RESUMO

BACKGROUND: Opioids are overprescribed in the outpatient dental setting. Therefore, opportunities exist for opioid stewardship. OBJECTIVES: The purpose of this pilot study was to test the feasibility of an academic detailing (AD) intervention to promote appropriate prescribing of opioids in outpatient dentistry. METHODS: We implemented an AD intervention targeting management of acute oral pain in a Midwestern Veterans Affairs outpatient dental facility. The intervention targeted dentists who actively prescribed opioids at the time of the study. The pilot study tested feasibility, adoption, and acceptance of the AD campaign. Visit-based prescribing rates were obtained from the Veterans Health Administration's Corporate Data Warehouse for baseline and postintervention using difference-in-differences analyses to detect potential changes in health service outcomes. RESULTS: Results indicate moderate levels of feasibility through participation rates (n = 5, 55.5%) and high levels of organizational readiness for change (average of 88.6% agree to strongly agree). Furthermore, fidelity of the AD intervention was high. Adoption measures show moderate indication of motivation to change, and trends suggest that participating dentists decreased their visit-based opioid prescribing rates (P > 0.05). CONCLUSION: The intervention demonstrated feasibility with some indications of adoption of intervention techniques and decrease in opioid prescribing. We further recommend working closely with frontline providers to gather feedback and buy-in before scaling and implementing the AD campaign.

RESUMO

Interprofessional teamwork plays a key role in the uptake of evidence-based interventions, such as noninvasive ventilation (NIV) for patients with exacerbated Chronic Obstructive Pulmonary Disease (COPD). We aimed to identify the shared cognitive tasks in interprofessional teams using NIV for patients with COPD exacerbation. We used a cognitive task analysis approach (CTA) to engage nurses, rapid response team members, respiratory therapists, and physicians involved in the use of NIV to treat patients with COPD exacerbation. Clinicians participated in a semi-structured interview (n = 21) that elicited cognitions needed to treat COPD exacerbation. Three shared cognitive tasks were identified: Complete a thorough assessment, Formulate a care plan, and Continuously monitor patient status. Findings attest to the importance of having access to up-to-date information and expertise necessary to make accurate clinical inferences for patient assessment. Shared understanding of the formulated care plan among all members of the care team was important to its execution. Continuous monitoring was crucial; however, this cognitive task relied on patient assessment skills and ongoing collaboration within the clinical care team. Application of NIV for patients with COPD exacerbation may require enhancing collaboration through nontechnical skills and interprofessional training.

RESUMO

Prior studies analyzing patient experience with noninvasive ventilation (NIV) found the most impactful interaction that patients remembered was with nurses, however a survey of nurses regarding the management of patients treated with NIV has shown that most nurses felt unprepared to care for these sick patients. Our qualitative descriptive study explored the current nursing experience using NIV as a treatment for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Nine (n = 9) subject matter expert nurses practicing in a variety of clinical settings participated in semi-structured interviews. The COnsolidated criteria for REporting Qualitative research checklist was followed for interview development. Interview transcripts were subsequently analyzed using deductive thematic analysis. Themes identified from the interviews pertained to patient assessment, novice nurses' need for clinical support, team communication, and nursing education. Improving interprofessional team communication and collaboration skills, and implementing guidelines for NIV utilization were specified as essential components of NIV education for nurses. Even though the nursing role in the care of AECOPD NIV patient could be institution dependent, the themes presented in our study are useful in identifying opportunities for NIV nursing education and areas for further research. Patient or Public Contribution: Nurses served as interviewees for this study.

RESUMO

OBJECTIVE: The purpose of this study is to uncover and catalog the various practices for delivering and disseminating clinical performance in various Veterans Affairs (VA) locations and to evaluate their quality against evidence-based models of effective feedback as reported in the literature. BACKGROUND: Feedback can enhance clinical performance in subsequent performance episodes. However, evidence is clear that the way in which feedback is delivered determines whether performance is harmed or improved. METHOD: We purposively sampled 16 geographically dispersed VA hospitals based on high, low, consistently moderate, and moderately average highly variable performance on a set of 17 outpatient clinical performance measures. We excluded four sites due to insufficient interview data. We interviewed four key personnel from each location (n = 48) to uncover effective and ineffective audit and feedback strategies. Interviews were transcribed and analyzed qualitatively using a framework-based content analysis approach to identify emergent themes. RESULTS: We identified 102 unique strategies used to deliver feedback. Of these strategies, 64 (62.74%) have been found to be ineffective according to the audit-and-feedback research literature. Comparing features common to effective (e.g., individually tailored, computerized feedback reports) versus ineffective (e.g., large staff meetings) strategies, most ineffective strategies delivered feedback in meetings, whereas strategies receiving the highest effectiveness scores delivered feedback via visually understood reports that did not occur in a group setting. CONCLUSIONS: Findings show that current practices are leveraging largely ineffective feedback strategies. Future research should seek to identify the longitudinal impact of current feedback and audit practices on clinical performance. APPLICATION: Feedback in primary care has little standardization and does not follow available evidence for effective feedback design. Future research in this area is warranted.

