When CPAP Therapy Fails Alternative Treatment Options for Sleep Apnea

Understanding Why CPAP Therapy Sometimes Falls Short

For countless individuals across Southern California, CPAP therapy represents hope after a sleep apnea diagnosis. Yet within the first year, nearly 50% of patients abandon their treatment entirely. This isn’t a story of patient failure – it’s a complex interplay of physical challenges, lifestyle conflicts, and individual circumstances that make this gold-standard treatment surprisingly difficult to sustain.

The reality is that CPAP therapy, while medically effective, demands significant lifestyle adjustments that many patients find overwhelming. Understanding why these treatments fail creates opportunities for exploring alternative approaches that better match individual needs and circumstances.

Common Reasons for CPAP Non-Compliance

Mask discomfort tops the list of patient complaints, with studies showing that 60% of users report persistent issues with fit and seal. Even minor air leaks can disrupt sleep quality, creating a frustrating cycle where patients sleep poorly despite using their device. Many users describe feeling claustrophobic, particularly those who sleep on their side or stomach.

Noise sensitivity becomes another significant barrier. While modern CPAP machines operate more quietly than earlier models, the constant airflow sound disturbs both patients and their bed partners. This creates household tension that often leads to treatment discontinuation.

Travel complications frequently derail consistent use. Business travelers and vacation enthusiasts find the equipment cumbersome, especially when flying or staying in hotels. The need for distilled water, power sources, and carrying cases makes spontaneous trips challenging.

Physical Side Effects That Lead to Treatment Abandonment

Dry mouth and nasal irritation affect approximately 40% of CPAP users within the first three months. Despite humidification systems, many patients experience persistent discomfort that worsens over time. This is particularly problematic in San Diego’s dry climate, where humidity levels can drop significantly during certain seasons.

Pressure sores and skin irritation develop from prolonged mask contact. Red marks, bruising, and even open wounds can occur, especially around the bridge of the nose. These physical symptoms often worsen with time rather than improve, contrary to patient expectations.

Bloating and aerophagia (swallowing air) create digestive discomfort that extends beyond sleep hours. Patients report feeling gassy, experiencing stomach pain, and dealing with frequent belching throughout the day. This side effect particularly affects those requiring higher pressure settings.

Some users develop chronic sinusitis or ear infections due to the pressurized air system. The constant airflow can disrupt natural sinus drainage patterns, leading to recurring medical issues that require additional treatment.

Lifestyle Factors That Make CPAP Challenging

Bedroom dynamics significantly impact treatment success. Partners often complain about the equipment noise, mask appearance, or reduced intimacy. These relationship strains create emotional pressure that makes long-term compliance difficult to maintain.

Work schedules that involve shift work or irregular hours complicate consistent CPAP use. Healthcare workers, first responders, and hospitality professionals find it challenging to maintain regular sleep schedules, making effective treatment optimization nearly impossible.

Active lifestyles present unique challenges. Camping enthusiasts, frequent movers, or those with limited living space struggle with the equipment requirements. The need for consistent power sources and storage space conflicts with mobile lifestyles.

Social anxiety around the equipment affects younger patients particularly. College students and young professionals often avoid overnight stays or feel self-conscious about their appearance while wearing the mask, leading to inconsistent use patterns.

When Medical Conditions Interfere with CPAP Success

Nasal congestion from allergies or structural issues prevents effective mask seal and comfort. Patients with deviated septums, chronic rhinitis, or seasonal allergies find CPAP therapy particularly challenging. San Diego’s varied pollen seasons can exacerbate these issues throughout the year.

Gastroesophageal reflux disease (GERD) symptoms often worsen with CPAP pressure, creating a competing medical priority. The pressurized air can push stomach contents upward, intensifying heartburn and acid reflux symptoms during sleep.

Anxiety and panic disorders can be triggered by the sensation of forced air and mask confinement. These patients may require specialized personalized care approaches that address both sleep apnea and psychological comfort.

Patients exploring alternatives often benefit from comprehensive support systems that acknowledge these challenges while identifying suitable treatment modifications or alternatives that better match their individual circumstances and lifestyle requirements.

Oral Appliance Therapy: A First-Line Alternative

How Mandibular Advancement Devices Work

Mandibular advancement devices (MADs) represent the most widely prescribed type of oral appliance for sleep apnea treatment. These custom-fitted devices work by gently repositioning the lower jaw forward during sleep, which increases the diameter of the upper airway and reduces the likelihood of collapse.

