- W3203399391 abstract "The use of disease-modifying agents (DMAs) to treat Multiple Sclerosis (MS) in older adults is debated as the disease activity decreases with aging. However, limited data exist regarding prescribing patterns of DMAs among older adults with MS.To examine prescribing patterns of DMAs and the factors associated with DMA prescribing practices among older adults with MS using electronic medical records (EMR) data.A retrospective longitudinal cohort study was conducted using the TriNetX, a federated EMR network from the US, data from 2016 to 2019. The study included older adults (≥60 years) with MS diagnosis and at least one prescription record during the study period. Patients with DMA prescriptions were identified and further classified into injectable, oral, or infusion users based on their last DMA prescription. A multivariable logistic regression model was used to evaluate the factors associated with prescribing of DMAs. A multinomial logistic regression model was also used to determine the factors associated with prescribing a particular dosage form of DMA.The study cohort consisted of 12,922 older adults with MS, with 2,455 (18.99%) receiving DMA prescriptions. The commonly prescribed DMAs were injectables (10.46%), followed by orals (6.06%) and infusions (2.40%). Multivariable logistic regression revealed that older adults between 60- to 64 years (Adjusted Odds Ratio [aOR]= 2.38) and 65-69 years (aOR=1.60) had higher odds of receiving DMA compared to older adults of 70 years and above. African Americans (aOR=1.71) had higher odds of receiving DMA prescriptions compared to Caucasians. The presence of symptoms (pain, fatigue, speech, walking difficulty) and use of symptomatic medication (anti-fatigue medication, bladder dysfunction medication, antispasmodics, antidepressants, and relapse medication) increased the odds of being prescribed DMAs. Multinomial logistic regression found that patients 60-64 years of age had higher odds of being prescribed infusion (aOR, 95% Confidence Interval [CI] =2.06, 1.35-3.15) and oral (65-69 years: aOR=1.60, 1.24-2.07) over injectable DMAs compared to the older adults aged 70 years and above.Older males (aOR=1.68, 95% CI: 1.23-2.30) were associated with increased odds of being prescribed infusion DMA over injectable DMA compared to females. The presence of comorbidities such as coagulopathy and peripheral vascular disorders decreased the odds of being prescribed oral DMA over injectable DMA. Patients with cerebellar symptoms had an increased likelihood of being prescribed with an infusion DMA over injectable DMA. Patients using drugs for treating relapses had higher odds of being prescribed an infusion DMA over an injectable DMA. In terms of healthcare utilization, older adults with outpatient visits had higher odds of being prescribed an infusion DMA over an injectable DMA, while older adults with inpatient visits had lower odds of being prescribed an infusion DMA over an injectable DMA.Nearly one in five older adults with MS are prescribed DMAs, with a majority receiving injectable DMAs. Several demographic and clinical factors were associated with DMA prescribing . This study fills the data gap regarding the utilization of DMAs in older adults with MS." @default.
