Opioid Administration Disparities in Level I Trauma Center Adult Patients

Authors: Rosemary Nabaweesi, Jonathan Goree, Kevin Sexton, Brian Gittens

Abstract

Purpose of Study

In the US, opioids have caused significant morbidity and mortality over the last decade. In 2017 drug overdose accounted for 70,237 deaths and 67.7% of these involved an opioid. In 2016, the Centers for Disease Control and Prevention developed an opioid prescribing guideline with twelve recommendations for chronic pain management intended to improve communication between providers and patients, about opioid therapy safety and effectiveness and opioid use disorder risks.

Long-term opioid use typically begins with treatment of acute pain. Opioids can effectively relieve pain but judicious use should be taken to minimize the risk of abuse. Research indicates that 6% of patients have continued opioid use 90 days post-surgery, even though the length of initial opioid prescription directly correlates with chronic opioid use risk. Conversely, poorly controlled acute post-surgical pain increases rates of chronic post-surgical pain syndromes; thus adequately controlling acute pain is vital to preventing long-term opioid use.

Black and Latino patients are commonly prescribed less opioids than White patients for similar chief complaint and diagnosis. A retrospective review of pediatric emergency department admissions for appendicitis, found that White patients were twice as likely to be prescribed opioids compared to Black patients. Factors associated with racially disparate opioid-prescribing practices include implicit bias, provider patient communication gaps, lack of trust, historical trauma, lack of or limited healthcare access. In order to improve acute post-surgical pain management, decrease opioid use and eliminate prescribing disparities, many academic centers have developed standardized pain protocols. The pain protocols often include anesthetic plan standardization, acute pain regimens, and post-surgical opioid and adjuvant prescriptions. While literature demonstrates that the pain protocols have decreased peri-operative opioid prescription, there is a knowledge gap on the effect of pain protocols on improving opioid-prescribing racial disparities.

Aims

1) Identify opioid prescribing racial disparities among patients admitted to the trauma surgery service at a Level I Trauma Center
2) Determine the impact of implementing a standardized acute pain protocol intervention on identified prescribing disparities

Data and Methods

The trauma acute pain protocol to standardize opioid prescribing (ordering) was established mid-2017. We conducted a retrospective review of all adult trauma admissions at Level I trauma center between 2015 and 2018. Opioid prescription was our primary outcome for the logistic regression. Patients were matched for age, gender and injury severity. Eligibility criteria were adult patients admitted to a level I Trauma Center.

Key Findings

Of eligible patients, 7,581 met inclusion criteria, 5,115 pre-intervention and 2,466 post intervention. African American patients were significantly less likely to receive opioids than Caucasian patients after controlling for injury severity, age and gender; Odds ratio (OR) 0.61 95% Confidence Interval (CI) 0.49, 0.74; p-value <0.001. Similarly, Asian and Latino patients also were significantly less likely to receive opioids than Caucasian patients post intervention; OR 0.65, CI: 0.42, 0.98, p-value 0.042.

Submitted to GDI 12/16/2019

Implications

When trauma surgeons used a standardized acute pain protocol, the odds of African American, Asian and Latino patients being prescribed opioids following a traumatic event remained lower compared to Caucasian patients with matched injury severity, age and gender.

Next Steps

We posit that since prescribers adhered to the acute pain protocol, we have to examine the dispensation practices of nurses for as-needed medications. We propose to implement three educational interventions to mitigate the problem of disparate opioid dispensing and recommendation by nurses working with Trauma Surgery inpatients.

Tiny Pieces Matter: Caring for Children and Adolescents with DiGeorge Syndrome

Author: Whited, T.

Abstract

DiGeorge Syndrome, also referred to as 22q11.2 deletion syndrome, is the most common microdeletion syndrome in humans (Kuo, Signer & Saitta, 2018)  It affects ~ 1 in 2,000-4,000 live births worldwide (McDonald-McGinn, 2018). DiGeorge has variable phenotypic expression.  Multiple systems can be affected including the heart, genitourinary tract, thymus, parthyroid, palate, and musculoskeletal systems (Sullivan, 2019).  Patients with DiGeorge syndrome can have developmental delays, learning disabilities, and psychiatric illness (Batavia et al., 2019). 

 Due the variable expression of DiGeorge Syndrome, the patient should have appropriate work up, diagnosis and management to allow them to reach their full potential.  The literature has identified multiple interventions for the diagnosis and care of these special children including management of heart disease, developmental screenings, early intervention, management of immunodeficiencies, and long term care (McDonald-McGinn, 2018; Sullivan, 2019; Swillen & McDonald-McGinn, 2015).     

