Reduced Step Count and Clinical Frailty in Hospitalized Adults With Community-Acquired Pneumonia.

BACKGROUND: In adults hospitalized with community-acquired pneumonia (CAP), increasing ward-based walking may reduce length of stay (LOS). There are few data to describe ward-based walking in this population. In adults hospitalized with CAP, we aimed to report variables of walking and non-walking time, to determine whether demographic or clinical variables influenced daily step count, and to determine whether daily step count influenced LOS. METHODS: Following admission, daily step count and variables related to walking and non-walking time were quantified using the StepWatch Activity Monitor. Details regarding demographics, clinical characteristics, clinical care, and LOS were extracted from the medical records and hospital electronic data systems. Frailty was calculated via the 7-point Clinical Frailty Scale; disease severity was measured via the CURB-65 score. Health care utilization at 30 d following discharge was measured via telephone interview. RESULTS: Two hundred participants completed the study, of whom 121 contributed ≥ 24 h of data from the StepWatch Activity Monitor. The median (interquartile range (IQR)) number of daily steps was 926 (457-1706). These were accumulated over 66 (41-121) min/d, with a usual bout duration of 3 (2-4) min and 1-min peak cadence of 56 (43-74) steps/min. An average of 93% (89-96) of waking hours was spent in non-walking time. In the multivariable model, increased frailty was retained as a predictor of lower step count (incidence rate ratio [IRR] 0.59, 95% CI 0.41-0.85). For every increase in 500 steps/d, LOS reduced by 11% (IRR 0.89, 95% CI 0.80-0.99). CONCLUSIONS: Subjects hospitalized with CAP did very little walking, most of which was accumulated in short bouts at a low intensity. Compared with subjects with mild frailty, those with moderate to severe frailty took 59% fewer steps per day. Those with a higher daily step count had a shorter LOS.

Early readmission and mortality in acute exacerbation of chronic obstructive pulmonary disease with community-acquired pneumonia.

Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are important causes of hospital admission and mortality. Pneumonia is a major contributor to hospitalization for AECOPD and has a close relationship with poor outcomes. We performed a prospective cohort study to evaluate the prognosis of AECOPD patients with or without community-acquired pneumonia (CAP) who hospitalized from January 2012 to December 2015. We investigated mortality and readmission rates within 6 months after the first admission between two groups and analyzed the difference of survival rate according to readmission duration (≤30 vs. >30 days) or intensive care unit (ICU) treatment. Total 308 AECOPD patients (134 with CAP and 174 without CAP) were enrolled. The mean age was 72.3 ± 9.5 years old, and 235 patients (76.3%) were male. The 180-day mortality was higher in AECOPD with CAP than without CAP (24.6% vs. 13.2%; hazard ratio (HR): 1.982; 95% CI: 1.164-3.375; p = 0.012). However, readmission rate showed no significant difference between two groups (51.5% vs. 46.6%; HR: 1.172; 95% CI: 0.850-1.616; p = 0.333). It showed a significantly lower survival rate in AECOPD with CAP rather than without CAP when were readmitted within 30 days (HR: 1.738; 95% CI:1.063-3.017; p = 0.031). According to ICU treatment, survival rate was not significantly different between two groups. Multivariate analysis revealed the readmission within 30 days ( p < 0.001), serum hemoglobin concentration ( p = 0.010), and albumin level ( p = 0.049) were significantly associated with 180-day mortality of AECOPD with CAP. AECOPD with CAP showed lower survival rate than AECOPD without CAP during 6 months. Early readmission within 30 days was significantly associated with an increased risk of mortality.

After-hours respiratory physiotherapy for intubated and mechanically ventilated patients with community-acquired pneumonia: An Australian perspective.

