The development and application of a scale of acculturation

As Australia is one of the most multicultural societies in the world, acculturation of migrants and changes in migrants' health status should be an important focus of public health research. The absence of an accepted measure of acculturation is one barrier to exploring the relationship between acculturation and health. This paper presents data from a study of 851 Arabic-speaking adults attending 20 Arabic-speaking general practitioners in Canterbury, Sydney. An eight-item scale assessing acculturation was developed with a structural equation modelling program (LISREL). This acculturation scale was based on similar scales used with Hispanic populations, was theoretically grounded and had high internal consistency and criterion-related validity. To show the application of a scale of acculturation, patients' preferences for participation in medical decision making, according to level of acculturation, were examined. After adjustment for age, sex and highest level of formal education, significant inverse associations between acculturation and preferences for patient (versus family) involvement in medical decision making were found. Mechanisms for how acculturation affects health need to be explored.     

Eating habits of employees in the metal industry: determinants and patterns]

OBJECTIVE: To describe the proportion of frequent attenders among primary health care patients and their sociodemographic characteristics, morbidity and reasons for encounter. DESIGN: A cross-sectional case-control study. SETTING: A municipal health centre in Oulainen, a small rural town in northern Finland. PARTICIPANTS: Three hundred and four frequent attenders (eight or more visits to health centre physicians (GPs) during the year 1994) and 304 age- and sex-matched controls. MAIN OUTCOME MEASURES: Sociodemographic characteristics, numbers of encounters, chronic diseases classified by ICD-9 and reasons for encounter coded by the International Classification of Primary Care chapter codes (ICPC). RESULTS: 4.7% of the population aged 15 years or older and 6.8% of the annual patients were frequent attenders and they made 23.5% of all encounters with GPs. The frequent attenders had lower basic education and there were more people on disability pension among them. They had significantly more mental disorders and diseases of the musculoskeletal and digestive systems than the controls. The frequent attenders' most common reasons for encounter were musculoskeletal problems, and they had significantly more musculoskeletal, digestive system and psychiatric reasons for encounters than the controls. CONCLUSIONS: Frequent attenders express more somatic and less psychiatric reasons for encounter than can be assumed according to their morbidity. The role of somatization is discussed.     

Teenagers' views on the general practice consultation and provision of contraception. The Adolescent Working Group

BACKGROUND: The rate of unwanted pregnancies in adolescents in the United Kingdom (UK) is one of the highest in Europe and is a major reason for the RCGP's concern at the under-use of general practitioners' (GPs') contraceptive services by young people. AIM: To discover the attitudes of 15- to 16-year-olds to the GP consultation and contraceptive services. METHOD: Questionnaires were completed as part of an evaluation of a novel sex education programme in 30 schools in 1994, and provided the data for this study. A total of 4481 teenagers (51.6% male and 48.4% female completed the questionnaires in their classrooms under conditions of complete confidentiality. RESULTS: The median consulting rate per year was two for males and three for females. Over 60% of adolescents attended the consultation with a parent. Of the males, 27.5% 'felt that the discussion with their GP could be relayed to their parents against their wishes', as did 25.1% of the females. Other difficulties with GP appointments were identified as embarrassment (63% of females and 46% of males), difficulty getting a quick appointment (44% of both males and females), and an unsympathetic GP (32% of females and 20.5% of males). CONCLUSIONS: Adolescents identify significant factors blocking them from easy access to consultation with their GP. These included lack of trust in confidentiality, lack of staff friendliness, and delay in appointment. Consideration of how these blocks can be removed will assist in providing improved contraceptive services in primary care. General practices need to consider the above factors when providing contraceptive and other services to their teenage patients.     

Improving smoking cessation advice in Australian general practice: what do GPs suggest is needed?

