Improving doctors' prescribing behaviour through reflection on guidelines and prescription feedback: a randomised controlled study.

Background—It is difficult to put research findings into clinical practice by either guidelines or prescription feedback. Aim—To study the effect on the quality of prescribing by a combined intervention of providing individual feedback and deriving quality criteria using guideline recommendations in peer review groups. Methods—199 general practitioners in 32 groups were randomised to participate in peer review meetings related to either asthma or urinary tract infections. The dispensing by the participating doctors of antiasthmatic drugs and antibiotics during the year before the intervention period provided the basis for prescription feedback. The intervention feedback was designed to describe the treatment given in relation to recommendations in the national guidelines. In each group the doctors agreed on quality criteria for their own treatment of the corresponding diseases based on these recommendations. Comparison of their prescription feedback with their own quality criteria gave each doctor the proportion of acceptable and unacceptable treatments. Main outcome measure—Difference in the prescribing behaviour between the year before and the year after the intervention. Results—Before intervention the mean proportions of acceptably treated asthma patients in the asthma group and urinary tract infection (control) group were 28% and 27%, respectively. The mean proportion of acceptably treated patients in the asthma group was increased by 6% relative to the control group; this difference was statistically significant. The mean proportions of acceptable treatments of urinary tract infection before intervention in the urinary tract infection group and asthma (control) group were 12% for both groups which increased by 13% in the urinary tract infection group relative to the control group. Relative to the mean pre-intervention values this represented an improvement in treatment of 21% in the asthma group and 108% in the urinary tract infection group. Conclusions—Deriving quality criteria of prescribing by discussing guideline recommendations gave the doctors a basis for judging their treatment of individual patients as acceptable or unacceptable. Presented with feedback on their own prescribing, they learned what they did right and wrong. This provided a foundation for improvement and the process thus instigated resulted in the doctors providing better quality patient care.

Effect of vitamin D on musculoskeletal pain and headache: A randomized, double-blind, placebo-controlled trial among adult ethnic minorities in Norway

Summary Vitamin D supplementation for 16 weeks did not reduce musculoskeletal pain or headache in this randomized, double‐blind, placebo‐controlled study among ethnic minorities living in Norway. ABSTRACT Immigrants from South Asia, the Middle East, and Africa living in Northern Europe frequently have low vitamin D levels and more pain compared to the native Western population. The aim of this study was to examine whether daily vitamin D3 (25 &mgr;g/d or 10 &mgr;g/d) supplementation for 16 weeks would improve musculoskeletal pain or headache compared to placebo. This randomized, double‐blind, placebo‐controlled, parallel‐group trial recruited 251 participants aged 18 to 50 years, and 215 (86%) attended the follow‐up visit. The pain measures were occurrence, anatomical localization, and degree of musculoskeletal pain, as measured by visual analogue scale (VAS) score during the past 2 weeks. Headache was measured with VAS and the Headache Impact Test (HIT‐6) questionnaire. At baseline, females reported more pain sites (4.7) than males (3.4), and only 7% reported no pain in the past 2 weeks. During the past 4 weeks, 63% reported headache with a high mean HIT‐6 score of 60 (SD 7). At follow‐up, vitamin D level, measured as serum 25(OH)D3, increased from 27 nmol/L to 52 nmol/L and from 27 nmol/L to 43 nmol/L in the 25‐&mgr;g and 10‐&mgr;g supplementation groups, respectively, whereas serum 25(OH)D3 did not change in the placebo group. Pain scores and headache scores were improved at follow‐up compared with baseline. The use of vitamin D supplements, however, showed no significant effect on the occurrence, anatomical localization, and degree of pain or headache compared to placebo.

