Clinical decision support improves the appropriateness of laboratory test ordering in primary care without increasing diagnostic error: the ELMO cluster randomized trial.

BACKGROUND: Inappropriate laboratory test ordering poses an important burden for healthcare. Clinical decision support systems (CDSS) have been cited as promising tools to improve laboratory test ordering behavior. The objectives of this study were to evaluate the effects of an intervention that integrated a clinical decision support service into a computerized physician order entry (CPOE) on the appropriateness and volume of laboratory test ordering, and on diagnostic error in primary care. METHODS: This study was a pragmatic, cluster randomized, open-label, controlled clinical trial. SETTING: Two hundred eighty general practitioners (GPs) from 72 primary care practices in Belgium. PATIENTS: Patients aged ≥ 18 years with a laboratory test order for at least one of 17 indications: cardiovascular disease management, hypertension, check-up, chronic kidney disease (CKD), thyroid disease, type 2 diabetes mellitus, fatigue, anemia, liver disease, gout, suspicion of acute coronary syndrome (ACS), suspicion of lung embolism, rheumatoid arthritis, sexually transmitted infections (STI), acute diarrhea, chronic diarrhea, and follow-up of medication. INTERVENTIONS: The CDSS was integrated into a computerized physician order entry (CPOE) in the form of evidence-based order sets that suggested appropriate tests based on the indication provided by the general physician. MEASUREMENTS: The primary outcome of the ELMO study was the proportion of appropriate tests over the total number of ordered tests and inappropriately not-requested tests. Secondary outcomes of the ELMO study included diagnostic error, test volume, and cascade activities. RESULTS: CDSS increased the proportion of appropriate tests by 0.21 (95% CI 0.16-0.26, p < 0.0001) for all tests included in the study. GPs in the CDSS arm ordered 7 (7.15 (95% CI 3.37-10.93, p = 0.0002)) tests fewer per panel. CDSS did not increase diagnostic error. The absolute difference in proportions was a decrease of 0.66% (95% CI 1.4% decrease-0.05% increase) in possible diagnostic error. CONCLUSIONS: A CDSS in the form of order sets, integrated within the CPOE improved appropriateness and decreased volume of laboratory test ordering without increasing diagnostic error.

Initiation of advance care planning in newly admitted nursing home residents in Flanders, Belgium: A prospective cohort study.

AIM: To describe (i) the timing of initiation of advance care planning (ACP) after nursing home admission; (ii) the association of dementia and physical health with ACP initiation; and (iii) if and how analgesic use and use of lipid modifying agents is related to ACP, in a cohort of newly admitted residents. METHODS: A prospective, observational cohort study of nursing home residents was carried out. Data were collected 3 months, 15 months (year 1) and 27 months (year 2) after admission, using a structured questionnaire and validated measuring tools. RESULTS: ACP was never initiated during the 2-year stay for 38% of the residents, for 22% ACP was initiated at admission, for 21% during year 1 and for 19% during year 2 (n = 323). ACP initiation was strongly associated with dementia, but not with physical health. Residents without dementia were more likely to have ACP initiation at admission or not at all, whereas ACP initiation was postponed for residents with dementia. Between admission and year 2, analgesic use increased (from 34% to 42%), and the use of lipid-modifying agents decreased (from 28% to 21%). Analgesic use increased more in residents with ACP initiation during year 1 and year 2. The use of lipid-modifying agents was not associated with ACP. CONCLUSIONS: The timing of ACP initiation differed significantly for residents with and without dementia, which highlights the importance of an early onset of ACP before residents lose their decision-making capacity. ACP conversations might create opportunities to discuss adequate pain and other symptom treatment, and deprescribing at the end of life. Geriatr Gerontol Int 2019; 19: 141-146.

Discontinuation of Long-Term Antipsychotic Drug Use for Behavioral and Psychological Symptoms in Older Adults Aged 65 Years and Older With Dementia.

