The effect of medical clowning on reducing pain, crying, and anxiety in children aged 2-10 years old undergoing venous blood drawing--a randomized controlled study

Family participatory clown therapy in venipuncture in hospitalized children: A non-randomized controlled trial

OBJECTIVE

To explore the effectiveness of family participatory clown therapy in venipuncture in hospitalized children.

METHODS

We recruited 104 children aged 3 to 6 years for a non-randomized controlled trial from March to December 2022. All participants required peripheral venepuncture infusions for treatment. The children were assigned to either the control group (n = 52) or the experimental group (n = 52).Standard care was utilized in the control group. In the experimental group, two clown nurses and a parent provided family participatory clown therapy for 35-45 minutes per child before, during, and after venipuncture. We assessed children's pain (FLACC and W-B FPS), anxiety (VAS-A), medical fear (CFS), crying incidence, compliance, parental anxiety (S-AI), and parental satisfaction.

RESULTS

At venipuncture, the FLACC score was lower in the experimental group (4.46±2.053) compared to the control group (5.96±2.441), the W-B FPS score was also lower in the experimental group (4.96±2.392) than in the control group (6.35±2.266), with a statistically significant difference (P<0.05).The children in the experimental group had lower levels of anxiety, medical fear, crying, and parental anxiety than the control group. In addition, child compliance and parent satisfaction were higher in the experimental group than in the control group, with statistically significant differences (P<0.05).

CONCLUSION

Family participatory clown therapy can reduce pain, anxiety, medical fear, and crying during venipuncture in children. It can also improve venipuncture compliance, reduce parental anxiety, and increase parental satisfaction.

Effect of a musical toy used during peripheral venous access on children's pain, fear and parental satisfaction: Randomized controlled trial

PURPOSE

This research was completed to determine the effect of a musical toy (xylophone) on pain and fear in children and parental satisfaction during peripheral venous access in children.

DESIGN AND METHODS

This research was completed as a randomized controlled trial study. The sample for the research comprised 70 children (control: 35, experiment: 35) aged 3-6 years with peripheral venous access who were admitted to the Pediatric ward and their parents abiding with case selection criteria.

RESULTS

The mean Children's Emotional Manifestation Scale score for children in the experiment group was found to be statistically significantly lower than in the control group (p < 0.05). Children in the experiment group had statistically significantly different mean Children's Fear Scale scores, which were found to be low (p < 0.05). No statistically significant difference was found between the pain scores of the experimental and control groups (p > 0.05). There was a statistically significant difference present for patient cooperation with the nurse in the experiment group (p < 0.05).

CONCLUSION

Though the use of a musical toy during the peripheral venous access procedure had positive impacts on fear and emotional symptoms in the child, it did not appear to have any effect on the child's pain level or parental satisfaction.

PRACTICE IMPLICATIONS

The use of a xylophone during painful procedures performed on children is recommended in terms of reducing the negative impact of the procedure on children by ensuring the child and parent focus on each other during the procedure and the parent contributes to care.

Clown care in the clinical nursing of children: a meta-analysis and systematic review

Background

Children treated in hospitals often experience high levels of anxiety and pain. The purpose of this meta-analysis was to analyze the effect of clown care in clinical nursing on children and to provide ideas for improving the clinical nursing care provided to children.

Methods

Two authors searched PubMed, Embase, Clinical trials, Cochrane Library, Web of Science, CINAHL, Scopus, China National Knowledge Infrastructure (CNKI), Weipu, and Wanfang databases to identify randomized controlled trials (RCTs) related to clown care for children until 15 September 2023. The quality assessment of the included RCTs and the data extraction were performed by two researchers, and meta-analysis was carried out using RevMan5.4.

Results

A total of 15 RCTs involving 2,252 children were finally included in this meta-analysis. The findings from this meta-analysis revealed that clown care was beneficial in reducing the pain [SMD = -0.96, 95% CI (-1.76, 0.16)], anxiety [SMD = -0.81, 95% CI (-1.16, -0.46)], and crying time [SMD = -1.09, 95% CI (-1.74, -0.44)] of children and the anxiety level of caregivers [SMD = -0.99, 95% CI (-1.95, -0.03)] (all P's < 0.05). No significant publication biases were detected in the synthesized outcomes (all P's > 0.05).

Conclusions

Clown care is helpful in reducing the pain, anxiety, and crying time of children and the anxiety level of caregivers. However, additional high-quality studies with larger sample sizes are warranted to further analyze the role of clown care in clinical practice.

Medical clowning in hospitals: practices, training and perception

Previous studies on medical clowning focused on patients, while research remains inadequate concerning clowning itself: training programmes and prerequisite requirements, clowning methods, deontology and accepted practices. Diverse approaches and paradigms in this field of complementary medicine are promoted by non-profit organisations worldwide. Based on an ethnographic study, we explore the current forms of medical clowning in 5 Israeli hospitals. The observed clowns are from the two Israeli organisations, Dream Doctors and Simchat Halev (in Hebrew: joy of the heart), consisting of paid professional medical clowns and volunteers, respectively. According to the findings, significant differences were observed to exist between the organisations. Dream Doctors is conceived and pursued as an expertise practised by performance art professionals, requiring extensive training. These clowns work unaccompanied, receive a salary, are considered members of the medical team, and, given their privileged status, have access to hospitals' open and closed areas. The Dream Doctors consider medical clowning as a paramedical practice, in which interventions are individually suited to the circumstances of each patient, and obtain therapeutic results. In contrast, Simchat Halev's medical clowns are volunteers with no prerequisite artistic background and undergo shorter periods of training. The access granted to these clowns, usually working in pairs, is restricted to open areas. Simchat Halev promotes medical clowning as a volunteer-based public practice, offering general entertainment to all patients indiscriminately, and their contribution is characterised as achieving basic entertainment value.

The effect of the distraction methods used before the COVID-19 test on the fear and anxiety levels of children: a RCT study

The current study aimed to investigate the effect of the distraction methods employed before nasopharyngeal swab sampling from children within the scope of the COVID test on their anxiety and fear levels. The study was an RCT with parallel groups conducted according to the CONSORT statement at the pediatric emergency unit of a hospital in Turkey. Children aged 5-10 years were randomized into three groups: Kaleidoscope, Visual Illusion Cards, and control. Data were collected by the researchers using the Descriptive Characteristics Form, the Children's Anxiety Meter-State, and the Children's Fear Scale. According to the reports of the children, the parents, and the nurse, the mean anxiety score and the mean fear score in the experimental groups were significantly lower after the nasopharyngeal swab procedure compared to the control group (p < .05). Fear and anxiety were observed less in the visual illusion cards group and the kaleidoscope group.

Benefits to Clinicians of Nonpharmacological Distraction During Pediatric Medical Procedure

CONTEXT

Nonpharmacologic distraction (NPD) during medical procedures in children is known to be beneficial to patients; however, no reviews have assessed their benefits to medical providers.

OBJECTIVES

We aimed to assess the benefits of NPD to medical providers.

DATA SOURCES

We searched 5 databases for relevant articles.

STUDY SELECTION

Peer-reviewed published randomized controlled trials comparing NPD with standard care that included children who had undergone medical procedures were included.

DATA EXTRACTION

Primary outcomes were procedure time, number of medical staff involved, and initial success rate of venipuncture. Two reviewers assessed the risk of bias by using the Cochrane Collaboration (Oxford, United Kingdom)'s Randomized Controlled Trials Risk of Bias Tool, and we performed a meta-analysis to assess efficacy.

RESULTS

We included 22 trials with 1968 participants. The main NPD was audiovisual distraction, such as tablets. No significant difference was found in venipuncture procedure time (mean difference: -9.79; 95% confidence interval: -22.38 to 2.81; low certainty). We found no studies on the number of medical staff.

CONCLUSIONS

Our review did not find any clear NPD-associated benefit for the medical provider. The review included a small amount of literature, analyzed a small number of cases, and had a low certainty of evidence regarding procedure duration; therefore, further studies are needed to conclude the benefits to clinicians of NPD.

