Describing the development and implementation of a novel collaborative multidisciplinary approach to deliver foot health supports for individuals experiencing homelessness and its outcomes.

Basic foot care is a real need of people experiencing homelessness. To improve access to foot health for this group, three services structured to provide healthcare support for people experiencing homelessness collaborated in metropolitan Melbourne, Australia: an established nurse-led Homeless Persons Program (HPP), a specialty community health podiatry clinic servicing people experiencing homelessness, and a charity supporting disadvantaged communities providing free socks, foot first aid kits and second-hand footwear for distribution by nurses and podiatrists of participating services. This paper outlines the implementation and evaluation of this collaboration. A four stage implementation approach was used, addressing: 1. Who needs to do what differently? 2. What are the barriers and enablers that need to be addressed? 3. Which intervention components could overcome the modifiable barriers and enhance the enablers? 4. How can the changes be measured? The evaluation prospectively collected information about how HPP nurses referred adults to podiatry, and whether the referred individuals accessed the podiatry clinic, the outcomes of the podiatry visit, and how many received footwear, socks and foot first aid kits provided by the non-profit organisation. Over 1st June 2019 and 31st December 2020, 52 individuals were identified as adults who could potentially benefit from podiatry by the HPP nurses, of which 33 accessed podiatry. Those who did not visit the podiatry clinic were more likely to be born outside of Australia, live in more precarious housing (crisis accommodation and rough sleeping), have slightly more predisposing factors for homelessness, but have fewer medical, psychological and cognitive conditions. A structured approach including processes, education, regular, outreach to youth refuges and formal outcome monitoring enabled foot health care access in people experiencing homelessness. Further research is needed to ascertain how to support participants at risk of foot problems to access podiatry before their foot health issue reaches crisis point.

Application of StyleGAN Architecture for Generating Venous Leg Ulcer Images.

Leg ulcers caused by impaired venous blood return are the most typical chronic wound form and have a significant negative impact on the lives of people living with these wounds. Thus, it is important to provide early assessment and appropriate treatment of the wounds to promote their healing in the normal trajectory. Gathering quality wound data is an important component of good clinical care, enabling monitoring of healing progress. This data can also be useful to train machine learning algorithms with a view to predicting healing. Unfortunately, a high volume of good-quality data is needed to create datasets of suitable volume from people with wounds. In order to improve the process of gathering venous leg ulcer (VLU) data we propose the generative adversarial network based on StyleGAN architecture to synthesize new images from original samples. We utilized a dataset that was manually collected as part of a longitudinal observational study of VLUs and successfully synthesized new samples. These synthesized samples were validated by two clinicians. In future work, we plan to further process these new samples to train a fully automated neural network for ulcer segmentation.

Overground gait adaptability in older adults with type 2 diabetes in response to virtual targets and physical obstacles.

BACKGROUND: To step over an unexpected obstacle, individuals adapt gait; they adjust step length in the anterior-posterior direction prior to the obstacle and minimum toe clearance height in the vertical direction during obstacle avoidance. Inability to adapt gait may lead to falls in older adults with diabetes as the results of the effects of diabetes on the sensory-motor control system. Therefore, this study aimed to investigate gait adaptability in older adults with diabetes. RESEARCH QUESTION: Would diabetes impair gait adaptability and increase sagittal foot adjustment errors? METHODS: Three cohorts of 16 people were recruited: young adults (Group I), healthy older adults (Group II), and older adults with diabetes (Group III). Participants walked in baseline at their comfortable speeds. They then walked and responded to what was presented in gait adaptability tests, which included 40 trials with four random conditions: step shortening, step lengthening, obstacle avoiding, and walking through. Virtual step length targets were 40% of the baseline step length longer or shorter than the mean baseline step length; the actual obstacle was a 5-cm height across the walkway. A Vicon three-dimensional motion capture system and four A.M.T.I force plates were used to quantify spatiotemporal parameters of a gait cycle and sagittal foot adjustment errors (differences between desired and actual responses). Analyses of variance (ANOVA) repeated measured tests were used to investigate group and condition effects on dependent gait parameters at a significance level of 0.05. RESULTS: Statistical analyses of Group I (n = 16), Group II (n = 14) and Group III (n = 13) revealed that gait parameters did not differ between groups in baseline. However, they were significantly different in adaptability tests. Group III significantly increased their stance and double support times in adaptability tests, but these adaptations did not reduce their sagittal foot adjustment errors. They had the greatest step length errors and lowest toe-obstacle clearance, which could cause them to touch the obstacle more. SIGNIFICANCE: The presented gait adaptability tests may serve as entry tests for falls prevention programs.

