GLIM-based malnutrition, protein intake and diet quality in preprocedural Transcatheter Aortic Valve Implantation (TAVI) patients.

BACKGROUND & AIMS: Diagnosed prevalence of malnutrition and dietary intake are currently unknown in patients with severe aortic stenosis planned to undergo Transcatheter Aortic Valve Implantation (TAVI). This study describes the preprocedural nutritional status, protein intake and diet quality. METHODS: Consecutive preprocedural TAVI patients were asked to participate in this explorative study. Nutritional status was diagnosed with the global leadership initiative on malnutrition (GLIM) criteria. Preprocedural protein intake and diet quality were assessed with a three-day dietary record. To increase the record's validity, a researcher visited the participants at their homes to confirm the record. Protein intake was reported as an average intake of three days and diet quality was assessed using the Dutch dietary guidelines (score range 0-14, 1 point for adherence to each guideline). RESULTS: Of the included patients (n = 50, median age 80 ± 5, 56% male) 32% (n = 16) were diagnosed with malnutrition. Patients diagnosed with malnutrition had a lower protein intake (1.02 ± 0.28 g/kg/day vs 0.87 ± 0.21 g/kg/day, p = 0.04). The difference in protein intake mainly took place during lunch (20 ± 13 g/kg vs 13 ± 7 g/kg, p = 0.03). Patients adhered to 6.4 ± 2.2 out of 14 dietary guidelines. Adherence to the guideline of whole grains and ratio of whole grains was lower in the group of patients with malnutrition than in patients with normal nutritional status (both 62% vs 19%, p = 0.01). In a multivariate analysis diabetes mellitus was found as an independent predictor of malnutrition. CONCLUSION: Prevalence of malnutrition among TAVI patients is very high up to 32%. Patients with malnutrition had lower protein and whole grain intake than patients with normal nutritional status. Furthermore, we found diabetes mellitus as independent predictor of malnutrition. Nutrition interventions in this older patient group are highly warranted.

Physical activity, dietary intake and quality of life during COVID-19 lockdown in patients awaiting transcatheter aortic valve implantation.

BACKGROUND: The COVID-19 pandemic has led to a national lockdown in the Netherlands, which also affected transcatheter aortic valve implantation (TAVI) patients. The objective of the study was to describe physical activity, dietary intake and quality of life (QoL) in patients on the waiting list for TAVI pre-lockdown and during lockdown. METHODS: Consecutive patients awaiting TAVI at the Amsterdam University Medical Centers, the Netherlands were included. Measurements were self-reported effect of lockdown, physical activity, dietary intake and QoL. RESULTS: In total, 58 patients (median age 80, interquartile range (IQR) 76-84, 45% female) were observed pre-lockdown and 16 patients (median age 78, IQR 76-82, 25% female) during lockdown. Ten of the 16 patients during lockdown reported a decline in physical activity. However, we observed a median number of 5861 steps a day (IQR 4579-7074) pre-lockdown and 8404 steps a day (IQR 7653-10,829) during lockdown. Median daily protein intake was 69 g (IQR 59-82) pre-lockdown and 90 g (IQR 68-107) during lockdown. Self-rated health on a visual analogue scale was 63 points (IQR 51-74) pre-lockdown and 73 points (IQR 65-86) during lockdown. CONCLUSIONS: More than half of the patients during lockdown reported less physical activity, while we observed a higher number of steps a day, a similar dietary intake and a higher QoL. Therefore, patients on the TAVI waiting list appeared to be able to cope with the lockdown measures.

Medication management during transitions from hospital to home: a focus group study with hospital and primary healthcare providers in the Netherlands.

Background Medication management is jeopardized during a patient's transition from hospital to home. Insight is required from both hospital and primary healthcare providers on how care should be organised to achieve continuity of medication management. Objective This study aimed to identify perspectives of hospital and primary healthcare providers on barriers to the continuity of medication management during a patient's transition from hospital to home and facilitators to overcome these. Setting A qualitative descriptive study was conducted within hospital and primary healthcare settings in the Netherlands. Method Two focus groups were performed with two community care registered nurses, two community pharmacists, four general practitioners, two hospital nurses, two hospital pharmacists, four outpatient pharmacists, two pharmacy technicians, and one physician. A semi-structured interview guide was used to identify perspectives of participants on barriers to continuity of medication management and facilitators to overcome these. Data were analysed following thematic content analysis. Main outcome measure Barriers to the continuity of medication management during a patient's transition from hospital to home would be enumerated, along with facilitators to overcome these barriers. Results Three main themes of barriers and facilitators were identified: (1) healthcare provider collaboration, including the transfer of medication information and effective collaboration; (2) patient's medication use, including information about medication, personalised care, and supervision after discharge; and (3) organisation of healthcare, including the connection between information systems and the supply of medication. Conclusion Barriers and facilitators to continuity of medication management during the transition from hospital to home occur at the provider, patient, and healthcare-system levels. Future interventions should focus on all levels through interprofessional healthcare teams, tailoring care to patient needs, and on the use of a uniform, nationwide patient electronic health record.

