Reduced Rate of Acute Diabetes Events with Flash Glucose Monitoring Is Sustained for 2 Years After Initiation: Extended Outcomes from the RELIEF Study

Background: The RELIEF study has previously shown a fall in the rate of acute diabetes events (ADEs) in people living with type 1 diabetes (PwDT1) or people living with type 2 diabetes (PwDT2) in the 12 months after initiation of flash glucose monitoring (FLASH) in France. The 2-year follow-up has provided new insights on the frequency of ADEs, including severe hypoglycemia and diabetic ketoacidosis (DKA), during use of FLASH. Methods: The RELIEF study included 31,446 PwDT1 and 41,027 PwDT2 with a first delivery of FreeStyle Libre (FSL) between August 1 and December 31, 2017. Hospitalizations for DKA, severe hypoglycemia, diabetes-related coma, and hyperglycemia were recorded for the 12 months before and 24 months after FSL initiation. Persistence of the FSL system use was estimated through a Kaplan-Meier survival curve. Change in usual blood glucose monitoring was estimated through acquisition of blood glucose test strips. Results: In the 2 years after FSL initiation, hospitalizations for ADEs were reduced by 49% and by 48% in PwDT1 or PwDT2, respectively, driven by reductions in DKA. After 2 years, 88% of patients persisted with the system and estimated mean consumption of blood glucose test strips had fallen after 2 years by -82% and by -84% in type 1 diabetes mellitus and type 2 diabetes mellitus, respectively. Conclusion: Use of FSL consistently reduces the rates of hospitalization for ADEs, mainly DKA, 2 years after initiation, confirming this is not a transitory effect. Use of FSL also results in a clear and progressive drop in use of blood glucose test strips over the 2-year period.

[Is the prevalence of rheumatoid arthritis truly on the rise?]

A growing number of health insurance data analyses show an increase in the prevalence of rheumatoid arthritis (RA) in Germany. The studies refer to the claims diagnosis of RA, which is more frequent in recent years compared to earlier periods. Depending on the case definition, the numbers vary between 0.6% and 1.4% of the adult population. In this paper, the different studies are reviewed with regard to their data sources, the case definitions of RA and the frequency of the diagnosis. Due to the lack of clinical validation, the prevalence cannot be precisely determined from claims data.

Associations between shared care and patient experiences among older cancer survivors

PURPOSE

Cancer survivors have unique medical care needs. "Shared care," delivered by both oncologists and primary care providers (PCPs), may better address these needs. Little information is available on differences in outcomes among survivors receiving shared care versus oncologist-led or PCP-led care. This study compared experiences of care for survivors receiving shared care, oncologist-led, PCP-led, or other care patterns.

METHODS

We used SEER-CAHPS data, including NCI's SEER registry data, Medicare claims, and Medicare Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey responses. Medicare Fee-for-Service beneficiaries age ≥ 65 years in SEER-CAHPS with breast, cervical, colorectal, lung, renal, or prostate cancers or hematologic malignancies who responded to a Medicare CAHPS survey ≥ 18 months post-diagnosis were included. CAHPS measures included ratings of overall care, personal doctor, specialist physician, health plan, prescription drug plan, and five composite scores. Survivorship care patterns were identified using proportions of oncologist, PCP, and other physician encounters. Multivariable regressions examined associations between care patterns and CAHPS outcomes.

RESULTS

Among 10,132 survivors, 15% received shared care, 10% oncologist-led, 33% PCP-led, and 42% other. Compared with shared care, we found no significant differences in experiences of care except for getting needed drugs (lower scores for PCP-led and other care patterns). Sensitivity analyses using different patterns of care definitions similarly showed no associations between survivorship care pattern and experience of care.

CONCLUSIONS

Within the limitations of the study dataset, survivors age 65+ receiving shared care reported similar experiences of care to those receiving oncologist-led, PCP-led, and other patterns of care.

IMPLICATIONS FOR CANCER SURVIVORS

Shared care may not provide survivor-perceived benefits compared with other care patterns.

Persistence with Basal Insulin and Frequency of Hypoglycemia Requiring Hospitalization in Patients with Type 2 Diabetes

INTRODUCTION

A second-generation basal insulin analogue insulin glargine 300 U/mL (Gla-300) has been marketed in France since June 2016. This real-world study was designed to assess persistence with Gla-300 and the prevalence of related hypoglycemia requiring hospitalization as compared to first-generation basal insulins, in patients with type 2 diabetes mellitus (T2DM).

