RESUMO
Importance: Palliative care consultations in intensive care units (ICUs) are increasingly prompted by clinical characteristics associated with mortality or resource utilization. However, it is not known whether these triggers reflect actual palliative care needs. Objective: To compare unmet needs by clinical palliative care trigger status (present vs absent). Design, Setting, and Participants: This prospective cohort study was conducted in 6 adult medical and surgical ICUs in academic and community hospitals in North Carolina between January 2019 and September 2020. Participants were consecutive patients receiving mechanical ventilation and their family members. Exposure: Presence of any of 9 common clinical palliative care triggers. Main Outcomes and Measures: The primary outcome was the Needs at the End-of-Life Screening Tool (NEST) score (range, 0-130, with higher scores reflecting greater need), which was completed after 3 days of ICU care. Trigger status performance in identifying serious need (NEST score ≥30) was assessed using sensitivity, specificity, positive and negative likelihood ratios, and C statistics. Results: Surveys were completed by 257 of 360 family members of patients (71.4% of the potentially eligible patient-family member dyads approached) with a median age of 54.0 years (IQR, 44-62 years); 197 family members (76.7%) were female, and 83 (32.3%) were Black. The median age of patients was 58.0 years (IQR, 46-68 years); 126 patients (49.0%) were female, and 88 (33.5%) were Black. There was no difference in median NEST score between participants with a trigger present (45%) and those with a trigger absent (55%) (21.0; IQR, 12.0-37.0 vs 22.5; IQR, 12.0-39.0; P = .52). Trigger presence was associated with poor sensitivity (45%; 95% CI, 34%-55%), specificity (55%; 95% CI, 48%-63%), positive likelihood ratio (1.0; 95% CI, 0.7-1.3), negative likelihood ratio (1.0; 95% CI, 0.8-1.2), and C statistic (0.50; 95% CI, 0.44-0.57). Conclusions and Relevance: In this cohort study, clinical palliative care trigger status was not associated with palliative care needs and no better than chance at identifying the most serious needs, which raises questions about an increasingly common clinical practice. Focusing care delivery on directly measured needs may represent a more person-centered alternative.

Purpose: Research suggests that providers contribute to racial disparities in health outcomes. Identifying modifiable provider perspectives that are associated with decreased racial disparities will help in the design of effective educational interventions for providers. Methods: This cross-sectional study investigated the association between primary care provider (PCP) perspectives on race and racial disparities with patient outcomes. Results: Study participants included 40 PCPs (70% White, 30% racial minority) caring for 55 patients (45% White, 55% Black) with type 2 diabetes mellitus. Associations of provider perspectives on race and racial disparities with patient variables (Interpersonal Processes of Care [IPC] Survey, which measures patient's ratings of their provider's interpersonal skills; medication adherence; glycemic control) were measured using Spearman correlation coefficients. Results suggest that Black patients of providers who reported greater skill in caring for Black patients had more positive perceptions of care in three of four IPC subdomains (Spearman correlation coefficients of -0.43, 0.44, 0.46, all with p<0.05); however, Black patients of providers who believe that racial disparities are highly prevalent had more negative perceptions of care in three of four IPC subdomains (Spearman correlation coefficients of 0.38, -0.53, -0.51, all with p<0.05). These same provider characteristics had no correlation with outcomes of medication adherence and hemoglobin A1c (HbA1c) or among White patients. Conclusion: Findings suggest that Black patients of providers who felt better equipped to take care of Black patients had a better experience. Therefore, educational interventions for providers may be most effective if they focus on skill development rather than increasing awareness about racial disparities alone.
RESUMO
Purpose: We explored the association between perception of care, as measured by the Interpersonal Processes of Care (IPC) survey, and patient-level factors, including (1) Trust in physicians; (2) Perceived empathy; (3) Stereotype threat; (4) Perceived everyday discrimination; and (5) Self-Reported Health. Methods: Fifty participants from diverse racial backgrounds and education levels were surveyed. We examined the associations between the five patient-level factors and each subdomain of the IPC using multiple linear regression. We added a race interaction term to assess whether associations between IPC subdomains and predictors differed by race. We tested for correlation among factors found to be significantly associated with the IPC. Results: In adjusted analyses, trust in the physician, perceived empathy from the provider, and perceived everyday discrimination were significantly associated with most subdomains of the IPC. There was no significant race interaction. Conclusion: This exploratory study suggests that empathy, trust, and perceived everyday discrimination are significantly linked to patient perception of quality care, which are linked to clinical outcomes. Results present modifiable factors that may potentially improve patient care. Practice Implications: Increased efforts to improve clinician communication of empathy and general communication skill may have a positive effect on quality of care.
RESUMO
BACKGROUND: Short-term health care costs following completion of health risk assessments and coaching programs in the VA have not been assessed. OBJECTIVE: To compare VA health care expenditures among veterans who participated in a behavioral intervention trial that randomized patients to complete a HRA followed by health coaching (HRA + coaching) or to complete the HRA without coaching (HRA-alone). DESIGN: Four-hundred seventeen veterans at three Veterans Affairs (VA) Medical Centers or Clinics were randomized to HRA + coaching or HRA-alone. Veterans randomized to HRA-alone (n = 209) were encouraged to discuss HRA results with their primary care team, while veterans randomized to HRA + coaching (n = 208) received two brief telephone-delivered health coaching calls. PARTICIPANTS: We included 411 veterans with available cost data. MAIN MEASURES: Total VA health expenditures 6 months following trial enrollment were estimated using a generalized linear model with a gamma distribution and log link function. In exploratory analysis, model-based recursive partitioning was used to determine whether the intervention effect on short-term costs differed among any patient subgroups. KEY RESULTS: Most participants were male (85%); mean age was 56, and mean body mass index was 34. From the generalized linear model, 6-month estimated mean total VA expenditures were similar ($8665 for HRA + coaching vs $9900 for HRA-alone, p = 0.25). In exploratory subgroup analysis, among unemployed veterans with good sleep and fair or poor perceived health, mean observed expenditures in the HRA + coaching group were higher than in the HRA-alone group ($12,814 vs $7971). Among unemployed veterans with good sleep and good general health, mean observed expenditures in the HRA + coaching group were lower than in the HRA-alone group ($5082 vs $11,612). CONCLUSIONS: Compared to completing and receiving HRA results, working with health coaches to set actionable health behavior change goals following HRA completion did not reduce short-term health expenditures. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT01828567.

