Abstract
Background:
The Liverpool Care Pathway for the Dying Patient (LCP) aims to transfer hospice principles of care for dying patients to other health-care sectors. This post-bereavement survey explored the LCP’s effectiveness in improving quality of care for cancer patients.
Methods:
Postal self-completion questionnaires were sent to 778 next-of-kin to consecutive deceased patients who had died an ‘expected’ cancer death in a hospice and acute tertiary hospital.
Results:
Following exclusions (n=53), 255 of the 725 next-of-kin agreed to participate (35.2% response rate). Overall hospice participants reported the best quality of care, and hospital participants, for whom care was not supported by the LCP, reported the worst quality of care. Multivariate analysis showed the hospice was an independent predictor for patients being treated with dignity (OR 8.46) and receiving adequate family support (OR 7.18) (P<0.0001). Care supported by the LCP and the hospital specialist palliative care team were both associated with good family support, but neither was an independent predictor.
Conclusions:
From the bereaved relatives’ perspective, within the hospital, the LCP is effective in improving specific aspects of care, such as symptom control for dying patients. Further improvement is required, however, to attain the hospice standard of care.

Main
Recent end-of-life care policies at both national and international level have focused on enabling more people to die in their preferred place of care, which generally is at home (Department of Health, 2008a; Commonwealth of Australia, 2010). Although patients with terminal cancer can have a more predictable disease trajectory compared with non-malignant illnesses, difficulties in accurate prognostication mean a significant proportion of cancer patients will continue to die in the acute hospital (Dunlop et al, 1989; Auret et al, 2003). Although a small but steady increase in the proportion of home deaths (from 18.3 to 20.8%) occurred within the United Kingdom between 2004 and 2010 (Gomes et al, 2011a), the majority of patients within many developed countries, including the United Kingdom, continue to die in hospitals (Costantini et al, 2000; Yang et al, 2006; Gomes and Higginson, 2008b).
Evidence over the last 30 years has demonstrated many shortcomings in the provision of care for dying cancer patients within the acute sector (Field, 1989; Mills et al, 1994; Addington-Hall and O’Callaghan, 2009). Basic principles of palliative care have not always been practised, often resulting in insufficient symptom control, poor communication and inadequate psychological support for patients and their families (Ellershaw et al, 1997a). One initiative introduced to try to improve care for the dying was the Liverpool Care Pathway for the Dying Patient (LCP) (Ellershaw and Wilkinson, 2011b). The LCP is an integrated care pathway that aims to transfer the principles of hospice care, generally regarded as the standard of excellence, into other settings in a format familiar to the main stream health-care system. The LCP was recommended in a recent national UK policy initiative, ‘The Route to Success in end-of-life care in acute hospitals’, (National End of Life Care Programme, 2010) specifically linked with the End-of-life Care Strategy (Department of Health, 2008a), and was also highlighted within the General Medical Council (GMC) guidance as a document to help facilitate decision-making and support care for those who are in the last days of their life (General Medical Council, 2010). Recently, however, criticism and potential misrepresentation of the LCP has featured heavily within the UK media.
Previous work demonstrated that UK health-care professionals perceive the LCP to have a positive impact on patients and families, and help improve staff confidence levels when caring for dying patients (Jack et al, 2003). Similar findings were seen in a recent New Zealand study where the LCP was introduced in two acute hospital wards; staff perceived that the LCP had a positive benefit on end-of-life care, assisting with decision-making, communication and symptom control (Clerk et al, 2012). Results from a pre- and post-comparison LCP study in the Netherlands have indicated that from the bereaved relatives’ perspective, symptom control and some aspects of communication are improved (Veerbeek et al, 2008). Further testing of the LCP’s effectiveness in improving care and support for dying patients and their families from the user perspective has not been undertaken within the United Kingdom. In order to assess the effectiveness of the LCP in transferring hospice care into the acute sector, the primary aim of this study was to compare bereaved relatives’ perspectives about the quality of care in the last days of life for all ‘expected’ cancer deaths in a UK hospice and acute hospital currently using the LCP. In particular, two key outcome measures were assessed: whether the patient was treated with dignity and respect, and whether the family was adequately supported.
