Pressure injury (PI) is an ongoing problem for patients in intensive care units (ICUs). The aim of this study was to explore the nature and extent of PI prevention practices in Australian adult ICUs.An Australian multicentre, cross-sectional study was conducted via telephone interview using a structured survey instrument comprising six categories: workplace demographics, patient assessment, PI prevention strategies, medical devices, skin hygiene, and other health service strategies. Publicly funded adult ICUs, accredited with the College of Intensive Care Medicine, were surveyed. Data were analysed using descriptive statistics and chi-square tests for independence to explore associations according to geographical location.Of the 75 eligible ICUs, 70 responded (93% response rate). PI was considered problematic in two-thirds (68%) of all ICUs. Common PI prevention strategies included risk assessment and visual skin assessment conducted within at least 6 h of admission (70% and 73%, respectively), a structured repositioning regimen (90%), use of barrier products to protect the skin (94%), sacrum or heel prophylactic multilayered silicone foam dressings (88%), regular PI chart audits (96%), and PI quality improvement projects (90%). PI prevention rounding and safety huddles were used in 37% of ICUs, and 31% undertook PI research. Although most ICUs were supported by a facility-wide skin integrity service, it was more common in metropolitan ICUs than in rural and regional ICUs (p 0.001). Conversely, there was greater involvement of occupational therapists in PI prevention in rural or regional ICUs than in metropolitan ICUs (p = 0.026).This is the first study to provide a comprehensive description of PI prevention practices in Australian ICUs. Findings demonstrate that PI prevention practices, although nuanced in some areas to geographical location, are used in multiple and varied ways across ICUs.

Background: Pressure injuries are a ubiquitous, yet largely preventable, hospital acquired complication commonly seen in critically ill patients in the intensive care unit. Objectives: The objectives of this study were to implement targeted evidence-based pressure injury prevention strategies and evaluate their effect through measurement of patient pressure injury observations. Methods: A prospective multiphased design was used in the intensive care unit of an Australian tertiary referral hospital using three study periods (period 1, weeks 1–18; period 2, weeks 19–28; and period 3, weeks 29–52). The interventions included staff-focused interventions and patient-focused interventions, with the latter defined in a work unit guideline. Weekly visual observations of critically ill patients' skin integrity were conducted by trained research nurses over 52 weeks from November 2015 to November 2016. The primary outcome measure was a pressure injury of any stage, identified at the weekly observation, and the effect of the intervention was evaluated through logistic regression. Reporting rigour has been demonstrated using the Standards for Quality Improvement Reporting Excellence checklist. Results: Over the whole study, 15.4% (95% confidence interval [CI] = 12.6, 18.2%, 97/631) of patients developed a pressure injury, with the majority of these injuries (73.2%, 95% CI = 64.4%, 82.0%, 71/97) caused by medical devices. After adjustment for covariates known to influence hospital-acquired pressure injury development, pressure injury rates for period 3 compared with period 1 were reduced (odds ratio = 0.41, 95% CI = 0.20–0.97, p = 0.0126). Conclusions: We found the use of defined pressure injury prevention strategies targeted at both staff and patients reduced pressure injury prevalence.

Background Advanced practice nursing is recognised globally as central to meeting this community need. Whilst there is increasing recognition that advanced practice nurses should be educated to at least a master degree level, there is scant evidence on the influence of higher education on the practice profile of advanced practice nursing. Aim To investigate the relationship between level of education and domain practice scores of nurses in advanced practice roles. Methods The validated Advanced Practice Nursing Role Delineation (APRD) tool was used to measure the practice profile of advanced practice nurses at different postgraduate education levels, across five domains of nursing practice activities. A cross-sectional electronic survey of nurses was used. Findings APNs with higher degrees performed at a higher level across all five domains of the APRD tool compared to those who did not hold a higher degree. This was highly significant for the domains of Research and Leadership, followed by the Optimising Health Systems and Education domains, but not significant for the Direct Care domain. Discussion Questions are often raised about the benefits of investing in nurses’ education, particularly the need for a higher degree for advanced practice nurses. APNs with higher degrees have a different emphasis in their role activities than those without a higher degree. This difference could be significant given current global health challenges. Conclusion Higher education changes the practice profile of APNs. Those with higher education are more likely to be involved in research and leadership with knowledge integration across all practice domains.

Objective: Intensive care unit (ICU) patients possess multiple risk factors for developing loss of skin integrity, particularly incontinence-associated dermatitis (IAD). IAD is an inflammatory skin condition resulting from repeated and prolonged contact with urine, faeces or both. This study aimed to measure the incidence and clinical characteristics of adult ICU patients with IAD. Method: This was a prospective observational study conducted over three months in an adult ICU. Included patients were ≥18 years who experienced faecal incontinence during their intensive care admission. Patients were excluded if they had an ileostomy or colostomy, had IAD on admission, or were continent of urine and faeces. Skin inspections were performed every second day on all recruited patients by trained research nurses. Other data were collected from patient medical records. Results: A total of 37 patients took part in the study. Incidence of IAD was 35.1%; 13 patients who had incontinence developed IAD. The mean time to onset of IAD was 3.69 days, median 3 days (SD: 1.8, range: 2–8 days). Of the 13 patients who developed IAD, 12 (92.3%) patients were initially assessed as having category 1 IAD and one (7.7%) patient was initially assessed with category 2 IAD. Of the patients with category 1 IAD, one patient (7.7%) progressed to category 2 IAD severity. Conclusion: A larger sample is recommended to fully explore ICU patient characteristics and IAD development. The incidence of IAD in ICU patients was high at 35%, indicating this condition requires due consideration in ICU patients.