RESUMO

PURPOSE: To gain a deeper understanding of RNs communication related to patient safety. RESEARCH AIMS: To determine: (1) the associations between the communication of registered nurses (RNs) within their health care teams and the frequency that they reported safety events; (2) the associations between RNs' communication within their health care teams and their perceptions of safety within the hospital unit; and (3) whether RNs' communication had improved from 2016 to 2018. THEORETICAL FRAMEWORK AND METHODS: We used the United Kingdom's Safety Culture model as the theoretical framework for this study. Our secondary data analysis from the Agency for Healthcare Research and Quality's Hospital Survey on Patient Safety Culture included 2016 (n = 5298) and 2018 (n = 3476) using multiple regression models to determine associations between responses for Communication Openness and Feedback & Communication About Error, and outcome responses for Frequency of Events Reported and Overall Perceptions of Safety. RESULTS: Our findings were: 1). In both 2016 and 2018 datasets, Feedback About Error had a greater impact on Reporting Frequency than Open Communication; 2). Feedback About Error had a greater impact on Safety Perceptions than Open Communication; 3). Open Communication and Feedback About Error and their associations with Reporting Frequency and Safety Perceptions showed little change; and, 4). The proportion of variance was low, indicating factors other than Open Communication and Feedback About Error were involved with Reporting Frequency and Safety Perceptions. CONCLUSION: Pediatric RNs' communication, reporting, and perceptions of patient safety have not improved. (245 words).

RESUMO

The urgency to develop a vaccine against the 2019 coronavirus (COVID-19) has waxed stronger in speed, scale, and scope. However, wisdom dictates that we take a vantage position and start to examine the demographic predictors of COVID-19 vaccine hesitancy. The objective of this study was to examine the role of health locus of control (HLOC) in the relationship between religiosity and COVID-19 vaccination intention. In a cross-sectional survey (N = 501), we found a significantly negative association between religiosity and COVID-19 vaccination intention. This relationship was partially mediated by external HLOC. Collaborative efforts with religious institutions may influence COVID-19 vaccine uptake.

RESUMO

Resolving the structural dynamics of the initial steps of chemical reactions is challenging. We report the femtosecond time-resolved wide-angle x-ray scattering of the photodissociation of diiodomethane in cyclohexane. The data reveal with structural detail how the molecule dissociates into radicals, how the radicals collide with the solvent, and how they form the photoisomer. We extract how translational and rotational kinetic energy is dispersed into the solvent. We also find that 85% of the primary radical pairs are confined to their original solvent cage and discuss how this influences the downstream recombination reactions.

RESUMO

OBJECTIVE: The purpose of this meta-analytic review is to examine the role of three work environment support variables (i.e., peer, supervisor, and organizational support) in training transfer and sustainment or long-term use of learned knowledge, skills, and attitudes (KSAs). BACKGROUND: Estimates demonstrate that little training is transferred to the job, wasting billions in organizational spending each year and resulting in significant loss to safety and individual and team performance. Prior research shows the importance of a supportive work environment to facilitating transfer; however, we know little of the relative importance of specific support variables. This study seeks to examine the unique roles of distinct support variables in training transfer. METHOD: A meta-analysis was conducted with multiple regressions to answer three primary research questions. RESULTS: All work environment support variables demonstrate moderate and positive correlations with transfer of training. Furthermore, multiple regressions demonstrate that each factor of the work environment explains unique variance as a predictor, with the model accounting for 32% of transfer and peer support accounting for most of R2. Motivation to transfer mediates the relationship between all three work environment support variables and transfer. Furthermore, three support variables are positively related to sustainment, with peer and supervisor support showing the strongest relationships. CONCLUSION: Findings illuminate the relative contribution of peer, supervisor, and organizational support to transfer and sustainment of training. As transfer continues to be an important yet understudied measure of the effectiveness of workplace training, these findings hold implications for both research and practice.