BACKGROUND: Antipsychotic drugs are often used to treat behavioral and psychological symptoms (BPSD) in adults aged 65 years and older with dementia, although there is uncertainty about the effectiveness of long-term use for this indication and there are concerns that they may cause harm. OBJECTIVES: To evaluate whether discontinuation of long-term antipsychotic drugs for BPSD is successful in adults aged 65 years and older with dementia. This article is based on a Cochrane review updated in 2018. DESIGN: A Cochrane systematic review and meta-analysis. SETTING AND PARTICIPANTS: Eight databases were searched in January 2018 to identify 10 randomized controlled trials with 632 older adults. MEASURES: We used standard methodological procedures according to the Cochrane Handbook for Systematic Reviews of Interventions. We assessed the number of patients completing the study. We considered sustained withdrawal of antipsychotics until the end of the study period as successful outcome. RESULTS: Based on assessment of 7 studies (n = 446), discontinuation may make little or no difference to whether or not participants complete the study (low-quality evidence). In 2 trials, including participants with psychosis, agitation, or aggression who had responded to antipsychotic treatment, discontinuation of antipsychotics was associated with a higher risk of leaving the study prematurely because of symptomatic relapse or a shorter time to symptomatic relapse. We found low-quality evidence from 7 trials (n = 519) that discontinuation may make little or no difference to overall BPSD, measured using various scales. There was some evidence from subgroup analyses in 2 trials that discontinuation may be associated with a worsening of BPSD in participants with more severe BPSD at baseline. CONCLUSIONS: Our meta-analysis revealed that there is low-quality evidence that long-term antipsychotic drugs for BPSD may be successfully discontinued in most adults aged 65 and older.

Medication use in a cohort of newly admitted nursing home residents (Ageing@NH) in relation to evolving physical and mental health.

BACKGROUND: Medication use is high among nursing home (NH) residents, but there is a lack of longitudinal studies, determining medication use at admission and its evolution over time. AIM: Describing the evolution of the medication use two years after entering a NH, compared to the baseline observations and exploring the relation to the physical and mental health. METHODS: Data from the observational prospective Ageing@NH study, based on an inception cohort of newly admitted residents at NHs (65+) was used, selecting those consenting and with medication chart available. Information about socio-demographic, functional and mental characteristics, as well as medication use, was collected at baseline, year 1 and year 2. RESULTS: Medication chart was available for n = 741 at baseline (mean age 83.8, 66% female), and for n = 342 residents in year 2. The mean number of total medications increased from 8.9 to 10.1 (p-value < 0.001). Polypharmacy was high, with an increase in extreme polypharmacy from 23% to 32%. The biggest increase was noted in the respiratory (from 17% to 27%) and alimentary medications (from 80% to 87%). Cardiovascular medication use in year 2, was lower in those with stable high dependency (77%) and those evolving from low to high dependency (79%), than those with stable low dependency (89%) (p < 0.025). For residents with or evolving to dementia symptoms, decline in most medication groups was observed, especially in pain and sleeping medications, while antipsychotics use increased. CONCLUSION: Although medication use was high, signs of deprescribing were noted when the physical and mental health of the residents declined.

The family physician's perceived role in preventing and guiding hospital admissions at the end of life: a focus group study.

PURPOSE: Family physicians play a pivotal role in providing end-of-life care and in enabling terminally ill patients to die in familiar surroundings. The purpose of this study was to explore the family physicians' perceptions of their role and the difficulties they have in preventing and guiding hospital admissions at the end of life. METHODS: Five focus groups were held with family physicians (N= 39) in Belgium. Discussions were transcribed verbatim and analyzed using a constant comparative approach. RESULTS: Five key roles in preventing and guiding hospital admissions at the end of life were identified: as a care planner, anticipating future scenarios; as an initiator of decisions in acute situations, mostly in an advisory manner; as a provider of end-of-life care, in which competency and attitude is considered important; as a provider of support, particularly by being available during acute situations; and as a decision maker, taking overall responsibility. CONCLUSIONS: Family physicians face many different and complex roles and difficulties in preventing and guiding hospital admissions at the end of life. Enhancing the family physician's role as a gatekeeper to hospital services, offering the physicians more end-of-life care training, and developing or expanding initiatives to support them could contribute to a lower proportion of hospital admissions at the end of life.

