A comparative study examining the decision-making processes of medical and nursing staff in weaning patients from mechanical ventilation

Physicians' decision making when weaning patients from mechanical ventilation: A qualitative content analysis

BACKGROUND

Weaning from mechanical ventilation is a complex and central intensive care process. This complexity indicates that the challenges of weaning must be explored from different perspectives. Furthermore, physicians' experiences and the factors influencing their decision-making regarding weaning are unclear.

OBJECTIVES

This study aimed to explore and describe the factors influencing physicians' decision-making when weaning patients from invasive mechanical ventilation in Swedish intensive care units (ICUs).

METHODS

This qualitative study used an exploratory and descriptive design with qualitative content analysis. Sixteen physicians from five ICUs across Sweden were purposively included and interviewed regarding their weaning experiences.

FINDINGS

The physicians expressed that prioritising the patient's well-being was evident, and there was agreement that both the physical and mental condition of the patient had a substantial impact on decision-making. Furthermore, there was a lack of agreement on whether patients should be involved in the weaning process and how their resources, needs, and wishes should be included in decision-making. In addition, there were factors not directly linked to the patient but which still influenced decision-making, such as the available resources and teamwork. Sometimes, it was difficult to point out the basis for decisions; in that decisions were made by gut feeling, intuition, or clinical experience.

CONCLUSION

Physicians' decision-making regarding weaning was a dynamic process influenced by several factors. These factors were related to the patient's condition and the structure for weaning. Increased understanding of weaning from the physicians' and ICU teams' perspectives may improve the weaning process by broadening the knowledge about the aspects influencing the decision-making.

Clinical practice, decision-making, and use of clinical decision support systems in invasive mechanical ventilation: a narrative review

Invasive mechanical ventilation is a key supportive therapy for patients on intensive care. There is increasing emphasis on personalised ventilation strategies. Clinical decision support systems (CDSS) have been developed to support this. We conducted a narrative review to assess evidence that could inform device implementation. A search was conducted in MEDLINE (Ovid) and EMBASE. Twenty-nine studies met the inclusion criteria. Role allocation is well described, with interprofessional collaboration dependent on culture, nurse:patient ratio, the use of protocols, and perception of responsibility. There were no descriptions of process measures, quality metrics, or clinical workflow. Nurse-led weaning is well-described, with factors grouped by patient, nurse, and system. Physician-led weaning is heterogenous, guided by subjective and objective information, and 'gestalt'. No studies explored decision-making with CDSS. Several explored facilitators and barriers to implementation, grouped by clinician (facilitators: confidence using CDSS, retaining decision-making ownership; barriers: undermining clinician's role, ambiguity moving off protocol), intervention (facilitators: user-friendly interface, ease of workflow integration, minimal training requirement; barriers: increased documentation time), and organisation (facilitators: system-level mandate; barriers: poor communication, inconsistent training, lack of technical support). One study described factors that support CDSS implementation. There are gaps in our understanding of ventilation practice. A coordinated approach grounded in implementation science is required to support CDSS implementation. Future research should describe factors that guide clinical decision-making throughout mechanical ventilation, with and without CDSS, map clinical workflow, and devise implementation toolkits. Novel research design analogous to a learning organisation, that considers the commercial aspects of device design, is required.

Occurrence of Dysrhythmias During Ventilatory Weaning and Its Association With Length of Mechanical Ventilation and In-hospital Complications

BACKGROUND

The occurrence of cardiac dysrhythmias during ventilatory weaning and its impact on the length of ventilation and occurrence of complications have not been systematically investigated.

OBJECTIVES

The aim of this study was to evaluate the association between cardiac dysrhythmias during weaning and the duration of ventilation and complications during ventilator weaning.

METHOD

Data on the length of ventilation and complications were collected from the medical records of 30 mechanically ventilated patients. Continuous electrocardiographic recordings were collected at baseline and during the initial weaning trial. Multiple regression analysis was used to evaluate the association between dysrhythmias and length of ventilation. The relationship between prolonged ventilation and complications was assessed using the χ2 analysis.

RESULTS

Supraventricular ectopic beats during weaning positively predicted the length of ventilation (P < .01). Prolonged ventilation (>7 days) is associated with the occurrence of renal insufficiency and septicemia.

CONCLUSION

The association between the occurrence of supraventricular ectopic beats during ventilator weaning and the length of ventilation requires further evaluation and tailored management to improve patient outcomes.

