Abstract
Introduction
Most Australians die predictably in acute hospital settings. Despite this, hospitals remain ill-equipped to care for dying patients with hospital deaths not uncommonly perceived as distressing by both patients and their families. A care bundle for the dying was developed with this aiming to report the feasibility of implementing this quality improvement strategy.
Methods
A before and after observational approach was used to compare whether there were changes in care delivery to imminently dying patients in two medical wards. Data were extracted retrospectively from their inpatient files. The main outcome of this work was the percentage compliance with the bundle elements and proportional change from baseline where comparative care processes had previously been in place.
Results
Over 6 months, 90 deaths occurred with the bundle in place for 74.5% (n = 70) with significant increases in regular symptom monitoring and monitoring of family distress seen (p < 0.001, respectively). There was compliance with prescribing guideline for pain in 59.2% (29/49) charts and breathlessness in 53.1% (26/49). In the absence of previous prescribing guidelines it was not possible to comment on the significance of this latter observation.
Discussion
This work highlights that it is feasible to implement and assess a pilot project aimed at improving the quality of care delivered to people dying in acute hospitals. This preliminary work suggests that it is possible to integrate evidence-based care processes into the care of the dying by adopting a care paradigm more typically reserved for critical care. However, more work is required to confirm this in larger studies.
Introduction
Quality health care is care that is considered patient-centered, evidence-based and safe with one of the intentions of such care delivery being the minimisation of iatrogenic harm.1–4 However, there is an increasing body of literature that highlights the fact that people dying in hospitals may be exempt from the same rigorous quality standards expected at other points in disease trajectories,5,6 potentially exposing patients and families to unnecessary risks. For example, data from the UK suggests that up to 60% of people who are in hospital are at risk of distressing physical symptoms especially pain, breathlessness and agitation. 7 Although people wish to die free of such problems, 8 this is seemingly often not the case.9,10 This is problematic not only for the dying person but also for his/her family. This is because previous observations have suggested that when families perceive their relatives’ death as uncomfortable they are more likely to experience more complicated bereavements.11,12
In the Australian context, the fact that quality care at the time of death cannot be guaranteed to all Australians dying predictably in hospital has been raised as a significant issue. Greater than 50% of Australian deaths annually occur in hospital with 80% of these deaths being the predictable consequence of complex, chronic illness. 13 This places approximately 120,000 people per annum at risk of not receiving quality-driven care appropriate to their needs. The most common solution proffered is to increase the numbers of home deaths, but there are issues that currently preclude this. Firstly, like other developed countries, the demographics of Australian society are changing with more people living longer with complex, chronic illness, and as part of progressively smaller family units.14–16 Secondly, community services to support home deaths are limited in their capacity to care for the numbers of Australians dying, 14 and lastly, Australian and international data indicate that for some, hospital is actually the preferred place of death.17,18 Such observations suggest that the trend towards dying in hospital, either by choice or through circumstances, is unlikely to reverse, highlighting a real imperative to address the issue.
The aim of this project was to develop a care bundle for the dying and then test the feasibility of this approach to improving care delivered to people identified as imminently dying in hospital.
Methods
Setting
The project was conducted in two medical units of a regional teaching hospital in NSW (Australia). This hospital has 200 beds and admits over 16,000 people per year in medicine, oncology, hematology, palliative care and surgery.
Patients
The cohort of interest for this work were people who had been identified as transitioning to the last hours to days of life as an expected part of their disease trajectory. For this project, the documentation that supported that people had entered this phase of life was based on one of two types of written documentation. The first was a “not for resuscitation order” that included a written assessment based on poor prognosis, such an intervention would be futile. The second was documentation that outlined that for this person, death was likely to occur shortly.
Quality improvement process
A structured, sequential quality improvement process was chosen for this work which included: (1) an audit to best understand how usual care of the dying was delivered in order to understand the issues within the larger health care system; (2) establishment of a multidisciplinary team to agree on a solution based on the identified problems; (3) engagement of appropriate stakeholders to assist with the implementation of the solution; (4) piloting the change by engaging staff with the delivery of appropriate education, incorporation of the change into routine clinical use and (5) evaluation of the change.

The next step was to operationalise this bundle. The initial step was the development of an appropriate track and trigger chart. With permission, the observation chart alluded to in Table 3 was developed with the intent of having a similar appearance to the currently accepted, NSW state-wide routine observation chart. 23 The main difference was that this new chart omitted usual vital signs (blood pressure, temperature and pulse) and replaced them with numerical analogue scores for problems reported as highly likely to be bothersome for dying people. This included pain, breathlessness, agitation and nausea.24–27 The chart also included the family distress item of the Palliative Care Problem Severity Score (PCPSS), 28 a screening tool used in the majority of Australian palliative care services. Like other track and trigger charts, the care of the dying observation chart included explicit calling criteria to help staff gauge when extra support for the dying person or their family was needed.
