Lifestyle and physical health in schizophrenia

Clozapine and cardiometabolic health in chronic schizophrenia: correlations and consequences in a clinical context

OBJECTIVE

The aim of this study was to identify the prevalence of metabolic syndrome and its putative precursors in a naturalistic study of non-acute inpatients at a psychiatric hospital.

METHOD

Anthropometric and biochemical data collected from the hospital's annual cardiometabolic survey, along with information about prescribed medications, were used to assess the prevalence and predictors of physical health problems in patients with schizophrenia.

RESULTS

Of the 167 patients included in the survey, 52.4% met criteria for metabolic syndrome. A shorter duration of hospital admission and clozapine use were significant predictors of metabolic syndrome. Age, gender, duration of admission and clozapine use were all predictors of individual cardiometabolic risk factors.

CONCLUSIONS

The findings from this naturalistic study reinforce the high prevalence of physical health problems in patients with schizophrenia and the important influence that psychiatric treatments can have on physical health. The impact of clozapine on cardiometabolic health appears to occur early in the course of treatment and emphasizes the need for proactive monitoring and interventions from the outset of management.

Schizophrenia and physical health problems

OBJECTIVE

To estimate the prevalence of physical health problems in patients with schizophrenia, and to appraise the impact on mortality rates and quality of life (QoL) in such patients.

METHOD

A selective review of clinical articles relating to physical health such as cardiovascular disease, metabolic syndrome and QoL. In addition, current guidelines and recommendations for the monitoring of physical health in schizophrenia were reviewed.

RESULTS

Cardiovascular events contribute most strongly to the excess mortality observed in schizophrenia. Other factors that contribute significantly include obesity, metabolic aberrations, smoking, alcohol, lack of exercise and poor diet - all of which might be targets for health promoting activities.

CONCLUSION

Physical health problems in patients with schizophrenia are common, and contribute to the excess mortality rate, as well as decreasing QoL. Many adverse physical factors are malleable in such patients, and physical benefit may be gained by following practical guidelines for their monitoring and improvement.

Systematic screening for metabolic syndrome in consumers with severe mental illness

The high prevalence of metabolic syndrome (MetS) in people with a mental illness has been reported recently in the literature. Gaps have emerged in the widespread use of systematic screening methods that identify this collection of critical risk factors for cardiac and metabolic disorders in people with severe mental illness. A sample (n = 103) of consumers with severe mental illness was screened for MetS using the Metabolic Syndrome Screening Tool and compared to a sample (n = 72) of consumers who were not receiving a systematic approach to screening for MetS. The results demonstrated ad hoc screening of consumers for MetS in the comparison group, potentially leaving patients at risk of cardiac and metabolic disorders being untreated. Mental health nurses are well placed to show leadership in the screening, treatment, and ongoing management of MetS in people with severe mental illness. A potential new speciality role entitled the 'cardiometabolic mental health nurse' is proposed as a means leading to improved outcomes for consumers who have both the complication of physical health problems and a severe mental illness.

Five-year mortality of Finnish schizophrenia patients in the era of deinstitutionalization

BACKGROUND

Excess mortality among people with schizophrenia due to natural and unnatural causes, especially due to suicides, is a well-known fact. It has been suggested that deinstitutionalization increases suicide mortality but there are also contradictory results. We studied the changes in mortality and causes of death among schizophrenia sufferers during and after the years of deinstitutionalization process in Finland.

METHOD

The sample, identified from the Finnish hospital discharge register (FHDR), consisted of patients aged 15-65 and hospitalized for the first time due to schizophrenia. We focused on the 5-year follow-up from inclusion years 1980-1998 (N=23,959). Changes in 5-year follow-up mortality during the study period were explored for both genders and for different causes of death separately using multivariate logistic regression analyses.

