Validation of the Disease-Specific Components of the Kidney Disease Quality of Life-36 (KDQOL-36) in Chinese Patients Undergoing Maintenance Dialysis

AIM

The aim of this study was to evaluate the validity, reliability and sensitivity of the disease-specific items of the Kidney Disease Quality of Life-36 (KDQOL-36) in Chinese patients undergoing maintenance dialysis.

METHODS

The content validity was assessed by content validity index (CVI) in ten subjects. 356 subjects were recruited for pilot psychometric testing. The internal construct validity was assessed by corrected item-subscale total correlation. Confirmatory factor analysis (CFA) was used to confirm the factor structure. The convergent validity was assessed by Pearson's correlation test between the disease specific subscale scores and SF-12 version 2 Health Survey (SF-12 v2) scores. The reliability was assessed by the internal consistency (Cronbach's Alpha coefficient) and 2-week test-retest reliability (intraclass correlation coefficient (ICC)). The sensitivity was determined by performing known group comparisons by independent t-test.

RESULTS

The CVI on clarity and relevance was ≥ 0.9 for all items. Corrected item- total correlation scores were ≥0.4 for all, except an item related to problems with access site. CFA confirmed the 3-factor structure of the disease-specific component of the KDQOL-36. The correlation coefficients between the disease-specific domain scores and the SF-12 v2 physical and mental component summary scores ranged from 0.328 to 0.492. The reliability was good (Cronbach's alpha coefficients ranged from 0.810 to 0.931, ICC ranged from 0.792 to 0.924). Only the effect subscale was sensitive in detecting differences in HRQOL between haemodialysis and peritoneal dialysis patients, with effect size = 0.68.

CONCLUSION

The disease-specific items of the KDQOL-36 are a valid, reliable and sensitive measure to assess the health-related quality of life of Chinese patients on maintenance dialysis.

Simple non-laboratory- and laboratory-based risk assessment algorithms and nomogram for detecting undiagnosed diabetes mellitus

BACKGROUND

The aim of the present study was to develop a simple nomogram that can be used to predict the risk of diabetes mellitus (DM) in the asymptomatic non-diabetic subjects based on non-laboratory- and laboratory-based risk algorithms.

METHODS

Anthropometric data, plasma fasting glucose, full lipid profile, exercise habits, and family history of DM were collected from Chinese non-diabetic subjects aged 18-70 years. Logistic regression analysis was performed on a random sample of 2518 subjects to construct non-laboratory- and laboratory-based risk assessment algorithms for detection of undiagnosed DM; both algorithms were validated on data of the remaining sample (n = 839). The Hosmer-Lemeshow test and area under the receiver operating characteristic (ROC) curve (AUC) were used to assess the calibration and discrimination of the DM risk algorithms.

RESULTS

Of 3357 subjects recruited, 271 (8.1%) had undiagnosed DM defined by fasting glucose ≥7.0 mmol/L or 2-h post-load plasma glucose ≥11.1 mmol/L after an oral glucose tolerance test. The non-laboratory-based risk algorithm, with scores ranging from 0 to 33, included age, body mass index, family history of DM, regular exercise, and uncontrolled blood pressure; the laboratory-based risk algorithm, with scores ranging from 0 to 37, added triglyceride level to the risk factors. Both algorithms demonstrated acceptable calibration (Hosmer-Lemeshow test: P = 0.229 and P = 0.483) and discrimination (AUC 0.709 and 0.711) for detection of undiagnosed DM.

CONCLUSION

A simple-to-use nomogram for detecting undiagnosed DM has been developed using validated non-laboratory-based and laboratory-based risk algorithms.

A systematic review of quality of thyroid-specific health-related quality-of-life instruments recommends ThyPRO for patients with benign thyroid diseases

OBJECTIVES

To appraise the measurement properties of thyroid-specific health-related quality-of-life (HRQOL) instruments and to provide recommendations on the choice of HRQOL instruments.

