Implementation of a Protocol to Manage Patients at Risk for Hospitalization Due to an Ambulatory Care Sensitive Condition

Hospitalizations related to ambulatory care sensitive conditions (ACSCs) are potentially avoidable if timely and effective care is provided to the patient. The Agency of Healthcare Research and Quality has identified type 2 diabetes mellitus (T2DM), chronic obstructive pulmonary disease (COPD), hypertension, congestive heart failure (CHF), urinary tract infections (UTIs), asthma, dehydration, bacterial pneumonia, angina without an inhospital procedure, and perforated appendix as ACSCs.^1,2 Identifying patients with ACSCs who are at risk for hospitalization is a potential measure to enhance primary care delivery and reduce preventable hospitalizations

The US Department of Veterans Affairs (VA) Clinical Pharmacy Practice Office implemented a guidance statement describing the role and impact of a clinical pharmacy specialist (CPS) in managing ACSCs.¹ Within the Veterans Health Administration, the CPS may function under a scope of practice within their area of expertise with the ability to prescribe medications, place consults, and order laboratory tests and additional referrals as appropriate. As hospitalizations related to ACSCs are potentially preventable with effective primary care, the CPS can play an essential primary care role to implement interventions targeted at reducing these hospitalizations.

At the William S. Middleton Memorial Veterans Hospital, in Madison, Wisconsin, multiple transitions of care and postdischarge services have been established to capture those patients who are at a high risk of rehospitalization. Studies have been completed regarding implementation of intensive case management programs for high-risk patients.³ Currently though, no standardized process or protocol exists that can identify and optimize primary care for patients with ACSCs who have been hospitalized but are predicted to be at low risk for rehospitalization. Although these patients may not require intensive case management like that of those at high risk, improvements can be made to optimize clinical resources, education, and patient self-monitoring to mitigate risk for hospitalization or rehospitalization. Therefore, this project aimed to evaluate the implementation of offering further referrals and care for patients who have been hospitalized but are considered low risk for hospitalization from ACSCs.
