This is a plain English summary of an original research article
A multicomponent support intervention for family members of patients in intensive care didn’t reduce their anxiety, depression or distress around the overall experience. However, it increased satisfaction with the quality of staff communication and delivery of care.
Family members of critically unwell patients on intensive care often need to be involved in care decisions. Yet they may feel unsupported and bewildered in the process. This intervention, delivered in five US intensive care units, involved training nurses in advanced communication skills and setting up regular meetings between the family and healthcare team. In addition to small improvements in family’s perceptions around care, the intervention was also associated with a shorter stay in intensive care for patients who died. The intervention cost on average $170 US per patient.
The findings support UK guideline recommendations for shared decision-making between the patient (where possible), those important to them and the multi-professional care team.
Why was this study needed?
In England, in 2015-16 there were 271,079 records of adult critical care, 6% (11,045) of which were in intensive care. The End of Life Care Audit for the same period showed that 13% of people who died in hospital did so in critical care. For almost half of patients who died, there was no indication that staff had asked about the needs of those closest to them.
The families of severely unwell people may feel they have insufficient opportunity to discuss their loved one’s prognosis, treatment options, preferences and values. This can contribute to distress or lead to care that may be against patient wishes. This includes difficult decisions, such as when to withdraw treatment. A previous Signal on people dying in intensive care demonstrated that families need to receive personalised communication and be involved in the dying process.
This study evaluated whether an intervention to improve the quality of shared decision-making and family-staff communication could benefit both patients and families.
What did this study do?
The PARTNER randomised controlled trial was conducted in five intensive care units in Pittsburgh, US, with diverse sociodemographics, hospital settings and staffing structure. It involved the family members of 1,420 patients who had a high risk of dying or severe long-term disability and were unable to make decisions themselves.
In the intervention group, nurses received advanced communication skills training, centring upon supporting families of seriously ill patients. Trained nurses met with families daily and arranged doctor-family meetings at least weekly. The control group received usual care. Although the intervention cost on average $170 US, the cost-effectiveness of the intervention was not reported.
Six months after hospital discharge or death, study personnel who were unaware of group assignment conducted telephone interviews with 73% of family decision-makers.
The intervention group included more female patients who were slightly older, more acutely unwell and had more additional illness. The analysis adjusted for these differences.
What did it find?
- At six months, there was no difference between groups in the main study outcome of family decision-makers’ scores on the Hospital Anxiety and Depression Scale. This has a score range 0-42 where higher scores indicate more symptoms. Scores were 11.7 in the intervention group and 12.0 in the usual care group (difference -0.34, 95% confidence interval [CI] -1.67 to +0.99).
- Families in the intervention group rated the quality of clinician-family communication as about 6 percentage points better, a small improvement. Their average score was 69.1 on the 100-point Quality of Communication scale, where higher scores relate to better communication, compared with 62.7 in the usual care group (difference 6.39, 95% CI 2.57 to 10.20).
- The intervention group also gave better ratings on the Patient Perception of Patient Centeredness scale, which had been adapted for use by surrogates. Scores were 1.7 out of 4 compared with 1.8 in the usual care group (difference -0.15, 95% CI -0.26 to -0.04) where lower scores indicate better patient- and family-centred care.
- Patients whose relatives received the family support intervention had slightly shorter stays in intensive care (6.7 vs 7.4 days; incidence rate ratio [IRR] 0.90, 95% CI 0.81 to 1.00) and in hospital overall (10.4 vs 13.5 days; IRR 0.77, 95% CI 0.69 to 0.87). Further analysis revealed the effect was mediated by a shortened stay in intensive care among patients who died (4.4 vs 6.8 days; IRR 0.64, 95% CI 0.52 to 0.78.) There was no difference in length of stay for patients who survived to hospital discharge.
- The in-hospital mortality rate was slightly higher for patients in the intervention group (36.0% vs 28.5% in the usual care group; odds ratio 1.43, 95% CI 1.10 to 1.87). However, there was no difference between groups in mortality by six months.
What does current guidance say on this issue?
UK Guidelines for the provision of intensive care services (2015) include recommendations for communicating with relatives and supporting shared decision-making. This includes providing psychological support in recognition that critical care can be associated with significant stress and traumatic reactions.
The NICE guideline Care of dying adults (2015) provides recommendations around recognition of the last days of life, communication, shared decision-making and symptom control, which consistently emphasise the need to discuss with both the dying person and those important to them. It’s recommended that a named healthcare professional is responsible for encouraging shared decision-making and ensuring that care plans are understood by family members.
In this country, much of the work to compare quality and outcomes of intensive care centres is carried through the Intensive Care National Audit and Research Centre.
What are the implications?
Although increased family support didn’t alter the overall distress of having a relative in intensive care, improving satisfaction with the quality of care and communication seem equally important outcomes. Increased support may also lead to improved recognition of end of life and transition to palliative care.
The findings support national recommendations, though there may be variation in UK hospitals in how shared decision-making is facilitated. Intensive care systems in the US are comparable to that in this country, so these findings are relevant here. However there are some small differences in staffing and care processes, so the cost of the intervention in the UK may be different.
The Psychosocial Assessment and Communication Evaluation tool has been developed as part of an NIHR-funded study to improve communication with families in intensive care.
