A method to determine spatial access to specialized palliative care services using GIS

Geographic Information Systems Utilization in Pediatric End-of-Life Research: A Scoping Review

Currently, little is known about how geographic information systems (GIS) has been utilized to study end-of-life care in pediatric populations. The purpose of this review was to collect and examine the existing evidence on how GIS methods have been used in pediatric end-of-life research over the last 20 years. Scoping review method was used to summarize existing evidence and inform research methods and clinical practice was used. The Preferred Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA) was utilized. The search resulted in a final set of 17 articles. Most studies created maps for data visualization and used ArcGIS as the primary software for analysis. The scoping review revealed that GIS methodology has been limited to mapping, but that there is a significant opportunity to expand the use of this methodology for pediatric end-of-life care research.

Survey of Palliative Care Use in Primary Malignant Bone Tumors: A National Cancer Database Review

Background/Objectives: Palliative care (PC) has been associated with reduced patient symptom burden, improved physician satisfaction, and reduced cost of care. However, its use in primary bone tumors has not been well classified. Design/Setting and Subjects: Patients diagnosed with primary malignant bone tumors (osteosarcoma, chondrosarcoma, Ewing sarcoma, and chordoma) between 2004 and 2018 were identified in the National Cancer Database. Cross tabulations with chi-square analysis were performed to evaluate frequencies of PC use by patient, facility, and tumor characteristics. Multivariate logistic binary regression was performed to evaluate relationships between patient, treatment facility, and tumor characteristics and the use of PC. Results: Around 24,401 patients were identified. Overall, 2.52% had any form of PC utilization. Of those receiving PC, 55.5-65.1% were treated with only noncurative surgery, radiation, chemotherapy, or any combination of these modalities. Odds of PC utilization were decreased for patients with chordomas, patients living >24 miles from the treatment facility, or patients with private insurance, Medicare, or unknown insurance status. Odds of PC utilization were increased in patients with greater tumor diameter or unknown tumor size, tumors in midline, increased tumor grade, stage IV tumors, or living in urban areas. Conclusion: PC use in patients with primary bone tumors increases with tumor stage, tumor grade, tumor size, and if the tumor is midline, and in patients living in urban areas. However, overall utilization remains markedly low. Future studies should be done to investigate these patterns of care and help expand the utilization of PC.

Accessibility to specialist palliative care services in Germany: a geographical network analysis

BACKGROUND

The need for palliative care will increase over the next years because of the rise in deaths from chronic illness and demographic changes. The provision of specialist palliative care (SPC) in Germany (palliative care units (PCU), specialist palliative home care (SPHC) teams and palliative care advisory (PCA) teams) has been expanded in recent years. Despite the increasing availability, there is still insufficient coverage with long travel times. The aim was to describe the spatial distribution of SPC services in Germany, to calculate the potential accessibility of facilities and to assess potential spatial under-provision.

METHODS

Retrospective cross-sectional study with regional analysis of SPC services in Germany. Addresses of SPC services registered online were geocoded, accessibility and network analyses were conducted, and proportion of the population living up to 60 minutes driving time were calculated.

RESULTS

A total of 673 facilities were included. Their distribution is heterogeneous with every fourth of the 401 districts (110/401; 27.4%) lacking a SPC service. In half of the area of Germany the existing PCU and SPHC teams are within reach of 30 minutes, with nearly 90% of the population living there. Hospitals providing PCA teams can be reached within 30 minutes in 17% of the total area with provision for 43% of the population.

CONCLUSIONS

A high coverage of SPHC teams and PCU indicates a good spatial distribution in Germany but no complete adequate provision of SPC services, especially for PCA teams. There is a persistent need for further implementation of hospital PCA teams.

Characterization of prehospital time delay in primary percutaneous coronary intervention for acute myocardial infarction: analysis of geographical infrastructure-dependent and -independent components

BACKGROUND

Prehospital delay in reaching a percutaneous coronary intervention (PCI) facility is a major problem preventing early coronary reperfusion in patients with ST-elevation myocardial infarction (STEMI). The aim of this study was to identify modifiable factors that contribute to the interval from symptom onset to arrival at a PCI-capable center with a focus on geographical infrastructure-dependent and -independent factors.

METHODS

We analyzed data from 603 STEMI patients who received primary PCI within 12 h of symptom onset in the Hokkaido Acute Coronary Care Survey. We defined onset-to-door time (ODT) as the interval from the onset of symptoms to arrival at the PCI facility and we defined door-to-balloon time (DBT) as the interval from arrival at the PCI facility to PCI. We analyzed the characteristics and factors of each time interval by type of transportation to PCI facilities. In addition, we used geographical information system software to calculate the minimum prehospital system time (min-PST), which represents the time required to reach a PCI facility based on geographical factors. We then subtracted min-PST from ODT to find the estimated delay-in-arrival-to-door (eDAD), which represents the time required to reach a PCI facility independent of geographical factors. We investigated the factors related to the prolongation of eDAD.

RESULTS

DBT (median [IQR]: 63 [44, 90] min) was shorter than ODT (median [IQR]: 104 [56, 204] min) regardless of the type of transportation. However, ODT was more than 120 min in 44% of the patients. The min-PST (median [IQR]: 3.7 [2.2, 12.0] min) varied widely among patients, with a maximum of 156 min. Prolongation of eDAD (median [IQR]: 89.1 [49, 180] min) was associated with older age, absence of a witness, onset at night, no emergency medical services (EMS) call, and transfer via a non-PCI facility. If eDAD was zero, ODT was projected to be less than 120 min in more than 90% of the patients.

CONCLUSIONS

The contribution of geographical infrastructure-dependent time in prehospital delay was substantially smaller than that of geographical infrastructure-independent time. Intervention to shorten eDAD by focusing on factors such as older age, absence of a witness, onset at night, no EMS call, and transfer via a non-PCI facility appears to be an important strategy for reducing ODT in STEMI patients. Additionally, eDAD may be useful for evaluating the quality of STEMI patient transport in areas with different geographical conditions.

Value of Geographical Information Systems in Analyzing Geographic Accessibility to Inform Radiotherapy Planning: A Systematic Review

PURPOSE

Vulnerable populations face geographical barriers in accessing radiotherapy (RT) facilities, resulting in heterogeneity of care received and cancer burden faced. We aimed to explore the current use of Geographical Information Systems (GIS) in access to RT and use these findings to create sustainable solutions against barriers for access in low- and middle-income countries.

MATERIALS AND METHODS

A systematic review using the PRISMA search strategy was done for studies using GIS to explore outcomes among patients with cancer. Included studies were reviewed and classified into three umbrella categories of how GIS has been used in studying access to RT.

RESULTS

Forty articles were included in the final review. Thirty-eight articles were set in high-income countries and two in upper-middle-income countries. Included studies were published from 2000 to 2020, and were comprised of patients with all-cancers combined, breast, colon, skin, lung, prostate, ovarian, and rectal carcinoma patients. Studies were categorized under three groups on the basis of how they used GIS in their analyses: to describe geographic access to RT, to associate geographic access to RT with outcomes, and for RT planning. Most studies fell under multiple categories.

CONCLUSION

Although this field is relative nascent, there is a wide array of functions possible through GIS for RT planning, including identifying high-risk populations, improving access in high-need areas, and providing valuable information for future resource allocation. GIS should be incorporated in future studies, especially set in low- and middle-income countries, which evaluate access to RT.

