Medication reconciliation during internal hospital transfer and impact of computerized prescriber order entry.

BACKGROUND: Internal hospital transfer is a vulnerable time during which patients are at high risk of medication discrepancies that can result in clinically significant harm, medication errors, and adverse drug events. OBJECTIVE: To identify, characterize, and assess the clinical impact of unintentional medication discrepancies during internal hospital transfer and to investigate the influence of computerized prescriber order entry (CPOE) on medication discrepancies. METHODS: All patients transferred between 10 inpatient units at 2 tertiary care hospitals were prospectively assessed to identify discrepancies. Interfaces included transfers between (1) units that both used paper-based medication ordering systems; (2) units that both used CPOE-based systems; and (3) units that used both paper-based and CPOE-based systems (hybrid transfer). The primary endpoint was the number of patients with at least 1 unintentional medication discrepancy during internal hospital transfer. Discrepancies were identified through assessment and comparison of a best possible medication transfer list with the actual transfer orders. A multidisciplinary team of clinicians assessed the potential clinical impact and severity of unintentional discrepancies. RESULTS: Overall, 190 patients were screened and 129 patients were included. Eighty patients (62.0%) had at least 1 unintentional medication discrepancy at the time of transfer, and the most common discrepancy was medication omission (55.6%). Factors that independently increased the risk of a patient experiencing at least 1 unintentional discrepancy included lack of best possible medication history, increasing number of home medications, and increasing number of transfer medications. Forty-seven patients (36.4%) had at least 1 unintentional discrepancy with the potential to cause discomfort and/or clinical deterioration. The risk of discrepancies was present regardless of the medication-ordering system (paper, CPOE, or hybrid). CONCLUSIONS: Clinically significant medication discrepancies occur commonly during internal hospital transfer. A structured, collaborative, and clearly defined medication reconciliation process is needed to prevent internal transfer discrepancies and patient harm.

From pharmaco-therapy to pharmaco-prevention: trends in prescribing to older adults in Ontario, Canada, 1997-2006.

BACKGROUND: The developed world is undergoing a demographic transition with greater numbers of older adults and higher rates of chronic disease. Most elder care is now provided by primary care physicians, who prescribe the majority of medications taken by these patients. Despite these significant trends, little is known about population-level prescribing patterns to primary care patients aged 65+. METHODS: We conducted a population-based retrospective cohort study to examine 10-year prescribing trends among family physicians providing care to patients aged 65+ in Ontario, Canada. RESULTS: Both crude number of prescription claims and prescription rates (i.e., claims per person) increased dramatically over the 10-year study period. The greatest change was in prescribing patterns for females aged 85+. Dramatic increases were observed in the prescribing of preventive medications, such as those to prevent osteoporosis (+2,347%) and lipid-lowering agents (+697%). And lastly, the number of unique classes of medications prescribed to older persons has increased, with the proportion of older patients prescribed more than 10 classes of medications almost tripling during the study period. CONCLUSIONS: Prescribing to older adults by family physicians increased substantially during the study period. This raises important concerns regarding quality of care, patient safety, and cost sustainability. It is evident that further research is urgently needed on the health outcomes (both beneficial and harmful) associated with these dramatic increases in prescribing rates.

Medication reconciliation at hospital discharge: evaluating discrepancies.

BACKGROUND: Hospital discharge is an interface of care when patients are at a high risk of medication discrepancies as they transition from hospital to home. These discrepancies are important, as they may contribute to drug-related problems, medication errors, and adverse drug events. OBJECTIVE: To identify, characterize, and assess the clinical impact of unintentional medication discrepancies at hospital discharge. METHODS: All consecutive general internal medicine patients admitted for at least 72 hours to a tertiary care teaching hospital were prospectively assessed. Patients were excluded if they were discharged with verbal prescriptions; died during hospitalization; or transferred from or to a nursing home, another institution, or another unit within the same hospital. The primary endpoint was to determine the number of patients with at least one unintended medication discrepancy on hospital discharge. Medication discrepancies were assessed through comparison of a best possible medication discharge list with the actual discharge prescriptions. Secondary objectives were to characterize and assess the potential clinical impact of the unintentional discrepancies. RESULTS: From March 14, 2006, to June 2, 2006, 430 patients were screened for eligibility; 150 patients were included in the study. Overall, 106 (70.7%) patients had at least one actual or potential unintentional discrepancy. Sixty-two patients (41.3%) had at least one actual unintentional medication discrepancy at hospital discharge and 83 patients (55.3%) had at least one potential unintentional discrepancy. The most common unintentional discrepancies were an incomplete prescription requiring clarification, which could result in a patient delay in obtaining medications (49.5%), and the omission of medications (22.9%). Of the 105 unintentional discrepancies, 31(29.5%) had the potential to cause possible or probable patient discomfort and/or clinical deterioration. CONCLUSIONS: Medication discrepancies occur commonly on hospital discharge. Understanding the type and frequency of discrepancies can help clinicians better understand ways to prevent them. Structured medication reconciliation may help to prevent discharge medication discrepancies.

