Low Volume Colon Prep: Your 2024 Guide

Advancements in gastroenterology have led to the development of low volume colon prep solutions, such as those often recommended by the American Society for Gastrointestinal Endoscopy, to enhance patient comfort. These modern preparations significantly reduce the amount of liquid a patient must consume compared to traditional methods, typically employing formulations involving polyethylene glycol (PEG) or sodium picosulfate. Effective low volume colon prep is crucial for a successful colonoscopy, enabling doctors to thoroughly examine the colon for polyps and other abnormalities; the OLYMPUS endoscope, a high-resolution imaging tool, requires a clean colon for optimal visibility. This 2024 guide will provide you with a clear understanding of how to navigate the process and ensure the best possible outcome.

The Unseen Foundation: Why Optimized Bowel Prep is Key to Effective Colonoscopies

Effective bowel preparation is paramount to the success of colonoscopies. It's the often-overlooked foundation upon which accurate diagnoses and, ultimately, the effectiveness of colorectal cancer screening rests.

Without a thorough cleanse, the colon's lining can be obscured by residual stool, hindering the endoscopist's ability to visualize polyps, lesions, and other abnormalities.

The Direct Link: Prep Quality and Polyp Detection

The quality of bowel preparation has a direct and measurable impact on polyp detection rates. Studies consistently demonstrate that inadequate bowel cleansing leads to missed polyps. This is especially concerning for smaller, but potentially precancerous, adenomas.

A poorly prepped colon can effectively hide these crucial indicators, diminishing the efficacy of the entire screening process. Essentially, a suboptimal prep negates the benefits of undergoing a colonoscopy in the first place. This directly impacts the effectiveness of colorectal cancer screening, potentially delaying diagnosis and treatment.

Low-Volume Preps: A Patient-Centric Shift

Traditional colonoscopy preparations often involve consuming a large volume of liquid, which can be unpleasant and difficult for many patients.

This challenge has led to the development and increasing adoption of low-volume colon preparation solutions. These alternatives aim to improve the patient experience without compromising the effectiveness of the cleanse.

Enhanced Adherence, Improved Tolerability

The primary advantage of low-volume preps lies in their enhanced patient adherence and tolerability.

By reducing the volume of liquid required, these solutions make the preparation process more manageable and less burdensome for individuals. This increased tolerability translates directly into better adherence to the prescribed regimen.

When patients can comfortably complete the prep, the likelihood of achieving a clean colon significantly increases. Ultimately, this improves the accuracy and effectiveness of the colonoscopy itself.

The shift towards low-volume preparations represents a crucial step in making colorectal cancer screening more accessible and patient-friendly, while simultaneously improving the quality of the examination.

Deciphering Low-Volume Colon Preparation Medications: A Comprehensive Guide

The success of a colonoscopy hinges significantly on the quality of the bowel preparation. This, in turn, relies heavily on the choice and proper administration of the preparation medication. Fortunately, low-volume options have emerged as a more palatable and tolerable alternative to traditional high-volume regimens. Let's delve into the specifics of these low-volume preparations.

OSPHO Tablets (Oral Sodium Phosphate)

OSPHO tablets, containing oral sodium phosphate, were previously a commonly used bowel preparation. However, due to significant safety concerns, their use has become less frequent.

Mechanism of Action

Sodium phosphate acts as an osmotic laxative, drawing fluid into the bowel and promoting evacuation.

Usage Guidelines

OSPHO tablets were traditionally administered in a split-dose regimen.

Benefits

• Effective bowel cleansing.

Potential Side Effects and Risks

OSPHO tablets carry a significant risk of electrolyte imbalances, particularly hyperphosphatemia, which can lead to serious complications such as kidney damage and cardiac arrhythmias.

Contraindications

OSPHO tablets are contraindicated in patients with kidney disease, heart failure, bowel obstruction, or electrolyte abnormalities. Due to the serious risk of complications, alternative bowel preparation methods are generally preferred.

Choosing the Right Preparation

Selecting the most appropriate low-volume colon preparation requires careful consideration of the patient's medical history, preferences, and potential risks. A thorough discussion with the healthcare provider is essential to ensure the chosen preparation is both effective and safe.

