Psychological interventions for reducing pain and distress during routine childhood immunizations: a systematic review

The role of executive functioning in children's attentional pain control: an experimental analysis

Directing attention away from pain is often used in children's pain treatment programs to control pain. However, empirical evidence concerning its effectiveness is inconclusive. We therefore sought to understand other influencing factors, including executive function and its role in the pain experience. This study investigates the role of executive functioning in the effectiveness of distraction. School children (n=164) completed executive functioning tasks (inhibition, switching, and working memory) and performed a cold-pressor task. One half of the children simultaneously performed a distracting tone-detection task; the other half did not. Results showed that participants in the distraction group were engaged in the distraction task and were reported to pay significantly less attention to pain than controls. Executive functioning influenced distraction task engagement. More specifically, participants with good inhibition and working memory abilities performed the distraction task better; participants with good switching abilities reported having paid more attention to the distraction task. Furthermore, distraction was found to be ineffective in reducing pain intensity and affect. Executive functioning did not influence the effectiveness of distraction. However, a relationship was found between executive functioning and pain affect, indicating that participants with good inhibition and working memory abilities experienced the cold-pressor task as less stressful and unpleasant. Our findings suggest that distraction as a process for managing pain is complex. While it appears that executive function may play a role in adult distraction, in this study it did not direct attention away from pain. It may instead be involved in the overall pain experience.

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.

HEADPLAY Personal Cinema System Facilitates Intravenous Cannulation in Children: A Randomized Controlled Trial

HEADPLAY personal cinema system (PCS) is a portable visual headset/visor through which movie clips may be viewed. We studied the use of HEADPLAY PCS as a distraction tool in facilitating intravenous cannulation in children undergoing anaesthesia. 60 children were enrolled into the study and randomized into 2 groups. EMLA local anaesthetic cream was used to reduce the pain associated with intravenous cannulation. Children in group 1 wore the HEADPLAY visor whereas children in group 2 were subject to conventional distraction therapy. Children were asked to rate their anxiety, pain, and satisfaction scores after intravenous cannulation. Periprocedural anxiety was also determined using the modified Yale Preoperative Anxiety Scale (mYPAS). There were no statistically significant differences in terms of pain and anxiety scores between the 2 groups. Although the satisfaction score of the children in the HEADPLAY PCS group was marginally higher compared to the conventional group, this did not hit statistical significance. 86.6% of children in group 1 reported that they would want to use the visor again for their next intravenous cannulation. We conclude that HEADPLAY PCS is a distraction tool that is acceptable to most children and can contribute towards satisfaction of the intravenous cannulation process in children.

Adult-child interactions in the postanesthesia care unit: behavior matters

BACKGROUND

Many children experience significant distress before and after surgery. Previous studies indicate that healthcare providers' and parents' behaviors may influence children's outcomes. This study examines the influence of adults' behaviors on children's distress and coping in the postanesthesia care unit.

METHODS

Children aged 2-10 yr were videotaped during their postanesthesia care unit stay (n = 146). Adult and child behaviors were coded from video, including the onset, duration, and order of behaviors. Correlations were used to examine relations between behaviors, and time-window sequential statistical analyses were used to examine whether adult behaviors cued or followed children's distress and coping.

RESULTS

Sequential analysis demonstrated that children were significantly less likely to become distressed after an adult used empathy, distraction, or coping/assurance talk than they were at any other time. Conversely, if a child was already distressed, children were significantly more likely to remain distressed if an adult used reassurance or empathy than they were at any other time. Children were more likely to display coping behavior (e.g., distraction, nonprocedural talk) after an adult used this behavior.

CONCLUSIONS

Adults can influence children's distress and coping in the postanesthesia care unit. Empathy, distraction, and assurance talk may be helpful in keeping a child from becoming distressed, and nonprocedural talk and distraction may cue children to cope. Reassurance should be avoided when a child is already distressed.

