RESUMO
OBJECTIVES: To compare the cost-effectiveness of coronary artery calcium (CAC) score-guided statin therapy criteria and American College of Cardiology/American Heart Association (ACC/AHA) guidelines (10-year pooled cohort equation [PCE] risk ≥ 7.5%) with selection according to Australian guidelines (5-year absolute cardiovascular disease risk [ACVDR] ≥ 10%), for people with family histories of premature coronary artery disease. STUDY DESIGN, SETTING: Markov microsimulation state transition model based on data from the Coronary Artery calcium score: Use to Guide management of Hereditary Coronary Artery Disease (CAUGHT-CAD) trial and transition probabilities derived from published statin prescribing and adherence outcomes and clinical data. PARTICIPANTS: 1083 people with family histories of premature coronary artery disease but no symptomatic cardiovascular disease. MAIN OUTCOME MEASURES: Relative cost-effectiveness over fifteen years, from the perspective of the Australian health care system, compared with usual care (Australian guidelines), assessed as incremental cost-effectiveness ratios (ICERs), with a notional willingness-to-pay threshold of $50 000 per quality-adjusted life-year (QALY) gained. RESULTS: Applying the Australian guidelines, 77 people were eligible for statin therapy (7.1%); with ACVDR 5-year risk ≥ 2% and CAC score > 0, 496 people (46%); with ACVDR 5-year risk ≥ 2% and CAC score ≥ 100, 155 people (14%); and with the ACC/AHA guidelines, 256 people (24%). The ICERs for CAC-guided selection were $33 108 (CAC ≥ 100) and $53 028 per QALY gained (CAC > 0); the ACC/AHA guidelines approach (ICER, $909 241 per QALY gained) was not cost-effective. CAC score-guided selection (CAC ≥ 100) was cost-effective for people with 5-year ACVDR of at least 5%. CONCLUSION: Expanding the number of people at low to intermediate CVD risk eligible for statin therapy should selectively target people with subclinical atherosclerosis identified by CAC screening. This approach can be more cost-effective than simply lowering treatment eligibility thresholds.

BACKGROUND: driving disruptions have significant impact on individuals living with dementia, their care partners and family members. Previous studies show that for older people with dementia, stopping driving is one of the hardest things that they cope with. To date, no studies exist that address the expressed needs and experiences of people living with young onset dementia (YOD) who are adjusting to life without driving, whose needs are not well understood and whose needs might be expected to differ from those of older people with dementia. METHODS: a multi-perspective, qualitative descriptive phenomenological approach was undertaken. A topic guide was developed in consultation with lived experience experts. In-depth interviews (n = 18) with 10 people with YOD and eight family caregivers were conducted, to elicit lived experiences in relation to changing and cessation of driving. Interviews were recorded and transcribed verbatim. Data were analysed using a hybrid approach, employing deductive and inductive coding. RESULTS: core findings reflected the impact and coping strategies employed by people with YOD and their care partners across four themes: (i) losses and burdens, (ii) the unique challenges of YOD, (iii) coping and adjustment and (iv) how to meet needs. CONCLUSIONS: driving disruptions often come at a time when people living with YOD are likely to have significant financial and family commitments, or they/their partners may be employed or raising a family, negatively impacting individual's roles and self-identities. Intervention to support emotional and practical adjustment and reduce social isolation is essential for coping.

BACKGROUND: Prognostic uncertainty and the need for proxy decision-making owing to cognitive impairment in advanced dementia, adds complexity to end-of-life care planning within the long-term care setting. Case conferences provide a structure to facilitate difficult conversations and an opportunity for family and clinicians to engage in prospective planning, and reach agreement on goals of end-of-life care. OBJECTIVE: To explore interactions between multidisciplinary healthcare clinicians and families during facilitated case conferences on end-of-life care for residents with advanced dementia. METHODS: A qualitative approach was used. Transcripts of audio-recorded case conferences facilitated by a trained registered nurse were coded by two independent researchers and analysed inductively. Transcripts were selected from an available pool until thematic saturation was reached. Emerging themes were confirmed with the wider research group. RESULTS: Thematic saturation was reached after 25 transcripts. An overarching theme concerned the ways in which clinicians and families bridged medical and person-centred perspectives. Subthemes included: details of day-to-day care versus establishing overall goals of care; expression of emotion versus retreat from emotion; and missed opportunities versus expressed cues. Successful facilitation served to 'bridge the gap' between family and clinicians. CONCLUSION: Facilitation of case conferences for residents with advanced dementia should focus on ensuring that: clinicians do not miss opportunities to discuss end-of-life care; discussions on the minutiae of care regularly return to the resident's broader goals of care; and information on dementia and treatments provided by clinicians is integrated with advice by family members regarding the resident's premorbid values and likely preferences.

