Feasibility and effectiveness of providing vestibular rehabilitation for dizzy patients in the community.

Since the majority of people with dizziness in the community are never referred for specialist testing and treatment, the purpose of this study was to investigate whether it was desirable and feasible to provide vestibular rehabilitation for this patient population. Demand for therapy was assessed by a survey of 9198 working age people randomly sampled from six general practices. One in 10 respondents reported current, handicapping dizziness, but fewer than 2% of those with dizziness severe enough to merit treatment proved suitable and willing to attend hospital for testing and rehabilitation. Nevertheless, vestibular rehabilitation was clearly beneficial for the 16 patients who completed the therapy programme, as their scores on measures of symptoms, disability, handicap and postural stability improved significantly post-therapy to near-normal levels. We conclude that there is a need for provision of vestibular rehabilitation in primary care for patients with dizziness in the community.

Neuro-otological and psychiatric abnormalities in a community sample of people with dizziness: a blind, controlled investigation.

OBJECTIVES: To determine neurootological and psychiatric abnormalities associated with complaints of dizziness in an epidemiological community sample of people of working age, and the extent of comorbidity between neuro-otological and psychiatric dysfunction. METHOD: A survey of 3884 people randomly selected from six general practice lists identified 262 people with significant dizziness, from which a subsample of 15 men and 22 women were recruited for testing. Dizzy subjects were evaluated by blind neuro-otological testing, computerised dynamic posturography, a computerised psychiatric assessment, neuro-otological and general medical examination, and diagnosis. An age matched control group of 18 men and 22 women underwent the same evaluation. RESULTS: Tests of auditory, vestibular, and oculo-motor function did not discriminate between dizzy subjects and controls, but dizzy subjects had significantly worse balance on posturographic testing, more diagnoses of medical disorder, and a higher prevalence of psychiatric morbidity. CONCLUSIONS: The findings suggest that dizziness in the community is typically characterised by mild physical disorder accompanied by some psychiatric disturbance. As the combination of minor physical and psychiatric disorder is known to be unusually persistent and handicapping, treatment programmes must be provided for this prevalent syndrome, perhaps by a partnership between primary care and neuro-otological and psychiatric hospital outpatient clinics with experience and expertise in the diagnosis and management of dizziness and psychiatric disturbance.

Prevalence and presentation of dizziness in a general practice community sample of working age people.

BACKGROUND: Dizziness is known to be a common, handicapping condition in the elderly, and a strong association between dizziness and anxiety disorders has been observed in hospital samples. However, little is known about the prevalence of dizziness among people of working age in the community and its implications for psychosocial functioning and general practice consultation and treatment. AIM: To determine the prevalence of dizziness, giddiness, vertigo, and unsteadiness, and associations with disability and handicap, symptoms of panic and agoraphobia, and general practice consultation and treatment. METHOD: Postal questionnaires were completed by 2064 people aged 18-64 years randomly sampled from the patient lists of four London practices. Validated survey items were used to assess symptoms, panic and agoraphobia, levels of occupational disability and handicap, and general practice consultation and treatment. RESULTS: More than one in five responders (n = 480) had experienced dizziness during the past month; nearly half of these (n = 225) reported some degree of handicap and 30% had been dizzy for more than five years. Almost half (n = 221) of those with dizziness also reported anxiety and/or avoidance behaviour. Multiple physical and psychological symptoms were associated with higher levels of handicap. Only one in four of the 225 dizzy responders reporting some degree of handicap had received any form of treatment. CONCLUSION: Dizziness is a common, chronic, and often untreated symptom in people aged 18-65 years, associated with extensive handicap and psychological morbidity.

A controlled evaluation of small-group education of general practitioners in the management of drug users.

We evaluated the effectiveness of small-group education of general practitioners (GPs) in the management of drug users. A total of 40 doctors were trained. Some 28 doctors who were unable to attend and 30 who did not want training participated as comparison groups. Sixteen months after the education, trained doctors notified significantly more drug users to the British Home Office database and more often prescribed methadone at first consultation with a drug user.

A randomized trial of the impact of telephone and recorded delivery reminders on the response rate to research questionnaires.

