Role of Mitanin community health workers in improving complementary feeding practices under scaled-up home-based care of young children in a rural region of India.

BACKGROUND: A large proportion of young children in developing countries receive inadequate feeding and face frequent infections. Global research has established the need for improving feeding practices and management of child illnesses. Interventions involving home visits by community health workers (CHWs) for caregiver education have been attempted in many countries. Indian government rolled out an intervention called home-based care of young children (HBYC) in 2018 but no studies exist of its scaled-up implementation. The current study was aimed at assessing the coverage of HBYC in Chhattisgarh state where it has been implemented through 67,000 rural CHWs known as Mitanins. METHODS: This cross-sectional study was based on a primary household survey. Households with children in 7-36 months age were eligible for survey. A multi-stage sample of 2646 households was covered. Descriptive analyses were performed and key indicators were reported with 95% confidence intervals. To find out the association between caregiver practices and receiving advice from the CHWs, multivariate regression models were applied. RESULTS: Overall, 85.1% children in 7-36 months age received at least one home visit from a CHW within the preceding three months. Complementary feeding had been initiated for 67% of children at six months age and the rate was 87% at eight months age. Around one-third of the children were fed less than three times a day. Around 41% households added oil in child's food the preceding day. CHWs were contacted in 73%, 69% and 61% cases of diarrhea, fever and respiratory infections respectively in children. Among those contacting a CHW for diarrhea, 88% received oral rehydration. The adjusted models showed that receiving advice from CHWs was significantly associated with timely initiation of complementary feeding, increasing the frequency of feeding, increasing diet diversity, addition of oil, weighing and consumption of food received from government's supplementary nutrition programme. CONCLUSIONS: Along with improving food security of households, covering a large share of young children population with quality home visits under scaled-up CHW programmes can be the key to achieving improvements in complementary feeding and child care practices in developing countries.

Pediatric Croup Due to Omicron Infection Is More Severe Than Non-COVID Croup.

OBJECTIVE: Croup due to infection with the omicron variant of COVID is an emerging clinical entity, but distinguishing features of omicron croup have not yet been characterized. We designed a study to compare the clinical features of croup patients presenting to the pediatric emergency department pre-COVID pandemic with COVID-positive croup patients who presented during the initial omicron surge. METHODS: This was a retrospective observational cohort study of children 0 to 18 years old who presented to our urban, tertiary care pediatric emergency department with symptoms of croup. The study compared a cohort of croup patients who presented in the year before the onset of the COVID pandemic to a cohort of COVID-positive croup patients who presented during the initial omicron surge. The primary outcomes included illness severity and treatments required in the emergency department. The secondary outcome was hospital admission rate. RESULTS: There were 499 patients enrolled in the study, 88 in the omicron croup cohort and 411 in the classic croup cohort. Compared with the classic croup patients, omicron croup patients were more likely to present with stridor at rest (45.4% vs 31.4%; odds ratio [OR], 1.82; confidence interval [CI], 1.14-2.91) and hypoxia (3.4% vs 0.5%; OR, 7.22; CI, 1.19-43.86). Omicron croup patients required repeat dosing of inhaled epinephrine in the emergency department more often (20.4% vs 6.8%; OR, 3.51; CI, 1.85-6.70), and they were more likely to require respiratory support (9.1% vs 1.0%; OR, 10.18; CI, 2.99-34.60). Admission rates were significantly higher for omicron croup patients than for classic croup patients (22.7% vs 3.9%; OR, 7.26; CI, 3.58-14.71), and omicron croup patients required intensive care more frequently (5.7% vs 1.5%; OR, 4.07; CI, 1.21-13.64). CONCLUSIONS: Pediatric patients with omicron croup develop more severe disease than do children with classic croup. They are more likely to require additional emergency department treatments and hospital admission than patients with croup before the COVID pandemic.

Predicting Delayed Shock in Multisystem Inflammatory Disease in Children: A Multicenter Analysis From the New York City Tri-State Region.

