Tele-education in a telemedicine environment: implications for rural health care and academic medical centers.

Over 50 million people in the United States (about 20% of the population) live in rural areas, but only 9% of the nation's physicians practice in rural communities. It is difficult to recruit and retain rural health care practitioners, partly because of issues relating to professional isolation. New and enhanced telecommunications links between community and academic hospitals show promise for reducing this isolation and enhancing lifelong learning opportunities for rural health care providers. This paper will explore some of the issues involved in using interactive video (telemedicine) networks to transmit continuing medical education programming from an academic center to multiple rural hospitals. Data from a recent University of Iowa survey of the state's health educators will be presented as one approach to assessing the health care marketplace for the deployment of tele-education services.

Academic Medical Centers

Outreach education to improve quality of rural ICU care. Results of a randomized trial.

This study tests whether an outreach educational program tailored to institutional specific patient care practices would improve the quality of care delivered to mechanically ventilated intensive care unit (ICU) patients in rural hospitals. The study was conducted as a randomized control trial using 20 rural Iowa hospitals as the unit of analysis. Twelve randomly selected hospitals received an outreach educational program. After review of the medical records of eligible patients, a multidisciplinary team of intensive care unit specialists from an academic medical center delivered an educational program with content specific to the findings and capacity of the hospital. The outcome measures included patient care processes, patient morbidity and mortality outcomes, and resource use. Results indicated that the outreach program significantly improved many patient care processes (lab work, nursing, dietary management, ventilator management, ventilator weaning). The program marginally reduced hospital ventilator days. Both total length of stay and ICU length of stay fell markedly in the intervention group (by an average of 3.2 and 2.1 d, respectively), while the control group fell only 0.6 and 0.3 d, respectively. However, these effects did not reach statistical significance. Unfortunately, the program had no detectable effects on the clinical outcomes of mortality or nosocomial events. We conclude that an outreach program of this type can effectively improve processes of care in rural ICUs. However, improving processes of care may not always translate into improvement of specific outcomes.

Nurses' perceptions of why medication administration errors occur.

Nurses play a key role in medication administration in hospital settings. Five categories of reasons for medication errors were identified in a survey of 1,384 nurses. These categories include physician, systems, pharmacy, individual, and knowledge-related factors. In this article, issues surrounding the occurrence and prevention of medication errors are discussed.

A performance comparison of communication links between rural hospitals and a digital health sciences library.

BACKGROUND: Rural physicians need access to digital health sciences libraries (DHSLs) that is easy and reasonably rapid. The goal of this project was to study rural hospitals' access to a DHSL on the Internet, by comparing differing access speeds with differing costs and their acceptability for retrieving text, image, and video information in a DHSL. METHODS: DHSL system response time was measured at three different times during the day over three different types of network connections (T1, Frame Relay, Modem). Text, image, and video information was retrieved. Costs were determined for installation and operation of the different types of network connections. RESULTS: System response times were consistent at the three different testing times for each media type retrieved by each of the three network connection types. System response times for text retrieval met literature standards for all connections. Image retrieval met literature standards for T1 and Frame relay connections. No connection met literature standards for video retrieval. CONCLUSIONS: High speed access to DHSLs is preferable; Frame relay connections provide substantively similar service as T1 connections at less cost. However, access via modem to a DHSL can provide access to the majority of information--text--in a DHSL with an acceptable system response time.

Barriers to rural physician use of a digital health sciences library.

BACKGROUND: Rural physicians need access to quality medical information, but accessing information is difficult in rural settings. Digital health sciences libraries (DHSLs) offer the potential to make information more accessible to rural physicians. A telemedicine network was deployed to six rural hospitals in Iowa. Computers were installed allowing access to a DHSL and training sessions were held. The purpose of this study was to examine the barriers to use of a DHSL by rural physicians. METHODS: Approximately one year after deployment of the telemedicine network, physicians were surveyed using a modified critical incident technique. RESULTS: Seventy percent of the eligible physicians responded and 33% had used the DHSL. Primary barriers included insufficient training, being too time consuming to use, and distance of computers from physicians' practice sites. Non-DHSL users cited the difficulty of using the DHSL as their greatest barrier, while DHSL users cited the quality of the information resources. CONCLUSIONS: This study identifies a number of barriers that exist to rural physicians use of a DHSL. Potential solutions to these barriers are discussed. DHSLs will finally reach their potential when they can be delivered by easy to use handheld computers seamlessly integrated into the rural physician's workflow.