Factors related to fear of movement after acute cardiac hospitalization.

BACKGROUND: Fear of movement (kinesiophobia) after an acute cardiac hospitalization (ACH) is associated with reduced physical activity (PA) and non-adherence to cardiac rehabilitation (CR). PURPOSE: To investigate which factors are related to kinesiophobia after an ACH, and to investigate the support needs of patients in relation to PA and the uptake of CR. METHODS: Patients were included 2-3 weeks after hospital discharge for ACH. The level of kinesiophobia was assessed with the Tampa Scale for Kinesiophobia (TSK-NL Heart). A score of > 28 points is defined as 'high levels of kinesiophobia' (HighKin) and ≤ 28 as 'low levels of kinesiophobia' (LowKin). Patients were invited to participate in a semi-structured interview with the fear avoidance model (FAM) as theoretical framework. Interviews continued until data-saturation was reached. All interviews were analyzed with an inductive content analysis. RESULTS: Data-saturation was reached after 16 participants (median age 65) were included in this study after an ACH. HighKin were diagnosed in seven patients. HighKin were related to: (1) disrupted healthcare process, (2) negative beliefs and attitudes concerning PA. LowKin were related to: (1) understanding the necessity of PA, (2) experiencing social support. Patients formulated 'tailored information and support from a health care provider' as most important need after hospital discharge. CONCLUSION: This study adds to the knowledge of factors related to kinesiophobia and its influence on PA and the uptake of CR. These findings should be further validated in future studies and can be used to develop early interventions to prevent or treat kinesiophobia and stimulate the uptake of CR.

The scientific basis for secondary prevention of coronary artery disease: recent contributions from the Netherlands.

While the beneficial effects of secondary prevention of cardiovascular disease are undisputed, implementation remains challenging. A gap between guideline-mandated risk factor targets and clinical reality was documented as early as the 1990s. To address this issue, research groups in the Netherlands have performed several major projects. These projects address innovative, multidisciplinary strategies to improve medication adherence and to stimulate healthy lifestyles, both in the setting of cardiac rehabilitation and at dedicated outpatient clinics. The findings of these projects have led to changes in prevention and rehabilitation guidelines.

Readmission and mortality in patients ≥70 years with acute myocardial infarction or heart failure in the Netherlands: a retrospective cohort study of incidences and changes in risk factors over time.

OBJECTIVES: To determine the risk of first unplanned all-cause readmission and mortality of patients ≥70 years with acute myocardial infarction (AMI) or heart failure (HF) and to explore which effects of baseline risk factors vary over time. METHODS: A retrospective cohort study was performed on hospital and mortality data (2008) from Statistics Netherlands including 5,175 (AMI) and 9,837 (HF) patients. We calculated cumulative weekly incidences for first unplanned all-cause readmission and mortality during 6 months post-discharge and explored patient characteristics associated with these events. RESULTS: At 6 months, 20.4% and 9.9% (AMI) and 24.6% and 22.4% (HF) of patients had been readmitted or had died, respectively. The highest incidences were found in week 1. An increased risk for 14-day mortality after AMI was observed in patients who lived alone (hazard ratio (HR) 1.57, 95% confidence interval (CI) 1.01-2.44) and within 30 and 42 days in patients with a Charlson Comorbidity Index ≥3. In HF patients, increased risks for readmissions within 7, 30 and 42 days were found for a Charlson Comorbidity Index ≥3 and within 42 days for patients with an admission in the previous 6 months (HR 1.42, 95% CI 1.12-1.80). Non-native Dutch HF patients had an increased risk of 14-day mortality (HR 1.74, 95% CI 1.09-2.78). CONCLUSION: The risk of unplanned readmission and mortality in older AMI and HF patients was highest in the 1st week post-discharge, and the effect of some risk factors changed over time. Transitional care interventions need to be provided as soon as possible to prevent early readmission and mortality.

