High rate of viral identification and coinfections in infants with acute bronchiolitis

OBJECTIVES

To determine the viruses and risk factors associated with hospital and intensive care unit (ICU) admissions in infants with acute bronchiolitis.

INTRODUCTION

Bronchiolitis is a major cause of morbidity in infants. Widespread use of molecular-based methods has yielded new insights about its etiology, but the impact of viral etiologies on early outcomes is still unclear.

METHODS

Seventy-seven infants with bronchiolitis who were under two years of age and visited an emergency unit were included. Using molecular-based methods, samples were tested for 12 different respiratory viruses. Logistic regression models were used to identify clinical and virological variables associated with the main endpoints: hospital admission and ICU admission.

RESULTS

We identified at least one virus in 93.5% of patients, and coinfections were found in nearly 40% of patients. RSV was the most common pathogen (63.6%), followed by rhinovirus (39%). Identification of RSV was only associated with an increased risk of hospital admission in the univariate model. Younger age and enterovirus infection were associated with an increased risk of hospital admission, while atopy of a first-degree relative showed a protective effect. Prematurity was associated with an increased risk of admission to the ICU. Coinfections were not associated with worse outcomes.

CONCLUSIONS

Molecular-based methods resulted in high rates of viral identification but did not change the significant role of RSV in acute bronchiolitis. Younger age and enterovirus infection were risk factors for hospital admission, while prematurity appeared to be a significant risk factor for admission to the ICU in acute viral bronchiolitis.

Asthma morbidity among children evaluated by asthma case detection

OBJECTIVE

Population-based asthma detection is a potential strategy to reduce asthma morbidity in children; however, the burden of respiratory symptoms and health care use among children identified by case detection is not well known.

METHODS

Data come from a school-based asthma case detection validation study of 3539 children. Respiratory symptoms, emergency department (ED) visits, and hospitalizations were assessed by questionnaire for children whose case detection result and physician study diagnosis agreed.

RESULTS

Physician evaluation of 530 case detection results yielded 420 cases of agreement (168 children with previously diagnosed asthma, 39 with undiagnosed asthma, and 213 without asthma). Children with previously diagnosed asthma were more likely to be male (P < .0001). No differences in severity were observed in children with previously and undiagnosed asthma (P = .31). Children with undiagnosed asthma reported less frequent daytime and nighttime symptoms than children with previously diagnosed asthma but more than those without asthma (P < .0001). The proportion of children with at least 1 respiratory-related ED visit in the past year was 32%, 3%, and 3% for those with previously diagnosed, undiagnosed, and no asthma, respectively (P < .0001). The proportion with at least 1 respiratory-related hospitalization was 8%, 0%, and 0%, respectively (P < .0001). There were no differences in nonrespiratory ED visits (P = .93).

CONCLUSIONS

Despite similar physician-rated severity, children with undiagnosed asthma reported significantly less frequent respiratory symptoms and health care use than children with previously diagnosed asthma. These findings suggest that the potential health gains from case detection may be smaller than expected.

Hospitalizations after heart failure diagnosis a community perspective

OBJECTIVES

The purpose of this study was to determine the lifetime burden and risk factors for hospitalization after heart failure (HF) diagnosis in the community.

BACKGROUND

Hospitalizations in patients with HF represent a major public health problem; however, the cumulative burden of hospitalizations after HF diagnosis is unknown, and no consistent risk factors for hospitalization have been identified.

METHODS

We validated a random sample of all incident HF cases in Olmsted County, Minnesota, from 1987 to 2006 and evaluated all hospitalizations after HF diagnosis through 2007. International Classification of Diseases-9th Revision codes were used to determine the primary reason for hospitalization. To account for repeated events, Andersen-Gill models were used to determine the predictors of hospitalization after HF diagnosis. Patients were censored at death or last follow-up.

RESULTS

Among 1,077 HF patients (mean age 76.8 years, 582 [54.0%] female), 4,359 hospitalizations occurred over a mean follow-up of 4.7 years. Hospitalizations were common after HF diagnosis, with 895 (83.1%) patients hospitalized at least once, and 721 (66.9%), 577 (53.6%), and 459 (42.6%) hospitalized > or =2, > or =3, and > or =4 times, respectively. The reason for hospitalization was HF in 713 (16.5%) hospitalizations and other cardiovascular in 936 (21.6%), whereas over one-half (n = 2,679, 61.9%) were noncardiovascular. Male sex, diabetes mellitus, chronic obstructive pulmonary disease, anemia, and creatinine clearance <30 ml/min were independent predictors of hospitalization (p < 0.05 for each).

CONCLUSIONS

Multiple hospitalizations are common after HF diagnosis, though less than one-half are due to cardiovascular causes. Comorbid conditions are strongly associated with hospitalizations, and this information could be used to define effective interventions to prevent hospitalizations in HF patients.

Risk of hospitalizations after spinal cord injury: relationship with biographical, injury, educational, and behavioral factors

STUDY DESIGN

Cross-sectional survey.

OBJECTIVES

To assess the risk factors associated with hospitalization and the relationship of individual health behaviors with hospitalizations after spinal cord injury (SCI).

SETTING

A large specialty hospital in the southeastern USA.

METHODS

Persons with SCI responded (n=1386) to a mail survey assessing various aspects of their health, including health behaviors and number of hospitalizations in the past year. Logistic regression was used to assess the relationships between biographical, injury, educational, and health behavior factors with hospitalization in the past year.

RESULTS

Overall, 36.6% of participants were hospitalized on at least one occasion during the earlier year. Two biographical and injury characteristics were associated with hospitalization: race and SCI severity. Specifically, minorities and persons with non-ambulatory high cervical or non-cervical SCI were more likely to be hospitalized. Three behavioral factors were significantly associated with hospitalization after controlling for biographical and injury characteristics. Persons who used prescription medications, those who engaged more in smoking behaviors, and persons who reported more SCI-specific health behaviors were more likely to be hospitalized.

CONCLUSION

Specific health behaviors are associated with an increased hospitalization among persons with SCI. Future research is needed to assess the time sequence of these relationships.

Mortality after hospitalization with mild, moderate, and severe hyponatremia

BACKGROUND

Hyponatremia is the most common electrolyte abnormality in hospitalized individuals.

METHODS

To investigate the association between serum sodium concentration and mortality, we conducted a prospective cohort study of 98,411 adults hospitalized between 2000 and 2003 at 2 teaching hospitals in Boston, Massachusetts. The main outcome measures were in-hospital, 1-year, and 5-year mortality. Multivariable logistic regression and Cox proportional hazards models were used to compare outcomes in patients with varying degrees of hyponatremia against those with normal serum sodium concentration.

RESULTS

Hyponatremia (serum sodium concentration <135 mEq/L) was observed in 14.5% of patients on initial measurement. Compared with patients with normonatremia (135-144 mEq/L), those with hyponatremia were older (67.0 vs 63.1 years, P <.001) and had more comorbid conditions (mean Deyo-Charlson Index 1.9 vs 1.4, P <.001). In multivariable-adjusted models, patients with hyponatremia had an increased risk of death in hospital (odds ratio 1.47, 95% confidence interval [CI], 1.33-1.62), at 1 year (hazard ratio 1.38, 95% CI, 1.32-1.46), and at 5 years (hazard ratio 1.25, 95% CI, 1.21-1.30). The increased risk of death was evident even in those with mild hyponatremia (130-134 mEq/L; odds ratio 1.37, 95% CI, 1.23-1.52). The relationship between hyponatremia and mortality was pronounced in patients admitted with cardiovascular disease, metastatic cancer, and those admitted for procedures related to the musculoskeletal system. Resolution of hyponatremia during hospitalization attenuated the increased mortality risk conferred by hyponatremia.

CONCLUSION

Hyponatremia, even when mild, is associated with increased mortality.

Institutional blood glucose monitoring system for hospitalized patients: an integral component of the inpatient glucose control program

BACKGROUND

The ability to measure patient blood glucose levels at bedside in hospitalized patients and to transmit those values to a central database enables and facilitates glucose control and follow-up and is an integral component in the care of the hospitalized diabetic patient.

OBJECTIVE

The goal of this study was to evaluate the performance of an institutional glucometer employed in the framework of the Program for the Treatment of the Hospitalized Diabetic Patient (PTHDP) at E. Wolfson Medical Center, Holon, Israel.

METHODS

As part of the program to facilitate glucose control in hospitalized diabetic patients, an institutional glucometer was employed that permits uploading of data from stands located in each inpatient department and downloading of that data to a central hospital-wide database. Blood glucose values from hospitalized diabetic patients were collected from August 2007 to October 2008. The inpatient glucose control program was introduced gradually beginning January 2008.

RESULTS

During the follow-up period, more than 150,000 blood glucose measures were taken. Mean glucose was 195.7 +/- 99.12 mg/dl during the follow-up period. Blood glucose values declined from 206 +/- 105 prior to PTHDP (August 2007-December 2007) to 186 +/- 92 after its inception (January 2008-October 2008). The decline was associated significantly with time (r = 0.11, p < 0.0001). The prevalence of blood glucose values lower than 60 mg/dl was 1.48% [95% confidence interval (CI) 0.36%] prior to vs 1.55% (95% CI 0.37%) following implementation of the PTHDP. Concomitantly, a significant increase in the proportion of blood glucose values between 80 and 200 mg/dl was observed, from 55.5% prior to program initiation vs 61.6% after program initiation (p < 0.0001).

