Do-not-resuscitate orders in patients with community-acquired pneumonia: a retrospective study

Antibiotics at life's end: key role in treating end-of-life pneumonia?

INTRODUCTION

Pneumonia is a common occurrence at the end of life (EOL). However, clear definitions and consensual guidelines for managing this condition are lacking. Diagnosing EOL pneumonia and deciding whether to treat it with antibiotics can be challenging.

AREA COVERED

This special report provides a narrative review of epidemiological data, diagnostic tools for EOL pneumonia, guidance on antibiotic use, and ethical considerations in this context. Literature from 2000 to 2024 was analyzed using PubMed and Cochrane databases.

EXPERT OPINION

At the EOL, respiratory symptoms must be managed to improve patients' quality of life. Bacterial pneumonia can be difficult to diagnose, and the benefits of antibiotics on respiratory symptoms remain uncertain. At an individual level, adverse events may impact EOL quality, while at a population level, overprescribing antibiotics contributes to antimicrobial resistance. A multidisciplinary approach is therefore essential. Treatment goals should be established with the patient or their healthcare representative. If antibiotics are prescribed, they should be initiated for a limited duration with daily reassessments. If the set goals are not achieved or if adverse events occur, antibiotics should be discontinued. Palliative care measures should also be introduced as early as possible.

Goals of care discussions and treatment limitation decisions in European acute geriatric units: a one-day cross-sectional study

BACKGROUND

It is important to pursue goal-concordant care and to prevent non-beneficial interventions in older people.

AIM

To describe serious illness communication and decision-making practices in hospitalised older people in Europe.

SETTING/PARTICIPANTS

Data on advance directives, goals of care (GOC) discussions and treatment limitation decisions were collected about patients aged 75-years and older admitted to 23 European acute geriatric units (AGUs).

RESULTS

In this cohort of 590 older persons [59.5% aged 85 and above, 59.3% female, median premorbid Clinical Frailty Score (CFS) 6], a formal advance directive was recorded in 3.3% and a pre-hospital treatment limitation in 14.0% with significant differences between European regions (respectively P < 0.001 and P = 0.018).Most prevalent GOC was preservation of function (46.8%). GOC were discussed with patients in 64.0%, with families in 73.0%, within the interprofessional hospital team in 67.0% and with primary care in 13.4%. The GOC and the extent to which it was discussed differed between European regions (both P < 0.001). The prevalence of treatment limitation decisions was 53.7% with a large difference within and between countries (P < 0.001). The odds of having a treatment limitation decision were higher for patients with pre-hospital treatment limitation decisions (OR 39.1), residing in Western versus Southern Europe (OR 4.8), belonging to an older age category (OR 3.2), living with a higher number of severe comorbidities (OR 2.2) and higher premorbid CFS (OR 1.3).

CONCLUSIONS

There is large variability across European AGUs concerning GOC discussions and treatment limitation decisions. Sharing of information between primary and hospital care about patient preferences is noticeably deficient.

Reassessing Halm's clinical stability criteria in community-acquired pneumonia management

BACKGROUND

Halm's clinical stability criteria have long guided antibiotic treatment and hospital discharge decisions for patients hospitalised with community-acquired pneumonia (CAP). Originally introduced in 1998, these criteria were established based on a relatively small and select patient population. Consequently, our study aims to reassess their applicability in the management of CAP in a contemporary real-world setting.

METHODS

This cohort study included 2918 immunocompetent patients hospitalised with CAP from three hospitals in Denmark between 2017 and 2020. The primary outcome was time to achieve clinical stability as defined by Halm's criteria. Additionally, we examined recurrence of clinical instability and severe complications. Cumulative incidence function or Kaplan-Meier survival curves were used to analyse these outcomes, considering competing risks.

RESULTS

The study population primarily comprised elderly individuals (median age 75 years) with significant comorbidities. The median time to clinical stability according to Halm's criteria was 4 days, with one-fifth experiencing recurrence of instability after early clinical response (stability within 3 days). Severe complications within 30 days mainly comprised mortality, with rates of 5.1% (64/1257) overall in those with early clinical response, 1.7% (18/1045) in the subgroup without do-not-resuscitate orders and 17.3% (276/1595) among the rest.

CONCLUSION

Halm's clinical stability criteria effectively classify CAP patients with different disease courses, yet achieving stability required more time in this ageing population with substantial comorbidities and more severe disease. Early clinical response indicates reduced risk of complications, especially in those without do-not-resuscitate orders.

Clinical factors associated with in-hospital mortality in elderly versus non-elderly pneumonia patients in the emergency department

BACKGROUND

Pneumonia is a respiratory infection with an increasing incidence with age. However, limited evidence has identified factors associated with its outcome among different age groups, especially in the elderly and in the emergency department (ED) setting. We aimed to identify clinical factors associated with in-hospital mortality in elderly versus non-elderly pneumonia patients in the ED.

