End-of-life decision-making in respiratory intermediate care units: a European survey

Ventilator Weaning in Prolonged Mechanical Ventilation-A Narrative Review

Patients requiring mechanical ventilation (MV) beyond 21 days, usually referred to as prolonged MV, represent a unique group with significant medical needs and a generally poor prognosis. Research suggests that approximately 10% of all MV patients will need prolonged ventilatory care, and that number will continue to rise. Although we have extensive knowledge of MV in the acute care setting, less is known about care in the post-ICU setting. More than 50% of patients who were deemed unweanable in the ICU will be liberated from MV in the post-acute setting. Prolonged MV also presents a challenge in care for medically complex, elderly, socioeconomically disadvantaged and marginalized individuals, usually at the end of their life. Patients and their families often rely on ventilator weaning facilities and skilled nursing homes for the continuation of care, but home ventilation is becoming more common. The focus of this review is to discuss recent advances in the weaning strategies in prolonged MV, present their outcomes and provide insight into the complexity of care.

[Non-invasive Mechanical Ventilation in Acute Respiratory Failure. Clinical Practice Guidelines - on behalf of the German Society of Pneumology and Ventilatory Medicine]

The guideline update outlines the advantages as well as the limitations of NIV in the treatment of acute respiratory failure in daily clinical practice and in different indications.Non-invasive ventilation (NIV) has a high value in therapy of hypercapnic acute respiratory failure, as it significantly reduces the length of ICU stay and hospitalization as well as mortality.Patients with cardiopulmonary edema and acute respiratory failure should be treated with continuous positive airway pressure (CPAP) and oxygen in addition to necessary cardiological interventions. This should be done already prehospital and in the emergency department.In case of other forms of acute hypoxaemic respiratory failure with only mild or moderately disturbed gas exchange (PaO2/FiO2 > 150 mmHg) there is no significant advantage or disadvantage compared to high flow nasal oxygen (HFNO). In severe forms of ARDS NIV is associated with high rates of treatment failure and mortality, especially in cases with NIV-failure and delayed intubation.NIV should be used for preoxygenation before intubation. In patients at risk, NIV is recommended to reduce extubation failure. In the weaning process from invasive ventilation NIV essentially reduces the risk of reintubation in hypercapnic patients. NIV is regarded useful within palliative care for reduction of dyspnea and improving quality of life, but here in concurrence to HFNO, which is regarded as more comfortable. Meanwhile NIV is also recommended in prehospital setting, especially in hypercapnic respiratory failure and pulmonary edema.With appropriate monitoring in an intensive care unit NIV can also be successfully applied in pediatric patients with acute respiratory insufficiency.

Patient-Centered Discussions About Disease Progression, Symptom, and Treatment Burden in Chronic Obstructive Pulmonary Disease Could Facilitate the Integration of End-of-Life Discussions in the Disease Trajectory: Patient, Clinician, and Literature Perspectives: A Multimethod Approach

Background: Patients with chronic obstructive pulmonary disease (COPD) seldom discuss preferences for future care/treatments with clinicians. The lack of discussions prevents the delivery of care grounded on patient preferences. Instead, treatments become increasingly burdensome as disease progresses and patients approach the end of life. Objective: Identify current and best practice in initiating and conducting conversations about future and palliative care, by integrating data from multiple sources. Design: Multiphasic study where the findings of a systematic literature review and qualitative interviews were combined and synthesized using a triangulation protocol. Setting/Participants: Thirty-three patients with COPD and 14 clinicians from multiple backgrounds were recruited in the United Kingdom. Results: Clinicians' and patients' poor understanding about palliative care and COPD, difficulties in timing and initiating discussions, and service rationing were the main factors for late discussions. Divergent perspectives between patients and clinicians about palliative care discussions often prevented their start. Instead, early and gradual patient-centered discussions on treatment choices, symptom, and treatment burden were recommended by patients, clinicians, and the literature. Earlier patient-centered discussions may reduce their emotional impact and enable patients to participate fully, while enabling clinicians to provide timely and accurate information on illness progression and appropriate self-management techniques. Conclusion: Current approaches toward palliative care discussions in COPD do not guarantee that patients' preferences are met. Early and gradual patient-centered discussions may enable patients to fully express their care preferences as they evolve over time, while minimizing the impact of symptom and treatment burden.

Morbimortality and Six-Month Survival Among Elderly Patients Treated With Noninvasive Mechanical Ventilation in an Intermediate Care Unit: A Retrospective Evaluation

BACKGROUND

Noninvasive mechanical ventilation (NIMV) has been established as a successful therapeutic option for patients with acute respiratory failure (ARF) with a specific etiology.

OBJECTIVES

This study evaluated the morbimortality of patients with ARF treated with NIMV in a medical intermediate care unit (UCINT) to identify factors associated with higher in-hospital mortality, six-month mortality, and three- and six-month hospital readmission rates.

METHODS

This retrospective cohort study included elderly patients admitted for ARF and treated with NIMV in the UCINT between 2015 and 2019.

RESULTS

In the sample of 102 patients, the median age was 84.2 (±5.5) years, and 57% were women. In total, 28% were on long-term oxygen therapy, and 68% had a do-not-resuscitate order. At admission, the median Charlson comorbidity index and Barthel index of activities of daily living were 7 [6; 8] and 30 [20; 57,5], respectively. The simplified acute physiology score II was 39.1±10.7, and 92% of patients had type 2 ARF. Median days on NIMV and days in UCINT were 10 [6; 16] and 6 [3; 10], respectively. The main conditions requiring UCINT admission for NIMV were heart failure, pneumonia, and exacerbation of the chronic obstructive pulmonary disease. The NIMV failure rate was 7%. At discharge, the average Barthel index was 35 [10; 55]. The in-hospital mortality rate was 23%.

DISCUSSION

 Older age, higher simplified acute physiology score II, higher Charlson comorbidity index, and higher number of days on NIMV were associated with higher in-hospital mortality. Long-term oxygen therapy was associated with higher three-month mortality. A higher Barthel index at the time of hospital discharge was associated with a higher six-month readmission rate.

CONCLUSION

NIMV can be used successfully in elderly patients and less studied ARF etiologies, such as pneumonia.

Spanish COPD Guideline (GesEPOC) Update: Comorbidities, Self-Management and Palliative Care

The current health care models described in GesEPOC indicate the best way to make a correct diagnosis, the categorization of patients, the appropriate selection of the therapeutic strategy and the management and prevention of exacerbations. In addition, COPD involves several aspects that are crucial in an integrated approach to the health care of these patients. The evaluation of comorbidities in COPD patients represents a healthcare challenge. As part of a comprehensive assessment, the presence of comorbidities related to the clinical presentation, to some diagnostic technique or to some COPD-related treatments should be studied. Likewise, interventions on healthy lifestyle habits, adherence to complex treatments, developing skills to recognize the signs and symptoms of exacerbation, knowing what to do to prevent them and treat them within the framework of a self-management plan are also necessary. Finally, palliative care is one of the pillars in the comprehensive treatment of the COPD patient, seeking to prevent or treat the symptoms of a disease, the side effects of treatment, and the physical, psychological and social problems of patients and their caregivers. Therefore, the main objective of this palliative care is not to prolong life expectancy, but to improve its quality. This chapter of GesEPOC 2021 presents an update on the most important comorbidities, self-management strategies, and palliative care in COPD, and includes a recommendation on the use of opioids for the treatment of refractory dyspnea in COPD.

