Evaluation of Medications Used for Hospitalized Patients With Sleep Disturbances: A Frequency Analysis and Literature Review

Relationship between the presence of meaning in life and sleep quality: A moderated chain-mediation model

Sleep is a vital component of health; however, sleep issues are particularly prominent among college students. Identifying protective factors for sleep among college students is of paramount importance. To investigate the mechanisms behind the association between the presence of meaning in life (PML) and sleep quality, we conducted two questionnaire surveys (separated by an interval of 6 months) with 5660 college students to collect longitudinal data. The results show that PML predicted sleep quality and that this relationship was influenced by the mediating effect of depression and the chain mediating effect of coping style and depression; further, the search for meaning in life played a moderating role in the chain mediation model. This study offers new theoretical perspectives on the protective factors of sleep quality and provides empirical insights useful for improving sleep health among college students.

Optimizing Sleep Disorder Management in Hospitalized Patients: Practical Approach for Healthcare Providers

PURPOSE

To provide a comprehensive review of sleep disturbances in hospitalized patients, focusing on a case-based approach to illustrate the multifaceted nature of this clinical challenge.

METHOD

An extensive review of related literature was conducted to determine the common causes of sleep disturbances in hospitalized patients, such as environmental, medical, psychological, and physiological factors. The case of Mrs. Z was used to illustrate how these factors interact in a clinical setting.

FINDINGS

The study revealed a high prevalence of sleep disturbances in hospitalized patients, which can lead to significant adverse outcomes. A multidisciplinary approach involving physicians, nurses, pharmacists, and other healthcare professionals is essential to effectively manage sleep disorders due to the interplay of various factors. Nonpharmacological interventions are fundamental to a comprehensive sleep management plan. Pharmacotherapy may sometimes be necessary to improve sleep quality and duration.

CONCLUSION

Health professionals can significantly enhance the sleep quality of hospitalized piatients by understanding the value of sleep and providing evidence-based strategies for improvement. In return, this improves patient outcomes, reduces healthcare costs, and advances general patient satisfaction.

Elucidating the Effects of Sleep Deprivation: Exploring fMRI Imaging Biomarkers to Analyze Brain Functions Related to Insomnia

Background

This study aimed to propose functional magnetic resonance imaging (fMRI) imaging biomarkers for the diagnosis of insomnia by examining the brain maps of young and old people during sleep deprivation (SD).

Materials and Methods

A total of 50 healthy individuals were selected in two groups, including the young group: 17 people (20 to 30 years) and the elderly group: 23 people (65 to 75 years), who were involved in a 1-month period of SD, so that during the experiment they woke up 3 hours earlier than usual. Insomnia and sleepiness questionnaires were collected from these individuals (OpenfMRI website). Independent component analysis (ICA) processing was performed using the Generalized Intelligent Framework for Tutoring (GIFT) toolbox on old and young people's data. Correlations between clinical variables and imaging were performed to extract insomnia biomarkers with a significance level of P = 0.05.

Results

In the dynamic range variable, the difference in the effect of insomnia between the two groups was significant in areas such as the inferior occipital gyrus (IOG), superior temporal gyrus (STG), and posterior cingulate (PC). The fractional amplitude of low-frequency fluctuation (fALFF) variable in the anterior cingulate and precuneus areas, as well as the spatial map variable in areas such as the inferior semilunar lobule, anterior cingulate, subcallosal gyrus, and middle temporal gyrus (MTG) between the two groups, was significantly different (P = 0.05).

Conclusion

Based on the results of this study, brain activity map in sleep-deprived people has a significant change in some brain areas and this effect is different in old and young adults.

