Social, cultural and economic factors associated with self-medication.

INTRODUCTION: Self-medication is an increasingly frequent phenomenon worldwide; some studies suggest that there is a relationship with socio-economic and cultural factors. OBJECTIVE: To determine the prevalence of self-medication and its related factors in a Colombian city. MATERIALS AND METHODS: Cross-sectional descriptive study, in Pereira, Colombia. We selected 414 adults using simple randomization sampling with houses used as the observational unit. The IRIS-AM instrument was used to collect the information required. RESULTS: Four hundred and fourteen (414) people were interviewed, 62.6% were females, and mean age was 44 years; 77.5% of the sample had self-medicated at least once in their life and 31.9% during the last month. The most commonly used medications were: analgesics and antipyretics (44.3%), non-steroidal anti-inflammatory drugs and anti-rheumatic medication (36.4%), and anti-histamine medication (8.5%). The most commonly self-medicated symptoms were: headache (55.7%), cold (16.2%) and muscular pain (13.2%). Multivariate analysis revealed an association between self-medication throughout life and storing medications at home, and between a high level of education and having a favorable opinion of self-medication. Storing medications at home and recommending them to others were associated with self-medication during the previous 30 days. CONCLUSION: Self-medication rates were found to be similar to those reported globally, but there is not an established pattern for this practice. Associations were found between social and demographic variables and self-medication, which require further characterization. Intention to self-medicate has not been well-described in other studies, and may be an important indicator which will contribute to future understanding of this phenomenon.

Introducción. La automedicación es un fenómeno cada vez más frecuente a nivel mundial. Los estudios en este campo sugieren que hay una relación entre la automedicación y diversos factores sociodemográficos y económicos. Objetivo. Determinar la prevalencia de la automedicación y los factores relacionados en Pereira, Colombia. Materiales y métodos. Estudio descriptivo de corte transversal llevado a cabo en la población de Pereira. Se hizo un muestreo aleatorio por afijación proporcional en 414 adultos, y se desarrolló y aplicó la encuesta IRIS-AM ( Instrument for Systematic Data Collection of Self-Medication ). Resultados. Se encuestaron 414 personas, 62,6 % de las cuales eran mujeres; el promedio de edad fue de 44 años. La prevalencia de la automedicación fue de 77,5 % a lo largo de la vida y de 31,9 % en los 30 días previos. Los medicamentos más comúnmente utilizados fueron los analgésicos y antipiréticos (44,3 %), los antiinflamatorios no esteroideos (36,4 %), y los antihistamínicos (8,5 %). Los síntomas que llevaron a la automedicación con mayor frecuencia fueron la cefalea (55,7 %), el resfriado (16,2 %) y el dolor muscular (13,2 %). Los análisis multivariados mostraron asociación entre la automedicación a lo largo de la vida y guardar medicamentos en casa, así como entre tener un nivel superior de escolaridad y estar a favor de la automedicación. Los factores referentes a almacenar medicamentos y recomendarlos a otros se asociaron con la automedicación en los 30 días previos. Conclusiones. La prevalencia de la automedicación hallada en este estudio fue similar a la reportada previamente a nivel mundial; aun así, no existe un patrón establecido para esta práctica. Se evidenciaron las variables sociodemográficas asociadas con la automedicación, las cuales requieren una mejor caracterización. La intención de recurrir a la automedicación ha sido poco estudiada y podría ser un indicador importante para la medición y comprensión de este fenómeno.

Uso de hierro en forma de medicamento en gestantes colombianas / Pregnant Colombian females' iron in take in drug form

Objetivo Caracterizar el consumo de hierro en forma de medicamento en un grupo de embarazadas colombianas. Metodología Estudio observacional descriptivo, se obtuvo información de mujeres en control prenatal y/o atención del parto en 4 ciudades de Colombia. Las fuentes de información fueron entrevistas a gestantes y registros de historia clínica. Resultados La muestra fue de 1 637 mujeres en 15 instituciones. A 1 396 mujeres (85,3 %) les recomendaron consumir hierro, recomendación realizada por médico al 85,3 % de ellas, el 86,8 % tuvo adherencia al tratamiento. Al 84,7 % el hierro fue suministrado por la empresa aseguradora de salud, el 11,9 % lo compró a sus expensas. El 90,0 % de gestantes anémicas y el 82,8 % de las no anémicas consumieron hierro en forma de medicamento, en conjunto, en el 37,2 % de las gestantes el consumo de suplencia de hierro fue pertinente (es decir, lo necesitaban, se les recomendó y lo consumieron o no le necesitaban, no se recomendó y/o no lo consumieron). Discusión Se recomienda y se consume hierro independientemente de presentar anemia. Se invita a reflexionar sobre la utilidad de los programas que promueven el consumo masivo de esta sustancia en forma de medicamento durante el embarazo, programas que parecen desconocer las causas fundamentales de los problemas nutricionales que aquejan a la población.

