Arch Phys Med Rehabil 2000;81:1110-6. Objective: To investigate two methods of wound measurement (planimetry and digitizing) performed on two routinely used techniques of clinical wound assessment, tracings taken directly from a patient's wound (raw tracing) and from photographs of the wound (photographic tracing). Design: We examined the level of repeatability and thus reliability of these methods, and determined if absolute measured wound size differed between the combinations of method and assessment procedures. Patients: Seven patients (4 women, 3 men; mean age ± standard error of the mean=63.1 ± 5.0yrs) with a total of 11 wounds. Setting: Patients attended a podiatry outpatient department on two separate days for raw and photographic tracing of their wounds. For both of these trace types, a series of repeated recordings were conducted by a single investigator using planimetry and digitizing measurement methods. Main Outcome Measure: Independent statistical analyses (analysis of variance, p Results: Planimetry produced a significantly larger degree of variability (thus less repeatability) than digitizing ( p = .02) and also produced smaller readings ( p = .00001). Averaging over methods also indicated that photographic tracings produced smaller readings than raw tracings ( p = .019). Conclusion: For the wound sizes and shapes examined, tracings taken directly from the patients were found to be an inexpensive clinical and research assessment tool on which digitizing was conducted with a higher level of repeatability than planimetry. Further research is needed to determine if the current findings apply to a wider population within wound management clinics. © 2000 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation |
