ABSTRACT Physician values regarding the benefit of continued medical therapy vs colectomy for moderate ulcerative colitis have not been defined. If physicians perceive these states differently than patients, their therapeutic recommendations may not align with patient values.
This study aimed to compare physician and patient willingness to trade life years with moderately active ulcerative colitis vs undergoing colectomy.
This survey of physicians' and patients' utility values used standardized scenarios for moderately active ulcerative colitis and colectomy.
The investigation was conducted at a tertiary academic medical center.
Gastroenterologists, colorectal surgeons, and patients with ulcerative colitis who were either living with moderate disease or were postcolectomy completed the survey.
Utility values were measured by the use of the time trade-off method.
We surveyed 17 physicians, 150 postcolectomy patients, and 69 patients with moderate ulcerative colitis. Utility values for ulcerative colitis and colectomy states were (0.87, 0.95), (0.86, 0.92), and (0.91, 0.91). On average, physicians and postcolectomy patients assessed the utility of life with ulcerative colitis more poorly than the postcolectomy state. Patients with moderately active ulcerative colitis who had not undergone colectomy viewed both health states equally.
This study was limited by the physician subject sample size.
Patients living with moderate ulcerative colitis value the pre- and postcolectomy states differently than physicians and postcolectomy patients. Recognizing the differences between their own and patients' values may help physicians to better counsel patients preoperatively. In addition, exposure to postcolectomy patients may help those with moderate disease who are weighing the comparative benefits of colectomy.

    ABSTRACT: Background Recent events in healthcare reform have brought national attention to integrating patient experiences and expectations into quality metrics. Few studies have comprehensively evaluated the effect of patient expectations on patient-reported outcomes (PROs) following surgery. The purpose of this study is to systematically review the available literature describing the relationship between patient expectations and postoperative PROs. Methods We performed a search of the literature published prior to November 1, 2012. Articles were included in the review if 1) primary data were presented 2) patient expectations regarding a surgical procedure were measured 3) PROs were measured, and 4) the relationship between patient expectations and PROs was specifically examined. PROs were categorized into five subgroups: satisfaction, quality of life (QOL), disability, mood disorder, and pain. We examined each study to determine the relationship between patient expectations and PROs as well as study quality. Results From the initial literature search yielding 1,708 studies, 60 articles were included. Fulfillment of expectations was associated with improved PROs among 24 studies. Positive expectations were correlated with improved PROs for 28 (47%) studies, and poorer PROs for 9 (15%) studies. Eighteen studies reported that fulfillment of expectations was correlated with improved patient satisfaction, and 10 studies identified that positive expectations were correlated with improved postoperative QOL. Finally, patients with positive preoperative expectations reported less pain (8 studies) and disability (15 studies) compared with patients with negative preoperative expectations. Conclusions Patient expectations are inconsistently correlated with PROs following surgery, and there is no accepted method to capture perioperative expectations. Future efforts to rigorously measure expectations and explore their influence on postoperative outcomes can inform clinicians and policy-makers seeking to integrate PROs into measures of surgical quality.

    ABSTRACT: Objective To establish the perceptions, attitudes, experiences, and satisfaction with clinical management of ulcerative colitis (UC) patients, particularly in aspects related to treatment. Methods A qualitative, descriptive, exploratory study. A discussion group was performed in patients who were in remission according to the criteria of the Mayo index, who had never taken biologics or corticosteroids in the past year. They were selected by: course (mild/moderate), time since onset (under 5 years/5 to 9 years/10 years or more), follow-up area (primary care [PC]-hospital/PC-specialist care/hospital), treatment (yes/no), UC care unit (yes/no), belongs to patient associations (yes/no) and sex. A descriptive–interpretative content analysis was performed to detect emerging categories, providing them with an explanatory framework. Results Diagnostic delay was detected due to lack of clinical suspicion from PC and delayed diagnostic tests. For follow-up, patients prefer care on demand, channeled through remote care, which helps to resolve questions, problems with treatment, or when a relapse occurs, minimizing visits to the hospital. They demand more information, both about UC and treatment. The expectations about treatments are limited, so they mainly requested efficacy and safety. Conclusion The results suggest the importance of developing strategies to facilitate care on demand and remote care, and to investigate on effective and safe treatments to minimize the detriment to quality of life of patients. These strategies should guarantee fast care and, together with safe and effective treatments, optimize the management of UC patients.

    ABSTRACT: Background Anti-TNFα agents are commonly used for ulcerative colitis (UC) therapy in the event of non-response to conventional strategies or as colon-salvaging therapy. The objectives were to assess the appropriateness of biological therapies for UC patients and to study treatment discontinuation over time, according to appropriateness of treatment, as a measure of outcome. Methods We selected adult ulcerative colitis patients from the Swiss IBD cohort who had been treated with anti-TNFα agents. Appropriateness of the first-line anti-TNFα treatment was assessed using detailed criteria developed during the European Panel on the Appropriateness of Therapy for UC. Treatment discontinuation as an outcome was assessed for categories of appropriateness. Results Appropriateness of the first-line biological treatment was determined in 186 UC patients. For 64% of them, this treatment was considered appropriate. During follow-up, 37% of all patients discontinued biological treatment, 17% specifically because of failure. Time-to-failure of treatment was significantly different among patients on an appropriate biological treatment compared to those for whom the treatment was considered not appropriate (p = 0.0007). Discontinuation rate after 2 years was 26% compared to 54% between those two groups. Patients on inappropriate biological treatment were more likely to have severe disease, concomitant steroids and/or immunomodulators. They were also consistently more likely to suffer a failure of efficacy and to stop therapy during follow-up. Conclusion Appropriateness of first-line anti-TNFα therapy results in a greater likelihood of continuing with the therapy. In situations where biological treatment is uncertain or inappropriate, physicians should consider other options instead of prescribing anti-TNFα agents.
