Work outcomes in public safety personnel after potentially traumatic events: A systematic review.

BACKGROUND: It is well documented that public safety personnel are exposed to potentially traumatic events (PTEs) at elevated frequency and demonstrate higher prevalence of trauma-related symptoms compared to the general population. Lesser studied to date are the organizational consequences of workplace PTE exposure and associated mental health outcomes such as acute/posttraumatic stress disorder (ASD/PTSD), depression, and anxiety. METHODS: The present review synthesizes international literature on work outcomes in public safety personnel (PSP) to explore whether and how PTE and trauma-related symptoms relate to workplace outcomes. A total of N = 55 eligible articles examining PTE or trauma-related symptoms in relation to work outcomes were systematically reviewed using best-evidence narrative synthesis. RESULTS: Three primary work outcomes emerged across the literature: absenteeism, productivity/performance, and costs to organization. Across n = 21 studies of absenteeism, there was strong evidence that PTE or trauma-related symptoms are associated with increased sickness absence. N = 27 studies on productivity/performance demonstrated overall strong evidence of negative impacts in the workplace. N = 7 studies on cost to organizations demonstrated weak evidence that PTE exposure or trauma-related mental health outcomes are associated with increased cost to organization. CONCLUSIONS: Based on available evidence, the experience of workplace PTE or trauma-related symptoms is associated with negative impact on PSP occupational functioning, though important potential confounds (e.g., organizational strain and individual risk factors) remain to be more extensively investigated.

Signs and Symptoms Clusters Among Patients With Acute Heart Failure: A Correlational Study.

BACKGROUND: Patients with acute heart failure present to the emergency department with a myriad of signs and symptoms. Symptoms evaluated in clusters may be more meaningful than those evaluated individually by clinicians. OBJECTIVE: Among emergency department patients, we aimed to identify signs and symptoms correlations, clusters, and differences in clinical variables between clusters. METHODS: Medical record data included adults older than 18 years, International Classification of Diseases, Tenth Revisions codes , and positive Framingham Heart Failure Diagnostic Criteria. Exclusion criteria included medical records with a ventricular assist device and dialysis. For analysis, correlation, and the Gower distance, the independent t test, Mann-Whitney U test, χ 2 test, and regression were performed. RESULTS: A secondary analysis was conducted from the data set to evaluate door-to-diuretic time among patients with acute heart failure in the emergency department. A total of 218 patients were included, with an average age of 69 ± 15 years and predominantly White (74%, n = 161). Two distinct symptom clusters were identified: severe and mild congestion. The severe congestion cluster had a more comorbidity burden compared with the mild congestion cluster, as measured by the Charlson Comorbidity index (cluster 1 vs cluster 2, 6 [5-7] vs 5 [4-6]; P = .0019). Heart failure with preserved ejection fraction was associated with the severe congestion symptom cluster ( P = .009), and heart failure with mildly reduced ejection fraction was associated with the mild congestion cluster ( P = .019). CONCLUSIONS: In conclusion, 2 distinct symptom clusters were identified among patients with acute heart failure. Symptom clusters may be related to ejection fraction or overall cardiac output and comorbidity burden.

Disparities in 30-Day Readmission Between Medicare/Medicaid and Private Insurance Among Patients With Heart Failure Screened for Cognitive Impairment.

BACKGROUND: Racial disparities exist among patients with heart failure (HF). HF is often comorbid with cognitive impairment. Appropriate self-care can prevent HF hospital readmissions but requires access to resources through insurance. Racial differences exist between insurance types, and this may influence the disparity between races and patients with HF and cognitive impairment. OBJECTIVE: The objectives of this study were to examine the relationships between insurance type and self-care stratified by race and to assess for differences in time-to-30-day readmission among patients with HF with cognitive impairment. METHODS: This is a secondary analysis of data collected among hospitalized patients with HF with cognitive impairment. Patients completed surveys on self-care (Self-Care of Heart Failure Index), HF knowledge (Dutch Heart Failure Knowledge Scale), depression (Geriatric Depression Scale), and social support (Enhancing Recovery in Coronary Heart Disease Social Support Inventory). Socioeconomic data were collected. Linear models were created to examine the relationships between insurance type and self-care by race. Kaplan-Meier curves and Cox regression were used to assess readmission. RESULTS: The sample of 125 patients with HF with cognitive impairment was predominantly Black (68%, n = 85) and male (53%, n = 66). The sample had either Medicare/Medicaid (62%, n = 78) or private insurance (38%, n = 47). Black patients with HF with cognitive impairment and private insurance reported higher self-care confidence compared with Black patients with HF with cognitive impairment and Medicare/Medicaid (P < .05). Medicare/Medicaid was associated with a higher frequency of 30-day readmission and a faster time-to-readmission. CONCLUSIONS: Patients with HF with cognitive impairment and Medicare/Medicaid insurance reported lower self-care confidence and more likely to be readmitted within 30 days.

