Annual Prevalence of Opioid Receipt by South Carolina Medicaid-Enrolled Children and Adolescents: 2000-2020.

Understanding patterns of opioid receipt by children and adolescents over time and understanding differences between age groups can help identify opportunities for future opioid stewardship. We conducted a retrospective cohort study, using South Carolina Medicaid data for children and adolescents 0-18 years old between 2000-2020, calculating the annual prevalence of opioid receipt for medical diagnoses in ambulatory settings. We examined differences in prevalence by calendar year, race/ethnicity, and by age group. The annual prevalence of opioid receipt for medical diagnoses changed significantly over the years studied, from 187.5 per 1000 in 2000 to 41.9 per 1000 in 2020 (Cochran-Armitage test for trend, p < 0.0001). In all calendar years, older ages were associated with greater prevalence of opioid receipt. Adjusted analyses (logistic regression) assessed calendar year differences in opioid receipt, controlling for age group, sex, and race/ethnicity. In the adjusted analyses, calendar year was inversely associated with opioid receipt (aOR 0.927, 95% CI 0.926-0.927). Males and older ages were more likely to receive opioids, while persons of Black race and Hispanic ethnicity had lower odds of receiving opioids. While opioid receipt declined among all age groups during 2000-2020, adolescents 12-18 had persistently higher annual prevalence of opioid receipt when compared to younger age groups.

Deimplementation of Polycythemia Screening in Asymptomatic Infants in a Level 1 Nursery.

Polycythemia (venous hematocrit >65%) is rare in healthy newborns (incidence: 0.4%-5%), with serious outcomes (stroke, bowel ischemia) of unknown incidence in asymptomatic infants. No national guidelines address screening or management of asymptomatic infants with polycythemia. Our nursery screened "high risk" (HR) newborns (small for gestational age, large for gestational age, twin, infant of diabetic mother) with poor adherence and low yield. We aimed to decrease polycythemia screening of asymptomatic HR infants by 80% within 6 months. Methods: We conducted an improvement project at a tertiary children's hospital using the Model for Improvement. Eligible infants had an HR ICD-10 code on their problem list, were asymptomatic, over 35 weeks gestational age, and remained in the nursery for >6 hrs. Interventions included discontinuation of prior protocol, education for staff, bimonthly feedback on project performance, and visual reminders. Our primary outcome measure was the proportion of asymptomatic infants who received a hematocrit screen. Secondary measures were screening costs. Balancing measures were the length of stay, detected/symptomatic polycythemia, transfers to ICU/wards, and readmissions within 1 week of discharge. Results: The Nursery unit screened 80% of HR infants at baseline. This decreased to 7.3% after PDSA1, 0% after PDSA2, and 1% after PDSA3. There was no symptomatic polycythemia or statistically significant increase in readmissions/transfers. One month of monitoring revealed persistent changes. Conclusion: Simple quality improvement interventions such as education, reminders, and feedback can facilitate the deimplementation of low-value practices.

Pediatric surgical site infection (SSI) following ambulatory surgery: Incidence, risk factors and patient outcomes.

BACKGROUND: Inpatient surgical site infections (SSIs) cause morbidity in children. The SSI rate among pediatric ambulatory surgery patients is less clear. To fill this gap, we conducted a multiple-institution, retrospective epidemiologic study to identify incidence, risk factors, and outcomes. METHODS: We identified patients aged <22 years with ambulatory visits between October 2010 and September 2015 via electronic queries at 3 medical centers. We performed sample chart reviews to confirm ambulatory surgery and adjudicate SSIs. Weighted Poisson incidence rates were calculated. Separately, we used case-control methodology using multivariate backward logistical regression to assess risk-factor association with SSI. RESULTS: In total, 65,056 patients were identified by queries, and we performed complete chart reviews for 13,795 patients; we identified 45 SSIs following ambulatory surgery. The weighted SSI incidence following pediatric ambulatory surgery was 2.00 SSI per 1,000 ambulatory surgeries (95% confidence interval [CI], 1.37-3.00). Integumentary surgeries had the highest weighted SSI incidence, 3.24 per 1,000 ambulatory surgeries (95% CI, 0.32-12). The following variables carried significantly increased odds of infection: clean contaminated or contaminated wound class compared to clean (odds ratio [OR], 9.8; 95% CI, 2.0-48), other insurance type compared to private (OR, 4.0; 95% CI, 1.6-9.8), and surgery on weekend day compared to weekday (OR, 30; 95% CI, 2.9-315). Of the 45 instances of SSI following pediatric ambulatory surgery, 40% of patients were admitted to the hospital and 36% required a new operative procedure or bedside incision and drainage. CONCLUSIONS: Our findings suggest that morbidity is associated with SSI following ambulatory surgery in children, and we also identified possible targets for intervention.

