Total knee replacement (Unilateral) in 605 Orthopedic surgery clinics worldwide

I went to see an OBGYN at NTU because I had been having pelvic pain for about 2 weeks at that point. I'd felt similar discomfort before when I'd had an infection, so that was my best guess. The OBGYN did a very perfunctory pelvic exam and declared it couldn't possibly be an infection or related to the gynecological area because it didn't hurt when he pressed externally on the pelvic area, so I left with no treatment. That night, I had to go to the ER for stabbing pelvic pain and bleeding and was diagnosed with a bad pelvic infection. In summary, would very much recommend Taiwan Adventist Hospital's OBGYNs (called specially to the ER - so thorough, caring, and efficient) over NTU (for gynecology anyway).

I was at the start of a month long vacation and needed an emergency spinal epidural. I met with the neurologist, Dr Chang, who was able to perform the procedure the next day. This was probably the best medical treatment that I have ever had. And the cost was $172 USD. Here in the US, the same thing cost over $2k. I highly recommend this hospital.

Excellent doctors, nurses, and staff. Surely they can find a better way to organize their elevators? They have treated my elders in thoughtful and humane ways. We are grateful.

Have been passed around from test to test for 3 months trying to get clearance for surgery without any treatment for my condition. Seems like all they want to do is test and not treat problems. Impossible to contact doctors offices by phone. Ordered tests without telling me. Asked for referral to hand surgeon and they sent me to shoulder specialist. Asked for referral to ear doctor and they sent me to throat doctor. Did multiple tests on heart and all good but they are ordering more tests. Think they are more interested in generating revenue than healthcare

My first bad experience, I have been admitted here several times and my stay had always been good, until today that I already have 6 days admitted with my son here we had a double room where the first nights I was touched by very decent and respectful people, the last two nights I have been touched by a couple with their son who leave the light on until late at night, they spend the day in phone calls and with a very inadequate tone of voice, the husband stays to sleep and has an awful snoring because those that are very difficult For me and my baby to have rest time! I talked to the manager who didn't do anything, I don't talk to people or take the delicacy to even see if she could move us to another room I don't care if it was with another person maybe they weren't as indecent as these which the sick people have told her that please if they can keep their composure and they don't even change! The truth is that I would have liked to have another person to help me and be more condescending with the situation, because I have seen empty rooms since last night even double, but according to the person I spoke they were not available! I'm still here and I can't take a break! As a hospital you need to put some rules like do not let man stay at least in double bedrooms, do not permit loudly noise in the room and for the residents on the rooms to keep respect to others and peaceful space appropriate for recovering!

My sister had surgery at Columbia Presbyterian Hospital. Her surgeon called me at 11:14 to report that she was out of surgery, and that the recovery room staff would be in touch when we could see her. I did not hear from the recovery room, so I called them. The desk clerk rudely told me that the nurse would call. It is now 2:50 - almost 4 hours since my sister left the OR, and I still have not heard a thing from the recovery room nurse. It is inexcusable to treat family members in this way. In addition - they have a one way texting app for communicating with family members - useless, apparently, because they don't use it. I understand nurses can be extremely busy, but it only takes seconds to communicate to worried, waiting loved ones.

Seems like a reliable place but at 5.5 months pregnant I went to receive a regular check up and it ran me $400. Also, there were tests done in that checkup from blood work. Still have yet to receive any results from the blood work. Also I specifically told the doctor not to tell me the Sex of baby as it’s a surprise & we were doing a gender reveal and she laughs in my face and says “It’s a boy…It’s not a surprise anymore” Ruined my gender reveal for me & my son with 0 sympathy. I never want to go back to this hospital again.

Had cholecystectomy done here. Everything went well. Nurses and doctors are very professional, polite, and friendly. The room was good and big. Like the food as well

Big hospital with modern facilities and equipment. Caters for both local and expatriate community. Attentive and good service. Has all aspects of hospital care.

Organized, clean, friendly staff, I was able to get a same day appointment and a minor procedure done. It was well orchestrated. I’m super pleased. Beautiful facilities. Special shout out to Dr. Irin Chowchankit.

Highly efficient and professional services for emergency and surgery for a close friend who suffered a serious femur fracture at her hip. Friendly, caring, and professional medical staff. Very impressive facilities and services.

