Computerized physician order entry system combined with on-ward pharmacist: analysis of pharmacists' interventions

Rationale, aims and objectives To analyse pharmacists' interventions in a setting where a computerized physician order entry system (CPOE) is in use and a pharmacist works on the ward. Method A prospective cohort study was conducted in seven wards of a French teaching hospital using CPOE along with the presence of a full‐time on‐ward pharmacy resident. We documented the characteristics of pharmacists' interventions communicated to physicians during the medication order validation process whenever a drug‐related problem was identified. Independent predictors of the physician's acceptance of the pharmacist's intervention were assessed using multiple logistic regression analysis. Results The 448 pharmacists' interventions concerned: non‐conformity to guidelines or contraindications (22%), too high doses (19%), drug interactions (15%) and improper administration (15%). The interventions consisted of changes in drug choice (41%), dose adjustment (23%), drug monitoring (19%) and optimization of administration (17%). Interventions were communicated via the CPOE in 57% of cases and 43% orally. The rate of physicians' acceptance was 79.2%. In multivariate analysis, acceptance was significantly associated with the physician's status [higher for residents vs. seniors: OR = 7.23, CI 95 (2.37–22.10), P < 0.01], method of communication [higher for oral vs. computer communication: OR = 12.5, CI 95 (4.16–37.57), P < 0.01] and type of recommendation [higher for drug monitoring vs. drug choice recommendations: OR = 10.32, CI 95 (3.20–33.29), P < 0.01]. Conclusions When a clinical pharmacist is present on a ward in which a CPOE is in use, the pharmacists' interventions are well accepted by physicians. Specific predictors of the acceptance by physicians emerge, but further research as to the impact of CPOE on pharmacist–physician communication is needed.     

Impact of the clinical pharmacist on readmission in patients with acute coronary syndrome

BACKGROUND: Previous studies have reported a positive impact of pharmacists on care of patients with chronic illnesses. The impact of the clinical pharmacist on hospital readmission in patients with acute coronary syndromes (ACS) has yet to be evaluated, as of this writing. OBJECTIVE: To evaluate the impact of the clinical pharmacist as a direct patient-care team member on cardiac-related readmission in patients admitted to the general cardiology unit with ACS. METHODS: A prospective, nonrandomized observational study compared patients who received standard practice care with patients admitted to a service with a clinical pharmacist to provide care at the bedside. Patients admitted to and discharged from the general cardiology unit for ACS were included. The primary endpoint of the study was cardiac-related readmission at 30 days following hospital discharge. Secondary endpoints included length of stay and medication utilization. Interventions provided by the clinical pharmacist in the study group were documented. RESULTS: Cardiac readmission at 30 days was similar between the groups (p = 0.59). In the subset of patients with unstable angina, readmission in the study group was significantly lower than in the control group (1.3% vs 9.1%; p = 0.04). Patients in both groups were similarly managed using drug therapy and invasive coronary interventions. The medical staff's rate of acceptance of recommendations provided by the pharmacist was 94.4%. The most common interventions were medication education and identification of indicated therapy. CONCLUSIONS: The addition of pharmacists did not decrease readmission in patients with ACS. The finding of significant reduction in readmission in the subset of patients with unstable angina should be considered "hypothesis generating" for future randomized studies to confirm the results.     

Factors associated with clinical assessment of overactive bladder and selection of treatment

