Improving the assessment of pediatric chronic pain: harnessing the potential of electronic diaries

"Asking Too Much?": Randomized N-of-1 Trial Exploring Patient Preferences and Measurement Reactivity to Frequent Use of Remote Multidimensional Pain Assessments in Children and Young People With Juvenile Idiopathic Arthritis

Background

Remote monitoring of pain using multidimensional mobile health (mHealth) assessment tools is increasingly being adopted in research and care. This assessment method is valuable because it is challenging to capture pain histories, particularly in children and young people in diseases where pain patterns can be complex, such as juvenile idiopathic arthritis (JIA). With the growth of mHealth measures and more frequent assessment, it is important to explore patient preferences for the timing and frequency of administration of such tools and consider whether certain administrative patterns can directly impact on children’s pain experiences.

Objective

This study aimed to explore the feasibility and influence (in terms of objective and subjective measurement reactivity) of several time sampling strategies in remote multidimensional pain reporting.

Methods

An N-of-1 trial was conducted in a subset of children and young people with JIA and their parents recruited to a UK cohort study. Children were allocated to 1 of 4 groups. Each group followed a different schedule of completion of MPT for 8 consecutive weeks. Each schedule included 2 blocks, each comprising 4 different randomized time sampling strategies, with each strategy occurring once within each 4-week block. Children completed MPT according to time sampling strategies: once-a-day, twice-a-day, once-a-week, and as-and-when pain was experienced. Adherence to each strategy was calculated. Participants completed the Patient-Reported Outcomes Measurement Information System Pain Interference Scale at the end of each week to explore objective reactivity. Differences in pain interference scores between time sampling strategies were assessed graphically and using Friedman tests. Children and young people and their parents took part in a semistructured interview about their preferences for different time sampling strategies and to explore subjective reactivity.

Results

A total of 14 children and young people (aged 7-16 years) and their parents participated. Adherence to pain reporting was higher in less intense time sampling strategies (once-a-week=63% [15/24]) compared with more intense time sampling strategies (twice-a-day=37.8% [127/336]). There were no statistically significant differences in pain interference scores between sampling strategies. Qualitative findings from interviews suggested that children preferred once-a-day (6/14, 43%) and as-and-when pain reporting (6/14, 43%). Creating routine was one of the most important factors for successful reporting, while still ensuring that comprehensive information about recent pain was captured.

Conclusions

Once-a-day pain reporting provides rich contextual information. Although patients were less adherent to this preferred sampling strategy, once-a-day reporting still provides more frequent assessment opportunities compared with other less intense or overburdensome schedules. Important issues for the design of studies and care incorporating momentary assessment techniques were identified. We demonstrate that patient reporting preferences are key to accommodate and are important where data capture quality is key. Our findings support frequent administration of such tools, using daily reporting methods where possible.

The Gastrointestinal Pain Pointer: A Valid and Innovative Method to Assess Gastrointestinal Symptoms

Abdominal pain is a chronic condition experienced by approximately 20% of individuals in the United States. The purpose of the study was to assess the validity of the Gastrointestinal Pain Pointer as a measure of abdominal pain intensity. A prospective longitudinal time-series study design was utilized. The sample included 93 outpatients (58.1% female). Participants met Rome III criteria for irritable bowel syndrome (n = 32) or were healthy controls (n = 61). The Gastrointestinal Pain Pointer, a new electronic pain assessment tool, was used to assess self-reported abdominal pain intensity among participants before and after ingestion of an intestinal permeability test solution across 11 time points over a 5-hour time period. The results were compared with the Short-Form McGill Pain Questionnaire. The Gastrointestinal Pain Pointer was found to be valid in the assessment of abdominal pain intensity. The tool is a novel and valid measure of abdominal pain intensity that enhances the ability for clinicians to better quantify, in real time, patient-related pain outcomes for both clinical care and research.