The cardiac care bridge program: design of a randomized trial of nurse-coordinated transitional care in older hospitalized cardiac patients at high risk of readmission and mortality.

BACKGROUND: After hospitalization for cardiac disease, older patients are at high risk of readmission and death. Although geriatric conditions increase this risk, treatment of older cardiac patients is limited to the management of cardiac diseases. The aim of this study is to investigate if unplanned hospital readmission and mortality can be reduced by the Cardiac Care Bridge transitional care program (CCB program) that integrates case management, disease management and home-based cardiac rehabilitation. METHODS: In a randomized trial on patient level, 500 eligible patients ≥ 70 years and at high risk of readmission and mortality will be enrolled in six hospitals in the Netherlands. Included patients will receive a Comprehensive Geriatric Assessment (CGA) at admission. Randomization with stratified blocks will be used with pre-stratification by study site and cognitive status based on the Mini-Mental State Examination (15-23 vs ≥ 24). Patients enrolled in the intervention group will receive a CGA-based integrated care plan, a face-to-face handover with the community care registered nurse (CCRN) before discharge and four home visits post-discharge. The CCRNs collaborate with physical therapists, who will perform home-based cardiac rehabilitation and with a pharmacist who advices the CCRNs in medication management The control group will receive care as usual. The primary outcome is the incidence of first all-cause unplanned readmission or mortality within 6 months post-randomization. Secondary outcomes at three, six and 12 months after randomization are physical functioning, functional capacity, depression, anxiety, medication adherence, health-related quality of life, healthcare utilization and care giver burden. DISCUSSION: This study will provide new knowledge on the effectiveness of the integration of geriatric and cardiac care. TRIAL REGISTRATION: NTR6316 . Date of registration: April 6, 2017.

Smoking cessation in European patients with coronary heart disease. Results from the EUROASPIRE IV survey: A registry from the European Society of Cardiology.

OBJECTIVE: We investigated smoking cessation rates in coronary heart disease (CHD) patients throughout Europe; current and as compared to earlier EUROASPIRE surveys, and we studied characteristics of successful quitters. METHODS: Analyses were done on 7998 patients from the EUROASPIRE-IV survey admitted for myocardial infarction, unstable angina and coronary revascularisation. Self-reported smoking status was validated by measuring carbon monoxide in exhaled air. RESULTS: Thirty-one percent of the patients reported being a smoker in the month preceding hospital admission for the recruiting event, varying from 15% in centres from Finland to 57% from centres in Cyprus. Smoking rates at the interview were also highly variable, ranging from 7% to 28%. The proportion of successful quitters was relatively low in centres with a low number of pre- event smokers. Overall, successful smoking cessation was associated with increasing age (OR 1.50; 95% CI 1.09-2.06) and higher levels of education (OR 1.38; 95% CI 1.08-1.75). Successful quitters more frequently reported that they had been advised (56% vs. 47%, p < .001) and to attend (81% vs. 75%, p < .01) a cardiac rehabilitation programme. CONCLUSION: Our study shows wide variation in cessation rates in a large contemporary European survey of CHD patients. Therefore, smoking cessation rates in patients with a CHD event should be interpreted in the light of pre-event smoking prevalence, and caution is needed when comparing cessation rates across Europe. Furthermore, we found that successful quitters reported more actions to make healthy lifestyle changes, including participating in a cardiac rehabilitation programme, as compared with persistent smokers.

[Secondary prevention of coronary heart disease: results of Euroaspire IV]. / Secundaire preventie van coronaire hartziekte.