BACKGROUND: Overactive bladder (OAB) affects >17 million individuals in the United States, but the symptoms of OAB are frequently underreported by patients and therefore untreated by physicians. OBJECTIVE: The purpose of this observational study was to investigate the demographic and clinical factors associated with the decision to treat OAB pharmacologically and identify factors associated with physicians' assessment of symptom severity. METHODS: We studied 31 physicians treating 217 patients with OAB and collected data on patient demographic characteristics, OAB symptoms, previous management strategies, physicians' assessments of OAB severity, and treatment prescribed. Stepwise logistic regression was used to identify factors associated with selecting pharmacologic treatment and with physician assessment of severity of OAB symptoms. RESULTS: The mean age of the patients was 61.3 years; approximately 82% were female, and approximately 73% were white. Participants with urinary incontinence were significantly (P < 0.001) more likely to be treated with medication than were those with only symptoms of nocturia or urinary frequency. Other significant factors associated with pharmacologic treatment were being white (odds ratio [OR], 9.5; 95% CI, 2.9-30.8); being black (OR, 5.9; 95% CI, 1.2-29.7); physician's clinical assessment of OAB as moderate (OR, 3.5; 95% CI, 1.5-8.2) or severe (OR, 3.8; 95% CI, 1.1-13.7); previous use of medication (OR, 2.9; 95% CI, 1.1-8.1); and number of incontinence episodes in the last 24 hours (OR, 1.2; 95% CI, 1.0-1.5). Factors associated with physician assessment of OAB severity included distress due to OAB symptoms (OR, 2.1; 95% CI, 1.3-3.2), number of incontinence episodes in the last 24 hours (OR, 1.2; 95% CI, 1.1-1.4), and use of previous treatment(s) (OR, 0.4; 95% CI, 0.2-0.8). CONCLUSIONS: Both demographic and clinical symptoms of OAB were associated with the decision to treat OAB with medication, whereas physicians' assessment of OAB severity was associated only with clinical symptoms. Urinary incontinence was the key symptom associated with the decision to treat patients with medication and with the assessment of OAB symptom severity.     

Retrospective evaluation of medication appropriateness and clinical pharmacist drug therapy recommendations for home-based primary care veterans

Background:The Medication Appropriateness Index (MAI) has demonstrated reliability in several outpatient settings. Clinical pharmacists play key roles as members of an interdisciplinary team in determining medication appropriateness.Objective:The goal of this study was to examine medication appropriateness using the MAI and the degree of recommendation acceptance associated with clinical pharmacist medication reviews for veterans enrolled in the Home-Based Primary Care (HBPC) program.Methods:A retrospective analysis of clinical pharmacist medication reviews was performed by accessing the computerized patient medical record. Patients included in the study were enrolled in the HBPC program between March 2002 and January 2004. The data were examined to determine a total MAI score associated with medication recommendations after each review. The number and types of pharmacist recommendations, their acceptance rate, and the total number of medications discontinued were also evaluated.Results:Seventy-nine patients (mean [SD] age, 75.3 [10.3] years) identified through the pharmacy database met the inclusion criteria and were included in the study. No patients identified were excluded from the analysis. A statistically significant decrease in the overall MAI score was observed from the initial review to the end of the study (P < 0.001). Recommendations to patients' primary care providers included medication initiation/discontinuation, laboratory monitoring, dosage adjustment, and other issues associated with appropriate prescribing that could be categorized using the MAI. Recommendations to home health nurses included monitoring for medication adherence, efficacy, and adverse events. Pharmacist recommendation acceptance rates for primary care providers and home health nurses were 69% and 56%, respectively. Overall, 121 medications were discontinued during the study period.Conclusions:By using the MAI for evaluation, pharmacist recommendations significantly improved the appropriateness of medication use among veterans receiving home health care. A majority of pharmacist recommendations were accepted.     

Physician Medical Direction andClinical Performance at an Established Emergency Medical Services System

