ABSTRACT

Failure to complete subspecialty referrals decreases access to subspecialty care and may endanger patient safety. We conducted a retrospective analysis of new patient referrals made to the 14 most common referral departments at Boston Children's Hospital from January 1 to December 31, 2017. The sample included 2031 patient referrals. The mean wait time between referral and appointment date was 39.6 days. In all, 87% of referrals were scheduled and 84% of scheduled appointments attended, thus 73% of the original referrals were completed. In multivariate analysis, younger age, medical complexity, being a non-English speaker, and referral to a surgical subspecialty were associated with a higher likelihood of referral completion. Black and Hispanic/Latino race/ethnicity, living in a Census tract with Social Vulnerability Index (SVI) ≥ 90th percentile, and longer wait times were associated with a lower likelihood of appointment attendance. Future interventions should consider both health care system factors such as appointment wait times and community-level barriers to referral completion.

ABSTRACT

OBJECTIVE: To evaluate the effect of the COVID-19 pandemic on childhood lead testing and blood lead levels. METHODS: A retrospective analysis of lead tests and results was performed across 3 urban medical centers during the pre-COVID-19 (March 10, 2019-March 9, 2020) and COVID-19 (March 10, 2020-March 10, 2022) periods. Interrupted time series analysis with quasi-Poisson regression was used to evaluate changes in lead testing between study periods. The relationship between sociodemographic features with detectable (≧2 µg/dL) and elevated (≧3.5 µg/dL) blood lead levels (BLLs) was assessed with multivariable logistic regression. RESULTS: Among a total of 16,364 lead tests across 10,362 patients, weekly testing rates significantly decreased during COVID-19 (relative risk (RR) 0.64, 95% (confidence interval) CI 0.53-0.78). Census tracts with the greatest proportion of pre-1950s housing had a stronger association with detectable BLLs during the COVID-19 period (pre-COVID-19 adjusted odds ratio (aOR) 1.73, 95% CI 1.35-2.20; aOR 2.58, 95% CI 2.13-3.12; interaction P value .014). When limited to 1 year following COVID-19 (March 10, 2020-March 10, 2021), the association between both elevated BLLs (pre-COVID-19: aOR 1.49, 95% CI 0.87-2.53; COVID-19: aOR 3.51, 95% CI 1.98-6.25; interaction P value .032) and detectable BLLs with pre-1950s housing were greater during the COVID-19 period (pre-COVID-19: aOR 1.73, 95% CI 1.35-2.20; COVID-19: aOR 2.56, 95% CI 1.95-3.34; interaction P value .034). CONCLUSIONS: The COVID-19 pandemic led to a significant reduction in lead surveillance and magnified the effect of known risk factors for lead exposure. Concerted clinical, public health, and community advocacy are needed to address care gaps and excess cases of lead poisoning.

ABSTRACT

This study examined caregiver impressions of an electronic consultation and referral (ECR) system. Participants included 56 caregivers of primary care patients referred through the ECR system. Semistructured interviews and surveys were conducted between August 2018 and April 2019. Transcripts were coded and themes developed using thematic content analysis. A total of 51% of caregivers stated that they would prefer to see their child's primary care provider (PCP) for a specialty issue if they could receive the same quality of care. All caregivers who received an electronic consult (n = 28) said that they would utilize that process again. Three themes emerged: (1) caregivers expect immediate action prior to or instead of a specialty referral; (2) caregiver preferences for PCP versus specialist are mediated by both child and provider characteristics; (3) caregiver attitudes toward the ECR system are influenced by external considerations and experiences with the system. Results suggest caregivers value enhanced communication and immediate access to specialty input facilitated by the ECR system.

