Why don't diabetes patients achieve recommended risk factor targets? Poor adherence versus lack of treatment intensification.

ABSTRACT: Despite the availability of effective hypertension, hyperlipidemia, and hyperglycemia therapies, target levels of systolic blood pressure (SBP), LDL-cholesterol (LDL-c), and hemoglobin A1c control are often not achieved.To examine the relative importance of patient medication nonadherence versus clinician lack of therapy intensification in explaining above target cardiovascular disease (CVD) risk factor levels.Cross-sectional assessment.In 2005, 161,697 Kaiser Permanente Northern California adult diabetes patients were included in the study."Above target" was defined as most recent A1c >/=7.0% for hyperglycemia, LDL-c >/=100 mg/dL for hyperlipidemia, and SBP >/=130 mmHg for hypertension. Poor adherence was defined as medication gaps for >/=20% of days covered for all medications for each condition separately. Treatment intensification was defined as an increase in the number of drug classes, increased dosage of a class, or a switch to a different class within the 3 months before or after notation of above target levels.Poor adherence was found in 20-23% of patients across the 3 conditions. No evidence of poor adherence with no treatment intensification was found in 30% of hyperglycemia patients, 47% of hyperlipidemia patients, and 36% of hypertension patients. Poor adherence or lack of therapy intensification was evident in 53-68% of patients above target levels across conditions.Both nonadherence and lack of treatment intensification occur frequently in patients above target for CVD risk factor levels; however, lack of therapy intensification was somewhat more common. Quality improvement efforts should focus on these modifiable barriers to CVD risk factor control.

Project description:IntroductionIDegLira is a once-daily combination of insulin degludec (IDeg) and liraglutide. Trials directly comparing IDegLira with alternative strategies for intensifying basal insulin are ongoing. While awaiting results, this analysis compared indirectly how different strategies affected glycated hemoglobin (HbA1c) and other outcomes.MethodsA pooled analysis of five completed Novo Nordisk randomized clinical trials in patients with type 2 diabetes inadequately controlled on basal insulin was used to compare indirectly IDegLira (N = 199) with: addition of liraglutide to basal insulin (N = 225) [glucagon-like peptide-1 receptor agonist (GLP-1RA) add-on strategy]; basal-bolus (BB) insulin [insulin glargine (IGlar) + insulin aspart] (N = 56); or up-titration of IGlar (N = 329). A supplementary analysis was performed with the BB arm including patients who received IGlar or IDeg as basal insulin in the relevant trial (N = 210). All trials had comparable inclusion/exclusion criteria and baseline characteristics. Individual patient-level data were analyzed using multivariable statistical models with potential baseline heterogeneity accounted for using explanatory variables.ResultsAt end of study, differences between IDegLira and BB or up-titrated IGlar, respectively, were as follows: reduction in HbA1c -0.30%, 95% confidence interval (-0.58; -0.01) and -0.65% (-0.83; -0.47); change in body weight -6.89 kg (-7.92; -5.86) and -4.04 kg (-4.69; -3.40) all in favor of IDegLira. Confirmed hypoglycemia rate was 122.8 (90.7; 166.1), 1060.8 (680.2; 1654.4), and 286.1 (231.1; 354.1) events/100 patient-years for IDegLira, BB, and up-titrated IGlar, respectively. Odds ratios for achieving HbA1c <7.0%, <7.0% without hypoglycemia, and <7.0% without hypoglycemia and no weight gain were greater with IDegLira versus up-titrated IGlar. The supplementary analysis yielded similar results to the main analysis. Results with IDegLira were similar to those for the 'GLP-1RA add-on' arm.ConclusionThese results suggest that IDegLira may be more effective, with lower hypoglycemia rates and less weight gain, than up-titrated basal insulin or BB in patients uncontrolled on basal insulin.

Project description:BackgroundAdherence to cancer screening is important for cancer survivors because they are at high risk of subsequent cancer diagnoses or recurrence. We assessed adherence to breast, cervical, and colorectal cancer-(CRC)-screening guidelines and evaluated demographic disparities among a population-based sample of survivors.MethodsA representative sample of Utah survivors diagnosed from 2012-2018 with any reportable invasive cancer was selected from central cancer registry records for a survey about survivorship needs. We estimated the proportion of eligible survivors adhering to U.S. Preventive Services Task Force screening guidelines and calculated risk ratios and 95% confidence intervals. Analyses were age-adjusted and weighted to account for sample design and nonresponse.ResultsAnd 1421 survivors completed the survey (57.2% response rate). Screening adherence was 74.4% for breast, 69.4% for cervical, and 79.7% for CRC. Rural residents were more likely to adhere to breast cancer screening than urban residents (86.1% vs. 72.7%; adjusted RR = 1.19, CI = 1.05, 1.36). Higher educational attainment was associated with increased adherence to cervical and colorectal cancer screening. Younger age was associated with greater adherence to cervical cancer screening (p = 0.006) but lower adherence to CRC screening (p = 0.003). CRC screening adherence was lower among the uninsured and those without a primary care provider (45.6%) compared to those with a regular provider (83.0%; adjusted RR = 0.57, CI = 0.42, 0.79).ConclusionsSurveys based on samples from central cancer registries can provide population estimates to inform cancer control. Findings demonstrate work is needed to ensure all Utah cancer survivors obtain recommended cancer screenings. Efforts should focus particularly on increasing uptake of breast and cervical cancer screening and reducing demographic disparities in CRC screening.PrecisDespite high risk for subsequent cancer diagnosis, Utah cancer survivors are not all obtaining recommended breast, cervical, and colorectal cancer screenings. This presents a significant healthcare gap.

Project description:Introduction:Youth in Uganda are disproportionately impacted by HIV and report significant barriers to ART adherence. We asked participants how fixed versus flexible adherence target setting for incentive interventions, in combination with other support systems, could help HIV-positive youth in Uganda reach medication adherence targets. Methods:Four focus groups conducted in Luganda were audiotaped, transcribed, and translated into English; the transcriptions were then coded using Dedoose software. Two members of the research team read the text and identified the basic topics covered. A codebook was developed that detailed inclusion and exclusion criteria for each topic area, as well as typical entries for each code. A directed content analysis was used to identify key themes. Results:Several themes were common across groups. Participants consistently maintained that they preferred to set their own adherence targets. But regardless of how adherence targets were assigned, participants noted that missing their target was disappointing. They commented positively on the use of Medication Event Monitoring System (MEMS) caps, noting that knowing their adherence information was being tracked often encouraged them to take their medications. Participants reported that receiving text messages further motivated them to take their medications; however, on occasions when they reported not doing well, they wanted intensive follow-up by staff. Participants said that the prize drawing alone did not motivate their ART adherence and that receiving 'zero' in the drawing was disheartening. Conclusion:We found that participants preferred to set their own adherence targets and that doing so increased a sense of ownership in achieving them. All participants enjoyed using MEMS caps and expressed disappointment at needing to return the device at the study's completion. Participants noted that text message reminders may be a useful way to help patients stay motivated between clinic visits; however, ongoing engagement and support are needed from providers and counselors. Finally, our participants stressed the importance of including incentives with a small, positive value rather than 0 when designing the lowest prize.