Importance: Bariatric surgery has been associated with improvements in health in patients with severe obesity; however, it is unclear whether these health benefits translate into lower health care expenditures. Objective: To examine 10-year health care expenditures in a large, multisite retrospective cohort study of veterans with severe obesity who did and did not undergo bariatric surgery. Design, Setting, and Participants: A total of 9954 veterans with severe obesity between January 1, 2000, and September 30, 2011, were identified from veterans affairs (VA) electronic health records. Of those, 2498 veterans who underwent bariatric surgery were allocated to the surgery cohort. Sequential stratification was used to match each patient in the surgery cohort with up to 3 patients who had not undergone bariatric surgery but were of the same sex, race/ethnicity, diabetes status, and VA regional network and were closest in age, body mass index (calculated as weight in kilograms divided by height in meters squared), and comorbidities. A total of 7456 patients were identified and allocated to the nonsurgery (control) cohort. The VA health care expenditures among the surgery and nonsurgery cohorts were estimated using regression models. Data were analyzed from July to August 2018 and in April 2019. Interventions: The bariatric surgical procedures (n = 2498) included in this study were Roux-en-Y gastric bypass (1842 [73.7%]), sleeve gastrectomy (381 [15.3%]), adjustable gastric banding (249 [10.0%]), and other procedures (26 [1.0%]). Main Outcomes and Measures: The study measured total, outpatient, inpatient, and outpatient pharmacy expenditures from 3 years before surgery to 10 years after surgery, excluding expenditures associated with the initial bariatric surgical procedure. Results: Among 9954 veterans with severe obesity, 7387 (74.2%) were men; the mean (SD) age was 52.3 (8.8) years for the surgery cohort and 52.5 (8.7) years for the nonsurgery cohort. Mean total expenditures for the surgery cohort were $5093 (95% CI, $4811-$5391) at 7 to 12 months before surgery, which increased to $7448 (95% CI, $6989-$7936) at 6 months after surgery. Postsurgical expenditures decreased to $6692 (95% CI, $6197-$7226) at 5 years after surgery, followed by a gradual increase to $8495 (95% CI, $7609-$9484) at 10 years after surgery. Total expenditures were higher in the surgery cohort than in the nonsurgery cohort during the 3 years before surgery and in the first 2 years after surgery. The expenditures of the 2 cohorts converged 5 to 10 years after surgery. Outpatient pharmacy expenditures were significantly lower among the surgery cohort in all years of follow-up ($509 lower at 3 years before surgery and $461 lower at 7 to 12 months before surgery), but these cost reductions were offset by higher inpatient and outpatient (nonpharmacy) expenditures. Conclusions and Relevance: In this cohort study of 9954 predominantly older male veterans with severe obesity, total health care expenditures increased immediately after patients underwent bariatric surgery but converged with those of patients who had not undergone surgery at 10 years after surgery. This finding suggests that the value of bariatric surgery lies primarily in its associations with improvements in health and not in its potential to decrease health care costs.

