A Randomized Trial of Enteral Glutamine for Treatment of Burn Injuries.

BACKGROUND: Glutamine is thought to have beneficial effects on the metabolic and stress response to severe injury. Clinical trials involving patients with burns and other critically ill patients have shown conflicting results regarding the benefits and risks of glutamine supplementation. METHODS: In a double-blind, randomized, placebo-controlled trial, we assigned patients with deep second- or third-degree burns (affecting ≥10% to ≥20% of total body-surface area, depending on age) within 72 hours after hospital admission to receive 0.5 g per kilogram of body weight per day of enterally delivered glutamine or placebo. Trial agents were given every 4 hours through a feeding tube or three or four times a day by mouth until 7 days after the last skin grafting procedure, discharge from the acute care unit, or 3 months after admission, whichever came first. The primary outcome was the time to discharge alive from the hospital, with data censored at 90 days. We calculated subdistribution hazard ratios for discharge alive, which took into account death as a competing risk. RESULTS: A total of 1209 patients with severe burns (mean burn size, 33% of total body-surface area) underwent randomization, and 1200 were included in the analysis (596 patients in the glutamine group and 604 in the placebo group). The median time to discharge alive from the hospital was 40 days (interquartile range, 24 to 87) in the glutamine group and 38 days (interquartile range, 22 to 75) in the placebo group (subdistribution hazard ratio for discharge alive, 0.91; 95% confidence interval [CI], 0.80 to 1.04; P = 0.17). Mortality at 6 months was 17.2% in the glutamine group and 16.2% in the placebo group (hazard ratio for death, 1.06; 95% CI, 0.80 to 1.41). No substantial between-group differences in serious adverse events were observed. CONCLUSIONS: In patients with severe burns, supplemental glutamine did not reduce the time to discharge alive from the hospital.

Implementation of Extracorporeal CPR Programs for Out-of-Hospital Cardiac Arrest: Another Tale of Two County Hospitals.

Extracorporeal cardiopulmonary resuscitation (ECPR) is a form of intensive life support that has seen increasing use globally to improve outcomes for patients who experience out-of-hospital cardiac arrest (OHCA). Hospitals with advanced critical care capabilities may be interested in launching an ECPR program to offer this support to the patients they serve; however, to do so, they must first consider the significant investment of resources necessary to start and sustain the program. The existing literature describes many single-center ECPR programs and often focuses on inpatient care and patient outcomes in hospitals with cardiac surgery capabilities. However, building a successful ECPR program and using this technology to support an individual patient experiencing refractory cardiac arrest secondary to a shockable rhythm depends on efficient out-of-hospital and emergency department (ED) management. This article describes the process of implementing 2 intensivist-led ECPR programs with limited cardiac surgery capability. We focus on emergency medical services and ED clinician roles in identifying patients, mobilizing resources, initiation and management of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in the ED, and ongoing efforts to improve ECPR program quality. Each center experienced a significant learning curve to reach goals of arrest-to-flow times of cannulation for ECPR. Building consensus from multidisciplinary stakeholders, including out-of-hospital stakeholders; establishing shared expectations of ECPR outcomes; and ensuring adequate resource support for ECPR activation were all key lessons in improving our ECPR programs.

OCT-Based Angiography and Surface Topography in Burn-Damaged Skin.

