Delayed prescribing for upper respiratory tract infections: a qualitative study of GPs' views and experiences

Setting

This study was conducted as a part of the Prescription Peer Academic Detailing (Rx-PAD) study,19 a cluster-randomised educational intervention in general practice, with the aim of improving antibiotic prescribing in respiratory tract infections. The participating GPs were counselled by trained colleagues in their continuous medical education (CME) groups, and guidelines were presented to the GPs in a 1-day seminar. One of the authors held a discussion on the evidence for delayed prescribing.

Participants

Between October 2006 and September 2007, five focus groups were conducted, comprising 33 GPs who participated in the Rx-PAD study.19 Focus group interviews were considered an appropriate method to highlight views and divergent opinions.20 The participant GPs and focus groups were recruited using a purposeful sampling strategy, and the study aimed for variety in the sample with respect to geography, age, sex, and antibiotic prescribing rates. Table 1 presents the characteristics of the focus groups participants and the entire Rx-PAD study participants. For comparison, the characteristics of a reference GP population of Vestfold county 21 is presented.

Interviews

The first author acted as moderator for four focus group interviews, while the second author was the moderator for the fifth interview. Moderators used an interview guide that was developed by the authors, and which covered experiences and views of the GPs on delayed prescribing. Each of the focus group interviews lasted for 45–75 minutes. GPs were encouraged to share their views in an open discussion. All discussions were audiorecorded digitally. Preliminary findings and questions from the first interviews were fed back into later focus groups for further discussion.

Analysis

Audiorecordings were transcribed verbatim. The material was analysed using a procedure for content analysis referred to as ‘systematic text condensations',22,23 comprising the following four steps: (i) reading all the material to obtain an overall impression, and bracketing previous ideas and preconceptions; (ii) identifying units of meaning, representing different aspects of GPs' experiences with delayed prescribing, and coding for these; (iii) condensing and summarising the contents of each of the coded groups; and (iv) generalising descriptions and concepts about specific themes. All the authors took part in the analysis, and met to discuss the meaning of data and the interpretation of the material. NVivo7 software was used for coding. Quotes from interviews were translated from Norwegian to English by the authors.

Delayed prescribing as a concept

GPs used the term ‘wait-and-see’ both for scheduling a follow-up visit when needed and for the delayed prescribing approach. They described general practice as a branch of medicine in which it is common and often appropriate to wait and see: ‘[Intern doctors in primary care] think too much hospital, they want to solve [the problem] here and now and they don't use the approach that we are used to in general practice, to wait and see.’ (focus group [FG] 3)

General practice was characterised as a field where practical experiences stimulate the development of new methods, such as the use of wait-and-see prescription. None of the GPs had been educated in the use of delayed prescribing before entering the Rx-PAD study, but several of them said that they had been using the method for years: ‘It is within the spirit of general practice to start using a method that you think seems logical and correct … without having a scientific reason to do it. That is the GP's best quality. They make something smart out of it.’ (FG1)

The GPs considered themselves prudent prescribers, and they were well aware of the relatively low antibiotic prescription rates in Norway. Avoiding unnecessary use of antibiotics was seen as an important task, although they usually described delayed prescribing as a practical solution at the individual patient level.

One of the focus groups displayed mainly negative attitudes towards delayed prescribing. Members of this group argued that there were few situations where they used the strategy, and this was mainly when patients demanded antibiotics. One GP said: ‘I have used [wait-and-see prescriptions] for several years, but to a small extent only … It is for those who want medication, though you argue that they don't need it, but then they win at the end and I say: “Can't you at least wait for a couple of days and see how it develops?” You become somewhat pragmatic with the years.’ (FG3)

The other focus groups, however, were positive about delayed prescribing. They found the method useful in several situations where the question of whether to prescribe was not clear. They also reported that they did not experience delayed prescribing solely as a compromise:

Moderator (M):‘Some have said that [delayed prescribing] can be a negotiated solution, do you have that experience?’

GP1:‘No.’

GP2:‘No. Who should negotiate?’

M:‘The patient wants [antibiotics], the doctor doesn't want to give [antibiotics].’

GP2:‘That was 20 years ago.’ (FG4)

Medical conditions

GPs conveyed different views about what conditions they considered the most suitable for delayed prescribing. A widely held view was that delayed prescribing was appropriate in cases where GPs expected that the indication for antibiotics would be established within a few days. If they thought that additional observation would not add more information about whether to prescribe antibiotics, they would rather make that decision at the patient's first visit.

