Internet search method

Initially, the 50 websites most frequently returned using each of the searches were recorded. This number was chosen as most lay searchers do not look beyond the first page of results and concordance between common search engines is approximately 50% [17, 19]. Website links were excluded if they did not appear to contain any information relevant to the key terms entered, in either the link itself or the surrounding text (for example veterinary, advertising or dictionary websites). The search process is outlined in Figure 1.

Criteria for evaluating websites

Each website was accessed between March 2012 and April 2013 by two reviewers independently and data collected by accessing the relevant pages of the website. Once accessed, all websites were included whether felt to be relevant to birth after previous caesarean section or not.

The data collected for each website included ten generally agreed key characteristics to help assess quality and relevance of health information on the internet: Authority of source; Purpose of website; Date of last update; Country of origin; Intended audience; Provision of disclaimer; Funding source; Contact details; References; Links [13, 14, 16, 17]. If websites mentioned any of the advantages and disadvantages of VBAC or ERCS in the RCOG patient information leaflet on birth after previous caesarean, these were recorded and scored [8]. If additional advantages or disadvantages of either mode of delivery were mentioned on the website this was also recorded and categorised into ‘supporting VBAC’ or ‘supporting ERCS’, but not included in the score.

Analytic methods

Poisson regression analysis was used to assess the effect of website quality characteristics on scores achieved in support of each mode of delivery. To adjust for over-dispersion, the Pearson chi-square method was used to estimate the scale parameter. As an extra check, we also fitted a negative binomial model and used the Lagrange multiplier test to test whether the ancillary parameter equalled zero. A non-significant result meant that over-dispersion was not a concern. The website characteristics which were considered included: authority of source (‘included health professional’ or ‘did not include health professional’); country of origin (‘UK’, ‘US’ or ‘other’); intended audience (‘included the general public’ or ‘included health professionals’) and funding source (‘commercial’, ‘government’ or ‘other’). These characteristics were selected as they were considered likely to influence whether or not women would consult a particular website. For example, some women might seek websites where information is relevant to their country (and therefore healthcare system), while others are more trusting of government (e.g. NHS) websites. Statistical analyses were performed using Statistical Package for Social Scientists Version 18.

Pilot search

The pilot search produced quality scores ranging from 8 to 10 out of a possible 10, with seven sites scoring for all 10 parameters. The content scoring revealed that each piece of information suggested in the RCOG document featured on at least two websites and at least two pieces of information featured on all ten websites. The search strategy was not altered following the pilot search. The pilot results were not included in the final set of results.

Main data

Search results

A total of 950 web links were returned using the search terms outlined in Table 1. After excluding duplicate web links, a total of 298 individual websites were counted. Of these, 48 were counted five times or more and were included for analysis (Table 3). Exactly 50 websites could not be distinguished using the chosen counting process, as 13 sites appeared four times overall. The most popular website appeared 27 times across the various searches, reflecting the repetitive nature of links appearing on any one list of search results.

Quality assessment of top websites

The number of websites displaying the various website ‘quality’ characteristics is illustrated in Figure 2. Essentially, the majority of websites were clearly accredited by health professionals (n = 37), with most aimed at providing information to prospective parents (n = 38). All websites had an available feedback mechanism and displayed country of source. Most websites were sourced from the USA (n = 26), with the main funding source overall being advertising (n = 20). For these ‘quality’ characteristics, each website was given a score out of 10. Less than one quarter (n = 10) of websites scored 10, but all websites scored 5 or more.

Comparison of website clinical data to gold standard

The number of websites demonstrating individual criteria supporting either VBAC or ERCS as outlined in the RCOG patient document was recorded (Table 2). The percentage score achieved in support of either VBAC or ERCS for each website was calculated (Figure 3). Only one of 48 websites mentioned 100% of points in favour of VBAC as mentioned in RCOG ‘gold standard’ patient information, with just two of 48 websites mentioning 100% of points in favour of ERCS. The most commonly addressed criterion was the increased risk of uterine scar rupture with VBAC (n = 45). Forty sites provided additional information in support of VBAC which not mentioned in the RCOG guidance. Most commonly cited examples included risks of wound infection (n = 21), haemorrhage (n = 18) and maternal surgical injury (n = 14) with ERCS. Twenty seven sites provided additional information in support of ERCS. Most commonly cited examples included the risk of incontinence (n = 7) and traumatic perineal injury (n = 8) following VBAC. Many of these ‘additional’ information points collected were discordant with best available evidence [2, 3].

