Wang Y, Xu Y, Shan H, Pan H, Chen J, Yang J. Health state utility values of type 2 diabetes mellitus and related complications: a systematic review and meta-regression. Health Qual Life Outcomes 2024; 22:74. [PMID: 39244536 PMCID: PMC11380328 DOI: 10.1186/s12955-024-02288-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2024] [Accepted: 08/26/2024] [Indexed: 09/09/2024] Open
Abstract
BACKGROUND This study aimed to synthesize and quantitatively examine Health State Utility Values (HSUVs) for Type 2 Diabetes Mellitus (T2DM) and its complications, providing a robust meta-regression framework for selecting appropriate HSUV estimates. METHOD We conducted a systematic review to extract HSUVs for T2DM and its complications, encompassing various influencing factors. Relevant literature was sourced from a review spanning 2000-2020, supplemented by literature from PubMed, Embase, and the Web of Science (up to March 2024). Multivariate meta-regression was performed to evaluate the impact of measurement tools, tariffs, health status, and clinical and demographic variables on HSUVs. RESULTS Our search yielded 118 studies, contributing 1044 HSUVs. The HSUVs for T2DM with complications varied, from 0.65 for cerebrovascular disease to 0.77 for neuropathy. The EQ-5D-3L emerged as the most frequently employed valuation method. HSUV differences across instruments were observed; 15-D had the highest (0.89), while HUI-3 had the lowest (0.70) values. Regression analysis elucidated the significant effects of instrument and tariff choice on HSUVs. Complication-related utility decrement, especially in diabetic foot, was quantified. Age <70 was linked to increased HSUVs, while longer illness duration, hypertension, overweight and obesity correlated with reduced HSUVs. CONCLUSION Accurate HSUVs are vital for the optimization of T2DM management strategies. This study provided a comprehensive data pool for HSUVs selection, and quantified the influence of various factors on HSUVs, informing analysts and policymakers in understanding the utility variations associated with T2DM and its complications.

Changes in quality of life following hypoglycaemia in adults with type 2 diabetes: A systematic review of longitudinal studies. Diabet Med 2022; 39:e14706. [PMID: 34596292 PMCID: PMC9293422 DOI: 10.1111/dme.14706] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Accepted: 09/28/2021] [Indexed: 12/21/2022]
Abstract
AIM To conduct a systematic review of published studies reporting on the longitudinal impacts of hypoglycaemia on quality of life (QoL) in adults with type 2 diabetes. METHOD Database searches with no restrictions by language or date were conducted in MEDLINE, Cochrane Library, CINAHL and PsycINFO. Studies were included for review if they used a longitudinal design (e.g. cohort studies, randomised controlled trials) and reported on the association between hypoglycaemia and changes over time in patient-reported outcomes related to QoL. RESULTS In all, 20 longitudinal studies published between 1998 and 2020, representing 50,429 adults with type 2 diabetes, were selected for review. A descriptive synthesis following Synthesis Without Meta-analysis guidelines indicated that self-treated symptomatic hypoglycaemia was followed by impairments in daily functioning along with elevated symptoms of generalised anxiety, diabetes distress and fear of hypoglycaemia. Severe hypoglycaemic events were associated with reduced confidence in diabetes self-management and lower ratings of perceived health over time. Frequent hypoglycaemia was followed by reduced energy levels and diminished emotional well-being. There was insufficient evidence, however, to conclude that hypoglycaemia impacted sleep quality, depressive symptoms, general mood, social support or overall diabetes-specific QoL. CONCLUSIONS Longitudinal evidence in this review suggests hypoglycaemia is a common occurrence among adults with type 2 diabetes that impacts key facets in the physical and psychological domains of QoL. Nonetheless, additional longitudinal research is needed-in particular, studies targeting diverse forms of hypoglycaemia, more varied facets of QoL and outcomes assessed using hypoglycaemia-specific measures.

Abstract
AIM Hypoglycaemia affects many people with Type 2 diabetes using insulin and other glucose-lowering therapies. This systematic review examined the impact of severe hypoglycaemia (episodes requiring external assistance) on psychological outcomes (e.g. emotional well-being, health status and quality of life) in adults with Type 2 diabetes. METHODS MEDLINE Complete, PsycINFO and CINAHL databases were searched for peer-reviewed empirical studies, published in English, reporting the occurrence and severity of hypoglycaemia and its relationship with patient-reported outcomes (PROs) in adults with Type 2 diabetes. Data were extracted from published reports and analysed. RESULTS Of 3756 potentially relevant abstracts, 29 studies met the inclusion criteria. Most reported cross-sectional data and sample sizes varied widely (N = 71 to 17 563). Although definitions of mild and severe hypoglycaemia were largely consistent between studies, additional non-standard categorizations (e.g. moderate, very severe) were apparent and recall periods varied. Overall, severe hypoglycaemia was associated with increased fear of hypoglycaemia and decreased emotional well-being, health status and diabetes-specific quality of life. Effect sizes show that the association with fear of hypoglycaemia was stronger than with general health status. CONCLUSIONS Notwithstanding the limitations of the empirical studies, these findings indicate that severe hypoglycaemia in adults with Type 2 diabetes (insulin- and non-insulin-treated) is associated with impaired psychological outcomes. Healthcare professionals should address the psychological impact of severe hypoglycaemia during clinical consultations, to support individuals to minimize exposure to, and the psychological consequences of, severe hypoglycaemia.
