Health literacy weakly but consistently predicts primary care patient dissatisfaction.

OBJECTIVES: To study relationships between health literacy and multiple satisfaction domains. Health literacy is related to some domains of patient satisfaction such as communication and understanding, but little is known about relationships of health literacy with other satisfaction domains. Moreover, the importance of health literacy in predicting satisfaction compared with other patient sociodemographics is underexplored. DESIGN: Cross-sectional survey. SETTING: Primary care waiting areas with a Veterans Administration Medical Center and a university health system. PARTICIPANTS: One thousand five hundred and twenty-eight primary care patients. MAIN OUTCOME MEASURES: A brief demographics questionnaire, the Rapid Estimate of Adult Literacy in Medicine, the Veterans Affairs ambulatory care patient satisfaction survey, and an adaptation of the Charlson Comorbidity Index. RESULTS: In unadjusted regression analyses, lower health literacy level was a significant predictor of worse satisfaction in 7 of 10 domains (P < 0.01). When adjusting for patient sociodemographics, predicted relationships remained significant in six of the seven domains (P < 0.05), with each unit change in the 4-stage literacy classification associated with a 3-6 point decrease in dissatisfaction scores (0-100 scale). Health literacy did not predict overall dissatisfaction (P = 0.55). CONCLUSIONS: These results suggest that health literacy, as assessed through a pronunciation exercise that is closely related to more comprehensive measures of literacy, has a consistent, albeit weak relationship with patient satisfaction. Future work is needed to clarify if patients with lower literacy are really receiving different care than those with higher literacy and to pinpoint the sources of their more negative responses.

Patient preferences can be misleading as explanations for racial disparities in health care.

Addressing racial differences in US health care is difficult, in part because the origins of these differences are complex and poorly understood and also because only some differences may represent legitimate agendas for reform. For example, racial differences that result from differences in access or from clinician prejudices are symptoms of a problem that must be addressed; in contrast, racial differences that arise from different preferences for health care might be seen as acceptable consequences of variation in personal or cultural values that are worth respecting and preserving. However, we believe that this distinction is sometimes overstated. We present several fictitious clinical stories to illustrate how what appear to be individual or cultural preferences are often substantially shaped by modifiable practices of the health care system. True differences in preference that are worthy of respect surely exist between individuals or demographic groups, but some apparent differences in preference may actually reflect problems with the health care system that are worthy of remediation. Uncovering the hidden constraints that we impose on health care choice may help us reduce unwanted disparities in health care.

Insurance coverage for obesity treatment.

Recent work demonstrates the benefits of weight loss from intensive lifestyle modification. One barrier to counseling may be lack of reimbursement. We sought to quantify the obesity coverage policies of insurers in Pennsylvania. A three-page questionnaire was sent to eligible Pennsylvania health plans. Respondents included company medical directors and administrators from other departments, including public relations, provider relations, disease management, and utilization review. The questionnaire inquired about major treatment modalities for obesity, including details of coverage. Sixteen of 19 eligible plans (84%) responded. All plans provided some coverage for bariatric surgery. Nine out of 16 companies (56%) stated that they covered individual dietary counseling, but only five paid for intensive counseling. Less than 50% of plans reimbursed other forms of lifestyle modification or weight loss medication. Surgery was covered significantly more often than all other treatment modalities (P<0.02 for all comparisons). No differences in reimbursement were found by plan type or by number of enrollees. Insurance reimbursement for obesity in Pennsylvania does not consistently reflect recent evidence for the benefits of lifestyle modification. Given the increasing evidence for the clinical and cost-effectiveness of nonsurgical weight loss therapy, coverage policies may begin to change.

Inadequate hepatitis B vaccination and post-exposure evaluation among transplant surgeons: prevalence, correlates, and implications.