Of 24 possible pieces of information provided in support of either ERCS or VBAC, the mean number provided by all 48 websites assessed was 10.4 (SD 4.6). As a percentage of the total available points in support of VBAC, the overall mean score was 42.4% (SD 23.8). As a percentage of the total available points in support of ERCS, the overall mean score was 44.8% (SD 25.0). This difference in means was not statistically significant (p = 0.57). Of the five most frequently returned websites, the mean score in support of VBAC was 40.0% (SD 13.9) and in support of ERCS was 66.0% (SD 20.7). Uterine scar rupture (91.7%) with VBAC and increasing complications with each CS (72.9%) were the most frequently mentioned criteria by websites overall, with few websites mentioning that ERCS was a longer (8.3%), more difficult procedure (12.5%).

Website characteristics as predictor of content scores

The authority of source, intended audience and funder of the websites did not have any association with the number of supportive criteria presented for either VBAC or ERCS. However, country of origin appeared to impact ERCS total scores, with UK websites reporting 88% higher scores (95% CI 24–186) than USA websites (Table 4). Country of origin had no association with the score for VBAC. For both models the Lagrange multiplier test was not significant meaning that over-dispersion may not be a concern.

Website characteristic	VBAC (rate ratio with 95% CI)	ERCS (rate ratio with 95% CI)
Funder (versus Commercial)
Government	1.46 (0.87-2.45)	0.91 (0.55-1.51)
Other	0.89 (0.60-1.32)	1.02 (0.71 -1.49)
Country of origin (versus US)
UK	0.96 (0.58-1.57)	1.88 (1.24-2.86)
Other	1.13 (0.74-1.73)	1.34 (0.90-2.00)
Authority of source (versus health professional)
Other	1.21 (0.81-1.80)	1.09 (0.73-1.63)
Intended audience (versus General public)
Including health professional	0.74 (0.47-1.18)	1.17 (0.78-1.75)

Note: Each column represents one Poisson regression model adjusted for all four website characteristics.

Main findings

This study has revealed that the content of readily accessed websites with information on birth options after CS reflect that contained in the RCOG patient information document ‘Birth after previous caesarean; information for you’ to a variable extent. At the extreme ends of the spectrum; from 24 key pieces of information which the RCOG recommend women are made aware of; the risk of a long operation with ERCS is discussed in only four of 48 websites assessed while uterine rupture is discussed on 45 of the 48. Less than half of the facts in support of either mode of delivery were featured on all 48 websites. Only country of origin was associated with the number of criteria supportive of ERCS with the UK reporting more supportive criterion than the US. The five most frequently returned websites contained two thirds of the facts supportive of ERCS, and less than half of those supportive of VBAC.

Strengths and limitations

The initial website searches performed on Google™ were not limited to those in the UK as it was felt unlikely the lay searcher would perform this function. As a result, more than half of the top websites originated from the USA and only 11 from the UK. For this reason, website information could have been skewed towards guidance on birth after caesarean which has been published internationally. On the other hand, no significant differences have been found between the RCOG or ACOG guidelines on birth after previous caesarean [3, 4, 20].

Another potential limitation of this internet survey is that the criteria used for the evaluation of website quality are not formally validated and the data scoring method is somewhat arbitrary. However, no consensus guideline for the evaluation of internet information exists. We therefore used criteria which have been cited as commonly used principles for this purpose [13–16]. In our analyses we have regarded all criteria as carrying equal weight in terms of importance. We cannot assume however that one website provides more reliable information than another, without first judging the individual importance of each criterion in clinical practice. This is especially important considering women are known to favour the delivery mode with least neonatal risk at the possible expense of increased maternal risk [21, 22]. Therefore websites may have scored highly despite failing to mention for example; the risk of increased neonatal mortality with VBAC, or increased risk of infant respiratory distress with ERCS.

