Screening for cervical intraepithelial neoplasia in north east Scotland shows fall in incidence and mortality from invasive cancer with concomitant rise in preinvasive disease.

OBJECTIVE--To assess the effect of screening for cervical intraepithelial neoplasia on the incidence of and mortality from invasive squamous cell carcinoma of cervix in north east Scotland and to discover why cases of invasive cancer still occur. DESIGN--(a) Analysis of data on cases of cervical intraepithelial neoplasia obtained from the cytology data bank; (b) analysis of data on 612 women presenting with invasive squamous cancer during 1968-91, obtained from cancer registry and hospital records; (c) analysis of death rates obtained from the registrar general''s (Scotland) annual reports, the Information Services Division of the Home and Health Department (Scotland), and local records for 1974-91; (d) case-control studies on 282 cases of invasive cancer and 108 deaths which occurred in 1982-91. Cases were matched with two controls both for age and for having a negative smear test result at the time of presentation of the case. SETTING--North east Scotland (Grampian region, Orkney, and Shetland). SUBJECTS--Women (n = 306,608) who had had cervical smear tests between 1960 and 1991. RESULTS--There had been a substantial increase in cases of cervical intraepithelial neoplasia grade III since 1982. The incidence of invasive cancer has fallen since the start of screening in 1960, the fall occurring mainly in the well screened age group 40-69 years. There was a rise in women aged under 40 and over 70. Women with invasive disease seen between 1982 and 1991 mostly presented at stage I. Of these, half were unscreened, one third were poorly screened, 11% were found in retrospect to have had abnormal cells, 3% had recurrence of disease after treatment for cervical intraepithelial neoplasia grade III, and 3% were lost to follow up. Death rates had fallen, most noticeably in women aged 45-64, who had had the opportunity to be screened and rescreened. There was a disturbing rise in deaths among women under 45. Most deaths (65%) occurred in unscreened women. Case-control studies showed that the longer the time and absence of a smear test before presentation the higher was the risk of invasive cancer and of death. CONCLUSIONS--Screening has been effective in reducing the incidence of and mortality from cervical cancer in north east Scotland. Most cases and deaths occurred in unscreened women or in those who had had few smears at long intervals. An increase in cases of cervical intraepithelial neoplasia grade III in women screened for the first time occurred during 1982-91.     

Prognostic trees to aid prognosis in patients with cutaneous malignant melanoma. Scottish Melanoma Group.

OBJECTIVES--To design user friendly guides to prognosis for patients who have had invasive primary cutaneous malignant melanomas surgically excised. DESIGN--Adaptation of the classification tree method was used to derive prognostic trees for four different subgroups of malignant melanoma patients in whom known and possible prognostic variables interacted in different ways. SETTING--Scotland. SUBJECTS--Statistical modelling for prognostic trees was based on 1978 patients whose primary malignant melanoma was first diagnosed in 1979-86 for whom five year follow up and all relevant clinical pathological data were available. The resultant model was validated with 300 patients first diagnosed in 1987 for whom the same information was available. MAIN OUTCOME MEASURES--Actual and predicted rate of survival after diagnosis of primary cutaneous malignant melanoma. RESULTS--The four subgroups of patients were men and women with ulcerated and non-ulcerated cutaneous primary melanomas. Validation of the model showed excellent agreement between actual status of patients in the relevant subgroups and their status as predicted by the model. CONCLUSIONS--The prognostic trees are simple to use and give more accurate prognosis for individual patients than is currently available from tumour thickness alone.     

Contribution of general practitioner hospitals in Scotland.

The results of a survey of 64 Scottish general practitioner hospitals showed that in 1980 these hospitals contained 3.3% of available staffed beds in Scotland; 13.6% of the resident population had access for initial hospital care, and 14.5% of Scottish general practitioners were on their staffs. During the year of the survey they discharged 1.8% of all non-surgical patients, treated almost 100 000 patients for accidents and emergencies and 140 000 outpatients, and 4.4% of all deliveries in Scotland were carried out in the hospitals surveyed. Most communities which are served by general practitioner hospitals in Scotland are rural and on average are more than 30 miles from their nearest district general hospital. The contribution that these small hospitals make to the overall hospital workload has not previously been estimated. It has been shown nationally to be small but not inconsiderable . In terms of the contribution to the health care of the communities they serve it cannot and should not be underestimated.     

