Utility of repeat brain imaging in stroke

PURPOSE: To determine the utility of repeat brain imaging in patients with stroke. METHODS: We reviewed the medical records of 98 consecutive patients in whom stroke was diagnosed between January 1 and December 31, 1991. We noted the number of brain scans performed, the indications cited, and whether repeat imaging changed the therapeutic decisions or final diagnosis. RESULTS: Ninety-eight patients underwent 221 procedures, with 123 repeat imaging studies (98 CT scans and 25 MR images). Sixteen patients had only one scan; 51 had two, and 31 had three or more. Indications for repeat imaging were explicitly documented in 62 (50%) of 123 repeated scans and inferred in another 41 (33%). In 20 (16%), no definite indication could be determined. Indications included lack of acute abnormal imaging findings on the initial scan (n = 48, 39%); compliance with stroke research protocol (n = 11, 9%). In none of the 82 patients did the repeated scan change the diagnosis; therapy was changed in only two (2%) of 82 patients (aspirin was discontinued). CONCLUSIONS: Repeat imaging in patients rarely results in changes in the initial diagnosis or the therapeutic plan; indications for repeat imaging are frequently not clearly stated; in certain groups of patients with stroke, repeat imaging may not be useful.     

Referral of patients with polyneuropathy by the family physician: influence of type of symptoms but not of age

OBJECTIVE: To investigate the influence of the age of the patient and the nature of a polyneuropathy on the referral behaviour of general practitioners (GPs). DESIGN: Written questionnaire sent to GPs regarding paper case records of polyneuropathy. SETTING: University Hospital Utrecht, the Netherlands. METHODS: 1590 GPs were asked about their differential diagnosis regarding a paper case record of a patient with polyneuropathy. There were six case records, differing in age (53, 64 and 73 years) and nature of the disease (sensory or sensorimotor polyneuropathy). The GPs were divided into six groups with similar demographic characteristics and type of practice. To avoid focus on polyneuropathy, all GPs also received questions about three other neurological cases (amaurosis fugax, radicular syndrome and vasovagal collapse). RESULTS: The mean response of the questionnaire was 54% (n = 844). Most GPs diagnosed the polyneuropathy (analysis of variance; p < 0.0001). The age of the patient did not influence the diagnosis nor the referral behaviour. At least 73% of the patients with a sensory and 81% of the patients with a sensorimotor polyneuropathy were referred to neurologists for further investigations (chi(2)-test; p < 0.05). CONCLUSION: At least 73% of the GPs referred a patient with polyneuropathy to a neurologist; patients with muscle weakness were referred more often than patients with only sensory disturbances. Referral was not influenced by the age of the patient.     

Prevalence and recognition of anxiety syndromes in five European primary care settings. A report from the WHO study on Psychological Problems in General Health Care

BACKGROUND: This study explored the prevalence, socio-demographic characteristics and severity of different anxiety syndromes in five European primary care settings, as well as medical help-seeking, recognition by general practitioners (GPs) and treatment prescribed. METHOD: The data were collected as part of the WHO study on Psychological Problems in General Health Care. Among 9714 consecutive primary care patients, 1973 were interviewed using the Composite International Diagnostic Interview. Reason for contact, ICD-10 diagnoses, severity and disability were assessed. Recognition rates and treatment prescribed were obtained from the GPs. RESULTS: Anxiety syndromes, whether corresponding to well-defined disorders or to subthreshold conditions, are frequent in primary care and are associated with a clinically significant degree of severity and substantial psychosocial disability. Their recognition by GPs as well as the proportion treated are low. CONCLUSIONS: Since people with subthreshold anxiety show a substantial degree of disability and suffering, GPs may consider diagnostic criteria to be insufficient. However, their awareness of specific definitions and treatment patterns for anxiety disorders still needs a lot of improvement both for patients' well-being and for the cost resulting from non-treatment.     

