Medication Administration (medication + administration)
Selected AbstractsNursing Time Devoted to Medication Administration in Long-Term Care: Clinical, Safety, and Resource ImplicationsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 2 2009Mary S. Thomson PhD OBJECTIVES: To quantify the time required for nurses to complete the medication administration process in long-term care (LTC). DESIGN: Time-motion methods were used to time all steps in the medication administration process. SETTING: LTC units that differed according to case mix (physical support, behavioral care, dementia care, and continuing care) in a single facility in Ontario, Canada. PARTICIPANTS: Regular and temporary nurses who agreed to be observed. MEASUREMENTS: Seven predefined steps, interruptions, and total time required for the medication administration process were timed using a personal digital assistant. RESULTS: One hundred forty-one medication rounds were observed. Total time estimates were standardized to 20 beds to facilitate comparisons. For a single medication administration process, the average total time was 62.0±4.9 minutes per 20 residents on physical support units, 84.0±4.5 minutes per 20 residents on behavioral care units, and 70.0±4.9 minutes per 20 residents on dementia care units. Regular nurses took an average of 68.0±4.9 minutes per 20 residents to complete the medication administration process, and temporary nurses took an average of 90.0±5.4 minutes per 20 residents. On continuing care units, which are organized differently because of the greater severity of residents' needs, the medication administration process took 9.6±3.2 minutes per resident. Interruptions occurred in 79% of observations and accounted for 11.5% of the medication administration process. CONCLUSION: Time requirements for the medication administration process are substantial in LTC and are compounded when nurses are unfamiliar with residents. Interruptions are a major problem, potentially affecting the efficiency, quality, and safety of this process. [source] Legal issues in school health services and school psychology: Guidelines for the administration of medicationPSYCHOLOGY IN THE SCHOOLS, Issue 9 2009Anna Mazur-Mosiewicz The use of psychoactive medications to augment behavioral and psychosocial interventions in schools has significantly increased within the last few decades. Yet, advising, administrating, and supervising the dispensation of medication (including psychostimulants and psychoactive substances) tend to be some of the most risky tasks of school administrators and personnel. Medication administration is not only an increasing source of civil and administrative liability for school districts, but may lead to legal questions for school counselors, psychologists, and social workers. In response to growing concerns, this article provides guidelines necessary for safe medication administration and monitoring in the school setting. Federal, state, and district guidelines are reviewed. Possible implications for school and district policy makers, principals, teachers, school nurses, school psychologists, social workers, counselors, and parents are outlined. © 2009 Wiley Periodicals, Inc. [source] Barriers to adherence among adolescents with inflammatory bowel diseaseINFLAMMATORY BOWEL DISEASES, Issue 1 2010Rachel Neff Greenley PhD Abstract Background: The purpose of this study was to describe barriers to adherence among adolescents with inflammatory bowel disease (IBD) and to examine demographic, disease-related, and treatment regimen-related correlates of adherence barriers using a multimethod reporting strategy. A final goal was to examine relationships between the frequencies of barriers and levels of nonadherence. Methods: In all, 64 adolescents (ages 11,18) participated, along with 61 mothers and 25 fathers. Barriers to adherence and ratings of medication adherence were assessed via patient and parent reports. Disease activity ratings were provided by pediatric gastroenterologists. Results: Lack of time and medication side effects were commonly reported barriers across adolescent, mother, and father reports. Other adolescent-reported barriers included missing medication due to feeling well or discontinuing medication based on the belief that the medication was not working. The prevalence of adherence barriers was not consistently associated with adolescent age, sex, time since diagnosis, or disease activity. Adolescents whose regimen involved more than 1 daily medication administration had more adherence barriers based on adolescent and maternal report than did those whose regimen involved 1 or less than 1 daily medication administration. Finally, adherence barriers were significantly higher among families reporting imperfect adherence as compared to those reporting perfect adherence. Conclusions: Barriers to medication adherence do exist among adolescents with IBD and may have negative implications for medication adherence. Systematic assessment of barriers during routine medical appointments may help to identify and modify these barriers and ultimately improve adherence. Inflamm Bowel Dis 2010 [source] Effectiveness of nurse-led cardiac clinics in adult patients with a diagnosis of coronary heart diseaseINTERNATIONAL JOURNAL OF EVIDENCE BASED HEALTHCARE, Issue 1 2005Tamara Page RN BN HyperbaricNursCert GradDipNSc(HighDep) MNSc Executive summary Background, Coronary heart disease