Older persons’ evaluations of health care: the effects of medical skepticism and worry about health - Patient Assessments
Categories: medical billing systemConsumer assessments have become an important tool for monitoring the accessibility and quality of health services. Health plans and systems routinely conduct consumer evaluations to monitor their performance and alter the delivery of care in order to retain and attract customers (Maciejewski, Kaweicki, and Rockwood 1997). Clinicians use consumer or patient satisfaction ratings to determine how they can better meet the needs of patients and, potentially, improve patient compliance (Sherbourne et al. 1992) and treatment outcomes (Kane, Maciejewski, and Finch 1997; Smith 2000). Finally, purchasers of health insurance plans such as employer groups and consumers themselves sometimes examine ratings when deciding which plan to choose (Farley et al. 2002; Spranca et al. 2000).
Consumer ratings are, of course, subjective and thus may be influenced by various demographic, social, and health status factors. Health status has been shown to be correlated with consumer satisfaction, with persons in poorer health tending to have lower ratings (Aharony and Strasser 1993; Hall, Milburn, and Epstein 1993; Kane, Maciejewski, and Finch 1997; Lee and Kasper 1998; Rubin 1990; Smith 2000). Other research suggests that demographic factors, such as gender and age (Locker and Dunt 1978; Nelson-Wernick et al. 1989), as well as socioeconomic factors, such as educational attainment and income (Lee and Kasper 1998), are associated with evaluations. In the largest study to date of ratings by Medicare managed care beneficiaries, Zaslavsky and colleagues demonstrated that health status, age, education, and interactions between region and health and education, respectively, were important case-mix adjusters (Zaslavsky et al. 2001).
Other individual differences, including attitudes about health care, may affect consumer assessments. Donabedian points out in his discussion of quality that satisfaction is party a function of individual as well as societal expectations (Donabedian 1988). Expectations can be shaped by a variety of experiences with previous medical care as well as deeply held attitudes. One concept that may capture such attitudes is skepticism toward medical care. Medical skepticism has been shown to be predictive of fewer physician visits, a lack of a usual physician, lower use of hospital care, and lower health care expenditures (Fiscella, Franks, and Clancy 1998) as well as mortality (Fiscella et al. 1999). A logical extension of these findings is the hypothesis that consumers shape a cognitive evaluation of their health care that conforms with their skeptical attitudes. In other words, consumers who are skeptical about medical care would be expected to have worse evaluations of health services as compared to those who are not skeptical.
In addition to attitudes about medical care, other individual differences may help to explain variation in ratings. As mentioned earlier, health status has been shown to be associated with satisfaction, but there are countess ways of assessing health. Measures of the presence/absence of disease are frequently available either from billing data or clinical records and can be merged with consumer assessment data. Perceived health-related quality of life measures, such as the Short-Form 12 (SF-12) (Ware, Kosinski, and Keller 1996) are sometimes used to control for differences in health. An additional brief measure that has the potential to reflect health status and affect the degree to which individuals evaluate their health care is their worry about their own health. Worry about health status has been shown to be predictive of greater utilization of medical services among the elderly, but has not been studied to determine if it associated with evaluations (Wolinsky and Johnson 1991).
The primary purpose of the present paper was to examine whether medical skepticism and worry about health affect overall care ratings (OCR) and personal doctor ratings (PDR) among the noninstitutionalized elderly, or persons aged 65 years and older, a group that has gone relatively understudied as compared to the general population of adults (Lee and Kasper 1998). Global ratings of care, such OCR and PDR, reflect multiple dimensions of satisfaction with care (Cleary and McNeil 1988), rather than specific dimensions of the quality or accessibility of services, and are used to make summary judgments and comparisons of health services across health plans or health systems. Specific hypotheses tested were:
H1: Elders who are skeptical about the benefits of medical
care have lower OCR and PDR than those who are not skeptical
H2: Elders who worry about their health have lower OCR and PDR
than those who do not worry about their health.
METHODS
Study Design and Setting
The study was conducted in a southwestern region of the United States, the 105 counties comprising West Texas, an area stretching between the U.S.-Mexican border on the west, the cities of Wichita Falls and Abilene on the east, the Texas Panhandle on the north, and the Permian Basin region on the south. Data were collected through a telephone survey of some 5,000 community-dwelling elders’ health status, health care accessibility and quality, and other health-related factors. Telephone surveys are frequently conducted to assess consumer satisfaction, and their suitability has improved in recent years. Within Texas, only 4.18 percent of households are estimated to have no telephone service available (U.S. Census Bureau 2000a). Comparisons of estimates from the National Health Interview Survey between all households and households with telephones indicated very small (less than 1 percent) differences in health-related variables (Anderson, Nelson, and Wilson 1998).
