Parent-Reported Symptoms and Medications Used Among Children With Severe Neurological Impairment.

Importance: Children with severe neurological impairment (SNI) often take multiple medications to treat problematic symptoms. However, for children who cannot self-report symptoms, no system exists to assess multiple symptoms and their association with medication use. Objectives: To assess the prevalence of 28 distinct symptoms, test whether higher global symptom scores (GSS) were associated with use of more medications, and assess the associations between specific symptoms and medications. Design, Setting, and Participants: This cross-sectional study was conducted between April 1, 2019, and December 31, 2019, using structured parent-reported symptom data paired with clinical and pharmacy data, at a single-center, large, hospital-based special health care needs clinic. Participants included children aged 1 to 18 years with SNI and 5 or more prescribed medications. Data analysis was performed from April to June 2020. Exposure: During routine clinical visits, parent-reported symptoms were collected using the validated 28-symptom Memorial Symptom Assessment Scale (MSAS) and merged with clinical and pharmacy data. Main Outcomes and Measures: Symptom prevalence, counts, and GSS (scored 0-100, with 100 being the worst) were calculated, and the association of GSS with medications was examined. To evaluate associations between symptom-medication pairs, the proportion of patients with a symptom who used a medication class or specific medication was calculated. Results: Of 100 patients, 55.0% were boys, the median (interquartile range [IQR]) age was 9 (5-12) years, 62.0% had 3 or more complex chronic conditions, 76.0% took 10 or more medications, and none were able to complete the MSAS themselves. Parents reported a median (IQR) of 7 (4-10) concurrent active symptoms. The median (IQR) GSS was 12.1 (5.4-20.8) (range, 0.0-41.2) and the GSS was 9.8 points (95% CI, 5.5-14.1 points) higher for those with worse recent health than usual. Irritability (65.0%), insomnia (55.0%), and pain (54.0%) were the most prevalent symptoms. Each 10-point GSS increase was associated with 12% (95% CI, 4%-19%) higher medication counts, adjusted for age and complex chronic condition count. Among the 54.0% of children with reported pain, 61.0% were prescribed an analgesic. Conclusions and Relevance: These findings suggest that children with SNI reportedly experience substantial symptom burdens and that higher symptom scores are associated with increased medication use. Paired symptom-medication data may help clinicians identify targets for personalized symptom management, including underrecognized or undertreated symptoms.

Increased Odds of Ventricular Arrhythmias Associated with Selective Serotonin Reuptake Inhibitor Use among the Pediatric and Young Adult Population: A Case-Control Study.

OBJECTIVE: To measure the association between selective serotonin reuptake inhibitor (SSRI) use and out-of-hospital ventricular arrhythmia among the pediatric and young adult population. STUDY DESIGN: Case-control study using US claims data from 2007 to 2018. Cases were subjects with at least 1 event between ages 2 and 24 years. Controls (matched 10:1 on index date, age, sex, and continuous enrollment) had no events during study period. Independent association between current SSRI use (prescription fill with continuous exposure ending on, or after, the index date) and incident out-of-hospital ventricular arrhythmia (hospitalization or emergency room encounter with primary diagnostic code for ventricular arrhythmia) was estimated using multivariable conditional logistic regression. Separate analyses were performed for pediatric (2-17 years of age) vs young adult (18-24 years of age) subjects and between citalopram/escitalopram vs other SSRIs. RESULTS: During the study period, 237 eligible cases were identified with 2370 matched controls. Cases were more likely to have government insurance and have a mental health, cardiac, or other complex chronic condition. Thirteen cases (5%) and 15 controls (<1%) had current SSRI exposure. After adjustment for mental health and chronic conditions, there was an increased odds of current SSRI use among cases compared with controls (OR 5.11, 95% CI 1.22-21.37). No difference was observed between pediatric and young adult ages, nor between citalopram/escitalopram and other SSRIs. CONCLUSIONS: These findings demonstrate increased odds of out-of-hospital ventricular arrhythmia associated with SSRI use in the pediatric and young adult population, suggesting a need for heightened awareness and ongoing monitoring of this potential adverse effect.

Opioid Prescribing After Discharge in a Previously Mechanically Ventilated, Opioid-Naïve Cohort.

