A review of psychosocial factors and personality in the treatment of obstructive sleep apnoea

Psychometric Properties of the Turkish Version of Self-Efficacy Measure for Sleep Apnea (SEMSA) Instrument

BACKGROUND

Determining the self-efficacy perceptions of obstructive sleep apnea (OSA) patients has a key role in health care practices. With further evaluation, the Self-Efficacy Measure for Sleep Apnea (SEMSA) could serve as a useful scale to develop specific interventions to increase self-efficacy in patients with OSA during the acceptance and maintenance of continuous positive airway pressure (CPAP) therapy.

OBJECTIVE

The aim of this study is to translate the SEMSA into Turkish and to evaluate the psychometric properties of the translation.

METHODS

This cross-sectional study was carried out with a sample of patients recently diagnosed with CPAP-naïve OSA. Linguistic and content validity of the scale were evaluated, while exploratory factor analysis and 2-level confirmatory factor analysis were used for validity. Internal consistency and test-retest methods were used in reliability analyses.

RESULTS

The mean (SD) age of the patients with OSA was 51.36 (11.29), and 68% were male. The item factor loads obtained as a result of the confirmatory factor analysis ranged from 0.44 to 0.94, confirming the three-factor structure of the instrument. The Cronbach's α coefficient of the scale was found to be 0.90. Measurements made within the scope of test-retest analysis were found to be related and consistent results were obtained in the intervening time (P < .01).

CONCLUSIONS

In this study, the Turkish version of SEMSA was found to be a valid and reliable tool and it could be used to evaluate the adherence-related cognition in Turkish patients with OSA on CPAP therapy.

Personality traits and pre-treatment beliefs and cognitions predicting patient adherence to continuous positive airway pressure: A systematic review

Adherence to Continuous Positive Airway Pressure (CPAP) for obstructive sleep apnoea (OSA) can be improved by behavioural interventions which modify patients' beliefs and cognitions about OSA, CPAP, and themselves. We have conducted the first systematic review of the literature on beliefs and cognitions held before starting treatment, and personality (which influences the former) that predict the decision to purchase or start CPAP, or CPAP adherence one month or more after CPAP initiation. A systematic search and screen of articles identified 21 eligible publications from an initial 1317. Quality assessment performed using an adapted Newcastle-Ottawa Scale demonstrated that 13 (62%) studies were poor quality and only seven (33%) were high quality. Eighteen factors, such as self-efficacy (confidence) in using CPAP and value placed on health predicted CPAP adherence; however, for only six (33%), utility as an intervention target is known, from calculation of individual predictive power. Studies did not use new behavioural frameworks effective at explaining adherence behaviours, nor did they interview patients to collect in-depth data on barriers and facilitators of CPAP use. Future studies cannot have these limitations if high quality evidence is to be generated for intervention development, which is currently sparse as highlighted by this review.

[Factors affecting adherence to CPAP therapy in patients with obstructive sleep apnea syndrome]

OBJECTIVE

Analysis of factors affecting adherence to continuous positive airway pressure (CPAP) therapy in patients with obstructive sleep apnea (OSA).

MATERIAL AND METHODS

The literature search was carried out using the databases PubMED, Google Scholar, E-library, Cyberleninka for the period 2013-2023 and included reviews and original articles.

RESULTS

The main groups of factors affecting adherence to CPAP therapy in patients with OSA have been established. These include sociodemographic and socioeconomic factors, the severity of OSA and the severity of clinical symptoms, and psychosocial factors. Strategies that can improve adherence were identified (educational technologies for patients, telemedicine technologies, behavioral therapy, modern technical interventions).

CONCLUSION

Factors that improve adherence to CPAP therapy are high levels of education and income, more severe OSA forms accompanied by daytime sleepiness, support from the patient's spouse and social support. Factors such as low levels of education and income, smoking, symptoms of depression and hypochondria, as well as side-effects worsen adherence to CPAP therapy, including refusal to continue treatment. It should be noted that all the identified factors are very closely associated with each other, so it is necessary to evaluate them comprehensively in each patient with OSA.

Nocturnal positive pressure ventilation improves relationship satisfaction of patients with OSA and their partners

OBJECTIVE

Continuous positive airway pressure (CPAP) ventilation is considered the therapeutic standard for obstructed sleep apnea (OSA). Therapy success may also be affected by the patient's bed partner. A questionnaire was developed and tested that measures the attitude of the bed partner towards CPAP therapy and relationship effects.