Utilization of Palliative Care in Osteosarcoma: A National Cancer Database Review

Background: Osteosarcoma is the most common form of bone cancer, but the utilization of palliative care (PC) in patients with this cancer has not previously been investigated in the National Cancer Database (NCDB). Methods: Patients diagnosed with osteosarcoma (2004-2017) were identified within the NCDB. Cross tabulations with Chi-square analysis were performed to evaluate frequencies of palliative care use by patient, facility, and tumor characteristics. Multivariate logistic binary regression was performed to evaluate relationships between patient, treatment facility, and tumor characteristics and the use of palliative care. Results: A total of 7498 patients were analyzed with 2.8% of patients diagnosed having any form of palliative care utilization. Of this group, 53.37% received PC within the first 12 months after diagnosis. Of the 2.8% of patients receiving PC the most common forms of PC utilized were non-curative symptom-directed surgery, radiation, or chemotherapy, or a combination of these modalities (56.7%). Palliative care usage was increased in patients with greater tumor diameter, tumors in the bones of the midline, or stage IV tumors. Palliative care usage was decreased in patients living within 25-49 miles of their treatment facility, those living in pacific states, those with chondroblastic osteosarcoma, or those with private insurance. Conclusion: Palliative care use in patients with osteosarcoma increases with tumor stage, tumor size, or more proximal tumors, but overall utilization remains markedly low. Future studies should further define these patterns of care and help expand the utilization of PC.

Study on Spatial Distribution Equilibrium of Elderly Care Facilities in Downtown Shanghai

With the growing challenge of aging populations around the world, the study of the care services for older adults is an essential initiative to accommodate the particular needs of the disadvantaged communities and promote social equity. Based on open-source data and the geographic information system (GIS), this paper quantifies and visualizes the imbalance in the spatial distribution of elderly care facilities in 14,578 neighborhoods in downtown (seven districts) Shanghai, China. Eight types of elderly care facilities were obtained from Shanghai elderly care service platform, divided into two categories according to their service scale. With the introduction of the improved Gaussian 2-step floating catchment area method, the accessibility of two category facilities was calculated. Through the global autocorrelation analysis, it is found that the accessibility of elderly care facilities has the characteristics of spatial agglomeration. Local autocorrelation analysis indicates the cold and hot spots in the accessibility agglomeration state of the two types of facilities, by which we summarized the characteristics of their spatial heterogeneity. It is found that for Category−I, there is a large range of hot spots in Huangpu District. For Category−II, the hot-spot and cold-spot areas show staggered distribution, and the two categories of hot spot distribution show a negative correlation. We conclude that the two categories are not evenly distributed in the urban area, which will lead to the low efficiency of resource allocation of elderly care facilities and have a negative impact on social fairness. This research offers a systematic method to study urban access to care services for older adults as well as a new perspective on improving social fairness.

Socio-Spatial Disparities in County-Level Availability of Aging and Disability Services Organizations

Aging and disability services are essential for supporting older adults in living independently in their homes and communities as they age. Applying theoretical perspectives of community gerontology and spatial inequality, we use county-level data (N=3142) from the National Neighborhood Data Archive (NaNDA) and the American Community Survey to explore if and how availability of aging and disability services organizations varies across the rural-urban continuum and across compositional characteristics of counties. Results show that rural counties are significantly more likely to be aging and disability services deserts. Stratified models show that poverty rates and relative shares of non-Hispanic Blacks are positively associated with greater odds of aging and disability services deserts across rural and urban counties, but divergent findings appear for county-level shares of Hispanics. These findings are discussed as well as implications for research, policy, and practice on equitable access to aging and disability services.

Geographic variation in diagnostic and treatment interval, cancer stage and mortality among colorectal patients - An international comparison between Denmark and Scotland using data-linked cohorts

BACKGROUND

Rurald wellers with colorectal cancer have poorer outcomes than their urban counterparts. The reasons why are not known but are likely to be complex and be determined by an interplay between geography and health service organization. By comparing the associations related to travel-time to primary and secondary healthcare facilities in two neighbouring countries, Denmark and Scotland, we aimed to shed light on potential mechanisms.

METHODS

Analysis was based on two comprehensive cohorts of patients diagnosed with colorectal cancer in Denmark (2010-16) and Scotland (2007-14). Associations between travel-time and cancer pathway intervals, tumour stage at diagnosis and one-year mortality were analysed using generalised linear models. Travel-time was modelled using restricted cubic splines for each country and combined. Adjustments were made for key confounders.

RESULTS

Travel-time to key healthcare facilities influenced the diagnostic experience and outcomes of CRC patients from Scotland and Denmark to some extent differently. The longest travel-times to a specialised hospital appeared to afford the most rapid secondary care interval, whereas moderate travel-times to hospital (about 20-60 min) appeared to impact on later stage and greater one-year mortality in Scotland, but not in Denmark. A U-shaped association was seen between travel-time to the GP and one year-mortality.

CONCLUSIONS

This is the first international data-linkage study to explore how different national geographies and health service structures may determine cancer outcomes. Future research should compare more countries and more cancer sites and evaluate the impact and implications of differences in national health service organisation.

Population's Potential Accessibility to Specialized Palliative Care Services: A Comparative Study in Three European Countries

BACKGROUND

Palliative care is a priority for health systems worldwide, yet equity in access remains unknown. To shed light on this issue, this study compares populations' driving time to specialized palliative care services in three countries: Ireland, Spain, and Switzerland.

METHODS

Network analysis of the population's driving time to services according to geolocated palliative care services using Geographical Information System (GIS). Percentage of the population living within a 30-min driving time, between 30 and 60 minutes, and over 60 min were calculated.

RESULTS

The percentage of the population living less than thirty minutes away from the nearest palliative care provider varies among Ireland (84%), Spain (79%), and Switzerland (95%). Percentages of the population over an hour away from services were 1.87% in Spain, 0.58% in Ireland, and 0.51% in Switzerland.

CONCLUSION

Inequities in access to specialized palliative care are noticeable amongst countries, with implications also at the sub-national level.

Different configurations of the two-step floating catchment area method for measuring the spatial accessibility to hospitals for people living with disability: a cross-sectional study

BACKGROUND

Poor spatial accessibility to hospital services is associated with higher morbidity and mortality rates among people living with disability. Improved methods to evaluate spatial accessibility are needed. This study measured the potential spatial accessibility of people living with disability by applying four configurations of the two-step floating catchment area (2SFCA) method to recommend the best model for use in health services research.

METHODS

2SFCA and an enhanced version (E2SFCA) were used to measure hospital accessibility for people living with disability. We also developed and embedded a non-spatial severity index into the two 2SFCA models. We used 16,186 records of people living with disability experience to evaluate the methodological performance across 68 neighbourhoods of the city of Ahvaz, located in south-western Iran. The models' performance were measured through correlation of the four accessibility scores with the distance to closest hospital for each neighbourhood centroid.

RESULTS

Among the four models used to measure spatial accessibility, the E2SFCA integrated with the severity index displayed the best performance. Most people with disabilities lived in neighbourhoods located in the South-western and central areas of the city. Interestingly, south-western neighbourhoods had poor hospital accessibility score and were identified as unmet need areas for access to health services.

CONCLUSIONS

Inclusion of the severity factor in the E2SFCA improved access measurements. Identifying areas with poor levels of hospital accessibility can help policymakers design tailored interventions and improve accessibility to hospital-based care in urban settings for people living with disability.

Where to enhance rural palliative care? Developing a spatial model to identify suitable communities most in need of service enhancement

Background

In Canada, access to palliative care is a growing concern, particularly in rural communities. These communities have constrained health care services and accessing local palliative care can be challenging. The Site Suitability Model (SSM) was developed to identify rural “candidate” communities with need for palliative care services and existing health service capacity that could be enhanced to support a secondary palliative care hub. The purpose of this study was to test the feasibility of implementing the SSM in Ontario by generating a ranked summary of rural “candidate” communities as potential secondary palliative care hubs.

Methods

Using Census data combined with community-level data, the SSM was applied to assess the suitability of 12 communities as rural secondary palliative care hubs. Scores from 0 to 1 were generated for four equally-weighted components: (1) population as the total population living within a 1-h drive of a candidate community; (2) isolation as travel time from that community to the nearest community with palliative care services; (3) vulnerability as community need based on a palliative care index score; and (4) community readiness as five dimensions of fit between a candidate community and a secondary palliative care hub. Component scores were summed for the SSM score and adjusted to range from 0 to 1.