Materials and methods
A post-bereavement survey was conducted with next-of-kin to cancer patients who had died within the chosen hospice or acute tertiary hospital in Liverpool. All consecutive patients who had died within a 21-month period (during 2005 or 2006) were included according to the following eligibility criteria:
-
i)
over 18 years of age;
-
ii)
had an ‘expected death’ defined as either having their care supported by the LCP (version 11) or had a ‘Not for resuscitation’ decision documented, and the cause of death on the death certificate was not sudden in nature.
Database records of all the deaths and patients’ next-of-kin were cross-referenced against the LCP database, the Patient Administration database (within the hospice) and a Bereavement database (within the hospital); the latter records whether or not the patient’s care was supported by the LCP and the resuscitation decision made by the patients’ responsible medical team. Manual checking of hospice case records and hospital bereavement records (stating cause of death on the death certificates) was undertaken to exclude sudden or unexpected deaths (Supplementary Figure 1) by the primary researcher (CM), and any uncertainties were discussed with a second researcher (JE).
Sample size was calculated using a previous post-bereavement study with ‘Views Of Informal Carers – Evaluation of Services’ (VOICES) questionnaire, which showed that 97% bereaved relatives perceived that their family member was treated with dignity ‘always’ or ‘most of the time’ in the hospice, compared with 70% for those in the hospital (Addington-Hall and O’Callaghan, 2009). We hypothesised that 95% of relatives would perceive that patients were treated with dignity in the hospice and 80% in the hospital. Using 5% significance level and 90% power, a sample size of ∼100 relatives was needed from each setting (hospice and hospital). By estimating a response rate of 40%, the total sample size required was at least 500 participants.
An information pack including the questionnaire, ‘Evaluating Care and Health Outcomes – for the Dying’ (ECHO-D) was sent out to 778 next-of-kins during 2006, at least 3 months following the bereavement. ECHO-D consists of 91 items, was developed from the goals of the LCP document, the existing post-bereavement surveys (including VOICES) and aspects of a ‘good death’ determined from the literature, and has been shown to be valid and reliable (Mayland, 2010; Mayland et al, 2012b). Reminder letters were sent out 4 weeks after the first mailing to non-respondents. Ethical approval was obtained from Liverpool (Adult) Ethics Committee (05/Q1505/126).
Data were analysed using SPSS version 16 and Statistical Analysis System (SAS) version 9.2 (University of Liverpool, Liverpool, UK). Comparisons of demographic data used χ2 tests, independent sample t-testing and Mann–Whitney U-testing. Comparisons between questionnaire responses used the Pearson’s χ2 statistic with 95% confidence intervals. For questions with ordinal response options, the Cochran–Mantel–Haenszel test was conducted using standardized mid-rank scores. Forced entry logistic regression was conducted to determine whether any demographic differences independently predicted responses to two key outcome measures: whether the patient was treated with dignity and respect, and whether the family was adequately supported.
Results
Of the 778 eligible to participate patients, 52 were excluded (next-of-kin had either died (n=3) or moved house (n=49) with no forwarding contact details). This left 726 potential participants, of whom 255 agreed to participate (35.1% response rate). Response rate was higher for the hospice next-of-kin compared with the hospital group (40.5% (109 of 269) vs 31.9% (146 of 457) χ2 5.46, P=0.02). An additional 141 (18.1%) returned their response forms, but declined participation, citing ‘emotional distress’ as the most common reason. Non-participants had a higher proportion of ‘other (for example, unknown primary)’ as the patient’s primary site of cancer compared with participants (n=128 (27.2%) vs n=42 (16.5%), χ2 10.57, P<0.001) (Supplementary Table 6). All patients who died an ‘expected death’ in the hospice were cared for by the LCP, with the others (n=73) having a more acute decline due to complications from their illness or being unable to retrieve case notes to clarify details. Within the hospital, for those who completed the ECHO-D questionnaire, 78 (53.4%) deceased patients had their care supported by the LCP (‘Hospital with LCP’ group) and 68 (46.6%) did not (‘Hospital without LCP’ group).
For participants, demographic details of deceased patients and their next-of-kin were compared (Table 1 and Supplementary Table 7). Deceased hospice patients, compared with hospital patients, were younger (68.5 vs 72.3 years, P=0.02), more likely to be female (57.8% vs 45.9%, P=0.05) and more likely to have breast cancer (12.8% vs 3.4%, P=0.005). Deceased ‘Hospital with LCP’ patients, compared with deceased ‘Hospital without LCP’ patients (Table 1), were older (74.6 vs 69.6 years, P=0.02) and more likely to have had hospital specialist palliative care team (HSPCT) involvement (44.9% vs 28.4%, P=0.04). The median time since bereavement was significantly shorter for the ‘Hospital with LCP’ participants (276.0 days) compared with ‘Hospital without LCP’ participants (415.5 days) (U 1628.5, P<0.0001).