The mechanism is straightforward yet effective: by advancing the mandible approximately 6-10 millimeters forward, MADs pull the tongue and surrounding soft tissues away from the back of the throat. This repositioning creates more space for airflow and significantly reduces the partial or complete blockages that characterize obstructive sleep apnea episodes.

Modern MADs feature adjustable mechanisms that allow healthcare providers to fine-tune the degree of jaw advancement. This customization proves crucial because each patient’s optimal position varies based on their specific anatomy and severity of sleep apnea. Clinical studies demonstrate that properly fitted MADs can reduce apnea-hypopnea index scores by 50-80% in appropriately selected patients.

The effectiveness of these devices stems from their ability to maintain stable airway positioning throughout different sleep stages. Unlike CPAP machines that require continuous power and can be disrupted by mask leaks, MADs provide consistent mechanical support regardless of sleep position changes or mouth breathing patterns.

Tongue Retaining Devices for Specific Sleep Apnea Types

Tongue retaining devices (TRDs) offer a specialized approach for patients whose sleep apnea primarily results from tongue-based airway obstruction. These devices use gentle suction to hold the tongue in a forward position, preventing it from falling back and blocking the airway during sleep.

TRDs prove particularly effective for patients with large tongues relative to their mouth size, a condition known as macroglossia. They also benefit individuals with poor jaw structure who cannot tolerate the forward positioning required by mandibular advancement devices. The suction mechanism creates approximately 15-20 mmHg of negative pressure, enough to maintain tongue position without causing discomfort.

Research indicates that TRDs achieve success rates of 60-70% in carefully selected patients, with effectiveness varying based on the primary site of airway collapse. Sleep studies help identify whether tongue positioning contributes significantly to a patient’s obstructive events, guiding appropriate device selection.

One advantage of TRDs is their independence from jaw positioning, making them suitable for patients with temporomandibular joint disorders or limited jaw mobility. However, they require an adaptation period as patients adjust to the sensation of tongue suction during sleep.

Custom vs. Over-the-Counter Oral Appliances

The distinction between custom-fabricated and over-the-counter oral appliances significantly impacts treatment outcomes and patient comfort. Custom devices, created from dental impressions and fitted by qualified professionals, offer superior retention, comfort, and therapeutic effectiveness compared to generic alternatives.

Custom appliances provide precise fit and controlled jaw positioning based on individual anatomy and sleep study results. The fabrication process involves detailed measurements and often includes follow-up adjustments to optimize therapeutic benefit. These devices typically last 3-5 years with proper maintenance and demonstrate success rates of 70-90% in appropriate candidates.

Over-the-counter options, while more affordable and immediately accessible, present significant limitations. Their one-size-fits-most design often results in poor retention, inadequate jaw advancement, and increased likelihood of side effects such as tooth movement or jaw discomfort. Studies show considerably lower success rates (30-50%) for generic devices compared to custom alternatives.

The investment in custom devices proves worthwhile for most patients, as proper fit directly correlates with treatment compliance and long-term success. Professional oversight also ensures appropriate monitoring for potential side effects and necessary adjustments.

Success Rates and Patient Selection Criteria

Oral appliance therapy achieves optimal results when patients meet specific selection criteria established through extensive clinical research. Success rates vary from 65-85% depending on patient characteristics, device type, and severity of sleep apnea.

Ideal candidates typically present with mild to moderate sleep apnea (AHI 5-30 events per hour), maintain healthy dentition with adequate tooth retention, and demonstrate primary airway collapse at the tongue base or soft palate level. Patients with severe sleep apnea may still benefit, particularly when CPAP therapy has failed or proves intolerable.

Body mass index plays a crucial role in treatment success, with patients having BMI under 30 showing significantly higher response rates. However, recent studies indicate that motivated patients with higher BMIs can still achieve meaningful improvements with proper device selection and ongoing monitoring.

Age factors also influence outcomes, with younger patients generally responding more favorably to oral appliance therapy. The comprehensive services approach includes thorough evaluation of these criteria to optimize treatment selection and maximize therapeutic success for each individual patient.

