  • Evaluation of Toothache Severity in Children Using a Visual Analogue
    Scientific Article Evaluation of Toothache Severity in Children Using a Visual Analogue Scale of Faces Eliane de Paula Reis Barrêtto, BDS, MSc Efigênia Ferreira e Ferreira, BDS, PhD Isabela Almeida Pordeus, BDS, PhD Dr. Barrêtto is pediatric clinician, pediatric dentistry, and Drs. Ferreira and Pordeus are senior lecturers, Dental School, Federal University of Minas Gerais (FO-UFMG), Minas Gerais, Brazil. Correspond with Dr. Barrêtto at [email protected] Abstract Purpose: Pain is a frequent symptom of oral disease. It is difficult to measure, however, due to its subjectivity, especially among children. The purpose of this study was to verify the utility and applicability of a visual analogue scale of faces (VASOF), adapted for 8- to 9-year-olds, to measure the severity of toothaches. Methods: A cross-sectional study was undertaken, which included 601 boys and girls ran- domly selected from state and private schools in the city of Belo Horizonte, Minas Gerais, Brazil. They were interviewed and clinically examined, and a VASOF was applied. Results: The VASOF’s application revealed a high percentage of intense/very intense pain in the sample (39%). The presence of this pain intensity was accompanied by a high incidence of children who cried, were awakened by the pain, and were unable to carry out habitual tasks. Furthermore, this severe pain was strongly associated with less- privileged economic groups and the presence of oral pathology (P≤.05). The scale was well understood by children, independent of gender or economic group. Conclusions: A VASOF was found to be capable of measuring toothache severity expe- rienced by school-age children.

    2 Assessment and measurement of pain and pain treatment Section Editor: Prof David A Scott 2 2.1 | Assessment Contributors: Prof David A Scott, Dr Andrew Stewart 2.2 | Measurement Contributors: Prof David A Scott, Dr Andrew Stewart 2.3 | Outcome measures in acute pain management Contributors: Prof David A Scott, Dr Andrew Stewart 5th Edition | Acute Pain Management: Scientific Evidence 3 2.0 | Assessment and measurement of pain and pain treatment Reliable and accurate assessment of acute pain is necessary to ensure safe and effective pain management and to provide effective research outcome data. The assessment and measurement of pain is fundamental to the process of assisting in the diagnosis of the cause of a patient’s pain, selecting an appropriate analgesic therapy and evaluating then modifying that therapy according to the individual patient’s response. Pain should be assessed within a sociopsychobiomedical model that recognises that physiological, psychological and environmental factors influence the overall pain experience. Likewise, the decision regarding the appropriate intervention following assessment needs to be made with regard to a number of factors, including recent therapy, potential risks and side effects, any management plan for the particular patient and the patient’s own preferences. A given pain ‘rating’ should not automatically trigger a specific intervention without such considerations being undertaken (van Dijk 2012a Level IV, n=2,674; van Dijk 2012b Level IV, n=10,434). Care must be undertaken with pain assessment to avoid the process of assessment itself acting as a nocebo (see Section 1.3). 2.1 | Assessment The assessment of acute pain should include a thorough general medical history and physical examination, a specific “pain history” (see Table 2.1) and an evaluation of associated functional impairment (see Section 2.3).

Three studies were carried out to revise the original scale and validate the adapted version. In the ®rst phase, the FPS was revised from its original seven faces to six, while maintaining its desirable psychometric properties, in order to make it compatible in scoring with other self-rating and observational scales which use a common metric (0±5 or 0±10). Using a computer-animated version of the FPS developed by Champion and colleagues (Sydney Animated Facial Expressions Scale), psychophysical methods were applied to identify four faces representing equal intervals between the scale values representing least pain and most pain. In the second phase, children used the new six-face Faces Pain Scale ± Revised (FPS-R) to rate the intensity of pain from ear piercing. Its validity is supported by a strong positive correlation (r 0:93, N 76) with a visual analogue scale (VAS) measure in children aged 5±12 years. In the third phase, a clinical sample of pediatric inpatients aged 4± 12 years used the FPS-R and a VAS or the colored analogue scale (CAS) to rate pain during hospitalization for surgical and non-surgical painful conditions.

