The report has not been made public but has been seen by the BBC.
It found that untrained staff were carrying out risky restraints on patients and that the number of restraints was high.
It said face-down, and particularly face down in a prone position, are the highest tariff interventions of physical restraint, and the most dangerous techniques to deploy.
The report looked at a sample of 40 cases and found more than half were patients being restrained face down on the floor for longer than 30 minutes.
The longest restraint was one hour and 45 minutes.
“That is completely against all guidelines,” Prof Tyrer said.
“You may have to do things for five minutes or up to 10 minutes but to go beyond 40 minutes there is something badly wrong in the organisation of a unit if that is allowed to continue.”
Carseview is a hospital to care for patients with mental illness from depression and anxiety to schizophrenia and psychosis.
In July last year, BBC Scotland broadcast allegations by patients of bullying by staff, illegal drug-taking and being pinned to the floor unnecessarily.
Experts called it abusive and said the unit should be closed down.
NHS Tayside responded by commissioning an internal report into Carseview to go alongside independent reports into mental health in Tayside.
The internal report says a whistleblower has come forward and accused Carseview of “very serious concerns over leadership, safety and malpractice”.
It came up with 11 recommended actions including urgent action on staff training and critical action on illegal drugs on the ward.
It said the restraint policy should emphasise the safety of patients as well as staff and that the culture of the unit should be “based around the caring and compassionate leadership approach”.
NHS Tayside said the recommendations covering patient care and culture were “now being progressed”.
Prof Peter Stonebridge, acting medical director for NHS Tayside, said a “steering group has been established” to focus on restrictive care practices, including the reduction of face-down restraint.
Joy Duxbury, professor of mental health at Manchester Metropolitan University, told BBC Scotland: “I think this is a terribly toxic environment.
“The figures on physical restraint are exceptionally worrying.
“These are very vulnerable clients who are being restrained, in my view, unnecessarily and by far too many staff in too many situations.
“For me, given what we know about psychological and physical trauma of the use of restraint in such setting, this is of significant concern.”
Marnie Stirling, who had two stays in Carseview with anxiety and depression, spoke to the BBC documentary last year.
Reacting to the report, she said: “If you think about mental health, it’s supposed to be about recovery. This isn’t recovery, it’s further punishment for people.”
David Fong spent a month in the unit after experiencing psychosis in 2013.
He claimed staff used restraint violently and repeatedly during his time there.
His mother Lorraine said: “This is a total and utter disgrace that this has gone on for seven years and maybe longer.”
David told BBC Scotland that staff were quick to see frustration and anger arising from detainment as aggression.
“Staff are too keen to initiate restraint and offer little or no de-escalation when no actual aggression has been displayed by the patient,” he said.
“I ask how many of these restraints were actually needed and if some are instigated by staff rather than patients?
“I personally was physically assaulted with the application of intense pain through twisting of arms, wrists and fingers or a member of staff’s knee being dug into my back, had my face rubbed into the floor causing loss of skin from my face, and had verbal abuse screamed at me during restraint.
“I also could not have been the only patient that these tactics were being used upon.”
A separate report looking at the patient experiences came up with separate 23 recommendations in December.
It is feeding into an independent inquiry, which was announced in the Scottish Parliament last year, and is still ongoing.
A Fife director is hoping to release a new film with a focus on coping with depression over the festive season in time for Christmas 2019.
‘Cold’, which has been written and produced by Kirkcaldy film maker Gavin Hugh, is being filmed in locations across Kirkcaldy, Stirling, Edinburgh and Aviemore, with two days of filming already in the can.
It is a huge personal undertaking for Gavin, who has previously worked for STV and Sky News and has been running his own Kirkcaldy-based video production business, MidgieBite Media, since late 2017 while also working part time at the Scottish Parliament as an assistant to Dundee City East MSP Shona Robison.
However, with the production funded through goodwill and his own pocket so far, Gavin and his team plans to launch a crowdfunding campaign early this year to help finish the film and release it in winter 2019.
