[PMID: 39115964 DOI: 10.1080/23744235.2024.2390180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2024] [Revised: 07/26/2024] [Accepted: 08/04/2024] [Indexed: 08/10/2024] Open
Abstract
INTRODUCTION Pneumonia is one of the most common causes of hospital admissions in the United States and remains a major cause of death. However, less is known regarding the mortality burden from pneumonia in the United States and how this burden has changed over time. METHODS Death rates from causes related to pneumonia were determined using the CDC Wide-ranging Online Data for Epidemiologic Research (WONDER) data from 1999-2019. Pneumonia deaths were calculated for the overall population as well as for sociodemographic subgroups. We also analysed changes in death rates over time. RESULTS Overall, 2.1% of total US deaths during the period between 1999 and 2019 were due to pneumonia (2.6% in 1999 and 1.5% in 2019). Mortality declined over time for both men and women, and across most age cohorts, as well as all racial, urbanisation, and regional categories. Rates of pneumonia deaths were higher among males as compared to females (age-adjusted mortality rate ratio (AAMRR) = 1.35; 95% CI: 1.34-1.35). Compared to White Americans, Black Americans had the highest pneumonia-related mortality rates of any racial group (AAMRR = 1.11; 95% CI: 1.10-1.11). CONCLUSIONS Rates of pneumonia-related death have decreased in the United States in recent decades. However, significant racial and gender disparities remain, indicating the need for more equitable care.

Long-Term Exposure to Air Pollution and Risk of Acute Lower Respiratory Infections in the Danish Nurse Cohort. Ann Am Thorac Soc 2024; 21:1129-1138. [PMID: 38513223 DOI: 10.1513/annalsats.202401-074oc] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Accepted: 03/21/2024] [Indexed: 03/23/2024] Open
Abstract
Rationale: Air pollution is a major risk factor for chronic cardiorespiratory diseases, affecting the immune and respiratory systems' functionality, but epidemiological evidence in respiratory infections remains sparse. Objectives: We aimed to assess the association of long-term exposure to ambient air pollution with the risk of developing new and recurrent acute lower respiratory infections (ALRIs), characterized by persistently severe symptoms necessitating hospital contact, and identify the potential susceptible populations by socioeconomic status, smoking, physical activity status, overweight, and comorbidity with chronic lung disease. Methods: We followed 23,912 female nurses from the Danish Nurse Cohort (age >44 yr) from baseline (1993 or 1999) until 2018 for incident and recurrent ALRIs defined by hospital contact (inpatient, outpatient, and emergency room) data from the National Patient Register. Residential annual mean concentrations of fine particulate matter, nitrogen dioxide (NO2), and black carbon were modeled using the Danish Eulerian Hemispheric Model/Urban Background Model/Air Geographic Information System. We used marginal Cox models with time-varying exposures to assess the association of 3-year running mean air pollution level with incident and recurrent ALRIs and examined effect modification by age, socioeconomic status, smoking, physical activity, body mass index, and comorbidity with asthma or chronic obstructive pulmonary disease (COPD). Results: During a 21.3-year mean follow-up, 4,746 ALRIs were observed, of which 2,553 were incident. We observed strong positive associations of all three pollutants with incident ALRIs, with hazard ratios and 95% confidence intervals of 1.19 (1.08-1.31) per 2.5 μg/m3 for fine particulate matter, 1.17 (1.11-1.24) per 8.0 μg/m3 for NO2, and 1.09 (1.05-1.12) per 0.3 μg/m3 for black carbon, and slightly stronger associations with recurrent ALRIs. Associations were strongest in patients with COPD and nurses with low physical activity. Conclusions: Long-term exposure to air pollution at low levels was associated with risks of new and recurrent ALRIs, with patients with COPD and physically inactive subjects most vulnerable.

Community-acquired pneumonia: use of clinical characteristics of acutely admitted patients for the development of a diagnostic model - a cross-sectional multicentre study. BMJ Open 2024; 14:e079123. [PMID: 38816044 PMCID: PMC11141191 DOI: 10.1136/bmjopen-2023-079123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Accepted: 05/20/2024] [Indexed: 06/01/2024] Open
Abstract
OBJECTIVES This study aimed to describe the clinical characteristics of adults with suspected acute community-acquired pneumonia (CAP) on hospitalisation, evaluate their prediction performance for CAP and compare the performance of the model to the initial assessment of the physician. DESIGN Cross-sectional, multicentre study. SETTING The data originated from the INfectious DisEases in Emergency Departments study and were collected prospectively from patient interviews and medical records. The study included four Danish medical emergency departments (EDs) and was conducted between 1 March 2021 and 28 February 2022. PARTICIPANTS A total of 954 patients admitted with suspected infection were included in the study. PRIMARY AND SECONDARY OUTCOME The primary outcome was CAP diagnosis assessed by an expert panel. RESULTS According to expert evaluation, CAP had a 28% prevalence. 13 diagnostic predictors were identified using least absolute shrinkage and selection operator regression to build the prediction model: dyspnoea, expectoration, cough, common cold, malaise, chest pain, respiratory rate (>20 breaths/min), oxygen saturation (<96%), abnormal chest auscultation, leucocytes (<3.5×109/L or >8.8×109/L) and neutrophils (>7.5×109/L). C reactive protein (<20 mg/L) and having no previous event of CAP contributed negatively to the final model. The predictors yielded good prediction performance for CAP with an area under the receiver-operator characteristic curve (AUC) of 0.85 (CI 0.77 to 0.92). However, the initial diagnosis made by the ED physician performed better, with an AUC of 0.86 (CI 84% to 89%). CONCLUSION Typical respiratory symptoms combined with abnormal vital signs and elevated infection biomarkers were predictors for CAP on admission to an ED. The clinical value of the prediction model is questionable in our setting as it does not outperform the clinician's assessment. Further studies that add novel diagnostic tools and use imaging or serological markers are needed to improve a model that would help diagnose CAP in an ED setting more accurately. TRIAL REGISTRATION NUMBER NCT04681963.

Inhaled corticosteroid treatment and pneumonia in patients with chronic obstructive pulmonary disease - nationwide development from 1998 to 2018. Eur Clin Respir J 2024; 11:2359768. [PMID: 38817947 PMCID: PMC11138226 DOI: 10.1080/20018525.2024.2359768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2024] [Accepted: 05/21/2024] [Indexed: 06/01/2024] Open
Abstract
Background A decreasing use of inhaled corticosteroids (ICS) in patients with a hospital-registered diagnosis of chronic obstructive pulmonary disease (COPD) has recently been documented in Denmark. ICS treatment is not recommended in patients with high pneumonia risk, and we aimed to assess the development of ICS treatment in relation to pneumonia occurrence. Methods Annual nationwide register-based cross-sectional studies from 1998 to 2018 including all patients ≥40 years of age with a hospital-registered ICD-10 diagnosis of COPD on the 31st of December each year. We calculated the annual proportion of patients with at least one outpatient pneumonia (redeemed prescription of relevant antibiotics) or pneumonia hospitalization (hospitalization or ER visit), and stratified by ICS dose (No ICS, low dose, medium dose, or high dose). Results The study population increased from 35,656 patients in 1998 to 99,057 patients in 2018. The annual proportion of patients experiencing a pneumonia decreased from 69.4% to 55.2%. The proportion of patients with at least one outpatient pneumonia, but no hospitalization, decreased (59.2% to 46.2%). The overall proportion of patients with at least one pneumonia hospitalization remained unchanged (10.2% to 9.0%), but this proportion increased in patients in high dose ICS (9.9% to 14.6%). The overall proportion of patients in high dose treatment decreased (12.7% to 5.7%), but not in patients with pneumonia hospitalization (16.5% to 15.1). Conclusions Our study demonstrates a nationwide decrease from 1998 to 2018 in the proportion of patients who redeemed a prescription for antibiotics used mainly for respiratory tract infections, which may reflect a decrease in the number of outpatient pneumonias. This decrease was largely caused by an increase in the number of patients without pneumonia. No differences over time were seen regarding hospitalization-requiring pneumonia. High dose ICS treatment was unchanged in patients with hospitalization-requiring pneumonia.

Development of an Implementation Strategy Tailored to Deliver Evidence-Based and Person-Centred Nursing Care for Patients with Community-Acquired Pneumonia: An Intervention Mapping Approach. Healthcare (Basel) 2023; 12:32. [PMID: 38200938 PMCID: PMC10779328 DOI: 10.3390/healthcare12010032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 12/18/2023] [Accepted: 12/19/2023] [Indexed: 01/12/2024] Open
Abstract
Community-acquired pneumonia is a serious public health problem, and more so in older patients, leading to high morbidity and mortality. However, this problem can be reduced by optimising in-hospital nursing care. Accordingly, this study describes a systematic process of designing and developing a tailored theory- and research-based implementation strategy that supports registered nurses (RNs) in delivering evidence-based and person-centred care for this patient population in a hospital setting. The implementation strategy was developed by completing the six steps of the Intervention Mapping framework: (1) developing a logic model of the problem and (2) a logic model of change by defining performance and change objectives, (3) designing implementation strategy interventions by selecting theory-based change methods, (4) planning the interventions and producing materials through a co-design approach, (5) developing a structured plan for adoption, maintenance and implementation and (6) developing an evaluation plan. This method can serve as a guide to (1) target behavioural and environmental barriers hindering the delivery of nursing care in local clinical practice, (2) support evidence uptake, (3) support RNs in the delivery of nursing care according to individual patient needs and thereby (4) optimise health-related patient outcomes.

