Caregivers' Beliefs Regarding Pain in Children With Cognitive Impairment: Relation Between Pain Sensation and Reaction Increases With Severity of Impairment

A Case of Secondary Pulmonary Hypertension in a Patient With Atrial Septal Defect and Fetal Alcohol Syndrome

We report a case of a 34-year-old man with fetal alcohol syndrome (FAS) presenting with dyspnea, cough, and hoarse voice. The patient was found to have severe pulmonary hypertension secondary to a large atrial septal defect (ASD). In this article, we discuss the challenges patients with FAS and other patients with cognitive impairments face that could explain the first diagnosis of such a large cardiac birth defect being made in the patient's adulthood. Moreover, severe pulmonary hypertension due to ASD also presents a therapeutic dilemma, as shunt closure can lead to a worsening of the condition.

The recognition, assessment and perceptions of total pain in people with profound intellectual disabilities: A mixed methods systematic review

BACKGROUND

People with profound intellectual disabilities are a population with complex comorbidities. Total pain recognises the interconnectedness of aspects of pain; social, psychological, physical, emotional, spiritual. Pain is under-recognised due to communication challenges and carers perceptions. This review's purpose is to synthesise current literature and provide guidance for future research and care.

METHODS

Five databases were searched in this mixed methods systematic review (Cinahl, Medline, Psycinfo, Web of Science, Scopus). Articles retrieved were reported via a PRISMA flow diagram. Quality appraisal utilised the mixed methods appraisal tool (MMAT). A convergent qualitative design was the method of data synthesis.

RESULTS

Data from 16 included articles generated four themes; Absent voices, reductionist assessment, pain intensity, valuing expertise. Data included physical pain only.

CONCLUSION

Multifaceted pain needs inclusion in research. Assessment must consider the unique expressions of pain by individuals with profound intellectual disabilities. A sharing of expertise may improve pain care.

Pain Management in the Most Vulnerable Intellectual Disability: A Review

This review is made up of two parts; the first part discussing intellectual disability (ID) in general, while the second part covers the pain associated with intellectual disability and the challenges and practical tips for the management of pain associated with (ID). Intellectual disability is characterized by deficits in general mental abilities, such as reasoning, problem solving, planning, abstract thinking, judgment, academic learning, and learning from experience. ID is a disorder with no definite cause but has multiple risk factors, including genetic, medical, and acquired. Vulnerable populations such as individuals with intellectual disability may experience more pain than the general population due to additional comorbidities and secondary conditions, or at least the same frequency of pain as in the general population. Pain in patients with ID remains largely unrecognized and untreated due to barriers to verbal and non-verbal communication. It is important to identify patients at risk to promptly prevent or minimize those risk factors. As pain is multifactorial, thus, a multimodal approach using both pharmacotherapy and non-pharmacological management is often the most beneficial. Parents and caregivers should be oriented to this disorder, given adequate training and education, and be actively involved with the treatment program. Significant work to create new pain assessment tools to improve pain practices for individuals with ID has taken place, including neuroimaging and electrophysiological studies. Recent advances in technology-based interventions such as virtual reality and artificial intelligence are rapidly growing to help give patients with ID promising results to develop pain coping skills with effective reduction of pain and anxiety. Therefore, this narrative review highlights the different aspects regarding the current status of the pain associated with intellectual disability, with more emphasis on the recent pieces of evidence for the assessment and management of pain among populations with intellectual disability.

Participation, challenges and needs in children with down syndrome during cancer treatment at hospital: a qualitative study of parents' experiences

Background

Studies report that it can be challenging to assess and treat side-effects and symptoms among children who have impairments and difficulties in expressing their needs. Children with Down syndrome have an increased vulnerability and an increased risk for contracting leukaemia. There is sparse knowledge about the parental experience of how treatment and side-effects affect children with Down syndrome with leukaemia, as well as the role of participation during treatment.

Purpose

This study aimed to explore the perceptions of parents of children with Down syndrome and leukaemia regarding their child's treatment, side effects and participation during hospital care.