Health care providers' perceptions of telemedicine services.

OBJECTIVE: To assess the level of consensus among the administrative and health care leaders at rural Iowa hospitals regarding service gaps and priorities for developing telemedicine services. METHODS: In the summer of 1994, a survey was conducted of all rural hospital chief executive officers, chiefs of medical staffs, and directors of nursing in Iowa concerning their perceptions of telemedicine services. RESULTS: With the exception of teleradiology, few clinical specialties received high ratings as areas of need or priorities for the development of telemedicine. There was a general lack of agreement among respondents from the same hospital on such priorities. In contrast, respondents expressed higher priorities for the development of telemedicine-based educational services. CONCLUSIONS: The interest in teleradiology is consistent with the fact that teleradiology has been more thoroughly tested for medical efficacy than other telemedicine applications. Continuing medical education may represent another potential for widespread successful telemedicine application. Financial issues were reported as the greatest barriers to the development of telemedicine systems.

Trends and implications of visiting medical consultant outpatient clinics in rural hospital communities.

The emergence of visiting consultant clinics (VCC) represents an unstudied but potentially important mechanism for importing specialty physician services into rural areas. An analysis of five years of one state's VCC experience reveals a substantial increase in both availability and geographic accessibility. This study documents the market's response to the oversupply and hypercompetition among urban-based physician specialists. Patterns of VCC growth have varied markedly for different specialties.

Economic Competition

Adjusting measures of physician availability to reflect importation of physician services into rural areas.

Recent changes in the organization and delivery of physician services in rural areas suggest the need to update how physician availability is viewed and measured. The objective of this study was to empirically examine the effect of rural hospitals contracting with outside physicians for part or all of their emergency room coverage, and the use of urban specialists to staff outpatient clinics, on measures used to assess physician availability. Based on data from one rural state, the findings demonstrate the importance of adjusting for the importation of physician services into rural areas.

Developing a cooperative provider-based statewide peer review service: early experience.

The purpose of this study was to demonstrate the feasibility of a model of overcoming local barriers to physician peer review through development of a statewide provider-based physician peer review service. For this purpose, the cooperative demonstration project of the Institute for Quality Healthcare, The University of Iowa and The Robert Wood Johnson Foundation, was used. A consortium of 43 Iowa hospitals developed a physician peer review service utilizing a pool of physician reviewers from member hospitals. Thirty-six peer reviews were conducted in 23 different hospitals by 37 different reviewers throughout the state of Iowa in the first 2 years of operation. Reviews of surgical specialists, psychiatrists, and psychiatric services were requested most frequently. The satisfaction of hospitals with the physician peer review service has thus far been gratifying. The long-term financial viability of the physician peer review service has yet to be demonstrated. This cooperative organizational model of a provider-based physician peer review service may be reproducible and valuable to health care providers in other parts of the United States.

Considerations in establishing visiting consultant clinics in rural hospital communities.

Establishing specialty clinics staffed by visiting medical consultants is one way that rural hospitals can increase local access to specialty care. This example of private sector-driven regionalization of health care services typically involves an agreement among urban specialists, rural hospitals, and local primary care physicians. The urban-based physicians provide limited on-site specialty services in the rural community for patients who are referred by local physicians or self-refer to the specialty clinics. The trend toward formalization of regional relationships across large geographic areas prompts both opportunity and need for careful consideration of visiting specialty clinic arrangements in rural hospital communities. This article delineates advantages and disadvantages associated with the development of Visiting Consulting Clinics (VCC) along with some ¿ground rules¿ to consider when establishing this type of service.

The role of peer review in a health care organization driven by TQM/CQI.

