Rural-urban differences in preventable hospitalizations among community-dwelling veterans with dementia

Dementia-focused programs in older adult centers and health care use among individuals with dementia

There is growing attention to community-based services for preventing adverse health care outcomes among people aging with dementia. We explored whether the availability of dementia-centered programming within older adult centers (ie, senior centers)-specifically, adult day services (ADS), social adult day centers (SADCs), memory cafes, and caregiver support-is associated with reduced hospitalization, emergency room use, and total Medicare costs for community-dwelling individuals ages 75 and older with Alzheimer's disease and related dementias (ADRD), and whether associations differ by the relative size of the local jurisdiction. We used a novel dataset that links Medicare claims data with data from an organizational census of municipally based Massachusetts older adult centers. Living in a community with an older adult center that facilitates access to ADS and/or SADCs was associated with reduced hospital utilization and costs among residents in smaller jurisdictions. We found no evidence for associations concerning memory cafes or support groups. These findings underscore the potential of older adult centers in curbing health care costs and acute care usage among individuals with ADRD, particularly in smaller communities with centers that provide access to ADS.

Impact of diabetes on mortality and hospitalization after dementia diagnosis: Health insurance claims data analysis

AIM

Japan faces a public health challenge of dementia, further complicated by the increasing complications from diabetes within its rapidly aging population. This study assesses the impact of diabetes on mortality and hospitalization among individuals aged ≥75 years with new dementia diagnoses.

METHODS

We analyzed administrative claims data in Japan from 73 324 individuals aged ≥75 years with dementia, of whom 17% had comorbid diabetes. Dementia and diabetes were identified from the International Classification of Diseases, Tenth Revision codes. We used Kaplan-Meier survival analysis, Cox proportional hazards analysis, and population attributable fractions (PAFs) to evaluate the impact on mortality and hospitalization after dementia diagnosis.

RESULTS

One-year mortality and 1-year hospitalization probabilities in individuals with dementia and diabetes (10.3% and 31.7%, respectively) were higher than those without diabetes (8.3% and 25.4%, respectively). The adjusted hazard ratios for individuals with diabetes, as compared to those without, were 1.126 (95% confidence interval [CI], 1.040-1.220) for mortality and 1.191 (95% CI, 1.140-1.245) for hospitalization. The PAFs from the comorbidity of dementia and diabetes were 2.2% for mortality and 3.1% for hospitalization. Subgroup analysis showed that the PAFs were highest in men aged 75-79 years and women aged 80-84 years for mortality and in individuals aged 75-79 for hospitalization.

CONCLUSION

During the early postdiagnosis period, comorbid diabetes increases mortality and hospitalization risks in older adults with dementia. The variation in disease burden across age groups underscores the need for age-specific health care strategies to manage comorbid diabetes in individuals with dementia.

Rural-urban differences in use of health services before and after dementia diagnosis: a retrospective cohort study

BACKGROUND

Rural-urban differences in health service use among persons with prevalent dementia are known. However, the extent of geographic differences in health service use over a long observation period, and prior to diagnosis, have not been sufficiently examined. The purpose of this study was to examine yearly rural-urban differences in the proportion of patients using health services, and the mean number of services, in the 5-year period before and 5-year period after a first diagnosis of dementia.

METHODS

This population-based retrospective cohort study used linked administrative health data from the Canadian province of Saskatchewan to investigate the use of five health services [family physician (FP), specialist physician, hospital admission, all-type prescription drug dispensations, and short-term institutional care admission] each year from April 2008 to March 2019. Persons with dementia included 2,024 adults aged 65 years and older diagnosed from 1 April 2013 to 31 March 2014 (617 rural; 1,407 urban). Matching was performed 1:1 to persons without dementia on age group, sex, rural versus urban residence, geographic region, and comorbidity. Differences between rural and urban persons within the dementia and control cohorts were separately identified using the Z-score test for proportions (p < 0.05) and independent samples t-test for means (p < 0.05).

RESULTS

Rural compared to urban persons with dementia had a lower average number of FP visits during 1-year and 2-year preindex and between 2-year and 4-year postindex (p < 0.05), a lower likelihood of at least one specialist visit and a lower average number of specialist visits during each year (p < 0.05), and a lower average number of all-type prescription drug dispensations for most of the 10-year study period (p < 0.05). Rural-urban differences were not observed in admission to hospital or short-term institutional care (p > 0.05 each year).

CONCLUSIONS

This study identified important geographic differences in physician services and all-type prescription drugs before and after dementia diagnosis. Health system planners and educators must determine how to use existing resources and technological advances to support care for rural persons living with dementia.

Social and spatial inequalities in healthcare use among people living with dementia in England (2002-2016)

OBJECTIVES

Healthcare services for people living with dementia (PLWD) are stretched, and government promises of increased funding remain undelivered. With the UK dementia population to surpass 1 million by 2024, and dementia care costs predicted to almost treble by 2040, it is essential we understand differences in healthcare use among PLWD. This study aimed to explore social and spatial variations in healthcare use among people diagnosed with dementia (2002-2016).

METHODS

Data were derived from Electronic Health Records of Clinical Practice Research Datalink GP patients in England (n = 142,302). To standardise healthcare contacts, rates of healthcare contacts per year were calculated for three primary (GP observations and medications) and three secondary healthcare types [Accident & Emergency (A&E) attendances and, emergency and elective hospital admissions]. Fully-adjusted generalised linear regression models were used to identify healthcare use variation by social and spatial groups. Twelve models were generated, one for each healthcare type in early- and late-onset populations separately.

RESULTS

This study highlights numerous social and spatial variations in healthcare use among PLWD. Among PLWD, several groups tended to have healthcare service use more closely associated with negative outcomes, including a greater likelihood of A&E attendances and emergency and elective hospital admissions. These groups include: men, people from White ethnicity groups and people from more deprived and rural areas.

CONCLUSIONS

Systemic and social measures are needed to reduce variations in healthcare use inequalities in PWLD. These include greater healthcare continuity, health checks and medicines reviews, culturally appropriate services, better and more accessible treatment and improved infrastructure.

Understanding Barriers Along the Patient Journey in Alzheimer's Disease Using Social Media Data

INTRODUCTION

We speculated that social media data from Alzheimer's disease (AD) stakeholders (patients, caregivers, and clinicians) could identify barriers along the patient journey in AD, and that insights gained may help devise strategies to remove barriers, and ultimately improve the patient journey.

METHODS

Our sample was drawn from a repository of social media posts extracted from 112 public sources between January 1998 and December 2021 using natural language processing text-mining algorithms. The patient journey was classified into three phases: (1) early signs/experiences (Early Signs); (2) screening/assessment/diagnosis (Screening); and (3) treatment/management (Treatment). In the Early Signs phase, issues/challenges derived from a conceptual AD identification framework (ADIF) were examined. In subsequent phases, behavioral/psychiatric challenges, access/barriers to health care, screening/diagnostic methods, and symptomatic treatments for AD were identified. Posts were classified by AD stakeholder type or disease stage, if possible.