OBJECTIVES: To identify the proportion of U.S. transplant surgeons who are adequately vaccinated against hepatitis B virus (HBV), identify characteristics associated with inadequate vaccination, and assess the proportion who had been evaluated for immunization following potential HBV exposures. SUMMARY BACKGROUND DATA: It is unknown what proportion of transplant surgeons are appropriately vaccinated against HBV or evaluated for immunization following operative exposures. METHODS: We mailed questionnaires and to all active U.S. transplant surgeons. We compared demographic characteristics of responders and nonresponders to evaluate the potential for nonresponse bias. RESULTS: Of 619 eligible respondents, 347 (56.1%) returned completed questionnaires. Of the 311 surgeons for whom HBV vaccination was indicated (all surgeons with neither a prior history of HBV infection nor a prior adverse reaction to the vaccine itself), 70 (22.5%; 95% confidence interval [CI], 18.0-27.6%) received fewer than the recommended 3 injections. Surgeon characteristics associated with inadequate vaccination included length of clinical practice (odds ratio [OR], 1.5 per 10-year increment in duration of practice; 95% CI, 1.1-2.2), increased fear of infection (OR, 1.2 for each unit increase in fear out of 10; 95% CI, 1.1-1.4), and lack of recent testing for HBV infection (OR, 2.0; 95% CI, 1.1-3.8). Of the 94 surgeons (27.3%) reporting at least one needle-stick exposure while operating on an HBV-infected patient, 14 (14.9%) were inadequately vaccinated; of these 14, only 5 (35.7%) sought appropriate serologic testing and counseling for active immunization. Surgeons underestimated both the risks of percutaneous exposure while operating, and of becoming infected with HBV if exposed. CONCLUSIONS: Many transplant surgeons are inadequately vaccinated against HBV and fail to seek evaluation following possible exposures. Underestimation of the risks of HBV exposure and transmission may relate to these failures. Requiring documentation of HBV vaccination and immunity to maintain operating room privileges may protect surgeons, their patients, and operating room staff.

Racial differences in attitudes toward innovative medical technology.

BACKGROUND: New medical technologies are used at different rates among whites and blacks. This variation may be partially explained by racial differences in patient innovativeness-the propensity of patients to adopt unfamiliar therapies. OBJECTIVE: To measure how innovativeness varies among patients and how it may influence patients' attitudes toward new medical technologies. DESIGN: Cross-sectional survey. PARTICIPANTS: Primary care patients (n=171-108 blacks, 63 whites) at an urban Veterans Affairs medical center. MEASUREMENTS: Respondents answered questions about their general innovativeness and innovativeness regarding medical technology, and they responded to a vignette describing either a hypothetical new prescription drug or implantable device. RESULTS: There were no significant racial differences in general innovativeness, but whites had higher medical technology innovativeness (P=.001). Whites were also more likely to accept the new prescription drug (P=.003), but did not differ from blacks in acceptance of the new implantable device. In multivariate analyses, lower medical technology innovativeness scores among blacks were significantly associated with less favorable reactions to both the prescription drug (P<.001) and the medical device (P<.001). In contrast, although whites with lower medical technology innovativeness were similarly less inclined to accept the new implantable device (P=.02), there was no significant association between medical technology innovativeness and positive attitudes to the new prescription drug among whites. CONCLUSIONS: Blacks and whites have differing attitudes toward medical innovation. These differences are associated with significant racial differences in response to particular health care technologies. These findings suggest potentially remediable causes for racial differences in the utilization of innovative medical technologies.

A randomized controlled trial of financial incentives for smoking cessation.

BACKGROUND: Although 435,000 Americans die each year of tobacco-related illness, only approximately 3% of smokers quit each year. Financial incentives have been shown to be effective in modifying behavior within highly structured settings, such as drug treatment programs, but this has not been shown in treating chronic disease in less structured settings. The objective of this study was to determine whether modest financial incentives increase the rate of smoking cessation program enrollment, completion, and quit rates in a outpatient clinical setting. METHODS: 179 smokers at the Philadelphia Veterans Affairs Medical Center who reported smoking at least 10 cigarettes per day were randomized into incentive and non-incentive groups. Both groups were offered a free five-class smoking cessation program at the Philadelphia Veterans Affairs Medical Center. The incentive group was also offered $20 for each class attended and $100 if they quit smoking 30 days post program completion. Self-reported smoking cessation was confirmed with urine cotinine tests. RESULTS: The incentive group had higher rates of program enrollment (43.3% versus 20.2%; P<0.001) and completion (25.8% versus 12.2%; P=0.02). Quit rates at 75 days were 16.3% in the incentive group versus 4.6% in the control group (P=0.01). At 6 months, quit rates in the incentive group were not significantly higher (6.5%) than in the control group (4.6%; P>0.20). CONCLUSION: Modest financial incentives are associated with significantly higher rates of smoking cessation program enrollment and completion and short-term quit rates. Future studies should consider including an incentive for longer-term cessation.

Epidemiology and prognosis of coma in daytime television dramas.

