The impact of a hospital-based special care unit on behavioural and psychological symptoms in older people living with dementia.

BACKGROUND: Hospital patients with behavioural and psychological symptoms of dementia (BPSD) are vulnerable to a range of adverse outcomes. Hospital-based Special Care Units (SCUs) are secure dementia-enabling environments providing specialised gerontological care. Due to a scarcity of research, their value remains unconfirmed. OBJECTIVE: To compare hospital based SCU management of BPSD with standard care. DESIGN: Single-case multiple baseline design. SETTING AND PARTICIPANTS: One-hundred admissions to an 8-bed SCU over 2 years in a large Australian public hospital. METHODS: Repeated measures of BPSD severity were undertaken prospectively by specialist dementia nurses for patients admitted to a general ward (standard care) and transferred to the SCU. Demographic and other clinical data, including diagnoses, medication use, and care-related outcomes were obtained from medical records retrospectively. Analysis used multilevel models to regress BPSD scores onto care-setting outcomes, adjusting for time and other factors. RESULTS: When receiving standard care, patients' BPSD severity was 6.8 (95% CI 6.04-7.64) points higher for aggression, 15.6 (95% CI 13.90-17.42) points higher for the neuropsychiatric inventory, and 5.8 (95% CI 5.14-6.50) points higher for non-aggressive agitation compared to SCU. Patients receiving standard care also experienced increased odds for patient-to-nurse violence (OR 2.61, 95% CI 1.67-4.09), security callouts (OR 5.39 95% CI 3.40-8.52), physical restraint (OR 17.20, 95% CI 7.94-37.25) and antipsychotic administration (OR 3.41, 95% CI 1.60-7.24). CONCLUSION: Clinically significant reductions in BPSD and psychotropic administration were associated with SCU care relative to standard ward care. These results suggest more robust investigation of hospital SCUs, and dementia-enabling design are warranted.

The Australian Delirium Clinical Care Standard: not just another brick in the wall.

Delivering delirium care is challenging. Systems may not be set up to facilitate good delirium practice and staff may have low baseline understanding of how to spot, stop and treat delirium. In this context, delirium guidelines are especially important. In this article, we review the 2021 Australian Delirium Clinical Care Standards. The care standards are different to guidelines insofar as they focus on main presentations and represent eight quality statements describing the best evidence-based care patients with delirium should be offered. The standards speak to three different audiences: consumer, clinician and healthcare organisations. As such, they provide some system-level solutions to practice-level problems. They incorporate latest evidence and reflect the sway away from prescribing to treat delirium, stating that antipsychotics should be avoided. Furthermore, they promote inclusivity of families and carers in delirium care processes as an important medium to engender good practice. Limitations include the fact that they extend to delirium in multiple settings where different approaches may be necessary. They also lack the granularity of being able to provide recommendations on a greater range of drugs that might be used and assume settings are ready to introduce best delirium practice. In sum, they represent an important step forward for delirium knowledge translation and are particularly relevant for patients in the geriatric setting. The guidelines though are constrained as to what they can advocate due to research gaps especially into treatment of delirium.

Hospital nurses' management of agitation in older cognitively impaired patients: do they recognise pain-related agitation?

