Complementary medicine (CM) is used by one third to one half of cancer patients throughout the world. The objective of this study was to describe the prevalence of CM use and the potential for interactions with cancer treatments in an academic oncology centre. A cross-sectional study was conducted among patients undergoing current cancer treatment. Among 132 included patients, 56% had used CM since their cancer diagnosis and 45% were using CM during cancer treatment at the time of the survey. The main CM used were green tea (35%), herbal tea (35%), homeopathy (27%), dietary supplements (27%), and herbal medicines (27%). A small majority of patients (58%) spontaneously mentioned the use of CM to their oncologist. Of 42 identified combinations of concomitant use of biologically based CM and anticancer agents among the study patients, the potential for pharmacokinetic interactions of clinical relevance was not expected in 17 combinations (40%), hypothetical and deemed unlikely in 23 (55%), and of probable low clinical relevance in 2 (5%). Considering the high prevalence of CM use, active enquiries should be made by healthcare professionals to detect symptoms that may relate to CM tolerance and effects or that suggest interactions between CM and cancer treatments.
Medically unexplained symptoms (MUS) are common among adolescents and an important cause of clinical visits. This study sought to understand the experiences with, and perceptions of, the healthcare of adolescents who have MUS and their parents. Using a qualitative approach, six focus groups and two individual interviews were conducted with a total of ten adolescents and sixteen parents. The participants were recruited in a university hospital in Switzerland. A thematic analysis was conducted in accordance with the Grounded Theory. Six main themes emerged: needing a label for the symptoms, seeking an etiology to explain the symptoms, negotiating the medical system, medication and treatments, interactions with doctors, and the inclusion of parents during consultations. Transcending these themes, however, was the need for good communication between the adolescents, their parents and the clinicians. When explaining the symptoms, clinicians should make sure to discuss the results, investigations and lack of organic origin.
BackgroundComplementary medicine (CM) is utilized in a growing number of academic centers despite the debate concerning its value, risks and benefits. Healthcare professionals often feel uncomfortable discussing CM with patients, and little is known about their sources of knowledge in the field of CM.ObjectiveTo assess healthcare professionals’ sources of knowledge and attitude toward CM in an academic hospital.Design and participantsThe cross-sectional web-based survey took place from October to December 2013. A total of 4,925 healthcare professionals working at Lausanne University Hospital, Switzerland, were invited to answer the questionnaire.Main measuresFactors influencing healthcare professionals’ opinion toward CM, knowledge and communication about CM.Key resultsThe questionnaire was answered by 1,247 healthcare professionals. The three key factors influencing professionals’ opinion toward CM were personal experience, clinical experience and evidence demonstrating the physiological mechanism of CM. Personal experience was more associated with nurses’ and midwives’ opinion compared to physicians’ (80.8% vs 57.1%, OR = 3.08, [95% CI: 2.35–4.05], P<0.001 and 85.3% vs 57.1%, OR = 3.83, [95% CI: 1.95–7.53], P<0.001, respectively) as well as with professionals trained in CM compared to non-trained professionals (86.0% vs 73.2%, OR = 2.60, [95% CI: 1.92–3.53], P<0.001). Physicians relied more on randomized controlled clinical trials compared to nurses (81.3% vs 62.9%, OR = 0.43, [95% CI: 0.33–0.57], P<0.001). A majority of the respondents (82.5%) agreed that they lacked knowledge about CM and 65.0% noted that it was the patient who initially started the discussion about CM.ConclusionsDifferent professionals used different strategies to forge opinions regarding CM: physicians relied more on scientific evidence, while nurses and midwives were more influenced by personal experience. Regardless of preferred information source, most respondents did not feel prepared to address patient questions regarding CM. Enhancing interprofessional education opportunities is an important strategy to help providers become empowered to discuss CM with patients. This in turn will help patients making informed decisions in their healthcare.