METHODS

A retrospective observational study was conducted at the ED of Siriraj Hospital, Thailand. Patients aged at least 18 years old diagnosed with non-COVID pneumonia between June 1, 2021, and May 31, 2022, were included. They were categorized into the elderly (age ≥ 65 years) and non-elderly (age < 65 years) groups. The primary outcome was in-hospital mortality. We employed multivariate logistic regression models to identify independent factors associated with the outcome in each age group.

RESULTS

We enrolled 735 patients, 515 elderly and 222 non-elderly. There was no difference in in-hospital mortality rate between the two groups (39.0% in the elderly and 32.9% in the non-elderly; p = 0.116). In the elderly cohort, independent factors associated with in-hospital mortality were do-not-resuscitate (DNR) status (adjusted odds ratio (aOR) 12.89; 95% confidence interval (CI) 7.19-23.1; p < 0.001), Glasgow Coma Scale (GCS) score (aOR 0.91; 95%CI 0.85-0.96; p = 0.002), hemoglobin level (aOR 0.9; 95%CI 0.82-0.98; p = 0.012) and the type of initial oxygen support (p = 0.05). Among non-elderly patients, independent factors were DNR status (aOR 6.81; 95%CI 3.18-14.59; p < 0.001), GCS score (aOR 0.89; 95%CI 0.8-0.99; p = 0.025), platelet level (aOR 1; 95%CI 1-1; p = 0.038), Charlson Comorbidity Index (CCI) (aOR 1.12; 95%CI 0.99-1.28; p = 0.078), and the type of initial oxygen support p = 0.079).

CONCLUSION

In pneumonia patients presenting to the ED, DNR status, lower GCS score, and more invasive initial oxygen supplementation were independently associated with in-hospital mortality in both elderly and non-elderly groups. However, lower hemoglobin level was only associated with in-hospital mortality in the elderly, while higher CCI and lower platelet count were independent factors only in the non-elderly. These findings emphasize the importance of age-specific considerations for the disease, and these factors are potential prognostic markers that may be used in clinical practice to improve patient outcomes.

One-Year Medical Utilization and Mortality in Home Health and Nursing Home Care Recipients from Northern Taiwan

OBJECTIVES

Home health care (HHC) and nursing home care (NHC) are mainstays of long-term service in the aged population. Therefore, we aimed to investigate the factors associated with 1-year medical utilization and mortality in HHC and NHC recipients in Northern Taiwan.

DESIGN

This study employed a prospective cohort design.

SETTING AND PARTICIPANTS

We enrolled 815 HHC and NHC participants who started receiving medical care services from the National Taiwan University Hospital, Beihu Branch between January 2015 and December 2017.

METHODS

Multivariate Poisson regression modeling was used to quantify the relationship between care model (HHC vs NHC) and medical utilization. Cox proportional-hazards modeling was used to estimate hazard ratios and factors associated with mortality.

RESULTS

Compared with NHC recipients, HHC recipients had higher 1-year utilization of emergency department services [incidence rate ratio (IRR) 2.04, 95% CI 1.16-3.59] and hospital admissions (IRR 1.49, 95% CI 1.14-1.93), as well as longer total hospital length of stay (LOS) (IRR 1.61, 95% CI 1.52-1.71) and LOS per hospital admission (IRR 1.31, 95% CI 1.22-1.41). Living at home or in a nursing home did not affect the 1-year mortality.

CONCLUSIONS AND IMPLICATIONS

Compared with NHC recipients, HHC recipients had a higher number of emergency department services and hospital admissions, as well as longer hospital LOS. Policies should be developed to reduce emergency department and hospitalization utilization in HHC recipients.

Interventions to improve outcomes in community-acquired pneumonia

INTRODUCTION

Community-acquired pneumonia (CAP) is a common infection associated with high morbimortality and a highly deleterious impact on patients' quality of life and functionality. We comprehensively review the factors related to the host, the causative microorganism, the therapeutic approach and the organization of health systems (e.g. setting for care and systems for allocation) that might have an impact on CAP-associated outcomes. Our main aims are to discuss the most controversial points and to provide some recommendations that may guide further research and the management of patients with CAP, in order to improve their outcomes, beyond mortality.

AREA COVERED

In this review, we aim to provide a critical account of potential measures to improve outcomes of CAP and the supporting evidence from observational studies and clinical trials.

EXPERT OPINION

CAP is associated with high mortality and a highly deleterious impact on patients' quality of life. To improve CAP-associated outcomes, it is important to understand the factors related to the patient, etiology, therapeutics, and the organization of health systems.

