Use and outcomes of telemetry monitoring on a medicine service

Clinician Perspectives on Continuous Monitor Use in a Children's Hospital: A Qualitative Study

BACKGROUND AND OBJECTIVES

Variation in continuous cardiopulmonary monitor (cCPM) use across children's hospitals suggests preference-based use. We sought to understand how clinical providers make decisions to use cCPMs.

METHODS

We conducted a qualitative study using semi-structed interviews with clinicians (nurses, respiratory therapists [RTs], and resident and attending physicians) from 2 hospital medicine units at a children's hospital. The interview guide employed patient cases and open-ended prompts to elicit information about workflows and decision-making related to cCPM, and we collected basic demographic information about participants. We used an inductive approach following thematic analysis to code transcripts and create themes.

RESULTS

We interviewed 5 nurses, 5 RTs, 7 residents, and 7 attending physicians. We discovered that clinicians perceive a low threshold for starting cCPM, and this often occurred as a default action at admission. Clinicians thought of cCPMs as helping them cope with uncertainty. Despite acknowledging considerable flaws in how cCPMs were used, they were perceived as a low-risk intervention. Although RNs and RTs were most aware of the patient's current condition and number of alarms, physicians decided when to discontinue monitors. No structured process for identifying when to discontinue monitors existed.

CONCLUSIONS

We concluded that nurses, physicians, and RTs often default to cCPM use and lack a standardized process for identifying when cCPM should be discontinued. Interventions aiming to reduce monitor use will need to account for or target these factors.

Wearables alone will not eliminate failure to rescue

Surveys suggest that anaesthesiologists believe that continuous monitoring with wearables will lead to improved patient outcomes. However, evidence suggests that several critical factors, including timely recognition of physiological problems, the presence of a trained team to respond to the alerts, and that the alerts occur far in advance of the deterioration, are required before overall improvement can occur. Wearables alone will not change patients' outcomes, they must be implemented as part of a system change that takes advantage of the higher frequency observations that continuous monitoring provides.

Family Perspectives on Continuous Monitor Use in a Children's Hospital: A Qualitative Study

OBJECTIVES

Alarms from continuous cardiorespiratory and pulse oximetry monitors may contribute to parental anxiety and poor sleep during hospitalization, yet families also may find monitoring reassuring. Our objective was to understand how families perceive the utility, benefits, and harms of continuous monitoring.

METHODS

In this single-center qualitative study, we used semistructured interviews and direct observation. We enrolled families of patients of a variety of ages and clinical diagnoses. We extracted patient demographic information (age, diagnosis) from the health record. Semistructured interviews were recorded and transcribed. Detailed field notes were taken during observations. We used an inductive thematic approach to develop and refine codes that informed the development of themes.

RESULTS

We recruited 24 families and conducted 23 interviews and 9 observation sessions. Respiratory conditions (eg, bronchiolitis, asthma) were the most common reason for hospitalization. The hospitalized children covered a range of ages: <4 weeks (16%), 4 weeks to 6 months (20%), 7 months to 5 years (44%), and >5 years (20%); 55% had previously been hospitalized. Families expressed varying degrees of understanding the utility of monitors and often conducted their own assessments before notifying staff about alarms. Families expected monitoring, including negative effects like sleep disruption, as part of hospitalization. Families perceived the benefit of monitoring in context of previous hospital experiences, often seeing less benefit and worrying less about alarms in subsequent hospitalizations.

CONCLUSIONS

Family members continue to find reassurance from cardiorespiratory monitoring despite evidence that it offers limited benefit outside of the ICU setting. Parental perspectives should be addressed in future deimplementation efforts.

Empowering nurses and residents to improve telemetry stewardship in the academic care setting

AIMS AND OBJECTIVES

Inappropriate use of telemetry frequently occurs in the inpatient, non-intensive care unit setting. Telemetry practice standards have attempted to guide appropriate use and limit the overuse of this important resource with limited success. Clinical-effectiveness studies have thus far not included care settings in which resident-physicians are the primary caregivers.