AIM: To describe adults with (non-dialysis) chronic kidney disease (CKD) in nine public renal practice sites in the Australian state of Queensland. METHODS: 7,060 persons were recruited to a CKD Registry in May 2011 and until start of kidney replacement therapy (KRT), death without KRT or June 2018, for a median period of 3.4 years. RESULTS: The cohort comprised 7,060 persons, 52% males, with a median age of 68 yr; 85% had CKD stages 3A to 5, 45.4% were diabetic, 24.6% had diabetic nephropathy, and 51.7% were obese. Younger persons mostly had glomerulonephritis or genetic renal disease, while older persons mostly had diabetic nephropathy, renovascular disease and multiple diagnoses. Proportions of specific renal diagnoses varied >2-fold across sites. Over the first year, eGFR fell in 24% but was stable or improved in 76%. Over follow up, 10% started KRT, at a median age of 62 yr, most with CKD stages 4 and 5 at consent, while 18.8% died without KRT, at a median age of 80 yr. Indigenous people were younger at consent and more often had diabetes and diabetic kidney disease and had higher incidence rates of KRT. CONCLUSION: The spectrum of characteristics in CKD patients in renal practices is much broader than represented by the minority who ultimately start KRT. Variation in CKD by causes, age, site and Indigenous status, the prevalence of obesity, relative stability of kidney function in many persons over the short term, and differences between those who KRT and die without KRT are all important to explore.

Unlawful assisted dying practices have been reported in Australia for decades. Voluntary assisted dying (VAD) is now lawful in Victoria and Western Australia in limited circumstances and will soon be lawful in a further four Australian States. This article examines nine cases involving unlawful assisted dying practices in Victoria in the 12 months prior to the commencement of the Voluntary Assisted Dying Act 2017 (Vic) in 2019. It explores whether, if that Act had been in operation at the relevant time, these patients would have been eligible to request VAD, having regard to their decision-making capacity and their disease, illness or medical condition. Many of these patients would not have been eligible to request VAD had the legislation been operational, primarily because they lacked decision-making capacity. As VAD is lawful only in a narrow set of circumstances, unlawful assisted deaths may continue to occur in those States where voluntary assisted dying is legal.

The Coronavirus disease 2019 (COVID-19) emergency has demonstrated that the utilization of face masks plays a critical role in limiting the outbreak. Healthcare professionals utilize masks all day long without replacing them very frequently, thus representing a source of cross-infection for patients and themselves. Nanotechnology is a powerful tool with the capability to produce nanomaterials with unique physicochemical and antipathogen properties. Here, how to realize non-disposable and highly comfortable respirators with light-triggered self-disinfection ability by bridging bioactive nanofiber properties and stimuli-responsive nanomaterials is outlined. The visionary road highlighted in this Concept is based on the possibility of developing a new generation of masks based on multifunctional membranes where the presence of nanoclusters and plasmonic nanoparticles arranged in a hierarchical structure enables the realization of a chemically driven and on-demand antipathogen activities. Multilayer electrospun membranes have the ability to dissipate humidity present within the mask, enhancing the wearability and usability. The photothermal disinfected membrane is the core of these 3D printed and reusable masks with moisture pump capability. Personalized face masks with smart nano-assisted destruction of pathogens will bring enormous advantages to the entire global community, especially for front-line personnel, and will open up great opportunities for innovative medical applications.