Adjunctive Medications: Enhancing Patient Comfort and Prep Effectiveness

The success of a colonoscopy hinges significantly on the quality of the bowel preparation. This, in turn, relies heavily on the choice and proper administration of the preparation medication. Fortunately, low-volume options have emerged as a more palatable and tolerable alternative. However, even with these advancements, certain adjunctive medications can play a crucial role in further enhancing both patient comfort and the overall effectiveness of the bowel preparation process. These medications are not meant to replace the primary prep solution, but rather to complement it.

Understanding the Role of Adjunctive Medications

Adjunctive medications are those taken alongside the main colonoscopy preparation to address specific needs and potential side effects. They can help to alleviate discomfort, reduce bloating, and prevent nausea, ultimately improving patient compliance and the thoroughness of the cleansing process. This holistic approach to bowel preparation acknowledges that patient experience is integral to achieving optimal results.

Specific Adjunctive Medications and Their Uses

Several adjunctive medications are commonly used to improve the bowel preparation experience. It is important to consult with a healthcare provider to determine the appropriate medications and dosages for individual needs.

By addressing common side effects and individual needs, these medications can help to improve the overall experience and ensure a thorough and effective cleansing process, ultimately contributing to better colorectal cancer screening outcomes.

The Patient's Journey: Maximizing Adherence, Comfort, and Understanding

The success of a colonoscopy hinges significantly on the quality of the bowel preparation. This, in turn, relies heavily on the choice and proper administration of the preparation medication. Fortunately, low-volume options have emerged as a more palatable and tolerable alternative, but their effectiveness still depends on the patient's active participation and understanding of the process. Optimizing the patient's journey through the bowel preparation process is key to a successful and comfortable colonoscopy.

Navigating the Clear Liquid Diet: A Crucial First Step

The cornerstone of any effective bowel preparation is adherence to a clear liquid diet in the days leading up to the procedure. This dietary restriction is designed to clear the digestive system of solid waste, ensuring optimal visualization during the colonoscopy.

Decoding Clear Liquids: What's Allowed and What's Not

Understanding what constitutes a "clear liquid" is paramount. Acceptable options generally include:

• Broth (clear, without solids)
• Clear juices (apple, white grape, white cranberry)
• Gelatin (such as Jell-O, without added fruit or toppings)
• Water
• Plain coffee or tea (without milk or cream)
• Clear sports drinks (like Gatorade or Powerade)
• Clear soda (Sprite, 7-Up, or ginger ale)
• Popsicles (without fruit pieces or cream filling)

It's equally important to know what to avoid. This typically includes:

• Solid foods of any kind
• Milk or dairy products
• Juices with pulp (orange, grapefruit)
• Red or purple liquids (they can mimic blood during the procedure)
• Alcoholic beverages

Carefully reading labels is essential, and when in doubt, consulting with your healthcare provider is always the best course of action.

Timing is Everything: Start When Instructed

The timing of the clear liquid diet is just as important as the diet itself. Instructions regarding when to begin the diet must be followed precisely.

Starting too late may not allow sufficient time for the bowel to clear adequately, potentially leading to a suboptimal preparation and the need for a repeat colonoscopy.

Starting too early, while less common, can lead to unnecessary hunger and discomfort. The recommended start time is carefully calculated based on the type of preparation being used and the individual's medical history.

Enhancing Adherence: A Collaborative Approach

Bowel preparation can be challenging, but strategies to improve adherence can make the process more manageable.

Shared Decision-Making: Empowering the Patient

When possible, patients should be actively involved in choosing their bowel preparation option. Discussing the pros and cons of different preparations with your doctor, considering your individual preferences, and understanding your own medical history can significantly improve compliance.

A shared decision-making approach empowers patients and fosters a sense of ownership in the process.

Personalizing the Prep: Tailoring to Individual Needs

Factors like taste preferences, tolerance to large volumes of liquids, and existing medical conditions should all be taken into account when selecting a bowel preparation.

For example, individuals prone to nausea may benefit from a low-volume preparation, while those with difficulty tolerating certain tastes may prefer a flavored option.

Managing Side Effects: Prioritizing Comfort

Common side effects of bowel preparation include bloating, nausea, abdominal cramping, and vomiting. Addressing these side effects proactively can enhance comfort and improve the overall experience.

Practical Tips for Relief: Simple Solutions

• For bloating and cramping: Gentle abdominal massage, light exercise (walking), and avoiding gas-producing foods (even within the clear liquid diet) can provide relief.