Effects of diabetes mellitus on step length and minimum toe clearance adaptation.

BACKGROUND: Adaptive gait involves the ability to adjust the leading foot in response to the requirement of dynamic environments during walking. Accurate adjustments of the minimum toe clearance (MTC) height and step length can prevent older people from falling when walking and responding to hazards. Although older people with diabetes fall more frequently than healthy older adults, no previous studies have quantified their adaptive gait abilities. This study aimed to investigate the effects of diabetes mellitus on step length and MTC height adjustments using a non-immersive virtual-reality system. METHODS: Sixteen young adults (26 ± 5 years, 7 females), 16 healthy older adults (68 ± 5 years, 6 females), and 16 older adults with diabetes (70 ± 5 years, 6 females) completed adaptability tests while walking on a treadmill. A computer system visualised a continuous real-time signal of absolute step length and MTC on a monitor. Each person responded to four discrete participant-specific step length and MTC visual targets that were presented on the same signal. Tasks were to match the peaks of interest on each signal to presented targets. Targets were 10% longer or shorter than the mean baseline step length, and 2.5 cm, and 3.5 cm higher than the mean baseline MTC. When a target was displayed, it remained unchanged for 10 consecutive foot displacement adaptation attempts. Then, the target was removed and a new target or the same target was present after 10 consecutive steps and remained for 10 steps. Each target was randomly presented three times (3 × 10). Step length and MTC height adjustments in response to targets were measured and compared among groups. RESULTS: Mean preferred walking speeds were not different among groups significantly when no targets were presented on the monitor in baseline walking. However, when participants walked on a treadmill while attempting to match step lengths or MTC heights to displayed targets on the monitor, the group with diabetes had reduced step length and MTC adjustments compared with other groups significantly. They showed greater errors (differences between their step lengths/MTC heights and presented targets) on the monitor. CONCLUSIONS: This study quantified reduced abilities for older individuals with diabetes to adjust both step length and MTC in response to stimuli compared to healthy older counterparts. Reduced step length and MTC height adjustments can increase falls in at risk populations. The presented virtual-reality system has merits for assessing and training step and MTC adaptation.

Can Thermal Imaging Technique be Used to Predict the Healing Status of a Venous Leg Ulcer?

Venous leg ulcers (VLUs) are the most common chronic wound types in older populations, with many wounds not healing in the normal trajectory. Many older people with wounds are treated in their homes, currently assessed by monitoring the wound area over weeks to ascertain the potential for healing. A noncontact method using thermal imaging has been shown to predict the healing trajectory of diabetes-related foot ulcers, although has not been tested in VLU or the home setting. This project investigated the effectiveness of using thermal imaging to predict VLU healing in the homes of participants. Images of 78 ulcers were collected weekly using a thermal camera from 67 participants in their homes, at 5 consecutive time points. Final follow-up calls were undertaken at 12 weeks to ascertain healing status (healed/unhealed). Images were preprocessed and segmented and the area of the region of the wound was extracted. Kruskal-Wallis tests were performed to test the association of the change of areas over the 5 consecutive weeks with the healing status of the ulcers at 12 weeks. The 95% confidence interval plots were obtained to study the distribution of the area in the healed and unhealed cases. This study found that the difference in the imaged areas between unhealed ulcers at 12 weeks did not reach statistical significance using thermal imaging. Therefore, thermal images could not predict healing progression in VLUs when the images were taken in the homes of participants. Future research to improve the prediction of venous leg ulcer healing should include developing a protocol to standardize conditions, improve imaging process methods, and use machine learning.

Quality of life of older Australians receiving home nursing services for complex care needs.

