IMPACT - Integrative Medicine PrimAry Care Trial
Study Details
Study Description
Brief Summary
This study is Phase II of a project by the University of Arizona Center for Integrative Medicine (AzCIM). Collaborating with AzCIM is the Health Outcomes and Pharmacoeconomics (HOPE) Center and the RAND Corporation, Inc. Phase II is a prospective evaluation of the clinical and cost effectiveness (outcomes) of an integrative medicine professional practice model for adult primary care delivery (the University of Arizona Integrative Health Center - UAIHC in Phoenix, AZ). Data will be gathered from eligible and consenting members of UAIHC. In addition, a fidelity evaluation will assess whether the practice model was implemented as planned.
The specific aims are to: 1) Recruit, consent, and enroll a sample of eligible patient and staff participants from UAIHC; 2) Conduct outcome evaluation of UAIHC care using patient data from medical records abstractions, self-report assessments, clinic administrative and service utilization/encounter data, and health insurance claims data; and, 3) Conduct fidelity evaluation of the implementation of the UAIHC model as described in its business plan using patient- and staff-reported fidelity assessments, random chart audits, and abstracted clinic administrative data.
Participants. 1) Participants from the clinic patient population for whom clinical and cost outcomes will be tracked (n=500); 2) Clinic patients from whom fidelity data will be collected (n=180); and, 3) Clinic personnel from whom fidelity data will also be collected (n=14).
Data Collection. For outcomes evaluation, data will be collected at baseline (initial clinic visit), and at 3-, 6-, and 12-month follow up periods. Sources include clinical symptoms and biomarkers from medical records abstractions; patient reported outcomes and satisfaction questionnaires; clinic service encounter logs; and, cost data from health insurance claims information and clinic financial data. For fidelity evaluation, data will be collected monthly for 6 months after study start, quarterly for the next 6 months, and semi-annually from then on. Patient data for fidelity will be gathered on a single randomized day of the week using a self-administered patient feedback questionnaire. For personnel, fidelity data will be collected at the same intervals using a self-administered provider perceptions questionnaire of inter-professional team and integrative medical care. Data from audits of randomly selected patient charts and administrative records will also be used.

Outcome Measures
Primary Outcome Measures
- Total healthcare costs from the payer's perspective-total paid costs according to claims data. [12 months of paid costs pre and post beginning membership at UAIHC]
Secondary Outcome Measures
- 1. Self-report instruments [Baseline, 3-, 6-, and 12-months]
Composite: Short Form -12 (Ware, 1996) WHO-5 Well-being Index (Bech, 2003) Perceived Stress Scale (Cohen 1983). Work Productivity and Activity Impairment (Reilly, 1993). Patient Activation Measure (Hibbard, 2004). Diet quality. Behavioral Risk Factor Surveillance System Fruits/Vegetables (CDC, 2012). Physical Activity. Behavioral Risk Factor Surveillance System Physical Activity (CDC, 2012). Stress burden (Littman, 2006). Depression. PHQ-2 (Kroenke, 2003). Anxiety Disorder. GAD-2 (Kroenke, 2007). Pittsburgh Sleep Quality Index (Buysse, 1989). Fatigue visual analogue scale. Fatigue Severity Scale (Krupp, 1989). Pain visual analogue scale. If diagnosed: Fibromyalgia Impact Questionnaire-R (Williams & Arnold, 2011); Roland-Morris Disability Questionnaire (Roland & Morris, 1983); PHQ 9 (Kroenke et al 2002); GAD 7 (Spitzer et al, 2006). Demographics (Baseline). Expectations for care (Baseline). Patient satisfaction. 2-items from the CAHPS (AHRQ, 2012).
- Clinical indicators and biomarkers [3-, 6-, and 12-months]
Composite: Complete metabolic panel, hypoglycemic medication, full lipid panel (TC, HDL, fasting triglycerides), lipid medication, TSH/T4, HbA1c, systolic and diastolic blood pressure, hypertension medication, BMI (height & weight), waist circumference, body fat composition, smoking status, cardiovascular disease risk (general and events), metabolic syndrome diagnosis.
- Service Utilization Data and Health Insurance Claims Data [3-, 6-, and 12-months; biennially]
Other Outcome Measures
- Patient Experiences (Fidelity) [Monthly for the first 6 mos., then each 3 months for the rest of the first year, then every 6 months.]
Composite: Dimensions assessed: access to care, whole person care, promotion of self-care and wellness, practitioner communication style, shared decision-making, trust in the practitioner, perceived practitioner empathy, perceived health partnership, and demographic information (CAHPS - AHRQ, 2012; ACES - Safran et al, 1998); CARE - Mercer, et al, 2004).
- Provider Experiences (Fidelity) [Monthly for the first 6 months, then each 3 months for the rest of the first year, then every 6 months]
Composite: Team Climate Inventory Short Version (TCI - Anderson & West, 1995; Loo & Loewen, 2002). Additional items were derived from a study of integrative medicine team practice (Gaboury, et al, 2010). Items on integrative team collaboration, integrative treatment planning, personal development, and clinical skills development were developed for the study.
- Medical records chart audit (Fidelity) [Monthly for the first 6 months, then each Monthly first 6 months then q. 3 months for the rest of the first year, then every 6 months]
Composite: Evidence of principles and best practices of integrative medicine: Whole person assessment and treatment; patient-practitioner health partnership; use of both conventional and CAM methods; health promotion and prevention interventions; use of natural and least invasive treatments where possible (support for body's innate healing capacity); patient personal care support team/team-based approach; extended visits/spending adequate time with patients; access to comprehensive, integrated, care.