Referral and diagnosis of common rheumatic diseases by primary care physicians

OBJECTIVE: To describe primary care patterns of referral and diagnoses of patients with rheumatic diseases referred to rheumatologists. METHODS: The medical records of all consecutive patients referred in 1994 by >300 primary care physicians to two rheumatologists at an academic centre were reviewed. The referring physician diagnosis was compared with the rheumatologist's diagnosis. Sensitivity, specificity and predictive values of primary care diagnoses were estimated using the rheumatologist diagnosis as the 'gold standard'. SETTING: University-based rheumatology out-patient clinic. RESULTS: Over half of the patients referred had a rheumatologist diagnosis of soft-tissue rheumatism or a spinal pain syndrome. Three hundred and forty-seven patients (49%) had a primary care diagnosis of a defined rheumatic disease. Of these, 142 (41%) of the primary care diagnoses were subsequently modified by the rheumatologist. The highest agreement between primary care physician and rheumatologist was observed for crystal-induced arthritis (kappa = 0.86), and the lowest agreement for polymyalgia rheumatica (kappa = 0.39) and systemic lupus (kappa = 0.46). Sensitivity was lowest for a primary care diagnosis of fibromyalgia (48%) and highest for ankylosing spondylitis (94%). Positive predictive values were generally low, in particular for systemic lupus erythematosus (33%) and polymyalgia rheumatica (30%). CONCLUSION: Most patients referred to an academic rheumatology centre had soft-tissue rheumatism or other pain syndromes. In general, diagnostic agreement between rheumatologists and primary care physicians was low. Increased emphasis on musculoskeletal disorders should be encouraged in medical education to increase the efficiency of rheumatology referrals.     

How common is medical training in palliative care? A postal survey of general practitioners

BACKGROUND: General practitioners (GPs) have a central role in palliative care, yet research continues to reveal room for improvement in symptom control at home. There is a need to evaluate how well-prepared GPs are for this task of caring for the dying at home. AIM: To evaluate the training in palliative care GPs have received throughout their careers. METHOD: Postal survey of 450 randomly selected East Anglian GP principals, investigating training in five areas of palliative care (pain control, control of other symptoms, communication skills, bereavement care, use of syringe driver), as clinical students, junior hospital doctors, GP trainees (registrars), and GP principals. RESULTS: A response rate of 86.7% was obtained. While GPs were clinical students, training was uncommon, (32% reported no training in pain control, and 58% no training in bereavement care), although there has been a significant increase in more recent years. Training as junior doctors was particularly uncommon (over 70% report no training in communication skills or bereavement care); there was some evidence of an increase in more recent years. During the GP trainee year, training was much more common. For GP principals, most areas had been covered, although over 20% reported no training in communication skills and bereavement care. During the community-based years as trainee and principal, training was significantly more common than during the hospital-based years of training as clinical student and junior doctor. CONCLUSIONS: There is a continuing need for medical education in palliative care. Particular attention should be paid to the basic medical education of clinical students and the training of junior doctors, especially regarding communication skills and bereavement care.     

North Carolina stroke prevention and treatment facilities survey: rtPA therapy for acute stroke

BACKGROUND and PURPOSE: North Carolina is situated in the "stroke belt" region of the United States, an area of the country with a particularly high incidence of cerebrovascular disease. The North Carolina Stroke Prevention and Treatment Facilities Survey was carried out to determine the availabilities of a variety of stroke prevention and treatment services throughout the state. The purpose of the present study was to determine how widely recombinant tissue-type plasminogen activator (rtPA) has been adopted for the treatment of patients with acute ischemic stroke and to determine the characteristics of the medical facilities in the state offering this therapy. METHODS: A single-page survey was mailed to the medical center directors of each inpatient medical facility in North Carolina. Data collected included questions related to the availability of selected basic and advanced diagnostic tests and procedures, stroke prevention and treatment programs and services (community stroke awareness program, acute stroke identification program, acute stroke team, stroke rtPA protocol, stroke care map, neurologist), and facilities (Stroke Acute Care Unit or equivalent). RESULTS: Responses were obtained from all 125 inpatient medical facilities in North Carolina. rtPA stroke protocols were adopted in 54 facilities located in 46 of the state's 100 counties. Seventy-four percent of the state's population resides in counties with hospitals providing rtPA treatment. Compared with facilities not offering rtPA, those with rtPA protocols more commonly sponsored stroke community awareness programs (41% versus 17%, P=0.003) and more frequently had an organized stroke team (31% versus 8%, P=0. 001), used stroke care maps (56% versus 17%, P<0.001), had rapid stroke identification programs (33% versus 6%, P<0.001), or had a Stroke Acute Care Unit or its equivalent (33% versus 7%, P<0.001). Neurologists were available in 78% of the facilities offering rtPA compared with 38% in facilities without rtPA protocols (P<0.001). CONCLUSIONS: These data show that this new therapy for ischemic stroke is potentially available to a high proportion of the state's citizens based on their county of residence. However, other services that may improve outcomes and reduce stroke-related costs (eg, stroke teams, stroke units, care maps) are not being widely used, even in centers providing treatment with rtPA. The simple methodology used in this study is potentially applicable in other states and permits targeting of selected centers for development of stroke treatment capabilities.     

