Can morbidity associated with untreated asthma in primary school children be reduced?: a controlled intervention study.

OBJECTIVE--To determine whether an intervention programme based on existing school and community resources can reduce school absence and improve participation in games lessons and sport in children with unrecognised or undertreated asthma. DESIGN--Parallel group controlled intervention study. SETTING--102 primary schools in Nottingham: 49 were randomised to receive the intervention and 53 to be control schools. SUBJECTS--All children aged 5 to 10 years with parent reported absence from school because of wheezing in the previous year and taking no treatment or beta agonists only. INTERVENTIONS--Children with asthma were referred to their general practitioner for assessment of symptoms and treatment. Teachers were given education on asthma by the school nurse in 44 of the 49 intervention schools. MAIN OUTCOME MEASURES--Changes in school absence and missed games and swimming lessons because of wheezing, and schools'' policy towards management of asthma in school. RESULTS--Of 17,432 children screened, 451 met the entry criteria--228 in intervention schools and 223 in control schools. 152 (67%) children in intervention schools visited their general practitioner, of whom 39 (26%) were given a new diagnosis of asthma and 58 (38%) had treatment for asthma increased or changed. Over the next academic year mean (SE) parent reported school absence due to wheezing fell significantly, but to a similar extent, in both intervention and control schools (0.82 (0.11) and 1.09 (0.21) weeks respectively). There was little change in school recorded absence or participation in games lessons and swimming lessons in either group. At the end of the study intervention schools were more likely to have improved aspects of management of asthma in school. CONCLUSION--The intervention resulted in a majority of children being assessed by their general practitioner and improved teachers'' understanding and management of asthma, but it did not result in any appreciable reduction in morbidity.     

Avoidable referrals? Analysis of 170 consecutive referrals to secondary care.

OBJECTIVE--To determine appropriateness of referrals from primary care to secondary care. DESIGN--Retrospective evaluation of appropriateness of referrals from a single-handed general practice: evaluations carried out independently by referring doctor and by second general practitioner who worked in same area and had access to similar secondary care services. SUBJECTS--168 referrals made between 1 October 1990 and 31 March 1991 and followed up for up to 12 months by matching with available information on outcome of episode of care. MAIN OUTCOME MEASURES--Appropriateness of referral and reasons for inappropriate referrals. RESULTS--110 referrals were agreed to be appropriate and 58 were considered avoidable. The reason for 32 of the inappropriate referrals was lack of resources: 10 were due to lack of information (mainly failure of hospitals to pass on information to general practitioner), nine were due to a deficient primary health care team; five were due to insufficient use of home care nurses, three were due to absence of direct access to day hospital, and five were due to lack of access to general practitioner beds or other facilities. Most of the remaining 26 avoidable referrals were because available resources had not been fully used, because recognised management plans had not been followed, or because of lack of skills to perform certain procedures. CONCLUSIONS--Many theoretically avoidable referrals were due to managers'' and politicians'' decisions about allocation of resources, but some inappropriate referrals could be avoided by assessment of general practitioners'' needs for further knowledge and skills.     

Self referral to an accident and emergency department for another opinion.

OBJECTIVE--To determine whether patients referring themselves to an accident and emergency department for another opinion after consulting their general practitioner present with serious illness, show any risk factors for being admitted, or are more likely to be patients of particular practitioners. DESIGN--Six month prospective survey. SETTING--District general hospital''s accident and emergency department, receiving 42,000 new patients a year. PATIENTS--180 Patients identified as attending for another opinion having already consulted a general practitioner. INTERVENTIONS--Classified as admission, referral to specialist clinic, follow up in accident and emergency department, or referral back to general practitioner. END POINT--Admission, with an analysis of admitted patients. MEASUREMENTS AND MAIN RESULTS--General outcome, diagnostic category, age, time of attendance, time since seen by general practitioner, and name of general practitioner were recorded. Forty seven patients were admitted, 99 were discharged back to the general practitioner (62 without a letter), and two died. Patients were most likely to be admitted if they attended within 24 hours after seeing a general practitioner, were aged under 5, or presented with respiratory or gastrointestinal complaints. Some general practitioners were overrepresented. CONCLUSIONS--Important disorders present in this way, and therefore these patients should be seen by a doctor. Information about these attendances could be useful to general practitioners in reviewing their performance.     

