Stoma Formation in Crohn's Disease and the Likelihood of Antidepressant Use: A Population-Based Cohort Study.

BACKGROUND & AIMS: The impact of a temporary or permanent stoma on mental health in Crohn's Disease (CD) is unknown. The aim was to examine the association between intestinal surgery and stoma formation and subsequent antidepressant medication (ADM) use. METHODS: Using the Clinical Practice Research Datalink, we identified individuals with CD who underwent intestinal surgery between 1998-2018. We excluded individuals with a prescription for an ADM in the 6 months before surgery. Individuals were stratified into three groups: no stoma, temporary stoma, and permanent stoma. We used Kaplan-Meier curves to examine initiation of ADM after intestinal surgery and Cox regression to identify risk factors for ADM use after intestinal surgery. RESULTS: We identified 1,272 cases of CD undergoing their first intestinal surgery. Of these, 871 (68.5%) had no stoma, 191 (15.0%) had a temporary stoma and 210 (16.5%) had a permanent stoma. The 10-year cumulative incidence of ADM use was 26.4%, 33.4% and 37.3% respectively. Individuals with a permanent stoma were 71% more likely to receive an ADM than those with no stoma (HR 1.71, 95% CI 1.20-2.44). Individuals with a temporary stoma reversed within 12 months had a similar likelihood of ADM use to those without stoma formation (HR 0.99, 95% CI 0.64-1.53) whereas temporary stoma formation with late reversal after 12 months was associated with significantly greater likelihood of ADM use (HR 1.85, 95% CI 1.15-2.96). CONCLUSIONS: Permanent stomas and temporary stomas with late reversal surgery are associated with increased ADM use after intestinal surgery, likely associated with increased anxiety and depression.

Depression in individuals who subsequently develop inflammatory bowel disease: a population-based nested case-control study.

OBJECTIVE: Depression is a potential risk factor for developing IBD. This association may be related to GI symptoms occurring before diagnosis. We aimed to determine whether depression, adjusted for pre-existing GI symptoms, is associated with subsequent IBD. DESIGN: We conducted a nested case-control study using the Clinical Practice Research Datalink identifying incident cases of UC and Crohn's disease (CD) from 1998 to 2016. Controls without IBD were matched for age and sex. We measured exposure to prevalent depression 4.5-5.5 years before IBD diagnosis. We created two sub-groups with prevalent depression based on whether individuals had reported GI symptoms before the onset of depression. We used conditional logistic regression to derive ORs for the risk of IBD depending on depression status. RESULTS: We identified 10 829 UC cases, 4531 CD cases and 15 360 controls. There was an excess of prevalent depression 5 years before IBD diagnosis relative to controls (UC: 3.7% vs 2.7%, CD 3.7% vs 2.9%). Individuals with GI symptoms prior to the diagnosis of depression had increased adjusted risks of developing UC and CD compared with those without depression (UC: OR 1.47, 95% CI 1.21 to 1.79; CD: OR 1.41, 95% CI 1.04 to 1.92). Individuals with depression alone had similar risks of UC and CD to those without depression (UC: OR 1.13, 95% CI 0.99 to 1.29; CD: OR 1.12, 95% CI 0.91 to 1.38). CONCLUSIONS: Depression, in the absence of prior GI symptoms, is not associated with subsequent development of IBD. However, depression with GI symptoms should prompt investigation for IBD.

How an electronic health record became a real-world research resource: comparison between London's Whole Systems Integrated Care database and the Clinical Practice Research Datalink.

BACKGROUND: In the UK, several initiatives have resulted in the creation of local data warehouses of electronic patient records. Originally developed for commissioning and direct patient care, they are potentially useful for research, but little is known about them outside their home area. We describe one such local warehouse, the Whole Systems Integrated Care (WSIC) database in NW London, and its potential for research as the "Discover" platform. We compare Discover with the Clinical Practice Research Datalink (CPRD), a popular UK research database also based on linked primary care records. METHODS: We describe the key features of the Discover database, including scope, architecture and governance; descriptive analyses compare the population demographics and chronic disease prevalences with those in CPRD. RESULTS: As of June 2019, Discover held records for a total of 2.3 million currently registered patients, or 95% of the NW London population; CPRD held records for over 11 million. The Discover population matches the overall age-sex distribution of the UK and CPRD but is more ethnically diverse. Most Discover chronic disease prevalences were comparable to the national rates. Unlike CPRD, Discover has identifiable care organisations and postcodes, allowing mapping and linkage to healthcare provider variables such as staffing, and includes contacts with social, community and mental health care. Discover also includes a consent-to-contact register of over 3000 volunteers to date for prospective studies. CONCLUSIONS: Like CPRD, Discover has been a number of years in the making, is a valuable research tool, and can serve as a model for other areas developing similar data warehouses.