Therapiebegrenzung in der Intensivmedizin

Eine der wesentlichen Aufgaben der Intensivmedizin ist die tägliche Überprüfung der getroffenen diagnostischen oder therapeutischen Maßnahmen nach Sinnhaftigkeit. Ist der Sinn nicht gegeben, so müssen nach unseren ethischen Grundsätzen diese unterlassen bzw. beendet und dem Menschen ein Sterben in Würde ermöglicht werden. Die Entscheidungen am Lebensende unterliegen diversen Einflussfaktoren, sodass die Therapiebegrenzung nationalen Richtlinien folgt. Das ethische Klima hat nicht nur Auswirkungen auf den Patienten und seine Familie, sondern auch Burnout-Rate, Personalzufriedenheit und Personalfluktuation stehen in einem direkten Zusammenhang mit den getroffenen Entscheidungen am Lebensende.

"Addressing Advance Care Planning in Patients with COPD"

Chronic obstructive pulmonary disease (COPD) is a progressive debilitating disease with diminished quality of life after COPD hospital admissions. Due to the nature of the disease, it is important to address patients' goals of care, preferably prior to the development of refractory COPD. Advance Care Planning (ACP) is an all-encompassing term that involves discussing goals with patients. Various review articles on ACP and COPD focus on defining ACP, identifying barriers to addressing ACP, and using interventions to incorporate ACP in practice. There is evidence that ACP improves quality of communication, reduces admissions, and increases quality of life, but often the focus of that research has been on patients with cancer. Many of the articles have suggestions for how to apply ACP to chronic lung disease, but without further research and definitive guidance it may be difficult to obtain funding for programs dedicated to ACP. There are currently no guidelines for addressing ACP in patients with COPD. Research addresses why advance care planning is important, yet there are barriers that patients, families, and healthcare providers encounter, preventing meaningful discussions. Research has also found that utilizing multidisciplinary teams improves care and quality of life, yet research should be dedicated to investigating the effects of advance care planning initiatives on outcomes in patients with COPD, particularly in reducing hospital admissions and improving quality of life. This review seeks to educate providers about end-stage COPD and advance care planning, the evidence demonstrating advance care planning's importance, and the current and future state of research.

Explainable Machine Learning to Predict Successful Weaning Among Patients Requiring Prolonged Mechanical Ventilation: A Retrospective Cohort Study in Central Taiwan

Objective: The number of patients requiring prolonged mechanical ventilation (PMV) is increasing worldwide, but the weaning outcome prediction model in these patients is still lacking. We hence aimed to develop an explainable machine learning (ML) model to predict successful weaning in patients requiring PMV using a real-world dataset. Methods: This retrospective study used the electronic medical records of patients admitted to a 12-bed respiratory care center in central Taiwan between 2013 and 2018. We used three ML models, namely, extreme gradient boosting (XGBoost), random forest (RF), and logistic regression (LR), to establish the prediction model. We further illustrated the feature importance categorized by clinical domains and provided visualized interpretation by using SHapley Additive exPlanations (SHAP) as well as local interpretable model-agnostic explanations (LIME). Results: The dataset contained data of 963 patients requiring PMV, and 56.0% (539/963) of them were successfully weaned from mechanical ventilation. The XGBoost model (area under the curve [AUC]: 0.908; 95% confidence interval [CI] 0.864-0.943) and RF model (AUC: 0.888; 95% CI 0.844-0.934) outperformed the LR model (AUC: 0.762; 95% CI 0.687-0.830) in predicting successful weaning in patients requiring PMV. To give the physician an intuitive understanding of the model, we stratified the feature importance by clinical domains. The cumulative feature importance in the ventilation domain, fluid domain, physiology domain, and laboratory data domain was 0.310, 0.201, 0.265, and 0.182, respectively. We further used the SHAP plot and partial dependence plot to illustrate associations between features and the weaning outcome at the feature level. Moreover, we used LIME plots to illustrate the prediction model at the individual level. Additionally, we addressed the weekly performance of the three ML models and found that the accuracy of XGBoost/RF was ~0.7 between weeks 4 and week 7 and slightly declined to 0.6 on weeks 8 and 9. Conclusion: We used an ML approach, mainly XGBoost, SHAP plot, and LIME plot to establish an explainable weaning prediction ML model in patients requiring PMV. We believe these approaches should largely mitigate the concern of the black-box issue of artificial intelligence, and future studies are warranted for the landing of the proposed model.

Prolonged Weaning: S2k Guideline Published by the German Respiratory Society

Mechanical ventilation (MV) is an essential part of modern intensive care medicine. MV is performed in patients with severe respiratory failure caused by respiratory muscle insufficiency and/or lung parenchymal disease; that is, when other treatments such as medication, oxygen administration, secretion management, continuous positive airway pressure (CPAP), or nasal high-flow therapy have failed. MV is required for maintaining gas exchange and allows more time to curatively treat the underlying cause of respiratory failure. In the majority of ventilated patients, liberation or "weaning" from MV is routine, without the occurrence of any major problems. However, approximately 20% of patients require ongoing MV, despite amelioration of the conditions that precipitated the need for it in the first place. Approximately 40-50% of the time spent on MV is required to liberate the patient from the ventilator, a process called "weaning". In addition to acute respiratory failure, numerous factors can influence the duration and success rate of the weaning process; these include age, comorbidities, and conditions and complications acquired during the ICU stay. According to international consensus, "prolonged weaning" is defined as the weaning process in patients who have failed at least 3 weaning attempts, or require more than 7 days of weaning after the first spontaneous breathing trial (SBT). Given that prolonged weaning is a complex process, an interdisciplinary approach is essential for it to be successful. In specialised weaning centres, approximately 50% of patients with initial weaning failure can be liberated from MV after prolonged weaning. However, the heterogeneity of patients undergoing prolonged weaning precludes the direct comparison of individual centres. Patients with persistent weaning failure either die during the weaning process, or are discharged back to their home or to a long-term care facility with ongoing MV. Urged by the growing importance of prolonged weaning, this Sk2 Guideline was first published in 2014 as an initiative of the German Respiratory Society (DGP), in conjunction with other scientific societies involved in prolonged weaning. The emergence of new research, clinical study findings and registry data, as well as the accumulation of experience in daily practice, have made the revision of this guideline necessary. The following topics are dealt with in the present guideline: Definitions, epidemiology, weaning categories, underlying pathophysiology, prevention of prolonged weaning, treatment strategies in prolonged weaning, the weaning unit, discharge from hospital on MV, and recommendations for end-of-life decisions. Special emphasis was placed on the following themes: (1) A new classification of patient sub-groups in prolonged weaning. (2) Important aspects of pulmonary rehabilitation and neurorehabilitation in prolonged weaning. (3) Infrastructure and process organisation in the care of patients in prolonged weaning based on a continuous treatment concept. (4) Changes in therapeutic goals and communication with relatives. Aspects of paediatric weaning are addressed separately within individual chapters. The main aim of the revised guideline was to summarize both current evidence and expert-based knowledge on the topic of "prolonged weaning", and to use this information as a foundation for formulating recommendations related to "prolonged weaning", not only in acute medicine but also in the field of chronic intensive care medicine. The following professionals served as important addressees for this guideline: intensivists, pulmonary medicine specialists, anaesthesiologists, internists, cardiologists, surgeons, neurologists, paediatricians, geriatricians, palliative care clinicians, rehabilitation physicians, intensive/chronic care nurses, physiotherapists, respiratory therapists, speech therapists, medical service of health insurance, and associated ventilator manufacturers.