OBJECTIVE: Secondary prevention is an important part of cardiovascular risk management. Since 1996, an inventory of cardiovascular risk factors and their treatment has been carried out periodically among patients with coronary heart disease within the framework of the European Action on Secondary Prevention by Intervention to Reduce Events (Euroaspire) project. DESIGN: Retrospective investigation of consecutively hospitalised patients with coronary heart disease. METHOD: Major cardiovascular risk factors and their treatment were investigated using standardised methods in patients who were hospitalised following a first heart infarction or with coronary revascularisation in the Amsterdam and Rijnmond regions of the Netherlands from 2012 to 2013. The investigations were carried out at an average of 18 months after admission. In addition, an oral glucose-tolerance test was carried out in patients without known diabetes. RESULTS: We studied 498 patients. The average BMI was 28 kg/m2, almost 75% had a BMI ≥ 25 kg/m2and 29% had a BMI ≥ 30 kg/m2. The mean cholesterol level was 4.4 mmol/l. Among those included, 16% smoked and 20% had diabetes mellitus; the oral glucose-tolerance test led to a new diabetes-mellitus diagnosis in 1% of the patients without known diabetes. A large majority of those included used antihypertensive agents, and slightly more than half used two or more medications. Despite this, half of the patients were hypertensive. CONCLUSION: As far as cardiovascular risk factors are concerned, smoking has almost halved in the past 20 years. Secondary preventative medication has increased to a stable high level. Blood pressure and overweight continue to be serious points for attention. Treatment of hypertension, in particular, should be improved, for instance by dose increases or combination of hypertensive medications. Routine oral glucose-tolerance tests are not useful in cardiac patients.

Get the Picture: A Pilot Feasibility Study of Telemedical Wound Assessment Using a Mobile Phone in Cardiology Patients.

BACKGROUND: Postprocedural complications after elective cardiac interventions include hematomas and infections. Telemedical wound assessment using mobile phones with integrated cameras may improve quality of care and help reduce costs. AIMS: We aimed to study the feasibility of telemedical wound assessment using a mobile phone. The primary aim was the number of patients who were able to upload their pictures. Secondary aims were image interpretability, agreement between nurse practitioners, and patient evaluation of the intervention. METHODS: This is a prospective study of all consecutive patients who underwent an elective cardiac intervention. Patients were instructed to photograph their wound or puncture site after hospital discharge and upload the pictures to a secure email address 6 days after hospital discharge. Received photos were assessed by 2 nurse practitioners. The intervention was evaluated using a peer-reviewed questionnaire and photo assessment scheme. RESULTS: In total, 46 eligible patients were included in the study, with 5 screen failures (eg, clinical stay ≥ 6 days) and 1 patient lost to follow-up. Thirty-three of 40 patients (83%) were able to upload their pictures. Smartphone users were more successful in uploading their pictures compared with feature phone users (93% vs 55%, P < .01). Eighty-eight percent of the clinical pictures were interpretable. The interobserver variability had an agreement between 93% and 97%. CONCLUSIONS: Patients are able to take and upload the mobile clinical photos to the secure email address, and the vast majority was interpretable. Smartphone users were more successful than feature phone users in uploading their pictures. The interobserver variability was good.

Nurses' perspectives on nurse-coordinated prevention programmes in secondary prevention of cardiovascular disease: a pilot survey.

BACKGROUND: Secondary prevention of coronary artery disease (CAD) is increasingly provided by nurse-coordinated prevention programs (NCPP). Little is known about nurses' perspectives on these programs. AIM: To investigate nurses' perspectives/experiences in NCPPs in acute coronary syndrome patients. METHODS: Thirteen nurses from NCPPs in 11 medical centers in the RESPONSE trial completed an online survey containing 45 items evaluating 3 outcome categories: (1) conducting NCPP visits; (2) effects of NCPP interventions on risk profiles and (3) process of care. RESULTS: Nurses felt confident in counseling/motivating patients to reduce CAD risk. Interventions targeting LDL, blood pressure and medication adherence were reported as successful, corresponding with significant improvements of these risk factors. Improving weight, smoking and physical activity was reported as less effective. Screening for anxiety/depression was suggested as an improvement. CONCLUSIONS: Nurses acknowledge the importance and effectiveness of NCPPs, and correctly identify which components of the program are the most successful. Our study provides a basis for implementation and quality improvement for NCCPs.

Smoking cessation after an acute coronary syndrome: immediate quitters are successful quitters.

