Incidence of gastrointestinal bleeding with hydrocortisone use in neonates and infants less than three months of age in the neonatal intensive care unit.

OBJECTIVE: The objective of this study was to determine the incidence of hydrocortisone-associated gastrointestinal bleeding (GIB) in infants <3 months and compare rates with or without stress ulcer prophylaxis. STUDY DESIGN: Retrospective cohort study of NICU patients <3 months who received hydrocortisone for hypotension. Three logistic regressions were conducted for adjusted associations between GIB, necrotizing enterocolitis (NEC), or infection and clinical characteristics. RESULTS: Of 233 patients included, 54 (23.2%) received SUP; the majority (96.3%) received histamine-2 receptor antagonists. Median postmenstrual and postnatal age at hydrocortisone initiation was 33.3 weeks and 2 days. GIB occurred in 22 patients (9.4%), with no difference in GIB (11.1% versus 8.9%, p = 0.632) or SUP-associated adverse effects (50.0% versus 52.0%, p = 0.80) with and without SUP. SUP was not associated with GIB, NEC, or infection when controlling for confounders. CONCLUSION: GIB occurred in 9.4% of patients. SUP did not provide benefit for GIB prevention and was not associated with increased risk of adverse effects.

Exploring Pharmacy Students' Leadership Styles Using the 5 Voices Assessment.

OBJECTIVE: Leadership development assessments are a critical component of student pharmacists' understanding and development of effective team strategies. METHODS: The 5 Voices tool, developed by GiANT Worldwide, was incorporated into the leadership curriculum across 2 colleges of pharmacies for second-year Doctor of Pharmacy (PharmD) students. One public land-grant institution administers the assessment in the fall semester during a 2-h class session as part of a leadership elective leadership course and a private liberal arts institution distributes the 5 Voices assessment to all students during a 1-h spring semester required course. RESULTS: Responses from 456 PharmD students were included in the analysis, with 159 (34.9%) and 297 (65.1%) coming from the University of Minnesota and Drake University, respectively. Overall, 49.1% of PharmD students had nurturer as their foundational (first) voice. No differences were found in the distribution of first voices between institutions. The PharmD data are higher than the nurturer population-level average (43%). CONCLUSION: Introducing students to the 5 Voices assessment provides an opportunity for them to gain a better understanding of what they can contribute to a team. In addition, because nurturer is a dominant voice, this understanding can help provide appreciation for other voices necessary for team development.

The relationship and interdependence of auditory thresholds, proposed behavioural measures of hidden hearing loss, and physiological measures of auditory function.

OBJECTIVES: Standard diagnostic measures focus on threshold elevation but hearing concerns may occur independently of threshold elevation - referred to as "hidden hearing loss" (HHL). A deeper understanding of HHL requires measurements that locate dysfunction along the auditory pathway. This study aimed to describe the relationship and interdependence between certain behavioural and physiological measures of auditory function that are thought to be indicative of HHL. DESIGN: Data were collected on a battery of behavioural and physiological measures of hearing. Threshold-dependent variance was removed from each measure prior to generating a multiple regression model of the behavioural measures using the physiological measures. STUDY SAMPLE: 224 adults in the United States with audiometric thresholds ≤65 dB HL. RESULTS: Thresholds accounted for between 21 and 60% of the variance in our behavioural measures and 5-51% in our physiological measures of hearing. There was no evidence that the behavioural measures of hearing could be predicted by the selected physiological measures. CONCLUSIONS: Several proposed behavioural measures for HHL: thresholds-in-noise, frequency-modulation detection, and speech recognition in difficult listening conditions, are influenced by hearing sensitivity and are not predicted by outer hair cell or auditory nerve physiology. Therefore, these measures may not be able to assess threshold-independent hearing disorders.

Social Media Authentication and Users' Assessments of Health Information: Random Assignment Survey Experiment.

