National patterns of physician management of sleep apnea and treatment among patients with hypertension

Prevalence of Obstructive Sleep Apnea Among Veterans and Nonveterans

PURPOSE

Understanding disease prevalence can inform treatment and resource needs across populations. This study aimed to identify the prevalence of sleep apnea (OSA) among veterans and nonveterans.

DESIGN

The national Comparative Health Assessment Interview Study, cross-sectional survey using probability-based sampling frames.

SETTING

Surveys completed by Internet or phone.

SUBJECTS

15,166 veterans (40% response rate) and 4,654 nonveterans (57% response rate).

MEASURES

Self-report of healthcare provider-based diagnosis of OSA.

ANALYSIS

Calculation of prevalence of OSA using statistical weighting to allow for direct comparison between veterans and nonveterans. Secondary analyses evaluated OSA by deployment status among veterans and compared average age of OSA diagnosis and differences in OSA prevalence among veterans and nonveterans stratified by gender, marital status, race/ethnicity, and posttraumatic stress disorder diagnosis.

RESULTS

OSA diagnosis was more than twice as prevalent among veterans (21%, 95% CI 20%-22%) than nonveterans (9%, 95% CI 8%-10%; aOR: 2.56, 95% CI 2.22-2.95, P < .001). Deployment was associated with higher odds of OSA among veterans (aOR: 1.64, 95% CI 1.43-18.7, P < 001.) Veterans were diagnosed with OSA on average 5 years earlier than nonveterans.

CONCLUSION

Veterans have a high prevalence rate of OSA, highlighting the importance of veterans' access to treatment. OSA is likely underdiagnosed in nonveterans, particularly among racial/ethnic minoritized groups. Future research should investigate disparities in access to diagnostic testing for racial/ethnic minority nonveterans and/or risk factors for OSA among racial/ethnic minority veterans. The increased odds of OSA among those with PTSD highlights in the importance of early referral for OSA testing by providers as well as development of trauma-informed strategies to promote OSA treatment adherence. Limitations include a bias toward underestimation of true disease prevalence due to self-report of diagnosis.

Ethical and Policy Implications of Racial and Ethnic Healthcare Disparities in Sleep Health

Despite efforts in recent years, including in policy and research, to address health disparities in the United States, many of those disparities continue to fester in marginalized racial/ethnic populations. Understanding sleep health disparities is critical in understanding the health and wellness of these groups. Using obstructive sleep apnea (OSA) in Black populations as a focus, this paper presents the role of race and ethnicity in the clinical understanding of sleep health-related issues by medical practitioners and the implications of the lack of clear policies or best practices to guide medical practitioners' attempts to meet sleep-related needs of marginalized racial/ethnic populations. Furthermore, the knowledge gap may be further complicated by the poor understanding and integration of existing evidence with the many, complex, sleep-associated co-morbidities. Policymaking in this area ought to be based on the ethical implications of disparate sleep-related health outcomes by race and ethnicity. So, we conclude by offering recommendations for developing ethically sound policies for addressing sleep problems in marginalized racial and ethnic populations.

Protocol for a pragmatic trial testing a self-directed lifestyle program targeting weight loss among patients with obstructive sleep apnea (POWER Trial)

BACKGROUND

Obesity comprises the single greatest reversible risk factor for obstructive sleep apnea (OSA). Despite the potential of lifestyle-based weight loss services to improve OSA severity and symptoms, these programs have limited reach. POWER is a pragmatic trial of a remote self-directed weight loss care among patients with OSA.

METHODS

POWER randomizes 696 patients with obesity (BMI 30-45 kg/m2) and recent diagnosis or re-confirmation of OSA 1:1 to either a self-directed weight loss intervention or usual care. POWER tests whether such an intervention improves co-primary outcomes of weight and sleep-related quality of life at 12 months. Secondary outcomes include sleep symptoms, global ratings of change, and cardiovascular risk scores. Finally, consistent with a hybrid type 1 approach, the trial embeds an implementation process evaluation. We will use quantitative and qualitative methods including budget impact analyses and qualitative interviews to assess barriers to implementation.

CONCLUSIONS

The results of POWER will inform population health approaches to the delivery of weight loss care. A remote self-directed program has the potential to be disseminated widely with limited health system resources and likely low-cost.

A Scoping Review of Sleep Apnea: Where Do We Stand?

Obstructive sleep apnea (OSA), a condition in which there is a recurrent collapse of the upper airway while sleeping, is a widespread disease affecting 5% to 10% people worldwide. Despite several advances in the treatment modalities for OSA, morbidity and mortality remain a concern. Common symptoms include loud snoring, gasping for air during sleep, morning headache, insomnia, hypersomnia, attention deficits, and irritability. Obese individuals, male gender, older age (65+), family history, smoking, and alcohol consumption are well recognized risk factors of OSA. This condition holds the ability to increase inflammatory cytokines, cause metabolic dysfunction, and increase the sympathetic output, all of which exacerbate OSA due to their effect on the cardiovascular system. In this review, we discuss its brief history, risk factors, complications, treatment modalities, and the role of clinicians in curbing its risk.

How the National Ambulatory Medical Care Survey has been used to identify health disparities in the care of patients in the United States

BACKGROUND

Healthcare disparities negatively impact patient health outcomes; addressing disparities could improve quality of life and decrease overall healthcare cost. The National Ambulatory Medical Care Survey (NAMCS) is an objective and reliable source for collecting information on United States (U.S.) ambulatory medical care service visits and may be a useful tool for identifying potential disparities in care.

OBJECTIVE

The purpose of this literature review is to describe studies utilizing NAMCS to capture U.S. healthcare disparities.

METHODS

PubMed was searched for scientific articles that utilized NAMCS to determine health disparities in the U.S. The keywords queried included "NAMCS" or "National Ambulatory Medical Care Survey" and "disparity" or "disparities" as a pair or additionally paired with one of the following: "race", "ethnicity", "age", "gender", "geography", or "insurance".

RESULTS

66 studies were found that incorporated NAMCS data from 1980-2016 into their methods to measure outcomes relating to health disparities. Disparities were found in the following categories: race/ethnicity, geographic location, age, insurance type, gender, specialist care versus primary care, body habitus, and preexisting conditions affecting patient outcomes. Disparities were identified in pain management, neurology, dermatology, psychiatry, patient communication access, and non-specialty specific or primary care visits related to disease conditions, screening, and treatment plans.

LIMITATIONS

Only PubMed was utilized as a search engine and may not encompass all studies on NAMCS and health disparities. NAMCS is a cross-sectional database and does not allow for longitudinal analyses.

CONCLUSIONS

NAMCS may be an underused tool given the limited number of articles that identify health disparities using it. Research studies utilizing NAMCS may identify potential disparities ultimately leading to better healthcare outcomes.
