Introduction

Acute urinary tract infection (UTI) is one of the commonest acute bacterial infections among women. 1,2 Conventional diagnosis relies on identifying a potential urinary pathogen from culture of a mid-stream specimen of urine (MSU) in a symptomatic patient. The standard for reporting in most previous research and clinical practice was 10⁵ colony-forming units per ml (cfu/ml);3 however, lower colony counts are associated with symptoms and respond to treatment,4 only 5% of low counts remit, the rest remain symptomatic, and 50% progress to high counts with symptoms. 5,6 However, although both the American Society of Microbiology (ASM) and European urinalysis guidelines have recently recommended reporting much lower colony counts6 (10³ and 10² cfu/ml respectively), little research has used these standards.

In clinical practice the universal use of MSUs is probably not cost-effective; empirical antibiotic treatment is advocated. 7 However, the problem with universal antibiotic use is the growing problem of antibiotic resistance8,9 (now 20% of laboratory specimens). Thus, a key question is whether we can use history and physical examination, or near patient tests (NPTs), for better diagnosis and the targeting of antibiotics?

Symptoms

A recent systematic review3 identified nine studies that related symptoms and signs to diagnosis; however, it documented significant limitations:

• The authors identified few studies with ≥ 50 consecutive patients or independent blind comparison of symptoms and signs with a gold standard among patients with suspected UTI – in particular, none in primary care; 50 patients are also much too few to be adequately powered for symptom prevalences of 20–70%.

• The predictive value depended on setting (e.g. secondary care) and inclusion (e.g. some studies included suspected vaginal infection)

• Only one study – rated poorly methodologically – assessed the predictive value of combining symptoms.

• None explored the implications of the severity of reported symptoms nor used recent diagnostic standards. 6

Near patient tests

Dipsticks are the most widely used simple NPT in primary care. 10–13 Summary data are available of studies that assessed nitrite and leucocyte esterase separately, but primary data are needed to assess the independent predictive value of all dipstick results. 14 A systematic review suggested that the evidence base for dipstick use in primary care is poor because of the paucity of studies and ‘spectrum bias’. 13,15,16 Studies from primary care have a range of one or more limitations:9,11,15–19 they have not assessed the independent value of dipstick results and symptoms (hence potentially overcomplicating clinical decision rules); they have not used the range of dipstick variables (most include nitrite and leucocyte but not blood); they have failed to develop and then test algorithms in separate samples (the study by McIsaac et al. 19 being the exception); and/or they have low power. Only the most recent dipstick studies17,19 have used the recent more rigorous laboratory guidelines for diagnosis. Evidence from emergency settings suggests that dipsticks may be particularly helpful when clinical assessment indicates an intermediate probability of infection. 17

An adequately powered study was therefore needed:

• among women presenting in primary care with suspected UTI

• to assess the independent predictive value of symptoms, all dipsticks results and their combination

• to develop the simplest possible clinical scoring methods for clinicians to remember by determining the most predictive variables using multivariate methods

• to use more sensitive laboratory gold standards.

Conclusion

Simple decision rules could improve targeting of investigation or treatment, but strategies to use such rules need to take account of their limited NPV. Further research is needed to confirm the validity of these findings in a separate sample.

Introduction

The previous chapter reported a validation development study in which a clinical score and a dipstick score were developed based among women presenting in primary care with suspected UTI. The predictive value of any scoring system that is tested in the same sample used to compute the scoring system is likely to have artificially inflated predictive values; therefore, both a training and a validation set are needed. To estimate the more realistic predictive values of these scores, we assessed the predictive value of their components and of the scores in a new validation sample.

Methods

Analysis

We assessed the variables found to be predictive from the previous study in multivariate logistic regression. We also assessed the previously developed clinical scores by cross-tabulation, computed any new scores based on simple counts of the rounded logistic coefficients and determined the receiver operator curve for each score. The performance of each score for different cut-offs in the score was assessed. At each cut-off we determined the sensitivity, specificity, PPV and NPV, LR +ve test; sensitivity/(1–specificity), LR –ve test; (1–sensitivity)/specificity, and the number above the cut-off.

