- Introduction: Since sleep is found to be a fundamental part in experiencing quality of life and health it is of importance that nurses and other health care personnel strive to improve sleep and prevent sleep disturbances. Insomnia, which is the most common form of sleep disturbances, has also been found to be related with cardiac disorders. Elderly people are especially vulnerable for poor sleep; prevention of sleep disturbances should be of regard when caring for older persons. The Minimal Insomnia Symptom Scale (MISS) is a three item screening instrument previously found to be psychometrically sound and capable of identifying insomnia in the general population (20-64 years). However, its measurement properties have not been studied in an elderly population. Our aim was to test the measurement properties of the MISS among people aged 65+ in Sweden.Methods and materials: Data from a cross-sectional survey of 548 elderly individuals were analyzed in terms of assumptions of summation of items, reliability and optimal cut-off score by means of ROC-curve analysis and compared with self-reported insomnia criteria. The items of MISS describes the major features of insomnia, i.e. difficulties initiating sleep, waking at night and not feeling refreshed by sleep. A total score ranging between 0 and 12 is calculated, where higher scores indicate more severe insomnia.Results: Reliability was found to be 0.81. ROC analysis where MISS was compared with self-reported insomnia criteria (i. e. day-time sleepiness, not feeling refreshed by sleep, experiencing sleep difficulties). Optimal cut-off score was identified as more or equal to 7, and sensitivity 93%, specificity 84%.Conclusions: Data support the measurement properties of MISS as an insomnia screening instrument among elderly persons and its brevity as well as the easy scoring system makes it appealing in clinical practice.

- Background: Insomnia is common among elderly people and associated with poor health. The Minimal Insomnia Symptom Scale (MISS) is a three item screening instrument that has been found to be psychometrically sound and capable of identifying insomnia in the general population (20-64 years). However, its measurement properties have not been studied in an elderly population. Our aim was to test the measurement properties of the MISS among people aged 65 + in Sweden, by replicating the original study in an elderly sample. Methods: Data from a cross-sectional survey of 548 elderly individuals were analysed in terms of assumptions of summation of items, floor/ceiling effects, reliability and optimal cut-off score by means of ROC-curve analysis and compared with self-reported insomnia criteria. Results: Corrected item-total correlations ranged between 0.64-0.70, floor/ceiling effects were 6.6/0.6% and reliability was 0.81. ROC analysis identified the optimal cut-off score as ≥7 (sensitivity, 0.93; specificity, 0.84; positive/negative predictive values, 0.256/0.995). Using this cut-off score, the prevalence of insomnia in the study sample was 21.7% and most frequent among women and the oldest old. Conclusions: Data support the measurement properties of the MISS as a possible insomnia screening instrument for elderly persons. This study make evident that the MISS is useful for identifying elderly people with insomnia-like sleep problems. Further studies are needed to assess its usefulness in identifying clinically defined insomnia.

- Sleep is found to be a fundamental part in experiencing health. Sleep is needed for memory consolidation, metabolic balance, immune functioning and alertness at day time and experiencing quality of life. Insomnia has also been found to be associated with cardiac disorders. Elderly people are especially vulnerable for poor sleep, why prevention of sleep disturbances should be of regard when caring for older persons. MISS is a 3 item questionnaire, with a total-score of 0-12 that could be used to find insomnia in elderly persons. Aim: To test of the measurement properties of the Minimal Insomnia Symptom Scale in an elderly sample ≥65 years in Sweden. Study sample Persons participating in the Swedish National Study on Ageing and Care – Blekinge were invited. ● 548 participated (response-rate 61.4%) ● Mean age 77.8 (SD 8.63) years ● Female 57.5% Results Reliability was found to be 0.81. ROC analysis where MISS was compared with self-reported insomnia criteria (i.e. day-time sleepiness, not feeling refreshed by sleep, experiencing sleep difficulties) identified optimal cut-off score as ≥7, and sensitivity 93%, specificity 84%. Area under curve = 0.93. Conclusion Data support the measurement properties of MISS as an insomnia screening instrument among elderly persons and its brevity makes it appealing. Through insomnia-screening, older persons at risk of health problems can be found and offered treatment and thereby health and quality of life can be restored.

- Thisstudy aimed to describe and identify risk factors associated with hospital-acquired pressure ulcers among adults in an acute care hospital compared with patients with pre-existing pressure ulcers present on admission. A further aim was to identify the preventive measures performed with both groups respectively. Pressure ulcers occur most often in older and immobile persons with severe acute illness and neurological deficits. However, few studies have adressed risk factors that are associated with hospital-acquired pressure ulcers compared with patients with pre-existing pressure ulcers. A point prevalence study with a cross-sectional survey design was conducted at a Swedish university hospital. Data on 535 patients were recorded using a modified version of the protocol developed and tested by the European Pressure Ulcer Advisory Panel, including the Braden scale for risk assessment. The prevalence of pressure ulcers was 27% (95% confidence interval, 23-31%.) Higher age and total Braden score below 17 were significantly associated with the presence of pressure ulcers. Among individual risk factors higher age, limited activity level and friction and shear while seated or lying down were associated with hospital-acquired pressure ulcers, whereas only higher age and friction and shear were associated with the presence of pressure ulcers in the overall sample. There was an overall sparse use of preventive measures to relieve pressure. The findings of the present study revealed that pressure ulcers and the insufficient use of preventive measure to relieve pressure is still a problem in acute care settings. A continued focus must be placed on staff training in identifying patients at risk for pressure ulcers development.

- Background The psychometric properties of the three-item Minimal Insomnia Symptom Scale (MISS) were evaluated using the classical test theory. Different cut-offs for identifying insomnia were suggested in two age groups (≥6 and ≥7 among adult and elderly people, respectively). The aim of the present study was to test the measurement properties of the MISS using the Rasch measurement model, with special emphasis on differential item functioning by gender and age. Methods Cross-sectional MISS data from adult (age 20–64 years, n = 1075) and elderly (age 65+, n = 548) populations were analysed using the Rasch measurement model. Results Data generally met Rasch model requirements and the scale could separate between two distinct groups of people. Differential item functioning was found by age but not gender. The difference between the adult and elderly samples was lower for the originally recommended ≥6 points cut-off (0.09 logits) than for the ≥7 points cut-off (0.23 logits), but greater at the lower and higher ends of the scale. Conclusions This study provides general support for the measurement properties of the MISS. Caution should be exercised in comparing raw MISS scores between age groups, but applying a ≥6 cut-off appears to allow for valid comparisons between adults and the elderly regarding the presence of insomnia. Nevertheless, additional studies are needed to determine the clinically optimal cut-score for identification of insomnia.