Medical clowns improve sleep and shorten hospitalization duration in hospitalized children

Intervention by medical clowns was proven to have a positive effect in reducing stress and anxiety, increasing cooperation and improving the child's experience prior to a medical procedure and during the various stages of hospitalization. Sleep has long been known to be essential for recovery from injury and sickness, improving immune functions, and there is an emerging understanding of the restorative role quality sleep has on health and diseases. Hospitalized children are more exposed to sleep disorders and sleep deprivation due to the hospitalized environment, anxiety, and illness. Different behavioral interventions to promote sleep were previously studied in hospitalized children, some showing potential benefits. In this study, we sought to examine the ability of medical clowns to positively impact the child's sleep during hospitalization. The study is an observational matching (case-control) interventional study which took place at the department of pediatrics in Carmel Medical Center. Forty-two hospitalized children ages 2-17 were included in two equal groups of intervention or control. Children in the control group were recruited based on a method of matching the chief complaint plus the medical diagnosis and age of the children in the intervention group in a 1:1 matching. The children's sleep parameters were objectively evaluated for two consecutive nights using an Actigraph device and subjectively by parent's questionnaire. Additional factors such as hospital length of stay and demographics were also monitored. The study group had an encounter with a medical clown (15-30 min) before bedtime on either the first or the second night, and the control group was not exposed to a medical clown at all. We then compared the data from both groups using unpaired t-tests. Hospitalized children exposed to a medical clown prior to bedtime (n = 21) and children not exposed to a medical clown (n = 21) were comparable in age and clinical characteristics. The study group had a significantly delayed wake-up time compared to the control group (06:59 ± 46 min vs. 07:26 ± 42 min, p < 0.05) (mean difference of 27 min). Night's duration (from bedtime to wake-up) was significantly longer in the study versus the control group (570 ± 76 vs. 500 ± 66.1 min, p < 0.05), a total mean increase of 70 min, and sleep efficiency were significantly increased (92.3 ± 4.6% vs. 87.9 ± 8.7%, p < 0.05). Within the clown group, when comparing nights with and without exposure to a medical clown, total sleep time was prolonged by a mean of 54 min on the night of the intervention (518 ± 74 min vs. 464 ± 59 min, p < 0.01), and the total wake time during the night were reduced (52 ± 27 min vs. 77 ± 61 min, P < 0.05), mean difference of 25 min), mainly by reduction of wake period after sleep onset (WASO) (42 ± 25 min vs. 66 ± 58 min, p < 0.05), mean difference of 24 min). Regarding general medical outcomes, hospital stay was significantly shorter in the clown group vs. control (104 ± 42 h vs. 128 ± 42 h, p < 0.05), a mean reduction of 23 h-nearly an entire day. An encounter with a medical clown before bedtime in hospitalized children positively affects sleep parameters, which may be of great importance for healing in general. The clown intervention was also shown to shorten the hospital stay. Larger scale studies are warranted to establish these findings.

Medical clowning in hospitalized children: a meta-analysis

BACKGROUND

Medical clowning has been proven effective in reducing pain, anxiety, and stress in many sporadic, usually small-scale studies. Our meta-analysis aims to evaluate the efficiency of medical clowns in reducing pain and anxiety in hospitalized pediatric patients and their parents in different medical fields.

METHODS

A thorough literature search was conducted from different databases, and only randomized controlled trials (RCTs) were included with children aged 0 to 18 years old. A total of 18 studies were included, and statistical analysis was performed on the combined data.

RESULTS

A total of 912 children (14 studies) showed significantly reduced anxiety when procedures were performed with a medical clown compared with the controls (- 0.76 on anxiety score, P < 0.001). Preoperative anxiety was lower in 512 children (nine studies) with clown interventions than in the controls (- 0.78, P < 0.001). The pain scale was completed by 338 participants (six studies), indicating a trend toward reduced pain during procedures performed while the clown was acting compared to controls (- 0.49, P = 0.06). In addition, medical clown significantly (- 0.52, P = 0.001) reduced parental anxiety in 489 participants in ten studies; in six of the ten studies, with a total of 380 participants, medical clown significantly reduced parental preoperative anxiety (P = 0.02).

CONCLUSION

Medical clowns have substantial positive and beneficial effects on reducing stress and anxiety in children and their families in various circumstances in pediatrics.

Why Laughing Heals? A Review on the Use of Humor in Therapy

Humor is an important tool for expressing many emotions such as happiness, sadness, anger and surprise. In recent years, the use of humor has started to gain the quality of a therapy approach. The use of humor in therapy helps clients to express meaningless situations or inconsistencies in their lives in a humorous way by making them entertaining. At this point, it is very important for the counselor to be able to understand the purpose of the clients' arrival and their sense of humor depending on this purpose and to make interventions accordingly. Since the concepts of humor therapy and Laughter Therapy / Laughter Yoga are often used interchangeably in the literature, this study synthesizes both therapy approaches and tries to reveal their elements and importance. In this review, it is aimed to examine all aspects of the emergence of the use of humor in therapy, basic concepts, sub-dimensions of humor, counselor-client relationship using humor in therapy, humor therapy process, laughter therapy / laughter yoga process, laughter therapy / laughter yoga techniques, studies on the use of humor in therapy, why humor should or should not be used in therapy. In these respects, this study is expected to contribute to the literature and help fill the existing gaps. In addition, it is predicted that the widespread use of humor therapy and the use of humor therapy in different studies will benefit many clients and experts working in this field.

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.

The effect of medical/therapeutic clowns on the playfulness of children with intellectual disabilities

BACKGROUND

Play is an essential component of children's development. Children with intellectual disability tend to have poor socioemotional abilities and impaired play. This study examined the effects of a medical/therapeutic clowning play intervention on the playfulness of children with intellectual disability.

METHOD

Two medical clowns facilitated a play intervention in a preschool classroom setting with a total of 52 children with intellectual disability. We compared before and after two groups that received the intervention: group 1 met the medical clowns once a week for 6 months (long-intervention group) and group 2 for 3 months (short intervention group). Children's functioning was assessed using the Vineland Adaptive Behaviour Scales. Children's playfulness was scored using the Test of Playfulness observational assessment. A teachers' focus- group was used to gather additional information on the clowns' work.

RESULTS

Children's playfulness increased significantly at the end of the intervention, whereas the improvement in the playfulness scores of group 1 was significantly larger than those of group 2 (t₅₀  = -4.82, p < .001). The teachers' focus group revealed additional benefits of the medical clowns' work.

CONCLUSION

The results shed light on the play and playfulness of children with intellectual disability and the possible contribution of a clowning play intervention to their development.

The beneficial effect of medical clowns on performance of EEG in young children: a randomized controlled study

Electroencephalography (EEG) is an important test in the diagnosis of epilepsy. To perform the test, many electrodes are placed on the child's scalp, a stressful situation that may contribute to uncooperative behavior. The aim of our study was to investigate the effects provided by a close collaboration with medical clowns on the performance of EEG in young children. A prospective randomized control study was conducted between July 2020 and September 2021. The study included children aged 1-5 years who were scheduled to undergo EEG testing at the Bnai Zion Medical Center. The children were randomly allocated to each group (study group with medical clowns and control group without medical clowns) according to the day of the test. The medical clowns, the EEG technician, and the children's caregivers all independently rated the entire process in designated questionnaires composed of items rated on a 5-point Likert scale. In addition, the technical quality of all EEG tests was evaluated and rated by one neurologist (G.J.) in a blinded manner. One hundred children participated in the study. Fifty children underwent the EEG accompanied by one of two medical clowns (study group), and fifty children underwent routine EEG, without medical clowns (control group). The physician-rated technical score of the EEG recording was significantly higher in the study group (p < 0.001). Among parents of the study group, 96% were highly satisfied from the presence of the medical clowns during the EEG (median 5). Both the EEG technician and the parents denoted a significantly higher cooperation rate in the study group children, of 72% and 82%, respectively, compared to the control group. The rating of child/parent's cooperation was not correlated with age, sex, or ethnicity of the child. There was no need for sedation in the study group.

CONCLUSION

Performing EEG in young children in collaboration with medical clowns can increase the quality of the EEG recording possibly due to higher cooperation rates, which in turn lead to mutual satisfaction of both parents and technicians with the procedure.

TRIAL REGISTRATION

NCT05257096.

WHAT IS KNOWN

• Performing EEG in young children may be a stressful experience. • Use of sedation during EEG may cause side effects. To avoid need for sedation various methods are used to overcome the stressful experience: Natural daytime nap, partial sleep deprivation, oral melatonine and reassurance of parents.