Prospective regional study of planned home births. Home Birth Study Steering Group.

OBJECTIVE: To collect data from a cohort of women requesting a home birth and examine the experience and outcome of pregnancy, the indications for hospital transfer, and the attitudes of mothers, midwives, and general practitioners. DESIGN: Follow up study with anonymised postal questionnaires. SETTING: Northern Regional Health Authority area. SUBJECTS: The 256 women resident in the Northern region who expected to deliver in 1993 and whose request for a home birth became known to one of the local supervisors of midwives. Limited cross validating information was also collected retrospectively on all other women delivering a baby outside hospital in 1993. MAIN OUTCOME MEASURES: Rate of and reason for transferred care; maternal, midwifery, and general practitioner views; perinatal outcome. RESULTS: Five women miscarried, leaving 251 in the study. Of these, 142 (57%) delivered at home. There were 17 (7%) caesarean sections but no perinatal deaths. General practitioners had reservations about half of the booking requests. Two thirds of the women thought they had not been offered any option about place of birth, 74 (29%) were referred to hospital for delivery before the onset of labour, and 35 (14%) were referred to hospital during labour. Intrapartum transfers were uneventful, and half the mothers commented spontaneously that they valued having spent even part of their labour at home. CONCLUSIONS: Home birth is valued for its family setting. General practitioners'' support is sought and influential but uncommon, possibly because of a lack of understanding of the responsibilities of the midwife and general practitioner.     

Randomised controlled trial of general practitioner intervention in patients with excessive alcohol consumption.

OBJECTIVE: To determine effectiveness of advice from general practitioners to heavy drinkers to reduce their excessive alcohol consumption (35 U or more a week for men, 21 U or more for women). DESIGN: Randomised, controlled double blind trial over 12 months with interim assessment at six months. SETTING: Group practices (n = 47; list size averaging 10,000) recruited from Medical Research Council''s general practice research framework, mostly in rural or small urban settings. PATIENTS: Patients recruited after questionnaire survey. Of total of 2571 (61.2%) of 4203 patients invited for interview who attended, 909 (35.4%) stated that in past seven days they had drunk above the limits set for study and had not received advice; they were randomised to control and treatment groups. INTERVENTIONS: Patients in treatment group were interviewed by general practitioner (who had had a training session) and received advice and information about how to reduce consumption and also given a drinking diary. END POINT: Study aimed at detecting a reduction in proportion of men with excessive alcohol consumption of 30% in treatment group and 20% in control group (for women 40% and 20%, respectively) with a power of 90% at 5% level of significance. In addition, corroborative measures such as estimation of gamma-glutamyltransferase activity were included. MEASUREMENTS AND MAIN RESULTS: At one year a mean reduction in consumption of alcohol of 18.2 (SE 1.5) U/week had occurred in treated men compared with a reduction of 8.1 (1.6) U/week in controls (p less than 0.001). The proportion of men with excessive consumption at interview had dropped by 43.7% in the treatment group compared with 25.5% in controls (p less than 0.001). A mean reduction in weekly consumption of 11.5 (1.6) U occurred in treated women compared with 6.3 (2.0) U in controls (p less than 0.05), with proportionate reductions of excessive drinkers in treatment and control groups of 47.7% and 29.2% respectively. Reduction in consumption increased significantly with number of general practitioner interventions. At one year the mean value for gamma-glutamyltransferase activity had dropped significantly more in treated men (-2.4 (0.9)IU/l) than in controls (+1.1(1.0)IU/l; t = 2.7, p less than 0.01). Reduction in gamma-glutamyltransferase activity tended to increase with number of intervention sessions in men. Changes in gamma-glutamyltransferase activity in women and changes in other indicators in both sexes did not differ significantly between treatment and control groups. CONCLUSIONS: If the results of this study were applied to the United Kingdom intervention by general practitioners could each year reduce to moderate levels the alcohol consumption of some 250000 men and 67500 women who currently drink to excess. General practitioners and other members of the primary health care team should therefore be encouraged to include counselling about alcohol consumption in their preventive activities.     

