Abstract
OBJECTIVE To compare median Sophia Observation withdrawal Symptoms scale (SOS) scores between -intravenous methadone dosing scheduled every 6 hours or every 8 hours for iatrogenic withdrawal -syndrome (IWS). METHODS This single-center, retrospective chart review evaluated patients aged 4 weeks through 18 years treated with intravenous methadone for IWS. Children admitted to the pediatric intensive care unit (PICU) of a tertiary care children's hospital between August 2017 and July 2021 and treated for IWS for at least 48 hours were eligible for inclusion. Methadone dosing schedules were compared, with a primary outcome of median Sophia Observation withdrawal Symptoms (SOS) score during the first 24 hours after cessation of continuous fentanyl infusion. Secondary outcomes included PICU and general pediatric unit lengths of stay, extubation failure rates, and mortality. RESULTS Twenty patients met inclusion criteria, with 9 in the 6-hour dosing group. There was no difference in median SOS score, extubation failure, length of stay, or mortality between the 2 groups. CONCLUSIONS During the first 24 hours after cessation of continuous fentanyl, there appears to be no -difference in IWS severity, as determined by bedside nurse scoring, between patients treated with -intravenous methadone every 6 hours compared with every 8 hours.

Abstract
OBJECTIVES To comprehensively classify interventions performed by pediatric critical care clinical pharmacists and quantify cost avoidance (CA) generated through their accepted interventions. DESIGN A multicenter, prospective, observational study performed between August 2018 and January 2019. SETTING Academic and community hospitals in the United States with pediatric critical care units. SUBJECTS Pediatric clinical pharmacists. INTERVENTIONS Pharmacist recommendations were classified into one of 38 total intervention categories associated with CA. MEASUREMENTS AND MAIN RESULTS Nineteen pediatric pharmacists at five centers documented 1,458 accepted interventions during 112 shifts on 861 critically ill pediatric patients. This calculated to an associated CA of $450,590. The accepted interventions and associated CA in the six established categories included as follows: adverse drug event prevention (155 interventions, $118,901 CA), resource utilization (267 interventions; $59,020), individualization of patient care (898 interventions, $217,949 CA), prophylaxis (8 interventions, $453 CA), hands-on care (30 interventions, $35,509 CA), and administrative/supportive tasks (108 interventions, $18,758 CA). The average associated CA was $309 per accepted intervention, $523 per patient day, and $4,023.13 per pediatric clinical pharmacist shift. The calculated potential annualized CA of accepted interventions from a pediatric pharmacist was $965,550, resulting in a potential monetary-associated CA-to-pharmacist salary ratio between $1.5:1 and $5.2:1. CONCLUSIONS There is potential for significant avoidance of healthcare costs when pediatric pharmacists are involved in the care of critically and emergently ill pediatric patients, with a monetary potential CA-to-pediatric pharmacist salary ratio to be between $1.5:1 and $5.2:1.

Abstract
OBJECTIVES Sedation and pain medications are necessary in the management of postoperative pediatric cardiac patients. Prolonged exposure to these medications can lead to negative side effects including withdrawal. We hypothesized that standardized weaning guidelines would decrease exposure to sedation medications and decrease withdrawal symptoms. The primary aim was to decrease average days of methadone exposure to within goal for moderate- and high-risk patients within 6 months. DESIGN Quality improvement methods were used to standardize sedation medication weaning in a pediatric cardiac ICU. SETTING This study took place at Duke Children's Hospital Pediatric Cardiac ICU in Durham, North Carolina from January 1, 2020, to December 31, 2021. PATIENTS Children less than 12 months old admitted to the pediatric cardiac ICU who underwent cardiac surgery. INTERVENTIONS Sedation weaning guidelines were implemented over the course of 12 months. Data were tracked every 6 months and compared with the 12 months pre-intervention. Patients were stratified into low, moderate, and high risk withdrawal categories based on duration of opioid infusion exposure. MEASUREMENTS AND MAIN RESULTS Total sample size was 94 patients in the moderate and high risk categories. Process measures included documentation of Withdrawal Assessment Tool scores and appropriate methadone prescription in patients which increased to 100% post-intervention. For outcome measures, we observed decreased dexmedetomidine infusion duration, decreased methadone wean duration, decreased frequency of elevated Withdrawal Assessment Tool scores, and decreased hospital length of stay post-intervention. For the primary aim, methadone wean duration consistently decreased after each study period. Our intervention did not adversely impact balancing measures. CONCLUSIONS A quality improvement initiative to standardize sedation weaning in a Pediatric Cardiac ICU was successfully implemented and was correlated with decreased duration of sedation medications, decreased withdrawal scores, and decreased length of stay.

