Clinical Meaning of Visual Analog Scales(VAS) for Teenage Pediatric Patients Undergoing Laparoscopic Surgical Procedures

The purpose of this study is to find a more accurate postoperative pain assessment for teenager patients. This is important because a patient should not have a very strong pain medication such as morphine if the pain is just mild.

Pain is a sensory and emotional experience, modified by multiple factors, including meaning, context, previous pain experience, culture, gender, expectation, anxiety, depression, fear, family and social factors. Hospitalized teenager patients (11-18 years) admitted to surgical services experience high prevalence of moderate and severe pain.1 The VAS (Visual Analog Scale, 0 mm "no pain", to 100 mm," the worst pain possible ") is used to assess postoperative pain for teenager patients. The reliability and validity of this scale was proven but clinical significance of VAS pain score is not clear. 2 There is an increased focus on very good pain control and is a common practice that patients with moderate or severe pain scores (numeric rating score, more than 4) to receive opioid pain medication 3, regardless of pain behavior or health care providers' input , and this can result in various side effects. Pediatric nurses administer more pain medications to the children who vocalize their pain. 4 Numerous clinical trials of postoperative pain treatment in teenager use only VAS pain scores to assess the effectiveness of a studied pain medication.

Although the treatment of pain may be a basic human right, that does not mean that all teenager patients require opioids administration if they report high pain scores. It is our observation that teenager's pain behavior does not always correlate with the magnitude of reported pain scores by the patient and different caregivers. Concomitant parental and nurse observation of teenager's pain behavior can provide additional information about pain severity. Minimal correlation between VAS pain scores reported by teenager and caregivers does not mean that pain severity is "unreal". Perioperative teenager's pain catastrophizing thoughts about pain, anxiety, and mood level can influence teenager's postoperative pain scores.

The authors aim is to develop a multi-modal assessment of postoperative pain for the teenager patient, using VAS pain scores reported by the teenager, nurse, and parent in association with the teenager's postoperative pain behavior, pain catastrophizing thinking, anxiety, and mood level. The subjects included in this study will be 206 teenager patients (11-17 years old) undergoing any laparoscopic surgical procedures. On postoperative day 1, the teenager will complete the following questionnaires: Visual Analog Scale from teenager (VAS teen), State-Trait Anxiety Inventory for Children (STAIC S - Anxiety), Pain Catastrophizing Scale for Children (PCS-C) and Brief Mood Introspection Scale (BMIS). The nurse taking care of the patient and one parent, preferable the mother, will complete the following questionnaires: Visual Analog Scale from parent (VAS p), Visual Analog Scale from nurse (VAS n), and Adolescent Pain Behavior Questionnaire from parent (APBQ-p), Adolescent Pain Behavior Questionnaire from nurse (APBQ-n). The main goal is to determine if VAS score reported by the teenager correlates with VAS scores reported by the parent and nurse, and with pain behavior scores reported by the nurse and family. Expected correlation is minimal (0.23-0.29) to moderate (0.3-0.49). Our second goal is to determine whether postoperative pain is associated with psychosocial factors such as teenager catastrophizing attention to pain, anxiety, and mood level. Expected correlation between postoperative VAS teen and teenager catastrophizing attention to pain, anxiety, and mood level is moderate (0.3-0.49) to high (\>/=0.5).

To our knowledge, this is the first study to investigate all these variables together to assess postoperative pain for a teenager patient. The findings of this study may influence the medical decisions regarding administration of pain medication, allow for a safer and more effective use of opioids in postoperative period and would be very helpful for clinical and research practice.