OBJECTIVE: To explore the general practitioners (GP's) role in providing psychosocial care for cancer survivors through a systematic literature review. METHODS: We searched MEDLINE, EMBASE, PsycINFO, and CINAHL and included the studies that complied with the predefined inclusion and exclusion criteria. At least two independent reviewers performed the quality appraisal and data extraction. RESULTS: We included 33 (five qualitative, 19 observational, and nine intervention) studies; the majority of these studies focused on care for depression and anxiety (21/33). Cancer survivors were more likely to contact their GP for psychosocial problems compared with noncancer controls. Survivors were more likely to use antidepressants compared with controls, although 71% of survivors preferred depression treatment to be "talking therapy only." Overall, GPs and patients mostly agreed that GPs are the preferred healthcare provider to manage psychosocial problems. The major exception is a survivor's fear of recurrence-here, the oncologist was the preferred healthcare provider. Only two interventions effectively decreased depression or anxiety; these studies included patients who had a clinical indication for psychosocial care, were specifically designed for decreasing depression/anxiety, and consisted of a multidisciplinary team approach. The other interventions evaluated GP-led follow-up for cancer survivors and found that this did not impact the patients' levels of anxiety, depression, or distress neither negatively nor positively. CONCLUSIONS: Cancer survivors often prefer psychosocial care by their GP, and GPs generally consider they are well placed to provide this care. Although evidence on the effectiveness of psychosocial care by GPs is limited, an active multidisciplinary team approach seems key.

BACKGROUND: Family meetings facilitate the exploration of issues and goals of care however, there has been minimal research to determine the benefits and cost implications. AIMS: To determine: (1) if family caregivers of hospitalised patients referred to palliative care who receive a structured family meeting report lower psychological distress (primary outcome), fewer unmet needs, improved quality of life; feel more prepared for the caregiving role; and receive better quality of end-of-life care; (2) if outcomes vary dependant upon site of care and; (3) the cost-benefit of implementing meetings into routine practice. DESIGN: Pragmatic cluster randomised trial involving palliative care patients and their primary family caregivers at three Australian hospitals. Participants completed measures upon admission (Time 1); 10 days later (Time 2) and two months after the patient died (Time 3). Regression analyses, health utilisation and process evaluation were conducted. RESULTS: 297 dyads recruited; control (n = 153) and intervention (n = 144). The intervention group demonstrated significantly lower psychological distress (Diff: -1.68, p < 0.01) and higher preparedness (Diff: 3.48, p = 0.001) at Time 2. No differences were identified based on quality of end of life care or health utilisation measures. CONCLUSIONS: Family meetings may be helpful in reducing family caregiver distress and enhancing their preparedness for the caregiving role and it appears they may be conducted without increased hospital health utilisation impacts; although opportunity costs need to be considered in order to routinely offer these as a standardised intervention. Additional health economic examination is also advocated to comprehensively understand the cost-benefit implications.

BACKGROUND: Voluntary assisted dying is lawful in Victoria in limited circumstances and commences in Western Australia in mid-2021. There is evidence that in rare cases, unlawful assisted dying practices occur in Australia. AIMS: To determine whether assisted dying practices occurred in Victoria in the 12 months prior to the commencement of the Voluntary Assisted Dying Act 2017 (Vic) ('VAD Act'), and to examine features of any identified cases. METHODS: Exploratory case series of adult patients in Victoria who died between May 2018 and 18 June 2019 as a result of medication administered with the primary intention of hastening death. Cases were identified from a self-administered survey about medical end-of-life decisions for adult patients, completed by Victorian specialists treating adults at the end of life. We examined reported use of medication with the primary intention of hastening the patient's death; characteristics of assisted dying cases, including doctors' classification of such practices. RESULTS: Nine cases met the inclusion criteria. Death did not occur immediately after providing medication with the intention of hastening death. In eight cases, it was framed as palliative or terminal sedation and/or continuous deep sedation. Most doctors used language that distanced their practices from assisted dying. CONCLUSIONS: Unlawful assisted dying practices seem to have occurred in a small number of deaths in Victoria prior to commencement of the VAD Act. These practices typically occurred within the context of palliative or terminal sedation and may be difficult to distinguish from lawful palliative care practice. Some survey responses possibly reflect ambiguity in doctors' intentions when providing medication.

Antioxidant activity is an important feature for food contact materials such as packaging, aiming to preserve freshness and retard food spoilage. Common bioactive agents are highly susceptible to various forms of degradation; therefore, protection is required to maintain functionality and bioavailability. Poly(ε-caprolactone) (PCL), a biodegradable GRAS labeled polymer, was used in this study for encapsulation of α-tocopherol antioxidant, a major component of vitamin E, in the form of electrospun fibers. Rheological properties of the fiber forming solutions, which determine the electrospinning behavior, were correlated with the properties of electrospun fibers, e.g., morphology and surface properties. Interactions through hydrogen bonds were evidenced between the two components. These have strong effect on structuration of macromolecular chains, especially at low α-tocopherol amounts, decreasing viscosity and elastic modulus. Intra-molecular interactions in PCL strengthen at high α-tocopherol amounts due to decreased solvation, allowing good structural recovery after cease of mechanical stress. Morphologically homogeneous electrospun fibers were obtained, with ~6 µm average diameter. The obtained fibers were highly hydrophobic, with fast release in 95% ethanol as alternative simulant for fatty foods. This induced good in vitro antioxidant activity and significant in vivo reduction of microbial growth on cheese, as determined by respirometry. Therefore, the electrospun fibers from PCL entrapping α-tocopherol as bioactive agent showed potential use in food packaging materials.