Results

Discussion

Conclusion

The pattern of clinical information in suspected UTI is of limited value in increasing diagnostic precision among patients with suspected UTI; although UTI is likely among patients with dysuria, nocturia and urine cloudiness, the absence of these features performs poorly in ruling out UTI. A dipstick rule modestly improves diagnostic precision but, in applying the results of dipsticks, clinicians will still need to take account of the limited NPVs, which are much lower than expected from previous research; even when all results are negative, 24% of women will still have UTI. This means that in practice clinicians should consider using strategies such as delayed prescribing for such patients33,34 – or alternatively advising a review consultation – if symptoms are not settling.

Background

Method

This study was largely nested within the diagnostic studies described in Chapters 1 and 2.

Analysis

We calculated means rather than medians because with small numbers medians are less sensitive to group differences. We assessed predictors of illness duration by negative binomial regression (because of overdispersion of the data). Linear regression was used for the symptom severity data. To assess potential confounding variables, variables significant in univariate analysis (p < 0.05) were entered into multivariate analysis and retained if they were significant; all of the univariate variables were then tested in the model and any further significant variables retained. To assess the pattern of symptoms in the period immediately after seeing the doctor when symptoms were most severe (days 2–4), we used factor analysis with varimax rotation and assessed the internal reliability of the scales using Cronbach’s alpha statistic.

Results

A total of 843 women took part, of whom 839 gave MSUs to their GP and 830 filled out baseline symptoms with their GP; 684 (81%) provided some information about symptom duration, and completed diaries were returned by 541 (64%). In total, 511 of these women had an antibiotic resistance status that could be classified (Table 12). The baseline characteristics of those women who were followed up and those who did not provide diary information were very similar for key symptoms (urgency, frequency, nocturia, dysuria), which suggests little response bias.

When an antibiotic was prescribed, a trimethoprim was used most frequently (> 80% of cases).

Discussion

This study documents prospectively the natural history of the more severe symptoms for patients presenting with suspected UTI (i.e. including the urethral syndrome), and documents the roles of antibiotics, antibiotic resistance and other key variables in determining such outcomes. The findings suggest that there is a role for doctors to be enabling and positive about the natural history and provide useful information about which variables predict natural history (a past history, somatic symptoms, the severity of baseline symptoms) and the likely major role of both antibiotics and antibiotic resistance.

Conclusion

At presentation to their GP the majority of women in the study suffered from multiple symptoms rated as a moderately bad problem or worse and half felt unwell and had a significant restriction in daily activities. Doctors should probably remain positive about the natural history for patients with suspected UTI. Patients with a past history and those with frequent somatic symptoms and severe baseline symptoms can be given a realistic indication that more severe symptoms may last longer than the average 3 days. Antibiotic resistance or not providing antibiotics is associated with a 50–60% longer duration of more severe symptoms and more severe frequency symptoms in the days immediately after presentation.

Background

Urinary dipsticks are used very widely in primary care and are the most commonly used NPT. The aim of using dipsticks is to try and target treatment to the 60% of women who have UTI whilst minimising antibiotic use for women who do not have UTI. The previous validation studies (see Chapters 1 and 2) have shown that dipsticks and clinical scoring algorithms can potentially help to modestly improve the precision of diagnosis by improving the PPVs;42 however, if clinicians are to use dipsticks they need to have strategies to deal with the poor NPVs. We are not aware of any trial that has evaluated dipstick or clinical management algorithms in comparison with the realistic alternatives such as empirical antibiotic treatment, empirical delayed prescribing and prescribing according to MSU results. Previous studies using empirical delayed antibiotics in respiratory infections have resulted in good symptom control, less belief in antibiotics and reduced reconsulations. 34,38,44

Objective

The objective of this study was to compare the effectiveness of management using dipstick or clinical algorithms with the effectiveness of alternative management strategies (empirical antibiotic treatment, delayed prescribing and targeted prescribing based on MSU results).

