A Study to Assess the Feasibility of Introducing Early Palliative Care in Ambulatory Patients with Advanced Lung Cancer

Defining "early palliative care" for adults diagnosed with a life-limiting illness: a scoping review

BACKGROUND

Palliative care is for people suffering from life-limiting illnesses that focuses on providing relief from symptoms and stress of illness. Previous studies have demonstrated that specialist palliative care consultation delivered earlier in the disease process can enhance patients' quality of life, reduce their symptom burden, reduce use of hospital-based acute care services and extend their survival. However, various definitions exist for the term early palliative care (EPC).

OBJECTIVE

To investigate how EPC has been defined in the literature for adults with life- limiting illnesses.

METHODS

This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) extension for Scoping Reviews guidelines and follows the Joanna Briggs Institution methodology for scoping reviews. The literature search was conducted using MEDLINE (Ovid), CINAHL (EBSCO), Embase (Ovid), PsycINFO (Ovid), Web of Science Core Collection, Ovid Cochrane Library, and ProQuest (Health and Medicine and Sociology Collections). All articles retrieved were screened by three independent reviewers.

RESULTS

153 articles met the inclusion criteria between 2008 and 2024. Five categories of definitions for EPC were created to organize definitions: (1) time-based (e.g. time from advanced cancer diagnosis to EPC initiation); (2) prognosis-based (e.g. prognosis or the 'surprise question'); (3) location-based (e.g. access point within the healthcare system such as outpatient setting); (4) treatment-based (e.g. physician's judgement or prior to specific therapies); and (5) symptom-based (e.g. using symptom intensity questionnaires). Many studies included patients with cancer (n = 103), with the most common definition category being time-based (n = 53). Amongst studies focusing on multiple or non-cancer diagnoses (n = 50), the most common definition category was symptom-based (n = 16).

CONCLUSION

Our findings provide a useful reference point for those seeking to understand the scope and breadth of existing EPC definitions in cancer and non-cancer illnesses and contemplate their application within clinical practice.

Palliative and end-of-life care initiatives for people dying from cancer in India: a narrative review

India is facing a growing burden of cancer, resulting in high cancer-associated mortality. However, the rise in cancer incidence is disproportionately high compared to access and provision of palliative care. This review aims to identify gaps in Indian cancer palliative care and recognises initiatives instituted to mitigate them. The narrative review was conducted using the four-step method described by Demiris et al., synthesising both empirical and non-empirical literature. A lack of capacity to provide palliative care was identified as a significant barrier. Initiatives such as setting up palliative care services in cancer treatment centres, improving community palliative care access, structured palliative care training to develop specialists, improving opioid availability and creating policies have been helpful. A significant proportion of people in India experience health-related suffering, and developing a tool to identify this suffering proactively would be beneficial. Several cancer centres are testing integrated cancer palliative care models in various cancer subsites. However, these are preliminary works and are yet to be established. People in India face distress due to high health-related costs, and initiatives like hospices and home-based palliative care services with no cost to patients and families provide significant relief. Caregivers experience a considerable burden while caring for their loved ones with life-limiting illnesses, and they are supported through respite palliative care services offered in some parts of India.

Feasibility of a Two-Step Palliative Screening Utilizing Existing Emergency Department Resources

BACKGROUND

Although the Emergency Department (ED) offers a unique setting to provide early palliative care, staffing limitations curtail hospitals from establishing ED-palliative partnerships.

MEASURES

Feasibility of a two-step ED-palliative screening protocol was defined by two criteria: a ≥ 50% increase in palliative consults originating from the ED and a ≥ 50% consultation completion rate for patients who screened positive for unmet palliative needs.

INTERVENTION

A clinical decision support tool identified patients with treatment/code status limitations and prompted a care coordination referral. Care coordinators screened patients for unmet palliative needs using a content-validated screening tool and consulted palliative care for positive screens.

OUTCOME

Palliative care consultations originating from the ED increased by 110% from 32 to 67 consultations, and 57% (40/70) of patients who screened positive for unmet palliative needs received a consultation.

CONCLUSIONS/LESSONS LEARNED

Our project demonstrated feasibility of a two-step ED-palliative protocol by increasing palliative care consultation without necessitating additional staff.