Pediatrician Adherence to Guidelines for Diagnosis and Management of High Blood Pressure.

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.

Central Venous Catheter Salvage in Ambulatory Central Line-Associated Bloodstream Infections.

BACKGROUND: Guidelines for treatment of central line-associated bloodstream infection (CLABSI) recommend removing central venous catheters (CVCs) in many cases. Clinicians must balance these recommendations with the difficulty of obtaining alternate access and subjecting patients to additional procedures. In this study, we evaluated CVC salvage in pediatric patients with ambulatory CLABSI and associated risk factors for treatment failure. METHODS: This study was a secondary analysis of 466 ambulatory CLABSIs in patients <22 years old who presented to 5 pediatric medical centers from 2010 to 2015. We defined attempted CVC salvage as a CVC left in place ≥3 days after a positive blood culture result. Salvage failure was removal of the CVC ≥3 days after CLABSI. Successful salvage was treatment of CLABSI without removal of the CVC. Bivariate and multivariable logistic regression analyses were used to test associations between risk factors and attempted and successful salvage. RESULTS: A total of 460 ambulatory CLABSIs were included in our analysis. CVC salvage was attempted in 379 (82.3%) cases. Underlying diagnosis, CVC type, number of lumens, and absence of candidemia were associated with attempted salvage. Salvage was successful in 287 (75.7%) attempted cases. Underlying diagnosis, CVC type, number of lumens, and absence of candidemia were associated with successful salvage. In patients with malignancy, neutropenia within 30 days before CLABSI was significantly associated with both attempted salvage and successful salvage. CONCLUSIONS: CVC salvage was often attempted and was frequently successful in ambulatory pediatric patients presenting with CLABSI.

Pediatric Ambulatory Central Line-Associated Bloodstream Infections.

BACKGROUND: Inpatient pediatric central line-associated bloodstream infections (CLABSIs) cause morbidity and increased health care use. Minimal information exists for ambulatory CLABSIs despite ambulatory central line (CL) use in children. In this study, we identified ambulatory pediatric CLABSI incidence density, risk factors, and outcomes. METHODS: Retrospective cohort with nested case-control study at 5 sites from 2010 through 2015. Electronic queries were used to identify potential cases on the basis of administrative and laboratory data. Chart review was used to confirm ambulatory CL use and adjudicated CLABSIs. Bivariate followed by multivariable backward logistic regression was used to identify ambulatory CLABSI risk factors. RESULTS: Queries identified 4600 potentially at-risk children; 1658 (36%) had ambulatory CLs. In total, 247 (15%) patients experienced 466 ambulatory CLABSIs with an incidence density of 0.97 CLABSIs per 1000 CL days. Incidence density was highest among patients with tunneled externalized catheters versus peripherally inserted central catheters and totally implanted devices: 2.58 CLABSIs per 1000 CL days versus 1.46 vs 0.23, respectively (P < .001). In a multivariable model, clinic visit (odds ratio [OR] 2.8; 95% confidence interval [CI]: 1.4-5.5) and low albumin (OR 2.3; 95% CI: 1.2-4.3) were positively associated with CLABSI, and prophylactic antimicrobial agents for underlying conditions within the preceding 30 days (OR 0.22; 95% CI: 0.12-0.40) and operating room CL placement (OR 0.36; 95% CI: 0.16-0.79) were inversely associated with CLABSI. A total of 396 patients (85%) were hospitalized because of ambulatory CLABSI with an 8-day median length of stay (interquartile range 5-13). CONCLUSIONS: Ambulatory pediatric CLABSI incidence density is appreciable and associated with health care use. CL type, patients with low albumin, prophylactic antimicrobial agents, and placement setting may be targets for reduction efforts.