Evaluation of point-of-care multiplex polymerase chain reaction in guiding antibiotic treatment of patients acutely admitted with suspected community-acquired pneumonia in Denmark: A multicentre randomised controlled trial. PLoS Med 2023; 20:e1004314.

Abstract
BACKGROUND Rapid and accurate detection of pathogens is needed in community-acquired pneumonia (CAP) to enable appropriate antibiotics and to slow the development of antibiotic resistance. We aimed to compare the effect of point-of-care (POC) polymerase chain reaction (PCR) detection of respiratory pathogens added to standard care with standard care only (SCO) on antibiotic prescriptions after acute hospital admission. METHODS AND FINDINGS We performed a superiority, parallel-group, open-label, multicentre, randomised controlled trial (RCT) in 3 Danish medical emergency departments (EDs) from March 2021 to February 2022. Adults acutely admitted with suspected CAP during the daytime on weekdays were included and randomly assigned (1:1) to POC-PCR (The Biofire FilmArray Pneumonia Panel plus added to standard care) or SCO (routine culture and, if requested by the attending physician, target-specific PCR) analysis of respiratory samples. We randomly assigned 294 patients with successfully collected samples (tracheal secretion 78.4% or expectorated sputum 21.6%) to POC-PCR (n = 148, 50.4%) or SCO (146, 49.6%). Patients and investigators owning the data were blinded to the allocation and test results. Outcome adjudicators and clinical staff at the ED were not blinded to allocation and test results but were together with the statistician, blinded to data management and analysis. Laboratory staff performing standard care analyses was blinded to allocation. The study coordinator was not blinded. Intention-to-treat and per protocol analysis were performed using logistic regression with Huber-White clustered standard errors for the prescription of antibiotic treatment. Loss to follow-up comprises 3 patients in the POC-PCR (2%) and none in the SCO group. Intention-to-treat analysis showed no difference in the primary outcome of prescriptions of no or narrow-spectrum antibiotics at 4 h after admission for the POC-PCR (n = 91, 62.8%) odds ratio (OR) 1.13; (95% confidence interval (CI) [0.96, 1.34] p = 0.134) and SCO (n = 87, 59.6%). Secondary outcomes showed that prescriptions were significantly more targeted at 4-h OR 5.68; (95% CI [2.49, 12.94] p < 0.001) and 48-h OR 4.20; (95% CI [1.87, 9.40] p < 0.001) and more adequate at 48-h OR 2.11; (95% CI [1.23, 3.61] p = 0.006) and on day 5 in the POC-PCR group OR 1.40; (95% CI [1.18, 1.66] p < 0.001). There was no difference between the groups in relation to intensive care unit (ICU) admissions OR 0.54; (95% CI [0.10, 2.91] p = 0.475), readmission within 30 days OR 0.90; (95% CI [0.43, 1.86] p = 0.787), length of stay (LOS) IRR 0.82; (95% CI [0.63, 1.07] p = 0.164), 30 days mortality OR 1.24; (95% CI [0.32, 4.82] p = 0.749), and in-hospital mortality OR 0.98; (95% CI [0.19, 5.06] p = 0.986). CONCLUSIONS In a setting with an already restrictive use of antibiotics, adding POC-PCR to the diagnostic setup did not increase the number of patients treated with narrow-spectrum or without antibiotics. POC-PCR may result in a more targeted and adequate use of antibiotics. A significant study limitation was the concurrent Coronavirus Disease 2019 (COVID-19) pandemic resulting in an unusually low transmission of respiratory virus.

Abstract
Community-acquired pneumonia (CAP) is an acute infection involving the parenchyma of the lungs, which is acquired outside of the hospital. Population-wide real-world data and artificial intelligence (AI) were used to develop a disease risk score for CAP hospitalization among older individuals. The source population included residents in Denmark aged 65 years or older in the period January 1, 1996, to July 30, 2018. 137344 individuals were hospitalized for pneumonia during the study period for which, 5 controls were matched leading to a study population of 620908 individuals. The disease risk had an average accuracy of 0.79 based on 5-fold cross-validation in predicting CAP hospitalization. The disease risk score can be useful in clinical practice to identify individuals at higher risk of CAP hospitalization and intervene to minimize their risk of being hospitalized for CAP.

Abstract
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.

Abstract
BACKGROUND Pneumonia is a very common infection in the cognitively impaired adult population, often leading to long-term deterioration, in physical and cognitive performance. Evidence is lacking on whether chronic comorbidities and drug use are risk factors for pneumonia in persons with Alzheimer's disease (AD). The objective of this study was to investigate the risk factors of pneumonia in community dwellers with and without AD. METHODS We performed a retrospective register-based study utilizing the Medication Use and Alzheimer's disease (MEDALZ) cohort, which is based on Finnish nationwide healthcare registers and includes all community dwellers who received a verified clinical diagnosis of AD between 2005 to 2011. This study comprised 69,350 persons with AD and 69,350 persons without AD matched by age, gender, and region of residence. Association between comorbidities, drug use, and hospitalization due to pneumonia were assessed using Cox Regression. RESULTS During the follow-up, 25.0% (n = 17,105) of the AD cohort and 15.8% (n = 10,966) of the non-AD cohort were hospitalized due to pneumonia. Persons with AD had a higher risk of pneumonia also after adjusting for comorbidities (HR 1.76, 95% CI 1.71-1.80). Previous pneumonia was the strongest risk factor for pneumonia in both cohorts. All comorbidities and drug use excluding biological product use were associated with a higher risk of pneumonia, but stronger associations were observed in the non-AD cohort. The risk of hospitalization following psychotropic drug use was proportional to the number of psychotropics utilized. CONCLUSIONS Pneumonia is a serious, potentially life-threatening illness, and risk factors for pneumonia include several potentially avoidable drugs. In addition, good care of existing comorbidities might prevent pneumonia and related hospitalization.

Using a modified season-specific approach over nine consecutive influenza seasons, we investigated influenza vaccination coverage and effectiveness in a population-based nationwide cohort study that included all SOT recipients aged ≥18 years who were living in Denmark from December 1, 2007 to April 1, 2016. The primary outcome was the season-specific risk of all-cause pneumonia admission. Secondary outcomes were season-specific influenza-related admission, intensive care unit (ICU) admission, and all-cause mortality. Crude and adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs) were estimated using Cox proportional hazards regression models. In total, 11 381 person-years of follow-up data were collected from 5745 SOT recipients, 48% of whom were vaccinated. Influenza vaccination was associated with a reduced risk of all-cause pneumonia admission (aHR, 0.83; 95% CI, 0.69-0.99; p = .035) and all-cause mortality (aHR, 0.60; 95% CI, 0.47-0.76; p = .001), but not influenza-related admission (aHR, 0.75; 95% CI, 0.46-1.22; p = .24) or ICU admission (aHR, 0.84; 95% CI, 0.67-1.06; p = .14) during the same season. Despite these benefits, uptake of influenza vaccination among SOT recipients was low. Therefore, annual influenza vaccination needs to be prioritized.

Abstract
Abstract
Introduction
Despite improvements in medical science and public health, mortality of community-acquired pneumonia (CAP) has barely changed throughout the last 15 years. The current SARS-CoV-2 pandemic has once again highlighted the central importance of acute respiratory infections to human health. The “network of excellence on Community Acquired Pneumonia” (CAPNETZ) hosts the most comprehensive CAP database worldwide including more than 12,000 patients. CAPNETZ connects physicians, microbiologists, virologists, epidemiologists, and computer scientists throughout Europe. Our aim was to summarize the current situation in CAP research and identify the most pressing unmet needs in CAP research.
Methods
To identify areas of future CAP research, CAPNETZ followed a multiple-step procedure. First, research members of CAPNETZ were individually asked to identify unmet needs. Second, the top 100 experts in the field of CAP research were asked for their insights about the unmet needs in CAP (Delphi approach). Third, internal and external experts discussed unmet needs in CAP at a scientific retreat.
Results
Eleven topics for future CAP research were identified: detection of causative pathogens, next generation sequencing for antimicrobial treatment guidance, imaging diagnostics, biomarkers, risk stratification, antiviral and antibiotic treatment, adjunctive therapy, vaccines and prevention, systemic and local immune response, comorbidities, and long-term cardio-vascular complications.
Conclusion
Pneumonia is a complex disease where the interplay between pathogens, immune system and comorbidities not only impose an immediate risk of mortality but also affect the patients’ risk of developing comorbidities as well as mortality for up to a decade after pneumonia has resolved. Our review of unmet needs in CAP research has shown that there are still major shortcomings in our knowledge of CAP.

