Patient Controlled Analgesia for Vaso-Occlusive Episodes in Children: A Retrospective Study.

OBJECTIVE: To describe Patient-Controlled Analgesia (PCA) administration in pediatric patients admitted with sickle cell vaso-occlusive episode (VOE). METHODS: This single-center retrospective study included all inpatient hematology admissions for VOE between 2014 and 2020. PCA-ratio was calculated as the ratio of bolus over continuous IV opioids dose, and time to PCA adjustment as time between first PCA order and a subsequent order that increased dosing or changed opioid medication. RESULTS: A total of 866 encounters (172 unique patients) with PCA for VOE were included. The mean age was 15.4 years old (SD = 5.0). On average, after admission (hospital arrival), the first opioid dose was given at 1 hour, PCA started at 3.5 hours, and mean length of stay was 4.3 days (SD = 2.5). The mean initial PCA-ratio was 1.7 (SD = 0.6). There were no significant associations between age, gender, initial pain score, or admission hemoglobin and PCA-ratio (linear regression model P = 0.443). In 24.7% of encounters, the PCA was adjusted within 6 hours. After adjusting by age and gender, lower admission pain scores (OR = 1.15, P = 0.004), lower PCA-ratio (OR = 2.1, P = 0.003), longer time to PCA start (OR = 1.2, P = 0.001), and no adjuvant ketamine (OR = 2.4, P < 0.001) were associated with PCA unadjusted within 6 hours. CONCLUSION: At our institution, patients with VOE received opioids and PCA within the first hours of admission. PCAs were started at a ratio of 1.5-1.8, considered normal continuous. While no specific PCA-ratio was clearly superior for pain control, lower ratios (high continuous infusion) were associated with not requiring PCA adjustments at 6 hours. Prospective studies are needed.

Standardizing Opioid Prescribing in a Pediatric Hospital: A Quality Improvement Effort.

BACKGROUND: Opioids are indicated for moderate-to-severe pain caused by trauma, ischemia, surgery, cancer and sickle cell disease, and vaso-occlusive episodes (SCD-VOC). There is only limited evidence regarding the appropriate number of doses to prescribe for specific indications. Therefore, we developed and implemented an opioid prescribing algorithm with dosing guidelines for specific procedures and conditions. We aimed to reach and sustain 90% compliance within 1 year of implementation. METHODS: We conducted this quality improvement effort at a pediatric academic quaternary care institution. In 2018, a multidisciplinary team identified the need for a standard approach to opioid prescribing. The algorithm guides prescribers to evaluate the medical history, physical examination, red flags, pain type, and to initiate opioid-sparing interventions before prescribing opioids. Opioid prescriptions written between January 2015 and September 2020 were included. Examples from 2 hospital departments will be highlighted. Control charts for compliance with guidelines and variability in the doses prescribed are presented for selected procedures and conditions. RESULTS: Over 5 years, 83 037 opioid prescriptions in 53 804 unique patients were entered electronically. The encounters with ≥1 opioid prescription decreased from 48% to 25% between 2015 and 2019. Compliance with the specific guidelines increased to ∼85% for periacetabular osteotomies and SCD-VOC and close to 100% for anterior-cruciate ligament surgery. In all 3 procedures and conditions, variability in the number of doses prescribed decreased significantly. CONCLUSION: We developed an algorithm, guidelines, and a process for improvement. The number of opioid prescriptions and variability in opioid prescribing decreased. Future evaluation of specific initiatives within departments is needed.

Initial Validation of GRASP: A Differential Diagnoses Algorithm for Children With Medical Complexity and an Unknown Source of Pain.

OBJECTIVES: Identifying the source of pain for children with medical complexity (MC) is challenging. The purpose of this study was the initial validation of a tool to guide the medical evaluation for identifying the source of pain in children with MC by using differential diagnoses. The tool is entitled Guidelines for Ruling Out and Assessing Source of Pain (GRASP). METHODS: A mixed-methods approach that included expert review, focus groups, Web-based surveys, and a trial of the GRASP was used to determine validity as well as perceived clinical utility. RESULTS: Focus groups were held with 26 inpatient and outpatient clinicians. Participants consistently responded in support of the GRASP. Participants advised several suggestions for tool organization such as designing the tool as a flow diagram. Seven clinicians participated in Web-based surveys and made specific suggestions for making the GRASP more comprehensive. Six participants trialed the GRASP for 14 children with MC and pain of unknown origin. Overall, participants found that the GRASP was a clinically effective tool for guiding medical evaluation. CONCLUSIONS: These results provide preliminary evidence that the GRASP has content and face validity in evaluating the source of pain in children with MC. This tool can be used to systematically guide clinicians through a balanced approach to evaluation with a goal of determining the pain source, preventing harm, and relieving suffering without unnecessary tests.

