Background TIA (Transient Ischaemic Attack) is a transient episode of neurologic dysfunction. Patients with a TIA have a high early risk of recurrent stroke. These patients need urgent initial evaluation with brain imaging, neurovascular imaging and cardiac evaluation. We conducted retrospective audit in our Acute Medical Unit (AMU) to assess waiting time and type of investigations completed as per TIA guidelines Methods All consecutive admissions with suspected TIAs were evaluated on length of stay, type of imaging tests obtained and how long they awaited for these tests. This was assessed by reviewing discharge summaries, and times and dates of scans on hospital imaging system. Results There was a total of 28 patients admitted to AMU with suspected TIA's. Of these, 16 were female and 12 were male. Mean age was 70. All patients had CT brain done on admission, two out of 28 had to wait more than 12 hours. 25 out of 28 (89%) patients got US Carotid Dopplers, and two had CT intracranial angiograms. Average waiting time for US Carotid Dopplers was 33 hours, shortest wait was 6 hours and longest was 72 hours. 14 out of 24 (58%) had inpatient heart monitoring (24h telemetry or 24h Holter) two were excluded with known atrial fibrillation, one had PPM in situ and one refused monitoring. Average length of stay in AMU was 3 days. Conclusion Patients admitted to AMU with suspected TIAs had relevant imaging and tests completed as per guidelines. 89 % had US Carotid Dopplers which were on average done 33h from admission. 58% of patients had inpatient heart monitoring. The average length of stay was 3 days but three patients stayed in AMU for up to 5 days. Protected imaging slots for AMU would expedite investigations and reduce inpatient stay.

Background: The management of patients with heart failure has been evolving given the complex nature of the disease and the increasing number of patients. Findings: Biomarkers, and in particular the natriuretic peptides, have been studied to assist with diagnosis, chronic management, and prognosis in patients with heart failure. Several new biomarkers are emerging and may be used individually or in combination with the natriuretic peptides. The use of cardiac monitoring devices and disease management programs is being established to assist in the care of patients with chronic heart failure. Interventions using phone calls, telemedicine devices, intracardiac pressure monitors, and implantable cardioverter defibrillators have been investigated. Conclusions: The combination of biomarkers, monitoring devices, and disease management programs shows promise for improving care in this challenging patient population.

Background: Clinical alarm systems safety is a national concern, specifically in intensive care units (ICUs) where alarm rates are known to be the highest. Interventional projects that examined the effect of changing default alarm settings on overall alarm rate and on clinicians' attitudes and practices toward clinical alarms and alarm fatigue are scarce. Objective: To examine if (1) a change in default alarm settings of the cardiac monitors and (2) in-service nursing education on cardiac monitor use in an ICU would result in reducing alarm rate and in improving nurses' attitudes and practices toward clinical alarms. Methods: This quality improvement project took place in a 20-bed transplant/cardiac ICU with a total of 39 nurses. We implemented a unit-wide change of default alarm settings involving 17 parameters of the cardiac monitors. All nurses received an in-service education on monitor use. Alarm data were collected from the audit log of the cardiac monitors 10 weeks before and 10 weeks after the change in monitors' parameters. Nurses' attitudes and practices toward clinical alarms were measured using the Healthcare Technology Foundation National Clinical Alarms Survey, pre- and postintervention. Results: Alarm rate was 87.86 alarms/patient day (a total of 64,500 alarms) at the preintervention period compared to 59.18 alarms/patient day (49,319 alarms) postintervention (P=.01). At baseline, Arterial Blood Pressure (ABP), Pair Premature Ventricular Contractions (PVCs), and Peripheral Capillary Oxygen Saturation (SpO2) alarms were the highest. ABP and SpO2 alarms remained among the top three at the postproject period. Out of the 39 ICU nurses, 24 (62%) provided complete pre- and postproject survey questionnaires. Compared to the preintervention survey, no remarkable changes in the postproject period were reported in nurses' attitudes. Themes in the narrative data were related to poor usability of cardiac monitors and the frequent alarms. The data showed great variation among nurses in terms of changing alarm parameters and frequency of replacing patients' electrodes. Despite the in-service, 50% (12/24) of the nurses specified their need for more training on cardiac monitors in the postproject period. Conclusions: Changing default alarm settings and standard in-service education on cardiac monitor use are insufficient to improve alarm systems safety. Alarm management in ICUs is very complex, involving alarm management practices by clinicians, availability of unit policies and procedures, unit layout, complexity and usability of monitoring devices, and adequacy of training on system use. The complexity of the newer monitoring systems requires urgent usability testing and multidimensional interventions to improve alarm systems safety and to attain the Joint Commission National Patient Safety Goal on alarm systems safety in critical care units.
