RESUMEN
Importance: Physician turnover interrupts care delivery and creates health care system financial burden. Objective: To describe the prevalence of burnout, professional fulfillment, and intention to leave (ITL) among physicians at academic-affiliated health care systems and identify institutional and individual factors associated with ITL. Design, Setting, and Participants: This cross-sectional study administered a survey to 37 511 attending-level medical specialists at 15 academic medical institutions participating in the Healthcare Professional Well-Being Academic Consortium. Data were collected from October 2019 to July 2021. Statistical analysis was performed from May 2022 to March 2023. Exposures: Hypothesized institutional and individual determinants of occupational well-being. Main Outcomes and Measures: The main outcome was ITL, defined as having at least a moderate intention (a score of 2 on a 0-4 scale) to leave one's institution within the next 2 years. Additional outcomes included burnout and professional fulfillment, defined using published Professional Fulfillment Index cut points. Results: Of 18â¯719 academic physician survey respondents (8381 [44.8%] male; 2388 [12.8%] Asian, 10â¯599 [56.6%] White, 1039 [5.6%] other race, 4693 [25.1%] unknown race; 294 [1.6%] Hispanic or Latina/Latino/Latinx), 6903 of 18â¯217 (37.9%) met criteria for burnout and 7301 of 18â¯571 (39.3%) for professional fulfillment; 5177 of 15â¯890 (32.6%) reported moderate or greater ITL. Burnout, professional fulfillment, and ITL varied across specialties. After adjusting for demographics, each 1-point increase (range 0-10) in burnout was directly associated with ITL (odds ratio [OR], 1.52 [95% CI, 1.49-1.55])c, and each 1-point increase in professional fulfillment was inversely associated with ITL (OR, 0.64 [95% CI, 0.63-0.65]). After adjusting for demographics, burnout, and professional fulfillment, each 1-point increase (range 0-10) in supportive leadership behaviors (OR, 0.83 [95% CI, 0.82-0.84]), peer support (OR, 0.93 [95% CI, 0.91-0.95]), personal-organizational values alignment (OR, 0.81 [95% CI, 0.80-0.82]), perceived gratitude (OR, 0.95 [95% CI, 0.92-0.97]), COVID-19 organizational support (OR, 0.88 [95% CI, 0.85-0.91]), and electronic health record helpfulness (OR, 0.95 [95% CI, 0.93-0.97]) were inversely associated with ITL, whereas each 1-point increase (range 0-10) in depression (OR, 1.08 [95% CI, 1.05-1.10]) and negative impact of work on personal relationships (OR, 1.09 [1.07-1.11]) were directly associated with ITL. Conclusions and Relevance: In this cross-sectional study of academic physicians, 32.6% indicated moderate or higher ITL within 2 years. Burnout, lack of professional fulfillment, and other well-being factors were associated with ITL, suggesting the need for a comprehensive approach to reduce physician turnover.