Self-medication with OTC analgesics among 15 - 16 year-old teenagers

BACKGROUND OTC analgesics were released for sale outside pharmacies in Norway in 2003. This study assesses indications and frequency of use of these drugs among 15-16 year-old teenagers in Norway after 2003. MATERIAL AND METHOD We developed a questionnaire, which contained 65 questions with one or more response options. This was given to all pupils in the final grade at six junior high schools in a town with 60,000 inhabitants (Drammen). RESULTS 367 of 626 (58.6 %) pupils participated. 50 % of the boys and 71 % of the girls had used OTC analgesics during the last four weeks; 26 % of them on a daily or weekly basis. Girls experienced episodes of pain more frequently than boys, but the proportion of episodes treated with analgesics did not differ between the sexes. Headache and muscle pain were common. Half of those with severe headache/migraine used OTC analgesics on a daily or weekly basis. The teenagers reported several reasons for experiencing pain and discomfort, such as long time spent in front of various screens, tight time schedules with physical exercise and friends, drinking too little and much noise in the classroom. INTERPRETATION Use of OTC analgesics has increased considerably among Norwegian teenagers. Drug-induced headache may occur as an adverse event. If more effort is made to improve life situations that adolescents perceive as painful and a cause of discomfort, the need for OTC analgesics may be reduced.

Prevalence and risk factors for postpartum depressive symptoms in Argentina: a cross-sectional study

Introduction Postpartum depression is a prevalent disorder with negative consequences for women, infants, and the family as a whole. Most studies of this disorder have been conducted in Western countries, and studies from developing countries are few. In this paper, we report the first – as far as we are aware – study of the prevalence and risk factors associated with postpartum depressive symptoms in Argentina. Materials and methods The study participants were 86 women attending 6 week checkups, (range 4–12 weeks) postpartum at a private health care center in the metropolitan area of Buenos Aires. The women completed the Edinburgh Postnatal Depression Scale (EPDS) and a questionnaire collecting demographic and obstetric data. Data were described as proportions (percentages). Differences between proportions were assessed with chi-squared tests. To control for possible confounders, we fitted bivariate logistic regression models in which the dependent variable was an EPDS sum score of <10 versus a score of ≥10. Results We found a high prevalence of depressive symptoms. A total of 32 women (37.2%) had an EPDS score of ≥10, 16 (18.6%) had a score between 10 and 12, and 16 (18.6%) had a score of ≥13. In our sample, an EPDS score of ≥10 was significantly associated with multiparity (odds ratio [OR] =3.58; 95% confidence interval [CI]: 1.13–11.30; P=0.030), pregnancy complications (OR =3.40; 95% CI: 1.03–11.26; P=0.045), labor complications (OR =11.43; 95% CI: 1.71–76.61; P=0.012), cesarean section (OR =4.19; 95% CI: 1.10–16.01; P=0.036), and incomplete breast-feeding (OR =5.00; 95% CI: 1.42–17.54; P=0.012). Conclusion Our results indicate that postpartum depression may be prevalent in Argentina, and may be associated with incomplete breast-feeding, cesarean section, perinatal complications and multiparity. The prevalence and risk factors for postpartum depression has not been described previously and is a considerable health-related problem among women. Argentinian health professionals should be aware of the high prevalence rate and possible risk factors so that these women and families can be identified and receive adequate support and treatment.

High‐frequency use of over‐the‐counter analgesics among adolescents: reflections of an emerging difficult life, a cross‐sectional study

