(2009)Anticholinergic medicines are commonly used to treat e.g. incontinence. These medicines have side effects, which may cause and also exacerbate e.g. dryness of the mouth, increased heart rate, and even cognitive impairment. Older people may be more at risk for these side effects as they may be experiencing similar symptoms as a natural effect of aging, and because they may be using several medicines causing these effects. Older people often have a high medicine burden and also a high disease burden. Measuring anticholinergic effects to change medicine regimens and to reduce the symptoms is difficult as there is no golden standard method. This thesis investigated the published methods available for estimating anticholinergic burden in the literature review part, and used one anticholinergic scoring system, the Anticholinergic Risk Scale, in a cross-sectional study to test the effects of anticholinergics on mortality in 1004 older institutionalised patients from Helsinki area public hospitals. Cross-tabulations and Kruskal-Wallis or Chi square methods were used to detect differences between variables such as nutritional status or certain diagnoses when the patients were stratified according to their anticholinergic use. Cox Proportional Hazard regression, the logrank test and Kaplan-Meier curve were used to investigate the effects of anticholinergics on 5-year all-cause mortality. An in vitro serum assay and seven anticholinergic scoring systems were identified in the literature search. Also, 17 anticholinergic lists were identified, which covered 278 medicines, of which 21 appeared on at least eight of the lists. In the empirical study, the women's (n = 745) mean (± SD) age was 83.35 (± 9.99) years, and they were older than the men (n = 241, mean age ± SD 75.11 ± 11.48, p < 0.001). The 1004 patients (response rate 70 %) were using a mean (± SD) number of 7.1 ± 3.4 regular medicines (range 0-20). 455 patients used no anticholinergics, 363 had some anticholinergic burden (score 1 or 2), and 186 had a high burden, with anticholinergic scores of 3 or more. The mean ARS score (± SD) was 1.2 ± 1.5 (range 0-10). When three anticholinergic lists were compared, all three lists identified only 280/791 of patients who were anticholinergic users according to at least one list. No association was found between anticholinergic medicine use and mortality. There are several methods available for measuring anticholinergic burden, but there is a need for a consensus method. This was highlighted by the lack of agreement on medicines on different lists and when three anticholinergic lists tested identified different patients when compared to each other. Anticholinergic use was common in this frail, older patient sample, but no effect on mortality was shown in this study setting. The cross-sectional nature of the data limits the reliability of the study, and any conclusions beyond older patients in Helsinki area must be done very cautiously. Future research should define anticholinergics better and investigate their possible effect on mortality in a prospective, randomised, and controlled setting.

(2014)In Finland the elderly residents of long-term care facilities are often prescribed a lot of medications, especially psychotropic drugs. It also happens that a patient or a resident has to be physically or chemically restrained. Chemical restraining can be defined in many ways, for example as using a drug - usually an antipsychotic - to restrict the freedom or movement of a patient and to control his or her behavior. In nursing homes the staff is in a key position when it comes to deciding on the use of chemical restraining or PRN medication. A legislation to guarantee the self-determination of a patient and to define how physical restraining can be used is now being prepared in Finland. Only a few studies on chemical restraining from a nurses' point of view have been made so far. Thus, the aim of this study is to provide more information on the level of knowledge, the attitudes and perceptions of nurses regarding chemical restraining and the effect of those on deciding whether to use chemical restraints or not. Three focus groups with nurses were conducted in Hyvinkää nursing homes (n=13). The groups were recruited both by e-mail and directly from the wards. The focus group discussions were digitally audiotaped and transcribed verbatim. The content of the transcripts was then analyzed using a constant comparative method. According to the study most of the antipsychotics used in long-term care were used daily. However, it is not uncommon for the nurses to be unsure about their knowledge on the use of medicines. It is thus important to help the nursing staff to increase their knowledge and skills in pharmacology. The nurses also wished to get extra training for treating people with dementia. The concept of chemical restraining is quite ambiguous, and the use of chemical restraints is a complex ethical issue because the reasons for and effects of administering it vary depending on the situation. The study shows that the chemical restraining is most often considered justified when it is used to ensure the safety of a patient, relieve anxiety or to keep the working conditions of the staff tolerable. Also a shortage of manpower and a request by the family can influence the decision on using chemical restraints. The lack of proper common guidelines causes confusion and wide variation in the use of chemical restraints. Many interviewees were hoping for more open discussion and cooperation on using chemical restraining. The nurses also mentioned many alternatives to rely on instead of using chemical restraints, such as soothing, comforting and creating a safe feeling for the patients, daily routines and stimulus. One of the key factors for taking to these instead of chemical restraints are the manpower resources in the facilities. Educating the staff can also help them to find more options for chemical restraining and make staff members recognize new or remember forgotten routines for caring for the patients without using psychotropic drugs.
