Enhanced patient retention after combination vs single modality treatment using hyaluronic acid filler and neuromodulator: A multicenter, retrospective review by The Flame Group.

[BACKGROUND] It is believed that combination treatment with both neuromodulators (NM) and hyaluronic acid soft-tissue fillers (HA) results in superior aesthetic results and increased patient satisfaction compared to either treatment alone.

[AIMS] To determine whether combined treatment with NM and HA leads to greater patient retention than treatment with NM or HA alone.

[PATIENTS/METHODS] This is a large, multi-center, retrospective review of patient retention rates from 7 aesthetic practices across 5 continents, incorporating over 2600 patients. Patient retention is interpreted as a surrogate marker for overall patient satisfaction. Retention rates were compared at 1, 3, and 5 years for patients who received NM only, HA only, or combination treatment with both NM and HA.

[RESULTS] Combination therapy significantly increased the probability of retention for each time point (1, 3, and 5 years) compared with NM alone (P < .0001) and HA alone (P < .0001).

[CONCLUSION] This large multicenter, global retrospective review demonstrates that patients who received combined HA and NM were more likely to be retained in the same practice over many years than those who received either treatment alone.