Objectives: This study aimed to identify rates of and contributors to burnout and professional fulfillment among emergency medicine (EM) resident physicians. Methods: This was a cross-sectional, national survey of resident members of the Society for Academic Emergency Medicine (SAEM). Primary outcomes were burnout and professional fulfillment measured using a previously validated instrument with additional domains pertaining to the academic environment. The survey included question domains examining organizational factors (e.g., academic work environment, satisfaction with training, electronic health records, values alignment, and control over schedule) and individual factors (e.g., self-compassion, meaningfulness of clinical work, impact of work on health and personal relationships, perceived appreciation, thoughts of attrition, and expectations of the field of EM). Logistic regression was performed to determine the relationships between the primary outcomes and each domain. Results: The survey was sent electronically to 2641 SAEM resident members. A total of 275 residents completed the survey with a response rate of 10.4%. A total of 151 (55%) respondents were male, and 210 (76%) were White. A total of 132 (48%) residents reported burnout, and 75 (28%) reported professional fulfillment. All organizational and individual factors were significantly associated with both primary outcomes. EM residents reported that meaningfulness of clinical work had the most significant positive association with professional fulfillment (adjusted odds ratio [OR] 2.2 [95% confidence interval {CI} 1.8-2.7]) and negative association with burnout (adjusted OR 0.46 [95% CI 0.37-0.56]). Thoughts of attrition from academics and accurate expectations of EM were also associated with both primary outcomes, with adjusted ORs (95% CIs) of 0.40 (0.21-0.72) and 5.6 (1.9-23.8) for professional fulfillment and 4.1 (2.5-7.1) and 0.19 (0.08-0.40) for burnout, respectively. Conclusions: This study found a high prevalence of burnout and a low prevalence of professional fulfillment among EM residents. Multiple factors were significantly associated with each occupational phenomenon, with meaningfulness of clinical work demonstrating the strongest relationships with burnout and professional fulfillment.
RESUMEN
BACKGROUND: Professional fulfillment and the mitigation of burnout can enhance clinician well-being and the resiliency of the health care organization. This study examined the extent to which specific individual and workplace factors are associated with professional fulfillment and burnout among a national sample of academic emergency physicians. METHODS: This was a cross-sectional survey of faculty members of the Society for Academic Emergency Medicine. Primary outcomes were professional fulfillment and burnout. The survey also examined individual and workplace factors as well as faculty's thoughts of attrition from academic and clinical medicine. Logistic regression was performed to determine the relationships between each outcome and each factor, respectively. RESULTS: A total of 771 of 3130 faculty completed the survey (response rate 24.6%). A total of 38.7% reported professional fulfillment and 39.1% reported burnout. Meaningfulness of work (odds ratio [OR] 2.2, 95% confidence interval [CI] 1.9-2.5), perceived appreciation (OR 1.9, 95% CI 1.7-2.1), and the academic work environment (OR 1.7, 95% CI 1.5-1.9) had the highest odds of being associated with professional fulfillment. In contrast, low score responses for meaningfulness of work (OR 0.6, 95% CI 0.5-0.6), self-compassion (0.6, 95% CI 0.5-0.6), and control over schedule (OR 0.6, 95% CI 0.6-0.7) were most associated with burnout. Faculty with professional fulfillment were less likely to report plans for attrition from academics (OR 0.1, 95% CI 0.1-0.2) and from clinical medicine (OR 0.2, 95% CI 0.1-0.4). Faculty with burnout were more likely to report plans for attrition from academics (OR 7, 95% CI 4.8-10.4) and clinical medicine (OR 5.7, 95% CI 3.9-8.6). CONCLUSIONS: Individual and workplace factors that contributed to professional fulfillment and burnout were identified, with meaningfulness of clinical work demonstrating the strongest association with both occupational phenomena. Knowledge of which factors are most impactful in promoting professional fulfillment and mitigating burnout may be useful in guiding efforts to enhance clinician well-being.

Calls to change the residency selection process have increased in recent years, with many focusing on the need for holistic review and alternatives to academic metrics. One aspect of applicant performance to consider in holistic review is proficiency in behavioral competencies. The Association of American Medical Colleges (AAMC) developed the AAMC Standardized Video Interview (SVI), an online, asynchronous video interview that assesses applicants' knowledge of professionalism and their interpersonal and communication skills. The AAMC worked with the emergency medicine community to pilot the SVI. Data from 4 years of research (Electronic Residency Application Service [ERAS] 2017-2020 cycles) show the SVI is a reliable, valid assessment of these behavioral competencies. It provides information not available in the ERAS application packet, and it does not disadvantage individuals or groups. Yet despite the SVI's psychometric properties, the AAMC elected not to renew or expand the pilot in residency selection.In this Invited Commentary, the authors share lessons learned from the AAMC SVI project about introducing a new tool for use in residency selection. They recommend that future projects endeavoring to find ways to support holistic review engage all stakeholders from the start; communicate the value of the new tool early and often; make direct comparisons with existing tools; give new tools time and space to succeed; strike a balance between early adopters and broad participation; help stakeholders understand the limitations of what a tool can do; and set clear expectations about both stakeholder input and pricing. They encourage the medical education community to learn from the SVI project and to consider future partnerships with the AAMC or other specialty organizations to develop new tools and approaches that prioritize the community's needs. Finding solutions to the challenges facing residency selection should be a priority for all stakeholders.

