Health insurance and length of stay for children hospitalized with community-acquired pneumonia

Racial and Ethnic Differences in Length of Stay for US Children Hospitalized for Acute Osteomyelitis

OBJECTIVE

To examine the associations between race and ethnicity and length of stay (LOS) for US children with acute osteomyelitis.

STUDY DESIGN

Using the Kids' Inpatient Database, we conducted a cross-sectional study of children <21 years old hospitalized in 2016 or 2019 with acute osteomyelitis. Using survey-weighted negative binomial regression, we modeled LOS by race and ethnicity, adjusting for clinical and hospital characteristics and socioeconomic status. Secondary outcomes included prolonged LOS, defined as LOS of >7 days (equivalent to LOS in the highest quartile).

RESULTS

We identified 2388 children discharged with acute osteomyelitis. The median LOS was 5 days (IQR, 3-7). Compared with White children, children of Black race (adjusted incidence rate ratio [aIRR] 1.15; 95% CI, 1.05-1.27), Hispanic ethnicity (aIRR 1.11; 95% CI, 1.02-1.21), and other race and ethnicity (aIRR 1.12; 95% CI, 1.01-1.23) had a significantly longer LOS. The odds of Black children experiencing prolonged LOS was 46% higher compared with White children (aOR, 1.46; 95% CI, 1.01-2.11).

CONCLUSIONS

Children of Black race, Hispanic ethnicity, and other race and ethnicity with acute osteomyelitis experienced longer LOS than White children. Elucidating the mechanisms underlying these race- and ethnicity-based differences, including social drivers such as access to care, structural racism, and bias in provision of inpatient care, may improve management and outcomes for children with acute osteomyelitis.

Caregiver Inclusivity and Empowerment During Family-Centered Rounds

OBJECTIVE

Despite widespread adoption of family-centered rounds, few have investigated differences in the experience of family-centered rounds by family race and ethnicity. The purpose of this study was to explore racial and ethnic differences in caregiver perception of inclusion and empowerment during family-centered rounds.

METHODS

We identified eligible caregivers of children admitted to the general pediatrics team through the electronic health record. Surveys were completed by 99 caregivers (47 non-Latinx White and 52 Black, Latinx, or other caregivers of color). To compare agreement with statements of inclusivity and empowerment, we used the Wilcoxon rank sum test in unadjusted analyses and linear regression for the adjusted analyses.

RESULTS

Most (91%) caregivers were satisfied or extremely satisfied with family-centered rounds. We found no differences by race or ethnicity in statements of satisfaction or understanding family-centered rounds content. However, in both unadjusted and adjusted analyses, we found that White caregivers more strongly agreed with the statements "I felt comfortable participating in rounds," "I had adequate time to ask questions during rounds," and "I felt a valued member of the team during rounds" compared with Black, Latinx, and other caregivers of color.

CONCLUSIONS

Congruent with studies of communication in other settings, caregivers of color may experience barriers to inclusion in family-centered rounds, such as medical team bias, less empathic communication, and shorter encounters. Future studies are needed to better understand family-centered rounds disparities and develop interventions that promote inclusive rounds.

Impact of insurance status, hospital ownership type, and children's hospital designation on outcomes for pediatric neurosurgery patients following spasticity procedures in the USA

PURPOSE

This study aims to examine the relationship between insurance status, hospital ownership type, and children's hospital designation with outcomes for pediatric patients undergoing neurosurgical treatment for spasticity.

METHODS

This retrospective cohort study utilized the Healthcare Cost and Utilization Project Kids' Inpatient Database and included 11,916 pediatric patients (≤ 17 years of age) who underwent neurosurgical treatment for spasticity between 2006 and 2012 using ICD-9-CM procedure codes.

RESULTS

Uninsured patients had a significantly shorter hospital length of stay compared to Medicaid patients (-1.42 days, P = 0.030) as did privately insured patients (-0.74 days; P = 0.035). Discharge disposition and inpatient mortality rate were not associated with insurance status. There were no significant associations with hospital ownership type. Free-standing children's hospitals retained patients significantly longer compared to non-children's hospitals (+1.48 days; P = 0.012) and had a significantly higher likelihood of favorable discharge disposition (P = 0.004). Mortality rate was not associated with children's hospital designation.

