Exploring and Evaluating Patient Safety Culture in a Community-Based Primary Care Setting.

OBJECTIVES: The primary aim was to measure patient safety culture in two home care services in Belgium (Flanders). In addition, variability based on respondents' profession was examined. METHODS: A cross-sectional study was conducted by administering the SCOPE-Primary Care questionnaire in two home care service organizations. RESULTS: In total, 1875 valid questionnaires were returned from 2930 employees, representing a response rate of 64%. The highest mean patient safety culture score was found for "organizational learning" (mean [SD] = 3.81 [0.53]), followed by "support and fellowship" (mean [SD] = 3.76 [0.61]), "open communication and learning from error" (mean [SD] = 3.73 [0.64]), and "patient safety management" (mean [SD] = 3.71 [0.60]). The lowest mean scores were found for "handover and teamwork" (mean [SD] = 3.28 [0.58]) and "adequate procedures and working conditions" (mean [SD] = 3.30 [0.56]). Moreover, managers/supervisors scored significantly higher on the dimensions "open communication and learning from error," "adequate procedures and working conditions," "patient safety management," "support and fellowship," and "organizational learning" than clinical and nonclinical staff. CONCLUSIONS: In conclusion, organizational learning is perceived as most positive. However, large gaps remain in the continuity of care as "handover and teamwork" is perceived as the most negative safety culture dimension. With knowledge of the current patient safety culture, organizations can redesign processes or implement improvement strategies to avoid patient safety incidents and patient harm in the future.

General practitioners' predictions of their own patients' health literacy: a cross-sectional study in Belgium.

OBJECTIVES: To support patients in their disease management, providing information that is adjusted to patients' knowledge and ability to process health information (ie, health literacy) is crucial. To ensure effective health communication, general practitioners (GPs) should be able to identify people with limited health literacy. To this end, (dis)agreement between patients' health literacy and GPs' estimations thereof was examined. Also, characteristics impacting health literacy (dis)agreement were studied. DESIGN: Cross-sectional survey of general practice patients and GPs undertaken in 2016-17. SETTING: Forty-one general practices in two Dutch-speaking provinces in Belgium. PARTICIPANTS: Patients (18 years of age and older) visiting general practices. Patients were excluded when having severe impairments (physical, mental, sensory). MAIN OUTCOME MEASURES: Patients' health literacy was assessed with 16-item European Health Literacy Survey Questionnaire. GPs indicated estimations on patients' health literacy using a simple scale (inadequate; problematic; adequate). (Dis)agreement between patients' health literacy and GPs' estimations thereof (GPs' estimations being equal to/higher/lower than patients' health literacy) was measured using Kappa statistics. The impact of patient and GP characteristics, including duration of GP-patient relationships, on this (dis)agreement was examined using generalised linear logit model. RESULTS: Health literacy of patients (n=1375) was inadequate (n=201; 14.6%), problematic (n=299; 21.7%), adequate (n=875; 63.6%). GPs overestimated the proportion patients with adequate health literacy: adequate (n=1241; 90.3%), problematic (n=130; 9.5%) and inadequate (n=4; 0.3%). Overall, GPs' correct; over-/underestimations of health literacy occurred for, respectively, 60.9%; 34.2%; 4.9% patients, resulting in a slight agreement (κ=0.033). The likelihood for GPs to over-/underestimate patients' health literacy increases with decreasing educational level of patients; and decreasing number of years patients have been consulting with their GP. CONCLUSIONS: Intuitively assessing health literacy is difficult. Patients' education, the duration of GP-patient relationships and GPs' gender impact GPs' perceptions of patients' health literacy.

Personality of Belgian physicians in a clinical leadership program.