Prevalence of Chronic Conditions in Australia

Objectives

To estimate prevalence of chronic conditions among patients seeing a general practitioner (GP), patients attending general practice at least once in a year, and the Australian population.

Design, setting and participants

A sub-study of the BEACH (Bettering the Evaluation and Care of Health) program, a continuous national study of general practice activity conducted between July 2008 and May 2009. Each of 290 GPs provided data for about 30 consecutive patients (total 8,707) indicating diagnosed chronic conditions, using their knowledge of the patient, patient self-report, and patient''s health record.

Main outcome measures

Estimates of prevalence of chronic conditions among patients surveyed, adjusted prevalence in patients who attended general practice at least once that year, and national population prevalence.

Results

Two-thirds (66.3%) of patients surveyed had at least one chronic condition: most prevalent being hypertension (26.6%), hyperlipidaemia (18.5%), osteoarthritis (17.8%), depression (13.7%), gastro-oesophageal reflux disease (11.6%), asthma (9.5%) and Type 2 diabetes (8.3%). For patients who attended general practice at least once, we estimated 58.8% had at least one chronic condition. After further adjustment we estimated 50.8% of the Australian population had at least one chronic condition: hypertension (17.4%), hyperlipidaemia (12.7%), osteoarthritis (11.1%), depression (10.5%) and asthma (8.0%) being most prevalent.

Conclusions

This study used GPs to gather information from their knowledge, the patient, and health records, to provide prevalence estimates that overcome weaknesses of studies using patient self-report or health record audit alone. Our results facilitate examination of primary care resource use in management of chronic conditions and measurement of prevalence of multimorbidity in Australia.     

Roles,risks, and responsibilities in maternity care: trainees' beliefs and the effects of practice obstetric training.

OBJECTIVES--To document the content of practice obstetric vocational training, the beliefs of general practitioner trainees about the roles of midwives and general practitioners in maternity care, and the risks of providing such care; and to ascertain if undergoing such training affects their beliefs. DESIGN--Confidential postal questionnaire survey. SUBJECTS--Random one in four sample of all general practitioner trainees in the United Kingdom on vocational training schemes or in training practices in autumn 1990. MAIN OUTCOME MEASURES--Beliefs scored on seven point Likert scales and characteristics of trainer and training practice. RESULTS--Of 1019 trainees sent questionnaires, 765 (75.1% response rate) replied; 638 (83.3%) had done some part of their practice year. Of their trainers, 224 (35.1%) provided full obstetric care. 749 (99%) and 364 (48%) trainees believed that midwives and general practitioners respectively have an important role in normal labour; 681 (91.7%) trainees believed that general practice intrapartum care is a high risk "specialty." Those trainees whose trainers provide full obstetric care were significantly more likely to believe that both midwives and general practitioners have an important role in abnormal labour and to see the provision of intrapartum care as an incentive to join a practice. CONCLUSION--In this series most general practitioner trainees believed that both midwives and general practitioners have important roles in maternity care. Exposure of trainees to the provision of full obstetric care while in their training practice resulted in a more positive attitude towards the provision of such care by general practitioners.     

Domiciliary consultations: some facts and questions.

The domiciliary consultation scheme introduced at the start of the NHS enables joint consultation between a consultant and general practitioner in a patient''s home when the patient cannot attend hospital on medical grounds. Consultants claim a fee from the NHS, general practitioners do not. Data from the Department of Health and Social Security on domiciliary consultations in England and Wales during 1981-6 were analysed. The number of domiciliary consultations fell during 1981-6 from 429,759 in 1981 to 387,394 in 1986, a fall of 10%, whereas the numbers of consultants and general practitioners increased by 1404 (12%) and 2400 (10%), respectively. The yearly rate of domiciliary consultation per consultant fell by 19% from 36 in 1981 to 29 in 1986 and that per general practitioner by 18% from 18 to 15. In 1986 geriatric medicine had the highest rate of domiciliary consultation per consultant (187) followed by psychiatry (89), general medicine (52), dermatology (49), rheumatology (42), general surgery (36), gastroenterology (35), thoracic medicine (34), and orthopaedics (30). In 1986 all specialties apart from clinical pharmacology and therapeutics and clinical genetics showed a decrease in the yearly rate of domiciliary consultation when compared with the rate for 1981. Domiciliary consultation seems to have become a domiciliary visit by the consultant alone. At an estimated cost of about 20m pounds for 1988 the scheme needs critical evaluation.     