BACKGROUND: In an effort to signal the authenticity of user accounts, social networking sites (SNSs) such as Facebook and X, formerly known as Twitter, use visual heuristics (blue checkmarks) to signify whether accounts are verified. While these verification badges are generally well recognized (and often coveted) by SNS users, relatively little is known about how they affect users' perceptions of accuracy or their likelihood of engaging with web-based information. This is particularly true in the case of information posted by medical experts and health care professionals. OBJECTIVE: This study aims to use an experimental survey design to assess the effect of these verification badges on SNS users' assessments of information accuracy as well as their proclivity to recirculate health information or follow verified medical experts in their social network. METHODS: A survey experiment using random assignment was conducted on a representative sample of 534 adult SNS users in Florida, United States. A total of 2 separate experimental scenarios exposed users to vaccine-related posts from verified medical experts on X. In each case, the original post contained a platform-issued verification badge (treatment group), which was subsequently edited out of the image as an experimental control. For each scenario, respondents were randomly assigned to either the treatment or control group, and responses to 3 follow-up questions were assessed through a series of chi-square analyses and 2 logit regression models. Responses were fielded using a stratified quota sampling approach to ensure representativeness of the state's population based on age, sex, race, ethnicity, and political affiliation. RESULTS: Users' assessments of information accuracy were not significantly impacted by the presence or absence of verification badges, and users exposed to the experimental treatment (verification badge) were not any more likely to repost the message or follow the author. While verification badges did not influence users' assessments or subsequent behaviors, reliance on social media for health-related information and political affiliation were substantial predictors of accuracy assessments in both experimental scenarios. In scenario 1, which included a post addressing COVID-19 vaccine efficacy, users who relied on social media "a great deal" for health information were 2 times more likely to assess the post as accurate (odds ratio 2.033, 95% CI 1.129-3.661; P=.01). In scenario 2, which included a post about measles vaccines, registered Republicans were nearly 6 times less likely to assess the post as accurate (odds ratio 0.171, 95% CI 0.097-0.299; P<.001). CONCLUSIONS: For health professionals and medical experts wishing to leverage social networks to combat misinformation and spread reliable health-related content, account verification appears to offer little by way of added value. On the basis of prior research, other heuristics and communication strategies are likely to yield better results.

Toward parametric Bayesian adaptive procedures for multi-frequency categorical loudness scaling.

A series of Bayesian adaptive procedures to estimate loudness growth across a wide frequency range from individual listeners was developed, and these procedures were compared. Simulation experiments were conducted based on multinomial psychometric functions for categorical loudness scaling across ten test frequencies estimated from 61 listeners with normal hearing and 87 listeners with sensorineural hearing loss. Adaptive procedures that optimized the stimulus selection based on the interim estimates of two types of category-boundary models were tested. The first type of model was a phenomenological model of category boundaries adopted from previous research studies, while the other type was a data-driven model derived from a previously collected set of categorical loudness scaling data. An adaptive procedure without Bayesian active learning was also implemented. Results showed that all adaptive procedures provided convergent estimates of the loudness category boundaries and equal-loudness contours between 250 and 8000 Hz. Performing post hoc model fitting, using the data-driven model, on the collected data led to satisfactory accuracies, such that all adaptive procedures tested in the current study, independent of modeling approach and stimulus-selection rules, were able to provide estimates of the equal-loudness-level contours between 20 and 100 phons with root-mean-square errors typically under 6 dB after 100 trials.

Public perceptions of artificial intelligence in healthcare: ethical concerns and opportunities for patient-centered care.