OBJECTIVE: To determine how soap operas portray, and possibly misrepresent, the likelihood of recovery for patients in coma. DESIGN: Retrospective cohort study. SETTING: Nine soap operas in the United States reviewed between 1 January 1995 and 15 May 2005. SUBJECTS: 64 characters who experienced a period of unconsciousness lasting at least 24 hours. Their final status at the end of the follow-up period was compared with pooled data from a meta-analysis. RESULTS: Comas lasted a median of 13 days (interquartile range 7-25 days). Fifty seven (89%) patients recovered fully, five (8%) died, and two (3%) remained in a vegetative state. Mortality for non-traumatic and traumatic coma was significantly lower than would be predicted from the meta-analysis data (non-traumatic 4% v 53%; traumatic 6% v 67%; Fisher's exact test both P < 0.001). On the day that patients regained consciousness, most (49/57; 86%) had no evidence of limited function, cognitive deficit, or residual disability needing rehabilitation. Compared with meta-analysis data, patients in this sample had a much better than expected chance of returning to normal function (non-traumatic 91% v 1%; traumatic 89% v 7%; both P < 0.001). CONCLUSIONS: The portrayal of coma in soap operas is overly optimistic. Although these programmes are presented as fiction, they may contribute to unrealistic expectations of recovery.

Living Longer and Paying the Price?

Over the past century, there have been tremendous increases in longevity in the United States and most other developed countries. If these trends continue, the costs of paying for public programs like Social Security, Medicare, and Medicaid will escalate at a startling rate with the aging of the "baby boomer" generation. A meeting titled "Living Longer and Paying the Price?" was organized to consider whether current trends in longevity will continue at the current pace, accelerate, or decelerate as a result of public health problems such as obesity and infectious diseases. Further, speakers presented their views on covering the costs of public and private programs for future generations of older adults.

Improving the use of hospice services in nursing homes: a randomized controlled trial.

CONTEXT: Hospice care may improve the quality of end-of-life care for nursing home residents, but hospice is underutilized by this population, at least in part because physicians are not aware of their patients' preferences. OBJECTIVE: To determine whether it is possible to increase hospice utilization and improve the quality of end-of-life care by identifying residents whose goals and preferences are consistent with hospice care. DESIGN, SETTING, AND PARTICIPANTS: Randomized controlled trial (December 2003-December 2004) of nursing home residents and their surrogate decision makers (N=205) in 3 US nursing homes. INTERVENTION: A structured interview identified residents whose goals for care, treatment preferences, and palliative care needs made them appropriate for hospice care. These residents' physicians were notified and asked to authorize a hospice informational visit. MAIN OUTCOME MEASURES: The primary outcome measures were (1) hospice enrollment within 30 days of the intervention and (2) families' ratings of the quality of care for residents who died during the 6-month follow-up period. RESULTS: Of the 205 residents in the study sample, 107 were randomly assigned to receive the intervention, and 98 received usual care. Intervention residents were more likely than usual care residents to enroll in hospice within 30 days (21/107 [20%] vs 1/98 [1%]; P<.001 [Fisher exact test]) and to enroll in hospice during the follow-up period (27/207 [25%] vs 6/98 [6%]; P<.001). Intervention residents had fewer acute care admissions (mean: 0.28 vs 0.49; P = .04 [Wilcoxon rank sum test]) and spent fewer days in an acute care setting (mean: 1.2 vs 3.0; P = .03 [Wilcoxon rank sum test]). Families of intervention residents rated the resident's care more highly than did families of usual care residents (mean on a scale of 1-5: 4.1 vs 2.5; P = .04 [Wilcoxon rank sum test]). CONCLUSION: A simple communication intervention can increase rates of hospice referrals and families' ratings of end-of-life care and may also decrease utilization of acute care resources.

Racial profiling: the unintended consequences of coronary artery bypass graft report cards.

BACKGROUND: Although public release of quality information through report cards is intended to improve health care, there may be unintended consequences of report cards, such as physicians avoiding high-risk patients to improve their ratings. If physicians believe that racial and ethnic minorities are at higher risk for poor outcomes, report cards could worsen existing racial and ethnic disparities in health care. METHODS AND RESULTS: To investigate the impact of New York's CABG report card on racial and ethnic disparities in cardiac care, we estimated differences in the use of CABG, PTCA, and cardiac catheterization between white versus black and Hispanic patients hospitalized for acute myocardial infarction in New York before and after New York's first CABG report card was released, adjusting for patient and hospital characteristics and national changes in racial and ethnic disparities in cardiac care. The racial and ethnic disparity in CABG use significantly increased in New York immediately after New York's CABG report card was released, whereas disparities did not change significantly in the comparison states. There was no differential change in racial and ethnic disparities between New York and the comparison states in the use of cardiac catheterization or PTCA after the CABG report card was released. Over time, this increase in racial and ethnic disparities decreased to levels similar to those before the release of report cards. CONCLUSIONS: The release of CABG report cards in New York was associated with a widening of the disparity in CABG use between white versus black and Hispanic patients.