is the major cause of illness and death in Western countries and this is likely to increase as the average age of the population rises. Consumers with established coronary heart disease are at the highest risk of experiencing further coronary events. Lifestyle measures can contribute significantly to a reduction in cardiovascular mortality in established coronary heart disease. Improved management of cardiac risk factors by providing education and referrals as required has been suggested as one way of maintaining quality care in patients with established coronary heart disease. There is a need to ascertain whether or not nurse-led clinics would be an effective adjunct for patients with coronary heart disease to supplement general practitioner advice and care. Objectives, The objective of this review was to present the best available evidence related to nurse-led cardiac clinics. Inclusion criteria, This review considered any randomised controlled trials that evaluated cardiac nurse-led clinics. In the absence of randomised controlled trials, other research designs such as non-randomised controlled trials and before and after studies were considered for inclusion. Participants were adults (18 years and older) with new or existing coronary heart disease. The interventions of interest to the review included education, assessment, consultation, referral and administrative structures. Outcomes measured included adverse event rates, readmissions, admissions, clinical and cost effectiveness, consumer satisfaction and compliance with therapy. Results, Based on the search terms used, 80 papers were initially identified and reviewed for inclusion; full reports of 24 of these papers were retrieved. There were no papers included that addressed cost effectiveness or adverse events; and none addressed the outcome of referrals. A critical appraisal of the 24 remaining papers identified a total of six randomised controlled trials that met the inclusion criteria. Two studies addressed nurse-led clinics for patients diagnosed with angina, one looked at medication administration and the other looked at educational plans. A further four studies compared secondary preventative care with a nurse-led clinic and general practitioner clinic. One specifically compared usual care versus shared care introduced by nurses for patients awaiting coronary artery bypass grafting. Of the remaining three studies, two have been combined in the results section, as they are an interim report and a final report of the same study. Because of inconsistencies in reporting styles and outcome measurements, meta-analysis could not be performed on all outcomes. However, a narrative summary of each study and comparisons of specific outcomes assessed from within each study has been developed. Although not all outcomes obtained statistical significance, nurse-led clinics were at least as effective as general practitioner clinics for most outcomes. Recommendations, The following recommendations are made: ,The use of nurse-led clinics is recommended for patients with coronary heart disease (Level II). ,Utilise nurse-led clinics to increase clinic attendance and follow-up rates (Level II). ,Nurse-led clinics are recommended for patients who require lifestyle changes to decrease their risk of adverse outcomes associated with coronary heart disease (Level II). [source] Potentially Inappropriate Medication Utilization in the Emergency Department Visits by Older Adults: Analysis From a Nationally Representative SampleACADEMIC EMERGENCY MEDICINE, Issue 3 2010William J. Meurer MD Abstract Objectives:, The objectives were to determine the frequency of administration of potentially inappropriate medications (PIMs) to older emergency department (ED) patients and to examine recent trends in the rates of PIM usage. Methods:, The data examined during the study were obtained from the National Hospital Ambulatory Medical Care Survey (NHAMCS). This study utilized the nationally representative ED data from 2000,2006 NHAMCS surveys. Our sample included older adults (age 65 years and greater) who were treated in the ED and discharged home. Estimated frequencies of PIM-associated ED visits were calculated. A multivariable logistic regression model was created to assess demographic, clinical, and hospital factors associated with PIM administration and to assess temporal trends. Results:, Approximately 19.5 million patients, or 16.8% (95% confidence interval [CI] = 16.1% to 17.4%) of eligible ED visits, were associated with one or more PIMs. The five most common PIMs were promethazine, ketorolac, propoxyphene, meperidine, and diphenhydramine. The total number of medications prescribed or administered during the ED visit was most strongly associated with PIM use. Other covariates associated with PIM use included rural location outside of the Northeast, being seen by a staff physician only (and not by a resident or intern), presenting with an injury, and the combination of female sex and age 65,74 years. There was a small but significant decrease in the proportion of visits associated with a PIM over the study period. Conclusions:, Potentially inappropriate medication administration in the ED remains common. Given rising concerns about preventable complications of medical care, this area may be of high priority for intervention. Substantial regional and hospital type (teaching versus nonteaching) variability appears to exist.

