Check-ups in general practice and hospital

Once a diagnosis of mild or moderate kidney impairment (chronic kidney disease stage 1-3) has been confirmed by repeated blood and urine tests over a three month period, people with this diagnosis should be monitored by their GP through regular testing. According to NICE guidelines [2014] monitoring should be conducted between once a year and two or more times a year depending on the level of kidney impairment. People who have other long term conditions that require regular monitoring, such as diabetes, high blood pressure or cardiovascular disease, may have their kidney function tests incorporated into their existing check-ups and may not realise that this is being measured in blood and urine samples alongside other things.

Bernard knew his kidney function was being tested with blood and urine samples as part of his regular diabetes check-ups; he doesn’t mind having tests done.

Elizabeth learned recently when entering into a research study about kidney impairment that her kidney function has been monitored for the past 6 years but she hadn’t been told.

Kidney performance can be affected by certain medicines, such as non-steroidal anti-inflammatory drugs (used to treat pain and inflammation) and angiotensin-converting enzyme (ACE) inhibitors or angiotension receptor blockers (used to treat high blood pressure and heart conditions). Regular testing is needed to check the stability of kidney performance in people who are taking these medicines.

John has started taking an ACE inhibitor to lower his blood pressure and will be monitored to ensure this drug does not adversely affect his kidney function; in future all his health conditions will be monitored through a single blood test.

Joanne takes lithium for bipolar disorder and has regular blood tests to check her lithium levels and also her thyroid and kidney function since both can be affected by lithium.

Among the people we spoke to the frequency of check-ups varied enormously depending on the person’s particular health problems and what tests were needed. People taking warfarin because of cardiovascular disease had a blood test to measure their blood clotting time (or INR – International Normalised Ratio) every one to four weeks. Other kinds of check-ups ranged from every two months to once a year, the most common interval being six months. Some attended their GP surgery annually for a general health ‘MOT’; others for a medication review. A few people said their check-ups didn’t seem to be organised at any particular time interval but tests would be done when they were consulting their GP or practice nurse for other reasons, or if they asked to have checks done. Kath and Lesley said that they had tests done on joining a new practice. Jill and Sarah had only recently been diagnosed with CKD and didn’t yet know how often they should be monitored.

The frequency of Gerald’s check-ups with his GP has reduced from four times a year to twice a year because his test results were stable.

Once a year Flo has blood and urine samples taken and her weight and blood pressure checked by the practice nurse. When the test results are through she sees her GP for a medication review.

Kath says her kidney function has not been checked regularly but tests were done when she moved to her current practice and since then on the rare occasions that she goes to the surgery with a problem.

The way that check-ups are arranged also varied among those we spoke to. In many cases the practice contacted the patient to remind them that their check-up was due, sometimes by phone but more commonly by letter inviting the patient to book an appointment. Occasionally the letter would include an appointment date. Some people said they were alerted to the need for a check-up by the annual review date printed on their repeat prescription. Other people said that the onus seemed to be on them to remember and book their check-up appointments.

Bill receives a letter from his practice asking him to make an appointment with a nurse for his check-up, and while he is there they make a further appointment for him to discuss his test results.

Martin had a check-up with his GP this morning because when he picked up his medicines from the pharmacy recently a note had been included saying he had gone past his annual review date.

In the past, monitoring of people with all stages of CKD was done at hospital renal (kidney) clinics but nowadays people diagnosed with stages 1-3 CKD are usually monitored by their GP. Some of the people we spoke to who had been diagnosed a long time ago had started out being managed by the renal clinic but their care had been transferred to the GP after a period of months or years. For those who had check-ups at the hospital clinic the frequency varied between every month and once a year.

Robert had tests at the renal clinic every month for about five months before it was decided in discussion with the specialist that he could be monitored by his GP instead.

Simon and Flo decided to continue to see a kidney specialist (nephrologist) as well as their GP because they had more trust in the specialist’s expertise. Flo’s renal consultant had overruled a GP’s decision to change the type of statin Flo took to lower her cholesterol.

Simon explains why he likes to see his kidney specialist once a year as well as his GP several times a year; his consultant had been on hand to clarify his suitability for an unrelated hospital procedure.

Although Flo has her blood tests taken at the GP surgery in preparation for her annual consultation with a kidney specialist, the consultant does not automatically get told when the results are available on the hospital computer.

Jim B had started out having his kidney function monitored at the renal clinic, was then monitored by his GP for some years before being referred back to the renal clinic. He feels he was left in the dark by his GPs about his declining kidney health and that they should have acted on it sooner.

After his kidney function stabilised Jim B was discharged from the renal clinic to his GP. He was unaware that his kidney function was still a concern and sometime later it deteriorated to a point where he needed specialist care.

There are specific guidelines for when GPs should refer people with kidney impairment to specialist care, such as if their kidney performance drops below a certain level, or if there is a sustained decrease in kidney performance. Peter had started out having his kidney function monitored in general practice but had recently been referred to the renal clinic when his eGFR (estimated glomerular filtration rate) dropped to 30; following changes to his medication it has now risen to 40.

Some people who were having their kidney performance checked in general practice wondered whether they should also be seeing a kidney specialist (nephrologist). This was particularly the case among those who felt a need for more information about their kidney condition than their GP had so far supplied.

Lesley had struggled to obtain information from her GPs about her kidney problem and was worried that it might suddenly deteriorate. She would like to see a specialist but didn’t feel she could ask for a referral.