STUDY DESIGN AND SETTING

Systematic review of English-language literature published between 1993 and 2015 identified psychometric studies involving patients with thyroid disease through a search of Pubmed, Web of Science, Embase, and OVID MEDLINE. HRQOL instruments were graded on methodological quality and overall levels of evidence using a COSMIN checklist.

RESULTS

After a review of 742 original studies, 23 studies reporting 14 standardized HRQOL instruments targeted for Graves' ophthalmopathy (n = 4), hypothyroidism (n = 3), thyroid cancer (n = 2), other thyroid disease (n = 3), and nonthyroid tumor sites (n = 2) were identified. Hypothesis testing was evaluated most frequently. The 84-item thyroid-specific patient-reported outcome measure (ThyPRO) and 16-item Graves' ophthalmopathy-specific Quality-of-Life (GO-QOL) instruments were the most extensively evaluated instrument. The highest number of positive ratings in overall level of psychometric evidence was found in ThyPRO, GO-QOL, and 11-item Thyroid Treatment Satisfaction Questionnaire (ThyTSQ) instruments.

CONCLUSION

The ThyPRO is recommended for the assessment of HRQOL in patients with benign thyroid diseases while measurement properties of GO-QOL and ThyTSQ are satisfactory in measuring HRQOL of patients with Graves' ophthalmopathy and hypothyroidism, respectively.

Cost-Effectiveness of a Short Message Service Intervention to Prevent Type 2 Diabetes from Impaired Glucose Tolerance

Aims. To investigate the costs and cost-effectiveness of a short message service (SMS) intervention to prevent the onset of type 2 diabetes mellitus (T2DM) in subjects with impaired glucose tolerance (IGT). Methods. A Markov model was developed to simulate the cost and effectiveness outcomes of the SMS intervention and usual clinical practice from the health provider's perspective. The direct programme costs and the two-year SMS intervention costs were evaluated in subjects with IGT. All costs were expressed in 2011 US dollars. The incremental cost-effectiveness ratio was calculated as cost per T2DM onset prevented, cost per life year gained, and cost per quality adjusted life year (QALY) gained. Results. Within the two-year trial period, the net intervention cost of the SMS group was $42.03 per subject. The SMS intervention managed to reduce 5.05% onset of diabetes, resulting in saving $118.39 per subject over two years. In the lifetime model, the SMS intervention dominated the control by gaining an additional 0.071 QALY and saving $1020.35 per person. The SMS intervention remained dominant in all sensitivity analyses. Conclusions. The SMS intervention for IGT subjects had the superiority of lower monetary cost and a considerable improvement in preventing or delaying the T2DM onset. This trial is registered with ClinicalTrials.gov NCT01556880.

Can HbA1c replace OGTT for the diagnosis of diabetes mellitus among Chinese patients with impaired fasting glucose?

BACKGROUND

HbA1c ≥ 6.5% has been recommended as a diagnostic criterion for the detection of diabetes mellitus (DM) since 2010 because of its convenience, stability and significant correlation with diabetic complications. Nevertheless, the accuracy of HbA1c compared to glucose-based diagnostic criteria varies among subjects of different ethnicity and risk profile.

OBJECTIVES

This study aimed to evaluate the accuracy of HbA1c for diagnosing DM compared to the diagnosis by oral glucose tolerance test (OGTT) and the optimal HbA1c level to diagnose DM in primary care Chinese patients with impaired fasting glucose (IFG).

METHODS

A cross-sectional study was carried out in three public primary care clinics in Hong Kong. About 1128 Chinese adults with IFG (i.e. FG level between 5.6 and 6.9 mmol/l in the past 18 months) were recruited to receive paired OGTT and HbA1c tests. Sensitivities and specificities of HbA1c at different threshold levels for predicting DM compared to the diagnosis by OGTT were evaluated. A receiver operating characteristic (ROC) curve was used to determine the optimal cut-off level.