To test the feasibility of conducting a randomised controlled trial to evaluate the impact of a closed-loop blood sampling system and blood conservation bundle.Single site, parallel group, pilot randomised control trial comparing open system sampling to closed system sampling and conservation bundle aligned with national guidelines. Randomisation sequence was generated by an independent statistician and allocation concealment maintained via sealed opaque envelopes. The study setting was the general intensive care unit of a major metropolitan public hospital in Queensland, Australia. Participants were ≥ 18 years who had an arterial catheter inserted in intensive care. Main outcome measures included trial feasibility, blood sample loss, haematocrit (HCT) change, and packed red blood cell transfusion use.Eighty patients were randomised (n = 39 open group, n = 41 closed group). Characteristics in each group were equal at baseline with overall median age 60 years (IQR 48.6-70.4), 58 % male, and median APACHE II score 16 (IQR 11-22). The proportion of patients eligible was 29 % and missed eligible was 65 %. Otherwise, feasibility criteria were met with proportion of eligible patients agreeing to enrolment 99 %, 100 % of patients receiving allocated treatment; only 1 % of data missing. Analysis demonstrated a significant reduction in mean daily blood sample losses (open 32.7 (SD 1.58) mL vs closed 15.5 (SD 5.79) mL, t = -8.454, df = 78, p 0.001).A large, multi-site trial is feasible with enhanced eligibility criteria, increased recruitment support. The intervention reduced daily blood sample volumes and transfusion use. Further trials are required to provide both effectiveness and implementation outcomes.

OBJECTIVE To determine the feasibility of an adequately powered trial testing a long-acting cyanoacrylate skin protectant to prevent incontinence-associated dermatitis in critically ill patients. METHODS This open-label pilot randomized controlled feasibility study was conducted in the adult ICU of an Australian quaternary referral hospital. Patients were allocated to either an intervention group or a control group (usual care). The intervention was the application of a skin protectant (a durable, ultra-thin, transparent, waterproof, no-removal barrier film). Data collected by trained research nurses included demographic and clinical variables, skin assessment, and incontinence-associated dermatitis presence and severity. Data were analyzed using descriptive and inferential statistics. RESULTS Of the 799 patients screened, 85% were eliminated because of a short ICU stay or other exclusion criteria. The mean proportion of patients not meeting any of the exclusion criteria was 22% on each screening day. Protocol fidelity was followed for 90% of intervention participant study days. Retention of participants was 86% (31 participants out of 36), 15 in the intervention group and 16 in the control group. Enrolled patients had a mean age of 59 years, 50% were obese, 67% were male, and 36% were smokers. Two patients (11%) in the intervention group developed incontinence-associated dermatitis, compared with three (17%) in the control group. CONCLUSIONS This study reports no significant findings between the two groups. Difficulty in recruitment and feasibility issues might be overcome with changes to inclusion criteria and study design.

Trauma patients with a serious injury to the head or neck can remain immobilised with a cervical collar (C‐collar) device in situ and are subsequently exposed to device‐related skin integrity threats. This study aimed to determine the incidence and risk factors associated with the development of C‐collar‐related pressure injures (CRPIs) in an intensive care unit. This retrospective longitudinal cohort study was conducted in an Australian metropolitan intensive care unit. Following ethical approval, data from patients over 18 years, who received a C‐collar were retrieved over a 9‐year period. Chi square and t‐tests were used to identify variables associated with CRPI development. A logistic regression model was employed to analyse the risk factors. Data from 906 patients were analysed. Nine‐year pressure injury incidence was 16.9% (n = 154/906). Pressure injury development directly associated with a C‐collar increased by 33% with each repositioning episode (odds ratio 1.328, 95% confidence interval 1.024‐1.723, P = .033). Time in the C‐collar (10.4 to 2.5 days, P = .002) and length of stay in intensive care unit (ICU) (20.1 to 16.1 days, P

Background: Pressure injuries (PIs) are an enduring problem for patients in the intensive care unit (ICU) because of their vulnerability and numerous risk factors.Method: This study reports Australian data as a subset of data from an international 1-day point prevalence study of ICU-acquired PI in adult patients. Patients aged 18 years or older and admitted to the ICU on the study day were included. The outcome measure was the identification of a PI by direct visual skin assessment on the study day. Data collected included demographic data and clinical risk factors, PI location and stage, and PI prevention strategies used. Descriptive statistics were used to describe PI characteristics, and odds ratios (ORs) were used to identify factors associated with the development of a PI.Results: Data were collected from 288 patients from 16 Australian ICUs. ICU-acquired PI prevalence was 9.7%, with 40 PIs identified on 28 patients. Most PIs were of stage 1 and stage 2 (26/40, 65.0%). Half of the ICU-acquired PIs were found on the head and face. The odds of developing an ICU-acquired PI increased significantly with renal replacement therapy ( OR: 4.25, 95% confidence interval [CI]: 1.49-12.11), impaired mobility (OR: 3.13, 95% CI: 1.08-9.12), fastest respiratory rate (OR: 1.05 [per breath per minute], 95% CI: 1.00-1.10), longer stay in the ICU (OR: 1.04 [per day], 95% CI: 1.01-1.06), and mechanical ventilation on admission (OR: 0.36, CI: 0.14-0.91).Conclusion: This study found that Australian ICU-acquired PI prevalence was 9.7% and these PIs were associated with many risk factors. Targeted PI prevention strategies should be incorporated into routine prevention approaches to reduce the burden of PIs in the Australian adult ICU patient population.