BACKGROUND: In an effort to improve the quality of medical care, the philosophy of patient-centered care has become integrated into almost every aspect of the medical community. Despite its widespread acceptance, among patients and practitioners, there are concerns that rapid advancements in artificial intelligence may threaten elements of patient-centered care, such as personal relationships with care providers and patient-driven choices. This study explores the extent to which patients are confident in and comfortable with the use of these technologies when it comes to their own individual care and identifies areas that may align with or threaten elements of patient-centered care. METHODS: An exploratory, mixed-method approach was used to analyze survey data from 600 US-based adults in the State of Florida. The survey was administered through a leading market research provider (August 10-21, 2023), and responses were collected to be representative of the state's population based on age, gender, race/ethnicity, and political affiliation. RESULTS: Respondents were more comfortable with the use of AI in health-related tasks that were not associated with doctor-patient relationships, such as scheduling patient appointments or follow-ups (84.2%). Fear of losing the 'human touch' associated with doctors was a common theme within qualitative coding, suggesting a potential conflict between the implementation of AI and patient-centered care. In addition, decision self-efficacy was associated with higher levels of comfort with AI, but there were also concerns about losing decision-making control, workforce changes, and cost concerns. A small majority of participants mentioned that AI could be useful for doctors and lead to more equitable care but only when used within limits. CONCLUSION: The application of AI in medical care is rapidly advancing, but oversight, regulation, and guidance addressing critical aspects of patient-centered care are lacking. While there is no evidence that AI will undermine patient-physician relationships at this time, there is concern on the part of patients regarding the application of AI within medical care and specifically as it relates to their interaction with physicians. Medical guidance on incorporating AI while adhering to the principles of patient-centered care is needed to clarify how AI will augment medical care.

Exploring the Utility and Fairness of a Multi-institutional Situational Judgment Test.

OBJECTIVE: To pilot a situational judgment test (SJT) developed to assess empathy, integrity, and teamwork and explore differences in performance between first-year (P1) and fourth-year (P4) student pharmacists based on gender, race or ethnicity, and geographical region. METHODS: An SJT was developed to assess empathy, integrity, and teamwork, using best practices. The SJT was piloted tested with P1 and P4 student pharmacists at 5 institutions. Scores were adjusted for elevation and scatter to minimize the subgroup differences in response styles. RESULTS: The unadjusted mean SJT scores for P1 and P4 student pharmacists were 79.7 % and 80.7 %, respectively. The adjusted scores for P1 and P4 student pharmacists were 86.3 % and 87.2 %, respectively. Small differences were observed across institutions which can likely explained by multiple factors. The mean scores were higher among students who were older, female, identified as White, and spoke English as their first language. The subgroup differences persisted even after adjusting scores for elevation and scatter. CONCLUSION: Performance on an SJT designed to assess empathy, integrity, and teamwork was similar to others in the literature; however, differences in performance were observed across subgroups. Additional research is needed to determine whether these differences reflect test bias or other possible factors.

Toward Automating Diagnosis of Middle- and Inner-ear Mechanical Pathologies With a Wideband Absorbance Regression Model.

