Managed care

Implications of managed care for health systems, clinicians, and patients

Gillian Fairfield, David J Hunter, David Mechanic, Flemming Rosleff

This is the second in a series of three articles aiming to raise understanding of the issues surrounding managed care

Summary

The rhetoric and realities of managed care are easily confused. The rapid growth of managed care in the United States has had many implications for patients, doctors, employers, state and federal programmes, the health insurance industry, major medical institutions, medical research, and vulnerable patient populations. It has restricted patients' choice of doctors and limited access to specialists, reduced the professional autonomy and earnings of doctors, shifted power from the non-profit to the for-profit sectors and from hospitals and doctors to private corporations. It has also raised issues about the future structuring and financing of medical education and research and about practice ethics. However, managed care has also accorded greater prominence to the assessment of patient satisfaction, profiling and monitoring of doctors' work, the use of clinical guidelines and quality assurance procedures and indicated the potential to improve the integration and outcome of care.

Implications of managed care for health systems

Managed care in the United States has grown because it allows employers and public health programmes to purchase services for its clients at lower cost than traditional insurance. The growth of a competitive market and increased purchasing expertise has allowed private and public purchasers to contain the growth in premium costs and in some instances to reduce them.(2) However, a major difficulty in controlling costs is establishing capitation rates that adjust appropriately for projected morbidity and utilisation of care by patient populations. Managed care plans that enrol healthier patients make large profits while those attracting a disproportionate number of high risk patients can incur large losses. This undermines the goal of having plans compete on price and quality rather than success in selecting low risk patients. Attempts to control selection by risk include open enrolment periods, marketing rules, supervising enrollee choice, and federal legislation restricting the exclusion of people with pre-existing conditions.

Managed care companies are able to reduce costs by negotiating aggressively with hospitals and provider groups on rates and use of expensive resources such as inpatient care. Several sources report decreased utilisation of health services and decreased lengths of inpatient stays by managed care organisations.(3-5) This may reduce the demand for hospital beds and decrease hospital revenues, with the result that hospitals downsize and even close. Similarly, organised managed care networks need fewer specialists; by using primary care gatekeepers (who may have financial incentives to manage patients themselves) they shift power from specialists to general practitioners. As hospital and outpatient clinics are required to function more efficiently and at less cost, it remains unclear who will reimburse the higher costs of medical and other professional training, research, and patient care associated with new experimental treatments that do not fall within the managed care definition of "necessary care."

Implications of managed care for health systems
Positive:

Better outcomes

Lower cost

Better quality (evidence based medicine)

Improved allocation of resources

Seamless care
Negative:

Increased costs and time

Need to overcome resistance to change

Block to innovation

Research and education at risk

Vulnerable populations at risk

Though the evidence suggests that outcomes with managed care in general are no worse than with traditional fee for service, and may in some aspects be better,(5) some studies suggest that health maintenance organisations may have worse outcomes in treating elderly and poor patients with chronic illness; this may result in calls for regulation.(6) The lead in independent scrutiny of the quality of care provided by managed care organisations in the United States has been taken by the National Committee for Quality Assurance, a not for profit organisation partly financed by health maintenance organisations.(7)

Regulation and continuing scrutiny of managed care are emerging in three ways. Firstly, the United States congress and many state legislatures are passing laws to limit some managed care practices, such as mandatory early discharge (less than 24 hours) - for example, for mothers after giving birth - or to prohibit "gag rules" that restrict what doctors can tell their patients. Secondly, state departments of health and state insurance departments are issuing regulations on disclosure of financial incentives, mechanisms to settle complaints, required independent review of contested denials of service, and on matters such as whether non-medical reviewers of care can deny provision of medical service. Thirdly, the federal Health Care Financing Administration has also issued detailed managed care regulations affecting enrollees in government funded Medicare and Medicaid programmes.

Implications for clinicians

Within a system of managed care, doctors may experience decreased autonomy or lack of clinical freedom (box). Alternatively, they may derive satisfaction from working with guidelines within evidence based medicine and enjoy increased professionalism from knowing that their practices are operating to high standards.

