Rubella vaccination status and immunity to rubella were studied in 230 "active patients" aged 8 to 22 years in a teaching family practice by means of a chart review and measurement of the rubella antibody titre in a blood sample. Of the 200 patients who submitted a blood sample 161 (80%) were found to be immune, having a rubella hemagglutination-inhibiting antibody titre of 1:16 or greater. Log linear analysis showed that immunity to rubella was independent of a history of rubella, and that 94% of the vaccinated patients versus 74% of the unvaccinated patients (a significant difference; P = 0.007) were immune. In retrospect we estimated that 80% of the study group were protected at the start of the study. After surveillance and follow-up, with vaccination of 27 of the 39 patients identified as susceptible to rubella, this estimated proportion increased to 90%. The study showed that there is nothing to be gained by asking about a history of rubella but that vaccination against this disease is increasing among children aged 5 to 9 years.  相似文献

Six hundred and fifty-three teenagers (aged 11-13 year) living in Siena and its surroundings (Tuscany, Italy) were the sample for serological screening intended to ascertain immunity to rubella. It was found that 324 of the teenagers (49.62%) lacked antibodies and, hence, were unprotected against the infection. Out of the 324 girls, 196 (around 3/5) were vaccinated using live vaccine. Post-vaccinal complications, with clinical signs of rubella infection, were recorded in almost one third of the vaccinees. Virus isolation from the blood was, in every case, not possible after either 10 or 30 days from vaccination. The serological findings, expressed in hemagglutination inhibition antibodies, could be summarized in the following way: (i) antibodies at low titre were found in only eight out of 184 girls (4.35%) ten days after vaccination; (ii) serological conversion was recorded in 187 out of 188 girls (99.47%) 30 days after vaccination; (iii) the titres were moderately high but much lower than those recorded for the natural infection. The results are discussed in the context of their implications for the strategies of rubella vaccination as far as the safety and the effectiveness of the vaccine are concerned, with emphasis on the duration of the protective immunity.  相似文献

OBJECTIVE--To develop and report the results of a system of audit of computer records in general practice. DESIGN--A retrospective audit of records in practices using the same computer system. Information about recorded preventive procedures was collected by sending the same audit program to each practice on floppy disk. Other characteristics of the practices were determined by postal questionnaire. SETTING--Forty five general practices, widely distributed in England and Wales. SUBJECTS--All 430,901 patients registered with the practices. MAIN OUTCOME MEASURES--Within each practice the percentage of patients in specified age groups for whom certain preventive procedures were recorded as having been carried out. These measures were analysed in relation to practice characteristics. RESULTS--Practice characteristics and recording rates for preventive procedures varied over a wide range. Recording rates were higher in practices with computer terminals on every doctor''s desk. Only one practice achieved the new contract target of 90% coverage for recorded primary immunisations, and fewer than two thirds recorded 80% coverage for cervical cytology in the past five years. Practices holding clinics did no better than those without. Smaller partnerships and smaller doctors'' list sizes were associated with better performance. CONCLUSIONS--Centrally programmed audit of computerised records is a feasible method of providing data on a regular basis for epidemiological purposes and for performance review. The fact that practices with smaller list sizes had higher levels of recorded preventive care suggests that the trend towards larger lists promoted by the new contract might militate against the intended effect of better preventive care.  相似文献

Between November 1979 and January 1980 all patients aged 13-21 years who attended a general practice in Glasgow were tested for their immunity against rubella (single radial haemolysis test). All of the women in the sample should have been vaccinated at 13 as part of the rubella vaccination programme, which began in Glasgow in 1971. The programme excludes boys. Of the 77 females and 64 male patients studied, nine (11.7%) and 10 (15.6%), respectively, were susceptible to the infection. For only 34 women was evidence of vaccination documented in the practice records, and three of those either had failed to seroconvert or had antibody below detectable values. Overall there was no significant differences between the proportion of men and women who were susceptible to the disease. The rubella vaccination programme had clearly failed to reduce the number of susceptible women in this practice. Hence the immune state of all girls should be checked at about 15 years of age, so that as many as possible may be rendered immune before they leave school.  相似文献