OBJECTIVES: During an initial diagnostic assessment of an ear with normal otoscopic exam, it can be difficult to determine the specific pathology if there is a mechanical lesion. The audiogram can inform of a conductive hearing loss but not the underlying cause. For example, audiograms can be similar between the inner-ear condition superior canal dehiscence (SCD) and the middle-ear lesion stapes fixation (SF), despite differences in pathologies and sites of lesion. To gain mechanical information, wideband tympanometry (WBT) can be easily performed noninvasively. Absorbance , the most common WBT metric, is related to the absorbed sound energy and can provide information about specific mechanical pathologies. However, absorbance measurements are challenging to analyze and interpret. This study develops a prototype classification method to automate diagnostic estimates. Three predictive models are considered: one to identify ears with SCD versus SF, another to identify SCD versus normal, and finally, a three-way classification model to differentiate among SCD, SF, and normal ears. DESIGN: Absorbance was measured in ears with SCD and SF as well as normal ears at both tympanometric peak pressure (TPP) and 0 daPa. Characteristic impedance was estimated by two methods: the conventional method (based on a constant ear-canal area) and the surge method, which estimates ear-canal area acoustically.Classification models using multivariate logistic regression predicted the probability of each condition. To quantify expected performance, the condition with the highest probability was selected as the likely diagnosis. Model features included: absorbance-only, air-bone gap (ABG)-only, and absorbance+ABG. Absorbance was transformed into principal components of absorbance to reduce the dimensionality of the data and avoid collinearity. To minimize overfitting, regularization, controlled by a parameter lambda, was introduced into the regression. Average ABG across multiple frequencies was a single feature.Model performance was optimized by adjusting the number of principal components, the magnitude of lambda, and the frequencies included in the ABG average. Finally, model performances using absorbance at TPP versus 0 daPa, and using the surge method versus constant ear-canal area were compared. To estimate model performance on a population unknown by the model, the regression model was repeatedly trained on 70% of the data and validated on the remaining 30%. Cross-validation with randomized training/validation splits was repeated 1000 times. RESULTS: The model differentiating between SCD and SF based on absorbance-only feature resulted in sensitivities of 77% for SCD and 82% for SF. Combining absorbance+ABG improved sensitivities to 96% and 97%. Differentiating between SCD and normal using absorbance-only provided SCD sensitivity of 40%, which improved to 89% by absorbance+ABG. A three-way model using absorbance-only correctly classified 31% of SCD, 20% of SF and 81% of normal ears. Absorbance+ABG improved sensitivities to 82% for SCD, 97% for SF and 98% for normal. In general, classification performance was better using absorbance at TPP than at 0 daPa. CONCLUSION: The combination of wideband absorbance and ABG as features for a multivariate logistic regression model can provide good diagnostic estimates for mechanical ear pathologies at initial assessment. Such diagnostic automation can enable faster workup and increase efficiency of resources.

Estimating Tiotropium Wasted Doses After Adding Revefenacin to an Inpatient Formulary: A Single-Center Cross-Sectional Study.

Introduction: Revefenacin is a once-daily nebulized long-acting muscarinic antagonist (LAMA). Revefenacin is supplied as single-use nebulized vials, which may be preferable and less costly for hospital and health-system pharmacies to dispense versus multidose tiotropium inhalers. Estimates of LAMA multidose inhaler wasted doses remains unknown. Methods: This was a single-center descriptive cross-sectional study conducted between January 1 2021 and December 31 2021. Adult patients 18 years and older admitted to a 500-bed academic medical center in the southern United States and were ordered multidose tiotropium packages or single-use revefenacin vials during the study period were included. Results: Among 602 inpatients, there were 705 LAMA orders: 541 tiotropium (76.7%) and 164 revefenacin (23.3%). Four hundred ninety-five tiotropium orders (91.5%) wasted between 20% and 90% of multidose packages. Approximately $24,000 tiotropium doses were wasted versus single-use revefenacin vials. Conclusion: Multidose inhalers of tiotropium dispensed to hospitalized patients contributed to wasted doses compared to nebulized single-use revefenacin vials. Opportunities exist to minimize wasted doses of multidose long-acting inhalers dispensed to hospitalized patients.

Belief in misinformation and acceptance of COVID-19 vaccine boosters: A survey analysis.

Objective: This study examines the impact of misinformation belief on the willingness of American adults to receive ongoing COVID-19 vaccine boosters. Methods: A representative survey of 600 adults in the state of Florida was fielded in August of 2023. For this study, responses were analyzed for the 443 previously vaccinated respondents in that sample using both descriptive and inferential statistical methods. Results: Among previously vaccinated individuals, belief in misinformation remained relatively high. 49% of respondents believe that COVID-19 vaccines contain a live strain of the virus, and roughly 40% believe that vaccines can cause you to "get sick" with COVID-19. Belief in misinformation was associated with a statistically significant decrease in the likelihood of receiving ongoing vaccine boosters, ceteris paribus. Conclusion: While confidence in public health guidelines is the most compelling determinant of vaccine acceptance, misinformation continues to undermine vaccination efforts. Addressing common myths about COVID-19 vaccines may help to improve booster shot acceptance among previously vaccinated Americans. Innovation: Throughout the COVID-19 pandemic, health professionals and public health agencies have been forced to innovate in real-time, as digital platforms have fueled the spread of viral misinformation. This study aims to inform these efforts by exploring and deepening our understanding of the impact that belief in misinformation has on vaccination behaviors.

