Unrecognised psychological problems impair quality of life and increase consultation rates in Chinese elderly patients

Machine learning-based discrimination of unipolar depression and bipolar disorder with streamlined shortlist in adolescents of different ages

BACKGROUND

Variations in symptoms and indistinguishable depression episodes of unipolar depression (UD) and bipolar disorder (BD) make the discrimination difficult and time-consuming. For adolescents with high disease prevalence, an efficient diagnostic tool is important for the discrimination and treatment of BU and UD.

METHODS

This multi-center cross-sectional study involved 1587 UD and 246 BD adolescents aged 12-18. A combination of standard questionnaires and demographic information was collected for the construction of a full-item list. The unequal patient number was balanced with three data balancing algorithms, and 4 machine learning algorithms were compared for the discrimination ability of UD and BD in three age groups: all ages, 12-15 and 16-18. Random forest (RF) with the highest accuracy were used to rank the importance of features/items and construct the 25-item shortlist. A separate dataset was used for the final performance evaluation with the shortlist, and the discrimination ability for UD and BD was investigated.

RESULTS

RF performed the best for UD and BD discrimination in all 3 age groups (AUC 0.88-0.90). The most important features that differentiate UD from BD belong to Parental Bonding Instrument (PBI) and Loneliness Scale of the University of California at Los Angeles (UCLA). With RF and the 25-item shortlist, the diagnostic accuracy can still reach around 80 %, achieving 95 % of the accuracy levels obtained with all features.

CONCLUSIONS

Through machine learning algorithms, the most influencing factors for UD and BD classification were recombined and applied for rapid diagnosis. This highly feasible method holds the potential for convenient and accurate diagnosis of young patients in research and clinical practice.

Quality of life among patients with common mental disorders attending monk healers and primary care clinics in Thailand

Purpose

Common mental disorders are not only highly prevalent in primary health-care settings but also negatively affect patients’ quality of life (QoL). This study aims to assess the levels of QoL among patients with common mental disorders seeking care from a monk healer or primary care setting and to determine the comparative QoL of users in two different types of care settings in Thailand.

Design/methodology/approach

Consecutively attending clients or patients (N = 1251) of three faith healing or three health centres were assessed with measures of depression, anxiety and somatization disorder and QoL.

Findings

The overall QoL was 67.8 and among the four QoL domains, social QoL was the highest (72.3), followed by physical QoL (69.4), environmental QoL (64.8) and psychological QoL (64.6). In adjusted linear regression analyses, sociodemographic factors, such as higher educational level, being employed, having high debt and consulting a health centre, were associated with higher overall QoL. Compared to being a client with a monk healer, patients at a health centre had a higher overall QoL, environmental and psychological QoL. Having a general anxiety or major depressive disorder was negatively associated with overall QoL and all four QoL sub-domains, whereas somatization disorder was not associated with any QoL sub-domains.

Originality/value

To the best of the authors’ knowledge, this is the first study to investigate QoL in common mental disorder attenders with a monk healer in comparison with primary care patients. Primary care patients with a common mental disorder had significantly higher overall QoL (p<0.01), higher psychological QoL (p<0.001) and higher environmental QoL (p<0.001) than clients with a common mental disorder attending monk healers. This study extends previous research showing a negative association between anxiety and depressive disorders and QoL calling for integration of QoL in the management of common mental disorders in both complementary and public primary care in Thailand.

The effectiveness of a nurse-led short term life review intervention in enhancing the spiritual and psychological well-being of people receiving palliative care: A mixed method study

BACKGROUND

A life review is a promising intervention to enhance spiritual well-being in older people. Conventional life review interventions are lengthy and often led by psychologists.

OBJECTIVES

This is the first randomised controlled trial study to examine the effectiveness and applicability of a nurse-led short term life-review intervention in people with life limiting diseases, the purpose being to enhance their spiritual well-being and lower their anxiety and depression.

DESIGN

A sequential mixed method approach, randomised controlled trial and qualitative evaluation, was adopted. The intervention group received the short version life review, and the control group attention placebo. Participants were randomly assigned to either intervention or control groups by computerised randomisation. Both participants and outcome assessors were blinded to the group assignment.

