Physical health care of patients with schizophrenia in primary care: a comparative study.

BACKGROUND: Excess morbidity and mortality associated with schizophrenia is well established. Despite this, no previous multi-centre study has investigated whether patients with schizophrenia receive equitable physical healthcare within primary care. OBJECTIVE: To determine whether patients with a diagnosis of schizophrenia receive the same levels of physical health care from primary care practitioners as patients without schizophrenia. METHODS DESIGN: Case-matched retrospective case note review. SETTING: Twenty-two general practices in the Birmingham area (UK). SUBJECTS: 195 patients with a diagnosis of schizophrenia, 390 matched controls with a diagnosis of asthma and 390 general control patients. MAIN OUTCOME MEASURES: Proportions of patients within each group having received six pre-defined routine health checks in a 3 year period. Conditional logistic regression models were used to identify differences between groups. RESULTS: Patients with schizophrenia were half as likely as asthma controls to have blood pressure and cholesterol levels recorded (odds ratio 0.51; 95% confidence interval (CI) 1.35-0.73 and 0.50; 0.31-0.82, respectively) and were also less likely to have smoking status noted (0.60; 0.41-0.85). Similarly, patients with schizophrenia were significantly less likely than general population controls to have either blood pressure or cholesterol recorded (0.68; 0.47-0.97 and 0.58; 0.35-0.95). The significant differences observed were maintained after adjusting for potential confounders with the exception of cholesterol recording between the asthma and schizophrenia groups (0.57; 0.30-1.05). CONCLUSIONS: Patients with a diagnosis of schizophrenia are less likely to receive some important general health checks than patients without schizophrenia.

Is subclinical thyroid dysfunction in the elderly associated with depression or cognitive dysfunction?

BACKGROUND: Widespread use of automated sensitive assays for thyroid hormones and thyroid-stimulating hormone (TSH) has increased identification of mild thyroid dysfunction, especially in elderly patients. The clinical significance of this dysfunction, however, remains uncertain, and associations with cognitive impairment, depression, and anxiety are unconfirmed. OBJECTIVE: To determine the association between mild thyroid dysfunction and cognition, depression, and anxiety in elderly persons. DESIGN: Cross-sectional study. Associations were explored through mixed-model analyses. SETTING: Primary care practices in central England. PATIENTS: 5865 patients 65 years of age or older with no known thyroid disease who were recruited from primary care registers. MEASUREMENTS: Serum TSH and free thyroxine (T4) were measured. Depression and anxiety were assessed by using the Hospital Anxiety and Depression Scale (HADS), and cognitive functioning was established by using the Middlesex Elderly Assessment of Mental State and the Folstein Mini-Mental State Examination. Comorbid conditions, medication use, and sociodemographic profiles were recorded. RESULTS: 295 patients met the criteria for subclinical thyroid dysfunction (127 were hyperthyroid, and 168 were hypothyroid). After confounding variables were controlled for, statistically significant associations were seen between anxiety (HADS score) and TSH level (P = 0.013) and between cognition and both TSH and free T4 levels. The magnitude of these associations lacked clinical relevance: A 50-mIU/L increase in the TSH level was associated with a 1-point reduction in the HADS anxiety score, and a 1-point increase in the Mini-Mental State Examination score was associated with an increase of 50 mIU/L in the TSH level or 25 pmol/L in the free T4 level. LIMITATIONS: Because of the low participation rate, low prevalence of subclinical thyroid dysfunction, and other unidentified recruitment biases, participants may not be representative of the elderly population. CONCLUSIONS: After the confounding effects of comorbid conditions and use of medication were controlled for, subclinical thyroid dysfunction was not associated with depression, anxiety, or cognition.

Exercise therapy as a treatment for psychopathologic conditions in obese and morbidly obese adolescents: a randomized, controlled trial.

