Diagnosing and managing prescription opioid use disorder in patients prescribed opioids for chronic pain in Australian general practice settings: a qualitative study using the theory of Planned Behaviour.

Chronic pain is a debilitating and common health issue. General Practitioners (GPs) often prescribe opioids to treat chronic pain, despite limited evidence of benefit and increasing evidence of harms, including prescription Opioid Use Disorder (pOUD). Australian GPs are worried about the harms of long-term opioids, but few are involved in the treatment of pOUD. There is little research on GPs' experiences diagnosing and managing pOUD in their chronic pain patients. This qualitative research used semi-structured interviews and a case study to investigate GPs' experiences through the lens of the Theory of Planned Behaviour (TPB). TPB describes three factors, an individual's perceived beliefs/attitudes, perceived social norms and perceived behavioural controls. Participants were interviewed via an online video conferencing platform. Interviews were transcribed verbatim and thematically analysed. Twenty-four GPs took part. Participants were aware of the complex presentations for chronic pain patients and concerned about long-term opioid use. Their approach was holistic, but they had limited understanding of pOUD diagnosis and suggested that pOUD had only one treatment: Opioid Agonist Treatment (OAT). Participants felt uncomfortable prescribing opioids and were fearful of difficult, conflictual conversations with patients about the possibility of pOUD. This led to avoidance and negative attitudes towards diagnosing pOUD. There were few positive social norms, few colleagues diagnosed or managed pOUD. Participants reported that their colleagues only offered positive support as this would allow them to avoid managing pOUD themselves, while patients and other staff were often unsupportive. Negative behavioural controls were common with low levels of knowledge, skill, professional supports, inadequate time and remuneration described by many participants. They felt OAT was not core general practice and required specialist management. This dichotomous approach was reflected in their views that the health system only supported treatment for chronic pain or pOUD, not both conditions. Negative beliefs, negative social norms and negative behavioural controls decreased individual behavioural intention for this group of GPs. Diagnosing and managing pOUD in chronic pain patients prescribed opioids was perceived as difficult and unsupported. Interventions to change behaviour must address negative perceptions in order to lead to more positive intentions to engage in the management of pOUD.

Qualitative insights into the opioid prescribing practices of Australian GP.

Over the last three decades, Australian opioid-prescribing rates and related morbidity and mortality have dramatically increased. Opioids are frequently prescribed by general practitioners (GPs) to manage chronic non-cancer pain, despite evidence-based recommendations from the Centre for Disease Control, National Institute for Health and Care Excellence and World Health Organization widely cautioning their use. Little is known about the factors influencing the opioid prescribing decisions of Australian GPs, especially when not evidence based. To explore the opioid prescribing knowledge, attitudes and practices of Australian GPs. Semi-structured interviews with 20 GPs recruited from the Monash University practice-based research network in metropolitan, southeastern Melbourne. Thematic analysis was used to identify emergent themes. Data were managed using QSR NVivo. Ethics approval was granted by Monash University. Three key themes emerged. GP attitudes towards opioid use for chronic pain varied by age of patient and goals for therapy. Use of opioids for elderly patients was positively perceived. GPs were reluctant to use opioids in younger patients due to fears of addiction and difficulty weaning. GPs felt obliged to prescribe opioids recommended by specialists, even if they believed the opioids were unsafe. This study identified and described the patient-centred nature of GP opioid prescribing decisions. Patient age and perceived age-related opioid harm were important factors influencing prescribing decisions. Future work should inform interventions that value GP autonomy while still encouraging a collaborative inter-speciality approach to managing chronic pain patients with opioids.

[Patterns of prescription of opioid analgesics in Hôtel-Dieu de France of Beyrouth].

Use of chronic opioid therapy has increased substantially over the past few years, even though opioid therapy is associated with potentially serious harms, including opioid-related adverse effects and outcomes. Prescription of opioids for chronic pain, particularly nonmalignant chronic pain, remains controversial. In the midst of this controversy, patterns of actual prescription and influences on these patterns are not well understood. This study aims to describe the frequency of prescription of opioid analgesics in a university hospital, the attitudes of doctors towards this category of drugs, and the follow-up modalities of patients taking these drugs. The study also explores the association between the practitioners' characteristics and the modalities of prescription. A survey was delivered to 112 doctors and surgeons in the hospital during the four months between August and December 2013 and it was returned by 55 (49.0%). The survey consists of three parts. The first part addresses the frequency and reluctance of doctors' prescription of opioids and other analgesics for acute and chronic pain. The second part studies the doctors' attitudes and concerns towards opioids. It explores the belief of the doctors in the efficacy of this category of drugs, their confidence in prescribing such medications and the eventual side effects they might worry about. The third part of the survey studies the modalities of evaluation prior to the prescription and the modalities of follow-up of the patients receiving a long-term opioid treatment. Overall, 76.4% of doctors reported they sometimes, frequently, or always, prescribe opioids, which, using the Wilcoxon test, proved to be a significantly lower frequency than for prescribing of minor analgesics or nonsteroidal anti-inflammatory drugs (NSAIDS). Similarly, 60.1% reported a reluctance to prescribe opioids for chronic nonmalignant pain, which was a significantly greater reluctance than for cancer pain. The age and sex of the participants were unrelated to prescribing, but those with specialty training and use of practice guidelines were more likely to prescribe opioids and were less reluctant to do so. A majority of practitioners felt that opioids are effective for the treatment of chronic nonmalignant pain and that they have the sufficient training to prescribe them adequately; however, they still worry about the long-term prescription of opioids, particularly fearing the psychological dependence this treatment might cause. Using a series of Spearman correlation tests, we found that practitioners who thought they were adequately trained and who believed in the efficacy of long-term opioid treatment were more likely to prescribe them but that the worries about side effects decreased the frequency of prescription. A significant proportion of practitioners do not evaluate addiction risk factors of patients before prescribing opioids. The results concerning the modalities of follow-up of prescription were very heterogeneous with 87% of practitioners not explaining and 65% not screening for adverse effects. We similarly found that the frequency of follow-up and the management of patients who were exhibiting signs of dependence were very diverse. The results of this study were compatible with those of other recent studies about opioid prescription. The doctors practicing in the university hospital Hôtel-Dieu de France de Beyrouth present comparable prescription patterns, independent of their personal or professional characteristics, and they are more confident in their prescription when professionally trained for it. However, they exhibit a notable heterogeneity in their attitudes towards opioids and in their modalities of evaluating patients receiving long-term treatment. These results suggest a need for additional training in the management of this category of drugs.
