Morbidity and Mortality After Benign Prostatic Hyperplasia Surgery: Data from the American College of Surgeons National Surgical Quality Improvement Program
Background and Purpose: With the aging population, it is becoming increasingly important to identify patients at risk for postsurgical complications who might be more suited for conservative treatment. We sought to identify predictors of morbidity after surgical treatment of benign prostatic hyperplasia (BPH) using a large national contemporary population-based cohort. Methods: Relying on the American College of Surgeons National Surgical-Quality Improvement Program (ACS-NSQIP; 2006?2011) database, we evaluated outcomes after transurethral resection of the prostate (TURP), laser vaporization of the prostate (LVP), and laser enucleation of the prostate (LEP). Outcomes included blood-transfusion rates, length of stay, complications, reintervention rates, and perioperative mortality. Multivariable logistic-regression analysis evaluated the predictors of perioperative morbidity and mortality. Results: Overall, 4794 (65.2%), 2439 (33.1%), and 126 (1.7%) patients underwent TURP, LVP, and LEP, respectively. No significant difference in overall complications (P=0.3) or perioperative mortality (P=0.5) between the three surgical groups was found. LVP was found to be associated with decreased blood transfusions (odds ratio [OR]=0.21; P=0.001), length of stay (OR=0.12; P30%) levels were the only predictors of lower overall complications and perioperative mortality. Conclusions: All three surgical modalities for BPH management were found to be safe. Advanced age and non-Caucasian race were independent predictors of adverse outcomes after BPH surgery. In patients with these attributes, conservative treatment might be a reasonable alternative. Also, preoperative hematocrit and albumin levels represent reliable predictors of adverse outcomes, suggesting that these markers should be evaluated before BPH surgery.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/140378/1/end.2013.0805.pd
Framework for agile development using cloud computing: A survey
Agile methods are based on frequent delivery of software, improved customer satisfaction, closed interaction with the clients and accommodation of requirement change at any stage of development. However, several challenges exist such as scalability, transparency, face-to-face communication, smooth control of development, and ability to build applications from distributed locations. A framework proposed for Agile Development using Cloud Computing (ADCC) in the earlier study is evaluated in the current study. The Malaysia Research and Education Network cloud is utilized to implement the framework. An industrial survey is conducted to evaluate the framework. The results of the industrial survey show that the ADCC framework has a positive impact on the performance of agile methods and overcomes some challenges found in distributed agile development. Furthermore, the survey verifies the challenges in agile development and the solutions covers these challenges so far
Robot-assisted vs. Laparoscopic Partial Nephrectomy: utilization rates and perioperative outcomes
Objectives To examine the effect of surgical approach on perioperative morbidity and mortality after partial nephrectomy. Materials and Methods Within the Nationwide Inpatient Sample, patients who underwent RAPN or LPN between October 2008 and December 2009 were identified. Propensity-based matching was performed to adjust for potential baseline differences between the two groups. The rates of intraoperative and postoperative complications, blood transfusions, prolonged length of stay, and in-hospital mortality, stratified according to RAPN vs. LPN, were compared. Results Overall, 851 (72.5%) patients underwent RAPN and 323 (27.5%) underwent LPN. For RAPN and LPN respectively, the following rates were recorded in the propensity-score matched cohort: blood transfusions, 4.5 vs. 6.8% (p = 0.223); intraoperative complications, 5.2 vs. 2.6% (p = 0.096); postoperative complications, 10.6 vs. 13.5% (p = 0.268); prolonged length of stay, 6.8 vs. 9.4% (p = 0.238); in-hospital mortality, 0.0 vs. 0.0%. Conclusions RAPN has supplanted LPN as the predominant minimally invasive surgical approach for renal masses. Perioperative outcomes after RAPN and LPN are comparable. Interpretation of these findings needs to take into account the lack of adjustment for case complexity and surgical expertise
An evaluation of the \u27weekend effect\u27 in patients admitted with metastatic prostate cancer.
OBJECTIVES: To investigate whether mortality is increased for patients with metastatic prostate cancer (mCaP) admitted over the weekend.
PATIENTS AND METHODS: Using the Nationwide Inpatient Sample (NIS) between 1998 and 2009, admitted patients with a diagnosis of prostate cancer and concomitant metastases were identified. Rates of in-hospital mortality, complications, use of imaging and procedures were assessed. Adjusted logistic regression models examined associations of mortality and complications.
RESULTS: A weighted sample of 534,011 patients with mCaP was identified, including 81.7% weekday and 18.3% weekend admissions. Of these, 8.6% died after a weekday vs 10.9% after a weekend admission (P \u3c 0.001). Patients admitted over the weekend were more likely to be treated at rural (17.8% vs 15.7%), non-teaching (57.6% vs 53.7%) and low-volume hospitals (53.4% vs 49.4%) (all P \u3c 0.001) compared with weekday admissions. They presented higher rates of organ failure (25.2% vs 21.3%), and were less likely to undergo an interventional procedure (10.6% vs 11.4%) (all P \u3c 0.001). More patients admitted over the weekend had pneumonia (12.2% vs 8.8%), pyelonephritis (18.3% vs 14.1%) and sepsis (4.5% vs. 3.5%) (all P \u3c 0.001). In multivariate analysis, weekend admission was associated with an increased likelihood of complications (odds ratio [OR] 1.15, 95% confidence Interval [CI] 1.11-1.19) and mortality (OR 1.20, 95% CI 1.14-1.27).
CONCLUSION: In patients with mCaP weekend admissions are associated with a significant increase in mortality and morbidity. Our findings suggest that weekend patients may present with more acute medical issues; alternatively, the quality of care over the weekend may be inferior
European association of urology section of urolithiasis and international alliance of urolithiasis joint consensus on retrograde intrarenal surgery for the management of renal stones
Background: Retrograde intrarenal surgery (RIRS) has become the preferred treatment modality for nephrolithiasis. However, because of ongoing uncertainties regarding the optimal perioperative management, operative technique, and postoperative follow-up, as well as a lack of standardization for outcome reporting, consensus is needed to achieve more uniform clinical practice worldwide. Objective: To develop recommendations for RIRS on the basis of existing data and expert consensus. Design, setting, and participants: A protocol-driven, three-phase study was conducted by the European Association of Urology Section of Urolithiasis (EULIS) and the International Alliance of Urolithiasis (IAU). The process included: (1) a nonsystematic review of the literature to define domains for discussion; (2) a two-round modified Delphi survey involving experts in this field; and (3) an additional group meeting and third-round survey involving 64 senior representative members to formulate the final conclusions. Outcome measurements and statistical analysis: The results from each previous round were returned to the participants for re-evaluation of their decisions during the next round. The agreement threshold was set at 70%. Results and limitations: The panel included 209 participants who developed 29 consensus statements on the following topics of interest: (1) perioperative infection management; (2) perioperative antithrombotic therapy; (3) fundamentals of the operative technique; and (4) standardized outcome reporting. Although this consensus can be considered as a useful reference for more clinically oriented daily practice, we also acknowledge that a higher level of evidence from further clinical trials is needed. Conclusions: The consensus statements aim to guide and standardize clinical practice and research on RIRS and to recommend standardized outcome reporting. Patient summary: An international consensus on the best practice for minimally invasive surgery for kidney stones was organized and developed by two international societies. It is anticipated that this consensus will provide further guidance to urologists and may help to improve clinical outcomes for patients
