Can automated alerts within computerized physician order entry improve compliance with laboratory practice guidelines for ordering Pap tests?

Use of Epic Electronic Health Record System for Health Care Research: Scoping Review

BACKGROUND

Electronic health records (EHRs) enable health data exchange across interconnected systems from varied settings. Epic is among the 5 leading EHR providers and is the most adopted EHR system across the globe. Despite its global reach, there is a gap in the literature detailing how EHR systems such as Epic have been used for health care research.

OBJECTIVE

The objective of this scoping review is to synthesize the available literature on use cases of the Epic EHR for research in various areas of clinical and health sciences.

METHODS

We used established scoping review methods and searched 9 major information repositories, including databases and gray literature sources. To categorize the research data, we developed detailed criteria for 5 major research domains to present the results.

RESULTS

We present a comprehensive picture of the method types in 5 research domains. A total of 4669 articles were screened by 2 independent reviewers at each stage, while 206 articles were abstracted. Most studies were from the United States, with a sharp increase in volume from the year 2015 onwards. Most articles focused on clinical care, health services research and clinical decision support. Among research designs, most studies used longitudinal designs, followed by interventional studies implemented at single sites in adult populations. Important facilitators and barriers to the use of Epic and EHRs in general were identified. Important lessons to the use of Epic and other EHRs for research purposes were also synthesized.

CONCLUSIONS

The Epic EHR provides a wide variety of functions that are helpful toward research in several domains, including clinical and population health, quality improvement, and the development of clinical decision support tools. As Epic is reported to be the most globally adopted EHR, researchers can take advantage of its various system features, including pooled data, integration of modules and developing decision support tools. Such research opportunities afforded by the system can contribute to improving quality of care, building health system efficiencies, and conducting population-level studies. Although this review is limited to the Epic EHR system, the larger lessons are generalizable to other EHRs.

Using the Electronic Medical Record to Increase Laboratory Test Monitoring in Ocular Inflammation Patients: A Quality Improvement Study

BACKGROUND AND OBJECTIVES

Treatment of chronic, noninfectious ocular inflammation includes corticosteroids, disease-modifying antirheumatic medications, and biologics. To mitigate adverse effects associated with the use of these medications, routine laboratory test monitoring is recommended throughout treatment. We evaluated the effectiveness of an alert added to the electronic medical record (EMR) to aid in laboratory test monitoring for patients prescribed these high-risk medications.

METHODS

A prospective, interventional study assessed the effect of the alert within the EMR on laboratory test ordering at the Division of Ocular Immunology at the Wilmer Eye Institute. The primary outcome measure was the change in number of ordered laboratory tests at 3, 6, and 12 months after the alert activation compared with pre-intervention levels and overall through the study period. The laboratory tests that were monitored included complete blood count, comprehensive metabolic panel, dual-energy x-ray absorptiometry (DXA) scanning, fasting lipid panel, and interferon gamma release assays.

RESULTS

The laboratory test orders for 153 patients on high risk medications were analyzed. Only the frequency of ordering the DXA and interferon gamma release assays increased significantly, compared with baseline, throughout the study. Conversely, there was a significant decrease in the frequency of ordering of fasting lipid profiles and hemoglobin A 1c at each time point and for complete blood count and comprehensive metabolic panel at the 6-month time point.

CONCLUSION

An EMR alert results in increased laboratory test ordering initially for tests drawn on a yearly basis, but the effect on more frequently ordered tests wanes with time if the alert can be silenced by the provider. Nonetheless, it provides a novel mechanism to increase laboratory ordering in patients on high-risk medications that can be adapted for use in other EMR software. Future studies are needed to assess whether physician laboratory test ordering behavior is altered throughout the study period with the use of a non-silencable alert.

Canned Comments in the Hospital Laboratory Information System Can Decrease Microbiology Requests

OBJECTIVES

Phone calls to the microbiology laboratory can be to clarify culture results and provide education, but those calls also interrupt laboratory workflow. We characterized calls that the laboratory received and developed targeted comments to educate providers.

METHODS

Calls were logged and characterized, and we developed comments to address common call subjects. We applied the new comments to cultures and logged calls over the same interval the subsequent year. Data before and after implementation were analyzed.

