Distance to Specialist Medical Care and Diagnosis of Obstructive Sleep Apnea in Rural Saskatchewan

Establishing a telehealth model addressing paediatric sleep health in remote and rural Northern Territory Australia: Overcoming the distance barrier

AIM

This study examined the outcomes of a telehealth model for sleep health assessment among Indigenous and non-Indigenous children residing in remote and regional communities at the Top End Northern Territory (NT) of Australia.

METHODS

Video telehealth consultation, that included clinical history and relevant physical findings assessed virtually with an interstate paediatric sleep physician was conducted remotely. Polysomnography (PSG) and therapeutic interventions were carried out locally at Darwin, NT. The study participants were children referred between 2015 and 2020.

RESULTS

Of the total 812 children referred for sleep assessment, 699 underwent a diagnostic PSG. The majority of patients were female (63%), non-Indigenous (81%) and resided in outer regional areas (88%). Indigenous children were significantly older and resided in remote or very remote locations (22% vs. 10%). Referral patterns differed according to locality and Indigenous status - (non-Indigenous via private (53%), Indigenous via public system (35%)). Receipt of referrals to initial consultation was a median of 16 days and 4 weeks from consult to PSG. Remote children had slightly longer time delay between the referral and initial consult (32 vs. 15 days). Fifty one percent were diagnosed to have OSA, 27% underwent adenotonsillectomy and 2% were prescribed with CPAP therapy.

CONCLUSIONS

This study has demonstrated that a telehealth model can be an effective way in overcoming logistical barriers and in providing sleep health services to children in remote and regional Australia. Further innovative efforts are needed to improve the service model and expand the reach for vulnerable children in very remote communities.

Parental experiences in navigating health services for paediatric residual obstructive sleep apnoea: An exploratory qualitative descriptive study

OBJECTIVES

To explore parents' experiences and perceptions regarding engagement in health services for managing residual paediatric obstructive sleep apnoea (OSA) across levels of care.

METHODS

Qualitative description guided study design. Data were collected through semi-structured interviews with parents of children diagnosed with residual OSA at a university-based sleep clinic. The relevant literature informed the interview guide and was piloted before data collection. Inductive, manifest content analysis was used to describe parents' perceptions and experiences using data-driven categories and sub-categories. Several strategies were employed to ensure rigour in this study.

RESULTS

Eight interviews were conducted. Parents' views were organized into five categories: awareness of the sleep issue, interaction with non-sleep specialists, interaction with sleep specialists, interaction with dental professionals, and further actions and support. Parents reported several engagement issues due to their interactions with different care providers. These issues included having to personally identify and raise the sleep problem, feeling that care providers did not take this problem seriously, waiting for an extended period to be referred for sleep services, and receiving conflicting or insufficient treatment recommendations. Overall, parents perceived that their actions and the services received across levels of care were not effective enough to address paediatric OSA.

CONCLUSION

Based on this exploratory qualitative descriptive research, along with developing evidence-based clinical guidelines for paediatric OSA screening and management tailored to different levels of care, strategies intended to improve the engagement of patients and care providers in addressing paediatric OSA should be developed and empirically tested.

Experiences of care-seeking by schizophrenia patients with delayed diagnosis and treatment in rural China: A qualitative study

BACKGROUND

Patients with schizophrenia in rural areas of China face severe delays in getting appropriate treatment due to poverty, transportation, and limited availability of mental healthcare services. However, the experiences of care-seeking among patients with delayed diagnosis and treatment in rural areas remain poorly understood, and it remains unclear how these experiences influence patients' medical mistrust or expectations of care. This study aims to fill that void.

METHODS

We applied a qualitative phenomenological method. Patients were recruited through purposive sampling at a psychiatric hospital in Harbin, China. Semi-structured, one-to-one interviews were conducted, guided by an interview outline. Thematic analysis was performed using Colaizzi's seven-step method.

RESULTS

Data saturation was achieved after interviewing 13 participants aged 21 to 53 years. Three themes with eight subthemes were identified: (i) Barriers to seeking care, (ii) Feelings for psychiatric treatment, and (iii) Demand for mental healthcare. Several factors that may impede the timely diagnosis and treatment were identified, including patients, physicians, and institutions. The participants described their feelings of adverse treatment experiences, as well as expectations arising from this process. It predominantly covers awareness of the disease, supportive access to care, and geographic accessibility of services.

CONCLUSION

Patients with delayed diagnosis and treatment in rural areas often have negative experiences and various needs for mental health services in the pursuit of effective treatments. Policymakers and health planners should seriously consider the current challenges in rural mental healthcare to develop comprehensive strategies for improving prehospital delays and medical experience for this group of patients.