Trends in NIH-funding to schools of nursing in the last 17 years.

BACKGROUND: Growing clinical demands, faculty retirements, fewer PhD-prepared graduates, and funding instability are challenges for nursing science. PURPOSE: The purpose of this analysis was to investigate National Institutes of Health (NIH) funding patterns in schools of nursing (SONs). METHODS: Data were extracted from the Blue Ridge Institute for Medical Research between 2006 and 2022. Growth modeling examined changes in funding over time between private and public SONs. DISCUSSION: In the last 17 years, NIH funding for SONs has risen nearly 25% but remains only 1% of the total NIH budget for extramural research. Overall, 109 (75%) of the SONs were public and 36 (25%) were private institutions. Regarding geography, 90% of the States received NIH funding except six: ID, ME, MS, NH, VT, and WY. Private SONs consistently received more funding than public SONs but the difference was only statistically significant in 2022. CONCLUSION: NIH funding has significantly increased to SONs, there is better geographic distribution but a funding disparity exists between public and private SONs.

An annotated ventricular tachycardia (VT) alarm database: Toward a uniform standard for optimizing automated VT identification in hospitalized patients.

BACKGROUND: False ventricular tachycardia (VT) alarms are common during in-hospital electrocardiographic (ECG) monitoring. Prior research shows that the majority of false VT can be attributed to algorithm deficiencies. PURPOSE: The purpose of this study was: (1) to describe the creation of a VT database annotated by ECG experts and (2) to determine true vs. false VT using a new VT algorithm created by our group. METHODS: The VT algorithm was processed in 5320 consecutive ICU patients with 572,574 h of ECG and physiologic monitoring. A search algorithm identified potential VT, defined as: heart rate >100 beats/min, QRSs > 120 ms, and change in QRS morphology in >6 consecutive beats compared to the preceding native rhythm. Seven ECG channels, SpO2 , and arterial blood pressure waveforms were processed and loaded into a web-based annotation software program. Five PhD-prepared nurse scientists performed the annotations. RESULTS: Of the 5320 ICU patients, 858 (16.13%) had 22,325 VTs. After three levels of iterative annotations, a total of 11,970 (53.62%) were adjudicated as true, 6485 (29.05%) as false, and 3870 (17.33%) were unresolved. The unresolved VTs were concentrated in 17 patients (1.98%). Of the 3870 unresolved VTs, 85.7% (n = 3281) were confounded by ventricular paced rhythm, 10.8% (n = 414) by underlying BBB, and 3.5% (n = 133) had a combination of both. CONCLUSIONS: The database described here represents the single largest human-annotated database to date. The database includes consecutive ICU patients, with true, false, and challenging VTs (unresolved) and could serve as a gold standard database to develop and test new VT algorithms.

Methodological correlates of variability in the prevalence of posttraumatic stress disorder in high-risk occupational groups: A systematic review and meta-regression.

BACKGROUND: Although numerous studies have reported on PTSD prevalence in high-risk occupational samples, previous meta-analytic work has been severely limited by the extreme variability in prevalence outcomes. METHODS: The present systematic review and meta-regression examined methodological sources of variability in PTSD outcomes across the literature on high-risk personnel with a specific focus on measurement tool selection. RESULTS: The pooled global prevalence of PTSD in high-risk personnel was 12.1% [6.5%, 23.5%], and was similar to estimates obtained in other meta-analytic work. However, meta-regression revealed that PTSD prevalence differed significantly as a function of measurement tool selection, study inclusion criteria related to previous traumatic exposure, sample size, and study quality. PTSD prevalence estimates also differed significantly by occupational group and over time, as has also been reported in previous work, though exploratory examination of trends in measurement selection across these factors suggests that measurement strategy may partially explain some of these previously reported differences. CONCLUSIONS: Our results highlight a pressing need to better understand the role of measurement strategies and other methodological choices in characterizing variable prevalence outcomes. Understanding the role of methodological variance will be critical for work attempting to reliably characterize prevalence as well as risk and protective factors for PTSD.

