Supervision required for staff in specialist mental health settings

Review question

What are the views and preferences of staff in specialist mental health settings about what supervision is required for staff in specialist mental health settings who assess and treat people who have self-harmed?

Introduction

Staff who work with people who self-harm are likely to experience a range of conflicting feelings about their work, and self-harm may have considerable emotional impact on clinicians. It is important that organisations support and maintain the ability of clinicians to work with people who self-harm in a compassionate and respectful way at all times. It can be necessary to intervene to prevent further harm and to ensure the person’s safety, but at the same time, staff need to respect people’s autonomy. This can be a difficult balance at times and requires team and organisational support for individual clinical decision-making. The objective of this review is to identify the views and preferences of staff in specialist mental health settings about the supervision that is required for staff in specialist mental health settings who assess and treat people who have self-harmed.

Methods and process

This evidence review was developed using the methods and process described in Developing NICE guidelines: the manual. Methods specific to this review question are described in the review protocol in appendix A and the methods document (supplementary document 1).

Declarations of interest were recorded according to NICE’s conflicts of interest policy.

Qualitative evidence

Included studies

Eleven qualitative studies reported in 12 articles were included for this review. Two articles reported results from the same study (Hagen 2017a, Hagen 2017b).

The included studies are summarised in Table 2.

The studies were carried out in 5 different countries: 3 studies in the UK (Awenat 2017, Littlewood 2019, MacDonald 2021); 1 study in Australia (Kelada 2017); 2 studies in Canada (Christianson 2008, de Stefano 2012); 2 studies in Norway (Berg 2020; Hagen 2017a, Hagen 2017b); 3 studies in the USA (Hoffman 2013, Knox 2006, Wilstrand 2007).

Studies exploring the views and preferences of specialist mental health staff regardless of setting were included in this review. At the time of agreeing the protocol, the objective of the review was to identify the views and preferences of staff in specialist mental health settings about what supervision is required for staff in specialist mental health settings who assess and treat people who have self-harmed. However, the committee later agreed the best way to summarise evidence regarding staff supervision would be to split evidence according to the specialty of the staff rather than the setting, because some specialist staff may work in non-specialist settings, and it would be inappropriate to suggest they should have the same views and preferences on supervision as non-specialist staff. Therefore, this review summarised evidence regarding supervision required by specialist mental health staff, while another review was conducted to summarise evidence regarding skills required by non-specialist staff (see Evidence Report S).

The studies included specialist staff working in the following settings: 3 studies in educational settings, including schools and university counselling services (Christianson 2008, de Stefano 2012, Kelada 2017); 1 study in an emergency department (MacDonald 2021); 4 studies in inpatient psychiatric wards (Awenat 2017, Berg 2020, Hagen 2017a, Hagen 2017b, Wilstrand 2007); 2 studies in varied mental health care settings (Knox 2006, Littlewood 2019).

The committee’s discussion and interpretation of the evidence

The outcomes that matter most

The aim of this review question was to identify what supervision is required for staff in specialist mental health settings who assess and treat people who have self-harmed. The committee agreed that any differentiation between required supervision would likely be due to staff specialty rather than setting specialty, because specialist staff may work in non-specialist settings. As a result, the views members of specialist staff who assess and treat people who have self-harmed or their supervisors were considered the most important for this question. The committee suggested potential themes which may have arisen from the evidence such as respectful behaviour, compassion, understanding function of behaviour, communication style, frequency, support to make decisions and skilled supervision but did not want to constrain the question; therefore, any views and preferences about specialist staff supervision regarded as useful/ not useful or important/ not important by the population were included.

The quality of the evidence

When assessed using GRADE CERQual methodology the evidence ranged in quality from very low to moderate quality, with the majority of the evidence low quality. The recommendations were drafted mostly based on the evidence but in some parts supplemented accordingly with the committee’s own expertise where the evidence was low or very low quality.

