Background Chronic pain is a prevalent and burdensome problem within the Canadian health care system, where the gold standard treatment occurs at multidisciplinary pain facilities. Patient intake questionnaires (PIQs) are standard practice for obtaining health information, with many patients including free-text (e.g., writing in margins of questionnaires) on their PIQs.Aims This study aims to quantitatively examine whether and how patients who include free-text on PIQs differ from those who do not.Methods We retrospectively analyzed 367 PIQs at a Canadian pain facility in Winnipeg, Canada. Patients were categorized into free-text (i.e., any text response not required in responding to questions) or no free-text groups. Groups were compared on sociodemographics, pain, health care utilization, and depressive symptoms with independent samples t-tests and chi-square analyses.Results Patients with free-text compared to those without had more sources of pain (6.66 vs. 4.63), longer duration of pain (123.2 months vs. 68.1 months), and a greater proportion of past pain conditions (66.3% vs. 55.2%). Additionally, they had tried more treatments for their pain, had seen more specialists, had tried more past medications, were currently on more medications, and had undergone more tests. No differences were identified for depressive symptoms across groups.Conclusions This study is the first to examine patient and health-related correlates of free-text on PIQs at a Canadian pain facility. Results indicate that there are significant differences between groups on pain and health care utilization. Thus, patients using free-text may require additional supports and targeted interventions to improve patient–physician communication and patient outcomes.
There is growing recognition of illness-induced post-traumatic stress disorder (PTSD), defined by illness being the index trauma that induces PTSD symptoms. This is the first study to examine 1) the lifetime prevalence of illness-induced PTSD among military personnel and veterans, and its 2) sociodemographic, military, trauma, and physical health condition correlates.Participants completed the 2002 Canadian Community Health Survey-Mental Health and Well-being - Canadian Forces (N = 5155) and the 2018 Canadian Armed Forces Members and Veterans Mental Health Survey follow-up (n = 2941). A semi-structured clinical interview assessed PTSD, which we categorized as "illness-induced" or "other trauma-induced" PTSD based on the index trauma in those participating in both timepoints. To ensure representativeness of our study sample, we used baseline weights created by Statistics Canada to report weighted prevalence estimates and inferential statistics.The estimated lifetime prevalence of PTSD among the full sample was 22% and 1.5% had lifetime illness-induced PTSD. Among those with lifetime PTSD, the proportion of participants with illness-induced PTSD was 8.3% (91.7% met criteria for other trauma-induced PTSD). In an unadjusted model, the prevalence of illness-induced PTSD was greater for females (13.7%) than males (7.2%), and for those who were not deployed in both 2002 (5.7%) and 2018 (7.1%; unadjusted odds ratio (OR) range: 2.05-3.72). In a multinomial model adjusting for sociodemographic and military characteristics, compared to those with other trauma-induced PTSD, those with illness-induced PTSD had elevated rates of PTSD persistence (24.1% vs. 11.9%; RRR = 6.06, 95% CI [1.21-30.25]) and lower rates of remission (7.8% vs. 19.9%).Results highlight differences between illness-induced PTSD and other trauma-induced PTSD, primarily the potential chronicity of this manifestation. This may have implications for assessment strategies and targeted interventions.
This chapter summarizes the current literature on post-traumatic stress disorder (PTSD) and chronic pain among military personnel in Canada, the United States, and the United Kingdom, including an overview of clinical features, prevalence, correlates, comorbidity, assessment, and intervention. PTSD and chronic pain are both prevalent among military populations and commonly co-occur; however, prevalence estimates tend to vary in the literature, according to type of assessment, timing of assessment, and subsample of interest. Both PTSD and chronic pain are independently associated with various adverse correlates such as psychiatric and physical health comorbidity, and research suggests there are poorer health and adverse psychosocial effects when these conditions co-occur. These findings highlight the importance of adequate prevention, screening, and interventions among this population.
BACKGROUND Clinically elevated preoperative distress and anxiety are common among patients undergoing cancer surgery. Preoperative interventions have been developed to mitigate this distress and anxiety but are inconsistent in efficacy and feasibility for broad implementation. OBJECTIVE This preliminary pilot study aims to assess the feasibility and utility of a newly developed virtual reality (VR) intervention to expose patients awaiting breast cancer surgery to the operating room environment and a simulation of anesthetic induction. METHODS Patients undergoing breast cancer surgery (N=7) were assigned to the VR intervention or control (treatment as usual) group and completed self-report measures of distress and anxiety before surgery, on the day of surgery, and after surgery (5 and 30 d postoperatively). Those in the intervention group trialed the VR simulation 1 to 2 weeks preoperatively and provided qualitative and quantitative feedback. We assessed the feasibility of recruitment capability and study design and evaluated participants’ impressions of the intervention using self-report rating scales and open-ended questions. We also descriptively examined distress and anxiety levels throughout the duration of the study. RESULTS Recruitment occurred between December 2021 and December 2022 and progressed slowly (rate: 1 participant/7 wk on average; some hesitancy because of stress and being overwhelmed). All participants who consented to participate completed the entire study. All participants were female and aged 56 (SD 10.56) years on average. In total, 57% (4/7) of the participants were assigned to the intervention group. On average, intervention participants spent 12 minutes engaged in the VR simulation. In general, the intervention was rated favorably (eg, clear information, enjoyable, and attractive presentation; mean<i><sub>% agreement</sub></i> 95.00-96.25, SD 4.79-10.00) and as helpful (mean<i><sub>% agreement</sub></i> 87.50, SD 25.00). Participants described the intervention as realistic (eg, “It was realistic to my past surgical experiences”), impacting their degree of preparedness and expectations for surgery (eg, “The sounds and sights and procedures give you a test run; they prepare you for the actual day”), and having a calming or relaxing effect (eg, “You feel more relaxed for the surgery”). CONCLUSIONS This preoperative VR intervention demonstrated preliminary feasibility among a sample of patients undergoing breast cancer surgery. Results and participant feedback will inform modifications to the VR intervention and the study design of a large-scale randomized controlled trial to examine the efficacy of this intervention.