ABSTRACT

OBJECTIVES: To assess pediatrician adherence to the 2017 American Academy of Pediatrics' clinical practice guideline for high blood pressure (BP). STUDY DESIGN: Pediatric primary care practices (n = 59) participating in a quality improvement collaborative submitted data for patients with high BP measured between November 2018 and January 2019. Baseline data included patient demographics, BP, body mass index (BMI), and actions taken. Logistic regression was used to test associations between patient BP level and BMI with provider adherence to guidelines (BP measurement, counseling, follow-up, evaluation). RESULTS: A total of 2677 patient charts were entered for analysis. Only 2% of patients had all BP measurement steps completed correctly, with fewer undergoing 3-limb and ambulatory BP measurement. Overall, 46% of patients received appropriate weight, nutrition, and lifestyle counseling. Follow-up for high BP was recommended or scheduled in 10% of encounters, and scheduled at the appropriate interval in 5%. For patients presenting with their third high BP measurement, 10% had an appropriate diagnosis documented, 2% had appropriate screening laboratory tests conducted, and none had a renal ultrasound performed. BMI was independently associated with increased odds of counseling, but higher BP was associated with lower odds of counseling. Higher BP was independently associated with an increased likelihood of documentation of hypertension. CONCLUSIONS: In this multisite study, adherence to the 2017 American Academy of Pediatrics' guideline for high BP was low. Given the long-term health implications of high BP in childhood, it is important to improve primary care provider recognition and management. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03783650.

ABSTRACT

Medication administration errors that take place in the home are common, especially when liquid preparations are used and complex medication schedules with multiple medications are involved; children with chronic conditions are disproportionately affected. Parents and other caregivers with low health literacy and/or limited English proficiency are at higher risk for making errors in administering medications to children in their care. Recommended strategies to reduce home medication errors relate to provider prescribing practices; health literacy-informed verbal counseling strategies (eg, teachback and showback) and written patient education materials (eg, pictographic information) for patients and/or caregivers across settings (inpatient, outpatient, emergency care, pharmacy); dosing-tool provision for liquid medication measurement; review of medication lists with patients and/or caregivers (medication reconciliation) that includes prescription and over-the-counter medications, as well as vitamins and supplements; leveraging the medical home; engaging adolescents and their adult caregivers; training of providers; safe disposal of medications; regulations related to medication dosing tools, labeling, packaging, and informational materials; use of electronic health records and other technologies; and research to identify novel ways to support safe home medication administration.

ABSTRACT

BACKGROUND/OBJECTIVES: Patient education is important to families' ability to manage and cope with pediatric atopic dermatitis (AD). We evaluated whether an educational handbook could improve AD symptoms, caregiver confidence in AD management skills, and AD-related quality of life. METHODS: Caregivers of children with AD ages 1 month to 16 years were randomly assigned to the intervention arm (handbook in addition to standard AD management) or the control arm (standard management alone). Caregivers completed self-report outcome questionnaires prior to a clinical visit for AD and at 3-month follow-up. RESULTS: 175 caregivers completed questionnaires at baseline and follow-up. AD symptoms measured by the Patient-Oriented Eczema Measure (POEM) improved in both the handbook and control arms. However, the decrease in the mean POEM score in the handbook arm (-4.4, 95% CI [-5.8, -3.0]) did not differ from that in the control arm (-3.4, 95% CI [-4.8, -2.03]; P = .343). Change in quality of life did not differ between study arms. Among caregivers attending a new patient visit for AD, mean confidence scores (measured from 0 to 100) increased more in the handbook arm (67 [95% CI {60, 74}] to 83 [95% CI {77, 88}]) relative to the control arm (74 [95% CI {65, 82}] to 75 [95% CI {67, 83}]; P = .012). The majority of caregivers rated the handbook as helpful in managing the child's AD. CONCLUSIONS: Despite an adequate sample size, the handbook did not improve AD symptoms more than standard management alone. The handbook improved confidence in management skills for families attending new patient visits for AD.