Variability in opioid conversion calculators in critically ill children transitioned from fentanyl to hydromorphone.

PURPOSE: Opioid conversion calculators (OCCs) are used to convert between opioids. The purpose of this study was to describe the variability in OCC results in critically ill children transitioned from fentanyl to hydromorphone infusions. METHODS: This was a descriptive, retrospective study. Seventeen OCCs were identified and grouped into 6 groups (groups 1-6) based on the equianalgesic conversions. The OCCs were used to calculate the hydromorphone rate in critically ill children (<18 years) converted from fentanyl to hydromorphone. Information from a previous study on children stabilized on hydromorphone (defined as the first 24-hour period with no change in the hydromorphone rates, <3 hydromorphone boluses administered, and 80% of State Behavior Scale scores between 0 and -1) were utilized. The primary objective was to compare the median hydromorphone rates calculated using the 17 OCCs. The secondary objective was to compare the percent variability of the OCC-calculated hydromorphone rates to the stabilization rate. RESULTS: Seventeen OCCs were applied to data on 28 children with a median age and hydromorphone rate of 2.4 years and 0.08 mg/kg/h, respectively. The median hydromorphone rate calculated using the 17 OCCs ranged from 0.06 to 0.12 mg/kg/h. Group 3 and group 6 OCCs resulted in a calculated hydromorphone rate that was higher than the stabilization rate in 96% and 75% of patients, respectively. Use of group 4 and group 5 OCCs resulted in a calculated hydromorphone rate that was lower than the stabilization rate in 64% and 75% of patients, respectively. CONCLUSION: Given the considerable variability of OCCs, caution should be used when applying OCCs to critically ill children.

Delirium Assessment Treatment Strategies in Critically Ill Pediatric Patients: A Pediatric Pharmacy Association Practice-Based Research Network Survey Study.

OBJECTIVES: The purpose of this study was to describe overall screening, prevention, and treatments for pediatric delirium at various neonatal intensive care units (NICUs), cardiac intensive care units (CICUs), and pediatric intensive care units (PICUs) from the Pediatric Pharmacy Association (PPA) membership. The primary objective was to identify the number of respondents that had a defined delirium-based protocol. The secondary objectives included identification of delirium assessment tools used, first- and second-line delirium treatment options, and monitoring practices for antipsychotics for delirium management. METHODS: A cross-sectional questionnaire was distributed to PPA members from February 8, 2022, to March, 25, 2022. Comparisons between the NICUs, PICUs, and CICUs were conducted by using chi-square tests, with a priori p value of <0.05. RESULTS: The questionnaire was completed by 84 respondents at 62 institutions; respondents practiced in the PICU or mixed PICU (n = 48; 57.1%), CICU (n = 13; 15.5%), and NICU (n = 23; 27.4%). Sixty-one respondents (72.6%) noted their units routinely screen for delirium, and there was a significant difference between the respondents of different units that use a delirium scoring tool (p < 0.01). Only 33 respondents (39.3%) had a defined delirium protocol, and there was no difference between units (p = 0.31). The most common agents used for delirium treatment were quetiapine and risperidone. There was variability in the monitoring used between respondents, but the majority (n = 74; 88%) monitor electrocardiograms to assess the corrected QT interval, but practice variability existed. CONCLUSIONS: Most respondents did not have a defined delirium protocol. Variations were noted in the treatment options and monitoring for critically ill pediatric patients with delirium.

Effect of Phytonadione on Correction of Coagulopathy in Pediatric Patients With Septic Shock.

