Is Insurance Payer Associated With Hospital Admission of Emergency Department Patients With Mandible Fractures?

BACKGROUND: There is a lack of consensus on the optimal triage pathway for emergency department (ED) patients with mandibular fractures. It remains unclear if patient insurance payers predict hospital admission given potentially competing logistical and health system incentives. PURPOSE: To generate nationally representative estimates of the frequency of hospital admission and its association with primary insurance payers for ED patients with mandible fractures. METHODS: This retrospective cohort study used the 2018 Nationwide Emergency Department Sample, the largest all-payer database in the United States, to identify patients with mandible fractures. The database includes a stratified sample with discharge weights to generate nationally representative estimates. Patients with other facial fractures and/or concomitant injuries that independently warranted admission were excluded. PREDICTOR: The primary predictor variable was primary payer (public, private, self-pay, and other/no charge). OUTCOME VARIABLE: The primary outcome variable was hospital admission (yes/no). COVARIATES: Covariates included patient-, medical/injury-, and hospital-related variables. ANALYSES: Descriptive statistics, along with bivariate and multivariate logistic regression with Bonferroni correction, were used to produce national estimates and identify predictors of admission. P < .01 was considered significant. RESULTS: The cohort included 27,238 weighted encounters involving isolated mandible fractures, of which 5,345(20%) were admitted. The payers for admitted patients were 46% public, 25% private, 22% self-pay, and 7% no charge/other. In bivariate analyses, public insurance was associated with a higher likelihood of admission than private insurance (RR 1.24, 95% CI 1.06 to 1.45), though there was no association in the multivariate model (OR 1.03, 95% CI 0.83 to 1.28). In multivariate analysis, higher Charlson Comorbidity Index (OR 1.32, 95% CI 1.18 to 1.48), alcohol-related disorder (OR 3.47, 95% CI 2.74 to 4.39), substance-related disorder (OR 1.43, 95% CI 1.20 to 1.71), and more mandible fractures (OR 3.08, 95% CI 2.65 to 3.59) were associated with admission. Compared to body fractures, subcondylar (OR 3.83, 95% CI 2.39 to 6.14), angle (OR 3.53, 95% CI 2.84 to 6.09), and symphysis (OR 4.14, 95% CI 2.84 to 6.09) fractures had higher odds of admission. Finally, level I (OR 4.11, 95% CI 2.41 to 6.98) and level II (OR 3.16, 95% CI 1.85 to 5.39) trauma centers had higher odds of admission. CONCLUSIONS: In 2018, 20% of ED patients with isolated mandible fractures were admitted. Several patient and hospital characteristics were predictors of admission. Insurance status was not associated with admission.

Open reduction and internal fixation of mandibular condylar fractures: A national inpatient sample analysis, 2005-2014.

The purpose of this study was to compare outcomes of open reduction and internal fixation (ORIF) versus closed reduction (CR) for mandibular condylar fractures.Patients included in the National Inpatient Sample (NIS) database (2005-2014) who were admitted to the hospital for unilateral mandibular condylar fracture were included in the analysis. Patient characteristics and clinical outcomes were compared between those who received ORIF and those receiving CR. Logistic regression analysis was performed to estimate odds ratios (ORs) for each aspect of the main observed events.NIS data of 12,303 patients who underwent ORIF and 4310 patients who underwent CR were analyzed. Compared to CR, ORIF had an increased risk of longer hospital stay (adjusted OR [aOR] = 1.78, 95% confidence intervals [CIs] = 1.51-2.09), higher total medical cost (aOR = 2.57, 95% CI = 2.17-3.05), and hematoma development (aOR = 10.66, 95% CI = 1.43-75.59), but had a lower risk of having wound complications (aOR = 0.86, 95% CI = 0.79-0.93).Patients with mandibular condylar fractures who receive ORIF have greater risk of having an extended hospital stay, higher total medical costs, and hematoma development but lower risk of experiencing wound complications compared to those who receive CR.

On-Site 3-Dimensional Printing and Preoperative Adaptation Decrease Operative Time for Mandibular Fracture Repair.