The management of dental problems presenting to an accident and emergency department

Patients with dental diagnoses, not necessarily traumatic, often present to accident and emergency departments and general medical practitioners. Few doctors have received much, if any, education in the management of these patients. A 6 month prospective study revealed 107 patients (0.3% of new attenders) attending the accident and emergency department of Glasgow Royal Infirmary. Only 19 of these had suffered trauma. Medical staff in the department were only rarely able to make any diagnosis, and management of these patients took place on an empirical, symptomatic basis. Management could be improved by better education of medical students and doctors. Use of an algorithm may be appropriate.     

Comparative effects of increased extracellular potassium and pacing frequency on the class III activities of methanesulfonanilide IKr blockers dofetilide, D-sotalol, E-4031, and MK-499

In order to analyze whether the referral system and nature of care exert any effect on the characteristics of patients, subjects aged 60 or above attending three medical centers on the Hong Kong Island between August and December 1990 were studied with respect to their age, sex, and psychiatric diagnosis. Psychiatric diagnoses were made in 98% of subjects at the psychogeriatric assessment service (PAC) (predominantly chronic organic brain syndrome), in 79.6% at the university psychiatric unit (mainly acute psychiatric problems, substance abuse, and deliberate self-harm), and in 20% at the general outpatient clinic (largely sleep and anxiety-related disorders). There was overrepresentation of the very old (above 80) and underutilization of counseling service at PAC. In Hong Kong, the psychogeriatric needs of the very old and of those with minor emotional disturbances associated with aging, retirement, and bereavement deserve reassessment.     

The role of clinical autopsy in monitoring the quality of the clinical diagnosis in an emergency department

OBJECTIVE: A total of 61 autopsies performed in patients died in emergency department of a university hospital were retrospectively analysed and the findings were compared with clinical diagnoses. METHODS: Sensitivity and specificity of the clinical diagnoses and the correction of medical procedures were measured. The influence of age and sex of patients was analyzed using Fisher's exact test and chi-square-test. RESULTS: The most common causes of death were cardiovascular diseases (52.46%). Autopsy showed unexpected major findings in 44.26% of cases. Major discrepancies between the autopsy reports and the clinical diagnoses, were present in 26.22% of all cases. Absolute concordance between clinical and autopsy diagnoses was obtained in 44.26% of cases. The major sensitivity of clinical diagnosis was found in cerebrovascular disorders (100%), upper digestive hemorrhage (100%), and acute myocardial infarction (82.35%). The lowest sensitivity was found in malignant tumors (16.66%), hemorrhagic pancreatitis (0%) and bowel infarction (0%). The patient cares were correct in 68.85% of cases. No statistically significant differences were observed in relation to age and sex. CONCLUSIONS: We concluded that autopsy is a useful method for evaluate diagnostic procedures and quality of medical cares in emergency departments.     