BACKGROUND: Physician and non-physician leadership development programs aim to improve organizational performance. Although a significant, positive relation between physicians' leadership skills and patient outcomes, staff satisfaction and staff retention has been found, physicians are not formally trained in clinical leadership skills during their physician training. A lot of current healthcare leaders were chosen to take on leadership because of their productivity, published research, solid clinical skills, or because they were great educators, Heifetz RA. Leadership Without Easy Answers; 1994 although they often do not have the skills to build a team, resulting in dysfunctional teams and having to deal with conflicts and chaos. The first steps of a Clinical Leadership Program is to gain insight in one's personality, one's personal skills and one's leadership growth potential, because this gives information on one's natural leadership style. The aim of our research is to gain insight in the personality traits of healthcare professionals who are leading teams and to check (a) whether Belgian physicians with leadership ambition, share certain preferences, (b) whether physicians differ from other healthcare staff in terms of personality, (c) whether our sample of Belgian physicians differs from a population of physicians in the United States of America. METHODS: In-hospital physicians and non-physicians enrolled in a Clinical Leadership Program consented to participate. They explored their personal preferences across four dimensions, based on the Myers-Briggs Type Indicator (MBTI). Their most suitable MBTI profile was determined with a self-assessment and a complementary guidance of an MBTI-coach. Chi-squared tests and logistic regression were performed to check distributions across different MBTI-dimensions and to assess the relation with profession and location. RESULTS: Among participating physicians significantly more preferences for 'Thinking' then for 'Feeling' were found. Non-physicians were found to be significantly more 'Sensing' and 'Judging' compared with physicians. No significant differences were found between physicians from our (Belgian) and the USA dataset. CONCLUSION: Preferences of physicians proved to be different from those of non-physicians. 'ISTJ' is the most frequent personality profile both in Belgian and USA physicians.

The SCOPE-PC instrument for assessing patient safety culture in primary care: a psychometric evaluation.

INTRODUCTION: Primary healthcare differs from hospitals in terms of - inter alia - organisational structure. Therefore, patient safety culture could differ between these settings. Various instruments have been developed to measure collective attitudes of personnel within a primary healthcare organisation. However, the number of valid and reliable instruments is limited. OBJECTIVES: Psychometric properties of the SCOPE-Primary Care instrument were tested to examine the instrument's applicability in home care services in Belgium. METHODS: A cross-sectional study was conducted by administering the SCOPE-PC questionnaire in a single home care organisation with more than 1000 employees, including nurses, midwives, healthcare assistants, diabetes educators and nursing supervisors. First, a confirmatory factor analysis was performed to test whether the observed dataset fitted to the proposed seven-factor model of the SCOPE-PC instrument. Second, Cronbach's alphas were calculated to examine internal consistency reliability. Finally, the instrument's validity was also examined. RESULTS: In total, 603 questionnaires were retained for further analysis, representing an overall response rate of 43.9%. Most respondents were nursing staff, followed by healthcare assistants and nursing supervisors. The results of the confirmatory factor analyses satisfied the chosen cut-offs, indicating an acceptable to good model fit. With the exception of the dimension 'organizational learning' (0.58), Cronbach's alpha scores of the SCOPE-PC scales indicated a good level of internal consistency: 'open communication and learning from error' (0.86), 'handover and teamwork' (0.78), 'adequate procedures and working conditions' (0.73), 'patient safety management' (0.81), 'support and fellowship' (0.75), and 'intention to report events (0.85). Moreover, inter-correlations between the seven dimensions as well as with the patient safety grade were moderate to good. CONCLUSIONS: The present study indicated that the SCOPE-Primary Care instrument has good psychometric properties for home care services in Belgium. No modifications are required to the original questionnaire in order to allow benchmarking between primary healthcare settings.

General practitioners' and primary care nurses' care for people with disabilities: quality of communication and awareness of supportive services.

BACKGROUND: General practitioners (GPs) and primary-care nurses (PCNs) often feel inexperienced or inadequately educated to address unmet needs of people with disabilities (PDs). In this research, GPs' and PCNs' communication with PDs and health care professionals, as well as their awareness of supportive measures relevant to PDs (sensory disabilities excluded), was examined. MATERIALS AND METHODS: An electronic questionnaire was sent out to 545 GPs and 1,547 PCNs employed in Limburg (Belgium). GPs and PCNs self-reported about both communication with parties involved in care for PDs (scale very good, good, bad, very bad) and their level of awareness of supportive measures relevant for PDs (scale unaware, inadequately aware, adequately aware). RESULTS: Of the questionnaire recipients, 6.6% (36 of 545) of GPs and 37.6% (588 of 1,547) of PCNs participated: 68.8% of 32 GPs and 45.8% of 443 PCNs categorized themselves as communicating well with PDs, and attributed miscommunication to limited intellectual capacities of PDs. GPs and PCNs reported communicating well with other health care professionals. Inadequate awareness was reported for tools to communicate (88.3% of GPs, 89% of PCNs) and benefits for PDs (44.1% of GPs, 66.9% of PCNs). CONCLUSION: GPs' and PCNs' lacking awareness of communication aids is problematic. Involvement in a multidisciplinary, expert network might bypass inadequate awareness of practical and social support measures.

