Variation Between Hospitals in Outcomes and Costs of IBD Care: Results From the IBD Value Study.

BACKGROUND: Data on variation in outcomes and costs of the treatment of inflammatory bowel disease (IBD) can be used to identify areas for cost and quality improvement. It can also help healthcare providers learn from each other and strive for equity in care. We aimed to assess the variation in outcomes and costs of IBD care between hospitals. METHODS: We conducted a 12-month cohort study in 8 hospitals in the Netherlands. Patients with IBD who were treated with biologics and new small molecules were included. The percentage of variation in outcomes (following the International Consortium for Health Outcomes Measurement standard set) and costs attributable to the treating hospital were analyzed with intraclass correlation coefficients (ICCs) from case mix-adjusted (generalized) linear mixed models. RESULTS: We included 1010 patients (median age 45 years, 55% female). Clinicians reported high remission rates (83%), while patient-reported rates were lower (40%). During the 12-month follow-up, 5.2% of patients used prednisolone for more than 3 months. Hospital costs (outpatient, inpatient, and medication costs) were substantial (median: €8323 per 6 months), mainly attributed to advanced therapies (€6611). Most of the variation in outcomes and costs among patients could not be attributed to the treating hospitals, with ICCs typically between 0% and 2%. Instead, patient-level characteristics, often with ICCs above 50%, accounted for these variations. CONCLUSIONS: Variation in outcomes and costs cannot be used to differentiate between hospitals for quality of care. Future quality improvement initiatives should look at differences in structure and process measures of care and implement patient-level interventions to improve quality of IBD care.

Cost-Effectiveness Analysis of Increased Adalimumab Dose Intervals in Crohn's Disease Patients in Stable Remission: The Randomized Controlled LADI Trial.

BACKGROUND AND AIMS: We aimed to assess cost-effectiveness of increasing adalimumab dose intervals compared to the conventional dosing interval in patients with Crohn's disease [CD] in stable clinical and biochemical remission. DESIGN: We conducted a pragmatic, open-label, randomized controlled non-inferiority trial, comparing increased adalimumab intervals with the 2-weekly interval in adult CD patients in clinical remission. Quality of life was measured with the EQ-5D-5L. Costs were measured from a societal perspective. Results are shown as differences and incremental net monetary benefit [iNMB] at relevant willingness to accept [WTA] levels. RESULTS: We randomized 174 patients to the intervention [n = 113] and control [n = 61] groups. No difference was found in utility (difference: -0.017, 95% confidence interval [-0.044; 0.004]) and total costs (-€943, [-€2226; €1367]) over the 48-week study period between the two groups. Medication costs per patient were lower (-€2545, [-€2780; -€2192]) in the intervention group, but non-medication healthcare (+€474, [+€149; +€952]) and patient costs (+€365 [+€92; €1058]) were higher. Cost-utility analysis showed that the iNMB was €594 [-€2099; €2050], €69 [-€2908; €1965] and -€455 [-€4,096; €1984] at WTA levels of €20 000, €50 000 and €80 000, respectively. Increasing adalimumab dose intervals was more likely to be cost-effective at WTA levels below €53 960 per quality-adjusted life year. Above €53 960 continuing the conventional dose interval was more likely to be cost-effective. CONCLUSION: When the loss of a quality-adjusted life year is valued at less than €53 960, increasing the adalimumab dose interval is a cost-effective strategy in CD patients in stable clinical and biochemical remission.

[Gastric perforation in Eastern European economic migrants]. / Maagperforatie bij Oost-Europese arbeidsmigranten.

The general prevalence of perforated peptic ulcers is decreasing and they are, therefore, more likely to be missed. In our hospital, Eastern European migrants are overrepresented in the population of patients with perforated gastric peptic ulcers; due to a higher prevalence of Helicobacter pylori in Eastern Europe, they have a higher chance of developing gastric peptic ulcers than patients of Dutch origin. Treatment is hampered by the language barrier and low compliance rates, with patients often leaving hospital against medical advice and not showing up for follow-up appointments. These patients should, therefore, be informed by an interpreter, so that they are well educated about the disease and its treatment. Furthermore, we advise determination of the presence of H. pylori in these patients either during or directly after surgery, and, if necessary, empirical eradication of the bacteria.

Pancreatitis-associated protein has no additional value as a marker of disease activity in a real-life cohort of IBD patients.

BACKGROUND AND AIM: Monitoring of mucosal inflammation in inflammatory bowel disease (IBD) is of major importance. New noninvasive markers for intestinal inflammation are needed. Previous studies have reported that pancreatitis-associated protein (PAP) correlates with clinical activity in IBD subgroups. Our aim was to investigate the correlation of serum and fecal PAP with clinical and biochemical parameters of disease activity in a real-life IBD cohort. PATIENTS AND METHODS: Two hundred and five consecutive IBD patients were enrolled. Clinical disease activity was scored by the Harvey-Bradshaw Index or the Simple Clinical Colitis Activity Index; also, C-reactive protein (CRP), erythrocyte sedimentation rate, and fecal calprotectin were determined. As surrogate for endoscopy, a combination score of clinical indices with CRP or calprotectin was used to define active disease. Fecal and serum PAP were measured by ELISA. RESULTS: The median serum and fecal PAP did not differ in Crohn's disease (CD) or ulcerative colitis (UC) patients with active compared with inactive disease according to clinical activity indices. Defining active disease by a combination score of Harvey-Bradshaw Index of more than 4 and CRP of more than 5 mg/l or calprotectin more than 250 µg/g, serum PAP (P=0.01), but not fecal PAP (P=0.32), was significantly higher in active than inactive CD patients. Area under the curve of the corresponding receiver operating curve (ROC) was 0.64. No differences were found in serum or fecal PAP levels using the combination score for active disease in UC. CONCLUSION: Serum but not fecal PAP was higher in active compared with nonactive CD and may reflect mucosal inflammation in CD, but not in UC. However, the accuracy of serum PAP for the diagnosis of active disease was poor, and therefore, serum PAP does not seem to have additional value compared with the current noninvasive markers.