SETTINGS

The study was conducted in three publicly funded regional hospitals in Hong Kong.

PARTICIPANTS

The target population were people suffering from life-limiting diseases, and receiving hospitalised, day hospice or outreach home care from the palliative care team.

METHODS

Two sets of questionnaires were used: the spiritual sub-scale of the McGill Quality of Life Questionnaire, Hong Kong version and the Hospital Anxiety and Depression Scale, Chinese version. The intervention process was assessed by means of observation log sheets and semi-structured interviews of 12 participants.

RESULTS

A total of 109 participants were recruited (54 in the intervention group, 55 in the control group). The intervention group showed significantly more improvement in spiritual well-being than the control group, with a Cohen's d-effect size of 0.65. Although there were improvements in both anxiety and depression levels in the intervention group, statistical significance in between-group comparisons was not reached. The process evaluation found that most participants were highly involved (92.6%), interested (77.8%) and participated in the intervention (79.6%). The participants described the intervention process as 'comfortable', 'relaxing' and 'interesting', and felt enlightened, with raised self-awareness, after it.

CONCLUSION

The nurse-led short term life-review intervention demonstrated significant improvement effects in spiritual well-being. Participant feedback on nurses' performance was positive, finding the intervention acceptable and useful. The setting of the intervention has now been extended from bedside to home. It is recommended to incorporate life review into palliative nursing specialty training, empowering more nurses to deliver the intervention in their daily practice.

Factors associated with consultation rates in general practice in England, 2013-2014: a cross-sectional study

Background

Workload in general practice has risen during the last decade, but the factors associated with this increase are unclear.

Aim

To examine factors associated with consultation rates in general practice.

Design and setting

A cross-sectional study examining a sample of 304 937 patients registered at 316 English practices between 2013 and 2014, drawn from the Clinical Practice Research Datalink.

Method

Age, sex, ethnicity, smoking status, and deprivation measures were linked with practice-level data on staffing, rurality, training practice status, and Quality and Outcomes Framework performance. Multilevel analyses of patient consultation rates were conducted.

Results

Consultations were grouped into three types: all (GP or nurse), GP, and nurse. Non-smokers consulted less than current smokers (all: rate ratio [RR] = 0.88, 95% CI = 0.87 to 0.89; GP: RR = 0.88, 95% CI = 0.87 to 0.89; nurse: RR = 0.91, 95% CI = 0.90 to 0.92). Consultation rates were higher for those in the most deprived quintile compared with the least deprived quintile (all: RR = 1.18, 95% CI = 1.16 to 1.19; GP: RR = 1.17, 95% CI = 1.15 to 1.19; nurse: RR = 1.13, 95% CI = 1.11 to 1.15). For all three consultation types, consultation rates increased with age and female sex, and varied by ethnicity. Rates in practices with >8 and ≤19 full-time equivalent (FTE) GPs were higher compared with those with ≤2 FTE GPs (all: RR = 1.26, 95% CI = 1.06 to 1.49; GP: RR = 1.36, 95% CI = 1.19 to 1.56).

Conclusion

The analyses show consistent trends in factors related to consultation rates in general practice across three types of consultation. These data can be used to inform the development of more sophisticated staffing models, and resource allocation formulae.

Caring burden of REM sleep behavior disorder - spouses' health and marital relationship

OBJECTIVES

Idiopathic REM sleep behavior disorder (iRBD) is noxious due to the high prevalence of sleep-related injuries to patients and their bed-partners. In this study, we aimed to investigate the impact of patients' RBD symptoms on their spouses, in terms of the quality of sleep, and physical, mental and marital aspects.

METHOD

A cross-sectional study comparing spouses of iRBD patients to the spouses of the age-and-sex-matched OSAS patients.

