[Show abstract][Hide abstract] ABSTRACT: Despite high vaccination coverage, a mumps outbreak that affected mainly vaccinated university students and their contacts took place in the Netherlands in the period 2009-2012. We presented university students with a hypothetical case in which we offered them a measles, mumps, and rubella (MMR) booster vaccination to control the mumps outbreak. The aim of this study was to get insight into the determinants of university students' willingness to accept this vaccination.
A questionnaire containing 38 items was developed for the purpose of assessing students' willingness and the psychosocial and social demographic determinants influencing their willingness to accept an MMR booster vaccination. In addition, we explored how organisational characteristics influenced the willingness to be vaccinated. Data were collected at six Dutch universities; a total of 790 students from various faculties were invited to participate. This was a convenience sampling procedure.
687 university students participated (response rate 87.0 %) and 60.4 % of the participants said they would be willing accept the hypothetical MMR booster vaccination. The perceived seriousness of mumps (OR 6.1) was the most important predictor of willingness to accept vaccination. Students who expected the MMR vaccination to be effective and to prevent individual illness and who believed their own vaccination would help stop the epidemic were more likely to be willing than others. The students were more willing to accept vaccination when they perceived that the social norms of significant others and the government favoured vaccination. Organisational characteristics, such as offering vaccination cost free and offering it at the university site, increased students' willingness.
During a mumps outbreak, university students were generally willing to accept a hypothetical MMR booster vaccination. Risk perception, outcome expectations, perceived social norms, and organisational characteristics should be taken into account in the planning of any vaccination campaign for university students during an outbreak of an infectious disease.

[Show abstract][Hide abstract] ABSTRACT: SUMMARY Patients with a lower respiratory tract infection (LRTI) might be at risk for long-term impaired health status. We assessed whether LRTI patients without Q fever are equally at risk for developing long-term symptoms compared to LRTI patients with Q fever. The study was a cross-sectional cohort design. Long-term health status information of 50 Q fever-positive and 32 Q fever-negative LRTI patients was obtained. Health status was measured by the Nijmegen Clinical Screening Instrument. The most severely affected subdomains of the Q fever-positive group were 'general quality of life' (40%) and 'fatigue' (40%). The most severely affected subdomains of the Q fever-negative group were 'fatigue' (64%) and 'subjective pulmonary symptoms' (35%). Health status did not differ significantly between Q fever-positive LRTI patients and Q fever-negative LRTI patients for all subdomains, except for 'subjective pulmonary symptoms' (P = 0·048).

[Show abstract][Hide abstract] ABSTRACT: Objectives:
During the largest Q-fever outbreak ever reported, a cohort study was established to assess the health status of Q-fever patients over a 24-month period and to identify factors associated with health status.
Laboratory-confirmed Q-fever patients participated at six time points after onset of illness. Scores on twelve subdomains from two health status instruments were calculated for each time point to determine progression and compare to reference groups.
The study included 336 Q-fever patients. There is a significant linear improvement over time in nine of the twelve health status subdomains. For example, the proportion of patients with severe fatigue improved from 73.0% at three months to 60.0% at twelve months and 37.0% at twenty-four months, but this was still high compared to a healthy reference group (2.5%). For the three most severely affected subdomains -'Fatigue', 'General Quality of Life' and 'Role Physical'- the baseline characteristics significantly associated with a long-term reduced health status were being female, being a young adult and having pre-existing health problems.
Despite a significant linear improvement over time in nine of the twelve health status subdomains, more than one out of three patients still suffered from a reduced health status at 24 months.