NMDA receptor-mediated inspiratory off-switching in pneumotaxic-disconnected cats

BACKGROUND: National morbidity surveys provide valuable data for monitoring the health needs of populations, health policy planning and design of medical curricula. In order to meet a long-standing need for such information in Sri Lanka, a nationwide general practice morbidity survey was conducted for the first time in 1996. OBJECTIVES: We aimed to identify people's needs by determining the reasons for encounter or the demand for care with GPs/family physicians, to illustrate the pattern of morbidity in general practice and to determine the average daily workload of GPs in Sri Lanka. METHOD: A random sample of 75 GPs were requested to complete a Practitioner Profile Questionnaire (PPQ) and to record on an encounter form (EF) the reason/s for encounter (RFE) and problems managed during all consultations on 4 July. Central coding of the RFEs and problems defined was done using the International Classification of Primary Care (ICPC). RESULTS: Forty GPs (53.3%) completed the PPQ, while the EF received a response from 34 (43.3%). The GP profile showed a male to female ratio of 7:1, none below 35 years and none qualified after 1984. The average daily workload was 74. It was estimated that GPs handle at least 26.5% of the primary care morbidity. Children accounted for 32% of consultations. There was a significantly higher proportion of children (P < 0.0001) and of the elderly (P < 0.05) in the consulting population compared with the general population. In 2068 encounters, 3448 RFEs and 2087 problems had been recorded. Respiratory and General chapters included 55% of the RFEs. By ICPC rubrics, 27 of the top thirty RFEs were for common symptoms. In addition to acute illnesses, asthma, hypertension and diabetes as well as preventive care activities were within the top 12 problems managed. CONCLUSIONS: The fact that many common illnesses, chronic diseases and preventive treatments are dealt with in general practice shows the necessity to include family medicine in the undergraduate curriculum of all medical schools. Undergraduate and postgraduate training in family medicine should concentrate more on child care and care of the elderly. Suitable incentives may be necessary to motivate younger doctors to become GPs to meet the medical care needs of the community.     

Accuracy of ICD-9-CM coding for the identification of patients with acute ischemic stroke: effect of modifier codes

BACKGROUND AND PURPOSE: Discharge ICD-9-CM (International Classification of Diseases, 9th Revision, Clinical Modification) codes have been used to identify patients with acute stroke for epidemiological, quality of care, and cost studies. The aim of this study was to determine if the accuracy of the primary ICD-9-CM codes for ischemic stroke is improved by modifier codes and how specific codes reflect stroke subtype diagnoses. METHODS: Available hospital charts for all patients discharged from a single hospital between May 1995 and June 1997 with ICD-9-CM codes 433 (occlusion and stenosis of precerebral arteries), 434 (occlusion of cerebral arteries), or 436 (acute but ill-defined cerebrovascular disease) listed in the first position were reviewed. The primary discharge diagnosis was verified, and a presumed stroke subtype was assigned on the basis of information provided in the medical record. RESULTS: Charts were available for 175 of the 198 identified patients (88%). Of these, 61% had an acute ischemic stroke (code 433, 4%; 434, 82%; 436, 79%) with the remaining patients having other conditions. Of the 130 patients with a modifier code indicating cerebral infarction, 79% had an acute stroke; of the 45 patients with a modifier code indicating an absence of cerebral infarction, 7% had acute stroke (sensitivity, 0.97; specificity, 0.60). The codes with the highest proportions of ischemic stroke cases were 434.11 (embolic occlusion of cerebral arteries with infarction, 85%), 434.91 (unspecified occlusion of precerebral arteries with infarction, 82%), and 436 (79%), with a combined sensitivity of 0.81 and specificity of 0.90. On review, 73% of patients with code 434.11 had embolic strokes, and 47% of those with code 436 had an identified stroke cause. Of patients with code 434.91, 39% had stroke of uncertain cause, 25% "lacunar," 17% atherothrombosis, and 15% embolism. CONCLUSIONS: Despite the use of modifier codes, 15% to 20% of patients with the indicated primary ICD-9-CM codes have conditions other than acute ischemic stroke. Although the proportion of patients with acute stroke increased from 61% to 79% with the use of modifier codes, the inclusion of modifier codes did not have an appreciable effect on the accuracy of the coding if patients with code 433 are excluded. Assignment of presumed ischemic stroke subtype is particularly inaccurate.     