Some GPs argued that the wait-and-see strategy was feasible in cases where they were certain that the infection was caused by bacteria, but where the symptoms were mild; for example, a sore throat caused by streptococcal infection. GPs who held this view emphasised that in such cases, they knew antibiotics would be effective if needed. This view was opposed by other GPs who argued that infections with unknown aetiology were the ones most suitable for delayed prescribing.

Acute sinusitis was found to be the most suitable diagnosis for delayed prescribing. GPs considered bacterial sinusitis to be difficult to diagnose, and hence this was used as argument for delayed prescribing. One GP said: ‘[T]here are incredible few objective findings in sinusitis […] a matter of opinion and assessment of symptoms is used to make decisions about treatment, and in such cases I think I might use wait-and-see.’ (FG3)

Many GPs spoke about a certain group of patients with recurrent sinus symptoms, who consulted them too early during the course of illness and made demands for antibiotics. In such cases, the GPs could advise the patients to use non-antibiotic treatment options for sinus symptoms, such as decongestants and analgesics, as an alternative to prescribing antibiotics at the patient's first visit.

Children with acute otitis media were also seen as suitable for delayed prescribing. GPs reported that they found it easier to avoid prescription of antibiotics to children at present than several years ago, because parents had become more sceptical about antibiotics.

A third diagnosis that could be appropriate for delayed prescribing was acute bronchitis in situations where point-of-care tests could not clearly separate viral bronchitis from pneumonia.

Situational characteristics

The GPs said that they more often issued a wait-and-see prescription if a weekend or holiday was approaching; this was reflected in the notion of ‘Friday prescriptions'. It was important for the GPs to help their patients so that they did not have to seek after-hours care, because of the long distances and long waiting time at the after-hours care facility. In addition, the GPs reported that the after-hours care doctor might initiate treatment that they did not agree with, such as prescribing broad-spectrum antibiotics for harmless infections. The GPs, therefore, preferred to prescribe narrow-spectrum penicillin as a wait-and-see prescription prior to the weekend. Following this strategy also contributed to reducing the workload of the after-hours care doctors.

The GPs would more easily issue a wait-and-see prescription in their regular list patient practice than in the after-hours care setting, because the scope for follow-up was better in the regular office setting, and also because the GPs normally knew their own patients better than the after-hours care patients.

Characteristics of the patients

There was agreement among the GPs that delayed prescribing did not suit all patients. Patients considered eligible for delayed prescribing were said to possess characteristics such as being ‘knowledgeable’ and ‘bright’. The reason behind this thought was that patients with these characteristics would not violate the principle of wait-and-see and ‘misuse’ the prescription, and also to ensure that patients were able to evaluate their condition and make the right decision after the waiting period. One GP said: ‘The patient has to understand the message and has to participate in the dialogue, and that it is wise to wait a bit and see. Otherwise, if I prescribe a wait-and-see prescription to a patient who is not following me in a way, I do not think that he waits and sees at all, and then I resign instead.’ (FG1)

A patient was ascertained to be ‘knowledgeable’ if he/she agreed with the view of the GP that antibiotics should not be used unnecessarily, and if the patient knew the difference between viruses and bacteria.

The GPs said that patients' expectation for antibiotics influenced their prescribing, and might lead them to prescribe antibiotics despite a lack of a medical indication. Issuing a wait-and-see prescription could be appropriate in such cases; the GPs could at least ask the patient to wait a few days and maybe keep them from unnecessary antibiotic treatment. Often the GPs described a wait-and-see prescription in this situation in negative terms: they had ‘lost’ the argument and chose a pragmatic solution, rather than an ideal one. There were also patients who did not want to decide on the use of antibiotics themselves, as discussed by two GPs: ‘[It is] someone whom I know fairly well so that I know that it is not necessary to bring up the issue [wait-and-see prescription] at all. Yes, they want a clear answer. Either yes or no.’ (FG1)

GPs agreed that one should not suggest issuing wait-and-see prescriptions to patients who were unwilling or incapable of making a decision on whether to use antibiotics.

