Chronic care costs in managed care

Sociodemographic Differences in the Impacts of Video-Enabled Tablets on Psychotherapy Usage Among Veterans

OBJECTIVE

To examine potential health disparities due to a broad reliance on telehealth during the COVID-19 pandemic, the authors studied the impact of video-enabled tablets provided by the U.S. Department of Veterans Affairs (VA) on psychotherapy usage among rural versus urban, Black versus White, and female versus male veterans.

METHODS

Psychotherapy usage trends before and after onset of the COVID-19 pandemic were examined among veterans with at least one mental health visit in 2019 (63,764 tablet recipients and 1,414,636 nonrecipients). Adjusted difference-in-differences and event study analyses were conducted to compare psychotherapy usage among tablet recipients and nonrecipients (March 15, 2020-December 31, 2021) 10 months before and after tablet issuance. Analyses were stratified by rurality, sex, and race.

RESULTS

Adjusted analyses demonstrated that tablet receipt was associated with increases in psychotherapy visit frequency in every patient group studied (rural, 27.4%; urban, 24.6%; women, 30.5%; men, 24.4%; Black, 20.8%; White, 28.1%), compared with visits before tablet receipt. Compared with men, women had statistically significant tablet-associated psychotherapy visit increases (video visits, 1.2 per year; all modalities, 1.0 per year).

CONCLUSIONS

VA-issued tablets led to increased psychotherapy usage for all groups examined, with similar increases found for rural versus urban and Black versus White veterans and higher increases for women versus men. Eliminating barriers to Internet access or device ownership may improve mental health care access among underserved or historically disadvantaged populations. VA's tablet program offers insights to inform policy makers' and health systems' efforts to bridge the digital divide.

Multimorbidity healthcare expenditure in Belgium: a 4-year analysis (COMORB study)

BACKGROUND

The complex management of health needs in multimorbid patients, alongside limited cost data, presents challenges in developing cost-effective patient-care pathways. We estimated the costs of managing 171 dyads and 969 triads in Belgium, taking into account the influence of morbidity interactions on costs.

METHODS

We followed a retrospective longitudinal study design, using the linked Belgian Health Interview Survey 2018 and the administrative claim database 2017-2020 hosted by the Intermutualistic Agency. We included people aged 15 and older, who had complete profiles (N = 9753). Applying a system costing perspective, the average annual direct cost per person per dyad/triad was presented in 2022 Euro and comprised mainly direct medical costs. We developed mixed models to analyse the impact of single chronic conditions, dyads and triads on healthcare costs, considering two-/three-way interactions within dyads/triads, key cost determinants and clustering at the household level.

RESULTS

People with multimorbidity constituted nearly half of the study population and their total healthcare cost constituted around three quarters of the healthcare cost of the study population. The most common dyad, arthropathies + dorsopathies, with a 14% prevalence rate, accounted for 11% of the total national health expenditure. The most frequent triad, arthropathies + dorsopathies + hypertension, with a 5% prevalence rate, contributed 5%. The average annual direct costs per person with dyad and triad were €3515 (95% CI 3093-3937) and €4592 (95% CI 3920-5264), respectively. Dyads and triads associated with cancer, diabetes, chronic fatigue, and genitourinary problems incurred the highest costs. In most cases, the cost associated with multimorbidity was lower or not substantially different from the combined cost of the same conditions observed in separate patients.

CONCLUSION

Prevalent morbidity combinations, rather than high-cost ones, made a greater contribution to total national health expenditure. Our study contributes to the sparse evidence on this topic globally and in Europe, with the aim of improving cost-effective care for patients with diverse needs.

Adoption and Sustained Use of Primary Care Video Visits Among Veterans with VA Video-Enabled Tablets

In 2020, the U.S. Department of Veterans Affairs (VA) expanded an initiative to distribute video-enabled tablets to Veterans with limited virtual care access. We examined patient characteristics associated with adoption and sustained use of video-based primary care among Veterans. We conducted a retrospective cohort study of Veterans who received VA-issued tablets between 3/11/2020-9/10/2020. We used generalized linear models to evaluate the sociodemographic and clinical factors associated with video-based primary care adoption (i.e., likelihood of having a primary care video visit) and sustained use (i.e., rate of video care) in the six months after a Veteran received a VA-issued tablet. Of the 36,077 Veterans who received a tablet, 69% had at least one video-based visit within six months, and 24% had a video-based visit in primary care. Veterans with a history of housing instability or a mental health condition, and those meeting VA enrollment criteria for low-income were significantly less likely to adopt video-based primary care. However, among Veterans who had a video visit in primary care (e.g., those with at least one video visit), older Veterans, and Veterans with a mental health condition had more sustained use (higher rate) than younger Veterans or those without a mental health condition. We found no differences in adoption of video-based primary care by rurality, age, race, ethnicity, or low/moderate disability and high disability priority groups compared to Veterans with no special enrollment category. VA's tablet initiative has supported many Veterans with complex needs in accessing primary care by video. While Veterans with certain social and clinical challenges were less likely to have a video visit, those who adopted video telehealth generally had similar or higher rates of sustained use. These patterns suggest opportunities for tailored interventions that focus on needs specific to initial uptake vs. sustained use of video care.

Impact of VA's video telehealth tablets on substance use disorder care during the COVID-19 pandemic

BACKGROUND

Telehealth has the potential to improve health care access for patients but it has been underused and understudied for examining patients with substance use disorders (SUD). VA began distributing video-enabled tablets to veterans with access barriers in 2016 to facilitate participation in home-based telehealth and expanded this program in 2020 due to the coronavirus COVID-19 pandemic.

OBJECTIVE

Examine the impact of VA's video-enabled telehealth tablets on mental health services for patients diagnosed with SUD.

METHODS

This study included VA patients who had ≥1 mental health visit in the calendar year 2019 and a documented diagnosis of SUD. Using difference-in-differences and event study designs, we compared outcomes for SUD-diagnosed patients who received a video-enabled tablet from VA between March 15th, 2020 and December 31st, 2021 and SUD-diagnosed patients who never received VA tablets, 10 months before and after tablet-issuance. Outcomes included monthly frequency of SUD psychotherapy visits, SUD specialty group therapy visits and SUD specialty individual outpatient visits. We examined changes in video visits and changes in visits across all modalities of care (video, phone, and in-person). Regression models adjusted for several covariates such as age, sex, rurality, race, ethnicity, physical and mental health chronic conditions, and broadband coverage in patients' residential zip-code.

RESULTS

The cohort included 21,684 SUD-diagnosed tablet-recipients and 267,873 SUD-diagnosed non-recipients. VA's video-enabled tablets were associated with increases in video visits for SUD psychotherapy (+3.5 visits/year), SUD group therapy (+2.1 visits/year) and SUD individual outpatient visits (+1 visit/year), translating to increases in visits across all modalities (in-person, phone and video): increase of 18 % for SUD psychotherapy (+1.9 visits/year), 10 % for SUD specialty group therapy (+0.5 visit/year), and 4 % for SUD specialty individual outpatient treatment (+0.5 visit/year).

CONCLUSIONS

VA's distribution of video-enabled tablets during the COVID-19 pandemic were associated with higher engagement with video-based services for SUD care among patients diagnosed with SUD, translating to modest increases in total visits across in-person, phone and video modalities. Distribution of video-enabled devices can offer patients critical continuity of SUD therapy, particularly in scenarios where they have heightened barriers to in-person care.

Variation in initial and continued use of primary, mental health, and specialty video care among Veterans

OBJECTIVE

To identify which Veteran populations are routinely accessing video-based care.

DATA SOURCES AND STUDY SETTING

National, secondary administrative data from electronic health records at the Veterans Health Administration (VHA), 2019-2021.