RESULTS

Call volume decreased from 496 calls to 419 calls after implementation. There was a significant difference in level of training among callers (P < .005), but the nature of the calls did not change. Laboratory response showed an increase in release of previously generated data (eg, suppressed susceptibility results). Comments specifically developed to address intrinsic antibiotic resistance and common susceptibility patterns did not decrease call volume.

CONCLUSIONS

Implementation of comments in the laboratory information system decreased call volume, but targeted comments were less effective than anticipated.

Understanding User Acceptance of Clinical Decision Support Systems to Promote Increased Cancer Screening Rates in a Primary Care Practice

OBJECTIVE

Clinical decision support systems (CDDSs) in the electronic medical record (EMR) have been implemented in primary care settings to identify patients due for cancer screening tests, while functioning as a real time reminder system. There is little known about primary care providers (PCPs) perspective or user acceptance of CDSS. The purpose of this study was to investigate primary care provider perceptions of utilizing CDSS alerts in the EMR to promote increased screening rates for breast cancer, cervical cancer, and colorectal cancer.

METHODS

An electronic survey was administered to PCPs in a Midwest Health Institution community internal medicine practice from September 25, 2019 through November 27, 2019.

RESULTS

Among 37 participants (9 NP/Pas and 28 MD/DOs), the NP/PA group was more likely to agree that alerts were helpful (50%; P-value = .0335) and the number of alerts (89%; P = .0227) in the EMR was appropriate. The NP/PA group also was more likely to find alerts straightforward to use (78%, P = .0239). Both groups agreed about feeling comfortable using the health maintenance alerts (MD/DO = 79%; NP/PA = 100%).

CONCLUSION

CDSSs can promote and facilitate ordering of cancer screening tests. The use of technology can promptly identify patients due for a test and act as a reminder to the PCP. PCPs identify these alerts to be a beneficial tool in the EMR when they do not interrupt workflow and provide value to patient care. More work is needed to identify factors that could optimize alerts to be even more helpful, particularly to MD/DO groups.

Validation and Implementation of an Ordering Alert to Improve the Efficiency of Monoclonal Gammopathy Evaluation

OBJECTIVES

To evaluate the use of a provider ordering alert to improve laboratory efficiency and reduce costs.

METHODS

We conducted a retrospective study to assess the use of an institutional reflex panel for monoclonal gammopathy evaluation. We then created a clinical decision support (CDS) alert to educate and encourage providers to change their less-efficient orders to the reflex panel.

RESULTS

Our retrospective analysis demonstrated that an institutional reflex panel could be safely substituted for a less-efficient and higher-cost panel. The implemented CDS alert resulted in 79% of providers changing their high-cost order panel to an order panel based on the reflex algorithm.

CONCLUSIONS

The validated decision support alert demonstrated high levels of provider acceptance and directly led to operational and cost savings within the laboratory. Furthermore, these studies highlight the value of laboratory involvement with CDS efforts to provide agile and targeted provider ordering assistance.

Effect of an Electronic Health Record Decision Support Alert to Decrease Excess Cervical Cancer Screening

OBJECTIVE

Cervical cancer screening is often conducted in excess of current screening guidelines. The objective of this study was to evaluate the effect of an electronic health record (EHR) clinical decision support alert to decrease guideline-nonadherent cervical cancer screening beyond the age limits of screening or posthysterectomy.

MATERIALS AND METHODS

The proportion of guideline-nonadherent Pap tests in women younger than 21 years or older than 65 years or posthysterectomy were compared 4 months before and 3 months after implementation of an EHR clinical decision support alert warning providers that a Pap test is not indicated. Providers could cancel the Pap test or override the alert and place the order. Provider characteristics and Pap test indications were summarized by preintervention/postintervention period using descriptive statistics. The proportions of nonindicated Pap tests were compared by intervention period and provider characteristics using generalized estimating equation models.

RESULTS

In women beyond the screening age limits or posthysterectomy, a total of 388 Pap tests were ordered before intervention, and 313 tests were ordered after intervention. Proportion of guideline-nonadherent tests was similar before (62%) and after intervention (63%); thus, implementation of the clinical decision support alert did not change the proportion of guideline-nonadherent Pap tests ordered (OR = 1.08, 95% CI = 0.77-1.52). It is notable that 52% of guideline-nonadherent tests were ordered by 11 providers. Even when controlling for providers who ordered more than 1 test during the study period, multivariate analysis showed that male providers were more likely to order guideline-nonadherent Pap tests (OR = 2.30, 95% CI = 1.36-3.89); no other differences by provider characteristics were observed.