Results

Population scores for the 12 communities ranged widely (0.19–1.00), as did isolation scores (0.16–0.94). Vulnerability scores ranged more narrowly (0.27–0.35), while community readiness scores ranged from 0.4–1.0. These component scores revealed information about each community’s particular strengths and weaknesses. Final SSM scores ranged from a low of 0.33 to a high of 0.76.

Conclusions

The SSM was readily implemented in Ontario. Final scores generated a ranked list based on the relative suitability of candidate communities to become secondary palliative care hubs. This list provides information for policy makers to make allocation decisions regarding rural palliative services. The calculation of each community’s scores also generates information for local policy makers about how best to provide these services within their communities. The multi-factorial structure of the model enables decision makers to adapt the relative weights of its components.

Inequality in geographical distribution of hospitals and hospital beds in densely populated metropolitan cities of Iran

Background

This study aims to assess geographical distribution of hospitals and extent of inequalities in hospital beds against socioeconomic status (SES) of residents of five metropolitan cities in Iran.

Methods

A cross-sectional analysis was conducted to measure geographical inequality in hospital and hospital bed distributions of 68 districts in five metropolitan cities during 2016 using geographic information system (GIS), and Gini and Concentration indices. Correlation analysis was performed to show the relationship between the SES and inequality in hospital beds densities.

Results

The study uncovered marked inequalities in hospitals and hospital beds distributions. The Gini indices for hospital beds were greater than 0.55. The aggregated concentration indices for public and private hospital beds were 0.33 and 0.49, respectively. The GIS revealed that 216 (70.6%) hospitals were located in two highest socioeconomic status classes in the cities. Only 29 (9.5%) hospitals were located in the lowest class. The public, private, and the cumulative hospitals beds distributions in Tehran and Esfahan showed significant (p < 0.05) positive correlation with SES of the residents.

Conclusions

The high inequalities in hospital and hospital beds distributions in our study imply an overlooked but growing concern for geographical access to healthcare in rapidly urbanizing metropolitan cities in Iran. Thus, regardless of ownership, decision-makers should emphasize the disadvantaged areas in metropolitan cities when need arises for the establishment of new healthcare facilities in order to ensure fairness in healthcare. The metropolitan cities and rapid urbanization settings in other countries could learn lessons to reduce or prevent similar issues which might have hampered access to healthcare.

Urban and rural differences in geographical accessibility to inpatient palliative and end-of-life (PEoLC) facilities and place of death: a national population-based study in England, UK

BACKGROUND

Little is known about the role of geographic access to inpatient palliative and end of life care (PEoLC) facilities in place of death and how geographic access varies by settlement (urban and rural). This study aims to fill this evidence gap.

METHODS

Individual-level death data in 2014 (N = 430,467, aged 25 +) were extracted from the Office for National Statistics (ONS) death registry and linked to the ONS postcode directory file to derive settlement of the deceased. Drive times from patients' place of residence to nearest inpatient PEoLC facilities were used as a proxy estimate of geographic access. A modified Poisson regression was used to examine the association between geographic access to PEoLC facilities and place of death, adjusting for patients' socio-demographic and clinical characteristics. Two models were developed to evaluate the association between geographic access to inpatient PEoLC facilities and place of death. Model 1 compared access to hospice, for hospice deaths versus home deaths, and Model 2 compared access to hospitals, for hospital deaths versus home deaths. The magnitude of association was measured using adjusted prevalence ratios (APRs).

RESULTS

We found an inverse association between drive time to hospice and hospice deaths (Model 1), with a dose-response relationship. Patients who lived more than 10 min away from inpatient PEoLC facilities in rural areas (Model 1: APR range 0.49-0.80; Model 2: APR range 0.79-0.98) and urban areas (Model 1: APR range 0.50-0.83; Model 2: APR range 0.98-0.99) were less likely to die there, compared to those who lived closer (i.e. ≤ 10 min drive time). The effects were larger in rural areas compared to urban areas.

CONCLUSION

Geographic access to inpatient PEoLC facilities is associated with where people die, with a stronger association seen for patients who lived in rural areas. The findings highlight the need for the formulation of end of life care policies/strategies that consider differences in settlements types. Findings should feed into local end of life policies and strategies of both developed and developing countries to improve equity in health care delivery for those approaching the end of life.

Palliative Care Use Among Patients With Solid Cancer Tumors: A National Cancer Data Base Study

BACKGROUND

Palliative care has been increasingly recognized as an important part of cancer care but remains underutilized in patients with solid cancers. There is a current gap in knowledge regarding why palliative care is underutilized nationwide.

OBJECTIVE

To identify the factors associated with palliative care use among deceased patients with solid cancer tumors.

METHODS

Using the 2016 National Cancer Data Base, we identified deceased patients (2004-2013) with breast, colon, lung, melanoma, and prostate cancer. Data were described as percentages. Associations between palliative care use and patient, facility, and geographic characteristics were evaluated through multivariate logistic regression.

RESULTS

A total of 1 840 111 patients were analyzed; 9.6% received palliative care. Palliative care use was higher in the following patient groups: survival >24 months (17% vs 2%), male (54% vs 46%), higher Charlson-Deyo comorbidity score (16% vs 8%), treatment at designated cancer programs (74% vs 71%), lung cancer (76% vs 28%), higher grade cancer (53% vs 24%), and stage IV cancer (59% vs 13%). Patients who lived in communities with a greater percentage of high school degrees had higher odds of receiving palliative care; Central and Pacific regions of the United States had lower odds of palliative care use than the East Coast. Patients with colon, melanoma, or prostate cancer had lower odds of palliative care than patients with breast cancer, whereas those with lung cancer had higher odds.

CONCLUSIONS

Palliative care use in solid cancer tumors is variable, with a preference for patients with lung cancer, younger age, known insurance status, and higher educational level.

Scaling the Peaks Research Protocol: understanding the barriers and drivers to providing and using dementia-friendly community services in rural areas-a mixed methods study

INTRODUCTION

Scaling the Peaks is a cross-disciplinary research study that draws on medical ethnography, human geography and Geospatial Information Science (GIS) to address the issues surrounding the design and delivery of dementia-friendly services in rural communities. The research question seeks to understand the barriers and drivers to the development of relevant, robust, reliable and accessible services that make a difference among older rural families affected by dementia.

METHODS AND ANALYSIS

This mixed methods study recruits both families affected by dementia who reside within the Peak District National Park, Derbyshire, and their service providers. The study explores the expectations and experiences of rural dementia by adopting a three-part approach ¹ : longitudinal ethnographic enquiry with up to 32 families affected by dementia (aged 70 years plus) who identify themselves as rural residents ² ; ethnographic semistructured interviews and systematic observations of a range of statutory, third sector, private and local community initiatives that seek to support older people living with dementia ³ ; and geospatial visual mapping of the qualitative and quantitative data. The ethnographic data will be used to explore the ideas of belonging in a community, perceptions of place and identity to determine the factors that influence everyday decisions about living well with dementia and, for the providers, working in a rural community. The geospatial component of the study seeks to incorporate quantitative and qualitative data, such as types, locations and allocation of services to produce an interactive web-based map for local communities to determine the future design and delivery of services when considering dementia-friendly services.

ETHICS AND DISSEMINATION

The study is approved by the Leeds and Humberside Health Research Authority 16/YH/0163. The study is also approved by other participating organisations as required by their own governance procedures. The study includes people with dementia and as such adheres to the ethical considerations when including people with dementia. A publicly available interactive visual map of the findings will be produced in relation to current services related to location and, by default, identify gaps in provision. Formal reports and dissemination activities will be undertaken in collaboration with the study advisory group members.

STUDY PROGRESS

The recruitment began in September 2016. The data analysis commenced June 2017, using 59 provider interviews and 27 family participants. Data collection will be completed June 2018.

NOTE ON TERMINOLOGY

Please note that the term 'families affected by dementia' is the preferred term of usage by the family members of the Scaling the Peaks Study Advisory Group. The group wish to emphasise that they consider this term to be more representative of their lives than the term living with dementia.

