Definition/Introduction
Managed care refers to a healthcare insurance approach that integrates healthcare financing and the delivery of care and related services to keep the costs to the purchaser at a minimum while delivering what is appropriate for a given patient or population.[1][2] The precise definition of managed care has evolved over several decades.[3]
Common to most definitions of managed care are several features or components, such as:
A limited network of providers (professionals such as physicians and organizations such as hospitals, imaging centers, pharmacies, and laboratories) who are each credentialed and contracted
Utilization management
Quality management
Financial incentives for the patient to use network providers
Some level of financial incentives or risk-sharing by the provider for the care provided
[1]
Managed care financial arrangements vary widely and occur from retrospective fee for service payments at one end to prospective, full financial risk-type pre-payments for each member, so-called capitation, paid monthly, as a per member per month (PMPM) capitation rate.[2][4] Between these 2 extremes are numerous variants that balance the level of retrospective payment (paid after service is delivered, ie, service fee) and prospective payment (paid before the service, ie, capitation or prepayment/PMPM).[5]
The types of managed care insurance or benefit management approaches have also evolved. Initially, managed care was synonymous with a health maintenance organization or HMO approach.[6] In the traditional HMO model, patients enrolled select a primary care provider (PCP) who receives a PMPM to provide care and coordinate all services for that patient. The PCP serves as the patient’s gatekeeper for all necessary services and must provide a referral for the patient to be seen by a subspecialist or to receive imaging or laboratory studies. The PCP is expected to manage and oversee the care so that only appropriate care and services are provided according to available evidence or consistent with standardized care pathways. Only network providers are available to the patient in an HMO, so specialists, hospitals, pharmacies, imaging centers, and laboratories are preselected, credentialed, and contracted by the HMO. In the case of an HMO with a gatekeeper model, coverage is only available for care and services authorized by their PCP.
Over time, some less traditional HMOs emerged where the PCP does not serve as the gatekeeper, and the patient may self-referral to a specialist. However, for the service to be covered and paid for by the managed care plan, the patient is still limited to only receiving care and service from network providers. HMOs' utilization and quality management programs collect much data on the care and services authorized and provided by the PCP and other providers. This data is communicated to the PCP and other network providers regularly as the financial incentives revolve around compliance with the managed care plan’s utilization and quality programs’ targets. For the patients, the financial incentive is that they receive insurance coverage only for services that occur within the network.
Not all managed care occurs via an HMO-type arrangement.[2] Due to the patient’s desire to have more provider choices than would be available either in the gatekeeper or non-gatekeeper type HMO, and in part due to the provider's complaints about the loss of autonomy in HMO type arrangements, the preferred provider organization (PPO) emerged. In this managed care approach, the insurance company recruits a network of providers in a given geographic region, including both PCPs and subspecialists, along with a set of hospitals, pharmacies, imaging centers, and laboratories who all agree to take a discounted rate in exchange for the opportunity to be listed as in-network and potential be selected by a relatively large group of patients to be their provider. The providers are held to utilization and quality targets. The providers bear some level of financial risk for the population of patients they serve, mostly competing for incentive payments based on utilization and quality performance. Patients have more autonomy in making care decisions related to selecting subspecialty providers than in an HMO. However, they are still limited to receiving care from in-network providers. However, the network is likely more extensive than the one available in the HMO setting.
Finally, in this vein of patients wanting more choices, a point of service (POS) managed care arrangement has emerged, which may appeal to more discretionary income patients. In a POS plan, the patient may use this managed care plan like a PPO and remain to limit their choices to only in-network providers and thus maximize their coverage. However, in a POS, the patient may choose to see a provider outside of the network, which incurs more cost-sharing on the patient’s part. Thus, in a POS arrangement, patients may see any provider they choose, either in-network or out-of-network. Still, if they stay within the PPO network, they pay the least, but they share a higher portion of the care cost and pay more if they go outside the network.