RESUMO

Phytochromes are photoreceptors in plants, fungi, and various microorganisms and cycle between metastable red light-absorbing (Pr) and far-red light-absorbing (Pfr) states. Their light responses are thought to follow a conserved structural mechanism that is triggered by isomerization of the chromophore. Downstream structural changes involve refolding of the so-called tongue extension of the phytochrome-specific GAF-related (PHY) domain of the photoreceptor. The tongue is connected to the chromophore by conserved DIP and PRXSF motifs and a conserved tyrosine, but the role of these residues in signal transduction is not clear. Here, we examine the tongue interactions and their interplay with the chromophore by substituting the conserved tyrosine (Tyr263) in the phytochrome from the extremophile bacterium Deinococcus radiodurans with phenylalanine. Using optical and FTIR spectroscopy, X-ray solution scattering, and crystallography of chromophore-binding domain (CBD) and CBD-PHY fragments, we show that the absence of the Tyr263 hydroxyl destabilizes the ß-sheet conformation of the tongue. This allowed the phytochrome to adopt an α-helical tongue conformation regardless of the chromophore state, hence distorting the activity state of the protein. Our crystal structures further revealed that water interactions are missing in the Y263F mutant, correlating with a decrease of the photoconversion yield and underpinning the functional role of Tyr263 in phytochrome conformational changes. We propose a model in which isomerization of the chromophore, refolding of the tongue, and globular conformational changes are represented as weakly coupled equilibria. The results also suggest that the phytochromes have several redundant signaling routes.

RESUMO

Lysine specific demethylase 1 (LSD1) is a histone modifying enzyme that suppresses gene expression through demethylation of lysine 4 on histone H3. The anti-tumor activity of GSK2879552 and GSK-LSD1, potent, selective irreversible inactivators of LSD1, has previously been described. Inhibition of LSD1 results in a cytostatic growth inhibitory effect in a range of acute myeloid leukemia cell lines. To enhance the therapeutic potential of LSD1 inhibition in this disease setting, a combination of LSD1 inhibition and all-trans retinoic acid was explored. All-trans retinoic acid is currently approved for use in acute promyelocytic leukemia in which it promotes differentiation of abnormal blast cells into normal white blood cells. Combined treatment with all-trans retinoic acid and GSK2879552 results in synergistic effects on cell proliferation, markers of differentiation, and, most importantly, cytotoxicity. Ultimately the combination potential for LSD1 inhibition and ATRA will require validation in acute myeloid leukemia patients, and clinical studies to assess this are currently underway.

RESUMO

OBJECTIVE: We aimed to provide an assessment of the impact of workload manipulations on various cardiac measurements. We further sought to determine the most effective measurement approaches of cognitive workload as well as quantify the conditions under which these measures are most effective for interpretation. BACKGROUND: Cognitive workload affects human performance, particularly when load is relatively high (overload) or low (underload). Despite ongoing interest in assessing cognitive workload through cardiac measures, it is currently unclear which cardiac-based assessments best indicate cognitive workload. Although several quantitative studies and qualitative reviews have sought to provide guidance, no meta-analytic integration of cardiac assessment(s) of cognitive workload exists to date. METHOD: We used Morris and DeShon's meta-analytic procedures to quantify the changes in cardiac measures due to task load conditions. RESULTS: Sample-weighted Cohen's d values suggest that several metrics of cardiac activity demonstrate sensitivity in response to cognitive workload manipulations. Heart rate variability measures show sensitivity to task load, conditions of event rate, and task duration. Authors of future work should seek to quantify the utility of leveraging multiple metrics to understand workload. CONCLUSION: Results suggest that assessment of cognitive workload can be done using various cardiac activity indicators. Further, given the number of valid and reliable measures available, researchers and practitioners should base their selection of a psychophysiological measure on the experimental and practical concerns inherent to their task/protocol. APPLICATIONS: Findings bear implications for future assessment of cognitive workload within basic and applied settings. Future research should seek to validate conditions under which measurements are best interpreted, including but not limited to individual differences.

