Resident characteristics and organizational factors influencing the quality of drug use in Swedish nursing homes.

Appropriateness of drug use is an important indicator of the quality of care in nursing homes. In this study, we analyzed the influence of resident characteristics and selected organizational factors on the appropriateness of psychotropic drug use in 33 Swedish nursing homes. Specific criteria based on published guidelines and recommendations were developed to measure appropriateness. Residents diagnosed with a psychiatric disorder and younger residents had more deviations from the criteria; however, resident mix did not explain variations in appropriateness of drug use at the facility level. Facilities with better nurse staffing and drug intervention teams had fewer deviations from the criteria, but only 15-20% of the variation in drug prescribing was explained by these predictors.

Physician and staff assessments of drug interventions and outcomes in Swedish nursing homes.

OBJECTIVE: To describe the type and frequency of drug-related problems discussed in regular team meetings conducted in 15 Swedish nursing homes and report physician and staff assessments of these interventions and residents' outcomes. DATA SOURCES AND METHODS: The data were collected within the context of a controlled trial with the primary aim of exploring the effects of regular team interventions on drug prescribing practices in Swedish nursing homes. In 15 experimental nursing homes, the residents' drug therapy was discussed regularly by a team consisting of a pharmacist, a physician, nurses, undernurses (similar to licensed practical nurses), and nurse's aides. The pharmacist documented problems, made changes, and observed outcomes. Following the intervention period, a questionnaire was sent to the medical staff that contained items regarding perceived outcomes, the intervention's impact on knowledge of drug therapy in the elderly, and attitudes toward the pharmacist's role. RESULTS: Unclear indication and problematic choice of drugs were the most common drug-related problems discussed. In 19% of the situations, therapy changes were reported to have had a beneficial effect on the residents' clinical status; in 47% of the situations, staff reported no observable outcome from changes, suggesting that the changes had been appropriate. Finally, medical staff claimed in the follow-up survey that their knowledge about drug therapy had increased; they expressed an overall positive attitude toward this interactive collaboration. CONCLUSIONS: Regular intervention conducted by a multidisciplinary team incorporating a pharmacist can effectively improve prescribing practices, increase staff knowledge about appropriate drug therapy in the elderly, and result in improved quality of care for nursing home residents.

The impact of regular multidisciplinary team interventions on psychotropic prescribing in Swedish nursing homes.

OBJECTIVE: To evaluate the impact of regular multidisciplinary team interventions on the quantity and quality of psychotropic drug prescribing in Swedish nursing homes. DESIGN: A randomized controlled trial. SETTING: A sample of 33 nursing homes: 15 experimental homes and 18 control homes representing 5% of all Swedish nursing homes. PARTICIPANTS: The sample consisted of 1854 long-term care residents with an average age of 83 years. Seventy percent of the residents were women, and 42% had a documented diagnosis of dementia. An additional 5% had a psychotic disorder, and 7% had a diagnosis of depression. INTERVENTION: Experimental homes participated in an outreach program that was designed to influence drug use through improved teamwork among physicians, pharmacists, nurses, and nurses' assistants. Multidisciplinary team meetings were held on a regular basis throughout the 12-month study period. MEASUREMENTS: Lists of each resident's prescriptions were collected 1 month before and 1 month after the 12-month intervention. Measures included the proportion of residents with any psychotropic drug, polymedicine, and therapeutic duplication and proportion of residents with nonrecommended and acceptable drugs in each psychotropic drug class, as defined by current Swedish guidelines. RESULTS: Baseline results show extensive psychotropic drug prescribing, with the most commonly prescribed drugs being hypnotics (40%), anxiolytics (40%), and antipsychotics (38%). After 12 months of team meetings in the experimental homes, there was a significant decrease in the prescribing of psychotics (-19%), benzodiazepine hypnotics (-37%), and antidepressants (-59%). Orders for more acceptable antidepressants also increased in the experimental homes. In the control homes there was increased use of acceptable antidepressants, but there were no significant reductions in other drug classes. CONCLUSIONS: There is excessive prescription of psychotropic drugs in Swedish nursing homes. Improved teamwork among caregivers can improve prescribing as defined by clinical guidelines.

Advertisements for medicines in leading medical journals in 18 countries: a 12-month survey of information content and standards.

