Drug—Drug Interactions in the Elderly

OBJECTIVE: To detect the frequency of potential drug—drug interactions (DDIs) in an outpatient group of elderly people in 6 European countries, as well as to describe differences among countries. DATA SOURCES AND METHODS: Drug use data were collected from 1601 elderly persons living in 6 European countries. The study population participated in a controlled intervention study over 18 months investigating the impact of pharmaceutical care. Potential DDIs were studied using a computerized detection program. RESULTS: The elderly population used on average 7.0 drugs per person; 46% had at least 1 drug combination possibly leading to a DDI. On average, there were 0.83 potential DDIs per person. Almost 10% of the potential DDIs were classified to be avoided according to the Swedish interaction classification system, but nearly one-third of them were to be avoided only for predisposed patients. The risk of subtherapeutic effect as a result of a potential DDI was as common as the risk of adverse reactions. Furthermore, we found differences in the frequency and type of potential DDIs among the countries. CONCLUSIONS: Potential DDIs are common in elderly people using many drugs and are part of a normal drug regimen. Some combinations are likely to have negative effects; more attention must be focused on detecting and monitoring patients using such combinations. As differences in potential DDIs among countries were found, the reasons for this variability need to be explored in further studies.

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.

Quality of drug prescribing in elderly people in nursing homes and special care units for dementia: a cross-sectional computerized pharmacy register analysis.

AbstractBackground: Drug prescribing to the elderly is extensive and often inappropriate. Furthermore, the number of drugs used is the most important risk factor for adverse drug reactions. Despite this, drug prescribing in the elderly in Sweden is high and increasing. In 2003 the Swedish National Board of Health and Welfare launched a set of indicators to evaluate the quality of drug therapy in the elderly. Use of this tool in combination with the Swedish computerized national register covering all persons receiving multi-dose drug dispensing (drugs dispensed in one dose unit bag for each dose occasion) would enable detection of inappropriate drug prescribing and could help reduce the risk of drug-related problems among the elderly. Objectives: To assess the extent and quality of drug prescribing in younger and older elderly residents receiving multi-dose drug dispensing in ordinary nursing homes (NHs) and special care units for dementia (NHDs), and to evaluate the relationship between the quality of prescribing and the number of prescribers per resident, in a Swedish county. Methods: The computerized national pharmacy drug register provided the database and a cross-sectional design was used. Selected drug-specific quality indicators proposed by the Swedish National Board of Health and Welfare in 2003 were used to assess the quality of drug prescribing. Results: This study included 3705 residents. Their mean age was 85 years and 72% were women. The mean number of prescribed drugs was 10.3 per resident. The proportion of residents with prescriptions for psychotropic drugs was 80% in NHs and 85% in NHDs. The prevalence of each drug-specific quality indicator was as follows: long-acting benzodiazepines 16.4% (NHs) versus 11.7% (NHDs), anticholinergic drugs 20.7% versus 18.5%, drug duplication 14.6% versus 13.6%, three or more psychotropic drugs 25.6% versus 35.3%, class C interactions (drug combinations that may require dose adjustment) 41.9% versus 38.7% and class D interactions (drug combinations that should be avoided) 8.1% versus 5.6%. Younger elderly residents (age 65–79 years) had a lower quality of drug prescribing. An increasing number of prescribers per resident was associated with a lower quality of drug therapy. Conclusions: We found a lower quality of drug prescribing, e.g. anticholinergic drugs prescribed to approximately 20% of residents of NHs and NHDs, and a higher rate of psychotropic drug use (≥80%) compared with previous studies in NHs. Our results also demonstrated a negative correlation between quality of prescribing and number of prescribers per resident.

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.

