Abstract

Morgan J (2010) How to improve services for dying patients in critical care: adapting protocols. Nursing Times; 106: 4, early online publication.

This article outlines a project to improve end of life care for those who are critically ill, by adapting and implementing a national protocol specially developed for the intensive care unit. The rollout of the pathway is discussed along with an audit which found the trajectory towards death following withdrawal of treatment can be swiftThe extent of documentation is therefore an important consideration to ensure nurses can balance patients’ needs with those of grieving relatives while ensuring bereavement care is accurately documented.

Practice points

  • While policy has been a key driver for this project, on its own it is not enough to ensure success. The following are vital: a clear purpose and objective; preparation and planning before implementation; and reflection and revision.
  • Projects like this enable those involved to gain enormous satisfaction, which regenerates clinical practice and creates expert practitioners.

 

Introduction

We identified a need to improve care of dying patients in critical care (see Background box).

We decided that following the Liverpool Care Pathway (LCP) for the dying patient would be beneficial. Already familiar with Integrated Care Pathways (ICP), the LCP was the obvious vehicle for change.

We decided to adapt the generic LCP to suit our purpose and patient group: those who are critically ill. This coincided with work by John Ellershaw and the Liverpool Hospital palliative care team who were about to publish the LCP for ICU. As a result, we adopted this national pathway for ICU with minor amendments, while keeping the original format.

The process

We set up a focus group to ensure we worked with clinicians during the project’s design and implementation. The group comprised 10 nurses of different grades and its aim was to maximise dissemination of the LCP across the unit.

We registered with the Marie Curie Palliative Care Institute ICU Action Research Project, which provided support, a template for the LCP in ICU and use of the LCP 10 steps continuous quality improvement programme (Marie Curie Palliative Care Institute Liverpool, 2009; 2007). This programme brought with it resources and reliability beyond the scope of a small trust project, making implementation cost effective in terms of time, expertise and people.

The transferability of the quality improvement programme to the critical care unit needed sensible application, as the resources trusts can offer dying patients varies according to organisation and staff. It is important to be realistic about what can and cannot be changed. Our palliative care service is fairly minimal; extra work would be burdensome. A solution was to create links with the local hospice, which could also prove to be useful when rapid discharge from ICU becomes part of end of life care.

Preparing for change

Being responsible for planning and implementing change in practice/behaviour involves bringing about a major cultural shift. As end of life care in critical care is possibly more varied and complex than other areas of the hospital, this will take time, from both a personal and professional perspective.

It is imperative to have a thorough understanding of the legal and ethical issues involved. In the UK, the legal practice of withholding and withdrawing treatment is determined by doctors, although usually carried out after a consensual decision making process involving other professionals and family members. Moreover, we now live and work in a multicultural and ethnically diverse society, which requires greater understanding and sensitivity.

It was therefore necessary to conduct a literature review to understand current practice surrounding end of life care in critical care. This review reinforced the notion that deep seated beliefs affect care of dying people (Morgan, 2008).

To raise awareness and promote the project, regular informal meetings gave nurses and other healthcare professionals the opportunity to:

  • Meet the end of life care coordinator for the PCT;
  • Learn how to complete the LCP;
  • Understand variations in care;
  • Reflect on care of dying people.

This process empowered clinicians and enabled them to disseminate knowledge to other critical care staff. Subsequent education and support was delegated to key members of staff.

The focus group was keen to offer bereavement care and felt the synergy between the LCP and a bereavement service for ICU was inescapable. This provided the opportunity to capitalise on earlier work, which had identified the need for ICU bereavement care. As two different strands of care were being implemented at the same time, we planned a staggered roll out.

Launching the care pathway

Documentation for the LCP ICU was approved and the launch date was set for early autumn in 2007. This allowed enough time to gather data for a base review. It was important to examine current practice before implementation to measure change after the launch. Data was collected on 20 level 3 patients (those requiring advanced respiratory support, as defined by the Intensive Care Society, 2002), following withdrawal of treatment in critical care.

