Prescribing errors on medical wards and the impact of clinical pharmacists

INTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 1 2003
Ms Alison Dale clinical services pharmacist
Objectives To assess the incidence of prescribing errors, predict patient outcome from clinical pharmacists' recommendations made in response to identified prescribing errors, and evaluate the influence of clinical pharmacists on recommendation implementation. Method Clinical pharmacy activities were conducted on two wards, one of which had an existing clinical pharmacy service (intervention ward) while the other did not (control ward). For the control ward, prescribing errors were documented but not followed up unless a potentially life-threatening problem was identified. Prescribing errors were identified and recommendations made by pharmacists. A consultant physician and pharmacist conducted an independent, blinded assessment of these recommendations to predict the impact on patient outcome if implemented. Recommendations were communicated to medical staff or implemented by the pharmacist on the intervention ward only. The proportion of recommendations implemented for intervention and control group patients were recorded. Setting Two medical wards in a UK district general hospital. The study was carried out over 12 weeks. Key findings There were 740 errors recorded for 235 patients. Fourteen recommendations could not be assessed. For all recommendations, the consultant and pharmacist predicted patient outcomes with life-saving (one consultant vs three pharmacist), major (186 vs 318), minor (328 vs 324), neutral (211 vs 85) or harmful (five vs five) impact respectively. For the intervention group, 79% of recommendations were implemented, including 81 of 92 (88%) predicted by the consultant to have major impact on patient outcomes. In the control group, only 18% of recommendations were spontaneously implemented, including only 10 of 94 (11%) recommendations predicted by the consultant to have major impact. Conclusion Ward-based clinical pharmacists identified large numbers of prescribing errors and made clinically significant recommendations. Implementation of recommendations was predicted to improve the outcome of patient care. Further research, specifically assessing the outcome of pharmacists' recommendations on patient care, is warranted. [source]

Safe medication practice: attitudes of medical students about to begin their intern year

MEDICAL EDUCATION, Issue 4 2008
Ian D Coombes
Objectives, Interns are expected to prescribe effectively and safely. This study aimed to assess medical students' perceptions of their readiness to prescribe, associated risks and outcome if involved in an error, as well as their perceptions of available support. Methods, We carried out a survey of 101 students prior to their intern year using a structured questionnaire. An indication of agreement with 21 closed statements was sought. Thematic clusters were identified by factor analysis. Results, Most students (84) felt they would be able to prescribe for most simple complaints and complete discharge prescriptions (81). In high-risk situations, fewer students felt comfortable with prescribing: only 54 felt sufficiently confident to prescribe warfarin and 66 felt confident enough to order i.v. fluids. Many felt support such as guidelines was available (87) and that, if in doubt, they could clarify instructions and seek advice. Students were aware of errors occurring within the medication system; however, most (99) believed that the medicines they prescribed would be safely administered. There was a mixed perception of medication errors: 40 felt that their prescribing errors would not be dealt with constructively and 79 indicated that a culture existed at their hospitals where clinicians would be blamed if they made a prescribing error. Conclusions, At the end of medical school education and prior to assuming responsibility for prescribing, students felt unprepared and perceived that negative outcomes would result if they were involved in errors. These findings indicate that much more work is needed to prepare doctors to prescribe safely, improve the safety of prescribing systems and address the issue of blame. [source]

