Abstract

Background WHO reported that neonatal hypothermia accounts for about 27% of newborn deaths worldwide. It is a serious concern in Ethiopia and other parts of sub-Saharan Africa; it poses a serious threat to global health, increasing morbidity and mortality. Hypothermic neonates are more likely to experience respiratory distress, infections and other issues that could result in longer hospital stays and delayed development. The objective of this quality improvement project was to minimise intensive medical treatments, maximise resource usage and enhance overall health outcomes for newborns at Gandhi Memorial Hospital by reducing neonatal hypothermia.

Methods Over 10 months (from 1 March 2021 to 30 January 2022), neonatal hypothermia incidence was assessed using Quality Supervision Mentoring Team and Health Management Information System data. Root cause analysis and literature review led to evidence-based interventions in a change bundle. After team training and neonatal intensive care unit (NICU) relocation, Plan-Do-Study-Act cycles tested the bundle. Close temperature monitoring and data collection occurred. Run charts evaluated intervention success against baseline data, informing conclusions about effectiveness.

Result The quality improvement project reduced neonatal hypothermia in NICU admissions from a baseline median of 80.6% to a performance median of 30%.

Conclusion and recommendation The quality improvement project at Gandhi Memorial Hospital effectively reduced neonatal hypothermia through interventions such as the temperature management bundle and NICU relocation, leading to improved patient care, fewer hypothermic neonates and enhanced body temperature management. Continuous monitoring, adherence to best practices, sharing success and outcome assessment are crucial for enhancing the project’s effectiveness and sustaining positive impacts on neonatal hypothermia reduction and patient outcomes.

WHAT IS ALREADY KNOWN ON THIS TOPIC

  • Admission hypothermia is a common problem for newborns, contributing to increased morbidity and mortality. While various temperature management protocols exist, their effectiveness in reducing admission hypothermia and the impact of neonatal intensive care unit (NICU) relocation remain unclear.

WHAT THIS STUDY ADDS

  • This quality improvement project demonstrates that implementing a temperature bundle management protocol and relocating the NICU closer to the labour ward significantly reduces the incidence of admission hypothermia.

HOW THIS STUDY MIGHT AFFECT RESEARCH, PRACTICE OR POLICY

  • These findings highlight the potential benefits of standardised temperature management protocols and strategic NICU placement for improving newborn outcomes. This could inform future research, clinical practice guidelines and hospital policies aiming to decrease admission hypothermia and its associated complications.

Introduction

Problem description

Neonatal hypothermia is a global health issue, causing around 27% of neonatal deaths, as per WHO.1 Neonatal hypothermia is a major concern in sub-Saharan Africa, including Ethiopia.2 A significant concern for global health, neonatal hypothermia raises morbidity and mortality rates. Hypothermic infants are more likely to experience respiratory distress, infections and other issues that could result in longer hospital stays and delayed development.3 The objective of this quality improvement project was to minimise intensive medical treatments, maximise resource usage and enhance overall health outcomes for newborns at Gandhi Memorial Hospital by reducing neonatal hypothermia.

Population unit

All neonates admitted to Gandhi Memorial Hospital, regardless of gestational age or birth weight, make up the project’s population unit.

Rationale/justification

Addressing alarming neonatal hypothermia (80.6%) at Gandhi Memorial Hospital’s neonatal intensive care unit (NICU) with evidence-based interventions to improve neonatal outcomes and community health.

Project context/settings

The project at Gandhi Memorial Hospital targeted NICU, operation room and labour and delivery ward to improve care for newborns. The team involved healthcare professionals from these departments to implement evidence-based interventions for at-risk infants. The project aims to enhance their health outcomes through best practices, focusing on reducing neonatal hypothermia.

Problem statement

The analysis of Quality Supervision Mentoring Team (QSMT) 24 hours activity and Health Management Information System register data from 1 March 2021 to 30 January 2022 revealed an alarmingly high incidence of hypothermia (baseline median of 80.6%) among neonates admitted to the NICUs at Gandhi Memorial Hospital. This raised serious concerns about the quality of care for fragile newborns, potentially leading to increased neonatal mortality and morbidity.

Aim statement

This healthcare quality improvement project aimed to reduce incidence of admission neonatal hypothermia from baseline performance of 80.6% to performance median of 32.2% from 1 February 2022 to 2 August 2022.

Assessment of problem and analysis of its causes

A root cause analysis identified factors contributing to neonatal hypothermia. The multidisciplinary team, including paediatricians and nurses, shared the analysis with staff, leading to targeted interventions for comprehensive issue resolution.

Interventions

Interventions tested

A temperature management bundle was developed to improve neonatal care, including elements like immediate wrapping, radiant warmer use, prewarming flannel, temperature documentation, accompanied transportation, plastic wrap availability and room heater functionality.

