Sources of diagnostic delay for people with Crohn's disease and ulcerative colitis: Qualitative research study. PLoS One 2024; 19:e0301672. [PMID: 38857292 PMCID: PMC11164383 DOI: 10.1371/journal.pone.0301672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 03/20/2024] [Indexed: 06/12/2024] Open
Abstract
OBJECTIVE An improved understanding of the causes and experience of diagnostic delay in Inflammatory Bowel Disease (IBD). METHODS Framework analysis of semi-structured interviews with 20 adults with IBD. RESULTS Participants' prior knowledge of normal bowel function/IBD was limited. Symptoms were sometimes misattributed to mild/transient conditions or normalised until intolerable. Family pressures, work, education, mistrust of doctors, fear and embarrassment could exacerbate delays. Poor availability of face-to-face appointments deterred people from seeing a GP. Patients feared that by the time they got to see their GP, their symptoms would have resolved. Patients instead self-managed symptoms, but often regretted not seeking help earlier. Limited time in consultations, language barriers, embarrassment, and delays in test results subsequently delayed specialist referrals. GPs misattributed symptoms to other conditions due to atypical or non-specific presentations, leading to reduced trust in health systems. Patients complained of poor communication, delays in accessing test results, appointments, and onward referrals-all associated with clinical deterioration. GPs were sometimes unable to 'fast-track' patients into specialist care. Consultations and endoscopies were often difficult experiences for patients, especially for non-English speakers who are also less likely to receive information on mental health support and the practicalities of living with IBD. CONCLUSIONS The framework analysis demonstrates delay in the diagnosis of IBD at each stage of the patient journey. RECOMMENDATIONS Greater awareness of IBD amongst the general population would facilitate presentation to healthcare services through symptom recognition by individuals and community advice. Greater awareness in primary care would help ensure IBD is included in differential diagnosis. In secondary care, greater attention to the wider needs of patients is needed-beyond diagnosis and treatment. All clinicians should consider atypical presentations and the fluctuating nature of IBD. Diagnostic overshadowing is a significant risk-where other diagnoses are already in play the risk of delay is considerable.

Jayasooriya N, Saxena S, Blackwell J, Bottle A, Creese H, Petersen I, Pollok RCG. Associations between prior healthcare use, time to diagnosis, and clinical outcomes in inflammatory bowel disease: a nationally representative population-based cohort study. BMJ Open Gastroenterol 2024; 11:e001371. [PMID: 38802264 PMCID: PMC11131120 DOI: 10.1136/bmjgast-2024-001371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2024] [Accepted: 04/23/2024] [Indexed: 05/29/2024] Open
Abstract
BACKGROUND Timely diagnosis and treatment of inflammatory bowel disease (IBD) may improve clinical outcomes. OBJECTIVE Examine associations between time to diagnosis, patterns of prior healthcare use, and clinical outcomes in IBD. DESIGN Using the Clinical Practice Research Datalink we identified incident cases of Crohn's disease (CD) and ulcerative colitis (UC), diagnosed between January 2003 and May 2016, with a first primary care gastrointestinal consultation during the 3-year period prior to IBD diagnosis. We used multivariable Cox regression to examine the association of primary care consultation frequency (n=1, 2, >2), annual consultation intensity, hospitalisations for gastrointestinal symptoms, and time to diagnosis with a range of key clinical outcomes following diagnosis. RESULTS We identified 2645 incident IBD cases (CD: 782; UC: 1863). For CD, >2 consultations were associated with intestinal surgery (adjusted HR (aHR)=2.22, 95% CI 1.45 to 3.39) and subsequent CD-related hospitalisation (aHR=1.80, 95% CI 1.29 to 2.50). For UC, >2 consultations were associated with corticosteroid dependency (aHR=1.76, 95% CI 1.28 to 2.41), immunomodulator use (aHR=1.68, 95% CI 1.24 to 2.26), UC-related hospitalisation (aHR=1.43, 95% CI 1.05 to 1.95) and colectomy (aHR=2.01, 95% CI 1.22 to 3.27). For CD, hospitalisation prior to diagnosis was associated with CD-related hospitalisation (aHR=1.30, 95% CI 1.01 to 1.68) and intestinal surgery (aHR=1.71, 95% CI 1.13 to 2.58); for UC, it was associated with immunomodulator use (aHR=1.42, 95% CI 1.11 to 1.81), UC-related hospitalisation (aHR=1.36, 95% CI 1.06 to 1.95) and colectomy (aHR=1.54, 95% CI 1.01 to 2.34). For CD, consultation intensity in the year before diagnosis was associated with CD-related hospitalisation (aHR=1.19, 95% CI 1.12 to 1.28) and intestinal surgery (aHR=1.13, 95% CI 1.03 to 1.23); for UC, it was associated with corticosteroid use (aHR=1.08, 95% CI 1.04 to 1.13), corticosteroid dependency (aHR=1.05, 95% CI 1.00 to 1.11), and UC-related hospitalisation (aHR=1.12, 95% CI 1.03 to 1.21). For CD, time to diagnosis was associated with risk of CD-related hospitalisation (aHR=1.03, 95% CI 1.01 to 1.68); for UC, it was associated with reduced risk of UC-related hospitalisation (aHR=0.83, 95% CI 0.70 to 0.98) and colectomy (aHR=0.59, 95% CI 0.43 to 0.80). CONCLUSION Electronic records contain valuable information about patterns of healthcare use that can be used to expedite timely diagnosis and identify aggressive forms of IBD.