Methods

A qualitative study design was used, and interviews were conducted with a semi-structured interview-guide. Fourteen parents of 10 children with Down syndrome and acute lymphoblastic leukaemia from Sweden and Denmark, 1-18 years of age, participated. All children had completed therapy or had a few months left before the end of treatment. Data was analysed according to qualitative content analysis.

Results

Four sub-themes were identified: (1) Continuously dealing with the child's potential susceptibility; (2) Confidence and worries regarding decisions related to treatment regulation; (3) Challenges in communication, interpretation, and participation; and (4) Facilitating participation by adapting to the child's behavioural and cognitive needs. The sub-themes were bound together in an overarching theme, which expressed the core perception "Being the child's spokesperson to facilitate the child's participation during treatment". The parents expressed this role as self-evident to facilitate communication regarding the needs of the child, but also regarding how the cytotoxic treatment affected the vulnerable child. Parents conveyed the struggle to ensure the child's right to receive optimal treatment.

Conclusion

The study results highlight parental challenges regarding childhood disabilities and severe health conditions, as well as communication and ethical aspects regarding to act in the best interests of the child. Parents played a vital role in interpreting their child with Down syndrome. Involving parents during treatment enables a more accurate interpretation of symptoms and eases communication and participation. Still, the results raise questions regarding issues related to building trust in healthcare professionals in a context where medical, psychosocial and ethical dilemmas are present.

[Challenges in pain assessment and management among individuals with intellectual and developmental disabilities : German version]

INTRODUCTION

Intellectual and developmental disabilities (IDD) include conditions associated with physical, learning, language, behavioural, and/or intellectual impairment. Pain is a common and debilitating secondary condition compromising functional abilities and quality of life.

OBJECTIVES

This article addresses scientific and clinical challenges in pain assessment and management in individuals with severe IDD.

METHODS

This Clinical Update aligns with the 2019 IASP Global Year Against Pain in the Vulnerable and selectively reviews recurring issues as well as the best available evidence and practice.

RESULTS

The past decade of pain research has involved the development of standardized assessment tools appropriate for individuals with severe IDD; however, there is little empirical evidence that pain is being better assessed or managed clinically. There is limited evidence available to inform effective pain management practices; therefore, treatment approaches are largely empiric and highly variable. This is problematic because individuals with IDD are at risk of developing drug-related side effects, and treatment approaches effective for other populations may exacerbate pain in IDD populations. Scientifically, we are especially challenged by biases in self-reported and proxy-reported pain scores, identifying valid outcome measures for treatment trials, being able to adequately power studies due to small sample sizes, and our inability to easily explore the underlying pain mechanisms due to compromised ability to self-report.

CONCLUSION

Despite the critical challenges, new developments in research and knowledge translation activities in pain and IDD continue to emerge, and there are ongoing international collaborations.

Challenges in pain assessment and management among individuals with intellectual and developmental disabilities

Pain is common for individuals with intellectual and developmental disabilities, and we need to accelerate the use of evidence-based approaches to assess and manage pain.

Assessing pain in children in the perioperative setting

Pain assessment and management in children is challenging for a number of reasons. This paper aims to identify these challenges and highlight strategies for effective pain assessment and management in children in the perioperative setting.

[Pain in children with neurological impairment: A review from the French Pediatric Neurology Society]

