AIMS AND METHOD
NHS Direct is increasingly used as a first source of health advice and information, receiving an average of 600 000 calls per month. We performed an audit of suicides in Hampshire and the Isle of Wight over a 2-year period to determine the characteristics of those who died by suicide and had been in recent contact with NHS Direct.
RESULTS
Of 278 suicides resident in Hampshire and the Isle of Wight, 30 (10.8%) had contacted NHS Direct in the preceding year. Of the 30 callers within the preceding year, 12 (40%) made multiple calls, 7 (23%) called within 2 weeks of death, 9 (30%) callers reported mental health problems, 17 (57%) reported physical problems, and 4 (13%) just requested information. Eighteen (60%) calls resulted in urgent medical referral, 17 to a general practitioner and 1 to accident and emergency.
CLINICAL IMPLICATIONS
The high incidence of physical, often pain-related, problems merits further investigation.

With around 5000 people dying by suicide in England every year, suicide is a major public health issue (Department of Health, 2002). Luoma et al (2002) suggest that rates of contact by individuals before they died by suicide are significantly higher for primary care providers than for mental health service providers. In a systematic review of studies examining the extent to which individuals made contact with mental health and primary care providers before suicide, Luoma et al (2002) conclude that over half of those completing suicide had made contact with a primary care professional in the month before death, and around three-quarters had contact within 1 year of suicide.
Over recent years, the range of available primary care services in the UK has developed to include ‘fast access’ provision such as NHS ‘walk-in’ centres and NHS Direct. NHS Direct in particular is being increasingly used as a first point of contact for members of the public seeking health advice and information, with numbers of contacts averaging 500-600 000 calls a month (NHS Direct, 2005; Hansard, 2005). Calls relating to mental health form a small but significant proportion of this workload. NHS Direct operates as a telephone-based, ‘first level’ health screening and advice service. Clinical triage is performed by nurse advisors who use evidence-based algorithms within the NHS Clinical Assessment System to assess symptoms and provide advice, sign-posting and referral. A recent 3-month audit of the use of mental health algorithms showed that the depression screening algorithm was used 5374 times and the suicide algorithm was used 3976 times (NHS Direct unpublished data, details available from the authors on request).
This 2-year audit was designed to ascertain the proportion of suicides who had contacted NHS Direct in the year preceding their death, the reason for contact, the protocol used to assess the query and the advice given, and to compare characteristics of suicides in contact with NHS Direct with suicides in the same general population.

Permission was obtained from all coroners in Hampshire and the Isle of Wight to allow NHS Direct to check names against NHS Direct databases. All persons who died by suicide (ICD-9 codes E950-959; World Health Organization, 1977) and deaths from similar causes on which an open verdict (ICD-9 E980-989, excluding E988.8) was recorded, collectively called ‘suicides’, were identified from coroners’ records in Hampshire and the Isle of Wight. Residents whose inquest was held outside the area were identified from mortality files (2002-2003) of the Office for National Statistics. A very few inquests held in 2003 and 2004 might have been missed because they did not appear on the 2003 mortality file or occurred outside the area during 2004. Names of those dying by suicide between 1 September 2002 and 31 August 2004 inclusive, who were either residents of Hampshire or the Isle of Wight, or whose inquest was held by a coroner in this area, were checked against the records of NHS Direct Hampshire and the Isle of Wight.

Characteristics of suicides
A verdict of suicide or open verdicts were returned on 278 residents of Hampshire or the Isle of Wight who died between 1 September 2002 and 31 August 2004 inclusive. Thirty (10.8%) of these residents had telephoned NHS Direct within 12 months of their death.
There was no significant difference between the 30 recent NHS Direct contacts and the other suicides with respect to the proportion of suicide (83 v. 71%), males (67 v. 75%), mean age (50 years (s.d.=19.0) v. 46.2 years (s.d.=17.0 years)) (Table 1), or cause of death (33% fatal overdose v. 27% fatal overdose). The only significant difference was in the greater proportion of Isle of Wight residents (25%) who had contacted NHS Direct compared with 8.4% of Hampshire residents dying by suicide (difference 16.6%, 95% CI 2.7-30.5, P=0.05).