This interactive session using the audience response system will assist providers in identifying the latest recommendations related to DiGeorge Syndrome.  The session will discuss the key components in caring for children with DiGeorge Syndrome and ways to maximize their potential.  Finally, the session will focus on the nurse practitioners role in caring for children and adolescents with DiGeorge Syndrome. Pediatric Nurse Practitioners need to be prepared to care for these challenging but wonderful patients.

Abstract

Background: Attainment of MRD negativity in multiple myeloma (MM) patients is increasingly considered an optimal therapeutic endpoint, but little is known about the MRD evolution in those who achieve this milestone. We investigated the clinical implication of loss of MRD negativity or MRD conversion in patients with ≥VGPR.

Methods: We identified and followed 606 patients achieving a sustained ≥VGPR with bone marrow MRD negativity(≥ 2 consecutive reading) following treatment on a total therapy protocol and with a median follow-up of 10 y. All patient had negative PET and MRI DWIBS at enrollment. Serial BM aspirate MRD was determined by 8- color next generation flow (NGF, EuroFlow) with a minimal sensitivity of 10-5 cells.

Results: Most MM patients were considered low risk with a UAMS GEP70 score of ≤ 0.66 (92%; 495/538) . While 60% (364/606) of patients had sustained MRD negativity, the remaining 40% (242/606) experienced MRD conversion with a 5.7 y median time from ASCT and 6.3 y from diagnosis. The risk of clinical relapse was significantly elevated in patients with MRD conversion compared to sustained MRD negativity (73%, 177/242 vs. 5%, 18/364; R.R. = 3.5; P < 0.0001). The median level of MRD positivity ( > 0.2 ratio of MM cells to normal plasma cells) also highly correlated with relapse (P< 0.0001). Loss of MRD negativity preceded clinical relapse by a median time of 1.1 years. Loss of MRD negativity without clinical relapse was seen in 27% (65/242). MRD conversion was associated with an inferior PFS and OS (PFS: 10.2 y vs. NR; P < 0.0001, H.R. 18.7; 95% CI 13.3 – 26.3 and OS: 26.1 y vs. NR; P = 0.01, H.R. 1.7; 95% CI 1.1 – 2.6). Furthermore, when MRD conversion was within 5 y of diagnosis compared > 5 y, patients had a worse OS (P < 0.0001, H.R. 17.2; 95% CI 7.8 – 37.8). We also observed that MRD conversion later than 5 years from diagnosis did not affect the OS. In a subset of patients (n = 144) the timing of first MRD negativity following treatment was available. Attainment of MRD negativity within 6 months of diagnosis compared to any time after 6 (https://asco.confex.com/asco/2020/sci/papers/index.cgi?username=299013&password=*cookie) 1/6 months was predictive of future MRD conversion (65%, 17/26 vs. 42%, 49/118; P = 0.03) and clinical relapse (54%, 14/26 vs. 28%, 33/118; P = 0.02).

Conclusions: MRD conversion occurs in a significant proportion of MM patients (40%) on long-term follow-up and predicts future clinical relapse. Significance of MRD conversion has a temporal relationship from diagnosis and portray inferior clinical outcome particularly within 5 years of diagnosis.

Impact of Neuromodulation on Gait Speed in Alzheimer’s Dementia

Authors: Kalpana P. Padala, Shelly Lensing, Christopher Parkes, Kim Dean, Lillian Orr, Tracy Holder, Prasad R. Padala

Abstract

Background: Alzheimer’s Dementia (AD) is a major public health problem. Although the cognitive symptoms of AD garner the most attention, non-cognitive symptoms such as neuropsychiatric symptoms (NPS) and motor abnormalities contribute most to the functional decline seen in AD. Unfortunately, both NPS and gait and balance problems are common in AD and may share a common neurobiological etiology. Repetitive transcranial magnetic stimulation (rTMS), a non-invasive neuromodulation technique with the potential to enhance dopamine, is used to improve NPS particularly apathy. The objective was to study the effects of rTMS to the dorsolateral prefrontal cortex (DLPFC) on gait speed in AD.

Methods: A prospective randomized double-blind sham-controlled study was conducted in community dwelling older Veterans (N=20) with AD and apathy. Subjects received rTMS or sham treatments daily for four weeks for a total of 20 treatments. Treatment parameters were set at 10Hz stimulation, 120% Motor threshold (MT), and 3000 pulses per treatment although MT was lowered if necessary. Gait speed was assessed at baseline and 4 weeks.

Results: All subjects except one completed the study. Mean age was 77.3 (±7.2) years, 80% were Caucasian and 10% were female. After adjusting for baseline, there was a significantly greater improvement from baseline in the gait speed with rTMS treatment compared to sham treatment after four weeks of treatment (average between-group difference 0.10, (95% CI, 0.05-0.14) m/s, p<0.001). Treatment site discomfort was the most common adverse event.

