Trends in acute admissions: a study of one English district general hospital.

BACKGROUND: The aim of the study was to determine whether significant daily and hourly variations in acute admissions to hospital were evident over time, and to determine whether significant changes in patient and management characteristics had occurred over time. METHODS: Time-trend and cross-section analysis of admissions was carried out, for samples between 1986 and 1995, using manual records from the transit ward, Doncaster Royal Infirmary. RESULTS: Mean daily admissions at weekends were significantly lower than those occurring during the working week. During the day, the admission rate peaked at around noon and gradually declined thereafter. Patients arriving during the night tended to be younger and were more likely to be male. Age was a significant predictor of subsequent patient management following arrival. Overall, the number and mean age of arriving patients had increased by the end of the investigation period, although the proportion of patients being sent home from the transit ward did not vary over time.

Morbidity from asthma in relation to regular treatment: a community based study.

BACKGROUND: The extent to which asthma morbidity in the community occurs in patients who are having relatively little treatment or in those on step 3 or above of the British asthma management guidelines is uncertain. We have looked at this in a community population in southern Nottinghamshire. METHODS: A cross sectional review of treatment in all patients over the age of four with diagnosed asthma was carried out in five large general practices (population 38 865) in 1995/6 using computerised general practice records. The patients' usual treatment was obtained from prescription data and categorised by the appropriate step on the British guidelines on asthma management. Two measures of morbidity, the request for 10 or more short acting beta agonist inhalers a year or the need for a course of oral corticosteroids in the last year, were related to the regular treatment of the patients. RESULTS: Of the 3373 patients (8. 7%) given a diagnosis of asthma, the percentage on steps 1, 2, 3, 4, and 5 of treatment were 54%, 22%, 11%, 3.6%, and 1%, respectively, with a further 8% having had no treatment. During the past year 13. 6% had been prescribed 10 or more beta agonist inhalers and 12.5% had received at least one course of oral corticosteroids. Both measures occurred more frequently in patients taking more prophylactic treatment (step 3 or above). Nevertheless, because most patients were on steps 1 and 2 of the treatment guidelines, more than half the patients requiring high doses of inhaled beta agonists or a course of oral prednisolone came from those taking low dose or no regular inhaled corticosteroid. CONCLUSIONS: Evidence of morbidity from asthma was found in many patients taking little or no prophylactic medication and this should be amenable to improved education. A different approach may be needed for patients with continuing morbidity who are already taking higher doses of prophylactic medication.

Viewing the kaleidoscope of health systems through a patient-centred prism.

I ought to start by giving my credentials for writing this commentary. I have a marked aversion to outsiders with limited first-hand experience telling me about the British National Health Service. This is especially so when their questions and comments raise issues that make me feel uncomfortable.

Depression as a risk factor for ischaemic heart disease in men: population based case-control study.

OBJECTIVE: To determine the relation between depression, anxiety, and use of antidepressants and the onset of ischaemic heart disease. DESIGN: Population based case-control study. SETTING: All 5623 patients registered with one general practice. SUBJECTS: 188 male cases with ischaemic heart disease matched by age to 485 male controls without ischaemic heart disease; 139 female cases with ischaemic heart disease matched by age to 412 female controls. MAIN OUTCOME MEASURE: Adjusted odds ratios calculated by conditional logistic regression. RESULTS: The risk of ischaemic heart disease was three times higher among men with a recorded diagnosis of depression than among controls of the same age (odds ratio 3.09; 95% confidence interval 1.33 to 7.21; P=0.009). This association persisted when smoking status, diabetes, hypertension, and underprivileged area (UPA(8)) score were included in a multivariate model (adjusted 2.75; 1.13 to 6.69; P=0.03). Men with depression within the preceding 10 years were three times more likely to develop ischaemic heart disease than were the controls (3.13; 1.27 to 7.70; P=0.01). Men with ischaemic heart disease had a higher risk of subsequent depression [corrected] than men without ischaemic heart disease (adjusted 2.34; 1.34 to 4.10; P=0.003). Depression was not a risk factor for ischaemic heart disease in women on multivariate analysis (adjusted 1.34; 0.70 to 2.56; P=0.38). Anxiety and subsequent ischaemic heart disease were not significantly associated in men or women. CONCLUSION: Depression may be an independent risk factor for ischaemic heart disease in men, but not in women.