Measuring health literacy among low literate people: an exploratory feasibility study with the HLS-EU questionnaire.

BACKGROUND: Health literacy (HL) is defined as necessary competencies to make well-informed decisions. As patients' decision making is a key element of patient-centered health care, insight in patients' HL might help healthcare professionals to organize their care accordingly. This is particularly true for people in a vulnerable situation, potentially with limited HL, who are, for instance, at greater risk of having limited access to care [1, 2]. As HL correlates with education, instruments should allow inclusion of low literate people. To that end, the relatively new instrument, HLS-EU-Q47, was subjected to a comprehensibility test, its shorter version, HLS-EU-Q16, was not. Therefore, the goal of this study was to examine feasibility of HLS-EU-Q16 (in Dutch) for use in a population of people with low literacy. METHODS: Purposive sampling of adults with low (yearly) income (< €16,965.47) and limited education (maximum high school), with Dutch language proficiency. Exclusion criteria were: psychiatric, neurodegenerative diseases or impairments. To determine suitability (length, comprehension and layout) participants were randomly distributed either HLS-EU-Q16 or a modified version and were interviewed directly afterwards by one researcher. To determine feasibility a qualitative approach was chosen: cognitive interviews were carried out using the verbal probing technique. RESULTS: Thirteen participants completed HLS-EU-Q16 (n = 7) or the modified version (n = 6). Questions about 'disease prevention' or 'appraisal' of information are frequently reported to be incomprehensible. Difficulties are attributed to vocabulary, sentence structure and the decision process (abstraction, distinguishing 'appraising' from 'applying' information, indecisive on the appropriate response). CONCLUSIONS: HLS-EU-Q16 is a suitable instrument to determine HL in people with limited literacy. However, to facilitate the use and interpretation, some questions would benefit from minor adjustments: by simplifying wording or providing explanatory, contextual information.

Prevalence of inappropriate medication use in residential long-term care facilities for the elderly: A systematic review.

BACKGROUND: Multi-morbidity and polypharmacy of the elderly population enhances the probability of elderly in residential long-term care facilities experiencing inappropriate medication use. OBJECTIVES: The aim is to systematically review literature to assess the prevalence of inappropriate medication use in residential long-term care facilities for the elderly. METHODS: Databases (MEDLINE, EMBASE) were searched for literature from 2004 to 2016 to identify studies examining inappropriate medication use in residential long-term care facilities for the elderly. Studies were eligible when relying on Beers criteria, STOPP, START, PRISCUS list, ACOVE, BEDNURS or MAI instruments. Inappropriate medication use was defined by the criteria of these seven instruments. RESULTS: Twenty-one studies met inclusion criteria. Seventeen studies relied on a version of Beers criteria with prevalence ranging between 18.5% and 82.6% (median 46.5%) residents experiencing inappropriate medication use. A smaller range, from 21.3% to 63.0% (median 35.1%), was reported when considering solely the 10 studies that used Beers criteria updated in 2003. Prevalence varied from 23.7% to 79.8% (median 61.1%) in seven studies relying on STOPP. START and ACOVE were relied on in respectively four (prevalence: 30.5-74.0%) and two studies (prevalence: 28.9-58.0%); PRISCUS, BEDNURS and MAI were all used in one study each. CONCLUSIONS: Beers criteria of 2003 and STOPP were most frequently used to determine inappropriate medication use in residential long-term care facilities. Prevalence of inappropriate medication use strongly varied, despite similarities in research design and assessment with identical instrument(s).

A multicenter record review of in-hospital adverse drug events requiring a higher level of care.

OBJECTIVE: Adverse drug events (ADEs) are a worldwide concern, particularly when leading to a higher level of care. This study defines a higher level of care as an unplanned (re)admission to an intensive care unit or an intervention by a Medical Emergency Team. The objectives are to describe the incidence and preventability of ADEs leading to a higher level of care, to assess the types of drug involved, and to identify the risk factors. METHODS: A three-stage retrospective review was performed in six Belgian hospitals. Patient records were assessed by a trained clinical team consisting of a nurse, a physician, and a clinical pharmacist. Descriptive statistics, univariate, and multiple logistic regressions were used. RESULTS: In this study, 830 patients were detected for whom a higher level of care had been needed. In 160 (19.3%) cases, an ADE had occurred; 134 (83.8%) of these were categorized as preventable adverse drug events (pADEs). The overall incidence rate of patients transferred to a higher level of care because of a pADE was 33.9 (95% CI: 28.5-39.3) per 100,000 patient days at risk. Antibiotics and antithrombotic agents accounted both for one-fifth of all pADEs. Multivariate analysis indicated American Society of Anaesthesiologists physical status score as a risk factor for pADEs. CONCLUSIONS: The high number of pADE with patient harm shows that there is a need for structural improvement of pharmacotherapeutic care. Detection of these pADEs can be the basis for the implementation of these improvements.

