YouTube as a source of information for patients considering surgery for ulcerative colitis

© 2017 Elsevier Inc. Background With the range of health information online, assessing the resources that patients access may improve the content of preoperative information. Our aim was to assess the content of the most viewed videos on YouTube related to surgery for ulcerative colitis (UC). Methods YouTube was searched for videos containing information on surgery for UC. The 50 most viewed videos were identified and user interaction analyzed. Upload source was classified as patient, individual health care professional (HCP), or hospital/professional association. Video content was categorized using an inductive thematic analysis on a purposive sample list of videos. The overarching theme of each video was classified once data saturation was achieved. Results Thirty videos were uploaded by patients, 15 by hospitals and 5 by HCPs. Seventeen videos (34%) discussed life after surgery. Sixteen of these were uploaded by patients who had previously undergone surgery for UC. No videos of this theme were uploaded by HCPs. Ten videos (20%) described a number of different operations. Other themes identified were alternative health therapies (12%), colonoscopy (12%), life with UC (8%), miscellaneous (8%), and education for HCPs (6%). Patient uploaded videos had significantly more comments (P = 0.0079), with 28% of comments on patient videos being users requesting further information. Conclusions Understanding the sequelae of surgery is most important to preoperative patients. There are a lack of professional videos addressing this topic on YouTube. HCPs must participate in the production of videos and adapt preoperative consultations to address common preoperative concerns

Patients with perianal Crohn's fistulas experience delays in accessing anti-TNF therapy due to slow recognition, diagnosis and integration of specialist services: lessons learned from three referral centres.

AIM: Crohn's anal fistula should be managed by a multidisciplinary team. There is no clearly defined 'patient pathway' from presentation to treatment. The aim of this study was to describe the patient route from presentation with symptomatic Crohn's anal fistula to starting anti-tumour necrosis factor (anti-TNF) therapy. METHOD: Case note review was undertaken at three hospitals with established inflammatory bowel disease services. Patients with Crohn's anal fistula presenting between 2010 and 2015 were identified through clinical coding and local databases. Baseline demographics were captured. Patient records were interrogated to identify route of access, and clinical contacts during the patient pathway. RESULTS: Seventy-nine patients were included in the study, of whom 54 (68%) had an established diagnosis of Crohn's disease (CD). Median time from presentation to anti-TNF therapy was 204 days (174 vs 365 days for existing and new diagnosis of CD, respectively; P = 0.019). The mean number of surgical outpatient attendances, operations and MRI scans per patient was 1.03, 1.71 and 1.03, respectively. Patients attended a mean of 1.49 medical clinics. Seton insertion was the most common procedure, accounting for 48.6% of all operations. Where care episodes ('clinical events per 30 days') were infrequent this correlated with prolongation of the pathway (r = -0.87; P < 0.01). CONCLUSION: This study highlights two key challenges in the treatment pathway: (i) delays in diagnosis of underlying CD in patients with anal fistula and (ii) the pathway to anti-TNF therapy is long, suggesting issues with service design and delivery. These should be addressed to improve patient experience and outcome

Development and evaluation of a patient decision aid for patients considering ongoing medical or surgical treatment options for ulcerative colitis using a mixed-methods approach : protocol for DISCUSS study

Introduction: Approximately 20%–30% of patients with ulcerative colitis (UC) require surgery, the majority of these being elective due to chronic symptoms refractory to medical treatment. The decision for surgery is difficult and dependent on patient preferences. Current resources for patients considering surgery have been found not to meet minimum international standards. The overall aim of the ‘DISCUSS’ study is to develop and evaluate a new patient decision aid (PtDA) for patients considering surgery for UC created in line with international minimum standards. Methods and analysis: This is a prospective mixed-methods study of adults (18+ years) who are considering surgical intervention for UC across two regional centres in Yorkshire, UK. This study is in three stages. In stage 1 we will develop the PtDA and its content via systematic reviews and a patient questionnaire. In stage 2 we will assess the face validity of the PtDA using mixed-methods on key stakeholders using both semistructured interviews and questionnaires, following which the PtDA will be refined. In stage 3 we will assess the acceptability of using the PtDA in clinical practice. This will use a mixed-methods approach on clinicians and patients who are considering undergoing elective surgery. Questionnaires including the Preparation for Decision-Making Scale, a measure of anxiety and decisional conflict will be analysed at two timepoints using paired sample t-tests and CIs. Interviews with patients and clinicians will be analysed using thematic analysis. Ethics and dissemination: Research ethics approval from North East–Tyne & Wear South Research Ethics Committee (Ref: 19/NE/0073) and Health Research Authority approval (Ref: 257044) have been granted. Results will be published in open access peer-reviewed journals, presented in conferences and distributed through the Crohn’s and Colitis UK charity. External endorsement will be sought from the International Patient Decision Aid Standards Collaboration inventory of PtDAs

Health-state utilities in a prisoner population : a cross-sectional survey

Background: Health-state utilities for prisoners have not been described. Methods: We used data from a 1996 cross-sectional survey of Australian prisoners (n = 734). Respondent-level SF-36 data was transformed into utility scores by both the SF-6D and Nichol's method. Socio-demographic and clinical predictors of SF-6D utility were assessed in univariate analyses and a multivariate general linear model. Results: The overall mean SF-6D utility was 0.725 (SD 0.119). When subdivided by various medical conditions, prisoner SF-6D utilities ranged from 0.620 for angina to 0.764 for those with none/mild depressive symptoms. Utilities derived by the Nichol's method were higher than SF-6D scores, often by more than 0.1. In multivariate analysis, significant independent predictors of worse utility included female gender, increasing age, increasing number of comorbidities and more severe depressive symptoms. Conclusion: The utilities presented may prove useful for future economic and decision models evaluating prison-based health programs

Systematic review of factors affecting transition readiness skills in patients with inflammatory bowel disease.