Management of pain is one of the major expectations of children with neurological impairment and their families. The medical literature is poor on this topic accounting for approximately 0.15 % of the publications on pain in general. The objective of the French Pediatric Neurology Society was to review the current knowledge on this topic. Bibliographic research was conducted with PubMed and RefDoc for publications between 1994 and 2014 in French or English. A total of 925 articles were retrieved and 92 were selected for review. Pain is common in this population: a 2-week survey indicated that pain occurs in 50-75 % of children. Pain negatively impacts the quality of life of children and their parents. Children with neurological impairment express their pain with pain expression patterns and specific patterns common to children (change of tone, abnormal movements, spasticity, paradoxical reactions, such as laughter, self-injury or vasomotor dysfunction). Some children with neurological impairment are able to use self-report pain scales. If not, observational measures should be used. Behavioral rating scales specifically designed for this population are more sensitive than others. Scales must be selected according to children's communication skills, type of pain, and the context. Sometimes behavioral changes are the only expression of pain: any change in sleep, tone, feeding, or mood must suggest pain in this population. Management of pain remains difficult. There are no specific guidelines. Procedural pain management guidelines and the usual analgesic drugs can be used in children with neurological impairment with specific concerns regarding tolerance and side effects. These children are particularly at risk for neuropathic pain. A multidisciplinary approach is helpful, involving physicians, nurses, physiotherapists, psychologists and parents.

Caring for children with intellectual disabilities part 1: Experience with the population, pain-related beliefs, and care decisions

Some children with intellectual disabilities (ID): experience pain more frequently than children without ID, express their pain differently, and are incapable of providing self-reports. No research has examined disability and pain-related beliefs of respite workers (RW) and their relations to pain assessment and management decisions for children with ID.

OBJECTIVES

(1) compare disability and pain-related beliefs between RW and a sample with little experience in ID; (2) determine whether individuals' beliefs and personal characteristics are related to pain assessment and management decisions.

PARTICIPANTS

Fifty-six RW (aged: 18-67 years, M_age=33.37, 46 female) and 141 emerging adults (aged: 18-31 years, M_age=19.67, 137 female).

PROCEDURE/MEASURES

In an online survey, participants responded to six vignettes depicting pain in children with ID, and completed measures of pain and disability-related beliefs.

RESULTS/DISCUSSION

Compared to those without experience, RW held more positive disability-related beliefs, t(192)=4.23, p<0.001. Participants' pain-related beliefs (e.g., sensitivity to pain) differed depending on severity of the child's ID and participant group. Participants' pain-related beliefs predicted care decisions. Results provide initial insight into RW pain-related beliefs about children with ID, and a basic understanding of the relations among pain beliefs, personal characteristics and pain-related decisions.

Observer perceptions of pain in children with cognitive impairments: vignette development and validation

Aim: Develop vignettes depicting different pain types in verbal and nonverbal children with cognitive impairments that could help examine pain assessment and management decisions of secondary caregivers, and conduct initial convergent and divergent validity analyses. Methods: For six vignettes, 76 undergraduate students (38 females, mean age = 19.55) rated (0–10): pain intensity, difficulty rating pain intensity, need for medical attention and need for other attention (e.g., physical comfort). Results: Ratings significantly varied by pain source (e.g., headache was rated more painful than injections). Verbal ability did not impact ratings. Conclusion: Vignettes could serve as an alternative method to study pain decisions by caregivers of children with cognitive impairments when ethical barriers limit more naturalistic research.

A comparison of observers' and self-report pain ratings for children with cerebral palsy

OBJECTIVES

This study aimed to examine (1) the relationship between children's self-reports of pain and their different care providers' pain ratings, (2) the relationship between different care providers' ratings of pain in children with cerebral palsy (CP), and (3) whether the child's level of disability influences care providers' pain ratings.

METHODS

Sixty-three children with CP were separated into 2 groups according to whether they were able to pass a self-report training task. Pain was rated using a Numerical Rating Scale and the Non-Communicating Children's Pain Checklist-Postoperative Version (NCCPC-PV). Children were observed during their regular physiotherapy sessions at 3 separate time segments (Baseline, Stretch Procedure, and Recovery).

RESULTS

As anticipated, results showed that all observers reported significantly higher pain scores during a physiotherapy stretching procedure than the baseline and recovery segments. Observers' NCCPC-PV scores were significantly higher during the stretch procedure for the children who did not pass the self-report training task. Findings also indicated that parents tended to report significantly lower pain scores compared with both their children and other observers.

CONCLUSIONS

The findings bring into question the accuracy of single-observer pain ratings for children with CP and possess implications for the management of pain in children with CP.

