Potential Conflict of Interest and Bias in the RACGP's Smoking Cessation Guidelines: Are GPs Provided with the Best Advice on Smoking Cessation for their Patients?

The primary care experience of adults with chronic obstructive pulmonary disease (COPD). An interpretative phenomenological inquiry

BACKGROUND

Studies of the lived experience of chronic obstructive pulmonary disease (COPD) reveal a number of challenges patients face when interacting with healthcare providers that may be exacerbated by unwillingness or inability to quit smoking. However, none have explored, in-depth, primary care experiences among patients with COPD in community healthcare settings.

AIMS/ OBJECTIVE

The study investigated healthcare experiences of patients living independently in the community with COPD who smoked or had recently quit (at most within the last 5 years), seeking care in primary care settings.

METHOD

An Interpretative Phenomenological Analysis (IPA) involving thirteen participants purposively recruited from social media posts in COPD and carer support groups, general community groups, community noticeboards and paid adverts on social media. In-depth interviews were held between February and April 2022 by phone or Zoom™ and explored patient experience of primary care, focusing on how smoking patterns, addiction and stigma impact upon and shape these experiences.

RESULTS

Participants were aged between 45 to 75 years. Nine were female and two thirds were current smokers. Problematic experiences including time-constrained consultations, having to self-advocate for care "…go digging myself and then go and see him and say, can we do this, can we do that type of thing?" and guilt about smoking were common. Positive care experiences described non-judgemental interpersonal interactions with doctors, timely referral, proactive care and trust "I have an actual great trust for my GP… they're awesome, they'll look after you". Participants described how their care experience shifted as primary care adapted care delivery during COVID-19.

CONCLUSIONS

Pro-active, empathetic care from general practitioners is desired from patients living with COPD. Stigma and fear of judgement was an important underlying driver of negative care experiences contributing to delayed help seeking from general practitioners.

Conflicts of interest in clinical guidelines, advisory committee reports, opinion pieces, and narrative reviews: associations with recommendations

BACKGROUND

Treatment and diagnostic recommendations are often made in clinical guidelines, reports from advisory committee meetings, opinion pieces such as editorials, and narrative reviews. Quite often, the authors or members of advisory committees have industry ties or particular specialty interests which may impact on which interventions are recommended. Similarly, clinical guidelines and narrative reviews may be funded by industry sources resulting in conflicts of interest.

OBJECTIVES

To investigate to what degree financial and non-financial conflicts of interest are associated with favourable recommendations in clinical guidelines, advisory committee reports, opinion pieces, and narrative reviews.

SEARCH METHODS

We searched PubMed, Embase, and the Cochrane Methodology Register for studies published up to February 2020. We also searched reference lists of included studies, Web of Science for studies citing the included studies, and grey literature sources.

SELECTION CRITERIA

We included studies comparing the association between conflicts of interest and favourable recommendations of drugs or devices (e.g. recommending a particular drug) in clinical guidelines, advisory committee reports, opinion pieces, or narrative reviews.

DATA COLLECTION AND ANALYSIS

Two review authors independently included studies, extracted data, and assessed risk of bias. When a meta-analysis was considered meaningful to synthesise our findings, we used random-effects models to estimate risk ratios (RRs) with 95% confidence intervals (CIs), with RR > 1 indicating that documents (e.g. clinical guidelines) with conflicts of interest more often had favourable recommendations. We analysed associations for financial and non-financial conflicts of interest separately, and analysed the four types of documents both separately (pre-planned analyses) and combined (post hoc analysis).

