Stroke presentation and hospital management: comparison of neighboring healthcare systems with differing health policies.

BACKGROUND AND PURPOSE: Acute stroke care is shaped by healthcare policies. Differing policies in similar populations allow for assessment of policy impact on health and healthcare outcomes. The purpose of this study was to compare stroke presentation and hospital care in two adjacent healthcare systems with differing healthcare policies. METHODS: Interviews and chart review of consecutive acute stroke admissions in Northern Ireland (n=103) and the Republic of Ireland (n=100). RESULTS: Marked regional contrasts were evident for key aspects of hospital care. Northern Ireland performed significantly better on 15 of 16 quality of care (Sentinel Audit) items. Delivery on standards was significantly better in Northern Ireland for early assessment (Northern Ireland 72%; Republic of Ireland 54%, P<0.01), multidisciplinary review (Northern Ireland 69%; Republic of Ireland 31%, P<0.001), medications review (Northern Ireland 54%; Republic of Ireland 19%, P<0.001), and for discharge-rehabilitation planning (Northern Ireland 83%; Republic of Ireland 8%, P<0.001). Preadmission prescription of advised cardiovascular medications was similar between regions for antihypertensives and anticoagulants but significantly higher in Northern Ireland for antiplatelets (Northern Ireland 65%; Republic of Ireland 38%, P=0.001) and lipid-regulating medication (Northern Ireland 44%; Republic of Ireland 26%; P=0.006). Prescribing levels increased in both regions and all medication categories by discharge but with significantly lower levels in Northern Ireland for antihypertensives (Northern Ireland 60%; Republic of Ireland 75%, P=0.025). Northern Ireland patients were more functionally dependent (mean Barthel Index 10.5 versus 12.7 [Republic of Ireland], P=0.013) and less aphasic (mean Frenchay Aphasia Screening Test 17.8 versus 16.8 [Republic of Ireland], P=0.022). CONCLUSIONS: In similar neighboring acute stroke populations, differing healthcare policies were associated with significant differences in processes of patient care. Policy reform is an important tool in ensuring optimal stroke care delivery.

Angiographically confirmed coronary heart disease and periodontal disease in middle-aged males.

BACKGROUND: The aim of this study was to investigate whether an association could be demonstrated between coronary heart disease (CHD) and chronic periodontitis in a population of middle-aged males in Northern Ireland. METHODS: A case-control design was used. Cases were men aged over 40 years with angiographically proven CHD. Controls were age-matched males, with no evidence of CHD, randomly drawn from the same locality as the cases. Each subject had a clinical periodontal examination and completed a detailed sociodemographic questionnaire. High sensitivity C-reactive protein (CRP) was measured in serum by immunoturbidimetry. RESULTS: There were 92 cases (mean age 56.7 years; SD = 6.3) and 79 controls (mean age 58.2 years; SD = 6.7). The CHD cases had an average of three teeth less than the controls (P <0.0001). A higher proportion of sites examined in cases than controls had plaque (P = 0.004), bleeding on probing (P = 0.013), and probing depths of > or = 4 mm (P = 0.006) or > or = 6 mm (P = 0.03). Subjects with > or = 4 mm pocketing in more than 20% of their interproximal sites and those with deep pocketing (> or = 6 mm) were classified as having poor periodontal status. A total of 35 cases (38%), compared to only 13 controls (16%), had a poor periodontal status (P = 0.0017). Men with a poor periodontal condition had higher levels of CRP (median 2.19 mg/l) than those with good periodontal health (median 1.42 mg/l), P = 0.007. After adjusting for smoking, academic achievement, alcohol consumption, unemployment, ability to maintain body weight, regular exercise, ability to relax daily, having a hobby or pastime, plaque, and CRP, logistic regression analysis showed that poor periodontal status was significantly associated with CHD, with an adjusted odds ratio of 3.06 and 95% confidence intervals of 1.02 to 9.17, P = 0.046. CONCLUSIONS: There was an association between coronary heart disease and poor periodontal status in the middle-aged males investigated. This association was independent of diabetes and all other cardiovascular risk factors investigated.

Seasonal changes in platelets, fibrinogen and factor VII in elderly people.

BACKGROUND: an increase in mean platelet volume and a decrease in platelet total have been reported following stroke and increased mean platelet volume in acute myocardial infarction has been shown to be predictive of mortality. OBJECTIVE: given the established seasonal variation in morbidity and mortality from cardiovascular disease and various risk factors for the disease, we explored the seasonal variation in mean platelet volume and platelet total. METHODS: we assessed levels of platelet count, platelet volume, fibrinogen, factor VII, core body and ambient temperatures in 54 healthy community dwelling elderly volunteers over a period of 1 year. We used cosinor rhythmometry to quantify and compare the seasonal rhythms. RESULTS: we found significant seasonal variation in fibrinogen, mean platelet volume and core body temperature all of which peaked synchronously in May/June, in a year with an atypically mild winter and hot summer. Platelet total and factor VII did not exhibit a seasonal rhythm. CONCLUSIONS: we conclude that the synchrony between peak size of platelets and peak level of fibrinogen will significantly increase the likelihood of thrombotic events. These results provide further evidence of a seasonal pro-thrombotic state, which has a complex relationship with temperature.
