Abstract
Background: The guideline-recommended elements to include in discussions about goals of care with patients with serious illness are mostly based on expert opinion. We sought to identify which elements are most important to patients and their families.
Methods: We used a cross-sectional study design involving patients from 9 Canadian hospitals. We asked older adult patients with serious illness and their family members about the occurrence and importance of 11 guideline-recommended elements of goals-of-care discussions. In addition, we assessed concordance between prescribed goals of care and patient preferences, and we measured patient satisfaction with goals-of-care discussions using the Canadian Health Care Evaluation Project (CANHELP) questionnaire.
Results: Our study participants included 233 patients (mean age 81.2 yr) and 205 family members (mean age 60.2 yr). Participants reported that clinical teams had addressed individual elements of goals-of-care discussions infrequently (range 1.4%–31.7%). Patients and family members identified the same 5 elements as being the most important to address: preferences for care in the event of life-threatening illness, values, prognosis, fears or concerns, and questions about goals of care. Addressing more elements was associated with both greater concordance between patients’ preferences and prescribed goals of care, and greater patient satisfaction.
Interpretation: We identified elements of goals-of-care discussions that are most important to older adult patients in hospital with serious illness and their family members. We found that guideline-recommended elements of goals-of-care discussions are not often addressed by health care providers. Our results can inform interventions to improve the determination of goals of care in the hospital setting.
In Canada, dying is often an in-hospital, technology-laden experience.1–4 Rates of cardiopulmonary resuscitation (CPR) before death continue to increase among older adult patients in hospital,5 and one-fifth of deaths in hospital occur in an intensive care unit.1,2,6,7 These observations contrast sharply with patient-reported preferences. A recent Canadian study found that 80% of older adult patients in hospital with a serious illness prefer a less aggressive and more comfort-oriented end-of-life care plan that does not include CPR.8
Such patients and their families have identified communication with health care providers and decision-making about goals of care as high priorites for improving end-of-life care in Canada.9,10 We define “decision-making about goals of care” as an end-of-life communication and decision-making process that occurs between a clinician and a patient (or a substitute decision-maker if the patient is incapable) in an institutional setting to establish a plan of care. Often, this process includes deciding whether to use life-sustaining treatments.11 Current guidelines recommend that health care providers address 11 key elements when discussing goals of care with patients and families (Box 1).12–14 However, these elements are mostly based on expert opinion and lack input from patients and their families.
Key elements of goals-of-care discussions with patients in hospital with serious illness12–14
Ask about previous discussions or written documentation about the use of life-sustaining treatments
Offer a time to meet to discuss goals of care
Provide information about advance care planning to review before conversations with the physician
Disclose prognosis
Ask about patients’ values (i.e., what is important to them when considering health care decisions)
Provide information about outcomes, benefits and risks of life-sustaining treatments
Provide information about outcomes, benefits and risks of comfort measures
Prompt for additional questions about goals of care
Provide an opportunity to express fears or concerns
Ask about preferences for care in the event of a life-threatening illness
Facilitate access to legal documents to record patients’ wishes
Our primary objective was to determine which of these elements are most important to patients and their families. In addition, we examined whether these discussions were associated with concordance between patients’ (or family members’) preferences and prescribed goals of care, and with satisfaction with end-of-life communication and decision-making.
Methods
Setting and design
Our research program includes periodic audits of end-of-life communication and decision-making.8 Between Jan. 16, 2013, and June 28, 2013, we interviewed eligible patients and their family members at 9 Canadian acute care hospitals in British Columbia, Alberta, Ontario and Quebec using a validated questionnaire.15 We have previously reported data from the first audit cycle pertaining to end-of-life discussions before admission to hospital.8 Here, we report data from the second audit cycle that pertain to goals-of-care discussions that took place during the index hospital stay.
This study was approved by the research ethics board at each of the participating institutions.
Participants
Our eligibility criteria have been published previously.8 Briefly, we enrolled patients in hospital who were at high risk of dying within the next 6 months and their family members. We defined high risk as either 55 years of age or older with an advanced stage of one or more specific conditions (chronic obstructive pulmonary disease, congestive heart failure, cirrhosis, cancer and dementia) or 80 years of age or older with admission to hospital for an acute condition. If these criteria were not met, we deemed patients eligible if a member of their clinical team would not be surprised if the patient died within the next 6 months.