RESULTS

40 iRBD patients and their spouses (patients' age 66.6 ± 9.1, male 90%; spouses' age 62.9 ± 7.5), and 35 OSAS patients and their spouses (patients' age 67.8 ± 8.7 years old, male 80%; spouses' age 64.1 ± 9.1) were recruited. Almost all iRBD spouses (90%) reported disturbances by the nocturnal RBD behavioral symptoms of their bedpartners. About two-thirds (62.5%, N = 25) of the iRBD spouses reported a history of being injured during sleep. Spouses of both iRBD and OSAS patients reported a comparably high prevalence of insomnia, anxiety and depressive symptoms. Spouses of iRBD patients, however, reported more impaired quality of life and marital relationship. Nearly two-thirds of RBD couples continued co-sleeping, despite the risk of sleep-related injuries and nocturnal disturbances.

CONCLUSIONS

Both iRBD and OSAS spouses exhibited a high prevalence of insomnia and mood problems. In particular, iRBD significantly and negatively affect the spouses' quality of life and the marital relationship. Optimization of iRBD treatment, proper diagnosis, and management of sleep and mental health aspects of spouses may help to lessen the caring burden.

Coping with Depression in Single Black Mothers

Very little information exists in the literature about what black women do when they experience symptoms of depression. The purpose of this descriptive study was to analyze the responses of 208 community-residing black single mothers, aged 18 to 45, to an open-ended question asking, "What do you do to feel better when you are feeling down in the dumps?" The theoretical bases of the Ways of Coping Checklist, were used to facilitate categorizing their responses into a coping scale and then a particular coping profile. Percentages were used to categorize the frequency of the responses into the respective coping scale and to categorize the frequency of the combined responses of each woman into a respective coping profile. Of the 333 responses that the women provided, 327 were useable. Findings indicated that a majority of responses fell into the Escape-Avoidance category (n = 206; 63%), followed by the Seeking Social Support (n = 60, 18.3%), Positive Reappraisal (n = 40; 12.2%), Planful Problem Solving (n = 12; 3.7%), Distancing (n = 3; 1%), and Self-Controlling (n = 6; 1.8%) categories. No responses fit the Confrontive Coping or Accepting Responsibility categories and none of the responses indicated that the women sought professional help. Of the 176 women who provided answers to the study question, more than half (64.2%; n = 113) gave only emotion-focused responses, 2.8% (n = 5) gave only problem-focused responses, 2.8% (n = 5) gave mixed responses, and 30.2% (n = 53) reported social support seeking. Implications for future research, cultural theory, and nursing practice are addressed.

Outcomes of Depression in Black Single Mothers

Despite suggestions in the literature that depression has serious consequences, few studies have examined specific health and psychosocial outcomes of depression in Black single mothers. The purpose of this study was to estimate paths in a just-identified theoretical model of outcomes of depression for Black single mothers based on theoretical propositions and empirical findings. The model included the variables, depressive cognitions, depressive symptomatology, perceived social support, and positive health practices. Five direct and two indirect hypothesized relationships were estimated using structural equation modeling. A nonprobability sample of convenience of 159 Black single mothers aged 18 to 45 years was recruited for the study. This study used a cross-sectional correlational design. The participants responded in person or via the U.S. mail to the Center for Epidemiologic Studies-Depression scale, the Depressive Cognition Scale, the Personal Resource Questionnaire 85-Part 2, and the Personal Lifestyle Questionnaire. Beta and Gamma path coefficients were statistically significant for four out of five hypothesized direct relationships within the model ( p < .01). The direct path between depressive cognitions and positive health practices was not supported (Gamma = -.11, p > .05). The two indirect paths were weak but statistically significant ( p < .01). Depressive symptoms and perceived social support were outcomes of depressive cognitions. Positive health practices was not a direct outcome of depressive cognitions. Perceived social support and positive health practices were outcomes of depressive symptoms.

Prevention of anxiety and depression in Chinese: a randomized clinical trial testing the effectiveness of a stepped care program in primary care

BACKGROUND

Despite empirical evidence demonstrating the effectiveness of collaborative stepped care program (SCP) in Western countries, such programs have not been evaluated in the east, which has a different services system structure and cultural nuances in seeking help for mental illness. Furthermore, only a few studies have used SCP for depression and anxiety prevention. We conducted a trial to test its effectiveness in preventing major depressive disorder and generalized anxiety disorder among primary care patients with subthreshold depression and/or anxiety in Hong Kong.