The Use of Interactive Technology to Improve Student Accuracy on Electrocardiographic Interpretation.

ABSTRACT: Electrocardiography (ECG) instruction relies heavily on memorization of interpretation rules and lacks opportunities for hands-on practice. Consequently, nursing students struggle with ECG interpretation. In an online undergradute nursing course, we implemented interactive technology to facilitate kinesthetic pedagogy. Accuracy was evaluated at midterm and during final assessments by two experts using a standardized rubric. Students who engaged with interactive technology at both assessments demonstrated consistent accuracy of ECG interpretation; students who did not failed to demonstrate consistent accuracy with ECG interpretation. Incorporating interactive technology to facilitate psychomotor learning may be essential in improving the accuracy of ECG interpretation.

Delays in Door-to-Diuretic Time and 1-Year Mortality Among Patients With Heart Failure.

BACKGROUND: Achieving prompt euvolemic state in heart failure (HF) is associated with reduced mortality. Time-sensitive metrics such as door-to-diuretic time , or the time between presentation and administration of intravenous diuretics, may be an important facilitator of achieving a faster euvolemic state and reducing mortality. OBJECTIVE: The aim of this study was to investigate whether reduced door-to-diuretic time was associated with lower odds of death among hospitalized patients with HF. METHODS: A retrospective chart review of patients with HF admitted to a medical center was performed between 2020 and 2021. Inclusion criteria were an International Classification of Diseases, 10th Revision code for HF with positive Framingham Criteria and the use of intravenous bolus furosemide. Exclusion criteria included ventricular assist devices, dialysis, and ultrafiltration therapy. Data collected from the medical records included demographics, echocardiography, staff notes, and medications. The end point was 1-year all-cause mortality. Descriptive statistics, t tests or median test, and multivariate logistic regression were used to describe the sample, evaluate group differences, and determine odds of mortality, respectively. RESULTS: Among 160 charts from patients with HF (age, 70 ± 14.4 years; 52%, n = 83, male; 53%, n = 85, ischemic cardiomyopathy; 83%, n = 134, New York Heart Association classes III-IV), 30% (n = 48) died within 1 year. The median diuretic dose was 40 mg (interquartile range, 20 mg), with a median time of administration of 247 minutes (4.12 hours) (interquartile range, 294 minutes to 4.9 hours). After covariate adjustment, prolonged door-to-diuretic time more than doubled (2.22; 95% confidence interval, 1.03-4.8; P = .04) the odds of 1-year mortality. CONCLUSIONS: On the basis of this sample of charts from older highly symptomatic patients with HF, delayed door-to-diuretic time was associated with significantly greater odds of 1-year all-cause mortality.

PREVALENCE AND PREDICTORS OF POSTTRAUMATIC STRESS DISORDER, DEPRESSION, AND ANXIETY IN PERSONNEL WORKING IN EMERGENCY DEPARTMENT SETTINGS: A SYSTEMATIC REVIEW.

BACKGROUND: Professionals working in the emergency department (ED) are regularly exposed to traumatic events. Rates of posttraumatic mental health conditions vary widely in the literature and there is no agreement that rates in ED staff are elevated relative to other populations. OBJECTIVE: We conducted a systematic review of international literature reporting prevalence of posttraumatic stress disorder (PTSD), depression, and anxiety in ED personnel to determine whether prevalence is elevated compared to the general community, and to evaluate convergent evidence across the literature for predictive factors. To our knowledge, there is no comprehensive review on this topic in the literature at this time. METHODS: Seven databases were searched for studies reporting rates of PTSD, depression, and anxiety in ED personnel. Two independent researchers screened studies and assessed quality using Munn's Prevalence Critical Appraisal Instrument. Best-evidence synthesis determined whether conditions demonstrated elevated prevalence compared to the general population of Canada, a conservative benchmark. RESULTS: Twenty-four studies from 12 countries and a combined sample size of 4768 were included. PTSD rates ranged from 0% to 23.6% (mean 10.47%), depression ranged from 0.7% to 77.1% (mean 24.8%), and anxiety rates ranged from 2.4% to 14.6% (mean 9.29%). Each condition was elevated compared to the general population. Sociodemographic variables were not consistent predictors. Elevated PTSD seemed most strongly related to workplace exposure and maladaptive coping. CONCLUSIONS: ED professionals have an elevated risk of experiencing PTSD, depression, and anxiety. Identification of organizational and workplace predictors are needed to inform interventions that will reduce risk and provide optimal treatment and management of PTSD, depression, and anxiety in ED settings.