Costs of ambulatory pediatric healthcare-associated infections: Central-line-associated bloodstream infection (CLABSIs), catheter-associated urinary tract infection (CAUTIs), and surgical site infections (SSIs).

OBJECTIVE: Ambulatory healthcare-associated infections (HAIs) occur frequently in children and are associated with morbidity. Less is known about ambulatory HAI costs. This study estimated additional costs associated with pediatric ambulatory central-line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTI), and surgical site infections (SSIs) following ambulatory surgery. DESIGN: Retrospective case-control study. SETTING: Four academic medical centers. PATIENTS: Children aged 0-22 years seen between 2010 and 2015 and at risk for HAI as identified by electronic queries. METHODS: Chart review adjudicated HAIs. Charges were obtained for patients with HAIs and matched controls 30 days before HAI, on the day of, and 30 days after HAI. Charges were converted to costs and 2015 USD. Mixed-effects linear regression was used to estimate the difference-in-differences of HAI case versus control costs in 2 models: unrecorded charge values considered missing and a sensitivity analysis with unrecorded charge considered $0. RESULTS: Our search identified 177 patients with ambulatory CLABSIs, 53 with ambulatory CAUTIs, and 26 with SSIs following ambulatory surgery who were matched with 382, 110, and 75 controls, respectively. Additional cost associated with an ambulatory CLABSI was $5,684 (95% confidence interval [CI], $1,005-$10,362) and $6,502 (95% CI, $2,261-$10,744) in the 2 models; cost associated with a CAUTI was $6,660 (95% CI, $1,055, $12,145) and $2,661 (95% CI, -$431 to $5,753); cost associated with an SSI following ambulatory surgery at 1 institution only was $6,370 (95% CI, $4,022-$8,719). CONCLUSIONS: Ambulatory HAI in pediatric patients are associated with significant additional costs. Further work is needed to reduce ambulatory HAIs.

Contributing Factors for Pediatric Ambulatory Diagnostic Process Errors: Project RedDE.

BACKGROUND: Pediatric ambulatory diagnostic errors (DEs) occur frequently. We used root cause analyses (RCAs) to identify their failure points and contributing factors. METHODS: Thirty-one practices were enrolled in a national QI collaborative to reduce 3 DEs occurring at different stages of the diagnostic process: missed adolescent depression, missed elevated blood pressure (BP), and missed actionable laboratory values. Practices were encouraged to perform monthly "mini-RCAs" to identify failure points and prioritize interventions. Information related to process steps involved, specific contributing factors, and recommended interventions were reported monthly. Data were analyzed using descriptive statistics and Pareto charts. RESULTS: Twenty-eight (90%) practices submitted 184 mini-RCAs. The median number of mini-RCAs submitted was 6 (interquartile range, 2-9). For missed adolescent depression, the process step most commonly identified was the failure to screen (68%). For missed elevated BP, it was the failure to recognize (36%) and act on (28%) abnormal BP. For missed actionable laboratories, failure to notify families (23%) and document actions on (19%) abnormal results were the process steps most commonly identified. Top contributing factors to missed adolescent depression included patient volume (16%) and inadequate staffing (13%). Top contributing factors to missed elevated BP included patient volume (12%), clinic milieu (9%), and electronic health records (EHRs) (8%). Top contributing factors to missed actionable laboratories included written communication (13%), EHR (9%), and provider knowledge (8%). Recommended interventions were similar across errors. CONCLUSIONS: EHR-based interventions, standardization of processes, and cross-training may help decrease DEs in the pediatric ambulatory setting. Mini-RCAs are useful tools to identify their contributing factors and interventions.

Pediatric ambulatory catheter-associated urinary tract infections (CAUTIs): Incidence, risk factors, and patient outcomes.