Predictors of outcomes in emergency department patients with suspected infections and without fulfillment of the sepsis criteria

BACKGROUND

Data on patient characteristics and determinants of serious outcomes for acutely admitted patients with infections who do not fulfill the sepsis criteria are sparse. The study aimed to characterize acutely admitted emergency department (ED) patients with infections and a composite outcome of in-hospital mortality or transfer to the intensive care unit without fulfilling the criteria for sepsis and to examine predictors of the composite outcome.

METHODS

This was a secondary analysis of data from a prospective observational study of patients with suspected bacterial infection admitted to the ED between October 1, 2017 and March 31, 2018. A National Early Warning Score 2 (NEWS2) ≥ 5 within the first 4 h in the ED was assumed to represent a sepsis-like condition with a high risk for the composite endpoint. Patients who achieved the composite outcome were grouped according to fulfillment of the NEWS2 ≥ 5 criteria. We used logistic regression analysis to estimate the unadjusted and adjusted odds ratio (OR) for the composite endpoint among patients with either NEWS2  < 5 (NEWS2-) or NEWS2  ≥ 5 (NEWS2+).

RESULTS

A total of 2055 patients with a median age of 73 years were included. Of these, 198 (9.6%) achieved the composite endpoint, including 59 (29.8%) NEWS2- and 139 (70.2%) NEWS2+ patients, respectively. Diabetes (OR 2.23;1.23-4.0), a Sequential Organ Failure Assessment (SOFA) score ≥ 2 (OR 2.57;1.37-4.79), and a Do-not-attempt-cardiopulmonary-resuscitation order (DNACPR) on admission (OR 3.70;1.75-7.79) were independent predictive variables for the composite endpoint in NEWS2- patients (goodness-of-fit test P = 0.291; area under the receiver operating characteristic curve for the model (AUROC) = 0.72). The regression model for NEWS2+ patients revealed that a SOFA score ≥ 2 (OR 2.79; 1.59-4.91), hypothermia (OR 2.48;1.30-4.75), and DNACPR order on admission were predictive variables for the composite endpoint (goodness-of-fit test P = 0.62; AUROC for the model = 0.70).

CONCLUSION

Approximately one-third of the patients with infections and serious outcomes during hospitalization did not meet the NEWS2 threshold for likely sepsis. Our study identified factors with independent predictive values for the development of serious outcomes that should be tested in future prediction models.

Association between Barthel Index, Grip Strength, and Physical Activity Level at Admission and Prognosis in Community-Acquired Pneumonia: A Prospective Cohort Study

Background: Impaired functional status is a risk factor for hospitalization in patients with community-acquired pneumonia (CAP). The aim was to determine the influence of functional status and physical activity level on severe outcomes, including length of stay, admission to the intensive care unit (ICU), readmission, and mortality in patients with CAP. Methods: A prospective cohort study among patients hospitalized with CAP. Functional status was assessed with the Barthel index and grip strength, and physical activity level was assessed using the international physical activity questionnaire. Linear regression was used to assess the association with length of stay, and logistic regression was used to assess the risk of severe outcomes. Results: Among 355 patients admitted with CAP, 18% had a low Barthel index (<80), 45% had a low grip strength, and 75% had a low physical activity level. Low Barthel index was associated with increased risk of ICU admission (OR 3.6, 95% CI 1.2−10.9), longer length of stay (27.9%, 95% CI 2.3−59.7%), readmission within 30, 90, and 180 days (OR 2.1−2.4, p < 0.05), and mortality within 90 and 180 days (OR 4.2−5.0, p < 0.05). Low grip strength was associated with increased risk of 90 days readmission (OR 1.6, 95% CI 1.0−2.6, p < 0.05) and mortality within 30, 90, and 180 days (OR 2.6−3.2, p < 0.05). Low physical activity level was associated with increased risk of readmission within 90 and 180 days (OR 1.8−2.1, p < 0.05) and mortality within 30, 90, and 180 days (OR 3.3−5.5, p < 0.05). Conclusions: Impaired functional status and low physical activity level were associated with a longer length of stay and increased risk of ICU admission, readmission, and mortality in patients hospitalized with CAP. Routine assessment of functional status and physical activity level in clinical care could enable early identification of individuals with excess risk for a poor prognosis.

Do-Not-Attempt-Cardiopulmonary-Resuscitation (DNACPR) decisions in patients admitted through the emergency department in a Swedish University Hospital – An observational study of outcome, patient characteristics and changes in DNACPR decisions

Aims

The aims were to examine patient and hospital characteristics associated with Do-Not-Attempt-Cardiopulmonary-Resuscitation (DNACPR) decisions for adult admissions through the emergency department (ED), for patients with DNACPR decisions to examine patient and hospital characteristics associated with hospital mortality, and to explore changes in CPR status.

Methods

This was a retrospective observational study of adult patients admitted through the ED at Karolinska University Hospital 1 January to 31 October 2015.

