Cost-effectiveness of polysomnography in the management of pediatric obstructive sleep apnea

OBJECTIVES

At our institution, younger children require polysomnography (PSG) testing to confirm obstructive sleep apnea (OSA hereafter) before surgical intervention by adenotonsillectomy (T&A). Given that sleep studies can be costly, we investigated the cost-effectiveness of PSG as well as the possible role for symptom documentation in evaluation for T&A.

METHODS

Pediatric patients age 1-3 years who received PSG testing between Jan. 2015 and Jan. 2016 who had not previously had T&A were identified for retrospective cost analysis. Cost data were obtained from institutional accountants. We defined a positive PSG as obstructive apnea-hypopnea index ≥1. Logistic regression analysis was used, and statistical significance was set a priori at p < 0.05. Sensitivities and specificities of symptom documentation screen for OSA were compared to gold standard, or PSG testing.

RESULTS

Of the 176 children who received polysomnography testing, 140 (80%) had a positive PSG indicative of OSA. Seventy-one (51%) children with OSA underwent T&A within 1 year of PSG, and 10 (7%) eventually received T&A after 1 year from PSG date. Of the children whose PSG results were negative (n = 36), 14 (39%) still underwent T&A within 1 year (n = 7, 19%) or later (n = 7, 19%). Children with positive sleep studies were significantly more likely to receive T&A within one year of PSG (p = 0.0006) and at any time after PSG (p = 0.04). Hospital costs for T&A varied widely while PSG costs were fairly consistent. Using average institutional costs of T&A and PSG, the total cost of a T&A was 17.7× the cost of PSG testing. Using number of recorded symptoms to diagnose OSA instead of PSG testing yielded low specificities.

CONCLUSION

Fifty-eight percent of patients with OSA and 39% of patients without OSA had a T&A within 1 year or later, although positive PSG was significantly associated with a higher likelihood of receiving T&A. Given costs at this institution and current decision-making practices, 147 PSGs would need to be done to account for the cost of one T&A, which in our cohort would occur after approximately 305 days.

Cost-Effectiveness Analysis of Intracapsular Tonsillectomy and Total Tonsillectomy for Pediatric Obstructive Sleep Apnea

PURPOSE

We performed an economic evaluation using a decision-tree model to analyze the relative cost effectiveness from the United States Centers for Medicare and Medicaid Services (CMS) perspective of two different methods of tonsillectomy (traditional total tonsillectomy and partial intracapsular) for pediatric obstructive sleep apnea (OSA).

MATERIALS AND METHODS

Procedural costs were drawn from published literature and Medicare values. Effectiveness and probabilities were drawn from medical literature. Primary intervention was monopolar-technique total tonsillectomy or microdebrider-assisted partial intracapsular tonsillectomy. Secondary interventions included operative control of hemorrhage, treatment of severe dehydration, or revision tonsillectomy. The decision model starts with pediatric patients with OSA, choosing between total and partial tonsillectomy. Outcomes were measured by costs (US dollars), effectiveness [quality-adjusted life year (QALY)], and a willingness-to-pay threshold of US$100,000/QALY. Base case analysis, probabilistic sensitivity analysis (PSA) and deterministic sensitivity analyses were performed. Primary outcome was incremental cost-effectiveness ratio (ICER) for each of the two tonsillectomy techniques.

RESULTS

Base case analysis demonstrated that total tonsillectomy was more cost effective at US$12,453.40 per QALY gained. In PSA, 82.84% of the simulations show total tonsillectomy to be the more cost-effective strategy. Deterministic sensitivity analyses showed that when the rate of OSA recurrence is lower than 3.12%, partial tonsillectomy would be more cost effective. When the failure rate of partial tonsillectomy is below 1.0%, it is more cost effective even when total tonsillectomy is 100% successful.

CONCLUSION

Study results suggest that overall monopolar-technique total tonsillectomy is more cost effective. However, with varying adjustments for disutility caused by procedural complications, intracapsular tonsillectomy could become a more cost-effective technique for treating pediatric OSA.

Indirect costs related to caregivers' absence from work after paediatric tonsil surgery

Tonsillotomy has gradually replaced tonsillectomy as the surgical method of choice in children with upper airway obstruction during sleep, because of less postoperative pain and a shorter recovery time. The aim of this study was to examine the costs related to caregivers' absenteeism from work after tonsillectomy (TE) and tonsillotomy (TT). All tonsillectomies and tonsillotomies in Sweden due to upper airway obstruction during 1 year, reported to the National Tonsil Surgery Register in children aged 1-11 were included, n = 4534. The number of days the child needed analgesics after surgery was used as a proxy to estimate the number of work days lost for the caregiver. Data from the Social Insurance Agency (Försäkringskassan) regarding the days the parents received temporary parental benefits in the month following surgery were also analysed. The indirect costs due to the caregivers' absenteeism after tonsillectomy vs tonsillotomy were calculated, using the human capital method. The patient-reported use of postoperative analgesic use was 77% (n = 3510). Data from the Social Insurance Agency were gathered for all 4534 children. The mean duration of analgesic treatment was 4.6 days (indirect cost of EUR 747). The mean number of days with parental benefits was 2.9 (EUR 667). The indirect cost of tonsillectomy was 61% higher than that of tonsillotomy (EUR 1010 vs EUR 629). The results show that the choice of surgical method affects the indirect costs, favouring the use of tonsillotomy over tonsillectomy for the treatment of children with SDB, due to less postoperative pain.

Cost-Effectiveness of Tonsillectomy for Recurrent Acute Tonsillitis

Objectives:

We used a retrospective case series to perform a preliminary study to determine the clinical effectiveness and cost-effectiveness of tonsillectomy for recurrent acute tonsillitis.