Effects of distraction on negative behaviors and salivary α-amylase under mildly stressful medical procedures for brief inpatient children

Inconsistent results have been reported on the effects of distraction on negative emotions during medical procedures in infants. These differing results may be attributable to the fact that the effects are apparent under a mildly stressful medical procedure. A total of 17 infants, 18 preschoolers, and 15 school-aged children who were hospitalized were administered, monitoring for vital signs, a mildly stressful medical procedure, by a nurse in a uniform with attractive character designs as a distractor. Consistent with the hypothesis, participating infants showed fewer negative behaviors and lower salivary α-amylase levels when distracted. The results support the efficacy of distraction in infants under a mildly stressful medical procedure.

The effects of mindfulness-based attention on cold pressor pain in children

BACKGROUND

Typical interventions for acute pain in children attempt to reduce pain by directing attention away from pain. Conversely, mindfulness involves devoting attention to one's experience in an accepting and nonjudgmental way. However, the effect that instructing children to mindfully devote attention to acute pain has on pain outcomes is unknown.

OBJECTIVES

To examine whether mindful attention can help children attend to pain without increasing pain intensity or decreasing pain tolerance; to compare the effects of mindful attention with a well-established intervention designed to take attention away from pain (guided imagery); and to test whether baseline coping style or trait mindfulness alter the effects of these interventions.

METHODS

A total of 82 children (10 to 14 years of age) completed measures of coping style and trait mindfulness. Participants then received either mindful attention or guided imagery instructions designed to direct attention toward or away from pain, respectively, before participating in a cold pressor task.

RESULTS

The mindful attention group reported more awareness of the physical sensations of pain and thoughts about those sensations. Overall, there were no between-group differences in measures of pain intensity or pain tolerance during the cold pressor task, and no evidence of an interaction between baseline characteristics of the child and experimental condition.

CONCLUSIONS

Mindful attention was successful in helping children focus attention on experimental pain without increasing pain intensity or decreasing tolerance compared with a well-established intervention for acute pain reduction.

Do cardiorespiratory variables predict the antinociceptive effects of deep and slow breathing?

Deep and slow breathing (DSB) is a central part of behavioral exercises used for acute and chronic pain management. Its mechanisms of action are incompletely understood.

OBJECTIVES

1) To test the effects of breathing frequency on experimental pain perception in a dose dependent fashion. 2) To test the effects of breathing frequency on cardiorespiratory variables hypothesized to mediate DSB analgesia. 3) To determine the potential of the cardiorespiratory variables to mediate antinociceptive DSB effects by regression analysis.

DESIGN

Single-blind, randomized, crossover trial.

SUBJECTS

Twenty healthy participants.

INTERVENTIONS

Visually paced breathing at 0.14 Hz, 0.10 Hz, 0.06 Hz, and resting frequency.

OUTCOME MEASURES

Cardiorespiratory variables: RR-interval (= 60 seconds/heart rate), standard deviation of the RR-interval (SDRR), and respiratory CO2 . Experimental pain measures: heat pain thresholds, cold pain thresholds, pain intensity ratings, and pain unpleasantness ratings.

RESULTS

1) There was no effect of DSB frequency on experimental pain perception. 2) SDRR and respiratory CO2 were significantly modulated by DSB frequency, while RR-interval was not. 3) Baseline-to-DSB and session-to-session differences in RR-interval significantly predicted pain perception within participants: Prolonged RR-intervals predicted lower pain ratings, while shortened RR-intervals predicted higher pain ratings. SDRR and respiratory CO2 were not found to predict pain perception.

CONCLUSIONS

The present study could not confirm hypotheses that the antinociceptive effects of DSB are related to changes in breathing frequency, heart rate variability, or hypoventilation/hyperventilation when applied as a short-term intervention. It could confirm the notion that increased cardiac parasympathetic activity is associated with reduced pain perception.

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.

Pain management strategies used during early childhood immunisation in Victoria

AIM

The study aims to identify pain management practices used during scheduled childhood immunisation.