CONCLUSION

Pediatric patients undergoing neurosurgical treatment for spasticity were more likely to stay in the hospital longer if they were insured by Medicaid or treated in a free-standing children's hospital. In addition, patients in free standing children's hospitals were more likely to be discharged with a favorable disposition.

Predictors of Prolonged Length of Stay in Suicidal Children Transferred to Psychiatric Facilities

OBJECTIVES

To determine if sociodemographic factors or underlying mental health conditions serve as predictors for prolonged length of stay (pLOS) in children hospitalized for suicidal ideation (SI) or suicide attempt (SA) requiring transfer to psychiatric facilities. We hypothesized an association between certain patient and hospital characteristics and pLOS.

METHODS

For this retrospective cross-sectional study, we used the National Inpatient Sample. We included children <18 years old hospitalized with a primary or secondary International Classification of Diseases, 10th Edition, Clinical Modification diagnosis of SI or SA who were dispositioned to psychiatric facilities from 2016 to 2017. Exposures were patient sociodemographics, underlying mental health diagnoses, and hospital characteristics. Our outcome was pLOS. Adjusted prevalence ratios with 95% confidence intervals (CIs) were generated with log binomial regression.

RESULTS

Of 12 715 hospitalizations meeting inclusion criteria, 5475 had pLOS. After adjusting for sociodemographics and hospital characteristics, predictive factors for pLOS were public insurance use (prevalence ratio: 1.40; CI: 1.12-1.78), urban nonteaching hospital location (prevalence ratio: 4.61; CI: 2.33-9.12), urban teaching hospital location (prevalence ratio: 3.26; CI: 1.84-5.76), and underlying diagnosis of mood disorder (prevalence ratio: 1.98; CI: 1.63-3.42). Hispanic patients had decreased probability of pLOS (prevalence ratio: 0.69; CI: 0.52-0.93). Otherwise, age, zip income, sex, and hospital region were not predictive of pLOS.

CONCLUSIONS

Among children hospitalized for SI or SA requiring transfer to psychiatric facilities, public insurance, urban hospital location, and diagnoses of mood disorder, depression, and bipolar disorder were predictive of pLOS. Further research is needed on how to decrease disparities in length of stay among this vulnerable population.

Identifying Modifiable Health Care Barriers to Improve Health Equity for Hospitalized Children

BACKGROUND

Children from socially disadvantaged families experience worse hospital outcomes compared with other children. We sought to identify modifiable barriers to care to target for intervention.

METHODS

We conducted a prospective cohort study of hospitalized children over 15 months. Caregivers completed a survey within 3 days of admission and 2 to 8 weeks after discharge to assess 10 reported barriers to care related to their interactions within the health care system (eg, not feeling like they have sufficient skills to navigate the system and experiencing marginalization). Associations between barriers and outcomes (30-day readmissions and length of stay) were assessed by using multivariable regression. Barriers associated with worse outcomes were then tested for associations with a cumulative social disadvantage score based on 5 family sociodemographic characteristics (eg, low income).

RESULTS

Of eligible families, 61% (n = 3651) completed the admission survey; of those, 48% (n = 1734) completed follow-up. Nine of 10 barriers were associated with at least 1 worse hospital outcome. Of those, 4 were also positively associated with cumulative social disadvantage: perceiving the system as a barrier (adjusted β = 1.66; 95% confidence interval [CI] 1.02 to 2.30), skill barriers (β = 3.82; 95% CI 3.22 to 4.43), cultural distance (β = 1.75; 95% CI 1.36 to 2.15), and marginalization (β = .71; 95% CI 0.30 to 1.11). Low income had the most consistently strong association with reported barriers.

