To determine whether respondents also had generally negative or positive attitudes, we used <italic>K</italic>‐means cluster analysis. A‐TDM service providers were also surveyed.</p> </sec> <sec id="jppr1079-sec-0004" sec-type="section"> <title>Results</title> <p id="jppr1079-para-0004">From 145 junior medical officers contacted, 49 (33%) responded: 34 interns and 15 residents. The majority of officers provided generally positive responses, with 38 stating that they were aware of A‐TDM, 17 that it often assisted in their patient management, 34 that it improved optimal dosing, 22 that it improved duration, 32 that it improved toxicity minimisation and 33 that it improved their understanding of TDM principles. Cluster analysis produced a positive attitudes group (<italic>n</italic> = 35) and a negative attitudes group (<italic>n</italic> = 14) with significantly different responses for each of the six questions (p < 0.01 for each), indicating consistently different attitudes towards the service. Twelve of thirteen A‐TDM service providers responded: eight pharmacy and four medical, reporting positive attitudes towards A‐TDM on treatment efficacy (<italic>n</italic> = 11), dose optimisation (<italic>n</italic> = 11) and patient safety (<italic>n</italic> = 12).</p> </sec> <sec id="jppr1079-sec-0005" sec-type="section"> <title>Conclusion</title> <p id="jppr1079-para-0005">A significant proportion of respondents were aware of A‐TDM principles and demonstrated favourable attitudes towards its use for dose optimisation and for minimising toxicity.</p> </sec> </abstract>