PURPOSE: The purpose of this study was to compare the intraoperative time and operating room costs between patients with mandibular fractures treated with traditional adaptation and fixation and patients treated with preadapted plates created with on-site 3-dimensionally printed models. PATIENTS AND METHODS: We designed a prospective comparative cohort study for patients with mandibular fractures. The control group received traditional open reduction and internal fixation of their mandibular fractures. For the patients in the experimental group, a 3-dimensional (3D) model of the fractured mandible was made using an on-site 3D printer. The model then underwent osteotomy, if needed, and the plate was adapted to the model, submitted to sterilization, and implanted in the patient. The primary outcome variable was intraoperative plating time, and the secondary outcome variable was operating room cost. The groups were compared by the Wilcoxon signed rank test. RESULTS: The 38 patients included in the study had a mean age of 39.6 years, and male patients comprised 81.6%. The mean time for intraoperative plate adaptation was 22.8 ± 2.1 minutes in the control group and 6.9 ± 0.3 minutes in the experimental, 3D printed group (P < .0001). In the experimental group, 4 patients (21%) required a single intraoperative corrective bend. The calculated average cost per patient based on the average operating costs at our institution was $2,306.45 in the control group and $698.00 in the experimental group. CONCLUSIONS: This study shows that the use of 3D printers for fabrication of models to prebend maxillofacial reconstruction plates is associated with decreased operating room time and costs. Using an on-site 3D printer requires minor start-up and use costs and results in a significant reduction in operating room time, which remains one of the most expensive aspects of facial trauma care.

Development of a financially viable model for the management of mandibular fractures as day cases in a level 1 major trauma centre.

There is a subgroup of patients with mandibular fractures who could safely and effectively be managed in an outpatient day-care unit. Suitability depends on medical, social, and operative factors, and identification of the correct criteria will govern management after that in the emergency department. Reduced use of beds would lead to less money being spent on emergency treatment, and increased capacity for elective surgery. The aims of this study were to identify a group of patients with mandibular fractures whose duration of operation and period of recovery would be suitable for treatment in the day-care unit, and to evaluate the potential financial benefits. Inpatients were assessed for day surgery using medical, social, and surgical criteria. Each patient's suitability for discharge was assessed two, three, and five hours postoperatively. A financial feasibility study was made retrospectively on a larger sample of patients with mandibular fractures. The discharge criteria from the day-care unit were fully met by 26/40 patients at five hours postoperatively, mean (range) duration of operation was 145 (40-285) minutes, and mean (SD) Mandibular Injury Severity Score was 13 (3), range 7-20. When all the criteria were combined (n=100), 12 of the patients were suitable for day care. With 24 bed-day savings/100 patients, potential earnings would increase to around £80 000/year at this hospital. In conclusion, we have identified a group of patients who were suitable for management of mandibular fractures in the day-care unit. Considerable cost savings are anticipated.

Maxillomandibular Fixation by Plastic Surgeons: Cost Analysis and Utilization of Resources.

PURPOSE: Maxillomandibular fixation (MMF) can be performed using various techniques. Two common approaches used are arch bars and bone screws. Arch bars are the gold standard and inexpensive, but often require increased procedure time. Bone screws with wire fixation is a popular alternative, but more expensive than arch bars. The differences in costs of care, complications, and operative times between these 2 techniques are analyzed. METHODS: A chart review was conducted on patients treated over the last 12 years at our institution. Forty-four patients with CPT code 21453 (closed reduction of mandible fracture with interdental fixation) with an isolated mandible fracture were used in our data collection. The operating room (OR) costs, procedure duration, and complications for these patients were analyzed. RESULTS: Operative times were significantly shorter for patients treated with bone screws (P < 0.002). The costs for one trip to the OR for either method of fixation did not show any significant differences (P < 0.840). More patients with arch bar fixation (62%) required a second trip to the OR for removal in comparison to those with screw fixation (31%) (P < 0.068). This additional trip to the OR added significant cost. There were no differences in patient complications between these 2 fixation techniques. CONCLUSIONS: The MMF with bone screws represents an attractive alternative to fixation with arch bars in appropriate scenarios. Screw fixation offers reduced costs, fewer trips to the OR, and decreased operative duration without a difference in complications. Cost savings were noted most significantly in a decreased need for secondary procedures in patients who were treated with MMF screws. Screw fixation offers potential for reducing the costs of care in treating patients with minimally displaced or favorable mandible fractures.

