Introduction:
Patient-reported outcome measures have widely been used in the field of orthopaedics to determine treatment outcomes; however, they may not always align with the patient's goals for improvement following treatment. Therefore, we introduced the concept of patient-defined outcomes (PDOs): pretreatment goals or activities patients wish to improve following treatment, along with the patient-perceived difficulty and importance of these activities. This study aimed to evaluate PDOs in adults with hip dysplasia across 3 age groups while assessing patient variables for potential associations with choosing specific categories of activities.
Methods:
We analyzed PDOs in 180 adults diagnosed with hip dysplasia, stratified into age groups: young adults (18-39 years), older adults (40-59 years), and senior adults (60 years or older). Patients listed at least 1 activity into the PDO questionnaire, followed by rating the difficulty and importance of the activity on a scale from zero to 10. PDOs were grouped into 6 thematic categories: sports, exercise, hobbies, activities of daily living (ADLs), work, and social engagement.
Results:
ADLs were the most common PDO reported across all age groups, increasing from 47.2% of young adults to 68.2% of seniors, while exercise-related goals were the second most common reported PDO. Age and body mass index significantly positively related with choosing an ADL as a PDO (p = 0.017). Age (p = 0.041) and Pain Catastrophizing Score (p = 0.042) significantly negatively related, while University of California Activity Score (p = 0.020) showed a significant positive relationship, with reporting an exercise as a PDO. Almost all patients reported patient-perceived importance at the highest levels.
Conclusion:
These findings underscore the impact hip dysplasia has on function, as most patients, regardless of age, expressed a desire to improve in basic ADLs. In addition, the importance levels of activities were consistently high across all age groups, highlighting the significance of aligning treatment goals with patient-centered outcomes.

01:11Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
