Hospitalists typically work in shifts; therefore, within the same hospital, patients treated by hospitalists are plausibly quasi-randomized to a given physician based
on when patients become sick and based
on hospitalists» work schedule.34 We defined hospitalists using a validated approach: general internists who filed at least 90 % of their total evaluation and management
billings in an inpatient setting.35 Second, to evaluate whether our findings were sensitive to how we attributed patients to physicians, we tested the following 2
alternative attribution
methods: attributing patients to physicians who had the largest number of evaluation and management claims and attributing patients to physicians who
billed the first evaluation and management claim for a given hospitalization.25, 36,37 Third, within some hospitals, male internists may be more likely to work in intensive care units and have severely ill patients.
Henry apparently finds that option too radical, and therefore unrealistic (to be sure, while it would be ideal for firms to develop
alternative methods of charging for their services that eliminate the billable hour, the fact remains that law is a business and
alternative methods of
billing have to make economic sense given the nature of practice areas such as litigation where one's adversary has the power to determine how much time one will have to spend
on a case).