The unintended consequences of publicly reporting quality information.

Health care report cards publicly report information about physician, hospital, and health plan quality in an attempt to improve that quality. Reporting quality information publicly is presumed to motivate quality improvement through 2 main mechanisms. First, public quality information allows patients, referring physicians, and health care purchasers to preferentially select high-quality physicians. Second, public report cards may motivate physicians to compete on quality and, by providing feedback and by identifying areas for quality improvement initiatives, help physicians to do so. Despite these plausible mechanisms of quality improvement, the value of publicly reporting quality information is largely undemonstrated and public reporting may have unintended and negative consequences on health care. These unintended consequences include causing physicians to avoid sick patients in an attempt to improve their quality ranking, encouraging physicians to achieve "target rates" for health care interventions even when it may be inappropriate among some patients, and discounting patient preferences and clinical judgment. Public reporting of quality information promotes a spirit of openness that may be valuable for enhancing trust of the health professions, but its ability to improve health remains undemonstrated, and public reporting may inadvertently reduce, rather than improve, quality. Given these limitations, it may be necessary to reassess the role of public quality reporting in quality improvement.

In a mailed physician survey, questionnaire length had a threshold effect on response rate.

OBJECTIVE: To examine the association between questionnaire length and response rate in a mailed survey of generalist physicians randomly selected from the American Medical Association master file. STUDY DESIGN AND SETTING: In a pilot study, otherwise similar questionnaires of 30 different lengths (849 to 1,867 words) were mailed to 192 physicians in April 1999. In the main study, questionnaires of 16 different lengths (564 to 988 words) were mailed to 1,700 physicians between June 1999 and January 2000. RESULTS: In the pilot study, response rate decreased from 60% for questionnaires 849 words in length to 16.7% for questionnaires over 1,800 words in length. Logistic regression revealed an odds ratio of 0.887 (95%CI 0.813, 0.968; p=0.006) for word count, expressed in units of 100 words. In the main study, response rate varied between 51.5% and 71.4%. Logistic regression showed no association between response and word count (OR 0.988; 95%CI 0.896, 1.090; p=0.81). CONCLUSION: There appears to have been a threshold in these studies of approximately 1,000 words. Questionnaires above the threshold had lower response rates than those below it (38.0% vs. 59.4%).

Developing an illustrated version of the Consumer Assessment of Health Plans (CAHPS).

BACKGROUND: The most commonly used tool for assessing member satisfaction with health plans in the United States is the Consumer Assessment of Health Plans (CAHPS). Yet its complexity exceeds the abilities of many patient populations. An illustrated version of the CAHPS instrument was designed for low-literacy audiences; the illustrations were tested and were then revised toreflect respondents' feedback. METHODS: Ilustrattions were developed to support the central themes in each of 63 CAHPS text items. The cognitive testing approach was used to create a systematic method to analyze key features of an item and develop the corresponding interview procedure. RESULTS: Following cognitive interviews on subsets of illustrations and items with more than 900 patients, all but 7 (11%) of the 63 items met the criterion that no more than 25% of the sample who saw the illustration could be rated as having "limited/no understanding." By the final pilot, a median of 66% had "full understanding," 20% had "partial understanding," and 14% had "limited/no understanding" of the 43 illustrations needing revision. CONCLUSIONS: The protocol helped improve the respondents' understanding of the illustrations. The experiences and lessons learned can guide design of illustration-enhanced materials for low-literacy populations.

Determinants of transplant surgeons' willingness to provide organs to patients infected with HBV, HCV or HIV.

The common provision of organs to patients infected with hepatitis B virus (HBV) and hepatitis C virus (HCV), but not to those infected with human immunodeficiency virus (HIV), has been attributed to perceived or real differences in transplantation efficacy among these populations. However, other explanations remain possible. We surveyed all active U.S. transplant surgeons to identify determinants of their views of the propriety of transplantation among HBV-, HCV-, and HIV-infected patients. The 347 surgeons (56.1%) returning completed questionnaires believed that HCV- and HIV-infected patients have similar post-transplant survival (p = 0.9), but that both groups fare worse than HBV-infected patients (p < 0.00001 for both comparisons). Most transplant surgeons considered HBV- and HCV-infected patients to be appropriate transplantation candidates (p = 1.0 for this comparison), whereas one-third considered HIV-infected patients to be appropriate candidates (p < 0.00001 when compared with HBV- or HCV-infected patients). That surgeons are generally willing to transplant HCV-infected patients but not HIV-infected patients, and yet believe these groups will have similar post-transplant survival, suggests that survival estimates alone do not explain surgeons' choices. HIV-infected patients should have equal access to organs unless or until evidence emerges that they fare substantially worse than other potential recipients.