CONCLUSIONS

The present study was designed to observe changes in institution-wide glucose values following implementation of the PTHDP. Information was extracted from the glucometer system itself. Because the aforementioned study was not a clinical trial, we cannot rule out that factors other than introduction of the program could explain some of the variability observed. With these limitations in mind, it nevertheless appears that the PTHDP, of which the institutional glucometer is an integral, essential component, was associated with improved blood glucose values in the hospitalized diabetic patient.

Hospitalization subsequent to diagnosis in young patients with diabetes in Chicago, Illinois

OBJECTIVES

Rehospitalization after a diabetes diagnosis in youth signals the failure of outpatient management. We examined risk factors for rehospitalization among young patients with diabetes.

PATIENTS AND METHODS

We queried 535 participants diagnosed before 18 years of age from the Chicago Childhood Diabetes Registry. Demographic, social, and clinical data were used in logistic models of diabetes-related rehospitalization, as well as, among those rehospitalized, frequent (> or = once per 2 years' duration) versus infrequent rehospitalization rates.

RESULTS

Mean (range) duration was 5.1 years (0.1-19.2 years). The sample was 55% non-Hispanic black, 11% non-Hispanic white, 26% Hispanic, and 7% other/mixed race; 86% had presumed type 1 diabetes; and 47% were underinsured. Overall, 46% reported rehospitalization for diabetes. In multivariable logistic regression, ever being rehospitalized was significantly associated with diabetes duration (per year, odds ratio [OR]: 1.26; P < .01), female gender (OR: 1.67; P = .01), underinsurance (versus private insurance; OR: 1.79; P < .01), presumed phenotype (non-type 1 diabetes versus type 1; OR: 0.32; P < .01), and diagnosis at a community hospital (versus tertiary care facility; OR: 1.96; P < .01) and tended to be higher for those of nonwhite race (OR: 1.94; P = .07). Among those rehospitalized, multivariable associations with frequent rehospitalization were presumed phenotype (non-type 1 diabetes versus type 1; OR: 2.74; P = .04), head of household not working (versus employed; OR: 1.88; P = .02), and younger age at questionnaire (per year; OR: 0.94; P = .01).

CONCLUSIONS

Rehospitalization is common in young patients with diabetes, especially for those with limited resources, indicating the need for improved outpatient services. Comprehensive initial education and support available to young patients with diabetes diagnosed at tertiary care facilities and their families may have lasting protective effects.

Predictors of clinical outcomes and hospital resource use of children after tracheotomy

OBJECTIVES

The objectives are to describe health outcomes and hospital resource use of children after tracheotomy and identify patient characteristics that correlate with outcomes and hospital resource use.

PATIENTS AND METHODS

A retrospective analysis of 917 children aged 0 to 18 years undergoing tracheotomy from 36 children's hospitals in 2002 with follow-up through 2007. Children were identified from ICD-9-CM tracheotomy procedure codes. Comorbid conditions (neurologic impairment [NI], chronic lung disease, upper airway anomaly, prematurity, and trauma) were identified with ICD-9-CM diagnostic codes. Patient characteristics were compared with in-hospital mortality, decannulation, and hospital resource use by using generalized estimating equations.

RESULTS

Forty-eight percent of children were <or=6 months old at tracheotomy placement. Chronic lung disease (56%), NI (48%), and upper airway anomaly (47%) were the most common underlying comorbid conditions. During hospitalization for tracheotomy placement, children with an upper airway anomaly experienced less mortality (3.3% vs 11.7%; P < .001) than children without an upper airway anomaly. Five years after tracheotomy, children with NI experienced greater mortality (8.8% vs 3.5%; P <or= .01), less decannulation (5.0% vs 11.0%; P <or= .01), and more total number of days in the hospital (mean [SE]: 39.5 [4.0] vs 25.6 [2.6] days; P <or= .01) than children without NI. These findings remained significant (P < .01) in multivariate analysis after controlling for other significant cofactors.

CONCLUSIONS

Children with upper airway anomaly experienced less mortality, and children with NI experienced higher mortality rates and greater hospital resource use after tracheotomy. Additional research is needed to explore additional factors that may influence health outcomes in children with tracheotomy.

Heart failure: the commonest reason for hospital admission in Germany: medical and economic perspectives

BACKGROUND

Heart failure is now the commonest reason for hospitalization in Germany (German Federal Statistical Office, 2008). Heart failure will continue to be a central public health issue in the future as the population ages. This article focuses on regional differences, the costs of the disease, and the expected rate of increase in cases in the near future.

METHODS

This analysis is based on diagnosis statistics, cause-of-death statistics, and cost of illness data, as reported by the German Federal Statistical Office. Age- and sex-specific differences are taken into account.

RESULTS

2006 was the first year in which heart failure led to more hospital admissions in Germany (317 000) than any other diagnosis. At present, about 141 000 persons in Germany aged 80 and over have heart failure; by the year 2050, it is predicted that more than 350 000 persons in this age group will be affected. The rate of diagnosis of heart failure, its frequency as a cause of death, and the costs associated with it all vary across the individual states of the Federal Republic of Germany. The nationwide cost of heart failure in 2006 was estimated at 2.9 billion euros.

CONCLUSIONS

These findings reveal that heart failure has become more common as an admission diagnosis of hospitalized patients in Germany. Because the population is aging, new concepts for prevention and treatment will be needed in the near future so that the affected patients can continue to receive adequate care.

Osteoporotic fractures and hospitalization risk in chronic spinal cord injury

Osteoporosis is a well acknowledged complication of spinal cord injury. We report that motor complete spinal cord injury and post-injury alcohol consumption are risk factors for hospitalization for fracture treatment. The clinical assessment did not include osteoporosis diagnosis and treatment considerations, indicating a need for improved clinical protocols.

INTRODUCTION

Treatment of osteoporotic long bone fractures often results in lengthy hospitalizations for individuals with spinal cord injury. Clinical features and factors that contribute to hospitalization risk have not previously been described.

METHODS

Three hundred and fifteen veterans > or = 1 year after spinal cord injury completed a health questionnaire and underwent clinical exam at study entry. Multivariate Cox regression accounting for repeated events was used to assess longitudinal predictors of fracture-related hospitalizations in Veterans Affairs Medical Centers 1996-2003.

RESULTS

One thousand four hundred and eighty-seven hospital admissions occurred among 315 participants, and 39 hospitalizations (2.6%) were for fracture treatment. Median length of stay was 35 days. Fracture-related complications occurred in 53%. Independent risk factors for admission were motor complete versus motor incomplete spinal cord injury (hazard ratio = 3.73, 95% CI = 1.46-10.50). There was a significant linear trend in risk with greater alcohol consumption after injury. Record review indicated that evaluation for osteoporosis was not obtained during these admissions.

CONCLUSIONS

Assessed prospectively, hospitalization in Veterans Affairs Medical Centers for low-impact fractures is more common in motor complete spinal cord injury and is associated with greater alcohol use after injury. Osteoporosis diagnosis and treatment considerations were not part of a clinical assessment, indicating the need for improved protocols that might prevent low-impact fractures and related admissions.

Trends in high-turnover stays among children hospitalized in the United States, 1993-2003

OBJECTIVE

Brief hospitalizations for children may constitute an opportunity to provide care in an alternative setting such as an observation unit. The goal of this study was to characterize recent national trends in brief inpatient stays for children in the United States.

METHODS

Using the Nationwide Inpatient Sample from 1993-2003, we analyzed hospital discharges among children <18 years of age, excluding births, deaths, and transfers. Hospitalizations with lengths of stay of 0 and 1 night were designated as "high turnover." Serial cross-sectional analyses were conducted to compare the proportion of high-turnover stays across and within years according to patient and hospital-level characteristics. Diagnosis-related groups and hospital charges associated with these observation-length stays were examined.

RESULTS

In 2003, there were an estimated 441 363 high-turnover hospitalizations compared with 388 701 in 1993. The proportion of high-turnover stays increased from 24.9% in 1993 to 29.9% in 1999 and has remained >/=30.0% since that time. Diagnosis-related groups for high-turnover stays reflect common pediatric medical and surgical conditions requiring hospitalization, including respiratory illness, gastrointestinal/metabolic disorders, seizure/headache, and appendectomy. Significant increases in the proportion of high-turnover stays during the study period were noted across patient and hospital-level characteristics, including age group, payer, hospital location, teaching status, bed size, and admission source. High-turnover stays contributed $1.3 billion (22%) to aggregate hospital charges in 2003, an increase from $494 million (12%) in 1993.

CONCLUSIONS

Consistently since 1999, nearly one third of children hospitalized in the United States experience a high-turnover stay. These high-turnover cases constitute hospitalizations, that may be eligible for care in an alternative setting. Observation units provide 1 model for an efficient and cost-effective alternative to inpatient care, in which resources and provider interactions with patients and each other are geared toward shorter stays with more timely discharge processes.

