One Step Forward, Two Steps Back: Trends in Aggressive Inpatient Care at the End of Life for Patients With Stage IV Lung Cancer

ACO Spending and Utilization Among Medicare Patients at the End of Life: an Observational Study

BACKGROUND

End-of-life (EOL) costs constitute a substantial portion of healthcare spending in the USA and have been increasing. ACOs may offer an opportunity to improve quality and curtail EOL spending.

OBJECTIVE

To examine whether practices that became ACOs altered spending and utilization at the EOL.

DESIGN

Retrospective analysis of Medicare claims.

PATIENTS

We assigned patients who died in 2012 and 2015 to an ACO or non-ACO practice. Practices that converted to ACOs in 2013 or 2014 were matched to non-ACOs in the same region. A total of 23,643 ACO patients were matched to 23,643 non-ACO patients.

MAIN MEASURES

Using a difference-in-differences model, we examined changes in EOL spending and care utilization after ACO implementation.

KEY RESULTS

The introduction of ACOs did not significantly impact overall spending for patients in the last 6 months of life (difference-in-difference (DID) = $192, 95%CI -$841 to $1125, P = 0.72). Changes in spending did not differ between ACO and non-ACO patients across spending categories (inpatient, outpatient, physician services, skilled nursing, home health, hospice). No differences were seen between ACO and non-ACO patients in rates of ED visits, inpatient admissions, ICU admission, mean healthy days at home, and mean hospice days at 180 and 30 days prior to death. However, non-ACO patients had a significantly greater increase in hospice utilization compared to ACO patients at 180 days (DID P-value = 0.02) and 30 days (DID P-value = 0.01) prior to death.

CONCLUSIONS

With the exception of hospice care utilization, spending and utilization were not different between ACOs and non-ACO patients at the EOL. Longer follow-up may be necessary to evaluate the impact of ACOs on EOL spending and care.

Critical illness in patients with metastatic cancer: a population-based cohort study of epidemiology and outcomes

The appropriateness of intensive care unit (ICU) admission of patients with metastatic cancer remains debated. We aimed to examine the short-term outcomes and their temporal pattern in critically ill patients with metastatic disease. We used state-wide data to identify hospitalizations aged ≥18 years with metastatic cancer admitted to ICU in Texas during 2010-2014. Multivariable logistic regression modeling was used to examine the factors associated with short-term mortality and its temporal trends among all ICU admissions and those undergoing mechanical ventilation. Among 136,644 ICU admissions with metastatic cancer, 50.8% were aged ≥65 years, with one or more organ failures present in 53.3% and mechanical ventilation was used in 11.1%. The crude short-term mortality among all ICU admissions and those mechanically ventilated was 28.1% and 62.0%, respectively. Discharge to home occurred in 57.1% of all ICU admissions. On adjusted analyses, short-term mortality increased with rising number of organ failures (adjusted OR (aOR) 1.399, 95% CI 1.374 to 1.425), while being lower with chemotherapy (aOR 0.467, 95% CI 0.432 to 0.506) and radiation therapy (aOR 0.832, 95% CI 0.749 to 0.924), and decreased over time (aOR 0.934 per year, 95% CI 0.924 to 0.945). Predictors of short-term mortality were largely similar among those undergoing mechanical ventilation. Most ICU admissions with metastatic cancer survived hospitalization, although short-term mortality was very high among those undergoing mechanical ventilation. Short-term mortality decreased over time and was lower among those receiving chemotherapy and radiation therapy. These findings support consideration of critical care in patients with metastatic cancer, but underscore the need to address patient-centered goals of care ahead of ICU admission.

Association between strong patient-oncologist agreement regarding goals of care and aggressive care at end-of-life for patients with advanced cancer

INTRODUCTION

The ability of oncologists to understand patients' goals of care is recognized as a key component of quality care. The purpose of this study is to examine the influence of patient-oncologist agreement regarding goals of care upon aggressive care at end of life (EOL) for patients with advanced cancer.

METHODS

Patients with advanced cancer and their oncologists were interviewed at study enrollment and every 3 months thereafter until patient death or end of the study period (15 months). A 100-point visual analogue scale was used to represent goals of care, with quality of life (scored as 0) and survival (scored as 100) as anchors. Strong goal of care agreement for survival was defined as oncologist and patient dyadic goal of care scores that fell between 70 and 100 (100 = highest goal for survival) and for comfort, dyadic goal of care values that fell between 0 and 30 (0 = high goal for comfort).

RESULTS

Two hundred and six patients and eleven oncologists provided data. At the last interview prior to death, 23.3% of dyads had strong goal of care agreement for either survival (8.3%) or comfort (15%) and 76.7% had no strong agreement. There was a significant association between aggressive care use and categories of dyadic agreement regarding goals of care (p = 0.024, Cramer's V = 0.15).

CONCLUSIONS

A large percentage of oncologists did not understand their patients' EOL goals of care. While aggressive care aligned with categories of dyadic agreement for goals of care, high rates of aggressive care were reported.

The role of palliative care in the management of patients with lung cancer

Palliative care (PC) is the care of patients and their families with serious illness and is rapidly becoming an important part of the care of cancer patients. Patients with advanced lung cancer are a highly symptomatic population of patients and clearly experience benefits in quality of life and potentially benefits in overall survival when PC is incorporated early on after diagnosis. However, referrals to PC are still reliant on clinical judgment of patient prognosis and symptom burden. Moving forward, improving the integration of PC and lung cancer care will require more efficient real-time screening of patient symptoms, which may be accomplished through the use of patient-reported outcomes.