Older Australians may live up to 10 years in ill health, most likely chronic disease-related. Those with multimorbidity report more healthcare visits, poorer health and take more medications compared with people with a single chronic disease. They are also at higher risk of hospital admission and poor quality of life. People living with multimorbidity are considered to have "complex care" needs. A person-centred approach to healthcare has led to increasing use of in-home nursing support, enabling older people to receive care at home. Our prospective observational study describes the profile and management of home-based care for older people with complex care needs and examines changes in their quality of life over 12 months. Routinely collected data were analysed, including demographics, medical history, medications and the visit activity of staff providing care to participants. Additional health-related quality of life and hospitalisation data were collected via quarterly surveys and analysed. Fifty-two participants (mean age 76.6 years, 54% female) with an average of eight diagnosed health conditions, received an average of four home care visits per week. Almost half the participants were hospitalised once during the 12-month period and experienced a significant decline in overall quality of life and in the dimensions measuring independent living and relationships over the study period. If ageing in place with good quality of life is to be realised by older adults with multimorbidity, support services including home nursing need to consider both the biomedical and social determinants perspectives when addressing health and social care needs.

Computerised prediction of healing for venous leg ulcers.

Early prediction of delayed healing for venous leg ulcers could improve management outcomes by enabling earlier initiation of adjuvant therapies. In this paper, we propose a framework for computerised prediction of healing for venous leg ulcers assessed in home settings using thermal images of the 0 week. Wound data of 56 older participants over 12 weeks were used for the study. Thermal images of the wounds were collected in their homes and labelled as healed or unhealed at the 12th week follow up. Textural information of the thermal images at week 0 was extracted. Thermal images of unhealed wounds had a higher variation of grey tones distribution. We demonstrated that the first three principal components of the textural features from one timepoint can be used as an input to a Bayesian neural network to discriminate between healed and unhealed wounds. Using the optimal Bayesian neural network, the classification results showed 78.57% sensitivity and 60.00% specificity. This non-contact method, incorporating machine learning, can provide a computerised prediction of this delay in the first assessment (week 0) in participants' homes compared to the current method that is able to do this in 3rd week and requires contact digital planimetry.

Assessing Older Community Members Using a Social Work Tool: Developing an Organizational Response.

Social Worker's undertake psycho-social assessments and facilitate access to evidence-informed psychological and practical supports to optimize the physical, psychological, and social wellbeing of the community members in their care. Social workers employed at an aged and community care organization undertook a review of the gray and peer reviewed literature and did not identify any existing evidence-based tools. However, 10 key domains were identified from the search. Gaps in the domains were discovered, together with the need for guidance and prompts for less experienced staff and students. Five Social Workers, using co-design principles, reviewed the domains, and added further domains from their social work practice. An evidence-based assessment tool was developed which incorporated 11 domains. The tool can be used to assess the needs of people living in the community who are older and/or have compromised health and wellbeing. Further work is required to pilot test the tool.

Volunteer peer support frameworks supporting older women living alone.

Volunteer peer support is an approach that enables a supportive connection between volunteers and a sub-set of community members with shared experiences or interests. To implement co-designed strategies to support older women to maintain independence and optimise wellbeing in Australia, a volunteer peer support approach was proposed. There was limited literature describing volunteer peer support frameworks to underpin interventions of this kind; and given the increasing desire for engagement of individuals and communities, articulation of the key components of such a framework is warranted. In this paper, we define volunteers and peer support, and outline existing frameworks for volunteering and peer support. We then describe the volunteer peer support framework developed for this intervention, outlining the key requirements. This information will enable others to develop an effective and sustainable structure for peer support volunteer services.

A codesigned fit-for-purpose implementation framework for aged care.

RATIONALE, AIMS AND OBJECTIVES: The field of implementation science is critical for embedding research evidence into healthcare practice, benefiting individuals, organizations, governments, and the broader community. Implementation science is messy and complex, underpinned by many theories and frameworks. Efficacious interventions for older people with multiple comorbidities exist, yet many lack effectiveness evaluation relevant to pragmatic implementation within aged care practice. This article outlines the conceptualization and development of an Implementation Framework for Aged Care (IFAC), fit-for-purpose for an aged care organization, Bolton Clarke, intent on embedding evidence into practice. METHOD: A four-stage process was adopted to (1) explore context and relevant literature to conceptualize the IFAC; (2) identify key elements for a draft IFAC; (3) expand elements and refine the draft in consultation with experts and (4) apply the IFAC to three existing projects, identifying key learnings. A checklist to operationalize the IFAC was then developed. RESULTS: The IFAC is grounded in codesign principles and encapsulated by the implementation context, from a social, cultural and political perspective. The IFAC addresses the questions of (1) why do we need to change?; (2) what do we know?; (3) who will benefit?; (4) who will make the change?; (5) what strategies will be used?; and (6) what difference are we making? Three pilot projects: early adoption of a Wellness and Reablement approach; a care worker and virtual physiotherapist-led program to prevent falls; and a therapeutic horticulture program for residential communities, highlight learnings of applying the IFAC in practice. CONCLUSION: This fit-for-purpose IFAC was developed for a proactive and responsive aged care provider. The simplicity of the six-question IFAC is underpinned by substantial theoretical perspectives for its elements and their connections. This complexity is then consolidated into an 18-question checklist to operationalize the IFAC, necessary to advance the translation of evidence into clinical practice.

