Suicidal ideation and physical illness: Does the link lie with depression?

Objective
Medical illness is a risk factor for suicidality; however, disorder-specific risks are not well-known and these relationships are often explained by major depressive disorder (MDD). We aimed to investigate the relationship between suicidal ideation, MDD and medical illnesses in an age-stratified, population-based sample of men participating in the Geelong Osteoporosis Study.

Methods
Suicidal ideation and medical conditions were self-reported. Medical conditions were confirmed by medical records, medication use or clinical data where possible. MDD was determined using the Structured Clinical Interview for DSM-IV-TR Research Version, Non-patient edition.

Results
Of the 907 men, 8.5% reported suicidal ideation. Thyroid disorders (OR 3.85, 95%CI 1.2–12.1), syncope and seizures (OR 1.96, 95%CI 1.1–3.5), liver disorders (OR 3.53, 95%CI 1.1–11.8; younger men only) and alcoholism (OR 2.15, 95%CI 1.1–4.4) were associated with increased odds of suicidal ideation, independent of age and MDD. Major vascular events doubled the odds of suicidal ideation but this was explained by MDD. No association was evident with high medical burden, musculoskeletal disease, metabolic factors, gastrointestinal disorders, headaches, cardiovascular disease, COPD, cancer and psoriasis.

Conclusion
Health care professionals should focus on identification, assessment and management of suicidal ideation in the medically ill in patients both with and without MDD.

Self-administration of medication in hospital: patients' perspectives

Background. Little information is available about patients' perspectives on self- or nurse-related administration of medication.

Aim. The aim of the study was to determine patients' perspectives about self-medication in the acute care setting.

Methods. A qualitative approach, using in-depth semi-structured interviews, was taken. Ten patients with a chronic medical illness who had experienced multiple hospital admissions for treatment were interviewed about their experiences of medication administration in the acute care setting. Participants were recruited from two cardiovascular wards in a private, not-for-profit hospital in Melbourne, Australia. Data collection occurred between August and September 2002.

Findings. Four major themes were identified from the interviews: benefits of self-administration, barriers to self-administration, assessing appropriateness of self-administration and timing of medication administration. Seven participants had previously experienced self-administration of medications and six were in favour of this practice in the clinical setting. Nine managed their own medications at home, and one self-administered with some assistance from his family. Participants were very concerned about how nurses' heavily regulated routines affected delivery of medications in hospital and disrupted individualized plans of care maintained in the home setting.

Conclusions. In planning and implementing self-administration programmes, it is important to consider patients' views. Medication regimes should be simple and flexible enough to adapt to patients' lifestyles and usual routines. Nurses should also take advantage of opportunities to support and facilitate patient autonomy, to enable more effective management of health care needs when patients return home.

A qualitative examination of the experience of 'depression' in hospitalized medically ill patients

Background: Research into depression in the medically ill has progressed without sufficient attention being given to the validity, in this group, of the taxonomic categories. We aimed to describe, using qualitative interviews, the experience of 'being depressed', separating experiences that are unique to depression from experiences that are common to being ill and in hospital.
Method: Forty-nine patients hospitalized for medical illness underwent a 30-min interview in which they were asked to 'Describe how you have been unwell and, in particular, how that has made you feel.' From the transcripts, a 'folk' taxonomy was constructed using a phenomenological framework involving four steps: frame elicitation to identify the important themes, componential analysis to systematically cluster the attributes into domains, a comparison of the experiences of patients screening depressed and  not-depressed, and a theoretical analysis comparing the resulting taxonomy with currently used theoretical constructs.
Results: Experiences common to all patients were being in hospital, being ill or in pain, adjusting to not being able to do things, and having time to think. In addition, all participants described being depressed, down or sad. Patients who were identified by screening as being depressed described unique experiences of depression, which included 'having to think about things' (a forceful intrusive thinking), 'not being able to sleep', 'having to rely on others', 'being a burden' to others (with associated shame and guilt), feelings of 'not getting better' and 'feeling like giving up'. Theoretical analysis suggested that this experience of depression fitted well with the concept of demoralization described by Jerome Frank.
Conclusions: Demoralization, which involves feelings of being unable to cope, helplessness, hopelessness and diminished personal esteem, characterizes much of the depression seen in hospitalized medically ill patients

