The prescribing of psychotropic drugs by primary care physicians: an international collaborative study

Gender Differences in the Prevalence of Mental Health, Psychological Distress and Psychotropic Medication Consumption in Spain: A Nationwide Population-Based Study

BACKGROUND

To assess gender differences in the prevalence of self-reported mental disorders, psychological distress and psychotropic drug consumption, and to identify sociodemographic and health-related variables associated with these conditions in the male and female population (aged ≥ 18 years).

METHODS

A cross-sectional study was carried on 22,141 subjects aged 18 and over, using data from the Spanish National Health Interview Survey 2017.

RESULTS

We found an overall prevalence of mental disorders, psychological distress and psychotropic drug consumption of 13.8%, 18.3% and 13.9%, respectively. After multivariable adjustment, women showed significantly increased probabilities of 1.74-fold for mental disorders, 1.26-fold for psychological distress and 1.26-fold for psychotropic drug consumption compared to men. Variables such as gender, age, nationality, marital status, educational level, self-rated health, the presence of different chronic disorders, alcohol consumption and smoking habit were independently associated with mental disorders, psychological distress and psychotropic drug consumption. Several variables showed a differential effect on mental health status and psychotropic drug consumption according to gender.

CONCLUSIONS

Women suffer from mental disorders, experience psychological distress and consume psychotropic drugs significantly more than men in Spain. Possible explanations for these results may be related to differences in emotional processing, willingness to report diseases and even intrinsic biological traits. Screening for mental health status and psychotropic drug consumption should be considered, particularly in Spanish women, younger adults and individuals who are not married, are obese, have poor self-rated health, suffer from chronic diseases or have a smoking habit.

[Consumption of psychotropic medications in primary healthcare in Ribeirão Preto, São Paulo State, Brazil]

The consumption of psychotropic drugs is considered a public health problem, due to the potential for addiction and the occurrence of adverse events. In this context, the current study aimed to characterize the consumption of psychotropic medications dispensed in primary healthcare units in Ribeirão Preto, São Paulo State, Brazil. This ecological study consulted the Hygia database from 2008 to 2012. The following variables were extracted: psychotropic drugs dispensed, amount dispensed per year, and patients' sex and age bracket. For each psychotropic drug, we calculated the defined daily dose per 1,000 inhabitants/day (DDD/1,000PD), defined daily dose per 1,000 inhabitants/day considering 75% of the population (DDD75%/1,000PD) who withdrew medicines through the Brazilian Unified National Health System (SUS), and the prescribed daily dose (PDD). The study compared the population growth rate to the growth in the medicines' consumption. A total of 1,577,241 patients were identified who withdrew medications during the study period, of whom 287,373 (18.2%) used at least one drug subject to special control. There was an increase in the total consumption of psychotropic drugs (DDD/1,000PD), but comparison to the population growth rate showed that only sertraline (p = 0.021), risperidone (p = 0.034), and clonazepam (p = 0.043) presented higher growth rates. The PDD for seven drugs were higher than the World Health Organization (WHO) DDD. Identifying discrepancies between DDD and PDD can be useful as a strategy for screening patients eligible for pharmaceutical care, since they can contribute to the prevention of morbidity and mortality related to medications.

Management of work-related common mental disorders in general practice: a cross-sectional study

BACKGROUND

General practitioners (GPs) often manage individuals with work-related common mental disorders (CMD: depressive disorders, anxiety and alcohol abuse). However, little is known about the ways in which they proceed. The aim of this study is to analyze GPs' management and patterns of referral to other health professionals of patients with work-related CMD and associated factors.

METHOD

We used data from a cross-sectional study of 2027 working patients of 121 GPs in the Nord - Pas-de-Calais region in France (April - August 2014). Statistical analyses focused on patients with work-related CMD detected by the GP and examined the ways in which GPs managed these patients' symptoms. Associations between patient, work, GP and contextual characteristics and GPs' management were explored using modified Poisson regression models with robust variance.

RESULTS

Among the 533 patients with work-related CMD in the study, GPs provided psychosocial support to 88.0%, prescribed psychotropic treatment to 82.4% and put 50.7% on sick leave. Referral rates to mental health specialists and occupational physicians were respectively 39.8 and 26.1%. Several factors including patients' characteristics (occupational and sociodemographic), GPs' characteristics and environmental data were associated with the type of management used by the GP.

CONCLUSION

Our study emphasizes the major and often lonesome role of the GP in the management of patients with work-related CMDs. Better knowledge of the way GPs manage those patients could help GPs in their practice, improve patients care and be a starting point to implement a more collaborative care approach.

Trends in the consumption rates of benzodiazepines and benzodiazepine-related drugs in the health region of Lleida from 2002 to 2015

Background

The high prevalence and long-term use of benzodiazepines (BZDs) treatment are debated topics because of the risk they can cause to the patients. Despite the current information on the risk-benefit balance of these drugs, their consumption remains particularly high. We determined the trend in the consumption prevalence of benzodiazepines (BZDs) and drugs related to BZDs (Z-drugs) in the population of the Health Region of Lleida to explore patterns of use and the associated characteristics associated between 2002 and 2015.

Methods

An analysis of secular trends was carried out between 2002 and 2015; the databased included all individuals from the Health Region of Lleida, which had 358,157 inhabitants in 2015, that consumed BZDs. The consumption of BZDs was evaluated using prescription billing data from the Public Health System. All types of BZDs and BZD analogues that had been approved by the drug agency were included. Trends by age and sex were investigated.

Results

Over the whole study period, a total of 161,125 individuals accounted for 338,148 dispensations. Overall, 59% were women, and the mean age was 56 years. The dispensing prevalence of BZDs use in 2015 was 14.2% overall —18.8% in women and 9.6% in men—and was 36% in those over 65 years. According to the half-life of BZDs, the prevalence of short-intermediate BZD use, intermediate-long BZD use, and Z-drugs use was 9.7, 5.5 and 0.8%, respectively. The evolution of the annual prevalence of BZD dispensing showed a progressive decline, from 15.3% in 2002 to 14.2% in 2015, which was attributed to a decrease in the consumption of intermediate-long half-life BZDs (8.0% vs. 5.5%) and Z-drugs (1.4% vs. 0.8%).

Conclusion

The dispensing prevalence of BZDs and Z-drugs was high, although a small reduction was observed during this time period. The dispensing prevalence was especially high in the population over 65, despite the risk of cognitive decline and falls. Integral actions are required to lower the BZD prescription rate.

Changes in Prescription of Psychotropic Drugs After Introduction of Polypharmacy Reduction Policy in Japan Based on a Large-Scale Claims Database

BACKGROUND AND OBJECTIVES

In Japan, polypharmacy reduction policy, which reduces the reimbursement of medical cost, was introduced to address unnecessary psychotropic polypharmacy. The rule was applied to the prescriptions of three or more anxiolytics or three or more hypnotics in the policy introduced in 2012. The prescriptions of four or more antidepressants or four or more antipsychotics were added to the rule in the policy revised in 2014. Furthermore, the prescriptions of three or more drugs of anxiolytics, hypnotics, antidepressants, or antipsychotics were subject to the reduction criteria of the policy revision in 2016. Benzodiazepine receptor agonists (BZs) are classified both into anxiolytics and hypnotics, and the reduction rule was not applied to the category of BZs before April 2018. This study aimed to examine the effect of the policy on the prescriptions of four drug categories as well as BZs from the point of view of the number of drugs and doses.

METHODS

This was a retrospective observational study using a large-scale Japanese health insurance claims database. Patients who were prescribed at least one psychotropic drug (anxiolytic, hypnotic, antidepressant, or antipsychotic) during the study period (from April 2011 to March 2017) were selected. Segmented regression analysis was used to analyze the proportions of patients with three or more or four or more drugs as well as patients above clinically recommended doses, and the means of the average daily doses by drug category.

RESULTS

A total of 312,167 patients were identified as a study population. The proportions of patients with three or more drugs in anxiolytics, hypnotics, antidepressants, and antipsychotics significantly decreased after the introduction or revisions of the policy, but not BZs. The proportions of patients with three or more drugs in March 2017 were 0.9%, 2.0%, 1.2%, 2.4%, and 8.9% in anxiolytics, hypnotics, antidepressants, antipsychotics, and BZs, respectively. The effect of the policy in reducing the proportions of patients above clinically recommended doses was identified in antipsychotics after the revision in 2016, but not identified in the sum of anxiolytics and hypnotics as well as BZs after the revision in 2014, and antidepressants after the revision in 2016. The proportions of monotherapy were increased from April 2011 to March 2017 only for antidepressants (76.9% → 80.8%) and antipsychotics (79.8% → 82.1%), and not changed or decreased for anxiolytics (85.2% → 85.7%), hypnotics (78.6% → 77.6%), sum of anxiolytics and hypnotics (68.1% → 65.7%), BZs (68.0% → 67.3%), and sum of psychotropic drugs (52.1% → 49.9%).