Influences on hospital admission for asthma in south Asian and white adults: qualitative interview study

ObjectiveTo explore reasons for increased risk of hospital admission among south Asian patients with asthma.DesignQualitative interview study using modified critical incident technique and framework analysis.SettingNewham, east London, a deprived area with a large mixed south Asian population.Participants58 south Asian and white adults with asthma (49 admitted to hospital with asthma, 9 not admitted); 17 general practitioners; 5 accident and emergency doctors; 2 out of hours general practitioners; 1 asthma specialist nurse.ResultsSouth Asian and white patients admitted to hospital coped differently with asthma. South Asians described less confidence in controlling their asthma, were unfamiliar with the concept of preventive medication, and often expressed less confidence in their general practitioner. South Asians managed asthma exacerbations with family advocacy, without systematic changes in prophylaxis, and without systemic corticosteroids. Patients describing difficulty accessing primary care during asthma exacerbations were registered with practices with weak strategies for asthma care and were often south Asian. Patients with easy access described care suggesting partnerships with their general practitioner, had better confidence to control asthma, and were registered with practices with well developed asthma strategies that included policies for avoiding hospital admission.ConclusionsThe different ways of coping with asthma exacerbations and accessing care may partly explain the increased risk of hospital admission in south Asian patients. Interventions that increase confidence to control asthma, confidence in the general practitioner, understanding of preventive treatment, and use of systemic corticosteroids in exacerbations may reduce hospital admissions. Development of more sophisticated asthma strategies by practices with better access and partnerships with patients may also achieve this.

What is already known on this topic

South Asian patients with asthma are at increased risk of hospital admission with asthma compared with white patientsNo consistent differences in severity or prevalence of asthma, prescribed drugs, or asthma education have been described, and interventions to reduce admission rates in Asian patients have met with variable success

What this study adds

Compared with white patients, south Asian patients admitted to hospital with asthma had less confidence to control asthma, were unfamiliar with the concept of preventive medication, and had less confidence in their general practitionersSouth Asian patients managed asthma attacks through family advocacy and without systematic changes in prophylaxis and without systemic corticosteroidsPatients reporting difficulty in accessing primary care during attacks were often south Asian     

Performance of skin biopsies by general practitioners.

OBJECTIVE--To evaluate and appraise skin biopsies performed by general practitioners and compare their performance with that of hospital doctors. DESIGN--Retrospective analysis of histology records. SETTING--University hospital. SUBJECTS--Records of 292 skin biopsy specimens obtained by general practitioners and 324 specimens obtained by general and plastic surgeons. MAIN OUTCOME MEASURES--Clinical and pathological diagnoses and completeness of excision. RESULTS--The number of specimens received from hospital surgeons and general practitioners increased over the study period; the proportion of specimens from general practitioners rose from 17/1268 (1.3%) in 1984 to 201/2387 (8.7%) in 1990. The range of diagnoses was similar among hospital and general practitioner cases, although malignancy was commoner in hospital cases (63/324 (19%) v 14/292 (5%) in general practitioner cases; chi 2 = 28, p less than 0.00001). Completeness of excision was less common among general practitioners than hospital surgeons (150/233 (3/15 malignant) v 195/232 (57/63); chi 2 = 22, p less than 0.00001). CONCLUSIONS--The increase in minor surgery has implications for the staffing and finance of histopathology departments. General practitioners must be given proper training in performing skin biopsies, and all specimens should be sent for examination.     

Integrated care for asthma: a clinical,social, and economic evaluation. Grampian Asthma Study of Integrated Care (GRASSIC)

OBJECTIVES--To evaluate integrated care for asthma in clinical, social, and economic terms. DESIGN--Pragmatic randomised trial. SETTING--Hospital outpatient clinics and general practices throughout the north east of Scotland. PATIENTS--712 adults attending hospital outpatient clinics with a diagnosis of asthma confirmed by a chest physician and pulmonary function reversibility of at least 20%. MAIN OUTCOME MEASURES--Use of bronchodilators and inhaled and oral steroids; number of general practice consultations and hospital admissions for asthma; sleep disturbance and other restrictions on normal activity; psychological aspects of health including perceived asthma control; patient satisfaction; and financial costs. RESULTS--After one year there were no significant overall differences between those patients receiving integrated asthma care and those receiving conventional outpatient care for any clinical or psychosocial outcome. For pulmonary function, forced expiratory volume was 76% of predicted for integrated care patients and 75% for conventional outpatients (95% confidence interval for difference -3.6% to 5.0%). Patients who had experienced integrated care were more likely to select it as their preferred course of future management (75% (251/333) v 62% (207/333) (6% to 20%)); they saved 39.52 pounds a year. This was largely because patients in conventional outpatient care consulted their general practitioner as many times as those in integrated care, who were not also visiting hospital. CONCLUSION--Integrated care for moderately severe asthma patients is clinically as effective as conventional outpatient care, cost effective, and an attractive management option for patients, general practitioners, and hospital consultants.     

