[PMID: 38828238 PMCID: PMC11139363 DOI: 10.18295/squmj.12.2023.089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 09/28/2023] [Accepted: 11/14/2023] [Indexed: 06/05/2024] Open
Abstract
Objectives This study aimed to estimate the door-to-balloon (DTB) time and determine the organisational-level factors that influence delayed DTB times among patients with ST-elevation myocardial infarction in Oman. Methods A cross-sectional retrospective study was conducted on all patients who presented to the emergency department at Sultan Qaboos University Hospital and Royal Hospital, Muscat, Oman, and underwent primary percutaneous coronary interventions during 2018-2019. Results The sample included 426 patients and the median DTB time was 142 minutes. The result of the bivariate logistic regression showed that patients who presented to the emergency department with atypical symptoms were 3 times more likely to have a delayed DTB time, when compared to patients who presented with typical symptoms (odds ratio [OR] = 3.003, 95% confidence interval [CI]: 1.409-6.400; P = 0.004). In addition, patients who presented during off-hours were 2 times more likely to have a delayed DTB time, when compared to patients who presented during regular working hours (OR = 2.291, 95% CI: 1.284-4.087; P = 0.005). Conclusion To meet the DTB time recommendation, it is important to ensure adequate staffing during both regular and irregular working hours. Results from this study can be used as a baseline for future studies and inform strategies for improving the quality of care.

Abstract
Background We evaluated whether a comprehensive ST‐segment–elevation myocardial infarction protocol (CSP) focusing on guideline‐directed medical therapy, transradial percutaneous coronary intervention, and rapid door‐to‐balloon time improves process and outcome metrics in patients with moderate or high socioeconomic deprivation. Methods and Results A total of 1761 patients with ST‐segment–elevation myocardial infarction treated with percutaneous coronary intervention at a single hospital before (January 1, 2011–July 14, 2014) and after (July 15, 2014– July 15, 2019) CSP implementation were included in an observational cohort study. Neighborhood deprivation was assessed by the Area Deprivation Index and was categorized as low (≤50th percentile; 29.0%), moderate (51st –90th percentile; 40.8%), and high (>90th percentile; 30.2%). The primary process outcome was door‐to‐balloon time. Achievement of guideline‐recommend door‐to‐balloon time goals improved in all deprivation groups after CSP implementation (low, 67.8% before CSP versus 88.5% after CSP; moderate, 50.7% before CSP versus 77.6% after CSP; high, 65.5% before CSP versus 85.6% after CSP; all P<0.001). Median door‐to‐balloon time among emergency department/in‐hospital patients was significantly noninferior in higher versus lower deprivation groups after CSP (noninferiority limit=5 minutes; Pnoninferiority high versus moderate = 0.002, high versus low <0.001, moderate versus low = 0.02). In‐hospital mortality, the primary clinical outcome, was significantly lower after CSP in patients with moderate/high deprivation in unadjusted (before CSP 7.0% versus after CSP 3.1%; odds ratio [OR], 0.42 [95% CI, 0.25–0.72]; P=0.002) and risk‐adjusted (OR, 0.42 [95% CI, 0.23–0.77]; P=0.005) models. Conclusions A CSP was associated with improved ST‐segment–elevation myocardial infarction care across all deprivation groups and reduced mortality in those from moderate or high deprivation neighborhoods. Standardized initiatives to reduce care variability may mitigate social determinants of health in time‐sensitive conditions such as ST‐segment–elevation myocardial infarction.