Survival and end-of-life aspects among subjects on long-term noninvasive ventilation

Background

The need for noninvasive ventilation (NIV) is commonly considered a predictor of poor survival, but life expectancy may vary depending on the underlying disease. We studied the factors associated with decreased survival and end-of-life characteristics in an unselected population of subjects starting NIV.

Methods

We conducted a retrospective study including 205 subjects initiating NIV from 1/1/2012-31/12/2015 who were followed up until 31/12/2017.

Results

The median survival time was shorter in subjects needing help with activities of daily living than in independent subjects (hazard ratio (HR) for death 1.7, 95% CI 1.2–2.6, P = 0.008) and was also shorter in subjects on long-term oxygen therapy (LTOT) than in those not on LTOT (HR for death 2.8, 95% CI 1.9–4.3, P < 0.001). There was marked difference in survival according to the disease necessitating NIV, and subjects with amyotrophic lateral sclerosis or interstitial lung disease seemed to have the shortest survival. The two most common diseases resulting in the need for NIV were chronic obstructive pulmonary disease (COPD) and obesity hypoventilation syndrome (OHS). The median survival time was 4.4 years in COPD subjects, but the median survival time was not reached in subjects with OHS (HR for death COPD vs. OHS: 3.2, 95% CI 1.9–5.5, P < 0.001). Most of the deceased subjects (55.6%) died in the hospital, while only 20.0% died at home. The last hospitalization admission leading to death occurred through the emergency room in 44.4% of the subjects.

Conclusions

Survival among subjects starting NIV in this real-life study varied greatly depending on the disease and degree of functional impairment. Subjects frequently died in the hospital after admission through the emergency department. A comprehensive treatment approach with timely advance care planning is therefore needed, especially for those needing help with activities of daily living and those with both NIV and LTOT.

Ventilator Support and Oxygen Therapy in Palliative and End-of-Life Care in the Elderly

Elderly patients suffering from chronic cardio-pulmonary diseases commonly experience acute respiratory failure. As in younger patients, a well-known therapeutic approach of noninvasive mechanical ventilation is able to prevent orotracheal intubation in a large number of severe scenarios in elderly patients. In addition, this type of ventilation is frequently applied in elderly patients who refuse intubation for invasive mechanical ventilation. The rate of failure of noninvasive ventilation may be reduced by means of the integration of new technological devices (i.e., high-flow nasal cannula, extracorporeal CO₂ removal, cough assistance and high-frequency chest wall oscillation, and fiberoptic bronchoscopy). Ethical issues with end-of-life decisions and the choice of the environment are not clearly defined in the treatment of elderly with acute respiratory insufficiency.

Patients with limitation or withdrawal of life supporting care admitted in a medico-surgical intermediate care unit: Prevalence, description and outcome over a six-month period

Purpose

There have been few studies on the limitation of Life Supporting Care (LSC) and Withdrawal of LSC in Intermediate Care Units (IMCUs). We report the prevalence of LSC limited patients in a medico-surgical IMCU over a six-month period, examining the description, outcomes, and patterns of LSC Limitations and Withdrawal of LSC.

Methods

Single center, retrospective observational study in an IMCU of a 500-bed general hospital.

Results

Our study of 404 patients, reported 79 (19.5%, 95%CI: [16.0–23.7]%) being admitted with LSC limitations in the IMCU. This group of LSC limited patients presented with higher chronic and acute severity scores. The most common admission diagnosis of LSC limited patients was acute respiratory failure (51%). Non-invasive ventilation (NIV) was frequently used within this population (39%). Hospital mortality for LSC limited patients was high (53%) and associated with age (OR = 1.07, 95%CI: [1.01–1.13)]), SOFA score (OR 1.29, 95%CI: [1.01–1.64]), and hypoxemic respiratory failure (OR 7.2, 95%CI: [1.27–40.9]). Withdrawal of LSC occurred in 19.5% of cases, often accompanied with terminal sedation with or without NIV removal (43.8%).

Conclusions

Patients with limitation of LSC are frequently admitted into IMCU. Hospital mortality rate was high and associated with age, acute organ failures, and hypoxemic respiratory failure. Life support withdrawal includes palliative sedation with or without NIV discontinuation.

Treatment decisions in end-stage COPD: who decides how? A cross-sectional survey of different medical specialties

Introduction

End-stage chronic obstructive pulmonary disease (COPD) patients with acute respiratory failure are often treated by representatives from different medical specialties. This study investigates if the choice of treatment is influenced by the medical specialty.

Methods

An online cross-sectional survey among four Austrian medical societies was performed, accompanied by a case vignette of a geriatric end-stage COPD patient with acute respiratory failure. Respondents had to choose between noninvasive ventilation (NIV), a conservative treatment attempt (without NIV) and a palliative approach. Ethical considerations and their impact on decision making were also assessed.

Results

Responses of 162 physicians (67 from intensive care units (ICUs), 51 from pulmonology or internal departments and 44 from geriatric or palliative care) were included. The decision for NIV (instead of a conservative or palliative approach) was associated with working in an ICU (OR 14.9, 95% CI 1.87-118.8) and in a pulmonology or internal department (OR 9.4, 95% CI 1.14-78.42) compared with working in geriatric or palliative care (Model 1). The decision for palliative care was negatively associated with working in a pulmonology or internal department (OR 0.16, 95% CI 0.05-0.47) and (nonsignificantly) in an ICU (OR 0.41, 95% CI 0.15-1.12) (Model 2).

Conclusions

Department association was shown to be an independent predictor for treatment decisions in end-stage COPD with acute respiratory failure. Further research on these differences and influential factors is necessary.

Non-invasive ventilation in palliative care: a systematic review

INTRODUCTION

An ageing population and steady increase in the rates of neoplasms and chronic degenerative diseases poses a challenge for societies and their healthcare systems. Because of the recent and continued advances in therapies, such as the development and widespread use of non-invasive ventilation (NIV), survival rates have increased for these pathologies. For patients with end-stage chronic respiratory diseases, the use of NIV following the onset of acute or severe chronic respiratory failure is a valid option when intubation has been excluded.

EVIDENCE ACQUISITION

The following electronic databases were searched from their inception to January 2000 to December 2017: MEDLINE, EMBASE, CINHAIL, CENTRAL (Cochrane Central register of Controlled Trials), DARE (Database of Abstracts of Reviews of Effectiveness), the Cochrane Database of Systematic Reviews, ACP Journal Club database.

EVIDENCE SYNTHESIS

The available evidence strongly supports the use of NIV in patients presenting with an exacerbation of chronic obstructive pulmonary disease, as well end-stage neuromuscular disease. Few studies support the use of NIV in end-stage interstitial lung disease and in morbid obesity patients. In patients with cancer has been recommend offering NIV as palliative care to improve dyspnea.

