Wound prevalence and healing times

The driving force in the market for surgical sealants, glues, wound closure and related products is simply the number of different wound and the need to optimize healing to minimize blood loss, infection and other sequellae, all of which otherwise add to the cost of healthcare.

The predominant form of wounds, by numbers, is surgical wounds; that is, those wounds caused by surgical incision, as opposed to trauma.  Given the formation of the wound, the surgical incision, in a carefully controlled manner that accordingly results in clean edges, little or no tissue loss, sterile conditions and other considerations, surgical wounds are most readily healed, typically in less than two weeks.  At the other end of the spectrum are chronic wounds, the majority of which are venous, arterial and diabetic ulcers, caused by inadequate blood flow, which is in turn caused by either excess pressure (e.g., "bed" sores) or conditions such as diabetes that are associated with occlusions in small blood vessels.

Below is illustrated the resulting scale, between wound prevalence and healing time, for the range of different wound types.  While surgical wounds are high in prevalence and may be expeditiously managed by conventional wound sealing and closure technologies, chronic wounds are much less prevalent, but the costs associated with their ongoing management in efforts to heal them create a big need for effective treatments.

  1. The healing time of 40 days for chronic wounds is generous at best.  Many chronic wounds (decubitus, stasis, and diabetic ulcers) have such extended wound healing times that most estimates leave “healing time” blank.  The purpose in putting in “40 days” in the above graph was to simply get the prevalence number to be shown on the graph.

  2.  If US Medicare and Medicaid is reporting 7-8M as the prevalence of chronic wounds per year, how is your worldwide estimation only 40M?  How did you estimate the prevalence of the 6.8B+ people, or is just a subset of the world? 

  3. First prevalence is a total current number for any given condition, while incidence is a rate over time. If indeed the incidence figure for Medicare and Medicard is 7-8M per year, then a worldwide prevalence of 40M is completely within the expected range.

  4. I would appreciate whether you could clarify my doubts about this data. Does this prevalence refer to 2011? I was wondering if it’s an estimate for 2017 or the current values of wound prevalence. Thank you very much.
