Diagnosis and treatment of atrial fibrillation in the acute care setting

High sensitivity C reactive protein levels and atrial fibrillation recurrence after catheter ablation for atrial fibrillation: A systematic review and meta-analysis

Background

Atrial fibrillation (AF) recurrence after AF ablation is not uncommon. High sensitivity C reactive protein (hs-CRP) is a widely used inflammatory marker with a potential property to predict AF recurrence. We conducted a systematic review and a meta-analysis to find an association between hs-CRP levels and AF recurrence after ablation.

Methods

We searched PubMed, Embase, and Wiley-Cochrane Library from inception to January 2022 for studies that reported hs-CRP levels in patients who underwent AF ablation. Weighted mean difference (WMD) was used to evaluate the difference between hs-CRP levels in post-ablation AF recurrent and non-recurrent group. Also, the difference between hs-CRP levels in pre- and post-ablation was determined.

Results

We identified 10 studies, and a total of 789 patients were included (299 recurrent vs. 490 non-recurrent patients). The mean age was 57.7 years (76.4% male). There was no difference in baseline hs-CRP levels between AF recurrent and non-recurrent group (WMD = 0.05, 95% CI = -0.04 to 0.15, p = 0.045). However, higher hs-CRP levels post-ablation were found in AF recurrent group (WMD = 0.09, 95% CI = 0.03-0.15, p < 0.001).

Conclusion

There is no significant difference in baseline hs-CRP levels between AF recurrent and non-recurrent patients after AF ablation. However, higher post-ablation hs-CRP level was found in AF recurrent group. High Sensitivity C reactive protein may play a role as a predictor of AF recurrence.

Pharmacist involvement on a rapid response team

PURPOSE

The effect of a pharmacist on a rapid response team (RRT) was investigated.

METHODS

This study evaluated 234 patients before and 157 patients after pharmacist involvement on an RRT. The primary outcome was time to medication administration, with a goal turnaround time of less than 30 minutes. Secondary outcomes included most frequently used medications, readmissions to the intensive care unit (ICU) within 48 hours, number of rapid responses that resulted in ICU admission, length of hospital stay, and survival to hospital discharge. Additionally, pharmacist interventions were tracked in the postinterventional group.

RESULTS

The preinterventional group screened 326 rapid response events, of which 234 were included for analysis; during the postinterventional phase, 256 rapid response events were evaluated, of which 157 were included. The primary outcome, median time to medication administration from central pharmacy, was lower in the postinterventional group compared with the preinterventional group (32.0 minutes versus 64.5 minutes, p = 0.004). ICU admission rates following rapid response were not significantly different between the two groups. Additionally, there were no significant differences between rates of medical emergency and survival to hospital discharge. The most common medications administered were metoprolol and naloxone. Pharmacists provided documentation for 90 of 157 (57%) patient cases. In the 90 cases with documentation, 18 (20% of patients) had documented pharmacist interventions, including dosing assistance for 8 cases (44% of interventions).

CONCLUSION

The addition of a pharmacist to an RRT reduced time to medication administration, helped improve medication accessibility, and helped optimize medication selection and dosing.

Evaluation of an evidence-based practice implementation: prophylactic amiodarone following coronary artery revascularization

Postoperative atrial fibrillation is the most frequent dysrhythmia following coronary artery bypass grafting and is associated with complications, additional therapy, and longer hospital stays. Prophylactic amiodarone protocols have been validated as safe and beneficial in the prevention of atrial fibrillation following cardiac surgery. This study evaluates the use of our current treatment protocol, given prophylactically, as feasible and effective in producing similar outcomes in postoperative atrial fibrillation reduction as well as identifies any perioperative risk factors associated with this arrhythmia.