STUDY DESIGN

This retrospective cohort analysis identified patient characteristics associated with the odds of using any video care; and then, among those with a previous video visit, the annual rate of video care utilization. Video care use was reported overall and stratified into care type (e.g., primary, mental health, and specialty video care) between March 10, 2020 and February 28, 2021.

DATA COLLECTION

Veterans active in VA health care (>1 outpatient visit between March 11, 2019 and March 10, 2020) were included in this study.

PRINCIPAL FINDINGS

Among 5,389,129 Veterans in this evaluation, approximately 27.4% of Veterans had at least one video visit. We found differences in video care utilization by type of video care: 14.7% of Veterans had at least one primary care video visit, 10.6% a mental health video visit, and 5.9% a specialty care video visit. Veterans with a history of housing instability had a higher overall rate of video care driven by their higher usage of video for mental health care compared with Veterans in stable housing. American Indian/Alaska Native Veterans had reduced odds of video visits, yet similar rates of video care when compared to White Veterans. Low-income Veterans had lower odds of using primary video care yet slightly elevated rates of primary video care among those with at least one video visit when compared to Veterans enrolled at VA without special considerations.

CONCLUSIONS

Variation in video care utilization patterns by type of care identified Veteran populations that might require greater resources and support to initiate and sustain video care use. Our data support service specific outreach to homeless and American Indian/Alaska Native Veterans.

Overcoming Access Barriers for Veterans: Cohort Study of the Distribution and Use of Veterans Affairs' Video-Enabled Tablets Before and During the COVID-19 Pandemic

BACKGROUND

During the COVID-19 pandemic, as health care services shifted to video- and phone-based modalities for patient and provider safety, the Veterans Affairs (VA) Office of Connected Care widely expanded its video-enabled tablet program to bridge digital divides for veterans with limited video care access.

OBJECTIVE

This study aimed to characterize veterans who received and used US Department of VA-issued video-enabled tablets before versus during the COVID-19 pandemic.

METHODS

We compared sociodemographic and clinical characteristics of veterans who received VA-issued tablets during 6-month prepandemic and pandemic periods (ie, from March 11, 2019, to September 10, 2019, and from March 11, 2020, to September 10, 2020). Then, we examined characteristics associated with video visit use for primary and mental health care within 6 months after tablet shipment, stratifying models by timing of tablet receipt.

RESULTS

There was a nearly 6-fold increase in the number of veterans who received tablets in the pandemic versus prepandemic study periods (n=36,107 vs n=6784, respectively). Compared to the prepandemic period, tablet recipients during the pandemic were more likely to be older (mean age 64 vs 59 years), urban-dwelling (24,504/36,107, 67.9% vs 3766/6784, 55.5%), and have a history of housing instability (8633/36,107, 23.9% vs 1022/6784, 15.1%). Pandemic recipients were more likely to use video care (21,090/36,107, 58.4% vs 2995/6784, 44.2%) and did so more frequently (5.6 vs 2.3 average encounters) within 6 months of tablet receipt. In adjusted models, pandemic and prepandemic video care users were significantly more likely to be younger, stably housed, and have a mental health condition than nonusers.

CONCLUSIONS

Although the COVID-19 pandemic led to increased distribution of VA-issued tablets to veterans with complex clinical and social needs, tablet recipients who were older or unstably housed remained less likely to have a video visit. The VA's tablet distribution program expanded access to video-enabled devices, but interventions are needed to bridge disparities in video visit use among device recipients.

Disparities in virtual cardiology visits among Veterans Health Administration patients during the COVID-19 pandemic

Objective

In response to the coronavirus disease 2019 (COVID-19) pandemic, the Veterans Health Administration (VA) rapidly expanded virtual care (defined as care delivered by video and phone), raising concerns about technology access disparities (ie, the digital divide). Virtual care was somewhat established in primary care and mental health care prepandemic, but video telehealth implementation was new for most subspecialties, including cardiology. We sought to identify patient characteristics of virtual and video-based care users in VA cardiology clinics nationally during the first year of the COVID-19 pandemic.

Materials and Methods

Cohort study of Veteran patients across all VA facilities with a cardiology visit January 1, 2019-March 10, 2020, with follow-up January 1, 2019-March 10, 2021. Main measures included cardiology visits by visit type and likelihood of receiving cardiology-related virtual care, calculated with a repeated event survival model.

Results

416 587 Veterans with 1 689 595 total cardiology visits were analyzed; average patient age was 69.6 years and 4.3% were female. Virtual cardiology care expanded dramatically early in the COVID-19 pandemic from 5% to 70% of encounters. Older, lower-income, and rural-dwelling Veterans and those experiencing homelessness were less likely to use video care (adjusted hazard ratio for ages 75 and older 0.80, 95% confidence interval (CI) 0.75-0.86; for highly rural residents 0.77, 95% CI 0.68-0.87; for low-income status 0.94, 95% CI 0.89-0.98; for homeless Veterans 0.85, 95% CI 0.80-0.92).

Conclusion

The pandemic worsened the digital divide for cardiology care for many vulnerable patients to the extent that video visits represent added value over phone visits. Targeted interventions may be necessary for equity in COVID-19-era access to virtual cardiology care.

Mental Health Service Use, Suicide Behavior, and Emergency Department Visits Among Rural US Veterans Who Received Video-Enabled Tablets During the COVID-19 Pandemic

IMPORTANCE

Suicide rates are rising disproportionately in rural counties, a concerning pattern as the COVID-19 pandemic has intensified suicide risk factors in these regions and exacerbated barriers to mental health care access. Although telehealth has the potential to improve access to mental health care, telehealth's effectiveness for suicide-related outcomes remains relatively unknown.

OBJECTIVE

To evaluate the association between the escalated distribution of the US Department of Veterans Affairs' (VA's) video-enabled tablets during the COVID-19 pandemic and rural veterans' mental health service use and suicide-related outcomes.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study included rural veterans who had at least 1 VA mental health care visit in calendar year 2019 and a subcohort of patients identified by the VA as high-risk for suicide. Event studies and difference-in-differences estimation were used to compare monthly mental health service utilization for patients who received VA tablets during COVID-19 with patients who were not issued tablets over 10 months before and after tablet shipment. Statistical analysis was performed from November 2021 to February 2022.

EXPOSURE

Receipt of a video-enabled tablet.

MAIN OUTCOMES AND MEASURES

Mental health service utilization outcomes included psychotherapy visits, medication management visits, and comprehensive suicide risk evaluations (CSREs) via video and total visits across all modalities (phone, video, and in-person). We also analyzed likelihood of emergency department (ED) visit, likelihood of suicide-related ED visit, and number of VA's suicide behavior and overdose reports (SBORs).

RESULTS

The study cohort included 13 180 rural tablet recipients (11 617 [88%] men; 2161 [16%] Black; 301 [2%] Hispanic; 10 644 [80%] White; mean [SD] age, 61.2 [13.4] years) and 458 611 nonrecipients (406 545 [89%] men; 59 875 [13%] Black or African American; 16 778 [4%] Hispanic; 384 630 [83%] White; mean [SD] age, 58.0 [15.8] years). Tablets were associated with increases of 1.8 psychotherapy visits per year (monthly coefficient, 0.15; 95% CI, 0.13-0.17), 3.5 video psychotherapy visits per year (monthly coefficient, 0.29; 95% CI, 0.27-0.31), 0.7 video medication management visits per year (monthly coefficient, 0.06; 95% CI, 0.055-0.062), and 0.02 video CSREs per year (monthly coefficient, 0.002; 95% CI, 0.002-0.002). Tablets were associated with an overall 20% reduction in the likelihood of an ED visit (proportion change, -0.012; 95% CI, -0.014 to -0.010), a 36% reduction in the likelihood of suicide-related ED visit (proportion change, -0.0017; 95% CI, -0.0023 to -0.0013), and a 22% reduction in the likelihood of suicide behavior as indicated by SBORs (monthly coefficient, -0.0011; 95% CI, -0.0016 to -0.0005). These associations persisted for the subcohort of rural veterans the VA identifies as high-risk for suicide.

