Evaluation of the long-term cost-effectiveness of IDegLira versus liraglutide added to basal insulin for patients with type 2 diabetes failing to achieve glycemic control on basal insulin in the USA.

BACKGROUND AND AIMS: IDegLira, a fixed ratio combination of insulin degludec and glucagon-like peptide-1 receptor agonist liraglutide, utilizes the complementary mechanisms of action of these two agents to improve glycemic control with low risk of hypoglycemia and avoidance of weight gain. The aim of the present analysis was to assess the long-term cost-effectiveness of IDegLira vs liraglutide added to basal insulin, for patients with type 2 diabetes not achieving glycemic control on basal insulin in the US setting. METHODS: Projections of lifetime costs and clinical outcomes were made using the IMS CORE Diabetes Model. Treatment effect data for patients receiving IDegLira and liraglutide added to basal insulin were modeled based on the outcomes of a published indirect comparison, as no head-to-head clinical trial data is currently available. Costs were accounted in 2015 US dollars ($) from a healthcare payer perspective. RESULTS: IDegLira was associated with small improvements in quality-adjusted life expectancy compared with liraglutide added to basal insulin (8.94 vs 8.91 discounted quality-adjusted life years [QALYs]). The key driver of improved clinical outcomes was the greater reduction in glycated hemoglobin associated with IDegLira. IDegLira was associated with mean costs savings of $17,687 over patient lifetimes vs liraglutide added to basal insulin, resulting from lower treatment costs and cost savings as a result of complications avoided. CONCLUSIONS: The present long-term modeling analysis found that IDegLira was dominant vs liraglutide added to basal insulin for patients with type 2 diabetes failing to achieve glycemic control on basal insulin in the US, improving clinical outcomes and reducing direct costs.

Improved real-world glycaemic outcomes with liraglutide versus other incretin-based therapies in type 2 diabetes.

AIM: Liraglutide (LIRA) once-daily has provided greater A1C reductions than either exenatide (EXEN) twice-daily or sitagliptin (SITA) once-daily in head-to-head trials. The objective of this analysis is to compare the real-world clinical effectiveness of these agents in the USA. METHODS: Using the IMS Health (Alexandria, VA, USA) integrated claims database, A1C outcomes in patients aged ≥ 18 years with type 2 diabetes (T2D) who initiated either LIRA, EXEN or SITA (including SITA/metformin) were retrospectively compared. Patients included in the analysis had ≥ 1 prescription for LIRA, EXEN or SITA between January and December 2010 (index period) and persisted with their index treatment regimens for 6 months post-index. Outcomes included changes in A1C from baseline (45 days pre-index through 7 days post-index) to follow-up [6 months post-index (± 45)] and the proportion of patients reaching A1C<7%. Multivariable regression models adjusted for confounding factors (e.g. age, comorbidities, baseline A1C and background antidiabetic therapy). RESULTS: The predicted change in A1C from baseline was greater for LIRA patients compared with both SITA (-1.08 vs. -0.68%; treatment difference 0.40%, p < 0.0001) and EXEN (-1.08 vs. -0.75%; treatment difference 0.32%, p < 0.001). Predicted A1C goal achievement, derived from the multivariate logistic regression model, was higher with LIRA compared with both SITA [64.4% (95% confidence interval, CI: 63.5-65.3) vs. 49.4% (95% CI: 48.5-50.4); p < 0.0001] and EXEN [64.4% (95% CI: 63.5-65.3) vs. 53.6% (95% CI: 52.6-54.6); p < 0.0001]. CONCLUSIONS: In clinical practice, LIRA was associated with significantly greater reductions in A1C and improved glycaemic goal attainment compared with either EXEN or SITA among adult patients with T2D.

Activity-based costing via an information system: an application created for a breast imaging center.