Community readiness and momentum: identifying and including community-driven variables in a mixed-method rural palliative care service siting model

BACKGROUND

Health service administrators make decisions regarding how to best use limited resources to have the most significant impact. Service siting models are tools that can help in this capacity. Here we build on our own mixed-method service siting model focused on identifying rural Canadian communities most in need of and ready for palliative care service enhancement through incorporating new community-driven insights.

METHODS

We conducted 40 semi-structured interviews with formal and informal palliative care providers from four purposefully selected rural communities across Canada. Communities were selected by running our siting model, which incorporated GIS methods, and then identifying locations suitable as qualitative case studies. Participants were identified using multiple recruitment methods. Interviews were transcribed verbatim and the transcripts were reviewed to identify emerging themes and were coded accordingly. Thematic analysis then ensued.

RESULTS

We previously introduced the inclusion of a 'community readiness' arm in the siting model. This arm is based on five community-driven indicators of palliative care service enhancement readiness and need. The findings from the current analysis underscore the importance of this arm of the model. However, the data also revealed the need to subjectively assess the presence or absence of community awareness and momentum indicators. The interviews point to factors such as educational tools, volunteers, and local acknowledgement of palliative care priorities as reflecting the presence of community awareness and factors such as new employment and volunteer positions, new care spaces, and new projects and programs as reflecting momentum. The diversity of factors found to illustrate these indicators between our pilot study and current national study demonstrate the need for those using our service siting model to look for contextually-relevant signs of their presence.

CONCLUSION

Although the science behind siting model development is established, few researchers have developed such models in an open way (e.g., documenting every stage of model development, engaging with community members). This mixed-method study has addressed this notable knowledge gap. While we have focused on rural palliative care in Canada, the process by which we have developed and refined our siting model is transferrable and can be applied to address other siting problems.

The Determinants of Palliative Care Use in Patients With Colorectal Cancer: A National Study

BACKGROUND

Palliative care is associated with improved survival and quality of life, but its use among patients with colorectal cancer varies nationwide and the determinants of those variations are not clear.

OBJECTIVE

To determine the factors associated with palliative care use among patients who died of colorectal cancer.

METHODS

Deceased patients treated for colorectal cancer (2004-2013) were identified within the National Cancer Database. Multivariable logistic regression was used to evaluate patient and institutional characteristics associated with palliative care use. Patients were classified based on their length of survival (<6 months, 6-24 months, and 24+ months) to provide timing context.

RESULTS

A total of 287 923 patients were analyzed. Overall, 4.3% of the patients received palliative care. Patients who received palliative care were more likely to be younger, recently diagnosed, treated at academic hospitals, and have stage IV disease. Patients living in Mountain and Pacific regions had higher odds of palliative care receipt than those in the East Coast. Patients without insurance had higher odds of palliative care if they survived <24 months. Insurance coverage through Medicaid was associated with increased palliative care use among patients who survived 6 to 24 months. Patients who survived <6 months and lived >9 miles from the institution received more palliative care.

CONCLUSION

Palliative care use among patients with colorectal cancer is associated with a younger age, a more recent year of diagnosis, insurance status, academic hospitals, and living in Mountain and Pacific regions.

Geographic assessment of access to health care in patients with cardiovascular disease in South Africa

Background

Noncommunicable diseases (NCDs) including cardiovascular diseases (CVDs), diabetes, cancer and chronic lung disease are increasingly emerging as major contributors to morbidity and mortality in developing countries. For example, in South Africa, 195 people died per day between 1997 and 2004 from CVDs related causes. Access to efficient and effective health facility and care is an important contributing factor to overall population health and addressing prognosis, care and management CVD disease burden. This study aimed to spatially evaluate geographic health care access of people diagnosed with CVD to health facilities and to evaluate the density of the existing health facility network in South Africa.

Methods

Data was obtained from the National Income Dynamics Study (NIDS) conducted in 4 waves (phases) between 2008 and 2014. The participants who responded as having heart problems that were diagnosed by a health practitioner were extracted for use in this study. Network analyst in ArcGIS ® was used to generate a least-cost path, which refers to the best path that one can travel. The residential locations of participants diagnosed with heart problems were put into the network analysis model as origins and the location of health facilities were destinations. District averages were used to protect the identity of studied participants.

Results

There were a total of 51, 42, 43, 43 health districts out the 52 that had recorded subjects with a heart condition in the 2008, 2010–2011, 2012 and 2014–2015 waves, respectively. The mean distance from a case household to a health facility per wave was 2, 2.3, 2.1 and 2.1 km in 2008, 2010–2011 and 2014–2015 respectively. The maximum individual distances travelled per wave were 41.4 km, 40,5 km, 44,2 km and 39.6 km for the 2008, 2010–2011, 2012 and 2014–2015 waves respectively. For district level analysis, participants with CVD residing in the districts found to be among the poorest in the country travelled the longest distances. These were located in the provinces of Limpopo and KwaZulu Natal. It was also found that districts with large proportions of their population living in rural settings had among the lowest densities of health facilities. Significant percentages of study participants were exposed to numerous CVD risk factors, the commonly reported one being high blood pressure. A lack of regular exercise was also commonly reported in each of the waves.

Conclusion

A lack of accessible healthcare in already impoverished municipalities could result in an increase lack of timely diagnosis, CVD case management. This could result in increased CVD-related morbidity and mortality. GIS methods have the potential to assist national health programs to develop policies that target issues such as areas or populations being underserved by health facilities and populations that must travel long distances to receive healthcare. These policies will be key in preventing and controlling the emerging CVD burden through an accessible primary healthcare system for early detection and case management.

Geographic Information Systems Mapping of Diabetic Retinopathy in an Ocular Telemedicine Network

Importance

Minimal information exists on the use of geographic information systems mapping for visualizing access barriers to eye care for patients with diabetes.

Objective

To use geographic information systems mapping techniques to visualize (1) the locations of patients participating in the North Carolina Diabetic Retinopathy Telemedicine Network, (2) the locations of primary care clinicians and ophthalmologists across the state, and (3) the travel times associated with traveling to the 5 primary care clinics in our study.

Design, Setting, and Participants

Cross-sectional study conducted from January 6, 2014, to November 1, 2015, at 5 Area Health Education Center primary care clinics that serve rural and underserved populations in North Carolina. In total, 1787 patients with diabetes received retinal screening photographs with remote expert interpretation to determine the presence and severity of diabetic retinopathy. Participants included patients 18 years or older with type 1 or type 2 diabetes who presented to these 5 clinics for their routine diabetes care.

Main Outcomes and Measures

Development of qualitative maps illustrating the density of patients with diabetes and their distribution around the 5 North Carolina Diabetic Retinopathy Telemedicine Network sites by zip code and the density of ophthalmologists and primary care clinicians by zip code relative to US Census Urban Areas. A travel time map was also created using road network analysis to determine all areas that can be reached by car in a user-specified amount of time.

Results

Mean (SD) age of patients was 55.4 (12.7) years. Women made up 62.7% of the study population. The study included more African American patients (55.4%) compared with white (35.5%) and Hispanic (5.8%) patients. The mean (SD) hemoglobin A1c level was 7.8% (2.4%) (to convert to proportion of total hemoglobin, multiply by 0.01), and the mean (SD) duration of diabetes was 9.2 (8.2) years. Whereas the clinics located in Greensboro, Asheville, and Fayetteville screened patients from more immediate surrounding areas, the Greenville site had the widest distribution of zip codes, suggesting that patients travel from greater distances to reach this facility. Primary care clinicians were spread somewhat uniformly across the state, whereas ophthalmologists were concentrated around urban centers. Also, the number and type of surface roads surrounding the clinics determined the distance and time patients must travel to receive care.

Conclusions and Relevance

Geographic information systems mapping is a useful technique for visualizing geographic access barriers to eye care for patients with diabetes and may help to identify underserved areas that would benefit from the expansion of retinal screening programs via telemedicine.

