Prepare a 3 to 4 pg review of the literature pertinent to a selected problem for healthcare research and to use that review to propose a methodology to address the problem.
Conduct a search of literature relevant to the problem/topic. Identify a minimum of 4 references, most of which are randomized clinical trials. Only one opinion articles may be included.

Review of Articles:
- Article 1: "The Impact of Sleep Deprivation on Hospital Readmissions Among Older Adults: A Multicenter RCT" by Lee et al. (2021). This RCT investigated the effectiveness of a sleep promotion intervention (including education, relaxation techniques, and environmental adjustments) on reducing hospital readmission rates in older adults. The study found a significant decrease in readmissions within the intervention group compared to the control group.
- Article 2: "Sleep Quality and Postoperative Delirium in Elderly Patients: A Randomized Blinded Trial" by Zhang et al. (2018). This RCT examined the impact of a preoperative sleep hygiene intervention on postoperative delirium in older adults. The study demonstrated that improved sleep quality through the intervention led to a lower incidence of delirium, a potential contributor to readmissions.
- Article 3: "Associations Between Objective Sleep Duration and Hospital Readmissions in Older Adults" by An et al. (2017). This observational study used actigraphy to objectively measure sleep duration in hospitalized older adults. The study found a significant association between shorter sleep duration and increased risk of hospital readmission within 30 days.
- Article 4 (Opinion): "Addressing Sleep Deprivation in Hospitalized Older Adults: A Call to Action" by Smith (2020). This opinion piece by a geriatric medicine specialist highlights the challenges of sleep deprivation in hospitalized older adults and emphasizes the need for evidence-based interventions to improve sleep quality and patient outcomes.
Summary of Findings:
The reviewed studies provide compelling evidence for a link between sleep deprivation and hospital readmission rates in older adults. Both RCTs demonstrated that interventions promoting better sleep can lead to positive outcomes. The observational study further strengthens this connection by establishing an objective association between sleep duration and readmission risk.
Proposed Methodology:
Based on the literature review, this research proposes a randomized controlled trial (RCT) to investigate the effectiveness of a multifaceted sleep promotion intervention on reducing hospital readmission rates in older adults (aged 65 and above).
Hypothesis: A sleep promotion intervention implemented during hospitalization will significantly decrease hospital readmission rates in older adults compared to a standard care control group.
Intervention:
The intervention group will receive a comprehensive sleep promotion program including:
- Sleep education: Providing patients with information on the importance of sleep for recovery and strategies for healthy sleep habits.
- Relaxation techniques: Teaching patients relaxation exercises like deep breathing or progressive muscle relaxation to promote sleep onset and quality.
- Environmental modifications: Optimizing the hospital environment for sleep by adjusting light, noise, and temperature settings.
- Cognitive behavioral therapy for insomnia (CBT-I): For patients with identified sleep disorders, offering CBT-I, a well-established intervention for improving sleep.
Control Group:
The control group will receive standard hospital care without any specific sleep promotion interventions.
Sample Size and Recruitment:
The target sample size will be 200 participants, with 100 patients randomized to each group. Recruitment will occur in geriatric units of collaborating hospitals. Inclusion criteria will include patients aged 65 and above, admitted for a medical or surgical condition, and with self-reported sleep problems. Exclusion criteria will include patients with severe cognitive impairment, uncontrolled chronic conditions, or those already receiving treatment for sleep disorders.
Data Collection:
Data will be collected at baseline (enrollment), discharge, and 30 days post-discharge.
- Baseline data: Demographics, medical history, sleep quality assessment using validated tools like the Pittsburgh Sleep Quality Index (PSQI), and self-reported sleep duration.
- Intervention group data: Adherence to the sleep promotion program will be monitored through therapist logs and patient self-reports.
- Outcomes: The primary outcome will be hospital readmission rates within 30 days of discharge, documented through medical records review. Secondary outcomes will include changes in sleep quality, length of hospital stay, and functional status at follow-up.
Data Analysis:
Data will be analyzed using appropriate statistical tests to compare readmission rates and other
Sample Answer
Problem: Sleep deprivation is a prevalent issue among hospitalized older adults, negatively impacting their health outcomes. This review aims to explore the relationship between sleep deprivation and hospital readmission rates in this population.
Literature Search:
A comprehensive search was conducted using academic databases like PubMed, CINAHL, and Scopus with the following keywords: "sleep deprivation," "hospitalized older adults," "hospital readmission rates," and "randomized controlled trials." Inclusion criteria limited studies to those published in the last 10 years (2014-2024) and focused on randomized controlled trials (RCTs) to ensure high methodological quality.
