Does increased use of private health care reduce the demand for NHS care? A prospective survey of general practice referrals

BACKGROUND: The use of the private sector for health care is increasing, but it is unclear whether this will reduce demand on the NHS. The aim of this study was to examine the relationship between private and NHS outpatient referral rates accounting for their association with deprivation. METHODS: This is a prospective survey of general practitioner referrals to private and NHS consultant-led services between 1 January and 31 December 2001 from 10 general practices in the Trent Focus Collaborative Research Network, United Kingdom. Patient referrals were aggregated to give private and NHS referral rates for each electoral ward in each practice. RESULTS: Of 17,137 referrals, 90.4 percent (15,495) were to the NHS and 9.6 percent (1642) to the private sector. Private referral rates were lower in patients from the most deprived fifth of wards compared with the least deprived fifth (rate ratio 0.25, 95 percent CI 0.15 to 0.41, p < 0.001), whereas NHS referral rates were slightly higher in patients in the most deprived fifth of wards (rate ratio 1.18, 95 percent CI 0.98 to 1.42, p = 0.08) both after age standardisation and adjustment for practice. The NHS referral rate was significantly higher (rate ratio 1.40, 95 percent CI 1.15 to 1.71, p = 0.001) in wards with private referral rates in the top fifth compared with the bottom fifth after adjustment for deprivation and practice. CONCLUSIONS: Increased private health care activity does not reduce the demand for NHS care: NHS and private referral rates were positively associated with each other after adjusting for age, deprivation and practice.     

Socio-economic deprivation is associated with increased proximity to general practices in England: an ecological analysis

BACKGROUND: As health status is consistently negatively correlated with socio-economic deprivation, the need for health services is generally assumed to be greater in more deprived communities. The Inverse Care Law predicts that access to good quality primary care services in more deprived wards will be less than that in affluent wards. However, the relationship between deprivation and geographical proximity to health services has received little attention. METHODS: We investigated the relationship between geographical proximity to general practices and a number of markers of socio-economic deprivation at the electoral ward level in the North East of England using various domains of the Index of Multiple Deprivation 2000 (IMD2000). RESULTS: More deprived wards, as measured by the employment, education and income domains of the IMD2000, had greater proximity to general practices, as measured by the access domain of the IMD2000, than affluent wards. This results held in both urban and rural wards. CONCLUSIONS: Contrary to our expectations and the predictions of the Inverse Care Law, geographical proximity to general practices was greater in more deprived, compared to more affluent wards. However, geographical proximity to services does not necessarily ensure that services will be accessed or that they are of good quality.     

Do rates of hospital admission for falls and hip fracture in elderly people vary by socio-economic status?

OBJECTIVE: To determine the relationship between hospital admissions for falls and hip fracture in elderly people and area characteristics such as socio-economic deprivation. STUDY DESIGN: Ecological study of routinely collected hospital admissions data for falls and hip fracture in people aged 75 years or over for 1992-1997, linked at electoral ward level with characteristics from census data. METHODS: In total, 42,293 and 17,390 admissions were identified for falls and hip fracture, respectively, from 858 electoral wards in Trent. Rate ratios (RRs) for hospital admissions for falls and hip fracture were calculated by the electoral wards' Townsend score divided by quintiles. RRs were estimated by negative binomial regression and adjusted for the ward characteristics of age, gender, ethnicity, rurality, proportion of elderly people living alone and distance from hospital. RESULTS: There was a small but statistically significant association at electoral ward level between hospital admissions for falls and the Townsend score, with the most deprived wards having a 10% higher admission rate for falls compared with the most affluent wards (adjusted RR 1.10, 95% CI 1.01-1.19). No association was found between hospital admission for hip fracture and deprivation (adjusted RR 1.05, 95% CI 0.95-1.16). CONCLUSION: There is some evidence of an association at electoral ward level between hospital admissions for falls and socio-economic deprivation, with higher rates in deprived areas. No such association was found for hip fracture. Further work is required to assess the impact of interventions on reducing inequalities in hospital admission rates for falls in elderly people.     