OBJECTIVE: This systematic review focused on randomized controlled trials (RCTs) with physicians and nurses that tested interventions designed to improve their mental health, well-being, physical health, and lifestyle behaviors. DATA SOURCE: A systematic search of electronic databases from 2008 to May 2018 included PubMed, CINAHL, PsycINFO, SPORTDiscus, and the Cochrane Library. STUDY INCLUSION AND EXCLUSION CRITERIA: Inclusion criteria included an RCT design, samples of physicians and/or nurses, and publication year 2008 or later with outcomes targeting mental health, well-being/resiliency, healthy lifestyle behaviors, and/or physical health. Exclusion criteria included studies with a focus on burnout without measures of mood, resiliency, mindfulness, or stress; primary focus on an area other than health promotion; and non-English papers. DATA EXTRACTION: Quantitative and qualitative data were extracted from each study by 2 independent researchers using a standardized template created in Covidence. DATA SYNTHESIS: Although meta-analytic pooling across all studies was desired, a wide array of outcome measures made quantitative pooling unsuitable. Therefore, effect sizes were calculated and a mini meta-analysis was completed. RESULTS: Twenty-nine studies (N = 2708 participants) met the inclusion criteria. Results indicated that mindfulness and cognitive-behavioral therapy-based interventions are effective in reducing stress, anxiety, and depression. Brief interventions that incorporate deep breathing and gratitude may be beneficial. Visual triggers, pedometers, and health coaching with texting increased physical activity. CONCLUSION: Healthcare systems must promote the health and well-being of physicians and nurses with evidence-based interventions to improve population health and enhance the quality and safety of the care that is delivered.

PURPOSE: This study examined applicant reactions to the Association of American Medical Colleges Standardized Video Interview (SVI) during its first year of operational use in emergency medicine (EM) residency program selection to identify strategies to improve applicants' SVI experience and attitudes. METHOD: Individuals who self-classified as EM applicants applying in the Electronic Residency Application Service 2018 cycle and who completed the SVI in summer 2017 were invited to participate in 2 surveys. Survey 1, which focused on procedural issues, was administered immediately after SVI completion. Survey 2, which focused on applicants' SVI experience, was administered in fall 2017, after SVI scores were released. RESULTS: The response rates for surveys 1 and 2 were 82.3% (2,906/3,532) and 58.7% (2,074/3,532), respectively. Applicant reactions varied by aspect of the SVI studied and their SVI total scores. Most applicants were satisfied with most procedural aspects of the SVI, but most applicants were not satisfied with the SVI overall or with their total SVI scores. About 20% to 30% of applicants had neutral opinions about most aspects of the SVI. Negative reactions to the SVI were stronger for applicants who scored lower on the SVI. CONCLUSIONS: Applicants had generally negative reactions to the SVI. Most were skeptical of its ability to assess the target competencies and its potential to add value to the selection process. Applicant acceptance and appreciation of the SVI will be critical to the SVI's acceptance by the graduate medical education community.

