Missing, mediocre, or merely obsolete? An evaluation of UK data sources for coronary heart disease.

STUDY OBJECTIVE: Coronary heart disease (CHD) is the commonest cause of death in the UK. However, there is no single comprehensive source of information to support CHD prevention and treatment strategies. Therefore this study evaluated the availability and quality of UK CHD data sources since 1981. DESIGN: Data sources for England and Wales were identified and appraised on: (1) CHD patient numbers (myocardial infarction, angina, hypertension, and heart failure); (2) uptake of medical and surgical CHD treatments, and (3) population trends in major cardiovascular risk factors. SETTING: England and Wales (population 53 million). MAIN RESULTS: Population and mortality data were easily accessible from Office for National Statistics and British Heart Foundation Annual CHD Statistics; population based risk factor data came principally from the British Regional Heart Study, the General Household Survey, and the Health Survey for England. They were limited for 1981, but more extensive by 2000. Hospital admissions information since 1998 was available online from HES; but trend data and details of interventions were scant. Limited primary care data on consultation rates, prescribing, and treatment uptake were available from published audits and studies. CONCLUSIONS: Information on CHD in the UK is fragmented, patchy, and mixed in quality. Data for women, the elderly populatiom, and ethnic minorities were particularly scarce, exacerbating inequalities. Future CHD disease monitoring and evaluation will require comprehensive and accurate population based information on trends in patient numbers, treatment uptake, and risk factors.

Lessons from the implementation of a home telecare service.

We conducted a qualitative evaluation of the introduction of a telenursing service. The service used an analogue videophone linked with a physiological monitoring device, which allowed the transmission of data between the patient's home and the hospital. A researcher kept a detailed diary of day-to-day activity for the first year of the project. Computer software for qualitative data analysis was used to code the text and the analysis followed the principles of constant comparison. The diary entries documented how the commercially available equipment was adapted to suit the organization and content of the nurses' work. The nurses made a number of suggestions to improve the user-friendliness of the equipment. The technology, the existing home care service (the comparison arm of the study) and the randomized controlled trial itself all underwent continuous change. The traditional randomized control design of trial has limitations in this situation, and there is a need for more realistic trial designs.

Trends in case-fatality in 22968 patients admitted for the first time with atrial fibrillation in Scotland, 1986-1995.

BACKGROUND: Although atrial fibrillation (AF) is an important cause of cardiovascular morbidity and mortality there is a paucity of data describing hospitalisation rates and case-fatality associated with this common arrhythmia. This study examines recent trends in first-ever hospitalisations for AF in Scotland. METHODS: Using the linked Scottish Morbidity Record Scheme, we identified all 22968 patients admitted to Scottish hospitals for the first time with a principal diagnosis of AF between 1986 and 1995. For each calendar year we calculated short (30-day) and medium (31 day to 2 years) case-fatality rates. Adjusting for each patient's age, sex, deprivation status, concurrent diagnoses and prior hospitalisation status, we examined whether case-fatality rates had significantly improved during this 10-year period. RESULTS: Between 1986 and 1995 the number of men hospitalised for the first time with AF increased by 926 (125%) to 1730 per annum and the number of women and by 875 (105%) to 1712 (both P<0.001). Hospitalisation rates increased from 0.31 to 0.70/1000 men and from 0.32 to 0.65/1000 women (both P<0.001). By the end of this period the proportion of men had increased from 48 to 50%. In both sexes, the median age of patients rose--in men from 66 to 68 years and in women from 74 to 75 years (both P<0.01). Despite the increasing age of patients and greater comorbidity, short-term (30-day) case-fatality declined from 4.0 to 3.1% in men (P<0.001) and 4.1 to 3.8% (P<0.01) in women. Similarly, medium-term (31-day to 2-year) case-fatality fell from 25 to 22% in men and 27 to 25% (both P<0.001) in women. Adjusting for the age, sex, extent of deprivation, secondary diagnoses and prior hospitalisation of hospitalised patients, we found that the risk of short-term case-fatality in the 1995 male and female cohort significantly declined by 21% (P<0.05) and 24% (P<0.05), respectively, in comparison to the 1986 cohort. The adjusted risk of case-fatality in the medium term also declined significantly in men by 30% (P<0.05) over this period and by 20% (P<0.05) in women relative to 1986. CONCLUSION: The number of first-ever hospitalisations for AF has increased twofold during the 10-year period 1986-1995. Although the age of patients has progressively increased during this period, short and medium case-fatality rates have declined, especially in men. This may partly reflect better treatment of AF. However, changing admission thresholds and other factors could also have led to an apparent improvement in prognosis. Nevertheless, medium-term case fatality remains substantial after a first ever admission to hospital with AF.