The neurologist profile in Valencian community

We carried out a postal opinion poll among members of the Valencian Neurological Society with the aim of defining the profile of the Neurologist in our region. We received 35 replies (30% answer rate). We can characterize the Neurologist in our region as having been an in-house resident doctor (MIR) in 68.6% of cases, working in the public health service in 80% of cases and in a hospital also in 80% of cases. In all cases (100%) general practitioners (GPs) referred patients to neurologists as opposed to being referred by other possible routes-emergencies, other specialties, the patient him or herself-most neurologists considering patients should come with adequate clinical history (94.3%), medical examination (82.9%) and suspected diagnosis (68.6%). 97.1% expressed the opinion that it is the neurologist who must decide the follow-up for neurological patients. 85.7% think direct access on the part of the neurologist to Doppler techniques is essential and 80% think the same concerning access to neuropathological studies, which contrasts with the meager development of these techniques in our region. About 70% believe Doppler techniques should be performed by the neurologist. 68.6% consider the neurologist should be involved in neurology management with decisive powers. 62.9% said subspecialties are interesting for research and backup, the most necessary of such subspecialties being cerebrovascular pathology, neuromuscular pathology, extrapyramidal pathology and epilepsy. Most neurologists were of the opinion that Neurology should have nothing to do with Psychiatry or Internal Medicine, although there is a need for important relations with Neurophysiology through the setting up of a common organization or of functional units. It was generally though the neurologist should be involved in teaching at all levels. 77.1% agree with the existence of a credit system for continuous assessment in the specialty, most (57.1% considering such a scheme should be optional and performed by the regional scientific societies (40%).     

Determination of 60% or greater carotid stenosis: a prospective comparison of magnetic resonance angiography and duplex ultrasound with conventional angiography

BACKGROUND: Direct access to Magnetic Resonance Imaging (MRI) is becoming available to GPs in the UK, offering major benefits for the improved diagnosis and management of certain clinical conditions. Variations in usage of this service may be large, and effective locally produced guidelines are not currently available. The Department of General Practice is conducting a research programme to develop and evaluate methods to optimize MRI use by GPs. OBJECTIVES: We aimed to describe the current use of MRI by GPs in South Glamorgan; to summarize their reasons for requesting MRI; and to produce criteria to assess the appropriateness of magnetic resonance (MR) scan requests. METHODS: Using the critical incident technique, 25 GPs were interviewed about recent scans requested for patients with knee and lumbar spine complaints. A local panel of primary and secondary care doctors was convened to develop criteria for assessing MR scan requests. RESULTS: Sixty-two scan requests were discussed. Doctors' reasons for requesting MR scans were identified and classified. Reasons for requests included personal, contextual and biomedical variables. Fifteen patients (24%) were managed in primary care following MRI when otherwise they would have been referred. When referrals were made, GPs felt able to reinforce the request and occasionally to direct the patient somewhere more appropriate. The panel reviewed the interview data to produce objective criteria to assess scan requests. The criteria reflect the relative importance of non-biomedical variables in the decision to request MRI. CONCLUSION: The study identified those reasons which are important to GPs when requesting MR scans and the impact of this new technology upon patient management. Interview data have been used to inform locally developed consensus criteria, which will be made available as practice guidelines as the research programme progresses.     

Informatics support to medical diagnosis. General information obtained from a first structured contact with the patient

