The agreement between self-assessment and clinician assessment of dry eye severity.

PURPOSE: The purpose of this analysis was to measure the degree of agreement between clinicians' assessment and subjects' self-assessment of dry eye severity in a cross-sectional, observational dry eye study. A secondary purpose was to identify the role of gender and age in that concordance. METHODS: In a cross-sectional observational study, 162 dry eye subjects and 48 controls were recruited from clinical databases of ICD-9 codes in 6 clinical sites. Before examination, subjects gave a global self-assessment of the severity of their dry eye from "none" to "extremely severe." After a clinical examination that included dry eye tests, the clinician discussed the subjects' symptoms and then gave global clinician assessment of dry eye from "none" to "severe." We measured the degree of agreement in these global measures. RESULTS: Although the correlation and agreement between clinician and self-assessment was significant (r = 0.720, P = 0.000; weighted K = 0.471; 95% CI = 0.395, 0.548; P = 0.000), the clinician assessment underestimated the severity in 40.9% of the subjects by at least 1 grade compared with the subjects' self-assessment. Over 54% of subjects over age 65 and 43% of the female subjects had their condition underestimated by the clinician (P < 0.05). CONCLUSIONS: Clinicians often relatively underestimated the severity of the subjects' self-assessment of dry eye in this clinical study, especially among the elderly and women. Eye care practitioners need better, more quantitative tools for the assessment of ocular surface symptoms to improve the concordance in severity assessment and to meet the needs of this symptomatic patient population by offering them appropriate treatments.

Computer-Assisted Retrospective Clinical Activities Statistics (CARCAS) Program.

Clinical pharmacy services have been demonstrated to have a positive impact on patient care in the hospital setting. Accurate and complete documentation of interventions aimed at improving drug use is essential to assess workload characteristics, determine the impact of pharmacist activities, justify current programs and predict future clinical staffing requirements. The need for an improved system of collecting and analyzing clinical workload statistics led to the development of a Computer-Assisted Retrospective Clinical Activities Statistics (CARCAS) Program in our department. Using a pre-defined clinical activity coding system, pharmacist activities were efficiently documented on a daily basis using an existing distributional computer system. Training requirements and data entry time were minimal. The CARCAS Program appeared to capture more clinical pharmacist activities than the earlier manual system. The flexibility of the CARCAS Program should permit adaptation to other hospitals with similar computer systems regardless of the nature of their clinical programs.

Comparison of the Elixhauser and Charlson/Deyo methods of comorbidity measurement in administrative data.

BACKGROUND: Comorbidity risk adjustment methods have been used widely with administrative data, and the Charlson/Deyo method is perhaps the most commonly used in the literature. However, a new method defined by Elixhauser et al. has been introduced recently and could be superior, although it has not been validated widely. OBJECTIVES: We compared the Charlson/Deyo and Elixhauser methods using Canadian administrative data on patients with myocardial infarction (MI). RESEARCH DESIGN: We conducted a historical cohort study. SUBJECTS: We used administrative hospital discharge data from a large Canadian city for all cases with acute MI coded as most responsible diagnosis between January 1, 1995, and March 31, 2001. MEASURES: We used each of the 2 methods to define comorbidity variables based on the International Classification of Diseases, 9th Revision, Clinical Modification codes present in each case record. We then compared 2 models predicting in-hospital mortality based on presence or absence of the variables defined by each of the methods. Frequency tables were produced and c-statistics and changes in -2 log likelihood (-2LogL) were calculated. We also visually assessed model performance by plotting observed and expected percentages of death for increasing risk categories defined by the 2 models. RESULTS: The Elixhauser model outperformed the Charlson/Deyo model in predicting mortality, with higher c-statistic values (0.793 vs. 0.704). Superior performance of the Elixhauser method is confirmed when plotting the expected and observed risks of death across groupings of increasing risk, in which the Elixhauser method yields a wider range of predicted and observed probabilities of death across groupings (2.5%-33%) than does the Charlson/Deyo method (5%-25%). CONCLUSIONS: The Elixhauser comorbidity measurement method performs better than the widely used Charlson/Deyo method in the Canadian acute MI cases studied.

An approach to the definition of periodontal disease syndromes by cluster analysis.