Using clinicopathological analysis of general practitioner skin surgery to determine educational requirements and guidelines.

OBJECTIVE--To study the impact of skin surgery in general practice on the workload of a pathology laboratory and to identify what further training might be helpful. DESIGN--Analysis of skin biopsy specimens from general practitioners before and after their new contract to determine numbers of specimens, changes in diagnoses, adequacy of treatment of malignant tumours, and areas of low diagnostic accuracy. SETTING--District general hospital. SUBJECTS--All 1017 skin biopsy specimens from general practice for 15 months before and 12 months after the new general practitioner contract. RESULTS--The number of pathology specimens received increased from 16 to 65 per month (median = 6 submitted by each general practitioner in the post-contract year). The proportion of the more common pathological diagnoses was unchanged between the two periods, but the proportion of correctly diagnosed naevi, cysts, and seborrhoeic keratoses increased in the second. Although few diagnoses were overtly incorrect, accurate diagnosis of dermatofibromas and malignancies decreased after the contract, and the overall correct diagnosis rate for seborrhoeic keratoses, dermatofibromas, rashes, and malignancies was below 30%. Only nine out of 21 squamous cell carcinomas were adequately excised with tumour free margins, and follow up of malignant tumours may have been inadequate. CONCLUSIONS--Skin surgery in general practice has advantages but matters of concern are the increase in laboratory workload, the excision of some benign lesions, and the inappropriateness of biopsy of rashes. Squamous cell carcinoma and other malignant tumours submitted for pathological examination were often unsuspected and inadequately excised, and heightened suspicion is recommended. Pathology request forms may need redesigning to encourage provision of clinical details.     

Surgical considerations in the management of malignant melanoma of the ear

Malignant melanomas of the external ear are rare and are difficult lesions to treat because of the cosmetic importance and the reconstructive difficulty of their location. The literature suggests that these lesions have a worse prognosis than melanomas occurring elsewhere and that radical resection is the "correct" treatment. To clarify this issue, we examined 21 consecutive patients (19 male, 2 female) with malignant melanoma of the ear seen at the Yale-New Haven Hospital over the last 10 years. Nineteen patients had a diagnosis of primary malignant melanoma of the ear, one had a local recurrence, and one had an in-transit melanoma from an unknown primary site. The mean thickness of the lesions was 2.7 mm. Two patients had palpable nodes, which in both cases turned out to be histologically positive for tumor. All patients underwent local excision and reconstruction using chondrocutaneous or fasciocutaneous flaps or skin grafts. There was one local recurrence (0.5 mm original thickness); there were two patients with regional recurrences, both of whom died within a year with disseminated disease. Forty-three percent have been followed for 5 or more years and all are alive and free of disease. This suggests that malignant melanoma of the ear may be safely treated by conservative excision and reconstruction.     

Sources and patterns of referrals of oral cancer: role of general practitioners.

Referrals of patients with oral squamous cell carcinomas to an oral medicine clinic were assessed with regard to the sources, delays, and pattern of referrals from general medical practitioners and general dental practitioners. Slightly more patients were referred by dental practitioners than by medical practitioners, but general medical practitioners were far more likely to see advanced tumours and to request an urgent second opinion or suggest a diagnosis of malignant disease. The greatest delay overall was caused by the patients in seeking advice from their practitioner, particularly those who attended a general medical practitioner. Both groups of practitioners requested a hospital opinion within roughly a month--a reasonable interval. Subsequent delays were minimal. Delays occur mainly because the patients are slow in seeking professional advice and, in general, do not appear to have been reduced over the decade since a previous British study on referral patterns was carried out. This study emphasises the importance of educating patients about oral cancer since it is they who appear to be mainly responsible for the delays in diagnosis. The results also help to dispel the myth that general medical practitioners might be less competent at diagnosis and referral of patients with oral cancer than are dental practitioners, though we are aware of misdiagnoses from both groups.     

Cost effectiveness of treating primary care patients in accident and emergency: a comparison between general practitioners,senior house officers,and registrars.

