Improving the adoption of thyroid cancer clinical practice guidelines.

OBJECTIVES/HYPOTHESIS: To present an overview of the barriers to the implementation of clinical practice guidelines (CPGs) in thyroid cancer management and to introduce a computer-based clinical support system. DATA SOURCES: PubMed. REVIEW METHODS: A review of studies on adherence to CPGs was conducted. RESULTS: Awareness and adoption of CPGs is low in thyroid cancer management. Barriers to implementation include unfamiliarity with the CPGs and financial concerns. Effective interventions to improve adherence are possible, especially when they are readily accessible at the point of care delivery. Computerized clinical support systems show particular promise. The authors introduce the clinical decision making modules (CDMMs) of the Thyroid Cancer Care Collaborative, a thyroid cancer-specific electronic health record. These computer-based modules can assist clinicians with implementation of these recommendations in clinical practice. CONCLUSION: Computer-based support systems can help clinicians understand and adopt the thyroid cancer CPGs. By integrating patient characteristics and guidelines at the point of care delivery, the CDMMs can improve adherence to the guidelines and help clinicians provide high-quality, evidence-based, and individualized patient care in the management of differentiated thyroid cancer.

ACTIVE SURVEILLANCE FOR PAPILLARY THYROID MICROCARCINOMA: NEW CHALLENGES AND OPPORTUNITIES FOR THE HEALTH CARE SYSTEM.

OBJECTIVE: The dramatic increase in papillary thyroid carcinoma (PTC) is primarily a result of early diagnosis of small cancers. Active surveillance is a promising management strategy for papillary thyroid microcarcinomas (PTMCs). However, as this management strategy gains traction in the U.S., it is imperative that patients and clinicians be properly educated, patients be followed for life, and appropriate tools be identified to implement the strategy. METHODS: We review previous active surveillance studies and the parameters used to identify patients who are good candidates for active surveillance. We also review some of the challenges to implementing active surveillance protocols in the U.S. and discuss how these might be addressed. RESULTS: Trials of active surveillance support nonsurgical management as a viable and safe management strategy. However, numerous challenges exist, including the need for adherence to protocols, education of patients and physicians, and awareness of the impact of this strategy on patient psychology and quality of life. The Thyroid Cancer Care Collaborative (TCCC) is a portable record keeping system that can manage a mobile patient population undergoing active surveillance. CONCLUSION: With proper patient selection, organization, and patient support, active surveillance has the potential to be a long-term management strategy for select patients with PTMC. In order to address the challenges and opportunities for this approach to be successfully implemented in the U.S., it will be necessary to consider psychological and quality of life, cultural differences, and the patient's clinical status.

Database and registry research in thyroid cancer: striving for a new and improved national thyroid cancer database.

BACKGROUND: Health registries have become extremely powerful tools for cancer research. Unfortunately, certain details and the ability to adapt to new information are necessarily limited in current registries, and they cannot address many controversial issues in cancer management. This is of particular concern in differentiated thyroid cancer, which is rapidly increasing in incidence and has many unknowns related to optimal treatment and surveillance recommendations. SUMMARY: In this study, we review different types of health registries used in cancer research in the United States, with a focus on their advantages and disadvantages as related to the study of thyroid cancer. This analysis includes population-based cancer registries, health systems-based cancer registries, and patient-based disease registries. It is important that clinicians understand the way data are collected in, as well as the composition of, these different registries in order to more critically interpret the clinical research that is conducted using that data. In an attempt to address shortcoming of current databases for thyroid cancer, we present the potential of an innovative web-based disease management tool for thyroid cancer called the Thyroid Cancer Care Collaborative (TCCC) to become a patient-based registry that can be used to evaluate and improve the quality of care delivered to patients with thyroid cancer as well as to answer questions that we have not been able to address with current databases and registries. CONCLUSION: A cancer registry that follows a specific patient, is integrated into physician workflow, and collects data across different treatment sites and different payers does not exist in the current fragmented system of healthcare in the United States. The TCCC offers physicians who treat thyroid cancer numerous time-saving and quality improvement services, and could significantly improve patient care. With rapid adoption across the nation, the TCCC could become a new paradigm for database research in thyroid cancer to improve our understanding of thyroid cancer management.

