Children with complex respiratory and gastrointestinal disorders frequently require care from multiple pediatric subspecialists. Interdisciplinary pediatric aerodigestive clinic centers have been established at several pediatric tertiary care centers in the United States. Their effectiveness is unknown.
To determine whether an interdisciplinary approach to pediatric aerodigestive disorders reduces health care costs and burden.
Design, Setting, and Participants
Retrospective medical record review for the first 125 unique pediatric patients (median age, 1.51 years) seen at the Pediatric Aerodigestive Center (PAC) for aerodigestive disorders between June 2010 and August 2013 for a total of 163 outpatient clinical encounters. The PAC is an academic pediatric tertiary care center where specialists in gastroenterology, otolaryngology, pulmonology, and speech-language pathology provide interdisciplinary evaluation during a single clinic encounter and combined operative management when indicated.
Interdisciplinary evaluation and treatment of pediatric aerodigestive disorders.
Main Outcomes and Measures
Number of operative procedures and estimated hospital charges related to combining clinic encounters and operative procedures.
During the initial visit, each of the 125 patients received a mean (SD) of 2.9 (0.8) of a potential 4 services. Estimating per-encounter visit costs for gas, parking, and facility fees, we found that the average cost savings per family per PAC visit was $182. Evaluation under anesthesia was recommended for 85 patients (68%), resulting in 267 operative procedures performed by participating services during 158 encounters with general anesthesia. Thus, 109 episodes of anesthesia were avoided (41% reduction), reducing the risks of anesthesia and related care costs ($1985 per avoided episode).
Conclusions and Relevance
Coordination of interdisciplinary care in the PAC resulted in a reduction of hospital charges realized through reduction in clinic- and anesthesia-related visits. Reductions in episodes of anesthesia may also reduce neurocognitive risks associated with multiple anesthetic exposures. Other nontangible benefits associated with the coordination of care, such as caregiver satisfaction, warrant further study.
Children with complex respiratory and gastrointestinal symptoms, also known as aerodigestive disorders, can present with a variety of diagnoses, including sleep apnea, asthma, congenital airway or esophageal anomalies, dysphagia, feeding disorders, gastroesophageal reflux, esophagitis, and/or airway malacia. The burden of disease is unknown because no estimates of the prevalence of these complex aerodigestive disorders exist, but these conditions may be more common than previously realized. One common presentation of a pediatric aerodigestive disorder is infant feeding disorder: in 2010 2.6% of sick newborns discharged from short hospital stays in the United States had feeding disorders (International Classification of Diseases, Ninth Revision [ICD-9] code 779.3).1 These disorders, even as comorbidities, can lead to increased mortality and morbidity; for example, comorbid dysphagia in hospitalized patients has been associated with longer hospital stays and increased mortality.2 These children frequently require care from multiple pediatric subspecialists, including gastroenterologists, dietitians and/or nutritionists, otolaryngologists, pulmonologists, respiratory therapists, and speech-language pathologists. Over the past decade, a number of pediatric tertiary care hospitals have established interdisciplinary clinics to coordinate care,3,4 including at least 35 centers in the United States as of May 2014 (found via systematic web search for pediatric aerodigestive center websites, May 16, 2014).
The primary goal of pediatric interdisciplinary coordination of care is to improve outcomes. Benefits of interdisciplinary approaches for children have been observed in the management of obesity,5,6 asthma,7,8 diabetes,9,10 and cystic fibrosis.11,12 Compared with conventional subspecialty care where clinicians are seen on separate occasions, coordinated care of aerodigestive disorders may result in a more rapid reduction in symptoms owing to earlier diagnoses and thereby improve patient and family quality of life. In addition, although some pediatric interdisciplinary clinics have demonstrated a reduction of costs to the family and society for nonaerodigestive disorders,13-15 others have not.16 Finally, in a number of cases medical management fails to improve aerodigestive disorders,3 and examination under anesthesia may be warranted, including flexible and rigid bronchoscopy and esophagogastroduodenoscopy. An interdisciplinary approach may reduce the number of separate episodes of anesthesia and thus reduce the risks associated with anesthesia. We have been unable to locate any published studies quantifying the potential benefits of an interdisciplinary approach to pediatric aerodigestive disorders.
In 2010, the Pediatric Aerodigestive Center (PAC) was established at our pediatric tertiary care center to coordinate care by specialists in gastroenterology, otolaryngology, pulmonology, and speech-language pathology. The goals of this joint effort were to provide interdisciplinary evaluation during a single clinic encounter and combine operative management, when warranted, with the goal of reducing anesthesia exposure. The purpose of the present investigation was to determine the effect of interdisciplinary coordination on health care costs and anesthesia-related risks. We hypothesized that clinical coordination between pediatric subspecialties would lead to reduced estimated hospital charges and number of episodes of general anesthesia, with the primary assumption that all care coordinated through the PAC would have been achieved through separate clinic visits and operative encounters if the patient were not seen in PAC.
This retrospective medical record review was approved by the Johns Hopkins institutional review board, which waived written informed consent.