Relationship between sleep apnea and hospital readmission in rural and urban populations

OBJECTIVES

The aims of this study were to evaluate geographic differences in obstructive sleep apnea (OSA) prevalence, to determine if readmissions were more likely among rural patients with OSA than others, and to model predictors, including diagnosed OSA, of 30, 60, and 90-day acute-care readmissions.

DESIGN

This cohort study employed a secondary analysis of data extracted from the electronic health record shared by all hospitals in a north Texas healthcare system.

SAMPLE

The sample consisted of records associated with 472,503 adult patients admitted to any of the study system's acute-care facilities from 2016 through 2019.

MEASUREMENTS

Measurements consisted of case-level health information, including admissions, demographic variables, payors, diagnoses, screens, and physician orders.

RESULTS

OSA was significantly related to hospital readmission when considered in isolation but did not significantly predict readmission when modeled with plausible covariates. Screening rates for OSA did not vary by geography. Differences in rural/urban-suburban OSA prevalence were not statistically significant.

CONCLUSIONS

Findings contrast with previous suggestions that OSA plays an independent role in hospital readmissions or that rural resident may be disadvantaged regarding services that support the OSA diagnosis. Prevalence and screening rates were almost identical in urban and rural populations.

Environmental Benefits of Sleep Apnoea Detection in the Home Environment

Sleep Apnoea (SA) is a common chronic illness that affects nearly 1 billion people around the world, and the number of patients is rising. SA causes a wide range of psychological and physiological ailments that have detrimental effects on a patient’s wellbeing. The high prevalence and negative health effects make SA a public health problem. Whilst the current gold standard diagnostic procedure, polysomnography (PSG), is reliable, it is resource-expensive and can have a negative impact on sleep quality, as well as the environment. With this study, we focus on the environmental impact that arises from resource utilisation during SA detection, and we propose remote monitoring (RM) as a potential solution that can improve the resource efficiency and reduce travel. By reusing infrastructure technology, such as mobile communication, cloud computing, and artificial intelligence (AI), RM establishes SA detection and diagnosis support services in the home environment. However, there are considerable barriers to a widespread adoption of this technology. To gain a better understanding of the available technology and its associated strength, as well as weaknesses, we reviewed scientific papers that used various strategies for RM-based SA detection. Our review focused on 113 studies that were conducted between 2018 and 2022 and that were listed in Google Scholar. We found that just over 50% of the proposed RM systems incorporated real time signal processing and around 20% of the studies did not report on this important aspect. From an environmental perspective, this is a significant shortcoming, because 30% of the studies were based on measurement devices that must travel whenever the internal buffer is full. The environmental impact of that travel might constitute an additional need for changing from offline to online SA detection in the home environment.

Provider Perspectives on Sleep Apnea from Appalachia: A Mixed Methods Study

West Virginia (WV) has the highest rates of obesity and cardiopulmonary disease in the United States (U.S.). Recent work has identified a significant care gap in WV for obstructive sleep apnea (OSA). This OSA care gap likely has significant health implications for the region given the high rates of obesity and cardiopulmonary disease. The purpose of this mix methods study was to identify barriers that contribute to the rural OSA care disparity previously identified in WV. Methods: This study used mixed methods to evaluate the barriers and facilitators to management of OSA at Federally Qualified Health Centers serving communities in southern WV. Focus groups were conducted at federally qualified health centers with providers serving Appalachian communities. Participants also completed the validated Obstructive Sleep Apnea Knowledge and Attitudes (OSAKA) questionnaire to gain insight into provider knowledge and beliefs regarding OSA. EMR analysis using diagnostic codes was completed at the sites to assess OSA prevalence rates. The same individual served as the interviewer in all focus group sessions to minimize interviewer variability/bias. Our team checked to ensure that the professional transcriptions were correct and matched the audio via spot checks. Results: Themes identified from the focus groups fell into three broad categories: (1) barriers to OSA care delivery, (2) facilitators to OSA care delivery, and (3) community-based care needs to optimize management of OSA in the targeted rural areas. Questionnaire data demonstrated rural providers feel OSA is an important condition to identify but lack confidence to identify and treat OSA. Evaluation of the electronic medical record demonstrates an even larger OSA care gap in these rural communities than previously described. Conclusion: This study found a lack of provider confidence in the ability to diagnose and treat OSA effectively and identified specific themes that limit OSA care in the communities studied. Training directed toward the identified knowledge gaps and on new technologies would likely give rural primary care providers the confidence to take a more active role in OSA diagnosis and management. An integrated model of care that incorporates primary care providers, specialists and effective use of modern technologies will be essential to address the identified OSA care disparities in rural WV and similar communities across the U.S. Community engaged research such as the current study will be essential to the creation of feasible, practical, relevant and culturally competent care pathways for providers serving rural communities with OSA and other respiratory disease to achieve health equity.

