Importance Physicians' views about health care costs are germane to pending policy reforms. Objective To assess physicians' attitudes toward and perceived role in addressing health care costs. Design, Setting, and Participants A cross-sectional survey mailed in 2012 to 3897 US physicians randomly selected from the AMA Masterfile. Main Outcomes and Measures Enthusiasm for 17 cost-containment strategies and agreement with an 11-measure cost-consciousness scale. Results A total of 2556 physicians responded (response rate = 65%). Most believed that trial lawyers (60%), health insurance companies (59%), hospitals and health systems (56%), pharmaceutical and device manufacturers (56%), and patients (52%) have a “major responsibility” for reducing health care costs, whereas only 36% reported that practicing physicians have “major responsibility.” Most were “very enthusiastic” for “promoting continuity of care” (75%), “expanding access to quality and safety data” (51%), and “limiting access to expensive treatments with little net benefit” (51%) as a means of reducing health care costs. Few expressed enthusiasm for “eliminating fee-for-service payment models” (7%). Most physicians reported being “aware of the costs of the tests/treatments [they] recommend” (76%), agreed they should adhere to clinical guidelines that discourage the use of marginally beneficial care (79%), and agreed that they “should be solely devoted to individual patients' best interests, even if that is expensive” (78%) and that “doctors need to take a more prominent role in limiting use of unnecessary tests” (89%). Most (85%) disagreed that they “should sometimes deny beneficial but costly services to certain patients because resources should go to other patients that need them more.” In multivariable logistic regression models testing associations with enthusiasm for key cost-containment strategies, having a salary plus bonus or salary-only compensation type was independently associated with enthusiasm for “eliminating fee for service” (salary plus bonus: odds ratio [OR], 3.3, 99% CI, 1.8-6.1; salary only: OR, 4.3, 99% CI, 2.2-8.5). In multivariable linear regression models, group or government practice setting (β = 0.87, 95% CI, 0.29 to 1.45, P = .004; and β = 0.99, 95% CI, 0.20 to 1.79, P = .01, respectively) and having a salary plus bonus compensation type (β = 0.82; 95% CI, 0.32 to 1.33; P = .002) were positively associated with cost-consciousness. Finding the “uncertainty involved in patient care disconcerting” was negatively associated with cost-consciousness (β = -1.95; 95% CI, -2.71 to -1.18; P < .001). Conclusion and Relevance In this survey about health care cost containment, US physicians reported having some responsibility to address health care costs in their practice and expressed general agreement about several quality initiatives to reduce cost but reported less enthusiasm for cost containment involving changes in payment models.

The pathologic changes associated with hyperthyroidism (adenomatous hyperplasia, adenoma of the thyroid gland) have been well characterized in cats, but the pathogenesis of these changes remains unclear. In this research, we undertook a case-control study to search for potential risk factors for this disease. Owners of 379 hyperthyroid and 351 control cats were questioned about their cats' exposure to potential risk factors including breed, demographic factors, medical history, indoor environment, chemicals applied to the cat and environment, and diet. The association between these hypothesized risk factors and outcome of disease was evaluated by conditional logistic regression. Two genetically related cat breeds (ie, Siamese and Himalayan) were found to have diminished risk of developing hyperthyroidism. Cats that used litter had higher risk of developing hyperthyroidism than those that did not. Use of topical ectoparasite preparations was associated with increased risk of developing hyperthyroidism. Compared with cats that did not eat canned food, those that ate commercially prepared canned food had an approximate 2-fold increase in risk of disease. When these 4 variables (breed, use of cat litter, consumption of canned cat food, and use of topical ectoparasite preparations) from the univariate analysis were selected for further study as candidate risk factors and analyzed by multivariate conditional logistic regression, a persistent protective effect of breed (ie, Siamese or Himalayan) was found. In addition, results suggested a 2- to 3-fold increase in risk of developing hyperthyroidism among cats eating a diet composed mostly of canned cat food and a 3-fold increase in risk among those using cat litter. In contrast, the use of commercial flea products did not retain a strong association. The results of this study indicate that further research into dietary and other potentially important environmental factors (eg, cat litter) is warranted.

Hyperthyroidism was first reported in cats less than 20 years ago, 1-3 and is recognized today as the most common endocrinopathy in cats. 4 Although the pathologic changes associated with hyperthyroidism (adenomatous hyperplasia, adenoma of the thyroid gland) have been well characterized, 5,6 the pathogenesis of these changes remains unclear. It has been postulated that immunologic, infectious, nutritional (eg, iodine), environmental (eg, toxins or goitrogens), or genetic factors may interact to cause pathologic changes.6-8 However, a substantial difficulty with any of these factors is how they could cause disease to develop in cats on different continents within a relatively short period of time. It also has been suggested that the disease may not be new, but instead is simply being diagnosed more frequently as cats live longer and as owners seek more geriatric care. [6][7][8] Regardless of whether the disease is new or long-standing, cats are 1 of the few species other than humans in Davis, ...