Surgical Treatment Options for Sleep Apnea

Upper Airway Surgery: UPPP and Modern Variations

Uvulopalatopharyngoplasty (UPPP) remains one of the most established surgical interventions for sleep apnea when CPAP therapy proves ineffective. This procedure involves removing excess tissue from the throat, including parts of the uvula, soft palate, and sometimes the tonsils, to widen the airway and reduce obstruction during sleep.

Modern variations of UPPP have evolved significantly from the traditional approach. Laser-assisted uvulopalatoplasty (LAUP) offers more precision with reduced bleeding and faster healing times. Radio frequency ablation techniques allow surgeons to shrink tissue rather than remove it entirely, resulting in less post-operative pain and complications.

Success rates for UPPP vary considerably, with studies showing 40-60% effectiveness in reducing sleep apnea severity. The procedure works best for patients with specific anatomical features, including enlarged tonsils, a long uvula, or excessive soft palate tissue. However, candidates must understand that surgical outcomes can diminish over time as tissues may gradually return to their original configuration.

Recovery from UPPP typically requires 2-3 weeks of restricted activity, with patients experiencing throat pain, difficulty swallowing, and temporary voice changes. Many San Diego area patients find that proper ongoing care during recovery significantly improves their surgical outcomes and comfort levels.

Hypoglossal Nerve Stimulation Therapy

Hypoglossal nerve stimulation represents a groundbreaking advancement in sleep apnea treatment, offering hope for patients who cannot tolerate CPAP therapy. This FDA-approved system, commonly known by the brand name Inspire, involves implanting a small device that stimulates the nerve controlling tongue movement during sleep.

The implanted device monitors breathing patterns and delivers gentle electrical pulses to the hypoglossal nerve when it detects the onset of an apneic event. This stimulation causes the tongue to move forward slightly, preventing it from blocking the airway. Patients control the device with a simple remote, turning it on before sleep and off upon waking.

Clinical trials demonstrate impressive results, with 68% of patients experiencing at least a 50% reduction in sleep apnea events. The therapy proves particularly effective for patients with moderate to severe obstructive sleep apnea who have struggled with traditional treatments. Qualification requires specific anatomical criteria, including a body mass index under 32 and the absence of complete concentric collapse at the soft palate level.

The implantation procedure typically takes 2-3 hours under general anesthesia, with most patients returning home the same day. Initial device activation occurs about one month post-surgery, followed by a series of adjustment appointments to optimize therapy settings for maximum effectiveness.

Maxillomandibular Advancement for Severe Cases

Maxillomandibular advancement (MMA) surgery offers the most comprehensive anatomical correction for severe sleep apnea cases. This complex procedure involves surgically moving both the upper jaw (maxilla) and lower jaw (mandible) forward, which significantly enlarges the airway space behind the tongue and soft palate.

MMA boasts the highest success rates among surgical sleep apnea treatments, with studies showing 85-100% cure rates in appropriately selected patients. The procedure addresses multiple levels of airway obstruction simultaneously, making it particularly effective for patients with severe anatomical restrictions or those who have failed multiple previous treatments.

The surgical process requires careful pre-operative planning using 3D imaging and computer modeling to determine optimal jaw positioning. During the procedure, surgeons make precise cuts in both jaws, advance them forward by predetermined distances, and secure them with titanium plates and screws. This advancement creates permanent enlargement of the upper airway.

Recovery from MMA surgery is extensive, typically requiring 6-8 weeks for initial healing and up to six months for complete recovery. Patients experience significant facial swelling, difficulty eating solid foods, and temporary numbness. However, the long-term benefits often justify the challenging recovery period for patients with severe sleep apnea.

Minimally Invasive Procedures and Recovery Expectations

Several minimally invasive surgical options provide alternatives to more extensive procedures, particularly suitable for patients with mild to moderate sleep apnea. Pillar implants, for example, involve inserting small polyester rods into the soft palate to reduce vibration and collapse during sleep.

Radiofrequency treatments target specific anatomical areas contributing to airway obstruction. These procedures can address the tongue base, soft palate, or nasal turbinates using controlled thermal energy to create scar tissue that stiffens and reduces tissue volume. Multiple treatment sessions may be necessary to achieve optimal results.

Balloon sinuplasty and septoplasty address nasal obstruction that often compounds sleep apnea symptoms. While these procedures don’t directly treat sleep apnea, improving nasal breathing can enhance the effectiveness of other treatments and reduce overall sleep disruption.