RESULTS

We identified 225,977 AD patient journey-related social media posts. Anxiety was a predominant issue/challenge in all patient journey phases. In the Screening and Treatment phases combined, access/barriers to care were described in 16% of posts; unwillingness/resistance to seeking care was a major barrier (≥ 75% of access-related posts across all stakeholders). Commonly identified structural barriers (e.g., affordability/cost, geography/transportation/distance) were more common in patient/caregiver posts than clinician posts. Among Screening-related posts, imaging/scans were commonly mentioned by all stakeholders; biomarkers were more commonly mentioned by patients than clinicians. Treatment-related concerns were identified in 17% of stakeholder-specified posts that named pharmacological agents/classes for the symptomatic management of AD.

CONCLUSION

This descriptive analysis of out-of-clinic experiences reflected in AD social media posts found that unwillingness/resistance to seeking care was a key barrier, followed by structural barriers to health care, such as affordability/cost. Insights from the lived experiences of AD stakeholders are valuable and highlight the need to improve the patient journey in AD and ease patient and caregiver burden.

Rural and urban differences in quality of dementia care of persons with dementia and caregivers across all domains: a systematic review

BACKGROUND

There are challenges in healthcare service delivery in rural areas, and this may be especially true for persons with dementia, who have higher needs to access to the healthcare system, and may have difficulties to commute easily and safely to these services. There is a growing body of literature regarding geographical disparities, but there is no comprehensive systematic review of geographical differences in persons with dementia across all domains of care quality. Therefore, the objective of this study is to conduct a systematic review of the literature on rural and urban differences in quality of dementia care outcomes of persons with dementia across all quality-of-care domains.

METHODS

We performed a digital search in Ovid MEDLINE on July 16, 2019, updated on May 3, 2021, for French or English records. We selected studies that reported outcome from at least one domain of quality of dementia care (Access, Integration, Effective Care, Efficient Care, Population Health, Safety, and Patient-Centered) in both rural and urban persons with dementia or caregivers. We used rigorous, systematic methods for screening, selection, data extraction and we analyzed outcomes reported by at least two studies using vote counting and appraised the certainty of evidence. Finally, we explored sources of heterogeneity.

RESULTS

From the 38 included studies, we found differences in many dementia care domains. Rural persons with dementia had higher mortality rates (Population Health), lower visits to any physicians (Access), more hospitalizations but shorter stays (Integration), higher antipsychotic medications (Safety), lower use of home care services and higher use of nursing home (Patient-Centered Care) compared to urban persons with dementia.

CONCLUSIONS

This comprehensive portrait of rural-urban differences in dementia care highlights possible geographically based inequities and can be used by researchers and decision makers to guide development of more equitable dementia care policies.

Regional Health Disparities in Hypertension-Related Hospitalization of Hypertensive Patients: A Nationwide Population-Based Nested Case-Control Study

Objective: This study aims to explore regional health disparities in hypertension-related hospitalizations and confirm this difference according to the states of continuity of care (COC). Methods: We used the National Health Insurance Service National Sample Cohort data from 2002 to 2019. The dependent variable, hypertension-related hospitalization, included hospitalization for hypertensive diseases (I10-I13, I15), ischemic heart disease (I20-I25), and cerebrovascular disease (I60-I69). Nested case-control matching was performed according to age, sex, and income level. We compared hypertension-related hospitalization fractions in urban and rural areas by classifying them according to the state of COC and analyzed them using conditional logistic regression suitable for matched data. Results: The odds of hypertension-related hospitalization of hypertensive patients were higher in the rural areas than in the urban areas; however, as the COC increased, the difference decreased. There was no change in the results according to the COC observation period. Conclusion: To reduce regional health disparities, both the promotion of COC and the improvement of the quality of primary care must be achieved.

Use of high cost care among Veterans with comorbid mental illness and Alzheimer's Disease and related dementias

INTRODUCTION/OBJECTIVE

Alzheimer's Disease and Other Related Dementias (AD/ADRD) leads to frequent emergency department (ED) and inpatient use. Mental health symptoms among persons with AD/ADRD increases cognitive and functional disabilities and could contribute to these high rates of intensive health care use. The objective of this paper is to assess the relationship of mental illness on 12-month patterns in hospitalization and ED use among Veterans aged 65 and over with a new AD/ADRD diagnosis.

METHODS

We used an existing dataset of administrative electronic health record data of Veterans with AD/ADRD from the US Veterans Health Administration linked with Medicare claims data from 2011-2015. We use multivariable logistic regression to examine the association between no pre-existing mental illness, pre-existing mental illness (e.g., major depressive disorder, generalized anxiety disorder, or post-traumatic stress disorder), and pre-existing severe mental illness-or SMI-(e.g., bipolar disorder, major depressive disorder with psychosis, or schizophrenia) and 12- month ED and hospitalization use and readmissions among Veterans who had an initial hospitalization visit. We estimated predicted probabilities, differential effect, and associated 95% confidence intervals.

RESULTS

In our sample, 1.4% had SMI and 11% had non-SMI mental illness. The unadjusted percentage with inpatient and ED use was higher among Veterans with SMI (34% and 26%, respectively) and Veterans with non-SMI mental illness (20%, 16%) compared with Veterans without pre-existing mental illness (12%, 9%). Compared to individuals with no pre-existing mental illness, having a pre-existing mental illness (1.27 percentage points, 95% CI: 0.76, 1.78) and a pre-existing SMI (7.17 percentage points, 95% CI: 5.66, 8.69) were both associated with an increased likelihood of ED use. The same pattern was observed for any inpatient use (mental illness 2.18, 95% CI: 1.59, 2.77; SMI 9.91, 95% CI: 8.21, 11.61). Only pre-existing SMI was associated higher hospitalization readmission.

DISCUSSION

Pre-existing mental illness increases use of high cost, intensive health care and this association is higher of more severe mental health conditions. We also show that pre-existing mental illness exerts a unique influence, above and beyond other comorbidities, such as diabetes, on ED and inpatient visits. More needs to be done to increase recognition of the unique risks of this combination of health conditions and encourage strategies to address them. Developing, testing, and implementing comprehensive strategies that address the intersection of ADRD and mental illness is promising approach that requires more focused attention.