METHODS

A new questionnaire to capture bed partners' attitude towards CPAP mask therapy was used with an anonymous sample of 508 bed partners. Possible constructs underlying the attitude of the bed partner towards mask appearance have been investigated by means of a Principal Components Analysis.

RESULTS

The survey revealed bed partners' positive attitude towards their partner's CPAP therapy (over 90% of bed partners were happy with the therapy, over 75% would recommend the therapy). Importantly, the bed partners' satisfaction with the relationship increased significantly during CPAP therapy (before therapy: 49% were satisfied, after therapy initiation: 70%; p<.001). There was a strong correlation between support for CPAP therapy and improved sleep quality of bed partners (r = 0.352, p>.001). Furthermore, the validation of the questionnaire through principal components analysis revealed three major factors: Attitude (of the bed partner towards CPAP therapy), Looks (of the mask perceived by the bed partner), Intimacy (effect of CPAP therapy on relationship and intimacy).

CONCLUSION

Both, the OSA patient and the bed partner benefit from CPAP therapy. This is the first bed partner questionnaire - interviewing the bed partner alone and anonymously - that showed that CPAP therapy also positively influences the relationship. We recommend that the bed partner be involved in the CPAP treatment from the start of therapy.

Comparative evaluation of the efficacy of customized maxillary oral appliance with mandibular advancement appliance as a treatment modality for moderate obstructive sleep apnea patients-a randomized controlled trial

BACKGROUND

Obstructive sleep apnea (OSA) is quite common among the adult population, according to recent epidemiological studies. The most frequently suggested alternate treatment for mild to moderate OSA is oral appliances (OA). The purpose of the present study was to assess as well as compare the effectiveness of custom-made maxillary oral appliances against mandibular advancement appliances in the care of individuals suffering from moderate obstructive sleep apnea.

METHODS

A prospective interventional research was carried out with 40 participants. Polysomnography (PSG) was done and the participants with an apnea-hypopnea index (AHI) >15-30 were involved in the research. Study participants were randomly split up into two test groups: group I was the "Control Group" (group treated with a mandibular advancement device (MAD), n=20), while group II was exposed to a "customized maxillary oral appliance" (CMOA, n=20). Both groups had reference measures for AHI, blood oxygen saturation (SpO2), oro-nasal airflow via respiratory disturbance index (RDI), and the Epworth Sleepiness Scale (ESS). Appliances were fabricated and delivered to the respective study group participants. PSG was again conducted after a period of 1 and 3 months of appliance delivery and re-evaluation was done for all the parameters and was compared with reference measurements. The facts were analyzed using descriptive and analytical statistical methods. The statistical program utilized in the study was "SPSS (Statistical Package for Social Sciences) Version 20.1." After 1 and 3 months, the statistical significance between the two study groups was assessed at P<0.05.

RESULTS

The analysis of mean AHI, SPO2, RDI, and ESS for both test groups manifested statistically significant measures (P<0.001). The study results revealed a statistically significant depletion in mean AHI scores, improvement in mean SPO2 scores, and reduction in mean RDI scores and ESS scores when compared with reference measurements to 1 month, 1 to 3 months, and between reference measurements and 3 months.

CONCLUSION

The CMOA was effective in managing moderate OSA and has great therapeutic potential. It can be an option for the MAD for treating patients suffering from moderate obstructive sleep apnea.

Telehealth Technology Application in Enhancing Continuous Positive Airway Pressure Adherence in Obstructive Sleep Apnea Patients: A Review of Current Evidence

Obstructive sleep apnea (OSA) is a common type of sleep-disordered breathing associated with multiple comorbidities. Continuous positive airway pressure (CPAP) is the first choice for moderate-severe OSA but poor compliance brings a great challenge to its effectiveness. Telehealth interventions ease the follow-up process and allow healthcare facilities to provide consistent care. Fifth-generation wireless transmission technology has also greatly rationalized the wide use of telemedicine. Herein, we review the efficacy of the telehealth system in enhancing CPAP adherence. We recommend applying telemonitoring in clinical practice and advocate the development of a biopsychosocial telemedicine model with the integration of several interventions. Big databases and promising artificial intelligent technologies make clinical decision support systems and predictive models based on these databases possible.

