Optimising safety, fidelity and usability of an Intelligent Clinical Support Tool (ICST) for acute hospital care: an Australian case Study using a multi-method Delphi process

This research focuses on a major health priority for Australia by addressing existing gaps in the implementation of nursing informatics solutions in healthcare. It serves to inform the successful deployment of IT solutions designed to support patient-centered, frontline acute healthcare delivery by multidisciplinary care teams. The outcomes can guide future evaluations of the contribution of IT solutions to the efficiency, safety and quality of care delivery in acute hospital settings.

The education needs of caregivers of stroke survivors in acute and community settings

Stroke is a major cause of chronic illness in Australia, where it is estimated that between 200,000 and 250,000 people live with disabilities due to stroke. Given stroke's effect on survivors and the accompanying burden on caregivers, attention should be given to addressing the needs of caregivers of stroke survivors because they are central to supporting survivors living in the community. Research has shown that the information needs of caregivers are not being met across healthcare settings. Thus, some attention must be given to the development of educational materials that address caregiver needs. In this study we interviewed caregivers to determine their perspectives on support and educational needs at two different stages in the recovery of the stroke survivor: the acute hospital and the community. Despite a high level of uncertainty among caregivers in the acute and community settings, limited information was provided to assist them in their new role. A multifaceted approach would involve the development and implementation of specifically designed educational materials for caregivers, the use of a tool such as a patient-held record to assist in and improve the continuity and communication of care, and the provision of ongoing support from a stroke nurse practitioner who would follow stroke survivors from the acute setting to the community. This approach should be evaluated so that the important issue of addressing caregiver needs is given its due attention.

Economic evaluation of Australian stroke services: a prospective, multicenter study comparing dedicated stroke units with other care modalities

Background and Purpose: Level I evidence from randomized controlled trials demonstrates that the model of hospital care influences stroke outcomes; however, the economic evaluation of such is limited. An economic appraisal of 3 acute stroke care models was facilitated through the Stroke Care Outcomes: Providing Effective Services (SCOPES) study in Melbourne, Australia. The aim was to describe resource use up to 28 weeks poststroke for each model and examine the cost-effectiveness of stroke care units (SCUs). Methods: A prospective, multicenter, cohort study design was used. Costs and outcomes of stroke patients receiving 100% treatment in 1 of 3 inpatient care models (SCUs, mobile service, conventional care) were compared. Health-sector resource use up to 28 weeks was measured in 1999. Outcomes were thorough adherence to a suite of important clinical processes and the number of severe inpatient complications. Results: The sample comprised 395 participants (mean age 73 [SD 14], 77% first-ever strokes, males 53%). When compared with conventional care (n=84), costs for mobile service (n=209) were significantly higher (P=0.024), but borderline for SCU (n=102, P=0.08; $AUD12 251; $AUD15 903; $AUD15 383 respectively). This was primarily explained by the greater use of specialist medical services. The incremental cost-effectiveness of SCUs over conventional care was $AUD9867 per patient achieving thorough adherence to clinical processes and $AUD16 372 per patient with severe complications avoided, based on costs to 28 weeks. Conclusions: Although acute SCU costs are generally higher, they are more cost-effective than either mobile service or conventional care.

Will he get back to normal? survival and functional status after intensive care therapy

The study aim was to address healthcare workers’ and patients’ questions about the likely level of recovery at 6 months of patients admitted to an Australian intensive care unit (ICU). Ninety-three consecutive, eligible adults were identified and followed prospectively. Severity of illness on admission was assessed using Acute Physiological and Chronic Health Evaluation (APACHE II), while functional status at 6 months was evaluated using the Sickness Impact Profile (SIP). Cumulative mortality was 25%. Admission severity of illness was associated with survival at 6 months (P≤0.001). Fifty-one (78%) of the 70 survivors were interviewed. Admission severity of illness scores correlated with functional status at 6 months (r=0.34, P=0.01), a finding reported in only one other study. More than half of those interviewed had returned to near pre-admission functional status. Those with poor functional status included high proportions of people with chronic illness and head injury. Overall, physical recovery was more complete than psychosocial recovery. The findings provide useful information for addressing questions relating to physical and psychosocial recovery, appetite, sleep patterns and return to work post discharge.