Addressing Sleep Disorders in Psychiatry: Comparing the Use of Melatonin, Trazodone, and Doxepin

Introduction Sleep disorders are prevalent among psychiatric patients, and pharmacological treatments such as melatonin, trazodone, and doxepin are commonly prescribed. This study aimed to assess the efficacy and acceptability of these three medications in improving sleep quality and reducing daytime drowsiness in psychiatric patients. Methodology A total of 175 psychiatric patients with sleep disturbances participated in this cohort study at the Abbas Institute of Medical Sciences, Muzaffarabad, Pakistan.Participants were initially randomized, with assignments subsequently reviewed and confirmed by physicians based on clinical considerations, into one of three therapy groups: doxepin, trazodone, or melatonin. They were monitored over the course of six months, from February to July 2024. The Pittsburgh Sleep Quality Index (PSQI) was used to measure sleep quality, the Epworth Drowsiness Scale (ESS) was used to measure daytime drowsiness, and the Clinical Global Impression-Improvement (CGI-I) scale was used to determine clinical improvement. Pre- and post-treatment data were analyzed in IBM SPSS Statistics for Windows, Version 26.0 (Released 2019; IBM Corp., Armonk, New York, United States) using statistical techniques such as paired t-tests, ANOVA, and chi-square tests. Results Trazodone, doxepin, and melatonin were evaluated for their effectiveness and tolerability in improving sleep quality and reducing daytime drowsiness among 175 psychiatric patients (n=58 for melatonin, n=59 for trazodone, n=58 for doxepin). Trazodone showed the greatest improvement in sleep quality, with significant reductions in PSQI scores at six months (mean decrease = 7.0, SD = 1.9) and the highest CGI-I improvement rates (n=59, 76%, p = 0.02), but it was associated with frequent adverse effects, including morning grogginess (n=59, 15%, p = 0.03) and orthostatic hypotension (n=59, 10%, p = 0.02). Doxepin significantly enhanced sleep continuity (PSQI reduction = 6.8, SD = 2.1) and had a better tolerability profile than trazodone but was linked to dry mouth (n=58, 13%, p = 0.04). Melatonin, while slightly less effective in improving sleep quality (PSQI reduction = 6.1, SD = 2.0), had the fewest adverse effects, including the lowest rates of morning grogginess (n=58, 5%, p = 0.03) and dizziness (n=58, 10%, p = 0.41), and significantly reduced daytime drowsiness (ESS decrease = 3.9, SD = 1.7, p = 0.04). These findings highlight trazodone and doxepin as the most effective treatments, while melatonin offers better tolerability for patients concerned about adverse effects. Conclusion In psychiatric patients, trazodone was the most successful medication for enhancing sleep quality; however, other groups cannot use it due to its adverse effects. For patients who were more likely to have side effects, melatonin was a safer option, but doxepin offered a good balance between effectiveness and tolerability.

Postoperative use of sleep aids and delirium in older adults after major surgery: A retrospective cohort study

BACKGROUND

Sleep aids are commonly prescribed to treat sleep disturbance, a modifiable risk factor for postoperative delirium in older patients. The use of melatonin receptor agonists in the postoperative period has been increasing. The comparative safety of melatonin receptor agonists, zolpidem, and temazepam remains uncertain.

METHODS

This retrospective study included 22,083 patients ≥65 years old who initiated melatonin receptor agonists, zolpidem, or temazepam after major surgery in the Premier Healthcare Database 2009-2018. We performed propensity score-based overlap weighting and estimated the risk ratio (RR) and risk difference (RD) of postoperative delirium as the primary outcome and a composite of delirium or new antipsychotic initiation, pneumonia, and in-hospital mortality as secondary outcomes.

RESULTS

The mean age of the study population was 78 (SD, 7) years and 50% were female. There was no significant difference in the risk of postoperative delirium among patients treated with melatonin receptor agonists (3.4%, reference group), zolpidem (2.9%; RR [95% CI], 0.9 [0.7-1.2]; RD [95% CI] per 100 persons, -0.3 [-1.1 to 0.6]), and temazepam (3.1%; 0.9 [0.7-1.1]; RD [95% CI] per 100 persons, -0.5 [-1.2 to 0.3]). The risks of delirium or new antipsychotic initiation, pneumonia, and in-hospital mortality were also similar among all groups.