Review of guidelines on primary prevention of cardiovascular disease with aspirin: how much evidence is needed to turn a tanker?

AIMS: There are numerous national and international guidelines on the use of aspirin for the primary prevention of cardiovascular disease. Given the uncertainties about aspirin in primary prevention, our aim was to compare the recommendations and the reported evidence in guidelines for the treatment with aspirin of subjects free of cardiovascular disease with or without diabetes. METHODS AND RESULTS: Guidelines were retrieved through Medline and other electronic databases and through a web-based search for guideline development organizations. The content of the recommendations and the underlying evidence were analysed with qualitative and bibliometric methods. In addition, we searched for recent studies to assess whether they underscore the current recommendations. We included 12 guidelines: six European, three North American, and one each from New Zealand, Australia, and the World Health Organization. Recommendations differ with regard to outcome (morbidity, mortality), time span (years of risk), cut-off percentage between high and low risk, and the dose of aspirin. Most guidelines are not in line with recent evidence, which show that aspirin is of uncertain net value as the reduction in absolute risk for occlusive CV events needs to be weighed against an increase in the risk of major bleeds. CONCLUSION: We found conflicting recommendations in various guidelines about the use of aspirin for the primary prevention of cardiovascular events, which reflect differences in selection of the evidence and in the timing of publication. According to recent evidence, in general, the use of aspirin seems no longer justifiable in primary prevention in patients with or without diabetes.

Advance care planning and dying in nursing homes in Flanders, Belgium: a nationwide survey.

CONTEXT: In Belgium, data on actual advance care planning (ACP) in nursing homes (NHs) are scarce. OBJECTIVES: To investigate the prevalence and characteristics of documented advance directives and physicians' orders for end-of-life care in NHs, and the authorization of a legal representative in relation to the residents' demographic and clinical characteristics and care received. METHODS: This was a retrospective cross-sectional study, including all NH residents deceased during September and October 2006 in all 594 NHs in Flanders, Belgium. Structured mail questionnaires about the resident's characteristics, hospital transfers, palliative care delivery, ACPs, and authorization of legal representatives were completed via the NH administrators and nurses involved in the care of the resident. RESULTS: Administrators of 318 NHs (53.5%) reported 1303 deaths. Nurses provided information about 1240 (95.2%) of these deaths. At the end of life, NH residents often had dementia (65.2%) and were severely dependent (76.1%). Almost half (43.1%) had at least one hospital transfer during the last three months of life and two-thirds received palliative care. Half had an ACP, predominantly a physician's order and less often an advance directive. Having advance directives or physician's orders was associated with receiving palliative care. Residents with a physician's order more often died in the NH. Nine percent had an authorized legal representative. CONCLUSION: Prevalence of ACPs and formal authorization of a legal representative was low among the deceased NH residents in Flanders, Belgium. There was a higher prevalence of physicians' orders, often established after the resident had lost capacity. Initiatives should be developed to stimulate more advance discussion on care options and making end-of-life decision with the residents while they retain capacity.

Health Alliance for prudent antibiotic prescribing in patients with respiratory tract infections (HAPPY AUDIT) -impact of a non-randomised multifaceted intervention programme.