CONCLUSIONS

System barriers, skill barriers, cultural distance, and marginalization were significantly associated with both worse hospital outcomes and social disadvantage, suggesting these are promising targets for intervention to decrease disparities for hospitalized children.

Effects of Hospital Practice Patterns for Antibiotic Administration for Pneumonia on Hospital Lengths of Stay and Costs

BACKGROUND

Hospital practice patterns vary for switching from intravenous to oral antibiotics for community-acquired pneumonia in pediatric patients, but it is unknown how these practice patterns affect hospital lengths of stay and costs.

METHODS

We conducted a retrospective study of 78673 pediatric patients (aged 3 months to 17 years) hospitalized for community-acquired pneumonia. Analyses were performed with data from the Pediatric Health Information System between 2007 and 2016, including discharge data from 48 freestanding children's hospitals. Patients who received antibiotics used to treat aspiration pneumonia and patients with a complex chronic condition were excluded to focus the study on uncomplicated cases. We modeled hospital practice patterns using hospital-level averages for the last day of service on which patients received antibiotics intravenously or first day of service on which patients received antibiotics orally.

RESULTS

We found that a 1-day decrease in the hospital-level average last day of service on which a patient received antibiotics intravenously reduced the average length of stay by 0.58 day (95% confidence interval [CI], -0.69 to -0.47 day) and average cost by $1332 (95% CI, -$2363 to -$300). Results were similar when hospital practice patterns were modeled using the average first day of service on which a patient received antibiotics orally. These reductions in lengths of stay and costs were not associated with a difference in 30-day readmission rates.

CONCLUSIONS

Given the reductions in lengths of stay and costs without sacrificing patient outcomes (readmissions), antimicrobial stewardship programs could target provider education on the duration of intravenous antibiotic therapy as a way to reduce resource utilization.

Health Disparities in the Hospitalized Child

Health care disparities exist along the continuum of care for children admitted to the hospital; they start before admission, impact hospital course, and continue after discharge. During an acute illness, risk of admission, length of stay, hospital costs, communication during family-centered rounds, and risk of readmission have all been shown to vary by socioeconomic status, race, and ethnicity. Understanding factors beyond the acute illness that increase a child's risk of admission, increase hospital course complications, and lower discharge quality is imperative for the new generation of pediatric hospitalists focused on improving health for a population of children. In this article, we describe a framework to conceptualize socioeconomic, racial, and ethnic health disparities for the hospitalized child. Additionally, we offer actions pediatric hospitalists can take to address disparities within their practices.

Hospitalization Rate and Population-based Incidence of Hospitalization for Community-acquired Pneumonia Among Children in Suzhou, China

BACKGROUND

Data on hospitalization burden of community-acquired pneumonia (CAP) in children are very limited in China. This study aimed to estimate the hospitalization rate (HR) and population-based incidence of hospitalization of CAP for children <15 years of age in Suzhou, China.

METHODS

This was a retrospective study of children hospitalized in Soochow University Affiliated Children's Hospital from January 2010 to December 2014. Children who were residents of downtown Suzhou, 29 days to <15 years of age, with discharge diagnosis codes (International Classification of Diseases, 10th revision) including J09-J18 and J20-J22 were included. All-cause clinical community-acquired pneumonia (CCAP) and radiographically confirmed pneumonia (RCAP) were identified based on individual medical chart review. The HR and population-based cumulative incidence of hospitalization (HI) were calculated.

RESULTS

Among 184,734 children <15 years of age admitted to Soochow University Affiliated Children's Hospital during the study period, 31,302 children were identified as having CCAP and 24,218 (77.4%) children confirmed as having RCAP. CCAP hospitalization occurred year round and peaked during winter and early spring. The overall HRs for CCAP and RCAP were 189.0 [95% confidence interval (CI): 187.1-190.9] and 146.2 (95% CI: 144-148) per 1000 hospitalizations, respectively, and the HIs per 100,000 children annually were CCAP, 3235.8 (95% CI: 3207.3-3264.2) and RCAP, 2503.5 (95% CI: 2478.3-2528.6). For children <5 years of age, the HR for CCAP was 248.4 (95% CI: 245.9-250.9) and RCAP was 194.0 (95% CI: 191.4-196.3) per 1000 hospitalizations; the HI for CCAP was 6956.2 (95% CI: 6892.8-7019.6) and 5431.9 (95% CI: 5375.4-5488.4) per 100,000 children for RCAP. The highest HR and HI were observed in children 29 days to <6 months of age: HR for CCAP was 407.4 (95% CI: 400.9-413.9) per 1000 hospitalizations and HI for CCAP was 11,203.7 (95% CI: 11,026.8-11,380.6) per 100,000 children annually.

