How can information extraction ease formalizing treatment processes in clinical practice guidelines? A method and its evaluation.

Artif Intell Med. 2006 Sep 7;

Authors: Kaiser K, Akkaya C, Miksch S

OBJECTIVE: Formalizing clinical practice guidelines (CPGs) for a subsequent computer-supported processing is a challenging, but burdensome and time-consuming task. Existing methods and tools to support this task demand detailed medical knowledge, knowledge about the formal representations, and a manual modeling. Furthermore, formalized guideline documents mostly fall far short in terms of readability and understandability for the human domain modeler. METHODS AND MATERIAL: We propose a new multi-step approach using information extraction methods to support the human modeler by both automating parts of the modeling process and making the modeling process traceable and comprehensible. This paper addresses the first steps to obtain a representation containing processes which is independent of the final guideline representation language. RESULTS: We have developed and evaluated several heuristics without the need to apply natural language understanding and implemented them in a framework to apply them to several guidelines from the medical subject of otolaryngology. Findings in the evaluation indicate that using semi-automatic, step-wise information extraction methods are a valuable instrument to formalize CPGs. CONCLUSION: Our evaluation shows that a heuristic-based approach can achieve good results, especially for guidelines with a major portion of semi-structured text. It can be applied to guidelines irrespective to the final guideline representation format.

Impact of gestational diabetes mellitus nutrition practice guidelines implemented by registered dietitians on pregnancy outcomes.

J Am Diet Assoc. 2006 Sep;106(9):1426-33

Authors: Reader D, Splett P, Gunderson EP,

Nutrition practice guidelines were developed for gestational diabetes mellitus by registered dietitians from the Diabetes Care and Education and the Women’s Health and Reproductive Nutrition dietetic practice groups. To validate the guidelines, a clinical trial was designed with clinic sites randomly assigned to either nutrition practice guidelines care (12 sites) or usual nutrition care (13 sites), with diabetes, obstetric, and other clinic types represented in both groups. Volunteer dietitians served as study coordinators and recruited women diagnosed with gestational diabetes mellitus. The nutrition practice guidelines define medical nutrition therapy (MNT) for gestational diabetes and emphasize three areas-definition of MNT clinical goals with indexes to modify or advance MNT and criteria to start insulin; use of self-monitoring tools; and provision of three nutrition visits. Usual care sites provided prenatal nutrition care according to usual practice. The effect of nutrition care (sites following the nutrition care guidelines) and type of clinic site on changes in glycated hemoglobin and infant birth weight, adjusted for other covariates, were evaluated using linear regression. Differences in insulin use and other infant outcomes between treatment groups were evaluated using logistic regression. Generalized estimating equations were used to accommodate nonindependence within randomized clusters of patients within clinic sites. Data from 215 women indicated less insulin use at diabetes clinic sites in the nutrition practice guidelines groups and improved glycated hemoglobin control during the treatment period in diabetes clinics compared with obstetric or other clinics. A higher proportion of women in the usual care group had glycated hemoglobin levels that exceeded 6% at follow-up compared with women in the nutrition practice guidelines group (13.6% vs 8.1%), although not statistically significant (P=0.26). A significant clinic type and treatment group effect was found for birth weight. Nutrition practice guidelines for gestational diabetes mellitus reflected nutrition care already being provided by registered dietitians in diabetes clinics prior to this study because outcomes at these clinics were not impacted. Use of the guidelines by dietitians at obstetric and other clinics tended to improve outcomes at these sites.

How does current care practice influence the experience of a new diagnosis of motor neuron disease? A qualitative study of current guidelines-based practice.

Amyotroph Lateral Scler. 2006 Sep;7(3):161-6

Authors: Hugel H, Grundy N, Rigby S, Young CA

Management during the diagnostic phase of MND is considered an important influence on the patient’s further disease course. Guidelines for the management of MND have been developed, but little is known on how recommended practices influence patients’ experience of a new diagnosis of MND. We undertook an interview-based study exploring issues surrounding the diagnosis of MND in a sample of consecutive patients recently diagnosed at a neurosciences centre. Data were analysed with Interpretative Phenomenological Analysis (IPA). Thirteen patients were recruited to the study. The major themes identified in descending order were ‘Family/carers’, ‘Communication of the diagnosis’, ‘Reaction to the diagnosis’, ‘Physical difficulties’, ‘Time before diagnosis’, ‘Information’, ‘Future’, ‘Coping with the diagnosis’ and ‘Formal support’. Communication was perceived satisfactory if handled according to existing guidelines. Physical difficulties impacted considerably on patients’ lives. Delays in the diagnostic process appeared in various interviews. Five patients were avoiding information following the diagnosis. Some patients commented on an increasing number of uncoordinated services becoming involved after their diagnosis. This study supports the current international guidelines for MND care around diagnosis from the patients’ perspective and underlines the importance of a multi-disciplinary, coordinated approach for patients with MND from diagnosis onwards.

