Urinary tract infections (UTIs) are one of the most common conditions seen in female patients in general practice accounting for 1–3% of all consultations each year.1 Diagnosis of UTI is based primarily on signs and symptoms.2 If patients present with both dysuria and frequency, the probability of a UTI is greater than 90%, making the diagnosis of UTI (without the need for urinalysis) almost certain.3 Symptomatic treatments available over the counter (OTC) from community pharmacies include alkalinising agents, cranberry products, and analgesia. Although urine alkalinisation (for example, with potassium or sodium citrate) has traditionally been used to relieve UTI symptoms, there is little evidence to support its use.4,5 Antibiotic treatment is frequently unnecessary as uncomplicated UTI is often self-limiting and resolves in a few days without treatment.6,7 However, in non-pregnant women with moderate-to-severe symptoms, a 3-day course of trimethoprim (200 mg twice daily) or nitrofurantoin (50–100 mg four times daily) is recommended and can shorten the duration of symptoms by 1–2 days.7,8
The modern patient-centred NHS is committed to ensuring better, local, faster health care, putting the interests of patients at the centre of reforms thereby offering greater choice in how, when, and where to access healthcare services.9 Community pharmacies provide convenient access to a qualified healthcare professional without an appointment and routinely advise on minor ailments, including UTIs. As community pharmacists are already familiar with symptomatic UTI management, supplying trimethoprim from community pharmacies under patient group direction (PGD) for uncomplicated UTIs could improve patient access and extend treatment options.10,11 A PGD is a:
‘ ... written instruction for the supply or administration of a licensed medicine in an identified clinical situation where the patient may not be individually identified before presenting themselves for treatment’.11
An NHS Greater Glasgow and Clyde study undertaken in 2010 in 20 community pharmacies identified patient and pharmacist support for improved access to effective treatment from community pharmacies for patients with UTI.12 Inappropriate overuse of antibiotics was a concern for participating pharmacists but they supported treatment provision for this indication via a PGD. Despite the supply of trimethoprim under PGD from community pharmacies being novel in Scotland, it is used in some NHS care trusts (PCTs) in England and Lloyds Pharmacy has recently introduced an online doctor consultation service for the treatment of cystitis.13
How this fits in
Evidence for the use of the many symptomatic treatments available from community pharmacies for UTI is unconvincing. There are currently no patient group directions (PGDs) for the supply of trimethoprim via community pharmacies in NHS Scotland and despite their use in community pharmacies in many NHS primary care trusts in England, there are no published studies evaluating PGD use. The study found demand and support, from both patients and pharmacists, for antibiotics to treat UTIs to be available, without prescription, from community pharmacies. Within PGD controls, antibiotic treatments for UTIs could be provided via community pharmacies to improve patient access to treatment, which may also maintain antibiotic stewardship and reduce GP workload.
The study, aligned with NHS Scotland’s policy and quality agenda, examined the opportunities for trimethoprim supply under PGD and compared the pathway of patients attending general practice services with those receiving a new model of service provision via community pharmacies.9,14–18