CONCLUSIONS

There is a considerable burden of CAP among children <15 years of age in Suzhou, particularly among children 29 days to <6 months of age and during winter and early spring. These data provide valuable information to monitor CAP trends over time in children of Suzhou, China.

Race, Income and Insurance Status Affect Neonatal Sepsis Mortality and Healthcare Resource Utilization

BACKGROUND

Socioeconomic disparities negatively impact neonatal health. The influence of sociodemographic disparities on neonatal sepsis is understudied. We examined the association of insurance payer status, income, race and gender on neonatal sepsis mortality and healthcare resource utilization.

METHODS

We used the Kid's Inpatient Database, a nationwide population-based survey from 2006, 2009 and 2012. Neonates diagnosed with sepsis were included in the study. Multivariable logistic regression (mortality) and multivariable linear regression (length of stay and total hospital costs) were constructed to determine the association of patient and hospital characteristics.

RESULTS

Our study cohort included a weighted sample of 160,677 septic neonates. Several sociodemographic disparities significantly increased mortality. Self-pay patients had increased mortality (odds ratio 3.26 [95% confidence interval: 2.60-4.08]), decreased length of stay (-2.49 ± 0.31 days, P < 0.0001) and total cost (-$5015.50 ± 783.15, P < 0.0001) compared with privately insured neonates. Additionally, low household income increased odds of death compared with the most affluent households (odds ratio 1.19 [95% confidence interval: 1.05-1.35]). Moreover, Black neonates had significantly decreased length of stay (-0.86 ± 0.25, P = 0.0005) compared with White neonates.

CONCLUSIONS

This study identified specific socioeconomic disparities that increased odds of death and increased healthcare resource utilization. Moreover, this study provides specific societal targets to address to reduce neonatal sepsis mortality in the United States.

Risk factors for hospitalizations due to bacterial respiratory tract infections after tracheotomy

OBJECTIVE

Identify characteristics associated with hospital readmission due to bacterial respiratory tract infections (bRTI) after tracheotomy.

STUDY DESIGN

Retrospective study of 8009 children 0-17 years undergoing tracheotomy from 2007 to 2013 at 48 children's hospitals in the Pediatric Health Information System database. The primary outcome was first hospital admission after tracheotomy for bRTI (ie, primary diagnosis of bRTI or a primary diagnosis of bRTI symptom and secondary diagnosis of bRTI). We used Cox-proportional hazard modeling to assess associations between patient demographic and clinical characteristics and bRTI hospital readmission.

RESULTS

Median age at tracheotomy admission was 5 months (interquartile range [IQR]: 1-50 months). Thirty-six percent (n = 2899) had at least one bRTI admission. Median time-to-readmission for bRTI was 275 days (IQR: 141-530). Factors independently associated with increased risk for bRTI readmission were younger age (eg, age < 30 days vs 13-17 years [aHR 1.32; 95%CI: 1.11-1.58]), Hispanic race/ethnicity (vs non-Hispanic White; aHR: 1.34; 95%CI: 1.20-1.50), government insurance (vs private; aHR 1.21; 95%CI: 1.10-1.33), >2 complex chronic conditions (vs zero; aHR 1.96; 95%CI: 1.34-2.86) and discharge to home (vs post-acute care setting; aHR 1.19; 95%CI: 1.08-1.32). Trauma diagnosis at tracheotomy (aHR 0.83; 95%CI: 0.69-1) and ventilator dependency (aHR 0.88; 95%CI: 0.81-0.97) were associated with decreased risk.