BACKGROUND AND OBJECTIVES: There is a clinical need for an accurate, non-invasive imaging tool that can provide the objective assessment of burn wounds. The aims of this study are to demonstrate the potential of optical coherence tomography (OCT) in evaluating burn wound healing, as well as exploring the physiological basis of human wound healing. STUDY DESIGN/MATERIALS AND METHODS: This was a retrospective study. Seven patients with severe burn wounds who were admitted to Harborview Medical Center were imaged using an in-house-built, clinical-prototype OCT system. OCT imaging was carried out at multiple scan sites on the burned skin across two time points (imaging session #1 and #2) with a field of view of ~9 × 9 mm. Due to pathological differences among burn zones, scan sites were classified into red sites (zone of hyperemia), white sites (zone of coagulation), and mixed sites. In addition to obtaining qualitative en face vascular and surface topography maps, we quantified vascular area density and surface roughness for comparative purposes. RESULTS: En face vascular and surface topography maps demonstrated numerous morphological changes over both imaging sessions associated with burn injury, such as altered blood flow and loss of regular texture. Quantitative analyses revealed that during imaging session #1, vascular area density was significantly increased within the red sites compared with that of a healthy control (P = 0.0130), while vascular area density was significantly decreased within the white sites compared with that of a healthy control (P < 0.0001). During imaging session #2, vascular area density was significantly reduced to a more normal range within the red sites compared with imaging session #1 (P = 0.0215); however, vascular area density was still significantly lower within the white sites compared with that of a healthy control (P < 0.0001). Furthermore, vascular area density and surface roughness were significantly increased within the white sites during imaging session #2 compared with imaging session #1 (both P < 0.0001). CONCLUSIONS: OCT is clinically feasible to monitor vascular changes and alterations in skin surface roughness during the process of burn wound healing. Variations in vascular area density and roughness measurements within the burn wounds revealed by OCT offer some key insights into the underlying pathophysiological mechanisms responsible for wound healing, which may become critical biological indicators in future clinical evaluation and monitoring of wound healing.

Application of OCT-Derived Attenuation Coefficient in Acute Burn-Damaged Skin.

BACKGROUND AND OBJECTIVES: There remains a need to objectively monitor burn wound healing within a clinical setting, and optical coherence tomography (OCT) is proving itself one of the ideal modalities for just such a use. The aim of this study is to utilize the noninvasive and multipurpose capabilities of OCT, along with its cellular-level resolution, to demonstrate the application of optical attenuation coefficient (OAC), as derived from OCT data, to facilitate the automatic digital segmentation of the epidermis from scan images and to work as an objective indicator for burn wound healing assessment. STUDY DESIGN/MATERIALS AND METHODS: A simple, yet efficient, method was used to estimate OAC from OCT images taken over multiple time points following acute burn injury. This method enhanced dermal-epidermal junction (DEJ) contrast, which facilitated the automatic segmentation of the epidermis for subsequent thickness measurements. In addition, we also measured and compared the average OAC of the dermis within said burns for correlative purposes. RESULTS: Compared with unaltered OCT maps, enhanced DEJ contrast was shown in OAC maps, both from single A-lines and completed B-frames. En face epidermal thickness and dermal OAC maps both demonstrated significant changes between imaging sessions following burn injury, such as a loss of epidermal texture and decreased OAC. Quantitative analysis also showed that OAC of acute burned skin decreased below that of healthy skin following injury. CONCLUSIONS: Our study has demonstrated that the OAC estimated from OCT data can be used to enhance imaging contrast to facilitate the automatic segmentation of the epidermal layer, as well as help elucidate our understanding of the pathological changes that occur in human skin when exposed to acute burn injury, which could serve as an objective indicator of skin injury and healing.

Factors Affecting Employment After Burn Injury in the United States: A Burn Model System National Database Investigation.

OBJECTIVE: To investigate the effect of patient and injury characteristics on employment for working-age, adult survivors of burn injury using the multicenter Burn Model System national database. DESIGN: Longitudinal survey. SETTING: Multicenter regional burn centers. PARTICIPANTS: Adult burn survivors (N=967) age≥18 years with known employment status prior to injury were included in the analysis at 12 months after injury. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Employment status at 12 months after injury. RESULTS: The analyses determined that those employed preinjury had higher odds of being employed (odds ratio [OR]=8.1; 95% confidence interval [CI], 4.9-13.1). White, non-Hispanic individuals were also more likely to be employed (OR=1.49; 95% CI, 1.0-2.1). Older individuals, females, those with longer hospitalizations, amputation during the acute hospitalization, and those with high pain interference at hospital discharge had lower odds of working after injury. Preinjury living situation, preinjury alcohol and drug misuse, number of acute operations and burn size (total body surface area, %) were not significant predictors of employment status at 12 months after burn injury. CONCLUSION: Preinjury employment remains the most significant predictor for postburn employment. Although past reports have focused on predictors for postburn employment, we believe that we need to seek greater understanding of modifiable risk factors for unemployment and examine issues related to work retention, performance, accommodations, and career trajectories for the working-age survivor of burn injury.

Readiness of US General Surgery Residents for Independent Practice.