Sensitivity of patient outcomes to pharmacist interventions. Part III: systematic review and meta-analysis in hyperlipidemia management.

BACKGROUND: Hyperlipidemia increases the risk of cardiovascular diseases, and control is pivotal for preventing disease complications. Multidisciplinary interventions, including those performed by pharmacists, are important for improving patients' outcomes. OBJECTIVE: To quantify the impact of pharmacist interventions in enhancing patients' outcomes. METHODS: Two reviewers searched International Pharmaceutical Abstracts, MEDLINE, EMBASE, The Cochrane Central Register of Controlled Trials, 3rd Quarter, and Cumulative Index to Nursing and Allied Health Literature (all from inception to July 2007) for pharmacist interventions in hyperlipidemia. Quality was assessed using the Downs-Black scale. Data extracted included the number of patients enrolled; study characteristics; intervention type; and pre- and postintervention measures for low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, total cholesterol, adherence, and quality of life. A random effects meta-analysis combined data. Heterogeneity of effects was tested using chi(2) analysis. Publication bias was assessed using funnel plots and the Begg-Mazumdar statistic. RESULTS: Forty-eight studies were found; 23 met inclusion criteria. Study settings included medical clinic/center (n = 12), community pharmacy (n = 8), hospital (n = 2), and patient homes (n = 1). Article quality was good (71% +/- 7.0%). Patient education (78%) and medication management (74%) were the most common interventions. Total cholesterol was significantly reduced from baseline (mean +/- SD; 34.3 +/- 10.3 mg/dL; p < 0.001) and above that for controls (22.0 +/- 10.4 mg/dL; p = 0.034). LDL-C was reduced significantly from baseline (32.6 +/- 11.3 mg/dL; p = 0.004), but not significantly more than controls (17.5 +/- 10.9 mg/dL; p = 0.109). A clinically relevant but not statistically significant reduction in triglycerides was found. No impact on HDL-C levels was found. Patients' adherence to pharmacotherapeutic regimens and quality of life were considered possibly not sensitive and possibly sensitive to pharmacist interventions, respectively. CONCLUSIONS: Total cholesterol is sensitive to pharmacist interventions, while LDL-C and triglyceride levels are possibly sensitive to those interventions. Further research is required for these outcomes.

Pharmacist medication assessments in a surgical preadmission clinic.

BACKGROUND: In the hospital setting, postoperative admission is a key vulnerable moment when patients are at increased risk of medication discrepancies. This study measures the reduction of medication discrepancies associated with a combined intervention of structured pharmacist medication history interviews with assessments in a surgical preadmission clinic and a postoperative medication order form. METHODS: In the Surgical Pharmacist in Preadmission Clinic Evaluation (SPPACE) study, patients who had a preadmission clinic appointment before undergoing surgical procedures were eligible for inclusion. Patients were excluded if they were scheduled for discharge the same day as their surgery. Eligible patients were randomly assigned to the intervention arm (structured pharmacist medication history interview with assessment and generation of a postoperative medication order form) or to the standard care arm (nurse-conducted medication histories and surgeon-generated medication orders). The primary end point was the number of patients with at least 1 postoperative medication discrepancy related to home medications. RESULTS: Between April 19, 2005, and June 3, 2005, a total of 464 patients were enrolled in the study, of which 227 and 237 patients were randomized to the intervention and standard care arms, respectively. In the intervention arm, 41 (20.3%) of 202 patients had at least 1 postoperative medication discrepancy related to home medications, compared with 86 (40.2%) of 214 patients in the standard care arm (P<.001). In the intervention arm, 26 (12.9%) of 202 patients had at least 1 postoperative medication discrepancy with the potential to cause possible or probable harm, compared with 64 (29.9%) of 214 patients in the standard care arm (P<.001). These were mostly omissions of reordering home medications. CONCLUSION: A combined intervention of pharmacist medication assessments and a postoperative medication order form can reduce postoperative medication discrepancies related to home medications.