OBJECTIVES--To compare outcome and costs of general practitioners, senior house officers, and registrars treating patients who attended accident and emergency department with problems assessed at triage as being of primary care type. DESIGN--Prospective intervention study which was later costed. SETTING--Inner city accident and emergency department in south east London. SUBJECTS--4641 patients presenting with primary care problems: 1702 were seen by general practitioners, 2382 by senior house officers, and 557 by registrars. MAIN OUTCOME MEASURES--Satisfaction and outcome assessed in subsample of 565 patients 7-10 days after hospital attendance and aggregate costs of hospital care provided. RESULTS--Most patients expressed high levels of satisfaction with clinical assessment (430/562 (77%)), treatment (418/557 (75%)), and consulting doctor''s manner (434/492 (88%)). Patients'' reported outcome and use of general practice in 7-10 days after attendance were similar: 206/241 (85%), 224/263 (85%), and 52/59 (88%) of those seen by general practitioners, senior house officers, and registrars respectively were fully recovered or improving (chi2 = 0.35, P = 0.840), while 48/240 (20%), 48/268 (18%), and 12/57 (21%) respectively consulted a general practitioner or practice nurse (chi2 = 0.51, P = 0.774). Excluding costs of admissions, the average costs per case were 19.30 pounds, 17.97 pounds, and 11.70 pounds for senior house officers, registrars, and general practitioners respectively. With cost of admissions included, these costs were 58.25 pounds, 44.68 pounds, and 32.30 pounds respectively. CONCLUSION--Management of patients with primary care needs in accident and emergency department by general practitioners reduced costs with no apparent detrimental effect on outcome. These results support new role for general practitioners.     

Evaluation of nodal patterns for melanoma of the ear

Treatment of malignant melanoma of the external ear presents unique challenges. Because of the significant debate regarding the efficacy and validity of using sentinel lymph node mapping for the treatment of ear melanomas, data for a population of patients with melanomas of the ear who underwent surgical excision and reconstruction were reviewed to determine the efficacy of sentinel node mapping. A retrospective chart review of cases treated by a single surgical oncologist was performed. All patients who were treated for malignant melanomas and required reconstruction of the external ear by the plastic surgical service between 1995 and 2001 were identified. Nineteen patients were selected, of whom nine underwent sentinel node mapping. The average age of the patients was 65.2 years. Evaluation of melanoma depth, medical history, surgical margins, lymph node metastasis, and recurrence was performed. Lymphoscintigraphy with technetium-99-sulfur colloid and 1% Lymphazurin (isosulfan blue; Zenith Parenterals, Rosemont, Ill.) demonstrated widely variable lymphatic drainage patterns. The lower tail of the parotid gland and the upper cervical area were the two most common locations. The average number of sentinel nodes identified and removed was 3.7. The average Breslow thickness for these patients was 2.3 mm. None of these patients demonstrated micrometastatic disease in their sentinel nodes. The most common reconstructive procedure after surgical resection was the use of rotational advancement flaps. Localization of radioactivity, as detected with external technetium-99 scanning, was the most reliable method for detection of the sentinel lymph node basins and the individual nodes. The average value for the primary injection site was 8375 counts per second, and the average value for the nodes removed was 973.5 counts per second. Of the nine patients who underwent sentinel lymph node mapping, only one, with an initial lesion depth of 5 mm, developed a local recurrence. The average follow-up period in this study was 21 months (range, 12 to 79 months). All patients in this study were evaluated at least 1 year after the initial surgical resection. Patients were monitored by the same surgical oncologist every 3 months for the first 2 years. Little can be found in the literature regarding the efficacy of sentinel node biopsies for ear melanomas. Larger studies are indicated; however, it seems that this method is practical for designing therapeutic methods for patients with melanoma of the ear.     

General practitioner response to elderly patients discharged from hospital.

