RESUMEN
BACKGROUND: It is well known that it is more reliable to investigate the effects of several covariates simultaneously rather than one at time. Similarly, it is more informative to model responses simultaneously, as more often than not, the multiple responses from the same subject are correlated. This is particularly true in the analysis of Mozambique survey data from 2009 and 2018. METHOD: A multiple response predictive model for testing positive for HIV and having sufficient HIV knowledge is modeled to 2009 and 2018 survey data with the use of Bayes estimates. These data are obtained through a hierarchical data structure. The model allows one to address the change in the response to HIV, as it relates to morbidity and to HIV knowledge in Mozambique in the fight against the disease in the last decade. RESULTS: A more affluent resident is more likely to test positive, more likely to be more knowledgeable about the disease. Whereas, individuals practicing the Islam faith are less likely to test positive but also less likely to be knowledgeable about the disease. Education, while still a factor, has declined in its impact on testing positive for HIV or being knowledgeable about HIV. Females are more likely to test positive but more likely to be knowledgeable about the disease than men. The rate of impact of affluence on knowledge has increased in the past decade. Marital status (cohabitating or married) showed no impact on the knowledge of the disease. Age had no impact on knowledge suggesting that the message is getting to resident. CONCLUSIONS: A joint Bayes modeling of correlated binary (testing positive and knowledge about the disease) responses, while accounting for the hierarchy of the data collection, presents an opportunity to extract the extra variation before allocating the variation on the responses as the due of the covariates. The fight against HIV in Mozambique seems to be succeeding. Some knowledge is common among all ages, and Islam religion has a positive effect. While education still shows an influence on the binary responses, it has declined over the last decade.

BACKGROUND: Although the relationship between residential food environments and health outcomes have been extensively studied, the relationship between body mass index (BMI) and multiple food environments have not been fully explored. We examined the relationship between characteristics of three distinct food environments and BMI among elementary school employees in the metropolitan area of New Orleans, LA. We assessed the food environments around the residential and worksite neighborhoods and the commuting corridors. RESEARCH METHODOLOGY/PRINCIPAL FINDINGS: This study combined data from three different sources: individual and worksite data (ACTION), food retailer database (Dunn and Bradstreet), and the U.S. Census TIGER/Line Files. Spatial and hierarchical analyses were performed to explore the impact of predictors at the individual and environmental levels on BMI. When the three food environments were combined, the number of supermarkets and the number of grocery stores at residential food environment had a significant association with BMI (ß = 0.56 and ß = 0.24, p < 0.01), whereas the number of full-service restaurants showed an inverse relationship with BMI (ß = -0.15, p < 0.001). For the commute corridor food environment, it was found that each additional fast-food restaurant in a vicinity of one kilometer traveled contributed to a higher BMI (ß = 0.80, p <0.05), while adjusting for other factors. No statistical associations were found between BMI and worksite food environment. CONCLUSIONS: The current study was the first to examine the relationship between BMI and food environments around residential neighborhoods, work neighborhoods, and the commuting corridor. Significant results were found between BMI and the availability of food stores around residential neighborhoods and the commuting corridor, adjusted for individual-level factors. This study expands the analysis beyond residential neighborhoods, illustrating the importance of multiple environmental factors in relation to BMI.

BACKGROUND: It is unclear whether incidence of detected skin cancer in patients evaluated by store-and-forward teledermatology (SAF) vs. face-to-face consultation (F2F) significantly differs, and whether such differences are because of variations in patient demographics, diagnostic accuracy, or both. METHODS: This retrospective cohort study compares patient skin cancer risk profile, pre-post biopsy diagnostic accuracy, and detection rates of any skin cancer, melanoma, and keratinocytic carcinoma between all SAF teledermatology patients and a subset of randomly selected F2F consultations at VA-Boston Healthcare System in 2014. RESULTS: Patients in the teledermatology (n = 434) and F2F visit cohorts (n = 587) had similar baseline demographics except a higher proportion of F2F patients had prior history of skin cancer, 22% (131/587) vs. 10% (45/434), P < 0.001, and received biopsies, 27.2% (160/587) vs. 11.5% (50/434), P < 0.001. When adjusted for age, immunosuppression, and personal and family history of skin cancer, there were no significant differences between the two cohorts in detection rates for any skin cancer (9.5% vs. 5.8%, P = 0.3), melanoma (0.6% vs. 0%, P = N/A), or keratinocytic carcinoma (8.5% vs. 5.5%, P = 0.7). The two cohorts also had similar pre-post biopsy perfect diagnostic concordance, time from initial consult request to biopsy (45.5 d vs. 47.3 d, P = 0.8), and time from biopsy to definitive treatment (67.5 d vs. 65.4 d, P = 0.8). CONCLUSION: F2F patients were more likely to have prior history of skin cancer and receive biopsies. When adjusted for presence of skin cancer risk factors, incidence of detected melanoma, keratinocytic carcinoma, and any skin cancer was similar between SAF teledermatology and F2F patients.