OBJECTIVES: Patients with multisystem inflammatory disease in children (MIS-C) are at risk of developing shock. Our objectives were to determine independent predictors associated with development of delayed shock (≥3 hours from emergency department [ED] arrival) in patients with MIS-C and to derive a model predicting those at low risk for delayed shock. METHODS: We conducted a retrospective cross-sectional study of 22 pediatric EDs in the New York City tri-state area. We included patients meeting World Health Organization criteria for MIS-C and presented April 1 to June 30, 2020. Our main outcomes were to determine the association between clinical and laboratory factors to the development of delayed shock and to derive a laboratory-based prediction model based on identified independent predictors. RESULTS: Of 248 children with MIS-C, 87 (35%) had shock and 58 (66%) had delayed shock. A C-reactive protein (CRP) level greater than 20 mg/dL (adjusted odds ratio [aOR], 5.3; 95% confidence interval [CI], 2.4-12.1), lymphocyte percent less than 11% (aOR, 3.8; 95% CI, 1.7-8.6), and platelet count less than 220,000/uL (aOR, 4.2; 95% CI, 1.8-9.8) were independently associated with delayed shock. A prediction model including a CRP level less than 6 mg/dL, lymphocyte percent more than 20%, and platelet count more than 260,000/uL, categorized patients with MIS-C at low risk of developing delayed shock (sensitivity 93% [95% CI, 66-100], specificity 38% [95% CI, 22-55]). CONCLUSIONS: Serum CRP, lymphocyte percent, and platelet count differentiated children at higher and lower risk for developing delayed shock. Use of these data can stratify the risk of progression to shock in patients with MIS-C, providing situational awareness and helping guide their level of care.

Electronic Health Records as Biased Tools or Tools Against Bias: A Conceptual Model.

Policy Points Electronic health records (EHRs) are subject to the implicit bias of their designers, which risks perpetuating and amplifying that bias over time and across users. If left unchecked, the bias in the design of EHRs and the subsequent bias in EHR information will lead to disparities in clinical, organizational, and policy outcomes. Electronic health records can instead be designed to challenge the implicit bias of their users, but that is unlikely to happen unless incentivized through innovative policy. CONTEXT: Health care delivery is now inextricably linked to the use of electronic health records (EHRs), which exert considerable influence over providers, patients, and organizations. METHODS: This article offers a conceptual model showing how the design and subsequent use of EHRs can be subject to bias and can either encode and perpetuate systemic racism or be used to challenge it. Using structuration theory, the model demonstrates how a social structure, like an EHR, creates a cyclical relationship between the environment and people, either advancing or undermining important social values. FINDINGS: The model illustrates how the implicit bias of individuals, both developers and end-user clinical providers, influence the platform and its associated information. Biased information can then lead to inequitable outcomes in clinical care, organizational decisions, and public policy. The biased information also influences subsequent users, amplifying their own implicit biases and potentially compounding the level of bias in the information itself. The conceptual model is used to explain how this concern is fundamentally a matter of quality. Relying on the Donabedian model, it explains how elements of the EHR design (structure), use (process), and the ends for which it is used (outcome) can first be used to evaluate where bias may become embedded in the system itself, but then also identify opportunities to resist and actively challenge bias. CONCLUSIONS: Our conceptual model may be able to redefine and improve the value of technology to health by modifying EHRs to support more equitable data that can be used for better patient care and public policy. For EHRs to do this, further work is needed to develop measures that assess bias in structure, process, and outcome, as well as policies to persuade vendors and health systems to prioritize systemic equity as a core goal of EHRs.

Blink detection and magnetic force generation for correction of lagophthalmos, with specific regard to implant compatibility testing.

PURPOSE: The overall goal was to restore a normal and synchronous blink in unilateral lagophthalmos. We describe the biocompatibility profiling of a novel ferromagnetic implant used for electromagnetic eyelid force generation. METHODS: A non-contact blink detection system and an electromagnetic stimulation system were designed and tested. A modified Lester-Burch speculum equipped with strain gauge technology was used in blinking force measurement. Samarium-cobalt magnets were prototyped and coated with parylene-C. Biocompatibility testing was performed using NIH/3T3 mouse fibroblast cells with MTT colorimetric assay cytotoxic quantification. OUTCOME MEASURES: Cellular viability and interleukin concentrations. RESULTS: Our system was capable of detecting 95.5 ± 3.6% of blinks in various lighting conditions. Using our force measuring device, the difference between non-paralyzed and paralyzed orbicularis oculi (OO) for normal and forceful blinking closure was 40.4 g and 101.9 g, respectively. A 16.6 × 5.0 × 1.5 mm curved shaped samarium cobalt eyelid implant was successfully developed and showed a reproducible blink at 100 ms with full corneal coverage with external eyelid taping. Compared to gold weights, parylene-C coated samarium cobalt implants showed not only excellent cell viability (82.0 ± 4.9% vs. 88.4 ± 0.9%, respectively, p > .05), but also below detection threshold for pro-inflammatory marker concentrations (interleukin-6 < 2 pg/mL and interleukin-10 < 3 pg/mL). CONCLUSIONS: We demonstrated excellent in-vitro biocompatibility of our parylene-C coated samarium cobalt implants. We believe that our novel approach can improve the quality-of-life of affected individuals and provides new understanding of blinking biomechanics.