OBJECTIVES: The purpose of this study was to evaluate phytonadione in children with septic shock with disseminated intravascular coagulopathy (DIC). The primary objective was to identify the number of patients with an international normalized ratio (INR), defined as ≤1.2, following phytonadione. Secondary objectives were to compare patients who achieved a normalized INR versus those with INR >1.2 and to determine factors associated with a normalized INR. METHODS: A retrospective study of children <18 years of age receiving phytonadione from October 1, 2013, to August 31, 2020, with a diagnosis of septic shock, were included. Data collection included demographics, phytonadione regimen, INR values, Pediatric Index of Mortality 2 (PIM2) and Pediatric Risk of Mortality III (PRISM III) scores, fresh frozen plasma (FFP) and cryoprecipitate use. A logistic regression model and generalized linear model were used to explore factors associated with a normalized INR and evaluate phytonadione dosing. RESULTS: Data for initial phytonadione course for 156 patients were evaluated. Sixty-six (42.3%) patients had a normalized INR. Most patients (n = 145; 92.9%) received ≤3 phytonadione doses, with the largest reduction in INR occurring after the second dose. In the logistic regression model, baseline INR, FFP, cryoprecipitate, vasopressors, PIM2, PRISM III, or cumulative phytonadione dose were not associated with achieving a normalized INR. CONCLUSIONS: Less than half of patients achieved a normalized INR. The median cumulative dose of phytonadione and receipt of FFP or cryoprecipitate was not associated with an increased odds of a normalized INR. Future studies are needed to further explore phytonadione use in children with sepsis-induced coagulopathy.

Opening the Black Box: Agreement and Reliability of a Situational Judgment Test Across Multiple Institutions.

OBJECTIVE: The primary objective of this study was to examine the levels of agreement and reliability of a situational judgment test (SJT) using a diverse pool of pharmacy practice faculty as subject matter experts. Secondary aims included analyses to build support for test validity and fairness. METHODS: An SJT containing 18 scenarios and 118 responses assessing empathy, integrity, and teamwork was developed and delivered to pharmacy practice faculty at 5 schools of pharmacy across the United States. Reliability was assessed by examining internal consistency, inter-rater reliability, and split-half reliability. Only responses which attained an inter-rater agreement>0.7 were included in the final version of the SJT. All responses were scored using a near-miss system, allowing higher scores for answers more closely aligned with the key, which was determined by the faculty who completed the SJT. Test fairness was reported using descriptive statistics. RESULTS: Thirty-nine faculty across the 5 participating institutions completed the SJT. The final version of the SJT included 105 responses, achieving an inter-rater agreement of>0.7 (inter-rater reliability of 0.98). Split-half reliability was 0.72. The average score was 85.7%, and no differences in performance were observed based on demographic characteristics. CONCLUSION: An SJT designed to assess empathy, integrity, and teamwork achieved reasonable levels of reliability among pharmacy practice faculty across the United States, and the results provided initial support for test validity and fairness. These results support a pilot to assess this SJT among students representing multiple institutions.

Breakthrough COVID-19 infections and perceived vaccine effectiveness.

INTRODUCTION: While SARS-CoV-2 vaccines provide significant protection against severe COVID-19 illness, breakthrough infections have sparked confusion among patients about the effectiveness of vaccination. It's unclear if (or to what extent) breakthrough infection experiences impact public perceptions of COVID-vaccine effectiveness, though the answer may have significant implications for public health communications and ongoing vaccine acceptance. METHODS: We conducted a survey of 2,500 adults in the United States (February 27 - March 9, 2023) in order to better understand the relationship between breakthrough COVID-19 infections and perceived vaccine effectiveness. Survey respondents were selected using a stratified, quota sampling approach to ensure representativeness; analysis was conducted on responses from 1,928 participants who received a COVID-19 vaccine. FINDINGS: Among those who tested positive for COVID-19 after being vaccinated, 21.18 % said that COVID-19 vaccines had been "less effective" than they initially expected, compared with 10.0 % of those who did not experience any breakthrough infections (X2 = 75.551; φ = 0.198; p ≤ 0.001). Those who experienced their own breakthrough infection were 1.37 times less likely to report perceived vaccine efficacy, while those whose family members experienced a breakthrough infection were 1.64 times less likely to report the same, ceteris paribus. The largest effect was observed among those who experienced both a personal and familial breakthrough infection. This group was almost two times less likely to describe COVID-19 vaccines as "very effective". DISCUSSION: Breakthrough infections correlated with lower overall levels of perceived vaccine effectiveness, even after accounting for demographic and political considerations. Moving forward, public officials and health professionals should work proactively to ensure that breakthrough infections are understood in the broader context of overall vaccine effectiveness.