Geographical Variation and Factors Associated with Non-Small Cell Lung Cancer in Manitoba

Background

Screening decreases non-small cell lung cancer (NSCLC) deaths and is recommended by the Canadian Task Force on Preventive Health Care. We investigated risk factor prevalence and NSCLC incidence at a small region level to inform resource allocation for lung cancer screening.

Methods

NSCLC diagnoses were obtained from the Canadian Cancer Registry, then geocoded to 283 small geographic areas (SGAs) in Manitoba. Sociodemographic characteristics of SGAs were obtained from the 2006 Canadian Census and Canadian Community Health Survey. Geographical variation was modelled using a Bayesian spatial Poisson model.

Results

NSCLC incidence in SGAs ranged from 1 to 343 cases per 100,000 population per year. The highest incidence rates were in the Southeastern, Southwestern, and Central regions of Manitoba, while most of Northern Manitoba had lower rates. Poisson regression suggested areas with higher proportions of Aboriginal people and higher average income, and immigrants had lower NSCLC incidence whereas areas with higher proportions of smokers had higher incidence.

Conclusion

On an SGA level, smoking rates remain the most significant factor driving NSCLC incidence. Socioeconomic status and proportions of immigrants or Aboriginal peoples independently impact NSCLC rates. We have identified SGAs in Manitoba to target in policy and infrastructure planning for lung cancer screening.

Measurement of special access to home visit nursing services among Japanese disabled elderly people: using GIS and claim data

BACKGROUND

Home care service demands are increasing in Japan; this necessitates improved service allocation. This study examined the relationship between home visit nursing (HVN) service use and the proportion of elderly people living within 10 min' travel of HVN agencies.

METHODS

The population of elderly people living within reach of HVN agencies for each of 17 municipalities in one low-density prefecture was calculated using public data and geographic information systems. Multilevel logistic analysis for 2641 elderly people was conducted using medical and long-term care insurance claims data from October 2010 to examine the association between the proportion of elderly people reachable by HVNs and service usage in 13 municipalities. Municipality variables included HVN agency allocation appropriateness. Individual variables included HVN usage and demographic variables.

RESULTS

The reachable proportion of the elderly population ranged from 0.0 to 90.2% in the examined municipalities. The reachable proportion of the elderly population was significantly positively correlated with HVN use (odds ratio: 1.938; confidence interval: 1.265-2.967).

CONCLUSIONS

Residents living in municipalities with a lower reachable proportion of the elderly population are less likely to use HVN services. Public health interventions should increase the reachable proportion of the elderly population in order to improve HVN service use.

Measuring geographical accessibility to palliative and end of life (PEoLC) related facilities: a comparative study in an area with well-developed specialist palliative care (SPC) provision

BACKGROUND

Geographical accessibility is important in accessing healthcare services. Measuring it has evolved alongside technological and data analysis advances. High correlations between different methods have been detected, but no comparisons exist in the context of palliative and end of life care (PEoLC) studies. To assess how geographical accessibility can affect PEoLC, selection of an appropriate method to capture it is crucial. We therefore aimed to compare methods of measuring geographical accessibility of decedents to PEoLC-related facilities in South London, an area with well-developed SPC provision.

METHODS

Individual-level death registration data in 2012 (n = 18,165), from the Office for National Statistics (ONS) were linked to area-level PEoLC-related facilities from various sources. Simple and more complex measures of geographical accessibility were calculated using the residential postcodes of the decedents and postcodes of the nearest hospital, care home and hospice. Distance measures (straight-line, travel network) and travel times along the road network were compared using geographic information system (GIS) mapping and correlation analysis (Spearman rho).

RESULTS

Borough-level maps demonstrate similarities in geographical accessibility measures. Strong positive correlation exist between straight-line and travel distances to the nearest hospital (rho = 0.97), care home (rho = 0.94) and hospice (rho = 0.99). Travel times were also highly correlated with distance measures to the nearest hospital (rho range = 0.84-0.88), care home (rho = 0.88-0.95) and hospice (rho = 0.93-0.95). All correlations were significant at p < 0.001 level.

CONCLUSIONS

Distance-based and travel-time measures of geographical accessibility to PEoLC-related facilities in South London are similar, suggesting the choice of measure can be based on the ease of calculation.

Assessing access to paediatric trauma centres in Canada, and the impact of the golden hour on length of stay at the hospital: an observational study

OBJECTIVES

In Canada injuries are a leading cause of death and morbidity among the paediatric population. Trauma systems have been established across North America to provide comprehensive injury care and to lead injury control efforts. However, not all populations have equal access to trauma care services. This is an observational study with the aim of assessing the impact of geographical access to paediatric trauma centres (PTCs) on patient outcomes, and to determine spatial access to PTCs across Canada.

SETTING

To examine the relationship between access to PTC and injury outcome, length of stay at the PTC was determined for all injured patients who live within and outside of 60 min driving time of the PTC. To determine spatial access to PTCs across Canada, a list of level 1 and 2 PTCs was identified across Canada. A 1 h driving time catchment was created around each PTC in order to estimate spatial accessibility.

PARTICIPANTS

Hospital administration data sets from British Columbia (BC) and the Nova Scotia (NS) trauma registry were used to assess the impact of spatial access on paediatric injury (ages 0-15 years) outcomes. The data sets provided case-level data including the Injury Severity Score, postal code of place of residence, age and length of hospital stay.

RESULTS

In NS and BC, average length of stay at the hospital is significantly lower inside 60 min driving time compared to outside of 60 min driving time from a PTC (p<0.05, using a non-parametric t test). In Canada, approximately 65% of the paediatric population resides within 1 h of a PTC.

CONCLUSIONS

This paper highlights differences in injury outcomes as a result of access. However, further investigation is needed as other considerations such as type of injury, age and/or gender may also affect injury outcomes.

Use of geographic information systems to assess the error associated with the use of place of residence in injury research

Background

In any spatial research, the use of accurate location data is critical to the reliability of the results. Unfortunately, however, many of the administrative data sets used in injury research do not include the location at which the injury takes place. The aim of this paper is to examine the error associated with using place of residence as opposed to place of injury when identifying injury hotspots and hospital access.

Methods

Traumatic Brian Injury (TBI) data from the BC Trauma Registry (BCTR) was used to identify all TBI patients admitted to BC hospitals between January 2000 and March 2013. In order to estimate how locational error impacts the identification of injury hotspots, the data was aggregated to the level of dissemination area (DA) and census tract (CT) and a linear regression was performed using place of residence as a predictor for place of injury.

In order to assess the impact of locational error in studies examining hospital access, an analysis of the driving time between place of injury and place of residence and the difference in driving time between place of residence and the treatment hospital, and place of injury and the same hospital was conducted.

Results

The driving time analysis indicated that 73.3 % of the injuries occurred within 5 min of place of residence, 11.2 % between five and ten minutes and 15.5 % over 20 min. Misclassification error occurs at both the DA and CT level. The residual map of the DA clearly shows more detailed misclassification.

As expected, the driving time between place of residence and place of injury and the difference between these same two locations and the treatment hospital share a positive relationship. In fact, the larger the distance was between the two locations, the larger the error was when estimating access to hospital.

Conclusions

Our results highlight the need for more systematic recording of place of injury as this will allow researchers to more accurately pinpoint where injuries occur. It will also allow researchers to identify the causes of these injuries and to determine how these injuries might be prevented.

A comparative analysis of potential spatio-temporal access to palliative care services in two Canadian provinces

BACKGROUND

Access to health services such as palliative care is determined not only by health policy but a number of legacies linked to geography and settlement patterns. We use GIS to calculate potential spatio-temporal access to palliative care services. In addition, we combine qualitative data with spatial analysis to develop a unique mixed-methods approach.

METHODS

Inpatient health care facilities with dedicated palliative care beds were sampled in two Canadian provinces: Newfoundland and Saskatchewan. We then calculated one-hour travel time catchments to palliative health services and extended the spatial model to integrate available beds as well as documented wait times.