Abstract
BACKGROUND Kidney complications are common in patients with long-standing inflammatory bowel disease (IBD). Whether kidney complications, defined as low estimated glomerular filtration rate (eGFR), may predispose to later IBD is unknown. METHODS We analyzed the association between eGFR and the risk of being subsequently diagnosed with IBD among 1 612 160 adults from Stockholm. The exposure was categories of eGFR, with 90 to 104 mL/min/1.73 m2 as the reference. Cox regression models were used to investigate the association between eGFR, IBD, and IBD subtypes. Subgroup analyses included age strata, sex, education, and comorbidities. To explore the possibility of detection bias or reverse causation, we estimated IBD hazard ratios (HRs) after excluding cases and individuals censored during early years of follow-up. RESULTS During a median of 9 years of follow-up, we detected 9663 cases of IBD (3299 Crohn's disease, 5072 ulcerative colitis, 1292 IBD unclassified). Lower eGFR levels were associated with higher IBD risk (for eGFR 30-59 mL/min/1.73 m2: adjusted HR, 1.15; 95% confidence interval [CI], 1.01-1.33; and for eGFR <30 mL/min/1.73 m2: adjusted HR, 1.65; 95% CI, 1.16-2.37). This association was stronger in magnitude for Crohn's disease (for eGFR 30-59 mL/min/1.73 m2: HR, 1.33, 95% CI, 1.04-1.72; and for eGFR <30 mL/min/1.73 m2: HR, 2.25; 95% CI, 1.26-3.99). Results were consistent across strata of age, comorbidities, and attained education but suggested the association between eGFR and IBD to be stronger in women (P for interaction <.05). Results attenuated but were robust to exclusion of early IBD cases. CONCLUSIONS We observed an association between reduced eGFR and the risk of developing IBD, which was stronger in magnitude for Crohn's disease.