Mindfulness for Outpatient Oncology Nurses: A Pilot Study.

This prospective pre-/posttest pilot studied a mindfulness-based stress reduction (MBSR) intervention first, to reduce self-reported stress and improve compassion satisfaction; and second, to reduce physiological indices of stress. Even small interventions of MBSR before a shift effectively reduces the physiological indices of stress and may help reduce compassion fatigue and burnout in nurses.

The prevalence of PTSD, major depression and anxiety symptoms among high-risk public transportation workers.

OBJECTIVE: Public transportation workers are exposed to higher levels of stress related to accidents, injuries, and person-under-train events when compared to other workers. This systematic review integrates the existing literature on mental health among high-risk public transportation workers to estimate the prevalence of post-traumatic stress disorder (PTSD), major depressive and anxiety symptoms following critical incidents while on duty. METHODS: This systematic review is part of a larger systematic review which examines mental health and work outcomes of individuals working in professions at high risk of critical incident exposure, i.e., high-risk professions. Articles were included if they measured the prevalence of PTSD, Major Depressive Disorder (MDD) and Anxiety Disorder (AD) in a transportation population following exposure to a major incident, for example, a person-under-a-train. RESULTS: Among the ten articles, all reported prevalence of PTSD which ranged from 0.73 to 29.9%. Four articles reported prevalence of depression among transportation workers exposed to a critical incident and prevalence outcomes ranged from 0.05 to 16.3%. Only two reported prevalence of anxiety from 1.3 to 13.9%. CONCLUSIONS: This literature reports that transportation workers are prone to involvement in traumatic accidents leading to higher rates of PTSD compared to the general population. Strategies to reduce transportation accidents and to provide transportation workers follow-up mental health support is needed for this vulnerable population.

An eye toward the future: Pressing questions for our discipline in today's academic and research climate.

This paper seeks to open a dialogue concerning the current trend in hiring non-nurse faculty (NNF) to tenure track positions in schools/colleges of nursing. The evolution of non-nurses as faculty, including a review of contemporary papers in affecting this trend, is offered. Three means of involving non-nurses in advancing our discipline are presented. The impact of the growing trend of NNF is discussed relative to the integrity of our discipline and effects on education. We conclude by suggesting a manner of proceeding and raise questions for furthering dialogue.

Systematic review of posttraumatic stress disorder in police officers following routine work-related critical incident exposure.

BACKGROUND: The prevalence of PTSD in police officers has been the subject of a large and highly variable empirical literature. The present systematic review evaluates the extant literature on PTSD in police officers using an international dataset. METHODS: We employed best-evidence narrative synthesis to evaluate whether PTSD prevalence in police is elevated in comparison to the general population of Canada (8%), which itself has a higher lifetime PTSD prevalence than many other regions and thus serves as a conservative standard of comparison. RESULTS: PTSD prevalence in police varied considerably across studies from 0% - 44% (M = 14.87%, Median = 9.2%). Despite this variability, strong evidence exists to suggest PTSD prevalence is elevated in police officers. Examination of possible sources of variability in prevalence outcomes highlighted substantial variability in outcomes due to the selection of measurement tool for assessing PTSD (e.g., DSM vs. IES). Examination of commonly-assessed predictive factors for PTSD risk across the literature showed that individual-difference factors (e.g., age, years of service) bear weak-to-nonexistent relationships with PTSD risk, while incident-specific factors (e.g., severity of exposure) are more strongly and consistently associated with PTSD prevalence. Organizational factors (e.g., low support from supervisor) are at present understudied but important possible contributors to PTSD risk. CONCLUSIONS: PTSD prevalence is elevated in police officers and appears most strongly related to workplace exposure. Measurement variability remains a critical source of inconsistencies across the literature with drastic implications for accurate detection of officers in need of mental health intervention.

Comparing an All-RN Unit to a Mixed-Skill Unit at a Hospital.