BACKGROUND: Excessive use of antibiotics is worldwide the most important reason for development of antimicrobial resistance. As antibiotic resistance may spread across borders, high prevalence countries may serve as a source of bacterial resistance for countries with a low prevalence. Therefore, bacterial resistance is an important issue with a potential serious impact on all countries. Initiatives have been taken to improve the quality of antibiotic prescribing in primary care, but only few studies have been designed to determine the effectiveness of multifaceted strategies across countries with different practice setting. The aim of this study was to evaluate the impact of a multifaceted intervention targeting general practitioners (GPs) and patients in six countries with different health organization and different prevalence of antibiotic resistance. METHODS: GPs from two Nordic countries, two Baltic Countries and two Hispano-American countries registered patients with respiratory tract infections (RTIs) in 2008 and 2009. After first registration they received individual prescriber feedback and they were offered an intervention programme that included training courses, clinical guidelines, posters for waiting rooms, patient brochures and access to point of care tests (Strep A and C-Reactive Protein). Antibiotic prescribing rates were compared before and after the intervention. RESULTS: A total of 440 GPs registered 47011 consultations; 24436 before the intervention (2008) and 22575 after the intervention (2009). After the intervention, the GPs significantly reduced the percentage of consultations resulting in an antibiotic prescription. In patients with lower RTI the GPs in Lithuania reduced the prescribing rate by 42%, in Russia by 25%, in Spain by 25%, and in Argentina by 9%. In patients with upper RTIs, the corresponding reductions in the antibiotic prescribing rates were in Lithania 20%, in Russia 15%, in Spain 9%, and in Argentina 5%. CONCLUSION: A multifaceted intervention programme targeting GPs and patients and focusing on improving diagnostic procedures in patients with RTIs may lead to a marked reduction in antibiotic prescribing. The pragmatic before-after design used may suffer from some limitations and the reduction in antibiotic prescribing could be influenced by factors not related to the intervention.

Current and projected prevalence of arterial hypertension in sub-Saharan Africa by sex, age and habitat: an estimate from population studies.

INTRODUCTION: In sub-Saharan Africa (SSA), data on hypertension prevalence in terms of urban or rural and sex difference are lacking, heterogeneous or contradictory. In addition, there are no accurate estimates of hypertension burden. OBJECTIVE: To estimate the age-specific and sex-specific prevalence of arterial hypertension in SSA in urban and rural adult populations. METHODS: We searched for population studies, conducted from 1998 through 2008 in SSA. We extracted data from selected studies on available prevalences and used a logistic regression model to estimate all age/sex/habitat (urban/rural)/country-specific prevalences for SSA up to 2008 and 2025. On the basis of the United Nations Population Fund data for 2008 and predictions for 2025, we estimated the number of hypertensives in both years. RESULTS: Seventeen studies pertaining to 11 countries were analysed. The overall prevalence rate of hypertension in SSA for 2008 was estimated at 16.2% [95% confidence interval (CI) 14.1-20.3], ranging from 10.6% in Ethiopia to 26.9% in Ghana. The estimated prevalence was 13.7% in rural areas, 20.7% in urban areas, 16.8% in males, and 15.7% in women. The total number of hypertensives in SSA was estimated at 75 million (95% CI 65-93 million) in 2008 and at 125.5 million (95% CI 111.0-162.9 million) by 2025. CONCLUSION: The estimated number of hypertensives in 2008 is nearly four times higher than the last (2005) estimate of the World Health Organization Regional Office for Africa. Prevalences were significantly higher in urban than in rural populations. Population data are lacking in many countries underlining the need for national surveys.

Assessment of antipsychotic prescribing in Belgian nursing homes.