The Time to Inflammatory Bowel Disease Diagnosis for Patients Presenting with Abdominal Symptoms in Primary Care and its Association with Emergency Hospital Admissions and Surgery: A Retrospective Cohort Study. Inflamm Bowel Dis 2024:izae057. [PMID: 38563769 DOI: 10.1093/ibd/izae057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Indexed: 04/04/2024]
Abstract
BACKGROUND Patients with inflammatory bowel disease (IBD) presenting to primary care may experience diagnostic delays. We aimed to evaluate this and assess whether time to diagnosis is associated with clinical outcomes. METHODS A retrospective cohort study using English primary care data from January 1, 2010, to December 31, 2019, linked to hospital admission data was undertaken. Patients were followed from the first IBD-related presentation in primary care to IBD diagnosis. Associations of time to diagnosis exceeding a year were assessed using a Robust Poisson regression model. Associations between time to diagnosis and IBD-related emergency hospital admissions and surgery were assessed using Poisson and Cox proportional hazards models, respectively. RESULTS Of 28 092 IBD patients, 60% had ulcerative colitis (UC) and 40% had Crohn's disease (CD). The median age was 43 (interquartile range, 30-58) years and 51.9% were female. Median time to diagnosis was 15.6 (interquartile range, 4.3-28.1) months. Factors associated with more than a year to diagnosis included female sex (adjusted risk ratio [aRR], 1.23; 95% CI, 1.21-1.26), older age (aRR, 1.05; 95% CI, 1.01-1.10; comparing >70 years of age with 18-30 years of age), obesity (aRR, 1.03; 95% CI, 1.00-1.06), smoking (aRR, 1.05; 95% CI, 1.02-1.08), CD compared with UC (aRR, 1.13; 95% CI, 1.11-1.16), and a fecal calprotectin over 500 μg/g (aRR, 0.89; 95% CI, 0.82-0.95). The highest quartile of time to diagnosis compared with the lowest was associated with IBD-related emergency admissions (incidence rate ratio, 1.06; 95% CI, 1.01-1.11). CONCLUSION Longer times to IBD diagnoses were associated with being female, advanced age, obesity, smoking, and Crohn's disease. More IBD-related emergency admissions were observed in patients with a prolonged time to diagnosis.

Abstract
BACKGROUND Female gender could be a cause of diagnostic delay in inflammatory bowel disease (IBD). The aim of this study was to investigate the diagnostic delay in women vs men and potential causes. METHODS This multicenter cohort study included 190 patients with recent diagnosis of IBD (disease duration <7 months). Reconstruction of the clinical presentation and diagnostic process was carried out in conjunction with the semistructured patient interview, review, and electronic medical records. RESULTS The median time from symptom onset to IBD diagnosis was longer in women than in men: 12.6 (interquartile range, 3.7-31) vs 4.5 (2.2-9.8) months for Crohn's disease (CD; P = .008) and 6.1 (3-11.2) vs 2.7 (1.5-5.6) months for ulcerative colitis (UC; P = .008). Sex was an independent variable related to the time to IBD diagnosis in Cox regression analysis. The clinical presentation of IBD was similar in both sexes. Women had a higher percentage of misdiagnosis than men (CD, odds ratio [OR], 3.9; 95% confidence [CI], 1.5-9.9; UC, OR 3.0; 95% CI, 1.2-7.4). Gender inequities in misdiagnosis were found at all levels of the health system (emergency department, OR 2.4; 95% CI, 1.1-5.1; primary care, OR 2.5; 95% CI, 1.3-4.7; gastroenterology secondary care, OR 3.2; 95% CI, 1.2-8.4; and hospital admission, OR 4.3; 95% CI, 1.1-16.9). CONCLUSIONS There is a longer diagnostic delay in women than in men for both CD and UC due to a drawn-out evaluation of women, with a higher number of misdiagnoses at all levels of the health care system.