PURPOSE: Innovative tools are needed to shift residency selection toward a more holistic process that balances academic achievement with other competencies important for success in residency. The authors evaluated the feasibility of the AAMC Standardized Video Interview (SVI) and evidence of the validity of SVI total scores. METHOD: The SVI, developed by the Association of American Medical Colleges, consists of six questions designed to assess applicants' interpersonal and communication skills and knowledge of professionalism. Study 1 was conducted in 2016 for research purposes. Study 2 was an operational pilot administration in 2017; SVI data were available for use in residency selection by emergency medicine programs for the 2018 application cycle. Descriptive statistics, correlations, and standardized mean differences were used to examine data. RESULTS: Study 1 included 855 applicants; Study 2 included 3,532 applicants. SVI total scores were relatively normally distributed. There were small correlations between SVI total scores and United States Medical Licensing Examination Step exam scores, Alpha Omega Alpha Honor Medical Society membership, and Gold Humanism Honor Society membership. There were no-to-small group differences in SVI total scores by gender and race/ethnicity, and small-to-medium differences by applicant type. CONCLUSIONS: Findings provide initial evidence of the validity of SVI total scores and suggest that these scores provide different information than academic metrics. Use of the SVI, as part of a holistic screening process, may help program directors widen the pool of applicants invited to in-person interviews and may signal that programs value interpersonal and communication skills and professionalism.

PURPOSE: To evaluate how emergency medicine residency programs perceived and used Association of American Medical Colleges (AAMC) Standardized Video Interview (SVI) total scores and videos during the Electronic Residency Application Service 2018 cycle. METHOD: Study 1 (November 2017) used a program director survey to evaluate user reactions to the SVI following the first year of operational use. Study 2 (January 2018) analyzed program usage of SVI video responses using data collected through the AAMC Program Director's Workstation. RESULTS: Results from the survey (125/175 programs; 71% response rate) and video usage analysis suggested programs viewed videos out of curiosity and to understand the range of SVI total scores. Programs were more likely to view videos for attendees of U.S. MD-granting medical schools and applicants with higher United States Medical Licensing Examination Step 1 scores, but there were no differences by gender or race/ethnicity. More than half of programs that did not use SVI total scores in their selection processes were unsure of how to incorporate them (36/58; 62%) and wanted additional research on utility (33/58; 57%). More than half of programs indicated being at least somewhat likely to use SVI total scores (55/97; 57%) and videos (52/99; 53%) in the future. CONCLUSIONS: Program reactions on the utility and ease of use of SVI total scores were mixed. Survey results indicate programs used the SVI cautiously in their selection processes, consistent with AAMC recommendations. Future user surveys will help the AAMC gauge improvements in user acceptance and familiarity with the SVI.

Organophosphorus (OP) pesticide poisoning is a significant problem worldwide. Research into new antidotes for these acetylcholinesterase inhibitors, and even optimal doses for current therapies, is hindered by a lack of standardized animal models. In this study, we sought to characterize the effects of the OP pesticide parathion on acetylcholinesterase in a Wistar rat model that included comprehensive medical care. Methods. Male Wistar rats were intubated and mechanically ventilated and then poisoned with between 20 mg/kg and 60 mg/kg of intravenous parathion. Upon developing signs of poisoning, the rats were treated with standard critical care, including atropine, pralidoxime chloride, and midazolam, for up to 48 hours. Acetylcholinesterase activity was determined serially for up to 8 days after poisoning. Results. At all doses of parathion, maximal depression of acetylcholinesterase occurred at 3 hours after poisoning. Acetylcholinesterase recovered to nearly 50% of baseline activity by day 4 in the 20 mg/kg cohort and by day 5 in the 40 and 60 mg/kg cohorts. At day 8, most rats' acetylcholinesterase had recovered to roughly 70% of baseline. These data should be useful in developing rodent models of acute OP pesticide poisoning.
RESUMEN
Organophosphorus (OP) pesticide poisoning is a leading cause of morbidity and mortality in the developing world, affecting an estimated three million people annually. Much of the morbidity is directly related to muscle weakness, which develops 1-4 days after poisoning. This muscle weakness, termed the intermediate syndrome (IMS), leads to respiratory, bulbar, and proximal limb weakness and frequently necessitates the use of mechanical ventilation. While not entirely understood, the IMS is most likely due to persistently elevated acetylcholine (ACh), which activates nicotinic ACh receptors at the neuromuscular junction (NMJ). Thus, the NMJ is potentially a target-rich area for the development of new therapies for acute OP poisoning. In this manuscript, we discuss what is known about the IMS and studies investigating the use of nicotinic ACh receptor antagonists to prevent or mitigate NMJ dysfunction after acute OP poisoning.