Substantial between-hospital variation in outcome following first emergency admission for heart failure.

BACKGROUND: Following hospitalization with a range of cardiovascular disorders, substantial variation has been noted in clinical outcome, both between and within countries. OBJECTIVES: To examine the variation, between hospitals, in the clinical outcomes of death and readmission following hospitalization with heart failure in Scotland. Setting All 29 acute hospitals in Scotland with more than 200 beds. PATIENTS: All 31 452 patients discharged from these hospitals between January 1990 and December 1995 with a first-ever, primary, diagnosis at discharge/death of heart failure. ANALYSIS: An analysis of the Scottish database of discharge summaries linking index admissions with subsequent admissions and deaths. Death rates and readmission rates were adjusted for baseline age, co-morbidity and socio-economic status and were calculated at different time periods (inpatient, 30 days, 1 year). Rates were calculated separately for large teaching hospitals (n=6, category A), large general hospitals with specialist units (n=8, category B) and medium sized general hospitals with limited specialist units (n=15 category C). RESULTS: A total of 31 452 patients were discharged between 1990-1995 - 10 219 (33%), 9735 (31%) and 11 498 (37%) to category A, B and C hospitals, respectively. The national, average, inpatient case fatality rate was 15.3%, ranging, in individual hospitals, from the lowest rate of 8.5% to the highest rate of 23.4%. The average 1 year case fatality rate was 42.4%, ranging between 35.3% and 50.8%. A similar two- to threefold variation was found in hospital readmission rates - thus the average 30 day readmission rate was 5.3% (lowest 3.3%, highest 7.3%). This variation, in both case-fatality and readmission rates, was apparent within all three groups of hospitals and persisted after adjustment for the baseline factors outlined above. CONCLUSIONS: A patient admitted to one Scottish hospital with heart failure may be two to three times more likely to die or be readmitted, both in the short and longer term, compared to a patient admitted to another hospital. Although we may not have accounted for some sources of variation, it is both surprising and disturbing that large, statistically significant, differences in adjusted death and readmission rates can apparently exist for such an important condition in a relatively small country with generally homogenous health care provision. Further, detailed investigation of this apparent variation is required.

A randomized controlled trial of home telecare.

We have established a randomized controlled trial of home telecare. The intervention aims to address a growing problem in the National Health Service (NHS), that is, high admission rates of patients with exacerbations of chronic obstructive pulmonary disease (COPD). Equipment procurement for the trial has been difficult, as no single supplier was able to meet the project s full requirements. The fact that the service is provided by existing clinical NHS staff has advantages when considering the generalizability of the results within the NHS. However, there are also disadvantages, since existing staff have little research experience. Considerable time has been required to help staff familiarize themselves with the equipment and become comfortable with its use. This has posed a barrier to the implementation of the service.

Age, sex, and social trends in out-of-hospital cardiac deaths in Scotland 1986-95: a retrospective cohort study.

BACKGROUND: Most deaths from coronary heart disease occur out of hospital. Hospital patients face social, age, and sex inequalities. Our aim was to examine inequalities and trends in out-of-hospital cardiac deaths. METHODS: We used the Scottish record linked database to identify all deaths from acute myocardial infarction that occurred in Scotland (population 5.1 million), in 1986-95. We have compared population-based death rates for men and women across age and social groups. FINDINGS: Between 1986 and 1995, 83365 people died from acute myocardial infarction, out of hospital and without previous hospital admission (44655 men, 38710 women); and 117749 were admitted with a first acute myocardial infarction, of whom 37020 died within 1 year. Thus, out-of-hospital deaths accounted for 69.2% (95% CI 69.0-69.5) of all 120385 deaths. Out-of-hospital deaths, measured as a proportion of all acute myocardial infarction events (deaths plus first hospital admissions), increased with age, from 20.1% (19.2-21.0) in people younger than 55 years, to 62.1% (61.3-62.9) in those older than 85 years. Population-based out-of-hospital mortality rates fell by a third in men and by a quarter in women. Mean yearly falls were larger in people aged 55-64 years (5.6% per year in men, 3.7% in women), than in those older than 85 years (2.5% in men and women). Mortality rates were substantially higher in deprived socioeconomic groups than in affluent groups, especially in people younger than 65 years. INTERPRETATION: These inequalities in age, sex, and socioeconomic class should be actively addressed by prevention strategies for coronary heart disease.