Older People With Type 2 Diabetes-Individualising Management With a Specialised Community Team (OPTIMISE): Perspectives of Participants on Care.

Despite the high prevalence of diabetes in older people, there is limited information on optimal methods to support their diabetes management, including how to incorporate technology. This article reports on the results of semi-structured interviews with 41 adult participants with type 2 diabetes (mean age 74 ± 7 years) on their perspectives of a new model of care (the Older People With Type 2 Diabetes-Individualising Management With a Specialised Community Team [OPTIMISE] program) for older people with type 2 diabetes. The OPTIMISE program involved telemedicine consultations, home visits by a credentialed diabetes educator, and intermittent flash glucose monitoring. Human connection and relationships were key to the positive perspectives expressed by participants in this program that used technology to enhance the care of older people in their homes.

Thermal imaging potential and limitations to predict healing of venous leg ulcers.

Area analysis of thermal images can detect delayed healing in diabetes foot ulcers, but not venous leg ulcers (VLU) assessed in the home environment. This study proposes using textural analysis of thermal images to predict the healing trajectory of venous leg ulcers assessed in home settings. Participants with VLU were followed over twelve weeks. Digital images, thermal images and planimetry of wound tracings of the ulcers of 60 older participants was recorded in their homes by nurses. Participants were labelled as healed or unhealed based on status of the wound at the 12th week follow up. The weekly change in textural features was computed and the first two principal components were obtained. 60 participants (aged 80.53 ± 11.94 years) with 72 wounds (mean area 21.32 ± 51.28cm2) were included in the study. The first PCA of the change in textural features in week 2 with respect to week 0 were statistically significant for differentiating between healed and unhealed cases. Textural analysis of thermal images is an effective method to predict in week 2 which venous leg ulcers will not heal by week 12 among older people whose wounds are being managed in their homes.

Loneliness in older age: What is it, why is it happening and what should we do about it in Australia?

Loneliness is an important health issue facing older people due to its association with poor quality of life and poor health outcomes. This paper aimed to clarify key issues around loneliness among older adults and draw attention to innovative programs and the translation of emerging research into practice. Loneliness is a mismatch between a person's actual and desired social connections, experienced as negative emotions. Older adults are vulnerable to loneliness because of changes associated with ageing. As such, identifying as older is often seen as a burden, negatively impacting self-esteem, sense of purpose and relevance, culminating in loneliness. Interventions combatting loneliness can target individuals, relationships, communities or societies. We advocate for an intersectoral approach to support healthy ageing and reduce loneliness. This will require further research to evaluate new approaches with loneliness as the primary outcome, and additional funding to translate evidence into an integrated multi-level approach to addressing loneliness.

Age effects on step adaptation during treadmill walking with continuous step length biofeedback.

BACKGROUND: The inability to adjust step length can lead to falls in older people when navigating everyday terrain. Precisely targeted forward placement of the leading foot, constituting step length adjustment, is required for adaptive gait control, but this ability may reduce with ageing. The objective of this study was to investigate ageing effects on step length adaptation using real-time biofeedback. RESEARCH QUESTION: Does ageing affect the ability to adapt step length to match a target using real-time biofeedback? METHODS: Fifteen older adults (67 ± 3 years; 8 females) and 27 young adults (24 ± 4 years; 13 females) completed a step length adaptation test while walking at preferred speed on a treadmill. The test involved walking while viewing a monitor at the front of the treadmill that showed a real-time signal of absolute left-right foot displacement. The task was to match the local maxima of the signal (i.e. step length) to two target conditions, at 10 % longer or 10 % shorter than mean baseline step length. When the target was displayed, it remained unchanged for a set of 10 consecutive step attempts. Three sets of 10 attempts for each target condition were allocated in random order, for a total of 30 step attempts per target. Average absolute error and average error (bias) of step length accuracy was computed for each target condition and compared between groups. RESULTS: The step adaptation test identified that older adults had greater mean absolute error for both short and long step targets and showed a step length-dependent bias significantly different to the young. SIGNIFICANCE: Real-time foot position feedback could be a useful tool to train and evaluate step adaptation in older people.

