Unique Critical Care Nursing Dissertation Topics With Research Aims

 

Topic 1. Quantitative Study on the Impact of Nurse-Led Prone Positioning Teams on Outcomes in ARDS Patients

 

Research Aim: This study aims to find out if specially trained nursing teams can improve breathing and reduce ICU stay in patients with severe lung problems by using a technique called prone positioning, where patients lie on their stomachs. It will compare recovery rates with and without nurse-led interventions.

Research Aim: This study will explore how ICU nurses feel and what they go through when helping with organ donation after a patient is declared brain dead. It aims to understand the emotional, ethical, and professional challenges nurses face and what support they need during this sensitive process.

Research Aim: This research looks at whether giving nurses real-time alerts on digital screens about a patient’s condition helps them react faster when a patient’s health is getting worse. The goal is to see if technology can improve care and prevent emergencies before they become life-threatening.

Research Aim: Martha’s Rule lets patients and families in acute hospitals in England request an urgent review from a separate clinical team when they are worried that a patient is deteriorating.

This study will audit anonymised requests answered by one critical care outreach team, describing who called, the concerns raised, response times and whether care was escalated.

Research Aim: This study will explore how critical care nurses view involving relatives in preventing and managing delirium, such as helping with reorientation, bringing familiar objects and supporting sleep.

A survey of nurses in adult intensive care units, followed by interviews, will examine current practice, perceived benefits and risks, visiting arrangements and the training nurses would need.

Research Aim: This study will survey nurse leads of adult intensive care units in England about rehabilitation and follow-up after critical illness.

It will compare reported practice, including rehabilitation goals, handover to ward teams, follow-up clinics and peer support, with NICE recommendations, and explore the staffing and funding barriers that nurse leads describe.

Research Aim: UK standards for intensive care set minimum nurse-to-patient ratios and expect at least half of registered nurses to hold a post-registration critical care qualification.

This study will interview critical care nurse managers about how they maintain these standards during shortages, including redeploying ward nurses, using temporary staff and changing skill mix.

Research Aim: Some intensive care units run programmes that invite families to share small final wishes for a dying patient, such as music, a favourite food or a keepsake.

Interviews with critical care nurses will explore how wishes are identified and fulfilled, perceived effects on families and on nurses’ wellbeing, and barriers such as time, cost and infection control.

Frequently Asked Questions

Start with a problem you have seen in intensive care or on a ward, such as delayed discharge, delirium or families’ distress, and search CINAHL, MEDLINE and the journal Nursing in Critical Care for reviews.

National standards, such as the Guidelines for the Provision of Intensive Care Services, show where practice may fall short. Then check you can reach data or participants in time.

Current themes include recognising deterioration and critical care outreach, delirium and sedation, family presence, rehabilitation after critical illness, nurse staffing and skill mix, moral distress, end-of-life care in intensive care, and technology at the bedside, such as smart infusion pumps and electronic charting.

Rarely. Many intensive care patients cannot consent while critically ill, so studies involving them need NHS ethics review and special consent arrangements, and undergraduate students cannot apply for these approvals.

Feasible designs include literature reviews, audits, analysis of published data, surveys of nurses recruited through professional networks, and interviews with intensive care survivors or relatives recruited through charities with university ethics approval.

Largely, yes. In the UK, critical care covers intensive care units for the sickest patients and high dependency units, together with outreach teams that support deteriorating patients on wards and follow-up services after discharge.

ICU topics sit at the centre of critical care nursing, but outreach, ward and follow-up topics count too.

National audit bodies publish summary reports: ICNARC covers adult critical care in England, Wales and Northern Ireland, and the Scottish Intensive Care Society Audit Group covers Scotland. NICE guidance and the Guidelines for the Provision of Intensive Care Services give standards to compare against.

Patient-level data from your own unit need local approval, so plan any audit early.