Abstract
BACKGROUND Pneumonia represents a public health problem of substantial health and economic burden. However, the evidence on the burden of adult pneumonia is limited in China. METHODS The China Kadoorie Biobank recruited 512,725 participants aged 30-79 years from five urban and five rural areas during 2004-2008. The current analyses included 506,086 participants who were alive in 2009. Pneumonia hospitalizations were ascertained through the health insurance system until December 31, 2017. Generalized linear models were used to examine the secular trends and regional and population variations in pneumonia hospitalization rate, mean length of hospital stay (LOS), and 30-day case fatality rate (CFR). FINDINGS A total of 27,879 participants with 36,567 pneumonia hospitalizations were identified with a mean follow-up time of 8·9 years. The unadjusted hospitalization rate was 8·4 (95% confidence interval [CI]: 8·3, 8·6) per 1000 person-years, with an increase of 15·5% annually from 4·2 (3·9, 4·4) in 2009 to 10·9 (10·6, 11·3) in 2017, after adjusting for age, sex, study area. The mean LOS was 8·8 (95% CI: 8·7, 8·9) days, with a slight decrease of 1·0% annually from 2009 to 2017. The average 30-day CFR remained practically unchanged at 2·4 (95% CI: 2·2, 2·5) deaths per 100 admissions. A clear seasonal pattern of pneumonia hospitalization rate was observed, and the hospitalization rate and CFR differed across regions and subpopulations of different ages and underlying conditions. INTERPRETATION There was an increasing hospitalization burden of pneumonia in Chinese adults, especially for adults aged ≥60 years or those with underlying conditions.

Abstract
BACKGROUND Several studies indicate increasing hospitalisation rates for specific infectious diseases (IDs). Studies describing the entire ID spectrum are scarcer. Our aim was to describe hospital use with ID diagnoses in Swedish adults from 1998 to 2019. METHODS All four-position codes in ICD-10 were reclassified as ID or non-ID diagnoses. Using data from the National Patient Register, age-standardised hospitalisation rates and average length-of-stay (LOS) was determined for hospitalisations with ID vs non-ID diagnoses in the primary position at discharge. The 22-year study period was divided into five periods that were compared using standardised rate ratios (SRR). FINDINGS Annual hospitalisations with ID diagnoses increased from 115 thousand in 1998-2002 to 182 thousand in 2015-2019, for a rate increase from 17·4 to 23.0 per 1000 person-years, and a SRR (95%CI) of 1.32 (1.32-1.33). Concurrently, the hospitalisation rate with non-ID diagnoses decreased from 147 to 110, for a SRR of 0.75 (0.75-0.75). Average LOS decreased less for IDs than for non-IDs. Consequently, the proportion of hospital nights for which an ID was considered causing the hospitalisation increased from 11% to 21%. Persons aged 80+ years had the highest ID hospitalisation rate. INTERPRETATION The increased hospital use with ID diagnoses suggests an increasing incidence of severe IDs as well as a changing case-mix of hospitalised patients. Given the anticipated demographic change, this trend is likely to persist. Healthcare systems will need to address IDs in a comprehensive and standardised way.

Abstract
BACKGROUND Depression is highly prevalent among hospitalized patients with pneumonia. At discharge, these patients transfer to a less care-intensive home-based setting. Nevertheless, little is known on the prognosis in the postdischarge period. OBJECTIVE The objective of this study was to investigate the influence of depression on 30-day mortality and readmission in persons discharged after a pneumonia admission. DESIGN This was a population-based cohort study using the Danish registries. SUBJECTS All persons aged 50+ years with a pneumonia admission in 2000-2016 in Denmark. MEASURES Mortality rate ratios for 30-day mortality and incidence rate ratios for 30-day readmission in pneumonia patients with versus without depression. RESULTS We identified 379,265 pneumonia admissions, hereof 83,257 (22.0%) with depression. The overall adjusted mortality rate ratio was 1.29 (95% confidence interval: 1.25-1.33), and the overall adjusted incidence rate ratio was 1.07 (95% confidence interval: 1.05-1.08). The mortality risk was higher for all ages and throughout the 30-day period in persons with versus without depression. This risk was modified by sociodemographic and socioeconomic characteristics (excluding sex and education), admission-related factors, comorbidities, and use of benzodiazepines, opioids, or antipsychotics. The readmission risk was higher until age 90 and tended to be higher throughout the 30-day period. This risk was modified by age, cohabitation, residency, admission-related factors, comorbidities, and use of opioids or antipsychotics. For both outcomes, the relative effect of depression was highest among the youngest, among those with a short hospital stay and among those with few comorbidities. CONCLUSION Depression is an independent risk factor for 30-day mortality and readmission in persons who transfer from hospital care to home-based care.

Abstract
(1) Background: To analyze incidence, clinical characteristics, procedures, and in-hospital outcomes among patients hospitalized with community-acquired pneumonia (CAP) according to the presence of T2DM in Spain (2016-2019) and to assess the role of gender among those with T2DM. (2) Methods: Using the Spanish National Hospital Discharge Database, we estimated hospitalized CAP incidence. Propensity score matching was used to compare population subgroups. (3) Results: CAP was coded in 520,723 patients, of whom 140,410 (26.96%) had T2DM. The hospitalized CAP incidence was higher in patients with T2DM (both sexes) (IRR 4.25; 95% CI 4.23-4.28). The hospitalized CAP incidence was higher in men with T2DM than in women with T2DM (IRR 1.46; 95% CI 1.45-1.47). The hospitalized CAP incidence among T2DM patients increased over time; however, the in-hospital mortality (IHM) decreased between 2016 and 2019. IHM was higher among non-T2DM men and women than matched T2DM men and women (14.23% and 14.22% vs. 12.13% and 12.91%; all p < 0.001, respectively), After adjusting for confounders, men with T2DM had a 6% higher mortality risk than women (OR 1.06; 95% CI 1.02-1.1). (4) Conclusions: T2DM is associated with a higher hospitalized CAP incidence and is increasing overtime. Patients hospitalized with CAP and T2DM have lower IHM. Male sex is a significant risk factor for mortality after CAP among T2DM patients.

Abstract
BACKGROUND Community-acquired pneumonia (CAP) is associated with significant morbidity and mortality. Non-invasive ventilation (NIV) and invasive mechanical ventilation (IMV) are most important interventions for patients with severe CAP associated with respiratory failure. We analysed utilization trends and predictors of non-invasive and invasive ventilation in patients hospitalized with CAP. METHODS Nationwide Inpatient Sample and Healthcare Cost and Utilization Project data for years 2008-2017 were analysed. Adult hospitalizations due to CAP were identified by previously validated International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) and International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes. We then utilized the Cochran-Armitage trend test and multivariate survey logistic regression models to analyse temporal incidence trends, predictors, and outcomes. We used SAS 9.4 software (SAS Institute Inc., Cary, NC, USA) for analysing data. RESULTS Out of a total of 8,385,861 hospitalizations due to CAP, ventilation assistance was required in 552,395 (6.6%). The overall ventilation use increased slightly; however, IMV utilization decreased, while NIV utilization increased. In multivariable regression analysis, males, Asian/others and weekend admissions were associated with higher odds of any ventilation utilization. Concurrent diagnoses of septicemia, congestive heart failure, alcoholism, chronic lung diseases, pulmonary circulatory diseases, diabetes mellitus, obesity and cancer were associated with increased odds of requiring ventilation assistance. Ventilation requirement was associated with high odds of in-hospital mortality and discharge to facility. CONCLUSION The use of NIV among CAP patients has increased while IMV use has decreased over the years. We observed numerous factors linked with a higher use of ventilation support. The requirement of ventilation support is also associated with very high chances of mortality and morbidity.

Abstract
Background Community-acquired pneumonia (CAP) is a leading cause of hospitalization worldwide. Bed rest with low levels of physical activity is common during periods of hospitalization and leads to functional decline as well as increased risk of complications. The aim of this study is to assess the effect of supervised physical training during hospitalization with CAP compared with standard usual care for CAP on length of hospital stay, risk of readmission, mortality risk, physical capacity, muscle and fat mass, muscle strength, metabolic function, systemic inflammation, health-related quality of life, and physical activity level. Methods This study is a randomized controlled trial with three parallel experimental arms. Based on a sample size calculation, a total of 210 patients admitted with CAP at Nordsjællands Hospital, Hillerød, Denmark, will be recruited. Patients will be randomly allocated (1:1:1) to either (1) standard usual care, (2) standard usual care combined with in-bed cycling, or (3) standard usual care combined with exercises from a booklet. The primary outcome is differences in length of hospital stay between groups, with secondary outcomes being differences between groups in time to (1) 90-day readmission and (2) 180-day mortality. Further secondary outcomes are differences in changes from baseline between groups in (3) lean mass, (4) fat mass, (5) fat-free mass, (6) physical capacity, (7) health-related quality of life, (8) systemic inflammation, and (9) physical activity level after discharge. Data on length of hospital stay, readmission, and mortality will be collected from patient files, while total lean, fat, and fat-free mass will be quantitated by dual-energy x-ray absorptiometry and bioelectrical impedance analysis. Physical function will be assessed using grip strength, 30-s chair stand tests, and Barthel Index-100. Health-related quality of life will be assessed with the EQ-5D-5L questionnaire. Systemic inflammation will be assessed in blood samples, while accelerometers are used for measuring physical activity. Discussion If a simple physical training program appears to diminish the impact of critical illness and hospitalization on clinical outcome, mobility, and health-related quality of life, it may lead to novel therapeutic approaches in the treatment of patients hospitalized with CAP.

