Patients arriving at major A&E departments in England for treatment were seen within four hours in fewer than two thirds of cases last month as the NHS failed to meet its targets.
There have been many cases of people in recent months waiting more than 12 hours for treatment in hospitals around England as the NHS attempts to improve the statistics.
People can check out how their local NHS is performing with some areas fairing better than others.
The NHS aims to see 76% of A&E attendees within four hours, a target which has been temporarily reduced from 95%.
Despite this though, only 61% of patients in April were seen within this time at major A&E departments across the country.
That figure improves to 75% if you include all types of A&E, such as walk-in centres, but it is also below the reduced target.
While the statistics are worrying, it is an improvement on last month as just 57% of arrivals at major A&Es and 72% overall in March were seen within four hours.
There was also an improvement in the number of people having to wait more than 12 hours to be admitted.
A total of 26,899 patients had to wait over 12 hours from a decision to admit to being admitted in April. That’s down from 39,671 patients in March.
Meanwhile, the Government has missed a key target of eliminating 18-month waits for planned NHS care such as knee and hip replacements, official figures show.
Data from NHS England shows 10,737 people were waiting more than 18 months to start routine treatment at the end of March.
This is down from 29,778 at the end of February.
The Government and NHS England set the ambition of eliminating all waits of more than 18 months by April of this year, excluding exceptionally complex cases or patients who choose to wait longer.
But the latest data shows this target has been missed, with 41% of the 10,737 cases falling into the category of people choosing to wait or exceptionally complex cases. This means 59% of the cases are routine waits.
Almost half of those waiting are believed to be concentrated in 10 NHS trusts.
In January, Prime Minister Rishi Sunak pledged that NHS waiting lists will fall and people would get the care they need more quickly.
However, the figures released today show that the number of people in England waiting to start routine hospital treatment has risen to a record high.
An estimated 7.3 million people were waiting to start treatment at the end of March, up from 7.2 million in February.
The data also confirmed that a key 62-day cancer target has also been missed.
The Government and NHS England set the ambition of returning the number of patients waiting more than 62 days to pre-pandemic levels by March 2023.
The new data shows that the number of patients waiting longer than 62 days since an urgent GP referral for suspected cancer stood at 19,248 in the week ending April 2.
The average weekly figure for February 2020 (covering the four weeks to March 1) was 13,463.
In January, NHS England wrote to trusts saying all patients who had been waiting 78 weeks (18 months) or more should have a "first definitive treatment scheduled before the end of March 2023".
The letter said: "We are... asking every organisation to book appointments for all of their 78-week cohort (patients who will otherwise breach by April) by the end of January, with outpatient appointments and treatments completed before the end of March."
Mr Sunak said on Thursday: "I promised I would cut NHS waiting lists and we are delivering.
"Reducing 18-month waits by over 90% is huge progress, and it is testament to the hard work of NHS staff who have achieved this despite one of the busiest winters on record.
"We still have work to do, but backed by record Government investment and the ongoing efforts of the NHS, I am confident we will get patients the care they need more quickly."
Health Secretary Steve Barclay said: "Cutting waiting lists to ensure people get the care they need more quickly is one of the Government's five key priorities.
"Thanks to the hard work and dedication of healthcare staff backed by Government support, the NHS has now cut 18-month waits by more than 91% - a significant reduction from the peak which saw almost 125,000 people waiting for treatment.
"Today's significant milestone shows we're delivering on our Elective Recovery Plan despite NHS strikes and the challenging winter.
"This comes after virtually eliminating waits of two years last summer.
"We are progressing with our plan including improving access to emergency care, with the latest statistics showing the quickest ambulance response times for the most urgent cases in almost two years.
"We will continue to work with the NHS to pull out all the stops to cut the Covid backlogs, backed by up to £14.1 billion over the next two years on top of record funding."
NHS chief executive Amanda Pritchard said: "The great strides the NHS is making on long waits, urgent and emergency care and cancer services in the face of incredible pressure is testimony to the hard work, drive and innovation of frontline colleagues."
Shadow health secretary Wes Streeting said: "Rishi Sunak has broken his promise to end 18-month waits for NHS treatment, leaving thousands of patients in pain and discomfort for unacceptably long.
"This is just the latest broken promise that shows you can't trust the Tories with the NHS.
"Ministers blame strikes, as if they are mere bystanders. It was their refusal to speak to nurses and junior doctors that forced them out on strike in the first place.
"Labour will give the NHS the staff it needs to treat patients on time again. We will abolish the non-dom tax status to pay for training 7,500 more doctors and 10,000 more nurses a year."