While I appreciated the procedure being done my beef is this places billing department only affords you 6 months to pay your balance. So even tho I have insurance through my place of employment and reached my déductible prior to surgery, and even though I have been making payments monthly for the remaining 20% ... if my balance isn't paid in full within 6 months their "policy" is to send it to collections. Now I was offered 'financial assistance' IF I submit two or three years of taxes, plus several paycheck stucs. (So basically all of my personal information) which is not only time consuming but also invasive. I'm just a single gal trying to make ends meet. I needed the surgery to prevent further complications down the road so I elected to have it done. Perhaps I missed information prior to getting the surgery? But I NEVER thought that even though I am paying monthly a fair amount towards the remaining balance that I would STILL be threatened with having it go to collections. And just for that reason I would NEVER recommend this place to anyone. Period

The Nurses, CNAs, PTs, & Staff were all AMAZING!!! My mom had knee surgery a week ago and our experience there was great!! Everyone was kind and helpful from admission to post op. I can’t remember everyone’s names but I did take some down! We loved how kind and helpful her nurse Kaylani was!!! The most important part to us was having a Spanish speaking nurse on staff. My mom only speaks Spanish and it was so comforting to us knowing at night she was left with someone she could understand and communicate with! Thank you to Josephina and Nasthja for taking such good care of my mom! The physical therapist, Ruth is incredible!!! My mom adored her and made us feel confident about taking her home!! Special thank you to KASS, CNA!!!! She provides excellent patient care. Spine and Joint hospital provided quality care!

Arizona Spine and Joint Hospital gave me outstanding service and care during my stay. I would also like to thank Dr. T, his wife Kate, and Dr. Kralik for their great skills and knowledge. I'm so thankful my wife and I found these skilled surgeons. I'd also like to thank the nurses and staff who took care of me while there: Debbie, Cathy, Karen, Deanna, Becky, Dickson, Katherine and Veronica! Thanks again. My drive from Lake Havasu was well worth it!

Couldn't visit my grandpa in the emergency room. I drove an hour to get here and then they tell me there is a 2 visitor limit. There is little to no reception in the building so I couldn't even get in contact with who was in there. I called into the room and when I asked about someone leaving she pretended I didn't even talk to her and went mhm mhm and hung up. I love hospitals that won't let a grandson see his grandfather in the ER

I am deeply thankful for the exceptional care and attention I received during my recent visit to the emergency department at Brigham and Women's Hospital. The doctors and nurses demonstrated genuine concern and provided excellent care for my difficulty swallowing, gastric issues, and rapid weight loss. Their professionalism and compassion made a significant difference during a challenging time. I want to express my sincere gratitude to the entire medical team for their dedication and outstanding support. Thank you for helping me through this health concern with such skill and kindness.

During my dad's ICU stay at Brigham and Women's Hospital, the nurses provided outstanding care. They kept us informed and made us feel safe throughout a traumatic time for our family. The level of expertise, compassion, and seamless coordination between day and night shifts was remarkable. My family and I will be forever grateful for Nurse Bryan, Katie, Kayla, and Lauren from Unit 3B.

My experience with the staff was a very special and good one of course there were a couple of not so greats but as a whole I totally appreciated the experience and staff!

My wife and I welcomed our first child with John Hopskins and we were treated exceptionally. Our stay lasted 6 days. Nearly every member of the staff seemed to truly believe in the work they were doing and it instilled confidence in my wife and I. The student nurses were very helpful and what they may have lacked in experience they made up for in drive and enthusiasm! Two of the nurses, who helped my wife in labour, even visited us the next day to congratulate us and check up on the status of our child. It did get busy for the nurses the last few days and we would love to have seen more lactation specialists on staff available to help us but after this incredible experience I will certainly encourage my wife and other parents to include John Hospkins in future family planning.

We had a very nice experience here. Dr Kuwera and staff took perfect care of our toddler. He was competent, thorough and friendly-explaining everything as he went. It’s a large hospital, but with many helpful staff stations throughout, it’s easy enough to find your way around. Must register before entering, which ensures safety. Very thankful for wonderful healthcare.