Method

The study was supervised by a trial steering committee that included a patient representative and which was under the chairmanship of Professor David Mant. The study took place in general practices in south-west England. Patients were recruited between June 2003 and May 2005. The target group of patients was non-pregnant women presenting with a suspected uncomplicated UTI. This group was chosen as it is the group presenting most frequently with suspected UTI in primary care and also the group for whom antibiotic use is not mandatory.

Randomisation

Patients were randomised within the consultation to one of five management groups: empirical antibiotic treatment (immediate antibiotics); empirical delayed antibiotics (patients were asked to wait 48 hours but could use antibiotics at their discretion); antibiotic targeted by symptom score (two or more of urine cloudy, urine offensive smell, moderately severe dysuria or nocturia); antibiotics targeted by dipstick algorithm (nitrites or leucocytes and a trace of blood); or antibiotics targeted by MSU results (symptomatic treatment until MSU results available) (Figure 1 and see Appendix 3 for more details). Randomisation using random number tables was in blocks to balance group numbers. Once consented, patients were allocated to a management group by the opening of a sealed opaque numbered envelope containing the instruction sheets for one of the five management groups. Sealed envelopes were used to facilitate randomisation and the implementation of this complex study – to ensure that only the sheets that the clinician needed were there. The potential to undermine randomisation was minimised by careful attention to maximising equipoise when presenting the study to clinicians, and by emphasising that women in all groups had access to antibiotics at their request. Sequential envelope use was also audited during the study to ensure integrity of randomisation.

Analysis

We assessed the impact of the management strategies using multiple regression, mutually controlling for all interventions. We used negative binomial regression for duration of symptoms (because of overdispersion of the data), multiple linear regression for the severity of symptoms, logistic regression for antibiotic use and repeat consultations, and Cox regression for time to first reconsultation. Our primary assessment was of the overall significance of each intervention factor, using the LR test for factors when there were multiple levels (e.g. five basic groups) and t-tests otherwise. We report the estimates of differences compared with the control group for each factor with the 95% CIs (i.e. in the case of the antibiotic management factor, the control group was immediate antibiotics, and for the other factors the control groups were no leaflet, no advice to use fruit juice and no advice to use bicarbonate). In a previous observational cohort, the exploratory factor analysis of the severity of symptoms demonstrated two groups of symptoms: these were increased day frequency, increased night frequency and urgency and dysuria (a ‘frequency’ group of symptoms; Cronbach’s alpha 0.77); and abdominal pain, restricted activities and feeling unwell (‘unwell’ group of symptoms; Cronbach’s alpha 0.80); therefore we analysed these two sets of symptoms separately.

Results

As might be expected with the randomisation method, numbers between groups differed, but there was no evidence of subversion of randomisation – there was no alteration in the order of envelope use and there were no significant differences by management group for the key baseline variables of severity of symptoms reported before seeing the doctor, the number of somatic symptoms reported48 and past cystitis (all of which were important confounders of outcome in previous studies) (Table 17). For the self-help advice groups there were some differences between groups (Table 18) but either these did not predict outcome (education, medical problems) or when outcome was predicted by the variable (particularly somatic symptoms – the Somatic Symptom Inventory) the estimates of outcomes in randomised groups were unaffected. We were able to document symptom severity and duration in 277 women (90%).