OBJECTIVE: Catheter-associated urinary tract infections (CAUTIs) occur frequently in pediatric inpatients, and they are associated with increased morbidity and cost. Few studies have investigated ambulatory CAUTIs, despite at-risk children utilizing home urinary catheterization. This retrospective cohort and case-control study determined incidence, risk factors, and outcomes of pediatric patients with ambulatory CAUTI. DESIGN: Broad electronic queries identified potential patients with ambulatory urinary catheters, and direct chart review confirmed catheters and adjudicated whether ambulatory CAUTI occurred. CAUTI definitions included clean intermittent catheterization (CIC). Our matched case-control analysis assessed risk factors. SETTING: Five urban, academic medical centers, part of the New York City Clinical Data Research Network. PATIENTS: Potential patients were age <22 years who were seen between October 2010 and September 2015. RESULTS: In total, 3,598 eligible patients were identified; 359 of these used ambulatory catheterization (representing186,616 ambulatory catheter days). Of these, 63 patients (18%) experienced 95 ambulatory CAUTIs. The overall ambulatory CAUTI incidence was 0.51 infections per 1,000 catheter days (1.35 for indwelling catheters and 0.47 for CIC; incidence rate ratio, 2.88). Patients with nonprivate medical insurance (odds ratio, 2.5; 95% confidence interval, 1.1-6.3) were significantly more likely to have ambulatory CAUTIs in bivariate models but not multivariable models. Also, 45% of ambulatory CAUTI resulted in hospitalization (median duration, 3 days); 5% resulted in intensive care admission; 47% underwent imaging; and 88% were treated with antibiotics. CONCLUSIONS: Pediatric ambulatory CAUTIs occur in 18% of patients with catheters; they are associated with morbidity and healthcare utilization. Ambulatory indwelling catheter CAUTI incidence exceeded national inpatient incidence. Future quality improvement research to reduce these harmful infections is warranted.

Mucosal barrier injury-associated bloodstream infections in pediatric oncology patients.

BACKGROUND: Single-center reports of central line-associated bloodstream infection (CLABSI) and the subcategory of mucosal barrier injury laboratory-confirmed bloodstream infection (MBI-LCBI) in pediatric hematology oncology transplant (PHO) patients have focused on the inpatient setting. Characterization of MBI-LCBI across PHO centers and management settings (inpatient and ambulatory) is urgently needed to inform surveillance and prevention strategies. METHODS: Prospectively collected data from August 1, 2013, to December 31, 2015, on CLABSI (including MBI-LCBI) from a US PHO multicenter quality improvement network database was analyzed. CDC National Healthcare Safety Network definitions were applied for inpatient events and adapted for ambulatory events. RESULTS: Thirty-five PHO centers reported 401 ambulatory and 416 inpatient MBI-LCBI events. Ambulatory and inpatient MBI-LCBI rates were 0.085 and 1.01 per 1000 line days, respectively. Fifty-three percent of inpatient CLABSIs were MBI-LCBIs versus 32% in the ambulatory setting (P  <  0.01). Neutropenia was the most common criterion defining MBI-LCBI in both settings, being present in ≥90% of events. The most common organisms isolated in MBI-LCBI events were Escherichia coli (in 28% of events), Klebsiella spp. (23%), and viridans streptococci (12%) in the ambulatory setting and viridans streptococci (in 29% of events), E. coli (14%), and Klebsiella spp. (14%) in the inpatient setting. CONCLUSION: In this largest study of PHO MBI-LCBI inpatient events and the first such study in the ambulatory setting, the burden of MBI-LCBI across the continuum of care of PHO patients was substantial. These data should raise awareness of MBI-LCBI among healthcare providers for PHO patients, help benchmarking across centers, and help inform prevention and treatment strategies.

Cluster Randomized Trial Reducing Missed Elevated Blood Pressure in Pediatric Primary Care: Project RedDE.