Iglehart points out that by participating in managed care, doctors are showing a willingness to adapt to situations in which their actions may be curtailed and their accountability increased.(8) However, this willingness may be a result of the fact that work within managed care may be preferable to no work at all.

Implications of managed care for doctors
Positive:

Increased professionalism

Collaboration

Better information
Negative:

Reduced clinical freedom

Reduced status

Increased supervision

Conflicts of interest

Altered doctor-patient relationship

One of the powerful mechanisms underpinning managed care is the use of guidelines; either to pre-authorise care, manage ongoing treatment and length of stay, or for managing complex, high cost cases. Though often written and approved by doctors, these guidelines are usually administered by managers or nurses, curtailing some of doctors' freedoms - but doctors retain ultimate responsibility for patient care. The implications for doctors depend on the quality of the guidelines and how and by whom they are applied.

Incentives that encourage doctors to practice cost effectively include risk sharing, performance related payment, and bonuses and withholds.(9) Although use of hospital resources can be reduced by payment incentives - sharing resource utilisation information with clinicians, and formal utilisation strategies(10) - financial incentives are key to explaining low utilisation rates.(11) Financial incentives may undermine the doctor-patient relationship as they may result in management plans which are hidden from the patient. Conflict may arise if the doctor does not disclose incentives not to treat or fully explain treatment options. The ethical basis of many practices of managed care companies has been questioned: for example, putting more than small amounts of the providers' personal remuneration at risk should utilisation targets be exceeded; enforcing gag rules that limit what doctors can tell patients; and taking arbitrary decisions affecting patients and doctors without adequate appeals mechanisms.(12)

Managed care has implications for doctors by virtue of the means by which they are selected to become providers. Doctors not performing to standard, however defined, may be deselected. Their success can be judged on clinical criteria, commitment to the organisation, patient satisfaction, office organisation, case management of high cost patients, communication between primary and secondary care, length of stay, and delivery of preventive services.

"I used to be a doctor"
I used to be a doctor
now I am a Health Care Provider
I used to practise medicine
now I function under a managed care system
I used to have patients
now I have a consumer list
I used to diagnose
now I am approved for one consultation
I used to treat
now I wait for authorisation to provide care
. . . .
I used to have a successful people practice
now I have a paper failure
I used to spend time listening to my patients
now I spend time justifying myself to the authorities
I used to have feelings
now I have an attitude
Now I don't know what I am
(Found on the internet)

How, why and by whom should a doctor be considered inadequate? The concern is that managed care companies use profiling to deselect the high cost doctors rather than those providing poor quality care. Standards, case mix variables, and appeals procedures therefore need to be transparent, which has not always been the case in the United States. Increased accountability, utilisation management, and physician profiling all require better information systems, without which the long term evaluation of outcomes would prove impossible.

Many procedures are being removed from doctors and placed in the hands of other professionals, such as psychologists and optometrists, who have become preferred providers. Doctors are required to work in a more multidisciplinary manner and relinquish some control. Although this demands a culture change there are many opportunities for collaboration.

The feelings of United States clinicians towards managed care have included anger, denial, depression, negotiation, and finally acceptance. Doctors are often pulled between competing loyalties and tend to resist cost control measures because they suspect the motives of the managers. A poem taken from the internet (box) may represent an extreme view, but what is important is that these sentiments are expressed at all. If clinicians in the United States perceive managed care negatively, initiatives in Britain may engender similar fears. How managed care is presented to, and seeks to engage, clinicians in Britain will be central to its success.

Implications for patients

Patients too surrender some of their freedom under a managed care system. They may be restricted in their choice of doctor or hospital, and guidelines may dictate primary care rather than secondary care. Decreased choice may be offset by better outcome and quality of care: better integrated systems, improved quality monitoring, and greater attention to their satisfaction. Studies of the Medicaid population indicate that managed care may allow better access and some aspects of satisfaction than do traditional fee for service plans,(13) although consumer satisfaction is generally considered to be poorer in managed care organisations. In Britain, how managed care will provide for disabled patients, who require continuing care and experienced professionals, and those with chronic disease, who require services across care areas, is of concern. The extent of the shift of burdens and costs outside the medical sector is unclear.

