Disability concentration and access to rehabilitation services: a pilot spatial assessment applying geographic information system analysis

Spatial clusters of potentially preventable hospitalisations and access to allied health services in South Western Sydney: a geospatial study

Objective To explore the association between geographic access to allied health services and potentially preventable hospitalisations. Methods This is a retrospective observational study. Adults aged 18years or older with a potentially preventable hospitalisation for a chronic condition(s) to a public hospital in South Western Sydney Local Health District between 1 July 2016 and 30 June 2019 were identified from the Secure Analytic for Population Health and Intelligence portal at NSW Health. Locations of allied health amenities or practices in the same geographic area were identified from the 2019 National Health Service Directory. Geospatial analysis was used to identify geographic hotspots and coldspots of potentially preventable hospitalisations. Association with access to allied health services was investigated using linear models. Results Hotspots of potentially preventable hospitalisations were significantly more disadvantaged than coldspots. Hotspots also had poorer access to allied health services than coldspots. Conclusion In South Western Sydney, populations with higher burden of chronic disease, as measured through preventable hospitalisations, have poorer access to allied health services than populations with lesser need.

Challenges to accessing behaviour support services for people with intellectual disability before and after the NDIS

BACKGROUND

This study investigated the extent to which behaviour support services are accessible under Australia's National Disability Insurance Scheme (NDIS).

METHOD

We conducted semi-structured interviews with families who support a member with an intellectual disability and challenging behaviour. We analysed this data with a supply and demand access framework initially designed for health care and described the lived experiences of participants and their families accessing behaviour supports. Results show that while the NDIS has improved participants' ability to pay for behaviour (and other) supports, this financial capacity represents only one of six other important aspects of access.

RESULTS

Families compensate for the shortcomings of the marketised environment which has arisen under the NDIS.

CONCLUSION

This raises questions about the responsibilities of support provision, which is obscured in the new NDIS system and places responsibility for successfully accessing behaviour supports onto the family of the person with an intellectual disability.

Examining rehabilitation access disparities: an integrated analysis of electronic health record data and population characteristics through bivariate choropleth mapping

BACKGROUND

Despite efforts to view electronic health records (EHR) data through an equity lens, crucial contextual information regarding patients' social environments remains limited. Integrating EHR data and Geographic Information Systems (GIS) technology can give deeper insights into the relationships between patients' social environments, health outcomes, and geographic factors. This study aims to identify regions with the fastest and slowest access to outpatient physical therapy services using bivariate choropleth maps to provide contextual insights that may contribute to health disparity in access.

METHODS

This was a retrospective cohort study of patients' access timelines for the first visit to outpatient physical therapy services (n = 10,363). The three timelines evaluated were (1) referral-to-scheduled appointment time, (2) scheduled appointment to first visit time, and (3) referral to first visit time. Hot and coldspot analyses (CI 95%) determined the fastest and slowest access times with patient-level characteristics and bivariate choropleth maps that were developed to visualize associations between access patterns and disadvantaged areas using Area Deprivation Index scores. Data were collected between January 1, 2016 and January 1, 2020. EHR data were geocoded via GIS technology to calculate geospatial statistics (Gi∗ statistic from ArcGIS Pro) in an urban area.

RESULTS

Statistically significant differences were found for all three access timelines between coldspot (i.e., fast access group) and hotspot (i.e., slow access group) comparisons (p < .05). The hotspot regions had higher deprivation scores; higher proportions of residents who were older, privately insured, female, lived further from clinics; and a higher proportion of Black patients with orthopaedic diagnoses compared to the coldspot regions.

CONCLUSIONS

Our study identified and described local areas with higher densities of patients that experienced longer access times to outpatient physical therapy services. Integration of EHR and GIS data is a more robust method to identify health disparities in access to care. With this approach, we can better understand the intricate interplay between social, economic, and environmental factors contributing to health disparities in access to care.

