Correction to ‘Medication use among the oldest old in the Faroe Islands—A national cross-sectional study’

Niklasdottir S, Joensen N, Christensen K, Petersen MS. Medication use among the oldest old in the Faroe Islands—A national cross-sectional study. Basic Clin Pharmacol Toxicol. 2024;134(6):833–845. doi: https://doi.org/10.1111/bcpt.14012

In the above article, we wrote that 494 people aged 90 or older in the Faroe Islands were invited to participate. This is not correct as 66 of the 494 identified individuals passed away before the invitation letter was sent. Thus, 428 people received the invitation letter, and with 298 participating, the participation rate is 69.6%, not 60.3% as stated in the article.

Abstract

In this population-based cross-sectional study, 428 individuals ≥90 years were invited and 298 (69.6%) participated.

2.1 Study population

This study is a nation-wide, population-based cross-sectional study, with possible future longitudinal follow-up. All 494 individuals ≥90 years in the Faroe Islands by 1 August 2021 were identified through the Faroese Population Registry but 66 died before the invitation letter was sent. Thus, 428 individuals received an invitation letter explaining the study and asking consent for a research nurse to come to their residence (home or institution) to conduct a face-to-face interview, a concomitant clinical examination to assess their mental and physical functioning and draw a blood sample.

2.4 Results

Of the 428 individuals receiving an invitation, 298 individuals participated (69.6% of eligible residents) with a mean age of 93 years (range 90.2–106.2 years) and 69% (n = 205) women.

3.1 Strengths and limitations

A major strength of the study is the nationwide character of the study, including 69.6% of eligible individuals.