Activity-based costing (ABC) is a process that enables the estimation of the cost of producing a product or service. More accurate than traditional charge-based approaches, it emphasizes analysis of processes, and more specific identification of both direct and indirect costs. This accuracy is essential in today's healthcare environment, in which managed care organizations necessitate responsible and accountable costing. However, to be successfully utilized, it requires time, effort, expertise, and support. Data collection can be tedious and expensive. By integrating ABC with information management (IM) and systems (IS), organizations can take advantage of the process orientation of both, extend and improve ABC, and decrease resource utilization for ABC projects. In our case study, we have examined the process of a multidisciplinary breast center. We have mapped the constituent activities and established cost drivers. This information has been structured and included in our information system database for subsequent analysis.

Effect of pediatric surgical practice on the treatment of children with appendicitis.

OBJECTIVE: Acute appendicitis in children is managed by both general surgeons (GSs) and pediatric surgeons (PSs). Our objective was to investigate the economics of surgical care provided by either GSs or PSs for appendicitis. METHODS: The outcome of children within our state who underwent operative treatment for appendicitis (January 1994 to June 1997) by board-certified GSs were compared with the results of PSs. Data were sorted according to patient age and diagnosis according to the International Classification of Diseases, Ninth Revision. Analysis of variance was performed on continuous data, and chi(2) analysis was performed on nominal data; data are depicted as mean +/- standard error of the mean. RESULTS: GSs (n = 2178) managed older children when compared with PSs (n = 1018; 11.0 +/- 0.1 vs 9.1 +/- 0.1 years) and less frequently treated perforated appendicitis (18.8% vs 31.9%). Independent of diagnosis (simple or perforated appendicitis), younger children (0-4 years, 5-8 years, and 9-12 years) who were treated by PSs had a significantly shorter hospital stay and/or decreased hospital charge when compared with those who were treated by GSs. However, older children (13-15 years) seemed to have comparable outcomes. CONCLUSIONS: Younger children with appendicitis have reduced hospital days and charges when they are treated by PSs.

Ultrasound-guided fine-needle aspiration biopsy of the thyroid: role of on-site assessment and multiple cytologic preparations.

Several studies have shown that ultrasound guidance can serve as a valuable aid in improving the diagnostic yield of fine-needle aspiration (FNA) biopsy of thyroid nodules. In this study, we evaluated the combined impact of ultrasound-guidance, rapid on-site evaluation of FNA specimens, and different cytologic preparations (fresh and alcohol-fixed smears, Millipore filter) and staining methods (Diff-Quik and Papanicolaou stains) on the diagnostic yield of thyroid FNA. Ultrasound-guided FNA was performed on 282 patients (313 cases) between November 1997 and April 1999. The diagnostic categories included: benign (198 cases, 63.2%); indeterminate (42 cases, 13.4%); suspicious for follicular variant of papillary carcinoma (26 cases, 8.3%), malignant (32 cases, 10.1%); and nondiagnostic (15 cases, 5%). The nondiagnostic cases also included 6 cystic lesions without any solid component and 3 thyroid-bed aspirations. After excluding these, the nondiagnostic rate was only 2%. Histological follow-up was available in 77 (77/313) cases. The concordance rate between cytological and histological diagnosis was 100% in malignant, 67% in suspicious, and 56% in indeterminate cases. All cases with histologic follow-up were selected to evaluate the independent diagnostic efficacy of each aforementioned cytologic staining method. A definite diagnosis could be made solely on the basis of air-dried, Diff-Quik-stained preparations in 50 (65%), alcohol-fixed, Papanicolaou stained smears in 68 (88%), and Millipore filter preparations in 70 (91%) cases. We conclude that ultrasound-guided FNA combined with on-site evaluation and different cytologic preparations can significantly improve the diagnostic accuracy of thyroid FNA specimens.

Cost comparison of electrocardiography versus fluoroscopy for central venous line positioning in children.