Reasoning like a doctor or like a nurse? A systematic integrative review

When physicians and nurses are looking at the same patient, they may not see the same picture. If assuming that the clinical reasoning of both professions is alike and ignoring possible differences, aspects essential for care can be overlooked. Understanding the multifaceted concept of clinical reasoning of both professions may provide insight into the nature and purpose of their practices and benefit patient care, education and research. We aimed to identify, compare and contrast the documented features of clinical reasoning of physicians and nurses through the lens of layered analysis and to conduct a simultaneous concept analysis. The protocol of this systematic integrative review was published doi: 10.1136/bmjopen-2021-049862. A comprehensive search was performed in four databases (PubMed, CINAHL, Psychinfo, and Web of Science) from 30th March 2020 to 27th May 2020. A total of 69 Empirical and theoretical journal articles about clinical reasoning of practitioners were included: 27 nursing, 37 medical, and five combining both perspectives. Two reviewers screened the identified papers for eligibility and assessed the quality of the methodologically diverse articles. We used an onion model, based on three layers: Philosophy, Principles, and Techniques to extract and organize the data. Commonalities and differences were identified on professional paradigms, theories, intentions, content, antecedents, attributes, outcomes, and contextual factors. The detected philosophical differences were located on a care-cure and subjective-objective continuum. We observed four principle contrasts: a broad or narrow focus, consideration of the patient as such or of the patient and his relatives, hypotheses to explain or to understand, and argumentation based on causality or association. In the technical layer a difference in the professional concepts of diagnosis and the degree of patient involvement in the reasoning process were perceived. Clinical reasoning can be analysed by breaking it down into layers, and the onion model resulted in detailed features. Subsequently insight was obtained in the differences between nursing and medical reasoning. The origin of these differences is in the philosophical layer (professional paradigms, intentions). This review can be used as a first step toward gaining a better understanding and collaboration in patient care, education and research across the nursing and medical professions.

L’autonomie décisionnelle d’infirmières de soins intensifs lors du sevrage de la ventilation mécanique : une analyse de concept

Nurses have a leading role in weaning patients from mechanical ventilation (WMV) given their constant presence and their continuous monitoring. To promote proper WMV, nurses must exercise autonomy and be involved in decision-making. However, in certain care contexts, there is little involvement of nurses. The purpose of this text is to establish the characteristics of the concept of autonomous decision-making applied to nursing during WMV. An analysis of this concept was carried out according to the evolutionary method of Rodgers. The identification of the attributes, antecedents, and consequences made it possible to note ambiguity in the definition of this concept. Nurses use autonomous decision-making for the execution of assigned tasks and when they make decisions according to a pre-prescribed decision-making algorithm. Significant foundations for the decision-making autonomy of critical care nurses during WMV emerged from this analysis&#160;: scope of practice, in-depth knowledge of the patient, and commitment to the success of WMV. Participation in interdependent decision-making allows nurses to bring the patient&#8217;s perspective into decisions. Avenues of reflection have also emerged, including decisions based on evidence to provide new avenues for autonomous decision-making.

Continuous care and patients' basic needs during weaning from mechanical ventilation: A qualitative study

BACKGROUND

Mechanical ventilation is associated with a number of risks and complications. Thus, rapid and safe weaning from mechanical ventilation is of great importance. Weaning is a complex and challenging process, requiring continuous care and knowledge of the patient.

AIMS

The aim of the present study was to describe the continuous care process during weaning as well as to analyse the facilitators and obstacles to the weaning process from start to finish from the perspective of intensive care unit (ICU) staff, particularly nurses.

RESEARCH DESIGN

Twenty-two ICU staff members, including nurses and physicians, and three patients hospitalised in the ICU were enrolled in this qualitative study. Semi-structured interviews were used for data collection and the transcripts were analysed using qualitative content analysis.

FINDINGS

'Continuous care' was found to be the patients' basic need during weaning from mechanical ventilation. Uninterrupted, stable, comprehensive and dynamic care and monitoring with immediate response to all physiological and psychological changes were features of continuous care. The three main themes identified by this study were time spent with the patient, comprehensive supervision and maintenance of the quality of care during shifts.

CONCLUSION

Continuous and constant care should be provided during the weaning process. Such care will help to provide health care staff with a deeper understanding of the patient and his or her continuous changes, leading to a timely and favourable response during weaning. To achieve this goal, skill, communication and organisational changes are essential.