WHAT IS NEW

• Performing EEG in young children in collaboration with medical clowns can increase the quality of the EEG recording. • Medical clown intervention led to mutual satisfaction of both parents and technicians with the EEG test procedure.

Motivations and Personal Traits Can Predict Self-Efficacy of the Clown Therapist: A Descriptive Study

The individual and collective perception of self-efficacy in clown therapists is fundamental in order to be able to be active, restrained, energetic and defocused, if necessary, without being overwhelmed by any problems patients might have. The present study evaluated both the incidence of motivational and dispositional functions on the level of perceived self-efficacy with a sample of 259 Italian clown therapists who were administered The Volunteer Self-Efficacy Scale, the Volunteer Process Model and the Italy Personality Inventory. The significance of a hierarchical linear regression model of perceived self-efficacy was tested. The results showed that the value orientation of the operators mainly influenced the level of perceived self-efficacy, that is, the search for actions with a high social meaning, rather than the orientation towards situations and experiences that allow one to expand one's knowledge and promote one's own person. Profiles with higher perceived self-efficacy were associated with the trait of dynamism and conscientiousness, while a person's vulnerability was found to be a significant negative predictor of self-efficacy. An additional significant predictor was the experience of the clown therapist. The results of the study also showed a positive and functional role of the synergy conferred by teamwork. The group mitigates the emotional difficulties of the individual and supports him/her by orienting him/her technically and compensating for any inexperience in the field of animation in sensitive contexts, such as hospital wards with serious and vulnerable patients, such as children.

Clown therapy for procedural pain in children: a systematic review and meta-analysis

Among the distraction techniques used for the non-pharmacological management of acute pediatric pain, one of the most performed is clown therapy. Despite the presence in the literature of some systematic reviews that evaluate its effectiveness, none of them examines its outcomes on procedural pain which has therefore been investigated in this study. The literature search for randomized controlled trials (RCTs) was performed on the Cochrane Library, MEDLINE, EMBASE, CINAHL, PsycINFO, Web of Science, and Scopus over a time frame ranging from each database setup date to 31 July 2021. The primary outcome was the procedural pain of children. We used the Cochrane Risk of Bias tool to assess the risk of bias of the included studies. Six RCTs were selected for this review, which included a total of 517 pediatric subjects. Children undergoing clown therapy during the venipuncture or peripheral vein cannulation procedure reported less pain than those exposed to the standard of care (SMD =  -0.55; 95% CI: -1.23, 0.13) but the result was not found to be statistically significant. School-aged children and adolescent reported significantly less pain (SMD =  -0.51; 95% CI: -0.92, -0.09). Compared to the standard of care, children's anxiety was significantly lower with clown therapy (SMD =  -0.97; 95% CI: -1.38, -0.56).

CONCLUSION

Clown therapy seems effective in reducing procedural pain in children, particularly for older age groups, but due to poor methodological quality and the high risk of bias of the studies included, the results obtained should be considered with caution.

WHAT IS KNOWN

• Clown therapy is one of the most used techniques in the non-pharmacological management of acute pediatric pain. • Laughter physiologically stimulates the production of beta-endorphins, substances with an effect similar to opiates.

WHAT IS NEW

• Clown therapy seems effective in reducing procedural pain and anxiety in children. • The intervention in school-age children or adolescents produces a statistically significant decrease in the symptom.

Relieving pain and distress symptoms in the outpatient burn clinic: The contribution of a medical clown

CONTEXT

High levels of pain and emotional distress characterize the experience of patients, at burn outpatient clinic and reflect on their accompanying persons and the medical personal.

OBJECTIVES

To examine the effect of a medical clown presence on: the patients' pain and distress levels as perceived by the patient and by their accompanying persons, and the emotional response of healthcare personnel.

METHODS

A yearlong prospective observational comparative study in the burn outpatient clinic, operating twice a week, with a medical clown's presence once a week [Exposure Group - EG] versus clinic without clown presence [Non exposure Group- NEG]. Patients and accompanying persons filled pain [WBS, VAS] and emotional distress [SUDS] questionnaires regarding the patient's experience: before (T1) and after treatment (T2). The clinic personnel filled SUDS at the beginning and the end of the clinic working hours.

RESULTS

Significantly lower WBS, VAS, and SUDS scores were reported at T2 in the EG as compared to the NEG both in patients and in the accompanying persons' evaluations. Personnel SUDS were affected in a similar manner.

CONCLUSION

Presence of a medical clown induced a positive atmosphere in the clinic. It is possible that the effect of humor through stress reduction mechanism lessened agony. Furthermore, the distraction the clown evoked played a role in the decrease of pain and emotional distress. We recommend implementing psychosocial oriented interventions such as those performed by a medical clown to improve the emotional atmosphere in the ambulatory clinic of patients, accompanying persons and healthcare personnel.

Managing acute pain in children presenting to the emergency department without opioids

Pediatric pain is challenging to assess and manage. Frequently underestimated in children, untreated pain may have consequences including increased fear, anxiety, and psychological issues. With the current opioid crisis, emergency physicians must be knowledgeable in both pharmacologic and non‐pharmacologic approaches to address pain and anxiety in children that lead to enhanced patient cooperation and family satisfaction. This document focuses pain management and distress mitigation strategies for the brief diagnostic and therapeutic procedures commonly performed.

Effectiveness of clown intervention for pain relief in children: A systematic review and meta-analysis

BACKGROUND

Pain is common in children receiving medical procedures, and there is a lack of adequate awareness and management. In addition, children who undergo medical procedures involving pain may also experience stress, crying and prolonged hospitalisation. Clown intervention is a promising nonpharmacological intervention. However, studies on the effectiveness of clown intervention in pain management have reported conflicting findings.

OBJECTIVE

To evaluate the effectiveness of clown intervention in relieving pain in children, as well as its effects on cortisol levels, crying duration and length of hospital stay.

DESIGN

Systematic review and meta-analysis of randomised controlled studies.

DATA SOURCES

PubMed, Web of Science (SCI), Embase, PsycINFO, the Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), Weipu (VIP), Wanfang Data and SinoMed were systematically searched from inception date to December 31, 2020.

REVIEW METHODS

Two reviewers independently used the Cochrane risk of bias tool to assess the risk of bias of the included studies. Meta-analysis was conducted when data were available, otherwise, a narrative description was provided. Data were analysed using Review Manager 5.3. The review process is reported according to PRISMA.

RESULTS

Nine studies including 852 children met the inclusion criteria. The results showed that compared with standard care, clown intervention was beneficial for relieving pain. Further subgroup analysis showed that it was more effective with children aged 2-7 years. The duration of crying after the procedure and the length of stay were shortened, but there was no significant difference in cortisol levels.

CONCLUSION

Clown intervention may be a promising way to relieve acute pain in children, especially those aged 2-7 years. It also seems to shorten the duration of crying and the length of hospital stays, but the effect on cortisol levels is still uncertain. More high-quality randomised controlled trials are needed to confirm these results and take into account different age groups, cultural backgrounds and specific populations.

Smartphone Interventions Effect in Pediatric Subjects on the Day of Surgery: A Meta-Analysis

Background: A meta-analysis was performed to evaluate the effect of smartphone interventions on the anxiety of the pediatric subjects at induction on the day of surgery compared to oral midazolam or standard care as control. Methods: A systematic literature search up to June 2021 was performed and nine studies selected 785 pediatric subjects on the day of surgery at the start of the study; 390 of them were using smartphone interventions, 192 were control, and 203 were using oral midazolam. They were reporting relationships between the effects of smartphone interventions on the anxiety of the pediatric subjects at induction on the day of surgery compared to oral midazolam or control. The mean difference (MD) with its 95% CIs was calculated to assess the effect of smartphone interventions on the anxiety of the pediatric subjects at induction on the day of surgery compared to oral midazolam or control using the continuous method with a fixed or a random-effects model. Results: Smartphone interventions in pediatric subjects were significantly related to lower anxiety at induction on the day of surgery (MD, -19.74; 95% CI, -29.87 to -9.61, p < 0.001) compared to control and significantly related to lower anxiety at induction on the day of surgery (MD, -7.81; 95% CI, -14.49 to -1.14, p = 0.02) compared to oral midazolam. Conclusion: Smartphone interventions in pediatric subjects on the day of surgery may have lower anxiety at induction compared to control and oral midazolam. Further studies are needed to confirm these findings.

