“…Whilst some APTs may restrict their role to the management of PCA and epidurals, others have a much broader remit, covering a variety of elements of post-operative pain management. Each of these elements of their remit have been purported to contribute to a more effective APS, and include staff training (Rawal, 1994b;Ferguson, 1995b;McLeod et al, 1995;Notcutt and Austin, 1995;Coleman and Booker-Milburn, 1996;Mackintosh and Bowles, 1997;Chen et al, 1998;Tighe et al, 1998), development of guidelines and protocols (Williams et al, 1991;Hall and Bowden, 1996;Humphries et al, 1997;Pesut and Johnson, 1997;Wong et al, 1997), introduction of algorithms to increase the effectiveness of IM analgesia (Gould et al, 1992), introduction of pain and sedation scoring systems (Wheatley et al, 1991;Gould et al, 1992;Rawal 1994aRawal , 1994bTsui et al, 1995;Mackintosh and Bowles, 1997;Tighe, et al, 1998), audit and research (Wheatley et al, 1991;Hughes and Rawal, 1994;Hall and Bowden, 1996;Watts, 1998;Rawal, 1999) and patient teaching and information-giving (Coleman and Booker-Milburn, 1996;Gabrielczyk and McGonagle, 1997;Mackintosh and Bowles, 1997). In some cases, as part of ongoing educational programmes, APTs have also established 'link nurse' systems, where a named nurse on each surgical ward is given additional training and responsibility in acute pain management, sometimes accompanied by an accredited qualification.…”
