3-hourly repositioning using 30º tilt overnight was cost saving (nurse time cost per patient €206.6 vs €253.1).


n The authors concluded that the lack of robust evaluations of repositioning frequency and position for PU prevention, while a source of uncertainty, do not mean that these interventions are ineffective because all comparisons are grossly underpowered.

n The authors investigated a multi-component educational programme, and conducted a secondary analysis of data, to examine relationships between health behaviours among people with a venous leg ulcer who participated in an e-learning programme.


n Relationships between various health behaviours following completion of an education programme were assessed; participants were receiving community nursing services, had a medically confirmed venous leg ulcer, and spoke English.


n The education package comprised six sessions that covered leg ulcer treatment and the role of compression therapy, being active and the conduct of leg exercises and leg elevation, healthy eating and hydration, skin care, and compression stocking and hosiery application aids.


n No significant differences were identified by participant gender, age or need for a carer. Participants performing few of the recommended health-promoting behaviours prior to the education achieved more behaviour change than those already engaged in the sought after activities (P=0.000).


n The authors concluded that, while people living with venous disease are encouraged to make multiple behaviour changes, there is limited association between the health behaviours recommended and those subsequently pursued.

A prospective, randomised comparative study of weekly versus biweekly application of


whether weekly application of dehydrated human amnion/ chorion membrane allograft for the treatment of diabetic foot ulcers reduced time to healing more effectively than biweekly application.


n Patients with non-infected ulcers (n=40) of ≥4 weeks’ duration were recruited and randomised to receive weekly or biweekly allograft application plus a non-adherent, moist dressing with compressive wrapping and offloading for the duration of the 12-week study period.


n Complete healing was achieved in 92.5% of ulcers during the study period; mean time to complete healing was 4.1±2.9 versus 2.4±1.8 weeks (P=0.039) in the biweekly versus weekly groups, respectively. By week 4, complete healing occurred in 50% of the biweekly group, and 90% of the weekly group (P=0.014). The total number of grafts applied was similar between the groups (2.4±1.5 vs 2.3±1.8 for biweekly vs weekly groups, respectively; P=0.841).


n The authors concluded that allograft is an effective treatment for diabetic ulcers and that weekly application heals wounds more rapidly than biweekly.

Comparative effectiveness of advanced wound dressings for patients with chronic venous leg


a a a a a a a a


n The authors undertook a systematic review of the literature on the benefits and harms of advanced wound dressings on wound healing, mortality, quality of life, pain, condition of the wound bed, and adverse events among patients with chronic venous leg ulcers, as compared with treatment with compression alone.


n Primary studies from January 1980 through July 2012 listed in online databases were collected and evaluated by two independent reviewers.


n Thirty-seven studies met the search criteria and were included. n Though most evidence was of low or insufficient quality, some suggested that cellular dressings, collagen, and some antimicrobial dressings may improve chronic venous leg ulcers healing rates when compared with compression alone or other dressing types.


n The authors highlighted the limited data available and concluded that, given the poor quality of the literature, well- conducted studies to evaluate the effectiveness of advanced wound dressings on chronic venous ulcer healing are needed in the future.