Objective. Few developed emergency medical services (EMS) systems operate without dedicated medical direction. We describe the experience of Hamad Medical Corporation (HMC) EMS, which in 2007 first engaged an EMS medical director to develop andimplement medical direction andquality assurance programs. We report subsequent changes to system performance over time. Methods. Over one year, changes to the service's clinical infrastructure were made: Policies were revised, paramedic scopes of practice were adjusted, evidence-based clinical protocols were developed, andskills maintenance andeducation programs were implemented. Credentialing, physician chart auditing, clinical remediation, andonline medical command/hospital notification systems were introduced. Results. Following these interventions, we report associated improvements to key indicators: Chart reviews revealed significant improvements in clinical quality. A comparison of pre- andpost-intervention audited charts reveals a decrease in cases requiring remediation (11% to 5%, odds ratio [OR] 0.43 [95% confidence interval (CI) 0.20–0.85], p = 0.01). The proportion of charts rated as clinically acceptable rose from 48% to 84% (OR 6 [95% CI 3.9–9.1], p < 0.001). The proportion of misplaced endotracheal tubes fell (3.8% baseline to 0.6%, OR 0.16 [95% CI 0.004–1.06], (exact) p = 0.05), corresponding to improved adherence to an airway placement policy mandating use of airway confirmation devices andsecuring devices (0.7% compliance to 98%, OR 714 [95% CI 64–29,334], (exact) p < 0.001). Intravenous catheter insertion in unstable cases increased from 67% of cases to 92% (OR 1.31 [95% CI 1.09–1.71], p = 0.004). EMS administration of aspirin to patients with suspected ischemic chest pain improved from 2% to 77% (OR 178 [95% CI 35–1,604], p < 0.001). Conclusions. We suggest that implementation of a physician medical direction is associated with improved clinical indicators andoverall quality of care at an established EMS system     

A retrospective study of drug‐related problems in Australian aged care homes: medication reviews involving pharmacists and general practitioners

Background Drug‐related problems (DRPs) in Australian aged care homes have been studied previously. However, little is known about the acceptance and implementation of pharmacists' recommendations by general practitioners (GPs) to resolve DRPs. Objectives The primary objective of this study was to investigate the number and nature of DRPs identified by accredited clinical pharmacists. The secondary objective was to study the GP acceptance and implementation of pharmacist recommendations to resolve DRPs. Methods This was a retrospective study of 500 randomly selected, de‐identified medication reviews performed by 10 accredited clinical pharmacists over 6 months across 62 aged care homes. The DRPs identified by pharmacists were subsequently classified by the drugs involved, types of problem (indication, effectiveness and safety) and medical diagnoses of the patient. GP written feedback on the medication review reports determined implementation of pharmacists' recommendations to resolve the DRPs. Results A total of 1433 DRPs were identified in 480 of the 500 residents. Potential DRPs were frequently classified as risk of adverse drug reactions, need for additional monitoring and inappropriate choice of a drug. Alimentary, cardiovascular, central nervous system and respiratory drugs were most frequently implicated, accounting for more than 75% of the DRPs. GPs' acceptance and implementation of pharmacists recommendations were 72.5% (95% CI; 70.2, 74.8) and 58.1% (95% CI; 55.5, 60.6), respectively. Conclusions Over 96% of the residents had potential DRPs identified by pharmacists. GP acceptance of pharmacists' recommendations was independent of the drug category, but not independent of the disease category.     

The contribution of patient interviews to the identification of drug‐related problems in home medication review

What is known and Objective: To determine to what extent patient interviews contribute to the identification of drug‐related problems (DRPs) in home medication reviews, in terms of number, type and clinical relevance. Methods: We performed a cross‐sectional study within the intervention arm of a randomized controlled trial. Patients were recruited from 10 Dutch community pharmacies. Patients were eligible if they were home‐dwelling, aged 65 years and over and used five or more different drugs, including at least one cardiovascular or antidiabetic drug. The community pharmacist interviewed the patient at home about the medicines and identified potential DRPs in combination with medication and clinical records. This medication review was assessed and modified by an independent pharmacist reviewers’ panel. Outcomes were the number and type of DRPs and recommendations and percentage of clinical relevant DRPs. Clinical relevance of DRPs was assessed by DRPs assigned a high priority, DRPs followed by recommendations for drug change and DRPs followed by implemented recommendations for drug change. Results: A total of 1565 potential DRPs and recommendations (10 per patient).were identified for 155 patients (median age, 76 years; 54% women). Fifty‐eight per cent of all recommendations involved a drug change; 27% of all DRPs were identified during patient interviews and 74% from medication and clinical records. Compared to DRPs identified from patient medication and clinical records, DRPs identified during patient interviews were more frequently assigned a high priority (OR = 1·8 [1·4–2·2]), were more frequently associated with recommendations for drug change (OR = 2·4 [1·9–3·1]) and were implemented recommendations for drug change (OR = 2·8 [2·1–3·7]). What is new and Conclusion: This study shows that more than a quarter of all DRPs were identified during patient interviews. DRPs identified during patient interviews were more frequently assigned a higher clinical relevance.     