CONCLUSIONS

The polypharmacy reduction policy reduced the proportions of patients with three or more drugs in four drug categories, but not BZs. Only limited effects were seen for reducing the proportions of patients above clinically recommended doses. The policy was revised in April 2018 again. Further investigation is needed to examine the effect of the revision in 2018.

Does Early-Life Misfortune Increase the Likelihood of Psychotropic Medication Use in Later Life?

Life-course research has linked childhood experiences to adult mental illness, but most studies focus on anxiety or depressive symptoms, which may be transient. Therefore, this study investigates whether childhood misfortune is associated with taking psychotropic medication, a measure reflecting an underlying chronic mental disorder. Data are from three waves of a national survey of 2,999 U.S. men and women aged 25-74 years. Four domains of childhood misfortune (childhood socioeconomic status, family structure, child maltreatment, and poor health) are considered-specified as separate domains and a single additive measure-as key predictors of psychotropic medication use. Findings reveal an association between additive childhood misfortune and adult psychotropic medication use, net of adult risk factors. Psychotropic medication use is also more likely during the 20-year study for adults who experienced maltreatment and poor health during childhood. These results reveal the importance of early intervention to reduce consumption of psychotropic medications and associated costs.

Male and female physicians show different patterns of gender bias: A paper-case study of management of irritable bowel syndrome

Aims: Research has raised concerns about gender bias in medicine, i.e. that men and women might be treated differently due to gender-stereotyped attitudes among physicians. The authors investigated gender differences in medical management of a common health problem, irritable bowel syndrome (IBS). Method: In a national examination for Swedish house officers, the examinees were allocated to suggest management of IBS in either a male or female paper-patient. The case description was identical in both genders with the exception of prior prostate and gynaecological symptoms. The open answers were coded for analysis. A total of 289 physicians (45% women) participated. Chi-squared tests were used to measure differences in proportions. Results: In variables focusing on medication, weight, gynaecological problems, tobacco, alcohol, thyroid function, proposed diagnoses, X-ray of the colon, and advice about lifestyle, significant or close to significant gender differences were seen. Both male and female physicians made gender differences but they did not show the same pattern of differences. Conclusions: The results suggest that gender bias is involved in medical management of IBS but men and women physicians may show disparate patterns of gender bias. There is a need for larger studies on gender differences in medical management with designs making it possible to consider the gender of both the patient and the physician. Furthermore, the results call attention to `knowledge-mediated gender bias', a phenomenon implying that once knowledge about gender differences in a condition has been established, this might in fact cause gender-biased assessments of individual patients in clinical practice.

Assessment of current prescribing practices using World Health Organization core drug use and complementary indicators in selected rural community pharmacies in Southern India

BACKGROUND

Due to the lack of clear, comprehensive, and rational drug policy, the production of pharmaceutical preparations in India is distorted for the most part. Indian markets are flooded with more than 70,000 formulations, compared to approximately 350 formulations listed in the World Health Organization (WHO) Essential Drug List. Studies have indicated that majority of prescriptions in India are of drugs of "doubtful efficacy." To promote rational drug use in developing countries, assessment of drug use patterns with the WHO drug use indicators is becoming increasingly necessary. The aim of this study was to assess the patterns of drug use by using WHO core drug use and complementary indicators.

METHODS

One thousand fifty-two patients were prospectively interviewed and their prescriptions analyzed according to WHO guideline five randomly selected busy community pharmacies in northern district of the State of Tamil Nadu, South India to analyze the WHO core drug use and complementary indicators using an investigator-administered data collection form. The main outcome measured is patterns of drug use measured using WHO core drug use and complementary indicators.

RESULTS

The data obtained showed that, out of total drugs prescribed (3936), only 2.5 % (100) drugs were prescribed by generic name. Mean number of drugs per encounter was 3.7. Use of antibiotics was 22 %, percentage of encounters with an injection was 7.2 %, and the percentage of drugs prescribed from formulary was 99.8 %.

CONCLUSIONS

Brand name prescribing is dominated even in rural India. There is a need to improve the availability of essential guidelines and key drugs in the stock in rural areas of India. Prescriptions studied were conforming to most indicators of WHO except the number of drugs prescribed & generic name prescription practice, which deviated. In India the healthcare is dominated by private practitioners at the primary level. Prescription practices of the individual community-based clinician needs consistent monitoring with respect to generic name prescribing habits as well as the number of drugs prescribed. The WHO drug use indicator guidelines need to be promoted amidst the primary care clinicians and should not be just limited to hospitals having a formulary. The data collected by this study can be used by policymakers to monitor and improve the prescribing and consumption of pharmaceutical products in Southern India.

Association of common mental disorder symptoms with health and healthcare factors among women in rural western India: results of a cross-sectional survey

OBJECTIVES

Information about common mental disorders (CMD) is needed to guide policy and clinical interventions in low-income and middle-income countries. This study's purpose was to characterise the association of CMD symptoms with 3 inter-related health and healthcare factors among women from rural western India based on a representative, cross-sectional survey.

SETTING

Surveys were conducted in the waiting area of various outpatient clinics at a tertiary care hospital and in 16 rural villages in the Anand district of Gujarat, India.

PARTICIPANTS

700 Gujarati-speaking women between the ages of 18-45 years who resided in the Anand district of Gujarat, India, were recruited in a quasi-randomised manner.

PRIMARY AND SECONDARY OUTCOMES MEASURES

CMD symptoms, ascertained using WHO's Self-Reporting Questionnaire-20 (SRQ-20), were associated with self-reported (1) number of healthcare visits in the prior year; (2) health status and (3) portion of yearly income expended on healthcare.

RESULTS

Data from 658 participants were used in this analysis; 19 surveys were excluded due to incompleteness, 18 surveys were excluded because the participants were visiting hospitalised patients and 5 surveys were classified as outliers. Overall, 155 (22·8%) participants screened positive for CMD symptoms (SRQ-20 score ≥8) with most (81.9%) not previously diagnosed despite contact with healthcare provider in the prior year. On adjusted analyses, screening positive for CMD symptoms was associated with worse category in self-reported health status (cumulative OR=9.39; 95% CI 5·97 to 14·76), higher portion of household income expended on healthcare (cumulative OR=2·31; 95% CL 1·52 to 3.52) and increased healthcare visits in the prior year (incidence rate ratio=1·24; 95% CI 1·07 to 1·44).

CONCLUSIONS

The high prevalence of potential CMD among women in rural India that is unrecognised and associated with adverse health and financial indicators highlights the individual and public health burden of CMD.

Carcinogenicity of psychotropic drugs: A systematic review of US Food and Drug Administration-required preclinical in vivo studies

OBJECTIVE

The US Food and Drug Administration approval process for psychotropic drugs requires safety studies of carcinogenicity in animals. These studies are consistently conducted and provide a database for assessment of potential biological risk of carcinogenicity in humans. This report is a systematic review of that database for psychotropic drugs.

METHOD

US Food and Drug Administration-approved registration data ('package inserts') were examined, where available, for all psychotropic drugs in the following classes: antidepressants, antipsychotics, benzodiazepines/sedative-hypnotics, amphetamines and anticonvulsants.

RESULTS

Overall, new generation (atypical) antipsychotics (90%, 9/10 agents) and anticonvulsants (85.7%, 6/7 agents) showed the highest evidence of carcinogenicity among psychotropic drugs classes assessed. Antidepressants (63.6%, 7/11) and benzodiazepines/sedative-hypnotics (70%, 7/10) were next, and stimulants (with the exception of methylphenidate) were last (25%, 1/4 agents). Overall, 71.4% of all drugs examined (30/42) showed evidence of carcinogenicity in 43.2% (38/88) of specific experimental studies.

CONCLUSIONS

US Food and Drug Administration-based analyses demonstrate that almost all atypical antipsychotics and anticonvulsants are carcinogenic in animals, as are the majority of antidepressants and benzodiazepines and methylphenidate. These animal-based results are not sufficient to draw definitive conclusions in humans, but they provide data that could be acknowledged in the informed consent process of clinical treatment.

