Parents as distraction coaches during i.v. insertion: a randomized study

Training healthcare professionals in hypnosis-derived communication to mitigate procedural pain in children

How professionals communicate during medical procedures may have a significant impact on children and adolescents' pain. Rel@x is a manualized training program designed to develop hypnosis-derived communication skills to mitigate childhood pain and distress. The study aimed to evaluate if this training was associated with an improvement and maintenance in communication skills over time, and measure associations between changes and participants' characteristics. A 9-hour training in hypnosis-derived communication was offered to 78 volunteer healthcare professionals from a tertiary pediatric hospital, and 58 participated in the evaluative study. Participants were evaluated at baseline, immediately after training, and 5 months later (39 ± 10 yrs, 52 women, 54 nurses). We used a video-recorded standardized simulation protocol of blood draw and coded the participants' interactions with the pre-validated Sainte-Justine Hypnotic Communication Assessment Scale (SJ-HCAS) assessing relational, technical, and total skills. We modeled pre-post-follow-up changes over time with latent growth curve models. Satisfaction with Rel@x was consistently excellent (97%). Across the 3 domains, we observed significant improvements of total (+ 61%, 95% CI 53-69%), relational (+ 27%, 95% CI 20-34%), and technical skills (+ 124%, 95% CI 08-140%). Post-training competence levels were 73-91% across domains. A large proportion of acquired skills were maintained at 5 months (55-75%) suggesting a significant effect of the training. Sensitivity analyses confirmed these results (best-case/worst-case skill maintenance ratio: 59-79%/49-73%). Larger improvements in technical skills were associated with younger age and lower baseline skills of participants. The Rel@x training is associated with improved skills in hypnotic communication post-training and at follow-up. This simulation study paves the way for future efficacy studies to examine the effect of hypnotic communication on real patients' pain and distress.

Affective and social pain modulation in children-Experimental evidence using picture viewing

BACKGROUND

Children frequently encounter pain. Their pain like adults' pain is probably modulated by social-affective factors. Despite its clinical relevance, such pain modulation has not been explored experimentally in children, and little is known about specific factors accounting for it such as catastrophizing. We examined pain modulating effects of pictures varying in social-affective content and personal meaning (e.g., mothers' vs. strangers' faces) using subjective and psychophysiological measures (skin conductance, heart rate, corrugator electromyography) as outcomes.

METHODS

Forty-two children (8-13 years) underwent tonic heat pain stimulation while viewing pictures (social-affective: their mothers' faces with neutral expression, strangers' neutral and happy faces; affective: positive and negative scenes). Furthermore, the contribution of children's characteristics (e.g., anxiety, catastrophizing) and facets of the parent-child relationship to pain modulation was determined.

RESULTS

Viewing mothers' faces or positive scenes reduced subjective pain intensity and corrugator activity in response to pain. Viewing happy strangers' faces lowered corrugator activity. Enhanced pain experience due to negative affective stimuli was primarily observed psychophysiologically. The correlation between children's tendency to catastrophize and pain relief by mothers' faces was mediated by induced arousal, likely reflecting the degree of motivational activation of seeking social support.

CONCLUSIONS

Pain relief by positive affective and social-affective stimuli extends previous findings in adults, especially regarding reduced pain-related facial muscle activity. Moreover, the results shed light on the interplay between catastrophizing and social context on children's pain experience. Clinically, our results imply that just looking at pictures of their mothers (or positive scenes) might help to alleviate pain in children.

Comparison of Animation Distraction Versus Local Anesthetic Application for Pain Alleviation in Children Undergoing Intravenous Cannulation: A Randomized Controlled Trial

Background Medical procedures induce behavioral discomfort, fear, and worry in children and their families, worsening their agony. Reading, playing video games, and watching television lessen anxiety and discomfort. This study aims to compare the pain reduction in children using animation distraction and two percent lignocaine with the control group undergoing intravenous (IV) cannulation using the Visual Analogue Scale (VAS) at a tertiary care hospital in Kolenchery, Kerala, South India, and to study the clinico-social factors influencing pain reduction in children undergoing IV cannulation. Materials and methods This is an open-label, randomized controlled trial study of 60 children admitted in a pediatric ward, Intensive Care Unit (ICU), or emergency department randomly assigned to either two percent lignocaine application, animation distraction, or control during intravenous cannulation. Children aged six to twelve years requiring IV cannulation for different illnesses were included. Twenty children were randomly assigned to the lignocaine group, twenty to the distraction group, and twenty to the control group. The visual analogue scale was used to measure the subjective pain intensity of the children during IV cannulation. We did statistical analysis using SPSS software version 21 (IBM Corp., Armonk, NY). Results Age, gender, previous history of cannulation, site, and size of the cannula were not significantly different between the groups. We did not relate the education of the mother to the VAS scores. The mean VAS score for pain at zero, one, and five minutes was lower in the distraction group compared to the lignocaine and control groups. The mean VAS score for pain at zero, one, and five minutes was not superior among the lignocaine group compared to the control group. Conclusion Based on the findings, animation distraction is preferable to lignocaine to alleviate pain in children requiring IV cannulation for a variety of disorders. Distraction is one of the nonpharmacological techniques that seek to alleviate pain by encouraging the patient to focus on something other than the current procedure. In addition to reducing pain and anxiety during excruciating invasive interventions, distraction techniques reduce the number of interventions required and allow for the completion of interventions in less time.

Infrared augmented reality device versus standard procedure for peripheral venous catheterisation in children less than 3 years old: A quasi-experimental cluster randomised controlled trial

AIM AND OBJECTIVE

The objective of this study was to evaluate the AccuVeinAV400® viewing device for peripheral venous catheter insertion in children on the first try.

BACKGROUND

Inserting a peripheral venous catheter is the most frequent invasive procedure carried out by healthcare professionals in hospitalised children. Several attempts are sometimes necessary, and veins can be damaged.

DESIGN

A quasi-experimental cluster randomised controlled trial based on the CONSORT 2010 guidelines.

METHODS

This randomised study comparing standard practice to the use of AccuVein400^® was carried out on children who were less than 3 years old, with difficult intravenous access (DIVA Score), hospitalised in three paediatric units and who needed cannulation.

RESULT

A total of 304 children were included (156 in the AccuVein arm and 148 in the standard arm). There was no significant difference between AccuVein and standard groups in age (respectively, 2.5 ± 0.9 years vs. 2.5 ± 0.8), or mean DIVA score (respectively 5.9 ± 1.3 vs. 5.5 ± 1.2). The success of cannulation on the first attempt was 40.38% in the AccuVein arm vs. 41.2% in the standard arm (p = .6). The caregiver's assessment of pain on the Face Legs Activity Cry Consolability scale was 4.8 ± 0.2 in the AccuVein arm vs. 5.0 ± 0.2 (p = .4).

