Psychological problems in New Zealand primary health care: a report on the pilot phase of the Mental Health and General Practice Investigation (MaGPIe)

Aim: To carry out a pilot study in two regions in order to investigate prevalence of psychological problems in primary care in New Zealand. Method: General Practitioners (GPs) within two geographic regions were randomly selected. All adult attenders at their practice on selected days were administered a short questionnaire, the GHQ-12, which assesses the presence of psychological symptoms. The GP recorded the reasons for each consultation, and was interviewed at the end of each day about selected patients, to determine their opinion about the type of psychological problems experienced. Results: Three-quarters of selected GPs (76%) agreed to participate. 96% of patients attending their GP agreed to complete the GHQ. Scores from 385 completed GHQ screening questionnaires suggested that 23.4% of GP patients had significant psychological symptoms. When GPs were asked about the main reason for consultation, they identified only 5.7% of current consultations as being for psychological reasons. In contrast, the GPs thought that 20.6% of patients described having some symptoms which were either mildly, moderately or completely psychological in the current consultation, and recognised that 17.4% of their patients had a mild, moderate or severe case of psychological disorder over the past twelve months. Conclusion: GPs identified one in five of their patients as having symptoms which were mildly, moderately or completely psychological, although psychological factors were the main reason for consultation in only one patient in twenty. Previous reports of very low rates of psychological problems among GP attenders in New Zealand have been thought to indicate major differences in access to health care or prevalence of common mental disorders within primary care services in this country. However, the apparently low rates of conspicuous mental disorder in New Zealand general practices may be better explained as an artifact of the type of questions asked

Recognition of physical and psychological symptoms: no influence of GP demographic factors

AIM: To describe the relationship between general practitioner demographic factors and the recognition of psychological and physical symptoms in consultation. METHODS: A survey of a random sample of 70 GPs and their patients (n=3414) from the lower North Island of New Zealand. RESULTS: No relationship was found between GP personal and practice demographic characteristics and GP identification of psychological and physical symptoms. Patients were more likely not to present psychological symptoms (62%) than not present physical symptoms (5%) in consultation. Thirteen percent of GPs wanted more formal psychiatric training, 45% wanted more contact time in consultation, and 72% thought that cost was a barrier to patients attending. No significant relationship was found between these factors and GP detection of significant psychological symptoms in consultation. DISCUSSION: Personal and practice demographics of GPs may not predict their ability to detect physical and psychological symptoms. More research is needed to explore these findings which contradict previous work

The epidemiology and natural history of depressive disorders in Hong Kong's primary care

Background: Depressive disorders are commonly managed in primary care and family physicians are ideally placed to serve as central providers to these patients. Around the world, the prevalence of depressive disorders in patients presenting to primary care is between 10-20%, of which around 50% remain undiagnosed. In Hong Kong, many barriers exist preventing the optimal treatment and management of patients with depressive disorders. The pathways of care, the long term outcomes and the factors affecting prognosis of these patients requires closer examination. Methods/Design. The aim of this study is to examine the prevalence, incidence and natural history of depressive disorders in primary care and the factors influencing diagnosis, management and outcomes using a cross-sectional study followed by a longitudinal cohort study. Doctors working in primary care settings across Hong Kong have been invited to participate in this study. On one day each month over twelve months, patients in the doctor's waiting room are invited to complete a questionnaire containing items on socio-demography, co-morbidity, family history, previous doctor-diagnosed mental illness, recent mental and other health care utilization, symptoms of depression and health-related quality of life. Following the consultation, the doctors provide information regarding presenting problem, whether they think the patient has depression, and if so, whether the diagnosis is new or old, and the duration of the depressive illness if not a new diagnosis. If the doctor detects a depressive disorder, they are asked to provide information regarding patient management. Patients who consent are followed up by telephone at 2, 12, 26 and 52 weeks. Discussion. The study will provide information regarding cross-sectional prevalence, 12 month incidence, remission rate, outcomes and factors affecting outcomes of patients with depressive disorders in primary care. The epidemiology, outcomes, pathways of care, predictors for prognosis and service needs for primary care patients with depressive disorders will be described and recommendations made for policy and service planning. © 2011 Chin et al; licensee BioMed Central Ltd.published_or_final_versio

Translating research into policy: lessons learned from eclampsia treatment and malaria control in three southern African countries