Validation of a single-stage fixed-rate step test for the prediction of maximal oxygen uptake in healthy adults.

Healthcare professionals with limited access to ergospirometry remain in need of valid and simple submaximal exercise tests to predict maximal oxygen uptake (VO2max ). Despite previous validation studies concerning fixed-rate step tests, accurate equations for the estimation of VO2max remain to be formulated from a large sample of healthy adults between age 18-75 years (n > 100). The aim of this study was to develop a valid equation to estimate VO2max from a fixed-rate step test in a larger sample of healthy adults. A maximal ergospirometry test, with assessment of cardiopulmonary parameters and VO2max , and a 5-min fixed-rate single-stage step test were executed in 112 healthy adults (age 18-75 years). During the step test and subsequent recovery, heart rate was monitored continuously. By linear regression analysis, an equation to predict VO2max from the step test was formulated. This equation was assessed for level of agreement by displaying Bland-Altman plots and calculation of intraclass correlations with measured VO2max . Validity further was assessed by employing a Jackknife procedure. The linear regression analysis generated the following equation to predict VO2max (l min(-1) ) from the step test: 0·054(BMI)+0·612(gender)+3·359(body height in m)+0·019(fitness index)-0·012(HRmax)-0·011(age)-3·475. This equation explained 78% of the variance in measured VO2max (F = 66·15, P<0·001). The level of agreement and intraclass correlation was high (ICC = 0·94, P<0·001) between measured and predicted VO2max . From this study, a valid fixed-rate single-stage step test equation has been developed to estimate VO2max in healthy adults. This tool could be employed by healthcare professionals with limited access to ergospirometry.

Incidence and outcome of inappropriate in-hospital empiric antibiotics for severe infection: a systematic review and meta-analysis.

INTRODUCTION: The aims of this study were to explore the incidence of in-hospital inappropriate empiric antibiotic use in patients with severe infection and to identify its relationship with patient outcomes. METHODS: Medline (from 2004 to 2014) was systematically searched by using predefined inclusion criteria. Reference lists of retrieved articles were screened for additional relevant studies. The systematic review included original articles reporting a quantitative measure of the association between the use of (in)appropriate empiric antibiotics in patients with severe in-hospital infections and their outcomes. A meta-analysis, using a random-effects model, was conducted to quantify the effect on mortality by using risk ratios. RESULTS: In total, 27 individual articles fulfilled the inclusion criteria. The percentage of inappropriate empiric antibiotic use ranged from 14.1% to 78.9% (Q1-Q3: 28.1% to 57.8%); 13 of 27 studies (48.1%) described an incidence of 50% or more. A meta-analysis for 30-day mortality and in-hospital mortality showed risk ratios of 0.71 (95% confidence interval 0.62 to 0.82) and 0.67 (95% confidence interval 0.56 to 0.80), respectively. Studies with outcome parameter 28-day and 60-day mortality reported significantly (P ≤0.02) higher mortality rates in patients receiving inappropriate antibiotics. Two studies assessed the total costs, which were significantly higher in both studies (P ≤0.01). CONCLUSIONS: This systematic review with meta-analysis provides evidence that inappropriate use of empiric antibiotics increases 30-day and in-hospital mortality in patients with a severe infection.

Measuring safety culture in belgian psychiatric hospitals: validation of the dutch and French translations of the hospital survey on patient safety culture.

