The Care Quality Commission (CQC) find that basic care for older people in hospitals and care homes still does not meet standards.
The report found that a third of hospitals and care homes failed to meet the standards for nutrition and dignity for older people.
Dignity and Nutrition Inspection is its first dedicated review of privacy, dignity and nutrition in both care homes and hospitals, with five key standards.
The CQC used a section of hospitals, with only 33 of 50 meeting all five key standards, and from the care sector, only 316 of the 500 homes looked at met all the standards.
The Care Quality Commission report, based on a snapshot of services, found about a third failed to meet all the standards for nutrition and dignity.
In general, standards of nutrition seemed to have improved slightly since the last report based on two key standards in 2011, whereas privacy and dignity standards had worsened.
Overall, CQC have said the results as 'disappointing', and give examples of call-bells being left unanswered, bad manners and a lack support at meal times, lack of help in going to the toilet and lack of privacy when getting washed or dressed.
CQC chief executive David Behan said:
It is disappointing people are still not being given enough privacy when receiving personal care and that they are left alone when they call for help.
This is basic care and getting it right can transform a stressful experience for an older person into a supportive and caring one.
Safe, good quality care is not complex or time-consuming. Effective leadership and staff who feel supported make this happen every day.
Dot Gibson, of the National Pensioners Convention, said:
One report after another shows that we still cannot guarantee that when an older person goes into hospital or a care home that they will have their dignity respected.
This is tantamount to institutionalised abuse. Where else in our society would we tolerate such neglect without a huge public outcry?