CONCLUSIONS

An EHR clinical decision support alert does not decrease guideline-nonadherent cervical cancer screening. These data suggest efforts to optimize clinical decision support should be focused on other aspects of cervical cancer prevention.

Decision Support Tools within the Electronic Health Record

Laboratory tests are an integral part of the electronic health record (EHR). Providing clinical decision support (CDS) for the ordering, collection, reporting, viewing, and interpretation of laboratory testing is a fundamental function of the EHR. The implementation of a sustainable, effective laboratory CDS program requires a commitment to standardization and harmonization of the laboratory dictionaries that are the foundation of laboratory-based CDS. In this review, the authors provide an overview of the tools available within the EHR to improve decision making throughout the entire laboratory testing process, from test order to clinical action.

Decreasing Inappropriate Use of Rasburicase to Promote Cost-Effective Care

BACKGROUND

Rasburicase is a recommended treatment of tumor lysis syndrome and patients at high-risk for developing tumor lysis syndrome. Unfortunately, it is expensive, and unnecessary use raises costs of care.

METHODS

Plan, Do, Study, Act methodology was used to decrease the inappropriate use of rasburicase. In the Plan phase, a multidisciplinary quality improvement team reviewed the rasburicase ordering process and its prescription patterns at Parkland Health and Hospital System between October 2015 and September 2017 to determine appropriate interventions for improvement. In the Do phase, interventions were deployed to improve rasburicase prescriptions. In the Study phase, the team reviewed the rasburicase orders and appropriateness from February 2018 to October 2018. During the Act phase, the interventions were found to be successful, and the process changes were solidified.

RESULTS

At baseline, 65 doses of rasburicase were administered during the 2-year baseline period, 21 of these (32.3%) were inappropriate. Review of the ordering process identified pitfalls: one-click ready-to-sign order, fixed default dose, no hard-stop alert requiring physicians to review and confirm appropriate indications, and lack of secondary pharmacy review. We aimed to reduce the percentage of inappropriate rasburicase orders from a baseline of 32.3% to 10% over 3 months. In February 2018, we implemented the interventions, which resulted in reduction in inappropriate rasburicase use, with only a single inappropriate order placed in 7 months postintervention.

CONCLUSION

A multidisciplinary approach and classic quality improvement methodology enabled us to reduce inappropriate rasburicase use. Straightforward electronic medical record interventions and secondary pharmacy review are effective in addressing overuse.

Effectiveness of Practices to Support Appropriate Laboratory Test Utilization: A Laboratory Medicine Best Practices Systematic Review and Meta-Analysis

Objectives

To evaluate the effectiveness of practices used to support appropriate clinical laboratory test utilization.

Methods

This review followed the Centers for Disease Control and Prevention (CDC) Laboratory Medicine Best Practices A6 cycle method. Eligible studies assessed one of the following practices for effect on outcomes relating to over- or underutilization: computerized provider order entry (CPOE), clinical decision support systems/tools (CDSS/CDST), education, feedback, test review, reflex testing, laboratory test utilization (LTU) teams, and any combination of these practices. Eligible outcomes included intermediate, systems outcomes (eg, number of tests ordered/performed and cost of tests), as well as patient-related outcomes (eg, length of hospital stay, readmission rates, morbidity, and mortality).

Results

Eighty-three studies met inclusion criteria. Fifty-one of these studies could be meta-analyzed. Strength of evidence ratings for each practice ranged from high to insufficient.

Conclusion

Practice recommendations are made for CPOE (specifically, modifications to existing CPOE), reflex testing, and combined practices. No recommendation for or against could be made for CDSS/CDST, education, feedback, test review, and LTU. Findings from this review serve to inform guidance for future studies.

Impact of Patient Reminders on Papanicolaou Test Completion for High-Risk Patients Identified by a Clinical Decision Support System

Background: A clinical decision support system (CDSS) for cervical cancer screening identifies patients due for routine cervical cancer screening. Yet, high-risk patients who require more frequent screening or earlier follow-up to address past abnormal results are not identified. We aimed to assess the effect of a complex CDSS, incorporating national guidelines for high-risk patient screening and abnormal result management, its implementation to identify patients overdue for testing, and the outcome of sending a targeted recommendation for follow-up.