The Effect of Music-Moving Toys to Reduce Fear and Anxiety in Preschool Children Undergoing Intravenous Insertion in a Pediatric Emergency Department: A Randomized Clinical Trial

INTRODUCTION

Intravenous catheter insertion is a highly invasive medical procedure that causes fear and anxiety in children. This study aimed to analyze the effect of a toy (with music and movement) distraction method on fear and anxiety in children aged 4 to 6 years.

METHODS

This experimental, randomized clinical trial used parallel trial design guided by the Consolidated Standards of Reporting Trials checklist. Using simple randomization, eligible children (age 4-6; N = 60) were assigned to the intervention group (n = 30), who received the toy distraction method, or to the control group (n = 30), who received standard care. The Children's Fear Scale was used to evaluate the fear levels, and Children's State Anxiety Scale was used to evaluate anxiety levels. Physiological parameters (pulse, oxygen saturation) and crying time were monitored by the researcher as indicators of fear and anxiety. The chi-square test, repeated measures analysis of variance, Friedman test, t test, the Mann-Whitney U test, Wilcoxon test, and the intraclass correlation test were used for data analysis.

RESULTS

There was no statistically significant difference in terms of fear and anxiety scores, physiological parameters, and crying time during the procedure between the children in the intervention and control group.

DISCUSSION

We found that this method of toy distraction was not effective in reducing fear or anxiety during the intravenous catheter insertion procedure. Accordingly, we recommend that this distraction method be performed in different age groups and with larger samples in various painful and stressful practices in the future and that comparison be made with various distraction methods.

Medical Clowning: A Cost-Effective Way to Reduce Stress Among Children Undergoing Invasive Procedures

Background

Distraction techniques like medical clowning and the use of soap bubbles can aid in reducing children’s stress levels while undergoing invasive medical procedures. Such complementary therapies are not a common practice in Pakistan, and data exploring the potential benefits of complementary therapies are sparse. This study aimed to determine whether distractions like medical clowns and soap bubbles could reduce anxiety and pain perceived by children undergoing invasive medical procedures in a hospital in Pakistan.

Material and methods

We conducted a randomized controlled trial of 76 pediatric patients (aged six to 12 years) whose treatment required a peripheral intravenous (IV) catheter insertion at the pediatric ward of the Fauji Foundation Hospital in Rawalpindi, Pakistan, from March 2016 to June 2016. Peripheral IV catheter insertion was required for all patients as part of their treatments (no participants received IV catheter placement solely for this study). Our sample size was selected via random sampling, and we excluded patients whose parents or legal guardians did not consent for their inclusion. Study participants were randomly assigned to either a clown group (n=38) or a control group (n=38). The patients in the clown group underwent IV catheter placement while interacting with the medical student clown and soap bubbles in the presence of a parent. Patients in the control group underwent IV catheter placement with support provided only by the parent. We assessed the patient’s distress and anxiety before, during, and after the procedure. We used the Observation Scale of Behavioral Distress (OSBD), before and after the procedure with the short version of self-reported Spielberger’s State-Trait Anxiety Inventory-Children (STAI-C), the visual analog anxiety scale (VAS), and pain experienced with the Wong-Baker Faces pain scale (FPS) only after the procedure. Additionally, we collected demographic information. The hospital's ethical review committee approved our study design.

Results

Of the 76 study participants, 53.9% were male and 46.1% were female. Most patients lived in a rural setting (67%). Mean values of the FPS, OSBD, and STAI-C for the clown group (3.21, 6.23, and 8.52, respectively) were all lower than those for the control group (8.00, 18.02, and 15.29, respectively; p<.001); however, the difference was not statistically significant for children older than 10 years. After IV catheter placement, the mean VAS score for the clown group was also significantly lower than that for the control group (2.84 vs. 8.92, respectively; p<.001).

Conclusion

The use of distractions via medical clowns and soap bubbles was an effective nonpharmacological method of reducing anxiety and perceived pain in children undergoing invasive medical procedures. Therefore, proceduralists could use such techniques as powerful, noninvasive, and cost-effective complementary and alternative medicine tools in pediatric treatment settings in Pakistan. Further studies on the potential benefits of the aforementioned techniques are warranted.

The effectiveness of a medical clowning program on improving emotional status among hospitalized children undergoing cancer treatment: A quasi-experimental study

PURPOSE

To examine the effectiveness of one-time medical clowning on improving short-term positive emotions among hospitalized children undergoing cancer treatment, and to analyze whether age moderates this effect.

DESIGN

In this quasi-experimental research study, we recruited a pooled sample of 96 children who were undergoing cancer treatment in pediatric oncology/hematology wards at three university-affiliated medical centers in Taiwan from June 2018 through April 2020.

METHODS

Children's demographic characteristics, symptom distress, quality of life, and pretest emotional status were collected at T1. At T2, we collected only posttest emotional status. We adapted generalized estimating equation models to evaluate the effectiveness of medical clowning on enhancing positive emotions.

FINDINGS

Changes in the probabilities of positive emotion were significantly different across groups (51.84% for the experimental group, 15.76% for the control group; Δ = 36.08, p = 0.001), and the change was more than two times larger for the experimental group (effect ratio = 3.28, p < 0.05) than for the control group. When evaluating the moderating effect of age on the intervention, none of the coefficients reached the significant (p < 0.05) levels, suggesting that age may not moderate the intervention effect.

CONCLUSION

This study demonstrates the core value of medical clowning in child-friendly health care. Our findings clearly support the benefit of the one-time medical clowning program on enhancing short-term emotional well-being across age groups of children. Medical clowning programs should be strongly encouraged and supported in pediatric oncology wards.

CLINICAL RELEVANCE

Medical clowning programs should be widely and continuously implemented in pediatric oncology wards as a routine clinical practice for enhancing emotional well-being among children receiving cancer treatment. Nurses need to be aware of medical clowning's equal effectiveness across age groups, not only or better for younger children.

Effects of therapeutic clowning on pain and anxiety during venous blood sampling in Turkey: Randomised controlled trial

PURPOSE

The research aim was to investigate the effects of therapeutic clowning on pain and fear during the process of venous blood sampling in children.

DESIGN AND METHODS

This study was conducted in a randomised controlled trial from January to March 2020. The study population consisted of children from 7 to 12 years of age who came to the research centre for blood sampling. The research sample consisted of 166 children (83 in the intervention group and 83 in the control group) who met the research criteria and came to the research centre on a specific date through probable sampling. For the data collection, a questionnaire form, the Visual Analogue Scale and the Children's Fear Scale were used. Therapeutic clowning was used in this process for the intervention group. There was no intervention for children who were in the control group. The calculation of percentage distribution and means, χ² test, analysis of variance analysis in repeated measures and least significant difference and independent t-test were used to analyse the data.

RESULTS

The results of the research indicated that children in the intervention group had significantly lower pain and fear than children in the control group (p < .001). Therapeutic clowning seems to effectively reduce pain and fear during venous blood sampling for children from 7 to 12 years of age. Our results support using therapeutic clowns which is an inexpensive, safe, and effective method for lowering children's pain and fear during venous blood sampling.

PRACTICE IMPLICATIONS

The use of therapeutic clowns could become the standard of care in blood sampling for children from 7 to 12 years of age in hospitals. Therapeutic clowning, which is an easy-to-use, low-cost and practical method to provide better communication and cooperation with the family and the child, can be used as a complementary therapy in all nursing areas, especially in the field of paediatrics. Nurses could be encouraged to be trained on the use of therapeutic humour based upon a standardised approach and offered guidance on how to apply entertaining methods such as clowns. Therapeutic clowning can be examined in other applications in nursing care in light of these results.

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.

The Effect of Cartoon Watching and Distraction Card on Physiologic Parameters and Fear Levels During Inhalation Therapy in Children: A Randomized Controlled Study

OBJECTIVE

The study was conducted as a randomized controlled study to investigate the effect of cartoon watching and distraction cards on physiologic parameters and fear levels in children with acute bronchitis in the emergency department.

METHODS

Ninety-nine children with acute bronchitis aged 3-6 years were randomized in the emergency department. The study was conducted with three groups: cartoon group, distraction card group, and the control group. Data were collected using a follow-up form and the Children's Fear Scale.

