[show abstract][hide abstract] ABSTRACT: Our goal was to investigate the use of hypnosedatives (HSs) before and during hospitalization, explore the relationship between their use and various demographic and clinical variables, and compare the results with data from a similar 2000 study with particular interest in adherence to hospital formulary guidelines.
A cross-sectional observational survey of 326 hospitalized patients recruited from ten wards of the Ghent University Hospital, Gent, Belgium, with a patient interview and by evaluating medical and nursing files.
In 30.7% of patients, the use of a HS before admission was reported. According to the patient interview, 33.1% used a HS during hospitalization. However, according to medical and nursing files, use of HSs in the hospital was 10% higher (43.3%). In 19.4% of patients who took HSs before admission, their use was discontinued in the hospital. In 15.6% of patients who took no HS before admission, a HS was started in the hospital, according to the formulary guidelines (data from files). There was a positive correlation between HS use in the hospital and older age, longer hospitalization, not coming from home, higher number of HSs taken before hospitalization, sleeping problems emerging during hospitalization, and central nervous system (CNS) disorders. In comparison with 2000, we registered a slight decrease in HS use during hospitalization and a decrease in the number of newly started patients.
The prevalence of HS use in our university hospital is high, mostly as a result of continuation of HSs started before admission, as there seems to be no general policy of active cessation. Compared with the survey performed 10 years ago, fewer hospitalized patients are newly started on HSs, and when this is the case, the formulary guidelines are followed.

[show abstract][hide abstract] ABSTRACT: To investigate the frequency and type of drug related problems (DRPs) in geriatric patients (> 65 years), and to assess their contribution to hospital admission; to explore the appropriateness of drug therapy according to the Beers' criteria.
Cross-sectional observational survey of 110 elderly patients admitted during three non-consecutive months to the geriatric ward of a university hospital. Explorative assessment of appropriateness of drug therapy prior to hospital admission based on the Beers' criteria.
A DRP was the dominant reason for hospital admission in 14 out of the 110 patients (12.7%); for another 9 patients (8.2%), a DRP was partly contributing to hospital admission. For these 23 patients, adverse drug reactions and noncompliance were the most important types of DRPs. We found no relationship between drug related hospital admission and intake of a drug listed in the Beers criteria for inappropriate drug use in the elderly. Patients admitted for a DRP took more drugs before admission than patients admitted because of other reasons.
DRPs are an important cause for admission on the geriatric ward of our hospital. The drugs causing DRPs in this study were not those listed in the Beers list of inappropriate drugs in the elderly.

[show abstract][hide abstract] ABSTRACT: Intermittent claudication (IC) is pain caused by chronic occlusive arterial disease, that develops in a limb during exercise and is relieved with rest. Buflomedil is a vasoactive agent used to treat peripheral vascular disease. However, its clinical efficacy for IC has not yet been critically examined.
To evaluate the available evidence on the efficacy of buflomedil for IC.
We searched the specialized trials register of the Cochrane Peripheral Vascular Diseases Review Group (last searched November 2007), the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (Issue 4, 2007), MEDLINE (1966 to November 2007), International Pharmaceutical Abstracts (IPA) (from inception to November 2007), Science Citation Index (from inception to November 2007). We contacted Abbott Laboratories (buflomedil distributor) for controlled clinical trial data and approached authors for additional trial information.
Double-blinded, randomized controlled trials (RCTs) in patients with IC (Fontaine stage II) receiving oral buflomedil compared to placebo. Pain-free walking distance (PFWD) and maximum walking distance (MWD) were analysed by standardized exercise test.
Two authors independently assessed trial quality and extracted data. We contacted study authors for additional information.
We included two RCTS with 127 participants. Both RCTs showed moderate improvements in PFWD for patients on buflomedil. This improvement was statistically significant for both trials (WMD 75.1 m, 95% confidence interval (CI) 20.6 to 129.6; WMD 80.6 m, 95% CI 3.0 to 158.2), the latter being a wholly diabetic population. For both RCTs, MWD gains were statistically significant with wide confidence intervals (WMD 80.7 m, 95% CI 9.4 to 152; WMD 171.4 m, 95% CI 51.3 to 291.5), respectively.
There is little evidence available to evaluate the efficacy of buflomedil for IC. Most trials were excluded due to poor quality. The two included trials showed moderately positive results; these are undermined by publication bias since we know of at least another four unpublished, irretrievable, and inconclusive studies.Buflomedil's benefit is small in relation to safety issues and its narrow therapeutic range.
[show abstract][hide abstract] ABSTRACT: International research has proved that academic detailing positively influences the prescribing behaviour of physicians. In the North-East Flanders region of Belgium, a quantitative study of the feasibility and acceptability of academic detailing in general practice has demonstrated that academic detailers are appreciated by physicians.
In addition to the quantitative study, a qualitative study was carried out to determine physicians' attitudes to academic detailing and their objections against it.
This study took place in general practice in the North-East Flanders region of Belgium, using semistructured interviews. Nineteen physicians who had previously had a visit from an academic detailer in the quantitative study, and 19 who had refused were invited for an interview.
Eighteen physicians who had been visited by an academic detailer, and nine who had refused a visit agreed to be interviewed. Although most physicians who had had a visit from an academic detailer appreciated the visit, some barriers were revealed. Physicians had doubts about the objectivity, stated that the information was not new or that they had other ways to obtain information. These barriers were also mentioned by the physicians who had refused a visit. Additional barriers were that the visits were time-consuming, meant to cut expenses, politically coloured, and patronising.
Doubts about independence and objectivity of the information were stated as important barriers both by physicians who had accepted a visit from an academic detailer and by those who had not. These issues need to be dealt with when designing future interventions with academic detailers.