OBJECTIVE--To determine the effect of discharge information given to general practitioners on their management of newly discharged elderly patients. DESIGN--A random sample of 133 elderly patients who had unplanned readmission to a district general hospital within 28 days of discharge was compared with a matched control sample of patients who were not readmitted. Information was gathered from the hospital, the patients, the carers, and the general practitioners about the information that the hospital had sent the general practitioner and the general practitioners'' response to this information. SETTING--All specialties in a district general hospital. PATIENTS--266 Patients aged over 65 representative in the main demographic indices of the population of elderly patients admitted to hospital. RESULTS--Ten weeks after discharge the doctors had received notice of discharge about 169 of the patients, but fewer than half the discharge notices were received within the first week. General practitioners were dissatisfied with the information in 60 cases. A general practitioner visited 174 of the patients after their discharge from hospital and three quarters of the visits took place within two weeks of the discharge. These visits were more likely to have been initiated by patients or families than by the doctor, and this was not influenced by the doctor receiving notice of the patient''s discharge. Older patients and those who had carers were the most likely to be visited. Nearly half of the carers were dissatisfied with some aspect of general practitioner care, problems with home visiting being the commonest source of complaint. CONCLUSIONS--Hospital communications to general practitioners about the discharge of elderly patients still cause concern, particularly in the time they take to arrive. Written instruction to vulnerable elderly patients asking them to inform their general practitioner of the discharge might be helpful. Carers complained of lack of support, and it is clearly important for someone (either the general practitioner or another health worker) to visit elderly people shortly after their discharge.     

Alternatives to hospital care: what are they and who should decide?

OBJECTIVE--To examine potential for alternatives to care in hospitals for acute admissions, and to compare the decisions about these alternatives made by clinicians with different backgrounds. DESIGN--Standardised tool was used to identify patients who could potentially be treated in an alternative form of care. Information about such patients was assessed by three panels of clinicians: general practitioners without experience of general practitioner beds, general practitioners with experience of general practitioner beds, and consultants. SETTING--One hospital for acute admissions in a rural area of the South and West region of England. SUBJECTS--Of 620 patients admitted to specialties of general medicine and care of the elderly, details of 112 were assessed by panels. MAIN OUTCOME MEASURES--Proportion of hospitalised patients who could have received alternative care and identification of most appropriate alternative form of care. RESULTS--Both general practitioner panels estimated that between 51 and 89 of the hospitalised patients could have received alternative care (equivalent to 8-14% of all admissions). Consultants estimated that between 25 and 55 patients could have had alternative care (5.5-9% of all admissions). General practitioner bed and urgent outpatient appointment were the main alternatives chosen by all three panels. CONCLUSION--About 10% of admissions to general hospital might be suitable for alternative forms of care. Doctors with different backgrounds made similar overall assessments of most appropriate forms of care.     

Evaluation of aid to diagnosis of pigmented skin lesions in general practice: controlled trial randomised by practice

Objectives To determine whether an aid to the diagnosis of pigmented skin lesions reduces the ratio of benign lesions to melanomas excised in general practice.Design Controlled trial randomised by practice.Setting General practices in Perth, Western Australia.Participants 468 general practitioners in 223 practices.Interventions Intervention practices were given an algorithm and instant camera to assist with the diagnosis of pigmented skin lesions. All practices were given national guidelines on managing melanoma.Main outcome measures Ratio of benign pigmented lesions to melanomas excised. Analyses conducted with and without inclusion of seborrhoeic keratoses.Results At baseline the ratios of benign to malignant lesions were lower in the intervention group than in the control group. During the trial period the ratios were higher in the intervention group (19:1 v 17:1 without seborrhoeic keratoses and 29:1 v 26:1 with seborrhoeic keratoses). After adjustment for patients'' age, sex, and socioeconomic status, the ratio was 1.02 times higher (95% confidence interval 0.68 to 1.51, P = 0.94) in the intervention group when seborrhoeic keratoses were not included and 1.03 times higher (0.71 to 1.50, P = 0.88) when seborrhoeic keratoses were included. General practitioners in the intervention group were less likely than those in the control group to excise the most recent pigmented skin lesion they managed (22% v 48%, P < 0.001) and to refer the patient to a specialist (16% v 27%, P = 0.06).Conclusions Provision of the algorithm and camera did not decrease the ratio of benign pigmented skin lesions to melanomas excised by general practitioners.     

Is histological examination of tissue removed by general practitioners always necessary? Before and after comparison of detection rates of serious skin lesions.

