Prevalence and factors associated with diabetes-related distress in type 2 diabetes patients: a study in Hong Kong primary care setting.

Diabetes-related distress (DRD) refers to the psychological distress specific to living with diabetes. DRD can lead to negative clinical consequences such as poor self-management. By knowing the local prevalence and severity of DRD, primary care teams can improve the DRD evaluation in our daily practice. This was a cross-sectional study conducted in 3 General Out-patient Clinics (GOPCs) from 1 December 2021 to 31 May 2022. A random sample of adult Chinese subjects with T2DM, who regularly followed up in the selected clinic in the past 12 months, were included. DRD was measured by the validated 15-item Chinese version of the Diabetes Distress Scale (CDDS-15). An overall mean score ≥ 2.0 was considered clinically significant. The association of DRD with selected clinical and personal factors was investigated. The study recruited 362 subjects (mean age 64.2 years old, S.D. 9.5) with a variable duration of living with T2DM (median duration 7.0 years, IQR 10.0). The response rate was 90.6%. The median HbA1c was 6.9% (IQR 0.9). More than half (59.4%) of the subjects reported a clinically significant DRD. Younger subjects were more likely to have DRD (odds ratio of 0.965, 95% CI 0.937-0.994, p = 0.017). Patients with T2DM in GOPCs commonly experience clinically significant DRD, particularly in the younger age group. The primary care clinicians could consider integrating the evaluation of DRD as a part of comprehensive diabetes care.

Assessment of Hypertension Complications and Health Service Use 5 Years After Implementation of a Multicomponent Intervention.

Importance: There is a lack of information regarding the impact of implementing a protocol-driven, team-based, multicomponent intervention in public primary care settings on hypertension-related complications and health care burden over the long term. Objective: To compare hypertension-related complications and health service use at 5 years among patients managed with Risk Assessment and Management Program for Hypertension (RAMP-HT) vs usual care. Design, Setting, and Participants: In this population-based prospective matched cohort study, patients were followed up until the date of all-cause mortality, an outcome event, or last follow-up appointment before October 2017, whichever occurred first. Participants included 212 707 adults with uncomplicated hypertension managed at 73 public general outpatient clinics in Hong Kong between 2011 and 2013. RAMP-HT participants were matched to patients receiving usual care using propensity score fine stratification weightings. Statistical analysis was conducted from January 2019 to March 2023. Interventions: Nurse-led risk assessment linked to electronic action reminder system, nurse intervention, and specialist consultation (as necessary), in addition to usual care. Main Outcomes and Measures: Hypertension-related complications (cardiovascular diseases, end-stage kidney disease), all-cause mortality, public health service use (overnight hospitalization, attendances at accident and emergency department, specialist outpatient clinic, and general outpatient clinic). Results: A total of 108 045 RAMP-HT participants (mean [SD] age: 66.3 [12.3] years; 62 277 [57.6%] female) and 104 662 patients receiving usual care (mean [SD] age 66.3 [13.5] years; 60 497 [57.8%] female) were included. After a median (IQR) follow-up of 5.4 (4.5-5.8) years, RAMP-HT participants had 8.0% absolute risk reduction in cardiovascular diseases, 1.6% absolute risk reduction in end-stage kidney disease, and 10.0% absolute risk reduction in all-cause mortality. After adjusting for baseline covariates, the RAMP-HT group was associated with lower risk of cardiovascular diseases (hazard ratio [HR], 0.62; 95% CI, 0.61-0.64), end-stage kidney disease (HR, 0.54; 95% CI, 0.50-0.59), and all-cause mortality (HR, 0.52; 95% CI, 0.50-0.54) compared with the usual care group. The number needed to treat to prevent 1 cardiovascular disease event, end-stage kidney disease, and all-cause mortality was 16, 106, and 17, respectively. RAMP-HT participants had lower hospital-based health service use (incidence rate ratios ranging from 0.60 to 0.87) but more general outpatient clinic attendances (IRR, 1.06; 95% CI, 1.06-1.06) compared with usual care patients. Conclusions and Relevance: In this prospective matched cohort study involving 212 707 primary care patients with hypertension, participation in RAMP-HT was associated with statistically significant reductions in all-cause mortality, hypertension-related complications, and hospital-based health service use after 5 years.