CONCLUSIONS

Young, Hispanic children with multiple complex chronic conditions who use Medicaid insurance and are not discharged to post-acute care are at the highest risk for hospital readmission for bRTI post-tracheotomy. Future research should investigate strategies to mitigate this risk for these children.

Length of Stay and Hospital Revisit After Bacterial Tracheostomy-Associated Respiratory Tract Infection Hospitalizations

OBJECTIVES

To identify factors associated with longer length of stay (LOS) and higher 30-day hospital revisit rates for children hospitalized with bacterial tracheostomy-associated respiratory tract infections (bTARTIs).

METHODS

This was a multicenter, retrospective cohort study using administrative data from the Pediatric Health Information System database between 2007 and 2014 of patients 30 days to 17 years old with a principal discharge diagnosis of bTARTI or a principal discharge diagnosis of bTARTI symptoms with a secondary diagnosis of bTARTI. Primary outcomes of LOS (in days) and 30-day all-cause revisit rates (inpatient, observation, or emergency department visit) were analyzed by using a 3-level hierarchical regression model (discharges within patients within hospital).

RESULTS

We included 3715 unique patients and 7355 discharges. The median LOS was 4 days (interquartile range: 3-8 days), and the 30-day revisit rate was 30.5%. Compared with children 1 to 4 years old, children aged 30 days to 12 months had both longer LOS (adjusted length of stay [aLOS] = +0.9 days; 95% confidence interval [CI]: 0.6 to 1.3) and increased hospital revisit risk (adjusted odds ratio [aOR] = 1.5; 95% CI: 1.3 to 1.7). Other factors associated with longer LOS included public insurance (aLOS = +0.5 days; 95% CI: 0.2 to 0.8), 3 or more complex chronic conditions (CCCs), mechanical ventilation (acute or chronic), and empirical anti-Pseudomonas aeruginosa antibiotics (aLOS = +0.6 days; 95% CI: 0.3 to 0.9). Other factors associated with 30-day revisit included 4 or more CCCs (aOR = 1.3; 95% CI: 1.1 to 1.6) and chronic ventilator dependency (aOR = 1.1; 95% CI: 1.0 to 1.3).

CONCLUSIONS

Ventilator-dependent patients <12 months old with at least 4 CCCs are at highest risk for both longer LOS and 30-day revisit after discharge for bTARTIs. They may benefit from bTARTI prevention strategies and intensive care coordination while hospitalized.

A nationwide study of children and adolescents with pneumonia who visited Emergency Department in South Korea in 2012

Purpose

Acute respiratory infection, particularly pneumonia, is the most common cause of hospitalization and death among children in developing nations. This study aimed to investigate the characteristics of children and adolescents with pneumonia who visited Emergency Department (ED) in South Korea in 2012.

Methods

We analyzed National Emergency Department Information System (NEDIS) records from 146 EDs in South Korea for all pediatric patients aged ≤18 years who were diagnosed with pneumonia between January and December 2012.

Results

Among 38,415 subjects, the male-to-female ratio was 1:0.8. Patients aged <12 months comprised 18.0% of the study population; those aged 1 to 3 years, 54.4%; those aged 4 to 6 years, 16.8%; those aged 7 to 12 years, 7.4%; and those aged 13 to 18 years, 3.4%. Presentation rates were highest in April, followed by January, March, and May. The hospital admission rate was 43.5%, of which 2.6% were in intensive care units. The mortality rate was 0.02%. Based on the International Classification of Diseases, 10th Revision, diagnostic codes, the types of pneumonia according to cause were viral pneumonia (29.0%), bacterial pneumonia (5.3%), Mycoplasmal pneumonia (4.5%), aspiration pneumonia (1.3%), and pneumonia of unknown origin (59.3%).