RESULTS

The difference between the mean pulse rates of the groups evaluated by an observer nurse was found to be statistically significant. The pulse rates of the cartoon and distraction card groups were lower than in the control group during inhalation therapy (p < 0.05). The difference between the mean fear scores in the cartoon and control groups as evaluated by the observer nurse and the accompanying parent was found to be statistically significant during after inhalation therapy (p < 0.01).

CONCLUSION

It was observed that watching cartoons during inhalation therapy was more effective in reducing the level of fear in children that distraction card.

Exploring the usefulness of medical clowns in elevating satisfaction and reducing aggressive tendencies in pediatric and adult hospital wards

BACKGROUND

Most existing research on medical clowns in health care services has investigated their usefulness mainly among child health consumers. In this research we examined multiple viewpoints of medical staff, clowns, and health consumers aiming to identify the optimal audience (adult or child health consumers) for which medical clowns are most useful. We focused on exploring their usefulness in enhancing health consumers' satisfaction and, in turn, reducing their aggressive tendencies.

METHODS

We conducted three studies that examined the placement fit of medical clowns from different points of view: medical staff (Study 1, n = 88), medical clowns (Study 2, n = 20), and health consumers (Study 3, n = 397). The main analyses in Studies 1 and 2 included frequencies and t-tests comparing perceived adult and child satisfaction with clowns' performance. Study 3 used moderated-mediation PROCESS bootstrapping regression analysis to test the indirect effect of negative affectivity on aggressive tendencies via satisfaction. Exposure to the medical clown moderated this relationship differently for different ages.

RESULTS

Studies 1 and 2 show that the majority of medical clowns and medical staff report that the current placement of the medical clowns is in pediatric wards; about half (44% of medical staff, 54% of medical clowns) thought that this placement policy should change. In Study 3, data from health consumers in seven different hospital wards showed that clowns are useful in mitigating the effect of negative affectivity on satisfaction, thereby reducing aggressive tendencies among health consumers under the age of 21.6 years. Surprisingly, medical clowns had the opposite effect on most adults: for health consumers who were exposed to the medical clown and were above the age of 21.6 negative affectivity was related to decreased satisfaction, and an increase in aggressive tendencies was observed.

DISCUSSION

Medical clowns are most useful in elevating satisfaction and reducing aggressive tendencies of children. Older adults, on the other hand, exhibit lower satisfaction and higher aggressive tendencies following exposure to the performance of medical clowns.

CONCLUSION

Medical clowns should be placed primarily in children's wards.

Effectiveness of hospital clowns for symptom management in paediatrics: systematic review of randomised and non-randomised controlled trials

OBJECTIVE

To evaluate evidence from randomised controlled trials and non-randomised controlled trials on the effectiveness of hospital clowns for a range of symptom clusters in children and adolescents admitted to hospital with acute and chronic conditions.

DESIGN

Systematic review of randomised and non-randomised controlled trials.

DATA SOURCES

Medline, ISI of Knowledge, Cochrane Central Register of Controlled Trials, Science Direct, Scopus, American Psychological Association PsycINFO, Cumulative Index to Nursing and Allied Health Literature, and Latin American and Caribbean Health Sciences Literature.

STUDY SELECTION

Randomised and non-randomised controlled trials were peer reviewed using the following eligibility criteria: children and adolescents who were admitted to hospital for acute conditions or chronic disorders, studies comparing use of hospital clowns with standard care, and studies evaluating the effect of hospital clowns on symptom management of inpatient children and adolescents as a primary outcome.

DATA EXTRACTION AND SYNTHESIS

Two investigators independently screened studies, extracted data, and appraised the risk of bias. Methodological appraisal was assessed by two investigators independently using the Jadad scale, the revised Cochrane risk-of-bias tool for randomised controlled trials (RoB 2), and the risk of bias in non-randomised studies (ROBINS-I) tool for non-randomised controlled trials.

RESULTS

24 studies (n=1612) met the inclusion criteria for data extraction and analysis. Most studies were randomised controlled trials (n=13). Anxiety was the most frequently analysed symptom (n=13), followed by pain (n=9), psychological and emotional responses and perceived wellbeing (n=4), stress (n=4), cancer related fatigue (n=3), and crying (n=2). Five studies used biomarkers, mainly cortisol, to assess stress or fatigue outcome following hospital clowns. Most of the randomised controlled trials (n=11; 85%) were rated as showing some concerns, and two trials were rated with a high risk of bias. Most non-randomised controlled trials (n=6; 55%) were rated with a moderate risk of bias according to ROBINS-I tool. Studies showed that children and adolescents who were in the presence of hospital clowns, either with or without a parent present, reported significantly less anxiety during a range of medical procedures, as well as improved psychological adjustment (P<0.05). Three studies that evaluated chronic conditions showed favourable results for the intervention of hospital clowns with significant reduction in stress, fatigue, pain, and distress (P<0.05).

CONCLUSIONS

These findings suggest that the presence of hospital clowns during medical procedures, induction of anaesthesia in the preoperative room, and as part of routine care for chronic conditions might be a beneficial strategy to manage some symptom clusters. Furthermore, hospital clowns might help improve psychological wellbeing in admitted children and adolescents with acute and chronic disorders, compared with those who received only standard care.

Positive distraction for children during burn wound care in Australia - An evaluation of the 'Captains on Call' pilot

INTRODUCTION

Burn wound care procedures can cause severe pain to the child, and distress for both the child and caregivers. We evaluated a new Starlight Children's Foundation program, 'Captains on Call', which aims to provide positive distraction during burn wound care procedures to reduce the child's anxiety and pain. This paper presents a preliminary evaluation, using a qualitative design, of Captains on Call at the Women's and Children's Hospital, Australia.

METHODS

We conducted interviews with caregivers (n = 18), patients (n = 6), nurses (n = 5) and Captain Starlights (n = 3). Interviews focused on program impact and recommendations for how to improve the program.

RESULTS

We identified seven themes: (1) positive distraction from pain and boredom, (2) benefit of additional support, (3) creating positive memories of the hospital, (4) catering for unique needs of each patient and family, (5) general appreciation, (6) importance of regular visits, and (7) a desire to expand the program. All caregivers, nurses and patients reported that they were likely to recommend the program to others.

CONCLUSION

This study provides early evidence to support the benefit of the Captains on Call program to families and health professionals, as well as the feasibility in providing this integrated care.

Effects of Therapeutic Clowning on Pain and Anxiety During Intrathecal Chemotherapy in Turkey

PURPOSE

The aim of the present study was to explore the effect of therapeutic clowning on pain and anxiety during intrathecal chemotherapy.

DESIGN & METHODS

The study was conducted using a quasi-experimental method with a pretest-posttest control group design. The study sample was composed of children between 7 and 12 years old (N = 78) who had been diagnosed with acute myeloid leukaemia and acute lymphoblastic leukaemia and were undergoing intrathecal chemotherapy in a hospital in Turkey. The study was conducted with children who received services at this hospital. The results were obtained from 74 children (i.e. 36 in the control group, 38 in the clown group). The data were collected with a questionnaire developed by the researchers, the Visual Analogue Scale (VAS) and the Faces Pain Rating Scale (FACES). VAS and FACES were used to measure pain and anxiety levels. Therapeutic clowning was applied to children in the intervention group. Analyses included percentage distributions, mean, chi-square, t-test, variance, and correlation analysis.

RESULTS

Results showed that children in the clown group had significantly lower pain and anxiety than children in the control group (p < .001).

CONCLUSIONS

According to the results, therapeutic clowning was effective in relieving the pain and anxiety of children between the ages of 7 and 12 years who undergone intrathecal chemotherapy.

PRACTICE IMPLICATIONS

Due to its positive effects, therapeutic clowning could be explore for use in other areas of paediatric nursing for the children between the ages of 7 and 12 years as a complementary treatment.

The Efficacy of Distraction Cards and Kaleidoscope for Reducing Pain During Phlebotomy: A Randomized Controlled Trial

PURPOSE

The purpose of this study was to determine the efficacy of distraction cards and a kaleidoscope in reducing pain during phlebotomy procedures among children aged 6 to 12.

DESIGN

This randomized controlled study involved intervention groups and a control group.

METHODS

Data were obtained by the use of an information form and the visual analog scale. Data were analyzed with descriptive statistics as well as Kruskal-Wallis, Wilcoxon, and post hoc tests.