Ideal Affect: Cultural Causes and Behavioral Consequences

Most research focuses on actual affect, or the affective states that people actually feel. In this article, I demonstrate the importance and utility of studying ideal affect, or the affective states that people ideally want to feel. First, I define ideal affect and describe the cultural causes and behavioral consequences of ideal affect. To illustrate these points, I compare American and East Asian cultures, which differ in their valuation of high-arousal positive affective states (e.g., excitement, enthusiasm) and low-arousal positive affective states (e.g., calm, peace-fulness). I then introduce affect valuation theory, which integrates ideal affect with current models of affect and emotion and, in doing so, provides a new framework for understanding how cultural and temperamental factors may shape affect and behavior.

Evaluation of Potential Drug-Drug Interactions with Antidepressants in Two Tertiary Care Hospitals

BACKGROUND

Limited resources of healthcare system and high use of antidepressants have raised some serious concerns regarding proper surveillance system of prescribed medicines. Not much literature is available from Pakistan regarding the potential drug-drug interactions (pDDIs) associated with antidepressants.

OBJECTIVE

The objective of this study was to assess the frequency of pDDIs associated with antidepressants, their severity, significance and their association with patient characteristics.

MATERIALS AND METHODS

A prospective, observational study was conducted in two major hospitals of Karachi for the period of three months. Patient profiles, medication charts, and physician notes were thoroughly reviewed to gather all the relevant information. Inclusion and exclusion criteria were set prior to data collection. The collected data was then analysed using Micromedex Drug-REAX System. Descriptive and binomial logistic regression analysis was used to express results.

RESULTS

Of 245 prescriptions reviewed, 141 prescriptions had at least one pDDI (57.5%). A total of 181 pDDIs were identified in prescription containing antidepressant. The ratio of pDDI per prescriptions was 0.78. 42.5% interactions were moderate in severity, 30% of interactions were rapid in onset, and 43% were considered as significant interactions. Polypharmacy (OR=3.41, p< 0.001) and presence of chronic problems (OR=2.14, p=0.002) were significantly associated with the occurrence of pDDIs. Citalopram and diclofenac (11.6%) was commonly prescribed interacting pair in this study.

CONCLUSION

The findings of this study recorded high frequency of antidepressants associated pDDIs. Our results confirm the significant association of polypharmacy with the occurrence of pDDIs with antidepressants. Future studies are warranted to establish these results by including hospitals in different parts of the country.

Qualitative study of the influence of antidepressants on the psychological health of patients on antiretroviral therapy in Uganda

The study set out to explore how HIV-positive individuals conceptualise and describe depression and its manifestation in their lives, and how this may change over time in the context of antiretroviral therapy (ART) and antidepressant treatment. We conducted in-depth interviews using a semi-structured interview guide with 26 adult HIV-positive clients receiving ART in Uganda. We asked the participants to describe their depression and its impact on their general health, physical functioning and psychological wellbeing, as well as the influences of receiving ART or antidepressant treatment. Although depressive experience among the patients was largely described in terms of criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR), some of the symptoms used to describe depression, such as 'thinking too much' or worrisome thoughts, did not fit into the DSM-IV criteria. The participants attributed their depression to news of the HIV diagnosis, a fear of dying, the potential socioeconomic consequences of their HIV infection on their family, ART side-effects and continued bad health. Their subjective reports indicated that the treatment of depression with antidepressants had made a positive impact on their general and psychological health. These findings highlight the need for models of HIV care that integrate mental health services and promote the diagnosis and treatment of depression in culturally sensitive ways so as to improve the quality of life and health outcomes for clients. However, keeping the particular study design in mind, these findings should be interpreted as preliminary.

Psicofármacos na Estratégia Saúde da Família: perfil de utilização, acesso e estratégias para a promoção do uso racional

O uso de psicofármacos está aumentando e no Brasil há poucos estudos investigando seu emprego pela população e na Atenção Primária à Saúde (APS). Este estudo buscou verificar a prevalência e o padrão de consumo por usuários de uma Unidade de Saúde da Família de Porto Alegre através de um delinemeanto observacional, descritivo, retrospectivo e de corte transversal. A amostra foi composta por usuários que retiraram receitas de medicamentos controlados e os dados coletados a partir do prontuário. Foram incluídos 329 usuários, com prevalência de utilização de psicofármacos de 7,30%, média de idade de 53,14 (DP = 18,58) anos e 72% de indivíduos do sexo feminino. A média de medicamentos e psicofármacos prescritos por usuário foi de 3,56 (DP = 2,36) e 1,66 (DP = 0,90), respectivamente. A classe mais utilizada foi a de antidepressivos, seguida de antiepiléticos, ansiolíticos e antipsicóticos. Faz-se necessário elaborar estratégias para melhorar o acesso, tratamento dos usuários e uso racional de psicofármacos, incluindo a revisão das listas de medicamentos essenciais e a capacitação dos profissionais da APS.

Using patients' narratives to reveal gender stereotypes among medical students

PURPOSE

Gender bias exists in patient treatment, and, like most people, health care providers harbor gender stereotypes. In this study, the authors examined the gender stereotypes that medical students hold about patients.

METHOD

In 2005, in Umeå, Sweden, the authors collected 81 narratives written by patients who had undergone cancer treatment; all information that might reveal the patients' gender was removed from the texts. Eighty-seven medical students read 40 or 41 narratives each, guessed the patient's gender, and explained their guess. The authors analyzed the students' explanations qualitatively and quantitatively to reveal the students' gender stereotypes and to determine whether those stereotypes had any predictive value for correctly guessing a patient's gender.

RESULTS

The students' explanations contained 21 categories of justifications, 12 of which were significantly associated with the students guessing one gender or the other. Only three categories successfully predicted a correct identification of gender; two categories were more often associated with incorrect guesses.

CONCLUSIONS

Medical students enter their training program with culturally shared stereotypes about male and female patients that could cause bias during their future careers as physicians. To prevent this, medical curricula must address gender stereotypes and their possible consequences. The impact of implicit stereotypes must be included in discussions about gender bias in health care.

Particular difficulties faced by GPs with young adults who will attempt suicide: a cross-sectional study

Background

Suicide is a major public health problem in young people. General Practitioners (GPs) play a central role in suicide prevention. However data about how physicians deal with suicidal youths are lacking. This study aims to compare young adult suicide attempters (from 18 to 39 years old) with older adults in a primary care setting.

Methods

A cross-sectional study was carried. All suicide attempts (N=270) reported to the French Sentinel surveillance System from 2009 to 2011 were considered. We conducted comparison of data on the last GP’s consultation and GPs’ management in the last three months between young adults and older adults.

Results

In comparison with older adults, young adults consulted their GP less frequently in the month preceding the suicidal attempt (40.9 vs. 64.6%, p=.01). During the last consultation prior to the suicidal attempt, they expressed suicidal ideas less frequently (11.3 vs. 21.9%, p=.03). In the year preceding the suicidal attempt, GPs identified depression significantly less often (42.0 vs. 63.4%, p=.001). In the preceding three months, GPs realized significantly less interventions: less psychological support (37.5 vs. 53.0%, p=.02), prescribed less antidepressants (28.6 vs. 54.8%, p<.0001) or psychotropic drugs (39.1 vs. 52.9%, p=.03) and made fewer attempts to refer to a mental health specialist (33.3 vs. 45.5%, p=.05).

Conclusion

With young adults who subsequently attempt suicide, GPs face particular difficulties compared to older adults, as a significant proportion of young adults were not seen in the previous six months, as GPs identified less depressions in the preceding year and were less active in managing in the preceding three months. Medical training and continuing medical education should include better instruction on challenges relative to addressing suicide risk in this particular population.

Factors associated with the type of psychotropic medications purchased for common mental disorders in the largest managed care organization in Israel

OBJECTIVE

To evaluate patient and physician characteristics associated with the type of psychotropic medications (anti-anxiety, antidepressant, or both) purchased.

METHODS

The Clalit Health Care Services is the largest managed care health fund in Israel, a country that employs a universal healthcare system. We randomly sampled 30,000 primary care patients over the age of 22 as of January, 2006.