Effect of informationmotivationbehavior skills on adherence of continuous positive airway pressure therapy in patients with obstructive sleep apnea hypopnea syndrome

OBJECTIVES

Obstructive sleep apnea hypopnea syndrome (OSAHS) is a common disease that seriously affects health. Continuous positive airway pressure (CPAP) therapy is the preferred treatment for moderate-to-severe OSAHS patients. However, poor adherence to CPAP is a major obstacle in the treatment of OSAHS. Information-motivation-behavioral (IMB) skills, as a kind of mature technology to change the behavior, has been used in various health areas to improve treatment adherence. This study aims to explore the effects of the IMB skills intervention on CPAP adherence in OSAHS patients.

METHODS

Patients who were primary diagnosed with moderate-to-severe OSAHS were randomly divided into the IMB group (n=62) and the control group (n=58). The patients in the IMB group received CPAP therapy and the IMB skills intervention for 4 weeks. The patients in the control group received CPAP therapy and a usual health care provided by a registered nurse. We collected the baseline data of the general information, including age, sex, body mass index (BMI), the Epworth Sleepiness Scale (ESS) score, the Hospital Anxiety and Depression Scale (HADS) score, and indicators about disease severity [apnea-hypopnea index (AHI), percentage of time with arterial oxygen saturation SaO2<90% (T90), average SaO2, lowest SaO2, arousal index]. After CPAP titration, we collected CPAP therapy-relevant parameters (optimal pressure, maximum leakage, average leakage, 95% leakage, and residual AHI), score of satisfaction and acceptance of CPAP therapy, and score of willingness to continue CPAP therapy. After 4 weeks treatment, we collected the ESS score, HADS score, CPAP therapy-relevant parameters, effective CPAP therapy time per night, CPAP therapy days within 4 weeks, CPAP adherence rate, score of satisfaction and acceptance of CPAP therapy, and score of willingness to continue CPAP therapy. Visual analog scale (VAS) of 0-5 was used to evaluate the satisfaction and acceptance of IMB intervention measures in the IMB group.

RESULTS

There were no significant differences in the baseline level of demographic parameters, ESS score, HADS score, disease severity, and CPAP therapy related parameters between the IMB group and the control group (all P>0.05). There were no significant differences in score of willingness to continue CPAP therapy, as well as score of satisfaction and acceptance of CPAP therapy after CPAP titration between the IMB group and the control group (both P>0.05). After 4 weeks treatment, the ESS score, HADS score, maximum leakage, average leakage, and 95% leakage of the IMB group were significantly decreased, while the score of satisfaction and acceptance of CPAP therapy and willingness to continue CPAP therapy of the IMB group were significantly increased (all P<0.05); while the above indexes in the control group were not different before and after 4 weeks treatment (all P<0.05). Compared with the control group, the ESS score, HADS score, maximum leakage, average leakage, and 95% leakage of the IMB group after 4 weeks treatment were significantly lower (all P<0.05); the effective CPAP therapy time, CPAP therapy days within 4 weeks, score of satisfaction and acceptance of CPAP therapy, score of willingness to continue CPAP therapy of the IMB group were significantly higher (all P<0.05). The rate of CPAP therapy adherence in 4 weeks of the IMB group was significantly higher than that of the control group (90.3% vs 62.1%, P<0.05). The VAS of overall satisfaction with IMB skills intervention measures was 4.46±0.35.

CONCLUSIONS

IMB skills intervention measures can effectively improve the adherence of CPAP therapy in OSAHS patients, and is suitable for clinical promotion.

The Effect of Telemonitoring (TM) on Improving Adherence with Continuous Positive Airway Pressure (CPAP) in Obstructive Sleep Apnoea (OSA): A Service Improvement Project (SIP)

The benefits of CPAP demonstrated in clinical trials are difficult to deliver in real life due to the lack of adherence. We analysed the effect of a Telemonitoring (TM)-related intervention on adherence as part of a Service Improvement Project (SIP) analysed as a retrospective cohort study. The ‘historical control’ (HC) cohort (followed up in conventional clinics) included all patients who commenced on CPAP between 1 February and 30 April 2019 (n = 142). The ‘telemonitoring’ (TM) cohort included all patients who commenced on CPAP between 1 May and 31 July 2019 (n = 166). Adherence was checked at 30 days (baseline) and 73 days for both cohorts. Wilcoxon—Rank test was used for statistical analysis (results reported as mean ± SEM). Both cohorts had similar adherence at the 30-day baseline, compared to a significantly lower adherence in the HC-cohort at 73 days (55.7 ± 3.0 vs. 51.8 ± 3.2% of days ≥ 4 h: p = 0.0072, average usage 255 ± 12.8 vs. 236 ± 13.7 min: p = 0.0003). There was a significantly higher adherence in the TM-cohort at 73 days (50.8 ± 2.5 vs. 56.1 ± 2.9% of days ≥ 4 h: p = 0.0075; average usage 234 ± 10.4 vs. 252 ± 12.1 min: p = 0.0456). Telemonitoring-feedback is effective at improving adherence with CPAP, suggesting its potential beneficial role in the community setting, particularly in the post-COVID reality of increased remote consultations.