Clinical syndromes of 22 untreated patients with advanced destructive periodontal disease were analyzed using cluster analysis. Clinical characteristics coded for each patient included age, sex, measures of gingival inflammation, plaque, suppuration, pocket depth, attachment level, extent and pattern of bone loss, rate of change in pocket depth, and correlation coefficients between certain clinical measurements. Microbiologic features included darkfield enumeration of 10 morphologically distinct forms of organisms which were removed from the three sites showing the most advanced destruction in each patient, as well as viable counts of specific microbial groups from the same teeth using elective and selective media. Serum antibody levels were determined by the ELISA technique to 13 species of subgingival microorganisms. The Gower coefficient was used to estimate similarity between patients and clusters were formed using an average unweighted linkage sort. Three distinct patient clusters were observed with greater than 70% average intra-cluster similarity. One subject did not fall into any of the patient clusters. The features which defined and differentiated the clusters were found to include age of subject, extent and patterns of bone loss, percent of sites showing change in pocket depth and attachment level, percent of small motile rods, intermediate spirochetes and fusiforms and serum IgG levels against Bacteroides gingivalis, Selenomonas sputigena and a Wolinella strain.

The Cooperative Breast Cancer Tissue Resource: archival tissue for the investigation of tumor markers.

Investigators continue to search for reliable markers of prognosis of breast cancer. For many analyses, laboratory techniques permit the use of archival paraffin-embedded tissue collected years previously and readily linked to clinical and follow-up information. Laboratory investigators have often expressed the need for such a tissue resource. We have developed a publicly available resource of archival breast cancer specimens. The pathological material has been collected and reviewed by investigators at four institutions and currently includes breast cancer specimens from more than 9300 cases. Institutional pathologists reviewed slides and blocks using a common protocol and coding scheme. Clinical information and details of follow-up came from data routinely collected by the institutions' cancer registries. Coded data are maintained centrally in a single database. A subset of the data may be searched on the World Wide Web to determine the availability of cases with specified characteristics. The material collected by this Cooperative Breast Cancer Tissue Resource is generally representative of breast cancer diagnosed in community hospital settings in the United States. Seventy-two percent of the living cases have been followed for at least 5 years, and follow-up status is updated regularly. Interested laboratory investigators may apply to the Resource for the use of these tissues. This Resource is proving valuable to laboratory investigators who require large numbers of specimens for validation studies of prognostic markers of breast cancer.

Brain profiling and clinical-neuroscience.

The current psychiatric diagnostic system, the diagnostic statistic manual, has recently come under increasing criticism. The major reason for the shortcomings of the current psychiatric diagnosis is the lack of a scientific brain-related etiological knowledge about mental disorders. The advancement toward such knowledge is further hampered by the lack of a theoretical framework or "language" that translates clinical findings of mental disorders to brain disturbances and insufficiencies. Here such a theoretical construct is proposed based on insights from neuroscience and neural-computation models. Correlates between clinical manifestations and presumed neuronal network disturbances are proposed in the form of a practical diagnostic system titled "Brain Profiling". Three dimensions make-up brain profiling, "neural complexity disorders", "neuronal resilience insufficiency", and "context-sensitive processing decline". The first dimension relates to disturbances occurring to fast neuronal activations in the millisecond range, it incorporates connectivity and hierarchical imbalances appertaining typically to psychotic and schizophrenic clinical manifestations. The second dimension relates to disturbances that alter slower changes namely long-term synaptic modulations, and incorporates disturbances to optimization and constraint satisfactions within relevant neuronal circuitry. Finally, the level of internal representations related to personality disorders is presented by a "context-sensitive process decline" as the third dimension. For practical use of brain profiling diagnosis a consensual list of psychiatric clinical manifestations provides a "diagnostic input vector", clinical findings are coded 1 for "detection" and 0 for "non-detection", 0.5 is coded for "questionable". The entries are clustered according to their presumed neuronal dynamic relationships and coefficients determine their relevance to the specific related brain disturbance. Relevant equations calculate and normalize the different values attributed to relevant brain disturbances culminating in a three-digit estimation representing the three diagnostic dimensions. brain profiling has the promise for a future brain-related diagnosis. It offers testable predictions about the etiology of mental disorders because being brain-related it lends readily to brain imaging investigations. Being presented also as a one-point representation in a three-dimensional space, multiple follow-up diagnoses trace a trajectory representing an easy-to-see clinical history of the patient. Additional, more immediate, advantages involve reduced stigma because it relaters the disorder to the brain not the person, in addition the three-digit diagnostic code is clinically informative unlike the DSM codes that have no clinical relevance. To conclude, brain profiling diagnosis of mental disorders could be a bold new step toward a "clinical-neuroscience" substituting "psychiatry".