RESUMO

OBJECTIVES: Our aim was to determine whether emergency physicians (EPs) felt their standard patient evaluation practice was modified by two non-private clinical encounters: hallway encounters and encounters during which a companion was present. METHODS: We administered an iteratively developed cross-sectional survey at an annual national professional meeting. We used logistic regression to compare relationships among non-private clinical encounters and predictors of interest. RESULTS: 409 EPs completed the survey. EPs deviated from standard history-taking when practising in a hallway location (78%) and when patients had a companion (84%). EPs altered their standard physical exam when practising in a hallway location (90%) and when patients had a companion (77%). EPs with at least a decade of experience were less likely to alter history-taking in the hallway (OR 0.55, 95% CI 0.31 to 0.99). Clinicians who frequently evaluated patients in the hallway reported delays or diagnostic error-related to altered history-taking (OR 2.34, 95% CI 1.33 to 4.11). The genitourinary system was the most common organ system linked to a delay or diagnostic error. Modifications in history-taking were linked to delays or failure to diagnose suicidal ideation or self-harm (25%), intimate partner violence (40%), child abuse (12%), human trafficking (8%), substance abuse (47%) and elder abuse (17%). CONCLUSIONS: Our study suggests that alterations in EP usual practice occurs when the doctor-patient dyad is disrupted by evaluation in a hallway or presence of a companion. Furthermore, these disruptions are associated with delays in care and failure to diagnosis medical, social and psychiatric conditions.

RESUMO

OBJECTIVE: The current pilot study aimed to assess whether reporting quality would decline materially in adolescents completing weekly web-based Automated Self-Administered 24-Hour dietary recalls (ASA24-Kids-2014) and interviewer-administered 24 h dietary recalls for six weeks. We also aimed to assess method preference. DESIGN: We conducted two studies. Study 1 (n 20) randomized participants to complete either one ASA24-Kids-2014 or one interviewer-administered recall weekly, for six weeks. Energy intake and number of foods reported were described for each method over time. Differences between recall methods for each measure were tested using mixed-effects regression. Study 2 (n 10) employed a randomized crossover design to describe method preference. SETTING: Dietary intake was collected either by telephone (interviewer-administered dietary recalls) or via the Internet (ASA24-Kids-2014 dietary recalls). SUBJECTS: Adolescents aged 12-17 years with no prior diet recording experience were enrolled. RESULTS: In Study 1, mean (sd) total energy and number of foods reported decreased by 50 (222) kJ (12 (53) kcal) and 0·05 (0·31) items v. 38 (138) kJ (9 (33) kcal) and 0·17 (0·14) items per recall for participants randomized to the ASA24-Kids-2014 v. interviewer-administered recalls, respectively. There was no difference between groups for either measure (P > 0·57). In Study 2, eight of ten participants preferred the interviewer-administered recall over the ASA24-Kids-2014. Overall, seven of twenty participants experienced technical difficulties with the ASA24-Kids-2014. CONCLUSIONS: No appreciable decay in reporting quality was seen for either method. However, participants reported a preference for the interviewer-administered recall. Our findings can help inform and support larger studies to further characterize the performance of the ASA24 in adolescents.

RESUMO

BACKGROUND: As a result of the recent proliferation of health care team training (HTT), there was a need to update previous systematic reviews examining the underlying structure driving team training initiatives. METHODS: This investigation was guided by 10 research questions. A literature search identified 197 empirical samples detailing the evaluation of team training programs within the health care context; 1,764 measures of HTT effectiveness were identified within these samples. Trained coders extracted information related to study design and training development, implementation, and evaluation to calculate percentages detailing the prevalence of certain training features. RESULTS: HTT was rarely informed by a training needs analysis (k = 47, 23.9%) and most commonly addressed communication strategies (k = 167, 84.8%). HTT programs that incorporated practice (k = 163, 82.7%) often employed high-fidelity patient simulators (k = 38, 25.2%) and provided participants with feedback opportunities (k = 107, 65.6%). Participants were typically practicing clinicians (k = 154, 78.2%) with a lower prevalence of health care students (k = 35, 17.8). Evaluations primarily relied on repeated measures designs (k = 123, 62.4%) and self-reported data (k = 1,257, 71.3%). Additional trends were identified and are discussed. CONCLUSIONS: Many trends in HTT practice and evaluation were identified. The results of this review suggested that, in the literature, HTT programs are more frequently following recommendations for training design and implementation (for example, providing feedback) in comparison to findings from previous reviews. However, there were still many areas in which improvement could be achieved to improve patient care.

