Impact of a critical pathway on acute myocardial infarction quality indicators

The effect of acute coronary syndrome care pathways on in-hospital patients: A systematic review

BACKGROUND

Health care institutions need to construct management strategies for patients diagnosed with acute coronary syndrome (ACS) that focus on evidence-based treatments, adherence to treatment guidelines, and organized care. These help to reduce variations as well as the mortality and morbidity rates, which indicates the critical need for standardized care and adherence to evidence-based practices for patients hospitalized with ACS. The care pathways translate research and guidelines into clinical practice to close the gap between the guidelines and the clinical practices.

OBJECTIVES

This review focuses on identifying the indicators used to evaluate ACS care pathways and their effect on the care process and clinical outcomes.

METHODS

This review follows the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The systematic research was conducted using five research databases. Two groups were created by dividing the studies according to their year of publication. The first group included those studies published from 1997 to 2007 ("Group 1"), while the second included those published from 2008 to 2018 ("Group 2"). Selected studies were screened using the Effective Public Health Practice Project (EPHPP) quality assessment tool.

RESULTS

Seventeen studies were included in this review. One study was a randomized controlled trial, 14 were predesigns and postdesigns, and two were longitudinal observational designs. The Group 1 studies demonstrated that ACS care pathways had a positive effect on reducing the length of the hospital stay and the door-to-balloon times. Similar effects were observed for the Group 2 studies.

CONCLUSION

Implementing ACS care pathway helps to organize care processes and decrease treatment delays as well as improve the patient outcomes without adverse consequences for patients or additional resources and costs. While the current level of evidence is inadequate to warrant a formal recommendation, there is a need for more studies with an emphasis on well-designed randomization to measure patient outcomes.

Sustainability of clinical pathway guided care in cardiac surgery ICU patients; 9-years experience in over 7500 patients

OBJECTIVE

To determine trends over time regarding inclusion of post-operative cardiac surgery intensive care unit (ICU) patients in a clinical pathway (CP), and the association with clinical outcome.

DESIGN

Retrospective cohort study.

SETTING

ICU of an academic hospital.

PARTICIPANTS

All cardiac surgery patients operated between 2007 and 2015.

MEASURES AND RESULTS

A total of 7553 patients were operated. Three patient groups were identified: patients treated according to CP (n = 6567), patients excluded from the CP within the first 48 h (n = 633) and patients never included in CP (n = 353). Patients treated according to CP increased significantly over time from 74% to 95% and the median Log EuroSCORE (predicted mortality score) in this group increased significantly over time (P = 0.016). In-hospital length of stay (LOS) decreased in all groups, but significantly in CP group (P < 0.001). Overall, the in-hospital, and 1-year mortality decreased from 1.5 to 1.1% and 3.7 to 2.9%, respectively (both P < 0.05). Patients with a Log EuroSCORE >10 were more likely excluded from CP (P < 0.001), but, if included in CP, these patients had a significantly shorter Intensive Care stay and in-hospital stay compared to excluded patients with a Log EuroSCORE >10 (both P < 0.001).

CONCLUSIONS

The use of a CP for all post-operative cardiac surgery patients in the ICU is sustainable. While more complex patients were treated according to the CP, clinical outcome improved in the CP group.

Patient healthcare trajectory. An essential monitoring tool: a systematic review

BACKGROUND

Patient healthcare trajectory is a recent emergent topic in the literature, encompassing broad concepts. However, the rationale for studying patients' trajectories, and how this trajectory concept is defined remains a public health challenge. Our research was focused on patients' trajectories based on disease management and care, while also considering medico-economic aspects of the associated management. We illustrated this concept with an example: a myocardial infarction (MI) occurring in a patient's hospital trajectory of care. The patient follow-up was traced via the prospective payment system. We applied a semi-automatic text mining process to conduct a comprehensive review of patient healthcare trajectory studies. This review investigated how the concept of trajectory is defined, studied and what it achieves.

METHODS

We performed a PubMed search to identify reports that had been published in peer-reviewed journals between January 1, 2000 and October 31, 2015. Fourteen search questions were formulated to guide our review. A semi-automatic text mining process based on a semantic approach was performed to conduct a comprehensive review of patient healthcare trajectory studies. Text mining techniques were used to explore the corpus in a semantic perspective in order to answer non-a priori questions. Complementary review methods on a selected subset were used to answer a priori questions.

RESULTS

Among the 33,514 publications initially selected for analysis, only 70 relevant articles were semi-automatically extracted and thoroughly analysed. Oncology is particularly prevalent due to its already well-established processes of care. For the trajectory thema, 80% of articles were distributed in 11 clusters. These clusters contain distinct semantic information, for example health outcomes (29%), care process (26%) and administrative and financial aspects (16%).

CONCLUSION

This literature review highlights the recent interest in the trajectory concept. The approach is also gradually being used to monitor trajectories of care for chronic diseases such as diabetes, organ failure or coronary artery and MI trajectory of care, to improve care and reduce costs. Patient trajectory is undoubtedly an essential approach to be further explored in order to improve healthcare monitoring.

