A conceptually based approach to understanding chronically ill patients' responses to medication cost pressures.

Prescription medications enhance the well-being of most chronically ill patients. Many individuals, however, struggle with how to pay for their treatments and as a result experience problems with self-care and health maintenance. Although studies have documented that high out-of-pocket costs are associated with medication non-adherence, little research on prescription cost sharing has been theoretically grounded in knowledge of the more general determinants of patients' self-management behaviors and chronic disease outcomes. We present a conceptual framework for understanding the influence of patient, medication, clinician, and health system factors on individuals' responses to medication costs. We review what is known about how these factors influence medication adherence, identify possible strategies through which clinicians, health systems, and policy-makers may assist patients burdened by their medication costs, and highlight areas in need of further research. Although medication costs represent a burden to chronically ill patients worldwide, most patients report using their medication as prescribed despite the costs, and others report cost-related underuse despite an apparent ability to afford those treatments. The cost-adherence relationship is modified by contextual factors, including patients' characteristics (e.g., age, ethnicity, and attitudes toward medications), the type of medications they are using (e.g., the complexity of dosing and the drug's clinical target), clinician factors (e.g., choice of first-line agent and communication about medication costs), and health system factors (e.g., efforts to influence clinicians' prescribing and to help patients apply for financial assistance programs). Understanding these relationships will enable clinicians and policy-makers to better design pharmacy benefits and assist patients in taking their medication as prescribed. The next generation of studies examining the consequences of prescription drug costs should expand our knowledge of the ways in which these co-factors influence patients' responses to medication cost pressures.

Patient strategies to cope with high prescription medication costs: who is cutting back on necessities, increasing debt, or underusing medications?

Many chronically ill adults in the United States face high prescription medication costs, yet little is known about the strategies patients adopt to cope with these costs. Through a national survey of 4,055 adults taking prescription medications for one of five chronic diseases, we compared whether respondents cut back on necessities such as food or heat to pay for medications, increased debt, or underused medications because of cost. We also examined the sociodemographic and clinical correlates and differential use by different sub-groups of these three strategies. Overall, 31% of respondents reported pursuing at least one of the strategies over the prior 12 months. Twenty-two percent had cut back on necessities, 16% had increased their debt burden, and 18% had underused prescription drugs. Among patients who underused their medication, 67% also had cut necessities or increased debt. Although we found significant differences in the way patients with varying socio-demographic characteristics responded to medication cost pressures, use of all these strategies was especially common among patients who were low-income, in poor health, and taking multiple medications.

Perceived health status and perceived diabetes control: psychological indicators and accuracy.

OBJECTIVE: The aim of this study is to assess the association of psychological, as well as physical and sociodemographic, indicators with patients' ratings of personal health status and diabetes control and to investigate the association of mental health and depression with errors in the perception of diabetes control. METHOD: A sociodemographically diverse sample of 623 diabetes patients was recruited from the general medicine clinics of a county health care system and a Veterans Affairs health care system. We examined three types of determinants of patients' health perceptions: physical health indicators (symptoms, comorbid diagnoses, and glycosylated hemoglobin or HbA1c levels), psychological health indicators (general mental health and diabetes-related worry), and sociodemographic factors (age, race, gender, income, and education). RESULTS: After controlling for patient' sociodemographic characteristics, perceived general health was associated with patients' symptom burden and emotional distress (but not with patients' HbA1c levels). Perceived diabetes control additionally was associated with HbA1c and diabetes-related worries. Further analyses showed that both mental health and diagnosed depression were associated with errors in personal appraisals of diabetes control, with depressed patients more often inaccurately assessing their glycemic control as poor (false-positive error) and nondepressed patients more often missing poor HbA1c levels (false-negative error). CONCLUSIONS: Findings indicate that patients use a comprehensive model for assessing their general health and that depression may lead to more accurate assessments of poor glucose control.

Is education associated with mortality for breast cancer and cardiovascular disease among black and white women?