CONCLUSIONS

The use of AccuVein400® did not lead to greater success in intravenous insertion at the first attempt in children under 3 years of age with difficult intravenous access.

RELEVANCE TO CLINICAL PRACTICE

This device can therefore be used according to the healthcare professionals' situation and needs. It is widely used in paediatric wards, and our study shows that it offers a support tool that reassures healthcare professionals and helps validate their choice of vein easiest to catheterise.

Tablet Computer as a Distraction Tool During Facial Laceration Repair: A Randomized Trial

OBJECTIVES

Child life interventions reduce the anxiety of medical procedures but are not always available in emergency departments. In this study, we determined the effect of parent-directed tablet computer use without child life direction on patient anxiety and on parent and suturing clinician experience during pediatric facial laceration repair.

METHODS

In a children's hospital emergency department, we enrolled children 2 to 12 years of age undergoing unsedated facial laceration repairs and randomized them to parent-directed tablet computer distraction or standard supportive care. We measured anxiety using the Observational Scale of Behavioral Distress-Revised (OSBD-R) for 5 procedure phases from videotaped laceration repairs. We compared OSBD-R scores for 5 phases and weighted averages between the tablet and standard care groups. Parents and suturing clinicians completed surveys about their experiences after the procedures.

RESULTS

From April 2014 to July 2015, 77 patients (39 tablet, 38 standard) underwent repairs. Age, use of restraint, procedure duration, and number of sutures were similar between the 2 groups. The groups did not differ in procedure phase or weighted-average OSBD-R scores. Parents in the tablet group reported less personal anxiety compared with parents in the standard group (P = 0.01). In a post hoc subgroup analysis, subjects in the unrestrained tablet group had lower OSBD-R scores during the anesthetic injection phase than did subjects in the unrestrained standard group (P = 0.04). If restrained, subjects in the tablet group had higher OSBD-R scores during the anesthetic injection phase than did subjects in the standard group (P = 0.048).

CONCLUSIONS

Unrestrained children may benefit from parent-directed tablet computer distraction. Parents who operate the device are less anxious during their children's procedures.

Clinical Holding in Pediatric Venipuncture: Caring by Empowering the Caregiver

The use of restraint in the child-adolescent population is highly controversial due to the consequences it can have for patients and their families, although it is sometimes necessary to employ restraint to perform techniques safely and effectively. Clinical Holding is committed to the involvement of parents during venipuncture in the context of family-centred care. This study assesses levels of distress and pain in children undergoing this procedure, as well as satisfaction in parents and nurses. Parents assist in the restraint of children and provide accompaniment during venipuncture. Levels of distress and pain were not particularly elevated. Satisfaction levels among parents and nurses were high. A positive correlation was found between anticipatory and real distress (r = 0.737, p = 0.000), and between real distress and real pain (r = 0.368, p = 0.035). A negative correlation was observed between real pain and parent satisfaction (r = -0.497, p = 0.003). Parental participation during venipuncture contributed to better management of distress and pain. In the future, it would be advisable to incorporate the other pharmacological and non-pharmacological measures recommended by Clinical Holding to ensure care of the highest quality and safety.

Play and medical play in teaching pre-school children to cope with medical procedures involving needles: A systematic review

AIM

Most toddlers experience pain and distress during doctor or dental visits. Aim of this systematic review was to investigate the role of play-based interventions in pain and fear or distress management in pre-school children (aged from 2 to 6 years old) undergoing needle-related medical procedures adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (registration number: CRD42020192161).

METHODS

The key database that was searched was PubMed/MEDLINE along with references of relevant review studies. Only randomised controlled trials (RCTs) that fulfilled inclusion and eligibility criteria were selected for analysis. Methodological quality was evaluated using the Cochrane Collaboration's Risk of Bias Tool for RCTs and Review Manager version 5.4 was utilised in order to calculate standardised mean differences (SMDs) and create a forest plot for included studies that presented data on self-reported pain ratings. Primary outcomes refer to pain, anxiety and fear assessments, while secondary outcomes refer to physiological measures and cortisol levels.

RESULTS

All included RCTs suffered from high risk of bias that relied on selection and blinding methodology, while other sources of bias were also present in some cases. Despite low-quality of evidence, play-based interventions seem to favour less self-reported pain (SMD -0.39; 95% CI: -0.67 to -0.12; I² = 84%).

CONCLUSION

Limitations of evidence, except from high risk of bias, include inconsistency in reporting primary outcome assessments and study designs that preclude reproducibility. Play-based techniques seem to contribute to pre-schoolers' coping towards needle-related medical procedures and further research is warranted in order to explore clinical benefits.

Influence of parent-provided distraction and interactive distraction with a handheld video game on the child's responses during local anesthesia administration

BACKGROUND

To evaluate the influence of parent-provided distraction (PPD) and interactive distraction (ID) with a handheld video game (HVG) on the child's responses to local anesthesia (LA) administration during dental treatment.

METHODS

Children attending the department of pediatric dentistry were randomly selected and distributed to the two groups (PPD and an ID with HVG). Parents in the operatory and the principles of tell-show-do remained common in both the groups. Behavioral, physiological, and self-report measures of pain were estimated using the Face, Legs, Activity, Cry, and Consolability (FLACC) scale, pulse rate, as well as Iowa pain thermometer-revised (IPT-R) scale and compared for both groups correspondingly. The SPSS (standard statistical package) version 17.0 (SPSS Inc., Chicago, USA) was used for statistical analysis at the significance of P < 0.05.

RESULTS

A total of 30 children (15 in each group) aged 7-11 years participated in the study. There were no significant differences observed among boys and girls (P > 0.05). The independent t-test for the pulse rate showed no significant difference between the two groups (P > 0.05). Paired t-test for pulse rate in the PPD group showed a significant difference compared to ID with the HVG group (P < 0.05). The scores for FLACC and ID with HVG, showed a statistically significant decrease in scores recorded for ID with HVG, whereas the scores recorded for FLACC did not show any statistically significant difference.

CONCLUSION

Based on the study results, PPD would be the least distressful option, compared to the ID with HVG in children while administering LA.

