Prospective study of predictors of attendance for breast screening in inner London.

OBJECTIVE--To investigate the predictors of first-round attendance for breast screening in an inner city area. DESIGN--Prospective design in which women were interviewed or completed a postal questionnaire before being sent their invitation for breast screening. Sociodemographic factors, health behaviours, and attitudes, beliefs, and intentions were used as predictors of subsequent attendance. A randomised control group was included to assess the effect of being interviewed on attendance. SETTING--Three neighbouring health districts in inner south east London. PARTICIPANTS--A total of 3291 women aged 50-64 years who were due to be called for breast screening for the first time. The analysis of predictors was based on a subsample of 1301, reflecting a response rate of 75% to interview and 36% to postal questionnaire. MAIN RESULTS--Attendance was 42% overall, and 70% in those who gave an interview or returned a questionnaire. There was little evidence for an interview effect on attendance. The main findings from the analysis of predictors are listed below. (These were necessarily based on those women who responded to interview/questionnaire and so may not be generalisable to the full sample.) (1) Sociodemographic factors: Women in rented accommodation were less likely to go for screening but other indicators of social class and education were not predictive of attendance. Age and other risk factors for breast cancer were unrelated to attendance, as was the distance between home and the screening centre. Married or single women were more likely to attend than divorced, separated, or widowed women, and black women had a higher than average attendance rate; however, neither of these relationships was found in the interview sample. (2) Health behaviours: Attenders were less likely to have had a recent breast screen, more likely to have had a cervical smear, more likely to go to the dentist for check ups, and differed from non-attenders with regard to drinking frequency. Exercise, smoking, diet change, and breast self-examination were unrelated to attendance. (3) Attitudes, beliefs, and intentions: The two best predictors were measures of the perceived importance of regular screening for cervical and breast cancer and intentions to go for breast screening. Also predictive were beliefs about the following: the personal consequences of going for breast screening, the effectiveness of breast screening, the chances of getting breast cancer, and the attitudes of significant others (the womans husband/partner and children). Women who reported a moderate amount of worry about breast cancer were more likely to attend than those at the two extremes. CONCLUSIONS--Attenders and non-attenders differ in two broad areas: the health related behaviours they engage in and the attitudes, beliefs, and intentions they have towards breast cancer and breast screening. The latter are potentially amenable to change, and though different factors may operate among women who do not respond to questionnaires, the findings offer hope that attendance rates can be improved by targeting the relevant attitudes and beliefs. This could be done by changing the invitation letter and its accompanying literature, through national and local publicity campaigns, and by advice given by GPs, practice nurses, and other health professionals. It is essential that such interventions are properly evaluated, preferably in randomised controlled studies.

Does routine screening for breast cancer raise anxiety? Results from a three wave prospective study in England.

OBJECTIVE--To investigate whether mammography raises anxiety in routinely screened women who receive a negative result. DESIGN--Prospective design in which women completed questionnaires at three key points in the breast screening process: at baseline (before being sent their invitation for breast screening), at the screening clinic immediately before or after screening, and at follow up, about nine months after baseline. Information was obtained from non-attenders as well as from attenders. SETTING--Bromley District Health Authority, served by the South East London Breast Screening Service. PARTICIPANTS--Two overlapping samples were used. Sample A comprised 1500 women aged 50-64 who were due to be called for first round screening at a mobile screening unit. Altogether 1021 (68%) returned a usable questionnaire and 795 of these (78%) also provided adequate information at nine month follow up: there were 695 attenders (including 24 women who received false positive results) and 100 non-attenders. Sample B consisted of 868 women who attended the screening unit in a three month period, 732 (84%) of whom provided adequate data. A total of 306 attenders (including 10 who received false positive results) occurred in both samples and provided adequate information on all occasions. The main analyses were based on these 306 women plus the 100 non-attenders. The analysis of retrospective anxiety took advantage of the larger sample size of 695 attenders. MAIN RESULTS--On average, the women were not unduly anxious at any of the three points in the screening process. Among attenders, there was no difference between anxiety levels immediately before and immediately after screening. Anxiety was lowest at the clinic and highest at baseline but the changes were very small in absolute terms. Anxiety did not predict attendance: there were no differences in anxiety levels between attenders and non-attenders at baseline. As expected, women who received false positive results recalled feeling extremely anxious after they had received the referral letter but their retrospective anxiety was also higher than in the negative screenees at earlier stages in the breast screening process. They also reported having experienced more pain and discomfort during the x ray. CONCLUSIONS--Anxiety does not seem to be an important problem in routinely screened women who receive a negative result. This finding is very reassuring in relation to a major criticism of breast screening programmes. Thus, apart from maintaining current procedures such as keeping waiting times to a minimum, there seems to be no need to introduce special anxiety reducing interventions into the national programme. On the other hand, the findings for women who received false positive results suggest that there are aspects of the experience of being recalled for assessment after an abnormal mammogram that warrant further attention. The relationship between contemporaneous and retrospective anxiety should also be studied.

Poor uptake of primary healthcare registration among recent entrants to the UK: a retrospective cohort study.