Methods:

We studied 25 children and 16 adults who had tonsillectomy for recurrent acute tonsillitis. The adult patients and the children's caregivers were asked to respond to a questionnaire regarding the efficacy of their tonsillectomy. The cost of medical care and the work disability cost for tonsillitis and for tonsillectomy were calculated. We then applied the technique of break-even time analysis to assess when the total health care cost savings from surgery overtook the total cost of tonsillectomy.

Results:

In children, the overall economic costs (medical costs and work-related costs) were recovered at 1.6 years after tonsillectomy (break-even point). In adults, the overall economic costs (medical costs and work-related costs) were recovered at 2.5 years after tonsillectomy (break-even point).

Conclusions:

Tonsillectomy for recurrent acute tonsillitis is both clinically effective and cost-effective for children and adults in Japan.

Electrocautery versus Cold Knife Technique Adenotonsillectomy: A Cost Analysis

OBJECTIVE: Much has been written about the merits of various techniques of adenotonsillectomy. Proponents of each technique tout many virtues over one another. However, cost remains one variable that has not been thoroughly addressed. In this study, we compared the surgery time, anesthesia time, bleeding, and cost between 2 well-established techniques. Electrocautery tonsillectomy/adenoid ablation was compared against traditional cold knife dissection with adenoid curette.

STUDY DESIGN AND SETTING: A retrospective chart review of 275 patients in a large tertiary teaching hospital.

RESULTS: The electrocautery group had overall savings of 8, 8, and 9 minutes in surgery, anesthesia, and operating room times, respectively. In terms of cost, the variable cost of the electrocautery group was 19% less than the cold knife dissection group.

CONCLUSION/SIGNIFICANCE: This study demonstrated that cautery ablation of adenoids, when employed as part of adenotonsillectomy, enables the surgical team to save significant amount of time, and substantial cost for patients. EBM rating: B-3.

Causes, costs, and risk factors for unplanned return visits after adenotonsillectomy in children

OBJECTIVE

To review the causes, costs, and risk factors for unplanned return visits and readmissions after pediatric adenotonsillectomy (T&A).

METHODS

Review of administrative database of outpatient adenotonsillectomy performed at any facility within a vertically integrated health care system in the Intermountain West on children age 1-18 years old between 1998 and 2012. Data reviewed included demographic variables, diagnosis associated with return visit and costs associated with return visits.

RESULTS

Data from 39,906 children aged 1-18 years old were reviewed. A total of 2499 (6.3%) children had unplanned return visits. The most common reasons for return visits were bleeding (2.3%), dehydration, (2.3%) and throat pain (1.2%). After multivariate analysis, the main risk factors for any type of return visits were Medicaid insurance (OR=1.64 95% CI 1.47-1.84), Hispanic race (OR=1.36 95% CI 1.13-1.64), and increased severity of illness (SOI) (OR=11.29 95% CI 2.69-47.4 for SOI=3). The only factor associated with increased odds of requiring an inpatient admission on return visit was length of time spent in PACU (p<0.001). A linear relationship was also observed between the child's age and the risk of post-tonsillectomy hemorrhage.

CONCLUSION

Children with increased severity of illness, those insured with Medicaid, and children of Hispanic ethnicity should be targeted with increased education and interventions in order to reduce unplanned visits after T&A. Further studies on post-tonsillectomy complications should include evaluating the effect of surgical technique and post-operative pain management on all complications and not solely post-tonsillectomy hemorrhage.

The NAtional randomised controlled Trial of Tonsillectomy IN Adults (NATTINA): a clinical and cost-effectiveness study: study protocol for a randomised control trial

BACKGROUND

The role of tonsillectomy in the management of adult tonsillitis remains uncertain and UK regional variation in tonsillectomy rates persists. Patients, doctors and health policy makers wish to know the costs and benefits of tonsillectomy against conservative management and whether therapy can be better targeted to maximise benefits and minimise risks of surgery, hence maximising cost-effective use of resources. NATTINA incorporates the first attempt to map current NHS referral criteria against other metrics of tonsil disease severity.

METHODS/DESIGN

A UK multi-centre, randomised, controlled trial for adults with recurrent tonsillitis to compare the clinical and cost-effectiveness of tonsillectomy versus conservative management. An initial feasibility study comprises qualitative interviews to investigate the practicality of the protocol, including willingness to randomise and be randomised. Approximately 20 otolaryngology staff, 10 GPs and 15 ENT patients will be recruited over 5 months in all 9 proposed main trial participating sites. A 6-month internal pilot will then recruit 72 patients across 6 of the 9 sites. Participants will be adults with recurrent acute tonsillitis referred by a GP to secondary care. Randomisation between tonsillectomy and conservative management will be according to a blocked allocation method in a 1:1 ratio stratified by centre and baseline disease severity. If the pilot is successful, the main trial will recruit a further 528 patients over 18 months in all 9 participating sites. All participants will be followed up for a total of 24 months, throughout which both primary and secondary outcome data will be collected. The primary outcome is the number of sore throat days experienced over the 24-month follow-up. The pilot and main trials include an embedded qualitative process evaluation.

DISCUSSION

NATTINA is designed to evaluate the relative effectiveness and efficiency of tonsillectomy versus conservative management in patients with recurrent sore throat who are eligible for surgery. Most adult tonsil disease and surgery has an impact on economically active age groups, with individual and societal costs through loss of earnings and productivity. Avoidance of unnecessary operations and prioritisation of those individuals likely to gain most from tonsillectomy would reduce costs to the NHS and society.

Impact of tonsillectomy on health-related quality of life and healthcare costs in children and adolescents

BACKGROUND

Tonsillectomy is a common surgical intervention in children, but its efficacy is under debate. We studied whether tonsillectomy is a cost-effective intervention with a positive impact on health-related quality of life (HRQoL).

METHODS

Children (aged 7-11 years) and adolescents (aged 12-15 years) undergoing tonsillectomy answered the 17D or 16D HRQoL questionnaires before tonsillectomy and at 6 and 12 months postoperatively. At the same time-points, data on the use of healthcare services and school absenteeism were collected by questionnaire.