Convergent validity evidence for the Pain and Discomfort Scale (PADS) for pain assessment among adults with intellectual disability

OBJECTIVES

The main aim of the study was to generate initial convergent validity evidence for the Pain and Discomfort Scale (PADS) for use with nonverbal adults with intellectual disabilities.

MATERIALS AND METHODS

Forty-four adults with intellectual disability (mean age=46, 52% male) were evaluated using a standardized sham-controlled and blinded sensory testing protocol, from which Facial Action Coding System (FACS) and PADS scores were tested for (1) sensitivity to an array of calibrated sensory stimuli; (2) specificity (active vs. sham trials); and (3) concordance.

RESULTS

The primary findings were those participants who were reliably coded using both FACS and PADS approaches as being reactive to the sensory stimuli (FACS: F(2,86)=4.71, P<0.05, PADS: F(2,86)=21.49, P<0.05) (sensitivity evidence), not reactive during the sham stimulus trials (FACS: F(1,43)=3.77, P=0.06, PADS: F(1,43)=5.87, P=0.02) (specificity evidence), and there were significant (r=0.41 to 0.51, P<0.01) correlations between PADS and FACS (convergent validity evidence).

DISCUSSION

FACS is an objective coding platform for facial expression. It requires intensive training and resources for scoring. As such it may be limited for clinical application. PADS was designed for clinical application. PADS scores were comparable with FACS scores under controlled evaluation conditions providing partial convergent validity evidence for its use.

Motor function predicts parent-reported musculoskeletal pain in children with cerebral palsy

BACKGROUND

The relationship between pain and motor function is not well understood, especially for children and adolescents with communication and motor impairments associated with cerebral palsy (CP).

OBJECTIVES

To determine whether a predictive relationship between motor function and musculoskeletal pain exists in children with CP.

METHODS

Following informed consent, caregivers of 34 pediatric patients with CP (mean [± SD] age 9.37±4.49 years; 80.0% male) completed pain- and function-related measures. Parents completed the Dalhousie Pain Interview and the Brief Pain Inventory based on a one-week recall to determine whether pain had been experienced in the past week, its general description, possible cause, duration, frequency, intensity and interference with daily function. The Gross Motor Function Classification System (GMFCS) was used to classify the motor involvement of the child based on their functional ability and their need for assistive devices for mobility.

RESULTS

GMFCS level significantly predicted parent-reported musculoskeletal pain frequency (P<0.02), duration (P=0.05) and intensity (P<0.01). Duration of pain was significantly related to interference with activities of daily living (P<0.05).

CONCLUSIONS

Children with CP with greater motor involvement, as indexed by GMFCS level, may be at risk for increased pain (intensity, frequency and duration) that interfers with activities of daily living. The clinical index of suspicion should be raised accordingly when evaluating children with developmental disability who cannot self-report reliably.

Dental pain in children with intellectual disabilities: caregivers' perspective

Purpose. Description of pain is generally difficult in children, and more so in those with intellectual disabilities (ID). Aim. This study is aimed at evaluating dental pain from caregivers' perspective in children with ID. Methods. The study sampled 86 children (33 with ID, 53 normally developing) ages ranges from birth to 16 years old among those visiting the School of Dentistry, King Abdulaziz University, Saudi Arabia. Caregivers were asked about their awareness of dental pain in their wards using the Dental Discomfort Questionnaire (DDQ+). The children were examined for dental caries and periodontal status. Results. The mean DDQ+ in children with ID (4.55 ± 3.46) was not significantly different from that in healthy children (4.19 ± 3.26, P = 0.7). Children with ID had more salivation (P = 0.01) and were putting their hands inside their mouths more often (P = 0.003). Conclusions. Caregivers can recognize dental pain-related behaviors in children with ID such as excessive salivation and putting hands inside the mouth more often.