BACKGROUND: Given the potential adverse effects of antipsychotics, high use in nursing homes creates concern. Our study goal was to explore the use of antipsychotics in relation to resident characteristics, and to assess the appropriateness of antipsychotic prescribing in Belgian nursing homes. METHODS: Data were used from a cross-sectional study (Prescribing in Homes for the Elderly; PHEBE) conducted in 76 nursing homes in Belgium. Antipsychotics were classified into typical and atypical, using the anatomical therapeutic and chemical classification. Ten inappropriate antipsychotic prescribing indicators were selected from the updated Beers criteria (2003), Bergen District Nursing Home Study (BEDNURS) indicators, and Screening Tool of Older People's Prescriptions criteria (STOPP). RESULTS: The residents' mean age was 84.8 years, 78.1% of whom were female. The prevalence of antipsychotic utilization was 32.9%. Antipsychotics were mainly indicated for dementia-related agitation, and psychosis with/without dementia. Higher use of antipsychotics was found for dementia (OR: 3.27; 95% CI: 2.61-4.09), insomnia (OR: 1.38; 95% CI: 1.10-1.73), depression (OR: 1.30; 95% CI: 1.03-1.65), and age <80 years (OR: 1.79; 95% CI: 1.38-2.33). Inappropriate antipsychotic prescribing indicators scoring the highest among users were: long-term use (92.6%), use despite risk of falling (45.6%), combined use with other psychotropics (31.8%), and duplicate use (15.1%). Inappropriate prescribing was associated with depression (OR: 3.41) and insomnia (OR: 2.17). CONCLUSION: The indicator-driven analysis of antipsychotic prescribing quality revealed a need for improvement, with the main prescribing problems relating to duration and combination of therapies. Risks/benefits of off-label use need to be evaluated more consciously at the start of therapy, and at periodic re-evaluations.

Preferences of patients with advanced lung cancer regarding the involvement of family and others in medical decision-making.

OBJECTIVE: To explore the preferences of competent patients with advanced lung cancer regarding involvement of family and/or others in their medical decision-making, and their future preferences in case of loss of competence. METHODS: Over 1 year, physicians in 13 hospitals in Flanders, Belgium, recruited patients with initial non-small­cell lung cancer, stage IIIb or IV. The patients were interviewed with a structured questionnaire every 2 months until the fourth interview and every 4 months until the sixth interview. RESULTS: At inclusion, 128 patients were interviewed at least once; 13 were interviewed 6 consecutive times. Sixty-nine percent of patients wanted family members to be involved in medical decision-making and this percentage did not change significantly over time. One third of these patients did not achieve this preference. Ninety-four percent of patients wanted family involvement if they lost competence, 23% of these preferring primary physician control over decision-making, 41% shared physician and family control, and 36% primary family control. This degree of preferred family involvement expressed when competent did not change significantly over time at population level, but did at individual level; almost half the patients changed their minds either way at some point during the observation period. CONCLUSIONS: The majority of patients with lung cancer wanted family involvement in decision-making, and almost all did so in case of future loss of competence. However, as half of the patients changed their minds over time about the degree of family involvement they wanted if they lost competence, physicians should regularly rediscuss a patient's preferences.

Evaluation of medication adherence methods in the treatment of malaria in Rwandan infants.

OBJECTIVES: To compare three methods for evaluating treatment adherence in a 7-day controlled treatment period for malaria in children in Rwanda. METHODS: Fifty-six children (< 5 years) with malaria were recruited at the University Hospital of Butare, Rwanda. Patients were treated with quinine sulfate, taste-masked, pellets during seven days: three days in hospital (in-patient) followed by a four-day out-patient period. Three methods to evaluate medication adherence among patients were compared: manual pill count of returned tablets, patient self-report and electronic pill-box monitoring. These pill-boxes were equipped with a microchip registering date and time of every opening. Medication adherence was defined as the proportion of prescribed doses taken. The inter-dose intervals were analysed as well. RESULTS: Medication adherence data were available for 54 of the 56 patients. Manual pill count and patient self-report yielded a medication adherence of 100% for the in- and out-patient treatment periods. Based on electronic pill-box monitoring, medication adherence during the seven-day treatment period was 90.5 +/- 8.3%. Based on electronic pill-box monitoring inpatient medication adherence (99.3 +/- 2.7%) was markedly higher (p < 0.03) than out-patient adherence (82.7 +/- 14.7%), showing a clear difference between health workers' and consumers' medication adherence. CONCLUSION: Health workers' medication adherence was good. However, a significant lower medication adherence was observed for consumers' adherence in the outpatient setting. This was only detected by electronic pill-box monitoring. Therefore, this latter method is more accurate than the two other methods used in this study.