Contact between people with learning disability and general practitioners: a cross-sectional case note survey.

BACKGROUND: This paper describes primary care consultation rates in a sample of people with learning disability. The study was carried out as part of a wider survey of primary care for this population group in response to concerns over quality of care and debate between general practitioners (GPs) and the local health authority over the need for additional remuneration for caring for people with learning disability. Estimates of consultation rates in the literature to date are conflicting and we sought to provide local data on the number and type of contacts with the primary care teams to inform this debate. METHOD: A primary care case note review was carried out of 112 people with learning disability aged over 18, identified from an administrative sample of 967 people known to health and social services. Contact rates (with practice nurses or GPs) were calculated and indirectly standardized for age using data from the fourth National Morbidity Survey in General Practice (MSGP4). RESULTS: Standardized consultation ratio in men was 156 (95 per cent confidence interval (CI) 142-172), in women was 111 (95 per cent CI 102-121) and for both sexes was 127 (95 per cent CI 120-135). Average contact rate was 4.6 per person per year. Eighty per cent of contacts were with GPs. Eighteen per cent (95 per cent CI 11-25 per cent) of subjects consulted, on average, more than once every two months. Limited information on underlying cause of learning disability and severity was available. Consultation rates were independent of age and sex, and were not increased in people with Down's syndrome or epilepsy compared with the rest of the sample population. Consultation rates were highest in people living in staffed group homes (p = 0.01). The presence of special arrangements between practices and residential facilities did not appear to increase service contact, but this finding is prone to measurement bias. CONCLUSIONS: Contrary to the findings of previous studies, people with learning disability consult primary care teams more frequently than the general population. However, this should not be taken as supporting calls for additional resources without addressing the effectiveness and appropriateness of health care offered.     

Costs and remuneration for cervical screening in general practice in the west of Scotland

OBJECTIVES: To investigate associations between costs and remuneration for cervical screening in general practice in relation to skill mix, features of practice structure and deprivation levels in the local area; and, to identify efficient policies for organising cervical screening in general practice. METHOD: Questionnaire survey and interview study in 87 general practices in Greater Glasgow Health Board an area in the west of Scotland which covers a socio-economically varied population. The main outcome measures were remuneration to cost ratios (RCRs) for cervical screening and their natural logarithms (logRCRs). RESULTS: Both the costs of cervical screening and RCRs varied widely between the 87 practices taking part. RCRs ranged from 0.29 to 14.67 (mean 2.64, median 2.18, interquartile range 1.15-2.98). Twenty-one per cent (18) of practices earned less than they spent on the organisation of screening, whilst 9% (8) of practices had PCRs of more than 5:1. RCRs were significantly lower if medical staff were involved in either taking smears or dealing with results. RCRs did not vary by social deprivation score, despite uptake being lower in practices in more deprived areas. This was explained by nurses working in practices in deprived areas being more likely to take smears than nurses working in more affluent areas. Sensitivity analyses were undertaken, altering key time and cost assumptions. As a result, the absolute values of the RCRs changed, although the overall pattern of association did not, with the exception of doctor involvement in processing results which was no longer significant when average general practitioners' income was substituted for locum rates. CONCLUSIONS: Practices in deprived areas may be responding to greater pressure of work by making optimal use of skill mix within the primary health care team. A more graduated incentive payment scheme may more fairly reward practices in deprived areas which are less likely to achieve 80% uptake due to relatively intractable features of practice structure. Assuming that practice nurses provide an equivalent quality of service to that provided by general practitioners, results suggest that doctor-nurse substitution would be cost-effective for general practice based cervical screening. Resource savings (principally doctor's time) could be redeployed to other areas of primary health care.     

