For patients receiving anticoagula- tion therapy for treatment of VTE, the ASH guideline panel suggests against using a daily lottery (between a 1-in-5 and 1-in- 100 chance of a monetary reward each day if a pill compartment on a sophisticated electronic-medication-monitoring system is accessed) to improve medication adherence (conditional rec- ommendation based on very low certainty in the evidence about effects ). Recommendation 13b. For patients receiving anticoagulation therapy for treatment of VTE, the ASH guideline panel suggests against using electronic reminders (daily alarm via an electronic- medication-monitoring system) to improve medication adherence (conditional recommendation based on very low certainty in the evidence about effects ). Remark: This recommendation applies specifically to a sophisticated alert system used in the study evaluated by the panel. Recommendation 13c. For patients receiving anticoagula- tion therapy for treatment of VTE, the ASH guideline panel recommends against using a daily lottery (see recommendation 13a) plus electronic reminders (see recommendation 13b) to improve medication adherence (strong recommendation based on very low certainty in the evidence about effects ). Remark: This recommendation applies specifically to a sophisticated alert system used in the study evaluated by the panel. Recommendation 13d. For patients receiving anticoagula- tion therapy for treatment of VTE, the ASH guideline panel suggests against using visual medication schedules (pro- vided to patients at each visit, along with brief counseling) to improve medication adherence (conditional recommendation based on very low certainty in the evidence about effects ). Invasive procedure management Recommendation 14. For patients at low to moderate risk of recurrent VTE who require interruption of VKA therapy for invasive procedures, the ASH guideline panel recommends against periprocedural bridging with LMWH or UHF in favor of interruption of VKA alone (strong recommendation based on moderate certainty in the evidence about effects ). Recommendation 15.