In some cases, the evidence was downgraded due to poor applicability where the themes were not based on any research from a UK context, or where the study population were specialist staff who worked with people with suicidal behaviour (which did not specify whether the patients had self-harmed). It was noted where studies were conducted in non-specialist settings, but studies were not downgraded for applicability solely due to this. Some downgrading for adequacy occurred when the richness or quantity of the data was low. Other issues resulting in downgrading were methodological limitations, mainly inadequate explanation of the recruitment approach, concerns about potential influence of researchers on study findings, a lack of researcher reflexivity and a lack of acknowledgement of data saturation, that may have had an impact on the findings.

Benefits and harms

The recommendations about supervision for staff who work with people who have self-harmed were based on the evidence from both specialist and non-specialist staff (see evidence review S) as there was a significant overlap between the kind of supervision both specialist mental health and non-specialist professionals wanted when working with people who have self-harmed. Many of the identified themes in this review were similar to those identified in the non-specialist staff review, with some differences between themes relating to the level of detail or specific needs of non-specialist staff.

There was evidence from both specialist and non-specialist staff that all professionals working with people who self-harm valued different types of supervision for specific purposes, including regular formal supervision, decision-making support during an episode of self-harm to emotional support, and skill development after an episode of self-harm. The committee were concerned that self-harm specific supervision is not currently routinely incorporated into formal supervision practices, despite the prevalence of self-harm and the unique challenges and concerns associated with providing care and support for someone who has self-harmed. The committee had some concerns with the applicability of the findings as most evidence was from staff working with people with suicidal behaviour who had not necessarily previously self-harmed, however, based on their experience and expertise they felt comfortable in applying this evidence to staff working with people who have self-harmed, and agreed to make recommendations on both regular formal self-harm specific supervision and accessible ‘on-the-job’ self-harm specific support.

The committee discussed the theme ‘frequency of supervision and communication style’ and agreed that all staff working with people who self-harm should be able to access formal supervision that is regular, high-quality, structured, and distinct from general clinical supervision and case load management. Based on the evidence and their own experience, the committee made a recommendation that formal supervision should be provided by a senior member of staff with the relevant skills, training and experience, to all staff who work with people who self-harm. For non-specialist staff, the sub-theme ‘supervision culture’ showed that often, formal supervision was not embedded in routine practice and was more of an exception than a rule, provided only in times of crisis. However, there was limited evidence, in terms of quantity, to support making a recommendation about how regular formal supervision should be for staff who work with people who self-harm. The committee agreed the regularity of formal supervision would therefore be dependant on setting-specific factors, such as rates of self-harm, acuteness of self-harm, and available resources. They acknowledged there was insufficient evidence, in terms of quantity, to further specify the mode of supervision, for example internal versus external supervision or group versus individual supervision. The committee discussed the sub-theme ‘sensitivity and empathetic communication’ identified in the specialist staff review and, while they acknowledged the importance of communication style, they agreed that it was not specific to self-harm supervision and did not want to make recommendations on general principles of supervision. Therefore, the committee agreed that all staff should have the opportunity to receive regular formal supervision as needed, but could not be more specific about how this should be delivered based on the strength of the available evidence.

The committee discussed the evidence from the theme ‘emotional support’ which showed some staff felt that episodes of self-harm and patient suicides could impact their ability to deliver compassionate care. The committee agreed it was important that the sensitive nature of self-harm was acknowledged during supervision to enable the provision of support, but noted that it was unhelpful and inaccurate to imply that people who have self-harmed are at fault. The committee also agreed that the support needs of staff should not affect the quality of support and care provided to the person who has self-harmed. Therefore, the committee agreed that the delivery of compassionate care should also be promoted as an aspect of supervision, to ensure the support needs of both people who have self-harmed and the staff who work with them are continuously met.

