Background Cardioembolism in paroxysmal atrial fibrillation (PAF) is a preventable cause of transient ischaemic attack (TIA) or ischaemic stroke, however, due its transient nature, a short-duration Holter monitor may miss a significant proportion of events. Methods We conducted an open-label randomised controlled trial of cardiac monitoring after a TIA or ischaemic stroke comparing a 14-day ECG monitoring patch with short-duration Holter monitoring for the detection of PAF. The primary outcome was the detection of one or more episodes of ECG-documented PAF lasting at least 30 seconds within 90 days in each of the study arms. A budget impact analysis from the healthcare perspective was performed to assess the theoretical economic implications of the patch-based service versus Holter monitoring. Based on the AF detection rates found in this study, Hospital Episode Statistics data for the incidence of stroke and TIA (October 2016-September 2017) and National Health Service reference costs, the cost-effectiveness of the patch-based service versus Holter monitoring was calculated. The Sentinel Stroke National Audit Programme estimate of £13,452 was used as the mean year one direct medical cost of a stroke. Results From February 2016 through February 2017, 43 (76.8%) of the 56 patients assigned to the patch-based monitoring group and 47 (78.3%) of the 60 patients assigned to the short-duration Holter monitoring group had successful monitor placement with 90 days of follow-up (Figure 1). Of the 26 protocol failures between the two groups, 23 (88.5%) were due to patient refusal for outpatient short-duration Holter monitor placement, whilst only 1 (3.8%) was due to unsuccessful patch placement. The rate of detection of PAF at 90 days was 16.3% in the patch-based monitoring group (7 patients) compared to 2.1% in the short-duration Holter monitoring group (1 patient), with an odds ratio of 8.9 (95% CI 1.1–76.0; P=0.026). Implementation of the patch-based service at our hospital would result in 10.8 more strokes avoided per year compared to current practice with short-duration Holter monitoring. This would equate to a yearly saving in direct medical costs of £57,481, increasing to £106,342 over 5 years. When social care costs are included, incremental savings of £154,716 can be achieved in the first year and £410,449 at 5 years. In addition, an analysis of the potential reduction in outpatient follow-up appointment costs resulted in a further saving of £56,149, giving a total potential saving of £113,630 over the first year with the use of the patch-based service compared to short-duration Holter monitoring, increasing to £162,491 over 5 years.

Summary Specific patient groups consisting of those with nasogastric or gastrostom feeding tubes such as those with stroke neurological impairment or other etiologies, patients with difficulty swallowing (i.e. oral pharyngeal dysfunction), unconscious patients and children who dislike or refuse taking or cannot swallow tablets require special attention with regard to the pharmacological treatment of acid‐related disorders. In particular, these groups of patients require special formulations in order to achieve optimal compliance with acid suppression therapy. Formulations such as the syrup histamine (H2)‐receptor antagonist in a syrup formulation, or for proton pump inhibitors, either the multiple unit pellet capsules, fast dissolving tablets or intravenous formulations, can be used to overcome swallowing problems or bitter taste.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
