The Aim of This Study is to Assess the Feasibility of the Study Protocol and the Acceptability of the Mobile Application-Based Intervention. The Results Will Guide the Design and Evaluation of a Definitive, Larger-scale Study to Further Examine the Efficacy of the Refined Intervention.

About the research

This study is a pilot study for a larger future research project aimed at examining the effects of patient education delivered via a mobile application on patients' self-reported receipt of information in relation to their information needs, as well as on patient-reported quality of life, pain, and functional capacity, compared with traditional patient education provided during in-person appointments or by telephone. The primary objective of this pilot study is to assess the feasibility of conducting the forthcoming larger-scale study.

Research questions:

1. How does patient education delivered via a mobile application meet the information needs of patients undergoing joint replacement surgery, and is the intervention feasible to implement in a larger research setting?
2. How do the instruments used in the pilot study (EKhp/RKhp, EQ-5D-5L, NRS, and OKS/OHS) and the study design function when delivered via a mobile application for the intervention group and in conjunction with traditional patient education for the control group, and are the instruments and study design suitable for conducting a larger-scale study.

The study will be conducted as a randomized controlled trial (RCT). Patients will be allocated into two groups:

Intervention group: receives patient education via a mobile application. Control group: receives traditional patient education during face-to-face clinic visits or by telephone.

Data will be collected using questionnaires before surgery (three measurement points) and after surgery (two measurement points).

Who may be able to participate?

The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.

Inclusion Criteria:

• Primary knee or hip joint replacement surgery
• No previous visits to Coxa
• Age 18-75 years
• Proficiency in the Finnish language
• Body mass index (BMI) below 40
• Moderate alcohol consumption (AUDIT \< 20)
• Ability to use a mobile application (access to a compatible smartphone)
• The patient may have a mild systemic disease that does not significantly limit functional capacity (ASA I-II)
• The patient may also have a somewhat more severe condition, provided that underlying diseases are well controlled (ASA III)
• Medication use is moderate, consisting of 1-5 medications in addition to pain medication
• No use of anticoagulant medication
• No previously identified anesthetic complications

Exclusion Criteria:

• Previous joint surgery
• Functional impairment / disability
• Insufficient proficiency in the Finnish language
• No possibility to use a mobile application (no mobile phone)
• Patient with multiple comorbidities (multimorbid patient)
• The patient does not proceed to the surgical waiting list

Treatment, groups and participation

The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.