The theme ‘skill development’ captured evidence of the value both specialist and non-specialist staff placed on having time for feedback and reflective practice following an episode of self-harm. There was evidence that staff viewed reflective practice as an invaluable means to learn from their experiences or the experiences of others and improve their clinical practice, however, there was evidence that often this was not prioritised due to time and resource constraints, especially for non-specialist staff. The committee agreed that in their experience, reflective practice was overlooked or rushed and agreed that it should be prioritised within formal supervision for staff who work with people who self-harm. Based on this evidence and their experience, the committee made a recommendation specifying that ongoing skill development and reflective practice should be a key component of formal self-harm supervision for both specialist and non-specialist staff as it promoted confidence and competence.

In addition to formal supervision, the theme ‘support to make decisions’ described how staff valued having accessible and immediate support from senior colleagues when caring for people who self-harm as this acted to promote confidence in difficult situations; this was particularly important for non-specialist staff who valued informal interactions with senior staff to confirm care decisions and feel reassured in their decisions. For specialist staff, uncertainties around responsibility and liability were noted, with staff describing the unclear lines of responsibility in difficult situations where duty of care conflicted with patient autonomy. The committee were concerned that anxiety around fear of litigation in difficult situations could impact quality of care and agreed that supervision support for staff working with people who self-harm should reinforce lines of responsibility and provide advice to facilitate staff in making the most appropriate decisions.

With respect to the theme ‘emotional support’, there was evidence that staff valued receiving professional emotional support following an episode of self-harm or suicide because it helped them to process their experience and normalise their feelings and reactions. However, it was reported that often formal emotional support was not provided, with a particular lack of support noted for specialist staff in educational settings. The committee agreed that, in their experience, support services were not routinely available for specialist staff working in non-specialist settings, such as schools, however, they highlighted that access to support in these situations was improving with the expansion of CAMHS services in schools. There was inadequate evidence, in terms of quantity, to determine whether emotional support should be provided by a clinical supervisor or whether it should be accessed externally, however the committee agreed that in their experience, it was often more appropriate for the member of staff to speak to someone removed from the situation. The committee agreed formal supervision should ensure that all staff working with people who have self-harmed have access to emotional support or emotional support services as needed.

Cost effectiveness and resource use

The committee noted that no relevant published economic evaluations had been identified in the literature review. In addition, the development of a bespoke economic model in this area of the guideline was not prioritised as other areas were considered as higher priorities for primary economic analysis. When drafting the recommendations, the committee agreed that staff in specialist mental health settings working with people who self-harm should receive regular, high-quality formal supervision, the regularity of which should be determined, among other factors, by available resources. The committee noted a likely increase in costs associated with providing staff in specialist mental health settings with formal supervision. However, they expressed the opinion that additional costs are likely to be offset by better health outcomes, by improving the care and quality of life of people who have self-harmed.

The committee discussed the cost implications of providing accessible emotional support or emotional support services to all staff who work with people who self-harm and concluded that in most clinical settings 24 hour support was already available so there would be minimal impact. For specialist staff working in non-clinical settings, such as educational settings, the committee discussed that support should already be available for pastoral care givers and the recommendations mirror the introduction of designated leads in mental health in schools.

Please note that the current search was undertaken with the search for review questions P (What are the views and preferences of staff in specialist mental health settings, people who have self-harmed and their family members/carers about what skills are required for staff in specialist mental health settings who assess and treat people who have self-harmed?), R (What are the views and preferences of staff in non-specialist mental health settings, people who have self-harmed and their family members/carers about what skills are required for staff in non-specialist mental health settings who assess and treat people who have self-harmed?), and S (What are the views and preferences of staff in non-specialist mental health settings about what supervision is required for staff in non-specialist mental health settings who assess and treat people who have self-harmed?), and the list of excluded studies below only lists the 77 studies that were excluded for all reviews in contrast to the 119 excluded studies specified in the PRISMA diagram. This is because routing used in EPPI-Reviewer to separate the results of review questions P-S (for which a combined search was performed) resulted in EPPI-Reviewer being unable to generate the excluded studies list in the usual format, with the excluded studies for review questions P-S separated. Please see the PRISMA diagram for details of the (119−77 =) 42 studies not listed in the excluded studies tables below, which are studies that met the inclusion criteria for review questions P, R and/ or S.
