Characteristics of patients treated for orbital cellulitis: An analysis of inpatient data

Subperiosteal abscess volume; an objective indication for surgical management in pediatrics

PURPOSE

Subperiosteal abscess (SPA) can lead to devastating morbidity and mortality. Prompt management is important; however, the choice of management route is controversial. This study investigates factors associated with surgical management and defines a cut-off abscess volume prompting surgical intervention.

METHODS

SPA cases presented to King Saud University Medical City (KSUMC) from 2014 to 2023 were reviewed. The surgical approach was studied in association with factors including age, gender, symptoms and signs, laboratory results, computed tomography (CT) characteristics, medications, and surgical approach. Multiple statistical tests were used for analysis, including student t-test, chi-square, multiple logistic regression analysis, and receiver operating characteristic (ROC) analysis.

RESULTS

Patients were managed medically (n = 14, 45.16%) or surgically (n = 17, 54.84%). The average duration of antibiotics was 15 days. Superior SPA favors surgical management (OR = 6.722, CI [1.332-33.913], p = 0.029), along with the use of steroids (OR = 5.625, CI [0.915-34.572], p = 0.049), and abscess volume (OR = 10.003, CI [1.418-70.540], p < 0.001). However, the only factor attributing to a surgical decision on multivariate logistic regression analysis was abscess volume (OR = 5.126, CI [1.023-25.694], p = 0.047). SPA volume of ≥ 0.648 ml strongly prompts surgical management, with a sensitivity of 94.1% and a specificity of 71.4% (p = 0.000).

CONCLUSION

SPA volume increases the likelihood of surgical intervention by five times, especially when abscess volume is ≥ 0.648 ml.

Microbial patterns and culture utility in orbital cellulitis

PURPOSE

To determine the prevalence and types of pathogens found in children with orbital cellulitis and to evaluate the utility of nonoperative cultures.

METHODS

This was a retrospective cohort study of children with imaging-confirmed orbital cellulitis over a period of 8 years. Outcomes included prevalence and types of organisms, polymicrobial infection, mixed aerobic-anaerobic infection, effect of age, and culture utility.

RESULTS

Of 220 children with orbital cellulitis, 112 (51%) had cultures taken; 69 (31%) had surgical intervention. Culture sources for the 112 children with cultures included blood (57 patients [51%]), sinus (53 [47%]), orbit (42 [38%]), brain (6 [5%]), and skin/conjunctiva/lacrimal sac (6 [5%]). Streptococcus anginosus group strains grew in cultures from 19 children (17%); methicillin-sensitive Staphylococcus aureus (MSSA), in 15 (13%); Streptococcus pyogenes, in 12 (11%); methicillin-resistant Staphylococcus aureus (MRSA), in 6 (5%); anaerobic/facultative gram negative rods, in 8 (7%); anaerobic Gram-positive cocci, other Viridans group streptococci, and Streptococci pneumoniae, in 3 (3%) each; and normal respiratory/skin flora, in 23 (21%). Polymicrobial infection (P = 0.08) and anaerobic organisms (P = 0.58) did not differ by age (range, 0.1-16.8 years). In all 220 (100%) children, nonoperative cultures were either not obtained (108 [49%]), not helpful in avoiding surgery (69 [31%]), showed no growth (39 [18%]), or grew an organism that did not change management from empiric therapy (4 [2%]).

CONCLUSIONS

While many organisms may be cultured from children with orbital cellulitis, Streptococcus and MSSA were the most common in our study cohort. MRSA is uncommon, so initial empiric coverage is not necessary. Rates of polymicrobial and anaerobic infection were similar across ages. Our results indicate that nonoperative cultures are not indicated in the initial medical management of orbital cellulitis; in our cohort, they neither resulted in treatment changes nor helped avoid surgery.

Differences in characteristics, aetiologies, isolated pathogens, and the efficacy of antibiotics in adult patients with preseptal cellulitis and orbital cellulitis between 2000-2009 and 2010-2019

BACKGROUND/AIMS

To understand whether the epidemiology, aetiologies, common pathogens and the antibiotic efficacy against the identified bacteria of periorbital cellulitis in adults have changed recently (2010-2019) compared with the past decade (2000-2009).

METHODS

Adult patients (n=224) diagnosed with preseptal cellulitis and orbital cellulitis admitted to Kaohsiung Veterans General Hospital during 2000-2019 were retrospectively reviewed. Demographic and clinical characteristics, isolated pathogens and antibiotic susceptibility tests against the commonly cultured bacteria were analysed.

