Objective Patients with advanced diseases and frail older adults often face decisions regarding life-prolonging treatment. Our aim was to provide an overview of the feasibility and effectiveness of tools that support communication between healthcare professionals and patients regarding decisions on life-prolonging treatments in hospital settings.

Design Systematic review: We searched PubMed, CINAHL, PsycINFO, Embase, Cochrane Library and Google Scholar (2009–2019) to identify studies that reported feasibility or effectiveness of tools that support communication about life-prolonging treatments in adult patients with advanced diseases or frail older adults in hospital settings. The Mixed Methods Appraisal Tool was used for quality appraisal of the included studies.

Results Seven studies were included, all involving patients with advanced cancer. The overall methodological quality of the included studies was moderate to high. Five studies described question prompt lists (QPLs), either as a stand-alone tool or as part of a multifaceted programme; two studies described decision aids (DAs). All QPLs and one DA were considered feasible by both patients with advanced cancer and healthcare professionals. Two studies reported on the effectiveness of QPL use, revealing a decrease in patient anxiety and an increase in cues for discussing end-of-life care with physicians. The effectiveness of one DA was reported; it led to more understanding of the treatment in patients.

Conclusions Use of QPLs or DAs, as a single intervention or part of a programme, may help in communicating about treatment options with patients, which is an important precondition for making informed decisions.

Statistics from


Patients with advanced disease and older frail adults often face difficult decisions regarding life-prolonging treatment in hospital settings, such as starting, continuing or stopping palliative chemotherapy, antibiotics, artificial feeding and hydration.1 2 These treatments have no curative intent and may have limited benefit besides prolongation of life or symptom management. Furthermore, they may have harmful side effects and lead to a reduction in the quality of life.3–5

Decisions on starting or stopping life-prolonging treatment are often preference sensitive.6 7 There is often no evidence for the superiority of one option over another and the best choice depends on how the individual values the risks and benefits of different options.8 9

Ideally, decisions regarding life-prolonging treatment are made by reaching agreement between the patient (and family), nurses and physicians, following discussion of the treatment options.10 The process of shared decision making can support these discussions by helping both patients and healthcare professionals to explicitly consider the patient’s value trade-off in light of the existing treatment options, including the option of taking no action, and incorporate this trade-off in a final decision.6 11 12 The role of healthcare professionals in shared decision making is to convey, prioritise and structure all the relevant information relating to the different treatment options and elicit and discuss the patient’s values and preferences.11 13

Currently, decisions about life-prolonging treatment are often made in a dialogue between the patient and the physician, with nurses sometimes having a supporting role.14 15 Physicians often avoid discussing the option of stopping or forgoing life-prolonging treatment and can be uncertain about how to discuss end-of-life topics and patients’ incurable status.16–18 This in turn can lead to inappropriate treatment decisions, such as continuing aggressive treatment in patients whose personal values and needs are overlooked.19 20

In order to facilitate communication and decision making, a multitude of tools have been developed, such as option grids, decision aids (DAs) and question prompt lists (QPLs). These tools have been developed and tested mainly for medical (curative) treatment decisions and screening.21–23 Several tools have been developed to support decision making in end-of-life issues;24–26 however, they are often focused on (advance) care planning27 28 or on decision making in hypothetical situations instead of actual decisions about treatments that have no curative intent, though they may affect quality of life.29 Due to advances in technology and an increase in the number of frail older adults, we expect an increasing challenge in finding a balance between clinical imperatives to treat and aligning decisions with the person’s preferences in the context of their life-limiting condition. Therefore, the objective of our review was to provide an overview of the feasibility and effectiveness of tools that support healthcare professionals and patient (and family) communication regarding decisions on life-prolonging treatments in hospital settings based on a broad range of study designs. Our research questions were: (1) What evidence exists on the feasibility of tools that support the communication regarding life-prolonging treatment options between patients, family members and healthcare professionals in hospital inpatient and outpatient clinics? (2) What evidence exists on the effectiveness of these tools?