RESULTS

Among the 1128 subjects (mean age 64.2±8.9 year, 48.8% male), 229 (20.3%) were diagnosed to have DM by OGTT. The sensitivity and specificity of HbA1c ≥6.5% were 33.2% and 93.5%, respectively, for predicting DM diagnosed by OGTT. The area under the ROC curve was 0.770, indicating HbA1c had fair discriminatory power. The optimal cut-off threshold of HbA1c was 6.3% for discriminating DM from non-DM, with sensitivity and specificity of 56.3% and 85.5%, respectively. HbA1c ≥ 5.6% has the highest sensitivity and negative predictive value of 96.1% and 94.5%, respectively.

CONCLUSIONS

HbA1c ≥ 6.5% is highly specific in identifying people with DM, but it may miss the majority (66.8%) of the DM cases. An HbA1c threshold of <5.6% is more appropriate to be used for the exclusion of DM. OGTT should be performed for the confirmation of DM among Chinese patients with IFG who have an HbA1c between 5.6% and 6.4%.

Cost-effectiveness simulation and analysis of colorectal cancer screening in Hong Kong Chinese population: comparison amongst colonoscopy, guaiac and immunologic fecal occult blood testing

Background

The aim of this study was to evaluate the cost-effectiveness of CRC screening strategies from the healthcare service provider perspective based on Chinese population.

Methods

A Markov model was constructed to compare the cost-effectiveness of recommended screening strategies including annual/biennial guaiac fecal occult blood testing (G-FOBT), annual/biennial immunologic FOBT (I-FOBT), and colonoscopy every 10 years in Chinese aged 50 year over a 25-year period. External validity of model was tested against data retrieved from published randomized controlled trials of G-FOBT. Recourse use data collected from Chinese subjects among staging of colorectal neoplasm were combined with published unit cost data ($USD in 2009 price values) to estimate a stage-specific cost per patient. Quality-adjusted life-years (QALYs) were quantified based on the stage duration and SF-6D preference-based value of each stage. The cost-effectiveness outcome was the incremental cost-effectiveness ratio (ICER) represented by costs per life-years (LY) and costs per QALYs gained.

Results

In base-case scenario, the non-dominated strategies were annual and biennial I-FOBT. Compared with no screening, the ICER presented $20,542/LYs and $3155/QALYs gained for annual I-FOBT, and $19,838/LYs gained and $2976/QALYs gained for biennial I-FOBT. The optimal screening strategy was annual I-FOBT that attained the highest ICER at the threshold of $50,000 per LYs or QALYs gained.

Conclusion

The Markov model informed the health policymakers that I-FOBT every year may be the most effective and cost-effective CRC screening strategy among recommended screening strategies, depending on the willingness-to-pay of mass screening for Chinese population.

The effect of timing of incentive payments on response rates for cohort study telephone interviews in primary care setting with cost-minimization analysis, a randomized controlled trial

Background

The effect of timing of incentive payments on the response rate of telephone surveys is unknown. This study examined whether up-front or delayed incentive payments were associated with higher response rates for participation in a telephone interview administered longitudinal cohort study amongst primary care patients with lower urinary tract symptoms, and to compare the costs between the two timing methods.

Methods

This study was conducted as part of a naturalistic observation study on the health-related quality of life and health outcomes of Chinese primary care patients with lower urinary tract symptoms. The incentive payment was in the form of a supermarket gift voucher to the value of HD$50 (US$6.50) and could be used in lieu of cash at a major supermarket chain.720 subjects with lower urinary tract symptoms were randomly assigned into two groups. One group was offered an incentive of supermarket cash voucher at time of recruitment (‘up-front’ payment). The other group was told that the voucher would be sent to them after the complete of their 1-year follow-up telephone interview (‘delayed’ payment). Primary outcomes were the baseline and 1-year follow-up telephone survey response rates.

Results

There was no statistical difference in response rates at baseline (p-value = 0.938) or at the 1-year follow-up (p-value = 0.751) between groups. Cost per completed subject interviews for the up-front payment method was USD16.64, whilst cost for the delayed payment was USD 13.85.

