“…One of these studies concluded fairly reliable suicide statistics, one 0-10% under-reporting and one concluded 11-30% under-reporting. Twenty-one studies got a sum score 10-14 [8,9,11-13,15-17,20-23,27-32,35,37,38] and seven studies sum score ≤9 [10,14,18,19,25,26,34]. Five of the studies with quality sum score ≤9 concluded > 30% under-reporting or poor suicide statistics, one concluded 0-10% under-reporting.…”

BackgroundReliable suicide statistics are a prerequisite for suicide monitoring and prevention. The aim of this study was to assess the reliability of suicide statistics through a systematic review of the international literature.MethodsWe searched for relevant publications in EMBASE, Ovid Medline, PubMed, PsycINFO and the Cochrane Library up to October 2010. In addition, we screened related studies and reference lists of identified studies. We included studies published in English, German, French, Spanish, Norwegian, Swedish and Danish that assessed the reliability of suicide statistics. We excluded case reports, editorials, letters, comments, abstracts and statistical analyses. All three authors independently screened the abstracts, and then the relevant full-text articles. Disagreements were resolved through consensus.ResultsThe primary search yielded 127 potential studies, of which 31 studies met the inclusion criteria and were included in the final review. The included studies were published between 1963 and 2009. Twenty were from Europe, seven from North America, two from Asia and two from Oceania. The manner of death had been re-evaluated in 23 studies (40-3,993 cases), and there were six registry studies (195-17,412 cases) and two combined registry and re-evaluation studies. The study conclusions varied, from findings of fairly reliable to poor suicide statistics. Thirteen studies reported fairly reliable suicide statistics or under-reporting of 0-10%. Of the 31 studies during the 46-year period, 52% found more than 10% under-reporting, and 39% found more than 30% under-reporting or poor suicide statistics. Eleven studies reassessed a nationwide representative sample, although these samples were limited to suicide within subgroups. Only two studies compared data from two countries.ConclusionsThe main finding was that there is a lack of systematic assessment of the reliability of suicide statistics. Few studies have been done, and few countries have been covered. The findings support the general under-reporting of suicide. In particular, nationwide studies and comparisons between countries are lacking.

“…Consequently, all such deaths were assumed to be bona fide suicides (32). However, some suicides may not be coded as such on death certificates (9,25,26); so we also identified other suspicious deaths through the medical index (32). For each candidate case, the patient's complete (inpatient and outpatient) medical records were reviewed until it was possible to know the death was not a suicide.…”

“…Most studies have found no association between suicide and birth date (17)(18)(19)(20)(21)(22) but found fewer suicides during the quarter of the year preceding the birth date (4%) and a significant excess (43 2) during the quarter after (23,24). However, studies that address suicide timing from death certificate data may be biased by errors in the reported date of suicide and by the fact that suicides are sometimes certified as deaths due to other causes (9,(25)(26)(27). Rich et al (28) deemed the interval between the suicidal act and subsequent death to be significant, although others have found the interval to be inconsequential for research purposes (14,29).…”

“…Rich et al (28) deemed the interval between the suicidal act and subsequent death to be significant, although others have found the interval to be inconsequential for research purposes (14,29). Estimated percentages of suicide incidence underreporting range from 20% to 50% (30,31) and, in one study that minimized ascertainment bias, the suicide incidence was twice the official statistic (26).…”

Previous studies of suicide timing may have been biased by incomplete ascertainment of suicides and by delays between the suicidal act and subsequent death. Those potential biases were assessed and minimized in this population-based study by using the unique resources of the Rochester Epidemiology Project in Olmsted County, Minnesota. Using these more accurate data, we confirmed previous reports of no excess suicides on birthdays (+/- 3 days), or during 3 United States national holidays. While most prior reports found excess post-holiday suicides and suicide peaks on Mondays, those findings were not observed in Olmsted County. Because 93% of deaths occurred on the date of the suicidal act, using date of death instead of the actual date of suicide is sufficient for most research purposes.

-Objective:To analyze the epidemiology of parasuicide in Canary Islands.Methods: Emergency Department reports at every Hospitals and clinical data of all Mental Health Units were revised in Tenerife (1992-1996) and in Gran Canaria (1994-1996. Data about age, sex, address, educational level, marital status, job situation, time and methods used for committing parasuicide and previous parasuicide events were collected.Results: In Tenerife Island the annual average was 355 parasuicides among which 24.9% of the episodes were repeaters. The average crude rate was 70.99 cases per 100.000 inhabitants and the standardized rate was 61.81. In Gran Canaria Island the annual average was 634 and 21.3% were repeaters. The average crude rate was 120.23 per 100.000 and the standardized rate was 103.7 per 100.000. The age group 15-34 years, showed the higher rate values. Women presented higher rates as compared to men in all age categories.Conclusion: These findings are in agreement with those of the WHO-EURO Multicentre Project on Parasuicide. We found in Tenerife the lowest parasuicide rate values published in Europe.
