Meetings were held over a three month period prior to commencing formal data<br />

collection with the nurse manager <strong>and</strong> CNS to gain insight into the graduate nurse<br />

orientation period <strong>and</strong> the daily operations <strong>of</strong> 6N. Additionally, the researcher<br />

received her own <strong>informal</strong> orientation <strong>of</strong> the unit as she spent several short periods <strong>of</strong><br />

time on the floor with the CNS. During these periods, the CNS introduced staff<br />

members, noting their title <strong>and</strong> <strong>role</strong> on the unit, <strong>and</strong> also commented on how staff use<br />

the space.<br />

2.6.1 Clinical Work Measurement (CWM) Tool<br />

<strong>The</strong> CWM tool, developed by the Health Informatics Research & Evaluation<br />

Unit (HIREU) at <strong>The</strong> University <strong>of</strong> Sydney in Australia, uses multi-dimensional work<br />

classifications for measuring the work patterns <strong>of</strong> doctors, nurses <strong>and</strong> pharmacists.<br />

<strong>The</strong>se classifications are programmed into h<strong>and</strong>-held PDAs equipped with specially<br />

developed s<strong>of</strong>tware. An observer follows individual clinicians for periods <strong>of</strong> up to 2<br />

hours as they undertake their daily work tasks. During this time, a PDA is used to<br />

collect information about work tasks (eg. what they are doing), as well as information<br />

about who is involved in the task <strong>and</strong> how the task is being completed (eg. with a<br />

telephone, computer, etc). Additionally, the tool allows the observer to capture<br />

interruptions <strong>and</strong> multi or parallel tasking as well as the distribution <strong>of</strong> clinicians’ time<br />

across work tasks.<br />

A major purpose <strong>of</strong> the study was to investigate ways in which the <strong>physical</strong><br />

layout <strong>of</strong> the unit affects interaction patterns, yet the original CWM program was not<br />

<strong>design</strong>ed to collect data on the location <strong>of</strong> interactions. Consequently, the existing<br />

pre-programmed “how” category, which recorded information on how the task was<br />

executed, was replaced with a “location” category (see Appendix D for modified<br />

categories). This change allowed the researcher to record where on the unit each<br />
