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.

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.

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.

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.

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.

Are fixed-rate step tests medically safe for assessing physical fitness?

Maximal oxygen uptake (VO(2max)) can be predicted by fixed-rate step tests. However, it remains to be analyzed as to what exercise intensities are reached during such tests to address medical safety. In this study, we compared the physiological response to a standardized fixed-rate step test with maximal cardiopulmonary exercise testing (CPET). One hundred and thirteen healthy adults executed a maximal CPET on bike, followed by a standardized fixed-rate step test 1 week later. During these tests, heart rate (HR) and VO(2) were monitored continuously. From the maximal CPET, the ventilatory threshold (VT) was calculated. Next, the physiological response between maximal CPET and step testing was compared. The step test intensity was 85 ± 24% CPET VO(2max) and 88 ± 11% CPET HR(max) (VO(2max) and HR(max) were significantly different between CPET and step testing; p < 0.01). In 41% of the subjects, step test exercise intensities >95% CPET VO(2max) were noted. A greater step testing exercise intensity (%CPET VO(2max)) was independently related to higher body mass index, and lower body height, exercise capacity (p < 0.05). Standardized fixed-rate step tests elicit vigorous exercise intensities, especially in small, obese, and/or physically deconditioned subjects. Medical supervision might therefore be required during these tests.

Testing an integrated model of the theory of planned behaviour and self-determination theory for different energy balance-related behaviours and intervention intensities.

OBJECTIVES: The aim of the study was to test the relations between constructs from the self-determination theory (autonomous and controlled motivation), the theory of planned behaviour (attitudes, self-efficacy, and intentions), and behaviour change within a theoretically integrated model. Additionally, the aim was to test if these relations vary by behaviour (physical activity or dietary behaviour) or intervention intensity (frequency). DESIGN: It was a randomized controlled trial with a 'usual care' condition (medical screening only) and an intervention condition (medical screening+access to a website and coaching). Participants in the latter condition could freely determine their own intervention intensity. METHODS: Participants (N= 287) completed measures of the theoretical constructs and behaviour at baseline and after the first intervention year (N= 236). Partial least squares path modelling was used. RESULTS: Changes in autonomous motivation positively predicted changes in self-efficacy and intentions towards a healthy diet. Changes in controlled motivation positively predicted changes in attitudes towards physical activity, changes in self-efficacy, and changes in behavioural intentions. The intervention intensity moderated the effect of self-efficacy on intentions towards physical activity and the relationship between attitude and physical activity. Changes in physical activity were positively predicted by changes in intentions whereas desired changes in fat intake were negatively predicted by the intervention intensity. CONCLUSIONS: Important relations within the theoretically integrated model were confirmed but others were not. Moderation effects were found for behaviour and intervention intensity.

Willingness to pay for a cardiovascular prevention program in highly educated adults: a randomized controlled trial.

OBJECTIVES: The aim of this study was to determine adults' Willingness To Pay (WTP) for CardioVascular Disease (CVD) intervention programs of different intensities. METHODS: Three hundred fourteen participants were randomized to two study conditions: (i) CVD risk assessment/communication; (ii) CVD risk assessment/communication + a behavior change program. The behavior change program was aimed at increasing physical activity, reducing saturated fat intake and smoking cessation. It consisted of a tailored Web site and individual coaching with a self-selected dose. At post-assessment, WTP and perceived autonomy support items were included. The intervention dose was registered throughout the trial and post-hoc intervention dose groups were created. Pearson Chi-Square tests, Student's t-tests, one-way analyses of variance were used to examine WTP-differences between the study conditions and intervention dose groups. RESULTS: Twenty-four months after baseline, 61 and 135 participants of the control and intervention condition, respectively, completed the questionnaires. No WTP difference was found between the study conditions. However, participants that selected a higher intervention dose were willing to pay significantly more for their program (p < .05). CONCLUSIONS: In general, people want to pay the same amount of money for a CVD prevention program, irrespective of the inclusion of a behavior change program. However, there seems to be an association between the self-selected dose of the latter program and the WTP.