I had a cardiac ablation done by Dr Blatt and the experience was excellent. From the moment we walked into the hospital and the information gentleman took us to the surgery unit, the intake gentleman, without exception every person we came in contact with was friendly and helpful. My nurses were all exceptionally great. The hospital's sophistication, cleanliness and features were top notch.

On 11/7/2023 During my 5 hour stay the dr and nurses gave me a horrible experience. My monitor was going off for a good while because I had a high heart rate and no one came to check until after 5-10min once the beeping got louder. After couple hours passed and I really needed to urinate, I wait to see if anyone would check on me because I know how busy the hospital gets and after that waiting for a long time and trying to wave down nurses who would just look at me and walk away or say we’ll be there when we can. Yet I seen them just hanging out talking in the hallway of the hospital from time to time. My curtains weren’t closed all the way hence why I could see what they were doing. I ended up urinating all over myself because I couldn’t hold it anymore and I wasn’t able to disconnect myself from my Iv and the other monitor with my blood pressure heart rate and the sticky stuff attached to my body that looked almost like an ekg machine to monitor me. I had to sit in my own urine for about an hour or so till someone came to check on me, I have never felt so neglected in my life. They offered me some wipes to wipe myself and some of the hospital underwear(not real underwear) they had also left a syringe w/o needle on the bed I was laying on. Then upon discharge they gave me my paper work went over everything briefly and disconnected me from the Iv but not the monitor and I was still connected so I had to disconnect myself and take it off. The dr stopped for literally a few seconds saying your labs are good and left. This was my worst experience ever!!

Front desk at the ER the lady where the "red star is" very disrespectful. The RN Kristy I had her today room 29 at the ER nicest person ever, she was great, attentive, respectful, explained every step, overall I felt cared off even though it was just a stomach pain. Thank you Kristy. 😊

You will roll the dice with anesthesiologists at this facility. I was "assigned" Dr. Traylor. A freakishly large, imposing and intimidating man with zero resemblance of care or compassion. I'm sure he chose this field because no one would EVER seek his services. His patients haven't a choice. He suggested a female doctor. Best suggestion he's ever made. In walks Dr. Sarah Cocoma complete with a raging eye infection. This woman SNUCK behind my bed, DISTRACTED me and FORCEFULLY shot VERSED in my IV. It burns given gently. To render me unconscious, without asking, warning or care. Filthy conditions in every area including the elevators. Stay away from the trauma this place leaves behind. You've been dutifully warned.

The worst communication. Terrible gaslighting. The INEXCUSABLE FILTH in this facility. It was everywhere. The waiting room, the bathrooms, the hall was littered with garbage type red biohazard bags. Even INSIDE my Operating Room...garbage on the floor. When I objected to what I was seeing, they promptly canceled my surgery. I couldn't get out of that place fast enough...but not before one last gross show of filth, the floor of the elevator was littered with 2x2 gauze pads...soaked in something orange. I quickly pointed it out to my husband so he can see for himself what I was trying to describe. He quickly understood as an employee's foot was standing over some ofthem. My biggest fears were handled BEAUTIFULLY by this pre-surg staff, they are willing, if able, to accommodate women patients with women doctors/ residents...they allow small gestures of modesty and that is commendable. And just so you know...all those personal questions they ask you? And all the personal questions you ask them? EVERYONE CAN HEAR YOU...as there only curtains for privacy. HIPAA laws must be out back on a smoke break with the 3 janitors this place employs. 2 thumbs down and shame on you.

Had a good experience. Brought my father in law into Rush to be evaluated from stroke he had 3 weeks ago. They had him in a bed in less than 30 min. He was admitted and put into their stroke rehab program in less than a week.

Last summer I ended up in the ICU for 6 days with a pulmonary embolism. All the staff were wonderful, especially the nurses who changed my chux pads. Multiple doctors came to talk to me about my options, and I felt reassured that I was in good hands. I was put in a catheter-directed thrombolysis study. My medical team explained the procedure in ways that my oxygen-deprived lungs could understand, and before I knew it I was rushed to the OR. My follow-up care at MGH has been exceptional. I see a cardiologist and hematologist regularly now, but I am grateful to be alive thanks to the wonderful staff at MGH. You all rock!

My wife was operated on 10/19. Our stay from then on and through the weekend was the best hospital experience to date. We especially want to comend the staff. Our nurse Lauren Schmidt was the happiest and most cheerful which flowes right to the patients making us feel great. All the staff was great.