• For nausea: Sipping on clear ginger ale, sucking on hard candies, or using anti-nausea medication (as prescribed by your doctor) can help alleviate symptoms.

• For vomiting: Taking small, frequent sips of clear liquids and avoiding large volumes at once can reduce the risk of vomiting. If vomiting persists, contact your healthcare provider.

Medication Options: When to Seek Assistance

In some cases, medication may be necessary to manage side effects. Anti-nausea medications, such as ondansetron or metoclopramide, can be prescribed by your doctor to prevent or treat nausea and vomiting.

It's crucial to discuss any concerns about side effects with your healthcare provider before starting the preparation.

Hydration is Key: Maintaining Fluid Balance

Adequate hydration is essential during bowel preparation to prevent dehydration and electrolyte imbalances.

• Aim to drink clear liquids consistently throughout the day, even when not actively consuming the bowel preparation solution.

• Pay attention to signs of dehydration, such as dizziness, lightheadedness, and decreased urination.

• If you experience symptoms of dehydration, contact your healthcare provider immediately.

Choosing clear liquids that contain electrolytes, such as sports drinks, can help replenish those lost during the bowel cleansing process.

Healthcare Professionals: Guiding Patients Through the Bowel Preparation Maze

The success of a colonoscopy hinges significantly on the quality of the bowel preparation. This, in turn, relies heavily on the choice and proper administration of the preparation medication. Fortunately, low-volume options have emerged as a more palatable and tolerable alternative, but their effective use still depends heavily on the coordinated efforts of a multidisciplinary healthcare team. Let's explore the crucial roles each member plays in ensuring a successful and comfortable colonoscopy experience for the patient.

The Gastroenterologist: Orchestrating the Colonoscopy

The gastroenterologist (GI) stands as the principal orchestrator of the colonoscopy procedure. Their responsibilities extend far beyond simply performing the examination.

First and foremost, the GI is responsible for assessing the patient's overall health and medical history to determine the most appropriate bowel preparation regimen. This involves considering factors like age, comorbidities (such as kidney or heart disease), current medications, and previous experiences with bowel preparation.

Based on this assessment, the GI prescribes the specific low-volume preparation, providing clear and concise instructions on how to properly administer it. They must also educate the patient on the importance of adhering to the dietary restrictions and fluid intake guidelines.

During the colonoscopy, the GI meticulously examines the colon for any abnormalities, such as polyps or tumors. The quality of the bowel preparation directly impacts their ability to visualize the colon lining and accurately detect these potentially cancerous lesions.

Finally, the GI interprets the findings of the colonoscopy and develops an appropriate management plan, which may include polyp removal, further testing, or surveillance colonoscopies.

The Primary Care Physician: The Screening Champion

The primary care physician (PCP) plays a vital role in promoting colorectal cancer screening and referring patients for colonoscopies.

They are often the first point of contact for patients seeking information about colorectal cancer prevention. PCPs are responsible for educating patients about the benefits of screening, discussing the various screening options available (including colonoscopy, stool-based tests, and flexible sigmoidoscopy), and addressing any concerns or anxieties they may have.

When colonoscopy is deemed the most appropriate screening method, the PCP initiates the referral process, ensuring that the patient has access to a qualified gastroenterologist.

They may also play a role in reinforcing the importance of proper bowel preparation and encouraging patients to adhere to the prescribed regimen.

The Endoscopy Nurse: Providing Education and Support

Endoscopy nurses are integral to the colonoscopy process, providing direct patient care and support throughout the procedure.

Prior to the colonoscopy, the endoscopy nurse reviews the bowel preparation instructions with the patient, ensuring they fully understand the steps involved and addressing any questions or concerns. They may also provide written materials and contact information for further assistance.

During the procedure, the nurse monitors the patient's vital signs, provides comfort and reassurance, and assists the gastroenterologist as needed.

Post-procedure, the nurse provides discharge instructions, including information on diet, activity restrictions, and potential side effects. They also answer any remaining questions and ensure the patient feels comfortable and confident before leaving.

The Pharmacist: Dispensing Expertise

Pharmacists possess a wealth of knowledge about medications, including bowel preparation agents.

They play a crucial role in dispensing the prescribed low-volume preparation, providing patients with detailed instructions on its proper use, and advising them on potential side effects and drug interactions.