BACKGROUND: Opioids are utilized for pain management during and after mechanical ventilation in the intensive care unit (ICU). OBJECTIVE: The purpose of this study was to determine the percentage of potentially unnecessary opioid prescriptions on discharge in previously opioid-naïve patients. METHODS: This retrospective cohort study included mechanically ventilated, opioid-naïve ICU patients who received opioids. The primary outcome of this study was the discrepancy between the amounts of opioids prescribed at discharge versus those likely required based on actual 24-hour prehospital discharge opioid requirements. RESULTS: A total of 71 patients were included. Of these, 63.3% (n = 45) of discharge prescriptions were in alignment with 24-hour predischarge requirements, and 36.7% (n = 26) of discharge prescriptions were in excess of calculated predischarge requirements. At discharge, 57.7% (n = 41) of patients received a nonopioid analgesic. Multivariable linear regression revealed that cardiothoracic ICU admission was associated with an increased risk of inappropriate discharge opioid prescribing, whereas a shorter duration of inpatient oral opioid therapy decreased risk of inappropriate discharge prescribing. CONCLUSION AND RELEVANCE: Opioid prescribing for previously mechanically ventilated patients warrants improvement as a part of the discharge planning process. Application of these data may aid in the reduction of opioid overprescribing at discharge after an ICU stay.

Validity of administrative claims-based algorithms for ventricular arrhythmia and cardiac arrest in the pediatric population.

PURPOSE: Identify administrative claims-based algorithms for capturing out-of-hospital ventricular arrhythmias (VA) and cardiac arrests (CA) due to cardiac causes in the pediatric population with high positive-predictive value (PPV). METHODS: Within a single pediatric center, a retrospective cohort of patients hospitalized or seen in the emergency room for VA or CA were identified from the electronic health records. Eligible encounters were blindly reviewed and linked to administrative data, including ICD-9/ICD-10 codes. Test characteristics, including PPV, for different diagnostic and procedure codes were generated using a 50% training sample. The gold standard was definite or suspected out-of-hospital VA or CA due to cardiac cause verified based on clinical criteria. Algorithms with the highest PPV were then applied to a 50% validation sample to validate performance. RESULTS: From 2004-2017, 598 encounters met eligibility criteria. 174 (29%) had an outcome of interest, with remainder being an inpatient event or CA due to other cause. Within the training sample (n = 263), VA codes in primary position had a PPV 94% (95%CI 81%-99%) with low sensitivity (44%, 95%CI 33%-56%). CA codes in any position or VA codes in nonprimary positions had low PPV (18%-19%, 31% respectively). Applying the top three performing algorithms to the validation sample (n = 252) yielded similar PPV values. CONCLUSIONS: Contrary to adults, algorithms including a CA code do not perform well for identifying out-of-hospital VA and CA due to cardiac cause in the pediatric populations. Researchers should be aware of the potential implications for future pediatric drug safety studies for these outcomes.

Effects of a 3-Tier Pharmacy Benefit Design on the Prescription Purchasing Behavior of Individuals With Chronic Disease.

OBJECTIVE: To evaluate the impact of 3-tier (copayment) pharmacy benefit structures on medication utilization behavior. METHODS: A pretest-posttest quasi-experimental design was employed. Chronic disease sufferers (N=8,132) from a health plan were classified into the following groups: (a) 2-tier copayment moving to a 3-tier structure, ("converting" group), (b) 2-tier staying in a 2-tier structure and, (c) 3-tier staying in a 3-tier structure. The latter 2 were "comparison" groups. Two 7-month time periods were determined: the "preperiod" (June through December 2000) and the "postperiod" (January through July 2001) for a change in pharmacy benefit structure. Pharmacy claims data were used for data collection. Statistical analyses included bivariate tests to evaluate predifferences and postdifferences across study groups. Maximum likelihood estimates from a repeated measures model were used to examine changes in formulary compliance and generic use rates. Discontinuation of nonformulary medications was evaluated using logistic regression. RESULTS: Controlling for demographics, number of comorbidities, disease state, and pharmacy benefit structure, the formulary compliance rate increased by 5.6% for the converting group. No significant increases were seen for the comparison groups. Generic use rates increased by 6 to 8 absolute percentage points for all groups (3.3% to 4.9 % adjusted rates). Converting group members were 1.76 times more likely to discontinue their nonformulary medication than those in the 2-tier comparison group and 1.49 times more likely than those in the 3-tier comparison group. CONCLUSIONS: These findings suggest that shifting individuals from a 2-tier to a 3-tier drug benefit copayment structure resulted in changes in medication utilization. Decision makers need to balance these changes with the potential dissatisfaction that members may express in paying higher copayments. DISCLOSURES: Funding for this research was provided by Merck and Company through the Academic Medicine and Managed Care Forum and was obtained by authors Kavita V. Nair, Robert J. Valuck, Pamela Wolfe, Julie M. Ganther, and Marianne M. McCollum. Nair served as principal author of the study.