METHODS

A survey of members of the Australian Nurses Federation (Victorian Branch) Immunisation Nurses Special Interest Group. Questions included frequency of use of pain reduction strategies during immunisations for infants, toddlers and children, injection techniques and existence of an articulated pain management policy.

RESULTS

The survey was emailed to 274 Immunisation Nurses Special Interest Group members with registered email addresses, and 125 (46%) completed the survey. Nineteen respondents (15.2%) stated their main place of employment had a pain management policy during immunisations and 20 (16.0%) respondents were not sure. Distraction strategies were frequently used during immunisation for all age groups, with 95 (76.0%) replying that distraction was used often or always. Breastfeeding during immunisation for infants younger than 6 months was used occasionally (n = 54, 44.6%), often (n = 11, 9.1%) or never (n = 55, 45.5%) and was used even less frequently for infants aged 6-12 months. Sucrose or other sweet solutions were almost never used for infants prior to, or during, immunisation. As a reward, lollies were frequently given to children after immunisations. Topical anaesthetics were almost never used in any age groups. Over half the respondents used a rapid injection technique; 55 (44.7%) used a slow technique and four respondents aspirated the needle before injections.

CONCLUSIONS

Many distraction strategies were used during and following immunisation but sweet solutions, breastfeeding or topical anaesthetics were rarely used. Use of these strategies where feasible, should be facilitated in diverse settings where immunisations take place.

Knowledge translation of the HELPinKIDS clinical practice guideline for managing childhood vaccination pain: usability and knowledge uptake of educational materials directed to new parents

Background

Although numerous evidence-based and feasible interventions are available to treat pain from childhood vaccine injections, evidence indicates that children are not benefitting from this knowledge. Unrelieved vaccination pain puts children at risk for significant long-term harms including the development of needle fears and subsequent health care avoidance behaviours. Parents report that while they want to mitigate vaccination pain in their children, they lack knowledge about how to do so. An evidence-based clinical practice guideline for managing vaccination pain was recently developed in order to address this knowledge-to-care gap. Educational tools (pamphlet and video) for parents were included to facilitate knowledge transfer at the point of care. The objectives of this study were to evaluate usability and effectiveness in terms of knowledge acquisition from the pamphlet and video in parents of newly born infants.

Methods

Mixed methods design. Following heuristic usability evaluation of the pamphlet and video, parents of newborn infants reviewed revised versions of both tools and participated in individual and group interviews and individual knowledge testing. The knowledge test comprised of 10 true/false questions about the effectiveness of various pain management interventions, and was administered at three time points: at baseline, after review of the pamphlet, and after review of the video.

Results

Three overarching themes were identified from the interviews regarding usability of these educational tools: receptivity to learning, accessibility to information, and validity of information. Parents’ performance on the knowledge test improved (p≤0.001) from the baseline phase to after review of the pamphlet, and again from the pamphlet review phase to after review of the video.

Conclusions

Using a robust testing process, we demonstrated usability and conceptual knowledge acquisition from a parent-directed educational pamphlet and video about management of vaccination pain. Future studies are planned to determine the impact of these educational tools when introduced in clinical settings on parent behaviors during infant vaccinations.

Distraction techniques for children undergoing procedures: a critical review of pediatric research

Pediatric patients are often subjected to procedures that can cause pain and anxiety. Although pharmacologic interventions can be used, distraction is a simple and effective technique that directs children's attention away from noxious stimuli. However, there is a multitude of techniques and technologies associated with distraction. Given the range of distraction techniques, the purpose of this article was to provide a critical assessment of the evidence-based literature that can inform clinical practice and future research. Recommendations include greater attention to child preferences and temperament as a means of optimizing outcomes and heightening awareness around child participation in health care decision making.

Oral sucrose for pain control in nonneonate infants during minor painful procedures

PURPOSE

To provide information regarding the effective use of oral sucrose as an analgesic for immunization and venipuncture procedures in the older infant.

DATA SOURCES

Evidence-based literature including original clinical trials, reviews, and clinical practice guidelines.

