'Thinking that somebody's going to delay [a tonsillectomy] for one to two years is quite horrifying really': a qualitative feasibility study for the NAtional Trial of Tonsillectomy IN Adults (NATTINA Part 2).

OBJECTIVES: Level one evidence on the value of adult tonsillectomy versus non-surgical management remains scarce. Before embarking on a costly national randomised controlled trial, it is essential to establish its feasibility. DESIGN: Feasibility study with in-depth qualitative and cognitive interviews. SETTING: ENT staff and patients were recruited from nine hospital centres across England and Scotland. PARTICIPANTS: Patients who were referred for tonsillectomy (n = 15), a convenience sample of general practitioners (n = 11) and ear, nose and throat staff (n = 22). MAIN OUTCOME MEASURES: To ascertain whether ear, nose and throat staff would be willing to randomise patients to the treatment arms. To assess general practitioners' willingness to refer patients to the NAtional Trial of Tonsillectomy IN Adults (NATTINA) centres. To assess patients' willingness to be randomised and the acceptability of the deferred surgery treatment arm. To ascertain whether the study could progress to the pilot trial stage. RESULTS: Ear, nose and throat staff and general practitioners were willing to randomise patients to the proposed NATTINA. Not all ENT staff were in equipoise concerning the treatment pathways. Patients were reluctant to be randomised into the deferred surgery group if they had already waited a substantial time before being referred. CONCLUSIONS: Findings suggest that the NATTINA may not be feasible. Proposed methods could not be realistically assessed without a pilot trial. Due to the importance of the question, as evidenced by NATTINA clinicians, and strong support from ENT staff, the pilot trial proceeded, with modifications.

Tonsillectomy is not a procedure of limited value - the unseen costs of tonsillitis and quinsy on hospital bed consumption.

OBJECTIVES: To assess the impact of the introduction of the SIGN Clinical guidelines in 1999 and subsequent revision in 2005 on tonsillectomy, hospital admission with tonsillitis and peritonsillar abscess rates in four countries. METHODS: Retrospective analysis using English, Welsh, Australian and New Zealand National healthcare hospital admission databases between 2000 and 2013. Primary outcomes measures included tonsillectomy rates and hospital admission rates for tonsillitis and peritonsillar abscess. Secondary outcome measures included bed-day usage in England and Wales. Linear forecasting was used to identify the potential impact of any trends. RESULTS: Following guideline introduction for tonsillectomy, a significant decline in tonsillectomy rates in England (P < 0.01) and Wales (P < 0.05) was seen. Hospital admissions for acute tonsil infections increased in England (P < 0.01) and Wales (P < 0.01). In Australia and New Zealand, tonsillectomy and admission for tonsillitis rates both increased (P < 0.01). During this time, the increased rate of admission for tonsillitis in England and Wales was significantly greater than Australasia (P < 0.01). CONCLUSIONS: Following the introduction of these Clinical guidelines, there was a decrease in the rate of tonsillectomy in England and Wales and a presumed associated increase in admissions with tonsillitis. This did not occur in Australasia where tonsillectomy rates rose over time. If these trends continue, it is likely that they will have a significant deleterious impact on healthcare spending in the future.

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.

Healthcare costs of acute and chronic tonsillar conditions in the pediatric population in the United States.