Discharge planning: from the acute sector for people over the age of 65

This paper reports the findings relating to discharge planning from a larger study (Hegney et al 2001) that aimed to investigate options to improve care co-ordination between the aged, community, acute and primary care sectors for the elderly residents of a large provincial town. The data, which were collected from a wide variety of aged care stakeholders in the region, are consistent with previous Australian studies. First, it appears that inappropriate discharge from acute hospitals occurs in Toowoomba because there is a perceived lack of information regarding the available community care options and a lack of suitable models to support people's care needs within their own homes. Second, inappropriate discharge practices from acute hospitals occur due to a lack of knowledge and communication on the part of health professionals employed in these settings with regard to the on- going health care needs of elderly people. Third, there is little discharge planning occurring that includes the general practitioner in post-discharge care. Finally, inappropriate discharge can also be attributed to the lack of sub-acute/step-down/rehabilitation options and long waiting lists for community home care services in the region.

Depression, anxiety and stress in women following acute coronary syndrome: implications for secondary prevention

Objective
To document incidence of depression, anxiety, and stress in women more than 6 months following an acute coronary syndrome.

Design
Participants were identified from a coronary care unit database. The Depression Anxiety Stress Scales 21 (DASS 21) was sent to potential participants via postal survey.

Setting
A metropolitan teaching hospital in Melbourne, Australia.

Participants
The cohort of women was aged between 55 and 70 years. They had been admitted to hospital with a diagnosis of acute coronary syndrome (ACS) between 6 and 14 months prior to participating in this study.

Main outcome measures
Scores on Depression, Anxiety, and Stress Scale (DASS 21).

Results
Of the 117 posted questionnaires, 39 women with a mean age of 63 (S.D. 4.97) responded to the survey, representing a response rate of 33.3%. Most participants scored within normal levels of depression (66.7%), anxiety (60.5%), and stress (70.3%), however, mild to extremely severe levels of each construct (33.4%, 39.6%, and 29.7%, respectively) were found.

Conclusions
The reporting of elevated levels of depression, anxiety and stress in a subset of women more than 6 months following an ACS event underscores the importance of ongoing screening for risk factors impacting on psychological well-being and the inclusion of this information in education and counseling strategies in both the inpatient and outpatient settings. Based on these pilot data, consideration of a screening system in the immediate post discharge period for women at risk and an education or support service are recommended.

Improving access to evidence-based acute stroke services: development and evaluation of a health systems model to address equity of access issues

Level 1 evidence for management of patients with stroke in a dedicated Stroke Care Unit (SCU) demonstrates improved outcomes by about 20%. It has been estimated that 21% of Australian hospitals provide an SCU and that these SCUs are mainly located in either metropolitan sites and/or in hospitals with more than 300 beds. To address equity issues related to access to SCUs, the National Stroke Foundation and the Australian Government undertook the National Stroke Units Program. One program outcome was the development of a conceptual model of acute stroke service delivery. The development process and initial evaluation of the model are described. Use of the model to increase capacity within the health care system to treat stroke is discussed.

A randomized trial of protocol-directed sedation management for mechanical ventilation in an Australian intensive care unit

Objective: To compare protocol-directed sedation management with traditional non-protocol-directed practice in mechanically ventilated patients. Design: Randomized, controlled trial. Setting: General intensive care unit (24 beds) in an Australian metropolitan teaching hospital. Patients: Adult, mechanically ventilated patients (n = 312). Interventions: Patients were randomly assigned to receive sedation directed by formal guidelines (protocol group, n = 153) or usual local clinical practice (control, n = 159). Measurements and Main Results: The median (95% confidence interval) duration of ventilation was 79 hrs (56-93 hrs) for patients in the protocol group compared with 58 hrs (44-78 hrs) for patients who received control care (p = .20). Lengths of stay (median [range]) in the intensive care unit (94 [2-1106] hrs vs. 88 (14-962) hrs, p = .58) and hospital (13 [1-113] days vs. 13 (1-365) days, p = .97) were similar, as were the proportions of subjects receiving a tracheostomy (17% vs. 15%, p = .64) or undergoing unplanned self-extubation (1.3% vs. 0.6%, p = .61). Death in the intensive care unit occurred in 32 (21%) patients in the protocol group and 32 (20%) control subjects (p = .89), with a similar overall proportion of deaths in hospital (25% vs. 22%, p = .51). A Cox proportional hazards model, after adjustment for age, gender, Acute Physiology and Chronic Health Evaluation II score, diagnostic category, and doses of commonly used drugs, estimated that protocol sedation management was associated with a 22% decrease (95% confidence interval 40% decrease to 2% increase, p = .07) in the occurrence of successful weaning from mechanical ventilation. Conclusions: This randomized trial provided no evidence of a substantial reduction in the duration of mechanical ventilation or length of stay, in either the intensive care unit or the hospital, with the use of protocol-directed sedation compared with usual local management. Qualified high-intensity nurse staffing and routine Australian intensive care unit nursing responsibility for many aspects of ventilatory practice may explain the contrast between these findings and some recent North American studies.