Inequalities in access to diabetes care: evidence from a historical cohort study

OBJECTIVE: To establish which factors predict attendance at a hospital diabetes clinic and for diabetes review in general practice. DESIGN: A historical cohort study of individuals with diabetes identified from general practice records. Information on service contacts and other clinical, social, and demographic variables was collected from general practice records and postal questionnaires. SETTING: Seven Leicestershire general practices. SUBJECTS: Individuals registered with study practices who had a diagnosis of diabetes made before 1990. MAIN OUTCOME MEASUREMENTS: Attendance at a hospital diabetes clinic or for a documented diabetes review in general practice at least once between 1990 and 1995. RESULTS: 124 (20%) had at least one recorded diabetes review in general practice and 332 (54%) attended a hospital diabetes clinic at least once. The main predictors of attending a hospital clinic were younger age, longer duration of diabetes, and treatment with insulin. Access to a car (OR 1.34, 95% CI 1.06 to 1.71), home ownership (OR 1.48, 95% CI 1.14 to 1.58) and a non-manual occupation (OR 1.56, 95% CI 1.09 to 2.24) were all associated with an increased likelihood of attending, although living in a less deprived area was not. The main predictors of attending for review in general practice were older age, less co-morbidity, and being white. Living in a more deprived area was related to a reduced chance of review in general practice (OR 0.81, 95% CI 0.76 to 0.86) while individual socioeconomic indicators were not. CONCLUSIONS: Whilst an indicator of area deprivation predicts reduced likelihood of review in general practice, individual indicators predict reduced likelihood of attending outpatients. This suggests a need for different approaches to tackling inequalities in access to care in primary and secondary care settings.     

High rates of primary care and emergency department use among injection drug users in Vancouver

BACKGROUND: Frequent use of emergency rooms by injection drug users (IDUs) has been attributed to a lack of access to primary care and barriers to health services. Using a community-based sample of IDUs, we examined rates of primary care and emergency room use among IDUs and identified correlates of frequent emergency department use. METHODS: From January to November 2003, we enrolled IDUs into a prospective cohort study involving a baseline questionnaire, comprehensive retrospective and prospective health record linkages. We examined rates of primary care and emergency department utilization, and diagnoses upon arrival in the emergency room. Logistic regression was used to determine factors independently associated with frequent emergency room use. RESULTS: Of the 883 IDUs included in this analysis, 687 (78 per cent) accessed a primary care clinic in the previous year, while 528 (60 per cent) participants accessed the emergency room (ER) during the years 2002 and 2003. Abscesses, cellulitis and other skin infections accounted for the greatest proportion of ER use. Factors independently associated with frequent ER use included: frequent crystal methamphetamine injection (AOR = 2.4, 95 per cent CI: 1.0-5.6); non-fatal overdose (AOR = 2.1, 95 per cent CI: 1.4-3.3); HIV-positive status (AOR = 1.5, 95 per cent CI: 1.1-2.1), having been physically assaulted (AOR = 1.5, 95 per cent CI: 1.1-2.1); and primary care utilization (AOR = 1.5, 95 per cent CI: 1.0-2.1). DISCUSSION: high rates of ER use were observed among IDUs, despite high rates of primary care use among this same population. ER use was due primarily to preventable injection-related complications that are less amenable to primary care interventions, and therefore educational and prevention efforts that encourage and enable sterile injection practices should be promoted.     

Do social factors affect where patients die: an analysis of 10 years of cancer deaths in England.