CONCLUSIONS AND RELEVANCE

This cohort study of rural US veterans with a history of mental health care use found that receipt of a video-enabled tablet was associated with increased use of mental health care via video, increased psychotherapy visits (across all modalities), and reduced suicide behavior and ED visits. These findings suggest that the VA and other health systems should consider leveraging video-enabled tablets for improving access to mental health care via telehealth and for preventing suicides among rural residents.

A comparative analysis and review of how national guidelines for chronic disease monitoring are made in low- and middle-income compared to high-income countries

Background

Understanding how clinical practice guidelines and recommendations are adopted in high-income and low-income settings will help contextualise the value and validity of recommendations in different settings. We investigate how major guidelines and recommendations are developed for management and monitoring of post-diagnosis treatment for three important chronic diseases: HIV, hypertension and type 2 diabetes mellitus (T2DM).

Methods

Eligible guidelines were searched for using PubMed, Google, and health ministry websites for all three conditions. Only guidelines published from 2010 to 2020 were included. The source of the guidelines, year of most recent guideline, and basis of the guidelines were assessed. Additionally, recommendations, the strength of the recommendation and the quality of the evidence for treatment goals of non-pregnant adults and the frequency of monitoring were also extracted and assessed.

Results

Of the 42 countries searched 90%, 71% and 60% had T2DM, hypertension and HIV guidelines outlining targets for long-term management, respectively. Most T2DM guidelines recommend an HbA1c target of ≤7.0% (68%) or ≤6.5% (24%) as the ideal glycaemic target for most non-pregnant adults, while hypertension guidelines recommend blood pressure (systolic blood pressure/diastolic blood pressure) targets of <140/90 mm Hg (94%) and <130/80 mm Hg (6%). Of the identified HIV guidelines, 67% define virological failure as a viral load >1000 copies/mL, with 26%, mostly HICs, defining virological failure as a viral load >200 copies/mL. Recommendations for the frequency of monitoring for any diagnosed patients were available in 18 (55%) of the hypertension guidelines, 25 (93%) of HIV guidelines, and 27 (73%) of the T2DM guidelines. Only a few of the guidelines provide the strength of the recommendation and the quality of the evidence.

Conclusions

Most guidelines from LMICs are adopted or adapted from existing HIC guidelines or international and regional organisation guidelines with little consideration for resource availability, contextual factors, logistical issues and general feasibility.

Virtual care expansion in the Veterans Health Administration during the COVID-19 pandemic: clinical services and patient characteristics associated with utilization

Objectives

To describe the shift from in-person to virtual care within Veterans Affairs (VA) during the early phase of the COVID-19 pandemic and to identify at-risk patient populations who require greater resources to overcome access barriers to virtual care.

Materials and Methods

Outpatient encounters (N = 42 916 349) were categorized by care type (eg, primary, mental health, etc) and delivery method (eg, in-person, video). For 5 400 878 Veterans, we used generalized linear models to identify patient sociodemographic and clinical characteristics associated with: 1) use of virtual (phone or video) care versus no virtual care and 2) use of video care versus no video care between March 11, 2020 and June 6, 2020.

Results

By June, 58% of VA care was provided virtually compared to only 14% prior. Patients with lower income, higher disability, and more chronic conditions were more likely to receive virtual care during the pandemic. Yet, Veterans aged 45–64 and 65+ were less likely to use video care compared to those aged 18–44 (aRR 0.80 [95% confidence interval (CI) 0.79, 0.82] and 0.50 [95% CI 0.48, 0.52], respectively). Rural and homeless Veterans were 12% and 11% less likely to use video care compared to urban (0.88 [95% CI 0.86, 0.90]) and nonhomeless Veterans (0.89 [95% CI 0.86, 0.92]).

Discussion

Veterans with high clinical or social need had higher likelihood of virtual service use early in the COVID-19 pandemic; however, older, homeless, and rural Veterans were less likely to have video visits, raising concerns for access barriers.

Conclusions and Relevance

While virtual care may expand access, access barriers must be addressed to avoid exacerbating disparities.

Multiple chronic conditions at a major urban health system: a retrospective cross-sectional analysis of frequencies, costs and comorbidity patterns

OBJECTIVE

To (1) examine the burden of multiple chronic conditions (MCC) in an urban health system, and (2) propose a methodology to identify subpopulations of interest based on diagnosis groups and costs.

DESIGN

Retrospective cross-sectional study.

SETTING

Mount Sinai Health System, set in all five boroughs of New York City, USA.

PARTICIPANTS

192 085 adult (18+) plan members of capitated Medicaid contracts between the Healthfirst managed care organisation and the Mount Sinai Health System in the years 2012 to 2014.

METHODS

We classified adults as having 0, 1, 2, 3, 4 or 5+ chronic conditions from a list of 69 chronic conditions. After summarising the demographics, geography and prevalence of MCC within this population, we then described groups of patients (segments) using a novel methodology: we combinatorially defined 18 768 potential segments of patients by a pair of chronic conditions, a sex and an age group, and then ranked segments by (1) frequency, (2) cost and (3) ratios of observed to expected frequencies of co-occurring chronic conditions. We then compiled pairs of conditions that occur more frequently together than otherwise expected.

RESULTS

61.5% of the study population suffers from two or more chronic conditions. The most frequent dyad was hypertension and hyperlipidaemia (19%) and the most frequent triad was diabetes, hypertension and hyperlipidaemia (10%). Women aged 50 to 65 with hypertension and hyperlipidaemia were the leading cost segment in the study population. Costs and prevalence of MCC increase with number of conditions and age. The disease dyads associated with the largest observed/expected ratios were pulmonary disease and myocardial infarction. Inter-borough range MCC prevalence was 16%.

CONCLUSIONS

In this low-income, urban population, MCC is more prevalent (61%) than nationally (42%), motivating further research and intervention in this population. By identifying potential target populations in an interpretable manner, this segmenting methodology has utility for health services analysts.

The global burden of multiple chronic conditions: A narrative review

Globally, approximately one in three of all adults suffer from multiple chronic conditions (MCCs). This review provides a comprehensive overview of the resulting epidemiological, economic and patient burden. There is no agreed taxonomy for MCCs, with several terms used interchangeably and no agreed definition, resulting in up to three-fold variation in prevalence rates: from 16% to 58% in UK studies, 26% in US studies and 9.4% in Urban South Asians. Certain conditions cluster together more frequently than expected, with associations of up to three-fold, e.g. depression associated with stroke and with Alzheimer's disease, and communicable conditions such as TB and HIV/AIDS associated with diabetes and CVD, respectively. Clusters are important as they may be highly amenable to large improvements in health and cost outcomes through relatively simple shifts in healthcare delivery. Healthcare expenditures greatly increase, sometimes exponentially, with each additional chronic condition with greater specialist physician access, emergency department presentations and hospital admissions. The patient burden includes a deterioration of quality of life, out of pocket expenses, medication adherence, inability to work, symptom control and a high toll on carers. This high burden from MCCs is further projected to increase. Recommendations for interventions include reaching consensus on the taxonomy of MCC, greater emphasis on MCCs research, primary prevention to achieve compression of morbidity, a shift of health systems and policies towards a multiple-condition framework, changes in healthcare payment mechanisms to facilitate this change and shifts in health and epidemiological databases to include MCCs.

Different pain responses to chronic and acute pain in various ethnic/racial groups

AIM

Our goal in this study was to review the similarities and differences among ethnic groups and their respective responses to acute and chronic clinically related and experimentally induced pain.

METHOD

In this review, the PUBMED and Google-Scholar databases were searched to analyze articles that have assessed the variations in both acute and chronic pain responses among different ethnic/racial groups.