METHODS

We implemented two interventions on general internal medicine units of an academic hospital. The first intervention, or nurse-discontinuation protocol, allowed nurses to trigger the discontinuation of telemetry once the appropriate duration had passed according to practice standards. The second intervention, or physician-discontinuation protocol, instituted a best-practice advisory that notified the resident-physician via the electronic medical record when the appropriate telemetry duration for each patient had elapsed and suggested termination of telemetry. Data collection spanned 8 months following the implementation of the nurse-discontinuation protocol and 12 months following the physician-discontinuation protocol.

RESULTS

During the control period, the average time spent on telemetry was 86.29 hours/patient/month. During the nurse-discontinuation protocol, patients spent, on average, 70.86 hours/patient/month on telemetry. During the physician-discontinuation protocol, patients spent, on average, 81.6 hours/patient/month on telemetry. During the nurse-discontinuation protocol, there was no significant change in the likelihood that a patient was placed on telemetry throughout their admission when compared with the control period. During the physician-discontinuation protocol, there was a significant decrease of 56.1% in the likelihood that a patient would be put on telemetry when compared with the control time period.

CONCLUSIONS

These findings expand our understanding of telemetry use in the academic care setting in which trainees serve as the primary caregivers. Furthermore, these findings represent an important addition to the telemetry and patient monitoring literature by demonstrating the impact that nurse-managed protocols can have on telemetry use and by highlighting effective strategies to improve telemetry use by physicians in training.

Telemetry Overuse and the Effect of Educational and Electronic Health Record-Based Interventions on an Academic Internal Medicine Ward

OBJECTIVES

Guidelines for appropriate use of telemetry recommend monitoring for specific patient populations; however, many hospitalized patients receive telemetry monitoring without an indication. Clinical data and outcomes associated with nonindicated monitoring are not well studied. The objectives of our study were to evaluate the impact of an education and an order entry intervention on telemetry overuse and to identify the diagnoses and telemetry-related outcomes of patients who receive telemetry monitoring without guidelines indication.

METHODS

A retrospective cohort study of hospitalized patients on internal medicine (IM) wards between 2015 and 2018 examining the effects of educational and order entry interventions at an academic urban medical center. A baseline cohort examining telemetry use was established. This was followed by the delivery of IM resident educational sessions regarding telemetry guidelines. In a subsequent intervention, the telemetry order entry system was modified with a constraint to require American Heart Association guidelines justification.

RESULTS

Across all of the cohorts, 51% (n = 141) of patients lacked a guidelines-specified indication. These patients had variable diagnoses. The educational intervention alone did not result in significant differences in telemetry use by IM residents. The order entry intervention resulted in a significant increase in the proportion of guidelines-indicated patients and a decrease in nonindicated patients on telemetry. No safety events were noted in any group.

CONCLUSIONS

A telemetry order entry system modification implemented following an educational intervention is more likely to reduce telemetry use than an educational intervention alone in IM resident practice. A variety of patients are monitored without evidence of need; therefore, the clinical impact of telemetry reduction is unlikely to be harmful.

Barriers and Facilitators to Guideline-Adherent Pulse Oximetry Use in Bronchiolitis

OBJECTIVE

Continuous pulse oximetry monitoring (cSpO2) in children with bronchiolitis does not improve clinical outcomes and has been associated with increased resource use and alarm fatigue. It is critical to understand the factors that contribute to cSpO2 overuse in order to reduce overuse and its associated harms.

METHODS

This multicenter qualitative study took place in the context of the Eliminating Monitor Overuse (EMO) SpO2 study, a cross-sectional study to establish rates of cSpO2 in bronchiolitis. We conducted semistructured interviews, informed by the Consolidated Framework for Implementation Research, with a purposive sample of stakeholders at sites with high and low cSpO2 use rates to identify barriers and facilitators to addressing cSpO2 overuse. Interviews were audio recorded and transcribed. Analyses were conducted using an integrated approach.

RESULTS

Participants (n = 56) included EMO study site principal investigators (n = 12), hospital administrators (n = 8), physicians (n = 15), nurses (n = 12), and respiratory therapists (n = 9) from 12 hospitals. Results suggest that leadership buy-in, clear authoritative guidelines for SpO2 use incorporated into electronic order sets, regular education about cSpO2 in bronchiolitis, and visual reminders may be needed to reduce cSpO2 utilization. Parental perceptions and individual clinician comfort affect cSpO2 practice.

