Sleep habits and sleep complaints in Austria: current self-reported data on sleep behaviour, sleep disturbances and their treatment.

OBJECTIVES: To acquire current information on sleep habits, disturbances and treatment options in the adult population of Austria and compare results with previously collected data. MATERIALS AND METHODS: A representative sample of the Austrian population (women: n = 522, men: n = 478). RESULTS: Seventy-five percent reported daily sleep-duration between 6 and 8 h. In 76%, sleep latency was <30 min, 15% described difficulties in sleep maintenance. Longer sleep on weekends was prevalent in 54%, 23% took a nap. Concerning sleep environment, 31% reported sleeping alone; the rest had a constant or occasional bed partner. Sleep disturbances such as sleep disruption or prolonged sleep latency were reported by 18%. Predominant symptoms included snoring/apneas (22%), nightmares (22%) and restless legs (21%). Daytime tiredness was reported by 17% and sleepiness by 20%. Twenty-four percent did not take treatment. Only 7% asked for medical help: 96% consulted their physician; 47% tried to change their way of living. Sleep promoting drugs were taken by 7%. Sleep improving measures were: sleep promoters (45%), general measures (20%), consultation of general practitioner (20%), psychotherapy (6%), and technical tools (3%). Comparison with a dataset of 1993 revealed only a slight increase in short sleepers and a slight decrease in long sleepers. CONCLUSIONS: Subjectively reported sleep disorders proved to be relatively stable between 1993 and 2007.

[Statement of the Austrian Society of Pneumology (ASP)]. / Stellungnahme der Österreichischen Gesellschaft für Pneumologie (ÖGP): Management von Patienten mit SARS-CoV-2-Infektionen und von Patienten mit chronischen Lungenerkrankungen während der COVID-19-Pandemie (Stand 27.04.2020).

The COVID-19 pandemic is currently a challenge worldwide. In Austria, a crisis within the health care system has so far been avoided. The treatment of patients with community-acquired pneumonia (CAP), including SARS-CoV­2 infections, should continue to be based on evidence-based CAP guidelines during the pandemic. However, COVID-19-specific adjustments are useful. The treatment of patients with chronic lung diseases must be adapted during the pandemic, but must still be guaranteed.

Sleeping habits in the Austrian population.

OBJECTIVES: To gain reliable data on sleeping habits and sleep disturbances of the Austrian population. BACKGROUND: Exact data on sleeping habits are of interest in relation to assessment of sleep disturbance-related illnesses and general social processes. METHODS: A prospective, cross-sectional study was performed with recruitment of a representative sample of 1049 Austrians (aged 15-82 years), according to the Federal Statistics population characteristics. Interviews were conducted in the households of the participants by specially trained interviewers of an institute for empirical research. RESULTS: Men consider their quality of sleep to be significantly better than women (P=0.00234), and younger persons consider their quality of sleep to be significantly better than older persons (P=0.00001). In comparison, women and people over the age of 50 report worse subjective sleep quality, worse sleep efficiency, more difficulty in falling asleep and sleep maintenance, more apneic events, more pathologic limb movements, more daytime dysfunction, and more intake of sleeping medication. Other sociodemographic factors influence sleep reports to a lesser extent. CONCLUSIONS: Subjectively disturbed sleep (prevalence in the total population 24.9%), excessive hypnotic drug intake (prevalence 13.0%), and daytime dysfunction (prevalence 17.4%) are a widespread problem, especially in women and older people. With increasing life expectancy in Western societies, the prevalence of sleep disturbances will increase.

N-CPAP rejecters--a specific group of noncompliant patients with obstructive sleep apnea syndrome.

A large number of studies have been focused on patients with severe obstructive sleep apnea syndrome (OSAS) being non-compliant with N-CPAP therapy, but data concerning patients who reject N-CPAP therapy from the very start, without a day of N-CPAP home therapy, do not exist. The purpose of the study was to determine differences, if any, in the quality of life (QoL) between patients rejecting N-CPAP therapy from the start, untreated patients with severe OSAS waiting for N-CPAP titration, and controls. Qol was measured in terms of life satisfaction on the basis of the Munich life quality dimension list (MLDL), an instrument for cognitive assessment of elementary components (physical condition, psyche, social life, everyday life) of QoL. Untreated patients (n = 16) with severe OSAS have a significantly worse QoL in the dimension of psyche (p = 0.00022), social life (p = 0.00582) and everyday life (p = 0.01633) than do rejecters of therapy (n = 19). In the dimension of physical condition, no significant difference was seen (p = 0.47138). Compared with controls (n = 113), rejecters of therapy have a significantly lower QoL score in regard of physical condition (p = 0.00014) but not in terms of psyche, social life and everyday life. We conclude that a good QoL and the absence of the stress of suffering is one reason why patients with severe OSAS reject N-CPAP therapy in spite of physical impairment.