RESULTS

Preseptal cellulitis showed a tendency of female predominance. Patients in their 60s showed an incidence peak; more cases were observed during winter. The most common predisposing factor was dacryocystitis (15.5%-30.5%), followed by hordeolum (15.5%-24.8%). Aetiology of sinusitis (p=0.001) decreased and that of conjunctivitis (p=0.007) increased significantly with time. Culture results of nasopharyngeal swabs and local abscess showed higher positivity rate than conjunctival swab. The most common isolates were methicillin-susceptible Staphylococcus aureus, methicillin-resistant S. aureus, coagulase-negative staphylococci and Pseudomonas aeruginosa. Antibiotics including fluoroquinolones and vancomycin were effective; in contrast, ampicillin/sulbactam and oxacillin showed decreasing efficacy against gram-positive bacteria. For antibiotic treatment against P. aeruginosa, fluoroquinolones, ceftazidime, piperacillin and imipenem were ideal choices.

CONCLUSION

In isolated pathogens, the increasing trend of methicillin-resistant S. aureus detection was compatible with reducing oxacillin efficacy against periorbital infection. In our study, the report of antibiotic efficacy against the most common identified bacteria offered empirical choices for hospitalised patients with periorbital infection before obtaining culture results.

High risk and low prevalence diseases: Orbital cellulitis

INTRODUCTION

Orbital cellulitis is an uncommon but serious condition that carries with it a potential for significant morbidity.

OBJECTIVE

This review highlights the pearls and pitfalls of orbital cellulitis, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence.

DISCUSSION

Orbital cellulitis refers to infection of the globe and surrounding soft tissues posterior to the orbital septum. Orbital cellulitis is typically caused by local spread from sinusitis but can also be caused by local trauma or dental infection. It is more common in pediatric patients compared to adults. Emergency clinicians should first assess for and manage other critical, sight-threatening complications such as orbital compartment syndrome (OCS). Following this assessment, a focused eye examination is necessary. Though orbital cellulitis is primarily a clinical diagnosis, computed tomography (CT) of the brain and orbits with and without contrast is critical for evaluation of complications such as abscess or intracranial extension. Magnetic resonance imaging (MRI) of the brain and orbits with and without contrast should be performed in cases of suspected orbital cellulitis in which CT is non-diagnostic. While point-of-care ultrasound (POCUS) may be useful in differentiating preseptal from orbital cellulitis, it cannot exclude intracranial extension of infection. Management includes early administration of broad-spectrum antibiotics and ophthalmology consultation. The use of steroids is controversial. In cases of intracranial extension of infection (e.g., cavernous sinus thrombosis, abscess, or meningitis), neurosurgery should be consulted.

CONCLUSION

An understanding of orbital cellulitis can assist emergency clinicians in diagnosing and managing this sight-threatening infectious process.

Factors Associated with Surgery and Imaging Characteristics in Severe Orbital Infections

OBJECTIVES

To evaluate risk factors associated with surgical intervention and subperiosteal/orbital abscess in hospitalized children with severe orbital infections.

STUDY DESIGN

We conducted a multicenter cohort study of children 2 months to 18 years hospitalized with periorbital or orbital cellulitis from 2009 to 2018 at 10 hospitals in Canada. Clinical details were extracted, and patients were categorized as undergoing surgical or medical-only management. Primary outcome was surgical intervention and the main secondary outcome was clinically important imaging. Logistic regression was used to identify predictors.

RESULTS

Of 1579 patients entered, median age was 5.4 years, 409 (25.9%) had an orbital/subperiosteal abscess, and 189 (12.0%) underwent surgery. In the adjusted analysis, the risk of surgical intervention was associated with older age (age 9 to <14: aOR 3.9, 95% CI 2.3-6.6; and age 14 to ≤18 years: aOR 7.0, 95% CI 3.4-14.1), elevated C-reactive protein >120 mg/L (aOR 2.8, 95% CI 1.3-5.9), elevated white blood cell count of 12-20 000/μL (aOR 1.7, 95% CI 1.1-2.6), proptosis (aOR 2.6, 95% CI 1.7-4.0), and subperiosteal/orbital abscess (aOR 5.3, 95% CI 3.6-7.9). There was no association with antibiotic use before hospital admission, sex, presence of a chronic disease, temperature greater than 38.0°C, and eye swollen shut. Complications were identified in 4.7% of patients, including vision loss (0.6%), intracranial extension (1.6%), and meningitis (0.8%).

