Abstract

OBJECTIVES: To describe variation in empirical antibiotic selection in infants <60 days old who are hospitalized with skin and soft-tissue infections (SSTIs) and to determine associations with outcomes, including length of stay (LOS), 30-day returns (emergency department revisit or readmission), and standardized cost.

METHODS: Using the Pediatric Health Information System, we conducted a retrospective study of infants hospitalized with SSTI from 2009 to 2014. We analyzed empirical antibiotic selection in the first 2 days of hospitalization and categorized antibiotics as those typically administered for (1) staphylococcal infection, (2) neonatal sepsis, or (3) combination therapy (staphylococcal infection and neonatal sepsis). We examined the association of antibiotic selection and outcomes using generalized linear mixed-effects models.

RESULTS: A total of 1319 infants across 36 hospitals were included; the median age was 30 days (interquartile range [IQR]: 17–42 days). We observed substantial variation in empirical antibiotic choice, with 134 unique combinations observed before categorization. The most frequently used antibiotics included staphylococcal therapy (50.0% [IQR: 39.2–58.1]) and combination therapy (45.4% [IQR: 36.0–56.0]). Returns occurred in 9.2% of infants. Compared with administration of staphylococcal antibiotics, use of combination therapy was associated with increased LOS (adjusted rate ratio: 1.35; 95% confidence interval: 1.17–1.53) and cost (adjusted rate ratio: 1.39; 95% confidence interval: 1.21–1.58), but not with 30-day returns.

CONCLUSIONS: Infants who are hospitalized with SSTI experience wide variation in empirical antibiotic selection. Combination therapy was associated with increased LOS and cost, with no difference in returns. Our findings reveal the need to identify treatment strategies that can be used to optimize resource use for infants with SSTI.

Within the United States, skin and soft-tissue infections (SSTIs) are responsible for nearly 60 000 pediatric admissions annually, with estimated aggregate annual charges of 840 million dollars.1 Hospitalizations for SSTI have become more frequent, with previous research revealing that infancy is independently associated with longer hospital length of stay (LOS) and increased cost.2,3 Among infants <60 days of age, clinical practice varies greatly in the evaluation of SSTIs.4,5 This variation may reflect health care provider concern for a possible increased risk of concomitant invasive bacterial infections (IBIs) because of the immaturity of the infant immune system.6 Variation in patient evaluation likely extends beyond diagnostic testing practices to include the decision of which antibiotics to empirically administer, specifically the decision to administer narrow-spectrum (ie, SSTI-directed) antibiotics or broad-spectrum antibiotics. Such variation is important to assess because broad-spectrum antibiotic use is associated with the development of antimicrobial resistance, Clostridium difficile infection, and adverse drug reactions.7 Early postnatal antibiotic use can influence the developing neonatal intestinal microbiome8–10 and may lead to lifelong consequences, including increased BMI, increased rates of diarrhea in early childhood, and an increased risk of developing allergies.11–13

In an effort to help standardize care, the Infectious Diseases Society of America published guidelines on the management of SSTIs and methicillin-resistant Staphylococcus aureus infections.14,15 However, these guidelines largely rely on data derived from studies of older children and adults to inform a consensus statement of antimicrobial management for SSTI. The neonatal literature used to inform these recommendations was largely based on a retrospective chart review from a single institution.16 Consequently, the extent to which these guidelines can be generalized to all infants with SSTI is unclear. Identifying patterns of antibiotic selection and the associated health outcomes across a larger, more diverse cohort of infants may help clinicians to make better empirical antibiotic choices and optimize resource use for infants with SSTI. Thus, our aims for this study are to describe empirical antibiotic selection in infants with SSTI and investigate the association of different empirical antibiotic regimens with LOS, readmission rates, and cost.