Examining the 'gold standard': a comparative critical analysis of three consecutive decades of monopolar transurethral resection of the prostate (TURP) outcomes.

What's known on the subject? and What does the study add? Transurethral resection of the prostate (TURP) remains the dominant and definitive treatment for lower urinary tract symptoms due to benign prostatic hyperplasia (LUTS-BPH), but the widespread use of medical therapies (particularly monotherapies) for rapid symptom improvement has meant that the most common indication for TURP has shifted to moderate-severe medical therapy refractory LUTS to, coupled with abnormal objective parameters, or when complications arise. Patients undergoing TURP as part of contemporary randomised controlled trials are not older but have a larger preoperative prostate volume and reduced major morbidity compared with large cohort studies from successive past eras. Delayed surgery because of prolonged medical monotherapy may explain a higher reported failure to void rate, possibly because of negative impact on detrusor function from unrelieved obstruction. This study examined contemporary TURP for significant changes, specifically regarding prostate size, operative parameters, and outcomes, compared with two preceding decades. Electronic databases PubMed, EMBASE & Cochrane collaboration were searched for English literature on prospective randomized controlled trials, published between 1997 and 2007 using keywords "transurethral resection" and "prostate". Monopolar TURP (M-TURP) cohort data of each study were selectively pooled for analysis, weighting studies according to patient numbers. Where possible, pooled post-operative outcomes data were compared with two large cohort landmark studies of successive preceding decades. A total of 3470 patients from 67 studies were included. Mean patient age (67 years) was unchanged, while mean pre-operative prostate volume of 47.6 g was greater than previously reported. Mean resected prostate tissue (25.8 g) with a resection time of 38.5 minutes suggested improved resection efficiency. A statistically significantly reduced transfusion rate and increased urinary tract infection (UTI) rate were reported. Hospital stay (3.6 days) and initial catheterisation duration (2.5 days) were similar, but post-operative urinary retention rate was slightly higher (6.8%). Contemporary RCTs of M-TURP showed larger prostate volume, and reduced major morbidity, compared with large cohort studies from successive past eras. The higher reported failure to void rate, may possibly reflect worse detrusor function at time of TURP. Delaying surgery by prolonged medical monotherapy may compound this. Trials methodology in this area requires quality improvement and standardisation in future.

Nonelective excisional colorectal surgery in English National Health Service Trusts: a study of outcomes from Hospital Episode Statistics Data between 1996 and 2007.

BACKGROUND: Nonelective colorectal surgery is associated with substantial patient morbidity and mortality. This study sought to describe the practice of emergency colorectal surgery in the United Kingdom during an 11-year period using the Hospital Episode Statistics (HES) database. STUDY DESIGN: All nonelective admissions in patients undergoing 1 of 8 colorectal resectional procedures between 1996 and 2007 were included. Time trends, univariate, and multivariate mortality and length of stay outcomes were analyzed. RESULTS: A total of 102,236 major urgent/emergency procedures were performed in English National Health Service Trusts between April 1996 and March 2007. Thirty-day in-hospital postoperative mortality rates in patients with colorectal cancer and diverticular disease were 13.3% and 15.4%, respectively. The corresponding 1-year postoperative mortality was 34.7% and 22.6%. On multivariate analysis, benign diagnosis, advanced age, high comorbidity score, social deprivation, and specific procedure types were independent predictors of early and 1-year postoperative mortality (p < 0.001). Independent risk factors for extended hospital stay were advanced age, social deprivation, distal (compared with proximal) bowel resection, and a diagnosis of ulcerative colitis (p < 0.001). CONCLUSIONS: HES data suggest that in everyday practice, postoperative mortality among patients undergoing nonelective admission followed by colorectal resection is high. Additional investigation is required to assess the reliability of HES data for monitoring institutional variation in this context.