Alternatives to opioid protocols in Colorado emergency departments reduce opioid use without changing reported pain.

OBJECTIVE: The objective of this study was to determine whether instituting an alternative to opioids (ALTO) protocol significantly reduced opioid use in emergency departments (EDs). The secondary objective was to determine whether patient-reported pain and satisfaction were affected. METHODS: Electronic health records for 10 EDs in Colorado were retrospectively examined for the 6 months before the intervention and for the same 6 months the following year after the intervention, which consisted of systemic and educational initiatives in line with the Colorado American College of Emergency Physicians 2017 Opioid Prescribing and Treatment Guidelines. RESULTS: Of the total preintervention and postintervention unique patient visits, 47.2% received 1 of the drugs of interest, an opioid or ALTO, while in the ED. In aggregate, the EDs decreased opioid usage, measured in morphine equivalent units per 1000 ED visits, by 37.4% (95% confidence interval, 33.6%-76.2%; P < 0.0001) after the intervention. Statistically significant decreases were seen in every type of opioid. Statistically significant increases in ALTO usage were also noted across all study hospitals. There were no significant changes observed in Hospital Consumer Assessment of Healthcare Providers and Systems patient satisfaction scores before and after the intervention in the hospitals with Hospital Consumer Assessment of Healthcare Providers and Systems data (preintervention mean, 3.74; postintervention mean, 3.74; P = 0.637), and there was a small but statistically significant improvement in pain scores (preintervention mean, 3.62; postintervention mean, 3.66; P = 0.002). In a subgroup analysis of patients presenting with chief complaints of long bone fractures and malignant neoplasms, there were no significant reductions in opioid use. CONCLUSIONS: This study demonstrated the feasibility and effectiveness of implementing ALTO protocols to reduce opioid use in the ED setting without an overall reduction in patient perception of pain or satisfaction with care.

Access to Psychotropic Medication via Prescription Is Associated With Choice of Psychotropic Medication as Suicide Method: A Retrospective Study of 27,876 Suicide Attempts.

OBJECTIVE: Whether physical access to psychotropic medication via prescription (ie, prescribed access) is associated with use of psychotropic medication as a means of subsequent suicide attempt remains unclear. In a population of suicide attempters, we investigated whether prescribed access to any psychotropic medication increased the likelihood of using any psychotropic drug in a suicide attempt and whether prescribed access to a specific psychotropic drug type increased the likelihood of using that specific psychotropic drug type in an attempt. METHODS: Case-control study design was used. We identified individuals receiving care for a suicide attempt (fatal or nonfatal) in emergency department and inpatient settings from a US insurance claims dataset (2006-2013) using relevant ICD-9-CM codes. Cases used a psychotropic drug in their suicide attempt, while controls used another method. Exposed individuals filled a psychotropic drug prescription within 90 days prior to the attempt. Multivariable logistic regression estimated odds ratios. RESULTS: A population of 27,876 (cases = 10,158, controls = 17,718) was included. Anxiolytics were used most in attempts (n = 6,037, 59.4%), followed by antidepressants (n = 3,573, 35.2%), antipsychotics or mood stabilizers (n = 1,168, 11.5%), and stimulants (n = 368, 3.6%). Thirteen percent (n = 1,316) used more than 1 type of psychotropic drug in the attempt. Across all psychotropic drug groups evaluated, individuals using psychotropic medication in a suicide attempt were significantly more likely to have had prescribed access (adjusted odds ratio [aOR] = 1.7; 95% CI, 1.6-1.9), with the highest drug type-specific odds ratios for antipsychotics or mood stabilizers (aOR = 6.5; 95% CI, 5.4-7.7) and stimulants (aOR = 7.6; 95% CI, 5.5-10.5). CONCLUSIONS: Individuals at high risk for suicide with prescribed access to any psychotropic medication should be targeted for means safety interventions.