BACKGROUND: The methods and characteristics of clinical data gathered at the initial steps of development of a computerized system to aid medical diagnosis are reported. The objectives of the study were as follows: to describe the overall method and to set a framework for developing an intellectual model of the medical diagnosis procedure. MATERIAL AND METHODS: A structured medical interview and physical examination using an informatic program on PC compatible portable computers were completed in a sample 1,238 patients attending the outpatient clinics of our institution. Data obtained were compared with information in the patient's medical record taking as reference pattern the record of physicians in charge of the patients. Diagnosis were codified according to WHO International Classification of Diseases (ICD-9-CM). RESULTS: The distribution of symptoms and signs corresponding to the different organs and systems was analyzed. Each subdivision afforded a range of 1.3 to 3.9 abnormal findings per patient. A total of 3,571 diagnoses were codified for the whole group 1,238 patients with a mean (standard deviation) of 3 (2) diagnoses per patient (range 0-12). The distribution of diagnostic groups varied depending on the consideration of the main diagnosis or the concomitant diagnoses that defined the patient's clinical context. The most frequent main diagnoses included tumors, cardiovascular diseases, gastrointestinal disorders, and genitourinary tract diseases. CONCLUSIONS: As shown by results obtained in a sample of 1,238 patients, there is a very complex situation in clinical practice due to the simultaneous occurrence of several clinical patterns. This finding should be taken into account when developing clinical decision making support systems. The use of a structured medical interview or a structured and standard medical visit may be an adequate tool to clarify this matter and to contribute to standardization of clinical concepts and situations.     

The general practitioner, the drug misuser, and the alcohol misuser: major differences in general practitioner activity, therapeutic commitment, and 'shared care' proposals

BACKGROUND: The primary care setting has been regarded in government policy and the scientific literature as an ideal setting for the work needed to meet the Health of the Nation drug and alcohol targets. Although studies have pointed to the negative attitudes held by general practitioners (GPs) towards alcohol- and drug-misusing patients, there has been no direct comparison of the work and attitudes of the GP towards these patients. AIM: To compare the work and attitudes of GPs towards alcohol- and drug-misusing patients. METHOD: All GPs in an outer London area (157 doctors) were surveyed, using an eight-page postal questionnaire, collecting clinical and attitudinal data alongside demographics and practice information. A response rate of 52% was achieved. RESULTS: General practitioners reported working with only 3.5 patients drinking above recommended guidelines in the previous four working weeks, and even fewer drug-using patients (0.75). While they viewed the alcohol-misusing patients negatively, the drug misuser elicited substantially more negative attitudes. The primary care setting was seen as appropriate to work with the alcohol-misusing patient but not with drug users. Training and support from local services would encourage substantially more GPs to work with alcohol misusers but not with drug misusers. CONCLUSIONS: Our findings indicate that there are some cautious grounds for optimism that GPs are willing to work with alcohol misusers; however, with regard to drug misusers, we find a GP workforce that is only minimally involved with this group and would not be greatly encouraged by the provision of additional training, support, or incentives. The Health of the Nation targets are not being met, and GPs are not detecting adequate numbers of the patients at whom these targets are aimed. Emphasis has been placed on the role of primary care, but the real achievements that can be made require detection of the less severe drinkers and injecting drug misusers.     

Promotion of neovascularization around hollow fiber bioartificial organs using biologically active substances

Hypertension is common in West Africa and likely to become more common as urbanisation increases. There are at present few facilities for the detection and management of hypertension so the influence it has on overall morbidity and mortality in the population is not clear. The objectives of the study were to assess: (a) renal disease and blood pressure related admissions and deaths among acute medical admissions to Komfo Anokye Teaching Hospital, Kumasi, during an 8-month period; and (b) the burden of renal disease among out-patient hypertensives at the same hospital. Ward admission books were examined in the four acute medical wards to ascertain admission diagnosis and cause of death (two 4-month periods in 1995 and 1996). Clinical assessment (blood pressure, plasma creatinine, proteinuria) was also made of 448 consecutive out-patient hypertensives seen between March 1995 and April 1996. Five hundred and ninety-three (17.9%) of 3317 acute medical admissions were ascribable to a cardiovascular cause (hypertension, heart failure, stroke); 171 (28.8%) of these died. One hundred and sixty-six (5.0%) had renal disease of whom 45 (27.1%) died, usually of end-stage renal disease. Among the 448 hypertensive out-patients, 30.2% (110 out of 365) had a plasma creatinine >140 micromol/l (48 > or = 400 micromol/l) and 25.5% (96 out of 376) had proteinuria. Eighty-nine of the 448 had a diastolic blood pressure > or =115 mm Hg; in this group 38 (42.7%) had a plasma creatinine of >140 micromol/l (and 18 or 20.2% > or =400 micromol/l). In conclusion, cardiovascular and renal disease are important contributors to morbidity and mortality among acute medical admissions to a large city hospital in Ghana. Among out-patient hypertensives renal disease is an important complication, especially in those with the more severe hypertension.     