BACKGROUND: Patient safety incident (PSI) discovery is an essential component of quality improvement. When submitted, incident reports may provide valuable opportunities for PSI discovery. However, little objective information is available to date to quantify or demonstrate this value. The objective of this investigation was to assess how often Emergency Department (ED) incident reports submitted by different sources led to the discovery of PSIs. METHODS: A standardized peer review process was implemented to evaluate all incident reports submitted to the ED. Findings of the peer review analysis were recorded prospectively in a quality improvement database. A retrospective analysis of the quality improvement database was performed to calculate the PSI capture rates for incident reports submitted by different source groups. RESULTS: 363 incident reports were analyzed over a period of 18 months; 211 were submitted by healthcare providers (HCPs) and 126 by non-HCPs. PSIs were identified in 108 resulting in an overall capture rate of 31%. HCP-generated reports resulted in a 44% capture rate compared to 10% for non-HCPs (p < 0.001). There was no difference in PSI capture between sub-groups of HCPs and non-HCPs. CONCLUSION: HCP-generated ED incident reports were much more likely to capture PSIs than reports submitted by non-HCPs. However, HCP reports still led to PSI discovery less than half the time. Further research is warranted to develop effective strategies to improve the utility of incident reports from both HCPs and non-HCPs.

BACKGROUND: Emergency Department (ED) care has been reported to be prone to patient safety incidents (PSIs). Improving our understanding of PSIs is essential to prevent them. A standardized, peer review process was implemented to identify and analyze ED PSIs. The primary objective of this investigation was to characterize ED PSIs identified by the peer review process. A secondary objective was to characterize PSIs that led to patient harm. In addition, we sought to provide a detailed description of the peer review process for others to consider as they conduct their own quality improvement initiatives. METHODS: An observational study was conducted in a large, urban, tertiary-care ED. Over a two-year period, all ED incident reports were investigated via a standardized, peer review process. PSIs were identified and analyzed for contributing factors including systems failures and practitioner-based errors. The classification system for factors contributing to PSIs was developed based on systems previously reported in the emergency medicine literature as well as the investigators' experience in quality improvement and peer review. All cases in which a PSI was discovered were further adjudicated to determine if patient harm resulted. RESULTS: In 24 months, 469 cases were investigated, identifying 152 PSIs. In total, 188 systems failures and 96 practitioner-based errors were found to have contributed to the PSIs. In twelve cases, patient harm was determined to have resulted from PSIs. Systems failures were identified in eleven of the twelve cases in which a PSI resulted in patient harm. CONCLUSION: Systems failures were almost twice as likely as practitioner-based errors to contribute to PSIs, and systems failures were present in the majority of cases resulting in patient harm. To effectively reduce PSIs, ED quality improvement initiatives should focus on systems failure reduction.

Medical marijuana remains a highly debated treatment regimen despite removal of state penalties against care providers prescribing the drug and patients treated with the drug in many areas of the USA. The utility of marijuana in specific medical conditions has been studied at length, but its effects on driving performance and risk of motor vehicle collision remain unclear. As with other medications that affect psychomotor function, the healthcare provider should be informed of the potential risks of driver safety prior to prescribing this psychotropic drug to give appropriate anticipatory guidance for appropriate use. The goal of this narrative review is to assess the current literature regarding marijuana as it relates to driving performance and traffic safety. With a foundation in the pharmacology of cannabinoids, we consider the limitations of testing cannabinoid and metabolite concentration. In addition, we will review studies on driving performance and epidemiological studies implicating marijuana in motor vehicle collisions. The increasing prevalence of medical marijuana laws in the USA suggests that clinicians should be aware of marijuana's influence on public safety. Patients should abstain from driving for 8 h if they achieve a subjective "high" from self-treatment with smoked marijuana and should be aware of the cumulative effects of alcohol and other psychoactive xenobiotics.