Built Environments to Support Rehabilitation for People With Stroke From the Hospital to the Home (B-Sure): Protocol for a Mixed Method Participatory Co-Design Study

BACKGROUND

A global trend is to move rehabilitation closer to people's neighborhoods and homes. Still, little attention has been given to how the built environment outside the hospital setting might impact rehabilitation and recovery for stroke survivors.

OBJECTIVE

The overarching objective of this project is to develop conceptual models of built environments that support stroke rehabilitation and recovery outside the hospital setting. Specifically, the project will explore factors and characteristics of the built environment that support people with stroke and their families and identify innovative built environments that can be designed for local health care. The project will examine facilitators and obstacles for implementing built environmental solutions and evaluate the potential benefits, feasibility, and acceptability.

METHODS

The project uses a mixed methods design approach with 3 phases. In phase 1, factors and characteristics of the built environment for rehabilitation will be identified. Based on the results from phase 1, phase 2 will involve co-designing prototypes of environments to support the rehabilitation process for people with stroke. Finally, the prototypes will be evaluated in phase 3. Qualitative and quantitative methods will include a literature review, a concept mapping (CM) study, stakeholder interviews, prototype development, and testing. The project will use multidimensional scaling, hierarchical cluster analysis, descriptive statistics for quantitative data, and content analysis for qualitative data. Location analysis will rely on the location-allocation model for network problems, and the rule-based analysis will be based on geographic information systems data.

RESULTS

As of the submission of this protocol, ethical approval for the CM study and the interview study has been obtained. Data collection is planned to start in September 2023 and the workshops later in the same year. The scoping review is ongoing from January 2023. The CM study is ongoing and will be finalized in the spring of 2024. We expect to finish the data analysis in the second half of 2024. The project is a 3-year project and will continue until December 2025.

CONCLUSIONS

We aim to determine how new environments could better support a person's control over their day, environment, goals, and ultimately control over their recovery and rehabilitation activities. This "taking charge" approach would have the greatest chance of transferring the care closer to the patient's home. By co-designing with multiple stakeholders, we aim to create solutions with the potential for rapid implementation. The project's outcomes may target other people with frail health after a hospital stay or older persons in Sweden and anywhere else. The impact and social benefits include collaboration between important stakeholders to explore how new environments can support the transition to local health care, co-design, and test of new conceptual models of environments that can promote health and well-being for people post stroke.

Assessment of activities and participation of people by rehabilitation-focused clinical registries: a systematic scoping review

INTRODUCTION

Rehabilitation is considered a key intervention in health care. Clinical registries, defined as an organized system that uses observational methods to collect information to assess specific outcomes in a defined population, can contribute to assessing the impact of the rehabilitation intervention. This review aims to identify and describe rehabilitation-specific registry systems with an emphasis on identifying outcomes that enable the assessment of vital areas and activities of daily living.

EVIDENCE ACQUISITION

A systematic scoping review was conducted. A systematic search was conducted up to August 2022 in MEDLINE/PubMed, Embase, Cochrane Library, Epistemonikos, and other search resources. Studies related to rehabilitation registries presented data on people with health problems that could limit their functioning were selected. The inclusion of studies/clinical registries was not limited by methodological design, year of publication, country, or language. The unit of analysis was rehabilitation registries. The measurement instruments used to assess the outcomes were explored to estimate the domain assessed from the vital areas related to functioning and disability as described by the International Classification of Functioning, Disability and Health (ICF). The vital areas were classified according to activities of daily living (ADLs).

EVIDENCE SYNTHESIS

Seventy-one registries in rehabilitation were identified. The registries included a median of 3 (IQR 2-5) assessment instruments designed to assess the impact of different rehabilitation programs. In total, 137 different assessment scales or instruments were identified. Each rehabilitation registry assessed 6 (IQR 2-8) domains of the ICF, and 15.4% of registries assessed all domains. The most assessed domain was "Mobility" (89.7%), and the least assessed was "General Tasks and Demands" (25.6%). In addition, 92.3% of rehabilitation registries assessed basic ADLs, 76.9% advanced ADLs, and 71.8% instrumental ADLs.

