Critical care nurses' decision-making activities in the natural clinical setting

• This article reports on observation of 18 nurses in urban and rural based critical care settings.

• The purpose of the study was to observe and describe the decision-making activities of critical care nurses within natural clinical settings.

• During the 2-hour observation, the researcher dictated a detailed commentary on to audio-tape of each nurse's actions. Tapes were transcribed and subjected to content analysis.

• Findings indicated three main categories of decisions. Decision frequencies were linked to nurses' critical care experience, appointment level, and location, as well as nursing shifts.

• The findings are discussed in relation to previous empirical evidence and the implications for practice.

• The author concludes that future research should be directed towards measuring the contextual influences on nurses' decision-making on the outcome of patient care.

Examining communication and team performance during clinical handover in a complex environment : the private sector post-anaesthetic care unit

* Threats to patient safety during clinical handover have been identified as an ongoing problem in health care delivery.

* In complex handover situations, organisational, cultural, behavioural and environmental factors associated with team performance can affect patient safety by undermining the stability of team functioning and the effectiveness of interprofessional communication.

* We present a practical framework for promoting systematic, comprehensive measurement of the factors involved in clinical handover.

* The framework can be used to develop viable solutions to the problems of clinical handover.

* The framework was devised and used in a recent project examining interprofessional communication and team performance during clinical handover in post-anaesthetic care units.

* The framework combines five key concepts: clinical governance, clinician engagement, ecological validity, safety culture and team climate, and sustainability.

* We believe that use of this framework will help overcome the limitations of previous research that has not taken into account the complex and multifaceted influences on clinical handover and interprofessional communication.

The clinical utility of a suite of continence assessment tools for use in residential aged care facilities

According to the Institute of Medicine of the National Academies, 80% of direct care in nursing homes in the USA is provided by workforce that has least formal education about patient care (1). This situation is echoed in Australian residential aged care facilities where the day-to-day management is largely provided by unregulated workers (i.e. nursing assistants, personal carers and nursing aides) and is overseen by registered nurses. Some facilities additionally have access to expert advice from continence nurse advisors. In order to assist the residential aged care workforce to provide continence care that is evidence-based, a team of researchers developed and trialled a suite of continence assessment tools that were mainly targeted to unregulated workers. This paper presents information on the development of the tools (Stage 1) and on their evaluation (Stage 2).

MAAGs: the next generation. A study of the development of medical audit advisory groups and the arrangements for supporting clinical audit in primary care

Background: MAAGs have, historically, been disparate organisations with a lack of central direction, albeit with the same goal: to develop and support the performance of audit in primary care. This goal has been (and is being) achieved in a number of ways all over the country. In the last two years, MAAGs have witnessed many changes in primary care and are adapting themselves to suit these new arrangements at a local level.

Aim: To formalise our knowledge of where MAAGs are going, how they are getting there and the support they are receiving.

Method: A postal questionnaire to the 104 MAAGs in England and Wales, addressing 6 main issues of relevance to the development of MAAGs and the support they are receiving.

Results: At least two MAAGs have dissolved, leaving a possible total of 102 still in existence. Of these, 76 (74.5%) responded to the survey. The composition of the MAAG committee has changed dramatically since the inception of MAAGs in 1990, and staffing levels appear to have risen substantially. MAAGs appear to be more adequately funded by their health authorities than has previously been reported and many are actively seeking additional sources of funding. There is still large variation in levels of MAAG funding. Furthermore, funding is unrelated to the number of GPs or practices served. Security for MAAG staff appears to have been addressed in many areas, with 84% of MAAGs having at least one member of staff on a permanent employment contract. Many MAAGs are developing rolling programmes in an attempt to eliminate the short-sighted approach to the development of clinical audit that has existed since MAAGs were first set up.