BACKGROUND: Many health care organizations have embraced the philosophy and tools of total quality management (TQM) and continuous quality improvement (CQI) without overt linkage to existing peer review processes. Achieving total quality in an organization requires that both peer review and TQM/CQI improvement processes be effectively used. EXAMPLES: Three ways of linking peer review and TQM/CQI include: 1) coordinating TQM/CQI and peer review quality improvement initiatives whenever possible; 2) expanding the focus of peer review to include assessment of the processes and systems within which the clinician functions; and 3) linking peer review and TQM/CQI improvement processes to address behavioral and attitudinal issues having economic roots.

Cost-Benefit Analysis

Using comparative clinical and economic outcome information to profile physician performance.

This paper presents strategies and empirical examples of comparative physician profiling under conditions of limited patient sample sizes and varying patient severity. A method by which clinical and cost outcomes may be evaluated simultaneously is also presented. Physician economic and clinical performance are compared using data abstracted from nine hospitals into the MedisGroups clinical information management system for inpatients treated from July, 1990 through June, 1992. The main outcome measures are comparative total and ancillary adjusted charges, and morbidity status. Results suggest that objective comparative outcome data provide useful information to assist in evaluating physician performance. A simultaneous comparison of clinical outcomes and adjusted charges identifies physicians who experience favorable outcomes at lower charges, as well as those who have higher charges and/or poorer outcomes. Strategies outlined in this paper may be of value to clinicians, governing boards, and third party payors. These strategies may be used to assist with privileging and other peer review activities when pursued proactively within a Continuous Quality Improvement framework to improve care.

Understanding patient-centered care in the context of total quality management and continuous quality improvement.

BACKGROUND: Implementing patient-centered care (PCC) requires a fundamental shift in thinking-from how to best provide a wide variety of independent services to how to effectively combine individual service components into an integrated health care experience that meets patient needs and preferences. DISCUSSION: PCC attempts to improve patient care by organizationally and physically moving selected service functions such as basic laboratory, pharmacy, admitting/discharge, medical records, housekeeping, and material support services to patient care areas, thus effecting an organizational restructuring. PCC creates teams composed of multiskilled or cross-trained individuals capable of providing more of the services directly on the patient care unit. Extensive redesign of the basic work processes as proposed by PCC advocates may result in significant changes in employee job scope, task responsibilities, professional autonomy, and reporting relationships. From the employee's perspective such changes may be neither warranted nor welcomed. Therefore, critical PCC implementation issues include obtaining employee buy-in and establishing appropriate incentive structures to facilitate the desired changes. How does PCC fit in with the popular improvement philosophies of total quality management (TQM) and continuous quality improvement (CQI)? Inherent within TQM and CQI is the belief that it is wiser to maximize efforts to design a product or process to be right the first time and to minimize resources devoted to inspection and repair caused by poor processes. PCC builds upon previous TQM/CQI health care efforts by focusing on ways to reduce the white space handoff problem by examining what, if any, changes in underlying structures and processes may be required. In the PCC hospital, TQM/CQI can function as intended, as a methodology for examining and improving the process of care and patient-care outcomes, regardless of internal departmental or profession-based organizational boundaries. CONCLUSION: For hospitals to remain competitive in today's rapidly changing environment, it is becoming necessary to reevaluate both how they are organized and how their work processes have been designed and controlled. The groundwork already laid by TQM/CQI initiatives will facilitate the more fundamental and long-lasting improvements derived from the redesign of the patient-care unit as prescribed by the goals of PCC.

Hospital Restructuring

Contracting for emergency room coverage by rural hospitals.

Obtaining adequate physician availability remains a challenge to many rural communities. To ensure 24-hour emergency room physician coverage, many rural hospitals contracted for emergency room services from out-of-area and/or local physician. Survey findings for 99 rural and rural referral Iowa hospitals addressing the nature, extent, and cost of contracting physician coverage of the emergency room are presented. While nearly two-thirds of the hospitals reported contracting for at least some emergency room coverage, the extent and costs of contracts vary widely. Advantages and disadvantages of contracting for emergency room services are discussed.

Respiratory rate predicts cardiopulmonary arrest for internal medicine inpatients.

