Simplified noncultured autologous cell grafting for the treatment of chronic nonhealing ulcers: the six-well plate technique

The financial and quality-of-life cost to patients living with a chronic wound in the community

Chronic wounds are associated with financial and personal costs. The system level expense associated with chronic wounds has been established, however, the out-of-pocket cost incurred by individuals who self-fund has not been the focus of extensive investigation. Recently, there has been renewed interest in evaluating quality of life, in line with the shift to patient enablement and self-care in chronic disease management. The objectives of this research were to describe the out-of-pocket wound treatment costs and the quality of life of people who have chronic wounds. A questionnaire incorporating the Cardiff Wound Impact Schedule and purpose-designed instruments was completed by a non-probability, convenience sample of 113 people in Australia and Wales. Data was analysed using descriptive statistics. The sample was on average 63·6 years of age and had wounds that were on an average 109 weeks duration. Participants had spent on average AU$2475 on wound dressing products since the wound started, and AU$121·82 in the most recent 28 days which represented 10% of their disposable income. Health-related quality of life was sub-optimal, 6/10 (ave) according to the Cardiff Wound Impact Schedule. Younger participants reported significantly poorer quality of life on all CWIS sub-scales when compared to older participants. This study found that chronic wounds present a significant financial cost to individuals who must self-fund their wound dressings and other wound treatment related expenses. Participants who had access to wound product subsidisation also experienced personal financial costs. People who have chronic wounds experience sub-optimal quality of life therefore this condition is also costly to the individual's well-being. The quality of life of younger people has not received adequate attention and requires further consideration given the many years that younger people may have to live with this debilitating and often recurrent condition. Continued action is required to reduce the financial and personal costs experienced by people who have chronic wounds. It is imperative that healthcare funding is directed to people who have chronic wounds, in particular to alleviate the out-of-pocket costs experienced by self-funders. Continued attention to the quality of life of people who have chronic wounds is required to minimise the negative effects of this condition and enhance well-being.

Autologous epidermal cell suspension: A promising treatment for chronic wounds

BACKGROUND

Chronic wounds have become an increasing medical and economic problem of aging societies because they are difficult to manage. Skin grafting is an important treatment method for chronic wounds, which are refractory to conservative therapy. The technique involving epidermal cell suspensions was invented to enable the possibility of treating larger wounds with only a small piece of donor skin. Both uncultured and cultured autologous epidermal cell suspensions can be prepared and survive permanently on the wound bed.

METHODS

A systematic search was conducted of EMBASE, Cochrane Library, PubMed and web of science by using Boolean search terms, from the establishment of the database until May 31, 2014. The bibliographies of all retrieved articles in English were searched. The search terms were: (epithelial cell suspension OR keratinocyte suspension) and chronic and wound.

RESULTS

From the included, 6 studies are descriptive interventions and discussed the use of autologous keratinocyte suspension to treat 61 patients' chronic wound. The various methods of preparation of epidermal cell suspension are described. The advantages and shortcomings of different carriers for epidermal cell suspensions are also summarised. Both uncultured and cultured autologous epidermal cell suspensions have been used to treat chronic wounds.

CONCLUSION

Although the limitations of these studies include the small number of patient populations with chronic wounds and many important problems that remain to be solved, autologous epidermal cell suspension is a promising treatment for chronic wounds.