FINDINGS

During the phlebotomy, children in the control group experienced more pain than children in the distraction cards group and kaleidoscope group (P < .001). There was no significant difference between pain scores of the two intervention groups (P > .05). Both methods were found to be effective in reducing pain.

CONCLUSIONS

It may be helpful to inform children and parents about the process before procedural interventions. Nurses would likely benefit from education on the use of distraction cards and kaleidoscope to be used during procedural interventions.

Measuring patient experiences in a Children's hospital with a medical clowning intervention: a case-control study

BACKGROUND

Because the healthcare sector is shifting to a customer-oriented approach, it is important to understand experiences of children as users of healthcare services. So far, studies that measure the influence of medical clowning on patient experiences are scarce. This study aims to measure experiences of children and their parents during day-surgery in hospital setting.

METHODS

A case-control study was conducted in a large Finnish children's hospital. Seventy children aged 4-17 years coming for a minor operative procedure including pre-operative cannula insertion prior to surgery were included. Thirty-eight children were exposed to the medical clowning intervention and 32 children (the reference group) did not receive exposure to medical clowning. A novel digital survey tool was used to measure patient experiences before and after the insertion of a venous cannula needed for anaesthesia. The children were asked about their emotions, anxiety levels, the pain from the cannula insertion and the best and worst things about the hospital. The parents were asked about their emotions, expectations and the fluency of the procedure and the hospital day.

RESULTS

Before the procedure, 32% or 36% of the children in the intervention group and 44% or 28% of those in the reference group expressed positive or neutral emotions, respectively. After the procedure, 76% or 63% of children in the intervention group or reference group, respectively, expressed positive emotions. The intervention group rated the medical clowns as the best aspect of the hospital day. Both groups reported that the best aspects of the hospital day were related to the nurses and food and the worst were related to waiting and pain. Most commonly the parents felt uncertainty, anxiety or calmness before the procedure and relief afterwards. Their expectations towards the procedure related to its success and the certainty of the diagnosis.

CONCLUSIONS

The results show a trend towards more positive emotions in children with exposure to medical clowning. The digital survey tool was suitable for gathering information about the experiences of children and their parents. Information on emotions and expectations of children and parents during a procedure is useful when improving the quality of healthcare services.

The effectiveness of web-based mobile health interventions in paediatric outpatient surgery: A systematic review and meta-analysis of randomized controlled trials

AIMS

To evaluate the effectiveness of web-based mobile health interventions on paediatric patients and their parents in the day surgery context, where the primary outcome was children's pre-operative anxiety and secondary outcomes were postoperative pain and parents' anxiety and satisfaction with entire course of the day surgery.

DESIGN

A systematic review and meta-analysis of randomized controlled trials.

DATA SOURCES

CENTRAL, CINAHL, Scopus, Ovid MEDLINE, and Web of Science were systematically searched without time limits (up to December 2018).

REVIEW METHODS

Studies were appraised using the Cochrane risk of bias tool. A random effect meta-analysis of children's pre-operative anxiety was performed.

RESULTS

Eight studies with a total of 722 patients were included in the analysis. The effectiveness of web-based mobile health interventions, including age-appropriate videos, web-based game apps, and educational preparation games made for the hospital environment, was examined in pre-operative settings. A meta-analysis (N = 560 children) based on six studies found a statistically significant reduction in pre-operative anxiety measured by the Modified Yale Pre-operative Anxiety Scale with a moderate effect size. Three studies reported parental satisfaction.

CONCLUSION

Web-based mobile health interventions can reduce children's pre-operative anxiety and increase parental satisfaction. Web-based mobile health interventions could be considered as non-pharmacological distraction tools for children in nursing. There is not enough evidence regarding the effectiveness of reducing children's postoperative pain and parental anxiety using similar interventions.

IMPACT

Web-based mobile health interventions reduce children´s pre-operative anxiety and could therefore be considered as non-pharmacological distraction tools for children in nursing.

'If I knew what was going to happen, it wouldn't worry me so much': Children's, parents' and health professionals' perspectives on information for children undergoing a procedure

Children undergoing procedures such as blood tests and X-rays experience less anxiety and upset if they are well prepared and informed. Currently the provision of information about procedures can be ad hoc and there are barriers to children understanding this information. This study explored the perspectives of 32 children undergoing procedures (aged between 8 and 12 years), 27 parents and 19 health professionals on the provision of preparatory information to children. Qualitative interviews, prompted by visual images, were thematically analysed. The three themes, 'accessing information', 'understanding information' and 'using information', resonated with the central tenets of health literacy. Children reported mainly accessing information second-hand through their parents and demonstrated misconceptions about their procedure. Children identified that procedural information would help them to know what was going to happen and enable them to feel less worried and scared about their procedure. This study highlights that children can have low levels of health literacy in relation to a planned procedure. Their health literacy in this context is heavily influenced by the adults (parents and health professionals) around them. There needs to be further work conducted, informed directly by children, to improve the health literacy of children attending hospital for planned procedures.

Acute Procedural Pain in Children: Intervention With the Hospital Clown

INTRODUCTION

Hospitalized children often describe needle-related procedures as the worst pain possible and such procedures may be emotionally traumatic. The use of hospital clowns (HCs) related to painful medical procedures in children may offer pain relief, but this has not been systematically evaluated. The objective of this study was to assess the effect of a therapeutic clown in comparison with standard care on the experience of pain in children receiving venipuncture.

MATERIALS AND METHODS

A sample of 116 children aged 4 to 15 years consecutively admitted to the hospital was allocated to either the experimental (presence of HC) or control group (standard care) before venipuncture. Self-reported pain after the procedure was assessed using the Faces Pain Scale combined with a 0 to 10 Numerical Rating Scale. Separate analysis was conducted in age groups from 4 to 6 (N=37) and 7 to 15 (N=74) years.

RESULTS

Without the clown present, the mean pain score (2.7±2.8) was not significantly different between the 2 age groups. Children aged 7 to 15 years had lower pain scores when the clown was present compared with the control group (P=0.025). Children aged 4 to 6 years had higher pain scores with the clown present, although the difference was not statistically significant (P=0.054). Children with pain (N=49) or previous experiences with venipuncture (N=56) did not score pain significantly differently.

DISCUSSION

Assessing the pain experience of children receiving venipuncture with the presence of an HC indicates a pain relieving effect for children older than 6 years. However, future studies should carefully study the effects on younger children where mixed effects may be present.

The impact of medical clowns exposure over postoperative pain and anxiety in children and caregivers: An Israeli experience

While postoperative pain management was shown to reduce unwanted physiological and emotional outcomes, pediatric postoperative pain management remains suboptimal. Medical-clowns were shown to be beneficial in many medical contexts including reduction of stress, anxiety and pain. This study was set to assess the effectiveness of medical-clowns on pediatric postoperative pain reduction. Children age 4 or above, planned for elective hernia repair surgery were recruited. Children were randomly divided to a control or medicalclown escorted groups. Demographical and clinical data were collected using questionnaires and electronic sheets. Children escorted by clowns reported lower levels of pain upon admittance, discharge and 12- hours post-surgery. Statistically significant reduction of parental distress and significantly higher serum cortisol levels were observed in the clown-therapy group. Although small, our study supports the possibility that preoperative medical-clown therapy might be a cheap, safe and yet beneficial method for postoperative pain reduction.

An ongoing WE: A focused ethnographic study of the relationship between child and hospital clown during recurrent pain‐related procedures and conditions

Aim

This study explored the interaction between child and hospital clown during recurrent hospitalizations for repeated pain‐related procedures and conditions.

Background

Despite improvements in the management of pain in hospitalized children, procedural pain in particular is a common experience for hospitalized children, and they continue to report undertreated pain. Hospital clowns are widely used as a nonpharmacological intervention in hospitalized children. Little research has examined the influence of hospital clowns during recurrent hospitalizations on repeated painful procedures.

Design and methods

Ethnographic fieldwork using focused ethnography was conducted. Data were collected during October–December 2017 using participant observation and informal interviews with children at one pediatric unit at a Danish university hospital. Data include 61 interactions between children aged 4–14 years and hospital clowns. The participants comprised 13 children undergoing recurrent hospitalizations. The data were coded using thematic analysis, and the research team verified the resulting themes.

