Wound Measurement Tools: A Comparison Guide for Post-Acute Care

Written by: Michael Fragala, PhD, MBA, RN, WCC, CSPHP, AMS

Post-acute care providers are constantly looking for ways to improve their quality of care. One such way is by using the right wound measurement tools. By utilizing the correct tools, providers can accurately measure, track, and monitor the healing progress of a wound.

In this guide, we compare different wound measurement tools and highlight the pros and cons of each method. We will also look at what quality treatment looks like and the potential outcomes that can be achieved. Finally, we will discuss why positive wound outcomes are important to the facility beyond patient healing.


The Importance of Accurate Wound Measurement

Accurate wound measurement is essential for the successful management and treatment of wounds in post-acute care. To effectively monitor healing progress, compare treatments, or decide on a course of action, wound measurements must be precise and consistent.

Measurements provide important data that helps caregivers determine if a wound is responding to treatment, if the wound is increasing in size, or if any further intervention is necessary.

Incorrect measurements often lead to incorrect treatment decisions, triggering wound complications that result in longer healing times. In the short term, inaccurate wound measurements can result in wasted resources, inadequate care, and frustration from both the caregiver and the patient. In the long term, inaccurate assessment  can increase the risk of infection and scarring and cause financial losses due to increased length of stay or readmissions.

Outside of patient healing, having accurate wound measurements also helps post-acute care facilities assess their performance by tracking the average time it takes to heal a wound, determining where there’s room for improvement, and analyzing their performance metrics over time. This also helps facilities better manage their costs by reducing supply usage and preventative measures such as decreasing the number of readmissions.

Overall, digital wound imaging tools enable facilities to deliver improved quality outcomes with fewer additional resources needed.

Common Challenges with Measuring Wounds

One of the most common challenges is measuring the size, depth, and healing progress of wounds. It can be time-consuming, inaccurate, and easily misread by clinicians due to its subjective nature.

Other common challenges include taking accurate measurements of wounds in areas with restricted access. This can be particularly tricky when measuring wounds in elderly patients or those with limited mobility. Similarly, caregivers may face difficulties when measuring wounds located in dark or highly vascularized areas of the body.

Obtaining accurate and consistent wound measurements can also be difficult when multiple providers treat patients. In many cases, one caregiver may document a wound measurement differently than another, resulting in discrepancies in the data and possibly delaying the healing process.

As such, it is essential for post-acute care providers to have access to accurate and reliable tools that can help them measure wounds quickly and efficiently. By leveraging digital imaging, caregivers can ensure that all their wound measurements are accurate and consistent, thus providing better patient care.

Traditional vs. Modern Wound Measurement Tools

Traditional wound measurement tools and methods, such as tracing sheets and paper rulers, have been used in healthcare for many years. Though they are reliable methods, they can be labor-intensive and inaccurate due to human error. In comparison to traditional methods, digital wound imaging offers several advantages.

Digital imaging systems can take multiple images of the wound to track the healing process more precisely. These systems also have built-in measurements that provide more accurate and consistent  data than manual methods.

Method: Tracing Sheets

PROS: Tracing sheets are cost-effective and can be used to accurately measure the perimeter of a wound. They are especially useful when measuring irregularly shaped wounds.

CONS: The accuracy of the wound measurements taken with tracing sheets is questionable. These measurements are subject to human error and can often be inaccurate. Also, the paper can tear, making it difficult to accurately track the wound size changes.

Method: Paper Ruler

PROS: Paper rulers are a low-cost, easy-to-use method of measuring wounds. They can quickly measure the area and approximate dimensions  of a wound.

CONS: Paper rulers are not precise and cannot capture the full dimensions of a wound or accurately measure irregular shapes. They also cannot measure depths and cavities without use of additional supplies ie. cotton tip applicator, complicating complex wound measurements.

Method: Digital Imaging

PROS: Digital imaging systems allow for quick, accurate, and consistent wound measurements that capture the full dimensions of a wound. These systems can capture high-resolution images and videos of wounds with depth information. Images taken with digital devices can be stored electronically for later analysis and comparison. It also reduces the risk of human error and provides a more accurate representation of the wound size. Fluorescence images give the added benefit of detecting antimicrobial growth to aid in proper assessment.

CONS: Digital imaging systems require upfront hardware, software, and training investments. Depending on the system, there may also be costs associated with ongoing maintenance, storage, and upgrades.

Conclusion: The Advantages of Digital Wound Imaging

Regarding wound measurement tools, digital imaging offers an accurate, efficient, and cost-effective solution for post-acute care providers. Digital imaging allows clinicians to accurately and objectively measure wounds, track healing progress, and document results in real time. This reduces the chances of human error when measuring a wound and ensures that data is consistently tracked and reported.

study of fluorescence imaging has shown that using digital imaging for wound healing has proven to be an effective tool. Over the course of 12 weeks, digital imaging showed a 23% increase in wound healing rate, a 33% decrease in antibiotic prescribing, and a 47% decrease in antimicrobial spending per wound.

This demonstrates the effectiveness of digital imaging in helping to promote wound healing and decrease the need for antibiotics and antimicrobial spending. These results show the value of digital imaging in wound care and its potential to revolutionize the medical field.

Digital imaging provides a host of quality treatment benefits that can help improve outcomes for patients. Quality treatment includes more frequent monitoring, better visualization of the wound, and improved communication with other healthcare professionals. It can also help reduce pain and anxiety associated with wound treatments.

Ultimately, the benefits of the proper wound measurement tools enable more effective healing and help post-acute care facilities reduce costs associated with wound management.