BACKGROUND: This study investigated whether indices of social deprivation were related to the proportion of cancer patients who died at home. METHODS: Data were derived from death registrations for all cancer deaths 1985-1994 in England. Two indices of deprivation (Underprivileged Area Score (UPA), or Jarman, and Townsend scores) were calculated for each electoral ward; 1991 Census data were used. The scores use combinations of variables, including the percentage in overcrowded homes, the percentage of elderly people living alone, the percentage of one-parent families, etc. A high score indicates more deprivation. The main outcome measures were the proportion (in five and ten year averages) of cancer deaths which occurred at home, calculated for every electoral ward (with populations usually ranging from 5000 to 11,000). Spearman rho was used to test for correlations between the proportion of cancer deaths at home and deprivation score. Electoral wards were categorized by deprivation score into three groups of equal size and analysed over 10 years. Multivariate analysis was used to determine the relative association of different patient based and electoral ward variables with cancer death at home. p < 0.05 (two-tailed) was taken as significant. RESULTS: There were over 1.3 million death registrations from cancer in the 10 years. The proportion who died at home was 0.27, in hospital 0.47, and other setting 0.26. There were wide variations (0.05-0.75) in the proportion of people who died at home in different electoral wards. Small inverse correlations were found between the percentage who died at home and the UPA (-0.35; p < 0.001) and Townsend (-0.26; p < 0.001) scores. The correlations were greatest in North Thames (-0.63, UPA) and smallest in West Midlands (-0.20, UPA). The proportion of home deaths for the different bands of deprivation were: 0.30 (low deprivation), 0.27 (middle deprivation) and 0.24 (high deprivation). Plotting the trends over 10 years suggests no change in this relationship. Multiple regression analysis predicted several ward and patient characteristics and accounted for 30 per cent of the variation. Increased age (patient variable), Jarman score and ethnic minorities (both ward variables) were associated with fewer patients dying at home. Being male and having cancer of the digestive organs were associated with home death. CONCLUSION: There are wide variations in the percentage of cancer deaths at home in different electoral wards. Social factors are inversely correlated with home cancer death, and may explain part of this variation. Home care in deprived areas may be especially difficult to achieve.     

Impact of patients' socioeconomic status on the distance travelled for hospital admission in the English National Health Service

OBJECTIVES: To compare the distances travelled for inpatient treatment in England between electoral wards prior to the introduction of a policy to extend patient choice and to consider the impact of patients' socio-economic status. METHODS: Using Hospital Episode Statistics for 2003-04, the distance from a patient's residence to a National Health Service hospital was calculated for each admission. Distances were summed to electoral ward level to give the distribution of distances travelled at ward level. These were analysed to show the distance travelled for different admission types, ages of patient, rural/urban location, and the socioeconomic deprivation of the population of the ward. RESULTS: There is considerable variation in the distances travelled for hospital admission between electoral wards. Some of this is explained by geographical location: individuals living in more rural areas travel further for elective (median 27.2 versus 15.0 km), emergency (25.3 versus 13.9 km) and maternity (25.0 versus 13.9 km) admissions. But individuals located in highly deprived wards travel less far, and this shorter distance is not explained simply by the closer location of hospitals to these wards. CONCLUSIONS: Before the introduction of more patient choice, there were considerable differences between individuals in the distances they travelled for hospital care. An increase in patient choice may disproportionately benefit people from less deprived areas.     

Trends in primary care consultations for asthma in Switzerland, 1989-2002

BACKGROUND: There is widespread debate about trends in the occurrence of asthma in industrialized countries. This study was conducted to investigate time trends in consultations for asthma in primary care in Switzerland. METHODS: Prospective observational study from 1989 to 2002 within the Swiss Sentinel Surveillance Network; a primary care surveillance system. We used time series analysis and non-parametric smoothing methods to investigate long-term and short-term trends in rates of asthma episodes per 1000 consultations. From 1994 to 2002 we compared rates of first episodes with all subsequent consultations for asthma. RESULTS: Overall consultation rates for asthma per 1000 primary care consultations increased from 1989 to 1994 then stabilized and have declined since 2000. Long-term trends showed a small decline in first consultations for asthma from an average of 0.78 (95% credibility intervals (CI) 0.74-0.81) in 1999 to 0.62 (95% CI 0.55-0.69) per 1000 consultations in 2002. Subsequent consultations for asthma have been declining since at least 1994, from an average of 1.5 (95% CI 1.40-1.61) per 1000 consultations in 1994 to 0.93 (95% CI 0.82-1.04) in 2002. In addition, the ratio of subsequent to first episodes of asthma fell in all age groups. CONCLUSIONS: In Switzerland, primary care consultations for asthma, subsequent to the initial diagnosis, have been declining since 1994. This is more likely to be owing to an increase in the use of home medication than to a shift in care to hospital settings. The incidence of diagnosed asthma might also be decreasing.     