Quality toolbox: clinical pathways can improve core measure scores

Clinical pathways (CPs) are decision-making tools designed to improve the quality of patient care processes and reduce costs. We conducted a retrospective analysis to determine whether multidisciplinary CPs had improved core measure scores. Comparative data to document secular trends were obtained from 45 Maryland hospitals. There were 6013 discharges with community-acquired pneumonia (CAP), congestive heart failure (CHF), or acute myocardial infarction (AMI) for the 3-year data collection period ending in 9/30/05. The 72.5% of cases in which CPs were employed to manage CAP, CHF, or AMI were significantly more likely to meet the Appropriate Care Measure (ACM) standards than the 26% that did not (81% vs. 67.8%, p < .001). Scores for all 10 ACM components for CP-managed patients were better than Maryland state averages. Improvements were stable over a 3-year period of time.

A review of interventions and system changes to improve time to reperfusion for ST-segment elevation myocardial infarction

OBJECTIVE

Identify and describe interventions to reduce time to reperfusion for patients with ST-segment elevation myocardial infarction (STEMI).

DATA SOURCE

Key word searches of five research databases: MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, Web of Science, and Cochrane Clinical Trials Registry.

INTERVENTIONS

We included controlled and uncontrolled studies of interventions to reduce time to reperfusion. One researcher reviewed abstracts and 2 reviewed full text articles. Articles were subsequently abstracted into structured data tables, which included study design, setting, intervention, and outcome variables. We inductively developed intervention categories from the articles. A second researcher reviewed data abstraction for accuracy.

MEASUREMENTS AND MAIN RESULTS

We identified 666 articles, 42 of which met inclusion criteria. We identified 11 intervention categories and classified them as either process specific (e.g., emergency department administration of thrombolytic therapy, activation of the catheterization laboratory by emergency department personnel) or system level (e.g., continuous quality improvement, critical pathways). A majority of studies (59%) were single-site pre/post design, and nearly half (47%) had sample sizes less than 100 patients. Thirty-two studies (76%) reported significantly lower door to reperfusion times associated with an intervention, 12 (29%) of which met or exceeded guideline recommended times. Relative decreases in times to reperfusion ranged from 15 to 82% for door to needle and 13-64% for door to balloon.

CONCLUSIONS

We identified an array of process and system-based quality improvement interventions associated with significant improvements in door to reperfusion time. However, weak study designs and inadequate information about implementation limit the usefulness of this literature.

Continuity of cardiac care: cardiac rehabilitation participation and other correlates

BACKGROUND

Continuity of care refers to the ongoing management of a patient's care over time and across practitioners, and the patient's experience of this care as coherent and consistent with their medical needs and context. Continuity of cardiac care is integral to secondary prevention and improved health outcomes.

DESIGN

This study examined patient perceptions of continuity, and how they relate to cardiac rehabilitation participation and other correlates.

METHODS

Consecutive acute coronary syndrome patients at 3 hospitals were approached, and 661 consented to complete a survey (504 men, 157 women; 75% response rate). Nine months later, 506 participants completed a survey including the Heart Continuity of Care Questionnaire, open-ended continuity perceptions, and self-reported cardiac rehabilitation participation (yes/no).

RESULTS

The mean continuity perceptions were highly positive, and were equivalent to those found in another Canadian province, although open-ended responses revealed discontinuity with regard to outpatient visits and pharmacotherapy prescriptions. In a multivariate model (p=.003), the correlates of greater perceptions of continuity of cardiac care 9 months post-discharge were cardiac rehabilitation participation (p<.05), greater tangible support (p<.05), and less serious perceptions of illness consequences (p<.001) at the time of the acute coronary syndrome, after controlling for demographic and clinical factors.

CONCLUSION

Given the benefits of continuity of care, it is important to promote cardiac rehabilitation participation, a significant correlate of continuity, and to solicit various supports throughout the process of cardiac recovery.

Hospital protocols and evidence-based therapies: the importance of integrating aldosterone blockade into the management of patients with post-acute myocardial infarction heart failure

Left ventricular systolic dysfunction (LVSD) and clinical heart failure are common complications of acute myocardial infarction (AMI) and result in substantially increased mortality and morbidity. Evidence-based cardiovascular protective therapies, including angiotensin-converting enzyme inhibitors, beta blockers, antiplatelet agents, and lipid-lowering medications, improve outcomes for these patients. However, this population is significantly undertreated with these guideline-recommended agents. Critical pathways have been demonstrated to improve the quality and consistency of treatment; as such, the new American College of Cardiology/American Heart Association (ACC/AHA) guidelines for the management of patients with ST-elevation myocardial infarction (STEMI) recommend that critical pathways be implemented for the management of these patients. The recent Eplerenone Post-acute Myocardial Infarction Heart Failure Efficacy and Survival Study (EPHESUS) demonstrates that eplerenone, a selective aldosterone blocker, has incremental benefit in decreasing mortality and morbidity when used with standard care therapies in patients post AMI with heart failure and LVSD. The clinical trial evidence coupled with the national guidelines provides a strong rationale for routine incorporation of aldosterone blockade into new or already established critical pathways for AMI complicated by LVSD and heart failure.
