Childhood chronic pain
Childhood chronic pain affects at least 5% of the population under the age of 18, according to conservative epidemiological studies. Rates of paediatric chronic pain have also increased in the past 20 years.[1] While chronic pain conditions vary significantly in severity, they often affect children's mental health, academic performance, and general quality of life.[2]
Classification and epidemiology
Chronic pain is defined as pain that lasts at least 3–6 months and, in the case of injury or surgery, remains present after standard recovery time has elapsed.[3] The ICD-11 provides seven categories for diagnosing chronic pain:
- Chronic primary pain
- Chronic cancer pain
- Chronic postsurgical and posttraumatic pain
- Chronic neuropathic pain
- Chronic headache and orofacial pain
- Chronic visceral pain
- Chronic musculoskeletal pain[3]
Childhood chronic pain can be caused by a number of conditions, including the following:[4]
Condition | Symptoms | Known causes and risk factors | Estimated prevalence | Treatments |
---|---|---|---|---|
Chronic abdominal pain | Recurrent abdominal pain, usually without a known organic cause[5] | Usually unknown[5] | 8.4%[6] | Drug therapies, cognitive behavioural therapy (CBT) [5] |
Chronic headache | Recurrent headache (at least 15 days per month, 4 hours per day)[7] | Sex (more common in females), psychological disturbances, obesity, overuse of caffeine or headache medication, other chronic pain conditions[7] | 1.5% - 3.4% | Antidepressants, beta blockers, anticonvulsants, NSAIDs, botulinum toxin, CBT[7] |
Complex regional pain syndrome | Severe burning/throbbing pain (usually in a limb), swelling, sensitivity, changes in skin colour and texture[8] | Injury or trauma[8] | Unknown[9] | Pain relievers, corticosteroids, bone-loss medication, sympathetic nerve-blocking medication, intravenous ketamine, physical therapy, biofeedback, spinal cord stimulation[8] |
Juvenile fibromyalgia | Widespread muskuloskeletal pain, headache, sleep disturbances, fatigue[10] | Genetics, sex (more common in females), infections, trauma, rheumatic disease[10] | 1.2% - 6.2%[11] | Antidepressants, anticonvulsants, pain relievers, CBT[10] |
Juvenile rheumatoid arthritis | Joint pain, swelling, and stiffness[12] | Genetics, sex (more common in females)[12] | 0.4%[13] | NSAIDs, TNF blockers, immune suppressants, corticosteroids, physical therapy[12] |
Management
Chronic pain can be treated in a number of ways, and varies depending on the type and severity of the condition. Common pain medications prescribed to children include paracetamol, ibuprofen, and acetylsalicylic acid.[14] Researchers have also found that psychotherapies are often helpful in reducing functional disability in children with chronic pain. A meta-analysis by Christopher Eccleston and colleagues found that cognitive behavioural therapy (CBT) significantly reduced pain severity for children with chronic headaches.[15] Additionally, biofeedback and relaxation therapy can be used in conjunction with CBT to treat chronic pain. Research thus far has typically found small effects for improving psychological wellbeing, but more robust outcomes for pain relief.[16] Studies have also found significant pain relief effect for alternative medicine treatments, such as acupuncture[17] and herbal medicine[18]. Further research is needed to evaluate the efficacy of other alternative medicine techniques, such as arts therapy, homeopathy, and hypnosis.[18]
Outcomes
Chronic pain often interferes with children's ability to attend and succeed in school. Children with severe disorders are particularly likely to miss school because of debilitating pain, as well as for medical appointments. High rates of school absence are associated with poor adjustment and psychosocial wellbeing among children with chronic illnesses.[19]
In a study of patients at a paediatric pain clinic, researchers found that chronic pain had a significant negative impact on quality of life. Depression was also prevalent, and was correlated with functional disability.[20] Additionally, psychosocial adjustment is a better predictor of school attendance than pain severity, which suggests that it is an important variable in examining outcomes of children with chronic pain.[21] Paediatric chronic pain often impacts quality of life for the families of children affected, with mothers having particularly low health-related quality of life on average.[22] Parents of children with chronic pain conditions allocate considerable physical, financial, and emotional resources towards health care for their child. For example, a study by Ho and colleagues found that primary caregivers for chronically ill children spent an average of around $8800 and 28.5 hours on medical appointments in the past three months, causing them to miss an average of 4 days of work.[23]
Factors affecting outcomes
Demographic factors
Chronic pain, especially chronic headache, is more common in girls, older children, and children from low socioeconomic status backgrounds.[1] According to researchers Anna Huguet and Jordi Miró, the most common locations for paediatric chronic pain are the head and abdomen. These two locations are more likely to be sources of chronic pain for girls, whereas boys are more likely to experience lower limb pain. Girls are also more likely than boys to experience multiple sources of pain.[14] The prevalence of chronic pain among girls increases sharply between the ages of 12 and 14, which leads some researchers to believe that it is linked to menarche and other hormonal changes during adolescence.[24]
Age also has a significant impact on children's experiences with chronic pain. Young children often cannot describe their pain in ways that adults understand, and even older children may lack the vocabulary to clearly communicate with medical professionals.[25]
Family support
For chronic pain patients, family support is an important factor in promoting successful pain management and rehabilitation.[26] While healthy family interaction has a positive impact on paediatric pain patients, overprotectiveness and unhealthy relationship demands can foster depressive symptoms.[27]
School support
School support is also an important factor influencing paediatric chronic pain outcomes. When children receive appropriate support from teachers and school counsellors, they are more likely to achieve attain success and psychological wellbeing.[19] This process can often be facilitated by a paediatric nurse practitioner (PNP), who coordinates a child's education with his or her medical treatment.[28]