BACKGROUND: A range of factors have been shown to affect the response rate to mailed questionnaires, but particular strategies to improve patients' response in trials conducted in general practice require further study. METHODS: Non-responders in a larger trial were randomized to receive a telephone or recorded delivery reminder on the third contact. The cost of administration of each method was estimated. RESULTS: Significantly more patients returned completed questionnaires when sent questionnaires by recorded delivery, although the cost per patient contacted was nearly three times more than for contact by telephone. CONCLUSION: Our study indicates that sending reminders by recorded delivery, although more expensive, is more effective than telephone reminders for recruiting patients to a study in general practice using research questionnaires.

Monitoring psychosis in general practice: a controlled trial.

BACKGROUND: This trial evaluated the feasibility, acceptability and effectiveness of a structured approach to the management of schizophrenia in general practice. METHOD: All patients with non-affective psychosis (mainly schizophrenia) in four inner-city general practices were recruited. A check-list and a set of outcome measures were used by the general practitioner and the practice nurses. Information on attendances at the general practice and psychiatric out-patient departments was also collected. RESULTS: Two practices took part in the intervention and two served as control practices. Sixty-seven patients with non-affective psychosis were identified. Thirty-three (81%) of the 41 patients in the two intervention practices attended the initial assessment by the doctor and nurse, but only 13 (32%) attended the first review assessment. The attendance for the second review, after six months, was six out of 15 (40%) in one practice, but rose to 16 out of 18 (89%) in the other practice. Significant improvements were recorded in the intervention group on the Global Assessment Scale (GAS) and the Behaviour, Speech and Other Syndromes (BSO) subscore of the Present State Examination (PSE). The absolute risk reduction and relative risk reduction as a result of the intervention, as measured by the GAS scores, was 29% (95% CI 4% to 54%) and 36% (95% CI 5% to 66%), respectively, and in the case of the BSO subscores of the PSE, this was 23% (95% CI-1.8% to 47.2%) and 28% (95% CI-2.2% to 57%), respectively. For one patient to show an improvement in GAS and BSO scores 3.5 patients (95% CI 1.85 to 25) and 4.3 patients (95% CI-55 to 2.1), respectively, would need to receive the intervention. There was a significant increase in consultation rates for patients in the intervention practices. CONCLUSIONS: Health surveillance of patients with non-affective psychosis is possible in general practice.

Community care of patients with schizophrenia: the role of the primary health care team.

Schizophrenia is a severe, chronic mental disorder that usually begins in early adulthood. Recurrent relapse leading to long-term psychological and social disability means that patients may require intensive community support. Despite a recent fall in the overall numbers of patients consulting their general practitioner with mental disorders, presentations by those suffering from severe mental disorders have risen. This review encompasses the role of general practitioner in the management of schizophrenia, considering in turn drug and psychological therapies, family interventions, innovations in care, the effects of community care developments, and the liasion between primary health care and mental health professionals. There is a need for further research in the area of family-practice-based interventions involving general practitioners and the practice team.

Characteristics of drug misusers and their perceptions of general practitioner care.

BACKGROUND: Little is known about drug misusers' views of the care they receive from general practitioners. AIM: This study set out to determine drug users' views about primary health care and their relationship with their general practitioners. METHOD: A semi-structured interview was conducted with 180 drug users who were consecutive attenders at five treatment services in north east London--a general practice with a special interest in treating drug users, a private drug clinic, a community drug team, a drug dependence unit and a street agency for drug users. RESULTS: The majority of the 145 London-based drug users attending the four treatment centres other than the general practice with a special interest were registered with a general practitioner (88%). Forty-two per cent of users sought out a general practitioner prepared to treat them, rather than register with a local or the family doctor. Most drug users reported that their general practitioners were aware of their drug problems (88%) but half of the general practitioners were not prescribing replacement drugs with almost 20% of the users not receiving prescriptions claiming that this was due to lack of knowledge or trust on the part of the doctor. Sixty per cent of the drug users attending the four centres perceived that their general practitioners held negative or neutral views about them. However, 34 of the 35 drug users interviewed in the specialist general practice believed their doctors had a positive view of drug users. CONCLUSION: Most drug users were registered with general practitioners but the relationship between doctor and patient was not always easy or productive. There is a need to clarify the role of general practitioners in this field and provide them with better educational opportunities.

Withdrawal of triazolam's product licence: effect on patients 18 months later.

