PURPOSE
S: The purpose of this study was to evaluate the extent of performance on activities in critical pathway (CP) according to eight domains and six admission days on nursing records of patients who received total hip replacement surgery.
METHODS
We reviewed 90 nursing records of patients who received total hip replacement surgery from June, 2004 to July, 2005 at C University Hospital. Data were collected using Hong's CP (2002) and were analyzed using ANOVA.
RESULTS
The domain of diet was valued the highest in CP performance scoring, followed by the domains of assessment, activities, and test. There were differences in the performance scores according to the period of admission in all of the domains. Among 132 activities in the CP, 18 activities were completely performed, of which most included activities belonging to the domain of assessment on the admission day. Twelve activities were never performed, of which most included activities belonging to the domain of treatment on the day of operation and the first day after operation.
CONCLUSIONS
Therefore, further studies on the development of a new system to increase CP utilization and on updating the contents of CP from the best practice based on evidence is recommended.

PURPOSE
The purpose of the study was to test the effects of music therapy on postoperative pain in patients with total hip replacement.
METHOD
The research design was a nonequivalent control group pretest-posttest design. The subjects were composed of thirty patients with total hip replacement. Fifteen of them were assigned to the experimental group and fifteen to the control group. Fifteen minutes tailored music therapy was given to the experimental group during five consecutive days. The instruments used for this study were pain NRS(numerical rating scale). The data were analyzed using percent, mean, standard deviation, chi-square-test and repeated measure ANOVA using SPSS WIN 11.0.
RESULTS
Hypothesis 1 "The score of pain NRS of experimental group will be lower than those of control group" was accepted(F=15.945, p<.001). Hypothesis 2 "The frequency of PCA analgesics of experimental group will be fewer than those of control group" was accepted (t=-2.312, p=.028). Hypothesis 3 "The vital signs(pulse, systolic BP and diastolic BP) of experimental group will be different from those of control group" was rejected.
CONCLUSION
This music therapy can be recommended as an efficient nursing intervention to reduce postoperative pain in patients with total hip replacement.
