Feasibility of a physiotherapist-supervised walking program with telephone coaching to increase physical activity following acquired brain injury.

Background Physical activity has health benefits for adults with acquired brain injury, but it is a challenge to increase physical activity during inpatient rehabilitation. The objectives of this pilot study were to determine whether a physiotherapy-supervised inpatient walking program was feasible and able to improve physical activity and sedentary behaviour in the short and medium term. Methods Adults with acquired brain injury receiving inpatient rehabilitation undertook twice-weekly supervised walks plus behavioural therapy for 4 weeks. Feasibility was measured via recruitment, participation and drop out rates, adverse events and intervention delivery costs. Physical activity and sedentary behaviour were measured with an activPAL. Assessments were conducted at baseline, post-intervention and 3-6 months post-intervention. Results The program was safe to deliver (no adverse events), recruitment rate was 55% (16/29) and the participation rate for eligible individuals was high (14/19, 74%). However, the program had a high drop out rate (7/16, 44%) and physical activity and sedentary behaviour did not significantly change during the 4-week intervention. Costs were AU$427.71/participant. Physical activity and sedentary behaviour did improve 3-6 months after the intervention (vs baseline, on average: +3913 steps per day, 95% CI: 671, 7156). Conclusion This pilot study demonstrated a supervised physiotherapy walking program is safe and feasible to recruit in an inpatient setting. However, drop out during the study was high and behaviour change did not occur. More work is required to boost physical activity during sub-acute rehabilitation for acquired brain injury.

Cashing in: cost-benefit analysis framework for digital hospitals.

BACKGROUND: For many countries, especially those outside the USA without incentive payments, implementing and maintaining electronic medical records (EMR) is expensive and can be controversial given the large amounts of investment. Evaluating the value of EMR implementation is necessary to understand whether or not, such investment, especially when it comes from the public source, is an efficient allocation of healthcare resources. Nonetheless, most countries have struggled to measure the return on EMR investment due to the lack of appropriate evaluation frameworks. METHODS: This paper outlines the development of an evidence-based digital health cost-benefit analysis (eHealth-CBA) framework to calculate the total economic value of the EMR implementation over time. A net positive benefit indicates such investment represents improved efficiency, and a net negative is considered a wasteful use of public resources. RESULTS: We developed a three-stage process that takes into account the complexity of the healthcare system and its stakeholders, the investment appraisal and evaluation practice, and the existing knowledge of EMR implementation. The three stages include (1) literature review, (2) stakeholder consultation, and (3) CBA framework development. The framework maps the impacts of the EMR to the quadruple aim of healthcare and clearly creates a method for value assessment. CONCLUSIONS: The proposed framework is the first step toward developing a comprehensive evaluation framework for EMRs to inform health decision-makers about the economic value of digital investments rather than just the financial value.

Implementing good life with osteoArthritis from Denmark (GLA:D®) in Australian public hospitals. Part 2: Service providers' perceptions.

BACKGROUND: Previous literature has reported the successful implementation of the Good Life with osteoArthritis in Denmark (GLA:D®) program into predominantly private practice settings. There may be unique challenges present within the public hospital setting that influence GLA:D® implementation in public health. OBJECTIVE: Explore the attitudes and experiences of service providers directly involved in implementing GLA:D® in Australian public tertiary hospitals. DESIGN: Qualitative descriptive study design. METHOD: Service providers (n = 14) from three participating hospitals took part in semi-structured focus groups at the completion of the 6-month implementation period. Inductive thematic analysis was employed to identify primary domains across all facilities. RESULTS: Four broad domains were identified. Factors that influenced uptake included GLA:D® being a recognisable, evidence-based product requiring minimal development or adaptation. The fidelity of the GLA:D® Australia program was challenged by referral of patients with multiple/complex medical comorbidities, and patient preference to complete registry data via paper rather than online. Several operational considerations are required when delivering GLA:D® in a public hospital setting, including adequate numbers of GLA:D®-trained staff, additional screening requirements, obtaining appropriate clinical space, and persisting patient barriers to attending the service. GLA:D® provided benefits beyond improvement in pain and function, including social interactivity, high attendance and promotion of long-term self-management, while also maximising service efficiencies. CONCLUSIONS: Implementing GLA:D® in Australian public hospitals was supported by service providers. Specific operational and administrative factors, including staff training, patient complexity, and registry requirements should be considered when attempting to embed and sustain GLA:D® in large Australian public tertiary hospitals.