Diabetes prevalence and socioeconomic status: a population based study showing increased prevalence of type 2 diabetes mellitus in deprived areas

OBJECTIVE: To establish the relation between socioeconomic status and the age-sex specific prevalence of type 1 and type 2 diabetes mellitus. The hypothesis was that prevalence of type 2 diabetes would be inversely related to socioeconomic status but there would be no association with the prevalence of type 1 diabetes and socioeconomic status. SETTING: Middlesbrough and East Cleveland, United Kingdom, district population 287,157. PATIENTS: 4313 persons with diabetes identified from primary care and hospital records. RESULTS: The overall age adjusted prevalence was 15.60 per 1000 population. There was a significant trend between the prevalence of type 2 diabetes and quintile of deprivation score in men and women (chi 2 for linear trend, p < 0.001). In men the prevalence in the least deprived quintile was 13.4 per 1000 (95% confidence intervals (95% CI) 11.44, 15.36) compared with 17.22 per 1000 (95% CI 15.51, 18.92) in the most deprived. For women the prevalence was 10.84 per 1000 (95% CI 9.00, 12.69) compared with 15.48 per 1000 (95% CI 13.84, 17.11) in the most deprived. The increased prevalence of diabetes in the most deprived areas was accounted for by increased prevalence of type 2 diabetes in the age band 40-69 years. There was no association between the prevalence of type 1 diabetes and socioeconomic status. CONCLUSION: These data confirm an inverse association between socioeconomic status and the prevalence of type 2 diabetes in the middle years of life. This finding suggests that exposure to factors that are implicated in the causation of diabetes is more common in deprived areas.     

Challenges of monitoring use of secondary care at local level: a study based in London, UK.

STUDY OBJECTIVE: To provide those working at district level with practical guidance on using hospital data linked to small geographic areas to explore patterns of care. DESIGN: Examination of the association between age standardised hospital episode rates for the commonest diagnostic categories and deprivation levels (Carstairs index) of the electoral ward of residence. SETTING: An inner London district, Kensington, Chelsea and Westminster, with a population of approximately 325,000. POPULATION: All finished consultant episodes recorded in NHS hospitals for the district population in the year to April 1994. MAIN RESULTS: Many, but not all, disease categories were associated strongly with deprivation, with high episode rates in the most deprived electoral wards. This is partly due to more of those in deprived areas being admitted to hospital and to them being admitted more often. CONCLUSIONS: A wide range of factors needs to be taken into account in interpreting these data. They include the contribution of the private sector and artifacts of both the numerator and denominator. This paper provides a framework for those working at district level to begin to analyse the association between hospitalisation and deprivation locally. It also identifies some of the issues that must be taken into account when seeking to interpret these data.     

Equity in waiting times for two surgical specialties: a case study at a hospital in the North West of England

BACKGROUND: Reducing inequalities in access to the National Health Service is a key government priority. This study investigates the extent to which equitable access is achieved in one routinely administered hospital waiting list system. METHODS: Using hospital episode statistics for one hospital in the North West of England, a retrospective study of waiting times to surgery was undertaken for two surgical specialties (Orthopaedics and Ophthalmology). Participants were 4306 waiting list patients (elective, first episodes) living within Health Authority boundaries, treated within the two specialties between 1 April 2000 and 31 March 2001. Multiple logistic regression analysis of the relationship between waiting times and age, gender, ethnicity and deprivation status was undertaken. Main outcome measures were length of waiting time between being referred to the waiting list and treatment, and odds ratios for being associated with longer than median waiting times by age, gender, ethnicity and deprivation. RESULTS: For ophthalmology, the median waiting time was 140 days. After adjustment, older people had an odds ratio (OR) of 1.64 (95 per cent confidence interval (CI) 1.42-1.89), patients in deprived areas an OR of 1.29 (95 per cent CI 1.08-1.55) and men an OR of 0.79 (95 per cent CI 0.68-0.92) for having longer than median waiting times. No significant association was found between waiting times and ethnicity. For orthopaedics, the median waiting time was 129 days, and there were no significant differences in waiting times according to age, gender, ethnicity or deprivation. CONCLUSION: Routine waiting list systems are not always delivered equitably. For one specialty, female, older and deprived patients were significantly more likely to experience longer than average waits. Potential explanations and implications for policy-makers are considered.     