Study protocol for a randomized controlled trial of a child and parent mindfulness intervention for pediatric venipuncture

Children commonly undergo painful needle procedures. Unmanaged procedural pain can have short‐ and long‐term consequences, including longer procedure times, greater distress at future procedures, and vaccine hesitancy. While parent behaviors are one of the strongest predictors of children's response to acute pain, pediatric procedural pain management interventions focus almost exclusively on the child. Further, existing parent‐involved pediatric pain management interventions typically fail to improve child self‐reported pain during painful procedures. The current protocol offers the first randomized controlled trial involving a mindfulness intervention for pediatric acute pain that includes children and their parents. This study aims to conduct a single‐site, two‐arm, parallel‐group RCT to examine the effects of a mindfulness intervention for parents and children before child venipuncture compared to a control group on primary (child self‐report of pain and fear), secondary (parent self‐report and child report of parent distress), and tertiary outcomes (parent report of child pain and fear). Parent‐child dyads (n = 150) will be recruited from the McMaster Children's Hospital outpatient blood laboratory. Dyads will be randomly assigned to either a mindfulness group guided through a mindfulness intervention or control group guided through an unfocused attention task. Parents will accompany their child for their venipuncture. Postvenipuncture measures will be collected (eg, child pain‐related outcomes as reported by parents and children). The first enrollment occurred in October 2019. We offer a novel intervention that aims to facilitate both parent and child coping during child venipuncture.

The current protocol offers the first randomized controlled trial involving a mindfulness intervention for pediatric acute pain that includes children and their parents.

We offer a novel intervention that aims to facilitate both parent and child coping during child venipuncture.

Anxiety and Salivary Cortisol Levels in Children Undergoing Esophago-Gastro-Duodenoscopy Under Sedation

OBJECTIVES

Esophagogastroduodenoscopy (EGD) can cause fear and anxiety in children. Cortisol, which is the most important glucocorticoid hormone in humans, can increase under physiological stress. The purpose of this study was to measure the salivary cortisol level (SCL) and anxiety level in patients undergoing EGD and evaluate their effects on the procedure.

METHODS

Children undergoing EGD under sedoanalgesia with propofol for various reasons were included. Their basal SCLs were compared with those of healthy age- and sex-matched controls. Moreover, SCL of the patient group at 30 minutes before EGD and 2 hours after the procedure were measured. Their anxiety scores were calculated using the modified Yale Preoperative Anxiety Scale before EGD. Duration of endoscopy, sedation, and recovery and total propofol doses were recorded.

RESULTS

Demographic properties of the patient group (n = 119; 10.9 ± 3.2 years; 43.7% boys) and control group (n = 85; 11.8 ± 2.8 years; 45.1% boys) were not significantly different. Basal SCLs of both groups were similar (16.9 ± 0.7 vs 19.7 ± 1.8 ng/mL, P = 0.16). SCL before EGD in the patient group was significantly higher than basal and post-EGD values (P < 0.001 for each). Pre-EGD SCL was positively correlated with anxiety level, propofol dose, and duration of sedation, procedure, and recovery. Anxiety levels of patients were positively correlated with propofol dose and duration of sedation and recovery, and negatively correlated with age.

CONCLUSIONS

Childhood EGD is a significant stress factor, which was reflected by the pre-procedural SCL in this study. Increased anxiety resulted in increased propofol doses and sedoanalgesia-related procedural durations, which may cause potential complications.

Psychological interventions for needle-related procedural pain and distress in children and adolescents

BACKGROUND

This is the second update of a Cochrane Review (Issue 4, 2006). Pain and distress from needle-related procedures are common during childhood and can be reduced through use of psychological interventions (cognitive or behavioral strategies, or both). Our first review update (Issue 10, 2013) showed efficacy of distraction and hypnosis for needle-related pain and distress in children and adolescents.

OBJECTIVES

To assess the efficacy of psychological interventions for needle-related procedural pain and distress in children and adolescents.

SEARCH METHODS

We searched six electronic databases for relevant trials: Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; PsycINFO; Embase; Web of Science (ISI Web of Knowledge); and Cumulative Index to Nursing and Allied Health Literature (CINAHL). We sent requests for additional studies to pediatric pain and child health electronic listservs. We also searched registries for relevant completed trials: clinicaltrials.gov; and World Health Organization International Clinical Trials Registry Platform (www.who.int.trialsearch). We conducted searches up to September 2017 to identify records published since the last review update in 2013.

SELECTION CRITERIA

We included peer-reviewed published randomized controlled trials (RCTs) with at least five participants per study arm, comparing a psychological intervention with a control or comparison group. Trials involved children aged two to 19 years undergoing any needle-related medical procedure.

DATA COLLECTION AND ANALYSIS

Two review authors extracted data and assessed risks of bias using the Cochrane 'Risk of bias' tool. We examined pain and distress assessed by child self-report, observer global report, and behavioral measurement (primary outcomes). We also examined any reported physiological outcomes and adverse events (secondary outcomes). We used meta-analysis to assess the efficacy of identified psychological interventions relative to a comparator (i.e. no treatment, other active treatment, treatment as usual, or waitlist) for each outcome separately. We used Review Manager 5 software to compute standardized mean differences (SMDs) with 95% confidence intervals (CIs), and GRADE to assess the quality of the evidence.

