An evidence-based approach to podiatry workforce enhancement and service provision in Western Victoria

Aims & rationale/Objectives : The objectives of this workforce and service enhancement project include: (i) establishing the magnitude of podiatry needs; and (ii) developing a model that can be used to enhance podiatry workforce and podiatry services.
Methods : Surveys to podiatrists and health agencies to determine vacancies, waiting lists, work practices and recruitment methods. Desktop analysis of predictive data for burden of disease and population changes per local government area (LGA). Meetings with podiatrists and their professional association, health care agencies, universities, and Local and State Governments.
Principal findings : Results showed
Long podiatry waiting lists (up to 12 months)
Podiatry vacancies and service gaps
Absence of qualified foot assistants
A high chronic disease burden
A population age mix that is predicted to change dramatically over the next 25 years in favour of those who are 60 years of age or older
Ineffective recruitment methods
The workforce enhancement model that emanated from the meetings with the steering group includes podiatrists as well as auxiliaries such as foot-care assistants who work together in an interprofessional model of care that expands across the region. In addition to training foot-care assistants and the development of a podiatry teaching clinic to enhance student placement, the model builds onto a current continuous professional development program for allied health professionals.
Discussion : Although the allied health workforce (including podiatry) is playing an increasingly important role in the prevention and treatment of chronic diseases, rural areas in particular are disadvantaged by recruitment and retention problems. The podiatry workforce shortage is compounded by ageing populations. Age is associated with increased podiatry usage due to chronic diseases such as diabetes, cardiovascular disease and osteoarthritis.
Implications : A strategic plan developed in consultation with stakeholders aims to improve rural podiatry services in a sustainable manner. The project will be implemented when adequate funding is allocated this year and will be evaluated on its impact on services.

Evidence based drug therapy : are optimal doses and multiple medication therapies realistic in patients with chronic heart failure

Background: Chronic Heart Failure (CHF) has a high mortality and morbidity. Large scale randomised controlled trials have proven the benefits of beta blockade and ACE inhibitors in reducing mortality in patients with CHF and expert guidelines mandate their use. In spite of these recommendations, important therapies are under-prescribed and under-utilised.

Method: 1015 consecutive patients enrolled in CHF management programs across Australia were surveyed during 2005-2006 to determine prescribing patterns in heart failure medications. These patients were followed-up for a period of 6 months.

Results: The survey revealed that beta blockers were prescribed to 80% of patients (more than 85% were on sub-optimal doses) and 70% were prescribed Angiotensin converting enzyme (ACE) inhibitors (approximately 50% were on sub-optimal dose). 19% of patients were prescribed Angiotensin receptor blockers (ARBs). By 6 months <25% of the patients who were on sub-optimal dose beta blockers or ACE inhibitors at baseline, had been up-titrated to maximum dose (p<0.0001). In CHF programs, were nurses were able to titrate medications, 75% of patients reached optimal dose of beta blockers compared to those programs with no nurse-led medication titration, where only 25% of patients reached optimal dose (p<0.004). When examining optimal dosage for any two of these mandatory medications, less patients were on optimal therapy. Beta blockers and ACE inhibitors, were both prescribed in combination in 60% of patients. While beta blockers and ARBs were prescribed to 15% of patients.

Conclusion: Whilst prescribing rates for a single medication strategy of beta blockers, or ACE inhibitors were greater than 70%, an increase in dosage of these medications and utilisation of proven combination therapy of these medications was poor. It is suggested that clinical outcomes for this cohort of patients could be further improved by adherence to evidence-based practice, ESC guidelines, and optimisation of these medications by heart failure nurses in a CHF program. On the basis of these findings and in the absence of ready access to a polypill, focussing on evidence-based practice to increase utilisation and optimal dosage of combination medication therapy is critical.

Implementation of evidence into practice : Development of a tool to improve emergency nursing care of acute stroke

Background
Stroke is an increasing global health issue that places considerable burden on society and health care services. An important part of acute stroke management and decreasing stroke-related mortality is preventing complications within the first 24–48 hours. The current climate of prolonged time spent in the Emergency Department (ED) means that many aspects of stroke management are now the responsibility of emergency nurses.

Aims
The aims of this paper are to: i) examine the evidence related to nursing care of acute stroke, ii) identify evidence-based elements of stroke care with most applicability to emergency nursing and iii) use evidence-based stroke care recommendations to develop a guideline for the emergency nursing management of acute stroke.

Results
Emergency nursing care of acute stroke should focus on optimal triage decisions, physiological surveillance, fluid management, risk management, and early referral to specialists.

Conclusions
The role of emergency nurses in stroke care will increase and it is important that emergency nurses deliver evidence-based stroke care in order to optimise patient outcomes. Guidelines and decision support tools for use in emergency nursing must be practical and have high levels of clinical utility for maximum uptake in a busy clinical environment.

Does an evidence-based sedation protocol improve practice and patient outcomes in critical care?

Learning Objective 1: compare protocol-directed sedation management with traditional non-protocol-directed practice in mechanically ventilated patients in an Australian critical care.

Learning Objective 2: explain the contrasting international research findings on sedation protocol implementation.
Minimization of sedation in critical care patients has recently received widespread support. Professional organizations internationally have published sedation management guidelines for critically ill patients to improve the use of research in practice, decrease practice variability and shorten mechanical ventilation duration. Innovations in practice have included the introduction of decision making protocols, daily sedation interruptions and new drugs and monitoring technologies. The aim of this study was to compare protocol-directed sedation management with traditional non-protocol-directed practice in mechanically ventilated patients in an Australian critical care setting.

A randomized, controlled trial design was used to study 312 mechanically ventilated adult patients in a general critical care unit at an Australian metropolitan teaching hospital. Patients were randomly assigned to receive protocol directed sedation management developed from evidence based guidelines (n=153) or usual clinical practice (n=159).

The median (95% CI) duration of ventilation was 58 hrs (44–78 hrs) for patients in the non-protocol group and 79 hrs (56–93) for those patients in the protocol group (p=0.20). Results were not significant for length of stay in critical care or hospital, the frequency of tracheostomies, and unplanned extubations. A Cox proportional hazards model estimated that protocol directed sedation management was associated with a 22% decrease (95% CI: 40% decrease to 2% increase, p=0.07) in the occurrence of successful weaning from mechanical ventilation.

Few randomized controlled trials have evaluated the effectiveness of protocol-directed sedation outside of North America. This study highlights the lack of transferability between different settings and different models of care. Qualified, high intensity nursing in the Australian critical care setting facilitates rapid, responsive decisions for sedation management and an increased success rate for weaning from mechanical ventilation.
