Reliability and validity of a Norwegian version of the Epworth sleepiness scale.

Objective: The objective of this study was to assess the reliability and validity of a Norwegian version of the self-administered Epworth sleepiness scale (ESS).

Materials And Methods: Two samples responded to the ESS: (1) 226 patients previously evaluated for obstructive sleep apnea, of whom 51 also responded to a retest 2 weeks later, and (2) 37 ambulant patients complaining of excessive daytime sleepiness, who were referred to multiple sleep latency testing (MSLT). We assessed internal consistency reliability with Cronbach's alpha and test-retest reliability with weighted kappa (Kw) or an intraclass correlation coefficient (ICC).

Predictors of symptoms of anxiety and depression in obstructive sleep apnea.

Background And Purpose: To assess factors associated with anxiety and depression in patients with obstructive sleep apnea syndrome (OSAS).

Patients And Methods: The study was comprised of a postal survey with a hospital chart review. Questionnaires were mailed to 242 previously hospitalised patients with OSAS.

Reliability and validity of the Norwegian version of the Functional Outcomes of Sleep Questionnaire.

The aim of this study was to validate the Norwegian version of a self-administered 30-item quality of life questionnaire designed to assess disorders of excessive sleepiness, the Functional Outcomes of Sleep Questionnaire (FOSQ). In total 226 patients previously evaluated for obstructive sleep apnea were included in the study. The patients received a postal questionnaire with the FOSQ, the Short Form 36 (SF-36) questionnaire, and a scale for assessment of excessive daytime sleepiness, the Epworth sleepiness scale (ESS).

[Coding of diagnoses in chronic obstructive pulmonary disease--economic consequences].

Background: We wanted to assess the quality of coding of diagnoses and procedures, the resulting DRG classification and the financial consequences of coding errors for the hospital owner in patients with chronic obstructive pulmonary disease.

Material And Methods: We identified 330 hospitalizations in the Central Hospital of Akershus 1 January to 30 November 1999 in DRG 088 (chronic obstructive pulmonary diseases) after an initial DRG classification. The patients' discharge summaries were reviewed for errors in coding of diagnoses and procedures and, where applicable, recoded.

[Prognosis of inoperable non-small cell bronchial cancer].

The article describes a retrospective study of the prognosis for 450 patients with inoperable non-small cell lung cancer discharged during the period 1970 to 1979. 81% of the patients were males. The predominant cell type was squamous cell carcinoma.