BACKGROUND: Although most central venous lines in children are positioned using fluoroscopy, electrocardiography (ECG) has been shown to be accurate, and avoids unnecessary radiation exposure. We studied whether ECG may also have cost advantages. STUDY DESIGN: All ports and Hickman/Broviac catheters placed during a 2.5-year period were reviewed. Two surgeons routinely used fluoroscopy, and two used ECG. Costs included surgeon and anesthesia fees, operating room use, and fluoroscopy equipment and personnel. RESULTS: There were 287 cases with sufficient data to be included in the study (167 fluoroscopy and 120 ECG). In the ECG group, 12 (10%) were converted to fluoroscopy because an adequate tracing could not be obtained, but they were kept in the ECG group for data analysis. The groups were similar with regard to age, gender, indication, previous catheters, and intraoperative or postoperative complications. Time for surgical placement of the line was not significantly affected by the positioning technique. Ports placed using ECG were less costly than those placed fluoroscopically ($2,880+/-408 versus $3,595+/-357, p<0.001), and the same was true for tunneled external catheters ($2,249 +/- 435 versus $2,923+/-350, p<0.001). CONCLUSIONS: The ECG technique was less costly than fluoroscopy, despite a 10% conversion rate. At our center, the savings were approximately $700 per procedure. Because operating room time used is similar, the additional cost of fluoroscopy can be attributed to the need for x-ray equipment and personnel.

One-stage Soave pull-through for Hirschsprung's disease: a comparison of the transanal and open approaches.

PURPOSE: The authors reviewed their experience using the transanal Soave technique, to determine (1) if it offers any advantages over the standard open approach and (2) whether routine laparoscopic visualization is necessary. METHODS: The case reports of 37 consecutive children less than 3 years old undergoing Soave pull-through were reviewed. Patients were excluded from analysis if they had total colon disease or had a previous colostomy. The patients were divided into 3 groups: open Soave (OS, n = 13), transanal Soave with routine laparoscopic visualization (LVS, n = 9), and transanal Soave with selective laparoscopy or minilaparotomy (TAS, n = 15). Cost was calculated based on hospital stay, operating room time, and use of laparoscopic equipment. RESULTS: In the TAS group, suspicion of a longer segment led to the selective use of laparoscopy with or without biopsy in 2 children, and the use of a small umbilical incision for mobilization of the splenic flexure in 2. There were no differences among groups with respect to age, weight, gender, transition zone, operating time, blood loss, intraoperative complications, enterocolitis, or stricture or cuff narrowing. Hospital stay was significantly longer in the OS group (median, 7 days; range, 3 to 47) than the LVS (median, 1; range 1 to 6) or TAS (median, 1, range, 1 to 3) groups. Cost (in thousands of dollars) was also higher in the OS group (median, 6.9; range, 3.9-25.7) than the LVS (median, 3.9; range, 3.6 to 6.4) or TAS (median, 3.4; range, 2.2 to 9.4) groups. Repeat surgery was necessary for 4 OS patients: 2 adhesive small bowel obstructions (1 of whom died), 1 twisted pull-through, and 1 recurrent aganglionosis. Three TAS patients required repeat surgery: 1 twisted pull-through, 1 anastomotic leak, and 1 cuff narrowing. CONCLUSIONS: These data suggest that the transanal pull-through is associated with a significantly shorter hospital stay and lower cost than the open approach, without an increased risk of complications. Because there is no intraabdominal dissection, there probably is a lower incidence of adhesive bowel obstruction. Routine laparoscopic visualization or minilaparotomy is not necessary but should be used in children who are at higher risk for long segment disease.

Sensitivity and cost minimization analysis of radiology versus olive palpation for the diagnosis of hypertrophic pyloric stenosis.

