The challenge of pharmaceutical promotion regulation in Malaysia.
Information on medicines provided to doctors should be of high quality to support the quality use of medicines. Pharmaceutical promotion is used by pharmaceutical companies to disseminate information about their medicines to doctors. Although the companies claim that promotion offers evidence-based information, research shows that pharmaceutical promotion often provide bias and poor quality of information that may negatively influence doctors' prescribing behaviour. In Malaysia, the pharmaceutical market is highly competitive. It appears
that pharmaceutical companies actively promoting their medicines to Malaysian doctors. Given the absence of a comprehensive independent source of prescribing information in Malaysia, Malaysian doctors may be more likely to rely on medicines information provided by pharmaceutical companies. Clearly, pharmaceutical promotional activities in Malaysia need to be effectively regulated. This article will discuss the regulation of pharmaceutical promotion and
current policy challenges in Malaysia
Quality and availability of consumer information on heart failure in Australia
<p>Abstract</p> <p>Background</p> <p>Provision of consumer information and patient education are considered an essential part of chronic disease management programmes developed for patients with heart failure. This study aimed to review the quality and availability of consumer information materials for people with heart failure in Australia.</p> <p>Methods</p> <p>The availability of consumer information was assessed through a questionnaire-based survey of the major organisations in Australia known, or thought, to be producing or using consumer materials on heart failure, including hospitals. The questionnaire was designed to explore issues around the use, production and dissemination of consumer materials. Only groups that had produced consumer information on heart failure were asked to complete the totality of the questionnaire.</p> <p>The quality of information booklets was assessed by using a standardised checklist.</p> <p>Results</p> <p>Of 101 organisations which were sent a questionnaire, 33 had produced 61 consumer resources on heart failure including 21 information booklets, 3 videos, 5 reminder fridge magnets, 7 websites, 15 self-management diaries and 10 self-management plans. Questionnaires were completed for 40 separate information resources. Most had been produced by hospitals or health services. Two information booklets had been translated into other languages. There were major gaps in the availability of these resources as more than half of the resources were developed in 2 of the 8 Australian states and territories, New South Wales and Victoria.</p> <p>Quality assessment of 19 information booklets showed that most had good presentation and language. Overall eight high quality booklets were identified. There were gaps in terms of topics covered, provision of references, quantitative information about treatment outcomes and quality and level of scientific evidence to support medical recommendations. In only one case was there evidence that consumers had been involved in the production of the booklets.</p> <p>Conclusion</p> <p>Key findings arising from the study included the need to develop a nationally coordinated approach for increasing the dissemination of information resources on heart failure. While the more recent publication of a booklet by the National Heart Foundation may have improved the situation, dissemination of written information materials may remain sub-optimal, especially among patients who are not enrolled in chronic heart failure management programmes.</p
Pharmaceutical promotion : the theoretical framework of regulation.
Pharmaceutical promotion IS persuaSIve communication (World Health Organization, 2010) which often creates the impression of superior efficacy of a medicine, \vithout a\vareness of the health professionals (Mansfield & Henry, 2004). Doctors often use pharmaceutical promotion as
a source of medicines information (Fischer et a1., 2009~ McKinney et aI., 1990~ National Survey ofPhysicians (2002), Poirier et aI., 1994; Prosser et a!., 2003 ~ Strang et aI., 1996; Uchenna et aI., 2010) and it may influence their prescribing pattern (Andersen et aI., 2006~ Muijrers et aI., 2005). For this reason, it is essential that the medicines information provided in pharmaceutical
promotion should be effectively regulate
Medicines information provided by pharmaceutical representatives: a comparative study in Australia and Malaysia
Background:
Pharmaceutical representatives provide medicines information on their promoted products to
doctors. However, studies have shown that the quality of this information is often low. No study has assessed the
medicines information provided by pharmaceutical representatives to doctors in Malaysia and no recent evidence in Australia is present. We aimed to compare the provision of medicines information by pharmaceutical
representatives to doctors in Australia and Malaysia.