RESULTS

Altogether 49 children and 42 adolescents returned all HRQoL questionnaires. Tonsillectomy improved the mean total HRQoL score clinically and statistically significantly in both children (from 0.935 at baseline to 0.958 at 12 months, p = 0.002) and adolescents (from 0.930 to 0.957, p = 0.004). The mean direct self-reported healthcare service costs diminished after tonsillectomy in both groups. The mean number of days on sick leave due to oropharyngeal problems during the preceding 3 months decreased from the preoperative 4.6 days to postoperative 0.5 days (p < 0.001) in children, and from 4.9 days to 0.8 days (p < 0.001) in adolescents at 12 months.

CONCLUSIONS

Tonsillectomy improves HRQoL in both school-aged children and adolescents and reduces healthcare service needs and school absenteeism due to oropharyngeal symptoms.

Effect of tonsillectomy on health-related quality of life and costs

CONCLUSION

Tonsillectomy (TE) seems to be a cost-saving procedure with a positive effect on a patient's health-related quality of life (HRQoL).

OBJECTIVES

The aim of this study was to explore how TE affects health-related quality of life (HRQoL) and the costs due to health service use and absence from work.

METHODS

All 557 patients over the age of 15 years undergoing scheduled TE in the Helsinki University Central Hospital's Otorhinolaryngological Department between February 2008 and June 2009 were asked to participate and to complete the 15D HRQoL questionnaire as well as a questionnaire exploring the use of health-care services during the preceding 3 months. Follow-up questionnaires were sent 6 and 12 months after the operation.

RESULTS

Of the 557 patients, 124 (22%) answered all three questionnaires. Preoperatively the patients were significantly worse off than the age- and gender-standardized general population. TE improved their HRQoL on 6 of the 15 dimensions, and overall (15D score improved from baseline 0.939 to 0.959 at 12 months, p < 0.001). The most marked improvement (p < 0.001) occurred on the dimensions of breathing, sleeping, and discomfort and symptoms. Self-reported costs due to health service use and absence from work distinctly diminished.

Tonsillectomy compared to acute tonsillitis in children: a comparison study of societal costs

INTRODUCTION AND AIM

Tonsillectomy is one of the most commonly performed surgical procedures in children; its main indications are recurrent episodes of acute tonsillitis and adenotonsillar hypertrophy. The effectiveness of tonsillectomy for severe recurrent tonsillitis is generally accepted; however its socio-economic cost is less well investigated. This study aims to determine and compare the societal cost of a tonsillectomy and a severe throat infection.

MATERIALS AND METHODS

The costs for both tonsillectomy and severe throat infection were evaluated. Costs of the surgical procedure and hospital stay were calculated based on resource use and personnel input at the participating hospital. The cost of work-related disability for both treatments was measured based on a questionnaire filled in by 275 parents of children undergoing a tonsillectomy. Data from two Belgian institutions (NIS and FOD) were used to calculate the cost of parents' absenteeism.

RESULTS

An episode of acute tonsillitis in the child results in a longer period of parents' work absenteeism (mean of 3.1 +/- 0.3 days) compared to tonsillectomy (2.2 +/- 0.2 days). The cost of economic productivity loss amounts to 613 Euros (NIS) or 759 Euros (FOD) for acute tonsillitis and 435 Euros (NIS) or 539 Euros (FOD) for a tonsillectomy. The medical costs linked to the surgical procedure at the local department correspond to 535 Euros and for an acute tonsillitis to 46 Euros.

CONCLUSIONS

From societal perspective, a tonsillectomy costs the equivalent of 1.4 times the cost of a severe throat infection. This indicates that in children suffering from recurrent acute tonsillitis, watchful waiting results in a higher cost compared to tonsillectomy, given the cumulative costs of parents' absenteeism.

Recurrent tonsillitis in adults: quality of life after tonsillectomy

BACKGROUND

The aim of this study was to assess the effect of tonsillectomy in adults with recurrent tonsillitis on their quality of life and on their use of medical resources.

METHOD

114 patients who had had at least three episodes of acute tonsillitis in the 12 months preceding tonsillectomy were evaluated pre- and postoperatively with a questionnaire developed by the authors, and with the Glasgow Benefit Inventory.

RESULTS

97 patients (85%) filled out the questionnaires completely. The Glasgow Benefit Inventory revealed an improvement in the overall score (+19) and in the partial scores for general well-being (+18) and physical health (+39). The degree of support from friends and family was unchanged (±0). Significant decreases were observed in visits to a physician, analgesic and antibiotic consumption, days off from work, and episodes of sore throat. The number of visits to a physician because of sore throat decreased from an average of five preoperatively to one postoperatively; the number of episodes of sore throat, from seven to two; and the number of days taken off from work, from twelve to one per year. 65% of the patients surveyed took analgesics for sore throat preoperatively, 7% postoperatively. 95% took antibiotics for sore throat preoperatively, 22% postoperatively.

CONCLUSION

Although this study had a number of limitations (small size, retrospective design, short follow-up), it was able to show that tonsillectomy for adults with recurrent tonsillitis improves health and quality of life and reduces the need to consume medical resources.

Does the added benefit of ondansetron over dexamethasone, to control post-operative nausea and vomiting, justify the added cost in patients undergoing tonsillectomy and adenotonsillectomy?

OBJECTIVE

To investigate comparative effectiveness of ondansteron and dexamethasone in prophylaxis of PONV in tonsillectomy and adenotonsillectomy patients.

METHODS

The study was conducted at Shifa International Hospital Islamabad from 1st January to 30th June 2009, on 60 patients undergoing tonsillectomy or adenotonsillectomy, with their consent. After consecutive alternate sampling, patients were divided into two groups containing 30 patients each. Ondansteron was given in one group, and Dexamethasone in the other group, as anti emetic, at the time of induction. Episodes of PONV were recorded at three specified intervals, i.e., immediate postoperative, 6 hours after surgery and 12 hours after surgery. Data was entered on a pre-designed performa. The data was analyzed in SPSS Version 13.0.