The cost and inpatient burden of treating mandible fractures: a nationwide inpatient sample database analysis.

OBJECTIVE: To discuss patient demographics, hospitalization characteristics, and costs associated with the treatment of mandible fractures. STUDY DESIGN: Cross-sectional study. SETTING: The 2009 Nationwide Inpatient Sample (NIS) database. SUBJECTS/METHODS: Patient demographics, hospital characteristics, fracture locations, and common comorbidities for patients with isolated mandible fractures were analyzed, and variables associated with increased cost and length of hospitalization stay were ascertained. RESULTS: A total of 1481 patients were identified with isolated mandible fractures. The average age was 32, 85.4% were male, 39% were Caucasian, and 25% African American. Forty percent were from the lowest median household income quartile, and 77% were uninsured or government funded. The average length of stay (LOS) was 2.65 days, and average hospitalization cost was $35,804. A statistically significant increased LOS was associated with alcohol abuse, drug abuse, mental illness, diabetes mellitus type 2, cardiovascular disease, HIV, and age over 40. There was a statistically significant increased total cost associated with drug abuse, alcohol abuse, mental illness, cardiovascular disease, and age over 40. CONCLUSION: The average cost for treatment of mandible fractures was $35,804 per person with increased expenditures for older patients and those with a history of mental illness, cardiovascular disease, or substance abuse. To improve outcomes and reduce hospital charges, outpatient resources and inpatient protocols should be implemented to address the factors we identified as contributing to higher costs and increased hospital stay.

Patient perceptions on physician reimbursement in plastic surgery.

BACKGROUND: Public perception on physician reimbursement may be that considerable payments are received for procedures: a direct contrast to the actual decline. We aim to investigate patient perceptions toward plastic surgeon reimbursements from insurance companies. METHODS: A survey of 4 common, single-staged procedures was administered to 140 patients. Patients were asked for their opinion on current insurance company reimbursement fees and what they believed the reimbursement fee should be. RESULTS: Eighty-four patients completed the survey. Patients estimated physician's reimbursements at 472% to 1061% more for breast reduction, 347% to 770% for abdominal hernia reconstruction, 372% to 787% for panniculectomy, and 290% to 628% for mandibular fracture repair. Despite these perceived higher-than-actual-fee payments, 87% of patients thought reimbursements should still be higher. CONCLUSIONS: Patients surveyed overestimated plastic surgery procedure fees by 290% to 1061%. Patients should be informed and educated regarding current fee schedules to plastic surgeons to correct current misconceptions.

Mandibular fractures treated with small plates and screws reduce treatment cost.

PURPOSE: The efficacy of treating mandibular fractures with open reduction and internal fixation (ORIF) using small titanium plates and monocortical screws is well established. The purpose of this study was to determine whether the use of semirigid (small) titanium plates results in lower treatment charges. PATIENTS AND METHODS: Consecutive patients with mandibular fractures were randomly allocated to ORIF with small or large titanium plates. The primary predictor variable for this secondary subset analysis was plate size. The primary outcome variable was total treatment charges. Other outcomes included length of stay (LOS), operating room charges, hardware charges, LOS charge, and charges related to the treatment of complications. RESULTS: A total of 127 consecutive patients were enrolled in the study. Fifty-two patients completed the required 6-week follow-up and had data available for analysis. Adjusted total treatment charges suggested a significant difference, with a mean total treatment charge of $15,308 in the semirigid group and a mean total treatment charge of $16,557 in the rigid group (P = .04). Total treatment charges were 8% higher in the rigid group compared with the semirigid group. CONCLUSIONS: The findings of this study suggest that the overall charges associated with treating mandibular fractures with ORIF are significantly lower when semirigid plates are used.

The cause of cost in the management of odontogenic infections 1: a demographic survey and multivariate analysis.

