Cardiopulmonary resuscitation (CPR) is an invasive medical treatment. It was first used to treat patients whose hearts were too good to die. While it can be a life-saving intervention in that context, CPR is not an effective treatment for people who are approaching the end of their natural lives. Do-not-resuscitate (DNR) orders or code decisions provide a mechanism through which a preemptive decision can be made—usually with the patient—to withhold CPR in the event of a cardiac arrest. Broadly speaking, DNR decisions are appropriate when there is little or no chance that resuscitation will be successful, when the balance of burdens outweighs the benefits, or when a patient advises that they do not want to be resuscitated.1 A key requirement of effective patient-centered health care is the involvement of the patient in decision making. It is therefore timely that Becker et al2 report findings from a systematic review and meta-analysis of communication interventions to aid resuscitation decisions and explore their association with patient decisions and knowledge about DNR orders. The review by Becker et al2 draws on evidence from 15 randomized clinical trials involving 2405 adult patients, mostly in a US setting. Most (11) trials included a video; others provided written material, structured discussions, or counseling. The meta-analysis of 11 randomized clinical trials by Becker et al2 found that communication interventions reduced patient preferences for CPR from 53.6% to 38.6% (risk ratio, 0.70; 95% CI, 0.63-0.78) and improved patients’ knowledge about CPR treatment. Subgroup analyses identified that video-assisted decision aids were most effective in achieving these outcomes. Interventions worked better among older patients, men, and those with lower literacy. Becker et al2 suggest that these interventions improve knowledge, thereby enabling patients to actively participate in the decision-making process.
Making decisions about CPR more patient centered is a worthy goal; for decades, these decisions were hidden or talked about in code,3 and as Becker et al2 reference, discussions are still often avoided or done badly. Part of clinicians’ reluctance to discuss CPR with patients may stem from a widely acknowledged problem with the interpretation of DNR documentation. In a 2016 review of DNR decisions across the United Kingdom,3 a key concern reported by clinicians was the perception that DNR decisions were being misinterpreted to mean do not provide any treatment. An accompanying systematic review of international studies4 found that DNR decisions were associated with fewer invasive medical treatments, reduced escalation to medical and intensive care staff in the event of deterioration, fewer nursing observations, and less robust basic care, including less pain relief and altered fluid intake.
Linking discussions about resuscitation with decisions about other aspects of emergency care and treatment helps to provide greater clarity about the goals of care, can aid communication among clinicians, and may reduce the harms identified from decisions that focus only on withholding resuscitation.5 In the UK health setting, the Resuscitation Council (UK) established the Recommended Summary Plan for Emergency Care and Treatment (ReSPECT).6 This facilitates personalized recommendations for clinical care in a future emergency (including resuscitation) in the situation that the patient is unable to make or express choices. It provides health care professionals with a summary of recommendations to help them make immediate decisions about that person’s care and treatment. Similar, patient-focused systems that encourage dialogue between patients and clinicians to formulate overall treatment plans have been growing across North America (eg, Physician Orders for Life Sustaining Treatment, Medical Orders for Scope of Treatment). A 2019 systematic review7 identified 34 unique interventions to guide advance care planning. Notably, only 1 of the interventions included a video, which was used alongside group sessions to discuss overall care plans. Having videos that focus only on CPR (which can appear brutal) might perpetuate the idea that CPR needs to be considered in isolation from other treatments or treatment goals. A video—which is inherently generic—might also detract from the need to individualize the conversation; ideally, discussions should enable the clinician and patient to achieve a shared understanding of what outcomes that particular patient values and what outcomes are clinically achievable for them.6 Randomized clinical trials require uniformity and consistency of intervention, and a video lends itself to this kind of rigorous evaluation. However, trying to achieve improvements in the way overall decisions are made and recorded may require more nuanced, mixed-methods evaluation. In supporting the call from Becker et al2 for large randomized clinical trials to investigate the best approaches to facilitate DNR decisions, perhaps future research should focus on the optimal approach to overall treatment plans, rather than DNR in isolation.