RESULTS

Ondansteron Group had a mean age of 12.7 +/- 9.54 years (5-36 years). There were 22 (73.3%) males and 8 (26.7%) females. Dexamethasone Group had a mean age of 14.8 +/- 8.4 years (5-35 years) of whom 18 (60.0%) were males and 12 (40.0%) were females. Overall 6 patients who received ondansetron had PONV compared to 7 patients in the dexamethasone group. This difference was statistically insignificant (p > 0.05).

CONCLUSION

Dexamethasone was equally effective in controlling PONV in tonsillectomy and adenotonsillectomy patients. The improved benefit of using ondansetron over dexamethasone, on a regular basis, does not justify the added cost.

Is routine pathological examination required in South African children undergoing adenotonsillectomy?

OBJECTIVE

We aimed to determine the incidence of abnormal pathological findings in the tonsils and/or adenoids of children undergoing tonsillectomy and/or adenoidectomy, and the incidence of tuberculosis of the tonsils and adenoids; suggest criteria to identify children at risk for adenotonsillar tuberculosis; and investigate the association between HIV and adenotonsillar abnormality, the cost-effectiveness of routine pathological examination of adenotonsillectomy specimens, and criteria to decide which specimens to send for histological examination.

METHODS

We undertook an 8-month prospective study on all children (< or =12 years) undergoing consecutive tonsillectomy or adenotonsillectomy (T&A) at Red Cross War Memorial Children's Hospital. Patients were assessed pre-operatively and tonsil sizes graded pre- and intra-operatively. Blood was taken for HIV testing, and all tonsils and adenoids were examined histologically. A cost-benefit analysis was done to determine the cost-effectiveness of adenotonsillectomy routine pathology.

RESULTS

A total of 344 tonsils were analysed from 172 children (102 boys, 70 girls); 1 patient had nasopharyngeal tuberculosis, and 1 lymphoma of the tonsils; 13 (7.6%) patients had clinically asymmetrically enlarged tonsils but no significant abnormal pathological finding. The average cost of detecting a clinically significant abnormality was R22 744 (R45 488 + 2 abnormalities).

CONCLUSIONS

The following criteria could improve cost-effectiveness of pathological examination of adenotonsillectomy specimens: positive tuberculosis contact at home, systemic symptoms of fever and weight loss, cervical lymphadenopathy >3 cm, suspicious nasopharyngeal appearance, HIV-positive patient, rapid tonsillar enlargement or significant tonsillar asymmetry. On our evidence, routine pathological investigation for South African children does not seem to be justified.

Health care reform: pediatric elective surgery payer mix and utilization under Tenncare managed competition

Managed care decreases reimbursement for surgical referral care and may decrease access for elective procedures. This study seeks to determine the impact of Medicaid managed competition on elective pediatric otolaryngology surgery.

DESIGN AND SETTING

Payer mix was analyzed for tonsillectomy and adenoidectomy (T&A) and bilateral myringotomy with ventilation tube insertion (BM&VT) charges for an eight-year period surrounding TennCare implementation. The payer mix for hospital gross charges was analyzed for the same period as a control.

RESULTS

After TennCare implementation, hospital gross charges shifted toward increased TennCare/Medicaid and decreased commercial insurance, whereas charges for the two elective procedures shifted toward increased commercial insurance and decreased TennCare/Medicaid.

CONCLUSION

Otolaryngologists avoided impending losses under TennCare through indirect cost shifting. Numbers of T&A and BM&VT procedures performed on Tenncare/Medicaid patients remained constant, while numbers of these procedures performed on commercially-insured patients increased.

Does high BMI influence hospital charges in children undergoing adenotonsillectomy?

BACKGROUND

Obesity is a highly prevalent chronic problem with health and fiscal consequences. Data from adults and nonsurgical pediatric patients suggest that obesity has serious implications for the US economy.

OBJECTIVE

Our goal was to describe the impact of BMI on hospital charges in children undergoing adenotonsillectomy (AT).

METHODS AND PROCEDURES

We carried out a retrospective comparative analysis of the electronic anesthesia record and the charges from billing data from a large tertiary institution on children aged 3-18 years who had AT during the year 2005-2007. The main outcome measures were mean total hospital charges, likelihood of admission, and length of hospital stay (LOS).

RESULTS

Of 1,643 children, 68.9% were aged <10 years, 76% were whites, and 74.1% had private commercial insurance. Most (75.3%) children were discharged on the day of surgery. Obese and overweight children were more likely to be admitted than their normal-weight peers (X(2)=26.3, P<0.001). Among those admitted, BMI showed a positive correlation with LOS (r=0.20, P<0.001). Obese and overweight patients had significantly higher total hospital charges than their healthy-weight counterparts (P=0.001). Anesthesia, postanesthesia care unit (PACU), and pharmacy and laboratory charges were also higher for obese than normal-weight children (P<0.05).

DISCUSSION

Overweight and obese children undergoing AT accrued higher hospital charges and had longer postoperative LOS than their healthy-weight peers. If these findings are extendable to other surgical procedures, they could have far-reaching implications for the US economy.

Routine histologic examination is unnecessary for tonsillectomy or adenoidectomy

OBJECTIVE

To determine whether the current practice and incurred cost of histologic examination of tonsillectomy and adenoidectomy specimens is warranted.

STUDY DESIGN

Review article based on medical literature.

SUBJECTS AND METHODS

A retrospective PubMed review of all pertinent literature regarding tonsillectomy, adenoidectomy, and related surgical pathology was conducted. References of the articles obtained were reviewed for additional sources.