This study aimed to examine the early impact of the Program of Comprehensive Assistance for Family Caregivers (PCAFC) on Veteran health care utilization and costs. A pre-post cohort design including a nonequivalent control group was used to understand how Veterans' use of Veteran Affairs health care and total health care costs changed in 6-month intervals up to 3 years after PCAFC enrollment. The control group was an inverse probability of treatment weighted sample of Veterans whose caregivers applied for, but were not accepted into, PCAFC. Veterans in PCAFC had similar acute care utilization postenrollment when compared with those in the control group, but significantly greater primary, specialty, and mental health outpatient care use at least 30, and up to 36, months postenrollment. Estimated total health care costs for PCAFC Veterans were $1,500 to $3,400 higher per 6-month interval than for control group Veterans. PCAFC may have increased Veterans' access to care.

OBJECTIVE: To compare different strategies for analyzing longitudinal expenditure data that have a point mass at $0. We provide guidance on parameter interpretation, research questions, and model selection. DATA SOURCES, STUDY DESIGN, AND DATA COLLECTION: One-part models, uncorrelated two-part models, correlated conditional two-part (CTP) models, and correlated marginalized two-part (MTP) models have been proposed for longitudinal expenditures that often exhibit a large proportion of zeros and a distribution of continuous, highly right-skewed positive values. Guidance on implementing and interpreting each of these model is illustrated with an example of longitudinal (2000-2003) specialty care expenditures of veterans with hypertension, drawn from Veterans Administration data. PRINCIPAL FINDINGS: The four strategies answer different research questions, are appropriate for different structures of data, and provide different results. If there is a point mass at $0, then the MTP model may be most useful if the primary interest is in mean expenditures of the entire population. A CTP model may be most useful if the primary interest is in the level of expenditures conditional on them being incurred. CONCLUSIONS: Researchers should consider which modeling strategy for longitudinal expenditure outcomes is both consistent with research aims and appropriate for the data at hand.

BACKGROUND: Weight regain after successful weight loss interventions is common. OBJECTIVE: To establish the efficacy of a weight loss maintenance program compared with usual care in obese adults. DESIGN: 2-group, parallel, randomized trial stratified by initial weight loss (<10 kg vs. ≥10 kg), conducted from 20 August 2012 to 18 December 2015. Outcome assessors were blinded to treatment assignment. (ClinicalTrials.gov: NCT01357551). SETTING: 3 primary care clinics at the Veterans Affairs Medical Center in Durham and Raleigh, North Carolina. PATIENTS: Obese outpatients (body mass index ≥30 kg/m2) who lost 4 kg or more of body weight during a 16-week, group-based weight loss program. INTERVENTION: The maintenance intervention, delivered primarily by telephone, addressed satisfaction with outcomes, relapse-prevention planning, self-monitoring, and social support. Usual care involved no contact except for study measurements. MEASUREMENTS: Primary outcome was mean weight regain at week 56. Secondary outcomes included self-reported caloric intake, walking, and moderate physical activity. RESULTS: Of 504 patients in the initial program, 222 lost at least 4 kg of body weight and were randomly assigned to maintenance (n = 110) or usual care (n = 112). Retention was 85%. Most patients were middle-aged white men. Mean weight loss during initiation was 7.2 kg (SD, 3.1); mean weight at randomization was 103.6 kg (SD, 20.4). Estimated mean weight regain was statistically significantly lower in the intervention (0.75 kg) than the usual care (2.36 kg) group (estimated mean difference, 1.60 kg [95% CI, 0.07 to 3.13 kg]; P = 0.040). No statistically significant differences in secondary outcomes were seen at 56 weeks. No adverse events directly attributable to the intervention were observed. LIMITATIONS: Results may not generalize to other settings or populations. Dietary intake and physical activity were self-reported. Duration was limited to 56 weeks. CONCLUSION: An intervention focused on maintenance-specific strategies and delivered in a resource-conserving way modestly slowed the rate of weight regain in obese adults.