Linking Pediatrics Patients and Nurses With the Pharmacy and Electronic Health Record System Through the Inpatient Television: A Novel Interactive Pain-Management Tool

OBJECTIVES

Implement a novel pain-management interface that is used to bring real-time, patient-reported pain assessments to the inpatient television and evaluate the impact of implementation on the pain-management clinical workflow, patient engagement, and nursing pain reassessments.

METHODS

We developed a pain-management tool interfacing 4 stand-alone technologies: a television-based, interactive patient care system; electronic health record system; nursing call system; and pharmacy inventory-management system. The workflow is triggered when pain medications are dispensed by sending an automatic pain assessment rating question via the patient's television at a predefined time. To measure the effects of implementation, we calculated patient and/or parent use rates and pain reassessment timely documentation rates. Data were extracted from the electronic health record for a period of 22 months and covered pre- and postimplementation.

RESULTS

A total of 56 931 patient records were identified during the study period, representing 2447 unique patients. In total, 608 parents and/or patients reported their pain through the tool. Use rates were 6.5% for responding to the pain rating prompt and 13.3% for the follow-up prompt, in which additional nonpharmacologic strategies to eliminate pain were offered. A modest increase was found in the mean timely documentation rates on the basis of nursing documentation standards (26.1% vs 32.8%, a percentage increase of 25.7%; P < .001) along with decreased median time to pain reassessment documentation (29 minutes versus 25 minutes, a percentage decrease of 13.8%; P < .001).

CONCLUSIONS

With this novel tool, we offer a potentially scalable approach in supporting the pain-management clinical workflow, integration of technologies, and promoting of patient and/or parent engagement in the inpatient setting.

Chronic Pain Assessments in Children and Adolescents: A Systematic Literature Review of the Selection, Administration, Interpretation, and Reporting of Unidimensional Pain Intensity Scales

BACKGROUND

Advances in pain assessment approaches now indicate which measures should be used to capture chronic pain experiences in children and adolescents. However, there is little guidance on how these tools should best be administered and reported, such as which time frames to use or how pain scores are categorised as mild, moderate, or severe.

OBJECTIVE

To synthesise current evidence on unidimensional, single-item pain intensity scale selection, administration, interpretation, and reporting.

METHODS

Databases were searched (inception: 18 January 2016) for studies in which unidimensional pain intensity assessments were used with children and adolescents with chronic pain. Ten quality criteria were developed by modifying existing recommendations to evaluate the quality of administration of pain scales most commonly used with children.

RESULTS

Forty-six studies met the inclusion criteria. The highest score achieved was 7 out of a possible 10 (median: 5; IQR: 4-6). Usage of scales varied markedly in administrator/completer, highest anchors, number of successive assessments, and time referent periods used.

CONCLUSIONS

Findings suggest these scales are selected, administered, and interpreted inconsistently, even in studies of the same type. Furthermore, methods of administration are rarely reported or justified making it impossible to compare findings across studies. This article concludes by recommending criteria for the future reporting of paediatric chronic pain assessments in studies.

Construct validity and reliability of a real-time multidimensional smartphone app to assess pain in children and adolescents with cancer

We evaluated the construct validity (including responsiveness), reliability, and feasibility of the Pain Squad multidimensional smartphone-based pain assessment application (app) in children and adolescents with cancer, using 2 descriptive studies with repeated measures. Participants (8-18 years) undergoing cancer treatment were drawn from 4 pediatric cancer centers. In study 1, 92 participants self-reported their level of pain twice daily for 2 weeks using the Pain Squad app to assess app construct validity and reliability. In study 2, 14 participants recorded their level of pain twice a day for 1 week before and 2 weeks after cancer-related surgery to determine app responsiveness. Participants in both studies completed multiple measures to determine the construct validity and feasibility of the Pain Squad app. Correlations between average weekly pain ratings on the Pain Squad app and recalled least, average, and worst weekly pain were moderate to high (0.43-0.68). Correlations with health-related quality of life and pain coping (measured with PedsQL Inventory 4.0, PedsQL Cancer Module, and Pain Coping Questionnaire) were -0.46 to 0.29. The app showed excellent internal consistency (α = 0.96). Pain ratings changed because of surgery with large effect sizes between baseline and the first week postsurgery (>0.85) and small effect sizes between baseline and the second week postsurgery (0.13-0.32). These findings provide evidence of the construct validity, reliability, and feasibility of the Pain Squad app in children and adolescents with cancer. Use of real-time data capture approaches should be considered in future studies of childhood cancer pain.