OBJECTIVE: To determine the prevalence and healthcare costs associated with the diagnosis and treatment of acute and chronic tonsillar conditions (ACT) in children. DESIGN: Cross-sectional analysis of the 2006, 2008, and 2010 Medical Expenditure Panel Surveys. METHODS: Pediatric patients (age < 18 years) were examined from the above mentioned database. From the linked medical conditions file, cases with a diagnosis of ACT were extracted. Ambulatory visit rates, prescription refills, and ambulatory healthcare costs were then compared between children with and without a diagnosis of ACT and acute versus chronic tonsillitis, with multivariate adjustment for age, sex, ethnicity, region, insurance coverage and comorbid conditions (e.g., asthma and otitis media). RESULTS: A total of 74.3 million children (mean age 8.55 years, 51% male) were sampled (raw N = 28,873). Of these, 804,229 children (1.1 ± 0.1%) were diagnosed with ACT annually (mean age 7.24 years, 49.1% male); 64.6 ± 2.0% had acute tonsillitis diagnoses and 35.4 ± 2.0% suffered from chronic tonsillitis. Children with ACT incurred an additional 2.3 office visits and 2.1 prescription fills (both p < 0.001) annually compared with those without ACT, adjusting for demographic variables and medical comorbidities, but did not have an increase in emergency department visits (p = 0.123). Children with acute tonsillar diagnoses carried total healthcare expenditures of $1303 ± 390 annually versus $2401 ± 618 for those with chronic tonsillitis (p = 0.193). ACT was associated with an incremental increase in total healthcare expense of $1685 per child, annually (p < 0.001). CONCLUSION: The diagnosis of ACT confers a significant incremental healthcare utilization and healthcare cost burden on children, parents and the healthcare system. With its prevalence in the United States, pediatric tonsillitis accounts for approximately $1.355 billion in incremental healthcare expense and is a significant healthcare utilization concern. LEVEL OF EVIDENCE: 2C.

Comparison of outcomes and cost in patients undergoing tonsillectomy with electrocautery and thermal welding.

PURPOSE: To assess the morbidity and efficacy of thermal tissue welder instrument for tonsillectomy and compare it with monopolar electrocautery. MATERIALS AND METHODS: IRB approval was obtained at the Wexner Medical Center at Ohio State University for a prospective, randomized, single-blinded, controlled clinical study of 48 healthy adult volunteers undergoing tonsillectomy for chronic tonsillitis and tonsil hypertrophy. Subjects were randomized to the TW or EC group. Post-operative pain, pain medication use, return to normal oral intake, return to normal activity, and bleeding were measured on the post-operative log. We recorded operative time, operating room time, and blood loss. All procedures were performed by one surgeon to eliminate variations in time and experience. Operative and patient data were analyzed using a Student T-test and evaluated by cost analysis. RESULTS: There was a statically significant increase in operative time with the TW taking an average of 4min longer per procedure, p<0.001. However, when total anesthesia time was compared, this did not translate into a statistically significant increase in total operating room time and therefore did not translate into additional cost. The remaining categories were not significantly different between the two groups. In 3/23 TW cases, suction cautery was required for hemostasis. Two patients had 3 occurrences of secondary bleeding in the electrocautery group and none in the tissue welder group. TW cost increase per case was $167 per instrument but averaged $700 per case. CONCLUSIONS: While the tissue welder remains a viable option for the adult tonsillectomy procedure, it has not demonstrated in our study the necessary parameters intraoperatively, postoperatively, or via cost analysis to become the choice instrument at our institution. We cannot ignore the increase in cost that may be seen for short and routine procedures without an added benefit to the patient in terms of outcome or safety. A larger study is needed to determine if secondary bleeding rates are lower with this instrument.

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.

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.

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.

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.

Health care costs of allergic rhinitis-associated conditions vary with allergy season.

