Final answer:
The percentage of hospitals that do not track client retention is not specified in the provided data. Key details needed to answer the question are missing, and the provided percentages do not directly relate to the subject of hospital client retention.
Step-by-step explanation:
The question concerning what percentage of respondent hospitals report that they do not track client retention cannot be answered directly with the information provided. None of the statistics given specifically address client retention within hospitals.
To determine such a percentage, one would require data that expressly states the retention tracking practices of these hospitals. It seems the information provided relates to various subjects including business practices, client outcomes in housing programs, general feelings about data privacy, and statistics that could pertain to different entities or services, but there is no clear link to hospital client retention rates.