OBJECTIVES To report longitudinal prevalence rates of device-related pressure injuries in critically ill adult patients in the intensive care unit and to explore the patient characteristics associated with the development of device related pressure injuries. RESEARCH DESIGN A prospective observational design where observations of patients' skin integrity were conducted on one day each week for 52 weeks. SETTING The study was conducted in the 36-bed ICU of a major metropolitan tertiary referral hospital in Queensland, Australia. The sample included all patients aged 18 years or older admitted to the intensive care unit before midnight on the day preceding the observation, with a medical device in situ. MAIN OUTCOME MEASURES The primary outcome measure was device related pressure injuries identified at the weekly observations and defined as a pressure injury found on the skin or mucous membrane with a history of medical device in use at the location of the injury. Patient demographic and clinical characteristics were recorded. RESULTS Over the study period, 11.3% (71/631) of patients developed at least one hospital-acquired DRPI. The most common devices associated with injury were nasogastric/nasojejunal tubes (41%) and endotracheal tubes (27%). Significant predictors of device related pressure injuries were the total number of devices (OR 1.230, 95% CI 1.09-1.38, p

Aim To explore the extent of Australian nurse managers' engagement in clinical care activities. Background Hybrid nurse manager roles lack clarity in the optimal balance between the clinical and other activities, resulting in stress and challenges in recruiting and retaining nurse managers. Methods In a national survey using the Advanced Practice Role Delineation tool, Australian nurses self-assessed their level of engagement in activities across five domains of nursing practice. The subset sample analysed comprised 2,758 registered nurses, 390 clinical (front-line) nurse managers and 43 organisational (middle) nurse managers. Median domain scores were compared with non-parametric tests of difference. Results Clinical nurse managers were in a hybrid role, reporting high levels of engagement across the domains. Lower scores observed for organisational nurse managers highlight the shift to strategy-focussed activities that occurs as nurses up the management hierarchy. Conclusions By indicating their engagement in the clinical care domain, respondents demonstrated that clinically focused activities were not entirely lost from either front-line or middle-management roles. Implications for nursing management Nurse managers equipped with clinical and management skills, and allowed time to remain engage in clinical care activities are critical for patient-centred and cost-effective care in today's complex health care environments.

Medical device-related pressure injuries are the most common cause of pressure injuries within the intensive care unit, in particular those caused by nasogastric tubes and endotracheal tubes. There are several known methods, which can alleviate the pressure of these devices on the skin surface to reduce the rate of these injuries. To determine the feasibility of conducting a larger, adequately powered trial testing, several clinically effective interventions to reduce the incidence of medical device-related pressure injuries caused by these devices. Patients were recruited into both study arms and received one of three different methods of skin protection for both arms. Outcome measures included fidelity to the processes of care protocol, recruitment potential, and the number of medical device-related pressure injuries. Recruitment (n = 87) was slower than expected with less than 10% of screened potential patients available for enrolment. Fidelity to the process of care for each subgroup was variable with better adherence in the nasogastric tube arm compared to the endotracheal tube arm. This feasibility study has revealed concerns about the intervention designs and effectiveness as well as challenges for the adherence of the nursing staff to the protocol.

© 2017 International Council of Nurses Aim: To identify the practice patterns of the Australian registered nurse workforce according to position title and to map these disparate titles across all jurisdictions of the country. Introduction: Effective nursing workforce planning can contribute to improved patient care and increased effectiveness and efficiency of healthcare systems. Background: The prevailing approach to nursing workforce planning focuses on number of nursing staff needed in relation to the number of patients. The level of expertise and skill mix of registered nurses as a variable in workforce planning is rarely considered. Methods: A national cross-sectional electronic survey of registered nurses in Australia was conducted using the validated Advanced Practice Role Delineation tool developed from the Strong Model of Advanced Practice. The study involved a sample of 5599 registered nurses. Results: Sixty-six nursing position titles nationally were mapped using cluster analysis technique and gave rise to seven clusters of equivalent Australian jurisdictional nursing position titles and practice profiles. Discussion: Effective workforce policy and planning is reliant upon access to reliable evidence. This research is an international first in that it has provided comprehensive knowledge of the clinical level and practice profiles of a national nursing workforce. Implications for nursing policy: Effective, patient-centred workforce planning must consider both the numerical and expertise mix of a nursing workforce. This research provides Australian health service and policy planners with evidence-base knowledge of the nursing workforce. Internationally, this research establishes a platform from which to develop validated tools and established processes to support replication of this research.