Implementing good life with osteoArthritis from Denmark (GLA:D®) in australian public hospitals. Part 1: Feasibility.

BACKGROUND: Literature reporting positive outcomes from the Good Life with osteoArthritis in Denmark (GLA:D®) program in Australia mainly involves patients attending private physiotherapy services. OBJECTIVE: Evaluate the feasibility of implementing GLA:D® in Australian public hospitals. DESIGN: Implementation study in three metropolitan tertiary public hospitals over six months. METHOD: Patients aged ≥18 years with knee or hip joint-related problems deemed appropriate for non-surgical care were invited to participate in GLA:D®. Feasibility was evaluated using RE-AIM framework components (Implementation, Effectiveness, Maintenance) using service-level metrics, patient-level data, and program fidelity assessment. Findings of qualitative interviews with service providers are presented in Part 2. RESULTS: Implementation: 70 patients (69 with knee osteoarthritis) participated (13 cohorts). 55 (79%) patients attended both education sessions, and 49 patients (70%) attended 10-12 exercises sessions. Fidelity was met based on environmental, therapist, participant- and program-related criteria. EFFECTIVENESS: At 3 months, patients reported lower average pain (visual analogue scale [0-100 mm]: effect size -0.56, 95% CI -0.88 to -0.23) and disability (HOOS/KOOS-12 [100-0]: 0.67, 0.28 to 1.05), and improved quality of life (EQ-5D overall score: 0.46, 0.11 to 0.80). No adverse events were reported. All patients who completed 3-month assessment (n = 52) would recommend GLA:D®. Maintenance: All participating services elected to continue delivering GLA:D® beyond the study. CONCLUSIONS: Implementing GLA:D® in Australian public hospitals is feasible, safe, and acceptable to patients with knee osteoarthritis. Public hospital patients with knee osteoarthritis reported improvements in pain, disability, and quality of life similar to previous GLA:D® cohorts.

Telehealth Cognitive Behavior Therapy to Reduce Anxiety in People Living with Cognitive Impairment: A Randomized Feasibility Pilot Study.

OBJECTIVES: To evaluate the feasibility of telehealth-based cognitive behavior therapy for people living with cognitive impairment experiencing anxiety (Tele-CBT), and to assess whether this leads to improvements in anxiety, depression, and quality of life post-intervention. METHODS: This was a single-blind randomized feasibility pilot trial of the Tele-CBT versus usual care. People living with mild cognitive impairment or dementia experiencing anxiety were recruited and randomized to receive Tele-CBT (n = 5) or continue usual care (n = 5). Feasibility data comprised recruitment uptake and retention, adherence, and ease of use. Outcomes of anxiety (primary outcome - Rating Anxiety in Dementia; RAID), depression, stress, and quality of life were measured pre- and post-intervention. RESULTS: Intervention feasibility was demonstrated through minimal attrition, acceptability, and ease of use via videoconferencing. Both groups showed a decrease of anxiety symptoms (RAID) from baseline to post-assessment. CONCLUSIONS: The Tele-CBT program was acceptable to use via videoconferencing. Reduced anxiety symptoms were observed in both groups at post-. An RCT with a larger sample is required to determine the efficacy and implementation of the intervention. CLINICAL IMPLICATIONS: This study indicates the feasibility of videoconference CBT to address anxiety experienced by people living with cognitive impairment with minimal assistance from support persons.

Validating care and treatment scenarios for measuring decisional conflict regarding future care preferences among older adults.

