Assessment of disease specific knowledge and health-related quality of life among United States military veterans with inflammatory bowel disease

Abstract

AIM:To evaluate the association between patient disease knowledge of inflammatory bowel disease (IBD) and health related quality of life (HRQoL) and identify patient and disease related predictors of patient knowledge of IBD. METHODS:We performed a cross-sectional study of IBD patients with an established diagnosis of IBD longer than 3 mo prior to enrollment. The Crohn's and colitis knowledge score (CCKNOW) and short inflammatory bowel disease questionnaire (SIBDQ) were selfadministered to assess patient knowledge of IBD and HRQoL, respectively. Demographic and disease characteristics were abstracted from the electronic medical record. The correlation between CCKNOW and SIBDQ scores was assessed by a linear regression model. Associations of patient knowledge and the variables of interest were calculated using ANOVA. RESULTS:A total of 101 patients were recruited. Caucasian race, younger age at diagnosis, and having Prospective Study ORIGINAL ARTICLEa college or post-graduate degree were significantly associated with higher CCKNOW scores. Patients with CD had higher CCKNOW scores compared to patients with ulcerative colitis and inflammatory bowel disease type unclassified, P < 0.01. There was no significant correlation between overall CCKNOW and SIBDQ scores (r 2 = 0.34, P = 0.13). The knowledge sub-domain of diet in CCKNOW was negatively correlated with HRQoL (r 2 = 0.69, P < 0.01).CONCLUSION: IBD diagnosis at a younger age in addition to Caucasian race and higher education were significantly associated with higher knowledge about IBD. However, patient knowledge of IBD was not correlated with HRQoL. Further studies are required to study the effect of patient knowledge of IBD on other clinical outcomes.

Assessment of disease‐related knowledge and possible factors associated with the knowledge level among Chilean patients with inflammatory bowel disease

“…The highest mean CCKNOW scores that have been published are 12Á4 in UC and 12Á6 in CD patients, and these scores occurred in patients who are members of an IBD association (Eaden et al 1999). Our results revealed that the patients with UC exhibited lower CCKNOW scores than the patients with CD, and similar results have been reported in other studies (Subasinghe et al 2010, Hou et al 2015, Yoo et al 2015. This difference might be explained by the fact that patients with CD have more hospitalisations and surgeries than patients with UC (Simian et al 2014, Niewiadomski et al 2015, and thus, they have more opportunities to share information with specialists.…”

“…In our study, the patients with the disease for less than one year exhibited lower disease-related knowledge than patients with longer histories of IBD. This result is similar to those of previous studies (Hou et al 2015, Yoo et al 2015 but differs from other studies that did not find any association between the disease duration and patient knowledge (Eaden et al 1999, Rezailashkajani et al 2006.…”

Development and validation of the QUECOMIICAT questionnaire: a tool to assess disease-related knowledge in patients with inflammatory bowel disease

“…However, we found that CD patients obtained significantly higher scores than UC patients, particularly in the clinic, treatment, surgery and lifestyle domains. A similar trend was observed in this study using the CCKNOW and in previous studies using the KQ and CCKNOW questionnaires (14,25,26). A reasonable explanation for this bias is that CD patients are more likely to need surgical resection to treat disease complications in the regular clinical practice and are more often hospitalized than UC patients (2).…”

Clinical Pharmacist’s Interventions on Medication Adherence and Knowledge of Inflammatory Bowel Disease Patients

“…27 Patients diagnosed at younger age, having higher education qualifications (college/post graduate) had high CCKNOW score. This is a similar result from the study conducted by Jason K Hou et al 28 Patients in the young age groups had higher CCKNOW score as they require more information, regarding effective management of disease, than the other ones since they are active participants in social activities. Rather than high school graduates, university graduates showed more interest in disease management.…”
