Effectiveness of communication strategies in the management of chronic postsurgical pain: a systematic review and meta-analysis
This systematic review and meta-analysis of 68 studies suggests that nurse-led interventions and combined cognitive behavioral therapy with education may reduce chronic postsurgical pain, although the overall evidence remains uncertain due to methodological limitations, heterogeneity, and a lack of impact from education alone or other communication strategies.

Imagine a patient leaving the hospital after a successful operation. The surgery is over, the wound is healing, and the immediate danger has passed. Yet, for a significant number of people, the pain does not fade away with the recovery. Instead, it lingers, transforming from a temporary signal of injury into a chronic condition that persists for months or even years. This is known as chronic postsurgical pain, a phenomenon where the body's natural alarm system fails to switch off after the tissue has repaired itself. It is a complex experience, influenced not just by the physical cut or the bone that was set, but by a person's mind, their fears, their expectations, and how they are spoken to by their medical team. Because pain is so deeply personal and variable, doctors have long sought better ways to communicate with patients before and after surgery, hoping that the right words and the right support could prevent this lingering suffering from taking hold.
A new comprehensive review of scientific research has taken a close look at whether these communication strategies actually work. The researchers gathered and analyzed data from 68 different studies involving thousands of patients who had undergone various surgeries, ranging from joint replacements and heart bypasses to cancer removals and spinal procedures. They focused specifically on interventions where the medical team used communication—such as education, counseling, psychological support, or remote check-ins—to see if these methods could reduce the amount of pain patients felt three months or more after their operations. The goal was to separate the methods that truly help from those that simply fill time, looking for a clear path to preventing long-term suffering.
The review found that not all forms of communication are created equal. When doctors or nurses simply handed out information sheets or gave standard verbal instructions without any deeper engagement, the results were generally the same as receiving no special communication at all. The studies showed that education alone, video demonstrations, or even using photographs to explain procedures did not significantly lower the rates of chronic pain or improve physical function compared to standard care. Similarly, using telehealth tools like phone calls or apps to check in on patients did not, on its own, produce a measurable difference in pain levels. The researchers also found no evidence that a mix of different communication methods, or pre-surgery physical preparation programs, reliably reduced the prevalence of chronic pain when looked at in isolation.
However, the picture changed when the communication became more active and personalized. The review highlighted two specific approaches that showed promise in reducing pain and improving how well patients could move and function in the months following surgery. The first was nurse-led interventions, where a nurse took a central role in guiding the patient through their recovery with consistent, supportive contact. The second was a combination of cognitive behavioral therapy—helping patients change the way they think about and react to pain—paired with educational support. In the studies that used these combined methods, patients reported noticeably less pain and better physical outcomes than those who received standard care. One study even found that a specific type of therapy using mirrors to trick the brain into seeing a healed limb helped reduce pain after breast surgery, suggesting that visual and psychological tools can have a tangible effect on physical sensation.
Despite these encouraging signs, the researchers caution that the evidence is not yet strong enough to declare these methods a guaranteed solution. The studies they analyzed varied widely in how they were conducted, the types of patients involved, and the specific surgeries performed. Many of the studies had small groups of participants, and some had flaws in their design that made it difficult to be certain about the results. Because of these limitations, the certainty of the findings is considered low. The data suggests that nurse-led care and the combination of psychological therapy with education are worth exploring further, but the current evidence does not yet prove they will work for everyone. The review concludes that while we have identified some promising elements in how we talk to and support surgical patients, the medical community needs more rigorous, high-quality research to determine exactly how to use these tools to stop chronic pain before it starts.
