Algorithm 1.

Trip

1	Input: 𝒪, λ, ω, μ
2	Initialize ${\mathbf{A}}_k^{(n)},{\mathbf{H}}_k^{(n)}$, Y(n).
3	repeat
4	// Update patient mode n = 1
5	Hospitals set ${\mathbf{A}}_k^{(1)}\forall k$ (Eq. 7).
6	for n = 2, …, N do //Update feature modes
7	Hospitals set and send ${\mathbf{A}}_k^{(n)}\forall k$ (Eq. 9).
8	Server sets and sends A(n) (Eq. 10).
9	Server sets B(n) and Y(n) (Eq.11, 12).
10	Hospitals set and send ${\mathbf{H}}_k^{(n)}\forall k$ (Eq. 13).
11	end for
12	until Converged
