LETTER TO EDITOR
Suicidalbehavioriscurrentlythoughtofasacontinuum. Althoughthereisawidevarietyofsuchbehavior,mostofthe informationfortheconstructionofepidemiologicalstandards isstillderivedfromstatisticsofdeathbysuicide.However,the burdenassociatedwithsuicideattemptsrepresented1.4%of theoverallburdenofdiseasesin2002.Itisestimatedthatthis figurewillreach2.4%in2020.1
Ourstudyevaluated121patientswhohadbeenhospital-izedbecauseofmedicallyseveresuicideattempts,atHospital dasClínicasoftheUniversidadeEstadualdeCampinas.Beck’s SuicideIntentScale(IS)wasusedformeasuringthepatient’s intention of dying.The degree of lethality was evaluated on asix-pointscale,basedonthepatient’sclinicalstatusandalso on the procedures performed during hospitalization, clinical parameters,threattolifeandtheattendingphysician’simpres-sions.TheSpearmancorrelationtestwasused,forallpatients andaccordingtoagegroups,toevaluatethecorrelationbetween suicidalintentandlethality.
Therewasacorrelationbetweensuicidalintentandlethal-ity(correlationcoefficientof0.42;p=0.04)withinthe30to 39-year-oldgroup(38individuals).Mostofthesepatientswere male(60%)andweremarriedorlivingwithsomeone(60%). 44%hadahistoryofpsychiatrictreatment.Poisoningwasthe methodmostcommonlyused(88%)and52%ofthepatients hadthediagnostichypothesisofaffectivedisorder.
Previousstudieshaveshownacorrelationbetweenlethality andintent,basedontheassumptionthattheindividualsare awareofthelethalpotentialoftheirsuicideattempt.2Inour study,westrictlyevaluatedseveresuicideattempts,carefully measuringsuicidalintentandlethality.
Wenotedthat,foratleastonethirdofthepatients,there wasacorrelation,albeitmoderate,betweenthedesiretodie andthelethalityofthemethodchosenforsuicide.Therefore, theresultinginjuriesweresevereandlife-threatening.Some ofthepatientswouldprobablyhavedied,hadtheynotbeen caredforinahospital.Inthefuture,wouldthesepatientsbe athigherriskofdyingthroughsuicide?Ifwetakethescientific literatureintoaccount,theanswerisyes.
Twoimportantsuicidepredictorsgatherseveralriskfactors. Firstly,previoussuicideattempts:inFinland,acohortstudyof 100attemptswasfollowedover37years,inthelongeststudy of this type ever made, revealing a suicide rate of 31.2%.3 Secondly,suicideattemptsresultinginsevereinjuries,posing
threattolife:inastudyinNewZealandwith302individuals inthiscategory,7%diedthroughsuicideafter5years.4
InBrazil,recentstatisticaldata(comparisonbetweenthe periodsof1980-82and1998-2000)showthatthesuicidecoef-ficienthasincreasedby32.8%amongmen.Inthemunicipality ofSãoPaulo,forexample,theyoungadultagegroup(25-44 yearsofage)accountsfor45%ofalldeathsduetosuicide.5
Insummary,ourfindingssuggestthatthesubgroupofpatients consistingofyoungadultswithmedicallyseveresuicideattempts areatgreaterriskofafuturesuicideattempt.Thus,whenidentified byhealthcareprofessionals,thesepatientsneedspecialattention.