The records of patients who were registered with general practice in inner London and outer London (both training and non-training practices) were examined for details of blood pressure recordings. A blood pressure recording was found in the past five years in only 22% of the notes of inner London practices but in 43% of notes in outer London practices, there being no difference between training and non-training practices. In 31% of the notes with a blood pressure recording the blood pressure had been raised (greater than or equal to 160/90) at some time: in 62% of these notes for patients aged 65 or more and in 52% of these notes for patients aged under 65 treatment had been given at some time. Thirty eight per cent of patients in the older group and 33% in the younger group were being treated at the time of the survey, thiazides being the most commonly used drugs. Thirty four per cent of all those with a raised blood pressure at some time had a latest recording of under 90 mm Hg diastolic. There seems to be a continuing need for general practitioners to detect and treat hypertension, and it is suggested that general practitioners should consider using systematic case finding for hypertension in their practices.  相似文献

OBJECTIVE--To determine what proportion of health promotion activities reported by the patient is recorded in the general practice notes and to compare these methods of assessing health promotion with audio tape analysis. DESIGN--Secondary analysis of data obtained in a controlled trial of differing appointment lengths. After each consultation the medical record was examined and the patient invited to completed a questionnaire. A subsample of consultations was audio taped. SETTING--Nottinghamshire. SUBJECTS--16 general practitioners from 10 practices. This report includes 3324 consultations with patients aged > or = 17, with data on measurement of blood pressure and advice about smoking and alcohol. RESULTS--Data from questionnaire and medical notes were available for 2281 consultations. Advice on smoking was recorded in the notes in 30.9% of cases in which a patient reported it (for alcohol and measurement of blood pressure, 44.4% and 82.7% of cases respectively). In 516 cases analysis of audio tape and review of records was performed. Advice on smoking was recorded in the patient''s notes in 28.6% of cases in which it was detected on audio tape (for alcohol, 31.1% of cases). In 335 consultations data from audio tape and questionnaire were available. Advice on smoking was reported by patients in 73.9% of cases in which it was detected on audio tape (for alcohol, 75.0% of cases). CONCLUSIONS--Review of the medical record is a reasonably accurate method of assessing measurement of blood pressure in the consultation but would lead to significant underestimation of advice about smoking and alcohol.  相似文献

An examination of the practice notes and attached correspondence of 900 patients aged 30 to 65 years in a random sample of 18 general practice in north west London showed that 340 (47%) of 716 patients consulting in a 10 year period had no blood pressure readings in their records. The blood pressure was equal to or above 160 mm Hg systolic or 95 mm Hg diastolic, or both, in 115 (31%) of those whose blood pressures were recorded; 18 (16%) of these were not followed up. Seventy four patients were being treated for hypertension. Diuretics were the most commonly prescribed drugs. Treatment was started after one blood pressure reading in 34 (46%). Nine of those who had an initial raised blood pressure reading were normotensive on follow up. A further 14 patients had subsequent raised blood pressure readings but were not treated. Sixty one (69%) of the 88 patients with hypertension did not have a blood pressure recording after diagnosis for one or more periods exceeding 12 months. Of 84 hypertensive patients with complete records, 62 (74%) apparently had had no physical examination performed by the general practitioner and 61 (72%) did not seem to have had any investigations initiated by the general practitioners. Fifteen (35%) of 43 patients taking oral contraceptive pills apparently had no blood pressure recordings during the time they were taking these. The results of this study suggest that there are still deficiencies in the detection and management of hypertension in general practice.  相似文献

