A Patient survey has rated Northwick Park Hospital as having the eighth worst healthcare standards in the country.
Hundreds of patients gave their views on the levels of hygiene, treatment, food quality and privacy in a nationwide questionnaire, distributed by independent watchdog The Healthcare Commission.
Each NHS trust was given an overall care rating out of 100, The North West London Hospitals NHS Trust, which is also responsible for Central Middlesex Hospital, in Park Royal, was awarded 71 - the sixth worst in the capital.
Hitesh Nagar, 38, from Alperton, agrees with the low ranking after his experience at Northwick Park, in February.
The father of three said: "I would not recommend anyone to go there.
"My wife was pregnant and had to have an emergency cesarean, but it was botched. She had to have five post-birth operations to repair her torn uterus and ended up needing a hysterectomy.
"We felt doctors were keeping information from us."
The two hospitals were ranked among the lowest in the country for cleanliness of toilets and wards, waiting times for beds once patients were admitted and the quality of support for patients with worries and fears.
Fourty-eight per cent of people rated the wards as fairly clean and 13 per cent said they were not clean at all.
The quality of food was also criticised with 23 per cent rating it as poor and 37 per cent as fair.
Former nurse, Councillor Lurline Champagnie (Conservative), said the standard of care has deteriorated over the years.
She said: "There is a problem in the NHS. The standard of care is just not up to scratch and I put it down to discipline and the training of nurses and matrons.
"There is a lot of money being pumped into the health service but it is not improving."
Trust bosses have now vowed to improve standards.
Chief executive, Fiona Wise, said an action plan would be drawn up, but was quick to point out that only two per cent of patients responded to the survey.
"We are disappointed by some of our results and also by the low response rate from our patients," she said.
"We take the feedback seriously, as it is a good indicator of where we need to make improvements as well as where we are doing a good job.
"The majority of the issues raised in the survey mirror what we see in the comments and complaints we already receive from our patients."