OBJECTIVE: Decisional conflict is used increasingly as an outcome measure in advance care planning (ACP) studies. When the Decisional Conflict Scale (DCS) is used in anticipatory decision-making contexts, the scale is typically tethered to hypothetical scenarios. This study reports preliminary validation data for hypothetical scenarios relating to life-sustaining treatments and care utilisation to inform their broader use in ACP studies. METHODS: Three hypothetical scenarios were developed by a panel of multidisciplinary researchers, clinicians and community representatives. A convenience sample of 262 older adults were surveyed. Analyses investigated comprehensibility, missing data properties, sample norms, structural, convergent and discriminant validity. RESULTS: Response characteristics suggested that two of the scenarios had adequate comprehensibility and response spread. Missing response rates were unrelated to demographic characteristics. Predicted associations between DCS scores and anxiety (r's = .31-.37, p < .001), and ACP engagement (r's = -.41 to -.37, p < .001) indicated convergent validity. CONCLUSION: A substantial proportion of older adults reported clinically significant levels of decisional conflict when responding to a range of hypothetical scenarios about care or treatment. Two scenarios showed acceptable comprehensibility and response characteristics. A third scenario may be suitable following further refinement. PATIENT OR PUBLIC CONTRIBUTION: The scenarios tested here were designed in collaboration with a community representative and were further piloted with two groups of community members with relevant lived experiences; four people with life-limiting conditions and five current or former care partners.

Reinforcing informed medication prescription for low back pain in the emergency department (RIME): a controlled interrupted time series implementation study protocol.

INTRODUCTION: Management guidelines for low back pain (LBP) recommend exclusion of serious pathology, followed by simple analgesics, superficial heat therapy, early mobilisation and patient education. An audit in a large metropolitan hospital emergency department (ED) revealed high rates of non-recommended medication prescription for LBP (65% of patients prescribed opioids, 17% prescribed benzodiazepines), high inpatient admission rates (20% of ED LBP patients), delayed patient mobilisation (on average 6 hours) and inadequate patient education (48% of patients). This study aims to improve medication prescription for LBP in this ED by implementing an intervention shown previously to improve guideline-based management of LBP in other Australian EDs. METHODS AND ANALYSIS: A controlled interrupted time series study will evaluate the intervention in the ED before (24 weeks; 20 March 2023-3 September 2023) and after (24 weeks; 27 November 2024-12 May 2024) implementation (12 weeks; 4 September 2023-26 November 2023), additionally comparing findings with another ED in the same health service. The multicomponent implementation strategy uses a formalised clinical flow chart to support clinical decision-making and aims to change clinician behaviour, through clinician education, provision of alternative treatments, educational resources, audit and feedback, supported by implementation champions. The primary outcome is the percentage of LBP patients prescribed non-recommended medications (opioids, benzodiazepines and/or gabapentinoids), assessed via routinely collected ED data. Anticipated sample size is 2000 patients (n=1000 intervention, n=1000 control) based on average monthly admissions of LBP presentations in the EDs. Secondary outcomes include inpatient admission rate, time to mobilisation, provision of patient education, imaging requests, representation to the ED within 6 months and healthcare costs. In nested qualitative research, we will study ED clinicians' perceptions of the implementation and identify how benefits can be sustained over time. ETHICS AND DISSEMINATION: This study received ethical approval from the Metro North Human Research Ethics Committee (HREC/2022/MNHA/87995). Study findings will be published in peer-reviewed journals and presented at international conferences and educational workshops. TRIAL REGISTRATION NUMBER: ACTRN12622001536752.

A post-diagnosis information and support programme for dyads-People living with dementia or mild cognitive impairment and family carers: A feasibility study.