OBJECTIVE: The aim of this study was to assess the differences in patient complications as well as patient and staff satisfaction between a mixed-skill unit and an all-registered nurse (RN) unit. BACKGROUND: It is recognized that nursing care delivered by RNs results in better outcomes; however, more evidence is needed to support a change to an all-RN unit. METHODS: A mixed unit with RNs and unlicensed assistive personnel was compared with an all-RN unit. Each unit had similar resources. Patient complications and patient and staff satisfaction were measured. Patient complications were reported in terms of 1,000 patient days over the study period to minimize noise fluctuations; t test and χ compared means and frequencies, respectively. RESULTS: The all-RN unit had a lower prevalence of patient complications. Patients reported better pain management, and nurse explanation, and reported higher satisfaction on the all-RN unit. CONCLUSIONS: An all-RN unit provided superior outcomes compared with a mixed-skill unit without additional costs.

The Value of Using an Acuity Score for Neonatal Nursing Research.

The Score for Neonatal Acute Physiology (SNAP) is a physiological-based illness severity tool developed in 1993, and since that time, it has been revised to include SNAP-II Perinatal Extension (SNAPPE-II) for mortality risk assessment and SNAP-II to assess severity of illness. The purpose of this methodologically based article is to provide an overview of SNAP methodology and then to critically evaluate the feasibility and utility of SNAP-II in neonatal nursing research. The SNAP-II scoring measure is parsimonious and has been utilized in a variety of retrospective and prospective medical research with good results; yet, it is not often employed in nursing studies. For research purposes, the required data are readily obtainable from medical records, calculations can be performed via computer to reduce errors, and the resultant score is parsimonious and reproducible. SNAP-II has some limitations, however, and additional research is needed to further refine the scoring system. This methodological article outlines the strengths and limitations of SNAP-II and recommends the use of a severity score to better describe research samples for clinical benchmarking and comparative research. There is extensive interest in validating acuity scores for appropriate patient assignments. Rather than having established ratios, often established by law, nurses are interested in measuring patient acuity and appropriately assigning ratios based on patient needs.

Obesity and hypertension contribute to prolong QRS complex duration among middle-aged adults.

BACKGROUND: Obesity and hypertension are comorbid diseases, which influence cardiac structure, and are associated with increased risk for cardiovascular events. The QRS duration (QRSd) reflects ventricular depolarization, and increased QRSd is associated with poor cardiovascular outcomes. QRS duration may be influenced by obesity and HTN, and reflect the increased risk factor for poor cardiovascular outcomes. The purpose of this analysis was to assess the relations between obesity, hypertension, and the interaction between them on QRSd. METHODS: In this secondary data analysis, firefighters without documented cardiovascular disease in normal sinus rhythm were included. Twelve-lead 24-hr ECG Holter monitors measured mean QRSd. Body mass index (BMI) and resting blood pressure (BP) were measured and categorized. Univariate linear regression models were produced using BMI, BP, and the interaction between BMI and BP as factors associated with QRSd. Multivariate models adjusting for multiple covariates were also produced. RESULTS: Seventy-seven firefighters were included and most (89.4%) were overweight or obese. After covariate adjustment, BMI (p = 0.028), BMI categorization (p = 0.020), and the interaction between BMI and systolic BP (p = 0.021) were associated with prolong QRSd. CONCLUSIONS: Increased BMI and an interaction between BMI and systolic BP were independently associated with prolongation of the QRS complex. Determination of the underlying cardiac structures responsible prolongation of the QRSd is recommended for further research.

The role of heart rate variability, heart rate turbulence, and deceleration capacity in predicting cause-specific mortality in chronic heart failure.

BACKGROUND: The volume of regional denervated myocardium (D-M) on positron emission tomography has been recently suggested as a strong independent predictor of cause-specific mortality from sudden cardiac arrest (SCA) in chronic heart failure. We sought to evaluate whether ECG indices of global autonomic function predict risk of SCA to a similar degree as regional D-M. METHODS: Subjects enrolled in the Prediction of Arrhythmic Events using Positron Emission Tomography (PAREPET) study were included in this study. Patients completed a 24-hour Holter ECG at enrollment and were followed up at 3-month intervals. SCA events were adjudicated by two board-certified cardiologists. Other cardiovascular death events were classified as nonsudden cardiac death (NSCD). Eight measures of heart rate variability were analyzed: SDNN, RMSSD, low-frequency (LF) and high-frequency (HF) power, heart rate turbulence onset and slope, and acceleration and deceleration capacity. We used competing risk regression to delineate cause-specific mortality from SCA versus NSCD. RESULTS: Our sample included 127 patients (age 67 ±â€¯12, 92% male). After a median follow-up of 4.1 years, there were 22 (17%) adjudicated SCA and 18 (14%) adjudicated NSCD events. In multivariate Cox-regression, LF power was the only HRV parameter to predict time-to-SCA. However, in competing risk analysis, reduced LF power was preferentially associated with NSCD rather than SCA (HR = 0.92 [0.85-0.98], p = 0.019). CONCLUSION: Depressed LF power might indicate impaired vagal reflex, which suggests that increasing vagal tone in these patients would have a protective effect against NSCD beyond that achieved by the mere slowing of heart rate using ß-blockers.