[show abstract][hide abstract] ABSTRACT: To investigate the feasibility and acceptability of academic detailing in general practice in the North-East-Flanders region of Belgium.
All local quality groups in the study region were randomly allocated to either (1) two academic detailing visits to the individual members or (2) two academic detailing visits during the meetings of the local quality group. During these visits, the results of a systematic review of the literature on non-steroidal anti-inflammatory agents (NSAIDs) were presented.
Of 14 local quality groups, 12 allocated to the individual intervention agreed to participate. Of the 184 physicians invited to receive an academic detailer, 142 had two visits on NSAIDs. One hundred and five physicians gave their opinion on the visits by means of a questionnaire. The great majority of the responders (90%) wished to receive an academic detailer on other topics in the future, with a frequency of two visits per year. Of 13 local quality groups, 12 allocated to the group intervention, with a total number of 192 physicians who agreed to participate. Ten local quality groups with 166 members received the information on NSAIDs. The actual attendance rate per intervention session was approximately two out of three physicians. All 166 physicians of the participating local quality groups were offered an evaluation form, and 79 responded. Of the responders who received the full group intervention, 88% wished to have more academic detailing visits on other topics in their local quality group. A comparison between the evaluation forms of the individual and the group intervention revealed no major differences concerning the acceptability of the intervention.
The pilot study showed that academic detailing is feasible in the North-East-Flanders region of Belgium. Both the individual visits and the visits to the local quality groups were rated positively, and a majority of the general practitioners who returned the evaluation questionnaire wished to receive such visits in the future. The structure of the local quality groups implies limitations to the practical organisation of a visit, but requires less time investment than individual visits.

[show abstract][hide abstract] ABSTRACT: To test a method for registration of adverse drug reactions (ADRs) resulting in hospital admission and of ADRs occurring during hospital stay. Spontaneous reporting was compared with data from patient interview.
Spontaneous reporting of ADRs by nurses and physicians, as well as patient interviews by pharmacists. This pilot project was carried out in the geriatric ward of the Ghent University Hospital over a period of 8 months in order to develop suitable registration forms and to test feasibility. Causality, severity, type and level of intervention of the reported ADRs were analysed. Reports from physicians and nurses were compared with the data obtained by patient interviews.
During the 8 months, for 168 patients, 12 spontaneous reports were received from physicians and nurses. Fifty-six of these patients were interviewed and 32 ADRs were reported. Only 2 ADRs detected by patient interview were also reported spontaneously. The interviews of the 56 geriatric patients indicated that 20% of them were admitted to the hospital because of an ADR. ADRs occurred during hospital stay in another 20% of those patients.
Spontaneous reporting by physicians and nurses revealed considerably fewer ADRs than patient interview by pharmacists. Physicians and nurses reported the more serious ADRs that occurred during hospital stay, whereas the interviews revealed more ADRs that caused hospital admission. Our data confirm that ADRs are an important cause of hospital admission of geriatric patients and occur frequently during their hospital stay.