ABSTRACT

OBJECTIVE: Dermatologic complaints are common in outpatient pediatrics. However, pediatric dermatology specialty care can be difficult to access. We aimed to test the feasibility of co-locating dermatology services within primary care and increase the proportion of patients treated for basic skin complaints within the medical home while decreasing wait times. METHODS: The Rapid Assessment of Skin Health (RASH) clinic was created within a hospital-based primary care clinic in 11/2013. The clinic was staffed by 2 pediatricians trained in the dermatology department and supported with specialist advice as needed. Referral volume and wait times to dermatology and RASH clinic were tracked for visits between 11/1/12 and 10/31/18. A chart review was also conducted on a subset of RASH clinic visits. Primary care providers (PCPs) were surveyed about their experiences. RESULTS: Fifty-eight percent of patients referred for a dermatologic complaint were scheduled in RASH clinic. Wait times for new patient appointments in RASH clinic were significantly shorter than for new dermatology appointments in the previous 12 months (mean 36 days vs 65 days, P < .001). The monthly number of referrals to dermatology also decreased significantly after the RASH clinic opened (24/month vs 12/month, P < .001). Ten percent of RASH patients were referred on to dermatology. In a survey of PCPs (N = 67), 76% said the RASH clinic was "extremely/very helpful." CONCLUSIONS: Providing dermatologic care to low or moderate complexity patients within the medical home is feasible and leads to better access to care. This innovative model could be spread to other clinics and subspecialties.

ABSTRACT

Neonatal lupus erythematosus is a rare autoimmune disease caused by passive transplacental acquisition of maternal autoantibodies manifesting in cutaneous, cardiac, haematological and hepatobiliary abnormalities. The hallmark dermatological finding is erythematous annular lesions with a predilection for photo-exposed areas of the skin. We present a case of a female infant born to a mother with Sjogren's syndrome, who initially presented to an ambulatory care setting with non-specific erythematous papules involving the face and scalp. Within 6 days the rash changed in appearance, consisting of widespread erythematous annular and polycyclic lesions with central violaceous clearing and atrophy. Serological tests revealed asymptomatic anemia and leukopenia, elevated liver enzymes, and positive antinuclear antibodies (ANA) and anti-SSb/La antibodies. Further cardiac evaluation was normal. She was managed conservatively in the outpatient setting with topical steroids, avoidance of sunlight and fluorescent light exposure, and primary care, rheumatological and dermatological follow-up.

ABSTRACT

BACKGROUND/OBJECTIVE: Pediatric hematopoietic stem cell transplantation (HSCT) patients are at an increased risk for skin cancers. Sun exposure is a significant modifiable environmental risk factor. While patient education on sun protection and avoidance behaviors with regular dermatology evaluations are crucial for pediatric HSCT patients, the real-life practice of these sun-protection recommendations in this patient population compared to their peers is unknown. METHODS: A survey-based cross-sectional cohort study was performed in pediatric HSCT patients seen at the Dana-Farber Cancer Institute and Boston Children's Hospital over a 1.5-year period compared with age/sex/Fitzpatrick skin phototype-matched healthy controls. Study participants were surveyed using the validated Glanz survey for pediatric sun protection behavioral research. RESULTS: Eighty-five pediatric HSCT patients and 85 controls completed the study. Pediatric HSCT patients more frequently used sunscreen, hats, umbrellas, and sunglasses and obtained full-body skin exams compared to controls. No difference was observed in sun exposure during hours of peak sun intensity, frequency of purposeful tanning, tanning bed use, and the number of painful sunburns received between pediatric HSCT patients and controls. CONCLUSIONS: Although pediatric HSCT patients practice more sun protection behaviors, they experienced harmful sunburns and intentional tanning behaviors at the same rate as their peers. Patient-directed counseling and strategies to improve patient adherence to optimal sun protection behaviors could have a significant impact on the dermatology quality of life in pediatric HSCT patients.