Meticulous measurement using an Excel template recorded and analysed each neonate’s care. Aspects of care were assigned 1 or 0 based on their presence, and columns represented individual neonates under their care. Another change proposed was relocating the NICU to the labour ward’s building for improved communication, efficiency and timely transfer of newborns requiring specialised care.

A 2023 study in china found that implementing a temperature bundle in an NICU significantly reduced the rate of admission hypothermia (from 62% to 36.9%) and improved the mean body temperature of newborns on admission (from 35.5°C to 36°C). This translated to a lower mortality rate among the infants involved.4 Another conducted in 2022 reported that using a temperature bundle in extremely low birth weight infants led to a dramatic decrease in hypothermia rates (from 92.3% to 2.5%) and increased the number of infants achieving normothermia.5 A meta-analysis study in 2021 reviewed 18 studies and concluded that temperature bundles significantly reduced the risk of hypothermia in newborns compared with standard care.6–8

Intervention design

To carry out the project, we used the nationally adopted framework called model for improvement.

Measurement of improvement

Measures chosen to assess the effects of the changes implemented included outcome measures, process measures and balancing measures.

Outcome measure

  • The proportion of hypothermic neonates at admission.

Process measures

  • The percentage of neonates transported to the NICU according to the temperature bundle management protocol.

  • Whether the NICU was near the labour ward (yes/no).

Balancing measures

  • Assessed the satisfaction of NICU and labour ward staff.

  • The incidence of neonatal hyperthermia.

Methods of data collection

The project’s success was attributed to continuous assessment and monitoring through quality improvement team meetings, coaching sessions and leadership follow-ups. Regular data collection and quality checks were ensured by QSMT duty staff.

Methods of data analysis

The study used run charts to assess process improvement. Ongoing assessment, daily monitoring, data collection and quality checks by QSMT staff facilitated a comprehensive analysis of intervention effects, providing insights into improved outcomes, process performance and system stability.

Results/effects of changes

Process measure

Interpretation of run chart

The first intervention resulted in positive improvement signals, with trend and shift rules evident, and a 71% improvement in process performance as demonstrated in the chart (figure 1).

Outcome measure using run chart

Interpretation of run chart

Intervention led to positive improvement signals as shown by the red oval designating a trend down consisting of 8 consecutive data points and the green oval representing a shift in data consisting of 8 data points below the median, reducing hypothermia incidence from 80.6% to 30% (figure 2).

The red oval designates a trend defined as seven or more contiguous data points that change in the same direction and the green oval represents a shift in data defined as seven or more contiguous data points below or above the median (Corresponding figure file: run chart showing percentage of hypothermia. tiff). NICU, neonatal intensive care unit.

Balancing measure

Over the course of the project, two balancing measure was measured. At the project’s onset, the baseline NICU and labour ward staff satisfaction rate were established at 84%, and as the project progressed, satisfaction rate became 87%. One underlying assumption was the potential for a decline in satisfaction, perhaps stemming from the perception that the quality improvement project might be seen as an additional workload by the staff. Significantly, throughout the project’s duration, there were no instances of objectively identified hyperthermia neonates resulting from the implemented intervention.

Significance of this project to neonatal mortality

Neonatal hypothermia plays a significant role in increasing neonatal death by 80% for every 1°C decrease of body temperature, especially in sub-Saharan countries.9

The project addressed neonatal hypothermia, a key factor in neonatal mortality in sub-Saharan countries. It successfully reduced hypothermia incidence in NICU admissions, it improved body temperature management. These changes positively impacted neonatal well-being and mortality rates.

Limitation and lessons learnt

Limitations

The successful outcomes in reducing neonatal hypothermia had some limitations. Accurate data documentation and protocol adherence were crucial, and incomplete or inconsistent data collection could impact accuracy. The project primarily addressed environmental, system and practice-related factors, not extensively exploring individual patient characteristics or socioeconomic factors that may also contribute to hypothermia.

Lessons learnt

The project provided valuable insights for future quality improvement efforts. Collaboration among experts drove successful change and evidence-based practices like adopting the temperature management bundle were crucial. Data-driven tools objectively measured intervention impact, and continuous monitoring and feedback ensured sustained improvements in neonatal care.

Conclusion and recommendation

Conclusion

The quality improvement project at Gandhi Memorial Hospital successfully reduced neonatal hypothermia incidence. Implementing interventions such as the temperature management bundle and relocating the NICU resulted in improved patient care, reduced hypothermic neonates and better body temperature management.

Recommendation

To enhance the project’s effectiveness, continuous monitoring, adherence to best practices and addressing challenges are recommended. Sharing the success and learnings can promote adoption of similar interventions in other healthcare facilities, contributing to broader neonatal care improvements. Ongoing staff education and outcome assessment are vital in sustaining positive impacts on neonatal hypothermia reduction and patient outcomes.
