RESUMEN
PURPOSE: The reliability and validity of a survey tool that aims to assess and stratify patient care services provided by ambulatory care pharmacists were evaluated. METHODS: The Tool for Assessing Ambulatory Care Pharmacist Practice (TAAPP) was developed by updating the Pharmaceutical Care Clinical Pharmacist Questionnaire. The TAAPP is organized into 2 sections that include 5 domains derived from the Pharmacists' Patient Care Process (PPCP). The first section of the TAAPP gathers the demographic information of the respondents as well as practice site characteristics. The second section aims to assess the activities that ambulatory care pharmacists participate in when providing direct patient care, stratified by PPCP domains. After the TAAPP was created, face validity was established by the study investigators and content validity was confirmed by 5 experts in ambulatory care pharmacy. Lastly, a reliability study was conducted and included pharmacists providing ambulatory care services in outpatient clinics who had been working at their clinical practice site for at least 2 years. The survey was disseminated electronically through a national pharmacy organization listserver. RESULTS: The results of this pilot study support both face and content validity of the TAAPP survey as well as internal consistency reliability of the TAAPP scores when used to evaluate pharmaceutical practices of ambulatory care pharmacists practicing in outpatient clinics throughout the United States. CONCLUSION: Internal consistency reliability testing demonstrated that the TAAPP scores were reliable with a Cronbach's α of >0.7 for each domain and the TAAPP overall.
