Professor June Andrews, who led the review into standards of care for older people at the Princess of Wales Hospital and Neath Port Talbot Hospital, commissioned by the Welsh Government, admitted her remit was "quite narrow".
But, she warned: "I often have concerns about the care of older people in hospital everywhere - and I would be wondering whether there would be similar situations happening in other places."
Shadow Health Minister Darren Millar has told AMs that the report on Bridgend and Neath Port Talbot hospitals was horrific and appalling, with echoes of previous reports, such as the Older Persons' Commissioner's Dignity in Care report.
He said people needed to know such failings will never again be tolerated. Mr Millar suggested that financial pressures were partly responsible for what had happened. He said the minister should meet patients and their families and personally apologise to them. Not that an apology would be enough.
Saying sorry isn't going to heal the wounds that this report has exposed.
Mr Millar said he would not ask for heads to roll on this occasion, though he would like to know why the Chief Executive of Abertawe Bro Morgannwg Health Board was chosen to help the Betsi Cadwaladr board with its governance.

Health Minister Mark Drakeford has begun his statement to AMs on the Andrews report by offering his own "unreserved apology" to patients and their families for their treatment at two Abertawe Bro Morgannwg Health Board hospitals.
I am determined that nothing else like this will happen in this health board or elsewhere in Wales.
The minister said he's seeking immediate assurances that failings in basic care, such as the provision of drinking water and help in going to the toilet, are not more widespread. Mr Drakeford announced that there will be a series of unannounced "dignity and essential care" inspections.
Welsh MP Ann Clwyd has warned that today's report into the standards of care at two Welsh hospitals "underlines the urgent need for a radical overhaul of independent regulation and inspection in NHS Wales."
The Cynon Valley MP has worked on complaints procedures within the NHS, after claiming that her husband was "treated like a battery hen" before his death at the University Hospital of Wales in Cardiff.
She has repeatedly said that Healthcare Inspectorate Wales is not fit for purpose, and needs to be replaced with an independent health watchdog.
Today, she said: "these events could not have happened if there was a regulator doing its job. I hope that we shall see an announcement on this as soon as possible."
The Chief Executive of Abertawe Bro Morgannwg University Health Board has rejected calls from campaigners for him to resign, after a damning report found 'unacceptable' levels of care at two of its hospitals.
Paul Roberts said the report authors and the Health Minister recognise that the current leadership at the health board should stay and "see through improvements to care", and that improvements are being made.
First Minister Carwyn Jones has apologised for the treatment of patients uncovered in the Andrews report on the Princess of Wales hospital in Bridgend and Neath Port Talbot hospital.
They [the patients and their families] deserve an apology from the government and I give it now.
It's not possible for the government to be aware of what's happening on every ward of every hospital but the people of Wales will judge the government by its response.
Mr Jones said that the government's response would be spelt out by the Health Minister, Mark Drakeford, who will address AMs later.
The First Minister said there would be no sackings or resignations at Abertawe Bro Morgannwg Health Board, which the report did not recommend. Rather, its recommendations would be accepted without "cherry-picking"
Plaid Cymru health spokesperson Elin Jones says she "wouldn't be surprised" if some of the problems with poor standards of care in the Princess of Wales Hospital and Neath Port Talbot Hospital are "prevalent in other hospitals in Wales."
"The issues that have come out from this report need to be acted on in all hospitals in Wales - and by all health boards."
The Welsh Liberal Democrats have called on the Welsh Government to step in to ensure adequate standards of care in hospitals.
Today's report into the treatment of older people at the Princess of Wales Hospital in Bridgend and Neath Port Talbot Hospital questioned whether the wider organisation of the NHS in Wales "is distracting NHS boards from a proper focus on quality and patient safety."
Kirsty Williams said the Welsh Government was warned about problems two years ago - and now needs to "demonstrate leadership."
The Welsh Conservatives have reiterated their calls for a full inquiry into the levels of care across the NHS in Wales, after today's report into 'unacceptable' levels of care for older people at two hospitals.
Andrew RT Davies has demanded an inquiry similar to that carried out by NHS England Medical Director Sir Bruce Keogh into the Mid Staffordshire NHS Foundation Trust, where hundreds of patients were believed to have died due to poor standards of care over many years.