BACKGROUND: cognitively impaired hospital patients often experience agitation and aggression due to pain. Agitation complicates care, increasing the risk of adverse outcomes and patient-to-nurse violence. Managing agitation is challenging for nurses. Literature suggests they may rely on antipsychotics while missing other more appropriately targeted treatments. However, nurses' management of agitation remains unclear and under-researched. OBJECTIVE: the aim of this study was to investigate hospital nurses' management of agitation in older cognitively impaired patients with pain. DESIGN: this was a descriptive correlational study using virtual simulation. SETTING AND PARTICIPANTS: a total of 274 registered medical and surgical nurses from 10 public hospitals in Queensland, Australia participated in the study. METHODS: nurses undertook a virtual simulation requiring them to manage agitation in a patient with dementia and an injury. Nurses also completed a post-simulation questionnaire. Their simulation performances were correlated with demographics such as seniority, workplace, training, experience and gerontology-specific knowledge. Constructed from an original, validated vignette, the simulation included branching pathways, video scenarios and an avatar that could converse with participants. RESULTS: thirteen nurses (4.7%) recognised and treated the virtual patient's agitation as pain-related. Most nurses (89%) gave antipsychotics of which 207 (78%) gave these first-line and 102 (38%) used them twice. Independent of other variables, nurses most likely to diagnose pain were dementia-unit nurses (OR = 8.7), surgical-unit nurses (OR = 7.3) and senior nurses (OR = 5). CONCLUSIONS: hospital nurses predominately managed agitation with antipsychotics, a decision that most made after undertaking inadequate patient assessments. This confirmed a common gap in practice that may lead to the missing of pain in the clinical care of agitated patients with dementia and/or delirium.

Qualitative analysis of challenges and enablers to providing age friendly hospital care in an Australian health system.

BACKGROUND: With ageing global populations, hospitals need to adapt to ensure high quality hospital care for older inpatients. Age friendly hospitals (AFH) aim to establish systems and evidence-based practices which support high quality care for older people, but many of these practices remain poorly implemented. This study aimed to understand barriers and enablers to implementing AFH from the perspective of key stakeholders working within an Australian academic health system. METHODS: In this interpretive phenomenenological study, open-ended interviews were conducted with experienced clinicians, managers, academics and consumer representatives who had peer-recognised interest in improving care of older people in hospital. Initial coding was guided by the Promoting Action on Research Implementation in Health Services (PARIHS) framework. Coding and charting was cross checked by three researchers, and themes validated by an expert reference group. Reporting was guided by COREQ guidelines. RESULTS: Twenty interviews were completed (8 clinicians, 7 academics, 4 clinical managers, 1 consumer representative). Key elements of AFH were that older people and their families are recognized and valued in care; skilled compassionate staff work in effective teams; and care models and environments support older people across the system. Valuing care of older people underpinned three other key enablers: empowering local leadership, investing in implementation and monitoring, and training and supporting a skilled workforce. CONCLUSIONS: Progress towards AFH will require collaborative action from health system managers, clinicians, consumer representatives, policy makers and academic organisations, and reframing the value of caring for older people in hospital.

CogChamps: impact of a project to educate nurses about delirium and improve the quality of care for hospitalized patients with cognitive impairment.

BACKGROUND: Achieving sustainable practice changes to ensure best-practice nursing care in acute hospital environments can be challenging and is not well understood. A multi-faceted practice change intervention was implemented in a large Australian hospital to enhance the capacity of the nursing workforce to provide quality care for older patients with cognitive impairment (CI). METHODS: Thirty-four experienced Registered Nurses (RNs) became Cognition Champions (CogChamps), and led practice-change initiatives to improve nursing care for older patients (≥65 years) on six wards in one hospital. The CogChamps received comprehensive education about dementia and the identification, prevention, and management of delirium. Over five months, they were supported to develop and implement ward-specific Action Plans designed to change care practices. Nurse-patient interactions were observed and patient charts were audited prior to the implementation of the plans and regularly throughout, using a purpose built Audit/ Observational tool. Data were also collected at a comparable hospital where there were no CogChamps. Data were analyzed for evidence of practice change. RESULTS: Observational and audit data were collected for 181 patients (average age = 82.5 years) across the two hospitals. All patients had CI and both cohorts had similar behavioral characteristics requiring a high level of care assistance [e.g. 38% displayed evidence of confusion/disorientation and a majority experienced meal-time difficulty (62-70%)]. While nursing practices were generally the same at both hospitals, some differences were evident (e.g. analgesia use was higher at the control hospital). Following implementation of Action Plans, significant increases in nurses' assessments of patients' cognitive functioning (35 to 69%), and administration of analgesia (27 to 48%) were observed at the intervention hospital, although only the improvement in cognitive assessments was maintained at three months follow-up. No other changes in nursing processes were evident. CONCLUSION: The CogChamps project demonstrates how RN champions were empowered to educate their colleagues about dementia and delirium resulting in a sustained increase in cognitive assessments by ward nurses. Practice improvements were mostly associated with clearly defined Action Plan tasks and goals and where responsibility for task completion was clearly assigned. These elements appear to be important when implementing practice changes. TRIAL REGISTRATION: Australian Clinical Trials Registration Number: ACTRN 12617000563369 . Retrospectively registered.