Pediatric Pain Measurement, Assessment, and Evaluation

Assessment provides the foundation for diagnosis, selection of treatments, and evaluation of treatment effectiveness for pediatric patients with acute, recurrent, and chronic pain. Extensive research has resulted in the availability of a number of valid, reliable, and recommended tools for assessing children's pain. Yet, evidence suggests children's pain is still not optimally measured or treated. In this article, we provide an overview of pain evaluation for premature neonates to adolescents. The difference between pain assessment and measurement is highlighted; and the key steps to follow are identified. Information about self-report and behavioral pain assessment tools appropriate for children are provided; and factors to be considered when choosing a specific one are outlined. Finally, we preview future approaches to personalized pain medicine in pediatrics that include harnessing the use of potential digital health technologies and genomics.

On the electronic measurement of pain intensity: Can we use different pain intensity scales interchangeably?

The objective of this work was to study the agreement between four pain intensity scales when administered electronically: the Numerical Rating Scale-11, the Faces Pain Scale-Revised, the Visual Analogue Scale and the Coloured Analogue Scale. In all, 180 schoolchildren between 12 and 19 years old participated in the study. They had to report the maximum intensity of their most frequent pain using the electronic versions of the four scales. Agreement was calculated using the Bland–Altman method. Results show that the electronic versions of Numerical Rating Scale-11, Coloured Analogue Scale and Visual Analogue Scale can be used interchangeably.

A smartphone version of the Faces Pain Scale-Revised and the Color Analog Scale for postoperative pain assessment in children

BACKGROUND

Effective pain assessment is essential during postoperative recovery. Extensive validation data are published supporting the Faces Pain Scale-Revised (FPS-R) and the Color Analog Scale (CAS) in children. Panda is a smartphone-based application containing electronic versions of these scales.

OBJECTIVES

To evaluate agreement between Panda and original paper/plastic versions of the FPS-R and CAS and to determine children's preference for either Panda or original versions of these scales.

METHODS

ASA I-III children, 4-18 years, undergoing surgery were assessed using both Panda and original versions of either the FPS-R or CAS. Pain assessments were conducted within 10 min of waking from anesthesia and 30 min later.

RESULTS

Sixty-two participants, median (range) age 7.5 (4-12) years, participated in the FPS-R trial; Panda scores correlated strongly with the original scores at both time points (Pearson's r > 0.93) with limits of agreement within clinical significance (80% CI). Sixty-six participants, age 13 (5-18) years, participated in the CAS trial. Panda scores correlated strongly with the original scores at both time points (Pearson's r > 0.87); mean pain scores were higher (up to +0.47 out of 10) with Panda than with the original tool, representing a small systematic bias, but limits of agreement were within clinical significance. Most participants who expressed a preference preferred Panda over the original tool (81% of FPS-R, 76% of CAS participants).

CONCLUSION

The Panda smartphone application can be used in lieu of the original FPS-R and CAS for assessment of pain in children. Children's preference for Panda may translate to improved cooperation with self-report of pain.

Agreement between verbal and electronic versions of the numerical rating scale (NRS-11) when used to assess pain intensity in adolescents

OBJECTIVES

Electronic pain measures are becoming common tools in the assessment of pediatric pain intensity. The aims of this study were (1) to examine the agreement between the verbal and the electronic versions of the 11-point Numerical Rating Scale (NRS-11) (vNRS-11 and eNRS-11, respectively) when used to assess pain intensity in adolescents; and (2) to report participants' preferences for each of the 2 alternatives.

