Using case management to increase antiinflammatory medication use among a managed care population with asthma

The National Heart, Lung, and Blood Institute (NHLBI) recommends the regular use of antiinflammatory medications to achieve and maintain control of persistent asthma, while recommending that quick-relief beta2-agonist medications should be used to treat acute symptoms and exacerbations. Despite these suggestions, the overuse of short-acting quick-relief medications and underuse of long-acting antiinflammatory medications persists. ConnectiCare, Inc., a regional managed care company, used pharmacy claims data to identify members who had been dispensed a total of three or more beta2-agonist prescriptions for three consecutive months in a 12-month period. These members had also not been prescribed an inhaled corticosteroid, cromolyn sodium, or nedocromil during the same three consecutive months. An intensive case management intervention was developed that included multiple contacts from a nurse case manager to provide education and information about asthma control and the guidelines. Twenty-eight percent (n = 40) were purposively chosen to receive the intensive multiple-contact intervention and the remainder received a standard, single-contact intervention. After adjusting for the effects of age, gender, and pre-intervention medication use, ConnectiCare members who received the intensive intervention were 4.3 times more likely to increase the number of antiinflammatory medication prescriptions dispensed that those who received a standard intervention (p < 0.001). This study suggests that the use of intensive case management for persons identified as inappropriate users of asthma medication may result in medication changes that achieve the long-term control of asthma.
