“…Table 1 shows a description of the scope of practice as reported in the included studies. The definition of the scope of practice was explicitly reported in six studies [22-25, 28, 31], and covered the dimensions of scope, such as clinical procedures [22][23][24]28], clinical practices [25,28,31], clinical and nonclinical activities [24,30], and practice settings [25,28]. It was self-reported in nine studies [20, 21, 23-26, 28, 30, 31], or reported with objective measures (e.g., direct observation or administrative database) in two studies [22,27], with a mixed approach (subjective and objective measures) used in one study [29].…”