MATERIALS AND METHODS

A total of 191 school children enrolled in grades 7 to 11 (mean age, 14.61; range, 12 to 18) participated. They were asked to report the highest intensity of the most frequent pain that they had experienced during the last 3 months using both the vNRS-11 and the eNRS-11. Agreement analyses were carried out using: (1) the Bland-Altman method, with confidence intervals (CI) of both 95% and 80%, and a maximum limit of agreement of ±1; and (2) weighted intrarater κ-coefficients between the ratings for each participant on the vNRS-11 and eNRS-11.

RESULTS

The limits of agreement at 95% fell outside the limit established a priori (scores ranged from -1.42 to 1.69), except for participants in grade 11 (-0.80, 0.88). Meanwhile, the limits of agreement at 80% CI fell inside the maximum limit established a priori (scores ranged from -0.88 to 0.94), except for participants in grade 8 (Supplemental Digital Content 2, http://links.lww.com/CJP/A97) (-0.88, 1.16). The κ-coefficients ranged from 0.786 to 0.912, indicating "almost perfect" agreement. A total of 83% of participants preferred the eNRS-11.

DISCUSSION

Pain intensity ratings on the vNRS-11 and eNRS-11 seem to be comparable, at least for the 80% CI.

Pain Associated with Wound Care Treatment among Buruli Ulcer Patients from Ghana and Benin

Buruli ulcer (BU) is a necrotizing skin disease caused by Mycobacterium ulcerans. People living in remote areas in tropical Sub Saharan Africa are mostly affected. Wound care is an important component of BU management; this often needs to be extended for months after the initial antibiotic treatment. BU is reported in the literature as being painless, however clinical observations revealed that some patients experienced pain during wound care. This was the first study on pain intensity during and after wound care in BU patients and factors associated with pain. In Ghana and Benin, 52 BU patients above 5 years of age and their relatives were included between December 2012 and May 2014. Information on pain intensity during and after wound care was obtained during two consecutive weeks using the Wong-Baker Pain Scale. Median pain intensity during wound care was in the lower range (Mdn = 2, CV = 1), but severe pain (score > 6) was reported in nearly 30% of the patients. Nevertheless, only one patient received pain medication. Pain declined over time to low scores 2 hours after treatment. Factors associated with higher self-reported pain scores were; male gender, fear prior to treatment, pain during the night prior to treatment, and pain caused by cleaning the wound. The general idea that BU is painless is incorrect for the wound care procedure. This procedural pain deserves attention and appropriate intervention.

Overview of neurodevelopment and pain research, possible treatment targets

Pain is a common presenting and often persistent symptom for children with rheumatological disease. Pain is not clearly related to disease severity in children with inflammatory juvenile idiopathic arthritis, and presentations of non-inflammatory musculoskeletal pain are common but there is limited evidence to guide management. Pain assessment must extend beyond measures of pain severity to more fully evaluate characteristics of pain, functional impact and psychosocial effects and family interactions. Evaluation of mechanisms of joint pain in adults has identified potential treatment targets, but additional studies are required as the acute and long-term impacts of pain and injury change during postnatal development. Genotyping, sensory evaluation and neuroimaging may better characterize chronic musculoskeletal pain, identify high-risk groups and/or provide additional outcome measures to monitor disease and treatment progress. An integrated approach to management is required to effectively select and target interventions, reduce pain and disability and improve long-term outcome.

Refinement of the symptom screening in pediatrics tool (SSPedi)

Background:

Objective was to evaluate and refine a new instrument for paediatric cancer symptom screening named the Symptom Screening in Pediatrics Tool (SSPedi).

Methods:

Respondents were children 8–18 years of age undergoing active cancer treatment and parents of eligible children. Respondents completed SSPedi once and then responded to semi-structured questions. They rated how easy or difficult SSPedi was to complete. For items containing two concepts, we asked respondents whether concepts should remain together or be separated into two questions. We also asked about each item's importance and whether items were missing. Cognitive probing was conducted in children to evaluate their understanding of items and the response scale. After each group of 10 children and 10 parents, responses were reviewed to determine whether modifications were required. Recruitment ceased with the first group of 10 children in which modifications were not required.