Recognition of childhood hypertension is essential, but pediatricians routinely fail to identify elevated blood pressure (BP). This study investigated if a quality improvement collaborative (QIC) reduces missed elevated BP in primary care. METHODS: During a cluster-randomized clinical trial, a national cohort worked sequentially to reduce each of three different errors, including missed elevated BP. While working on their first error during an 8-month action period, practices collected control data for a different error. Practices worked to reduce two additional errors in subsequent action periods but continued to provide sustain and maintainenance data on BP. QIC intervention included video learning sessions, transparent data, failures analysis, coaching, and tools to reduce errors. Mixed-effects logistic regression models compared the mean percentage of patients with an elevated BP with appropriate actions taken and documented. RESULTS: We randomized 43 practices and included 30 in the final analysis. Control and intervention phases included 1,728 and 1,834 patients with an elevated BP, respectively. Comparing control versus intervention phases, the mean percentage of patients who received appropriate actions increased from 58% to 74% [risk difference (RD) 16%; 95% CI;12%, 20%]. Practices continued to improve during the sustain phase as compared to the intervention phase (RD 5%; 95% CI; 2%, 9%) and did not worsen during the maintenance phase (RD 0.9%; 95% CI -5%, 7%). CONCLUSIONS: Missed pediatric elevated BP can be sustainably reduced via a QIC intervention, demonstrating a possible model for other error reduction efforts.

Increasing Recognition and Diagnosis of Adolescent Depression: Project RedDE: A Cluster Randomized Trial.

Adolescent depression causes appreciable morbidity and is underdiagnosed in primary care. This study investigated whether a quality improvement collaborative (QIC) increases the frequency of adolescent depression diagnoses, thus reducing missed diagnoses. METHODS: During a cluster-randomized clinical trial, a national cohort of primary care pediatric practices worked in different orders based on randomization to improve performance on each of three different diagnoses; one was increasing adolescent depression diagnoses. While improving their first diagnosis during an 8-month action period, practices collected control data for a different diagnosis. In two subsequent 8-month periods, practices worked to improve two additional diagnoses and continued to provide data on the ability to sustain and maintain improvements. The QIC intervention included day-long video conferences, transparent data sharing, analysis of failures, QI coaching, and tools to help improve diagnostic performance, including the Patient Health Questionnaire-9 Modified. The primary outcome was the measured frequency of depression diagnoses in adolescent health supervision visits compared via generalized mixed-effects regression models. RESULTS: Forty-three practices were randomized with 31 in the final analysis. We included 3,394 patient visits in the control and 4,114 in the intervention phases. The adjusted percentage of patients with depression diagnoses increased from 6.6% in the control to 10.5% in intervention phase (Risk Difference (RD) 3.9%; 95% CI 2.4%, 5.3%). Practices sustained these increases while working on different diagnoses during the second (RD -0.4%; 95% CI -2.3, 1.4%), and third action periods (RD -0.1%; 95% CI -2.7%, 2.4%). CONCLUSIONS: A QIC intervention can sustainably increase adolescent depression diagnoses.

Project RedDE: Cluster Randomized Trial to Reduce Missed or Delayed Abnormal Laboratory Value Actions.

Failure of timely abnormal laboratory result follow-up is relatively common and may lead to harm. This study hypothesized that a quality improvement collaborative (QIC) could reduce the frequency of missed or delayed action on abnormal laboratory values. METHODS: A national cohort of pediatric practices was cluster-randomized to sequentially receive a QIC intervention: video conferences, transparent data sharing, a "focus on failures," QI coaching, and tools to help reduce missed or delayed action on abnormal laboratory values. Practices recorded the percentage of patients with 5 specific abnormal laboratory values who received an appropriate provider action (control), and then, during an 8-month intervention phase, implemented QI strategies to reduce errors (intervention). Subsequently, practices collected data on laboratory errors while working to reduce unrelated second (sustain phase), and third (maintenance phase) errors. Generalized mixed-effects regression models compared the mean percentage of patients with appropriate actions. RESULTS: We randomized 43 practices, of which 31 were included in analyses. Control and intervention phases included 1,357 and 1,426 patients with abnormal laboratory values, respectively. The mean percentage of patients who received appropriate actions did not change comparing control and intervention phases [risk difference (RD) 1%; 95% CI -1%, 3%]. In post-hoc analyses, practices significantly improved comparing control to sustain (RD 3%; 95% CI 0.3%, 6%) and maintenance phases (RD 6%; 95% CI 3%, 9%). CONCLUSION: Implementation of a QIC did not reduce the frequency of abnormal laboratory errors in the initial 8-month intervention phase. A significant reduction was appreciated comparing sustain and maintenance phases (months 9-24) to the control phase.