Modification by influenza on health effects of air pollution in Hong Kong

BACKGROUND

Both influenza viruses and air pollutants have been well documented as major hazards to human health, but few epidemiologic studies have assessed effect modification of influenza on health effects of ambient air pollutants.

OBJECTIVES

We aimed to assess modifying effects of influenza on health effects of ambient air pollutants.

METHODS

We applied Poisson regression to daily numbers of hospitalizations and mortality to develop core models after adjustment for potential time-varying confounding variables. We assessed modification of influenza by adding variables for concentrations of single ambient air pollutants and proportions of influenza-positive specimens (influenza intensity) and their cross-product terms.

RESULTS

We found significant effect modification of influenza (p < 0.05) for effects of ozone. When influenza intensity is assumed to increase from 0% to 10%, the excess risks per 10-microg/m(3) increase in concentration of O(3) increased 0.24% and 0.40% for hospitalization of respiratory disease in the all-ages group and >or= 65 year age group, respectively; 0.46% for hospitalization of acute respiratory disease in the all-ages group; and 0.40% for hospitalization of chronic obstructive pulmonary disease in the >or= 65 group. The estimated increases in the excess risks for mortality of respiratory disease and chronic obstructive pulmonary disease in the all-ages group were 0.59% and 1.05%, respectively. We found no significant modification of influenza on effects of other pollutants in most disease outcomes under study.

CONCLUSIONS

Influenza activity could be an effect modifier for the health effects of air pollutants particularly for O(3) and should be considered in the studies for short-term effects of air pollutants on health.

Pediatric stroke in the United States and the impact of risk factors

One approach to studying pediatric stroke is to analyze a national database that contains data on a significant number of children. We examined an administrative dataset of hospital discharges from the United States, Kids' Inpatient Database 2003 (KID2003), for ICD-9 codes associated with hemorrhagic or ischemic stroke in children aged >30 days to 20 years. 3156 children were discharged with a diagnosis of ischemic stroke and 2022 with hemorrhagic stroke after statistical weighting. The odds for a male discharged with hemorrhagic stroke was 1.5 (CI: 1.35-1.68) and for ischemic stroke was 1.37 (CI: 1.24-1.51) compared with a female. The odds for males discharged with a stroke were greatest for ages 16 to 20 years and least for 4 years. This study confirms a male predominance for stroke. The odds for hospitalization with a stroke diagnosis are greatest in very young and older adolescent males. Hemorrhage is an important stroke subtype in children.

The 2006 California heat wave: impacts on hospitalizations and emergency department visits

BACKGROUND

Climate models project that heat waves will increase in frequency and severity. Despite many studies of mortality from heat waves, few studies have examined morbidity.

OBJECTIVES

In this study we investigated whether any age or race/ethnicity groups experienced increased hospitalizations and emergency department (ED) visits overall or for selected illnesses during the 2006 California heat wave.

METHODS

We aggregated county-level hospitalizations and ED visits for all causes and for 10 cause groups into six geographic regions of California. We calculated excess morbidity and rate ratios (RRs) during the heat wave (15 July to 1 August 2006) and compared these data with those of a reference period (8-14 July and 12-22 August 2006).

RESULTS

During the heat wave, 16,166 excess ED visits and 1,182 excess hospitalizations occurred statewide. ED visits for heat-related causes increased across the state [RR = 6.30; 95% confidence interval (CI), 5.67-7.01], especially in the Central Coast region, which includes San Francisco. Children (0-4 years of age) and the elderly (> or = 65 years of age) were at greatest risk. ED visits also showed significant increases for acute renal failure, cardiovascular diseases, diabetes, electrolyte imbalance, and nephritis. We observed significantly elevated RRs for hospitalizations for heat-related illnesses (RR = 10.15; 95% CI, 7.79-13.43), acute renal failure, electrolyte imbalance, and nephritis.

CONCLUSIONS

The 2006 California heat wave had a substantial effect on morbidity, including regions with relatively modest temperatures. This suggests that population acclimatization and adaptive capacity influenced risk. By better understanding these impacts and population vulnerabilities, local communities can improve heat wave preparedness to cope with a globally warming future.

Clinical outcomes in pediatric hemodialysis patients in the USA: lessons from CMS' ESRD CPM Project

Although prospective randomized trials have provided important information and allowed the development of evidence-based guidelines in adult hemodialysis (HD) patients, with approximately 800 prevalent pediatric HD patients in the United States, such studies are difficult to perform in this population. Observational data obtained through the Center for Medicare & Medicaid Services' (CMS') End Stage Renal Disease (ESRD) Clinical Performance Measures (CPM) Project have allowed description of the clinical care provided to pediatric HD patients as well as identification of risk factors for failure to reach adult targets for clinical parameters such as hemoglobin, single-pool Kt/V (spKt/V) and serum albumin. In addition, studies linking data from the ESRD CPM Project and the United States Renal Data System have allowed evaluation of associations between achievement of those targets and the outcomes of hospitalization and death. The results of those studies, while unable to prove cause and effect, suggest that the adult ESRD CPM targets may assist in identifying pediatric HD patients at risk for poor outcomes.

Acute decompensated heart failure: contemporary medical management

Hospitalizations for acute decompensated heart failure are increasing in the United States. Moreover, the prevalence of heart failure is increasing consequent to an increased number of older individuals, as well as to improvement in therapies for coronary artery disease and sudden cardiac death that have enabled patients to live longer with cardiovascular disease. The main treatment goals in the hospitalized patient with heart failure are to restore euvolemia and to minimize adverse events. Common in-hospital treatments include intravenous diuretics, vasodilators, and inotropic agents. Novel pharmaceutical agents have shown promise in the treatment of acute decompensated heart failure and may simplify the treatment and reduce the morbidity associated with the disease. This review summarizes the contemporary management of patients with acute decompensated heart failure.

Differences in COPD-related readmissions to primary and secondary care hospitals

OBJECTIVE

To study differences in readmissions to primary and secondary care hospitals for exacerbations of chronic obstructive pulmonary disease (COPD).

DESIGN

A register-based study.

SUBJECTS

The data were gathered from the hospital admissions register of the Finnish National Research and Development Centre for Welfare and Health. The data included all acute periods of treatment received by COPD patients aged over 44 years in 1996-2004 who had a principal or subsidiary diagnosis of COPD (ICD 10: J41-J44), respiratory infection (ICD 10: J00-J39, J85-J86) or cardiac insufficiency (ICD 10: I50), followed by an emergency readmission. Treatment had to have taken place in either a primary care hospital or a specialized ward for respiratory diseases or internal medicine in a secondary care hospital.

MAIN OUTCOME MEASURES

The risk of readmission within a week of discharge, analysed by site of care.

RESULTS

The risk of readmission within seven days of discharge is 1.74-fold for a patient treated in primary care compared with a patient treated in secondary care.

CONCLUSIONS

COPD patients discharged from primary care hospitals have a greater risk of readmission, particularly within a week, than those discharged from secondary care. This risk may be attributed to differences in treatment procedures and arrangement of subsequent care. Thus, in the future, more attention should be paid to primary healthcare resources and staff training.

Prognostication in acutely admitted older patients by nurses and physicians

BACKGROUND

The process of prognostication has not been described for acutely hospitalized older patients.

OBJECTIVE

To investigate (1) which factors are associated with 90-day mortality risk in a group of acutely hospitalized older medical patients, and (2) whether adding a clinical impression score of nurses or physicians improves the discriminatory ability of mortality prediction.

DESIGN

Prospective cohort study.

PARTICIPANTS

Four hundred and sixty-three medical patients 65 years or older acutely admitted from November 1, 2002, through July 1, 2005, to a 1024-bed tertiary university teaching hospital.

MEASUREMENTS

At admission, the attending nurse and physician were asked to give a clinical impression score for the illness the patient was admitted for. This score ranged from 1 (high possibility of a good outcome) until 10 (high possibility of a bad outcome, including mortality). Of all patients baseline characteristics and clinical parameters were collected. Mortality was registered up to 90 days after admission.

MAIN RESULTS

In total, 23.8% (n = 110) of patients died within 90 days of admission. Four parameters were significantly associated with mortality risk: functional impairment, diagnosis malignancy, co-morbidities and high urea nitrogen serum levels. The AUC for the baseline model which included these risk factors (model 1) was 0.76 (95% CI 0.71 to 0.82). The AUC for the model using the risk factors and the clinical impression score of the physician (model 2) was 0.77 (0.71 to 0.82). The AUC for the model using the risk factors and the clinical impression score of the nurse (model 3) was 0.76 (0.71 to 0.82) and the AUC for the model, including the baseline covariates and the clinical impression score of both nurses and physicians was 0.77 (0.72 to 0.82). Adding clinical impression scores to model 1 did not significantly improve its accuracy.

CONCLUSION

A set of four clinical variables predicted mortality risk in acutely hospitalized older patients quite well. Adding clinical impression scores of nurses, physicians or both did not improve the discriminating ability of the model.