Characteristics and Epidemiology of Discharged Pneumonia Patients in South Korea Using the Korean National Hospital Discharge In-Depth Injury Survey Data from 2006 to 2017. Infect Dis Rep 2021; 13:730-741. [PMID: 34449656 PMCID: PMC8395938 DOI: 10.3390/idr13030068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Revised: 08/16/2021] [Accepted: 08/17/2021] [Indexed: 12/03/2022] Open
Abstract
Despite the use of vaccines and various antibiotics, approximately 30% of the South Korean population is treated for pneumonia each year, and the number of deaths from pneumonia continues to increase. The present study used information on discharged patients in South Korea to investigate the number and characteristics of discharged pneumonia patients across 12 years. Using the Korean National Hospital Discharge In-Depth Injury Survey data, information on discharged patients from 2006 to 2017 were collected. The number of discharged pneumonia patients for each year and their age group was assessed, and the Charlson Comorbidity Index was used to assess the risk of comorbidities in these patients. The number of discharged pneumonia patients varied every year in South Korea. In particular, the total number of patients increased substantially in 2011, with a large increase in the number of infants and children. In addition, the number of discharged pneumonia patients increased in the elderly group compared to the other age groups. Moreover, a recent increase in the severity of comorbidities in pneumonia patients was noted. Given the continued increase in the number of elderly patients with pneumonia, chronic diseases, such as hypertension and diabetes, should be managed first in the elderly. Moreover, appropriate treatment methods should be selected based on the presence of comorbidities.

Abstract
INTRODUCTION The prevalence of congenital heart disease (CHD) in adults is rising necessitating a greater understanding of acquired diseases such as community-acquired pneumonia, which remains a leading cause of age-related mortality and morbidity in the general population. We hypothesise that the CHD population, given cardiopulmonary mechanics and altered immune function, bears a uniquely high risk for pneumonia-related hospitalisations and mortality. METHODS A countrywide cohort study was performed to calculate the relative risk and cumulative incidence of pneumonia hospitalisations and resultant 30-day mortality amongst the adult CHD population, matched 1:10 with non-CHD persons by gender, age, and adjusted for comorbidities. Cox proportional hazard regression quantified the impact of CHD severity and extracardiac defects. RESULTS The CHD cohort includes 17,162 adults. The majority demonstrate mild/moderate CHD complexity. The cumulative incidence of pneumonia hospitalisation was higher for adults with CHD (hazard ratio 1.90; 95% confidence interval: 1.74-2.06) than the comparison cohort. This risk was increased for those with extracardiac defects or a syndrome (hazard ratio: 4.34; 95% confidence interval: 3.39-5.54). Additionally, CHD individuals with severe/univentricular subtypes demonstrate a heightened risk compared to the non-CHD cohort (hazard ratio: 2.35; 95% confidence interval: 1.94-2.84), as well as compared to those with mild/moderate CHD (hazard ratio: 1.28; 95% confidence interval: 1.07-1.53). In addition, pneumonia hospitalisation mortality was elevated above the comparison population with a 30-day mortality rate ratio of 1.31 (95% confidence interval: 1.00-1.73). CONCLUSION Adults with CHD are at elevated risk of pneumonia hospitalisations and pneumonia-associated mortality. This risk is further elevated in those with severe CHD and extracardiac defects.

Abstract
OBJECTIVE To examine the association between body mass index (BMI) and mortality after hospitalization for infection because obesity is associated with increased energy reserves that may protect against death from severe infections. PATIENTS AND METHODS Of 76,044 patients admitted with a primary infection diagnosis from January 1, 2011, to September 30, 2015, in Central Denmark, we examined a subgroup of 35,406 patients with a known BMI. We compared the 90-day death risk among patients with underweight, overweight, or obesity with a reference cohort of normal-weight patients. We also examined the impact of comorbid conditions, including cancer, tobacco smoking, and recent weight changes, on the associations and adjusted for other potential confounding factors. RESULTS The 90-day mortality after hospital admission was 9.8% (3479 of 35,406) for any infection, 10.5% (466 of 4425) for urinary tract infection, 17.3% (1536 of 8855) for pneumonia, 24.9% (986 of 3964) for sepsis, and 6.2% (114 of 1831) for skin infection. The 90-day adjusted hazard ratio (aHR) for death was substantially increased in patients with underweight (aHR, 1.75; 95% CI, 1.58 to 1.94) compared with normal-weight patients. In contrast, mortality aHRs were decreased in patients with overweight (aHR, 0.64; 95% CI; 0.58 to 0.69) and obesity (aHR, 0.55; 95% CI; 0.49 to 0.62). Mortality reductions with overweight and obesity were consistent for all major infection types and remained robust independent of recent weight changes, smoking status, or comorbid conditions. Mortality was highest in patients without an apparent reason for their underweight (smoking/known disease), suggesting a role of undiagnosed comorbid conditions. CONCLUSION We found evidence that higher BMI (overweight and obesity) is associated with improved survival following acute hospitalization for infection, whereas underweight increases the risk for death.

Clin Microbiol Infect 2020; 27:406-412. [PMID: 32896655 DOI: 10.1016/j.cmi.2020.08.037] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 08/18/2020] [Accepted: 08/24/2020] [Indexed: 01/21/2023]
Abstract
OBJECTIVES Community-acquired pneumonia (CAP) is a frequently occurring disease linked to high mortality and morbidity. Previous studies indicated that the administration of antibiotics within 4 hrs of admission can improve key patient outcomes associated with CAP, such as mortality and time to clinical stability. However, the results have been heterogeneous and may not be applicable to all healthcare settings. Therefore, we designed a cohort study to estimate the impact of timely antibiotic administration on outcomes in patients admitted with CAP. METHODS The impact of antibiotic administration within 4 hrs of admission and other covariates were estimated for 30-day mortality, stability within 72 hrs, 30-day readmission and time to discharge, using multivariable regression models. Sensitivity analyses were performed on a subset of patients with the most severe CAP and a propensity score matched cohort. RESULTS In total, 2264 patients were included. Of these, 273 (12.1%) died within 30 days of admission, 1277 (56.4%) were alive and stable within 72 hrs and 334 (14.8%) were discharged alive and readmitted within 30 days. Median length of hospital stay was 5 days (interquartile range 3-8). In all models, the administration of antibiotics within 4 hrs of admission had no significant effect on the outcomes. The adjusted odds ratios (OR) derived from the multivariable models for 30-day mortality, stability within 72 hrs and 30-day readmission were 1.01 (95% confidence interval (CI) 0.76; 1.33), 0.88 (95% CI 0.74; 1.05) and 1.05 (95% CI 0.82; 1.34). The adjusted hazard ratio (HR) for time to discharge was 1.00 (95% CI 0.91; 1.10). DISCUSSION A strict 4-hr threshold for antibiotic administration in all patients admitted with CAP is not reasonable. Instead, our results suggested that patients should be triaged and prioritized according to age, comorbidities, clinical condition and pneumonia severity.

Hospital admissions for community-acquired, ventilator-associated and nonventilator hospital-acquired pneumonia in COPD patients in Spain (2016-2017). Eur J Intern Med 2020; 79:93-100. [PMID: 32616338 DOI: 10.1016/j.ejim.2020.06.028] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Revised: 06/22/2020] [Accepted: 06/25/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND To examine the incidence, characteristics and outcomes of community-acquired pneumonia (CAP), ventilator-associated pneumonia (VAP) and nonventilator hospital-acquired pneumonia (NV-HAP) in patients with or without COPD; compare in-hospital outcomes; and identify factors associated with in-hospital mortality (IHM) for pneumonia. METHODS We carried out a retrospective observational study using the hospital discharge records from 2016-17 of the Spanish National Health System. Propensity score matching was used for data analysis. RESULTS We found 245,905 patients (≥40 years) with pneumonia; we identified CAP in 228,139 patients (19.85% with COPD), VAP in 2,771 patients (8.55% with COPD) and NV-HAP in 14,995 patients (14.17% with COPD). The incidence for the three types of pneumonia was higher in COPD patients (CAP: incidence rate ratio (IRR) 2.23, 95% CI 2.21-2.26; VAP: IRR 1.25, 95% CI 1.08-1.42; and NV-HAP: IRR 1.55, 95% CI 1.48-1.63). The IHM for CAP was 10.35% in COPD patients and 12.91% in the controls (p<0.001). In patients with VAP and NV-HAP, IHM was not significantly different between those with and without COPD (43.88% vs. 41.77%;p=0.643 and 29.21% vs. 30.57%;p=0.331, respectively). Factors associated with IHM for all types of pneumonia analyzed in COPD patients were older age and receiving dialysis. CONCLUSIONS The incidence of hospitalizations for all types of pneumonia was significantly higher in COPD patients than in the non-COPD population. In contrast, IHM was significantly lower among COPD patients with CAP than among matched non-COPD patients. Higher mortality rates in COPD patients with any pneumonia type were associated with increasing age and receiving dialysis.