How Telemedicine Can Improve the Quality of Care for Patients with Alzheimer's Disease and Related Dementias? A Narrative Review

Background and Objectives: Dementia affects more than 55 million patients worldwide, with a significant societal, economic, and psychological impact. However, many patients with Alzheimer's disease (AD) and other related dementias have limited access to effective and individualized treatment. Care provision for dementia is often unequal, fragmented, and inefficient. The COVID-19 pandemic accelerated telemedicine use, which holds promising potential for addressing this important gap. In this narrative review, we aim to analyze and discuss how telemedicine can improve the quality of healthcare for AD and related dementias in a structured manner, based on the seven dimensions of healthcare quality defined by the World Health Organization (WHO), 2018: effectiveness, safety, people-centeredness, timeliness, equitability, integrated care, and efficiency. Materials and Methods: MEDLINE and Scopus databases were searched for peer-reviewed articles investigating the role of telemedicine in the quality of care for patients with dementia. A narrative synthesis was based on the seven WHO dimensions. Results: Most studies indicate that telemedicine is a valuable tool for AD and related dementias: it can improve effectiveness (better access to specialized care, accurate diagnosis, evidence-based treatment, avoidance of preventable hospitalizations), timeliness (reduction of waiting times and unnecessary transportation), patient-centeredness (personalized care for needs and values), safety (appropriate treatment, reduction of infection risk),integrated care (interdisciplinary approach through several dementia-related services), efficiency (mainly cost-effectiveness) and equitability (overcoming geographical barriers, cultural diversities). However, digital illiteracy, legal and organizational issues, as well as limited awareness, are significant potential barriers. Conclusions: Telemedicine may significantly improve all aspects of the quality of care for patients with dementia. However, future longitudinal studies with control groups including participants of a wide educational level spectrum will aid in our deeper understanding of the real impact of telemedicine in quality care for this population.

Alzheimer's Disease Mortality as a Function of Urbanization Level: 1999-2019

This study investigated Alzheimer's disease (AD) mortality trends by urbanization level and geographical location in the U.S. The CDC's WONDER database was used to investigate AD mortality from 1999-2019 stratified by urbanization level, census division, race, and sex. Data showed that while AD mortality increased across the U.S., rural areas, particularly in the South, had higher mortality compared to urban counterparts. AD mortality was higher among the female and White population. Data suggested that the urban-rural discrepancy is widening over time. Identifying health disparities underlying the urban-rural discrepancy in AD mortality is critical for allocating social and public health resources.

Identifying patterns of potentially preventable hospitalisations in people living with dementia

BACKGROUND

Older Australians make up 46% of all potentially preventable hospitalisations (PPHs) and people living with dementia are at significantly greater risk. While policy reforms aim to reduce PPHs, there is currently little evidence available on what drives this, especially for people living with dementia. This study examines patterns of PPHs in people living with dementia to inform service delivery and the development of evidence-based interventions.

METHODS

We used the Victorian Admitted Episodes Dataset from Victoria, Australia, to extract data for people aged 50 and over with a diagnosis of dementia between 2015 and 2016. Potentially avoidable admissions, known as ambulatory care sensitive conditions (ACSCs), were identified. The chi-square test was used to detect differences between admissions for ACSCs and non-ACSCs by demographic, geographical, and administrative factors. Predictors of ACSCs admissions were analysed using univariate and multiple logistic regression.

RESULTS

Of the 8156 hospital records, there were 3884 (48%) ACSCs admissions, of which admissions for urinary tract infections accounted for 31%, followed by diabetes complications (21%). Mean bed-days were 8.26 for non-ACSCs compared with 9.74 for ACSCs (p ≤ 0.001). There were no differences between admissions for ACSCs and non-ACSCs by sex, marital status, region (rural vs metro), and admission source (private accommodation vs residential facility). Culture and language predicted ASCS admission rates in the univariate regression analyses, with ACSC admission rates increasing by 20 and 29% if English was not the preferred language or if an interpreter was required, respectively. Results from the multiple regression analysis confirmed that language was a significant predictor of ACSC admission rates.

CONCLUSIONS

Improved primary health care may help to reduce the most common causes of PPHs for people living with dementia, particularly for those from culturally and linguistically diverse backgrounds.

Associations of GP practice characteristics with the rate of ambulatory care sensitive conditions in people living with dementia in England: an ecological analysis of routine data

BACKGROUND

Hospital admissions for Ambulatory Care Sensitive Conditions (ACSCs) are potentially avoidable. Dementia is one of the leading chronic conditions in terms of variability in ACSC admissions by general practice, as well as accounting for around a third of UK emergency admissions.

METHODS

Using Bayesian multilevel linear regression models, we examined the ecological association of organizational characteristics of general practices (ACSC n=7076, non-ACSC n=7046 units) and Clinical Commissioning Groups (CCG n=212 units) in relation to ACSC and non-ACSC admissions for people with dementia in England.

RESULTS

The rate of hospital admissions are variable between GP practices, with deprivation and being admitted from home as risk factors for admission for ACSC and non-ACSC admissions. The budget allocated by the CCG to mental health shows diverging effects for ACSC versus non-ACSC admissions, so it is likely there is some geographic variation.

CONCLUSIONS

A variety of factors that could explain avoidable admissions for PWD at the practice level were examined; most were equally predictive for avoidable and non-avoidable admissions. However, a high amount of variation found at the practice level, in conjunction with the diverging effects of the CCG mental health budget, implies that guidance may be applied inconsistently, or local services may have differences in referral criteria. This indicates there is potential scope for improvement.

Do Caregiving Factors Affect Hospitalization Risk Among Disabled Older Adults?

BACKGROUND/OBJECTIVES

Hospitalization is common among older adults with disability, many of whom receive help from a caregiver and have dementia. Our objective was to evaluate the association between caregiver factors and risk of hospitalization and whether associations differ by dementia status.

DESIGN

Longitudinal observational study.

SETTING

The 1999 and 2004 National Long-Term Care Survey and the 2011 and 2015 National Health and Aging Trends Study, linked caregiver surveys, and Medicare claims.

PARTICIPANTS

A total of 2,589 community-living Medicare fee-for-service beneficiaries, aged 65 years or older (mean age = 79 years; 63% women; 31% with dementia), with self-care or mobility disability and their primary family or unpaid caregiver.

MEASUREMENTS

Self-reported characteristics of older adults and their caregivers were assessed from older adult and caregiver survey interviews. Older adult hospitalization over the subsequent 12 months was identified in Medicare claims. Multivariable Cox proportional hazards models adjusted for older adult characteristics and were stratified by dementia status.

RESULTS

In this nationally representative cohort, 38% of older adults with disabilities were hospitalized over 12 months following interview. Increased hospitalization risk was associated with having a primary caregiver who helped with healthcare tasks (adjusted hazard ratio (aHR) = 1.22; 95% confidence interval (CI) = 1.05-1.40), reported physical strain (aHR = 1.21; 95% CI = 1.04-1.42), and provided more than 40 hours of care weekly (aHR = 1.26; 95% CI = 1.04-1.54 vs ≤20 hours). Having a caregiver who had helped for 4 years or longer (vs <1 year) was associated with 38% lower risk of hospitalization (aHR = 0.62; 95% CI = 0.49-0.79). Older adults with and without dementia had similar rates of hospitalization (39.5% vs 37.3%; P = .4), and caregiving factors were similarly associated with hospitalization regardless of older adults' dementia status.