Purpose: The purpose of this study was to provide longitudinal prevalence rates of incontinence-associated dermatitis (IAD) in patients in an intensive care unit (ICU) and to identify patient characteristics associated with IAD development. Design: Prospective observational. Subjects and Setting: The sample comprised 351 patients aged 18 years and older in a major metropolitan public hospital ICU in Queensland, Australia. Methods: All consenting, eligible participants at risk of developing IAD underwent weekly skin inspections to determine the presence of IAD. Data were collected weekly for 52 consecutive weeks. Descriptive statistics described the study sample and logistic regression analysis was used to identify patient characteristics associated with development of IAD. Results: The weekly IAD prevalence ranged between 0% and 70%, with IAD developing in 17% (n = 59/351) of ICU patients. The odds of IAD developing increased statistically significantly with increasing age (odds ratio [OR]: 1.029, 95% confidence interval [CI]: 1.005-1.054, P =.016), time in the ICU (OR = 1.104; 95% CI: 1.063-1.147, P

ObjectivesTo evaluate the impact of nurse practitioner (NP) service in Australian public hospital emergency departments (EDs) on service and patient safety and quality indicators.Design and settingCohort study comprising ED presentations (July 2013–June 2014) for a random sample of hospitals, stratified by state/territory and metropolitan versus non-metropolitan location; and a retrospective medical record audit of ED re-presentations.MethodsService indicator data (patient waiting times for Australasian Triage Scale categories 2, 3, 4 and 5; number of patients who did not-wait; length of ED stay for non-admitted patients) were compared between EDs with and without NPs using logistic regression and Cox proportional hazards regression, adjusting for hospital and patient characteristics and correlation of outcomes within hospitals. Safety and quality indicator data (rates of ED unplanned re-presentations) for a random subset of re-presentations were compared using Poisson regression.ResultsOf 66 EDs, 55 (83%) provided service indicator data on 2 463 543 ED patient episodes while 58 (88%) provided safety and quality indicator data on 2853 ED re-presentations. EDs with NPs had significantly (pConclusionsEDs with NPs had statistically significantly lower performance for service indicators. However, these findings should be treated with caution. NPs are relatively new in the ED workforce and low NP numbers, staffing patterns and still-evolving roles may limit their impact on service indicators. Further research is needed to explain the dichotomy between the benefits of NPs demonstrated in individual clinical outcomes research and these macro system-wide observations.

Objective Hospital emergency departments (ED) in Australia and internationally have been experiencing increased demand, resulting in reduced hospital quality, impaired access and adverse health outcomes. Effective evaluation of new ED service models and their effect on outcomes is reliant on baseline measures of the staffing configuration and organisational characteristics of the EDs being studied. The aim of the present study was to comprehensively measure these variables in Australian EDs. Methods Australian hospital EDs with 24-h medical and nursing cover were identified and invited to participate in the study. Telephone interviews were conducted with nursing or medical department managers to collect data related to hospital characteristics, ED workforce and training and ED service and operational models. Results Surveys were completed in 87% of the population sample (n = 135). Metropolitan EDs were significantly more likely to retain higher full-time equivalents (FTEs) in several medical (staff specialist, registrar, resident and intern) and nursing (nurse practitioner (NP), nurse educator, nurse unit manager and registered nurse) positions. NPs were employed by 52% of Australian EDs overall, but this ranged from 40% to 75% depending on jurisdiction. The most commonly used operational models were FastTrack teams (72% of EDs), short-stay/observational unit (59%) and patient liaison models for aged care (84%) and mental health (61%). EDs that employed NPs were significantly more likely to use FastTrack (P = 0.002). Allied health services most frequently available within these EDs were radiology (60%), social work (69%), physiotherapy (70%) and pharmacy (65%). Conclusions The present study has established a baseline measure of the staffing configuration and organisational characteristics of Australian EDs. What is known about the topic? EDs are overcrowded due, in part, to the combined effect of increased service demand and access block. Innovative service and workforce models have been implemented by health departments aiming to improve service and performance. National uptake of these service and workforce innovations is unknown. What does this paper add? The present study is the most comprehensive to date profiling Australian EDs covering hospital characteristics, workforce configuration, operational models and NP service patterns and practice. What are the implications for practitioners? Information from the present study will assist health service planners to evaluate workforce and service reform models, and to monitor trends in emergency service development.

Background Skin integrity management is often a low clinical priority in the intensive care environment, possibly resulting in high pressure injury (PI) prevalence. This article reports the results of the first phase of a multiphased project, “Translating evidence-based pressure injury prevention strategies to the intensive care environment (SUSTAIN study)”. The SUSTAIN study used a research translation framework to guide the assessment of research uptake, development, and monitoring of translational strategies to reduce PIs. Objective The objective was to assess the enablers and barriers to research translation of evidence-based skin integrity management in one Australian tertiary referral intensive care unit (ICU). Methods This exploratory study was conducted in an Australian metropolitan tertiary ICU on a sample of 204 registered nurses. Data were collected using (i) a descriptive cross-sectional cohort survey of barriers, enablers, and attitudes to PI prevention, (ii) a cross-sectional survey of PI knowledge, and (iii) focus groups to understand the local contextual factors impacting registered nurses' PI prevention practice. Results Participants reported a moderate to high ability to rise above barriers in PI prevention, a positive attitude towards PI prevention, and considered this a priority in their care of patients. High patient acuity emerged as a barrier to implementing timely PI prevention strategies. In the knowledge, test participants with postgraduate qualifications answered more statements correctly. Focus group data revealed four themes: (i) team ICU, (ii) processes of care, (iii) education for consistency, and (iv) the patient. Conclusions It is essential that evidence-based PI prevention strategies are provided in the intensive care environment. Our findings indicate that despite positive attitudes and sound knowledge levels, high patient acuity is a significant barrier to evidence implementation.

