Introduction Abbreviations are commonly used in medical records to save time and space but use in prescriptions can be a reason for communication failures and preventable harm during healthcare delivery. Nearly 5% of medication errors can be attributable to abbreviation use. Prescriptions need to be clear so that nurses and pharmacists can correctly interpret intentions of doctors. For patient safety, hospitals should implement a process for uniform use of approved abbreviations, such as through use of an approved list or never-use list of abbreviations and symbols. The study envisaged to assess impact of never use list in an apex tertiary care hospital in India. Methods The study design was pre-post interventional / quasi-experimental design to assess the impact of never use list and standardized abbreviations. The study was conducted after ethical approval from Institute Ethics Committee. Pre intervention data was collected by a retrospective closed in-patient medical record review. An approved Never use list and standardized abbreviations were developed and poster copies were affixed in inpatient wards, doctors were educated and poster pamphlets were also distributed. Post interventional incidence of error prone abbreviations was determined and the effectiveness of the same was assessed by using statistical analysis. Results Incidence of error abbreviations in inpatient prescription were 47.5% and Never Use list of abbreviation led to a statistically significant reduction of error-prone abbreviation by 8.2% from 47.5% to 43.6% (P\0.006) Conclusion Never Use lists are effective in reducing incidence of common error-prone abbreviations and discipline wise variation is observed. Adoption of such lists is highly recommended. The lists should be comprehensive, regularly updated and educational interventions should be comprehensive and integration into patient medical charts and pocket friendly flash cards may be provided for better outcomes. Enforcing a policy to prohibit the use of EPAs while prescribing will also be helpful.

Aim: The aim of the study was to assess the impact of never-use list and standardized abbreviations on error prone abbreviations Background: Abbreviations are commonly used in medical records to save time and space but use in prescriptions, which can lead to communication failures and preventable harm. Prescriptions need to be clear for correct interpretation. Hospitals should implement uniform use of approved abbreviations, such as an approved list or never-use list of abbreviations and symbols. In the hospital under study, there was no system of avoiding error prone abbreviations while prescribing any medication. Hence, an interventional study was performed to quantify and reduce the incidence of error prone abbreviations. Objectives: The main objectives were to determine the incidence of error prone abbreviations, development and implementation of ‘Never-use’ list and standardized abbreviations and finally determine its effectiveness in reducing the error prone abbreviations in the prescriptions. Methods: The study design was pre-post interventional / quasi-experimental design. The settings were inpatient wards of broad specialties of a tertiary care hospital. ‘Never-use’ list and standardized abbreviations were developed by review of relevant literature, existing lists by Institute for Safe Medication Practices and Australian Commission on Safety and Quality in Health Care compared against findings of pilot study of prescriptions for error prone abbreviations and experts’ input. Poster copies of the lists were affixed in inpatient wards, doctors were educated and poster pamphlets were distributed. Pre intervention data was collected by a retrospective closed in-patient medical record review. Post interventional incidence of error prone abbreviations was determined and the effectiveness of the same was assessed by using statistical analysis. Results: Incidence of error abbreviations in inpatient prescription was 47.5% and ‘Never Use’ list of abbreviation led to a statistically significant reduction of error-prone abbreviation by 8.2% from 47.5% to 43.6% (P\0.006). Conclusion: ‘Never Use’ lists are effective in reducing incidence of common error-prone abbreviations and discipline wise variation is observed.