CONCLUSION

Select caregiving characteristics are associated with hospitalization risk among older adults with disability. Hospitalization risk reduction strategies may benefit from understanding and addressing caregiving circumstances.

Factors Associated With Health Service Use Among Older Adults in a Mobile Veterans Program

The current retrospective, longitudinal study applied Andersen's Behavioral Model of Health Services Use to examine how demographic characteristics (age), available resources (e.g., a caregiver, the Mobile Veterans Program [MVP]) and health needs (e.g., cognitive and physical functioning, depressive symptoms) affect hospitalization and institutionalization outcomes among older adults using the MVP. Fifty-four Veterans (age 55 to 95) participating in the MVP for up to 2 years were examined using hierarchical linear modeling (HLM) and growth curve model. In the final HLM model, each 1-point increase in depressive symptoms was associated with 76% (p ≤ 0.05) greater risk of institutionalization and 40% (p ≤ 0.01) greater risk of hospitalization. Each 1-point increase in cognitive functioning was associated with 24% (p ≤ 0.05) lower risk of institutionalization. The relationship between caregiver burden and hospitalization was attenuated by frequency of MVP visits. Services focused on reducing depressive symptoms may influence health service use and reduce caregiver burden in this population. [Journal of Gerontological Nursing, 46(5), 15-22.].

Telemedicine: A valuable tool in neurodegenerative diseases

Purpose of Review

The prevalence of neurodegenerative diseases, such as Alzheimer's disease (AD) and Parkinson's disease (PD), is rising as the global population ages. Access to specialist care, which improves outcomes, is insufficient and disease-related disability makes in-person physician visits burdensome. Telehealth is one potential means for improving access to care. The purpose of this manuscript is to review recent publications on telemedicine in AD and PD.

Recent Findings

Telemedicine is feasible in AD and PD and acceptable to patients and their caregivers. Compared with in-person visits, telemedicine reduces visit-associated travel and time. Telemedicine can be used for rehabilitative therapies, to administer cognitive tests, and to support caregivers. Access to telemedicine results in changes in patient care including medication adjustments and referrals for therapies and supports.

Summary

The use of telemedicine in AD and PD stands to decrease burden on patients and increase access to specialty care. Barriers to the expansion of telemedicine care include lack of widespread broadband access, state licensure requirements, and inconsistent reimbursement. More outcomes-based prospective telemedicine studies are needed.

Hospitalisation rates and predictors in people with dementia: a systematic review and meta-analysis

BACKGROUND

Hospitalisation is often harmful for people with dementia and results in high societal costs, so avoidance of unnecessary admissions is a global priority. However, no intervention has yet reduced admissions of community-dwelling people with dementia. We therefore aimed to examine hospitalisation rates of people with dementia and whether these differ from people without dementia and to identify socio-demographic and clinical predictors of hospitalisation.

METHODS

We searched MEDLINE, Embase, and PsycINFO from inception to 9 May 2019. We included observational studies which (1) examined community-dwelling people with dementia of any age or dementia subtype, (2) diagnosed dementia using validated diagnostic criteria, and (3) examined all-cause general (i.e. non-psychiatric) hospital admissions. Two authors screened abstracts for inclusion and independently extracted data and assessed included studies for risk of bias. Three authors graded evidence strength using Cochrane's GRADE approach, including assessing for evidence of publication bias using Begg's test. We used random effects meta-analysis to pool estimates for hospitalisation risk in people with and without dementia.

RESULTS

We included 34 studies of 277,432 people with dementia: 17 from the USA, 15 from Europe, and 2 from Asia. The pooled relative risk of hospitalisation for people with dementia compared to those without was 1.42 (95% confidence interval 1.21, 1.66) in studies adjusted for age, sex, and physical comorbidity. Hospitalisation rates in people with dementia were between 0.37 and 1.26/person-year in high-quality studies. There was strong evidence that admission is associated with older age, and moderately strong evidence that multimorbidity, polypharmacy, and lower functional ability are associated with admission. There was strong evidence that dementia severity alone is not associated.

CONCLUSIONS

People with dementia are more frequently admitted to hospital than those without dementia, independent of physical comorbidities. Future interventions to reduce unnecessary hospitalisations should target potentially modifiable factors, such as polypharmacy and functional ability, in high-risk populations.

Difference in frequency and outcome of geriatric emergency department utilization between urban and rural areas

BACKGROUND

Elderly people are susceptible to develop multiple chronic diseases and are thus likely to utilize the emergency department (ED). Access to health care and health outcomes may differ between rural and urban areas. This study aims to compare the frequency and outcome of geriatric ED utilization between urban and rural areas.

METHODS

This population-based study obtained information from the health insurance database. The frequency and outcome of ED utilization in 2013 were compared among people aged ≥65 years living in urban and rural areas. The independent effect of various characteristics on the frequency and outcome of ED utilization was evaluated using multivariate logistic regression analysis.

RESULTS

Of the 6695 people living in urban areas, 1879 (28.07%) utilized the ED and accounted for 3859 ED visits. Meanwhile, 908 (29.75%) of the 3052 people living in rural areas utilized the ED and accounted for 1820 ED visits. No difference in the prevalence of ED utilization was found between the urban and rural areas. Urbanization did not affect the risk of frequent ED utilization among ED users. People living in rural areas had an increased risk of ED visits with a high acuity (adjusted odds ratio: 1.40, 95% CI: 1.12-1.75). Urbanization did not affect the risk of hospitalization or immediate death after ED visits.

CONCLUSION

The frequency of ED utilization showed no urban-rural difference. Elderly people living in rural areas had an increased risk of visiting the ED with a high acuity.

Influences on the access to and use of formal community care by people with dementia and their informal caregivers: a scoping review

BACKGROUND

The literature describes the obstacles to sufficient care faced by people with dementia and their informal caregivers. Although factors influencing access and utilisation are frequently studied, the body of knowledge lacks an overview of aspects related to influence. The frequently used Behavioural Model of Health Care Use (BM) could be used to structure and explain these aspects. An adaptation of the BM emphasises psychosocial influences and appears to enrich the understanding of the use of long-term care for dementia.