Palliative care is the province of everyone, particularly people managing older patients. Most people die of multimorbidity, frailty and dementia rather than cancer and will never see a palliative care specialist. People dying from non-malignant disease have symptoms and problems that are usually predictable. Common symptoms like pain and dyspnoea can be anticipated. Planning to prevent them, or for when they occur, is more effective than waiting until they happen. Deprescribing is an effective way of preventing morbidity in this group. Getting to know a few medicines well for each symptom is important when providing palliative care for patients. Starting at low doses and increasing slowly is also key.
RESUMO
PURPOSE OF REVIEW: Opioids are the only class of drug with the proven ability to control severe pain. The introduction of stringent opioid prescribing restrictions has inevitably impacted upon the ability of those prescribing opioids for advanced life-limited disease to practice as previously and could limit the supply of adequate pain relief to patients with cancer. This review considers the evidence that symptom management of patients with advanced cancer contributes to the "opioid problem" and whether there is adequate recognition of the risks involved. RECENT FINDINGS: The literature suggests that the risk of opioid abuse is low in the palliative care population as is the risk of legal consequences for doctors prescribing opioids at the end of life. However, as many patients with cancer are living longer or surviving with chronic pain, palliative care physicians must be cognisant not only of the risks of long term opioid use but also of the risk of opioid misuse. Adherence to evidence or consensus-based guidelines is necessary to avoid inappropriate prescribing. In palliative care, it is appropriate not only to exercise a reasonable degree of opioid control and surveillance, primarily for the good of society, but also to ensure that the ability to treat pain in patients with advanced malignant disease is not compromised.

OBJECTIVES: To assess the predictive value of the Australian absolute cardiovascular disease risk (ACVDR) calculator and other assessment tools for identifying Australians with family histories of early onset coronary artery disease (CAD) who have coronary artery calcification. DESIGN, SETTING, PARTICIPANTS: People without known CAD were recruited at seven Australian hospitals, October 2016 - January 2019. Participants were aged 40-70 years, had a family history of early onset CAD, and a 5-year ACVDR of 2-15%. MAIN OUTCOME MEASURES: CT coronary artery calcium score greater than zero (any coronary calcification) or greater than 100 (calcification warranting lipid therapy). RESULTS: 1059 participants were recruited; 477 (45%) had non-zero coronary artery calcium scores (median 5-year ACVDR, 4.8% [IQR, 2.9-7.6%]; median coronary artery calcium score, 41.7 [IQR, 8-124]); 582 (55%) did not (median 5-year ACVDR, 3.2% [IQR, 2.0-4.6%]). Of 151 participants with calcium scores of 100 or more, 116 (77%) were deemed to be at low cardiovascular risk by Australian guidelines, while 14 of 75 participants at intermediate risk (19%) had zero calcium scores. The sensitivity of the ACVDR calculator for identifying people with non-zero calcium scores (area under receiver operator curve [AUC], 0.674) was lower than that of the pooled cohort equation (AUC, 0.711; P < 0.001). ACVDR (10-year)- and Multi-Ethnic Study of Atherosclerosis (MESA)-predicted risk categories concurred for 511 participants (48%); classifications were concordant for 925 participants (87%) when the ACVDR was supplemented by calcium scores. CONCLUSIONS: Coronary artery calcium scoring should be considered as part of the heart health check for patients at intermediate ACVDR risk and with family histories of early onset CAD. Alternative risk calculators may better select such patients for further diagnostic testing and primary prevention therapy.

