Perception of discomfort by mechanical ventilation patients in the Intensive Care Unit: A qualitative study

Managing Chronic Pain in Ventilated Critical Care Patients

Pain experienced by mechanically ventilated patients in intensive care units (ICUs) is often overlooked, but it is a significant issue. With over 5 million annual ICU admissions in the United States, the prevalence of pain during hospitalization and its aftermath is a pressing concern. Chronic pain in ICU survivors has been linked to post-traumatic stress disorder, poor quality of life, and long-term impairments known as postintensive care syndrome. Barriers to effective pain management include psychological factors, sedation restrictions, and inadequate use of valid assessment tools.

Critically ill patients' experiences of discomfort and comfort in the intensive care unit: A qualitative descriptive study

BACKGROUND

The physiological state of critically ill patients is severely impaired by illness or trauma and is uncomfortable. Such experiences cause long-term anxiety and post-traumatic stress disorder.

OBJECTIVE

This study aimed to understand discomfort and comfort based on the experiences of critically ill adult patients in the intensive care unit and to explore ways to improve their comfort.

METHODS

This qualitative descriptive study was conducted with 15 critically ill patients (age range: 46-81 years; six females) in the intensive care unit using semistructured interviews and participant observation. The data collected were analysed using Braun and Clarke's thematic analysis. Data were collected from the intensive care unit and general ward of a university hospital in Japan.

FINDINGS

Six themes related to discomfort and comfort were identified. The three themes related to discomfort were "overlapping uncertainties", "being unable to control physical discomfort", and "having to endure psychologically and situationally". The three themes related to comfort were "feeling connected brings calm", "routine care relieves pain and thirst", and "ease when one can decide for oneself". Participants' discomfort involved physical and psychological factors and was related to treatments, procedures, care, and the environment. Moreover, more than half of the patients endured unmet needs. Comfort was brought about by providing routine care for physical discomforts that critically ill patients often experience, feeling alive and connected to others and encouraging independence.

CONCLUSION

Recognising the potential for physical and psychological discomfort, as well as communication and other difficulties, in critically ill patients is crucial. Patients may also experience discomfort when healthcare providers take the lead, which underscores the importance of involving patients in their care. By showing respect for patients' intentions and involving them in decision-making, healthcare providers can improve patient comfort and promote a more collaborative approach to care.

Prevalence and risk factors of subsyndromal delirium in ICU: A systematic review and meta-analysis

OBJECTIVE

To systematically assess the prevalence and risk factors for subsyndromal delirium (SSD) in the intensive care unit.

DESIGN

A systematic reviewand meta-analysis.

METHODOLOGY

This systematic review and meta-analysis was conducted in eight databases, including PubMed, Web of Science, Ovid,Scopus, China Knowledge Resource Integrated Database, Wanfang Database,Weipu Database and Chinese Biomedical Database. All original observational studies of subsyndromal delirium in the ICU were included, with languages limited to English and Chinese. The methodological quality was assessed by the Newcastle-Ottawa Scale and the Agency for Healthcare Research and Quality recommendation checklist. Meta-analysis was performed using Stata software (version 18.0).

RESULT

A total of 27 studies involving 7,286 participants were included in this review. The pooled prevalence of SSD was 32.4 % (95 %CI: 27.1 %-37.7 %).Fourteen studies reported 34 independent risk factors, and the following ten factors were significantly associated with SSD: older age, higher Acute Physiology and Chronic Health Evaluation II (APACHE II) score, lower Mini-mental Status Examination (MMSE) score, pain, mechanical ventilation, hypoproteinemia, blood transfusion, longer ICU stay, infection, and physical restraint.

CONCLUSION

We conducted a systematic review and meta-analysis to evaluate the prevalence of SSD in the ICU and identified 10 risk factors associated with SSD. However, the studies have significant heterogeneity, future research should be conducted in multicenter with large samples to strengthen the current evidence.

IMPLICATIONS FOR CLINICAL PRACTICE

Subsyndromal delirium is a frequently occurring adverse event in the ICU, so it is recommended that clinicians and nurses incorporate the assessment of SSD into their daily routine. In this study, we also identified ten risk factors associated with SSD, and some of which could be modified or intervened. These findings provide a basis for ICU medical staff to identify patients at high risk of SSD and then implement individualized interventions to reduce the prevalence of SSD.

