“…Most of the Latin American studies available, some of which are comparative between countries [ 8 , 21 , 22 , 23 ], come mainly from Brazil [ 8 , 22 , 23 , 24 ], Mexico [ 21 , 22 , 25 , 26 ], and Colombia [ 8 , 21 , 22 , 23 , 27 ]. Likewise, very few of these study RC in a comprehensive way, with the majority focusing on analysing just one attribute of RC in PC—the consistency of the doctor [ 22 ], the doctor–patient bond [ 24 , 25 ], or communication with the doctor [ 27 ]—through either qualitative methods [ 27 ] or surveys of health services users [ 8 , 21 , 22 , 23 , 24 , 25 ] or people with social security in general [ 26 ]. Quantitative studies on chronic patients and SC doctors RC are extremely limited to date.…”