Conclusions

It appears the timing of incentive payments does not affect response rates for telephone interview surveys conducted on primary care patients in Hong Kong at baseline or at 1-year follow-up. Delayed incentive payments can reduce the overall cost per successful case.

Increased number of structured diabetes education attendance was not associated with the improvement in patient-reported health-related quality of life: results from Patient Empowerment Programme (PEP)

AIMS

To assess the effect of a structured education intervention, Patient Empowerment Programme (PEP) patient-reported health-related quality of life (HRQOL) among type 2 diabetes mellitus (T2DM) patients, and if positive effect is confirmed, to further explore any association between frequency of sessions attendance and HRQOL.

METHODS

A total of 298 T2DM patients were recruited when they attended the first session of PEP, between March and September 2010, and were followed over a one-year period from baseline. HRQOL data were assessed using Short Form-12 Health Survey version 2 (SF-12) and Short Form-6 Dimension (SF-6D) at baseline and one-year follow-up. Individuals' anthropometric and biomedical data were extracted from an administrative database in Hong Kong. Unadjusted and adjusted analyses of linear regression models were performed to examine the impact of PEP session attendance on the change in the HRQOL scores, accounting for the socio-demographic and clinical characteristics at baseline.

RESULTS

Of the 298 eligible patients, 257 (86.2%) participated in the baseline assessment and 179 (60.1%) patients completed the follow-up assessment, respectively. Overall, PEP resulted in a significant improvement in SF-12 bodily pain and role emotional subscales and SF-6D utility scores. These positive changes were not associated with the level of participation as shown in both unadjusted and adjusted analyses.

CONCLUSIONS

The PEP made significant improvement in bodily pain, role emotional and overall aspects of HRQOL. Higher number of session attendance was not associated with improvement in HRQOL in primary care real-world setting. Key Messages ● Participants with type 2 diabetes mellitus who participated in structured diabetes education programme made significant improvement in bodily pain and role emotional subscales and SF-6D scores. ● There was no association between the number of sessions attended and any aspect of HRQOL.

Patterns of health-related quality of life and associated factors in Chinese patients undergoing haemodialysis

BACKGROUND

Haemodialysis (HD) is a life-saving but burdensome therapy for patients with end-stage renal disease (ESRD) which can have a detrimental impact on patients' quality of life and outcomes. There is currently little data on the health related quality of life (HRQOL) of Chinese ESRD patients undergoing HD and this study sought to examine the patterns of HRQOL and its associated factors within this population, as well as in comparison with the general local population.

METHODS

A cross-sectional study of 244 ESRD patients receiving HD in the hospital and in the community in Hong Kong was conducted using the Short Form-12 Health Survey version 2 (SF-12v2). All study subjects were one-to-one matched with subjects in a Hong Kong general population database by sex and exact age. Independent t-tests were performed to compare the mean SF-12v2 scores between HD patients and the general population, followed by one-way analysis of variance with post hoc Tukey's HSD tests to compare community-based haemodialysis, hospital-based haemodialysis and the general population. Multiple linear regressions were used to identify the factors (socio-demographic, clinical characteristics and comorbidities) associated with the HRQOL scores of ESRD patients receiving HD.

RESULTS

The SF-12v2 Physical Functioning, Role Physical, Bodily Pain, General Health and Physical Component Summary scores of HD patients were significantly lower than the age-sex adjusted general population. However, the SF-12v2 Mental Health and Mental Component Summary scores of HD patients were significantly higher than the corresponding general population. Poorer HRQOL was associated with being female, smoking, unemployment and hospital-based haemodialysis.

CONCLUSIONS

HD patients had substantially poorer physical HRQOL but better mental HRQOL than the age-sex adjusted general population. Patients receiving HD in the community setting had better HRQOL. Reasons for these observations will need to be further investigated. Those patients who are female, smokers and unemployed may warrant more attention as their poorer HRQOL may be associated with poorer outcomes.