OBJECTIVES: To measure safety culture in Belgian psychiatric hospitals on 12 dimensions and to examine the psychometric properties of the Dutch and French translations of the Hospital Survey on Patient Safety Culture (HSPSC) for use in psychiatric hospitals. METHODS: The authors analyzed 6,658 completed questionnaires (70.5% response rate) from a baseline measurement (2007-2009) in 44 psychiatric hospitals and 8,353 questionnaires (71.5% response rate) from a follow-up measurement (2011) in 46 psychiatric hospitals. Psychometric properties of the questionnaire were evaluated using item analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), reliability analysis (Cronbach's alpha), and analysis of composite scores and inter-correlations. RESULTS: For both translations, CFA showed an acceptable fit with the original 12-dimensional model. For the Dutch and French translations, EFA showed a 10-factor and a 9-factor optimal measurement model, respectively. Cronbach's alpha indicated an acceptable level of reliability (≥ 0.70) for 7 of 12 dimensions. Most pair-wise correlations were significant and <0.5, implying good construct validity. CONCLUSION: The Dutch and French translations of the HSPSC were found tobe valid and reliable for measuring patient safety culture in psychiatric hospitals. Our results also suggest the use of combinations of specific dimensions as recommended in previous research.

One fourth of unplanned transfers to a higher level of care are associated with a highly preventable adverse event: a patient record review in six Belgian hospitals.

OBJECTIVE: The objectives of this study are to determine the prevalence and preventability of adverse events requiring an unplanned higher level of care, defined as an unplanned transfer to the ICU or an in-hospital medical emergency team intervention, and to assess the type and the level of harm of each adverse event. DESIGN: A three-stage retrospective review process of screening, record review, and consensus judgment was performed. SETTING: Six Belgian acute hospitals. PATIENTS: During a 6-month period, all patients with an unplanned need for a higher level of care were selected. INTERVENTIONS: The records 6-month period, the records of all patients with an unplanned need for a higher level of care were assessed by a trained clinical team consisting of a research nurse, a physician, and a clinical pharmacist. MEASUREMENTS AND MAIN RESULTS: Adverse events were found in 465 of the 830 reviewed patient records (56%). Of these, 215 (46%) were highly preventable. The overall incidence rate of patients being transferred to a higher level of care involving an adverse event was 117.6 (95% CI, 106.9-128.3) per 100,000 patient days at risk, of which 54.4 (95% CI, 47.15-61.65) per 100,000 patient days at risk involving a highly preventable adverse event. This means that 25.9% of all unplanned transfers to a higher level of care were associated with a highly preventable adverse event. The adverse events were mainly associated with drug therapy (25.6%), surgery (23.7%), diagnosis (12.4%), and system issues (12.4%). The level of harm varied from temporary harm (55.7%) to long-term or permanent impairment (19.1%) and death (25.2%). Although the direct causality is often hard to prove, it is reasonable to consider these adverse events as a contributing factor. CONCLUSION: Adverse events were found in 56% of the reviewed records, of which almost half were considered highly preventable. This means that one fourth of all unplanned transfers to a higher level of care were associated with a highly preventable adverse event.

Variability of patient safety culture in Belgian acute hospitals.

OBJECTIVES: The aim of this study was to measure differences in safety culture perceptions within Belgian acute hospitals and to examine variability based on language, work area, staff position, and work experience. METHODS: The Hospital Survey on Patient Safety Culture was distributed to hospitals participating in the national quality and safety program (2007-2009). Hospitals were invited to participate in a comparative study. Data of 47,136 respondents from 89 acute hospitals were used for quantitative analysis. Percentages of positive response were calculated on 12 dimensions. Generalized estimating equations models were fitted to explore differences in safety culture. RESULTS: Handoffs and transitions, staffing, and management support for patient safety were considered as major problem areas. Dutch-speaking hospitals had higher odds of positive perceptions for most dimensions in comparison with French-speaking hospitals. Safety culture scores were more positive for respondents working in pediatrics, psychiatry, and rehabilitation compared with the emergency department, operating theater, and multiple hospital units. We found an important gap in safety culture perceptions between leaders and assistants within disciplines. Administration and middle management had lower perceptions toward patient safety. Respondents working less than 1 year in the current hospital had more positive safety culture perceptions in comparison with all other respondents. CONCLUSIONS: Large comparative databases provide the opportunity to identify distinct high and low scoring groups. In our study, language, work area, and profession were identified as important safety culture predictors. Years of experience in the hospital had only a small effect on safety culture perceptions.

Implementing an electronic medication overview in Belgium.

