Parents' pain medication underdosing is associated with more emergency department visits in sickle cell disease.

OBJECTIVE: To determine the association between health literacy, medication knowledge, and pain treatment skills with emergency department (ED) use of parents of children with sickle cell disease (SCD). METHODS: Parents of children 1- to 12-years-old with SCD were enrolled. Health literacy was assessed using the Newest Vital Sign. Parents completed a structured interview assessing knowledge of the dosage and frequency of home pain medications and an applied skills task requiring them to dose a prescribed pain medication. Underdosage was defined by too small a dose (dosage error) or too infrequent a dose (frequency error). The association between medication knowledge and applied skills with ED visits for pain over the past year was evaluated using Poisson regression adjusting for genotype. RESULTS: One hundred parent/child pairs were included; 50% of parents had low health literacy. Low health literacy was associated with more underdose frequency errors (38% vs. 19%, P = 0.02) on the skills task. On medication knowledge, underdose dosage errors (adjusted incidence rate ratio [aIRR] 2.0, 95% confidence interval [CI] 1.3-3.0) and underdose frequency errors (aIRR, 1.7, 95% CI 1.2-2.6) were associated with a higher rate of ED visits for pain. On the skills task, underdose dosage errors (aIRR 1.6, 95% CI 1.1-2-.4) and underdose frequency errors were associated with more ED visits (aIRR 1.5, 95% CI 1.1-2.1). CONCLUSIONS: For medication knowledge and skills tasks, children of parents who underdosed pain medication had a higher rate of ED visits for pain. Health literate strategies to improve parents' medication skills may improve pain treatment at home and decrease healthcare utilization.

A Comparison of Pain Assessment Measures in Pediatric Sickle Cell Disease: Visual Analog Scale Versus Numeric Rating Scale.

Given the availability of various pain severity scales, greater understanding of the agreement between pain scales is warranted. We compared Visual Analog Scale (VAS) and Numeric Rating Scale (NRS) pain severity ratings in children with sickle cell disease (SCD) to identify the relationship and agreement between pain scale ratings. Twenty-eight patients (mean ± SD age, 14.65 ± 3.12 y, 50% female) receiving pain interventions within the emergency department completed serial VAS and NRS pain severity ratings every 30 minutes. Data were used to calculate the relationship (Spearman correlation) and agreement (Bland-Altman approach) between the VAS and NRS. One hundred twenty-eight paired VAS-NRS measurements were obtained. VAS and NRS ratings were significantly correlated for the initial assessment (rs = 0.88, P < 0.001) and all assessments (rs = 0.87, P < 0.001). Differences between VAS and NRS means were -0.52 (P = 0.006) for the initial assessment and -0.86 (P < 0.001) across all assessments. The difference between VAS and NRS ratings decreased as pain severity increased across all assessments (P = 0.027), but not the initial assessment. Within pediatric patients with SCD, VAS and NRS ratings were found to trend together; however, VAS scores were found to be significantly lower than NRS scores across assessments. The agreement between the 2 measures improved at increasing levels of pain severity. These findings demonstrate that the VAS and NRS are similar, but cannot be used interchangeably when assessing self-reported pain in SCD.

Mental health disorders influence admission rates for pain in children with sickle cell disease.

BACKGROUND: Patients with sickle cell disease (SCD) experience a broad range of mental health disorders placing them at risk for more complicated hospitalizations for pain. The current study examined the impact of mental health disorders on admission rates and hospital length of stay (LOS) for vaso-occlusive pain events (VOE) in pediatric patients with SCD. PROCEDURE: Patients (5-18 years old) with a primary discharge diagnosis of SCD with crisis were acquired through the Pediatric Health Information System and categorized by history of mental health disorders (mood disorder, anxiety disorder, disruptive behavior disorder, and substance use disorder). Using a retrospective cohort design, hospital admission rates for VOE were examined as the primary outcome and LOS as a secondary outcome. RESULTS: A total of 5,825 patients accounted for 23,561 admissions for SCD with crisis with approximately 8% of the patients having a mental health diagnosis. Longer LOS was found among patients with a history of any mental health diagnosis (P < 0.0001) and within the mood disorder (P < 0.0001), anxiety disorder (P < 0.0001), and substance use disorder (P = 0.01) subtypes. Hospital admissions rates for VOE were higher among patients with a history of any mental health diagnosis (P < 0.0001) and within the mood disorder (P < 0.0001), anxiety disorder (P < 0.0001), disruptive behavior disorder (P = 0.002), and substance use disorder (P < 0.0001) subtypes. CONCLUSIONS: Pediatric patients with SCD and a history of a mental health diagnosis have longer LOS and higher admission rates for management of VOE. Ultimately, these findings suggest that mental health pose a challenge to the management of sickle cell pain.

Clinically meaningful measurement of pain in children with sickle cell disease.

BACKGROUND: Limited understanding of the interpretability of patient-reported pain scores may impact pain management. The current study assessed the minimal clinically significant improvement in pain and pain scores signifying patient-reported need for medication and treatment satisfaction in patients with sickle cell disease (SCD). PROCEDURE: Patients, 8-18-years-old, with SCD were recruited while receiving treatment for pain. Patients completed initial pain severity ratings using the Visual Analog Scale (VAS) and the Numeric Rating Scale (NRS). Serial assessments of pain severity, pain relief, perceived need for medication, and treatment satisfaction were completed in the emergency department and the hospitalization. Data were used to calculate the minimal clinically significant improvement in pain and pain scores associated with perceived need for pain medication and treatment satisfaction. RESULTS: Twenty-eight patients completed 305 assessments during 37 total visits. A decrease in pain severity score of 0.97 cm for the VAS and 0.9 for the NRS was found to be the minimum clinically significant improvement in pain. Pain scores >7.45 cm on the VAS or 7.5 on the NRS were suggestive of patient-reported need for pain medication. Pain scores <7.35 cm on the VAS or 8.5 on the NRS were suggestive of patient-reported treatment satisfaction discrimination. CONCLUSIONS: The minimal clinical significant improvement was defined for the VAS and NRS and both scales were able to discriminate between important clinical findings including pain relief, need for pain medication, and treatment satisfaction. Collectively, this study provides data to improve our understanding of pain ratings of pediatric patients with SCD.