Widened QRS-T Angle May Be a Measure of Poor Ventricular Stretch During Exercise Among On-duty Firefighters.

BACKGROUND: The spatial QRS-T angle is a measure of repolarization heterogeneity and may be a predictor of poor ventricular health. It is unknown whether a relationship exists between QRS-T angle and blood pressure (BP) during exercise. OBJECTIVE: The purpose of this study was to evaluate the potential relationship between QRS-T angle and BP during exercise, which may be indicative of ventricular stretch. METHODS: Ambulatory 12-lead 24-hour Holter electrocardiographic monitoring for QRS-T angle measurement was followed by exercise testing with BP (mm Hg) recordings taken preexercise, maximum achieved BP during exercise, and 2 minutes postexercise. Blood pressure recovery was calculated by subtracting the maximal and 2-minute postexercise BPs. Means (± standard deviation) and percentages are presented. Pearson correlations (r) among all QRS-T angles and all BP measures were performed. One-way analysis of variance was conducted on classification of QRS-T angle and all BP measures. RESULTS: One hundred eleven firefighters (95.5% male; mean age, 44 years) were included in this analysis. Twenty-seven percent of the firefighters had either a borderline (100°-139°) or widened (≥140°) QRS-T angle. Although the analysis of variance was not statistically significant, a near-statistically significant negative correlation existed between QRS-T angle and maximum diastolic BP (r = -0.190, P = .05), and a statistically significant relationship existed between QRS-T angle and postexercise diastolic BP (r = -0.261, P = .008). CONCLUSIONS: A negative correlation existed between QRS-T angle and maximal diastolic BP and postexercise diastolic BP. Lower maximum diastolic BP during and after exercise may be a sign of poor ventricular stretch. A widened spatial QRS-T angle may represent poor ventricular stretch.

Brief video intervention to teach firefighters the neurobiological basis of high risk alcohol use: A pilot study.

INTRODUCTION: Evidence-based information related to the neurobiological bases of alcohol use disorders has not been widely disseminated to individuals affected by alcohol use. The feasibility, acceptability, and effectiveness of the video, Alcohol and the Brain was assessed, guided by the three constructs of the transtheoretical model: processes of change, decisional balance, and self-efficacy. METHODS: This study examined the feasibility and acceptability of a brief video intervention and change in alcohol-related knowledge in a sample of urban firefighters (n = 11). The 20 min video was shown in a 45-min session of a Self-Management Wellness Program. A 10-item knowledge test was administered prior to and after the video and analyzed using a paired t-tests. RESULTS: This brief intervention was feasibly delivered with sufficient time for questions and answers in the firehouse. There was a high level of acceptability as reflected in the positive comments and the highly interactive discussion. There was a significant increase in knowledge from pre- to post-test (t = 7.7; p < 0.001). IMPLICATIONS FOR PRACTICE: Complex neuroscience can be translated for patients in the form of a video that is feasible and acceptable with significant increase in knowledge. The efficacy of this brief video intervention on alcohol-related and treatment-related outcomes needs to be established.

Essential Oils to Reduce Postoperative Nausea and Vomiting.

PURPOSE: The purpose of this study was to determine if using essential oil products for adult patients reduced the need for antiemetics for postoperative nausea and vomiting (PONV). DESIGN: A prospective and retrospective cross-sectional design using a convenience sample. METHODS: Double blinded to the type of essential oil, subjects randomly selected a nasal inhaler containing peppermint, ginger, or a combination of both. A prophylactic dose was given preoperatively, and during the postoperative period nausea was assessed using verbal descriptive scale. FINDINGS: Overall 322 same day surgical patients were analyzed (control group [n = 179] and intervention group [n = 143]). The intervention group had a greater history of PONV but received fewer doses of antiemetics postoperatively compared with the control group. There was no significant difference in the effectiveness of the three types of inhalers. CONCLUSIONS: Aromatherapy demonstrated a statistically significant (P < .05) reduction in the need for antiemetics to treat PONV.