Objective Describing a group of pregnant Colombian females' iron intake, in drug form. Methodology This was an observational descriptive study; information was collected in 4 Colombian cities regarding pregnant females during antenatal control or when giving birth. Information sources consisted of interviews with pregnant women and their clinical records. Results The sample consisted of 1,637 female sat tending 15 institutions. An iron intake was recommended for1, 396 women (85.3 %); a doctor made such recommendation in 85.3 % of cases and adherence was 86.8 %. Health insurance was used by 84.7 % of the females for supplying iron; 11.9 % of them bought it themselves. Iron intake as medication for anemic pregnant females was 90.0 % and 82.8 % in non-anemic ones. Iron intake supply was appropriate in 37.2 % of the pregnant females (i.e. they needed it, someone recommended it for them and they consumed it, or they didn't need it, someone didn't recommend it to them and/or they did not take it). Discussion Iron intake was recommended and consumed regardless of anemia status. The results invite to think on the usefulness of programs promoting the mass intake of iron as a medication during pregnancy. Such programs seem to be unaware of the fundamental causes of people's nutritional problems.

The concentration of out-of-pocket expenditures on complementary and alternative medicine in the United States.

CONTEXT: The most intense spenders on health services are considerably less healthy.49% report fair or poor health status compared to 15% of the general adult population and are elderly. Such findings have important implications for addressing national health-care spending because interventions targeting those people who are in poor health could theoretically generate dramatic cost savings. Although the popularity of complementary and alternative medicine (CAM) in the United States is well recognized, little is known about the distribution of out-of-pocket expenditures on CAM services. OBJECTIVE: This study examined the distribution of out-of-pocket expenditures on CAM health services in the United States. DESIGN: The research team used data from the 2007 National Health Interview Survey to examine the distribution in the United States of out-of-pocket expenditures on CAM services and the characteristics of adult (age ≥ 18 years) CAM users (n = 2972) according to spending. OUTCOME MEASURES: Using complex survey-design methods, the research team generated national estimates of expenditures on CAM services and used linear regression adjusted for covariates to determine whether self-reported health status predicted CAM spending. RESULTS: According to our estimates, in 2007, over 30 million adults reported out-of-pocket expenditures on CAM services, and of these individuals, 7.2 million were heavy CAM spenders with a mean annual expenditure of $1385. The highest quartile of CAM spenders accounted for $10 billion of the $13.9 billion spent nationally on CAM in 2007. Self-reported health status did not differ among groups with differing levels of CAM spending, ß = 1.00 (95% CI, 0.8-1.2). CONCLUSIONS: Out-of-pocket spending on CAM is concentrated. Just a quarter of CAM users account for over 70% of all expenditures on CAM services, and health status does not appear to be associated with level of CAM spending.

Public perception on the role of community pharmacists in self-medication and self-care in Hong Kong.

BACKGROUND: The choices for self-medication in Hong Kong are much diversified, including western and Chinese medicines and food supplements. This study was to examine Hong Kong public knowledge, attitudes and behaviours regarding self-medication, self-care and the role of pharmacists in self-care. METHODS: A cross-sectional phone survey was conducted, inviting people aged 18 or older to complete a 37-item questionnaire that was developed based on the Thematic Household surveys in Hong Kong, findings of the health prorfessional focus group discussions on pharmacist-led patient self management and literature. Telephone numbers were randomly selected from residential phone directories. Trained interviewers invited eligible persons to participate using the "last birthday method". Associations of demographic characteristics with knowledge, attitudes and beliefs on self-medication, self-care and role of pharmacists, and spending on over-the-counter (OTC) products were analysed statistically. RESULTS: A total of 1, 560 phone calls were successfully made and 1, 104 respondents completed the survey which indicated a response rate of 70.8%. 63.1% had adequate knowledge on using OTC products. Those who had no formal education/had attended primary education (OR = 3.19, 95%CI 1.78-5.72; p < 0.001), had attended secondary education (OR = 1.50, 95%CI 1.03-2.19; p = 0.035), and aged ≥ 60 years (OR = 1.82, 95% CI 1.02-3.26; p = 0.042) were more likely to have inadequate knowledge on self-medication. People with chronic disease also tended to spend more than HKD100 on western (OR = 3.58, 95%CI 1.58-8.09; p = 0.002) and Chinese OTC products (OR = 2.94, 95%CI 1.08-7.95; p = 0.034). 94.6% believed that patients with chronic illnesses should self-manage their diseases. 68% agreed that they would consult a pharmacist before using OTC product but only 45% agreed that pharmacists could play a leading role in self-care. Most common reasons against pharmacist consultation on self-medication and self-care were uncertainty over the role of pharmacists and low acceptance level of pharmacists. CONCLUSIONS: The majority of respondents supported patients with chronic illness to self-manage their diseases but less than half agreed to use a pharmacist-led approach in self-care. The government should consider developing doctors-pharmacists partnership programs in the community, enhancing the role of pharmacists in primary care and providing education to patients to improve their awareness on the role of pharmacists in self-medication and self-care.

Shopping for psoriasis medications on the Internet.