AIM: The aim of the study was to establish the feasibility of delivering a structured post-diagnosis information and support program to dyads (persons living with dementia or mild cognitive impairment and family carers) in two primary care settings. DESIGN: A two-phase explanatory mixed-method approach guided by the Bowen Feasibility Framework focused on acceptability, implementation, adaptation, integration and efficacy of a five-part programme. In phase 1, the quantitative impact of the programme on the dyadic programme recipients' self-efficacy, quality of life, dyadic relationship and volume of care was measured. In phase 2, inductive content analysis focused on nurse and dyad participant experiences of the programme. Quantitative and qualitative data were reviewed to conclude each element of feasibility. METHODS: Four registered nurses working within the participating sites were recruited, trained as programme facilitators and supported to deliver the programme. Eligible dyads attending the respective primary health clinics were invited to participate in the programme and complete surveys at three time points: recruitment, post-programme and 3-month follow-up. Post-programme semi-structured interviews were conducted with dyads and programme facilitators. RESULTS: Twenty-nine dyads completed the program; the majority were spousal dyads. The programme proved acceptable to the dyads with high retention and completion rates. Implementation and integration of the programme into usual practice were attributed to the motivation and capacity of the nurses as programme facilitators. Regarding programme efficacy, most dyads reported they were better prepared for the future and shared the plans they developed during the programme with family members. CONCLUSION: Implementing a structured information and support programme is feasible, but sustainability requires further adaptation or increased staff resources to maintain programme fidelity. Future research should consider selecting efficacy measures sensitive to the unique needs of people living with dementia and increasing follow-up time to 6 months. IMPACT: This study established the feasibility of registered nurses delivering a post-diagnosis information and support programme for people living with early-stage dementia or mild cognitive impairment and their informal carers in primary care settings. The motivation and capacity of nurses working as programme facilitators ensured the integration of the programme into usual work, but this was not considered sustainable over time. Family carer dyads reported tangible outcomes and gained confidence in sharing their diagnosis with family and friends and asking for assistance. Findings from this study can be used to provide direction for a clinical trial investigating the effectiveness of the structured information and support programme in the primary care setting. REPORTING METHOD: The authors have adhered to the EQUATOR STROBE Statement. PATIENT OR PUBLIC CONTRIBUTION: A public hospital memory clinic and general medical practice participated in project design, study protocol development and supported implementation.

Achievement of therapeutic antibiotic exposures using Bayesian dosing software in critically unwell children and adults with sepsis.

PURPOSE: Early recognition and effective treatment of sepsis improves outcomes in critically ill patients. However, antibiotic exposures are frequently suboptimal in the intensive care unit (ICU) setting. We describe the feasibility of the Bayesian dosing software Individually Designed Optimum Dosing Strategies (ID-ODS™), to reduce time to effective antibiotic exposure in children and adults with sepsis in ICU. METHODS: A multi-centre prospective, non-randomised interventional trial in three adult ICUs and one paediatric ICU. In a pre-intervention Phase 1, we measured the time to target antibiotic exposure in participants. In Phase 2, antibiotic dosing recommendations were made using ID-ODS™, and time to target antibiotic concentrations were compared to patients in Phase 1 (a pre-post-design). RESULTS: 175 antibiotic courses (Phase 1 = 123, Phase 2 = 52) were analysed from 156 participants. Across all patients, there was no difference in the time to achieve target exposures (8.7 h vs 14.3 h in Phase 1 and Phase 2, respectively, p = 0.45). Sixty-one courses in 54 participants failed to achieve target exposures within 24 h of antibiotic commencement (n = 36 in Phase 1, n = 18 in Phase 2). In these participants, ID-ODS™ was associated with a reduction in time to target antibiotic exposure (96 vs 36.4 h in Phase 1 and Phase 2, respectively, p < 0.01). These patients were less likely to exhibit subtherapeutic antibiotic exposures at 96 h (hazard ratio (HR) 0.02, 95% confidence interval (CI) 0.01-0.05, p < 0.01). There was no difference observed in in-hospital mortality. CONCLUSIONS: Dosing software may reduce the time to achieve target antibiotic exposures. It should be evaluated further in trials to establish its impact on clinical outcomes.

A cost-effectiveness evaluation of a dietitian-delivered telephone coaching program during pregnancy for preventing gestational diabetes mellitus.

BACKGROUND: This study aimed to evaluate the cost-effectiveness of a telehealth coaching intervention to prevent gestational diabetes mellitus (GDM) and to calculate the breakeven point of preventing GDM. METHODS: Data to inform the economic evaluation model was sourced directly from the large quaternary hospital in Brisbane, where the Living Well during Pregnancy (LWdP) program was implemented, and further supplemented with literature-based estimates where data had not been directly collected in the trial. A cost-effectiveness model was developed using a decision tree framework to estimate the potential for cost savings and quality of life improvement. A total of 1,315 pregnant women (49% with a BMI 25-29.9, and 51% with a BMI ≥ 30) were included in the analyses. RESULTS: The costs of providing routine care and routine care plus LWdP coaching intervention to pregnant women were calculated to be AUD 20,933 and AUD 20,828, respectively. The effectiveness of the LWdP coaching program (0.894 utility) was slightly higher compared to routine care (0.893). Therefore, the value of the incremental cost-effectiveness ratio (ICER) was negative, and it indicates that the LWdP coaching program is a dominant strategy to prevent GDM in pregnant women. We also performed a probabilistic sensitivity analysis using Monte Carlo simulation through 1,000 simulations. The ICE scatter plot showed that the LWdP coaching intervention was dominant over routine care in 93.60% of the trials using a willingness to pay threshold of AUD 50,000. CONCLUSION: Findings support consideration by healthcare policy and decision makers of telehealth and broad-reach delivery of structured lifestyle interventions during pregnancy to lower short-term costs associated with GDM to the health system.