RESULTS

Overall, 2,217 purchased either antidepressant or antianxiety medications at least once during the year 2006 and had no prior purchases during the last quarter of 2005. The majority (1,518; 68.4%) purchased only anti-anxiety medications and as many as 264 (12%) purchased both anti-anxiety and antidepressant medications. The remaining 435 (19.6%) patients purchased only antidepressant medications. Physician level characteristics explained only a small portion of the variance and, thus, were not included in further analysis. Several patient level characteristics, including age, somatic, and psychiatric diagnosis were associated with the purchase of different types of medications.

CONCLUSIONS

Contrary to clinical guidelines, the purchase of anti-anxiety medications is more prevalent than the purchase of antidepressant medications. In a managed care setting, patient characteristics have a greater role in determining purchasing patterns than provider characteristics; potentially, because of the managed care characteristics that actively guide the care provided to patients.

Religion and anxiety treatments in primary care patients

Earlier data suggested that religious physicians are less likely to refer to a psychiatrist or psychologist. This follow-up study measures how religious beliefs affect anxiety treatments in primary care. We surveyed US primary care physicians and psychiatrists using a vignette of a patient with anxiety symptoms. Physicians were asked how likely they were to recommend antianxiety medication, see the patient for counseling, refer to a psychiatrist, refer to a psychologist or licensed counselor, encourage meaningful relationships and activities, and encourage involvement in religious community. We experimentally varied symptom severity, whether the patient was Christian or Jewish, and whether she attended religious services. Physician attendance at religious services was assessed in the survey. The response rate was 896 out of 1427 primary care physicians and 312 out of 487 psychiatrists. Religious physicians were more likely to promote religious resources. There was no statistically significant difference between physicians' recommendations for religious and nonreligious patients. There was no statistically significant difference in religious and nonreligious physicians' referrals to a psychologist, licensed counselor, or psychiatrist. Ultimately, we did not find a difference in religious and nonreligious physicians' support for mental health referrals, however, religious physicians were more likely to encourage using religious resources.

"Caseness" for depression and anxiety in a depressed outpatient population: symptomatic outcome as a function of baseline diagnostic categories

OBJECTIVE

To examine the diagnostic status of patients enrolled in the Factors Influencing Depression Endpoints Research (FINDER) study and symptomatic outcomes and baseline characteristics associated with remission 6 months after commencing antidepressant therapy.

METHOD

Status of clinically diagnosed depressed patients was based on self-rated Hospital Anxiety and Depression Scale (HADS) scores. Five diagnostic categories were defined: noncaseness, mixed anxiety-depression (subthreshold depressive and anxious symptomatology), caseness for depression, caseness for anxiety, and caseness for comorbid anxiety-depression. Assessments included the Somatic Symptom Inventory and health-related quality of life (HRQoL) using the Medical Outcomes Study 36-item Short-Form Health Survey. Remission rates (based on HADS noncaseness for both depression and anxiety) and their associations with baseline characteristics were investigated. Patients were enrolled between May 2004 and September 2005.

RESULTS

Of the 3,353 patients enrolled, 66.4% met the HADS criteria for probable depressive disorder and 74.1% met the HADS criteria for probable anxiety disorder. Somatic symptom severity (painful and nonpainful) was highest and HRQoL was lowest in the comorbid anxiety-depression group. After 6 months, remission rates were 50.2% for caseness for depression, 40.4% for caseness for anxiety, and 40.6% for caseness for comorbid anxiety-depression. A lower number of previous depressive episodes, shorter current episode duration, lower painful and nonpainful somatic symptom scores, being married, a higher educational level, and working for pay were most consistently associated with higher remission rates.

CONCLUSIONS

Physicians do not always differentiate between anxiety and depressive symptoms when making a clinical diagnosis of depression. At baseline, most enrolled patients had significant emotional depressive and anxious symptoms, as well as significant nonpainful and painful somatic symptomatology, and these factors were associated with outcome.

Is drug utilization in Greece sex dependent? A population-based study

Despite scarce data pertaining to prescription drug sales in Greece, the lack of large-scale epidemiological studies has made it difficult to elaborate on putative differences regarding drug consumption patterns between the two sexes. Herein, we sought to investigate whether sex may have an impact on medication trends of the Greek population. The data reported are part of a survey conducted under the auspices of the National Center for Social Research. Information was collected from 2499 Athenian citizens. Probability of drug use was assessed through Pearson chi-square (χ(2) ) test and logistic regression was implemented to clarify whether sex or other socio-economic and morbidity factors may influence drug utilization. Women consumed more drugs as compared to men. Sex proved to be a differentiating factor influencing the use of analgesic/non-steroidal anti-inflammatory drugs, cardiovascular, anxiolytic and antidepressant drugs, as well as drugs for the treatment of thyroid diseases and osteoporosis. Present results further implicate other socio-economic factors (e.g. education, employment and financial status) in the harnessing of drug use in Greece. To the best of our knowledge, this is the largest pharmacoepidemiological study to report that Greek women consume more drugs and present different medication patterns, as compared to men. Further research is considered imperative in order for the awareness of prescribers, policy-makers and the general public on this sensitive matter to be increased.

Clinically significant psychotropic drug-drug interactions in the primary care setting

In recent years, the growing numbers of patients seeking care for a wide range of psychiatric illnesses in the primary care setting has resulted in an increase in the number of psychotropic medications prescribed. Along with the increased utilization of psychotropic medications, considerable variability is noted in the prescribing patterns of primary care providers and psychiatrists. Because psychiatric patients also suffer from a number of additional medical comorbidities, the increased utilization of psychotropic medications presents an elevated risk of clinically significant drug interactions in these patients. While life-threatening drug interactions are rare, clinically significant drug interactions impacting drug response or appearance of serious adverse drug reactions have been documented and can impact long-term outcomes. Additionally, the impact of genetic variability on the psychotropic drug's pharmacodynamics and/or pharmacokinetics may further complicate drug therapy. Increased awareness of clinically relevant psychotropic drug interactions can aid clinicians to achieve optimal therapeutic outcomes in patients in the primary care setting.

[Policies and innovation in mental healthcare: limits to decoupling from the performance of the SUS]

We studied Brazilian policies on mental health with respect to normative, supply and demand and financing aspects. We concluded that the sustainability of innovations in psychiatric reform depends on enhanced financing and integration with primary care community services, on the overall performance of SUS and the reduction of autonomous and exclusive services in primary care. There is high and rising pressure in demand for services measured in DALY and the incidence of disease. The reduction observed in psychiatric beds was accompanied by the systemic reduction, though with selective reduction for psychiatric hospitalizations. CAPS services have institutional limits due to the model adopted of direct public administration and local government capacity. Secondary data available show that: (i) SUS has a virtual monopoly on general outpatient and hospital services; (ii) mental health specialists belong mostly to SUS; (iii) most mental health services are outpatient services; (iv) few CAPS have day-bed services available; and (v) there is reduced federal financing for these innovations.

Psychotropic prescribing in Catalonia: results from an epidemiological study

BACKGROUND

Mental disorders (MDs) are mainly treated in primary care (PC), where psychotropic drug (PSD) prescribing is highly prevalent. Prescription of PSD is associated with clinical and non-clinical factors.

PURPOSE

To describe the patterns of PSD prescribing over a 12-month period and to determine the factors associated with this in a PC population.

METHODS

Cross-sectional study. Data were collected on 3815 patients, via patient interview, on sociodemographics and MDs [Diagnostic and Statistical Manual of Mental Disorders (DSM-IV criteria)]. Computerized records provided data on PSD prescribing. Multilevel logistic regressions assessed the factors that influence prescribing.

RESULTS

Thirty-four per cent of PC patients were prescribed PSDs >12 months, with anxiolytics being the most commonly prescribed (22%). Fifty-three per cent of patients with any MD in this 12-month period were prescribed PSDs; however, 25% of patients without any of these disorders were also prescribed these medications. Higher rates of prescribing were associated with female gender, older age, presence of MD, being a househusband/housewife, consulting about psychological problems, increasing number of consultations and higher self-perceived disability. PSDs were less likely to be prescribed to patients born outside Spain and those consulting about physical conditions. PSD prescribing was higher in patients previously married and antipsychotic prescribing was higher in patients never married. No statistically significant associations were found between PSD prescription and education.

CONCLUSIONS

PSD prescribing rates are high in Catalonia and are associated with a number of clinical and non-clinical factors. A significant proportion of patients are receiving these drugs in the absence of MD. These findings need to be considered when prescribing in PC.