Boston was going to be just a port of call on our cruise, but we had a medical emergency while we were here. We spent some time in a very busy emergency room, but they got us in for surgery within 24 hours. All the medical professionals who helped us were kind and very informative and caring.

Worse Possible Care Provided: I chose Medicover for my Child Birth Due to below reason. 1. Language Barrier: Medicover People Speaks English so it should be easy. 2. Reviews and Facility : With 1st visit you will be impressed with the facility and I aggree facility was good. What Was good: 1. Initial Checkups to check baby heart Rate. 2. Few Nurses(I can count on fingers) which were really good and served really well (be it Delivery or after care) 3. Alertness of Pediatrec Doc: Thanks to his alertness we caught hold of my baby's sickess at very early stage. What was worst: 1. Except one Nurse : No Nurse speaks English in Baby Care Department and except few no nurse speaks English in mid wife section Inspite of knowing that neither me and nor my wife speaks Hungarian : Out of 3 nights Spend: for 2 Nights there were none of nurse were speaking English and my wife had to make them understood using google translate and that too her already painful condition. 2. Food Quality: Worst possible food is given for vegetarians. One on hand doc was saying to avoid food which could cause gas and on other hand Gaseous foods are being served from Medicover! 3. Here comes my worst nightmare which is still not stopped: My wife's sutures were not done properly and got infection in 2 weeks. for that Medicover re did them again(At Medicover cost) at 3rd week and after that start charging us for control appointment(2 times) and by that time Medicover just wanted to get rid of this case and finally doc said every thing is ok and come back after 3 months but my wife is still in pain so looking at such behavior from medicover we had second opinion and seems there the sutures done for second time also is not done correctly and there is gap and now it might need to lead another round of sutures. So in the end my wife's medical case is ruined by Medicover so I would put second thought for people who wants to go for them and inspite for paying an hefty amount of 800K HUF we are still doing rounds of hospitals just because team in medicover could not do their job properly !

I'm from the UK and had a hysterectomy operation done in Budapest. The operation was carried out in the utmost professional and skilful manner. I couldn't have ask for a better treatment or outcome. The staff were friendly, professional and attentive. I'm very grateful for the first class service I received.

I traveled almost 4 hours to get to the Medicover for my appointment, from Baranya. And waiting 10 minutes for me, because I was in a traffic jam, was clearly too much for this doctor. We even called to warn we would be 10 minutes late and the reception told us then it wasn't a problem.. Wouldn't recommend...

Easily the most efficient medical facility I have ever stepped foot in. Everyone is friendly and professional…the campus is a very nice place to spend time if you have to spend the whole day for a bunch of testing. Food service has recently been revamped and has dramatically improved. When you consider the volume of people seeking specialized medical care IN ADDITION TO a very active ER, I find it is nearly miraculous that I have never waited more than 15 minutes past my scheduled appointment time to see my Dr, and that is coming twice a year for the last 7 years. Not once…

Amazing experience at Mayo Clinic Jacksonville!! After three trips to our local ER all resulting in an undiagnosable abdominal pain and seeing literally one dozen doctors, we were blessed with a referral to Mayo Clinic and my husband was healed!!!!! No more prescriptions! No more weight loss! No more issue! They found the problem on the first visit, had it removed three weeks later and no more pain praise God!!!!! Thank you to the entire staff from the gentleman at the entrance with his cheerful greetings to the kitchen staff who keep even the most grumpiest of patients happy and fed we appreciate all of you there at Mayo!! Thank you from my family to yours!

The ER/ED staff is dismissive, taking forever to treat patients. I have been sitting in this damn hallway for 5 hours. Yes they have ran tests, no medication to treat any of my symptoms. Trying to discharge after doing nothing… Had to CRY to the doctor about how I felt my care wasn’t up to standard and then she eventually gives me meds. Mind you. After 5 hours. Thought Mayo was one of the best hospitals in the south. Will never be back.

Dealt with this hospital for several years. No matter what day or what doctor I've always been left with the same experience; cocky doctors playing God with the absolute worst bedside manner. Never again.