BACKGROUND: Although low socioeconomic status (SES) has been found to be an important risk factor for all-cause mortality in women, the association is inconsistent across specific causes of death. SES appears to have different associations with 2 common causes of mortality in women: low SES is associated with greater cardiovascular disease (CVD) mortality in women but may also be associated with lower breast cancer mortality. OBJECTIVE: We examined the association between SES and CVD and breast cancer mortality among black and white women. METHODS: Our analysis sample included black and white women participating in the National Longitudinal Mortality Study, which links US Census Bureau Current Population Surveys with the National Death Index between 1979 and 1989. Education and income were used as SES indicators. For each cause of death, we used multivariate logistic regression to estimate variation in mortality risk across SES levels within each racial group. RESULTS: The sample included 21,303 black women and 186,322 white women. Unadjusted cumulative incidence (over a mean follow-up period of 8.7 years) of CVD mortality was 4.2% among black women and 2.3% among white women, and of breast cancer mortality was 0.3% among black women and 0.4% among white women. After adjustment for age, marital status, and urban or rural residence, less education was still associated with greater CVD mortality among black women (odds ratio [OR], 1.8; 95% Cl, 1.03-3.0) and white women (OR, 1.4; 95% Cl, 1.3-1.6). However, less than a high school education was associated with lower breast cancer mortality among white women (OR, 0.73; 95% CI, 0.6-0.9) but not among black women (OR, 1.1; 95% Cl, 0.5-2.3). Similar ORs were obtained when income was examined. CONCLUSIONS: The association between SES and cause-specific mortality may differ between black and white women for breast cancer death but not CVD death. Better understanding of these inter actions could guide the targeting of more effective interventions.

Integrating physical activity into mental health services for persons with serious mental illness.

This article reviews evidence supporting the need for interventions to promote physical activity among persons with serious mental illness. Principles of designing effective physical activity interventions are discussed along with ways to adapt such interventions for this population. Individuals with serious mental illness are at high risk of chronic diseases associated with sedentary behavior, including diabetes and cardiovascular disease. The effects of lifestyle modification on chronic disease outcomes are large and consistent across multiple studies. Evidence for the psychological benefits for clinical populations comes from two meta-analyses of outcomes of depressed patients that showed that effects of exercise were similar to those of psychotherapeutic interventions. Exercise can also alleviate secondary symptoms such as low self-esteem and social withdrawal. Although structured group programs can be effective for persons with serious mental illness, especially walking programs, lifestyle changes that focus on accumulation of moderate-intensity activity throughout the day may be most appropriate. Research suggests that exercise is well accepted by people with serious mental illness and is often considered one of the most valued components of treatment. Adherence to physical activity interventions appears comparable to that in the general population. Mental health service providers can provide effective, evidence-based physical activity interventions for individuals with serious mental illness.

The effect of chronic pain on diabetes patients' self-management.

OBJECTIVE: Many adults experience chronic pain, yet little is known about the consequences of such pain among individuals with diabetes. The purpose of this study was to examine whether and how chronic pain affects diabetes self-management. RESEARCH DESIGN AND METHODS: This is a cross-sectional study of 993 patients with diabetes receiving care through the Department of Veterans Affairs (VA). Data on chronic pain, defined as pain present most of the time for 6 months or more during the past year, and diabetes self-management were collected through a written survey. Multivariable regression techniques were used to examine the association between the presence and severity of chronic pain and difficulty with diabetes self-management, adjusting for sociodemographic and other health characteristics including depression. RESULTS: Approximately 60% of respondents reported chronic pain. Patients with chronic pain had poorer diabetes self-management overall (P = 0.002) and more difficulty following a recommended exercise plan (adjusted odds ratio [OR] 3.0 [95% CI 2.1-4.1]) and eating plan (1.6 [1.2-2.1]). Individuals with severe or very severe pain, compared with mild or moderate, reported significantly poorer diabetes self-management (P = 0.003), including greater difficulty with taking diabetes medications (2.0 [1.2-3.4]) and exercise (2.5 [1.3-5.0]). CONCLUSIONS: Chronic pain was prevalent in this cohort of patients with diabetes. Even after controlling for general health status and depressive symptoms, chronic pain was a major limiting factor in the performance of self-care behaviors that are important for minimizing diabetes-related complications. Competing demands, such as chronic pain, should be considered when working with patients to develop effective diabetes self-care regimens.

The relationship between knowledge of recent HbA1c values and diabetes care understanding and self-management.