ABSTRACT

BACKGROUND: Iron deficiency anaemia (IDA) in infancy is prevalent and associated with impaired neurodevelopment; however, studies suggest that treatment and follow-up rates are poor. OBJECTIVES: To improve the rate of ferrous sulfate prescription for suspected IDA among infants aged 8-13 months to 75% or greater within 24 months. METHODS: We implemented a multidisciplinary process improvement effort aimed at standardising treatment for suspected IDA at two academic paediatric primary care clinics. We developed a clinical pathway with screening and treatment recommendations, followed by multiple plan-do-study-act cycles including provider education, targeted reminders when ferrous sulfate was not prescribed and development of standardised procedures for responding to abnormal lab values. We tracked prescription and screening rates using statistical process control charts. In post hoc analyses, we examined rates of haemoglobin (Hgb) recheck and normalisation for the preintervention versus postintervention groups. RESULTS: The prescription rate for suspected IDA increased from 41% to 78% following implementation of the intervention. Common reasons for treatment failure included prescription of a multivitamin instead of ferrous sulfate, and Hgb not flagged as low by the electronic medical record. Screening rates remained stable at 89%. Forty-one per cent of patients with anaemia in the preintervention group had their Hgb rechecked within 6 months, compared with 56% in the postintervention group (p<0.001). Furthermore, 30% of patients with anaemia in the postintervention group had normalised their Hgb by 6 months, compared with 20% in the preintervention group (p<0.05). CONCLUSIONS: A multipronged interdisciplinary quality improvement intervention enabled: (1) development of standardised practices for treating suspected IDA among infants aged 8-13 months, (2) improvement of prescription rates and (3) maintenance of high screening rates. Rates of Hgb recheck and normalisation also increased in the intervention period.​.

ABSTRACT

There is growing emphasis on using patient-reported outcome measures to enhance clinical practice. This study was a retrospective review of scores on the Childhood Asthma Control Test (C-ACT) and the Pediatric Symptom Checklist-17 (PSC-17) at a pediatric primary care center in Boston, Massachusetts. A total of 218 patients were selected at random using billing codes for well-child (WC) care and asthma, excluding complex medical conditions. Cutoff scores were used to identify uncontrolled asthma (C-ACT ⩽19) and clinically significant psychosocial symptoms (+PSC-17). Multiple logistic regression was used to measure associations between C-ACT ⩽19 and +PSC-17, adjusting for covariates. In multivariable analysis, C-ACT ⩽19 at WC visits was associated with +PSC-17 at WC visits (adjusted odds ratio = 3.2 [95% confidence interval = 1.3-8.6]). C-ACT ⩽19 at non-WC visits was also associated with +PSC-17 at WC visits (adjusted odds ratio = 3.1 [95% confidence interval = 1.2-8.9]). Patient-reported outcome measures of asthma control and psychosocial symptoms were positively correlated in this sample.

