Exploring the Patient Experience with Noninvasive Ventilation: A Human-Centered Design Analysis to Inform Planning for Better Tolerance

Patient and caregiver perceptions of oxygen therapy in facility-based settings for acute hypoxemic conditions: a scoping review

Background

Access to oxygen therapy is essential for ensuring a functioning health care system. Despite its widespread application across multiple patient groups and all ages, there is a lack of understanding about community perceptions and experiences while receiving oxygen therapy for acute conditions. We aimed to understand patient and caregiver perceptions of oxygen therapy in facility-based settings for acute hypoxemic conditions.

Methods

We conducted a scoping review. We searched Medline, Embase, and Web of Science (26 February 2024) for original studies published since 2000 relating to patient or caregiver perceptions and experiences of oxygen for an acute medical need in health facility settings. We used an adapted theoretical framework of acceptability to extract and structure the findings.

Results

Searches returned 10 425 unique records, and 25 articles were included. 20 were from high-income countries, and 18 were qualitative studies. The results showed that patient and caregiver attitudes and feelings about oxygen therapy are strongly influenced by perceived effectiveness, which was almost universally positive. Patients and their caregivers suffer different types of burdens, and these are greater for more advanced respiratory therapies than for simple oxygen therapy. Patient and caregiver understanding of oxygen therapy was low, presenting an opportunity for improved communication. Opportunity costs were highest in caregivers of neonates, who were often separated from their infants for long periods, and out-of-pocket costs were a major consideration in low- and middle-income countries.

Conclusions

In this scoping review, we found distinctions in caregiver and patient burden, and their perspectives of oxygen varied between country income. Intervention coherence - the extent to which the patient and their caregivers understand the treatment - was singled out as the key policy area for improvement. Educational campaigns, like those implemented for previous public health emergencies, could lead to increased public knowledge, and thus acceptability, of oxygen therapy.

Understanding Experiences of Caregivers of Spouses With Dementia During Caregiver Health Care Emergencies

BACKGROUND AND OBJECTIVES

Caregivers of persons with dementia are frequently spouses. Caregiver hospitalization causes disruption to caregiving. The goal of this research was to understand the preparedness and stress trajectory of peri-caregiver hospitalization.

RESEARCH DESIGN AND METHODS

Mixed methods were used. Caregivers of spouses with dementia (n = 1,000) were surveyed to determine their perceived preparedness for their own hospitalization. Journey mapping interviews (n = 18) were used to map caregivers' experiences during 5 phases: (a) their spouse with dementia (SWD)'s dementia diagnosis; (b) their SWD's dementia progression; (c) their own health event; (d) their own hospitalization; and (e) their own return home from the hospital.

RESULTS

Among the 452 (45%) eligible caregiver survey respondents, 75 (17%) had experienced hospitalization in the previous 12 months and 51 (68%) hospitalizations were unexpected. Twenty-three (31%) of hospitalized caregivers indicated they did not have prior plans in place for the care of the SWD. When asked about an unexpected hospitalization in the future, 233 (52%) felt somewhat prepared and 133 (29%) felt not at all prepared. Journey mapping revealed 3 groups of caregivers: Group 1 (n = 7) rated their stress lower during their hospitalization, Group 2 (n = 7) rated their stress highest during their hospitalization, and Group 3 (n = 4) were at a sustained high-stress level.

DISCUSSION AND IMPLICATIONS

Many caregivers are not prepared for their own hospitalization. The stress trajectory through important phases of dementia caregiving and a caregiver's own hospitalization is not universal. Meeting the needs of caregivers' peri-hospitalization should be tailored to the individual caregiver.

Psychological symptoms and health-related quality of life in intubated and non-intubated intensive care survivors: A multicentre, prospective observational cohort study

Objective

To compare long-term psychological symptoms and health-related quality of life (HRQOL) in intubated versus non-intubated ICU survivors.

Design

Prospective, multicentre observational cohort study.

Setting

Four tertiary medical-surgical ICUs in Australia.

Participants

Intubated and non-intubated adult ICU survivors.

Main outcome measures

Primary outcomes: clinically significant psychological symptoms at 3- and 12-month follow-up using Post-Traumatic Stress Syndrome-14 for post-traumatic stress disorder; Depression, Anxiety Stress Scales-21 for depression, anxiety, and stress. Secondary outcomes: HRQOL, using EuroQol-5D-5L questionnaire.

Results

Of the 133 ICU survivors, 54/116 (47 %) had at least one clinically significant psychological symptom (i.e., post-traumatic stress disorder, anxiety, depression, stress) at follow-up. Clinically significant scores for psychological symptoms were observed in 26 (39 %) versus 16 (32 %) at 3-months [odds ratio 1.4, 95 % confidence interval (0.66-3.13), p = 0.38]; 23 (37 %) versus 10 (31 %) at 12-months [odds ratio 1.3, 95 % confidence interval (0.53-3.31), p = 0.57] of intubated versus non-intubated survivors, respectively. Usual activities and mobility were the most commonly affected HRQOL dimension, with >30 % at 3 versus months and >20 % at 12-months of overall survivors reporting ≥ moderate problems. There was no difference between the groups in any of the EQ5D dimensions.