Gender and survival: a population-based study of 201,114 men and women following a first acute myocardial infarction.

OBJECTIVES: We tested the hypotheses that the effect of gender on short-term case fatality following a first admission for acute myocardial infarction (AMI) varies with age, and that this effect is offset by differences in the proportion of men and women who survive to reach hospital. BACKGROUND: Evidence is conflicting regarding the effect of gender on prognosis after AMI. METHODS: All 201,114 first AMIs between 1986 and 1995 were studied. Both 30-day and 1-year case fatality were analyzed for the 117,749 patients hospitalized and for all first AMIs, including deaths before hospitalization. The effect of gender and its interaction with age on survival was examined using multivariate modeling. RESULTS: Gender-based differences in survival varied according to age in hospitalized patients, with younger women having higher 30-day case fatality than men (e.g., <55 years, women 6.5% vs. 4.8% men, p < 0.0001). When deaths from first AMI before hospitalization were included in 30-day case fatality, women were less likely to die (adjusted odds ratio 0.9, confidence interval 0.89 to 0.93). Gender was not an independent predictor of one-year survival (p = 0.16). CONCLUSIONS: Female gender increases the probability of surviving to reach hospital, and this outweighs the excess risk of death occurring in younger women following hospitalization. Overall, men have a higher 30-day case fatality than women. Women do not fare worse than men after AMI when age and other factors are taken into account. However, men are more likely to die before hospitalization.

More 'malignant' than cancer? Five-year survival following a first admission for heart failure.

BACKGROUND: The prognostic impact of heart failure relative to that of 'high-profile' disease states such as cancer, within the whole population, is unknown. METHODS: All patients with a first admission to any Scottish hospital in 1991 for heart failure, myocardial infarction or the four most common types of cancer specific to men and women were identified. Five-year survival rates and associated loss of expected life-years were then compared. RESULTS: In 1991, 16224 men had an initial hospitalisation for heart failure (n=3241), myocardial infarction (n=6932) or cancer of the lung, large bowel, prostate or bladder (n=6051). Similarly, 14842 women were admitted for heart failure (n=3606), myocardial infarction (n=4916), or cancer of the breast, lung, large bowel or ovary (n=6320). With the exception of lung cancer, heart failure was associated with the poorest 5-year survival rate (approximately 25% for both sexes). On an adjusted basis, heart failure was associated with worse long-term survival than bowel cancer in men (adjusted odds ratio, 0.89; 95% CI, 0.82-0.97; P<0.01) and breast cancer in women (odds ratio, 0.59; 95% CI, 0.55-0.64; P<0.001). The overall population rate of expected life-years lost due to heart failure in men was 6.7 years/1000 and for women 5.1 years/1000. CONCLUSION: With the notable exception of lung cancer, heart failure is as 'malignant' as many common types of cancer and is associated with a comparable number of expected life-years lost.

Poles apart, but are they the same? A comparative study of Australian and Scottish patients with chronic heart failure.

This paper reports on an international comparison of the characteristics, treatment and health outcomes of chronic heart failure (CHF) patients discharged from acute hospital care in Australia and Scotland. The baseline characteristics and treatment of 200 CHF patients recruited to a randomised study of a non-pharmacological intervention in Australia and 157 CHF patients concurrently recruited to a similar study in Scotland were compared. Subsequent health outcomes (including survival and readmission) within 3 months of discharge in those patients who received usual post-discharge care in Australia (n=100) and Scotland (n=75) were also compared. Individuals in both countries were predominantly old and frail with significant comorbidity likely to complicate treatment. Similar proportions of Australian and Scottish patients were prescribed either a 'high' (20 vs. 18%) or medium (64 vs. 66%) dose of an angiotensin-converting enzyme inhibitor. Proportionately more Australian patients were prescribed a long-acting nitrate, digoxin and/or a beta-blocker. At 3 months post-discharge, 57 of the 100 (57%: 95% CI 47--67%) Australian and 37 of the 75 (49%: 95% CI 38--61%) Scottish patients assigned to 'usual care' remained event-free (NS). Similarly, 15 vs. 12% required > or =2 unplanned readmission (NS) and 16 vs. 19% of Australian and Scottish patients, respectively, died (NS). Australian and Scottish patients accumulated a median of 0.6 vs. 0.9 days, respectively, of hospitalisation/patient/month (NS). On multivariate analysis (including country of origin), unplanned readmission or death was independently correlated with severe renal impairment (adjusted odds ratio 4.4, P<0.05), a previous hospitalisation for CHF (2.3, P<0.05), longer index hospitalisation (2.7 for >10 days, P<0.05) and greater comorbidity (1.3 for each incremental unit of the Charlson Index, P=0.05). Health outcomes among predominantly old and frail CHF patients appear to be independent of the health-care system in which the patient is managed and more likely to be dependent on the syndrome itself.