Issues of Concern
When discussing managed care, the overriding concern is the intermingling of the provider's finances with the amount and type of care they offer to the patient.[1][7] In the traditional gatekeeper HMO-type arrangement, the type and amount of care and service the patient provides directly connect to the provider's financial well-being. In a prospective prepayment full capitation model, if, on average, the provider gives more care and service to the patient than is called for by the targets set by the HMO (ie, high utilization or overuse), then the provider has a financial loss. On the other hand, if, on average, the provider gives less care and service than stipulated by the targets set by the HMO (ie, low utilization or underuse), then the provider would have a financial gain. Guardrails established by the plans mitigate this extreme dichotomy. Expected levels of preventive care that must be delivered with the use of risk adjustment techniques to allow higher expected utilization for patients with chronic conditions such as diabetes or congestive heart failure, which would be expected to need more care and service when compared to a healthy young patient with no medical diagnoses. Ideally, managed care aims to deliver only appropriate care and settle in the middle of the 2 extreme situations described above. The optimal managed care plan would be one where the provider offers the optimal, appropriate amount of care and service to each patient, then averages out across all the enrolled patients being cared for by that provider and is financially beneficial for the provider and clinically appropriate for the patient.
Another concern that emerges with managed care is the perception of a lack of professional autonomy and the obligate burden or hassle factor that arises for the provider who must function in a more structured monitored environment and receive, analyze, and act upon utilization and quality reports sent to them from the teams at the managed care plan.[1][4] This added administrative burden inevitably adds to the provider’s administrative costs and is associated with a lessening sense of professional fulfillment on the part of the providers and is, in part, associated with a growing sense of burnout and lack of satisfaction being reported by providers.[5]
As experience with managed care becomes established in the health care setting, a concern arises around the risk that patient access may be limited by providers gaming the system and cherry-picking or seeking to serve only patients in one’s practice that are likely to be healthier, more likely to need less care and service and thus who would make it easier to meet the utilization and quality targets.[4][8]
This gaming or cherry-picking would leave patients with chronic conditions or some level of medical complexity with less access to care because fewer providers would be available and willing to see them in their practices. If this gaming occurs, providers motivated to care for patients with chronic conditions or medical complexity would be financially disadvantaged by merely doing the right thing and making themselves available to those most in need of healthcare. Recognizing this potential disincentive, managed care plans mitigate this potential by risk-adjusting their measures and targets so that expected higher utilization that reflects appropriate care for a patient with a chronic condition is factored into the target setting. This risk adjustment accommodates providers who take on the added responsibilities of caring for a more chronically affected patient population.
Clinical Significance
Managed care was introduced to decrease overspending on patient care and the oversupply of healthcare services.[3][9] Various studies have shown the differences between fee-for-service and managed care. In a well-done comparative study over 10 years conducted in Switzerland, managed care produced substantial and sustainable cost savings to the healthcare system with significant decreases in inpatient mortality, hospitalizations, and length of stay.[10] In this analysis, the cost savings were driven by fewer subspecialty consultations for patients enrolled in managed care plans and shorter lengths of stays for those admitted to a hospital, which produced improved care measures.[10]
Like any other industry, healthcare has commercialized over the decades; thus, cost-cutting has met with continued backlash. This has given rise to managed competition, which offers the consumer full responsibility to choose the premium costs and overall health care coverage and adjust the care plan based on personal risk. This has helped incentivize physicians to provide better care with controlled costs.[11] In essence, managed care was designed to help centralize health care, contain patient costs, improve resource utilization, and improve patient quality of care. Over time, managed care seems to achieve these goals but still has a way to go before realizing its full potential.[11][12] However, it is still estimated that nearly 25% of healthcare spending in the US is wasted.[11]
Nursing, Allied Health, and Interprofessional Team Interventions
Clinicians in the managed care plan perform utilization and quality management functions, including:
Collecting the clinical information required for utilization and quality management activities
Helping providers interpret the clinical relevance and appropriateness of the information being shared to the practice.
Collecting and interpreting clinical information related to medication use
[13][14][15][13]
To help resolve some of the challenges associated with managed care and the interaction with providers delivering care to patients, the Academy of Managed Care Pharmacy Professional Practice Committee has determined 9 concepts to strengthen the relationship between the provider and pharmacist. The organization also improves patient outcomes and mitigates resource use through utilization management criteria, keeping patient safety in mind with clinical decision-making through evidence-based review, providing transparent patient care without any roadblocks in therapy, and facilitating collaboration.[16]
