A chronic care model significantly decreases costs and healthcare utilisation in patients with inflammatory bowel disease

INTRODUCTION Inflammatory bowel disease (IBD) is a chronic condition, yet the model of care is often reactive. We sought to examine whether a formal IBD service (IBDS) reduced inpatient healthcare utilisation or lowered costs for inpatient care. MATERIAL AND METHODS With protocols, routine nurse phone follow-up a help-line, more proactive care was delivered, with many symptoms and concerns dealt with prior to routine presentation. Over two five month periods before (2007/8) and after (2009/10) introducing a formal IBDS two discrete cohorts of admitted IBD patients were identified at a single centre. Each patient was assigned five contemporaneously admitted, age and gender matched controls. Inpatient healthcare utilisation was compared between patients and controls and disease-specific factors amongst the two IBD cohorts. RESULTS The initial audit captured 102 admitted IBD patients (510 controls, median age 44 years, 57% female); the second audit 95 patients (475 controls, median age 46 years, 45.3% female). In 2009/10, the number of admissions was lower in IBD patients than in controls (mean 1.53+/-1.03 vs. 2.54+/-2.35; p<0.0001). This contrasts with the first audit, where IBD patients had more admissions than controls. Following IBDS introduction, the mean total cost of inpatient care was lower for IBD patients than controls (US

In addition, patients known to a specialist gastroenterologist (GE) and the IBD Service tended to have the lowest mean number of admissions (GE and IBDS 1.14 (+/-0.36) vs. no GE/IBDS 1.64 (+/-1.25)). CONCLUSIONS Healthcare utilisation and disease burden in IBD decreased significantly since introducing an IBDS. These data suggest that proactive management improved outcomes. Contact with a gastroenterologist and IBDS seemed to give best results.

Body composition is poorly studied in inflammatory bowel disease (IBD). Sarcopenia describes a loss of muscle mass and strength.

BACKGROUND Smoking increases CD risk. The aim was to determine if smoking cessation at, prior to, or following, CD diagnosis affects medication use, disease phenotypic progression and/or surgery. METHODS Data on CD patients with disease for ≥5 yrs were collected retrospectively including the Montreal classification, smoking history, CD-related abdominal surgeries, family history, medication use and disease behaviour at diagnosis and the time when the disease behaviour changed. RESULTS 1115 patients were included across six sites (mean follow-up-16.6 yrs). More non-smokers were male (p=0.047) with A1 (p<0.0001), L4 (p=0.028) and perianal (p=0.03) disease. Non-smokers more frequently received anti-TNF agents (p=0.049). (p=0.017: OR 2.5 95%CI 1.18-5.16) and those who ceased smoking prior to diagnosis (p=0.045: OR 2.3 95%CI 1.02-5.21) progressed to complicated (B2/B3) disease as compared to those quitting at diagnosis. Patients with uncomplicated terminal ileal disease at diagnosis more frequently developed B2/B3 disease than isolated colonic CD (p<0.0001). B2/B3 disease was more frequent with perianal disease (p<0.0001) and if i.v. steroids (p=0.004) or immunosuppressants (p<0.0001) were used. 49.3% (558/1115) of patients required at least one intestinal surgery. More smokers had a 2nd surgical resection than patients who quit at, or before, the 1st resection and non-smokers (p=0.044: HR=1.39 95%CI 1.01-1.91). Patients smoking >3 cigarettes/day had an increased risk of developing B2/B3 disease (p=0.012: OR 3.8 95%CI 1.27-11.17). CONCLUSION Progression to B2/B3 disease and surgery is reduced by smoking cessation. All CD patients regardless of when they were diagnosed, or how many surgeries, should be strongly encouraged to cease smoking.

BACKGROUND Crohns disease (CD) exhibits significant clinical heterogeneity. Classification systems attempt to describe this; however, their utility and reliability depends on inter-observer agreement (IOA). We therefore sought to evaluate IOA using the Montreal Classification (MC). METHODS De-identified clinical records of 35 CD patients from 6 Australian IBD centres were presented to 13 expert practitioners from 8 Australia and New Zealand Inflammatory Bowel Disease Consortium (ANZIBDC) centres. Practitioners classified the cases using MC and forwarded data for central blinded analysis. IOA on smoking and medications was also tested. Kappa statistics, with pre-specified outcomes of κ>0.8 excellent; 0.61-0.8 good; 0.41-0.6 moderate and ≤0.4 poor, were used. RESULTS 97% of study cases had colonoscopy reports, however, only 31% had undergone a complete set of diagnostic investigations (colonoscopy, histology, SB imaging). At diagnosis, IOA was excellent for age, κ=0.84; good for disease location, κ=0.73; only moderate for upper GI disease (κ=0.57) and disease behaviour, κ=0.54; and good for the presence of perianal disease, κ=0.6. At last follow-up, IOA was good for location, κ=0.68; only moderate for upper GI disease (κ=0.43) and disease behaviour, κ=0.46; but excellent for the presence/absence of perianal disease, κ=0.88. IOA for immunosuppressant use ever and presence of stricture were both good (κ=0.79 and 0.64 respectively). CONCLUSION IOA using MC is generally good; however some areas are less consistent than others. Omissions and inaccuracies reduce the value of clinical data when comparing cohorts across different centres, and may impair the ability to translate genetic discoveries into clinical practice.
