Hyperglycaemia increases mortality risk in non-diabetic patients with COVID-19 even more than in diabetic patients.

AIM: Diabetes has been identified as a risk factor for poor outcomes in patients with COVID-19. We examined the association of hyperglycaemia, both in the presence and absence of pre-existing diabetes, with severity and outcomes in COVID-19 patients. METHODS: Data from 74,148 COVID-19-positive inpatients with at least one recorded glucose measurement during their inpatient episode were analysed for presence of pre-existing diabetes diagnosis and any glucose values in the hyperglycaemic range (>180 mg/dl). RESULTS: Among patients with and without a pre-existing diabetes diagnosis on admission, mortality was substantially higher in the presence of high glucose measurements versus all measurements in the normal range (70-180 mg/dl) in both groups (non-diabetics: 21.7% vs. 3.3%; diabetics 14.4% vs. 4.3%). When adjusting for patient age, BMI, severity on admission and oxygen saturation on admission, this increased risk of mortality persisted and varied by diabetes diagnosis. Among patients with a pre-existing diabetes diagnosis, any hyperglycaemic value during the episode was associated with a substantial increase in the odds of mortality (OR: 1.77, 95% CI: 1.52-2.07); among patients without a pre-existing diabetes diagnosis, this risk nearly doubled (OR: 3.07, 95% CI: 2.79-3.37). CONCLUSION: This retrospective analysis identified hyperglycaemia in COVID-19 patients as an independent risk factor for mortality after adjusting for the presence of diabetes and other known risk factors. This indicates that the extent of glucose control could serve as a mechanism for modifying the risk of COVID-19 morality in the inpatient environment.

Successful experience utilizing dexrazoxane treatment for an anthracycline extravasation.

OBJECTIVE: To describe a successful case of dexrazoxane treatment after an extravasation of doxorubicin and share a creative solution for formulary cost management. CASE SUMMARY: A 42-year-old female diagnosed with breast cancer was receiving doxorubicin as adjuvant treatment. The patient recently underwent a right mastectomy for a 3-centimeter grade 3 invasive ductal carcinoma. Three of 20 lymph nodes were positive, and the patient was stage 2B at presentation, with an estrogen receptor/progesterone receptor-positive and HER-2/neu-negative tumor. At an outside hospital, the patient was receiving doxorubicin through an infusion port when extravasation was noted after approximately 15 mL had been infused. She was transferred to Riverside Methodist Hospital and dexrazoxane treatment was initiated within 6 hours after extravasation. She received a full 3-day course of dexrazoxane treatment without complication and was discharged home. Significant delays in chemotherapy administration were avoided, and the patient successfully completed her planned chemotherapy course. DISCUSSION: Dexrazoxane has the potential to minimize tissue damage and treatment delays after an anthracycline extravasation. Although dexrazoxane is commercially marketed for 2 separate treatment indications, Totect is the Food and Drug Administration-approved product for anthracycline extravasations. Facilities administering anthracyclines should proactively resolve how to obtain, process, prepare, and administer this antidote to a patient within 6 hours of an extravasation event. Developing a preprinted chemotherapy extravasation order may facilitate the incorporation of the most recent Oncology Nursing Society guidelines to utilize dexrazoxane for an anthracycline extravasation. Cost sharing with other institutions may offer a creative solution to lessen the financial impact of stocking dexrazoxane therapy. CONCLUSIONS: Ensuring expedient treatment and accessibility to dexrazoxane therapy after an anthracycline extravasation is critical to the success of the treatment. All facilities utilizing anthracycline chemotherapy should purchase dexrazoxane or secure agreements with other facilities to guarantee the administration of this medication should extravasation occur.

Usefulness of herbal and dietary supplement references.

OBJECTIVE: To describe the usefulness of some of the most common tertiary references that healthcare professionals employ to answer requests about herbal and dietary supplements. METHODS: All requests for information on herbal and dietary supplements received by the drug information service between April and September 2000 were evaluated. Each question was independently reviewed by 4 clinicians using a 4-point scale; 14 references were searched for appropriate answers. The percent of responses for each of the possible scores for each reference overall and by category of question was reported to determine the most helpful references for answering the broadest range of questions. RESULTS: Fifty questions regarding herbal and dietary supplements were analyzed. The electronic databases (Natural Medicine Comprehensive Database, Micromedex) and the Internet site (The Natural Pharmacist) were determined to be overall the most helpful references for providing information on herbal and dietary supplements. The Natural Therapeutics Pocket Guide was the most helpful book reference. CONCLUSIONS: These results will facilitate the retrieval of useful information on herbal and dietary supplements and enable healthcare professionals to determine appropriate allocation of resources as they build a drug information library for handling requests about these products.

Relationship between asthma drug therapy patterns and healthcare utilization.

BACKGROUND AND OBJECTIVE: Asthma drug therapy problems contribute significantly to preventable hospitalizations and increased healthcare use in asthmatics. Since asthma patients often require >1 medication for control of symptoms, concurrent asthma drug therapies may be important in predicting excessive healthcare utilization. The purpose of this study was to link inappropriate asthma drug therapy patterns and selected patient demographics to healthcare utilization. METHODS: This study was a retrospective, cross-sectional analysis of Ohio Medicaid medical, institutional, and prescription claims. We included ambulatory patients aged 15-65 years who had > or =2 claims for asthma (493.x) and who were continuously enrolled in the Medicaid fee-for-service program for the 12-month period from April 1998 through March 1999. We examined age, race, gender, metropolitan residence, presence of gastroesophageal reflux disease, and the usage patterns of inhaled corticosteroids, short-acting beta(2)-agonists, long-acting beta(2)-agonists, theophylline, and leukotriene receptor modifiers to identify asthma drug therapy problems based on national guidelines. The primary outcomes included the number of asthma-related hospitalizations, asthma-related emergency department visits, and oral steroid bursts. RESULTS: Among 10 959 asthma patients, only 46.8% of the study patients received >1 puff of inhaled corticosteroid per day. Forty-four percent of the patients received >3 puffs of short-acting beta(2)-agonists per day. The most common outcome was an oral steroid burst (46.5%). Patients on high doses of short-acting beta(2)-agonists had the greatest odds of receiving an oral steroid burst and were most likely to be hospitalized. African Americans were more likely to incur a hospitalization or emergency department visit. Women had greater odds of any undesirable asthma outcome. Higher use of short-acting beta(2)-agonists led to higher odds of receiving a steroid burst or being hospitalized. Leukotriene receptor modifier use was related to higher levels of all outcomes. CONCLUSIONS: A large percentage of Ohio Medicaid patients were not receiving asthma medications in compliance with the National Heart, Lung, and Blood Institute guidelines. Despite nearly a decade of national efforts, asthma drug therapy patterns still have substantial room for improvement and continue to be associated with excess healthcare utilization.