Conclusions: rTMS may be used safely in patients with AD and may improve gait speed. Improved gait speed enhances physical function and decreases risk of falls, which may result in improved survival.

A Comparison of Methylphenidate and Placebo Effects on Cardiac Function in the Elderly Population with Mild Alzheimer’s Disease

Authors: Paul Parcon, M.D., Ph.D.; C. Heath Gauss, M.S.; Kalpana Padala, M.D.; Prasad Padala, M.D.

Abstract

Background: Apathy in Alzheimer’s disease (AD) is increasingly being recognized as a separate and distinct clinical syndrome from depression and has an out-sized effect on caregiver burden and quality of life. Evidence shows methylphenidate is an effective treatment for this condition, but fears regarding cardiovascular effects of methylphenidate (MPH) in the elderly have limited its widespread use. This project sought to assess the differences in EKG time variables and interpretation collected from an RCT for apathy in mild AD, comparing methylphenidate to placebo.

Methods: We used data from cohort of 59 community-dwelling patients with mild AD (30 from MPH arm, 29 from placebo arm) obtained from a randomized controlled trial. EKG data collected at baseline, 4 weeks, and 12 weeks was analyzed for changes from baseline for PR interval, QRS interval, and QT/QTc interval via repeated measures mixed model analyses of covariance. The predictor variables in each model were arm, time, the interaction between arm and time, and the baseline value of the EKG time variable of interest. The two arms were compared with respect to changes from baseline to 4 weeks and to 12 weeks using model-based t tests. Also, EKG interpretations were assessed in the analyses.

Results: No statistical difference was found between the two arms regarding changes from baseline to 4 weeks for any of the EKG time intervals considered. For changes from baseline to 12 weeks, no statistical difference was found except for P (+11.7 MPH vs. placebo, p=0.0492) and T (+15.4, p=0.0437). Although no cardiovascular adverse events were reported by patients, in terms of the changes in EKG interpretations, 3 patients in the MPH arm showed EKG changes, while 7 were seen in the placebo arm. Two patients in the MPH arm demonstrated new septal infarcts, and one showed QT prolongation at 4 weeks (but not at 12 weeks). Of the 7 changes in the placebo arm, there was one new inferior infarct, 2 new LBBBs, one new RBBB, and one possible anterior infarct. Also in the placebo arm, there was one change from possible infarct to confirmed, and one instance of QT Prolongation at 4 weeks (but not at 12 weeks).

Conclusions: Our results demonstrate that over the trial period, no statistical difference was found in the EKG time intervals of patients randomized either to MPH or placebo group. Further, the changes in the EKG interpretations favored the MPH over the placebo group. These results may bolster the data on safety of MPH in apathetic elders, and hopefully will lead to more widespread use.

Hybrid Cord Blood Banks May Be Advantageous For Scientific As Well As Economic Reasons

Authors: Soumya Pandey, Plummer Badger, Michele Cottler-Fox

Abstract:

Public cord blood banks have thresholds for accepting cord blood collections for processing based on economic models developed using surrogate markers of suitability, i.e. volume and total nucleated cell count (TNCC). Only after processing has it been possible to look at CD34+ cell numbers and Colony forming unit (CFU).

Since as few as 0.52 x105 CD34+ cells can be expanded in vitro and used successfully for transplant (Lancet Haematol on line Nov 5, 2019; doi.org/10.1016/S2352- 3026(19)30202-9), it is important to understand what is in the smaller collections that public bank guidelines currently prevent from being processed. Hybrid public/private cord blood banks permit economic support from the private bank to help support the public bank. They also offer an opportunity to evaluate products outside public banking thresholds because all collections are processed. Here we present data from the first 72 private cord blood unit (CBU) collections processed for the Cord Blood Bank of Arkansas, showing the relationship between collection volume, TNCC and CD34+ cell numbers.

The influence of knee flexion angle on sagittal spinopelvic alignment in patients with knee osteoarthritis.

Authors: Ryota Katsumi, Jeffrey B Stambough, Simon C. Mears, Paul Edwards, C.Lowry Barnes, Erin M.Mannen

Abstract:

INTRODUCTION: Abnormal spinopelvic alignment in the sagittal plane is thought to contribute to the sagittal imbalance and the pathogenesis of chronic low back pain. Knee flexion is proposed as a compensatory mechanism in cases of sagittal imbalance. In contrast, the malalignment of the osteoarthritic knee might contribute to abnormal spinopelvic alignment in the sagittal plane. The purpose of this retrospective study was to assess the relationship between knee flexion angle (KFA) and sagittal spinopelvic alignment parameters of patients with end-stage knee osteoarthritis in a weight-bearing standing position using a low-dose biplanar imaging system.