CONCLUSIONS

The decision regarding the treatment should be made by the patient, ideally before reaching the terminal stage and after having a frank dialogue with healthcare professionals and family members.

Benefits of non-invasive ventilation in acute hypercapnic respiratory failure

Non-invasive ventilation (NIV) with bilevel positive airway pressure is a non-invasive technique, which refers to the provision of ventilatory support through the patient's upper airway using a mask or similar device. This technique is successful in correcting hypoventilation. It has become widely accepted as the standard treatment for patients with hypercapnic respiratory failure (HRF). Since the 1980s, NIV has been used in intensive care units and, after initial anecdotal reports and larger series, a number of randomized trials have been conducted. Data from these trials have shown that NIV is a valuable treatment for HRF. This review aims to explore the principal areas in which NIV can be useful, focusing particularly on patients with acute HRF (AHRF). We will update the evidence base with the goal of supporting clinical practice. We provide a practical description of the main indications for NIV in AHRF and identify the group of patients with hypercapnic failure who will benefit most from the application of NIV.

Noninvasive ventilation in acute respiratory failure: which recipe for success?

Noninvasive positive-pressure ventilation (NPPV) to treat acute respiratory failure has expanded tremendously over the world in terms of the spectrum of diseases that can be successfully managed, the locations of its application and achievable goals.

The turning point for the successful expansion of NPPV is its ability to achieve the same physiological effects as invasive mechanical ventilation with the avoidance of the life-threatening risks correlated with the use of an artificial airway.

Cardiorespiratory arrest, extreme psychomotor agitation, severe haemodynamic instability, nonhypercapnic coma and multiple organ failure are absolute contraindications for NPPV. Moreover, pitfalls of NPPV reduce its rate of success; consistently, a clear plan of what to do in case of NPPV failure should be considered, especially for patients managed in unprotected setting. NPPV failure is likely to be reduced by the application of integrated therapeutic tools in selected patients handled by expert teams.

In conclusion, NPPV has to be considered as a rational art and not just as an application of science, which requires the ability of clinicians to both choose case-by-case the best “ingredients” for a “successful recipe” (i.e.patient selection, interface, ventilator, interface,etc.) and to avoid a delayed intubation if the ventilation attempt fails.

Positive airway pressure devices for the management of breathlessness

PURPOSE OF REVIEW

Breathlessness is a common symptom in many chronic diseases and may be refractory to pharmacotherapy. In this review, we discuss the pathophysiology of breathlessness and the role of positive airway pressure (PAP) devices to ameliorate it.

RECENT FINDINGS

Breathlessness is directly related to neural respiratory drive, which can be modified by addressing the imbalance between respiratory muscle load and capacity. Noninvasive PAP devices have been applied to patients limited by exertional breathless and, as the disease progresses, breathlessness at rest. The application of PAP is focussed on addressing the imbalance in load and capacity, aiming to reduce neural respiratory drive and breathlessness. Indeed, noninvasive bi-level PAP devices have been employed to enhance exercise capacity by enhancing pulmonary mechanics and reduce neural drive in chronic obstructive pulmonary disease (COPD) patients, and reduce breathlessness for patients with progressive neuromuscular disease (NMD) by enhancing respiratory muscle capacity. Novel continuous PAP devices have been used to maintain central airways patency in patients with excessive dynamic airway collapse (EDAC) and target expiratory flow limitation in severe COPD.

SUMMARY

PAP devices can reduce exertional and resting breathlessness by reducing the load on the system and enhancing capacity to reduce neural respiratory drive.

The patient needing prolonged mechanical ventilation: a narrative review

BACKGROUND

Progress in management has improved hospital mortality of patients admitted to the intensive care units, but also the prevalence of those patients needing weaning from prolonged mechanical ventilation, and of ventilator assisted individuals. The result is a number of difficult clinical and organizational problems for patients, caregivers and health services, as well as high human and financial resources consumption, despite poor long-term outcomes. An effort should be made to improve the management of these patients. This narrative review summarizes the main concepts in this field.

MAIN BODY

There is great variability in terminology and definitions of prolonged mechanical ventilation.There have been several recent developments in the field of prolonged weaning: ventilatory strategies, use of protocols, early mobilisation and physiotherapy, specialised weaning units.There are few published data on discharge home rates, need of home mechanical ventilation, or long-term survival of these patients.Whether artificial nutritional support improves the outcome for these chronic critically ill patients, is unclear and controversial how these data are reported on the optimal time of initiation of parenteral vs enteral nutrition.There is no consensus on time of tracheostomy or decannulation. Despite several individualized, non-comparative and non-validated decannulation protocols exist, universally accepted protocols are lacking as well as randomised controlled trials on this critical issue. End of life decisions should result from appropriate communication among professionals, patients and surrogates and national legislations should give clear indications.

CONCLUSION

Present medical training of clinicians and locations like traditional intensive care units do not appear enough to face the dramatic problems posed by these patients. The solutions cannot be reserved to professionals but must involve also families and all other stakeholders. Large multicentric, multinational studies on several aspects of management are needed.

Update: non-invasive ventilation in chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) remains a common cause of morbidity and mortality worldwide. Patients with COPD and respiratory failure, whether acute or chronic have a poorer prognosis than patients without respiratory failure. Non-invasive ventilation (NIV) has been shown to be a useful tool in both the acute hospital and chronic home care setting. NIV has been well established as the gold standard therapy for acute decompensated respiratory failure complicating an acute exacerbation of COPD with reduced mortality and intubation rates compared to standard therapy. However, NIV has been increasingly used in other clinical situations such as for weaning from invasive ventilation and to palliate symptoms in patients not suitable for invasive ventilation. The equivocal evidence for the use of NIV in chronic hypercapnic respiratory failure complicating COPD has recently been challenged with data now supporting a role for therapy in selected subgroups of patients. Finally the review will discuss the emerging role of high flow humidified therapy to support or replace NIV in certain clinical situation.

Transition from in-hospital ventilation to home ventilation: process description and quality indicators

The current demographic development of our society results in an increasing number of elderly patients with chronic diseases being treated in the intensive care unit. A possible long-term consequence of such a treatment is that patients remain dependent on certain invasive organ support systems, such as long-term ventilator dependency. The main goal of this project is to define the transition process between in-hospital and out of hospital (ambulatory) ventilator support. A further goal is to identify evidence-based quality indicators to help define and describe this process.

This project describes an ideal sequence of processes (process chain), based on the current evidence from the literature. Besides the process chain, key data and quality indicators were described in detail. Due to the limited project timeline, these indicators were not extensively tested in the clinical environment.

The results of this project may serve as a solid basis for proof of feasibility and proof of concept investigations, optimize the transition process of ventilator-dependent patients from a clinical to an ambulatory setting, as well as reduce the rate of emergency re-admissions.

Attitudes and preferences of home mechanical ventilation users from four European countries: an ERS/ELF survey

Home mechanical ventilation is increasingly used by people with chronic respiratory failure. However, there are few reports on attitudes towards treatment.

A web-based survey in eight languages was disseminated across 11 European countries to evaluate the perception of home mechanical ventilation provision in ventilator-assisted individuals and caregivers.