PURPOSE: The purpose of this retrospective cohort study was to describe the demographics of patients with odontogenic infections and to evaluate the costs associated with the demographic, social, treatment, and hospital course variables in patients hospitalized for odontogenic infections. MATERIALS AND METHODS: A retrospective chart review was conducted in patients admitted for odontogenic infections at Harborview Medical Center from July 1, 2001, through June 30, 2011. RESULTS: In total, 318 patient charts were reviewed and included. The unsponsored portion of the patient population increased from 14.7-61.9% over the course of the study. The average hospital bill per patient in this study was $17,053. Of the $5,422,854 billed, only $1,528,869 was received by the hospital in payment for services rendered, equating to $3,893,985 in lost potential revenue. The variables location of treatment, length of stay, length of stay in the intensive care unit, additional use of the operating room, and antibiotic regimen accounted for 90.2% of the variation in the hospital bill. CONCLUSION: Unsponsored patients constituting 61.9% of the patient population represent an enormous challenge for hospitals and providers. To maintain the standard of care for all patients and still be able to provide care to patients without insurance, county hospitals and academic institutions must seek to improve cost efficiency. The present findings reinforce the need to be vigilant about the decision to admit, take to the operating room, admit to an intensive care unit, and discharge to lower the costs to the patient, hospital, and society for the management of odontogenic infections.

The financial burden of mandibular trauma.

PURPOSE: Patients with mandibular trauma in the greater Seattle region are frequently transferred to Harborview Medical Center (HMC) despite trained providers in the surrounding communities. HMC receives poor reimbursement for these services, creating a disproportionate financial burden on the hospital. In this study we aim to identify the variables associated with increased cost of care, measure the relative financial impact of these variables, and quantify the revenue loss incurred from the treatment of isolated mandibular fractures. MATERIALS AND METHODS: A retrospective chart review was conducted of patients treated at HMC for isolated mandibular fractures from July 1999 through June 2010, using International Classification of Diseases, Ninth Revision and Current Procedural Terminology coding. Data collected included demographics, injury, hospital course, treatment, outcomes, and billing. RESULTS: The study included 1,554 patients. Total billing was $22.1 million. Of this, $6.9 million was recovered. We found that there are multiple variables associated with the increased cost of treating mandibular fractures; 4 variables--length of hospital stay, treatment modality, service providing treatment, and method of arrival--accounted for 49.1% of the total variance in the amount billed. In addition, we found that the unsponsored portion of our patient population grew from 6.7% to 51.4% during the study period. CONCLUSIONS: Our results led to specific cost-efficiency recommendations: 1) perform closed reduction whenever possible; 2) encourage performing procedures with patients under local anesthesia (closed reductions and arch bar removals); 3) provide improved and shared training among the services treating craniofacial trauma; 4) encourage arrival by privately owned vehicle; 5) provide outpatient treatment, when applicable; 6) offer provider incentives to take trauma call; and 7) offer hospital incentives to treat patients and not transfer them.

An alternative method in mandibular fracture treatment: bone graft use instead of a plate.

In the treatment of the mandibular fractures, one of the main principles is to use the least amount of foreign material. We present an alternative technique that the bone grafts harvested from the fracture borders or from the iliac crest were used instead of plates and the fixation was done with screws. In the study including 24 mandible fractures, the bone grafts harvested from the fracture borders were used in the 10 favorable fractures and the bone grafts harvested from the iliac crest were used in the 14 unfavorable fractures. In the combined mandible fractures, four fractures were fixated with titanium plates and the other side with the bone graft. The patients, who were followed up for 12 to 20 months, were evaluated with macroscopic occlusion, panoramic graphs, and three-dimensional computerized tomographs. The advantage of this technique of fixation with the autogenous tissue is reduced infection rates and reduced operation costs. In the pediatric patients, the second session operation of plate removal is not necessary.

Baseline characteristics and treatment preferences of oral surgery patients.

