Assessing a tool to measure patient functional ability after outpatient surgery

Area of Science:

• Medical assessment
• Patient outcomes
• Surgical recovery

Background:

• Assessing patient recovery and satisfaction post-outpatient surgery is crucial.
• Existing tools may not adequately capture functional ability 24 hours after discharge.
• The 24-Hour Functional Ability Questionnaire (24hFAQ) was developed to address this gap.

Purpose of the Study:

• To evaluate the validity of the newly developed 24hFAQ in the postoperative outpatient setting.
• To assess content, construct, discriminant, and criterion (predictive) validity of the 24hFAQ.
• To determine the utility of the 24hFAQ for measuring functional status and satisfaction.

Main Methods:

• Structured interviews were used preoperatively and up to 24 hours post-discharge.
• Validity was assessed using established criteria: content, construct, discriminant, and criterion (predictive).
• Response frequencies, interitem correlations, and relationships between clinical endpoints and satisfaction were analyzed.

Main Results:

• Content validity was supported by appropriate response distributions and minimal irrelevant responses.
• Construct validity was supported by strong correlations within cognitive and physical domains.
• Discriminant validity showed mixed results; key symptoms impacted satisfaction, but residence times did not. Criterion validity was supported.

Conclusions:

• The 24hFAQ demonstrates overall validity for assessing functional ability and satisfaction in outpatient postoperative populations.
• The questionnaire's content, construct, discriminant, and criterion validities support its utility.
• The 24hFAQ is a valuable assessment instrument for the outpatient surgical setting.
