Stroke Patients: Icu Step-Down Transfers And Timing

A stroke patient's transfer from the ICU to a step-down unit depends on their recovery and the severity of their stroke. Stroke patients are often managed in the stroke ward, but those with severe strokes, constituting about 15-20% of cerebrovascular accidents, require admission into the Intensive Care Unit (ICU). The benefit of ICU admission for stroke patients is controversial, as it has been reported that there was no significant reduction in mortality and morbidity following admission. However, ICU admission can help provide intensive and specialized care for patients with severe strokes who may need support with breathing and swallowing, as well as other bodily functions.

The length of stay in the ICU depends on various factors, including the patient's age, consciousness level, and the need for mechanical ventilation. Some patients may require a prolonged stay in the ICU due to complications or the need for additional treatments and surgeries. The decision to transfer a patient from the ICU to a step-down unit is made by the healthcare team when they feel it is safe to do so and when the patient no longer requires intensive monitoring or treatments that can only be provided in the ICU.

The typical length of a hospital stay after a stroke is around five to seven days, during which the stroke care team will evaluate the effects of the stroke and determine the rehabilitation plan. The patient's rehabilitation may continue in an inpatient rehabilitation unit, a subacute rehabilitation facility, or at home with outpatient rehabilitation services, depending on their level of functional impairment.

Stroke patients requiring ICU admission have a poor prognosis

Stroke patients requiring ICU admission often have a poor prognosis. In a study of 323 patients admitted to the ICU for acute stroke, 64.5% had died within six months, with less than a fifth having a good neurological outcome.

The prognosis for stroke patients requiring ICU admission is poor, with high hospital mortality rates. In one study, 61% of patients died in hospital, with a further 16% suffering significant disability. In another study, 77.8% of stroke patients admitted to the ICU died, with only 22.2% discharged to the ward.

The high mortality rates are due to the severity of the strokes suffered by patients requiring ICU admission. In one study, 80% of patients required mechanical ventilation, with three-quarters suffering a haemorrhagic stroke. In another study, 72.2% of patients were transferred from medical wards due to a worsening clinical status requiring specialised care.

The poor prognosis for stroke patients requiring ICU admission is also due to the limited benefits of ICU admission for stroke patients. In most cases, ICU admission has been found to only prolong the inevitable demise of patients following a severe stroke.

Factors such as age and depth of coma independently predict the outcome

Age and depth of coma are two factors that independently predict the outcome of a stroke. In this context, the depth of coma refers to the Glasgow Coma Scale (GCS) score, which is used to measure levels of consciousness. A lower GCS score indicates a deeper coma.

Age is a critical factor in ischemic stroke pathology. It is the strongest non-modifiable risk factor for ischemic stroke, and aged stroke patients have higher mortality and morbidity and poorer functional recovery than younger patients. The mortality risk in ischemic stroke is high, with estimated 30-day fatality rates ranging from 16% to 32%. Aged patients have higher mortality and poorer quality of life after stroke compared with younger patients.

The depth of coma is also a significant predictor of stroke outcome. A study of 51 patients admitted to a neuro ICU with intracerebral hemorrhage (ICH) and a GCS score of eight or lower found that awakening from coma was observed in 53% of patients. Of these, 83% had an initial GCS score of seven to eight, 43% had an initial score of five to six, and 20% had an initial score of three to four. In a multivariable analysis, only a higher admission GCS score was associated with a greater likelihood of awakening from a coma.

In addition to age and depth of coma, other factors that may influence stroke outcome include sex, stroke type and severity, and the presence of comorbidities such as hypertension, diabetes, and atrial fibrillation.

Mechanical ventilation is often required for stroke patients in the ICU

Pulmonary complications such as respiratory failure, pneumonia, pleural effusions, acute respiratory distress syndrome, lung oedema, and pulmonary embolism from venous thromboembolism are common and are among the major causes of death in this group of patients.

The main goal of mechanical ventilation should be to maintain appropriate oxygen levels and tight control of carbon dioxide tension without inducing ventilator-associated lung damage.

The decision to intubate is often triggered by neurological deficits, such as a Glasgow Coma Score (GCS) of less than 9, signs of increased intracranial pressure, generalised seizures, infarct size of more than two-thirds of the middle cerebral artery territory, and midline shift on imaging.

Invasive ventilation is indicated for acute stroke patients with hypoxaemia and hypercapnia or hypocapnia. Acute respiratory failure and coma were associated with comparable survival hazard ratios, while intubation for seizure was not associated with a worse prognosis than for elective procedures.