[Show abstract][Hide abstract] ABSTRACT: General practitioners with more positive role security and therapeutic commitment towards patients with hazardous or harmful alcohol consumption are more involved and manage more alcohol-related problems than others. In this study we evaluated the effects of our tailored multi-faceted improvement implementation programme on GPs' role security and therapeutic commitment and, in addition, which professional related factors influenced the impact of the implementation programme.
In a cluster randomised controlled trial, 124 GPs from 82 Dutch general practices were randomised to either the intervention or control group. The tailored, multi-faceted programme included combined physician, organisation, and patient directed alcohol-specific implementation strategies to increase role security and therapeutic commitment in GPs. The control group was mailed the national guideline and patients received feedback letters. Questionnaires were completed before and 12 months after start of the programme. We performed linear multilevel regression analysis to evaluate effects of the implementation programme.
Participating GPs were predominantly male (63%) and had received very low levels of alcohol related education before start of the study (0.4 h). The programme increased therapeutic commitment (p = 0.005; 95%-CI 0.13 - 0.73) but not role security (p = 0.58; 95%-CI -0.31 - 0.54). How important GPs thought it was to improve their care for problematic alcohol consumption, and the GPs' reported proportion of patients asked about alcohol consumption at baseline, contributed to the effect of the programme on therapeutic commitment.
A tailored, multi-faceted programme aimed at improving GP management of patients with hazardous and harmful alcohol consumption improved GPs' therapeutic commitment towards patients with alcohol-related problems, but failed to improve GPs' role security. How important GPs thought it was to improve their care for problematic alcohol consumption, and the GPs' reported proportion of patients asked about alcohol consumption at baseline, both increased the impact of the programme on therapeutic commitment. It might be worthwhile to monitor proceeding of role security and therapeutic commitment throughout the year after the implementation programme, to see whether the programme is effective on short term but faded out on the longer term.Trial registration: ClinicalTrials.gov Identifier: NCT00298220.

[Show abstract][Hide abstract] ABSTRACT: Background:
To define appropriate antibiotic use for patients with a complicated urinary tract infection (UTI), we developed in a previous study a key set of 4 valid, guideline-based quality indicators (QIs). In the current study, we evaluated the association between appropriate antibiotic use for patients with a complicated UTI, as defined by these QIs, and length of hospital stay (LOS).
A retrospective, observational multicenter study included 1252 patients with a complicated UTI, hospitalized at internal medicine and urology departments of 19 university and nonuniversity Dutch hospitals. Data from the patients' medical charts were used to calculate QI performance scores. Multilevel mixed-model analyses were performed to relate LOS to QI performance (appropriate use or not). We controlled for the potential confounders sex, age, (urological) comorbidity, febrile UTI, and intensive care unit admission <24 hours.
Prescribing therapy in accordance with local hospital guidelines was associated with a shorter LOS (7.3 days vs 8.7 days; P = .02), as was early intravenous-oral switching (4.8 days vs 9.1 days; P < .001). There was an inverse relationship between the proportion of appropriate use in a patient (QI sum score/number of applicable QIs) and LOS (9.3 days for lower tertile vs 7.2 days for upper tertile; overall P < .05).
Appropriate antibiotic use in patients with a complicated UTI seems to reduce length of hospital stay and therefore favors patient outcome and healthcare costs. In particular, adherence to the total set of QIs showed a significant dose-response relationship with a shorter LOS.

This study investigates the quality of recording in a general practitioner's (GP) electronic medical record (EMR) compared to a simple, web-based CDR.
The GPs entered data directly in the CDR and in their own EMR during the study period (2011). We extracted data from 58 general practices (8235 patients) with type 2 diabetes and compared the occurrence and value of seven process indicators and 12 outcome indicators in both systems. The CDR, specifically designed for monitoring type 2 diabetes and reporting to health insurers, was used as the reference standard. For process indicators we examined the presence or absence of recordings on the patient level in both systems, for outcome indicators we examined the number of compliant or non-compliant values of recordings present in both systems. The diagnostic OR (DOR) was calculated for all indicators.
We found less concordance for process indicators than for outcome indicators. HbA1c testing was the process indicator with the highest DOR. Blood pressure measurement, urine albumin test, BMI recorded and eye assessment showed low DOR. For outcome indicators, the highest DOR was creatinine clearance <30 mL/min or mL/min/1.73 m(2) and the lowest DOR was systolic blood pressure <140 mm Hg.
Clinical items are not always adequately recorded in an EMR for retrieving indicators, but there is good concordance for the values of these items. If the quality of recording improves, indicators can be reported from the EMR, which will reduce the workload of GPs and enable GPs to maintain a good patient overview.