Medical Records for Building Health Management

Medical records provide essential information for evaluating a patient’s health. Without them, it would be difficult for doctors to make accurate diagnoses. Similar to diagnoses in medical science, building health management also requires building medical records for making accurate diagnoses. At later stages of a building’s life cycle, when the budget is limited, organizations responsible for building repairs and maintenance are unable to digitalize building health diagnoses and keep complete medical records of buildings; as a result, maintenance crews usually cannot fully understand buildings’ overall health conditions and their medical histories, which may result in erroneous diagnoses directly or public safety dangers indirectly. Using the problem-oriented medical record adopted for the medical diagnosis of human diseases, this paper designs a building medical record (BMR), which allows simple electronic archiving, and evaluates its practicability with a case study of school buildings. The purpose of a BMR is to enable maintenance engineers (building doctors), building managers, and contractors of school buildings to have low-cost access to required information for making complete evaluations and maintenance suggestions for buildings.     

Prevalence of mood disorders and utility of the PRIME-MD in patients undergoing radiation therapy

PURPOSE: To validate a short, structured interview procedure that allows practicing oncologists to quickly and reliably identify mood disorders in their patients, and to estimate the prevalence and types of mood disorders in a radiation therapy patient setting, noting relationships between mood disorders and patient characteristics. METHODS: Consecutive, eligible adult patients from the practices of two radiation oncologists were administered the Primary Care Evaluation of Mental Disorders (PRIME-MD) by the treating physician. A subset of these patients was also evaluated with the SCID, administered by trained mental health care personnel. Agreement between the two instruments was examined using the kappa statistic. Prevalence of mood disorders was determined from the PRIME-MD. The significance of relationships between patient characteristics and mood disorders was examined by chi-square and ANOVA analysis, and subsequently by multivariate logistic regression analysis. RESULTS: One hundred twenty-two patients were studied. Fifty-three of these were administered the SCID. Agreement between the two instruments was very good (kappa = 0.70). A diagnosis of a depressive or anxiety disorder by the PRIME-MD was made in 59 of the 122 patients (48%, 95% confidence interval = 39%, 58%). Multivariate analysis showed that a diagnosis of a depressive mood disorder was significantly related to pain intensity and prior history of depression. CONCLUSION: We have demonstrated the validity and feasibility of the PRIME-MD administered by oncologists in making diagnoses of mood disorders. The prevalence of mood disorders in our set of patients undergoing a course of RT was nearly 50%. Future studies should describe the natural history of these disorders, and determine optimal intervention strategies.     

Computer-generated correspondence for patients attending an open-access chest pain clinic

AIM: To determine whether general practitioners (GPs) prefer structured computer-generated or standard dictated outpatient clinic letters. DESIGN: Questionnaire survey of all GPs referring patients to an open-access chest pain clinic at a district general hospital in London. The GPs were asked to compare three twinned examples of structured computer-generated and unstructured dictated letters. RESULTS: Of 93 respondents (response rate 77.5%), 75 (80.6%) preferred the computer-generated letter and 16 (17.2%) preferred the dictated letter (p < 0.0005). The preferred features of the computer-generated letter were its clear presentation, subheadings, and concise information. The computer-generated letter scored significantly higher than the dictated letter: for clarity, mean 8.2 vs 6.5 (p < 0.0005); content, mean 8.5 vs 6.9 (p < 0.0005); and readability, mean 8.2 vs 6.8 (p < 0.0005). The GPs in the survey considered a mean delay of 3.4 days to be acceptable for receiving the letter from the chest pain clinic. CONCLUSION: GPs prefer structured computer-generated letters to unstructured dictated letters for patients referred to an open-access chest pain clinic. Computer-generated correspondence allows rapid feedback of information to the referring GP, one of the key requirements of open-access clinics.