[show abstract][hide abstract] ABSTRACT: In 1996-1997, a drug use evaluation (DUE) of human albumin was conducted in the Ghent University Hospital (Belgium) to determine the pattern and appropriateness of the albumin use. The DUE was followed by permanent review of the albumin consumption. This paper describes how the DUE was carried out and how the albumin use in our hospital changed over time.
The study was based on criteria for indications and end of treatment, accepted by consensus of the physicians prescribing albumin. Albumin treatment episodes were classified as appropriate or inappropriate according to these criteria.
For 115 treatment episodes in 90 patients, the researchers found 21 (18.3%) deviations from the developed criteria. After analysis, half out of them were considered as minor. Most deviations involved starting treatment too early (n = 17). Follow-up results indicated that the overall consumption of albumin dropped by 50.1% from 1994 to 1999, while the consumption of colloid solutions during the same period remained stable.
A good compliance with internally developed criteria for indications and end of treatment with human albumin was observed. Discussion with the clinicians involved led to the development of stricter criteria and a continuous decrease in albumin consumption.

[show abstract][hide abstract] ABSTRACT: A total of 129 workers exposed to carbon disulphide (CS2) and 81 non-exposed controls were asked about their current use of pharmaceuticals, using a self-administered questionnaire. In all, 31% of the exposed and 19.8% of the non-exposed used some medicine (P = 0.08). The average number of pharmaceuticals per subject amounted to 0.71 in the exposed vs. 0.36 in the non-exposed (P = 0.049). Predominant types of medicines used were analgesics (12.4% in the exposed vs. 8.6% in the non-exposed, P = 0.50) and sedatives/hypnotics (10.1% in the exposed vs. 4.9% in the non-exposed, P = 0.21). The pharmaceuticals consumed can cause numerous (side) effects that are similar to the toxic effects of CS2. To take into account these possibly confounding agents, a classification system for possible (side) effects of pharmaceuticals was developed, taking the dose into account. According to this method, many (side) effects of pharmaceuticals that could occur were recorded with higher frequency and intensity in the exposed subjects. Potential (side) effects that occurred significantly more frequently in the exposed than in the non-exposed were: tiredness, sedation, dizziness (20.9% vs. 4.9%, P = 0.001), excitation, anxiety (10.9% vs. 2.5%, P = 0.03), vision disturbances (7.0% vs. 0%, P = 0.01), and erection decrease (5.4% vs. 0%, P = 0.045). The implications of these findings for epidemiological studies are discussed.

[show abstract][hide abstract] ABSTRACT: The aim of the study was to explore whether penicillin was superior to placebo in altering the clinical course of proven streptococcal pharyngitis. A randomised, parallel, double blind placebo controlled trial of 10 days duration was undertaken in 42 general practices in the Gent region (Flemish part of Belgium). Phenoxymethylpenicillin (adults 250 mg t.i.d. and children 125 mg t.i.d.) or placebo were administrated to 173 patients, aged 5 to 50 y, with acute sore throat and a positive culture for Group A beta-haemolytic streptococci. Penicillin and placebo tablets were identical. Patient compliance was monitored by assay of penicillin in urine (Sarcina lutea method). The primary outcome variable was sore throat as recorded by the physician on Day 3. The experiences of the patients themselves over the 10 day period were also assessed. Secondary outcome variables were other local and general symptoms and signs of streptococcal throat infection. In the penicillin group on Day 3, 23.2% of the patients still complained of sore throat versus 65.9% in the placebo group: difference 42.7% (C.I. 29.4%, 56.1%). This finding was confirmed by survival analysis of the symptom 'sore throat', as recorded by the patients. The physicians recorded on Day 3 a significant positive effect on another symptom (malaise: P < 0.04) and certain clinical signs (abnormal throat: P < 0.07; and redness of throat: P < 0.003). Penicillin had more adverse effects than placebo (P < 0.007). It also inhibited the rise in ASLO (P < 0.001). In this study in general practice, penicillin had a slight but definitive positive effect on the clinical evolution of streptococcal pharyngitis.(ABSTRACT TRUNCATED AT 250 WORDS)
