North American survey of hydrotherapy in modern burn care.

To investigate the role of hydrotherapy in the treatment of patients with burns, a survey was conducted of the use of hydrotherapy in Canada and the United States as part of an intensive investigation into the causes of Pseudomonas aeruginosa infections in burn injury. Results of the survey conducted indicate that hydrotherapy continues to be an important part of burn wound care in most (94.8%) burn centers in North America. Of the burn centers that use hydrotherapy, 81.4% continue to immerse patients, 82.8% perform hydrotherapy on all patients with burns regardless of total body surface area, and 86.9% continue with hydrotherapy throughout the entire phase of the patient's hospitalization. Routine culturing of the hydrotherapy equipment is standard procedure in 49.7% of the units surveyed, and culturing of the water supply to the equipment on a regular basis is done in only 18.6% of those burn units regularly using hydrotherapy. Pseudomonas aeruginosa was identified as the most common, major cause of sepsis in 52.9% of the burn units surveyed, Staphylococcus aureus in 25.5%, and Candida albicans in 5.2%. This survey demonstrates the extensive use of hydrotherapy in North American burn units and the concern for serious infections in patients with burns from gram-negative organisms such as Pseudomonas species. With the increasing number of reports of Pseudomonas infections related to the use of hydrotherapy equipment, the importance for further investigation into burn wound care with and without hydrotherapy, infection rates, and cost analysis appears to be indicated.
