Online Crowdsourcing Survey of United States Population Preferences and Perceptions Regarding Outpatient Hip and Knee Arthroplasty



      Outpatient total joint arthroplasty (TJA) has been shown to be both safe and cost-effective in appropriately selected patients and continues to expand substantially across the United States. Using online crowdsourcing, we aimed to assess population perceptions regarding outpatient TJA and to determine factors associated with preference for outpatient versus inpatient arthroplasty.


      A closed-ended survey consisting of 39 questions was administered to members of a public platform. Study participants responded to questions regarding demographic factors and outpatient TJA. Validated assessments to capture health literacy and engagement were also used. To determine factors associated with preference for outpatient TJA, multivariable logistic regression analyses were performed.


      In total, 900 participants completed the survey. After exclusion of surveys with incomplete data, 725 responses remained for analysis (80.6%). Over half (59.9%) of the survey participants would feel comfortable going home the same day of surgery following TJA. However, two-thirds (64.6%) would prefer to stay in the hospital following TJA. The majority (68.0%) of respondents perceive a hospital setting as the safest location for TJA. The 3 major concerns regarding outpatient TJA were cost, post-operative pain control, and post-operative complication. Among the 111 respondents (15.3%) who would prefer outpatient TJA, 45% would pay more out-of-pocket, 63.1% travel further, and 55.9% would be willing to wait longer to have their surgery performed as an outpatient. On multivariable regressions, those living in a suburban setting (adjusted odds ratios, 95% confidence intervals: 4.2 [1.3-2.7], P = .02) and >60 year old adjusted odds ratios (95% confidence intervals: 8 [2-33.1], P = .004) were more likely to prefer outpatient TJA.


      Despite the rise in outpatient TJA, the majority of the public appears to prefer inpatient TJA and the minority would expect to be discharged home the same day. Our data can be used to address specific patient concerns regarding outpatient TJA and set realistic expectations for hospital systems and ambulatory facilities.