Methods

Study Design and Data Source

We conducted a multicenter, retrospective cohort study of infants <60 days of age with a diagnosis of SSTI. We extracted data from the Pediatric Health Information System (PHIS), an administrative database of 45 free-standing pediatric hospitals in the United States that are affiliated with the Children’s Hospital Association (Lenexa, KS). Patient data are deidentified within PHIS; however, encryption of patient identifiers allows for tracking of individual patients across visits. The current study included data from a total of 36 hospitals, with 9 hospitals excluded for lack of emergency department (ED) data or low hospital volumes (<10 cases). This study was reviewed and approved by the local institutional review board.

Study Population

Inclusion Criteria

Infants <60 days of age hospitalized (inpatient or observation status) at a PHIS-participating site from January 1, 2009, to December 31, 2014, were eligible for inclusion. International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes were used to identify infants with SSTI within the PHIS database. Infants were considered for inclusion on the basis of the presence of an ICD-9-CM principal diagnosis for an SSTI, including cellulitis, abscess, carbuncle, furuncle, or mastitis (Supplemental Table 4).2–5,17,18 If an infant had multiple hospitalizations within a 30-day period, only the first hospitalization was considered an index admission; subsequent ED revisits or hospitalizations were considered returns and were defined as same-, related-, or all-cause returns.

Exclusion Criteria

To identify infants with SSTI who were otherwise healthy, we excluded infants with primary immunodeficiency, HIV, malignancy, and complex chronic conditions.19 Infants with dacryocystitis, impetigo, pustulosis, lymphadenitis, omphalitis, perirectal abscess, fistula, and orbital cellulitis were also excluded (Supplemental Table 4) because of the potential that these infections could be managed differently and/or could require more expanded antibiotic coverage on the basis of the likely pathogen.14,20–25 Finally, infants were excluded if they did not receive systemic antibiotic therapy (oral or parenteral) within the first 2 days of hospitalization or if they received very broad-spectrum antibiotics (eg, cefepime or piperacillin and tazobactam) secondary to the possibility of coding misclassification and/or the treatment of conditions beyond SSTI or neonatal fever.

Antibiotic Classification

Empirical antibiotic selection was defined as antibiotics administered during the first 2 days of hospitalization. Because billing code data in the PHIS do not distinguish between administration in the ED or inpatient setting, our definition inherently included antibiotics given in the ED. This definition was chosen to capture the window of time when microbiologic test results are not available to guide the decision for antibiotic choice. Empirical antibiotic selection was divided into 2 broad categories: parenteral antibiotics and oral antibiotics (Supplemental Table 5). Parenteral antibiotics were further subdivided into antibiotics typically administered for staphylococcal infection, antibiotics typically administered for neonatal sepsis, and combination therapy (staphylococcal infection and neonatal sepsis). Antibiotics typically administered for staphylococcal infection included ampicillin-sulbactam, cefazolin, clindamycin, oxacillin, nafcillin, and vancomycin. Because the PHIS does not contain data on local susceptibilities, we chose to include agents with activity against methicillin-susceptible S aureus and/or methicillin-resistant S aureus with the assumption that providers would choose an agent on the basis of their local patterns of resistance. Antibiotics typically administered for neonatal sepsis included ampicillin and gentamicin, ampicillin and a third- or fourth-generation cephalosporin, or a third- or fourth-generation cephalosporin alone. Combination therapy was defined as concomitant use of neonatal sepsis antibiotics and staphylococcal antibiotic(s). The oral antibiotic category was defined as use of oral preparations alone during the first 2 days of hospitalization. Categorization was reviewed and confirmed by 1 of the board-certified pediatric infectious diseases physicians in the study group (R.J.M).