INTRODUCTION: Community acquired pneumonia (CAP) is a common reason for admission to an intensive care unit for intubation and mechanical ventilation, and results in high morbidity and mortality. The primary aim of the study was to investigate availability and provision of respiratory physiotherapy, outside of normal business hours, for intubated and mechanically ventilated adults with CAP in Australian hospitals. MATERIALS AND METHODS: A cross-sectional, mixed methods online survey was conducted. Participants were senior intensive care unit physiotherapists from 88 public and private hospitals. Main outcome measures included presence and nature of an after-hours physiotherapy service and factors perceived to influence the need for after-hours respiratory physiotherapy intervention, when the service was available, for intubated adult patients with CAP. Data were also collected regarding respiratory intervention provided after-hours by other ICU professionals. RESULTS: Response rate was 72% (n=75). An after-hours physiotherapy service was provided by n=31 (46%) hospitals and onsite after-hours physiotherapy presence was limited (22%), with a combination of onsite and on-call service reported by 19%. Treatment response (83%) was the most frequent factor for referring patients with CAP for after-hours physiotherapy intervention by the treating day-time physiotherapist. Nurses performing respiratory intervention (77%) was significantly associated with no available after-hours physiotherapy service (p=0.04). DISCUSSION: Physiotherapy after-hours service in Australia is limited, therefore it is common for intubated patients with CAP not to receive any respiratory physiotherapy intervention outside of normal business hours. In the absence of an after-hours physiotherapist, nurses were most likely to perform after-hours respiratory intervention to intubated patients with CAP. CONCLUSION: Further research is required to determine whether the frequency of respiratory physiotherapy intervention, including after-hours provision of treatment, influences outcomes for ICU patients intubated with pneumonia.

[Physical therapy intervention during hospitalization in patients with acute exacerbation of chronic obstructive pulmonary disease and pneumonia: A randomized clinical trial]. / Intervención fisioterápica durante la hospitalización en pacientes con exacerbación aguda de la enfermedad pulmonar obstructiva crónica y neumonía: un ensayo clínico aleatorizado.

BACKGROUND AND OBJECTIVE: Respiratory infections involve not only hospitalization due to pneumonia, but also acute exacerbations of COPD (AECOPD). The objective of the present study was to evaluate the effectiveness of a physical therapy intervention during hospitalization in patients admitted due to community-acquired pneumonia (CAP) and AECOPD. MATERIAL AND METHOD: Randomized clinical trial, 44 patients were randomized into 2 groups: a control group which received standard medical therapy (oxygen therapy and pharmacotherapy) and an experimental group that received standard treatment and a physical therapy intervention (breathing exercises, electrostimulation, exercises with elastic bands and relaxation). RESULTS: Between-groups analysis showed that after the intervention (experimental vs. control) significant differences were found in perceived dyspnoea (P=.041), and right and left quadriceps muscle strength (P=.008 and P=.010, respectively). In addition, the subscale of "domestic activities" of the functional ability related to respiratory symptoms questionnaire showed significant differences (P=.036). CONCLUSION: A physical therapy intervention during hospitalization in patients with AECOPD and CAP can generate skeletal muscle level gains that exceed the deterioration caused by immobilization during hospitalization.

Importance of functional assessment in the management of community-acquired and healthcare-associated pneumonia.

OBJECTIVE: In Japan, the number of elderly people who have difficulties performing the activities of daily living (ADLs) is increasing. The objective of this study was to assess the relationship between ADL and the clinical characteristics of pneumonia. METHODS: We conducted a retrospective study of 219 adult patients hospitalized due to pneumonia [151 patients with community-acquired pneumonia (CAP) and 68 patients with healthcare-associated pneumonia (HCAP)]. CAP, HCAP, and all the patients were stratified into two groups using a modified version of the Katz index of five ADLs as follows: independent in all ADLs or dependent in one to three ADLs (CAP-A, HCAP-A, and All-A groups) and dependent in four or five ADLs (CAP-B, HCAP-B, and All-B groups). Disease severity, microbiological findings, and mortality were compared between the groups. RESULTS: As the ability to perform ADLs declined, A-DROP scores (the CAP severity measurement index) increased significantly in CAP (CAP-A: 1.1±1.1, CAP-B: 2.6±1.1), HCAP (HCAP-A: 2.0±1.0, HCAP-B: 2.8±1.0), and all patients (All-A: 1.3±1.1, All-B: 2.8±1.0). Thirty-day mortality was higher in the CAP-B (23.1%) and All-B (19.2%) groups than in the CAP-A (0.7%) and All-A (1.8%) groups, respectively. A multivariate Cox proportional hazards analysis showed an ADL score ≥ four to be a significant predictor of 30-day mortality in CAP patients [hazard ratio (HR), 19.057; 95% confidence interval (CI), 1.930-188.130] and in all patients (HR, 8.180; 95% CI, 1.998-33.494). CONCLUSION: A functional assessment using a modified version of the Katz index is useful for the management of CAP and HCAP patients.

Elderly patients with community-acquired pneumonia are not treated according to current guidelines.