Materials and Methods: At three primary care clinics affiliated with an academic medical center, a reminder recommending an appointment for Papanicolaou (Pap) testing or Pap and human papillomavirus cotesting was sent to high-risk women aged 18 through 65 years (intervention group) identified by CDSS as overdue for testing. Historical control patients, who did not receive a reminder, were identified by CDSS 1 year before the date when reminders were sent to the intervention group. Test completion rates were compared between the intervention and control groups through a generalized estimating equation extension.

Results: Across the three sites, the average completion rate of recommended follow-up testing was significantly higher in the intervention group at 23.7% (61/257) than the completion rate at 3.3% (17/516) in the control group (p < 0.001).

Conclusions: A CDSS with enhanced capabilities to identify high-risk women due for cervical cancer testing beyond routine screening intervals, with subsequent patient notification, has the potential to decrease cervical precancer and cancer by improving adherence to guideline-compliant follow-up and needed treatment.

The role of informatics in patient-centered care and personalized medicine

The practice of cytopathology has dramatically changed due to advances in genomics and information technology. Cytology laboratories have accordingly become increasingly dependent on pathology informatics support to meet the emerging demands of precision medicine. Pathology informatics deals with information technology in the laboratory, and the impact of this technology on workflow processes and staff who interact with these tools. This article covers the critical role that laboratory information systems, electronic medical records, and digital imaging plays in patient-centered personalized medicine. The value of integrated diagnostic reports, clinical decision support, and the use of whole-slide imaging to better evaluate cytology samples destined for molecular testing is discussed. Image analysis that offers more precise and quantitative measurements in cytology is addressed, as well as the role of bioinformatics tools to cope with Big Data from next-generation sequencing. This article also highlights the barriers to the widespread adoption of these disruptive technologies due to regulatory obstacles, limited commercial solutions, poor interoperability, and lack of standardization.

Personalization and Patient Involvement in Decision Support Systems: Current Trends

OBJECTIVES

This survey aims at highlighting the latest trends (2012-2014) on the development, use, and evaluation of Information and Communication Technologies (ICT) based decision support systems (DSSs) in medicine, with a particular focus on patient-centered and personalized care.

METHODS

We considered papers published on scientific journals, by querying PubMed and Web of ScienceTM. Included studies focused on the implementation or evaluation of ICT-based tools used in clinical practice. A separate search was performed on computerized physician order entry systems (CPOEs), since they are increasingly embedding patient-tailored decision support.

RESULTS

We found 73 papers on DSSs (53 on specific ICT tools) and 72 papers on CPOEs. Although decision support through the delivery of recommendations is frequent (28/53 papers), our review highlighted also DSSs only based on efficient information presentation (25/53). Patient participation in making decisions is still limited (9/53), and mostly focused on risk communication. The most represented medical area is cancer (12%). Policy makers are beginning to be included among stakeholders (6/73), but integration with hospital information systems is still low. Concerning knowledge representation/management issues, we identified a trend towards building inference engines on top of standard data models. Most of the tools (57%) underwent a formal assessment study, even if half of them aimed at evaluating usability and not effectiveness.

CONCLUSIONS

Overall, we have noticed interesting evolutions of medical DSSs to improve communication with the patient, consider the economic and organizational impact, and use standard models for knowledge representation. However, systems focusing on patient-centered care still do not seem to be available at large.

Roles of Health Care Providers and Patients in Initiation of Unnecessary Papanicolaou Testing After Total Hysterectomy

OBJECTIVES

To assess Papanicolaou (Pap) testing use among US adult women with a history of a total hysterectomy for a benign condition and the roles of health care providers and patients in the initiation of screening Pap tests.

METHODS

We used 2000 to 2013 data from the National Health Interview Survey on women aged 20 years or older who had undergone a hysterectomy (n = 11 616) to estimate unnecessary Pap test use.

RESULTS

The percentage of self-reported Pap testing in the preceding 3 years among women who had undergone a hysterectomy decreased from 72.2% in 2000 to 53.3% in 2013. In 2013, 42.4% of women who had undergone a hysterectomy reported receiving recommendations for screening from a health care provider in the past year (32% of which were unnecessary), and 32.1% reported undergoing Pap tests in the preceding year (22.1% of which were unnecessary). Although the majority of Pap tests were performed at a clinician's recommendation, approximately one fourth were initiated by patients without clinician recommendations.

