Virtual Engagement of Families in the Intensive Care Unit During COVID-19: A Descriptive Survey of Family Members of Patients and Health Care Workers.

Introduction: Traditional face-to-face family member visits in the intensive care unit (ICU) are challenged during the coronavirus disease pandemic with time-critical visiting of the ICU patient being impossible. Objective: This study aimed to explore reported experiences and satisfaction surrounding the use of technology for virtual visits and virtual family meetings in the ICU setting. Two groups were surveyed: (1) family members of critically ill patients in the ICU and (2) health care workers caring for these patients. Design: The study, conducted in the 36-bed ICU of a speciality metropolitan acute care facility in Australia, used a pragmatic post-test survey design. Data were analyzed descriptively. Results: Of health care worker subjects, 106 completed the survey and the majority of communication episodes favored virtual visits (79.2%, n = 84). Of family member subjects, 69 completed the survey, with the majority participating in virtual family meetings (40.6%, n = 28). Both groups indicated satisfaction with virtual communication. Conclusions: We found virtual communication was positively received.

Pressure injury prevention practice in Australian intensive care units: A national cross-sectional survey.

INTRODUCTION: 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. MATERIALS AND METHODS: 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. RESULTS: 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). DISCUSSION AND CONCLUSION: 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.

Implementation and evaluation of multilayered pressure injury prevention strategies in an Australian intensive care unit setting.

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.

Pressure injury prevalence in Australian intensive care units: A secondary analysis.

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.

Incontinence-associated dermatitis: who is affected?

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.

Device-related pressure injuries in adult intensive care unit patients: An Australian and New Zealand point prevalence study.

BACKGROUND: Device-related pressure injuries (DRPIs) are an ongoing iatrogenic problem evident in intensive care unit (ICU) settings. Critically ill patients are at high risk of developing pressure injuries caused by devices. OBJECTIVE: The aim of the study was to determine the prevalence of DRPI in critically ill patients in intensive care and the location, stage, and attributable device of DRPI and describe the products and processes of care used to prevent these injuries. METHODS: This was a prospective, multicentre, cross-sectional point prevalence study of patients aged more than 16 years in Australian and New Zealand ICUs. The study was part of the Australian and New Zealand Intensive Care Society Clinical Trials Group Point Prevalence Program coordinated by The George Institute for Global Health. MAIN OUTCOME MEASURE: Identification of DRPI on the study day was the main outcome measure. RESULTS: Of the 624 patients included from 44 participating ICUs, 27 were found to have 35 identified DRPIs, giving a point prevalence DRPI rate of 4.3% (27/624). Study patients had a mean age of 59 years, and 60.3% were men. Patients with DRPI compared with patients without DRPI were significantly heavier (median: 92 kg versus 80 kg, respectively, p = 0.027), were less likely to survive the ICU (63.0% versus 85.9%, respectively, p = 0.015), had higher Acute Physiology and Chronic Health Evaluation II scores at admission to the ICU (median: 20 versus 16, respectively, p = 0.001), received mechanical ventilation more often (88.9% versus 43.5%, respectively, p < 0.001), and were more frequently diagnosed with respiratory conditions (37.0% versus 18.6%, respectively, p = 0.022). Processes of care activities were surveyed in 42 ICUs. Most DRPIs were attributed to endotracheal tubes and other respiratory devices. Forty-two ICUs reported processes of care to prevent DRPI, and just more than half of the participating sites (54.8%, 23/44) reported a dedicated ICU-based protocol for prevention of DRPI. CONCLUSION: DRPIs pose a burden on patients in the ICU. Our study showed a DRPI prevalence comparable with other studies. Prevention strategies targeting DRPI should be included in ICU-specific pressure injury prevention guidelines or protocols.

Efficacy of Incontinence-Associated Dermatitis Intervention for Patients in Intensive Care: An Open-Label Pilot Randomized Controlled Trial.

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.

Securement to prevent device-related pressure injuries in the intensive care unit: A randomised controlled feasibility study.

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.

Pressure injury development in critically ill patients with a cervical collar in situ: A retrospective longitudinal study.

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 < .001) were associated with pressure injury development. Patients with C-collar devices are a vulnerable group at risk for pressure injury development because of their immobility and length of ICU stay.

Exploring Incontinence-Associated Dermatitis in a Single Center Intensive Care Unit: A Longitudinal Point Prevalence Survey.

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 < .001), and Bristol Stool chart score (OR = 4.363, 95% CI: 2.091-9.106, P < .001). Patients with respiratory (OR = 3.657, 95% CI: 1.399-9.563, P = .008) and sepsis (OR = 3.230, 95% CI: 1.281-8.146, P = .013) diagnoses had increased odds of developing IAD. CONCLUSIONS: These data show the high variability of IAD prevalence over a 1-year period. Characteristics associated with the development of IAD in patients in the ICU included older age, longer lengths of ICU stay, incontinent of liquid feces, and having respiratory or sepsis diagnoses.

Manager, clinician or both? Nurse managers' engagement in clinical care activities.

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.

Understanding contextual barriers and enablers to pressure injury prevention practice in an Australian intensive care unit: An exploratory study.

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.

Mapping workforce configuration and operational models in Australian emergency departments: a national survey.

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.

Delineating the practice profile of advanced practice nursing: a cross-sectional survey using the modified strong model of advanced practice.

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.

Evaluation of a closed loop-blood sampling system in intensive care: A pilot randomised controlled trial. The ENCLOSE trial.

OBJECTIVE: 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. METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.

Exploring medical device-related pressure injuries in a single intensive care setting: A longitudinal point prevalence study.

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 intensive care unit 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 < 0.001), the length of time in the ICU (OR 1.05, 95% CI 1.02-1.09, p = 0.003), male sex, (OR 2.099, 95% CI 1.18-3.7, p = 0.012), and increased severity of illness score on admission (OR 1.044, 95% CI 1.01-1.09, p = 0.013). CONCLUSION: Device related pressure injuries are an all-too-common iatrogenic problem for this vulnerable patient cohort.

The work of nurse practitioners.

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.

Diagnostic accuracy of fine needle biopsy for metastatic melanoma and its implications for patient management.

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.

Diagnosis of metastatic melanoma by fine-needle biopsy: analysis of 2,204 cases.

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 asfibrosis, 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.

An interventional skin care protocol (InSPiRE) to reduce incontinence-associated dermatitis in critically ill patients in the intensive care unit: A before and after study.

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 768days of observation in the after/intervention group and 66 with 733days 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=<0.022). 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.