A dictation system for reporting prescribing errors in community pharmacies

INTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 1 2004
Amanda G. Kennedy assistant professor of medicine
ABSTRACT Objective To pilot and evaluate dictation as a novel method of reporting prescribing errors in community pharmacies. Setting Seven community pharmacies in northwestern Vermont. Method An intervention reporting form was developed and implemented in seven community pharmacies. Using a crossover design, pharmacists reported by both dictation and paper methods for six weeks each. The primary objective was to determine if dictation stimulated more prescribing error reports than a paper-based reporting method. Secondary objectives included a qualitative assessment of dictation feasibility, pharmacist satisfaction with reporting in general, pharmacist preference for a dictation or paper reporting method, and a content description of the prescribing errors reported. Key findings Pharmacists completed a total of 72 reports, describing 80 interventions, during the 12-week study. Thirty-three reports were dictated and 39 were completed on paper (P= 0.56). There were no differences in completeness of reports between paper and dictation (P = 0.62). Seven out of the nine pharmacists (78%) stated they preferred the paper method to dictation. Conclusion Dictation does not appear to increase prescribing error reporting as compared with a paper method. Implementing dictation in community pharmacies proved feasible although most of the pharmacists in this study preferred the paper method. Further investigation to explore dictation as a useful technology in community pharmacies is warranted. [source]

APA national audit of pediatric opioid infusions

PEDIATRIC ANESTHESIA, Issue 2 2010
FFPMRCA, FRCPCH, NEIL S. MORTON MD
Summary Introduction:, A prospective audit of neonates, infants, and children receiving opioid infusion techniques managed by pediatric acute pain teams from across the United Kingdom and Eire was undertaken over a period of 17 months. The aim was to determine the incidence, nature, and severity of serious clinical incidents (SCIs) associated with the techniques of continuous opioid infusion, patient-controlled analgesia, and nurse-controlled analgesia in patients aged 0,18. Methods:, The audit was funded by the Association of Paediatric Anaesthetists (APA) and performed by the acute pain services of 18 centers throughout the United Kingdom. Data were submitted weekly via a web-based return form designed by the Document Capture Company that documented data on all patients receiving opioid infusions and any SCIs. Eight categories of SCI were identified in advance, and the reported SCIs were graded in terms of severity (Grade 1 (death/permanent harm); Grade 2 (harm but full recovery and resulting in termination of the technique or needing significant intervention); Grade 3 (potential but no actual harm). Data were collected over a period of 17 months (25/06/07-25/11/08) and stored on a secure server for analysis. Results:, Forty-six SCIs were reported in 10 726 opioid infusion techniques. One Grade 1 incident (1 : 10 726) of cardiac arrest occurred and was associated with aspiration pneumonitis and the underlying neurological condition, neurocutaneous melanosis. Twenty-eight Grade 2 incidents (1 : 383) were reported of which half were respiratory depression. The seventeen Grade 3 incidents (1 : 631) were all drug errors because of programming or prescribing errors and were all reported by one center. Conclusions:, The overall incidence of 1 : 10 000 of serious harm with opioid infusion techniques in children is comparable to the risks with pediatric epidural infusions and central blocks identified by two recent UK national audits (1,2). Avoidable factors were identified including prescription and pump programming errors, use of concurrent sedatives or opioids by different routes and overgenerous dosing in infants. Early respiratory depression in patients with specific risk factors, such as young age, neurodevelopmental, respiratory, or cardiac comorbidities, who are receiving nurse-controlled analgesia or continuous opioid infusion suggests that closer monitoring for at least 2 h is needed for these cases. As a result of this audit, we can provide parents with better information on relative risks to help the process of informed consent. [source]

