When Life Imitates Art: Surrogate Decision Making at the End of Life

Escalation and Withdrawal of Treatment for Patients on Extracorporeal Membrane Oxygenation: A Qualitative Study

OBJECTIVE

The aim of this study was to describe decisions about the escalation and withdrawal of treatment for patients on extracorporeal membrane oxygenation (ECMO).

SUMMARY BACKGROUND DATA

Interventions premised on facilitating patient autonomy have proven problematic in guiding treatment decisions in intensive care units (ICUs). Calls have thus been made to better understand how decisions are made in critical care. ECMO is an important form of cardiac and respiratory support, but care on ECMO is characterized by prognostic uncertainty, varying time course, and high resource use. It remains unclear how decisions about treatment escalation and withdrawal should be made for patients on ECMO and what role families should play in these decisions.

METHODS

We performed a focused ethnography in 2 cardiothoracic ICUs in 2 US academic hospitals. We conducted 380 hours of observation, 34 weekly interviews with families of 20 ECMO patients, and 13 interviews with unit clinicians from January to September 2018. Qualitative analysis used an iterative coding process.

RESULTS

Following ECMO initiation, treatment was escalated as complications mounted until the patient either could be decannulated or interventional options were exhausted. Families were well-informed about treatment and prognosis but played minimal roles in shaping the trajectory of care.

CONCLUSIONS

Discussion between clinicians and families about prognosis and goals was frequent but did not occasion decision-making moments. This study helps explain why communication interventions intended to maintain patient autonomy through facilitating surrogate participation in decisions have had limited impact. A more comprehensive understanding of upstream factors that predispose courses of critical care is needed.

Accuracy in Surrogate End-of-Life Medical Decision-Making: A Critical Review

BACKGROUND

Increasing age is accompanied by a greater need for medical decisions, due in part to age-related increases in chronic disease and disability. In later life, medical decisions about end-of-life care in particular are likely. However, a significant percentage of these decisions are made by surrogate decision-makers. "Surrogates" are most often instructed to use the substituted judgment standard and make decisions that patients would choose if they were able. Whether surrogates make decisions that adequately match patients' preferences is a concern. Surrogates are generally poor predictors of patient preferences (Shalowitz et al., 2006). However, no critical review of this literature has yet been published.

METHOD

A critical review was conducted to summarise and provide a methodological critique of 25 studies.

RESULTS

These studies generally concur that patient-surrogate agreement on medical decisions is poor. However, this conclusion is qualified by inconsistencies in methodological quality and the potentially limited generalisability of these findings.

CONCLUSIONS

Clinical research incorporating standardised hypothetical decision-making protocols, as well as triangulated data collection methods, would bolster confidence in future findings. Investigations prioritising the surrogate decision-making process, rather than solely the decisional outcome, could better identify ways to improve the decision-making process for incapacitated patients.

What would people think? Perceived social norms, willingness to serve as a surrogate, and end-of-life treatment decisions

BACKGROUND

Population aging has increased the prevalence of surrogate decision making in healthcare settings. However, little is known about factors contributing to the decision to become a surrogate and the surrogate medical decision-making process in general. We investigated how intrapersonal and social-contextual factors predicted two components of the surrogate decision-making process: individuals' willingness to serve as a surrogate and their tendency to select various end-of-life treatments, including mechanical ventilation and palliative care options.

METHOD

An online sample (N = 172) of adults made hypothetical surrogate decisions about end-of-life treatments on behalf of an imagined person of their choice, such as a parent or spouse. Using self-report measures, we investigated key correlates of willingness to serve as surrogate (e.g., decision-making confidence, willingness to collaborate with healthcare providers) and choice of end-of-life treatments.

RESULTS

Viewing service as a surrogate as a more typical practice in healthcare was associated with greater willingness to serve. Greater decision-making confidence, greater willingness to collaborate with patients' physicians, and viewing intensive, life-sustaining end-of-life treatments (e.g., mechanical ventilation) as more widely accepted were associated with choosing more intensive end-of-life treatments.

SIGNIFICANCE OF RESULTS

The current study's consideration of both intrapersonal and social-contextual factors advances knowledge of two key aspects of surrogate decision making - the initial decision to serve as surrogate, and the surrogate's selection of various end-of-life treatment interventions. Providers can use information about the role of these factors to engage with surrogates in a manner that better facilitates their decision making. For instance, providers can be sensitive to potential cultural differences in surrogate decision-making tendencies or employing decision aids that bolster surrogates' confidence in their decisions.

Discrepancies in End-of-life Decisions Between Elderly Patients and Their Named Surrogates

Introduction: This study aims to determine the attitudes of Asian elderly patients towards invasive life support measures, the degree of patient-surrogate concordance in end-of-life decision making, the extent to which patients desire autonomy over end-of-life medical decisions, the reasons behind patients’ and surrogates’ decisions, and the main factors influencing patients’ and surrogates’ decision-making processes. We hypothesize that there is significant patient-surrogate discordance in end-of-life decision making in our community. Materials and Methods: The patient and surrogate were presented with a hypothetical scenario in which the patient experienced gradual functional decline in the community before being admitted for life-threatening pneumonia. It was explained that the outcome was likely to be poor even with intensive care and each patient-surrogate pair was subsequently interviewed separately on their opinions of extraordinary life support using a standardised questionnaire. Both parties were blinded to each other’s replies. Results: In total, 30 patients and their surrogate decision-makers were interviewed. Twenty-eight (93.3%) patients and 20 (66.7%) surrogates rejected intensive care. Patient-surrogate concurrence was found in 20 pairs (66.7%). Twenty-four (80.0%) patients desired autonomy over their decision. The patients’ and surrogates’ top reasons for rejecting intensive treatment were treatment-related discomfort, poor prognosis and financial cost. Surrogates’ top reasons for selecting intensive treatment were the hope of recovery, the need to complete final tasks and the sanctity of life. Conclusion: The majority of patients desire autonomy over critical care issues. Relying on the surrogates’ decisions to initiate treatment may result in treatment against patients’ wishes in up to one-third of critically ill elderly patients.