Methods: Following a pharmaceutical representative’s visit, general practitioners in Australia and Malaysia who had
agreed to participate, were asked to fill out a questionnaire on the main product and claims discussed during the encounter. The questionnaire focused on provision of product information including indications, adverse effects,precautions, contraindications and the provision of information on the Pharmaceutical Benefit Scheme (PBS) listings and restrictions (in Australia only). Descriptive statistics were produced. Chi-square analysis and clustered linear regression were used to assess differences in Australia and Malaysia.
Results:
Significantly more approved product information sheets were provided in Malaysia (78%) than in Australia(53%) (P < 0.001). In both countries, general practitioners reported that indications (Australia, 90%, Malaysia, 93%) and
dosages (Australia, 76%, Malaysia, 82%) were frequently provided by pharmaceutical representatives. Contraindications, precautions, drug interactions and adverse effects were often omitted in the presentations (range 25% - 41%). General practitioners in Australia and Malaysia indicated that in more than 90% of presentations,
pharmaceutical representatives partly or fully answered their questions on contraindications, precautions, drug
interactions and adverse effects. More general practitioners in Malaysia (85%) than in Australia (60%) reported that pharmaceutical representatives should have mentioned contraindications, precautions for use, drug interaction or adverse effects spontaneously (P < 0.001). In 48% of the Australian presentations, general practitioners reported the pharmaceutical representatives failed to mention information on PBS listings to general practitioners.
Conclusions:
Information on indications and dosages were usually provided by pharmaceutical representatives in
Australia and Malaysia. However, risk and harmful effects of medicines were often missing in their presentations.
Effective control of medicines information provided by pharmaceutical representatives is needed
Influence of Comorbidities on Therapeutic Progression of Diabetes Treatment in Australian Veterans: A Cohort Study
BACKGROUND: This study assessed whether the number of comorbid conditions unrelated to diabetes was associated with a delay in therapeutic progression of diabetes treatment in Australian veterans. METHODOLOGY/PRINCIPAL FINDINGS: A retrospective cohort study was undertaken using data from the Australian Department of Veterans' Affairs (DVA) claims database between July 2000 and June 2008. The study included new users of metformin or sulfonylurea medicines. The outcome was the time to addition or switch to another antidiabetic treatment. The total number of comorbid conditions unrelated to diabetes was identified using the pharmaceutical-based comorbidity index, Rx-Risk-V. Competing risk regression analyses were conducted, with adjustments for a number of covariates that included age, gender, residential status, use of endocrinology service, number of hospitalisation episodes and adherence to diabetes medicines. Overall, 20134 veterans were included in the study. At one year, 23.5% of patients with diabetes had a second medicine added or had switched to another medicine, with 41.4% progressing by 4 years. The number of unrelated comorbidities was significantly associated with the time to addition of an antidiabetic medicine or switch to insulin (subhazard ratio [SHR] 0.87 [95% CI 0.84–0.91], P<0.001). Depression, cancer, chronic obstructive pulmonary disease, dementia, and Parkinson's disease were individually associated with a decreased likelihood of therapeutic progression. Age, residential status, number of hospitalisations and adherence to anti-diabetic medicines delayed therapeutic progression. CONCLUSIONS / SIGNIFICANCE: Increasing numbers of unrelated conditions decreased the likelihood of therapeutic progression in veterans with diabetes. These results have implications for the development of quality measures, clinical guidelines and the construction of models of care for management of diabetes in elderly people with comorbidities.Agnes I.

Self-medication with over-the-counter drugs and complementary medications in South Australia's elderly population
A number of surveys have examined use of complementary and alternative
medicines (CAM) in Australia. However, there are limited Australian data on use of CAM and over-the-counter (OTC) medicines in the elderly population. The main aims of this study were to
examine self-medication practices with CAM and OTC medicines among older Australians and
variables associated with their use. Participants seemed to self-medicate in accordance with approved indications,
suggesting they were informed consumers, actively looking after their own health. However, use
of analgesics and aspirin are associated with an increased risk of adverse drug events in the elderly.