OBJECTIVE: We conducted a proof-of-concept, randomized, controlled trial to investigate the effects of a supervised exercise therapy intervention on psychopathologic outcomes in obese adolescents. METHODS: The participant sample consisted of 81 adolescents (age: 11-16 years) who had been referred to a children's hospital for evaluation of obesity or who responded to a community advertisement. Participants were assigned randomly to exercise therapy, an equal-contact exercise placebo intervention, or usual care. Intervention participants attended 3 one-on-one sessions per week for 8 weeks and then completed a home program for another 6 weeks. Outcomes included self-perceptions (self-esteem), depression, affect, physical activity, aerobic fitness, and BMI. RESULTS: A total of 18 of 81 participants were categorized as morbidly obese (BMI SD score: > 3.5; adult equivalent BMI: > or = 40). At baseline, 30.3% of participants had a Children's Depression Inventory score of > or = 13, and 27% reported recent suicidal ideation. Repeated-measures mixed analysis of covariance (controlling for baseline scores) revealed significant changes in physical self-worth, associated measures of self-esteem, and physical activity over time, consistently favoring exercise therapy. There were no significant changes in BMI. CONCLUSIONS: Findings confirmed psychopathologic conditions as a serious health concern in obese and morbidly obese adolescents. Our study is the first randomized, controlled trial to demonstrate that a brief supervised exercise therapy intervention has the potential to improve psychopathologic outcomes significantly and to increase physical activity in obese adolescents, relative to usual care.

Gut-directed hypnotherapy for irritable bowel syndrome: piloting a primary care-based randomised controlled trial.

BACKGROUND: In western populations irritable bowel syndrome (IBS) affects between 10% and 30% of the population and has a significant effect on quality of life. It generates a substantial workload in both primary and secondary care and has significant cost implications. Gut-directed hypnotherapy has been demonstrated to alleviate symptoms and improve quality of life but has not been assessed outside of secondary and tertiary referral centres. AIM: To assess the effectiveness of gut-directed hypnotherapy as a complementary therapy in the management of IBS. DESIGN OF STUDY: Randomised controlled trial. SETTING: Primary care patients aged 18-65 years inclusive, with a diagnosis of IBS of greater than 6 weeks' duration and having failed conventional management, located in South Staffordshire and North Birmingham, UK. METHOD: Intervention patients received five sessions of hypnotherapy in addition to their usual management. Control patients received usual management alone. Data regarding symptoms and quality of life were collected at baseline and again 3, 6, and 12 months post-randomisation. RESULTS: Both groups demonstrated a significant improvement in all symptom dimensions and quality of life over 12 months. At 3 months the intervention group had significantly greater improvements in pain, diarrhoea and overall symptom scores (P<0.05). No significant differences between groups in quality of life were identified. No differences were maintained over time. Intervention patients, however, were significantly less likely to require medication, and the majority described an improvement in their condition. CONCLUSIONS: Gut-directed hypnotherapy benefits patients via symptom reduction and reduced medication usage, although the lack of significant difference between groups beyond 3 months prohibits its general introduction without additional evidence. A large trial incorporating robust economic analysis is, therefore, urgently recommended.

Prevalence of irritable bowel syndrome: a community survey.

BACKGROUND: Irritable bowel syndrome (IBS) is a common health problem affecting a substantial proportion of the population. Many individuals with symptoms of IBS do not seek medical attention or have stopped consulting because of disillusionment with current treatment options. Such patients may choose to re-consult with the advent of new therapies with a resulting impact on health services. AIM: To generate reliable estimates of the prevalence of IBS by age, sex and symptom group. DESIGN OF STUDY: Postal survey. SETTING: Patients selected from registers of eight general practices in north and west Birmingham. METHOD: Eight thousand six hundred and forty-six patients aged >or=18 years were randomly selected from practice lists. Selected patients received a questionnaire, which included diagnostic criteria for IBS. A second questionnaire, seeking more detailed information, was sent to those whose responses indicated the presence of IBS symptoms. RESULTS: Of the 8386 patients surveyed 4807 (57.3%) useable replies were received. The community-based prevalence of IBS was 10.5% (6.6% of men and 14.0% of women). Overall the symptom profiles were characterised by diarrhoea (25.4%), constipation (24.1%) and alternating symptoms (46.7%). Over half (56%) of all patients had consulted their general practitioner within the past 6 months and 16% had seen a hospital specialist. A quarter of patients consulted more than twice and 16% were referred to secondary care; almost half were on prescribed medication. However, the majority of patients were self-treated. Less than half of those currently reporting symptoms of IBS according to the Rome II criteria had received a diagnosis of IBS. Reduced quality of life and a previous diagnosis of a stomach ulcer were identified as predictors of consultation. CONCLUSION: Quality of life was significantly reduced in patients with IBS. There is a substantial burden on primary healthcare services despite over half of those with symptoms also self- medicating. The Rome II diagnostic criteria identified those most affected by their symptoms and are a valid clinical tool. Population-based health surveys will need to supplement the Rome criteria with questions aiming to identify patients formally diagnosed but whose symptoms are currently under control if prevalence is to be reliably estimated.