Impact of a pediatric clinical pharmacist in the pediatric intensive care unit

OBJECTIVE: To study the impact of a clinical pharmacist in a pediatric intensive care unit. The goals of the study were to determine the type and quantity of patient care interventions recommended by a clinical pharmacist and to specifically examine cost savings (or loss) that resulted from clinical pharmacist recommendations. DESIGN: A prospective case series. SETTING: Ten-bed pediatric intensive care unit in a university-affiliated children's hospital. PATIENTS: All patients admitted to the pediatric intensive care unit during the study period. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: During the 24-wk study period, the pediatric clinical pharmacist documented all interventions that occurred during her shift. She rounded with the pediatric intensive care unit team approximately two times a week and reviewed medication lists daily. Drug acquisition costs were used to calculate drug cost savings. Demographic information was collected on all the patients in the pediatric intensive care unit during the study period. There were 35 recommendations per 100 patient days. The most common interventions were dosage changes (28%), drug information (26%), and miscellaneous information (22%). The average time spent per day by the clinical pharmacist in the pediatric intensive care unit was 0.73 hrs or 0.02 full-time equivalent. The total cost direct savings for the study period was $1,977. Extrapolated to direct cost savings per year, the total amount saved was $9,135/year or 0.15 full-time equivalent. Indirect savings from educational activities, avoidance of medication errors, and optimization of medical therapies represent an additional nonquantifiable amount. CONCLUSION: We conclude that a clinical pharmacist is an important and cost-effective member of the pediatric intensive care unit team.     

Pharmacist Involvement in Cancer Pain Management: A Systematic Review and Meta-Analysis

This review aimed to critically evaluate the impact of pharmacist involvement in managing pain in cancer patients. Databases (including MEDLINE, Embase and CENTRAL) were searched with a broad search strategy for studies involving pharmacists and cancer pain management until February 10, 2021. The quality of studies and evidence were assessed using standardized tools and GRADE, respectively. A random-effects model was used for meta-analysis. Sixty-four studies were included. Common interventions delivered by the pharmacists were medication review, patient education, adverse drug reactions (ADRs) detection and management, pharmacological recommendations (in dosing and pharmacotherapy choice), and pain assessment. A pooled analysis of 3 randomized control trials showed a significant reduction in pain intensity with a standardized mean difference (SMD) of 0.35 [95% confidence intervals (CI): -0.55, -0.16]. Pooled analyses from nonrandomized studies of interventions also showed significant results in reduction of ADRs with an odds ratio of 0.69 (95% CI: 0.61, 0.79) and improvement in quality of life with SMD of 0.80 (95% CI: 0.29, 1.32). Thus, pharmacists significantly improve the clinical outcomes of cancer patients related to pain. This indicates the involvement of pharmacists directly or in collaboration with healthcare professionals in the oncology team is highly beneficial for the patients.PerspectivesThis systematic review presents a comprehensive evaluation of pharmacist involvement in cancer pain management. This shows the importance of direct involvement of the pharmacist or as an important member of the multidisciplinary oncology team.     