INTRODUCTION: Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality in elderly patients, and the most important cause of death in the developed world. Optimised treatment and care will benefit patients as well as the health economy. This study investigated in-hospital compliance with guidelines for treatment and care of patients with CAP. MATERIAL AND METHODS: A retrospective nationwide study examining 100 patient records from 20 Danish hospitals regarding patients 65 years and older admitted for CAP. RESULTS: A total of 74 patients with a mean age 81.6 years were included. The mean length of stay was 9.2 days, 30- and 90-day mortality rates were 12.2 and 17.6% and readmission rates 4% (seven days) and 9.5% (30 days). Severity assessment was made in two cases. Observations of vital parameters were unsystematic and the respiratory rate was measured only in six cases. Diagnostic tests and treatment initiation were mostly in accordance with guidelines. The mean number of days on intravenous antibiotics was 5.5. Nutrition and mobilisation were neglected or only sporadically addressed. No systematic plan for treatment and care was found. CONCLUSION: While medical treatment mainly concurred with guidelines, a potential for reduced costs by early discharge planning and use of systematic assessment tools for site-of-care and treatment decisions was indicated. The lack of systematic interventions in the prevention and treatment of malnutrition and functional decline constitutes a threat to a successful final patient outcome. FUNDING: The Danish Ministry of Health funded the study. TRIAL REGISTRATION: The Danish Data Register approved the project (J. No. 2010-41-5358).

National hospitalization trends for pediatric pneumonia and associated complications.

OBJECTIVE: To determine current rates of and trends in hospitalizations for community-acquired pneumonia (CAP) and CAP-associated complications among children. METHODS: We performed a cross-sectional, retrospective, cohort study by using the 1997, 2000, 2003, and 2006 Kids' Inpatient Database. National estimates for CAP and CAP-associated local and systemic complication rates were calculated for children < or =18 years of age. Patients with comorbid conditions or in-hospital birth status were excluded. Percentage changes were calculated by using 1997 (before heptavalent pneumococcal conjugate vaccine [PCV7]) and 2006 (after PCV7) data. RESULTS: There were a total of 619,102 CAP discharges for 1997, 2000, 2003, and 2006, after application of inclusion and exclusion criteria. Overall rates of CAP discharges did not change substantially between 1997 and 2006, but stratification according to age revealed a 22% decrease for children <1 year of age, minimal change for children 1 to 5 years of age, and increases for children 6 to 12 years (22%) and > or =13 years (41%) of age. Systemic complication rates were highest among children <1 year of age but decreased by 36%. In all other age groups, systemic complication rates remained stable. Local complication rates increased 78% overall. Children 1 to 5 years of age had the highest local complication rates. CONCLUSIONS: After the introduction of PCV7 in 2000, rates of CAP-associated systemic complications decreased only for children <1 year of age. Rates of pediatric CAP-associated local complications are increasing in all age groups.

Pneumonia recovery: discrepancies in perspectives of the radiologist, physician and patient.

BACKGROUND: Chest radiographs are often used to diagnose community-acquired pneumonia (CAP), to monitor response to treatment and to ensure complete resolution of pneumonia. However, radiological exams may not reflect the actual clinical condition of the patient. OBJECTIVE: To compare the radiographic resolution of mild to moderately severe CAP to resolution of clinical symptoms as assessed by the physician or rated by the patient. DESIGN: Prospective cohort study. PARTICIPANTS: One hundred nineteen patients admitted because of mild to moderately severe CAP with new pulmonary opacities. MAIN MEASURES: Radiographic resolution and clinical cure of CAP were determined at day 10 and 28. Radiographic resolution was defined as the absence of infection-related abnormalities; clinical cure was rated by the physician and defined by improvement of signs and symptoms. In addition, the CAP score, a patient-based symptom score, was calculated. KEY RESULTS: Radiographic resolution, clinical cure and normalization of the CAP score were observed in 30.8%, 93% and 32% of patients at day 10, and in 68.4%, 88.9% and 41.7% at day 28, respectively. More severe CAP (PSI score >90) was independently associated with delayed radiographic resolution at day 28 (OR 4.7, 95% CI 1.3-16.9). All 12 patients with deterioration of radiographic findings during follow-up had clinical evidence of treatment failure. CONCLUSIONS: In mild to moderately severe CAP, resolution of radiographic abnormalities and resolution of symptoms scored by the patient lag behind clinical cure assessed by physicians. Monitoring a favorable disease process by routine follow-up chest radiographs seems to have no additional value above following a patient's clinical course.

[Complete bed rest prescription in an internal medicine ward: a dangerous treatment?]. / Prescrire "le lit strict" dans un service hospitalier de médecine interne: un traitement dangereux?