RESULTS

26 facilities with dedicated palliative care beds in Newfoundland and 69 in Saskatchewan were identified. Spatial analysis of one-hour travel times and palliative beds per 100,000 population in each province showed distinctly different geographical patterns. In Saskatchewan, 96.7% of the population living within a-1 h of drive to a designated palliative care bed. In Newfoundland, 93.2% of the population aged 65+ were living within a-1 h of drive to a designated palliative care bed. However, when the relationship between wait time and bed availability was examined for each facility within these two provinces, the relationship was found to be weak in Newfoundland (R(2) = 0.26) and virtually nonexistent in Saskatchewan (R(2) = 0.01).

CONCLUSIONS

Our spatial analysis shows that when wait times are incorporated as a way to understand potential spatio-temporal access to dedicated palliative care beds, as opposed to spatial access alone, the picture of access changes.

Clinical epidemiology and treatment patterns of patients with multicentric Castleman disease: results from two US treatment centres

Multicentric Castleman disease (MCD) is a rare lymphoproliferative disease with little known about its epidemiology or treatment modalities. Clinical and demographic data of MCD patients identified between 2000 and 2009 were collected from medical records at two United States (US) MCD referral centres. ZIP codes identified patient residences; prevalence and incidence were estimated based on catchment areas. Patient clinical, demographic, and biochemical characteristics, drug therapies and medical utilization were descriptively reported. MCD patients (n = 59) were 61% male, mean age of 53 years (median = 55 years) and 68% Caucasian. Of those with known human immunodeficiency virus (HIV) status (n = 41), 85% (n = 35) were negative, 15% (n = 6) were positive. Most frequent physician-reported symptoms (n = 33) were fatigue (49%, n = 16), fever (39%, n = 13), and night sweats (30%, n = 10). The estimated US 10-year prevalence was 2·4 per million. During first year of follow-up after study entry, the top two systemic therapies (n = 27) were monotherapies: prednisone (33%, n = 9) and rituximab (19%, n = 5). After a follow-up of 2 years, 92% of patients were alive. This study provides new information on MCD population demographics, treatment patterns, and medical utilization; a minimal US period prevalence rate is proposed. Study replication is needed to improve external validity.

Referral patterns and proximity to palliative care inpatient services by level of socio-economic disadvantage. A national study using spatial analysis

Background

A range of health outcomes at a population level are related to differences in levels of social disadvantage. Understanding the impact of any such differences in palliative care is important. The aim of this study was to assess, by level of socio-economic disadvantage, referral patterns to specialist palliative care and proximity to inpatient services.

Methods

All inpatient and community palliative care services nationally were geocoded (using postcode) to one nationally standardised measure of socio-economic deprivation – Socio-Economic Index for Areas (SEIFA; 2006 census data). Referral to palliative care services and characteristics of referrals were described through data collected routinely at clinical encounters. Inpatient location was measured from each person’s home postcode, and stratified by socio-economic disadvantage.

Results

This study covered July – December 2009 with data from 10,064 patients. People from the highest SEIFA group (least disadvantaged) were significantly less likely to be referred to a specialist palliative care service, likely to be referred closer to death and to have more episodes of inpatient care for longer time. Physical proximity of a person’s home to inpatient care showed a gradient with increasing distance by decreasing levels of socio-economic advantage.

Conclusion

These data suggest that a simple relationship of low socioeconomic status and poor access to a referral-based specialty such as palliative care does not exist. Different patterns of referral and hence different patterns of care emerge.

Variation in geographic access to specialist inpatient hospices in England and Wales

We seek to map and describe variation in geographic access to the set of 189 specialist adult inpatient hospices in England and Wales. Using almost 35,000 small Census areas (Local Super Output Areas: LSOAs) as our units of analysis, the locations of hospices, and estimated drive times from LSOAs to hospices we construct an accessibility 'score' for each LSOA, for England and Wales as a whole. Data on cancer mortality are used as a proxy for the 'demand' for hospice care and we then identify that subset of small areas in which accessibility (service supply) is relatively poor yet the potential 'demand' for hospice services is above average. That subset is then filtered according to the deprivation score for each LSOA, in order to identify those LSOAs which are also above average in terms of deprivation. While urban areas are relatively well served, large parts of England and Wales have poor access to hospices, and there is a risk that the needs of those living in relatively deprived areas may be unmet.

A Literature Review on Care at the End-of-Life in the Emergency Department

The hospitalisation and management of patients at the end-of-life by emergency medical services is presenting a challenge to our society as the majority of people approaching death explicitly state that they want to die at home and the transition from acute care to palliation is difficult. In addition, the escalating costs of providing care at the end-of-life in acute hospitals are unsustainable. Hospitals in general and emergency departments in particular cannot always provide the best care for patients approaching end-of-life. The main objectives of this paper are to review the existing literature in order to assess the evidence for managing patients dying in the emergency department, and to identify areas of improvement such as supporting different models of care and evaluating those models with health services research. The paper identified six main areas where there is lack of research and/or suboptimal policy implementation. These include uncertainty of treatment in the emergency department; quality of life issues, costs, ethical and social issues, interaction between ED and other health services, and strategies for out of hospital care. The paper concludes with some areas for policy development and future research.

Optimizing the two-step floating catchment area method for measuring spatial accessibility to medical clinics in Montreal

BACKGROUND

Reducing spatial access disparities to healthcare services is a growing priority for healthcare planners especially among developed countries with aging populations. There is thus a pressing need to determine which populations do not enjoy access to healthcare, yet efforts to quantify such disparities in spatial accessibility have been hampered by a lack of satisfactory measurements and methods. This study compares an optimised and the conventional version of the two-step floating catchment area (2SFCA) method to assess spatial accessibility to medical clinics in Montreal.

METHODS

We first computed catchments around existing medical clinics of Montreal Island based on the shortest network distance. Population nested in dissemination areas were used to determine potential users of a given medical clinic. To optimize the method, medical clinics (supply) were weighted by the number of physicians working in each clinic, while the previous year's medical clinic users were computed by ten years age group was used as weighting coefficient for potential users of each medical clinic (demand).

RESULTS

The spatial accessibility score (SA) increased considerably with the optimisation method. Within a distance of 1 Km, for instance, the maximum clinic accessible for 1,000 persons is 2.4 when the conventional method is used, compared with 27.7 for the optimized method. The t-test indicates a significant difference between the conventional and the optimized 2SFCA methods. Also, results of the differences between the two methods reveal a clustering of residuals when distance increases. In other words, a low threshold would be associated with a lack of precision.

CONCLUSION

Results of this study suggest that a greater effort must be made ameliorate spatial accessibility to medical clinics in Montreal. To ensure that health resources are allocated in the interest of the population, health planners and the government should consider a strategy in the sitting of future clinics which would provide spatial access to the greatest number of people.

Quantitative measurements of inequality in geographic accessibility to pediatric care in Oita Prefecture, Japan: standardization with complete spatial randomness

BACKGROUND

A quantitative measurement of inequality in geographic accessibility to pediatric care as well as that of mean distance or travel time is very important for priority setting to ensure fair access to pediatric facilities. However, conventional techniques for measuring inequality is inappropriate in geographic settings. Since inequality measures of access distance or travel time is strongly influenced by the background geographic distribution patterns, they cannot be directly used for regional comparisons of geographic accessibility. The objective of this study is to resolve this issue by using a standardization approach.

METHODS

Travel times to the nearest pediatric care were calculated for all children in Oita Prefecture, Japan. Relative mean differences were considered as the inequality measure for secondary medical service areas, and were standardized with an expected value estimated from a Monte Carlo simulation based on complete spatial randomness.

RESULTS

The observed mean travel times in the area considered averaged 4.50 minutes, ranging from 1.83 to 7.02 minutes. The mean of the observed inequality measure was 1.1, ranging from 0.9 to 1.3. The expected values of the inequality measure varied according to the background geographic distribution pattern of children, which ranged from 0.3 to 0.7. After standardizing the observed inequality measure with the expected one, we found that the ranks of the inequality measure were reversed for the observed areas.