BACKGROUND: Some patients do not receive adequate pain and symptom relief at the end of life, causing distress to patients, families and healthcare professionals. It is unclear whether undertreatment of symptoms occurs, in part, because of nurses' concerns about legal and/or disciplinary repercussions if the patient dies after medication is administered. AIM: The aim was to explore nurses' experiences and knowledge of the law relating to the provision of end-of-life pain and symptom relief. DESIGN: Semi-structured interviews with nurses were assessed using a six-stage hybrid thematic analysis technique. SETTING/PARTICIPANTS: Four face-to-face and 21 telephone interviews were conducted with nurses who routinely prescribed and/or administered pain and symptom relief to patients approaching the end of their lives in Queensland and New South Wales, Australia. RESULTS: While many nurses had no personal experiences with legal or professional repercussions after a patient had died, the fear of hastening death and being held accountable was frequently discussed and regarded as relevant to the provision of inadequate pain and symptom relief. Concerns included potential civil or criminal liability and losing one's job, registration or reputation. Two-thirds of participants believed that pain relief was sometimes withheld because of these legal concerns. Less than half of the interviewed nurses demonstrated knowledge of the doctrine of double effect, the legal protection for health professionals who provide end-of-life pain and symptom relief. CONCLUSION: Education is urgently required to strengthen nurses' knowledge of the legal protections supporting the provision of appropriate palliative medication, thereby improving their clinical practice with end-of-life patients.

BACKGROUND: End-of-life discussions often are not initiated until close to death, even in the presence of life-limiting illness or frailty. Previous research shows that doctors may not explicitly verbalize approaching end-of-life in the foreseeable future, despite shifting their focus to comfort care. This may limit patients' opportunity to receive information and plan for the future. General Practitioners (GPs) have a key role in caring for increasing numbers of patients approaching end-of-life. OBJECTIVE: To explore GPs' thought processes when deciding whether to initiate end-of-life discussions. METHODS: A qualitative approach was used. We purposively recruited 15 GPs or GP trainees from South-East Queensland, Australia, and each participated in a semi-structured interview. Transcripts were analyzed using inductive thematic analysis. RESULTS: Australian GPs believe they have a responsibility to initiate end-of-life conversations, and identify several triggers to do so. Some also describe caution in raising this sensitive topic, related to patient, family, cultural and personal factors. CONCLUSIONS: These findings enable the development of approaches to support GPs to initiate end-of-life discussions that are cognizant both of GPs' sense of responsibility for these discussions, and factors that may contribute to caution initiating them, such as anticipated patient response, cultural considerations, societal taboos, family dynamics and personal challenges to doctors.

BACKGROUND: As doctors who provide care across the life-course, general practitioners (GPs) play a key role in initiating timely end-of-life discussions. Nonetheless, these discussions are often not initiated until close to death. Given the ageing of the population, GPs will be confronted with end-of-life care more often, and this needs to become a core skill for all GPs. OBJECTIVE: To describe GPs' approach to initiating end-of-life discussions. METHODS: Fifteen GPs or GP trainees from South-East Queensland, Australia, were purposively recruited to participate in a semi-structured interview. We analysed transcripts using a thematic analysis. RESULTS: GPs' approach to initiating end-of-life discussions was summarized by four themes: (1) Preparing the ground; (2) finding an entry point; (3) tailoring communication and (4) involving the family. CONCLUSIONS: Emphasis on the doctor-patient relationship; assessing patient readiness for end-of-life discussions; and sensitive information delivery is consistent with factors previously reported to be important to both GPs and patients in this context. Our findings provide a framework for GPs initiating end-of-life discussions, which must be tailored to patient and GP personality factors. Further research is required to evaluate its outcomes.

Attention deficit/hyperactivity disorder (ADHD) is often accompanied by sleep problems in children. Sleep hygiene is defined as a set of behavioural, environmental, or cognitive modifications to improve sleep, and is routinely clinically utilised as first-line treatment for insomnia in ADHD. The objective of this systematic review of the literature is to evaluate the effectiveness of sleep hygiene interventions for sleep difficulties in children with ADHD. Sixteen relevant articles met the inclusion criteria, involving 1,469 participants, with a mean age of 9.6 years, across 6 countries. Fifteen studies found that sleep hygiene interventions were effective in improving sleep, while one did not show any significant improvement. Definite conclusions on the effectiveness of the interventions are difficult to draw due to the limited number of studies and a high risk of bias. There is growing evidence to support the use of sleep hygiene interventions to improve sleep quality in children with ADHD and sleep disturbance. However, well-conducted clinical trials are required to strengthen the evidence.