Depression,neighborhood deprivation and risk of type 2 diabetes

Neighborhood characteristics have been associated with both depression and diabetes, but to date little attention has been paid to whether the association between depression and diabetes varies across different types of neighborhoods. This prospective study examined the relationship between depression, neighborhood deprivation, and risk of type 2 diabetes among 336,340 adults from a national-representative sample of primary care centers in Sweden (2001–2007). Multi-level logistic regression models were used to assess associations between depression and risk of type 2 diabetes across affluent and deprived neighborhoods. After accounting for demographic, individual-level socioeconomic, and health characteristics, depression was significantly associated with risk of diabetes (odds ratio (OR): 1.10, 95% confidence interval (CI): 1.06–1.14), as was neighborhood deprivation (OR for high vs. low deprivation: 1.66, 95% CI: 1.22–1.34). The interaction term between depression and neighborhood deprivation was non-significant, indicating that the relationship between depression and diabetes risk is similar across levels of neighborhood socioeconomic deprivation.     

Unsung heroes who put their lives at risk? Informal caring, health and neighbourhood attachment

BACKGROUND: Previous studies have highlighted the effects of informal caring on mental health, but evidence for its wider impact remains scant. We explored associations between informal care and a range of health (and health-related) measures. We also considered previously neglected differences between informal care 'at home' and care elsewhere, along with neighbourhood attachment as a possible modifier of the associations we found. METHODS: The study involved a large population survey in two Primary Care Trusts. Data were collected by postal survey of 15,465 adults; subjects were selected from the local General Practice register. 12.7 per cent of respondents identified themselves as carers. Health measures included psychiatric morbidity, bodily pain, self-assessed health, health-related behaviours, obesity, prescribed drugs and high levels of GP consultation. RESULTS: Of nine measures considered, care at home was associated with psychiatric morbidity (OR 1.46, 95 per cent CI 1.25--1.70), bodily pain (OR 1.19, 95 per cent CI 1.02--1.39), and obesity (OR 1.59, 95 per cent CI 1.34--1.89). Care 'away' was associated with smoking (OR 1.26, 95 per cent CI 1.03--1.54), and inversely with both sedentary living (OR 0.70, 95 per cent CI 0.58--0.85) and poor self-assessed health (OR 0.78, 95 per cent CI 0.62--0.99). Health tended to be poorer when carers lacked a sense of neighbourhood attachment. CONCLUSIONS: Informal carers are likely to face serious health challenges besides anxiety and depression. Caring is associated with several aspects of poor health, which are themselves predictors of premature mortality. Proactive and wide-ranging support is required, the more so in neighbourhoods where carers feel alienated. Research and policy should distinguish carers 'at home' from carers 'away'.     

Health needs in a London district.

The hospital admission rate in Inner London is higher than for the country as a whole. This could be because more beds are available or because the local population has special needs. This paper considers admission rates by electoral wards within one Inner London District. The paper shows that the high admission rates are characteristic of electoral wards which exhibit severe social deprivation and that the more affluent wards do not have high hospitalization rates despite the fact that residents of all electoral wards have equal access to hospital. Our conclusion is that the high hospitalization rates in Inner London are at least in part due to social deprivation and that any allocation of health resources needs to make adequate and additional provision for the health needs of communities which are socially deprived.     

