Public and private healthcare services utilization by non-institutional elderly in Hong Kong: Is the inverse care law operating?

<b>Objectives</b> To assess the factors associated with healthcare services utilization by the non-institutional elderly across five types of service utilization (Western medicine doctors in Government clinics, private Western medicine doctors, Chinese medicine practitioners, Emergency Units, and hospitalization).<p></p> <b>Methods </b>A secondary data analysis of a territory-wide cross-sectional survey collected by the Government among a representative sample of 4812 elderly (aged 60 and above) in Hong Kong.<p></p> <b>Results</b> Our analysis, based on Anderson's behavioral framework, shows that need factors (relating to actual or perceived illness and diseases) are significantly related to the healthcare services utilization examined. However, enabling factors, such as monthly household income per capita, play a significant role in determining the utilization. Although the lower-income elderly consult more Government clinics and less private clinics than the more affluent, they have a lower total utilization of healthcare services despite having significantly greater healthcare needs.<p></p> <b>Conclusions </b>This suggests a mismatch of need and supply within the mixed economy of private and public healthcare services and suggests the existence of an 'inverse care law' in Hong Kong amongst elderly citizens. The findings raise concerns of inequities in Hong Kong's healthcare system, raising implications for future healthcare reforms

Perspective from health professionals on delivery of sub-acute care in Hong Kong: A qualitative study in a health system

Objectives The perception and understanding of health professionals of the role of sub-acute care in the health system will have an impact on the potential effectiveness in preventing unnecessary hospitalization. This study aims to explore the perceived role and quality of sub-acute care services in the context of Hong Kong from the perspective of health service providers and to identify barriers to effectiveness.Methods Seven focus groups were conducted and the discussion was led by a guide covering three main areas: definition/component/role of sub-acute, difficulties in the sub-acute care services provision, and suggestion for further improvement in the provision of sub-acute care.Results The participants highlighted the positive role of sub-acute to promote patient's health and quality of life so as to reduce unnecessary hospitalization. The potential barriers in the sub-acute care identified were interrelated and focused mainly on systemic issues including lack of service coordination, specialist input and resources. The participants also suggested a number of practical ways to improve the quality of sub-acute care services.Conclusions The findings showed a need for further improvement in the process of sub-acute care by developing operation guideline and re-evaluating the allocation of resources to support the sub-acute care provision.Sub-acute care Communication barrier Health professionals Healthcare system

Water conservation overrides osmotic diuresis during SGLT2 inhibition in patients with heart failure

BACKGROUND: Sodium-glucose cotransporter 2 inhibitors are believed to improve cardiac outcomes due to their osmotic diuretic potential. OBJECTIVES: The goal of this study was to test the hypothesis that vasopressin-driven urine concentration overrides the osmotic diuretic effect of glucosuria induced by dapagliflozin treatment. METHODS: DAPA-Shuttle1 (Hepato-renal Regulation of Water Conservation in Heart Failure Patients With SGLT-2 Inhibitor Treatment) was a single-center, double-blind, randomized, placebo-controlled trial, in which patients with chronic heart failure NYHA functional classes I/II and reduced ejection fraction were randomly assigned to receive dapagliflozin 10 mg daily or placebo (1:1) for 4 weeks. The primary endpoint was change from baseline in urine osmolyte concentration. Secondary endpoints included changes in copeptin levels and solute free water clearance. RESULTS: Thirty-three randomized, sodium-glucose cotransporter 2 inhibitor-naïve participants completed the study, 29 of whom (placebo: n = 14; dapagliflozin: n = 15) provided accurate 24-hour urine collections (mean age 59 ± 14 years; left ventricular ejection fraction 31% ± 9%). Dapagliflozin treatment led to an isolated increase in urine glucose excretion by 3.3 mmol/kg/d (95% CI: 2.51-4.04; P < 0.0001) within 48 hours (early) which persisted after 4 weeks (late; 2.7 mmol/kg/d [95% CI: 1.98-3.51]; P < 0.0001). Dapagliflozin treatment increased serum copeptin early (5.5 pmol/L [95% CI: 0.45-10.5]; P < 0.05) and late (7.8 pmol/L [95% CI: 2.77-12.81]; P < 0.01), leading to proportional reductions in free water clearance (early: -9.1 mL/kg/d [95% CI: -14 to -4.12; P < 0.001]; late: -11.0 mL/kg/d [95% CI: -15.94 to -6.07; P < 0.0001]) and elevated urine concentrations (late: 134 mmol/L [95% CI: 39.28-229.12]; P < 0.01). Therefore, urine volume did not significantly increase with dapagliflozin (mean difference early: 2.8 mL/kg/d [95% CI: -1.97 to 7.48; P = 0.25]; mean difference late: 0.9 mL/kg/d [95% CI: -3.83 to 5.62]; P = 0.70). CONCLUSIONS: Physiological-adaptive water conservation eliminated the expected osmotic diuretic potential of dapagliflozin and thereby prevented a glucose-driven increase in urine volume of approximately 10 mL/kg/d · 75 kg = 750 mL/kg/d.
