In a recent paper in Health Economics, Stevens, McCabe and Brazier (Health Econ. 2006; 15: 527-533.) found that the cubic relationship between Visual Analog Scale (VAS) values and standard gamble (SG) utilities was superior to other functional forms in terms of explanatory power and predictive ability. Consequently, they question the reliance on the assumption of a power curve relationship, which was established, theoretically and empirically, in earlier works. This note argues that: (1) SMB's conclusions are incorrect. The estimated cubic function overfits the four data points, and is questionable with respect to the implied attitude toward relative risk. (2) The evaluation of the functional forms in terms of the individual predictions' mean absolute error is misleading and (3) correcting for heteroscedasticity improves the precision of the estimates and of the predictions.
Nurse executives are aware of the complexities of organizational culture. It impacts the nursing work environment and patient care safety and quality. The authors describe several widely available tools that nurse leaders can use to assess organizational culture in the work environment. The psychometric and conceptual strengths and weaknesses of the measures are described and recommendations for use in nursing and patient care administration are provided.