Out of 787 responders from 11 European countries, 687 were patients and 100 were caregivers. 95% of patients and 94% of caregivers were from only 4 countries (Germany, the Netherlands, Italy, Spain). The majority of respondents were male and aged 46–65 years. Obstructive lung diseases were proportionally more represented among respondent patients (46%), and neuromuscular diseases (65%) were more represented among patients of respondent caregivers. About 20% of respondent patients and caregivers were not sure of the modality of ventilation. Different interfaces were used, with a minority of respondents in all countries using invasive home mechanical ventilation by tracheostomy.

These results may be useful for healthcare providers and policy makers to improve the quality of patients' daily lives.

Challenges on non-invasive ventilation to treat acute respiratory failure in the elderly

Acute respiratory failure is a frequent complication in elderly patients especially if suffering from chronic cardio-pulmonary diseases. Non-invasive mechanical ventilation constitutes a successful therapeutic tool in the elderly as, like in younger patients, it is able to prevent endotracheal intubation in a wide range of acute conditions; moreover, this ventilator technique is largely applied in the elderly in whom invasive mechanical ventilation is considered not appropriated. Furthermore, the integration of new technological devices, ethical issues and environment of treatment are still largely debated in the treatment of acute respiratory failure in the elderly.

This review aims at reporting and critically analyzing the peculiarities in the management of acute respiratory failure in elderly people, the role of noninvasive mechanical ventilation, the potential advantages of applying alternative or integrated therapeutic tools (i.e. high-flow nasal cannula oxygen therapy, non-invasive and invasive cough assist devices and low-flow carbon-dioxide extracorporeal systems), drawbacks in physician’s communication and “end of life” decisions. As several areas of this topic are not supported by evidence-based data, this report takes in account also “real-life” data as well as author’s experience.

The choice of the setting and of the timing of non-invasive mechanical ventilation in elderly people with advanced cardiopulmonary disease should be carefully evaluated together with the chance of using integrated or alternative supportive devices. Last but not least, economic and ethical issues may often challenges the behavior of the physicians towards elderly people who are hospitalized for acute respiratory failure at the end stage of their cardiopulmonary and neoplastic diseases.

What does end stage in neuromuscular diseases mean? Key approach-based transitions

PURPOSE OF REVIEW

To revise the definition of end stage in the setting of neuromuscular disease (NMD), to understand the implications for the patient, family and healthcare team, and to address the obstacles involved in the lack of definition.

RECENT FINDINGS

Unlike several conditions such as cancer, kidney or liver disease, the literature reveals no clear definition or categorization for NMD. Many articles mention end stage without defining it. Many years ago an expert consensus panel defined it based on functional criteria (forced vital capacity values and hypercapnic events). Only for amyotrophic lateral sclerosis/motoneurone disease has a wider criteria been proposed. As a consequence, the management of this heterogeneous group of disorders is often fragmented compared with the well organized palliative care program for cancer patients.

SUMMARY

Better end-stage NMD definitions should help to identify the goals of care, but a broad range in time and intensity of deterioration make a valid definition difficult for end-stage NMD. Respiratory care, life-prolonging therapies, and structured care planning should be seen as complementary rather than dichotomous. This article emphasized the relevance of an integrated approach through the whole trajectories of NMD patients considering key transitions.

Considerations and values in decision making regarding mechanical ventilation for older patients with severe to very severe COPD

Background

The different considerations involved in decisions regarding whether or not to initiate mechanical ventilation for patients with severe chronic obstructive pulmonary disease (COPD) are challenging for health professionals.

Aim

To investigate the considerations and values that influences decision-making regarding mechanical ventilation in older patients (≥65-years-old) with severe to very severe COPD. Furthermore, it aims to elucidate how physicians involve their patient in decision-making process.

Participants and setting

Seven intensive care physicians and seven physicians working in the respiratory units at two university hospitals and two district hospitals in Norway.

Methods

This study had a qualitative design consisting of focus group interviews with 14 physicians. The data was analysed according to the interpretative contexts: self-understanding, critical common-sense understanding and theoretical understanding.

Results

Decisions regarding mechanical ventilation were mainly based on the physicians' own experiences, their perceptions of the patients' situation, and biomedical data. The patients were not involved in the decision-making and such decisions were only occasionally made in a multi-professional context.

Conclusion

To decide whether older patients with severe COPD should be treated with mechanical ventilation is both medically and ethically challenging for physicians. Decision making in this context seems to be mainly driven by a paternalistic attitude, since the physicians interviewed in our study, in general, make such decisions without involving either the patient, their next of kin or the nurses. There is a need for broader cooperation between health professional and for the involvement of patients in the decision-making process regarding mechanical ventilation in cases of late stage COPD.

End-of-Life Discussion, Patient Understanding and Determinants of Preferences in Very Severe COPD Patients: A Multicentric Study

Discussion about patients' end-of-life (E-o-L) preferences should be part of the routine practice. Using a semi-structured interview with a scenario-based decision, we performed a prospective multicentre study to elicit the patients' E-o-L preferences in very severe chronic obstructive pulmonary disease (COPD). We also checked their ability to retain this information and the respect of their decisions when they die. Forty-three out of ninety-one of the eligible patients completed the study. The choice of E-o-L practice was equally distributed among the three proposed options: endotracheal intubation (ETI), 'ceiling' non-invasive ventilation (NIV), and palliation of symptoms with oxygen and morphine. NIV and ETI were more frequently chosen by patients who already experienced them. ETI preference was also associated with the use of anti-depressant drugs and a low educational level, while a higher educational level and a previous discussion with a pneumologist significantly correlated with the preference for oxygen and morphine. Less than 50% of the patients retained a full comprehension of the options at 24 hours. About half of the patients who died in the follow-up period were not treated according to their wishes. In conclusion, in end-stage COPD more efforts are needed to improve communication, patients' knowledge of the disease and E-o-L practice.

Longitudinal change in quality of life following hospitalisation for acute exacerbations of COPD

Background

Current guidelines for management of patients hospitalised with acute exacerbations of chronic obstructive pulmonary disease (COPD) recommend that clinical decisions, including escalation to assisted ventilation, be informed by an estimate of the patients’ likely postdischarge quality of life. There is little evidence to inform predictions of outcome in terms of quality of life, psychological well-being and functional status. Undue nihilism might lead to denial of potentially life-saving therapy, while undue optimism might prolong suffering when alternative palliation would be more appropriate. This study aimed to detail longitudinal changes in quality of life following hospitalisation for acute exacerbations of COPD.

Methods

We prospectively recruited two cohorts (exacerbations requiring assisted ventilation during admission and exacerbations not ventilated). Admission clinical data, and mortality and readmission details were collected. Quality of life, psychological well-being and functional status were formally assessed over the subsequent 12 months. Time-adjusted mean change in quality of life was examined.

Results

183 patients (82 ventilated; 101 not ventilated) were recruited. On average, overall quality of life improved by a clinically important amount in those not ventilated and did not decline in ventilated patients. Both groups showed clinically important improvements in respiratory symptoms and an individual's sense of control over their condition, despite the tendency for functional status to decline.

Conclusions

On average, postdischarge quality of life improved in non-ventilated and did not decline in ventilated patients. Certain quality of life domains (ie, symptoms and mastery) improved significantly. Better understanding of longitudinal change in postdischarge quality of life should help to inform decision-making.