As the trust had already signed up to the national end of life care programme (see www.endoflifecare.nhs.uk), gaining permission for the audit was a formality.

Data collection

Computerised analysis and feedback was provided by the Marie Curie Palliative Care Institute Liverpool and contributed to their national research project.

Initial observations reinforced the necessity of adhering to legal and professional requirements, as some documentation was missing (Figs 1 and 2). In addition, GPs are rarely made aware of patients who are dying, but routinely notified after death (goal 13).

Under these circumstances the pathway for ICU acts as a prompt. A cultural shift in end of life care is evident when ICU doctors involve GPs in the decision making process before withholding or withdrawing treatment.

Aspects of care thought to be embedded in practice, for example, providing explanations and information booklets after death for relatives were, according to the documentation, carried out in part.

When documentation is poor it is difficult to ascertain if, or indeed how, the needs of dying people and their families have been met. Completing documentation was a key teaching point in the education programme.

The base review also produced some incidental findings. For example, compared with Wunsch et al (2005), who found the median time to death after withdrawal of treatment was 2.4 hours, our time was longer. This was surprising, but may not be a reliable representation of events due to the snapshot sample and variation in participants. Also, it was apparent that decision making often occurred between 10.30am and noon, with death following some 45 minutes to six hours later. This reinforces the idea that bedside nurses have absolute responsibility for the LCP ICU during their shift, as 12 hour shifts mean they are likely to see the care episode through from decision making to withdrawal of treatment to death. This was another point to bear in mind during rollout and the education programme.

Implementation

The pathway’s rollout was gradual and based on an average of two deaths a week, remembering that not all deaths in critical care follow withdrawal of treatment.

After training, there was a “hands on” phase where key nurses were the first to use or support staff using the pathway. This was because findings from the base review supported a step by step programme. However, compliance increased as nurses appreciated the authority to stop inappropriate treatments, which reflected findings by Lhussier et al (2007). Also, once the decision had been made to withdraw treatment, the pathway enabled a course of actions, which would have otherwise been ambiguous and subject to individual variation. Furthermore, as Lhussier et al (2007) said, the end of life integrated care pathway used by trusts in the north of England promoted an enhanced openness between families and professionals.

Continued educational input ensures staff understand not only the documentation but also wider issues such as communication, symptom relief, spiritual and cultural awareness. As part of the educational programme, feedback was considered important. A number of methods were chosen, including: one to one, group and critical care meetings; the intranet; publications; and an inter-hospital multidisciplinary team study day.

A more formal means of reflection involved a post-pathway analysis: 20 pathways were audited and submitted to the LCP Central Team UK for computer analysis and feedback. Improvements were expected and some were found, but these were not the issue. Strangely, bereavement care that was accurately documented pre-implementation was comprehensively absent after it. This was attributed to the size of the document versus the speed of death, as the trajectory towards death following withdrawal of treatment can be swift and extremely demanding for nurses, who must balance patients’ needs with those of grieving relatives and extensive documentation. Slower and “traditional” palliative care deaths afford more time for patients, relatives and documentation. The response was to renew the educational input, reduce the number of pages and make the document more concise. These changes were appreciated and await audit before any further modification.

Conclusion

The LCP for ICU has facilitated quality care during the intense and final hours of life following withdrawal of treatment. Furthermore, the pathway is acknowledged during decision making, which helps to clarify treatment plans and goals for critically ill patients.

 

Background

  • A range of major government initiatives have highlighted the need to improve the care of dying patients, including the DH’s (2008) end of life care strategy and report on this (DH, 2009).
  • We used the Marie Curie Palliative Care Institute Liverpool’s (2007a) Liverpool Care Pathway (LCP) for the dying patient within the intensive care unit (ICU) version 11 in drawing up our care pathway.