All participants (n = 125) attended the Johns Hopkins PAC between June 2010 and August 2013. Patients were internally referred to the PAC by pediatric subspecialty faculty at Johns Hopkins as well outside referrals from area pediatricians. There were no specific criteria for clinic attendance; but patients typically had multisystem symptoms and/or diagnoses.
Race and/or ethnicity was self-reported. Driving distance to clinic was calculated from residential zip code using Google Maps.
Dates of clinical encounters in the PAC were obtained through medical record review. A subject was defined as having seen a particular specialty service on the basis of a dictated note in the electronic medical record. Subjects had the potential to be seen by as many as 4 services on a single clinic visit, including gastroenterology, otolaryngology, pulmonology, and speech-language pathology. The PAC clinicians determined which participants needed which consulting services in a pre-clinic meeting.
Decisions to proceed with operative procedures were based on clinician judgment. Dates of operative procedures were obtained through medical record review. A participant was defined as having a procedure on the basis of a dictated note in the electronic medical record. An operative encounter for a specific service encompassed all procedures performed by that service on a single day. For example, a laryngeal cleft repair and tonsillectomy performed by otolaryngology on a single day would be tabulated as a single operative encounter for otolaryngology, although 2 separate procedures were performed. In contrast, multiple services performing procedures on the same day would be tabulated as separate operative encounters; a laryngeal cleft repair and tonsillectomy performed by otolaryngology and a flexible bronchoscopy performed by pulmonology would be tabulated as 2 separate operative encounters because 2 specialty services completed procedures.
A missed opportunity for coordination of care was arbitrarily defined as a specialty service performing an elective procedure within 90 days of a different PAC specialty service performing a procedure on the same patient after the initial PAC visit. For example, gastroenterology performing a diagnostic esophagogastroduodenoscopy 60 days after otolaryngology performed an adenoidectomy would be coded as a missed opportunity.
Publically available 2014 charge rates for our institution for preoperative and postoperative care are $11.41 per minute; for anesthesia time, $6.65 per minute; and for operating room time, $24.17 per minute (http://www.hscrc.state.md.us).
Demographic frequencies and clinical outcomes were tabulated and summarized using STATA IC 11 software (StataCorp LP). Only descriptive statistics were performed.
There were a total of 163 outpatient clinical encounters in the interdisciplinary PAC for 125 unique participants: 97 participants were seen once; 20 had 2 visits; 6 had 3 visits; and 1 had 4 visits to the PAC. Of the 125 participants, 62.4% were boys, and 65.6% were white (Table 1). The median age at the initial clinic visit was 1.51 years (age range, 0.08-21.26 years). During the initial clinic visit, participants were seen by an average (SD) of 2.9 (0.8) of 4 possible consulting services (Table 2). Specifically, 72.8% of participants were seen by gastroenterology, 96.8% by otolaryngology, 72.0% by pulmonology, and 50.4% by speech-language pathology.
Estimated costs for a trip to the clinic independent of clinician fees include facility fees ($80 per clinic visit) and parking ($10). Based on residential zip code, families resided a median of 25.3 miles from the clinic location (range, 0.60-2099.00 miles). Estimated costs for gas for a clinic round trip using median mileage for the calculations were $5.90. Thus, for every additional clinic clinician seen in the PAC at a single visit, a total of $96 was saved. In a single PAC visit, families saw a mean of 2.9 clinicians; thus, on average, 1.9 additional trips to clinic were avoided, resulting in mean savings of $182 per participant. Costs related to child care, meals, and missed time from work were not calculated.
Of the 125 participants, 85 (68%) underwent a total of 267 operative encounters by participating services in the operating room after the initial PAC visit (Table 3). This included 99 encounters with gastroenterology, 117 with otolaryngology, and 51 with pulmonology. At least 60.8% of participants had at least 1 procedure performed by otolaryngology; 55.8% had at least 1 procedure performed by gastroenterology; and 33.6% had at least 1 procedure performed by pulmonology. These 267 encounters with the participating services required a total of 158 episodes of general anesthesia. Thus, by services coordinating to combine procedures, a total of 109 episodes of anesthesia were avoided (41% reduction). Of note, only 32 participants (26%) underwent “triple endoscopy”(bronchoscopy, esophagogastroduodenoscopy, and laryngoscopy).
There were 2 occurrences of a service performing a procedure within 90 days of a different service performing a procedure. On both of these occasions, a procedure was emergently required (one for gastrostomy tube replacement, the other for pulmonary infiltrate); thus, there were no missed opportunities for coordinating elective procedures to minimize anesthesia exposure.
There are several components of charges for operative encounters, including the operating clinician’s fee, the anesthesiologist’s fee, and the facility fee. The facility fee encompasses preoperative care, operating room costs, and postoperative observation. We assume that if operative encounters are combined, the operating clinician’s fees, anesthesiologist’s fees, and operating room costs for the procedure remain similar to those if the procedures were performed separately. However, some savings may be realized from reduced anesthesia costs, reduced operating room time, and fewer episodes of preoperative and postoperative care. For each combined procedure, an estimated 2 hours of preoperative and postoperative care was avoided in addition to a reduction of 20 minutes of induction and emergence time, which is typically conducted in the operating room at our facility. Based on publically available 2014 charge rates for our institution, $1369 was saved in preoperative and postoperative charges, $133 saved in anesthesia charges, and $483 saved in operating room charges, for a total of $1985 per avoided anesthetic encounter. Thus, in avoiding 109 anesthetic encounters, participants realized an estimated $216 365 reduction in hospital charges, or an average of $3490 for each of the 62 participants who underwent combined procedures or $1731 per participant when averaged over the entire clinic population.