Outcome Measures

Outcome measures included hospital LOS (in days), returns (ED revisits and/or hospital readmission) within 30 days, and cost. The time frame of 30 days was chosen to measure subsequent visits associated with treatment failure, antibiotic-associated adverse effects, or IBI. Return visits were further classified as same cause, related cause, and/or all cause (Supplemental Table 6). A same-cause return was defined as a return for any of the diagnoses in our case identification strategy. A related-cause return was defined a priori and by group consensus as a return for reasons that could reasonably be attributed to management of an SSTI (eg, bacteremia, fever, and diarrhea). All-cause returns were defined as returns for any reason. Cost of index hospitalization included use from the ED visit and hospitalization. Costs are presented as standardized costs by using methodology previously described by Keren et al.26

Demographics and Covariates

Demographic characteristics included age, sex, race and/or ethnicity, primary payer, and region of the United States. All records were assessed for billing codes for fever,27 site of infection, IBI, incision and drainage procedures, obtainment of cultures (blood, cerebrospinal fluid [CSF], and wound), ICU services, and peripherally inserted central catheter (PICC) placement. IBI was defined as bacteremia and/or sepsis, meningitis, osteomyelitis, and pyogenic arthritis and was identified through ICD-9-CM codes (Supplemental Table 4). Additionally, we examined case mix index (CMI), which is a relative weight assigned to each discharge on the basis of All-Patient Refined Diagnosis Group (APR-DRG) assignment and ARP-DRG severity of illness. The weights are derived by Truven Health Analytics (Ann Arbor, MI) as the ratio of the average charge for discharges within a specific APR-DRG and severity of illness combination to the average charge for all discharges in the database. For simplicity of reporting, we split the weights at the median and combined the middle 2 quartiles into a single group to produce 3 categories: minor, moderate and/or major, and extreme.

Validation

An internal validation study was performed through chart review at 2 PHIS hospitals to assess the accuracy of our case identification strategy. Of the 131 medical records reviewed, our case identification strategy was associated with a positive predictive value of 90.8% (N = 119) for identifying included SSTI diagnoses. Two infants (1.5%) with billing codes for cellulitis had documentation to support a diagnosis of neonatal fever, and 10 infants (7.6%) with billing codes for cellulitis had documentation to support a diagnosis of perirectal abscess. Of the 131 charts reviewed, fever (temperature ≥38°C reported or documented) was identified for 18 infants (13.7%). However, fever was coded for only 9 infants (6.9%) in the PHIS. On chart review of these 9 infants, 4 had a documented fever at ≥38°C, 1 had a temperature of 37.9°C, 1 had a subjective fever reported, and 3 infants did not have documentation to support fever. On chart review, 6 infants (4.6%) had positive results on blood cultures, all of which were considered to be contaminants by the medical team (4 coagulase-negative staphylococci, 1 Streptococcus parasanguinis, and 1 Bacillus species [not anthracis]). No cases of meningitis, osteomyelitis, or pyogenic arthritis were identified.

Statistical Analysis

We calculated summary statistics for continuous variables with medians and interquartile ranges (IQRs), and categorical variables were summarized with frequencies and percentages. We made comparisons between infants who did and did not have a return using the χ2 test for categorical measures or the Kruskal-Wallis test for continuous measures. We examined the association between antibiotic groups (eg, staphylococcal and combination therapy) and outcomes using generalized linear mixed-effects models with a random intercept for each hospital. We performed age-stratified, diagnosis-stratified, and overall analyses. For diagnosis-stratified analyses, adjustments were made for age, sex, hospital, census region, CMI, incision and drainage, fever code, culture obtainment (blood, CSF, and wound), and ICU use. For age-stratified and overall analyses, we additionally adjusted for infection type. For the outcomes of LOS and cost, we used an exponential distribution, and we present the results as rate ratios with 95% confidence intervals (CIs). For all other outcomes, we used a binomial distribution, and we present the results as odds ratios with 95% CIs. Finally, we performed a sensitivity analysis, removing children with CSF cultures to isolate infants who did not have a complete evaluation for serious bacterial infection on the basis of their initial presentation. All statistical analyses were performed by using SAS 9.4 (SAS Institute, Inc, Cary, NC), and P values <.05 were considered statistically significant.