“For a lot of us, Christmas is a happy time of year where we can celebrate and put all of our troubles to one side but for people suffering with depression it can be incredibly difficult to do that,” Gavin explained.
“We focus on how the pressure of trying to take part in the festivities and putting on a brave face just isn’t something that can be easily switched on and off in time with the days on a calendar.
“Taking care of your own mental health is easy to overlook. I’ve had my own issues with anxiety over the years, and some of the people that I’m closest to in my life have suffered from depression.
“Mental health issues can be challenging not just for the individual but for the people around them who are trying to offer support.
“As this film is drawing on a lot of personal experiences, it’s really important for me that our film gives an honest portrayal of these issues.
“While there’s an increasing awareness of mental health issues in mainstream society, we’re really hoping that the film can help encourage people to still be mindful of them at this time of year.”
Gavin has been involved in a lot of local film projects over the years, particularly with horror filmmakers Hex Media, and has recently been working closely with Robbie Davidson on his upcoming World War Two epic ‘Dick Dynamite’.
Most of the primary cast for Cold are Fifers, including Andrew Gourlay, Hana Mackenzie, Craig Seath and Iain Leslie, as are most of the technical crew.
Lead actress Rowan Birkett, a friend of Gavin’s from student days at Stirling University, has been travelling up from Ambleside in England to take part, while Dundee is also represented in Grant R Keelan, a city-based photographer who acts in the film as well as working in the technical team.
“It’s genuinely been great to work with so many talented local artists,” he added.
More details about the crowdfunding campaign will be announced in due course, and the plan is to hold a premiere of the new film in Kirkcaldy later in the year.
Suicide rates in Dundee are higher than any other city council area in Scotland, according to a new report.
The Scottish Suicide Information Database also shows that men accounted for three-quarters of suicides across Tayside in the last seven years.
According to the report, there were 164 deaths caused by suicide in Dundee with an average of 16.7 per 100,000 population between 2011 and 2017.
Angus along with Perth and Kinross Councils recorded 98 and 126 suicides respectively.
For Tayside as a whole, 388 suicides were recorded with an average per 100,000 population of 14.1.
Men were more likely to take their own lives, with the rates across Scotland highest among those aged 35-54 and in deprived areas.
Nearly three-quarters of those who died had contact with healthcare services in the year before their death.
An inquiry is currently under way into NHS Tayside’s mental health services after a number of concerns surrounding the Carseview Centre.
Phil Welsh, whose 28-year-old son Lee took his own life last year, said the latest statistics were “damning”.
He said: “It’s clear that there’s a situation here that isn’t working.
“I think the fact there is an inquiry shows there’s something amiss.
“Mental health is a discussion point now but it’s all well talking, we need support for people afterwards and that is why we badly need a crisis centre.”
A spokeswoman from NHS Health Scotland said: “National suicide prevention programmes need to incorporate a comprehensive public health approach which seeks to reduce stigma, improve mental wellbeing in the whole population and address the underlying causes of poor mental health.”
The Scottish government has ordered a review of mental health services for young people in custody.
It follows recent deaths at Polmont Young Offenders Institution.
Sixteen-year-old William Lindsay died while on remand there in October and 21-year-old Katie Allan took her life in June while detained for a drink-driving offence.
Justice Secretary Humza Yousaf said the review would involve a mental health expert and HM Inspectorate of Prisons.
The review is expected to report back early next year.
It will look at mental health provision for young people entering custody, including background information ahead of their admission, reception arrangements, and ongoing support and supervision while in custody.
Mr Yousaf announced the review in a letter to the Scottish Parliament’s justice and health committees.
Health Secretary Jeane Freeman has also confirmed that NHS Forth Valley has already engaged with the Scottish Prison Service to assess and increase provision for people living at Polmont.
In his letter, Mr Yousaf said that although fatal accident inquiries would be undertaken into the deaths of William Lindsay (also known as William Brown) and Katie Allan “I have reflected on some of the more immediate questions raised particularly around the provision of mental health support and services for young people in custody”.