Productivity costs and determinants of productivity in HIV-infected patients

BACKGROUND: In HIV-infected patients, reduced ability to work may be an important component of the societal costs of this disease. Few data about productivity costs in HIV-infected patients are available. OBJECTIVE: The goals of this study were to estimate productivity costs in the HIV-infected population in Switzerland and to identify characteristics that may influence patient productivity. METHODS: This cross-sectional study included all patients younger than retirement age (65 years for men and 62 years for women) who were enrolled in the Swiss HIV Cohort Study in 2002. Measures of productivity losses in this population were based on patients' ability to work and the median monthly wage rates adjusted for age, sex, and educational level in Switzerland. Factors associated with ability to work were analyzed in a multivariate ordinary logistic regression (proportional odds) model. As of July 1, 2002, the exchange rate for US dollars to Swiss francs (CHF) was US $1.00 approximately equal to CHF 1.48. RESULTS: A total of 5319 HIV-infected patients (3665 men [68.9%] and 1655 women [31.1%]; mean [SD] age, 40.6 [8.4] years; range, 17-64 years) were included in the study. The mean annual productivity loss per patient was estimated at CHF 22,910 (95% CI, CHF 22,064-CHF 23, 756). Ability to work was independently associated with the following (P < 0.001 for all): age (10-year increase: odds ratio [OR], 0.60 [95% CI, 0.54-0.62]), sex (female/male: OR, 0.73 [95% CI, 0.63-0.84]), history of IV drug use (OR, 0.22 [95% CI, 0.19-0.26]), time since first positive HIV test (>10 years vs < or = 10 years: OR, 0.66 [95% CI, 0.58-0.76]), CD4 cell count (201-500 vs 0-200 cells/microL: OR, 1.68 [95% CI, 1.38-2.46]; > or =501 vs 0-200 cells/microL: OR, 2.01 [95%, CI, 1.64-2.46]), history of AIDS-indicator disease (OR, 0.47 [95% CI, 0.41-0.55]), stable partnership during the last 6 months (OR, 1.63 [95% CI, 1.43-1.86]), and educational level (higher vs basic: OR, 1.68 [95% CI, 1.45-1.95]). CONCLUSIONS: Productivity losses to society for the HIV-infected population appeared to be substantial in this analysis. Given a patient's clinical health status, a higher education level and a stable partnership were associated with greater ability to work. Socioeconomic characteristics may influence the cost-effectiveness of health care interventions in HIV-infected patients.     

Overnight and Postcall Errors in Medication Orders

Objective: To compare the error rates in medication orders by physicians who were off call, on overnight call, and postcall. Methods: This was a retrospective review of inpatient medication orders, pharmacy records, and resident physician work schedules in a university‐affiliated community teaching hospital with residency programs in emergency medicine, family practice, internal medicine, obstetrics, pediatrics, and surgery. The authors calculated error rates, odds ratios (ORs), and 95% confidence intervals (95% CIs) for physicians during April 2000. Results: In 8,195 medication orders, there were 177 errors (2.16% overall error rate). There was an increased error rate for overnight and postcall orders (2.71%, OR 1.44, 95% CI = 1.06 to 1.95) in comparison to orders written by off‐call physicians (1.90%). Error rates were significantly higher on the medical/surgical wards during the overnight (3.91%, OR 1.89, 95% CI = 1.22 to 2.92) and postcall (3.41%, OR 1.64, 95% CI = 1.10 to 2.43) periods compared with the off‐call (2.11%) period, and postgraduate year 1 (PGY1) physicians had a higher overnight error rate (4.23%, OR 2.28, 95% CI = 1.44 to 3.61). Error rates were also higher on the medical/surgical wards compared with critical care units (2.62% vs. 1.22%, OR 2.17, 95% CI = 1.48 to 3.18). The PGY1 physicians had error rates similar to those of the PGY2–5 physicians when off call, but were significantly higher on overnight call (4.23% vs. 0.52%, OR 8.47, 95% CI = 2.00 to 35.82). Conclusions: Medication‐ordering error rates were higher for overnight and postcall physicians, particularly on the general medical/surgical wards, and in PGY1 physicians during the overnight period.     