Legally within Queensland, registered nurses are required to provide personal supervision for this process. Research undertaken by the authors suggests the supervision students receive frequently falls short of what is legally required. Aims and objectives., The aim of the study was to examine the factors that influence the experiences of final-year undergraduate nursing students when administering medications in the clinical setting. Design., A grounded theory approach was used with constant comparative analysis to identify categories from the data. Methods., The experiences of final-year nursing students were explored using a grounded theory approach. In-depth, semi-structured interviews were conducted with 28 final-year undergraduate nursing students in Queensland, Australia. Results., Supervision was found to be the central issue influencing medication administration for students. Three main factors were identified as influencing the supervision provided by registered nurses: attitudes of the registered nurse, communication from the university, and busyness and having time. Conclusions., The extent to which registered nurses provide direct supervision to nursing students when administering medication is influenced by factors inherent within the clinical environment. Relevance to clinical practice., The factors influencing the supervision provided by registered nurses needs further exploration that effective strategies can be implemented to ensure safe practices in relation to medication administration can be implemented. [source] The Effects of Heparin Versus Normal Saline for Maintenance of Peripheral Intravenous Locks in Pregnant WomenJOURNAL OF OBSTETRIC, GYNECOLOGIC & NEONATAL NURSING, Issue 4 2003Kathryn M. Niesen MSN, RN director of clinical nursing Objective: To compare the efficacy of two available preparations (heparin, 10 U/mL, 1 mL, vs. normal saline, 1 mL) used for maintaining patency in peripheral intravenous (IV) locks during pregnancy. Design: Prospective, randomized, and double-blind. Eligible patients who were to receive a peripheral intermittent IV lock were randomly assigned to receive either heparin flushes or normal saline flushes for IV lock maintenance. IV locks were flushed after each medication administration, or at least every 24 hours, with the assigned blinded flush solution. Intermittent IV lock sites were also evaluated every 12 hours for the development of phlebitis. Setting: A large academic medical center in the Midwest that has both community-based and regional-referral obstetric practices with more than 2,000 deliveries per year. Participants: A convenience sample included 73 hospitalized pregnant women who were between 24 and 42 weeks gestation. Exclusions from the study were women with significant abnormalities in the fetal heart tracing on admission, cervical dilation > 4 cm, presence of hypersensitivity to heparin, presence of clotting abnormalities, and anticoagulation therapy (including low-dose aspirin). Results: Data indicate there were no statistically significant differences in IV lock patency nor in phlebitis between heparin or normal saline flushes. Conclusions: This study provides support that both normal saline and heparin in the doses studied may be equally effective in the maintenance of peripheral IV locks. Due to small sample size, additional studies are needed to determine optimal therapy over time. [source] Standardizing Emergency Department,based Migraine Research: An Analysis of Commonly Used Clinical Trial Outcome MeasuresACADEMIC EMERGENCY MEDICINE, Issue 1 2010Benjamin W. Friedman MD Abstract Objectives:, Although many high-quality migraine clinical trials have been performed in the emergency department (ED) setting, almost as many different primary outcome measures have been used, making data aggregation and meta-analysis difficult. The authors assessed commonly used migraine trial outcomes in two ways. First, the authors examined the association of each commonly used outcome versus the following patient-centered variable: the research subject's wish, when asked 24 hours after investigational medication administration, to receive the same medication the next time they presented to an ED with migraine ("would take again"). This variable was chosen as the criterion standard because it provides a simple, dichotomous, clinically sensible outcome, which allows migraineurs to factor important intangibles of efficacy and adverse effects of treatment into an overall assessment of care. The second part of the analysis assessed how sensitive to true efficacy each outcome measure was by calculating sample size requirements based on results observed in previously conducted clinical trials. Methods:, This was a secondary analysis of data previously collected in four ED-based migraine randomized trials performed between 2003 and 2007. In each of these trials, subjects were asked 24 hours after administration of an investigational medication whether or not they would want to receive the same medication the next time they came to the ED with a migraine. Odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for sex and medication received, were calculated as measures of association between the most commonly used outcome measures and "would take again." The sensitivity of each outcome measure to treatment efficacy was determined by calculating the sample size that would be required to detect a statistically significant result using estimates of that outcome obtained in two clinical trials. Results:, Data from 378 subjects were used for this analysis. Adjusted ORs for association of "would take again" and other commonly used primary headache outcomes are as follows: achieving a pain-free state by 2 hours, OR = 3.1 (95% CI = 1.8 to 5.4); sustained pain-free status, OR = 4.5 (95% CI = 1.9 to 11.0); and no need for rescue medication, OR = 3.7 (95% CI = 2.1 to 6.6). An improvement on a standardized 11-point pain scale of ,33% had an adjusted OR = 5.2 (95% CI = 2.2 to 12.4). The best performing alternate outcome, ,33% improvement, correctly classified 288 subjects and misclassified 77 subjects when compared to "would take again." At least 33% improvement and pain-free by 2 hours required the smallest sample sizes, while sustained pain-free and "would take again" required many more subjects. Conclusions:, "Would take again" was associated with all migraine outcome measures we examined. No individual outcome was more closely associated with "would take again" than any other. Even the best-performing alternate outcome misclassified more than 20% of subjects. However, sample sizes based on "would take again" tended to be larger than other outcome measures. On the basis of these findings and this outcome measure's inherent patient-centered focus, "would take again," included as a secondary outcome in all ED migraine trials, is proposed.