The information content of 6,710 advertisements for medicines in medical journals was surveyed to provide a baseline for monitoring the effect of WHO's Ethical Criteria for Medicinal Drug Promotion. The advertisements (ads) appeared during 12 months (1987-1988) in 23 leading national medical journals in 18 countries. Local participants, mostly doctors or pharmacists, examined them. The presence or absence in each ad of important information was noted. In most ads the generic name appeared in smaller type than the brand name. Indications were mentioned more often than the negative effects of medicines. The ads gave less pharmacological than medical information. However, important warnings and precautions were missing in half, and side effects and contraindications in about 40 percent. Prices tended to be given only in countries where a social security system pays for the medicines. The information content of ads in the developing countries differed surprisingly little from that in the industrialized countries. Almost all the ads (96 percent) included one or more pictures; 58 percent of these were considered irrelevant. The authors believe it is a mistake to regard ads as trivial. If they are not considered seriously they will influence the use of medicines as they are intended to do, but read critically they can provide useful information.

Evaluation of a prescription based record-linkage model for epidemiological studies of long-term adverse effects of drugs--with special regard to combined oral contraceptives.

The Department of Drugs of the Swedish National Board of Health and Welfare undertook a study of the possibilities of a new scheme for post-marketing surveillance by means of prescription and register based epidemiological studies, primarily of combined oral contraceptives (COC). Based on available data on COC usage patterns and incidence rates of the disease at study, it was estimated that study periods, including the necessary time periods for disease development and generation of a sufficient number of cases, would amount to at least 1 to 13 years for cardiovascular outcomes and 8 to 17 years for reproductive cancers. Prospective and unbiased exposure ascertainment would be the most important advantage. However, delay in follow up, the need for extensive individual questionnaire probing and fear of violation of personal integrity could adversely affect the feasibility of the scheme. Chiefly on the grounds of the extended study periods and magnitude of the necessary infrastructure, it was not judged cost-effective to pursue such a scheme for COC exposure only. It was, however, suggested that it would be considered for epidemiological surveillance of other drugs that are commonly used and for which short term and frequent serious side effects are expected, as for instance lipid lowering compounds, beta-blockers, bensodiazepines and other psychotropic drugs.

On the differences in psychotropic drug use between the three major urban areas in Sweden.

Marked differences in the utilisation of psychotropic drugs between the three major urban areas in Sweden were recorded from four sources of information: drug supplies from wholesalers to pharmacies, drug supplies to hospitals for in-patient use, drugs sold on prescription for out-patient use, and out-patient consultation and drug prescribing as recorded by physicians. The total sales of psychotropics in the counties of Gothenburg (110.8 defined daily doses per 1000 inhabitants per day) and Malmö (102.1) were much higher than in the county of Stockholm (73.4), with about 25% of the difference being accounted for by diazepam. Differences in the total sales of psychotropics were not explained by any differences in hospital sales, which amounted to about 10% in all counties. Prescription sales differed due to the higher average number of DDD (defined daily doses) per prescription in Gothenburg and Malmö than in Stockholm (total psychotropics 8 and 15%, respectively), and especially because of the higher number of prescriptions per inhabitant (about 40 and 30-35%, respectively). There was no substantial difference in the pattern of diagnoses between areas, but there was a noticeable difference with regard to prescriber category, as psychiatrists accounted for more of the prescriptions in Stockholm than in Gothenburg and Malmö. The results raise questions about over- and under-treatment of mental disorders and about abuse of drugs. In order to explain the geographical differences in psychotropic drug sales morbidity patterns and prescribing practices should be further explored.

Studies on drug utilization: bilateral case study in Poland and Sweden.

The utilization of drugs in Poland and Sweden was compared by two means: the defined daily doses (DDD) and the price-adjusted sales figures (PASF). Obtained results imply that the total pharmaceutical consumption in the countries under study is almost equal: in Poland-US $114.47 and in Sweden-US $109.77 per inhabitant. However, in particular groups and subgroups of drugs, significant differences in prescribing exist (Tables 1 and 2). Awareness of these may help doctors to improve their prescribing of drugs, and may prompt further studies on drug utilization where irrational use of drugs is not evident but suspected.