Care and Decision-Making at the End of Life for Patients With a Non-Western Migration Background Living in The Netherlands: A Nationwide Mortality Follow-Back Study

ContextMigrant populations across Europe are aging and will increasingly need end-of-life care.ObjectiveThe objectives of this study were to gain insight into end-of-life care and decision-making for patients with a non-western migration background and assess differences compared to patients with a Dutch or western migration background.MethodsA mortality follow-back study was conducted using a stratified sample of death certificates of persons who died between August and December 2015, obtained from the central death registry of Statistics Netherlands. Questionnaires were sent to the attending physician (n = 9351; response 78%). Patients aged ≥18 years who died a nonsudden death were included in this study (n = 5327).ResultsPatients with a non-western migration background are more likely than patients with a Dutch or western migration background to be admitted to and die in hospital (51.6% vs. 33.9% [OR 1.74; 95% CI 1.26–2.41]; 39.1% vs. 20.1% [OR 1.96; 95% CI 1.39–2.78]); less likely to receive morphine or morphine-like medication and continuous deep sedation (72.8% vs. 80.1% [OR 0.62; 95% CI 0.43–0.89]; 16.8% vs. 25.2% [OR 0.52; 95% CI 0.34–0.80]); and more likely to receive end-of-life care that, according to physicians, is directed at curation for too long (6.8% vs. 1.7% [OR 3.61; 95% CI 1.83–7.12]). End-of-life decisions are made less frequently for patients with a non-western migration background (71.6% vs. 79.2% [OR 0.64; 95% CI 0.45–0.91]). Characteristics of decision-making are similar.ConclusionEnd-of-life care for patients with a non-western migration background focuses more, or longer on maximum, curative treatment and end-of-life decisions are made less often.     

Assessment for chronic kidney disease service in high-risk patients at community health clinics

BACKGROUND: Chronic kidney disease (CKD) poses significant public health concerns. Early identification and interventions can help prevent or slow progression to end-stage renal disease. OBJECTIVE: To characterize CKD in high-risk indigent patients in a primary care setting and evaluate opportunities for pharmacists to work collaboratively with physicians to improve medication use and CKD patient outcomes. METHODS: Medical records of 200 patients with diabetes mellitus and/or hypertension were reviewed by the clinical pharmacist. Estimated glomerular filtration rate (creatinine clearance [Cl(cr)]) and urinalysis were used to identify and stage CKD according to published guidelines. Glycosylated hemoglobin concentrations and blood pressures were recorded. The pharmacist evaluated medications for possible drug-related problems (DRPs), made therapeutic recommendations, and evaluated the acceptance rate by physicians. RESULTS: One hundred nineteen patients met inclusion criteria, and a total of 68.9% met CKD criteria: stage 1, 16.0%; stage 2, 20.2%; stage 3, 25.2%; stage 4, 1.7%; stage 5, 0.8%; and not stageable, 5.0%. A total of 381 DRPs were identified, averaging 3.2 (1.7) per patient (range 0-11). The number of DRPs correlated with Cl(cr) (r = -0.25; p = 0.007). Therapeutic recommendations included change of drug, dose and/or interval adjustment of the current drug, discontinuation of nonsteroidal antiinflammatory drugs, additional laboratory monitoring, meeting goal blood pressure and glycosylated hemoglobin, adding renoprotective drug and/or low-dose aspirin, and nephrologist referral. Fewer than half (40.9%) of the recommendations were accepted or accepted with modifications, and an approximately equal percentage were not accepted by the physicians. CONCLUSIONS: CKD prevalence was high among the patients evaluated here. New guidelines are available to assist in managing CKD ambulatory patients. Pharmacist collaboration with physicians may optimize CKD screening in high-risk patients and improve medication usage.     

Underuse of indicated medications among physically frail older US veterans at the time of hospital discharge: Results of a cross-sectional analysis of data from the Geriatric Evaluation and Management Drug Study