CONCLUSIONS

Melatonin receptor agonists were not associated with a lower risk of postoperative delirium and other adverse outcomes compared with zolpidem and temazepam in older adults after major surgery.

Comparing the effect of sedation with dexmedetomidine and propofol on sleep quality of patients after cardiac surgery: A randomized clinical trial

Introduction

Sleep quality is the main concern of patients after cardiac surgery. We compared the effect of two routinely used sedatives on the sleep quality of patients admitted to the intensive care unit (ICU) after cardiovascular surgery.

Methods

It is a prospective, controlled, randomized clinical trial. A total of 120 patients, after cardiac surgery were enrolled. During extubating, patients were randomized into two groups: 60 patients received an infusion of dexmedetomidine (precede; 0.5 μg/kg/h), and 60 patients received 50 μg/kg/min propofol for 6 hours. Baseline characteristics were compared between the groups. The patients completed the St. Mary's Hospital Sleep Questionnaire, and the scores were compared between the groups.

Results

The groups were not different in terms of demographics, underlying diseases, smoking/drug abuse/alcohol, number of vessels involved, history of non-cardiac surgery, and mean levels of serum parameters (P>0.05). Most of the medications used were similar between the groups (P>0.05), except calcium channel blockers (more frequently used in the propofol group [P=0.027). The details of surgery were not statistically significant different (P>0.05); but, the mean volume of platelet received after the surgery was higher in propofol group (P=0.03). The propofol group had less problems with last night's sleep (0 vs 0.1±0.66), felt more clear-headed (4.9±0.6 vs 4.68±0.58, were more satisfied with their last night's sleep (52.1% vs 47.9%), but spent more time getting into sleep (0.38±1.67 vs 0 ) (P<0.5).

Conclusion

The sleep quality of patients under the influence of propofol seemed to be better than dexmedetomidine after cardiac surgery.

Reprint of: An assessment of a sleep aid and sleep promotion practices in hospitalized medical patients

BACKGROUND

Half of patients admitted to medicine units report sleep disruption, which increases the risk of sleep deprivation. Non-pharmacological interventions are the first step to improving sleep. However, utilization of sleep aids continues to be prevalent. Limited data are available on sleep aid prescribing practices across transitions of care.

OBJECTIVES

The aim of this study was to describe the current practices for assessing sleep and prescribing pharmacologic agents to promote sleep in the adult medicine population.

METHODS

This study was designed as a single-center, retrospective, observational cohort study of all patients discharged by the general medicine teams over a 3-month period (September 2019- November 2019). Prior to admission, inpatient and discharge prescriptions for sleep aids were recorded, and documentation of sleep assessments and non-pharmacological interventions were evaluated.

RESULTS

Of 754 patients included, 211 (28%) were prescribed a sleep aid while inpatient. During hospitalization, 124 (16%) patients had at least one documented sleep assessment, and only 22 (3%) were ordered the institutional non-pharmacological sleep promotion order set. The most prescribed sleep aid in inpatients was melatonin (50%), as well as prior to admission (35%) and at discharge (25%). Overall, the relative reduction in sleep aid prescriptions between admission and discharge was 67%.

CONCLUSION

Inpatient sleep aid prescribing is common in medical patients. Despite this, sleep assessments and the standard of care of non-pharmacological interventions are rarely utilized. Future efforts should focus on implementation of strategies to make sleep assessments and non-pharmacological sleep promotion routine and consistent in the inpatient setting.

Night-Time Noise and Sleep Quality in an Internal Medicine Ward in Portugal: An Observational Study

INTRODUCTION

Hospitals should provide a quiet environment to promote patient healing and well-being. However, published data indicates that World Health Organization's guidelines are frequently not met. The aim of the present study was to quantify night-time noise levels in an internal medicine ward and evaluate sleep quality, as well as the use of sedative drugs.