CONCLUSIONS

In children hospitalized with severe orbital infections, older age, elevated C-reactive protein, elevated white blood cell count, proptosis, and subperiosteal/orbital abscess were predictors of surgical intervention.

Epidemiology and Management of Orbital Cellulitis in Children

BACKGROUND

The epidemiology of orbital cellulitis likely has evolved due to the emergence of methicillin-resistant Staphylococcus aureus (MRSA) and the adoption of pneumococcal conjugate vaccination. In the absence of published guidelines, management is highly variable. We characterized epidemiology and management over an 11-year period.

METHODS

A retrospective cohort study of children 0 to 21 years of age with orbital cellulitis +/- subperiosteal orbital abscess hospitalized at a large quaternary children's hospital from January 2008 to June 2018. We reviewed charts for demographic characteristics, clinical features, management, and outcomes. Using multivariable logistic regression, we evaluated predictors of surgical intervention and assessed whether corticosteroid use or antibiotic duration was related to clinical outcomes.

RESULTS

Among 220 patients, methicillin-susceptible S. aureus was the most common organism (26.3%), with MRSA found in only 5.0%. Rates of vancomycin use fluctuated annually from 40.9% to 84.6%. Surgery was performed in 39.5% of the patients. Corticosteroids, used in 70 patients (32.1%), were unrelated to treatment failure (n = 9), defined as persistent signs and symptoms or initial clinical improvement followed by worsening (P = .137). The median antibiotic duration was 17 days (interquartile range 14-26). After controlling for age, gender, proptosis, eye pain with movement, eyelid swelling, neutrophil count, and corticosteroid use, treatment failure was not significantly associated with receipt of ≥ 3 weeks of antibiotic therapy (8/84, 9.5%) compared with > 2 but < 3 weeks (0/51, 0.0%) or ≤ 2 weeks (1/85, 1.2%) (adjusted odds ratio = 5.83 for ≥ 3 vs ≤2 weeks; 95% confidence interval: 0.58, 59.0).

CONCLUSIONS

Although MRSA was rare, empiric vancomycin use was high. Treatment failure was uncommon in patients who received ≤ 2 weeks of therapy, suggesting that shorter durations are adequate in some patients.

Association Between Corticosteroids and Outcomes in Children Hospitalized With Orbital Cellulitis

OBJECTIVES

To examine the association between systemic corticosteroid use and outcomes for children hospitalized with orbital cellulitis at US children's hospitals.

METHODS

We conducted a multicenter observational study using administrative data from the Pediatric Health Information System database from 2007 to 2019. Children between the ages of 2 months and 18 years with International Classification of Diseases, Ninth Revision, Clinical Modification or 10th Revision, Clinical Modification discharge diagnostic codes of orbital cellulitis were included. The primary exposure was receipt of systemic corticosteroids on the day of hospital admission. The primary outcome was hospital length of stay, and secondary outcomes included surgical intervention, ICU admissions, revisits, and health care costs. We used generalized logit model with inverse probability weighting logistic regression to adjust for demographic factors and assess for differences in clinical outcomes reported.

RESULTS

Of the 5832 patients hospitalized with orbital cellulitis, 330 (5.7%) were in the corticosteroid group and 5502 (94.3%) were in the noncorticosteroid group. Patients in the corticosteroid group were older, had more severe illness, and received broad spectrum antibiotics. In adjusted analyses, corticosteroid exposure was not associated with differences in length of hospital stay, need for surgical intervention, ICU admissions, emergency department revisits, 30-day hospital readmissions, or hospital costs. Restricting the analysis to only those patients who received broad spectrum antibiotics did not change the findings.

CONCLUSIONS

Early use of systemic corticosteroids in hospitalized children with orbital cellulitis is not associated with improved clinical outcomes. Use of corticosteroids in hospitalized children with orbital cellulitis should be discouraged outside of clinical trials.

Corticosteroids for Acute Orbital Cellulitis

OBJECTIVES

Standard treatment of children hospitalized for acute orbital cellulitis includes systemic antibiotics. Recent data from single-center studies suggest the addition of systemic corticosteroids may hasten clinical improvement and reduce hospital length of stay (LOS). We investigate the potential relationship between corticosteroid exposure and duration of hospitalization for pediatric orbital cellulitis.

METHODS

Using Pediatric Health Information System registry data from 51 children's facilities, we performed a retrospective cohort study of children hospitalized for orbital cellulitis <18 years of age from 2007 to 2018. The primary study outcome was hospital LOS. Secondary outcomes included frequency of surgical interventions, PICU admission, and 30-day related-cause readmission.