  • Pain Assessment and Documentation (Adult)
    Department: PATIENT CARE Policy/Procedure: PAIN ASSESSMENT AND DOCUMENTATION (ADULT) Refer to policy MC.E.48 for neonatal to pediatric pain assessment and management. Definition: Pain can be described as an unpleasant sensory or emotional experience associated with actual and potential tissue damage, disease, trauma, surgery or certain therapeutic procedures. Policy: 1. Patients and their families shall be educated and informed that pain management is an important part of their care. Education should include pain assessment process, pain plan of care, and the importance of effective pain management 2. Each patient shall have the right to pain management through assessment, intervention and reassessment. Each patient has the right to expect his/her report of pain to be accepted, to have the pain assessed and reassessed, to have interventions provided and to achieve and maintain an optimal level of pain relief. The patient's self-report will be the primary means to determining pain. Torrance Memorial Medical Center (TMMC) employees shall assess and report the patients' pain across the continuum and intervene, as appropriate. 3. Ability to understand pain shall be assessed using an age or condition specific assessment tool. See Appendix B and C. 4. Pain assessments: a. A comprehensive pain assessment will be performed during the admission process and will include: a physical examination, patient’s acceptable level of pain, pain history (including acute and chronic pain identification and assessment), medication, and non-medication pain interventions used at home or in the past. b. A routine pain assessment will include time, intensity of pain (level of pain) or behavior scale score, quality of pain (pain type) and location.

  • 0-10 Pain Scale Complaints for Head Injured and Orthopedic Patients
    Paper Presentation to the American Psychological Association 2000 National Convention 0-10 Pain Scale Complaints For Head Injured And Orthopedic Patients Daniel Bruns, PsyD Health Psychology Associates Greeley, Colorado www.healthpsych.com and John Mark Disorbio, EdD Integrated Therapies Lakewood, Colorado 2 0-10 Pain Scale Complaints for Head Injured and Orthopedic Patients Introduction Measures of patient’s pain complaints have been developed and used in clinical studies and research for decades (Gatchel & Turk, 1999). However, it has been noted that there has been little normative information available for such instruments (Turk & Melzack, 1992). They note that: The appropriateness of norms of tests has rarely been considered in the pain literature. In the absence of normative information, the raw score on any test is meaningless. To observe that a patient with a migraine headache scores a 10 on a Visual Analog Scale (VAS) of intensity conveys little or no information. However, if it is known that the average pain severity for 100 migraine headache patients is 5.4 with a standard deviation of 1.0, this information would permit the conclusion that this patient is expressing a very high level of pain relative to other migraine sufferers. Turk and Melzack go on to state that general medical norms are not helpful. They noted that it would be of little value to compare the pain level of a migraine sufferer to the average pain level of cancer patients. This is, in effect, comparing apples with oranges. Such norms would be of no benefit in determining whether or not a particular migraine sufferer’s headache complaints were unusual.

This can be treated by using dry needling and friction massage. Objective. This study aims to determine the effectivity of dry needling and friction massage to improve pain in upper trapezius myalgia patients. Method. The study was conducted at Inco Hospital, Sorowako, South Sulawesi, Indonesia, involving 20 subject who meet the inclusion and exclusion criteria of having upper trapezius myalgia and 20 – 65 years old. Pain was measured using NPRS at baseline and after 3 times therapy for 5 weeks. Result. At the end of therapy (3 times), both of groups showed decrease of pain scale compared to baseline.

  • Pain: the Fifth Vital Sign.” 17
    1 In 2001, as part of a national effort to address the widespread problem of underassessment and undertreatment of pain, The Joint Commission (formerly The Joint Commission on the Accreditation of Healthcare Organizations or JCAHO) introduced standards for organizations to improve their care for patients with pain.1 For over a decade, experts had called for better assessment and more aggressive treatment, including the use of opioids.2 Many doctors were afraid to prescribe opioids despite a widely cited article suggesting that addiction was rare when opioids were used for short-term pain.3 Education, guidelines, and advocacy had not changed practice, and leaders called for stronger methods to address the problem.4-7 The standards were based on the available evidence and the strong consensus opinions of experts in the field. After initial accolades and small studies showing the benefits of following the standards, reports began to emerge about adverse events from overly aggressive treatment, particularly respiratory depression after receiving opioids. A report from The Institute for Safe Medication Practices (ISMP) asked, “Has safety been compromised in our noble efforts to alleviate pain?”8 In response to these unintended consequences, the standards and related materials were quickly changed to address some of the problems that had arisen. But lingering criticisms of the standards continue to this day, often based on misperceptions of what the current standards actually say. This article reviews the history of The Joint Commission standards, the changes that were made over time to try to maintain the positive effects they had on pain assessment and management while mitigating the unintended consequences, and recent efforts to update the standards and add new standards to address today’s opioid epidemic in the United States.