OBJECTIVE: This study evaluates the current state of the General Surgery (GS) residency training model by investigating resident operative performance and autonomy. BACKGROUND: The American Board of Surgery has designated 132 procedures as being "Core" to the practice of GS. GS residents are expected to be able to safely and independently perform those procedures by the time they graduate. There is growing concern that not all residents achieve that standard. Lack of operative autonomy may play a role. METHODS: Attendings in 14 General Surgery programs were trained to use a) the 5-level System for Improving and Measuring Procedural Learning (SIMPL) Performance scale to assess resident readiness for independent practice and b) the 4-level Zwisch scale to assess the level of guidance (ie, autonomy) they provided to residents during specific procedures. Ratings were collected immediately after cases that involved a categorical GS resident. Data were analyzed using descriptive statistics and supplemented with Bayesian ordinal model-based estimation. RESULTS: A total of 444 attending surgeons rated 536 categorical residents after 10,130 procedures. Performance: from the first to the last year of training, the proportion of Performance ratings for Core procedures (n = 6931) at "Practice Ready" or above increased from 12.3% to 77.1%. The predicted probability that a typical trainee would be rated as Competent after performing an average Core procedure on an average complexity patient during the last week of residency training is 90.5% (95% CI: 85.7%-94%). This falls to 84.6% for more complex patients and to less than 80% for more difficult Core procedures. Autonomy: for all procedures, the proportion of Zwisch ratings indicating meaningful autonomy ("Passive Help" or "Supervision Only") increased from 15.1% to 65.7% from the first to the last year of training. For the Core procedures performed by residents in their final 6 months of training (cholecystectomy, inguinal/femoral hernia repair, appendectomy, ventral hernia repair, and partial colectomy), the proportion of Zwisch ratings (n = 357) indicating near-independence ("Supervision Only") was 33.3%. CONCLUSIONS: US General Surgery residents are not universally ready to independently perform Core procedures by the time they complete residency training. Progressive resident autonomy is also limited. It is unknown if the amount of autonomy residents do achieve is sufficient to ensure readiness for the entire spectrum of independent practice.

Chronic Use of Prescription Pain Medication and Outcomes in Patients with Burn Injury: A Burn Model System National Database Study.

OBJECTIVE: This study attempts to examine long-term pain medication usage after burn injury and its association with functional and psychosocial outcomes. DESIGN: This is a multi-center retrospective cohort study utilizing the Burn Model System National Longitudinal Database. Participants injured from 2015 to 2021 were divided into two groups, those taking and not taking prescription pain medication at 12 months after injury. Regression analyses examined associations between pain medication use and outcomes at 12 months, adjusting for demographics, burn size, length of hospital stay, and pre-injury pain medication use and employment status. Outcomes included VR-12 Physical and Mental Component Summary scores (PCS and MCS), Patient-Reported Outcomes Measurement Information System (PROMIS-29) Anxiety and Depression scores, Satisfaction with Life Scale (SWLS), and employment status. RESULTS: Of 358 participants analyzed, prescription pain medication use was associated with worse outcomes at 12 months: PCS (ß = -7.11, p < 0.001), MCS (ß = -6.01, p < 0.001), and PROMIS-29 Depression (ß = 4.88, p < 0.001) and Anxiety (ß = 6.16, p < 0.001). SWLS was not significantly associated with pain medication use (p = 0.069) and those taking pain medication were 52% less likely to be employed at 12 months (p = 0.035). CONCLUSION: There is a significant association between prescription pain medication use and worse physical, mental, and employment outcomes at 12 months after burn injury.

Examining the association between military service history and outcomes after burn injury.

INTRODUCTION: The association between military service history and long-term outcomes after burn injury is unknown. This study uses data from the Burn Model System National Database to compare outcomes of individuals with and without self-reported military service history. METHODS: Outcome measures were assessed at 12 months after injury including the Veterans Rand-12 Item Health Survey/Short Form-12, Satisfaction With Life Scale, Patient Reported Outcomes Measure Information System 29, 4-D Itch scale, Post Traumatic Stress Disorder Check List - Civilian Version, self-reported Post Traumatic Stress Disorder, and employment status. This study included 675 people with burns of whom 108 reported a history of military service. RESULTS: The military service history group was more likely to be older, and male. Those with military service were most likely to be on Medicare insurance and those without military service history were most likely to be on Private Insurance/HMP/PPO. No significant differences were found between those with and without military service history in the outcome measures. CONCLUSIONS: Further research should examine differences in outcomes between civilians and those with military service history, including elements of resilience and post traumatic growth.