Abstract
BACKGROUND Iatrogenic withdrawal syndrome (IWS) is a complication of prolonged sedation/analgesia in pediatric intensive care unit (PICU) patients. The epidemiology of IWS is poorly understood, as validated diagnostic tools are rarely used. The main objective of our study was to use the WAT-1 score to assess the incidence of IWS in our unit. The secondary objectives were to evaluate the consequences of IWS, associated factors, and management modalities. MATERIAL AND METHODS From July 2018 to January 2019, 48 children receiving endotracheal ventilation and sedation/analgesia by continuous infusion (>48 h) of benzodiazepines and/or opioids were included. As soon as sedation/analgesia was decreased and until 72 h after its complete discontinuation, the WAT-1 score was determined every 12 h. Substitution therapy was used for 98% of patients upon opioid and/or benzodiazepine withdrawal. IWS was defined as a WAT-1 score ≥3. Factors associated with IWS were assessed by univariate analysis. RESULTS IWS occurred in 25 (52%) patients. IWS was associated with a higher number of ventilator-associated pneumonia episodes (17 [68%] vs. one [4%]) and a longer PICU stay (13 [7; 25] vs. 9.0 [5.0; 10.5]) (p<0.001). Overall, 11 patients developed IWS after less than 5 days of sedation/analgesia. Severe head injury was associated with IWS (p = 0.03). Neither sedation discontinuation nor IWS prevention was standardized. CONCLUSION The high incidence and adverse consequences of IWS require improved prevention. Risk groups should be defined and a standardized withdrawal protocol established. The occurrence of IWS should be monitored routinely using a validated score.

Abstract
OBJECTIVES Evaluate the implementation of a pharmacist-managed opioid weaning regimen and objective opioid withdrawal assessment tool in pediatric patients requiring an opioid wean. We hypothesized that this combination would be associated with a reduction in the wean duration and length of stay and decrease episodes of opioid withdrawal. METHODS Retrospective cohort study utilizing pediatric inpatients requiring an inpatient opioid medication wean. The study was conducted in 3 phases from chart review of patients admitted from 2012 to 2020: baseline preintervention (phase 1), pharmacist-managed weaning regimen (phase 2), and addition of an objective assessment tool, the Withdrawal Assessment Tool-1 (phase 3). Data collection included the total wean duration, total duration of hospital admission, and number of episodes of opioid withdrawal. RESULTS The study included 115 patients with 36 patients in phases 1 and 3 and 43 patients in phase 2. Median age ranged from 0.46 to 0.84 years and the majority of children were males. No significant differences in patient characteristics such as age, weight, sex, and previous opioid exposure were found between phases. Length of stay, wean duration, and episodes of withdrawal with need for rescue dose all decreased significantly from phase 1 to phase 3. CONCLUSIONS Use of a pharmacist-managed weaning regimen combined with the Withdrawal Assessment Tool-1 tool was associated with significantly shorter methadone weans and overall length of stay. This has implications for wide spread dissemination and standardization of this approach in tertiary care children's hospitals caring for patients after ICU admission.

Abstract
Opioids are potent analgesics used to manage pain in both young and old, but the increased use in the pregnant population has significant individual and societal implications. Infants dependent on opioids, either through maternal or iatrogenic exposure, undergo neonatal opioid withdrawal syndrome (NOWS), where they may experience withdrawal symptoms ranging from mild to severe. We present a detailed and original review of NOWS caused by maternal opioid exposure (mNOWS) and iatrogenic opioid intake (iNOWS). While these two entities have been assessed entirely separately, recognition and treatment of the clinical manifestations of NOWS overlap. Neonatal risk factors such as age, genetic predisposition, drug type, and clinical factors like type of opioid, cumulative dose of opioid exposure, and disease status affect the incidence of both mNOWS and iNOWS, as well as their severity. Recognition of withdrawal is dependent on clinical assessment of symptoms, and the use of clinical assessment tools designed to determine the need for pharmacotherapy. Treatment of NOWS relies on a combination of non-pharmacological therapies and pharmacological options. Long-term consequences of opioids and NOWS continue to generate controversy, with some evidence of anatomic brain changes, but conflicting animal and human clinical evidence of significant cognitive or behavioral impacts on school-age children. We highlight the current knowledge on clinically relevant recognition, treatment, and consequences of NOWS, and identify new advances in clinical management of the neonate. This review brings a unique clinical perspective and critically analyzes gaps between the clinical problem and our preclinical understanding of NOWS.