Developing the role of the drug and therapeutics committees: perceptions of chairs

PURPOSE According to Swedish law, every county is required to have a local drug and therapeutics committee (DTC) to contribute to safe and cost-effective drug use. The law presents merely a framework and gives no detailed instructions addressing, for example, organisation and methods. The aim of this study is to explore the variation of conceptions of the role of the DTCs among committee Chairs and to compare the results with an earlier study. DESIGN/METHODOLOGY/APPROACH Data were collected by questionnaires and telephone interviews with committee chairs, which were analysed using a phenomenographic approach. FINDINGS Four conceptions were identified, namely: traditional, patient-aware, influential, holistic and cooperative, which all involved prescribers. In one conception the DTC acted as an expert to decision-makers. One conception included the notion that cooperation across the bureaucratic borders was important. Patients were involved in two conceptions. Comparison with the earlier study showed a trend toward higher patient awareness and a higher agreement on DTC goals with an increased focus on quality issues. ORIGINALITY/VALUE This study demonstrates an alternative research method bringing in new perspectives when exploring activities within healthcare. Patient involvement in the work of the DTCs is increasing, but should be further explored and developed.

The 2015 National Cancer Program in Sweden: Introducing standardized care pathways in a decentralized system

Starting in 2015, the Swedish government has initiated a national reform to standardize cancer patient pathways and thereby eventually speed up treatment of cancer. Cancer care in Sweden is characterized by high survival rates and a generally high quality albeit long waiting times. The objective with the new national program to standardize cancer care pathways is to reduce these waiting times, increase patient satisfaction with cancer care and reduce regional inequalities. A new time-point for measuring the start of a care process is introduced called well-founded suspicion, which is individually designed for each cancer diagnosis. While medical guidelines are well established earlier, the standardisation is achieved by defining time boundaries for each step in the process. The cancer reform program is a collaborative effort initiated and incentivized by the central government while multi-professional groups develop the time-bound standardized care pathways, which the regional authorities are responsible for implementing. The broad stakeholder engagement and time-bound guidelines are interesting approaches to study for other countries that need to streamline care processes.

Patient-centredness as a quality domain in Swedish healthcare: results from the first national surveys in different Swedish healthcare settings

Objectives Patients’ perception of the quality and patient-centredness of healthcare has gained increasing interest in the last decade in Sweden, as in other countries. The purpose of the study was to evaluate to what extent patients perceived Swedish healthcare as patient-centred and to explore the satisfaction levels related to gender, education level and to having or not having Swedish as ones mother tongue. Design and settings This study has a cross-sectional design. Analyses were based on the first national patient surveys in Sweden, conducted between 2009 and 2010. The surveys included responses from 232 518 patients who had been in contact with primary, outpatient, inpatient, or emergency care units. Survey questions related to indicators of patient-centred care and sociodemographic variables were selected for the analysis. The patients’ level of satisfaction in the selected indicators was analysed and compared by sociodemographic and background factors. Multivariable logistic regression models were used for analysis. Results The patients expressed high levels of satisfaction in questions related to the ‘Respect’ indicator (81–96% satisfied) but lower levels in most of the other indicators of patient-centred care. Only 25–30% of the patients reported they had been told about possible warning signs of their condition or treatment and 58–66% said they had received enough information about their condition. Group differences were detected. The most satisfied patient groups were men, individuals with low levels of education and those with Swedish as their mother tongue. Conclusions According to these first national patient surveys, achieving patient-centred healthcare for all citizens is a challenge for Swedish healthcare authorities. Future analyses of national patient surveys should show whether national efforts to encourage acceptance of patient-centred approaches and strategies for equal care will give intended results.

The national program on standardized cancer care pathways in Sweden: Observations and findings half way through

In 2015, the Swedish government initiated a national cancer reform program to standardize cancer care pathways. Primary aims included shortened waiting times among patients with suspected cancer, increased patient satisfaction and reduced regional variation. The implementation phase of the program is now more than half way through and both achievements and challenges have been identified. The ongoing evaluation demonstrates that professional engagement and adjustments on the meso- and micro-level of the system are essential to achieving sustainable improvements. Waiting times have shortened for the pathways launched first, and patients are satisfied with a more transparent process. Physicians in primary care are satisfied to inform patients about the pathways but point out problems with comorbidity and complicated diagnostic procedures related to unspecific symptoms. Mechanisms and ethical considerations behind possible crowding-out effects need to be thoroughly highlighted and discussed with staff and management. The results so far appear promising but meso- and micro-levels of the system need to be more involved in the design processes.