Studies suggest risk of bone loss with SSRIs Two cross-sectional studies have suggested the SSRI antidepressants may be associated with an increased risk of bone loss (Arch Intern Med 2007;167:1240,5 &1246,51). In 2722 older women (mean age 79) living in the community who were participating in the Study of Osteoporotic Fractures cohort study, use of SSRIs was associated with a significant increase in the rate of loss of hip bone density compared with nonusers(0.82 vs 0.47 per cent per year). The rate of loss among women taking a tricyclic antidepressant was also 0.47 per cent per year. Excluding women with more severe depression did not alter the findings. In 5995 men aged 65 or older taking an SSRI in another study, mean bone density was 3.9 per cent lower at the hip and 5.9 per cent lower in the lumbar spine compared with no use of antidepressants. Use of a tricyclic antidepressant or trazodone was not associated with increased bone loss. The authors comment that the degree of bone loss is comparable with that associated with corticosteroids. Serotonin transporters have been identified in osteoblasts and osteocytes. Risk of rare birth defects with SSRIs Two US case-control studies have found qualified evidence that use of SSRIs during the first trimester may be associated with a small increase in the risk of rare neonatal defects (N Engl J Med 2007;356:2675,83 & 2684,92). The Slone Epidemiology Center Birth Defects Study identified 9849 infants with birth defects and 5860 without and found no significant association between SSRI use overall and defects previously attributed to SSRIs (craniosynostosis, omphalocele or heart defects). There was some evidence that sertraline and paroxetine may cause specific defects, but this was based on few cases and the absolute risk remained low. The National Birth Defects Prevention Study identified 9622 infants with major birth defects and 4092 controls. There was no significant association with heart defects but the odds of anencephaly, craniosynostosis and omphalocele were each significantly increased by a factor of 2,3. The authors say the absolute risk remains small and their findings require confirmation. UK data do not support MI link with rosiglitazone An interim analysis of a UK clinical trial of rosiglitazone (Avandia) has found no evidence that it is associated with an increased risk of myocardial infarction (N Eng J Med 2007;357:28,38). A US meta-analysis (N Engl J Med 2007;356:2457,71) recently suggested that the odds of an MI or cardiovascular (CV) death in patients taking rosiglitazone were increased by 40,60 per cent compared with controls. The UK analysis of an ongoing nonblinded trial comparing rosiglitazone plus a sulphonylurea or metformin with sulphonylurea/metformin found no significant differences in the risk of MI or CV death. The risk of heart failure was doubled in patients taking rosiglitazone. The authors comment that, with a mean follow-up of 3.75 years, they had too few data to reach a conclusive finding. Switch piroxicam users to another NSAID The European Medicines Agency has advised prescribers to switch patients who are taking oral piroxicam to another NSAID. The advice follows a reappraisal of the safety of piroxicam when the 2006 review of all nonselective NSAIDs suggested it may be associated with increased risks of GI adverse effects and serious skin reactions. The advice does not apply to topical formulations. Piroxicam should not be prescribed for acute conditions and should not be first-choice for osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. The maximum dose should be 20mg per day and treatment should be reviewed after 14 days. The MHRA states there is no need for urgent action; long-term treatment should be reviewed at the next routine appointment. OTC azithromycin? The MHRA is consulting on a request by a pharmaceutical company to reschedule azithromycin to pharmacy-only status for the treatment of known or suspected Chlamydia trachomatis infection in individuals aged 16 years or older. The applicant envisages supplies being made only when a nucleic acid amplification test (NAAT) is positive. Responses should be submitted to the MHRA (www.mhra.gov.uk) by 2 August. Computers can reduce prescribing errors Computerised prescribing reduces by two-thirds the rate of medication errors associated with handwritten prescriptions, a new review has found (Health Services Research 2007; online doi:10.1111/j.1475,6773. 2007.00751.x). There was some evidence that the risk of all errors, dose errors and adverse effects were reduced by computerisation. The greatest impact was seen in settings with very high error rates (>12 per cent) associated with handwritten prescriptions. However, the studies included produced heterogeneous results and the reduction in errors in prescribing for children was not statistically significant. Furthermore, computerisation did not reduce the rate of prescribing the wrong drug. Echinacea works for colds, new study finds The herbal remedy Echinacea does reduce the risk of catching a cold, according to a new metaanalysis (Lancet Infect Dis 2007;7:473,80). In 2006, a Cochrane review found insufficient evidence to support the benefits claimed for Echinacea. The new study, which additionally included experimentally-induced infections among the 14 trials analysed, found that Echinacea reduced the odds of catching a cold by about half and reduced the average duration of a cold by 1.4 days. Though inconclusive, the possibility of publication bias and heterogeneity between the trials could not be excluded. HRT may reduce cardiovascular risk after all A subgroup analysis of the Women's Health Initiative (WHI) suggests that HRT may reduce the risk of coronary heart disease if started soon after the menopause (N Engl J Med 2007;356:2591,602). The main analysis of WHI showed no cardiovascular benefit for HRT, a finding attributed to the relatively old mean age of participants (59). In the new analysis of 1064 women aged 50,59, HRT use was associated with a significant reduction in coronary artery calcification compared with nonuse, with greater effect associated with greater adherence. Reducing BP key to avoiding heart failure An angiotensin,II receptor blocker (ARB) is no better than other antihypertensives at avoiding the development of heart failure in individuals with hypertension, say US investigators (Lancet 2007;369:2079,87). Drugs that affect the renin-angiotensin system can reduce ventricular hypertrophy and may therefore prevent the development of heart failure in patients with hypertension. This study found similar improvements in diastolic function in 384 patients with hypertension and left ventricular dysfunction randomised to valsartan (Diovan) or placebo in addition to standard antihypertensive treatment for 38 weeks. The authors conclude that blood pressure reduction, not choice of drug, is the most important factor. Copyright © 2007 Wiley Interface Ltd [source]