The direct and indirect costs of dermatology clinic visits are infrequently quantified. Indirect costs, such as the time spent traveling to and from appointments and the value of lost earnings from time away from work, are substantial costs that often are not included in economic analyses but may pose barriers to receiving care. Due to the national shortage of dermatologists, patients may have to wait longer for appointments or travel further to see dermatologists outside of their local community, resulting in high time and travel costs for patients. Patients' lost time and earnings comprise the opportunity cost of obtaining care. A monetary value for this opportunity cost can be calculated by multiplying a patient's hourly wage by the number of hours that the patient dedicated to attending the dermatology appointment. Using a single institution survey, this study quantified the direct and indirect patient costs, including opportunity costs and time burden, associated with dermatology clinic visits to better appreciate the impact of these factors on health care access and dermatologic provider preference.

The objective of this study was to prospectively evaluate the use of point shear wave elastography for the assessment of liver fibrosis and to determine the usefulness and optimal location for obtaining elastography measurements in native and transplanted livers. Point shear wave elastography measurements were obtained from 100 consecutive patients presenting for percutaneous liver biopsy. Measurements were acquired within both the superior right hepatic lobe (segments VII/VIII) via an intercostal approach and the inferior right hepatic lobe (segments V/VI) via a subcostal approach. Analysis of variance was used to assess statistical differences between the degree of fibrosis on percutaneous liver biopsy and elastography measurements. No statistical difference was present when comparing elastography measurements in patients with hepatic steatosis compared with patients without steatosis (P = 0.2759). There was no difference in the accuracy of elastography measurements in native livers versus transplanted livers (P = 0.221). Point shear wave elastography can accurately differentiate between patients with no-to-mild hepatic fibrosis (F0-F1) and moderate-to-severe hepatic fibrosis (≥F2) with sensitivity of 72% and specificity of 69%. Point shear wave elastography can be used as a noninvasive method to assess fibrosis in patients with native or transplanted livers. In addition, measurements can be combined or taken separately from either the superior or inferior right hepatic lobe. The presence of hepatic steatosis does not affect the accuracy of point shear wave elastography. However, shear wave elastography values in patients with body mass index greater than 40 should be interpreted with caution.

OBJECTIVES: Marshall et al (AJR Am J Roentgenol 2012; 199:997-1002) initially demonstrated that the hepatorenal index is an effective and noninvasive tool to screen patients for hepatic steatosis. The aim of this study was to determine whether the hepatorenal index can be accurately calculated directly from a picture archiving and communication system (PACS) quickly and efficiently without the need for the multiple steps and specialized software used to calculate hepatorenal index in the study by Marshall et al. METHODS: We evaluated 99 of the 101 patients included in the study by Marshall et al: patients being followed by hepatologists with plans for liver biopsy. The hepatorenal index was calculated by using Digital Imaging and Communications in Medicine (DICOM) images from a PACS and a markup region-of-interest tool. We compared this value to the value that Marshall et al derived by using specialized software and to standard histologic estimates. We created similar subgroups: patients with steatosis based on histologically estimated intracellular fat exceeding 5% and patients without steatosis. RESULTS: The mean hepatorenal index ± SD for those with steatosis according to histologic findings was 1.87 ± 0.6, and for those without, it was 1.14 ± 0.2. A hepatorenal index of 1.34 or higher had 92% sensitivity for identifying fat exceeding 5%, 85% specificity, a 94% negative predictive value, and a 79% positive predictive value. Substantial agreement was found between the hepatorenal index calculated from DICOM images and macrovesicular fat categorized at the cut point of 1.34 or higher (κ = 0.76; 95% confidence interval, 0.62-0.88; P < .001). CONCLUSIONS: The hepatorenal index can be quickly and accurately calculated from DICOM images directly on a PACS without supplementary software.

