A systematic review of non-pharmacological interventions to improve nighttime sleep among residents of long-term care settings

Background

Disturbances in sleep and circadian rhythms are common among residents of long-term care facilities. In this systematic review, we aim to identify and evaluate the literature documenting the outcomes associated with non-pharmacological interventions to improve nighttime sleep among long-term care residents.

Methods

The Preferred Reporting Items for Systematic Reviews guided searches of five databases (MEDLINE, Embase, CINAHL, Scopus, and Cochrane Library) for articles reporting results of experimental or quasi-experimental studies conducted in long-term care settings (nursing homes, assisted-living facilities, or group homes) in which nighttime sleep was subjectively or objectively measured as a primary outcome. We categorized each intervention by its intended use and how it was administered.

Results

Of the 54 included studies evaluating the effects of 25 different non-pharmacological interventions, more than half employed a randomized controlled trial design (n = 30); the others used a pre-post design with (n = 11) or without (n = 13) a comparison group. The majority of randomized controlled trials were at low risk for most types of bias, and most other studies met the standard quality criteria. The interventions were categorized as environmental interventions (n = 14), complementary health practices (n = 12), social/physical stimulation (n = 11), clinical care practices (n = 3), or mind-body practices (n = 3). Although there was no clear pattern of positive findings, three interventions had the most promising results: increased daytime light exposure, nighttime use of melatonin, and acupressure.

Conclusions

Non-pharmacological interventions have the potential to improve sleep for residents of long-term care facilities. Further research is needed to better standardize such interventions and provide clear implementation guidelines using cost-effective practices.

An Integrative Review of Nonpharmacological Interventions to Improve Sleep among Adults with Advanced Serious Illness

BACKGROUND

Sleep fragmentation is common among those with advanced serious illness. Nonpharmacological interventions to improve sleep have few, if any, adverse effects and are often underutilized in these settings.

OBJECTIVE

We aimed to summarize the literature related to nonpharmacological interventions to improve sleep among adults with advanced serious illness.

METHODS

We systematically searched six electronic databases for literature reporting sleep outcomes associated with nonpharmacological interventions that included participants with advanced serious illness during the period of 1996-2016.

RESULTS

From a total of 2731 results, 42 studies met the inclusion criteria. A total of 31 individual interventions were identified, each evaluated individually and some in combination with other interventions. Twelve of these studies employed either multiple interventions within an intervention category (n = 8) or a multicomponent intervention consisting of interventions from two or more categories (n = 5). The following intervention categories emerged: sleep hygiene (1), environmental (6), physical activity (4), complementary health practices (11), and mind-body practices (13). Of the 42 studies, 22 demonstrated a statistically significant, positive impact on sleep and represented each of the categories. The quality of the studies varied considerably, with 17 studies classified as strong, 17 as moderate, and 8 as weak.

CONCLUSIONS

Several interventions have been demonstrated to improve sleep in these patients. However, the small number of studies and wide variation of individual interventions within each category limit the generalizability of findings. Further studies are needed to assess interventions and determine effectiveness and acceptability.

Environmental Design for End-of-Life Care: An Integrative Review on Improving the Quality of Life and Managing Symptoms for Patients in Institutional Settings

CONTEXT

The environment in which end-of-life (EOL) care is delivered can support or detract from the physical, psychological, social, and spiritual needs of patients, their families, and their caretakers.

OBJECTIVES

This review aims to organize and analyze the existing evidence related to environmental design factors that improve the quality of life and total well-being of people involved in EOL care and to clarify directions for future research.

METHODS

This integrated literature review synthesized and summarized research evidence from the fields of medicine, environmental psychology, nursing, palliative care, architecture, interior design, and evidence-based design.

RESULTS

This synthesis analyzed 225 documents, including nine systematic literature reviews, 40 integrative reviews, three randomized controlled trials, 118 empirical research studies, and 55 anecdotal evidence. Of the documents, 192 were peer-reviewed, whereas 33 were not. The key environmental factors shown to affect EOL care were those that improved 1) social interaction, 2) positive distractions, 3) privacy, 4) personalization and creation of a home-like environment, and 5) the ambient environment. Possible design interventions relating to these topics are discussed. Examples include improvement of visibility and line of sight, view of nature, hidden medical equipment, and optimization of light and temperature.

CONCLUSION

Studies indicate several critical components of the physical environment that can reduce total suffering and improve quality of life for EOL patients, their families, and their caregivers. These factors should be considered when making design decisions for care facilities to improve physical, psychological, social, and spiritual needs at EOL.

The relationship between neutrophil/lymphocyte ratio and the TIMI flow grade in patients with STEMI undergoing primary PCI

OBJECTIVES

ST segment elevation myocardial infarction (STEMI) is an important cause of the morbidity and mortality in coronary artery disease. The aim of this study is to investigate the relationship between hematologic parameters and post primary PCI coronary no-reflow.

PATIENTS AND METHODS

A total of 145 consecutive STEMI patients (mean age=58.2±12.3 years) and healthy volunteer admitted within 6 hours from symptom onset were enrolled to the study in the cardiology clinics. The STEMI patients were divided into 2 groups based on the Thrombolysis In Myocardial Infarction (TIMI) flow grade. No-reflow was defined as post-PCI TIMI Flow Grade 0, 1 or 2 and angiographic success was defined as TIMI Grade 3 Flow.

RESULTS

Diabetes mellitus hypertension and smoking status were similar between groups. With respect to baseline laboratory status, fasting glucose, blood urea nitrogen, creatinine levels were not significantly different between groups. The neutrophil/lymphocyte (N/L) ratio was also significantly higher in STEMI group (7.1±4.6 vs. 2.3±1.7, p < 0.001). Additionally, N/L ratio was also significantly higher in No-reflow group (TIMI Flow Grade 0, 1 or 2) group (13.1±4.5 vs. 5.3±2.7, p < 0.001).

CONCLUSIONS

The N/L ratio, which is cheaply and easily measurable laboratory data is independently associated with post primary PCI coronary no-reflow.