The effects of a simplified tai-chi exercise program (STEP) on the physical health of older adults living in long-term care facilities : a single group design with multiple time points

Background
Studies support the positive effects that Tai Chi has on the physical health of older adults. However, many older adults residing in long-term care facilities feel too weak to practice traditional Tai Chi, and a more simplified style is preferred.
Objective
To test the effects of a newly-developed, Simplified Tai-Chi Exercise Program (STEP) on the physical health of older adults who resided in long-term care facilities.
Design
A single group design with multiple time points: three pre-tests, one month apart; four post-tests at one month, two months, three months, and six months after intervention started.
Settings
Two 300–400 bed veteran homes in Taiwan.
Participants
The 51 male older adults were recruited through convenience sampling, and 41 of them completed six-month study. Inclusion criteria included: (1) aged 65 and over; (2) no previous training in Tai Chi; (3) cognitively alert and had a score of at least eight on the Short Portable Mental Status Questionnaire; (4) able to walk without assistance; and (5) had a Barthel Index score of 61 or higher. Participants who had dementia, were wheel-chair bound, or had severe or acute cardiovascular, musculoskeletal, or pulmonary illnesses were excluded.
Methods
The STEP was implemented three times a week, 50 min per session for six months. The outcome measures included cardio-respiratory function, blood pressure, balance, hand-grip strength, lower body flexibility, and physical health actualization.
Results
A drop in systolic blood pressure (p=.017) and diastolic blood pressure (p<.001) was detected six months after intervention started. Increase in hand-grip strength from pre to post intervention was found (left hand: p<.001; right hand: p=.035). Participants also had better lower body flexibility after practicing STEP (p=.038).
Conclusions
Findings suggest that the STEP be incorporated as a floor activity in long-term care facilities to promote physical health of older adults.

Patient outcomes in the acute revovery phase following robotic-assisted prostate surgery : a prospective study

Background: Robotic-assisted minimally invasive urologic surgery was developed to minimise surgical trauma resulting in quicker recovery. It has many potential benefits for patients with localised prostate cancer over traditional surgical techniques without taking a risk with the oncological result.

Objectives: To report the specific surgical outcomes for the first Australian cohort of patients with localised prostate cancer that had undergone robotic-assisted radical prostatectomy (RARP) surgery. The outcomes represent the acute (in-hospital) recovery phase and include pain, length of stay (LOS), urinary catheter management and wound management.

Methods: Prospective descriptive survey of 214 consecutive patients admitted to a large metropolitan private hospital in Melbourne, Australia between December 2003 and June 2005. Patients had undergone RARP surgery for localised prostate cancer. Data were collected from the medical records and through interview at the time of discharge. Descriptive statistics were used to describe the frequency and proportion of outcomes. Patient characteristics were tabulated using cross tabulation frequency distribution and measures of central tendency.

Results: The findings from this study are highly encouraging when compared to outcomes associated with traditional surgical techniques. Transurethral catheter duration (median 7 days (IQ range 2)) and LOS (median 3 days (IQ range 2)) were considerably reduced. While operation time (median 3.30 h (IQ range 1.07)) was marginally reduced we would expect a further reduction as the surgical team becomes more skilled.

Conclusion: The findings from this study contribute to building a comprehensive picture of patient outcomes in the acute (in-hospital) recovery phase for a cohort of Australian patients who have undergone RARP surgery for localised prostate cancer. As such, these findings will provide valuable information with which to plan care for patients’ who undergo robotic-assisted surgery.

Readmission to an acute psychiatric unit within 28 days of discharge : identifying those at risk

Objective. To examine factors that could help identify those most at risk of readmission to an acute psychiatric in-patient unit within 28 days of a discharge.