RESULTS

Twenty studies report 54,901 patients and found 54 malignancies (0.087% prevalence). Of these, 48 (88% of the patients) had suspicious features such as tonsillar asymmetry, cervical lymphadenopathy, or abnormal tonsil appearance, preoperatively. The remaining six patients without any suspicious features (better representing true occult malignancy) were 0.011% of the total cases.

CONCLUSION

Submission of tonsillectomy, adenoidectomy, or both specimens is warranted only when patients demonstrate findings associated with malignancy: tonsillar asymmetry, history of cancer, neck mass, tonsil firmness or lesion, weight loss, and constitutional symptoms.

Evaluation of the utility of histopathologic exam as a routine in tonsillectomies

Tonsillectomy is one of the most commonly performed procedures of the head and neck. It is performed for a wide variety of indications in both adults and children. It is common to send the material achieved in the surgery to routine histopathologic exam, as to analyze suspected material or for a medical-legal documentation. Objective: Analyze the utility and cost of routine histopathologic diagnosis for tonsillectomy. Methodology: retrospective study of the histopathologic result of all tonsillectomies between 1978 and 2004 in a university hospital and analyzed the files of the patients with cancer. Results: 2103 results of histopathologic exams were analyzed. Of these, only four cases presented any case of malignancy, being all of these non-Hodgkin lymphoma and already suspected before the surgery. Discussion: The world literature has encountered similar results and each time more the histopathologic analysis of all cases is questioned. The cost of the exam is high and your results, in the case of malignancy were already knew before the surgery. Conclusion: Histopathologic analysis of all tonsillectomies is not indicated. The risks factors established by Beaty should guide the solicitation of the exam, to try to low the costs with unnecessary exams.

Outcomes of reduced postoperative stay following outpatient pediatric tonsillectomy

OBJECTIVE

To assess outcomes of reduced postoperative recovery room observation times and associated complication rates following outpatient pediatric adenotonsillectomy at a tertiary care medical center outpatient facility over a 7.5-year period.

STUDY DESIGN

Retrospective chart review.

METHODS

Charts from all outpatient pediatric adenotonsillectomies performed by one surgeon from January 1998 through June 2005 at a tertiary care center were reviewed.

RESULTS

Seven hundred and ninety seven (797) charts had sufficient documentation to be included in this study. Mean patient age was 6.8 years (median 5.5 years, range 2-21 years). There were 53 patients under 3 years old (6.64%), 655 patients age 3-12 years (82.18%), and 89 patients age 12-21 years (11.17%). Mean postoperative recovery room observation time prior to discharge was 1.47 h (median 1.33 h, range 0.45-7.25 h). Primary (<24 h postoperative) complication rate was 0.0075%, and secondary (>24 h postoperative) complication rate was 0.0063%. There were no significant differences in duration of postoperative recovery room observation or postoperative complications between the three age groups (p=0.10).

CONCLUSIONS

Very brief postoperative observation periods following outpatient pediatric adenotonsillectomy may be considered safe, without added risk nor increased short-term or long-term complications. While individual cases may merit prolonged postoperative observation periods, the majority of study patients had no postoperative complications despite shorter recovery room stays than described in prior reports. These data support safety and efficacy of reduced postoperative stays. Our data should be considered in order to increase the efficiency and cost effectiveness of outpatient surgery centers where such procedures are performed.

Meta-analysis of the timing of haemorrhage after tonsillectomy: an important factor in determining the safety of performing tonsillectomy as a day case procedure

OBJECTIVES

To perform a meta-analysis of studies of the timing of primary tonsillectomy haemorrhage. In particular to compare the difference in risk between 0-8 and 8-24 h; that is whether overnight inpatient tonsillectomy is required.

DESIGN

Medline search of all tonsillectomy studies to perform a meta-analysis of the timing of primary haemorrhages.

SETTING

Literature-based study.

PARTICIPANTS

All adult and paediatric tonsillectomy studies giving the absolute number and timing of all primary haemorrhages.

MAIN OUTCOME MEASURES

The overall incidence of haemorrhage occurring between 0-8 and 8-24 h. The overall incidence of haemorrhage for each of the first 24 h after operation. Compare risk of a bleed occurring 0-8, 8-24 and >24 h where data were available.

RESULTS

From a 1.4% overall risk of a primary haemorrhage only one in 14 occur after 8 h, i.e. 0.1% (95% CI=0.08-0.16%). A total of 833 patients would require to be kept overnight in order to identify one case of bleeding after 8 h.

CONCLUSIONS

Little benefit was conferred from overnight admission from the point of view of monitoring for primary haemorrhage. A case can be made for either day-case tonsillectomy (hospital stay over the period in which 93% of primary haemorrhages would occur) or the 'belt-and-braces' approach of a 1-week stay (during which all haemorrhages would occur) but current 24-h admission appears illogical.

Harmonic scalpel tonsillectomy versus hot electrocautery and cold dissection: an objective comparison

We conducted a large-scale retrospective study to compare the surgical efficacy, practical utility, safety, and costeffectiveness of ultrasonic harmonic scalpel tonsillectomy, hot electrocautery, and cold surgical dissection. We based our findings on the length of operating time, complication rates, the length of hospital stay for patients with complications, and relative costs. We then compared our findings with those published in earlier reports, none of which were based on a three-way comparison. Our study population was made up of 316 patients--175 males and 141 females aged 1 to 23 years (mean: 7.3)--who had undergone adenotonsillectomy or tonsillectomy alone at our tertiary care children's hospital between Sept. 1, 2000, and Aug. 31, 2001. The harmonic scalpel was used on 75 patients (23.7%), electrocautery on 109 patients (34.5%), and cold surgical dissection on 132 (41.8%). The mean length of operating time for adenotonsillectomy was 42.4 (n = 70), 43.0 (n = 103), and 49.2 (n = 95) minutes, respectively; the corresponding times for tonsillectomy alone were 23.6 (n = 5), 30.2 (n = 6), and 35.3 (n = 37) minutes. Overall complication rates were 2.7, 5.5, and 6.1%, respectively. Hospital stays for immediate (<24 hr) postoperative bleeding averaged 2.0, 1.0, and 0.7 days, respectively, and stays for dehydration averaged 1.0, 1.3, and 1.5 days. Mean per-patient institutional costs were 460.00 dollars, 310.75 dollars, and 300.00 dollars, respectively. We conclude that harmonic scalpel tonsillectomy is efficacious, practical, safe, and cost-effective, and we recommend that any institution involved with a significant number of pediatric tonsillectomies consider using it.