Integrating Palliative Care into Oncology Care Worldwide: The Right Care in the Right Place at the Right Time

OPINION STATEMENT

While the benefits of early palliative care are indisputable, most of the current evidence has emerged from resource-rich settings in urban areas of high-income countries, with an emphasis on solid tumors in outpatient settings; this model of palliative care integration is not currently scalable internationally. A shortage of specialist palliative care clinicians means that in order to meet the needs of all patients who require support at any point along their advanced cancer trajectory, palliative care must also be provided by family physicians and oncology clinicians who require training and mentorship. Models of care that facilitate the timely provision of seamless palliative care across all settings (inpatient, outpatient, and home-based care), with clear communication between clinicians, are crucial to the provision of patient-centred palliative care. The unique needs of patients with hematological malignancies must be further explored and existing models of palliative care provision modified to meet these needs. Finally, care must be provided in an equitable and culturally sensitive manner, recognizing the challenges associated with the delivery of high-quality palliative care to both patients in high-income countries who live in rural areas, as well as to those in low- and middle-income countries. A one-size-fits-all model will not suffice, and there is an urgent need to develop innovative context-specific models of palliative care integration worldwide, in order to provide the right care, in the right place, and at the right time.

Models of Integration of Specialized Palliative Care with Oncology

OPINION STATEMENT

Evidence from randomized controlled trials and meta-analyses has shown that early integration of specialized palliative care improves symptoms and quality of life for patients with advanced cancer. There are various models of early integration, which may be classified based on setting of care and method of palliative care referral. Most successful randomized controlled trials of early palliative care have used a model of specialized teams providing in-person palliative care in free-standing or embedded outpatient clinics. During the COVID-19 pandemic, telehealth has become a prominent model for palliative care delivery. This model of care has been well received by patients and palliative care providers, although evidence to date is limited. Despite evidence from trials that routine early integration of palliative care into oncology care improves patient outcomes, referral to palliative care still occurs mostly according to the judgment of individual oncologists. This hinders equitable access to palliative care and to its known benefits for patients and their caregivers. Automated referral based on triggering criteria is being actively explored as an alternative. In particular, routine technology-assisted symptom screening, combined with targeted needs-based automatic referral to outpatient palliative care, may improve integration and ultimately increase quality of life.

Implementation of an Early Palliative Care Referral Program in Lung Cancer: A Quality Improvement Project at the Tata Memorial Hospital, Mumbai, India

OBJECTIVES

Access to early palliative care (EPC) for all patients with metastatic lung cancer is yet to be achieved in spite of recommendations. This quality improvement (QI) project was initialized to improve the rates of such referrals from the thoracic oncology clinic for all new outpatients in a premier cancer center in India.

MATERIALS AND METHODS

Change in the proportion of patients receiving referrals for EPC during and after intervention (April-May 2018), compared to baseline (January-March 2018) were explored. Interventions included understanding of the process flow, identification of key drivers, and root cause analysis which identified the gaps as lack of documentation for EPC. Teaching and encouraging staff at the clinic to incorporate referrals into all initial visits for patients with metastatic lung cancer were incorporated.

RESULTS

The bundle of QI interventions increased referrals from an average of 50% to 75%, mean difference = 12.64 (standard deviation = 10.13) (95% confidence interval = 22.01-3.29), P = 0.016 (two-tailed) on paired sample test.

CONCLUSION

Improved referral rates for EPC in a multidisciplinary cancer clinic is possible with a QI project. This project also identifies the importance of data documentation and patient information processes that can be targeted for improvement.

Evolution and Conceptual Foundations of Nonhospice Palliative Care

The term nonhospice palliative care was developed to describe and differentiate palliative care that is delivered prior to the end of life. The purpose of this article is to better define and clarify this concept using Rodgers’s evolutionary concept analysis method. Attributes of nonhospice palliative care include (a) patient- and family-centered care, (b) holistic care, (c) interdisciplinary team, (d) early intervention, (e) quality of life-enhancing, (f) advanced care planning, (g) any age of the patient, (h) at any stage in illness, (i) care coordination, (j) concurrent curative treatment options, and (k) provided by primary and specialist providers. Nonhospice palliative care antecedents are serious illness, education, and access to services; consequences include benefits for the patient, family, provider, and health care system. Offering a clearly defined concept may allow for changes in health care to improve access to these services.