RESUMO

Objective The aim of this study was to describe the relationship between negative affect (NA), decision-making style, time stress, and decision quality in health care. Background Health care providers must often make swift, high-stakes decisions. Influencing factors of the decision-making process in this context have been understudied. Method Within a sample of labor and delivery nurses, physicians, and allied personnel, we used self-report measures to examine the impact of trait factors, including NA, decision-making style, and perceived time stress, on decision quality in a situational judgment test (Study 1). In Study 2, we observed the influence of state NA, state decision-making style, state time stress, and their relationship with decision quality on real clinical decisions. Results In Study 1, we found that trait NA significantly predicted avoidant decision-making style. Furthermore, those who were higher on trait time stress and trait avoidant decision-making style exhibited poorer decisions. In Study 2, we observed associations between state NA with state avoidant and analytical decision-making styles. We also observed that these decision-making styles, when considered in tandem with time stress, were influential in predicting clinical decision quality. Conclusion NA predicts some decision-making styles, and decision-making style can affect decision quality under time stress. This is particularly true for state factors. Application Individual differences, such as affect and decision-making style, should be considered during selection. Training to reduce time stress perceptions should be provided.

RESUMO

INTRODUCTION: Increased teammate familiarity in emergency medical services (EMS) promotes development of positive teamwork and protects against workplace injury. METHODS: Measures were collected using archival shift records, workplace injury data, and cross-sectional surveys from a nationally representative sample of 14 EMS agencies employing paramedics, prehospital nurses, and other EMS clinicians. One thousand EMS clinicians were selected at random to complete a teamwork survey for each of their recent partnerships and tested the hypothesized role of teamwork as a mediator in the relationship between teammate familiarity and injury with the PROCESS macro. RESULTS: We received 2566 completed surveys from 333 clinicians, of which 297 were retained. Mean participation was 40.5% (standard deviation [SD] = 20.5%) across EMS agencies. Survey respondents were primarily white (93.8%), male (67.3%), and ranged between 21-62 years of age (M = 37.4, SD = 9.7). Seventeen percent were prehospital nurses. Respondents worked a mean of 3 shifts with recent teammates in the 8 weeks preceding the survey (M = 3.06, SD = 4.4). We examined data at the team level, which suggest positive views of teamwork (M = 5.92, SD = 0.69). Our hypothesis that increased teammate familiarity protects against adverse safety outcomes through development of positive teamwork was not supported. Teamwork factor Partner Adaptability and Backup Behavior is a likely mediator (odds ratio = 1.03, P = .05). When dyad familiarity is high and there are high levels of backup behavior, the likelihood of injury is increased. DISCUSSION: The relationship between teammate familiarity and outcomes is complex. Teammate adaptation and backup behavior is a likely mediator of this relationship in EMS teams with greater familiarity.

RESUMO

OBJECTIVE: We investigated the association between teammate familiarity and workplace injury in the emergency medical services (EMS) setting. METHODS: From January 2011 to November 2013, we abstracted a mean of 29 months of shift records and Occupational Safety Health Administration injury logs from 14 EMS organisations with 37 total bases located in four US Census regions. Total teammate familiarity was calculated for each dyad as the total number of times a clinician dyad worked together over the study period. We used negative binomial regression to examine differences in injury incidence rate ratios (IRRs) by familiarity. RESULTS: We analysed 715 826 shift records, representing 4197 EMS clinicians and 60 701 unique dyads. We determined the mean shifts per dyad was (5.9, SD 19.7), and quartiles of familiarity were 1 shift worked together over the study period, 2-3 shifts, 4-9 shifts and ≥10 shifts worked together. More than half of all dyads worked one shift together (53.9%, n=32 739), 24.8% of dyads 2-3 shifts, 11.8% worked 4-9 shifts and 9.6% worked ≥10 shifts. The overall incidence rate of injury across all organisations was 17.5 per 100 full-time equivalent (FTE), range 4.7-85.6 per 100 FTE. The raw injury rate was 33.5 per 100 FTEs for dyads with one shift of total familiarity, 14.2 for 2-3 shifts, 8.3 for 4-9 shifts and 0.3 for ≥10 shifts. Negative binomial regression confirmed that dyads with ≥10 shifts had the lowest incidence of injury (IRR 0.03; 95% CI 0.02 to 0.04). CONCLUSIONS: Familiarity between teammates varies in the EMS setting, and less familiarity is associated with greater incidence of workplace injury.