Morbidity Patterns in Primary Care in Hong Kong: Protocol for a Practice-Based Morbidity Survey.

BACKGROUND: Up-to-date and accurate information about the health problems encountered by primary care doctors is essential to understanding the morbidity pattern of the community to better inform health care policy and practice. Morbidity surveys of doctors allow documentation of actual consultations, reflecting the patient's reason for seeking care as well as the doctor's diagnostic interpretation of the illness and management approach. Such surveys are particularly critical in the absence of a centralized primary care electronic medical record database. OBJECTIVE: With the changing sociodemographic profile of the population and implementation of health care initiatives in the past 10 years, the aim of this study is to determine the morbidity and management patterns in Hong Kong primary care during a pandemic and compare the results with the last survey conducted in 2007-2008. METHODS: This will be a prospective, practice-based survey of Hong Kong primary care doctors. Participants will be recruited by convenience and targeted sampling from both public and private sectors. Participating doctors will record the health problems and corresponding management activities for consecutive patient encounters during one designated week in each season of the year. Coding of health problems will follow the International Classification of Primary Care, Second Edition. Descriptive statistics will be used to calculate the prevalence of health problems and diseases as well as the rates of management activities (referral, investigation, prescription, preventive care). Nonlinear mixed effects models will assess the differences between the private and public sectors as well as factors associated with morbidity and management patterns in primary care. RESULTS: The data collection will last from March 1, 2021, to August 31, 2022. As of April 2022, 176 doctor-weeks of data have been collected. CONCLUSIONS: The results will provide information about the health of the community and inform the planning and allocation of health care resources. TRIAL REGISTRATION: ClinicalTrials.gov NCT04736992; https://clinicaltrials.gov/ct2/show/NCT04736992. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/37334.

Clinical Audit on Chronic Obstructive Pulmonary Disease (COPD) Management in Primary Care: A Quality Improvement Project from Hong Kong.

Objective: To enhance the quality of COPD management in primary care via a two-phase clinical audit in Hong Kong. Methods: COPD patients aged 40 or above and had attended any of the 73 public primary care clinics under the Hospital Authority of Hong Kong (HAHK) for follow up (FU) during the audit period were included. Performance of six evidence-based audit criteria on COPD care was reviewed in phase 1 from 1st April 2017 to 31st March 2018. Service gaps were identified and a series of quality improvement strategies were executed in the one-year implementation phase. The outcome of the service enhancement was assessed in phase 2 from 1st April 2019 to 31st March 2020. Student's t-test and the chi-square test were used to examine the statistically significant differences between the two phases. Results: Totally 10,385 COPD cases were identified in phase 1, the majority were male (87.7%) and the mean age was 75.3±9.9 years. Among the 3102 active smokers, 1788 (57.6%) were referred to receive the smoking cessation counselling and 1578 (50.9%) actually attended it. A total of 4866 cases (46.9%) received seasonal influenza vaccine (SIV) and 4227 cases (40.7%) received pneumococcal vaccine (PCV). A total of 1983 patients (19.1%) had spirometry test done before and 1327 patients (12.8%) had history of hospital admission due to acute exacerbation of COPD (AECOPD). After the proactive implementation phase, performance on all criteria was significantly improved in phase 2, with a marked increase in the SIV and PCV uptake rate and spirometry performance rate. Most importantly, a significant reduction in AECOPD rate leading to hospital admission had been achieved (9.6%, P<0.00001). Conclusion: COPD care at all public primary care clinics of HAHK had been significantly improved for all audit criteria via the systematic team approach, which, in turn, reduced the hospital admission rate and helped relieve the burden of the health care system.

A cluster-randomized study on the Risk Assessment and Management Program for home blood pressure monitoring in an older population with inadequate health literacy.

