Inequality of Access to Surgical Specialty Health Care: Why Children With Government-Funded Insurance Have Less Access Than Those With Private Insurance in Southern California

Objective. More than 25 million children in the United States are dependent on federal and state medical insurance programs for their health care needs. In California, 3.25 million children depend on Medi-Cal for their health insurance. In Southern California alone, the figure is as high as 1.81 million. However, 9.30 million children nationally and 1.55 million in California have no health insurance. Various public policies that would increase enrollment in these programs are being discussed to address this problem. However, before their implementation, it is important to understand what impact such policies would have on the actual delivery of health care to this patient population. In California, 2 predominant health care delivery models exist for Medi-Cal: a fee-for-service (so-called regular or straight Medi-Cal) and a managed care plan. One third of the children in Medi-Cal in the state are enrolled in the fee-for-service plan with the remainder in the managed care plan, whereas in Southern California, this figure is slightly lower at 28% in the fee-for-service plan. The objective of this study was to determine the number of otolaryngologists in Southern California who would offer a new patient appointment for an evaluation for tonsillectomy for a child with commercial insurance versus government-funded (Medi-Cal) insurance through direct contact with the physician and to determine whether the surgeon would offer to perform the procedure or refer the patient to another institution and to identify the specific reason(s) for any disparity in access to health care. Methods. A written questionnaire was sent via regular mail to 303 otolaryngologists in the Southern California area in 2003. Results. A total of 100 fully completed questionnaires were received. Ninety-seven surgeons would offer an office appointment to a child with commercial insurance as compared with only 27 for a child with Medi-Cal. Of those 27 surgeons, 8 would then refer the child to another physician to perform the surgery, and only 19 would actually offer to perform surgery, if indicated. Reasons provided for not offering an office appointment or surgery for the child with Medi-Cal include excessive paperwork and/or administrative burdens (96%), low monetary reimbursement for the surgery (92%), and low monetary reimbursement for the office visit (87%). Conclusions. There is a tremendous inequality of access to surgical specialty health care for children with government-funded insurance when compared with those with commercial insurance in Southern California. Physicians indicate that this disparity is related to excessive administrative burdens and low monetary reimbursement. The implications of our findings on public health care policies are discussed.

On the origin of tonsillectomy and the dissection method.

Objectives To identify the person or persons responsible for the conception and description of the operation that we know of today as tonsillectomy and to determine whether this was accomplished by an American otolaryngologist(s) before the description by George Waugh of London in 1909.

Age specific differences in pediatric obstructive sleep apnea

BACKGROUND Some have suggested that younger children have a more severe form of obstructive sleep apnea than older children and therefore are at a higher risk for respiratory compromise after tonsillectomy and adenoidectomy. However, at present there are few studies that have identified any significant correlation between age and severity of obstructive sleep apnea. OBJECTIVE To determine if age specific differences in obstructive sleep apnea are present in children. DESIGN Retrospective chart review. SETTING Tertiary care childrens hospital. PATIENTS The records of children (1-18 years of age) with obstructive sleep apnea diagnosed by overnight polysomnography between January 1998 and January 2001 were reviewed. Children included in the study also had evidence of adenotonsillar hypertrophy and had no other co-existing medical problems. MAIN OUTCOME MEASURES Overnight polysomnography was performed in all children. Apnea-hypopnea index (AHI), baseline and lowest O(2) saturation, baseline and peak end tidal CO(2), and total number of obstructive apneas, hypopneas, central apneas and mixed apneas were measured during each polysomnogram. Children were subdivided into the following age groups: 1-2, 3-5, 6-11 and 12-18 years. Polysomnograms were classified into normal, mild, moderate and severe categories. RESULTS Three hundred and sixty-three children were studied; 45 children were ages 1-2 years, 159 children were ages 3-5 years, 137 children were 6-11 years and 22 children were 12-18 years. Although there appears to be a trend towards a greater mean number of obstructive apneas, hypopneas, central apneas, mixed apneas, a higher mean AHI, lower mean SaO(2) nadir, and a higher mean PETCO(2) in the younger age groups when compared to the older groups, a Students t-test demonstrates that there is no statistical significance for most OSA parameters. An analysis of variance using the F-test reveals statistical significance (p<0.01) when children ages 1-2 were compared to those 3-5, 6-11 or 12-18 years of age for the variables AHI, mean number of central apneas, hypopneas and mixed apneas. When comparing patients in the various severity categories, children ages 1-2 years show a distinct distribution with a larger percentage in the moderate to severe categories. Chi square analysis reveals a significant difference between the frequency distribution of children in age group 1-2 years and that of the other age groups (p<0.01). CONCLUSION There is a predilection for children less than 3 years of age to have more severe obstructive sleep apnea as documented by polysomnography. Central apnea also appears to be more common in this age group. These findings may be explained by anatomic and physiologic differences related to age and support a period of observation following adenotonsillectomy in younger children.