Strengths and limitations of large databases in lung cancer radiation oncology research

There has been a substantial rise in the utilization of large databases in radiation oncology research. The advantages of these datasets include a large sample size and inclusion of a diverse population of patients in a real-world setting. Such observational studies hold promise in enhancing our understanding of questions for which evidence is conflicting or absent in lung cancer radiotherapy. However, it is critical that investigators understand the strengths and limitations of large databases in order to avoid the common pitfalls that beset observational analyses. This review begins by outlining the data variables available in major registries that are used most often in observational analyses. This is followed by a discussion of the type of radiotherapy-related questions that can be addressed using such datasets, accompanied by examples from the lung cancer literature. Finally, we describe some limitations of observational research and techniques to mitigate bias and confounding. We hope that clinicians and researchers find this review helpful for designing new research studies and interpreting published analyses in the literature.

Lung cancer and end-of-life care: a systematic review and thematic synthesis of aggressive inpatient care

OBJECTIVES

Despite recent advances in thoracic oncology, most patients with metastatic lung cancer die within months of diagnosis. Aggressiveness of their end-of-life (EOL) care has been the subject of numerous studies. This study was undertaken to evaluate the literature on aggressive inpatient EOL care for lung cancer and analyse the evolution of its aggressiveness over time.

METHODS

A systematic international literature search restricted to English-language publications used terms associated with aggressiveness of care, EOL and their synonyms. Two independent researchers screened for eligibility and extracted all data and another a random 10% sample of the abstracts. Electronic Medline and Embase databases were searched (2000-20 September 2018). EOL-care aggressiveness was defined as follows: 1) chemotherapy administered during the last 14 days of life (DOL) or new chemotherapy regimen during the last 30 DOL; 2) >2 emergency department visits; 3) >1 hospitalisation during the last 30 DOL; 4) ICU admission during the last 30 DOL and 5) palliative care started <3 days before death.

RESULTS

Among the 150 articles identified, 42 were retained for review: 1 clinical trial, 3 observational cohorts, 21 retrospective analyses and 17 administrative data-based studies. The percentage of patients subjected to aggressive therapy seems to have increased over time. Early management by palliative care teams seems to limit aggressive care.

CONCLUSIONS

Our analysis indicated very frequent aggressive EOL care for patients with lung cancer, regardless of the definition used. The extent of that aggressiveness and its impact on healthcare costs warrant further studies.

End-of-life care in individuals with respiratory diseases: a population study comparing the dying experience between those with chronic obstructive pulmonary disease and lung cancer

Purpose

Among individuals with COPD and/or lung cancer, to describe end-of-life health service utilization, costs, and place of death; to identify predictors of home palliative care use, and to assess benefits associated with palliative care use.

Patients and methods

We conducted a retrospective population-based study using provincial linked health administrative data (Ontario, Canada) between 2010 and 2015. We examined health care use in the last 90 days of life in adults 35 years and older with physician-diagnosed COPD and/or lung cancer identified using a validated algorithm and the Ontario Cancer Registry, respectively. Four mutually exclusive groups were considered: (i) COPD only, (ii) lung cancer only, (iii) COPD and lung cancer, and (iv) neither COPD nor lung cancer. Multivariable generalized linear models were employed.

Results

Of 445,488 eligible deaths, 34% had COPD only, 4% had lung cancer only, 5% had both and 57% had neither. Individuals with COPD only received less palliative care (20% vs 57%) than those with lung cancer only. After adjustment, people with lung cancer only were far more likely to receive palliative care (OR=4.22, 4.08–4.37) compared to those with neither diagnosis, while individuals with COPD only were less likely to receive palliative care (OR=0.82, 0.81–0.84). Home palliative care use was associated with reduced death and fewer days in acute care, and less cost, regardless of the diagnosis.

Conclusion

Although individuals with lung cancer were much more likely to receive palliative care than those with COPD, both populations were underserviced. Results suggest greater involvement of palliative care may improve the dying experience of these populations and reduce costs.

Resource utilisation and description of patients perceived as receiving inappropriate critical care

OBJECTIVE

Medical interventions that do not offer the patient meaningful benefit due to inconsistency with prognoses are often considered "inappropriate" by clinicians. We described the clinical details and resource utilisation of patients who were assessed as receiving inappropriate treatment.

DESIGN

Chart abstraction was performed on 123 patients who were assessed by their critical care physician as having received inappropriate treatment to document clinical characteristics, diagnostic testing, life-sustaining treatments and nursing assessments of daily pain and level of consciousness.

RESULTS

The mean age was 67 and on admission, 41% had cancer and 25% had advanced pulmonary disease. At least one of the following three conditions was noted in 57% of the patients: severe neurological injury, overwhelming sepsis or irreversible respiratory failure. Patients were less likely to be alert (OR 0.39, CI 0.16-0.91, p = 0.03) on days they were assessed as receiving inappropriate critical care. After they were assessed as receiving inappropriate critical care, they received 172 imaging studies, 151 procedures, 522 days of mechanical ventilation (excludes one patient who received 1020 days of mechanical ventilation), 254 days of vasopressors, 226 days of hemodialysis and 10 attempts at cardiopulmonary resuscitation.

CONCLUSIONS

Patients assessed as receiving inappropriate critical care receive resource-intensive medical care, largely while non-alert.
