Why it is time for a public health approach to preventing suicide

Background• GGB: Leading suicide

since 1937 – Approximately one suicide every 2-

3 weeks– 4 foot railing, no other barrier

• Not always the uncontested leader among sites worldwide

death every 40 seconds.

SUICIDE RISK

B ACUTE ON CHRONIC RISK

x yPeriod of extra

riskChronic risk

x yRisk periodNo risk

• Suicide acts are often impulsive

• Crises are often temporary

• 90% of survivors of near-lethal suicide attempts do not commit suicide thereafter

Means Restriction as a Suicide Prevention Strategy

SURVIVORS OF SELF-INFLICTED SHOOTING

• 33 survivors of self-inflicted firearm injuries

• Most common reason for shooting was interpersonal conflict with partner or family members (21 patients)

• Act almost always described as impulsive

• All used firearms available in household and availability was often reason given for choice of this method

(De Moore et al, 1994)

Impulsivity

ImpulsivityFactors associated with the medical severity of suicide attempts in youths and young adults (Swahn MH, Potter LB, 2001)

•25% of 153 survivors of near lethal suicide attempts acted within 5 minutes of the impulse to do so

•71% acted within one hour

Sri Lanka Pesticide Suicides (Eddleston, 2006 JCT)

•268 self-poisonings, 85% noted choice of poison dictated by what was readily at hand

•Little premeditation

On the bridge, Baldwin counted to ten and stayed frozen. He counted to ten again, then vaulted over. “I still see my hands coming off the railing,” he said. As he crossed the chord in flight, Baldwin recalls, “I instantly realized that everything in my life that I’d thought was unfixable was totally fixable—except for having just jumped.”

Tad Friend. Jumpers. The New Yorker (2003)

CRISIS | same-day• Did suicide occur within 24 hours of a

very recent crisis or precipitating event?– e.g. arrest, job loss, argument, relationship

break-up, legal trouble, police pursuit, bad report card

• Purpose is to identify suicides that may have an impulsive element

Crisis, same day

Victim was a 16 year-old boy who had been suspended from school for misbehavior. His mother grounded him and they got in a loud argument. He ran from the room, slammed the door, went to the basement and shot himself with his father’s rifle. No known mental health history.

Table 1. Longitudinal Association between Household Gun Ownership and Suicide Mortality: Percent Decrease in Mortality Rate for each 10% Decrease in Household Firearm Ownership Level (1981-2001), adjusted for age, unemployment, poverty, per capita alcohol consumption and region of the country

Why might declines occur?– Improved life circumstances– Improved mental health – Improved mental health treatment (SSRIS?)– Cohort characteristics– Changes in social norms– Coding changes– Changes in population (e.g. large influx of

immigrants with lower suicide rates; change in age distribution)

In most of these scenarios, we would expect to see attempts and completions by all methods going down.

• 75% prescription medication• 86% OTC medications• 2% street drugs

– 95% had some medication available at time of SA

• 25% firearms

At follow-up

~10% reported that injury prevention education was given about restricting access medication– 86% locked up medications (vs. 32% of those w/o IP education)

No one (0%) reported being told that firearms in the home increase the risk of suicide

76% of the adults were not worried about thepossibility of a repeat suicide attempt by their adolescent

Active OppositionIn early 2006, two separate but virtually identical

bills were introduced in the Virginia and West Virginia legislatures

– Each bill would have prohibited a physician from asking a patient if he or she owned firearms for the purpose of counseling that patient about ways to reduce risks associated with firearms

– Penalties for violation of the bills included revocation of a physician's license to practice

Counseling about firearms: proposed legislation is a threat to physicians and their patients. Vernick JS, Teret SP, Smith GA, Webster DW. Pediatrics 2006; 118(5):2168-72

22. “Oral or written inquiry to a patient concerning the possession, ownership, or storage of firearms, where such inquiry has no relationship to the practice of the healing arts or the medical condition of the patient, and is for the purpose of gathering statistics or to justify patient counseling, unless such inquiry is the subject of a request, or related to a medical complaint, made by the patient.”

Case Control: Cornwell et al All Suicides, 65 years and olderLarge study (86 cases and 86 community controls matched on age, sex, county of residence)

•Results: –Presence of a firearm in the home was associated with increased risk for suicide, even after controlling for psychiatric illness.–Elevated risk was accounted for by access to handguns rather than long guns–RR more pronounced in men than women–Storing the weapon loaded and unlocked were independent predictors of suicide

Cornwell, Am J Geriatric Psychiatry, 2002

Case Control: Wiebe

All Suicides drawn from the 1993 National Mortality Followback SurveyLarge study (1,959 cases and 13,535 controls from National health interview Survey matched on age, sex, race)

•Results: –Presence of a firearm in the home was associated with increased risk for suicide: 66% of suicides lived in households with guns vs. 37% of controls–OR=3.4 (3.1, 3.9)–Elevated risk was accounted for by access to handguns rather than long guns

Wiebe, AEM,41(6): 771-82, 2003

Guns used in suicide • Among 35 gun suicide victims aged 17 and under, the

owner of the gun was documented in 26 cases.• In 92% of cases (24/26), the gun came from the family.