Abstract
Background To investigate the use of do-not-resuscitate (DNR) orders in patients hospitalized with community-acquired pneumonia (CAP) and the association with mortality. Methods We assembled a cohort of 1317 adults hospitalized with radiographically confirmed CAP in three Danish hospitals. Patients were grouped into no DNR order, early DNR order (≤48 h after admission), and late DNR order (> 48 h after admission). We tested for associations between a DNR order and mortality using a cox proportional hazard model adjusted for patient and disease related factors. Results Among 1317 patients 177 (13%) patients received a DNR order: 107 (8%) early and 70 (5%) late, during admission. Patients with a DNR order were older (82 years vs. 70 years, p < 0.001), more frequently nursing home residents (41% vs. 6%, p < 0.001) and had more comorbidities (one or more comorbidities: 73% vs. 59%, p < 0.001). The 30-day mortality was 62% and 4% in patients with and without a DNR order, respectively. DNR orders were associated with increased risk of 30-day mortality after adjustment for age, nursing home residency and comorbidities. The association was modified by the CURB-65 score Hazard ratio (HR) 39.3 (95% CI 13.9–110.6), HR 24.0 (95% CI 11.9–48,3) and HR 9.4 (95% CI: 4.7–18.6) for CURB-65 score 0–1, 2 and 3–5, respectively. Conclusion In this representative Danish cohort, 13% of patients hospitalized with CAP received a DNR order. DNR orders were associated with higher mortality after adjustment for clinical risk factors. Thus, we encourage researcher to take DNR orders into account as potential confounder when reporting CAP associated mortality.

Abstract
Background Community-acquired pneumonia (CAP) is one of the leading causes of healthcare utilisation and death worldwide. Treatment according to evidence-based clinical guidelines can reduce mortality, antibiotic exposure and length of hospital stay related to CAP. Local problem Several studies, including a pilot study from one of our sites, indicate that physicians show a low grade of guideline adherence when managing patients with CAP. Methods To improve the guideline-based treatment of patients with CAP admitted to hospital, we designed a quality improvement study. Four process indicators were combined in a CAP care bundle: chest X-ray, CURB-65 severity score, lower respiratory tract samples and antibiotics within 8 hours from admission. After a 4-month baseline period, we applied multiple interventions at three hospitals during 8 months. Progression in our process indicators was measured continuously and compared with a control site without interventions. After the 8-month intervention period, we continued with a 4-month follow-up period to assess the sustainability of the improvements. Results The care bundle utilisation rate within 8 hours increased from 11% at baseline to 41% in the follow-up period at the intervention sites, whereas it remained below 3% at the control site. The most considerable improvements have been observed regarding documentation of CURB-65 (34% at baseline, 68% at follow-up) and the collection of lower respiratory tract samples (43% at baseline, 63% at follow-up). Conclusion Our study has demonstrated poor adherence to CAP guidelines at all sites at baseline. After implementing multiple tailored interventions, guideline adherence increased substantially. In conclusion, we recommend that CAP guidelines should be actively adapted in order to be followed in a daily routine.

Abstract
Objective Little is known about the prognosis of infections in patients with ankylosing spondylitis (AS) compared with patients without AS. The purpose of this study was to examine whether AS is associated with poorer outcomes in patients who are hospitalised with pneumonia. Methods In a population-based cohort study including patients with hospitalised pneumonia with and without AS, we compared 90-day rates of mortality, all-cause readmission (90 days post-discharge) and pulmonary complications including pulmonary embolism, empyema and pulmonary abscess. We used Cox regression analyses to compute crude and adjusted HRs while adjusting for sex, age and level of comorbidity. Results A total of 387 796 patients (median age 71 years) were hospitalised for pneumonia in Denmark between 1997 and 2017. Among these, 842 (0.2%) had AS (median age 65 years). The 90-day mortality was 12.5% in patients with AS and 15.5% in patients with non-AS pneumonia, with crude and adjusted 90-day HRs of 0.79 (95% CI 0.66 to 0.96) and 0.95 (95% CI 0.79 to 1.16), respectively. The 90-day post-discharge readmission rate was 27.3% in patients with AS and 25.4% in patients without AS, with a corresponding adjusted readmission HR of 1.12 (95% CI 0.98 to 1.27). Relative risk of pulmonary complications among patients with AS compared with patients without AS decreased over the study period, with adjusted HRs of 1.63 (95% CI 0.82 to 3.27) in 1997–2006 falling to 0.62 (95% CI 0.31 to 1.23) in 2007–2017. Conclusions AS is not associated with increased mortality following hospitalisation for pneumonia. Furthermore, no increased risk of readmission or pulmonary complications in patients with AS was detected in recent study years.

Abstract
The use of psychotropic drugs (antipsychotics, benzodiazepines and benzodiazepine-related drugs, and antidepressants) is common, with a prevalence estimates range of 19-29% among community dwelling older adults. These drugs are often prescribed for off-label use, including neuropsychiatric symptoms. The older adult population also has high rates of pneumonia and some of these cases may be associated with adverse drug events. In this narrative review, we summarize the findings from current observational studies on the association between psychotropic drug use and pneumonia in older adults. In addition to studies assessing the use of psychotropics, we included antiepileptic drugs, as they are also central nervous system-acting drugs, whose use is becoming more common in the aging population. The use of antipsychotics, benzodiazepine, and benzodiazepine-related drugs are associated with increased risk of pneumonia in older adults (≥ 65 years of age), and these findings are not limited to this age group. Minimal and conflicting evidence has been reported on the association between antidepressant drug use and pneumonia, but differences between study populations make it difficult to compare findings. Studies regarding antiepileptic drug use and risk of pneumonia in older persons are lacking, although an increased risk of pneumonia in antiepileptic drug users compared with non-users in persons with Alzheimer's disease has been reported. Tools such as the American Geriatric Society Beers Criteria and the STOPP/START criteria for potentially inappropriate medications aids prescribers to avoid these drugs in order to reduce the risk of adverse drug events. However, risk of pneumonia is not mentioned in the current criteria and more research on this topic is needed, especially in vulnerable populations, such as persons with dementia.

Abstract
BACKGROUND Immobility is common and associated with adverse outcomes in hospitalized patients, especially older people. However, the factors contributing to mortality in bedridden patients are not well known. This study aimed to estimate short-term mortality and analyze risk factors that affect the prognosis of bedridden patients. METHODS This was a multicenter study in China involving 23,738 patients admitted to 25 hospitals between November 2015 and June 2016. All-cause mortality was recorded for 90 days after enrollment regardless of whether death occurred before or after discharge. Socio-demographic and clinical information was obtained from an electronic database. Univariate and multivariate Cox regression analysis was used to identify factors associated with mortality. RESULTS In total, 23,738 hospitalized bedridden patients, there were 1,114 (4.7%) observed deaths. The overall mortality rate was therefore 4.7%. Of these, 318 (1.4%) died while hospitalized and 796 (3.4%) after discharge. The univariate Cox regression analysis showed that variables significantly associated with 90-day mortality included total time spent bedridden, urinary tract infection and pulmonary infection (p<0.05). The multivariate Cox regression analysis showed that the independent risk factors for death were age (adjusted hazard ratio [aHR] 1.006, 95% CI 1.000-1.011), and pulmonary infection (aHR 1.439, 95% CI 1.266-1.635). The hazard ratios for mortality were reduced with urinary tract infection and more time spent bedridden. CONCLUSIONS The mortality after discharge was significantly higher than mortality in hospital. The factors affecting short-term mortality in bedridden patients included age, time spent bedridden, urinary tract infection and pulmonary infection. This suggests these factors may be potential predictors of mortality in bedridden patients. It is essential for medical staff to improve health education of patients and family members, pay more attention to follow up after discharge and meet care needs at home.

Abstract
BACKGROUND There is limited evidence on the impact of pneumococcal conjugate vaccine childhood immunization programmes (PCV-CIP) on community-acquired pneumonia (CAP) in individuals with underlying diseases. METHODS A nationwide cohort study using Swedish health registers to assess the incidence of hospitalization with all-cause (AC-CAP) and pneumococcal or lobar (PL-CAP) CAP between 2005 and 2015, in relation to PCV-CIP introduction in 2007-09. RESULTS In total, 303 691 episodes of AC-CAP occurred, of which 14 225 were PL-CAP. Comparing before (2005-06) with after (2014-15) PCV-CIP, relative incidence reductions were 36% (95% Confidence Interval 32-40), 20% (14-25) and 16% (11-22) of AC-CAP for age groups < 2, 2-4 and 5-17 years, respectively, with similar reductions in young children with and without comorbidities. The reductions were more pronounced for PL-CAP. In the age groups 40-64, 65-74, 75-84 and ≥85 years there were relative increases of 11% (8-14), 18% (15-22), 15% (12-17) and 30% (27-34) of AC-CAP, respectively, but these increases were attenuated after adjustment for admittance practices using four control conditions. In adults with comorbidities, there was an increase in incidence of AC-CAP, and PL-CAP, in contrast to adults without reported underlying diseases where the incidence was stable or diminished for some age groups. Over the study period, there was an increased proportion of pneumonia patients with underlying diseases in all ages. CONCLUSION This emphasizes that direct preventive interventions should be targeted towards individuals with underlying diseases. Future studies should investigate reasons for the observed increased risk in adults with comorbidities, for example due to pneumococcal nonvaccine serotypes, or other pathogens, preferentially affecting subjects with underlying diseases.

