Poor relationships between GPs and hospitals also meant patients staying in longer than necessary, it added, BBC reported.
The Healthcare Inspectorate Wales (HIW) report said ‘significant attention’ was needed at hospitals.
A Welsh government spokesman said systems were being rolled out to improve the situation.
But HIW called for more discussions between professionals and families about how and when discharge will take place, and said poor IT systems were stopping GPs getting enough relevant information.
Without a national approach for addressing so-called ‘bed blocking’, health board policies were ‘fragmented’, according to HIW's chief executive Dr. Kate Chamberlain.
The issue was highlighted last year when a patient described as ‘fit for discharge’ waited four years at a hospital in the Hywel Dda health board area.
Health Secretary Vaughan Gething blamed difficulty in putting together a package to meet the patient's ‘complex needs’, while the Welsh government said delayed transfer of care figures were at the lowest level for 12 years.
But the HIW report said the way a patient was discharged from hospital was ‘critical to the effectiveness of their ongoing care in the community’.
It made 13 recommendations and observations, including:
● The process is more efficient where ward-based pharmacy staff are used.
● Using an electronic discharge system was found to give better and quicker information to GPs.
● Insufficient engagement with patients and families on how and when discharge will occur.
● Calls for greater clarity of the professionals involved in the process, with stronger relationships between GPs and hospitals
While describing the quality and timeliness of discharge across Wales as ‘variable’, the report said progress was being made.
But it said professionals needed to take ‘greater responsibility’, adding: "We found that all health boards had appropriate policies in relation to discharge.
"However, there appears to be a lack of awareness and understanding of these processes from staff on some wards and this lack of clarity, combined with poor IT infrastructure and a failure amongst professionals to take responsibility for effective communication, can put patients at risk."
Dr. Chamberlain said: "Addressing this requires each professional involved in a patient's care to take responsibility for their part in effective discharge."
'Matter of urgency'
A Welsh government spokesman said a number of IT methods were either being implemented or reviewed.
"The Medicines Transcribing and e-Discharge system is currently being rolled out to all hospitals in Wales, providing GPs with immediate access to high quality electronic discharge information," he said.
"We are also increasingly sharing this information with patients' nominated community pharmacists to ensure that any changes to medicines made in hospital are continued in the community."
He added that the systems used by NHS Wales were being reviewed.
The Royal College of Nursing in Wales said it particularly identified with the needs to strengthen relationships between hospitals and those in community care roles.
"Discharge liaison nurses would be ideally placed to do this," said associate director Helen Whyley.
"The NHS needs to increase their numbers and develop their roles if it wants to deliver the Welsh government's prudent healthcare principles in this area."
Whyley called for improved electronic discharge planning ‘as a matter of urgency’, adding: "Nurses understand how patients need to be at the center of their care and by ensuring adequate numbers of nurses, research shows outcomes are improved, including discharge planning."