BACKGROUND: Diabetic patients should receive self-management education to improve self-care and quality of life but are frequently unable to attend such programs because of the time commitment. We instituted an intensive 2-hour Diabetes Boot Camp to provide this education in a condensed time frame. The objective was to determine the long-term effect of the boot camp on mean hemoglobin A1c (HgA1c) levels in patients with diabetes compared to diabetic patients receiving the standard of care. METHODS: The Diabetes Boot Camp population was defined as all diabetic patients referred to the boot camp from the 10 highest utilizing physicians between August 2009 and August 2010. A control population was randomly selected from these same physicians' diabetic patients during the same period. Baseline and postintervention HgA1c measurements on the same patients in both groups were extracted from the electronic medical record. Subpopulations studied included those with HgA1c ≥9% and <9% at baseline. To evaluate long-term effects, we compared HgA1c levels 3 years later (between July 1, 2012 and December 31, 2012) for all groups. RESULTS: Using comparison-over-time analysis, the overall boot camp group (n=69) showed a mean decrease in HgA1c from 8.57% (SD ± 2.32%) to 7.76% (SD ± 1.85%) vs an increase from 7.92% (SD ± 1.58%) to 8.22% (SD ± 1.82%) in the control group (n=107, P<0.001). Mean length of follow-up was 3.2 (SD ± 0.54) years. CONCLUSION: An intensive 2-hour multidisciplinary diabetes clinic was associated with significant long-term improvements in glycemic control in diabetic participants of the clinic.
RESUMEN
BACKGROUND: Nephrocalcinosis, characterized by intratubular and/or parenchymal deposition of calcium phosphate and calcium oxalate crystals, is frequently seen in renal allograft biopsies; however, the clinical consequence of this histologic finding remains unknown. Kidney transplant recipients with good allograft function usually demonstrate improvement in biochemical parameters; however, persistent hyperparathyroidism remains prevalent in this population of patients. We identified renal allografts with nephrocalcinosis and evaluated the effects on renal allograft function and survival. METHODS: We conducted a single-center, retrospective review of kidney allograft biopsies performed at our center from December 1, 2006 to November 30, 2012. Biopsies with nephrocalcinosis as the primary diagnosis were included in the final analysis. Biochemical parameters at the time of biopsy included serum creatinine, phosphate, calcium, intact parathyroid hormone (iPTH), 25-hydroxy vitamin D, and albumin. Serum creatinine was measured at 1, 3, 6, and 12 months after nephrocalcinosis was diagnosed. The use of calcimimetics, vitamin D analogs, active vitamin D, and bisphosphonates was also reviewed. RESULTS: We identified 12 patients with nephrocalcinosis as the primary diagnosis on renal biopsy. The average age of these patients was 52.2 ± 11.9 years, and the average time since transplantation was 2.3 ± 2.7 years. The baseline serum creatinine was 1.37 ± 0.4 mg/dL before the onset of acute kidney injury (AKI). Mean iPTH and 25-hydroxy vitamin D at the time of AKI were 495.66 ± 358.9 pg/mL and 19.9 ± 13.3 ng/mL, respectively. Renal function deteriorated in all patients, and mean serum creatinine at 12-month follow up was 2.37 ± 1.3 mg/dL (P=0.028). One patient progressed to end-stage renal disease at the end of the study period. CONCLUSION: The histologic finding of nephrocalcinosis is associated with poor renal allograft function. Metabolic abnormalities including hyperparathyroidism persist in renal allograft recipients despite normal allograft function and may be associated with the development of nephrocalcinosis in renal transplant recipients.
RESUMEN
BACKGROUND: Pharmacy refill adherence assesses the medication-filling behaviors, whereas self-report adherence assesses the medication-taking behaviors. We contrasted the association of pharmacy refill and self-reported antihypertensive medication adherence with blood pressure (BP) control and cardiovascular disease (CVD) incidence. METHODS AND RESULTS: Adults (nâ=â2075) from the prospective Cohort Study of Medication Adherence among Older Adults recruited between August 2006 and September 2007 were included. Antihypertensive medication adherence was determined using a pharmacy refill measure, medication possession ratio (MPR; low, medium, and high MPR: <0.5, 0.5 to <0.8, and ≥0.8, respectively) and a self-reported measure, eight-item Morisky Medication Adherence Scale (MMAS-8; low, medium, and high MMAS-8: <6, 6 to <8, and 8, respectively). Incident CVD events (stroke, myocardial infarction, congestive heart failure, or CVD death) through February 2011 were identified and adjudicated. The prevalence of low, medium, and high adherence was 4.5, 23.7, and 71.8% for MPR and 14.0, 34.3, and 51.8% for MMAS-8, respectively. During a median of 3.8 years' follow-up, 240 (11.5%) people had a CVD event. Low MPR and low MMAS-8 were associated with uncontrolled BP at baseline and during follow up. After multivariable adjustment and compared to those with high MPR, the hazard ratios for CVD associated with medium and low MPR were 1.17 [95% confidence interval (CI) 0.87-1.56)] and 1.87 (95% CI: 1.06-3.30), respectively. Compared to those with high MMAS-8, the hazard ratios (95% CI) for MMAS-8 for medium and low MMAS-8 were 1.04 (0.79-1.38) and 0.89 (0.58-1.35), respectively. CONCLUSION: While both adherence measures were associated with BP control, pharmacy refill but not self-report antihypertensive medication adherence was associated with incident CVD. The differences in these associations may be because of the distinctions in what each adherence measure assesses.