The transfer of a critically ill patient from the OR to the ICU is an interdisciplinary task

The transfer of a critically ill patient from the OR to the ICU is a complex and risky task that requires careful planning and coordination. It involves multiple healthcare professionals and specialized equipment, and the patient's condition must be closely monitored throughout the transfer process. Here are four to six paragraphs on this topic:

The Importance of Early Recognition and Stabilization

The transfer of a critically ill patient from the OR to the ICU is a complex and interdisciplinary task that requires careful planning and coordination. Early recognition of patients at high risk is crucial, followed by preoperative and intraoperative stabilization measures. The anesthesiologist plays a key role in deciding on postoperative ICU admission and should inform the ICU staff as early as possible.

Preparation and Planning for Transfer

The transfer process should be well-planned, and locally developed checklists should be used to ensure patient safety. Trained and dedicated staff should be available, and a detailed handover using institutional flowcharts should be conducted to ensure continuity of care. The transfer equipment must be appropriate for the patient's needs and the selected transfer platform, and routes and emergency strategies should be agreed upon in advance.

Communication and Handover

Effective communication and handover are essential for a safe and smooth transfer process. Handover of care typically involves multiple stages, including agreement between referring and accepting senior clinicians, documentation, and verbal communication between the transferring and receiving teams. Clear and comprehensive documentation of the patient's condition, treatments, and any changes during transfer is crucial.

Risks and Challenges

The risks associated with transferring critically ill patients can be technical, non-technical, and organizational. Technical risks include patient and equipment-related issues, such as ventilation problems, blood pressure control, and arrhythmias. Non-technical risks include communication breakdowns and crew resource management issues. Organizational risks pertain to governance and can arise from inadequate preparation, equipment failures, or disruptions to hospital operations.

Role of Anesthesiologists and ICU Staff

Anesthesiologists should play a key role throughout the transfer process to improve patient outcomes. They are responsible for early recognition and stabilization, deciding on ICU admission, and organizing transport and handover. The ICU staff, on the other hand, provide specialized care and monitoring to optimize the patient's physiology and provide advanced organ support.

Safe Transfer Practices

Safe transfer practices include maintaining physiological targets, using checklists, and ensuring competent and well-trained staff. Transfer should only be undertaken if the benefits outweigh the potential risks, and the risks of continuing care in the patient's current location are greater. Standardized guidelines and local policies should be followed, and a clear structure of governance is essential to ensure patient safety.

The decision about ICU admission and the organisation of transport is the responsibility of the anesthesiologist

ICU, or Intensive Care Units, are reserved for patients with severe conditions that require constant monitoring and treatment. Patients in the ICU are often suffering from life-threatening illnesses or injuries and require specialised equipment and intensive care to stabilise their condition.

On the other hand, step-down units, also known as transitional care units or intermediate care units, provide an intermediate level of care for patients who no longer require intensive care but still need more attention and treatment than what is offered on a general ward.

The decision to admit a patient to the ICU or step-down unit is based on several factors, including the patient's vital signs, the severity of their illness or injury, their need for organ support or invasive monitoring, and the availability of beds and staff in the respective units.

When a stroke patient is admitted to the ICU, it is typically because they require neurological monitoring, management of stroke complications, or mechanical ventilation. In some cases, stroke patients without treatment options may be admitted to the ICU to facilitate organ donation.

The decision to transfer a stroke patient from the ICU to a step-down unit is made when the patient's condition has stabilised and they no longer require the level of care provided in the ICU. This transfer is often done in consultation with the patient's primary care team and is based on the patient's vital signs, neurological status, and the availability of beds in the step-down unit.

The anesthesiologist plays a crucial role in this decision-making process, as they have expertise in managing patients' airways, breathing, circulation, and pain. They work closely with the patient's primary care team to determine the most appropriate level of care and organise the necessary transport between units.

The organisation of transport is also the responsibility of the anesthesiologist, who ensures that the patient is safely and comfortably transferred between units while maintaining the necessary level of care and monitoring. This may involve coordinating with other medical staff, such as nurses and respiratory therapists, to ensure a smooth and efficient transfer.

In summary, the anesthesiologist plays a vital role in deciding when a stroke patient is ready to be transferred from the ICU to a step-down unit and in organising the safe and appropriate transport of the patient between units. This decision is made in the best interests of the patient and involves collaboration with the patient's primary care team and other medical staff.