Abstract
Like morphine, methadone is a pure agonist at the µ opioid receptor. However, in distinction to morphine which has an elimination half-life of 2-3 h, methadone has an elimination half-life of 24-36 h. In addition to its effects at the µ opioid receptor, methadone is an antagonist at the N-methyl-D-aspartate (NMDA) receptor and also inhibits the reuptake of the neurotransmitters, serotonin and norepinephrine, in the central nervous system. Given its long half-life and high oral bioavailability, methadone has had a primary role in the outpatient treatment of patients with a history of opioid abuse or addiction. However, its unique pharmacology and cellular effects make it a valuable agent in the treatment of both acute and chronic pain of various etiologies. The following manuscript reviews the pharmacologic properties of methadone and discusses its clinical applications in the practice of pediatric anesthesiology and pediatric critical care medicine.

Abstract
OBJECTIVE Determine if a standardized methadone and lorazepam weaning protocol that is based on dose and duration of exposure can reduce the length of opioid and benzodiazepine weaning and shorten hospital stay. METHODS Retrospective cohort study performed in a 24-bed medical/surgical PICU. A total of 177 patients on opioid and/or benzodiazepine infusions for >3 days were included; 75 patients pre protocol (June 2012- June 2013) were compared with 102 patients post implementation of a standardized weaning protocol of methadone and lorazepam (March 2014-March 2015). The recommended wean was based on duration of infusions of >3 days up to 5 days (no wean), 5 to 13 days (short wean), and ≥14 days (long wean). RESULTS Median number of days on methadone for patients on opioid infusions for 5 to 13 days was reduced from 8.5 to 5.7 days (p = 0.001; n = 45 [pre], n = 68 [post]) and for patients on opioid infusions for ≥14 days, from 29.7 to 11.5 days (p = 0.003; n = 9 [pre], n = 9 [post]) after protocol implementation. The median number of days on lorazepam for patients on benzodiazepine infusions for 5 to 13 days was reduced from 8.1 to 5.2 days (p = 0.020; n = 43 [pre], n = 55 [post]) and for patients on benzodiazepine infusions for ≥14 days, from 27.4 to 9.3 days (p = 0.011; n = 9 [pre], n = 8 [post]). There was no difference in methadone or lorazepam wean length for patients on 3 to 5 days of infusions. There was no difference in adverse events or hospital length of stay. CONCLUSIONS A methadone and lorazepam weaning protocol based on patient's exposure to opioids and benzodiazepines (dose and duration) reduces weaning length.

Abstract
BACKGROUND Critically ill patients are at high risk of iatrogenic withdrawal syndrome (IWS), due to exposure to high doses or prolonged periods of opioids and benzodiazepines. PURPOSE To examine pharmacological management strategies designed to prevent and/or treat IWS from opioids and/or benzodiazepines in critically ill neonates, children and adults. METHODS We included non-randomised studies of interventions (NRSI) and randomised controlled trials (RCTs), reporting on interventions to prevent or manage IWS in critically ill neonatal, paediatric and adult patients. Database searching included: PubMed, CINAHL, Embase, Cochrane databases, TRIP, CMA Infobase and NICE evidence. Additional grey literature was examined. Study selection and data extraction were performed in duplicate. Data collected included: population, definition of opioid, benzodiazepine or mixed IWS, its assessment and management (drug or strategy, route of administration, dosage and titration), previous drug exposures and outcomes measures. Methodological quality assessment was performed by two independent reviewers using the Cochrane risk of bias tool for RCTs and the ROBINS-I tool for NRSI. A qualitative synthesis of the results is provided. For the subset of studies evaluating multifaceted protocolised care, we meta-analysed results for 4 outcomes and examined the quality of evidence using GRADE post hoc. RESULTS Thirteen studies were eligible, including 10 NRSI and 3 RCTs; 11 of these included neonatal and paediatric patients exclusively. Eight studies evaluated multifaceted protocolised interventions, while 5 evaluated individual components of IWS management (e.g. clonidine or methadone at varying dosages, routes of administration and duration of tapering). IWS was measured using an appropriate tool in 6 studies. Ten studies reported upon occurrence of IWS, showing significant reductions (n = 4) or no differences (n = 6). Interventions failed to impact duration of mechanical ventilation, ICU length of stay, and adverse effects. Impact on opioid and/or benzodiazepine total doses and duration showed no differences in 4 studies, while 3 showed opioid and benzodiazepine cumulative doses were significantly reduced by 20-35% and 32-66%, and treatment durations by 1.5-11 and 19 days, respectively. Variable effects on intervention drug exposures were found. Weaning durations were reduced by 6-12 days (n = 4) for opioids and/or methadone and by 13 days (n = 1) for benzodiazepines. In contrast, two studies using interventions centred on transition to enteral routes or longer tapering durations found significant increases in intervention drug exposures. Interventions had overall non-significant effects on additional drug requirements (except for one study). Included studies were at high risk of bias, relating to selection, detection and reporting bias. CONCLUSION Interventions for IWS management fail to impact duration of mechanical ventilation or ICU length of stay, while effect on occurrence of IWS and drug exposures is inconsistent. Heterogeneity in the interventions used and methodological issues, including inappropriate and/or subjective identification of IWS and bias due to study design, limited the conclusions.