Trends in hospitalization for heart failure in Scotland, 1990-1996. An epidemic that has reached its peak?

AIMS: Studies in the 1980s and early 1990s showed striking increases in hospitalization rates for heart failure. This report describes contemporary trends in hospitalization for heart failure. METHODS: Scotland (population of 5.1 million) has a well described system for recording details of all hospitalizations. All hospital discharges (and deaths) can be linked to each patient. We examined the period 1990-1996 (158 989 hospitalizations with a principal or secondary diagnosis of heart failure). RESULTS: Compared to 1990, the number of hospitalizations with a principal diagnosis of heart failure increased in men (by 16%) and women (by 12%), although the highest numbers were recorded in 1993 in women (21%) and in 1994 in men (24%). Similar trends were seen for the number of patients hospitalized overall and those having a 'first ever' hospitalization. Hospitalizations with a secondary diagnosis of heart failure increased much more strikingly (by 110% and 60% in men and women, respectively). Re-hospitalization became more common, increasing by 53% and representing 23% of all hospitalizations in 1996. Median length of stay fell (from 9 to 8 days in men and 13 to 10 days in women with a principal diagnosis of heart failure), resulting in 100 877 fewer inpatient days. Heart failure (principal diagnosis) still, however, accounted for 4.2% of all inpatient medicine/geriatric bed-days in 1996. Although inpatient case fatality fell slightly, the total number of deaths due to heart failure (principal diagnosis) increased slightly. CONCLUSIONS: Heart failure continues to be a common cause of hospitalization. The previously reported 'epidemic' of increasing rates of hospitalization for heart failure in Scotland and elsewhere between 1980 and 1990, however, seems to have peaked (in about 1993/4).

Trends in hospital activity, morbidity and case fatality related to atrial fibrillation in Scotland, 1986--1996.

AIMS: Atrial fibrillation is a common and important cause of cardiovascular morbidity and mortality that may become more prevalent due to an ageing population and more prolonged exposure to predisposing cardiovascular disease states. This study examines recent trends in hospitalizations related to atrial fibrillation in Scotland. METHODS AND RESULTS: Scotland (population 5.1 million) has a well described system for recording hospitalization data. All hospital discharges (and death) can be linked for each individual patient. We examined the period 1986--1996, during which time a total of 103,085 hospitalizations with a principal or secondary diagnosis of atrial fibrillation were recorded. The number of hospitalizations with a principal diagnosis of atrial fibrillation increased threefold from 1869 in 1986 to 5757 in 1996; the number with a secondary diagnosis rose from 3577 to 11,522. Similar increases were seen in the number of patients hospitalized, in those having a 'first-ever' hospitalization and in population hospitalization rates overall. The average age of patients rose, in men from 63.8 (SD 13.2) to 65.0 (13.2) years and in women from 72.2 (12.2) to 73.2 (11.4) years. The proportion of those aged >75 years rose from 33% to 35% in men and from 56% to 60% in women. Average length of stay and case fatality fell during this period, but, because of the overall increase in hospitalizations, atrial fibrillation contributed to a growing proportion of cardiovascular-related bed-days utilized (from 18% to 37% with atrial fibrillation coded in any diagnostic position). CONCLUSION: The number of hospitalizations for atrial fibrillation has increased dramatically (two- to threefold) in recent years. These findings may be due to a real increase in atrial fibrillation prevalence, changing medical practice (e.g. coding or admission thresholds) or both. Consequently, the public health burden of atrial fibrillation is enormous. Moreover, the observed increase in atrial fibrillation-related hospital activity shows no sign of abating.
