Physician‐Reported Facilitators and Barriers for Side Effect Management of Heart Failure Medications

Abstract

Background Physician underprescribing and patient nonadherence are major barriers to the benefits of guideline‐directed medical therapy. An important contributor to both underprescribing and patient nonadherence is concern about medication‐related side effects. Yet, there are few to no data on approaches used by physicians to: (1) elicit medication‐related side effects, (2) attribute these side effects to specific medications, and (3) take appropriate action. Methods and Results The authors conducted semistructured interviews with physicians to identify facilitators and barriers to each critical step of heart failure medication management: elicitation of side effects, attribution of side effects to a medication, and action in response to attributed side effects. Interviews were transcribed and coded using directed content analysis. For elicitation of potential side effects, limited patient communication and family discordance in reporting were key barriers, whereas guiding questions, measurement, and open channels of communication were key facilitators. For attribution of side effects, confounding from other medications, limited time for clinical encounters, and nonspecific symptoms were key barriers, whereas time‐limited medication discontinuation trials and medication rechallenges were key facilitators. For taking action, challenges with weighing risks and benefits and physician fear about causing harm or interfering with other clinicians were barriers, whereas patient‐physician communication and the results of a medication discontinuation trials and medication rechallenge were facilitators. Conclusions This study generated key facilitators and barriers to 3 key aspects of heart failure medication management related to side effects that should drive future work to improve heart failure medication management.
