Adverse symptoms of immunosuppressants: A survey of Canadian transplant clinicians.

Adverse symptoms of immunosuppressants (ASI) impact quality of life (QOL) in solid organ transplant recipients; however, standardized approaches for active ASI surveillance and intervention are lacking. While management is highly clinician dependent, clinician views remain largely unexplored. We surveyed Canadian Society of Transplantation members on their perceptions of ASI including frequency, perceived QOL impact, causal attribution, management strategies, and success. Sixty-one clinicians participated in the survey of 12 ASI (tremor, diarrhea, nausea, constipation, dyspepsia, insomnia, edema, dyspnea, arthralgia, acne, mouth sores, paresthesias), for a 22% response rate. Forty-nine completed the survey (80% completion rate). Diarrhea, dyspepsia, and insomnia were most frequent, requiring management in ≥ 2% of patients by 96%, 90%, and 82% of respondents, respectively. Diarrhea, insomnia, and dyspnea were deemed to have an important QOL impact by 92%, 82%, and 69%. Immunosuppressants were universally implicated as causative of tremor, diarrhea, acne, and mouth sores. Over 80% reported success in managing mouth sores, dyspepsia, and constipation. Management strategies included adjustment of immunosuppressant or other medications, drug therapy, and nonpharmacologic approaches and varied according to perceived causal attribution. More study is needed to compare clinician and patient views. These results will be used to establish priorities for further investigation of ASI.
