Overwhelmed Patients A videographic analysis of how patients with type 2 diabetes and clinicians articulate and address treatment burden during clinical encounters

OBJECTIVE Patients with diabetes may experience high burden of treatment (BOT), including treatment-related effects and self-care demands. We examined whether patients with type 2 diabetes and their clinicians discuss BOT, the characteristics of their discussions, and their attempts to address BOT during visits. RESEARCH DESIGN AND METHODS Two coders independently reviewed videos of 46 primary care visits obtained during a practice-based trial and identified utterances concerning BOT, classifying them by topic and by whether BOT was addressed (i.e., whether statements emerged aimed at alleviating BOT). RESULTS Of the 46 visits, 43 (93.5%) contained BOT discussions. Both coders identified 83 discussions: 12 involving monitoring, 28 treatment administration, 19 access, and 24 treatment effects. BOT was unambiguously addressed only 30% of the time. CONCLUSIONS BOT discussions usually arise during visits but rarely beget problem-solving efforts. These discussions represent missed opportunities for reducing treatment-related disruptions in the lives of patients with diabetes, which may affect adherence and well-being.

Venous thromboembolism in patients with inflammatory bowel diseases: a case-control study of risk factors.

Background:Inflammatory bowel disease (IBD) is a well-known risk factor for venous thromboembolism (VTE). Existing guidelines for thromboprophylaxis in hospitalized patients do not extend to other clinical scenarios that may also be associated with VTE risk. Our aim was to estimate the fraction of VTE events in patients with IBD that could be prevented. Methods:A retrospective analysis assessed all patients with IBD diagnosed with VTE at a single academic medical center from 2002 to 2012. Confirmed cases were analyzed for VTE risk factors, inpatient status, the use of deep venous thrombosis prophylaxis, and when applicable the reason for omission of prophylaxis. IBD VTE cases were compared with age- and sex-matched non-IBD VTE controls with regards to risk factors and potential opportunities for VTE prevention. Results:There were 204 patients with IBD (108 ulcerative colitis, 96 Crohns disease) diagnosed with VTE (110 deep venous thrombosis, 66 pulmonary embolism, 27 intra-abdominal thromboses, and 1 other). One-third of the VTE events occurred in hospitalized patients. Two-third of the medical inpatients and 44% of surgical inpatients who developed VTE did not receive prophylaxis. Importantly, 129 VTE events occurred in outpatients. The proportion of outpatients hospitalized within 4 weeks of developing venous thrombosis was higher in patients with IBD than non-IBD controls (33% versus 15%, P = 0.0003). One-third (36%) of patients were experiencing ambulatory disease flares at the time of VTE diagnosis. Conclusions:A substantial portion of VTE events in patients with IBD occurred in clinical scenarios is not routinely recommended for thromboprophylaxis. Further investigation of primary prophylaxis for patients with IBD in high-risk outpatients may be warranted.

Why Do Women Reject Bisphosphonates for Osteoporosis? A Videographic Study

Background Despite access to effective, safe, and affordable treatment for osteoporosis, at-risk women may choose not to start bisphosphonate therapy. Understanding the reasons women give for rejecting a clinicians offer of treatment during consultations and how clinicians react to these reasons may help clinicians develop more effective strategies for fracture prevention and medication adherence. Methods We conducted a videographic evaluation of encounters in the Osteoporosis Choice randomized trial of a decision aid about bisphosphonates vs. usual primary care. Eligible videos involved consultations with women with an estimated 10-year fragility fracture risk >20% who verbalized at least one reason to not take bisphosphonates. Two reviewers independently reviewed eligible videos and verbatim transcripts, classifying patient views about bisphosphonate use, clinicians reponse to those views, and patient adherence at 6 months post visit. Results Eighteen video recordings (12 with decision aid) were eligible for analyses. We identified 37 reasons for and against bisphosphonate therapy. Eleven patients rejected treatment, offering 9 (average of 2 per patient) unique reasons against initiating bisphosphonates (most common: side effects 39% and distrust of medications in general 33%). When physicians conceded to patient views the outcome was no bisphosphonate use. Adherence to choices at 6 months was 100%. Conclusions The expression of patient preferences is sometimes unfavorable to bisphosphonates treatment even among well-informed patients at high risk for osteoporotic fractures. At 6 months, patients who expressed concerns about these medicines behaved consistently with the decision made during the visit.

Alterations in lipid, amino acid, and energy metabolism distinguish Crohn’s disease from ulcerative colitis and control subjects by serum metabolomic profiling

IntroductionBiomarkers are needed in inflammatory bowel disease (IBD) to help define disease activity and identify underlying pathogenic mechanisms. We hypothesized that serum metabolomics, which produces unique metabolite profiles, can aid in this search.ObjectivesThe aim of this study was to characterize serum metabolomic profiles in patients with IBD, and to assess for differences between patients with ulcerative colitis (UC), Crohn’s disease (CD), and non-IBD subjects.MethodsSerum samples from 20 UC, 20 CD, and 20 non-IBD control subjects were obtained along with patient characteristics, including medication use and clinical disease activity. Non-targeted metabolomic profiling was performed using ultra-high performance liquid chromatography/mass spectrometry (UPLC-MS/MS) optimized for basic or acidic species and hydrophilic interaction liquid chromatography (HILIC/UPLC-MS/MS).ResultsIn total, 671 metabolites were identified. Comparing IBD and control subjects revealed 173 significantly altered metabolites (27 increased and 146 decreased). The majority of the alterations occurred in lipid-, amino acid-, and energy-related metabolites. Comparing only CD and control subjects revealed 286 significantly altered metabolites (54 increased and 232 decreased), whereas comparing UC and control subjects revealed only five significantly altered metabolites (all decreased). Hierarchal clustering using significant metabolites separated CD from UC and control subjects.ConclusionsWe demonstrate that a number of lipid-, amino acid-, and tricarboxylic acid cycle-related metabolites were significantly altered in IBD patients, more specifically in CD. Therefore, alterations in lipid and amino acid metabolism and energy homeostasis may play a key role in the pathogenesis of CD.