Japanese haemodialysis anaemia management practices and outcomes (1999-2006): results from the DOPPS

BACKGROUND

Japanese haemodialysis (HD) patients not only have a very low mortality and hospitalization risk but also low haemoglobin (Hb) levels. Internationally, anaemia is associated with mortality, hospitalization and health-related quality of life (QoL) measures of HD patients.

METHODS

Longitudinal data collected from 1999 to 2006 from 60 to 64 representative Japanese dialysis units participating in the Dialysis Outcomes and Practice Patterns Study (DOPPS) were used to describe anaemia management practices and outcomes for Japanese HD patients.

RESULTS

From 1999 to 2006, patient mean Hb increased from 9.7 g/dl to 10.4 g/dl, and the percentage of facilities with median Hb >or=10 g/dl increased from 27% to 75%. Hb was measured in the supine position for 90% of patients, resulting in substantially lower reported Hb values than those seen in other countries. As of 2006, erythropoietin (Epo) was prescribed to 83% of HD patients; mean Epo dose was 5231 units/week; intravenous (IV) iron use was 33% and median IV iron dose was 160 mg/month. Many patient- and facility-level factors were significantly related to higher Hb. A consistent overall pattern of lower mortality risk with higher baseline Hb levels was seen (RR = 0.89 per 1 g/dl higher Hb, P = 0.003). Facilities with median Hb >or=10.4 displayed a lower mortality risk (RR = 0.77, P = 0.03) versus facility median Hb <10.4 g/dl. Lower Hb levels were not significantly related to hospitalization risk, but were associated with lower QoL scores.

CONCLUSIONS

These results provide detailed information on anaemia management practices in Japan and the relationships of anaemia control with outcomes, with implications of anaemia management worldwide.

Acute care utilization by dementia caregivers within urban primary care practices

BACKGROUND

Caring for an individual with Alzheimer's dementia (AD) is stressful, and studies show that this stress has an impact on both the physical and mental health of the caregiver. However, many questions remain about the characteristics of AD patients and their caregivers that contribute to this stress and how it impacts caregivers' use of healthcare resources.

OBJECTIVE

To study the impact of stress on the physical and mental health of the caregiver.

DESIGN

Patients underwent extensive testing to allow description of their degree of cognitive impairment, behavioral and psychological symptoms, medical comorbidities, and functional abilities. Caregivers were assessed for depressive symptoms and also for emergency department (ED) use and hospitalizations in the previous six months. Multivariate logistic regression was used to evaluate impact of patients' dementia symptoms on caregivers' acute care utilization.

PARTICIPANTS

One hundred and fifty-three AD patients and their caregivers attending two large, urban, university-affiliated primary care practices were enrolled in a cross-sectional study to examine the facets of dementia caregiving that impact caregiver acute health care utilization.

RESULTS

Twenty-four percent of the caregivers had at least one ED visit or hospitalization in the six months prior to enrollment. After adjusting for caregiver age, gender, and education, our logistic regression model found that the caregivers' acute care utilization was associated with their depression as measured by the PHQ-9 (OR 1.09, 95% CI 1.00-1.18), the patients' behavioral and psychological symptoms as measured by the NPI (OR 1.04, 95% CI 1.01-1.08), and the patients' functional status as measured by the ADCS-ADL (OR 1.05, 95% CI 1.01-1.09).

CONCLUSION

To improve the health of AD caregivers, a primary care system needs to reallocate resources to manage the functional, behavioral, and psychological symptoms related to the care-recipients suffering from AD.

Admission avoidance hospital at home

BACKGROUND

Admission avoidance hospital at home is a service that provides active treatment by health care professionals in the patient's home for a condition that otherwise would require acute hospital in-patient care, and always for a limited time period. In particular, hospital at home has to offer a specific service to patients in their home requiring health care professionals to take an active part in the patients' care. If hospital at home were not available then the patient would be admitted to an acute hospital ward. Many countries are adopting this type of care in an attempt to reduce the demand for acute hospital admission.

OBJECTIVES

To determine, in the context of a systematic review and meta analysis, the effectiveness and cost of managing patients with admission avoidance hospital at home compared with in-patient hospital care.

SEARCH STRATEGY

The following databases were searched through to January 2008: MEDLINE, EMBASE, CINAHL, EconLit and the Cochrane Effective Practice and Organisation of Care Group (EPOC) register. We checked the reference lists of articles identified electronically for evaluations of hospital at home and obtained potentially relevant articles. Unpublished studies were sought by contacting providers and researchers who were known to be involved in this field.

SELECTION CRITERIA

Randomised controlled trials recruiting patients aged 18 years and over. Studies comparing admission avoidance hospital at home with acute hospital in-patient care. The admission avoidance hospital at home interventions may admit patients directly from the community thereby avoiding physical contact with the hospital, or may admit from the emergency room.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data and assessed study quality. Our statistical analyses sought to include all randomised patients and were done on an intention to treat basis. We requested individual patient data (IPD) from trialists, and relied on published data when we did not receive trial data sets or the IPD did not include the relevant outcomes. When combining outcome data was not possible because of differences in the reporting of outcomes we have presented the data in narrative summary tables.For the IPD meta-analysis, where at least one event was reported in both study groups in a trial, Cox regression models were used to calculate the log hazard ratio and its standard error for mortality and readmission separately for each data set (where both outcomes were available). We included randomisation group (admission avoidance hospital at home versus control), age (above or below the median), and gender in the models. The calculated log hazard ratios were combined using fixed effects inverse variance meta analysis. If there were no events in one group we used the Peto odds ratio method to calculate a log odds ratio from the sum of the log-rank test 'O-E' statistics from a Kaplan Meier survival analysis. Statistical significance throughout was taken at the two-sided 5% level (p<0.05) and data are presented as the estimated effect with 95% confidence intervals. For each comparison using published data for dichotomous outcomes we calculated risk ratios using a fixed effects model to combine data.

MAIN RESULTS

We included 10 RCTs (n=1333), 7 of which were eligible for the IPD. Five out of these seven trials contributed to the IPD meta-analysis (n=850/975; 87%). There was a non significant reduction in mortality at three months for the admission avoidance hospital at home group (adjusted HR 0.77, 95% CI 0.54 to 1.09; p=0.15), which reached significance at six months follow-up (adjusted HR 0.62, 95% CI 0.45 to 0.87; p=0.005). A non significant increase in admissions was observed for patients allocated to hospital at home (adjusted HR 1.49, 95% CI 0.96 to 2.33; p=0.08). Few differences were reported for functional ability, quality of life or cognitive ability. Patients reported increased satisfaction with admission avoidance hospital at home. Two trials conducted a full economic analysis, when the costs of informal care were excluded admission avoidance hospital at home was less expensive than admission to an acute hospital ward.

AUTHORS' CONCLUSIONS

We performed meta-analyses where there was sufficient similarity among the trials and where common outcomes had been measured. There is no evidence from the analysis to suggest that admission avoidance hospital at home leads to outcomes that differ from inpatient hospital care.

One-year respiratory outcomes of preterm infants enrolled in the Nitric Oxide (to prevent) Chronic Lung Disease trial

OBJECTIVE

To identify whether inhaled nitric oxide treatment decreased indicators of long-term pulmonary morbidities after discharge from the neonatal intensive care unit.

STUDY DESIGN

The Nitric Oxide (to Prevent) Chronic Lung Disease trial enrolled preterm infants (<1250 g) between 7 to 21 days of age who were ventilated and at high risk for bronchopulmonary dysplasia. Follow-up occurred at 12 +/- 3 months of age adjusted for prematurity; long-term pulmonary morbidity and other outcomes were reported by parents during structured blinded interviews.

RESULTS

A total of 456 infants (85%) were seen at 1 year. Compared with control infants, infants randomized to inhaled nitric oxide received significantly less bronchodilators (odds ratio [OR] 0.53 [95% confidence interval 0.36-0.78]), inhaled steroids (OR 0.50 [0.32-0.77]), systemic steroids (OR 0.56 [0.32-0.97]), diuretics (OR 0.54 [0.34-0.85]), and supplemental oxygen (OR 0.65 [0.44-0.95]) after discharge from the neonatal intensive care unit. There were no significant differences between parental report of rehospitalizations (OR 0.83 [0.57-1.21]) or wheezing or whistling in the chest (OR 0.70 [0.48-1.03]).

CONCLUSIONS

Infants treated with inhaled nitric oxide received fewer outpatient respiratory medications than the control group. However, any decision to institute routine use of this dosing regimen should also take into account the results of the 24-month neurodevelopmental assessment.

Providers' perceptions of relationships and professional roles when caring for patients who leave the hospital against medical advice

BACKGROUND

Patients who leave hospitals against medical advice (AMA) may be at risk for adverse health outcomes. Their decision to leave may not be clearly understood by providers. This study explored providers' experiences with and attitudes toward patients who leave the hospital AMA.

OBJECTIVE

To explore providers' experiences with and attitudes toward patients who leave the hospital AMA.

METHODS

We conducted interviews with university-based internal medicine residents and practicing internal medicine clinicians caring for patients at a community hospital from July 2006 to August 2007. We approached 34 providers within 3 days of discharging a patient AMA. The semi-structured instrument elicited perceptions of care, emotions, and challenges faced when caring for patients who leave AMA. Using an editing analysis style, investigators independently coded transcripts, agreeing on the coding template and its application.