The Risk Assessment and Management Program (RAMP) has successfully demonstrated a reduction of blood pressure (BP) and cardiovascular (CVD) risk of patients with hypertension. This study aimed to compare the blood pressure control rate of participants after attended RAMP group, with those attended RAMP individual from usual care. A prospective open cluster-randomized controlled trial was performed in five public primary care clinics. Patients with uncontrolled hypertension were recruited. RAMP group consisted of multi-disciplinary group education on knowledge of hypertension, lifestyle modification, and hands-on home blood pressure monitoring (HBPM) training. Each participant was given a branchial HBPM device. An individual face-to-face nurse follow-up was arranged 6 weeks later. Participants' office BP and clinical parameters were assessed at 6, 12, and 18 months. Three RAMP group and two RAMP-individual clusters recruited 152 and 139 participants, respectively. The mean age was 67.0 (SD 9.9) year. After 18 months of treatment, there was a significantly higher BP control rate in the RAMP-group participants than the RAMP-individual participants (78.9% vs 36.5%, P < .001). The systolic BP was reduced by 19.7 mm Hg (95% CI -22.03, -17.40, P < .001) and diastolic BP by 8.1 mm Hg (95% CI -9.66, -6.61, P < .001) in RAMP group while the RAMP individual demonstrated 9.3 mm Hg (95% CI -12.1, -6.4, P < .001) reduction in systolic BP without any significant difference in diastolic BP. The RAMP-group participants' body weight (BW) and body mass index(BMI) had no significant changes, while the RAMP-individual participants had a significant increase in BW and BMI. No adverse effect was reported.

Can the colour of per-rectal bleeding estimate the risk of lower gastrointestinal bleeding caused by malignant lesion?

PURPOSE: To estimate the risk of lower gastrointestinal bleeding (LGIB) caused by malignant lesion in patients presenting with per-rectal bleeding (PRB), by using visual aid as an objective measurement of PRB colour. METHODS: This was a prospective observational study on patients presented with PRB to Family Medicine Specialty Clinic, who undergo flexible sigmoidoscopy (FS) or colonoscopy (CLN) from December 2012 to September 2013. Patients aged 40 years old or above, haemodynamically stable, with normal haemoglobin level were included. Patients with a history of previous colonic surgery, refused to have FS or CLN, with ophthalmologic diseases such as colour blindness were excluded. Parameters including subjective description of PRB colour, number of chosen red colour by patients, source and distance of bleeding from anal verge were recorded for analysis. Receiver operating characteristic (ROC) curve was used to identify the optimal cutoff level of colour for diagnosing colonic lesion. Diagnostic accuracy was assessed by area under the ROC curve (AUC). Accountability of this model was assessed by logistic regression. RESULTS: The dark PRB colour was associated with diagnosis of tumour (p < 0.001) and advanced neoplastic polyp (p < 0.001). The light PRB colour was associated with the diagnosis of piles (p < 0.001). The performance of our model to predict tumour or advanced neoplastic polyps by colour (AUC, 0.798) had a better discriminative power than that to predict colonic lesion alone (AUC, 0.610) by ROC curve analysis. CONCLUSION: Objective measurement of PRB colour accurately estimated the risk of LGIB caused by malignant lesion in patients presenting with PRB.

Association of more negative attitude towards commencing insulin with lower glycosylated hemoglobin (HbA1c) level: a survey on insulin-naïve type 2 diabetes mellitus Chinese patients.