Pharmacists can also help patients choose over-the-counter medications, such as anti-nausea remedies or simethicone, to alleviate any discomfort associated with the bowel preparation.

Furthermore, they serve as a valuable resource for answering patient questions and addressing any concerns about the preparation process.

Clear Communication: The Keystone of Success

Effective communication is paramount to ensuring a successful colonoscopy and a positive patient experience.

Each member of the healthcare team must communicate clearly and concisely with the patient, providing them with the information and support they need to navigate the bowel preparation process.

This includes explaining the purpose of the colonoscopy, outlining the steps involved in the preparation, addressing any concerns or anxieties, and answering all questions thoroughly.

By working together as a cohesive team, healthcare professionals can empower patients to take control of their colorectal health and achieve optimal outcomes.

Assessing Bowel Preparation Quality: Ensuring Accurate Colonoscopies

The success of a colonoscopy hinges significantly on the quality of the bowel preparation. This, in turn, relies heavily on the choice and proper administration of the preparation medication. Fortunately, low-volume options have emerged as a more palatable and tolerable alternative. Crucially, the efficacy of any preparation, regardless of volume, is ultimately judged by the clarity it provides during the procedure.

Therefore, understanding how bowel preparation quality is assessed and its implications is paramount for both clinicians and patients seeking optimal colorectal cancer screening.

Why Bowel Prep Quality Matters

A poorly prepared colon hinders the endoscopist's ability to visualize the colonic mucosa effectively.

This can lead to missed polyps, including precancerous adenomas, undermining the primary goal of the colonoscopy: early detection and prevention of colorectal cancer.

Adequate bowel preparation is directly linked to higher adenoma detection rates (ADR), a key performance indicator for colonoscopy quality. A substandard prep not only reduces the likelihood of finding polyps but also necessitates repeat colonoscopies, increasing costs and patient burden.

The Boston Bowel Preparation Scale (BBPS) and Other Assessment Tools

Several scales exist to standardize the assessment of bowel preparation quality. Among the most widely used is the Boston Bowel Preparation Scale (BBPS).

The BBPS segments the colon into three regions: the right colon, the transverse colon, and the left colon.

Each segment is then assigned a score from 0 to 3, based on the degree of cleansing:

• 0: Unprepared colon segment with mucosa not seen because of solid stool.
• 1: Portion of mucosa of the colon segment seen, but other areas not well seen because of stool, residue, and/or opaque fluid.
• 2: Minor amount of stool, residue, or opaque fluid but mucosa of colon segment seen well.
• 3: Entire mucosa of colon segment seen well with no stool, residue, or opaque fluid.

The total BBPS score, ranging from 0 to 9, provides an overall assessment of bowel preparation quality.

A score of 6 or higher, with each segment scored at least 2, is generally considered adequate for a successful colonoscopy.

Other scales, such as the Aronchick Scale and the Ottawa Bowel Preparation Scale, are also used. However, the BBPS is favored for its simplicity and reliability.

Criteria for Evaluating Prep Quality

The evaluation criteria focus on the presence and quantity of residual stool or fluid within the colon. Endoscopists assess the clarity of the view, noting any areas obscured by inadequate cleansing.

Factors considered include:

• The amount of solid stool present.
• The presence of opaque or colored fluid.
• The adherence of debris to the colonic wall.
• The ability to visualize the mucosa clearly.

The goal is to achieve a colon that is free of significant debris, allowing for complete visualization of the colonic lining and detection of even small polyps.

The Impact on Polyp Detection and Outcomes

Poor bowel preparation directly reduces polyp detection rates (PDR) and adenoma detection rates (ADR).

Studies have consistently shown that inadequate prep leads to missed lesions and the need for earlier repeat colonoscopies.

This not only increases healthcare costs but also exposes patients to unnecessary risks and anxiety.

Furthermore, missed adenomas can progress to colorectal cancer, diminishing the effectiveness of the screening program.

Optimizing bowel preparation is therefore a critical step in maximizing the benefits of colonoscopy and improving patient outcomes. It allows for more accurate detection of polyps and ultimately reduces the risk of colorectal cancer.