Surgical management of type III and IV laryngotracheoesophageal clefts: The three-layered approach §

OBJECTIVE The objective of this paper is to present our surgical experience with a cohort of four infants with laryngotracheoesophageal cleft (LTEC) in order to highlight our early failures and complications and to propose a comprehensive, three-layered approach in treating stages III and IV LTEC. METHOD An IRB approved, retrospective chart review was carried out of a cohort of four cases occurring within a 2-year period of time. RESULTS All patients had other significant anomalies, and the mortality rate was high: 75%. After our initial failures and difficulties with recurrent fistulas, tracheomalacia and tracheotomy dependence, we were able to achieve a successful outcome of a functional separation of the airway and the digestive tract without a tracheotomy in our last two patients. Unfortunately, both these patients died from factors not directly associated with the LTEC so long-term follow up was not possible. We now have one survivor, our second case, who is tracheotomy dependent. CONCLUSION Laryngotracheoesophageal clefts are rare congenital anomalies with high morbidity and mortality despite various forms of surgical repair. Fistulas, tracheostomy dependence, tracheomalacia, and chronic lung disease secondary to aspiration are frequent problems following LTEC repairs. We advocate an anterior approach to the cleft repair, a three-layered closure of the cleft to include an interpositional muscular flap, and a physiologic repair of the posterior larynx with a standard cartilage graft technique used in laryngotracheal reconstruction.

Long-term otologic status of older cleft palate patients.

The purpose of this study was to evaluate the effectiveness of regular otologic care on the long-term outcome in patients with cleft palates. We report the otoscopic and audiologic findings of 50 patients who were followed regularly at our center for an average of 15.4 years. All these patients had their cleft palates repaired by the same surgical team and all ears were examined by one of the authors under the microscope and a chart review completed. Thirty eight patients had at least one tube placement. The physical abnormalities noted were tympanosclerosis (36%), retraction of tympanic membrane (TM) (20%), atrophy of TM (15%), perforation (11%), PE tube in situ (11%), thick TM (6%) and PE tube in middle ear (1%).The examination was normal in 36%. A conductive loss was noted in 18% and sensorineural loss in 3%. The results of this study support the concept of regular otologic care for cleft palate patients even when they are overtly asymptomatic.

Use of the Palmaz stent in the treatment of severe tracheomalacia

To present our experience with the use of the Palmaz stent in treating cases of severe, life-threatening tracheomalacia, and to report our experience with the use of tracheal stents in patients who have concomitant tracheotomies, we performed a retrospective study in a tertiary-care childrens hospital. Nine patients with multiple congenital anomalies including severe tracheomalacia required placement of a Palmaz stent to prolong life. The congenital anomalies included congenital heart disease, congenital lung disease, meningomyelocele, laryngotracheoesophageal cleft, and tracheoesophageal fistula. Three of the patients had concomitant tracheotomies. Each patient had placement of one or more Palmaz stents in the trachea and/or bronchus. Four patients died, and 5 patients are still alive. Three of the 4 patients who died had concomitant tracheotomies and died of complications associated with significant tracheal hemorrhage. The fourth died of pulmonary complications following repeated episodes of pneumonia. None of the 5 patients who are still alive had a concomitant tracheotomy. The Palmaz stent is a useful tool for treating life-threatening tracheomalacia as a final resort in this difficult patient population; however, the use of these stents may lead to subsequent hemorrhage and death, especially in patients with tracheotomies, so their use must be carefully considered.