Impact of psychiatric diagnoses on hospital length of stay in children with sickle cell anemia.

BACKGROUND: Patients with sickle cell anemia (SCA) experience a broad range of psychiatric disorders, placing them at risk for more complicated and longer hospitalizations for vaso-occlusive crises (VOC). The current study examined the frequency of psychiatric disorders in SCA patients (ages birth to 20 years) admitted for VOC in a nationally representative sample and the association between psychiatric disorders and hospital length of stay (LOS). PROCEDURE: Patients with a primary diagnosis of SCA with crisis identified through the nationally representative Kids' Inpatient Database (KID) 2006 from the Agency of Healthcare Research and Quality were included for analysis. Patients with psychiatric disorders listed as secondary diagnoses were categorized under specific psychiatric disorders (mood disorder, anxiety disorder, disruptive behavior disorder, substance use disorder). Non-parametric and regression analyses were utilized for nationally weighted data, to determine the effect of psychiatric disorders on LOS, while controlling for significant covariates. RESULTS: For 21,255 hospital discharges for children with SCA with crisis in 2006, the mean LOS was 4.51 days. Approximately 6% of the patients discharged had a psychiatric disorder. After adjusting for significant covariates, mood disorders, anxiety disorders, and any psychiatric disorder were each associated with significantly longer LOS (P < 0.01). Substance and disruptive behavior disorders were not associated with LOS. CONCLUSIONS: Pediatric patients diagnosed with a psychiatric disorder, specifically mood or anxiety disorders, have longer LOS for VOC. These findings suggest that future interventions aimed at managing VOC may need to consider adjunctive psychiatric assessment and intervention.

Single-session biofeedback-assisted relaxation training in children with sickle cell disease.

Sickle cell disease (SCD) pain remains difficult to manage. This pilot study evaluated single-session biofeedback-assisted relaxation training (BART) for SCD pain in children. Ten participants (mean = 12.1 y) completed a 1-hour BART session using thermal biofeedback and home practice. Participants demonstrated changes in peripheral body temperature after the training session (d = 1.08) and at 6-week follow-up (d = 0.97) relative to their baseline visit. Reductions in patient-reported pain frequency were found after completing BART. Health-related quality of life and pain-related disability improvements were observed; however, effect sizes were small to minimal. Single-session BART may be a promising, complementary approach to medical management of pediatric SCD pain.

The relationship between parent health literacy and pediatric emergency department utilization: a systematic review.

BACKGROUND: Low health literacy in parents can potentially impact understanding of a child's diagnosis and treatment course. No reviews have addressed parent health literacy in the emergency department (ED), the relationship between parent health literacy and child ED utilization, or the impact of low literacy interventions on child ED utilization. OBJECTIVE: To systematically evaluate the peer-reviewed literature pertaining to parental health literacy and ED utilization. The following key questions were addressed: question (Q) 1) What is the prevalence of low health literacy, as estimated by validated health literacy measures, of parents in the ED? Q2) Is parent low health literacy related to ED use for children? Q3) Do low literacy interventions targeting parents likely to have low health literacy affect ED use for children? DATA SOURCES: The authors reviewed 483 unduplicated titles and abstracts published between 1980 and May 2012 using PubMed and CINAHL, with 117 retained for full review and 17 included in the final analytic review. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS: All included articles had a valid measure of parent health literacy and a Q1) descriptive measurement of the population, Q2) ED utilization, or Q3) utilized a low literacy educational intervention. STUDY APPRAISAL AND SYNTHESIS METHODS: One author extracted data verified by a second author. Studies were rated for quality by both authors. RESULTS: Q1) A median of 30% (interquartile range 22-36%) of parents in the ED possesses low health literacy. Q2) Studies investigating the relationship between health literacy and ED yielded mixed results. Q3) Seven of 8 low literacy interventions were associated with a reduction in ED use. Random effects pooled odds ratios from 6 studies showed intervention effectiveness (odds ratio 0.35; 95% CI 0.15-0.81). LIMITATIONS: No intervention studies measured health literacy, limiting the ability to determine whether the low literacy intervention targeted health literacy. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: Roughly 1 in 3 parents of children presenting to the ED have low health literacy. Importantly, interventions targeting parents likely to have low health literacy have an impact in reducing ED utilization.

Academic attainment findings in children with sickle cell disease.

BACKGROUND: Children with sickle cell disease (SCD) demonstrate deficits in cognitive and academic functioning. This study compared the academic attainment of children with SCD relative to national, state, and local school district rates for African American students. METHODS: A retrospective chart review of children with SCD was completed and academic information was collected from caregiver report and school records. One-sample tests of proportions were calculated to compare academic attainment rates in children with SCD relative to national, state, and local school district normative data of African American students. RESULTS: Overall, 197 patient records were reviewed. A higher proportion of children with SCD were retained a grade relative to national, state, and local school district rates for African American students. In addition, a higher proportion of children with SCD received special education services relative to the national, state, and local school district rates for African American students. CONCLUSION: Children with SCD demonstrate higher rates of special education services and grade retention relative to African American peers. Overall, children with SCD demonstrate poorer academic attainment relative to healthy, African American peers highlighting the need for increased focus on special education services to address school performance issues within this population.