OBJECTIVE: Knowledge of one's actual and target health outcomes (such as HbA(1c) values) is hypothesized to be a prerequisite for effective patient involvement in managing chronic diseases such as diabetes. We examined 1) the frequency and correlates of knowing one's most recent HbA(1c) test result and 2) whether knowing one's HbA(1c) value is associated with a more accurate assessment of diabetes control and better diabetes self-care understanding, self-efficacy, and behaviors related to glycemic control. RESEARCH DESIGN AND METHODS: We conducted a cross-sectional survey of a sample of 686 U.S. adults with type 2 diabetes in five health systems who had HbA(1c) checked in the previous 6 months. Independent variables included patient characteristics, health care provider communication, and health system type. We examined bivariate and multivariate associations between each variable and the respondents' knowledge of their last HbA(1c) values and assessed whether knowledge of HbA(1c) was associated with key diabetes care attitudes and behaviors. RESULTS: Of the respondents, 66% reported that they did not know their last HbA(1c) value and only 25% accurately reported that value. In multivariate analyses, more years of formal education and high evaluations of provider thoroughness of communication were independently associated with HbA(1c) knowledge. Respondents who knew their last HbA(1c) value had higher odds of accurately assessing their diabetes control (adjusted odds ratio 1.59, 95% CI 1.05-2.42) and better reported understanding of their diabetes care (P < 0.001). HbA(1c) knowledge was not associated with respondents' diabetes care self-efficacy or reported self-management behaviors. CONCLUSIONS: Respondents who knew their HbA(1c) values reported better diabetes care understanding and assessment of their glycemic control than those who did not. Knowledge of one's HbA(1c) level alone, however, was not sufficient to translate increased understanding of diabetes care into the increased confidence and motivation necessary to improve patients' diabetes self-management. Strategies to provide information to patients must be combined with other behavioral strategies to motivate and help patients effectively manage their diabetes.

Cost-related medication underuse: do patients with chronic illnesses tell their doctors?

BACKGROUND: Although many chronically ill patients underuse prescription medications because of cost concerns, we know little about their discussions with clinicians about this issue. METHODS: Nationwide survey of 660 older adults with chronic illnesses who reported underusing medication in the prior year because of cost. We assessed whether patients discussed cost-related medication underuse with clinicians, reasons that some patients did not talk with clinicians about this problem, how clinicians responded when this issue was raised, and how helpful patients perceived clinicians to be. RESULTS: Two thirds of respondents never told a clinician in advance that they planned to underuse medication because of the cost, and 35% never discussed the issue at all. Of those who did not tell a clinician, 66% reported that nobody asked them about their ability to pay for prescriptions and 58% reported that they did not think providers could help them. When patients talked with clinicians about medication costs, 72% found those conversations helpful. However, 31% reported that their medications were never changed to a generic or less expensive alternative, and few patients were given other forms of assistance such as information about programs that help pay drug costs (30%) or where to purchase less expensive medication (28%). Patients were most likely to find clinicians helpful if clinicians provided free samples, asked about problems paying for prescriptions, and offered advice about how to pay for patients' current regimens. CONCLUSIONS: About one third of chronically ill adults who underuse prescription medication because of the cost never talk with clinicians in advance, and many never raise this issue at all. Clinicians should take a more proactive role in identifying and assisting patients who have problems paying for prescription drugs.

Diabetes care quality in the Veterans Affairs Health Care System and commercial managed care: the TRIAD study.

BACKGROUND: No studies have compared care in the Department of Veterans Affairs (VA) with that delivered in commercial managed care organizations, nor have studies focused in depth on care comparisons for chronic, outpatient conditions. OBJECTIVE: To compare the quality of diabetes care between patients in the VA system and those enrolled in commercial managed care organizations by using equivalent sampling and measurement methods. DESIGN: Cross-sectional patient survey with retrospective review of medical records. SETTING: 5 VA medical centers and 8 commercial managed care organizations in 5 matched geographic regions. PARTICIPANTS: 8205 diabetic patients: 1285 in the VA system and 6920 in commercial managed care. MEASUREMENTS: We compared scores on identically specified quality measures for 7 diabetes care processes and 3 diabetes intermediate outcomes and on 4 dimensions of satisfaction. Scores were expressed as the percentage of patients receiving indicated care and were adjusted for patients' demographic and health characteristics. RESULTS: Patients in the VA system had better scores than patients in commercial managed care on all process measures (for example, 93% vs. 83% for annual hemoglobin A1c; P = 0.006; 91% vs. 75% for annual eye examination; P < 0.001). Blood pressure control was poor in both groups (52% to 53% of persons had blood pressure < 140/90 mm Hg), but patients in the VA system had better control of low-density lipoprotein cholesterol and hemoglobin A1c (for example, 86% vs. 72% for low-density lipoprotein cholesterol level < 3.37 mmol/L [<130 mg/dL]; P = 0.002). Satisfaction was similar in the 2 groups. LIMITATIONS: Our results may not be generalizable to all regions or health plans, and some of the differences in performance could reflect differences in documentation. CONCLUSIONS: Diabetes processes of care and 2 of 3 intermediate outcomes were better for patients in the VA system than for patients in commercial managed care. However, both VA and commercial managed care had room for improvement, especially for blood pressure control.