BACKGROUND: Cognitive behavioral therapy (CBT) has proven useful in treating fibromyalgia, depression, and anxiety. Computerized delivery of CBT allows increased access to such therapy. This study assessed the effect of internet-based CBT on Fibromyalgia Impact Questionnaire (FIQ) composite scores and tender point assessments. METHODS: This 12-week randomized controlled trial included patients ≥18 years of age with 1990 American College of Rheumatology criteria for fibromyalgia and mild to moderate depression and anxiety. A total of 56 subjects were randomized into either a 6-week internet-based CBT group (MoodGYM) or a control group (standard care). We evaluated patients in both groups at 1-, 6-, and 12-week follow-up. The primary outcome measure was change in FIQ composite score. A secondary outcome measure was change in tender point assessment. RESULTS: The mean age of study participants was 55 years, and 88% were female. Mean FIQ scores were significantly lower in the MoodGYM group compared to the control group (P<0.05 for group differences at 6 and 12 weeks). Mean tender point scores were also significantly lower in the MoodGYM group (P<0.001 at 6 and 12 weeks). We found no significant difference in the FIQ scores across the 3 timepoints in the MoodGYM group, but tender points showed a significant negative trend from baseline to 12-week follow-up. CONCLUSION: Patients in the internet-based MoodGYM CBT program had lower FIQ and tender point scores at 6- and 12-week follow-up. Internet-based CBT could be beneficial in the treatment of mild to moderate depression and anxiety in patients with fibromyalgia by allowing increased access to CBT.
RESUMEN
OBJECTIVE: Some of the deleterious effects of hypoglycemia in hospitalized patients include increased rates of mortality and longer length of stay. Our primary objective was to identify the risk factors associated with severe hypoglycemia to identify those patients at highest risk. METHODS: The medical records of 5,026 patients with diabetes mellitus (DM) admitted in 2010 were reviewed to identify those patients that developed severe hypoglycemia (blood glucose [BG] <40 mg/dL). We performed χ2 tests to assess statistical significance. Adjusted logical regression was used to determine the risk factors for hypoglycemia in the hospital. RESULTS: Out of 5,026 DM patients included in our review, 81 experienced severe hypoglycemia (1.6%). Statistically higher proportions of chronic kidney disease (CKD; 69.1% vs. 46.9%, P<.001), congestive heart failure (CHF; 48.1% vs. 28.5%, P<.001), sepsis (49.4% vs. 12.5%, P<.001), insulin use (45.7% vs. 26.04%, P = .000), type 1 DM (21% vs. 5.1%, P = .000), and cirrhosis (14.8% vs. 7.2%, P = .009) were seen in the severe hypoglycemic group compared to the nonsevere hypoglycemic group. Overall, 84% of patients who experienced an episode of severe hypoglycemia in the hospital (BG <40 mg/dL) had a previous episode of hypoglycemia (BG <70 mg/dL). The odds ratios (ORs) for type 1 DM, sepsis, previous hypoglycemia, and insulin use were 3.43 (95% confidence interval [CI] 1.81, 6.49), 2.64 (95% CI 1.6, 4.35), 46.1 (95% CI 24.76, 85.74), and 1.66 (95% CI 1.02, 2.69), respectively. CONCLUSION: Prior episodes of hypoglycemia in the hospital, the presence of type 1 DM, insulin use, and sepsis were identified as independent risk factors for the development of severe hypoglycemia in the hospital.