Self-injurious behaviour in intellectual disability syndromes: evidence for aberrant pain signalling as a contributing factor

BACKGROUND

In most individuals, injury results in activation of peripheral nociceptors (pain-sensing neurons of the peripheral nervous system) and amplification of central nervous system (CNS) pain pathways that serve as a disincentive to continue harmful behaviour; however, this may not be the case in some developmental disorders that cause intellectual disability (ID). Moreover, individuals affected by ID disorders may initiate self-injurious behaviour to address irritating or painful sensations. In normal individuals, a negative feedback loop decreases sensation of pain, which involves descending inhibitory neurons in the CNS that attenuate spinal nociceptive processing. If spinal nociceptive signalling is impaired in these developmental disorders, an exaggerated painful stimulus may be required in order to engage descending anti-nociceptive signals.

METHODS

Using electronic databases, we conducted a review of publications regarding the incidence of chronic pain or altered pain sensation in ID patients or corresponding preclinical models.

RESULTS

There is a body of evidence indicating that individuals with fragile X mental retardation and/or Rett syndrome have altered pain sensation. These findings in humans are supported by mechanistic studies using genetically modified mice harbouring mutations consistent with the human disease. Thus, once self-injurious behaviour is initiated, the signal to stop may be missing. Several developmental disorders that cause ID are associated with increased incidence of gastroesophageal reflux disease (GERD), which can cause severe visceral pain. Individuals affected by these disorders who also have GERD may self-injure as a mechanism to engage descending inhibitory circuits to quell visceral pain. In keeping with this hypothesis, pharmacological treatment of GERD has been shown to be effective for reducing self-injurious behaviour in some patients. Hence, multiple lines of evidence suggest aberrant nociceptive processing in developmental disorders that cause ID.

CONCLUSIONS

There is evidence that pain pathways and pain amplification mechanisms are altered in several preclinical models of developmental disorders that cause ID. We present hypotheses regarding how impaired pain pathways or chronic pain might contribute to self-injurious behaviour. Studies evaluating the relationship between pain and self-injurious behaviour will provide better understanding of the mechanisms underlying self-injurious behaviour in the ID population and may lead to more effective treatments.

Parental assessment of pain coping in individuals with intellectual and developmental disabilities

Pain coping is thought to be the most significant behavioural contribution to the adjustment to pain. Little is known about how those with intellectual and developmental disabilities (IDD) cope with pain. We describe parental reported coping styles and how coping relates to individual factors. Seventy-seven caregivers of children and adults with IDD reported on coping styles using the Pediatric Pain Coping Inventory (PPCI), pain behaviour using the Non-Communicating Children's Pain Checklist-Revised (NCCPC-R), illness-related interactions using the Illness Behaviour Encouragement Scale (IBES) and past pain experience using the Structured Pain Questionnaire. Scores were compared across mental ages and interactions between pain coping and the other factors were explored. A Multivariate Analysis of Variance (MANOVA) by mental age group ('≤4 years', '5-11 years' and '≥12 years') revealed that those in the '5-11 years' mental age group used more coping styles than those in the '≤4 years' mental age group, and those in the '≥12 years' group used more cognitively demanding coping styles than the other two groups (F(10,130)=2.68, p=.005). Seeking Social Support (r=.39, p=.001) and Catastrophizing/Helplessness (r=.33, p<.01) coping styles were significantly related to a greater display of pain behaviour. Those with younger mental ages, who Seek Social Support or Catastrophize, also displayed more pain behaviour, which may be an attempt to seek external resources when pain is beyond their ability to deal with independently.