BACKGROUND: Compared with men, women have poorer lipid control. Although potential causes of this disparity have been explored, it is unknown whether patient-centered factors such as satisfaction and confidence contribute. We evaluated (1) whether satisfaction with lipid control and confidence in ability to improve it vary by gender and (2) whether sociodemographic characteristics modify the association. MATERIALS AND METHODS: We evaluated baseline survey responses from the Cardiovascular Intervention Improvement Telemedicine Study, including self-rated satisfaction with cholesterol levels and confidence in controlling cholesterol. Participants had poorly controlled hypertension and/or hypercholesterolemia. RESULTS: A total of 428 veterans (15% women) participated. Compared with men, women had higher low-density lipoprotein values at 141.2 versus 121.7 mg/dL, respectively (p < 0.05), higher health literacy, and were less likely to have someone to help track their medications (all p < 0.05). In an adjusted model, women were less satisfied with their cholesterol levels than men with estimated mean scores of 4.3 versus 5.6 on a 1-10 Likert scale (p < 0.05). There was no significant difference in confidence by gender. Participants with support for tracking medications reported higher confidence levels than those without, estimated mean 7.8 versus 7.2 (p < 0.05). CONCLUSIONS: Women veterans at high risk for cardiovascular disease were less satisfied with their lipid control than men; however, confidence in ability to improve lipid levels was similar. Veterans without someone to help to track medications were less confident, and women were less likely to have this type of social support. Lack of social support for medication tracking may be a factor in lingering gender-based disparities in hyperlipidemia.

INTRODUCTION: Smoking is the most preventable cause of morbidity and mortality in U.S. veterans. Rural veterans in particular have elevated risk for smoking and smoking-related illness. However, these veterans underutilize smoking cessation treatment, which suggests that interventions for rural veterans should optimize efficacy and reach. OBJECTIVE: The primary goal of the current study is to evaluate the effectiveness of an intervention that combines evidenced based treatment for smoking cessation with smart-phone based, portable contingency management on smoking rates compared to a contact control intervention in a randomized controlled trial among rural Veteran smokers. Specifically, Veterans will be randomized to receive Abstinence Reinforcement Therapy (ART) which combines evidenced based cognitive-behavioral telephone counseling (TC), a tele-medicine clinic for access to nicotine replacement (NRT), and mobile contingency management (mCM) or a control condition (i.e., TC and NRT alone) that will provide controls for therapist, medication, time and attention effects. METHODS: Smokers were identified using VHA electronic medical records and recruited proactively via telephone. Participants (N=310) are randomized to either ART or a best practice control consisting of telephone counseling and telemedicine. Participating patients will be surveyed at 3-months, 6-months and 12-months post-randomization. The primary outcome measure is self-reported and biochemically validated prolonged abstinence at 6-month follow-up. DISCUSSION: This trial is designed to test the relative effectiveness of ART compared to a telehealth-only comparison group. Dissemination of this mHealth intervention for veterans in a variety of settings would be warranted if ART improves smoking outcomes for rural veterans and is cost-effective.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of mortality for U.S. women. Racial minorities are a particularly vulnerable population. The increasing female veteran population has an higher prevalence of certain cardiovascular risk factors compared with non-veteran women; however, little is known about gender and racial differences in cardiovascular risk factor control among veterans. METHODS: We used analysis of variance, adjusting for age, to compare gender and racial differences in three risk factors that predispose to CVD (diabetes, hypertension, and hyperlipidemia) in a cohort of high-risk veterans eligible for enrollment in a clinical trial, including 23,955 men and 1,010 women. FINDINGS: Low-density lipoprotein (LDL) values were higher in women veterans than men with age-adjusted estimated mean values of 111.7 versus 97.6 mg/dL (p < .01). Blood pressures (BPs) were higher among African-American than White female veterans with age-adjusted estimated mean systolic BPs of 136.3 versus 133.5 mmHg, respectively (p < .01), and diastolic BPs of 82.4 versus 78.9 mmHg (p < .01). African-American veterans with diabetes had worse BP, LDL values, and hemoglobin A1c levels, although the differences were only significant among men. CONCLUSIONS: Female veterans have higher LDL cholesterol levels than male veterans and African-American veterans have higher BP, LDL cholesterol, and A1c levels than Whites after adjusting for age. Further examination of CVD gender and racial disparities in this population may help to develop targeted treatments and strategies applicable to the general population.