My husband was a heart transplant patient here. One time they failed to give an accurate report for him to adjust his warfarin accordingly. Subsequently he suffered a stroke and had to have intracerebral hemorrhage surgery. My husband overlooked a lot of things and this hospital had the nerve to kick him off the transplant list. They called an old number and then said that since they couldn't get in touch with him he was non-complaint. I gathered so much proof to show that they were the ones who made an error. I got all the phone records and proof that we updated his information but it was evident that they just wanted to get rid of him. I wanted to sue so bad but I left them all to God. You should have been in that break up meeting. By the grace of God he got his transplant at an excellent hospital in CA.

Lynn at the gift shop was extremely helpful and made ordering flowers a seamless process. She was so kind and patient too. Thank you Lynn!

We were at Vanderbilt before transferring to Mayo. This has been an amazing experience! It’s like it’s a requirement is to be super nice; Vanderbilt, not so much. I would recommend anyone to come here, and I’m so glad we chose to switch. The doctors, nurses, and even the staff (cafeteria, welcome center, etc) were by far nicer than Vanderbilt. They are so knowledgeable, thorough, and patient. Very impressed!!!

The Mayo Clinic is such a special place! It’s a medical facility that could also be a museum of art museum, history, and architecture. People travel from all over the world to be treated here, but what makes it truly special are the compassionate, skilled, and dedicated employees. I stood outside the Mayo Building and watched bus after bus pull up to the staff entrance - and watched countless everyday heroes get off those buses and go to work performing “miracles” at a place that provides hope to people who need it most.!!

I had 7 uterine fibroids removed by Dr Khan. Well done. No complications. After six weeks I was back in gym doing great. Dr khan is the best. Great doctor. Nurse Logan day shift and Susan night took good care of me.!!

I recently had a consultation at Dr Rose. I was told several times before going in for the examination that the price is 210 EUR. I even confirmed at the reception again before going in. After the consultation I was told it is now 360 EUR as the doctor did an ultrasound. I did not ask for this extra test nor was I told during the consultation that this test will add an extra cost to the agreed 210 EUR. After querying this I was told that I should’ve asked what my consultation includes as it’s my first time at the hospital!! I find this very bizarre as I book for what I need and confirm the cost before and they just take it upon themselves to add extra tests without asking the patient first and then request payment as the test is done now.

The ENT missed everything possible to miss .. probably bc he barely looked into my nose and mouth due to being scared of covid which is utterly reliable but he accepted patients yet I had my covid test so I refused to pay a penny more than 210€ which I assumed will take longer than what I had... missed my sinusitis in 2022, constantly felt ill and since the ' prestigious dr rose said nothing is wrong with my nose or throat ' I went to everywhere else..ended up having GERD from post nasal drip for months ....literally the ghettoest place for hight price..the view is beautiful but that's it...

I had an eye issue (retina) and Rose was the only place in Bp. willing to give me an eye specialist appointment. Excellent eye exam, assured me that I can safely travel back to the US for further treatment..

Hey Google Appeals team!! This is not a fake review, I went there and have an invoice to prove it! Review: A 6min doctor consultation for 100eur (35k HUF). No ultrasound which is usual. Just a short talk and that's it! Dr. Papp Gyorgy had not given me the appropriate time or attention for my medical condition. 6min in and out!

I highly recommend Duna Medical Centre. Professional, efficient, pristine offices, kind english speaking staff, state of the art machine (mammogram tomosynthesis). Dr Anett Szomják. Everything was super easy.

I had a very pleasant experience at the urology with Dr Buzogány István and his assistant. All the people I’ve met with so far in the center are very kind and helpful.

Super 👌

Very professional stuff. Waiting period is longer so needto be patient.

I had my total hip replacement surgery here six days ago and everything went great. Dr.Ravnihar is great and he took his time to make everything perfect for me. His staff at B2 ward is full of love for patients and find it not hard to do their job. One more thing that was very good to me. Food at this hospital is excelent and some restaurants might be envy of the cook here. All in all,if you need some joint replaced,come here and you will not be dissapointed.