Measuring pain or discomfort during routine nursing care in lightly sedated mechanically ventilated intensive care patients: A prospective preliminary cohort study

BACKGROUND

Pain is routinely measured on mechanically ventilated ICU patients. However, the tools used are not designed to discriminate between pain and non-pain discomfort, a distinction with therapeutic implications.

OBJECTIVES

To evaluate whether clinical measurement tools can discern both pain and non-pain discomfort.

METHODS

A prospective observational cohort study was conducted in a General ICU at a tertiary Medical Center in Israel. The Behavior Pain Scale (BPS) and Visual Analog Scale (VAS) of Discomfort were simultaneously assessed by a researcher and bedside nurse on thirteen lightly sedated patients during 71 routine nursing interventions in lightly sedated, mechanically ventilated, adult patients. Patients were asked whether they were in pain due to these interventions.

RESULTS

Statistically significant increases from baseline during interventions were observed [median change: 1.00 (-1-5), 1.5(-4-8.5), p < 0.001] as measured by BPS and VAS Discomfort Scale, respectively. BPS scores ranged between 4 and 6 when the majority (53 %) of the patients replied that they had no pain but were interpreted by the clinicians as discomfort. Endotracheal suctioning caused the greatest increase in BPS and VAS, with no statistically significant differences in BPS and VAS Discomfort Scale scores whether patients reported or did not report pain. A BPS>6 had a higher sensitivity and specificity to reported pain (accuracy of 76 %) compared to a BPS of 4-6.

CONCLUSIONS

Standard assessments are sensitive to pain caused by routine nursing care interventions. However, this study presents evidence that among lightly sedated ICU patients, moderate BPS scores could also measure non-pain discomfort. ICU nurses should be aware that signs of unpleasantness measured by a pain scale could reflect non-pain discomfort.

Exploring the Experience of Patients Who Received Mechanical Ventilation Support during Their Intensive Care Unit Stay

OBJECTIVE

The objective of this study is to explore the experiences of patients who received mechanical ventilation (MV) support during their intensive care unit (ICU) stay in Jordan.

METHODS

A phenomenological hermeneutic approach was conducted, informed by the philosophy of Martin Heidegger. Fifteen patients participated in interviews regarding their experiences during their time in the critical care unit of three public hospitals in Jordan. Interpretive Phenomenological Analysis (IPA) was used to analyse the data.

FINDINGS

The findings of the current study indicated that patients who received MV support during their ICU stays experienced both physical and psychological suffering. A pattern of shared experiences among intensive care patients was identified. Five main themes captured the patients' experiences: (1) feeling powerless, (2) being unable to recognise time, (3) feeling dead, (4) experiencing physical pain, and (5) having future concerns.

CONCLUSION

The current study found that mechanically ventilated ICU patients suffer both physically and psychologically. Nurses should use specific strategies to relieve discomfort in addition to pain treatment. This is especially essential for non-verbal patients, whose actions may resemble those of their clinicians in pain.

Dexmedetomidine for analgesia and sedation in newborn infants receiving mechanical ventilation

BACKGROUND

Dexmedetomidine is a selective alpha-2 agonist with minimal impact on the haemodynamic profile. It is thought to be safer than morphine or stronger opioids, which are drugs currently used for analgesia and sedation in newborn infants. Dexmedetomidine is increasingly being used in children and infants despite not being licenced for analgesia in this group.

OBJECTIVES

To determine the overall effectiveness and safety of dexmedetomidine for sedation and analgesia in newborn infants receiving mechanical ventilation compared with other non-opioids, opioids, or placebo.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, and two trial registries in September 2023.

SELECTION CRITERIA

We planned to include randomised controlled trials (RCTs) and quasi-RCTs evaluating the effectiveness of dexmedetomidine compared with other non-opioids, opioids, or placebo for sedation and analgesia in neonates (aged under four weeks) requiring mechanical ventilation.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were level of sedation and level of analgesia. Our secondary outcomes included days on mechanical ventilation, number of infants requiring additional medication for sedation or analgesia (or both), hypotension, neonatal mortality, and neurodevelopmental outcomes. We planned to use GRADE to assess the certainty of evidence for each outcome.