Clinician identification of chronically ill patients who have problems paying for prescription medications.

PURPOSE: Little is known about whether health care providers are effectively identifying patients who have difficulty covering the costs of out-of-pocket prescription medications. We examined whether and how providers are identifying chronically ill adults who have potential problems paying for prescription medications. METHODS: We conducted a cross-sectional survey of a national sample of 4050 adults aged 50 years or older who use prescription medications for at least one of five chronic health conditions. The primary outcome measure was patient report of being asked by a doctor or nurse in the prior 12 months whether the patient could afford the prescribed medication. The measures of prescription cost burden were cost-related underuse of medications, cutting back on other necessities to pay for medications, and worries about medication costs. We adjusted for patient income, education, race/ethnicity, age, sex, health status, number of prescribed medications, pharmacy benefits, frequency of outpatient visits, having a regular health care provider, and sampling weights. RESULTS: In the weighted analyses, 16% (547/4050) of respondents reported that they had been asked about potential problems paying for a prescribed medication. Only 360 (24%) of the 1499 respondents who reported one or more burdens from out-of-pocket medication costs reported being asked this question. After adjusting for potential confounders, patients who had cut back on medication use or other necessities to cover payments were no more likely than other patients to be asked about the ability to pay for prescription medications. Concerns about medication costs, being a racial/ethnic minority, taking seven or more prescription medications, and having no prescription coverage were independently associated with a greater likelihood of being asked about possible problems with prescription costs. CONCLUSION: Few chronically ill patients who are at risk of or experiencing problems related to prescription medication costs report that their clinicians had asked them about possible medication payment difficulties.

Interactive behavior change technology. A partial solution to the competing demands of primary care.

BACKGROUND: Primary care practices are faced with the challenge of having too much to do in too little time. As a result, behavioral counseling is often overlooked, especially for patients with multiple health behaviors in need of change. METHODS: This paper describes recent examples of the application of interactive behavior change technologies (IBCTs) to deliver health behavior change counseling before, during, and after the office visit to inform and enhance patient-clinician interactions around these issues. The 5A's framework (assess, advise, agree, assist, arrange follow-up) is used to consider how interactive technology can be used to implement behavior change counseling more consistently. RESULTS: A variety of IBCTs, including the Internet, clinic-based CD-ROMs, and interactive voice-response telephone calls have been shown to be feasible and potentially valuable adjuncts to clinic-based behavioral counseling. These technologies can both increase the effectiveness of behavioral counseling and extend the reach of these services to patients with barriers to face-to-face interactions. CONCLUSIONS: If appropriately developed with the context of primary care in mind and integrated as part of a systems approach to intervention, IBCT can be a feasible and appropriate aid for primary care. Recommendations are made for the types of IBCT aids and research that are needed to realize this potential.

Health insurance status, cost-related medication underuse, and outcomes among diabetes patients in three systems of care.

BACKGROUND: Chronically ill patients often experience difficulty paying for their medications and, as a result, use less than prescribed. OBJECTIVES: The objectives of this study were to determine the relationship between patients with diabetes' health insurance coverage and cost-related medication underuse, the association between cost-related underuse and health outcomes, and the role of comorbidity in this process. RESEARCH DESIGN: We used a patient survey with linkage to insurance information and hemoglobin A1C (A1C) test results. PATIENTS: We studied 766 adults with diabetes recruited from 3 Veterans Affairs (VA), 1 county, and 1 university healthcare system. MAIN OUTCOMES: Main outcomes consisted of self-reported medication underuse as a result of cost, A1C levels, symptom burden, and Medical Outcomes Study 12-Item Short-Form physical and mental functioning scores. RESULTS: Fewer VA patients reported cost-related medication underuse (9%) than patients with private insurance (18%), Medicare (25%), Medicaid (31%), or no health insurance (40%; P <0.0001). Underuse was substantially more common among patients with multiple comorbid chronic illnesses, except those who used VA care. The risk of cost-related underuse for patients with 3+ comorbidities was 2.8 times as high among privately insured patients as VA patients (95% confidence interval, 1.2-6.5), and 4.3 to 8.3 times as high among patients with Medicare, Medicaid, or no insurance. Individuals reporting cost-related medication underuse had A1C levels that were substantially higher than other patients (P <0.0001), more symptoms, and poorer physical and mental functioning (all P <0.05). CONCLUSIONS: Many patients with diabetes use less of their medication than prescribed because of the cost, and those reporting cost-related adherence problems have poorer health. Cost-related adherence problems are especially common among patients with diabetes with comorbid diseases, although the VA's drug coverage may protect patients from this increased risk.