MATERIAL AND METHODS

Prospective observational study in an acute internal medicine ward. Between April 2021 and January 2022, on random days, noise was recorded using a smartphone app (Apple® iOS, Decibel X). Night-time noise was recorded from 10 p.m. to 8 a.m. During the same period, hospitalized patients were invited to respond to a questionnaire regarding their sleep quality.

RESULTS

A total of 59 nights were recorded. The average noise level recorded was 55 dB with a minimum of 30 dB and a maximum of 97 dB. Fifty-four patients were included. An intermediate score for night-time sleep quality (35.45 out of 60) and noise perception (5.26 out of 10) was reported. The main reasons for poor sleep were related to the presence of other patients (new admission, acute decompensation, delirium, and snoring), followed by equipment, staff noise and surrounding light. Nineteen patients (35%) were previous users of sedatives, and during hospitalization 41 patients (76%) were prescribed sedatives.

CONCLUSION

The noise levels detected in the internal medicine ward were higher than the levels recommended by the World Health Organization. Most patients were prescribed sedatives during hospitalization.

The Function of Sleep and the Treatment of Primary Insomnia

BACKGROUND

Approximately 21 900 women and 35 300 men developed lung cancer in Germany in 2018, and 16 999 women and 27 882 men died of it. The outcome mainly depends on the tumor stage. In early stages (stage I or II), treatment can be curative; unfortunately, because early-stage lung cancers are generally asymptom - atic, 74% of women and 77% of men already have advanced-stage disease (stage III or IV) at the time of diagnosis. Screening with low-dose computed tomography is an option enabling early diagnosis and curative treatment.

METHODS

This review is based on pertinent articles retrieved by a selective search of the literature on screening for lung cancer.

RESULTS

In the studies of lung cancer screening that have been published to date, sensitivity ranged from 68.5% to 93.8%, and specificity from 73.4% to 99.2%. A meta-analysis by the German Federal Office for Radiation Protection revealed a 15% reduction in lung cancer mortality when low-dose computed tomography was used in persons who were judged to be at high risk for lung cancer (risk ratio [RR] 0.85, 95% confidence interval [0.77; 0.95]). 1.9% of subjects died in the screening arm of the meta-analysis, and 2.2% in the control group. The observation periods ranged from 6.6 to 10 years; false-positive rates ranged from 84.9% to 96.4%. Malignant findings were confirmed in 45% to 70% of the biopsies or resective procedures that were performed.

CONCLUSION

Systematic lung cancer screening with low-dose CT lowers mortality from lung cancer in (current or former) heavy smokers. This benefit must be weighed against the high rate of false-positive findings and overdiagnoses.

An investigation of psychoactive polypharmacy and related gender-differences in older adults with dementia: a retrospective cohort study

BACKGROUND

Older adults living with dementia may express challenging responsive behaviours. One management strategy is pharmacologic treatment though these options often have limited benefit, which may lead to multiple treatments being prescribed.

METHODS

The aim of the present study was to describe psychoactive medication polypharmacy and explore factors associated with psychoactive polypharmacy in a cohort of older adults living with dementia in Nova Scotia, Canada, including a gender-stratified analysis. This was a retrospective cohort study of those aged 65 years or older with a recorded diagnosis of dementia between 2005 and 2015. Medication dispensation data was collected from April 1, 2010, or dementia diagnosis (cohort entry) to either death or March 31, 2015 (cohort exit). Psychoactive medication claims were captured. Psychoactive medication polypharmacy was defined as presence of three or more psychoactive prescription medications dispensed to one subject and overlapping for more than 30 days. Psychoactive polypharmacy episodes were described in duration, quantity, and implicated medications. Regression analysis examined factors associated with experience and frequency of psychoactive polypharmacy. All analysis were stratified by gender.