Adenotonsillectomy in children with obstructive sleep apnea syndrome reduces health care utilization

OBJECTIVE

To investigate health care utilization of children with obstructive sleep apnea syndrome (OSAS) 1 year after adenotonsillectomy (T&A).

METHODS

A longitudinal, case-controlled, prospective study was conducted at Clalit Health Care Services (CHS), a health maintenance organization in the southern region of Israel. We defined 3 groups of children: 1) children who had OSAS and were treated with T&A (n = 130); 2) children who had OSAS and did not undergo surgery (n = 90); and 3) control subjects who were matched by age, sex, and area of residency (n = 520) and randomly selected from the CHS database. OSAS was verified with polysomnography studies in all patients. Indices of health care utilization were analyzed 1 year before and 1 year after T&A. Medical records in the emergency department and during hospitalization were reviewed for diagnosis before the polysomnography diagnosis.

RESULTS

Mean age of all children with OSAS was 5.6 +/- 3.6 years. Total annual health care costs were reduced by one third in children who underwent T&A, whereas there was no change in the control and untreated OSAS groups. T&A was associated with a 60% reduction in the number of new admissions, 39% reduction in emergency department visits, 47% reduction in the number of consultations, and 22% reduction in costs for prescribed drugs. In group 2, the total costs were similar in years 1 and 2.

CONCLUSIONS

T&A significantly reduces health care utilization in children with OSAS. Untreated children with moderate and severe OSAS will continue to consume high levels of health care resources. Increased morbidity among children with OSAS is mainly related to upper respiratory tract infections.

Economic benefit of tonsillectomy in adults with chronic tonsillitis

To determine the economic impact of adult chronic tonsillitis and the economic improvement from adult tonsillectomy, we studied patients who underwent adult tonsillectomy for chronic tonsillitis with the Glasgow Benefit Inventory and a questionnaire for disease severity parameters before and after tonsillectomy. The economic impact of chronic tonsillitis and adult tonsillectomy were computed with a break-even time analysis model. Eighty-three adult patients (average age, 27.3 years) completed the study with an average duration of follow-up of 37.7 months. The patients exhibited a mean improvement in quality of life of +27.54 +/- 4.63 after tonsillectomy according to the Glasgow Benefit Inventory. In the 12 months following the procedure, tonsillectomy resulted in yearly mean decreases in number of weeks on antibiotics by 5.9 weeks, number of workdays missed because of tonsillitis by 8.7 days, and physician visits for tonsillitis by 5.3 visits. In considering the medical costs of tonsillectomy only, the break-even point was found to be 12.7 years, whereas considering the overall economic impact of tonsillectomy resulted in a break-even point of 2.3 years after the procedure. We conclude that tonsillectomy results in significant improvement in quality of life, decreases health-care utilization, and diminishes the economic burden of chronic tonsillitis in the adult patient population.

Evaluation of the utility and cost-effectiveness of obtaining histopathologic diagnosis on all routine tonsillectomy specimens

OBJECTIVES

To evaluate the use and necessity of obtaining histopathology on patients undergoing tonsillectomy, and to provide indications and guidelines for requesting histopathology on tonsillectomy patients.

STUDY DESIGN

At the University of Mississippi Medical Center, we have been routinely obtaining histopathologic diagnoses on every patient undergoing tonsillectomy or tonsillectomy and adenoidectomy. Specimens are separated into left and right tonsils and adenoids. This study was designed at our tertiary care academic center to evaluate the necessity for obtaining histopathologic diagnosis on each of these patients.

METHODS

A retrospective review of histopathologic reports on all patients in both pediatric and adult age groups undergoing tonsillectomy or tonsillectomy and adenoidectomy between January 1994 and December 1999 was performed.

RESULTS

A total of 2438 reports were reviewed. There were 2099 in the pediatric age group and 339 were adults. None of the children had an unusual histopathology finding other than lymphoid hyperplasia. Of the 339 adults, 34 had squamous cell carcinoma and 6 had lymphoma; however, these findings were suspected preoperatively by history and clinical manifestations.

CONCLUSIONS

The general practice guidelines mandate obtaining histopathologic diagnoses on most of the tissues received. Based on our review, histopathology of tonsillectomy and/or adenoidectomy may not be necessary, especially in children. In this era of cutting excess costs of health care dollars, waving histopathology in these cases may have major implications without compromising delivery of quality care.

[Socioeconomic aspects in the therapy of peritonsillar absscess]

OBJECTIVE

To determine which treatment for quinsy is the most cost-effective option.

MATERIAL AND METHOD

277 quinsies were diagnosed in 262 patients in our institution between 1.1.1991 and 31.12.1998. Median age was 29 years (1-89 years), and sex ratio was 3 males:2 females. 82 quinsy tonsillectomies (AC), 91 drainages with interval tonsillectomy (DAF) and 104 drainages of the abscess without tonsillectomy (D) were carried out.