Survey of Nonprescription Medication and Antibiotic Use in Patients with Stevens-Johnson Syndrome, Toxic Epidermal Necrolysis, and Overlap Syndrome.

Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and overlap syndrome (SJS-TEN) are rare, serious skin and mucosa break-down conditions frequently associated with antibiotic use. The role of nonprescription medications alone, or in combination with antibiotics in triggering SJS/TEN, is largely unknown. This study summarized data collected from patient surveys about nonprescription and antibiotic use prior to a SJS/TEN diagnosis. The survey was administered online to members of the U.S. SJS Foundation who had been diagnosed with SJS/TEN or were the parent of a child who had been diagnosed with SJS/TEN. Respondents were asked about nonprescription medications taken within the year before diagnosis, and the approximate point in time before diagnosis that they had taken them. They were also asked about specific prescription medications, including antibiotics, that they took before diagnosis. An estimated 4500 patients received an invitation to complete the survey. 251 patients completed it, resulting in a response rate of 5.6%. The mean age of respondents was 43 years (SD (standard deviation) = 17.3) and 70% were female. 32.3% of respondents indicated that a prescription antibiotic triggered their reaction. 14.1% indicated a nonprescription medication had triggered their SJS/TEN, and 18.1% said a nonprescription medication may have triggered their SJS/TEN. 85.5% of respondents said they took a nonprescription medication within three months of their SJS/TEN diagnosis. Of those respondents who reported that an antibiotic triggered their SJS/TEN, 35.2% reported taking a nonprescription medication within the three months prior to their diagnosis. This survey captured valuable information about nonprescription and antibiotic use in SJS/TEN patients. It is important for future studies to estimate the impact of antibiotics on SJS/TEN, and account for nonprescription medication use in that relationship.

Assessing and predicting drug-induced anticholinergic risks: an integrated computational approach.

BACKGROUND: Anticholinergic (AC) adverse drug events (ADEs) are caused by inhibition of muscarinic receptors as a result of designated or off-target drug-receptor interactions. In practice, AC toxicity is assessed primarily based on clinician experience. The goal of this study was to evaluate a novel concept of integrating big pharmacological and healthcare data to assess clinical AC toxicity risks. METHODS: AC toxicity scores (ATSs) were computed using drug-receptor inhibitions identified through pharmacological data screening. A longitudinal retrospective cohort study using medical claims data was performed to quantify AC clinical risks. ATS was compared with two previously reported toxicity measures. A quantitative structure-activity relationship (QSAR) model was established for rapid assessment and prediction of AC clinical risks. RESULTS: A total of 25 common medications, and 575,228 exposed and unexposed patients were analyzed. Our data indicated that ATS is more consistent with the trend of AC outcomes than other toxicity methods. Incorporating drug pharmacokinetic parameters to ATS yielded a QSAR model with excellent correlation to AC incident rate (R2 = 0.83) and predictive performance (cross validation Q2 = 0.64). Good correlation and predictive performance (R2 = 0.68/Q2 = 0.29) were also obtained for an M2 receptor-specific QSAR model and tachycardia, an M2 receptor-specific ADE. CONCLUSIONS: Albeit using a small medication sample size, our pilot data demonstrated the potential and feasibility of a new computational AC toxicity scoring approach driven by underlying pharmacology and big data analytics. Follow-up work is under way to further develop the ATS scoring approach and clinical toxicity predictive model using a large number of medications and clinical parameters.

Using clinical data to predict high-cost performance coding issues associated with pressure ulcers: a multilevel cohort model.