[Show abstract][Hide abstract] ABSTRACT: To establish which cut-off point for the FEV1/FVC (i.e. fixed 0.70 or Lower Limit of Normal cut-off point) best predicts accelerated lung function decline and exacerbations in middle-aged smokers.We performed secondary analyses on the Lung Health Study dataset. 4,045 smokers aged 35 to 60 years with mild to moderate obstructive pulmonary disease were subdivided into categories based on presence or absence of obstruction according to both FEV1/FVC cut-off points. Postbronchodilator FEV1 decline served as primary outcome to compare subjects between the respective categories.583 subjects (14.4%) were non-obstructed and 3,230 subjects (79.8%) were obstructed according to both FEV1/FVC cut-off points. 173 (4.3%) subjects were obstructive according to the fixed but not according to the LLN cut-off point("discordant" subjects). Mean postbronchodilator FEV1 decline was 41.8 (SE 2.0) mL·year(-1) in non-obstructive subjects, 43.8 (3.8) mL·year(-1) in discordant subjects, and 53.5 (0.9) mL·year(-1) in obstructive subjects (p<0.001).Our study showed that FEV1 decline in subjects deemed obstructed according to a fixed criterion (FEV1/FVC<0.70), but non-obstructed by a sex and age-specific criterion (LLN) closely resembles FEV1 decline in subjects designated as non-obstructed by both criteria. Sex and age should be taken into account when assessing airflow obstruction in middle-aged smokers.

[Show abstract][Hide abstract] ABSTRACT: Aim:
The evidence on the acute effects of smoking on biomarkers is limited. Our aim was to study the acute effect of smoking on disease-related biomarkers.
The acute effect of smoking on serum high sensitivity CRP (hs-CRP) and plasma fibrinogen and its association with disease severity was studied by challenging 31 chronic obstructive pulmonary disease patients with cigarette smoking and repeatedly measuring these biomarkers before and after smoking.
Fibrinogen and hs-CRP increased directly after smoking by 9.4 mg/dl (95% CI: 4.2-14.5) and 0.13 mg/l (95% CI: 0.03-0.23), respectively. Fibrinogen levels remained elevated after 35 min, whereas hs-CRP normalized. Pearson's correlation coefficient between the hs-CRP change and chronic obstructive pulmonary disease severity was 0.25 (p = 0.06).
Fibrinogen and hs-CRP increased directly after smoking in the chronic obstructive pulmonary disease patients. Their association with disease risk and/or progression remains to be demonstrated.

[Show abstract][Hide abstract] ABSTRACT: Purpose:
Screening guidelines for type 2 diabetes recommend targeting high-risk individuals. Our objective was to assess whether diagnosis of type 2 diabetes based on opportunistic targeted screening results in lower vascular event rates compared with diagnosis on the basis of clinical signs or symptoms.
In a prospective, nonrandomized, observational study, we enrolled patients aged 45 to 75 years from 10 family practices in the Netherlands with a new diagnosis of type 2 diabetes, detected either by (1) opportunistic targeted screening (n = 359) or (2) clinical signs or symptoms (n = 206). Patients in both groups received the same guideline-concordant diabetes care. The main group outcome measure was a composite of death from cardiovascular disease (CVD), nonfatal myocardial infarction, and nonfatal stroke.
Baseline vascular disease was more prevalent in the opportunistic targeted screening group, mainly ischemic heart disease (12.3% vs 3.9%, P = .001) and nephropathy (16.9% vs 7.1%, P = .002). After a mean follow-up of 7.7 years (SD = 2.4 years) and 7.1 years (SD = 2.7 years) for the opportunistic targeted screening and clinical diagnosis groups, respectively, composite primary event rates did not differ significantly between the 2 groups (9.5% vs 10.2%, P = .78; adjusted hazard ratio 0.67, 95% confidence interval, 0.36-1.25; P = .21). There were also no significant differences in the separate event rates of deaths from CVD, nonfatal myocardial infarction, and nonfatal strokes.
Opportunistic targeted screening for type 2 diabetes detected patients with higher CVD morbidity at baseline when compared with clinical diagnosis but showed similar CVD mortality and major CVD morbidity after 7.7 years. Opportunistic targeted screening and guided care appears to improve vascular outcomes in type 2 diabetes in primary care.

