Critical pathways in cardiology
-
Critical pathways (CP) are clinical management plans that provide the sequence and timing of actions of medical staff. The main goal of a CP is to provide optimal patient care and to improve time-effectiveness. Current guidelines for the treatment of ST-segment elevation myocardial infarction (STEMI) recommend a door-to-balloon time of <90 minutes for patients undergoing primary percutaneous coronary intervention (PCI). The aim of this study was to identify the effects of CP on the management of patients with STEMI in an emergency department. ⋯ The effects of CP implementation on the medication use outcomes in patients with acute myocardial infarction were increased between the pre- and post-CP patients groups. The median door-to-balloon time declined significantly from 85 to 64 minutes after CP implementation (P = 0.001), and the primary PCI rate within 90 minutes was significantly increased (57% vs. 79%, P = 0.01). However, the symptom to door time was not changed between the pre- and post-CP groups (150 minutes vs. 149 minutes; P = 0.841). Although the total ischemic time was decreased after CP implementation, it was not statistically insignificant (352.5 minutes vs. 281 minutes; P = 0.397). Moreover, the 30-day and 1-year total mortality rates of the 2 groups did not change (12.0% vs. 12.0%, P > 0.999; 13.0% vs. 17.3%, P = 0.425, respectively). However, the 1-year mortality rates of 2 groups based on a total ischemic time of 240 minutes, which was median value, decreased significantly from 19.0% to 9.0%. (P = 0. 018) CONCLUSION:: Implementation of a CP resulted in greater use of recommended medications and reductions in the median door-to-balloon time. However, it did not reduce the symptom onset-to-door time, total ischemic time, or the 30-day and 1-year mortality rates. Therefore, additional strategies are needed to reduce mortality in patients with acute myocardial infarction undergoing primary PCI.

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. ⋯ 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.

Successful collaborative model for STEMI care between a STEMI-referral and a STEMI receiving center.
Patients with ST-segment elevation myocardial infarction (STEMI) greatly benefit from a rapid door-to-balloon (D2B) time. For hospitals without a catheterization laboratory, it is imperative to establish partnerships with a STEMI receiving center (SRC). STEMI systems of care have been established to facilitate these relationships to improve rapid reperfusion. We describe the experience and benefits of such a relationship. ⋯ Streamlining STEMI patient care to reduce D2B is a major priority. We have demonstrated that establishing a transfer program between a STEMI-Referral Hospital (SRH) and SRC can markedly improve time to reperfusion. This approach has resulted in D12B that match or exceeds the D2B for nontransfer patients at most STEMI-receiving hospitals.

Physicians' gender may impact test utilization in the diagnosis of acute cardiovascular disease. We sought to determine if physician gender affected stress test utilization by patient gender in a low-risk chest pain observation unit. ⋯ Male physicians appear less likely to utilize stress testing in female patients even after controlling for objective clinical variables, including TIMI score. Although adverse outcomes are uncommon in this patient cohort, further investigation into provider-specific practice patterns based on patient gender is necessary.

Hypertension and atrial fibrillation (AFib) frequently coexist in clinical practice. However, it is unclear whether this association per se or in combination with coronary artery disease (CAD) is a predictor of adverse outcomes. ⋯ In patients with hypertension, AFib, and e-TnI, tailored-care inclusive of echocardiography and stress testing succeeded in recognizing and treating CAD avoiding adverse events without increase in admissions.