RESULTS

According to the results from 42 reviewed articles, significant differences exist among ethnic-racial groups for pain prevalence as well as responses to acute and chronic pain. Compared with Caucasians, other ethnic groups are more susceptible to acute pain responses to nociceptive stimulation and to the development of long-term chronic pain.

CONCLUSION

These differences need to be addressed and assessed more extensively in the future in order to minimize the pain management disparities among various ethnic-racial groups and also to improve the relationship between pain management providers and their patients.

Changes in Veteran Tobacco Use Identified in Electronic Medical Records

INTRODUCTION

Electronic medical records represent a new source of longitudinal data on tobacco use.

METHODS

Electronic medical records of the U.S. Department of Veterans Affairs were extracted to find patients' tobacco use status in 2009 and at another assessment 12-24 months later. Records from the year prior to the first assessment were used to determine patient demographics and comorbidities. These data were analyzed in 2015.

RESULTS

An annual quit rate of 12.0% was observed in 754,504 current tobacco users. Adjusted tobacco use prevalence at follow-up was 3.2% greater with alcohol use disorders at baseline, 1.9% greater with drug use disorders, 3.3% greater with schizophrenia, and lower in patients with cancer, heart disease, and other medical conditions (all differences statistically significant with p<0.05). Annual relapse rates in 412,979 former tobacco users were 29.6% in those who had quit for <1 year, 9.7% in those who had quit for 1-7 years, and 1.9% of those who had quit for >7 years. Among those who had quit for <1 year, adjusted relapse rates were 4.3% greater with alcohol use disorders and 7.2% greater with drug use disorders (statistically significant with p<0.05).

CONCLUSIONS

High annual cessation rates may reflect the older age and greater comorbidities of the cohort or the intensive cessation efforts of the U.S. Department of Veterans Affairs. The lower cessation and higher relapse rates in psychiatric and substance use disorders suggest that these groups will need intensive and sustained cessation efforts.

Prevalence and Costs of Chronic Conditions in the VA Health Care System

Chronic conditions are among the most common causes of death and disability in the United States. Patients with such conditions receive disproportionate amounts of health care services and therefore cost more per capita than the average patient. This study assesses the prevalence among the Department of Veterans Affairs (VA) health care users and VA expenditures (costs) of 29 common chronic conditions. The authors used regression to identify the marginal impact of these conditions on total, inpatient, outpatient, and pharmacy costs. Excluding costs of contracted medical services at non-VA facilities, total VA health care expenditures in fiscal year 1999 (FY1999) were $14.3 billion. Among the 3.4 million VA patients in FY1999, 72 percent had 1 or more of the 29 chronic conditions, and these patients accounted for 96 percent of the total costs ($13.7 billion). In addition, 35 percent (1.2 million) of VA health care users had 3 or more of the 29 chronic conditions. These individuals accounted for 73 percent of the total cost. Overall, VA health care users have more chronic diseases than the general population.

The economic impact of chronic pain: a nationwide population-based cost-of-illness study in Portugal

In addition to its high frequency and relevant individual and social impact, chronic pain (CP) has been shown to be a major contributor to increased healthcare utilisation, reduced labour productivity, and consequently large direct and indirect costs. In the context of a larger nationwide study, we aimed to assess the total annual direct and indirect costs associated with CP in Portugal. A population-based study was conducted in a representative sample of the Portuguese adult population. The 5,094 participants were selected using random digit dialling and contacted by computer-assisted telephone interviews. Questionnaires included the brief pain inventory and pain disability index. Estimates were adequately weighted for the population. From all CP subjects identified, a subsample (n = 562) accepted to participate in this economic study. Mean total annualised costs per CP subject of €1,883.30 were observed, amounting to €4,611.69 million nationally, with 42.7% direct and 57.3% indirect costs, and corresponding to 2.71% of the Portuguese annual GDP in 2010. Only socio-demographic variables were significantly and independently associated with CP costs, and not CP severity, raising the possibility of existing inequalities in the distribution of healthcare in Portugal. The high economic impact of CP in Portugal was comprehensively demonstrated. Given the high indirect costs observed, restricting healthcare services is not a rational response to these high societal costs; instead improving the quality of CP prevention and management is recommended.

Cost of Chronic and Episodic Migraine. A pilot study from a tertiary headache centre in northern Italy

BACKGROUND

Chronic migraine (CM) has a high impact on functional performance and quality of life (QoL). CM also has a relevant burden on the National Health Service (NHS), however precise figures are lacking. In this pilot study we compared the impact in terms of costs of CM and episodic migraine (EM) on the individual and on the National Health System (NHS). Furthermore, we comparatively evaluated the impact of CM and EM on functional capability and on QoL of sufferers.

METHODS

We enrolled 92 consecutive patients attending the Pavia headache centre: 51 subjects with CM and 41 with episodic migraine (EM). Patients were tested with disability scales (MIDAS, HIT-6, SF-36) and with an ad hoc semi-structured questionnaire.

RESULTS

The direct mean annual cost (in euro) per patient suffering from CM was €2250.0 ± 1796.1, against €523.6 ± 825.8 per patient with EM. The cost loaded on NHS was €2110.4 ± 1756.9 for CM, €468.3 ± 801.8 for EM. The total economic load and the different sub-items were significantly different between groups (CM vs. EM p = 0.001 for each value). CM subjects had higher scores than EM for MIDAS (98.4 ± 72,3 vs 15.5 ± 17.7, p = 0.001) and for HIT-6 (66.1 ± 8.4 vs 58.7 ± 10.1, p = 0.001). The SF-36 score was 39.9 ± 14,74 for CM and 66.2 ± 18.2 for EM (p = 0.001).

CONCLUSIONS

CM is a disabling condition with a huge impact on the QoL of sufferers and a significant economic impact on the NHS. The adequate management of CM, reverting it back to EM, will provide a dual benefit: on the individual and on the society.

Inpatient management of migraine

Migraine is a frequently disabling disorder which may require inpatient treatment. Admission criteria for migraine include intractable migraine, nausea and/or vomiting, severe disability, and dependence on opioids or barbiturates. The inpatient treatment of migraine is based on observational studies and expert opinion rather than placebo-controlled trials. Well-established inpatient treatments for migraine include dihydroergotamine, neuroleptics/antiemetics, lidocaine, intravenous aspirin, and non-pharmacologic treatment such as cognitive-behavioral therapy. Short-acting treatments possibly associated with medication overuse, such as triptans, opioids, or barbiturate-containing compounds, are generally avoided. While the majority of persons with migraine are admitted on an emergency basis for only a few days, outcome studies and infusion protocols during elective admissions at tertiary headache centers suggest a longer length of stay may be needed for persons with intractable migraine.

[Effects of multimorbidity on health care utilization and costs]

Multiple chronic conditions (multimorbidity) are common among elderly patients; however, little is known about the specific effects of multimorbidity on health care utilization and health care costs. This article reviews empirical studies from the international literature that investigated the relationship between multiple chronic conditions and health care utilization (e.g. ambulatory care, stationary care, pharmacotherapy) and/or health care costs in elderly general populations. Although synthesis of studies was complicated, especially because of ambiguous definitions and measurements of multimorbidity, almost all studies observed a positive association of multimorbidity and utilization and costs. Many studies found that utilization and costs significantly increased with each additional chronic condition. In light of these findings coupled with the fear that current care arrangements may be inappropriate for many multimorbid patients, important implications for research and policy are presented and discussed.

Identifying neck and back pain in administrative data: defining the right cohort

STUDY DESIGN

We reviewed existing methods for identifying patients with neck and back pain in administrative data. We compared these methods using data from the Department of Veterans Affairs.