Special Considerations: Tailoring Prep for Specific Patient Populations

Assessing Bowel Preparation Quality: Ensuring Accurate Colonoscopies The success of a colonoscopy hinges significantly on the quality of the bowel preparation. This, in turn, relies heavily on the choice and proper administration of the preparation medication. Fortunately, low-volume options have emerged as a more palatable and tolerable alternative. However, not all patients are created equal, and certain medical conditions necessitate a carefully tailored approach to bowel preparation. This section addresses the crucial considerations for individuals with specific comorbidities that can significantly impact the safety and efficacy of the process.

The Imperative of Individualized Bowel Prep

Standard bowel preparation protocols are often insufficient or potentially harmful for patients with underlying health issues. A one-size-fits-all approach can lead to adverse events, incomplete bowel cleansing, and ultimately, a less effective colonoscopy. Tailoring the prep to the individual's medical profile is essential for maximizing both safety and diagnostic accuracy. We’ll explore key considerations for patients with kidney disease and heart failure, highlighting the adjustments needed to mitigate risks.

Kidney Disease (Chronic Kidney Disease - CKD): A Delicate Balance

Patients with chronic kidney disease (CKD) require special attention during bowel preparation due to their impaired ability to regulate fluid and electrolyte balance. Many traditional bowel preparations contain high levels of sodium, magnesium, or phosphate, which can exacerbate existing kidney dysfunction.

Choosing the Right Prep

Phosphate-based preparations, such as oral sodium phosphate (OSPHO) tablets, are generally contraindicated in patients with CKD due to the risk of phosphate nephropathy, a condition that can lead to irreversible kidney damage. Magnesium-containing preps also require caution. Low-volume PEG solutions (polyethylene glycol) are often favored.

Monitoring Hydration and Electrolytes

Careful monitoring of hydration status is vital. Overhydration can lead to fluid overload, while dehydration can worsen kidney function. Pre- and post-procedure electrolyte levels (sodium, potassium, magnesium, phosphate) should be assessed to detect and manage any imbalances promptly.

Communication is Key

Open communication between the gastroenterologist, nephrologist, and patient is crucial to select the most appropriate and safest preparation regimen. A clear understanding of the patient's kidney function and overall health status is essential.

Heart Failure (Congestive Heart Failure - CHF): Managing Fluid Overload

Patients with congestive heart failure (CHF) are particularly susceptible to fluid shifts and electrolyte imbalances induced by bowel preparation. The large volumes of fluid required for standard preps can exacerbate fluid retention, leading to pulmonary edema and worsening heart failure symptoms.

Minimizing Fluid Shifts

The key for patients with CHF is to minimize the volume of fluid intake and avoid preparations that promote significant fluid shifts. Low-volume PEG solutions are often preferred. Sodium phosphate preparations should generally be avoided due to their sodium content.

Diuretic Management

Diuretics, commonly prescribed for CHF, may need to be adjusted in the days leading up to the colonoscopy. Close monitoring of weight, blood pressure, and heart rate is essential to detect early signs of fluid overload. Patients should consult their cardiologist or primary care physician for guidance on diuretic management.

The Split-Dose Advantage: A Broadly Applicable Strategy

Regardless of the specific comorbidity, a split-dose regimen – where the preparation is divided into two doses, with the second dose taken the morning of the procedure – can significantly improve both efficacy and tolerability.

For patients with kidney disease or heart failure, splitting the dose can reduce the fluid and electrolyte burden at any one time, minimizing the risk of complications. This approach optimizes bowel cleansing while promoting better patient comfort and adherence. The split-dose regimen should be considered a cornerstone of tailored bowel preparation, particularly in patients with complex medical conditions.

Tailoring bowel preparation to the specific needs of patients with comorbidities like CKD and CHF is paramount. Careful consideration of the preparation type, meticulous monitoring of fluid and electrolyte balance, and open communication between healthcare providers and patients are essential to ensure a safe and effective colonoscopy. The split-dose approach offers a valuable strategy for optimizing both bowel cleansing and patient tolerance in these vulnerable populations. Ultimately, a personalized approach leads to better outcomes and promotes the overall health and well-being of the patient.

Navigating Guidelines: Key Organizations and Their Recommendations

Special Considerations: Tailoring Prep for Specific Patient Populations Assessing Bowel Preparation Quality: Ensuring Accurate Colonoscopies

The success of a colonoscopy hinges significantly on the quality of the bowel preparation. This, in turn, relies heavily on the choice and proper administration of the preparation medication. Fortunately, low-volume preparations offer a patient-friendly option, but understanding the best practices is important. This is where guidelines from key professional societies play a crucial role, informing clinicians and patients alike on the most effective and safe approaches.

