A highly granular dataset of 11,267 deliberate self-poisoning admissions curated by PIONEER. The data includes demography, diagnostic codes (ICD-10 & SNOMED-CT), presenting symptoms, procedures (OPCS4 & SNOMED-CT, prescriptions, referrals, follow-ups, and outcomes. The current dataset includes admissions from 03-12-2015 to 30-12-2023 but can be expanded to assess other timelines of interest. This dataset provides a clear understanding of self-poisoning in relation to different patient characteristics. The data also provides the type of drug taken (narcotic, non-opiod etc) and where (home, street, industrial areas etc) . Furthermore, assessments can be made on the impact of mental health service referrals and the likelihood of readmission with a subsequent overdose.