RESULTS

During the study period 1,926 deaths occurred. Suicide was the major cause of death in both genders. A significant reduction in overall 5-year mortality was observed among persons hospitalized in 1995-1998 when compared to people hospitalized 1980-1984. In males a significant reduction was seen in all mortality (P=0.025) due to suicides (P=0.007) but not in the case of natural deaths. In females no significant changes in mortality were found.

CONCLUSIONS

Our study confirms a reduction in suicide mortality of male schizophrenia sufferers after the deinstitutionalization process. However the overall mortality is still very high and the attention needs to be focused on the general well-being of schizophrenia patients.

Let's get physical

There is growing recognition and understanding of the inextricable interrelationship between physical and mental health. In mental health care, the physical health of consumers is now acknowledged as a serious problem requiring urgent action. This issue is undoubtedly related to negative symptoms and the lifestyle of people with mental illness. Much of the burden is also clearly linked with the detrimental side effects of psychotropic medications and deficits in the knowledge, skill, and confidence of mental health clinicians in relation to physical health matters. This paper highlights the problem of physical health in mental health care and presents recommendations to address this issue. The benefits of exercise on mental health in particular are explored. The authors argue that mental health nurses must play an active role in health promotion, primary prevention, and the early detection and management of physical health problems in all areas of clinical practice.

Peer Support Shows Promise in Helping Persons Living with Mental Illness Address Their Physical Health Needs

The physical health of individuals with long-term mental illnesses has long been of concern. In Western Australia, the overall mortality rate from preventable causes of people living with mental illness was reported to be 2.5 times greater than that of the general population. A trial peer support service was initiated to assist people with mental illness to attend to their physical health needs. This paper presents the planning, implementation, and results of this collaborative initiative involving nongovernment agencies, the public mental health service, consumers of mental health services, and the University of Western Australia.

Monitoring patients to improve physical health and treatment outcome

Patients with schizophrenia suffer a number of comorbidities and a range of potential side effects from their medication, which contribute to a negative impact on their quality of life, and are sometimes responsible for lack of compliance and relapse. Side effects, in particular, can be identified by physicians, but only if they examine their patients regularly. Many physicians would suggest that this is good clinical practice for treating patients with schizophrenia, whatever the intended medication. This continuous monitoring might include weight gain, cognitive effects, and blood tests. In fact, patients appreciate being carefully monitored and it contributes to a good patient/physician relationship. This interaction has benefits in terms of impact on compliance and better control of symptoms due to treatment adherence (to appropriate doses), because it enables action before the patient stops taking medication. Good clinical practice suggests that investment in patient monitoring is offset by improved clinical outcomes.

The Blue Card: a hand-held health record card for mental health consumers with comorbid physical health risk

OBJECTIVE

We aimed to determine the effectiveness of a hand-held record (the 'Blue Card') for seriously mentally ill consumers by investigating effects on consumer knowledge of physical health risk factors, consumer involvement in care and communication with healthcare professionals.

METHOD

Consumers were given and educated in the use of the Blue Card, which contained information regarding their physical health. Consumers completed a pre- and post-knowledge questionnaire and commented on the effectiveness of the Blue Card with respect to their knowledge of physical health risks.

RESULTS

Statistically significant improvements in consumer knowledge were shown at the 3-month follow-up, with high retention of the Blue Card being demonstrated. Consumers that used the card described their use of the card positively.

CONCLUSIONS

The results are very encouraging. Further studies of this low-cost intervention are warranted to establish its effectiveness and utility.