Sleep problems in a population-based cohort of primary school age children with Cerebral Palsy.

AIMS: To examine sleep problems in a population-based sample of school-aged children (8-12yo) with Cerebral Palsy (CP) METHOD: Eighty-six children (mean 9 years, 5 months, SD = 1 year, 6 months; male = 60) with CP (Gross Motor Function Classification System; GMFCS I=46; II=21; III=9; IV=6; V=6) participated. Classifications/assessments included: Sleep Disturbance Scale for Children (SDSC), Gross Motor Function Measure (GMFM-66), Manual Ability Classification System (MACS), Communication Function Classification System (CFCS), Strengths and Difficulties Questionnaire (SDQ) and the Cerebral Palsy- Quality of Life (CP-QOL) Pain Impact subscale. Analysis included linear and logistic regression. RESULTS: 38 (44 %) children were within the clinical range for sleep problems. Sleep problems were significantly associated with epilepsy, (95 % CI) = 14.48 (7.95 to 21.01), gross motor function, -0.13 (-0.26 to -0.01), manual ability, 7.26 (0.82 to 13.69), communication, 10.01 (2.21 to 17.80), child behaviour, 1.134 (0.74 to 1.53), and pain related QOL, 0.33 (0.12 to 0.53). For the multivariable model, sleep problems remained significantly associated with epilepsy, b (95 % CI) = 11.72 (4.88 to 18.57), child behaviour, 1.03 (0.65 to 1.41) and pain-related QOL, 0.21 (0.29 to 0.38). CONCLUSIONS: Sleep problems are common and associated with epilepsy, child behaviour and pain related QOL.

Cost-Consequence Analysis of Deprescribing to Optimize Health Outcomes for Frail Older People: A Within-Trial Analysis.

OBJECTIVES: The structured, clinically supervised withdrawal of medicines, known as deprescribing, is one strategy to address inappropriate polypharmacy. This study aimed to evaluate the costs and consequences of deprescribing in frail older people living in residential aged care facilities (RACFs) in Australia. DESIGN: A within-trial cost-consequence analysis of a deprescribing intervention-Opti-Med. The Opti-Med double-blind randomized controlled trial of deprescribing included 3 groups: blinded control, blinded intervention, and an open intervention group. SETTING AND PARTICIPANTS: Seventeen RACFs in Western Australia and New South Wales. Participants were 303 older people living in participating RACFs from March 2014 to February 2019. METHODS: Analysis was conducted from the health sector perspective. Health economic outcomes assessed include cost saved from deprescribed medicines and the incremental quality-adjusted life-years. Costs were presented in 2022 Australian dollars. RESULTS: The total cost of the Opti-Med intervention was $239.13 per participant. The costs saved through deprescribed medicines over 12 months after adjusting for mortality within the trial period was $328.90 per participant in the blinded intervention group and $164.00 per participant in the open intervention group. On average, the cost of the intervention was more than offset by the cost saved from deprescribed medicines. Extrapolating these findings to the Australian population suggests a potential net cost saving of about $1 to $16 million per annum for the health system nationally. The incremental quality-adjusted life-years were very similar across the 3 groups within the trial period. CONCLUSIONS AND IMPLICATIONS: Deprescribing for frail older people living in RACFs can be a cost-saving intervention without reducing the quality of life. Systemwide implementation of deprescribing across RACFs in Australia has the potential to improve health care delivery through the cost savings, which could be reapplied to further optimize care within RACFs.