PARTICIPANTS

All 34 providers (100%) participated. Providers averaged 32.6 years of age, 22 (61%) were men, 20 (59%) were housestaff from three residency programs, 13 (38%) were faculty, hospitalist physicians, or chief residents serving as ward attendings, and one (3%) was a physician assistant.

MAIN RESULTS

Four themes emerged: 1) providers' beliefs that patients lack insight into their medical conditions; 2) suboptimal communication, mistrust, and conflict; 3) providers' attempts to empathize with patients' concerns; and 4) providers' professional roles and obligations toward patients who leave AMA.

CONCLUSION

Our study revealed that patients who leave AMA influence providers' perceptions of their patients' insight, and their own patient-provider communication, empathy for patients, and professional roles and obligations. Future research should investigate educational interventions to optimize patient-centered communication and support providers in their decisional conflicts when these challenging patient-provider discussions occur.

Hospital malnutrition and inflammatory response in critically ill children and adolescents admitted to a tertiary intensive care unit

Critical illness has a major impact on the nutritional status of both children and adults. A retrospective study was conducted to evaluate the incidence of hospital malnutrition at a pediatric tertiary intensive care unit (PICU). Serum concentrations of IL-6 in subgroups of well-nourished and malnourished patients were also evaluated in an attempt to identify those with a potential nutritional risk.

METHODS

A total of 1077 patients were enrolled. Nutritional status was evaluated by Z-score (weight for age). We compared mortality, sepsis incidence, and length of hospital stay for nourished and malnourished patients. We had a subgroup of 15 patients with severe malnutrition (MN) and another with 14 well-nourished patients (WN). Cytokine IL-6 determinations were performed by enzyme-linked immunosorbent assay.

RESULTS

53% of patients were classified with moderate or severe malnutrition. Similar amounts of C- reactive protein (CRP) were observed in WN and MN patients. Both groups were able to increase IL-6 concentrations in response to inflammatory systemic response and the levels followed a similar evolution during the study. However, the mean values of serum IL-6 were significantly different between WN and MN patients across time, throughout the study (p = 0.043).

DISCUSSION

a considerable proportion of malnourished patients need specialized nutritional therapy during an intensive care unit (ICU) stay. Malnutrition in children remains largely unrecognized by healthcare workers on admission.

CONCLUSIONS

The incidence of malnutrition was very high. Malnourished patients maintain the capacity to release inflammatory markers such as CRP and IL-6, which can be considered favorable for combating infections On the other hand, this capacity might also have a significant impact on nutritional status during hospitalization.

Impact of quality circles for improvement of asthma care: results of a randomized controlled trial

RATIONALE AND AIMS

Quality circles (QCs) are well established as a means of aiding doctors. New quality improvement strategies include benchmarking activities. The aim of this paper was to evaluate the efficacy of QCs for asthma care working either with general feedback or with an open benchmark.

METHODS

Twelve QCs, involving 96 general practitioners, were organized in a randomized controlled trial. Six worked with traditional anonymous feedback and six with an open benchmark; both had guided discussion from a trained moderator. Forty-three primary care practices agreed to give out questionnaires to patients to evaluate the efficacy of QCs.

RESULTS

A total of 256 patients participated in the survey, of whom 185 (72.3%) responded to the follow-up 1 year later. Use of inhaled steroids at baseline was high (69%) and self-management low (asthma education 27%, individual emergency plan 8%, and peak flow meter at home 21%). Guideline adherence in drug treatment increased (P = 0.19), and asthma steps improved (P = 0.02). Delivery of individual emergency plans increased (P = 0.008), and unscheduled emergency visits decreased (P = 0.064). There was no change in asthma education and peak flow meter usage. High medication guideline adherence was associated with reduced emergency visits (OR 0.24; 95% CI 0.07-0.89). Use of theophylline was associated with hospitalization (OR 7.1; 95% CI 1.5-34.3) and emergency visits (OR 4.9; 95% CI 1.6-14.7). There was no difference between traditional and benchmarking QCs.

CONCLUSIONS

Quality circles working with individualized feedback are effective at improving asthma care. The trial may have been underpowered to detect specific benchmarking effects. Further research is necessary to evaluate strategies for improving the self-management of asthma patients.

Nursing home characteristics related to medicare costs for residents with and without dementia

OBJECTIVES

To evaluate the relationship of nursing home characteristics to Medicare costs overall and by dementia status.

DESIGN

New admissions followed for 2 years. Setting. Random stratified sample of 55 Maryland nursing homes.

PARTICIPANTS

Sample of 1257 residents.

MEASURES

Records, interview, and observation.

RESULTS

Medicare costs were lower in facilities that have a better environmental quality, hospice beds, and more food service workers; costs were higher in hospital-based facilities and those that have a higher Medicaid case mix, X-ray, and some specified types of staff. Across all characteristics, costs for residents with dementia were consistently two-thirds the cost of other residents.

DISCUSSION

In terms of dementia status, resident characteristics drive Medicare costs, as opposed to facility characteristics. Using alternative residential settings for individuals with dementia may increase Medicare costs of nursing home residents and Medicare costs of residents with dementia who are cared for in settings less able to attend to medical needs.

Admission rates of patients with borderline personality disorder in a psychiatric unit in a General Hospital

This study examined the admission rates of patients with borderline personality disorder in a psychiatric unit within a General Hospital. The medical records of patients with DSM-IV borderline personality disorder who were admitted to the unit during the years 2004 and 2005 were retrospectively reviewed. The number of admissions of patients with borderline personality disorder was 78, involving 48 patients. The mean of admissions were 1.63 per patient. The comparison to the rest of the patient population (922 patients with a total of 1086 admissions) demonstrated that patients with borderline personality disorder were admitted more frequently than patients with major psychiatric disorders. The difference was statistically significant (P=0.042). The main reasons for admission were suicide attempts or threats and lack of out-patient facilities. The introduction of out-patient psychiatric facilities may contribute to the reduction of the admissions and to the better management of the disorder.

Screening of older community-dwelling people at risk for death and hospitalization: the Assistenza Socio-Sanitaria in Italia project

OBJECTIVES

To develop and validate mortality and hospitalization prognostic tools based upon information readily available to primary care physicians (PCPs).

DESIGN

Population-based cohort study. Baseline predictors were patient demographics, a seven-item questionnaire on functional status and general health, use of five or more drugs, and previous hospitalization.

SETTING

Community-based study.

PARTICIPANTS

Prognostic indexes were developed in 2,470 subjects and validated in 2,926 subjects, all community-dwelling, aged 65 and older, and randomly sampled from the rosters of 98 PCPs in Florence, Italy.

MEASUREMENTS

Fifteen-month mortality and hospitalization.

RESULTS

Two scores were derived from logistic regression models and used to stratify participants into four groups. With Model 1, based upon the seven-item questionnaire, mortality rate ranged from 0.8% in the lowest-risk group (0-1 point) to 9.4% in the highest risk group (> or = 3 points), and hospitalization rate ranged from 12.4% to 29.3%; area under the receiver operating characteristic curves (AUC) was 0.75 and 0.60, respectively. With Model 2, considering also drug use and previous hospitalization, mortality and hospitalization rates ranged from 0.3% to 8.2% and from 8.1% to 29.7%, for the lowest-risk to the highest-risk group; the AUC increased significantly only for hospitalization (0.67).

CONCLUSION

Prediction of death and hospitalization in older community-dwelling people can be easily obtained with two indexes using information promptly available to PCPs. These tools might be useful for guiding clinical care and targeting interventions to reduce the need for hospital care in older persons.

Discharge destination from an acute care for the elderly (ACE) unit

Older adults age 65 and over account for a disproportional number of hospital stays and discharges compared to other age groups. The objective of this paper is to describe placement and characteristics of older patients discharged from an acute care for the elderly (ACE) unit. The study sample consists of 1,351 men and women aged 65 years or older that were discharged from the ACE Unit during a 12-month period. The mean number of discharges per month was 109.2 +/- 28.4. Most of the subjects were discharged home or home with home health 841, 62.3%. The oldest elderly and patients who had been admitted from long-term care institutions or from skilled nursing facilities to the ACE unit were less likely to return to home.

Hospital Outcomes of Adult Respiratory Tract Infections with Extended-Spectrum B-Lactamase (ESBL) Producing Klebsiella Pneumoniae

Klebsiella pneumoniae ranks high as a cause of adult pneumonia requiring hospitalization in Malaysia. To study whether extended-spectrum b-lactamase (ESBL) producing K. pneumoniae was linked to hospital outcomes, we retrospectively studied 441 cases of adult respiratory tract infections with microbial proven K. pneumoniae from an urban-based university teaching hospital between 2003 and 2004. 47 (10.6%) cases had ESBL. Requirement for ventilation and median length of hospital stay, were greater in 'ESBL' than in 'non-ESBL' group [34% vs. 7.4%, p<0.001; 14 days vs. 5 days, p<0.001 respectively] but not crude hospital mortality rate [21.3% vs. 12.4%, p=0.092]. There was a four-fold increased risk of requiring ventilation [4.61 (2.72-7.85)] when ESBL was present. Our findings support the association of ESBL producing K. pneumoniae with adversed hospital outcomes and reiterate the need for vigilance on the part of treating clinicians.

