The impact of government-mandated shared decision-making for implantable defibrillators: a natural experiment.
This study examined the impact of the 2018 Centers for Medicare and Medicaid Services (CMS) mandate that patients considering implantation of an implantable cardioverter-defibrillator (ICD) for primary prevention of sudden cardiac death undergo shared decision-making (SDM) using a decision-aid. The authors surveyed patients who underwent implantation of a primary prevention ICD within the Emory Healthcare system between 2017-2019 (pre and post SDM mandate). Survey domains included decisional conflict, knowledge about the ICD, values-choice concordance, and engagement in decision-making. Of 101 patients who completed the survey, 45 had an ICD placed before the mandate and 56 placed after. No major differences were found between any of the survey domains. Patients with ICDs after the mandate were more likely to subjectively feel more informed about the benefits of the procedure but were less likely to be able to correctly identify the frequency of complications.

Shared decision-making for implantable cardioverter-defibrillators: policy goals, metrics, and challenges.
Researchers discussed shared decision-making for implantable cardioverter-defibrillators (ICDs), including the results from a case study implementing the shared decision-making mandate for ICDs, which involved providing patients with decision aids prior to or following the doctor consultation.

Joint shock/death risk prediction model for patients considering implantable cardioverter-defibrillators.
This study’s goal was to develop a joint shock/death risk prediction tool for patients who received implantable cardioverter-defibrillators (ICDs). Secondary analysis of patients was conducted as part of the SCD-HeFT trial (Sudden Cardiac Death in Heart Failure Trial). An illness-death regression model was applied for both ICD shocks and deaths. Among 803 ICD recipients, 430 (53.5%) did not receive an ICD shock or die, 206 (25.7%) received at least 1 shock but did not die, 113 (14.1%) died before receiving a shock, and 54 (6.7%) received at least 1 shock but still died. This predictive performance can be used as a tool for individualized counseling for patients contemplating an ICD.

Development and validation of a patient-centered knowledge scale for left ventricular assist device placement.
The authors presented a comprehensive and valid methodology for developing a clinically informed and patient-centered measure of knowledge about left ventricular assist device (LVAD) therapy to facilitate discussion and measure candidate understanding of treatment options. They concluded that the LVAD knowledge scale may be useful in clinical settings to identify gaps in knowledge among patient candidates considering LVAD treatment; to better tailor education and discussion with patients and their caregivers; and to enhance informed decision-making before treatment decisions are made.

Assessment of patients' and caregivers' informational and decisional needs for left ventricular assist device placement: implications for informed consent and shared decision-making.
The authors investigated the decision-making process and informational and decisional needs of patients and their caregivers regarding left ventricular assist device (LVAD) placement. They found that participants easily and clearly identified their values: life extension; family; and mobility. Participants reported the need to meet other patients and caregivers before device placement and to have an involved caregiver to synthesize information. They further found that some participants demonstrated a lack of clarity regarding transplant probability.