MAIN RESULTS

We identified no eligible studies for inclusion. We identified four ongoing studies, two of which appear to be eligible for inclusion; they will compare dexmedetomidine with fentanyl in newborn infants requiring surgery. We listed the other two studies as awaiting classification pending assessment of full reports. One study will compare dexmedetomidine with morphine in asphyxiated newborns undergoing hypothermia, and the other (mixed population, age up to three years) will evaluate dexmedetomidine versus ketamine plus dexmedetomidine for echocardiography. The planned sample size of the four studies ranges from 40 to 200 neonates. Data from these studies may provide some evidence for dexmedetomidine efficacy and safety.

AUTHORS' CONCLUSIONS

Despite the increasing use of dexmedetomidine, there is insufficient evidence supporting its routine use for analgesia and sedation in newborn infants on mechanical ventilation. Furthermore, data on dexmedetomidine safety are scarce, and there are no data available on its long-term effects. Future studies should address the efficacy, safety, and long-term effects of dexmedetomidine as a single drug therapy for sedation and analgesia in newborn infants.

Multidisciplinary staff perceived barriers and enablers to early mobilization of patients with burns in the ICU

BACKGROUND

Complex challenges face clinicians managing critically ill patients with burns, particularly in the context of enhancing outcomes after a stay in ICU. Compounding this, a dearth of research explores the specific and modifiable factors that impact early mobilization in the ICU environment.

AIM

To explore the barriers and enablers of early functional mobilization for patients with burns in the ICU from a multidisciplinary perspective.

DESIGN

A qualitative phenomenological study.

METHODS

Semi-structured interviews supplemented by online questionnaires conducted with 12 multidisciplinary clinicians (four doctors, three nurses and five physical therapists) who previously managed burn patients at a quaternary level ICU. Data were thematically analysed.

RESULTS

Four main themes: patient, ICU clinicians, the workplace and the physical therapist were identified as impacting on early mobilization. Subthemes identified barriers or enablers to mobilization but all were strongly influenced by overarching theme of the clinician's "emotional filter." Barriers included high levels of pain, heavy sedation and low levels of clinician exposure to treating patients with burns. Enablers included higher levels of clinician's experience and knowledge about burn management and benefits of early mobilization; increased coordinated staff resources when undertaking mobilization; and, open communication and positive culture towards early mobilization across the multidisciplinary team.

CONCLUSION

Patient, clinician and workplace barriers and enablers were identified to influencing the likelihood of achieving early mobilization of patients with burns in the ICU. Emotional support for staff through multidisciplinary collaboration and development of structured burns training program were key recommendations to address barriers and strengthen enablers to early mobilization of patients with burns in the ICU.

A qualitative study of nurses' perception on patients' thirst in intensive care units

BACKGROUND

Thirst is a prevalent and intense symptom among patients in intensive care units. Occurrence of thirst in the intensive care unit cannot be avoided because of the nature of critical illnesses and their treatments like the side effects of administered medication or dehydration. In the intensive care unit, nurses have the opportunity and responsibility to prevent and reduce thirst by recognizing the different types of thirst. Thus, knowing nurses' perception on patients' thirst is crucial.

OBJECTIVES

Exploration of intensive care nurses' perception on patients' thirst.

RESEARCH DESIGN

A qualitative descriptive study.

METHODS

Data were collected from December 2020 to January 2021 and analyzed by using a phenomenographic methodology. Data were transcribed verbatim and thematic analysis was performed.

RESULTS

Sixteen nurses, in Chongqing, China, aged 25-48 years, were interviewed. Four themes emerged: (1) perceived barriers for thirst; (2) perceived signs of thirst; (3) perceived reasons of thirst; (4) perceived consequences for thirst. Overall nurses' perception of patients' thirst is poor. Nurses give a low priority and insufficient attention to the issue of thirst in intensive care patients.

CONCLUSION

Intensive care nurses' perception on thirst in patients should be evaluated and, if necessary, this issue should be given more attention in training in order to create sufficient awareness about the topic.