Clinical trials flatter anti-TNFs in RA The efficacy of anti-TNF agents in clinical trials is not matched by experience in daily practice in patients with rheumatoid arthritis, say Dutch investigators (Ann Rheum Dis online: 10 April 2007; doi:10.1136/ard.2007.072447). They compared outcomes from a systematic review of trials of etanercept (Enbrel), infliximab (Remicade) and adalimumab (Humira) and a national postmarketing surveillance scheme (DREAM). In 5 of 11 comparisons, the response rate in DREAM was significantly lower than that in RCTs. Responses among DREAM patients who met the inclusion criteria for clinical trials were significantly greater than among noneligible patients and comparable with those of patients participating in the trials. The authors conclude that patients in trials have more severe disease and therefore a response to treatment that is not matched in daily practice. Methadone prescriptions double in 10 years Methadone treatment for opiate addicts has more than doubled in the past 10 years, according to an audit of opiate substitution in England by the National Treatment Agency for Substance Misuse (www.nta.nhs.uk). The total number of methadone prescriptions increased from 970 900 in 1995 to over 1.8 million in 2004. The introduction of buprenorphine (Subutex) has not reduced methadone prescribing , 96 per cent of responding centres prescribed methadone and 88 per cent prescribed buprenorphine. Seventy-two per cent of centres prescribe benzodiazepines to opiate addicts, causing the NTA some concern. GPs were involved in prescribing management in about 60 per cent of centres. Next NICE guidelines The Department of Health has referred eight topics to NICE for the development of clinical guidelines: preventing venous thromboembolism, acute coronary syndromes, chest pain, social complications during pregnancy (eg drug misuse), benign prostatic hyperplasia, constipation in children, neonatal jaundice and metastatic disease of unknown primary origin. Errors with children , Every step of drug treatment for children, from prescribing to writing notes, is associated with a substantial level of error, say US investigators (Quality and Safety in Health Care 2007;16:116-26). Their systematic review of 31 studies reporting medication errors in paediatrics found that 3-37 per cent were associated with prescribing errors, 5-58 per cent with dispensing errors, 72-75 per cent with errors of administration, and 17-21 per cent with documentation errors. Suggestions for remedial strategies were not evidence based, the authors found. , and transplant patients Errors in medication are common among outpatients who have received liver, kidney or pancreas transplants, a second US study has found (Arch Surg 2007;142:278-83). Twelve months' follow-up of 93 patients revealed a total of 149 errors of drug treatment, with a frequency of 15 in 219 visits over a four-week period. One-third of errors were associated with adverse events including hospital admission and graft rejection. Patients were taking an average of 11 medicines; analysis showed that over half of errors originated with the patients and 13 per cent were associated with prescribing. Paracetamol pack benefit challenged A new study has challenged accepted wisdom that reducing the OTC pack size of paracetamol cut the suicide rate (PLoS Medicine 2007;4:e105). In 1998, pack sizes of paracetamol were limited to 16 in general sale outlets and 32 in pharmacies. Suicide rates subsequently decreased but, though widely assumed, a causal link has not been established. Researchers from London and the Office of National Statistics have now examined mortality trends from suicide associated with antidepressants, aspirin, compound paracetamol preparations and nondrug poisoning. They found that all fatal suicides declined at similar rates after the pack size reductions. While not excluding the possibility that restricting easy access to paracetamol may have helped, these data suggest that other factors were also important. CV risk