CONCLUSIONS

Although clinical registries do not claim to directly assess the impact of rehabilitation programs on people's functioning according to the ICF framework, it was identified that a low percentage of them assessed the nine vital areas through different outcome assessment instruments. However, most rehabilitation registries directly or indirectly assess some basic, instrumental, and advanced ADLs. The findings of this review highlight the need to improve the design of clinical registries focused on assessing the impact of rehabilitation programs to assess people in all areas of their lives.

Geographic Distribution of Central Nervous System Rehabilitation Treatment in Korea and Its Associated Factors

BACKGROUND

Health disparity is defined as a difference in the accessibility of medical resources among regions or other factors. In South Korea, there might be a disparity because of the low proportion of public medical institutions. This study aimed to investigate the geographic distribution of rehabilitation treatment and examine the factors associated with the rates of rehabilitation treatment in Korea.

METHODS

We used administrative claims data in 2007, 2012, and 2017 from the National Health Insurance Database in Korea. We defined physical therapy and occupational therapy as rehabilitation treatments and analyzed the rate of rehabilitation treatments for administrative districts in 2007, 2012, and 2017. Interdecile range and coefficient of variation were used to investigate the geographic distribution of rehabilitation treatment over time. We applied multiple random intercept negative binomial regression to examine the factors associated with rehabilitation treatment. A total of 28,319,614 inpatient and outpatient claims were submitted for 874 hospitals that provided rehabilitation treatment in 2007, 2012, and 2017.

RESULTS

The increase in the mean rates of physical therapy inpatients and outpatients was greater than those for occupational therapy inpatients and outpatients from 2007 to 2017. Both physical therapy and occupational therapy were concentrated in the Seoul Capital Area and other large urban areas. More than 30% of the districts received no rehabilitation treatment. The interdecile range and coefficient of variation for physical therapy declined more than those for occupational therapy from 2007 to 2017. The deprivation index was negatively correlated with physical therapy inpatients, physical therapy outpatients, occupational therapy inpatients, and occupational therapy outpatients. Furthermore, a 1-unit increase in the number of hospital beds per 1,000 people was associated with 1.42 times higher physical therapy inpatient, 1.44 times higher physical therapy outpatient, 2.14 times higher occupational therapy inpatient, and 3.30 times higher occupational therapy outpatient treatment.

CONCLUSION

To reduce the geographic inequality in rehabilitation treatment, it is necessary to narrow the gap between the supply and demand of rehabilitation services. Providing incentives or direct provisions from the government might be an alternative.

The application of spatial measures to analyse health service accessibility in Australia: a systematic review and recommendations for future practice

BACKGROUND

Australia's inequitable distribution of health services is well documented. Spatial access relates to the geographic limitations affecting the availability and accessibility of healthcare practitioners and services. Issues associated with spatial access are often influenced by Australia's vast landmass, challenging environments, uneven population concentration, and sparsely distributed populations in rural and remote areas. Measuring access contributes to a broader understanding of the performance of health systems, particularly in rural/remote areas. This systematic review synthesises the evidence identifying what spatial measures and geographic classifications are used and how they are applied in the Australian peer-reviewed literature.

METHODS

A systematic search of peer-reviewed literature published between 2002 and 2022 was undertaken using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Search terms were derived from three major topics, including: [1] Australian population; [2] spatial analysis of health service accessibility; and [3] objective physical access measures.

RESULTS

Database searches retrieved 1,381 unique records. Records were screened for eligibility, resulting in 82 articles for inclusion. Most articles analysed access to primary health services (n = 50; 61%), followed by specialist care (n = 17; 21%), hospital services (n = 12; 15%), and health promotion and prevention (n = 3; 4%). The geographic scope of the 82 articles included national (n = 33; 40%), state (n = 27; 33%), metropolitan (n = 18; 22%), and specified regional / rural /remote area (n = 4; 5%). Most articles used distance-based physical access measures, including travel time (n = 30; 37%) and travel distance along a road network (n = 21; 26%), and Euclidean distance (n = 24; 29%).

