Repeat prescribing processes in primary care: a qualitative study

Objective To investigate the characteristics, local agreements and changes regarding repeat prescribing processes in primary health care in Finland. Setting Twenty‐eight municipal health centres nationwide. Method Twenty‐eight physicians and 28 medical receptionists were given semi‐structured telephone interviews about repeat prescribing practices. The repeat prescribing process of each health centre was displayed as a flow chart and the processes were classified according to the quality of the practical flow and the medication review. Key findings There are various ways of carrying out repeat prescribing in different health centres. In some centres, a review of the medications is recognised as part of the repeat prescribing process, but in others there is no systematic review of the patients' medication. Repeat prescribing is often performed in a busy atmosphere. Repeat prescribing systems have evolved over time without proper management, and few local guidelines exist. Conclusions There is a need to reorganise the repeat prescribing systems in primary health care. A regular review of long‐term medications, in particular, needs to become a part of the repeat prescribing process. There is a need for both local and national guidelines.

Increasing homogeneity in global food supplies and the implications for food security

The narrowing of diversity in crop species contributing to the world’s food supplies has been considered a potential threat to food security. However, changes in this diversity have not been quantified globally. We assess trends over the past 50 y in the richness, abundance, and composition of crop species in national food supplies worldwide. Over this period, national per capita food supplies expanded in total quantities of food calories, protein, fat, and weight, with increased proportions of those quantities sourcing from energy-dense foods. At the same time the number of measured crop commodities contributing to national food supplies increased, the relative contribution of these commodities within these supplies became more even, and the dominance of the most significant commodities decreased. As a consequence, national food supplies worldwide became more similar in composition, correlated particularly with an increased supply of a number of globally important cereal and oil crops, and a decline of other cereal, oil, and starchy root species. The increase in homogeneity worldwide portends the establishment of a global standard food supply, which is relatively species-rich in regard to measured crops at the national level, but species-poor globally. These changes in food supplies heighten interdependence among countries in regard to availability and access to these food sources and the genetic resources supporting their production, and give further urgency to nutrition development priorities aimed at bolstering food security.A shared axiom of ecology and nutrition is that, within certain ranges, diversity enhances the health and function of complex biological systems. Species diversity has been shown to stimulate productivity, stability, ecosystem services, and resilience in natural (1–5) and in agricultural ecosystems (6–13). Likewise, variation in food species contributing to diet has been associated with nutritional adequacy (14–17) and food security (18).The development of sedentary agricultural societies and further rise of modern agriculture is generally considered to have led to a decline in the total number of plant species upon which humans depend for food (19, 20), particularly the wild, semidomesticated, and cultivated vegetables and fruits, spices, and other food plants that supplemented staple crops with the provision of micronutrients and that bolstered food security historically during crop failures (21). Harlan (20) warned that

most of the food for mankind comes from a small number of crops and the total number is decreasing steadily. In the United States in the past 40 years, many vegetables and fruits have disappeared from the diet, and the trend is going on all over the world. More and more people will be fed by fewer and fewer crops.

More recent analyses of dietary transition in developing countries in association with globalization have noted increases in the diversity of plants contributing to diets locally, along with a Westernization transition in preference of energy-dense foods (i.e., animal products, plant oils, and sugars) over cereals, pulses, and vegetables, and of particular major crop plants within these food categories over traditional crops (22, 23). The impact of such changes on overall crop diversity worldwide has not been comprehensively documented, although recent changes in varietal and allelic level diversity of some crops have been investigated (24–26). Given the potential food security implications of narrowing of the diversity of crop species both in production systems and in food supplies, an assessment of the global state of crop plant species diversity is warranted.Here we examine changes in the diversity of the portfolio of crop species upon which humans primarily depend for food security in regard to calories, protein, fat, and food weight. Using national per capita food supply data published by the Food and Agriculture Organization (FAO) of the United Nations, we analyzed trends in the richness, abundance, and composition of measured crop commodities in the food supplies of 152 countries comprising 98% of the world’s population from 1961 to 2009.

Antibacterial resistance in Streptococcus pyogenes (GAS) from healthy carriers and tonsillitis patients and association with antibacterial sale in the Faroe Islands

The aim of this study was to investigate the antibacterial resistance of Streptococcus pyogenes (GAS), and correlate the findings with the sales of erythromycin and tetracycline. General practitioners in the Faroe Islands were recruited to send oropharyngeal swabs. From an ongoing pneumococcal study, nasopharyngeal swabs were sampled from healthy children 0–7 years of age. Erythromycin susceptibility data from Iceland were obtained from the reference laboratory at the Landspitali University Hospital. Susceptibility testing in the Faroe Islands and Iceland was performed according to CLSI methods and criteria. The resistance rate to erythromycin and tetracycline found in patients in the Faroe Islands in 2009/2010 was 6% and 30% respectively. Tetracycline resistance in patients declined significantly from 2009 to 2010 (37–10%, p‐value = 0.006 < 0.05) and differed significantly between age groups (p‐value = 0.03 < 0.05). In Iceland, there was a peak in erythromycin resistance in 2008 (44%) and a substantial decrease in 2009 (5%). Although the prevalence of erythromycin and tetracycline resistance in the Faroe Islands and Iceland may be associated with antimicrobial use, sudden changes can occur with the introduction of new resistant clones.     

Estimating the final outcome of brace treatment for idiopathic thoracic scoliosis at 6-month follow-up

OBJECTIVE: The study was conducted on the possibility of predicting the final outcome of bracing for idiopathic scoliosis at a follow-up period of 6 months. METHODS: In a retrospective study, 62 adolescent female patients with right thoracic scoliosis (20-40 degrees Cobb angle) treated with a brace were examined. A new compliance score was developed. The sample was divided into four groups based on compliance (compliance score) and initial correction (half-year after start bracing): group A, good compliance/high initial correction; group B, good compliance/low initial correction; group C, bad compliance/high initial correction; group D, bad compliance/low initial correction. The final outcome (1 year after weaning) was defined as successful if a curve correction of at least 5 degrees was achieved. The influence of factors on final outcome was analysed by ANOVA. Differences between continuous data were analysed by a two-sample Wilcoxon test. RESULTS: The overall final outcome was not successful (thoracic curve -3 degrees). However, the average outcome of the compliant group was successful (-5 degrees), while no success was achieved without good compliance (+5 degrees). High initial correction of more than 40% (p < 0.002) and good compliance (p< 0.004) were of significant impact for the outcome. Patients showing good compliance and high initial correction presented a successful outcome of 7 degrees Cobb angle. CONCLUSION: Compliant patients with a high initial correction can expect a final correction of around 7 degrees, while compliant patients with low initial correction may maintain the curve extent. Bad compliance is always associated with curve progression.