BACKGROUND: Cardiovascular disease (CVD) prevention guidelines stress the importance of smoking cessation and recommend intensive follow-up. To guide the development of such cessation support strategies, we analysed the characteristics that are associated with successful smoking cessation after an acute coronary syndrome (ACS). METHODS: We used data from the Randomised Evaluation of Secondary Prevention for ACS patients coordinated by Outpatient Nurse SpEcialists (RESPONSE) trial (n = 754). This was designed to quantify the impact of a nurse-coordinated prevention program, focusing on healthy lifestyles, traditional CVD risk factors and medication adherence. For the current analysis we included all smokers (324/754, 43 %). Successful quitters were defined as those who reported abstinence at 1 year of follow-up. RESULTS: The majority of successful quitters quit immediately after the ACS event and remained abstinent through 1 year of follow-up, without extra support (128/156, 82 %). Higher education level (33 vs. 15 %, p < 0.01), no history of CVD (87 vs. 74 %, p < 0.01) and being on target for LDL-cholesterol level at 1 year (78 vs. 63 %, p < 0.01) were associated with successful quitting. CONCLUSION: The majority of successful quitters at 1 year stopped immediately after their ACS. Patients in this group showed that it was within their own ability to quit, and they did not relapse through 1 year of follow-up. Our study indicates that in a large group of patients who quit immediately after a life-threatening event, no relapse prevention program is needed.

Gender disparities in disease-specific health status in postoperative patients with peripheral arterial disease.

OBJECTIVES: To investigate gender disparities in disease-specific health status (HS), 3- and 5-year post-intervention in peripheral arterial disease (PAD) patients. DESIGN: Cohort study. METHODS: Data of 711 consecutively enrolled vascular surgery patients were collected in 11 hospitals in The Netherlands in 2004. HS was assessed with the Peripheral Artery Questionnaire (PAQ). Our sample included patients for whom it was possible to calculate a PAQ summary score at 3- and 5-year follow-up (n = 351). RESULTS: Women experienced worse physical health (52.1 vs. 62.0, P = 0.012), greater disability (64.5 vs. 71.1, P = 0.026), and worse overall HS (58.1 vs. 66.7, P = 0.007) at 3-year follow-up than men. At 5-year follow-up, however, male and female patients reported similar levels of HS. Mean changes in overall HS from 3- to 5-year follow-up were significantly different for men and women (-4.12 vs. 1.69, P = 0.014). In male patients, overall HS was significantly lower at 5-year follow-up compared to the 3-year follow-up (66.7 vs. 62.6, P = 0.001). In female patients, there was no significant difference (58.1 vs. 59.8, P = 0.393). CONCLUSIONS: Men and women experience different levels of HS over time. Attention should be paid to gender disparities in postoperative PAD patients.

Acceptance of insulin therapy: a long shot? Psychological insulin resistance in primary care.

AIM: To explore which factors are associated with psychological insulin resistance in insulin-naive patients with Type 2 diabetes in primary care. METHODS: A sample of 101 insulin-naive patients with Type 2 diabetes completed self-administered questionnaires including demographic and clinical characteristics, the Insulin Treatment Appraisal Scale and the Center for Epidemiological Studies Depression scale. Psychological insulin resistance was denoted by negative appraisal of insulin (Insulin Treatment Appraisal Scale). RESULTS: Thirty-nine per cent of the sample were unwilling to accept insulin therapy. Unwilling participants perceived taking insulin more often as a failure to control their diabetes with tablets or lifestyle compared with willing participants (59 vs. 33%), unwilling participants were more reluctant to accept the responsibilities of everyday management of insulin therapy (49 vs. 24%). Multiple linear regression analysis revealed that depression and objection to lifelong insulin therapy were independently associated with psychological insulin resistance. CONCLUSIONS: In this study in primary care, depression and objection to lifelong insulin therapy are associated with psychological insulin resistance. Analysis of the objection to the indefiniteness of insulin therapy showed a sense of limitation of daily life and loss of independence that should not be underestimated. Insulin should be offered as a means to improve health as this might facilitate the acceptance of insulin therapy.

Smoking cessation has no influence on quality of life in patients with peripheral arterial disease 5 years post-vascular surgery.