CogChamps - a model of implementing evidence-based care in hospitals: study protocol.

BACKGROUND: Delirium and dementia (cognitive impairment; CI), are common in older hospital patients, and both are associated with serious adverse outcomes. Despite delirium often being preventable, it is frequently not recognized in hospital settings, which may be because hospital nurses have not received adequate education or training in recognizing or caring for those with CI. However, the most effective way of increasing nurses' awareness about delirium and dementia, and initiating regular patient screening and monitoring to guide best practices for these patients in hospital settings is not known. Hence this current project, conducted in 2015-2017, aims to redress this situation by implementing a multi-component non-pharmacological evidence-based intervention for patients with CI, through educating and mentoring hospital nurses to change their practice. METHODS: The development of the practice change component is informed by recent findings from implementation science that focuses on facilitation as the active ingredient in knowledge uptake and utilization. This component focuses on educating and empowering experienced nurses to become Cognition Champions (CogChamps) across six wards in a large Australian tertiary referral hospital. The CogChamps will, in turn, educate other nursing team members to more effectively care for patients with CI. The hospital leadership team are supportive of the project and are directly involved in selecting the CogChamps. CogChamps will be provided with comprehensive education in evidence-based delirium assessment, prevention and management, and practice change management skills. They will receive continuing support from research and education staff about raising awareness, upskilling other staff in delirium assessment and in the adoption of best practices for preventing and managing delirium. Both qualitative and quantitative data are being collected at multiple time-points to evaluate process, impact and outcome, and to provide clarity regarding the most effective aspects of the intervention. DISCUSSION: This paper describes the study protocol for the implementation of multi-component evidence-based non-pharmacological practices designed to improve the care of older hospital patients with CI. Findings will inform subsequent initiatives directed towards enhancing the capacity of the nursing workforce to implement best practices for providing high quality care for this growing patient population throughout their acute care hospital stay.

A New Frontier: Improving Nursing Care for People With Dementia and Delirium in Hospitals.

Frederick Graham, a clinical nurse consultant from Princess Alexandra Hospital in Brisbane, Australia, presents this month's column focused on improving nursing care for people with dementia and delirium in hospitals.

Development of an education program to improve care of patients with dementia in an acute care setting.

As the population ages, the number of patients with dementia in acute care environments is projected to increase rapidly. However, many acute care nurses have undertaken little or no dementia training, potentially leading to reduced quality of care for these patients. This article details the development and delivery of a tailored education program to improve thhequality of care of patients with dementia in a large, urban hospital in Australia. Designed specifically for the existing context, environment, and knowledge levels,--the program was developed from multiple inputs including expert opinion, literature on workplace and demenitia care training, and feedback from participants. The program was delivered to acute care nurses and allied health staff within an outcome-based, microteaching model. The development and delivery tecbuniques used in this program also are discussed.

Identification and information management of cognitive impairment of patients in acute care hospitals: An integrative review.

