Electronic Fetal Monitoring and Health Information Technology



Electronic Fetal Monitoring and Health Information Technology





Despite controversy, the use of electronic fetal monitoring (EFM) technology in birth is ubiquitous, and obstetric care providers must understand the nature and capabilities of the tools in use. As a technology, EFM is not only a biophysical and electronic engineering tool to capture the fetal heart rate (FHR) signal, but in many cases also the point-of-care (POC) tool linked to a powerful clinical information system. A solid understanding of the information technology capabilities of EFM is necessary for providers to harness the information benefits and use EFM appropriately and effectively for optimum birth outcomes. This chapter provides a brief introduction on how EFM relates to the electronic health record (HER), computerized clinical information systems, and informatics. Clinicians are encouraged to access the chapter references for additional learning.


THE ELECTRONIC HEALTH RECORD AND HEALTH INFORMATION TECHNOLOGY

The Institute of Medicine (IOM) report Crossing the Quality Chasm first called for elimination of handwritten data and set a goal to implement a paperless EHR before the end of the decade, citing evidence that the EHR improves health care quality, safety and efficiency.1 The electronic format provides a record of clinical data that is legible, organized, complete, and accessible by multiple users across sites of care and episodes of care. In addition, the digital record creates a database of clinical information that can be automatically analyzed. This IOM report energized the development of health information technology (HIT) and the application of information processing technology (computer hardware and software) to enable the collection, analysis, storage, retrieval, and sharing of health care data, information, and knowledge for communication and decision-making. In 2009, The American Recovery and Reinvestment Act (ARRA) and the Health Information Technology for Economic and Clinical Health Act (HITECH Act) created funding and reimbursement incentives for the adoption of EHRs that included expectations for using certified systems (the right technology) for standard use (the right use of technology), commonly referred to as “meaningful use.”2,3 The Office of the National Coordinator for HIT (ONC) is the complete source for a current list of certified technology products and specific meaningful use criteria (Office of the National Coordinator for Health Information Technology [ONC]).4 The ARRA goals include improving care coordination through the effective use of HIT and effective health information exchange (HIE), goals that are relevant to obstetric patients and fetal monitoring. Effective use aims to bring key data directly to the frontline providers at the point-of-care, reduce duplicative work, and provide access to clinical data immediately (such as data entry of the mother’s expected delivery date that is entered once and flows to all parts of the medical record simultaneously, or immediate access to interpret and document on a fetal tracing). Effective HIE aims to improve interoperable data standards, so information is portable, travels with the patient, and can be shared among providers (such as access to prenatal FHR assessments and diagnostics). Collectively, these strategies will deliver the right information to the right person at the right time.

The transition to an EHR poses education and practice challenges for clinicians. A multidisciplinary summit sponsored by the American Health Information Management Association addressed such training needs and listed specific actions for not only health care workers, but for employers, vendors, educators, and the government to promote workforce competencies.5 This panel recommended that health care workers themselves self-assess knowledge gaps and seek ongoing professional development. Obstetric clinicians must recognize how the national agenda
is shaping EFM practice with clinical information systems and informatics.



ELECTRONIC FETAL MONITORING AND CLINICAL INFORMATION SYSTEMS

Clinical information systems (CIS) are networks of computers that share clinical data in a digital format; these are typically bedside computer workstations connected to a central server. The CIS is the backbone or architecture for the paperless EHR. The use of CIS in obstetrics expanded in the 1990s with “perinatal systems” capable of transmitting and displaying the fetal tracings recorded from all bedside stations in the system on all screens in the system (surveillance) and storing the tracings in an electronic format on an optical disk (archiving). Networks expanded to include remote transmission of the fetal tracing through an Internet connection or wireless device to and from settings outside the labor and delivery unit, such as antepartum testing units and ambulatory offices, on a desktop or hand-held device. Clinicians began documenting on the computer tracing. Gradually, the monitor paper was used less or turned off. This conversion from the traditional fetal monitor paper to a digital perinatal system challenges and changes clinical workflow and requires substantial staff effort. Clinicians need to see direct benefits from the system. Initially, clinicians were most interested in the risk management benefit of what came to be known as “central monitoring” or the display of all fetal tracings at a centrally located station. With central monitoring, clinicians could monitor tracings when a care provider could not be at the bedside. Quality assurance projects reported less loss of tracings with electronic storage. And soon, clinicians recognized the value of the CIS database functions, including documentation or data entry, data analysis (such as aggregation and trending), and data reporting.

Perinatal systems are niche systems, developed to meet the unique clinical needs of a specialty area and are often separate from an organization’s enterprise-wide system because the fetal monitor that captures physiologic data is classified differently for device approval.3 Increasingly, perinatal documentation is being integrated into the enterprisewide CIS.