OBJECTIVE: Hospital-acquired pressure ulcers (HAPUs) have a mortality rate of 11.6%, are costly to treat, and result in Medicare reimbursement penalties. Medicare codes HAPUs according to Agency for Healthcare Research and Quality Patient-Safety Indicator 3 (PSI-03), but they are sometimes inappropriately coded. The objective is to use electronic health records to predict pressure ulcers and to identify coding issues leading to penalties. MATERIALS AND METHODS: We evaluated all hospitalized patient electronic medical records at an academic medical center data repository between 2011 and 2014. These data contained patient encounter level demographic variables, diagnoses, prescription drugs, and provider orders. HAPUs were defined by PSI-03: stages III, IV, or unstageable pressure ulcers not present on admission as a secondary diagnosis, excluding cases of paralysis. Random forests reduced data dimensionality. Multilevel logistic regression of patient encounters evaluated associations between covariates and HAPU incidence. RESULTS: The approach produced a sample population of 21 153 patients with 1549 PSI-03 cases. The greatest odds ratio (OR) of HAPU incidence was among patients diagnosed with spinal cord injury (ICD-9 907.2: OR = 14.3; P < .001), and 71% of spinal cord injuries were not properly coded for paralysis, leading to a PSI-03 flag. Other high ORs included bed confinement (ICD-9 V49.84: OR = 3.1, P < .001) and provider-ordered pre-albumin lab (OR = 2.5, P < .001). DISCUSSION: This analysis identifies spinal cord injuries as high risk for HAPUs and as being often inappropriately coded without paralysis, leading to PSI-03 flags. The resulting statistical model can be tested to predict HAPUs during hospitalization. CONCLUSION: Inappropriate coding of conditions leads to poor hospital performance measures and Medicare reimbursement penalties.

The use of the Psychiatric Electroencephalography Evaluation Registry (PEER) to personalize pharmacotherapy.

PURPOSE: This study aims to determine whether Psychiatric Electroencephalography Evaluation Registry (PEER) Interactive (an objective, adjunctive tool based on a comparison of a quantitative electroencephalogram to an existing registry of patient outcomes) is more effective than the current standard of care in treatment of subjects suffering from depression. PATIENTS AND METHODS: This is an interim report of an ongoing, 2-year prospective, randomized, double blind, controlled study to evaluate PEER Interactive in guiding medication selection in subjects with a primary diagnosis of depression vs standard treatment. Subjects in treatment at two military hospitals were blinded as to study group assignment and their self-report symptom ratings were also blinded. Quick Inventory of Depressive Symptomatology, Self-Report (QIDS-SR16) depression scores were the primary efficacy endpoint. One hundred and fifty subjects received a quantitative electroencephalography exam and were randomized to either treatment as usual or PEER-informed pharmacotherapy. Subjects in the control group were treated according to Veterans Administration/Department of Defense Guidelines, the current standard of care. In the experimental group, the attending physician received a PEER report ranking the subject's likely clinical response to on-label medications. RESULTS: In this post hoc interim analysis subjects were separated into Report Followed and Report Not Followed groups - based on the concordance between their subsequent treatment and PEER medication guidance. We thus evaluated the predictive validity of PEER recommendations. We found significantly greater improvements in depression scores (QIDS-SR16 P<0.03), reduction in suicidal ideation (Concise Health Risk Tracking Scale-SR7 P<0.002), and post-traumatic stress disorder (PTSD) score improvement (PTSD Checklist Military/Civilian P<0.04) for subjects treated with PEER-recommended medications compared to those who did not follow PEER recommendations. CONCLUSION: This interim analysis suggests that an objective tool such as PEER Interactive can help improve medication selection. Consistent with results of earlier studies, it supports the hypothesis that PEER-guided treatment offers distinct advantages over the current standard of care.

Are Evidence-based Practices Associated With Effective Prevention of Hospital-acquired Pressure Ulcers in US Academic Medical Centers?

BACKGROUND: In 2008, the Centers for Medicare and Medicaid Services (CMS) established nonpayment policies resulting from costliness of hospital-acquired pressure ulcers (HAPUs) to hospitals. This prompted hospitals to adopt quality improvement (QI) interventions that increase use of evidence-based practices (EBPs) for HAPU prevention. OBJECTIVE: To evaluate the longitudinal impact of CMS policy and QI adoption on HAPU rates. MATERIALS AND METHODS: We characterized longitudinal adoption of 25 QI interventions that support EBPs through hospital leadership, staff, information technology, and performance and improvement. Quarterly counts of HAPU incidence and inpatient characteristics were collected from 55 University HealthSystem Consortium hospitals between 2007 and 2012. Mixed-effects regression models tested the longitudinal association of CMS policy, HAPU coding, and QI on HAPU rates. The models assumed level-2 random intercepts and random effects for CMS policy and EBP implementation to account for between-hospital variability in HAPU incidence. RESULTS: Controlling for all 25 QI interventions, specific updates to EBPs for HAPU prevention had a significant, though modest reduction on HAPU rates (-1.86 cases/quarter; P=0.002) and the effect of CMS nonpayment policy on HAPU prevention was much greater (-11.32 cases/quarter; P<0.001). CONCLUSIONS: HAPU rates were significantly lower after changes in CMS reimbursement. Reductions are associated with hospital-wide implementation of EBPs for HAPU prevention. Given that administrative data were used, it remains unknown whether these improvements were due to changes in coding or improved quality of care.

