Feasibility of the intervention
Feasibility is defined as the extent to which a new treatment or innovation can be successfully implemented in a given agency or setting.46 We assessed feasibility in terms of success in participant recruitment, retention, and participation rates. We reported earlier that we successfully recruited 60 of 62 eligible patients and completed the intervention in 56 of the 60 enrolled. In addition, we were able to complete all components of the intervention by telephone or in person within the 12-month intervention window. We examined associations between post-test measures and amount of contact between patients and the TN, but only a few significant associations were noted. Having more in-person visits (r=.32; p=.015) and having fewer telephone contacts (r= -.38; p=.003) both were correlated with higher post-test TRAQ appointment keeping scores, but contact time was not associated with any other TRAQ subscales, SCD knowledge, or pain management scores at post-test. As might be expected, more contact time was required by those with less confidence in managing SCD (r= -.29; p=.03) and those with higher disease frustration (r=.31; p=.02) and medication barriers (r=.28; p=.04) scores on the AMBS.