RESULTS

Median hospital stay was 3 (1-7) days for quinsy tonsillectomy, and 10 (4-18) days for drainages with interval tonsillectomy (hospital stay after drainage added to hospital stay after tonsillectomy). If interval tonsillectomy is performed as an outpatient procedure, median hospital stay decreases to 5 (2-8) days. For patients who refused tonsillectomy, median hospital stay was 3 (0-14) days. Median disability after treatment was 15 (7-30) days for quinsy tonsillectomy. For drainages with interval tonsillectomy (disability succeeding the drainage added to that following interval tonsillectomy), the median is 20 (15-52) days. For patients who refused tonsillectomy it is 6 (0-15) days. In the AC group we counted 9 late haemorrhages (11%). In the DAF group 14 patients (15%) presented a late haemorrhage; 6 patients (6%) presented a postoperative superinfection of the tonsillar fossae.

DISCUSSION

On the basis of the tariffs of our institution (CHUV), and of statistical data obtained from the National Institute for Social Insurance (SUVA) with regard to the economic impact of each day of disability, the cost of the various treatment options is presented.

CONCLUSION

It results from our study that in the absence of a significant difference in the rate of complications, and even considering the possibility of carrying out interval amygdalectomy on an outpatient basis, the most cost-effective treatment of peritonsillar abscess is quinsy tonsillectomy.

Mivacurium or vecuronium for paediatric ENT surgery. Clinical experience and cost analysis

BACKGROUND

The present study compared the quality of neuromuscular block and costs after equipotent doses of mivacurium and vecuronium in the context of paediatric ENT surgery.

METHODS

A total of 30 children undergoing elective tonsillectomy were included and randomised in two groups (n = 15 for each) according to the neuromuscular blocking agent (NMBA) used. Anaesthesia was induced with alfentanil (15 micrograms/kg), propofol (3 mg/kg) and either 0.2 mg/kg mivacurium or 0.14 mg/kg vecuronium. For maintenance of anaesthesia propofol (8-12 mg/kg/h) was given. Neuromuscular block was assessed by electromyography using train-of four stimulation and the following parameters were quantified: Twitch height (T1) 2 min after the initial bolus of the myorelaxant; duration until recovery to 10% T1, number and duration of bolus injections of the myorelaxant needed to maintain neuromuscular block to a T1 < 10%. In addition, the intubating conditions, number of patients needing pharmacological reversal at the end of surgery, adverse reactions and the costs for neuromuscular block and pharmacological antagonization were assessed.

RESULTS

Intubation conditions were comparable between both study groups: mivacurium--excellent: 7, good: 5, not acceptable: 1; vecuronium--excellent: 11, good: 4 (n.s.). T1 at 2 min was 16 (15)% for mivacurium and 6 (9)% for vecuronium (P < 0.05). Time to 10% T1 recovery was 6.1 (1.7) min for mivacurium and 21.8 (3.7) min for vecuronium (P < 0.01). In the mivacurium group 7 repetitive doses (range: 4-18) were needed to maintain T1 < 10% during surgery, whereas children treated with vecuronium needed only 1 maintenance dose (range: 0-2) (P < 0.01). Two children in the mivacurium group and 11 in the vecuronium group required pharmacological reversal of the NMB at the end of surgery (P < 0.01). The overall costs of NMB were significantly higher in the mivacurium group as compared to vecuronium 12.88 (4.5) Euro vs 9.96 (2.4) Euro; P < 0.05.

CONCLUSIONS

In conclusion, mivacurium-induced NMB is of very short duration in paediatric patients, and therefore repetitive doses are required to maintain a deep neuromuscular block. Nevertheless, residual paralysis is less frequent after mivacurium. The neuromuscular block after mivacurium was more expensive and residual paralysis less frequent compared to vecuronium.

Is paediatric day case tonsillectomy desirable? The parents' perspective

Tonsillectomy is the most commonly performed otolaryngological procedure in most units. There is considerable financial pressure to perform paediatric tonsillectomy as a day case. Responding to concern that day case tonsillectomy might not be welcomed by parents or felt to be in the best interests of the patients, we carried out an audit of paediatric tonsillectomy, by means of a questionnaire for parents and nursing staff to complete while 32 consecutive patients underwent tonsillectomy as inpatients. Although eight parents (25%) felt that day surgery should be an option, none of those surveyed felt that on this occasion their child was well enough to be discharged home six hours postoperatively. Furthermore, no child in the audit fulfilled all the essential discharge criteria at six hours. In this area, at least, it appears parents do not uniformly welcome paediatric day case tonsillectomy.

[Cost effective and quality assured (adeno)tonsillectomy in children]

BACKGROUND

The issues of whether minor surgery should be performed in private or public clinics and/or be funded by the national health service are under continuous debate in Norway.

MATERIAL AND METHODS

A prospective study of the benefit of (adeno)tonsillectomies in 120 children is presented. Surgery included in the study was performed on an inpatient as well as an outpatient basis and in public as well as private clinics.

RESULTS

There was no difference in patient satisfaction or in the quality of surgery depending on the type of organisation. Relief of symptoms associated with (adeno)tonsillar infections and obstruction following surgery was consistent. Less euresis was found in the study population following surgery. Increased haemoglobin concentration and less protoporfyrin IX in erythrocytes indicate an improved erythropoiesis following (adeno)tonsillectomy. Less manpower was needed to perform (adeno)tonsillectomies in private compared to public clinics.

INTERPRETATION

We suggest that the Norwegian national health system opens up for funding surgery of established quality irrespective of whether it is performed in a public or a private clinic.