All eligible patients were admitted to a medical service, not an intensive care unit, of a participating hospital. We excluded patients who were unable to communicate because of cognitive impairment and patients who spoke neither English nor French.
We defined family members as people who knew the patient best, including partners, significant others and close friends, and who had visited the patient in hospital at least once. We excluded paid caregivers from this definition. The same criteria were used to identify and invite family members of eligible but nonparticipating patients. To obtain a representative sample, we planned to enroll 30 patients and 30 family members at each of the 9 participating sites.
Eligible patients were identified by treating teams or by research staff who screened hospital records. When research staff were available, we approached consecutive, eligible patients and their family members for consent. We enrolled patients 2–5 days after their admission to hospital so that presenting symptoms would have abated enough to allow the patient to participate in an interview. All participants provided written informed consent.
Study questionnaire
The questionnaire we used to audit end-of-life communication and decision-making practices has previously been shown to have face and content validity, good ratings of clarity and low psychological burden.15 Research staff interviewed patients and family members separately. We asked participants whether, since admission, a member of the care team had discussed 11 key elements of determining goals of care (Box 1), and to rate how important it was for each of these elements to be discussed with a member of the care team. Response options were “not at all important,” “not very important,” “somewhat important,” “very important” or “extremely important.”
We determined the 11 elements of goals-of-care discussions from a literature search for clinical practice guidelines regarding end-of-life communication and decision-making and from responses given during a focus group.12–14 The focus group consisted of 25 experts in critical care, internal medicine, palliative care, nursing, research methods and psychometrics.12
To assess satisfaction with end-of-life care, we used the validated Canadian Health Care Evaluation Project (CANHELP) questionnaire.16 This questionnaire asks participants to rate satisfaction with specific aspects of care during the previous 4 weeks as follows: 1, not at all satisfied; 2, not very satisfied; 3, somewhat satisfied; 4, very satisfied; 5, completely satisfied. The CANHELP instrument has good correlation with global ratings of satisfaction (0.49 and 0.63 for patient and family versions, respectively), and the domains pertinent to end-of-life communication and decision-making used in our analyses have high internal consistency (Cronbach’s α 0.84–0.91).16
Finally, we asked participants to state their preferences as to whether life-sustaining treatments should be used if their condition (or their loved one’s condition) were to deteriorate to the point of becoming life threatening. Response options were as follows: “artificial life-sustaining treatments, including CPR, to keep me alive at all costs”; “full medical care, but no CPR in the event that my heart or breathing stops”; “physicians will be focused on my comfort by alleviating suffering and not on keeping me alive by artificial means or heroic measures, such as trying to prolong my life with CPR and other life-sustaining technologies”; “a combination of these options (e.g., try to fix problems, but if I am not getting better, switch to focusing only my comfort, even if it hastens death)”; and “unsure.” Immediately after the interview, the research staff abstracted data from the patients’ medical records about orders for use or nonuse of life-sustaining treatments and categorized them in the same way as participants’ preferences.
Statistical analysis
We used descriptive statistics (mean, standard deviation [SD] and range for continuous data; counts and proportions for categorical data) to report characteristics of the study participants. We used counts and proportions to report the frequency of discussions about each of the 11 elements of determining goals of care.
Our primary analysis describes participants’ ratings of the importance of the individual elements of goals-of-care discussions. Missing responses were excluded from these analyses (we did not impute data). We ranked each element in order of importance based on the frequency of “very important” or “extremely important” ratings. We used the Spearman correlation coefficient to assess the correlation between patients and family members of the ranking of the 11 elements.
We conducted a secondary analysis to measure the association between occurrence of the elements of goals-of-care discussions and (i) concordance between goals of care preferred by participants and those prescribed in the medical record and (ii) participants’ satisfaction with end-of-life communication and decision-making. When there was no prescription for goals of care in the medical record, we assumed that prescribed goals of care encompassed CPR, because this is the default option in most Canadian hospitals. We measured concordance between preferences and prescribed goals of care using crude and chance-corrected agreement (κ).17 To measure satisfaction with end-of-life communication and decision-making, we calculated an overall score from domains of the CANHELP instrument identified a priori as pertinent to end-of-life communication and decision-making, according to the expert opinion of the investigators. These domains were relationship with physicians, communication and decision-making (Appendix 1, available at www.cmaj.ca/lookup/suppl/doi:10.1503/cmaj.140673/-/DC1). This overall score is the unweighted average for all answered questions within these domains. The score was rescaled to range from 0 (worst possible value) to 100 (best possible value).