A general knowledge led to the assumption that bed rest is beneficial for most illnesses and bed rest is prescribed in a large number of medical conditions. However, evidence from randomised studies and systematic reviews suggest a potentially harmful effect of bed rest. This review article discusses the utility of bed rest in some frequent medical pathologies such as myocardial infarction, pulmonary embolism, community acquired-pneumonia, and low back pain.

Managing postacute hospital care: a case for biopsychosocial needs.

OBJECTIVE: This study aimed to investigate whether, for an identical diagnosis, patients who were transferred to a postacute care (PAC) facility had a higher biopsychosocial complexity than patients who were discharged home. METHODS: This prospective study employed group comparison that included 166 patients who were consecutively admitted to an acute care internal medicine ward for acute congestive heart failure, pneumonia or exacerbation of chronic obstructive pulmonary disease, and malaise or fall. Patients were evaluated within their first 48 h of stay. Biomedical, functional, quality of life, and case complexity data were collected. Factors associated with a transfer to the PAC facility were identified through logistic regression modeling. RESULTS: Fifty-eight patients (34.9%) were transferred. In the multivariate analyses, case complexity score [per point: odds ratio (OR)=1.29; 95% CI=1.18-1.41] and nursing workload (OR=1.06; 95% CI=1.01-1.12) were associated with the transfer. At a cutoff point of > or =33, the case complexity score predicted transfer to the PAC facility with a sensitivity of 79% and a specificity of 84% (positive predictive value=73.0%; negative predictive value=88.4%) and correctly classified 83% of the cases. CONCLUSIONS: Biomedical characteristics alone did not differentiate patients who were transferred versus those who were discharged home, nor did it predict PAC use. This was also true for specific severity scores of cardiac failure and pneumonia as well as for the comorbidity index. Psychosocial parameters were significantly associated to this process as well as a higher nursing workload.

[Community-acquired pneumonia among the elderly: differences between patients living at home and in nursing homes]. / La neumonía adquirida en la comunidad de los ancianos: diferencias entre los que viven en residencias y en domicilios particulares.

OBJECTIVE: The etiology, presentation, and prognosis of community-acquired pneumonia (CAP) among nursing home residents are believed to differ from those of other groups. However, few Spanish studies have confirmed those assumptions or studied regional differences in CAP etiology. PATIENTS AND METHODS: A prospective study which included all patients over 65 years of age admitted to our hospital with CAP was carried out over a period of 18 months (2002-2003). We examined clinical, analytical, and radiographic characteristics paying particular attention to functional status--using the Eastern Cooperative Oncology Group (ECOG) scale and Barthel and Karnofsky indices--and comorbidity. Two blood cultures, a Legionella antigen test in urine, and serology for atypical bacteria were used for the etiologic diagnosis; bacterial cultures of respiratory samples were also used in certain cases. RESULTS: Ninety-one patients, 25 of whom were nursing home residents, were enrolled. The nursing home residents were older than the other patients (mean [SD] age of 82 [4] compared with 73 [5]; P=.0001) and had greater comorbidity (P=.0001)--with a significantly greater presence of diabetes mellitus, cerebrovascular disease, congestive heart failure, and dementia. They also had a poorer functional status (ECOG, 2.09 [0.9] compared with 0.93 [1.1], P=.001; Barthel Index, 19 [33] compared with 77 [35], P=.001; Karnofsky In-dex, 51 [17] compared with 78 [23], P=.001). Regarding clinical characteristics, significant differences were found for respiratory rate (39 [11] compared with 27 [7] breaths/min; P=.001), blood pressure (69.5 [20] compared with 79.2 [18] mm Hg; P=.029), and temperature (36.6 [1.2] compared with 37.7 [1.1] degrees C; P=.001). CAP patients from nursing homes presented a greater number of affected lobules in chest x-rays (P=.004), more hypoxemia, acidosis, anemia, hypoalbuminemia, and greater scores of urea and creatinine. Fine Scale scores were also greater (134 [26] compared with 95 [28]; P=.001) as was mortality (7/25 compared with 3/66; P=.005). Few patients had an etiologic diagnosis and no significant differences were observed between the groups. The variable that predicted mortality in elderly patients in this series, according to stepwise logistic regression, was urea (adjusted R2=0.452). CONCLUSIONS: In our sample population, nursing home residents were older, had greater comorbidity, and severe functional impairment. Under these circumstances the severity of CAP increases and becomes an important cause of mortality despite the fact that the etiologic agents do not appear to differ from those of the other patients.