Adenotonsillectomy in the very young patient: cost analysis of two methods of postoperative care

Postoperative management of the patient younger than 36 months undergoing adenotonsillectomy has been the subject of many debates. Concerns for early postoperative complications such as airway obstruction, emesis, dehydration, and hemorrhage have led many physicians to consider overnight hospitalization following adenotonsillectomy in very young children. Trends in health care management have had increasing focus on cost effective means of treating patients to limit unnecessary expenditure on the part of the patient, physician, and hospital facility. The purpose of this retrospective review was to analyze two methods of early postoperative management in children less than 36 months old undergoing adenotonsillectomy at the Children's Hospital, San Diego from 1992 to 1997. Three hundred and seven cases were reviewed. Same-day discharge was compared with overnight inpatient observation based on the cost analysis of these two methods of postoperative care. Postoperative care was based on length of stay in the recovery room and as an inpatient. Expense of postoperative care was based on cost calculation for the recovery room and overnight hospitalization. Of the 307 patients, 194 went home the day of surgery and 113 were observed overnight in the hospital. Average hospital cost was higher in the outpatient group than in the inpatient group (P < 0.001). This difference reflects longer recovery room stay (350 min) in the outpatient group compared to the inpatient group (108 min) (P < 0.001). Outpatient adenotonsillectomy in the patient under 36 months may be safe; however, prolonged recovery room stays may actually make outpatient surgery less cost-effective than overnight admission. Recovery room costs are significantly higher per unit time than costs of inpatient hospitalization. Further investigation of cost-effective outpatient observation units may improve cost containment in the outpatient surgical setting.

[Pediatric tonsillectomy can be performed as day surgery]

In the spring of 1996, tonsillectomy, traditionally regarded as a procedure requiring hospitalization, began to be performed at the recently started day surgery unit at Danderyd Hospital. The article consists in a report of results obtained with a series comprising just over 200 children who were the first to undergo adenotonsillectomy in day surgery, and followed up, for instance, by questionnaire. There were no cases of complications requiring hospitalization during the first postoperative day. The parents were fairly satisfied with the care provided, though 25 per cent of them said that in the event of a new operation being necessary they would prefer that it be performed as an in-patient procedure.

Microscopic examination of routine tonsillectomy specimens: is it necessary?

Controversy continues to exist regarding the routine histologic examining of tonsillectomy specimens. Proponents suggest that among other reasons, missing an important diagnosis such as occult malignancy or granulomatous disease and possible medicolegal consequences argue in favor of routine histologic examination. Others state that we should consider the very low yield of significant histologic findings in routine tonsillectomy specimens and its added cost. We performed a retrospective evaluation of all cases of patients who underwent tonsillectomy with or without adenoidectomy between January 1992 and July 1996. Two hundred eighty-eight charts were evaluable. Group 1 consisted of all tonsillectomy specimens that were subjected to gross examination only. Group 2 consisted of all tonsillectomy specimens that were subjected to gross examination as well as microscopic examination. In group 1, no abnormal gross findings were noted. Group 2 consisted of specimens from an older population with a mean age of 21.6 years. There were 43 patients older than 20 years old in group 2, and in all cases except four the preoperative clinical impression correlated with the microscopic findings. Occult malignancy was found in only one of these four patients. No cases of granulomatous disease were discovered. Overall, no patients except one had any change in postoperative treatment on the basis of the results of microscopic examination. We believe that routine microscopic examination of tonsillectomy specimens results in unnecessary cost and consumption of resources and time. Microscopic examination should be done in only selected cases such as in patients with grossly asymmetric tonsils or in patients with a history of malignancy.

[No "unnecessary" care when measured by American standards. The Oregon list tested at a department of otorhinolaryngology in Halmstad]

It is often asserted in the health care debate that stricter priority setting would be one way of solving some of the economic problems. However, comparison of the workload at a Swedish ENT department with the Oregon list, one of the strictest prioritisation instruments yet devised, suggests that this is not the case. After adaptation of the Oregon list to the norms of Swedish practice (e.g., current policy regarding tonsillectomy, as elicited from Scandinavian studies), very little of the remaining workload would not be approved according to the Oregon list. Thus the scope for economy would appear to derive from professional skill in the internal planning of diagnostic investigation and treatment, rather than from the application of prioritisation systems devised by others.

Adult tonsillectomy: what proportion would accept same day discharge?

Day case surgery is increasing to improve health care cost efficiency. The economic benefits of day surgery depend on how many patients accept same day discharge. This study aims to investigate what proportion of adults undergoing tonsillectomy would accept same day discharge and reasons for refusal. Fifty consecutive adults undergoing in-patient tonsillectomy who satisfied criteria for day surgery were prospectively studied. All patients had the same day case; anaesthetic, tonsillectomy technique, analgesia and antiemetic. Eight hours after surgery patients were given discharge information and asked whether they would accept discharge. Those patients who refused discharge were asked to specify why. Additional morphine requirements were noted. Fifty-two percent of patients would accept same day discharge. Reasons for refusal were; pain 46%, nausea 33%, dizziness 13% and pain and nausea 8%. Those refusing discharge were three times more likely to have received additional morphine. These results compare unfavourably with oversees studies and this may be due to sampling bias. Further studies are required.

Outpatient tonsillectomy and adenoidectomy clinical pathways: an evaluative study

PURPOSE

The purpose of this study is to examine two different dimensions of an outpatient pediatric tonsillectomy and adenoidectomy (T&A) clinical pathway at a tertiary care children's hospital. First, the analysis investigates whether the T&A clinical pathway effectively aids in the decision to discharge a pediatric patient as a day surgery (DS) (less than 12 hours) rather than as an outpatient observation surgery (OPO) (12 to 23 hours). Second, the pathway's impact on quality and financial outcomes is explored.

PATIENTS AND METHODS

Forty prepathway pediatric T&A patients were randomly selected and matched to 40 pathway pediatric T&A patients by age, gender, medical history, and surgeon to form a retrospective cohort. Using chi-square and analysis of variance, the two groups were compared by type of discharge (DS or OPO), length of stay, readmission rates, and costs.

RESULTS

The results show that patients on a pathway were more likely to be discharged as a DS. The shift toward DS discharges effected significant reduction in average length of stay and overall direct costs. Furthermore, there was no difference in readmission rates.

CONCLUSION

These results indicate that the development and implementation of a pathway is an effective method in reducing length of stay and overall direct costs while maintaining quality outcomes.