Guidelines for chronic obstructive pulmonary disease treatment and issues of implementation.

Proc Am Thorac Soc. 2006 Sep;3(7):641-4

Authors: Rabe KF

Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. Treatment advances over the last decade, although limited, have precipitated the development of clinical practice guidelines, with the aim of improving the quality of care received by patients through fostering evidence-based decision making and accelerating the application of new advances to everyday practice. Of the COPD guidelines that have been developed, those developed through the Global Initiative for Chronic Obstructive Lung Disease (GOLD), initially a joint activity between the U.S. National Heart, Lung, and Blood Institute and the World Health Organization, and the National Institute of Clinical Excellence (NICE) in the United Kingdom have both published their methods for evaluation of evidence. These comprehensive guidelines cover all aspects of the disease, with the aim of providing the basis for local care pathways. The guideline development process includes evaluation of the evidence, development of the guideline, and dissemination of the findings. Efforts to enhance guideline effectiveness have focused on improving the methods and approaches to implementation, which requires an appreciation of the issues that stop translation of guideline definitions of best practice into improved patient care. A variety of questions remain unanswered in the clinical management of COPD, including the definition of outcome measures that move beyond lung function, the potential application of multidimensional grading systems that assess respiratory and systemic expressions of COPD and that could possibly better categorize and predict outcome in these patients, and the impact of new clinical trial findings. Large ongoing outcome studies may also have an effect on defining best practice within future guideline recommendations.

Improved clinical outcomes with utilization of a community-acquired pneumonia guideline.

Chest. 2006 Sep;130(3):794-9

Authors: Dean NC, Bateman KA, Donnelly SM, Silver MP, Snow GL, Hale D

BACKGROUND: We previously reported decreased mortality following implementation of a community-acquired pneumonia guideline derived from specialty society recommendations. However, patients with respiratory failure and sepsis from pneumonia were not included, adjustment for comorbidities was limited, and no guideline compliance data were available. We also questioned whether decreased mortality continued after 1997. METHODS: We utilized Utah data from the Centers for Medicare and Medicaid from 1993 to 2003 to determine if pneumonia guideline implementation was associated with 30-day all-cause mortality, length of hospital stay, and readmission rate. We adjusted outcomes by age, gender, Deyo comorbidity score, prior hospitalizations, and race. Guideline compliance was measured by initial default guideline antibiotic administration. We included patients > or = 66 years old with primary International Classification of Diseases, Ninth Revision, Clinical Modification codes 480.0-483.9, 485.0-486.9, 487.0, 507.0 or 518.81, and 038.x with secondary code pneumonia. We excluded patients with prior hospitalization within 10 days, patients with HIV infection or transplant recipients, and patients not treated by physicians closely affiliated with study hospitals. RESULTS: Mean (+/- SD) age of 17,728 pneumonia patients admitted to the hospital was 72.3 +/- 12.0 years, 55.2% were female, and 96.0% were white. Within Intermountain Healthcare hospitals, a 1-SD increase (10%) in guideline compliance (range, 61 to 100%) was associated with mortality odds ratio (OR) of 0.92 (95% confidence interval[CI], 0.87 to 0.98; p = 0.007). Mortality OR at 16 Intermountain Healthcare hospitals was 0.89 (95% CI, 0.82 to 0.97; p = 0.007) compared with 19 other Utah hospitals. This mortality difference corresponds to approximately 20 lives saved yearly. The readmission rate was also lower. CONCLUSION: Improved clinical outcomes were associated with pneumonia guideline utilization.

Guidelines for the evaluation of intravenous desmopressin and von Willebrand factor/factor VIII concentrate in the treatment and prophylaxis of bleedings in von Willebrand disease types 1, 2, and 3.