Evaluation of the Effectiveness of Nurse-Led Continence Care Treatments for Chinese Primary Care Patients with Lower Urinary Tract Symptoms

Background

The aim of this study was to evaluate whether community-based nurse-led continence care interventions are effective in improving outcomes for adult Chinese primary care patients with lower urinary tract symptoms (LUTS).

Research Design and Subjects

A case-controlled intervention study was conducted. An intervention group of 360 primary care patients enrolled into a nurse-led continence care programme were recruited by consecutive sampling. A control group of 360 primary care patients with LUTS identified by screening were recruited from the waiting rooms of primary care clinics by consecutive sampling. Both groups were monitored at baseline and at 12 months.

Measures

Outcome measures included symptom severity, health-related quality of life (HRQOL), self-efficacy, global health and self-reported health service utilization at 12-months. The effect of the continence care programme on symptom severity and HRQOL was assessed by the difference-in-difference estimation, using independent t-test and multiple liner regression. Chi-square test was used to compare the self-efficacy, global health and self-reported health service utilization between the two groups at 12-months.

Results

After adjusting for baseline severity and socio-demographics, the intervention group had significant improvements in LUTS severity (P<0.05) and HRQOL (P<0.05). Improvements in the amount of urine leakage were not significantly different between the two groups. A higher proportion of subjects in the intervention group reported increased self-efficacy (43.48% vs. 66.83%), improved global health condition (17.74% vs. 41.5%), having doctor consultation (18.5% vs. 8.06), having medication due to LUTS (26.50% vs.11.29%) and having non-drug therapy due to LUTS (59.5% vs.9.68%).

Conclusions

Community-based nurse-led continence care can effectively alleviate symptoms, improve health-related quality of life, and enhance self-efficacy and the global health condition of Chinese male and female primary care patients with LUTS.

12-Month naturalistic outcomes of depressive disorders in Hong Kong's primary care

BACKGROUND

In Asia, the role of primary care physicians (PCPs) in mental health delivery is not clearly defined and what happens to patients following a depressive episode remains poorly understood.

OBJECTIVE

To examine the 12-month naturalistic outcomes of depression in primary care and the impact of PCP identification.

METHODS

A cohort study was conducted. A total of 10179 adults were consecutively recruited from the waiting rooms of 59 PCPs across Hong Kong to complete a survey which screened for depression. Blinded doctors provided data on their diagnosis and management; 539 screened-positive and 3819 screened-negative subjects consented to telephone follow-up at 3, 6 and 12 months. Study instruments included Patient Health Questionnaire-9, Centre for Epidemiologic Studies Depression Scale 20 and Short-Form Health Survey Version 2.0 (SF-12v2) and self-reported mental health and primary care service use.

RESULTS

12-month remission rate was 60.31%. PCP detection had no association with remission. Identified patients had poorer health-related quality of life (HRQOL) at baseline but a faster rate of recovery in SF-12v2 mental component scores. PCP detection was associated with greater mental health service use at 12, 26 and 52 weeks, while GP consultation rates were only increased at 12 weeks.

CONCLUSIONS

Over 1 year, ~60% of depressed patients experience symptom resolution, while 40% continue to suffer a chronic or remitting course of illness. Identification of depression by a PCP does not appear to affect remission of mood symptoms at 12 months, but is associated with a faster rate of recovery of HRQOL. PCP detection raises GP consultation rates temporarily however appears to enable more patients to access mental health services over 12 months.