Results

Patient Characteristics

Within the study period, 1319 infants met inclusion criteria (Fig 1). The median age of infants was 30 days (IQR: 17–42 days). The majority of infants were non-Hispanic white, had government insurance, and were located in the southern United States (Table 1). A total of 790 (59.9%) infants were hospitalized with a diagnosis code for cellulitis and abscess, 4 (0.3%) for carbuncle and furuncle, and 525 (39.8%) for mastitis. Incision and drainage were documented in 234 (17.7%) infants. Overall, 1063 (80.6%) infants had a blood culture obtained alone or in combination with a CSF culture, 408 (30.9%) had a CSF culture obtained, and 834 (63.2%) had a wound culture obtained. A fever code was documented for 59 (4.5%) infants, and an IBI was coded for 24 (1.8%) infants. We observed increased obtainment of CSF cultures among infants who received neonatal (60.0%) or combination therapy (49.0%) compared with infants who received staphylococcal (11.7%) or oral antibiotics (0%; Supplemental Table 7). Additionally, we observed increased use of neonatal or combination therapy among infants 0 to 28 days and among infants with a documented fever code.

Cohort Demographics and Clinical Characteristics

Variation in Empirical Antibiotic Selection

We observed wide variation in empirical antibiotic choice across hospitals (Fig 2). Before categorization, there were 134 unique combinations of antibiotics used in the first 2 days of hospitalization. The most frequently used antibiotic regimens included staphylococcal antibiotics (50.0% [IQR: 39.2–58.1]) and combination therapy (45.4% [IQR: 36.0–56.0]). Clindamycin was the most commonly used staphylococcal antibiotic (1057 infants; 80.1% of the entire cohort). Among all infants included in our cohort, 282 (21.4%) received vancomycin.

Association of Antibiotic Selection and Outcomes

In unadjusted analyses, there were significant differences in LOS (2.7 vs 1.9 days; P < .001) and standardized cost of the index encounter ($5518 vs $3726; P < .001) among infants who received combination therapy versus infants who received staphylococcal antibiotics (Table 2). After adjustment, infants who received combination therapy had an average LOS that was 35% longer than that of infants who received staphylococcal antibiotics (adjusted rate ratio [aRR]: 1.35 [95% CI: 1.17–1.53]; P < .001). Standardized costs of the index encounter were nearly 40% higher among infants who received combination therapy versus infants who received staphylococcal antibiotics (aRR: 1.39 [95% CI: 1.21–1.58]; P < .001). These findings remained similar in age-stratified, diagnosis-stratified, and sensitivity analyses (Tables 2 and 3, Supplemental Table 8). In particular, in sensitivity analyses in which infants with CSF cultures were excluded, infants who received combination therapy had an average LOS that was 37% greater and standardized costs that were 47% higher than those of infants who received staphylococcal antibiotics.

Unadjusted and Adjusted Outcomes (LOS, Standardized Cost of Index Hospitalization, and 30-d Returns) Stratified by Diagnosis

Before adjustment, 30-day related-cause returns were observed in 2.8% (95% CI: 2.0–3.8) of infants, whereas same-cause returns were observed in 2.6% (95% CI: 1.8–3.6) of infants (Table 2). In both unadjusted and adjusted analyses, there were no significant differences in all-, related-, or same-cause return rates among infants who received combination therapy versus infants who received staphylococcal antibiotics. Similarly, no significant differences were observed in age-stratified or diagnosis-stratified analyses (Tables 2 and 3).

Discussion

In this multicenter study, we observed considerable variation in the choice of the empirical antibiotic selected to manage SSTI in infants <60 days old who were hospitalized. Despite wide variation in antibiotics, the vast majority of infants received an antibiotic within 1 of 2 broad categories (staphylococcal antibiotics or combination therapy). Those infants who received combination therapy had a longer LOS and higher costs compared with those who received staphylococcal antibiotics. Despite observing longer LOS among infants who received combination therapy versus staphylococcal coverage, we did not observe lower rates of 30-day returns (ED revisits and/or readmission). With our findings, we suggest that there may be opportunities to reduce broad-spectrum antibiotic use in infants with SSTI without adversely affecting clinical outcomes.