Pain assessment in people with profound intellectual and multiple disabilities; a pilot study into the use of the Pain Behaviour Checklist in everyday practice

Because of their physical and general health problems, people with a combination of profound intellectual and severe or profound motor disabilities (PIMD) are at risk of pain-related medical conditions. They are fully dependent on support professionals for the detection and accurate interpretation of nonverbal pain behaviour. These professionals can use a recently developed instrument, the Pain Behaviour Checklist (PBC), to assess pain in post-operative situations for children with PIMD. It is not yet known whether this instrument can also be used to identify pain in both children and adults in daily care situations. The aim of this pilot study was therefore threefold: to establish (1) whether the PBC can be used to identify pain in day-to-day situations in people with PIMD, (2) which behaviours are most frequently identified as indices of pain behaviour, and (3) whether there is a difference in pain-related behaviour between children and adults. In total, 32 people with PIMD participated in the study (16 children with a mean age of 10.4 years and 16 adults with a mean age of 46.7 years). Each participant was videotaped twice during a planned care moment in which we assumed that pain was prevalent. During each observation, pain was scored by the direct support professional using the Visual Analogue Scale (VAS) and by two trained independent observers using the PBC. The reliability (both intrarater and interrater) of the PBC was analysed by calculating Spearman's rho. Validity was analysed by correlating the PBC with the VAS scores; Phi was calculated for both children and adults. Finally, positive scores on each separate item of the PBC were analysed in adults and children in order to discover possible differences between pain behaviour in each group. The interrater reliability of the PBC is .63 (p<.05) and the intrarater reliability was .88 (p<.05). Phi, as a measure of the agreement on pain/no pain between the VAS and the PBC, is .75 (p<.05) in children and .28 (p<.05) in adults. Adults were more likely to exhibit the pain-related behaviours of 'tense face', 'deeper naso-labial furrow' and 'moaning and groaning', whereas children made more 'penetrating sounds of restlessness'. Based on this pilot study, we conclude that the PCB's reliability when used in daily practice with people with PIMD is satisfactory. However, although the validity is good for children, it appears insufficient for adults. It seems that children display different pain-related behaviours than adults. More research is needed into the proper assessment of pain in people with PIMD, especially adults, by health care professionals in daily practice. We also need a better understanding of the extent to which the knowledge and experience of care professionals play a role in detecting (chronic) pain behaviour in both children and adults and of how people with PIMD cope with pain.

Pain assessment for children: overcoming challenges and optimizing care

There is growing evidence that children have short- and long-term physical, physiological, and psychological effects due to untreated acute pain. Because the majority of children who seek care in an emergency department present with pain or experience pain during the evaluation and treatment in the emergency department, optimal assessment and treatment of pain are paramount for this population. This review will highlight the many complexities of the assessment of pain for the pediatric patient. In addition, a variety of factors that affect the self-report of pain in children will be identified. Optimizing the utility of a pain assessment remains a challenge for the health care provider in the emergency setting. The common goal of a decreased experience of pain for children through improved analgesic administration remains.

The opinion of clinical staff regarding painfulness of procedures in pediatric hematology-oncology: an Italian survey

Background

Beliefs of caregivers about patient's pain have been shown to influence assessment and treatment of children's pain, now considered an essential part of cancer treatment. Painful procedures in hematology-oncology are frequently referred by children as the most painful experiences during illness. Aim of this study was to evaluate professionals' beliefs about painfulness of invasive procedures repeatedly performed in Pediatric Hemato-Oncology Units.

Methods

Physicians, nurses, psychologists and directors working in Hemato-Oncology Units of the Italian Association of Pediatric Hematology-Oncology (AIEOP) were involved in a wide-nation survey. The survey was based on an anonymous questionnaire investigating beliefs of operators about painfulness of invasive procedures (lumbar puncture, bone marrow aspirate and bone marrow biopsy) and level of pain management.

Results

Twenty-four directors, 120 physicians, 248 nurses and 22 psychologists responded to the questionnaire. The score assigned to the procedural pain on a 0-10 scale was higher than 5 in 77% of the operators for lumbar puncture, 97.5% for bone marrow aspiration, and 99.5% for bone marrow biopsy. The scores assigned by nurses differed statistically from those of the physicians and directors for the pain caused by lumbar puncture and bone marrow aspiration. Measures adopted for procedural pain control were generally considered good.

Conclusions

Invasive diagnostic-therapeutic procedures performed in Italian Pediatric Hemato-Oncology Units are considered painful by all the caregivers involved. Pain management is generally considered good. Aprioristically opinions about pain depend on invasiveness of the procedure and on the professional role.