Mental health of Chinese primary care patients with lower urinary tract symptoms

The aim of this study was to evaluate the mental health of Chinese primary care patients with lower urinary tract symptoms (LUTS). This was a cross-sectional observational study. Five hundred and nineteen subjects with LUTS completed a structured questionnaire containing the Depression, Anxiety, and Stress Scale-Short Form, the International Prostate Symptom Score, the adapted International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form and questions about socio-demographics. Overall, 17.7% of subjects reported depressive symptoms, 24.3% anxiety symptoms and 9.6% stress symptoms. In males, demographic factors associated with poorer mental health included being not married; clinical factors included higher LUTS severity, weak stream, straining and mixed urinary incontinence. In females, demographic factors associated with poorer mental health included being younger, not married and lower household income; clinical factors included higher LUTS severity, incomplete bladder emptying, urgency and weak stream. Chinese primary care patients with LUTS appear to be an at-risk group for poorer mental health with increased prevalence of anxiety and depressive symptoms and may require routine screening to identify those who may require more tailored interventions to address both their urinary symptoms and psychological distress.

The responsiveness of the International Prostate Symptom Score, Incontinence Impact Questionnaire-7 and Depression, Anxiety and Stress Scale-21 in patients with lower urinary tract symptoms

AIMS

To examine the responsiveness of a combined symptom severity and health-related quality of life measure, condition-specific health-related quality of life measure and mental health measure in patients with lower urinary tract symptoms.

BACKGROUND

To establish the responsiveness of measures that accurately capture the change in health status of patients is crucial before any longitudinal studies can be appropriately planned and evaluated.

DESIGN

Prospective longitudinal observational study.

METHODS

402 patients were surveyed at baseline and 1-year using the International Prostate Symptom Score, the Incontinence Impact Questionnaire-7 and Depression, Anxiety and Stress Scales-21. The internal and external responsiveness were assessed. Surveys were conducted from March 2013-July 2014.

RESULTS

In participants with improvements, the internal responsiveness for detecting positive changes was satisfactory in males and females for all scales, expect for the Depression subscale. The health-related quality of life question of the International Prostate Symptom Score was more externally responsive than the Incontinence Impact Questionnaire-7.

CONCLUSIONS

The International Prostate Symptom Score and Anxiety and Stress subscales were more responsive in males than in females. The symptom questions of the International Prostate Symptom Score and Anxiety and Stress subscales were not externally responsive in females. The health-related quality of life question of the International Prostate Symptom Score outperformed the Incontinence Impact Questionnaire-7 in both males and females, in terms of external responsiveness.

Mental Health Mediating the Relationship Between Symptom Severity and Health-Related Quality of Life in Patients with Lower Urinary Tract Symptoms

OBJECTIVES

Lower urinary tract symptoms (LUTS) can impact both mental health and health-related quality of life (HRQOL). To date, however, their associations with outcomes have only been examined in isolation and the interactive relationship between LUTS, mental health and HRQOL remains poorly understood. The aim of this study was to determine whether mental health mediates the relationship between LUTS severity and HRQOL.

METHODS

Five hundred and nineteen primary care subjects with LUTS completed a structured questionnaire including the International Prostate Symptom Score (IPSS), the adapted Incontinence Impact Questionnaire-7 (IIQ-7), the Chinese (HK) SF-12 Health Survey Version 2 (SF-12 v2) and the Depression, Anxiety and Stress Scale-21 (DASS-21). Mediation modeling was tested using Baron and Kenney's multistage regression approach and bootstrapping method.

RESULTS

Overall, mental health partially mediated the association between LUTS severity and HRQOL as measured by the SF-12 v2 physical component summary (PCS) and the IIQ-7. The depression, anxiety and stress scores all have similar mediation effects in the relationship between LUTS severity and HRQOL. Subgroup analysis by gender showed that anxiety fully mediated the relationship between LUTS severity and HRQOL as measured by the SF-12 v2 PCS in males whilst the mediation effects of mental health in the relationship between LUTS severity and HRQOL as measured by the SF-12 v2 PCS could not be found in females.

CONCLUSIONS

In order to enhance HRQOL, LUTS interventions should address the mental health of patients in addition to providing physical relief of symptoms.