Smoking cessation advice from a general practitioner (GP) significantly increases quit rates among patients who smoke. However, smoking is not discussed during most routine consultations with smokers. This study describes GPs' own views about strategies to support their cessation advice. In 1997, a random sample of 311 GPs in NSW (73% response rate) completed a self-administered questionnaire about smoking cessation. Most respondents were 'very confident' about discussing the health effects of smoking (81.7%). Fewer were as confident about negotiating a quit date (21.5%) or using evidence-based smoking cessation techniques (19.3%). The top three preferred strategies to support smoking cessation advice were all resources for patients: subsidised nicotine replacement therapy (rated as 'quite useful' by 60.5%), pamphlets (55.0%) and free access to smoking cessation clinics (50.8%). Skills training (39.7%) was the preferred resource to improve practitioner effectiveness. Interventions combining skills training with patient resources are likely to be well received by GPs.     

Differences in perceived and presented adverse drug reactions in general practice

BACKGROUND: Postmarketing surveillance (PMS) studies are frequently based on data from general practitioners (GPs). Patients, however, do not always report to their GP suspected adverse drug reactions. SETTING: A postmarketing cohort study on adverse reactions to sumatriptan, performed with assistance of drug dispensing GPs in The Netherlands. METHODS: Questionnaires were sent to all drug-dispensing GPs in The Netherlands, as well as to their patients on sumatriptan. To avoid bias, no specific adverse reactions were mentioned in the questionnaires. RESULTS: Of the GPs, 589 (86%) responded; of the patients, 1202 (70%) responded. The most frequently reported suspected adverse reactions to sumatriptan reported by the GPs were dizziness (1.7%), nausea or vomiting (1.5%), drowsiness or sedation (1.4%), and chest pain (1.3%). The most frequently reported suspected adverse reactions by the patients were paraesthesia (11.7%), dizziness (8.1%), feeling of heaviness (8.0%), and chest pain (7.9%). Neither the GPs nor the patients reported serious adverse reactions. CONCLUSIONS: First, patients experience significantly more suspected adverse reactions than are registered by their GP. In view of this higher frequency of reporting of suspected adverse reactions, postmarketing studies with data from GPs only, may underestimate the cumulative incidence of adverse reactions. Second, we conclude that it is possible to obtain useful additional information about adverse drug reactions from patients by sending them questionnaires via their GP.     

General practitioner involvement in hospital in the home. The hospital's view

INTRODUCTION: Programs involving hospitals and general practitioners (GPs) have become more commonplace, with a greater emphasis on integration of health services emerging over the last generation. Hospital in the home (HIH) refers to the delivery of acute hospital services such as intravenous therapy, anticoagulation and wound care to patients in their own homes. This study sought to determine the extent to which HIH units had involved urban GPs, issues related to GP involvement, and the likely future of such involvement. METHOD: Telephone administered structured survey to all urban HIH coordinators/directors in Melbourne, Australia. RESULTS: All 14 identified HIH coordinators were interviewed. Five units reported a direct role for GPs, six reported no role and three reported a limited role in managing intercurrent illnesses. Coordinators felt that variability of GP response and skills, GP availability and patient control were significant issues. An increase in future GP involvement was uncertain and conditional. DISCUSSION: One-third of urban hospitals surveyed have involved GPs in their programs. However, issues such as variability in skills, enthusiasm and availability threaten expansion of such involvement. This calls for a review in the way GPs are involved in hospital programs, and for better relationships with hospital nursing staff. Limiting the number of involved GPs in any hospital-GP program may offer advantages to both groups. Despite the movement of hospital work into the community, GP involvement in such work is not guaranteed.     