Monitoring of community-acquired pneumonia hospitalisations before the introduction of pneumococcal conjugate vaccine into Polish National Immunisation Programme (2009-2016): A nationwide retrospective database analysis. Vaccine 2019; 38:194-201. [PMID: 31653527 DOI: 10.1016/j.vaccine.2019.10.031] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Revised: 10/09/2019] [Accepted: 10/10/2019] [Indexed: 01/25/2023]
Abstract
PURPOSE Community-acquired pneumonia (CAP) is a common infection with significant morbidity and mortality. In January 2017, Poland introduced pneumococcal conjugate vaccine (PCV) into their national immunisation programme to protect children against invasive pneumococcal disease. This study was designed to investigate pneumonia-related hospitalisation rates and trends from 2009 to 2016 prior to the introduction of nationally funded PCV vaccination. METHODS Using national public statistic data available from the National Institute of Public Health - National Institute of Hygiene, annual hospitalisation rates for pneumonia were analysed, categorised by aetiology and age (<2, 2-3, 4-5, 6-19, 20-59, 60+ years). Trends over time were assessed, as well as in-hospital mortality. RESULTS The overall hospitalisation rate due to pneumonia varied between 325.9 and 372.2/100,000 population. Higher rates of hospitalisation were seen in older adults and children ≤5 years. Trends were observed when analysing hospitalisations by pneumonia aetiology within age groups: between 2009 and 2016, Streptococcus pneumoniae hospitalisations significantly increased for children aged <2, 2-3, and 4-5 years, from 5.3 to 12.4, 5.2 to 8.2, and 1.9 to 4.6/100,000 population respectively. Whereas hospitalisations due to Haemophilus influenzae pneumonia decreased significantly from 7.8 to 1.8 and 4.8 to 1.9/100,000 children aged <2 and 2-3 years respectively. The numbers of in-hospital deaths increased from 5578 in 2009 to 8149 in 2016, with >85% of deaths in the 60+ age group. CONCLUSIONS This is the first national study of pneumonia hospitalisations in Poland, providing the baseline data from which to investigate the impact of the change in vaccination policy on pneumonia hospitalisations in Poland.

Abstract
We aimed to examine trends in the incidence of treated infections following hip fracture surgery in Denmark from 2005 to 2016. We conducted a nationwide cohort study using individual-level linked data from Danish population-based registries. We calculated cumulative incidence considering death as competing risk and, based on the pseudo-observation method, risk ratios (RRs) with 95% confidence interval (CI) using the period 2005-2006 as a reference. RRs were adjusted for age, sex, and comorbidity. A total of 74,771 patients aged 65 years or older with first-time hip fracture surgery were included. The risk of postoperative (at 15, 30, 90, and 365 days) infections increased during 2005-2016. The 30-day cumulative incidence of all hospital-treated infections increased from 10.8% (95% CI, 10.2% to 11.3%) in 2005-2006 to 14.3% (95% CI, 13.7% to 15.0%) in 2015-2016 (adjusted RR 1.32; 95% CI, 1.23 to 1.42). Adjusted RR for 30-day hospital-treated pneumonia was 1.70 (95% CI, 1.49 to 1.92). The 30-day cumulative incidence of redeeming community-based antibiotic prescriptions increased from 17.5% (95% CI, 16.8% to 18.2%) in 2005-2006 to 27.1% (95% CI, 26.3% to 27.9%) in 2015-2016 (adjusted RR 1.54; 95% CI, 1.47 to 1.62). The largest increase was observed for broad-spectrum antibiotic use (adjusted RR 1.79; 95% CI, 1.68 to 1.90). During 2005-2016, risk of infections was substantially higher in hip fracture patients than in the general population. The risk of hospital-treated pneumonia and antibiotic prescriptions increased more over time among hip fracture patients. We found increased risks of postoperative treated infections following hip fracture surgery during the 12-year study period, which could not entirely be explained by similar infection trends in the general population. Given the high mortality following infections in the elderly, further research is needed to identify patients at increased risk to target preventive treatment and potentially reduce complications and mortality in hip fracture patients. © 2018 American Society for Bone and Mineral Research.

Abstract
BACKGROUND AND AIMS The aim of the study was to ascertain changes in the incidence, etiology, treatment, and outcomes of pleural infections over a decade in a Finnish University Hospital. MATERIALS AND METHODS All patients treated for pleural infections in Tampere University Hospital during 2000-2008 and 2012-2016 were included. The incidence rates and the epidemiologic data and medical history of patients, etiology of infection, and treatment trends and outcomes were compared between the cohorts. RESULTS The incidence of pleural infections increased from 4.4 during 2000-2008 to 9.9 during 2012-2016 per 100.000 patient-years, p < 0.001. The patients in the latter group were older, 63 versus 57 years, p = 0.001, and the prevalence of chronic lung disease, hypertension, heart failure, dyslipidemia, and immunosuppressive medication were higher. The causes of infection remained similar and pneumonia accounted for 70% of all cases. The identification rate of the microbe pathogens increased from 49% to 64%, p = 0.002, while the distribution of identified pathogens was unchanged. More patients in the latter cohort were treated operatively, 88.3% versus 80.9%, p = 0.005, and, in these, the proportion of thoracoscopic surgery was higher, 57.4% versus 8.0%, p < 0.001, and the delay to surgery shorter, 5 versus 7 days, p < 0.001. Radiologic outcomes were similar. The 30-day mortality rate was 3.1% during 2000-2008 and 5.1% during 2012-2016, p = 0.293. CONCLUSION The overall incidence of pleural infections has increased significantly while the causes of pleural infections and the distribution of pathogens remain unchanged. Contemporary patients are older with higher prevalence of comorbidities and more frequently undergo thoracoscopic surgery.

Abstract
Up-to-date data on the burden of disease are important to identify patients with unmet needs and to optimize healthcare resources. We aimed to characterize the burden of pneumonia hospitalizations in Hong Kong and inform targeted healthcare policies for pneumonia control in the era of global aging. This was a population-based study using a territory-wide administrative electronic health record system that covers all public hospitals of Hong Kong. Patients admitted to public hospitals, from 2011 to 2015, with a diagnosis of pneumonia at discharge were identified based on the International Classification of Diseases-Ninth Revision-Clinical Modification Codes (480-486 and 487.0). Incidence, inpatient case-fatality, all-cause fatality, 28-day readmission, hospital length of stay, and healthcare costs were assessed for seven age strata. We identified 323,992 patients (median age 80 years, 44.4% female) with hospitalized pneumonia (organism unspecified 84.2%; bacterial pneumonia 12.3%; viral pneumonia 2.5%; others 1.0%). Annual incidence was 955.1 per 100,000 population, with a 10.6% decrease from 2011 to 2015. Case-fatality, all-cause fatality, and 28-days readmission risks were 13.8, 21.6, and 19.5%, respectively. The average hospital length of stay was 14.1 days with corresponding direct costs of $9348 USD per episode in the monetary value of 2015. Individuals aged ≥ 65 years accounted for over 75% of pneumonia-related hospitalizations, 90% of deaths, and the majority of healthcare costs. Hospitalized pneumonia represents a considerable health and economic burden in Hong Kong, especially in older adults. The study provides a population-level baseline estimate for further cost-effective evaluation of targeted strategies for pneumonia control.

Abstract
Background Diabetes mellitus is an important risk factor for community-acquired pneumonia, whereas the prevalence of undiagnosed diabetes mellitus and prediabetes in patients with community-acquired pneumonia is largely unknown. We aimed to determine the prevalence of prediabetes, undiagnosed diabetes mellitus, and risk factors associated with undiagnosed diabetes mellitus in a large European community-acquired pneumonia cohort. Methods This was a multicenter prospective cohort study of hospitals and private practices in Germany and Austria encompassing 1961 adults with community-acquired pneumonia included in the German Community-Acquired Pneumonia Competence Network (CAPNETZ) study between 2007 and 2014. The prevalence of undiagnosed diabetes mellitus and prediabetes was estimated based on hemoglobin A1c measurements. Logistic regression was used to assess risk factors for undiagnosed diabetes mellitus. Results Fifteen percent of patients had known diabetes mellitus. Among patients without known diabetes mellitus, 5.0% had undiagnosed diabetes mellitus and 37.5% had prediabetes. Male sex (odds ratio [OR], 2.45 [95% confidence interval {CI}, 1.35-4.45]), body mass index ≥25 kg/m2 (OR, 2.64 [95% CI, 1.48-4.72]), and hyperglycemia at admission (6-11 mM: OR, 2.93 [95% CI, 1.54-5.60] and ≥11 mM: OR, 44.76 [95% CI, 17.58-113.98]) were associated with undiagnosed diabetes mellitus. Patients with undiagnosed diabetes mellitus had a higher 180-day mortality rate compared to patients without diabetes mellitus (12.1% vs 3.8%, respectively; P = .001). Conclusions Undiagnosed diabetes mellitus was prevalent among community-acquired pneumonia. Male sex, overweight, and hyperglycemia at admission were associated with undiagnosed diabetes mellitus. The long-term mortality among patients with undiagnosed diabetes mellitus was high compared to patients without diabetes mellitus.