The frequency of complications associated with the use of multiple-dose activated charcoal.

STUDY OBJECTIVE: The objective of this study was to determine the frequency of complications associated with the use of multiple-dose activated charcoal. METHODS: The study population was drawn from 8 tertiary care hospitals in 4 North American cities. Medical records of all inpatients between March 1993 and March 1998 with a discharge diagnosis of poisoning (International Classification of Diseases, 9th edition, Clinical Modification codes 960-989.9) were reviewed to select patients who had received multiple-dose activated charcoal (defined as > or =2 doses administered within 12 hours). Medical records of patients who received multiple-dose activated charcoal were reviewed for patient demographics and clinical information regarding the occurrence of pulmonary aspiration, gastrointestinal obstruction, hypernatremia, hypermagnesemia, corneal abrasion, and other complications associated with the use of multiple-dose activated charcoal. RESULTS: We reviewed 6,258 medical records, identifying 878 patients who received multiple-dose activated charcoal. We judged 5 (0.6%; 95% confidence interval [CI] 0.1% to 1.1%) patients to have had clinically significant pulmonary aspiration and none (0%; upper 95% CI 0.3%) to have had gastrointestinal obstruction. None of the patients with pulmonary aspiration died or had residual sequelae recorded. Hypernatremia (peak serum sodium >145 mEq/L [145 mmol/L]) was documented in 53 (6.0%; 95% CI 4.4% to 7.6%) patients, of whom 5 (0.6%; 95% CI 0.1% to 1.1%) had a serum sodium concentration of greater than 155 mEq/L (155 mmol/L). Hypermagnesemia (peak serum magnesium >2.5 mg/dL [1.0 mmol/L]) was documented in 27 (3.1%; 95% CI 2.0% to 4.2%) patients, of whom 3 (0.3%; 95% CI 0.1% to 1.0%) had peak values that were greater than 3.75 mg/dL (1.5 mmol/L). One patient had a corneal abrasion (0.1%; 95% CI 0% to 0.6%). No other complications were identified. CONCLUSION: Clinically significant complications associated with the use of multiple-dose activated charcoal occur infrequently.

Common medical terminology comes of age, Part One: Standard language improves healthcare quality.

It has become abundantly clear that standards of recording clinical terms in human-readable, computer-processable format are indispensable. Controlled medical terminology is the missing link in health information standards (in fact, medical terminology can be viewed as the mother of all standards); its absence interferes with the business of healthcare and impedes the core processes of healing and maintaining health. Medicine has lacked the controlled common medical vocabulary that would enable universal sharing of data at the point of care and ensure reliable information for determining health intervention effectiveness. Simple clinical and code content alone has proven insufficient for healthcare enterprises to successfully manage the terminology problem; the "lexical runtime engine," formerly called a vocabulary server (VOSER), which manages the vocabulary ontology and serves up the relevant vocabulary to users of applications in the clinical environment, has recently become a reality.

Over- and undercontrolled clinic referral problems of Jamaican and American children and adolescents: the culture general and the culture specific.

Child behavior problems and corresponding clinic referral patterns may be significantly influenced by cultural factors. Prevailing values and childrearing practices within a culture may discourage development of some child problems while fostering others. We explored this possibility, focusing on clinic referral problems of two different societies: (a) Jamaica, where the Afro-British culture discourages child aggression and other undercontrolled behavior and possibly fosters inhibition and other overcontrolled behavior, and (b) the United States, where undercontrolled child behavior is seemingly more generally accepted. We coded clinic-referred problems listed by parents of Jamaican and American youngsters (N = 720). Cross-cultural differences were striking: Overcontrolled problems were noted more often for Jamaican than American youngsters, whereas the converse was true for undercontrolled problems. These and other findings suggest that factors such as culture and sex may be linked to substantial differences in the problems for which youngsters of different countries are treated in clinics.