Multiple sclerosis prevalence in the United States commercially insured population.

OBJECTIVE: To estimate the US commercially insured multiple sclerosis (MS) annual prevalence from 2008 to 2012. METHODS: The study was a retrospective analysis using PharMetrics Plus, a nationwide claims database for over 42 million covered US representative lives. Annual point prevalence required insurance eligibility during an entire year. Our primary annual MS identification algorithm required 2 inpatient claims coded ICD-9 340 or 3 outpatient claims coded ICD-9 340 or 1 MS-indicated disease-modifying therapy claim. Age-adjusted annual prevalence estimates were extrapolated to the US population using US Census data. RESULTS: The 2012 MS prevalence was 149.2 per 100,000 individuals (95% confidence interval 147.6-150.9). Prevalence was consistent over 2008-2012. Female participants were 3.13 times more likely to have MS. The highest prevalence was in participants aged 45-49 years (303.5 per 100,000 individuals [295.6-311.5]). The East Census region recorded the highest prevalence (192.1 [188.2-196.0]); the West Census region recorded the lowest prevalence (110.7 [105.5-116.0]). The US annual 2012 MS extrapolated population was 403,630 (387,445-419,833). CONCLUSIONS: MS prevalence rates from a representative commercially insured database were higher than or consistent with prior US estimates. For further accuracy improvement of US prevalence estimates, results should be confirmed after validation of MS identification algorithms, and should be expanded to other US populations, including the government-insured and the uninsured.

Comparison of antidepressant classes and the risk and time course of suicide attempts in adults: propensity matched, retrospective cohort study.

BACKGROUND: Placebo-controlled clinical trials have led to concern over possible increased risk of suicide-related events in some populations exposed to antidepressants. AIMS: To evaluate the risk of suicide attempts by antidepressant drug class and the presence or absence of depression. METHOD: A retrospective propensity-matched new-user cohort study was used to compare participants with incident depression classified by antidepressant treatment with each other and with the general population. RESULTS: Among the treated group, the suicide attempt rate peaked in the month prior to diagnosis then decreased steadily over the next 6 months. Among the pharmacologically untreated group, the highest rate was seen in the second month after diagnosis. Cohorts with depression had significantly higher suicide attempt risk than the general population, but the treated group did not differ significantly from the untreated group. CONCLUSIONS: Patients on antidepressants did not have significantly higher risk compared with untreated patients. No significant differences were observed for patients treated with individual serotonin-noradrenaline reuptake inhibitors (SNRIs) or selective serotonin reuptake inhibitors (SSRIs) or by class (SSRI v. SNRI cohorts).

Increased Adoption of Quality Improvement Interventions to Implement Evidence-Based Practices for Pressure Ulcer Prevention in U.S. Academic Medical Centers.

OBJECTIVE: In 2008, the U.S. Centers for Medicare and Medicaid Services enacted a nonpayment policy for stage III and IV hospital-acquired pressure ulcers (HAPUs), which incentivized hospitals to improve prevention efforts. In response, hospitals looked for ways to support implementation of evidence-based practices for HAPU prevention, such as adoption of quality improvement (QI) interventions. The objective of this study was to quantify adoption patterns of QI interventions for supporting evidence-based practices for HAPU prevention. METHODS: This study surveyed wound care specialists working at hospitals within the University HealthSystem Consortium. A questionnaire was used to retrospectively describe QI adoption patterns according to 25 HAPU-specific QI interventions into four domains: leadership, staff, information technology (IT), and performance and improvement. Respondents indicated QI interventions implemented between 2007 and 2012 to the nearest quarter and year. Descriptive statistics defined patterns of QI adoption. A t-test and statistical process control chart established statistically significant increase in adoption following nonpayment policy enactment in October 2008. Increase are described in terms of scope (number of QI domains employed) and scale (number of QI interventions within domains). RESULTS: Fifty-three of the 55 hospitals surveyed reported implementing QI interventions for HAPU prevention. Leadership interventions were most frequent, increasing in scope from 40% to 63% between 2008 and 2012; "annual programs to promote pressure ulcer prevention" showed the greatest increase in scale. Staff interventions increased in scope from 32% to 53%; "frequent consult driven huddles" showed the greatest increase in scale. IT interventions increased in scope from 31% to 55%. Performance and improvement interventions increased in scope from 18% to 40%, with "new skin care products . . ." increasing the most. LINKING EVIDENCE TO ACTION: Academic medical centers increased adoption of QI interventions following changes in nonpayment policy. These QI interventions supported adherence to implementation of pressure ulcer prevention protocols. Changes in payment policies for prevention are effective in QI efforts.