He said the review would look at relevant operational policies, practice and training and where practical, would also look at comparisons between the support and arrangements in place in secure care accommodation and HMP&YOI Polmont.
He added: “As with current formal inspection and independent monitoring arrangements for prisons, the review will include direct engagement with young people in custody about their experiences.
“The review will not consider the specific circumstances of recent cases which are the subject of current or future mandatory fatal accident inquiries.
“We are also aware of issues being raised about the information that is available about a young person’s history before decisions are taken that can lead to them being sent to custody or secure care. Separate consideration is being given to how best to look at these issues.”
Ms Allan, a 21-year-old geography student at Glasgow University, was convicted in March of a drink-driving offence which saw her injure a pedestrian and she was sentenced to 16 months in jail.
Stuart and Linda Allan said their daughter was bullied in Polmont YOI near Falkirk and lost more than 80% of her hair due to the state of her mental health. She died there in July.
They had called for a review of the Scottish prison system.
Mr Lindsay, who was also known as William Brown, was one of four deaths in the space of two days at Scottish jails last month.
An entry on the Scottish Prison Service (SPS) website states he was remanded at Glasgow Sheriff Court on Thursday 4 October.
He died on Sunday 7 October.
Lawyer Aamer Anwar, representing the families of Ms Allan and Mr Brown, said they cautiously welcomed the announcement of a review.
“The deaths of Katie and William were never inevitable, the system and the Scottish Prison Service (SPS) failed them,” he said.
“The families of Katie Allan and William Lindsay expect and demand a lot more to happen in the days and weeks ahead.
“Today is a good start, but the families hold Polmont responsible for suicides which took place, ultimately they failed in their duty of care.
“If this review is independent then the families wait to see the proof of that as they must be fearless in the questions they ask.”
Bosses at the health board aim to get rid of 1,300 posts to plug the hole in its finances, official papers revealed.
They say they can do that over several years through “natural staff turnover”, but it is feared cuts to backroom staffing will have an impact on patients.
The decision to shrink the workforce comes as the board benefits from having at least £62 million of debt written off by the Scottish Government.
The plans are revealed in an assurance report to the board from September.
It said there was an “acceptance that staff levels need to reduce by 10%”.
Gillian Murray, who has been campaigning for better mental health services after failings in the care of her late uncle, said the decision shows that “balancing the books obviously means more to them than saving lives”.
“People in Dundee are dying because NHS Tayside is a shambles and to cut the workforce is another slap in the face for all of us,” she added.
Murdo Fraser, the Conservative MSP in Perthshire, said: “Local people will be wondering what impact these massive reductions in staff will have on their already pressured services.”
Annie Ingram, NHS Tayside director of workforce, said no one will lose their job but said spending on the workforce is higher than health boards of a similar size.
She added: “We are carrying out a review of staff numbers, grades and skills, which is being carried out in partnership with our staff and our trades unions, to ensure we have a safe, affordable and sustainable workforce.”
He has called for “all those politicians who claim to care about justice or young people” to “consider their shameful silence on this issue”.
Responding to the latest case, a Scottish government spokesman said: “Our thoughts are with the family and friends of this young man.
“Investigations have begun ahead of the Fatal Accident Inquiry and it would therefore be inappropriate to comment on the specifics of this individual case.
“We recognise, however, that many young people entering the criminal justice system have complex needs and we work with agencies to ensure appropriate support is available when needed.”
A Crown Office spokesman said: “The investigation into the death of William Brown (or Lindsay) is ongoing and is under the direction of Scottish Fatalities Investigation Unit (SFIU).
“There will be a mandatory Fatal Accident Inquiry in due course once investigations are complete.
“The family will be kept updated in relation to any significant developments.”
An SPS spokesman said: “Every death in custody is subject to a DIPLAR (Death in Prison Learning and Audit Review), which we will conduct along with partner agencies, and that process would feed into the FAI.”