Recovery expectations vary significantly based on the specific procedure chosen. Most minimally invasive treatments allow patients to return to work within a few days, though full healing may take several weeks. Combining surgical interventions with custom sleep device creation often provides comprehensive treatment approaches for complex cases requiring multiple therapeutic modalities.

Lifestyle and Positional Therapies

Weight Management as a Primary Treatment Strategy

Excess weight contributes to sleep apnea severity by narrowing the airway through fat deposits around the neck and throat. Research shows that even a modest 10% reduction in body weight can significantly improve apnea-hypopnea index (AHI) scores in overweight patients.

The mechanism is straightforward: when you lose weight, you reduce tissue mass pressing on your airway during sleep. Studies demonstrate that patients who achieve a 20-pound weight loss often experience a 50% reduction in sleep apnea episodes. This makes weight management one of the most effective long-term strategies for reducing CPAP dependency.

Structured weight loss programs work best when they combine dietary changes with regular exercise. Mediterranean-style diets rich in fruits, vegetables, and lean proteins have shown particular promise. The key is creating sustainable habits rather than pursuing rapid weight loss that patients can’t maintain.

For patients in San Diego’s active lifestyle culture, incorporating outdoor activities like hiking, swimming, or cycling can make weight management more enjoyable. The region’s year-round pleasant weather provides ideal conditions for maintaining consistent exercise routines.

Positional Sleep Therapy for Position-Dependent Sleep Apnea

Approximately 50% of sleep apnea patients experience positional sleep apnea, where symptoms occur primarily when sleeping on their back. This happens because gravity pulls the tongue and soft tissues backward, creating airway obstruction.

Simple positional therapy devices can prevent back sleeping without the complexity of CPAP equipment. Tennis ball shirts, positional pillows, and wearable vibrating devices all work by making back sleeping uncomfortable. These methods show remarkable success rates, with studies indicating 60-70% effectiveness in appropriate candidates.

Modern positional therapy has evolved beyond the traditional “tennis ball in a sock” approach. Commercially available devices use gentle vibration or physical barriers to encourage side sleeping. The sleep assessment process helps determine if you’re a good candidate for positional therapy.

Side sleeping naturally opens the airway and reduces snoring in most patients. For those dealing with mild to moderate positional sleep apnea, this approach can eliminate the need for more invasive treatments entirely.

Myofunctional Therapy and Oropharyngeal Exercises

Myofunctional therapy strengthens the muscles of the tongue, soft palate, and throat through targeted exercises. This approach treats sleep apnea by improving muscle tone in the upper airway, reducing the likelihood of collapse during sleep.

The therapy involves specific tongue and throat exercises performed daily for several months. Patients practice tongue positioning, swallowing techniques, and breathing patterns that promote proper airway function. Research shows myofunctional therapy can reduce AHI scores by up to 50% in carefully selected patients.

A typical program includes tongue strengthening exercises, soft palate training, and nasal breathing techniques. Patients spend 15-20 minutes daily performing these exercises under the guidance of trained therapists. The commitment is significant, but results often appear within 3-4 months of consistent practice.

This approach works particularly well for patients with mild to moderate sleep apnea who want to avoid mechanical devices. It’s especially effective when combined with other lifestyle modifications like weight management and positional therapy.

Sleep Hygiene Optimization for Mild Sleep Apnea

Proper sleep hygiene can significantly impact mild sleep apnea severity. Creating optimal sleep conditions helps reduce airway inflammation and promotes deeper, more restorative sleep patterns.

Key elements include maintaining consistent sleep schedules, creating a cool, dark bedroom environment, and avoiding alcohol or sedatives before bedtime. These substances relax throat muscles, increasing the likelihood of airway collapse. Even moderate alcohol consumption within four hours of sleep can worsen apnea symptoms.

Nasal congestion from allergies or environmental factors can force mouth breathing, which increases sleep apnea risk. Using air purifiers, maintaining proper humidity levels, and treating underlying allergies can improve nasal breathing. San Diego’s coastal climate can trigger specific allergens, making environmental control particularly important for local residents.

Elevating the head of your bed by 30-45 degrees can reduce gravitational effects on the airway. This simple adjustment often provides immediate improvement in symptoms. Combined with other hygiene practices, these modifications create an environment that naturally supports better breathing during sleep.