Comparative evaluation of the efficacy of customized maxillary oral appliance with mandibular advancement appliance as a treatment modality for moderate obstructive sleep apnea patients-protocol for a randomized controlled trial

Background

Obstructive sleep apnea (OSA) is due to the obstruction of the upper airway during sleep. This condition is often associated with multiple symptoms and co-morbidities. There are many treatment options mentioned in the literature to manage OSA, among which interventional option of continuous positive airflow (CPAP) and non-interventional option, i.e., mandibular advancement device (MAD), which is an oral appliance (OA), are the most preferred ones. This study aims to evaluate the efficacy of customized maxillary oral appliances with mandibular advancement devices in moderate OSA patients.

Methods

A prospective interventional study with a randomized controlled trial will be carried out involving 40 participants (sample size), with an apnea-hypopnea index (AHI) > 15–30, recorded on polysomnography (PSG). Study participants will be randomly divided into the following treatment groups: control group or group subjected to mandibular advancement device (MAD, n=20) and second group subjected to customized maxillary oral appliance (CMOA, n=20). Baseline assessment of apnea/hypopnea index (AHI), oxygen saturation in blood, percentage of rapid eye movement, electroencephalogram, electrocardiogram, oro-nasal airflow via a pressure transducer, and Epworth Sleepiness Scale will be done. Then both study group participants will receive their respective appliances. And after one month and three months of delivery of the appliance, all the parameters, i.e., AHI, oxygen saturation in blood, percentage of rapid eye movement, electroencephalogram, electrocardiogram, oro-nasal airflow via a pressure transducer, and Epworth Sleepiness Scale will be re-evaluated and compared with the baseline measurements. Descriptive and analytical statistics will be done. SPSS (Statistical Package for Social Sciences) Version 20.1 will be used as statistical software. The statistical significance between the two groups after one month and three months will be evaluated at p< 0.05.

Discussion

We expect, customized maxillary oral appliance to be more efficient in managing moderate OSA, in comparison with MAD. If the hypothesis of the present study is confirmed, then this customized maxillary appliance will be quoted as a “gold standard” for managing moderate OSA.

Factors Affecting Automatic Positive Airway Pressure Therapy Adherence in Patients Who had Completed the 3-Month Compliance Assessment for Korean National Health Insurance Coverage

Background and Objective The numbers of prescriptions for continuous positive airway pressure and automatic positive airway pressure (APAP) machines have increased dramatically since the Korean government changed national health insurance coverage. This study examined adherence to APAP therapy in patients with obstructive sleep apnea who completed the 3-month adaptation period required by the insurance service, and evaluated the factors predictive of good adherence.Methods We retrospectively reviewed the medical records of a total of 315 patients who received APAP prescriptions between July 2018 and December 2019. After screening, 189 patients were analyzed. Patients were divided into an adherent (AD) group and a non-adherent (NAD) group based on 9 months’ APAP adherence. Patient demographics, medical history, body mass index and pretreatment polysomnography results, as well as APAP therapy adherence-related variables, the 90th percentile pressure, residual apnea hypopnea status, and type of devices or managers were compared between the two groups.Results We found mean usage times, mean pressures, days with ≥ 4 hours of use a day, and 90th percentile pressures differed significantly between the AD and NAD groups. The device-related data at months 1 and 3 and 9 were similar. One type of device performed differently compared to the other devices, but this did not affect adherence.Conclusions The mean pressure and 90th percentile pressure were the main determinants of adherence in patients who passed a 3-month compliance assessment conducted by the Korean National Institute of Health. The data on adherence at months 1, 3 and 9 were similar.