CONCLUSION

We identified barriers and facilitators to deimplementation of cSpO2 for stable patients with bronchiolitis across children's hospitals with high- and low-cSpO2 use. Based on these data, future deimplementation efforts should focus on clear protocols for cSpO2, EHR changes, and education for hospital staff on bronchiolitis features and rationale for reducing cSpO2.

Cardiorespiratory and Pulse Oximetry Monitoring in Hospitalized Children: A Delphi Process

OBJECTIVES

Cardiorespiratory and pulse oximetry monitoring in children who are hospitalized should balance benefits of detecting deterioration with potential harms of alarm fatigue. We developed recommendations for monitoring outside the ICU on the basis of available evidence and expert opinion.

METHODS

We conducted a comprehensive literature search for studies addressing the utility of cardiorespiratory and pulse oximetry monitoring in common pediatric conditions and drafted candidate monitoring recommendations based on our findings. We convened a panel of nominees from national professional organizations with diverse expertise: nursing, medicine, respiratory therapy, biomedical engineering, and family advocacy. Using the RAND/University of California, Los Angeles Appropriateness Method, panelists rated recommendations for appropriateness and necessity in 3 sequential rating sessions and a moderated meeting.

RESULTS

The panel evaluated 56 recommendations for intermittent and continuous monitoring for children hospitalized outside the ICU with 7 common conditions (eg, asthma, croup) and/or receiving common therapies (eg, supplemental oxygen, intravenous opioids). The panel reached agreement on the appropriateness of monitoring recommendations for 55 of 56 indications and on necessity of monitoring for 52. For mild or moderate asthma, croup, pneumonia, and bronchiolitis, the panel recommended intermittent vital sign or oximetry measurement only. The panel recommended continuous monitoring for severe disease in each respiratory condition as well as for a new or increased dose of intravenous opiate or benzodiazepine.

CONCLUSIONS

Expert panel members agreed that intermittent vital sign assessment, rather than continuous monitoring, is appropriate management for a set of specific conditions of mild or moderate severity that require hospitalization.

'Utilization of telemetry monitoring for non-cardiac conditions in non-critical patients: what are the trends and perceptions amongst medical residents?'

Background & Objective

Current evidence shows that telemetry monitoring is commonly overutilized for 'non-cardiac' diseases such as COPD exacerbation, pneumonia, pulmonary embolism and sepsis. This issue has not been addressed clearly in the recent American Heart Association (AHA) guidelines and no standard recommendations on the use of telemetry in non-cardiac conditions exist; therefore, clinicians continue to make such decisions based on personal preferences.As medical residency is an important phase during which young physicians develop clinical skills and habits for their future practice, the aim of this study was to understand the prevalent trends related to inappropriate telemetry use amongst the medical residents at a community hospital and the associated factors which influence the use of telemetry monitoring in non-cardiac patients.

Methods

All the residents undergoing internal medicine training at a community hospital were surveyed with the help of a questionnaire regarding the utility of telemetry in non-critical patients admitted with non-cardiac conditions.

Results

Survey was completed by 37 residents. Analysis of the responses showed that despite the frequent use of telemetry in non-cardiac conditions, majority of the medical residents are unaware of the correct indications. Seventy-three percent choose 'continuous' telemetry when placing the order while only 16% (often or always) discontinue telemetry after 24 hours of uneventful use. Although 84% residents admitted that telemetry is overutilized, still 49% felt that it leads to better patient care while 70% considered it superior to frequent vitals monitoring for early detection of hemodynamic instability. Possible causes of inappropriate use included 'Lack of knowledge about the related literature' and 'Following trends set by the peers'.

Conclusion

Majority of the medical residents overutilize telemetry in non-cardiac conditions due to lack of knowledge, perceived sense of security and inappropriate trends set by their colleagues. In order to abolish these tendencies, we propose the provision of adequate educational resources to the clinical staff at every level along with other system-based strategies.