Emerging and Combination Treatment Approaches

Combination Therapy: Integrating Multiple Treatment Modalities

The most promising frontier in sleep apnea treatment involves combining multiple therapeutic approaches to address the complex nature of airway obstruction. Rather than relying on a single intervention, combination therapy recognizes that sleep apnea often requires a multi-faceted solution.

A typical combination approach might integrate snoring treatment devices with positional therapy and weight management protocols. Studies show that patients using oral appliances alongside targeted weight loss programs achieve apnea-hypopnea index (AHI) reductions of 60-70%, compared to 40-50% with single treatments.

Myofunctional therapy paired with oral appliances represents another effective combination. This approach strengthens tongue and throat muscles while maintaining airway positioning during sleep. Patients in Southern California have reported particularly strong outcomes when combining these therapies with sleep hygiene modifications tailored to the region’s lifestyle patterns.

The key to successful combination therapy lies in timing and coordination. Starting with the least invasive option (often positional training or oral appliances) and gradually adding complementary treatments allows patients to adapt while maximizing therapeutic benefits.

New Technology Solutions in Development

Innovation in sleep apnea treatment continues advancing rapidly, with several technologies showing promise in clinical trials. Hypoglossal nerve stimulation represents the most established emerging treatment, with FDA approval for moderate to severe cases where CPAP has failed.

Newer developments include smart oral appliances equipped with sensors that monitor treatment effectiveness in real-time. These devices can adjust positioning automatically based on breathing patterns, potentially eliminating the trial-and-error approach traditional appliances require.

Biocompatible implants designed to provide structural support to the soft palate are entering late-stage trials. Unlike surgical procedures that remove tissue, these implants maintain natural anatomy while preventing collapse during sleep. Early results suggest significant improvements in both AHI scores and patient comfort.

Targeted muscle stimulation devices represent another frontier. These systems use gentle electrical impulses to strengthen airway muscles during waking hours, potentially reducing the structural weaknesses that contribute to sleep apnea. Clinical trials in California have shown promising results, particularly for patients with mild to moderate obstructive sleep apnea.

Digital therapeutics platforms are also emerging, combining smartphone apps with wearable sensors to deliver personalized treatment protocols. These systems can adjust therapy recommendations based on sleep quality data, environmental factors, and patient feedback.

Alternative Breathing Devices and Nasal Therapies

Beyond traditional CPAP machines, several alternative breathing devices offer different approaches to maintaining airway patency. Expiratory positive airway pressure (EPAP) devices create resistance during exhalation, helping keep airways open without the bulk of traditional CPAP systems.

Nasal dilators and adhesive strips provide simple, non-invasive options for patients with primarily nasal breathing issues. While these solutions work best for mild cases, they can be effective components of comprehensive treatment plans. Many San Diego patients find these particularly useful during allergy seasons when nasal congestion exacerbates sleep breathing problems.

Provent therapy uses small, disposable devices placed over the nostrils to create expiratory resistance. This approach works by using the patient’s own breathing to create positive pressure, maintaining airway opening without external machines or power sources.

Winx therapy represents a newer approach, using a soft mouthpiece connected to a small console that creates gentle suction to advance the tongue and soft palate. This system addresses tongue-based obstructions without requiring the jaw repositioning that oral appliances demand.

When to Consider Experimental Treatment Options

Experimental treatments become viable options when traditional therapies have been thoroughly tried and failed, and when sleep apnea significantly impacts quality of life or poses serious health risks. Patients should have documented CPAP intolerance and unsuccessful trials with at least two alternative treatments before considering experimental approaches.

Good candidates for experimental treatments typically have moderate to severe sleep apnea with AHI scores above 15, clear anatomical factors contributing to airway obstruction, and realistic expectations about potential outcomes and risks. Age, overall health status, and specific anatomical characteristics all influence treatment selection.

Before pursuing experimental options, patients should undergo comprehensive evaluation including updated sleep studies, anatomical assessment through imaging or endoscopy, and consultation with sleep specialists familiar with emerging treatments. Many sleep apnea solana facilities now offer access to clinical trials and experimental treatment protocols.

Risk assessment remains crucial when considering experimental treatments. Patients should understand potential side effects, success rates, reversibility of procedures, and long-term implications. Working with experienced sleep medicine providers ensures appropriate candidate selection and optimal treatment outcomes.