Antenatal HIV antibody testing in Australia

OBJECTIVE: To evaluate the role of voluntary antenatal testing in HIV surveillance and prevention by examining antenatal HIV antibody testing practice and policy in Australia. DESIGN: Cross-sectional study using a self-administered questionnaire. SUBJECTS AND SETTING: Specialist obstetricians and gynaecologists and general practitioners (GPs) affiliated with the Royal Australian College of Obstetricians and Gynaecologists and Australian public hospital antenatal clinics, August-November 1992. MAIN OUTCOME MEASURES: The percentage of public hospital antenatal clinics and specialist and GP obstetricians in Australia who tested pregnant women for HIV antibody as part of their antenatal care, and the proportion of pregnant women in Australia who had an antenatal HIV antibody test in the 1991-92 financial year. RESULTS: Questionnaires concerning antenatal HIV antibody testing were completed by 90% (993/1108) of specialists, 87% (2134/2461) of GPs and 93% (215/230) of public hospitals surveyed. Of the 706 specialists and 1503 GPs who reported that they were currently engaged in obstetric care, approximately 60% (430/706) and 935/1503, respectively) offered antenatal HIV testing either to all pregnant women or to selected groups at risk. There were significant differences in testing patterns between States and Territories. For the 95 public hospitals with antenatal clinics, 81% (77) offered the HIV antibody test to all or selected groups of pregnant women; these percentages did not differ significantly between States and Territories. It was estimated that 25% of pregnant women seen by specialists, 29% seen by GPs and 9% seen in public hospital clinics were tested for HIV antibody as part of their antenatal care in 1991-92. CONCLUSIONS: In Australia approximately one in five pregnant women were tested for HIV antibody as part of their antenatal care in 1991-92. Voluntary HIV testing in pregnancy may provide unrepresentative data for measuring the prevalence of HIV infection in pregnant women.     

Susceptibility to vaccine-preventable diseases in a sexually transmitted disease clinic population

OBJECTIVE: To determine whether general practitioners (GPs) had received Australian guidelines on early detection, screening and surveillance for colorectal cancer or rectal bleeding, and whether their reported practice conformed with these guidelines. DESIGN: Cross-sectional postal survey of self-reported practice. PARTICIPANTS AND SETTING: 213 GPs in practice in the southern metropolitan area of Perth, Western Australia, were randomly selected from the Fremantle Regional Division of General Practice database and surveyed in March 1997. RESULTS: Replies were received from 155 (73%) of the GPs, and 110 reported receiving guidelines (from the Australian Gastroenterology Institute [AGI], 44; Gut Foundation of Australia [GFA], 40; others, 6; and not specified, 20). GPs who reported receiving guidelines were significantly more likely to screen for colorectal cancer (99/110; 90%) than those who reported not receiving guidelines (33/45; 73%) (P = 0.008). The commonest method to investigate people with identifiable risk factors for colorectal cancer was colonoscopy. Reported screening frequencies in asymptomatic patients with above-average risk (family history of colorectal cancer or past history of adenomatous polyps or colorectal cancer) were significantly higher than recommended by AGI and GFA guidelines (P < 0.05). Up to 24% of GPs investigated altered bowel habit or bleeding per rectum with faecal occult blood testing. CONCLUSIONS: Most GPs report having received guidelines. Reported screening frequency was higher than recommended for most above-average-risk patients, which will result in excessive consumption of resources without benefits for cancer prevention.     

Suicide in urban New South Wales, Australia 1985-1994: socio-economic and migrant interactions

Variation of suicide with socio-economic status (SES) in urban NSW (Australia) during 1985-1994, by sex and country or region of birth, was examined using Poisson regression analysis of vital statistics and population data (age >? approximately 15 yr). Quintiles of SES were defined by municipality of residence and comparisons of suicide by SES were adjusted for age and country (or region) of birth (COB), and examined by COB. Risk of suicide in females was 28% that of males for all adults and 21% for youth (age 15-24 yr). Suicide risk was lower in males from southern Europe, Middle East and Asia, and higher in northern and eastern European males, compared to the Australian-born. Risks for suicide increased significantly with decreasing SES in males, but not in females. The relationship of male suicide and SES was stronger when controlled for COB. For males, the relative risk of suicide, adjusted for age and COB, was 66% higher in the lowest SES quintile compared to the highest quintile. and 39% higher for youth (age 15-24 yr). For male suicide, the population attributable fraction for SES (less than the highest quintile) was 27%. Analysis of SES differentials in male suicide according to COB indicated a significant inverse suicide gradient in relation to SES for the Australian-born and those born in New Zealand and the United Kingdom or Eire, but not in non-English speaking COB groups, except for Asia. For Australian-born males, suicide risk was 71% higher in the lowest SES group (compared to the highest), adjusted for age. These findings indicate that SES plays an important role in male suicide rates among the Australian-born and migrants from English-speaking countries and Asia, and among youth; but not in female suicide, nor suicide in most non-English speaking migrant groups. Reduction in SES differentials through economic and social policies may reduce male suicide in lower SES groups and should be seen to be at least as important as individual level interventions.     

