(2021) 2021. “Intensification of Diabetes Medications at Hospital Discharge and Clinical Outcomes in Older Adults in the Veterans Administration Health System.”. JAMA Network Open 4 (10): e2128998. https://doi.org/10.1001/jamanetworkopen.2021.28998.

IMPORTANCE: Transient elevations of blood glucose levels are common in hospitalized older adults with diabetes and may lead clinicians to discharge patients with more intensive diabetes medications than they were using before hospitalization.

OBJECTIVE: To investigate outcomes associated with intensification of outpatient diabetes medications at discharge.

DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study assessed patients 65 years and older with diabetes not taking insulin who were hospitalized in the Veterans Health Administration Health System between January 1, 2011, and September 28, 2016, for common medical conditions. Data analysis was performed from January 1, 2020, to March 31, 2021.

EXPOSURE: Discharge with intensified diabetes medications, defined as filling a prescription at hospital discharge for a new or higher-dose medication than was being used before hospitalization. Propensity scores were used to construct a matched cohort of patients who did and did not receive diabetes medication intensifications.

MAIN OUTCOMES AND MEASURES: Coprimary outcomes of severe hypoglycemia and severe hyperglycemia were assessed at 30 and 365 days using competing risk regressions. Secondary outcomes included all-cause readmissions, mortality, change in hemoglobin A1c (HbA1c) level, and persistent use of intensified medications at 1 year after discharge.

RESULTS: The propensity-matched cohort included 5296 older adults with diabetes (mean [SD] age, 73.7 [7.7] years; 5212 [98.4%] male; and 867 [16.4%] Black, 47 [0.9%] Hispanic, 4138 [78.1%] White), equally split between those who did and did not receive diabetes medication intensifications at hospital discharge. Within 30 days, patients who received medication intensifications had a higher risk of severe hypoglycemia (hazard ratio [HR], 2.17; 95% CI, 1.10-4.28), no difference in risk of severe hyperglycemia (HR, 1.00; 95% CI, 0.33-3.08), and a lower risk of death (HR, 0.55; 95% CI, 0.33-0.92). At 1 year, no differences were found in the risk of severe hypoglycemia events, severe hyperglycemia events, or death and no difference in change in HbA1c level was found among those who did vs did not receive intensifications (mean postdischarge HbA1c, 7.72% vs 7.70%; difference-in-differences, 0.02%; 95% CI, -0.12% to 0.16%). At 1 year, 48.0% (591 of 1231) of new oral diabetes medications and 38.5% (548 of 1423) of new insulin prescriptions filled at discharge were no longer being filled.

CONCLUSIONS AND RELEVANCE: In this national cohort study, among older adults hospitalized for common medical conditions, discharge with intensified diabetes medications was associated with an increased short-term risk of severe hypoglycemia events but was not associated with reduced severe hyperglycemia events or improve HbA1c control. These findings indicate that short-term hospitalization may not be an effective time to intervene in long-term diabetes management.

Journal of the American Geriatrics Society 69 (10): 2745-51. https://doi.org/10.1111/jgs.17329.

BACKGROUND/OBJECTIVES: Transitional care management (TCM) visits delivered following hospitalization have been associated with reductions in mortality, readmissions, and total costs; however, uptake remains low. We sought to describe trends in TCM visit delivery during the COVID-19 pandemic.

DESIGN: Cross-sectional study of ambulatory electronic health records from December 30, 2019 and January 3, 2021.

SETTING: United States.

PARTICIPANTS: Forty four thousand six hundred and eighty-one patients receiving transitional care management services.

MEASUREMENTS: Weekly rates of in-person and telehealth TCM visits before COVID-19 was declared a national emergency (December 30, 2019 to March 15, 2020), during the initial pandemic period (March 16, 2020 to April 12, 2020) and later period (April 12, 2020 to January 3, 2021). Characteristics of patients receiving in-person and telehealth TCM visits were compared.

RESULTS: A total of 44,681 TCM visits occurred during the study period with the majority of patients receiving TCM visits age 65 years and older (68.0%) and female (55.0%) Prior to the COVID-19 pandemic, nearly all TCM visits were conducted in-person. In the initial pandemic, there was an immediate decline in overall TCM visits and a rise in telehealth TCM visits, accounting for 15.4% of TCM visits during this period. In the later pandemic, the average weekly number of TCM visits was 841 and 14.0% were telehealth. During the initial and later pandemic periods, 73.3% and 33.6% of COVID-19-related TCM visits were conducted by telehealth, respectively. Across periods, patterns of telehealth use for TCM visits were similar for younger and older adults.

CONCLUSION: The study findings highlight a novel and sustained shift to providing TCM services via telehealth during the COVID-19 pandemic, which may reduce barriers to accessing a high-value service for older adults during a vulnerable transition period. Further investigations comparing outcomes of in-person and telehealth TCM visits are needed to inform innovation in ambulatory post-discharge care.

BACKGROUND: Closing loops to complete diagnostic referrals remains a significant patient safety problem in most health systems, with 65%-73% failure rates and significant delays common despite years of improvement efforts, suggesting new approaches may be useful. Systems engineering (SE) methods increasingly are advocated in healthcare for their value in studying and redesigning complex processes.