BACKGROUND: Studies have documented how allergic respiratory symptoms vary with allergen levels, but the impact of allergen levels on health care expenditures for allergy-related conditions has never been shown using actual data on outdoor allergen levels. Evidence linking respiratory allergy to comorbid conditions has also been scanty. OBJECTIVE: To investigate the link between respiratory allergy and presumably associated conditions by documenting seasonal patterns in their severity and co-occurrence, and to suggest a plan for future research. METHODS: A retrospective, cross-sectional analysis of medical claims data from 1995 to 1996 were linked to monthly data from federal counting stations on outdoor allergen levels. Participants were employed persons and their dependents, living within 15 miles of an allergen-counting station, continuously enrolled in a health plan for 1995 and 1996, and identified through medical claims data as having asthma, allergic rhinitis (AR), migraines, sinusitis, tonsillitis, otitis media, depression, or anxiety disorder. RESULTS: All conditions studied were more likely to occur during allergy season than during nonallergy season. For persons with health care claims for a condition of interest in both seasons, total health care costs during allergy season were significantly higher than during nonallergy season. Predicted condition-related expenditures were higher in allergy season for every condition even after controlling for the effect of AR. CONCLUSION: Allergy effects appear to extend beyond AR symptoms. Other conditions may be affected by outdoor allergen levels even in the absence of AR symptoms, implying that these conditions may be etiologically related to allergy, irrespective of their co-existence with allergic rhinitis, further implying that allergic sensitization can independently affect different parts of the respiratory tract as well as the brain.

The use of multilevel analysis in health economics: an application to examining the effect of competition on general practitioners' behaviour.

Multilevel modelling is a relatively new technique developed in the area of educational research. To illustrate the use of this technique in health economics, this paper estimates a multilevel logit model to examine the effect of competition on the behaviour of Australian general practitioners. The main hypothesis tested is that GPs in areas of high competition are more likely to recommend a follow up consultation compared to GPs in areas of low competition. The results suggest that competition influences the decision to recommend a follow up visit for one out of the five medical conditions analysed. The use of multilevel analysis represents a methodological improvement on previous models of GP behaviour. However, before multilevel analysis is more widely adopted it is argued that it should be more formally assessed against more standard and equivalent methods already used by economists, such as random effects panel data models.

Cost saving of 5-day therapy with cefpodoxime proxetil versus standard 10-day beta-lactam therapy for recurrent pharyngotonsillitis in adults. A prospective general practice study.

A prospective economic evaluation was undertaken as part of a randomised clinical trial conducted in French general practice. Its aim was to compare the costs and therapeutic outcomes of a 5-day course of cefpodoxime proxetil 100 mg twice daily with 10-day courses of phenoxymethylpenicillin (penicillin V) 1 MIU 3 times daily and amoxicillin-clavulanic acid 500/125 mg 3 times daily for the treatment of recurrent pharyngotonsillitis in 575 adults. Over the 6-month study period, the total cost to society per patient treated with cefpodoxime proxetil was 123 French francs (FF; 1993 values) lower than that for patients treated with phenoxymethylpenicillin and FF227 lower than that for patients treated with amoxicillin-clavulanic acid. This cost saving was primarily attributable to a lower initial drug acquisition cost, and a reduction in the cost associated with lost productivity and general practitioner consultations. Furthermore, as a consequence of a lower relapse rate, the cost-saving ratio for cefpodoxime proxetil, expressed as FF per month free of recurrence, was FF50 less than for phenoxymethylpenicillin and FF60 less than for amoxicillin-clavulanic acid. Thus, a 5-day course of cefpodoxime proxetil is likely to be less costly for treatment of pharyngotonsillitis in the general practice setting than standard 10-day courses of phenoxymethylpenicillin and amoxicillin-clavulanic acid.

The economic cost of a streptococcal tonsillitis episode.

OBJECTIVE: To estimate the cost of a streptococcal tonsillitis episode from the data of a questionnaire. SETTING: Five primary health centres in the west of Sweden. PARTICIPANTS: 101 consecutive patients treated for streptococcal tonsillitis. MAIN OUTCOME MEASURE: The cost estimation included costs for physician visit and drug, travel costs to and from the primary health centre, cost of lost production resulting from the patient's or the guardian's absence from work for physician visit or sick-leave, and cost of telephone consultation with a physician or nurse. RESULTS: The period of illness was on average seven days, time to recovery after treatment five days, and the mean period of sick-leave 2.5 days. The total cost of a tonsillitis episode was about SEK 3,300 (385 USD). Of this sum, the cost for the antibiotic accounted for only 3% and loss of production for 75%. CONCLUSION: Differences in the cost of drugs only have a minor influence on the total cost, while factors causing loss of production, such as efficacy and side effects of the drug, have a greater influence. Economic evaluation of pharmaceuticals will be more relevant in the future, and in the search for the most effective treatment, cost effective studies will be integrated with clinical trials.