[Show abstract][Hide abstract] ABSTRACT: Background and objective:
We hypothesized that bronchodilation in patients with chronic obstructive pulmonary disease (COPD) increases the smoke-related risk to develop cardiovascular disease, and aimed to study the effect of short-acting anticholinergic bronchodilation and smoking on cardiovascular events.
We performed a secondary analysis on data from the Lung Health Study, a large randomized clinical trial of smokers with mild to moderate pulmonary obstruction, 35-60 years old, without cardiovascular comorbidity. We used Cox proportional survival analysis, controlling for several confounders, to study the effect on 5-year risk of fatal and/or non-fatal cardiovascular events. Secondary outcome encompassed fatal and non-fatal coronary events.
Of 2745 participants, 23 (0.8%) died of cardiovascular disease. One hundred and sixty-two participants were hospitalized for a cardiovascular event, and 94 participants due to a coronary event. Survival analysis revealed no effect between smoking and short-acting anticholinergic bronchodilation on fatal and/or non-fatal cardiovascular events, hazard ratio = 1.12 (0.58-2.19), nor on coronary events, hazard ratio = 1.46 (0.60-3.56).
Our study results show that short-acting anticholinergic bronchodilation had no detrimental effect on cardiovascular disease in smokers with mild to moderate pulmonary obstruction.
[Show abstract][Hide abstract] ABSTRACT: Background
With increasing age and longevity, the rising number of frail elders with complex and numerous health-related needs demands a coordinated health care delivery system integrating cure, care and welfare. Studies on the effectiveness of such comprehensive chronic care models targeting frail elders show inconclusive results. The CareWell-primary care program is a complex intervention targeting community-dwelling frail elderly people, that aims to prevent functional decline, improve quality of life, and reduce or postpone hospital and nursing home admissions of community dwelling frail elderly.
The CareWell-primary care study includes a (cost-) effectiveness study and a comprehensive process evaluation. In a one-year pragmatic, cluster controlled trial, six general practices are non-randomly recruited to adopt the CareWell-primary care program and six control practices will deliver ‘care as usual’. Each practice includes a random sample of fifty frail elders aged 70 years or above in the cost-effectiveness study. A sample of patients and informal caregivers and all health care professionals participating in the CareWell-primary care program are included in the process evaluation. In the cost-effectiveness study, the primary outcome is the level of functional abilities as measured with the Katz-15 index. Hierarchical mixed-effects regression models / multilevel modeling approach will be used, since the study participants are nested within the general practices. Furthermore, incremental cost-effectiveness ratios will be calculated as costs per QALY gained and as costs weighed against functional abilities. In the process evaluation, mixed methods will be used to provide insight in the implementation degree of the program, patients’ and professionals’ approval of the program, and the barriers and facilitators to implementation.
The CareWell-primary care study will provide new insights into the (cost-) effectiveness, feasibility, and barriers and facilitators for implementation of this complex intervention in primary care.