Results

The overarching theme was defined as An ongoing WE, based on two identified themes, that is, Stronger in a WE and Hope in the WE. The WE was characterized by a responsive interaction between the child and clown, which evolved over the course of an ongoing relationship.

Conclusion

This study demonstrates how an ongoing WE was constructed with children during repeated painful procedures and conditions. Specifically, the study emphasizes the importance of developing a trusting relationship on the child's terms. Children seemed to experience enhanced coping with painful procedures during the recurring hospital clown encounters, thus reinforcing their competence and hope for coping with future painful procedures. These findings may improve psychosocial care for hospitalized children undergoing repeated painful procedures and conditions and may facilitate multidisciplinary initiatives, such as nurses’ advocacy for the inclusion of hospital clowns during recurrent hospitalizations for repeated painful procedures to ensure optimal pain management.

Clowning in children undergoing potentially anxiety-provoking procedures: a systematic review and meta-analysis

BACKGROUND

The operation areas of clowns in the medical context are multifaceted. Clowning in children undergoing surgery has been shown to be able to lessen children's anxiety. Hence, our aim was to assess the effectiveness of clowning on anxiety in children undergoing potentially anxiety-provoking procedures.

METHODS

We searched MEDLINE, CENTRAL, and EMBASE for randomized controlled trials (RCTs) in December 2018. The primary outcome was children's anxiety. We used the Cochrane risk of bias tool to assess risk of bias of the included studies.

RESULTS

We found eleven RCTs including 733 children. Their risk of bias was relatively high. Children undergoing clowning were significantly less anxious in preoperative time compared to parental presence or no intervention (mean difference (MD) - 7.16; 95% CI - 10.58, - 3.75) and in operation, induction, or patient room (MD - 20.45; 95% CI - 35.54, - 5.37), but not during mask application or physician examination (MD 2.33; 95% CI - 4.82, 9.48). Compared with midazolam, children's anxiety was significantly lower in preoperative time (MD - 7.60; 95% CI - 11.73, - 3.47), but not in the induction room (MD - 9.63; 95% CI - 21.04, 1.77).

CONCLUSIONS

Clowning seems to lower children's anxiety, but because of the increased risk of bias of included studies and the very low quality of evidence, these results should be considered with caution.

"WE do it together!" An Ethnographic Study of the Alliance Between Child and Hospital Clown During Venipunctures

PURPOSE

Hospital clowns are widely used as a means of non-pharmacological intervention in the treatment of hospitalized children. However, little research has examined the impact of clowns on common painful needle-related procedures. This study explored children's pain experience and their ability to cope during a venipuncture while interacting with a clown in the acute admission unit.

DESIGN AND METHODS

An ethnographic fieldwork study was conducted. Data were collected over a 10-month period through participant observation and informal interviews, supplemented by video recordings. The participants comprised 38 acutely admitted children aged 4 to 15 years undergoing a venipuncture in the presence of a hospital clown. Analysis was structured in three stages: before venipuncture; during venipuncture; and after venipuncture.

RESULTS

The development of a responsive interaction between child and clown, identified as a WE, was found to be beneficial to the child during venipuncture procedure. The WE was characterized by three themes "How do WE do this together?"; "WE are together"; and "I/WE did it!"

CONCLUSIONS

The study emphasizes the importance of a WE established between child and hospital clown from the first encounter until a final evaluation. This WE was verbalized repeatedly by the clown and the child and was essential in shaping a tailored approach which met the needs of each child. This approach seemed to strengthen the child's competence in pain management and ability to cope, thus building competence for future venipunctures.

PRACTICE IMPLICATIONS

Establishing a WE might advance the psychosocial care of hospitalized children undergoing acute painful procedures.

Systematic review protocol examining the effectiveness of hospital clowns for symptom cluster management in paediatrics

INTRODUCTION

Clown intervention may playing an important complementary role in paediatric care and recovery. However, data on its utility for symptom cluster management of hospitalised children and adolescents in acute and chronic disorders are yet to be critically evaluated. As clinicians strive to minimise the psychological burden during hospitalisation, it is important that they are aware of the scientific evidences available regarding clown intervention for symptom management. We aim to provide quality evidence for the effectiveness of clown intervention on symptom cluster management in paediatric inpatients, both in acute and chronic conditions.

METHODS AND ANALYSIS

A systematic review of randomised controlled trials (RCTs) and non-randomised controlled trials (NRCTs) will be conducted. MEDLINE, Web of Science, Cochrane Library, Science Direct, PsycINFO, CINAHL, LILACS and SciELO databases will be searched from January 2000 to December 2018. Primary outcomes will include measures related with the effect of clown intervention on symptom cluster of paediatric inpatients (anxiety, depression, pain, fatigue, stress and psychological, emotional responses and perceived well-being). Study selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the methodological appraisal of the studies will be assessed by the Jadad Scale as well as Cochrane Risk-of-Bias Tool for RCTs, and Risk-of-Bias In Non-Randomized Studies Tool for NRCTs. A narrative synthesis will be conducted for all included studies. Also, if sufficient data are available, a meta-analysis will be conducted. The effect sizes will be generated using Hedges' g score for both fixed and random effect models. I 2 statistics will be used to assess heterogeneity and identify their potential sources.

ETHICS AND DISSEMINATION

As it will be a systematic review, without human beings involvement, there will be no requirement for ethical approval. Findings will be disseminated widely through peer-reviewed publication and in various media, for example, conferences, congresses or symposia.

Feeling happy and carefree: a qualitative study on the experiences of parents, medical clowns and healthcare professionals with medical clowns

Purpose: To explore the effect of medical clowns and its relevant actors and conditions.

Method: Semi-structured interviews were conducted with fourteen parents who had experiences with medical clowns in the Netherlands. Four focus groups were held with seven medical clowns and 25 healthcare professionals. The interviews and focus groups were audio-recorded and transcribed verbatim. Content analysis was used to analyse the data.

Results: Concerning the clown effect, we distinguished the following themes: happiness, distraction, carefree feeling and activation. This effect depended upon clown characteristics (appearance, tailoring, low-key play, making an effort); child characteristics (age, autonomy, fear, living cut off from society, communication); parent characteristics (autonomy, attitude); healthcare professional characteristics (attitude, communication); and organizational conditions (timing and planning, collaboration, accessibility, awareness).

Conclusion: This study shows that medical clowns are of value for children with serious illnesses or mental disabilities in several care settings. An asset of medical clowns is that they tailor their play to the child and situation.Support of and communication with parents and healthcare professionals is critical. The proposed model of the clown effect can help shape future research. The results can help medical clown organizations to enhance their services and optimize clown encounters.

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.

Laughing away the pain: A narrative review of humour, sense of humour and pain

BACKGROUND AND OBJECTIVE

The link between humour and sense of humour with pain has been a topic of research for decades. The purpose of the present article was to review the different studies that have been conducted to date on the association between humour and sense of humour with pain.

DATABASES AND DATA TREATMENT

The literature search was conducted using the PubMed, Science Direct and ProQuest databases. Forty-one studies were reviewed, and the results are summarized and structured into three sections: experimental pain, chronic pain and pain in children.

RESULTS

For experimental pain, the findings support the idea that humorous distractions, such as watching a comedy clip, increase pain tolerance, although most of the studies indicate that other non-humorous distractions produce similar effects. Regarding chronic pain, humour has been studied as a way of coping with pain and the emotional distress produced by chronic pain conditions. The results of correlational studies show significant associations between the use of humour and main variables such as anxiety and catastrophizing. Finally, concerning pain in children, similar findings to those described for the previous sections have been reported, with a notable presence of studies on clinic clown interventions, which promote emotional well-being among children and their parents, although their effectiveness in pain reduction is controversial.

CONCLUSIONS

The study of the link between humour and pain is still on an early stage, and overcoming the limitations of previous studies is required to strengthen the promising results that have been observed up to date.

SIGNIFICANCE

This review summarizes all main findings regarding humour, sense of humour and pain up until the first half of 2018 and offers a list of aspects to be considered in further studies regarding the link of humour and pain to contribute to a more systematic research.

The effect of medical clowns on performance of spirometry among preschool aged children

INTRODUCTION

Medical clowns (MCs) are known to assist in reducing pain and alleviating anxiety. The objective of this study is to evaluate the ability of MCs to assist preschoolers in performing spirometry.

