Brief Summary:
This study evaluates a technology-enabled decision aid that provides evidence-based education (i.e. on understanding the condition, treatment options and comparisons, patient values and question & answer quiz) and personalized, quantifiable benefit-risk ratio alongside the level of potential benefit in relation to joint stiffness, joint pain and quality of life. The study will be performed in the setting of an integrated care system providing patient-centered care for hip and knee osteoarthritis over the full cycle of care. The impact of a technology-enabled decision aid incorporating predictive analytics with machine learning capabilities on decision quality, activation, experience & limitations of patients in this setting is relatively unknown.

Arm Intervention/treatment
Experimental: Experimental
Full decision aid, consisting of education on osteoarthritis and treatment options, preferences and values elicitation, and personalized risk/benefit estimates based on patient's response to patient-reported outcome measures.
Other: OM1 Dell Shared Decision Making Tool
Decision aid meant to improve shared decision making among patients and providers.

Active Comparator: Control
Education component of the decision aid only.
Other: Education material from OM1 Dell Shared Decision Making Tool
Investigator-written educational material and quiz to test knowledge of osteoarthritis and treatment options.

Primary Outcome Measures :
  1. Knee Osteoarthritis Decision Quality Instrument [ Time Frame: Day 1 ]
    Decision process subscore. Participants receive 1 point for a response of "yes" or "a lot/some." The total points are summed and then divided by the total number of items to result in scores from 0-100%, with higher scores indicated a more shared decision making process.

  2. Knee Osteoarthritis Decision Quality Instrument [ Time Frame: Day 1 ]
    Concordance subscore (A summary score (0-100%) indicating the percentage of patients who received treatment that matched their stated preference will be generated.)

Secondary Outcome Measures :
  1. CollaboRATE [ Time Frame: Day 1 ]
    Level of shared decision making. Range of 0-9. Higher scores represent more shared decision making.

  2. Numeric rating scale-satisfaction [ Time Frame: Day 1 ]
    Patient satisfaction with management of condition. Range of 0-10 with 0 representing complete dissatisfaction and 10 representing complete satisfaction.

  3. Knee injury and osteoarthritis outcome score, joint replacement (KOOS JR) [ Time Frame: 6 months after baseline visit ]
    Measure of patient-reported, knee-related stiffness, pain, and function. Raw score range 0-28, converted to interval score of 0-100, where 0 represents total knee disability and 100 represents perfect knee health.

  4. Undergoing joint replacement surgery or not [ Time Frame: Day 1 ]
    Decision to undergo total knee replacement surgery (yes/no). Obtained by asking provider or through medical record note.

  5. Average time of patient visit and average time spent with provider [ Time Frame: Day 1 ]
    Minutes. Time of entire visit will be recorded in addition to time spent with primary provider.