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.     

Stroke services in general practice--are they satisfactory?

BACKGROUND: The contribution of general practice and primary care teams to stroke care has received surprisingly little attention despite research evidence on the importance of coordinated care. AIM: To determine general practitioners' (GPs') and their patients' satisfaction with hospital and community services for stroke patients in Grampian Region, Scotland. METHOD: A questionnaire survey of 138 stroke patients and their GPs was carried out six weeks after each patient was discharged home between June 1995 and January 1996. Outcomes measured were GP and patient satisfaction with services, Barthel Index, Hospital Anxiety and Depression scores, London Handicap Score, and Homsat and Hospsat scores (satisfaction with stroke services). RESULTS: Response rates of 95% (131) for GPs and 91% (125) for patients were obtained. GPs and patients were generally satisfied with services. Stroke patients were more likely to have had contact with their GP than with any other service. Adverse comments from GPs focused on problems with hospital discharge letters. At six weeks, patients received an average of 2.5 community services and 1.5 hospital services, but there was wide variation across disability groups. CONCLUSIONS: Levels of satisfaction were high, but the wide range and variation in services used by patients emphasized the complexity of the primary care of stroke patients; the need for coordination, review and effective links with hospital; and the key role of the GP.     

Complex formation of the nonstructural protein 3 of hepatitis C virus with the p53 tumor suppressor

BACKGROUND: Length of survival of females with cystic fibrosis is worse than it is in males. Results of current research have shown an important correlation among dietary intake, nutritional status, lung function, and survival. The purpose of this study was to explore gender differences in dietary intake and pancreatic enzyme replacement therapy in males and females with cystic fibrosis. METHODS: The study was a cross-sectional measurement of clinical characteristics, energy, and fat intakes in males and females attending the cystic fibrosis outpatients clinics of the John Hunter Hospital, Newcastle, Australia. Twenty-nine subjects, (17 females and 12 males), completed 4-day weighed food records to measure total energy intake and the contribution of macronutrients and to document use of pancreatic enzyme replacement therapy. Energy intake was assessed as the percentage of the recommended energy intake for age and sex. RESULTS: Females with cystic fibrosis had significantly lower energy and fat intakes than males, whereas the females used significantly more pancreatic enzyme replacement therapy. There were no significant differences in clinical characteristics between groups. CONCLUSION: The results support the possibility that gender differences in the energy and fat intakes of older patients may contribute to differential median survival time of males and females with cystic fibrosis.     

Chlamydia pneumoniae in coronary and iliac arteries of Japanese patients with atherosclerotic cardiovascular diseases

OBJECTIVE: This pilot study was undertaken to assess the need and acceptability of a theoretically based audit model to assist GPs improve their asthma care. METHOD: Seventeen GPs from two GP divisions conducted a chart audit and patient survey of asthma patients presenting during the 8 week audit period. Audit results were discussed at a workshop providing a forum for GP peer groups to review their asthma care against current guidelines. This workshop allowed the GPs to develop strategies to improve their asthma care in the context of the resources of their individual practice, GP division, local community and health services. RESULTS: Of the 243 asthma patients audited 177 (72.8%) had a review of their asthma recorded in the past 12 months, 138 (56.8%) were prescribed regular preventive therapy and 118 (48.2%) had been given an asthma action plan. Despite the time commitment required to participate in the activity, 16 respondents who answered the audit evaluation questionnaire reported that the audit was a useful process and 15 (93.8%) stated that it had motivated them to change their practice. CONCLUSION: The results confirmed the need for improved asthma care in general practice and demonstrated the feasibility of the GP-peer led, regionally coordinated, audit-workshop model.     

