An international study of the effect of physical ill health on psychiatric recovery in primary care

Getting under the skin: Does biology help predict chronicity of depression?

BACKGROUND

Depressed patients are at risk of an unfavourable course including chronic episodes. Various psychiatric characteristics have shown to be predictive of depression's course trajectory, but whether indicators of somatic health further contribute to course prediction remains unclear. This study aimed to identify somatic health indicators (i.e. biomarkers, health status and lifestyle) that predict 2-year chronicity above and beyond an extensive list of sociodemographic and psychiatric characteristics.

METHODS

Data are from patients with current depression at baseline (n = 903) and available 2-year follow-up participating in a longitudinal cohort study. Baseline demographic, psychiatric and somatic health indicators were associated with 2-year course trajectories, classified as non-chronic versus chronic RESULTS: At 2-year follow up, 40% of the patients showed a chronic course. Of the twenty tested somatic health indicators, short sleep and high interleukin-6 improved the regression model predicting chronicity with a significant, but modest, effect (ROC = 0.78; p = 0.03).

LIMITATIONS

Due to the observational design we did not have the ability to reliably consider the impact of psychiatric treatment. More elaborate information on somatic health such as dietary patterns would strengthen the study.

CONCLUSIONS

This study showed that short sleep duration and high interleukin-6 contributed significantly to the regression model as independent predictors, suggestive of clinical implications for patients with sleep disturbances and elevated inflammation levels. Other somatic health indicators did not add to the model. Overall, somatic health indicators showed modest additive value for predicting chronic course above and beyond sociodemographic and psychiatric indicators.

The effect of chronic physical illnesses on psychiatric hospital admission in patients with recurrent major depression

People with major depressive disorder (MDD) have an increased burden of chronic physical illnesses (CPI). However, information about the effect of CPIs on recurrent MDD treatment outcome is limited. The objective of this study was to explore whether the number of CPIs in patients with recurrent MDD was associated with higher rate of psychiatric admissions. Data were collected for a consecutive sample of 190 patients diagnosed with recurrent MDD. The key outcome was the number of psychiatric admissions following psychiatric diagnosis. The independent variable was the number of CPIs. The effects of different clinical, sociodemographic, and lifestyle confounding factors were controlled using robust regression. The patients with CPI had significantly more psychiatric admissions than the patients without CPI, and the number of CPIs was significantly associated with the number of psychiatric admissions. The results of our study largely confirmed that more than two CPIs in patients diagnosed with recurrent MDD are associated with higher rates of psychiatric admission, independent of psychiatric comorbidities and other clinical and sociodemographic factors. These findings indicate that to improve treatment outcome and to reduce recurrence, it is crucial to enhance early recognition and treatment of physical comorbidity.

Patient care activities by community pharmacists in a capitation funding model mental health and addictions program

BACKGROUND

Community pharmacists are autonomous, regulated health care professionals located in urban and rural communities in Canada. The accessibility, knowledge, and skills of community pharmacists can be leveraged to increase mental illness and addictions care in communities.

METHODS

The Bloom Program was designed, developed, and implemented based on the Behaviour Change Wheel and a program of research in community pharmacy mental healthcare capacity building. We evaluated the Bloom Program as a demonstration project using mixed methods. A retrospective chart audit was conducted to examine outcomes and these are reported in this paper.

RESULTS

We collected 201 patient charts from 23 pharmacies in Nova Scotia with 182 patients having at least one or more follow-up visits. Anxiety (n = 126, 69%), depression (n = 112, 62%), and sleep disorders (n = 64, 35%) were the most frequent mental health problems. Comorbid physical health problems were documented in 57% (n = 104). The average number of prescribed medications was 5.5 (range 0 to 24). Sixty seven percent (n = 122) were taking multiple psychotropics and 71% (n = 130) reported taking more than one medication for physical health problems. Treatment optimization was the leading reason for enrollment with more than 80% seeking improvements in symptom management and daily functioning. There were a total of 1233 patient-care meetings documented, of which the duration was recorded in 1098. The median time for enrolling, assessing, and providing follow-up care by pharmacists was 142 min (mean 176, SD 128) per patient. The median follow-up encounter duration was 15 min. A total of 146 patient care encounters were 60 min or longer, representing 13.3% of all timed encounters.