CONCLUSION

This review is the first comprehensive systematic review to synthesise the evidence on how spatial measures have been applied to measure health service accessibility in the Australian context over the past two decades. Objective and transparent access measures that are fit for purpose are imperative to address persistent health inequities and inform equitable resource distribution and evidence-based policymaking.

Are Social Determinants of Health Associated With Onset of Rehabilitation Services in Patients Hospitalized for Traumatic Brain Injury?

OBJECTIVE

To examine the impact of community-level social determinants of health (SDoH) on the onset of occupational therapy (OT) and physical therapy (PT) services among individuals hospitalized for traumatic brain injury (TBI).

SETTING

14 acute care hospitals in the state of Colorado.

PARTICIPANTS

We studied 5825 adults with TBI.

DESIGN

In a secondary analysis of de-identified electronic health record data, we performed multivariable logistic and linear regressions to calculate odds ratios (ORs) and 95% CIs for the likelihood of receiving services and duration to initiation of services among those who received them.

MAIN MEASURES

Community-level SDoH, receipt of rehabilitation services, and onset of rehabilitation services.

RESULTS

Multivariable logistic and linear regressions revealed that those in top quartiles for community income were associated with duration to OT services, ranging from OR = 0.33 [05% CI, 0.07, 0.60] for quartile 2 to 0.76 [0.44, 1.08] for quartile 4 compared with those with the lowest quartile. Only the top quartile differed significantly for duration to PT services (0.63 [0.28, 0.98]). Relative to those with below the median community percentage of high school degree, those with above the median were associated with duration to PT services only (-0.32 [-0.60, -0.04]). Neither community percentage with bachelor's degree nor rural-urban designation was associated with duration to either therapy service.

CONCLUSION

Further research is needed to determine whether our SDoH variables were too diffuse to capture individual experiences and impacts on care or whether community-level education and income, and rurality, truly do not influence time to therapy for patients hospitalized with TBI. Other, individual-level variables, such as age, comorbidity burden, and TBI severity, demonstrated clear relationships with therapy onset. These findings may help therapists evaluate and standardize equitable access to timely rehabilitation services.

Regional maldistribution of human resources of rehabilitation institutions in China Mainland based on spatial analysis

Objective

With the demand for rehabilitation has been increasing faster for the aging of China's population, the equity of rehabilitation resource has aroused great concern. This study aimed to analyze the spatial distribution and evolution of the human resources of rehabilitation institutions and propose targeted countermeasures and suggestions to promote optimal allocation.

Methods

A total of 31 provinces in China Mainland were identified and geocoded. The spatial weight matrix was introduced to analyze the spatial correlation. Spatial autocorrelation analysis and tests were used to analyze the spatial distribution and evolution characteristics of rehabilitation institutions' human resources in China from 2016 to 2019.

Results

The average density of rehabilitation staff from 2016 to 2019 has been rising yearly (From 1.60 to 1.88). From 2018 to 2019, the proportion of rehabilitation professionals was higher than 75% in only 5 provinces, and no provinces met 75% from 2016 to 2017. Global Moran's I index from 2016 to 2019 showed no apparent aggregation phenomenon in the allocation of management personnel resources (P > 0.05). Three provinces in western China belonged to the Low-Low area and a province in northeastern China fitted to the Low-High area, with statistically significant differences. In addition, the changes in the spatial distribution and evolution trend of the human resources of rehabilitation institutions in different periods were affected by health policies.

Conclusions

Although the overall spatial distribution gap of human resource allocation of rehabilitation institutions is shrinking, there are still internal structural defects and a maldistribution at the provincial level. It is necessary to improve the overall number of staff in rehabilitation institutions and to ameliorate the proportion of different types of staffing.

