Applying a quality use of medicines framework to using essential oils in nursing practice

Nurses are increasingly incorporating complementary therapies into their practices. Aromatherapy is one of the most popular therapies. The basis of aromatherapy is essential oils, which are chemically active substances with a long history of safe traditional use and a growing evidence base to support their use in nursing care. In Australia, essential oils are classified and regulated under the same policies as conventional medicines such as the National Medicines Policy and the Quality Use of Medicines (QUM) framework applies. QUM is a framework for selecting and using medicines safely and effectively if medicines are indicated. The key elements of QUM are a systems-based approach to using medicines based on relevant evidence, partnerships, and informed client consent. Clients are placed at the centre of a QUM medication management process, which is consistent with holistic care. Applying a QUM approach to essential oil use, Quality Use of Essential Oils (QUEO), involves developing effective systems for managing essential oils from an holistic perspective that includes structured assessment and diagnostic processes to enable effective essential oil prescribing and outcome monitoring. In a QUEO approach, essential oils are integrated into the client's overall medication regimen and care plan rather than being used as ‘add-ons’. Adopting QUEO is consistent with the current national focus on the quality use of therapeutic substances, increases the profile of aromatherapy in nursing care and provides important information to guide future aromatherapy practices.

The development of a medication calculation competency and quality use of renal medicine e-learning program.

Medication calculation and administration are commonly performed nursing tasks. A consequence of this frequency is thepotential for a higher incidence of medication-related errors. One strategy to assess proficiency in medication calculation is an annual medication calculation competency quiz. Traditionally, these quizzes are done in paper form at an institutional level and require educators or managers to administer and mark the quiz manually by hand. This paper discusses the rationale, challenges and peer-review process associated with the development of an e-learning programme designed to assess proficiency in medication calculation and the quality use of renal medicines.

What are the perceived learning needs of Australian general practice registrars for quality prescribing?

BACKGROUND: Little is known about the perceived learning needs of Australian general practice (GP) registrars in relation to the quality use of medicines (QUM) or the difficulties experienced when learning to prescribe. This study aimed to address this gap. METHODS: GP registrars' perceived learning needs were investigated through an online national survey, interviews and focus groups. Medical educators' perceptions were canvassed in semi-structured interviews in order to gain a broader perspective of the registrars' needs. Qualitative data analysis was informed by a systematic framework method involving a number of stages. Survey data were analysed descriptively. RESULTS: The two most commonly attended QUM educational activities took place in the workplace and through regional training providers. Outside of these structured educational activities, registrars learned to prescribe mainly through social and situated means. Difficulties encountered by GP registrars included the transition from hospital prescribing to prescribing in the GP context, judging how well they were prescribing and identifying appropriate and efficient sources of information at the point of care. CONCLUSIONS: GP registrars learn to prescribe primarily and opportunistically in the workplace. Despite many resources being expended on the provision of guidelines, decision-support systems and training, GP registrars expressed difficulties related to QUM. Ways of easing the transition into GP and of managing the information 'overload' related to medicines (and prescribing) in an evidence-guided, efficient and timely manner are needed. GP registrars should be provided with explicit feedback about the process and outcomes of prescribing decisions, including the use of audits, in order to improve their ability to judge their own prescribing.

Do high-risk medicines alerts influence practice?

Background: Medicine-related adverse events are prevalent, costly and mostly preventable. The High Risk Medicines Working Party (Victoria) developed and distributed three highrisk medicines alerts – wrong route of administration of oral medicines, subcutaneous insulin and unfractionated heparin – and accompanying audit tools in 2008 and 2009.
Aims: To determine the impact of the three high-risk medicines alerts on Victorian health services; to assess the clinical relevance and utility of the audit tools; to identify barriers to implementing recommendations; and to obtain feedback and suggestions for future alert topics.
Method: A cross-sectional survey was undertaken from 6 to 31 July 2009 using an online questionnaire. The questionnaire was distributed to 90 metropolitan, regional and rural public health services in Victoria and approximately 200 members of the Quality Use of Medicines Network (Victoria).
Results: Most of the 90 respondents were pharmacists (53%) and nurses (31%). 53 (59%) respondents reported making changes as a result of receiving the high-risk medicines alerts – 21 (40%) concerned the wrong route of administration, 12 (23%) subcutaneous insulin and 7 (13%) unfractionated heparin. Barriers to implementation included time constraints, inadequate staff and resources, excessive paperwork and competing priorities. A minority of respondents indicated some alerts were not relevant to small rural services. Suggestions for
improving the audit tools included making them less labour intensive, enabling electronic responses and ensuring their distribution is coordinated with other medicine-related tools.
Conclusion: High-risk medicines alerts and the accompanying audit tools facilitated change but there were some barriers to their implementation, such as time and resource constraints. Not all alerts and audit tools were relevant to all health services.