Conclusions

Nearly one-in-two (47 %) of the intubated and non-intubated ICU survivors reported clinically significant psychological symptoms at 3 and 12-month follow-ups. Overall, more than 30 % at 3-months and over 20 % at 12-months of the survivors in both groups had moderate or worse problems with their usual activities and mobility. The presence of psychological symptoms and HRQOL impairments was similar between the groups.

Acceptance and adherence to non-invasive positive pressure ventilation in people with chronic obstructive pulmonary disease: a grounded theory study

Introduction

Non-Invasive Positive Pressure Ventilation (NPPV) is an established treatment for people with Chronic Obstructive Pulmonary Disease (COPD), but it is often improperly used or rejected. The patterns of acceptance and adherence to NPPV, conceiving constraints, and strengths related to its adaptation have not been explored from a qualitative perspective yet.

Objectives

This study aims to qualitatively explore patterns of adaptation to NPPV in people affected by COPD and to identify the core characteristics and the specific adaptive challenges during the adaptation process.

Methods

Forty-two people with moderate or severe COPD were recruited and 336 unstructured interviews were conducted. A Constructivist Grounded Theory was used to gather and analyze data: the transcriptions were mutually gathered in open, selective, and theoretical phases, with open, selective, and theoretical coding, respectively.

Results

The analysis resulted in a non-linear and dynamic process, characterized by three phases: deciding, trying NPPV, and using NPPV. The patterns revealed that positive and negative NPPV experiences, together with beliefs, emotions, stressful mental states, and behaviors result in different acceptance and adherence rates.

Discussions

These findings may be helpful to implement new care strategies to promote acceptance and adherence to NPPV.

Respiratory Care Management of COPD Exacerbations

A COPD exacerbation is characterized by an increase in symptoms such as dyspnea, cough, and sputum production that worsens over a period of 2 weeks. Exacerbations are common. Respiratory therapists and physicians in an acute care setting often treat these patients. Targeted O2 therapy improves outcomes and should be titrated to an SpO2 of 88-92%. Arterial blood gases remain the standard approach to assessing gas exchange in patients with COPD exacerbation. The limitations of arterial blood gas surrogates (pulse oximetry, capnography, transcutaneous monitoring, peripheral venous blood gases) should be appreciated so that they can be used wisely. Inhaled short-acting bronchodilators can be provided by nebulizer (jet or mesh), pressurized metered-dose inhaler (pMDI), pMDI with spacer or valved holding chamber, soft mist inhaler, or dry powder inhaler. The available evidence for the use of heliox for COPD exacerbation is weak. Noninvasive ventilation (NIV) is standard therapy for patients who present with COPD exacerbation and is supported by clinical practice guidelines. Robust high-level evidence with patient important outcomes is lacking for the use of high-flow nasal cannula in patients with COPD exacerbation. Management of auto-PEEP is the priority in mechanically ventilated patients with COPD. This is achieved by reducing airway resistance and decreasing minute ventilation. Trigger asynchrony and cycle asynchrony are addressed to improve patient-ventilator interaction. Patients with COPD should be extubated to NIV. Additional high-level evidence is needed before widespread use of extracorporeal CO2 removal. Care coordination can improve the effectiveness of care for patients with COPD exacerbation. Evidence-based practices improve outcomes in patients with COPD exacerbation.

Identifying themes to inform nursing decisions when caring for patients with acute exacerbation of chronic obstructive pulmonary disease on noninvasive ventilation: A qualitative descriptive study

Prior studies analyzing patient experience with noninvasive ventilation (NIV) found the most impactful interaction that patients remembered was with nurses, however a survey of nurses regarding the management of patients treated with NIV has shown that most nurses felt unprepared to care for these sick patients. Our qualitative descriptive study explored the current nursing experience using NIV as a treatment for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Nine (n = 9) subject matter expert nurses practicing in a variety of clinical settings participated in semi-structured interviews. The COnsolidated criteria for REporting Qualitative research checklist was followed for interview development. Interview transcripts were subsequently analyzed using deductive thematic analysis. Themes identified from the interviews pertained to patient assessment, novice nurses' need for clinical support, team communication, and nursing education. Improving interprofessional team communication and collaboration skills, and implementing guidelines for NIV utilization were specified as essential components of NIV education for nurses. Even though the nursing role in the care of AECOPD NIV patient could be institution dependent, the themes presented in our study are useful in identifying opportunities for NIV nursing education and areas for further research. Patient or Public Contribution: Nurses served as interviewees for this study.