The MCFONTZL classification system for soft-tissue injuries to the face.

A review of the literature and case records reflected a need for the development of a clinically applicable assessment scheme and classification system for soft-tissue laceration injuries to the face. Herein, a systematic approach for assessing facial lacerations is proposed based on location, depth of penetration, branching, directionality, size, presence of soft-tissue defect, and translation of such injuries into the current procedural terminology (CPT) code. Moreover, a new classification system for facial laceration injuries is presented that may serve as the basis for simplification of current billing codes. Prospective clinical application of this classification system may lead to standardization of facial injury assessment and improvement in the incomplete and inconsistent patient record. This system will establish a reliable database that may identify factors in soft-tissue injuries that contribute to poor aesthetic results or secondary functional deformities. These data will lead to the modification of established treatment plans.

A multicenter, retrospective pilot study of resource use and costs associated with severity of disease in glaucoma.

OBJECTIVE: To examine resource consumption and the direct costs of treating glaucoma at different disease severity levels. DESIGN: Observational, retrospective cohort study based on medical record review. PARTICIPANTS: One hundred fifty-one records of patients with primary open-angle or normal-tension glaucoma, glaucoma suspect, or ocular hypertension (age > or =18 years) were randomly selected from 12 sites in the United States and stratified according to severity based on International Classification of Diseases, Ninth Revision, Clinical Modification codes. Patients had to have been followed up for a minimum of 5 years. Patients with concomitant ocular disease likely to affect glaucoma treatment-related resource consumption were excluded. METHODS: Glaucoma severity was assessed and assigned using a 6-stage glaucoma staging system, modified from the Bascom Palmer (Hodapp-Anderson-Parrish) system. Clinical and resource use data were collected from the medical record review. Resource consumption for low-vision care and vision rehabilitation was estimated for patients with end-stage disease based on specialist surveys. For each stage of disease, publicly available economic data were then applied to assign resource valuation and estimate patient-level direct costs from the payer perspective. MAIN OUTCOME MEASURES: Average annual resource use and estimated total annual direct cost of treatment were calculated at the patient level and stratified by stage of disease. Direct costs by specific resource types, including ophthalmology visits, glaucoma surgeries, medications, visual field examinations, and other glaucoma services, were also assessed. RESULTS: Direct ophthalmology-related resource use, including ophthalmology visits, glaucoma surgeries, and medication use, increased as disease severity worsened. Average direct cost of treatment ranged from $623 per patient per year for glaucoma suspects or patients with early-stage disease to $2511 per patient per year for patients with end-stage disease. Medication costs composed the largest proportion of total direct cost for all stages of disease (range, 24%-61%). CONCLUSIONS: The study results suggest that resource use and direct cost of glaucoma management increase with worsening disease severity. Based on these findings, a glaucoma treatment that delays the progression of disease could have the potential to significantly reduce the health economic burden of this chronic disease over many years.

Using n-gram method in the decomposition of compound medical diagnoses.

OBJECTIVE: Our goal in this study was to find an easy to implement method to detect compound medical diagnosis in Hungarian medical language and decompose them into expressions referring to a single disease. METHODS: A corpus of clinical diagnoses extracted form discharge reports (3,079 expressions, each of them referring to only one disease) was represented in an n-gram tree (a series of n consecutive word). A matching algorithm was implemented in a software, which is able to identify sensible n-grams existing both in test expressions and in the n-gram tree. A test sample of another 92 diagnoses was decomposed by two independent humans and by the software. The decompositions were compared with measure the recall and the precision of the method. RESULTS: There was not full agreement between the decompositions of the humans, (which underlines the relevance of the problem). A consensus was arrived in all disagreed point by a third opinion and open discussion. The resulting decomposition was used as a gold standard and compared with the decomposition produced by the computer. The recall was 82.6% the precision 37.2%. After correction of spelling errors in the test sample the recall increased to 88.6% while the precision slightly decreased to 36.7%. CONCLUSION: The proposed method seems to be useful in decomposition of compound diagnostic expressions and can improve quality of diagnostic coding of clinical cases. Other statistical methods (like vector space methods or neural networks) usually offer a ranked list of candidate codes either for single or compound expressions, and do not warn the user how many codes should be chosen. We propose our method especially in a situation where formal NLP techniques are not available, as it is the case with scarcely spoken languages like Hungarian.

