Abstract

Aims and Method

To audit whether the introduction of a self-harm pathway and protocol increases the number of psychosocial assessments. All episodes of self-harm in a defined period during 2002 (n=335) and 2004 (n=390) were reviewed before and after the introduction of a self-harm pathway and protocol. Adherence to the protocol was also investigated.

Results

After the introduction of the self-harm pathway and protocol, the proportion of psychosocial assessments requested had risen from 57% (2002) to 85% (2004). The proportion of psychosocial assessments completed had risen from 47% to 70%. Over the 2 years, the overall number of self-harm presentations was reduced by 27%.

Clinical Implications

The introduction of a self-harm pathway and protocol through a self-harm steering group is feasible, was well accepted and increased the number of psychosocial assessments after self-harm. It may also contribute to a reduction in the number of overall presentations with self-harm to the accident and emergency department.

Self-harm is one of the most common presentations to general hospitals. There are over 140 000 estimated attendances at the accident and emergency (A&E) department each year as a result of self-harm (Reference Hawton, Fagg and SimkinHawton et al, 1997). The rates and treatment vary significantly across the UK (Reference Bennewith, Gunnel and PetersBennewith et al, 2004). One per cent of patients who self-harm will go on to kill themselves within a year (Reference Hawton and FaggHawton & Fagg, 1988). Repetition of self-harm is associated with an increased risk of suicide in both males and females (Zahl & Hawton, 2004), yet there are few large studies investigating the effectiveness of interventions. In a Cochrane Systematic Review, Hawton et al (Reference Hawton, Townsend and Arensman2000) showed that there are trends towards reduced repetition rates with problem-solving therapy and emergency contact cards, in addition to standard after-care. Single small trials showed significantly reduced rates of further self-harm for depot flupenthixol v. placebo in those repeatedly self-harming and for dialectical behavioural therapy v. standard after-care.

The National Standard Framework for Mental Health Service (standard seven) states the aim of reducing suicide rates by 20% by the year 2010 (Department of Health, 1999). A functioning self-harm service planning group, and the provision of a psychosocial assessment after self-harm, are part of the recommended strategy to manage self-harm in the UK (Royal College of Psychiatrists, 1994, 2004; Reference LeppingLepping, 2004). The existing literature supports the idea that relatively minor service changes, especially checklists, can significantly improve delivery and the recorded standard of care (Reference Dennis, Evans and WakefieldDennis et al, 2001). Furthermore, it was recently shown that psychosocial assessment reduces the repetition rates of self-harm by up to 50% (Reference Kapur, House and DodgsonKapur et al, 2002) but the provision of psychosocial assessment in many hospitals remains poor (Kapur et al, Reference Kapur, House and Creed1998, Reference Kapur, House and Creed1999). These observations are supported by further studies showing those who leave the A&E department after self-harm without an assessment are at greater risk of repetition of self-harm (Reference Hickey, Hawton and FaggHickey et al, 2001). It seems desirable, therefore, to ensure the optimal use of these assessments in A&E settings. To address this issue, we examined whether a self-harm pathway, developed by a local self-harm service planning group, could increase the number of psychosocial assessments.

Method

In 2002, we examined all self-harm presentations to Arrowe Park Hospital which serves urban as well as semi-urban areas around Liverpool, with large variation in levels of social deprivation. During an 8-week period, 335 adults over 16 years of age presented to the A&E department with self-harm. Of these 335, only 157 (47%) received a psychosocial assessment despite the existence of a local liaison psychiatry team consisting of medical and nursing staff. We therefore set up a local self-harm service planning group led by the specialist registrar in liaison psychiatry. This group met four times to discuss the difficulties faced by the A&E department and psychiatric services in responding to the assessment and management of self-harm in a coordinated way. These meetings allowed a mutual appreciation and understanding of the difficulties faced by both services. It was thus agreed to develop a common pathway to deal with self-harm based on the College recommendations and the Manchester triage system (Reference MacKway-JonesMackway-Jones, 1996). This included a self-harm protocol with clear allocation of responsibilities. More importantly, all participants in the planning group accepted ownership of the pathway and protocol feeling that their particular concerns had been addressed.

Accident and emergency triage nurses initially assessed patients to ascertain their willingness to wait for psychosocial assessment. This first appraisal was followed by an extended risk assessment using questions designed to measure immediate risk and whether the patient was known to mental health services. It was agreed that an A&E doctor would complete a medical examination and be responsible for completing an immediate risk assessment. Following any necessary physical treatment, the liaison psychiatry team would perform a specialist psychosocial assessment. A discharge summary page would be completed by A&E or ward staff and faxed to the general practitioner (GP) and community mental health team where appropriate. The format for the pathway was similar to that of other pathways currently in use in the hospital and it was hoped this familiarity would further increase acceptance among staff.