Abstract
OBJECTIVE Opioid abstinence syndrome is common in the pediatric intensive care environment because sedation is often needed during the children's treatment. There is no specific guideline regarding the management of these patients; and lately, methadone is an important drug for the prevention of abstinence symptoms during the weaning of opioids. This study gathers the available research to establish the initial dose of methadone, the rate of taper and tools to recognize this syndrome and act promptly. METHODS A systematic review was made from data of four different databases. Forty-nine articles of observational and experimental studies were selected based on the inclusion criteria (critical pediatric patients in acute use of opioids) and exclusion criteria (previous chronic use of opioids, other medications). The data regarding specific themes were separated in sections: initial dose of methadone, use of protocols in clinical practice, abstinence scales and adjuvant drugs. RESULTS The articles showed a great heterogeneity of ways to calculate the initial dose of methadone. The pediatric intensive care units of the study had different weaning protocols, with a lower incidence of abstinence when a pre-defined sequence of tapering was used. The Withdrawal Assessment Tool - 1 was the most used scale for tapering the opioids, with good sensitivity and specificity for signs and symptoms. CONCLUSION There is still little evidence of other medications that can help prevent the abstinence syndrome of opioids. This study tries to promote a better practice during opioid weaning.

Abstract
Supplemental Digital Content is available in the text. Introduction: Methadone and lorazepam prescribing discrepancies for the use of iatrogenic withdrawal were observed among providers. A standardized pharmacist-managed methadone and lorazepam taper protocol was implemented at a pediatric tertiary care facility with the aim to reduce the length of taper for patients with iatrogenic withdrawal. Methods: A multidisciplinary team of nurses, pharmacists, and physicians reviewed the current literature, then developed and implemented a standardized withdrawal taper protocol. Outcomes were compared with a retrospective control group using past prescribing practices. The primary endpoint was the length of methadone and/or lorazepam taper. Secondary endpoints included evaluation for significant differences between the control and standardized protocol groups regarding additional breakthrough withdrawal medications, pediatric intensive care unit (PICU) and hospital length of stay. We also evaluated provider satisfaction with the protocol. Results: The standardized protocol group included 25 patients who received methadone and/or lorazepam taper. A retrospective control group contained 24 patients. Median methadone taper length before protocol implementation was 9.5 days with an interquartile range (IQR) of 5.5–14.5 days; after protocol implementation, it was 6.0 (IQR, 3.0–9.0) days (P = 0.0145). Median lorazepam taper length before protocol implementation was 13.0 (IQR, 8.0–18.0) days; after protocol implementation, it was 6.0 (4.0–7.0) days (P = 0.0006). A statistical difference between PICU length of stay, hospital length of stay, or the number of additional medications for breakthrough withdrawal was not found. Conclusions: The use of a standardized withdrawal protocol resulted in shorter taper duration for both the methadone and lorazepam groups. There was no difference in PICU or hospital length of stay.