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.

Cost-utility of a cardiovascular prevention program in highly educated adults: intermediate results of a randomized controlled trial.

OBJECTIVES: Little is known about the costs and the effects of cardiovascular prevention programs targeted at medical and behavioral risk factors. The aim was to evaluate the cost-utility of a cardiovascular prevention program in a general sample of highly educated adults after 1 year of intervention. METHODS: The participants were randomly assigned to intervention (n = 208) and usual care conditions (n = 106). The intervention consisted of medical interventions and optional behavior-change interventions (e.g., a tailored Web site). Cost data were registered from a healthcare perspective, and questionnaires were used to determine effectiveness (e.g., quality-adjusted life-years [QALYs]). A cost-utility analysis and sensitivity analyses using bootstrapping were performed on the intermediate results. RESULTS: When adjusting for baseline utility differences, the incremental cost was 433 euros and the incremental effectiveness was 0.016 QALYs. The incremental cost-effectiveness ratio was 26,910 euros per QALY. CONCLUSIONS: The intervention was cost-effective compared with usual care in this sample of highly educated adults after 1 year of intervention. Increased participation would make this intervention highly cost-effective.

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.

Impact of heart failure on hospital activity and healthcare costs in Belgium.

Heart failure (HF) is a serious public health problem worldwide. It has a high prevalence, affects mainly the elderly and causes high mortality or disability with high economic costs. The aim of the present study was to calculate the number of admissions for HF, the total in-hospital stay, the mean length of in-hospital stay and the in-hospital costs due to HF in Belgium. Retrospective analysis of data from the national hospital registration system provided the following results. In 2001, there were 19,398 admissions with HF as a primary diagnosis, with a total in-hospital stay of 286,938 days. The mean in-hospital stay for HF was 14.8 days. The total in-hospital cost of HF as a primary diagnosis was euro 94,113,827, representing 1.8% of the total hospital expenditure. The limitations of this study are its mere focus on admissions and their characteristics in 2001, and the use of a retrospective analysis. Nevertheless, it led to the conclusion that HF was responsible for a significant number of in-hospital days, with a significant impact on healthcare costs in Belgium.

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.

The PreCardio-study protocol--a randomized clinical trial of a multidisciplinary electronic cardiovascular prevention programme.

BACKGROUND: Cardiovascular diseases (CVD) are the leading cause of death and the third cause of disability in Europe. Prevention programmes should include interventions aimed at a reduction of medical risk factors (hypertension, hypercholesterol, hyperglycemia, overweight and obesity) as well as behavioural risk factors (sedentary lifestyle, high fat intake and low fruit and vegetable intake, smoking). The aim of this study is to investigate the effects of a multifaceted, multidisciplinary electronic prevention programme on cardiovascular risk factors. METHODS/DESIGN: In a randomized controlled trial, one group will receive a maximal intervention (= intervention group). The intervention group will be compared to the control group receiving a minimal intervention. An inclusion of 350 patients in total, with a follow-up of 3 years is foreseen. The inclusion criteria are age between 25-65 and insured by the Onderlinge Ziekenkas, insuring for guaranteed income in case of illness for self-employed. The maximal intervention group receives several prevention consultations by their general practitioner (GP) using a new type of cardiovascular risk calculator with personalized feedback on behavioural risk factors. These patients receive a follow-up with intensive support of health behaviour change via different methods, i.e. a tailored website and personal advice of a multidisciplinary team (psychologist, physiotherapist and dietician). The aim of this strategy is to reduce cardiovascular risk factors according to the guidelines. The primary outcome measures will be cardiovascular risk factors. The secondary outcome measures are cardiovascular events, quality of life, costs and incremental cost effectiveness ratios. The control group receives prevention consultations using a new type of cardiovascular risk calculator and general feedback. DISCUSSION: This trial incorporates interventions by GPs and other health professionals aiming at a reduction of medical and behavioural cardiovascular risk factors. An assessment of clinical, psychological and economical outcome measures will be performed.

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.

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.