CONCLUSIONS

Using the indicator proposed in this paper, it is possible to compare the inequality in geographic accessibility among regions. Such a comparison may facilitate priority setting in health policy and planning.

Dying in the margins: understanding palliative care and socioeconomic deprivation in the developed world

CONTEXT

Individuals from low socioeconomic (SE) groups have less resources and poorer health outcomes. Understanding the nature of access to appropriate end-of-life care services for this group is important.

OBJECTIVES

To evaluate the literature in the developed world for barriers to access for low SE groups.

METHODS

Electronic databases searched in the review included MEDLINE (1996-2010), CINAHL (1996-2010), PsychINFO (2000-2010), Cochrane Library (2010), and EMBASE (1996-2010). Publications were searched for key terms "socioeconomic disadvantage," "socioeconomic," "poverty," "poor" paired with "end-of-life care," "palliative care," "dying," and "terminal Illness." Articles were analyzed using existing descriptions for dimensions of access to health services, which include availability, affordability, acceptability, and geographical access.

RESULTS

A total of 67 articles were identified for the literature review. Literature describing end-of-life care and low SE status was limited. Findings from the review were summarized under the headings for dimensions of access.

CONCLUSION

Low SE groups experience barriers to access in palliative care services. Identification and evaluation of interventions aimed at reducing this disparity is required.

Access to trauma systems in Canada

BACKGROUND

Trauma is a leading cause of morbidity, potential years of life lost and health care expenditure in Canada and around the world. Trauma systems have been established across North America to provide comprehensive injury care and to lead injury control efforts. We sought to describe the current status of trauma systems in Canada and Canadians' access to acute, multidisciplinary trauma care.

METHODS

A national survey was used to identify the locations and capabilities of adult trauma centers across Canada and to identify the catchment populations they serve. Geographic information science methods were used to map the locations of Level I and Level II trauma centers and to define 1-hour road travel times around each trauma center. Data from the 2006 Canadian Census were used to estimate populations within and outside 1-hour access to definitive trauma care.

RESULTS

In Canada, 32 Level I and Level II trauma centers provide definitive trauma care and coordinate the efforts of their surrounding trauma systems. Most Canadians (77.5%) reside within 1-hour road travel catchments of Level I or Level II centers. However, marked geographic disparities in access persist. Of the 22.5% of Canadians who live more than an hour away from a Level I or Level II trauma centers, all are in rural and remote regions.

DISCUSSION

Access to high quality acute trauma care is well established across parts of Canada but a clear urban/rural divide persists. Regional efforts to improve short- and long-term outcomes after severe trauma should focus on the optimization of access to pre-hospital care and acute trauma care in rural communities using locally relevant strategies or novel care delivery options.

Issues in rural palliative care: views from the countryside

CONTEXT

Growing concern exists among health professionals over the dilemma of providing necessary health care for Canada's aging population. Hospice palliative services are an essential need in both urban and rural settings. Rural communities, in particular, are vulnerable to receiving inadequate services due to their geographic isolation.

PURPOSE

To better understand experiences and issues related to rural palliative care.

METHODS

Focus groups were held for health professionals, family members and volunteers in 3 rural British Columbia communities. A coding schema was developed and the data were then thematically analyzed using a constant comparison technique.

FINDINGS

Three themes in rural palliative care were established: nature of palliative health care services, nature of rural relationships, and competencies required for rural palliative care. Findings indicated that the diversity in rural communities requires tailored approaches to palliative care that consider the geographic, cultural and health aspects of residents in order to optimize care.

CONCLUSION

Tailored approaches to palliative care developed in conjunction with rural communities are needed in order to optimize care.

'Heated political dynamics exist ...': examining the politics of palliative care in rural British Columbia, Canada

Palliative care is delivered by a number of professional groups and informal providers across a range of settings. This arrangement works well in that it maximizes avenues for providing care, but may also bring about complicated 'politics' due to struggles over control and decision-making power. Thirty-one interviews conducted with formal and informal palliative care providers in a rural region of British Columbia, Canada, are drawn upon as a case study. Three types of politics impacting on palliative care provision are identified: inter-community, inter-site, and inter-professional. Three themes crosscut these politics: ownership, entitlement, and administration. The politics revealed by the interviews, and heretofore underexplored in the palliative literature, have implications for the delivery of palliative care. For example, the outcomes of the politics simultaneously facilitate (e.g. by promoting advocacy for local services) and serve as a barrier to (e.g. by privileging certain communities/care sites/provider) palliative care provision.

Providers' perceptions of Aboriginal palliative care in British Columbia's rural interior

Aboriginal Canadians experience a disproportionate burden of ill-health and have endured a history of racism in accessing and using health care. Meanwhile, this population is rapidly growing, resulting in an urgent need to facilitate better quality of living and dying in many ways, including through enhancing (cultural) access to palliative care. In this article, we report the findings from a qualitative case study undertaken in rural British Columbia, Canada through exploring the perceptions of Aboriginal palliative care in a region identified as lacking in formal palliative care services and having only a limited Aboriginal population. Using interview data collected from 31 formal and informal palliative care providers (May-September 2008), we thematically explore not only the existing challenges and contradictions associated with the prioritisation and provision of Aboriginal palliative care in the region in terms of (in)visibility but also identify the elements necessary to enhance such care in the future. The implications for service providers in rural regions are such that consideration of the presence of small, and not always 'visible', populations is necessary; while rural care providers are known for their resilience and resourcefulness, increased opportunities for meaningful two-way knowledge exchange with peers and consultation with experts cannot be overlooked. Doing so will serve to enhance culturally accessible palliative care in the region in general and for Aboriginal peoples specifically. This analysis thus contributes to a substantial gap in the palliative care literature concerning service providers' perceptions surrounding Aboriginal palliative care as well as Aboriginal peoples' experiences with receiving such care. Given the growing Aboriginal population and continued health inequities, this study serves to not only increase awareness but also create better living and dying conditions in small but incremental ways.

A protocol for determining differences in consistency and depth of palliative care service provision across community sites

Numerous accounts document the difficulty in obtaining accurate data regarding the extent and composition of palliative care services. Compounding the problem is the lack of standardisation regarding categorisation and reporting across jurisdictions. In this study, we gathered both quantitative and spatial--or geographical--data to develop a composite picture that captures the extent, composition and depth of palliative care in the Canadian province of British Columbia (BC). The province is intensely urban in the southwest and is rural or remote in most of the remainder. For this study, we conducted a detailed telephone survey of all palliative care home care teams and facilities hosting designated beds in BC. We used geographic information systems to geocode locations of all hospice and hospital facilities. In-home care data was obtained individually from each of five BC regional health authorities. In addition, we purchased accurate road travel time data to determine service areas around palliative facilities and to determine populations outside of a 1-hour travel time to a facility. With this data, we were able to calculate three critical metrics: (i) the population served within 1 hour of palliative care facilities--and more critically those not served; (ii) a matrix that determines access to in-home palliative care measured by both diversity of professionals as well as population served per palliative team member; and (iii) a ranking of palliative care services across the province based on physical accessibility as well as the extent of in-home care. In combination, these metrics provide the basis for identifying areas of vulnerability with respect to not meeting potential palliative care need. In addition, the ranking provides a basis for rural/urban comparisons. Finally, the protocol introduced can be used in other areas and provides a means of comparing palliative care service provision amongst multiple jurisdictions.

On the road again: patient perspectives on commuting for palliative care

OBJECTIVE

The aim of this research project was to gain an understanding of the experiences of rural cancer patients who commute to an urban cancer center for palliative care.

METHOD

The study utilized a mixed method design. Fifteen individuals with a palliative designation participated in semi-structured interviews and filled out the Problems and Needs in Palliative Care Questionnaire.