A designated trauma social worker improves coordination of patient care by coordinating ancillary consults.

Trauma patients face unique challenges that require coordination by social workers knowledgeable in the intricacies of trauma patient psychosocial support which is often achieved by obtaining ancillary consultations. The impact of employing a designated trauma social worker (DTSW) in the utilization of these consults has not been described. A retrospective review was conducted of trauma patients admitted to an academic, urban Level 1 trauma center. The pre-intervention cohort (n = 272) corresponded to patients admitted before the presence of a DTSW (01/2013 to 06/2013), while the post-intervention cohort (n = 282) corresponded to patients admitted afterward (09/2015 to 01/2016). Data collection included demographics, injury profile, and types of interdisciplinary or therapy consultations. Post-intervention patients were found to be older and admitted with more injuries. Supportive care, physical therapy and occupational therapy consultations were more likely to be obtained in the post-intervention cohort. Hospital length of stay remained unchanged. This study suggests that the implementation of a DTSW significantly facilitates the utilization of interdisciplinary consultations. Length of stay remains unchanged, suggesting that a DTSW helps to coordinate care in a timely manner without increasing the hospital stay. DTSW implementation may be considered in trauma centers where one does not currently exist.

Catheter-Directed Pharmacologic Thrombolysis for Acute Submassive and Massive Pulmonary Emboli in Children and Adolescents-An Exploratory Report.

OBJECTIVES: The objective of this study is to report a single-center experience of the safety and efficacy of pulmonary artery catheter-directed thrombolysis for both massive and submassive pulmonary emboli in the pediatric and adolescent population. DESIGN: A 22-month retrospective review of the electronic medical record and picture archiving and communication system was performed of patients less than 21 years old, presenting with massive or submassive pulmonary emboli treated with pulmonary artery catheter-directed thrombolysis at a single, tertiary care pediatric hospital. Multiple variables were analyzed including indications, technical success, clinical efficacy, and complications. SETTING: A single, tertiary care pediatric hospital. PATIENTS: Nine patients (mean 13.9 yr; range 6-19 yr) with massive and/or submassive pulmonary emboli who underwent pulmonary artery catheter-directed thrombolysis met inclusion criteria. INTERVENTIONS: Catheter-directed thrombolysis. MEASUREMENTS AND MAIN RESULTS: Pulmonary emboli was diagnosed by CT angiography in all cases. Catheter-directed thrombolysis alone was clinically successful (defined as improved cardiopulmonary function following catheter-directed thrombolysis) in seven patients (78%) with two patients not improving following catheter-directed thrombolysis. There were no immediate bleeding complications from catheter-directed thrombolysis therapy. All patients were maintained on anticoagulation treatment following catheter-directed thrombolysis. Catheter-directed thrombolysis was technically successful (defined as successful placement of pulmonary artery infusion catheters with full or partial resolution of thrombus) in all cases. Follow-up pulmonary angiography at the cessation of catheter-directed thrombolysis revealed complete thrombus resolution in four patients (44%) and partial resolution in five patients (55%). Mean pulmonary artery pressures decreased in all patients (mean precatheter-directed thrombolysis pulmonary artery pressure = 37 ± 11 mm Hg; mean postcatheter-directed thrombolysis pulmonary artery pressure = 28 ± 10 mm Hg; p = 0.0164). CONCLUSIONS: Pulmonary artery catheter-directed thrombolysis is a technically feasible therapeutic option for children and adolescents with submassive and massive pulmonary emboli.