Perspectives on pain and intellectual disability

Historically, individuals with intellectual disability (ID) have been excluded from pain research and assumed to be insensitive or indifferent to pain. The weight of the evidence suggests that individuals with ID have been subject to practices and procedures with little regard for their ability to experience or express pain. A number of issues central to improving understanding of pain in ID will be introduced and current research related to the definition of pain and its social context, underlying sensory and metabolic systems and factors influencing judgments about the ability to experience pain will be reviewed. Accumulating evidence from interdisciplinary research designed to improve assessment, understand individual differences, and evaluate bias and beliefs about pain suggests that new perspectives are emerging and beginning to shape an innovative frontier of research that will ultimately pay tremendous dividends for improving the quality of life of individuals with ID.

The evaluation of acute pain in individuals with cognitive impairment: A differential effect of the level of impairment

The present study investigated whether the level of cognitive impairment (CI) affects acute pain behavior and how it is manifested. Participants were 159 individuals (mean age 42+/-12), 121 with CI (divided into four groups according to the level of CI: mild, moderate, severe, profound) and 38 with normal cognition (controls). The behavior of the participants before and during acute pain (influenza vaccination) was coded by two raters with the Facial Action Coding System (FACS - scores facial reactions to pain) and the Non-Communicating Children's Pain Checklist (NCCPC-R - scores both facial and general body reactions). Individuals with severe-profound CI exhibited elevated FACS and NCCPC-R values at baseline compared with all other groups (p<0.01). Both FACS and NCCPC-R scores of individuals with mild-moderate CI and controls increased significantly during vaccination (p<0.001). In contrast, individuals with severe-profound CI exhibited high rates of "freezing reaction" (stillness) during vaccination, manifested mainly in the face and therefore resulting in elevation of only NCCPC-R scores but not of FACS's. The results suggest that the level of CI affects baseline as well as pain behavior and it is therefore necessary to choose an appropriate behavioral tool to measure pain in these individuals accordingly. For example, tools based on facial reactions alone might provide the false impression that individuals with severe-profound CI are insensitive to pain (due to freezing).

Judgments of pain in the neonatal intensive care setting: a survey of direct care staffs' perceptions of pain in infants at risk for neurological impairment

OBJECTIVE

To determine whether healthcare professionals believe the pain of infants at risk for neurologic impairment differs from that of typical infants.

SETTING

Neonatal intensive care units at 2 tertiary pediatric centers in Canada.

PARTICIPANTS

Ninety-nine healthcare professionals who practice in the neonatal intensive care unit (51 nurses, 19 physicians, 18 respiratory therapists, 11 other). MAJOR MEASURES: Participants completed the Pain Opinion Questionnaire. It elicits beliefs regarding the similarity of the pain experienced by infants at mild, moderate, and severe risk for neurologic impairment relative to those without risk for neurologic impairment along 5 pain facets (ie, sensation, emotional reaction, behavioral reaction, communication, incidence).

RESULTS

Pain Opinion Questionnaire scores varied by level of risk of neurologic impairment (mild, moderate, severe) and pain facet. Respondents believed infants with risk were overall less likely to experience pain similar to infants without risk as the level of risk increased [F(2,97) = 66.0, P < 0.001] and were more likely to have a reduced pain experience relative to infants without risk as the level of risk increased [F(2,97) = 62.2, P < 0.001]. Pain Opinion Questionnaire scores did not vary due to profession, experience, gender, or age.

CONCLUSION

Professionals expressed the belief that neurologically impaired infants' pain experience is reduced, relative to infants without impairment, as their level of risk for neurologic impairment increases. This belief did not vary due to professional experience or personal factors. Future studies should investigate the source of these beliefs and their impact on the pain management provided to infants with risk for neurologic impairment.

Congenital indifference to pain and deletion of chromosome 10q-: new association

We describe a case of a de novo terminal deletion of the long arm of chromosome 10 with the novel feature of congenital indifference to pain in a 2-year 10-month-old boy. Relative indifference to pain defined by a lack of emotional response to pain has not been described previously in association with the terminal deletion of the long arm of chromosome 10.