with ibuprofen among aspirin users Ibuprofen, but not naproxen, is associated with a higher risk of cardiovascular events and heart failure than lumiracoxib (Prexige) in high-risk patients, according to a new analysis of the TARGET trial (Ann Rheum Dis online: 5 April 2007; doi:10.1136/ard.2006.066001). TARGET comprised two studies comparing naproxen or ibuprofen with lumiracoxib in a total of 18 325 patients with OA. This post-hoc analysis stratified patients by their cardiovascular risk; the primary end-point was a composite of cardiovascular mortality, nonfatal myocardial infarction and stroke at one year. Among those at high risk who were taking aspirin, ibuprofen was associated with an increased risk of the composite end-point compared with lumiracoxib (2.14 vs 0.25 per cent). The risk was similar for naproxen and lumiracoxib (1.58 vs 1.48 per cent). In high-risk patients not taking aspirin, the risk was similar for ibuprofen and lumiracoxib, but lower for naproxen than lumiracoxib. Congestive heart failure was more common in patients taking ibuprofen than lumiracoxib (1.28 vs 0.14 per cent); the risk was similar with naproxen and lumiracoxib. The authors emphasise that their findings should be considered hypothesis-generating. CVD guidelines criticised The second edition of the guidelines of the Joint British Societies on preventing cardiovascular disease have been harshly criticised for failing to meet international quality standards (Int J Clin Pract online doi: 10.1111/j.1742-1241.2007.01310.x). Kent GP Dr Rubin Minhas evaluated the guidelines against the criteria of the Appraisal of Guidelines and Research (AGREE) Collaboration. He identified areas of weakness including stakeholder involvement, rigour of development, applicability (by not considering cost) and editorial independence from the pharmaceutical industry. The guidelines should not be recommended for clinical practice, he concludes. OTC naproxen? The MHRA is consulting on switching naproxen 250mg to pharmacy-only status for the treatment of period pain in women aged 15-50. The change would offer an alternative to ibuprofen, currently the only other OTC medicine with this indication. Responses should be submitted by 23 May. The Agency is currently considering responses to its consultation on switching tranexamic acid to OTC status for heavy menstrual bleeding. Diabetes costs The total cost of prescribing for diabetes in England has doubled in only five years, official statistics show. The NHS Information Centre (www.ic.nhs.uk) report shows that spending in primary and secondary care in 2006 was £561 million, up 14 per cent on 2005. Growth was due to increased prescribing of oral hypoglycaemic agents (notably the glitazones , up by one-third over 2005) and the higher costs of insulins. Pharmacists may give flu jabs PCTs may consider using pharmacists to administer flu vaccines to some at-risk groups in the 2007/08 season, according to Department of Health plans. Flu vaccination payment for patients with diabetes, coronary heart disease, and stroke and TIA is provided under the Quality Outcomes Framework. The Department suggests that PCTs consider contracting a local enhanced service from pharmacists to reach other patients at increased risk, such as those with chronic liver disease, multiple sclerosis and related conditions, hereditary and degenerative disease of the CNS and carers.

Discrepancies between GPs' and psychiatrists' medication records

PROGRESS IN NEUROLOGY AND PSYCHIATRY, Issue 6 2008
Julie Robinson MRCPsych
Clear communication between primary and secondary care is essential to prevent prescribing errors, especially in the case of psychiatry where medication is frequently altered and prescribing may be the responsibility of either the GP or the specialist. Here, Dr Robinson describes an audit carried out at the local elderly day treatment service to examine the discrepancies between GPs' records of medication and those of the day service, and to investigate how improvements could be made.