The second aspect of the bundle required the development of supporting documentation to allow health professionals to understand what is currently considered optimal prescribing to palliate common physical symptoms at the time of death. This included the development of best-practise prescribing algorithms to inform safe symptom control strategies with these algorithms based on current best available evidence.29–31
Implementing the solution
An implementation plan was devised which included identification of key stakeholders, senior medical and nursing staff, and identification of champions including nurse educators, pharmacists and the medical emergency team. Planned education sessions for as many people as possible were scheduled with the times chosen to be suitable to the working days of these groups.
Overall, 18 sessions were delivered, all of which took the format of face-to-face teaching. The ward nurses required the most sessions, with six sessions targeting a total of 50 nurses. In addition, there were a number of impromptu sessions for nurses who were unable to attend the formal sessions, with this occurring less than 10 times. Other sessions included one for the identified nurse champions for this project (n = 6), one for the medical emergency team (n = 5) combined with intensive care staff (n = 3). Three sessions were conducted with 15 senior medical staff and another with representatives from the hospital’s pharmacy (n = 5). Lastly, four sessions for junior medical officers were held, addressing a total of 21 doctors. Additionally, the project was presented at the hospital’s main education session for doctors, typically attended by approximately 30 people. No assessment of the recall from these sessions was undertaken.
Data collection
Baseline data were collected from a randomly selected cohort of deaths that had occurred from January 2012 to July 2012 inclusively. The bundle was implemented over a 6-month period, commencing July 2013. In order to examine whether the baseline group was similar to the group cared for on the bundle, the following data were collected: demographic details including age; gender; duration of time spent in the terminal phase and cause of death as extracted from the death certificate. The Cumulative Illness Rating Scores were also calculated. 32
For those who died with the bundle in place, and where possible in the audited deaths, the following were collected after the person had been identified as dying:
– Proportions of people who had evidence of regular symptom scores (pain and breathlessness) assessments; – Proportions of families with evidence that staff regularly assessed their needs as shown by completion of the family distress rating scores; – Percentage of times that prescribing for pain and breathlessness correlated with the assessments of the severity of the problems documented by staff. This was extrapolated as a measure of compliance with prescribing recommendations.
Dying patients who were prescribed opioids were identified as being either opioid-naïve or opioid-dependant. Allocation to one of these subgroups was based on whether or not they had been prescribed regular opioid analgesia for more than 7 days before they entered the terminal phase of life. For those who met these criteria, the initial dose of opioid prescribed after dying had been diagnosed was extracted. This was converted to the mean oral morphine equivalent (OME) dose in milligrams (mg) using accepted dose conversion tables.

Statistical analysis
Extracted data were summarised and analysed using Stata (Version 13.1, StataCorp LP, College Station, Texas, USA, 2014). A p value of <0.05 was considered significant. The data from the audit provided the baseline data against which to compare the effects of the bundle. Descriptive statistics were used to summarise patient’s characteristics. Two sample t-tests of means were used to compare ages and days before death. Two sample tests of proportions were used to compare gender and whether a diagnosis of dying had been made. Chi-square tests for univariate frequency distributions were used to compare the cause of death and cumulative illness rating values. Compliance with the whole bundle was measured as a percentage of the total numbers of deaths over 6 months. Compliance with specific elements of the bundle was extracted from the specific cases where it was in use. In order to provide meaningful comparisons of the change between the baseline audit data and the data collected from those deaths that occurred on the bundle, the proportions of people with symptom scores (pain and dyspnoea scores) and family distress scores were compared using Pearson Chi-square statistics. Lastly, the mean OME in mg of people previously opioid-naïve before death was diagnosed were compared using a t-test with unequal variances with the resulting standard deviations compared using the F-statistic.

Compliance with bundle elements
The pre- and post-implementation compliance figures are summarised in Table 5. The cumulative proportions of charts with evidence of monitoring of physical symptoms, family distress and prescribing in accordance with guidelines are summarised in Table 5. The comparison of the proportions of patients with pain scores between the baseline group and post-intervention groups showed a significant difference (0.22 vs 0.70; χ2 with 1 df = 27.9, p < 0.001), as did breathlessness (0.04 vs 0.70; χ2 with 1 df = 52.0, p < 0.001). Lastly, family distress scoring significantly changed (0.00 vs 0.70; χ2 with 1 df = 59.2, p < 0.001). Despite the fact that the frequency of symptom observations had increased, very rarely were observations almost never recorded at the recommended fourth-hourly frequency (Figure 1).

Changes in opioid prescribing
In the baseline group, of the 16 people who fitted this criteria the mean OMED was 90 mg (SD ± 180) compared with 12 people who fitted this criteria where the mean OMED was 55 mg (SD ± 39) after the pilot was commenced. While these figures are insufficient to display a meaningful difference, notably a comparison of the standard deviations of the morphine doses between the two groups using a variance ratio test shows a significant difference (F-statistic with 15 and 11 df = 21.3, p < 0.001). While exploratory, this is suggestive of a reduction in the range of morphine doses being prescribed in the post-implementation group.
Discussion
The aim of this work was to systematically develop, pilot and evaluate a quality improvement approach in order to improving dying hospitalized patients’ access to quality care. This was developed with consideration of consumers’ (i.e. patients and their families) needs, existing evidence and medication safety.