Conclusion

Despite the limited data due to the ED data from the NEDIS lacking laboratory results and treatment information, this study reflects well the outbreak patterns among children and adolescents with pneumonia. Our results provide a basis for future studies regarding ED treatment for children and adolescents with pneumonia.

Does Using Complementary Health Insurance Affect Hospital Length of Stay? Evidence from Acute Coronary Syndrome Patients

BACKGROUND

Length of stay (LOS) is used as an indicator to show the efficacy of hospitals. An increase in hospitalized days is not cost effective and decreases the efficacy of hospitals. Using insurance has some side effects. One of these side effects is increasing the LOS. In this study we attempt to discover the effects of complementary health insurance (CHI) on LOS in patients with acute coronary syndrome (ACS).

METHODS

In this cross-sectional study, 260 patients were surveyed. By using Poisson regression, the effects of using complementary health insurance on LOS were examined. The effects of confounders were also controlled in the model.

RESULTS

The results of this study demonstrated that the relationship between use of CHI and LOS is direct. In addition, an increase in age and income also increases the LOS. The average LOS was 4.13 days, while it was 5.31 for CHI users, and 3.81 for CHI nonusers.

CONCLUSION

Government budget is restricted and ACS treatments are costly. Decreasing LOS in ACS patients can help to spend the budget more effectively.

Risk Factors for Prolonged Length of Stay or Complications During Pediatric Respiratory Hospitalizations

BACKGROUND AND OBJECTIVES

Respiratory illnesses are the leading cause of pediatric hospitalizations in the United States, and a major focus of efforts to improve quality of care. Understanding factors associated with poor outcomes will allow better targeting of interventions for improving care. The objective of this study was to identify patient and hospital factors associated with prolonged length of stay (LOS) or complications during pediatric hospitalizations for asthma or lower respiratory infection (LRI).

METHODS

Cross-sectional study of hospitalizations of patients <18 years with asthma or LRI (bronchiolitis, influenza, or pneumonia) by using the nationally representative 2012 Kids Inpatient Database. We used multivariable logistic regression models to identify factors associated with prolonged LOS (>90th percentile) or complications (noninvasive ventilation, mechanical ventilation, or death).

RESULTS

For asthma hospitalizations(n = 85 320), risks for both prolonged LOS and complications were increased with each year of age (adjusted odds ratio [AOR] 1.06, 95% confidence interval [CI] 1.05-1.07; AOR 1.05, 95% CI 1.03-1.07, respectively for each outcome) and in children with chronic conditions (AOR 4.87, 95% CI 4.15-5.70; AOR 21.20, 95% CI 15.20-29.57, respectively). For LRI hospitalizations (n = 204 950), risks for prolonged LOS and complications were decreased with each year of age (AOR 0.98, 95% CI 0.97-0.98; AOR 0.95, 95% CI 0.94-0.96, respectively) and increased in children with chronic conditions (AOR 9.86, 95% CI 9.03-10.76; AOR 56.22, 95% CI 46.60-67.82, respectively). Risks for prolonged LOS for asthma were increased in large hospitals (AOR 1.67, 95% CI 1.32-2.11) and urban-teaching hospitals (AOR 1.62, 95% CI 1.33-1.97).

CONCLUSIONS

Older children with asthma, younger children with LRI, children with chronic conditions, and those hospitalized in large urban-teaching hospitals are more vulnerable to prolonged LOS and complications. Future research and policy efforts should evaluate and support interventions to improve outcomes for these high-risk groups (eg, hospital-based care coordination for children with chronic conditions).

Increasing hospitalizations in inflammatory bowel disease among children in the United States, 1988-2011

BACKGROUND

Our objective was to characterize national trends in inflammatory bowel disease (IBD)-related hospitalizations for children. We hypothesized that over time, improvements in care would be associated with a decrease in hospitalization rates, similar to what has been observed in Canadian children with IBD.

METHODS

Retrospective, serial, cross-sectional analysis of annual, nationally representative samples of children with IBD.