BACKGROUND: Delay in commencing insulin among type 2 Diabetes Mellitus (DM) patients is common.  One of the reasons is patients' psychological insulin resistance, which is particularly prevalent in Chinese patients. This study examined the correlation between socio-demographic and clinical characteristics; and attitudes towards commencing insulin in Chinese primary care patients. METHOD: A cross-sectional survey was conducted on 303 insulin-naïve Type 2 DM patients recruited from 15 primary care clinics across Hong Kong using the Chinese Attitudes to Starting Insulin Questionnaire (Ch-ASIQ). Subject selection criteria were patients on maximal oral anti-diabetes treatment who needed to commence insulin therapy. Linear regression was used to identify correlations between age, sex, educational level, occupation, body mass index, diabetes disease duration, laboratory test indicating disease control and biochemical markers including glycosylated hemoglobin (HbA1c) level, low density lipoprotein level and estimated glomeruli filtration rate, and presence of diabetic complications with the four sub-scales (self-image and stigmatization; factors promoting self-efficacy; fear of pain or needles; time and family support ) and the overall Ch-ASIQ score. RESULTS: The most prevalent negative attitude was 'fear of needle injections' (70.1 %). The most common positive attitude was 'I can manage the skill of injecting insulin' (67.5 %). The mean Ch-ASIQ score of 2.50 (S.D. = 0.38) was equal to the mid-score, which signified an overall ambivalent attitude among the study population. Women scored significantly higher in the fear of pain or needles subscale (p = 0.011) and had an overall more negative attitude towards commencing insulin (p = 0.016). Subjects with lower HbA1c levels also had a significantly lower Ch-ASIQ sum score (p = 0.048) indicating a more negative attitude towards commencing insulin. CONCLUSION: In Chinese primary care patients with Type 2 DM, the need to commence insulin was associated with a number of negative emotions, which lead to a lower motivation to accept treatment. Perception of need as indicated by HbA1c level may be an important influencing factor determining a patient's overall attitude towards starting insulin. Fortunately, in our setting, the injection technique does not appear to be a major barrier. However, needle fears are common, especially amongst women. Target interventions to acknowledge and help them to overcome their fears are essential before insulin treatment is commenced.

Progression from impaired fasting glucose to type 2 diabetes mellitus among Chinese subjects with and without hypertension in a primary care setting.

BACKGROUND: The progression from impaired fasting glucose (IFG) to type 2 diabetes mellitus (T2DM) in Chinese subjects, with and without hypertension, in a primary care setting was unknown. METHODS: The present retrospective multicenter 5-year (2002-2007) cohort study was performed on IFG subjects attending 23 general outpatient clinics who were identified by their elevated fasting blood glucose laboratory results. Development of T2DM was determined by physician diagnosis of T2DM or starting of oral antidiabetic drugs within 5 years. The relationship between the time of T2DM diagnosis and subject characteristics was assessed by adjusted hazard ratios (aHR) from Cox hazards model. RESULTS: Of the 9161 IFG subjects, 4080 (45%) were men and 5081 (55%) were women. There were 1998 subjects who developed T2DM. The 5-year cumulative incidence was 0.218, whereas the overall annual incidence rate was 5.981/100 person-years. Subjects were more likely to develop T2DM if they were hypertensive (aHR = 1.44; 95% confidence interval [CI] 1.28-1.62; P < 0.001), aged <60 years (aHR = 1.36, 95% CI 1.24-1.49; P < 0.001), female (aHR = 1.18, 95% CI 1.08-1.29; P < 0.001), and had higher fasting glucose levels (6.39 ± 0.49 vs 6.24 ± 0.43 mmol/L in the group that developed T2DM vs the group without T2DM, respectively; aHR = 2.01, 95% CI 1.83-2.20; P < 0.001). CONCLUSION: Overall, more than one-fifth of IFG subjects in the primary care setting developed T2DM within 5 years. Health care professionals can target interventions to patients with risk factors for disease progression.

A fibroid or cancer? A rare case of mixed choriocarcinoma and epithelioid trophoblastic tumour.

Background. Gestational trophoblastic disease (GTD) is a rare complication of pregnancy which is characterised by abnormal growth of the trophoblasts at the placental site. It is categorised into benign and malignant forms, which include hydatidiform moles (HMs) and gestational trophoblastic neoplasia (GTN), respectively. A mixed choriocarcinoma (CC) and epithelioid trophoblastic tumour (ETT) is an extremely rare subgroup of GTN, which is a highly curable but aggressive form of malignancy. Case. We report a case of mixed CC and ETT in a 41-year-old patient who presented with a 2-year history of menorrhagia and fibroid uterus in the absence of previous history of molar pregnancy. She had a 12-year interval between the antecedent pregnancy and presentation. She was treated with intensive regimen of adjuvant chemotherapy, etoposide, methotrexate, and actinomycin-D with etoposide and cisplatin (EMA-EP). She has remained disease free for more than 5 years. Conclusion. This case highlights the importance of considering GTN as one of the differential diagnoses value of ß -HCG in patients presented with menorrhagia and growing fibroids.
