Abstract titles should be brief and reflect the content of the abstract.
We evaluated the impact of digital care pathways (dig-CPs) on healthcare utilization (HCU) of ANCA-associated vasculitis (AAV) patients. Dig-CPs integrate AAV-specific, risk-stratified pathways with remote monitoring of patient reported outcomes (PROs) on quality of life and disease symptoms. A nurse practitioner triages PROs daily to guide timely clinical interventions.
Dig-CP technology of DEARhealth was implemented as standard of care for AAV patients in late 2022 at the Nephrology outpatient clinic. Alongside a remission induction pathway, three risk-based maintenance pathways were introduced (high, medium and low risk). We analyzed contacts with healthcare providers (HCP) between January 2022 and May 2025, examining associations with dig-CP usage and PRO outcomes. PROs included the patient global assessment of disease activity (PGA; 0-10) and the AAV-PRO questionnaire (0-100%, based on 29 questions scored 0-4).
Of 199 AAV patients in care, 115 (58%) used dig-CPs and 84 (42%) did not. A total of 260 dig-CPs were initiated, mostly maintenance pathways (44% high risk, 26% medium risk, 17% low risk). Frequency of HCP contacts correlated strongly with the assigned risk-profiles (p<0.001).
Average annual HCP contacts per patient declined from 6.5 in 2022 to 5.7 in 2023 and 5.5 in 2024. This decline was solely driven by reduction among dig-CP users (p=0.02), while no change was observed in non-users (p=0.32). Nurse practitioner involvement was also significantly higher among dig-CP users (21% of contacts), compared to non-users (5%) (p=0.01).
Moreover, poor PRO scores predicted increased HCU (≥3 contacts) in the next three months, with odds ratios up to 5.1 [IQR 2.7–9.9] for PGA scores of ≥7 and 4.7 [IQR 2.8–8.0] for AAV-PRO scores of >40%.
Dig-CPs effectively reduced outpatient contacts and facilitated care transition to nurse practitioners. They also enable early identification of patients at risk for increased care needs, enabling proactive interventions.