Majority of our experience here has been great, however since we spend most of our time in the Nicu with our baby boy, you would think that the nurses who are watching them follow some type of guide to respectfully work quietly so that the babies who needs rest can rest peacefully, but no! That’s not the case, they gossip out loud with one another, they slam drawers, trash lids, and more. Our kid has a heart condition so resting is the best thing for him to get him where he needs to be for his surgery. He is always startled or woken up by all of the noises going on. All I ask is that you guys respect the needs of the kids who needs to rest and try not to make so much noise or talk so loud, especially if is just about gossip. Thanks

UCLA should be ashamed to call itself a hospital . I placed a negative review of UCLA, Ronald Reagan Hospital A few days ago and I see it it has been removed. First of all upon my arrival at the ER, after requesting That all of my doctors be within my network I was told by the person checking me in ( cold As a bottom of a rock ) it is against the law for him to tell me if the doctors are within network. Which I know is against the law in California. This place is basically not any better, and has lower standards than any Third World country hospital. If I was able to give it a zero or even minus I would. There was basically a dozen seats in the ER for waiting so as you are exposed to any illness. I was seen after five hours for a heart problem There is nowhere to charge your phone, so as to keep in touch with loved ones. People are spread out and strewn throughout the hallways ( including tents, just outside the ER ) with no privacy and total humiliation. The ER is full of homeless, looking for a place to sleep. I will continue to post continuously, until my experience is not deleted. If you have or care for your loved ones, do not bring them here like I said, this is below third world healthcare standards

I gave birth to my daughter here in early 2022 & will be giving birth here in early 2024. I wouldn’t want to go anywhere else for OB care. I live in Tarzana so the drive while in labor was not fun & I could have gone to a much closer hospital but I trust UCLA Westwood more than any other ER/OB department & can’t imagine having gone elsewhere. The labor & delivery nurses are compassionate, informative & kind. My Dr. Is Dr. Zapata but she wasn’t on call when I gave birth so I saw another Dr, so sorry I don’t remember her name, but she was amazing and I felt in very capable & caring hands. I recommend this hospital for anyone I know who’s pregnancy for maternal & postpartum care. I’m very surprised the rating isn’t higher as overall the doctors are wonderful, up to date, the nurses are very capable & always warm in my experience. Also, it’s such a well maintained campus with updated equipment & very clean overall.

I had a Tilt Test. All went on very well and efficiently. The reception process was very fast and efficient. My test started 10 minutes ahead of schedule. The doctor who performed it was very experienced and professional.

Horrific hospital ! Avoid at all costs! The hallways are dirty, the staff and equipment are straight fro the 1960s and you will spend upwards of 12 hours for any Simple checks. The level of medicine in Israel is simply dismal, how can such a rich country have appalling healthcare is beyond me . Very sad

Hospital? Can it be called hospital? Air fresheners everywhere , cannot breath, go outside to take fresh air, you get a wall of sigarrete smoke into the face. All together with parfumes, chemicals smells and other hell knows what smells. I think it is cannot be called hospital.

My partner Derek Baum underwent a small injection procedure at the Ramat Hayal hospital. I have no words for the level of care from the delightfully kind receptionist to the amazing nurse (Shira) and of course the doctor. Such a “pleasant” experience that I’m in awe of our wonderful Maccabi Health Service !! Thank you to all of the team who did Derek’s procedure this morning Wednesday 14th June

Supposed to be the best private hospital in Israel... I doubt it. My recommendation - even if the doctors are great, don't go there for Mei Shafir. You will get an awful treatment of your case. Let's start by the fact that they canceled the genetic consultant a week before the mei Shafir check.. and asked me to find a docteur (genetics specialist) that could see me in the next 3 days, so they could perform the check on time.. No help on their side to help me finding of course. So now imagine yourself calling every hospital of Israel asking for a place in the next 3 days to see a specialist... and how stressed you are. Found a place in Nahariya by chance. The specialist didn't even understand why I was being canceled from the beginning at asuta (what was found in my genetics tests was insignificant) . Even the mei Shafir doctor didn't understand why the genetics consultant of asuta was ever canceled to me!! Anyway check went well and today I am receiving the results... what a shame! 2 pages of results scanned, the second page cannot even be read. The first page is not clear. That's such a shame and so embarrassing. Anyway from my experience and people that went with asuta will confirm, your case with be handled by many people, no one has the same work process, no one will answer you clearly and on a same way. Choosing asuta is choosing to add more stress to your life.

Very fast CT checking wait for my doctor