Monitoring the Use of Telemonitor: A Resident-run Quality Improvement Initiative Decreases Inappropriate Use of Telemonitor in a Community Hospital

Background Cardiac telemetry is an important tool to detect life-threatening conditions in hospitalized patients but is used widely and inappropriately. We sought to assess current usage and improve the appropriate use of telemetry in a community hospital. Methods We conducted a quality improvement project on patients who were admitted on telemetry floors between January and March 2017 (pre-intervention). The indication(s) and duration of telemonitor use, event(s) recorded on telemonitor and outcome of the event(s) were documented. A six-month educational intervention was undertaken and the effect of intervention was assessed among patients admitted between December 2017 and February 2018 (post-intervention). Results In the pre-intervention group, 329 patients qualified for the study, with a median age of 78 years. The post-intervention group had 383 qualified patients with a median age of 77 years. Mean duration of telemonitor use was four days in both groups. In the pre-intervention group, 54% had class I, 32% had class II, and 14% had class III indications. In post-intervention group, 46% had class I, 42% had class II, and 12% had class III indications. The educational intervention resulted in a trend towards less inappropriate use of telemetry, particularly in teaching service. Telemonitor events were recorded in 22 (7%) of the pre-intervention patients and 13 (4%) of the post-intervention group. Two patients died in the pre-intervention group and one in the post-intervention group from non-cardiac causes. Conclusion Our results highlight that change in practice requires sustained education interventions.

Nurse Responses to Physiologic Monitor Alarms on a General Pediatric Unit

BACKGROUND

Hospitalized children generate up to 152 alarms per patient per day outside of the intensive care unit. In that setting, as few as 1% of alarms are clinically important. How nurses make decisions about responding to alarms, given an alarm's low specificity for detecting clinical deterioration, remains unclear.

OBJECTIVE

Our objective was to describe how bedside nurses think about and act upon monitor alarms for hospitalized children.

DESIGN, SETTING, PARTICIPANTS

This was a qualitative study that involved the direct observation of nurses working on a general pediatric unit at a large children's hospital.

MEASUREMENTS

We used a structured tool that included predetermined categories to assess nurse responses to monitor alarms. Data on alarm frequency and type were pulled from bedside monitors.

RESULTS

We conducted 61.3 patient-hours of observation with nine nurses, in which we documented 207 nurse responses to patient alarms. For 67% of alarms heard outside of the room, the nurse decided not to respond without further assessment. Nurses most commonly cited reassuring clinical context (eg, medical team in room), as the rationale for alarm nonresponse. The nurse deemed clinical intervention necessary in only 14 (7%) of the observed responses.

CONCLUSION

Nurses rely on clinical and contextual details to determine how to respond to alarms. Few of the alarm responses in our study resulted in a clinical intervention. These findings suggest that multiple system-level and educational interventions may be necessary to improve the efficacy and safety of continuous monitoring.

Factors Influencing Use of Continuous Physiologic Monitors for Hospitalized Pediatric Patients

OBJECTIVES

Continuous physiologic monitors (CPMs) generate frequent alarms and are used for up to 50% of children who are hospitalized outside of the ICU. Our objective was to assess factors that influence the decision to use CPMs.

METHODS

In this qualitative study, we used group-level assessment, a structured method designed to engage diverse stakeholder groups. We recruited clinicians and other staff who work on a 48-bed hospital medicine unit at a freestanding children's hospital. We developed a list of open-ended prompts used to address CPM use on inpatient units. Demographic data were collected from each participant. We conducted 6 sessions to permit maximum participation among all groups, and themes from all sessions were merged and distilled.

RESULTS

Participants (n = 78) included nurses (37%), attending physicians (17%), pediatric residents (32%), and unit staff (eg, unit coordinator; 14%). Participants identified several themes. First, there are patient factors (eg, complexity and instability) for which CPMs are useful. Second, participants perceived that alarms have negative effects on families (eg, anxiety and sleep deprivation). Third, CPMs are often used as surrogates for clinical assessments. Fourth, CPM alarms cause anxiety and fatigue for frontline staff. Fifth, the decision to use CPMs should be, but is not often, a team decision. Sixth, and finally, there are issues related to the monitor system's setup that reduces its utility.

CONCLUSIONS

Hospital medicine staff identified patient-, staff-, and system-level factors relevant to CPM use for children who were hospitalized. These data will inform the development of system-level interventions to improve CPM use and address high alarm rates.