METHODS

Subthreshold depression and/or anxiety patients were randomized into the SCP group (n=121) or care as usual (CAU) group (n=119). The SCP included watchful waiting, telephone counseling, problem solving therapy, and family doctor treatment within one year. The primary outcome was the onset of major depressive disorder or generalized anxiety disorder in 15 months. The secondary outcomes were depressive and anxiety symptoms, quality of life and time absent from work due to any illness.

RESULTS

Survival analysis showed no differences between the SCP and CAU groups (the cumulative probability of onset at 15 month was 23.1% in the SCP group and 20.5% in the CAU group; Hazard Ratio=1.62; 95% Confidence Interval: 0.82-3.18; p=0.16). No significant differences were found in secondary outcomes.

LIMITATIONS

Sample size might not have been large enough.

CONCLUSIONS

SCP did not show beneficial effect on depression/anxiety prevention compared with CAU in Hong Kong primary care. As a large majority of patients improved overtime without any intervention, we are not able to exclude the possibility that the intervention might be effective. Future studies would need to have a larger sample size and conduct on patients with more severe symptoms or perform a second screening.

Association between life events and change in depressive symptoms in Hong Kong Chinese elderly

BACKGROUND

Life event was regarded as an important risk factor for depression. Only a few prospective studies had examined the impact of life events individually and in combination. This study examined the relationship between life events and change in depressive symptoms.

METHODS

Depressive symptoms were assessed longitudinally using Geriatric Depression Scale (GDS) in 2630 community-dwelling Chinese elderly aged 65 or above. A cutoff score of 8 or higher indicated clinically relevant depressive symptoms. Subjects identified as demented were excluded. Eight life events experienced in the past year were assessed at 2year follow up. Logistic regression analyses were performed with adjustments for baseline GDS score and potential confounders such as sociodemographic, developmental and social factors, alcohol consumption, medical history and physical health status.

RESULTS

In men, experience of two events (OR=2.493) and three or more events (OR=3.199) was independently associated with increased risk of having depression. In women, the risk increased only in experiencing three or more events (OR=5.558). Moreover, life event affected depressive symptoms differently for men and women. Loss of pet and serious financial trouble were associated with an increase in depressive symptoms among men, but serious illness or accident of partner, and loss of a hobby were significant among women. Experience in either good or bad important events increased risk of depression in both sexes.

LIMITATIONS

The main limitation was all subjects were ambulatory volunteers.

CONCLUSIONS

The occurrence of single life event had contributed to the onset of depression and multiple events had a cumulative effect.

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.

Brief problem-solving treatment in primary care (PST-PC) was not more effective than placebo for elderly patients screened positive of psychological problems

OBJECTIVES

To evaluate whether screening followed by brief problem-solving treatment by primary care doctors (PST-PC) could improve health-related quality of life (HRQOL) and reduce consultation rates in the elderly.

DESIGN

A single-blind randomized placebo controlled trial (RCT).

SETTING

Two government funded primary care clinics in Hong Kong.

PARTICIPANTS

Two hundred and ninety nine Chinese patients aged 60 years or over, with positive screening scores for psychological problems by the Hospital Anxiety and Depression Scale (HADS).

INTERVENTIONS

One hundred and forty nine subjects were randomized to receive brief PST-PC from primary care doctors (treatment) and 150 to group video-viewing (placebo). All subjects were followed up by telephone at 6, 12, 26 and 52 weeks.

MAIN OUTCOME MEASURES

Changes in SF-36 HRQOL scores, HADS scores and monthly consultation rates were compared within and between groups.

RESULTS

Study completion rates were 69-71%. There was significant improvement in the SF-36 role-emotional (RE) and mental component summary (MCS) scores at week 6 in the PST-PC group but not in the placebo group. Several SF-36 scores improved significantly in the placebo (video) group at week 6-52. Mixed effects analysis adjusting for baseline values and cofounders did not show any difference in any of the outcomes between the PST-PC and placebo (video) groups.

CONCLUSIONS

Screening followed by brief PST-PC was associated with a short-term improvement in HRQOL in Chinese elderly patients screened positive of psychological problems, but the HRQOL benefit was not greater than those found in the placebo group who participated in group-viewings of health education videos.