CONCLUSIONS

Most infants are exposed to multiple minor painful procedures during the first year of life. Oral sucrose solution in a 24% concentration at a dose of 2 mL approximately 2 min prior to the painful procedure has been shown effective in reducing pain during immunizations and venipuncture in the outpatient setting in infants aged 1-12 months old.

IMPLICATIONS FOR PRACTICE

Oral sucrose solution should be used as a pain reduction intervention in infants up to 12 months of age undergoing minor painful procedures. Its proven effectiveness as an analgesic, low rate of minor adverse events, ease of administration, and excellent availability make sucrose a good choice for this purpose. Additional research is needed regarding dose response in different infant age groups, optimal concentration of sucrose solution, need for multiple sucrose dosing, adjustment for multiple painful procedures, and addition of optimal nonpharmacologic interventions as a combination approach.

Practices and perceptions regarding pain and pain management during routine childhood immunizations: Findings from a focus-group study with nurses working at Toronto Public Health, Ontario

INTRODUCTION

Despite the availability of a variety of evidence-based interventions, it has previously been reported that the majority of infants and children undergo vaccine injections without the benefit of analgesia. Nurses in public health administer a substantial number of injections; however, their attitudes and practices surrounding acute pain during vaccine injections have not been previously explored.

METHODS

A focus-group interview was conducted in Toronto, Ontario, with 10 nurses who immunize children. Participants reported their perceptions and practices with regard to vaccine injection pain and pain management.

RESULTS

THREE KEY THEMES EMERGED: environmental and process factors, perceptions regarding the effectiveness of different analgesic interventions, and perceptions regarding pain and fear. Participants reported a lack of control over their environment, resulting in fear and discomfort for children. They recommended increased support from external partners such as school teachers and administrators. Participants reported that pharmacological interventions, such as topical local anesthetics, were not used; however, psychological and physical interventions were commonly used. Nurses questioned the effectiveness of topical anesthetics, and indicated that more education was required regarding effective analgesic interventions. Needle pain was reported to be the most prominent concern for children undergoing vaccine injections, and children were described as being fearful.

DISCUSSION

Nurses reported vaccination setting, analgesic effectiveness and relative importance given to pain as important factors for pain and pain management during vaccine injections. Future studies should explore whether additional perspectives are present in vaccinators in other geographical regions. The effectiveness of educational resources and pain management programs aimed at improving current practices should be investigated.

Is parental anxiety and coping associated with girls' distress during a VCUG? Preliminary findings

PURPOSE

We investigated the relationship between parental anxiety/coping strategies and girls' distress during VCUGs.

METHODS

Parents of 32 girls (age 4-10, mean 5.8 years) completed a trait anxiety measure and a measure of parental reactions to children's distress. Post procedure, children, parents and radiology staff rated the level of anxiety, fear, pain and discomfort.

RESULTS

Trends indicated that parents who reported increased anxiety rated their children as experiencing increased distress (r = 0.27, p = 0.071), similarly for medical staff ratings (r = 0.28, p = 0.061). Parents with lower trait anxiety scores reported using more emotion- and problem-focused coping strategies (r = -0.37 and r = -0.40, p < 0.05, respectively). These were related to children experiencing less procedural distress (r = -0.30, p = 0.054; r = -0.33, p = 0.037, respectively) and parents rated as less anxious by staff (r = -0.40, p = 0.014; r = -0.31, p = 0.047, respectively).

CONCLUSIONS

There was a trend toward parental anxiety being related to their child's distress during VCUG. Parental coping strategies resulted in less distress among children and parents. Teaching coping techniques might obviate the need for sedation and help children deal with future stressors.

Using a tablet computer during pediatric procedures: a case series and review of the "apps"

Children who require procedures and interventions that might be painful or anxiety provoking often require physical restraint, procedural sedation, or both. Nonpharmacologic distraction techniques have been shown to be a helpful adjunct in these situations and can decrease or even eliminate the need for restraint or sedation. We present a case series of children who successfully underwent painful procedures using no restraint or sedation, but rather, distraction with the Apple iPad. We are finding this device to be increasingly useful in the management of pain and anxiety in the pediatric emergency department. We review several available applications (also known as "apps") available on this device with particular attention to features that assist providers in selecting appropriate ones by age, developmental stage, and type of procedure.

