Introduction :
Pressure Injury (PI) is one of the recognized nursing outcome indicators and represents clinical effectiveness in bedside nursing. In 2015, 532 patients admitted to a medical rehabilitation care setting had community acquired stage I PI and 37% (N=195)of them had PI developed over the sacral area. There were 57% (N=111)of patient's PI either at recovering or healed upon discharge and 43% (N=84) were discharged with deteriorated or no change by using current care regimen. As there was no local reported study on the effects of silicone foam dressing in rehabilitation population and the hospital would like to enhance the PI care, CND thus took the lead in the study program with collaboration of clinical staff.
Objectives :
To evaluate the effectiveness of silicone foam dressing in reducing deterioration of community-acquired stage 1 sacral PIs on the size and healing of PI in rehabilitation setting.
Methodology :
It was a randomized controlled trial, based on random number to assign subjects to intervention group (IG) or control group (CG) via sealed envelope. Criterion sampling was adopted in subject recruitment. Adult patients who admitted with community-acquired stage 1 sacral PIs with Norton score < = 14 were recruited in the study. Patients with known allergy to silicone foam dressing were excluded from the study.
Result & Outcome :
Outcome measurement : (i) size of community acquired stage 1 sacral PI (ii) healing of community acquired stage 1 sacral PI after intervention.
Twenty four subjects were recruited with the recruitment rate 43%. Valid subjects:21,as 3 droped out,thus IG:9 and CG:12. Subject's age: 14% < 70 yrs and 86% >70 yrs, male: 8, female: 13. There were no statistical difference found between IG and CG on subject's sex, age, Norton Score and Albumin level. The mean rank of PI size of IG and CG were 11.22 and 10.83 respectively and there was no satistical signifcance found between groups. The mean PI size in IG and CG were 28mm and 21mm respectively. The comparison on mean PI size from Day 0 to Day of termination within IG and CG groups was found statistical significant with p=0.003 in IG and p=0.004 in CG respectively. For PI healing, there was no significant difference found between IG and CG as both groups showed 66.67% in subjects PI healing. The study concluded that both silicone foam dressing and a thin paraffin layer are equally effective in reducing the community acquired stage 1 PI from deterioration.