METHODS

A retrospective study was conducted using data in the large French comprehensive national healthcare system claims databases. Patients with T2DM newly treated with insulin in 2016 and 2017 (2-year period) were included. Three basal insulins [Gla-300, glargine 100 U/mL (Gla-100; both branded and biosimilar) and insulin detemir (IDet)] were compared for (1) persistence until treatment discontinuation using adjusted Cox models and (2) hypoglycemia requiring hospitalization over the period of insulin exposure.

RESULTS

During the 2-year study period, in France, 181,263 patients initiated basal insulin therapy (in a basal scheme or a more complex insulin scheme), of whom 74% initiated Gla-100, 14.2% initiated IDet and 11.8% initiated Gla-300. Patient characteristics varied according to the insulin regimen in terms of age, gender, social coverage, insulin scheme, and Charlson Comorbidity Index. Overall, 72% of patients were still treated with any basal insulin after 1 year (75% in basal scheme). In all insulin treatment regimens, patients were less likely to discontinue Gla-300 as compared to Gla-100 [adjusted odds ratio (OR) 0.39, 95% confidence interval (CI) 0.37-0.41], with similar results when only the basal scheme was considered (adjusted OR 0.38, 95% CI 0.35-0.40). Persistence with IDet was similar to that with Gla-100. Patients treated with Gla-100 had higher crude hospitalization rates for hypoglycemia than those receiving Gla-300 (1.4 for 100 patients-years; OR 0.67, 95% CI 0.55-0.81); however, this difference was not statistically significant after adjustment for patient characteristics. Emergency Room (ER) visits were less frequent in patients treated with Gla-300 versus Gla-100 with or without adjustment for patient characteristics (p < 0.0001).

CONCLUSION

Real-world persistence for basal insulin therapy in patients with T2DM was significantly better in those on Gla-300 compared with those on Gla-100 and IDet. A trend to a lower frequency of hospitalization for hypoglycemia and ER visits, whatever the cause, was also observed in patients on Gla-300.

Classification of patients with incident non-specific low back pain: implications for research

BACKGROUND CONTEXT

Comparing research studies of low back pain is difficult because of heterogeneity. There is no consensus among researchers on inclusion criteria or the definition of an episode.

PURPOSE

This study aimed to determine pattern(s) of recurrent non-specific low back pain from data collected over 27 months.

STUDY DESIGN/SETTING

This study used retrospective cohort study using administrative claims from multiple payers. Although claims are designed for capturing costs, not clinical complexity, they are valid for describing utilization patterns, which are not affected by potential "upcoding."

PATIENT SAMPLE

The patient sample consisted of population-based, nationally generalizable sample of 65,790 adults with continuous medical and pharmaceutical commercial health insurance who received health care for incident, non-specific low back pain. Potential subjects were excluded for plausible cause of the pain, severe mental illness, or cognitive impairment.

OUTCOME MEASURES

Diagnostic and therapeutic health-care services, including medical, surgical, pharmaceutical, and complementary, received in inpatient, outpatient, and emergency settings were the outcome measures for this study.

METHODS

The methods used for this study were latent class analysis of health-care utilization over 27 months (9 quarters) following index diagnosis of non-specific low back pain occurring in January-March 2009 and an analysis sample with 60% of subjects (n=39,597) and validation sample of 40% (n=26,193).

RESULTS

Four distinct groups of patients were identified and validated. One group (53.4%) of patients recovered immediately. One third of patients (31.7%) may appear to recover over 6 months, but maintain a 37-48% likelihood of receiving care for low back pain in every subsequent quarter, implying frequent relapse. Two remaining groups of patients each maintain very high probabilities of receiving care in every quarter (65-78% and 84-90%), predominantly utilizing therapeutic services and pain medication, respectively. Probabilistic grouping relative to alternatives was very high (89.6-99.3%). Grouping was not related to demographic or clinical characteristics.

CONCLUSIONS

The four distinct sets of patient experiences have clear implications for research. Inclusion criteria should specify incident or recurrent cases. A 6-month clean period may not be sufficiently long to assess incidence. Reporting should specify the proportion recovering immediately to prevent mean recovery rates from masking between-group differences. Continuous measurement of pain or disability may be more reliable than measuring outcomes at distinct endpoints.