Results:

Thirty children and 20 parents were required to achieve a final version of SSPedi. Fifteen items remain in the final version; the score ranges from 0 to 60.

Conclusions:

Using opinions of children with cancer and parents of paediatric cancer patients, we successfully developed a symptom screening tool that is easy to complete, is understandable and demonstrates content validity.

Developments in the use of e-health for chronic pain management

SUMMARY Recognition that changes are required in how chronic conditions are managed, combined with advances in technology, has led to the emergence of e-health as a possible solution. This selective review seeks to illustrate some of the ways in which e-health has been applied to chronic pain. Examples of technology use are provided within the areas of information provision, assessment and monitoring, and remote therapy, and the various strengths and weaknesses associated with each method are highlighted. One of the main concerns is that, despite enthusiastic promises, evidence of e-health for pain management is often based on small numbers and few randomized controlled trials. However, the situation is improving, especially within the field of internet-based interventions where the number of higher quality trials is increasing, and results to date are encouraging. A sense of cautious optimism seems reasonable when considering the potential of e-health for the management of chronic pain.

Using an electronic pain diary to better understand pain in children and adolescents with arthritis

Summary 

AIM

To explore the pain experience of youths (9-18 years old) with juvenile idiopathic arthritis, using a real-time data capture electronic pain diary.

MATERIALS & METHODS

A descriptive study design with repeated measures was used. A total of 76 youths, aged 9-18 years old with juvenile idiopathic arthritis were recruited from a Canadian pediatric tertiary care center and asked to record their pain three times a day for 2 weeks using the e-Ouch(©) pain diary.

RESULTS

On average, participants reported mild levels of pain intensity, unpleasantness and interference, as well as stiffness and mild-to-moderate levels of fatigue. Interference of stiffness and pain with activities of daily living were significantly higher in the morning versus the afternoon and evening; while fatigue was significantly higher in the morning and evening compared with the afternoon.

CONCLUSION

Real-time data capture approaches can be used enable a better understanding of how pain and other symptoms in youths with juvenile idiopathic arthritis change within and across days, and how best to treat them. Valuable next steps include incorporating the e-Ouch pain diary into an everyday clinical setting to measure patient outcomes.

Development and initial evaluation of electronic Children's International Mucositis Evaluation Scale (eChIMES) for children with cancer

PURPOSE

We previously developed a pediatric-specific measure of oral mucositis named the Children's International Mucositis Evaluation Scale (ChIMES). Availability as an electronic version may improve self-report response rates. The objectives were to develop an electronic version of ChIMES (eChIMES) and to determine whether the instrument is easy to use, understandable, and suitable for measuring mucositis among children and adolescents with cancer.

METHODS

Development of eChIMES was on an iPad; the initial version was piloted with ten children to refine instructions for use and presentation. A crosssectional study then was conducted and included English-speaking children and adolescents 8-18 years of age receiving active treatment for cancer. Participants were shown eCHIMES and were asked to complete it. Questions elicited whether they found eChIMES easy or difficult to use, easy or difficult to understand, and suitable (a good way) for children with cancer to monitor mucositis. Outcomes were rated using five-point ordinal scales.

RESULTS

Following the development and initial refinement of eChIMES, 40 children were enrolled. Median age was 12.4 (range, 8.0 to 17.8) years. The instrument was found to be easy or very easy to use and understood by 40 (100 %) and 38 (95 %) participants, respectively. The application was considered suitable or very suitable for measuring mucositis by 37 (92 %).

CONCLUSIONS

We found that eChIMES was easy to use, understandable, and suitable for monitoring mucositis among children with cancer. Incorporation into clinical trials may improve the ability to compare and evaluate interventions for mucositis.

Feasibility of a symptom management intervention for adolescents recovering from a hematopoietic stem cell transplant

BACKGROUND

Adolescents undergoing a hematopoietic stem cell transplantation (HSCT) experience a variety of adverse effects and eating difficulties. Few interventions exist to assist patients with self-care after HSCT hospitalization. The Eating After Transplant (EAT!) program is a mobile phone applications developed to assist adolescents with self-management of common eating-related issues during HSCT recovery.