Planning with care complexity: Factors related to discharge delays of hospitalised people with disability

Planning for discharge and supports beyond hospital for people with disability in Australia involves negotiation of complex care systems. The aims of this study were to examine how the individualised support pathway of the National Disability Insurance Scheme (NDIS) functioned for admitted people with disability who required funded support to leave hospital; and to explore the factors indicative of increased care complexity associated with delays. Retrospective chart reviews of people with disability were conducted. Data on 198 eligible patients were extracted, including NDIS plan approval and plan implementation timeframes and discharge delay. Participants' median age was 52 years (interquartile range = 41-59). The most common disability type was spinal cord injury (41%). The median NDIS plan approval and implementation timeframes were 89 days (63-123) and 39 days (8-131), respectively, and most participants (72%) experienced a delayed discharge. A longer plan implementation timeframe was associated with higher odds of a delay in discharge (OR = 3.41, 95% credible interval = 1.56, 7.11). We did not find any evidence that plan approval timeframe, or any other variable indicative of increased care complexity, was associated with discharge delays. Our findings suggest that a delayed discharge will likely be the reality for people with disability who require funded supports to leave hospital. They also suggest that NDIS plan implementation is a major challenge and a focus for policy and practice improvements. To target solutions, further research should focus on the interactions and negotiations of the multiple intermediaries involved and resource and structural impediments to plan implementation.

The impact of obstacles to health and rehabilitation services on functioning and disability: a prospective survey on the 12-months after discharge from specialist rehabilitation for acquired brain injury

PURPOSE

Little is known about obstacles to health and rehabilitation services experienced by people with acquired brain injury (ABI) over time and what impact these have on recovery. This study utilised the International Classification of Functioning, Disability, and Health model to better understand the impact of service obstacles. The aims were: (1) describe and compare service obstacles reported in the 12-months post-discharge from inpatient rehabilitation; (2) examine service obstacles as a moderator of the relationship between functional impairment and activities and participation.

MATERIALS AND METHODS

Prospective survey of 41 people who received ABI inpatient rehabilitation in Queensland, Australia. Validated self-report measures of service obstacles, functional impairment, and activities and participation were administered at 6- and 12-months post-discharge.

RESULTS

Transportation was the highest-rated obstacle at 6-months post-discharge, and this decreased at 12-months. Dissatisfaction with treatment resources and financial obstacles were, on average, low-to-moderate and remained constant. Specifically, the moderation analyses showed that financial obstacles may exacerbate the negative impact of functional impairment on independent living skills.

CONCLUSIONS

Our findings suggest that people living in Queensland, Australia, who experience financial obstacles to services after brain injury may be at risk of poorer recovery outcomes. Rehabilitation policy should consider prioritising individuals who experience financial obstacles to accessing services.IMPLICATIONS FOR REHABILITATIONIn Queensland, Australia, financial obstacles to accessing health services after brain injury may exacerbate the negative impact of functional impairment on independent living skills, in the first 12-months after hospital discharge.There may be a need to prioritize rehabilitation policy that targets individuals who experience financial obstacles to accessing health and rehabilitation services, after brain injury, irrespective of a health system's potential to enable access.

Applying Environmental Context to Rehabilitation Research Using Geographic Information Systems and Global Positioning Systems Geospatial Technologies

Background

The International Classification of Functioning, Disability, and Health includes important considerations of environmental context in understanding disability, but the environmental impact is often difficult to measure.

Purpose

Demonstrates the use of Geographic Information Systems (GIS) and Global Positioning Systems (GPS) in rehabilitation research in assessing accessibility and participation; describes how to use these methods, and presents several considerations in using GIS and GPS in research.

Method

Using methods from public health and medical geography, this article describes how to apply GIS and GPS technologies to rehabilitation research to measure community participation and accessibility to resources.

Findings

Directions for using ArcGIS functions and case examples joining these mapping technologies with rehabilitation measures are provided.