Antipsychotic induced weight gain in schizophrenia:mechanisms and management

The aim of the present paper was to describe the mechanisms and management of antipsychotic-induced weight gain in schizophrenia patients. A comprehensive literature review of all available articles on the mechanisms and management of antipsychotic-induced weight gain was done by searching databases PsychINFO and PubMed. A summary of the available guidelines for monitoring of antipsychotic-induced weight gain and metabolic syndrome is also provided. There has been a substantial increase in the number of studies investigating the mechanisms and management of antipsychotic-induced weight gain after 2002. These include advances in the understanding of pharmacogenomics of weight gain and several randomized controlled trials (RCTs) evaluating pharmacological and psychological treatments to promote weight loss. The most effective strategy for prevention of weight gain is the choice of antipsychotic medication with low weight gain potential. In individuals with established weight gain and metabolic issues, switching to an antipsychotic agent with lower weight gain potential and/or lifestyle modifications with physical activity are most effective in promoting weight loss. Pharmacological agents such as orlistat and sibutramine are effective in general obesity but have not been sufficiently evaluated in antipsychotic-induced weight gain. The case to prescribe routine pharmacological treatment to promote weight loss is weak. Long-term, pragmatic studies are required to inform clinical practice. Weight gain in schizophrenia is associated with significant physical and psychological morbidity. Achieving an optimal trade-off between effectiveness and side-effects of antipsychotic agents, although difficult, is achievable. This should be based on three main principles: (i) a shared decision-making model between the patient, clinician and carer(s) when choosing an antipsychotic; (ii) a commitment to baseline and follow-up monitoring with explicit identification of the responsible individual or team; and (iii) the adoption of clear structured protocols for clinicians to follow in case of clinically significant weight gain and metabolic issues, which should incorporate greater collaboration between various health professionals from psychiatric and medical specialist services.

Psychosocial and economic issues related to physical health in psychiatric illness

As well as the obvious medical consequences associated with physical health problems in individuals with schizophrenia, physical health problems lead to a number of psychosocial consequences--further contributing to the existing burden of schizophrenia itself. Weight gain can seriously impair quality of life through decreased functioning, social stigmatization, discrimination and potential financial consequences. However, patients with schizophrenia may be less capable of managing their weight via exercise and dietary interventions compared with the general population, and may, therefore, be more prone to non-compliance with a medication that induces weight gain. This may lead to exacerbation of the mental illness. Patients' perceptions and experience of antipsychotic treatments are also important as these can further impact on overall patient wellbeing. It is hoped that by increasing awareness of the psychosocial consequences of physical health impairment, we can move towards reducing the burden that patients face.

Delivering the choice agenda as a framework to manage adverse effects: a mental health nurse perspective on prescribing psychiatric medication

The article describes the clinical management of a patient referred, with a diagnosis of schizophrenia, who experienced adverse effects associated with an elevated prolactin level. A reflective model was adopted to inform the new learning which emerged from the clinical scenario. It highlights that Mental Health Nurse Supplementary Prescribers need to develop a prescribing value base underpinned by choice in addition to advanced technical skills to manage unhelpful effects of medication.

Health habits of patients with schizophrenia

BACKGROUND

The aim of the study was to analyze the physical activity, dietary, drinking, and smoking habits of schizophrenia patients (SP).

METHODS

Data from 194 schizophrenia outpatients collected using sections of the German National Health Interview and Examination Survey were compared with data from the German general population (GP). In addition to univariate data analyses, a multivariate regression analysis was performed.

RESULTS

Schizophrenia patients have a supper snack more frequently, consume instant meals and calorie-reduced food more frequently, and eat healthy groceries more rarely. Though they drink less alcohol, a greater proportion currently smokes, smoking on average 4 cigarettes more per day. On workdays they spend less time with strenuous activities, and in leisure time a greater proportion is involved in no sports. Regression analysis revealed that schizophrenia by itself or in interaction with demographic variables influences physical activity as well as alcohol, nicotine, and healthy grocery consumption. Health habits were particularly disadvantageously affected by schizophrenia in connection with unemployment.

CONCLUSIONS

Schizophrenia patients are an appropriate target group for public health interventions. They need information about a healthy diet and motivation to prepare their own meals, to quit smoking, and to exercise.