Early mobilization of patients hospitalized with community-acquired pneumonia.

STUDY OBJECTIVE: To determine if early mobilization (EM) of hospitalized adults with community-acquired pneumonia (CAP) reduces hospital length of stay. DESIGN: Group randomized trial. SETTING: Three Midwestern hospitals. PARTICIPANTS: Four hundred fifty-eight patients with CAP admitted to 17 general medical units between November 1997 and April 1998. INTERVENTION: EM was defined as sitting out of bed or ambulating for at least 20 min during the first 24 h of hospitalization. Progressive mobilization occurred each subsequent day during hospitalization. MEASUREMENTS AND RESULTS: Intervention (n = 227) and usual-care patients (n = 231) were similar in age, gender, disease severity, door-to-drug delivery time, and IV-to-po switchover time. Hospital length of stay for EM vs usual care was significantly less (mean, 5.8 vs 6.9 days; adjusted absolute difference, 1.1 days; 95% confidence interval, 0.0 to 2.2 days). There were no differences in adverse events or other secondary outcomes between treatment groups. CONCLUSIONS: Like patients hospitalized with acute myocardial infarction and total knee replacements, EM of hospitalized patients with CAP reduces overall hospital length of stay and institutional resources without increasing the risk of adverse outcomes.

[Prognostic factors associated with community-acquired aspiration pneumonia]. / Factores pronósticos de la neumonía por aspiración adquirida en la comunidad.

BACKGROUND: Aspiration pneumonia (AP) represents about 5-24% of community-acquired pneumonias. This condition mainly affects elderly patients and causes a high mortality. Our objective was to quantify the AP mortality rate and to identify prognostic factors upon patients admission. PATIENTS AND METHOD: We underwent a retrospective observational study of a cohort of AP patients admitted to a tertiary care hospital during a 29 months period. The in-hospital mortality rate was calculated. To identify prognostic factors, basal characteristics of patients as well as their clinical presentation and complementary tests performed on admission were studied and analyzed by univariate and multivariate techniques. Odds ratios and 95% confidence intervals were estimated. RESULTS: Thirty six out of 105 admitted patients with AP died (cumulative mortality incidence rate 34%, 95% CI 25-44%). In the univariate analysis, demographic, clinical and complementary test variables were associated with mortality. Final logistic model revealed the following independent variables: living in a nursing home (OR = 3.4; 95% CI 1.1-10.9), high degree of dependence (OR = 0.3; 95% CI, 0.1-0.9), body temperature (OR = 0.5 per Celsius degree; 95% CI, 0.3-1.0), serum creatinine levels (OR = 2.2 per mg/100 ml; 95% CI, 1.2-4.1) and LDH serum concentrations (OR = 1.5 per 100 IU/L; 95% CI, 1.1-2.0). CONCLUSIONS: The mortality of community-acquired AP is very high. In addition to clinical and biological parameters on admission such as body temperature and LDH and creatinine serum concentrations, living in a nursing home and having a high degree of dependence for the basic daily activities were identified as independent prognostic factors. An in-depth knowledge of prognostic factors related to pre-admission care and assistance is needed to decrease the mortality in these patients.

Bottle-blowing in hospital-treated patients with community-acquired pneumonia.

A study was carried out to determine whether bottle-blowing has any positive effects in patients with pneumonia. In a prospective open study 145 adults with untreated community-acquired pneumonia requiring hospitalization were randomized to early mobilization (group A), to sit up and take 20 deep breaths on 10 occasions daily (group B), or to sit up and to blow bubbles in a bottle containing 10 cm water through a plastic tube 20 times on 10 occasions daily (group C). Peak expiratory flow (PEF), vital capacity (VC), forced expiratory volume in 1 sec (FEV1) and serum concentration of C-reactive protein (CRP) were determined on admission, and on days 4 and 42. Fever duration and hospital stay were recorded. In a subset of 16 patients, single breath diffusion capacity of carbon monoxide was measured on 3 occasions. The patients in group A were hospitalized for a mean of 5.3 days, group B for 4.6 days and group C for 3.9 days. Treatment was a significant factor (p = 0.037) in a Cox regression model, with group C significantly better than group A (p = 0.01). The number of days with fever was 2.3, 1.7 and 1.6 in groups A, B and C respectively. These differences were not significant (p = 0.28). No significant differences were found between the groups regarding CRP, PEF, VC, FEV1, or diffusion capacity. Intensive bottle-blowing shortens the hospital stay in patients with pneumonia. The underlying mechanism is not clear.