Depression's multiple comorbidities explained by (neuro)inflammatory and oxidative & nitrosative stress pathways

There is now evidence that depression, as characterized by melancholic symptoms, anxiety, and fatigue and somatic (F&S) symptoms, is the clinical expression of peripheral cell-mediated activation, inflammation and induction of oxidative and nitrosative stress (IO&NS) pathways and of central microglial activation, decreased neurogenesis and increased apoptosis. This review gives an explanation for the multiple “co-morbidities” between depression and a large variety of a) brain disorders related to neurodegeneration, e.g. Alzheimer’s, Parkinson’s and Huntington’s disease, multiple sclerosis and stroke; b) medical disorders, such as cardiovascular disorder, chronic fatigue syndrome, chronic obstructive pulmonary disease, rheumatoid arthritis, psoriasis, systemic lupus erythematosus, inflammatory bowel disease, irritable bowel syndrome, leaky gut, diabetes type 1 and 2, obesity and the metabolic syndrome, and HIV infection; and c) conditions, such as hemodialysis, interferon-α-based immunotherapy, the postnatal period and psychosocial stressors. The common denominator of all those disorders/conditions is the presence of microglial activation and/or activation of peripheral IO&NS pathways. There is evidence that shared peripheral and / or central IO&NS pathways underpin the pathophysiology of depression and the previously mentioned disorders and that activation of these IO&NS pathways contributes to shared risk. The IO&NS pathways function as a smoke sensor that detect threats in the peripheral and central parts of the body and signal these threats as melancholic, anxiety, and fatigue and somatic (F&S) symptoms. The presence of concomitant depression is strongly associated with a lower quality of life and increased morbidity and mortality in medical disorders. This may be explained since depression contributes to increased (neuro)inflammatory burden and may therefore drive the inflammatory and degenerative progression. It is concluded that the activation of peripheral and / or central IO&NS pathways may explain the co-occurrence of depression with the above disorders. This shows that depression belongs to the spectrum of inflammatory and degenerative disorders.

Indications for computed tomographic brain scanning in psychiatric inpatients.

This study examined the rate of use of computed tomographic (CT) scanning as well as clinical parameters pertaining to that used in psychiatric patients. These patients were compared with a randomly selected control group of psychiatric patients who were not scanned. In addition, scan abnormalities were examined and correlated with clinical and electro-encephalographic (EEG) data. CT scanning was used on 13.5% of admissions. On axis 1 of the DSM III-R, the CT scan group had a significantly higher incidence of delirium and dementia (P < 0.05) and a much higher rate of medical illness (P < 0.01) on axis 3. The rate of CT abnormality was fairly high at 45.2%. An abnormal CT scan was associated with the diagnosis of dementia, the presence of organic mental status abnormality and of abnormality on neurological examination. Focally abnormal CT scans were associated with focally abnormal EEGs in a significant number of patients (P < 0.05).

Illness burden and medical comorbidity in the systematic treatment enhancement program for bipolar disorder

Objective:  Coexisting chronic medical conditions are common in bipolar disorder. Here, we report the prevalence and correlates of medical comorbidity in patients enrolled in the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD). We were particularly interested in associations between variables reflecting illness chronicity and burden with comorbid medical conditions.

Method:  We used intake data from the open-label component of the STEP-BD. History of medical comorbidity was obtained from the affective disorders evaluation, and its presence was the outcome of interest. The sample size in analyses varied from 3399 to 3534. We used multiple Poisson regression to obtain prevalence ratios.

Results:  The prevalence of any medical comorbidity in the sample was 58.8%. In addition to demographic variable, several clinical characteristics were associated with the frequency of medical comorbidity. Having more than 10 previous mood episodes, childhood onset, smoking, lifetime comorbidity with anxiety, and substance use disorders were independently associated with having a medical comorbidity in the final multivariate model.

Conclusion:  The results presented here reveal strong associations between variables related to illness chronicity and medical burden in bipolar disorder. This lends further support to recent multidimensional models incorporating medical morbidity as a core feature of bipolar disorder.