RESULTS

Of the 5645 children included for study, 1347 (24%) were prescribed corticosteroids within 2 days of admission. Corticosteroid prescription was not associated with LOS in analyses adjusted for age; presence of meningitis, abscess, or vision issues; and operative episode and PICU admission within 2 days (e ^β = 1.01, 95% confidence interval [CI]: 0.97-1.06). Corticosteroid exposure was associated with operative episodes after 2 days of hospitalization (odds ratio = 2.05, 95% CI: 1.29-3.27) and 30-day readmission (odds ratio = 2.40, 95% CI: 1.52-3.78) among patients with a primary diagnosis of orbital cellulitis.

CONCLUSIONS

In this database query, we were not able to detect a reduction in LOS associated with corticosteroid exposure during hospitalization for orbital cellulitis. Corticosteroid prescription was associated with PICU admission and operative episodes after 2 days of hospitalization. Before the adoption of routine corticosteroid use, prospective, randomized control trials are needed.

Changes in the Management of Severe Orbital Infections Over Seventeen Years

OBJECTIVES

Periorbital and orbital cellulitis are common but serious infections in children. Management of these infections varies because of an absence of clinical guidelines, but it is unclear if management within institutions has changed over time. We compared the management and outcomes of children hospitalized with periorbital and orbital cellulitis in 2 eras.

METHODS

Data were extracted from records of children hospitalized at a tertiary care children's hospital with periorbital or orbital cellulitis from 2000 to 2005 and 2012 to 2016. Patient demographics, cross-sectional imaging, antibiotic and corticosteroid use, length of stay, and surgical rates were collected. Data from the eras were compared by using descriptive statistics, t tests, Mann-Whitney U tests, Fisher's exact tests, and χ² tests.

RESULTS

There were 318 children included, 143 from 2000 to 2005 and 175 from 2012 to 2016. Compared with the first era, in the second era there were increased rates of MRI (5% vs 11%, P = .04), although rates of computed tomography scan use remained unchanged (60% vs 65%); increased number (1 vs 3, P < .01) and spectrum of antibiotics; increased use of intranasal corticosteroids (3% vs 49%, P < .01); and subspecialty consultation (89% vs 99%, P = .01). There were no differences in length of stay, readmission, or surgical rates between eras.

CONCLUSIONS

There has been considerable change in the management of hospitalized children with severe orbital infections at our institution, including the rates of MRI, number and spectrum of antibiotics used, use of adjunctive agents, and increased subspecialty involvement with no observed impact on clinical outcomes. Future research is needed to rationalize antimicrobial therapy and reduce low-value health care.

Corticosteroids for periorbital and orbital cellulitis

BACKGROUND

Periorbital and orbital cellulitis are infections of the tissue anterior and posterior to the orbital septum, respectively, and can be difficult to differentiate clinically. Periorbital cellulitis can also progress to become orbital cellulitis. Orbital cellulitis has a relatively high incidence in children and adults, and potentially serious consequences including vision loss, meningitis, and death. Complications occur in part due to inflammatory swelling from the infection creating a compartment syndrome within the bony orbit, leading to elevated ocular pressure and compression of vasculature and the optic nerve. Corticosteroids are used in other infections to reduce this inflammation and edema, but they can lead to immune suppression and worsening infection.

OBJECTIVES

To assess the effectiveness and safety of adjunctive corticosteroids for periorbital and orbital cellulitis, and to assess their effectiveness and safety in children and in adults separately.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2020, Issue 3); Ovid MEDLINE; Embase.com; PubMed; Latin American and Caribbean Health Sciences Literature Database (LILACS); ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). We did not use any date or language restrictions in the electronic search for trials. We last searched the electronic databases on 2 March 2020.

SELECTION CRITERIA

We included studies of participants diagnosed with periorbital or orbital cellulitis. We excluded studies that focused exclusively on participants who were undergoing elective endoscopic surgery, including management of infections postsurgery as well as studies conducted solely on trauma patients. Randomized and quasi-randomized controlled trials were eligible for inclusion. Any study that administered corticosteroids was eligible regardless of type of steroid, route of administration, length of therapy, or timing of treatment. Comparators could include placebo, another corticosteroid, no treatment control, or another intervention.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures recommended by Cochrane.