To test a new approach to detecting and managing hypertension, 34 family practices in southwestern Ontario that comprised 32 124 patients aged 20 to 65 years were randomly assigned in a 5-year study to either undertake a system of care in which a medical assistant oversaw screening and attended to education, compliance and follow-up (experimental group) or continue their usual practices (control group). The 17 physicians in the experimental practices (15 659 patients) were matched with the 17 in the control practices (16 465 patients) according to size of the community, sex, level of practice activity and length of time in practice. Hypertension was defined as at least two diastolic blood pressure readings over 90 mm Hg. More patients in the experimental group than in the control group were screened at least once (91% v. 80%); the former were more likely to have lower systolic blood pressure (p less than 0.02), to be compliant (p less than 0.05) and to be very satisfied with care (p less than 0.01). There were no significant differences between the two groups in the rates of illness and death due to cardiovascular disease for all patients or for hypertensive patients. The unassisted family physician can provide effective care for hypertensive patients. However, minor modifications in the physician''s practices can improve care.  相似文献

The vaccine of choice for rubella vaccination is considered to be RA 27/3, based on frequency of side effects, duration of immunity, antigenic potential and rate of reinfection by wild virus. The most appropriate individuals to be vaccinated are prepubertal schoolgirls and susceptible members of other high-risk groups, and a nationwide immunization program is suggested. Premarital determination of rubella-immune status should be mandatory for all women of childbearing age. A favourable cost/benefit ratio for rubella vaccination seems highly probable. The use of a rubella "fact sheet" to provide education and information for those at risk is strongly recommended.  相似文献

Twenty eight practices carried out a review of patient records for information about preventive procedures on two occasions in 1980 and 1982. We have now undertaken a survey of certain characteristics of the practices in an attempt to demonstrate features associated with effective preventive care. Significant favourable factors are a small list size, the setting up of a formal screening programme for cervical cytology and measuring blood pressure, and few registered patients in social classes IV and V. More successful practices also tend to be training practices, have principals with higher qualifications, and have developed good records organization. Opportunistic screening for cervical cytology and measuring blood pressure was not shown to be more effective than no policy of screening at all.  相似文献

To study continuing medical education 96 out of 101 general practitioners chosen at random from the list held by a family practitioner committee were interviewed. The results provided little evidence of regular attendance at local postgraduate centre meetings, though practice based educational meetings were common. Thirty one of the general practitioners worked in practices that held one or more practice based educational meetings each month at which the doctors provided the main educational content. Performance review was undertaken in the practices of 51 of the general practitioners, and 80 of the doctors recognised its value. The general practitioners considered that the most valuable educational activities occurred within the practice, the most valued being contact with partners. They asked for increased contact with hospital doctors. The development of general practitioners'' continuing medical education should be based on the content of the individual general practitioner''s day to day work and entail contact with his or her professional colleagues.  相似文献

OBJECTIVES--To identify causes for the continuing deficit of rubella immunity in women of childbearing age with a view to further reducing the risk of the congenital rubella syndrome. DESIGN--A questionnaire was sent to the general practitioner and a laboratory follow up study conducted in a one year cohort of women found on screening to have inadequate protection against rubella. SETTING--Virus laboratory of the department of medical microbiology, Aberdeen, serving the health board areas of Grampian, Orkney, and Shetland. PATIENTS--239 women whose concentration of antibodies to rubella virus was either absent or below standard (15,000 IU/l) and whose general practitioner could be contacted to supply a history of infection, immunisation, pregnancy, and antibody testing. MAIN OUTCOME MEASURES--Whether rubella vaccination was given and whether those vaccinated were tested for seroconversion. RESULTS--Only 122 (55%) of the women for whom information was available received the recommended vaccine; only 74 (61%) of these were tested for seroconversion. Oversight was the reason given for not vaccinating 64 (65%) of the women who remained at risk. Women who were pregnant when tested were significantly less likely to receive vaccine (odds ratio 3.36) than women who were not pregnant, and even if vaccinated were less likely to have a follow up antibody test (odds ratio 1.94). CONCLUSION--Once women are identified as being unprotected against rubella they are often overlooked and not vaccinated. Prompting mechanisms aimed at general practitioners, such as the one recently set up in Grampian, should reduce the immunity gap and help to eradicate rubella in pregnancy.  相似文献