Fever and infections in surgical intensive care: an American Association for the Surgery of Trauma Critical Care Committee clinical consensus document.

The evaluation and workup of fever and the use of antibiotics to treat infections is part of daily practice in the surgical intensive care unit (ICU). Fever can be infectious or non-infectious; it is important to distinguish between the two entities wherever possible. The evidence is growing for shortening the duration of antibiotic treatment of common infections. The purpose of this clinical consensus document, created by the American Association for the Surgery of Trauma Critical Care Committee, is to synthesize the available evidence, and to provide practical recommendations. We discuss the evaluation of fever, the indications to obtain cultures including urine, blood, and respiratory specimens for diagnosis of infections, the use of procalcitonin, and the decision to initiate empiric antibiotics. We then describe the treatment of common infections, specifically ventilator-associated pneumonia, catheter-associated urinary infection, catheter-related bloodstream infection, bacteremia, surgical site infection, intra-abdominal infection, ventriculitis, and necrotizing soft tissue infection.

TQIP mortality reporting system case reports: Unanticipated mortality due to communication and handoff failures.

ABSTRACT: The TQIP Mortality Reporting System is an online anonymous case reporting system designed to share experiences from rare events that may have contributed to unanticipated mortality at contributing trauma centers. The TQIP Mortality Reporting System Working group monitors submitted cases and organizes them into emblematic themes. This report summarizes unanticipated mortality from two cases of failure of communication and handoff, and presents strategies to mitigate these events locally with the hope of decreasing unanticipated mortality nationwide.

Assessment and Management of Acute Burn Injuries.

Burn injuries can affect patients from all walks of life and represent a significant healthcare problem globally. The skin is the largest organ of the body and consequences of injury range of minor pain to severe end-organ dysfunction and even death. The acute assessment and management of burn-injured patients is a critical part of their short-term and long-term outcomes and often benefit from specialty, multidisciplinary care. Local wound care and appropriate excision and grafting are important parts of managing the functional, cosmetic, and physiologic derangements caused by burn injuries. Large burns also require judicious fluid resuscitation. Electrical, chemical, and inhalational injuries are less common than thermal burns but require additional care and are often associated with increased morbidity.

Fungal brain abscess in a severely burned patient.

Burn patients are particularly susceptible to atypical and opportunistic infections. Here we report an unusual case of a 40-year-old previously healthy man with a 74% TBSA burn injury who developed a presumed Fusarium brain abscess. This patient had a complicated infectious course including ESBL E. coli and Elizabethkingia bacteremia and pneumonia, MRSA ventilator-associated pneumonia, Mycobacterium abscessus bacteremia, and Fusarium fungemia. After diagnosis with a fungal abscess on magnetic resonance imaging of the brain, the patient was treated with aspiration and appropriate antifungal therapies. The patient was eventually transitioned to comfort care and died on hospital day 167. This is the first published report of a Fusarium-related brain abscess since it was first reported in a case report of a burned child in 1974.

The risks of sedation and pain control during burn resuscitation: Increased opioids lead to over-resuscitation and hypotension.

INTRODUCTION: Pain management and sedation are necessary in severely burned persons. Balancing pain control, obtundation, and hemodynamic suppression can be challenging. We hypothesized that increased sedation during burn resuscitation is associated with increased intravenous fluid administration and hemodynamic instability. METHODS: A retrospective review of a single burn center was performed from 2014 to 2019 for all admissions to the burn unit with > 20% total body surface area (TBSA) burns. Within 48 h of admission, we compared total amounts of sedation/pain medications (morphine milligram equivalents (MME), propofol, dexmedetomidine, benzodiazepines) with total resuscitation volumes and frequency of hypotensive episodes. Resuscitation volumes and frequency of hypotension were modeled with multivariable linear regression adjusting for burn severity and weight. RESULTS: 208 patients were included with median age of 43 years (IQR 29-55) and median %TBSA of 31 (IQR 25-44). Median 48-hour resuscitation milliliters per weight per %TBSA were 3.3 (IQR 2.28-4.92). Pain/sedative medications included a combination of opioids in 99%, benzodiazepines in 73%, propofol in 31%, and dexmedetomidine in 11% of patients. MMEs were associated with greater resuscitation volumes (95% CI: 0.15-0.54, p = 0.01) as well as number of hypotensive events (95% CI: 1.57-2.7, p < 0.001). No associations were noted with other sedative medications when comparing the number of hypotensive events and resuscitation volumes. CONCLUSIONS: Increased opioid administration has physiological consequences and should be carefully monitored during resuscitation as higher volume administrations lead to worse outcomes. Opioids and sedating medications should be titrated to the least amount needed to achieve reasonable comfort and sedation.