A latent-class heteroskedastic hurdle trajectory model: patterns of adherence in obstructive sleep apnea patients on CPAP therapy

BACKGROUND

Sleep apnea patients on CPAP therapy exhibit differences in how they adhere to the therapy. Previous studies have demonstrated the benefit of describing adherence in terms of discernible longitudinal patterns. However, these analyses have been done on a limited number of patients, and did not properly represent the temporal characteristics and heterogeneity of adherence.

METHODS

We illustrate the potential of identifying patterns of adherence with a latent-class heteroskedastic hurdle trajectory approach using generalized additive modeling. The model represents the adherence trajectories on three aspects over time: the daily hurdle of using the therapy, the daily time spent on therapy, and the day-to-day variability. The combination of these three characteristics has not been studied before.

RESULTS

Applying the proposed model to a dataset of 10,000 patients in their first three months of therapy resulted in nine adherence groups, among which 49% of patients exhibited a change in adherence over time. The identified group trajectories revealed a non-linear association between the change in the daily hurdle of using the therapy, and the average time on therapy. The largest difference between groups was observed in the patient motivation score. The adherence patterns were also associated with different levels of high residual AHI, and day-to-day variability in leakage.

CONCLUSION

The inclusion of the hurdle model and the heteroskedastic model into the mixture model enabled the discovery of additional adherence patterns, and a more descriptive representation of patient behavior over time. Therapy adherence was mostly affected by a lack of attempts over time, suggesting that encouraging these patients to attempt therapy on a daily basis, irrespective of the number of hours used, could drive adherence. We believe the methodology is applicable to other domains of therapy or medication adherence.

Machine learning-based prediction of adherence to continuous positive airway pressure (CPAP) in obstructive sleep apnea (OSA)

Continuous positive airway pressure (CPAP) is the "gold-standard" therapy for obstructive sleep apnea (OSA), but the main problem is the poor adherence. Therefore, we have searched for the causes of poor adherence to CPAP therapy by applying predictive machine learning (ML) methods. The study was conducted on OSAs in nighttime therapy with CPAP. An outpatient follow-up was planned at 3, 6, 12 months. We collected several parameters at the baseline visit and after dividing all patients into two groups (Adherent and Non-adherent) according to therapy adherence, we compared them. Statistical differences between the two groups were not found according to baseline characteristics, except gender (P< .01). Therefore, we applied ML to predict CPAP adherence, and these predictive models showed an accuracy and sensitivity of 68.6% and an AUC (area under the curve) of 72.9% through the SVM (support vector machine) classification method. The identification of factors predictive of long-term CPAP adherence is complex, but our proof of concept seems to demonstrate the utility of ML to identify subjects poorly adherent to therapy. Therefore, application of these models to larger samples could aid in the careful identification of these subjects and result in important savings in healthcare spending.

Partner perceptions are associated with objective sensor-measured adherence to oral appliance therapy in obstructive sleep apnea

The aims of the present prospective clinical study were to determine objective, sensor-measured adherence to a mandibular advancement device (MAD) in patients with obstructive sleep apnea (OSA) and to identify partner-specific adherence-related factors. A total of 77 eligible participants with mild, moderate, or severe OSA and who were non-adherent to continuous positive airway pressure (mean age 56.2 years) participated in the study (32.5% women). The mean (range) observation time between MAD delivery and final follow-up was 8.3 (3.4-16.5) months. The mean apnea-hypopnea index (AHI) was 26.6 events/hr at baseline and 12.5 events/hr at the 8-month follow-up (both p < 0.001). The mean sensor-measured adherence at the 8-month follow-up was 60.1% for ≥4 hr/night of appliance use for ≥5 days/week. Average usage was 6.4 hr/night, when worn. The mean reduction in the AHI was significantly greater in the "good adherence" (Δ 17.4) than the "poor adherence" group (Δ11.0; p < 0.05). From the partner's perspective, the appliance had a positive effect on sharing a bedroom in the good- (55%) compared to the poor-adherence group (25%; p < 0.05) and on their relationship (51.7% versus 17.9%, respectively; p < 0.05). Regression analyses identified the partner's snoring and apneas to be the most significant factor predicting good adherence to MAD (odds ratio 4.4, 95% confidence interval 1.4-14.0). In conclusion, social factors, like partner perceptions, were positively associated with adherence, which indicate that partner's attitudes and support may be a resource that can be utilised to improve adherence in oral appliance treatment of OSA.