Anticoagulation control in the peri-hospitalization period

Oral anticoagulants (OAC) are effective and safe if the international normalized ratio (INR) is maintained within a narrow therapeutic range. Hospitalization is independently associated with poor anticoagulation control. The objective of this study is to describe how anticoagulation control changes in the peri-hospitalization period. This study is a retrospective cohort study using population-based administrative databases. INR results were retrieved from a population-based laboratory database. INR levels between laboratory measures were estimated using linear interpolation. Auto-regressive, integrated, moving average (ARIMA) time-series modeling was used to determine how anticoagulation control changed in the peri-hospitalization period. The study included 5,380 elderly patients in Eastern Ontario between 1 September 1999 and 1 September 2000 taking OACs. Results showed that 951 (17.7%) were hospitalized during their OAC therapy [thrombotic, n = 52 (1.0%); hemorrhagic, n = 140 (2.6%); other hospitalization types, n = 759 (14.1%)]. All measures of anticoagulation control changed significantly in the peri-hospitalization period. Before hemorrhagic admissions, mean INR and proportion with INR > 5 increased significantly (daily increase 0.024, P = .03 and 0.2%, P = .01). Following other hospitalization types, the proportion of patients with INR < 1.5 was significantly increased (daily increase 0.19%, P = .02). Patients admitted to the hospital for a variety of indications have significantly worse anticoagulation control in the peri-hospitalization period. Anticoagulated patients discharged after medical hospitalizations could be targeted for improved anticoagulation control.

A captive audience: a pilot study of screening and counseling hospitalized women for fracture risk

BACKGROUND

Innovative methods are needed to improve screening for osteoporosis, especially in women with multiple comorbid conditions.

OBJECTIVES

Determine whether a fracture risk-screening program including a bedside calcaneal ultrasound is feasible in hospitalized women, and determine whether identification of fracture risks results in behavior change after discharge.

DESIGN

Prospective uncontrolled feasibility study.

SETTING

Five hundred twenty-eight bed academic hospital.

PARTICIPANTS

One hundred three hospitalized women age 60 years or older.

METHODS

A bedside calcaneal ultrasound was used to estimate bone mineral density. Clinical fracture risks were obtained via interview. The patient and primary care physician received personalized risk information and educational material.

RESULTS

Of 103 eligible women, 59 (57%) agreed to undergo bedside screening and counseling. Of these 59 women, 49 (83%) had at least one major clinical risk factor for fracture. The median T-score was -2.5. Among the 42 women available for phone follow-up 2 months after hospital discharge, 34 (81%) reported after at least 1 recommendation to diminish fracture risk.

CONCLUSION

A hospital-based osteoporosis screening program using calcaneal ultrasound is feasible and identifies women at risk of fracture. Feedback of low bone mineral density and fracture risk during hospitalization may promote behavior change to diminish fracture risk after discharge.

A population-based study of hospital admission incidence rate and bacterial aetiology of acute lower respiratory infections in children aged less than five years in Bangladesh

The research was carried out to study the rate of population-based hospital admissions due to acute lower respiratory infections (ALRIs) and bacterial aetiology of ALRIs in children aged less than five years in Bangladesh. A cohort of children aged less than five years in a rural surveillance population in Matlab, Bangladesh, was studied for two years. Cases were children admitted to the Matlab Hospital of ICDDR,B with a diagnosis of severe ALRIs. Bacterial aetiology was determined by blood culture. Antimicrobial resistance patterns of Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae (Spn) isolates were determined using the disc-diffusion method. In total, 18,983 children aged less than five years contributed to 24,902 child-years of observation (CYO). The incidence of ALRI-related hospital admissions was 50.2 per 1,000 CYO. The incidences of ALRI were 67% higher in males than in females and were higher in children aged less than two years than in older children. About 34% of the cases received antibiotics prior to hospitalization. Of 840 blood samples cultured, 39.4% grew a bacterial isolate; 11.3% were potential respiratory pathogens, and the rest were considered contaminants. The predominant isolates were Staphylococcus aureus (4.5%). Hib (0.4%) and Spn (0.8%) were rarely isolated; however, resistance of both these pathogens to trimethoprim-sulphamethoxazole was common. The rate of ALRI-related hospitalizations was high. The high rate of contamination, coupled with high background antibiotic use, might have contributed to an underestimation of the burden of Hib and Spn. Future studies should use more sensitive methods and more systematically look for resistance patterns of other pathogens in addition to Hib and Spn.

Characteristics of nondisabled older patients developing new disability associated with medical illnesses and hospitalization

OBJECTIVE

To identify demographic, clinical, and biological characteristics of older nondisabled patients who develop new disability in basic activities of daily living (BADL) during medical illnesses requiring hospitalization.

DESIGN

Longitudinal observational study.

SETTING

Geriatric and Internal Medicine acute care units.

PARTICIPANTS

Data are from 1,686 patients aged 65 and older who independent in BADL 2 weeks before hospital admission, enrolled in the 1998 survey of the Italian Group of Pharmacoepidemiology in the Elderly Study.

MEASUREMENTS

Study outcome was new BADL disability at time of hospital discharge. Sociodemographic, functional status, and clinical characteristics were collected at hospital admission; acute and chronic conditions were classified according to the International Classification of Disease, ninth revision; fasting blood samples were obtained and processed with standard methods.

RESULTS

At the time of hospital discharge 113 patients (6.7%) presented new BADL disability. Functional decline was strongly related to patients' age and preadmission instrumental activities of daily living status. In a multivariate analysis, older age, nursing home residency, low body mass index, elevated erythrocyte sedimentation rate, acute stroke, high level of comorbidity expressed as Cumulative Illness Rating Scale score, polypharmacotherapy, cognitive decline, and history of fall in the previous year were independent and significant predictors of BADL disability.

CONCLUSION

Several factors might contribute to loss of physical independence in hospitalized older persons. Preexisting conditions associated with the frailty syndrome, including physical and cognitive function, comorbidity, body composition, and inflammatory markers, characterize patients at high risk of functional decline.

Predisposing factors of complicated deep neck infection: an analysis of 158 cases

Both the introduction of antibiotics and improvements in oral hygiene have made deep neck infections occur less frequently today than in the past. Nevertheless, the complications from these infections are often life-threatening. The purpose of this article was to review the clinical findings of deep neck infections and identify the predisposing factors of these complications. The present study reviewed 158 cases of deep neck infections between the years of 1995 to 2004, 23 of which had life-threatening complications. Cases were excluded if they had peritonsillar abscesses, superficial infections, infections related to external neck wounds, or head and neck tumors. The authors used multiple linear regression and the logistic regression analysis in order to determine the clinical parameters that are associated with longer hospitalizations and complicated deep neck infections, respectively. The multiple linear regression showed that patients with a large number of involved spaces, diabetes mellitus, and complications required longer hospitalizations (p < 0.05). The logistic regression showed that patients with more than two involved spaces were more likely to have complicated deep neck infections (p < 0.05). Patients with odontogenic causes had negative correlation (p < 0.05). We recommend that high-risk groups, such as diabetic patients and/or patients with more than two involved spaces, should be more closely monitored throughout their hospitalization.

Mother and baby units for schizophrenia

BACKGROUND

Mother and baby units (MBUs) are recommended, in the UK, as an optimal site for treating post partum psychoses. Naturalistic studies suggest poor outcomes for mothers and their children if admission is needed during the first year after birth, but the evidence for the effectiveness of MBUs in addressing the problems faced by both mothers with mental illness and their babies is unclear.

OBJECTIVES

To review the effects of mother and baby units for mothers with schizophrenia or psychoses needing admission during the first year after giving birth, and their children, in comparison to standard care on a ward without a mother and baby unit.

SEARCH STRATEGY

We undertook electronic searches of the Cochrane Schizophrenia Group's Register (June 2006).

SELECTION CRITERIA

We included all randomised clinical trials comparing placement on a mother and baby unit compared to any other standard care without attachment to such a unit.

DATA COLLECTION AND ANALYSIS

If data were available we would have independently extracted data and analysed on an intention-to treat basis; calculated the relative risk (RR) and 95% confidence intervals (CI) of homogeneous dichotomous data using a random effects model, and where possible calculated the number needed to treat (NNT); calculated weighted mean differences (WMD) for continuous data.

MAIN RESULTS

Unfortunately, we did not find any relevant studies to include. One non-randomised trial, published in 1961, suggested beneficial effects for those admitted to mother and baby units. For the experimental group, more women were able to care for their baby on their own and experienced fewer early relapses on their return home compared with standard care. Care practices for people with schizophrenia have changed dramatically over the past 40 years and a sensitively designed pragmatic trial is possible and justified.