Nursing home policies regarding advance care planning in Flanders, Belgium.

BACKGROUND: The aim of this study is to discover how many nursing homes (NHs) in Flanders (Belgium) have policies on advance care planning (ACP) and their content regarding different medical end-of-life decisions. METHODS: A structured mail questionnaire was sent to the NH administrators of all 594 NHs in Flanders (Belgium) at the end of 2006. The questionnaire asked about the existence, timing of implementation and content of ACP policy documents (guidelines and patient-specific planning forms), and on NH characteristics related to end-of-life care. RESULTS: The response rate was 58.1%. The development of ACP policy documents began in 1989 with major increases in implementation taking place from 2000. In 2006, ACP policy documents were available in 95.1% of NHs. Most of these NHs had ACP guidelines as well as ACP patient-specific planning forms. Almost all patient-specific planning forms included anticipatory do-not-hospitalize (90.0%) and do-not-resuscitate decisions (83.2%). Anticipatory decisions about terminal sedation (29.2%) and euthanasia (19.7%) were mentioned less often and these decisions were not permitted to be made in all NHs. One out of three NHs had policies on the appointment of a patient's representative. CONCLUSION: By the end of 2006, almost all NHs in Flanders (Belgium) had an ACP policy. The implementation of ACP policies in Flemish NHs lagged behind other countries, but has developed rapidly since 2000. However, some NHs appear to ban some end-of-life options which are actually legal in Belgium. Further research is needed to investigate whether ACP policies have much impact on the quality of end-of-life care in NHs.

Preferences of advanced lung cancer patients for patient-centred information and decision-making: a prospective multicentre study in 13 hospitals in Belgium.

OBJECTIVE: To identify preferences of advanced lung cancer patients for receiving information and participating in decision-making concerning treatment options, health-care-setting transfers and end-of-life decision-making. METHODS: Over the course of 1 year, pulmonologists and oncologists in 13 hospitals in Flanders, Belgium, invited patients with an initial diagnosis of non-small-cell lung cancer IIIb/IV to participate in the study. Shortly after inclusion, the patients were interviewed with a structured questionnaire. RESULTS: One-hundred and twenty-eight patients with a median estimated survival time of 10 months participated. Almost all wanted information on diagnosis, treatment and cure rate and slightly fewer on life expectancy (88.2%). Information about palliative care was desired by 63.5% of patients and information about end-of-life decisions by 56.8%. The percentage of patients who preferred personal control over medical decision-making increased to 14.8% for treatment, 25.0% for transfer and 49.2% for end-of-life decisions, all of which were higher than for medical decisions in general (9.3%). CONCLUSION: Information and participation preferences of advanced lung cancer patients differ depending on the type of information or decision. PRACTICE IMPLICATIONS: As part of a patient-centred approach, physicians should not only check the general but also the specific information and participation preferences of their patients.

Prevalence of patients with do-not-resuscitate status on acute geriatric wards in Flanders, Belgium.

BACKGROUND: Elderly hospitalized patients have low survival rates after cardiopulmonary resuscitation, especially in the long term. This study aims to investigate the prevalence of patients with do-not-resuscitate (DNR) status on acute geriatric wards and the characteristics of the preceding decision-making process. METHODS: On all 94 geriatric wards in Flanders, Belgium (2002), the geriatrician who performed the bulk of clinical work was asked to fill in a retrospective structured mail questionnaire. RESULTS: The response rate was 72.3%. A DNR status was attributed to 20.3% of patients. A significant higher prevalence of patients with DNR status was found on wards with a geriatrician who had been active in patient care for 15 years or less and on wards with a DNR policy. Mostly, DNR status was attributed when the patient's condition declined (34.0%) or became critical (29.0%). Geriatricians consulted at least one person in 81.0% of the cases: (head) nurses in 72.2%, next of kin in 61.9%, the patient's general practitioner in 22.6%, and the patient him- or herself in 15.7%. Reasons stated to make a DNR decision were the prognosis (68.1%) and the physical condition of the patient (62.2%). Age was mentioned in only 21.1% of the cases, always in combination with other reasons. CONCLUSIONS: One fifth of patients on acute geriatric wards in Flanders have DNR status. The decision to attribute DNR status is most often made late in the course of the disease. (Head) nurses and the patient's next of kin are often consulted, the patient and his or her general practitioner rarely.

