ABSTRACT Statistics and prescription database studies show that analgesics are widely utilized, but do not tell anything about either the factors behind analgesic use or how over-the-counter (OTC) analgesics are being used. We aimed to study the prevalence of frequent use of prescribed and OTC analgesics. We also investigated the background factors related to frequent analgesic use and assessed rationality of analgesic usage patterns. We addressed a postal survey to a random stratified population sample of 6500 Finnish people aged 15-74 years. The response rate was 71% (n=4542) after exclusion of unobtainable addressees (n=68). Individuals reporting analgesic use 'daily' or 'a few times a week' were categorized as frequent users. After adjusting for age and sex, the overall prevalence of daily analgesic use was 8.5%, and the prevalence of analgesic use a few times a week 13.6%. The adjusted prevalence of using exclusively prescribed analgesics daily or a few times a week was 8.7%, and that of utilizing purely OTC analgesics 8.8%. The overall prevalence of concomitant frequent use of both prescribed and OTC analgesics was 4.6%. Multinominal logistic regression analyses showed that frequent analgesic use was related especially to daily or continuous pain and high pain intensity. Low mood and not being employed also increased the probability for daily analgesic use. Frequent analgesic use seems to be common at population level. Concomitant use of both prescribed and OTC analgesics can be considered irrational, as it increases the risk of adverse events.

    ABSTRACT: Pain prevalence studies are important as they illustrate the magnitude of pain problems in a certain patient population, such as patients living with a spinal cord injury (SCI). Strikingly, reported pain prevalence rates in SCI patients are found to vary greatly, while determinants for the differences between pain prevalence reports remain unclear. We here aim to identify determinants for the differences (heterogeneity) in pain prevalence reports through a systematic review of all SCI pain prevalence reporting studies. Literature search was done using Medline, Cumulative Index to Nursing and Allied Health Literature, ISI Web of Knowledge and Embase. Data abstraction was performed while blinded and was followed by meta-(regression)-analyses. We identified 82 studies. Study design-related determinants of SCI pain prevalence reports were pain definition strictness (mild, moderate or high), primary study goal (pain study or not), data source (retrospective or not), and in a limited number of cases response/attrition rates. While correcting for these items, population characteristics correlating with pain prevalence rates were both proportion of patients with a depression and average time after injury (positive correlations). Between-study heterogeneity may remain even after the identification/correction of above-mentioned causes of heterogeneity.Pain after SCI does seem to relate to the duration of the injury and depression, yet major causes of bias in reported pain prevalence are found to be related to the primary study goal (pain study or not), choice of pain definition and the use of retrospective data.

    ABSTRACT: The characteristics of peptic ulcer disease (PUD) are changing. To evaluate time trends in the incidence of PUD and its complications in hospitalised patients at the beginning of the 21st century, drug therapies in out-patient care as a risk factor for recurrent PUD, and medication used by PUD patients compared with the background population. In this retrospective epidemiologic cohort study, data from the years 2000-2008 came from The Hospital District of Helsinki and Uusimaa, and the Finnish Care Register. All hospitalised adult patients with PUD in the capital region of Finland were included. The data were linked with nationwide Prescription Register of the Finnish Social Insurance Institution allowing detailed individual medicine purchase data. A total of 9951 peptic ulcers were detected among 8146 individual patients during the study period. The mean annual incidence of all peptic ulcers decreased from 121/100 000 (95% CI: 117-125) in 2000-2002, to 79 (95% CI: 76-82) in 2006-2008 [Incidence rate ratio = 0.62 (95% CI: 0.58-0.64), P < 0.001 after age and sex adjustment]. Decrease in incidence was seen in all age groups and in both sexes. The overall rate of severe complications of PUD was reduced. One-year cumulative incidence of recurrent ulcers was 13%. Use of several drugs was associated with increased risk for recurrence. The purchases of various drugs were more common among PUD patients compared with background population. Both the incidence and complication rates have markedly decreased during the study period. Recurrent peptic ulcer disease was associated with polypharmacy.

    ABSTRACT: Objectives: The aims of the study were to examine the association between immigrant background and medicine use for headache and stomach-ache among adolescents, and whether symptoms of headache and stomach-ache could explain the differences in medicine use. Methods: We used data from the Danish contribution to the WHO-affiliated international cross-sectional survey Health Behaviour in School-aged Children (HBSC) in 2006. Among boys, a total of 4170 ethnic Danes, 244 descendants of immigrants, and 224 immigrants participated. Among girls, 4310 ethnic Danes, 264 descendants of immigrants, and 232 immigrants were included. The associations between migrant background and medicine use for headache and stomach-ache by means of multilevel multivariate logistic regression analyses adjusted for age group, symptoms and the clustering effect of school and stratified by sex due to interactions. Results: Among boys, the risk of medicine use for stomach-ache was higher for immigrants (odds ratio (OR), 1.54; 95% confidence intervals (CI), 0.99-2.44)) and descendants (OR, 1.97 (1.33-2.94)) compared to ethnic Danes. Similar associations were found for use of medicine for stomach-ache for immigrant girls (OR, 1.55 (1.12-2.15) and use of medicine for headache among boys (immigrants (OR, 1.36 (1.02-1.97 and descendants (1.48 (1.12-1.97)). Symptoms of aches were all independently associated with medicine use. After adjusting for these factors the association between immigrant background and medicine use attenuated slightly. Conclusion: Among adolescents in Denmark, the risk of medicine use for headache and stomach-ache was higher for immigrants and descendants as compared to ethnic Danes, with the exception of medicine use for headache among girls.
