“…If the deception is successful, providers' normal method of practice can be observed (Madden et al, 1997). Research using 'mystery shoppers' with pharmacists providing EHC has identified gaps in knowledge among dispensing pharmacists, and/or a failure to discuss ongoing contraceptive methods; this has been demonstrated in Australia (Hussainy et al, 2015;Higgins and Hattingh, 2013;Queddeng et al, 2011), the United States (Wilkinson et al, 2012;French and Kaunitz, 2007;Nelson and Jaime, 2009;Bennett et al, 2003;Sampson et al, 2009;Cleland et al, 2016;Gaffaney et al, 2016;Bullock et al, 2015), Canada (Cohen et al, 2004), Thailand (Ratanajamit and Chongsuvivatwong, 2001;Ratanajamit et al, 2002), Kenya (Liambila et al, 2010), Brazil (Tavares and Foster, 2016), and the United Kingdom (Glasier et al, 2010;Brant et al, 2014). Mystery shopper techniques have also identified other gaps in service provision, for example that EHC is more likely to be procured immediately from an urban than a rural pharmacy in California (Sampson et al, 2009), and Kansas (Samson et al, 2013), and by an English speaker more successfully than a Spanish speaker in California (Sampson et al, 2009).…”