BACKGROUND: An accurate medication overview is essential to reduce medication errors. Therefore, it is essential to keep the medication overview up-to-date and to exchange healthcare information between healthcare professionals and patients. Digitally shared information yields possibilities to improve communication. However, implementing a digitally shared medication overview is challenging. This articles describes the development process of a secured, electronic platform designed for exchanging medication information as executed in a pilot study in Belgium, called "Vitalink". FINDINGS: The goal of "Vitalink" is to improve the exchange of medication information between professionals working in healthcare and patients in order to achieve a more efficient cooperation and better quality of care. Healthcare professionals of primary and secondary health care and patients of four Belgian regions participated in the project. In each region project groups coordinated implementation and reported back to the steering committee supervising the pilot study. The electronic medication overview was developed based on consensus in the project groups. The steering committee agreed to establish secured and authorized access through the use of electronic identity documents (eID) and a secured, eHealth-platform conform prior governmental regulations regarding privacy and security of healthcare information. DISCUSSION: A successful implementation of an electronic medication overview strongly depends on the accessibility and usability of the tool for healthcare professionals. Coordinating teams of the project groups concluded, based on their own observations and on problems reported to them, that secured and quick access to medical data needed to be pursued. According to their observations, the identification process using the eHealth platform, crucial to ensure secured data, was very time consuming. Secondly, software packages should meet the needs of their users, thus be adapted to daily activities of healthcare professionals. Moreover, software should be easy to install and run properly. The project would have benefited from a cost analysis executed by the national bodies prior to implementation.

Comparing the effectiveness of two cardiovascular prevention programmes for highly educated professionals in general practice: a randomised clinical trial.

BACKGROUND: Cardiovascular disease is a major cause of mortality and morbidity and its prevalence is set to increase. While the benefits of medical and lifestyle interventions are established, the effectiveness of interventions which seek to improve the way preventive care is delivered in general practice is less so. The aim was to study and to compare the effectiveness of 2 intervention programmes for reducing cardiovascular risk factors within general practice. METHODS: A randomised controlled trial was conducted in Belgium between 2007-2010 with 314 highly educated and mainly healthy professionals allocated to a medical (MP) or a medical + lifestyle (MLP) programme. The MP consisted of medical assessments (screening and follow-up) and the MLP added a tailored lifestyle change programme (web-based and individual coaching) to the MP. Primary outcomes were total cholesterol, blood pressure, and body mass index (BMI). The secondary outcomes were smoking status, fitness-score, and total cardiovascular risk. RESULTS: The mean age was 41 years, 95 (32%) participants were female, 7 had a personal cardiovascular event in their medical history and 3 had diabetes. There were no significant differences found between MP and MLP in primary or secondary outcomes. In both study conditions decreases of cholesterol, systolic blood pressure, and diastolic blood pressure were found. Unfavourable increases were found for BMI (p < .05). A significant decrease of the overall cardiovascular risk was reported (p < .001). CONCLUSIONS: Both interventions are effective in reducing cardiovascular risk. In our population the combined medical and lifestyle programme was not superior to the medical programme. TRIAL REGISTRATION: ISRCTN23940498.

Prevalence of atrial fibrillation in adults participating in a large-scale voluntary screening programme in Belgium.

OBJECTIVE: Atrial fibrillation (AF) is a common arrhythmia in clinical practice. AF fulfils many of the criteria for a screening programme. No data about the prevalence of AF in non-hospitalized patients are available in Belgium. The aim of the study was to assess feasibility and effectiveness of a nationwide-organized voluntary screening programme in the general population in Belgium. METHODS: A total of 13.564 participants were screened, of whom 10,758 were older than 40 years (GSP group). Participants filled in stroke risk stratification questionnaires (CHADS2 and CHA2DS2-VASc). A one-lead electrocardiogram was performed. RESULTS: 228 participants had AF at the time of screening (AF group), with 125 women and 103 men (i.e., 1.9% and 2.6% of total women and men), representing a prevalence of 2.2% (95% CI 1.3% and 3.0%) of the screened population. Age of the AF group was 67 +/- 12 y (range 40-87 y). Using the CHADS2-score, 58% of participants with a positive AF screening had a high risk score, and 21% had an intermediate risk score. Using the CHA2DS2-VASc-score, 72% of the participants had a high risk score, and 21% had an intermediate risk score. CONCLUSION: AF was present in 2.2% of the respondents. At least 60% of AF group had an increased risk for thrombo-embolism. Although substantial methodological issues limit the exact interpretation of these results, the present study shows that a volunatry screening programme with a simple screening protocol is able to detect an important number of patients with previously undetected AF.