Patient Empowerment Programme in primary care reduced all-cause mortality and cardiovascular diseases in patients with type 2 diabetes mellitus: a population-based propensity-matched cohort study

AIMS

To assess whether a structured diabetes education programme, the Patient Empowerment Programme (PEP), was associated with a lower risk of first cardiovascular disease (CVD) event and all-cause mortality in a population-based cohort of patients with type 2 diabetes mellitus (T2DM) in primary care.

METHODS

A Chinese cohort of 27 278 patients with T2DM and without previous CVD events on or before the baseline study recruitment date was linked to the Hong Kong administrative database from 2008 to 2013. The PEP was provided to patients with T2DM treated at primary care outpatient clinics through community trained professional educators. PEP non-participants were matched one-to-one with the PEP participants using a propensity score method with respect to their baseline covariates. Cox proportional hazard regression was performed to estimate the associations of the PEP with the occurrence of first CVD event, coronary heart disease, stroke, heart failure and death from any cause, controlling for baseline characteristics.

RESULTS

During a median of 21.5 months follow-up, 795 (352 PEP participants and 443 PEP non-participants) patients experienced a first CVD event. After adjusting for confounding variables, PEP participants had a lower rate of all-cause mortality [hazard ratio (HR) 0.564, 95% confidence interval (CI) 0.445-0.715; p < 0.001], first CVD (HR 0.807, 95% CI 0.696-0.935; p = 0.004) and stroke (HR 0.702; 95% CI 0.569-0.867; p = 0.001) than those without PEP.

CONCLUSIONS

Enrolment in the PEP was associated with lower all-cause mortality and a lower number of first CVD events among patients with T2DM. The CVD benefit of PEP might be attributable to improving metabolic control through empowerment of self-care and the enhancement of quality of diabetes care in primary care.

Help-seeking intentions and subsequent 12-month mental health service use in Chinese primary care patients with depressive symptoms

OBJECTIVE

To identify the factors associated with 12-month mental health service use in primary care patients with depressive symptoms.

DESIGN

Cross-sectional followed by 12-month cohort study.

SETTING AND PARTICIPANTS

10 179 adult patients were recruited from the waiting rooms of 59 primary care clinics across Hong Kong to complete a questionnaire which screened for depression. 518 screened-positive participants formed the cohort and were telephoned at 3, 6 and 12 months to monitor mental health service use.

PRIMARY AND SECONDARY OUTCOMES

▸ Help-seeking preferences; ▸ Intention to seek help from a healthcare professional; ▸ 12-month mental health service use.

RESULTS

At baseline, when asked who they would seek help from if they thought they were depressed, respondents preferred using friends and family (46.5%) over a psychiatrist (24.9%), psychologist (22.8%) or general practitioner (GP; 19.9%). The presence of depressive symptoms was associated with a lower intention to seek help from family and friends but had no effect on intention to seek help from a healthcare professional. Over 12 months, 24.3% of the screened-positive cohort reported receiving services from a mental health professional. Factors associated with service use included identification of depression by the GP at baseline, having a past history of depression or other mental illness, and being a public sector patient. Having a positive intention to seek professional help or more severe depressive symptoms at baseline was not associated with a greater likelihood of receiving treatment.

CONCLUSIONS

Mental health service use appears to be very low in this setting with only one in four primary care patients with depressive symptoms receiving treatment from a psychiatrist, GP or psychologist over a year. To help reduce the burden of illness, better detection of depressive disorders is needed especially for patients who may be undertreated such as those with no prior diagnosis of depression and those with more severe symptoms.

Road to better health and integration: a Delphi study on health service models for Hong Kong migrants

Introduction

In Hong Kong, migrants arriving from Mainland China often have multiple roles and responsibilities while adapting to new lives in their host destination. This paper explored the factors that contribute to the inequity in health services utilisation experienced by these migrants; and, identified the elements that could constitute an effective health delivery model to address the service gap.

Methods

Site visits and a focus group discussion (n = 13) were held with both public and private health providers before a number of innovative health delivery models were formulated. They were then circulated among the panel in two further rounds of Delphi survey (n = 11) from March-April 2012 to systematically collect opinions and select the most endorsed health service models to serve this target population.