Perinatal Information System Functions

State-of-the-art perinatal systems provide a comprehensive and longitudinal EHR, with surveillance, archiving, documentation, and database applications in use across the care continuum, from prenatal primary care, to inpatient birth, newborn and postpartum, and back to postpartum primary care. This overview focuses on the applications, benefits, and limitations to consider in using computerized systems with EFM tracings (Table 6-1).


Surveillance

Effective surveillance, communication, and response to potential risk promote patient safety. The safety goal with EFM is to correctly identify, interpret, communicate, and intervene in response to the FHR tracing. Computerized EFM surveillance systems are intended to promote this safety goal and reduce risk. Computer surveillance can certainly help clinician surveillance, but there are some limitations to consider.

Central displays assist with the surveillance and communication aspects of safety. Although central displays can provide extra “eyes” for clinicians, a commonly voiced concern is the potential for the caregivers to focus their attention on the computer screen and assess the mother and fetus “from the desk” rather than at the bedside. Most perinatal systems have visual or auditory alarm functions to assist with surveillance by notifying the clinician when the FHR is outside preset parameters (such as signal loss or a change in baseline rates). However, when central displays and alarms are used, clinicians must acknowledge and respond for the safety process to be complete.

Clinician interpretation of an FHR tracing is a learned skill built from practicing visual analysis of pattern shapes. So, any distortion in the visual image (the scale or aspect ratio of the grid underlying the fetal waveform or the speed of the grid underlying the fetal waveform) could distort the appearance of the pattern shape and affect interpretation. A chief concern with the use of the digital tracing is the visual match between the traditional monitor paper printout and (1) the computer screen display (for interpreting the tracing during care), (2) the computer paper printout (for interpreting
the tracing generated from a computer printer), and (3) the archived tracing (for interpreting the tracing retrieved later from the archive) (Figure 6-1). In some cases, the computer screen, print-out, or stored pattern was not comparable to the actual monitor paper pattern and suggested different interpretations of the FHR status. The standards of speed and scale must be identical. Presently, there is no agreedon standard. Additional issues to consider with electronic displays are the clarity of the waveform and grids, the length of the tracing segment visible on the screen at one time, and the ergonomics of viewing the screen (brightness, colors, height, angle, position of the screen, split screens competing for visual attention).

The time stamp on the electronic EFM tracing is the legal medical record and must accurately correspond to the time of interventions. Because computer clocks and wall clocks are seldom synchronized, clinicians must have a clear policy regarding the time source, documentation of time, and documentation of discrepancies.


Archiving

Fetal monitoring tracings are a part of the medical record described as “patient identifiable source data” or data from which interpretations are derived, and these must be stored and retrievable. Many settings that use computer displays and archiving no longer run monitor paper during care or save monitor paper. However, when patient care is documented on the monitor paper tracing, the paper becomes a record of care and must be stored and retrievable. Some settings store both laser and paper records because of concern about retrieving archived tracings. Each organization should have policies and procedures for
managing all forms of fetal heart tracing media and records.6

The privacy and security of EHRs is now protected by the Health Insurance Portability and Accountability Act (HIPAA) standards (which pertain only to patient data in electronic form; the paper forms do not have this security protection).3 The security requirements protect electronic records from wrongful access, alteration, and loss through safeguards such as electronic user identification, audit trails of who has accessed a file, and a data back-up plan for network failure. To attain HIPAA compliance, the system must demonstrate that EFM tracings are retrievable and reproducible.



Documentation and Databases

CIS documentation or data entry is done using a variety of user input devices (keyboard, mouse, light pen, touch screen) at a bedside or mobile computer workstation or through wireless devices. Data are also automatically entered from biophysical monitoring devices (EFM, maternal blood pressure, pulse oximeter). With a fully electronic digital record, FHR data and any electronic documentation entered on the tracing will automatically flow to all parts of the EHR, so there is no need for duplicate charting or “double-documenting.” Eliminating duplicate documentation reduces the risk of transcription inconsistencies. The computer screens used for documentation (forms) are usually customizable and should be designed to match obstetrical workflow and standard of care. Electronic obstetrical records can improve the accuracy and completeness of data entry and improve the collection of outcome data.

Efficient data analysis and reporting are a necessity in today’s data-driven health care system. Collecting and documenting patient data in an EHR database is more efficient for analysis and reporting than the traditional paper-based medical record and unit log book. Documentation refers to the actual entry of data in the patient’s record, database refers to the collected data, and database management refers to the software program that performs the analysis of the collected data. All three components are necessary to generate information from collected data. The database software in a CIS facilitates more efficient clinical data collection, analysis, and reporting. The perinatal database software can store, aggregate, and analyze the individual patient data, such as FHR, labor events, and birth outcomes. However, clinical experts must be involved with the design of the database so that relevant perinatal data elements are defined and collected and meaningful analysis is accomplished. Data definitions must be clear, quantifiable, and agreed-on. Standardized terminology should be used so that data entries are consistent and can be compared over encounters and settings (such as standardized terminology for FHR tracing interpretation, as described by the National Institute of Child Health and Human Development (NICHD).7,8