BACKGROUND: Numerous consumer products, including medicines, can be bought over the Internet. Previous reports indicate that patients are able to purchase the current available treatments, including expensive systemic and biological agents with side-effects, available for use on an outpatient basis. In France, as in most industrialized countries, these drug treatments are available only by prescription. Objective To evaluate whether psoriatic outpatients can buy the full range of psoriasis medications, including biological therapies, without a prescription, via the Internet. METHODS: One investigator acted as a consumer to purchase psoriasis treatments and complementary medicines over the Internet. The website search was limited to a 4-h period. All products had to be available for delivery in France, without a prescription, and be suitable for outpatient use. Key words for the Internet search were combinations of medicinal product names, 'psoriasis', 'shopping', 'pharmacy', 'parapharmacy', entered into two major search engines, Google and Yahoo. RESULTS: The investigator identified 47 websites offering a total of 340 products. All treatments, including biological therapies (etanercept, adalumimab and efaluzimab), were available for purchase with the exception of calcitriol and alefacept, with median prices being higher than the French price. CONCLUSION: This study shows that it is possible for consumers to purchase the majority of treatments for psoriasis via the Internet, including systemic therapies and even the most recent and expensive products such as biological agents, without a prescription.

Self-care as a response to diarrhoea in rural Bangladesh: empowered choice or enforced adoption?

The literature is growing on the subject of coping strategies. However, with the exception of some work on the promotion of oral rehydration therapy (ORT), very few studies have examined coping strategies as a response to the ongoing diarrhoeal disease burden. This is particularly relevant in the case of self-care, previously documented as the most readily implemented treatment in the developing world and an increasingly common health behaviour in rural Bangladesh. This study analysed the socioeconomic factors that influence the adoption of self-care and the role that varied asset availability plays in relation to households choosing, or being forced to implement, a coping strategy. Qualitative methods were used to collect data from three villages in Nilphamari District, North West Bangladesh, in 2004. The findings produced a detailed picture of asset availability and its influence on household use of self-care treatment practices. The strong role of aspects of social capital in building human capital was highlighted, as well as how these aspects of social capital can assist household welfare through self-care in times of diarrhoeal disease. In contrast, households exhibiting weakened social and human capital were more excluded from information on appropriate self-care treatments. Development agencies and health care policies might therefore strengthen levels of household resilience to diarrhoeal disease more cost-effectively by focusing on activities that facilitate self-care through support of social networks and education channels.

Economics of self-medication: theory and evidence.

A pervasive phenomenon in developing countries is that self-prescribed medications are purchased from drug vendors without professional supervision. In this article we develop a model of self-medicating behavior of a utility-maximizing consumer who balances the benefits and risks of self-medication. The empirical investigation focuses on the role of income and health insurance on the use of self-medication. Our data are from the World Bank's Living Standards Measurement Survey of Vietnam, 1997-1998. The results show that self-medication is an inferior good at high income levels and a normal good at low income levels, and it shows a strong and robust negative insurance effect.

Use of dietary supplements by patients in a family practice clinic.

BACKGROUND: Many Americans are using alternative medical therapies as well as nutritional or dietary supplements that include vitamins, minerals, herbal products, tissue extracts, protein solutions, and other chemicals. Potential for both good and harm exists in taking many of these preparations. METHODS: We surveyed 200 consecutive patients older than 18 years attending a family practice clinic. In addition to demographic data, we asked them about their intake of dietary supplements during the past year, perceived benefits from supplements, source of information, estimated cost of products, and whether their physician knew that they were taking the product. RESULTS: Fifty-two percent of the patients had taken 1 or more supplements during the past year, 18 percent used 2 to 5 supplements, and 3 percent took 6 to 13 different dietary supplements. Twenty-nine percent took them for diet and energy enhancement, and 24 percent for cancer prevention and immune system enhancement. The media was the principal source of patient information. Thirty-three percent of patients had not told their physician of their supplement use. The average estimated expenditure was $ 6.60 per month with a maximum of $ 68.90 per month. Eighty-two percent of the supplements taken were vitamins and minerals at recommended daily allowances (RDAs), whereas 18 percent were other supplements such as herbal products, megadose vitamins, and protein and amino acid preparations. Demographically, only educational level correlated significantly with supplement consumption. Patients with a high school education took significantly fewer supplements than those with more advanced education. CONCLUSIONS: Physicians should have a dialogue with their patients about dietary supplements because their use is widespread. Whereas many supplements are taken in safe doses, for others neither safety nor effectiveness has been proven, and for a few there are known toxicities. Additional research is needed to investigate both the safety and effectiveness of these products.

Alternative medicine: cost and subjective benefit in rheumatoid arthritis.

Seventy-eight patients with seropositive rheumatoid arthritis were asked about money spent in an attempt to help their arthritis. This included expenditure on alternative medicine, aids for the home, and conventional medicine. Most money was spent on, and most benefit was derived from, aids for the home. Sixty per cent of the patients had tried alternative medicine, but expenditure on this was relatively low and only a small proportion found it helpful.