BACKGROUND: Obesity is a significant public health problem. Although various lifestyle approaches are effective for inducing significant weight loss, few effective behavioral weight maintenance strategies have been identified. It has been proposed that behavior maintenance is a distinct state that involves different psychological processes and behavioral skills than initial behavior change. Previously, we created a conceptual model that distinguishes behavior initiation from maintenance. This model was used to generate Maintenance After Initiation of Nutrition TrAINing (MAINTAIN), an intervention to enhance weight loss maintenance following initiation. The effectiveness of MAINTAIN is being evaluated in an ongoing trial, the rationale and procedures of which are reported herein. METHODS/DESIGN: Veterans aged ≤ 75 with body mass index ≥ 30 kg/m(2) participate in a 16-week, group-based weight loss program. Participants who lose ≥ 4 kg by the end of 16 weeks (target n = 230) are randomized 1:1 to receive (a) usual care for 56 weeks or (b) MAINTAIN, a theoretically-informed weight loss maintenance intervention for 40 weeks, followed by 16 weeks of no intervention contact. MAINTAIN involves 3 in-person group visits that transition to 8 individualized telephone calls with decreasing contact frequency. MAINTAIN focuses on satisfaction with outcomes, weight self-monitoring, relapse prevention, and social support. We hypothesize that, compared to usual care, MAINTAIN will result in at least 3.5 kg less regain and better relative levels of caloric intake and physical activity over 56 weeks, and that it will be cost-effective. DISCUSSION: If effective, MAINTAIN could serve as a model for redesigning existing weight loss programs. CLINICALTRIALSGOV IDENTIFIER: NCT01357551.

OBJECTIVES: To compare the prevalence and predictors of caregiver esteem and burden during two different stages of care recipients' illnesses-advanced chronic illness and the last year of life. DESIGN: Longitudinal, observational cohort study. SETTING: Community sample recruited from outpatient clinics at Duke University and Durham Veterans Affairs Medical Centers. PARTICIPANTS: Individuals with advanced cancer, congestive heart failure, or chronic obstructive pulmonary disease and their primary caregiver, retrospectively coded as chronic-illness (n = 62) or end-of-life (EOL; n = 62) care recipient-caregiver dyads. MEASUREMENTS: Caregiver experience was measured monthly using the Caregiver Reaction Assessment, which includes caregiver esteem and four domains of burden: schedule, health, family, and finances. RESULTS: During chronic illness and at the end of life, high caregiver esteem was almost universal (95%); more than 25% of the sample reported health, family, and financial burden. Schedule burden was the most prevalent form of burden; EOL caregivers (58%) experienced it more frequently than chronic-illness caregivers (32%). Caregiver esteem and all dimensions of burden were relatively stable over 1 year. Few factors were associated with burden. CONCLUSION: Caregiver experience is relatively stable over 1 year and similar in caregivers of individuals in the last year of life and those earlier in the course of chronic illness. Schedule burden stands out as most prevalent and variable among dimensions of experience. Because prevalence of burden is not specific to stage of illness and is relatively stable over time, multidisciplinary healthcare teams should assess caregiver burden and refer burdened caregivers to supportive resources early in the course of chronic illness.

