Balance is among the most important prerequisites for safe and independent mobility. Whether musculoskeletal pain is related to standing balance impairment has received limited attention. The aim of this study was to examine the association of musculoskeletal pain with the control of balance in older people.Methods. A total of 605 participants aged 75 years and older (mean age 80.4, 71 % women) were interviewed about presence and severity of musculoskeletal pain. Balance was measured by a force platform, and impaired balance was defined as a high sway velocity moment or inability to maintain semitandem standing.Results. Musculoskeletal pain was reported by 48% of the participants, of whom majority had moderate to severe pain in lower extremities or back. Participants with moderate to severe musculoskeletal pain swayed more while standing than those without pain. After controlling for age, gender, body mass, chronic diseases, muscle strength, and physical activity, the participants with moderate to severe pain had more than twice (odds ratio 2.33, 95% confidence interval 1.44-3.76) the risk for impaired balance compared with those without pain.Conclusions. The findings demonstrate a direct relationship between the moderate to severe musculoskeletal pain and impaired postural balance. Pain seems to be an important target for the prevention of balance impairment and further mobility limitation among older people. © 2010 The Author. Source

Background: The study evaluated the effects of an annual medication assessment conducted as part of a Comprehensive Geriatric Assessment (CGA) on the prevalence of psychotropic drug use in community-dwelling elderly people. Methods: Randomly selected persons (n = 1000) aged ≥75 years living in the city of Kuopio, Finland were randomized to intervention and control groups. The intervention group underwent an annual (2004-2006) medication assessment as part of a CGA by physicians. Data on drug use were gathered by interviews at baseline (2004) and in three following years (2005-2007). Generalized estimating equations (GEE) were applied to explore whether the prevalence of psychotropic drug use differed between the community-dwelling participants of the intervention (n = 361) and control groups (n = 339) over time. Results: At baseline, nearly 40% of the participants used psychotropic drugs in each group. In the intervention group, the study physicians implemented 126 psychotropic drug-related changes, 39% of which were persistent after one year. The prevalence of use of psychotropic drugs, antipsychotics and anxiolytic/hypnotics did not differ between the groups over time. The prevalence of antidepressant use remained constant in the intervention group, but increased in the control group (p-value for interaction = 0.039). The prevalence of concomitant use of psychotropic drugs decreased non-significantly in the intervention group, but increased in the control group (p-value for interaction = 0.009). Conclusions: Conducting an annual medication assessment outside the usual primary health care system does not appear to reduce the prevalence of psychotropic drug use in community-dwelling elderly people. However, it may prevent concomitant use of psychotropic drugs. © 2010 International Psychogeriatric Association. Source

Background: Pain is often underrecognized and undertreated among older people. However, older people may be particularly susceptible to adverse drug reactions linked to prescription and nonprescription analgesics. Objectives: The aims of this study were to assess the prevalence of analgesic use among a random sample of community-dwelling people aged ≥75 years, and to investigate factors associated with daily and as-needed analgesic use. Methods: A random sample of people aged ≥75 years was drawn from the population register in Kuopio, Finland, in November 2003. Data on prescription and nonprescription analgesic use were elicited during nurse interviews conducted once for each participant in 2004. Self-reported drug utilization data were verified against medical records. The interview included items pertaining to sociodemographic factors, living conditions, social contacts, health behavior, and state of health. Physical function was assessed using the Instrumental Activities of Daily Living Scale, and the 10-item Barthel Index. Self-rated mobility was assessed by asking whether respondents could walk 400 meters (yes, yes with difficulty but without help, not without help, or no). Cognitive function was assessed using the Mini-Mental State Examination. The presence of depressive symptoms was assessed using the 15-item Geriatric Depression Scale. Respondents' self-rated health was determined using a 5-point scale (very poor, poor, moderate, good, or very good). Results: Of the initial random sample of participants (N = 1000), 700 provided consent to participate and were community dwelling. Among the participants, 318 (45.4%) were users of ≥1 analgesic on a daily or as-needed basis. Only 23.3% of analgesic users took an analgesic on a daily basis. Factors associated with any analgesic use included female sex (odds ratio [OR], 1.78 [95% CI, 1.17-2.71]), living alone (OR, 1.46 [95% CI, 1.02-2.11]), poor selfrated health (OR, 2.6 [95% CI, 1.22-3.84]), and use of ≥10 nonanalgesic drugs (OR, 2.21 [95% CI, 1.26-3.87]). Among users of ≥1 oral analgesic, factors associated with opioid use included moderate (OR, 2.46 [95% CI, 1.17-5.14]) and poor (OR, 2.57 [95% CI, 1.03-6.42]) self-rated health. Opioid use (OR, 0.19 [95% CI, 0.04-0.86]) and daily analgesic use (OR, 0.16 [95% CI, 0.34-0.74]) were inversely associated with depressive symptoms. Pain in the previous month was reported by 71.4% of analgesic users and 26.4% of nonusers of analgesics. Conclusions: Analgesics were used by ∼50% of community-dwelling people aged ≥75 years. However, age was not significantly associated with increased use of analgesics in multivariate analysis. The majority of analgesic drugs were used on an as-needed rather than a daily basis (76.7% vs 23.3%, respectively). Factors most significantly associated with analgesic use were female sex, living alone, poor self-rated health, and use of ≥10 nonanalgesic drugs. © 2010 Excerpta Medica Inc. Source