Physician-assisted death: attitudes and practices of community pharmacists in East Flanders, Belgium.

This study investigates attitudes and practices of community pharmacists with respect to physician-assisted death. Between 15 February and 15 April 2002, we sent anonymous mail questionnaires to 660 community pharmacists in the eastern province of Flanders, Belgium. The response rate was 54% (n = 359). Most of the pharmacists who responded felt that patients have the right to end their own life (73%), and that under certain conditions physicians may assist the patient in dying (euthanasia: 84%; physician-assisted suicide: 61%). Under the prevailing restrictive legislation, a quarter of the pharmacists were willing to dispense lethal drugs for euthanasia versus 86% if it were legalized, but only after being well informed by the physician. The respondents-favour guidelines for pharmacists drafted by their own professional organizations (95%), and enforced by legislation (90%) to ensure careful end-of-life practice. Over the last two years, 7.3% of the responding pharmacists have received a medical prescription for lethal drugs and 6.4% have actually dispensed them. So we can conclude that community pharmacists in East Flanders were not adverse to physician-assisted death, but their cooperation in dispensing lethal drugs was conditional on clinical information about the specific case and on protection by laws and professional guidelines.

Method to measure force required to remove Pediculus humanus capitis (Phthiraptera: Pediculidae) eggs from human hair.

Head lice are very common and mainly affect children between 3 and 12 yr old. Little is known about the way nits, the eggs of the head louse, are attached to the hair. In this report, an objective measurement procedure for the ease with which nits can be removed is presented. The first peak force, associated with the start of nit movement, and the average and maximal force during the sliding of the nit were measured. The three force variables correlated with the length of the cylinder by which the nit was attached to the hair. A negative correlation was found between the maximum force exerted and the distance of the nit from the scalp. The method described in this report can be used to determine the in vitro efficacy of various products to remove nits.

The incidence and characteristics of end-of-life decisions by GPs in Belgium.

BACKGROUND: Medical end-of-life decisions (ELDs) have been discussed for several years in different countries, but little is known about the involvement of GPs in these ELDs. OBJECTIVES: The aim of the present study was to establish the incidence and characteristics of ELDs by GPs. METHOD: We selected 3999 deaths, a 20% random sample of all registered deaths during the first 4 months of 1998 in Flanders, Belgium, and mailed anonymous questionnaires to the attesting physicians. Here we focus exclusively on the 1647 deaths certified by GPs. RESULTS: The GPs returned 1067 questionnaires (response rate of 64.8%). At least one ELD was made in 39.5% [95% confidence interval (CI) 37.8-41.2] of all primary care deaths. The incidence of euthanasia (including physician-assisted suicide) was 1.5% (95% CI 0.9-2.3) (incidence higher among more educated patients and at home), of administration of lethal drugs without the patient's explicit request 3.8% (95% CI 2.9-5.0) (higher among cancer patients), of alleviation of pain and symptoms with possibly life-shortening effect 18.6% (95% CI 17.0-20.2) (higher among cancer patients and married patients) and of non-treatment decisions 15.6% (95% CI 14.2-17.2) (higher among cancer patients and in nursing homes). The decision was not discussed with the patient in three out of four of the ELDs. A colleague was consulted in one in four ELD cases. CONCLUSION: ELDs are common in general practice in Flanders, Belgium, despite the restrictive law concerning euthanasia at the time of this study. The incidence of these ELDs varies with cause and place of death, the patient's education and the GP's religion and age. Requirements of prudent practice regarding ELDs are rather poorly met by GPs. Further international research and debate is needed to highlight the GPs' important role in end-of-life care.