MAIN RESULTS

We included 59 trials (20 new for this update) with 5550 participants. Needle procedures primarily included venipuncture, intravenous insertion, and vaccine injections. Studies included children aged two to 19 years, with few trials focused on adolescents. The most common psychological interventions were distraction (n = 32), combined cognitive behavioral therapy (CBT; n = 18), and hypnosis (n = 8). Preparation/information (n = 4), breathing (n = 4), suggestion (n = 3), and memory alteration (n = 1) were also included. Control groups were often 'standard care', which varied across studies. Across all studies, 'Risk of bias' scores indicated several domains at high or unclear risk, most notably allocation concealment, blinding of participants and outcome assessment, and selective reporting. We downgraded the quality of evidence largely due to serious study limitations, inconsistency, and imprecision.Very low- to low-quality evidence supported the efficacy of distraction for self-reported pain (n = 30, 2802 participants; SMD -0.56, 95% CI -0.78 to -0.33) and distress (n = 4, 426 participants; SMD -0.82, 95% CI -1.45 to -0.18), observer-reported pain (n = 11, 1512 participants; SMD -0.62, 95% CI -1.00 to -0.23) and distress (n = 5, 1067 participants; SMD -0.72, 95% CI -1.41 to -0.03), and behavioral distress (n = 7, 500 participants; SMD -0.44, 95% CI -0.84 to -0.04). Distraction was not efficacious for behavioral pain (n = 4, 309 participants; SMD -0.33, 95% CI -0.69 to 0.03). Very low-quality evidence indicated hypnosis was efficacious for reducing self-reported pain (n = 5, 176 participants; SMD -1.40, 95% CI -2.32 to -0.48) and distress (n = 5, 176 participants; SMD -2.53, 95% CI -3.93 to -1.12), and behavioral distress (n = 6, 193 participants; SMD -1.15, 95% CI -1.76 to -0.53), but not behavioral pain (n = 2, 69 participants; SMD -0.38, 95% CI -1.57 to 0.81). No studies assessed hypnosis for observer-reported pain and only one study assessed observer-reported distress. Very low- to low-quality evidence supported the efficacy of combined CBT for observer-reported pain (n = 4, 385 participants; SMD -0.52, 95% CI -0.73 to -0.30) and behavioral distress (n = 11, 1105 participants; SMD -0.40, 95% CI -0.67 to -0.14), but not self-reported pain (n = 14, 1359 participants; SMD -0.27, 95% CI -0.58 to 0.03), self-reported distress (n = 6, 234 participants; SMD -0.26, 95% CI -0.56 to 0.04), observer-reported distress (n = 6, 765 participants; SMD 0.08, 95% CI -0.34 to 0.50), or behavioral pain (n = 2, 95 participants; SMD -0.65, 95% CI -2.36 to 1.06). Very low-quality evidence showed efficacy of breathing interventions for self-reported pain (n = 4, 298 participants; SMD -1.04, 95% CI -1.86 to -0.22), but there were too few studies for meta-analysis of other outcomes. Very low-quality evidence revealed no effect for preparation/information (n = 4, 313 participants) or suggestion (n = 3, 218 participants) for any pain or distress outcome. Given only a single trial, we could draw no conclusions about memory alteration. Adverse events of respiratory difficulties were only reported in one breathing intervention.

AUTHORS' CONCLUSIONS

We identified evidence supporting the efficacy of distraction, hypnosis, combined CBT, and breathing interventions for reducing children's needle-related pain or distress, or both. Support for the efficacy of combined CBT and breathing interventions is new from our last review update due to the availability of new evidence. The quality of trials and overall evidence remains low to very low, underscoring the need for improved methodological rigor and trial reporting. Despite low-quality evidence, the potential benefits of reduced pain or distress or both support the evidence in favor of using these interventions in clinical practice.

Development and inter-rater reliability of a tool assessing hypnotic communication behaviours adopted by nurses caring for children with cancer: The Sainte-Justine Hypnotic Communication Assessment Scale

BACKGROUND

Several studies in pediatric oncology have shown the successful effects of using hypnotic communication techniques (HCTech) during painful medical procedures. Since no studies assessed the precise use of these techniques with a validated tool, it is unsure that the observed relationships involve the use of HCTech.

OBJECTIVES

To develop a scale evaluating healthcare professionals' behaviours when using HCTech and to evaluate its inter-rater reliability.

METHODS

This study involved the preliminary steps of the Sainte-Justine Hypnotic Communication Assessment Scale (SJ-HCAS) development process. As part of a larger intervention study, the SJ-HCAS was developed in three steps by five experts and four lay raters using an iterative process applied to subsets of video-recorded nurse-patient interactions. The development aimed to maximize clarity and precision of items as well as minimize redundancy amongst items. Inter-rater reliability was assessed in a randomly selected sample of 1/3 of collected video-recorded interactions (n=42).

RESULTS

The final version of the scale is composed of 11 items categorized in two domains pertaining to Relationship and Technique. We found excellent inter-rater reliability for both subscores and total score in two independent inter-rater comparisons (median ICC=0.879), with most items showing very good to perfect inter-rater reliability (median Kappa=0.847).

CONCLUSIONS

The results support further work with the SJ-HCAS. The scale has the potential to help ensure the integrity of hypnotic communication training in children which could ultimately promote the dissemination of the practice of HCTech.

Distraction-Based Interventions for Children Undergoing Venipuncture Procedures: A Randomized Controlled Study

Little is known about the effects of distraction techniques when undertaking medical procedures with hospitalized pediatric patients in Asian countries. This study examined the effects of distraction interventions on behavioral distress related to venipuncture procedures in Taiwanese children aged 3 to 7 years. Using concealed randomization, eligible children were allocated to receive a picture book ( n = 92), or animated cartoon ( n = 92) compared with routine oral instructions ( n = 92), when being injected with an intravenous cannula. Two trained observers independently scored the responses of each child using the Observational Scale of Behavioral Distress-Revised before, during, and after the procedure. All children experienced distress during needle insertion, but distress was less in the distraction-based intervention groups. Moreover, distraction interventions were more effective for children aged 4 to 5 years. Our culturally tailored intervention engaged child participants, was age-appropriate, and could be adapted for use in other Chinese cultures.

Nursing management of children's pain: Current evidence and future directions for research

This critical literature review discusses the research evidence underpinning each of the pain standards in the National Service Framework for Children: Standard for hospital services. Relevant evidence-based reviews and clinical practice guidelines are highlighted, and aspects of children's pain management where the research evidence is particularly strong or weak are identified. Priorities are suggested for nurse-led research aimed at generating new knowledge to improve pain management for children.

Holistic Comfort Interventions for Pediatric Nursing Procedures: A Systematic Review

Comfort interventions for children during invasive nursing procedures have been well documented in the literature. It is important, however, to distinguish between the provision of holistic comfort management and pain alleviation. Holistic comfort focuses on treating the child’s whole procedural experience and includes more than simply reducing pain. In this literature review, 33 intervention studies were examined. These studies focused on evaluating comfort effects from nursing interventions on pain, anxiety, fear, and distress. Four themes of procedural comfort intervention emerged: music therapy, amusement and entertainment, caregiver facilitation, and a multifaceted approach. Important findings of this review, gaps in the literature, and implications for future research are discussed.

Matching doses of distraction with child risk for distress during a medical procedure: a randomized clinical trial

BACKGROUND

Parents often want to provide support to their children during medical procedures, but not all parents are effective in providing distraction after brief training.

OBJECTIVE

The aim of this study was to investigate the effects of three doses of distraction intervention for children at high and medium risk for procedure-related distress.

METHODS

Children undergoing scheduled intravenous insertions for diagnostic or treatment purposes and their parents participated. A computerized application, Children, Parents and Distraction, was used to predict distress risk. Doses of intervention were basic (parents trained on providing distraction), enhanced (basic training plus tailored instructions, environmental modifications, and support and guidance from the research assistant), and professional (a trained research assistant provided distraction). Outcome measures were Observational Scale of Behavioral Distress-Revised for behavioral distress, Oucher for self-reported pain, parent report of child distress, and salivary cortisol for physiological distress.