Effective analgesia using physical interventions for infant immunizations

BACKGROUND

To measure the analgesic effectiveness of the 5 S's (swaddling, side/stomach position, shushing, swinging, and sucking) alone and combined with sucrose, during routine immunizations at 2 and 4 months.

METHODS

We conducted a prospective, randomized, placebo-controlled trial with 2- and 4-month-old infants during well-child visits. Patients were assigned into 4 groups (2 × 2) receiving either 2 mL of water or 2 mL of 24% oral sucrose and then either standard-of-care comfort measures by parents or intervention with the 5 S's immediately postvaccination. The Modified Riley Pain Score was used to score the infants' pain at 15-second intervals for 2 minutes, then every 30 seconds up to 5 minutes postvaccination. Repeated-measures analysis of variance examined between group differences and within-subject variability of treatment effect on overall pain scores and length of crying.

RESULTS

Two hundred thirty infants were enrolled. Results revealed significantly different mean pain scores between study groups with the exception of the 5S's and 5S's with sucrose groups. These 2 groups had lower similar mean scores over time, followed by sucrose alone, then control. The same trend was found with the proportion of children crying as with the mean pain score outcome measure.

CONCLUSIONS

Physical intervention of the 5 S's (swaddling, side/stomach position, shushing, swinging, and sucking) provided decreased pain scores on a validated pain scale and decreased crying time among 2- and 4-month-old infants during routine vaccinations. The use of 5S's did not differ from 5S's and sucrose.

Epidemiological approaches to measure childhood stress

The prevalence of childhood stress has repeatedly been shown to be high, with 'parental separation' and 'being bullied at school' as the most frequently reported stressors in the child's everyday life. This is quite alarming as children are most vulnerable to the adverse psychological and physiological health consequences of chronic stress exposure. Despite growing research interest in this field over the last years, literature falls short in providing an overview of methods to adequately assess stress in elementary school children (6-12 years old). This review describes questionnaires and interviews, as well as laboratory measurements of cortisol in biological samples (serum, urine, saliva and hair) as stress assessment methods in children, with the emphasis on epidemiological research settings. Major characteristics, strengths and limitations of these methods are established, examples of child-specific stressor questionnaires and interviews are provided and specific recommendations with respect to epidemiological research are formulated. In addition, hair cortisol as a potential biomarker for chronic stress (in children) is discussed more thoroughly. This review is meant to serve as a preliminary guide for health researchers new to this research area by reflecting on theoretical and methodological aspects in childhood stress assessment.

Maternal touch and talk for invasive procedures in infants and toddlers in the pediatric intensive care unit

The aim of this single-blind, randomized, crossover trial was to test the effect of Touch & Talk (T&T) for infants and toddlers less than 36 months of age (N = 65) in the pediatric intensive care unit on their physiological stability and recovery to an invasive procedure. In the T&T condition, mothers touched, sang, or told stories or rhymes to their child during an invasive procedure. In the control condition, the mothers did not have contact with their child. Physiological measures included heart rate, heart rate variability, and oxygen saturation range during the procedure and change from baseline. Time from the end of the procedure until the heart rate returned to baseline levels gave the recovery time. Analysis was conducted using repeated-measures analysis of covariance. There were no significant differences on any of the physiological parameters by condition during the procedure. However, when controlling for severity of illness, recovery was faster with mothers.

The management of procedural pain at the Italian Centers of Pediatric Hematology-Oncology: state-of-the-art and future directions

PURPOSE

The quality of life of children with cancer can be affected by the experience of cancer-related pain, treatment-related pain, procedural pain, generalized pain, and long-term chronic pain, and the consequences may be permanent. Treatment-related pain and procedural pain are often reportedly the most painful experiences relating to their illness. Procedural pain treatment is therefore now considered essential. This multicenter survey investigated how procedural pain is managed at Italian Pediatric Hematology-Oncology Centers.