American Burn Association Strategic Quality Summit 2022: Setting the Direction for the Future.

The American Burn Association (ABA) hosted a Burn Care Strategic Quality Summit (SQS) in an ongoing effort to advance the quality of burn care. The goals of the SQS were to discuss and describe characteristics of quality burn care, identify goals for advancing burn care, and develop a roadmap to guide future endeavors while integrating current ABA quality programs. Forty multidisciplinary members attended the two-day event. Prior to the event, they participated in a pre-meeting webinar, reviewed relevant literature, and contemplated statements regarding their vision for improving burn care. At the in-person, professionally facilitated Summit in Chicago, Illinois, in June 2022, participants discussed various elements of quality burn care and shared ideas on future initiatives to advance burn care through small and large group interactive activities. Key outcomes of the SQS included burn-related definitions of quality care, avenues for integration of current ABA quality programs, goals for advancing quality efforts in burn care, and work streams with tasks for a roadmap to guide future burn care quality-related endeavors. Work streams included roadmap development, data strategy, quality program integration, and partners and stakeholders. This paper summarizes the goals and outcomes of the SQS and describes the status of established ABA quality programs as a launching point for futurework.

Veno-venous Extracorporeal Membrane Oxygenation for COVID-19: A Call For System-Wide Checks to Ensure Equitable Delivery For All.

Extracorporeal membrane oxygenation (ECMO) has emerged in the COVID-19 pandemic as a potentially beneficial yet scare resource for treating critically ill patients, with variable allocation across the United States. The existing literature has not addressed barriers patients may face in access to ECMO as a result of healthcare inequity. We present a novel patient-centered framework of ECMO access, providing evidence for potential bias and opportunities to mitigate this bias at every stage between a marginalized patient's initial presentation to treatment with ECMO. While equitable access to ECMO support is a global challenge, this piece focuses primarily on patients in the United States with severe COVID-19-associated ARDS to draw from current literature on VV-ECMO for ARDS and does not address issues that affect ECMO access on a more international scale.

Implementation of Extracorporeal Membrane Oxygenation Without On-Site Cardiac Surgery or Perfusion Support: A Tale of Two County Hospitals.

Patients with refractory respiratory and cardiac failure may present to noncardiac surgery centers. Prior studies have demonstrated that acute care surgeons, intensivists, and emergency medicine physicians can safely cannulate and manage patients receiving extracorporeal membrane oxygenation (ECMO). Harborview Medical Center (Harborview) and Hennepin County Medical Center (Hennepin) are both urban, county-owned, level 1 trauma centers that implemented ECMO without direct, on-site cardiac surgery or perfusion support. Both centers 1) use an ECMO specialist model staffed by specially trained nurses and respiratory therapists and 2) developed comparable training curricula for ECMO specialists, intensivists, surgeons, and trainees. Each program began with venovenous ECMO to provide support for refractory hypoxemic respiratory failure and subsequently expanded to venoarterial ECMO support. The coronavirus disease 2019 (COVID-19) pandemic created an impetus for restructuring, with each program creating a consulting service to facilitate ECMO delivery across multiple intensive care units (ICUs) and to promote fellow and resident training and experience. Both Harborview and Hennepin, urban county hospitals 1,700 miles apart in the United States, independently implemented and operate adult ECMO programs without involvement from cardiovascular surgery or perfusion services. This experience further supports the role of ECMO specialists in the delivery of extracorporeal life support.

Setting the Standard: Using the ABA Burn Registry to Benchmark Risk Adjusted Mortality.