Summary Aim This study aimed to test the effectiveness of a bundle combining best available evidence to reduce the incidence of incontinence-associated dermatitis occurrences in critically ill patients. Methods The study used a before and after design and was conducted in an adult intensive care unit of an Australian quartenary referral hospital. Data, collected by trained research nurses, included demographic and clinical variables, skin assessment, incontinence-associated dermatitis presence and severity. Data were analysed using descriptive and inferential statistics. Results Of the 207 patients enrolled, 146 patients were mechanically ventilated and incontinent thus eligible for analysis, 80 with 768 days of observation in the after/intervention group and 66 with 733 days of observation in the before group. Most patients were men, mean age 53 years. Groups were similar on demographic variables. Incontinence-associated dermatitis incidence was lower in the intervention group (15%; 12/80) compared to the control group (32%; 21/66) (p = 0.016). Incontinence-associated dermatitis events developed later in the intensive care unit stay in the intervention group (Logrank = 5.2, p = Conclusion This study demonstrated that the use of a bundle combining best available evidence reduced the incidence and delayed the development of incontinence-associated dermatitis occurrences in critically ill patients. Systematic ongoing patient assessments, combined with tailored prevention measures are central to preventing incontinence-associated dermatitis in this vulnerable patient group.

Aim: This paper is a report of a study of variations in the pattern of nurse practitioner work in a range of service fields and geographical locations, across direct patient care, indirect patient care and service-related activities. Background: The nurse practitioner role has been implemented internationally as a service reform model to improve the access and timeliness of health care. There is a substantial body of research into the nurse practitioner role and service outcomes, but scant information on the pattern of nurse practitioner work and how this is influenced by different service models. Methods: We used work sampling methods. Data were collected between July 2008 and January 2009. Observations were recorded from a random sample of 30 nurse practitioners at 10-minute intervals in 2-hour blocks randomly generated to cover 2 weeks of work time from a sampling frame of 6 weeks. Results: A total of 12,189 individual observations were conducted with nurse practitioners across Australia. Thirty individual activities were identified as describing nurse practitioner work, and these were distributed across three categories. Direct care accounted for 36·1% of how nurse practitioners spend their time, indirect care accounted for 32·0% and service-related activities made up 31·9%. Conclusion: These findings provide useful baseline data for evaluation of nurse practitioner positions and the service effect of these positions. However, the study also raises questions about the best use of nurse practitioner time and the influences of barriers to and facilitators of this model of service innovation. © 2010 The Authors.

Background The use of fine needle biopsy (FNB) for the diagnosis of metastatic melanoma can lead to the early removal and treatment of metastases, reduce the frequency of unnecessary surgery, and facilitate the staging of patients enrolled in clinical trials of adjuvant therapies. In this study, the accuracy of FNB for the diagnosis of metastatic melanoma was investigated. Methods A retrospective cohort study was performed with 2204 consecutive FNBs performed on 1416 patients known or suspected to have metastatic melanoma. Almost three-quarters (1582) of these FNBs were verified by either histopathologic diagnosis following surgical resection or clinical follow-up. Results FNB for metastatic melanoma was found to have an overall sensitivity of 92.1% and a specificity of 99.2%, with 69 false-negative and 5 false-positive findings identified. The sensitivity of the procedure was found to be influenced by six factors. The use of immunostains, reporting of the specimen by a cytopathologist who had reported >500 cases, lesions located in the skin and subcutis, and patients with ulcerated primary melanomas were factors associated with a significant improvement in the sensitivity of the test. However, FNBs performed in masses located in lymph nodes of the axilla and FNBs that required more than one needle pass to obtain a sample were far more likely to result in false-negative results. Conclusions FNB is a rapid, accurate, and clinically useful technique for the assessment of disease status in patients with suspected metastatic melanoma.

Fine-needle biopsy (FNB) has been reported as a rapid, minimally invasive technique for the diagnosis of metastatic melanoma. The diagnostic accuracy of FNB was assessed in a consecutive series of 2,204 FNBs of clinically suspicious lesions from patients with previous primary melanomas treated at the Sydney Melanoma Unit, Sydney, Australia, between January 1992 and December 2002. The sensitivity and specificity of FNB were 96.3% and 98.9%, respectively. There were 5 false-positive cases (0.6%), which were verified as metastatic adenocarcinoma (3 cases) or reactive processes (organizing hematoma and chronic osteomyelitis, 1 each). False-negative diagnoses (6.7% of cases) were associated with a variety of clinicopathologic factors, including difficult-to-access anatomic sites (eg, high axilla or deep inguinal), small lesions, and lesional characteristics such as fibrosis, necrosis, or cystic change. FNB is a highly accurate, rapid, and cost-effective procedure for the diagnosis of metastatic melanoma and should be considered as the initial diagnostic procedure of choice in patients with melanoma with clinically suspected metastases. Melanoma is a common tumor, accounting for approximately 3% of all cancers. 1 It is a major cause of mortality and has a major impact on the most productive years of life because it is often diagnosed in relatively young people. 2 Survival in patients with melanoma is related to the stage of the disease at diagnosis, and patients with metastatic melanoma have much poorer survival than those without metastases. 3-7 Melanoma