Fang HY, Lee WC. Warning system improve the clinical outcomes in transfer patients with ST-segment elevation myocardial infarction. Medicine (Baltimore) 2021; 100:e26558. [PMID: 34190194 PMCID: PMC8257831 DOI: 10.1097/md.0000000000026558] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2021] [Accepted: 06/12/2021] [Indexed: 01/04/2023] Open
Abstract
A warning system included directly faxing electrocardiography information to the mobile phone immediately after an ST-segment elevation myocardial infarction (STEMI) diagnosis was made at a non-percutaneous coronary intervention (PCI) capable hospital. This study aimed to explore the outcomes after using a warning system in transfer STEMI patients.From October 2013 to December 2016, 667 patients experienced a STEMI event and received primary PCI at our institution. 274 patients who were divided into transfer group were transferred from non-PCI capable hospitals and connected to a first-line cardiovascular doctor by the warning system. Other 393 patients were divided into the non-transfer group.The transfer group still had a longer pain-to-reperfusion time and presented higher troponin-I level when compared with non-transfer group. There was no significant difference in the use of drug-eluting stent and procedural devices between non-transfer and transfer groups. The prevalence of different anti-platelet agents loading did not differ between non-transfer and transfer groups. Non-significant trend about higher prevalence of statin use was noted in transfer group (78.9% vs 86.1%, P = .058). The transfer group presented similar clinical short-term results regarding both cardiovascular and all-cause mortality when comparing with non-transfer group. The transfer group provided non-significant trend about lower one-year cardiovascular mortality (10.7% vs 6.2%, P = .052) and lower all-cause mortality (12.2% vs 6.9%, P = .026) when compared with non-transfer group. There was a significant difference in the Kaplan-Meier curve of 1-year cardiovascular mortality between the transfer group and the non-transfer group (P = .049).After using the warning system, the inter-facility transfer group had comparable outcomes even though a longer pain-to-reperfusion time and a higher peak troponin-I level when comparing with non-transfer group.

The impact of door-to-electrocardiogram time on door-to-balloon time after achieving the guideline-recommended target rate. PLoS One 2019; 14:e0222019. [PMID: 31498823 PMCID: PMC6733447 DOI: 10.1371/journal.pone.0222019] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2019] [Accepted: 08/20/2019] [Indexed: 01/03/2023] Open
Abstract
Background Little is known about the components and contributing factors of door-to-balloon time after implementation of Door-to-Balloon Alliance quality-improving (QI) strategies, including the impact of door-to-ECG time on door-to-balloon time. Objective We investigated whether modification of emergency department (ED) triage processes could improve door-to-ECG and door-to-balloon times after implementation of QI strategies. Methods This was a retrospective before-and-after study of a prospectively collected database. From June 2014 to October 2014, interventions were implemented in our ED, including a protocol-driven ECG initiation and moving an ECG station and technician to the triage area. The primary outcome was the percentage of patients with ST-elevation myocardial infarction (STEMI) who received ECG within 10 min of arrival; the secondary outcome was the percentage of patients with door-to-balloon times of <90 min from arrival. Patients from the year pre- and post-QI initiative were defined as the control and intervention groups, respectively. Results Enrollment comprised 214 patients with STEMI: 109 before the intervention and 105 after the intervention. We analyzed the components of the door-to-balloon process and found the door-to-ECG process was the most critical interval of delay (20.8%). Unrecognized symptoms were the most common cause of delay in the door-to-ECG process resulting in a significant impact on the door-to-balloon time. The intervention group had a higher percentage of patients with door-to-ECG times <10 min than did the control group (93.3% vs. 79.8%, p = 0.005), with a corresponding improvement in door-to-balloon times <90 min (91.1% vs. 76.2%, p = 0.007). In subgroup analysis, the intervention benefits occurred only in non-transferred or walk-in patients. After adjustment for possible co-variates, the QI interventions remained a significant contributing factor for achieving the door-to-ECG and door-to-balloon targets. Conclusions The modification of ED triage processes through implementation of QI strategies are effective in achieving better door-to-ECG times and thus, achieving door-to-balloon times <90 min. In patients presenting with ambiguous symptoms, improved door-to ECG target achievement rates, through a protocol-driven and multidisciplinary approach allows for earlier identification of STEMI.