OBJECTIVE

To answer the following questions: (1) what diagnosis codes should be used to identify patients with neck pain and back pain in administrative data; (2) because the majority of complaints are characterized as nonspecific or mechanical, what diagnosis codes should be used to identify patients with nonspecific or mechanical problems in administrative data; and (3) what procedure and surgical codes should be used to identify patients who have undergone a surgical procedure on the neck or back.

SUMMARY OF BACKGROUND DATA

Musculoskeletal neck and back pain are pervasive problems, associated with chronic pain, disability, and high rates of health care utilization. Administrative data have been widely used in formative research, which has largely relied on the original work of Volinn, Cherkin, Deyo, and Einstadter and the Back Pain Patient Outcomes Assessment Team first published in 1992. Significant variation in reports of incidence, prevalence, and morbidity associated with these problems may be due to nonstandard or conflicting methods to define study cohorts.

METHODS

A literature review produced 7 methods for identifying neck and back pain in administrative data. These code lists were used to search Veterans Health Administration data for patients with back and neck problems, and to further categorize each case by spinal segment involved, as nonspecific/mechanical and as surgical or not.

RESULTS

There is considerable overlap in most algorithms. However, gaps persist.

CONCLUSION

Gaps are evident in existing methods and a new framework to identify patients with neck pain and back pain in administrative data is proposed.

How are the costs of care for medical falls distributed? The costs of medical falls by component of cost, timing, and injury severity

PURPOSE OF THE STUDY

To examine the components of cost that drive increased total costs after a medical fall over time, stratified by injury severity.

DESIGN AND METHODS

We used 2004-2007 cost and utilization data for persons enrolled in an integrated care delivery system. We used a longitudinal cohort study design, where each individual provides 2-3 years of administrative data grouped into 3-month intervals relative to an index date. We identified 8,969 medical fallers through International Classification of Diseases, 9th Revision, codes and E-Codes and used 8,956 nonfaller controls, identified through age and gender frequency matching. Total costs were partitioned into 7 components: inpatient, outpatient, emergency, radiology, pharmacy, postacute care, and "other."

RESULTS

The large increase in costs after a hospitalized fall is mainly associated with inpatient and postacute care components. The spike in costs after a nonhospitalized fall is attributable to outpatient and "other" (e.g., ambulatory surgery or community health services) components. Hospitalized fallers' inpatient, emergency, postacute care, outpatient, and radiology costs are not always greater than those for nonhospitalized fallers.

IMPLICATIONS

Components associated with increased costs after a medical fall vary over time and by injury severity. Future studies should compare if delivering certain acute and postacute health services improve health and reduce cost trajectories after a medical fall more than others. Additionally, since the older adult population and the problem of falls are growing, health care delivery systems should develop standardized methodology to monitor medical fall rates.

Recent trends in Veterans Affairs chronic condition spending

The change in prevalence and total Veterans Affairs (VA) spending were estimated for 16 chronic condition categories between 2000 and 2008. The drivers of changes in spending also were examined. Chronic conditions were identified through diagnoses in encounter records, and treatment costs per patient were estimated using VA cost data and regression models. The estimated differences in total VA spending between 2000 and 2008 and the contributions of population increase, differences in prevalence, and differences in treatment costs were evaluated. Most of the spending increases during the study period were driven by the increase in the VA patient population from 3.3 million in 2000 to 4.9 million in 2008. Spending on renal failure increased the most, by more than $1.5 billion, primarily because of higher prevalence. Higher treatment costs did not contribute much to higher spending; lower costs per patient for several conditions may have helped to slow spending for diabetes, chronic obstructive pulmonary disease, heart conditions, renal failure, dementia, and stroke. Lowering treatment costs per patient for common conditions can help slow spending for chronic conditions, but most of the increase in spending in the study period was the result of more patients seeking care from VA providers and the higher prevalence of conditions among patients. As the VA patient population continues to age and to develop more co-morbidities, and as returning veterans seek care for service-related problems, higher spending on chronic conditions will become a more prominent issue for the VA health care system.

Accountable disease management of spine pain

The health care landscape has changed with new legislation addressing the unsustainable rise in costs in the US system. Low-value service lines caring for expensive chronic conditions have been targeted for reform; for better or worse, the treatment of spine pain has been recognized as a representative example. Examining the Patient Protection and Affordable Care Act and existing pilot studies can offer a preview of how chronic care of spine pain will be sustained. Accountable care in an organization capable of collecting, analyzing, and reporting clinical data and operational compliance is forthcoming. Interdisciplinary spine pain centers integrating surgical and medical management, behavioral medicine, physical reconditioning, and societal reintegration represent the model of high-value care for patients with chronic spine pain.

Review: Health Care Utilization and Costs of Elderly Persons With Multiple Chronic Conditions

This systematic literature review identified and summarized 35 studies that investigated the relationship between multiple chronic conditions (MCCs) and health care utilization outcomes (i.e. physician use, hospital use, medication use) and health care cost outcomes (medication costs, out-of-pocket costs, total health care costs) for elderly general populations. Although synthesis of studies was complicated because of ambiguous definitions and measurements of MCCs, and because of the multitude of outcomes investigated, almost all studies observed a positive association of MCCs and use/costs, many of which found that use/costs significantly increased with each additional condition. Several studies indicate a curvilinear, near exponential relationship between MCCs and costs. The rising prevalence, substantial costs, and the fear that current care arrangements may be inappropriate for many patients with MCCs, bring about a multitude of implications for research and policy, of which the most important are presented and discussed.

Health status of the advanced elderly in six European countries: results from a representative survey using EQ-5D and SF-12

Background

Due to demographic change, the advanced elderly represent the fastest growing population group in Europe. Health problems tend to be frequent and increasing with age within this cohort.

Aims of the study

To describe and compare health status of the elderly population in six European countries and to analyze the impact of socio-demographic variables on health.

Methods

In the European Study of the Epidemiology of Mental Disorders (ESEMeD), representative non-institutionalized population samples completed the EQ-5D and Short Form-12 (SF-12) questionnaires as part of personal computer-based home interviews in 2001-2003. This study is based on a subsample of 1659 respondents aged ≥ 75 years from Belgium (n = 194), France (n = 168), Germany (n = 244), Italy (n = 317), the Netherlands (n = 164) and Spain (n = 572). Descriptive statistics, bivariate- (chi-square tests) and multivariate methods (linear regressions) were used to examine differences in population health.

Results

68.8% of respondents reported problems in one or more EQ-5D dimensions, most frequently pain/discomfort (55.2%), followed by mobility (50.0%), usual activities (36.6%), self-care (18.1%) and anxiety/depression (11.6%). The proportion of respondents reporting any problems increased significantly with age in bivariate analyses (age 75-79: 65.4%; age 80-84: 69.2%; age ≥ 85: 81.1%) and differed between countries, ranging from 58.7% in the Netherlands to 72.3% in Italy. The mean EQ VAS score was 61.9, decreasing with age (age 75-79: 64.1; age 80-84: 59.8; age ≥ 85: 56.7) and ranging from 60.0 in Italy to 72.9 in the Netherlands. SF-12 derived Physical Component Summary (PCS) and Mental Component Summary (MCS) scores varied little by age and country. Age and low educational level were associated with lower EQ VAS and PCS scores. After controlling for socio-demographic variables and reported EQ-5D health states, mean EQ VAS scores were significantly higher in the Netherlands and Belgium, and lower in Germany than the grand mean.

Conclusions

More than two thirds of the advanced elderly report impairment of health status. Impairment increases rapidly with age but differs considerably between countries. In all countries, health status is significantly associated with socio-demographic variables.

A diffusion tensor magnetic resonance imaging study of corpus callosum from adult patients with migraine complicated with depressive/anxious disorder

OBJECTIVE

The aim of this study was to investigate the possible microstructural abnormalities of the corpus callosum (CC) in adult patients with migraine without aura complicated with depressive/anxious disorder.

BACKGROUND

Emotional disorders, especially depression and anxiety, are with relatively higher incidence in migraine population. However, the mechanism of migraine complicated with depressive/anxious disorder remains unclear.