Background The size and flexibility of the nursing workforce has positioned nursing as central to the goals of health service improvement. Nursing's response to meeting these goals has resulted in proliferation of advanced practice nursing with a confusing array of practice profiles, titles and roles. Whilst numerous models and definitions of advanced practice nursing have been developed there is scant published research of significant scope that supports these models. Consequently there is an ongoing call in the literature for clarity and stability in nomenclature, and confusion in the health industry on how to optimise the utility of advanced practice nursing. Objectives To identify and delineate advanced practice from other levels of nursing practice through examination of a national nursing workforce. Design A cross-sectional electronic survey of nurses using the validated Advanced Practice Role Delineation tool based on the Strong Model of Advanced Practice. Participants Study participants were registered nurses employed in a clinical service environment across all states and territories of Australia. Methods A sample of 5662 registered nurses participated in the study. Domain means for each participant were calculated then means for nursing position titles were calculated. Position titles were grouped by delineation and were compared with one-way analysis of variance on domain means. The alpha for all tests was set at 0.05. Significant effects were examined with Scheffe post hoc comparisons to control for Type 1 error. Results The survey tool was able to identify position titles where nurses were practicing at an advanced level and to delineate this cohort from other levels of nursing practice, including nurse practitioner. The results show that nurses who practice at an advanced level are characterised by high mean scores across all Domains of the Strong Model of Advanced Practice. The mean scores of advanced practice nurses were significantly different from nurse practitioners in the Direct Care Domain and significantly different from other levels of nurse across all domains. Conclusions The study results show that the nurse practitioner, advanced practice nurse and foundation level registered nurse have different patterns of practice and the Advanced Practice Role Delineation tool has the capacity to clearly delineate and define advanced practice nursing. These findings make a significant contribution to the international debate and show that the profession can now identify what is and what is not advanced practice in nursing.

Purpose To test an interventional patient skin integrity bundle, the InSPiRE protocol, for reducing pressure injuries in critically ill patients in an Australian adult intensive care unit. Methods Before and after design: patients receiving the intervention (InSPiRE protocol) were compared with a similar control group who received standard care. Data collected included demographic and clinical variables, skin assessment, presence and stage of pressure injuries, and score on the Sequential Organ Failure Assessment (SOFA). Results Overall, 207 patients were enrolled, 105 in the intervention group and 102 in the control group. Most patients were men (mean age, 55 years). The groups were similar on major demographic variables (age, SOFA scores, intensive care unit stay). Cumulative incidence of pressure injuries was significantly lower in the intervention group (18.1%) than in the control group (30.4%) for skin injuries ( [Formula: see text], P = .04) and mucous injuries (t = 3.27, P ≤ .001). Significantly fewer pressure injuries developed over time in the intervention group (log rank = 11.842, df = 1, P ≤ .001) and intervention patients had fewer skin injuries (> 3 pressure injuries/patient = 1/105) than did control patients (> 3 pressure injuries/patient = 10/102; P = .02). Conclusion The intervention group, receiving the InSPiRE protocol, had a lower cumulative incidence of pressure injuries, and fewer and less severe pressure injuries that developed over time. Systematic and ongoing assessment of the patient's skin and risk for pressure injuries as well as implementation of tailored prevention measures are central to preventing pressure injuries.

Isolated limb perfusion (ILP) with cytotoxic agents is a remarkably effective but complex technique used to treat locally recurrent and metastatic melanoma confined to a limb. Isolated limb infusion (ILI), essentially a low-flow ILP performed without oxygenation via percutaneous catheters, has been developed as a simpler alternative.The outcome in 135 patients treated by ILI was reviewed.The overall response rate in the treated limb was 85% (complete response [CR] rate 41%, partial response rate 44%). Median response duration response was 16 months (24 months for patients with CR). Median patient survival was 34 months. In those with a CR, the median survival was 42 months. CR rate and survival time decreased with increasing disease stage. Patients aged70 years had a better overall response than younger patients. On multivariate analysis, factors associated with an improved outcome were a lower stage of disease, a final limb temperature37.8 degrees C, and a tourniquet time40 minutes.The frequency and duration of responses after ILI were comparable to those achieved by conventional ILP. The ILI technique is particularly useful for older patients who might not be considered suitable for conventional ILP.