Patterns of sleep-related medications prescribed to elderly outpatients with insomnia in Taiwan.

OBJECTIVE: To explore prescription patterns and determinants of sleep-related medications prescribed to elderly outpatients with insomnia in Taiwan. METHODS: This cross-sectional study was based on 2001 annual outpatient claims data released by the Bureau of National Health Insurance in Taiwan. The claims data of each physician consultation were extracted and merged in one claim file. International Classification of Diseases (9th Edition)-Clinical Modification codes, patient's demographics, physician's specialty, the medical institution code and the content of pharmaceutical prescription constituted a file. Patients were included if they were: (i) > or =65 years of age; and (ii) coded as having 'insomnia'. RESULTS: Elderly insomniacs made up 216,994 of the 1,000,193 outpatient claim files we surveyed. Patients had a mean age of 74.33 years, and the sex distribution was nearly equal. Based on the data above, 11.14% of the elderly had been diagnosed as having 'insomnia' for the year 2001. This population preferred primary-care clinics over hospital-ambulatory departments; patients most frequently sought medical help from internal medicine specialists. The most popular sleep medication was lorazepam, followed by zolpidem. The first-choice off-label drug used to treat insomnia was trazodone. Hypnotics, sedatives and anxiolytics were prescribed 12.6 times more frequently than off-label used drugs. When treating insomnia with an off-label drug, physicians usually prescribed a therapeutic dosage much lower than that recommended in the package insert. Choice of sleep medication and off-label drug were most often influenced by physician specialty. Off-label prescriptions were common but not prevalent. Choice of hypnotic or sedative-anxiolytic was related to how long the drug acted and how much it cost; choice of off-label drug was related to physicians' familiarity with specific drugs and patients' characteristics. Concomitant anxiety or depression was significantly associated with higher consumption of hypnotics. CONCLUSIONS: Benzodiazepines and newer non-benzodiazepine hypnotics are still the most frequently used drugs for treating insomnia in the elderly in Taiwan. Elderly patients with concomitant anxiety or depression consumed more hypnotics. Further studies conducted over several years are needed to identify trends in the pharmacological treatment of insomnia.

Does seropositivity for Helicobacter pylori antibodies increase outpatient costs for gastric and duodenal ulcer or inflammation?

BACKGROUND: Helicobacter pylori is regarded as an important cause of both peptic ulcer and chronic gastritis. In particular, seropositivity is highest in patients with duodenal ulcer. No studies have determined whether there are differences in the direct medical costs associated with gastric/duodenal ulcer or inflammation, between seropositive and seronegative patients. OBJECTIVE: To examine the relationship between seropositivity for H. pylori and outpatient visits and direct medical costs for gastric/duodenal ulcer or inflammation in Japan from the perspective of the payor and patients. METHODS: Participants were males (n = 653) who worked for an agricultural co-operative in Fukuoka Prefecture, attended an annual health examination (including a written lifestyle and medical survey), belonged to the same health insurance society consistently for 4 years from April 1996 to March 2000, and provided a blood sample. The survey asked about lifestyle, including smoking and drinking, and past medical history. We retrospectively analysed the annual number of outpatient visits per person and outpatient medical cost (Yen, 2000 values) per person for visits relating to gastric or duodenal ulcer or inflammation using International Classification of Diseases (9th edition) -- Clinical Modification codes. We assessed for potential confounding factors using analysis of covariance and the chi-square test. RESULTS: The annual outpatient incidence of disease, the number of visits to physicians, and the medical costs for gastric or duodenal ulcer or inflammation were about 2-fold greater in individuals with antibodies to H. pylori compared with those without antibodies. CONCLUSION: Population-based studies and/or randomised controlled clinical trials that target high-risk groups and account for the unique way in which data are collected in Japan are needed to determine whether medical costs for gastric and duodenal ulcer might be reduced by treating asymptomatic patients who have antibodies to H. pylori.

[The development of an information network for new techniques in clinical microbiology].

