Pain in young children with burns: extent, course and influencing factors.

Little evidence is available on the extent, course and influencing factors of pain in young children with burns. At present, reliable and valid measurement instruments to assess pain behavior in these children are available, implying that valuable insight into these questions can now be obtained. The aim of this study is to document the extent and course of pain behavior with the COMFORT-B, and to assess factors that may influence procedural pain. First, cutpoints for COMFORT-B scores were established by Rasch analysis to assess clinically relevant changes. Second, the extent of background and procedural pain behavior was assessed by descriptive statistics. Third, the course and factors that may influence procedural pain behavior were investigated by latent growth modeling. Trained nurses collected pain behavior data in 168 children (mean age 20 months, mean TBSA 6%, mean length of stay 10 days). Cutpoints of COMFORT-B scores were as follows: 6-13 (mild pain), 14-20 (moderate pain) and 21-30 (severe pain). This study suggests that background pain is more adequately treated than procedural pain. Factors that influenced baseline pain scores and/or the course over 8 days included TBSA, the number of surgical procedures, acetaminophen administration by the referring hospital, and the application of hydrofiber dressings. The implications of these findings are discussed.

The implementation and evaluation of therapeutic touch in burn patients: an instructive experience of conducting a scientific study within a non-academic nursing setting.

OBJECTIVE: Evaluation of therapeutic touch (TT) in the nursing of burn patients; post hoc evaluation of the research process in a non-academic nursing setting. METHODS: 38 burn patients received either TT or nursing presence. On admission, days 2, 5 and 10 of hospitalization, data were collected on anxiety for pain, salivary cortisol, and pain medication. Interviews with nurses were held concerning research in a non-academic setting. RESULTS: Anxiety for pain was more reduced on day 10 in the TT-group. The TT-group was prescribed less morphine on day 1 and 2. On day 2 cortisol level before dressing changes was higher in the TT-group. The situational challenges of this study led to inconsistencies in data collection and a high patient attrition rate, weakening its statistical power. CONCLUSION: Conducting an effect study within daily nursing practice should not be done with a nursing staff inexperienced in research. Analysis of the remaining data justifies further research on TT for burn patients with pain, anxiety for pain, and cortisol levels as outcomes. PRACTICE IMPLICATIONS: Administering and evaluating TT during daily care requires nurses experienced both in TT and research, thus leading to less attrition and missing data, increasing the power of future studies.

Construct validity of two pain behaviour observation measurement instruments for young children with burns by Rasch analysis.

In this study, construct validity of 2 pain behaviour observation measurement instruments for young children aged 1 to 56 months (mean age was 20 months) with burns is assessed by using Rasch analysis. The Rasch model, wherein data should meet the model expectations, assumes that an instrument measures one unidimensional construct, and focuses on the items of measurement instruments. The Pain Observation Scale for Young Children (POCIS) and the COMFORT Behaviour Scale (COMFORT-B) measure background and procedural pain as unidimensional. Adequate measurements for scientific research and daily practice can now be obtained.

Reliability, validity and clinical utility of three types of pain behavioural observation scales for young children with burns aged 0-5 years.

Pain measurement is a prerequisite for individualized pain management and research into pain interventions. There is a need for reliable and valid pain measures for young children with burns. The aim of this study was to investigate whether the pain observation scale for young children (POCIS), the COMFORT behaviour scale (COMFORT-B) and the nurse observational visual analogue scale (VAS obs) are reliable, valid and clinically useful instruments to measure pain in children with burns aged 0-5years. Participating trained nurses (N=102) rated pain of 154 children during hospitalization. Two trained nurses simultaneously assessed pain at fixed intervals by using the previous mentioned measures. Cronbach's alpha for POCIS was .87 for background and .89 for procedural pain. Intraclass Correlation Coefficients (ICCs) were .75 for background and .81 for procedural pain. COMFORT-B observations yielded Cronbach's alpha of .77 for background and .86 for procedural pain and ICCs of .83 for background and .82 for procedural pain. The VAS obs resulted in ICCs of .55 for background and .60 for procedural pain. Correlation coefficient between POCIS and COMFORT-B was .79 (p<.01), Standardized response mean was 1.04 for both POCIS and COMFORT-B. Background pain measured with POCIS and COMFORT-B was lower than procedural pain (p<.001). Nurses found POCIS easier and quicker to use, but COMFORT-B was found to indicate pain more accurately. Both POCIS and COMFORT-B are reliable, valid and practical scales for pain measurement in young children with burns and can be used in practice and research. The VAS obs was found to be unreliable.
