Category: Other Introduction/Purpose: Several researches focused on patient reported outcomes (PROs), however, little is known about the actual correlation between the patient satisfaction and PROs. The present study is to determine the correlation between patient satisfaction and PROs. Methods: A total of 35 patients with foot and ankle disability participated in this study to complete the data in terms of the patient satisfaction score and PROs. All of them were treated by a single foot and ankle surgeon. The Thai patient satisfaction score or Foot and Ankle Satisfaction Score [FASS] (0 [worst] -100 [best]) consisted of 4 items regarding patient’s perspectives as 1) symptoms, 2) function, 3) other complaints, and 4) recommendation of his/her treatment for other patients. PROs measures consisted of validated Thai visual analogue scale foot and ankle (VASFA) (0 [worst] -100 [best]) and Thai Short Form-36 (SF-36) (0 [worst] -100 [best]). Results: Mean total FASS was 92.0 ± 11.8, 87.7 ± 17.0, 98.6 ± 6.0, 98.6 ± 8.5 and for the items: symptoms, function, other complaints, and recommendation of his/her treatment for other patients, respectively. Mean total FASS was 94.2 ± 6.8. Mean VASFA was 67.7 ± 18.3. Mean SF-36 was 82.7 ± 10.7.There were no significant correlations between mean total FASS and PROs (VASFA [p-value < 0.05], SF-36 [p-value <0.05]). There were no significant correlations between mean FASS in all items and PROs (VASFA, SF-36) with all p-values < 0.05. The significant correlation was found between VASFA and SF-36 (Pearson correlation coefficient = 0.734; p-value<0.01). Conclusion: One of the successful treatment results is the improvement of patient satisfaction. Even if several researches focused on the assessment of PROs to achieve the successful outcome, this kind of measures was no significant correlation with patient satisfaction. PROs were not able to reflect the patient satisfaction following treatments. Patient satisfaction may be related to other parameters, in addition to the PROs, such as the patient expectation, the post-treatment level of physician-patient relationship, the patient’s confidence in his/her physician capability, etc. Further study is needed to clarify these factors.