This is the first investigation to our knowledge to report on the potential reduction in hospital charges associated with an interdisciplinary approach for children with aerodigestive disorders. Our model of care also meets 1 of the goals (care coordination) of the Patient Protection and Affordable Care Act signed into US law in 2010. Coordination of care has been defined by the Agency for Quality Healthcare and Research (AHQR) as “the deliberate organization of patient care activities between two or more participants (including the patient) involved in a patient’s care to facilitate the appropriate delivery of health care services.”17(p41) Furthermore, organization of care can be defined as “the marshaling of personnel and other resources needed to carry out all required patient care activities and is often managed by the exchange of information among participants responsible for different aspects of care.”18(p41) We found that coordination of interdisciplinary care in the PAC resulted in a theoretical hospital charge reduction and clinic costs of nearly $2000 per participant realized through reduction in clinic- and anesthesia-related visits as well as a reduction in the number of episodes of anesthesia.
In our interdisciplinary approach to pediatric aerodigestive disorders, we estimate a savings of $182 for the initial clinic visit and $1731 per participant for operative encounters, yielding a total reduction of hospital charges and clinic costs of $1913 per participant. It is also possible that further reductions in health care burden were realized through decreased lost time from work and family responsibilities and a reduction in acute care utilization through coordination of care.
However, it should be recognized that while interdisciplinary coordination of care for children and a subsequent estimated reduction in hospital charges results in a theoretical cost savings, this assumption of cost savings may not be true for all stakeholders. For example, all clinicians and/or hospitals may not find this model financially viable. A 2004 study19 in a pediatric endocrinology practice observed that clinician expenses were covered in a single specialty clinic for diabetes but not in an interdisciplinary one. In terms of insurers’ costs, it is possible that attending an interdisciplinary aerodigestive clinic leads to more operative procedures. A 2005 study16 of 175 medically complex children enrolled in an interdisciplinary primary care clinic reported decreased lengths of stay for hospital admissions but increased use of surgical services after enrollment in the clinic. Finally, depending on the deductible amount of their insurance coverage, families may still face the same out-of-pocket expenses even with our estimated reduction of hospital costs.
We found that through coordination of care, the number of anesthesia episodes experienced by medically complex children was reduced by 41%. Such a reduction may have only marginal reduction in cumulative anesthesia duration, but it substantially reduces the number of inductions and emergences a patient experiences. This has implications for patient safety because anesthesia-related critical events may disproportionately occur during induction and emergence.20-22
In addition, recent reports have highlighted the potential association between multiple episodes of anesthesia and learning disabilities and other poor neurocognitive outcomes.23-27 However, this observed association in retrospective populations is not seen in all populations.28 In the absence of more definitive data from pending prospective studies of anesthesia and neurocognitive outcomes,29 we cannot speculate that the participants who underwent combined operative encounters had better developmental outcomes than if they had undergone the encounters separately.
Furthermore, it is unclear whether cumulative anesthesia duration or number of episodes of anesthesia is the true risk factor.30 This is a key distinction because our interdisciplinary approach may or may not have marginal reduction in cumulative anesthesia duration.
Although the present report is one of the first to describe some of the potential benefits of an interdisciplinary approach to pediatric aerodigestive disorders, our study does have limitations. The most significant limitation is our assumption that all care provided through the PAC would have occurred even if the participant had not attended the PAC. It is possible that not attending the PAC could lead to lower hospital charges because clinic visits and procedures by some subspecialists might not have occurred. However, it is also possible that not attending the PAC might have led to higher costs through poorly coordinated care.
In terms of generalizability, our patients are internally referred, and consequently our case mix, both in terms of severity of symptoms and frequency of specific diagnoses, may be different than that seen in other pediatric institutions where self-referral occurs; thus, the cost savings and anesthetic reduction may differ from other centers. Additionally, although it is possible that coordination of care leads to a reduction in acute care utilization, we were not able to capture costs related to admissions or clinic visits for acute exacerbations of the participants’ chronic aerodigestive conditions. Our institution is located in a dense urban area and not necessarily the closest institution for acute care admissions for most of our participants.
Although we observed a reduction in potential charges for medical care and a reduction in the number of episodes of anesthesia, there are certainly other nontangible benefits associated with the coordination of care that our study did not capture. Specifically, such potential benefits may include direct medical benefits of more rapid diagnoses and treatment, better communication between clinicians, decreased wait times for families to receive a coordinated plan of care, and indirect benefits such as improved caregiver satisfaction. Prospective longitudinal studies are needed to capture the benefits and improved outcomes that interdisciplinary pediatric aerodigestive clinics can potentially offer.