METHODS

Diffusion tensor magnetic resonance imaging was carried out in 12 adult patients with simple migraine (without aura and without depressive/anxious disorder) (S-M group), 12 adult patients with complicated migraine (without aura but complicated with depressive/anxious disorder) (Co-M group), and 12 age- and sex-matched healthy subjects (Control group). Fractional anisotropy (FA) and apparent diffusion coefficient were measured at genu, body, and splenium of the CC, respectively.

RESULTS

There were significant differences in FA values at all locations of the CC among the 3 groups. The FA values from both the SM and Co-M groups were significantly lower than the control (P < .05 and P < .01, respectively). The FA values from Co-M group were significantly lower than the SM group (P < .01). The apparent diffusion coefficient values of the above regions had no significant differences among these groups (P > .05). There were negative correlations between FA value of genu of the CC and disease course as well as FA value of genu and body of the CC and headache frequency (P < .05). Negative correlations were also found between FA values at all locations of the CC and Hamilton anxiety and Hamilton depression scores (both P < .05).

CONCLUSIONS

There might be an integrity change of neurofibrotic microstructures existing as a possible neuroanatomical basis in the CC of migraine patients complicated with depressive/anxious disorder.

Systems of support to increase colorectal cancer screening and follow-up rates (SOS): design, challenges, and baseline characteristics of trial participants

BACKGROUND

Screening decreases colorectal cancer (CRC) morbidity and mortality, yet remains underutilized. Screening breakdowns arise from lack of uptake and failure to follow-up after a positive screening test.

OBJECTIVES

Systems of support to increase colorectal cancer screening and follow-up (SOS) is a randomized trial designed to increase: (1) CRC screening and (2) follow-up of positive screening tests. The Chronic Care Model and the Preventive Health Model inform study design.

METHODS

The setting is a large nonprofit healthcare organization. In part-1 study, patients age 50-75 due for CRC screening are randomized to one of 4 study conditions. Arm 1 receives usual care. Arm 2 receives automated support (mailed information about screening choices and fecal occult blood tests (FOBT)). Arm 3 receives automated and assisted support (a medical assistant telephone call). Arm 4 receives automated, assisted, and care management support (a registered nurse provides behavioral activation and coordination of care). In part-2, study patients with a positive FOBT or adenomas on flexible sigmoidoscopy are randomized to receive either usual care or nurse care management. Primary outcomes are: 1) the proportion with CRC screening, 2) the proportion with a complete diagnostic evaluation after a positive screening test.

RESULTS

We sent recruitment letters to 15,414 patients and 4675 were randomized. Randomly assigned treatment groups were similar in age, sex, race, education, self-reported health, and CRC screening history.

CONCLUSIONS

We will determine the effectiveness and cost effectiveness of stepped increases in systems of support to increase CRC screening and follow-up after a positive screening test over 2years.

A longitudinal analysis of total 3-year healthcare costs for older adults who experience a fall requiring medical care

OBJECTIVES

To compare longitudinal changes in healthcare costs between fallers admitted to the hospital at the time of the fall (admitted), those not admitted to the hospital (nonadmitted), and nonfaller controls; test hypotheses related to differences in mean costs between and within these groups over time; and estimate the costs attributable to falling.

DESIGN

Longitudinal cohort.

SETTING

Group Health Cooperative of Puget Sound.

PARTICIPANTS

Seven thousand nine hundred ninety-three nonadmitted fallers, 976 admitted fallers, and 8,956 nonfallers aged 67 and older enrolled in an integrated healthcare delivery system. Fallers were identified according to fall-related E-Codes and International Classification of Diseases, Ninth Revision codes recorded between January 1, 2004, and December 31, 2006. Nonfallers were frequency matched on age group and sex.

MEASUREMENTS

Quarterly costs during a 3-year period were modeled using generalized estimating equations. Covariates included index age, sex, RxRisk (a comorbidity adjuster), fall status, time, and interactions between fall status and time.

RESULTS

Cost differences between the faller cohorts and nonfallers were greatest in quarters closest to the fall (all P<.01) and persisted throughout the entire year of follow-up. Although nonfaller costs increased with time, faller cohort costs increased more quickly (all P<.01). For admitted fallers, 92% of costs incurred in the quarter of the fall were estimated to be attributable to falling ($27,745 of $30,038, P<.001).

CONCLUSION

Falls for which medical attention are sought resulted in higher costs than for nonfallers for up to 12 months after a fall, particularly for falls requiring hospitalization. Prevention efforts should focus on reducing fall-related injuries requiring hospitalization because they produce the highest excess costs and have a higher likelihood of 1-year mortality.

Health care utilization and costs by metabolic syndrome risk factors

BACKGROUND

This study compared prevalent health utilization and costs for persons with and without metabolic syndrome and investigated the independent associations of the various factors that make up metabolic syndrome.

METHODS

Subjects were enrollees of three health plans who had all clinical measurements (blood pressure, fasting plasma glucose, body mass index, triglycerides, and high-density lipoprotein cholesterol) necessary to determine metabolic syndrome risk factors over the 2-year study period (n = 170,648). We used clinical values, International Classification of Diseases, Ninth Revision (ICD-9) diagnoses, and medication dispensings to identify risk factors. We report unadjusted mean annual utilization and modeled mean annual costs adjusting for age, sex, and co-morbidity.

RESULTS

Subjects with metabolic syndrome (n = 98,091) had higher utilization and costs compared to subjects with no metabolic syndrome (n = 72,557) overall, and when stratified by diabetes (P < 0.001). Average annual total costs between subjects with metabolic syndrome versus no metabolic syndrome differed by a magnitude of 1.6 overall ($5,732 vs. $3,581), and a magnitude of 1.3 when stratified by diabetes (diabetes, $7,896 vs. $6,038; no diabetes, $4,476 vs. $3,422). Overall, total costs increased by an average of 24% per additional risk factor (P < 0.001). Costs and utilization differed by risk factor clusters, but the more prevalent clusters were not necessarily the most costly. Costs for subjects with diabetes plus weight risk, dyslipidemia, and hypertension were almost double the costs for subjects with prediabetes plus similar risk factors ($8,067 vs. $4,638).

CONCLUSIONS

Metabolic syndrome, number of risk factors, and specific combinations of risk factors are markers for high utilization and costs among patients receiving medical care. Diabetes and certain risk clusters are major drivers of utilization and costs.

Assigning resources to health care use for health services research: options and consequences

AIMS

Our goals are 3-fold: (1) to review the leading options for assigning resource coefficients to health services utilization; (2) to discuss the relative advantages of each option; and (3) to provide examples where the research question had marked implications for the choice of which resource measure to employ.

METHODS

Three approaches have been used to establish relative resource weights in health services research: (a) direct estimation of production costs through microcosting or step down allocation methods; (b) macrocosting/regression analysis; and (c) standardized resource assignment. We describe each of these methods and provide examples of how the study question drove the choice of resource-use measure.

FINDINGS

All empirical resource-intensity weighting systems contain distortions that limit their universal application. Hence, users must select the weighting system that matches the needs of their specific analysis. All systems require significant data resources and data processing. However, inattention to the distortions contained in a complex resource weighting system may undermine the validity and generalizability of an economic evaluation.

CONCLUSIONS

Direct estimation of production costs are useful for empirical analyses, but they contain distortions that undermine optimal resource allocation decisions. Researchers must ensure that the data being used meets both the study design and the question being addressed. They also should ensure that the choice of resource measure is the best fit for the analysis. IMPLICATIONS FOR RESEARCH AND POLICY: Researchers should consider which of the available measures is the most appropriate for the question being addressed rather than take "cost " or utilization as a variable over which they have no control.

