General practice size determines participation in optional activities: cross-sectional analysis of a national primary care system

Background: There is widespread, unexplained variation in activity and outcome between general practices. <BR/> Aim: To explore the relationship between practice size and participation in optional activities, including the Quality and Outcomes Framework (QOF). <BR/> Design of study: Cross-sectional analyses of routinely available data on practice characteristics, QOF performance and optional activities including undergraduate teaching, postgraduate training, research, enhanced clinical data collection and service development. <BR/> Setting: All 1031 general practices were located in mainland Scotland. <BR/> Results: The most popular optional activity was undergraduate medical teaching, which involved 41% of all general practices. About a third of practices took part in postgraduate general practitioner training (29%), research (33%), enhanced clinical data collection through the Scottish Programme for Improving Clinical Effectiveness (31%) and the activities of the Scottish Primary Care Collaborative (33%). The most important driver of the number of activities undertaken by a practice is size with single handed, small and medium sized practices all undertaking a significantly lower number of activities than larger practices (P < 0.001). Deprivation had no overall effect, but was associated with lower rates of participation in postgraduate training. The average number of points achieved in the QOF ranged from 961 by the 18% of practices taking part in no optional activities, to 973 by 29% of practices taking part in one activity, 984 by 25% of practices taking part in two activities and 985 in 28% of practices taking part in three or more activities. Single handed practices in urban areas taking part in three or more additional activities had similar QOF point totals to larger practices taking part in three or more activities, and achieved 44 more QOF points than urban single-handed practices taking part in less than two additional activities. <BR/> Conclusions: Practice size is strongly related to participation in optional activities. There is a small but significant relationship between the practice size and number of QOF points achieved by practices taking part in less than two additional activities. Participation in optional activities is a possible indicator of cultural and organisational factors within practices, which constrain the volume and quality of services, which they are able to provide

Living and health conditions of Palestinian refugees in an unofficial camp in the Lebanon: a cross-sectional survey

<b>Objective</b> To determine the living conditions and self-reported health of Palestinian refugees living in an unofficial camp in Lebanon.<p></p> <b>Design</b> Cross-sectional survey.<p></p> <b>Setting</b> Gaza displacement centre, Beirut, Lebanon.<p></p> <b>Participants</b> 97 Households and 437 residents.<p></p> <b>Main outcome measures</b> Household characteristics, including the number of rooms per household; access to outside air; the presence of mould and dampness. Resident characteristics, including age; educational attainment; and chronic conditions.<p></p> <b>Results</b> Half of the households surveyed had only one room; 44% had three or more people per room; 11% had no external ventilation; 49% had no heating; 54% had mould and dampness. The use of wood or charcoal for heating was associated with an increase in mould and dampness (p = 0.015). 135 Members of the population (31%) were aged under 15 years; 130 (30%) had a chronic condition. Logistic regression results showed that overcrowding (odds ratio (OR) 3.26) and a member of the household living in Gaza buildings for more than 15 years (OR 0.48) were significantly associated with children under 15 years. Age over 45 years (OR 5.32), a member of the household in full-time employment (OR 0.58) and a member of the household living in Gaza buildings for more than 15 years (OR 1.71) were significantly associated with chronic disease.<p></p> <b>Conclusion</b> This study demonstrates the poor conditions under which Palestinian refugees in unofficial camps live, resembling the slum housing of the United Kingdom in the last century. In the absence of routine data collection, research may be the only way to obtain such data for future public and environmental health planning

Building on Julian Tudor Hart's example of anticipatory care

The prevention and delay of chronic disease is an increasing priority in all advanced health-care systems, but sustainable, effective and equitable approaches remain elusive. In a famous pioneering example in the UK, Julian Tudor Hart combined reactive and anticipatory care within routine consultations in primary medical care, while applying a population approach to delivery and audit. This approach combined the structural advantages of UK general practice, including universal coverage and the absence of user fees, with his long-term commitment to individual patients, and was associated with a 28% reduction in premature mortality over a 25-year period. The more recent, and comprehensively evaluated Scottish National Health Service demonstration project, ‘Have a Heart Paisley’, took a different approach to cardiovascular prevention and health improvement, using population screening for ascertainment, health coaches and referral to specific health improvement programmes for diet, smoking and exercise. We draw from both examples to construct a conceptual framework for anticipatory care, based on active ingredients, programme pathways and whole system approaches. While the strengths of a family practice approach are coverage, continuity, co-ordination and longterm relationships, the larger health improvement programme offered additional resources and expertise. As theory and evidence accrue, the challenge is to combine the strengths of primary medical care and health improvement, in integrated, sustainable systems of anticipatory care, addressing the heterogeneity of individual needs and solutions, while achieving high levels of coverage, continuity, co-ordination and outcome

After 50 years and 200 papers, what can the Midspan cohort studies tell us about our mortality?