In accordance with changes in our life styles and our social and biological environment, the techniques and methods of clinical microbiology must change and develop. New techniques, such as selected zone culture, direct drug susceptibility test, ATP bio-luminescence assay on membrane filter and expiratory gas analysis are among these developments. To ensure equal development among medical laboratories, an information network concerning these new microbiological methods in needed. An enormous quality of information can be contained and managed usefully by a two dimensional bar-code system. Clinical microbiology must not only contribute to clinical medicine but also respond to changes in the social and biological environment, and must include cost effectiveness, and preservation of natural resources. Using the new techniques effectively and introducing automatic systems will facilitate practical, useful and rapid clinical microbiological diagnoses.

Clean intermittent catheterization: safe, cost-effective bladder management for male residents of VA nursing homes.

OBJECTIVES: To compare the safety and cost of clean versus sterile intermittent bladder catheterization in male nursing home residents. To provide evidence to support the hypothesis that intermittent catheterization is a valid, alternative method of bladder management in male residents of long-term care in whom urinary retention is a documented problem. DESIGN: Randomized clinical trial. SETTING: Three long-term care sites having predominantly male populations. PARTICIPANTS: Eighty male veterans, residents of three long-term care facilities, ranging in age from 36 to 96 years with a mean age of 72. INTERVENTIONS: Standardized procedures for clean and sterile intermittent catheterization (IC) were implemented by staff nurses at each site. Patients were randomized into clean and sterile IC groups. Nursing time and catheterization equipment usage were recorded using bar code readers. Clinical data were collected from the medical chart. Treatment of urinary tract infection was prescribed by the medical personnel responsible for each individual resident. MEASUREMENTS: We compared the number of treatment episodes for symptomatic bacteriuria between groups randomized to receive either clean or sterile intermittent catheterization. Laboratory analysis of blood and urine was done on predetermined days. Control variables were research site and patient history of urinary tract infection within the last 6 months. A cost comparison of nursing time and equipment usage for the two catheterization techniques was also performed. RESULTS: No significant differences were found between clean and sterile groups with regard to number of treatment episodes, time to first infection, type of organism cultured, or cost of antibiotic treatment. The cost of sterile technique was considerably higher both in terms of nursing time and supplies. CONCLUSIONS: Findings from this study demonstrate that clean technique intermittent catheterization is a safe and cost-effective bladder management technique with male, nursing home residents, despite the frailty of this high risk population. An annual savings of approximately $1460 per patient in nursing time and catheterization supplies could be anticipated if a patient were catheterized an average of four times per day substituting clean IC technique for sterile IC technique.

Assessment of the scope and quality of clinical practice guidelines in lung cancer.

STUDY OBJECTIVES: To provide an evidence-based background for developing the American College of Chest Physicians (ACCP) lung cancer guidelines, a systematic review of the literature was performed to identify published lung cancer guidelines and evaluate their quality. DESIGN, SETTING, AND PARTICIPANTS: A systematic search was performed for relevant literature from MEDLINE, Cancerlit, CINAHL, HealthStar, the Cochrane Library, and the National Guidelines Clearinghouse published from January 1989 to July 2001. MEASUREMENT AND RESULTS: From 369 citations, 51 relevant guidelines were identified. Each guideline was evaluated by at least four reviewers using the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument and was coded for clinical topics covered. The recommendations included in each guideline also were abstracted. Of the 51 guidelines evaluated, 27 (53%) were evidence-based. Clinical topics identified by the ACCP for their guideline effort each were represented by at least one existing guideline. Of the 880 clinical recommendations abstracted from the guidelines, only 253 (29%) were evidence-based. The AGREE instrument rates guidelines along six domains. As a group, the guidelines performed well in the scope and purpose domain, with only six guidelines (12%) scoring < 50%. For the remaining domains, however, the guidelines did not perform as well, as follows: for stakeholder involvement, 41 guidelines (80%) scored < 50%; for rigor of development, 29 guidelines (57%) scored < 50%; for clarity and presentation, 17 guidelines (33%) scored < 50%; for applicability, 46 guidelines (90%) scored < 50%; and for editorial independence, 47 guidelines (92%) scored < 50%. After considering the domain scores, the reviewers recommended only 19 of the guidelines (37%). CONCLUSIONS: All major clinical lung cancer topics are covered by at least one guideline, but no single guideline addresses all areas. Furthermore, although existing guidelines may accurately reflect clinical practice, most performed poorly when evaluated for quality. Future guideline efforts that address each item of the AGREE instrument would add substantially to the literature.