Abstract
Background: Various systems have employed with the objective to reduce the time from emergency medical services contact to balloon inflammation for ST-elevation myocardial infraction (STEMI) patients. The WCACG message system was used to an alternative communication platform to improve confirmation of the diagnosis and movement to treatment, resulted in shorten the door-to-balloon (D-to-B) time for STEMI patients. Methods: We collected 366 STEMI patients admitted at the Sixth Affiliated Hospital of Guangzhou Medical University, Qingyuan People’s Hospital, Department of Cardiology, during the period from June 2013 to October 2015. The patients were divided into two groups one underwent the current GC processes and the other group was handled using WCACG system. We compared between two groups with several indicators including D-to-B time, duration of hospitalization, associated costs, and incidence of adverse cardiovascular events. Results: The results show that the new method with WCACG system significantly reduced the average D-to-B time (from 100.42 ± 25.14 mins to 79.81 ± 20.51 mins, P < 0.05) compared to the GC processes, and also reduced the duration, costs and undesirable cardiac incidence during hospitalization. Conclusions: The modified WCACG process is an applicable system to save pieces of time and efficiently integrate the opinions of experts in emergency.

Abstract
BACKGROUND Driving time to a percutaneous coronary intervention (PCI)-capable hospital is important in timely treatment of acute myocardial infarction (AMI). Our objective was to determine whether driving time from one's residence to a PCI-capable hospital contributes to AMI deaths. We conducted a cross-sectional study of age- and sex-adjusted mortality in census block groups to evaluate this question. METHODS AND RESULTS We studied all (14 027) AMI deaths that occurred during 2008-2012 in Arkansas to assess the relationship between driving time from the population center of a block group (neighborhood) to the nearest PCI-capable hospital. We estimated standardized mortality ratios in block groups that were adjusted for education (population over 25 years of age who did not graduate from high school), poverty (population living below federal poverty level), population density (population per square mile), mobility (population residing at the same address as 1 year ago), black (population that is black), rurality (rural households), geodesic distance, and driving time. The median geodesic distance and driving time were 12.8 miles (interquartile range 3.6-30.1) and 28.3 minutes (interquartile range 9.6-58.7), respectively. Risks in neighborhoods with long driving times (90th percentile) were 26% greater than risks in neighborhoods with short driving times (10th percentile), even after adjusting for education, poverty, population density, rurality, and black race (P<0.0001). CONCLUSIONS AMI mortality increases with increasing driving time to the nearest PCI-capable hospital. Improving the healthcare system by reducing time to arrive at a PCI-capable hospital could reduce AMI deaths.

Abstract
OBJECTIVES This study's aim was to describe a hospital-wide system to deliver rapid door-to-balloon time across the entire spectrum of emergency percutaneous intervention. BACKGROUND Many patients needing emergency PCI are excluded from door-to-balloon public reporting metric; these groups do not achieve door-to-balloon times ≤90 min and have increased mortality rates. METHODS We prospectively implemented a protocol for patients with STEMI or other emergency indication for catheterization mandating (1) emergency department physician or cardiologist activation of the catheterization lab and (2) immediate patient transfer to an immediately available catheterization lab by an in-house nursing transfer team. RESULTS From September 1, 2005 to December 31, 2008, 526 consecutive patients underwent emergency PCI. Median door-to-balloon time was 68 min with 85.7% ≤90 min overall. Important subgroups included primary emergency department (62.5 min), cardiorespiratory arrest (71 min), cardiogenic shock (68 min), need for temporary pacemaker or balloon pump (67 min), initial ECG without ST-elevation (66.5 min), transfer from another ED (84 min), in-hospital (70 min), and activation indications other than STEMI (68 min). Patients presenting to primary ED and in transfer were compared to historical controls. Treatment ≤90 min increased (28%-85%, P < 0.0001). Mean infarct size decreased, as did hospital length-of-stay and admission total hospital costs. Acute myocardial infarction all-cause 30-day unadjusted mortality and risk-standardized mortality ratios were substantially lower than national averages. CONCLUSION A hospital-wide systems approach applied across the entire spectrum of emergency PCI leads to rapid door-to-balloon time, reduced infarct size and hospitals costs, and low myocardial infarction 30-day all-cause mortality. © 2015 Wiley Periodicals, Inc.

