Feasibility, acceptability, and efficacy of a proactive telephone intervention to improve toxicity management during chemotherapy.

Abstract

105 Background: Chemotherapy (chemo) is associated with a significant risk of toxicity, which often peaks between ambulatory visits. Consequently, effective remote symptom management support is essential to optimize self-management and resource use, including emergency department visits and hospitalizations (ED+H) during chemo. The aim of this study was to examine the feasibility, acceptability and effects of a telephone management intervention on symptomatic toxicity and resource use during chemo for early stage breast cancer (EBC). Methods: A prospective study of telephone-based toxicity management among women receiving neo-adjuvant or adjuvant chemo for EBC was undertaken at one urban and one rural site in Ontario, Canada. The intervention consisted of two standardized calls by nurses assessing common toxicities after each chemo (call 1 within 3 days and call 2 within 8-10 days). Primary outcome measures were feasibility and acceptability based on patient (pt) and clinician feedback. Efficacy was evaluated by self-reported ED+H. Results: Between 09/2013 and 12/2014, 77 women with EBC were enrolled (mean age 55 years). Most commonly used regimens were AC-paclitaxel (58%) and FEC-docetaxel (16%). 78% of pts received primary GCSF prophylaxis. Adherence with calls was 82%; mean call duration was 9 minutes. The intervention was well received by both pts and clinicians. 97% of pts indicated they liked receiving the calls and 94% would recommend this protocol be offered to all pts receiving chemo. Clinicians and pts felt the calls reduced pt anxiety by providing just-in-time education and counselling. Twenty five (33%) pts reported at least one ED+H during chemo, lower than the historical rate of 44% for this population in Ontario. Challenges included introducing an intervention that involved both routine clinical personnel and research staff and incorporating the calls into existing work responsibilities. Conclusions: Telephone-based toxicity management during ESB chemo is feasible, perceived as valuable by clinicians and pts, and may be associated with lower rates of acute care use. Larger scale evaluations of this approach focusing on effectiveness are warranted.