Can the direct medical cost of chronic disease be transferred across different countries? Using cost-of-illness studies on type 2 diabetes, epilepsy and schizophrenia as examples

OBJECTIVES: To systematically review cost of illness studies for schizophrenia (SC), epilepsy (EP) and type 2 diabetes mellitus (T2DM) and explore the transferability of direct medical cost across countries.

METHODS: A comprehensive literature search was performed to yield studies that estimated direct medical costs. A generalized linear model (GLM) with gamma distribution and log link was utilized to explore the variation in costs that accounted by the included factors. Both parametric (Random-effects model) and non-parametric (Boot-strapping) meta-analyses were performed to pool the converted raw cost data (expressed as percentage of GDP/capita of the country where the study was conducted).

RESULTS: In total, 93 articles were included (40 studies were for T2DM, 34 studies for EP and 19 studies for SC). Significant variances were detected inter- and intra-disease classes for the direct medical costs. Multivariate analysis identified that GDP/capita (p<0.05) was a significant factor contributing to the large variance in the cost results. Bootstrapping meta-analysis generated more conservative estimations with slightly wider 95% confidence intervals (CI) than the parametric meta-analysis, yielding a mean (95%CI) of 16.43% (11.32, 21.54) for T2DM, 36.17% (22.34, 50.00) for SC and 10.49% (7.86, 13.41) for EP.

CONCLUSIONS: Converting the raw cost data into percentage of GDP/capita of individual country was demonstrated to be a feasible approach to transfer the direct medical cost across countries. The approach from our study to obtain an estimated direct cost value along with the size of specific disease population from each jurisdiction could be used for a quick check on the economic burden of particular disease for countries without such data.

Overcoming the stigma of chronic illness: strategies for normalisation of a 'spoiled identity'

This paper addresses the concept of chronic illness as a socially constructed experience of stigma. The stigma of having a chronic illness affects the person's self-concept, capacity to adapt to the illness and the quality of his/her social networks. Social stigma is a delegitimising social process derived from both popular and medical views of chronic illness. Based on research into the coping strategies of a range of people with long-term, serious chronic illnesses, the paper argues that government health policies and services in Australia can best help people with chronic illness by supporting their self-help groups and community-based activities.

Focus group study of endometriosis: struggle, loss and the medical merry-go-round

Women with endometriosis experience a range of problems for which they may or may not be adequately supported. This paper reports on one aspect of a study conducted at the Epworth Hospital, Melbourne, to identify the information needs of women facing laparoscopy for endometriosis. A number of focus groups were conducted that provided women with a forum for communicating their experiences of endometriosis and laparoscopy. The findings include the experiences of 61 women who described the lack of support, the struggles and the losses involved in living with endometriosis. By far the worst experience that these women described was the encounter with health professionals and the ways in which their symptoms were trivialised and dismissed. There is a great deal for nurses to learn about the experience of living with endometriosis if they are to support women with this chronic illness in their search for well-being.

Disentangling the stigma of HIV/AIDS from the stigmas of drugs use, commercial sex and commercial blood donation - a factorial survey of medical students in China

Background
HIV/AIDS related stigma interferes with the provision of appropriate care and support for people living with HIV/AIDS. Currently, programs to address the stigma approach it as if it occurs in isolation, separate from the co-stigmas related to the various modes of disease transmission including injection drug use (IDU) and commercial sex (CS). In order to develop better programs to address HIV/AIDS related stigma, the inter-relationship (or 'layering') between HIV/AIDS stigma and the co-stigmas needs to be better understood. This paper describes an experimental study for disentangling the layering of HIV/AIDS related stigmas.

Methods
The study used a factorial survey design. 352 medical students from Guangzhou were presented with four random vignettes each describing a hypothetical male. The vignettes were identical except for the presence of a disease diagnosis (AIDS, leukaemia, or no disease) and a co-characteristic (IDU, CS, commercial blood donation (CBD), blood transfusion or no co-characteristic). After reading each vignette, participants completed a measure of social distance that assessed the level of stigmatising attitudes.