RESULTS

A total of 574 children, ages 4-10, and their parents participated. The Children, Parents and Distraction predicted that the risk for distress was high for 156 children, medium for 372, and low for 46. Children predicted to have higher risk for distress displayed more behavioral distress (p < .01). Children in the medium-risk group who had the professional intervention displayed significantly less behavioral distress (p < .001). Children in the high-risk group tended to have less behavioral distress when receiving the professional intervention (p = .07). There were no significant group differences for self-report of pain, parent report of distress, or cortisol levels.

DISCUSSION

Some parents may need additional training in providing distraction to their children during procedures, and some children at medium and high risk for distress may need professional support. Parents should be asked about their preferences in acting as the distraction coach and, if willing, be provided as much training and support as possible in the clinical situation.

Nurses' provision of parental guidance regarding school-aged children's postoperative pain management: a descriptive correlational study

Involving parents in children's pain management is essential to achieve optimal outcomes. Parents need to be equipped with sufficient knowledge and information. Only a limited number of studies have explored nurses' provision of parental guidance regarding the use of nonpharmacologic methods in children's pain management. This study aimed to examine nurses' perceptions of providing preparatory information and nonpharmacologic methods to parents, and how their demographics and perceived knowledge adequacy of these methods influence this guidance. A descriptive correlational study using questionnaire surveys was conducted to collect data from a convenience sample of 134 registered nurses working in seven pediatric wards of two public hospitals in Singapore. Descriptive statistics, independent-samples t test, and multiple linear regression were used to analyze the data. Most nurses provided various types of cognitive information to parents related to their children's surgery, whereas information about children's feelings was less often provided. Most nurses provided guidance to parents on positioning, breathing technique, comforting/reassurance, helping with activities of daily living, relaxation, and creating a comfortable environment. Nurses' provision of parental guidance on preparatory information and nonpharmacologic methods was significantly different between subgroups of age, education, parent or not, and perceived knowledge adequacy of nonpharmacologic methods. Nurses' perceived knowledge adequacy was the main factor influencing their provision of parental guidance. More attention should be paid to nurses who are younger, have less working experience, and are not parents. There is a need to educate nurses about nonpharmacologic pain relief methods to optimize their provision of parental guidance.

Systematic review and meta-analysis of distraction and hypnosis for needle-related pain and distress in children and adolescents

OBJECTIVE

To systematically review the evidence (and quality) for distraction and hypnosis for needle-related pain and distress in children and adolescents. To explore the effects of distraction characteristics (e.g., adult involvement, type of distracter), child age, and study risk of bias on treatment efficacy. 

METHODS

26 distraction and 7 hypnosis trials were included and self-report, observer-report, and behavioral pain intensity and distress examined. Distraction studies were coded for 4 intervention characteristics, and all studies coded for child age and study risk of bias. 

RESULTS

Findings showed strong support for distraction and hypnosis for reducing pain and distress from needle procedures. The quality of available evidence was low, however. Characteristics of distraction interventions, child age, and study risk of bias showed some influence on treatment efficacy.

CONCLUSIONS

Distraction and hypnosis are efficacious in reducing needle-related pain and distress in children. The quality of trials in this area needs to be improved.

A Delphi study to identify indicators of poorly managed pain for pediatric postoperative and procedural pain

BACKGROUND

Adverse health care events are injuries occurring as a result of patient care. Significant acute pain is often caused by medical and surgical procedures in children, and it has been argued that undermanaged pain should be considered to be an adverse event. Indicators are often used to identify other potential adverse events. There are currently no validated indicators for undertreated pediatric pain.

OBJECTIVES

To develop a preliminary list of indicators of undermanaged pain in hospitalized pediatric patients.

METHODS

The Delphi technique was used to survey experts in pediatric pain management and quality improvement. The first round used an electronic questionnaire to ask: "In your opinion, what indicators would signify that acute pain in a child has not been adequately controlled?" Responses were grouped together in semantically similar themes, providing a list of possible adverse event indicators. Using this list, an electronic questionnaire was developed for round&nbsp;2&nbsp;asking respondents to indicate the importance of each potential indicator.

RESULTS

All but one indicator achieved a level of consensus ≥70%. Separate indicators emerged for postoperative and procedural pain. An additional distinction was made between indicators that could be identified by chart review and those requiring observation of practice and assessment from the child or parent.

DISCUSSION

The adverse care indicators developed in the present study require further refinement. There is a need to test their clinical usability and to determine whether these indicators actually identify undermanaged pain in clinical practice. The present study is an important first step in identifying undermanaged pain in hospital and treating it as an adverse event.

CONCLUSION

The adverse care indicators developed in the present study are the first step in conceptualizing mismanaged pain as an adverse event.

Systematic review and meta-analysis of distraction and hypnosis for needle-related pain and distress in children and adolescents

OBJECTIVE

To systematically review the evidence (and quality) for distraction and hypnosis for needle-related pain and distress in children and adolescents. To explore the effects of distraction characteristics (e.g., adult involvement, type of distracter), child age, and study risk of bias on treatment efficacy. 

METHODS

26 distraction and 7 hypnosis trials were included and self-report, observer-report, and behavioral pain intensity and distress examined. Distraction studies were coded for 4 intervention characteristics, and all studies coded for child age and study risk of bias. 

RESULTS

Findings showed strong support for distraction and hypnosis for reducing pain and distress from needle procedures. The quality of available evidence was low, however. Characteristics of distraction interventions, child age, and study risk of bias showed some influence on treatment efficacy.

CONCLUSIONS

Distraction and hypnosis are efficacious in reducing needle-related pain and distress in children. The quality of trials in this area needs to be improved.

Psychological interventions for needle-related procedural pain and distress in children and adolescents

BACKGROUND

This review is an updated version of the original Cochrane review published in Issue 4, 2006. Needle-related procedures are a common source of pain and distress for children. Our previous review on this topic indicated that a number of psychological interventions were efficacious in managing pediatric needle pain, including distraction, hypnosis, and combined cognitive behavioural interventions. Considerable additional research in the area has been published since that time.

OBJECTIVES

To provide an update to our 2006 review assessing the efficacy of psychological interventions for needle-related procedural pain and distress in children and adolescents.

SEARCH METHODS

Searches of the following databases were conducted for relevant randomized controlled trials (RCTs): Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; EMBASE; PsycINFO; the Cumulative Index to Nursing and Allied Health Literature (CINAHL); and Web of Science. Requests for relevant studies were also posted on various electronic list servers. We ran an updated search in March 2012, and again in March 2013.

