Outcomes Assessment in Health Care Reform: Promise and Limitations
Published online by Cambridge University Press: 24 February 2021
Extract
If the fundamental goals of the health care reform effort are to ensure universal access to an acceptable quality of health care at an affordable cost, then the threshold question for reform is: What health care services should be provided in an efficient, equitable system?
Answering this question requires weighing a complex mix of medical and social policy factors, a process not attempted in this article. But the starting point for that process should be determining what health care services “work” and what they cost. Outcomes assessment holds considerable promise in finding answers to these subsidiary questions, because it is intended to assess the effectiveness of health care services, that is, what works and what does not work for patients. It holds promise, not only for improving the quality of care, but also for identifying unnecessary or wasteful practices that increase health care costs.

24 For example, lung surfactants appear to help save the lives of newborns with premature lungs. Some of these newborns who would have died several years ago now survive with other severe medical conditions that require costly medical and social services.
25 Antibiotics, for example, can cure a bacterial infection like pneumonia, but have no effect on a viral illness that produces similar symptoms. Diagnostic tests can pinpoint the cause of illness and whether an antibiotic should be used. This should benefit the patient because inappropriate antibiotic use can sometimes create resistance. However, the cost of the diagnostic tests may exceed the cost of the inappropriate use of antibiotics.

38 The ability to communicate with a physician or other provider can make possible the identification of critical information about the patient's medical history or preferences that affect diagnostic and treatment choices.

45 The number of medical procedures covered by mandated benefit laws is increasing, perhaps because patients see such laws as their only avenue to obtain specific services that private insurers would not otherwise cover. A recent example is mandated benefit laws requiring coverage of bone marrow transplants to treat metastatic breast cancer, which many women see as their last chance for survival, but which remains investigational.

48 42 U.S.C. § 139d(l)-(5) (1988) (inpatient hospital, outpatient hospital, other laboratory and x-ray, skilled nursing facilities, periodic screening and diagnosis, family planning, and physician services). States may fund additional services on their own initiative. The preamble to the Medicaid legislation states that its purpose is to enable the states, “as far as practicable,” to furnish medical care to those “whose income and resources are insufficient to meet the cost of necessary medical services… . “ 43 U.S.C. § 1396. This language identifies the individuals who are (subject to additional requirements) eligible for Medicaid, and does not necessarily entitle them to all services that are medically necessary. Neither the federal statute nor regulations defines medically necessary services.

56 Goodman v. Sullivan, 891 F.2d 449 (2d Cir. 1989). Guidelines issued to Medicare intermediaries define an experimental service as one that has not become generally accepted by the professional medical community as an effective and proven treatment for the condition for which it is being used, or one that is rarely used, novel or relatively unknown. If a service is not generally accepted, it can be deemed medically necessary if “authoritative evidence” demonstrates that it is safe and effective.
57 Hall & Anderson, Models of Rationing. Analogous disputes arise over excluding a service because it is “cosmetic” as opposed to “reconstructive” surgery, “custodial” as opposed to “skilled” care, or intended to treat “mental” as opposed to “physical” illness.

65 This conflict of interest is lessened where insurers provide only claims administration services (as by contract to self-insured employers, for example) for which they receive a fixed fee and are not at risk for payment of the benefits. However, to the extent that the insurer's income depends upon maintaining its contract fees, it has an incentive to minimize the benefits its clients have to pay.

72 In Wickline, Lois Wickline claimed that California's Medi-Cal program had wrongfully denied her extra days in the hospital which resulted in the amputation of her leg. Id. at 662. The court made clear that her physicians retained primary responsibility for patient care decisions. Since Wickline's physicians decided to discharge her without protesting or appealing Medi-Cal's refusal to pay for an additional hospital stay, Medi-Cal was not liable for her loss. Id. at 670-71. Medi-Cal made a decision on payment only. However, the court hinted, in dictum, that third party payors “can be held legally accountable when medically inappropriate decisions result from defects in the design or implementation of cost-containment mechanisms ….” Id. at 670.

Some Congressmen have proposed amending ERISA to overrule Pilot Life to allow employees to pursue rights of action under state statutory and common law, such as those for fraud and bad faith in withholding insurance benefits. See, e.g., S.794, 102d Cong., 1st Sess. (1991) (entitled The ERISA Preemption Amendments of 1991); H.R. 6147, 102d Cong., 2d Sess. (1992) (entitled Group Health Plan Nondiscrimination Act of 1992).
75 ERISA also permits injunctive relief which might ensure that necessary care be provided in the future, but may come too late to help a patient who has already been denied care.

79 Competing insurers or hospitals might collaborate to develop more consistent practice policies, but in so doing might be accused of engaging in a combination or conspiracy in restraint of trade in violation of the antitrust laws. To the extent that such practices are considered part of the business of insurance, they may be exempt from antitrust challenge. In practice, institutions that make independent judgments face little likelihood of antitrust complaints.

81 Such standards have been held not binding on a patient where the private insurance contract did not expressly specify the entity or standard. Pirozzi v. Blue Cross and Blue Shield of Va., 741 F. Supp. 586, 588-89 (E.D. Va. 1990).

83 It also creates an incentive for physicians and patients to characterize recommended services as services that are covered by the plan, which may produce fraudulent claims. Dennis, Novak et al., Physicians'Attitudes Toward Using Deception to Resolve Difficult Ethical Problems, 261 JAMA 2980, 2981-84 (1989)Google Scholar.
84 This is the practice in Canada, where the government pays physicians on a fee-for-service basis, with fees negotiated with government by medical societies. Total fees are reviewed annually and adjusted prospectively if necessary to keep within provincial budget limits.
85 This is the approach adopted in President Clinton's Health Security Act, S. 1757, H.R. 3600, 139 Cong. Rec. S16.788 (daily ed. Nov. 20, 1993). The single payer alternative sponsored by Senator Wellstone and Representative McDermott and others would also establish a uniform minimum benefit package, but would not require the involvement of insurers.
86 Mandatory uniform benefit plans would preclude people from being able to buy a very cheap health insurance policy, being misled into foregoing important benefits, or remaining uninsured or “underinsured” while healthy. Although some economists might consider this an encroachment on individual freedom, it is no more of a limitation than the restrictions on available products imposed by drug regulation, environmental protection standards, and other consumer safety laws.

89 The plaintiff must provide expert evidence, usually in the form of testimony by a physician-witness, of what a reasonably skilled physician would do for a patient in similar circumstances. The same principle applies to other practitioners, such as nurses, dentists, and hospital administrators, who are held to the level of skill exercised by a competent practitioner in the same field. The defendant may, and does, offer opposing expert testimony that a different standard of care applies, and that whatever the defendant did or did not do satisfied the applicable standard of care or at least a respectable minority position within the medical community.
