File List A. Filename: nrls_data_open.csv Short description: Full dataset with names of rare drugs redacted to prevent identification of cases. Free-text variables are also redacted to prevent identification of the case, as required by data sharing agreement with NHS England. Can be archived for open access. CSV format. Created 20230825 B. Filename: nrls_data_confidential.csv Short description: Full dataset with no redaction of rare drug names. Free-text variables are also redacted to prevent identification of the case, as required by data sharing agreement with NHS England. Only for confidential archiving. CSV format. Created 20230825 C. Filename: data_sharing_agreement.pdf Short description: Data sharing agreement signed with NHS England to allow release of original data. Only for confidential achiving. PDF format.

People involved with sample collection, processing, analysis and/or submission: Initial inductive coding was performed by Shaojun Liu with inter-rater reliability checks by Bryony Dean Franklin. Pilot coding and inter-rater reliability checks were performed by Matthew Jones, Freyja Powell, Asma Samsor, Felicity Ting Chao Ru, Nikolaos Veliotis and Yin Mei Wong. Final coding and inter-rater reliability checks were performed by Freyja Powell, Asma Samsor, Felicity Ting Chao Ru, Nikolaos Veliotis and Yin Mei Wong. ----------------------------------------- DATA-SPECIFIC INFORMATION FOR: nrls_data_open.csv and nrls_data_confidential.csv ----------------------------------------- 1. Number of variables: 23 2. Number of cases/rows: 5708 3. Variable List A. Name: incidentID Description: Unique incident identification number B. Name: CareSettingofOccurrence Description: Care setting in which in the incident occurred C. Name: Locationlvl1 Description: Higher level (less detailed) location in which the incident occurred D. Name: Locationlvl2 Description: Lower level (more detailed) location in which the incident occurred E. Name: Guidelinecausecategory Description: Primary coding of deviations from expected practice in the incident (detailed). Three character codes where the first character is a number (1 to 3), the second character is a letter (A or R) and the third character is a number (1-5) record deviations from expected practice. The first number records the hierarchical task analysis step from deviation occurred (i.e. step 1, 2 or 3) and the following two characters record the associated error mode (A1, R1, R2, R3, R4 or R5). See paper for full definitions. C1 = Guideline not followed for a reason unrelated to finding or understanding a guideline C2 = Guideline not followed, reason unknown C3 = Guideline content incorrect or out-of-date D = Report not related to guideline use E = Insufficient information to determine if guideline followed Not = Does not relate to a medication incident F. Name: HighLevelCause Description: Primary coding of deviations from expected practice in the incident, described at higher (less detailed) level 1 = deviation from hierarchical task analysis step 1 2 = deviation from hierarchical task analysis step 2 3 = deviation from hierarchical task analysis step 3 4 = incident does not describe a deviation from the hierarchical task analysis G. Name: Guidelineinvolved1 Description: Primary coding of a clinical guideline involved in the incident BNF = British National Formulary Medusa/IMG = NHS Injectable Medicines Guide (Medusa) SPC = Summary of Product Characteristics N/A = not applicable (guideline not involved) H. Name: Guidelinesinvolved2 Description: Primary coding of a clinical guideline involved in the incident BNF = British National Formulary Medusa/IMG = NHS Injectable Medicines Guide (Medusa) SPC = Summary of Product Characteristics N/A = not applicable (guideline not involved) I. Name: Guidelinesinvolved3 Description: Primary coding of a clinical guideline involved in the incident BNF = British National Formulary Medusa/IMG = NHS Injectable Medicines Guide (Medusa) SPC = Summary of Product Characteristics N/A = not applicable (guideline not involved) J. Name: DoublecheckGuidelinecausecategory Description: Secondary coding of deviations from expected practice in the incident (detailed) (variable 'Guidelinecausecategory') for calculation of inter-rater reliability. Definitions of codes identical to 'Guidelinecausecategory' K. Name: SpecialtyLvl1 Description: Higher level (less detailed) clinical specialty in which the incident occurred L. Name: SpecialtyLvl2 Description: Lower level (more detailed) clinical specialty in which the incident occurred M. Name: ReportedDegreeofHarm Description: The reported degree of patient harm associated with the indident. No harm = patient no harmed Low = minimal harm – patient(s) required extra observation or minor treatment Moderate = short term harm – patient(s) required further treatment, or procedure Severe = permanent or long-term harm Death = death caused by the incident N. Name: MedProcess Description: Stage of the medication use process at which the incident occurred O. Name: MedErrorCategory Description: The type of medication error associated with the incident P. Name: ApprovedNameDrug1 Description: Generic name of a drug involved in the incident Q. Name: ApprovedNameDrug2 Description: Generic name of a drug involved in the incident R. Name: ProprietaryNameDrug2 Description: Brand name of a drug involved in the incident S. Name: ProprietaryNameDrug1 Description: Brand name of a drug involved in the incident T. Name: RouteDrug1 Description: Route of administration of a drug involved in the incident U. Name: Year_of_Occurrence Description: Calendar year in which in incident occurred V. Name: Term1 Description: Full NRLS search term matched in free-text variable (not shown due to confidentiality concerns) leading to inclusion of the incident in the study W.
