Patients are receptive to diverse strategies to screen for cost barriers but want participatory decision making to address cost-efficacy tradeoffs.
ABSTRACT
Objectives
Given that many patients with chronic diseases face cost-related barriers to care, we evaluated patients’ views on which providers (both physicians and nonphysicians) to involve and which methods to use to screen for those barriers. We also examined patients’ preferences for how physicians consider cost-efficacy trade-offs in decisions.

Study Design
A national survey of 1400 randomly sampled adults with a chronic disease seeking financial assistance (842 respondents).

Methods
Participants rated their comfort with various providers and tools for identifying cost barriers. Then they rated a randomly assigned clinical vignette that described how a clinical decision was made in the context of a cost-efficacy tradeoff. Vignettes depicted 3 decision types: cost-conscious physician, cost-indifferent physician, or patient-directed. Comfort was rated from 1 to 10—ratings above 7 indicated high comfort.

Results
More respondents reported high comfort with physicians screening for cost barriers (81.1%) than with pharmacists (74.8%; P = .002), nurses (69.4%; P <.001), professional counselors (68.3%; P <.001), and trained volunteers (50.5%; P <.001). Regarding screening for cost barriers using administrative records, more respondents reported higher comfort with doctors’ offices (58.8%) than with insurance companies (53.3%; P = .03), but similar levels of comfort compared to pharmacies (62.1%; P = .17). Participants favored “patient-directed” decisions with physician input (odds ratio, 4.64; 95% CI, 3.14-6.84; P <.001) compared with “cost-conscious” decisions in which physicians unilaterally decided how to manage cost-efficacy tradeoffs.

Conclusions
Patients were open to a range of cost-barrier screening approaches, but most favor direct conversations with their doctor and shared decision making in decisions involving cost-efficacy trade-offs.

Prior studies show that patients frequently encounter cost barriers leading to costrelated nonadherence with medications, but rarely do patients raise these concerns with their doctors nor do their doctors initiate discussions on the subject. Our study finds:
  • Many patients are open to a range of cost-barrier screening approaches outside of face-to-face visits with their doctors, including screening by nonphysician members of the healthcare team and administrative mechanisms such as insurer claims reviews or alerts from pharmacies to physician offices.
  • Even when patients face cost barriers, they generally want a participatory decision-making process to address cost-efficacy trade-offs. Physicians need tools to facilitate these discussions.
Financial stress associated with healthcare imposes a substantial burden on US families, including a high rate of cost-related nonadherence to prescription medications.1-8 For example, 20% of seniors in fair or poor health report cost-related nonadherence despite a high rate of Medicare prescription drug coverage.9 Cost-related nonadherence leads to higher rates of morbidity and mortality, including elevated rates of cardiovascular events.10,11

A number of factors suggest that cost barriers will continue to increase. First, despite a recent slowdown, the rate of growth of healthcare costs continues to exceed that of economic growth.12,13 Second, high-deductible health plans, which were further stimulated by the creation of tax-advantaged health savings accounts through the Medicare Modernization Act a decade ago, are growing rapidly, with 19% of workers with employer-sponsored insurance now enrolled.14 Third, although the Affordable Care Act will significantly expand insurance coverage, the minimum coverage requirements will still permit a high level of cost sharing.15 As cost barriers grow, patients will increasingly need assistance in making healthcare decisions that involve trade-offs between the efficacy and affordability of treatment regimens. (We will refer to these decisions as cost-efficacy trade-offs.)

Prior studies have examined attitudes and behaviors regarding physician-patient cost discussions. Those studies showed that patients wanted to discuss costs with their physician and would invite discussions about affordability.16-18 However, just 35% of patients experiencing cost-related nonadherence reported having had a cost discussion with their doctor.17 Although physicians report that cost discussions are important, they often do not recognize when their own patients are experiencing cost barriers.16,19 Physicians also perceive that they lack the knowledge to discuss treatment costs, and that time pressures of an office visit prohibit meaningful discussions.20 Given the infrequency of cost discussions, several experts have proposed deploying other members of healthcare teams to screen for financial stress and potentially intervene.21 However, we are not aware of any studies that have tested the acceptability among patients of screening or interventions outside of traditional physician-patient face-to-face encounters.

As cost barriers become more prevalent and start to be recognized, it is important to understand how physicians and patients should incorporate financial considerations into medical decisions. The literature on patient preferences for their own role in medical decision making shows heterogeneous preferences.22 In a national survey,22 the majority of patients reported that they wanted to be asked their opinions on therapeutic options and be offered choices, yet almost half preferred to rely exclusively on their physician’s knowledge to acquire information, and just over half preferred to still leave final decisions to their physician. To our knowledge, studies have not examined patients’ preferences regarding physicians’ roles in navigating cost-efficacy trade-offs.

In this study, we had 2 main objectives. First, in a sample of patients with a chronic disease, we evaluated comfort with being screened for medication cost-related barriers by different types of healthcare providers and through different methods. Second, we examined patients’ preferences for physician and patient roles in making medical decisions involving cost-efficacy trade-offs.