Antibodies of the anti-Yo and anti-Ri type in the absence of paraneoplastic neurological syndromes: a long-term survey of ovarian cancer patients

PURPOSE: To determine the association between lipids, microalbuminuria and systemic blood pressure. Urinary albumin excretion rate (AER) was determined in timed overnight urine samples by radioimmunoassay. Microalbuminuria was defined when two out of three urine samples had AER ranging 20-200 micrograms/min. Lipids were determined by colorimetric methods (total cholesterol, HDL cholesterol and triglycerides). METHODS: Fifty patients with insulin dependent diabetes mellitus (28 females, 22 males) aged 21.9 +/- 7 years and with diabetes duration of 6.8 +/- 5.8 years attending the outpatients diabetes clinic were studied cross-sectionally. RESULTS: Microalbuminuria was present in 12% of our patients. A high systolic blood pressure (SBP) was found in microalbuminuric patients (p = 0.003). No difference concerning serum lipids were found in comparison between normo and microalbuminuric patients, although 20% of all patients had increased cholesterol and LDL cholesterol and 4% had high HDL cholesterol and triglycerides levels. Stepwise multiple regression analysis showed that SBP was the only significant independent variable to influence AER (r = 0.42 r2 = 0.18 p = 0.002). CONCLUSION: Although in our study, microalbuminuria was associated only with SBP, the independent alteration of lipids in young IDDM patients must be considered as a possible additional risk factor for cardiovascular disease.     

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.     

Predictions of hospital mortality rates: a comparison of data sources

BACKGROUND: Complementary medicine is increasingly popular with patients and with GPs, although it still remains mainly in the private sector. Few data are available from the private sector about patient-consulting patterns and outcome. OBJECTIVES: We aimed to describe detailed consulting patterns, help-seeking behaviour and outcome of care for patients attending a group of private complementary practitioners in a single general practice surgery. METHOD: Prospective data on consulting patterns were collected from all 147 new patients attending complementary practitioners over a 12-month period. For the first 30 weeks of this period, additional information on help-seeking behaviour and outcome, as measured by the SF-36 health survey and Measure Yourself Medical Outcome Profile (MYMOP), was collected by questionnaires from 46 out of the 68 new patients. The same information was collected from a systematic one-in-seven sample of GP patients. RESULTS: Patients seen by complementary practitioners did not vary significantly in sex and age from GP patients, except in the low numbers of children. Almost half the patients had been symptomatic for over a year and musculoskeletal disorders accounted for 66% of problems; but there was much variation between the therapies. The average number of visits per patient was three for osteopathy and homeopathy but eight for acupuncture and reflexology. The change in MYMOP scores after four weeks showed a statistically significant improvement in both complementary and GP patients, which was to similar degrees except that the mean change in well-being was significantly greater for complementary patients. CONCLUSION: Prospective data collection in single settings adds valuable information to a little-researched area. This study illustrates how individual each complementary therapy is in its patient characteristics, problem category and length of treatment. The particular improvement in well-being with complementary therapy requires confirmation in other studies.     

Family physician consultation by patients with rheumatoid arthritis or gonarthrosis/coxarthrosis

OBJECTIVE: To determine how often patients with rheumatic joint disease consult their general practitioner (GP), and if there are disease and patient characteristics that influence GP consultation of gonarthrosis/coxarthrosis patients. DESIGN: Prospective record investigation. SETTING: Seven GP centres in the southeast of the Netherlands. METHOD: All patient contacts were registered prospectively in the seven GP centres: 46 concerned patients with rheumatoid arthritis (RA), 122 patients with gonarthrosis/ coxarthrosis. Patient and disease characteristics were collected on intake sheets. RESULTS: Three-quarters of the RA patients were periodically seen (mostly by a specialist), and 47% of the gonarthrosis/coxarthrosis patients (as often by their GP as by a specialist). Of the RA patients and of the gonarthrosis/coxarthrosis patients 74% and 89% respectively consulted their GPs in one year (the average numbers of contacts were 4.7 and 5.0); 50% and 57% did so because of the chronic joint disease (with 2.2 and 1.6 contacts respectively). No disease characteristics and only a few patient characteristics (arthroplasty, chronic use of medication) of patients with gonarthrosis/coxarthrosis influenced GP consultation. CONCLUSION: Patients with rheumatic joint disease often consult their GP, but not always because of this illness. If they consult their GP, they usually do so more than once a year.