METHODS: According to a priori power analysis (G*Power 3.1; Institut fur Experimentaelle Psychologie, Dusseldorf, Germany), 84 patients with end-stage knee osteoarthritis and no history of severe spinal deformity, spinal fracture, or spinal surgery (33 male, 51 female, average age 65) underwent anteroposterior and lateral standing x-rays (EOS imaging). Sagittal alignment parameters were measured: thoracic kyphosis (TK), lumbar lordosis (LL), sagittal pelvic tilt (PT), sagittal vertical axis (SVA) and KFA (Figure 1). TK and LL were the angles between the superior endplate of T4 and the inferior endplate of T12, and the superior endplate of L1 and the endplate of S1, respectively. PT was the angle between the vertical and the line through the midpoint of the sacral plate to femoral head axis. SVA was the distance between C7 plumb line and posterior edge of sacral plate. KFA was the angle between the femoral axis and the tibial axis. The correlations between KFA and TK, LL, PT, SVA were evaluated using the Spearman’s rank-order correlation coefficient (rs). The probability level accepted for statistical significance was set to p < 0.05 (SPSS version 24; SPSS, Inc., Chicago, IL, USA).

RESULTS: The mean value, standard deviation, and range of each parameter are shown in Table 1. TK, LL, PT, SVA, KFA were 43.1°±13.5°, 52.2°±10.7°, 16.1°±8.6°, 31.3±34.1 mm, and 10.0°±9.4°, respectively. Significant correlations between KFA and LL (rs = -0.222, p = 0.042), and KFA and SVA (rs = 0.417, p < 0.001) were found. There were no significant correlations between KFA and TK or PT.

DISCUSSION AND CONCLUSION: The sagittal spinopelvic alignment was significantly influenced by KFA in patients with end-stage knee osteoarthritis. The more flexed knee led to reduced LL and larger SVA. According to Murata et al., LL was significantly reduced in patients whose limitation of extension of the knee was more than 5°. Patients with larger SVA are reported to be usually imbalanced and have higher disability scores. The correction of the sagittal malalignment of the knee by realignment surgery such as total knee arthroplasty may improve the sagittal imbalance.

Diffuse Alveolar Hemorrhage in the Setting of Adenoviral Infection in an Immunocompetent Child.

Author: Matthew Pertzborn, Sanjiv Pasala, Mary Moore, Uday Chalwadi, Rasha M. Qaqish, Jordan Fett, Zena Ghazala, Erhan Ararat, Amit Agarwal, Ariel Berlinski

Abstract:

Introduction:
Diffuse alveolar hemorrhage (DAH) is a rare condition that can result from different etiologies. DAH has been associated with adenovirus infection in

12 immunocompromised patients . Acute DAH can be mitigated and recurrences of DAH can be prevented after systemic corticosteroid pulses . Use of intravenous 2 immunoglobulin (IVIG) has been attempted with variable reported results .

Case:
A 4 year old female was admitted to an outside hospital with a 1 day history of nasal congestion, cough, and increased work of breathing. Past history was significant for pulmonary tuberculosis at 2 years of age, which was treated per the family. Chest x-ray and computed tomography scan of the chest demonstrated patchy asymmetric alveolar opacities with prominent lung interstitium (Figure). Her hemoglobin was 2.4 grams/deciliter, for which she was given packed red blood cell transfusions (14 total during this illness).
Upon transfer to our institution, the exam was notable for tachypnea, accessory muscle use, and right lower lobe crackles without wheezes. She was intubated due to respiratory deterioration and bloody secretions were discovered. She required escalating positive end expiratory pressure (maximum 16 centimeters of water) to maintain oxygenation. Her lowest ratio of partial pressure of arterial oxygen to fractional inspired oxygen was 90 with an oxygenation index of 25.3. Respiratory viral polymerase chain reaction testing was adenovirus positive. Coagulation studies and echocardiogram were normal. An interferon gamma release assay for tuberculosis was not performed, but two respiratory acid-fast bacilli cultures (including one taken via deep endotracheal suctioning) were negative.
She completed a ceftriaxone course for empiric bacterial pneumonia coverage. She received two weekly 5 milligram/kilogram doses of cidofovir and three daily intravenous 30 milligram/kilogram methylprednisolone pulses. Her bloody secretions resolved, she was extubated, and she was discharged on room air 1 month after admission. She received a second course of intravenous methylprednisolone pulses and IVIG before discharge.
Discussion:
We report a rare case of diffuse alveolar hemorrhage in the setting of adenovirus respiratory infection in an immunocompetent patient. Though she clinically improved, we initiated monthly intravenous corticosteroid pulses and IVIG for a minimum of 12 months to prevent recurrence. This case is important because of the rare presentation with clinical improvement after administration of cidofovir and systemic corticosteroids.