We sought to determine whether there was an association between the number of key elements included in goals-of-care discussions and both (i) concordance between patients’ (or family members’) preferences and prescribed goals of care and (ii) CANHELP satisfaction scores. We used logistic regression, with separate models for patient and family member data, to quantify the association between the number of elements that were discussed (predictor variable 0–11) and concordance (dependent variable). We used linear regression to quantify the association between the number of elements discussed (predictor variable) and CANHELP scores (dependent variable). We adjusted our models for age, sex and education, and incorporated hospital site as a random effect to account for clustering of data within hospitals. We used SAS version 9.3 for all analyses.
Results
Study population
Of the 376 patients and 278 family members we approached to participate in the study, we enrolled 233 patients (62.0%) and 205 family members (73.7%). Of the 205 family members who participated, 94 (45.9%) corresponded to a participating patient; 111 (54.1%) of the family members did not correspond to a participating patient, either because the patient met exclusion criteria (n = 96) or because the patient chose not to participate (n = 15) (Figure 1). The average age of participating patients was 81.2 years, and 134 were women (57.5%). The average age of family members was 60.2 years, 158 were women (77.1%), and 125 were the son or daughter of a patient (61.0%) (Tables 1 and 2).

Discussions about and importance of key elements of determining goals of care
Between admission to hospital and the time of the interview (median 3.0 d), patients reported that 1.4 (SD 2.1, median 0) of our 11 key elements were discussed. Family members reported that 2.0 (SD 2.4, median 1) of the 11 elements were discussed (Table 3). Patients and family members ranked the same 5 elements as most important, based on the frequency of “very important” or “extremely important” ratings (Spearman correlation coefficient 0.84; p = 0.001) (Table 3). For patients, the top-ranked element was to be “asked about preferences for care in the event of a life-threatening illness.” For family members, the top-ranked element was discussing prognosis. Both patients and families rated the provision of information about advance care planning and related legal documents as the least important elements. Importance ratings were missing for 8%–16% of patients and 3%–15% of family members.
Discussions about and importance of individual elements in determining goals of care
Association between discussion of recommended elements of determining goals of care and outcomes
Concordance between prescribed goals of care and patient preferences for use (or non-use) of life sustaining treatments was 29.7% (κ = 0.11). Concordance between prescribed goals of care and family members’ preferences for their loved one was 35.6% (κ = 0.18) (Figure 2). Concordance could not be assessed for 21 (9.0%) patients and 11 (5.4%) family members because of missing preference data. Satisfaction with end-of-life communication and decision-making as represented by CANHELP scores was high for patients ( mean 70.9 ± SD 18.9) and family members (mean 64.7 ± SD 22.8). Scores were missing for 14 (6.0%) patients and 6 (2.9%) family members.
(A) Concordance between patients’ stated preferences for life-sustaining treatment and prescribed orders for goals of care (agreement = 29.7%, κ = 0.11). (B) Concordance between family members’ stated preferences for life-sustaining treatment for the patient and prescribed orders for goals of care (agreement = 35.6%, κ =0.18). Blue highlighting shows concordance. A total of 21 patients and 11 family members were excluded because of missing preference data. Note: 1 = aggressive use of heroic measures and artificial life-sustaining treatments, including cardiopulmonary resuscitation (CPR), to keep patient alive at all costs; 2 = full medical care, but no CPR if the patient’s heart or breathing stops; 3 = a combination of the first 2 options (e.g., try to fix problems; if patient shows no improvement, switch to focusing only on patient comfort, even if it hastens death); 4 = doctors will focus on patient comfort and alleviating suffering, not on keeping patient alive by artificial means or heroic measures, such as trying to prolong life with CPR and other life-sustaining technologies; 5 = no documented goals of care.