OBJECTIVES: Smoking is an important modifiable risk factor in patients with peripheral arterial disease (PAD). We investigated differences in quality of life (QoL) between patients who quitted smoking during follow-up and persistent smokers. DESIGN: Cohort study. METHODS: Data of 711 consecutively enrolled patients undergoing vascular surgery were collected in 11 hospitals in the Netherlands. Smoking status was obtained at baseline and at 3-year follow-up. A 5-year follow-up to measure QoL was performed with the EuroQol-5D (EQ-5D) and Peripheral Arterial Questionnaire (PAQ). RESULTS: After adjusting for clinical risk factors, patients, who quit smoking within 3 years after vascular surgery, did not report an impaired QoL (EQ-5D: odds ratio (OR) = 0.63, 95% confidence interval (CI) = 0.28-1.43; PAQ: OR = 0.76, 95% CI = 0.35-1.65; visual analogue scale (VAS): OR = 0.88, 95% CI = 0.42-1.84) compared with patients, who continued smoking. Current smokers were significantly more likely to have an impaired QoL (EQ-5D: OR = 1.86, 95% CI = 1.09-3.17; PAQ: OR = 1.63, 95% CI = 1.00-2.65), although no differences in VAS scores were found (OR = 1.17, 95% CI = 0.72-1.90). CONCLUSIONS: There was no effect of smoking cessation on QoL in PAD patients undergoing vascular surgery. Nevertheless, given the link between smoking, complications and mortality in this patient group, smoking cessation should be a primary target in secondary prevention.

Process of care partly explains the variation in mortality between hospitals after peripheral vascular surgery.

OBJECTIVES: The aim of this study is to investigate whether variation in mortality at hospital level reflects differences in quality of care of peripheral vascular surgery patients. DESIGN: Observational study. MATERIALS: In 11 hospitals in the Netherlands, 711 consecutive vascular surgery patients were enrolled. METHODS: Multilevel logistic regression models were used to relate patient characteristics, structure and process of care to mortality at 1 year. The models were constructed by consecutively adding age, sex and Lee index, then remaining risk factors, followed by structural measures for quality of care and finally, selected process of care parameters. RESULTS: Total 1-year mortality was 11%, ranging from 6% to 26% in different hospitals. Large differences in patient characteristics and quality indicators were observed between hospitals (e.g., age>70 years: 28-58%; beta-blocker therapy: 39-87%). Adjusted analyses showed that a large part of variation in mortality was explained by age, sex and the Lee index (Akaike's information criterion (AIC)=59, p<0.001). Another substantial part of the variation was explained by process of care (AIC=5, p=0.001). CONCLUSIONS: Differences between hospitals exist in patient characteristics, structure of care, process of care and mortality. Even after adjusting for the patient population at risk, a substantial part of the variation in mortality can be explained by differences in process measures of quality of care.

Antibiotic-based catheter lock solutions for prevention of catheter-related bloodstream infection: a systematic review of randomised controlled trials.

Catheter-related bloodstream infection (CRBSI) is associated with high rates of morbidity. This systematic review assesses the efficacy of antibiotic-based lock solutions to prevent CRBSI. A secondary goal of our review is to determine which antibiotic-based lock solution is most effective in reducing CRBSI. We searched Medline and the Cochrane Library for relevant trials up to April 2009. Data from the original publications were used to calculate the overall relative risk of CRBSI. Data for similar outcomes were combined in the analysis where appropriate, using a random-effects model. Sixteen trials were included in the review, nine conducted in haemodialysis patients, six in oncology patients (mainly children) and one study concerned critically ill neonates. Three haemodialysis patients needed to be treated with antibiotics to prevent one CRBSI, given a mean insertion time of 146 days (range: 37-365) and an average baseline risk of 3.0 events per 1000 catheter-days. In the oncology patients a number needed to treat (NNT) was calculated of eight patients to prevent one BSI, given a mean insertion time of 227 days (range: 154-295) and average baseline risk of 1.7 events per 1000 catheter-days. There are indications that antibiotic-based lock solutions as compared to heparin lock solutions are effective in the prevention of CRBSI in haemodialysis patients. In trials studying oncology patients the estimated effect showed only a marginal significant benefit in favour of antibiotic-based lock solutions. Our review supports the Centers for Disease Control and Prevention in not recommending routine use of antibiotic-based catheter lock solutions.

Statin treatment after a recent TIA or stroke: is effectiveness shown in randomized clinical trials also observed in everyday clinical practice?