Effect of a Sedation Weaning Protocol on Safety and Medication Use among Hospitalized Children Post Critical Illness.

BACKGROUND: Best practice guidelines for the safe and compassionate care of critically ill children necessitates the use of sedation to ensure adequate ventilation, patient safety and comfort. Prolonged use of sedation can result in tolerance, physical dependence and iatrogenic withdrawal syndrome if medications are weaned too quickly. PROBLEM: In the context of medication errors related to parent administration of outpatient sedation weans, we set out to improve the safety of children weaning from sedatives. METHODS: A retrospective analysis was completed. Quality improvement was guided by using Plan-Do-Study-Act cycles. INTERVENTIONS: An evidence-based post PICU sedation weaning guideline was created and implemented over time with ongoing education, and review of progress with staff members with pre-post evaluation. RESULTS: Post intervention, there were significant differences in the numbers of patients discharged on home weaning from both opioids and benzodiazepines (11%, n = 24/219 pre; 3%, n = 7/233 post; p < 0.005). The number of patients discharged with a methadone wean decreased (7%, n = 16/219 pre; 0%, 0/233 post; p = 0.03). Despite these differences, there were no significant differences in the median hospital length of stay (42 pre; 39 post; p = 0.35). Post implementation more children had mild to moderate symptoms of withdrawal (11% pre; 21% post; p < 0.005) as compared to pre-implementation, however, the percentage of severe symptoms remained consistently low (0.6% pre; 1% post; p = 0.11). CONCLUSIONS: Implementation of an evidence-based post PICU weaning guideline significantly reduced the number of patients discharged on potentially dangerous medications with modest increases in mild-moderate symptoms of withdrawal and no significant change in length of stay or the incidence of severe symptoms of withdrawal.

An update on complex regional pain syndromes in children and adolescents.

PURPOSE OF REVIEW: Complex regional pain syndrome (CRPS) is a chronic pain condition typically involving a limb, which is characterized by neuropathic pain, sensory abnormalities and neurovascular findings. The exact cause of CRPS is unknown; however, proposed theories include alterations in the sympathetic and central nervous system (CNS), small fibre changes in the peripheral nervous system and psychological factors. Although this condition was previously considered rare among children and adolescents, it has been increasingly recognized in paediatric patients and can result in significant disability. RECENT FINDINGS: The diagnosis of paediatric CRPS is based upon clinical criteria obtained from a thorough history and physical examination. Other possible causes, such as orthopaedic, infectious, vascular and rheumatologic disorders, should be ruled out prior to making the diagnosis. Treatment focuses on a rehabilitative strategy consisting of physical therapy, occupational therapy and cognitive-behavioural therapy with an overall focus on return to functioning. SUMMARY: CRPS in children and adolescents is characterized by a painful, mottled appearing, swollen limb with allodynia and hyperalgesia. For most patients, pain is severe, resulting in significant functional disability. More recent evidence suggests that a rehabilitative programme results in improvement in both pain and functional measures.

Management of adolescent chronic pelvic pain from endometriosis: a pain center perspective.

OBJECTIVES: To review the options for the treatment of chronic pelvic pain in adolescents with endometriosis. METHODS: Review of publications and description of author's experience relating to adolescent endometriosis and pain treatment. RESULTS: Pain treatment services offer a multidisciplinary approach for the treatment of chronic pelvic pain consisting of analgesic trials, cognitive-behavioral therapy, physical therapy, and complementary and alternative therapies. Patients are also evaluated for other conditions that might contribute to their chronic pain. Medication trials of antidepressants, anticonvulsants, tramadol, and nonsteroidal anti-inflammatory drugs are frequently used; however, there are limited data on efficacy. Biobehavioral techniques such as relaxation and biofeedback can help patients modify their experience of pain. Cognitive behavioral therapy can improve coping skills and promote improved functioning, particularly in patients who are debilitated from chronic pain. Transcutaneous electrical stimulation (TENS) and physical therapy approaches may be helpful in patients with musculoskeletal conditions that contribute to their pelvic pain. Complementary and alternative therapies are frequently used in the treatment of chronic pain; controlled trials are needed to assess efficacy. CONCLUSIONS: An individualized, multidisciplinary approach may be effective in improving overall outcome in patients with chronic pelvic pain in reducing pain and normalizing function.