With our current study, we build on previous single- and regional-center investigations by demonstrating significant variation in empirical antibiotic selection for infants with SSTI within and across geographically diverse institutions. Variation in empirical antibiotic exposure is important to recognize, considering the large proportion of infants who received potentially unnecessary broad-spectrum coverage in our study and the growing body of research in which possible negative consequences from early postnatal broad-spectrum antibiotic exposure are suggested.8–13 Consistent with previous research of young infants with SSTI,4,5,28 the prevalence of IBI in our study was 1.8%; as such, with our findings, we suggest that for a majority of infants with SSTI, there may be an opportunity to safely reduce broad-spectrum antimicrobial use. However, future research is needed to develop risk stratification tools to determine which infants are at a higher risk for the development of IBI, allowing for a more targeted approach to invasive testing and broad-spectrum antimicrobial use.

Oral agents were rarely used as empirical therapy among our cohort of infants who were hospitalized. This finding may partly reflect the lack of strong evidence for empirical oral therapy in infants, concern for antibiotic absorption and relative lack of pharmacokinetic data for the youngest patients, the perceived severity of infection, clinician concern for IBI, failure of outpatient treatment, or physician perception of the need for parenteral therapy for patients who are hospitalized. Additionally, although the vast majority of SSTI infections occur secondary to staphylococcal or streptococcal organisms,14 a total of 51% of infants within our study group were exposed to broad-spectrum antibiotics, which provide enhanced Gram-negative coverage but no added benefit for treatment of the most commonly identified organisms responsible for SSTI (Gram-positive organisms). Although some of the infants who received broad-spectrum antibiotics may have been febrile or appeared ill, our observation of longer LOS and higher costs among infants receiving combination therapy persisted even after controlling for fever, CMI, or obtainment of a CSF culture. Taken together, our findings reveal the need to evaluate the efficacy and safety of oral and narrow-spectrum antibiotic therapy for treatment of SSTI in young infants.

Infants who received combination therapy in our current study were younger and more frequently had codes for fever and CSF testing. Infants receiving combination therapy had LOSs and costs that were 35% to 40% higher than those of infants who received staphylococcal coverage alone. Our findings may in part reflect physician decision to delay discharge while awaiting culture results and may further reveal the need for diagnostic testing and antimicrobial stewardship interventions that balance the benefits of broadly evaluating and treating the few infants with concomitant IBI with the risks of performing potentially unnecessary tests and treating many infants with unnecessarily broad antibiotic therapy.29 Future efforts to address potential reductions of LOS in this population will be important because hospitalization can be associated with the risk of acquiring nosocomial infections, increased psychosocial burden on families, and reduced quality of life for the child who is hospitalized.30–33

There are limitations to our study. First, we used an administrative database to obtain our data; consequently, some of the variation we observed may reflect differences in administrative billing and coding practices. For example, fever was not reliably coded in our study, and compared with other similar investigations, assignment of ICD-9-CM codes for fever was low.5 Lack of reliable fever coding limits our ability to examine the impact of fever on antibiotic prescribing and limits our ability to make any recommendations regarding the appropriate treatment of SSTI in the setting of fever. The use of an administrative data set also limits our ability to evaluate the association of patient presentation with clinical decision-making. For example, lack of codes for CSF testing does not exclude the possibility that a lumbar puncture was indicated but unsuccessful or not attempted. We had a limited ability to assess the severity of SSTI (including bedside drainage procedures) and local patterns of resistance or to examine microbiologic data, which are factors that might have influenced empirical antimicrobial selection. However, our focus on empirical antibiotic therapy would be expected to minimize the influence of microbiologic test results on antibiotic choices. Finally, because our study population was composed solely of infants who were hospitalized at children’s hospitals, our results may not be generalizable to infants in other settings.

Conclusions

Infants hospitalized with SSTI experience wide variation in empirical antimicrobial selection. Compared with staphylococcal antibiotics alone, use of combined therapy was associated with increased LOS and cost (without increased rates of ED revisits and/or readmissions). Given the low rate of IBI in infants with SSTI, we suggest with our findings that there may be an opportunity to safely reduce broad-spectrum antimicrobial use in infants with SSTI.