Depression: major problem for public health

The aim of this Editorial is to discuss depression as an important disorder for public health. The literature regarding epidemiology, consequences, adequacy of service delivery and prevention of depression is reviewed. Depression is a common disorder with high lifetime rates, particularly in women, and those experiencing social adversity. It is a major cause of disability, and causes death both by suicide and due to raised rates of physical disorders. Many cases are undiagnosed and treatment is often inadequate. Primary prevention is not yet easily feasible but secondary prevention by earlier recognition, public and professional education, can produce benefits. There is a need for public health programmes aimed at improving recognition, treatment, and reducing consequences.

Initiation of antipsychotic treatment by general practitioners. a case-control study

RATIONALE, AIMS AND OBJECTIVES

Antipsychotics are approved treatment for severe conditions and have serious side effects. Antipsychotics are often prescribed off-label. Although a substantial proportion of antipsychotics are prescribed in primary care, it is largely unknown what motivates the general practitioner (GP) to initiate antipsychotic treatment. Therefore, we sought to examine the relation between pre-defined, licensed as well as off-label, reasons for antipsychotic treatment and the initiation of this treatment by the GP as well as report registration and incidence of antipsychotic treatment in general practice.

METHODS

In a case-control study, 723 patients selected from an electronic database and with a new antipsychotic prescription were compared with 3615 controls receiving any other new prescription. Using logistic regression, six pre-defined categories of International Classification of Primary Care (ICPC) codes ('psychosis', 'depression and anxiety', 'sleeping disorders', 'acute stress and surmenage', 'dementia' and 'somatic indications') were associated with initiating antipsychotic treatment.

RESULTS

All, including off-label, categories were significantly related to initiating antipsychotic treatment. The incidence of initiating antipsychotic therapy was 1.28 per 1000 persons per year (95% confidence interval: 1.09, 1.48). GPs registered an ICPC code in 50% and prescribed typical antipsychotics in 90% of the cases. Prescription of atypical antipsychotics increased almost threefold over the study period.

CONCLUSIONS

The results suggest that GPs prescribe antipsychotics off-label. Despite serious side effects and relatively infrequent occurrence in Dutch general practices, GPs seem imprecise in underpinning and registrating the initiation of antipsychotic treatment. GPs increasingly prescribe atypical antipsychotics although the prescription of typical antipsychotics still dominates.

Beliefs and attitudes of French family practitioners toward depression: the impact of training in mental health

OBJECTIVE

To study, in a sample of French Family Practitioners (FPs), beliefs and attitudes toward depression and how they vary according to training received in mental health.

METHODS

The Depression Attitude Questionnaire (DAQ) was completed by 468 FPs from all regions of France, recruited by pharmaceutical company representatives to attend focus groups on the management of depression in general practice.

RESULTS

A three-factor model was derived from the DAQ, accounting for 37.7% of the total variance. The correlations between individual items of each component varied from 0.4 to 0.65, with an overall internal consistency of 0.47 (Cronbach's alpha). FPs had an overall neutral position on component 1, professional ease, a positive view on the origins of depression and its amenability to change (component 2), and a belief in the necessity of medication and the benefit of antidepressant therapy (component 3). Training in mental health, specifically through continuing medical education and postgraduate psychiatric hospital training, was significantly and positively associated with both professional ease and a medication approach to treating depression.

CONCLUSION

This study is the first description of the beliefs and attitudes of French FPs toward depression using a standardized measure, the DAQ, despite the instrument's limited psychometric properties. It shows the positive effect of training in mental health on attitudes toward depression.

Effectiveness of an intervention led by lay health counsellors for depressive and anxiety disorders in primary care in Goa, India (MANAS): a cluster randomised controlled trial

BACKGROUND

Depression and anxiety disorders are common mental disorders worldwide. The MANAS trial aimed to test the effectiveness of an intervention led by lay health counsellors in primary care settings to improve outcomes of people with these disorders.

METHODS

In this cluster randomised trial, primary care facilities in Goa, India, were assigned (1:1) by computer-generated randomised sequence to intervention or control (enhanced usual care) groups. All adults who screened positive for common mental disorders were eligible. The collaborative stepped-care intervention offered case management and psychosocial interventions, provided by a trained lay health counsellor, supplemented by antidepressant drugs by the primary care physician and supervision by a mental health specialist. The research assessor was masked. The primary outcome was recovery from common mental disorders as defined by the International Statistical Classification of Diseases and Related Health Problems-10th revision (ICD-10) at 6 months. This study is registered with ClinicalTrials.gov, number NCT00446407.

FINDINGS

24 study clusters, with an equal proportion of public and private facilities, were randomised equally between groups. 1160 of 1360 (85%) patients in the intervention group and 1269 of 1436 (88%) in the control group completed the outcome assessment. Patients with ICD-10-confirmed common mental disorders in the intervention group were more likely to have recovered at 6 months than were those in the control group (n=620 [65·0%] vs 553 [52·9%]; risk ratio 1·22, 95% CI 1·00-1·47; risk difference=12·1%, 95% CI 1·6%-22·5%). The intervention had strong evidence of an effect in public facility attenders (369 [65·9%] vs 267 [42·5%], risk ratio 1·55, 95% CI 1·02-2·35) but no evidence for an effect in private facility attenders (251 [64·1%] vs 286 [65·9%], risk ratio 0·95, 0·74-1·22). There were three deaths and four suicide attempts in the collaborative stepped-care group and six deaths and six suicide attempts in the enhanced usual care group. None of the deaths were from suicide.

INTERPRETATION

A trained lay counsellor-led collaborative care intervention can lead to an improvement in recovery from CMD among patients attending public primary care facilities.

Psychotropic drug use among women exposed to intimate partner violence: A population-based study

Aims: To investigate psychotropic drug use among women ever exposed to intimate partner violence (IPV) in relation to mental distress and sociodemographic, lifestyle and somatic health characteristics, and to assess whether drug use differed for physical and/or sexual violence compared with psychological abuse alone. Methods: Cross-sectional data from women aged 30—60 years were drawn from self-reported questionnaires in the Oslo Health study 2000—2001. Women reporting hypnotic, anxiolytic and/or antidepressant drug use in the previous four weeks were defined as users. Differences in psychotropic drug use by IPV exposure were examined by logistic regression analyses. Results: In total, 880 (14%) of 6,471 included women reported ever experiencing IPV; 494 (8%) reported physical and/or sexual IPV, and 386 (6%) reported psychological IPV alone. Physical and/or sexual IPV was significantly associated with use of all psychotropic drugs: hypnotics (odds ratio (OR) 2.28; 95% confidence interval (95% CI), 1.73—3.00); anxiolytics (OR 3.29; 95% CI, 2.43—4.44); and antidepressants (OR 2.72; 95% CI, 1.97—3.76). The associations remained significant for anxiolytics (OR 1.67; 95% CI, 1.14—2.45) and antidepressants (OR 1.50; 95% CI, 1.02—2.19) after adjusting for mental distress, sociodemographic, lifestyle and somatic health characteristics. Psychological IPV alone was associated with use of anxiolytics (OR 1.81; 95% CI, 1.20—2.75) and antidepressants (OR 2.38; 95% CI, 1.64—3.45). After adjustments the association persisted for use of antidepressants only (OR 1.64; 95% CI, 1.05—2.55). Conclusions: Women exposed to IPV were more likely to report use of psychotropic drugs, even after adjusting for mental distress. The study indicates that exposure to IPV; including psychological abuse should be evaluated as a possible source of distress when psychotropic drug treatment is considered.

Time to depression treatment in primary care among HIV-infected and uninfected veterans

BACKGROUND

Multiple factors, including patient characteristics, competing demands, and clinic type, impact delivery of depression treatment in primary care.

OBJECTIVE

Assess whether depression severity and HIV serostatus have a differential effect on time to depression treatment among depressed patients receiving primary care at Infectious Disease or General Medicine clinics.

DESIGN

Multicenter prospective cohort, (Veterans Aging Cohort Study), comparing HIV-infected to uninfected patients.

PARTICIPANTS AND MEASURES

The total cohort consisted of 3,239 HIV-infected and 3,227 uninfected patients. Study inclusion criteria were untreated depressive symptoms, based on a Patient Health Questionnaire (PHQ-9) score of greater than 9, and no antidepressants or mental health visits in the 90 days prior to PHQ-9 assessment. Treatment was defined as antidepressant receipt or mental health visit within 90 days following PHQ-9 assessment. Depression severity based on PHQ-9 scores was defined as mild-moderate (greater than 9 to 19) and severe (20 or greater). Kaplan-Meier curves were used to estimate time to treatment by depression severity and HIV serostatus. Cox proportional hazards methods adjusted for covariates were used.