PURPOSE: Patient preferences for treatment choices may depend on patient characteristics. Using standard gamble (SG) and willingness to pay (WTP), this study compares preferences for treatment of mandibular fracture among patients in a low-income urban area. PATIENTS AND METHODS: Surveys of African-American and Hispanic adults receiving treatment at King/Drew Medical Center for either mandibular fracture (n = 98) or third molar removal (n = 105) were used to investigate differences in patient characteristics across treatment groups (third molar vs fracture) and treatment preference (wiring vs surgery). RESULTS: The fracture patients were willing to pay more to restore function without scarring or nerve damage than were the third molar patients. Patients who chose surgery were willing to accept a greater risk of possible nerve damage or scarring than those who chose wiring. Among 15 potential predictors of SG and WTP studied in 4 subgroups defined by actual treatment and treatment preference, significant predictors varied, with associations for education and clinical experience for SG and associations with income and psychosocial predictors for WTP. CONCLUSIONS: SG and WTP capture different domains of health values in patients. There is considerable heterogeneity in relationships among patient characteristics and patient preferences across subgroups defined by actual treatment and treatment preferences.

Third molar complications requiring hospitalization.

OBJECTIVE: The aim of this study was to describe demographic and clinical patterns of subjects hospitalized with complications associated with third molars (M3). STUDY DESIGN: The investigation was designed as a prospective cohort study composed of subjects admitted to hospital for management of M3-associated complications. The predictor variable was "clinical status of the M3" defined as (A) prophylactic M3 removal, (B) nonelective M3 removal, or (C) M3 present at the time of admission. Outcome variables were infection parameters, treatment costs, length of hospital stay, and days of disability. Postoperative complications (A and B) were compared to complications based on pericoronitis (C). Complications due to prophylactic removal (A) were compared to those arising from pericoronitis or from the removal of symptomatic teeth (B and C). RESULTS: From January 2003 to December 2004, 45 deep space infections, 6 mandibular fractures, 2 lingual nerve injuries, 1 parapharyngeal tooth luxation, and 1 osteomyelitis were noticed. Fifteen complications resulted from prophylactic surgery (A), 25 from nonelective removal (B), and 15 from pericoronitis (C). Direct treatment costs were 147,000 euro (A: 42,000 euro; B: 74,000 euro; C: 31,000 euro). In 10 of the 15 patients of group C, deep space involvement resulted immediately from the first episode of pericoronitis. Neither clinical markers of infection nor economic parameters showed significant differences between the groups. CONCLUSION: Within the catchment area of our institution, the majority of third molar-related hospitalizations resulted from diseased third molars or their removal.

Cost-effective management of isolated facial fractures.

The purpose of this study was to evaluate the subset of costs incurred for surgical treatment of isolated midface and mandible fractures of patients admitted directly from the emergency department compared with those admitted as outpatients after evaluation and discharge from the emergency department. After institutional review board approval, the records of patients admitted to Wake Forest University Baptist Medical Center were studied retrospectively for patients who underwent surgical repair of an isolated facial fracture between July 1, 1999 and June 30, 2000. Patients were placed into one of two groups: admission from the emergency department versus admission as an out-patient. Total hospital charges were compared, and complications were evaluated. Mechanism of injury, age, and gender were recorded within each group. Forty-two patients met the study criteria. Twenty-eight patients were admitted directly from the emergency department (Group A), and 14 were admitted as outpatients after elective scheduling for operative repair (Group B). Operative charges based on utilization of time and materials showed no statistical significance between Group A (P = 0.275) and Group B (P = 0.393). Patients admitted directly from the emergency department had a mean hospital charge of 3,556.66 dollars higher (P< or = 0.001) and stayed 2 days longer in the hospital as compared with the outpatient group. No differences were noted in complications between the study groups. The results of this study reveal a significant decrease in cost for patients with isolated facial fractures admitted as outpatients on scheduling surgery as compared with immediate admission from the emergency department.

[Correlation between the real cost of an intervention and cost factors in France: example of removal of jaw fixation material in mandibular fractures]. / Etude de la corrélation entre le coût réel d'une intervention et ses modes de facturation en France: exemple de l'ablation de matériel d'ostéosynthèse de mandibule.