Measuring the success of programmes of care for people living with dementia: a protocol for consensus building with consumers to develop a set of Core Outcome Measures for Improving Care (COM-IC).

INTRODUCTION: The Core Outcome Measures for Improving Care (COM-IC) project aims to deliver practical recommendations on the selection and implementation of a suite of core outcomes to measure the effectiveness of interventions for dementia care. METHODS AND ANALYSIS: COM-IC embeds a participatory action approach to using the Alignment-Harmonisation-Results framework for measuring dementia care in Australia. Using this framework, suitable core outcome measures will be identified, analysed, implemented and audited. The methods for analysing each stage will be codesigned with stakeholders, through the conduit of a Stakeholder Reference Group including people living with dementia, formal and informal carers, aged care industry representatives, researchers, clinicians and policy actors. The codesigned evaluation methods consider two key factors: feasibility and acceptability. These considerations will be tested during a 6-month feasibility study embedded in aged care industry partner organisations. ETHICS AND DISSEMINATION: COM-IC has received ethical approval from The University of Queensland (HREC 2021/HE001932). Results will be disseminated through networks established over the project, and in accordance with both the publication schedule and requests from the Stakeholder Reference Group. Full access to publications and reports will be made available through UQ eSpace (https://espace.library.uq.edu.au/), an open access repository hosted by The University of Queensland.

Investigating community-based care service factors delaying residential care home admission of community dwelling older adults and cost consequence.

OBJECTIVES: To examine factors contributing to delaying care home admission; and compare the rates of care home admission and cost consequence between two government subsidised programmes, Veterans' Affairs Community Nursing (VCN) and Home Care Package (HCP). METHODS: Our national, population-based retrospective cohort study and cost analysis used existing, de-identified veterans' claims databases (2010-19) and the Registry of Senior Australians Historical Cohort (2010-17), plus aggregate programme expenditure data. This involved 21,636 VCN clients (20,980 aged 65-100 years), and an age- and sex-matched HCP cohort (N = 20,980). RESULTS: Service factors associated with lower risk of care home admission in the VCN cohort were periodic (versus continuous) service delivery (HR 0.27 [95%CI, 0.24-0.31] for ≤18 months; HR 0.89 [95%CI, 0.84-0.95] for >18 months), and majority care delivered by registered nurses (versus personal care workers) (HR 0.86 [95%CI, 0.75-0.99] for ≤18 months; HR 0.91 [95%CI, 0.85-0.98] for >18 months). In the matched cohorts, the time to care home admission for VCN clients (median 28 months, IQR 14-42) was higher than for HCP clients (14, IQR 6-27). Within 5 years of service access, 57.6% (95%CI, 56.9-58.4) of HCP clients and 26.6% (95%CI, 26.0-27.2) of VCN clients had care home admission. The estimated cost saving for VCN recipients compared to HCP recipients over 5 years for relevant government providers was over A$1 billion. CONCLUSIONS: Compared to an HCP model, individuals receiving VCN services remained at home longer, with potentially significant cost savings. This new understanding suggests timely opportunity for many countries' efforts to enhance community-based care services.

Participate CP 2: optimising participation in physically active leisure for children with cerebral palsy - protocol for a phase III randomised controlled trial.

INTRODUCTION: Children with cerebral palsy (CP) participate less in physical activities and have increased sedentary behaviour compared with typically developing peers. Participate CP is a participation-focused therapy intervention for children with CP with demonstrated efficacy in a phase II randomised controlled trial (RCT) to increase perceived performance of physical activity participation goals. This study will test the effectiveness of Participate CP in a multisite phase III RCT. METHODS AND ANALYSIS: One hundred children with CP, aged 8-14 years, classified Gross Motor Function Classification System levels I-IV will be randomised to either (1) receive Participate CP once/week for 1 hour for 12 weeks, or (2) waitlist control, usual care group. The waitlist group will then receive Participate CP following the 26-week retention time point. Outcomes will be assessed at baseline, 12 weeks and then 26 weeks post baseline. The primary outcomes are (1) self-reported participation goal performance on the Canadian Occupational Performance Measure at 12 weeks and (2) daily time in moderate-to-vigorous physical activity. Secondary outcomes include home and community participation frequency, involvement and environmental supportiveness, contextual barriers to participation, quality of life, intrinsic motivation for physical activities, child perception of an autonomy-supportive climate for physical activities and physical literacy at 12 and 26 weeks post study entry. ETHICS AND DISSEMINATION: The Children's Health Queensland Hospital and Health Service, The University of Queensland and the New Zealand Health and Disability Ethics Committees have approved this study. Findings will be disseminated in peer-reviewed journals and conference presentations. TRIAL REGISTRATION NUMBER: ACTRN12618000206224.