Short-Term Effects of a Multidisciplinary Residential Rehabilitation Program on Perceived Risks, Confidence Toward Continuous Positive Airway Pressure Treatment, and Self-Efficacy in a Sample of Individuals Affected by Obstructive Sleep Apnea Syndrome

Continuous positive airway pressure (CPAP) therapy is the standard treatment for obstructive sleep apnea (OSA) syndrome. However, optimizing adherence to CPAP therapy of individuals remains very challenging for clinicians because of the role played by the psychological components. In this study, we verified the changes in cognitions and beliefs of individuals after a four-week multidisciplinary residential rehabilitation program targeting the adaptation to CPAP therapy for OSA syndrome. We assessed the components of perceived risks, confidence toward the treatment, and self-efficacy through the self-report questionnaire, namely the Self-Efficacy Measure for Sleep Apnea (SEMSA) questionnaire. We also explored the role played by the temperamental traits on the changes registered in these components after the treatment. Forty-five participants completed the rehabilitation program, showing a higher level of adherence to the treatment. Significant changes were observed in terms of confidence toward the treatment, although no change was reported in terms of perceived risks and self-efficacy. Moreover, those individuals with a higher persistent temperamental trait reported a significant improvement in perceived risks, in the absence of other significant results. After the rehabilitation treatment, our participants were more prone to consider the effect of CPAP treatment on health outcomes. This was in line with the educational aim of the rehabilitation treatment. The temperament seemed to play only a marginal role in the global changes reported by our participants. We discussed the need for behavioral interventions, in addition to education, in improving self-efficacy.

Improving CPAP Adherence in Adults With Obstructive Sleep Apnea Syndrome: A Scoping Review of Motivational Interventions

Objective: This scoping review aims to provide an accessible summary of available evidence on the efficacy of motivational interventions to increase adherence to Continuous Positive Airway Pressure (CPAP) among patients with Obstructive Sleep Apnea Syndrome (OSAS) and of their specific aspects and strategies by assessing adherence measures. Methods: A literature search was performed in PubMed, Scopus, Medline, PsycINFO, and Web of Science databases using the concepts of "obstructive sleep apnea syndrome," "continuous positive airway pressure," "motivational intervention," and "adherence." Rigorous inclusion criteria and screening by at least two reviewers were applied. Data were extracted to address the review aims and were presented as a narrative synthesis. Results: Search for databases produced 11 randomized controlled trials, all including naïve CPAP users. Findings showed that motivational interventions were more effective than usual care and educational programs in increasing adherence to CPAP, despite results were not always maintained over time across studies. Discussion: To our knowledge, this is the first scoping review of the literature aimed to explore the characteristics and impact of motivational interventions to promote adherence to CPAP in patients with OSAS. More research providing a detailed description of motivational strategies, and testing of their association with positive treatment outcomes via both direct and indirect measures are needed to increase awareness on active mechanisms of change.

Risk-seeking attitude in health and safety domain is associated with continuous positive airway pressure discontinuation in patients with obstructive sleep apnea-a multicenter prospective cohort study

STUDY OBJECTIVES

Many studies have already looked at factors that may influence adherence to continuous positive airway pressure (CPAP) (severity of obstructive sleep apnea (OSA), patients' age, technical aspects, socioeconomic factors, living conditions, psychological factors). Although it has been shown that individuals' preference for risky behaviors in daily life can influence the use of care or adherence to drug therapies in care settings, this has never been tested in OSA. This study aims to analyze the association between risk attitude in the health/safety domain and CPAP discontinuation in a cohort of OSA patients.

METHODS

In a prospective multicenter cohort study nested within the IRSR sleep cohort, consecutive patients who were prescribed CPAP were monitored for at least 6 months. In addition to the data usually collected in the IRSR sleep cohort at baseline, patients also completed a risk-taking questionnaire using the Domain-Specific Risk-Taking (DOSPERT) scale. Cox's proportional hazards regression was used to model the risk of CPAP discontinuation as a function of a linear combination of variables hypothetically related to this risk including health risk attitude.

RESULTS

Of the 489 patients under CPAP, 12.1% (n = 59) were risk-seeking, 87.9% (n = 430) were risk-neutral, and none were risk-averse. Cox's model indicated that a risk-seeking attitude (p = 0.04) and an AHI <30 (p < 0.01) were significantly associated with CPAP discontinuation.

CONCLUSIONS

Patients with risk-seeking behaviors in daily life have been shown to be more likely to discontinue CPAP. The DOSPERT scale can be a useful tool for screening this specific group of patients in clinical practice.