This study sought to use a microdialysis technique to relate clinical and biochemical responses to the time course of melphalan concentrations in the subcutaneous interstitial space and in tumour tissue (melanoma, malignant fibrous histiocytoma, Merkel cell tumour and osteosarcoma) in patients undergoing regional chemotherapy by Isolated Limb Infusion (ILI). 19 patients undergoing ILI for treatment of various limb malignancies were monitored for intra-operative melphalan concentrations in plasma and, using microdialysis, in subcutaneous and tumour tissues. Peak and mean concentrations of melphalan were significantly higher in plasma than in subcutaneous or tumour microdialysate. There was no significant difference between drug peak and mean concentrations in interstitial and tumour tissue, indicating that there was no preferential uptake of melphalan into the tumours. The time course of melphalan in the microdialysate could be described by a pharmacokinetic model which assumed melphalan distributed from the plasma into the interstitial space. The model also accounted for the vascular dispersion of melphalan in the limb. Tumour response in the whole group to treatment was partial response: 53.8% (n= 7); complete response: 33.3% (n= 5); no response: 6.7% (n= 1). There was a significant association between tumour response and melphalan concentrations measured over time in subcutaneous microdialysate (P< 0.01). No significant relationship existed between the severity of toxic reactions in the limb or peak plasma creatine phosphokinase levels and peak melphalan microdialysate or plasma concentrations. It is concluded that microdialysis is a technique well suited for measuring concentrations of cytotoxic drug during ILI. The possibility of predicting actual concentrations of cytotoxic drug in the limb during ILI using our model opens an opportunity for improved drug dose calculation. The combination of predicting tissue concentrations and monitoring in microdialysate of subcutaneous tissue could help optimise ILI with regard to post-operative limb morbidity and tumour response. © 2001 Cancer Research Campaign http://www.bjcancer.com

Aims To test a model that delineates advanced practice nursing from the practice profile of other nursing roles and titles. Background There is extensive literature on advanced practice reporting the importance of this level of nursing to contemporary health service and patient outcomes. Literature also reports confusion and ambiguity associated with advanced practice nursing. Several countries have regulation and delineation for the nurse practitioner, but there is less clarity in definition and service focus of other advanced practice nursing roles. Design A statewide survey. Methods Using the modified Strong Model of Advanced Practice Role Delineation tool, a survey was conducted in 2009 with a random sample of registered nurses/midwives from government facilities in Queensland, Australia. Analysis of variance compared total and subscale scores across groups according to grade. Linear, stepwise multiple regression analysis examined factors influencing advanced practice nursing activities across all domains. Results There were important differences according to grade in mean scores for total activities in all domains of advanced practice nursing. Nurses working in advanced practice roles (excluding nurse practitioners) performed more activities across most advanced practice domains. Regression analysis indicated that working in clinical advanced practice nursing roles with higher levels of education were strong predictors of advanced practice activities overall. Conclusion Essential and appropriate use of advanced practice nurses requires clarity in defining roles and practice levels. This research delineated nursing work according to grade and level of practice, further validating the tool for the Queensland context and providing operational information for assigning innovative nursing service.

Postburn itch is reported to affect up to 87% of the burn population. Although treatments for postburn itch are multimodal, they remain consistently ineffective. However, recent anecdotal evidence from several outpatients at a tertiary referral hospital suggests that a cream combining beeswax and several herbal oils may be effective in the minimization of postburn itch. The aim of this study was to test the efficacy of beeswax and herbal oil cream against the standard treatment of aqueous cream in the provision of relief from the symptoms of postburn itch. A randomized controlled trial compared two groups using a visual analog scale, frequency of cream application, itch recurrence after cream application, use of antipruritic medications, and sleep disturbance to determine the effect of itch severity and duration. Fifty-two participants were enrolled in the study (84% male) with a mean age of 35 years (SD = 16) and mean burn TBSA of 7.2% (SD = 7.7). Study results found that the beeswax and herbal oil cream reduce itch after application more frequently than aqueous cream (P = .001). In addition, when managed with beeswax and herbal oil cream, participants found that their itch recurred later (P

Introduction: Pressure injuries (PrI) are a common, preventable, adverse event. PrIs cause harm, pain and infections to patients, adversely effect recovery, and contribute to disease burden and ongoing healthcare costs. Objectives: It was hypothesised that, when compared with patients who receive standard skin care, patients who receive the InSPiRE protocol: 1. will have a lower incidence of PrI; and 2. develop PrIs later in their intensive care unit stay. Methods: The study used a prospective cohort design. The group of patients receiving the intervention (InSPiRE protocol) was compared with a similar control group who received standard care. The study was conducted over 12-months in the adult ICU of an Australian metropolitan tertiary hospital. Data collected included demographic and clinical variables, skin assessment, PrI presence and stage, and illness severity score. Following ethical approval, employed research nurses were trained in clinical assessment, data collection tools and recruitment processes. Results: Of 207 patients enrolled, 105 were in the intervention group and 102 in the control group. Most patients were men, mean age 55 years. The groups were similar on major demographic variables. PrI incidence was significantly different between the intervention group (18.1%, 19/105 patients) and control group (30.4%, 31/102 patients) (χ2 = 4.271, p = 0.039). The intervention significantly lowered the number of PrI events developing over time (Logrank [Mantel–Cox] = 11.842, p = 0.001). Conclusions: The InSPiRE protocol resulted in significant reductions in the cumulative incidence and time to occurrence of PrIs. The protocol was tailored to the ICU population and assisted registered nurses in delivering quality-focused patient care.