The male/female ratio for all suicides from Hampshire and the Isle of Wight and for those not in recent contact with NHS Direct was 3:1, which is similar to that in England and Wales. The gender profile among recent NHS Direct contacts (male/female ratio 2:1) is roughly the reverse of the usual gender profile for NHS Direct whereby female callers constitute about six of every ten calls.
Frequency of contact
Although 18 (60%) callers had made only one call, the number of calls made
by an individual ranged from 1 to 12. More males (14: 70%) than females (4:
40%) made only one call but the gender difference was not significant.
Interval between last call and date of death
The interval between the last contact with NHS Direct and death ranged from
1 to 315 days. Significantly more females (5: 50%) than males (2: 10%) had
contacted NHS Direct in the 2 weeks before death (difference 40%, 95% CI
6.3-3.7, P=0.05). There was no significant difference between the
proportion of calls relating to physical health among the 7 calls made within
2 weeks of death (2: 28.6%) and the 23 calls made between 2 weeks and 12
months before death (14: 60.9%, difference 32.3%, 95% CI –71.3 to 6.7)
or between the proportions of the mental health-related calls in the 2 weeks
before death (3: 42.9%) and between 2 weeks and 12 months before death (6:
26.1%, difference 16.8%, 95% CI –24.0 to 57.6).
Reasons for calling and screening algorithms
The ‘call reason’ is a brief description of the caller’s
presenting problem as logged by the call-handler prior to the call being
passed either to a nurse advisor for clinical assessment of symptoms or - for
non-symptomatic calls - to a health information advisor for provision of
health information. Although mental health problems (including 3 reporting
suicidal ideation) accounted for 9 of the last calls made by the 30 people
dying by suicide (Table 2),
physical health problems were the reason for the majority of calls (17). Pain
was mentioned by 16 callers. Mental health algorithms were used in 8 of the 30
calls. However, the majority of calls appeared to be primarily about physical
problems and this was reflected in the algorithms selected by the nurse
advisors.

Advice given
Over half the calls resulted in a referral to general practitioner (GP)
services. Eleven callers were advised to contact their GP urgently (as soon as
possible or within 4 hours) and one was advised to attend an accident and
emergency department as soon as possible. Over a quarter of calls resulted in
the provision of health information as opposed to onward referral.

The similarities between the NHS Direct callers and other suicides in Hampshire and the Isle of Wight suggest that the callers are a representative sample. The high incidence of physical problems, particularly problems associated with pain, relative to mental health problems in this population was unexpected and merits further investigation. Since it has been reported that suicidal intent is discussed in only 22% of last primary care consultations (Isometsa et al, 1995), the identification of such intent in NHS Direct contacts presents a challenge.
Conclusions
The information gleaned from this small sample of calls highlights the
potential role of NHS Direct in the identification, assessment and referral of
individuals who may be at risk of suicide. The preliminary findings suggest a
higher than expected number of completed suicides of individuals presenting
with purely physical symptoms. There is clearly scope for examining the extent
to which the current NHS Direct screening process succeeds in identifying and
assessing suicidal symptoms, and how it could be developed to elicit suicidal
ideation which might be masked by a somatic presentation.
The NHS Direct system of routinely recording all patient contacts as part of the clinical case record provides a unique and hitherto untrodden path into the field of suicide research, as it offers the potential to listen to the voice of the individual at a critical time prior to death. Clearly, the length of the interval between the last call and the date of death will be a significant factor in selecting those calls which could benefit from examination. A formal analysis of such calls made within a defined time frame using qualitative research methods may provide valuable clues to the caller’s mental state at the time of the call and offer the potential to develop improvements in service response to such callers.
We thank the coroners in Hampshire and the Isle of Wight; Anna Walker (formerly Mental Health Lead at NHS Direct, Hampshire) who acted as liaison between NHS Direct and the University of Southampton Mental Health Group and who, with the assistance of Caren Sargant (nurse advisor), matched the names provided by the coroner to records in the NHS Direct database; the NHS Direct Mental Health Team and all other staff at NHS Direct for providing valuable feedback on the preliminary drafts.