Metabolic and Sensory Components of Age-Related Hearing Loss: Associations With Distortion- and Reflection-Based Otoacoustic Emissions.

Age-related hearing loss is difficult to study in humans because multiple genetic and environmental risk factors may contribute to pathology and cochlear function declines in older adults. These pathologies, including degeneration of the stria vascularis, are hypothesized to affect outer hair cells responsible for active cochlear amplification of low-level sounds. Otoacoustic emission (OAE) measures are used to quantify the energy added to the traveling wave in cochlear amplification, which typically weakens with increased pure-tone thresholds and for older individuals. Thus, the current study evaluated two OAE measures for individuals with different components of age-related hearing loss. We examined two retrospective adult lifespan datasets (18 to 89+ years of age) from independent sites (Medical University of South Carolina and Boys Town National Research Hospital), which included demographics, noise history questionnaires, distortion-product otoacoustic emissions (DPOAE), and cochlear reflectance (CR). Metabolic and sensory estimates of age-related hearing loss were derived from the audiograms in each dataset, and then tested for associations with DPOAE and CR. The results showed that metabolic estimates increased for older participants and were associated with lower overall DPOAE and CR magnitudes across frequency (i.e., lower fitted intercepts). Sensory estimates were significantly higher for males, who reported more positive noise histories compared to females and were associated with steeper negative across-frequency slopes for DPOAEs. Although significant associations were observed between OAE configurations, DPOAEs appeared uniquely sensitive to metabolic estimates. The current findings suggest that distortion-based measures may provide greater sensitivity than reflection-based measures to the components of age-related hearing loss.

Melatonin Use in Infants Admitted to Intensive Care Units.

OBJECTIVES: Sleep deprivation is a risk factor for delirium development, which is a frequent complication of intensive care unit admission. Melatonin has been used for both delirium prevention and treatment. Melatonin safety, efficacy, and dosing information in neonates and infants is lacking. The purpose of this study was to describe melatonin use in infants regarding indication, dosing, efficacy, and safety. METHODS: This descriptive, retrospective study included infants <12 months of age admitted to an intensive care unit receiving melatonin. Data collection included demographics, melatonin regimen, sedative and analgesic agents, antipsychotics, and delirium-causing medications. The primary objective was to identify the melatonin indication and median dose. The secondary objectives included change in delirium, pain, and sedation scores; change in dosing of analgesic and sedative agents; and adverse event identification. Wilcoxon signed rank tests and linear mixed models were employed with significance defined at p < 0.05. RESULTS: Fifty-five patients were included, with a median age of 5.5 months (IQR, 3.9-8.2). Most (n = 29; 52.7%) received melatonin for sleep promotion. The median body weight-based dose was 0.31 mg/kg/dose (IQR, 0.20-0.45). There was a statistical reduction in cumulative morphine equivalent dosing 72 hours after melatonin administration versus before, 17.1 versus 21.4 mg/kg (p = 0.049). No adverse events were noted. CONCLUSIONS: Most patients (n = 29; 52.7%) received melatonin for sleep promotion at a median dose was 0.31 mg/kg/dose. Initiation of melatonin was associated with a reduction of opioid exposure; however, there was no reduction in pain/sedation scores.

Impact of Fluoroquinolone Susceptibility Suppression on Discharge Prescribing for Acute Uncomplicated Cystitis.