Abstract
INTRODUCTION Reducing door-to-balloon (DTB) time in ST-segment elevation myocardial infarction improves outcomes. Several hospital factors can delay DTB times and lead to increased morbidity and mortality. The effects of hospital design and an interventional platform (IP) on patient care, particularly on the DTB time, are unknown. METHODS We performed a retrospective analysis of consecutive patients presenting to the emergency department of a medical center from September 2010 to February 2014 who met criteria for a ST-segment elevation myocardial infarction and underwent primary percutaneous coronary intervention. Patients were divided into 2 groups based on whether they presented before or after the opening of the IP in our new hospital on January 6, 2012. Total DTB time and separate systematic intervals were tabulated. RESULTS Fifty-two patients met our inclusion criteria, 21 pre-IP and 31 post-IP. Both groups had overall similar baseline characteristics. The mean DTB time significantly improved by 11.7 minutes after the opening of the IP (P = 0.016), and all cases had a DTB time 90 minutes or less as compared with 90.4% prior. Eighty-nine percent of the overall improvement in DTB happened before the patient reached the catheterization table. Important factors were the new emergency department (ED) design that facilitates rapid patient triage and the direct connection between the ED and cath lab. CONCLUSIONS This study showed that the new hospital design had significant effects on immediate patient care by improving the DTB time at our institution. Further study regarding the long-term impact of hospital designs on patient care is needed.

Abstract
ST-segment elevation myocardial infarction (STEMI) systems of care have been associated with significant improvement in use and timeliness of reperfusion. Consequently, national guidelines recommend that each community should develop a regional STEMI care system. However, significant barriers continue to impede widespread establishment of regional STEMI care systems in the United States. We designed the Regional Systems of Care Demonstration Project: Mission: Lifeline STEMI Systems Accelerator, a national educational outcome research study in collaboration with the American Heart Association, to comprehensively accelerate the implementation of STEMI care systems in 17 major metropolitan regions encompassing >1,500 emergency medical service agencies and 450 hospitals across the United States. The goals of the program are to identify regional gaps, barriers, and inefficiencies in STEMI care and to devise strategies to implement proven recommendations to enhance the quality and consistency of care. The study interventions, facilitated by national faculty with expertise in regional STEMI system organization in partnership with American Heart Association representatives, draw upon specific resources with proven past effectiveness in augmenting regional organization. These include bringing together leading regional health care providers and institutions to establish common commitment to STEMI care improvement, developing consensus-based standardized protocols in accordance with national professional guidelines to address local needs, and collecting and regularly reviewing regional data to identify areas for improvement. Interventions focus on each component of the reperfusion process: the emergency medical service, the emergency department, the catheterization laboratory, and inter-hospital transfer. The impact of regionalization of STEMI care on clinical outcomes will be evaluated.

Abstract
BACKGROUND An adequate door-to-balloon time (<120 minutes) is the necessary condition for the efficacy of primary angioplasty in infarction to translate into effectiveness. OBJECTIVE To describe the effectiveness of a quality of care protocol in reducing the door-to-balloon time. METHODS Between May 2010 and August 2012, all individuals undergoing primary angioplasty in our hospital were analyzed. The door time was electronically recorded at the moment the patient took a number to be evaluated in the emergency room, which occurred prior to filling the check-in forms and to the triage. The balloon time was defined as the beginning of artery opening (introduction of the first device). The first 5 months of monitoring corresponded to the period of pre-implementation of the protocol. The protocol comprised the definition of a flowchart of actions from patient arrival at the hospital, the team's awareness raising in relation to the prioritization of time, and provision of a periodic feedback on the results and possible inadequacies. RESULTS A total of 50 individuals were assessed. They were divided into five groups of 10 sequential patients (one group pre- and four groups post-protocol). The door-to-balloon time regarding the 10 cases recorded before protocol implementation was 200 ± 77 minutes. After protocol implementation, there was a progressive reduction of the door-to-balloon time to 142±78 minutes in the first 10 patients, then to 150±50 minutes, 131±37 minutes and, finally, 116±29 minutes in the three sequential groups of 10 patients, respectively. Linear regression between sequential patients and the door-to-balloon time (r = - 0.41) showed a regression coefficient of - 1.74 minutes. CONCLUSION The protocol implementation proved effective in the reduction of the door-to-balloon time.