AIMS To examine characteristics of 15- to 16-year-old adolescents who used over-the-counter analgesics daily to weekly (high-frequency users) as compared to those who used less or no analgesics (low-frequency users). Further to analyse the differences in pain experience, lifestyle, self-esteem, school attendance and educational ambition. METHODS An anonymous cross-sectional questionnaire-based study. The questionnaire covered the use of over-the-counter analgesics, pain experience, sociodemographics, lifestyle factors, self-esteem, school absence and future educational plans. The study took place in the 10th grade in six junior high schools in a medium-sized town in Norway. The local sales data for analgesics and antipyretics were close to the national average. We invited 626 adolescents to participate. Of the 367 adolescents (59%) who responded, 51% were girls. Associations between the frequency of use of over-the-counter analgesic and the mentioned variables were analysed using multiple logistic regression. RESULTS In total, 26% (42 boys and 48 girls) used over-the-counter analgesics daily to weekly. These high-frequency users experienced more widespread pain, slept less, had more paid spare-time work, drank more caffeinated drinks, participated more often in binge drinking, had lower self-esteem, less ambitious educational plans and more frequent school absence than did the low-frequency users. These associations remained significant when controlling for gender, cultural background and self-evaluated economic status. CONCLUSION Adolescent, who are high-frequency users of over-the-counter analgesics, suffer more pain and have identifiable characteristics indicative of complex problems. Their ability to handle stress appears to be discordant with the kind of situations to which they are exposed. The wear and tear associated with allostatic mechanisms counteracting stress may heighten their pain experience.

Effect of vitamin D3 supplementation on glycated hemoglobin (HbA1c), fructosamine, serum lipids, and body mass index: a randomized, double-blinded, placebo-controlled trial among healthy immigrants living in Norway

Objective Despite the suggested role of vitamin D in the prevention of diabetes and cardiovascular disease or its risk factors, the evidence is not consistent and there is a paucity of randomized controlled trials in this field. We aimed to investigate the effect of 16-week daily vitamin D3 supplementation on glycated hemoglobin (HbA1c), fructosamine, body mass index (BMI), and serum lipids. Design Double-blind, randomized, placebo-controlled trial. Setting Immigrant community centers in Oslo, Norway. Participants 251 healthy adults aged 18–50 years with a non-Western immigrant background. All participants performed the baseline test and 215 (86%) returned to the follow-up test. Intervention 16 weeks of daily oral supplementation with either 10 μg vitamin D3, 25 μg vitamin D3, or placebo. Main outcome measures Difference in absolute change during the 16-week intervention between the intervention groups combined (10 or 25 μg of vitamin D3/day) and placebo, in HbA1c, fructosamine, serum lipids (total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides), and BMI. Results A total of 215 (86%) participants completed the study. Serum 25-hydroxyvitamin D increased from 29 nmol/L at baseline to 49 nmol/L after intervention, with little change in the placebo group. However, there was no difference in change of HbA1c between those receiving vitamin D3 compared with placebo (mean difference: 0.01% (95% CI −0.04 to 0.06, p=0.7)). Neither did the vitamin D3 supplementation have any effect on the other end points: fructosamine, serum lipids, and BMI. Conclusions 16-week vitamin D3 supplementation to healthy immigrants from South Asia, the Middle East, or Africa and now living in Norway with low vitamin D status did not improve HbA1c, fructosamine, lipid profiles, or BMI. An updated meta-analysis of similar published trials showed that our results were generally consistent with those of other studies. Trial registration number NCT01263288.

Vitamin D levels during pregnancy and associations with birth weight and body composition of the newborn: a longitudinal multiethnic population-based study

We investigated associations between serum 25-hydroxyvitamin D (25(OH)D) in pregnancy and birth weight and other neonatal anthropometric measures. The present study was a population-based, multiethnic cohort study of 719 pregnant women (59 % ethnic minorities) in Oslo, Norway, delivering a singleton neonate at term and with birth weight measurements. In a representative sample, anthropometric measurements were taken. Maternal 25(OH)D was measured at gestational weeks 15 and 28. Women with 25(OH)D <37 nmol/l were recommended vitamin D3 supplementation. Separate linear regression analyses were performed to model the associations between 25(OH)D and each of the outcomes: birth weight, crown-heel length, head circumference, abdominal circumference, sum of skinfolds, mid-upper arm circumference and ponderal index. In early pregnancy, 51 % of the women were vitamin D deficient (25(OH)D<50 nmol/l). In univariate analyses and in models adjusting for maternal age, parity, education, prepregnancy BMI, season, gestational age and neonate sex, maternal 25(OH)D was significantly associated with birth weight, head circumference, abdominal circumference and ponderal index (P<0·05 for all), when used as a continuous variable and categorised (consistently low, consistently high, increasing and decreasing level). However, after adjusting for ethnicity, 25(OH)D was no longer associated with any of the outcomes. Sex-specific associations for abdominal circumference and sum of skinfolds were found (P for interaction<0·05). In conclusion, in a multiethnic cohort of pregnant women with high prevalence of vitamin D deficiency, we found no independent relation between maternal vitamin D levels and any of the neonatal anthropometric measures, and the strong association between ethnicity and neonatal outcomes was not affected by maternal vitamin D status.