Design of a medical record review study on the incidence and preventability of adverse events requiring a higher level of care in Belgian hospitals.

BACKGROUND: Adverse events are unintended patient injuries that arise from healthcare management resulting in disability, prolonged hospital stay or death. Adverse events that require intensive care admission imply a considerable financial burden to the healthcare system. The epidemiology of adverse events in Belgian hospitals has never been assessed systematically. FINDINGS: A multistage retrospective review study of patients requiring a transfer to a higher level of care will be conducted in six hospitals in the province of Limburg. Patient records are reviewed starting from January 2012 by a clinical team consisting of a research nurse, a physician and a clinical pharmacist. Besides the incidence and the level of causation and preventability, also the type of adverse events and their consequences (patient harm, mortality and length of stay) will be assessed. Moreover, the adequacy of the patient records and quality/usefulness of the method of medical record review will be evaluated. DISCUSSION: This paper describes the rationale for a retrospective review study of adverse events that necessitate a higher level of care. More specifically, we are particularly interested in increasing our understanding in the preventability and root causes of these events in order to implement improvement strategies. Attention is paid to the strengths and limitations of the study design.

A nationwide hospital survey on patient safety culture in Belgian hospitals: setting priorities at the launch of a 5-year patient safety plan.

OBJECTIVE: To measure patient safety culture in Belgian hospitals and to examine the homogeneous grouping of underlying safety culture dimensions. METHODS: The Hospital Survey on Patient Safety Culture was distributed organisation-wide in 180 Belgian hospitals participating in the federal program on quality and safety between 2007 and 2009. Participating hospitals were invited to submit their data to a comparative database. Homogeneous groups of underlying safety culture dimensions were sought by hierarchical cluster analysis. RESULTS: 90 acute, 42 psychiatric and 11 long-term care hospitals submitted their data for comparison to other hospitals. The benchmark database included 55 225 completed questionnaires (53.7% response rate). Overall dimensional scores were low, although scores were found to be higher for psychiatric and long-term care hospitals than for acute hospitals. The overall perception of patient safety was lower in French-speaking hospitals. Hierarchical clustering of dimensions resulted in two distinct clusters. Cluster I grouped supervisor/manager expectations and actions promoting safety, organisational learning-continuous improvement, teamwork within units and communication openness, while Cluster II included feedback and communication about error, overall perceptions of patient safety, non-punitive response to error, frequency of events reported, teamwork across units, handoffs and transitions, staffing and management support for patient safety. CONCLUSION: The nationwide safety culture assessment confirms the need for a long-term national initiative to improve patient safety culture and provides each hospital with a baseline patient safety culture profile to direct an intervention plan. The identification of clusters of safety culture dimensions indicates the need for a different approach and context towards the implementation of interventions aimed at improving the safety culture. Certain clusters require unit level improvements, whereas others demand a hospital-wide policy.

Interpretation and management of INR results: a case history based survey in 13 countries.

INTRODUCTION: Standardisation of treatment with vitamin K antagonists (VKAs) is still an issue after 60 years of use. The study aimed to explore aspects of VKA monitoring in primary and secondary care. METHODS: Two case histories were distributed to physicians in 13 countries. Case history A focused on a patient with atrial fibrillation on stable anticoagulation (latest INR 2.3). Physicians were asked about frequency of INR measurement, when to change the VKA dose, and the patient's annual risk of ischemic stroke and bleeding. Case history B focused on a patient with an unexpected INR of 4.8, asking for the patient's 48-hour bleeding risk, the immediate dose reduction and time until a repeat INR. RESULTS: Altogether, 3016 physicians responded (response rate 8 - 38%), of which 82% were from primary care and 18% from secondary care. Answers varied substantially within and between countries regardless of level of care and VKA used. Median number of weeks between INR measurements was 4 - 6 weeks. Median threshold INR for increasing or decreasing the VKA dose was 1.9 and 3.1, respectively. Risk of ischemic stroke and bleeding were overestimated 2 - 3 times. In case history B, the median dose reduction the two first days was 75% for GPs and 55% for specialists, irrespective of estimates of bleeding risk; with one week to a repeat INR. CONCLUSION: Variation in VKA monitoring is substantial implying clinical consequences. Guidelines seem either unknown or may be considered impracticable. Further efforts towards standardisation of VKA management are needed.