Renal allograft loss due to renal vascular thrombosis in the US pediatric renal transplantation.

BACKGROUND: Renal vascular thrombosis (RVT) is a major cause of early allograft loss in the first year following pediatric kidney transplantation. We examined recent trends in allograft loss due to RVT and identified associated risk factors. METHODS: We identified 14,640 kidney-only transplants performed between 1995 and 2014 with follow-up until June 30, 2016, in 13,758 pediatric patients aged < 19 years from the US Renal Data System. We examined the 1-year incidence of allograft loss due to RVT by year of transplant, and plotted the trend over time. Cox proportional hazards models were used to investigate the relationship between year of transplant as well as recipient, donor, and transplant characteristics with allograft loss due to RVT. RESULTS: The incidence of allograft loss due to RVT consistently declined among pediatric kidney transplant performed between 1995 and 2014. Among transplants performed between 1995 and 2004, 128/7542 (1.7%) allografts were lost due to RVT compared to 53/7098 (0.8%) among transplants performed between 2005 and 2014; average 1-year cumulative incidence was 1.5% (95% CI, 1.3-1.9%) and 0.6% (95% CI, 0.5-0.8%), respectively. Increased risk for allograft loss due to RVT was associated with en bloc kidney transplantation (HR, 3.42; 95% CI 1.38-8.43) and cold ischemia time ≥ 12 h (HR, 1.78; 95% CI, 1.15-2.76). Interestingly, these risk factors were more prevalent in the latter decade. CONCLUSIONS: The incidence of allograft loss due to RVT significantly and continuously declined among pediatric kidney transplants performed between 1995 and 2014. The causes for this improvement are unclear in the present analysis.

Extended neuromuscular blockade in acute respiratory distress syndrome does not increase mortality.

BACKGROUND: Neuromuscular blockade (NMB) is often utilized in the treatment of acute respiratory distress syndrome (ARDS). Its use for a period of 48 h has been shown to improve mortality in randomized control trials. We aimed to characterize outcomes associated with a prolonged NMB. We hypothesized that the duration of NMB would not be associated with increased mortality. MATERIALS AND METHODS: This was a retrospective review from June 2014 to October 2016 of patients admitted to the surgical intensive care unit and receiving cisatracurium for ARDS. Patients paralyzed for ≤ 48 h (SHORT) were compared to those paralyzed for longer durations (LONG). Primary outcome was mortality. Parametric and nonparametric tests were utilized for the purposes of the comparison. A multivariate logistic regression model was utilized to adjust for differences. RESULTS: Of 73 patients meeting inclusion criteria, 32 (44%) were SHORT and 41 (56%) LONG. Compared to the LONG cohort, those in SHORT were older (60 versus 52 years, P = 0.04) but were comparable with respect to sex, acute physiology and chronic health evaluation IV scores, presence of concurrent pneumonia, and the use of vasopressors. SHORT patients were less likely to require rescue therapy with inhaled nitric oxide (28% versus 66%, P < 0.01). Overall mortality was 60%. There was no difference in the adjusted odds for mortality (adjusted odds ratio: 0.57, P = 0.33). Secondary outcomes including deep venous thrombosis and pneumonia did not differ between the two groups. CONCLUSIONS: Extended NMB for ARDS was not associated with increased mortality. Discontinuation of this modality should not be based solely on the duration of therapy.

The risk factors of venous thromboembolism in massively transfused patients.

BACKGROUND: Massive transfusion protocols (MTPs) are necessary for hemodynamically unstable trauma patients with active bleeding. Thrombotic events have been associated with blood transfusion; however, the risk factors for the development of venous thromboembolism (VTE) in trauma patients receiving MTP are unknown. METHODS: A retrospective review was conducted by reviewing the electronic medical records of all trauma patients admitted to a Level I trauma center who received MTP from 2011 to 2016. Data were collected on patient demographics, mechanism of injury, injury severity scores, quantity of blood products transfused during MTP activation, incidence of VTE, intensive care unit length of stay (LOS), hospital LOS, and ventilator days. The primary outcome was VTE. RESULTS: Of the 59 patients who had MTP activated, 15 (25.4%) developed a VTE during their hospital admission. Patients who developed VTE were compared with those who did not. Age (40 y versus 35 y, P = 0.59), sex (60% versus 73% male, P = 0.52), and mechanism of injury (47% versus 59% blunt, P = 0.40) were similar. Intensive care unit LOS, hospital LOS, and ventilator days were longer in the patients who were diagnosed with a VTE. Multivariable analysis revealed an increase in the odds for developing a VTE with increasing packed red blood cell transfusion (adjusted odds ratio = 2.61, P = 0.03). CONCLUSIONS: The risk for VTE in trauma patients requiring massive transfusion is proportional to the number of packed red blood cells transfused. Liberal screening protocols and maintenance of a high index of suspicion for VTE in these high-risk patients is justified.