Abstract
Background Delayed diagnosis is a major barrier to the effective management of Crohn's disease (CD). Several studies have investigated factors responsible for delays in diagnosis, but no meta-analyses have systematically assessed the impact of these factors. Aim To assess the impact of various factors on the delayed diagnosis of CD. Methods PubMed, EMBASE, and Web of Science databases were searched to identify observational studies published before April 2022 that assessed factors associated with delays in CD diagnosis. Further, we excluded review articles, case reports, or commentaries without original data. We pooled effect siee distinct samples. The assessment of study quality was performed utilizing the Newcastle-Ottawa Scale, while the presence of between-study heterogeneity was investigated. For a visual appraisal of potential publication bias, a funnel plot was employed. The study protocol was registered with PROSPERO, CRD42022322251. Results A total of 18 studies were included in the paper, covering 13 countries. The study sample consisted of 9669 cases. Ileal CD (OR = 1.46, 95 % CI = 1.21-1.76), smoking at the time of diagnosis (OR = 1.19, 95 % CI = 1.02-1.38), and use of NSAIDs (OR = 1.34, 95 % CI = 1.04-1.72) were significantly associated with a delay in CD diagnosis. However, no significant associations were observed between diagnostic delay and sex, age, endoscopic ileocolonoscopy, or diarrhea. Funnel plot analysis, indicating potential risks of publication bias, suggested the existence of unpublished or unreported study findings. Conclusion The findings suggest that ileal CD, use of NSAIDs, and smoking are risk factors for the delayed diagnosis of CD. Enhancing education of patients and primary care providers about these factors is warranted.

Abstract
Background and aims Healthcare quality improvement (QI) is the systematic process to continuously improve the quality of care and outcomes for patients. The landmark Inflammatory Bowel Disease (IBD) UK National Audits provided a means to measure the variation in care, highlighting the need to define the standards of excellence in IBD care. Through a consensus approach, we aimed to establish key performance indicators (KPIs), providing reliable benchmarks for IBD care delivery in UK. Methods KPIs that measure critical aspects of a patient journey within an IBD service were identified though stakeholder meetings. A two-stage Delphi consensus was then conducted. The first involved a multidisciplinary team of IBD clinicians and patients to refine definitions and methodology. The second stage assessed feasibility and utility of the proposed QI process by surveying gastroenterology services across UK. Results First, the four proposed KPIs were refined and included time from primary care referral to diagnosis in secondary care, time to treatment recommendation following a diagnosis, appropriate use of steroids and advanced therapies prescreening and assessment. Second, the Delphi consensus reported >85% agreement on the feasibility of local adoption of the QI process and >75% agreement on the utility of benchmarking of the KPIs. Conclusions Through a structured approach, we propose quantifiable KPIs for benchmarking to improve and reduce the individual variation in IBD care across the UK.

Abstract
BACKGROUND Sleep dysregulation has been linked to gastrointestinal dysfunction and inflammation. AIMS To explore the associations between sleep duration, daytime napping and inflammatory bowel disease (IBD), Crohn's disease (CD) and ulcerative colitis (UC). METHODS Exposure information was obtained from the baseline questionnaire. Sleep duration was coded as continuous and categorical (≤5, 6, 7, 8, ≥9 h/day) variables. Daytime napping was defined as yes (sometimes/usually) and no (never/rarely). Incident IBD cases were defined from primary care and hospital inpatient records. Polygenic risk scores (PRS) for the outcomes were constructed and categorised into low, intermediate and high risk. Hazard ratio (HR) and confidence interval (CI) were estimated using Cox proportional hazard regression. RESULTS The analysis included 2604 incident IBD cases (806 CD and 1798 UC) with a median follow-up of 12.0 years. Comparing sleep duration ≤5 with 7 h/day, the HR of IBD, CD and UC was 1.36 (95% CI, 1.17-1.59), 1.53 (95% CI, 1.17-2.00) and 1.29 (95% CI, 1.07-1.56), respectively. Comparing participants with and without daytime napping, the HR of IBD, CD and UC was 1.13 (95% CI, 1.05-1.23), 1.25 (95% CI, 1.08-1.44) and 1.09 (95% CI, 0.90-1.20), respectively. No interaction of sleep duration and daytime napping with PRS was detected. However, the associations appeared stronger in individuals with high rather than low PRS. CONCLUSIONS This study reveals positive associations between short sleep duration and daytime napping and IBD risk.

