How do you know if you are any good? A surgeon performance feedback system for the outcomes of radical prostatectomy

Surgery remains a mainstay of initial treatment for prostate cancer, with an estimated 85,000 operations per year in the US. Radical prostatectomy is associated with important risks of erectile dysfunction, urinary incontinence and, naturally, cancer recurrence. Given the possible consequences, it would be reassuring were it known that urologic surgeons offer uniformly high-quality care. Unfortunately, the data suggest that this is far from the case. There is copious evidence that surgeons with greater case volume or total lifetime experience have better outcomes. For example, low volume surgeons have complication rates 6 to 8% greater than their higher volume counterparts; in studies on the learning curve, the risk of recurrence is about 7% higher for a typical patient treated by an inexperienced surgeon than if treated by a more experienced surgeon There are also data that differences in outcome go over and above characteristics such as volume or experience, with large variations between surgeons even within volume categories, with one study reporting a five-fold variation in potency rates between surgeons at a single institution

Phase II Study of a Non-Platinum–Containing Doublet of Paclitaxel and Pemetrexed with Bevacizumab as Initial Therapy for Patients with Advanced Lung Adenocarcinomas

Many patients with lung cancers cannot receive platinum-containing regimens due to co-morbid medical conditions. We designed the PPB regimen of paclitaxel, pemetrexed, and bevacizumab to maintain or improve outcomes while averting the unique toxicities of platinum-based chemotherapies

Validation study of a web-based assessment of functional recovery after radical prostatectomy

<p>Abstract</p> <p>Background</p> <p>Good clinical care of prostate cancer patients after radical prostatectomy depends on careful assessment of post-operative morbidities, yet physicians do not always judge patient symptoms accurately. Logistical problems associated with using paper questionnaire limit their use in the clinic. We have implemented a web-interface ("STAR") for patient-reported outcomes after radical prostatectomy.</p> <p>Methods</p> <p>We analyzed data on the first 9 months of clinical implementation to evaluate the validity of the STAR questionnaire to assess functional outcomes following radical prostatectomy. We assessed response rate, internal consistency within domains, and the association between survey responses and known predictors of sexual and urinary function, including age, time from surgery, nerve sparing status and co-morbidities.</p> <p>Results</p> <p>Of 1581 men sent an invitation to complete the instrument online, 1235 responded for a response rate of 78%. Cronbach's alpha was 0.84, 0.86 and 0.97 for bowel, urinary and sexual function respectively. All known predictors of sexual and urinary function were significantly associated with survey responses in the hypothesized direction.</p> <p>Conclusions</p> <p>We have found that web-based assessment of functional recovery after radical prostatectomy is practical and feasible. The instrument demonstrated excellent psychometric properties, suggested that validity is maintained when questions are transferred from paper to electronic format and when patients give responses that they know will be seen by their doctor and added to their clinic record. As such, our system allows ready implementation of patient-reported outcomes into routine clinical practice.</p

Software for administering the National Cancer Institute’s patient-reported outcomes version of the common terminology criteria for adverse events: Usability study

Background: The US National Cancer Institute (NCI) developed software to gather symptomatic adverse events directly from patients participating in clinical trials. The software administers surveys to patients using items from the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) through Web-based or automated telephone interfaces and facilitates the management of survey administration and the resultant data by professionals (clinicians and research associates). Objective: The purpose of this study was to iteratively evaluate and improve the usability of the PRO-CTCAE software. Methods: Heuristic evaluation of the software functionality was followed by semiscripted, think-aloud protocols in two consecutive rounds of usability testing among patients with cancer, clinicians, and research associates at 3 cancer centers. We conducted testing with patients both in clinics and at home (remotely) for both Web-based and telephone interfaces. Furthermore, we refined the software between rounds and retested. Results: Heuristic evaluation identified deviations from the best practices across 10 standardized categories, which informed initial software improvement. Subsequently, we conducted user-based testing among 169 patients and 47 professionals. Software modifications between rounds addressed identified issues, including difficulty using radio buttons, absence of survey progress indicators, and login problems (for patients) as well as scheduling of patient surveys (for professionals). The initial System Usability Scale (SUS) score for the patient Web-based interface was 86 and 82 (P=.22) before and after modifications, respectively, whereas the task completion score was 4.47, which improved to 4.58 (P=.39) after modifications. Following modifications for professional users, the SUS scores improved from 71 to 75 (P=.47), and the mean task performance improved significantly (4.40 vs 4.02; P=.001). Conclusions: Software modifications, informed by rigorous assessment, rendered a usable system, which is currently used in multiple NCI-sponsored multicenter cancer clinical trials