METHODS

From April to October 2010, questionnaires were collected from the directors and/or referent of the Italian Centers of Pediatric Hematology-Oncology about the management of lumbar punctures, bone marrow aspirates, and biopsies.

RESULTS

We received responses from 67% of the centers (which performed a total of 13,271 procedures per year). Fifty percent of the procedures were performed in the operating room. The sedation-analgesia was provided "almost always" for 84% of procedures. Non-pharmacological treatments were used in 55% of the centers. The specialist who practiced analgesia was the anesthetist in 83.3% of the cases.

CONCLUSIONS

A nationwide multicentre survey has been conducted for the first time to verify the management of procedural pain in Pediatric Hematology-Oncology patients. The results indicate that many aspects in the management of procedural pain appear consistent with the international guidelines. Some problems still remain, including the inability to ensure adequate sedation-analgesia in all the patients--often due to the lack of adequate staff, the frequent use of the operating room, and an underdeveloped use of non-pharmacological therapies.

Sweet tasting solutions for reduction of needle-related procedural pain in children aged one to 16 years

BACKGROUND

Large numbers of studies have shown that oral sucrose or glucose, with or without non-nutritive sucking given prior to painful procedures result in a significant reduction in behavioral pain responses during or following painful procedures compared with placebo, no treatment or non-nutritive sucking alone, in newborns and infants up to 12 months of age. It is not known if these pain-reducing effects exist for older infants and children one year to 16 years of age.

OBJECTIVES

To determine the efficacy of sweet tasting solutions or substances for reducing needle-related procedural pain in children beyond one year of age.

SEARCH STRATEGY

We searched the following databases: the Cochrane Register of Controlled Trials (CCTR), MEDLINE, EMBASE, PsycINFO, ACP Journal Club, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (DARE), Cochrane Methodology Register, Health Technology Assessment, and the NHS Economic Evaluation Database, and on the EBSCOhost interface: CINAHL. We applied no language or document type restrictions. We used the standard methods of The Cochrane Collaboration. The last date of the search was June 30, 2011.

SELECTION CRITERIA

Randomized controlled trials (RCTs) in which children from one year up to 16 years of age, received a sweet tasting solution or substance for needle-related procedural pain. Control conditions included water, non-sweet tasting substances, pacifier, distraction, no treatment, positioning/containment or breastfeeding.

DATA COLLECTION AND ANALYSIS

Outcome measures included composite pain scores, physiological or behavioral pain indicators, self-report of pain or parental- or healthcare professional-report of child's pain. We reported mean differences (MD) with 95% confidence intervals (CI) using fixed-effect or random-effects models as appropriate for continuous outcome measures. We planned to report risk ratio (RR) and risk difference (RD) for dichotomous outcomes. We used the Chi(2) test and I(2) statistic to assess between-study heterogeneity.

MAIN RESULTS

We included four studies (330 participants). Two studies focused on toddlers and pre-school children receiving sucrose for immunization pain compared with water or no treatment and two studies included school-aged children receiving sweet or unsweetened chewing gum before, or, before and during immunization and blood collection. Results for the toddlers/pre-school children were conflicting. Participants in the sucrose group in one study had significantly lower cry duration and behavioral pain scores, compared with the no intervention group, while crying time did not differ between the sucrose and the no intervention group in the other study. For school-aged children, chewing sweet gum either before, or during the procedure, did not significantly reduce pain scores.

AUTHORS' CONCLUSIONS

Based on these four studies, two of which were subgroups of small numbers of eligible toddlers from larger studies, there is insufficient evidence of the analgesic effects of sweet tasting solutions or substances during acute painful procedures in children over one year of age. Further well-conducted RCTs are warranted in this population.

