Manchester et al from Denver reported a series of 257 pregnancies which were complicated by suspected fetal abnormality on ultrasonography.' Thirty seven per cent of the infants born had additional anomalies not detected by prenatal ultrasonography, and the authors concluded that prenatal diagnoses based on ultrasonography were remarkably accurate but were insensitive to associated anomalies in individual cases. Our study confirms this, a revised diagnosis being made in 53 (40%) of such cases.We believe that examination of midtrimester fetuses by a clinical geneticist is a worthwhile service and improves diagnosis, which in turn benefits the diagnostic teams and parental counselling. It is best carried out by a clinician experienced in dysmorphology, used to normal variations in the appearance of fetuses at various stages in gestation, and familiar with rare dysmorphic syndromes. The collaboration of cytogeneticists and paediatric pathologists is important in defining the full extent of the anomalies in order to arrive at the final post-termination diagnosis, on which the parents will base their future reproductive decisions.We thank Dr T Andrews, regional cytogenetic servicc, anXr his staff and Dr A J Barson, department of pacdiltric pathology, University of Manchester, and his staff for their skilled work and cooperation.
Aims To examine the medication adherence among old persons living in their own homes, to assess their knowledge of their medication, and to indicate target areas for intervention. Methods A cross-sectional study of data collected from randomly selected samples of 348 persons, aged 75 years recruited from a population-based register in the municipality of Aarhus, Denmark. Information on all drugs was collected from the subjects during a home visit, and their drug storage was examined. Information was collected from the general practitioners (GP). The measures of adherence were scores of agreements between the GPs' lists and the subjects' actual drug consumption. Results We found disagreement between the drug information collected from the study population and from the GPs: concerning drugs in 22% of the study-population, concerning doses in 71%, and concerning regimens prescribed by the GP in 66%. Twenty-four percent stated that they did not always follow prescriptions. Most of the deviations from prescriptions were toward lower doses and less frequent drug intake. The drugs most often involved in deviations were hypnotics, analgesics, bronchodilators and diuretics. Sixty percent of the participants knew the purpose of medication, and 21% knew the consequences of omission of the drugs. Less than 6% of the subjects knew about the toxic risks, side-effects, or potential drug interactions. The participants' knowledge of the drugs was positively associated with their adherence. We found a correlation between an increased number of prescribed frequency of drug intake per day and deviation from the regimen (r=0.25, P=0.01). There was a positive association between nonadherence and the use of three or more drugs (odds ratio (OR) 2.5; 95% con®dence interval (CI) 1.5,4.1), prescriptions from more than one doctor (OR 2.5; 95% CI 1.3,4.8), and probability of dementia (OR 9.0; 95% CI 1.1,72.5). Moreover compliance aids facilitated adherence (OR 4.4; 95% CI 1.6,12.3). Persons living alone were more prone to medication errors (OR 2.0; 95% CI 1.1,3.5). Conclusions A differentiated evaluation of adherence by considering the drug, the dose, and the regimen separately produced quanti®able data concerning the subjects' medication habits. Non-adherence ranged from 20 to 70% depending on the measuring method. The participants' knowledge of the treatment was poor. Our results suggest that better information on medication and the use of compliance aids may prevent nonadherence. Special attention should be paid to persons receiving three or more drugs, living alone, receiving drugs from other doctors, and to persons with predementia symptoms, as they are at higher risk of nonadherence.
Almost all 75-year-old persons receive drugs. The observed polypharmacy may increase drug-related risks. The discrepancies between the GPs' knowledge of their patients' medication and the actual intake may involve a potential risk. A better registration of the patients' total medication and the implementation of a common medication database for the use of all involved physicians may improve medication and reduce risks.
Background and purpose Hip fracture (HF) in frail elderly patients is associated with poor physical recovery and death. There is often postoperative blood loss and the hemoglobin (Hb) threshold for red blood cell (RBC) transfusions in these patients is unknown. We investigated whether RBC transfusion strategies were associated with the degree of physical recovery or with reduced mortality after HF surgery.Patients and methods We enrolled 284 consecutive post-surgical HF patients (aged ≥ 65 years) with Hb levels < 11.3 g/dL (7 mmol/L) who had been admitted from nursing homes or sheltered housing. Allocation was stratified by residence. The patients were randomly assigned to either restrictive (Hb < 9.7 g/dL; < 6 mmol/L) or liberal (Hb < 11.3 g/dL; < 7 mmol/L) RBC transfusions given within the first 30 days postoperatively. Follow-up was at 90 days.Results No statistically significant differences were found in repeated measures of daily living activities or in 90-day mortality rate between the restrictive group (where 27% died) and the liberal group (where 21% died). Per-protocol 30-day mortality was higher with the restrictive strategy (hazard ratio (HR) = 2.4, 95% CI: 1.1–5.2; p = 0.03). The 90-day mortality rate was higher for nursing home residents in the restrictive transfusion group (36%) than for those in the liberal group (20%) (HR = 2.0, 95% CI: 1.1–3.6; p = 0.01).Interpretation According to our Hb thresholds, recovery from physical disabilities in frail elderly hip fracture patients was similar after a restrictive RBC transfusion strategy and after a liberal strategy. Implementation of a liberal RBC transfusion strategy in nursing home residents has the potential to increase survival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