BACKGROUND: Hypertension self-management has been shown to improve systolic blood pressure (BP) control, but longer-term economic and clinical impacts are unknown. The purpose of this article is to examine clinical and economic outcomes 18 months after completion of a hypertension self-management trial. METHODS AND RESULTS: This study is a follow-up analysis of an 18-month, 4-arm, hypertension self-management trial of 591 veterans with hypertension who were randomized to usual care or 1 of 3 interventions. Clinic-derived systolic blood pressure obtained before, during, and after the trial were estimated using linear mixed models. Inpatient admissions, outpatient expenditures, and total expenditures were estimated using generalized estimating equations. The 3 telephone-based interventions were nurse-administered health behavior promotion, provider-administered medication adjustments based on hypertension treatment guidelines, or a combination of both. Intervention calls were triggered by home BP values transmitted via telemonitoring devices. Clinical and economic outcomes were examined 12 months before, 18 months during, and 18 months after trial completion. Compared with usual care, patients randomized to the combined arm had greater improvement in proportion of BP control during and after the 18-month trial and estimated proportion of BP control improved 18 months after trial completion for patients in the behavioral and medication management arms. Among the patients with inadequate baseline BP control, estimated mean systolic BP was significantly lower in the combined arm as compared with usual care during and after the 18-month trial. Utilization and expenditure trends were similar for patients in all 4 arms. CONCLUSIONS: Behavioral and medication management can generate systolic BP improvements that are sustained 18 months after trial completion.

BACKGROUND: Clinicians have difficulty in identifying patients that are unlikely to adhere to hypertension self-management. Identifying non-adherence is essential to addressing suboptimal blood pressure control and high costs. OBJECTIVES: 1) To identify risk factors associated with non-adherence to three key self-management behaviors in patients with hypertension: proper medication use, diet, and exercise; 2) To evaluate the extent to which an instrument designed to identify the number of risk factors present for non-adherence to each of the three hypertension self-management behaviors would be associated with self-management non-adherence and blood pressure. DESIGN: Cross-sectional analysis of randomized trial data. PATIENTS: Six hundred and thirty-six primary care patients with hypertension. MEASUREMENTS: 1) Demographic, socioeconomic, psychosocial, and health belief-related factors; 2) measures of self-reported adherence to recommended medication use, diet recommendations, and exercise recommendations, all collected at baseline assessment; 3) systolic blood pressure (SBP) and diastolic blood pressure (DBP). RESULTS: We identified patient factors associated with measures of non-adherence to medications, diet, and exercise in hypertension. We then combined risk factors associated with ≥1 adherence measure into an instrument that generated three composite variables (medication, diet, and exercise composites), reflecting the number of risk factors present for non-adherence to the corresponding self-management behavior. These composite variables identified subgroups with higher likelihood of medication non-adherence, difficulty following diet recommendations, and difficulty following exercise recommendations. Composite variable levels representing the highest number of self-management non-adherence risk factors were associated with higher SBP and DBP. CONCLUSIONS: We identified factors associated with measures of non-adherence to recommended medication use, diet, and exercise in hypertension. We then developed an instrument that was associated with non-adherence to these self-management behaviors, as well as with blood pressure. With further study, this instrument has potential to improve identification of non-adherent patients with hypertension.

BACKGROUND: African Americans are significantly more likely than whites to have uncontrolled hypertension, contributing to significant disparities in cardiovascular disease and events. OBJECTIVE: The goal of this study was to examine whether there were differences in change in blood pressure (BP) for African American and non-Hispanic white patients in response to a medication management and tailored nurse-delivered telephone behavioral program. PARTICIPANTS: Five hundred and seventy-three patients (284 African American and 289 non-Hispanic white) primary care patients who participated in the Hypertension Intervention Nurse Telemedicine Study (HINTS) clinical trial. INTERVENTIONS: Study arms included: 1) nurse-administered, physician-directed medication management intervention, utilizing a validated clinical decision support system; 2) nurse-administered, behavioral management intervention; 3) combined behavioral management and medication management intervention; and 4) usual care. All interventions were activated based on poorly controlled home BP values. MAIN MEASURES: Post-hoc analysis of change in systolic and diastolic blood pressure. General linear models (PROC MIXED in SAS, version 9.2) were used to estimate predicted means at 6-month, 12-month, and 18-month time points, by intervention arm and race subgroups (separate models for systolic and diastolic blood pressure). KEY RESULTS: Improvement in mean systolic blood pressure post-baseline was greater for African American patients in the combined intervention, compared to African American patients in usual care, at 12 months (6.6 mmHg; 95 % CI: -12.5, -0.7; p=0.03) and at 18 months (9.7 mmHg; -16.0, -3.4; p=0.003). At 18 months, mean diastolic BP was 4.8 mmHg lower (95 % CI: -8.5, -1.0; p=0.01) among African American patients in the combined intervention arm, compared to African American patients in usual care. There were no analogous differences for non-Hispanic white patients. CONCLUSIONS: The combination of home BP monitoring, remote medication management, and telephone tailored behavioral self-management appears to be particularly effective for improving BP among African Americans. The effect was not seen among non-Hispanic white patients.