Appropriate utilisation of cardiac telemetry monitoring: a quality improvement project

For hospitals located in the United States, appropriate use of cardiac telemetry monitoring can be achieved resulting in cost savings to healthcare systems. Our institution has a limited number of telemetry beds, increasing the need for appropriate use of telemetry monitoring to minimise delays in patient care, reduce alarm fatigue, and decrease interruptions in patient care. This quality improvement project was conducted in a single academic medical centre in Kansas City, Kansas. The aim of the project was to reduce inappropriate cardiac telemetry monitoring on intermediate care units. Using the 2004 American Heart Association guidelines to guide appropriate telemetry utilisation, this project team sought to investigate the effects of two distinct interventions to reduce inappropriate telemetry monitoring, huddle intervention and mandatory order entry. Telemetry utilisation was followed prospectively for 2 years. During our initial intervention, we achieved a sharp decline in the number of patients on telemetry monitoring. However, over time the efficacy of the huddle intervention subsided, resulting in a need for a more sustained approach. By requiring physicians to input indication for telemetry monitoring, the second intervention increased adherence to practice guidelines and sustained reductions in inappropriate telemetry use.

Solving alarm fatigue with smartphone technology

Alarms were developed to improve patient safety, but alarm fatigue may put patients at higher risk for harm. This article recounts one acute care institution's search for a better alarm management solution using smartphone technology to replace its beeper-based system for telemetry alarm events.

Assessment of a Targeted Electronic Health Record Intervention to Reduce Telemetry Duration: A Cluster-Randomized Clinical Trial

IMPORTANCE

Physicians frequently use cardiac monitoring, or telemetry, beyond the duration recommended by published practice standards, resulting in "alarm fatigue" and excess cost. Prior studies have demonstrated an association between multicomponent quality improvement interventions and safe reduction of telemetry duration.

OBJECTIVE

To determine if a single-component intervention, a targeted electronic health record (EHR) alert, could achieve similar gains to multicomponent interventions and safely reduce unnecessary monitoring.

DESIGN, SETTING, AND PARTICIPANTS

This cluster-randomized clinical trial was conducted between November 2016 and May 2017 on the general medicine service of the Division of Hospital Medicine at the University of California, San Francisco Medical Center and included physicians of 12 inpatient medical teams (6 intervention, 6 control).

INTERVENTIONS

The EHR alert was randomized to half of the teams on the general medicine service. The alert displayed during daytime hours when physicians attempted to place an order for patients not in the intensive care unit whose telemetry order duration exceeded the recommended duration for a given indication.

MAIN OUTCOMES AND MEASURES

The primary outcome was telemetry monitoring hours per hospitalization, which was measured using time-stamped orders data from the EHR database. Physician responses to the alert were collected using EHR reporting tools. The potential adverse outcomes of rapid-response calls and medical emergency events were measured by counting the notes documenting these events in the EHR.

RESULTS

Of the 1021 patients included in this study, in the intervention arm, there was a mean (SD) age of 64.5 (18.9) and 215 (45%) were women; in the control arm, there was a mean (SD) age of 63.8 (19.1) and 249 (46%) were women. The 12 teams were stratified to 8 house-staff teams and 4 hospitalist teams, with 499 hospitalizations analyzed in the intervention arm and 567 hospitalizations analyzed in the control arm. The alert prompted a significant reduction in telemetry monitoring duration (-8.7 hours per hospitalization; 95% CI, -14.1 to -3.5 hours; P = .001) with no significant change in rapid-response calls or medical emergency events. The most common physician response to the alert was to discontinue telemetry monitoring (62% of 200 alerts).

CONCLUSIONS AND RELEVANCE

A targeted EHR alert can safely and successfully reduce cardiac monitoring by prompting discontinuation when appropriate. This single-component electronic intervention is less resource intensive than typical multicomponent interventions that include human resources.

Utilization of Continuous Cardiac Monitoring on Hospitalist-led Teaching Teams

Guidelines for continuous cardiac monitoring (CCM) have focused almost exclusively on cardiac diagnoses, thus limiting their application to a general medical population. In this study, a retrospective chart review was performed to identify the reasons that general medical patients, cared for on hospitalist-led inpatient teaching teams between April 2017 and February 2018, were initiated and maintained on CCM, and to determine the incidence of clinically significant arrhythmias in this patient population. The three most common reasons for telemetry initiation were sepsis (24%), arrhythmias (12%), and hypoxia (10%). Most patients remained on telemetry for more than 48 hours (62%) and a significant number of patients were on telemetry until they were discharged from the hospital (39%). Of the cumulative total of more than 20,573 hours of CCM provided to this patient population, 37% of patients demonstrated only normal sinus rhythm and 3% had a clinically significant arrhythmia that affected management.