Clincial pharmacogenetics and potential application in personalized medicine

The current `fixed-dosage strategy' approach to medicine, means there is much inter-individual variation in drug response. Pharmacogenetics is the study of how inter-individual variations in the DNA sequence of specific genes affect drug responses. This article will highlight current  pharmacogenetic knowledge on important drug metabolizing enzymes, drug transporters and drug targets to understand interindividual variability in drug clearance and responses in clinical practice and potential use in  personalized medicine. Polymorphisms in the cytochrome P450 (CYP) family may have had the most impact on the fate of pharmaceutical drugs. CYP2D6, CYP2C19 and CYP2C9 gene polymorphisms and gene duplications account for the most frequent variations in phase I metabolism of drugs since nearly 80% of drugs in use today are metabolised by these enzymes. Approximately 5% of Europeans and 1% of Asians lack CYP2D6 activity, and these  individuals are known as poor metabolizers. CYP2C9 is another clinically significant drug metabolising enzyme that demonstrates genetic variants. Studies into CYP2C9 polymorphism have highlighted the importance of the CYP2C9*2 and CYP2C9*3 alleles. Extensive polymorphism also occurs in a majority of Phase II drug metabolizing enzymes. One of the most important polymorphisms is thiopurine S-methyl transferases (TPMT) that catalyzes the S-methylation of thiopurine drugs. With respect to drug transport  polymorphism, the most extensively studied drug transporter is  P-glycoprotein (P-gp/MDR1), but the current data on the clinical impact is limited. Polymorphisms in drug transporters may change drug's distribution, excretion and response. Recent advances in molecular research have revealed many of the genes that encode drug targets demonstrate genetic polymorphism. These variations, in many cases, have altered the targets sensitivity to the specific drug molecule and thus have a profound effect on drug efficacy and toxicity. For example, the β2-adrenoreceptor, which is encoded by the ADRB2 gene, illustrates a clinically significant genetic variation in drug targets. The variable number tandem repeat polymorphisms in serotonin transporter (SERT/SLC6A4) gene are associated with response to antidepressants. The distribution of the common variant alleles of genes that encode drug metabolizing enzymes, drug transporters and drug targets has been found to vary among different populations. The promise of pharmacogenetics lies in its potential to identify the right drug at the right dose for the right individual. Drugs with a narrow therapeutic index are thought to benefit more from pharmacogenetic studies. For example, warfarin serves as a good practical example of how pharmacogenetics can be utilized prior to commencement of therapy in order to achieve maximum efficacy and minimum toxicity. As such, pharmacogenetics has the potential to achieve optimal quality use of medicines, and to improve the efficacy and safety of both prospective and licensed drugs.

Small-scale rural pilot programs in chronic illness management - what next?