Diversity training evaluation for community aged care: Tool development.

Diversity characteristics such as culture, sexual orientation, and social situation potentially impact the participation of older individuals in healthcare. An awareness of diversity characteristics and their potential to impact on older people's access to health and aged care by professionals through training is important. This paper outlines the development and initial validation of a survey using adapted Delphi methodology and distribution to 195 health and aged care professionals pre- and post-diversity training. An initial pool of 31 items were developed with an expert reference group and reduced to 21 through exploratory factor analysis. A two-factor solution was extracted, measuring skills and attitudes of professionals relative to providing services to older people with diverse characteristics. Internal consistency of the items yielded a Cronbach alpha of 0.78. T-tests conducted on the pre- and post-survey data showed significantly higher scores on the domains of skills and attitudes following the training. Knowledge was not effectively captured using this method, with true-false or free-recall questions being a more appropriate approach. This tool fills a gap in the evaluation literature, providing an important first step to assess outcomes of diversity training in community aged care. Further validation is necessary for the tool to be used more widely in the sector.

The inter-relationship of diversity principles for the enhanced participation of older people in their care: a qualitative study.

BACKGROUND: The health and aged care workforce must understand and support the diverse needs of older people to enhance their care experience. We previously identified five principles of diversity training for this workforce: awareness of unconscious bias and prejudice; promotion of inclusion; access and equity; appropriate engagement; and intersectionality. This study aims to explore how these principles are considered from the perspectives of older Australians. METHODS: Older people (≥65 years) receiving home care and nursing services based in Victoria, Australia were invited to participate in a home-based semi-structured interview about their experience of, or with, diversity. Interviews were thematically analysed using a priori categories based on our previous work on principles of diversity training, and themes were interpreted and expanded upon based on the participants' experiences and understanding of diversity concepts and their care needs. RESULTS: Fifteen older people (seven female, eight male), mean age 76 years (range 71-85 years), were interviewed. Five themes were drawn from the data. It was found that human connection through building (1) trust and rapport was highly valued as an approach by older people, crucial as a first step to understanding what is important to the older person. Identifying with (2) intersectionality, that is, the different intersecting aspects of who they are and their experiences was understood by the participants as an important framework to meet their needs. The participants were aware of (3) unconscious bias and prejudice by health professionals and its impact on their care. Participants also noted that (4) promotion of inclusion through language was important to for a positive relationship with the healthcare worker. The participants understood that to facilitate human connection, these four principles of human interaction were critical, underpinned by (5) access and equity of the system. A model articulating these relationships was developed. CONCLUSION: Health and aged care training should incorporate the five diversity principles to support older people to participate in their own care.

Community-Dwelling Older Women: The Association Between Living Alone and Use of a Home Nursing Service.

OBJECTIVE: To investigate the use of home nursing by community-dwelling older women to determine the nature of services required by those living alone. DESIGN: A retrospective cohort study using routinely collected data. SETTING AND PARTICIPANTS: Women aged 55 years and older living in metropolitan Melbourne who received an episode of nursing care from a large community home-based nursing service provider between January 1, 2006 and December 31, 2015. METHODS: Descriptive and inferential statistical analyses were used to examine the relationship between client- and service-related factors and use of community nursing services. The primary outcome of interest was the hours of service received in a care episode. RESULTS: A total of 134,396 episodes of care were analyzed, in which 51,606 (38.4%) episodes involved a woman who lived alone. The median hours of care per episode to women who lived alone was almost 70% more than that for women who lived with others. Multivariable regression identified factors influencing the amount of service use: living alone status, cognitive health status, and number of required home nursing activities. After adjusting for confounding and interactions, living alone was associated with at least 13% more hours of care than is provided to those not living alone. Compared with women who lived with others, women living alone required almost double the amount of assistance with medication management and were 30% more likely to experience a deterioration in their condition or be discharged from home nursing care into an acute hospital. From 2006 to 2015, for all women there was a trend toward fewer hours of nursing service provided per episode. CONCLUSIONS AND IMPLICATIONS: Community-dwelling older women who live alone have greater service needs and higher rates of discharge to hospital. This knowledge will help guide provision of services and strategies to prevent clinical deterioration for this population.