The Additive Value of Pelvic Examinations to History in Predicting Sexually Transmitted Infections for Young Female Patients With Suspected Cervicitis or Pelvic Inflammatory Disease.

STUDY OBJECTIVE: We evaluate the additive value of pelvic examinations in predicting sexually transmitted infection for young female patients with suspected cervicitis or pelvic inflammatory disease in a pediatric emergency department (ED). METHODS: This was a prospective observational study of female patients aged 14 to 20 years who presented to an urban academic pediatric ED with a complaint of vaginal discharge or lower abdominal pain. Enrolled patients provided a urine sample for chlamydia, gonorrhea, and trichomonas testing, which served as the criterion standard for diagnosis. A practitioner (pediatric ED attending physician, emergency medicine or pediatric resident, pediatric ED fellow, or advanced practice provider) obtained a standardized history from the patient to assess for cervicitis or pelvic inflammatory disease according to the Centers for Disease Control and Prevention criteria. They then recorded the likelihood of cervicitis or pelvic inflammatory disease on a 100-mm visual analog scale. The same practitioner then performed a pelvic examination and again recorded the likelihood of cervicitis or pelvic inflammatory disease on a visual analog scale with this additional information. Using the results of the urine sexually transmitted infection tests, the practitioner calculated and compared the test characteristics of history alone and history with pelvic examination. RESULTS: Two hundred eighty-eight patients were enrolled, of whom 79 had positive urine test results for chlamydia, gonorrhea, or trichomonas, with a sexually transmitted infection rate of 27.4% (95% confidence interval [CI] 22.6% to 32.8%). The sensitivity of history alone in diagnosis of cervicitis or pelvic inflammatory disease was 54.4% (95% CI 42.8% to 65.5%), whereas the specificity was 59.8% (95% CI 52.8% to 66.4%). The sensitivity of history with pelvic examination in diagnosis of cervicitis or pelvic inflammatory disease was 48.1% (95% CI 36.8% to 59.5%), whereas the specificity was 60.7% (95% CI 53.8% to 67.3%). The information from the pelvic examination changed management in 71 cases; 35 of those cases correlated with the sexually transmitted infection test and 36 did not. CONCLUSION: For young female patients with suspected cervicitis or pelvic inflammatory disease, the pelvic examination does not increase the sensitivity or specificity of diagnosis of chlamydia, gonorrhea, or trichomonas compared with taking a history alone. Because the test characteristics for the pelvic examination are not adequate, its routine performance should be reconsidered.

Acquired Hypofibrinogenemia Before Asparaginase Exposure During Induction Therapy for Pediatric Acute Lymphoblastic Leukemia: A Report of 2 Cases and Review of the Literature.

Coagulopathy in pediatric leukemia patients is typically associated with acute promyelocytic leukemia or after asparaginase use in acute lymphoblastic leukemia. Rarely seen in acute lymphoblastic leukemia, we report 2 patients who presented with normal coagulation markers, but subsequently developed severe hypofibrinogenemia and bleeding in induction before administration of asparaginase. In both cases, cryoprecipitate was administered as initial treatment for bleeding associated with the hypofibrinogenemia. One patient was refractory to cryoprecipitate replacement and required treatment with human fibrinogen concentrate due to the persistence of hypofibrinogenemia with significant bleeding. The hypofibrinogenemia was transient in both cases and resolved within a few weeks.

Nonoperative Management of Blunt Splenic Trauma in Patients with Traumatic Brain Injury: Feasibility and Outcomes.

