A longitudinal analysis of self-prescribed complementary and alternative medicine use by a nationally representative sample of 19,783 Australian women, 2006-2010

BACKGROUND: Complementary and alternative medicine (CAM) use is increasingly popular amongst general populations around the world with women constituting substantial CAM users. However, self-prescribed CAM use does raise potential safety concerns and so it is important to identify those risk factors associated with self-prescribed CAM use. METHODS: Data was obtained from the Australian Longitudinal Study on Women's Health (ALSWH). Longitudinal data analyses were conducted on questionnaire data from the 1973-78 cohort (n=9,145) and the 1946-51 cohort (n=10,638), collected over the period 2006-2010. RESULTS: In the 1973-78 cohort, use of self-prescribed CAM was 73.2% in 2006 and 75.3% in 2009. For the 1946-51 cohort, use of self-prescribed CAM was 73.9% in 2007 and 74.7% in 2010. There were similar levels of use of individual self-prescribed CAM, with the exception that the use of herbal medicine was much higher among the 1946-51 cohort (20% vs. 27%). There was a substantial increase over three years in the use of vitamins/minerals in both cohorts (21% and 19%, respectively). In contrast, there was a considerable decline over three years in use of aromatherapy oils in both cohorts (34% and 28%, respectively). CONCLUSION: Self-prescribed CAM use is popular amongst women in Australia and it is important that conventional practitioners providing women's health care be cognizant of such use amongst their patients. In order to ensure effective practice, there is a need for further research to explore women's decision-making and experiences around self-prescribed CAM use.

Understanding quality of life in medicine : a new approach

This article introduces the subjective side of quality of life as it has evolved within the discipline of psychology. Subjective well-being is also of special interest within medicine due to its links to pathology and the fact that it is managed by a homeostatic system. This form of management offers an explanation for the unusual properties of subjective well-being, including its normal positivity, stability, and nonlinear relationship to objective variables, such as physical health. Central to understanding is the proposition that subjective well-being mainly consists of a specific form of trait mood. This homeostatically protected mood has a genetic set point and it is the experience of this set-point mood that homeostasis is defending. The resources required to maintain normal homeostatic control are described. If these resources are inadequate to protect the experience of set-point mood, mood positivity falls, and there is a high probability of depression. In this article, the process of homeostasis is shown to assist understanding of intervention effectiveness within both psychology and medicine. This concerns matters of resilience, the nonlinear relationship between levels of subjective well-being, and the strength of challenging agents, and the important understanding that interventions designed to raise subjective well-being are critically dependent on its level at baseline. Key teaching points: • The physiological process of homeostasis has a parallel in psychology in the homeostatic management of subjective well-being. • Subjective well-being is a more globally informative construct than health-related quality of life. • How people feel about themselves and their lives cannot be simply predicted through measures of health. • When subjective well-being homeostasis is defeated, there is a high probability of depression.

"Cancer 2015": a prospective, population-based cancer cohort-phase 1: feasibility of genomics-guided precision medicine in the clinic

"Cancer 2015" is a longitudinal and prospective cohort. It is a phased study whose aim was to pilot recruiting 1000 patients during phase 1 to establish the feasibility of providing a population-based genomics cohort. Newly diagnosed adult patients with solid cancers, with residual tumour material for molecular genomics testing, were recruited into the cohort for the collection of a dataset containing clinical, molecular pathology, health resource use and outcomes data. 1685 patients have been recruited over almost 3 years from five hospitals. Thirty-two percent are aged between 61-70 years old, with a median age of 63 years. Diagnostic tumour samples were obtained for 90% of these patients for multiple parallel sequencing. Patients identified with somatic mutations of potentially "actionable" variants represented almost 10% of those tumours sequenced, while 42% of the cohort had no mutations identified. These genomic data were annotated with information such as cancer site, stage, morphology, treatment and patient outcomes and health resource use and cost. This cohort has delivered its main objective of establishing an upscalable genomics cohort within a clinical setting and in phase 2 aims to develop a protocol for how genomics testing can be used in real-time clinical decision-making, providing evidence on the value of precision medicine to clinical practice.

Complementary medicine use among people living with HIV/AIDS in Victoria, Australia: practices, attitudes and perceptions

There is limited evidence suggesting the underlying reasons for the use of complementary and alternative medicines (CAMs) by people with HIV/AIDS, or individual attitudes and beliefs about the use of CAMs. Using focus groups and a survey with 151 individuals attending the HIV Clinics at The Alfred Hospital, Melbourne, we aimed to provide insights into factors that influence the use of CAMs among people living with HIV/AIDS. Roughly half (49%) of the participants had used CAMs to manage their HIV/AIDs. Users of CAMs utilized a wide range of treatments in managing their condition, but costs of the CAMs meant that users were not necessarily able to use them as much as they might have liked. Use of CAMs was based on a desire to find something beneficial rather than on being dissatisfied with conventional medicine. Further research is needed into (a) the effects of CAMs and (b) the enhancement of communication and collaboration between patients, doctors and complementary medicine practitioners.

The construction of power in family medicine bedside teaching: a video observation study

INTRODUCTION: Bedside teaching is essential for helping students develop skills, reasoning and professionalism, and involves the learning triad of student, patient and clinical teacher. Although current rhetoric espouses the sharing of power, the medical workplace is imbued with power asymmetries. Power is context-specific and although previous research has explored some elements of the enactment and resistance of power within bedside teaching, this exploration has been conducted within hospital rather than general practice settings. Furthermore, previous research has employed audio-recorded rather than video-recorded observation and has therefore focused on language and para-language at the expense of non-verbal communication and human-material interaction. METHODS: A qualitative design was adopted employing video- and audio-recorded observations of seven bedside teaching encounters (BTEs), followed by short individual interviews with students, patients and clinical teachers. Thematic and discourse analyses of BTEs were conducted. RESULTS: Power is constructed by students, patients and clinical teachers throughout different BTE activities through the use of linguistic, para-linguistic and non-verbal communication. In terms of language, participants construct power through the use of questions, orders, advice, pronouns and medical/health belief talk. With reference to para-language, participants construct power through the use of interruption and laughter. In terms of non-verbal communication, participants construct power through physical positioning and the possession or control of medical materials such as the stethoscope. CONCLUSIONS: Using this paper as a trigger for discussion, we encourage students and clinical teachers to reflect critically on how their verbal and non-verbal communication constructs power in bedside teaching. Students and clinical teachers need to develop their awareness of what power is, how it can be constructed and shared, and what it means for the student-patient-doctor relationship within bedside teaching.