Comparison of Attention-Deficit/Hyperactivity Disorder Care Between School-Based Health Centers and a Continuity Clinic.

BACKGROUND: School-based health centers (SBHC) are in a unique position to provide guideline-driven attention-deficit/hyperactivity disorder (ADHD) care. In this study, we compared adherence to 2 components of ADHD guidelines in SBHC versus a continuity clinic. METHODS: We compared proportions of ADHD visits that had a structured symptom report available and timely follow-up in SBHC to a continuity clinic using chart review. We used multiple logistic regression to estimate the association between guideline adherence and clinic type. RESULTS: Participants who had a medication dose change were 3.9 times more likely (relative risk [RR] = 3.9, 95% confidence interval [CI] 3.0-5.1) to have a structured report present and 1.7 times more likely (RR = 1.7, 95% CI 1.2-2.2) to have follow-up within 30 days if they were seen in SBHC versus continuity clinic. Participants who were stable on their medication dose were 18 times more likely (RR = 18.0, 95% CI 11.3-29.0) to have a structured report present and 1.4 times more likely (RR = 1.4, 95% CI 1.3-1.6) to have follow-up within 100 days if they were seen in SBHC versus continuity clinic. CONCLUSIONS: Care provided in SBHC was associated with improved adherence to guidelines and has the potential to the improve pediatric ADHD outcomes.

Pediatric Hospitalizations: Are We Missing an Opportunity to Immunize?

OBJECTIVES: Fewer than half of children receive all recommended immunizations on time. Hospitalizations may be opportunities to address delayed immunizations. Our objectives were to assess (1) prevalence of delayed immunizations among hospitalized patients, (2) missed opportunities to administer delayed immunizations, and (3) time to catch up after discharge. METHODS: We conducted a retrospective cohort study investigating immunization status of patients 0 to 21 years of age admitted to an academic children's center from 2012 to 2013 at the time of admission, at discharge, and 18 months postdischarge. Immunization catch-up at 18 months postdischarge was defined as having received immunizations due on discharge per Centers for Disease Control and Prevention recommendations. χ2 and t test analyses compared characteristics among patients caught up and not caught up at 18 months postdischarge. Analysis of variance and logistic regression analyses compared mean number of immunizations needed and odds of immunization catch-up among age groups. Kaplan-Meier and Cox proportional hazards analyses compared catch-up time by age, race, sex, and insurance. RESULTS: Among 166 hospitalized patients, 80 were not up to date on immunizations at admission, and only 1 received catch-up immunizations before discharge. Ninety-nine percent (79 of 80) were not up to date on discharge per Centers for Disease Control and Prevention recommendations. Thirty percent (24 of 79), mostly adolescents, were not caught up at 18 months postdischarge. Median postdischarge catch-up time was 3.5 months (range: 0.03-18.0 months). Patients 0 to 35 months of age were more likely to catch up compared with those of other ages (hazard ratio = 2.73; P = .001), with no differences seen when comparing race, sex, or insurance. CONCLUSIONS: Pediatric hospitalizations provide important opportunities to screen and immunize children.

Hydroxyurea Use for Sickle Cell Disease Among Medicaid-Enrolled Children.

BACKGROUND: Recent publications should have resulted in increased hydroxyurea usage in children with sickle cell disease (SCD). We hypothesized that hydroxyurea use in children with SCD increased over time and was associated with decreased acute care visits. METHODS: This was a secondary analysis of the Truven Health Analytics-IBM Watson Health MarketScan Medicaid database from 2009 to 2015. The multistate, population-based cohort included children 1 to 19 years old with an International Classification of Diseases, Ninth or 10th Revision diagnosis of SCD between 2009 and 2015. Changes in hydroxyurea were measured across study years. The primary outcome was the receipt of hydroxyurea, identified through filled prescription claims. Acute care visits (emergency department visits and hospitalizations) were extracted from billing data. RESULTS: A mean of 5138 children each year were included. Hydroxyurea use increased from 14.3% in 2009 to 28.2% in 2015 (P < .001). During the study period, the acute-care-visit rate decreased from 1.20 acute care visits per person-year in 2009 to 1.04 acute care visits per person-year in 2015 (P < .001); however, the drop in acute care visits was exclusively in the youngest and oldest age groups and was not seen when only children enrolled continuously from 2009 to 2015 were analyzed. CONCLUSIONS: There was a significant increase in hydroxyurea use in children with SCD between 2009 and 2015. However, in 2015, only ∼1 in 4 children with SCD received hydroxyurea at least once. Increases in hydroxyurea were not associated with consistently decreased acute care visits in this population-based study of children insured by Medicaid.