RESULTS

Overall, discharges for all children irrespective of diagnosis decreased from 1988 to 2011 (P for trend <0.001). In contrast, discharges for children with IBD rose over the same time period from 6.1 (95% confidence interval [CI], 4.0-8.2) to 8.2 (95% CI, 5.5-10.9) per 100,000 individuals per year (P for trend <0.001). More of this rise occurred in hospitalizations that did not have IBD-related endoscopy or surgery performed (P for trend <0.001). Although mean length of stay decreased over the study period (P for trend <0.001), total hospital days increased over the latter half of the study with a significant increase over the entire study period (P for trend <0.001).

CONCLUSIONS

Contrary to clinically informed hypotheses, nationally representative rates of hospitalization for pediatric patients with IBD have increased since the mid-1990s. This directly contrasts with stable rates over the preceding years. Most of the expansion in hospital care seems to be related to hospitalizations that do not include procedures. Several lines of future research may greatly facilitate a better understanding of the epidemiologic, therapeutic, and health care resource issues at play.

Management and outcomes of pneumonia among children with complex chronic conditions

INTRODUCTION

Although pneumonia is a common reason for pediatric hospitalization among children with complex chronic conditions (CCC), treatment and outcomes have not been well-described. We characterized the presentation, management and outcomes of pneumonia in children with and without CCC and described how antibiotic management and outcomes vary among subgroups of children with CCC.

METHODS

We conducted a cohort study of children <18 years with pneumonia across a large sample of US hospitals. Children were grouped according to CCC subgroups. Differences in disease management and outcomes were assessed using multivariable regression.

RESULTS

Of the 31,684 children in our cohort, 11.9% had CCC. Children with CCC were more likely to receive intensive investigations and therapies, were less likely to receive aminopenicillins or third generation cephalosporins and were more likely to receive antibiotics against methicillin-resistant Staphylococcus aureus, Pseudomonas aeruginosa and anaerobes. Compared with children without these conditions, children with CCC had significantly increased length of stay [relative risk 1.43, 95% confidence interval (CI) 1.39-1.48] and hospital costs (relative risk 1.38, 95% CI 1.33-1.43), with increased odds of antibiotic escalation (odds ratio 1.51, 95% CI 1.35-1.70), pneumonia complications (odds ratio 1.47, 95% CI 1.24-1.75) and readmission (odds ratio 4.0, 95% CI 3.2-5.0).

DISCUSSION

Children with CCC comprise a significant proportion of children hospitalized for pneumonia and are at substantially increased risk of adverse outcomes. They have high rates of treatment with broad spectrum antibiotics, both at the time of hospitalization and subsequently. Research is needed to inform decision-making and guideline development, with goals of reducing adverse outcomes and unnecessary variation in management among children with CCC.

Treatment of mycoplasma pneumonia: a systematic review

BACKGROUND AND OBJECTIVE

Children with community-acquired lower respiratory tract infection (CA-LRTI) commonly receive antibiotics for Mycoplasma pneumoniae. The objective was to evaluate the effect of treating M. pneumoniae in children with CA-LRTI.

METHODS

PubMed, Cochrane Central Register of Controlled Trials, and bibliography review. A search was conducted by using Medical Subject Headings terms related to CA-LRTI and M. pneumoniae and was not restricted by language. Eligible studies included randomized controlled trials (RCTs) and observational studies of children #17 years old with confirmed M. pneumoniae and a diagnosis of CA-LRTI; each must have also compared treatment regimens with and without spectrum of activity against M. pneumoniae. Data extraction and quality assessment were completed independently by multiple reviewers before arriving at a consensus. Data were pooled using a random effects model.

RESULTS

Sixteen articles detailing 17 studies were included. The most commonly selected primary outcome was symptomatic improvement. Nine studies examined M. pneumoniae treatment in CA-LRTI secondary to M. pneumoniae, and 5 RCTs met criteria for meta-analysis. The suggested pooled risk difference of 0.12 (95% confidence interval, 20.04 to 0.20) favoring treatment was not significantly different and demonstrated significant heterogeneity. Limitations included substantial bias and subjective outcomes within the individual studies, difficulty interpreting testing modalities, and the inability to correct for mixed infections or timing of intervention.