METHODS

We conducted a scoping review with the aim of providing an overview of the aspects influencing the access to and utilisation of formal community care in dementia. Our search covered the PubMed, CINAHL, Social Science Citation Index and PsychInfo databases, as well as grey literature. Two researchers assessed the full texts for eligibility. A data extraction form was developed and tested. We analysed the main topics investigated by the studies and mapped and described the investigated psychosocial aspects according to the BM after narratively summarising the findings. We used the Mixed Method Appraisal Tool (MMAT) to critically appraise the included studies.

RESULTS

A total of 94 studies were included: n = 55 with quantitative designs, 35 with qualitative designs and four with mixed methods. The studies investigated different services, mainly focusing on health care services. One third of the studies provided information regarding the severity of dementia. The most frequently investigated main topics were ethnicity and attitudes towards services. Psychosocial aspects were frequently investigated, although few studies considered the perspectives of people with dementia. Approximately half of the studies reported a theoretical framework. The adapted BM facilitated the structuring and description of psychosocial aspects. However, this instrument did not address topics beyond the scope of psychosocial aspects, such as sociodemographic characteristics.

CONCLUSIONS

The access to and utilisation of formal community care for dementia can only be partly explained by individual influencing aspects. Therefore, a theoretical framework would likely help to describe this complex subject. Our findings indicate that the psychosocial categories of the adapted BM enriched the original BM, and that people with dementia should more often be included in healthcare service research to ensure a better understanding of the barriers to accessing formal community care.

Rural Dementia Caregivers and Technology: What Is the Evidence?

Caregivers of adults with dementia often experience burden and depression as a result of their intensive caregiving activities. Dementia caregivers in rural communities experience additional barriers of large distances from health care providers and/or limited numbers of health care providers, which may further exacerbate burden. Technology has been identified as a platform for reducing dementia caregiver burden and stress, although the extent to which technologically based interventions have been tested with rural dementia caregivers is unknown. The current study involved a systematic review of technologically based interventions to assess the geography of sample populations, scope of interventions, and study outcomes. Of 8,348 articles identified and screened, 30 articles met eligibility guidelines. The current review found that few studies identified their sample population as living in rural communities. In addition, studies were more likely to report improved psychosocial outcomes of intervention groups, with few reporting positive effects on caregiving skills/self-efficacy. Implications for future research are discussed. [Res Gerontol Nurs. 2018; 11(4):216-224.].

Associations between structures and resources of primary care at the district level and health outcomes: a case study of diabetes mellitus care in Thailand

Background

The structural factors of primary care potentially influence its performance and quality. This study investigated the association between structural factors, including available primary care resources and health outcomes, by using diabetes-related ambulatory care sensitive conditions hospitalizations under the Universal Coverage Scheme in Thailand.

Methods

A 2-year panel study used secondary data compiled at the district level. Administrative claim data from 838 districts during the 2014–2015 fiscal years from the National Health Security Office were used to analyze overall diabetes mellitus (DM) hospitalizations and its three subgroups: hospitalizations for uncontrolled diabetes, short-term complications, and long-term complications. Primary care structural data were obtained from the Ministry of Public Health. Generalized estimating equations were used to estimate the influence of structural factors on the age-standardized DM hospitalization ratio.

Results

A higher overall DM and uncontrolled diabetes hospitalization ratio was related to an increasing concentration of outpatient utilization (using the Herfindahl–Hirschman Index) (overall DM; beta [standard error, SE]=0.003 [0.001], 95% CI 0.000, 0.006) and decreasing physician density and bed supply (overall DM; beta [SE]=−1.350 [0.674], 95% CI −2.671, −0.028), beta [SE]=−0.023 [0.011], 95% CI −0.045, −0.001, respectively). Hospitalizations for short-term complications increased with a decrease in health care facility density, whereas hospitalizations for long-term complications increased as that density increased. Rurality was strongly associated with higher hospitalization ratios for all DM hospitalizations except short-term complications.

Conclusions

This study identified structural factors associated with health outcomes, many of which can be changed through reorganization at the district level.

Hospital admissions 2000-2014: A retrospective analysis of 288 096 events in patients with dementia

INTRODUCTION

Dementia is a leading cause of disability worldwide. It is associated with an increased risk of hospitalization, imposing a significant burden on healthcare systems. The evidence on the long-term evolution of this issue and broadly on healthcare systems is currently limited. This study aims to describe the hospitalizations of people who received a diagnosis of dementia admitted to public general hospitals in a western European country with universal health coverage, over more than a decade.

METHODS

This retrospective observational study analyzed all inpatient episodes from 2000 to 2014 with a primary or secondary diagnosis of dementia using a national hospitalization database from mainland Portuguese public hospitals.

RESULTS

A total of 288 096 hospital admissions were registered. Hospitalization rates increased 4.7 times throughout the study period. Pneumonia and urinary tract infections were the most frequent main diagnoses, while dementia itself was the cause of admission in a minority (6.8%) of cases. Cerebrovascular disease, diabetes without chronic complications, and congestive heart failure were the most prevalent comorbidities; 5.9% of patients with dementia admitted to hospital underwent a surgical procedure, orthopedic surgeries being the most frequent. The median length of hospital stay was 8.0 days, and in-hospital mortality rate was 16.1%.

CONCLUSIONS

Dementia patients represent a significant amount of hospital admissions. Most leading causes of hospital admissions are preventable if timely diagnosed and could be effectively managed in the outpatient setting. These findings may be useful for healthcare resource planning and allocation. Further research should drive evidence-based reorganization of health care systems.

Rural Disparities in Alzheimer's Disease-Related Community Pharmacy Care in the United States

PURPOSE

To examine the relationship between area population density and community pharmacy-based Alzheimer's Disease (AD)-related services: pharmacists' medication knowledge and counseling, immunizations, and in-stock cognitive enhancers in 3 predominantly rural regions of the United States.

METHODS

A standardized interview was administered by telephone to a 100% sample of community pharmacies in 3 areas: Northern California/Southern Oregon (n = 206), North and South Dakota (n = 278), and West Virginia (n = 420). Key study outcomes included: pharmacists' medication knowledge, availability of immunization services, and cognitive enhancers in stock. Respondents were classified by population density (persons/mi² ) by pharmacy location to evaluate the relationship between rurality and AD-related pharmacy services. Chi-squared and logistic regression analyses were performed using Stata 10.1.

FINDINGS

Pharmacies in more rural areas (50.1-100.0, 25.1-50.0, and ≤25.0 persons/mi² ) were about 50% less likely to offer immunizations (95% CI: 0.32-0.91; 0.32-0.76; 0.28-0.80, respectively) compared to the least rural areas (>100.0 persons/mi² ). Compared to the least rural areas, pharmacists in the most rural areas (≤25.0 persons/mi² ) were less likely to name ≥2 gastrointestinal adverse effects of donepezil (OR = 0.50, 95% CI: 0.31-0.82) or have memantine XR 28 mg (OR = 0.61, 95% CI: 0.41-0.89) and other surveyed medications (OR = 0.57, 95% CI: 0.39-0.82) in stock.