METHODS

A prospective, randomized controlled trial. Children aged 3-6 years participated. After a first spirometry, children were divided into two groups: the first performed a second spirometry with an MC. The second repeated spirometry with the technician. Primary outcome was second spirometry values compared between the groups. Secondary outcome were change in spirometry values within groups, and difference between the groups.

RESULTS

A total of 140 children participated. The groups did not differ in age, sex, mother tongue, or weight. Nor in mean FVC (MC 89.2% ± 16.7, control 89.5% ± 16.3) mean FEV1 (MC 91.3% ± 15.6, control 94.2% ± 16.8), and expiratory time (MC 1.58 ± 0.43, control 1.7 ± 0.44) in first spirometry. In second spirometry the control group had a similar FVC, FEV1, and expiratory time. The MC group had a significant improvement in all parameters: FVC: MC 95.3% ± 15.5, control 89.3% ± 19.1, FEV1: MC 98.0% ± 15.6, control 91.8% ± 19.3, and expiratory time MC 1.96 ± 0.55, control 1.84 ± 0.52. The differences between the groups between first and second attempt were significant (P-value FVC 0.000, FEV1 0.000, expiratory time 0.003).

DISCUSSION

MCs improved performance of spirometry among preschoolers. It is possible that laughter and relief of stress had a physiological effect. Further studies are required to better establish the ability of MCs to improve active participation and to better understand whether the mechanism of the improvement is better cooperation or true physiological change.

Distraction Technique for pain reduction in Peripheral Venous Catheterization: randomized, controlled trial

Background and aim of the work: Procedural pain during Peripheral Venous Catheterization (PVC) is a significant issue for patients. Reducing procedure-induced pain improves the quality of care and reduces patient discomfort. We aimed to compare a non-pharmacological technique (distraction) to anaesthetic cream (EMLA) for the reduction of procedural pain during PVC, in patients undergoing Computerized Tomography (CT) or Nuclear Magnetic Resonance (NMR) with contrast. Methods: This is a Prospective, Randomized Controlled Trial. The study was carried out during the month of October 2015. A total of 72 patients undergoing PVC were randomly assigned to the experimental group (distraction technique, n=36) or control group (EMLA, n=36). After PVC, pain was evaluated by means of the numeric pain-rating scale (NRS). Pain perception was compared by means of Mann-Whitney Test. Results: The average pain in the distraction group was 0.69 (SD±1.26), with a median value of 0. The average pain in the EMLA group was 1.86 (SD±1.73), with a median value of 2. The study showed a significant improvement from the distraction technique (U=347, p<.001, r=.42) with respect to the local anaesthetic in reducing pain perception. Conclusions/Implication for practice: Distraction is more effective than local anaesthetic in reducing of pain-perception during PVC insertion. This study is one of few comparing the distraction technique to an anaesthetic. It confirms that the practitioner-patient relationship is an important point in nursing assistance, allowing the establishment of trust with the patient and increasing compliance during the treatment process.

Disaster zones-should we be clowning around?

Medical clowns have an important role in helping patients cope with their pain and distress. This is especially true in the pediatric population. However, their activity in a disaster area is unheard of. Following the Nepal earthquake in 2015, the Israeli field hospital set up in Kathmandu, Nepal was joined by five volunteer medical clowns. They were active in all parts of the field hospital. Following the hospital's activity, an online questionnaire was sent to the field hospital members to assess the impact of medical clowning on the hospital in general and its members' individual performance. Physicians and nurses found that medical clowning had a positive impact both generally and personally. (65.4 and 78.3% respectively on general impact.) Personnel that were not previously exposed to medical clowning also found them to have a positive impact; however, they were less likely to view it as impacting their personal performance.

CONCLUSION

Medical teams in disaster areas may benefit from the presence of medical clowns. What is known about this topic: • Medical clowns are used for alleviation and distraction in painful and distressful medical procedures and treatments. Its positive effect on patients, and their families are well established.

WHAT THIS STUDY ADDS

• This is the first description of medical clowning in a disaster area. In addition, the impact of medical clowning on the medical staff working in a disaster area is evaluated. No previous studies have explored the impact of medical clowns on the medical staff.

A cross-cultural perspective of medical clowning: comparison of its effectiveness in reducing pain and anxiety among hospitalized Bedouin and Jewish Israeli children

PURPOSE

Medical clowning has proven effective for reducing pain, anxiety, and stress, however, its differential effects on children from different cultures have not yet been researched. This study evaluated the effects of medical-clowning intervention on anxiety and pain among Jewish and Bedouin children, and anxiety among their parents, in southern Israel.

PATIENTS AND METHODS

The study was conducted in hospital pediatric departments and employed a pre-post design involving quantitative and qualitative methods. The study included 89 children whose ages ranged from 7.5 to 12 years (39 Jewish and 50 Bedouin) and 69 parents (19 Jewish and 50 Bedouin). Questionnaires assessing pain, anxiety, and demographics were used at the pre-intervention stage and pain, anxiety, and enjoyment of different aspects of the intervention were evaluated following the intervention. The intervention stage lasted for 8-10 minutes and included the use of word play, body language, and making faces, as well as the use of props brought by the clown. Semi-structured interviews were also conducted at the post-intervention stage.

RESULTS

The intervention reduced pain and anxiety among both groups of children and reduced anxiety among both groups of parents. However, anxiety levels were reduced more significantly among Bedouin children. The nonverbal components of the clowns' humor were most central, but it was the verbal components that mediated the reduction in anxiety among the Bedouin children.

CONCLUSION

This study underscored the effectiveness and importance of medical clowning in reducing pain and anxiety among children in different cultural contexts. Moreover, the issue of culturally appropriate humor was underscored and implications for intercultural clown training are discussed.

Is there a role for clowns in paediatric intensive care units?

Hospital clowning is a programme in healthcare facilities involving visits from specially trained actors. In the paediatric intensive care unit (PICU), clowning may appear inappropriate and less intuitive. The patient could appear too ill and/or sedated, the environment too crowded or chaotic and the parents too stressed. Relying on our experience with professionally trained clowns both in France and Canada, the purpose of this article is to offer a model for hospital clowning and to suggest standards of practice for the implementation of clowning in PICUs. In this work, we provide a framework for the implementation of clown care in the PICU, to overcome the challenges related to the complex technical environment, the patient's critical illness and the high parental stress levels. Regardless of the specifics of the PICU, our experience suggests that professional clown activity is feasible, safe and can offer multiple benefits to the child, his/her parents and to hospital personnel. Due to the specific challenges in the PICU, clowns must be educated and prepared to work in this highly specialised environment. We stress that prior to clowning in a PICU, professional performers must be highly trained, experienced, abide by a code of ethics and be fully accepted by the treating healthcare team.

Acute pain management: acetaminophen and ibuprofen are often under-dosed

Most children with pain are managed by either acetaminophen or ibuprofen. However, no study has so far investigated if children are prescribed adequate doses of acetaminophen or ibuprofen in emergency department. Aim of this retrospective study was to investigate the prevalence of under-dosage of these drugs in children presenting with pain in emergency department. Children initially prescribed with acetaminophen or ibuprofen for pain management were included. The χ ² automatic interaction detection method was used considering the percentage variation from the minimum of the appropriate dose as dependent variable while prescribed drug, age, gender, body weight, type of hospital (pediatric or general), and availability of internal guidelines on pediatric pain management in the emergency department as independent variables. Data on 1471 children managed for pain were available. Under-dosage was prescribed in 893 subjects (61%), of whom 577 were prescribed acetaminophen and 316 ibuprofen. The use of acetaminophen suppositories, body weight <12 kg or >40 kg, and the use of oral ibuprofen identified clusters of children associated with under-dosage prescription.

CONCLUSION

Prescription of acetaminophen and ibuprofen was frequently under-dosed. The use of suppositories, lower and higher body weight, and the use of ibuprofen were associated with under-dosage. Under-dosing may reflect prescription of anti-pyretic doses.

CLINICAL TRIAL REGISTRATION

Agenzia Italiana del Farmaco-Observational Study Register (RSO). Registration code: PIERRE/1 What is Known: • Pain is frequent in children presented to emergency department. • International recommendations on pain management are often not implemented. What is New: • Acetaminophen and ibuprofen were frequently underdosed in children prescribed for pain in the Italian emergency departments. • Under-dosage may be related to the habit of using acetaminophen and ibuprofen in the recommended range for fever treatment.