Reports of single center experience and studies of larger databases have identified several predictors of burn center mortality, including age, burn size, and inhalation injury. None of these analyses has been broad enough to allow benchmarking across burn centers. The purpose of this study was to derive a reliable, risk-adjusted, statistical model of mortality based on real-life experience at many burn centers in the U.S. We used the American Burn Association 2020 Full Burn Research Dataset, from the Burn Center Quality Platform (BCQP) to identify 130,729 subjects from July 2015 through June 2020 across 103 unique burn centers. We selected 22 predictor variables, from over 50 recorded in the dataset, based on completeness (at least 75% complete required) and clinical significance. We used gradient-boosted regression, a form of machine learning, to predict mortality and compared this to traditional logistic regression. Model performance was evaluated with AUC and PR curves. The CatBoost model achieved a test AUC of 0.980 with an average precision of 0.800. The logistic regression produced an AUC of 0.951 with an average precision of 0.664. While AUC, the measure most reported in the literature, is high for both models, the CatBoost model is markedly more sensitive, leading to a substantial improvement in precision. Using BCQP data, we can predict burn mortality allowing comparison across burn centers participating in BCQP.

Using a National Burn Registry to Develop a Model for Risk-Adjusted Length of Stay Benchmarking.

Length of stay (LOS) is a frequently reported outcome after a burn injury. LOS benchmarking will benefit individual burn centers as a way to measure their performance and set expectations for patients. We sought to create a nationwide, risk-adjusted model to allow for LOS benchmarking based on the data from a national burn registry. Using data from the American Burn Association's Burn Care Quality Platform, we queried admissions from 7/2015 to 6/2020 and identified 130,729 records reported by 103 centers. Using 22 predictor variables, comparisons of unpenalized linear regression and Gradient boosted (CatBoost) regressor models were performed by measuring the R2 and concordance correlation coefficient on the application of the model to the test dataset. The CatBoost model applied to the bootstrapped versions of the entire dataset was used to calculate O/E ratios for individual burn centers. Analyses were run on 3 cohorts: all patients, 10-20% TBSA, >20% TBSA. The CatBoost model outperformed the linear regression model with a test R2 of 0.67 and CCC of 0.81 compared with the linear model with R2=0.50, CCC=0.68. The CatBoost was also less biased for higher and lower LOS durations. Gradient-boosted regression models provided greater model performance than traditional regression analysis. Using national burn data, we can predict LOS across contributing burn centers while accounting for patient and center characteristics, producing more meaningful O/E ratios. These models provide a risk-adjusted LOS benchmarking using a robust data source, the first of its kind, for burn centers.

Error reduction in trauma care: Lessons from an anonymized, national, multicenter mortality reporting system.

BACKGROUND: Twenty years ago, the landmark report To Err Is Human illustrated the importance of system-level solutions, in contrast to person-level interventions, to assure patient safety. Nevertheless, rates of preventable deaths, particularly in trauma care, have not materially changed. The American College of Surgeons Trauma Quality Improvement Program developed a voluntary Mortality Reporting System to better understand the underlying causes of preventable trauma deaths and the strategies used by centers to prevent future deaths. The objective of this work is to describe the factors contributing to potentially preventable deaths after injury and to evaluate the effectiveness of strategies identified by trauma centers to mitigate future harm, as reported in the Mortality Reporting System. METHODS: An anonymous structured web-based reporting template based on the Joint Commission on Accreditation of Healthcare Organizations taxonomy was made available to trauma centers participating in the Trauma Quality Improvement Program to allow for reporting of deaths that were potentially preventable. Contributing factors leading to death were evaluated. The effectiveness of mitigating strategies was assessed using a validated framework and mapped to tiers of effectiveness ranging from person-focused to system-oriented interventions. RESULTS: Over a 2-year period, 395 deaths were reviewed. Of the mortalities, 33.7% were unanticipated. Errors pertained to management (50.9%), clinical performance (54.7%), and communication (56.2%). Human failures were cited in 61% of cases. Person-focused strategies like education were common (56.0%), while more effective system-based strategies were seldom used. In 7.3% of cases, centers could not identify a specific strategy to prevent future harm. CONCLUSION: Most strategies to reduce errors in trauma centers focus on changing the performance of providers rather than system-level interventions such as automation, standardization, and fail-safe approaches. Centers require additional support to develop more effective mitigations that will prevent recurrent errors and patient harm. LEVEL OF EVIDENCE: Therapeutic/Care Management, level V.