Early palliative care for adults with advanced cancer

BACKGROUND

Incurable cancer, which often constitutes an enormous challenge for patients, their families, and medical professionals, profoundly affects the patient's physical and psychosocial well-being. In standard cancer care, palliative measures generally are initiated when it is evident that disease-modifying treatments have been unsuccessful, no treatments can be offered, or death is anticipated. In contrast, early palliative care is initiated much earlier in the disease trajectory and closer to the diagnosis of incurable cancer.

OBJECTIVES

To compare effects of early palliative care interventions versus treatment as usual/standard cancer care on health-related quality of life, depression, symptom intensity, and survival among adults with a diagnosis of advanced cancer.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, OpenGrey (a database for grey literature), and three clinical trial registers to October 2016. We checked reference lists, searched citations, and contacted study authors to identify additional studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) and cluster-randomised controlled trials (cRCTs) on professional palliative care services that provided or co-ordinated comprehensive care for adults at early advanced stages of cancer.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures as expected by Cochrane. We assessed risk of bias, extracted data, and collected information on adverse events. For quantitative synthesis, we combined respective results on our primary outcomes of health-related quality of life, survival (death hazard ratio), depression, and symptom intensity across studies in meta-analyses using an inverse variance random-effects model. We expressed pooled effects as standardised mean differences (SMDs, or Hedges' adjusted g). We assessed certainty of evidence at the outcome level using GRADE (Grading of Recommendations Assessment, Development, and Evaluation) and created a 'Summary of findings' table.

MAIN RESULTS

We included seven randomised and cluster-randomised controlled trials that together recruited 1614 participants. Four studies evaluated interventions delivered by specialised palliative care teams, and the remaining studies assessed models of co-ordinated care. Overall, risk of bias at the study level was mostly low, apart from possible selection bias in three studies and attrition bias in one study, along with insufficient information on blinding of participants and outcome assessment in six studies.Compared with usual/standard cancer care alone, early palliative care significantly improved health-related quality of life at a small effect size (SMD 0.27, 95% confidence interval (CI) 0.15 to 0.38; participants analysed at post treatment = 1028; evidence of low certainty). As re-expressed in natural units (absolute change in Functional Assessment of Cancer Therapy-General (FACT-G) score), health-related quality of life scores increased on average by 4.59 (95% CI 2.55 to 6.46) points more among participants given early palliative care than among control participants. Data on survival, available from four studies enrolling a total of 800 participants, did not indicate differences in efficacy (death hazard ratio 0.85, 95% CI 0.56 to 1.28; evidence of very low certainty). Levels of depressive symptoms among those receiving early palliative care did not differ significantly from levels among those receiving usual/standard cancer care (five studies; SMD -0.11, 95% CI -0.26 to 0.03; participants analysed at post treatment = 762; evidence of very low certainty). Results from seven studies that analysed 1054 participants post treatment suggest a small effect for significantly lower symptom intensity in early palliative care compared with the control condition (SMD -0.23, 95% CI -0.35 to -0.10; evidence of low certainty). The type of model used to provide early palliative care did not affect study results. One RCT reported potential adverse events of early palliative care, such as a higher percentage of participants with severe scores for pain and poor appetite; the remaining six studies did not report adverse events in study publications. For these six studies, principal investigators stated upon request that they had not observed any adverse events.

AUTHORS' CONCLUSIONS

This systematic review of a small number of trials indicates that early palliative care interventions may have more beneficial effects on quality of life and symptom intensity among patients with advanced cancer than among those given usual/standard cancer care alone. Although we found only small effect sizes, these may be clinically relevant at an advanced disease stage with limited prognosis, at which time further decline in quality of life is very common. At this point, effects on mortality and depression are uncertain. We have to interpret current results with caution owing to very low to low certainty of current evidence and between-study differences regarding participant populations, interventions, and methods. Additional research now under way will present a clearer picture of the effect and specific indication of early palliative care. Upcoming results from several ongoing studies (N = 20) and studies awaiting assessment (N = 10) may increase the certainty of study results and may lead to improved decision making. In perspective, early palliative care is a newly emerging field, and well-conducted studies are needed to explicitly describe the components of early palliative care and control treatments, after blinding of participants and outcome assessors, and to report on possible adverse events.