CONCLUSIONS

We identified insufficient evidence to support or refute treatment of M. pneumoniae in CA-LRTI. These data highlight the need for well-designed, prospective RCTs assessing the effect of treating M. pneumoniae in CA-LRTI.

Treatment trends and outcomes in US hospital stays of children with empyema

BACKGROUND

Recently published practice guidelines continue to reflect uncertainty about the comparative effectiveness of various treatments for empyema in children. We describe treatment trends and outcomes in pediatric empyema using the most current nationally representative data.

METHODS

Using survey methods and Kids' Inpatient Databases from 1997 to 2009, we evaluated hospital stays in children 0-18 years of age. We used 2009 data to compare transfer-out rates and lengths of stay across various types of treatment, after adjusting for patient and hospital factors.

RESULTS

From 1997 to 2009, empyema discharges steadily increased from 3.1 to 6.0 per 100,000 children (P < 0.001 for trend) and also were increasingly likely (P < 0.01) to be coded for: (1) at least 1 pleural drainage procedure (76.4-83.2%), (2) multiple drainage procedures (36.0-41.6%) and (3) home health care (8.7-15.0%). By 2009, video-assisted thoracoscopic surgery was more commonly coded than chest tube drainage and was associated with a lower transfer-out rate (0.6% vs. 10.1%, adjusted P < 0.001) but no reduction in mean length of stay [11.2 vs. 13.4 days, adjusted incidence rate ratio 0.95 (95% confidence interval: 0.88-1.04)] for children neither admitted nor discharged by transfer.

CONCLUSIONS

US hospital stays for empyema in children not only continued to increase through 2009 but were also characterized by more intense procedural management. Outcomes results in this population-based study are consistent with practice guidelines and recommendations that recently endorsed chest tube drainage as an acceptable first treatment option for most children with empyema.

Factors associated with high resource utilization in pediatric skin and soft tissue infection hospitalizations

OBJECTIVE

To describe factors associated with prolonged lengths of stay (LOS) and increased charges for pediatric skin and soft tissue infection (SSTI) hospitalizations.

METHODS

This study was a cross-sectional analysis of pediatric SSTI hospital discharges in 2009 within the Healthcare Cost and Utilization Project Kids' Inpatient Database. Outcomes were prolonged LOS (>75th percentile) and increased hospital charges (>75th percentile). Multivariate logistic regression controlling for patient and hospital level factors was conducted for 2009 data to assess associations among variables.

RESULTS

The 75th percentile for LOS was 3 days. Infants had higher odds of prolonged LOS than other age groups (<1 year: 1; 1-4 years: 0.70 [95% confidence interval (CI): 0.64-0.76]; 5-12 years: 0.69 [95% CI: 0.63-0.76]; 13-18 years: 1.01 [95% CI: 0.91-1.10]), as did all minority groups compared with white subjects (black subjects: 1.23 [95% CI: 1.09-1.38]; Hispanic subjects: 1.33 [95% CI: 1.20-1.47]; and other races: 1.30 [95% CI: 1.12-1.50]). Public payers compared with private payers (odds ratio: 1.17 [95% CI: 1.10-1.26]) also had increased odds of prolonged LOS. The 75th percentile for charges was $14 317. The adolescent-aged category had higher odds of charges >75th percentile compared with the age category <1 year (odds ratio: 1.54 [95% CI: 1.36-1.74]). All racial/ethnic minorities had higher odds of charges >75th percentile compared with white subjects (black subjects: 1.38 [95% CI: 1.17-1.62]; Hispanic subjects: 1.90 [95% CI: 1.59-2.26]; and other races: 1.26 [95% CI: 1.06-1.50]).

CONCLUSIONS

Vulnerable populations, including infants, racial/ethnic minorities, and publicly insured children, had higher odds of increased resource utilization during hospitalizations for SSTIs. The findings of this study provide potential targets for future preventive and public health interventions.