Inequalities in provision of systematic care for patients with diabetes

BACKGROUND: GPs are now playing a greater role in the care of people with diabetes; however, the level of performance in primary care is variable. Practices with a recall system and diabetes mini-clinic have been shown to achieve better outcome of care of patients with diabetes. Systematic care also requires effective community-based diabetes services and access to primary care diabetes teams including dieticians, chiropodists, and optometrists and ophthalmologists. OBJECTIVES: The aims of this study were to determine how services for people with diabetes are organized in primary care and whether there are inequalities in systematic care of people with diabetes. METHODS: A piloted postal questionnaire was sent to all 327 general practices in three health authorities in England serving a population of >2 million people. The three health authorities provided practice-based routine data relating to all general practices. RESULTS: A total of 264 (80.7%) practices replied; 236 (89.4%) employed a diabetes recall system and 196 (74.2%) reviewed their patients in a diabetes mini-clinic. Multiple regression showed that having a recall system was associated independently with a GP [odds ratio (OR) 6.2; 95% confidence interval (CI) 2.6-14.9] or a practice nurse (OR 3.5; 1.4-8.7) with an interest in diabetes. Having a diabetes mini-clinic was associated independently with a GP with an interest in diabetes (OR 4.1; 2.1-7.8), a practice nurse having attended a diabetes course (OR 2.8, 1.3-6.2), practices with more partners (OR 1.2 per additional partner; 1.0-1.4) and fundholding practices (OR 2.6; 1.2-5.5). One hundred and sixteen (43.9%) practices had a chiropodist present in the practice, and 90 (34.1%) had a practice-based dietician. A chiropodist and a dietician were significantly more likely to be attached in training practices and in less deprived areas. A practice-based dietician was significantly associated with larger practices. CONCLUSIONS: Providing high quality primary care is essential to meeting the government's agenda of reducing inequalities. This study shows high levels of structured diabetes care which are not related to deprivation. However, practices in more deprived areas still lag behind practices in more affluent areas in terms of access to members of the diabetes team. To improve care of people with diabetes in primary care, deficiencies and inequalities highlighted in our survey must be addressed. The results of this survey will be valuable to primary care groups and organizations responsible for commissioning diabetes services.     

Social deprivation and breast cancer

BACKGROUND: This cross-sectional study was carried out in a population-based setting in Worcestershire to investigate the relationship between social deprivation and other potential prognostic factors. METHODS: A total of 762 female patients diagnosed with primary breast cancer between 1 January 1998 and 31 December 1999 were selected. Breast cancer included all new cases of primary invasive breast cancer and ductal carcinoma in situ. A total of 753 patients were matched by their postcode of residence to enumeration district Townsend score and then divided into three groups based on Townsend quintiles (affluent n = 478; middle n = 157; deprived n = 118). Main outcome measures were relationships between social deprivation and tumour type, stage at presentation, oestrogen receptor status, tumour grade and treatment type. RESULTS: Compared with the most deprived women, affluent women were less likely to present with invasive ductal tumours (70.8 per cent versus 85.9 per cent, chi2 linear trend = 6.757, p = 0.009), tumours of higher grade (36.0 per cent versus 44.7 per cent, chi2 linear trend = 4.201, p = 0.040), and oestrogen receptor negative tumours (22.4 per cent versus 33.3 per cent, chi2 linear trend = 3.501, p = 0.061). There was no significant difference in stage or tumour size at presentation between deprivation groups. More deprived women with invasive tumours of less than 20 mm maximum diameter were significantly more likely to have mastectomies than affluent women (47.8 per cent versus 32.1 per cent, chi2 linear trend = 4.091, p = 0.043). CONCLUSIONS: This study suggests that level of social deprivation is associated with tumour type, grade and oestrogen receptor status. There was also a suggestion that increased level of deprivation was associated with increased risk of potentially unnecessary mastectomies.
