[Development of clinical performance indicators for establishing a connecting system between hospital performance management and quality improvement].

PURPOSE: This study aimed at developing integrated clinical performance indicators(CPIs) through the analysis of quality improvement(QI) activities of a hospital and literature review about performance measures. METHOD: The CPIs were developed through the following three stages; 1)Identifying preliminary CPIs 2)A staff validity test in preliminary CPIs 3)Developing final CPIs. RESULT: One hundred twenty-three preliminary CPIs were developed through QI activities of the target hospital for 8 years and literature review. The results of the validity test for the preliminary CPIs supported ninety-one items. Sixty-two CPIs were selected through integration, reclassification and renaming. Then, eighteen items were deleted on account of an imprecise calculation method. Finally, forty-four CPIs were confirmed. They consisted of twenty-six items at the hospital level and eighteen items at the department level. CONCLUSION: CPIs can be used as criteria to evaluate the performance of healthcare organizations, and to decide the quality of healthcare for customers. This study may contribute to establishing an integrated system between QI activities and performance measurement of healthcare organizations.

A surgical approach for earlobe keloid: keloid fillet flap.

Earlobe keloid can form after cosmetic ear piercing, trauma, or burns, and it poses several difficulties in treatment and distinctive cosmetic implications. Treatment methods for earlobe keloids include both surgical and nonsurgical methods. After excision of the earlobe keloid, healing by secondary intention, primary suture, skin graft, or local flap has revealed some disadvantages. The authors approached this problem with a new excision and covering method. The surgery was performed under local anesthesia. Skin over the keloid was dissected from the keloid mass as a flap, which they termed a "keloid fillet flap," and the keloid mass was completely removed. Subcutaneous sutures were not used, and the keloid fillet flaps were closed with 6-0 nylon sutures after trimming. Other intraoperative or postoperative preventive procedures, such as steroid injection, pressure device, or irradiation, were not applied primarily. In the period from May of 1999 to October of 2000, nine earlobe keloids in eight patients were treated with this protocol. One patient had bilateral keloids. Of the eight patients, there were six women and two men, ranging in age from 21 to 61 years (mean age, 28.5 years). The causes of keloids were ear piercing in six cases and trauma in three cases. The largest lesion was 3 cm in its greatest dimension, and the smallest was 1.5 cm (mean, 2.3 cm). All flaps survived completely. There were four cases of recurrence. Seven cases, including two recurrences, showed good results. The authors believe the recurrence of earlobe keloid was closely related to the method for coverage of the defect after its surgical excision, and the "5 As and one B" (Asepsis, Atraumatic technique, Absence of raw surface, Avoidance of tension, Accurate approximation of wound margin, and complete Bleeding control) are important factors in reducing the recurrence rate of earlobe keloids in surgical excision. The authors' protocol is very effective in closing the defect after surgical excision of earlobe keloids and offers many advantages over other surgical approaches. The recurrence rate of earlobe keloid may be lower than in their results if other intraoperative and postoperative treatment procedures are combined with their protocol.

Resurfacing of a totally degloved hand using thin perforator-based cutaneous free flaps.

Resurfacing after a total degloving injury to the hand is one of the most difficult management problems in hand surgery. Although there are many methods of managing this type of injury that preserve functions and lessen deformities, none provides a satisfactory solution to this problem. The authors resurfaced a totally degloved hand using extremely thin and broad perforator-based cutaneous free flaps, and the donor defects were covered with split-thickness skin grafts. The postoperative course was uneventful, the flaps survived completely, and the grafts took without loss. Several minor operations, including interdigitation, defatting, and the formation of palmar and digital creases, were required to obtain the final appearance and function of the hand. Eighteen months after the initial operation, the patient could pick up a bean with a pair of chopsticks. Sensation was satisfactory in the palm 20 months after the initial operation, as evidenced by 10 mm of static two-point discrimination. To reconstruct a total and complete skin defect of the hand, the authors recommend that thin perforator-based cutaneous free flaps be an initial consideration.

Correction of inverted nipple: an alternative method using two triangular areolar dermal flaps.

Inverted nipple, which is defined as a nipple located on a plane lower than the areola, presents both functional and cosmetic problems. It is a source of repeated irritation and inflammation, and interferes with nursing. In addition, its abnormal appearance may cause psychological distress. Inverted nipples are congenital or acquired, and are classified as the umbilicated and invaginated types or divided into 3 groups (grades 1, 2, and 3). With consideration of its underlying pathophysiologic components and severity, various surgical procedures have been proposed. For correcting the inverted nipple, the authors introduce an alternative, simple method using 2 triangular areolar dermal flaps. Compared with other methods using triangular areolar dermal flaps, each triangle is approximately 1 mm shorter than the diameter of the nipple, and the deepithelialized areolar dermal flaps are lodged at the slit in the bundle of the lactiferous ducts in the grade 2 inverted nipple. From August 2000 to December 2001, 11 patients (16 nipples) were treated. Five patients had bilateral inverted nipples. Patient age at operation ranged from 18 to 31 years (mean age, 27 years). All nipples were congenital and they had no previous operation. Thirteen nipples were grade 2 and 3 were grade 3 according to the classification of inverted nipple by Han and Hong. The mean follow-up period was 8.7 months (range, 3-12 months). Follow-up examinations revealed no evidence of recurrence of inversion. There was no complication associated with surgery, such as infection, hematoma, permanent sensory disturbance, or nipple necrosis. The resulting scars were minimal. All patients were satisfied with their results. The authors conclude that their procedure is reliable, preserves the lactiferous ducts in grade 2 inverted nipple, requires no special postoperative care, and leaves minimal scars and no recurrence of inversion. This technique can be applied to any type of inverted nipple as a primary surgical procedure.

Eyebrow island flap for reconstruction of a partial eyebrow defect.

A diverse variety of methods for reconstructing eyebrow defects has been described previously, and each procedure has inherent advantages and disadvantages. The authors present a case of reconstruction of a partial eyebrow defect using two eyebrow island flaps, which are modifications of the subcutaneous pedicle flap.