BACKGROUND: The white coat's place in the medical profession is a heavily debated topic. Five years after the bare-below-the-elbow policy took effect in England, we reexamined the evidence about coats' potential to transmit infection, reviewed previous studies, and explored our patients' opinions on doctor attire. METHODS: We administered a survey at 3 locations in the Ochsner Health System (hospital clinic, satellite clinic, and inpatient ward) in 2013. The survey assessed patient preference for doctors to wear white coats and included 4 images of the same doctor in different attire: traditional white coat, bare-below-the-elbow attire, a white coat with scrubs, and scrubs alone. Respondents rated images head-to-head for their preferences and individually for their confidence in the physician's skills and for their comfort level with the physician based upon the displayed attire. Participants' attitudes were then reassessed after they were given information about potential disease transmission. RESULTS: Overall, 69.9% of the 153 patients surveyed preferred doctors to wear white coats. When locations were compared, a statistically higher proportion of outpatients preferred coats (P=0.001), a trend most pronounced between hospital clinic (84%) and ward inpatients (51.9%). Patients disliked bare-below-the-elbow attire, scoring it lowest on the comfort and confidence scales (0.05 and 0.09, respectively). Information regarding risks of coat-carried infections did not influence respondents' opinions; 86.9% would still feel comfortable with a doctor who wore one. CONCLUSIONS: These findings suggest patients prefer white coats, and they contribute to greater comfort and confidence in their physicians, despite knowledge of theoretic concerns of disease transmission.
RESUMEN
BACKGROUND: Tobacco use is the world's leading single preventable cause of death. Because children exposed to second- and third-hand smoke are at risk for smoke-related morbidity, pediatricians have an obligation to address tobacco use in their practices. The purpose of this study was to measure physician adherence to the American Academy of Pediatrics' guidelines on tobacco prevention, control, and treatment before and after the implementation of an educational outreach program. METHODS: Charts were randomly selected from pediatric clinics before and after the educational outreach. The intervention consisted of a review of the guidelines and available tools physicians could implement into their practices. We measured the rates of adherence to the guidelines before and after the educational outreach. RESULTS: We analyzed 213 charts (116 pre- and 97 posteducation). The proportion of families screened for tobacco smoke exposure was comparable between the pre- and postintervention groups (67.2% vs 59.8%, P=0.317). The postintervention group had a higher proportion of counseling compared to the preintervention group (51.5% vs 31.9%, P<0.05). We found no statistically significant change in the rate of screening or referral to smoking cessation services. CONCLUSION: Current guidelines to reduce tobacco use are underutilized. Educational outreach may increase the rate of counseling. Physician acceptance of guidelines is urgently needed to affect the tobacco epidemic.
RESUMEN
Increasing global antibiotic resistance has resulted in more use of antibiotic combinations. There is a lack of a gold standard for in vitro testing of these combinations for synergy or antagonism. Time-kill assay (TKA) may be used but is labor intensive and not practical for clinical use. Etest® synergy methods are more rapid and easier to perform, but there is no agreement regarding which method is best. We tested 31 clinical genetically unique Klebsiella pneumoniae carbapenemase-producing Klebsiella isolates with the combination of meropenem and polymyxin B by TKA and 3 Etest methods, each in triplicate: Method 1, MIC:MIC; Method 2, direct overlay; and Method 3, cross. Overall, testing with Etest synergy methods showed the following agreement with TKA: Method 1: 25/31 (80.6%), Method 2: 7/31 (22.6%), and Method 3: 8/31 (25.8%). The MIC:MIC method had the highest agreement (80.6%, κ = 0.59, P < 0.001) and should be evaluated more extensively.

