Computerized clinical decision support for prescribing: provision does not guarantee uptake

Annette J Moxey; Jane Robertson; David Newby; Isla M. Hains; Margaret Williamson; Sallie-Anne Pearson

There is wide variability in the use and adoption of recommendations generated by computerized clinical decision support systems (CDSSs) despite the benefits they may bring to clinical practice. We conducted a systematic review to explore the barriers to, and facilitators of, CDSS uptake by physicians to guide prescribing decisions. We identified 58 studies by searching electronic databases (1990-2007). Factors impacting on CDSS use included: the availability of hardware, technical support and training; integration of the system into workflows; and the relevance and timeliness of the clinical messages. Further, systems that were endorsed by colleagues, minimized perceived threats to professional autonomy, and did not compromise doctor-patient interactions were accepted by users. Despite advances in technology and CDSS sophistication, most factors were consistently reported over time and across ambulatory and institutional settings. Such factors must be addressed when deploying CDSSs so that improvements in uptake, practice and patient outcomes may be achieved.

BackgroundComputerised clinical decision support systems (CDSSs) are used widely to improve quality of care and patient outcomes. This systematic review evaluated the impact of CDSSs in targeting specific aspects of prescribing, namely initiating, monitoring and stopping therapy. We also examined the influence of clinical setting (institutional vs ambulatory care), system- or user-initiation of CDSS, multi-faceted vs stand alone CDSS interventions and clinical target on practice changes in line with the intent of the CDSS.MethodsWe searched Medline, Embase and PsychINFO for publications from 1990-2007 detailing CDSS prescribing interventions. Pairs of independent reviewers extracted the key features and prescribing outcomes of methodologically adequate studies (experiments and strong quasi-experiments).Results56 studies met our inclusion criteria, 38 addressing initiating, 23 monitoring and three stopping therapy. At the time of initiating therapy, CDSSs appear to be somewhat more effective after, rather than before, drug selection has occurred (7/12 versus 12/26 studies reporting statistically significant improvements in favour of CDSSs on = 50% of prescribing outcomes reported). CDSSs also appeared to be effective for monitoring therapy, particularly using laboratory test reminders (4/7 studies reporting significant improvements in favour of CDSSs on the majority of prescribing outcomes). None of the studies addressing stopping therapy demonstrated impacts in favour of CDSSs over comparators. The most consistently effective approaches used system-initiated advice to fine-tune existing therapy by making recommendations to improve patient safety, adjust the dose, duration or form of prescribed drugs or increase the laboratory testing rates for patients on long-term therapy. CDSSs appeared to perform better in institutional compared to ambulatory settings and when decision support was initiated automatically by the system as opposed to user initiation. CDSSs implemented with other strategies such as education were no more successful in improving prescribing than stand alone interventions. Cardiovascular disease was the most studied clinical target but few studies demonstrated significant improvements on the majority of prescribing outcomes.ConclusionOur understanding of CDSS impacts on specific aspects of the prescribing process remains relatively limited. Future implementation should build on effective approaches including the use of system-initiated advice to address safety issues and improve the monitoring of therapy.

BackgroundManaged care organizations use a variety of strategies to reduce the cost and improve the quality of medication use. The effectiveness of such policies is not well understood. The objective of this research was to update a previous systematic review of interventions, published between 1966 and 2001, to improve the quality and efficiency of medication use in the US managed care setting.MethodsWe searched MEDLINE and EMBASE for publications from July 2001 to January 2007 describing interventions targeting drug use conducted in the US managed care setting. We categorized studies by intervention type and adequacy of research design using commonly accepted criteria. We summarized the outcomes of well-controlled strategies and documented the significance and magnitude of effects for key study outcomes.ResultsWe identified 164 papers published during the six-year period. Predominant strategies were: educational interventions (n = 20, including dissemination of educational materials, and group or one-to-one educational outreach); monitoring and feedback (n = 22, including audit/feedback and computerized monitoring); formulary interventions (n = 66, including tiered formulary and patient copayment); collaborative care involving pharmacists (n = 15); and disease management with pharmacotherapy as a primary focus (n = 41, including care for depression, asthma, and peptic ulcer disease). Overall, 51 studies met minimum criteria for methodological adequacy. Effective interventions included one-to-one academic detailing, computerized alerts and reminders, pharmacist-led collaborative care, and multifaceted disease management. Further, changes in formulary tier-design and related increases in copayments were associated with reductions in medication use and increased out-of-pocket spending by patients. The dissemination of educational materials alone had little or no impact, while the impact of group education was inconclusive.ConclusionThere is good evidence for the effectiveness of several strategies in changing drug use in the managed care environment. However, little is known about the cost-effectiveness of these interventions. Computerized alerts showed promise in improving short-term outcomes but little is known about longer-term outcomes. Few well-designed, published studies have assessed the potential negative clinical effects of formulary-related interventions despite their widespread use. However, some evidence suggests increases in cost sharing reduce access to essential medicines for chronic illness.