Objectives: Recognition of the cognitive status of patients is important so that care can be tailored accordingly. The objective of this integrative review was to report on the current practices that acute care hospitals use to identify people with cognitive impairment and how information about cognition is managed within the healthcare record as well as the approaches required and recommended by policies. Methods: Following Whittemore & Knafl's five-step method, we systematically searched Medline, CINAHL, and Scopus databases and various grey literature sources. Articles relevant to the programs that have been implemented in acute care hospitals regarding the identification of cognitive impairment and management of cognition information were included. The Mixed Methods Appraisal Tool and AACODS (Authority, Accuracy, Coverage, Objectivity, Date, Significance) Checklist were used to evaluate the quality of the studies. Thematic analysis was used to present and synthesise results. This review was pre-registered on PROSPERO ( CRD42022343577). Results: Twenty-two primary studies and ten government/industry publications were included in the analysis. Findings included gaps between practice and policy. Although identification of cognitive impairment, transparency of cognition information, and interaction with patients, families, and carers (if appropriate) about this condition were highly valued at a policy level, sometimes in practice, cognitive assessments were informal, patient cognition information was not recorded, and interactions with patients, families, and carers were lacking. Discussion: By incorporating cognitive assessment, developing an integrated information management system using information technology, establishing relevant laws and regulations, providing education and training, and adopting a national approach, significant improvements can be made in the care provided to individuals with cognitive impairment.

The role of experiential knowledge in hospital nurses' management of pain-related agitation in people with dementia: An expert performance simulation study.

BACKGROUND: Pain-related agitation in hospital patients with dementia presents a diagnostic challenge as patients often cannot explain their agitation. Generally, a deductive process is required of staff, culminating in an analgesic trial. However, evidence suggests the deductions of hospital nurses may be flawed because they may not associate agitation in dementia with painful conditions, thereby missing key clinical cues. While analytical rule-based deduction applies explicit formal knowledge, cognitive scientists argue that tacit experiential knowledge, i.e., the unconscious classification of available cues, is equally important and is always involved. AIM: To identify the cognitive characteristics unique to nurses who accurately recognise pain-related agitation in a patient with dementia compared with nurses who do not. METHODS: In this descriptive multivariate study, registered acute-care nurses undertook an original computerised virtual simulation requiring them to identify and manage pain-related agitation in a standardised patient with dementia. Process tracing methods captured nurses' simulation performances alongside their retrospective accounts of thinking. These were correlated with demographic characteristics related to seniority, workplace, training, experience and knowledge captured on a questionnaire. Dual processing theory enabled interpretation of intuitive and analytical cognitive processes. FINDINGS: Registered medical and surgical nurses (N = 274) participated from 10 hospitals. Although formal knowledge about pain in dementia was high (88%), only 13(4.7%) nurses identified pain-related agitation from an injury. These individuals took the longest and used the most cues, undertaking a detailed deductive search. Their recognition of pain-related cues demonstrated accurate experiential knowledge while another 16 nurses identified a fracture without linking the injury to agitation. Over three quarters (78%) of nurses decided on initial antipsychotic treatment. They were quick to decide, using the fewest cues, suggesting agitation was recognised as typical and familiar, with the solution well-known (albeit ineffective). Independent of other variables, nurses working in dementia-specific units, surgical units or with more seniority had increased odds of recognising pain, revealing the influence of workplace experience. However, most surgical and dementia-unit nurses did not recognise pain. CONCLUSIONS: Hospital nurses have difficulty recognising when agitation in a patient with dementia is caused by pain. High formal knowledge about pain in dementia may not be sufficient to enable clinical recognition of pain in patients. Instead, nurses with experience in specific workplaces or senior roles may be better equipped to recognise pain-related agitation and deploy evidence-based approaches for agitation in a patient with dementia. Overall, these results lend support to the influence of experiential knowledge on performance. TWEETABLE ABSTRACT: In a virtual simulation, registered nurses with high formal knowledge about pain in dementia lacked the experience required to recognise pain-related agitation in a patient with dementia.

Is There a Role for Medication in Managing Delirium with Dementia?

People with dementia are more likely to develop delirium. We conducted a brief literature search and give a pragmatic overview of the key issues. Making rational and safe prescribing decisions is highly influenced by organisational culture and embedded staff practices. Comprehensive assessment for unmet physical, psychological, and social needs is an important intervention in itself. Taking a broad overview of possible pharmacological interventions should include stopping inappropriate medications and prescribing for key drivers of the underlying causes of delirium. Prescribing psychotropic medications may be indicated where there is significant distress or risk to the person with dementia and risk to those around them. It is vital to consider the dementia subtype and, where possible, involve family and friend carers in the decision-making process. Medications should be prescribed at the lowest possible dose for the least amount of time after carefully weighing risks versus benefits and documenting these. While these cases are challenging for staff and families, it can be rewarding to improve the quality of life and lessen distress for the person with dementia. There are also opportunities for informing family and friend carers, educating the wider multidisciplinary team, and promoting organisational change.