Symptom control
With the exception of retained respiratory tract secretions, the ‘Hospital without LCP’ participants reported the highest symptom burden for their next-of-kin (Table 2). Hospice participants were most likely to be satisfied and the ‘Hospital without LCP’ participants least likely to be satisfied with the level of symptom control (Table 2). The level of satisfaction for ‘Hospital with LCP’ participants’ was between these two levels. For example, seventy-eight (72.2%) hospice participants responded that doctors and nurses had done enough to relieve the pain ‘all of the time’ compared with 46 (59.0%) ‘Hospital with LCP’ participants and 23 (33.8%) ‘Hospital without LCP’ participants (P<0.0001). Similar differences were seen for the control of restlessness and breathlessness.
Communication
Responses indicated that more open discussion about the provision and withdrawal of fluids in both health-care settings was needed, but especially in the acute hospital (Hospice n=20, 18.3%, ‘Hospital with LCP’ n=33, 42.3%, ‘Hospital without LCP’ n=33, 48.5%, p=0.003) (Table 3). Discussions informing participants that their family member was likely to die occurred on a similar frequency in both health-care settings (Hospice n=83, 76.9%, ‘Hospital with LCP’ n=61, 78.2%, ‘Hospital without LCP’ n=46, 67.6%; P=NS) and generally were of good quality. More hospice participants (n=44, 40.4%) reported conversations with health-care professionals about what to expect when their loved one died compared with the ‘Hospital with LCP’ (n=22, 28.8%) and ‘Hospital without LCP’ (n=11, 16.2%) participants (P=0.002).
Key outcomes – dignity and respect, and family support
Univariate analysis showed that the only variable associated with patients ‘always’ being treated with dignity and respect was when they received hospice care (OR 8.46, P<0.0001) (Table 4). Similarly, participants perceived that they were adequately supported when care was provided by the hospice (OR 7.18, P<0.0001) (Table 5). Participants within the hospital perceived that they were adequately supported when care was supported by the LCP (P=0.04) and when the HSPCT were involved (P=0.04), although multivariate analysis showed that neither was an independent predictor (LCP P=0.08; HSPCT P=0.09) (Supplementary Table 8).
Discussion
To our knowledge, this is the first post-bereavement study within the United Kingdom that explores the impact of the LCP on the quality of care for dying cancer patients from the user’s perspective. Overall, hospice participants reported the highest quality of care for dying patients and their families, and the ‘Hospital without LCP’ participants reported the lowest quality of care. The quality of care reported by the ‘Hospital with LCP’ participants was reported as being in between these two levels. The overall aim and philosophy of the LCP is to transfer the principles and ‘best practice’ of hospice care into the acute hospital setting. This study demonstrates that for some aspects of care, such as symptom control, this cultural shift appears to be occurring, whereas for others, including aspects of communication, more is required to be done to try to attain the hospice standard of care.
