Stratified Physiotherapeutic (Blended) Care in Neck and Shoulder Complaints

A Stratified Approach Integrated With eHealth in Primary Care Physiotherapy for Patients With Neck and/or Shoulder Complaints

The aim of this cluster RCT is to investigate the clinical effectiveness of a Stratified Blended Approach for patients with neck and/or shoulder complaints on pain and disability over 9 months, compared to usual physiotherapy care. Our secondary aims are twofold: to investigate the effectiveness of the Stratified Blended Approach for patients with neck and/or shoulder complaints on pain intensity, health-related quality of life, illness perceptions, self-management skills, physical activity, exercise adherence, self-perceived effect and satisfaction at 3 and 9 months, compared to usual physiotherapy care; to investigate the cost-effectiveness and cost-utility of the Stratified Blended Approach for patients with neck and/or shoulder complaints, compared to usual physiotherapy care. In the Stratified Blended Approach arm, physiotherapists will match I) the content and intensity of physiotherapy care to the patient's risk of persistent disabling pain, categorized as low, medium or high (using the Keele STarT MSK Tool) and II) the mode of care delivery to the patient's suitability and willingness to receive blended care. The control arm will receive physiotherapy as usual. This study is financially supported by the Scientific College Physiotherapy (WCF), part of the Royal Dutch Association for Physiotherapy (KNGF). WCF has no role in study design, data collection and analysis, decision to publish, or preparation of the manuscripts. External peer-review took place during the funding process. The results will be publicly disclosed unreservedly.

Intervention: According to the Stratified Blended approach, patients will be matched to an appropriate treatment based on their risk of persistent disabling pain (assessed with the Keele STarT MSK Tool - either low, medium or high risk) and their suitability for blended care (assessed with the Dutch Blended Physiotherapy Checklist - either suitable or unsuitable for blended care). Based on patients risk profile, the physiotherapy treatment will be targeted to patients' individual needs. If considered suitable for blended care, the patient will receive a digital and face-to-face blend of physiotherapy treatment (e-Exercise) in which an app with personalized information, exercises and physical activity modules is integrated with face-to-face physiotherapy care. If patients are considered unsuitable for blended care, they will receive an information workbook with similar content as the app will be integrated with face-to-face physiotherapy. The app and the information workbook aims to support adherence to physical activity and exercise recommendations. Content of care was based on the Dutch KNGF Clinical Practice Guidelines for Physiotherapy Neck pain, Complaints of Arm, Neck and Shoulder (CANS) and Subacromial complaints. Control group: Usual physiotherapy. Content of care was based on the Dutch KNGF Clinical Practice Guidelines for Physiotherapy Neck pain, Complaints of Arm, Neck and Shoulder (CANS) and Subacromial complaints.

A multicenter, pragmatic, two-arm, parallel-group, cluster randomized controlled trial (cRCT) will be conducted.

Due to the nature of the intervention, blinding of participating physiotherapists is not possible. However, neither physiotherapists nor patients in the usual physiotherapy care arm will be informed about the Stratified Blended Approach arm. During the analyses, the researchers will be blinded to group allocation until the entire analysis will be completed.

First, physiotherapists will use two stratification tools to decide the most suitable content and intensity as well as mode of care delivery of primary care physiotherapy. The content and intensity of physiotherapy will be matched to the patient's risk of persistent disabling pain as assessed with the Keele STarT MSK tool. The mode of care delivery of physiotherapy will be matched to the patient's suitability for blended care as assessed using the Dutch Blended Physiotherapy Checklist (i.e. yes or no). Second, physiotherapists will receive two practical tools to provide the matched treatment of the mode of care delivery. If considered suitable for blended care, the patient will receive a blended physiotherapy treatment (e-Exercise), in which a smartphone app with personalized information, exercises and physical activity modules is an integral part of physiotherapy treatment. If patients are considered not to be suitable for blended care, a paper-based workbook will be integrated.

Patients in the usual physiotherapy arm will be offered usual care (face-to-face or video consults) based upon the recommendations of the guidelines of the Royal Dutch Association for Physiotherapy (KNGF). The clinical guideline for neck pain, recommends categorization in treatment profiles based on: the severity of neck pain, the course of symptoms (normal vs. deviant) and the presence of psychosocial factors that may hinder recovery (yes vs. no). The clinical guideline for complaints of the arm, neck and shoulder recommends categorization in treatment profiles based on the region of complaints indicated as most problematic and the relationship between complaints, disabilities, and limitations in participation. No stratification tools to identify patient subgroups and subsequently match them to a treatment are recommended by the guidelines.

The primary outcome is the combined region-specific pain and disability score over 9 months follow-up, assessed by the Neck Pain and Disability Scale (NPAD) for patients with primarily neck complaints and by the Shoulder Pain and Disability Index (SPADI) for patients with primarily shoulder complaints. A higher total score (0-100 for both outcome measures) indicates increased pain and functional limitations.

Health-related quality of life will be measured with the 36-Item Short Form Health Survey (SF-36). The questionnaire consists of eight subscales (physical functioning, role limitations due to physical health, role limitations due to emotional problems, energy/fatigue, emotional well-being, social functioning, pain (over the last 4 weeks) and general health). Scores for each subscale will be calculated (0-100). Higher scores indicate a better health-related quality of life.

Patients' self-management skills are assessed with the Dutch version of the short form Patient Activation Measure (PAM13-Dutch). The PAM 13-Dutch is a reliable 13-item instrument and assesses patient (or consumer) self-reported knowledge, skills and confidence for self-management of one's health or chronic condition. The answering categories per item are 4-point Likert scales, ranging from totally disagree to totally agree and 'non applicable'. A higher score (range 1-100) indicates a higher level of self-management.

Physical activity will be objectively measured with an Actigraph accelerometer. The Actigraph accelerometer is a reliable tool for measuring physical activity in adults. Participants will be instructed to wear the accelerometer on their waist for five consecutive days, except when sleeping, showering, bathing or swimming. Average amount of moderate or vigorous physical activity (MVPA) per day will be calculated.

Satisfaction with treatment outcome will be measured with an 8-point Likert scale question: 'All things considered, how satisfied are you with the results of the treatment for your neck and/or shoulder complaints? (1 = extremely satisfied, 7 = extremely dissatisfied, 8 = not sure/no opinion)

This outcome will be combined to a region-specific pain and disability score over 3 months follow-up, assessed by the Neck Pain and Disability Scale (NPAD) for patients with primarily neck complaints and by the Shoulder Pain and Disability Index (SPADI) for patients with primarily shoulder complaints. A higher total score (0-100 for both outcome measures) indicates increased pain and functional limitations.

A cost-utility analysis (CUA) will be performed for QALYs and a cost-effectiveness analysis (CEA) for the combined region-specific pain and disability score, both of which will be performed from the societal and the healthcare perspective. From the societal perspective all costs will be taken into account, irrespective of who pays or benefits, whereas solely those borne by the healthcare sector will be included if the healthcare perspective is applied.

The content and intensity of physiotherapy care will be measured by a case report form, filled out by the physiotherapist at the end of the treatment period or after 3 months. Information of the risk of persistent disabling pain, the suitability for blended care, the physiotherapists diagnosis of the presenting problem, the number of physiotherapy sessions, deviations from the study protocol, and content of the physiotherapy sessions will be collected.