Do minutes count? Consultation lengths in general practice.

OBJECTIVE: To document the variability in consultation length and to examine the relative weight of different kinds of characteristics (of the patients, of the general practitioner (GP), or of the practice) in affecting consultation length, and, thus, to assess whether consultation length can legitimately be used as a quality marker. DESIGN: A multilevel statistical analysis of 836 consultations across 51 GPs in ten practices. SETTING AND SUBJECTS: Ten general practices across four regions in England with varying list sizes, number of partners and fundholding status. MAIN OUTCOME MEASURES: Length of time face-to-face with patients in consultation measured in minutes and fractions of minutes. RESULTS: There is substantial inter-practice variation in consultation length, from a mean of 5.7 minutes to one of 8.5 minutes. In some practices the longest average GP consultation time is about twice that of the shortest. Trainees and new partners spend, on average, about 1 minute less than their longer-serving colleagues. Consultation lengths for individual GPs range from a mean of 4.4 minutes to 11 minutes. Late middle-aged women (55-64 years) receive the longest consultations, followed by elderly people, with children receiving the shortest consultations. The number of topics raised affects the length of the consultation by about 1 minute per additional topic. When female patients consult female GPs, approximately 1 minute is added to the average consultation. A significant fraction of the variability in consultation lengths can be explained in terms of characteristics of patients, of GPs and of practices. CONCLUSIONS: The fact that there is little unexplained variation in GP consultation lengths that might be attributable to variations in quality (i.e. GP-related) throws doubt on the proposition that length of consultation can be used as a marker for quality of consultation in general practice.

Are spouses of patients with hypertension at increased risk of having hypertension? A population-based case-control study.

BACKGROUND: Studies of couples, who tend to share an environment but are genetically dissimilar, can shed light on the contribution of environmental factors to hypertension. There has been renewed interest in these environmental factors following the re-analysis of the INTERSALT study. AIM: To determine whether patients whose spouses have hypertension are at increased risk of hypertension, using a population-based case-control study. METHOD: The total study population consisted of all 3923 patients over 30 years old registered with one general practice. Male cases with hypertension were matched to male controls without hypertension. Female cases with hypertension were matched to female controls without hypertension. The variables were: diagnosed hypertension; having a spouse with diagnosed hypertension; age; sex; weight; height; body-mass index; couple status; diabetes; and systolic and diastolic blood pressure readings. RESULTS: On multivariate analysis, when age, body-mass index, diabetes, couple status, and having a blood pressure reading were included, men whose spouses had hypertension had a two-fold increased risk of hypertension (adjusted odds ratio (OR) 2.24; 95% CI 1.77-2.72; P = 0.001). Similarly, on multivariate analysis, women whose spouses had hypertension had a two-fold increased risk of hypertension (adjusted OR = 2.23; 95% CI 1.75-2.72; P = 0.001). The risk for both male and female subjects persisted after adjustment for other variables. There was a significant correlation between systolic (r = 0.41; P < 0.0001) and diastolic (r = 0.25; P < 0.0001) blood pressures between spouse pairs. CONCLUSION: The independent association between having a spouse with hypertension and increased risk of hypertension supports the view that there are significant environmental factors in the aetiology of hypertension. The finding has implications for the screening and treatment of hypertension in primary care.

The effect of deprivation on variations in general practitioners' referral rates: a cross sectional study of computerised data on new medical and surgical outpatient referrals in Nottinghamshire.