Method. A detailed file audit was conducted comparing 54 consecutive patients who had been readmitted within 28 days of discharge with 61 patients, chosen at random, who had not been readmitted during the same period.

Results. Readmission within 28-days of discharge was associated with having been admitted in the previous year (P = 0.004), receiving the Disability Support Pension (P = 0.015), not having a discharge plan sent to the patient’s GP on discharge from the index admission (P = 0.05), receiving follow-up by the mental health team within 7 days of discharge (P = 0.007) and being unemployed (P = 0.015).

Conclusions. Targeting those with previous admissions for focussed discharge planning may help organisations reduce the numbers of unnecessary early readmissions.

What is known about the topic? Readmission within 28-days of discharge is being increasingly used by service funders and organisations as an indicator of the effectiveness of community care and of the organisation’s ability to provide continuous care across programs. Previous studies, mainly conducted in the US in the mid-90s, often reach contradictory conclusions and their relevance to the Australian setting is limited.

What does this paper add? This paper uses data from an Australia mental health service. It identifies patient and service characteristics associated with rapid re-admission and provides a baseline to evaluate strategies to reduce the readmission rate.

What are the implications for practitioners? This paper highlights the importance of careful discharge planning and communication with general practitioners particularly in relation to patients who have had previous admissions.

A descriptive interview with 64 patients discharged from an acute-psyciatric-inpatient service

Background Acute-mental-health services receive hundreds of admissions every year. Some of these patients will continue to be case-managed by community mental-health teams on discharge from the acute unit while others will not remain in contact with the mental-health service. This study compares the findings of comprehensive interviews conducted with current and past patients of the community mental-health service 3 or more years following case closure from the community ambulatory service.
Methods Between 1 July 1999 and 30 June 2001, there were 2245 closed cases identified at Barwon Health. Letters of invitation to participate in a research project were sent to people who had suffered from psychotic illnesses, and had been case-closed by community mental-health services between the above dates and had not been in contact with the Community and Mental Health Service for at least 6 months. A second group of participants was recruited from people who had also been case-closed by community mental health teams in Barwon Health during the 1999–2001 2-year-time window but whose cases had been re-opened and who were in case management with Barwon Health at the time of the study. All participants were interviewed using the Diagnostic Interview for Psychosis.
Results Letter responses were received from 17 men and 18 women, aged 40.7 ± 12.0 (mean ± SD), who were interviewed. A second group of 17 men and 12 women, aged 40.9 ± 9.6 (mean ± SD) of currently case-managed patients was interviewed. All interviewees reported a detailed history of mental illness. Persistent social dysfunction and impaired quality of life were reported in both groups.
Conclusion Patients suffering from psychotic disorders who had been case-closed by community mental-health teams and had been discharged to the care of their general practitioners or elsewhere continued to show evidence of significant impairment due to mental illness 3 years after being case-closed.

The 6-PACK programme to decrease fall-related injuries in acute hospitals: protocol for a cluster randomised controlled trial

Background and aims In-hospital fall-related injuries are a source of personal harm, preventable hospitalisation costs, and access block through increased length of stay. Despite increased fall prevention awareness and activity over the last decade, rates of reported fall-related fractures in hospitals appear not to have decreased. This cluster randomised controlled trial (RCT) aims to determine the efficacy of the 6-PACK programme for preventing fall-related injuries, and its generalisability to other acute hospitals.

Methods 24 acute medical and surgical wards from six to eight hospitals throughout Australia will be recruited for the study. Wards will be matched by type and fall-related injury rates, then randomly allocated to the 6-PACK intervention (12 wards) or usual care control group (12 wards). The 6-PACK programme includes a nine-item fall risk assessment and six nursing interventions: ‘falls alert’ sign; supervision of patients in the bathroom; ensuring patient’s walking aids are within reach; establishment of a toileting regime; use of a low-low bed; and use of bed/chair alarm. Intervention wards will be supported by a structured implementation strategy. The primary outcomes are fall and fall-related injury rates 12 months following 6-PACK implementation.

Discussion This study will involve approximately 16 000 patients, and as such is planned to be the largest hospital fall prevention RCT to be undertaken and the first to be powered for the important outcome of fall-related injuries. If effective, there is potential to implement the programme widely as part of daily patient care in acute hospital wards where fall-related injuries are a problem.
