Presence and grade of undertreatment of pain in children with cerebral palsy

Abstract

Objectives: To investigate if chronic pain in children with cerebral palsy is undertreated with the current pharmacological/non-pharmacological interventions using a pain management index.

Methods: Parents of 120 children with cerebral palsy between the ages of 2-19 years from our region in Denmark answered a questionnaire about whether their child had everyday pain. When answering in pain, we inquired about pain status and pharmacological/non-pharmacological pain coping interventions. Everyday pain was viewed as chronic pain with acute exacerbations. Pain experienced was divided into worst pain (highest moments of pain intensity) and least pain (lowest moments of pain intensity). To describe and evaluate the effectiveness of pain interventions used, a pain management index was utilized. Everyday pain was assessed using a logistical regression by adjusting for age, sex, and gross motor function classification system level.

Results: 59/115 (0.51) of parents answering the questionnaire reported everyday pain. Of those, the median age was 10 years. For pain alleviation, massage was reported by parents as being used by 29/59 (0.49) children and paracetamol by 21/59 (0.36). Pain affected daily life in 44/59 (0.75). By our evaluation 44/59 (0.75) were inadequately treated for their pain. Our evaluation also revealed that 19/59 (0.32) of children in pain had inadequately treated pain combined with an undesirable intensity of least pain.

Conclusions: Half of the children with cerebral palsy experienced chronic pain according to our pain questionnaire answered by parents. Among these children three-quarters were insufficiently treated for their pain. In the same group, one-third were impacted by pain felt at both its highest and lowest moments of intensity. Massage therapy and paracetamol were the most frequently utilized pain-alleviating interventions. In our cohort, pain was undertreated and likely underdiagnose (Protocol number H-17008823).