OBJECTIVE

This study examined the acceptability and usability of the EAT! program among adolescents and assessed the competency of the participants using the program after hospital discharge through the first 100 days after HSCT.

METHODS

A repeated-measures design was used to evaluate the EAT! application with 16 adolescent patients recovering from an allogeneic HSCT. Participants provided verbal feedback and used a Likert scale to rate acceptability and usability of the application. In addition, a tracking device monitored use of the application. Competency was measured with orientation time and independent demonstration of use of the application.

RESULTS

Acceptability remained high throughout the study, but use significantly decreased over time. Patients reported familiarity with the program's content as the reason for the declining use. Competency was excellent with a short orientation period and independent demonstration throughout the study.

CONCLUSIONS

A mobile phone application is a feasible intervention to educate adolescents with symptom management strategies. Future research needs to examine factors affecting sustainability of use over time.

IMPLICATIONS FOR PRACTICE

Healthcare providers need to continue to develop and evaluate innovative methods to educate adolescents on effective self-care strategies throughout HSCT recovery.

A qualitative review of the psychometric properties and feasibility of electronic headache diaries for children and adults: where we are and where we need to go

BACKGROUND

While paper headache pain diaries have been used to determine the effectiveness of headache treatments in clinical trials, recent advances in information and communication technologies have resulted in the burgeoning use of electronic diaries (e-diaries) for headache pain.

OBJECTIVE

To qualitatively review headache e-diaries, assess their measurement properties, examine measurement components and compare these components with recommended reporting guidelines.

METHODS

The databases Medline, the Cumulative Index to Nursing and Allied Health Literature, Embase, PsychInfo, the Education Resources Information Centre and ISI Web of Science were searched for self-report headache e-diaries for children and adults. A total of 21 publications that involved e-diaries were found; five articles reported on the development of an e-diary and 16 used an e-diary as an outcome measure in randomized controlled trials or observational studies. The diary measures' components, features and psychometric properties, as well as the quality of evidence of their psychometric properties, were evaluated.

RESULTS

Five headache e-diaries met the a priori criteria and were included in the final analysis. None of these e-diaries had well-developed evidence of reliability and validity. Three e-diaries showed evidence of feasibility. E-diaries with ad hoc measures developed by the study investigators were most common, with little to no supportive evidence of reliability and⁄or validity. Compliance with the reporting guidelines was variable, with only one-half of the e-diaries measuring the recommended primary outcome of headache frequency.

CONCLUSIONS

Specific recommendations regarding the development (including essential components) and testing of headache e-diaries are discussed. Further research is needed to strengthen the measurement of headache pain in clinical trials using headache e-diaries.

Initial evaluation of an electronic symptom diary for adolescents with cancer

Background

The delivery of optimal care depends on accurate communication between patients and clinicians regarding untoward symptoms. Documentation of patients’ symptoms necessitates reliance on memory, which is often imprecise. We developed an electronic diary (eDiary) for adolescents and young adults (AYAs) with cancer to record symptoms.

Objective

The purpose of this paper is to describe the utility of an eDiary designed for AYAs with cancer, including dependability of the mobile application, the reasons for any missing recorded data, patients’ adherence rates to daily symptom queries, and patients’ perceptions of the usefulness and acceptability of symptom data collection via mobile phones.

Methods

Our team developed an electronic symptom diary based on interviews conducted with AYAs with cancer and their clinicians. This diary included daily severity ratings of pain, nausea, vomiting, fatigue, and sleep. The occurrence of other selected physical sequelae was assessed daily. Additionally, patients selected descriptors of their mood. A 3-week trial of the eDiary was conducted with 10 AYA cancer patients. Mobile phones with service plans were loaned to patients who were instructed to report their symptoms daily. Patients completed a brief questionnaire and were interviewed to elicit their perceptions of the eDiary and any technical difficulties encountered.