Semin Thromb Hemost. 2006 Sep;32(6):636-45

Authors: Michiels JJ, Gadisseur A, van der Planken M, Schroyens W, van de Velden A, Berneman Z

The current standard for the diagnosis and management of patients with congenital von Willebrand disease (vWD) includes bleeding times (BTs), PFA-100 closure time (PFA-CT), factor (F) VIII:coagulant activity (C), vWF:antigen (Ag), vWF:ristocetin cofactor activity (RCo), a sensitive vWF:collagen-binding activity (CB), ristocetin-induced platelet aggregation (RIPA), analysis of vWF multimers in low- and high-resolution agarose gels, and the response to desmopressin. Guidelines and recommendations for prophylaxis and treatment of bleedings in vWD patients with vWF/FVIII concentrates should be derived from analysis of the content of these concentrates and from pharmacokinetic studies in different types of vWD patients with severe type 1, 2, or 3 vWD. The vWF/FVIII concentrates should be characterized by labeling with FVIII:C, vWF:RCo, vWF:CB, and vWF multimeric pattern, which will determine their predicted efficacy and safety in prospective management studies. Because the bleeding tendency is moderate in type 2 and severe in type 3 vWD, and because the FVIII:C levels are subnormal in type 2 and very low in type 3 vWD patients, new guidelines using vWF:RCo unit dosing for the prophylaxis and treatment of bleeding episodes are proposed. Such guidelines should be stratified for the severity of bleeding, the type of surgery (either minor or major), and also for the severity and type of vWD (i.e., either type 2 or 3 vWD).

Fabry disease: guidelines for the evaluation and management of multi-organ system involvement.

Genet Med. 2006 Sep;8(9):539-48

Authors: Eng CM, Germain DP, Banikazemi M, Warnock DG, Wanner C, Hopkin RJ, Bultas J, Lee P, Sims K, Brodie SE, Pastores GM, Strotmann JM, Wilcox WR

Fabry disease is an X-linked metabolic storage disorder due to the deficiency of lysosomal alpha-galactosidase A, and the subsequent accumulation of glycosphingolipids, primarily globotriaosylceramide, throughout the body. Males with classical Fabry disease develop early symptoms including pain and hypohidrosis by the second decade of life reflecting disease progression in the peripheral and autonomic nervous systems. An insidious cascade of disease processes ultimately results in severe renal, cardiac, and central nervous system complications in adulthood. The late complications are the main cause of late morbidity, as well as premature mortality. Disease presentation in female heterozygotes may be as severe as in males although women may also remain asymptomatic. The recent introduction of enzyme replacement therapy to address the underlying pathophysiology of Fabry disease has focused attention on the need for comprehensive, multidisciplinary evaluation and management of the multi-organ system involvement. In anticipation of evidence-based recommendations, an international panel of physicians with expertise in Fabry disease has proposed guidelines for the recognition, evaluation, and surveillance of disease-associated morbidities, as well as therapeutic strategies, including enzyme replacement and other adjunctive therapies, to optimize patient outcomes.

Thyroid nodule evaluation: what have we really learned from recent clinical guidelines?

Biomed Pharmacother. 2006 Sep;60(8):393-5

Authors: Carpi A, Mechanick JI, Nicolini A, Rubello D, Iervasi G, Bonazzi V, Giardino R

Recent guidelines for the evaluation of thyroid nodules clarify the diagnostic algorithm while also reporting important differences. The performance of fine needle aspiration (FNA) for cytological examination follows serum TSH determination and thyroid ultrasonography. Thyroid scintigraphy is recommended following a low TSH value and/or FNA yielding an indeterminate follicular cytology. The use of thyroid ultrasonography is the source of some controversy: though it is recommended as a principal first test, its real-time use to guide FNA ranges from routine to only following an FNA yielding an inadequate or nondiagnostic cytological result. In clinical practice, the proportion of physicians utilizing ultrasonography, scintigraphy and FNA varies and frequently deviates from recommended guidelines. The development of guidelines is necessary to bring about consistency and optimization to the diagnostic work-up of thyroid nodules. It is likely that novel diagnostic procedures, such as molecular markers, large needle aspiration biopsy and thyroid imaging with tracers beyond conventional radioactive iodine or (99m)Tc pertechnetate, will lead to improved performance and implementation of guidelines.
