Decrements in health-related quality of life associated with adverse events in people with diabetes.

ABSTRACT:

Aim

To estimate the decrements in health-related quality of life (QoL) associated with a range of adverse events to inform assessments of the effects of diabetes treatments on QoL in contemporary clinical practice.

Methods

Participants' QoL utility measures were derived from the five-level EuroQoL five-dimensional (EQ-5D-5L) questionnaires completed by 11 683 ASCEND participants (76% of 15 480 recruited). EQ-5D utility decrements associated with cardiovascular (myocardial infarction, coronary revascularization, transient ischaemic attack [TIA], ischaemic stroke, heart failure), bleeding (gastrointestinal [GI] bleed, intracranial haemorrhage, other major bleed), cancer (GI tract cancer, non-GI tract cancer), and microvascular events (end-stage renal disease [ESRD], amputation) were estimated using a linear regression model following adjustment for participants' sociodemographic and clinical risk factors.

Results

Amputation was associated with the largest EQ-5D utility decrement (-0.206), followed by heart failure (-0.185), intracranial haemorrhage (-0.164), GI bleed (-0.091), other major bleed (-0.096), ischaemic stroke (-0.061), TIA (-0.057), and non-GI tract cancer (-0.026). We were unable to detect decrements in EQ-5D utility associated with myocardial infarction, coronary revascularization, GI tract cancer, or ESRD. EQ-5D utility was lower at older age, independent of other factors.

Conclusion

These estimated decrements in QoL associated with cardiovascular, bleeding, cancer, and other adverse events can inform assessments of the overall value of treatments in patients with diabetes.

Project description:ObjectiveHealth utility decrements associated with diabetes mellitus complications are essential for calculating quality-adjusted life-years (QALYs) in patients for use in economic evaluation of diabetes interventions. Previous studies mostly focused on assessing the impact of complications on health utility at event year based on cross-sectional data. This study aimed to separately estimate health utility decrements associated with current and previous diabetes complications.Research design and methodsThe Health Utilities Index Mark 3 (HUI-3) was used to measure heath utility in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial (N = 8713). Five macrovascular complications (myocardial infarction [MI], congestive heart failure [CHF], stroke, angina, and revascularization surgery [RS]) and three microvascular complications (nephropathy [renal failure], retinopathy [severe vision loss], and neuropathy [severe pressure sensation loss]) were included in a set of alternative modelling approaches including the ordinary least squares (OLS) model, fixed effects model, and random effects model to estimate the complication-related health utility decrements.ResultsAll macrovascular complications were associated with decrements of HUI-3 scores: MI (event year: - 0.042, successive years: - 0.011), CHF (event year: - 0.089, successive years: - 0.041), stroke (event year: - 0.204, successive years: - 0.101), angina (event year: - 0.010, successive years: - 0.032), and revascularization (event year: - 0.038, successive years: - 0.016) (all p < 0.05). For microvascular complications, severe vision loss (- 0.057), and severe pressure sensation loss (- 0.066) were significantly associated with decrements of HUI-3 scores (both p < 0.05). Hypoglycemia (both severe and symptomatic) was found to be associated with a 0.036 decrement of health utility at event year, and a 0.033 decrement of health utility at successive years. Results from an OLS model are preferred for supporting a microsimulation model while a fixed effects model is preferred to describe direct health impacts from complications.ConclusionsMacrovascular and microvascular complications caused QALY decrements in patients with type 2 diabetes. While only part of the total impaired QALY is experienced during the event year, further QALY decrements for successive years were quite substantial.

Project description:PurposeThe health-related quality of life (HRQoL) of patients completing multidrug-resistant tuberculosis (MDR-TB) treatment in Namibia and whether the occurrence of adverse events influenced patients' rating of their HRQoL was evaluated.Patients and methodsA cross-sectional analytic survey of patients completing or who recently completed MDR-TB treatment was conducted. The patients rated their HRQoL using the simplified Short Form-™ (SF-8) questionnaire consisting of eight Likert-type questions. Three supplemental questions on the adverse events that the patients may have experienced during their MDR-TB treatment were also included. Scoring of HRQoL ratings was norm-based (mean =50, standard deviation =10) ranging from 20 (worst health) to 80 (best health), rather than the conventional 0-100 scores. We evaluated the internal consistency of the scale items using the Cronbach's alpha, performed descriptive analyses, and analyzed the association between the patients' HRQoL scores and adverse events.ResultsOverall, 36 patients (20 males, 56%) aged 17-54 years (median =40 years) responded to the questionnaire. The median (range) HRQoL score for the physical component summary was 58.6 (35.3-60.5), while the median score for the mental component summary was 59.3 (26.6-61.9), indicating not-so-high self-rating of health. There was good internal consistency of the scale scores, with a Cronbach's alpha value of >0.80. In all, 32 (89%) of the 36 patients experienced at least one adverse drug event of any severity during their treatment (median events =3, range 1-6), of which none was life-threatening. The occurrence of adverse events was not related to HRQoL scores. For patients reporting zero to two events, the median (range) HRQoL score was 56.8 (44.4-56.8), while for those reporting three or more events, the median score was 55.2 (38.6-56.8); P=0.34 for difference between these scores.ConclusionPatients completing treatment for MDR-TB in Namibia tended to score moderately low on their HRQoL, using the generic SF-8 questionnaire. The occurrence of adverse events did not lead to lower HRQoL scores upon treatment completion.

Project description:BackgroundPotentially inappropriate prescribing (PIP) describes medications where risk generally outweighs benefit for older people. Cross-sectional studies suggest an association between PIP and poorer health outcomes but there is a paucity of prospective cohort studies. This study investigates the longitudinal association of PIP with adverse drug events (ADEs), health related quality of life, and accident & emergency visits.MethodsStudy design: Two-year (2010-2012) prospective cohort study (n = 904, ≥70 years, community-dwelling) with linked pharmacy dispensing data.ExposureBaseline PIP: Screening Tool for Older Persons potentially Inappropriate Prescriptions (STOPP) and Beers 2012 applied 12 months prior.Study outcomesADEs (patient interview), health related quality of life (EQ-5D-3L: patient questionnaire), and accident & emergency visits (general practice medical record review).Statistical analysisDescriptive statistics: Poisson (incidence rate ratio [95% confidence interval [CI]], linear regression models [regression coefficient [95% CI]], and logistic [odds ratio [OR] [95% CI]).ResultsOf 791 participants eligible for follow-up, 673 (85%) returned a questionnaire and 605 (77%) also completed an ADE interview. Baseline STOPP PIP prevalence was 40% and 445 (74%) patients reported ≥1 ADE at follow-up. In multivariable analysis, ≥2 STOPP PIP was associated with ADEs (adjusted incidence rate ratio: 1.29 [95% CI 1.03, 1.85; p = .03]; poorer health related quality of life [adjusted regression coefficient: -0.11 [95% CI -0.16, -0.06; p < .001]]; and, ≥1 accident & emergency visit [adjusted OR: 1.85 [95% CI 1.06, 3.24; p = .03]]). Baseline Beers 2012 prevalence was 26% and there was no association with adverse health outcomes in multivariable analysis.ConclusionsOlder community-dwelling people, prescribed ≥2 STOPP PIP are more likely to report ADEs, poorer health related quality of life and attend the accident & emergency department over 2-year follow-up.