Future work should examine how self-medication contributes to polypharmacy and increases the
risk of adverse drug reactions
Prevalence of comorbidity of chronic diseases in Australia
<p>Abstract</p> <p>Background</p> <p>The prevalence of comorbidity is high, with 80% of the elderly population having three or more chronic conditions. Comorbidity is associated with a decline in many health outcomes and increases in mortality and use of health care resources. The aim of this study was to identify, review and summarise studies reporting the prevalence of comorbidity of chronic diseases in Australia.</p> <p>Methods</p> <p>A systematic review of Australian studies (1996 – May 2007) was conducted. The review focused specifically on the chronic diseases included as national health priorities; arthritis, asthma, cancer, cardiovascular disease (CVD), diabetes mellitus and mental health problems.</p> <p>Results</p> <p>A total of twenty five studies met our inclusion criteria. Over half of the elderly patients with arthritis also had hypertension, 20% had CVD, 14% diabetes and 12% mental health problem. Over 60% of patients with asthma reported arthritis as a comorbidity, 20% also had CVD and 16% diabetes. Of those with CVD, 60% also had arthritis, 20% diabetes and 10% had asthma or mental health problems.</p> <p>Conclusion</p> <p>There are comparatively few Australian studies that focused on comorbidity associated with chronic disease. However, they do show high prevalence of comorbidity across national health priority areas. This suggests integration and co-ordination of the national health priority areas is critical. A greater awareness of the importance of managing a patients' overall health status within the context of comorbidity is needed together with, increased research on comorbidity to provide an appropriate scientific basis on which to build evidence based care guidelines for these multimorbid patients.</p
The imperative of happiness for women living with breast cancer
Public and private discourses shape the manner in which women experience breast cancer, including their strategies for coping with negative feelings and making sense of illness. The dominant biomedical discourse views depressive feelings as a serious disease that needs to be medically treated. In contrast, the "existential" discourse acknowledges negative feelings as a "normal" and even needed process in the cancer journey and personal development. The medicalisation of suffering and the promotion of positive thinking as the moral normality may disempower women and impair the planning of coherent interventions that would take into account the broad social, cultural and community context.
Quality of claims, references and the presentation of risk results in medical journal advertising: a comparative study in Australia, Malaysia and the United States
Background
Journal advertising is used by pharmaceutical companies to disseminate medicine information to doctors. The quality of claims, references and the presentation of risk results in Australia and the US has been questioned in several studies. No recent evidence is available on the quality of claims, references and the presentation of risk results in journal advertising in Australia and the US and no Malaysian data have been published. The aim of this study was to compare the quality of claims, references and the presentation of risk results in journal advertising in these three countries.
Methods
A consecutive sample of 85 unique advertisements from each country was selected from journal advertising published between January 2004 to December 2006. Claims, references and the presentation of risk results in medical journal advertising were compared between the three countries.
Results
Less than one-third of the claims were unambiguous claims (Australia, 30%, Malaysia 17%, US, 23%). In Malaysia significantly less unambiguous claims were provided than in Australia and the US (P < 0.001). However, the unambiguous claims were supported by more references than other claims (80%). Most evidence was obtained from at least one randomized controlled trial, a systematic review or meta-analysis (Australia, 84%, Malaysia, 81%, US, 76%) with journal articles being the most commonly cited references in all countries. Data on file were significantly more likely to be cited in the US (17%) than in Australia (2%) and Malaysia (4%) (P < 0.001). Advertisements that provided quantitative information reported risk results exclusively as a relative risk reduction.
Conclusions
The majority of claims were vague suggesting poor quality of claims in journal advertising in these three countries. Evidence from a randomized controlled trial, systematic review or meta- analysis was commonly cited to support claims. However, the more frequent use of data that have not been published and independently reviewed in the US compared to Australia and Malaysia raises questions on the quality of references in the US. The use of relative rather than absolute benefits may overemphasize the benefit of medicines which may leave doctors susceptible to misinterpreting information