CONCLUSIONS

We found disparities in AD-related services in community pharmacies located in more rural counties, wherein individuals with AD and their caregivers may face barriers to obtaining quality pharmaceutical care. There is a need to strengthen pharmacists' knowledge and improve pharmacy services to reduce disparities.

Financial and Health Barriers and Caregiving-Related Difficulties Among Rural and Urban Caregivers

PURPOSE

To assess whether financial or health-related barriers were more common among rural caregivers and whether rural caregivers experienced more caregiving-related difficulties than their urban peers.

METHODS

We used data from 7,436 respondents to the Caregiver Module in 10 states from the 2011-2013 Behavioral Risk Factor Surveillance System. Respondents were classified as caregivers if they reported providing care to a family member or friend because of a long-term illness or disability. We classified respondents as living in a rural area if they lived outside of a Metropolitan Statistical Area (MSA). We defined a financial barrier as having an annual household income <$25,000 or not being able see a doctor when needed in the past year because of cost. We defined a health barrier as having multiple chronic health conditions, a disability, or fair or poor self-rated health.

FINDINGS

Rural caregivers more frequently had financial barriers than urban caregivers (38.1% vs 31.0%, P = .0001), but the prevalence of health barriers was similar (43.3% vs 40.6%, P = .18). After adjusting for demographic differences, financial barriers remained more common among rural caregivers. Rural caregivers were less likely than their urban peers to report that caregiving created any difficulty in both unadjusted and adjusted models (adjusted prevalence ratio = 0.90; P < .001).

CONCLUSIONS

Informal caregivers, particularly in rural areas, face financial barriers. Rural caregivers were less likely than urban caregivers to report caregiving-related difficulties. Rural caregivers' coping strategies or skills in identifying informal supports may explain this difference, but additional research is needed to explore this hypothesis.

Creation of an Interprofessional Teledementia Clinic for Rural Veterans: Preliminary Data

The teledementia clinic is a new model of care that expands the reach of specialized geriatric and dementia care using clinical video telehealth (CVT) to rural veterans, who frequently lack access to specialty care. The clinic is a Veterans Affairs (VA) Geriatric Research, Education, and Clinical Center clinical demonstration project. It is located in the Pittsburgh VA Healthcare System tertiary referral hospital and serves veterans in affiliated rural community-based outpatient clinics (CBOCs). Rural CBOC primary care providers refer clinic patients, or referral is according to previous cognitive impairment diagnosis in a VAPHS geriatric clinic. Patients undergo interprofessional dementia assessment by a geriatrician, geropsychologist, geriatric psychiatrist or neurologist, and social worker using CVT technology. Metrics for clinic evaluation included rural patients served and savings in travel time, distance, and costs. Assessments collected depended upon individual presentation and included cognitive tests, geriatric depression scales, functional assessment, and the Zarit Burden Interview. A patient satisfaction survey was created and administered. In the first year, 95 individuals were served in 156 clinic visits and 251 interprofessional provider encounters. Of patients served, 61 lived in rural ZIP codes, 72 were diagnosed with dementia, 19 were diagnosed with mild cognitive impairment, and four were found to have primarily psychiatric diagnoses rather than cognitive impairment. The average Functional Assessment Staging of Alzheimer's Disease Scale score was 4.3 ± 1.3. This clinic model demonstrates that CVT technology is a feasible means of providing interprofessional dementia evaluations and follow-up to rural presidents.

Have Racial Disparities in Ambulatory Care Sensitive Admissions Abated Over Time?

BACKGROUND

Racial disparities in access to care and access to high-quality care have been persistent over many decades. They have been documented in all areas of health care, including ambulatory care. Policy initiatives have been implemented to address disparities and close the gaps in care that minorities face. Less is known about the effectiveness of these polices.

OBJECTIVES

To evaluate whether disparities in quality of ambulatory care have abated during the decade of 2000 by answering 2 questions: (1) were there differences in ambulatory care sensitive hospital admissions rates by race?; (2) have these differences been declining over time?

RESEARCH DESIGN

Multivariable linear regressions with fixed county effects and robust SEs of longitudinal panel data.

SUBJECTS

A total of 4,032,322 discharges in 172 counties in 6 states during 2003-2009.

MEASURES

Prevention Quality Indicators (PQIs) developed by the Agency for Healthcare Research and Quality, by county, and race calculated from the Healthcare Cost and Utilization Project dataset.

RESULTS

In 2003 the overall PQI admission rates were higher for African Americans (around 16.5/1000) than for whites (around 15/1000). By 2009, the overall and the chronic PQI admission rates declined significantly (P<0.01) for whites. They either did not decline or increased for African Americans. Acute PQI rates declined significantly for whites and remained stable for African Americans.

CONCLUSIONS

Policies addressing persisting racial disparities in quality of ambulatory care for African Americans should focus on the chronic PQIs. In addition, efforts should be made to improve data quality for race and ethnicity information on hospital discharge data to enable informed policy evaluation and planning.

Spatiotemporal Discordance in Five Common Measures of Rurality for US Counties and Applications for Health Disparities Research in Older Adults

Introduction

Rural populations face numerous barriers to health, including poorer health care infrastructure, access to care, and other sociodemographic factors largely associated with rurality. Multiple measures of rurality used in the biomedical and public health literature can help assess rural–urban health disparities and may impact the observed associations between rurality and health. Furthermore, understanding what makes a place truly “rural” versus “urban” may vary from region to region in the US.

Purpose

The objectives of this study are to compare and contrast five common measures of rurality and determine how well-correlated these measures are at the national, regional, and divisional level, as well as to assess patterns in the correlations between the prevalence of obesity in the population aged 60+ and each of the five measures of rurality at the regional and divisional level.

Methods

Five measures of rurality were abstracted from the US Census and US Department of Agriculture (USDA) to characterize US counties. Obesity data in the population aged 60+ were abstracted from the Behavioral Risk Factor Surveillance System (BRFSS). Spearman’s rank correlations were used to quantify the associations among the five rurality measurements at the national, regional, and divisional level, as defined by the US Census Bureau. Geographic information systems were used to visually illustrate temporal, spatial, and regional variability.

Results

Overall, Spearman’s rank correlations among the five measures ranged from 0.521 (percent urban–urban influence code) to 0.917 (rural–urban continuum code–urban influence code). Notable discrepancies existed in these associations by Census region and by division. The associations between measures of rurality and obesity in the 60+ population varied by rurality measure used and by region.

Conclusion

This study is among the first to systematically assess the spatial, temporal, and regional differences and similarities among five commonly used measures of rurality in the US. There are important, quantifiable distinctions in defining what it means to be a rural county depending on both the geographic region and the measurement used. These findings highlight the importance of developing and selecting an appropriate rurality metric in health research.