Systematic review with meta-analysis: Time to diagnosis and the impact of delayed diagnosis on clinical outcomes in inflammatory bowel disease. Aliment Pharmacol Ther 2023; 57:635-652. [PMID: 36627691 DOI: 10.1111/apt.17370] [Citation(s) in RCA: 27] [Impact Index Per Article: 27.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 09/29/2022] [Accepted: 12/10/2022] [Indexed: 01/12/2023]
Abstract
BACKGROUND The impact of diagnostic delay on the clinical course of inflammatory bowel disease (IBD) remains uncertain. AIM To perform a systematic review of time to diagnosis and the impact of delayed diagnosis on clinical outcomes in Crohn's disease (CD) and ulcerative colitis (UC). METHODS We searched EMBASE and Medline from inception to 30th November 2022 for studies reporting diagnostic interval, from symptom onset to IBD diagnosis. We calculated the median, interquartile range (IQR) and pooled weighted median, of median diagnostic intervals of eligible studies. We defined delayed diagnosis as individuals above the 75th centile of longest time to diagnosis in each study. Using random effects meta-analysis, we pooled odds ratios (ORs) with 95% confidence intervals (CI) for studies reporting clinical outcomes, according to delayed diagnosis. RESULTS One hundred and one studies representing 112,194 patients with IBD (CD = 59,359; UC = 52,835) met inclusion criteria. The median of median times to diagnosis was 8.0 (IQR: 5.0-15.2) and 3.7 months (IQR: 2.0-6.7) in CD and UC, respectively. In high-income countries, this was 6.2 (IQR: 5.0-12.3) and 3.2 months (IQR: 2.2-5.3), compared with 11.7 (IQR: 8.3-18.0) and 7.8 months (IQR: 5.2-21.8) in low-middle-income, countries, for CD and UC respectively. The pooled weighted median was 7.0 (95% CI: 3.0-26.4) and 4.6 (95% CI: 1.0-96.0) months, for CD and UC respectively. Eleven studies, representing 6164 patients (CD = 4858; UC = 1306), were included in the meta-analysis that examined the impact of diagnostic delay on clinical outcomes. In CD, delayed diagnosis was associated with higher odds of stricturing (OR = 1.88; CI: 1.35-2.62), penetrating disease (OR = 1.64; CI: 1.21-2.20) and intestinal surgery (OR = 2.24; CI: 1.57-3.19). In UC, delayed diagnosis was associated with higher odds of colectomy (OR = 4.13; CI: 1.04-16.40). CONCLUSION Delayed diagnosis is associated with disease progression in CD, and intestinal surgery in both CD and UC. Strategies are needed to achieve earlier diagnosis of IBD.

Abstract
BACKGROUND The extent of diagnostic delay in inflammatory bowel disease (IBD) is incompletely understood. We aimed to understand the extent of diagnostic delay of IBD in adults and identify associations between patient or healthcare characteristics and length of delay. METHODS Articles were sourced from EMBASE, Medline and CINAHL from inception to April 2021. Inclusion criteria were adult cohorts (18 ≥ years old) reporting median time periods between onset of symptoms for Crohn's disease (CD), ulcerative colitis (UC) or IBD (i.e. CD and UC together) and a final diagnosis (diagnostic delay). Narrative synthesis was used to examine the extent of diagnostic delay and characteristics associated with delay. Sensitivity analysis was applied by the removal of outliers. RESULTS Thirty-one articles reporting median diagnostic delay for IBD, CD or UC were included. After sensitivity analysis, the majority of IBD studies (7 of 8) reported a median delay of between 2 and 5.3 months. From the studies examining median delay in UC, three-quarters (12 of 16) reported a delay between 2 and 6 months. In contrast, three-quarters of the CD studies (17 of 23) reported a delay of between 2 and 12 months. No characteristic had been examined enough to understand their role in diagnostic delay in these populations. CONCLUSIONS This systematic review provides robust insight into the extent of diagnostic delay in IBD and suggests further intervention is needed to reduce delay in CD particularly. Furthermore, our findings provide a benchmark value range for diagnostic delay, which such future work can be measured against.