Informing the patient

The GPs emphasised that informing the patient was mandatory when issuing a wait-and-see prescription. Two main themes were identified regarding this information. First, the patient should receive thorough information and clear instructions about when to start the medication. This was to ensure that the patient understood that there was a proper judgement behind the use of delayed prescribing, and to prevent patients from demanding a wait-and-see prescription for any respiratory tract infection. One GP said: ‘If we just deliver a prescription and say “Start with the medication if you're not better in 4 days”, without giving more information about the condition and explain a little, then I think [the strategy] might have a slippery-slope effect. There needs to be a conversation to prevent this from happening.’ (FG3)

Second, many of the GPs, particularly those who were positive towards delayed prescribing, considered wait-and-see prescription as a ‘golden moment’ for educating and empowering the patient.

Summary of main findings

The study found that GPs viewed delayed prescribing as a method that was well suited to the spirit of clinical work in general practice, although their views differed on the usefulness of the strategy. The GPs who endorsed delayed prescribing emphasised shared decision making and the opportunity to educate the patient. GPs who were negative said that they mainly used the strategy in what they experienced as an uncomfortable situation of being forced to prescribe.

Mild and mainly harmless conditions that might be of bacterial origin, such as acute sinusitis and acute otitis, were considered most suitable for delayed prescribing, as opposed to conditions that were considered as purely viral, such as common cold. An important argument for issuing a wait-and-see prescription was to help the patient to avoid seeking after-hours care, especially during holidays and weekends.

For issuing a wait-and-see prescription, the GPs required that the patient was ‘knowledgeable’, able to understand the indications for antibiotics, and motivated for shared decision making. GPs emphasised the importance of informing the patient thoroughly when issuing a wait-and-see prescription.

Strengths and limitations of the study

Participating GPs had agreed to take part in the Rx-PAD study, which aimed to improve antibiotic prescribing. Therefore, the GPs may have exhibited a positive view towards methods that aim to lower the use of antibiotics. However, both high and low prescribers are included in the focus groups, and the antibiotic prescription rates of the participants are somewhat higher than those of a reference GP population.21

GPs were educated on the use of delayed prescribing about 1 year before the focus group sessions. This might have influenced the participants' views. Although the representativeness may be questioned, the study findings reflect a diversity of views and experiences associated with delayed prescribing, and the authors believe that these findings are valid for Norwegian GPs practising delayed prescribing.

Comparison with existing literature

Delayed prescribing was not endorsed by all GPs in the study. This is in accordance with Arroll et al8 and Kumar et al,24 who both found diverging views among GPs on the usefulness of the method.

In the literature, delayed prescribing is often referred to as a strategy for meeting the expectations of patients in situations where antibiotics are not indicated.7,8,15 In a study from New Zealand, Arroll et al8 found that the physicians' motivation for delayed prescribing was primarily to decrease unnecessary antibiotic use, and that the method strengthened physician–patient relationships by helping the physicians to cope with the pressure from patients expecting antibiotics even for the treatment of the common cold. In the present study, however, GPs viewed delayed prescribing primarily as a practical solution for meeting a patient's need, such as helping the patient to avoid seeking after-hours care if the condition worsened during a weekend, and not as a specific method for decreasing the unnecessary use of antibiotics. The common cold was not viewed as a relevant condition for offering a wait-and-see prescription.

The antibiotic prescription rate for URTIs is higher in New Zealand compared with Norway.25 GPs in the current study setting probably experienced less pressure from patients demanding antibiotics than the GPs in the New Zealand study. Delayed prescribing may thus be a feasible strategy in settings with both high and low patient expectations for antibiotics.

Although it can be claimed that delaying antibiotics has fewer advantages over avoiding them,15 most GPs in the present study reported indentifying numerous situations where they viewed delayed prescribing as a reasonable approach. According to the national guidelines for antibiotic use in primary health care in Norway,26 acute sinusitis and acute otitis media are the only two URTI diagnoses where symptom duration is one of the criteria for antibiotic treatment (7 days for sinusitis and 1–3 days for otitis media). These are also the two diagnoses that the GPs found most suitable for delayed prescribing. It can be concluded that delayed prescribing could be used as a tool to follow treatment guidelines in URTIs.

Implications for future research and clinical practice

Delayed prescribing is not endorsed by all GPs, but appears to be a feasible approach among informed patients with early symptoms of mild URTIs of a possible bacterial origin, such as acute sinusitis. It is critically important that GPs keep their patients informed properly when they decide to put them on a wait-and-see prescription. Delayed prescribing has the potential to reduce unnecessary use of antibiotics in sinusitis,27 but further research is required to explore the effect of delayed antibiotics on the clinical outcome of sinusitis.