Management of recurrent and persistent metastatic lymph nodes in well-differentiated thyroid cancer: a multifactorial decision-making guide for the Thyroid Cancer Care Collaborative.

BACKGROUND: Well-differentiated thyroid cancer (WDTC) recurs in up to 30% of patients. Guidelines from the American Thyroid Association (ATA) and the National Comprehensive Cancer Network (NCCN) provide valuable parameters for the management of recurrent disease, but fail to guide the clinician as to the multitude of factors that should be taken into account. The Thyroid Cancer Care Collaborative (TCCC) is a web-based repository of a patient's clinical information. Ten clinical decision-making modules (CDMMs) process this information and display individualized treatment recommendations. METHODS: We conducted a review of the literature and analysis of the management of patients with recurrent/persistent WDTC. RESULTS: Surgery remains the most common treatment in recurrent/persistent WDTC and can be performed with limited morbidity in experienced hands. However, careful observation may be the recommended course in select patients. Reoperation yields biochemical remission rates between 21% and 66%. There is a reported 1.2% incidence of permanent unexpected nerve paralysis and a 3.5% incidence of permanent hypoparathyroidism. External beam radiotherapy and percutaneous ethanol ablation have been reported as therapeutic alternatives. Radioactive iodine as a primary therapy has been reported previously for metastatic lymph nodes, but is currently advocated by the ATA as an adjuvant to surgery. CONCLUSION: The management of recurrent lymph nodes is a multifactorial decision and is best determined by a multidisciplinary team. The CDMMs allow for easy adoption of contemporary knowledge, making this information accessible to both patient and clinician.

What is the gold standard for comprehensive interinstitutional communication of perioperative information for thyroid cancer patients? A comparison of existing electronic health records with the current American Thyroid Association recommendations.

BACKGROUND: Appropriate management of well-differentiated thyroid cancer requires treating clinicians to have access to critical elements of the patient's presentation, surgical management, postoperative course, and pathologic assessment. Electronic health records (EHRs) provide an effective method for the storage and transmission of patient information, although most commercially available EHRs are not intended to be disease-specific. In addition, there are significant challenges for the sharing of relevant clinical information when providers involved in the care of a patient with thyroid cancer are not connected by a common EHR. In 2012, the American Thyroid Association (ATA) defined the critical elements for optimal interclinician communication in a position paper entitled, "The Essential Elements of Interdisciplinary Communication of Perioperative Information for Patients Undergoing Thyroid Cancer Surgery." SUMMARY: We present a field-by-field comparison of the ATA's essential elements as applied to three contemporary electronic reporting systems: the Thyroid Surgery e-Form from Memorial Sloan-Kettering Cancer Center (MSKCC), the Alberta WebSMR from the University of Calgary, and the Thyroid Cancer Care Collaborative (TCCC). The MSKCC e-form fulfills 21 of 32 intraoperative fields and includes an additional 14 fields not specifically mentioned in the ATA's report. The Alberta WebSMR fulfills 45 of 82 preoperative and intraoperative fields outlined by the ATA and includes 13 additional fields. The TCCC fulfills 117 of 120 fields outlined by the ATA and includes 23 additional fields. CONCLUSIONS: Effective management of thyroid cancer is a highly collaborative, multidisciplinary effort. The patient information that factors into clinical decisions about thyroid cancer is complex. For these reasons, EHRs are particularly favorable for the management of patients with thyroid cancer. The MSKCC Thyroid Surgery e-Form, the Alberta WebSMR, and the TCCC each meet all of the general recommendations for effective reporting of the specific domains that they cover in the management of thyroid cancer, as recommended by the ATA. However, the TCCC format is the most comprehensive. The TCCC is a new Web-based disease-specific database to enhance communication of patient information between clinicians in a Health Insurance Portability and Accountability Act (HIPAA)-compliant manner. We believe the easy-to-use TCCC format will enhance clinician communication while providing portability of thyroid cancer information for patients.

