Perceived sleep problems after spinal cord injury: Results from a community-based survey in Switzerland

Adherence to continuous positive airway pressure therapy in patients with spinal cord injury and obstructive sleep apnea: trajectories and predictors

PURPOSE

To identify specific determinants of non-adherence or cessation of continuous positive airway pressure (CPAP) therapy in a population of patients with spinal cord injuries (SCI).

METHODS

Retrospective analysis of data from patients with SCI who underwent a full night supervised polysomnography between 2015 and 2021 and presented with moderate to severe obstructive sleep apnea (OSA) and for whom CPAP was indicated. Adherence was studied at 1, 6, and 12 months. Univariate and multivariate analyses were performed to identify factors associated with non-adherence (< 4 h per night or CPAP cessation). Factors studied were demographic and disease-related data and both subjective and objective sleep parameters.

RESULTS

A total of 60 patients were included (40% cervical SCI). In univariate analysis, the only predictive parameters of non-adherence observed at 1, 6, and 12 months were the average use of CPAP on the 1st night (p = 0.02) and over the 1st week (p ≤ 0.001). A complete lesion (AIS-A) was predictive of non-adherence at 1 and 6 months (p = 0.02 at 6 months), while mask leakage was associated with non-adherence at 12 months (p = 0.02). Upper limb autonomy and the presence of family caregivers did not appear to be protective. In multivariate analysis, only the average use in the first week remained predictive of adherence (> 4 h) in the short, medium and long term.

CONCLUSION

In patients with SCI and OSA, the 1st week of CPAP treatment seems to be determinant of short-, medium-, and long-term CPAP adherence. Support for SCI patients from the start of treatment is essential and may help avoid treatment failures.

The impact of sleep quality on health, participation and employment outcomes in people with spinal cord injury: Analyses from a large cross-sectional survey

BACKGROUND

Poor sleep is common in people with spinal cord injury (SCI), yet little is known about its impact on employment and participation outcomes.

OBJECTIVES

This study aimed to (1) describe the sleep quality of a large sample of Australians with SCI and compare the results to data from an adult control and other clinical populations; (2) examine associations between sleep quality and participant characteristics; and (3) explore the relationship between sleep and outcomes.

METHODS

Cross-sectional data from the Australian arm of the International Spinal Cord Injury (Aus-InSCI) survey from 1579 community-dwelling people aged >18 years with SCI were analysed. Sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI). Relationships between participant characteristics, sleep quality and other outcomes were examined with linear and logistic regression.

RESULTS

The PSQI was completed by 1172 individuals; 68% reported poor sleep (global PSQI score >5). Subjective sleep quality in people with SCI was poor (mean PSQI = 8.5, SD 4.5) when compared to adults without SCI (PSQI = 5.00, SD 3.37) and with traumatic brain injury (PSQI = 5.54, SD 3.94). Financial hardship and problems with secondary health conditions were significantly associated with worse sleep quality (p < 0.05). Poor sleep quality was strongly associated with lower emotional wellbeing and energy, and greater problems with participation (p < 0.001). Individuals engaged in paid work reported better sleep quality (mean PSQI = 8.1, SD 4.3) than unemployed individuals (mean PSQI = 8.7, SD 4.6; p < 0.05). Following adjustment for age, pre-injury employment, injury severity and years of education, better sleep quality remained strongly associated with being employed (OR 0.95, 95% CI 0.92 to 0.98; p = 0.003).

CONCLUSIONS

This study demonstrated pervasive and impactful relationships between sleep quality and important SCI outcomes. Poor sleep quality was strongly associated with worse emotional wellbeing and vitality, unemployment and lower participation. Future studies should aim to determine whether treating sleep problems can improve outcomes for people living with SCI.

Which factors have an association to the Quality of Life (QoL) of people with acquired Spinal Cord Injury (SCI)? A cross-sectional explorative observational study

STUDY DESIGN

Cross-sectional explorative observational study.

OBJECTIVES

To identify factors which have an association to the self-perceived Quality of Life (QoL) for persons with acquired spinal cord injury (SCI).

SETTING

Eight specialized SCI-centers in Germany. The GerSCI survey is the German part of the International Spinal Cord Injury Survey (InSCI).

METHODS

Self-disclosure questionnaire, created from the InSCI group, translated and adapted for Germany. The questionnaire collects a very broad range of data and, and due to its design as a self-report, is particularly suitable for the analysis on QoL. Because of the content, which is binding for all participating states, it allows a direct comparability of the results. Included in Germany were 1479 persons with acquired SCI aged 18 years and older.

RESULTS

Various factors were identified with high associations to QoL, including changeable and unchangeable ones, such as those of particular importance: pain, sleep problems, sexual dysfunction, age, and time since onset of SCI. Some results confirmed reports of previous studies, others were surprising.

CONCLUSION

this study provides an important basis for the planned analysis of the InSCI participating countries in the 6 WHO regions. Germany was able to contribute the largest study population. The concrete study design of InSCI allows us to directly compare data and helps us to improve ourselves within the framework of a "learning health system". Medical measures can be orientated towards the found results, in order to ensure the best possible care and support by the therapeutic team, individually adapted to the person, place of residence and impairment.

Association between sleep quality and participation in people with spinal cord injury: A preliminary study

OBJECTIVE

To explore the association between perceived sleep quality and participation in people with spinal cord injury (SCI).

DESIGN

Cross-sectional study.

SETTING

Spinal unit at the Città della Salute e della Scienza University Hospital of Turin, Italy.

PARTICIPANTS

From May to July 2019, 55 consecutive outpatients were recruited.

OUTCOME MEASURES

A set of structured questionnaires was administered. It included sociodemographic data, the Pittsburgh Sleep Quality Index, the Utrecht Scale for Evaluation of Rehabilitation-Participation, the Spinal Cord Independence Measure Self-Report, the Short Form version 12.2, and the Hospital Anxiety and Depression Scale. T-tests were used to highlight differences between participation and participant characteristics. Bivariate analyses and linear regressions were performed to identify associations between sleep quality and participation.

RESULTS

Differences in participation occurred mainly in individuals with a higher level of injury, caregiver dependency, and lower functional level. Participants reporting better sleep quality had more frequent (r = -0.36, P < 0.01), less restricted (r = -0.32, P < 0.05), and more satisfactory participation (r = -0.33, P < 0.01). Linear regression analyses showed that poor sleep quality was significantly associated with reduced participation frequency (β = -0.30, P = 0.03) and less satisfaction with participation (β = -0.49, P < 0.001). Moreover, age, number of hours slept at night, and time since injury were associated with satisfaction with participation.

CONCLUSIONS

An association was found between sleep quality and participation in people with SCI. Given the high prevalence of sleep problems and their association with all dimensions of participation, the promotion of sleep quality should be encouraged because it may positively affect participation.
