Alleviating the Burden of Small-for-Size Graft in Right Liver Living Donor Liver Transplantation Through Accumulation of Experience

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 4 2010
S. C. Chan
The issue of small-for-size graft (SFSG) containing the middle hepatic vein in right liver living donor liver transplantation from 1996 to 2008 (n = 320) was studied. Characteristics of donors, grafts and recipients were comparable between Era I (first 50 cases) and Era II (next 270 cases) except that the median model for end-stage liver disease (MELD) score was higher in Era I (29 vs. 24; p = 0.024). The median graft to standard liver volume ratio (G/SLV) in Era I was 49.0% (range, 32.8,86.2%), versus 49.3% (range, 28.4,89.4%) in Era II (p = 0.498). Hospital mortality rate, the study endpoint, dropped from 16.0% (8/50) in Era I to 2.2% (6/270) in Era II (p = 0.000). Univariate analysis showed that MELD score (p = 0.002), pretransplant hepatorenal syndrome (p = 0.000) and Era I (p = 0.000) were significant in hospital mortality. Logistic regression analysis showed that only Era I (relative risk 9.758; 95% confidence interval, 2.885,33.002; p = 0.000) was significant. In Era I, G/SLV<40% had a relative risk of 7.8 (95% confidence interval, 1.225,49.677; p = 0.030). The hospital mortality rates for G/SLV<40% were 50% (3/6) and 1.9% (1/52) in Era I and II respectively. In conclusion, through accumulation of experience, SFSG became less important as a factor in hospital mortality. [source]


Pyogenic liver abscesses: a comparison of older and younger patients

HPB, Issue 3 2001
JA Alvarez
Background Pyogenic liver abscess is a life-threatening disease. Few studies have specifically explored the way in which the clinical features and management of elderly patients with pyogenic liver abscess differ from those of younger individuals. Methods A retrospective study was undertaken to evaluate whether older patients with pyogenic liver abscess have distinctive presenting features or whether their management and outcome differ from that of younger patients. A total of 133 patients with liver abscess treated in five hospitals during 13 years comprised two groups: 78 patients aged 60 years or above (older group) and 55 patients below age 60 years (younger group). Clinical features, laboratory data, imaging and microbiological findings, management and outcome were determined in each group. Results The older group contained more patients with associated diseases (p = 0.03), nausea and vomiting at presentation (p = 0.02), higher APACHE II (Acute Physiological and Chronic Health Evaluation II scale) score (p < 0.001) and blood urea nitrogen (p < 0.001) and serum creatinine levels (p = 0.002). Multiple abscess (p = 0.05) and bilobar (p = 0.03) abscess were also commoner in this group. By contrast, in the younger group men predominated (p = 0.01), and there was a higher overall complication rate (p = 0.05). Time to diagnosis, hospital mortality rate and other variables analysed were similar in both groups. Discussion Elderly patients with pyogenic liver abscess have some subtle differences in clinical and laboratory presentation, but these do not appear to delay diagnosis. Active management is tolerated well, with a lower morbidity rate than in younger patients and no difference in the mortality rate. [source]


Long-Term Effectiveness of Operative Procedures for Stanford Type A Aortic Dissections

