RESUMO
Peripheral catheter dressing use is common but information about cost-effectiveness remains limited. A prospective, descriptive 3-month study was conducted to 1) assess the cost-effectiveness of two dressings used for peripheral venous catheters and 2) identify statistical associations between the effectiveness variables and the patient's gender and age, category of the professional involved in care, and length of time the dressing was in place. The study was conducted among a homogenous sample of 120 adult patients; the majority (71/59.2%) were women, mean age 54.5 (+/- 18.8) years. All catheters were inserted in the surgical unit of the University of São Paulo Hospital: 54 traditional (microporous tape) and 66 transparent film dressings were applied. Clinical effectiveness was defined as dressing adherence and the absence of complications. Cost effectiveness was assessed using incremental analysis and potential statistical associations. The measured outcomes are expressed in terms of the cost per unit/patient of success or effect. Traditional dressings were found to have a lower total cost ($12.53) but were less adherent (P <0.001) compared to film dressings. The rate of complications in each group was similar. Results confirm that traditional dressings may be used for short-term use catheter care (approximately 3 days); whereas, film dressings may be more cost-effective for longer-term use. Larger studies assessing the cost-effectiveness of various dressings to secure longer-term use catheters are needed.
