However, the lack of a specific indicator for pregnancy-related case reports within the international standard for transmission of individual case safety reports complicates the retrieval of such reports in pharmacovigilance databases. To address this, an algorithm to identify reports of exposures during pregnancy was developed in VigiBase, the World Health Organization global database of adverse event reports.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;We aimed to evaluate and characterise the VigiBase pregnancy algorithm.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;The rule-based algorithm uses multiple structured data elements in the International Council of Harmonisation (ICH) E2B transmission format that could potentially hold pregnancy-related information, to determine if a case report qualifies as a pregnancy case. Free text information is not considered. Three datasets were used for the evaluation. The \"Full dataset\" comprised deduplicated VigiBase data up to January 2023. The \"Downsampled dataset\" was a subsample of the Full dataset, adjusted to increase the prevalence of pregnancy reports by excluding individuals aged 45 years or older and male individuals aged 18 years or older, used to evaluate recall (i.e. sensitivity). The \"Random dataset\" was a straight random sample of the Full dataset, used to evaluate precision (i.e. positive predictive value). As a baseline for comparison, the Standardised Medical Dictionary for Regulatory Activities (MedDRA&lt;sup&gt;®&lt;/sup&gt;) Query (SMQ) \"Pregnancy and neonatal topics (narrow)\" was used. To provide a gold standard for the evaluation, case reports were manually annotated as either \"pregnancy case\" or \"non-pregnancy case\", for all reports in the Downsampled dataset, and for the reports flagged as pregnancy cases by the algorithm or the SMQ baseline in the Random dataset.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;In the Downsampled dataset with 7874 annotated reports, 253 reports were annotated as pregnancy cases. Of those, the algorithm recalled 75% (95% confidence interval [CI] 69-80), increasing to 91% (95% CI 86-95) when restricting the analysis to reports adhering to the ICH E2B format. Preprocessing obstacles of incomplete mapping of specific pregnancy terms to MedDRA&lt;sup&gt;®&lt;/sup&gt; led to most false negatives followed by pregnancy information confined to free text information. The SMQ baseline had a lower recall of 62% (95% CI 56-68). In the Random dataset with 30,000 reports, the algorithm flagged 344 reports, among which 316 were annotated as pregnancy cases, leading to a precision of 92% (95% CI 88-95). The main reasons for false positives were postpartum indications, non-pregnancy-specific events or information miscoded as pregnancy related.

Duplicate reports, defined as multiple reports of the same adverse event(s) related to the administration of the same marketed product(s) to the same individual patient at a particular point in time, may be received in FAERS for many reasons.

Key comparison features included: report and reporter type, country of report origin, data source for report, and outcome. In addition, we evaluated information similarity of reports for seven data elements (e.g., age, sex, suspect products) within sets of duplicates using both structured and unstructured fields.

Limiting the anticholinergic burden (ACB) among older patients has been advocated for decades, but reliable population-level data on temporal trends are lacking. Here, we estimated the cumulative incidence and incidence rates (IRs) of a cumulative ACB score of three or more (cACB ≥ 3) among older adults in a community-dwelling population and described the changes in IR over the past 25 years.</p><p><strong>Methods: </strong>Within the population-based Rotterdam Study, pharmacy dispensing records were obtained from 11,038 individuals aged 65+ years from 1996 to 2020. The cACB score was calculated with the Anticholinergic Cognitive Burden Scale and supplemented with drugs on the ACB scale by the Expertisecentre PHarmacotherapy in OldeR people (EPHOR).