The product licences for triazolam in Britain were suspended in October 1991. We aimed to determine whether the sudden withdrawal of a benzodiazepine from the market constitutes a major impetus for patients to reduce or stop their benzodiazepine consumption. Patients in 10 London general practices who were prescribed triazolam in the 12 months prior to the withdrawal of its licence were interviewed. Data from written and computerized general practice records were also studied. One hundred and forty-seven patients were identified, of whom 107 (73%) were interviewed; 38 were chronic users; 68 patients had a history of serious physical illness while 33 had a history of psychiatric problems; 45% of chronic and 66% of intermittent triazolam users had stopped receiving prescriptions for benzodiazepines from 6 months after the withdrawal of triazolam's licence up to 18 months later. Only 12 (11%) recalled suffering significant withdrawal effects. We conclude that official action to curb prescribing of a benzodiazepine acts as an important stimulus for patients to reduce or stop their use of all psychotropic medication without increasing psychological morbidity or leading to unacceptable side effects.

Care of schizophrenia in general practice: the general practitioner and the patient.

BACKGROUND: The transfer of patients with chronic schizophrenia from large mental hospitals into the community has had an impact on the role of the general practitioner in the effective delivery of primary care services to these patients. AIM: A study was undertaken to assess the care available in general practice for patients with schizophrenia, the attitudes of general practitioners and patients to the care provided and the factors influencing patients' use of services. METHOD: Eighty three patients with a diagnosis of schizophrenia and 26 doctors in 13 London practices registered on the VAMP research bank took part in a series of structured and semi-structured interviews. This was followed by a systematic examination of the patients' case notes. RESULTS: Only 14 patients (17%) had no active symptoms according to the present state examination interview and 52 (63%) were currently taking antipsychotic medication. Fifty three patients were in contact with a psychiatrist. Approximately one quarter of patients were visited by a community psychiatric nurse; in 18 of these 19 cases, the main reason for contact was reported to be for administration of medication by depot injection. In all but one case, patients seeing a community psychiatric nurse were also being seen by a psychiatrist. Sixteen doctors reported having had a consultation in the previous month with a patient's relative, friend or member of hostel staff. There were considerable differences between patients and their doctors in their attitudes to the use of services. Of the 26 general practitioners, 23 were enthusiastic about the possibility of introducing shared care records. Of the 54 patients in contact with a mental health professional, only 18 favoured the use of shared care records. Most of the doctors (19, 73%) reported they would welcome a psychiatric liaison service in their practice; 40% of 53 patients said they would not. Patients receiving antipsychotic drugs and patients registered with inner city practices attended their general practitioners more frequently than those not taking antipsychotic medication and those registered with suburban practices. Use of antipsychotic medication (adjusted odds ratio (OR) 8.2, 95% confidence interval (CI) 2.2 to 30.7, P < 0.01), male sex (OR 5.8, 95% CI 1.5 to 22.1, P < 0.01) and active symptoms on the present state examination (OR 4.1, 95% CI 1.0 to 17.5, P = 0.06) were all predictive of current contact with mental health professionals. CONCLUSION: Family doctors were closely involved with the care of patients with schizophrenia and their relatives and were eager for increased liaison with secondary care services. Although patients were more resistant than doctors to management innovations this may reflect lack of familiarity with changes in community services. Greater input is needed by mental health professionals, particularly community psychiatric nurses, and some consideration of the burden of care in inner city practices is necessary in health service planning.

Accuracy of diagnosis of psychosis on general practice computer system.

OBJECTIVES: To determine the accuracy of diagnoses of schizophrenia and non-affective psychosis entered by general practitioners on a computer system. To compare recording of clinical events on computer with written records. DESIGN: Examination of case notes of all patients with a computer diagnosis of psychosis. Search of 8000 randomly selected patient records to identify patients with psychosis not recorded on computer and comparison of 141 computer and written entries for prescribing and consultation in each practice. SETTING: 13 London practices on the VAMP research bank. MAIN OUTCOME MEASURES: Accuracy of record of psychosis compared with ICD 9, American Psychiatric Association diagnostic manual, and syndrome checklist criteria. RESULTS: Computer search revealed 102 patients with schizophrenia, 78 with other psychoses, and 71 with non-affective psychosis who had adequate case notes. The sensitivity and positive predictive value of the computer diagnosis of schizophrenia were 88% (95% confidence interval 62% to 98%) and 71% (48% to 88%). For all non-organic psychoses sensitivity was 91% (74% to 97%) and positive predictive value was 91% (74% to 98%). On average 95% of all known prescriptions and 74% of all consultations were recorded on computer compared with 42% and 75% in written records. CONCLUSIONS: Recording of psychotic illness on the VAMP computer is accurate and complete. Prescribing was more fully recorded on the computer than on the written records. Computer databases of well motivated general practitioners could be used for research.

