“Our study showed that participating in a collaborative improved the processes of care related to prevention and screening and disease monitoring and treatment for diabetes and asthma, but participating in a collaborative did not improve these processes for hypertension. The study did not show improvements in intermediate outcomes of care. Whether these differences in diseases and outcomes are related to the nature of each targeted condition, aspects of the participating organizations, ease of patient adherence, or the specific collaborative under study is not known. Finally, improvements over time were seen in both intervention and control centers for almost every individual measure. Whether this broad improvement reflects general secular trends or the general quality-improvement environment at community health centers is not known.”