There were differences between groups in the number of patients for whom clinicians reported sending an MSU to the laboratory at the index consultation [immediate antibiotics 23% (15/66), MSU 89% (48/54), dipstick 36% (21/58), symptom score 33% (23/69), delayed antibiotics 15% (9/62); χ² = 81, p < 0.001]. There were also differences between groups in the number of patients for whom dipstick results were documented [immediate antibiotics 50% (33/66), MSU 52% (28/54), dipstick 95% (55/58), symptom score 55% (38/69), delayed antibiotics 29% (18/62); χ² = 55, p < 0.001]. Whether or not a doctor sent an MSU or documented dipstick results at the first consultation did not alter the effect of randomisation group on any outcome (i.e. including these variables in the models did not alter the estimates). The review and discussion of cases in which dipstick documentation and MSUs ordered were not prompted by the advice sheets (for 38 consecutive patients) made it clear that initial management had probably not been subverted. The main reasons highlighted were patient expectation; professional perceptions about the need for adequate documentation (dipsticks being regarded as ‘useful’ even if management was not based on them); and occasionally clinical reasons (e.g. a higher risk of complications was expected; a more definite initial diagnosis was required).

Discussion

This study is one of the few to document prospectively the outcomes of different initial management strategies of antibiotic use for suspected UTI.

Conclusion

Patients who delay by more than 48 hours while waiting for MSU results are likely to have much poorer symptom control. Immediate antibiotics targeted using dipsticks with a delayed prescription as backup or an empirical delayed prescription achieve similar symptom control to empirical antibiotics and help reduce antibiotic use.

Background

There is very little data available on the cost-effectiveness of different strategies for managing UTI. A previous decision analysis concluded that empirical antibiotic treatment was likely to be the most cost-effective strategy7 but this study had no direct evidence from randomised controlled trials on the likely estimates of costs and benefits of different management strategies.

In this chapter we report the results of a cost-effectiveness analysis carried out alongside the clinical trial.

Methods

The initial aim of the economics component of this research was to estimate the resource usage associated with the five strategies in the randomised controlled trial. However, as participants recorded the number of days of moderate/severe symptoms in the trial we were able to perform a cost-effectiveness analysis of cost per day of moderate/severe symptoms avoided. This information was obtained from participants’ completed diaries, up to a maximum of 14 days after recruitment.

We estimated costs from an NHS perspective. These comprised the cost of the recruitment visit to the GP, including any MSUs and dipstick tests carried out, and the cost of antibiotic prescribing at this visit. As it is possible for the care received in the recruitment visit to have ‘knock-on’ effects on subsequent use of services for UTIs, we also estimated the cost of care in a follow-up period. The follow-up periods used were the month and the year following recruitment into the study. As far as it was possible to identify, all costs measured were related only to the treatment of UTIs. All costs were estimated for the year 2005/6 and were in UK pounds sterling.

For the recruitment visit we obtained data from participating GPs. This included data on the length of time taken for the consultation. The time taken was costed using unit cost figures published by the Personal Social Services Research Unit (PSSRU) at the University of Canterbury. 50 In total, 39/309 cases had missing data for length of time taken for consultation. These data were imputed using a regression method with study group as an explanatory variable (SPSS version 14). This was checked against the original data to ensure that the means and standard errors of the estimated time in consultation for the imputed variables were equivalent to those of the original variable (means were within 1% in all cases). The costs of MSU and dipstick tests in the randomised trial were based on whether the GP or laboratory reported an MSU or whether a dipstick was carried out. The cost of the MSU was assumed to be the laboratory cost plus any consumables used. These were obtained from the finance department of the local NHS Trust. The time taken to perform the test would have been calculated as part of the time taken in the recruitment visit and so would already have been costed. Data were available on whether the study participant had antibiotics dispensed after the recruitment consultation. Again, considerable data were missing for this variable (41/309 cases), and so these missing data were imputed using the methods described above. For costing purposes we assumed that antibiotics were prescribed according to protocol, i.e. trimethoprim. For this, a cost was obtained from the British National Formulary. 51

For the follow-up period, data were obtained directly from GP notes. Two periods of follow-up were used in the costing study: 1 month and 1 year after recruitment. Longer periods of follow-up were available from the data but it was not felt that the strategy employed at the recruitment visit would have had an effect that persisted for more than 1 year. All consultations with the GP were costed using an estimated cost per visit obtained from the PSSRU unit costs. 50 This was based on a standard 10-minute consultation. MSUs performed in reconsultations were recorded and these were costed using the methods described earlier. Also recorded were antibiotics used. Finally, data were obtained on referrals to secondary care in the follow-up period. Referrals were excluded if they were unlikely to be attributable to UTIs; this was carried out in consultation with a clinical expert blind to group (PL). Referrals were included if there was evidence in the case notes that they had in fact taken place and they were costed using NHS reference costs. 52