Background: Medication underutilization, or the omission of a potentially beneficial medication indicated for disease management, is common among older adults but poorly understood.Objectives: The aims of this work were to assess the prevalence of medication underuse and to determine whether polypharmacy or comorbidity was associated with medication underuse among physically frail older veterans transitioning from the hospital to the community.Methods: This was a cross-sectional analysis of patients who were discharged from 11 US veterans' hospitals to outpatient care, based on data from the Geriatric Evaluation and Management Drug Study, a substudy of the Veterans Affairs Cooperative Study of geriatric evaluation and management. Patients were enrolled between August 31, 1995, and January 31, 1999. To qualify for the study, patients had to be aged ≥65 years, hospitalized in a medical or surgical ward for >48 hours, and meet ≥2 of the following criteria: moderate functional disability; recent cerebrovascular accident with residual neurological deficit; history of ≥1 fall in the previous 3 months; documented difficulty with walking (ie, requiring personal assistance or equipment), not including preadmission use of a wheelchair with ability to transfer to and from chair independently; malnutrition (admission serum albumin of 3.5 g/dL, <80% of ideal body weight, or recent ≥15-lb weight loss reported in admission history); dementia; depression; documented diagnosis of new fracture or revision needed of older fracture; unplanned admission within 3 months of previous admission; and prolonged bed rest. Clinical pharmacist/physician pairs reviewed medical records and medication lists and independently applied the Assessment of Underutilization (AOU) index to determine omissions of indicated medications. Discordances in index ratings were resolved during clinical consensus conferences. The primary outcome measure was the percentage of patients with ≥1 medication omission detected by the AOU. Multivariable logistic regression analyses identified factors associated with underuse.Results: A total of 384 patients were included in the study. The majority (53.6%) were between the ages of 65 and 74 years, and the mean (SD) Charlson comorbidity index was 2.44 (1.93). Overall, 374 patients (97.4%) were men and 274 (71.4%) were white. Medication undertreatment occurred in 238 participants (62.0%). Diseases of the Accepted for publication October 26, 2009. circulatory, endocrine/nutritional, musculoskeletal, and respiratory systems were the most commonly undertreated conditions. The indicated medications most likely to be omitted were nitrates for those with a history of myocardial infarction, multivitamins in those with malnutrition, and inhaled anticholinergics for chronic obstructive airways disease. Statistically significant factors associated with medication underuse included limitations in activities of daily living (adjusted odds ratio [AOR], 2.17 [95% CI, 1.27–3.71]; P = 0.01), being white (AOR, 1.70 [95% CI, 1.06–2.71]; P = 0.03), and Charlson comorbidity index (AOR, 1.13 for each 1-point increase [95% CI, 1.00–1.27]; P = 0.04). Discharge from a general medicine service as opposed to a surgical service was associated with lower risk of medication underuse (AOR, 0.61 [95% CI, 0.38–0.98]; P = 0.04).Conclusions: Medication underuse was relatively common in this study. Patients with greater comorbidity, but not polypharmacy, had increased odds of undertreatment.     

Use of Out-of-hospital Interventions for the Pediatric Patient in an Urban Emergency Medical Services System

OBJECTIVE: To determine appropriateness of out-of-hospital interventions by emergency medical services (EMS) personnel on children with respiratory illnesses. METHODS: A retrospective, cross-sectional study was performed on a random sample of 304 children transported by an urban EMS system during 1994. Data were abstracted from EMScan (a computerized database of all EMS dispatches) and the EMS narrative records. Appropriate utilization of interventions was determined by comparison with the standard EMS protocol for respiratory complaints in this system. An assessment of whether interventions were inappropriately underutilized or inappropriately overutilized was made. Effect of severity of illness, patient age, transport times, and use of medical command on the use of interventions was evaluated. RESULTS: Two hundred three patients (67%) were classified as having respiratory distress. Overall, 56% of the patients received appropriate interventions, 39% received one or two inappropriate interventions, and 5% received three or more inappropriate interventions. Rates of inappropriate utilization with 95% CI for each intervention were: oxygen 16% (95% CI = 12 to 20), assisted ventilation 2% (95% CI = 0.5 to 4), medication use 9% (95% CI = 6 to 13), vascular access 11% (95% CI = 7 to 14), phlebotomy 9% (95% CI = 6 to 13), and cardiac monitoring 18% (95% CI = 14 to 22). Oxygen and medications were underutilized (p < 0.005), whereas vascular access, cardiac monitoring, and phlebotomy were overutilized (p < 0.005). Online medical command (used in 9% of transports) improved appropriate use of vascular access [OR 8.3 (95% CI = 3 to 25) (p < 0.001)] and cardiac monitoring [OR = 3 (95% CI = 1 to 8) (p < 0.05)]. CONCLUSIONS: Emergency medical services personnel underutilized oxygen and medications and overutilized vascular access, phlebotomy, and cardiac monitoring in children with respiratory illness in this urban setting. Increasing patient age, transport times, and illness severity tend to increase the use of certain interventions, while contact with online medical direction seems to improve appropriate use of interventions.     