A systematic review of the literature was conducted to identify studies that examined tools that support communication between patients, family and healthcare professionals about life-prolonging treatments and/or quality-of-life decision for hospitalised patients. This systematic review was conducted and reported in line with the Preferred Reporting Items for Systematic Reviews (PRISMA) statement30 (online supplemental material 1) and registered in PROSPERO (CRD42019120908), available at

Search strategy

PubMed, CINAHL, PsycINFO, Embase and the Cochrane Library were systematically searched for the period up to 11 December 2018 (PubMed, CINAHL and PsycINFO) and 10 January 2019 (Embase and the Cochrane Library). We also searched for additional references in Google Scholar on 11 January 2019. The full search strategies are provided in online supplemental material 2. In addition, we consulted 16 international experts in shared decision making or end-of-life care to ask for any additional tools and we checked the reference lists in the included studies.

Eligibility criteria

We selected studies published between January 2009 and January 2019. This time frame was chosen in agreement with experts and in line with previous reviews,24 25 because we wanted to find tools that are still relevant and are used in common clinical practice. This included tools that were developed before 2009 but are still being used in later studies. Original studies were eligible for inclusion if they focused on tools that support treatment decisions in hospital inpatient or outpatient settings in adults (aged 18 or older) in the last phase of life, in other words have an advanced incurable disease or are frail and elderly; on communication about decisions on life-prolonging treatment between patients and healthcare professionals (at least) and on outcomes regarding the feasibility (adoption, usage or satisfaction with use) of the tool or outcomes regarding the effects on patients, family and/or healthcare professionals.

Studies were excluded if the tool focused on populations with dementia or other cognitive problems, due to the barriers in communication and reduced decisional capacity, which influences the dialogue31 or did not focus on actual treatment decisions, but only on future possible situations, such as regarding cardiopulmonary resuscitation.

We did not apply restrictions beforehand regarding the publication language.

Study selection

Duplicates were removed using EndNote X8 (by MT). Subsequently, in Endnote, we restricted the time frame to 10 years. Titles and abstracts were screened to determine whether studies were potentially eligible by two researchers (MT and IJ), with the aid of the programme Rayyan (Qatar Computing Research Institute).32 In the next selection step, the full texts were screened by two researchers (MT and IJ) to determine if studies fulfilled the eligibility criteria. Differences in opinions about inclusion were resolved through discussion with two other researchers (HP and AF). The study selection procedure and results can be found in the flowchart in figure 1.

Data selection

Two researchers (MT and IJ) independently extracted the data from the included studies using a predefined form. Disagreements were resolved through discussion. The following study characteristics were extracted: country, study design, study aims, setting (inpatient or outpatient), study population, number of participating patients and/or healthcare professionals and the age (mean or median) of the participants.

On feasibility, we extracted data on the evaluation of the content and usage. For effectiveness, we extracted data on outcomes measured in patients, family or healthcare professionals, related to use of the tool.

Quality assessment

Studies that met the inclusion criteria were independently evaluated by two researchers (MT and IJ) for methodological quality using the Mixed Methods Appraisal Tool (MMAT), V.2018.33 This tool has been proven to be effective for systematically assessing the quality of studies with quantitative designs (randomised controlled trials, non-randomised trials and quantitative descriptive studies) or qualitative designs and mixed methods studies. Each study was assessed within its methodological domain and scored on five core quality items. The presentation of overall scores from the ratings is not generally recommended, since information on problematic aspects is lost.33 34 However, for clarity and interpretation, we decided to report the MMAT scores for the included articles, ranging from 0% (none of the criteria are met) to 100% (all criteria are met). Again, in the case of discrepancies in the quality assessment, the researchers (MT and IJ) reached consensus through discussion.

Data synthesis

Data on feasibility and effectiveness were tabulated. We decided a priori not to do a meta-analysis because of expected heterogeneity in study design and in outcomes measured. Instead, we provide a narrative summary, by conducting a qualitative synthesis to identify key themes.


The search retrieved 10 589 references. After removing duplicates and imposing a date restriction, we identified 3816 references in total for screening the title and abstract for eligibility (figure 1). Most of these references (3762) were excluded during screening, mainly because they did not include a tool supporting treatment decisions or because they did not focus on adult patients in the last phase of life without dementia or other cognitive impairments. After reading the full texts of the remaining 53 references, 7 studies18 35–40 met the criteria of our review.

The included studies were all conducted in adults with advanced cancer in outpatient hospital settings. The publication dates of these studies ranged from 2010 to 2019. The studies took place in Australia,35 36 the USA38 40 the Netherlands,39 both Australia and Canada18 and both Australia and the USA.37 In total, 520 patients (min 27, max 207), 105 relatives (min 11, max 80) and 42 healthcare professionals (min 6, max 13) were included in the studies. Median age of included patients varied from 55 to 72 years. Table 1 shows the main characteristics of the seven included studies in this review.