Results

The cohort included 25,646 ED admissions, frequency of DNACPR decisions was 11% during hospitalisation. Patients with DNACPR decisions were older, with an overall higher burden of chronic comorbidities, unstable triage scoring, hospital mortality and one-year mortality compared to those without. For patients with DNACPR decisions, 63% survived to discharge and one-year mortality was 77%. Age and comorbidities for patients with DNACPR decisions were similar regardless of hospital mortality, those who died showed signs of more severe acute illness on ED arrival. Change in CPR status during hospitalisation was 5% and upon subsequent admission 14%. For patients discharged with DNACPR decisions, reversal of DNACPR status upon subsequent admission was 32%, with uncertainty as to whether this reversal was active or a consequence of a lack of consideration.

Conclusion

For a mixed population of adults admitted through the ED, frequency of DNACPR decisions was 11%. Two-thirds of patients with DNACPR decisions were discharged, but one-year mortality was high. For patients discharged with DNACPR decisions, reversal of DNACPR status was substantial and this should merit further attention.

Do not attempt cardiopulmonary resuscitation (DNACPR) decisions in people admitted with suspected COVID-19: Secondary analysis of the PRIEST observational cohort study

AIMS

We aimed to describe the characteristics and outcomes of adults admitted to hospital with suspected COVID-19 according to their DNACPR decisions, and identify factors associated with DNACPR decisions.

METHODS

We undertook a secondary analysis of 13,977 adults admitted to hospital with suspected COVID-19 and included in the Pandemic Respiratory Infection Emergency System Triage (PRIEST) study. We recorded presenting characteristics and outcomes (death or organ support) up to 30 days. We categorised patients as early DNACPR (before or on the day of admission) or late/no DNACPR (no DNACPR or occurring after the day of admission). We undertook descriptive analysis comparing these groups and multivariable analysis to identify independent predictors of early DNACPR.

RESULTS

We excluded 1249 with missing DNACPR data, and identified 3929/12748 (31%) with an early DNACPR decision. They had higher mortality (40.7% v 13.1%) and lower use of any organ support (11.6% v 15.7%), but received a range of organ support interventions, with some being used at rates comparable to those with late or no DNACPR (e.g. non-invasive ventilation 4.4% v 3.5%). On multivariable analysis, older age (p < 0.001), active malignancy (p < 0.001), chronic lung disease (p < 0.001), limited performance status (p < 0.001), and abnormal physiological variables were associated with increased recording of early DNACPR. Asian ethnicity was associated with reduced recording of early DNACPR (p = 0.001).

CONCLUSIONS

Early DNACPR decisions were associated with recognised predictors of adverse outcome, and were inversely associated with Asian ethnicity. Most people with an early DNACPR decision survived to 30 days and many received potentially life-saving interventions.

Differences in Characteristics, Hospital Care and Outcomes between Acute Critically Ill Emergency Department Patients with Early and Late Do-Not-Resuscitate Orders

Background: A do-not-resuscitate (DNR) order is associated with an increased risk of death among emergency department (ED) patients. Little is known about patient characteristics, hospital care, and outcomes associated with the timing of the DNR order. Aim: Determine patient characteristics, hospital care, survival, and resource utilization between patients with early DNR (EDNR: signed within 24 h of ED presentation) and late DNR orders. Design: Retrospective observational study. Setting/Participants: We enrolled consecutive, acute, critically ill patients admitted to the emergency intensive care unit (EICU) at Taipei Veterans General Hospital from 1 February 2018, to 31 January 2020. Results: Of the 1064 patients admitted to the EICU, 619 (58.2%) had EDNR and 445 (41.8%) LDNR. EDNR predictors were age >85 years (adjusted odd ratios (AOR) 1.700, 1.027–2.814), living in long-term care facilities (AOR 1.880, 1.066–3.319), having advanced cardiovascular diseases (AOR 2.128, 1.039–4.358), “medical staff would not be surprised if the patient died within 12 months” (AOR 1.725, 1.193–2.496), and patients’ family requesting palliative care (AOR 2.420, 1.187–4.935). EDNR patients underwent lesser endotracheal tube (ET) intubation (15.6% vs. 39.9%, p < 0.001) and had reduced epinephrine injection (19.9% vs. 30.3%, p = 0.009), ventilator support (16.7% vs. 37.9%, p < 0.001), and narcotic use (51.1% vs. 62.6%, p = 0.012). EDNR patients had significantly lower 7-day (p < 0.001), 30-day (p < 0.001), and 90-day (p = 0.023) survival. Conclusions: EDNR patients underwent decreased ET intubation and had reduced epinephrine injection, ventilator support, and narcotic use during EOL as well as decreased length of hospital stay, hospital expenditure, and survival compared to LDNR patients.