Abstract
OBJECTIVES To study the reperfusion strategies currently being used in the treatment of ST-elevation myocardial infarction (STEMI) at an academic medical center in a developing country and to analyze the door-to-balloon time (DBT) in those patients undergoing primary percutaneous coronary intervention (PCI). METHODS The study included all patients presenting with STEMI to the emergency department at the American University of Beirut Medical Center between July 2008 and February 2010. Data were collected prospectively from the patients' medical records. RESULTS The study population consisted of 100 consecutive patients. Compared with an earlier study from American University of Beirut Medical Center done in 2002-2005, there was a significant increase in the utilization of primary PCI for reperfusion (81% vs. 2.5%; P < 0.001). However, the median DBT was 110 minutes, with only 30% of patients achieving a DBT ≤90 minutes. The predictors of delayed DBT (>90 minutes) were culprit lesions in the circumflex artery (P = 0.007) and delayed time from electrocardiogram to arrival in the catheterization laboratory (P < 0.001). CONCLUSIONS There was a significant increase in the utilization of primary PCI for reperfusion of STEMI in this academic medical center in a developing country. However, achieving a target DBT ≤90 minutes was suboptimal. Future studies are needed to analyze the logistic factors associated with delayed reperfusion to institute policies and systems that can enhance the efficacy of primary PCI as a reperfusion modality in these countries.

Abstract
Out-of-hospital cardiac arrest is common and is associated with high mortality. The majority of in-hospital deaths from resuscitated victims of cardiac arrest are due to neurologic injury. Therapeutic hypothermia (TH) is now recommended for the management of comatose survivors of cardiac arrest. The rapid triage and standardized treatment of cardiac arrest patients can be challenging, and implementation of a TH program requires a multidisciplinary team approach. In 2010, we revised our institution's TH protocol, creating a "CODE ICE" pathway to improve the timely and coordinated care of cardiac arrest patients. As part of CODE ICE, we implemented comprehensive care pathways including measures such as a burst paging system and computerized physician support tools. "STEMI on ICE" integrates TH with our regional ST-elevation myocardial infarction network. Retrospective data were collected on 150 consecutive comatose cardiac arrest victims treated with TH (n = 82 pre-CODE ICE and n = 68 post-CODE ICE) from 2007 to 2011. After implementation of CODE ICE, the mean time to initiation of TH decreased from 306 ± 165 minutes to 196 ± 144 minutes (P < 0.001), and the time to target temperature decreased from 532 ± 214 minutes to 392 ± 215 minutes (P < 0.001). There was no significant change in survival or neurologic outcome at hospital discharge. Through the implementation of CODE ICE, we were able to reduce the time to initiation of TH and time to reach target temperature. Additional studies are needed to determine the effect of CODE ICE and similar pathways on clinical outcomes after cardiac arrest.