OBJECTIVE: To develop and evaluate a short self-report tool to predict low pharmacy refill adherence in older patients with uncontrolled hypertension. DESIGN: Cross-sectional analysis of survey and administrative data from the Cohort Study of Medication Adherence Among Older Adults (CoSMO). PARTICIPANTS: A total of 394 adults with uncontrolled blood pressure; mean ± SD age was 76.6 ± 5.6 years, 33.0% were black, 66.0% were women, and 23.4% had a low medication possession ratio (MPR). MEASUREMENTS AND MAIN RESULTS: We considered 164 self-reported candidate items for development of a prediction rule for low (less than 0.8) versus high (0.8 or more) MPR from pharmacy refill data. Risk prediction models were evaluated by using best subsets analyses, and the final model was chosen based on clinical relevance and model parsimony. Bootstrap simulations assessed internal validity. The performance of the final four-item model was compared to the eight-item Morisky Medication Adherence Scale (MMAS-8) and the nine-item Hill-Bone Compliance Scale. The four-item self-report tool for predicting pharmacy refill adherence showed moderate discrimination (C statistic 0.704, 95% confidence interval [CI], 0.683-0.714) and good model fit (Hosmer-Lemeshow χ² = 1.238, p=0.743). Sensitivity and specificity were 67.4% and 67.8%, respectively. The concordance (C) statistics for MMAS-8 and the Hill-Bone Compliance Scale were lower at 0.665 (95% CI 0.632-0.683) and 0.660 (95% CI 0.622-0.674), respectively. CONCLUSION: A four-item self-report tool moderately discriminated low from high pharmacy refill adherers, and its test performance was comparable with existing eight- and nine-item adherence scales. Parsimonious self-report tools predicting low pharmacy refill in patients with uncontrolled blood pressure could facilitate hypertension management in the elderly.

OBJECTIVES: To determine whether sociodemographic, clinical, healthcare system, psychosocial, and behavioral factors are differentially associated with low antihypertensive medication adherence scores in older men and women. DESIGN: Cross-sectional analysis of baseline data. SETTING: Cohort Study of Medication Adherence in Older Adults (N = 2,194). MEASUREMENTS: Low antihypertensive medication adherence was defined as a score less than 6 on the 8-item Morisky Medication Adherence Scale. Information on risk factors for low adherence was collected using telephone surveys and administrative databases. RESULTS: The prevalence of low medication adherence scores did not differ according to sex (women, 15.0%; men 13.1%; P = .21). In sex-specific multivariable models, having problems with medication cost and practicing fewer lifestyle modifications for blood pressure control were associated with low adherence scores in men and women. Factors associated with low adherence scores in men but not women were poor sexual functioning (odds ratio (OR) = 2.03, 95% confidence interval (CI) = 1.31-3.16 for men and OR = 1.28, 95% CI = 0.90-1.82 for women), and body mass index of 25.0 kg/m(2) or more (OR = 3.23, 95% CI = 1.59-6.59 for men; OR = 1.23, 95% CI = 0.82-1.85 for women). Factors associated with low adherence scores in women but not men included dissatisfaction with communication with their healthcare provider (OR = 1.75, 95% CI = 1.16-2.65 for women; OR = 1.16, 95% CI = 0.57-2.34 for men) and depressive symptoms (OR = 2.29, 95% CI = 1.55-3.38 for women; OR = 0.93, 95% CI = 0.48-1.80 for men). CONCLUSION: Factors associated with low antihypertensive medication adherence scores differed according to sex. Interventions designed to improve adherence in older adults should be customized to account for the sex of the target population.

BACKGROUND: Intraoperative nerve monitoring (IONM) has been used in head and neck surgery since the 1970s. Its utilization for monitoring and protecting the recurrent laryngeal nerve, however, is a controversial subject. This paper details the use, value, and cost of this technology within a single institution. METHODS: We conducted a retrospective chart review, analysis of surgery time with and without IONM, analysis of postoperative vocal cord function, and review of the literature. RESULTS: IONM did not reduce the operative time during either thyroid lobectomies or total thyroidectomies in 119 surgeries. Use of IONM increased the cost of each surgery by $387. IONM did not decrease the number of injured nerves (postoperative paresis). CONCLUSIONS: IONM has proven to be highly useful in certain circumstances but has not been definitively proven to protect the nerve any more effectively than the gold standard of nerve visualization. In our study, the use of IONM did not reduce the time of thyroid surgery and did increase the cost. While IONM may, in special clinical circumstances such as revision and malignant thyroid surgery, increase the value of the operation, its use for every thyroid surgery does not appear to be cost effective or valuable to the patient.