CONCLUSIONS

Pharmacists work with patients with lived experience of mental illness and addictions to improve medication related outcomes including those related to treatment optimization, reducing polytherapy, and facilitating withdrawal from medications. Pharmacists can offer their services frequently and routinely without the need for an appointment while affording patient confidentiality and privacy. Important roles for pharmacists around the deprescribing of various medications (e.g., benzodiazepines) have previously been supported and should be optimized and more broadly implemented. Further research on the best mechanisms to incentivize pharmacists in mental illness and addiction's care should be explored.

From personal crisis care to convenience shopping: an interpretive description of the experiences of people with mental illness and addictions in community pharmacies

BACKGROUND

The role of community pharmacists is changing globally with pharmacists engaging in more clinically-oriented roles, including in mental health care. Pharmacists' interventions have been shown to improve mental health related outcomes but various barriers can limit pharmacists in their care of patients. We aimed to explore the experiences of people with lived experience of mental illness and addictions in community pharmacies to generate findings to inform practice improvements.

METHODS

We used interpretive description methodology with analytic procedures of thematic analysis to explore the experiences of people with lived experience of mental illness and addictions with community pharmacy services. Participants were recruited through multiple mechanisms (e.g., paper and online advertisements), offered honorarium for their time, and given the option of a focus group or interview for participation in our study. Data were gathered during July to September of 2012. Interviews and focus groups were audio-recorded, transcribed verbatim, and analyzed by two researchers.

RESULTS

We collected approximately nine hours of audio data from 18 individuals in two focus groups (n = 12) and six individual interviews. Fourteen participants were female and the average age was 41 years (range 24 to 57 years). Expectations, decision-making, and supports were identified as central themes underlying the community pharmacy experiences of people with lived experience of mental illness and addictions. Eight subthemes were identified including: relationships with pharmacy staff; patient's role in the pharmacist-patient relationship; crisis and triage; privacy and confidentiality; time; stigma and judgment; medication-related and other services; and transparency.

CONCLUSIONS

People with lived experience of mental illness and addictions demonstrate a high regard and respect for pharmacist's knowledge and abilities but hold conservative expectations of pharmacy health services shaped by experience, observations, and assumptions. To some extent, expectation management occurs with the recognition of the demands on pharmacists and constraints inherent to community pharmacy practice. Relationships with pharmacy staff are critical to people with lived experience and influence their decision-making. Research in the area of pharmacists' roles in crises and triage, especially in the area of suicide assessment and mitigation, is needed urgently.

Acute hospital service utilization by inpatients in psychiatric hospitals

OBJECTIVE

Standardized mortality ratios are twice the population average in the year following a mental health admission, yet there is a relative paucity of research on uptake of general medical care in psychiatric inpatients.

METHODS

A retrospective database analysis was performed to ascertain the frequency of acute medical care usage by psychiatric inpatients. Data were gathered through a static linkage between anonymized clinical records in a large UK mental health provider and the national hospital activity database (Hospital Episode Statistics) over 1year from 2010 to 2011.

RESULTS

Over the year, 10.4% of the 8023 psychiatric admission episodes included at least one night in a general hospital during that psychiatric inpatient stay, while 12.0% of psychiatry admission episodes entailed an emergency department (ED) visit. Over the course of the full year, of the 4674 people admitted to the mental health provider at least once, 16.0% were admitted to a general hospital while registered as a mental health inpatient and 18.0% were seen in the ED. Patients were simultaneously registered as occupying beds in both general and psychiatric hospitals for a total of 5163 bed days at a cost of £2.4 million over the year.

CONCLUSION

This large population-based linkage study indicates a high rate of general hospital utilization by psychiatric inpatients in an independent mental health provider. The need for combined, flexible and practical approaches to the medical care of psychiatric inpatients is highlighted to reduce unplanned care and provide treatment in the site best suited to the patient's needs.

Serious mental illness and the role of primary care

Policies and guidelines from across the international community are attempting to galvanise action to address the unacceptably high morbidity and mortality rates amongst people with a serious mental illness (SMI). Primary care has a pivotal role to play in translating policy into evidence based practice in conjunction with other providers of health care services. This paper explores the current and potential of role of primary care providers in delivering health care to people with SMI. A review of research in the following key areas of primary health care provision is provided: access, screening and preventative care, routine monitoring and follow-up, diagnosis and delivery of treatments in accordance with guidelines and delivery of interventions. There is undoubtedly a need for further research to establish the effectiveness of primary care interventions and the organisation of services. Equally, understanding how primary care services can deliver high quality care and promoting effective working at the interface with other services must be priorities.

