ABSTRACT: This article addresses the practical application of palliative care (PC) in the outpatient oncology setting. While information on this topic is scarce, data published by a few outpatient practices provide the basis for potential models of integrated care. In general, the perceived impact of integrating PC into standard oncology practice is positive for patients, providers, oncology practices, and the healthcare system as a whole. As the benefits of integrating PC into oncology practice continue to be realized, more data will become available.
Palliative care (PC) within oncology is a topic of much interest because of the accumulating evidence that it may lead to better symptom management, improved patient and caregiver quality of life (QOL), better survival outcomes, and reduced cost to society. In this article, we will use the definition of palliative care most commonly applied in clinical practice today (see sidebar).
We will describe the current published evidence regarding optimal ways to integrate PC into practical oncology care, given that so much of cancer-care costs are controlled or influenced directly by oncologists. We will state up-front that there is minimal published evidence of best-practice approaches to PC cancer patients in the outpatient setting. This is not surprising: less than 1% of the National Cancer Institute research budget funds PC studies, and the American Board of Medical Specialties established the new subspecialty certificate in hospice and palliative medicine just 5 years ago, so training programs in PC are just beginning. PC in US hospitals has expanded dramatically in the past decade, however; the number of hospitals with a PC team grew from 658 (24.5%) to 1,568 (63.0%)—a steady 138.3% increase from 2000-2009. Given the growth of inpatient services in PC, we anticipate that outpatient services will develop rapidly.
What Is the Evidence for Concurrent Care in Practice?
Only a few published studies describe concurrent PC and oncology care, as shown in Table 1. This section of our article describes models for integrated outpatient PC and oncology care, from the literature and at our own institution.
The palliative care program at Princess Margaret Hospital, Toronto
The Princess Margaret Hospital (PMH) palliative care program in Toronto, Canada, began in 2001, starting with an inpatient PC consultation service which later expanded into an acute care inpatient unit, as well as daily PC clinics and a separate cancer pain clinic. Each clinic is staffed by a PC physician and a registered nurse case manager, who evaluate patients and make referrals to psychiatrists, psychologists, social workers, and dieticians, as needed. Follow-up occurs in the PC clinic and by telephone. For patient convenience, the clinic makes an effort to schedule PC follow-up visits in conjunction with other appointments, such as chemotherapy, radiation, transfusions, or other tests. This PC program offers comprehensive clinical and support services, which might not be feasible in institutions with limited clinic space and time.
As mentioned, PMH has a weekly cancer pain clinic, which represents a more integrated model of PC and oncology. It is staffed by an oncologist, a PC physician, and an advanced practice nurse (APN). The clinic's services are limited to patients with cancer and, as described by Zimmerman et al, typically those with a relatively long prognosis (months to years). Patients are followed in the clinic once every 1 to 2 months, but the majority of medication adjustments are handled by the APN via telephone follow-up. With clinics offered only weekly and the majority of follow-up handled by phone, this particular model is more feasible for institutions with limited clinic resources.
The PMH system also has a method to address urgent outpatient consultations. These patients are seen by a member of the PC team either at the referring clinic itself or in the PC clinic, depending on availability of space and patient convenience. After the urgent consultation is complete, the patient is scheduled into the clinic of the PC physician who performed the urgent consultation. Additionally, clinic patients have access to a 24-hour on-call service staffed by PC physicians. This unlimited physician availability may be difficult to provide in many settings.
Another model for a partially integrated outpatient PC service is at Cleveland Clinic, as described by Walsh. Cleveland Clinic began their program in 1987, based on the program at Royal Victoria Hospital in Montreal, Quebec, Canada. After Cleveland Clinic began their inpatient PC consultation service, the need for outpatient follow-up of these patients was met by starting a PC outpatient clinic. The PC clinic patients are seen in the oncology clinic during 5 half-days each week. This system uses a nurse-manager model in which each patient is followed by a particular nurse manager as an inpatient, in the clinic, or at home. The nurse manager serves as the patient's main contact and helps to coordinate services for the patient. Besides offering patients continuity of care, the service provides a nurse-manager directed 24-hour on-call service.
