We first began our search for quality measures of PTSD care similarly, by defining search terms (see Table II.1). We then searched the three most widely used sources of quality measures: the National Quality Measure Clearinghouse (NQMC), the NQF, and the online inventory maintained by the Center for Quality Assessment in Mental Health (CQAIMH). Additionally, we searched the Published International Literature on Traumatic Stress (PILOTS) database, which includes a large inventory of measures that are primarily used in research, and the HHS Substance Abuse and Mental Health Services Administration's (SAMHSA's) National Outcomes Measures. Our search for quality measures included measures related to PTSD care as well as ones related to physical or behavioral health conditions that commonly co-occur with PTSD (see Appendix A). We again summarized the information in an Excel spreadsheet that included information on the measure developers, specifications and data sources, NQF endorsement status, and level of evidence to support the measure.
