From the Guidelines
The most appropriate monitoring parameter for a 68-year-old male with severe community-acquired pneumonia receiving hydrocortisone 200 mg IV continuously is blood glucose levels. Based on the findings from the Community-Acquired Pneumonia: Evaluation of Corticosteroids (CAPE COD) study, patients on hydrocortisone required significantly higher doses of insulin compared to those on placebo, indicating a higher risk for hyperglycemia during corticosteroid therapy 1. Regular blood glucose monitoring should be implemented, with capillary blood glucose checks at least four times daily (before meals and at bedtime) while the patient remains on hydrocortisone. If hyperglycemia develops, sliding scale insulin or basal-bolus insulin therapy may be necessary. This monitoring is crucial because corticosteroids increase hepatic glucose production and decrease peripheral glucose utilization, leading to insulin resistance. Uncontrolled hyperglycemia in critically ill patients can worsen outcomes by increasing infection risk, impairing wound healing, and prolonging hospital stays. The healthcare team should also be aware that blood glucose levels typically normalize after discontinuation of corticosteroid therapy, so insulin requirements should be reassessed when hydrocortisone is tapered or discontinued.
Some studies suggest that corticosteroids may increase the risk of secondary infections and gastrointestinal bleeding, but the most recent and highest quality study, which is the 2019 guideline from the American Thoracic Society and Infectious Diseases Society of America, does not provide strong evidence for routine monitoring of these parameters in patients with severe CAP receiving corticosteroids 1. However, it is essential to be aware of these potential complications and monitor the patient closely for any signs of infection or bleeding.
In terms of the duration and dosing of corticosteroid therapy, the Society of Critical Care Medicine and European Society of Intensive Care Medicine suggest using corticosteroids for 5-7 days at a daily dose < 400 mg IV hydrocortisone or equivalent in hospitalized patients with CAP 1. However, the decision to initiate and continue corticosteroid therapy should be individualized based on the patient's clinical response and risk factors for adverse events.
Key points to consider when monitoring a patient on hydrocortisone for severe CAP include:
- Regular blood glucose monitoring
- Monitoring for signs of secondary infection
- Monitoring for signs of gastrointestinal bleeding
- Individualized decision-making regarding the duration and dosing of corticosteroid therapy
- Awareness of the potential for insulin resistance and hyperglycemia
- Reassessment of insulin requirements when hydrocortisone is tapered or discontinued.
From the Research
Monitoring Parameters for Hydrocortisone Therapy
The patient in question is receiving hydrocortisone as part of their treatment for severe community-acquired pneumonia (CAP). Based on the findings from the Community-Acquired Pneumonia: Evaluation of Corticosteroids (CAPE COD) study 2, the following monitoring parameters are relevant:
- Hyperglycemia: Patients on hydrocortisone required significantly higher doses of insulin compared to those on placebo, indicating a higher risk of hyperglycemia while on hydrocortisone therapy.
Key Considerations
Some key points to consider when monitoring this patient include:
- The CAPE COD study found no significant difference in the frequencies of hospital-acquired infections and gastrointestinal bleeding between the hydrocortisone and placebo groups 2.
- Other studies have also found that corticosteroids can increase the risk of hyperglycemia in patients with CAP 3, 4, 5, 6.
- The use of corticosteroids in CAP may reduce mortality, the need for mechanical ventilation, and ICU admission, particularly in more severe cases 6.
- It is essential to closely monitor the patient's blood glucose levels and adjust their insulin therapy as needed to prevent hyperglycemia.