Abstract
Despite huge advances in understanding the molecular basis of IBD, clinical management has continued to rely on a "trial and error" approach. In addition, a therapeutic ceiling has emerged whereby even the most effective interventions are only beneficial for approximately 30% of patients. Consequently, several tools have been developed to aid stratification and guide treatment-decisions. We review the potential application for many of these precision medicine approaches, which are now almost within reach. We highlight the importance of early action (and avoiding inaction) to ensure the best outcomes for patients and how combining early action with precision tools will likely ensure the right treatment is delivered at the right time and place for each individual person living with IBD. The lack of clinical impact to date from precision medicine, despite much hype and investment, should be tempered with the knowledge that clinical translation can take a long time, and many promising breakthroughs might be ready for clinical implementation in the near future. We discuss some of the remaining challenges and barriers to overcome for clinical adoption. We also highlight that early recognition, early diagnosis, early stratification, and early intervention go hand in hand with precision medicine tools. It is the combination of these approaches that offer the greatest opportunity to finally deliver on the promise of precision medicine in IBD.

Abstract
To explore the status of diagnostic delay and to clarify its potentially influencing factors in patients with chronic obstructive pulmonary disease (COPD). A cross-sectional study was conducted in a Chinese tertiary hospital between July 2019 and February 2020. A total of 408 eligible outpatients with COPD were recruited, and relevant data were collected in the form of questionnaires. Diagnostic delay was compared among different characteristics using the Wilcoxon test and Kruskal–Wallis H test. Multivariable linear regression analysis was performed to determine the factors related to diagnostic delay. The median (interquartile range [IQR]) duration of diagnostic delay was 230 (50–720) days. The proportions of COPD patients who chose tertiary, secondary, and first-level hospitals for the first visit were 53.7%, 29.9%, and 16.4%, respectively. Additionally, the proportions of patients who underwent pulmonary function tests for the first visit in tertiary, secondary, and first-level hospitals were 74.0%, 24.6%, and 1.5% (p < 0.001), respectively. In terms of characteristics related to diagnostic delay, there was a significant difference in residence, resident manner, COPD assessment test (CAT) score, modified Medical British Research Council (mMRC) dyspnea scale, age, forced expiratory volume in one second (FEV1) % predicted, and years of education (all p < 0.01). Linear regression analysis showed that significant predictors of diagnostic delay included FEV1% predicted (p < 0.05), resident manner (p < 0.001), and years of education (p < 0.01). Our study indicates that varying degrees of diagnostic delay may exist in patients with COPD. Measures are needed to intervene in the potential factors associated with diagnostic delay.

Abstract
Inflammatory bowel diseases (IBDs), including Crohn's disease and ulcerative colitis, are chronic, progressive, immune-mediated diseases of adults and children that have no cure. IBD can cause significant morbidity and lead to complications such as strictures, fistulas, infections, and cancer. In children, IBD can also result in growth impairment and pubertal delays. IBD is highly heterogenous, with severity ranging from mild to severe and symptoms ranging from mild to debilitating. Delay in IBD diagnosis, especially in Crohn's disease, is common and associated with adverse outcomes. Early diagnosis and prompt institution of treatment are the cornerstones for improving outcomes and maximizing health. Early diagnosis requires a low threshold of suspicion and red flags to guide early specialist referral at the primary provider level. Although the armamentarium of IBD medications is growing, many patients will not respond to treatment, and the selection of first-line therapy is critical. Risk stratification of disease severity, based on clinical, demographic, and serologic markers, can help guide selection of first-line therapy. Clinical decision support tools, genomics, and other biomarkers of response to therapy and risk of adverse events are the future of personalized medicine. After starting appropriate therapy, it is important to confirm remission using objective end points (treat to target) with continued control of inflammation with adjustment of therapy using surrogate biomarkers (tight control). Lastly, IBD therapy extends far beyond medications, and other aspects of the overall health and wellbeing of the patient are critical. These include preventive health, nutrition, and psychobehavioral support addressing patients' concerns around complementary therapy and medication adherence, prevention of disability, and ensuring open communication.