OBJECTIVE--To determine whether locally developed guidelines on asthma and diabetes disseminated through practice based education improve quality of care in non-training, inner city general practices. DESIGN--Randomised controlled trial with each practice receiving one set of guidelines but providing data on the management of both conditions. SUBJECTS--24 inner city, non-training general practices. SETTING--East London. MAIN OUTCOME MEASURES--Recording of key variables in patient records (asthma: peak flow rate, review of inhaler technique, review of asthma symptoms, prophylaxis, occupation, and smoking habit; diabetes: blood glucose concentration, glycaemic control, funduscopy, feet examination, weight, and smoking habit); size of practice disease registers; prescribing in asthma; and use of structured consultation "prompts." RESULTS--In practices receiving diabetes guidelines, significant improvements in recording were seen for all seven diabetes variables. Both groups of practices showed improved recording of review of inhaler technique, smoking habit, and review of asthma symptoms. In practices receiving asthma guidelines, further improvement was seen only in recording of review of inhaler technique and quality of prescribing in asthma. Sizes of disease registers were unchanged. The use of structured prompts was associated with improved recording of four of seven variables on diabetes and all six variables on asthma. CONCLUSIONS--Local guidelines disseminated via practice based education improve the management of diabetes and possibly of asthma in inner city, non-training practices. The use of simple prompts may enhance this improvement.  相似文献

OBJECTIVE--To describe the association of ethnic and socioeconomic status with recording of preventive care information by selected general practitioners. DESIGN--Random selection of people aged 20-64 registered with 43 general practitioners. Ethnic and social characteristics of stratified samples were determined at interview in the subject''s home. Recording of preventive information was ascertained from general practitioners'' medical records. SETTING--Inner London borough of Tower Hamlets. SUBJECTS--505 ut of 739 people confirmed as residents at their home address (190 white, 86 black, 112 Bangladeshi, 105 Chinese or Vietnamese, 12 other). MAIN OUTCOME MEASURES--Socioeconomic characteristics, consultation with general practitioner, and recorded preventive activities for ethnic groups. RESULTS--Minority ethnic groups were considerably more disadvantaged than white people and five times more likely to be overcrowded (31% v 6%), three times less likely to own their own home(11% v 37%), twice as likely to be in social classes IV and V (54% v 28%) and less likely to be employed (34% v 63%). There were no significant differences between white, black, Bangladeshi, and Chinese or Vietnamese subjects in recording smoking, blood pressure, alcohol consumption, weight, and height in the general practitioners'' medical records. White women were more likely to have a record of mammography (46% v 20%; P=0.03) and of cervical smears than women in minority ethnic groups. CONCLUSION--Despite major socioeconomic inequity, equitable recording of preventive activity for the major causes of death for white, black and Bangladeshi populations is possible. Chinese and Vietnamese people had lower levels of recording and consultation. Mammography and, to a lesser extent, cervical cytology are inequitably recorded and require additional support at practice level.  相似文献

The quality of contents of general practice records was assessed by retrieving clinical information pertaining to hypertension in 171 consecutive records, and the quality of communication storage was assessed by seeking evidence of tuberculin skin tests or BCG vaccination, or both, in 298 consecutive records. There was no mention of urine analysis and blood test results in 43.3% and no record of fundal examination in 61.4% of the records of patients with hypertension. Electrocardiography was performed in 67.8% and chest x ray examination was done in 65.5% of these patients. These observations have importance for patient care, education, and research. The information regarding tuberculin skin test or BCG immunization, or both, was not available in 78% of the records. Reassessment of the individuals, however, showed that 89% of the studied population had had the test or vaccination, or both. There was thus a deficiency in communication and storage.  相似文献