INTRODUCTION: economic cost is a timely topic which will have to be taken in consideration more and more for determining the appropriate indication for surgical procedures. "Health has no price, but it has a cost" is a common proverb urging us to think in terms real cost of a surgical procedure. The purpose of this study is to estimate the real cost of a usual and frequent intervention: removal of osteosynthesis material in mandibular fractures. Real cost was compared with the cost charged by the French health insurance fund. MATERIAL AND METHODS: this retrospective study collected all the interventions concerning material removal after mandibular fractures performed in our department during 2002. The following parameters were retained: the number of consultations, the duration of occupation of the surgical unit and the recovery room, the list of materials and products used, the cost of the medical staffs and cleaning agents, the duration of hospitalization, other administrative loads and expenses. RESULTS: a series of 30 patients was found, each patient had had three consultations, the average duration of hospitalization was 36 hours, the time of occupation of the surgical unit was 100 minutes and occupation of the recovery room was 2 hours. The total real cost of this intervention was 510 Euros, the cost estimated by the health insurance fund was 110 Euros and the cost of hospitalisation charged was 997 Euros. CONCLUSION: these results show us the real cost of this intervention and the cost estimated by the French health insurance fund. It is highly noteworthy that the cost estimates were totally inadequate. This study leads to a discussion concerning a more global approach to the cost-benefit ratio of such an intervention as well as the indication for bioabsorbable material compared with titanium in facial traumatology.

[Cost of miniplate osteosynthesis for treatment of mandibular fractures: a prospective evaluation]. / Kosten der Unterkieferfrakturversorgung: Eine prospektive Untersuchung.

PURPOSE: Up to now in maxillofacial surgery almost all inpatient treatments were reimbursed at the hospital's per diem rate. The real treatment cost is unknown and there is a lack of publications in this sphere. This study calculates the cost of surgical treatment of mandibular fractures. METHOD: The prospective study includes 104 patients whose mandibular fractures were treated using miniplate osteosynthesis. For each patient we took into account the time input by physicians and specialised nurses and calculated labour cost using the relevant wage rates. We added the cost for materials and drugs as well as for laboratory and radiographic examinations. Finally, we incorporated charges for the hotel and nursing components of inpatient treatment. RESULTS: The cost for the surgical treatment of mandibular fractures varied between 642 euro; for single and 1,070 euro; for triple fractures. The share of labour cost is about 1/3. Treatment cost varies with the length of hospital stay: 1,132 euro; for four days and 1,628 euro; for seven days on average. CONCLUSION: This prospective study can be compared with the recently published corresponding G-DRG rates. Moreover, the reported cost figures allow comparison with corresponding cost studies from other public health systems.

Cost-based analysis of the treatment of mandibular fractures in a tertiary care center.

BACKGROUND: The objective of this study was to assess the cost effectiveness of alternative treatment algorithms for the management of isolated mandibular fractures. METHODS: This is an institutional review board-approved retrospective study consisting of a chart review of 25 patients who underwent operative repair of an isolated mandible fracture between July 1, 1999, and June 30, 2000. Patients were stratified into two groups: patients who were immediately admitted to the hospital from the emergency department (ED) versus patients who were discharged from the ED and who returned for elective scheduled operative repair. Patients' total hospital charges were compared on the basis of operating room (OR) time, operative materials, and hospital charges. RESULTS: Seventeen of the study patients were directly admitted from the ED, and eight underwent elective scheduled operative repair. Of the patients directly admitted from the ED, the mean age was 34.9 years (range, 19-57 years), and the study population consisted of 16 men and 1 woman. This group had a mean OR time of 161 minutes, a mean OR time charge of $1,978.66, a mean OR supply charge of 1,049.43 US dollars, a mean hospital floor charge of 5,041.02 US dollars, and an average hospital stay of 2.82 days. The treatment group of patients undergoing scheduled operative repair (n = 8) had a mean age of 30.3 years (range, 19-49 years), and all were men. This second treatment group had a mean OR time of 167.1 minutes, a mean OR time charge of 2,162.03 US dollars, a mean OR supply charge of 871.00 US dollars, a mean hospital floor charge of 2,759.38 US dollars, and a mean hospital stay of 0.88 days. Comparison of the two study groups demonstrated operative charges were made on the basis of time and materials and were shown to have no statistically significant difference (p = 0.753 and p = 0.289, respectively). Comparison of hospital charges revealed that patients admitted directly from the ED had a mean charge 2,276.70 US dollars higher (p = 0.019) and stayed 1.95 days longer in the hospital than patients discharged from the emergency department who returned for elective scheduled repair. There were two complications in the study patients; both occurred in the group admitted directly from the emergency room. CONCLUSION: The results of this study indicate that the most cost-effective management of an isolated mandibular fracture is initial evaluation in the ED with elective interval operative repair. This management protocol is, of course, only applicable if the patient is clinically stable and has no other injuries or comorbidities necessitating in-hospital observation.