BACKGROUND AND AIMS: The incidence of inflammatory bowel disease (IBD) diagnosed before adulthood is increasing worldwide. Transition from paediatric to adult healthcare requires certain skills. The aim of this study was to identify factors affecting these skills. METHODS: This review was registered on the PROSPERO database (CRD42019152272). Inclusion criteria: 1) studies of factors affecting transition readiness skills in patients with IBD 2) written in English 3) published since 1999. MEDLINE, CINAHL and PsychINFO databases were searched between 1999-2019. Quality was assessed using the Joanna Briggs Institute critical appraisal tools. RESULTS: Searches identified 822 papers. Sixteen papers were included. Age was positively associated with skills including disease knowledge and performing self-management behaviours (14 studies). Improvement often occurs at 18, however, skill deficiency may still remain. Increased self-efficacy (confidence) was associated with greater disease knowledge and performing self-management behaviours (3 studies). Self-efficacy was positively correlated with transition duration (2 studies) and health-related quality of life (r=0.57, p<0.001) (1 study), negatively correlated with depression (r=-0.57, p<0.001) and anxiety (r=-0.23, p=0.03) (1 study), and associated with higher education level (2 studies) and a family history of IBD (1 study). Females had higher self-management scores (3 studies), and greater healthcare satisfaction was significantly associated with higher knowledge (1 study). Greater transition communication improved knowledge, self-management, and overall transition readiness (2 studies). CONCLUSIONS: Potentially modifiable factors have been identified that could be supported in the transitioning IBD population to improve transition readiness. Identification of those with non-modifiable characteristics associated with poor readiness may aid targeted support

Identification of Recurrent Mutations in the microRNA-Binding Sites of B-Cell Lymphoma-Associated Genes in Follicular Lymphoma

Follicular lymphoma (FL) is a common indolent B-cell lymphoma that can transform into the more aggressive transformed FL (tFL). However, the molecular process driving this transformation is uncertain. In this work, we aimed to identify microRNA (miRNA)-binding sites recurrently mutated in follicular lymphoma patients, as well as in transformed FL patients. Using whole-genome sequencing data from FL tumors, we discovered 544 mutations located in bioinformatically predicted microRNA-binding sites. We then studied these specific regions using targeted sequencing in a cohort of 55 FL patients, found 16 recurrent mutations, and identified a further 69 variants. After filtering for QC, we identified 21 genes with mutated miRNA-binding sites that were also enriched for B-cell-associated genes by Gene Ontology. Over 40% of mutations identified in these genes were present exclusively in tFL patients. We validated the predicted miRNA-binding sites of five of the genes by luciferase assay and demonstrated that the identified mutations in BCL2 and EZH2 genes impaired the binding efficiency of miR-5008 and miR-144 and regulated the endogenous levels of messenger RNA (mRNA)

Mixed integer programming in production planning with backlogging and setup carryover : modeling and algorithms

This paper proposes a mixed integer programming formulation for modeling the capacitated multi-level lot sizing problem with both backlogging and setup carryover. Based on the model formulation, a progressive time-oriented decomposition heuristic framework is then proposed, where improvement and construction heuristics are effectively combined, therefore efficiently avoiding the weaknesses associated with the one-time decisions made by other classical time-oriented decomposition algorithms. Computational results show that the proposed optimization framework provides competitive solutions within a reasonable time

Assessing internet-based information used to aid patient decision-making about surgery for perianal Crohn's fistula.

BACKGROUND: Decision-making in perianal Crohn's fistula (pCD) is preference sensitive. Patients use the internet to access healthcare information. The aim of this study was to assess the online information and patient decision aids relating to surgery for pCD. METHODS: A search of Google™ and the Decision Aids Library Inventory (DALI) was performed using a predefined search strategy. Patient-focussed sources providing information about pCD surgery were included in the analysis. Written health information was assessed using the International Patient Decision Aids Standards (IPDAS) and DISCERN criteria. The readability of the source content was assessed using the Flesch-Kincaid score. RESULTS: Of the 201 sources found, 187 were excluded, leaving 14 sources for analysis. Three sources were dedicated to pCD, and six sources mentioned pCD-specific outcomes. The most common surgical intervention reported was seton insertion (n = 13). The least common surgical intervention reported was proctectomy (n = 1). The mean IPDAS and DISCERN scores were 4.43 ± 1.65 out of 12 (range = 2-8) and 2.93 ± 0.73 out of 5 (range = 1-5), respectively. The mean reading ease was US college standard. CONCLUSIONS: We found no patient decision aids relating to surgery for pCD. The online sources relating to surgery for pCD are few, and their quality is poor, as seen in the low IPDAS and DISCERN scores. Less than half of the sources mentioned pCD-specific outcomes, and three sources were solely dedicated to providing information on pCD. Healthcare professionals should look to create a patient tool to assist decision-making in pCD