Comparative evaluation of avidity of IgG to rubella virus in vaccinated persons, in patients with rubella or other exanthematous illness, and in healthy persons revealed similar patterns in post-vaccination and post-infection immunity. Virus specific low avidity IgG (index of avidity < or =30%) were detected in patients with rubella during 7 weeks after symptoms appeared as well as in vaccinated persons which were tested 6 weeks after vaccination. Low avidity antibodies in sera were detected in 96% of patients with rubella and in 75% of vaccinated persons which were not immune before immunization. Live attenuated vaccines Ervevax, Priorix, and MMR-II had similar ability to induce low avidity IgG to rubella virus. Increase of low avidity antibodies concentration was noted after immunization of children with low levels of antibodies before vaccination. After immunization of persons with high avidity antibodies in serum, index of avidity remained above threshold. Anamnestic high avidity IgG (index of avidity 51-100%) were detected in majority of immune healthy persons (96.4%) as well as in patients with exanthematous illnesses not related to rubella infection (93.6%). ELISA test-systems for detection of low avidity IgG to rubella virus allow to obtain reliable information about seroconversion rate and characteristics of immune response in vaccines. Detection of low avidity IgG in serum obtained 5-6 weeks after immunization points to primary immune response, whereas identification of high avidity antibodies reveals already immune persons.  相似文献

OBJECTIVE--To obtain information about the computerisation of general practice in Wales, and to enable more effective planning of educational provision for doctors and other primary health care workers. DESIGN--Postal questionnaire sent to all general practices in Wales. SUBJECTS--553 general practices, of which 401 (73% replied). RESULTS--The level of computerisation varied from 11 (85%) of practices in Powys Family Health Services Authority to 22 (40%) in Mid Glamorgan. Less than half of practices had a computer in only two authorities. The commonest uses of the computer were for patient registration (208 practices), repeat prescribing (180), call and recall of patients (165), and partial clinical records (122). The main suppliers were VAMP (78 practices), AAH Meditel (46), and AMC (23). 102 of 226 practices with a computer had a terminal on each doctor''s desk. Just 33 practices had full patient notes on computer and 51 had modems for electronic communication. CONCLUSION--Mechanisms to encourage greater and more sophisticated use of computers and information technology need to be explored.  相似文献

The hypothesis that general practitioners would obtain better outcomes for patients with hypertension using a computer than doctors not using a computer was tested. Sixty family physicians were randomised to two treatment strategies. "Test" physicians completed a data collection form after each visit from a patient with hypertension and mailed the forms to the test centre for processing. Computer feedback on management was mailed to the doctors. This encouraged doctors to apply the "stepped care" protocol, supplied charts of diastolic blood pressure v time, and ranked patients'' diastolic blood pressures by percentile. Letters were mailed to patients to remind them of appointments. "Control" doctors filled out the same data collection forms as test physicians, but neither doctors nor patients received computer feedback. Physicians who used the computer saw more patients per practice than control doctors (test 50 patients, control 40). For all patients the length of follow up was significantly longer in test practices (test 199 days, control 167), and a smaller percentage dropped out of active treatment in test practices (test 37.5%, control 42.1%). For patients with "moderate" hypertension of a baseline diastolic pressure of greater than 104 mm Hg the mean score of the last recorded pressure was below the goal of 90 mm Hg in test practices (88.5 mm Hg), but it failed to reach this goal in control practices (93.3 mm Hg). A greater average reduction of diastolic pressure was achieved in test practices (test 21.7 mm Hg, control 16.7 mm Hg). Though patients with "moderate" hypertension were better controlled in test practices than in control practices, the patients in test practices visited their doctors less often (test 13.3 visits per patient-year, control 17.4 visits). Among patients with newly detected hypertension test practices achieved a greater reduction in diastolic pressure than control practices (test 15.1 mm Hg v control 11.3 mm Hg) and more sustained control of hypertension (test 323 days per patient-year with a diastolic pressure of 90 mm Hg or less v control 259 days).  相似文献