Composite International Diagnostic Interview screening scales for DSM-IV anxiety and mood disorders

BACKGROUND

Lack of coordination between screening studies for common mental disorders in primary care and community epidemiological samples impedes progress in clinical epidemiology. Short screening scales based on the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI), the diagnostic interview used in community epidemiological surveys throughout the world, were developed to address this problem.

METHOD

Expert reviews and cognitive interviews generated CIDI screening scale (CIDI-SC) item pools for 30-day DSM-IV-TR major depressive episode (MDE), generalized anxiety disorder (GAD), panic disorder (PD) and bipolar disorder (BPD). These items were administered to 3058 unselected patients in 29 US primary care offices. Blinded SCID clinical reinterviews were administered to 206 of these patients, oversampling screened positives.

RESULTS

Stepwise regression selected optimal screening items to predict clinical diagnoses. Excellent concordance [area under the receiver operating characteristic curve (AUC)] was found between continuous CIDI-SC and DSM-IV/SCID diagnoses of 30-day MDE (0.93), GAD (0.88), PD (0.90) and BPD (0.97), with only 9-38 questions needed to administer all scales. CIDI-SC versus SCID prevalence differences are insignificant at the optimal CIDI-SC diagnostic thresholds (χ2 1 = 0.0-2.9, p = 0.09-0.94). Individual-level diagnostic concordance at these thresholds is substantial (AUC 0.81-0.86, sensitivity 68.0-80.2%, specificity 90.1-98.8%). Likelihood ratio positive (LR+) exceeds 10 and LR- is 0.1 or less at informative thresholds for all diagnoses.

CONCLUSIONS

CIDI-SC operating characteristics are equivalent (MDE, GAD) or superior (PD, BPD) to those of the best alternative screening scales. CIDI-SC results can be compared directly to general population CIDI survey results or used to target and streamline second-stage CIDIs.

Differences in the prescribing of medication for physical disorders in individuals with v. without mental illness: meta-analysis

BACKGROUND

There is some concern that patients with mental illness may be in receipt of inferior medical care, including prescribed medication for medical conditions.

AIMS

We aimed to quantify possible differences in the prescription of medication for medical conditions in those with v. without mental illness.

METHOD

Systematic review and random effects meta-analysis with a minimum of three independent studies to warrant pooling by drug class.

RESULTS

We found 61 comparative analyses (from 23 publications) relating to the prescription of 12 classes of medication for cardiovascular health, diabetes, cancer, arthritis, osteoporosis and HIV in a total sample of 1 931 509 people. In those with severe mental illness the adjusted odds ratio (OR) for an equitable prescription was 0.74 (95% CI 0.63-0.86), with lower than expected prescriptions for angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (ACE/ARBs), beta-blockers and statins. People with affective disorder had an odds ratio of 0.75 (95% CI 0.55-1.02) but this was not significant. Individuals with a history of other (miscellaneous) mental illness had an odds ratio of 0.95 (95% CI 0.92-0.98) of comparable medication with lower receipt of ACE/ARBs but not highly active antiretroviral therapy (HAART) medication. Results were significant in both adjusted and unadjusted analyses.

CONCLUSIONS

Individuals with severe mental illness (including schizophrenia) appear to be prescribed significantly lower quantities of several common medications for medical disorders, largely for cardiovascular indications, although further work is required to clarify to what extent this is because of prescriber intent.

Mental health needs and service utilization by Hispanic immigrants residing in mid-southern United States

PURPOSE

This study assessed mental health needs and service utilization patterns in a convenience sample of Hispanic immigrants.

DESIGN

A total of 84 adult Hispanic participants completed a structured diagnostic interview and a semistructured service utilization interview with trained bilingual research assistants.

RESULTS

In the sample, 36% met diagnostic criteria for at least one mental disorder. Although 42% of the sample saw a physician in the prior year, mental health services were being rendered primarily by religious leaders. The most common barriers to service utilization were cost (59%), lack of health insurance (35%), and language (31%). Although more women than men met criteria for a disorder, service utilization rates were comparable. Participants with a mental disorder were significantly more likely to have sought medical, but not psychiatric, services in the prior year and faced significantly more cost barriers than participants without a mental disorder.

CONCLUSIONS

Findings suggest that Hispanic immigrants, particularly those with a mental illness, need to access services but face numerous systemic barriers. The authors recommend specific ways to make services more affordable and linguistically accessible.