CONCLUSIONS

Health care providers should advise women who have had a total hysterectomy for a benign condition on appropriate use of screening services.

Unintended adverse consequences of electronic health record introduction to a mature universal HIV screening program

Early HIV detection and treatment decreases morbidity and mortality and reduces high-risk behaviors. Many Emergency Departments (EDs) have HIV screening programs as recommended by the Centers for Disease Control and Prevention. Recent federal legislation includes incentives for electronic health record (EHR) adoption. Our objective was to analyze the impact of conversion to EHR on a mature ED-based HIV screening program. A retrospective pre- and post-EHR implementation cohort study was conducted in a large urban, academic ED. Medical records were reviewed for HIV screening rates from August 2008 through October 2013. On 1 November 2010, a comprehensive EHR system was implemented throughout the hospital. Before EHR implementation, labs were requested by providers by paper orders with HIV-1/2 automatically pre-selected on every form. This universal ordering protocol was not duplicated in the new EHR; rather it required a provider to manually enter the order. Using a chi-squared test, we compared HIV testing in the 6 months before and after EHR implementation; 55,054 patients presented before, and 50,576 after EHR implementation. Age, sex, race, acuity of presenting condition, and HIV seropositivity rates were similar pre- and post-EHR, and there were no major patient or provider changes during this period. Average HIV testing rate was 37.7% of all ED patients pre-, and 22.3% post-EHR, a 41% decline (p < 0.0001), leading to 167 missed new diagnoses after EHR. The rate of HIV screening in the ED decreased after EHR implementation, and could have been improved with more thoughtful inclusion of existing human processes in its design.

Improving Adherence to Practice Guidelines for Anticoagulation in Patients Receiving Neuraxial Anesthesia Using an Electronic Order Entry Alert System

OBJECTIVES

Epidural analgesia is frequently used to alleviate postoperative pain. Though rare, epidural hematoma continues to be a feared complication of neuraxial analgesia. The risk of epidural hematoma is likely increased when certain regimens are used for prophylaxis/treatment of venous thromboembolism. To help decrease the risk, we developed an alert in our electronic medical record to assist providers with adherence to published guidelines addressing neuraxial analgesia and anticoagulation.

METHODS

Patient data were collected retrospectively 3 months before and 3 months after the initiation of the computerized alert to assess the effectiveness of the alert. Patients were included if they had a procedure code associated with epidural analgesia. Pregnant patients and children were excluded. Type and frequency of antithrombotic medications were recorded for comparison to published practice guidelines.

RESULTS

Using Poisson regression to describe the data, patients with epidurals after the best practice alert observed a 61% decrease in the expected number of days of exposure to inappropriate doses of anticoagulation versus patients treated before implementation of the alert.

CONCLUSION

Unapproved antithrombotic administration was significantly reduced after initiation of the alert system. This simple electronic alert was found to have a protective effect for patients receiving both anticoagulation and epidural analgesia.

Effectiveness of a computerized alert system based on re-testing intervals for limiting the inappropriateness of laboratory test requests

OBJECTIVES

There is consolidated evidence that the burden of inappropriate laboratory test requests is very high, up to 70%. We describe here the function of a computerized alert system linked to the order entry, designed to limit the number of potentially inappropriate laboratory test requests.

DESIGN AND METHODS

A computerized alert system based on re-testing intervals and entailing the generation of pop-up alerts when preset criteria of appropriateness for 15 laboratory tests were violated was implemented in two clinical wards of the University Hospital of Parma. The effectiveness of the system for limiting potentially inappropriate tests was monitored for 6months.

RESULTS

Overall, 765/3539 (22%) test requests violated the preset criteria of appropriateness and generated the appearance of electronic alert. After alert appearance, 591 requests were annulled (17% of total tests requested and 77% of tests alerted, respectively). The total number of test requests violating the preset criteria of inappropriateness constantly decreased over time (26% in the first three months of implementation versus 17% in the following period; p<0.001). The total financial saving of test withdrawn was 3387 Euros (12.8% of the total test cost) throughout the study period.

CONCLUSIONS

The results of this study suggest that a computerized alert system may be effective to limit the inappropriateness of laboratory test requests, generating significant economic saving and educating physicians to a more efficient use of laboratory resources.