Results

Overall adherence to daily symptom reports exceeded 90%. Young people experienced few technical difficulties and reported benefit from daily symptom reports. Symptom occurrence rates were high and considerable inter- and intra-patient variability was noted in symptom and mood reports.

Conclusions

We demonstrated the utility of an eDiary that may contribute insight into patients’ symptom patterns to promote effective symptom management.

Feasibility of using a handheld electronic device for the collection of patient reported outcomes data from children

The manner in which a communication disorder affects health-related quality of life (QOL) in children is not known. Unfortunately, collection of quality of life data via traditional paper measures is labor intensive and has several other limitations, which hinder the investigation of pediatric quality of life in children. Currently, there is not sufficient research regarding the use of electronic devices to collect pediatric patient reported outcomes in order to address such limitations. Thus, we used a cross-over design to compare responses to a pediatric health quality of life instrument (PedsQL 4.0) delivered using a handheld electronic device to those from a traditional paper form. Respondents were children with (n=9) and without (n=10) a speech or voice disorder. For paper versus the electronic format, we examined time to completion, number of incomplete or inaccurate question responses, intra-rater reliability, ease of use, and child and parent preference. There were no significant differences between children's scores, time to complete the measure, or ratings related to ease of answering questions. The percentage of children who made answering errors or omissions with paper and pencil was significantly greater than the percentage of children who made such errors using the device. This preliminary study demonstrated that use of an electronic device to collect QOL or patient-reported outcomes (PRO) data from children is more efficient than and just as feasible, reliable, and acceptable as using paper forms. The development of hardware and software applications for the collection of QOL and/or PRO data in children with speech disorders is likely warranted.

LEARNING OUTCOMES

The reader will be able to understand: (1) The potential benefits of using electronic data capture via handheld devices for collecting pediatric patient reported outcomes; (2) The Pediatric Quality of Life Inventory 4.0 is a measure of the perception of general health quality that has distinguished between healthy children and those with chronic health conditions; (3) Past research in communication disorders indicates that voice and speech disorders may impact quality of life in children; (4) Based on preliminary data, electronic collection of patient reported outcomes in children with and without speech/voice disorders is more efficient and equally feasible, reliable, and acceptable when compared to paper forms.

Electronic and paper versions of a faces pain intensity scale: concordance and preference in hospitalized children

Background

Assessment of pain in children is an important aspect of pain management and can be performed by observational methods or by self-assessment. The Faces Pain Scale-Revised (FPS-R) is a self-report tool which has strong positive correlations with other well established self-report pain intensity measures. It has been recommended for measuring pain intensity in school-aged children (4 years and older). The objective of this study is to compare the concordance and the preference for two versions, electronic and paper, of the FPS-R, and to determine whether an electronic version of the FPS-R can be used by children aged 4 and older.

Methods

The study is an observational, multicenter, randomized, cross-over, controlled, open trial. Medical and surgical patients in two pediatric hospitals (N = 202, age 4-12 years, mean age 8.3 years, 58% male) provided self-reports of their present pain using the FPS-R on a personal digital assistant (PDA) and on a paper version. Paper and electronic versions of the FPS-R were administered by a nurse in a randomized order: half the patients were given the PDA version first and the other half the paper version first. The time between the administrations was planned to be less than 30 minutes but not simultaneous. Two hundred and thirty-seven patients were enrolled; 35 were excluded from analysis because of misunderstanding of instructions or abnormal time between the two assessments.

Results

Final population for analysis comprised 202 children. The overall weighted Kappa was 0.846 (95%CI: 0.795; 0.896) and the Spearman correlation between scores on the two versions was r_s = 0.911 (p < 0.0001). The mean difference of pain scores was less than 0.1 out of 10, which was neither statistically nor clinically significant; 83.2% of children chose the same face on both versions of the FPS-R. Preference was not modified by order, sex, age, hospitalization unit (medical or surgical units), or previous analgesics. The PDA was preferred by 87.4% of the children who expressed a preference.

Conclusion

The electronic version of the FPS-R can be recommended for use with children aged 4 to 12, either in clinical trials or in hospitals to monitor pain intensity.