Study characteristics

Quality assessment

Quality assessment scores using the MMAT ranged from 40% (two criteria met)39 40 to 80% (four criteria met).36 37 The quality assessment for each study is presented in online supplemental material 3. The overall quality of the included studies was assessed as moderate to high (online supplemental material 4-table 2). Studies that focused on effectivity used mainly validated tools such as the Functional Assessment of Cancer Therapy-General41 or the Control Preferences Scale.42 In only one of the quantitative studies, a sample size was calculated.18

Tools for supporting decisions

Five out of seven (online supplemental material 4-table 2) studies describe QPLs as tools to support the communication about decisions on life-prolonging treatment.35–39 In two studies, stand-alone QPLs were used37 38 while in three other studies, a QPL was used as part of a support programme.35 36 39 Two studies describe DAs that were used in the interaction between patients, physicians and nurses during consultations.18 40

The stand-alone QPLs consisted of a booklet37 or a single-page checklist.38 Both were tested in adults with advanced cancer with the intention of preparing them prior to consultation with their physician.

Three studies involved a QPL, in the form of a booklet, as part of a support programme.35 36 39 Besides the QPL, these programmes consisted of a patient communication aid in the form of a brochure39 or a nurse-led communication support programme consisting of a face-to-face meeting, a follow-up phone call36 or a DVD discussing advance care planning.35 The programmes were designed to increase participants’ ability and motivation to discuss prognosis and end-of-life care.

The DAs18 40 consisted of a booklet, either with accompanying narration on an audiotape or compact disc18 or for use in an interactive process with a physician and a nurse.40 The DAs were designed to improve participants’ quality of decision making in interaction with physicians and nurses.

Three of the seven studies of QPLs were performed by Walczak et al35–37 and contained the same QPL, but elements were added in each study and different outcomes were assessed. Therefore, we included the three publications of Walczak et al as separate studies in our review.

Feasibility of tools for supporting decisions

In six studies, the feasibility of the tools (online supplemental material 4-table 2) was assessed with respect to their acceptability and usefulness.35–40 Both QPLs (either as a stand-alone QPL or as part of a multifaceted programme) and DAs were considered useful, acceptable and comprehensive by patients and family,37–40 nurses40 and physicians.37 38 40 In one study, separate versions of the QPL were developed in two Western countries to accommodate differences in population and culture.37 In one programme, QPL was explicitly used by patients in 41% of consultations.39 About two thirds of patients intended to use the QPL.36 Use of a programme with QPL and a DVD did not interrupt work processes or influence consultation length.35

Effectiveness of tools for supporting decisions

In three of the seven studies, effectiveness was evaluated for a QPL that stand alone,38 a QPL in combination with a programme and DVD35 or a DA18 (online supplemental material 4-table 2). Use of just a QPL (single intervention) significantly decreased patient anxiety as measured before and after consultation (mean anxiety scores (scale of 20–80) were 46.0 previsit and 39.6 postvisit, p=0.005).38 Patients receiving the combined QPL package (including a programme and DVD) showed greater self-efficacy in communication (knowing what questions to ask) and gave more cues for discussion during the consultation compared with patients receiving standard care.35 In the evaluation of both the QPLs and the DA, no significant differences were found in patient involvement in decision making,18 35 38 patient or physician satisfaction18 or quality of life.18 35 Use of a DA with accompanying narration increased patients’ understanding of therapy and survival outcomes.40


In this review, we aimed to provide an overview of tools that support healthcare professionals and patients (and family) in communication regarding decisions on life-prolonging treatments in hospital settings. We found seven studies reporting on the feasibility and effectiveness of tools that support communication regarding decisions on life-prolonging treatments in outpatient hospital settings. In five studies, the tool consisted of a QPL, either as a stand-alone tool or as part of a multifaceted programme. In two studies, the tool consisted of a DA for use during consultation. Both QPLs and DAs were considered feasible by both patients and healthcare professionals. Furthermore, use of a QPL by adults with advanced cancer and by healthcare professionals resulted in decreased patient anxiety and increased cues from patients for discussing end-of-life care with physicians, while use of a DA increased patients’ understanding of treatments and outcomes.