Objective: To distil the main findings from published papers on mortality in three cohorts involving over 27,000 adults, recruited in Scotland between 1965 and 1976 and followed up ever since. Method: We read and summarized 48 peer-reviewed papers about all-cause and cause-specific mortality in these cohorts, published between 1978 and 2013. Results: Mortality rates were substantially higher among cigarette smokers in all social classes and both genders. Exposure to second-hand smoke was also damaging. Exposure to higher levels of black smoke pollution was associated with higher mortality. After smoking, diminished lung function was the risk factor most strongly related to higher mortality, even among never-smokers. On average, female mortality rates were much lower than male but the same risk factors were predictors of mortality. Mortality rates were highest among men whose paternal, own first and most recent jobs were manual. Specific causes of death were associated with different life stages. Upward and downward social mobility conferred intermediate mortality rates. Low childhood cognitive ability was strongly associated with low social class in adulthood and higher mortality before age 65 years. There was no evidence that daily stress contributed to higher mortality among people in lower social positions. Men in manual occupations with fathers in manual occupations, who smoked and drank >14 units of alcohol a week had cardiovascular disease mortality rates 4.5 times higher than non-manual men with non-manual fathers, who neither smoked nor drank >14 units. Men who were obese and drank >14 units of alcohol per day had a mortality rate due to liver disease 19 times that of normal or underweight non-drinkers. Among women who never smoked, mortality rates were highest in severely obese women in the lowest occupational classes. Conclusion: These studies highlight the cumulative effect of adverse exposures throughout life, the complex interplay between social circumstances, culture and individual capabilities, and the damaging effects of smoking, air pollution, alcohol and obesity

Effect of tobacco smoking on survival of men and women by social position: a 28 year cohort study

<b>Objective:</b> To assess the impact of tobacco smoking on the survival of men and women in different social positions. <b>Design:</b> A cohort observational study. <b>Setting:</b> Renfrew and Paisley, two towns in west central Scotland. <b>Participants:</b> 8353 women and 7049 men aged 45-64 years recruited in 1972-6 (almost 80% of the population in this age group). The cohort was divided into 24 groups by sex (male, female), smoking status (current, former, or never smokers), and social class (classes I + II, III non-manual, III manual, and IV + V) or deprivation category of place of residence. <b>Main outcome measure:</b> Relative mortality (adjusted for age and other risk factors) in the different groups; Kaplan-Meier survival curves and survival rates at 28 years. <b>Results:</b> Of those with complete data, 4387/7988 women and 4891/6967 men died over the 28 years. Compared with women in social classes I + II who had never smoked (the group with lowest mortality), the adjusted relative mortality of smoking groups ranged from 1.7 (95% confidence interval 1.3 to 2.3) to 4.2 (3.3 to 5.5). Former smokers’ mortalities were closer to those of never smokers than those of smokers. By social class (highest first), age adjusted survival rates after 28 years were 65%, 57%, 53%, and 56% for female never smokers; 41%, 42%, 33%, and 35% for female current smokers; 53%, 47%, 38%, and 36% for male never smokers; and 24%, 24%, 19%, and 18% for male current smokers. Analysis by deprivation category gave similar results. <b>Conclusions:</b> Among both women and men, never smokers had much better survival rates than smokers in all social positions. Smoking itself was a greater source of health inequality than social position and nullified women’s survival advantage over men. This suggests the scope for reducing health inequalities related to social position in this and similar populations is limited unless many smokers in lower social positions stop smoking

Different effects of oral and transdermal hormone replacement therapies on Factor IX, APC resistance, t-PA, PAI and C- reactive protein - a cross-sectional population survey

The effects of hormone replacement therapy (HRT) on thrombosis risk, thrombotic variables, and the inflammatory marker C- reactive protein (CRP) may vary by route of administration (oral versus transdermal). We studied the relationships of 14 thrombotic variables (previously related to cardiovascular risk) and CRP to menopausal status and to use of HRT subtypes in a cross-sectional study of 975 women aged 40-59 years. Our study confirmed previously-reported associations between thrombotic variables and menopausal status. Oral HRT use was associated with increased plasma levels of Factor IX, activated protein C (APC) resistance, and CRP; and with decreased levels of tissue plasminogen activator (t-PA) antigen and plasminogen activator inhibitor (PAI) activity. Factor VII levels were higher in women taking unopposed oral oestrogen HRT. The foregoing associations were not observed in users of transdermal HRT; hence they may be consequences of the "first- pass" effect of oral oestrogens on hepatic protein synthesis. We conclude that different effects of oral and transdermal HRT on thrombotic and inflammatory variables may be relevant to their relative thrombotic risk; and suggest that this hypothesis should be tested in prospective, randomised studies

Associations of height, leg length, and lung function with cardiovascular risk factors in the Midspan Family Study