Working with Your Sleep Medicine Team to Find the Right Solution

How to Document CPAP Therapy Failure for Your Doctor

Proper documentation transforms your frustration into actionable medical evidence. Start by keeping a detailed sleep diary that tracks more than just hours slept. Record nightly mask leakage incidents, the number of times you removed the device, and morning symptoms like headaches or grogginess. Most modern CPAP machines store compliance data, but your subjective experience matters equally.

Track specific problems systematically over at least 4-6 weeks. Note claustrophobic episodes, skin irritation locations, and whether certain sleeping positions worsen discomfort. Document any physical side effects like bloating from swallowed air or dry mouth despite using a humidifier. Include partner observations about continued snoring or breathing interruptions while using the device.

Photograph visible skin irritation or pressure sores from masks. These visual records help sleep specialists understand the severity of fit issues. Create a simple chart rating your energy levels, mood, and daytime sleepiness on a 1-10 scale. This baseline data becomes crucial when comparing alternative treatment outcomes later.

Questions to Ask When Exploring Treatment Alternatives

Approach your sleep medicine consultation strategically by preparing specific questions about each alternative option. Ask about the success rates for patients with your particular AHI (Apnea-Hypopnea Index) score and sleep apnea severity. Understanding candidacy requirements helps narrow realistic options quickly.

Inquire about treatment timelines and what “success” looks like for each alternative. Oral appliances typically show improvement within 2-4 weeks, while surgical options may require 3-6 months for full results. Ask about combination approaches since some patients benefit from paired treatments like oral appliances plus positional therapy.

Discuss potential side effects thoroughly. Oral appliances can cause jaw discomfort initially, while surgical options carry standard procedural risks. Understanding both short-term adjustment periods and long-term considerations helps set realistic expectations. Ask about backup plans if your first alternative choice doesn’t provide adequate symptom relief.

Request specific outcome measurements your doctor will use to evaluate treatment success. Some providers track AHI reduction, while others focus on symptom improvement and quality of life metrics. Understanding these criteria helps you participate actively in monitoring your progress.

Insurance Coverage Considerations for Alternative Treatments

Navigate insurance approval by understanding the documentation requirements for alternative sleep apnea treatments. Most insurers require proof of CPAP therapy failure, typically defined as inability to use the device for at least four hours per night on 70% of nights during a 30-day period. Your compliance data and documented symptoms become essential supporting evidence.

Oral appliances generally receive coverage after documented CPAP failure, but some insurers require specific diagnostic criteria or physician specializations. Sleep medicine physicians or dentists with sleep medicine training typically need to provide the prescription and fitting. Pre-authorization often takes 2-4 weeks, so start this process early.

Surgical procedures face more stringent coverage criteria. Insurance companies typically require demonstration that conservative treatments failed and that anatomical factors make surgery likely to succeed. Sleep studies, imaging studies, and specialist evaluations become part of the approval process. Understanding your specific plan’s requirements prevents delays and unexpected costs.

Consider out-of-network costs if your preferred specialist doesn’t accept your insurance. Some snoring treatment providers offer payment plans or work with healthcare financing companies to make alternative treatments more accessible.

Creating a Personalized Treatment Plan That Works

Successful sleep apnea management requires a treatment plan tailored to your specific anatomy, lifestyle, and preferences. Work with your sleep medicine team to identify the primary factors contributing to your airway obstruction. Patients with primarily tongue-based obstructions may respond better to oral appliances, while those with soft palate issues might benefit more from surgical interventions.

Consider your daily routines and travel requirements when selecting alternatives. Business travelers might prefer oral appliances over CPAP machines for portability, while those with stable home routines might consider combination therapies that require more equipment setup.

Build in regular follow-up schedules with objective measurement tools. Many patients benefit from home sleep studies 3-6 months after starting alternative treatments to verify effectiveness. Your treatment plan should include clear milestones for evaluation and adjustment.

Remember that finding the right sleep apnea solution often requires patience and persistence. When CPAP therapy fails, working collaboratively with experienced sleep medicine professionals opens doors to effective alternatives that can restore your quality sleep and overall health. The journey to better sleep may take time, but the improvement in your daily energy and long-term health outcomes makes the effort worthwhile.