Throughout this study, the RCOG guidelines and their supplementary patient information have been regarded as ‘gold standard’ [3, 8], with website information being scored against this. However it must be noted that the RCOG guidance has been based on best available evidence in the form of retrospective cohort studies and not randomised controlled trials. Additionally, the document was published in 2008, so there is potential for more recent research to supersede the document content. Despite this, it is the most comprehensive guidance available to date on which to base our findings, but results of future studies should prompt review of this internet survey.

It should also be noted that health information on the internet is a rapidly evolving field and the absolute results from this study will quickly become superseded by updated published guidance (e.g. NICE CG132 ‘Caesarean section’ [6]) and internet information (e.g. http://sdm.rightcare.nhs.uk/pda/birth-options-after-previous-caesarean/introduction/). In addition, there are websites available which provide good quality information on birth after caesarean that were missed using our chosen search method. Whilst acknowledging the unavoidability of such limitations, this study serves to provide a ‘snapshot’ of the nature and quality of internet information available to and accessed by women on this topic.

Interpretation

These results are amongst the first regarding the reliability of internet information on birth after previous caesarean section. Despite any potential drawbacks, this study has demonstrated that internet information on this topic is highly variable in quality and in content. A large number of unregulated and unaccountable sources are providing potentially incomplete and somewhat misleading information. This is despite efforts to improve the quality of health information available on the internet [16]. On the other hand, some websites were deemed highly reliable and balanced when compared to official guidance. Considering that the general public are notably poor in interpreting the quality of internet information [17], obstetricians should be prepared to direct pregnant women towards appropriate advice on birth after previous caesarean section. This could be done when women present to the antenatal consultation, regardless of whether or not they already have a preconceived decision on delivery mode.

This study supports what is known from previous studies about health information on the internet, in that information can often be of poor quality and contain misleading content [19, 23–30]. However it should be noted that several websites accessed in this study actually scored favourably in relation to the ‘gold standard’ and appeared to convey high quality, reliable information (Table 3). In fact, the RCOG ‘gold standard’ patient information presented itself within the overall search results, in addition to NHS patient information leaflets which closely reflected RCOG guidance. It is reassuring that women have the opportunity to access the best quality information, but they may not necessarily have the ability to contextualise this amongst less reliable sources. It is of interest that websites from the UK featured more information supportive of repeat CS than those from other countries. This may relate to the majority of such websites being owned by national health services, who are accustomed to providing comprehensive patient information regarding treatment options which plays a role in reducing risk of litigation. As failed VBAC is a major source of litigation, it is possible that greater effort is made to ensure that information on its consequences, including scar rupture, and means of avoiding these through repeat CS, is widely available to patients.

The internet is known to be a substantial resource used by pregnant women for information throughout their pregnancy and is likely to be utilised by women researching birth after previous caesarean section [11, 12]. Our study confirms that a wealth of internet information exists on birth after previous caesarean section and has identified approximately three hundred different websites addressing this topic.

Interestingly none of our top web link results were ‘blog’ or ‘social networking’ style links even though these types of internet site are known to be accessed as a valuable means of support for pregnant women with previous caesarean section [22]. Perhaps this conveys that these ‘blog’ style websites lack generalisability since they are most often written, and even accessed, by highly educated, middle class American women [22]. Nevertheless ‘blog’ style websites have been found to strongly favour VBAC as the preferred birth mode, despite our results which show both modes of delivery after caesarean as equally supported on the most popular internet sites [22].

Research and clinical implications

The findings of this study will inform care providers of the completeness of information and the most supported mode of birth to which patients may be exposed within their own home. This will enable delivery of advice regarding use of the internet for such purposes and may influence the development of future strategies to educate women on risks and benefits of modes of delivery after caesarean section via the internet.

Although this study has highlighted the availability of potentially poor quality, misleading internet information, many websites identified provided a high standard of information and balanced account of the options available. Combining this with incomplete advice often given by physicians themselves in comparison to official guidance [31, 32], then perhaps an area for further investigation is whether some internet healthcare information sources are actually more informative, accurate and balanced than that provided by healthcare professionals.