Results
Bivariate and multivariable analyses revealed statistically significant levels of stigma associated with AIDS, IDU, CS and CBD. The layering of stigma was explored using a recently developed technique. Strong interactions between the stigmas of AIDS and the co-characteristics were also found. AIDS was significantly less stigmatising than IDU or CS. Critically, the stigma of AIDS in combination with either the stigmas of IDU or CS was significantly less than the stigma of IDU alone or CS alone.

Conclusion
The findings pose several surprising challenges to conventional beliefs about HIV/AIDS related stigma and stigma interventions that have focused exclusively on the disease stigma. Contrary to the belief that having a co-stigma would add to the intensity of stigma attached to people with HIV/AIDS, the findings indicate the presence of an illness might have a moderating effect on the stigma of certain co-characteristics like IDU. The strong interdependence between the stigmas of HIV/AIDS and the co-stigmas of IDU and CS suggest that reducing the co-stigmas should be an integral part of HIV/AIDS stigma intervention within this context.

The role of peer support in facilitating psychosocial adjustment to chronic illness in adolescence

This article describes a Chronic Illness Peer Support (ChIPS) programme designed to assist young people in their adjustment to life with a chronic medical condition. The ChIPS programme takes a non-categorical approach to participation, recognizing that young people with different medical conditions experience many similar concerns. Support groups are facilitated by a health professional and peer co-leader. Groups meet weekly for 8 weeks and typically include between six and eight young people. Young people can choose to remain involved in broader social, educational and recreational activities following completion of the 8-week programme. We discuss nine psychosocial mechanisms by which peer support groups such as ChIPS might act to improve resilience and well-being among participants. We also discuss some theoretical risks in running support groups for chronically ill young people, which emphasize the importance of training and support of group leaders, including the peer co-leaders. The article concludes with a personal testimony by a ChIPS participant that was prepared for the 2003 Australian and New Zealand Adolescent Health Conference.

Health risk behaviours and health care needs among people with psychiatric illness

This paper presents findings from two studies. Study 1 explored differences between people with psychiatric illness (PPI) (N=144) and the general population (N=151) in levels of low-fat diet, exercise and smoking. Study 2 investigated barriers and health care needs of PPI (N=60). The prevalence of overweight, cigarette smoking and sedentary lifestyle were significantly greater among PPI than the general population. Major predictors were limited social support, knowledge of correct dietary principles, lower self-efficacy, psychiatric symptomatology and various psychotropic drugs. The findings demonstrated that PPI over-used medical services but under-used preventive services due to inaccessibility, lower satisfaction and knowledge of services.

Chronic illness and its impact : considerations for psychologists

A significant proportion of the population is affected by chronic illnesses, which have a marked impact on psychological adjustment at both the individual and family level. The nature of these illnesses and their impacts is complex, and has implications for psychological practice. This paper reviews these issues, and argues that more emphasis should be given to medical conditions in training programmes for psychologists.

Illness representations and cancer screening in older women

This research investigated why some older women do not obtain screening mammograms and Pap smear tests. In-depth interviews found many beliefs which are contrary to screening and influenced the women's screening behaviour.

Adolescent chronic illness : a qualitative study of psychosocial adjustment

Introduction: The purpose of this study was to investigate the psychosocial issues facing young people living with a chronic medical condition.

Materials and Methods: Subjects were young people with a range of medical conditions who were on a waiting list to participate in the Chronic Illness Peer Support programme at the Centre for Adolescent Health, Royal Children's Hospital, Melbourne, Australia. Young people agreed to in-depth interviews which were taped and transcribed. Thematic analysis was undertaken by two researchers working independently.

Results: Thirty-five young people were interviewed. Thematic analysis revealed five broad themes: control (in control, under control, out of control); emotional reactions (happiness, frustration, anger, sadness, anxiety); acceptance (of illness, of others, of self); coping strategies, and; a search for meaning. The importance of social connections was emphasised. While illustrating the difficulties of managing a chronic medical condition during adolescence, a generally positive message emerges about these young people.

Conclusions: Many young people with chronic illness appear relatively resilient in the face of the adjustment challenges presented by their illness. Interventions that allow a young person to explore meaning, build self-esteem, and acceptance through positive social connections are likely to improve adjustment outcomes in this group.