RESULTS

Qualitative findings included three major themes: cultures of rural life and care, strategies for commuting, and the effects of commuting. Participants valued their rural lifestyles and gained significant support from their communities. Strategies included preparing for the trip with particular attention to pain management, making the most of time, and maintaining significant relationships. Establishing a routine helped to offset the anxiety of commuting. Commuting was costly but the quality of life and supportive relationships obtained through treatment were significant benefits. Questionnaire data suggested that participants were experiencing a number of problems but few indicated they desired more professional attention to those problems.

SIGNIFICANCE OF RESULTS

Rural lifestyles are often an important part of overall well-being and commuting for care is both costly and complex. Health care providers should assist individuals to weigh the relative contributions of staying in their rural locale versus commuting for care to their overall quality of life. Palliative-care individuals in this study indicated a number of ongoing problems but were not inclined to seek further assistance from health care providers in addressing those problems. Clinicians should actively inquire about problems and further research is needed to understand why patients are reluctant to seek help.

Access to primary percutaneous coronary intervention for ST-segment elevation myocardial infarction in Canada: a geographic analysis

BACKGROUND

Primary percutaneous coronary intervention (PCI) is preferred over fibrinolysis for the treatment of ST-segment elevation myocardial infarction (STEMI). In the United States, nearly 80% of people aged 18 years and older have access to a PCI facility within 60 minutes. We conducted this study to evaluate the areas in Canada and the proportion of the population aged 40 years and older with access to a PCI facility within 60, 90 and 120 minutes.

METHODS

We used geographic information systems to estimate travel times by ground transport to PCI facilities across Canada. Time to dispatch, time to patient and time at the scene were considered in the overall access times. Using 2006 Canadian census data, we extracted the number of adults aged 40 years and older who lived in areas with access to a PCI facility within 60, 90 and 120 minutes. We also examined the effect on these estimates of the hypothetical addition of new PCI facilities in underserved areas.

RESULTS

Only a small proportion of the country's geographic area was within 60 minutes of a PCI facility. Despite this, 63.9% of Canadians aged 40 and older had such access. This proportion varied widely across provinces, from a low of 15.8% in New Brunswick to a high of 72.6% in Ontario. The hypothetical addition of a single facility to each of 4 selected provinces could increase the proportion by 3.2% to 4.3%, depending on the province. About 470 000 adults would gain access in such a scenario of new facilities.

INTERPRETATION

We found that nearly two-thirds of Canada's population aged 40 years and older had timely access to PCI facilities. The proportion varied widely across the country. Such information can inform the development of regionalized STEMI care models.

Comparison of distance measures in spatial analytical modeling for health service planning

BACKGROUND

Several methodological approaches have been used to estimate distance in health service research. In this study, focusing on cardiac catheterization services, Euclidean, Manhattan, and the less widely known Minkowski distance metrics are used to estimate distances from patient residence to hospital. Distance metrics typically produce less accurate estimates than actual measurements, but each metric provides a single model of travel over a given network. Therefore, distance metrics, unlike actual measurements, can be directly used in spatial analytical modeling. Euclidean distance is most often used, but unlikely the most appropriate metric. Minkowski distance is a more promising method. Distances estimated with each metric are contrasted with road distance and travel time measurements, and an optimized Minkowski distance is implemented in spatial analytical modeling.

METHODS

Road distance and travel time are calculated from the postal code of residence of each patient undergoing cardiac catheterization to the pertinent hospital. The Minkowski metric is optimized, to approximate travel time and road distance, respectively. Distance estimates and distance measurements are then compared using descriptive statistics and visual mapping methods. The optimized Minkowski metric is implemented, via the spatial weight matrix, in a spatial regression model identifying socio-economic factors significantly associated with cardiac catheterization.

RESULTS

The Minkowski coefficient that best approximates road distance is 1.54; 1.31 best approximates travel time. The latter is also a good predictor of road distance, thus providing the best single model of travel from patient's residence to hospital. The Euclidean metric and the optimal Minkowski metric are alternatively implemented in the regression model, and the results compared. The Minkowski method produces more reliable results than the traditional Euclidean metric.

CONCLUSION

Road distance and travel time measurements are the most accurate estimates, but cannot be directly implemented in spatial analytical modeling. Euclidean distance tends to underestimate road distance and travel time; Manhattan distance tends to overestimate both. The optimized Minkowski distance partially overcomes their shortcomings; it provides a single model of travel over the network. The method is flexible, suitable for analytical modeling, and more accurate than the traditional metrics; its use ultimately increases the reliability of spatial analytical models.

Visioning for secondary palliative care service hubs in rural communities: a qualitative case study from British Columbia's interior

Background

As the populations of many developed nations continue to age at rapid rates it is becoming increasingly important to enhance palliative care service delivery in order to meet anticipated demand. Rural areas face a number of challenges in doing this, and thus dedicated attention must be given to determining how to best enhance service delivery in ways that are sensitive to their particular needs. The purposes of this article are to determine the vision for establishing secondary palliative care service hubs (SPCH) in rural communities through undertaking a case study, and to ascertain the criteria that need to be considered when siting such hubs.

Methods

A rural region of British Columbia, Canada was selected for primary data collection, which took place over a five-month period in 2008. Formal and informal palliative care providers (n = 31) were interviewed. A purposeful recruitment strategy was used to maximize occupational and practice diversity. Interviews were conducted by phone using a semi-structured guide. Interviews were audio recorded and transcribed verbatim. Data were managed using NVivo8™ software and analyzed thematically, using investigator triangulation to strengthen interpretation.

Results

Four themes emerged from the dataset: (1) main SPCH features; (2) determining a location; (3) value-added outcomes; and (4) key considerations. It was found that participants generally supported implementing a SPCH in the rural region of focus. Several consistent messages emerged, including that: (1) SPCHs must create opportunities for two-way information exchange between specialists and generalists and communities; (2) SPCHs should diffuse information and ideas throughout the region, thus serving as a locus for education and a means of enhancing training opportunities; and (3) hubs need not be physical sites in the community (e.g., an office in a hospice or hospital), but may be virtual or take other forms based upon local needs.

Conclusion

Visioning innovation in the provision of palliative care service in rural communities can be enhanced by consultation with local providers. Interviews are a means of determining local concerns and priorities. There was widespread support for SPCH coupled with some uncertainty about means of implementation.

Assessing the suitability of host communities for secondary palliative care hubs: a location analysis model

An increased need for palliative care has been acknowledged world-wide. However, recent Canadian end-of-life care frameworks have largely failed to consider the unique challenges of delivery in rural and remote regions. In the Canadian province of British Columbia (BC), urban areas are well-served for specialized palliative care; however, rural and remote regions are not. This study presents a location analysis model designed to determine appropriate locations to allocate palliative care services. Secondary palliative care hubs (PCH) are introduced as an option for delivering these services in rural and remote regions. Results suggest that several BC communities may be appropriate locations for secondary PCHs. This model could be applied to the allocation of palliative care resources in other jurisdictions with similar rural and remote regions.

Tracking the polio virus down the Congo River: a case study on the use of Google Earth in public health planning and mapping

BACKGROUND

The use of GIS in public health is growing, a consequence of a rapidly evolving technology and increasing accessibility to a wider audience. Google Earth (GE) is becoming an important mapping infrastructure for public health. However, generating traditional public health maps for GE is still beyond the reach of most public health professionals. In this paper, we explain, through the example of polio eradication activities in the Democratic Republic of Congo, how we used GE Earth as a planning tool and we share the methods used to generate public health maps.

RESULTS

The use of GE improved field operations and resulted in better dispatch of vaccination teams and allocation of resources. It also allowed the creation of maps of high quality for advocacy, training and to help understand the spatiotemporal relationship between all the entities involved in the polio outbreak and response.

CONCLUSION

GE has the potential of making mapping available to a new set of public health users in developing countries. High quality and free satellite imagery, rich features including Keyhole Markup Language or image overlay provide a flexible but yet powerful platform that set it apart from traditional GIS tools and this power is still to be fully harnessed by public health professionals.