<p>Abstract</p> <p>Background</p> <p>Little is known about the process of knowledge translation in low- and middle-income countries. We studied policymaking processes in Mozambique, South Africa and Zimbabwe to understand the factors affecting the use of research evidence in national policy development, with a particular focus on the findings from randomized control trials (RCTs). We examined two cases: the use of magnesium sulphate (MgSO₄) in the treatment of eclampsia in pregnancy (a clinical case); and the use of insecticide treated bed nets and indoor residual household spraying for malaria vector control (a public health case).</p> <p>Methods</p> <p>We used a qualitative case-study methodology to explore the policy making process. We carried out key informants interviews with a range of research and policy stakeholders in each country, reviewed documents and developed timelines of key events. Using an iterative approach, we undertook a thematic analysis of the data.</p> <p>Findings</p> <p>Prior experience of particular interventions, local champions, stakeholders and international networks, and the involvement of researchers in policy development were important in knowledge translation for both case studies. Key differences across the two case studies included the nature of the evidence, with clear evidence of efficacy for MgSO₄and ongoing debate regarding the efficacy of bed nets compared with spraying; local researcher involvement in international evidence production, which was stronger for MgSO₄than for malaria vector control; and a long-standing culture of evidence-based health care within obstetrics. Other differences were the importance of bureaucratic processes for clinical regulatory approval of MgSO₄, and regional networks and political interests for malaria control. In contrast to treatment policies for eclampsia, a diverse group of stakeholders with varied interests, differing in their use and interpretation of evidence, was involved in malaria policy decisions in the three countries.</p> <p>Conclusion</p> <p>Translating research knowledge into policy is a complex and context sensitive process. Researchers aiming to enhance knowledge translation need to be aware of factors influencing the demand for different types of research; interact and work closely with key policy stakeholders, networks and local champions; and acknowledge the roles of important interest groups.</p

Observational studies of depression in primary care: what do we know?

<p>Abstract</p> <p>Background</p> <p>We undertook a systematic review of observational studies of depression in primary care to determine 1) the nature and scope of the published studies 2) the methodological quality of the studies; 3) the identified recovery and risk factors for persistent depression and 3) the treatment and health service use patterns among patients.</p> <p>Methods</p> <p>Searches were conducted in MEDLINE, CINAHL and PsycINFO using combinations of topic and keywords, and Medical Subject Headings in MEDLINE, Headings in CINAHL and descriptors in PsycINFO. Searches were limited to adult populations and articles published in English during 1985–2006.</p> <p>Results</p> <p>40 articles from 17 observational cohort studies were identified, most were undertaken in the US or Europe. Studies varied widely in aims and methods making it difficult to meaningfully compare the results. Methodological limitations were common including: selection bias of patients and physicians; small sample sizes (range 35–108 patients at baseline and 20–59 patients at follow-up); and short follow-up times limiting the extent to which these studies can be used to inform our understanding of recovery and relapse among primary care patients with depression. Risk factors for the persistence of depression identified in this review were: severity and chronicity of the depressive episode, the presence of suicidal thoughts, antidepressant use, poorer self-reported quality of life, lower self-reported social support, experiencing key life events, lower education level and unemployment.</p> <p>Conclusion</p> <p>Despite the growing interest in depression being managed as a chronic illness, this review identified only 17 observational studies of depression in primary care, most of which have included small sample sizes and been relatively short-term. Future research should be large enough to investigate risk factors for chronicity and relapse, and should be conducted over a longer time frame.</p

Development and preliminary validation of an Observation List for detecting mental disorders and social Problems in the elderly in primary and home care (OLP)

Objective: Even though the prevalence of mental disorders and social problems is high among elderly patients, it is difficult to detect these in a primary (home) care setting. Goal was the development and preliminary validation of a short observation list to detect six problem areas: anxiety, depression, cognition, suspicion, loneliness, and somatisation. Methods: A draft list of indicators identified from a short review of the literature and the opinions of 22 experts was evaluated by general practitioners (GPs) and home care organisations for feasibility. It was then used by GPs and home care personnel to observe patients, who also completed validated tests forpsychological disorders (General Health Questionnaire 12 item version (GHQ-12)), depression (Geriatric Depression Scale 15-item version (GDS-15)), anxiety and suspicion (Symptom Checklist-90 (SCL-90)), loneliness (University of California, Los Angeles (UCLA)), somatisation (Illness Attitude Scale (IAS)), and cognition (Mini-Mental State Examination (MMSE)). Results: GPs and home care personnel observed 180 patients (mean age 78.4 years; 66% female) and evaluated the draft list during a regular visit. Cronbach’s α was 0.87 for the draft list and ≥0.80 for the draft problem areas (loneliness and suspicion excepted). Principal component analysis identi fied six components (cognition, depression + loneliness, somatisation, anxiety + suspicion, depression (other signs), and an ambiguous component). Convergent validity was shown for the indicators list as a whole (using the GHQ-12), and the subscales of depression, anxiety, loneliness, cognition, and somatisation. Using pre-set agreed criteria, the list was reduced to 14 final indicators divided over five problem areas. Conclusion: The Observation List for mental disorders and social Problems (OLP) proved to be prelim- inarily valid, reliable, and feasible for use in primary and home care settings
