Antihypertensive medications are frequently prescribed to the elderly. However, the association between these medications and the risk of fractures has only been minimally reported until the recent findings of a retrospective study. This study, conducted by Dave et al., analysed data from 64,710 older long-term care nursing home residents (mean age [SD]= 77.9[8.5] years). By using the propensity score matching approach, they reported that the incidence rate of fractures per 100 person-years in residents initiating antihypertensive medication (n=12,942) was 5.4 compared with 2.2 in the control arm (n=51,768), during a mean (SD) follow-up of 18.2 (8.7) days for the antihypertensive group and 16.8 (8.7) days for the control group. The findings corresponded to an adjusted hazard ratio (HR) of 2.42 (95% [confidence interval] CI, 1.43-4.08) cases of fractures per 100 person-years and an adjusted excess risk per 100 person-years of 3.12 (95% CI, 0.95-6.78). In addition, antihypertensive medication initiation and syncope are two factors associated with higher risk of severe falls requiring hospitalisation with a HR of 1.8 (05% CI, 1.53-2.13) and 1.69 (95% CI, 1.3-2.19) respectively. Besides, the magnitude of fracture risk was numerically higher among subgroups of residents with dementia (HR= 3.28, [95% CI, 1.76-6.1]), systolic blood pressure of 140 mm Hg or higher (HR= 4.41 [95% CI, 1.67-11.68]). It is recommended that additional monitoring should be implemented when initiating antihypertensive medication for individuals belonging to those vulnerable populations.