Conclusion: Many MAAGs (with the obvious exception of those that have been dissolved) appear to be thriving without central direction or initiative. It is now evident that we were a little hasty in our concerns for the future of MAAGs beyond April 1996. It would seem that many organisations have taken the situation which arose two years ago as an opportunity to grow and develop in ways that may not have been possible within the confines of the Health Circular.

Improving care for people with osteoarthritis of the hip and 'knee : how has national policy for osteoarthritis been translated into service models in Australia?

There is strong rationale for improving care for people with chronic conditions, including osteoarthritis (OA). Successful implementation of healthcare reform requires new concepts and directions that are strongly supported by policy, new models of care (service redesign) and changes in day-to-day practice (healthcare provider and patient practice). In this paper we discuss the extent to which policy about management of OA of the hip and knee has been translated into new service models in Australia. A structured search of government and other key health websites in Australia was performed to identify policy, funding initiatives and new services models for managing OA of the hip and knee. This search was supported by a literature review. Musculoskeletal conditions were designated a National Health Priority in Australia in 2002. Under the Better Arthritis and Osteoporosis Care initiative, Australia has developed a national policy for OA care and national evidence-based clinical practice guidelines for management of OA of the hip and knee. Only two well described examples of new chronic disease management service models, the Osteoarthritis Clinical Pathway (OACP) model and the Osteoarthritis Hip and Knee Service (OAHKS) were identified. Primarily focused within acute care public hospital settings, these have been shown to be feasible and acceptable but have limited data on clinical impact and cost-effectiveness. While policy is extant, implementation has not been systematic and comprehensive. Clinicians have evidence-based recommendations for OA management but are poorly supported by service models to deliver these effectively and efficiently.

Clinical evaluation of long-term users of two contact lens care preservative systems

Purpose: To clinically evaluate long-term users of two different contact lens care preservative systems and to investigate whether prolonged use is associated with an increase in the prevalence of dry eye.

Methods: Eighty-nine wearers of group IV hydrogel or silicone hydrogel lenses participated in this one-visit, investigator-masked study. Subjects were required to have consistently used a polyhexamethylene biguanide (PHMB) or polyquaternium-1 (PQT) based solution for 2 years. Consistent use was defined as 80% for the past 2 years and 100% for the past year. Clinical assessments included: average and comfortable wear time; overall and end-of-day comfort; signs of dryness, discomfort, burning or stinging, grittiness or scratchiness and visual changes; non-invasive and fluorescein break-up-time; pre-ocular tear film lipids, tear meniscus height, Schirmer and fluorescein clearance tests; limbal and bulbar hyperemia; palpebral roughness; corneal and conjunctival staining; lens front surface wetting; and lens film deposits.

Results: Significantly more grittiness or scratchiness was reported by subjects using a PHMB-containing system (67% vs. 44%; P = 0.02). Palpebral roughness and hyperemia were significantly greater in the PHMB group wearing group IV lenses (P = 0.01 and P = 0.05, respectively). Corneal staining was significantly higher in the PHMB users in all four peripheral sectors (P < 0.01). Nasal and temporal conjunctival staining was also significantly higher for users of PHMB-containing systems (P < 0.05). Front surface lens wettability was significantly better for group IV PQT users compared to PHMB users (P = 0.008), with 84% vs. 72%, respectively, with lenses graded by the investigator as having good or excellent wettability. Significantly higher levels of lens front surface film deposits were noted with PHMB users (P = 0.007), with 58% of group IV lenses treated with PHMB compared with 38% of group IV lenses treated with PQT showing some lens front surface film deposition. No significant differences between the two preservative system groups were noted for the range of dry eye evaluations nor the remaining clinical assessments.

Conclusions: Differences in both ocular and lens characteristic were observed between long-term users of two preservative systems used in many contact lens multi-purpose solutions. The findings from this study did not support the hypothesis that prolonged use of PHMB-containing solutions leads to dry eye. Additional studies including a larger sample size and perhaps longer use of the systems could help to further elucidate differences in clinical performance between systems.