A randomized, controlled trial of the use of pulmonary-artery catheters in high-risk surgical patients.

BACKGROUND: Some observational studies suggest that the use of pulmonary-artery catheters to guide therapy is associated with increased mortality. METHODS: We performed a randomized trial comparing goal-directed therapy guided by a pulmonary-artery catheter with standard care without the use of a pulmonary-artery catheter. The subjects were high-risk patients 60 years of age or older, with American Society of Anesthesiologists (ASA) class III or IV risk, who were scheduled for urgent or elective major surgery, followed by a stay in an intensive care unit. Outcomes were adjudicated by observers who were unaware of the treatment-group assignments. The primary outcome was in-hospital mortality from any cause. RESULTS: Of 3803 eligible patients, 1994 (52.4 percent) underwent randomization. The base-line characteristics of the two treatment groups were similar. A total of 77 of 997 patients who underwent surgery without the use of a pulmonary-artery catheter (7.7 percent) died in the hospital, as compared with 78 of 997 patients in whom a pulmonary-artery catheter was used (7.8 percent)--a difference of 0.1 percentage point (95 percent confidence interval, -2.3 to 2.5). There was a higher rate of pulmonary embolism in the catheter group than in the standard-care group (8 events vs. 0 events, P=0.004). The survival rates at 6 months among patients in the standard-care and catheter groups were 88.1 and 87.4 percent, respectively (difference, -0.7 percentage point [95 percent confidence interval, -3.6 to 2.2]; negative survival differences favor standard care); at 12 months, the rates were 83.9 and 83.0 percent, respectively (difference, -0.9 percentage point [95 percent confidence interval, -4.3 to 2.4]). The median hospital stay was 10 days in each group. CONCLUSIONS: We found no benefit to therapy directed by pulmonary-artery catheter over standard care in elderly, high-risk surgical patients requiring intensive care.

Gender differences in long-term average spectra of children's singing voices.

This paper forms part of a larger study into the nature of singing development in children and examines gender differences in long-term average spectra (LTAS). Three hundred and twenty children in age groups 4-11 years learned a song and were then recorded singing alone. LTAS curves were calculated for each voice. Age of each singer was estimated and gender attributed by a panel of independent listeners. Rate of gender identification (71%) was consonant with that reported for children's speech. Progressive statistically significant shifts of spectral energy as a function of increasing age (reported in a previous study) were found to be present in the data for both genders, but the developmental timetable over which the changes took place was earlier for girls than for boys. A theoretical basis for the developmental changes is proposed.

Age-related changes in long-term average spectra of children's voices.

This paper forms part of a larger study into the nature of singing development in children. The focus here is on an investigation of age-related changes in long-term average spectra (LTAS). Three hundred and twenty children in age groups 4-11 years learned a song. Each child was then digitally recorded singing alone. LTAS curves were calculated from the recordings of each voice and perceived age was estimated by a panel of independent judges. Progressive statistically significant changes were observed in the LTAS as a function of increasing age of the children. These took the form of increases in spectral energy in all frequencies below 5.75 kHz, with concomitant reductions of energy in frequency regions above this point. Increases with age were also found in overall intensity levels of the vocal products. Four experienced listeners audited the voice samples and made estimates of the children's ages. The level of accuracy of age-estimates was remarkably high for children in the youngest age groups, but was reduced with voice samples from older children. Maturation and developing competence of the vocal system, both in growth of lung capacity and at a laryngeal level, are implicated in the generation of age-related spectral changes. Perceived child singer age appears to be less closely related to spectral characteristics (as defined within LTAS) with increasing age of children.