Treatment outcomes among rural and urban patients with obstructive sleep apnea: a prospective cohort study

STUDY OBJECTIVES

To determine whether adherence to continuous positive airway pressure (CPAP) in adults with uncomplicated OSA differs by rural versus urban residential address.

METHODS

In this prospective cohort study, we recruited adults who initiated CPAP for uncomplicated OSA that was diagnosed by a physician using sleep specialist-interpreted diagnostic testing. Participants were classified as urban (community size > 100,000) or rural by translating residential postal code into geographic census area. The primary outcome was mean daily hours of CPAP use compared between rural and urban patients. Secondary outcomes included: the proportion of patients who were adherent to CPAP; change in Epworth Sleepiness Scale (ESS) score; change in EuroQOL-5D score; and Visit-Specific Satisfaction Instrument score. All outcomes were measured three months after CPAP initiation.

RESULTS

We enrolled 242 patients (100 rural) with mean (SD) age 51 (13) years and respiratory event index 24 (18) events/hour. Mean (95% CI) CPAP use was 3.19 (2.8,3.58) hours/night and 35% were CPAP-adherent, with no difference between urban and rural patients. Among the 65% of patients who were using CPAP at three months, mean CPAP use was 4.89 (4.51,5.28) hours/night and was not different between rural and urban patients. Improvement in ESS and patient satisfaction were similar between groups, but EuroQOL-5D score improved to a greater extent in rural patients. Urban or rural residence was not associated with CPAP adherence in multivariable regression analysis.

CONCLUSIONS

Rural versus urban residence was not associated with differences in CPAP adherence when guided by specialist-interpreted diagnostic sleep testing.

An evaluation of rural-urban disparities in treatment outcomes for obstructive sleep apnoea: study protocol for a prospective cohort study

Background

Obstructive sleep apnoea (OSA) is a common and treatable chronic condition that is associated with significant morbidity and economic cost. Geography is increasingly being recognised as a barrier to diagnosis and treatment of many chronic diseases; however, no study to date has investigated the impact of place of residence on health outcomes in OSA.

Objective

The purpose of this study is to determine whether treatment outcomes for patients initiating continuous positive airway pressure (CPAP) for OSA differ between those who live in urban versus rural settings.

Methods

A prospective cohort design will be used. Participants will be recruited through community-based CPAP providers and assigned to either the rural or urban cohort based on residential postal code. The primary outcome will be the difference in nightly hours of CPAP use between the two groups, measured 3 months after initiation of therapy. Secondary outcomes will include symptoms, quality of life, patient satisfaction and patient-borne costs.

Anticipated results

This study will determine whether there are differences in CPAP adherence or patient-reported outcomes between rural and urban patients with OSA. These results will highlight potential challenges with providing OSA care in rural populations and may inform health interventions to reduce urban-rural inequities.

Global burden of sleep-disordered breathing and its implications

One-seventh of the world's adult population, or approximately one billion people, are estimated to have OSA. Over the past four decades, obesity, the main risk factor for OSA, has risen in striking proportion worldwide. In the past 5 years, the WHO estimates global obesity to affect almost two billion adults. A second major risk factor for OSA is advanced age. As the prevalence of the ageing population and obesity increases, the vulnerability towards having OSA increases. In addition to these traditional OSA risk factors, studies of the global population reveal select contributing features and phenotypes, including extreme phenotypes and symptom clusters that deserve further examination. Untreated OSA is associated with significant comorbidities and mortality. These represent a tremendous threat to the individual and global health. Beyond the personal toll, the economic costs of OSA are far-reaching, affecting the individual, family and society directly and indirectly, in terms of productivity and public safety. A better understanding of the pathophysiology, individual and ethnic similarities and differences is needed to better facilitate management of this chronic disease. In some countries, measures of the OSA disease burden are sparse. As the global burden of OSA and its associated comorbidities are projected to further increase, the infrastructure to diagnose and manage OSA will need to adapt. The use of novel approaches (electronic health records and artificial intelligence) to stratify risk, diagnose and affect treatment are necessary. Together, a unified multi-disciplinary, multi-organizational, global approach will be needed to manage this disease.