Background: Fluoroquinolones (FQs) are associated with adverse effects and increasing resistance. However, uncomplicated cystitis remains a frequent reason for FQ use. Selective reporting involves withholding susceptibilities for select antimicrobial agents on microbiology reports, in hopes of dissuading use by providers. The purpose of this study was to investigate the impact of FQ susceptibility suppression on discharge prescribing for hospitalized patients with uncomplicated cystitis. Methods: This retrospective quasi-experimental analysis was conducted among adult patients at a 350-bed academic medical center. Its aim was to compare the incidence of FQ prescribing for cystitis at hospital discharge, one year before and after implementation (1 March 2017-31 March 2019) of a policy to suppress FQ urinary susceptibility results for pansusceptible Klebsiella spp and Escherichia coli. FQ appropriateness and risk factors for FQ use were also examined. Results: There was a relative risk reduction of 39% in discharge FQ prescribing when adjusted for discharge team (adjusted risk ratio, 0.61; 95% CI, .40-.93). Almost all FQ use was inappropriate, largely due to organisms' susceptibility to a guideline-preferred agent (n = 61). In multivariate analysis, odds ratios of discharge FQ prescribing were 0.22 (95% CI, .12-.39) for insured patients, 0.43 (95% CI, .21-.86) for patients with antibiotic allergy, and 57.8 (95% CI, 13.7-244) for those receiving inpatient FQ. Discharge from a medicine team was protective against discharge FQ prescribing. Conclusions: With multidisciplinary inpatient medicine services and avoidance of inpatient FQ use, suppression of FQ susceptibilities on pansusceptible urine isolates for Klebsiella spp and E coli may represent an attractive strategy for antibiotic stewardship at hospital discharge.

Diagnosis Disclosure and Peer-to-Peer Information Seeking Among COVID-19-Infected Social Media Users: Survey of US-Based Adults.

BACKGROUND: Research examining online health communities suggests that individuals affected by chronic health conditions can obtain valuable information and social support through participation in peer-to-peer web-based information exchanges, including information sharing and seeking behaviors. The risks and rewards of these same behaviors in the case of acute illnesses, such as COVID-19, are less well understood, though there is reason to believe that individuals with COVID-19 and other acute illnesses may accrue similar benefits. OBJECTIVE: This study examines the propensity of American adults to disclose and discuss their COVID-19 diagnosis and symptoms on social media while actively infected with the SARS-CoV-2 virus, as well as to engage in peer-to-peer information seeking in order to better understand the illness that they are experiencing. Additionally, this study seeks to identify the motivations for these behaviors as well as their subsequent impacts on perceived social connectedness and health anxiety in patients with COVID-19. METHODS: We conducted a representative survey of 2500 US-based adults using a sample purchased through an industry-leading market research provider. Participants were selected through a stratified quota sampling approach to ensure a representative sample of the US population. Balanced quotas were determined (by region of the country) for gender, age, race, ethnicity, and political affiliation. Responses were analyzed from 946 participants who reported having an active social media account and testing positive for COVID-19 at least once since the start of the pandemic. RESULTS: The results show that only a small portion of social media users (166/946, 18%) chose to disclose and discuss their COVID-19 diagnosis while infected with the virus. However, among those who did, an overwhelming majority (206/251, 82%) said that doing so helped them feel more connected and supported while infected with the virus. A larger percentage of the 946 respondents (n=319, 34%) engaged in peer-to-peer information seeking while infected with COVID-19. Among those who did, a large majority (301/319, 94%) said that doing so was "helpful," but more than one-third (115/319, 36%) said that reading about other people's experiences made them "more worried" about having COVID-19, while 33% (108/319) said that it made them "less worried." Illness severity and political affiliation were significant predictors of both information sharing and seeking. CONCLUSIONS: The findings suggest that the benefits (and risks) associated with online health communities are germane to patients with acute illnesses such as COVID-19. It is recommended that public health officials and health care providers take a proactive approach to cultivating professionally moderated forums supporting peer-to-peer engagement during future outbreaks of COVID-19 and other acute illnesses in order to improve patient outcomes and promote social support and connectedness among infected patients.