Do deficits in cardiac care influence high mortality rates in schizophrenia? A systematic review and pooled analysis

We have previously documented inequalities in the quality of medical care provided to those with mental ill health but the implications for mortality are unclear. We aimed to test whether disparities in medical treatment of cardiovascular conditions, specifically receipt of medical procedures and receipt of prescribed medication, are linked with elevated rates of mortality in people with schizophrenia and severe mental illness. We undertook a systematic review of studies that examined medical procedures and a pooled analysis of prescribed medication in those with and without comorbid mental illness, focusing on those which recruited individuals with schizophrenia and measured mortality as an outcome. From 17 studies of treatment adequacy in cardiovascular conditions, eight examined cardiac procedures and nine examined adequacy of prescribed cardiac medication. Six of eight studies examining the adequacy of cardiac procedures found lower than average provision of medical care and two studies found no difference. Meta-analytic pooling of nine medication studies showed lower than average rates of prescribing evident for the following individual classes of medication; angiotensin converting enzyme inhibitors (n = 6, aOR = 0.779, 95% CI = 0.638-0.950, p = 0.0137), beta-blockers (n = 9, aOR = 0.844, 95% CI = 0.690-1.03, p = 0.1036) and statins (n = 5, aOR = 0.604, 95% CI = 0.408-0.89, p = 0.0117). No inequality was evident for aspirin (n = 7, aOR = 0.986, 95% CI = 0.7955-1.02, p = 0.382). Interestingly higher than expected prescribing was found for older non-statin cholesterol-lowering agents (n = 4, aOR = 1.55, 95% CI = 1.04-2.32, p = 0.0312). A search for outcomes in this sample revealed ten studies linking poor quality of care and possible effects on mortality in specialist settings. In half of the studies there was significantly higher mortality in those with mental ill health compared with controls but there was inadequate data to confirm a causative link. Nevertheless, indirect evidence supports the observation that deficits in quality of care are contributing to higher than expected mortality in those with severe mental illness (SMI) and schizophrenia. The quality of medical treatment provided to those with cardiac conditions and comorbid schizophrenia is often suboptimal and may be linked with avoidable excess mortality. Every effort should be made to deliver high-quality medical care to people with severe mental illness.

Capturing complexity: The case for a new classification system for mental disorders in primary care

Primary care differs considerably from specialist mental health settings: problems are presented in undifferentiated forms, with consequent difficulties in distinguishing between distress and disorder, and a complex relationship between psychological, mental and social problems and their temporal variations.

Existing psychiatric diagnostic systems, including ICD-10-PHC and DSM-IV-PC, are often difficult to apply in primary care. They do not adequately address co-morbidity, the substantial prevalence of sub-threshold disorders or problems with cross-cultural applications. Their focus on diagnosis may be too restrictive, with a need to consider severity and impairment separately.

ICPC-2, a classification system created specifically for use in primary care, provides advantages in that it allows for simple linkage between reason for encounter, diagnosis and intervention.

It is both necessary and feasible to develop a classification system for mental health in primary care that can meet four basic criteria: (1) characterized by simplicity; (2) addressing not only diagnosis but also severity, chronicity and disability; (3) feasible for routine data gathering in primary care as well as for training; and (4) enabling efficient communication between primary and specialty mental health care.

A comparison of benzodiazepine and related drug use in Nova Scotia and Australia

OBJECTIVE

Benzodiazepines can be a problem if used for long periods, or in at-risk populations, such as the elderly. We compared the use of benzodiazepine and related prescription medicines in Nova Scotia and Australia.

METHODS

The Nova Scotia Pharmacare Program and the Pharmaceutical Benefits Scheme in Australia were used to obtain dispensing data in comparable populations for all publicly subsidized benzodiazepines and related compounds. Usage was compared from 2000 to 2003, using the World Health Organization anatomical therapeutic chemical and defined daily dosage (DDD) system. We also determined differences in the types of benzodiazepines prescribed.

RESULTS

The use of benzodiazepines increased at a steady but comparable rate in both areas. However, the use of benzodiazepines in Nova Scotia was more than double that of Australia in 2000 (123 and 48 DDD/1000 beneficiaries per day, respectively) through 2003 (138 and 57 DDD/1000 beneficiaries per day, respectively). Eight different benzodiazepines made up 90% of the drug use in Nova Scotia by contrast to only 4 different benzodiazepines in Australia.