MAIN RESULTS

The search yielded 7998 records, of which 13 were selected for full-text screening. We identified one trial for inclusion. No other eligible ongoing or completed trials were identified. The included study compared the use of corticosteroids in addition to antibiotics to the use of antibiotics alone for the treatment of orbital cellulitis. The study included a total of 21 participants aged 10 years and older, of which 14 participants were randomized to corticosteroids and antibiotics and 7 participants to antibiotics alone. Participants randomized to corticosteroids and antibiotics received adjunctive corticosteroids after initial antibiotic response (mean 5.13 days), at an initial dose of 1.5 mg/kg for three days followed by 1 mg/kg for another three days before being tapered over a one- to two-week period. We assessed the included study as having an unclear risk of bias for allocation concealment, masking (blinding), selective outcome reporting, and other sources of bias. Risk of bias from sequence generation and incomplete outcome data were low. The certainty of evidence for all outcomes was very low, downgraded for risk of bias (-1) and imprecision (-2). Length of hospital stay was compared between the group receiving antibiotics alone compared to the group receiving antibiotics and corticosteroids (mean difference (MD) 4.30, 95% confidence interval (CI) -0.48 to 9.08; 21 participants). There was no observed difference in duration of antibiotics between treatment groups (MD 3.00, 95% CI -0.48 to 6.48; 21 participants). Likewise, preservation of visual acuity at 12 weeks of follow-up between group was also assessed (RR 1.00, 95% CI 0.82 to 1.22; 21 participants). Pain scores were compared between groups on day 3 (MD -0.20, 95% CI -1.02 to 0.62; 22 eyes) along with the need for surgical intervention (RR 1.00, 95% CI 0.11 to 9.23; 21 participants). Exposure keratopathy was reported in five participants who received corticosteroids and antibiotics and three participants who received antibiotic alone (RR 1.20, 95% CI 0.40 to 3.63; 21 participants). No major complications of orbital cellulitis were seen in either the intervention or the control group. No side effects of corticosteroids were reported, although it is unclear which side effects were assessed.

AUTHORS' CONCLUSIONS

There is insufficient evidence to draw conclusions about the use of corticosteroids in the treatment of periorbital and orbital cellulitis. Since there is significant variation in how corticosteroids are used in clinical practice, additional high-quality evidence from randomized controlled trials is needed to inform decision making. Future studies should explore the effects of corticosteroids in children and adults separately, and evaluate different dosing and timing of corticosteroid therapy.

Paediatric periorbital cellulitis: A 10-year retrospective case series review

AIM

To identify the predictors of poor outcome and need for surgical management in paediatric patients with periorbital cellulitis. To assess the adherence to local guidelines in the management of periorbital cellulitis.

METHODS

Retrospective descriptive analysis of clinical, laboratory and radiological characteristics of 175 paediatric periorbital cellulitis presentations at a UK teaching hospital over a 10-year period. Regression investigated correlations for continuous and categorical variables.

RESULTS

A total of 175 paediatric presentations were diagnosed as periorbital infections over the 10-year period. Of these, 139 had pre-septal cellulitis, 27 had a subperiosteal abscess, 6 had an orbital cellulitis, 1 had an orbital abscess, 1 a cavernous sinus thrombosis and 1 an extradural abscess. Median age at presentation was 5 years (range: 1 month-17 years). In total, 169 (97%) cases received systemic antimicrobial treatment. Cross-sectional imaging occurred in 30% of cases and 18% required surgical intervention. Increasing C-reactive protein was associated with greater risk of post-septal disease and requiring surgery. The best predictors of post-septal disease in the multivariate analysis (R² = 0.49, P = ≤0.001) were ophthalmoplegia (P = 0.009), proptosis (P = 0.016) and pain on eye movement (P = 0.046). Proptosis was the single most significant predictor of surgical management (R² = 0.53, P = <0.001).

CONCLUSION

Multidisciplinary involvement and early medical management can improve outcomes for most patients. Those who deteriorate despite medical management should be considered for prompt imaging and surgical management to avoid serious life-threatening or sight-threatening complications.

Non-medial infectious orbital cellulitis: etiology, causative organisms, radiologic findings, management and complications

BACKGROUND

Orbital cellulitis is an ophthalmic emergency, which is associated with vision-threatening adverse effects. The purpose of this study is investigating etiology, radiologic findings, management and complications of patients with non-medial orbital cellulitis.

METHOD

A retrospective medical record and radiologic file review of patients with infectious orbital cellulitis was performed to detect all patients with non-medial orbital cellulitis who referred to Khalili hospital from 2016 to 2019. Age, sex, origin of infection, size of collection or abscess, medical or surgical management, microbiology, first and final best-corrected visual acuity, duration of admission, and complications was recorded. Patients divided into two groups; medical management and surgical management groups and all of data compared between in this groups.