The depth, duration, and degree of outpatient pediatric polypharmacy in Colorado fee-for-service Medicaid patients.

BACKGROUND AND OBJECTIVES: Outpatient pediatric polypharmacy is poorly characterized. Identification of at-risk populations has clinical implications for pharmacy case management programs. We described the degree of exposure to polypharmacy using parameters of depth (concurrent medication count) and duration, reported commonly dispensed medications and exposure to three example potential drug-drug interactions by different depths of polypharmacy, and determined patient characteristics associated with exposure to increased degrees (a function of depth and duration) of polypharmacy. METHODS: Retrospective cohort study of Colorado fee-for-service Medicaid patients aged <18 years with 12 months of continuous enrollment. We calculated depth of polypharmacy using daily concurrent medication counts and duration of polypharmacy using days exposed to a certain depth. Multinomial logistic regression was used to assess patient characteristics associated with different degrees of polypharmacy. RESULTS: Of 242 230 patients, 35% percent were exposed to any depth of polypharmacy, most commonly to anti-infective medications. Patients with higher depth polypharmacy were exposed to less common medications (psychotropic drugs, anticonvulsants, cardiovascular agents, and opioids) and to higher rates of exposure to potential drug-drug interactions. Of 47 972 patients exposed to ≥3 concurrent medications, 50% were exposed for <15 days, 25% for 15-38 days, 15% for 39-111 days, and 10% for 112-327 days. High-degree polypharmacy was associated with increasing age, male gender, and presence of a complex chronic condition. CONCLUSIONS: Outpatient pediatric polypharmacy occurs to a substantial degree for a small but vulnerable population of children, who may be candidates for pharmacy case management. We must determine whether increased exposure to high-degree polypharmacy causes harm.

Patterns of Off-Label Prescribing in the Pediatric Intensive Care Unit and Prioritizing Future Research.

OBJECTIVES: To characterize off-label prescribing among US pediatric intensive care units (PICUs), determine characteristics associated with off-label use, and identify medications in highest need for additional study. METHODS: Medications prescribed for ≥1% PICU patients (age < 18 years) in 2010 were identified from 39 children's hospitals. Use in a patient younger than the Food and Drug Administration (FDA)-approved age for any indication was considered off-label. Hierarchical multivariable modeling was used to identify characteristics associated with off-label use, accounting for center effects. Highest-impact drugs were defined by: 1) high off-label use (off-label use in at least 5% of the PICU cohort), 2) high risk medication, and 3) high priority status by the FDA or Best Pharmaceuticals for Children Act (BPCA). RESULTS: A total of 66,896 patients received ≥1 medication of interest (n = 162) during their PICU stay. A median of 3 (interquartile range, 2-6) unique drugs per patient were used off-label. Those who received ≥1 drug off-label (85% of the cohort) had longer median PICU (2 days vs 1 day) and hospital (6 days vs 3 days) lengths of stay and higher mortality (3.6% vs 0.7%), p < 0.001. Factors independently associated with off-label drug use included: age 1 to 5 years, chronic conditions, acute organ failures, mechanical ventilation, arterial or venous catheters, dialysis, and blood products. Half of prescribed medications (n = 84) had been used off-label: 26 with significant off-label use, 30 high-risk medications, and 47 with high FDA/BPCA priority. The highest impact medications identified were: dexmedetomidine, dopamine, hydromorphone, ketamine, lorazepam, methadone, milrinone, and oxycodone. CONCLUSIONS: Most PICU patients are exposed to off-label medication use, with uncertain evidence. Future medication research in this population should focus on medications with high impact potential.