The main limitation of the study is the response rate of 35.1%, which is comparatively low and lower than the 40% response rate we had estimated. This can lead to the introduction of non-response bias and limit the generalisability of the findings to the whole population. Post-bereavement research studies represent a difficult and sensitive area of work, and this is likely to be the main and most important reason for the low response rate. There was almost a 10% difference in the response rate between the two health-care settings, with a greater response from hospice participants. This may be related to the differing settings for the two institutions, that is, urban area for acute hospital and more affluent ‘conservation’ area for the hospice; a higher degree of altruism towards the hospice (which is a recognised charity); or that those who had a more positive experience were more motivated to provide feedback about the care. Our response rate is comparable with two other recent UK studies using post-bereavement questionnaires (NHS Lothian, 2007; Young et al, 2008). The response rate, however, is lower than the recent UK National VOICES Bereavement Survey (response rate of 45.7%) (Department of Health, 2012b), although this survey had three mail-outs, a practice which was not permitted by our ethical committee. Overall, our participants were similar to our non-participant group, with the exception that non-participants were more likely to have ‘other (for example, unknown primary)’ as their primary site of cancer. We do not have, however, information on other demographic factors known to influence response rates, therefore, caution is needed about the generalisability of our results. The second limitation of this study is the difficulty in clarifying the sole extent to which the LCP influenced perceptions and the role of other factors, such as communication skills teaching and the HSPCT. In part, this relates to only have single study sites for the hospice and hospital, and potentially to our sample size. As most of our analysis compares three groups, our study may have been underpowered (ideally we should have obtained 100 participants for each group). The ‘Hospital with LCP’ participants more frequently had involvement from the HSPCT, which is likely to have had a positive impact on the perceptions of care. A previous systematic review assessing the effect of specialist palliative care teams (both hospital and community) showed benefit in terms of satisfaction with care and symptom control (Hearn and Higginson, 1998). Additionally, a further review specifically of hospital teams showed small positive benefits, although limitations in the study design affected assessment (Higginson et al, 2002). The HSPCT within our study hospital was established in 1994, limiting the potential time-lag benefit, but clarifying the extent of the involvement of the HSPCT on both hospital groups, would be useful. Our choice of study groups would also influence this and may have introduced selection bias. Ideally, we would have liked to also have had a ‘Hospice without LCP’ group and be certain that the ‘Hospital without LCP’ group was a representative group, that is, that the death was expected and care could have, and potentially should have, been supported by the LCP. The third limitation relates to the fact that the bereaved relatives’ views cannot be assumed to be the same as that of the deceased patient. Post-bereavement studies, however, have certain advantages: they can reflect care for all those who have died rather than just those who are well enough to participate; and they provide additional information about the participants’ own experience, as well as provide ‘proxy’ information about patient care (Fowler et al, 1999).
One of the strengths of this study is the specific detail obtained, thus providing a comprehensive picture about care for the dying cancer patients and identifying the areas that require improvement. Although aspects of communication were of a similar quality in both health-care settings, there was still unmet need for information about the provision and withdrawal of fluids and what to expect when someone dies, with the greatest degree of unmet need seen for the ‘Hospital without LCP’ participants. Adequate control of distressing symptoms in the last days of life is a key component of good care. Hospice and ‘Hospital with LCP’ participants reported very similar symptom prevalence and with the exception of retained respiratory tract secretions, reported a lower symptom burden compared with the ‘Hospital without LCP’ participants. These findings may be related to a genuine difference in symptom prevalence, with patients from the ‘Hospital without LCP’ group having more complex symptoms. Alternatively, this could indicate that the LCP is encouraging a more intensive and pro-active approach to symptom control, which would be in keeping with the findings from a Scottish study undertaken in eight care homes using the LCP (Hockley et al, 2005), and a North American study that used the ‘Palliative Care for Advanced Disease’ integrated pathway in the last days of life (Bookbinder et al, 2005). A further consideration is the influence of the shorter time since bereavement for the ‘Hospital with LCP’ participants. This was mainly related to difficulties retrieving accurate next-of-kin details for the ‘Hospital without LCP’ group (more likely to be missing or incomplete), which required retrieval of the medical case notes. Perceptions about quality of care over time can change, with pain and depression tending to be reported as less frequent and severe as time passes (McPherson and Addington-Hall, 2004). If this principle was applied to our study, it would suggest an underestimation of the symptom severity within the ‘Hospital without LCP’ group, and that the differences may have been actually greater than our reported findings.
Further clarification about the role of other external influencing factors is merited by assessing quality of care for the dying in the institutions that use an integrated care pathway with comparable ones, which do not. Since this study has been conducted, version 12 of the LCP has been launched (Ellershaw and Wilkinson, 2011b), with more detailed documentation about the decisions relating to clinically assisted hydration and nutrition. Further evaluation of the impact of these changes is required, ideally by using a before- and after-study approach. Additionally, in order to clarify whether it is simply the bereaved relatives’ perceptions that are altered or whether there is a significant change in clinical practice when the LCP is used to support care, an observational study would be beneficial. Although our results suggest that there has been some improvement in care for dying cancer patients within the hospital when the LCP is used, further progress is needed to be able to deliver care, which is more comparable with the hospice standard. Ongoing review and updating of the LCP as well as educational initiatives focusing on pertinent end-of-life discussions would be practical ways to facilitate this, and to hopefully further improve the experience of the dying patients and their families in the hospital sector.