PURPOSE: This study aimed to identify factors of neurologic prognosis in severe accidental hypothermic patients with cardiac arrest. BASIC PROCEDURES: This retrospective observational study was performed in a tertiary care university hospital in Sapporo, Japan (January 1994 to December 2012). We investigated 26 patients with accidental hypothermic cardiac arrest resuscitated with extracorporeal cardiopulmonary resuscitation (ECPR). We evaluated the neurologic outcome in patients who were resuscitated with ECPR at discharge from hospital. MAIN FINDINGS: In those 26 patients, their median age was 50.5 years; and 69.2% were male. The cause of hypothermia was exposure to cold air in 46.1%, submersion in 46.1%, and avalanche in 7.8%. Ten (38.5%) of these patients survived to favorable neurological outcome at discharge. Factors associated with favorable neurological outcome were a cardiac rhythm other than asystole (P = .009), nonasphyxial hypothermia (P = .006), higher pH (P = .01), and lower serum lactate (P = .01). In subgroup analyses, the patients with hypothermic cardiac arrest due to submersion or avalanche (asphyxia group) showed no factors associated with good neurological outcome, whereas the nonasphyxia group showed a significantly lower core temperature (P = .02) and a trend towards a lower serum lactate (P = .09). PRINCIPAL CONCLUSIONS: Patients with hypothermic cardiac arrest due to nonasphyxial hypothermia have improved neurologic outcomes when treated with ECPR compared to patients with asphyxial hypothermic cardiac arrest. Further investigation is needed to develop a prediction rule for patients with nonasphyxial hypothermic cardiac arrest to determine which patients would benefit from treatment with ECPR.

Organophosphorus (OP) pesticides are a diverse class of acetylcholinesterase (AChE) inhibitors that are responsible for tremendous morbidity and mortality worldwide, killing approximately 300,000 people annually. Enzymatic hydrolysis of OPs is a potential therapy for acute poisoning. OpdA, an OP hydrolase isolated from Agrobacterium radiobacter, has been shown to decrease lethality in rodent models of OP poisoning. This study investigated the effects of OpdA on AChE activity, plasma concentrations of OP, and signs of toxicity after administration of dichlorvos to nonhuman primates. A dose of 75 mg/kg dichlorvos given orally caused apnea within 10 min with a progressive decrease in heart rate. Blood AChE activity decreased to zero within 10 min. Respirations and AChE activity did not recover. The mean dichlorvos concentration rose to a peak of 0.66 µg/ml. Treated monkeys received 1.2mg/kg OpdA iv immediately after poisoning with dichlorvos. In Opda-treated animals, heart and respiratory rates were unchanged from baseline over a 240-minute observation period. AChE activity slowly declined, but remained above 25% of baseline for the entire duration. Dichlorvos concentrations reached a mean peak of 0.19 µg/ml at 40 min after poisoning and decreased to a mean of 0.05 µg/ml at 240 min. These results show that OpdA hydrolyzes dichlorvos in an African green monkey model of lethal poisoning, delays AChE inhibition, and prevents lethality.