Fine-needle biopsy (FNB) is commonly used in the investigation of patients with a history of melanoma who present with possible metastatic disease. Non-melanoma malignancies (NMM) are common in the general population and not infrequent in patients with melanoma. Such tumors may be difficult to distinguish from metastatic melanoma on FNB. We sought to determine the types of NMMs that occur in melanoma patients, to document the frequency with which they were diagnosed by FNB, and to highlight potential pitfalls in cytologic diagnosis. NMMs occurring in 1416 consecutive melanoma patients who underwent FNB of 2204 clinically suspicious lesions between 1992 and 2002 at a single center were reviewed and analyzed. The sites of FNB included lymph nodes (36.9%), skin and subcutis (25.1%), visceral locations (17.9%), and other sites (20.0%). Of the 1416 melanoma patients investigated by FNB, 116 (8.2%) had a metachronous or synchronous NMM; the NMM was diagnosed by the FNB in 17 (14.7%) patients. The most common NMMs were epithelial tumors (69.4%, most commonly carcinomas of large bowel, breast and prostate) and hematologic malignancies (21.8%). As NMMs are not infrequent in patients with melanoma, they should always be considered in the differential diagnosis of clinically suspicious masses in patients with a history of melanoma, as well as in patients at high risk of melanoma. Careful assessment of the FNB cytologic features and directed use of ancillary studies should enable accurate diagnosis in most cases and facilitate appropriate patient management.

Background: In most major melanoma treatment centers, sentinel node biopsy (SNB), with complete regional lymph node dissection when a positive sentinel node is found, has now replaced elective lymph node dissection (ELND) for patients with primary cutaneous melanomas who are considered to be at moderate to high risk of nodal recurrence. As for ELND, however, no overall survival benefit for the SNB procedure has yet been demonstrated. The objective of this study was to compare the nodal staging accuracy and duration of survival for SNB and ELND. Methods: A retrospective cohort study was conducted among patients with American Joint Committee on Cancer (AJCC) stage II disease treated at a single center between 1983 and 2000 with either SNB (n = 672) or ELND (n = 793). Multivariate analyses were performed using the logistic regression model for nodal staging accuracy and Cox’s proportional hazards regression model for survival. Results: Patient factors that influenced nodal positivity included age, Breslow thickness, ulceration, head or neck primary, and operation type (SNB or ELND). SNB was superior to ELND in the detection of micrometastases (odds ratio 1.23, 95% CI, 1.06 – 1.43) but operation type did not influence survival (P = .24). Conclusions: Sentinel node biopsy identified more nodal micrometastases than ELND but did not influence survival, although complete regional node dissection was performed in all patients who were SNB positive. This increase in staging accuracy likely results from the reliable identification of the appropriate lymph node field by preoperative lymphoscintigraphy, along with more detailed pathologic examination of the nodes removed by SNB.

Contains fulltext : 57654.pdf (Publisher’s version ) (Closed access) BACKGROUND: Isolated limb infusion (ILI) is a simple yet effective alternative to conventional isolated limb perfusion for the treatment of advanced melanoma of the extremities. PATIENTS AND METHODS: The study group comprised 13 patients with very advanced limb disease who had failed to achieve a satisfactory response to one or more ILIs with melphalan, and in whom amputation was the only other realistic treatment option. The aim of this study was to evaluate the efficacy and toxicity of ILI with fotemustine after systemic chemosensitisation with dacarbazine (DTIC). RESULTS: Complete remission was achieved in four patients and partial remission in eight patients, with a median response duration of 3 months. Limb salvage was achieved in five of 12 assessable patients (42%). Limb toxicity peaked 9 days after ILI; two patients experienced Wieberdink grade IV (severe) toxicity and four patients had grade V toxicity (requiring early amputation). CONCLUSIONS: ILI with fotemustine after DTIC chemosensitisation can be successful when gross limb disease has not been controlled by one or more ILIs with melphalan. However, it cannot be recommended as a routine method of treatment for advanced melanoma of the extremities because of the high incidence of severe limb toxicity.

Objective To calculate survival probabilities of patients with 3 or more multiple primary melanomas. Design Retrospective cohort study of patients with primary melanoma. Setting Patients treated at a tertiary center (Sydney Melanoma Unit, Sydney, Australia) for stage I or II melanoma between 1983 and 1999. Patients From 5250 patients with primary melanoma, 264 (5.0%) had double and 34 (0.6%) had 3 or more primary melanoma lesions. Results The estimated 10-year risk for developing a second primary melanoma in these patients was 12.7% (95% confidence interval [CI], 10.5%-14.9%). For those patients who had 2 primary melanomas, the estimated 10-year risk of developing a third lesion was 27.7% (95% CI, 14.7%-36.7%). When controlling for known prognostic factors in a proportional hazards regression model, the number of primary melanomas was a significant favorable survival predictor when the thickest or the first tumor was modeled. In patients with 3 or more primary melanomas, 31 survived when 25 (95% CI, 22-27) were expected to survive. Patients who survive longer may have the opportunity to develop multiple primary melanomas. Patients who encountered all their primary lesions within 2 years may not be subject to this bias. Within the 3 or more melanoma set, 11 patients had all primary melanomas within 2 years. All survived, whereas 9 (95% CI, 8-10) were expected to survive. Conclusions Patients with 3 or more primary melanoma lesions survive longer than anticipated. Such enhanced survival in patients with 3 or more primary melanomas may be consistent with observations of an "immunization effect" in animals inoculated with multiple tumors.
