The false promises of shared decision making in rehabilitation

In the recent years, Shared Decision Making (SDM) has been increasingly advocated as an ideal model of treatment decision-making during the medical encounter, as it has been shown to increase benefits for both clinicians and the health-care system (1).  But does SDM result in better outcomes for patients with painful musculoskeletal conditions?  In this article, we’ll address the “5 W’s” of SDM.

WHAT is Shared Decision Making (SDM)?

Although many definitions of SDM exist, all converge to a similar notion: SDM is a dynamic process by which the healthcare professional (not limited to the physician) and the patient influence each other in making health related choices or decisions (2). In 2015, a comprehensive review SDM for  multiple health-related pathologies suggested that outcomes associated with the cognitive-affective domain exhibit stronger effects, whereas non-cognitive health related outcomes (e.g., function) yield the smallest effects (3).

WHO integrated SDM in our healthcare systems?          

The concept of SDM has been advocated for more than 40 years and is highly supported within infrastructures of health-care systems.  The Agency of Healthcare Research and Quality advocates for a shared approach to care and a five-step process, which involves exploring and comparing the benefits, harms, and risks of each option, through meaningful dialogue about what matters most to the patient. Other initiatives have also embraced this approach, such as the Patient-Centered Outcomes Research Institute (PCORI), as well as decision-makers, through the Affordable Care Act, which urges the implementation of SDM in health care systems (1).

WHEN should we use SDM in the context of musculoskeletal rehabilitation?

It is well recognized that painful musculoskeletal conditions, are one of the leading reasons for lower quality of life and represent a major burden (4). Although SDM is often embedded in today’s health care reality, the true effects of SDM (ie: added-value over “standard” client-centered care practice) on patient reported outcomes in the context of musculoskeletal rehabilitation are less known.  To shed light on SDM’s influence on health related outcomes in patients presenting with musculoskeletal conditions, I was part of a systematic review of studies comparing SDM with a control intervention (with SDM as the manipulated variable), and which included one or more of the following outcome measures: well-being, costs, health related pain or disability measures, or quality of life.  Not a single study investigated the true effect (effectiveness) of SDM on patient reported outcomes in a musculoskeletal pain population, despite the reality that SDM has been advocated for many years. We only found one study which explored the effect of a decision aid (educational brochure that could be part of a decision process) on patient satisfaction and physical outcomes in a sample of patients with non-specific low back pain.  Although these authors found comparable satisfaction levels, they reported worse outcomes (pain/physical aspects) and lower cost-effectiveness for the intervention arm (5)!

The top 3 reasons WHY to remain skeptical to SDM’s integration in musculoskeletal rehabilitation

  1. Decision aids are underdeveloped in rehabilitation: One tactic to implement an ideal application of the SDM approach is by the use of decision aids (educational material), which will stimulate the exchange of information between both parties, and will then drive SDM.  However, in musculoskeletal rehabilitation, decision-aids are i) scarce, ii) described to be in their developmental phase and iii) seen as premature to implement in clinical practice (7). Furthermore, in the short term, they are likely to remain scarce since we don’t fully understand our own intervention effects.
  2. SDM’s fundamentals relate to potentially harmful treatment options: SDM is recommended in the context of management of persistent pain related to the musculoskeletal diseases (6).  However, this recommendation made by the American Pain Society mostly concerned the decision making process between invasive therapies (surgery) and interdisciplinary rehabilitation, two approaches with radically different levels of potential harm and risk.  It is when confronted by such decisions that the SDM process might better serve the patient and the health care system.  However, rehabilitation involves a very low probability of harm, such as increase mortality risk, compared to surgical or pharmacological options.
  3. Conundrum of pain science: A tenant of SDM involves the assumption that delivering the patient preference will lead to improved outcomes.  However, patients and health care professionals are not always on the same page – if patient and therapist do not share a common understanding of pain, the SDM process should be questioned. For example, with chronic pain, patients with maladaptive thoughts or detrimental behaviors may demand care that is detrimental to their own progression. In pain management, evidence supports adoption exercises and active approaches.  However, these options are often at the opposite end of the desirability spectrum by the patient.  In such circumstances, SDM could have a negative influence on outcomes as both patient/therapist can be off the track, and select/offer a non-optimal treatment.

WHERE to go from this point?

There are recognized potential benefits of SDM in a patient-centered care approach, as it explicitly gives a voice to individuals and offers them more control towards the healthcare they choose to receive. However, one can argue that further investigation of this concept is necessary before wholesale implementation and assumption of superiority, especially in chronic pain management, where there are often more questions than answers.  One could also recommend more emphasis on gaining an accurate perspective and common understanding as a meaningful way to enhance outcomes.  In this particular context, maybe “soft skills” like therapeutic alliance (8) and better communication/education strategies (9) might represent interesting options in the meantime.

Pr Tousignant-Laflamme is a registered physical therapist and researcher interested in developing and evaluating new ways to improve pain management in rehabilitation. His research program focuses on the treatment of chronic pain conditions, such as chronic back pain and complex regional pain syndrome (CRPS) as well as the development of pain assessment tools. His current research program focuses on three key areas of pain management: 1) Self-management programs; 2) Appraisal of therapeutic approach; 3) Development and validation of assessment tools. Finally, he has numerous research collaborations aimed to develop and validate various tools for measuring pain in vulnerable populations (ie: elderly, critical care).
