Is WOMBAT the right tool for me?

The WOMBAT tool may be of benefit to you if you are seeking to undertake a direct observational study, particularly to quantify aspects of work and workflow. The use of WOMBAT as a reliable method for quantifying work continues to grow. WOMBAT has been used by research teams from several countries, including: Australia, United States, United Kingdom, Canada, New Zealand, South Africa, Italy, Finland, Sweden and Norway.

WOMBAT allows researchers to design their own data collection templates that can be tailored to answer a particular research question, or to focus on the work of a specific professional group. Thus, WOMBAT affords the ability for researchers to undertake observational studies of different health professionals in different settings and to answer a wide range of questions using a rigorous approach. Examples include:

  • examining hospital ward nurses’ time in medication related tasks [1] and interruptions during medication related tasks [2, 3]
  • assessing hospital doctors’ and nurses’ patterns of work and communication [4, 5] and measuring the impact of health information technologies [6-10]
  • quantifying how and with whom doctors on hospital wards spend their time [11]
  • examining intensive care unit nurse workflow during shift change [12]
  • quantifying the work patterns of doctors in intensive care units [13-16]
  • assessing the rate of interruptions and multitasking by intensive care doctors and nurses [17-19]
  • investigating work patterns, interruptions and multitasking in surgical wards [20, 21]
  • measuring the work patterns of hospital pharmacists’ [22, 23] and the impact of electronic medication management systems [23-25]
  • examining pharmacists’ workflow in community pharmacy [26]
  • quantifying work and interruptions experienced by nuclear medicine technologists [27]
  • quantifying junior doctors’ work practices after hours and on weekends [28, 29]
  • evaluating the impact of a drug monitoring system on nurses’ work in ambulatory care [30]
  • assessing interruptions and multitasking by doctors in emergency departments [31-35] and their impact on prescribing errors [36]
  • examining work patterns and the use of electronic health records in ambulatory care [37]
  • quantifying renal dietitians’ time [38]
  • examining medication management work processes of nurses in home healthcare [39]
  • assessing hand hygiene in birth attendants [40].

Alternatively, researchers can elect to use data collection templates, as applied in previous studies, to allow findings from different studies to be compared. One of the greatest advantages of using the WOMBAT tool is the potential to compare your findings with other WOMBAT studies. Thus, we suggest that, where possible, you consider using existing definitions of work tasks which will allow you to compare your findings with those from other WOMBAT studies. WOMBAT also provides the opportunity to undertake multi-site and cross-country studies.