OBJECTIVES: To examine whether histological examination of all tissue removed by general practitioners in minor surgery increases the rate of detection of clinically important skin lesions, and to assess the impact of such a policy on pathologists'' workload. DESIGN: Before and after comparison. SETTING: Stratified random sample of 257 general practitioner partnerships from the catchment areas of 19 English pathology laboratories. SUBJECTS: Tissue removed in minor surgery by general practitioners during the control period (September 1992 to February 1993) and intervention period (September 1993 to February 1994). INTERVENTION: General practitioners referred to their local pathology laboratory all solid tissue removed in all minor surgery, irrespective of their previous policy. MAIN OUTCOME MEASURES: Numbers of specimens referred for histology by general practitioners during intervention and control periods; numbers of primary malignant melanomas, non-melanoma malignancies, premalignant lesions, and benign lesions. RESULTS: 257/330 partnerships participated (response rate 78%). During the intervention period 5723 specimens were sent, compared with 4430 during the control period. The referral rate increased by an estimated 1.34 specimens per 1000 patient years (95% confidence interval 0.93 to 1.76, P < 0.0001). General practitioners sent 204 specimens that were malignant (including 16 malignant melanomas) in the control period and 188 that were malignant (including 15 malignant melanomas) during the intervention period (change in total number of malignancies, -1.0 per 100,000 patient years (-5.9 to 3.8, non-significant). CONCLUSIONS: The intervention was associated with a substantial increase in laboratory workload, all of which was accounted for by increases in non-serious lesions. This observation should be taken into account when considering the merits of a policy requiring histological examination in every case.     

One thousand heart attacks in Grampian: the place of cardiopulmonary resuscitation in general practice.

The outcome of 1011 heart attacks in patients under the care of general practitioners who practised cardiopulmonary resuscitation and were equipped with defibrillators is reported. The 28 day mortality was 36% (367 patients), and 59% of deaths occurred outside hospital. The general practitioner was the first medical contact in 92% of heart attacks and was equipped with a defibrillator in 80% of such calls. Fifty six patients had a cardiac arrest in the presence of a general practitioner, and resuscitation was attempted in 47 cases, representing 5% of all calls for heart attacks. Twenty one (45%) resuscitated patients reached hospital alive, and 13 (28%) survived to leave hospital. The opportunities for cardiopulmonary resuscitation in general practice occur sufficiently often to warrant training and equipping general practitioners for advanced life support. The results of resuscitation by general practitioners working alone compare favourably with those of mobile coronary care units based in hospitals.     

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.     

Audit of public education campaign to encourage earlier detection of malignant melanoma.

OBJECTIVES--To evaluate a public campaign to encourage earlier referral and treatment of primary cutaneous malignant melanoma and thus reduce mortality related to melanoma. DESIGN--Production and distribution of educational material aimed at adults. Update information sent to general practitioners before campaign. Analysis of data on melanoma before and after campaign in June 1985. SETTING--West of Scotland, population 2.7 million. MAIN OUTCOME MEASURES--Total numbers of referrals per month to melanoma clinic, numbers of melanomas diagnosed, change in distribution of thickness, and mortality before and after introducing the campaign. RESULTS--Referrals to the pigmented lesion clinic increased by 278%, from five a week in June-July 1984 to 19 a week in June-July 1985. Twice as many women as men were referred to the clinic (49% of referrals were of women aged under 65). The numbers of newly diagnosed primary cutaneous melanoma were 63 (12/month) in January-May 1985 and 146 (21/month) in June-December 1985, an increase of 131%. The percentage of tumours detected that were less than 1.5 mm thick rose significantly by 16% (95% confidence interval 11% to 19%), from 38% (328) in 1979-84 to 54% (592) in 1985-9. Mortality began to fall in women from 1988. CONCLUSIONS--The public education campaign succeeded in reducing the absolute number of thick tumours and melanoma related mortality in women.     

Home care for patients with suspected myocardial infarction: use made by general practitioners of a hospital team for initial management.

Two hundred and sixty three general practitioners were offered the use of a hospital based service consisting of a medical senior house officer, a nurse attached to a coronary care unit, and a specially equipped ambulance estate car to help with the initial management of patients with suspected myocardial infarction who might be suitable for home care. One hundred and sixty nine general practitioners registered as potential users of this service; during 22 months they called the hospital team to see 271 patients, 235 of whom the team suspected had indeed suffered a myocardial infarction. During the same period, however, these general practitioners also admitted 317 patients with suspected myocardial infarction directly to hospital. Other general practitioners admitted 323 patients and deputising doctors 258. A further 529 patients with suspected infarction were admitted without the intervention of a general practitioner. Of the patients seen by the team, 54 required immediate admission to hospital; 17 of the remaining patients who initially appeared suitable for home care later required admission to hospital. In a large city such as Nottingham the provision of hospital based facilities to help general practitioners with home management is unlikely to make an appreciable impact on the overall pattern of care of patients with suspected myocardial infarction.