Comparison of response rates to a postal questionnaire from a general practice and a research unit.

A postal questionnaire study was carried out in an urban general practice to determine the effect of the introductory letter being sent by the participants'' own general practitioner compared with that from a letter sent directly from a research unit. By sequential sampling 409 individuals aged between 40 and 59 were assigned to one of two groups. The people in one group were written to by their own general practitioner and those in the other by a doctor from a research unit. Husbands and wives were paired and were always sent the same letter. A second letter was sent to nonresponders after one month. The response rate to the general practitioner was significantly higher than that to the doctor in the research unit (85% compared with 75%) and differed by age and sex. The results have important implications for other research workers and suggest that general practitioners are in a key position in the conduct of medical and epidemiological research.     

Community Nurses' View of General Practice Attachment

An analysis of 98 health visitors and district nurses attached and non-attached to general practitioners in three local authority areas showed that most of them were aged over 40 and that many had entered domiciliary work because of the convenient hours or because of its intangible attractions. Adequate preparation for attachment was considered important, particularly a clear definition of the roles of the attached staff and their relationships to other workers in the practice.Attached staff were found to be much more satisfied with the information given by the general practitioner about their patients than were unattached staff, and the former usually had access to the patients'' medical records. The principal advantages of attachment were listed as access to family history; improved co-ordination within the practice and co-operation with the social services; favourable patient response; and increased mileage and work-load; the impossibility of crossing local authority boundaries; and having to deal with families registered with more than one doctor.     

Newly registered elderly patients: who are they and why such delay in the transfer of their medical records?

The time taken to transfer the records of elderly patients registering with a new general practice was investigated. Thirty five (5%) of a total of 671 patients aged 75 and over were entered as new patients on to the age-sex register of an urban group practice during one year. Twenty nine had moved into the area and six had changed their general practitioner for personal and other reasons. An average of 141 (range 71-296) days elapsed before dispatch of their medical records to the new practice. During this period an average of 3·5 (range 0-15) consultations with a general practitioner were recorded, indicating the need of such patients for medical care. The long delays were caused by the processing of medical records at the central register and the transfer of records between family practitioner committees and general practitioners. Delays were most apparent in the time taken for general practitioners to dispatch the necessary documents to the family practitioner committees, and these should be minimised.The use of a summary card written and updated by the general practitioner and retained by the patient would facilitate continuing care should patients change to a new practice. Meanwhile, assessment of elderly patients after registration with a new practice by a member of the primary health care team may identify problems before the records have been transferred and may help the resettlement of these high risk elderly patients.     

Should obstetricians see women with normal pregnancies? A multicentre randomised controlled trial of routine antenatal care by general practitioners and midwives compared with shared care led by obstetricians.

OBJECTIVE--To compare routine antenatal care provided by general practitioners and midwives with obstetrician led shared care. DESIGN--Multicentre randomised controlled trial. SETTING--51 general practices linked to nine Scottish maternity hospitals. SUBJECTS--1765 women at low risk of antenatal complications. INTERVENTION--Routine antenatal care by general practitioners and midwives according to a care plan and protocols for managing complications. MAIN OUTCOME MEASURES--Comparisons of health service use, indicators of quality of care, and women''s satisfaction. RESULTS--Continuity of care was improved for the general practitioner and midwife group as the number of carers was less (median 5 carers v 7 for shared care group, P<0.0001) and the number of routine visits reduced (10.9 v 11.7, P<0.0001). Fewer women in the general practitioner and midwife group had antenatal admissions (27% (222/834) v 32% (266/840), P<0.05), non-attendances (7% (57) v 11% (89), P<0.01) and daycare (12% (102) v 7% (139), P<0.05) but more were referred (49% (406) v 36% (305), P<0.0001). Rates of antenatal diagnoses did not differ except that fewer women in the general practitioner and midwife group had hypertensive disorders (pregnancy induced hypertension, 5% (37) v 8% (70), P<0.01) and fewer had labour induced (18% (149) v 24% (201), P<0.01). Few failures to comply with the care protocol occurred, but more Rhesus negative women in the general practitioner and midwife group did not have an appropriate antibody check (2.5% (20) v 0.4% (3), P<0.0001). Both groups expressed high satisfaction with care (68% (453/663) v 65% (430/656), P=0.5) and acceptability of allocated style of care (93% (618) v 94% (624), P=0.6). Access to hospital support before labour was similar (45% (302) v 48% (312) visited labour rooms before giving birth, P=0.6). CONCLUSION--Routine specialist visits for women initially at low risk of pregnancy complications offer little or no clinical or consumer benefit.     