CONCLUSIONS

Large differences exist between the type and rate of benzodiazepine prescribing in Nova Scotia and Australia, with Nova Scotia reporting more than twice as much use. Benzodiazepine use in both jurisdictions is increasing. The Canadian findings are especially concerning as benzodiazepine use in the Atlantic provinces has been reported to be less than other provinces. The variations between the 2 jurisdictions may be due to factors such as fewer benzodiazepines available in Australia, differences in prescriber, patient attitudes and behaviours, or different initiatives to influence benzodiazepine use.

Taking consultation-liaison psychiatry into primary care

Up to 50% of patients seen in primary care have mental health problems, the severity and duration of their problems often being similar to those of individuals seen in the specialized sector. This article describes the reasons, advantages, and challenges of collaborative or shared care between primary and mental health teams, which are similar to those of consultation-liaison psychiatry. In both settings, clinicians deal with the complex interrelationships between medical and psychiatric disorders. Although initial models emphasized collaboration between family physicians, psychiatrists, and nurses, collaborative care has expanded to involve patients, psychologists, social workers, occupational therapists, pharmacists, and other providers. Several factors are associated with favorable patient outcomes. These include delivery of interventions in primary care settings by providers who have met face-to-face and/or have pre-existing clinical relationships. In the case of depression, good outcomes are particularly associated with approaches that combined collaborative care with treatment guidelines and systematic follow-up, especially for those with more severe illness. Family physicians with access to collaborative care also report greater knowledge, skills, and comfort in managing psychiatric disorders, even after controlling for possible confounders such as demographics and interest in psychiatry. Perceived medico-legal barriers to collaborative care can be addressed by adequate personal professional liability protection on the part of each practitioner, and ensuring that other health care professionals with whom they work collaboratively are similarly covered.

Contribution of depression and anxiety to impaired health-related quality of life following first myocardial infarction

BACKGROUND

The extent to which depression impairs health-related quality of life (HRQoL) in the physically ill has not been clearly established.

AIMS

To quantify the adverse influence of depression and anxiety, assessed at the time of first myocardial infarction and 6 months later, on the physical aspect of HRQoL 12 months after the infarction.

METHOD

In all, 260 in-patients, admitted following first myocardial infarction, completed the Hospital Anxiety and Depression Scale and the Medical Outcomes Study SF-36 assessment before discharge and at 6- and 12-month follow-up.

RESULTS

Depression and anxiety 6 months after myocardial infarction predicted subsequent impairment in the physical aspects of HRQoL (attributable adjusted R(2)=9%, P<0.0005). These negative effects of depression and anxiety on outcome were mediated by feelings of fatigue. Depression and anxiety present before myocardial infarction did not predict HRQoL 12 months after myocardial infarction.

CONCLUSIONS

Detection and treatment of depression and anxiety following myocardial infarction improve the patient's health-related quality of life.

Depression and health-promoting lifestyles of persons with mental illnesses

This descriptive study examined relationships between depression, health-promoting lifestyles, and physical illnesses in a sample of persons living in the community who self-reported being diagnosed with mental illnesses. Variables of age, gender, and participation in psychiatric rehabilitation services were investigated to determine significant relationships to depression and lifestyles. Fifty adults completed a demographic survey, the CES-Depression scale, and the Health-Promoting Lifestyle Profile II. The findings emphasize the importance of psychiatric nurses assessing health-promoting lifestyles comprehensively in persons with serious mental illnesses and facilitating changes to improve both physical and mental health.

An international study comparing the effect of medically explained and unexplained somatic symptoms on psychosocial outcome

OBJECTIVE

Cross-sectional studies show an association between somatic symptoms and psychiatric morbidity in primary care. However, medically explained and unexplained symptoms have been considered separately as distinct and unrelated. In addition, data on outcome in primary care are equivocal. We compare the effect of both constructs (medically explained and unexplained symptoms) on psychiatric morbidity and disability (social and physical) at 1 year follow-up.

METHOD

Of 5447 patients presenting for primary care in 14 countries, 3201 participants were followed up (72% compliance). We measured physical, psychiatric, and social status using standardised instruments.

RESULTS

Patients with five or more somatic symptoms had increased psychosocial morbidity and physical disability at follow-up, even after controlling for confounders such as sociodemographics and recognition or treatment by general practitioners. There was little difference in outcome between medically explained and unexplained symptoms.

CONCLUSIONS

Somatic symptoms-irrespective of aetiology-are associated with adverse psychosocial and functional outcome in diverse cultures.