Improving the quality of thyroid cancer care: how does the Thyroid Cancer Care Collaborative cross the Institute of Medicine's Quality Chasm?

BACKGROUND: The current systems of healthcare delivery in the United States suffer from problems that often leave patients with inadequate quality of care. In their report entitled "Crossing the Quality Chasm," the Institute of Medicine (IOM) identified reasons for poor and/or inconsistent quality of healthcare delivery and provided recommendations to improve it. The purpose of this review is to describe features of an innovative web-based program called the Thyroid Cancer Care Collaborative (TCCC) and see how it addresses IOM recommendations to improve the quality of healthcare delivery. SUMMARY: The TCCC addresses the three actionable IOM recommendations directed at healthcare organizations and clinicians to redesign the care process. It does so by exploiting information technology (IT) in ways suggested by the IOM, and it fits within a set of 10 rules provided by the IOM. Some features of the TCCC include: (i) automated disease staging based on three validated scoring systems; (ii) highly illustrated educational videos on all aspects of thyroid cancer care; (iii) personalized clinical decision-making modules for clinicians and physicians; (iv) portability of data to share among treating physicians; (v) virtual tumor boards, "ask the expert," and frequently asked questions modules; (vi) physician workflow integration; and (vii) data for comprehensive analysis to answer difficult questions in thyroid cancer management. CONCLUSION: The TCCC has the potential to improve thyroid cancer care delivery and offers several benefits to patients, clinicians, and researchers. The TCCC is a valuable example of how IOM initiatives can improve the healthcare system.

The endocrinology of exercise.

Some obese individuals do not get cardiovascular disease, diabetes, or certain cancers associated with obesity. These healthy obese individuals exercise regularly and reduce circulating levels of inflammatory mediators which are associated with the complications of obesity. Bloated white adipocytes located in ectopic locations such as the liver, produce these inflammatory mediators. Exercise, by reducing the excess storage of fat in these bloated fat cells, reduces the levels of circulating inflammatory mediators. The processes of gathering and creating new energy-rich substances, storing energy, and consuming energy-rich substances, and the specific contribution of several hormones to this process, are reviewed.

Pathogenic potential of adipose tissue and metabolic consequences of adipocyte hypertrophy and increased visceral adiposity.

When caloric intake exceeds caloric expenditure, the positive caloric balance and storage of energy in adipose tissue often causes adipocyte hypertrophy and visceral adipose tissue accumulation. These pathogenic anatomic abnormalities may incite metabolic and immune responses that promote Type 2 diabetes mellitus, hypertension and dyslipidemia. These are the most common metabolic diseases managed by clinicians and are all major cardiovascular disease risk factors. 'Disease' is traditionally characterized as anatomic and physiologic abnormalities of an organ or organ system that contributes to adverse health consequences. Using this definition, pathogenic adipose tissue is no less a disease than diseases of other body organs. This review describes the consequences of pathogenic fat cell hypertrophy and visceral adiposity, emphasizing the mechanistic contributions of genetic and environmental predispositions, adipogenesis, fat storage, free fatty acid metabolism, adipocyte factors and inflammation. Appreciating the full pathogenic potential of adipose tissue requires an integrated perspective, recognizing the importance of 'cross-talk' and interactions between adipose tissue and other body systems. Thus, the adverse metabolic consequences that accompany fat cell hypertrophy and visceral adiposity are best viewed as a pathologic partnership between the pathogenic potential adipose tissue and the inherited or acquired limitations and/or impairments of other body organs. A better understanding of the physiological and pathological interplay of pathogenic adipose tissue with other organs and organ systems may assist in developing better strategies in treating metabolic disease and reducing cardiovascular disease risk.

The role of intraoperative rapid parathyroid hormone monitoring for predicting thyroidectomy-related hypocalcemia.