A general production model with dependence between data from multiple surveys

A fishery‐independent survey for stock assessments is made sometimes more than once per year to detect a difference in relative sizes of fish populations (e.g., catch‐per‐unit‐effort [CPUE]) in response to a seasonal change in fish spatial distributions. Many managers tended to treat such data independently instead of systematically synthesizing them. A primary objective of this study was to synthesize all survey data via a simple hierarchical structure. I used the general (Pella‐Tomlinson) surplus production model for the illustration, because the purpose of this study was not a stock assessment, and the model was simpler than an age‐structured model. The surplus production model has about an eight decade history (since Graham's paper in 1935) and has been prominent in fish population dynamics. The logistic (Graham‐Schaefer) version was useful in the sense of simplifying the dynamics of a fish population in relation to its intrinsic growth, natural mortality, recruitment, density‐dependence, and fishery catch, but it was criticized because of its unrealistic limitations. Subsequently, the general version was suggested to accommodate flexibility and be realistic. In this study, I inferred parameters in the general surplus production model, simultaneously synthesizing all available data even from different temporal ranges. I used Georges Bank yellowtail flounder (Limanda ferruginea) data for demonstration.     

Responses by general practitioners in Avon to proposals for general practice in the white paper Working for Patients.

OBJECTIVE--To determine the views of Avon''s general practitioners about the general practice proposals within the government''s white paper Working for Patients. DESIGN--Postal questionnaire survey. SETTING--A county in south west England. SUBJECTS--All general practitioner principals (n = 537) under contract with Avon Family Practitioner Committee. MEASUREMENTS AND MAIN RESULTS--492 doctors (92%) responded to the survey. More than three quarters of the respondents were opposed to the government''s proposals on budgets for specific surgical procedures, prescribing, and diagnostic tests; and between 63% and 93% felt negative about advantages that might accrue from the proposals. Over three quarters of general practitioners were in favour of family practitioner committees monitoring work load, prescribing, and referrals. General practitioners in large, potentially budget holding practices held similar views to doctors in smaller practices. CONCLUSIONS--Avon''s general practitioners substantially reject most of the government''s proposals about general practice in the white paper Working for Patients.     

Preregistration house officers in general practice.

OBJECTIVES--To obtain from house officers who had rotated through general practice in their pre-registration year their views about their experience; and, separately, to compare the overall hours and type of work performed by hospital based and general practice based house officers. DESIGN--Postal questionnaire; and self recording of working hours and duties during four consecutive weeks. SETTING--Inner London teaching hospital and nearby general practice. PARTICIPANTS--28 preregistration house officers in general practice, 1981-91; and 12 preregistration house officers, four each in medicine, surgery, and general practice. RESULTS--26 out of 28 questionnaires were returned (response rate 93%). Twelve respondents were following or thinking of following a career in general practice. Twenty five respondents were satisfied with the clinical and educational aspects of the general practice rotation and would recommend the rotation, and 25 thought four months was about the right length of time in general practice. With regard to hours and type of work performed, hospital based house officers worked on average 55.5 hours a week (excluding on call), with an average of 12.5 hours (22.5%) spent in clinical activities; general practice based house officers worked about 41 hours a week, of which 24 hours (58%) were in clinical activities. House officers in hospital received less than one hour''s specific teaching a week; those in general practice received nearly three hours'' a week. CONCLUSIONS--A preregistration rotation in general practice is a popular alternative to the hospital based rotation. Although this is a limited study, other medical schools should consider introducing general practice options for preregistration house officers.     

Provision of first contact care out of hours in four urban areas in England.