[Show abstract][Hide abstract] ABSTRACT: To assess the long term effects of two different modes of disease management (comprehensive self management and routine monitoring) on quality of life (primary objective), frequency and patients' management of exacerbations, and self efficacy (secondary objectives) in patients with chronic obstructive pulmonary disease (COPD) in general practice.
24 month, multicentre, investigator blinded, three arm, pragmatic, randomised controlled trial.
15 general practices in the eastern part of the Netherlands.
Patients with COPD confirmed by spirometry and treated in general practice. Patients with very severe COPD or treated by a respiratory physician were excluded.
A comprehensive self management programme as an adjunct to usual care, consisting of four tailored sessions with ongoing telephone support by a practice nurse; routine monitoring as an adjunct to usual care, consisting of 2-4 structured consultations a year with a practice nurse; or usual care alone (contacts with the general practitioner at the patients' own initiative).
The primary outcome was the change in COPD specific quality of life at 24 months as measured with the chronic respiratory questionnaire total score. Secondary outcomes were chronic respiratory questionnaire domain scores, frequency and patients' management of exacerbations measured with the Nijmegen telephonic exacerbation assessment system, and self efficacy measured with the COPD self-efficacy scale.
165 patients were allocated to self management (n=55), routine monitoring (n=55), or usual care alone (n=55). At 24 months, adjusted treatment differences between the three groups in mean chronic respiratory questionnaire total score were not significant. Secondary outcomes did not differ, except for exacerbation management. Compared with usual care, more exacerbations in the self management group were managed with bronchodilators (odds ratio 2.81, 95% confidence interval 1.16 to 6.82) and with prednisolone, antibiotics, or both (3.98, 1.10 to 15.58).
Comprehensive self management or routine monitoring did not show long term benefits in terms of quality of life or self efficacy over usual care alone in COPD patients in general practice. Patients in the self management group seemed to be more capable of appropriately managing exacerbations than did those in the usual care group.

[Show abstract][Hide abstract] ABSTRACT: INTRODUCTION: Bronchodilators are the cornerstone for symptomatic treatment of chronic obstructive pulmonary disease (COPD). Many patients use these agents while persisting in their habit of cigarette smoking. We hypothesized that bronchodilators increase pulmonary retention of cigarette smoke and hence the risk of smoking-related (cardiovascular) disease. Our aim was to investigate if bronchodilation causes increased pulmonary retention of cigarette smoke in patients with COPD. METHODS: A double-blinded, placebo-controlled, randomized crossover trial, in which COPD patients smoked cigarettes during undilated conditions at one session and maximal bronchodilated conditions at the other session. Co-primary outcomes were pulmonary tar and nicotine retention. We performed a secondary analysis that excludes errors due to possible contamination. Secondary outcomes included the biomarkers C-reactive protein and fibrinogen, and smoke inhalation patterns. RESULTS: Of 39 randomized patients, 35 patients completed the experiment and were included in the final analysis. Bronchodilation did not significantly increase tar retention (-4.5%, p = 0.20) or nicotine retention (-2.6%, p = 0.11). Secondary analysis revealed a potential reduction of retention due to bronchodilation: tar retention (-3.8%, p = 0.13), and nicotine retention (-3.4%, p = 0.01). Bronchodilation did not modify our secondary outcomes. CONCLUSIONS: Our results do not support the hypothesis that cigarette tar and nicotine retention in COPD patients is increased by bronchodilation, whereas we observed a possibility towards less retention.

[Show abstract][Hide abstract] ABSTRACT: BACKGROUND: Evidence for pay-for-performance (P4P) has been searched for in the last decade as financial incentives increased to influence behaviour of health care professionals to improve quality of care. The effectiveness of P4P is inconclusive, though some reviews reported significant effects. OBJECTIVE: To assess changes in performance after introducing a participatory P4P program. DESIGN: An observational study with a pre- and post-measurement.Setting and subjects.Sixty-five general practices in the south of the Netherlands.Intervention.A P4P program designed by target users containing indicators for chronic care, prevention, practice management and patient experience (general practitioner's [GP] functioning and organization of care). Quality indicators were calculated for each practice. A bonus with a maximum of 6890 Euros per 1000 patients was determined by comparing practice performance with a benchmark. MAIN OUTCOME MEASURES: Quality indicators for clinical care (process and outcome) and patient experience. RESULTS: We included 60 practices. After 1 year, significant improvement was shown for the process indicators for all chronic conditions ranging from +7.9% improvement for cardiovascular risk management to +11.5% for asthma. Five outcome indicators significantly improved as well as patients' experiences with GP's functioning and organization of care. No significant improvements were seen for influenza vaccination rate and the cervical cancer screening uptake. The clinical process and outcome indicators, as well as patient experience indicators were affected by baseline measures. Smaller practices showed more improvement. CONCLUSIONS: A participatory P4P program might stimulate quality improvement in clinical care and improve patient experiences with GP's functioning and the organization of care.