Abstract
AIM To examine trends in incidence and outcomes of community-acquired pneumonia (CAP) hospitalizations among patients with or without COPD in Spain (2004-2013). METHODS We used national hospital discharge data to select all hospital admissions for CAP. Incidence was calculated overall and according to the presence or absence of COPD. RESULTS We identified 901,136 hospital admissions for CAP (32.25% with COPD). Incidence of hospitalizations of CAP increased significantly over time among patients with and without COPD, but it was higher among people with COPD for all years analyzed. S. pneumoniae decreased over time for both groups. Time trend analyses showed significant decreases in mortality during admission for CAP for patients with and without COPD. Factor independently associated with higher mortality in both groups included: male sex, older age, higher comorbidity, isolation of S. aureus or P. aeruginosa, use of mechanical ventilation, and readmission. The presence of COPD was associated with a lower in-hospital mortality (IHM) (OR: 0.58, 95%CI 0.57-0.59). CONCLUSIONS The incidence of hospitalizations for CAP increased over time in patients with and without COPD, being higher in the COPD population for all years analyzed. IHM decreased over time in both groups. There were no differences in mortality between COPD and non-COPD patients.

Abstract
Hyperglycaemia is common in patients with community-acquired pneumonia (CAP) and is a predictor of severe outcomes. Data are scarce regarding whether this association is affected by diabetes mellitus (DM) and also regarding its importance for severe outcomes in hospital. We determined the impact of blood glucose on severe outcomes of CAP in hospital. We studied 1318 adult CAP patients hospitalised at three Danish hospitals. The association between blood glucose and DM status and severe clinical outcome (admission to an intensive care unit (ICU) and/or in-hospital mortality) was assessed by logistic regression. Models were adjusted for CURB-65 score and comorbidities. 12% of patients had DM. In patients without DM an increase in admission blood glucose was associated with risk for ICU admittance (OR 1.25, 95% CI 1.13-1.39), but not significantly associated with in-hospital mortality (OR 1.10, 95% CI 0.99-1.23). In patients with DM an increase in admission blood glucose was not associated with ICU admittance (OR 1.05, 95% CI 1.00-1.12) or in-hospital mortality (OR 1.05, 95% CI 0.99-1.12). An increase in admission blood glucose (only in patients without DM) was associated with a higher risk for ICU admittance and a trend towards higher in-hospital mortality. DM was not associated with a more severe outcome of CAP.

Abstract
AIM To describe trends in the incidence and outcomes of community-acquired pneumonia (CAP) hospitalizations in Spain (2004-2013). METHODS We used national hospital discharge data to select all hospital admissions for CAP as primary diagnosis. We analyzed incidence, Charlson comorbidity index (CCI), diagnostic and therapeutic procedures, pathogens, length of hospital stay (LOHS), in-hospital mortality (IHM) and readmission. RESULTS We identified 959,465 admissions for CAP. Incidence rates of CAP increased significantly over time (from 142.4 in 2004 to 163.87 cases per 100,000 inhabitants in 2013). Time trend analyses showed significant increases in the number of comorbidities and the use of CAT of thorax, red cell transfusion, non-invasive mechanical ventilation and readmissions (all p values<0.05). S. pneumoniae was the most frequent causative agent, but its isolation decreased over time. Overall median of LOHS was 7days and it did not change significantly during the study period. Time trend analyses also showed significant decreases in mortality during admission for CAP. Factor associated with higher IHM included: older age, higher CCI, S. aureus isolated, use of red cell transfusion or mechanical ventilation and readmission. CONCLUSIONS The incidence and mortality of CAP have changed in Spain from 2004 to 2013. Although there was an increased incidence of hospitalization for this disease over time, we saw a significant reduction in IHM.

Abstract
Background Pneumonia and urinary tract infections (UTIs) increase morbidity and mortality. There is little epidemiological evidence from large population-based studies on risk factors for these infections and subsequent mortality in total hip arthroplasty (THA) patients. Aim To examine the risk factors of postoperative pneumonia and UTI after THA and their impact on survival. Patients and methods We used the Danish Hip Arthroplasty Register to identify THAs due to osteoarthritis registered from 2000 to 2013. We collected data about comorbidities, mortality and infections in relation to primary hospitalization and potential predictive variables from administrative databases. Regression models were used to estimate associations between potential risk factors and infection, and subsequently, between infection and mortality. Results In total 84,812 THAs were included. The cumulative incidence of pneumonia and UTI within 7 days of the primary procedure were 0.21 (95% confidence interval [CI]: 0.18–0.25) and 0.29 (95% CI: 0.26–0.33), respectively. Patient-related risk factors for infection were being 80 years or older, gender and a comorbidity burden at time of surgery. The hazard ratio (HR) of dying within 90 days of the primary THA was 10.67 (95% CI: 5.79–19.57) compared to patients without pneumonia. For patients with UTIs, the HR was 1.64 (95% CI: 0.41–6.59) compared to those without a UTI. Conclusion Pneumonia was associated with an increased short-term risk of dying, despite adjustment for coexisting comorbidity and other potential confounders. Age, gender and comorbidity were the most important risk factors for pneumonia and UTIs. Individual initiatives to reduce the risk of pneumonia in select patient groups may be essential to the effort to optimize outcomes after a THA.

Abstract
OBJECTIVES To describe trends in the incidence and outcomes of community-acquired pneumonia (CAP) hospitalisations among patients with or without diabetes in Spain (2004-2013). DESIGN Retrospective, observational study using the Spanish National Hospital Discharge Database (Conjunto Mínimo Básico de Datos (CMBD)). SETTING Spain. PARTICIPANTS We used national hospital discharge data to select all hospital admissions for CAP. MAIN OUTCOME MEASURES Incidence was calculated overall and stratified by diabetes status: type 2 diabetes mellitus (T2DM) and no diabetes. RESULTS We identified 901 136 admissions for CAP (24.8% with T2DM). Incidence rates of CAP increased significantly in patients with T2DM over time. The incidence was higher among people with T2DM for all time periods. Patients with T2DM were older and had higher comorbidity index than non-diabetics. Streptococcus pneumoniae decreased over time for both groups. Time trend analyses showed significant decreases in mortality during admission for CAP for patients with and without T2DM. Factors associated with higher mortality in both groups included: older age, higher comorbidity, mechanical ventilation, red cell transfusion, readmission and Staphylococcus aureus detection. Diabetes was associated with a lower in-hospital mortality (OR 0.92, 95% CI 0.91 to 0.94) after a CAP hospitalisation. CONCLUSIONS CAP incidence rates were higher and increased over time at a higher rate among patients with T2DM. Mortality decreased over time in all groups. The presence of diabetes is not a risk factor for death during admission for CAP.

Abstract
BACKGROUND Community-acquired pneumonia (CAP) is a major cause of mortality and morbidity in many countries but few recent large-scale studies have examined trends in its incidence. METHODS Incidence of CAP leading to hospitalisation in one UK region (Oxfordshire) was calculated over calendar time using routinely collected diagnostic codes, and modelled using piecewise-linear Poisson regression. Further models considered other related diagnoses, typical administrative outcomes, and blood and microbiology test results at admission to determine whether CAP trends could be explained by changes in case-mix, coding practices or admission procedures. RESULTS CAP increased by 4.2%/year (95% CI 3.6 to 4.8) from 1998 to 2008, and subsequently much faster at 8.8%/year (95% CI 7.8 to 9.7) from 2009 to 2014. Pneumonia-related conditions also increased significantly over this period. Length of stay and 30-day mortality decreased slightly in later years, but the proportions with abnormal neutrophils, urea and C reactive protein (CRP) did not change (p>0.2). The proportion with severely abnormal CRP (>100 mg/L) decreased slightly in later years. Trends were similar in all age groups. Streptococcus pneumoniae was the most common causative organism found; however other organisms, particularly Enterobacteriaceae, increased in incidence over the study period (p<0.001). CONCLUSIONS Hospitalisations for CAP have been increasing rapidly in Oxfordshire, particularly since 2008. There is little evidence that this is due only to changes in pneumonia coding, an ageing population or patients with substantially less severe disease being admitted more frequently. Healthcare planning to address potential further increases in admissions and consequent antibiotic prescribing should be a priority.

Abstract
Background Pneumonia is a frequent lung infection and a serious illness, which is often diagnosed among patients hospitalized with acute exacerbations of COPD. The aim of this study was to estimate the attributable costs due to pneumonia among patients hospitalized with pneumonia compared to a matched general population control group without pneumonia hospitalization. Methods This study includes citizens older than 18 years from three municipalities (n=142,344). Based on national registers and municipal data, the health and social care costs of pneumonia in the second half of 2013 are estimated and compared with propensity score-matched population controls. Results The average health care costs of 383 patients hospitalized with pneumonia in the second half of 2013 were US$34,561 per patient. Among pneumonia patients with COPD, the costs were US$35,022. The attributable costs of patients with pneumonia compared to the population control group for the 6-month period were US$24,155 per case. Overall, the attributable costs for the 383 pneumonia cases amounted to US$9.25 million. Subgroup analyses showed that costs increased with age. The attributable costs due to pneumonia were highest among the 18–59-year-old and the 70–79-year-old patients. This difference is likely to reflect an increased risk of mortality among the pneumonia patients. Men have higher costs than women in the pneumonia group. Conclusion The costs of pneumonia are considerable. In three Danish municipalities, the attributable costs due to pneumonia were US$24,155 per case or US$64,992 per 1,000 inhabitants in the second half of 2013. Similar high health care and social care costs were found for pneumonia patients with COPD – the largest group having pneumonia episodes. The municipalities are responsible for 49% of the costs, while a closer focus on the prevention of pneumonia may be advisable, eg, starting with citizens having COPD.