A financial analysis of maxillomandibular fixation versus rigid internal fixation for treatment of mandibular fractures.

PURPOSE: The aim of this study was to compare the cost-effectiveness of mandibular fracture treatment by closed reduction with maxillomandibular fixation (CRF) with open reduction and rigid internal fixation (ORIF). PATIENTS AND METHODS: This was a retrospective study of 85 patients admitted to the Oral and Maxillofacial Surgery Service at San Francisco General Hospital and treated for mandibular fractures from January 1 to December 31, 1993. The patients were divided into 2 groups: 1) those treated with CRF and 2) those treated with ORIF. The outcome variables were length of hospital stay, duration of anesthesia, and time in operating room. The charge for primary fracture treatment included the fees for the operation and hospitalization without any complications. Within the group of 85 patients treated for mandibular fractures in 1993, 10 patients treated with CRF and 10 patients treated with ORIF were randomly selected, and hospital billing statements were used to estimate the average charge of primary treatment. The average charge to manage a major postoperative infection also was estimated based on the billing statements of 10 randomly selected patients treated in 1992 (5 treated with CRF, 5 with ORIF) who required hospital admission for the management of a complication. The average total charge was computed by using the average charge for primary treatment plus the incidence of postoperative infection multiplied by the average charge for management of that complication. RESULTS: Eighty-five patients were included in the study. The average charge for primary treatment was $10,100 for the CRF group and $28,362 for the ORIF group. The average charge for the inpatient management of a major postoperative infection was $26,671 for the CRF group and $39,213 for the ORIF group. The average total charge for management of a mandible fracture with CRF was $10,927; the total charge for the ORIF group was $34,636. CONCLUSION: The results of this retrospective study suggest that the use of CRF in the management of mandibular fractures at our institution provides considerable savings over treatment by using ORIF. The use of ORIF should be reserved for patients and fracture types with specific indications.

Population-based analysis of 10,766 hospitalizations for mandibular fractures in California, 1991 to 1993.

BACKGROUND: This study describes mandibular fracture incidence, causes, and consequences in a large population. METHODS: California hospital discharge data from 1991 to 1993 were examined to describe causes, lengths of stay, and hospital charges for patients hospitalized for mandibular fractures. Rates were calculated per 100,000 population. RESULTS: There were 10,766 discharges with mandibular fracture as principal diagnosis or as diagnoses two through five on the discharge record (rate=11.5). Of these, 2,694 had mandibular fracture as the only diagnosis (principal diagnosis). For all 10,766 cases, assaults were responsible for more than half (54.0%) of all admissions for mandibular fracture. The highest rates were found among males (18.7), blacks (43.0), and adults aged 16 to 20 (26.5). Charges for the initial hospitalization (excluding physician's fees) for the 2,694 cases with only a diagnosis of mandibular fracture were used to estimate mean charges ($8,740). The total extrapolated 1993 inflation-adjusted hospital charges for mandibular fractures were $34 million per year. Most patients' bills were submitted to government payers, such as Medicaid. CONCLUSION: Treatment of mandibular fractures represents a considerable cost to public-supported programs as well as to patients.

Complications of mandibular fractures.

Timely repair of mandibular fractures remains an effective means to reduce pain, restore function, and prevent complications. This study addresses the effect of the time interval between injury and treatment on the overall complication rate, the complication rate between various treatment modalities (mandibular-maxillary fixation [MMF] alone, MMF with intraosseous wire bone fixation, and MMF with rigid internal fixation), and the relationship of inpatient vs. outpatient management. Cost was also examined with respect to choice of management. We report a retrospective series of 308 consecutive patients managed at the University of Miami/Jackson Memorial Hospital. Patients who received treatment 3 to 10 days following injury were found to have a lower complication rate than earlier or later repair. We postulate that most patients with mandibular fractures may be managed on an outpatient basis, which represents a considerable savings in cost.