Aggressiveness of intensive care use among patients with lung cancer in the Surveillance, Epidemiology, and End Results-Medicare registry

BACKGROUND

Approximately 65% of elderly patients with lung cancer who are admitted to the ICU will die within 6 months. Efforts to improve end-of-life care for this population must first understand the patient factors that underlie admission to the ICU.

METHODS

We performed a retrospective cohort study examining all fee-for-service inpatient claims in the Surveillance, Epidemiology, and End Results (SEER)-Medicare registry for elderly patients (aged > 65 years) who had received a diagnosis of lung cancer between 1992 and 2005 and who were hospitalized for reasons other than resection of their lung cancer. We calculated yearly rates of ICU admission per 1,000 hospitalizations via room and board codes or International Classification of Diseases, Ninth Revision, Clinical Modification and diagnosis-related group codes for mechanical ventilation, stratified the rates by receipt of mechanical ventilation and ICU type (medical/surgical/cardiac vs intermediate), and compared these rates over time.

RESULTS

A total of 175,756 patients with lung cancer in SEER were hospitalized for a reason other than surgical resection of their tumor during the study period, 49,373 (28%) of whom had at least one ICU stay. The rate of ICU admissions per 1,000 hospitalizations increased over the study period from 140.7 in 1992 to 201.7 in 2005 (P < .001). The majority of the increase in ICU admissions (per 1,000 hospitalizations) between 1992 and 2005 occurred among patients who were not mechanically ventilated (118.2 to 173.3, P < .001) and among those who were in intermediate ICUs (20.0 to 61.9, P < .001), but increased only moderately in medical/surgical/cardiac units (120.7 to 139.9, P < .001).

CONCLUSIONS

ICU admission for patients with lung cancer increased over time, mostly among patients without mechanical ventilation who were largely cared for in intermediate ICUs.

Non-invasive ventilation for very old patients with limitations to respiratory care in half-open geriatric ward: experience on a consecutive cohort of patients

INTRODUCTION

A leading role for non-invasive ventilation (NIV), as comfort treatment or palliative care, is actually recognized for very old patients suffering from ARF. NIV was frequently used in both ICU and respiratory ICU (RICUs) for very old patients and it is associated with a reduced rate of endotracheal intubations and mortality. This study aims to evaluate the effects of NIV, performed in a setting of half-open geriatric ward with family support, in a cohort of very old patients with ARF and DNI decision.

METHODS

A consecutive cohort of 20 very old patients with DNI decision was admitted in our 26-bed geriatric ward during a 6 months' period. DNI decision was obtained in emergency room with an intensive care physician supported by a psychologist. Pressure support ventilation was the first choice of NIV. NIV has been performed by three adequately trained geriatricians, with one of them experienced in ICU, and in close collaboration with intensive care physicians. Arterial blood gases, to assess the response to ventilation, were obtained after 1, 6 and 12 h. NIV settings were modified according to arterial blood gas analyses or respiratory fatigue, if needed.

RESULTS

Therefore, 75% of patients were discharged home and 12 out of 20 patients had home respiratory support. PaO2/FiO2 ratio and pH increased while PaCO2 decreased during the 12 h of NIV with statistical significance. At the admission, alive patients had PaCO2 significantly lower than dead patients. After 12 h, alive patients had a better pH than dead patients. Dead patients experienced more complication than survivors.

CONCLUSION

Very old DNI patients with ARF could be treated with NIV in half-open geriatric ward with trained physicians and nurses. The presence of family members may improve patients' comfort and reduce anxiety level even at the end of life. Further studies are needed to address the effective role of NIV in very old patients with DNI decisions.

The use of non-invasive ventilation in very old patients with hypercapnic acute respiratory failure because of COPD exacerbation

AIMS

We prospectively enrolled 207 patients (121 were 75 or older and 86 younger than 75) who were admitted to three Respiratory Monitoring Units. The primary outcomes were intubation and mortality rates; the secondary outcomes were changes in arterial blood gases analysis, non-invasive ventilation (NIV) duration and length of hospital stay.

RESULTS

Hospital mortality was similar in the two groups, as were intubation rates. The proportion who died in the very old patient group was 19.8% (24/121) vs. 10.4% (9/86) in the younger group. Intubation rate was 10.7% (13/121) in the very old patient group and 11.6% (10/86) in the younger group. The presence of comorbidities, the severity of illness (SAPS II), the level of consciousness, NIV failure (intubation), absolute value of pH prior to NIV, as well as the changes in pH and paCO2 and PaO2 /FiO2 after 2 h of NIV, were the variables associated with higher mortality. Very old patients had significantly higher NIV duration than younger patients (69.0 ± 47.0 vs. 57.0 ± 27.0 h) (p ≤ 0.03) and hospital stays (11.6 ± 3.8 vs. 8.4 ± 1.4) (p ≤ 0.02).

CONCLUSIONS

The use of NIV in very old patients was effective in many cases. Endotracheal intubation after NIV failure was not efficacious in either group.

End-of-life care in COPD: a survey carried out with Portuguese pulmonologists

INTRODUCTION

End-of-life (EoL) care is a major component in the management of patients with advanced COPD. Patient-physician communication is essential in this process.

AIM

To evaluate the practice of Portuguese Pulmonologists in EoL communication and palliative care in COPD.

METHODS

An on-line survey was sent to physicians affiliated to the Portuguese Pneumology Society.

RESULTS

We obtained 136 answers from 464 eligible participants (29.3%). About half of the physicians reported that they have rarely introduced EoL discussions with their COPD patients (48.5%). Most had never/rarely suggested decision-making on the use of invasive mechanical ventilation (68.4%). Discussions were described as occurring mostly during/after a major exacerbation (53.7%). Only 37.5% of participants reported treating dyspnoea with opioids frequently/always. Only 9.6% stated that they never/rarely treated anxiety/depression. Most participants perceive the discussion of EoL issues as being difficult/very difficult (89.0%). The reasons most frequently given were feeling that patients were not prepared for this discussion (70.0%), fear of taking away a patient's hope (58.0%) and lack of training (51.0%).

CONCLUSION

Patient and medical staff EoL communication in COPD is still not good enough. Training in this area and the creation of formal protocols to initiate EoL have been identified as major factors for improvement.

Comparison of timing and decision-makers of do-not-resuscitate orders between thoracic cancer and non-cancer respiratory disease patients dying in a Japanese acute care hospital

PURPOSE

The aim of the study was to compare timing and decision-makers of do-not-resuscitate (DNR) orders between patients with end-stage thoracic cancer and non-cancer respiratory diseases in a Japanese acute care hospital.

METHODS

This study retrospectively reviewed the medical records of patients who died between January 2008 and March 2013 in the Department of Respiratory Medicine of Osaka Police Hospital, a teaching and acute care hospital. We compared the decision-making process, especially timing and decision-maker, of DNR orders between patients with thoracic cancer and patients with non-cancer respiratory diseases.

RESULTS

There were 300 cancer patients and 147 non-cancer patients. Cancer patients were significantly younger, were hospitalized more frequently and for longer, were more likely to have a DNR order placed earlier and decided in advance of last admission, and were more likely to have normal cognitive function at the time of the DNR order than non-cancer patients. Spouses of cancer patients were more likely to participate in DNR discussion. Only approximately 6 % of patients participated in DNR discussion in both groups. Cancer patients less frequently received aggressive treatment at the end of life (EOL) and were more likely to die in general wards than in intensive care units.