RESULTS

Of ninety-six patients with infectious orbital cellulitis, 23 cases (14 male, 9 female) were included. Five patients (21.7%) were managed medically and 18 patients (78.3%) were managed surgically. Patients' age range was 5-70 years old. Most common location for non-medial cellulitis was superior space (66.7% in surgical and 40% in medical group; p = 0.511). In 13 cases of surgical group (72.3%) were detected microorganisms. The mean ± SD of collection volume in medical group were 476.5 ± 290.93 mm³ and 2572.94 ± 1075.75 mm³ in surgical group (p < 0.001). Ten patients in surgical group had compressive optic neuropathy. The mean ± SD of collection volume was 3204.97 ± 879.88 mm³ in patient with compressive optic neuropathy and 1280.43 ± 880.68 mm³ in patient without compressive optic neuropathy (P < 0.001). One case complicated by subdural empyema and another case progressed to necrotizing fasciitis.

CONCLUSION

Non-medial orbital cellulitis is an uncommon but sight-threatening and life-threatening condition. Timely diagnosis and accurate management reduce morbidity and mortality. Combined surgery for patients with superior or supra-temporal and large non-medial abscess is recommended.

Incidence and extent of sinus procedures in treatment of pediatric orbital cellulitis

INTRODUCTION

It is unknown the optimal extent of sinus surgery in pediatric patients with orbital cellulitis. Our aim was to determine the nationwide incidence of sinus procedures used to treat pediatric orbital cellulitis. Additionally, we sought to identify patient-factors that influence a multi-procedural approach.

METHODS

Cross-sectional analysis of 15,260 cases of primary pediatric orbital cellulitis identified in the Kids' Inpatient Database (KID) from January 1, 2003 to December 31, 2012. Cases were included if they contained a primary diagnosis code of orbital cellulitis. Frequency of sinus procedures in relation to pediatric age cohort were noted (≤8 years versus 9-20 years). Comorbidities, cost, and length-of-stay were compared between age cohorts. Multivariate models investigated patient-factors associated with multiple sinus procedures and patient-factors that affected hospital costs and length-of-stay.

RESULTS

Children ≤8 years of age constituted 67% of cases (n = 10,290). 1103 cases (7.2%) were treated with at least one defined sinus procedure; and, 712 of these cases documented more than one sinus procedure. The younger cohort (≤8 years) exhibited fewer sinus procedures and a lower rate of reoperation (4.6% vs 12.8%, p < .001; 5.1% vs 7.7%, p < .001, respectively). Presence of cellulitis/abscess of the face was the strongest predictor of multiple sinus procedures (OR = 1.982, p = .033). Patients with acute sinusitis and those >8 years had similarly increased odds of a multi-procedural approach (OR = 1.333, p = .049; OR = 1.367, p = .032, respectively). Multivariate analysis of cost and length-of-stay found that patients >8 years incurred 14% longer hospital stays and an increase in costs of 9% compared to younger patients (p = .001, p = .039; respectively). The secondary diagnosis with the largest effect on length-of-stay and cost was an intracranical abscess (OR = 2.352, p < .001; OR = 2.752, p < .001; respectively).

CONCLUSION

In a nationwide population of pediatric patients with primary orbital cellulitis there was an incidence of sinus surgery in 7.2% of cases - with patients over 8 years having a 2.8-fold increase compared to younger patients. Additionally, nearly two-thirds of patients treated with sinus surgery had multiple sinus procedures. The high incidence of multiple sinus procedures suggests that further prospective studies are needed to elucidate the extent of drainage associated with the best patient outcomes.

Care and outcomes of Canadian children hospitalised with periorbital and orbital cellulitis: protocol for a multicentre, retrospective cohort study

INTRODUCTION

Skin and soft tissue infections of the eye can be classified based on anatomic location as either anterior to the orbital septum (ie, periorbital cellulitis) or posterior to the orbital septum (ie, orbital cellulitis). These two conditions are often considered together in hospitalised children as clinical differentiation is difficult, especially in young children. Prior studies have identified variation in management of hospitalised children with orbital cellulitis; however, they have been limited either as single centre studies or by the use of administrative data which lacks clinical details important for interpreting variation in care. We aim to describe the care and outcomes of Canadian children hospitalised with periorbital and orbital cellulitis.