OBJECTIVE: To determine the effect of deprivation on variations in general practitioners' referral rates using the Jarman underprivileged area (UPA(8)) score as a proxy measure. DESIGN: Cross sectional survey of new medical and surgical referrals from general practices to hospitals (determined from hospital activity data). SETTING: All of the 183 general practices in Nottinghamshire and all of the 19 hospitals in Trent region. MAIN OUTCOME MEASURES: The relation between the referral rates per 1000 registered patients and the practice population's UPA(8) score (calculated on the basis of electoral ward), with adjustment for the number of partners, percentage of patients aged over 65 years, and fundholding status of each practice. RESULTS: There was a significant independent association between deprivation, as measured by the UPA(8) score, and high total referral rates and high medical referral rates (P < 0.0001). The UPA(8) score alone explained 23% of the total variation in total referral rates and 32% of the variation in medical referral rates. On multivariate analysis, where partnership size, fundholding status, and percentage of men and women aged over 65 years were included, the UPA(8) score explained 29% and 35% of the variation in total and medical referral rates respectively. CONCLUSION: Of the variables studied, the UPA(8) score was the strongest predictor of variations in referral rates. This association is most likely to be through a link with morbidity, although it could reflect differences in patients' perceptions, doctors' behaviour, or the use and provision of services.

Are patients who present late with cancer registered with low referring practices?

This study examines whether a clinical outcome (stage of breast or bowel cancer at referral) was related to variations in GP referral rates. A multivariate analysis of breast and bowel cancer patients referred from 183 Nottinghamshire practices during 1993 showed no adverse outcome associated with low GP referral rates. Variables included in the analysis were total and surgical referral rates, fundholding status, UPA(8) score of the practice, partnership size, and age and sex of the referred patient.

Use of oral corticosteroids in the community and the prevention of secondary osteoporosis: a cross sectional study.

OBJECTIVE: To determine the prevalence of continuous use of oral steroids in the general population, the conditions for which they are prescribed, and the extent to which patients taking oral steroids are taking treatment to prevent osteoporosis. DESIGN: A cross sectional study with a four year retrospective review of drug treatment. SETTING: Eight large general practices in central and southern Nottinghamshire. SUBJECTS: A population of 65,786 patients (52% women) registered with a general practitioner during 1995. RESULTS: 303 patients (65% (197) women) aged 12-94 years were currently taking "continuous" (for at least three months) oral corticosteroid treatment. This figure represents 0.5% of the total population and 1.4% (245/17 114) of patients aged 55 years or more (1.7% (166/9601) of women). The usual steroid was prednisolone (97% (294/303)), the mean dose was 8.0 mg/day, and the median duration of oral steroid treatment determined in 149 patients was three years. The most common conditions for which continuous oral steroids were prescribed were rheumatoid arthritis (23% (70)), polymyalgia rheumatica (22% (66)), and asthma or chronic obstructive airways disease (19% (59)). Only 41 (14%) of the 303 patients taking oral steroids had received treatment for the prevention of osteoporosis over the past four years. Although 37 of the 41 patients were women, only 10% (18/181) of the women over 45 years taking continuous oral corticosteroids were currently taking hormone replacement therapy. CONCLUSIONS: If our figures are typical then they suggest that over 250,000 people in the United Kingdom are taking continuous oral steroids and that most of these are taking no prophylaxis against osteoporosis.

Practicality of recording patient ethnicity in general practice: descriptive intervention study and attitude survey.

OBJECTIVE: To assess the feasibility of recording patient ethnicity in primary care using the Office of Population Censuses and Surveys classification. DESIGN: A descriptive intervention study and attitude survey in random samples of adults and primary care staff in randomly selected practices. SETTING: Eight practices in Lincolnshire and seven in Leicester. SUBJECTS AND METHODS: When patients were asked their ethnicity by general practitioners, nurses, or receptionists data were collected for 863 of a possible 880 patients. Of 750 patients sent a questionnaire about their attitudes towards the collection of such data 489 responded. Ninety five primary care staff completed a similar questionnaire. MAIN OUTCOME MEASURES: Time taken to record a patient's ethnicity; attitudes of patients and staff towards such recording, including who should ask, who can respond for others, and whether data can be shared with secondary care. RESULTS: Recording the data took less than a minute for three quarters of patients, but even this would need an average of a week of receptionist time per general practitioner. 72% of patients and 57% of staff agreed that ethnic data could be shared with secondary care, and 73% of patients and 60% of staff felt that the data should probably be collected in general practice. CONCLUSIONS: Ethnicity recording in general practice is feasible and acceptable. Nevertheless, the role of ethnic data in assessing health need in primary care, an adequate recording system, and evidence that recording offers benefits greater than the costs need to be established.