METHODS

We conducted a mail survey of a random sample of adults with a chronic disease who had applied for financial support to the HealthWell Foundation, a national nonprofit organization that assists patients with co-payments, co-insurance, and health insurance premiums (www.healthwellfoundation.org); both individual and corporate donors contribute to the HealthWell Foundation. Embedded in the mailed survey was a randomized experiment to evaluate patient preferences regarding physician approaches to helping patients navigate cost-efficacy trade-offs in the prescribing of medications. The University of Pennsylvania Institutional Review Board approved this study, which was funded by the HealthWell Foundation.

Survey Instrument

We asked participants to rate their level of comfort with their own doctor and other members of the healthcare team screening them for medication cost–related barriers to care. In addition to their own doctor, we asked about nurses, professional counselors, and trained volunteers at their doctor’s office, as well as pharmacists where they fill prescriptions. We also asked participants to rate their comfort with a range of strategies outside the normal doctor-patient visit, to screen for cost-related nonadherence or cost-barriers. These strategies included “having someone from your doctor’s office review your records to see how often you fill your prescriptions”; “having your insurance company review your records to see how often you fill your prescriptions”; “having your pharmacy review your records to see how often you fill your prescriptions”; “filling out a form in your doctor’s office”; and “responding to an email message from your doctor’s office.” Participants rated their level of comfort with each item in this section on a 1-to-10 scale where 1 was very uncomfortable and 10, very comfortable.

The next section of the survey included an embedded experiment in which participants were randomized to 1 of 3 versions of a vignette describing a clinical decision with cost-efficacy trade-offs. Every survey included the following: “Lucy has high cholesterol. She can take a medicine to help prevent a heart attack. The options are Medicine A and Medicine B. Medicine A costs Lucy $20 a month. It works fairly well. 80 out of 100 people get better. Medicine B costs Lucy $100 a month. It works very well. 99 out of 100 people get better.” The experimental conditions varied as follows, with one-third of the survey sample allocated at random to each condition; in condition 1, the “cost-conscious” decision style, Dr Thomas is aware that Lucy is having difficulty paying for her medications and makes a unilateral decision to prescribe Medicine A—the less expensive, less effective medication. In condition 2, the “cost-indifferent” decision style, Dr Thomas knows that Lucy is having difficulty paying for her medicine but unilaterally decides to prescribe Medicine B because it is “best.” In condition 3, the “patient-directed” style, Dr Thomas knows Lucy is having trouble paying for her medicines. Before Dr Thomas prescribes a medicine, she discusses Medicines A and B with Lucy and lets Lucy decide. Participants rated their level of comfort with the decision style depicted in the condition to which they were randomized on a 1-to-10 scale, where 1 was very uncomfortable and 10, very comfortable.

We also asked respondents about their experiences with cost-related nonadherence or difficulty paying for their medications in the last year, as well as whether they would like to discuss costs with their doctor. Self-rated health was measured using the SF-1 questionnaire, a predictor of all-cause mortality.23 Physician trust was measured using a 5-item instrument.24 The HealthWell Foundation provided demographic information for participants, including income, age, insurance status, and marital status.

Survey Administration

We administered the survey between August 2012 and October 2012. We mailed surveys to 1400 individuals randomly selected from the HealthWell Foundation database. We sent each individual an introductory letter, followed approximately 5 days later by the mailed survey and consent form as well as a $5 participation incentive. We followed this mailing with a postcard reminder 1 week later, and a fourth and final mailing containing a second survey approximately 2 weeks after that. Among the people invited to participate, 107 were unreachable because of incorrect addresses; and 6 people were deceased according to a family member. A total of 842 participants responded for a final survey response rate of 60.4%.

Statistical Analysis

Our main outcomes were how comfortable the respondent was with the method or decision described in the survey instrument. We dichotomized our outcome into high comfort (8 to 10) versus low to medium comfort (1 to 7). We tested bivariate associations between demographic characteristics, self-reported health status, self-reported cost difficulty, and self-reported cost-related nonadherence with our main outcomes using χ2 statistics. We also tested for differences between our 3 experimental groups using χ2 statistics. We adjusted for characteristics that differed (P <.10) between experimental groups using logistic regression. We performed all analyses using the Stata software program, version 12.1 (StataCorpLP, College Station, Texas).

RESULTS

In this sample of adults with a chronic disease who faced financial challenges associated with their healthcare, the majority were women and almost half were 65 years or older (Table 1). Although 70% of the sample earned less than $30,000 per year, most respondents had some form of health insurance—either through a private insurer or through Medicare. More than half of the respondents rated their health as fair or poor. The majority of participants noted that they had experienced difficulty paying for prescriptions and/or cost-related medication nonadherence in the past year. Most agreed that, “I want my doctor to think about cost when choosing a medicine for me” (86%). Among the 1400 people mailed a survey, responders were somewhat older than nonresponders (P = .05), but had similar income (P = .36) and insurance  coverage (P = .20) (eAppendix A).

Financial Screening by Healthcare Team Members

Participants were asked how comfortable they would be with different members of the healthcare team inquiring about their own financial challenges (Table 2). Responses suggest that patients view members of the healthcare team differently. Participants most often reported being highly comfortable being questioned by physicians (81.1%), followed closely by pharmacists (74.8%). Nurses (69.4%) and professional counselors (68.3%) ranked next in terms of participants’ comfort, with trained volunteers (50.5%) least often endorsed. These ratings were similar across all sociodemographic groups. Participants who reported a high degree of physician trust reported higher levels of comfort with all members of the healthcare team.