The Role of Professional Societies

Several leading gastroenterology societies dedicate considerable resources to establishing evidence-based guidelines for colonoscopy and bowel preparation. These guidelines are not arbitrary pronouncements; they are carefully crafted documents that synthesize the best available research, clinical experience, and patient preferences.

These professional societies regularly update their recommendations. This ensures the most current, evidence-based practices are being used in clinical settings.

Addressing Potential Complications: Mitigation and Management Strategies

The success of a colonoscopy hinges significantly on the quality of the bowel preparation. This, in turn, relies heavily on the choice and protocol of the preparation itself. While generally safe, bowel preparation is not without potential complications. Understanding these risks, alongside implementing proactive mitigation strategies, is paramount for patient safety and well-being.

Recognizing and Minimizing Serious Risks

Bowel preparation, although generally well-tolerated, carries a small risk of serious complications. While rare, these complications demand immediate recognition and intervention.

Colon Perforation: Prevention and Response

Colon perforation represents one of the most concerning, albeit rare, complications. It can occur due to the mechanical effects of the procedure or, less commonly, as a result of the bowel preparation itself, especially in patients with pre-existing bowel conditions or anatomical abnormalities.

Minimizing the risk involves careful patient selection, a thorough review of medical history, and gentle procedural technique by the endoscopist. Bowel inflammation from certain preps could lead to perforation; this is why careful consideration of risk factors is crucial.

Prompt recognition of perforation is critical. Symptoms may include severe abdominal pain, fever, chills, or signs of peritonitis. Immediate surgical consultation is typically required to address the perforation and prevent further complications.

Electrolyte Imbalances and Dehydration

Certain bowel preparations, particularly those containing high concentrations of osmotic agents, can lead to significant electrolyte imbalances, such as hyponatremia (low sodium), hypokalemia (low potassium), and dehydration.

Elderly patients, individuals with kidney disease, and those taking certain medications (e.g., diuretics, ACE inhibitors) are at increased risk. Close monitoring of electrolyte levels is recommended in these patients.

Encouraging adequate fluid intake during the preparation process is essential to prevent dehydration. Consider using balanced electrolyte solutions to replace lost fluids and minimize electrolyte disturbances.

Aspiration Pneumonia

Although uncommon, aspiration pneumonia can occur if patients vomit during the bowel preparation and aspirate gastric contents into their lungs. This risk is higher in patients with impaired swallowing or altered mental status.

To mitigate this risk, advise patients to remain upright during and after taking the preparation. Anti-emetic medications can also be prescribed to prevent nausea and vomiting.

Managing Common Side Effects Effectively

Beyond the rare but serious complications, bowel preparation frequently induces a range of less severe, yet bothersome, side effects. Effective management of these common complaints can improve patient comfort and adherence to the preparation regimen.

Nausea and Vomiting

Nausea and vomiting are common complaints during bowel preparation. Several strategies can help alleviate these symptoms:

• Administering anti-emetic medications (e.g., ondansetron, metoclopramide) before and during the preparation.
• Encouraging patients to sip the preparation slowly and in small amounts.
• Advising patients to avoid strong smells or flavors that may trigger nausea.

Abdominal Bloating and Cramping

Abdominal bloating and cramping are frequently reported side effects caused by the increased fluid volume and gas production within the colon.

• Encouraging gentle ambulation or movement.
• Using simethicone to reduce gas formation.
• Applying a warm compress to the abdomen.
• In select cases, temporarily slowing down the prep to allow for more comfortable expulsion.

Anal Irritation

Frequent bowel movements can lead to anal irritation and discomfort.

• Instructing patients to use moist wipes or a gentle cleanser instead of dry toilet paper.
• Applying a barrier cream (e.g., zinc oxide) to the perianal area.
• Considering a sitz bath to soothe irritated tissues.

Sleep Disruption

The frequent need to use the bathroom during the night can disrupt sleep and cause fatigue.

• Encouraging patients to start the preparation earlier in the day.
• Recommending the use of earplugs or a sleep mask to minimize disturbances.
• Advising patients to avoid caffeine or alcohol before bedtime.
