A blueprint for high-volume, high-quality lung cancer screening that is detecting cancer earlier—and helping to save lives
Former surgeon general C. Everett Koop, MD, famously said “Drugs don’t work in patients who don’t take them.” This is exceptionally true, with potentially terrible consequences, of specialty medications.
“Medication adherence is particularly important for people who have [the severe] conditions that require the use of specialty medications,” says Thom Stambaugh, RPh, vice president and chief pharmacist for Cigna HealthCare. “We work with the member and physicians to make sure medications are taken as prescribed.”
These are often astronomically expensive medications. The average prescription cost for these medications runs more than $1,500 and some top $100,000 a year, according to Express Scripts, a large pharmacy benefit management company. Specialty-drug spending in this country could reach $99 billion by 2010, nearly double the $54 billion spent in 2006.
The cost of specialty drugs, including biotech drugs, is related to the advances in research, technology, and design that created them, and to the complexity of the treatment associated with their use. Many specialty drugs require patient-specific dosing and careful clinical management. Many are administered by injection or infusion. Some patients inject themselves; others receive their drugs at a physician’s office or outpatient clinic or through a home care service. Several newer specialty drugs, particularly those for oncology patients, are taken orally.
“Some of these products offer lifesaving and quality-improving benefits,” says John Watkins, pharmacy manager for formulary development at Premera Blue Cross in Mountlake Terrace, Wash. “The principal challenge facing public and private payers relates to affordability of these products.”
At Kaiser Permanente in California, biotech products have greatly increased drug costs, particularly in oncology, rheumatology, neurology, endocrinology, and dermatology, says C. Douglas Monroe, RPh, a drug information pharmacist with Kaiser Permanente Drug Information Services. “Some conditions that were formerly untreatable now have a single, very costly treatment available. For example, Kaiser Permanente in California spends more than $10 million annually for biotech- derived enzyme replacements to treat approximately fifty patients with various rare, inherited enzyme deficiencies that result in severe health problems and early mortality. For these patients, there are no lower-price alternatives.”
Kaiser Permanente is an integrated health system, and therefore “medication adherence is viewed as a responsibility of all care providers, working in as coordinated a process as possible,” says Monroe.
“Our providers have immediate access to pharmacy records, and for these critical and expensive drugs, adherence can be monitored through claims records. The same techniques of measuring adherence through refill rates and lab tests used for standard drugs are now starting to happen with specialty drugs, led by our ambulatory pharmacists.”
Adherence to (or compliance with) a medication regimen is generally defined as the extent to which patients take medications as prescribed by their health care providers, wrote Lars Osterberg, MD, of the Veteran Affairs Palo Alto Health Care System in Calif., in a study of adherence published in the New England Journal of Medicine. “The word adherence is preferred by many health care providers, because compliance suggests that the patient is passively following the doctor’s orders and that the treatment plan is not based on a therapeutic alliance or contract established between the patient and the physician,” says Osterberg.
For health plans, adherence is a significant element of cost containment. “It is a matter of giving the right drug to the right patient at the right time,” says Brian Sweet, RPh, chief pharmacy officer for WellPoint. “That is the definition of quality. Some plans look at the pharmacy benefit as a budget buster. We believe that quality delivered through the benefit can be a budget saver because it can reduce overall health costs.”
WellPoint’s in-house specialty pharmacy program is named PrecisionRx Specialty Solutions. “Our approach is holistic,” says Sweet. “It is a comprehensive care management approach that we have found to be very successful, with a proven track record. Given the complexity of side effects related to many treatments, we have found that an aggressive approach is crucial.”
In describing the WellPoint approach as holistic, Sweet is referring to frequent patient interactions with WellPoint nurses and pharmacists to discuss side effects and maintenance regimens with patients — followed by medical or behavioral care referrals as necessary. The interaction is usually over the telephone. “We view the interactions as clinical events, and we offer access to pharmacists 24/7 through a call line,” says Sweet.
WellPoint recently evaluated the effectiveness of its PrecisionRx Specialty Solutions approach for multiple sclerosis patients. Evaluation endpoints included medication possession ratio (a formula used to determine adherence that is measured from the first to the last prescription), therapy discontinuations, medical costs, and pharmacy costs. In all those categories, outcomes were significantly better for the managed patients. “Most notably, there was a decrease in overall MS costs when members were managed by the program,” says Sweet.
Specialty pharmacies agree on the critical importance of adherence. “Patient adherence support and education are essential for successful therapy,” says Kim Bergstrom, PharmD, chief clinical officer at McKesson Specialty Pharmacy Services, which serves all Medicare Part D plans and 120 million lives in health plans across the country. “For oncology drugs, for example, the side effects can be unpleasant, but if patients do not keep on their medications, if they don’t follow therapy carefully, they won’t benefit.”