Development of an age- and comorbidity- adjusted optimal radiotherapy utilisation rate for lung, rectal, prostate and cervical cancers.

INTRODUCTION: Optimal radiotherapy utilisation (RTU) modelling estimates the proportion of people with cancer who would benefit from radiotherapy. Assessment of comorbidities is an important component of the assessment of suitability for radiotherapy in addition to chronological age and life expectancy. Comorbidities have not been considered in previous optimal RTU models. We aimed to develop an age- and comorbidity- adjusted optimal RTU model for patients with lung, rectal, prostate, and cervical cancer, and compare them to actual RTU rates, with a particular focus on those aged 80+ years, METHODS: New South Wales (NSW) Cancer Registry data (2010-2014) linked to radiotherapy data (2010-2015) and hospitalisation data (2008-2015) were used to determine the number of patients diagnosed with lung, rectal, prostate and cervical cancer. The Cancer Specific C3 'all sites' comorbidity index was calculated from hospital diagnosis data for each patient to determine suitability for radiotherapy. The index was then incorporated into a tumour site-specific decision tree model. The actual RTU was also calculated using the linked datasets. RESULTS: 14,696 patients were diagnosed with non-small cell lung cancer (NSCLC), 1839 with small cell lung cancer (SCLC), 5551 with rectal cancer, 30,935 with prostate cancer and 1216 with cervical cancer in New South Wales from 2010-2014. The proportion of patients aged 80+ years at cancer diagnosis was 25% (3603 patients), 15% (279 patients), 17% (943 patients), 12% (3745 patients), and 7% (88 patients) respectively. The age- and comorbidity- adjusted optimal RTU rates for patients aged 80+ years using the C3 index were 49% (NSCLC), 49% (SCLC), 43% (rectal), 51% (prostate) and 40% (cervical). The corresponding actual RTU rates for patients aged 80+ years were 25%, 32%, 27%, 16%, and 56%. CONCLUSION: Even after adjusting for age and comorbidities, the actual radiotherapy utilisation rates were lower than optimal radiotherapy utilisation rates in patients aged 80+ years except for patients with cervical cancer. This warrants further assessment and research into reasons and solutions.

Economic Evaluations of mHealth Interventions for the Management of Type 2 Diabetes: A Scoping Review.

BACKGROUND: There is plenty of evidence supporting the clinical benefits of mHealth interventions for type 2 diabetes, but despite often being promoted as cost-effective or cost-saving, there is still limited research to support such claims. The objective of this review was to summarize and critically analyze the current body of economic evaluation (EE) studies for mHealth interventions for type 2 diabetes. METHODS: Using a comprehensive search strategy, five databases were searched for full and partial EE studies for mHealth interventions for type 2 diabetes from January 2007 to March 2022. "mHealth" was defined as any intervention that used a mobile device with cellular technology to collect and/or provide data or information for the management of type 2 diabetes. The CHEERS 2022 checklist was used to appraise the reporting of the full EEs. RESULTS: Twelve studies were included in the review; nine full and three partial evaluations. Text messages smartphone applications were the most common mHealth features. The majority of interventions also included a Bluetooth-connected medical device, eg, glucose or blood pressure monitors. All studies reported their intervention to be cost-effective or cost-saving, however, most studies' reporting were of moderate quality with a median CHEERS score of 59%. CONCLUSION: The current literature indicates that mHealth interventions for type 2 diabetes can be cost-saving or cost-effective, however, the quality of the reporting can be substantially improved. Heterogeneity makes it difficult to compare study outcomes, and the failure to report on key items leaves insufficient information for decision-makers to consider.