Analysis

The data were analysed using Microsoft Excel and SPSS version 14. CIs were estimated using SPSS. Although there were 309 participants in the study, follow-up resource use data were not available for all. The cost analysis reported here was performed on participants for whom follow-up data were available – this comprised 283 individuals. To test the robustness of estimates obtained from the analysis we also estimated 95% percentiles using 1000 bootstrap samples. 53,54 This bootstrapping procedure was also used to estimate both cost-effectiveness and cost-effectiveness acceptability curves (CEACs) for the cost per day of moderate/severe symptom avoided. CEACs show the varying probability that an intervention is cost-effective as the value placed upon the outcome of interest is varied.

Results

Table 21 shows the resources used by the participants in the five study groups. For the recruitment visit there appear to be differences in the numbers taking antibiotics by group. There is little variation in resource use between groups at the 1-month follow-up; however, as would be expected, there is more variation at the 1-year follow-up as these events are likely to have a more tenuous relationship with initial randomisation group.

These resource use values were used to estimate the costs of treatment by randomisation group. These values are given in Table 22. It can be seen that the total costs for 1 month’s follow-up are similar between all five groups. Costs ranged from £30.70 to £37.10. The majority of these costs were attributed to the recruitment consultation, as there were few reconsultations in this period. For total costs for the 1-month follow-up there was a statistically significant difference between the MSU group and the immediate antibiotics, symptom score and delayed antibiotics groups. There were no statistically significant differences between any of the groups for the 1-year follow-up; these differences were examined using t-tests. To test the robustness of these results we also estimated bootstrapped confidence intervals. 53,54 In all cases these were extremely close to those generated using parametric methods.

We examined effectiveness in terms of the number of days of moderate/severe symptoms and also the cost-effectiveness in terms of the cost per day of symptoms avoided. This was carried out on those cases for which there were completed data for both costs and also symptoms and hence uses a smaller sample than that used for costs. The samples used for the five groups were as follows: immediate antibiotics 56/58, MSU 46/52, dipstick 42/51, symptom score 60/64, delayed antibiotics 54/58. These estimates of cost-effectiveness are presented in Table 23. Strategies in this table are ranked by mean cost (for 1-month follow-up). The effectiveness estimates are included as negative values, as number of days of moderate/severe symptoms is a disbenefit, i.e. the less the better. Incremental costs and effects are given compared with the least costly strategy. Most strategies are dominated, which means that there is some other strategy that is both less costly and more effective. The least costly strategy is immediate antibiotics. Compared with this strategy the dipstick strategy generated additional symptom days avoided and a cost of £9.30 per additional symptom day avoided.

The problem with Table 23 is that it takes no account of uncertainty – one strategy could be dominated by another if its mean values wereslightly worse and there may be no statistically significant differences between the cost or the effectiveness estimates. To allow for this uncertainty we estimated CEACs for the strategies, which are shown in Figure 2. These show the probability that a given strategy is cost-effective as the value placed upon the unit of effect is varied. If one strategy is more costly and more effective than another strategy then the higher the value placed upon the unit of effect the more likely that strategy is to be cost-effective. For example, if the value placed upon the unit of effect is zero then the more expensive strategy can never be cost-effective. If a very high value is placed upon the measure of effectiveness then there is an increased chance that the value of the extra benefit produced exceeds the extra cost and hence the strategy will be cost-effective. We varied the value of a day of moderate/severe symptoms avoided from £0 to £100. The strategy most likely to be cost-effective varies with changes in the value of a symptom day avoided. If a symptom day avoided is given a low value, i.e. less than approximately £10, then immediate antibiotics is likely to be the most cost-effective strategy. For values over £10, the dipstick strategy becomes the most likely to be cost-effective. Because of the uncertainty present, we can never be more than approximately 70% certain that the dipstick strategy is the most cost-effective.