CONTEXT: Three important causes of death in the U.S. (cancer, congestive heart failure, and chronic obstructive pulmonary disease) are preceded by long periods of declining health; often, family members provide most care for individuals who are living with serious illnesses and are at risk for impaired well-being. OBJECTIVES: To expand understanding of caregiver burden and psychosocial-spiritual outcomes among understudied groups of caregivers-cancer, congestive heart failure, and chronic obstructive pulmonary disease caregivers-by including differences by disease in a diverse population. METHODS: The present study included 139 caregiver/patient dyads. Independent variables included patient diagnosis and function; and caregiver demographics, and social and coping resources. Cross-sectional analyses examined distributions of these independent variables between diagnoses, and logistic regression examined correlates of caregiver burden, anxiety, depressive symptoms, and spiritual well-being. RESULTS: There were significant differences in patient functioning and caregiver demographics and socioeconomic status between diagnosis groups but few differences in caregiver burden or psychosocial-spiritual outcomes by diagnosis. The most robust social resources indicator of caregiver burden was desire for more help from friends and family. Anxious preoccupation coping style was robustly associated with caregiver psychosocial-spiritual outcomes. CONCLUSION: Caregiver resources, not patient diagnosis or illness severity, are the primary correlates associated with caregiver burden. Additionally, caregiver burden is not disease specific to those examined here, but it is rather a relatively universal experience that may be buffered by social resources and successful coping styles.

BACKGROUND: Half of patients with hypertension have poor blood pressure (BP) control. Recent models for treating hypertension have integrated disease monitoring and telephone-based interventions delivered in patients' homes. This study evaluated the costs of the Hypertension Intervention Nurse Telemedicine Study (HINTS), aimed to improve BP control in veterans. METHODS: Eligible veterans were randomized to either usual care or 1 of 3 telephone-based intervention groups using home BP telemonitoring: (1) behavioral management, (2) medication management, or (3) combined. Intervention costs were derived from information collected during the trial. Direct medical costs (inpatient, outpatient, and outpatient pharmacy, including hypertension-specific pharmacy) at 18 months by group were calculated using Veterans Affairs (VA) Decision Support System data. Bootstrapped CIs were computed to compare intervention and medical costs between intervention groups and usual care. RESULTS: Patients receiving behavior or medication management showed significant gains in BP control at 12 months; there were no differences in BP control at 18 months. In subgroup analysis, patients with poor baseline BP control receiving combined intervention significantly improved BP at 12 and 18 months. In overall and subgroup samples, average intervention costs were similar in the 3 study arms, and at 18 months, there were no statistically significant differences in direct VA medical costs or total VA costs between treatment arms and usual care. CONCLUSIONS: To optimize investment in telephone-based home interventions such as the HINTS, it is important to identify groups of patients who are most likely to benefit from more intensive home BP management.

OBJECTIVES: Outpatient visit co-payments have increased in recent years. We estimate the patient response to a price change for specialty care, based on a co-payment increase from $15 to $50 per visit for veterans with hypertension. DESIGN, SETTING, AND PATIENTS: A retrospective cohort of veterans required to pay co-payments was compared with veterans exempt from co-payments whose nonequivalence was reduced via propensity score matching. Specialty care expenditures in 2000-2003 were estimated via a two-part mixed model to account for the correlation of the use and level outcomes over time, and results from this correlated two-part model were compared with an uncorrelated two-part model and a correlated random intercept two-part mixed model. RESULTS: A $35 specialty visit co-payment increase had no impact on the likelihood of seeking specialty care but induced lower specialty expenditures over time among users who were required to pay co-payments. The log ratio of price responsiveness (semi-elasticity) for specialty care increased from -0.25 to -0.31 after the co-payment increase. Estimates were similar across the three models. CONCLUSION: A significant increase in specialty visit co-payments reduced specialty expenditures among patients obtaining medications at the Veterans Affairs medical centers. Longitudinal expenditure analysis may be improved using recent advances in two-part model methods.