JOURNAL OF CARDIAC SURGERY, Issue 3 2004
Rudolf Driever
Methods: From 1990 to 1999, 50 patients (32 men (64.07%); 18 women, (36.0%); mean age 57.4 ± 11.1 years) underwent operation for ascending aortic dissection. Surgical strategies included aortic root replacement with a composite graft (21/50; 42.0%), valve replacement with supracoronary ascending aortic graft (3/50, 6%), and valve preservation or repair (26/50; 52.0%). Results: Overall hospital mortality rate was 18.0%. Follow-up was completed for 47 patients (94.0%) and ranged from 1 month to 10.5 years (mean 28.8 months). Actuarial survival for patients discharged from the hospital was 84% at 1 year, 75% at 5 years, and 66% at 10 years. There was no significant difference between the various procedures regarding mortality, neurological complications, long-term survival, and proximal reoperations. The ascending aorta alone was replaced in 8 of 50 patients (16%), ascending and hemiarch in 30 of 50 patients (60%), and arch and proximal descending aorta in 12 of 50 patients (24%). Hospital mortality (11.5%, 20.0%, and 16.7%, respectively; p > 0.05) and 5- and 10-year survival (p > 0.05) were not statistically dependent on the extension of the resection distally. Residual distal dissection was not associated with a decrease in late survival. With regard to emergency surgery (36/50) there was no significant difference in hospital mortality (p > 0.05) and 5-year survival (p > 0.05) between those who had undergone coronary angiography (19/36; 52.8%) on the day of surgery with those who had not (17/36; 47.2%). Conclusions: Preservation or repair of the aortic valve can be recommended in the majority of patients with type A dissection. Distal extension of the resection does not increase surgical risk. Residual distal dissection does not decrease late survival. Preoperative coronary angiography may not affect survival in patients undergoing emergency surgery.

Predicting mortality in patients with malarial acute renal failure

NEPHROLOGY, Issue 1-2 2000
Eli K Westerlund
SUMMARY: Acute Physiology and Chronic Health Evaluation (APACHE) III scores, calculated within the first 24 h of admission, were analysed in 108 patients with acute renal failure due to falciparum malaria who were admitted to Bangkok Hospital for Tropical Diseases, Thailand. Twelve (11.1%) patients died. The mean APACHE III score was 82.0 ± 25.5 (range, 45,171). There was a close relation between the APACHE III score and the hospital mortality rate. The non-survivors had significantly higher APACHE III scores than the survivors, 109.8 ± 36.7 and 75.7 ± 21.6, respectively (P < 0.001). Patients with APACHE III score , 82 had a 4.2-fold higher risk of dying compared with patients with a lower score (95% CI 1.2,14.7; P = 0.013). Haemodialysis treatment was performed in 97 (89.8%) of the patients. The mean APACHE III score for patients who were not treated with haemodialysis (95.9 ± 38.0) was not significantly higher than those who received haemodialysis (80.4 ± 23.5; P > 0.05), but the former had a 4.4-times higher risk of dying compared with those dialysed (95% CI 1.6,12.3; P = 0.019). Using the APACHE III score and its ability to predict death, we calculated its sensitivity, specificity and accuracy to be 0.92, 0.31 and 0.41, respectively, at a cut-off score of 67 points. The area under the receiver operating characteristic (ROC) curve was 0.75. The APACHE III scoring system correlated well with the outcome of critically ill malaria patients with acute renal failure, although it was not possible to identify individual survivors or non-survivors. APACHE III should not be used for individual prognosis or treatment decisions. [source]


Delay of Adequate Empiric Antibiotic Therapy Is Associated with Increased Mortality among Solid-Organ Transplant Patients

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 7 2009
B. Hamandi
Empiric antibiotic therapy is often prescribed prior to the availability of bacterial culture results. In some cases, the organism isolated may not be susceptible to initial empiric therapy (inadequate empiric therapy or IET). In solid-organ transplant recipients, the overall incidence and clinical importance of IET is unknown. We performed a retrospective cohort study of patients admitted from 2002 to 2004. Multiple logistic regression analyses were conducted to determine associations between potential determinants and mortality. IET was administered in 169/312 (54%) patients, with a hospital mortality rate that was significantly greater than those receiving adequate therapy (24.9% vs. 7.0%; relative risk [RR] 3.55; 95% confidence interval [CI], 1.85,6.83; p < 0.001). Regression analysis demonstrated that an increasing duration of IET (adjusted odds ratio [OR] at 24 h: 1.33; 95% CI: 1.15,1.53; p < 0.001), ICU-associated infections (adjusted OR: 6.27; 95% CI: 2.79,14.09; p < 0.001), prior antibiotic use (adjusted OR: 3.56; 95% CI: 1.51,8.41; p = 0.004) and increasing APACHE-II scores (adjusted OR: 1.26; 95% CI: 1.16,1.34; p < 0.001) were independently correlated with hospital mortality. IET is common and appears to be associated with an increased hospital mortality rate in the solid-organ transplant population. [source]