RESULTS

The cohort included 15,819 adults living with dementia (mean age 80.7 years; 70.0% female), with 99.4% (n = 15,728) receiving at least one psychoactive medication over the period of follow-up. Psychoactive polypharmacy was present in 19.3% of the cohort. The gender specific logistic regressions demonstrated that for both men and women a younger age was associated with an increased risk of psychoactive polypharmacy (women: OR 0.97, 95%CI[0.96, 0.98], men: OR 0.96, 95%CI[0.95, 0.97]). Men were less likely to experience psychoactive polypharmacy if their location of residence was urban (OR 0.86, 95%CI[0.74, 0.99]). There was no significant association between location of residence (urban or rural) and psychoactive polypharmacy for women living with dementia. Antidepressants were the most dispensed medication class, while quetiapine was the most dispensed medication.

CONCLUSIONS

This study suggests that of adults living with dementia those of younger ages were more likely to experience psychoactive polypharmacy and that men living with dementia in rural locations may benefit from increased access to non-pharmacological options for dementia management.

Melatonin for Insomnia in Medical Inpatients: A Narrative Review

In this narrative review, we describe what is known about non-pharmacological and pharmacological treatments for insomnia in medical inpatients, with a focus on melatonin. Hospital-acquired insomnia is common, resulting in shortened total sleep time and more nighttime awakenings. Sleep disturbance has been shown to increase systemic inflammation, pain, and the likelihood of developing delirium in hospital. Treatment for insomnia includes both non-pharmacological and pharmacological interventions, the latter of which requires careful consideration of risks and benefits given the known adverse effects. Though benzodiazepines and non-benzodiazepine benzodiazepine receptor agonists are commonly prescribed (i.e., sedative-hypnotics), they are relatively contraindicated for patients over the age of 65 due to the risk of increased falls, cognitive decline, and potential for withdrawal symptoms after long-term use. Exogenous melatonin has a comparatively low likelihood of adverse effects and drug-drug interactions and is at least as effective as other sedative-hypnotics. Though more research is needed on both its effectiveness and relative safety for inpatients, small doses of melatonin before bedtime may be an appropriate choice for inpatients when insomnia persists despite non-pharmacological interventions.

Prescribing decision making by medical residents on night shifts: A qualitative study

INTRODUCTION

Prescribing of medications with well-known adverse effects, like antipsychotics or benzodiazepines, during hospitalisation is extremely common despite guideline recommendations against their use. Barriers to optimal prescribing, including perceived pressure from allied health professionals and fatigue, may be particularly pronounced for less experienced medical residents, especially during night shifts when these medications are often prescribed. Under these circumstances, physicians may be more likely to use 'quick', often referred to as System 1 choices, rather than 'considered' System 2 strategies for decisions. Understanding how medical residents use, these different cognitive approaches could help develop interventions to improve prescribing.

METHODS

To understand decision-making and contextual contributors that influence suboptimal prescribing during night coverage by medical residents, we conducted semi-structured qualitative interviews with residents in general medicine inpatient settings. The interviews elicited perspectives on shift routines, stressful situations, factors influencing prescribing decision making and hypothetical measures that could improve prescribing. Interviews were audio-recorded and transcribed. Data were analysed using codes developed by the team to generate themes using immersion/crystallisation approaches.

RESULTS

We conducted interviews with 21 medical residents; 47% were female, 43% were White, and 43% were Asian. We identified five key themes: (i) time pressures affecting prescribing decisions, (ii) fears of judgement by senior physicians and peers and being responsible for patient outcomes, (iii) perceived pressure from nursing staff, amplified by nurses' greater experience, (iv) clinical acuity as a key factor influencing prescribing, and (v) strategies to improve communication between members of the care team, like ensuring adequate hand-off by day teams.

CONCLUSION

Medical residents highlighted numerous contextual factors that promote quick thinking rather than slower thinking when prescribing on night shifts, particularly time constraints, perceived pressure and patient clinical acuity. Interventions aimed at reducing prescribing should address how to manage stress and perceived pressure in decision making.