The Medical Outcome Study Social Support Survey (MOS-SSS): A psychometric systematic review.

AIMS: To evaluate and synthesize psychometric properties of the MOS-SSS and to identify quality versions of MOS-SSS for use in future research and practice. DESIGN: A psychometric systematic review. DATA SOURCES: Articles about the translation, adaptation, or validation of the MOS-SSS in Medline, PubMed, CINAHL, and Web of Science and their reference lists published before 11 November 2022. REVIEW METHODS: The review followed the Consensus Standards for the Selection of Health Measurement Instruments guidelines. RESULTS: The review included 35 articles. Eleven versions of MOS-SSS (3, 4, 5, 6, 8, 12, 13, 16, 18, 19, and 22 items) have been validated in various populations and 13 languages. Of 14 studies developing a translated version of MOS-SSS, four studies performed both an experts' evaluation of content validity and a face validity test; two studies reported translation evaluation in the form of a content validity index. Of 35 studies, six performed both exploratory factor analysis and confirmatory factor analysis for structural validity; hypotheses and measurements for construct validity testings were often not clearly stated; two examined criterion validity; and four assessed cross-cultural validity. Internal consistency reliabilities were commonly examined by calculating Cronbach's alpha and reported satisfactory. Five studies analysed test-retest reliabilities using intra correlation coefficient. Methodological concerns exist. CONCLUSION: The English 19-item, Farsi Persian 19-item, and Vietnamese 19-item versions are recommended for future use in research and practice. Italian 19-item and Malaysian 13-item versions are not recommended to be used in future research and practice. All other versions considered in this review have potential use in future research and practice. Proper procedures for developing a translated version of MOS-SSS and validating the scale are recommended. IMPACT: The review identified quality versions of MOS-SSS to measure social support in future research and practice. The study also indicated methodological issues in current validation studies. Application of the study findings and recommendations can be useful to improve outcome measurement quality and maximize the efficiency of resource use in future research and practice. NO PATIENT OR PUBLIC CONTRIBUTION: This systematic review synthesized the evidence from previous research and did not involve any human participation.

Cognitive impairment and health-related quality of life amongst older Australians: evidence from a longitudinal investigation.

INTRODUCTION: Australia's population is steadily growing older, with older persons expected to make up over 20% of the population by 2066. Ageing is strongly associated with a significant drop in cognitive ability, ranging from mild cognitive impairment to severe cognitive impairment (dementia). This study examined the association between cognitive impairment and health-related quality of life (HRQoL) in older Australians. METHODS: Two waves of longitudinal data from the nationally representative Household, Income and Labour Dynamics in Australia (HILDA) survey were utilised, with the age cut-off for older Australians defined as above 50. The final analysis included 10,737 person-year observations from 6892 unique individuals between 2012 and 2016. This study utilised the Backwards Digit Span (BDS) test and Symbol Digit Modalities test (SDMT) to assess cognitive function. HRQoL was measured using the physical and mental component summary scores of the SF-36 Health Survey (PCS and MCS). Additionally, HRQoL was measured using health state utility values (SF-6D score). A longitudinal random-effects GLS regression model was used to analyse the association between cognitive impairment and HRQoL. RESULTS: This study found that approximately 89% of Australian adults aged 50 or older had no cognitive impairment, 10.16% had moderate cognitive impairment, and 0.72% had severe cognitive impairment. This study also found that moderate and severe cognitive impairment were both negatively associated with HRQoL. Older Australians with moderate cognitive impairment scored worse on the PCS (ß = - 1.765, SE = 0.317), MCS (ß = - 1.612, SE = 0.326), and SF-6D (ß = - 0.024, SE = 0.004) than peers without cognitive impairment given other covariates reference categories remain constant. Older adults experiencing severe cognitive had lower PCS (ß = - 3.560, SE = 1.103), and SF-6D (ß = - 0.034, SE = 0.012) scores compared to their counterparts with no cognitive impairment given other covariates reference categories remain constant. CONCLUSION: We found evidence that HRQoL is negatively associated with cognitive impairment. Our findings will be beneficial for the future cost-effectiveness intervention targeted at reducing cognitive impairment since it provides information on the disutility associated with moderate and severe cognitive impairment.
