Patients' views and experiences on the use and safety of directly acting oral anticoagulants: a qualitative study.

BACKGROUND: Direct oral anticoagulants (DOACs) are considered high-risk medications and used to prevent thromboembolic events and stroke. This study aimed to examine patients' views and experiences of DOACs use and factors that can promote safety associated with DOACs. METHODS: In-depth interviews were conducted with adult patients who had been prescribed DOACs, identified and invited by local collaborators in three different tertiary care hospitals in Saudi Arabia. A topic guide developed based on was used to inform the interview. Data were analysed thematically. RESULTS: Data saturation was achieved by the ninth participants. Three major themes were identified: (1) factors affecting DOAC's safety from the patients view; (2) barriers to adherence to DOACs and (3) strategies to promote the safety of DOACs. Lack of knowledge of DOACs, using inappropriate sources of information, lack of communication with HCPs, difficulty in having access to DOACs and lack of monitoring were the main factors affecting the safe use of DOACs. Unavailability of the drugs and difficulty in timely getting to hospitals affected adherence. Patients acknowledged difficulties communicating with healthcare professionals, timely access to anticoagulation clinics and in obtaining their DOACs on time. CONCLUSIONS: There is a need to develop and evaluate theory-based interventions to promote patient knowledge, understanding and shared decision-making to optimise DOACs use and improve their safety.

The effect of anesthesia on the magnitude of the postoperative systemic inflammatory response in patients undergoing elective surgery for colorectal cancer in the context of an enhanced recovery pathway: A prospective cohort study.

ABSTRACT: There are reports that the use of regional anesthesia (RA) may be associated with better perioperative surgical stress response in cancer patients compared with general anesthetics (GA). However, the role of anesthesia on the magnitude of the postoperative systemic inflammatory response (SIR) in colorectal cancer patients, within an enhanced recovery pathway (ERP), is not clear.The aim of the present study was to examine the effect of anesthesia, within an enhanced recovery pathway, on the magnitude of the postoperative SIR in patients undergoing elective surgery for colorectal cancer.Database of 507 patients who underwent elective open or laparoscopic colorectal cancer surgery between 2015 and 2019 at a single center was studied. The anesthetic technique used was categorized into either GA or GA + RA using a prospective proforma. The relationship between each anesthetic technique and perioperative clinicopathological characteristics was examined using binary logistic regression analysis.The majority of patients were male (54%), younger than 65 years (41%), either normal or overweight (64%), and were nonsmokers (47%). Also, the majority of patients underwent open surgery (60%) and received mainly general + regional anesthetic technique (80%). On univariate analysis, GA + RA was associated with a lower day 4 CRP (≤150/>150 mg/L) concentration. On day 4, postoperative CRP was associated with anesthetic technique [odds ratio (OR) 0.58; confidence interval (CI) 0.31-1.07; P = .086], age (OR 0.70; CI 0.50-0.98; P = .043), sex (OR 1.15; CI 0.95-2.52; P = .074), smoking (OR 1.57; CI 1.13-2.19; P = .006), preoperative mGPS (OR 1.55; CI 1.15-2.10; P = .004), and preoperative dexamethasone (OR 0.70; CI 0.47-1.03; P = .072). On multivariate analysis, day 4 postoperative CRP was independently associated with anesthetic technique (OR 0.56; CI 0.32-0.97; P = .039), age (OR 0.74; CI 0.55-0.99; P = .045), smoking (OR 1.58; CI 1.18-2.12; P = .002), preoperative mGPS (OR 1.41; CI 1.08-1.84; P = .012), and preoperative dexamethasone (OR 0.68; CI 0.50-0.92; P = .014).There was a modest but an independent association between RA and a lower magnitude of the postoperative SIR. Future work is warranted with multicenter RCT to precisely clarify the relationship between anesthesia and the magnitude of the postoperative SIR.

The relationship between anaesthetic technique, clinicopathological characteristics and the magnitude of the postoperative systemic inflammatory response in patients undergoing elective surgery for colon cancer.

BACKGROUND/AIM: The magnitude of the postoperative systemic inflammatory response (SIR) is now recognised to be associated with both short and long-term outcomes in patients undergoing surgery for colon cancer. During such surgery, it is unclear whether the anaesthetic regimens influence the magnitude of the postoperative SIR, independent of other factors. The aim of the present study was to examine the association between anaesthetic agents, clinicopathological characteristics and the magnitude of the postoperative SIR in patients undergoing elective surgery for colon cancer. METHODS: Patients with colon cancer who underwent elective open or laparoscopic surgery between 2008 and 2016 (n = 409) were studied at a single center. The relationship between type of anaesthesia, surgical technique; open (n = 241) versus laparoscopic (n = 168) and clinicopathological characteristics was examined by using chi-square testing. The chi-square test was used to determine which anaesthetic group influences the POD 2 CRP for only patients undergoing elective open colon surgery. RESULTS: The majority of patients were <75 years old, male, normal weight or obese, underwent open surgery and had regional anaesthesia, in particular an epidural approach. There was a significant association between type of anaesthesia and post-operative CRP on day 2 (p <0.001) in patients undergoing open surgery but not laparoscopic surgery. Other factors associated with type of anaesthesia included; year of operation (p <0.01), surgical technique (p <0.001), and preoperative dexamethasone (p <0.01). CONCLUSION: In patients undergoing surgery for elective colon cancer, the type of anaesthesia varied over time. The type of anaesthesia appears to influence the magnitude of the postoperative SIR on post-operative day 2 in open surgery but not laparoscopic surgery. Future work using prospective study design is required to better define this relationship.