KEY RESULTS

Overall, 718 (11%) of the cohort met inclusion criteria, 258 (36%) of whom received treatment. Median time to treatment was 7 days [95% confidence interval (CI) = 4, 13] and was shortest for severely depressed HIV-infected patients (0.5 days; 95% CI = 0.5, 6, p = 0.04). Compared to mildly-moderately depressed uninfected patients, severely depressed HIV-infected patients were significantly more likely to receive treatment [adjusted hazard ratio (HR) 1.67, 95% CI = 1.07, 2.60), whereas mildly-moderately depressed HIV-infected patients (adjusted HR 1.10, 95% CI = 0.79, 1.52) and severely depressed uninfected patients (adjusted HR 0.93, 95% CI = 0.60, 1.44) were not.

CONCLUSIONS

In this large cohort, time to primary care treatment of depression was shortest among severely depressed HIV-infected patients. Regardless of HIV serostatus, if depression was not treated on the assessment day, then it was unlikely to be treated within a 90-day period, leading to the majority of depression being untreated.

Fatores associados ao uso de psicofármacos em idosos asilados

INTRODUÇÃO: As instituições de longa permanência para idosos (ILPI) apresentam altas prevalências de internados em uso de psicofármacos para o controle de distúrbios comportamentais. Há, porém, poucos estudos brasileiros sobre esse aspecto de abordagem terapêutica em ILPI. OBJETIVO: Avaliar os fatores associados ao uso de psicofármacos em pacientes idosos institucionalizados. MÉTODOS: Foi realizado estudo transversal e retrospectivo por meio de análise de prontuários de todos os idosos (60 anos ou mais) internados em um ILPI, independentemente das doenças apresentadas. Regressão logística foi realizada para verificar os fatores associados ao uso de psicofármacos na instituição. RESULTADOS: Foram avaliados 209 pacientes (73,2% mulheres), predominantemente portadores de síndromes demenciais, sequelas de acidentes vasculares cerebrais ou de traumas de crânio e hipertensão arterial sistêmica. Os psicofármacos estavam prescritos para 123 internados (58,9% do total), principalmente neurolépticos e antidepressivos. Após a regressão logística, encontrou-se associação entre a prescrição de neurolépticos e demência (p = 0,000), enquanto que o uso de antidepressivos esteve associado a maior número de medicamentos (p = 0,004) e presença de depressão (p = 0,000). O uso de psicofármacos em geral esteve fortemente associado com depressão (p = 0,000), presença de demência (p = 0,006) e presença de doenças psiquiátricas (p = 0,02). Não houve associação com as variáveis sexo, funcionalidade e idade. CONCLUSÃO: Há alto consumo de psicofármacos em ILPI. A associação destes com polifarmácia e depressão é significativa, e os portadores de demência foram os que mais fizeram uso dos neurolépticos. Fatores como idade e sexo, normalmente relevantes em pacientes ambulatoriais, não apresentaram associação em institucionalizados.

Problem-solving treatment and coping styles in primary care for minor depression

Research was undertaken to compare problem-solving treatment for primary care (PST-PC) with usual care for minor depression and to examine whether treatment effectiveness was moderated by coping style. PST-PC is a 6-session, manual-based, psychosocial skills intervention. A randomized controlled trial was conducted in 2 academic, primary care clinics. Those subjects who were eligible were randomized (N = 151), and 107 subjects completed treatment (57 PST-PC, 50 usual care) and a 35-week follow-up. Analysis with linear mixed modeling revealed significant effects of treatment and coping, such that those in PST-PC improved at a faster rate and those initially high in avoidant coping were significantly more likely to have sustained benefit from PST-PC.

Gender bias in medicine

Gender bias has implications in the treatment of both male and female patients and it is important to take into consideration in most fields of medical research, clinical practice and education. Gender blindness and stereotyped preconceptions about men and women are identified as key causes to gender bias. However, exaggeration of observed sex and gender differences can also lead to bias. This article will examine the phenomenon of gender bias in medicine, present useful concepts and models for the understanding of bias, and outline areas of interest for further research.

Educating and informing patients receiving psychopharmacological medications: are family physicians in Pakistan up to the task?

Introduction

Studies have shown a high prevalence of psychiatric illnesses among patients in primary health care settings. Family physicians have a fundamental role in managing psychiatric illness with psychopharmacological medications. Providing information about the disease, its management and the potential adverse effects of the medications is an important part of the management of mental illnesses. Our objective was to determine if patients who were prescribed psychopharmacological drugs by family physicians at a community health center in Karachi, Pakistan were provided adequate education about their disease and its management.

Methods

A cross-sectional study was conducted at the Community Health Centre (CHC), Aga Khan University Hospital Karachi, Pakistan. Details about the prescriptions and patient education were acquired from the patients after their consultations.

Results

A total of 354 adult patients were interviewed during 3 days. Among them, 73 (20.6%) were prescribed psychopharmacological medications. Among patients receiving psychopharmacological medicines, 37 (50.7%) did not know their diagnosis; 50 (68.5%) were unaware of the disease process; 52 (71.2%) were unaware of alternative treatments; 63 (86.3%) were not cautioned about the potential adverse effects of the drugs; 24 (32.9%) were unaware of the duration of treatment and in 60 (82.2%) of the participants an appropriate referral had not been discussed. For all aspects of education, patients prescribed psychopharmacological medications knew less as compared to those patients that were prescribed other medications.

Discussion

The practice of imparting information to patients who receive psychopharmacological medications seems to be inadequate in Pakistan. We have hypothesized about the possible reasons for our findings, and identified a need for further research to determine the cause for such findings and to address them accordingly. At the same time there is a need to educate family physicians in Pakistan about the special importance of providing adequate information to such patients.

Factors associated with antidepressant, anxiolytic and hypnotic use over 17 years in a national cohort

BACKGROUND

In the general population, most individuals with mental disorders are not treated with psychotropic medications. The objective of this study was to identify factors associated with psychotropic medication use over a 17 year period in a birth cohort.

METHOD

Members of the 1946 British birth cohort (n=2,928 in 1999) reported psychotropic medication use in 1982 at age 36, in 1989 at age 43, and in 1999 at age 53. At each of the three time points, several factors were investigated for their association with antidepressant, anxiolytic or hypnotic medication use.

RESULTS

After adjusting for severity of symptoms of depression and anxiety, clinical factors such as suicidal ideation, sleep difficulty and poor physical health were strongly associated with antidepressant, anxiolytic or hypnotic medication use in 1982 and 1989, but not in 1999. Non-clinical factors were infrequently associated with antidepressant, anxiolytic or hypnotic medication use in 1982 and 1989 after adjusting for severity of symptoms, however several non-clinical factors were associated with antidepressant, anxiolytic or hypnotic medication use in 1999 including being female (OR=1.4, 95% CI: 1.0, 1.9), unemployment (OR=2.9, 95% CI: 2.1, 4.1), living alone (OR=2.6, 95% CI: 1.7, 3.9), and being divorced, separated or widowed (OR=1.5, 95% CI: 1.1, 2.3).

LIMITATIONS

Data were not available on help-seeking behaviour.

CONCLUSIONS

Treatment of mental disorder with psychotropic medications is strongly associated with clinical factors. However, non-clinical factors continue to be significant, and may influence both treatment-seeking and prescribing behaviour.

Off-label utilization of antidepressants

While antidepressant prescription rules are established for approved indications by large-scale studies, off-label utilization naturally often lacks the validation by large scientific databases, and is at its best based on expert consensus. The aim of the present survey was to study the prescription habits of hospital psychiatrists with regard to antidepressants, comparing patients treated for depressions and anxiety disorder with patients receiving off-label antidepressant treatment.

METHODS

Data on drug use for this study were based on 6 reference days from April 1999 to November 2001 in the 98-bed psychiatric hospital of the University of Lausanne, Switzerland. The drug prescriptions of 174 patients were assessed.

RESULTS

Whereas the diagnosis did not influence the choice between newer or older antidepressants, patients presenting an anxiety disorder were 4.5 times more likely (p<0.05) and patients with other diagnoses 8 times more likely (p<0.001) to receive an antipsychotic comedication compared to patients whose primary diagnosis was a depressive disorder. Also, patients receiving concomitantly a nonbenzodiazepine hypnotic were less likely to be prescribed an older antidepressant (p<0.05). While patients with anxiety disorder and those with major depression received their antidepressants at comparable doses, patients with an off-label indication were treated preferentially with lower doses.