The use of a weaning and extubation protocol to facilitate effective weaning and extubation from mechanical ventilation in patients suffering from traumatic injuries: a non-randomized experimental trial comparing a prospective to retrospective cohort

PURPOSE

Many patients who have suffered traumatic injuries require mechanical ventilation (MV). Weaning is the transition from ventilatory support to spontaneous breathing. The purpose of this study was to determine whether the use of a nurse and a physiotherapist-driven protocol to wean and extubate patients from MV resulted in decreased MV days and intensive care unit (ICU) length of stay (LOS).

METHODS

A prospective cohort of 28 patients (Phase I), weaned according to the protocol developed for the Union Hospital Trauma Unit, was matched retrospectively with a historical cohort of 28 patients (Phase II), weaned according to physician preference. Pairs in the two groups were matched for gender, age, type, and severity of injury.

RESULTS

For mean MV days, the groups did not differ statistically significantly (p 0.3; 14.4 days vs. 16.3 days), although the reduction in MV is clinically significant in view of the complications of additional MV days. The difference of 0.2 days for ICU LOS was not statistically significant (p = 0.9; 20.8 days vs. 21.0 days) demonstrating that the reduction in MV days may not result in the reduction of ICU LOS. The rate of re-intubation was similar between the groups (Phase I = 3/28 vs. Phase II = 4/24).

CONCLUSION

The use of a weaning and extubation protocol led by nursing staff and physiotherapists resulted in a clinically significant reduction in MV time, reducing risk of ventilator-associated complications. The role of physiotherapists and nursing staff in weaning and extubation from MV could be greatly expanded in South African ICUs.

Anaesthetists' perceptions of facilitative weaning strategies from mechanical ventilator in the intensive care unit (ICU): a qualitative interview study

AIM

This study aimed to examine anaesthetists' perceptions of facilitative weaning from the mechanical ventilator in the intensive care unit (ICU).

METHODS

Explorative qualitative interviews in a phenomenographic reference frame with a purposive sample of 14 eligible anaesthetists from four different ICUs with at least one year of clinical experience of ICU and of ventilator weaning.

FINDINGS

Four categories of anaesthetists' perceptions of facilitative decision-making strategies for ventilator weaning were identified. These were the instrumental, the interacting, the process-oriented and the structural strategies" for ventilator weaning. The findings refer to a supportive multidisciplinary holistic ICU quality of care. Choice of strategy for ventilator weaning was flexible and individually tailored to the patients'.

CONCLUSIONS

Choice of strategy was flexible and individually adjustable. Introduction of evidence-based guidelines from ventilator weaning is necessary in the ICU. The guidelines should also cover the responsibilities of various professional groups. Regular evaluations of methods and strategies used in practice need to be implemented. This may facilitate decision-making strategies for ventilator weaning in practice at the ICU. Greater attention needs to focus on family members' experiences. The strategies should be an integral part of continuous staff training.

The association between bathing and weaning trial duration

OBJECTIVE

To describe patterns of bath care for patients who are weaning from prolonged mechanical ventilation (PMV) and to explore the association between bathing and weaning trial duration.

METHODS

Descriptive correlational study. Clinical records from 439 weaning trial days for 30 patients who required PMV were abstracted for bathing occurrences during weaning trials, within 1 hour before a trial, and nocturnally.

RESULTS

Most baths occurred during weaning trials (30.8%) or at night (35.3%), and less frequently (16%) within 1 hour before a trial. No significant effects were found on trial duration for nocturnal bathing or bathing within 1 hour before a trial. By using random coefficient modeling, weaning duration was shown to be longer when bathing occurred during a weaning trial (P < .05), even when controlling for age, severity of illness, and days on bedrest.

CONCLUSION

Bathing occurred during approximately one third of PMV weaning trials. Baths during PMV weaning trials were associated with longer weaning trial duration.

Wash and wean: bathing patients undergoing weaning trials during prolonged mechanical ventilation

BACKGROUND

Bathing is a fundamental nursing care activity performed for or with the self-assistance of critically ill patients. Few studies address caregiver or patient-family perspectives about bathing activity during weaning from prolonged mechanical ventilation (PMV).

OBJECTIVE

To describe practices and beliefs about bathing patients during weaning from PMV.

METHODS

Secondary analysis of qualitative data (observational field notes, interviews, and clinical record review) from a larger ethnographic study involving 30 patients weaning from PMV and the clinicians who cared for them using basic qualitative description.

RESULTS

Bathing, hygiene, and personal care were highly valued and equated with "good" nursing care by families and nurses. Nurses and respiratory therapists reported "working around" bath time and promoted conducting weaning trials before or after bathing. Patients were nevertheless bathed during weaning trials despite clinicians' expressed concerns for energy conservation. Clinicians recognized individual patient response to bathing during PMV weaning trials.