Assessment in intellectual disability

PURPOSE OF REVIEW

This review examines an eclectic selection of publications from the past 12 months under the broad heading of 'assessment in intellectual disability'. Being unable to cover all possible publications the authors have concentrated on the assessment of pain (in those with severe intellectual disability), psychopathology, risk assessment and offending, autism, preference and choice, and dementia.

RECENT FINDINGS

Research into assessment has generally taken the form of developing new instruments, or adapting existing ones, or comparing the performance of a range of scales in a certain area. Researchers are using increasingly sophisticated psychometric analyses and refining the nature and purpose of tools for a range of clinical purposes.

SUMMARY

The result of recent effort in this area is better instruments, often developed by experienced researchers who have been working in their chosen area of speciality for some years. It has been a very worthwhile period of extension and consolidation.

Healthcare professionals' perceptions of pain in infants at risk for neurological impairment

BACKGROUND

To determine whether healthcare professionals perceive the pain of infants differently due to their understanding of that infant's level of risk for neurological impairment.

METHOD

Neonatal Intensive Care Units (NICU's) at two tertiary pediatric centers. Ninety-five healthcare professionals who practice in the NICU (50 nurses, 19 physicians, 17 respiratory therapists, 9 other) participated. They rated the pain (0-10 scale and 0-6 Faces Pain Scale), distress (0-10), effectiveness of cuddling to relieve pain (0-10) and time to calm without intervention (seconds) for nine video clips of neonates receiving a heel stick. Prior to each rating, they were provided with descriptions that suggested the infant had mild, moderate or severe risk for neurological impairment. Ratings were examined as a function of the level of risk described.

RESULTS

Professionals' ratings of pain, distress, and time to calm did not vary significantly with level of risk, but ratings of the effectiveness of cuddling were significantly lower as risk increased [F (2,93) = 4.4, p = .02]. No differences in ratings were found due to participants' age, gender or site of study. Physicians' ratings were significantly lower than nurses' across ratings.

CONCLUSION

Professionals provided with visual information regarding an infants' pain during a procedure did not display the belief that infants' level of risk for neurological impairment affected their pain experience. Professionals' estimates of the effectiveness of a nonpharmacological intervention did differ due to level of risk.

Risk factors for pain in children with severe cognitive impairments

Diagnosing cause of pain in children with severe cognitive impairments is difficult due to their problems with communication. Identification of risk factors for specific pain etiologies might help professionals in this task. The aim of this study was to determine whether child-related characteristics increase risk for specific types of pain. Participants were the caregivers of 41 females and 53 males with moderate to profound mental retardation, who were aged 3 to 18 years 8 months (mean 10:1, SD 4:4) but who communicated at the level of a typical child of 13.8 months (SD 10 months): 44 of the children had cerebral palsy (CP) and 59 a seizure disorder. Caregivers reported the cause of children's episodes of pain for four 1-week periods over 1 year. Logistic regression analyses were used to predict occurrence of specific types of pain using children's demographic, medical, and physical characteristics. Children had 406 episodes of pain due to accident, gastrointestinal conditions, musculoskeletal problems, infection, recurrent conditions, and common childhood causes. Results indicated that a unique set of risk factors predicted each pain type in this sample. Significant risk factors for pain included: lack of visual impairment and leg impairment (accidental pain); seizures, leg impairment, and greater number of medications (non-accidental pain); being male and tube fed (musculoskeletal pain); age <7 years, absence of CP, visual impairment, and less frequent medical monitoring (infection pain); being female and with arm impairment (gastrointestinal pain); and being tube fed and taking fewer medications (common childhood pains). In most cases, models were more specific than sensitive, indicating that the significant predictors are more useful for eliminating potential pain causes. These results suggest that population risk factors may be helpful in structuring diagnostic investigations for individual children with severe cognitive impairments.