Potential improvements in the doctor-patient relationship include increased choice of managed care plan and physician, availability of information on physician competence and outcome, and a broader range of medical teams which include non-doctors(14) - but there may be less time for the doctor-patient interaction, fewer home visits, deselection of physicians causing disruption to continuity of care, and physician incentives causing conflict. As with the effects on clinicians, the implications for patients depend on the validity of the managed care processes, the training and skills of those involved in the process of managing care, the quality of the communications, and the constraints and incentives imposed on physicians.

Implications of managed care for patients
Positive:

Better outcomes

Better informed

Clearer expectations

Patient driven guidelines

Increased satisfaction
Negative:

Restriction of treatment or doctor

Increased responsibility not wanted

Altered doctor patient relationship

Less satisfaction

There are calls for organised consumer protection in the United States,(15) and the Council on Ethical and Judicial Affairs in the United States has recommended guidelines for managed care(16): doctors must continue to put patients first, with patient advocacy paramount. Information must be available to patients regardless of guidelines. There must be a mechanism in place to ensure arbitration and appeals by both patients and physicians. Alternative treatments must be discussed, and no gag clauses should be allowed. There should be standard limits on the amounts of fee incentives or withholds for clinicians and full disclosure to patients of those incentives.

Patients have the potential to drive managed care by being better informed and empowered. Under a seamless care system with integrated primary and secondary care, patients should receive more preventive services and take more responsibility for their own health. Measures need to be taken to ensure that it is not just the articulate middle classes that are empowered - the interests of vulnerable groups must be protected.

The NHS as a managed care organisation

Not all of the American experience is applicable to the NHS. Health care in the United States is a commodity to be bought and sold; in Britain, health care is regarded as a fundamental human right. Despite the challenges facing it, the NHS retains a population based, communitarian ethic. At a macro level, the NHS is already a managed care system with many of the requisite features in place (box).(17)

Features of the NHS as a managed care organisation
Structural features:

Limited consumer choice of general practitioner

Primary care gatekeeper

Selective contracting by purchasers

Financial incentives for general practitioners (capitation and bonuses for reaching targets, etc)
Functional features:

Quality management (audit, accreditation)

Utilisation management (guidelines, shared care protocols)

Recent white papers(18-20) developing the vision for a primary care led NHS offer the possibility of increasing both the structural and functional aspects of managed care by extending professional roles (thus increasing the range of potential preferred providers), diversifying employment and contract options, encouraging flexibility and sharing of premises, developing audit and evidence based medicine, introducing flexibility in resource use, and by encouraging information technology developments, including those in the area of clinical decision making.

Developing primary care purchasing could see the founding of structures similar to health maintenance organisations or preferred provider organisations with which health authorities could contract. Trusts and other health related bodies could employ salaried general practitioners, creating the equivalent of staff model health maintenance organisations.

The greatest potential lies at a micro level - namely, utilisation management, physician profiling, and financial incentives. With collaborative, seamless care as the goal of the NHS, key stakeholders will need to consider how risk will be distributed. Financial incentives and risks will need to be aligned to motivate all key players, yet this may prove difficult if fragmentation and diversity result in a conflict of policy objectives.

Increasing use of guidelines and utilisation management could provide a lever for the practice of evidence based medicine, which may reduce inappropriate treatment, improve quality, and decrease costs. Physician profiling could inform clinicians as to their own performance. All of these techniques will need to address two major barriers: information needs and the commitment and cooperation of doctors. Clinicians are still able to practise medicine as they see fit, and audit remains largely informal and without sanctions. This is a far cry from the United States, where managers are closely involved in clinical matters. Doctors in Britain will need to be reassured that the aim of managed care truly is to improve medicine and not direct it. If managed care comes to mean accountancy rather than accountability, doctors will resist.

Finally, a health warning: the further down the road to pluralism the NHS goes, the more difficult it will be for any government to reverse changes as there will be too many vested interests at stake to permit reform - a difficulty the United States is well aware of.