[source] The attitudes and beliefs of healthcare professionals on the causes and reporting of medication errors in a UK Intensive care unitANAESTHESIA, Issue 1 2007I. S. Sanghera Summary Our aim was to explore the attitudes and beliefs of healthcare professionals relating to the causes and reporting of medication errors in a UK intensive care unit. Medication errors were identified by the unit pharmacist and semi-structured qualitative interviews conducted with 13 members of staff involved with 12 errors. Interviews were analysed using a model of human error theory. Staff identified many contributing factors, including poor communication and frequent interruptions. Organisational factors included lack of clarity on the responsibility of the second nurse's check for medication administration, lack of feedback on medication errors, and a common and accepted practice of administering medication without a complete medication order. Barriers to reporting included administrative paperwork and lack of encouragement by management. Greater feedback on medication errors seems essential to improve current practice and increase reporting. [source] Ibuprofen Provides Analgesia Equivalent to Acetaminophen,Codeine in the Treatment of Acute Pain in Children with Extremity Injuries: A Randomized Clinical TrialACADEMIC EMERGENCY MEDICINE, Issue 8 2009Janet H. Friday MD Abstract Objectives:, This study compared the analgesic effectiveness of acetaminophen,codeine with that of ibuprofen for children with acute traumatic extremity pain, with the hypothesis that the two medications would demonstrate equivalent reduction in pain scores in an emergency department (ED) setting. Methods:, This was a randomized, double-blinded equivalence trial. Pediatric ED patients 5 to 17 years of age with acute traumatic extremity pain received acetaminophen,codeine (1 mg/kg as codeine, maximum 60 mg) or ibuprofen (10 mg/kg, maximum 400 mg). The patients provided Color Analog Scale (CAS) pain scores at baseline and at 20, 40, and 60 minutes after medication administration. The primary outcome measured was the difference in changes in pain score at 40 minutes, compared to a previously described minimal clinically significant change in pain score of 2 cm. The difference was defined as (change in ibuprofen CAS score from baseline) , (change in acetaminophen,codeine CAS score from baseline); negative values thus favor the ibuprofen group. Additional outcomes included need for rescue medication and adverse effects. Results:, The 32 acetaminophen,codeine and the 34 ibuprofen recipients in our convenience sample had indistinguishable pain scores at baseline. The intergroup differences in pain score change at 20 minutes (,0.6, 95% confidence interval [CI] = ,1.5 to 0.3), 40 minutes (,0.4, 95% CI = ,1.4 to 0.6), and 60 minutes (0.2, 95% CI = ,0.8 to 1.2) were all less than 2 cm. Adverse effects were minimal: vomiting (one patient after acetaminophen,codeine), nausea (one patient after ibuprofen), and pruritus (one after acetaminophen,codeine). The three patients in each group who received rescue medications all had radiographically demonstrated fractures or dislocations. Conclusions:, This study found similar performance of acetaminophen,codeine and ibuprofen in analgesic effectiveness among ED patients aged 5,17 years with acute traumatic extremity pain. Both drugs provided measurable analgesia. Patients tolerated them well, with few treatment failures and minimal adverse effects. [source] Oral versus Intravenous Opioid Dosing for the Initial Treatment of Acute Musculoskeletal Pain in the Emergency DepartmentACADEMIC EMERGENCY MEDICINE, Issue 12 2008James R. Miner MD Abstract Objectives:, The objective was to compare the time to medication administration, the side effects, and the analgesic effect at sequential time points after medication administration of an oral treatment strategy using oxycodone solution with an intravenous (IV) treatment strategy using morphine sulfate for the initial treatment of musculoskeletal pain in emergency department (ED) patients. Methods:, This was a prospective randomized clinical trial of patients >6 years old who were going to receive IV morphine sulfate for the treatment of musculoskeletal pain but did not yet have an IV. Consenting patients were randomized to have the treating physician order either 0.1 mg/kg morphine sulfate IV or 0.125 mg/kg oxycodone orally in a 5 mg/5 mL suspension as their initial treatment for pain. The time from the placement of the order