Results

Focus group members perceived that most migrants were unaware of, or even ignored, their own physical and mental health needs, and had low utilisation of healthcare services, because of their pre-occupation with daily chores and hardship as well as differing health values, practices and expectations. They further identified that the structural issues such as the healthcare setting or the operation of current service provisions had failed to meet migrants’ health needs. Consequently, four new service models that incorporated professional advice and empowerment, which were identified as the two most important elements, were put forward. Thus, the model of having a nurse with social work training, supported by volunteer groups, was selected as the best option to familiarise and empower patients within the labyrinth of local healthcare services.

Conclusion

Implementation of a social empowerment model by way of targeted support and specific health information is recommended. Further evaluation of this model is needed to understand its effectiveness for improving health literacy and health status in this disadvantaged group in the long term.

Systematic review recommends the European Organization for Research and Treatment of Cancer colorectal cancer-specific module for measuring quality of life in colorectal cancer patients

OBJECTIVES

To critically appraise the measurement properties of standardized health-related quality of life (HRQOL) instruments for colorectal cancer (CRC) patients and to provide recommendations on the choice of HRQOL instruments.

STUDY DESIGN AND SETTING

Systematic review of English language literature published between January 1985 and May 2014 identified through a database search of PubMed, Web of Science, Embase, and Ovid MEDLINE. HRQOL instruments were rated on methodological quality and overall levels of evidence using a Consensus-based Standards for the selection of health Measurement Instrument checklist.

RESULTS

Internal consistency and hypothesis testing were evaluated most frequently in 63 studies identified. The Functional Assessment of Cancer Therapy-Colorectal (FACT-C) was the most extensively evaluated. The highest number of positive ratings in the overall level of evidence was found in the CRC-specific quality of life questionnaire module (QLQ-CR38) in European Organization for Research and Treatment of Cancer (EORTC) module, followed by the Memorial Sloan Kettering Cancer Center Bowel instrument, FACT-C, and Quick-FLIC. The EORTC QLQ-CR38 had the most positive ratings on measurement property and was recommended.

CONCLUSION

The EORTC QLQ-CR38 was recommended to assess HRQOL in patients with CRC, regardless of disease stage and primary tumor site.

Having a Family Doctor is Associated with Some Better Patient-Reported Outcomes of Primary Care Consultations

Background: Hong Kong (HK) has pluralistic primary care that is provided by a variety of doctors. The aim of our study was to assess patient-reported outcomes of primary care consultations in HK and whether having a family doctor (FD) made any difference.

Methods: We interviewed by telephone 3148 subjects from 5174 contacted households (response rate 60.8%) randomly selected from the general population of HK about the experience of their last primary care consultations in September 2007 and April 2008. We compared the patient-reported outcomes (PRO) and patient-centered process of care in those with a FD, those with other types of regular primary care doctors (ORD) and those without any regular primary care doctor (NRD). PRO included patient enablement, global improvement in health, overall satisfaction, and likelihood of recommending their doctors to family and friends. Patient-centered process of care indicators was explanations about the illness, and address of patient’s concerns.

Results: One thousand one hundred fifty, 746, and 1157 reported to have FD, ORD, and NRD, respectively. Over 80% of those with FD consulted their usual primary care doctors in the last consultation compared with 27% of those with NRD. Compared with subjects having ORD or NRD, subjects with FD reported being more enabled after the consultation and were more likely to recommend their doctors to family and friends. Subjects with FD and ORD were more likely than those having NRD to report a global improvement in health and satisfaction. FD group was more likely than the other two groups to report receiving an explanation on the diagnosis, nature, and expected course of the illness, and having their concerns addressed. Patient enablement was associated with explanation of diagnosis, nature, and expected course of illness, and address of patient’s concerns.

Conclusion: People with a regular FD were more likely to feel being enabled and to experience patient-centered care in consultations.