Effect of a clown's presence at botulinum toxin injections in children: a randomized, prospective study

Background

The effect of the presence of a hospital clown during pediatric procedures has rarely been evaluated. In a pediatric ward, botulinum toxin injection is a painful procedure and a stressful experience for the child. We undertook a study of the effect of the presence of a hospital clown on children treated with botulinum toxin in an outpatient setting.

Methods

In total, 60 children, the majority of whom had spastic cerebral palsy, were subjected to a total of 121 botulinum toxin treatment sessions. Thirty-two children were being treated for the first time. During a 2-year period, we enrolled 121 treatment sessions prospectively, and the children were randomized to either the presence of a female clown during treatment or to no presence of a clown. The duration of the child’s crying during the procedure was used as an indicator of the effect of the presence of a clown.

Results

The effect of the clown was significantly related to patient gender. Girls were found to have a significantly shorter period of crying when the clown was present. For children younger than 8 years, the effect on boys was negative. Children treated for the first time did not appear to benefit from the presence of the clown, and showed no difference in effect between genders.

Conclusion

No effect of the clown was documented for children being treated for the first time. At repeat treatments, we saw a positive effect of the female clown in relation to girls, and a negative effect on boys younger than 8 years of age.

Vaccine attitudes, concerns, and information sources reported by parents of young children: results from the 2009 HealthStyles survey

OBJECTIVE

To describe the vaccine-related attitudes, concerns, and information sources of US parents of young children.

METHODS

We calculated weighted proportions and 95% confidence intervals for vaccine-related attitudes, concerns, and information sources of parents with at least 1 child aged 6 years or younger who participated in the 2009 HealthStyles survey.

RESULTS

The overall response rate for the survey was 65% (4556 of 7004); 475 respondents were parents or guardians ("parents") of at least 1 child aged 6 years or younger. Among those respondents, nearly all (93.4%) reported that their youngest child had or would receive all recommended vaccines. The majority of parents reported believing that vaccines were important to children's health (79.8%) and that they were either confident or very confident in vaccine safety (79.0%). The vaccine-related concern listed most often by parents was a child's pain from the shots given in 1 visit (44.2%), followed by a child getting too many vaccines at 1 doctor's visit (34.2%). When asked to list their most important sources of information on vaccines, the most common response was a child's doctor or nurse (81.7%).

CONCLUSIONS

To maintain and improve on the success of childhood vaccines in preventing disease, a holistic approach is needed to address parents' concerns in an ongoing manner. Listening and responding in ways and with resources that address specific questions and concerns could help parents make more informed vaccination decisions.

Educational outreach to reduce immunization pain in office settings

OBJECTIVE

The goal was to examine the impact of a teaching module on immunization pain reduction practices in pediatric offices 1 and 6 months after the intervention.

METHODS

Fourteen practices were selected randomly to receive a 1-hour teaching session on immunization pain reduction techniques, and 13 completed the study. Before the intervention, telephone interviews were conducted with parents concerning their children's recent immunization experiences. At 1 and 6 months after the intervention, parents of children who had recent immunizations were interviewed by using the same questionnaires. Clinicians also were surveyed at baseline and at 6 months.

RESULTS

A total of 839 telephone interviews and 92 clinician surveys were included. Significant changes from baseline were identified at 1 and 6 months after the intervention. At 1 month, parents were more likely to report receiving information (P = .04), using strategies to reduce pain (P < .01), learning something new (P < .01), using a ShotBlocker (P < .01), using sucrose (P < .01), and having higher levels of satisfaction (P = .015). At 6 months, all rates remained significantly higher than baseline findings (all P < .01) except for satisfaction. Clinician surveys revealed significant increases in the use of longer needles, sucrose, pinwheels, focused breathing, and ShotBlockers at 6 months.

CONCLUSIONS

A 1-hour teaching session had measurable effects on the use of pain-reducing strategies at 1 and 6 months after the intervention. This research supports the hypothesis that small-group teaching sessions at the site of care can be associated with changes in practice behaviors.