Abstract
OBJECTIVE To compare rates of hospitalization for serious infections, trends in rates from 1996 to 2011, and in-hospital mortality between patients with systemic lupus erythematosus (SLE) and those without SLE in a national sample. METHODS We analyzed hospitalizations for pneumonia, bacteremia/sepsis, urinary tract infections, skin infections, and opportunistic infections among adults in the Nationwide Inpatient Sample. We compared rates of hospitalization yearly among patients with SLE and the general population. We also computed odds ratios (ORs) for in-hospital mortality. RESULTS In 1996, the estimated number of hospitalizations for pneumonia in patients with SLE was 4,382, followed by sepsis (2,305), skin infections (1,422), urinary tract infections (643), and opportunistic infections (370). Rates were much higher in patients with SLE than in those without SLE, with age-adjusted relative risks ranging from 5.7 (95% confidence interval [95% CI] 5.5-6.0) for pneumonia to 9.8 (95% CI 9.1-10.7) for urinary tract infection in 1996. Risks increased over time, so that by 2011, all relative risks exceeded 12.0. Overall risk of in-hospital mortality was higher in SLE only for opportunistic infections (adjusted OR 1.52 [95% CI 1.12-2.07]). However, in pneumonia and sepsis, mortality risks were higher in SLE among those who required mechanical ventilation. CONCLUSION Hospitalization rates for serious infections in SLE increased substantially between 1996 and 2011, reaching over 12 times higher than in patients without SLE in 2011. Reasons for this acceleration are unclear. In-hospital mortality was higher among patients with SLE and opportunistic infections and those with pneumonia or sepsis who required mechanical ventilation.

Abstract
OBJECTIVE Little is known about risk factors and prognosis for postoperative pneumonia (POP) in patients undergoing therapeutic lung cancer (LC) surgery. METHODS We followed a nationwide population-based cohort of 7479 patients with LC surgery in Denmark 1995-2011. We used logistic regression analysis to examine risk factors for POP within 30 days after surgery. Subsequent survival in patients with POP was analyzed with Cox regression. RESULTS We identified 268 (3.6%) patients with POP. Important risk factors included advanced age (age ≥80 years: (adjusted odds ratio [aOR] = 3.64; 95% CI: 2.17-6.12) as compared to patients aged 50-59 years), previous pneumonia (aOR = 2.68; 95% CI: 2.02-3.56), obesity (aOR = 1.91; 95% CI: 0.99-3.69), chronic pulmonary disease (aOR = 1.90; 95% CI: 1.40-2.57), alcoholism (aOR = 1.56; 95% CI: 0.81-3.01), and atrial fibrillation (aOR = 1.42; 95% CI: 0.82-2.45). Overall thoracoscopic surgery halved the risk of POP and the highest risk of POP was seen in pneumonectomy performed in open thoracotomy. Among patients surviving the 30-day postoperative period, 31-365 day mortality was 21.6% in POP patients vs. 16.8% in non-POP patients, and 1-5-year mortality was 62.2% vs. 53.0%. Adjusted 31-365 day hazard ratio (HR) of death with POP was 1.31 (95% CI: 1.00-1.73), and 1-5 year HR was 1.22 (95% CI 0.98-1.53). CONCLUSION Major risk factors for POP following LC surgery are advanced age, previous pneumonia, obesity, chronic pulmonary disease, alcoholism, and atrial fibrillation. POP is a clinical marker for decreased LC survival.

Abstract
OBJECTIVE To examine if the introduction of pneumococcal conjugate vaccine (PCV) in Denmark was associated with a decrease in the rate of ventilation tube (VT) insertions performed by office-based practising ear, nose and throat (ENT) specialists. DESIGN Population-based register study based on prospectively collected data. SETTING Central Denmark Region. Data on VT insertions performed by any office-based practising ENT specialist in the region were collected from the National Health Service Registry. PARTICIPANTS All children below the age of 2 years with a first-time VT insertion from 2001 through 2011. MAIN OUTCOME MEASURES Age-stratified and gender-stratified standardised incidence rates of first-time VT insertion, and incidence rate ratio for PCV period 2008-2011 compared with pre-PCV period 2001-2007. RESULTS The annual incidence rate of first-time VT insertion in small children increased steadily from 64/1000 person-years in 2001 to 100/1000 person-years in 2011. The incidence rate ratio was 1.27 (95% CI 1.24 to 1.30) in the PCV period compared with the pre-PCV period. CONCLUSIONS The introduction of PCV into the Danish childhood immunisation programme in 2007 was not associated with a subsequent decrease in the rate of VT insertions among children below the age of 2 years. Instead, the rate continued to rise, as before the introduction of PCV. TRIAL REGISTRATION NUMBER Danish Data Protection Agency: 2007-58-0010.

Clinical burden of pneumonia, meningitis and septicemia in Norway 2 years after 7-valent pneumococcal conjugate vaccine introduction. Scand J Public Health 2015; 43:657-66.

Abstract
AIMS This population-based, retrospective study quantified the rates of all-cause and pneumococcal pneumonia, meningitis and septicemia in Norway from 2008 to 2009 and determined the proportions of cases caused by pneumococcal vaccine serotypes. METHODS Data on patients with all-cause and pneumococcal pneumonia, meningitis and septicemia were obtained from the Norwegian Patient Registry, which collects hospitalization data from all Norwegian public hospitals based on International Classification of Diseases codes. Norwegian Patient Registry case records linked to the Norwegian Surveillance System for Communicable Diseases provided serotype data for invasive pneumococcal disease in patients with microbiological cultures. RESULTS In 2008 and 2009, hospitalization rates were relatively stable for all-cause pneumonia (5.28 and 5.35, respectively, per 1000), meningitis (10.70 and 9.67, respectively, per 100,000), and septicemia (from 171.81 to 161.46 per 100,000). In contrast, rates decreased for International Classification of Diseases-10 diagnosed pneumococcal pneumonia (from 13.66 to 10.52 per 100,000), although these cases may be under-reported because of inclusion in all-cause pneumonia. Rates also decreased in diagnosed pneumococcal meningitis (from 1.60 to 1.19 per 100,000) and diagnosed pneumococcal septicemia (from 9.08 to 7.94 per 100,000). Diagnosed pneumococcal disease rates were highest in younger children and older adults, peaking at ⩾ 60 years old. Pneumococcal pneumonia, meningitis and septicemia caused by serotypes included in the 7-valent pneumococcal conjugate vaccine decreased substantially during the study period, with corresponding serotype replacement by non-7-valent pneumococcal conjugate vaccine serotypes. CONCLUSIONS From 2008 to 2009, International Classification of Diseases-10 diagnosed pneumococcal pneumonia, meningitis and septicemia decreased in most age groups but remained greatest among subjects aged 0-1 and ⩾ 60 years.

The Impact of Patient Profiles and Procedures on Hospitalization Costs through Length of Stay in Community-Acquired Pneumonia Patients Based on a Japanese Administrative Database. PLoS One 2015; 10:e0125284. [PMID: 25923785 PMCID: PMC4414582 DOI: 10.1371/journal.pone.0125284] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2015] [Accepted: 03/22/2015] [Indexed: 11/25/2022] Open
Abstract
Background Community-acquired pneumonia is a common cause of patient hospitalization, and its burden on health care systems is increasing in aging societies. In this study, we aimed to investigate the factors that affect hospitalization costs in community-acquired pneumonia patients while considering the intermediate influence of patient length of stay. Methods Using a multi-institutional administrative claims database, we analyzed 30,041 patients hospitalized for community-acquired pneumonia who had been discharged between April 1, 2012 and September 30, 2013 from 289 acute care hospitals in Japan. Possible factors associated with hospitalization costs were investigated using structural equation modeling with length of stay as an intermediate variable. We calculated the direct, indirect (through length of stay), and total effects of the candidate factors on hospitalization costs in the model. Lastly, we calculated the ratio of indirect effects to direct effects for each factor. Results The structural equation model showed that higher disease severities (using A-DROP, Barthel Index, and Charlson Comorbidity Index scores), use of mechanical ventilation, and tube feeding were associated with higher hospitalization costs, regardless of the intermediate influence of length of stay. The severity factors were also associated with longer length of stay durations. The ratio of indirect effects to direct effects on total hospitalization costs showed that the former was greater than the latter in the factors, except in the use of mechanical ventilation. Conclusions Our structural equation modeling analysis indicated that patient profiles and procedures impacted on hospitalization costs both directly and indirectly. Furthermore, the profiles were generally shown to have greater indirect effects (through length of stay) on hospitalization costs than direct effects. These findings may be useful in supporting the more appropriate distribution of health care resources.