Rural-Urban Differences in Alzheimer's Disease and Related Disorders Diagnostic Prevalence in Kentucky and West Virginia

PURPOSE

Older adults living in rural areas may face barriers to obtaining a diagnosis of Alzheimer's disease and related disorders (ADRD). We sought to examine rural-urban differences in prevalence of ADRD among Medicare beneficiaries in Kentucky and West Virginia, 2 contiguous, geographically similar states with large rural areas and aged populations.

METHODS

We used Centers for Medicare and Medicaid Services Public Use Files data from 2007 to 2013 to assess prevalence of ADRD at the county level among all Medicare beneficiaries in each state. Rural-Urban Continuum Codes were used to classify counties as rural or urban. We used Poisson regression to estimate unadjusted and adjusted prevalence ratios. Primary analyses focused on 2013 data and were repeated for 2007 to 2012. This study was completely ecologic.

FINDINGS

After adjusting for state, average beneficiary age, percent of female beneficiaries, percent of beneficiaries eligible for Medicaid in each county, Central Appalachian county, percent of age-eligible residents enrolled in Medicare, and percent of residents under age 65 enrolled in Medicare in our adjusted models, we found that 2013 ADRD diagnostic prevalence was 11% lower in rural counties (95% CI: 9%-13%).

CONCLUSIONS

Medicare beneficiaries in rural counties in Kentucky and West Virginia may be underdiagnosed with respect to ADRD. However, due to the ecologic design, and evidence of a younger, more heavily male beneficiary population in some rural areas, further studies using individual-level data are needed to confirm the results.

Rural access to clinical pharmacy services

OBJECTIVES

To examine the impact of rural residence and primary care site on use of clinical pharmacy services (CPS) and to describe the use of clinical telepharmacy within the Veterans Health Administration (VHA) health care system.

METHODS

Using 2011 national VHA data, the frequency of patients with CPS encounters was compared across patient residence (urban or rural) and principal site of primary care (medical center, urban clinic, or rural clinic). The likelihood of CPS utilization was estimated with random effects logistic regression. Individual service types (e.g., anticoagulation clinics) and delivery modes (e.g., telehealth) were also examined.

RESULTS

Of 3,040,635 patients, 711,348 (23.4%) received CPS. Service use varied by patient residence (urban: 24.9%; rural: 19.7%) and principal site of primary care (medical center: 25.9%; urban clinic: 22.5%; rural clinic: 17.6%). However, in adjusted analyses, urban-rural differences were explained primarily by primary care site and less so by patient residence. Similar findings were observed for individual CPS types. Telehealth encounters were common, accounting for nearly one-half of patients receiving CPS. Video telehealth was infrequent (<0.2%), but more common among patients of rural clinics than those receiving CPS at medical centers (odds ratio [OR] = 9.7; 95% CI 9.0-10.5).

CONCLUSION

We identified a potential disparity between rural and urban patients' access to CPS, which was largely explained by greater reliance on community clinics for primary care than on medical centers. Future research is needed to determine if this disparity will be alleviated by emerging organizational changes, including expanding telehealth capacity and integrating pharmacists into primary care teams, and whether lessons learned at VHA translate to other settings.

The association between managed care enrollments and potentially preventable hospitalization among adult Medicaid recipients in Florida

Background

The intent of adopting managed care plans is to improve access to health care services while containing costs. To date, there have been a number of studies that examine the relationship between managed care and access to health care. However, the results from previous studies have been inconsistent. Specifically, previous studies did not demonstrate a clear benefit of Medicaid managed care. In this study we have examine whether Medicaid managed care is associated with the probabilities of preventable hospitalizations. This study also analyzes the spillover effect of Medicaid managed care into Medicaid patients in traditional FFS plans and the interaction effects of other patient- and county-level variables on preventable hospitalizations.

Methods

The study included 254,321 Medicaid patients who were admitted to short-term general hospital in the 67 counties in Florida. Using 2008 hospital inpatient discharge data for working-age adult Medicaid enrollees (18-64 years) in Florida, we conduct multivariate logistic regression analyses to identify possible factors associated with preventable hospitalizations. The first model includes patient- and county-level variables. Then, we add interaction terms between Medicaid HMO and other variables such as race, rurality, market-level factors, and resource for primary care.

Results

The results show that Medicaid HMO patients are more likely to be hospitalized for ambulatory care sensitive conditions (ACSCs) (OR = 1.30; CI = 1.21, 1.40). We also find that market structure (i.e., competition) is significantly associated with preventable hospitalizations. However, our study does not support that there are spillover effects of Medicaid managed care on preventable hospitalizations for other Medicaid recipients. We find that interactions between Medicaid managed care and race, rurality and market structure are significant.

Conclusions

The results of our study show that the Medicaid managed care program in Florida was associated with an increase in potentially preventable hospitalizations for Medicaid enrollees. The results suggest that lower capitation rate has been associated with a greater likelihood of preventable hospitalizations for Medicaid managed care patients. Our findings also indicate that increased competition in the Medicaid managed care market has no clear benefit in Medicaid managed care patients.

Predictors of Inpatient Utilization among Veterans with Dementia

Dementia is prevalent and costly, yet the predictors of inpatient hospitalization are not well understood. Logistic and negative binomial regressions were used to identify predictors of inpatient hospital utilization and the frequency of inpatient hospital utilization, respectively, among veterans. Variables significant at the P < 0.15 level were subsequently analyzed in a multivariate regression. This study of veterans with a diagnosis of dementia (n = 296) and their caregivers found marital status to predict hospitalization in the multivariate logistic model (B = 0.493, P = 0.029) and personal-care dependency to predict hospitalization and readmission in the multivariate logistic model and the multivariate negative binomial model (B = 1.048, P = 0.007, B = 0.040, and P = 0.035, resp.). Persons with dementia with personal-care dependency and spousal caregivers have more inpatient admissions; appropriate care environments should receive special care to reduce hospitalization. This study was part of a larger clinical trial; this trial is registered with ClinicalTrials.gov NCT00291161.

Urban-rural disparity of generics prescription in Taiwan: the example of dihydropyridine derivatives

The aim of the current study was to investigate the urban-rural disparity of prescribing generics, which were usually cheaper than branded drugs, within the universal health insurance system in Taiwan. Data sources were the cohort datasets of National Health Insurance Research Database with claims data in 2010. The generic prescribing ratios of dihydropyridine (DHP) derivatives (the proportion of DHP prescribed as generics to all prescribed DHP) of medical facilities were examined against the urbanization levels of the clinic location. Among the total 21,606,914 defined daily doses of DHP, 35.7% belonged to generics. The aggregate generic prescribing ratio rose from 6.7% at academic medical centers to 15.3% at regional hospitals, 29.4% at community hospital, and 66.1% at physician clinics. Among physician clinics, the generic prescribing ratio in urban areas was 63.9 ± 41.0% (mean ± standard deviation), lower than that in suburban (69.6 ± 38.7%) and in rural (74.1% ± 35.3%). After adjusting the related factors in the linear regression model, generic prescribing ratios of suburban and rural clinics were significantly higher than those of urban clinics (β = 0.043 and 0.077; P = 0.024 and 0.008, resp.). The generic prescribing ratio of the most popular antihypertensive agents at a clinic was reversely associated with the urbanization level.