In a typical two week period in 1984 in three urban areas with general practitioner deputising services roughly 40% of first contact patient encounters out of hours were with hospital accident and emergency departments, and only a quarter were with general practitioner deputising services, although 47%, 64%, and 97% of general practitioners in the areas had permission to use such services. Roughly a third only of the encounters were with the practices themselves, and even fewer occurred overnight (11 pm-7 am). In a fourth urban area where 68% of general practitioners formed an out of hours cooperative rota a third of the encounters were with the accident and emergency department and half (more overnight) were with the rota. The presence of a woman principal in a practice and large partnerships of four principals or more were associated with an increased proportion of encounters with the practice itself. Undue prominence may have been given to the role of deputising services in out of hours care. Paradoxically, the use of general practitioner cooperatives may result in even less personal care being given by the patient''s own practice.     

New renal scarring in children who at age 3 and 4 years had had normal scans with dimercaptosuccinic acid: follow up study.

OBJECTIVE: To determine up to what age children remain at risk of developing a new renal scar from a urinary tract infection. DESIGN: Follow up study. Families of children who had normal ultrasound scans and scanning with dimercaptosuccinic acid (DMSA) after referral with a urinary tract infection when aged 3 (209) or 4 (220) were invited to bring the children for repeat scans 2-11 years later. A history of infections since the original scan was obtained for children not having a repeat scan. SETTING: Teaching hospital. SUBJECTS: Children from three health districts in whom a normal scan had been obtained at age 3-4 years in 1985-1992 because of a urinary tract infection. MAIN OUTCOME MEASURE: Frequency of new renal scars in each age group. RESULTS: In each group, about 97% of children either had repeat scanning (over 80%) or were confidently believed by their general practitioner or parent not to have had another urinary infection. The rate of further infections since the original scan was similar in the 3 and 4 year old groups (48/176 (27%)) and 55/179 (31%)). Few children in either group known to have had further urinary infections did not have repeat scanning (3/209 (1.4%) and 4/220 (1.8%)). In the 3 year old group, 2.4% (5/209) had one or more new kidney scars at repeat scanning (one sided 95% confidence interval up to 5.0%), whereas none of the 4 year olds did (one sided 95% confidence interval up to 1.4%). The children who developed scars were all aged under 3.4 years when scanned originally. CONCLUSIONS: Children with a urinary tract infection but unscarred kidneys after the third birthday have about a 1 in 40 risk of developing a scar subsequently, but after the fourth birthday the risk is either very low or zero. Thus the need for urinary surveillance is much reduced in a large number of children.     

AIDS and the general practitioner: views of patients with HIV infection and AIDS.

An unselected series of outpatients infected with the human immunodeficiency virus (HIV) who attended two London hospitals were interviewed to assess their relationship with their general practitioner. Although most of the 192 patients were registered with a general practitioner, the doctors of only one half knew of the diagnosis. Patients feared a negative reaction from their general practitioner or were concerned about confidentiality. Although those who had told their doctor had received favourable reactions, few general practitioners attempted to counsel or educate their patients. The patients who previously had been open about their homosexuality were not more likely to have told their general practitioner of their HIV infection. Although most did not think that general practitioners were well informed about AIDS, half of the patients wished that general practitioners could take a bigger part in their care.     

Old people not known to the general practitioner: low risk group.

The elderly patients in a large general practice aged 75 and over who lived at home (n = 877) were divided into two groups according to the general practitioner''s knowledge of their risk status and were designated "risk status known" (n = 679) and "risk status not known" (n = 198). Forty-three high risk patients in the risk status known group had a functional disability score and experience of mortality that was not dissimilar to those of elderly people in institutions. The medical and social characteristics of a random sample (n = 150) of the risk status known group, after excluding the high risk patients, were compared with the risk status not known group using a Barber Wallis questionnaire. A response rate of 90% was achieved from both groups and a cumulative risk score was calculated by totalling unfavourable replies to the questions. The risk status not known group, which comprised 14% of the patients who lived at home after correcting for the number who had died and moved, had appreciably less contact with the general practitioners, had an appreciably lower cumulative risk score, were confined at home less because of ill health, were less concerned about their health, and were less in need of nursing attention. The findings of this study suggest that the elderly patients who are not known to their general practitioners are in relatively good health when compared with the patients that the general practitioner knows well.