In recent years, rural SA has been the recipient of significant funding to support a range of new primary health care initiatives. Much of this funding, additional to normal recurrent budgets in our health system, has facilitated effective change and development through demonstration and research projects across the state. The resultant work involves programs such as: ? coordinated care trials (COAG) ? more allied health services (MAHS) ? Commonwealth regional health service initiatives (CRHS) ? quality use of medicines (QUM) ? community packages for aged care services ? Indigenous chronic disease self-management pilot programs (CDSM) ? chronic disease self-management (CDSM) programs - Sharing Health Care SA ? chronic disease self-management (CDSM) programs in Indigenous communities. In addition to the resources listed above, funding was also provided by the Commonwealth to establish the South Australian Centre for Rural and Remote Health (SACRRH) and develop the University Department of Rural Health in Whyalla. While this new funding has led to substantial developmental work in chronic illness management in particular, one needs to ask whether the time might not be right now for these hitherto small-scale change initiatives to be transformed into ongoing mainstream programs, informed and guided by research outcomes to date. Is it time to move beyond tentative chronic illness programs and into mainstream reform? We have shown that there is much to be gained, both for patients and for the system, from improved coordination of primary care services and initiatives such as self-management programs for patients with chronic conditions. Better management leads to improved patient health outcomes and can reduce demand for unplanned hospital and emergency services. Many admissions to rural hospitals requiring expensive services, in terms of infrastructure and staffing, could be either prevented, or patients could be managed more effectively in the community as part of a wider primary health care program.

Estimating quality costs in an automotive stamping plant through the use of simulation

The pressures of modern manufacturing require that the quality-cost benefits are determined when evaluating new procedures or alternative operating policies. Traditionally, cost reports and other quality metrics have been used for this purpose. However, the interactions between the main quality cost drivers cannot be understood at the superficial level and the effect that a new process or an alternative operating policy may have on quality costs is difficult to determine. An alternative to the traditional costing methods is simulation. The current work uses simulation to evaluate quality costs in an automotive stamping plant where the quality control is determined by operator inspection of their own work. Self-inspection quality control provides instantaneous feedback of quality problems, allowing for quick rectification. However, the difficult nature of surface finish inspection of automotive panels can create inspection and control errors. A simulation model was developed to investigate the cost effects of inspection and control errors and it was found that inspection error had a significant effect in increasing total quality cost, with the magnitude of this increase dependent on the level of control. Further, the simulation found that the lowest cost quality control policy was that which allowed a number of defective panels to accumulate before resetting the press-line.

Use of complementary and alternative medicines by a sample of Australian women during pregnancy

Background: The use of complementary and alternative medicines (CAM) is growing in Australia, with women higher users than men. Yet, only a few Australian studies have explored the use of CAM during pregnancy.

Aims: To explore the use of CAM, the types of CAM practitioners consulted, physical symptoms/complaints for which CAM are used by a sample of pregnant Australian women, and women's perceptions of the efficacy of CAM in treating those complaints.

Methods: Three hundred and twenty-one pregnant women, who volunteered for a study exploring women's well-being during pregnancy, completed a self-report questionnaire in their late second/early third trimester.

Results: Seventy-three per cent of women had used at least one kind of complementary therapy in the prior eight weeks of pregnancy. Over one-third of the women had visited at least one alternative medicine practitioner during pregnancy. Approximately one-third of the women reported taking CAM to alleviate a specific physical symptom, with 95.7% of these women reporting they either got completely better or a little bit better with use of CAM; one quarter reported planning to use an alternative therapy to assist with labour preparation. Age, number of physical symptoms experienced, income level and level of education were not associated with greater use of CAM (P < 0.05); however, women reporting more physical symptoms were more likely to consult a CAM practitioner.

Conclusion: Findings highlight the substantial use of CAM during pregnancy and the need to have all health professionals adequately informed about such therapies during this life stage.

Principals' perceptions of the use of total quality management concepts for school improvement in Mauritius : leading or misleading?

As a small island country, Mauritius is relying on its human capital and innovative hi-tech industry to ensure future economic viability in the global market. As such, Mauritian education authorities are seeking ways to raise educational standards. One idea being canvassed is that Total Quality Management (TQM) could provide the framework for Mauritian school leaders to deliver imperatives for change and improvement and to achieve the aim of ‘world- class quality education.’ This paper reports the findings of a research into Mauritian principals’ current practices in line with TQM tenets and their perceptions about the usefulness or otherwise of ideas implicit in TQM. The findings indicate that whilst principals agree with current progressive notions and thinking compatible with the TQM philosophy, they have not fully translated them into their practice. The paper identifies challenges and opportunities worthy of discussion for school improvement in twenty-first century Mauritius with its high-tech, world-class ambitions.