Abstract
Background—
Little is known about the components of door-to-balloon time among patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention. We assessed the role of time from hospital arrival to ST-segment elevation myocardial infarction diagnosis (door-to-activation time) on door-to-balloon time in contemporary practice and evaluated factors that influence door-to-activation times.
Methods and Results—
Registry data on 347 consecutive patients diagnosed with a ST-segment elevation myocardial infarction in the emergency department over 30 months at 2 urban primary percutaneous coronary intervention centers were analyzed. The primary study end point was the time from hospital arrival to catheterization laboratory activation by the emergency department physician, and we assessed factors associated with this period. Door-to-balloon time and its other components were secondary study end points. The median door-to-activation time was 19 minutes (interquartile range, 9–54). Variation in door-to-activation times explained 93% of the variation in door-to-balloon times and demonstrated the strongest correlation with door-to-balloon times (
r
=0.97). Achieving a door-to-activation time of ≤20 minutes resulted in an 89% chance of achieving a door-to-balloon time of ≤90 minutes compared with only 28% for patients with a door-to-activation time >20 minutes. Factors significantly associated with door-to-activation time include the following: prehospital ECG use (61% shorter, 95% confidence interval, −50 to −72%;
P
<0.001) and computed tomography scan use in the emergency department (245% longer, 95% confidence interval, +50 to +399%;
P
=0.001).
Conclusions—
The interval from hospital arrival to ST-segment elevation myocardial infarction diagnosis and catheterization laboratory activation (door-to-activation time) is a strong driver of overall door-to-balloon times. Achieving a door-to-activation time ≤20 minutes was key to achieving a door-to-balloon time ≤90 minutes. Delays in door-to-activation time are not associated with delays in other aspects of the primary percutaneous coronary intervention process.

Abstract
BACKGROUND Primary percutaneous coronary intervention (PCI) in patients with ST-elevation myocardial infarction (STEMI) significantly reduces mortality and morbidity, particularly when door-to-balloon (D2B) time is < 90 min. We sought to minimize preventable delays by instituting an on-site cardiology team-based approach in the emergency department (ED). METHODS The on-site group comprised 146 consecutive patients with STEMI undergoing primary PCI after implementation of the on-site strategy. This new patient care model was compared with the conventional care administered before instituting the on-site cardiology team-based strategy in ED, which included 90 patients (interim group) receiving primary PCI at a catheterization room in the same building as the ED, and 147 patients (pre-on-site group) undergoing primary PCI at a catheterization room two blocks away from the ED. RESULTS Median D2B time decreased from 107 min in the pre-on-site group to 72 min in the interim group, and to 47 min in the on-site group, respectively (p < 0.001). The percentage of D2B times < 90 min increased from 34% to 78% and 96%, respectively among the three groups (p < 0.001). Hospitalization costs were significantly reduced in the on-site and interim vs. pre-on-site groups ($5944, $5999, and $6581, respectively; p = 0.008). In-hospital mortality did not differ significantly among the three groups (4.8%, 2.2%, and 6.1%, respectively; p = 0.387). CONCLUSIONS Institution of an on-site cardiology team-based approach in the ED significantly reduces D2B time in STEMI patients eligible for primary PCI.

Data feedback reduces door-to-balloon time in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention. Heart Vessels 2010; 26:25-30.

Abstract
Current guidelines recommend a goal of door-to-balloon (D2B) time < 90 min for patients undergoing primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI). We aim to prospectively determine the effect of data feedback on D2B time and its seven individual components in primary PCI. From December 7, 2007, to June 2, 2009, 116 consecutive patients with STEMI who received PCI within 12 h of symptom onset were enrolled, including 56 patients before and 60 patients after the implementation of data feedback on July 28, 2008. The proportion of patients treated within 90 min increased from 26.8 to 55.0% (p = 0.002). On multivariable analyses, data feedback (OR 5.3, p = 0.003), known coronary artery disease (OR 5.6, p = 0.043), regular hours presentation (OR 3.3, p = 0.048), and arrival by transfer (OR 14.0, p = 0.003) were independent predictors of a D2B time less than 90 min. Median D2B time decreased from 112 min before data feedback to 87 min after data feedback (p < 0.001). The most significant decrease occurred in median door-to-ECG (11 vs. 3 min, p < 0.001), consult-to-cardiologist (5 vs. 3 min, p < 0.001), and puncture-to-balloon (21 vs. 17 min, p = 0.004) time. Data feedback to the emergency department and catheterization laboratory staff decreases D2B time in primary PCI. This simple approach may be the best first step to decrease D2B time in hospitals that are still striving to achieve the goal of D2B time < 90 min.