INTRODUCTION: Preventing secondary insult to the brain is imperative following traumatic brain injury (TBI). Although TBI does not preclude nonoperative management (NOM) of splenic injuries, development of hypotension in this setting may be detrimental and could therefore lead trauma surgeons to a lower threshold for operative intervention and a potentially higher risk of failure of NOM (FNOM). We hypothesized that the presence of a TBI in patients with blunt splenic injury would lead to a higher risk of FNOM. METHODS: Patients with blunt splenic injury were selected from the National Trauma Data Bank research datasets from 2007 to 2011. TBI was defined as AIS head ≥ 3 and FNOM as patients who underwent a spleen-related operation after 2 h from admission. TBI patients were compared to those without head injury. The primary outcome was FNOM. RESULTS: Of 47,713 patients identified, 41,436 (86.8%) underwent a trial of NOM. FNOM was identical (10.6 vs. 10.8%, p = 0.601) among patients with and without TBI. TBI patients had lower adjusted odds for FNOM (AOR 0.66, p < 0.001), even among those with a high-grade splenic injury (AOR 0.68, p < 0.001). No difference in adjusted mortality was noted when comparing TBI patients with and without FNOM (AOR 1.01, p = 0.95). CONCLUSIONS: NOM of blunt splenic trauma in TBI patients has higher adjusted odds for success. This could be related to interventions targeting prevention of secondary brain injury. Further studies are required to identify those specific practices that lead to a higher success rate of NOM of splenic trauma in TBI patients.

Using Pleth Variability as a Triage Tool for Children With Obstructive Airway Disease in a Pediatric Emergency Department.

OBJECTIVES: Patients with obstructive airway disease have varying degrees of pulsus paradoxus that correlate with illness severity. Pulsus paradoxus can be measured using plethysmography. We investigated whether plethysmograph (pleth) variability on admission to the pediatric emergency department (ED) could predict patient disposition. We hypothesized that patients with a larger pleth variability would have a higher likelihood of being admitted to a general pediatrics unit or the intensive care unit (ICU). METHODS: We conducted a prospective single-center study of children aged 1 to 18 years who presented to a pediatric ED with a diagnosis of asthma or reactive airway disease. The pleth variability index (PVI) was calculated from their initial plethysmography tracing. Disposition from the ED was recorded as discharge, admission to the floor, or admission to the ICU. RESULTS: A total of 117 patients were included in our study. Forty-eight patients were discharged home, 61 were admitted to the floor, and 8 were admitted to the ICU. The median PVI for each of these groups was 0.27 (interquartile range [IQR], 0.19-0.39) for discharges, 0.29 (IQR, 0.20-0.44) for patients admitted to the floor, and 0.56 (IQR, 0.35-0.70) for patients admitted to the ICU. A Kruskal-Wallis test demonstrated a significant difference in the PVI between each of the groups (P = 0.0087). CONCLUSIONS: Our results suggest that PVI may be a useful tool in the triage of children who present to the ED with obstructive airway disease. Further studies should aim to assess the validity of PVI in predicting the response to bronchodilator therapy during the course of a patient's hospitalization.

AI Alone Will Not Reduce the Administrative Burden of Health Care.

This Viewpoint considers AI's limits in solving the medical billing quagmire and argues that standardizing health insurance claim forms and simplifying billing must occur before AI can shoulder the load.

Shifting Away From Fee-For-Service: Alternative Approaches to Payment in Gastroenterology.

Fee-for-service payments encourage high-volume services rather than high-quality care. Alternative payment models (APMs) aim to realign financing to support high-value services. The 2 main components of gastroenterologic care, procedures and chronic care management, call for a range of APMs. The first step for gastroenterologists is to identify the most important conditions and opportunities to improve care and reduce waste that do not require financial support. We describe examples of delivery reforms and emerging APMs to accomplish these care improvements. A bundled payment for an episode of care, in which a provider is given a lump sum payment to cover the cost of services provided during the defined episode, can support better care for a discrete procedure such as a colonoscopy. Improved management of chronic conditions can be supported through a per-member, per-month (PMPM) payment to offer extended services and care coordination. For complex chronic conditions such as inflammatory bowel disease, in which the gastroenterologist is the principal care coordinator, the PMPM payment could be given to a gastroenterology medical home. For conditions in which the gastroenterologist acts primarily as a consultant for primary care, such as noncomplex gastroesophageal reflux or hepatitis C, a PMPM payment can support effective care coordination in a medical neighborhood delivery model. Each APM can be supplemented with a shared savings component. Gastroenterologists must engage with and be early leaders of these redesign discussions to be prepared for a time when APMs may be more prevalent and no longer voluntary.