CONCLUSIONS

The results of this survey suggest, that the prescribing hospital psychiatrists developed preferences with regard to the choice of the antidepressant class, which they then used for both registered and off-label indications. They then seemed to adapt the dose and the comedication according to the diagnosis, confirming the initial study hypothesis.

Prevalence of DSM-IV major depression among Spanish university students

OBJECTIVE

The authors' purpose in this study was to estimate prevalence and correlates of Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV), major depressive episodes (MDEs) among Spanish university students.

PARTICIPANTS AND METHODS

In October and November 2004, interviewers administered a screening tool to a sample of 554 students aged 18-34 years (65.9% women).

RESULTS

The prevalence of MDEs was 8.7% (95% confidence interval = 6.5%-11.3%). The most common symptoms were depressed mood (81.3%) and altered sleep (79.2%). MDEs were more prevalent among women than men (p < .05). The mean number of previous episodes of depression among currently depressed students with previous episodes was 2.2 (SD = 1.4). Of depressed students, 0.6% had considered suicide and 0.2% had attempted suicide.

CONCLUSIONS

Depression was highly prevalent among university students. The results suggest the need to develop some type of program or service for university students with the aim of preventing depression and improving their adaptation to university life.

The 'European Alliance Against Depression (EAAD)': a multifaceted, community-based action programme against depression and suicidality

Action programmes fostering partnerships and bringing together regional and national authorities to promote the care of depressed patients are urgently needed. In 2001 the 'Nuremberg Alliance Against Depression' was initiated as a community-based model project within the large-scale 'German Research Network on Depression and Suicidality' (Kompetenznetz 'Depression, Suizidalität'). The 'Nuremberg Alliance Against Depression' was an action programme, conducted in the city of Nuremberg (500,000 inhabitants) in 2001/2002, addressing four intervention levels (Hegerl et al. Psychol Med 2006;36:1225). Based on the positive results of the Nuremberg project (a significant reduction of suicidal behaviour by more than 20%) 18 international partners representing 16 different European countries established the 'European Alliance Against Depression' (EAAD) in 2004. Based on the four-level approach of the Nuremberg project, all regional partners initiated respective regional intervention programmes addressing depression and suicidality. Evaluation of the activities takes place on regional and international levels. This paper gives a brief overview of the background for and experiences with the EAAD. It describes the components of the programme, provides the rationale for the intervention and outlines the current status of the project. The aim of the paper is to disseminate information about the programme's potential to reduce suicidal behaviour and to provide examples of how European community-based 'best practice' models for improving the care of depressed patients and suicidal persons can be implemented using a bottom-up approach. EAAD is mentioned by the European commission as a best practice example within the Green Paper 'Improving the mental health of the population: Towards a strategy on mental health for the European Union' (European Commission 2005).

Temporary employment and antidepressant medication: a register linkage study

Evidence on the association between temporary employment and mental health is mixed. This study examined associations of temporary employment with register-based antidepressant medication by type and length of temporary job contract and socioeconomic position. Antidepressant prescriptions (1998-2002) were linked to register data for 17,071 men and 48,137 women in 10 Finnish municipalities. Repeated measures analyses over time were adjusted for age, socioeconomic position, and calendar year. After adjustments, temporary employment with a job contract more than 6 months was associated with odds ratio (OR) of 1.18 (95% confidence interval CI 1.03-1.37) for antidepressant use in men and 0.99 (0.93-1.06) in women. Among temporary employees with a job contract of 6 months or less the corresponding odds ratio was higher (OR 1.43, 95% CI 1.19-1.73 in men, OR 1.18, 95% CI 1.09-1.28 in women). Long-term unemployed who were in short-term government-subsidised temporary employment had the highest odds of antidepressant use (OR 1.57, 95% CI 1.23-2.02 in men, OR 1.38, 95% CI 1.20-1.59 in women). During the study period, increase in the prevalence of antidepressant medication was more rapid among women in government-subsidised temporary employment than among permanently employed women. Among men, the association between temporary employment and antidepressant use was stronger within lower grade occupations. The results suggest that using antidepressants is more pronounced when temporary employment is unstable.

Integrating evidence-based treatments for common mental disorders in routine primary care: feasibility and acceptability of the MANAS intervention in Goa, India

Common mental disorders, such as depression and anxiety, pose a major public health burden in developing countries. Although these disorders are thought to be best managed in primary care settings, there is a dearth of evidence about how this can be achieved in low resource settings. The MANAS project is an attempt to integrate an evidence based package of treatments into routine public and private primary care settings in Goa, India. Before initiating the trial, we carried out extensive preparatory work, over a period of 15 months, to examine the feasibility and acceptability of the planned intervention. This paper describes the systematic development and evaluation of the intervention through this preparatory phase. The preparatory stage, which was implemented in three phases, utilized quantitative and qualitative methods to inform our understanding of the potential problems and possible solutions in implementing the trial and led to critical modifications of the original intervention plan. Investing in systematic formative work prior to conducting expensive trials of the effectiveness of complex interventions is a useful exercise which potentially improves the likelihood of a positive result of such trials.

Improving the outcomes of primary care attenders with common mental disorders in developing countries: a cluster randomized controlled trial of a collaborative stepped care intervention in Goa, India

BACKGROUND AND OBJECTIVE

Common mental disorders (CMD) are a leading global burden of disease. Up to 30% of primary care attenders suffer from these disorders but most do not receive evidence-based drug or psychological treatments. There are no trials of interventions which attempt to integrate these treatments into routine primary care in developing countries. The aims of this trial (the MANAS Project) are to evaluate the clinical and cost-effectiveness of a collaborative stepped-care intervention for the treatment of CMD in India.

STUDY DESIGN

A cluster randomized controlled trial will be implemented in the state of Goa, on the west coast of India. Twenty-four primary care facilities, 12 from the government sector and 12 from the private sector, will be enrolled in two consecutive phases. For each sector, facilities will be randomly allocated within strata defined by urban/rural location, population size and presence of a visiting psychiatrist. Facilities will be randomly allocated to receive the collaborative stepped care intervention or the enhanced usual care control intervention. Both arms share two components of the intervention, viz., routine screening, and in the government clinics provision of antidepressants. In addition, the collaborative stepped care arm also provides a range of psychosocial treatments delivered by a specially trained Health Counselor, and supervision by a visiting Psychiatrist. A total of 3600 primary care attenders who are detected to suffer from a CMD based on a validated screening questionnaire will be recruited. The primary outcome is the proportion of subjects who recover from an ICD10 defined CMD at baseline by 6 months. Additional endpoints at 2 and 12 months will assess the speed and sustainability of achieving the primary outcomes. Other outcomes will include recovery from ICD10 defined depression and incidence of ICD-10 among individuals who were sub-threshold cases at baseline. Economic and disability outcomes will be assessed to estimate incremental cost-effectiveness ratios.

IMPLICATIONS

This will be the first trial of the effectiveness of a complex intervention aiming to integrate efficacious treatments for CMD into routine primary care in a developing country. If effective, its findings will have relevance to policy makers who wish to scale up treatments for CMD in primary care across the world, but mostly in those countries where specialist mental health services are few.

STUDY REGISTRATION

The MANAS project is registered through the National Institutes of Health sponsored clinical trials registry and has been assigned the identifier: NCT00446407.

Co-prescription of antidepressants with other psychotropics: Distinct profile of escitalopram

Objective. Recent meta-analyses have argued that there are no clinically significant differences between various selective serotonin reuptake inhibitors (SSRIs) or between SSRIs and other antidepressants. Analysis of large-scale national prescription databases may offer a unique opportunity to see whether this premise holds true in actual practice. National databases however, should be viewed with caution as they reveal only limited information about efficacy and tolerability. Methods. The number of antidepressants prescribed annually (October 2004 to September 2005), as well as the class of drug and the use of any additional psychotropics were obtained from the Israeli subsidiary of Intercontinental Marketing Services (IMS) Health. Results. During the 12-month study period there were 2,107,763 prescriptions of antidepressants reported by IMS in Israel. Compared to other drug classes, the SSRIs were used significantly more often as a sole therapy (chi-square=1343, df=3, P<0.0001). Of the SSRIs, escitalopram was the most frequently prescribed (79%) as monotherapy, followed by fluoxetine with 72% and <70% for the other SSRIs. The most frequently prescribed additional psychotropic was a benzodiazepine, in the range of 38 to nearly 50%. Conclusion. Antidepressants vary significantly in their use as a single ("monotherapy") drug. The use of additional psychotropics could reflect either the presence of symptoms not well covered by a particular antidepressant or for addressing side effects particular to a certain class of antidepressants.The premise that all SSRIs are equal is not reflected in this current examination.