BACKGROUND/PURPOSE: Two strategies are commonly used for the initial diagnosis of hypertrophic pyloric stenosis (HPS): (1) physical examination and (2) radiologic evaluation using upper gastrointestinal series (UGI) or sonography. The authors wished to determine the sensitivity and relative cost of each strategy. METHODS: The charts of 234 patients presenting over 3 years with a history suggestive of HPS were reviewed retrospectively. Cost, expressed as mean diagnostic charges (MDC) and mean total charges (MTC), was calculated according to two theoretical models. In model A, all patients first are examined by a surgeon. If an olive is palpable, they proceed to surgery. If not, they are sent to radiology. In model B, all patients have radiologic investigation first, and then surgical evaluation if the study result is positive. RESULTS: Of the 234 patients, 150 had HPS (64%). Olives were appreciated in 111 of these (palpation sensitivity of 74%). There was one false-positive olive (0.7%) and no false-negatives. Sonography and UGI were equally accurate (sensitivity of 100%, 0.5% false-positive). Equations were generated to estimate MDC and MTC for our patient population under each model. In model A, MDC = $507 - ($221 x palpation sensitivity) and MTC = $2,543 ($240 x palpation sensitivity). In model B, MDC = $449 and MTC = $2,454, and costs were independent of ability to feel an olive. When cost was plotted against palpation sensitivity, model A yielded a lower MDC than model B if palpation sensitivity was at least 26%, and a lower MTC if palpation sensitivity was at least 37%. Because our palpation sensitivity was 74%, approximately $100 per patient would be saved by sending all infants suspected of having HPS to a surgeon for examination as an initial step. CONCLUSIONS: Although highly sensitive, imaging is superfluous if an olive is palpable. Children suspected of having HPS should have a surgical consultation before a radiology study as long as the surgeon's palpation sensitivity for an olive is at least 37%. Improved palpation skills will result in maximum financial savings.

Repeat pediatric visits to a general emergency department.

STUDY OBJECTIVE: To determine the rate of repeat visits among children cared for in a general emergency department and associated demographic and clinical variables. METHODS: We carried out a chart review of patients seen in the ED of a general hospital serving both inner-city and suburban populations. Our subjects were all children younger than 18 years seen in the study ED between July 1, 1992, and June 30, 1993 (N = 4,276). RESULTS: We found 291 repeat visits (defined as a subsequent visit within 14 days) n 245 children. Among the 242 repeat visits for related complaints, 200 were unanticipated and most without a clear medical need. Mantel-Haenszel adjusted odds ratios (MHORs) showed a significantly increased risk of repeat visit with public insurance (controlled for age: MHOR, 2.57, and 95% confidence interval [CI], 1.93 to 3.43; controlled for race: MHOR, 2.70, and 95% CI, 1.99 to 3.66) and age younger than 2 years (controlled for insurance MHOR, 1.67, and 95% CI, 1.27 to 2.19; controlled for race: MHOR, 1.89, and 95% CI, 1.47 to 2.47. CONCLUSION: Repeat visits were more likely for respiratory diagnoses and less likely for minor trauma. Both visits and repeat visits were more likely in patients from poorer census tracts than in those from equidistant, more affluent ones.

Intrauterine low density in women over 50. Assessment of significance and recommendations for follow-up.

Patients over 50 years old with intrauterine low density on enhanced computed tomography were analyzed. Uterine volume and volume of intrauterine low density were calculated. Intrauterine low density was expressed as a percent of uterine volume. At 1-year follow-up, 23 (63.9%) had uterine malignancy and 13 (36.2%) had benign findings. All patients whose intrauterine low density exceeded 35% of the total uterine volume had a malignancy (p < 0.001). If intrauterine low density exceeds 35% of uterine volume, evaluation of uterine malignancy should be performed regardless of symptoms.

A prospective evaluation of the Button gastrostomy in children.

The Button gastrostomy has become popular for patients requiring long-term enteral feeding, because it is considered less irritating, more stable and more esthetically acceptable than the traditional tube gastrostomy. By a standardized questionnaire and personal interview, the authors evaluated prospectively the efficacy and complication rate in 19 children who had a Button gastrostomy inserted during a 6-month period. In 15 children the Button replaced a standard tube gastrostomy, and in 4 the Button was inserted surgically initially. Thirteen children had severe neurologic disabilities, and 6 required supplemental enteral feeding as part of the nutritional management of another chronic disease. In all 19 children, the Button was esthetically more acceptable and produced less skin irritation than the standard tube gastrostomy. All but one caregiver thought that the Button gastrostomy was preferable to a tube gastrostomy. This was especially apparent in the six neurologically normal children who were able to be more active and had an improved self-image. Cost analysis showed that, despite the higher initial cost of the Button, elimination of the need for frequent tube changes and hospital visits made it ultimately more cost effective than the standard tube gastrostomy. The authors conclude that the Button gastrostomy is a useful alternative to the standard tube gastrostomy in selected patients. Close long-term follow-up is extremely important to ensure a good result.