[Epidemiology of sleep disorders in Austria]. / Zur Epidemiologie von Schlafstörungen in Osterreich.

UNLABELLED: Epidemiologic data on sleep disturbances in Austria were collected for the first time in March/April 1993 in a representative inquiry ( SAMPLE: n = 1000, 471 males, 529 females). 26% of the subjects reported sleep disturbances which were mostly chronic (21% had suffered from sleep disturbance for more than one year). The incidence of sleep disturbances increased with age, namely 13% in 14-30 year-old subjects, 22% in 31-50 year-old ones and 41% in subjects over 50. 7% suffered from disturbances in sleep initiation, i.e., they had a sleep latency of over 30 minutes. 19% of them had difficulties in getting to sleep at least once a week. Disturbances in maintaining sleep were reported by 28% of subjects, 56% of them needing longer than one hour to get back to sleep. 30% suffered from daytime sleepiness, 43% of the subjects were impaired by their sleep disturbances in some way, but only 34% had consulted their doctor.

Effects of socio-demographic variables on health-related quality of life determined by the quality of life index--German version.

STUDY OBJECTIVE: The purpose of this study was to determine subjective health-related quality of life (HRQoL) in a sample of the Austrian population over 14 years of age in order to evaluate the effect of socio-demographic variables on HRQoL. DESIGN/SETTING: HRQoL was determined by means of the quality of life index-German version (QLI-Ge). The influence of socio-demographic variables on HRQoL was assessed by statistical analysis using the Kruskal-Wallis test and an analysis of variance. PARTICIPANTS: A random-quota procedure was used to get balanced representation from regions and demographic groups of the Austrian population. The sample consisted of 1049 participants, 493 men and 556 women. MAIN RESULTS: Age was found to influence the QLI-Ge total score (index score) and most individual items, with increasing age resulting in a decrease in HRQoL. Differences between the sexes were observed in three dimensions: males scored higher in 'physical well-being', 'psychological well-being' and 'occupational functioning'. Marital status impacted most items with married persons showing better values than divorced persons or singles. Profession had only a minor effect on HRQoL, the level of education showed no influence at all. CONCLUSIONS: The socio-demographic variables age, sex and objective living conditions had a major influence on subjectively rated HRQoL, whereas profession and education were found to play a minor role in this context. It is recommended that in the interpretation of studies assessing HRQoL the above-mentioned objective factors be considered. This will be of particular importance when determining the effect of a pharmacotherapy on HRQoL in patients.

[Hospital-acquired pneumonia]. / Im Krankenhaus erworbene Pneumonien.

Nosocomial pneumonia is sometimes preventable. In manifestation it is a challenge to the interdisciplinary cooperation to pneumologists, internal medicine, intensive care medicine, clinical microbiologists, nursing staff and physiotherapists. Preventive measurements are of special value.

[Diagnostic process of alveolitis--state of the art]. / Diagnosegang der Alveolitis--Stand des Wissens.

Diagnosing of alveolitis is a puzzle of many pieces, based on clinical experience and keeping in mind the criteria of extrinsic allergic alveolitis. They are antigen-exposure, typical delayed postexpositional symptoms (cough, chills, fever, dyspnea, tiredness), and serological tests of precipitating antibodies. Helpful findings are X-ray of the chest, high resolution computer tomography, auscultation findings, lowered diffusing capacity, bronchoalveolar lavage with lymphocytes > 50% and low T4/T8-ratio, histology of periphere lung specimens, and occasional inhaled provocation. Differential diagnosis are toxic lung disorders, drug adverse effects, sarcoidosis, silicosis, autoimmune alveolitis, idiopathic fibrosing alveolitis. The most frequent failure in diagnosis are common viral cold, bronchopneumonia, sarcoidosis, chronic bronchitis, and miliar tuberculosis.

[Sleep apnea and the work site]. / Schlafapnoe und Arbeitsplatz.

The sleep apnoea syndrome (SAS) is characterised by somatic, in particular cardiopulmonary and psychosocial, symptoms, the latter severely impairing the patient's social life. Excessive daytime somnolence and the resulting problems severely stress patients with SAS. Among 24 patients with SAS, 79.2% stated that they fell asleep during the day, frequently in 41.8% and occasionally in 37.4%. In addition, 70.8% of the patients with SA did not feel adequately rested on waking in the morning. Of the 24 patients, 17 had a job, and 11 of these experienced difficulty staying awake at the workplace. Suitable timely treatment (for example, with n-CPAP) improves not only the somatic, but also the neuropsychological symptoms.