CONCLUSIONS

Our study found that most Japanese patients, with or without cancer, who died in an acute care respiratory department, were not included in DNR discussions and that familial surrogates usually made the DNR decision at the EOL.

Lung cancer stigma, anxiety, depression and symptom severity

OBJECTIVES

Compared to other cancers, lung cancer patients report the highest levels of psychological distress and stigma. Few studies have examined the relationship between lung cancer stigma (LCS) and symptom burden. This study was designed to investigate the relationship between LCS, anxiety, depression and physical symptom severity.

METHODS

This study employed a cross-sectional, correlational design to recruit patients online from lung cancer websites. LCS, anxiety, depression and physical symptoms were measured by patient self-report using validated scales via the Internet. Hierarchical multiple regression was performed to investigate the individual contributions of LCS, anxiety and depression to symptom severity.

RESULTS

Patients had a mean age of 57 years; 93% were Caucasian, 79% were current or former smokers, and 74% were female. There were strong positive relationships between LCS and anxiety (r = 0.413, p < 0.001), depression (r = 0.559, p < 0.001) and total lung cancer symptom severity (r = 0.483, p < 0.001). Although its contribution was small, LCS provided a unique and significant explanation of the variance in symptom severity beyond that of age, anxiety and depression, by 1.3% (p < 0.05).

CONCLUSIONS

Because LCS is associated with psychosocial and physical health outcomes, research is needed to develop interventions to assist patients to manage LCS and to enhance their ability to communicate effectively with clinicians.

Referral to palliative care in COPD and other chronic diseases: a population-based study

AIM

To describe how patients with COPD, heart failure, dementia and cancer differ in frequency and timing of referral to palliative care services.

METHODS

We performed a population-based study with the Sentinel Network of General Practitioners in Belgium. Of 2405 registered deaths respectively 5%, 4% and 28% were identified as from COPD, heart failure or cancer and 14% were diagnosed with severe dementia. GPs reported use and timing of palliative care services and treatment goals in the final three months of life.

RESULTS

Patients with COPD (20%) were less likely than those with heart failure (34%), severe dementia (37%) or cancer (60%) to be referred to palliative care services (p < 0.001). The median days between referral and death was respectively 10, 12, 14 and 20. Patients with COPD who were not referred more often received treatment with a curative or life-prolonging goal and less often with a palliative or comfort goal than did the other patients who were not referred.

CONCLUSION

Patients with COPD are underserved in terms of palliative care compared to those with other chronic life-limiting diseases. Awareness of palliative care as an option for patients with COPD needs to increase in palliative care services, physicians and the general public.

Chronic Obstructive Pulmonary Disease: official diagnosis and treatment guidelines of the Czech Pneumological and Phthisiological Society; a novel phenotypic approach to COPD with patient-oriented care

BACKGROUND

COPD is a global concern. Currently, several sets of guidelines, statements and strategies to managing COPD exist around the world.

METHODS

The Czech Pneumological and Phthisiological Society (CPPS) has commissioned an Expert group to draft recommended guidelines for the management of stable COPD. Subsequent revisions were further discussed at the National Consensus Conference (NCC). Reviewers' comments contributed to the establishment of the document's final version.

DIAGNOSIS

The hallmark of the novel approach to COPD is the integrated evaluation of the patient's lung functions, symptoms, exacerbations and identifications of clinical phenotype(s). The CPPS defines 6 clinically relevant phenotypes: frequent exacerbator, COPD-asthma overlap, COPD-bronchiectasis overlap, emphysematic phenotype, bronchitic phenotype and pulmonary cachexia phenotype.

TREATMENT

Treatment recommendations can be divided into four steps. 1(st) step = Risk exposure elimination: reduction of smoking and environmental tobacco smoke (ETS), decrease of home and occupational exposure risks. 2(nd) step = Standard treatment: inhaled bronchodilators, regular physical activity, pulmonary rehabilitation, education, inhalation training, comorbidity treatment, vaccination. 3(rd) step = Phenotype-specific therapy: PDE4i, ICS+LABA, LVRS, BVR, AAT augmentation, physiotherapy, mucolytic, ABT. 4(th) step = Care for respiratory insufficiency and terminal COPD: LTOT, lung transplantation, high intensity-NIV and palliative care.

CONCLUSION

Optimal treatment of COPD patients requires an individualised, multidisciplinary approach to the patient's symptoms, clinical phenotypes, needs and wishes. The new Czech COPD guideline reflects and covers these requirements.

Noninvasive mechanical ventilation in patients having declined tracheal intubation

PURPOSE

Noninvasive ventilation (NIV) is a treatment option in patients with acute respiratory failure who are good candidates for intensive care but have declined tracheal intubation. The aim of our study was to report outcomes after NIV in patients with a do-not-intubate (DNI) order.

METHODS

Prospective observational cohort study in all patients who received NIV for acute respiratory failure in 54 ICUs in France and Belgium, in 2010/2011.

RESULTS

Goals of care, comfort, and vital status were assessed daily. On day 90, a telephone interview with patients and relatives recorded health-related quality of life (HRQOL), posttraumatic stress disorder-related symptoms, and symptoms of anxiety and depression. Post-ICU burden was compared between DNI patients and patients receiving NIV with no treatment-limitation decisions (TLD). Of 780 NIV patients, 574 received NIV with no TLD, and 134 had DNI orders. Hospital mortality was 44 % in DNI patients and 12 % in the no-TLD group. Mortality in the DNI group was lowest in COPD patients compared to other patients in the DNI group (34 vs. 51 %, P = 0.01). In the DNI group, HRQOL showed no significant decline on day 90 compared to baseline; day-90 data of patients and relatives did not differ from those in the no-TLD group.

CONCLUSIONS

Do-not-intubate status was present among one-fifth of ICU patients who received NIV. DNI patients who were alive on day 90 experienced no decrease in HRQOL compared to baseline. The prevalences of anxiety, depression, and PTSD-related symptoms in these patients and their relatives were similar to those seen after NIV was used as part of full-code management (clinicaltrial.govNCT01449331).

Good end-of-life care: perspectives of middle-aged and older Singaporeans

CONTEXT

Understanding preferences for end-of-life care is important for planning and improving services that provide such care. However, little is known about the perspective of Singaporeans regarding good end-of-life care.

OBJECTIVES

To identify the key components of good end-of-life care as perceived by middle-aged and older Singaporeans (≥50 years).

METHODS

Nine focus groups were conducted with a total of 63 participants. Preferences regarding end-of-life care were discussed. Thematic analysis was conducted on the transcribed results of the focus groups.

RESULTS

Eight components of good end-of-life care were identified: 1) have physical comfort at the end of life, 2) avoid inappropriate prolongation of the dying process, 3) maintain sensitivity toward religious and spiritual beliefs, 4) avoid burden on the family, 5) avoid expensive care, 6) be cared for by a trustworthy doctor, 7) maintain control over care decisions, and 8) achieve a sense of completion.

CONCLUSION

Eight components of good end-of-life care involving the person, family, and health services were identified among middle-aged and older Singaporeans. A focus on better management of pain, training of caregivers and doctors, shared decision making, and availability of affordable care may improve care at the end of life.