A double-blind randomized trial comparing the efficacy and safety of a 5-day course of cefotiam hexetil with that of a 10-day course of penicillin V in adult patients with pharyngitis caused by group A beta-haemolytic streptococci.

A 10-day course of penicillin is the antibiotic regimen currently recommended by the American Heart Association (AHA) as treatment for patients with tonsillitis caused by group A beta-haemolytic streptococci (GABHS), with the aim of preventing both the suppurative and non-suppurative complications of this infection. This prospective, multicentre, randomized, double-blind, double-dummy clinical trial was undertaken in order to compare the efficacy of, tolerability of and compliance with a 5-day course of cefotiam hexetil (CTM) 200 mg bd with that of a 10-day course of penicillin V (PEV) 1 megaunit (600 mg) tds, to investigate the significance of recovering GABHS during or after treatment and to evaluate the potential economic advantages of short-term regimens. Two hundred and fifty ambulatory adult patients with a presumptive diagnosis (based on a positive rapid antigen detection test) of GABHS tonsillitis were recruited in 60 centres; the diagnosis was subsequently confirmed by a positive culture of a throat swab. At the time of entry into the trial there was no statistically significant difference between the groups in terms of clinical symptoms. In an intention-to-treat analysis, both the clinical and bacteriological response rates at days 10 and 30 were comparable for each group i.e. 106 of 119 (89.1%) patients and 90 of 109 (82.6%) patients respectively in the CTM group and 103 of 117 (88.0%) patients and 92 of 107 (86.0%) patients respectively in the PEV group. The times until defervescence and resolution of symptoms were also similar. Of the 115 patients in each group who were assessed at day 90, there were three clinical relapses in the CTM group and seven in the PEV group. No non-suppurative complications of GABHS infection were detected. Tolerance was significantly better in the CTM group than in the PEV group, 14 of 119 (11.8%) patients and 26 of 117 (22.2%) patients in the former and latter groups respectively reporting adverse events. In three cases in each group treatment was discontinued prematurely because of adverse events; none of these in the CTM group was serious but one patient in the PEV group experienced a severe allergic reaction. Compliance in both groups was good during the first 5 days of therapy but, by the end of each course, 93.6% of patients in the CTM group had completed treatment, compared with 73.0% in the PEV group.(ABSTRACT TRUNCATED AT 400 WORDS)

Physician response to the United Mine Workers' cost-sharing program: the other side of the coin.

The effect of cost sharing on health services utilization is analyzed from a new perspective, that is, its effects on physician response to cost sharing. A primary data set was constructed using medical records and billing files from a large multispecialty group practice during the three-year period surrounding the introduction of cost sharing to the United Mine Workers Health and Retirement Fund. This same group practice also served an equally large number of patients covered by United Steelworkers' health benefit plans, for which similar utilization data were available. The questions addressed in this interinsurer study are: (1) to what extent does a physician's treatment of medically similar cases vary, following a drop in patient visits as a result of cost sharing? and (2) what is the impact, if any, on costs of care for other patients in the practice (e.g., "spillover effects" such as cost shifting)? Answers to these kinds of questions are necessary to predict the effects of cost sharing on overall health care costs. A fixed-effects model of physician service use was applied to data on episodes of treatment for all patients in a private group practice. This shows that the introduction of cost sharing to some patients in a practice does, in fact, increase the treatment costs to other patients in the same practice who remain under stable insurance plans. The analysis demonstrates that when the economic effects of cost sharing on physician service use are analyzed for all patients within a physician practice, the findings are remarkably different from those of an analysis limited to those patients directly affected by cost sharing.