AUTHORS' CONCLUSIONS

Mother and bay units are reportedly common in the UK but less common in other countries and rare or non-existent in the developing world. However, there does not appear to be any trial-based evidence for the effectiveness of these units. This lack of data is of concern as descriptive studies have found poor outcomes such as anxious attachment and poor development for children of mothers with schizophrenia and a greater risk of the children being placed under supervised or foster care. Effective care of both mothers and babies during this critical time may be crucial to prevent poor clinical and parenting outcomes. Good, relevant research is urgently needed.

Low parental literacy is associated with worse asthma care measures in children

OBJECTIVE

To determine whether parental literacy is related to emergency department visits, hospitalizations, and days of school missed for children with asthma.

METHODS

We performed a retrospective cohort study at a university pediatric clinic. We enrolled children between 3 and 12 years old with a diagnosis of asthma and a regular source of care at the site of the study and their parent or guardian. Primary asthma care measures included self-reported rates of emergency department visits, hospitalizations, and days of school missed. Secondary asthma care measures included rescue and controller medication use, classification of asthma severity, and parental asthma-related knowledge.

RESULTS

We enrolled 150 children and their parents. Twenty-four percent of the parents had low literacy. Children of parents with low literacy had greater incidence of emergency department visits (adjusted incidence rate ratio [IRR] 1.4; 95% confidence interval 0.97, 2.0), hospitalizations (IRR 4.6; 1.8, 12), and days missed from school (IRR 2.8; 2.3, 3.4) even after adjusting for asthma-related knowledge, disease severity, medication use, and other sociodemographic factors. Parents with low literacy had less asthma-related knowledge, and their children were more likely to have moderate or severe persistent asthma and had greater use of rescue medications.

CONCLUSIONS

Low parental literacy is associated with worse care measures for children with asthma.

Comparison of return of bowel function and length of stay in patients undergoing laparoscopic versus open colectomy

BACKGROUND

Over the last decade, many advances have been made in laparoscopic techniques in various surgical specialties. The technique of laparoscopic-assisted colectomy (LAC) has been reported since 1992 and has been slowly gaining popularity in the surgical community. Several studies have compared laparoscopic versus open colectomy, assessing its applicability to patients with colon cancer, Crohn's disease, and diverticular disease. Studies to date have assessed length of stay, operative time, and clinical outcome. This study focuses on return of bowel function and length of hospital stay in patients undergoing LAC compared with those undergoing open colectomy.

METHODS

We performed a retrospective review of patients undergoing either open colon resection or LAC between January 2000 and December 2005. All disease processes and both emergent and elective cases were included. Return of bowel function was determined by passage of flatus or first passage of stool and compared between the 2 groups. The data were statistically analyzed using the Student t test for interval data, and nominal data were analyzed using the chi-square analysis (95% confidence interval; CI).

RESULTS

The study included 247 patients; 179 (72.5%) underwent open colectomy and 68 (27.5%) underwent LAC. Passage of flatus took 3.6 days (95% CI .18 or 3.4 to 3.8) for open colectomy, and 2.9 days (95% CI .19 or 2.7 to 3.1) for LAC. First bowel movement took 4.4 days (95% CI .19 or 4.2 to 4.6) for open colectomy and 3.7 days (95% CI .22 or 3.5 to 3.9) for LAC. When compared between the groups, mean length of hospital stay was 8.01 days (95% CI .93 or 7.1 to 8.9) for open colectomy and 4.38 days (95% CI .38 or 4.0 to 4.8) for LAC.

CONCLUSION

Both return of bowel function and length of stay were statistically significantly shorter in LAC compared with those in open colectomy, which may indicate faster recovery after bowel surgery in patients undergoing the laparoscopic approach.

Brief report: incidence, etiology, risk factors, and outcome of hospital-acquired fever: a systematic, evidence-based review

OBJECTIVES

Temperature is universally measured in the hospitalized patient, but the literature on hospital-acquired fever has not been systematically reviewed. This systematic review is intended to provide clinicians with an overview of the incidence, etiology, and outcome of hospital-acquired fever.

DATA SOURCES

We searched MEDLINE (1970 to 2005), EMBASE (1988 to 2004), and Web of Knowledge. References of all included articles were reviewed. Articles that focused on children, fever in the developing world, classic fever of unknown origin, or specialized patient populations were excluded.

REVIEW METHODS

Articles were reviewed independently by 2 authors before inclusion; a third author acted as arbiter.

RESULTS

Of over 1,000 studies reviewed, 7 met the criteria for inclusion. The incidence of hospital-acquired fever ranged from 2% to 17%. The etiology of fever was infection in 37% to 74%. Rates of antibiotic use for patients with a noninfectious cause of fever ranged from 29% to 55% for a mean duration of 6.6 to 9.6 days. Studies varied widely in their methodology and the patient population studied.

CONCLUSIONS

Limited information is available to guide an evidence-based approach to hospital-acquired fever. We propose criteria to help standardize future studies of this important clinical situation.

Which family factors predict children's externalizing behaviors following discharge from psychiatric inpatient treatment?

OBJECTIVE

Parents' behavior management practices, parental stress, and family environment are highly pertinent to children's conduct problems. Preadolescents' psychiatric hospitalization usually arises because of severe conduct problems, so the relationships of family-related variables to postdischarge functioning warrant investigation. This study examined postdischarge clinical course and select family factors to model outcomes via a) predictors measured at admission, b) predictors measured concurrently with outcome, and c) changes in predictor values from admission through follow-up.

METHOD

In a prospective follow-up of 107 child psychiatry inpatients, caregivers completed rating scales pertaining to their child's behavior, parenting practices, parenting stress, caregiver strain, and their own psychological distress at admission and three, six, and 12 months after discharge.

RESULTS

The magnitude of reductions in parenting stress between admission and follow-up bore the strongest relationship to improvements in externalizing behavior. The largest and most sustained decreases in externalizing behavior arose among youngsters whose parents reported high parenting stress at admission and low parenting stress after discharge. By contrast, children whose parents reported low parenting stress at admission and follow-up showed significantly less postdischarge improvement. Parenting stress changes were not attributable to changes in behavioral symptoms. Parenting stress eclipsed relationships between behavior management practices and child outcomes, suggesting that parenting stress might have a mediational role.

CONCLUSIONS

High initial parenting stress disposed to better outcomes over the year of follow-up. Consistently low stress predicted less improvement. Higher stress at admission may imply more advantageous parent-child relationships or motivation for subsequent persistence with treatment. Interventions that ameliorate high stress may warrant further study. Low parenting stress might signify disengagement, or, alternatively, that parents of some chronically impaired children become rather inured to fluctuations in behavioral problems. If confirmed, further examination of these and other accounts for a relationship between low parenting stress and suboptimal child outcome seems warranted.

Portrait of outpatient visits and hospitalizations for acute infections in Nunavik preschool children

OBJECTIVE

Inuit children from around the world are burdened by a high rate of infectious diseases. The objective of this study was to evaluate the incidence rate of infections in Inuit preschool children from Nunavik (Northern Québec).

METHODS

The medical chart of 354 children from a previously recruited cohort was reviewed for the first five years of life. All outpatient visits that led to a diagnosis of acute infection and all admissions for acute infections were recorded.

RESULTS

Rates of outpatient visits for acute otitis media (AOM) were 2314, 2300, and 732 events/1000 child-years for children 0-11 months, 12-23 months, and 2-4 years, respectively. Rates of outpatient visits for lower respiratory tract infections (LRTI) were 1385, 930, and 328 events/1000 child-years, respectively. Rates of hospitalization for pneumonia were 198, 119, and 31 events/1000 child-years, respectively.

CONCLUSION

Inuit children from Nunavik have high rates of AOM and LRTI. Such rates were higher than that of other non-native North-American populations previously published. Admission for LRTI is up to 10 times more frequent in Nunavik compared to other Canadian populations.

Medical injuries among hospitalized children

BACKGROUND

Inpatient medical injuries among children are common and result in a longer stay in hospital and increased hospital charges. However, previous studies have used screening criteria that focus on inpatient occurrences only rather than on injuries that also occur in ambulatory or community settings leading to hospital admission.

OBJECTIVE

To describe the incidence and outcomes of medical injuries among children hospitalized in Wisconsin using the Wisconsin Medical Injury Prevention Program (WMIPP) screening criteria.

METHODS

Cross sectional analysis of discharge records of 318,785 children from 134 hospitals in Wisconsin between 2000 and 2002.

RESULTS

The WMIPP criteria identified 3.4% of discharges as having one or more medical injuries: 1.5% due to medications, 1.3% to procedures, and 0.9% to devices, implants and grafts. After adjusting for the All Patient Refined-Diagnosis Related Groups disease category, illness severity, mortality risk, and clustering within hospitals, the mean length of stay (LOS) was a half day (12%) longer for patients with medical injuries than for those without injuries. The similarly adjusted mean total hospital charges were 1614 dollars (26%) higher for the group with medical injuries. Excess LOS and charges were greatest for injuries due to genitourinary devices/implants, vascular devices, and infections/inflammation after procedures.

CONCLUSIONS

This study reinforces previous national findings up to 2000 using Wisconsin data to the end of 2002. The results suggest that hospitals and pediatricians should focus clinical improvement on medications, procedures, and devices frequently associated with medical injuries and use medical injury surveillance to track medical injury rates in children.