Practical management problems of stable chronic obstructive pulmonary disease in the elderly

PURPOSE OF REVIEW

Chronic obstructive pulmonary disease (COPD) is one of the most prevalent and increasing health problems in the elderly on a worldwide scale. The management of COPD in older patients presents practical diagnostic and treatment issues, which are reviewed with reference to the stable stage of the disease.

RECENT FINDINGS

In the diagnostic approach of COPD in the elderly the use of spirometry is recommended, but both patient conditions (such as inability to correctly perform it due to fatigue, lack of coordination, and cognitive impairment) and metrics characteristics should be taken into account for the test performance. It has been demonstrated in population studies that the use of the fixed ratio determines a substantial overdiagnosis of COPD in the oldest patients. Other parameters have been suggested [such as the evaluation of Lower Limit of Normality (LLN) for the FEV1/FVC ratio], which may be useful to guide the diagnosis. Several nonpharmacologic - such as smoking cessation, vaccination, physical activity, and pulmonary rehabilitation, nutrition, and eventually invasive ventilation - and pharmacologic interventions have been shown to improve outcomes and have been reviewed. Effective management of COPD in older adults should always consider the ability of patients to properly use inhalers and the involvement of caregivers or family members as a useful support to care, especially when treating cognitively impaired patients. Especially in the older population, timely identification and treatment of comorbidities are also crucial, but evidence in this area is still lacking and clinical practice guidelines do not take comorbidities into account in their recommendations.

SUMMARY

The Global Initiative for Obstructive Lung Disease has recommended criteria for diagnosis and management of COPD in the general population. On the contrary, available evidence suggests practical limitations in diagnostic approach and intervention strategies in older patients with stable COPD that need to be further studied for a translation into clinical practice guidelines.

Results of noninvasive ventilation in very old patients

Background

Noninvasive ventilation (NIV) is frequently used for the management of acute respiratory failure (ARF) in very old patients (≥ 80 years), often in the context of a do-not-intubate order (DNI). We aimed to determine its efficacy and long-term outcome.

Methods

Prospective cohort of all patients admitted to the medical ICU of a tertiary hospital during a 2-year period and managed using NIV. Characteristics of patients, context of NIV, and treatment intensity were compared for very old and younger patients. Six-month survival and functional status were assessed in very old patients.

Results

During the study period, 1,019 patients needed ventilatory support and 376 (37%) received NIV. Among them, 163 (16%) very old patients received ventilatory support with 60% of them managed using NIV compared with 32% of younger patients (p < 0.0001). Very old patients received NIV more frequently with DNI than in younger patients (40% vs. 8%). Such cases were associated with high mortality for both very old and younger patients. Hospital mortality was higher in very old than in younger patients but did not differ when NIV was used for cardiogenic pulmonary edema or acute-on-chronic respiratory failure (20% vs. 15%) and in postextubation (15% vs. 17%) out of a context of DNI. Six-month mortality was 51% in very old patients, 67% for DNI patients, and 77% in case of NIV failure and endotracheal intubation. Of the 30 hospital survivors, 22 lived at home and 13 remained independent for activities of daily living.

Conclusions

Very old patients managed using NIV have an overall satisfactory 6-month survival and functional status, except for endotracheal intubation after NIV failure.

Intensive care of the cancer patient: recent achievements and remaining challenges

A few decades have passed since intensive care unit (ICU) beds have been available for critically ill patients with cancer. Although the initial reports showed dismal prognosis, recent data suggest that an increased number of patients with solid and hematological malignancies benefit from intensive care support, with dramatically decreased mortality rates. Advances in the management of the underlying malignancies and support of organ dysfunctions have led to survival gains in patients with life-threatening complications from the malignancy itself, as well as infectious and toxic adverse effects related to the oncological treatments. In this review, we will appraise the prognostic factors and discuss the overall perspective related to the management of critically ill patients with cancer. The prognostic significance of certain factors has changed over time. For example, neutropenia or autologous bone marrow transplantation (BMT) have less adverse prognostic implications than two decades ago. Similarly, because hematologists and oncologists select patients for ICU admission based on the characteristics of the malignancy, the underlying malignancy rarely influences short-term survival after ICU admission. Since the recent data do not clearly support the benefit of ICU support to unselected critically ill allogeneic BMT recipients, more outcome research is needed in this subgroup. Because of the overall increased survival that has been reported in critically ill patients with cancer, we outline an easy-to-use and evidence-based ICU admission triage criteria that may help avoid depriving life support to patients with cancer who can benefit. Lastly, we propose a research agenda to address unanswered questions.

The difficult-to-wean patient

Up to 20% of patients requiring mechanical ventilation will suffer from difficult weaning (the need of more than 7 days of weaning after the first spontaneous breathing trial), which may depend on several reversible causes: respiratory and/or cardiac load, neuromuscular and neuropsychological factors, and metabolic and endocrine disorders. Clinical consequences (and/or often causes) of prolonged mechanical ventilation comprise features such as myopathy, neuropathy, and body composition alterations and depression, which increase the costs, morbidity and mortality of this. These difficult-to-wean patients may be managed in two type of units: respiratory intermediate-care units and specialized regional weaning centers. Two weaning protocols are normally used: progressive reduction of ventilator support (which we usually use), or progressively longer periods of spontaneous breathing trials. Physiotherapy is an important component of weaning protocols. Weaning success depends strongly on patients&#x2019; complexity and comorbidities, hospital organization and personnel expertise, availability of early physiotherapy, use of weaning protocols, patients&#x2019; autonomy and families&#x2019; preparation for home discharge with mechanical ventilation.

Use of noninvasive ventilation on internal wards for elderly patients with limitations to respiratory care: a cohort study

BACKGROUND

The use of noninvasive positive pressure ventilation (NPPV) outside the intensive wards has been evaluated in patients with no limitation on life-sustaining support. Our aim was to evaluate its usefulness in general wards for patients with NPPV as the ceiling of ventilator care when admission to the intensive care unit (ICU) has been withheld.

MATERIALS AND METHODS

Noninvasive positive pressure ventilation was used in 44 patients with acute respiratory failure (ARF) and limitations to respiratory care- 22 with chronic obstructive pulmonary disease (COPD) exacerbations and 22 with acute cardiogenic pulmonary oedema (CPE). Survival at hospital discharge, and survival and readmission rate at 12 months were assessed.

RESULTS

Sixty-three per cent of COPD and 55% of CPE patients survived hospital discharge; and 50% and 37% respectively, were alive after 1 year. The cause of the in-hospital mortality was related to the admission diagnosis in 88% of cases. Cancer in COPD patients [P = 0·040, odds ratio (OR) = 15, 95% CI = 1·14-198] and the completion of NPPV treatment in both diseases (P = 0·008, OR = 0·03, 95% CI = 0·00-0·39 for COPD and P = 0·010, OR = 0·04, 95% CI = 0·00-0·45 for CPE) were related to in-hospital mortality. Fifty-six per cent of COPD and 33% of CPE patients that survived hospital admission were readmitted.

CONCLUSIONS

Our study suggests that the use of NPPV in general wards could be a safe and effective option, as a last choice treatment, in patients with NPPV as the ceiling of ventilator care when admission to ICU has been withheld.