Objectives Uptake of healthcare among migrants is a complex and controversial topic; there are multiple recognised barriers to accessing primary care. Delays in presentation to healthcare services may result in a greater burden on costly emergency care, as well as increased public health risks. This study aimed to explore some of the factors influencing registration of new entrants with general practitioners (GPs). Design Retrospective cohort study. Setting Port health screening at Heathrow and Gatwick airports, primary care. Participants 252 559 new entrants to the UK, whose entry was documented by the port health tuberculosis screening processes at Heathrow and Gatwick. 191 had insufficient information for record linkage. Primary outcome measure Registration with a GP practice within the UK, as measured through record linkage with the Personal Demographics Service (PDS) database. Results Only 32.5% of 252 368 individuals were linked to the PDS, suggesting low levels of registration in the study population. Women were more likely to register than men, with a RR ratio of 1.44 (95% CI 1.41 to 1.46). Compared with those from Europe, individuals of nationalities from the Americas (0.43 (0.39 to 0.47)) and Africa (0.74 (0.69 to 0.79)) were less likely to register. Similarly, students (0.83 (0.81 to 0.85)), long-stay visitors (0.82 (0.77 to 0.87)) and asylum seekers (0.46 (0.42 to 0.51)) were less likely to register with a GP than other migrant groups. Conclusions Levels of registration with GPs within this selected group of new entrants, as measured through record linkage, are low. Migrant groups with the lowest proportion registered are likely to be those with the highest health needs. The UK would benefit from a targeted approach to identify the migrants least likely to register for healthcare and to promote access among both users and service providers.

The implementation of chlamydia screening: a cross-sectional study in the South East of England

Background Englands National Chlamydia Screening Programme (NCSP) provides opportunistic testing for under 25 year-olds in healthcare and non-healthcare settings. The authors aimed to explore relationships between coverage and positivity in relation to demographic characteristics or setting, in order to inform efficient and sustainable implementation of the NCSP. Methods The authors analysed mapped NCSP testing data from the South East region of England between April 2006 and March 2007 inclusive to population characteristics. Coverage was estimated by sex, demographic characteristics and service characteristics, and variation in positivity by setting and population group. Results Coverage in females was lower in the least deprived areas compared with the most deprived areas (OR 0.48; 95% CI 0.45 to 0.50). Testing rates were lower in 20–24-year-olds compared with 15–19-year-olds (OR 0.69; 95% CI 0.67 to 0.72 for females and OR 0.67; 95% CI 0.64 to 0.71 for males), but positivity was higher in older males. Females were tested most often in healthcare services, which also identified the most positives. The greatest proportions of male tests were in university (27%) and military (19%) settings which only identified a total of 11% and 13% of total male positives respectively. More chlamydia-positive males were identified through healthcare services despite fewer numbers of tests. Conclusions Testing of males focused on institutional settings where there is a low yield of positives, and limited capacity for expansion. By contrast, the testing of females, especially in urban environments, was mainly through established healthcare services. Future strategies should prioritise increasing male testing in healthcare settings.

Rapid estimation of excess mortality: nowcasting during the heatwave alert in England and Wales in June 2011

Background A Heat-Health Watch system has been established in England and Wales since 2004 as part of the national heatwave plan following the 2003 European-wide heatwave. One important element of this plan has been the development of a timely mortality surveillance system. This article reports the findings and timeliness of a daily mortality model used to ‘nowcast’ excess mortality (utilising incomplete surveillance data to estimate the number of deaths in near-real time) during a heatwave alert issued by the Met Office for regions in South and East England on 24 June 2011. Methods Daily death registrations were corrected for reporting delays with historical data supplied by the General Registry Office. These corrected counts were compared with expected counts from an age-specific linear regression model to ascertain if any excess had occurred during the heatwave. Results Excess mortality of 367 deaths was detected across England and Wales in ≥85-year-olds on 26 and 27 June 2011, coinciding with the period of elevated temperature. This excess was localised to the east of England and London. It was detected 3 days after the heatwave. Conclusion A daily mortality model was sensitive and timely enough to rapidly detect a small excess, both, at national and regional levels. This tool will be useful when future events of public health significance occur.

Lessons of a hip failure: Registers of joint replacement operations should be set up

Editor—Fickleness characterises the fashion industry. The fact that the introduction and use of hip prostheses in the United Kingdom should also be characterised by such whimsy is scandalous.1 The failure of the 3M Capital hip system and the difficulties in tracing and reviewing patients as a result bear witness to this.2,3 While we agree with the points made by Muirhead-Allwood in her editorial, she does not take the next logical step of requiring the establishment of a national hip prosthesis register. On the introduction of new prostheses and monitoring of outcomes, a register would provide a nationally coherent database recording preoperative, perioperative, and postoperative follow up information. It has been estimated that around 62 different replacement hip joints are available in Britain, manufactured by 19 different companies. Part of the problem in evaluating their effectiveness is the lack of high quality, prospective, comparative studies.4 A national register would provide the basis for scientifically well designed, statistically robust studies. Registers in Sweden and Norway collect a lot of relevant patient data and use these to allow adjustments for the effects of case mix when comparisons are made. We were provoked by the failure of the 3M Capital hip into ascertaining the national view of the need to establish a register and sent a UK-wide Epinet message to all directors of public health. The replies showed that several databases, audits, and research projects exist, but they are uncoordinated, geographically restricted, and, for some, strictly time limited. The overwhelming response was for the establishment of a national database to unite this research. In the light of the importance that the government attaches to clinical effectiveness and the establishment of clinical governance in trusts,5 we hope that this call for a national register is heard and acted on.

Local authorities should be responsible for public health

Concern about the health reforms has focused on the NHS.1 We have concerns about responsibility for public health. If implemented, the bill will remove statutory responsibility to protect the public’s health from any local organisation. The NHS Act 2006 makes primary care trusts (PCTs) responsible for protecting and improving population health. This underpins the current public health system. Although partnership working is crucial, the “buck …