AIM AND BACKGROUND: The benefit of statin treatment in patients with a previous ischemic stroke or transient ischemic attack (TIA) has been demonstrated in randomized clinical trials (RCT). However, the effectiveness in everyday clinical practice may be decreased because of a different patient population and less controlled setting. We aim to describe statin use in an unselected cohort of patients, identify factors related to statin use and test whether the effect of statins on recurrent vascular events and mortality observed in RCTs is also observed in everyday clinical practice. METHODS: In 10 centers in the Netherlands, patients admitted to the hospital or visiting the outpatient clinic with a recent TIA or ischemic stroke were prospectively and consecutively enrolled between October 2002 and May 2003. Statin use was determined at discharge and during follow-up. We used logistic regression models to estimate the effect of statins on the occurrence of vascular events (stroke or myocardial infarction) and mortality within 3 years. We adjusted for confounders with a propensity score that relates patient characteristics to the probability of using statins. RESULTS: Of the 751 patients in the study, 252 (34%) experienced a vascular event within 3 years. Age, elevated cholesterol levels and other cardiovascular risk factors were associated with statin use at discharge. After 3 years, 109 of 280 (39%) of the users at discharge had stopped using statins. Propensity score adjusted analyses showed a beneficial effect of statins on the occurrence of the primary outcome (odds ratio 0.8, 95% CI: 0.6-1.2). CONCLUSION: In our study, we found poor treatment adherence to statins. Nevertheless, after adjustment for the differences between statin users and non-statin users, the observed beneficial effect of statins on the occurrence of vascular events within 3 years, although not statistically significant, is compatible with the effect observed in clinical trials.

Comparing and ranking hospitals based on outcome: results from The Netherlands Stroke Survey.

BACKGROUND: Measuring quality of care and ranking hospitals with outcome measures poses two major methodological challenges: case-mix adjustment and variation that exists by chance. AIM: To compare methods for comparing and ranking hospitals that considers these. METHODS: The Netherlands Stroke Survey was conducted in 10 hospitals in the Netherlands, between October 2002 and May 2003, with prospective and consecutive enrollment of patients with acute brain ischaemia. Poor outcome was defined as death or disability after 1 year (modified Rankin scale of > or =3). We calculated fixed and random hospital effects on poor outcome, unadjusted and adjusted for patient characteristics. We compared the hospitals using the expected rank, a novel statistical measure incorporating the magnitude and the uncertainty of differences in outcome. RESULTS: At 1 year after stroke, 268 of the total 505 patients (53%) had a poor outcome. There were substantial differences in outcome between hospitals in unadjusted analysis (chi(2) = 48, 9 df, P < 0.0001). Adjustment for 12 confounders led to halving of the chi(2) (chi(2) = 24). The same pattern was observed in random effects analysis. Estimated performance of individual hospitals changed considerably between unadjusted and adjusted analysis. Further changes were seen with random effect estimation, especially for smaller hospitals. Ordering by expected rank led to shrinkage of the original ranks of 1-10 towards the median rank of 5.5 and to a different order of the hospitals, compared to ranking based on fixed effects. CONCLUSION: In comparing and ranking hospitals, case-mix-adjusted random effect estimates and the expected ranks are more robust alternatives to traditional fixed effect estimates and simple rankings.

[Differences between hospitals in outcome after a stroke are only partially explained by differences in the quality of care]. / Verschillen tussen ziekenhuizen in uitkomst na een herseninfarct vooral verklaard door patiëntkenmerken en slechts ten dele door verschillen in de kwaliteit van zorg.

OBJECTIVE: To determine the extent to which the outcome of stroke patients stroke is correlated with patient characteristics and care process parameters, and to determine whether outcome measures can be used to measure the quality of hospital care provided for these patients. DESIGN: Descriptive cohort study. METHODS: At 10 hospitals in the Netherlands, in the period October 2002-April 2003, patients with acute stroke were included in the study. Poor outcome was defined as dead or disabled at 1 year (a score on the modified Rankin scale > or = 3). Quality of the care was assessed by relating diagnostic, therapeutic and preventive procedures to indication. Multiple logistic regression models were used to compare observed numbers of patients with a poor outcome with expected numbers per hospital, after adjustment for patient characteristics and quality of care parameters. RESULTS: In total, 579 patients were included in the study, of which 271 (47%) were dead or disabled at 1 year. Poor outcome varied across the hospitals from 29 to 78%. The mean age was 70 years. There were large differences between hospitals with respect to patient characteristics and quality of care. Most of the differences in outcome between hospitals were explained by the differences in patient characteristics (Akaike's information criterion (AIC) = 134). Quality of care parameters explained just a small additional part of the variation in patient outcome (AIC = 5.5). CONCLUSIONS: Large differences between Dutch hospitals in the patient outcome after stroke could mostly be explained by differences in patient characteristics. Only a small part of the hospital variation in patient outcome was related to differences in quality of care. Therefore, outcome indicators cannot be regarded as valid performance indicators for care following a stroke.