OBJECTIVE: Conduct a formative SE analysis of process logic, variation, reliability and failures for completing diagnostic referrals originating in two primary care practices serving different demographics, using dermatology as an illustrating use case.

METHODS: An interdisciplinary team of clinicians, systems engineers, quality improvement specialists, and patient representatives collaborated to understand processes of initiating and completing diagnostic referrals. Cross-functional process maps were developed through iterative group interviews with an urban community-based health centre and a teaching practice within a large academic medical centre. Results were used to conduct an engineering process analysis, assess variation within and between practices, and identify common failure modes and potential solutions.

RESULTS: Processes to complete diagnostic referrals involve many sub-standard design constructs, with significant workflow variation between and within practices, statistical instability and special cause variation in completion rates and timeliness, and only 21% of all process activities estimated as value-add. Failure modes were similar between the two practices, with most process activities relying on low-reliability concepts (eg, reminders, workarounds, education and verification/inspection). Several opportunities were identified to incorporate higher reliability process constructs (eg, simplification, consolidation, standardisation, forcing functions, automation and opt-outs).

CONCLUSION: From a systems science perspective, diagnostic referral processes perform poorly in part because their fundamental designs are fraught with low-reliability characteristics and mental models, including formalised workaround and rework activities, suggesting a need for different approaches versus incremental improvement of existing processes. SE perspectives and methods offer new ways of thinking about patient safety problems, failures and potential solutions.

(2021) 2021. “Preventability of 30-Day Hospital Revisits Following Admission With COVID-19 at an Academic Medical Center.”. Joint Commission Journal on Quality and Patient Safety 47 (11): 696-703. https://doi.org/10.1016/j.jcjq.2021.08.011.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic may have affected the preventability of 30-day hospital revisits, including readmissions and emergency department (ED) visits without admission. This study was conducted to examine the preventability of 30-day revisits for patients admitted with COVID-19 in order to inform the design of interventions that may decrease preventable revisits in the future.

METHODS: The study team retrospectively reviewed a cohort of adults admitted to an academic medical center with COVID-19 between March 21 and June 29, 2020, and discharged alive. Patients with a 30-day revisit following hospital discharge were identified. Two-physician review was used to determine revisit preventability, identify factors contributing to preventable revisits, assess potential preventive interventions, and establish the influence of pandemic-related conditions on the revisit.

RESULTS: Seventy-six of 576 COVID-19 hospitalizations resulted in a 30-day revisit (13.2%), including 21 ED visits without admission (3.6%) and 55 readmissions (9.5%). Of these 76 revisits, 20 (26.3%) were potentially preventable. The most frequently identified factors contributing to preventable revisits were related to the choice of postdischarge location and to patient/caregiver understanding of the discharge medication regimen, each occurring in 25.0% of cases. The most frequently cited potentially preventive intervention was "improved self-management plan at discharge," occurring in 65.0% of cases. Five of the 20 preventable revisits (25.0%) had contributing factors that were thought to be directly related to the COVID-19 pandemic.

CONCLUSION: Although only approximately one quarter of 30-day hospital revisits following admission with COVID-19 were potentially preventable, these results highlight opportunities for improvement to reduce revisits going forward.

Deshpande, Bhushan R, Ellen P McCarthy, Yoojin Jung, Timothy S Anderson, and Shoshana J Herzig. (2021) 2021. “Initiation of Long-Acting Opioids Following Hospital Discharge Among Medicare Beneficiaries.”. Journal of Hospital Medicine 16 (12): 724-26. https://doi.org/10.12788/jhm.3721.

Guidelines recommend against initiating long-acting opioids during acute hospitalization, owing to higher risk of overdose and morbidity compared to short-acting opioid initiation. We investigated the incidence of long-acting opioid initiation following hospitalization in a retrospective cohort of Medicare beneficiaries with an acute care hospitalization in 2016 who were ≥65 years old, did not have cancer or hospice care, and had not filled an opioid prescription within the preceding 90 days. Among 258,193 hospitalizations, 47,945 (18.6%) were associated with a claim for a new opioid prescription in the week after hospital discharge: 817 (0.3%) with both short- and long-acting opioids, 125 (0.1%) with long-acting opioids only, and 47,003 (18.2%) with short-acting opioids only. Most long-acting opioid claims occurred in surgical patients (770 out of 942; 81.7%). Compared with beneficiaries prescribed short-acting opioids only, beneficiaries prescribed long-acting opioids were younger, had a higher prevalence of diseases of the musculoskeletal system and connective tissue, and had more known risk factors for opioid-related adverse events, including anxiety disorders, opioid use disorder, prior long-term high-dose opioid use, and benzodiazepine co-prescription. These findings may help target quality-improvement initiatives.

Melanoma continues to be an aggressive and deadly form of skin cancer while therapeutic options are continuously developing in an effort to provide long-term solutions for patients. Immunotherapeutic strategies incorporating antibody-drug conjugates (ADCs) have seen varied levels of success across tumor types and represent a promising approach for melanoma. This review will explore the successes of FDA-approved ADCs to date compared to the ongoing efforts of melanoma-targeting ADCs. The challenges and opportunities for future therapeutic development are also examined to distinguish how ADCs may better impact individuals with malignancies such as melanoma.