The EMITT study: development and evaluation of a medication information transfer tool.

BACKGROUND: Continuity of care is required as patients move from the care of one pharmacist to another. The appropriate transfer of medication information between pharmacists as well as to patients at these times is essential in order to prevent drug-related problems (DRPs). OBJECTIVE: To develop a tool to transfer medication information between various pharmacists caring for the same patients. Secondary objectives were to evaluate the tool based on utility in practice and satisfaction of pharmacists. METHODS: The project consisted of a needs assessment involving in-depth interviews with patients and pharmacists and a literature review. These data were used to develop an optimal tool for medication information transfer between pharmacists in different practice settings. The tool was evaluated in a feasibility pilot for potential utility and pharmacist satisfaction. RESULTS: The tool created called EMITT (electronic medication information transfer tool) facilitates the communication of information to outpatient pharmacists including a letter and an up-to-date list of the patient's drugs. A total of 187 medication issues were communicated within 40 transferred letters, 61 of which required active follow-up, which potentially prevented 348 DRPs if the receiver of the information acted on the information that was provided. The 3 most common issues that required follow-up were restarting a held medication (n = 13), adjustment of doses based on laboratory results (n = 11), and starting a new indicated medication in the future (n = 7). CONCLUSIONS: A tool can be created to help address the gap in communication between pharmacists when patients move between interfaces of care by evaluating the needs of healthcare professionals involved in the information transfer process. It is envisioned that the elements of our tool can be easily adapted to other institutions to improve medication information transfer.

Drug-related problems on hospital admission: relationship to medication information transfer.

BACKGROUND: Patients with end-stage renal disease (ESRD) are at risk for drug-related problems (DRPs), especially on hospital admission. OBJECTIVE: To identify and characterize the DRPs experienced by patients with ESRD on admission and investigate how these DRPs could be related to gaps in medication information transfer. METHODS: Patients with ESRD admitted to the hospital were prospectively identified and clinically assessed by a pharmacist to identify and categorize DRPs on admission. Each DRP was evaluated to determine whether it could have been caused by a gap in medication information transfer. For DRPs caused in this manner, the interface in the information transfer process where the gap may have occurred was determined. RESULTS: A total of 199 DRPs were identified in 47 patients with ESRD over a 12 week period. Ninety-two percent of patients had at least one DRP on admission, with an average of 4.2 +/- 2.2 DRPs per patient. The most common DRP identified was indication for drug therapy--patient requires drug but is not receiving it (51.3%). Of the total DRPs, 130 (65%) were related to gaps in medication information transfer, with 21.5% occurring between the inpatient hospital and the ambulatory clinic pharmacists and 17.7% between the admitting physician and the patient. CONCLUSIONS: Results of this study demonstrate that, in patients with ESRD, DRPs on admission are frequently related to gaps in medication information transfer between healthcare professionals and also between healthcare providers and patients. Improved communication is required at medication information transfer interfaces to prevent these DRPs.

Collaborative medication management in a team-based primary care practice: an explanatory conceptual framework.

BACKGROUND: In ambulatory practice many different health care professionals are involved in the drug use process. The roles and functions of these individuals can be difficult to define, because of a lack of a common ground for discussion. Deliberating the topic is important for developing a team approach to medication management. OBJECTIVE: To describe a conceptual framework to create a platform that can be used by different health care providers to identify, define, and discuss roles and responsibilities in collaborative medication management. METHODS: Authors reviewed and reflected upon their experiences as practitioners in implementing a pharmaceutical care-based consulting practice within a family medicine practice setting. Key roles and responsibilities relative to collaborative management of medications were identified and described. RESULTS: A conceptual framework subsequently developed, the Team Approach to Medication Management, consists of 3 primary components referred to as medication-related practices (medication prescribing, medication taking, and medication dispensing). Each of these primary practices is supported by a team of health care professionals who have supportive roles and responsibilities. In the Team Approach to Medication Management framework, the patient's medication-taking practice holds a central and key position within a collaborative approach to medication management. CONCLUSIONS: The proposed Team Approach to Medication Management framework can be used to guide discussions and decisions among the different health care providers working in primary care to define both direct and indirect roles that health care practitioners and patients play in collaborative medication management.