The health effects of restricting prescription medication use because of cost.

BACKGROUND: High out-of-pocket expenditures for prescription medications could lead people with chronic illnesses to restrict their use of these medications. Whether adults experience adverse health outcomes after having restricted medication use because of cost is not known. METHODS: We analyzed data from 2 prospective cohort studies of adults who reported regularly taking prescription medications using 2 waves of the Health and Retirement Study (HRS), a national survey of adults aged 51 to 61 in 1992, and the Asset and Health Dynamics Among the Oldest Old (AHEAD) Study, a national survey of adults aged 70 or older in 1993 (n = 7991). We used multivariable logistic and Poisson regression models to assess the independent effect on health outcomes over 2 to 3 years of follow up of reporting in 1995-1996 having taken less medicine than prescribed because of cost during the prior 2 years. After adjusting for differences in sociodemographic characteristics, health status, smoking, alcohol consumption, body mass index (BMI), and comorbid chronic conditions, we determined the risk of a significant decline in overall health among respondents in good to excellent health at baseline and of developing new disease-related adverse outcomes among respondents with cardiovascular disease, diabetes, arthritis, and depression. RESULTS: In adjusted analyses, 32.1% of those who had restricted medications because of cost reported a significant decline in their health status compared with 21.2% of those who had not (adjusted odds ratio [AOR], 1.76; confidence interval [CI], 1.27-2.44). Respondents with cardiovascular disease who restricted medications reported higher rates of angina (11.9% vs. 8.2%; AOR, 1.50; CI, 1.09-2.07) and experienced higher rates of nonfatal heart attacks or strokes (7.8% vs. 5.3%; AOR, 1.51; CI, 1.02-2.25). After adjusting for potential confounders, we found no differences in disease-specific complications among respondents with arthritis and diabetes, and increased rates of depression only among the older cohort. CONCLUSIONS: Cost-related medication restriction among middle-aged and elderly Americans is associated with an increased risk of a subsequent decline in their self-reported health status, and among those with preexisting cardiovascular disease with higher rates of angina and nonfatal heart attacks or strokes. Such cost-related medication restriction could be a mechanism for worse health outcomes among low-income and other vulnerable populations who lack adequate insurance coverage.

Cost-related medication underuse among chronically ill adults: the treatments people forgo, how often, and who is at risk.

OBJECTIVES: We sought information about the cost-related underuse of medications-which medications are underused, by whom, and how often. METHODS: Chronically ill adults were asked to identify how often they underused prescription medication for 16 health conditions because of the cost. RESULTS: Eighteen percent of respondents cut back on medication use owing to cost in the previous year, and 14% used less medication at least monthly. Although rates of underuse varied substantially across treatments, prescription coverage and out-of-pocket costs were determinants of underuse across medication types. CONCLUSIONS: Many chronically ill adults frequently cut back on medications owing to cost. Patients are selective about the treatments they forgo. Out-of-pocket costs and inadequate prescription coverage may lead to adherence problems for many important medication types.

Problems paying out-of-pocket medication costs among older adults with diabetes.

OBJECTIVE: To identify problems faced by older adults with diabetes due to out-of-pocket medication costs. RESEARCH DESIGN AND METHODS: In this cross-sectional national survey of 875 adults with diabetes treated with hypoglycemic medication, respondents reported whether they had underused prescription medications due to cost pressures or had experienced other financial problems associated with medication costs such as forgoing basic necessities. Respondents also described their interactions with clinicians about medication costs. RESULTS: A total of 19% of respondents reported cutting back on medication use in the prior year due to cost, 11% reported cutting back on their diabetes medications, and 7% reported cutting back on their diabetes medications at least once per month. Moreover, 28% reported forgoing food or other essentials to pay medication costs, 14% increased their credit card debt, and 10% borrowed money from family or friends to pay for their prescriptions. Medication cost problems were especially common among respondents who were younger, had higher monthly out-of-pocket costs, and had no prescription drug coverage. In general, few respondents, including those reporting medication cost problems, reported that their health care providers had given them information or other assistance to address medication cost pressures. CONCLUSIONS: Out-of-pocket medication costs pose a significant burden to many adults with diabetes and contribute to decreased treatment adherence. Clinicians should actively identify patients with diabetes who are facing medication cost pressures and assist them by modifying their medication regimens, helping them understand the importance of each prescribed medication, providing information on sources of low-cost drugs, and linking patients with coverage programs.