SELECTION CRITERIA

Participants included children and adolescents aged two to 19 years undergoing needle-related procedures. Only RCTs with at least five participants in each study arm comparing a psychological intervention group with a control or comparison group were eligible for inclusion.

DATA COLLECTION AND ANALYSIS

Two review authors extracted data and assessed trial quality and a third author helped with data extraction and coding for one non-English study. Included studies were coded for quality using the Cochrane Risk of bias tool. Standardized mean differences with 95% confidence intervals were computed for all analyses using Review Manager 5.2 software.

MAIN RESULTS

Thirty-nine trials with 3394 participants were included. The most commonly studied needle procedures were venipuncture, intravenous (IV) line insertion, and immunization. Studies included children aged two to 19 years, with the most evidence available for children under 12 years of age. Consistent with the original review, the most commonly studied psychological interventions for needle procedures were distraction, hypnosis, and cognitive behavioural therapy (CBT). The majority of included studies (19 of 39) examined distraction only. The additional studies from this review update continued to provide strong evidence for the efficacy of distraction and hypnosis. No evidence was available to support the efficacy of preparation and information, combined CBT (at least two or more cognitive or behavioural strategies combined), parent coaching plus distraction, suggestion, or virtual reality for reducing children's pain and distress. No conclusions could be drawn about interventions of memory alteration, parent positioning plus distraction, blowing out air, or distraction plus suggestion, as evidence was available from single studies only. In addition, the Risk of bias scores indicated several domains with high or unclear bias scores (for example, selection, detection, and performance bias) suggesting that the methodological rigour and reporting of RCTs of psychological interventions continue to have considerable room for improvement.

AUTHORS' CONCLUSIONS

Overall, there is strong evidence supporting the efficacy of distraction and hypnosis for needle-related pain and distress in children and adolescents, with no evidence currently available for preparation and information or both, combined CBT, parent coaching plus distraction, suggestion, or virtual reality. Additional research is needed to further assess interventions that have only been investigated in one RCT to date (that is, memory alteration, parent positioning plus distraction, blowing out air, and distraction plus suggestion). There are continuing issues with the quality of trials examining psychological interventions for needle-related pain and distress.

Validation of a clinically useful measure of children's state anxiety before medical procedures

PURPOSE

Assessment of children's anxiety in busy clinic settings is an important step in developing tailored interventions. This article describes the construct validation of the Children's Anxiety Meter-State (CAM-S), a brief measure of state anxiety.

DESIGN AND METHODS

Existing data were used to investigate the associations between child self-reports of anxiety, parent reports of child anxiety, and observed child distress during an intravenous procedure.

RESULTS

Children's (n = 421) CAM-S scores were significantly associated with all parent measures and observed distress ratings.

PRACTICE IMPLICATIONS

Findings support the use of the CAM-S for assessment of child anxiety in clinical settings.

Effect of distraction on children's pain during intravenous catheter insertion

PURPOSE

This study examined the effect of pressing a soft ball during intravenous catheter insertion (IVCI) on the intensity of pain in children ages 4-6 years.

DESIGN AND METHODS

In this quasi-experimental study, children in the intervention group were asked to press a soft ball with the opposite hand during IVCI and to immediately mark the Wong-Baker FACES Pain Rating Scale.

RESULTS

There was a significant difference in the intensity of pain between the control group (n = 30) and the intervention group (n = 30; p =.012).

PRACTICE IMPLICATIONS

Pressing a soft ball during IVCI may be an easily accessed, inexpensive, and effective technique to control or reduce pain in young children.

Relief of pain and anxiety in pediatric patients in emergency medical systems

Control of pain and stress for children is a vital component of emergency medical care. Timely administration of analgesia affects the entire emergency medical experience and can have a lasting effect on a child's and family's reaction to current and future medical care. A systematic approach to pain management and anxiolysis, including staff education and protocol development, can provide comfort to children in the emergency setting and improve staff and family satisfaction.

Singaporean nurses' provision of guidance to parents on non-pharmacological postoperative pain-relief methods: An educational intervention study

This study examined the impact of an educational intervention (booklet distribution and lectures) on Singaporean nurses' provision of guidance to parents on the use of non-pharmacological methods of pain relief for their child's postoperative pain. Using a quasi-experimental one-group pre- and post-test study design, 134 and 112 registered nurses completed the questionnaires pre- and post-test, respectively. More than 75% of the nurses "always" guided parents to use breathing techniques, relaxation, positioning, comforting/reassurance, helping with activities of daily living, and creating a comfortable environment in the pretest and touch, presence, and distraction in addition to the aforementioned methods in the post-test. The nurses' provision of guidance to parents on all non-pharmacological methods increased, but statistically significant increases only were found in relation to massage and positive reinforcement. The results suggested that the educational intervention had some impact on nurses' provision of guidance to parents on the use of non-pharmacological methods of pain relief for children's postoperative pain. Continuing education in pain management should be provided to nurses in order to equip them with the knowledge to improve their practice.

The influence of adult behaviors on child coping during venipuncture: a sequential analysis

The aim of this exploratory study was to investigate the influences of adult behaviors on child coping behaviors during venipunctures (VPs) in an emergency department. Observations of children and adults from 66 VPs were coded using a modified version of the Child-Adult Medical Procedure Interaction Scale and analyzed using sequential analysis. Results showed adult reassurance behavior promoted child distress behaviors, such as crying, as well as nondistress behaviors, such as information seeking; adult distraction behaviors promoted children's distraction, control, and coping behaviors; and children frequently ignored adult behaviors. Findings suggest further exploration of children's internal strategies for coping, such as appraisal, and clarifying the role of adult reassurance in child coping behaviors.

Factors explaining children's responses to intravenous needle insertions

BACKGROUND

Previous research shows that numerous child, parent, and procedural variables affect children's distress responses to procedures. Cognitive-behavioral interventions such as distraction are effective in reducing pain and distress for many children undergoing these procedures.

OBJECTIVES

The purpose of this report was to examine child, parent, and procedural variables that explain child distress during a scheduled intravenous insertion when parents are distraction coaches for their children.