Once the format for the pathway was agreed, consideration was given to potential problems, such as patients absconding or refusing assessment. In such cases telephone helpline numbers would be provided to the patient and the GP would be informed by faxing a copy of the pathway to the surgery. Consideration was also given to patients who required time to recover from overdose as well as any co-ingestants such as alcohol. It was agreed that patients who were not admitted to a medical or surgical ward would be allowed to recover in the observation ward adjoining the A&E department.

In order to promote and facilitate the use of the pathway, training needs were identified and a programme of training formulated. Accident and emergency doctors received training as part of their teaching programme and it was agreed this would continue with the liaison psychiatry team providing training. To raise awareness of the policy and pathway, all hospital staff were invited to a high profile launch day. The pathway was introduced in June 2003. Over a 3-month period from June to August 2004 we again examined all self-harm presentations to Arrowe Park Hospital using the same procedures as in 2002. Collected data included age, gender, day of admission, time of admission, type of self-harm, evidence of psychosocial assessments being requested, whether undertaken, and by whom, as well as the outcome of the assessments, including admission to other hospital units. We asked for a previous history of self-harm, whether patients were currently in receipt of mental health services and who provided follow-up. In 2002, data from all age-groups were recorded but data for those under 16 were later removed from the analysis. In 2004, only data from patients who were 16 years or older on the day of presentation were examined.

Results

In June and July 2002, there were 335 presentations of self-harm at Arrowe Park Hospital A&E department; all episodes were traceable. The same months were examined in 2004 plus one additional month (August). In 2004, 390 episodes of self-harm were recorded over 3 months, 261 of these in the first 2 months. In 2004, two presentations were excluded because we were unable to find the relevant notes. The proportion of psychosocial assessments requested after the introduction of the self-harm pathway had risen from 57% (2002) to 85% (2004). The completed psychosocial assessments had risen from 47% to 70%.

Reasons why psychosocial assessments were not requested included patients leaving the department before seeing a doctor, refusing an assessment, self-discharging, or not being medically fit. All these reasons were rare; only 17 patients in 2002 and 25 patients in 2004 left the department or self-discharged before being seen for a psychosocial assessment. Only eight patients in 2002 and nine patients in 2004 refused a psychosocial assessment; the vast majority were willing to stay for assessment. In 2 years, the overall number of self-harm presentations decreased from 355 to 261, with the months of June and July alone showing a reduction of 27% (Table 1). The reference group for 2002 excluded all episodes of pure alcohol or illegal drug self-harm.

The proportion of assessments performed within 24 h rose sharply, and most patients were seen by a mental health liaison nurse or a psychiatric senior house officer in 2004 (92% v. 59% in 2002). In 2002, 23 patients left or discharged themselves before they were seen for a psychosocial assessment but after it had been requested. Only one refused assessment after agreeing to a request. In 2004, 35 left before the assessment was performed, 3 refused and 6 were not medically fit even 24 h after they first presented. The remaining patients had other explanations for non-attendance. In 2004, 77% of patients who presented were admitted. Psychiatric admissions were rare. In 2004, the proportion of patients with a history of self-harm had decreased by 10% (Table 1).

In December 2003, we audited how well our self-harm pathways were being followed. We applied very strict criteria for completion of forms and found that at triage 81% of all forms were fully completed with 6% mostly completed; 71% of all forms for psychosocial assessment were fully completed and 10% mostly completed (Table 2). This suggests that the pathway was very well accepted overall.

Discussion

The introduction of a local self-harm pathway and protocol that started at the time of triage in the A&E department and ended when the patient was discharged, significantly increased the number of psychosocial assessments. This audit has shown it is feasible to develop a self-harm pathway through self-harm steering groups. There was a high acceptance of the pathway, which we believe was partly owing to the fact that it was developed jointly with all relevant parties. The significance of these data lies in the relative simplicity of the pathway, along with the significant increase in psychosocial assessments requested and completed. This formula will help solve one of the many problems UK hospitals are currently experiencing. Furthermore, these results emphasise the importance of placing liaison psychiatry teams within hospital A&E departments, as well as the establishment of self-harm steering groups to develop local pathways and protocols.

After the introduction of the pathway the number of people presenting to the A&E department with self-harm was considerably reduced (27%), coinciding with a 10% reduction of people presenting with a history of self-harm. This reduction cannot be explained by a national trend or by any other specific hospital intervention. It is unfortunate that this audit could not collect the necessary data that would show an association between reduced presentation with self-harm and the introduction of the pathway. More studies are needed to examine whether such a link exists.

Although we have robust data regarding the increase of psychosocial assessments there remain patients who do not receive such assessments despite local efforts. It is still unclear what intervention would most benefit this group. Furthermore, our data do not allow individuals to be followed up over 2 years and the overall reduction of self-harm presentations needs further research.