Fluctuation of psychological status in burn patients during hospitalization

This paper considers the fluctuations in psychological status that occur in burn patients in the acute phase, during hospitalization, and in the post-hospitalization period. The various disorders are reported. Psychiatric consultation is mandatory, along with psychological support, and appropriate medication should be prescribed.

Symptom control, functioning, and hospitalization status in French patients changed from oral atypical antipsychotics to risperidone long-acting injectable

Objective. To investigate efficacy and tolerability of risperidone long-acting injectable (RLAI) in French patients with schizophrenia or other psychotic disorders, who were all switching from previous treatment with oral atypical antipsychotics. The impact of treatment with RLAI on the hospitalization status of these patients was also examined. Methods. Clinically stable patients requiring a treatment change received 25 mg RLAI (increased to 37.5 or 50 mg if required) every 2 weeks for 6 months. Results. Of 130 patients (68.5% male, mean age 36.2 years), most (83.8%) had DSM-IV schizophrenia (mainly paranoid). Previous treatments were risperidone (80.8%), olanzapine (10.0%) and amisulpride (10.0%). Out of 66 patients hospitalized at baseline, 51 were outpatients at endpoint. Mean total PANSS, CGI-S and GAF scores were significantly reduced from baseline to treatment endpoint (p<0.001). Of those patients reported as moderate to severely ill at the beginning of the trial (81.3%), fewer had the same classification at endpoint (50.8%). Mean scores for total ESRS and Parkinsonism subscales were significantly reduced after only 1 month of treatment (p<0.001). Conclusion. Treatment with RLAI significantly improved disease symptoms, functioning, hospitalization status, and reduced movement disorders, in psychotic patients considered clinically stable on oral atypical antipsychotics.

Digoxin and reduction in mortality and hospitalization in heart failure: a comprehensive post hoc analysis of the DIG trial

AIMS

To determine the effects of digoxin on all-cause mortality and heart failure (HF) hospitalizations, regardless of ejection fraction, accounting for serum digoxin concentration (SDC).

METHODS AND RESULTS

This comprehensive post-hoc analysis of the randomized controlled Digitalis Investigation Group trial (n=7788) focuses on 5548 patients: 1687 with SDC, drawn randomly at 1 month, and 3861 placebo patients, alive at 1 month. Overall, 33% died and 31% had HF hospitalizations during a 40-month median follow-up. Compared with placebo, SDC 0.5-0.9 ng/mL was associated with lower mortality [29 vs. 33% placebo; adjusted hazard ratio (AHR), 0.77; 95% confidence interval (CI), 0.67-0.89], all-cause hospitalizations (64 vs. 67% placebo; AHR, 0.85; 95% CI, 0.78-0.92) and HF hospitalizations (23 vs. 33% placebo; AHR, 0.62; 95% CI, 0.54-0.72). SDC> or =1.0 ng/mL was associated with lower HF hospitalizations (29 vs. 33% placebo; AHR, 0.68; 95% CI, 0.59-0.79), without any effect on mortality. SDC 0.5-0.9 reduced mortality in a wide spectrum of HF patients and had no interaction with ejection fraction >45% (P=0.834) or sex (P=0.917).

CONCLUSIONS

Digoxin at SDC 0.5-0.9 ng/mL reduces mortality and hospitalizations in all HF patients, including those with preserved systolic function. At higher SDC, digoxin reduces HF hospitalization but has no effect on mortality or all-cause hospitalizations.

Ineffective communication of mental status information during care transfer of older adults

BACKGROUND

Monitoring and documenting the mental status of older patients transferred between providers or facilities is important because mental status change can be a sign of acute disease and mental status abnormalities necessitate specific approaches to care.

OBJECTIVES

To identify patient and illness factors associated with presence of a mental status description in inter-facility transfer documents and to describe the content and concurrent validity of transfer mental status descriptions when they occur.

DESIGN

Retrospective study.

PARTICIPANTS

Individuals transferred between 5 long-term and 2 acute care facilities in an urban setting.

MEASUREMENTS

Trained research personnel reviewed hospital and nursing home medical records and inter-facility transfer documents. Mental status descriptions in transfer documents were coded as abnormal or normal within 5 domains: alertness, communication, orientation/memory, behavior, and mood. Descriptions were compared with mental status items in the nursing home Minimum Data Set and in a transfer communication checklist.

RESULTS

In all, 123 nursing home residents experienced 174 hospital admissions. Mental status descriptions were present in 69% of transfer documents. A total of 67% of patients missing a transfer mental status description upon nursing home-to-hospital transfer had dementia. Factors associated with presence of a transfer mental status description were urgent transfer, nursing home of origin, and among patients without dementia, greater cognitive impairment. When present, a mean of 1.47 (SD=0.81) cognitive domains were documented in transfer mental status descriptions. Agreement between transfer mental status descriptions and comparison sources was fair to good (kappa=.31 to .73).

CONCLUSION

Mental status documentation during transfer of older adults between nursing home and hospital did not identify all patients with dementia and did not completely characterize patients' cognitive status.

An approach to maximizing treatment adherence of children and adolescents with psychotic disorders and major mood disorders

INTRODUCTION

Mental health research has consistently focused on high rates of treatment non-adherence, and how inpatient programs and health professionals can effectively confront this reality. The literature has centred almost exclusively on adult populations. Unfortunately, psychotic and major mood disorders are serious and persistent mental health problems that are increasingly recognized as having an early onset, affecting children and adolescents.

METHOD

This article draws on a review of the literature and Habermas's three domains of knowledge: technical, practical, and emancipatory. This article has incorporated current research, adherence theories, and the facilitation of the unique local expertise of health professionals to generate a framework. This framework is designed to teach health professionals working in child and adolescent psychiatric inpatient units how they and the larger unit can practice to enhance patient treatment adherence during and after admission.

RESULTS

A five-step approach to teach health professionals to enhance treatment adherence has been developed based on current research and educational theories and principles.

CONCLUSION

Health professionals working in child and adolescent psychiatry can practice to enhance patient treatment adherence, and improve patient and family outcomes.

Patient reports of undesirable events during hospitalization

BACKGROUND

Thus far, incident reporting in health care has relied on health professionals. However, patients too may be able to signal the occurrence of undesirable events.

OBJECTIVE

To estimate the frequency of undesirable events reported by recently discharged patients, and to identify correlates of undesirable events.

DESIGN

Mailed patient survey.

SETTING

Swiss public teaching hospital.

PARTICIPANTS

Adult patients (N=1,518) discharged from hospital.

MEASUREMENTS

Self-reports of 27 undesirable events during hospitalization, including 9 medical complications, 9 interpersonal problems, and 9 incidents related to the health care process.

RESULTS

Most survey respondents (1,433, 94.4%) completed the section about undesirable events, and 725 (50.6%) reported at least 1 event. The most frequent events were phlebitis (11.0%), unavailable medical record (9.5%), failure to respect confidentiality (8.4%), and hospital-acquired infection (8.2%). The odds of an unfavorable rating increased with each additional interpersonal problem (odds ratio [OR] 1.6, 95% confidence interval [CI] 1.3 to 1.8), each additional process-related problem (OR 1.5, 95% CI 1.3 to 1.9), but not with each additional medical complication (OR 1.0, 95% CI 0.9 to 1.2). Longer duration of stay, poor health, and depressed mood were all related to a greater reported frequency of undesirable events.

CONCLUSION

Patients are able to report undesirable events that occur during hospital care. Such events occur in about a half of the hospitalizations, and have a negative impact on satisfaction with care.

Physician visits, hospitalizations, and socioeconomic status: ambulatory care sensitive conditions in a canadian setting

OBJECTIVE

To determine whether rates of physician visits for ambulatory care sensitive (ACS) conditions are lower for people of low-socioeconomic status than of high-socioeconomic status in an urban population with universal health care coverage.

DATA SOURCES/STUDY SETTING

Physician claims and hospital discharge abstracts from fiscal years 1998 to 2001 for urban residents of Manitoba, Canada. The 1996 Canadian Census public use database provided neighborhood household income information. The study included all continuously enrolled urban residents in the Manitoba Health Services Insurance Plan.

STUDY DESIGN

Twelve ACS conditions definable using 3-digit ICD-9-CM codes permitted cross-sectional and longitudinal comparison of ambulatory visits and hospitalizations. Neighborhood household income data provided a measure of socioeconomic status.

DATA COLLECTION/EXTRACTION METHODS

Files were extracted from administrative data housed at the Manitoba Centre for Health Policy.

PRINCIPAL FINDINGS

All conditions showed a socioeconomic gradient with residents of the lowest income neighborhoods having both more visits and more hospitalizations than their counterparts in higher income areas. Six of nine conditions with a sufficient N showed individuals living in the lowest income neighborhoods to have significantly more ambulatory visits before hospitalization for an ACS condition than did those in the most affluent neighborhoods. Many conditions showed a gradient in rate of hospitalization even after controlling for the number of ambulatory care visits.

CONCLUSIONS

In the Canadian universal health care plan, the poor have reasonable access to ambulatory care for ACS conditions. Ambulatory care may be more effective in preventing hospitalizations among relatively affluent individuals than among the less well off.
