IONA Study Overview

Identify trends in enquiries to the NPIS (telephone and internet) relating to NPS and characterize and monitor the epidemiology of reported exposures Identify trends in the numbers of samples positive for NPS as identified in participating NHS laboratories Develop sophisticated mathematical models for analyzing NPIS and toxicology laboratory data Further develop methods of screening, analysis and quantification for new/emerging NPS in biological samples (urine, oral fluid and blood) Analyse samples from patients with acute severe toxicity relating to NPS to identify responsible agents Link the presence of analytically confirmed NPS exposure with the toxic effects experienced

Study 4. Collection of samples for research purposes from people attending participating emergency departments (Post amendment 1)

Study 4 Inclusion criteria Exclusion criteria  Patient with suspected novel psychoactive substance exposure  Presence of severe acute toxicity (See text)  Patient consent (immediate or retrospective)  Refusal of consent  Absence of severe toxicity  Children and young people <16 y  Samples collected for investigation of suspected non-accidental injury

Criteria for severe toxicity (present at any time after exposure) (Post amendment 1)

 Fever > 38.5 oC  Clinically important hypothermia  Glasgow coma scale < 8a  ITU/HDU/CCU admission  Respiratory insufficiency  Requirement for intubation and ventilation  Seizures  Hallucinations/psychosis  Extreme agitation  Severe or prolonged (> 24 h) behavioural disturbance  Arrhythmia  Chest pain or ECG evidence of cardiac ischaemia

  • r myocardial infarction

 Acidosis (arterial or venous pH < 7.35 or bicarbonate < 20 mmol/L)  Severe electrolyte or fluid disturbances  Hypoglycaemia (<1.7 mmol/L)  Methaemoglobinaemia (>50%)  Tachycardia > 140 /min  SBP > 180 mmHg  SBP < 80 mmHg  Acute kidney injuryb  Creatine kinase activity raised (> 1000 IU/L)  ALT/AST activity > 300 IU/L  PT > 15 s or INR > 1.3  Death  Poisons Severity Score61 of 3 (Severe) c  Other severe manifestations of toxicity, as determined and justified by the investigator

aIn the absence of likely alternative causes (e.g. severe alcohol intoxication, use of sedative drugs etc). bDefined as a rise in serum creatinine of ≥26 micromol/litre within 48 hours, a 50% or greater rise in serum creatinine

known or presumed to have occurred within the past 7 days, or a fall in urine output to less than 0.5 ml/kg/hour for more than 6 h63

cCriteria for PSS 3 relevant to recreational drug use include abnormal chest Xray with symptoms, generalized paralysis,

blindness or deafness

Data provided

  • Clinical records retained by the local researcher.
  • Information passed on to the research team in Newcastle will

include

– study number – the age, sex and postcode (first 4 digits) of the patient – nature and timing of the exposure – timing of sample collection – recorded clinical features (structured data collection form). – The great majority of samples and data will be provided with consent – there will be a small number of samples collected without consent from adults with incapacity by means of appropriate declarations from consultees (England and Wales)