Different acute tolerance development to EEG, psychomotor performance and subjective assessment effects after two intermittent oral doses of alprazolam in healthy volunteers

BACKGROUND/AIMS

Benzodiazepines (BZDs) are the most effective of the psychotropic drugs in the treatment of anxiety disorders. Tolerance has been reported for the majority of BZDs after chronic administration. However, little attention has been paid to the possibility that tolerance might be present after the intermittent oral administration of BZDs. The objectives of the present study were to assess tolerance development after the administration of two intermittent single oral doses of alprazolam given 15 days apart in healthy volunteers, and to compare the results obtained using measures from different domains: neurophysiological, psychomotor and subjective.

METHODS

Twenty-four healthy volunteers received 2 mg of alprazolam orally on two experimental days, 15 days apart. Plasma concentrations and pharmacodynamics (PD) were assessed before drug intake and at different times in the following 24 h. PD was assessed through EEG (relative alpha and relative beta-1 activities), cancellation task (total and correct number of responses) and visual analogue scales (activity and drowsiness).

RESULTS

No differences were observed in the PKs of alprazolam between occasions. A proteresis was present in both administrations for impairments of psychomotor performance and relative beta-1 activity, whereas it was present only after the second administration for subjective assessments and relative alpha activity. The proteresis on the second occasion was higher than on the first one.

CONCLUSIONS

The administration of two single oral doses of alprazolam, 2 weeks apart in healthy volunteers, yielded the same PKs on both occasions, but significant changes were observed in the PD profile. Acute tolerance was observed after the second administration. Two patterns of acute tolerance development were obtained: (1) impairments of psychomotor performance and relative beta-1 activity, and (2) subjective assessments and relative alpha activity.

Use of the PRIME-MD Patient Health Questionnaire for estimating the prevalence of psychiatric disorders in French primary care: comparison with family practitioner estimates and relationship to psychotropic medication use

OBJECTIVES

The objectives of this study were to establish provisional psychiatric diagnoses using the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire (PHQ) and to describe family practitioner (FP) case recognition, survey-day prescription of anxiolytic and antidepressant medications and overall consumption rates (medication use).

METHODS

Between October 2003 and April 2004, 1151 consecutive patients (> or = 18 years old) of 46 FPs practicing in and around the city of Montpellier, France, completed the PHQ. During the consultation, FPs rated the severity of any psychiatric disorder.

RESULTS

PHQ prevalence rates (FP case recognition percentages are given in parentheses) were as follows: 10.9% (36%) for probable alcohol abuse/dependence; 11.3% (40%) for somatoform disorder; 9.1% (75%) for major depression; 7.4% (42%) for other depressive disorders; 7.5% (69%) for panic disorder; and 6% (69%) for other anxiety disorders. The prescription rate for all study patients was 11.3%, ranging from 6.2% for those without a PHQ disorder to 30.3% for those with a PHQ diagnosis of anxiety or depression to 48.2% for FP-recognized cases. The estimated survey-day consumption rate for these medications was 19.4%.

CONCLUSIONS

High consumption of anxiolytic and antidepressant medications in France is confirmed but not explained either by higher prevalence rates of psychiatric disorders as compared with other locations or by unusually high survey-day prescription rates. A possible explanation would be the organization of the French health care system, which has multiple sources for obtaining medication.

Psychiatric treatment in primary care patients with anxiety disorders: a comparison of care received from primary care providers and psychiatrists

OBJECTIVE

This study examined psychiatric treatment received by primary care patients with anxiety disorders and compared treatment received from primary care physicians and from psychiatrists.

METHOD

Primary care patients at 15 sites were screened for anxiety symptoms. Those screening positive were interviewed to assess for anxiety disorders. Information on psychiatric treatment received and provider of pharmacological treatment were collected.

RESULTS

Of 539 primary care participants with at least one anxiety disorder, almost half (47.3%) were untreated. Nearly 21% were receiving medication only for psychiatric problems, 7.2% were receiving psychotherapy alone, and 24.5% were receiving both medication and psychotherapy. Patients receiving psychopharmacological treatment received similar medications, often at similar dosages, regardless of whether their prescriber was a primary care physician or a psychiatrist. One exception was that patients were less likely to be taking benzodiazepines if their provider was a primary care physician. Those receiving medications from a primary care provider were also less likely to be receiving psychotherapy. Overall, patients with more functional impairment, more severe symptoms, and comorbid major depression were more likely to receive mental health treatment. Members of racial/ethnic minority groups were less likely to be treated. Frequently endorsed reasons for not receiving pharmacological treatment were that the primary care physician did not recommend it and the patient did not believe in taking medication for emotional problems.

CONCLUSIONS

Nearly half the primary care patients with anxiety disorders were not treated. However, when they were treated, the care received from primary care physicians and psychiatrists was relatively similar.

Prioritizing health problems in women in developing countries: comparing the financial burden of reproductive tract infections, anaemia and depressive disorders in a community survey in India

OBJECTIVES

To compare the health care and opportunity costs of three common health problems [depressive disorders, reproductive tract infections (RTIs) and anaemia] affecting women and their associated risks of catastrophic health expenditure (defined a priori as out-of-pocket expenditure on health care exceeding 10% of the total monthly household income).

METHODS

Cross-sectional survey of 2494 women who consented to participate, from a randomly selected sample of 3000 women aged 18-50, living in the catchment area of a primary health centre in Goa, India. Depressive disorders were diagnosed with the Revised Clinical Interview Schedule; anaemia on the basis of a fingerprick sample of blood using the Haemocue system; and RTI using PCR, culture and microscopy with vaginal or urine specimens. Economic consequences were measured using the Costs of Illness Schedule and the WHO Disability Assessment Schedule. Health provision costs were calculated using previously derived unit costs for services for the main types of health care provider.

RESULTS

Catastrophic health expenditure, defined a priori as >10% of total household income spent out of pocket on health in the previous month, was reported by 138 women (5.5%; CI: 4.7-6.5%); they were more likely to report economic difficulties, such as having gone hungry in the past 3 months because of lack of money (OR 1.99, CI 1.1-3.6, P = 0.02). Only depressive disorder was associated with significantly higher health care costs, lost time costs and risk of catastrophic health expenditure (OR 2.66, CI 1.6-4.4, P < 0.001, after adjustment for possible sociodemographic confounders and other physical health problems). There was a linear association between the psychological morbidity score (arranged into quintile groups) and the risk of catastrophic health expenditure (adjusted).

CONCLUSIONS

If economic arguments were considered a key driver for global health policy, then depressive disorder should be considered a major health priority for women in developing countries.

Les prescriptions d'antalgiques, d'anti-inflammatoires ou le nombre d'actes radiologiques sont des facteurs prédictifs d'un traitement par antidépresseur

OBJECTIVES

Physicians frequently fail to detect mental health disorders in patients consulting them. This study tests the hypothesis that patients repeatedly prescribed analgesics or antiinflammatory drugs or X-ray examinations for unexplained somatic symptoms are at higher risk of antidepressant treatment, independent of physical comorbidity.

METHODS

This case-control study is based on health reimbursement data for self-employed artisans and shopkeepers. Cases were subjects who first began antidepressant treatment between January and March 2003. Controls, matched for age, sex, and urban or rural residence, had not been reimbursed for any psychotropic drug in the 18 months before and 6 months after this quarter. Reimbursement data for analgesic and antiinflammatory drugs, and X-rays, temporary disability payments and their reasons, chronic diseases, and hospitalizations over the 18-month period before inclusion were compared for cases and controls with simple and multiple logistic regressions.

RESULTS

The study included 988 cases (36.5% of whom were reimbursed only once for an antidepressant) and 1976 controls. The multiple logistic regressions adjusted for history of psychiatric morbidity and somatic comorbidity showed significant linear associations between starting antidepressant treatment and reimbursements for analgesic and anti-inflammatory drugs or X-rays.

DISCUSSION

Severe somatic diseases can induce psychological distress. At the same time, mental disorders may be manifested as unexplained chronic pain, without the individual recognizing the link between them.

CONCLUSION

These results confirm the initial hypothesis and suggest signs that may alert physicians to possible undetected psychological distress or mental disorders.