OBJECTIVE: To assess whether vital sign measurements could identify internal medicine patients at risk for cardiopulmonary arrest. DESIGN: Retrospective case-control study comparing 72 hours of pre-arrest vital sign measurements with 72 hours of vital sign measurements for patients from the same units who did not experience cardiopulmonary arrest. SETTING: Twelve non-intensive care internal medicine units at a large midwestern academic medical center. PATIENTS: Cases included all 59 inpatients who had experienced cardiopulmonary arrest between May 1989 and December 1990; patients who were designated do-not-resuscitate (DNR) or had less than 72 hours of vital sign recordings were excluded. Controls included 91 inpatients without cardiopulmonary arrest who were matched for units and who had 72 hours of vital sign recordings. RESULTS: The occurrence of one or more respiratory rates > 27 breaths per minute over a 72-hour period had a sensitivity of 0.54 and a specificity of 0.83 (odds ratio = 5.56, 95% CL = 2.67-11.49) in predicting cardiopulmonary arrest. Other respiratory rate thresholds were also predictive of arrest. The ability of respiratory rate to predict arrest was stronger in units with high incidences of arrest relative to units with low incidences, for example, in units for the management of gastrointestinal disease (sensitivity = 1.00, specificity = 0.86) and renal disease (sensitivity = 0.69, specificity = 0.87). Respiratory rate remained a significant predictor (p < 0.001) after controlling for patient age and gender. Pulse rate and blood pressure were not predictive of cardiopulmonary arrest. CONCLUSIONS: Using elevated respiratory rates as a signal for focused diagnostic studies and therapeutic interventions in internal medicine patients may be useful in reducing the incidence of subsequent cardiopulmonary arrest, and lowering associated morbidity and mortality.

Overcoming the barriers to implementation of TQM/CQI in hospitals: myths and realities.

Many health care organizations are attempting to rapidly implement total quality management (TQM) and continuous quality improvement (CQI) philosophies and concepts. In the case of hospitals, a number of issues resulting from traditional organizational design and management practices as well as the characteristics of health care professionals pose significant challenges to rapid implementation. Recognizing and developing strategies to address these challenges, along with realizing that TQM and CQI represent viable processes for conducting organizational "preventive maintenance," may help in changing the focus of quality assessment and enhancement initiatives from processes that are "broken" to processes that should be "fixed" before they "break." This article discusses strategies for overcoming some of the major barriers and challenges to successful TQM and CQI implementation to the hospital setting.

Evaluating the validity of blood glucose monitoring strip interpretation by experienced users.

This study examined interpretations of blood glucose monitoring strips (BGMS) by patients and registered nurses (RNs) experienced in strip use. Visual interpretations of whole and bisected BGMS were compared with readings obtained with a reflectance meter. For whole strips, statistically significant differences were found when mean values of patient interpretations were compared with two of the three RNs and the meter. A significant difference was found between the average meter values and those for a third RN. When bisected strips were interpreted, a significant interaction effect was found between reader and strip condition. The RNs systematically underestimated bisected strips when compared with whole strips, whereas patients consistently underestimated both whole and bisected strips. The findings support the need for development of quality assurance monitors to evaluate users of patient self-care technologies such as BGMS.

Analysis of Variance

Methods for estimating days of hospitalization due to nosocomial infections.

While there is little agreement at the individual patient level of analysis, estimates of mean NI-attributed days of stay for the two methods were essentially the same. The lack of agreement at the individual patient level may reflect fundamental differences in the methods used to derive these estimates: incorporation of noninfected patient data versus exclusive reliance on data from infected patients; and, focus on length of stay rather than the actual care being received. The potential advantages of the AEP-based method include the following: 1) all patients with NI can be included in developing estimates; 2) estimates are based on the care provided rather than simple length of stay differences; 3) data on which to form the NI-day estimates are readily available in the medical record; 4) the AEP is a validated and commonly used utilization review instrument; 5) the AEP-based method has acceptable reliability; 6) this method is designed to provide individual and group estimates of NI-attributed days; 7) because every day of stay is reviewed, additional information is available, which results in greater precision of study of the development, diagnosis, and treatment of the NI relative to the other care that originally brought the patient into the hospital. The AEP-based method for estimating NI-days is a promising alternative to the historical cohort approach. Additional applications of this approach are encouraged to further assess its reliability,validity, and additional information yield.