The overall quality of the seven studies was appraised as moderate to high. The studies differed in methodology (design and execution) and in outcomes. Six studies evaluated the feasibility of the intervention, whereas the effectiveness of the tools in helping decide about life-prolonging treatments was only determined in three studies. The scarcity of available evidence on the effectiveness of tools is in line with other reviews, which conclude that tools are generally acceptable, however are rarely evaluated for effectiveness.24 43

The three studies that measured effectiveness provided evidence that a QPL (as a stand-alone tool or as part of a multifaceted programme) decreased patient anxiety and increased the cues given by patients for discussing the end of life, while the use of an interactive DA enhanced patients’ understanding and knowledge. The decrease in anxiety was found over the course of a visit in patients with advanced cancer. A review regarding decision making on curative treatments suggested that use of QPL had no consistent effect on patient anxiety, although unintended effects seem unlikely.23 The latter is confirmed in our review within the specified context of end-of-life care. The three studies did not find any effect of the QPLs or DA on the process of decision making, decisional regret, patients’ and physicians’ satisfaction or the quality of life. This is in line with other reviews, which conclude that tools improve patients’ question asking and knowledge, but did not find effects on decisional preferences or regret.16 22 23 43 44

The QPLs and DAs described in the studies included in this review were developed and tested in adults with advanced cancer in outpatient hospital settings. However, decisions regarding life-prolonging treatments are also relevant for patients with other advanced diseases, such as advanced stages of chronic obstructive pulmonary disease, chronic heart failure,45 chronic kidney disease46 or liver disease.47 It is known that in adults with advanced diseases, options for starting, stopping or forgoing life-prolonging treatments are often discussed only at a late stage due to discomfort about addressing end-of-life issues and uncertainty about the timing of such discussions.16 45 48 Besides, healthcare professionals are often uncertain about how to address a poor prognosis or a short life expectancy, which might result in them avoiding these topics, even though those conversations may have consequences for treatment decisions.16–18 Use of QPLs (whether as a stand-alone tool or integrated in a programme) or DAs may help patients, their family and healthcare professionals to discuss these issues in relation to decision making about life-prolonging treatments.

In three studies in our review, nurses were explicitly involved in the decision-making process.35 36 40 Besides, family was explicitly mentioned in three out of seven included studies.36 38 39 This complies with patients’ desire for nurses and family to be involved.44 The role of nurses is described elsewhere as educating patients about treatments and side effects, advocating on patients’ behalf and coaching them in decision making,12 15 49 50 and nurses are seen as valuable and influential in decision making about life-prolonging treatment.51–53

The tools in the studies all involved written material. It can therefore be expected that their feasibility might be less in populations that might also be under-represented in the study samples, such as adult migrant groups who are not native speakers of that language or people with limited health literacy.54 55 Therefore, QPLs, DAs and other supporting tools should be adapted to and evaluated in diverse populations, including groups with different cultural backgrounds and people with limited health literacy.55

Strengths and limitations of the study

A methodological strength of this review is the search in a variety of relevant literature databases combined with consultation of international experts to identify relevant studies.

Nevertheless, we were able to include only seven studies. We do not think our selection strategies were too narrow, but see this as an indication that there is a scarcity to date of tools for supporting decisions on life-prolonging treatments in patients with advanced diseases and frail older people. Another limitation concerns the fact that the included studies had a variety of designs and outcome measures, which made it impossible to perform statistic pooling. Furthermore, one study that measured effectivity had a small sample (n=30), but nevertheless did find statistical significant differences in anxiety. The results are hopeful but should be confirmed by future studies.


This systematic review reveals that the use of QPLs and DAs, as a single intervention or as part of a programme, may help in communicating about treatment options with patients, which is an important precondition for making informed decisions about life-prolonging treatment in adults with advanced cancer in hospital settings. QPLs and DAs were considered feasible by both patients and healthcare professionals. QPLs reduced patient anxiety and improved patients’ cue asking, while a DA improved patients’ understanding.

Further high-quality studies are needed to increase knowledge about the feasibility and effectiveness of such tools, particularly in populations with advanced diseases other than cancer, as well as in frail older people. Also, more attention has to be given to whether the use of the tools improves patient outcomes and supports patients’ preferences.