BACKGROUND: Regional preparedness efforts related to the stockpiling and interhospital sharing of critical antidotal medications is an important topic in the age of terrorism and weapons of mass destruction. Little attention has been paid to how well regional preparedness efforts specifically affect availability of pralidoxime (2-PAM) if it were needed to treat a mass poisoning with acetylcholinesterase inhibitors (organophosphorus pesticides or nerve agents). OBJECTIVES: The authors sought to assess whether hospitals in one region of Massachusetts (Department of Public Health Region 2, Central Massachusetts) have adequate plans for responding to a large number of patients requiring 2-PAM as might occur after the intentional release of nerve agents or organophosphorus chemicals into a civilian population or the food or water supply. METHODS: The Massachusetts DPH Region 2 contains 10 acute care hospitals including one level 1 Trauma Center that is also the only tertiary care hospital in the region. A 13-question online survey was used to assess three important components of 2-PAM availability: 1) the amount of 2-PAM available, 2) regional medication sharing activities, and 3) attitudes and awareness of resources available in the Strategic National Stockpile (SNS). RESULTS: Seven of 10 hospitals participated in the survey (response rate 70 percent). Of these seven hospitals, only 2 (28.5 percent) had any 2-PAM on hand (4 and 6 g). Despite the existence of a region-wide memorandum of understanding that includes medication sharing, only two hospitals' responses included awareness of this agreement. Two hospitals had considered the problem of inadequate 2-PAM supplies before receiving the survey. Five of 7 (71.4 percent) hospitals would consider accessing the SNS if the need for antidotes were exceeded by their own supply. CONCLUSION: Recognition of regional planning for sharing of antidotes such as 2-PAM is lacking in the surveyed region and could lead to inability to care for large number of patients affected by an intentional or accidental large-scale release of acetylcholinesterase inhibitors.

Sodium bicarbonate is central to the treatment of many poisonings. When it was placed on the FDA drug shortage list in 2012, alternative treatment strategies to specific poisonings were considered. Many hospital pharmacies, poison centers, and medical toxicologists proposed sodium acetate as an adequate alternative, despite a paucity of data to support its use in medical toxicology. The intention of this review is to educate the clinician on the use of sodium acetate and to advise them on the potential adverse events when given in excess. We conducted a literature search focused on the pharmacology of sodium acetate, its use as a buffer in pathologic acidemia and dialysis baths, and potential adverse events associated with excess sodium acetate infusion. It appears safe to replace sodium bicarbonate infusion with sodium acetate on an equimolar basis. The metabolism of acetate, however, is more complex than bicarbonate. Future prospective studies will be needed to confirm the efficacy of sodium acetate in the treatment of the poisoned patient.

BACKGROUND: Efforts to reduce door-to-balloon (DTB) times for patients presenting with an ST-elevation myocardial infarction (STEMI) are widespread. Reductions in DTB times have been shown to reduce short-term mortality and decrease inpatient length of stay (LOS) in these high-risk patients. However, there is a limited literature examining the effect that these quality improvement (QI) initiatives have on patient care costs. METHODS: A STEMI QI program (Cardiac Alert Team [CAT]) initiative was instituted in July 2006 at a single tertiary care medical center located in central Massachusetts. Information was collected on cost data and selected clinical outcomes for consecutively admitted patients with a STEMI. Differences in adjusted hospital costs were compared in three cohorts of patients hospitalized with a STEMI: one before the CAT initiative began (January 2005-June 2006) and two after (October 1, 2007-September 30, 2009, and October 1, 2009-September 30, 2011). RESULTS: Before the CAT initiative, the average direct inpatient costs related to the care of these patients was $14,634, which decreased to $13,308 (-9.1%) and $13,567 (-7.3%) in the two sequential periods of the study after the CAT initiative was well established. Mean DTB times were 91 minutes before the CAT initiative and were reduced to 55 and 61 minutes in the follow-up periods (p < .001). There was a nonsignificant reduction in LOS from 4.4 days pre-CAT to 3.6 days in both of the post-CAT periods (p = .11). CONCLUSIONS: A QI program aimed at reducing DTB times for patients with a STEMI also led to a significant reduction in inpatient care costs. The greatest reduction in costs was related to cardiac catheterization, which was not expected and was likely a result of standardization of care and identification of practice inefficiencies.