Physical illness and lifestyle risk factors in people with their first presentation of psychosis

BACKGROUND

There is an increased prevalence of physical illness and poor lifestyle in patients with chronic schizophrenia. It is unclear whether these are present at the onset of psychosis or develop over the course of illness. We aimed to establish whether patients experiencing their first episode of psychosis have worse physical health and lifestyle than community controls without psychosis.

METHOD

Eighty-nine patients with new onset illness were compared to age and sex matched controls for self-reported physical illness and cardiovascular and respiratory risk factors.

RESULTS

Patients reported more physical health complaints, mainly respiratory, compared with age and gender matched controls (odds ratio 2.85, 95% confidence interval 1.2-6.7). Patients were more likely to be cigarette smokers (1.82, 95% CI 1.0-3.3) and eat a fast food diet (1.04, 95% CI 1.0-1.1), but these differences were accounted for by patients' unemployment status.

CONCLUSIONS

Some risk factors for physical health problems are present at the onset of psychosis, but these may be explained by unemployment.

Current issues in providing primary medical care to people with serious mental illness

This article explores some of the current issues in providing primary care for people with serious mental illness. In contrast to many patients in the United States, up to half of patients with serious mental illness in the United Kingdom are seen only by the primary care team. However many General Practitioners feel that the care of this patient group is beyond their remit. In the United Kingdom during the last decade, there have been a variety of policy initiatives, influenced by the generic principle of "partnership working" and the increasing recognition of the importance of patient choice, that have aimed to increase the role of primary care in the delivery of health care to people with serious mental illness. On the ground, these policy imperatives have been realised through different models of shared care and schemes to encourage better communication across the primary/secondary interface. Most recently, and perhaps most effectively, the introduction of a type of performance related pay into primary care may lead to changes to the way in which General Practitioners think and act in terms of their roles and responsibilities with this patient group. Theoretically, therefore the United Kingdom may be entering a new "golden age" of primary care based mental health services for people with serious mental illness, where holistic care, preventive care and health promotion are increasingly seen not as the gold standard, but the norm.

Medical co-morbidity risk factors and barriers to care for people with schizophrenia

The management of risk is a fundamental component of the work of mental health nurses and is most commonly associated with aggressive, violent and suicidal behaviours exhibited by those suffering from mental illness. However, people with severe mental illness are increasingly at risk of experiencing a number of related and complex health problems that include obesity, diabetes and cardiovascular disease. This group also has much higher rates of morbidity and mortality than that of the general population resulting in high social, economic and individual costs. Some of the barriers to receiving prompt and appropriate physical health care include lack of recognition by health professionals and the difficulties faced by consumers of mental health services in negotiating the health care system. Establishment of comprehensive (addressing both physical and mental health issues) programmes of care can address this need and offer additional opportunities for closer and more collaborative nurse-patient relationships. This paper explores risk factors for medical co-morbidity for people living with schizophrenia and suggests strategies that can facilitate better health outcomes.

Physical health and schizophrenia

PURPOSE OF REVIEW

Patients with schizophrenia have higher than expected rates of morbidity and mortality. It is debatable whether this is related to shared risk factors, antipsychotic medication or inherent to the condition itself. This review will describe this association and the recent advances in the field.

RECENT FINDINGS

The majority of patients with schizophrenia have at least one chronic comorbid medical condition. In the absence of systematic screening this may or may not be brought to the attention of health professionals. The cause of high rates of physical illness appears to be multifactorial involving shared vulnerability and genetic factors. Yet it is vascular risk factors and the adverse effects of prescribed medication that are most amenable to intervention. Current atypical antipsychotics may offer neurological and cognitive benefits, but there is accumulating evidence of problems with weight gain, diabetes, lipid dysregulation, metabolic syndrome and sexual side effects.

SUMMARY

The physical health of patients with schizophrenia remains a concern. Yet the quality of medical and psychiatric care of patients with comorbid physical and mental health disorders has been shown to be unsatisfactory in several areas. We suggest that clinicians routinely assess and monitor physical health needs of patients with serious mental illness.