Electronic pain assessment in clinical practice

SUMMARY The assessment and treatment of chronic pain remains an international challenge for healthcare providers among aging patients and rising healthcare costs. This article provides a brief overview of studies on the use of electronic pain diaries and innovative software programs for pain assessment and monitoring among providers and persons with chronic pain. The advent of software pain monitoring programs on smart phones, personal digital assistants and internet-based tracking allow for the collection of large datasets of momentary data to better assist in the management of chronic pain. Electronic tracking in the home and clinic can improve data quality and reduce the biases of recalled information compared with paper diaries and questionnaires. Furthermore, 3D pain mapping programs can enable patients to represent the location and intensity of their pain with greater accuracy. However, despite the benefits, there are a number of barriers to incorporating electronic pain assessment into daily clinical practice. Additional control trials and clinical investigations are needed to demonstrate the efficacy and benefit of electronic pain assessment over and above standard practices.

An electronic daily diary process study of stress and health behavior triggers of primary headaches in children

OBJECTIVE

To determine through a daily process study whether alleged psychological and health behavior headache triggers reliably predict headache occurrence in children.

METHODS

Twenty-five children aged 8-17 years with primary headaches reported on their expectancies for headache triggers and then used electronic diaries three times daily for 2 weeks to record headache occurrence, stressors, type and timing of food and drink intake, sleep and wake times, and sleep quality. Hypotheses pertaining to the association of presumed headache triggers and headache occurrence were evaluated using multilevel models.

RESULTS

Only changes in stress level reliably preceded the occurrence of a new headache episode. Nights in which a child had less than his/her typical sleep quantity also tended to predict headache occurrence. Consumption of certain food and drink items was found to be protective.

CONCLUSIONS

Daily stressors seem to be a more reliable trigger of children's headaches than diet or sleep factors.

A graphical vector autoregressive modelling approach to the analysis of electronic diary data

BACKGROUND

In recent years, electronic diaries are increasingly used in medical research and practice to investigate patients' processes and fluctuations in symptoms over time. To model dynamic dependence structures and feedback mechanisms between symptom-relevant variables, a multivariate time series method has to be applied.

METHODS

We propose to analyse the temporal interrelationships among the variables by a structural modelling approach based on graphical vector autoregressive (VAR) models. We give a comprehensive description of the underlying concepts and explain how the dependence structure can be recovered from electronic diary data by a search over suitable constrained (graphical) VAR models.

RESULTS

The graphical VAR approach is applied to the electronic diary data of 35 obese patients with and without binge eating disorder (BED). The dynamic relationships for the two subgroups between eating behaviour, depression, anxiety and eating control are visualized in two path diagrams. Results show that the two subgroups of obese patients with and without BED are distinguishable by the temporal patterns which influence their respective eating behaviours.

CONCLUSION

The use of the graphical VAR approach for the analysis of electronic diary data leads to a deeper insight into patient's dynamics and dependence structures. An increasing use of this modelling approach could lead to a better understanding of complex psychological and physiological mechanisms in different areas of medical care and research.

Children's self-report of pain intensity: what we know, where we are headed

The present paper provides a short, practical introduction to children's self-report measures of pain intensity, followed by an overview of principles and issues. Details on individual self-report scales were previously reported in a landmark systematic review in 2006 and will not be repeated here. Broader measurement issues discussed here include interpretation of pain scores over time, across individuals and in relation to contextual factors; special considerations affecting children younger than six years of age; social communicative functions of pain reports; cognitive developmental factors in understanding pain scales and their anchors; screening for the ability to use self-report scales and training for children who do not have this skill; level of measurement (interval versus ordinal); estimating clinically significant change for groups and individuals; and measurement of aspects of pain other than intensity. Also highlighted are areas in which there has been progress and a lack of progress since the last time this topic was featured at the International Forum on Pediatric Pain in 1996. The present article closes with an outline of key areas for further research on children's self-report of pain and a brief summary of recommendations for clinicians.