MEntA Program Based on Motivational Interview to Improve Adherence to Treatment of Obstructive Sleep Apnea With Continuous Positive Airway Pressure (CPAP): A Randomized Controlled Trial

Introduction

The first-line treatment for obstructive sleep apnoea is (OSA) continuous positive airway pressure (CPAP) therapy, which achieves a high level of efficacy with continuous use. However, daily application of this therapy requires a motivated patient profile, as lack of adherence is the main problem with this therapy. The aim of this study was to determine whether an educational and training program based on motivational interviewing and proper feedback, improved adherence.

Methods

A randomized, controlled, single-center trial design was performed. The interventions were standard of care vs MEntA Program based on motivational interview for adherence. The main outcome was the adherence with the CPAP therapy after 90 days of treatment. Secondary outcomes were the motivation, perceived competence, quality of life, sleepiness, emotional state, activities and social relations.

Results

For adherence, statistically significant results were obtained in favor of the interventional arm with the MEntA (p < 0.01), with a mean difference of 1.60 h (95% CI, 0.60 to 2.61). The Questionnaire of Evaluation of Perceived Competence in Adherence to CPAP in OSA show also a statistically significant change in favor of the MEntA intervention with a mean difference of 4.61 (95% CI, 3.49 to 5.72) (p < 0.001), as well as quality of life p < 0.001.

Conclusions

The MEntA intervention included as part of an educational and training program for patients with OSA with CPAP therapy shows solid results in terms of its efficacy.

The Impact of Device Modifications and Pressure Delivery on Adherence

This article reviews the evidence to date examining whether adherence to positive airway pressure (PAP) therapy is affected by any device modifications to pressure delivery. To date there is no robust evidence from systematic reviews and meta-analyses indicating that any modification to standard fixed-pressure PAP makes a clinically significant difference to patient adherence to therapy. The main modifications are reviewed in this article and whether improving pressure could drive adherence, in turn improving patient outcomes, is discussed.

Self-Quantification Systems to Support Physical Activity: From Theory to Implementation Principles

Since the emergence of the quantified self movement, users aim at health behavior change, but only those who are sufficiently motivated and competent with the tools will succeed. Our literature review shows that theoretical models for quantified self exist but they are too abstract to guide the design of effective user support systems. Here, we propose principles linking theory and implementation to arrive at a hierarchical model for an adaptable and personalized self-quantification system for physical activity support. We show that such a modeling approach should include a multi-factors user model (activity, context, personality, motivation), a hierarchy of multiple time scales (week, day, hour), and a multi-criteria decision analysis (user activity preference, user measured activity, external parameters). This theoretical groundwork, which should facilitate the design of more effective solutions, has now to be validated by further empirical research.

Tailored Approach to Sleep Health Education (TASHE): a randomized controlled trial of a web-based application

STUDY OBJECTIVES

In a randomized controlled trial, we compared the effect of the Tailored Approach to Sleep Health Education (TASHE) on obstructive sleep apnea (OSA) self-efficacy among community-dwelling blacks in New York City.

METHODS

Study participants were 194 blacks at high risk for OSA based on the Apnea Risk Evaluation System. TASHE intervention was delivered via a Wi-Fi-enabled tablet, programmed to provide online access to culturally and linguistically tailored information designed to address unique barriers to OSA care among blacks. Blacks in the attention-controlled arm received standard sleep information via the National Sleep Foundation website. Blacks in both arms accessed online sleep information for 2 months. Outcomes (OSA health literacy, self-efficacy, knowledge and beliefs, and sleep hygiene) were assessed at baseline, at 2 months, and at 6 months.

RESULTS

We compared outcomes in both arms based on intention-to-treat analysis using adjusted Generalized Linear Mixed Modeling. TASHE exposure significantly increased OSA self-efficacy (OSA outcome expectation [β = .5; 95% CI: .1-.9] and OSA treatment efficacy [β = 0.4; 95% CI: .0-.8]) at 2 months but not at 6 months. Additionally, TASHE exposure improved sleep hygiene at 6 months (β = 6.7; 95% CI: 2.2-11.3) but not at 2 months.

CONCLUSIONS

Community-dwelling blacks exposed to TASHE materials reported increased OSA self-efficacy compared with standard sleep health education. Stakeholder-engaged, theory-based approaches, as demonstrated in the TASHE intervention, can be used successfully to deliver effective sleep health messages.