[Comparative computerized tomography cephalometric and pharyngometric studies of patients with severe and mild sleep apnea, and in a control group]. / Vergleichende computertomographische kephalometrische und pharyngometrische Untersuchungen bei Patienten mit schwerer und leichter Schlafapnoe, sowie einer Kontrollgruppe.

116 males were examined. Of these, 52 belonged to a control group, whereas 40 had severe obstructive sleep apnoea (apnoea index > 20 + clinical symptoms) and 24 mild obstructive sleep apnoea (apnoea index 5-20 + clinical symptoms) (in the following, OSA signifies obstructive sleep apnoea). Cephalometry and planimetric examinations of the pharynx were performed in recumbent position with the head in neutral position and with shallow respiration. The narrowest passage of the pharynx was measured; other measured sites were the areas of the nasopharynx, oropharynx (at the level of the tip of the palatine uvula) and of the hypopharynx (at the level of the base of the tongue). The sum of all the measured cross-sections was obtained. The cephalogram was evaluated to obtain the length and thickness of the soft palate, the distance between the mandible and hyoid bone, the posterior airspace (PAS), the nuchal subcutaneous fatty tissue at the level of the spine of the second cervical vertebra (also known as axis), the thickness of the posterior pharyngeal wall at the level of the second cervical vertebra, or axis, and the angles between the sella, nasion and superior maxilla and between the sella, nasion and mandible (SNA and SNB, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

Impact of nasal continuous positive airway pressure treatment on quality of life in patients with obstructive sleep apnoea.

Quality-of-life (QoL) issues have become increasingly important in health care practice and research. Obstructive sleep apnoea syndrome (OSAS) results in an especially serious reduction in QoL. The purpose of this study was to measure the QoL (life satisfaction) of OSAS patients treated with nasal continuous positive airway pressure (nCPAP). We aimed to determine whether and to what extent the QoL of OSAS patients using nCPAP differs from that of randomly selected subjects without this disorder. The QoL of 67 patients treated for at least 3 months with nCPAP, 21 OSAS patients at the time of OSAS diagnosis, and 113 randomly selected persons visiting the hospital (controls) was investigated with the help of the Munich life-quality dimension list (MLDL), an instrument for cognitive assessment of elementary components (physical condition, psyche, social life, everyday life) of QoL. It was found that QoL of OSAS patients treated with nCPAP did not significantly differ from that of control subjects with regard to elementary components. The 21 untreated OSAS patients showed significantly lower scores in all four subcategories: physical condition (p<0.0005), psyche (p<0.01), social life (p<0.0005) and everyday life (p<0.007). Thus, it may be concluded that nasal continuous positive airway pressure therapy has an important impact on the quality of life of obstructive sleep apnoea syndrome patients, and signifies a further advantage in addition to clinical aspects. Treated patients are as satisfied or dissatisfied with their life as persons without this illness.

[Sleep apnea as a risk factor]. / Die Schlafapnoe als Risikofaktor.

Sleep apnea and snoring are widely discussed as risk factors for internal and neurological diseases. The prevalence of snoring in an Austrian population survey is about 27.2% (males 36.5%, females 18.9%), and that of apnea (respectively irregularity and/or cessation of breathing) about 8.5% (31% of all snorers). Clinical symptoms like naps, daytime sleepiness, unquiet sleep, hypertonia, headache in the morning and psychological symptoms may be characteristics of sleep apnea. They should lead to further diagnosis and removal of this risk factor for ischemic heart disease and stroke.

Sleep and quality of life in the Austrian population.

PURPOSE: To compare the self-reported estimation of sleep quality evaluated by the Pittsburgh Sleep Quality Index (PSQI) and life quality assessed by the Quality of Life Index (QLI). BACKGROUND: The PSQI comprised 19 questions and assessed a wide variety of factors relating to sleep quality. The QLI consisted of 10 items for self assessment of different dimensions of life quality. SUBJECTS: A representative Austrian sample (n = 1049) aged above 15 years. PROCEDURE: Interviews in the homes of the participants. RESULTS: 32.1% could be classified as poor sleepers (37% females, 26.5% males). Sleep quality decreased with increasing age, especially in women. Overall quality of life was highest in younger (15-29 years) and lowest in elderly subjects (over 50 years). Life quality decreased with increasing age. Between subjective sleep quality and quality of life a moderate, significant correlation was found (r2= 0.6721). CONCLUSIONS: Complaints about a bad quality of sleep could be used as a screening method in the exploration of patients' quality of life (QoL).