to the administration of the medication was recorded. Pain was measured using a 100-mm visual analog scale (VAS) and recorded at 0, 10, 20, 30 and 40 minutes after drug administration. Results:, A total of 405 eligible patients were identified during the study period; 328 (81.0%) patients consented to be in the study. A total of 158 patients were randomized to the IV morphine sulfate treatment group, and 162 were randomized to the oral oxycodone treatment group. Of the patients who were randomized to IV therapy, 34 were withdrawn from the study prior to drug administration; leaving 125 patients in the IV group for analysis. Of the patients who randomized to oral therapy, 22 were withdrawn from the study prior to drug administration, leaving 140 patients for analysis. No serious adverse events were detected. There was a 12-minute difference between the median time of the order and the administration of oral oxycodone (8.5 minutes) and IV morphine (20.5 minutes). The mean percent change in VAS score was larger for patients in the IV therapy group than those in the oral therapy group at 10 and 20 minutes. At 30 and 40 minutes, the authors could no longer detect a difference. The satisfaction scale score was higher after treatment for the morphine group (median = 4; interquartile range [IQR] = 4 to 5) than for the oxycodone group (median = 4; IQR = 2 to 5; p = 0.008). Conclusions:, The oral loading strategy was associated with delayed onset of analgesia and decreased patient satisfaction, but a shorter time to administration. The oral loading strategy using an oxycodone solution provided similar pain relief to the IV strategy using morphine 30 minutes after administration of the drug. Oral 0.125 mg/kg oxycodone represents a feasible alternative to 0.1 mg/kg IV morphine in the treatment of severe acute musculoskeletal pain when difficult or delayed IV placement greater than 30 minutes presents a barrier to treatment. [source] Emergency Department Crowding and Decreased Quality of Pain CareACADEMIC EMERGENCY MEDICINE, Issue 12 2008Ula Hwang MD Abstract Objectives:, The objective of this study was to evaluate the association of emergency department (ED) crowding factors with the quality of pain care. Methods:, This was a retrospective observational study of all adult patients (,18 years) with conditions warranting pain care seen at an academic, urban, tertiary care ED from July 1 to July 31, 2005, and December 1 to December 31, 2005. Patients were included if they presented with a chief complaint of pain and a final ED diagnosis of a painful condition. Predictor ED crowding variables studied were 1) census, 2) number of admitted patients waiting for inpatient beds (boarders), and 3) number of boarders divided by ED census (boarding burden). The outcomes of interest were process of pain care measures: documentation of clinician pain assessment, medications ordered, and times of activities (e.g., arrival, assessment, ordering of medications). Results:, A total of 1,068 patient visits were reviewed. Fewer patients received analgesic medication during periods of high census (>50th percentile; parameter estimate = ,0.47; 95% confidence interval [CI] = ,0.80 to ,0.07). There was a direct correlation with total ED census and increased time to pain assessment (Spearman r = 0.33, p < 0.0001), time to analgesic medication ordering (r = 0.22, p < 0.0001), and time to analgesic medication administration (r = 0.25, p < 0.0001). There were significant delays (>1 hour) for pain assessment and the ordering and administration of analgesic medication during periods of high ED census and number of boarders, but not with boarding burden. Conclusions:, ED crowding as measured by patient volume negatively impacts patient care. Greater numbers of patients in the ED, whether as total census or number of boarders, were associated with worse pain care. [source] Olanzapine versus Droperidol for the Treatment of Primary Headache in the Emergency DepartmentACADEMIC EMERGENCY MEDICINE, Issue 9 2008Chandler H. Hill MD Abstract Objectives:, The objective was to determine if there is a difference in pain relief or frequency and severity of side effects in emergency department (ED) patients with primary headache treated with either intramuscular (IM) olanzapine or IM droperidol. Methods:, This was a prospective, randomized nonblinded clinical trial of adult ED patients undergoing treatment for suspected primary headache. Consenting patients were randomized to receive either droperidol 5 mg IM or