Wound Chronicity in Patient Populations

In the next 40 years, the United States population is expected to rise from 326 to 404 million people. Trends project that during this time period, the growth rate of those of retirement age will be much higher than that of the rest of the population. In fact, by 2035, people over 65 years of age will outnumber children for the first time in American history.

Research indicates that older adults are more prone to wound development and decreased healing efficiency. Because current wound care products cannot keep pace with rapid market growth, technology must bridge the gap between market demand and available health care dollars.

HBS's KollagenTM products give health care providers a strong technological foundation to meet current and future demands. KollagenTM products help the body's healing capabilities in a wide variety of wound environments and offer the highest standard of care.