MAIN RESULTS

We included 21 studies analysing 106 clinical guidelines, 1809 advisory committee reports, 340 opinion pieces, and 497 narrative reviews. We received unpublished data from 11 studies; eight full data sets and three summary data sets. Fifteen studies had a risk of confounding, as they compared documents that may differ in other aspects than conflicts of interest (e.g. documents on different drugs used for different populations). The associations between financial conflicts of interest and favourable recommendations were: clinical guidelines, RR: 1.26, 95% CI: 0.93 to 1.69 (four studies of 86 clinical guidelines); advisory committee reports, RR: 1.20, 95% CI: 0.99 to 1.45 (four studies of 629 advisory committee reports); opinion pieces, RR: 2.62, 95% CI: 0.91 to 7.55 (four studies of 284 opinion pieces); and narrative reviews, RR: 1.20, 95% CI: 0.97 to 1.49 (four studies of 457 narrative reviews). An analysis combining all four document types supported these findings (RR: 1.26, 95% CI: 1.09 to 1.44). One study investigating specialty interests found that the association between including radiologist guideline authors and recommending routine breast cancer screening was RR: 2.10, 95% CI: 0.92 to 4.77 (12 clinical guidelines).

AUTHORS' CONCLUSIONS

We interpret our findings to indicate that financial conflicts of interest are associated with favourable recommendations of drugs and devices in clinical guidelines, advisory committee reports, opinion pieces, and narrative reviews. However, we also stress risk of confounding in the included studies and the statistical imprecision of individual analyses of each document type. It is not certain whether non-financial conflicts of interest impact on recommendations.

Relationship Between Declarations of Conflict of Interests and Reporting Positive Outcomes in Iranian Dental Journals

Conflict of interests is a situation when someone is in need of other people's trust on one the hand and has personal or general interests on the other hand, resulting in conflict with the given responsibility. In this research work, an attempt was made to find the relation between declarations of conflict of interests and reporting positive outcomes in the dental journals in Iran (2000-2016). In this analytical/cross-sectional study, first Health and Biomedical Information was searched and all the Persian and English dental journals published in Iran were collected. Then, all the papers published in the journals from December 2000 to December 2016 were collected and categorized in terms of the year of publication, author or authors' affiliations, Persian and English journal, type of the substance or the drug used (including the manufacturing company), declarations of conflict of interests and the positive or negative conclusion of the report. Data were analyzed with the Fisher's exact test and Chi squared test, using the program SPSS 18. In numerical analysis, the significance was set at P < 0.05. Seventeen dental journals in Persian and English were analyzed: 10 in English and 7 in Persian. Reviewing these studies showed that of 1021 articles in Persian, in 128 cases there was no mention of a declaration of conflict of interests and in 11 cases, the COI had been stated. In addition, from 1220 articles in English, in 825 cases there was no mention of declarations of conflict of interests and in 45 cases, the declarations of COI had been mentioned. There was no significant relation between the COI and 'no' COI and the reporting of positive outcomes in papers in Iranian dental journals in terms of the journal type, year of publication and the journals' guarantee form (P = 0.25, P = 0.41 and P = 0.09). A total of 83% of studies with declarations of COI had one positive outcome, with a significant relationship in this field; however, in 73% of studies with no COI, there was one positive outcome, too. In general, the society expects that doctors would not consider any incentives except the health of the patients in the efforts made by them. The severity of the consequences of COI is of higher value when the patients' health is endangered due to it. In addition, COI might change the attitude and approach of other doctors and peers.

Evidence Regarding the Impact of Conflicts of Interest on Environmental and Occupational Health Research

PURPOSE OF REVIEW

This review describes published literature providing evidence for financial conflicts of interest in environmental and occupational health research. Secondary goals were to describe evidence that (a) utilized quantitative methods to evaluate the association of conflicts with study outcomes, and (b) assessed undisclosed as well as disclosed conflicts of interest.

RECENT FINDINGS

Forty-three studies were identified which contained descriptions of the impact of financial conflicts of interest on research results; 11 of these conducted quantitative analyses to demonstrate these relationships. All 11 articles which quantified associations identified significant associations of the presence of financial conflicts of interest with study findings. In studies which measured undisclosed conflicts, these comprised a substantial proportion of all conflicts. Suggestions for improving understanding and interpretation of research results are presented.