ABM clinical protocol #23: Non-pharmacologic management of procedure-related pain in the breastfeeding infant

A central goal of The Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient. These guidelines are not intended to be all-inclusive, but to provide a basic framework for physician education regarding breastfeeding.

Inadequate pain management during routine childhood immunizations: the nerve of it

BACKGROUND

Immunization is regarded as one of the most significant medical achievements of all time. Recently, increasing attention has been paid to the pain resulting from routine childhood immunizations.

OBJECTIVE

This narrative review summarizes existing knowledge about: (1) the epidemiology of childhood immunization pain; (2) the pain experience of children undergoing immunization; (3) current analgesic practices; (4) barriers to practicing pain management in children; and (5) recommendations for improvements in pain management during immunization.

METHODS

We conducted a search of MEDLINE, PsycINFO, EMBASE, CINAHL, and the Cochrane Central Register of Controlled Trials for primary research and review articles published from inception of the databases through October 2008. Key search terms included immunization, pain, child/infant, vaccine, and intervention. Additional studies were identified through searches of the reference lists in the retrieved articles. No language restrictions were imposed regarding the type of article (eg, full article, abstract) or language.

RESULTS

Vaccine injections are the most common iatrogenic procedure performed in childhood and a major source of distress for children (of all ages), their parents, and the participating health care professionals, as well as a direct cause of vaccine nonadherence. In addition, lack of adequate pain management during immunization exposes children to unnecessary suffering and the potential for long-term consequences, such as fear of needles. Numerous pain management strategies are available to reduce vaccine injection pain, including: (1) physical interventions and injection techniques; (2) psychological interventions; and (3) phar-macologic and combined interventions. However, adoption of pain-relieving techniques into clinical practice has been suboptimal. The underutilization of pain management strategies can be attributed to a lack of knowledge about pain and effective pain prevention strategies, and the persistence of attitudes about pain that interfere with optimal clinical practices. Current analgesic practices could be improved substantially if all stakeholders involved in immunization (eg, policy makers, practitioners, consumers) participate in efforts to reduce pain. Treating pain during childhood immunization has the potential to reduce distress during the procedure and greatly improve satisfaction with the immunization experience through more positive experiences for children and their families. Other potential benefits include improved adherence to immunization schedules and reduced sequelae of untreated pain.

CONCLUSION

Immunization is a global health priority. Medical care can be improved if pain management becomes a routine aspect of the delivery of vaccine injections.

A systematic review of measures for reducing injection pain during adult immunization

OBJECTIVE

To evaluate the effectiveness of different pain-relieving interventions to reduce pain from immunization in adults.

DATA SOURCES

MEDLINE (1950 to October Week 3 2008) PsycINFO (1967 to December Week 1 2008), CINAHL (1982 to October Week 4 2008), EMBASE (1980 to 2008 Week 43) and the Cochrane Central Register of Controlled Trials (3rd Quarter 2008).

REVIEW METHODS

Databases were searched for trials of pharmacological, behavioural, physical or operator-dependant techniques to reduce pain from immunization in adults. The primary outcome was pain as assessed by visual analogue scale or other numeric rating scale.

RESULTS

Six studies representing 853 participants were identified. One study evaluating pharmacological interventions (lidocaine-prilocaine) found them to be effective in reducing pain from immunization. Similarly, two studies evaluating physical pain relieving techniques, either skin cooling interventions (Fluori-Methane) or tactile stimulation (manual pressure at the site of injection) found them to reduce pain. One study of jet injectors found them to be more painful than conventional needle and syringe. Neither freezing needles nor warming vaccines was found to be effective in reducing pain. No studies investigated psychological interventions or oral analgesics (acetaminophen and ibuprofen).

CONCLUSION

There was limited evidence to support the use of lidocaine-prilocaine, Fluori-Methane and manual pressure for reducing immunization pain in adults. There was limited evidence of more pain with jet injectors compared to needle and syringe. Due to limited data, we recommend further investigation of methods to reduce immunization pain in adults, primarily psychological and physical techniques.