Histologic analysis of pediatric tonsil and adenoid specimens : Is it really necessary?

OBJECTIVE To evaluate the incidence of unexpected histologic findings in routine tonsillectomy and adenoidectomy specimens. METHODS A retrospective medical record review was performed at a tertiary care childrens hospital. The pathology records of 2062 children who underwent tonsil or adenoid surgery were analyzed and the final histologic diagnosis was recorded. RESULTS Four unexpected histologic findings were found on routine tonsil and adenoid specimens. None were clinically significant. A review of the literature shows a very low rate (0.015%) of unexpected clinically significant diagnoses in pediatric adenotonsillectomy specimens. CONCLUSIONS Given rarity of unexpected clinically significant diagnoses in pediatric adenotonsillectomy specimens, the cost and effort of analyzing each specimen histologically is difficult to justify.

Foreign bodies of the upper aerodigestive tract

Foreign bodies of the upper aerodigestive tract in the pediatric population are a common occurrence. However, despite significant advances in prevention, first aid and endoscopic technology, they remain a diagnostic and therapeutic challenge. Early diagnosis is the key to successful and uncomplicated management of these accidents. An orderly and systematic approach to these patients including a careful history, physical exam and radiographic studies is detailed in this review.

The effect of platelet-derived growth factor on tracheal wound healing.

In order to evaluate a new method for the direct application of a polypeptide growth factor to injured tracheal epithelium and to determine the effect of topical platelet-derived growth factor (PDGF) on tracheal wound healing, a controlled animal study was designed using six adult beagle dogs. Four 2x1 cm mucosal defects were created in the tracheal lumen of each dog for a total of 24 experimental sites. Twelve wounds were treated with PDGF in a collagen-fibrin composite tissue adhesive (CTA) carrier. Eight sites received CTA alone and four were left untreated. Healing was assessed by endoscopic exam on post-operative days 4, 7, 10, 14, 17 and 21. The animals were sacrificed on day 21 and the tracheas were harvested for histological examination of the experimental sites and adjacent unwounded trachea. By 21 days, complete healing of all sites was observed endoscopically. Wounds treated with CTA or PDGF-CTA healed at a faster rate than control sites. The PDGF-CTA treated wounds demonstrated excessive granulation tissue formation. Histological examination demonstrated a higher percentage of wound coverage with ciliated epithelium most similar to normal trachea in the PDGF treated wounds. CTA is effective as a carrier for the direct delivery of a growth factor to injured tracheal epithelium. The application of CTA or PDGF-CTA results in a more rapid rate of tracheal wound healing as compared with control wounds. PDGF-CTA led to increased acute local inflammatory changes but was associated with a structurally more normal respiratory epithelium after healing. Physiological studies are necessary to determine the functional significance of these findings.

Thyroglossal duct remnant surgery: A reliable, reproducible approach to the suprahyoid region

BACKGROUND Recurrence of thyroglossal duct remnants remains a clinical problem despite the success of the Sistrunk procedure. Inadequate excision of disease in the suprahyoid region significantly impacts disease recurrence. The primary aim of this study is to describe and present the authors experience with a simple, reliable, and reproducible approach to the suprahyoid area in a Sistrunk procedure. METHODS A retrospective review of the surgical management of thyroglossal duct remnants by a single surgeon at the Childrens Hospital Los Angeles over a 16-year period was performed. Demographic and clinical data including disease recurrence and other complications were collected. Recurrence rates before and after the consistent application of a modified Sistrunk procedure were compared. RESULTS 94 patients (54% female and 46% male; mean age 5.2 years) met the inclusion criteria for this study. Overall recurrence rate following a Sistrunk procedure was 2.2%; 11.1% prior to 2004 and 0% after 2004, following consistent implementation of the surgical approach to the suprahyoid region as detailed in this study. Complications were minor and mean follow-up was 5.4 months. CONCLUSIONS The author has described a simple, reproducible, and reliable approach to the suprahyoid area in a Sistrunk procedure that limits incomplete excision with minimal risk for complications. This approach to the suprahyoid region should be considered for routine use in the management of both primary and revision thyroglossal duct remnants.