Pharmacoepidemiological studies provide valuable information on the relationships between psychotropic drug use and adverse outcomes in older people. To minimize the influence of misclassification bias in pharmacoepidemiological studies, more emphasis should be given to methodological aspects of exposure assessment. This study evaluated the validity of a dosage assumption of one unit per day for measuring legend duration of psychotropic drug exposures among older people. Using data from the Finnish Prescription Register, the study analysed 62,320 psychotropic drug prescriptions dispensed for people aged≥75 years (n = 52,729) in September 2009. The proportions of prescriptions in which the prescribed dose deviated from one unit per day were assessed for categories and subcategories of psychotropic drugs. The prescription was considered misclassified (a) if the prescribed drug was intended for "as needed" use, (b) if the prescription included a dose range, or (c) if the prescribed dose was below or above one unit per day. Among antidepressants, less than every fourth (23.7%) prescription was misclassified. The proportions of misclassification varied substantially across subcategories, being 13.1% for selective serotonin reuptake inhibitors (SSRIs), 25.3% for other antidepressants and 53.8% for tricyclic antidepressants. Of the benzodiazepine and antipsychotic prescriptions, 79.9% and 57.6%, respectively, were misclassified. In conclusion, the dosage assumption of one unit per day is valid for measuring the legend duration of SSRI and other antidepressant exposures among older people. Among other psychotropic drugs, the dosage assumption is likely to lead to severe exposure misclassification. © 2013 John Wiley & Sons, Ltd. Source

Background: Pharmacoepidemiological studies assessing the associations between psychotropic drug use and adverse events in the elderly frequently employ automated pharmacy databases as the source of exposure data. However, information on the validity of these databases for estimating psychotropic drug exposures in elderly people is scarce. Objective: This study evaluated the validity of the Finnish Prescription Register for estimating current exposures to psychotropic drugs in elderly people. Furthermore, the potential change in the validity over time was determined. Methods: This was a population-based intervention study (GeMS; Geriatric Multidisciplinary Strategy for the Good Care of the Elderly) conducted between 2004 and 2007. Initially, 1000 randomly selected persons aged ≥75 years living in the City of Kuopio, Finland, in November 2003 were invited to participate in the study. Of these, 716 agreed to participate at baseline (2004) and 570 were still available for 3-year follow-up (2007). The validity of the Prescription Register was assessed by comparing it with the self-reported information collected by interviews in 2004 and in 2007 in the GeMS study. Using the self-reported data as a reference standard, sensitivity, specificity and Cohens κ statistic (measure of inter-rater agreement for qualitative [categorical] items) with 95% confidence intervals were computed for different categories and subcategories of psychotropic drugs, applying fixed-time windows of 4, 6 and 12 months. Results: In 2007, the sensitivity varied between psychotropic categories and subcategories, being generally highest with the 12-month time window(0.57-0.96). The specificity was highest with the 4-month time window (0.94-0.99), showing a slight tendency to decrease with an extended time window. The sensitivity and specificity were highest for antidepressants and antipsychotics, followed by benzodiazepines. The agreement was almost perfect (κ = 0.81-1.00) or substantial (κ= 0.61-0.80) for all categories and subcategories of psychotropic drugs. Few differences in validity were observed between the two years. Conclusion: Using self-reported data as a reference standard, the Prescription Register provides valid information on current exposures to antidepressants and antipsychotics in elderly people if the time window is selected with adequate consideration. However, the validity is lower for benzodiazepines, suggesting that other sources of information should be considered when performing pharmacoepidemiological studies. © 2010 Adis Data Information BV.
