A Cost-Effectiveness Analysis of Corticosteroid Injections and Open Surgical Release for Trigger Finger.

PURPOSE: To evaluate the cost-effectiveness of corticosteroid injection(s) versus open surgical release for the treatment of trigger finger. METHODS: Using a US health care payer perspective, we created a decision tree model to estimate the costs and outcomes associated with 4 treatment strategies for trigger finger: offering up to 3 steroid injections before to surgery or immediate open surgical release. Costs were obtained from a large administrative claims database. We calculated expected quality-adjusted life-years for each treatment strategy, which were compared using incremental cost-effectiveness ratios. Separate analyses were performed for commercially insured and Medicare Advantage patients. We performed a probabilistic sensitivity analysis using 10,000 second-order Monte Carlo simulations that simultaneously sampled from the uncertainty distributions of all model inputs. RESULTS: Offering 3 steroid injections before surgery was the optimal strategy for both commercially insured and Medicare Advantage patients. The probabilistic sensitivity analysis showed that this strategy was cost-effective 67% and 59% of the time for commercially insured and Medicare Advantage patients, respectively. Our results were sensitive to the probability of injection site fat necrosis, success rate of steroid injections, time to symptom relief after a steroid injection, and cost of treatment. Immediate surgical release became cost-effective when the cost of surgery was below $902 or $853 for commercially insured and Medicare Advantage patients, respectively. CONCLUSIONS: Multiple treatment strategies exist for treating trigger finger, and our cost-effectiveness analysis helps define the relative value of different approaches. From a health care payer perspective, offering 3 steroid injections before surgery is a cost-effective strategy. TYPE OF STUDY/LEVEL OF EVIDENCE: Economic and Decision Analyses II.

The Increased Clinical and Economic Burden of Hyperkalemia in Medicare Patients Admitted to Long-Term Care Settings.

INTRODUCTION: Older patients are at increased risk for hyperkalemia (HK). This study describes the prevalence, recurrence, and clinical and economic burden of HK in Medicare patients admitted to a long-term care (LTC) setting. METHODS: Retrospective cohort study using 100% Medicare Fee-for-Service (FFS) claims identified patients aged ≥ 65 years with index admission between 2017 and 2019 to a LTC setting (skilled nursing, home health, inpatient rehabilitation, or long-term acute care). Beneficiaries were required to have 12 months continuous medical and pharmacy coverage prior to index LTC admission and ≥ 30 days after LTC discharge (follow-up). Patient characteristics, healthcare resource utilization, and costs were assessed. HK was defined as ICD-10 diagnosis code E87.5 in any claim position or Medicare Part D fill for oral potassium binder. RESULTS: Of 4,562,231 patients with a LTC stay, the prevalence of HK was 14.7% over the full study period (pre-index, index stay, and follow-up). Excluding those with HK only during the follow-up period resulted in 4,081,103 patients. Of these, 290,567 (7.1%) had HK and 3,790,536 (92.9%) did not have HK during or within 14 days prior to index LTC stay. The HK recurrence rate during index stay and follow-up was 48.3%. Unmatched HK versus non-HK patients were more often male (43.0% vs. 35.4%), Black (13.5% vs. 8.0%), dual eligible for Medicaid (34.2% vs. 25.0%), with higher mean Charlson Comorbidity Index scores (6.2 vs. 3.9) (all p < 0.0001). After propensity matching, HK patients were 2.2 times more likely to be hospitalized, with higher mortality (30.8% vs. 21.5%) and higher total healthcare costs during both index stay (US$26,520 vs. $18,021; p < 0.0011) and follow-up ($57,948 vs. $41,744 (p < 0.0011) versus matched non-HK patients. CONCLUSION: Prevalence and recurrence of HK was high among LTC patients, and HK was associated with significantly greater clinical and economic burden during and post-LTC.

Hyperkalemia is a serious medical condition commonly occurring in nursing home residents. It is characterized by abnormally high blood levels of potassium that if untreated can be life-threatening. High levels of potassium can be the result of kidney disease and inability to remove potassium from the bloodstream; eating foods high in potassium; and/or taking medications that interfere with the kidney's ability to remove potassium from the bloodstream. Older patients who have chronic kidney disease, heart failure, diabetes, and high blood pressure are at particularly high risk for hyperkalemia. Management is difficult as it requires reducing intake of foods high in potassium, adjusting medications that cause hyperkalemia, and potentially treating with oral potassium binders to reduce potassium blood levels. This study focused on the clinical outcomes, healthcare services use, and costs incurred by Medicare beneficiaries 65 years and older admitted to long-term care, where the occurrence of hyperkalemia is often high yet unrecognized. Patients with a diagnosis of hyperkalemia immediately before and during admission to long-term care or after discharge had an increased rate of death compared with patients without a hyperkalemia diagnosis. Hyperkalemia patients also had more hospitalizations and visits to the Emergency Department and outpatient facilities, resulting in higher total medical costs. Total costs for hyperkalemia patients were highest for those with chronic kidney disease, heart failure, and diabetes.