ABSTRACT

Systemic hypertension is a major cause of morbidity and mortality in adulthood. High blood pressure (HBP) and repeated measures of HBP, hypertension (HTN), begin in youth. Knowledge of how best to diagnose, manage, and treat systemic HTN in children and adolescents is important for primary and subspecialty care providers. OBJECTIVES: To provide a technical summary of the methodology used to generate the 2017 "Clinical Practice Guideline for Screening and Management of High Blood Pressure in Children and Adolescents," an update to the 2004 "Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents." DATA SOURCES: Medline, Cochrane Central Register of Controlled Trials, and Excerpta Medica Database references published between January 2003 and July 2015 followed by an additional search between August 2015 and July 2016. STUDY SELECTION: English-language observational studies and randomized trials. METHODS: Key action statements (KASs) and additional recommendations regarding the diagnosis, management, and treatment of HBP in youth were the product of a detailed systematic review of the literature. A content outline establishing the breadth and depth was followed by the generation of 4 patient, intervention, comparison, outcome, time questions. Key questions addressed: (1) diagnosis of systemic HTN, (2) recommended work-up of systemic HTN, (3) optimal blood pressure (BP) goals, and (4) impact of high BP on indirect markers of cardiovascular disease in youth. Once selected, references were subjected to a 2-person review of the abstract and title followed by a separate 2-person full-text review. Full citation information, population data, findings, benefits and harms of the findings, as well as other key reference information were archived. Selected primary references were then used for KAS generation. Level of evidence (LOE) scoring was assigned for each reference and then in aggregate. Appropriate language was used to generate each KAS based on the LOE and the balance of benefit versus harm of the findings. Topics that could not be researched via the stated approach were (1) definition of HTN in youth, and (2) definition of left ventricular hypertrophy. KASs related to these stated topics were generated via expert opinion. RESULTS: Nearly 15 000 references were identified during an initial literature search. After a deduplication process, 14 382 references were available for title and abstract review, and 1379 underwent full text review. One hundred twenty-four experimental and observational studies published between 2003 and 2016 were selected as primary references for KAS generation, followed by an additional 269 primary references selected between August 2015 and July 2016. The LOE for the majority of references was C. In total, 30 KASs and 27 additional recommendations were generated; 12 were related to the diagnosis of HTN, 13 were related to management and additional diagnostic testing, 3 to treatment goals, and 2 to treatment options. Finally, special additions to the clinical practice guideline included creation of new BP tables based on BP values obtained solely from children with normal weight, creation of a simplified table to enhance screening and recognition of abnormal BP, and a revision of the criteria for diagnosing left ventricular hypertrophy. CONCLUSIONS: An extensive and detailed systematic approach was used to generate evidence-based guidelines for the diagnosis, management, and treatment of youth with systemic HTN.

ABSTRACT

We investigated factors associated with quality of life (QOL) in children with eczema. We conducted a cross-sectional analysis of survey data from 224 parents of children with eczema attending a large, hospital-based pediatric clinic. Parents completed a validated eczema severity scale (Patient-Oriented Eczema Measure), a QOL scale (Infants' Dermatitis QOL Index or Children's Dermatology Life Quality Index), and a knowledge and understanding questionnaire. In adjusted multivariate analyses, worse eczema severity was associated with worse overall QOL (ß = 0.5; 95% confidence interval [CI] = [0.5, 0.6]), while a higher knowledge score was associated with better QOL (ß = -3.4; 95% CI = [-6.6, -0.2]). Similarly, even after adjustment for eczema severity, greater understanding of a child's individual treatment plan was associated with better QOL (ß = -0.7; 95% CI = [-1.4, -0.08]), while increased frequency of worrying about a child's eczema was associated with worse QOL (ß = 0.7; 95% CI = [0.03, 1.1]). These results suggest primary care providers may be able to influence QOL through optimal eczema management and family education.

ABSTRACT

BACKGROUND AND OBJECTIVES: Timely provision of developmental services can improve outcomes for children 0 to 3 years old with developmental delays. Early Intervention (EI) provides free developmental services to children under age 3 years; however, data suggests that many children referred to EI never connect to the program. We sought to ensure that 70% of patients referred to EI from an academic primary care clinic serving a low-income population were evaluated within 120 days of referral. METHODS: Recognizing that our baseline system of EI referrals had multiple routes to referral without an ability to track referral outcome, we implemented a multifaceted referral process with (1) a centralized electronic referral system used by providers, (2) patient navigators responsible for processing all EI referrals submitted by providers, and (3) a tracking system postreferral to facilitate identification of patients failing to connect with EI. RESULTS: The percentage of patients evaluated by EI within 120 days increased from a baseline median of 50% to a median of 72% after implementation of the systems (N = 309). After implementation, the centralized referral system was used a median of 90% of the time. Tracking of referral outcomes revealed decreases in families refusing evaluations and improvements in exchange of information with EI. CONCLUSIONS: Rates of connection to EI improved substantially when referrals were centralized in the clinic and patient navigators were responsible for tracking referral outcomes. Knowledge of EI intake processes and relationships between the practice and the EI site are essential to ensure successful connections.