CONCLUSION

Bathing is a central care activity for patients on PMV and a component of daily work processes in the intensive care unit. Bathing requires assessment of patient condition and activity tolerance and nurse-respiratory therapist negotiation and accommodation with respect to the initiation or continuation of PMV weaning trials during bathing. Further study is needed to validate the impact (or lack of impact) of various timing strategies for bathing patients who are on PMV.

Nurses' conceptions of facilitative strategies of weaning patients from mechanical ventilation--a phenomenographic study

BACKGROUND

Mechanical ventilator withdrawal can amount up to 40% of total ventilator time. Being on a mechanical ventilator is associated with risk of anxiety, post-traumatic stress syndrome, nosocomial pneumonia and premature mortality.

PURPOSE

The purpose of the present study was to describe different conceptions of nurses' facilitating decision-making strategies regarding weaning patients from mechanical ventilations cared for in intensive care unit (ICU).

METHOD

Semi-structured interviews were analysed within the phenomenographic framework. Twenty ICU nurses were interviewed.

FINDINGS

The findings revealed three main categories of nurses' facilitating decision-making strategies: "The intuitive and interpretative strategy" featured nurses' pre-understandings. "The instrumental strategy" involved analysis and assessment of technological and physiological parameters. "The cooperative strategy" was characterised by interpersonal relationships in the work situation. Absence of a common strategy and lack of understanding of others' strategies were a source of frustration. The main goals were to end mechanical ventilator support, create a sense of security, and avoid further complications.

CONCLUSION

Although these findings need to be confirmed by further studies we suggest that nurses' variable use of individual strategies more likely complicate an efficient and safe weaning process of the patients from mechanical ventilation.

Critical care nurses' decision making: sedation assessment and management in intensive care

AIMS

This study was designed to examine the decision making processes that nurses use when assessing and managing sedation for a critically ill patient, specifically the attributes and concepts used to determine sedation needs and the influence of a sedation guideline on the decision making processes.

BACKGROUND

Sedation management forms an integral component of the care of critical care patients. Despite this, there is little understanding of how nurses make decisions regarding assessment and management of intensive care patients' sedation requirements. Appropriate nursing assessment and management of sedation therapy is essential to quality patient care.

DESIGN

Observational study.

METHODS

Nurses providing sedation management for a critically ill patient were observed and asked to think aloud during two separate occasions for two hours of care. Follow-up interviews were conducted to collect data from five expert critical care nurses pre- and postimplementation of a sedation guideline. Data from all sources were integrated, with data analysis identifying the type and number of attributes and concepts used to form decisions.

RESULTS

Attributes and concepts most frequently used related to sedation and sedatives, anxiety and agitation, pain and comfort and neurological status. On average each participant raised 48 attributes related to sedation assessment and management in the preintervention phase and 57 attributes postintervention. These attributes related to assessment (pre, 58%; post, 65%), physiology (pre, 10%; post, 9%) and treatment (pre, 31%; post, 26%) aspects of care.

CONCLUSIONS

Decision making in this setting is highly complex, incorporating a wide range of attributes that concentrate primarily on assessment aspects of care.

RELEVANCE TO CLINICAL PRACTICE

Clinical guidelines should provide support for strategies known to positively influence practice. Further, the education of nurses to use such guidelines optimally must take into account the highly complex iterative process and wide range of data sources used to make decisions.

A nurse's guide to common mechanical ventilation techniques and modes used in infants. Nursing implications

The need for conventional mechanical ventilation (CMV) is a common one in the neonatal intensive care unit (NICU). The goals of CMV are to facilitate adequate gas exchange, minimize the risk of lung injury/damage, decrease the patient's work of breathing, and optimize the patient's comfort. Although time-cycled, pressure-limited ventilation remains the most common CMV modality, volume-cycled ventilation, assist-control ventilation, pressure-support ventilation, and pressure-control ventilation are sometimes used in the NICU. Pressure-regulated volume control, volume-guaranteed ventilation, volume-assured pressure-support ventilation, and proportional-assist ventilation are emerging hybrid modes of CMV. Although CMV is frequently life saving, it can cause complications if improperly used. Nurses are responsible for the ongoing assessment and care of infants undergoing CMV and are becoming frequently more involved in the weaning process of CMV. This article provides an overview of conventional ventilation, with a focus on common modalities, and ventilation-related nursing interventions.