[Show abstract][Hide abstract] ABSTRACT: Although childhood vaccination programmes have been very successful, there are some hard to reach minority groups that object to vaccination. The Netherlands has experienced several epidemics of vaccine-preventable diseases, confined to the orthodox Protestant minority. However, vaccination coverage in this minority is still unknown and this hampers prevention and control of epidemics.
We estimated vaccination coverage among the orthodox Protestant minority and its various subgroups (denominations), using two sub-studies with different design and study population. For both sub-studies separately, we determined overall vaccination coverage and vaccination coverage per denomination. The results were compared and discussed.
An online survey was filled out by 1778 orthodox Protestant youngsters, invited via orthodox Protestant media using a snowball method. Next to that, results of a national sample study on vaccination were used, of which only orthodox Protestant respondents were included in our analyses (N = 2129). Overall vaccination coverage among orthodox Protestants in The Netherlands was estimated to be at minimum 60%. Moreover, in both sub-studies three clusters of denominations could be identified, with high (>85%), intermediate (50-75%) and low (<25%) vaccination coverage.
The integration of both sub-studies, with their own specific strengths and weaknesses, added to our insight in the vaccination coverage in this minority. Based on these results, we recommend to focus prevention and control of vaccine-preventable diseases on the orthodox Protestant subgroups with intermediate and low vaccination coverage.

[Show abstract][Hide abstract] ABSTRACT: Current COPD guidelines advocate a fixed < 0.70 FEV1/FVC cutpoint to define airflow obstruction. We compared rate of lung function decline in respiratory symptomatic 40+ subjects who were 'obstructive' or 'non-obstructive' according to the fixed and/or age and gender specific lower limit of normal (LLN) FEV1/FVC cutpoints.
We studied 3,324 respiratory symptomatic subjects referred to primary care diagnostic centres for spirometry. The cohort was subdivided into four categories based on presence or absence of obstruction according to the fixed and LLN FEV1/FVC cutpoints. Postbronchodilator FEV1 decline served as primary outcome to compare subjects between the respective categories.
918 subjects were obstructive according to the fixed FEV1/FVC cutpoint; 389 (42%) of them were non-obstructive according to the LLN cutpoint. In smokers, postbronchodilator FEV1 decline was 21 (SE 3) ml/year in those non-obstructive according to both cutpoints, 21 (7) ml/year in those obstructive according to the fixed but not according to the LLN cutpoint, and 50 (5) ml/year in those obstructive according to both cutpoints (p = 0.004).
This study showed that respiratory symptomatic 40+ smokers and non-smokers who show FEV1/FVC values below the fixed 0.70 cutpoint but above their age/gender specific LLN value did not show accelerated FEV1 decline, in contrast with those showing FEV1/FVC values below their LLN cutpoint.

[Show abstract][Hide abstract] ABSTRACT: To assess the effect of a tailored multi-faceted improvement programme on general practitioners' (GPs') behaviour towards prevention of hazardous and harmful alcohol consumption. The improvement programme consisted of activities aimed at the GP, organization and patient. Educational training sessions and visits by a facilitator were tailored to the GPs' needs and attitudes.
Cluster randomized controlled trial.
General practices in the Netherlands.
Seventy-seven general practices; 119 GPs participated. Data from 6318 patients were available, of whom 765 (12.1%) were at risk. A total of 1502 patients' electronic medical records were reviewed.
The primary outcome was the number of eligible patients who received screening and advice.
Difficulties in recruiting GPs and in motivating GPs for participation in the tailored parts of the programme impeded optimal implementation of the programme. Although GPs in both groups became more involved after enrolment, this improvement waned during the trial. The quality improvement programme enhanced the initial improvement in behaviour and it tempered waning (intervention group), compared to our control condition, resulting in average improvement rates of 5% (screening) and 2% (advice-giving) at 12-month follow-up (not significant).
A tailored, multi-faceted programme aimed at improving general practitioner management of alcohol consumption in their patients failed to show an effect and proved difficult to implement. There remains little evidence to support the use of such an intensive implementation programme to improve the management of harmful and hazardous alcohol consumption in primary care.