The need for the project was based on a review of the literature and an audit of care with the latter suggesting that the care processes documented in people’s files would not have provided quality care, i.e. care that is patient-centered, safe and evidence-based. The quality improvement solution selected for this site was development and implementation of a care bundle. The results of the work presented here suggest that a care bundle is a feasible approach to improve end-of-life care. This statement is based on the compliance with the initiation of the bundle and the percentage with which the individual elements were completed, particularly tracking of symptoms and family distress.
One of the main intentions of this work was to improve identification and documentation of problems likely to face imminently dying people. Observation charts such as the one developed for this work may play a critical role in supporting staff to document problems and by this action, trigger the most appropriate response. The proportion of people who had documentation of symptoms (especially pain and dyspnoea) and family distress significantly improved from baseline figures, although documentation rarely complied with the recommended fourth-hourly frequency. This failure to monitor physical symptoms at the same frequency of monitoring as usual vital signs (i.e. blood pressure, temperature, pulse rate) has been reported elsewhere in the end-of-life care literature. 35 It is not possible to comment here whether this is detrimental to overall symptom control and this question is only answerable with further work. It is also not possible from the preliminary nature of this project to conclude that better documentation will have resulted in better outcomes for the families’ of dying patients. However, good documentation has been identified as a predictive of better patient outcomes. 36 The last component of the bundle was the implementation of prescribing guidelines to best palliate pain and breathlessness. As such guidelines had not previously been in place, it is not possible to comment if practice had changed.
One of the most significant concerns from the baseline audit was the observation that medication prescribing was highly variable. Most worrying was the observation that at times, prescribing could be considered unsafe given that some people had been commenced on much higher doses of opioids than would be expected when people were opioid-naïve before they entered the terminal phase of life. Once the bundle had been introduced, it was notable that the average doses of opioids prescribed in those who were opioid-naïve at the time of a diagnosis of dying trended lower. Further, the doses were more aligned with recommended doses. 29 However, the small numbers of people to date preclude a more detailed analysis. This work does provide both data to inform sample size calculations for a definitive study and supports the fact that progressing this further is highly feasible.
Strengths of this work
This work, although preliminary, is important for a number of reasons. End-of-life care is not usually seen as the responsibility of health professionals working in acute hospitals but rather the remit of sub-specialty providers such as palliative care services. This belief is paradoxical given that in fact, acute hospitals are the most likely place of death for the majority of people both by choice and circumstance. This pilot work highlights that it is possible to address the care of people dying in hospital and even more importantly, evaluate how this may change the care as documented as delivered. Lastly, this work incorporated accepted approaches to caring for people with complex needs. To date, much of the work that has been undertaken to improve care of the dying has been based on developing separate models not aligned with usual hospital practice. One of the intentions of this quality improvement project was to consider an approach to caring for the dying that reinforces that it is part of usual scope of care provided by acute hospitals. It is imperative to design systems that facilitate care at this time of life delivered with the same attention to quality as at any other time point.
Weaknesses of this work
There are weaknesses with this work. This work is a small non-randomised observational pilot study that compares pre-intervention audit data with post–intervention data. However, comparisons were only possible when at least comparable practices had been in place previously. As such, it does not provide definitive data to support the use of a care bundle to improve end-of-life care. Further, it is not possible to state more than this work has shown an improvement in documentation of people’s symptoms. Definitively recommending this approach will require further research although this work highlights the feasibility of undertaking this necessary research. This work did not allow for clustering despite the fact that it was conducted in a non-randomised fashion in two wards. However, as pilot work, this is acceptable given the baseline data were collected from the same locations prior to introduction of the bundle. The bundle was then introduced simultaneously to the two wards subsequent to which the intervention data was collected. However, the more definitive trial planned to support this approach to care will take this into account.
Future directions
The numbers of people dying in hospital is unlikely to reduce in the imminent future. There is a real need to address the care delivered to people in order to improve the experiences of those imminently dying and their relatives. Further, care at the end of life requires interdisciplinary input to address the issues identified as important to dying people. As with care at any point in disease trajectories, this is best delivered in a coordinated fashion with all involved staff sharing important patient and family information. 37 Coordination of care in such a fashion facilitates the provision of the necessary care required to address the often complex needs of dying people and their families. This project was undertaken with the aim of better observing patients and their families, with the expectation that these observations should trigger the most appropriate response.
Based on the work reported here, a larger body of work is planned. This will include both a stepped-wedge, cluster randomised trial together with qualitative family interviews. This work will be conducted across six hospitals in regional NSW with each hospital contributing 35 deaths each. For this trial, an on-line education resource has been developed with the content of this reinforced by a spaced education program. Completion of this program will be accepted as credentialing, with only those credentialed able to participate in care of the dying.
Lastly, there are other areas of care that represent quality of people facing imminent death not covered in this preliminary work. Acknowledging the breadth of the problem it is possible to conclude that perhaps one of the most important aspects of this work is that it may provide a template to inform other investigators aiming also to improve end-of-life care.