Changing the Conversation—The Occupational Health Nurse's Role in Integrated HS3™

Occupational health nurses have the skills and knowledge to provide a holistic perspective in advancing their company's triple bottom line, healthy people, healthy planet, and healthy profits. The HS3™ model provides a road map for integrating health, safety, sustainability, and stewardship, all of which directly impact every company's triple bottom line. Occupational health nurses can use the HS3™ model to promote healthy lifestyles, reduce risk and injuries, protect the natural environment, and improve resource alignment. Occupational health nurses have a unique opportunity to demonstrate the value they bring to their employers using synergistic HS3™ planning that cost-effectively finks work injury management, health promotion, environmental protection, safety training and surveillance, and regulatory compliance. Implementing the HS3™ model requires occupational health nurses to be innovators who can change the conversation.

Costs of severely ill members and specialty medication use in a commercially insured population

This study examines the overall profile and costs associated with severely ill commercially insured people. We found severely ill members to have the highest costs, from both the insurer and member perspective. Even for the most costly members where specialty medication use was highest, biologics represented less than one-third of the pharmacy spending and 6.6 percent of overall spending. Out-of-pocket spending rose dramatically when medications were paid for under the pharmacy benefit rather than the medical benefit. The advantages of paying for specialty medications under the pharmacy benefit should be evaluated in conjunction with the potential consequences of increased out-of-pocket burden.

Patient use of secure electronic messaging within a shared medical record: a cross-sectional study

BACKGROUND

Most patients would like to be able to exchange electronic messages with personal physicians. Few patients and providers are exchanging electronic communications.

OBJECTIVE

To evaluate patient characteristics associated with the use of secure electronic messaging between patients and health care providers.

DESIGN, SETTING, AND PATIENTS

Cross-sectional cohort study of enrollees over 18 years of age who were enrolled in an integrated delivery system in 2005.

MEASUREMENTS AND MAIN RESULTS

Among eligible enrollees, 14% (25,075) exchanged one or more secure messages with a primary or specialty care provider between January 1, 2004 and March 31, 2005. Higher secure messaging use by enrollees was associated with female gender (OR, 1.15; 95% CI, 1.10-1.19), greater overall morbidity (OR, 5.64; 95% CI, 5.07-6.28, comparing high or very high to very low overall morbidity), and the primary care provider's use of secure messaging with other patients (OR, 1.94; 95% CI, 1.67-2.26, comparing 20-50% vs. <or=10% encounters through secure messaging). Less secure messaging use was associated with enrollee age over 65 years (OR, 0.65; CI, 0.59-0.71) and Medicaid insurance vs. commercial insurance (OR, 0.81; 95% CI, 0.68-0.96).

CONCLUSIONS

In this integrated group practice, use of patient-provider secure messaging varied according to individual patient clinical and sociodemographic characteristics. Future studies should clarify variation in the use of electronic patient-provider messaging and its impact on the quality and cost of care received.

The Charlson comorbidity index is adapted to predict costs of chronic disease in primary care patients

OBJECTIVE

(1) To determine chronic illness costs for large cohort of primary care patients, (2) to develop prospective model predicting total costs over one year, using demographic and clinical information including widely used comorbidity index.

STUDY DESIGN AND SETTING

Data including diagnostic, medication, and resource utilization were obtained for 5,861 patients from practice-based computer system over a 1-year period beginning December 1, 1993, for retrospective analysis. Hospital cost data were obtained from hospital cost accounting system.

RESULTS

Average annual per patient cost was $2,655. Older patients and those with Medicare or Medicaid had higher costs. Hospital costs were $1,558, accounting for 58.7% of total costs. In the predictive model, individuals with higher comorbidity incurred exponentially higher annual costs, from $4,317 with comorbidity score of two, to $5,986 with score of three, to $13,326 with scores greater than seven. To use an adapted comorbidity index to predict total yearly costs, four conditions should be added to the index: hypertension, depression, and use of warfarin with a weight of one, skin ulcers/cellulitis, a weight of two.

CONCLUSION

The adapted comorbidity index can be used to predict resource utilization. Predictive models may help to identify targets for reducing high costs, by prospectively identifying those at high risk.

Improving care through health economics analyses: cost of illness and headache

The impact of headache disorders is a problem of enormous proportions, both for individual and society. The medical literature tried to assess its effects on individuals, by examining prevalence, distribution, attack frequency and duration, and headache-related disability, as well as effects on society, looking at the socio-economic burden of headache disorders [Rasmussen (Cephalalgia 19:20-23, 1999)]; [Lanteri-Minet et al. (Pain 102:143-149, 2003)]. The issue of costs represents an important problem too, concerning both direct and indirect costs. Direct costs concern mainly expenses for drugs. Migraine has a considerable impact on functional capacity, resulting in disrupted work and social activities: many migraineurs do not seek medical attention because they have not been accurately diagnosed by a physician or do not use prescribed medication [Solomon and Price (Pharmacoeconomics 11:1-10, 1997)]. Indirect costs associated with reduced productivity represent a substantial proportion of the total cost of migraine as well. Migraine has a major impact on the working sector of the population, and therefore, determining the indirect costs outweighs the direct costs. This study will explain the notion of cost of illness, examining how it could be applied in such a framework. Then, an overview of the studies aimed at measuring direct and indirect costs of migraine and headache disorders will be carried out, later shifting on to the relationship between costs and quality of life for people affected by headache disorders. Finally, a brief review on advantages of new pharmaceuticals and preventive treatments for migraine for patients and society will outline improvements in the context of cost-effectiveness and cost-utility analysis.

Treated prevalence and incidence of dementia among National Health Insurance enrollees in Taiwan, 1996-2003

The National Health Insurance database to determine the treated prevalence and incidence of dementia in Taiwan was used in this study. A population-based random sample of 22 118 subjects aged 65 or older was obtained as a dynamic cohort. Those study subjects who had filed at least one service claim from 1996 to 2003 for either outpatient care or inpatient care with a principal diagnosis of dementia were identified. The annual treated prevalence increased from 0.71% to 1.92% from 1996 to 2003. The annual treated incidence rates were around 0.76% to 1.04% per year from 1997 to 2003. The annual treated incidence rates for the 5-year age groups, from 65 to 90 years and older, were 0.44%, 0.65%, 0.98%, 1.46%, 1.81%, and 1.80%, respectively. Both the treated prevalence and incidence rates of dementia in National Health Insurance were lower than those of community studies.

Cost of care for elderly cancer patients in the United States

BACKGROUND

Timely estimates of the costs of care for cancer patients are an important element in the formulation of national cancer programs and policies. We estimated net costs of care for elderly cancer patients in the United States for the 18 most prevalent cancers and for all other tumor sites combined.

METHODS

We used Surveillance, Epidemiology, and End Results-Medicare files to identify 718,907 cancer patients and 1,623,651 noncancer control subjects. Within each tumor site, noncancer control subjects were matched to patients by sex, age group, geographic location, and phase of care (ie, initial, continuing, and last year of life). Costs of care were estimated for each phase by use of Medicare claims data from January 1, 1999, through December 31, 2003. Per-patient net costs of care were applied to the 5-year survival of cancer patients by phase of care to estimate 5-year costs of care and extrapolated to the elderly US Medicare population diagnosed with cancer in 2004.

RESULTS

Across tumor sites, mean net costs of care were highest in the initial and last year of life phases of care and lowest in the continuing phase. Mean 5-year net costs varied widely, from less than $20,000 for patients with breast cancer or melanoma of the skin to more than $40,000 for patients with brain or other nervous system, esophageal, gastric, or ovarian cancers or lymphoma. For elderly cancer patients diagnosed in 2004, aggregate 5-year net costs of care to Medicare were estimated to be approximately $21.1 billion. Costs to Medicare were highest for lung, colorectal, and prostate cancers, reflecting underlying incidence, stage distribution at diagnosis, survival, and phase-specific costs for these tumor sites.