OBJECTIVE: To determine if the intraoperative rapid parathyroid hormone (PTH) assay can be used to accurately predict postoperative calcium levels following total or completion thyroidectomy. DESIGN: A prospective study. SETTING: Tertiary care referral center. PATIENTS: One hundred four patients following a total or completion thyroidectomy.Intervention Intraoperative rapid plasma PTH levels were determined for patients undergoing a total or completion thyroidectomy. MAIN OUTCOME MEASURES: Parathyroid hormone levels were recorded after the induction of anesthesia, before excision, and 5, 10, and 20 minutes after thyroidectomy. Postoperative calcium levels were monitored every 6 hours until hospital discharge. Intraoperative PTH levels were correlated with postoperative calcium levels and clinical symptoms of hypocalcemia. RESULTS: Twenty-two patients (21.2%) required short-term postoperative calcium supplementation, and 2 (1.9%) required long-term calcium replacement. There was a statistically significant difference between those patients requiring calcium replacement and those who did not require calcium supplementation, for postoperative total calcium level (7.2 vs 8.1 mg/dL [1.8 vs 2.0 mmol/L]; P<.001) and ionized calcium level (3.76 vs 4.36 mg/dL [0.94 vs 1.09 mmol/L]; P<.001). In addition, the PTH changes from baseline demonstrated statistically significant differences at 5, 10, and 20 minutes after the excision between the 2 groups (P<.005). In those patients requiring calcium supplementation, 14 (64%) of 22 demonstrated a change in PTH level at 20 minutes of greater than 75% from baseline, and in those patients who did not require postoperative calcium supplementation, 61 (74%) of 82 demonstrated a change in PTH level of less than 75% from baseline (P<.005). CONCLUSION: Intraoperative PTH monitoring may be a useful tool in identifying patients who will not require postoperative calcium supplementation following total or completion thyroidectomy.

Parathyroid adenoma autoinfarction: a report of a case.

BACKGROUND: Parathyroid adenoma autoinfarction, although uncommon, is an entity that has been previously reported in the literature; however, the influence of intraoperative parathyroid hormone (PTH) monitoring on therapeutic management has not been reported. METHODS: We present a case of parathyroid autoinfarction that is unique in that it applies a new technology to parathyroid surgery: intraoperative PTH monitoring. RESULTS: Intraoperative PTH monitoring aided in the successful surgical management of this patient. CONCLUSIONS: Intraoperative PTH monitoring can serve as a therapeutic adjunct in the surgical management of parathyroid adenoma autoinfarction.

Preoperative parathyroid localization: correlating false-negative technetium 99m sestamibi scans with parathyroid disease.

OBJECTIVE/HYPOTHESIS: The recent trend toward minimally invasive directed parathyroid surgery has increased the surgeon's reliance on preoperative parathyroid localization. Technetium Tc 99m sestamibi scanning is generally viewed as the gold standard for preoperative localization, with reported sensitivities of 75% to 100% and specificities of 75% to 90%. However, in each reported series there exists a group of patients in whom preoperative localization is either equivocal or negative. STUDY DESIGN: We focused on a subset of patients from our parathyroid database with false-negative sestamibi (MIBI) scans, in an attempt to elucidate features that could affect these studies. We identified 20 patients with negative preoperative scans and confirmed parathyroid disease. We compared them with 22 consecutive patients with positive scans, correlating the following variables: patient age, gender, concomitant thyroid disease (Hashimoto's thyroiditis, papillary thyroid carcinoma, thyroid adenoma), preoperative parathyroid hormone values, location and number of enlarged parathyroid glands, parathyroid weight, and the relative proportion of chief cells, clear cells, oxyphil cells, and adipose tissue. METHODS: Retrospective chart review of clinicopathological and radiological findings. RESULTS: We found that patients with false-negative scans were more likely to have an enlarged parathyroid containing a high proportion of clear cells (P =.01). A trend was seen (P =.1) correlating increased parathyroid fat content and false-negative scans. Conversely, positive preoperative scans were more likely to be associated with a higher percentage of oxyphil cells (P =.02). Univariate analysis for other variables, as well as logistic regression analysis, did not achieve statistical significance. CONCLUSIONS: To date, the present study is the largest clinicopathological review of patients with false-negative sestamibi scans. Technetium Tc 99m uptake correlates with parathyroid oxyphil cell content, and false-negative scans can occur with parathyroid glands containing predominantly clear cells.
