The associations of body mass index with physical and mental aspects of health-related quality of life in Chinese patients with type 2 diabetes mellitus: Results from a cross-sectional survey

Background: This study aimed to determine the associations of various clinical factors with generic health-related quality of life (HRQOL) scores among Hong Kong Chinese patients with type 2 diabetes mellitus (T2DM) in the outpatient primary care setting using the short-form 12 (SF-12).Methods: A cross-sectional survey of 488 Chinese adults with T2DM recruited from a primary care outpatient clinic was conducted from May to August 2008. Data on the standard Chinese (HK) SF-12 Health Survey and patients' socio-demographics were collected from face-to-face interviews. Glycaemic control, body mass index (BMI), chronic co-morbidities, diabetic complications and treatment modalities were determined for each patient through medical records. Associations of socio-demographic and clinical factors with physical component summary (PCS-12) and mental component summary scores (MCS-12) were evaluated using multiple linear regression.Results: The socio-demographic correlates of PCS-12 and MCS-12 were age, gender and BMI. After adjustment for socio-demographic variables, the BMI was negatively associated with PCS-12 but positively associated with MCS-12. The presence of diabetic complications was associated with lower PCS-12 (regression coefficient:-3.0 points, p < 0.05) while being on insulin treatment was associated with lower MCS-12 (regression coefficient:-5.8 points, p < 0.05). In contrast, glycaemic control, duration of T2DM and treatment with oral hypoglycaemic drugs were not significantly associated with PCS-12 or MCS-12.Conclusions: Among T2DM subjects in the primary care setting, impairments in the physical aspect of HRQOL were evident in subjects who were obese or had diabetic complications whereas defects in the mental aspect of HRQOL were observed in patients with lower BMI or receiving insulin injections. © 2013 Wong et al.; licensee BioMed Central Ltd.published_or_final_versio

A qualitative study of patients' views on quality of primary care consultations in Hong Kong and comparison with the UK CARE Measure

&lt;b&gt;Background&lt;/b&gt; Patients' priorities and views on quality care are well-documented in Western countries but there is a dearth of research in this area in the East. The aim of the present study was to explore Chinese patients' views on quality of primary care consultations in Hong Kong and to compare these with the items in the CARE measure (a process measure of consultation quality widely used in the UK) in order to assess the potential utility of the CARE measure in a Chinese population.&lt;p&gt;&lt;/p&gt; &lt;b&gt;Methods&lt;/b&gt; Individual semi-structured interviews were conducted on 21 adult patients from 3 different primary care clinics (a public primary healthcare clinic, a University health centre, and a private family physician's clinic). Topics discussed included expectations, experiences, and views about quality of medical consultations. Interviews were typed verbatim, and a thematic approach was taken to identify key issues. These identified issues were then compared with the ten CARE measure items, using a CARE framework: Connecting (Care Measure items 1–3), Assessing (item 4), Responding (items 5,6), and Empowering (items 7–10).&lt;p&gt;&lt;/p&gt; &lt;b&gt;Results&lt;/b&gt; Patients judged doctors in terms of both the process of the consultation and the perceived outcomes. Themes identified that related to the interpersonal process of the consultation fitted well under the CARE framework; Connecting and communicating (18/21 patients), Assessing holistically (10/21 patients), Responding (18/21 patients) and Empowering (19/21 patients). Patients from the public clinic, who were generally of lower socio-economic status, were least likely to expect holistic care or empowerment. Two-thirds of patients also judged doctors on whether they performed an adequate physical examination, and three-quarters on the later outcomes of consultation (in terms of relief or cure and/or side-effects of prescribed drugs).&lt;p&gt;&lt;/p&gt; &lt;b&gt;Conclusion&lt;/b&gt; These findings suggest that Chinese patients in Hong Kong value engaged, empathic primary care doctors and judge the quality of consultations largely on these human skills and the attitudes and values that underpin them, as well as on the perceived outcomes of treatment. The match between themes relating to consultation process and the CARE Measure items suggests utility of this measure in this population, but further quantitative validation is required

A short message service (SMS) intervention to prevent diabetes in Chinese professional drivers with pre-diabetes: A pilot single-blinded randomized controlled trial

Aim: To determine the efficacy of delivering short-message service (SMS) to provide diabetes-related information in reducing the risk of developing diabetes in Chinese professional drivers with pre-diabetes. Methods: A pilot single-blinded randomized controlled trial was conducted in Hong Kong between 05/2009 and 04/2012. Professional drivers with impaired glucose tolerance (IGT) were randomly allocated to either a SMS group receiving messages comprising knowledge and lifestyle modification on diabetes or to a control group with usual care. Primary outcomes were the incidence rate of diabetes mellitus over 12 and 24 months period. Results: Fifty-four, out of 104 professional drivers recruited, were randomly allocated to intervention group. Fewer subjects developed diabetes at 12 months in intervention group (5.56%) compared to control group (16.00%). Relative risk (RR) of diabetes onset was 0.35 (95%CI: 0.10-1.24) and the number needed to treat (NNT) for preventing one diabetes was 9.57. At 24 months, RR increased to 0.62 (95%CI: 0.24-1.61) with a NNT of 10.58. Logistic regression showed a significant odds ratio of 0.04 (P= 0.021) for intervention group compared to control group at 12-month follow-up for completers and a non-significant odds ratio of 0.34 (P= 0.303) at 24-month follow-up. Conclusions: The SMS program proved to have potential to reduce the risk of developing diabetes at 12 months but additional measures should be integrated to prevent or delay disease progression. © 2013 Elsevier Ireland Ltd.link_to_subscribed_fulltex

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$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