Effect of vitamin D3-supplementation on bone markers (serum P1NP and CTX): A randomized, double blinded, placebo controlled trial among healthy immigrants living in Norway

Objective Vitamin D is essential for the maintenance of calcium homeostasis and bone mineralization; and low serum 25-hydroxyvitamin D (s-25-(OH)D) concentrations are associated with increased bone turnover. However, there is a lack of randomized controlled trials that have investigated the effect of vitamin D treatment on bone turnover in immigrant populations. We aimed to investigate the effect of 16-week daily vitamin D3 supplementation on bone formation marker serum procollagen type 1 amino-terminal propeptide (P1NP) and bone resorption marker C-terminal crosslinked telopeptide of type I collagen (CTX). Design Double-blind, randomized, placebo-controlled trial. Setting Immigrant community centers in Oslo, Norway. Participants 251 healthy adults aged 18–50 years with a non-Western immigrant background were recruited. Intervention 16 weeks of daily oral supplementation with either 10 μg vitamin D3, 25 μg vitamin D3, or placebo. Main outcome measures Difference in change during the 16-week intervention between the intervention groups combined (10 or 25 μg of vitamin D3/day) and placebo, in serum P1NP and serum CTX. Results A total of 214 (85%) participants completed the study. S-25-(OH)D increased from 29 nmol/L at baseline to 49 nmol/L in the intervention group with no significant change in the placebo group. However, there was no difference in change of serum P1NP (mean difference: − 1.2 μg/L (95% CI: − 5.4, 2.9, P = 0.6)) and serum CTX (mean difference: − 0.005 μg/L (95% CI: − 0.03, 0.02, P = 0.7)) between those receiving vitamin D3 supplementation compared with placebo. The plasma PTH had decreased by a mean of − 1.97 pmol/L (95% CI: − 2.7, − 1.3, P < 0.0001) in the vitamin D3 group compared to placebo. Conclusions Supplementation with 10 or 25 μg oral vitamin D3 during winter and spring for 16 weeks did not significantly affect serum P1NP and serum CTX, despite increasing s-25(OH)D and decreasing PTH in a healthy immigrant population with low baseline vitamin D status.

How adolescents experience and cope with pain in daily life: a qualitative study on ways to cope and the use of over-the-counter analgesics

Objective The aim of this study was to describe how different adolescents experience and manage pain in their daily life, with a focus on their use of over-the-counter analgesics. More specifically, the aim was to explore different patterns among the adolescents in pain descriptions, in the management of pain, in relationships with others, and in their daily life. Design Qualitative semistructured interviews on experiences with pain, pain management and involvement of family and friends during pain. Pain and stress management strategies and attachment theory will be in focus for interpretations. Participants and setting 25 participants aged 15–16-years from six different junior high schools, both genders, with and without immigrant background were interviewed at their local schools in Norway. Results We identified 4 groups of adolescents with similarities in attitudes and management strategies to pain: ‘pain is manageable’, ‘pain is communicable’, ‘pain is inevitable’ and ‘pain is all over’. The participants within each group differed in how they engaged their parents in pain; how they perceived, communicated and managed pain; and how they involved emotions and used over-the-counter analgesics. Conclusions The adolescents’ different involvement with the family during pain related to their pain perception and management. Knowledge of the different ways of approaching pain is important when supporting adolescents and may be a subject for further research on the use of over-the-counter analgesics in the family.