Effect of centralization of pancreaticoduodenectomy on nationwide hospital mortality and length of stay

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 11 2007
B. Topal
Background: Despite the persistence of large differences in operative mortality rates between centres, the value of centralization of pancreaticoduodenectomy (PD) remains under debate. This cohort study analysed the effect of centralization of PD on nationwide hospital mortality and length of hospital stay in Belgium. Methods: Data on in-hospital mortality and duration of hospital stay after PD from 2000 to 2004 were obtained from the Belgian national registry database. Analysis of mortality and hospital stay was based on 1842 PDs from all 126 hospitals. Logistic regression analysis was used to assess the effect of patient referral on the national mortality rate. Results: The national mortality rate was 8·4 per cent and the median duration of hospital stay after operation was 21·6 (range 3,117) days. There was a significant relationship between the annual number of PDs per hospital and both mortality rate (P = 0·005) and hospital stay (P = 0·027). Application of a cut-off volume of ten PDs per year per centre would necessitate 56·8 per cent of all patients being referred, resulting in an expected national mortality rate of 6·0 per cent. Conclusion: Referral of patients to more experienced centres for PD is expected to result in a significant reduction in hospital mortality rate and duration of hospital stay, regardless of the experience of the referring centre. Action towards centralization should be undertaken nationwide. Copyright © 2007 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd. [source]


Effect of an Independent-capacity Protocol on Overcrowding in an Urban Emergency Department

ACADEMIC EMERGENCY MEDICINE, Issue 12 2009
Won Chul Cha MD
Abstract Objectives:, The authors hypothesized that a new strategy, termed the independent-capacity protocol (ICP), which was defined as primary stabilization at the emergency department (ED) and utilization of community resources via transfer to local hospitals, would reduce ED overcrowding without requiring additional hospital resources. Methods:, This is a before-and-after trial that included all patients who visited an urban, tertiary care ED in Korea from July 2006 to June 2008. To improve ED throughput, introduction of the ICP gave emergency physicians (EPs) more responsibility and authority over patient disposition, even when the patients belonged to another specific clinical department. The ICP utilizes the ED as a temporary, nonspecific place that cares for any patient for a limited time period. Within 48 hours, EPs, associated specialists, and transfer coordinators perform secondary assessment and determine patient disposition. If the hospital is full and cannot admit these patients after 48 hours, the EP and transfer coordinators move the patients to other appropriate community facilities. We collected clinical data such as sex, age, diagnosis, and treatment. The main outcomes included ED length of stay (LOS), the numbers of admissions to inpatient wards, and the mortality rate. Results:, A total of 87,309 patients were included. The median number of daily patients was 114 (interquartile range [IQR] = 104 to 124) in the control phase and 124 (IQR = 112 to 135) in the ICP phase. The mean ED LOS decreased from 15.1 hours (95% confidence interval [CI] = 14.8 to 15.3) to 13.4 hours (95% CI = 13.2 to 13.6; p < 0.001). The mean LOS in the emergency ward decreased from 4.5 days (95% CI = 4.4 to 4.6 days) to 3.1 days (95% CI = 3.0 to 3.2 days; p < 0.001). The percentage of transfers from the ED to other hospitals decreased from 3.5% to 2.5% (p < 0.001). However, transfers from the emergency ward to other hospitals increased from 2.9% to 8.2% (p < 0.001). Admissions to inpatient wards from the ED were significantly reduced, and admission from the emergency ward did not change. The ED mortality and hospital mortality rates did not change (p = 0.15 and p = 0.10, respectively). Conclusions:, After introduction of the ICP, ED LOS decreased without an increase in hospital capacity. [source]