METHOD AND ANALYSIS

This is a multisite retrospective cohort study including previously healthy children aged 2 months to 18 years admitted to hospital with periorbital or orbital cellulitis from 2009 to 2018. Clinical data from medical records from multiple Canadian hospitals will be collected, including community and academic centres. Demographic characteristics and study outcomes will be summarised using descriptive statistics, including diagnostic testing, antibiotic therapy, adjunctive therapy, surgical intervention and clinical outcomes. Variation will be described and evaluated using χ² test or Kruskal-Wallis test. Generalised linear mixed models will be used to identify predictors of surgical intervention and longer length of stay.

ETHICS AND DISSEMINATION

Approval of the study by the Research Ethics Board at each participating site has been obtained prior to data extraction. Study results will be disseminated by presentations at national and international meetings and by publications in high impact open access journals. By identifying important differences in management and outcomes by each hospital, the results will identify areas where care can be improved, practice standardised, unnecessary diagnostic imaging reduced, pharmacotherapy rationalised and where trials are needed.

Impact of Sinus Surgery on Hospital Utilization for Complications of Sinusitis

BACKGROUND

Sinusitis complications are potentially lethal conditions that generally require extensive treatment and thus place a significant burden on the health-care system. The purpose of this study was to assess the impact of surgery on hospital utilization associated with treatment of sinusitis complications.

METHODS

Retrospective cohort study using a national hospital database. The 2012 to 2013 National Inpatient Sample was queried for adult patients with sinusitis and complications. Patients were grouped based upon the presence or absence of sinus procedures. Patient demographics and health status, hospital characteristics, length of stay (LOS), and charges were determined.

RESULTS

Of 1645 patients with sinusitis and associated complications, 232 (14%) underwent sinus procedures. These patients had higher LOS (8.0 ± 7.3 days vs 4.3 ± 5.2 days; P < .001) and charges (US$96 107 ± 108 089 vs US$30 661 ± 47 138; P < .001) than nonprocedure patients. Increased time to procedure in one operation patients (n = 209) of more than 2 days increased total LOS (11.4 ± 9.3 days vs 6.2 ± 5.5 days; P < .001) and charges (US$120 306 ± 112 748 vs US$76 923 ± 81 185; P = .005). Patients with multiple sinus procedures (n = 23) versus one had increased LOS and charges, despite no time difference from admission to first procedure (P = .35). On regression analysis, sinus procedure patients had excess LOS of 0.827 days and charges of US$36 949.

CONCLUSION

Although often necessary, sinus procedures lead to increased LOS and charges. As prolonged time to sinus procedure and revision operations also increase charges, shorter trials of medical therapy and earlier surgical intervention may improve outcomes and reduce costs.

Trend of surgery for orbital cellulitis: An analysis of state inpatient databases

OBJECTIVES/HYPOTHESIS

To evaluate the trend and factors associated with surgical management of orbital cellulitis.

STUDY DESIGN

Retrospective database study.

METHODS

Study using the State Inpatient Databases (SIDs) from 2008 to 2015. Patients with an International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis code for orbital cellulitis were identified in the SIDs for the following states: Arkansas, Florida, Iowa, Maryland, Nebraska, New York, and Wisconsin. Surgery was defined as an ICD-9-CM procedure code for orbitotomy and/or functional endoscopic sinus surgery. The trend of surgery over time was evaluated using the Cochran-Armitage test. Multivariable logistic regression models were used to identify patient- and hospital-level factors associated with surgery.

RESULTS

From 2008 to 2013, the number of hospitalizations for orbital cellulitis ranged from 1,349 to 1,574, but declined to 865 in 2014. From 2008 to 2015, the number of surgeries ranged from 103 to 154. For children (n = 3,041), age, ophthalmologic comorbidity, and conjunctival edema were significantly associated with surgery, whereas for adults (n = 7,961), male gender, private insurance, optic neuritis, and cranial nerves III/VI/VI palsy were associated with surgery.

CONCLUSIONS

Although the number of inpatient hospitalizations for orbital cellulitis has markedly declined, the number of surgeries for orbital cellulitis has remained fairly stable, leading to an observed higher proportion of hospitalized patients undergoing surgery. Future directions include extending the time frame to the present day to assess current rates of hospitalization and surgery. Knowledge of surgical trends and patient- and hospital-level characteristics associated with surgery may help improve management guidelines for and understanding of this vision-threatening disease.