METHODS

A total of 542 children, between 4 and 10 years of age, and their parents participated. Child age, gender, diagnosis, and ethnicity were measured by questions developed for this study. Standardized instruments were used to measure child experience with procedures, temperament, ability to attend, anxiety, coping style, and pain sensitivity. Questions were developed to measure parent variables, including ethnicity, gender, previous experiences, and expectations, and procedural variables, including use of topical anesthetics and difficulty of procedure. Standardized instruments were used to measure parenting style and parent anxiety, whereas a new instrument was developed to measure parent performance of distraction. Children's distress responses were measured with the Observation Scale of Behavioral Distress-Revised (behavioral), salivary cortisol (biological), Oucher Pain Scale (self-report), and parent report of child distress (parent report). Regression methods were used for data analyses.

RESULTS

Variables explaining behavioral, child-report and parent-report measures include child age, typical coping response, and parent expectation of distress (p < .01). Level of parents' distraction coaching explained a significant portion of behavioral, biological, and parent-report distress measures (p < .05). Child impulsivity and special assistance at school also significantly explained child self-report of pain (p < .05). Additional variables explaining cortisol response were child's distress in the morning before clinic, diagnoses of attention deficit hyperactivity disorder or anxiety disorder, and timing of preparation for the clinic visit.

DISCUSSION

The findings can be used to identify children at risk for high distress during procedures. This is the first study to find a relationship between child behavioral distress and level of parent distraction coaching.

Alternatives to intravenous rehydration in dehydrated pediatric patients with difficult venous access

Intravenous (IV) catheter placement in the pediatric patient population can be challenging. Many health care providers automatically choose IV fluid administration to treat dehydration, often not considering other routes. This article reviews the available literature on difficulties in obtaining IV access in the pediatric population and discusses alternative methods for fluid replacement, their respective advantages and disadvantages, and place in therapy.

Impact of Parent-Provided Distraction on Child Responses to an IV Insertion

This study evaluates the impact of parent-provided distraction on children's responses (behavioral, physiological, parent, and self-report) during an IV insertion. Participants were 542 children, 4 to 10 years old, randomized to an experimental group that received a parent distraction coaching intervention or to routine care. Experimental group children had significantly less cortisol responsivity (p = .026). Children that received the highest level of distraction coaching had the lowest distress on behavioral, parent report, and cortisol measures. When parents provide a higher frequency and quality of distraction, children have lower distress responses on most measures.

Pain in children with cerebral palsy: implications for pediatric physical therapy

PURPOSE

This literature review explores pain assessment tools and psychosocial pain management methods that are pertinent to physical therapy (PT) for children with cerebral palsy (CP).

SUMMARY OF KEY POINTS

Children with CP experience considerable pain that affects quality of life and cooperation during healthcare procedures. Physical therapist-led research on interventions to address pain in this population is limited, despite evidence for the prevalence of pain during PT interventions, and the preponderance of research supporting the use of psychosocial pain management during other healthcare-related pain-inducing procedures.

STATEMENT OF CONCLUSIONS AND RECOMMENDATIONS FOR PHYSICAL THERAPY PRACTICE

Research completed primarily by non-physical therapist healthcare professionals delineate assessment tools and psychosocial pain management techniques that hold promise for evaluating and reducing pain that occurs during PT procedures for children with CP.

Pain assessment and management in children with neurologic impairment: a survey of pediatric physical therapists

PURPOSE

This study explored pain assessment measures and interventions used by physical therapists in the treatment of children with neurologic impairment.

METHODS

Following extensive literature review on pain assessment and intervention, a survey was developed, pilot tested, and posted on the listserv of the Pediatric Section of the American Physical Therapy Association.

RESULTS

Eighty percent of the respondents used subjective measures to assess pain, 70% used self-report scales, and 41% used behavioral and physiological measures. Behaviors frequently used included vocalizations, facial expression, and irritability. Rarely used cues included decreased attention, withdrawal, and changes in sleeping and eating behaviors. Therapists used research-supported pain interventions such as distraction and praise as well as potentially harmful distress producing measures such as procedural talk and reassurance.

CONCLUSION

Further research is needed to determine the feasibility of using behavioral pain assessment measures during physical therapy sessions. Physical therapist continuing education regarding nonpharmaceutical pain interventions is indicated.

Do cartoon stickers given after a hemoglobin finger stick influence preschoolers' pain perception?

The purpose of this study was to determine if providing a sticker after a finger stick for hemoglobin check reduced pain perception among preschool-aged children. The hypothesis was: Sticker rewards influence the perception of pain as measured by the Oucher scale following a finger stick to check hemoglobin. Preschoolers from Headstart Centers in a southeastern city were recruited for the study. The age range of participants was between 3 and 5 years. The children were assigned randomly into two groups: those receiving stickers (Group I), and those not receiving a sticker (Group II). Subsequently, each participant's pain level was assessed using the Oucher scale within 1 minute of the finger stick. There was no statistically significant difference in pain scale ratings between the two groups when comparing whether or not a cartoon sticker was given t (-.937, df 128, P = .351; 95% confidence interval). This study was clinically significant in that nonpharmacological interventions were utilized in an attempt to reduce pain in young children. Future research should determine whether receiving rewards (such as a cartoon sticker, adhesive bandages, or small toys) alone or in conjunction with distraction measures are efficacious in pain reduction in younger children.

A systematic review of randomized controlled trials examining psychological interventions for needle-related procedural pain and distress in children and adolescents: an abbreviated cochrane review

OBJECTIVE

To report the results of a systematic review of randomized controlled trials (RCTs) of psychological interventions for children and adolescents undergoing needle-related procedures.

METHODS

A variety of cognitive-behavioral psychological interventions for managing procedural pain and distress in children and adolescents between 2 and 19 years of age were examined. Outcome measures included pain and distress as assessed by self-report, observer report, behavioral/observational measures, and physiological correlates.

RESULTS

Twenty-eight trials met the criteria for inclusion in the review and provided the data necessary for pooling the results. Together, the trials included 1,039 participants in treatment conditions and 951 in control conditions. The largest effect sizes for treatment improvement over control conditions were found for distraction, combined cognitive-behavioral interventions, and hypnosis, with promising but limited evidence for several other psychological interventions.

CONCLUSIONS

Recommendations for conducting future RCTs are provided, and particular attention to the quality of trial design and reporting is highlighted.

Imagery-induced relaxation in children's postoperative pain relief: a randomized pilot study

This study aimed to test the efficacy of imagery and relaxation in hospitalized children's postoperative pain relief. Sixty children aged 8-12 years who had undergone appendectomy or upper/lower limb surgery and had been randomly assigned to the experimental group (n(1) = 30) listened to an imagery trip CD, whereas those in the control group (n(2) = 30) received standard care. An investigator-developed questionnaire was used, and the intensity of pain was assessed using a visual analogue scale: before (Phase 1), immediately after (Phase 2), and 1 hour after (Phase 3) intervention or standard care. The children in the experimental group reported having significantly less pain (p < .001) than the control children based on a comparison of VAS pain scores in Phases 1 and 2. There were no significant differences in nurse-assessed pain scores. The type and time of operation were related to pain intensity in children. The nurses underestimated the pain of pediatric patients. The imagery trip CD can be used to reduce children's postoperative pain in a hospital setting, although its effect is short-lasting.