Tissue Plasminogen Activator Use in Children: Bleeding Complications and Thrombus Resolution.

OBJECTIVE: To review our institutional experience with tissue plasminogen activator (tPA) to determine outcomes related to bleeding complications and thrombus resolution. STUDY DESIGN: We performed a retrospective review of all patients who received systemic tPA for thrombolysis. Data points included location of thrombus, initial and maximum tPA dose, and duration of tPA. The primary endpoint was bleeding complication. RESULTS: Between 2005 and 2014, 46 patients received systemic tPA for thrombolysis: 17 (37%) were patients with a primary cardiac diagnosis, there were 17 (37%) hematology/oncology patients, and 12 (26%) patients with noncardiac, nonhematology/oncology diagnoses. The indication for tPA was central venous thrombus (n = 23), pulmonary artery thrombus (n = 9), and cardiac or aortic thrombus (n = 14). Bleeding complications occurred in 15 patients (33%). Median initial tPA dose in the bleeding complication group was 0.10 mg/kg/h vs 0.03 mg/kg/h in the group without bleeding complication group (P = .01). Cardiac patients experienced more bleeding complications (P = .01). Multivariate analysis indicated that dose of tPA (P = .01) and diagnostic category (P < .01) were associated with bleeding complication. Complete thrombus resolution occurred in 21 patients, partial in 10 patients, and no resolution in 15 patients. Complete resolution of thrombus was not associated with diagnosis, thrombus location, tPA dose, or duration. CONCLUSIONS: Cardiac patients appear to be at highest risk of bleeding complication; bleeding complications were associated with higher doses of tPA, and cardiac patients were the cohort who received the highest doses of tPA. Higher tPA doses are associated with increased risk of bleeding complication but are not associated with successful thrombus resolution.

Variation in Specialty Outpatient Care Patterns in the Medicare Population.

BACKGROUND: Multiple payment reform efforts are under way to improve the value of care delivered to Medicare beneficiaries, yet few directly address the interface between primary and specialty care. OBJECTIVE: To describe regional variation in outpatient visits for individual specialties and the association between specialty physician-specific payments and patient-reported satisfaction with care and health status. DESIGN: Retrospective cross-sectional study. PATIENTS: A 20 % random sample of Medicare fee-for-service beneficiaries in 2012. MAIN MEASURES: Regions were grouped into quartiles of specialist index, defined as the observed/expected regional likelihood of having an outpatient visit to a specialist, for ten common specialties, adjusting for age, sex, and race. Outcomes were per capita specialty-specific physician payments and Medicare Current Beneficiary Survey responses. KEY RESULTS: The proportion of beneficiaries seeing a specialist varied the most for endocrinology and gastroenterology (3.7- and 3.9-fold difference between the highest and lowest quartiles, respectively) and least for orthopedics and urology (1.5- and 1.7-fold difference, respectively). Multiple analyses suggested that this variation was not explained by prevalence of disease. Average specialty-specific payments were strongly associated with the likelihood of visiting a specialist. Differences in per capita payments from lowest (Q1) to highest quartiles (Q4) were greatest for cardiology ($89, $135, $172, $251) and dermatology ($46, $64, $82, $124). Satisfaction with overall care (median [interquartile range] across specialties: Q1, 93.3 % [92.6-93.7 %]; Q4, 93.1 % [92.9-93.2 %]) and self-reported health status (Q1, 37.1 % [36.9-37.7 %]; Q4, 38.2 % [37.2-38.4 %]) was similar across quartiles. Satisfaction with access to specialty care was consistently lower in the lowest quartile of specialty index (Q1, 89.7 % [89.2-91.1 %]; Q4, 94.5 % [94.4-94.8 %]). CONCLUSIONS: Substantial regional variability in outpatient specialist visits is associated with greater payments with limited benefits in terms of patient-reported satisfaction with care or reported health status. Reducing outpatient physician visits may represent an important opportunity to improve the efficiency of care.