Association of Implementation of Practice Standards for Electrocardiographic Monitoring With Nurses' Knowledge, Quality of Care, and Patient Outcomes: Findings From the Practical Use of the Latest Standards of Electrocardiography (PULSE) Trial

BACKGROUND

Although continuous electrocardiographic (ECG) monitoring is ubiquitous in hospitals, monitoring practices are inconsistent. We evaluated implementation of American Heart Association practice standards for ECG monitoring on nurses' knowledge, quality of care, and patient outcomes.

METHODS AND RESULTS

The PULSE (Practical Use of the Latest Standards of Electrocardiography) Trial was a 6-year multisite randomized clinical trial with crossover that took place in 65 cardiac units in 17 hospitals. We measured outcomes at baseline, time 2 after group 1 hospitals received the intervention, and time 3 after group 2 hospitals received the intervention. Measurement periods were 15 months apart. The 2-part intervention consisted of an online ECG monitoring education program and strategies to implement and sustain change in practice. Nurses' knowledge (N=3013 nurses) was measured by a validated 20-item online test, quality of care related to ECG monitoring (N=4587 patients) by on-site observation, and patient outcomes (mortality, in-hospital myocardial infarction, and not surviving a cardiac arrest; N=95 884 hospital admissions) by review of administrative, laboratory, and medical record data. Nurses' knowledge improved significantly immediately after the intervention in both groups but was not sustained 15 months later. For most measures of quality of care (accurate electrode placement, accurate rhythm interpretation, appropriate monitoring, and ST-segment monitoring when indicated), the intervention was associated with significant improvement, which was sustained 15 months later. Of the 3 patient outcomes, only in-hospital myocardial infarction declined significantly after the intervention and was sustained.

CONCLUSIONS

Online ECG monitoring education and strategies to change practice can lead to improved nurses' knowledge, quality of care, and patient outcomes.

Does this patient need telemetry? An analysis of telemetry ordering practices at an academic medical center

INTRODUCTION

The American Heart Association and Choosing Wisely campaign recommend guideline-based usage of telemetry. Inappropriate use leads to increased costs, alarm fatigue, and inefficient nursing care. This study assesses provider ordering practices for telemetry at a US-based academic hospital.

METHODS

This retrospective study includes all telemetry orders in the medicine and progressive care units from April 2014 to March 2015. Indications were grouped into categories per American Heart Association guidelines.

RESULTS

The top 3 cardiac indications included angina/acute coronary syndrome (35.3%), arrhythmias (19.7%), and heart failure (10.2%). However, noncardiac indications accounted for 20.2% of orders, including respiratory conditions (17.4%), infection (17.4%), substance abuse (14.0%), bleeding (12.4%), vital sign monitoring (10.4%), altered mental status (7.0%), and pulmonary embolus/deep vein thrombosis (7.0%).

CONCLUSIONS

One-fifth of patients were monitored on telemetry for noncardiac indications. We recommend further study on the benefits and risks of telemetry in these patients and systems-based changes for appropriate usage.

Health Informatics via Machine Learning for the Clinical Management of Patients

OBJECTIVES

To review how health informatics systems based on machine learning methods have impacted the clinical management of patients, by affecting clinical practice.

METHODS

We reviewed literature from 2010-2015 from databases such as Pubmed, IEEE xplore, and INSPEC, in which methods based on machine learning are likely to be reported. We bring together a broad body of literature, aiming to identify those leading examples of health informatics that have advanced the methodology of machine learning. While individual methods may have further examples that might be added, we have chosen some of the most representative, informative exemplars in each case.

RESULTS

Our survey highlights that, while much research is taking place in this high-profile field, examples of those that affect the clinical management of patients are seldom found. We show that substantial progress is being made in terms of methodology, often by data scientists working in close collaboration with clinical groups.

CONCLUSIONS

Health informatics systems based on machine learning are in their infancy and the translation of such systems into clinical management has yet to be performed at scale.

A multidisciplinary approach to reducing alarm fatigue and cost through appropriate use of cardiac telemetry

BACKGROUND

Alarm fatigue (AF) is a distressing factor for staff and patients in the hospital. Using cardiac telemetry (CT) without clinical indications can create unnecessary alarms, and increase AF and cost of healthcare. We sought to reduce AF and cost associated with CT monitoring.