The design and conduct of Project RedDE: A cluster-randomized trial to reduce diagnostic errors in pediatric primary care.

BACKGROUND: Diagnostic errors contribute to the large burden of healthcare-associated harm experienced by children. Primary care settings involve high diagnostic uncertainty and limited time and information, creating ideal conditions for diagnostic errors. We report on the design and conduct of Project RedDE, a stepped-wedge, cluster-randomized controlled trial of a virtual quality improvement collaborative aimed at reducing diagnostic errors in pediatric primary care. METHODS: Project RedDE cluster-randomized pediatric primary care practices into one of three groups. Each group participated in a quality improvement collaborative targeting the same three diagnostic errors (missed diagnoses of elevated blood pressure and adolescent depression and delayed diagnoses of abnormal laboratory studies), but in a different sequence. During the quality improvement collaborative, practices worked both independently and collaboratively, leveraging general quality improvement strategies (e.g. process mapping) in addition to error-specific content (e.g. pocket guides for blood pressure norms) delivered during the intervention phase for each error. The quality improvement collaborative intervention included interactive learning sessions and webinars, quality improvement coaching at the team level, and repeated evaluation of failures via root cause analyses. Pragmatic data were collected monthly, submitted to a centralized data aggregator, and returned to the practices in the form of run charts comparing each practice's progress over time to that of the group. The primary analysis used patients as the unit of analysis and compared diagnostic error proportions between the intervention and baseline periods, while secondary analyses evaluated the sustainability of observed reductions in diagnostic errors after the intervention period ended. RESULTS: A total of 43 practices were recruited and randomized into Project RedDE. Eleven practices withdrew before submitting any data, and one practice merged with another participating practice, leaving 31 practices that began work on Project RedDE. All but one of the diverse, national pediatric primary care practices that participated ultimately submitted complete data. Quality improvement collaborative participation was robust, with an average of 63% of practices present on quality improvement collaborative webinars and 85% of practices present for quality improvement collaborative learning sessions. Complete data included 30 months of outcome data for the first diagnostic error worked on, 24 months of outcome data for the second, and 16 months of data for the third. LESSONS LEARNED AND LIMITATIONS: Contamination across study groups was a recurring concern; concerted efforts were made to mitigate this risk. Electronic health records played a large role in teams' success. CONCLUSION: Project RedDE, a virtual quality improvement collaborative aimed at reducing diagnostic errors in pediatric primary care, successfully recruited and retained a diverse, national group of pediatric primary care practices. The stepped-wedge, cluster-randomized controlled trial design allowed for enhanced scientific efficiency.

Effect of Mental Health Screening and Integrated Mental Health on Adolescent Depression-Coded Visits.

Adolescent depression causes morbidity and is underdiagnosed. It is unclear how mental health screening and integrated mental health practitioners change adolescent depression identification. We conducted a retrospective primary care network natural cohort study where 10 out of 19 practices implemented mental health screening, followed by the remaining 9 practices implementing mental health screening with less coaching and support. Afterward, a different subset of 8 practices implemented integrated mental health practitioners. Percentages of depression-coded adolescent visits were compared between practices (1) with and without mental health screening and (2) with and without integrated mental health practitioners, using difference-in-differences analyses. The incidence of depression-coded visits increased more in practices that performed mental health screening (ratio of odds ratios = 1.22; 95% confidence interval =1.00-1.49) and more in practices with integrated mental health practitioners (ratio of odds ratios = 1.58; 95% confidence interval = 1.30-1.93). Adolescent mental health screening and integrated mental health practitioners increase depression-coded visits in primary care.