Sodium alginate (NaAlg) based membranes were prepared using a solution technique, crosslinked with poly(styrene sulfonic acid-co-maleic acid) (PSSA-co-MA). Subsequently, the membranes were modified by the incorporation of 0, 10, 20, 30 and 40% w/w of titanium dioxide with respect to sodium alginate. The membranes thus obtained were designated as M, M-1, M-2, M-3 and M-4, respectively. An equilibrium swelling experiment was performed using different compositions of the water and isopropanol mixtures. Subsequently, we used a pervaporation cell fitted with each membrane in order to evaluate the extent of the pervaporation dehydration of isopropanol. Among the membranes studied, the membranes containing 40 mass% of titanium dioxide exhibited the highest separation factor(α) of 24,092, with a flux(J) of 18.61 × 10-2 kg/m2âh at 30 °C for 10 mass% w/w of water in the feed. The total flux and the flux of water were found to overlap with each other, indicating that these membranes can be effectively used to break the azeotropic point of water-isopropanol mixtures. The results clearly indicate that these nanocomposite membranes exhibit an excellent performance in the dehydration of isopropanol. The activation energy values obtained for the water permeation were significantly lower than those of the isopropanol permeation, underlining that these membranes have a high separation ability for the water-isopropanol system. The estimated activation energies for total permeation (EP) and total diffusion (ED) values ranged between 10.60 kJâmol-1 and 3.96 kJâmol-1, and 10.76 kJâmol-1 and 4.29 kJâmol-1, respectively. The negative change in the enthalpy values for all the membranes indicates that sorption was mainly dominated by Langmuir's mode of sorption.

OBJECTIVE: Psychological therapies combined with medication are effective treatments for depression and anxiety in patients with cancer. However, the psycho-oncology workforce is insufficient to meet patient need and is hard to access outside of the major cities. To bridge this gap, innovative models of care are required. Implementation of a new model of care requires attention to the facilitators and barriers. The aim of this study was to explore stakeholders' attitudes to the feasibility and acceptability of a community-based, shared care model for the treatment of depression and anxiety. METHODS: Semi-structured interviews were conducted with community-based clinical psychologists (n = 10), general practitioners (n = 6), and hospital-based psychologists working in psycho-oncology (n = 9). Framework analysis was conducted to identify key themes. RESULTS: All stakeholders perceived the model as feasible and acceptable. Potential barriers/facilitators to implementation were summarised under six key themes: (a) initiative, ownership, and autonomy; (b) resources; (c) pathway establishment; (d) support; (e) skill acquisition; and (f) patient engagement. Facilitators included quality communication between health professionals across primary and tertiary care and appropriate education and support for community-based clinicians. CONCLUSIONS: This in-depth exploration of Australian health professionals' perceptions of the feasibility and acceptability of a community-based model of psycho-oncology care revealed that most clinicians were willing to adopt the proposed changes into practice. An RCT of a shared care intervention for depressed patients with cancer is needed.

BACKGROUND: Giving up driving is a pivotal life event and universal challenge for people living with dementia and their families, and a complex area of clinical practice for health professionals who monitor driving cessation. The best outcomes are for individuals to plan for and eventually cease driving, however with insufficient support programs in place, many avoid the issue until it is reaches a crisis point. This program of research investigates a comprehensive support- and education-based intervention targeted at people living with dementia and their care partners who are managing driving cessation. The primary aim of this research is to determine the effectiveness of the program through a cluster randomized controlled trial. METHODS/DESIGN: The intervention (CarFreeMe) is an intensive program delivered by a trained health professional that addresses practical and emotional needs relevant to driving cessation. The seven module program is person-centred, covering awareness raising, adjustment, and practical support that is individualized according to geographic location and the particular goals and preferences of participants. A cluster randomized controlled trial will evaluate the effectiveness of the program. Evaluation will take place pre-intervention, immediately following, and three months post-intervention. Clusters are randomized to either intervention or usual treatment. Participants within clusters will be recruited via primary and secondary care clinics, community agencies, service providers, local media, social media, support groups, and word of mouth. The primary outcome measure for persons with dementia and their care partners is lifespace, collected via (i) smartphone GPS technology and (ii) self-reported number of episodes away from home (during the past week). Secondary outcomes include safe alternative transport status, wellbeing, depression, anxiety, and self-efficacy, which will be collected from dyads. Caregiving strain will be collected from care partner/family member only. A process evaluation of the intervention will also be undertaken. DISCUSSION: There is an urgent need for therapeutic approaches to supporting people living with dementia and their families to negotiate the complex decision making involved in deciding to change their approach to driving. The driving cessation intervention may fill an important gap in service delivery to people living with dementia who are adjusting to life without driving.
