Are the reports of the adverse drug events (ADE) submitted by pharmacists are different in quality and quantity compared to those submitted by physicians and nurses?


The answer is yes. This retrospective observational study had shed light on the major differences between ADE reports submitted by pharmacists compared to physicians and nurses. Physicians and nurses reported mostly type B ADRs, which are typically ADE that are pharmacologically unexpected, such as allergic reactions. As a result, the dermatological system was the affected body system that was most commonly reported by physicians and nurses. On the other hand, pharmacists tended to report mostly type A ADE, which are ADE that are expected from the medical treatment, such extrapyramidal side effects from antipsychotics. Expectedly, pharmacists’ ADE reporting included many different body systems, including the CNS and the cardiovascular system.


Our findings show that pharmacists' reports are complimenting the reports submitted by physicians and nurses. While physicians report focus on obvious adverse drug reactions, pharmacists spend more time in investigating and identifying ADEs that are less obvious. The study shows that a multidisciplinary team is always needed for better care of patients.

Take-home messages • Pharmacists contributed more than other healthcare providers in ADE reporting in our setting. • Most of the submitted reports involved unpreventable type B ADRs that were possibly caused by the reported medications and were of high quality. • Pharmacists reported more preventable and type A ADE, and their reports had higher causality assessment scores than other healthcare providers. • Physicians’ and nurses’ reports had higher ADR quality scores than those of pharmacists.Dr. Noor Alsalimy, PharmD



Characteristics and quality of adverse drug reaction reporting:a comparison of pharmacists with other healthcare providersat a multi-specialty hospital in Qatar

Drugs Ther Perspect (2017) 33:283–289

Abstract Objective: Rumailah Hospital (RH) is a multi-specialty hospital with a capacity of 605 beds that serves subacute and long-term patients in Qatar. Since under-reporting and low-quality reporting of adverse drug reactions (ADRs) are widespread phenomena globally, there is a need for greater insight into pharmacists’ and other healthcare professionals’ roles in ADR reporting in RH. Thus, this study primarily aimed to compare the number, quality, and characteristics of ADR reports received from pharmacists compared with other healthcare providers at RH in Qatar. Methods: A retrospective descriptive analysis of ADR reports submitted by healthcare providers at RH between January 1, 2012 and October 1, 2014 was conducted. Results: A total of 92 ADR reports were submitted by different healthcare providers, of which 42.8% were by pharmacists, 38.4% by physicians, and 8.8% by nurses. Most of the physicians’ (65.7%), nurses’ (62.5%), and pharmacists’ (41.0%) ADR reports were judged to be of high quality (grade 2) based on the World Health Organization’s quality scheme (p[0.05). A causality assessment using the Naranjo algorithm revealed that 62.2% of the reports were ‘possibly’ caused by the suspected medications, while 31.1% were considered to ‘probably’ have been caused by the suspected medications (p\0.05). Furthermore, most of the ADR reports were type B (54.9%) and unpreventable (64.8%) according to the Medication Appropriateness Index. One hundred percent and 91.2% of nurses’ and physicians’ ADR reports were for unpreventable events, respectively, while 41.0% of pharmacists’ reports were for definitely preventable ADRs (p\0.05). Conclusions: ADR reporting at RH was undertaken by different healthcare professionals, and a high proportion of the reports were judged to be of high quality. ADRs reported were often unpreventable. There were differences between the characteristics and causality scores of ADR reports between different healthcare professionals. There is a need to develop interventions that will further increase ADR reporting as well as the quality of the reports.scores than those of pharmacists.
