Does patient self-care (PST or PSM) with at least weekly INR measurement improve INR control in patients on warfarin?
Patient self-care with at least weekly INR measurements is an effective strategy for controlling INR levels in patients taking warfarin.
Patient self-care (either PST or PSM) by measuring INR values at least once weekly is more effective in controlling the INR level.