The US Oncology national Capital Region Hospice and Palliative Care model
One business-centered model of integrating PC into the outpatient oncology setting was recently demonstrated by Cameron Muir and colleagues at a US Oncology site in Northern Virginia. An independent PC consult practice was embedded into the private oncology clinic and received referrals from the eight oncologists within the group. The consult practice consisted of a PC attending and fellow who saw patients during 1 half-day period per week. Clinic space was rented by the PC team at fair-market value. To avoid billing for the same diagnoses, the oncologists coded for cancer-related diagnoses (eg, pancreatic cancer) and the PC physicians coded for symptom diagnoses (eg, abdominal pain). By the end of the 2-year study, referrals from the oncologists increased by 87%, patient symptom burden decreased by more than 20%, and the oncologists' overall satisfaction with the PC consult practice was rated at 9 out of 10.
From a business perspective, Muir et al estimated that each PC referral saved approximately 170 minutes of the referring oncologist's time. Presumably, the time gained could be used by oncologists to see additional patients and focus on the oncologic aspects of their patients' care. To compensate for the clinic space and time used by the PC consultants, as well as their salaries, Muir and colleagues estimated that the PC consultants needed to evaluate at least two new patients and provide four to six follow-up consults per clinic half-day. In their current practice model, the physician and an APN have 4 new patient consultations and follow-up visits with 10 to 14 patients in a half-day session.
Muir et al concluded that the embedded PC consult practice was feasible from both a clinical and business perspective. The PC consultants improved patient symptom burden and garnered high approval by the oncologists in the practice. They drastically decreased the amount of time that oncologists spent in managing symptoms and discussing care goals, allowing the opportunity for increased productivity and a higher quality of cancer care. According to the authors, having the palliative practice embedded into the oncology practice was advantageous because the shared physical space and close contact of physicians facilitated integration of the two practices.
Although the study demonstrated successful integration of PC and oncology in the outpatient setting, it did have limitations. The PC consultation service lacked an interdisciplinary team to optimize the PC delivered, which raises questions about the feasibility of integrating an entire interdisciplinary team into an outpatient oncology practice. By focusing on the business aspects of integrating the two practices, the study provided limited data about the impact of the intervention on patients in the oncology practice. The authors later noted that the number of referrals could have been facilitated by identifying certain diagnoses or clinical situations that would trigger PC consults, such as malignant pleural effusion, intractable pain, or an Eastern Cooperative Oncology Group (ECOG) performance status of 3 or higher. In addition, the authors are left with the question of how to make their integrated model scaleable and reproducible in other settings.
Virginia Commonwealth University–Massey Cancer Center palliative care services
At Virginia Commonwealth University (VCU), there is a similar PC pain clinic in addition to the inpatient palliative acute care unit and inpatient consultative services. This clinic utilizes space in the oncology clinic for 1 half-day per week and is staffed by a PC attending and fellow. Patients are referred for assistance with cancer pain management and are ideally managed long-term by their primary oncologists once a stable regimen has been reached. Patients are generally referred from their outpatient oncologist's clinic, but many patients have been seen as inpatient palliative consults. Nursing support is provided by the oncology department for the clinic as well as for triage calls. Social work support also is included in the oncology department services. To create a more interdisciplinary team, the most recent addition to VCU's services has been to provide psychology resources during clinic time. Our psychologist is part of the inpatient oncology and PC teams, is in-house during the day, and can be paged to the clinic if needed. A similar system is in place for chaplaincy services. We (authors ERA, DF) have noticed that the integration with oncology via the social worker and nurse from their department provides continuity for these patients with often-complicated needs. However, we believe more active involvement of the palliative physicians with the patient's oncologist in terms of face-to-face discussion during clinic time would further enhance continuity of care and facilitate development of more comprehensive care plans for each patient.
To improve the interface between palliative and oncology providers in the outpatient setting, the palliative fellows at VCU have begun to attend the oncology fellows' pre-clinic conference each week. During the discussion about scheduled oncology clinic patients, the PC fellow identifies palliative concerns and suggests ways to improve how these concerns are addressed. As a consultant, the PC fellow then sees patients during their oncology clinic visit, to address any PC issues. The oncology fellow either stays in the room during the consultation or sees other patients during that time and then discusses the care plan with the palliative fellow. In the 5 months of this collaboration, the shared time and space of the oncology clinic with the palliative consultant has not negatively impacted clinic flow. In addition, the palliative and oncology fellows believe this integration of services has enhanced the quality of cancer care in the clinic. Thus, we have found that incorporating PC into the oncology fellows' clinic is both feasible for the clinic and convenient for the patient. This integration could serve as a model for other institutions that have established palliative and oncology services.
The financial sustainability of this program is now under evaluation. The chaplain and the psychologist do not bill for their visits, and their salary is contributed by the Massey Cancer Center. An oncology social worker is available at VCU's safety net institution, to help patients meet the many emotional and practical challenges of cancer.