Common Orbital Infections ~ State of the Art ~ Part I

Infections of the orbit and periorbita are relatively frequent, and can cause significant local and systemic morbidity. Loss of vision occurs in more than 10% of patients, and systemic sequelae can include meningitis, intracranial abscess, and death. Numerous organisms infect the orbit, but the most common are bacteria. There are many methods through which orbital infections occur, with infection from the neighboring ethmoid sinuses the most likely cause for all age groups. Prompt management is essential in suspected orbital cellulitis, and involves urgent intravenous antibiotics, rehydration, and treatment of any co-existent underlying systemic disease, e.g., diabetes, renal failure. This review summarizes the common infectious processes of the orbit in both pediatric and adult groups. We review pathophysiology, symptoms, signs, and treatment for infectious orbital processes.

Complications of sinusitis

BACKGROUND

Sinusitis is a common disorder associated with significant patient symptomatology that adversely affects quality of life. Sinusitis can cause further morbidity and mortality through its impact on comorbid disorders, progression of inflammation, and extension of infection.

OBJECTIVE

This review highlights common complications of acute bacterial rhinosinusitis (ABRS) and chronic rhinosinusitis (CRS).

RESULTS

ABRS is complicated by orbital infections, such as pre- or postseptal cellulitis, and by intracranial infections, including abscesses of the epidural and subdural spaces. CRS can contribute to asthma, sleep disordered breathing, and smell disorders. CRS can be complicated by development of allergic fungal rhinosinusitis or deformity of surrounding bony structures. Fungal complications contribute to morbidity and mortality.

CONCLUSION

Complications of ABRS, although relatively rare, can cause significant morbidity and mortality, and must be promptly recognized. CRS commonly complicates or drives comorbid diseases, which adversely impacts quality of life. Treatment of these complications often requires coordinated multidisciplinary care.

Management of frontal sinusitis-associated subperiosteal abscess in children less than 9 years of age

PURPOSE

To investigate practice patterns for cases of subperiosteal abscess (SPA) with concomitant frontal sinusitis to identify factors favorable to medical management in children <9 years of age.

METHODS

The medical records of all pediatric cases of orbital and periorbital cellulitis admitted at a tertiary care center from 1999-2014 were reviewed retrospectively. Cases were included if radiography demonstrated sinusitis-associated SPA in children <9 years of age. Cases of SPA with ipsilateral frontal sinusitis were compared to cases of SPA without ispilateral frontal sinus involvement.

RESULTS

A total of 21 cases with ipsilateral frontal sinusitis and 76 without were included. Patients with frontal sinusitis had a higher incidence of nonmedial SPA compared to those without frontal sinus involvement (6/21 vs 5/76, P = 0.01). Yet a majority of SPAs in the frontal sinusitis group were located medially (15/21 [71%]). All patients with superior or superomedial SPA underwent early surgical intervention. However, 14 of 15 patients (93%) in the frontal sinusitis cohort with medial SPAs were managed successfully with medical therapy alone.

CONCLUSIONS

Medical management of frontal sinusitis-associated SPA appears safe for select children <9 years of age with medial abscess. Although frontal sinusitis is cited as a criterion for surgical drainage of SPA, this criterion should be refined to frontal sinusitis with superiorly located abscesses.

Facial fracture repair and diabetes mellitus: An examination of postoperative complications

OBJECTIVES/HYPOTHESIS

Our objectives included using a nationally representative resource to evaluate charges, demographics, and complication rates among diabetics undergoing surgical repair of facial fractures.

METHODS

We evaluated the Nationwide Inpatient Sample, a database encompassing nearly 8 million hospitalizations, for patients with a diagnosis of a facial fracture who underwent surgical intervention during their hospitalization. Patients were organized by whether they had a diagnosis of diabetes mellitus (DM).

RESULTS

Of 45,509 inpatients included, diabetics had greater costs, longer length of stays, and were significantly more likely to have a host of baseline comorbidities. On multivariate logistic regression corrected for age, race, gender, and preexisting cardiac disease, DM patients had significantly greater odds for cardiac complications (3.3; P < 0.001) and hepatic failure (15.0; P = 0.007). There were no significant differences associated with DM in the rates of enophthalmos, epiphora, and diplopia among patients with orbital fractures. Diabetics did have a significantly greater risk of postoperative infection after mandible repair.

CONCLUSION

In addition to a significant association with greater length of stay and increased hospital charges, DM patients undergoing surgical repair of facial fractures had a significantly greater risk of postoperative complications, including cardiac complications. Diabetics undergoing mandible repair had a greater risk of postoperative infection, even upon controlling for demographic factors, suggesting the need for further study evaluating the role of postoperative antibiotic prophylaxis in this patient population. These findings reveal the potential value of developing and using standardized postoperative care algorithms aimed at minimizing complications in this susceptible population.