Abstract
Pediatric opioid and benzodiazepine withdrawal are avoidable complications of pain and sedation management that is well described in the literature. To prevent withdrawal from occurring, practitioners regularly use a steady decrease of pain and sedation medications, also known as a weaning or tapering schedule. The weaning schedule is highly variable based on clinician preference and is usually dependent on the clinician. The purposes of this review are to evaluate the current literature on the process of opioid and benzodiazepine weaning in pediatric patients and to assess the various standardized protocols used to decrease withdrawal occurrences. We conducted a search of the PubMed, MEDLINE, Cochrane Library, Cumulative Index of Nursing and Allied Health (CINAHL), Academic Search Premier, and PsycInfo databases. Studies were included if they described a wean or taper in pediatric patients aged 18 years or younger. Studies describing neonatal abstinence syndrome were excluded from the review. A total of 97 studies published between 2000 and 2014 were retrieved; of those, 15 studies met the inclusion criteria. Studies were evaluated for selection of withdrawal assessment tool, wean protocol summary, preferred weaning agents, benzodiazepine withdrawal, and wean-at-home regimen. The most common opioid-weaning protocol approaches described a 10-20% dose decrease per day. Benzodiazepine weaning was not regularly standardized or described. The use of a standardized opioid-weaning protocol reduced withdrawal rates compared with nonstandardized weaning plans. Benzodiazepine weaning was inconsistently evaluated and may have affected study outcomes. Identified areas of improvement include the use of newer withdrawal assessment tools validated in the older pediatric population and standardized withdrawal assessment and reporting.

Abstract
OBJECTIVES To identify available assessment tools for sedative/hypnotic iatrogenic withdrawal syndrome and delirium in PICU patients, the evidence supporting their use, and describe areas of overlap between the components of these tools and the symptoms of anticholinergic burden in children. DATA SOURCES Studies were identified using PubMed and EMBASE from the earliest available date until July 3, 2016, using a combination of MeSH terms "delirium," "substance withdrawal syndrome," and key words "opioids," "benzodiazepines," "critical illness," "ICU," and "intensive care." Review article references were also searched. STUDY SELECTION Human studies reporting assessment of delirium or iatrogenic withdrawal syndrome in children 0-18 years undergoing critical care. Non-English language, exclusively adult, and neonatal intensive care studies were excluded. DATA EXTRACTION References cataloged by study type, population, and screening process. DATA SYNTHESIS Iatrogenic withdrawal syndrome and delirium are both prevalent in the PICU population. Commonly used scales for delirium and iatrogenic withdrawal syndrome assess signs and symptoms in the motor, behavior, and state domains, and exhibit considerable overlap. In addition, signs and symptoms of an anticholinergic toxidrome (a risk associated with some common PICU medications) overlap with components of these scales, specifically in motor, cardiovascular, and psychiatric domains. CONCLUSIONS Although important studies have demonstrated apparent high prevalence of iatrogenic withdrawal syndrome and delirium in the PICU population, the overlap in these scoring systems presents potential difficulty in distinguishing syndromes, both clinically and for research purposes.

Abstract
BACKGROUND Continuous opioid infusion therapy is commonly utilized in the pediatric intensive care setting to treat pain and facilitate tolerance of invasive therapies. Transitioning to methadone is one common strategy for weaning from continuous opioid infusions, but in practice this transition can be challenging, and many children still experience iatrogenic withdrawal. AIM We reviewed the literature to evaluate the best available evidence to guide methadone therapy in this setting, and to summarize associated adverse events. METHODS We included all studies of methadone used to facilitate weaning from continuous opioid infusions in pediatric critical care patients, including medical, cardiac, and surgical patients, excluding case reports and studies treating neonatal abstinence syndrome, or acute or chronic pain. Medline, Embase, and CINAHL databases from inception to May 2015 were queried; references of included works and conference proceedings were also reviewed. Two authors independently extracted data from each study. Meta-analysis with fixed- and random-effects models was used to pool results of studies when applicable. RESULTS Twelve studies involving 459 patients met criteria for inclusion. A wide variety of methadone dosing and taper strategies were reported. Mean inpatient methadone taper times varied widely, from 4.3 to 26.2 days. Excessive sedation was the most frequently reported adverse event, occurring in up to 16% of patients. Withdrawal occurred in 27% of patients among studies reporting this outcome. In three of three studies in which a new methadone protocol was introduced, a decreased proportion of patients experienced withdrawal (standardized mean difference, SMD = -0.60, 95% CI = -0.998 to -0.195, P = 0.004). CONCLUSION We did not identify sufficient evidence to recommend any particular methadone weaning strategy, or to recommend methadone over other medications or prescribed infusion weaning, for successful weaning of continuous opioid infusions in the pediatric intensive care setting.