Discussion

The results presented here suggest that all strategies have similar resource implications. The MSU strategy was statistically significantly more expensive than the immediate antibiotics strategy only at 1-month follow-up. There were no significant differences at the 1-year follow-up. It may be the case that if the sample sizes were larger there would be more statistically significant differences but the absolute magnitude of these are likely to be comparatively small. This is expected as the tests used in this study are low cost and routine and would be expected to make only small changes to the amount of time GPs would spend in providing care for UTI. There is therefore likely to be no strong reason to prefer any particular strategy on the basis of costs.

Regarding cost, a uniform length of follow-up was used in the economic evaluation to be able to compare each individual on a like-for-like basis. There were varying lengths of total follow-up time used in this study; this depended on when individuals were recruited, as those recruited early would tend to be followed up for longer. Using a set follow-up time would ensure that any differences in costs were not due to differences in follow-up. The fact that there were no differences in mean costs at the 1-year follow-up suggested that 1 month of follow-up was probably sufficient to detect any differences in costs. For the cost-effectiveness analysis we only present costs for the 1-month follow-up as we only have an outcome measure that covers the 14 days after recruitment.

The cost-effectiveness analysis shown here presents estimates of the cost per symptom day avoided. Extreme caution needs to be exercised here in the interpretation of these results because of the effectiveness data underlying them. For the cost-effectiveness results to be credible requires that the effectiveness results also be credible. Although the dipstick group had slightly better results than the MSU group for symptoms, the question is whether we sensibly rely on this data? The data for improvement in moderately severe symptoms were not significant. Supporting a probable improvement in the dipstick group is the fact that the severity of symptoms was also less in the dipstick group. Is it plausible that the dipstick group would have better results than the immediate antibiotics group? This is a little difficult to understand as the immediate antibiotics group should be giving all those with infection antibiotic cover, whereas the dipstick group will only imperfectly target such people. Perhaps the possible improvement in the dipstick group should not be dismissed too lightly – it is possible that patients’ symptom management is helped by the security of feeling that they know from dipsticks whether or not they have an infection.

The effectiveness measure used in this analysis is cost per day of moderate/severe symptom avoided. This presents a problem of interpretation as it requires an understanding of the value of a symptom day avoided and how much the NHS should be prepared to spend to achieve this. Our analysis suggests that symptom days can be avoided at an approximate cost of £10 per symptom day. A judgement would therefore need to be made on whether the value of avoiding days of moderate/severe symptoms would exceed this.

It should be noted that some potentially important factors are not included in this analysis. We take no account of productivity factors, i.e. avoiding symptom days may mean that individuals need less time off work. This would mean that the interventions may be more cost-effective than indicated here as avoiding symptoms would also incur less costs in terms of lost productivity. In addition, the current analysis does not attempt to quantify any benefits associated with reducing the use of antibiotics. This is a potentially important omission and would mean that interventions that were able to reduce the use of antibiotics would be undervalued in this framework. 55 The current analysis supports in principle previous work suggesting that performing an initial MSU in all patients is not likely to be cost-effective in clinical practice. 55

Conclusion

Dipsticks are likely to be cost-effective if the value of saving a day of moderately bad symptoms is valued at £10 or more, but caution is required given the considerable uncertainty surrounding the estimates.

Introduction

Urinary tract infections are common conditions in primary care with one out of two women suffering at least one episode in their lifetime. 1,29 There is debate about the self-limiting nature of UTIs and the value of antibiotic medication. 28 For respiratory infections it is clear that the issue of patient expectation for antibiotic medication shapes prescribing behaviour for many but not all doctors;56,57 however, the research evidence provides mixed messages about the level of patient expectation for antibiotic medication. Recent evidence suggests that doctors may in fact overestimate patients’ expectations for medication;58,59 however, little is known about women’s experiences of UTI and their views on taking antibiotic medication.