<b>Background</b>: Taller people and those with better lung function are at reduced risk of coronary heart disease (CHD). Biological mechanisms for these associations are not well understood, but both measures may be markers for early life exposures. Some studies have shown that leg length, an indicator of pre-pubertal nutritional status, is the component of height most strongly associated with CHD risk. Other studies show that height-CHD associations are greatly attenuated when lung function is controlled for. This study examines (1) the association of height and the components of height (leg length and trunk length) with CHD risk factors and (2) the relative strength of the association of height and forced expiratory volume in one second (FEV1) with risk factors for CHD. <b>Subjects and methods</b>: Cross sectional analysis of data collected at detailed cardiovascular screening examinations of 1040 men and 1298 women aged 30–59 whose parents were screened in 1972–76. Subjects come from 1477 families and are members of the Midspan Family Study. <b>Setting</b>: The towns of Renfrew and Paisley in the West of Scotland. <b>Results</b>: Taller subjects and those with better lung function had more favourable cardiovascular risk factor profiles, associations were strongest in relation to FEV1. Higher FEV1 was associated with lower blood pressure, cholesterol, glucose, fibrinogen, white blood cell count, and body mass index. Similar, but generally weaker, associations were seen with height. These associations were not attenuated in models controlling for parental height. Longer leg length, but not trunk length, was associated with lower systolic and diastolic blood pressure. Longer leg length was also associated with more favourable levels of cholesterol and body mass index than trunk length. <b>Conclusions</b>:These findings provide indirect evidence that measures of lung development and pre-pubertal growth act as biomarkers for childhood exposures that may modify an individual's risk of developing CHD. Genetic influences do not seem to underlie height-CHD associations

Double trouble: the impact of multimorbidity and deprivation on preference-weighted health related quality of life - a cross sectional analysis of the Scottish Health Survey

<b>Objective</b> To investigate the association between multimorbidity and Preference_Weighted Health Related Quality of Life (PW_HRQoL), a score that combines physical and mental functioning, and how this varies by socioeconomic deprivation and age.<p></p> <b>Design</b> The Scottish Health Survey (SHeS) is a cross-sectional representative survey of the general population which included the SF-12, a survey of HRQoL, for individuals 20 years and over.<p></p> <b>Methods</b> For 7,054 participants we generated PW_HRQoL scores by running SF-12 responses through the SF-6D algorithm. The resulting scores ranged from 0.29 (worst health) to 1 (perfect health). Using ordinary least squares, we first investigated associations between scores and increasing counts of longstanding conditions, and then repeated for multimorbidity (2+ conditions). Estimates were made for the general population and quintiles of socioeconomic deprivation. For multimorbidity, the analyses were repeated stratifying the population by age group (20--44, 45--64, 65+).<p></p> <b>Results</b> 45% of participants reported a longstanding condition and 18% reported multimorbidity. The presence of 1, 2, or 3+ longstanding conditions were associated with average reductions in PW_HRQoL scores of 0.081, 0.151 and 0.212 respectively. Reduction in scores associated with multimorbidity was 33% greater in the most deprived quintile compared to the least deprived quintile, with the biggest difference (80%) in the 20--44 age groups. There were no significant gender differences.<p></p> <b>Conclusions</b> PW_HRQoL decreases markedly with multimorbidity, and is exacerbated by higher deprivation and younger age. There is a need to prioritise interventions to improve the HRQoL for (especially younger) adults with multimorbidity in deprived areas

Intergenerational 20 year trends in the prevalence of asthma and hay fever in adults: the Midspan family study surveys of parents and offspring

<b>Objective</b>: To estimate trends between 1972-6 and 1996 in the prevalences of asthma and hay fever in adults. Design: Two epidemiological surveys 20 years apart. Identical questions were asked about asthma, hay fever, and respiratory symptoms at each survey. Setting: Renfrew and Paisley, two towns in the west of Scotland. <b>Subjects</b>: 1477 married couples aged 45-64 participated in a general population survey in 1972-6; and 2338 offspring aged 30-59 participated in a 1996 survey. Prevalences were compared in 1708 parents and 1124 offspring aged 45-54. <b>Main outcome measures</b>: Prevalences of asthma, hay fever, and respiratory symptoms. Results: In never smokers, age and sex standardised prevalences of asthma and hay fever were 3.0% and 5.8% respectively in 1972-6, and 8.2% and 19.9% in 1996. In ever smokers, the corresponding values were 1.6% and 5.4% in 1972-6 and 5.3% and 15.5% in 1996. In both generations, the prevalence of asthma was higher in those who reported hay fever (atopic asthma). In never smokers, reports of wheeze not labelled as asthma were about 10 times more common in 1972-6 than in 1996. With a broader definition of asthma (asthma and/or wheeze), to minimise diagnostic bias, the overall prevalence of asthma changed little. However, diagnostic bias mainly affected non-atopic asthma. Atopic asthma increased more than twofold (prevalence ratio 2.52 (95% confidence interval 1.01 to 6.28)) whereas the prevalence of non-atopic asthma did not change (1.00 (0.53 to 1.90)). <b>Conclusion</b>: The prevalence of asthma in adults has increased more than twofold in 20 years, largely in association with trends in atopy, as measured indirectly by the prevalence of hay fever. No evidence was found for an increase in diagnostic awareness being responsible for the trend in atopic asthma, but increased awareness may account for trends in non-atopic asthma