Abstract
Objective: Clinical Pharmacy Services (CPS) are considered standard of care and is endorsed
by the Joint Commission International, the American Academy of Pediatrics, and the
American College of Clinical Pharmacy. In Brazil, single experiences have been
discreetly arising and the importance of these services to children and
adolescents care has led to interesting results, but certainly are under reported.
This short report aims to discuss the effect of implementing a bedside CPS at a
Brazilian Pediatric Intensive Care Unit (PICU). Methods: This is a cross-sectional study conducted in a 12 bed PICU community hospital,
from Campo Largo/Brazil. Subjects with<18 years old admitted to PICU were
included for descriptive analysis if received a CPS intervention. Results: Of 53 patients accompanied, we detected 141 preventable drug-related problems
(DRPs) which were solved within clinicians (89% acceptance of all interventions).
The most common interventions performed to improve drug therapy included:
preventing incompatible intravenous solutions (21%) and a composite of inadequate
doses (17% due to low, high and non-optimized doses). Among the top ten
medications associated with DRPs, five were antimicrobials. By analyzing the
correlation between DRPs and PICU length of stay, we found that 74% of all
variations on length of stay were associated with the number of DRPs. Conclusions: Adverse drug reactions due to avoidable DRPs can be prevented by CPS in a
multifaceted collaboration with other health care professionals, who should
attempt to use active and evidence-based strategies to reduce morbidity related to
medications.

Abstract
Summary Introduction: Analgesia and sedation are essential elements in patient care in the intensive care unit (ICU), in order to promote the control of pain, anxiety and agitation, prevent the loss of devices, accidental extubation, and improve the synchrony of the patient with mechanical ventilation. However, excess of these medications leads to rise in morbidity and mortality. The ideal management will depend on the adoption of clinical and pharmacological measures, guided by scales and protocols. Objective: Literature review on the main aspects of analgesia and sedation, abstinence syndrome, and delirium in the pediatric intensive care unit, in order to show the importance of the use of protocols on the management of critically ill patients. Method: Articles published in the past 16 years on PubMed, Lilacs, and the Cochrane Library, with the terms analgesia, sedation, abstinence syndrome, mild sedation, daily interruption, and intensive care unit. Results: Seventy-six articles considered relevant were selected to describe the importance of using a protocol of sedation and analgesia. They recommended mild sedation and the use of assessment scales, daily interruptions, and spontaneous breathing test. These measures shorten the time of mechanical ventilation, as well as length of hospital stay, and help to control abstinence and delirium, without increasing the risk of morbidity and morbidity. Conclusion: Despite the lack of controlled and randomized clinical trials in the pediatric setting, the use of protocols, optimizing mild sedation, leads to decreased morbidity.

Abstract
IMPORTANCE Pediatric laryngotracheal reconstruction (LTR) remains the standard surgical technique for expanding a stenotic airway and necessitates a multidisciplinary team. Sedation wean following LTR is a critical component of perioperative care. We identified variation and communications deficiencies with our sedation wean practice and describe our experience implementing a standardized sedation wean protocol. OBJECTIVE To standardize and decrease length of sedation wean in pediatric patients undergoing LTR. DESIGN, SETTING, AND PARTICIPANTS Using Institute for Healthcare Improvement (IHI) methodology, we implemented systemwide change at a tertiary care center with the goal of improving care based on best practice guidelines. We created a standardized electronic sedation wean communication document and retrospectively examined our experience in 29 consecutive patients who underwent LTR before (n = 16, prewean group) and after (n = 13, postwean group) wean document implementation. INTERVENTIONS Implementation of a standardized sedation protocol. MAIN OUTCOMES AND MEASURES Presence of sedation wean document in the electronic medical record, length of sedation wean, and need for continued wean after discharge. RESULTS The sedation wean document was used in 92.3% patients in the postwean group. With the new process, the mean (SD) length of sedation wean was reduced from 16.19 (11.56) days in the prewean group to 8.92 (3.37) days in the postwean group (P = .045). Fewer patients in the postwean group required continued wean after discharge (81.3% vs 33.3%; P = .02). CONCLUSIONS AND RELEVANCE We implemented a systemwide process change with the goal of improving care based on best practice guidelines, which significantly decreased the time required for sedation wean following LTR. Our methodological approach may have implications for other heterogeneous patient populations requiring a sedation wean.