Empirical assessment of whether moderate payments are undue or unjust inducements for participation in clinical trials.

BACKGROUND: Paying patients to participate in clinical trials is ethically controversial. However, there has been no empirical documentation regarding whether payment represents an undue or unjust inducement. METHODS: To evaluate these questions, we described hypothetical placebo-controlled trials of a new antihypertensive drug to 126 patients with mild-to-moderate hypertension recruited from hypertension and general medicine clinics at a university hospital. Using a 3 x 3, within-subjects design, we altered a risk to participation (either adverse effect rate or rate of randomization to placebo) and the payment participants would receive ($100, $1000, and $2000) and asked patients to indicate their willingness to participate (WTP) in each trial using a 6-point scale. RESULTS: Clustered ordinal logistic regression models revealed that patients' WTP decreased with higher risk of adverse effects (P<.001), higher risk of being assigned to placebo (P =.02), and lower payment level (P<.001). There were no significant interactions between payment level and either risk variable, suggesting that increasing payments do not alter peoples' perceptions of risk. There was a trend toward a positive interaction between income and the influence of payment on WTP (P =.09), suggesting that payment more strongly influences WTP among wealthier people. Wealthier patients were more likely to state that payment was important in their participation decision (37% vs 20%, P =.05). CONCLUSION: Although higher payment motivates research participation, we found no evidence that commonly used payment levels represent undue or unjust inducements.

Altruism, incentives, and organ donation: attitudes of the transplant community.

OBJECTIVES: This study investigated the attitudes of the transplant community toward the current policy of altruistic organ donation and 6 alternative policies offering incentives to the donor family. METHODS: Two hundred forty-nine transplant surgeons, 143 transplant coordinators, and 134 critical-care nurses rated the moral appropriateness and success of the current policy of altruistic donation, rated the moral appropriateness of the alternative policies, judged whether donation would increase or decrease under each alternative policy, and decided whether each alternative policy should be put into effect. RESULTS: All 3 professions believed the current policy of altruistic organ donation to be morally appropriate and most of the alternative policies to be morally appropriate or morally neutral. All 3 professions believed the current policy to be at best only moderately successful and judged most or all of the alternative policies to be likely to increase donation. All 3 professions favored implementing a policy offering donor recognition; approximately one half of the surgeons and one half of the coordinators also advocated implementing a policy offering 1500 US dollars toward funeral expenses. In all 3 professions, respondents' decisions to implement the alternative policies were more frequently related to those policies' moral appropriateness than to their likelihood of increasing organ donation. CONCLUSIONS: Specific incentives varied in their acceptability to the transplant community. Attitudes of the transplant community toward incentives were not in accord with published criticisms of incentives.

Do unmet expectations for specific tests, referrals, and new medications reduce patients' satisfaction?

BACKGROUND: Patient-centered care requires clinicians to recognize and act on patients' expectations. However, relatively little is known about the specific expectations patients bring to the primary care visit. OBJECTIVE: To describe the nature and prevalence of patients' specific expectations for tests, referrals, and new medications, and to examine the relationship between fulfillment of these expectations and patient satisfaction. DESIGN: Prospective cohort study. SETTING: VA general medicine clinic. PATIENTS/PARTICIPANTS: Two hundred fifty-three adult male outpatients seeing their primary care provider for a scheduled visit. MEASUREMENTS AND MAIN RESULTS: Fifty-six percent of patients reported at least 1 expectation for a test, referral, or new medication. Thirty-one percent had 1 expectation, while 25% had 2 or more expectations. Expectations were evenly distributed among tests, referrals, and new medications (37%, 30%, and 33%, respectively). Half of the patients who expressed an expectation did not receive one or more of the desired tests, referrals, or new medications. Nevertheless, satisfaction was very high (median of 1.5 for visit-specific satisfaction on a 1 to 5 scale, with 1 representing "excellent"). Satisfaction was not related to whether expectations were met or unmet, except that patients who did not receive desired medications reported lower satisfaction. CONCLUSIONS: Patients' expectations are varied and often vague. Clinicians trying to implement the values of patient-centered care must be prepared to elicit, identify, and address many expectations.