Understanding patients’ experiences, their journey to the doctors, why they seek medical help and their expectations when they seek such help is important. As Calnan60 explains, ‘patients’ specific reasons (and experiences) will have an influence on the way they evaluate the care that they receive’. More broadly, as Zola61 highlighted over 30 years ago: ‘The very labelling and definition of a bodily state as a symptom as well as the decision to do something about it is in itself part of a social process’ and understanding this process is critical to our understanding ‘the treatment and control of illness’.

This chapter describes a qualitative interview study, nested in our larger randomised controlled trial. Interviews explored patients’ views on UTI and the acceptability, or otherwise, of being asked to wait to take antibiotic medication. Information gathered contributes to our broader goal of building a coherent framework of understanding about UTI and its best management. These qualitative data help to indicate how future service interventions, such as the use of backup antibiotic strategies, may be organised to meet the needs of the consumers of such services.

Methods

Analysis

Drawing on the principles of analytic induction, thematic analysis was an iterative process. 62 Manual coding was used throughout and this began with initial familiarisation with the data. Vertical and horizontal familiarisation initially involved annotating transcripts with ‘a priori’ codes, based on the original research aims and topics covered by the interview guide. Next, summary cards were made for each interview on which we ‘extracted’ and ‘summarised’ key annotations/codes, our overall impressions and some verbatim quotations. 63 This ordering of data facilitated the later identification of emerging issues raised by participants and recurrent patterns, and permitted comparisons with concepts present in the literature.

Following initial coding, further reading and rereading of the transcripts dictated slight modifications to the thematic framework to manage contradictions and nuances in the data. Following the comparative method, which involves seeking out ‘deviant cases’,62 we aimed to ensure that all observations could be properly accounted for and that key themes were not prematurely formed. We tested the integrity of our observations by performing ‘crude counts’ of key observations to test their frequency. 62 Throughout the chapter we draw on a selection of exemplary fragments from the 20 transcripts to illustrate key themes. Saturation of themes had occurred in the 20 interviews.

Representation of thematic analysis can result in the decontextualisation of speakers’ words, which may fragment or misrepresent the intended meaning as they appeared in the original sequential narrative. Therefore, care was taken to analyse the participants’ words in the broader context of the surrounding utterances (vertical analysis) to ensure a fair interpretation of the meaning of the fragments reproduced in this chapter.

Results

In total, 33 women were approached to take part in the interview study: 27 agreed and 21 were interviewed (we had reached saturation). Reasons for refusal included only being available in the late evening, when the researchers were not available, and being too busy at work. Following one tape failure we produced 20 audio recordings. As is routine in qualitative work, the sample size was never intended to permit comparisons of attitudes and understandings according to participants’ face-sheet characteristics, such as age, occupation and so forth, although we did anticipate that there might be some differences between women with a previous history of UTI and those without.

Seven women were in the symptom score group, nine in the empirical delayed antibiotics group and two each in the symptom score and MSU groups. The characteristics of the women participating in the qualitative study were similar to those of the overall trial cohort: 65% versus 73% married, 88% versus 85% past cystitis, mean 3.00 versus 2.6 number of medical problems, 17.6 versus 17.6 age leaving education, mean 3.5 versus 3.5 severity of frequency symptoms at baseline respectively.

The findings are divided into two broad parts:

• part one: experiences of UTI and health-seeking behaviour

• part two: perspectives on and understanding of UTI and its treatment.

Included within each of these two broad parts are several subsidiary themes. Part one illuminates the different stages in participants’ prediagnostic illness trajectory – from first noticing symptoms to going to see the doctor. Part two moves on to participants’ reported beliefs about UTI, including their views on the use of a backup antibiotic management strategy.

Discussion

Conclusion

If women are asked to delay taking antibiotics, great care is needed in both acknowledging the triggers to consult and particular worries and explaining the rationale for not using antibiotics immediately.