RESUMO

Trimethylation of histone H3 on lysine 27 (H3K27me3) is a repressive posttranslational modification mediated by the histone methyltransferase EZH2. EZH2 is a component of the polycomb repressive complex 2 and is overexpressed in many cancers. In B-cell lymphomas, its substrate preference is frequently altered through somatic mutation of the EZH2 Y641 residue. Herein, we identify mutation of EZH2 A677 to a glycine (A677G) among lymphoma cell lines and primary tumor specimens. Similar to Y641 mutant cell lines, an A677G mutant cell line revealed aberrantly elevated H3K27me3 and decreased monomethylated H3K27 (H3K27me1) and dimethylated H3K27 (H3K27me2). A677G EZH2 possessed catalytic activity with a substrate specificity that was distinct from those of both WT EZH2 and Y641 mutants. Whereas WT EZH2 displayed a preference for substrates with less methylation [unmethylated H3K27 (H3K27me0):me1:me2 k(cat)/K(m) ratio = 9:6:1] and Y641 mutants preferred substrates with greater methylation (H3K27me0:me1:me2 k(cat)/K(m) ratio = 1:2:13), the A677G EZH2 demonstrated nearly equal efficiency for all three substrates (H3K27me0:me1:me2 k(cat)/K(m) ratio = 1.1:0.6:1). When transiently expressed in cells, A677G EZH2, but not WT EZH2, increased global H3K27me3 and decreased H3K27me2. Structural modeling of WT and mutant EZH2 suggested that the A677G mutation acquires the ability to methylate H3K27me2 through enlargement of the lysine tunnel while preserving activity with H3K27me0/me1 substrates through retention of the Y641 residue that is crucial for orientation of these smaller substrates. This mutation highlights the interplay between Y641 and A677 residues in the substrate specificity of EZH2 and identifies another lymphoma patient population that harbors an activating mutation of EZH2.

RESUMO

BACKGROUND: The aim of this study was to examine the impact of a telemedical robot on trauma intensive care unit (TICU) clinician teamwork (i.e., team attitudes, behaviors, and cognitions) during patient rounds. MATERIALS AND METHODS: Thirty-two healthcare providers who conduct rounds volunteered to take surveys assessing teamwork attitudes and cognitions at three time periods: (1) the onset of the study, (2) the end of the 30-day control period, and (3) the end of the 30-day experimental period, which immediately followed the control period. Rounds were recorded throughout the 30-day control period and 30-day experimental period to observe provider behaviors. For the initial 30 days, there was no access to telemedicine. For the final 30 days, the rounding healthcare providers had access to the RP-7 robot (Intouch Health Inc., Santa Barbara, CA), a telemedical tool that can facilitate patient rounds conducted away from bedside. RESULTS: Using a one-tailed, one-way repeated-measures analysis of variance (ANOVA) to compare trust at Times 1, 2, and 3, there was no significant effect on trust: F(2, 14)=1.20, p=0.16. When a one-tailed, one-way repeated-measures ANOVA to compare transactive memory systems (TMS) at Times 1, 2, and 3 was conducted, there was no significant effect on TMS: F(2, 15)=1.33, p=0.15. We conducted a one-tailed, one-way repeated-measures ANOVA to compare team psychological safety at Times 1, 2, and 3, and there was no significant effect on team psychological safety: F(2,15)=1.53, p=0.12. There was a significant difference in communication between rounds with and without telemedicine [t(25)=-1.76, p<0.05], such that there was more task-based communication during telerounds. Telemedicine increased task-based communication and did not negatively impact team trust, psychological safety, or TMS during rounds. CONCLUSIONS: Telemedicine may offer advantages for some teamwork competencies without sacrificing the efficacy of others and may be adopted by intact rounding teams without hindering teamwork.

RESUMO

When administered as first-line intervention to patients admitted with acute hypercapnic respiratory failure secondary to COPD exacerbation in conjunction with guideline-recommended therapies, noninvasive ventilation (NIV) has been shown to reduce mortality and endotracheal intubation. Opportunities to increase uptake of NIV continue to exist despite inclusion of this therapy in clinical guidelines. Identifying patients appropriate for NIV, and subsequently providing close monitoring to determine an improvement in clinical condition involves a team consisting of physician, nurse, and respiratory therapist in institutions that successfully implement NIV. We describe to our knowledge the first known evidence-based algorithm speaking to initiation, titration, monitoring, and weaning of NIV in treatment of acute exacerbation of COPD that incorporates the necessary interprofessional collaboration among physicians, nurses, and respiratory therapists caring for these patients.