Decision making by general practitioners in diagnosis and management of lower urinary tract symptoms in women.

OBJECTIVE: To identify factors influencing decision making by general practitioners in the diagnosis and treatment of lower urinary tract symptoms in women. SETTING: Two suburban London general practices. SUBJECTS: Women presenting to their family doctor with lower urinary tract symptoms. DESIGN: After each consultation the doctor completed a questionnaire on presenting symptoms; clinical examination; investigations undertaken; presence of psychological, social, and menstrual problems; patients' requests for antibiotics; antibiotic prescribing; knowledge of the patient; attitude towards the consultation; and any other factors assisting in diagnosis and management. Finally, doctors predicted the presence or absence of clinically important bacteriuria. Each woman completed a demographic questionnaire, the 12 item general health questionnaire, and the modified menstrual distress questionnaire, after which each provided a clean catch midstream urine sample. Case notes were examined for information on previous reports of results of urine analysis. RESULTS: When the general practitioners did not know the patients well they were 4.5 times more likely to assume that there was a clinically important infection. When they knew the patient well, they were four times more likely to make a correct prediction of the test result and 12 times less likely to prescribe antibiotics. Doctors were five times more likely to predict the test result correctly in patients from social classes 1 and 2 and were six times more likely to prescribe antibiotics for the older women in the sample. CONCLUSIONS: In women presenting with urinary tract symptoms, these family practitioners seemed to take no particular regard of physical, psychological, or menstrual factors in making their assessments. They were most accurate in their prediction of the result of urine analysis and least likely to prescribe antibiotics when they had a good general knowledge of the patient. Which came first, the diagnosis or prescribing, is difficult to say and probably differed in individual cases. Doctors tended to be more conservative in their management of older women and those whom they knew less well.

The urethral syndrome: a controlled evaluation.

It has long been considered that psychological factors play an important rôle in women with urinary tract symptoms. Where no significant infection can be demonstrated, psychological factors have been claimed as paramount to the extent that the 'irritable urethral syndrome' has been postulated as a parallel to the irritable bowel. This paper reports on a controlled study of psychological and menstrual problems in women presenting in family practice with urinary symptoms. Women were assessed by structured interview. Two groups of women took part: (A) 54 women with urinary symptoms, 15 of whom later proved to have significant bacterial infection on culture. (B) 21 women attending for contraceptive advice also agreed to participate in a comparison group. Women presenting with urinary tract symptoms had higher mean scores on psychological and menstrual measures than comparison women, regardless of the presence of demonstrable infection. Thus, psychological and menstrual symptoms appear to determine whether a woman who experiences urinary tract symptoms attends her doctor, regardless of whether significant infection is present. No evidence was found, for the existence of an irritable urethral syndrome, in which psychological factors are postulated as the predominant cause.

Problem drug use in a central London general practice.

OBJECTIVE: To describe the profile of problem drug users presenting in general practice and to determine whether they can be cared for in general practice. DESIGN: Study of consultations by problem drug users. SETTING: Central London general practice. SUBJECTS: 150 problem drug users presenting over two years. MAIN OUTCOME MEASURES: Stopping drug use, alterations in lifestyle, obtaining paid work, and stopping drug related crime. RESULTS: Of the 150 patients, 111 were men and 39 women, and 106 were unemployed. 121 patients used heroin, 112 of whom injected. 145 patients accepted a methadone reduction programme and 81 completed it. A further 25 were stabilised on reducing doses of methadone, until places became available for them as inpatients at drug dependency units or rehabilitation projects. CONCLUSION: Withdrawal programmes for patients who misuse drugs can be successfully managed in general practice.
