Protective factors are under-researched but are likely to lie in the nature of psychiatric care.
Consequently, community care may affect suicide by altering the level of protection at critical periods in an episode of illness. The clinical prevention of suicide should therefore be a priority for community services, and the relationship between suicide and mental health care should be researched by a national process of monitoring. The authors thus believe that they have documented for the first time that outbreaks of suicide occur more frequently than expected by chance alone. The occurrence of suicide clusters among teenagers appeared to vary considerably by state and year of investigation. There is some indication that there has been an increase in teenage clusters in more recent years.