Conclusions

Together with traditional measures, these technologies may provide rehabilitation researchers a more comprehensive approach to assessing accessibility and participation.

Area-Level Associations between Built Environment Characteristics and Disability Prevalence in Australia: An Ecological Analysis

The importance of health-promoting neighborhoods has long been recognized, and characteristics of local built environments are among the social determinants of health. People with disability are more likely than other population groups to experience geographic mobility and cost restrictions, and to be reliant on 'opportunity structures' available locally. We conducted an ecological analysis to explore associations between area-level disability prevalence for people aged 15-64 years and area-level built environment characteristics in Australia's 21 largest cities. Overall, disability was more prevalent in areas with lower walkability and lower local availability of various neighborhood amenities such as public transport, healthier food options, public open space, physical activity and recreation destinations and health and mental health services. These patterns of lower liveability in areas of higher disability prevalence were observed in major cities but not in regional cities. Our findings suggest that geographically targeted interventions to improve access to health-enhancing neighborhood infrastructure could reduce disability-related inequalities in the social determinants of health.

Using the maximum clustering heterogeneous set-proportion to select the maximum window size for the spatial scan statistic

The spatial scan statistic has been widely used to detect spatial clusters that are of common interest in many health-related problems. However, in most situations, different scan parameters, especially the maximum window size (MWS), result in obtaining different detected clusters. Although performance measures can select an optimal scan parameter, most of them depend on historical prior or true cluster information, which is usually unavailable in practical datasets. Currently, the Gini coefficient and the maximum clustering set-proportion statistic (MCS-P) are used to select appropriate parameters without any prior information. However, the Gini coefficient may be unstable and select inappropriate parameters, especially in complex practical datasets, while the MCS-P may have unsatisfactory performance in spatial datasets with heterogeneous clusters. Based on the MCS-P, we proposed a new indicator, the maximum clustering heterogeneous set-proportion (MCHS-P). A simulation study of selecting the optimal MWS confirmed that in spatial datasets with heterogeneous clusters, the MWSs selected using the MCHS-P have much better performance than those selected using the MCS-P; moreover, higher heterogeneity led to a larger advantage of the MCHS-P, with up to 538% and 69.5% improvement in the Youden's index and misclassification in specific scenarios, respectively. Meanwhile, the MCHS-P maintains similar performance to that of the MCS-P in spatial datasets with homogeneous clusters. Furthermore, the MCHS-P has significant improvements over the Gini coefficient and the default 50% MWS, especially in datasets with clusters that are not far from each other. Two practical studies showed similar results to those obtained in the simulation study. In the case where there is no prior information about the true clusters or the heterogeneity between the clusters, the MCHS-P is recommended to select the MWS in order to accurately identify spatial clusters.

Trajectories of Rehabilitation across Complex Environments (TRaCE): design and baseline characteristics for a prospective cohort study on spinal cord injury and acquired brain injury

PURPOSE

Trajectories of Rehabilitation across Complex Environments (TRaCE), a consented prospective cohort study, addresses a critical need to better understand access to the healthcare system after acute treatment and specialist inpatient rehabilitation for acquired disability. It is expected that this study will produce new knowledge on access to healthcare through the linkage of administrative, survey, and spatial datasets on the one cohort. This paper outlines the study design and baseline characteristics of the cohort.

METHODS

The TRaCE cohort is comprised of 165 inpatients who are currently being followed up for 12 months after discharge from specialist rehabilitation for acquired brain injury (ABI) and spinal cord injury (SCI). This project combines a data linkage framework on health service use with a prospective survey on psychosocial wellbeing, geographical information systems to examine spatial accessibility to services, and qualitative interviews with a sub-cohort on experiences of service access.

CONCLUSION

Ultimately, TRaCE will have strong translational impact on strategies for more targeted interventions to improve the healthcare system and support individuals with acquired disabilities in the long-term.