olanzapine 10 mg IM. Prior to receiving treatment, patients were asked to complete a 100-mm visual analog scale (VAS) describing their pain and a 4-point verbal rating scale (VRS) describing their pain as none, mild, moderate, or severe. Patients also completed a 100-mm VAS describing their level of nausea. Pain and nausea measurements were repeated 30 and 60 minutes after medication administration. Patients also completed the Barnes Akathisia Scale (BAS) 30 and 60 minutes after medication administration. Descriptive statistics were used as appropriate. Pain relief was compared both in terms of the decrease in VAS scores and in the proportion of patients who reported moderate or severe pain whose report later changed to mild or no pain. Results:, One-hundred patients were enrolled; 13 were withdrawn before administration of the study medication, 8 in the droperidol group and 5 in the olanzapine group, leaving 87 patients for analysis. Forty-two patients received droperidol and 45 received olanzapine. In the droperidol group, 35/40 (87.5%) patients who had reported moderate or severe pain at baseline reported mild or no pain at 60 minutes. In the olanzapine group, 38/44 (86.4%) reported this change (p = 0.89). The mean percent change from baseline VAS pain score at 60 minutes was ,37% (95% CI = ,84% to 11%) for droperidol and ,37% (95% CI = ,64% to 10%) for olanzapine (p = 0.30). The mean percent change from baseline for the VAS nausea score was ,59% (95% CI = ,70% to ,47%) for droperidol and ,64% (95% CI = ,77% to ,51%) for olanzapine (p = 0.83). There was no difference in any report of akathisia by the BAS between the groups (p = 0.63). Conclusions:, Both olanzapine and droperidol are effective treatments for primary headaches in the ED. No significant differences were found between the medications in terms of pain relief, antiemetic effect, or akathisia. Olanzapine may be used to treat primary headache and it is an effective alternative to droperidol. [source] REVIEW ARTICLE: Reducing fracture risk with calcium and vitamin DCLINICAL ENDOCRINOLOGY, Issue 3 2010Paul Lips Summary Studies of vitamin D and calcium for fracture prevention have produced inconsistent results, as a result of different vitamin D status and calcium intake at baseline, different doses and poor to adequate compliance. This study tries to define the types of patients, both at risk of osteoporosis and with established disease, who may benefit from calcium and vitamin D supplementation. The importance of adequate compliance in these individuals is also discussed. Calcium and vitamin D therapy has been recommended for older persons, either frail and institutionalized or independent, with key risk factors including decreased bone mineral density (BMD), osteoporotic fractures, increased bone remodelling as a result of secondary hyperparathyroidism and increased propensity to falls. In addition, treatment of osteoporosis with a bisphosphonate was less effective in patients with vitamin D deficiency. Calcium and vitamin D supplementation is a key component of prevention and treatment of osteoporosis unless calcium intake and vitamin D status are optimal. For primary disease prevention, supplementation should be targeted to those with dietary insufficiencies. Several serum 25-hydroxyvitamin D (25(OH)D) cut-offs have been proposed to define vitamin D insufficiency (as opposed to adequate vitamin D status), ranging from 30 to 100 nmol/l. Based on the relationship between serum 25(OH)D, BMD, bone turnover, lower extremity function and falls, we suggest that 50 nmol/l is the appropriate serum 25(OH)D threshold to define vitamin D insufficiency. Supplementation should therefore generally aim to increase 25(OH)D levels within the 50,75 nmol/l range. This level can be achieved with a dose of 800 IU/day vitamin D, the dose that was used in succesfull fracture prevention studies to date; a randomized clinical trial assessing whether higher vitamin D doses achieve a greater reduction of fracture incidence would be of considerable interest. As calcium balance is not only affected by vitamin D status but also by calcium intake, recommendations for adequate calcium intake should also be met. The findings of community-based clinical trials with vitamin D and calcium supplementation in which compliance was moderate or less have often been negative, whereas studies in institutionalized patients in whom medication administration was supervised ensuring adequate compliance demonstrated significant benefits.
