Falls in community-dwelling older adults are the most frequent cause of injury. Every year, 30% of the adults over the age of 65 years fall increasing to 32-42% among those aged ≥ 75 years. Most falls have a multifactorial aetiology such as previous falls, advanced age, cognitive impair-ment, environmental risks, and hazardous activities, along with presence of chronic disease, muscle weakness, gait and balance disorders, and medication use Especially the use of fall-risk-increasing drugs (FRIDs) is a prominent risk factor.~Recently, The European Geriatric Medicine Society (EuGMS) Task and Finish Group published a consensus paper classifying 14 medication classes as fall-risk-increasing drug (FRID) (14). Most of them were psychotropics, but several new possible FRIDs were identified. However, the group did not reach consensus on 17 medication classes as potential FRIDs.~Therefore, to achieve a better understanding of these 17 medication classes as potential FRIDs, more studies taking these issues into account are warranted.~Primary objective:~To examine the association between use of the potential FRIDs and falls rate with a 1-year follow-up in a cohort of community-dwelling older adults, aged 75 years or more.~Study design and sample:~A prospective cohort study with 1-year follow-up will be performed in collaboration with the municipality of Hjørring, Denmark. The sample size was derived without a recommended power calculation; hence, the sample size builds on feasible recruitment within the 13 months inclusion period granted by the municipality due to economical and administrative reasons.~Study setting, participants, data collectors, process of recruitment and data collection:~According to Danish legislation on health and social services, Danish municipalities are responsible for developing and initiating prophylactic and health-promoting initiatives for their senior citizens. This is done through different authorities in the municipality (e.g. preventive-home-visits, senior activity centres). Also, the municipality of Hjørring administers a local hall for citizens together with general- and patient associations. Therefore, data collection will be performed in participants' own homes through preventive-home-visits, at senior activity centres and at the local hall in the municipality of Hjørring, Denmark.~Baseline characteristics:~Data collection was performed at baseline and based on a multifactorial falls risk test battery in-cluding various physical tests (static balance under dual-task conditions, grip- and lower limb strength, reaction time of lower limbs and gait speed); self-report questionnaire on sociodemo-graphic characteristics, frailty, nutrition, disability, fear of falling, health-related quality of life, depressive symptoms, several physical symptoms, cognitive tests; and reporting of comorbidities (23). The participants' comorbidities were obtained from the participants' hospital records and the diagnoses were indexed according to the International Classification of Diseases 10th revision (ICD-10).~Baseline medication:~To determine the participants' medications at inclusion, the investigators consulted the national Shared Medica-tion Record (SMR). The SMR is a national registry of current medication use and pharmacy rec-ords of prescriptions to each citizen in Denmark. Any physician involved in the patients' clinical course has access to the SMR data and all details of each prescription and the date of the latest medication reconciliation are provided (24). For each participant all medication registered in SMR at baseline was documented and indexed according to the WHO-recommended anatomical therapeutic chemical (ATC) medication classification system.~Confounding covariates:~Many different risk factors and predictors for falls in older adults have been described previously. All these risk factors are possible confounders to the potential FRIDS; hence, the following a priori list specifies the confounding variables to be adjusted for in the multivariate regression model:~Age~Sex~History of previous falls~The comorbidity related to the potential FRID to adjust for confounding by indication~Fear of falling using Short Falls Efficacy Scale-International 7-item~Gait speed measured with a 4-meter walk test~Cognitive impairment estimated by the Orientation-Memory-Concentration test per-formed over the telephone~Frailty using the Tilburg Frailty Indicator~Physical and instrumental disability in activities of daily living using the Vulnerable El-ders Survey 13 .~Depressive symptoms using Geriatric Depression Scale 4 item, a depression diagnosis or prescription of any antidepressants~Use of benzodiazepines, benzodiazepines derivatives or non-benzodiazepines (Z-drugs)~Use of opioids
The European Geriatric Medicine Society (EuGMS) Task and Finish Group published a consensus paper on fall-risk increasing drugs. However, the group did not reach consensus on 17 medication classes as potential FRIDs. Thus, in this study the investigators want to examine the association between use of these potential FRIDs and falls rate with a 1-year follow-up in a cohort of community-dwelling older adults, aged 75 years or more.