CONCLUSIONS

The costs of cancer care to Medicare are substantial and vary by tumor site, phase of care, stage at diagnosis, and survival.

Chronic nonmalignant pain: a challenge for patients and clinicians

Chronic pain is widely regarded as a condition that is triggered by various factors, including physical, socio-cultural and psychological deficiencies (that is, maladaptive beliefs). These factors are important in the development and maintenance of this unpleasant experience, which consequently requires a biopsychosocial treatment approach. Pain is a multifaceted sense, the perception of which is personal. Pain also depends on various circumstances, and therefore represents a challenge for the patient, as well for the treating physicians. Patients who suffer from long-lasting pain with a predominantly psychosocial component should be referred to specialized pain clinics for further diagnostic assessment and possible allocation to multidisciplinary pain programs. High-quality randomized controlled trials indicate that multidisciplinary pain programs represent the best therapeutic option for the management of patients with complaints associated with complex chronic pain. The prevalence and the costs--both direct and indirect--that are attributed to chronic pain are increasing; however, not enough is being done to sufficiently and effectively treat chronic pain. There is, therefore, a need for well-designed, interdisciplinary, internationally comparable, and widely distributed pain programs, both in outpatient and inpatient settings, to contribute to the prevention of some future pain diseases.

Intimate partner violence and health care costs and utilization for children living in the home

OBJECTIVE

The goal was to determine whether differences in health care costs and utilization exist for children whose mothers experienced intimate partner violence versus those who did not.

METHODS

A longitudinal cohort study was performed in an integrated health care delivery organization with 760 children of mothers with no history of intimate partner violence and 631 children of mothers with a history of intimate partner violence since age 18. Health care utilization and costs for children before, during, and after intimate partner violence exposure were compared with utilization and costs for children with nonabused mothers.

RESULTS

Health care utilization and health care costs were higher in most categories of care for children of mothers with a history of intimate partner violence, with significantly higher values for mental health services, primary care visits, primary care costs, and laboratory costs. Children of mothers with a history of intimate partner violence that ended before the child was born had significantly greater utilization of mental health, primary care, specialty care, and pharmacy services than did children of mothers who reported no intimate partner violence. Children exposed directly to intimate partner violence (after birth) had greater emergency department and primary care use during the intimate partner violence and were 3 times as likely to use mental health services after the intimate partner violence ended.

CONCLUSIONS

Children whose mothers experienced intimate partner violence have higher health care utilization and costs, even if their mothers' abuse stopped before they were born. Screening of women for intimate partner violence should be a routine part of their health care, and interventions for both the women and their children are likely necessary to minimize the effects of intimate partner violence in the family.

Costs of cancer care in the USA: a descriptive review

Although many studies assessing the cost of cancer care have been conducted in the US, to date, these studies and the underlying methods used to estimate costs have not been reviewed systematically. We conducted a descriptive review of the published literature on the cost of cancer care in the US, and identified 60 papers published between 1995 and 2006 pertinent to our study. We found heterogeneity across the studies in terms of the settings, populations studied, measurement of costs, and study methods. We also identified limitations in the generalizability of findings, the misclassification of patient groups and costs, and concerns with study methods. Among studies that reported costs of cancer care in multiple phases of care and for multiple tumor sites, costs were generally highest in the initial year following diagnosis and the last year of life, and lower in the continuing phase (i.e. the period between the initial and last year of life phases), following a 'u-shaped' curve. Within phase of care, costs for lung and colorectal cancer care were generally higher than those for breast and prostate cancer care, however, the long-term or lifetime costs for each type of cancer were more similar, reflecting the differences in survival and costs in each phase between the different disease types.

Can disease management target patients most likely to generate high costs? The impact of comorbidity

CONTEXT

Disease management programs are increasingly used to manage costs of patients with chronic disease.

OBJECTIVE

We sought to examine the clinical characteristics and measure the health care expenditures of patients most likely to be targeted by disease management programs.

DESIGN

Retrospective analysis of prospectively obtained data.

SETTING

A general medicine practice with both faculty and residents at an urban academic medical center.

PARTICIPANTS

Five thousand eight hundred sixty-one patients enrolled in the practice for at least 1 year.

MAIN OUTCOMES

Annual cost of diseases targeted by disease management.

MEASUREMENTS

Patients' clinical and demographic information were collected from a computer system used to manage patients. Data included diagnostic information, medications, and resource usage over 1 year. We looked at 10 common diseases targeted by disease management programs.

RESULTS

Unadjusted annual median costs for chronic diseases ranged between $1,100 and $1,500. Congestive heart failure ($1,500), stroke ($1,500), diabetes ($1,500), and cancer ($1,400) were the most expensive. As comorbidity increased, annual adjusted costs increased exponentially. Those with comorbidity scores of 2 or more accounted for 26% of the population but 50% of the overall costs.

CONCLUSIONS

Costs for individual chronic conditions vary within a relatively narrow range. However, the costs for patients with multiple coexisting medical conditions increase rapidly. Reducing health care costs will require focusing on patients with multiple comorbid diseases, not just single diseases. The overwhelming impact of comorbidity on costs raises significant concerns about the potential ability of disease management programs to limit the costs of care.

Healthcare utilization and costs for women with a history of intimate partner violence

OBJECTIVE

To determine the healthcare utilization and medical care costs of women with a history of intimate partner violence (IPV) compared to women without a history of IPV.

DESIGN

Longitudinal cohort study.

SETTING

Mixed-model health maintenance organization.

PARTICIPANTS

Over 3000 (3333) women aged 18 to 64 years with > or = 3 year's cumulative enrollment prior to the survey, at least 1 year of which was after the 18th birthday.

MAIN EXPOSURE

IPV since age 18 as determined from responses to telephone interview using questions from the Behavioral Risk Factor Surveillance System and also the Women's Experience with Battering Scale.

OUTCOME MEASURES

Healthcare utilization and costs (from automated data) during the time that IPV occurred and following its cessation, compared to healthcare utilization for women who did not report IPV since age 18.

RESULTS

A total of 1546 women reported IPV in their lifetime; at the time of interview, IPV had ceased in 87% of women, on average 16.0 years prior to interview. Healthcare utilization was higher for all categories of service during IPV compared to women without IPV, and decreased over time after cessation of IPV. However, healthcare utilization was still 20% higher 5 years after women's abuse ceased compared to women without IPV. Adjusted annual total healthcare costs were 19% higher in women with a history of IPV (amounting to $439 annually) compared to women without IPV. Based on prevalence for IPV of 44%, the excess costs due to IPV are approximately $19.3 million per year for every 100,000 women enrollees aged 18-64.

CONCLUSIONS

Women with a history of IPV had significantly higher healthcare utilization and costs, continuing long after IPV ended. Given its high prevalence, IPV has a major impact on medical care resource utilization and efforts to prevent its occurrence and consequences are clearly indicated.

Changes in health care costs before and after smoking cessation

Previous research on health care costs among former smokers suggests that quitters incur greater health care costs for up to 4 years after cessation compared with continuing smokers. However, little is known about the relationship between health care costs and utilization in the periods before as well as after cessation. The present study used a retrospective cohort design with automated health plan and primary data to examine the health care costs and clinical experiences before and after smoking cessation among former smokers compared with a sample of continuing smokers. Subjects were a random sample of adults (aged 25 and older) whose smoking status was identified by a physician during a primary care visit to the Group Health Cooperative (GHC), a nonprofit, integrated health care delivery system in western Washington state. Total direct health care costs among former smokers began to rise in the quarter prior to cessation and were significantly greater (p < .001) than those of continuing smokers in the quarter immediately following cessation. This difference dissipated within one quarter following cessation. We replicated the postquit cost spike among former smokers found by other research and showed that this spike dissipated within the first year postquit. Smoking cessation did not result in sustained cost increases among former smokers.