False-negative and False-positive Errors in Abdominal Pain Evaluation Failure to Diagnose Acute Appendicitis and Unnecessary Surgery

OBJECTIVES: To test the hypothesis that physician errors (failure to diagnose appendicitis at initial evaluation) correlate with adverse outcome. The authors also postulated that physician errors would correlate with delays in surgery, delays in surgery would correlate with adverse outcomes, and physician errors would occur on patients with atypical presentations. METHODS: This was a retrospective two-arm observational cohort study at 12 acute care hospitals: 1) consecutive patients who had an appendectomy for appendicitis and 2) consecutive emergency department abdominal pain patients. Outcome measures were adverse events (perforation, abscess) and physician diagnostic performance (false-positive decisions, false-negative decisions). RESULTS: The appendectomy arm of the study included 1, 026 patients with 110 (10.5%) false-positive decisions (range by hospital 4.7% to 19.5%). Of the 916 patients with appendicitis, 170 (18.6%) false-negative decisions were made (range by hospital 10.6% to 27.8%). Patients who had false-negative decisions had increased risks of perforation (r = 0.59, p = 0.058) and of abscess formation (r = 0.81, p = 0.002). For admitted patients, when the inhospital delay before surgery was >20 hours, the risk of perforation was increased [2.9 odds ratio (OR) 95% CI = 1.8 to 4.8]. The amount of delay from initial physician evaluation until surgery varied with physician diagnostic performance: 7.0 hours (95% CI = 6.7 to 7.4) if the initial physician made the diagnosis, 72.4 hours (95% CI = 51.2 to 93.7) if the initial office physician missed the diagnosis, and 63.1 hours (95% CI = 47.9 to 78.4) if the initial emergency physician missed the diagnosis. Patients whose diagnosis was initially missed by the physician had fewer signs and symptoms of appendicitis than patients whose diagnosis was made initially [appendicitis score 2.0 (95% CI = 1.6 to 2.3) vs 6.5 (95% CI = 6.4 to 6.7)]. Older patients (>41 years old) had more false-negative decisions and a higher risk of perforation or abscess (3.5 OR 95% CI = 2.4 to 5.1). False-positive decisions were made for patients who had signs and symptoms similar to those of appendicitis patients [appendicitis score 5.7 (95% CI = 5.2 to 6.1) vs 6.5 (95% CI = 6.4 to 6.7)]. Female patients had an increased risk of false-positive surgery (2.3 OR 95% CI = 1.5 to 3.4). The abdominal pain arm of the study included 1,118 consecutive patients submitted by eight hospitals, with 44 patients having appendicitis. Hospitals with observation units compared with hospitals without observation units had a higher "rule out appendicitis" evaluation rate [33.7% (95% CI = 27 to 38) vs 24.7% (95% CI = 23 to 27)] and a similar hospital admission rate (27.6% vs 24.7%, p = NS). There was a lower miss-diagnosis rate (15.1% vs 19.4%, p = NS power 0.02), lower perforation rate (19.0% vs 20.6%, p = NS power 0.05), and lower abscess rate (5.6% vs 6.9%, p = NS power 0.06), but these did not reach statistical significance. CONCLUSIONS: Errors in physician diagnostic decisions correlated with patient clinical findings, i.e., the missed diagnoses were on appendicitis patients with few clinical findings and unnecessary surgeries were on non-appendicitis patients with clinical findings similar to those of patients with appendicitis. Adverse events (perforation, abscess formation) correlated with physician false-negative decisions.
