Potential drug-drug interactions in patients with indication for prophylactic implantation of a cardioverter defibrillator: a cross-sectional analysis.

BACKGROUND: Due to demographic transition, multimorbidity and high numbers of medicinal products, polypharmacy rates will presumably further increase. This could lead to higher risks of potentially inappropriate medications with potential drug-drug interactions (PDDI). PDDI has already been investigated by several studies, but not for patients with indication for prophylactic implantation of a cardioverter defibrillator (ICD). Thus, the objective of this analysis was to examine the frequency of PDDI in that specific group of patients and compare patients with or without PDDI regarding potential underlying factors. METHODS: Cross-sectional data analyses were performed using data of the prospective EU-CERT-ICD study that primarily aimed to assess ICD effectiveness in Europe. Self-reported baseline medication data of patients from Germany and Switzerland were used. Patients who reported to take at least two drugs simultaneously for at least 80 days were defined as population at risk. By means of a publicly available interaction checker, we analyzed the medication data regarding occurrence and characteristics of PDDI categorized as minor, moderate, and major PDDI. The analyses were done using descriptive methods and chi square testing. RESULTS: The total population (n = 524) and the population at risk (n = 383) were rather similar with an average age of 64 years and about 80% male. PDDIs were found for 296 patients (in 57% of total population vs. 77% of population at risk). The moderate PDDI category was most frequently with 268 affected patients. Comparing patients with and without any PDDI, the proportion of patients with place of residence in Germany varied distinctly (93% vs. 78%). The frequency of any PDDI for the total population was twice as high in Germany as in Switzerland (p value < 0.001). CONCLUSIONS: PDDIs were frequently observed in this selected patient population and differed markedly between German and Swiss patients. The results should lead to higher awareness of polypharmacy and PDDIs. Adequate cooperation between health care providers should be promoted and new technologies such as drug interaction information systems or digital patient files used. TRIAL REGISTRATION: The EU-CERT-ICD study is registered at www.clinicaltrials.gov (NCT02064192).

Influence of Gender and Age on the Willingness to Reduce Nicotine Consumption-Results of a Survey in Urological Cancer Patients (KRAUT Study).

PURPOSE: Our objective was to investigate whether patients with urologic tumors were aware of smoking as a risk factor for the development and progression of several urologic cancers and the extent of the medical education they had received. Another aim was to investigate whether gender or age influenced patients' willingness to change their smoking habits. MATERIALS AND METHODS: Patients with histologically malignant urologic tumors were enrolled in our questionnaire-based study from September 2013 to December 2014 in 2 urology departments. Patients were asked about their smoking habits and their general understanding of the relationship between smoking and the onset of cancer (urologic cancer and lung cancer). Also, the extent of information they had acquired from a physician was assessed. The descriptive and oncologic data of the patients were recorded. RESULTS: Of 258 enrolled patients, 186 (72.1%) had never had an informational discussion with a doctor about smoking and their urologic tumor disease. Of the 160 active and former smokers, only 45 (28.1%) were planning to stop or reduce smoking because of their tumor disease. The willingness to change smoking habits was greater for women, with a statistically significant difference (odds ratio, 5.59; P = .002). Younger patients aged <58 years were also more willing to reduce or stop smoking. CONCLUSION: In our study, most patients with urologic cancer were unaware of smoking as the most probable cause of tumor development. The patients had not received proper counseling from doctors on smoking and the risk it poses for tumor progression. Efforts to balance compliance among the genders and age groups through risk-adapted counseling should be undertaken.

What do patients with urothelial cancer know about the association of their tumor disease with smoking habits? Results of a German survey study.

Purpose: Smoking represents a primary risk factor for the development of urothelial carcinoma (UC) and a relevant factor impacting UC-specific prognosis. Data on the accordant knowledge of UC-patients in this regard and the significance of physicians in the education of UC-patients is limited. Materials and Methods: Eighty-eight UC-patients were enrolled in a 23-items-survey-study aimed to analyse patient knowledge and awareness of their tumor disease with smoking along with physician smoking cessation counselling. Results: The median age of the study patients was 69 years; 26.1% (n=23), 46.6% (n=41), and 27.3% (n=24), respectively, were non-smokers, previous, and active smokers. Exactly 50% of active smokers reported a previous communication with a physician about the association of smoking and their tumor disease; however, only 25.0% were aware of smoking as main risk factor for UC development. Merely 33% of the active smokers had been prompted directly by their physicians to quit smoking. About 42% of active smokers had received the information that maintaining smoking could result in a tumor-specific impairment of their prognosis. Closely 29% of active and about 5% of previous smokers (during the time-period of active smoking) had been offered support from physicians for smoking cessation. No association was found between smoking anamnesis (p=0.574) and pack-years (p=0.912), respectively, and tumor stage of UC. Conclusions: The results of this study suggest that the medical conversation of physicians with UC-patients about the adverse significance of smoking is limited. Implementation of structured educational programs for smoking cessation may be an opportunity to further enhance comprehensive cancer care.

Effectiveness and Cost-Effectiveness of Tuina for Chronic Neck Pain: A Randomized Controlled Trial Comparing Tuina with a No-Intervention Waiting List.

OBJECTIVE: To evaluate whether tuina is more effective and cost-effective in reducing pain compared to no intervention in patients with chronic neck pain. DESIGN: Single-center randomized two-armed controlled trial. SETTING: University outpatient clinic specialized in Integrative Medicine. SUBJECTS: Outpatients with chronic neck pain were randomly allocated to tuina or no intervention. INTERVENTION: Six tuina treatments within 3 weeks. OUTCOME MEASURES: The primary outcome was the mean neck pain intensity during the previous 7 days on a visual analogue scale after 4 weeks (VAS, 0-100 mm, 0 = no pain, 100 = worst imaginable pain). Secondary outcomes included Neck Pain and Disability Scale (NPDS), Neck Disability Index (NDI), health-related quality of life (12-item quality-of-life questionnaire [SF-12]), medication intake, and cost-effectiveness after 4 and 12 weeks. Statistical analysis included analysis of covariance adjusted for baseline values and a full economic analysis from a societal perspective. RESULTS: Altogether, 92 outpatients were included (46 in both groups, 87% female, mean age 45.4 [standard deviation ±9.7], and mean VAS 57.7 ± 11.5). Tuina treatment led to a clinically meaningful reduction in neck pain intensity (group differences, 4 weeks: -22.8 mm [95% confidence interval, -31.7 to -13.8]; p < 0.001 and 12 weeks: -17.9 mm [-27.1 to -8.8], p < 0.001). No serious adverse events were observed. Total costs as well as quality-adjusted life years (QALYs) did not differ significantly between the groups. When taking group differences into account independently from their statistical significance, costs per QALY gained (incremental cost-effectiveness ratio) would range within a cost-effective area from €7,566 (for costs €10.28 per session) to €39,414 (cost €35 per session). CONCLUSION: An additional treatment with six tuina sessions over 3 weeks was effective, safe and relatively cost-effective for patients with chronic neck pain. A future trial should compare tuina to other best care options.
