“…Furthermore, there is a risk of misclassification, to identify CD and UC patients, as we relied on the accuracy of the ICD-10 coding in the NPR. The reliability and validity of the diagnosis registration in the NPR has been assessed to be good, however there have not been any studies that explicitly validate the registration of CD and UC diagnosis codes [18][19][20]. The study aimed to prevent the potential of confounding by direct matching on age and gender, however as in all observational studies without random allocation to the exposure groups, e.g., individuals with and without IBD in this study, unmeasured confounding may still affect the validity.…”

Objective: There is little information on cost-of-illness among patients diagnosed with Crohn's disease (CD) and ulcerative colitis (UC) in Denmark. The objective of this study was to estimate the average 5year societal costs attributable to CD or UC patients in Denmark with incidence in 2003-2015, including costs related to health care, prescription medicine, home care and production loss. Materials and methods: A national register-based, cost-of-illness study was conducted using an incidence-based approach to estimate societal costs. Incident patients with CD or UC were identified in the National Patient Registry and matched with a non-IBD control from the general population on age and sex. Attributable costs were estimated applying a difference-indifference approach, where the total costs among individuals in the control group were subtracted from the total costs among patients. Results: CD and UC incidence fluctuated but was approximately 14 and 31 per 100,000 person years, respectively. The average attributable costs were highest the first year after diagnosis, with costs equalling e12,919 per CD patient and e6,501 per UC patient. Hospital admission accounted for 36% in the CD population and 31% in the UC population, the first year after diagnosis. Production loss exceeded all other costs the third-year after diagnosis (CD population: 52%; UC population: 83%). Conclusions: We found that the societal costs attributable to incident CD and UC patients are substantial compared with the general population, primarily consisting of hospital admission costs and production loss. Appropriate treatment at the right time may be beneficial from a societal perspective.

BackgroundPneumonia is a frequent lung infection and a serious illness, which is often diagnosed among patients hospitalized with acute exacerbations of COPD. The aim of this study was to estimate the attributable costs due to pneumonia among patients hospitalized with pneumonia compared to a matched general population control group without pneumonia hospitalization.MethodsThis study includes citizens older than 18 years from three municipalities (n=142,344). Based on national registers and municipal data, the health and social care costs of pneumonia in the second half of 2013 are estimated and compared with propensity score-matched population controls.ResultsThe average health care costs of 383 patients hospitalized with pneumonia in the second half of 2013 were US$34,561 per patient. Among pneumonia patients with COPD, the costs were US$35,022. The attributable costs of patients with pneumonia compared to the population control group for the 6-month period were US$24,155 per case. Overall, the attributable costs for the 383 pneumonia cases amounted to US$9.25 million. Subgroup analyses showed that costs increased with age. The attributable costs due to pneumonia were highest among the 18–59-year-old and the 70–79-year-old patients. This difference is likely to reflect an increased risk of mortality among the pneumonia patients. Men have higher costs than women in the pneumonia group.ConclusionThe costs of pneumonia are considerable. In three Danish municipalities, the attributable costs due to pneumonia were US$24,155 per case or US$64,992 per 1,000 inhabitants in the second half of 2013. Similar high health care and social care costs were found for pneumonia patients with COPD – the largest group having pneumonia episodes. The municipalities are responsible for 49% of the costs, while a closer focus on the prevention of pneumonia may be advisable, eg, starting with citizens having COPD.

“…The National Patient Register16 includes information on admissions and outpatient visits from all somatic hospital wards in Denmark. These are assigned a DRG-tariff, according to the Danish DRG-system17 as a proxy for costs. The Danish National Prescription Register18 provides information on all prescription pharmaceuticals purchased at Danish pharmacies.…”