Discussion of a greater number of the 11 recommended elements of determining goals of care was significantly associated with concordance between participants’ preferences for use (or non-use) of life-sustaining treatments and prescribed goals of care (patient adjusted odds ratio [OR] 1.27, 95% confidence interval [CI] 1.09–1.47, p < 0.001; family member adjusted OR 1.20, 95% CI 1.03–1.39, p = 0.01) (Figure 3). Similarly, discussion of a greater number of the 11 recommended elements was significantly associated with greater satisfaction with end-of-life communication and decision-making, with a 1.4-point increase in CANHELP scores per element discussed among patients (p = 0.03), and a 2.3-point increase per element discussed among family members (p = 0.002).
Concordance between (A) patients’ and (B) family members’ preferences for care at end of life and documented goals of care versus the number of components of determining goals of care that were reported to have been discussed. The line of best fit was calculated using logistic regression (odds ratios) and represents the predicted increase in concordance as more elements of goals-of-care discussions are addressed.
Interpretation
In this cross-sectional multicentre study, we have identified elements of goals of care discussions with health care providers that are most important to older adult patients admitted to hospital with serious illnesses and their family members. The 5 most important elements to discuss were preferences for care in the event of life-threatening illness, values, prognosis, fears or concerns, and additional questions about goals of care. We found that these elements are infrequently discussed and that concordance between preferred and prescribed goals of care is low. Moreover, our results suggest that concordance between preferences and prescribed goals of care, as well as satisfaction with end-of-life communication, increase with the number of elements discussed. Thus, our findings could be used to identify important opportunities to improve end-of-life communication and decision-making in the hospital setting.
Guidelines about end-of-life communication acknowledge that, because of limitations in the available evidence, the recommended elements of goals-of-care discussions are mostly based on expert opinion.12–14 To address this knowledge gap, we used content validation by experts to derive from these guidelines a set of 11 key elements of goals-of-care discussions. Our study provides empirical data to show that discussion of these 11 elements is associated with greater concordance between preferred and prescribed goals of care, and with greater satisfaction with end-of-life communication and decision-making. Furthermore, we have identified which of these elements are most important to patients and family members, an important perspective previously lacking from the guidelines.
We recently published a conversation guide that encourages clinicians to “Just Ask” patients about their goals of care.19 Our results build on that work by providing further direction on which specific elements should be discussed with patients and families in hospital. For example, both patients and family members rated prognostic disclosure as highly important. Indeed, prognostic disclosure is associated with greater satisfaction with end-of-life communication and decision-making.20 However, we found that prognosis was discussed with only 10% of patients and 17% of family members in our study. This is consistent with previous work that showed prognostic disclosure occurs infrequently among patients with serious illness8,20 and represents an important opportunity for improvement.
Our results highlight ongoing challenges in the alignment of prescribed goals of care with patient preferences for end-of-life care. More than 20 years ago, the landmark Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatment (SUPPORT) identified important gaps between patient preferences for end-of-life care and the actual care received.21 In addition, a recent audit in Canadian hospitals found only 30% agreement between patient preferences and prescribed goals of care.8
Strengths and limitations
We used real-time face-to-face interviews, which would be expected to have a lower risk of recall bias than postdischarge questionnaires, and a validated questionnaire to gather our data.
Participants were required to speak either English or French, and most of our participants were white. As a result, the applicability of our results to more diverse populations who do not speak English or French as a first language and who may have different values related to end-of-life care22,23 remains uncertain.
Although we were able to enroll most of the eligible patients and family members (62% and 74%, respectively), thus minimizing selection bias, non-consenting patients or family members may have had different perspectives on what is important during end-of-life communication and decision-making.
We focused on goals-of-care discussions only during the early phase of the hospital stay. Although this is an important time to establish goals of care for patients at high risk of dying, our data may underestimate the frequency of these discussions, which may occur throughout the patient’s stay.
Conclusion
We have identified the guideline-recommended elements of goals-of-care discussions that are the most important to older adults patients in hospital with serious illness and their family members. However, these elements are infrequently addressed by health care providers in hospital, which may contribute to the identified gap between preferred and prescribed goals of care. Our results can inform interventions to improve end-of-life discussions in the hospital setting and the concordance between preferred and prescribed goals of care.
