Summary
Dentists developed new systems to classify dental adverse events (AEs), finding pain and infection most common. These classifications help prevent patient harm in dental care.
Area of Science:
- Dental Medicine
- Patient Safety
- Healthcare Quality Improvement
Background:
- Dental professionals aim for safe and effective oral healthcare.
- Adverse events (AEs), defined as unnecessary harm from dental treatment, can occur.
- Existing medical AE classification systems were adapted for dentistry.
Purpose of the Study:
- To propose and evaluate two systems for categorizing the type and severity of dental AEs.
- To develop and refine dental-specific AE classification systems.
Main Methods:
- Reviewed and adapted existing medical AE classification systems for dental use.
- Developed two initial dental AE classification systems.
- Eight reviewers conducted chart reviews, using identified AEs to evaluate and modify the classifications.
Main Results:
- Reviewed 958 charts, identifying 118 prospective AEs, with 101 (85.6%) verified.
- Developed a final AE type classification with 12 categories and an AE severity classification with 7 categories.
- Pain (56%) and infection (17%) were the most frequent AE types, accounting for 73% of cases. 88% of AEs caused temporary, moderate to severe harm.
Conclusions:
- Successfully classified dental AEs using novel type and severity classifications.
- Understanding AE types and severity is crucial for learning from and preventing patient harm in dental settings.

1.9K
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.

Pharmaceutical poisoning can occur through various channels, impacting an estimated 2 million hospitalized patients in the U.S. annually with serious adverse drug responses. These scenarios encompass both therapeutic uses, such as drug toxicity, where even standard dosages can lead to severe central nervous system depression, and non-therapeutic exposures, including accidental ingestion by children, and environmental and occupational exposures.Unintentional poisonings often involve exploratory...