Co-creation of services to maintain independence and optimise well-being: Learnings from Australia's Older Women Living Alone (OWLA) project.

For many populations at risk of social isolation, including Older Women Living Alone (OWLA), existing services to maintain independence and optimise well-being are difficult to access, unsuitable or unavailable. Co-creation is a strategy to develop 'person-centred' services that meet the needs of individuals. We adapted an existing framework for co-creation and used participatory action research methods, supported by an evidence base comprising a systematic review, analysis of routinely collected data and interviews, to develop person-centred services for OWLA. This approach achieved co-creation through an iterative process of consultation and review, involving a series of facilitated discussions with women living alone and stakeholders. A total of 13 women living alone, aged ≥55 years, and 11 stakeholders representing service providers and advocacy groups, were recruited to participate in these discussions. Sessions with between three and five OWLA, were held across Melbourne. The information was compiled and presented to service stakeholders in a single facilitated forum, held in central Melbourne. Smaller facilitated sessions with OWLA followed, to review and discuss the collated service stakeholder input. The information from these OWLA sessions were again compiled and directed back to the service stakeholders for consideration and further discussion. The two groups came together for a final forum to prioritise the co-created ten services that they believed would be feasible and would address unmet need to support OWLA maintain independence. The process of co-creation was time-consuming and required considerable preparation to facilitate input from the target population. Small groups, gathering at convenient local locations, with transport support were essential in removing barriers to participation. However, co-creation was a viable method of eliciting the women's preferences and developing services more likely to meet their needs.

Trajectories of home nursing use for older women in Melbourne, Australia: 2006-2015.

OBJECTIVE: To profile changes in older women accessing home nursing between 2006 and 2015, focussing on living circumstances. METHODS: Data pertaining to Australian women aged 55+ who accessed a home nursing service between 2006 and 2015 were analysed, stratified by living status. Comparisons were made between the years 2006 and 2015; rates and relative rates of use per 1000 clients were calculated. RESULTS: Fewer women lived alone in 2015 compared with 2006. Women were older, less likely to be born in Australia, speak English at home, had more diagnoses and higher average Charlson Comorbidity Index scores in 2015. Relative rates of service use for older women living with others increased slightly over the 10 years, while decreasing by 13% for those living alone. CONCLUSION: Women using home nursing services are older than previously, more medically complex, more likely to be born from countries other than Australia and speak a preferred language other than English.

Implementation and refinement of a community health nurse model of support for people experiencing homelessness in Australia: a collaborative approach.

OBJECTIVE: To implement, refine and evaluate an assertive community health nurse (CHN) model of support for people experiencing or at risk of homelessness that aims to improve their access to health and social care services. METHODS: Participants were recruited between 30 August 2013 and 31 October 2015, including clients residing in a Victorian southern Melbourne metropolitan suburb, who registered with the CHN and stakeholders from local service provider organisations engaging with the CHN. A collaborative approach using demographic data collected from client records to identify need and measure the time clients took to engage and access services, qualitative data gathered during Stakeholder Advisory Group meetings and feedback from face-to-face interviews with service organisation representatives informed refinement of the CHN model. RESULTS: Thirty-nine clients (22 Female, mean age 50±11 years) participated. Clients engaged with services after an average of seven CHN visits. Eighteen clients independently accessed services after approximately 9 weeks, including medical and housing services. Client need and feedback from 20 stakeholders and three community nurses contributed to refining the model to ensure it met local needs and informed the necessary organisational framework, the CHN role and the attributes, knowledge and the skills required. CONCLUSION: A collaborative CHN model of support for people at risk of or experiencing homelessness has been articulated. Evaluation of the role demonstrated increased client engagement with health and community services and social activities. Additionally, the CHN assisted other service providers in their delivery of care to this very complex client group.