An overview of the patterns of prescription opioid use, costs and related harms in Australia

Bianca Blanch; Sallie-Anne Pearson; Paul S. Haber

AIMS To report Australian population trends in subsidized prescribed opioid use, total costs to the Australian government to subsidize these medicines and opioid-related harms based on hospitalizations and accidental poisoning deaths. METHODS We utilized three national aggregated data sources including dispensing claims from the Pharmaceutical Benefits Scheme, opioid-related hospitalizations from the National Hospital Morbidity Database and accidental poisoning deaths from the Australian Bureau of Statistics. RESULTS Between 1992 and 2012, opioid dispensing episodes increased 15-fold (500 000 to 7.5 million) and the corresponding cost to the Australian government increased 32-fold (

271 million). Opioid-related harms also increased. Opioid-related hospitalizations increased from 605 to 1464 cases (1998-2009), outnumbering hospitalizations due to heroin poisonings since 2001. Deaths due to accidental poisoning (pharmaceutical opioids and illicit substances combined) increased from 151 to 266 (2002-2011), resulting in a rise in the death rate of 0.78 to 1.19 deaths/100 000 population over 10 years. Death rates increased 1.8 fold in males and 1.4 fold in females. CONCLUSIONS The striking increase in opioid use and related harms in Australia is consistent with trends observed in other jurisdictions. Further, there is no evidence to suggest these increases are plateauing. There is currently limited evidence in Australia about individual patterns of opioid use and the associated risk of adverse events. Further research should focus on these important issues so as to provide important evidence supporting effective change in policy and practice.

The influence of admissions variables on first year medical school performance: a study from Newcastle University, Australia

Frances Kay-Lambkin; Sallie-Anne Pearson; Isobel Rolfe

Appropriate selection of medical students is a fundamental prerequisite if medical schools are to produce competent and caring doctors. The selection criteria for entry to the medical degree course at the University of Newcastle, New South Wales, are unique in Australia. The purpose of this study was to identify admission criteria that may predict performance in the first postgraduate (intern) year. Performance ratings were obtained from the clinical supervisors of two graduating classes of Newcastle University medical students during their five terms in internship (first postgraduate year). At least one rating was obtained for 93% of interns. A subset analysis of interns with multiple ratings (57%) showed that combining previous study in both humanities and science before medical school entry was predictive of higher intern performance ratings. These interns were rated more favourably than those who had studied science alone. Moreover, students who had earlier studied both humanities and science were twice as likely to complete their medical degree as those who had studied science alone. Age, gender, admission interview results, written psychometric test scores, academic marks, and whether previous tertiary study had been undertaken prior to medical school entry were not predictive of intern performance ratings. Subject spread, including a background in humanities, is important for effective medical practice, at least in the immediate postgraduate period. Perhaps it is time to evaluate the admission criteria by which medical students are selected.

BACKGROUND The addition of HER2-targeted agents to standard treatment has been shown to improve outcomes for HER2 positive metastatic breast cancer patients. We undertook a meta-analysis to evaluate the efficacy of HER2-targeted therapy in addition to standard treatment in metastatic breast cancer patients. PATIENTS AND METHODS Eligible trials were randomised controlled trials (RCTs) comparing the addition of HER2 therapy to standard treatment (hormone or chemotherapy) reporting overall survival (OS), time to progression (TTP), progression-free survival (PFS) and/or response rates. RESULTS Eight trials comprising 1848 patients were eligible for inclusion. HER2-targeted agents were trastuzumab and lapatinib and therapeutic partners were taxanes (4 RCTs), anthracyclines (1), capecitabine (2), anastrozole (1) and letrozole (1). The addition of HER2-targeted agents improved OS [hazard ratios (HR) 0.78; 95% confidence interval (CI) 0.67-0.91], TTP (HR 0.56; 95% CI 0.48-0.64), PFS (HR 0.63; 95% CI 0.53-0.74) and overall response rate (relative risk 1.67; 95% CI 1.46-1.90). CONCLUSIONS Our meta-analysis confirms the benefit of adding HER2-targeted therapy to standard treatment in HER2 positive metastatic breast cancer. Compared with OS, TTP, PFS and ORR overestimate treatment benefit. Trials in our meta-analysis differed in terms of partner drug or HER2 agents, yet delivered comparable outcomes.