Parental holding and positioning to decrease IV distress in young children: a randomized controlled trial

Young children are generally restrained in supine position for IV starts, a position that creates fear but is presumed necessary. This study randomly assigned children of ages 9 months to 4 years (N = 118) to being held upright by a parent or lying flat on an exam table for their IV procedure. Distress scores as rated by the Procedure Behavior Rating Scale were significantly lower in the upright positioning group (p = .000); parents were more satisfied with the upright position, and the upright position did not significantly alter the number of IV attempts needed. The upright position appears to be an effective way to decrease IV distress in young children.

Analysis of the validation of existing behavioral pain and distress scales for use in the procedural setting

BACKGROUND

Assessing procedural pain and distress in young children is difficult. A number of behavior-based pain and distress scales exist which can be used in preverbal and early-verbal children, and these are validated in particular settings and to variable degrees.

METHODS

We identified validated preverbal and early-verbal behavioral pain and distress scales and critically analysed the validation and reliability testing of these scales as well as their use in procedural pain and distress research. We analysed in detail six behavioral pain and distress scales: Children's Hospital of Eastern Ontario Pain Scale (CHEOPS), Faces Legs Activity Cry Consolability Pain Scale (FLACC), Toddler Preschooler Postoperative Pain Scale (TPPPS), Preverbal Early Verbal Pediatric Pain Scale (PEPPS), the observer Visual Analog Scale (VASobs) and the Observation Scale of Behavioral Distress (OSBD).

RESULTS

Despite their use in procedural pain studies none of the behavioral pain scales reviewed had been adequately validated in the procedural setting and validation of the single distress scale was limited.

CONCLUSIONS

There is a need to validate behavioral pain and distress scales for procedural use in preverbal or early-verbal children.

A pilot study of distraction for adolescents during allergy testing

PURPOSE

This pilot study describes pain and anxiety associated with allergy testing; tests distraction, specifically self-selected distraction; and examines the relationship between pain, anxiety, and engagement with distraction.

DESIGN AND METHODS

An experimental design was used with a convenience sample of 32 adolescents from an allergist's office randomly assigned to three groups. Pain was measured by the adolescent pediatric pain tool (APPT) and FACES scale.

RESULTS

No differences in pain ratings were found among the groups. Less pain was associated with lower anxiety and greater engagement with distraction. Greater engagement with distraction occurred with less anxiety.

PRACTICE IMPLICATIONS

Knowledge about allergy testing pain, anxiety, and engagement with distraction can assist nurses in preparing adolescents for this procedure.

Needle phobia and stress-reducing medical devices in pediatric and adult chemotherapy patients

Needle phobia--fear of medical devices--is a significant problem in pediatric and adult chemotherapy patients. Stress-reducing medical devices is a new, effective cognitive therapy for needle phobia. Twenty-five pediatric and 25 adult chemotherapy patients were randomly exposed to conventional or stress-reducing decorated butterfly needles and syringes. Emotional stress responses were determined with the Visual Aversion Scale, Visual Analogue Fear Scale, Visual Analogue Anxiety Scale, and Visual Overall Stress Score for each needle and syringe design. Sixty-eight percent of the pediatric and 52% of the adult patients were overtly needle phobic, but children demonstrated significantly more aversion and stress (P < .001). Stress-reducing medical devices effectively and significantly reduced aversion, anxiety, fear, and overall stress, and were 76% effective in preventing overt needle phobia in children and 92% effective in adults (P < .001). One hundred percent of children and adults felt that stress-reducing medical devices should be available in chemotherapy clinics. Needle phobia and stress in pediatric and adult chemotherapy patients are significantly reduced by the use of stress-reducing medical devices.

Psychological interventions for needle-related procedural pain and distress in children and adolescents

BACKGROUND

Needle-related procedures are a common source of pain and distress for children. Several psychological (cognitive-behavioral) interventions to help manage or reduce pain and distress are available; however, a previous comprehensive systematic review of the efficacy of these interventions has not been conducted.

OBJECTIVES

To assess the efficacy of cognitive-behavioral psychological interventions for needle-related procedural pain and distress in children and adolescents.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library (Issue 4, 2005), MEDLINE (1966 to 2005), PsycINFO (1887 to 2005), EMBASE (1974 to 2005), the Cumulative Index to Nursing and Allied Health Literature (1982 to 2005), Web of Science (1980 to 2005), and Dissertation-Abstracts International (1980 to 2005). We also searched citation lists and contacted researchers via various electronic list-servers and via email requests.

SELECTION CRITERIA

Participants included children and adolescents aged two to 19 years undergoing needle-related procedures. Only randomized controlled trials (RCTs) with at least five participants in each study arm comparing a psychological intervention group with a control or comparison group were eligible for inclusion.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed trial quality. Included studies were coded for quality using the Oxford Quality Scale devised by Jadad and colleagues. Standardized mean differences with 95% confidence intervals were computed for all analyses using RevMan 4.0 software.

MAIN RESULTS

Twenty eight trials with 1951 participants were included. Together, these studies included 1039 participants in treatment conditions and 951 in control conditions. The most commonly studied needle-procedures were immunizations and injections. The largest effect sizes for treatment improvement over control conditions exist for distraction (on self-reported pain, SMD -0.24 (95% CI -0.45 to -0.04), combined cognitive-behavioral interventions--reduced other-reported distress (SMD -0.88, 95% CI -1.65 to -0.12; and behavioral measures of distress (SMD -0.67, 95% CI -0.95 to -0.38) with hypnosis being the most promising--self-reported pain (SMD -1.47, 95% CI -2.67 to -0.27), with promising but limited evidence for the efficacy of numerous other psychological interventions, such as information/preparation, nurse coaching plus distraction, parent positioning plus distraction, and distraction plus suggestion.

AUTHORS' CONCLUSIONS

Overall, there is preliminary evidence that a variety of cognitive-behavioral interventions can be used with children and adolescents to successfully manage or reduce pain and distress associated with needle-related procedures. However, many of the included studies received lower quality scores because they failed to describe the randomization procedure and participant withdrawals or drop-outs from the study. Further RCTs need to be conducted, particularly for the many interventions for which we could not locate any trials.
