Objective: Quantify the incremental clinical and humanistic burden of advancing Parkinson’s disease (PD) in patients meeting the “5-2-1” criteria.
Background: The burden of PD worsens with disease progression [1], however the lack of objective and uniform disease classification challenges the understanding of the incremental burden in patients with advancing disease and suboptimal oral medication control. “5-2-1” is objective criteria recently proposed by clinical consensus to identify advancing PD, and have also demonstrated diagnostic accuracy [2,3].
Method: A retrospective analysis of multi-country (G7 countries i.e. US, UK, Germany, France, Italy, Spain, Japan) Adelphi Parkinson’s Disease Specific Programme (2017-2020) dataset was conducted. Device-aided therapy (DAT) naïve PD patients, currently on oral PD therapy were included. Patients meeting the “5-2-1” criteria were identified where “5-2-1” criteria was defined as having one or more of the 3 consensus clinical indicators of advancing PD: (i) Taking ≥5 doses of oral levodopa per day, OR (ii) Having off symptoms for ≥2 hrs of waking day, OR (iii) Having ≥1 hr of troublesome dyskinesia. Incremental clinical, humanistic, and economic burden was evaluated in the “5-2-1” group compared to the “non-5-2-1” group. Wilcoxon-Mann-Whitney, t-test, chi square, and Fisher’s exact tests were used to compare the two groups as appropriate.
Results: From the analytic sample (n=4853), 32% patients met the “5-2-1” criteria. Compared to “non-5-2-1” group, patients with “5-2-1” had significantly higher clinical, economic and humanistic burden [Table 1]. In particular, the patients with “5-2-1” had: (a) ~1.5x times more comorbidities, (b) ~4x higher 12-month hospitalization rate, (c) ~3x higher duration of professional and non-professional caregiver use/week. The “5-2-1” patients had significantly lower quality of life and had ~2x more caregivers reporting moderate-to-severe burden.
Conclusion: PD patients identified using the “5-2-1” criteria demonstrated significant incremental clinical, humanistic and economic burden. Future research should evaluate the potential impact of timely DAT initiation in alleviating PD burden of patients meeting the “5-2-1” criteria.
