 0.57–3.05 h). The interval between ordering and administration differed significantly for patients on the wards (5.67 h), those with onset in the ICU (4.00 h), and those with onset in the emergency department (3.28 h) (p = 0.039). The overall survival rate was 56%.

Conclusion:

At the study hospital, the interval from onset of severe sepsis or septic shock to initial administration of antibiotic to inpatients exceeded the 1-h period recommended by the Surviving Sepsis Campaign. These results will be used as a baseline for future quality assurance and improvement initiatives aimed at minimizing the time to antibiotic administration for this group of patients, who are at high risk of death.
