A realist review of the home care literature and its blind spots.

We conclude by providing advice for supporting the design and implementation of stronger home care delivery systems. Our analysis suggests that doing so implies a series of sequential steps: identify what system-level goals the model should achieve and which populations it should serve; identify what type of services are likely to achieve those goals in order to establish a basket of services; and finally, identify the best ways and specific means to effectively and efficiently provide those services. Those same steps can also support ex-post evaluations of existing home care systems.