METHODS

After implementing a new protocol for CT placement, data were collected on telemetry orders, alarms and bed cost for 13 weeks from 1 January 2015 through 31 March 2015. We also retrospectively collected data on the same variables for the 13 weeks prior to the intervention. A survey was administered to nurses to assess past and present perceptions of AF. Interventions included protocol creation and education for participants.

RESULTS

At baseline, 77% of patients were monitored with CT. A total of 145 (31%) order discrepancies were discovered during data collection, of which 72% had no indication for CT, so CT was discontinued. The other 28% had indications, so orders were placed. A total of 8336 alarms were recorded during 4 weeks of data collection, of which 333 (4%) were classified as true actionable alarms. Postintervention data showed 67% CT assignment with 10% reduction in CT usage, with no increase in mortality (p<0.001 and >0.05, respectively). A 42% cost reduction was achieved after adjusting the patient status. Nurses reported 27% perceived reduction in AF. One-year follow-up revealed that 69% of patients were being monitored by CT, and the rate of order discrepancies due to lack of indication was 9%.

CONCLUSION

All hospital units may benefit from the protocols created during this study. If applied appropriately, these protocols can lead to reduced AF and cost per episode of care.

Non-critical care telemetry and in-hospital cardiac arrest outcomes

BACKGROUND

Telemetry is increasingly used to monitor hospitalized patients with lower intensities of care, but its effect on in-hospital cardiac arrest (IHCA) outcomes in non-critical care patients is unknown.

HYPOTHESIS

Telemetry utilization in non-critical care patients does not affect IHCA outcomes.

METHODS

A retrospective cohort analysis of all patients in non-critical care beds that experienced a cardiac arrest in a university-affiliated teaching hospital during calendar years 2011 and 2012 was performed. Data were collected as part of AHA Get With the Guidelines protocol. The independent variable and exposure studied were whether patients were on telemetry or not. Telemetry was monitored from a central location. The primary endpoint was return of spontaneous circulation (ROSC) and the secondary end point was survival to discharge.

RESULTS

Of 123 IHCA patients, the mean age was 75±15 and 74 (61%) were male. 80 (65%) patients were on telemetry. Baseline demographics were similar except for age; patients on telemetry were younger with mean age of 70.3 vs. 76.8 in the non-telemetry group (p=0.024). 72 patients (60%) achieved ROSC and 46 (37%) achieved survival to discharge. By univariate analysis, there was no difference between patients that had been on telemetry vs. no telemetry in ROSC (OR=1.13, p=0.76) or survival to discharge (OR=1.18, p=0.67). Similar findings were obtained with multivariate analysis for ROSC (0.91, p=0.85) and survival to discharge (OR=0.92, p=0.87).

CONCLUSIONS

The use of cardiac telemetry in non-critical care beds, when monitored remotely in a central location, is not associated with improved IHCA outcomes.

Evaluation of the appropriateness and outcome of in-hospital telemetry monitoring

The American Heart Association classifies monitored patients into 3 categories. The aims of this study were to (1) investigate how patients are assigned according to the American Heart Association classification, (2) determine the number and type of arrhythmic events experienced by these patients, and (3) describe subsequent changes in management. A prospective observational study design was used. All patients assigned to telemetry during a 3-month period were consecutively enrolled in our study. Data were collected 24/7. Only arrhythmias that might require a change in management were recorded. Monitor watchers at the central monitoring station completed a standard data sheet assessing 64 variables. These data, as well as medical records, were reviewed by the investigator. Overall, 1,194 patients were included. Eighteen percent of the patients were assigned to American Heart Association class I (monitoring indicated), 71% to class II (monitoring may be of benefit), and 11% to class III (monitoring not indicated). The overall arrhythmia event rate was 33%. Forty-three percent of class I patients, 28% of class II patients, and 47% of class III patients experienced arrhythmia events. Change in management occurred in 25% of class I patients, 14% of class II patients, and 29% of class III patients. Although the number of class III indications should have been reduced, nearly 1/2 of class III patients experienced arrhythmia events and 1/3 of them received management changes. This outcome challenges existing guidelines. In conclusion, most patients in this study were monitored appropriately, according to class I and II indications.