Caregiver psychological health and hospitalization characteristics of older adult care recipients: an integrative review of U.S. studies

This integrative review involved studies conducted in the United States that assessed hospitalizations of older adults receiving family care and the psychological health of their family caregivers. The primary objectives were to (a) summarize findings between caregiver psychological health and older care recipient hospitalizations, and (b) describe how caregiver psychological health has been measured with regard to older care recipient hospitalizations. Online databases were searched for articles assessing caregiver psychological health (e.g., burden, strain, depressive or anxious symptoms) and older care recipient hospitalizations in the United States. According to the findings, few studies in the United States have assessed hospitalization characteristics of older care recipients and the psychological health of their family caregivers. All analyses incorporated a measure of depression; however, the measurement of other psychological health constructs (e.g., anxious symptoms, perceived burden) was limited or absent. Findings note the potential importance of focusing on readmission rates in light of caregiver psychological health. Findings also note the benefit of caregiver emotional and instrumental support toward reducing hospitalizations among older adults receiving family care.

A comparison of mental health, substance use, and sexual risk behaviors between rural and non-rural transgender persons

The aim of this study was to compare the mental health, substance use, and sexual risk behaviors of rural and non-rural transgender persons. Online banner advertisements were used to recruit 1,229 self-identified rural and non-rural transgender adults (18+ years) residing in the United States. Primary findings include significant differences in mental health between rural and non-rural transmen; relatively low levels of binge drinking across groups, although high levels of marijuana use; and high levels of unprotected sex among transwomen. The results confirm that mental and physical health services for transgender persons residing in rural areas are urgently needed.

The impact of living in rural and urban areas: vitamin D and medical costs in veterans

PURPOSE

Living in a rural region is associated with significant health disparities and increased medical costs. Vitamin D deficiency, which is increasingly common, is also associated with many adverse health outcomes. The purpose of this study was to determine whether rural-urban residence status of veterans was related to vitamin D levels, and to determine if this factor also influenced medical costs/service utilization. Additionally explored was whether vitamin D differences accounted for part of the association between area of residence and medical costs/service utilization.

METHODS

Medical records of 9,396 veterans from 6 Veterans Administration Medical Centers were reviewed for variables of interest including county of residence, vitamin D level, medical costs and service utilization, and background variables. Rurality status was classified as large metropolitan, urban, and rural.

FINDINGS

The 3 rurality status groups differed significantly in vitamin D levels, with the highest levels observed for urban residents, followed by rural residents, and the lowest for large metro residents. Compared with urban residents, large metro residents were 49% more likely, while rural residents were 20% more likely, to be vitamin D deficient. Both rural and large metro residents had higher medical costs, and they were significantly more likely to be hospitalized. Vitamin D levels explained a statistically significant amount of the relationship between rurality status and medical costs/service utilization.

CONCLUSIONS

Vitamin D deficiency may be an additional health disparity experienced by both rural and inner-city veterans, and patients residing in these locations should be considered at increased risk for deficiency and routinely tested.

Comprehensive determinants of health service utilisation for mental health reasons in a Canadian catchment area

INTRODUCTION

This study sought to identify factors associated with health service utilisation by individuals with mental disorders in a Canadian catchment area.

METHODS

To be included in the study, participants had to be aged between 15 and 65 and reside in the study location. Data was collected randomly from June to December 2009 by specially trained interviewers. A comprehensive set of variables (including geospatial factors) was studied using the Andersen's behavioural health service model. Univariate, bivariate, and multivariate analyses were carried out.

RESULTS

Among 406 individuals diagnosed with mental disorders, 212 reported using a mental health service at least once in the 12 months preceding the interviews. Emotional problems and a history of violence victimisation were most strongly associated with such utilisation. Participants who were middle-aged or deemed their mental health to be poor were also more likely to seek mental healthcare. Individuals living in neighbourhoods where rental accommodations were the norm used significantly fewer health services than individuals residing in neighbourhoods where homeownership was preponderant; males were also less likely to use services than females.

CONCLUSIONS

Our study broke new ground by uncovering the impact of longstanding violence victimisation, and the proportion of homeownership on mental health service utilisation among this population. It also confirmed the prominence of some variables (gender, age, emotional problems and self-perceived mental health) as key enabling variables of health-seeking. There should be better promotion of strategies designed to change the attitudes of males and youths and to deal with violence victimisation. There is also a need for initiatives that are targeted to neighbourhoods where there is more rental housing.

Dual Medicare and Veteran Health Administration use and ambulatory care sensitive hospitalizations

OBJECTIVE

The objective of the study is to examine the association between ambulatory care sensitive hospitalizations (ACSH) and dual Medicare/Veteran Health Administration use.

PARTICIPANTS

A nationally representative sample of Medicare beneficiaries, who participated in the Medicare Current Beneficiary Survey (MCBS).

DESIGN/MEASUREMENTS

Cross-sectional analyses (N = 44,988) of linked fee-for-service Medicare claims and survey data from multiple years of the MCBS (2001-2005). Any ACSH and specific types of ACSH were measured using the list of prevention quality indicators developed by the Agency for Healthcare Research and Quality. Among veterans, dual Medicare/VHA use was defined as having inpatient or outpatient visits paid by VHA and consisted of three categories: 1) predominant-VHA use; 2) some VHA use and no VHA use. Unadjusted group differences in any ACSH were tested using chi-square tests. Logistic regressions were used to analyze the association between dual Medicare/VHA use and ACSH after controlling for demographic, socio-economic status, health status, functional status, smoking status and obesity. All analyses accounted for the complex design of the MCBS.

RESULTS

Among inpatient users, 10.1% had ACSH events for acute conditions and 15.8% for chronic conditions. Among all survey respondents, 5% had any ACSH event. Among predominant-VHA users the rate was 4.9% and among veterans with some VHA use it was 3.7%. In bivariate and multivariate analyses, dual Medicare/VHA use was not significantly associated with any ACSH.

CONCLUSION

In a representative sample of Medicare beneficiaries, despite low income and health status, veterans with dual Medicare/VHA use were as likely as veterans without dual use to have any ACSH, perhaps due to expanded healthcare access and emphasis on primary care in the VHA system.