“Many of the expensive cancer drugs emerging recently are oral, which means that patients take them at home on a timetable established by their physician,” adds Bergstrom. “This can make adherence management more complicated and difficult, and the consequences can be severe. If patients go off their drugs, they can become resistant to the medication itself. Maintaining adherence is extremely important. It can be a matter of life and death.”
The cost of the average monthly cancer-drug prescription rose 15.8 percent to over $1,800 in 2007, according to Express Scripts. Among the new specialty drugs approved by the Food and Drug Administration last year, one breast-cancer treatment costs about $2,900 a month. And according to the Wall Street Journal, these costs are rising. An oral drug for multiple myeloma, Celgene’s thalidomide (Thalomid), increased 27.2 percent to $4,742 per prescription in 2007, up from $3,728 in 2006. Roche’s oral chemotherapy drug capecitabine (Xeloda) rose 17.9 percent to $1,200 per prescription in 2007, up from $1,018 per prescription the previous year, according to a recent review of specialty drug costs in that newspaper.
Specialty medication compliance is important to manufacturers as well as health plans, says Lynn Benzing, chief executive officer of Patient Marketing Group Inc., a consultancy in Princeton, N.J., that helps drug companies develop adherence techniques.
“From a pharmaceutical manufacturer perspective, establishing effective programs to build loyalty and assure adherence among patients using biotech drugs is particularly important,” she says. Among the reasons:
Benzing lists these patient support strategies:
“Building a long-term relationship with the patient to ensure continued commitment to therapy and encourage healthy behaviors that can contribute to effective disease management is a form of value-based marketing,” adds Benzing. “These relationship marketing programs are most powerful when they are interactive and tailored to the individual patient.”
The personal relationships Benzing is referring to are essential to maintaining specialty drug compliance, say health plan officials. “Encouraging our patients to take their drugs as directed offers the very best chance for averting bad outcomes,” says Edmund Pezalla, MD, Aetna Pharmacy Management’s national medical director. “Adherence is difficult with these drugs. Many patients simply don’t like needles; many of these drugs have significant side effects; and the drugs themselves can cost patients a great deal of money. So there are significant clinical advantages to personal interventions.”
Health plans and employers adopt a variety of methods to manage specialty medications. Several health plans hire companies such as McKesson to manage these expensive drugs. Several manage the drugs in-house through their own specialty pharmacies. “Our pharmacy management program takes an approach to specialty medications that integrates medical, pharmacy, and behavioral health care to help people with these conditions better manage their care and live as productive lives as possible,” says Cigna’s Stambaugh.
Rather than placing expensive specialty drugs on a fourth formulary tier with very high co-payments, Cigna Pharmacy Management starts with “recommending benefit plan designs that set per-prescription or annual out-of-pocket limits to help minimize financial barriers to medication compliance,” says Stambaugh.
Cigna contacts patients either by postcard or phone call when prescription renewals are approaching. “We look for gaps in medication refills that could indicate someone is not taking medications appropriately and communicate with the physician and the individual to try to determine any barriers and help close those gaps in care,” says Stambaugh.
Cigna also stresses the advantage of a single claims platform for specialty drugs that allows for a strong coordination of care. “The information is shared with Cigna medical care managers so they can address any gaps in care during their regular interactions with the individual,” says Stambaugh.
With reference to specific benefit designs, Aetna also uses its entire suite of available programs. For example, multiple sclerosis patients frequently suffer from depression, says Pezalla, which can result in non-compliance. “So we make referrals to our behavioral unit as necessary,” he said.
Rates of refilling prescriptions can be an accurate measure of overall adherence in a closed pharmacy system, according to Osterberg, “provided that the refills are measured at several points in time,” he said. “A medical system that uses electronic medical records and a closed pharmacy can provide the clinician or research scientist with readily available objective information on rates of refilling prescriptions that can be used to assess whether a patient is adhering to the regimen and to corroborate the patient’s responses to direct questions or on questionnaires.
Benzing, Patient Marketing Group’s CEO, says that several technologies can help health plans evaluate compliance. Awac, a company in Augusta, Ga., for example, has software designed to do just that, says Rick Richards, MD, president and CEO.
Using claims data, the company’s software measures compliance by evaluating refill rates. The data are then evaluated relative to medical histories, and if anomalies occur, Awac nurses contact patients directly. “We enhance clinical competence,” says Richards. “That’s the purpose and value of determining compliance.”
“Adherence for specialty drugs is critical to quality care, maybe more so than anywhere in medicine,” says WellPoint’s Sweet.
Adherence to oral medications can be more of a problem than to injected drugs, says Kim Bergstrom, PharmD, chief clinical officer at McKesson Specialty Pharmacy Services.
Because multiple sclerosis patients frequently suffer from depression, which can result in nonadherence, Aetna Pharmacy Management may refer them to behavioral providers.
