This comes as a survey found that one in five people who have used the health service in the last year have received a meeting letter after the date it was to be held.
These types of errors are “disappointing” and can seriously affect patients’ safety, experts said.
Patient groups have also warned the government’s goal of reducing NHS waiting lists “will fail” if the health service “cannot communicate with people effectively.”
A report from the HealthWatch England King Fund and the national voices is called waste of money, time and staff. “
The survey includes a poll of 1888 adults in England conducted by IPSOS.
Of the 1622 people who stated that they had used NHS services in the previous 12 months – either for themselves or for someone they care for – more than six per 10 (64%) were the explicit communication problems.
Almost one -third (32%) said they had to pursue results after a test, scan or X -ray, until the same proportion was maintained updated for how long they would have to wait for treatment.
Nearly a quarter (23%) said they did not know who to contact while waiting for care, while one of five (20%) said they had received a meeting letter after it was to be held.
Julia Cream, an associate of the King’s Fund and the co -author of the report, said: “Today’s results are NHS daily dysfunction, which is not too often meets the needs of people and emphasizes the deep inequalities that people experience when they try to have access And to engage in health services.
“Behind these numbers are stories of people who are worried about their health and struggling to cross the NHS front door.
“The government is trying to download the waiting lists and improve access, but these efforts will fail if NHS cannot communicate effectively with people about when their appointment is or with whom they should contact.”
The study also found that people who have experienced at least one administrative problem, more than four in 10 (42%), said there would be less likely to seek care in the future.

Almost half (47%) said they left them to think that the quality of care NHS provides is bad.
Louise Ansari, CEO of Healthwatch England, added: “We heard countless stories of people whose NHS letters arrived after the day of the meeting or were sent to the wrong address while some were lost their referrals in the system.
“Administrative errors are disappointing and can have serious consequences for the patient’s safety.
“If people miss their tests or scanning, they will encounter a longer waiting for their care, putting their health at risk.”
D -Azari also warned the bad administrator “puts the weight of the patient”, which often needs to “arrange the problems that NHS systems create”.
She added: “This puts a particularly heavy load for people with disabilities and those who have sensory damage.”
Jacob Lan, CEO of National Voices, said: “The administrator plays a decisive role in how patients are experiencing healthcare, but our study shows that many people find themselves in an administrator cycle caught by emails without reports and cannot have access to the person or to the person or answers they need.
“It goes beyond the inconvenience, often rising the quality of people’s care.”
John Sparks, CEO of the Charity Organization for Damage to Mencap, said: “For people with impairment of training, these barriers to healthcare are part of the picture, where they die up to 23 years earlier than the total population, as many of their mortals Cases are avoided.
“Delaying access to care and treatment are a key engine of these shocking inequalities.
“A bad administrator is not just an inconvenience that actively deepens inequalities in health.”
Responding to the report, Dr. Victoria Tsortzu-Brown, Vice-Chairman of the Royal College of GPs, said the administrators ‘mistakes were adding family doctors’ bureaucratic workloads.
“GPS becomes as disappointed as our patients when their care is disturbed by administrative problems and that they fail,” she added.
“GPS and the members of our team often participate in the pursuit of test results, missing letters and meetings with our patients, adding to our bureaucratic workload at a time when the need for our care is rocket and we have a severe GPS deficiency.”
A NHS spokesman said: “This timely report emphasizes another consequence of the long -term capital capital that NHS is facing, with too many organizations still struggling with outdated technology and data systems to support the effective administration of patients. We started to deal with this through investment in the digitalization of the front line and the NHS application, but we know that we need to go much further to make sure that patients have the necessary information in the right place and on time.
“We have identified some of our plans to make additional improvements to the NHS Election Reform Plan and we will work with the government to build NHS, suitable for the future through the 10 -year health plan.”
And the Ministry of Health and Social Care Spokesman said: “We upgrade the NHS application so that patients can book and rearrange meetings, choose which hospital to treat, receive test results and choose whether they want to be seen personally or remotely.
“Things are already getting better. Today we have announced that we have achieved our goal, seven months earlier, to deliver more than 2 million additional meetings for chemotherapy, radiation therapy, diagnostic tests for endoscopy and others. “
