Striking is the small number of studies investigating another joint (18%) than the knee (82%). Exercise is the most common treatment evaluated and should be accompanied with education to effectuate a behavioural change in physical activity of people with OA. No new insights in the field of braces (or orthoses) and in the field of acupuncture were found.
Few studies have evaluated the use of amitriptyline in musculoskeletal complaints. Although amitriptyline may be effective in musculoskeletal complaints, more studies are required to establish for whom amitriptyline works better than other analgesics.
Objective. To determine the incidence and prevalence of knee osteoarthritis (OA) using codified and narrative data from general practices throughout The Netherlands.Methods. This retrospective cohort study was conducted using the Integrated Primary Care Information database. Patients with codified knee OA were selected, and an algorithm was developed to identify patients with narratively diagnosed knee OA only. Point prevalence proportions and incidence rates among people age ≥30 years were assessed from 2008 to 2019. The association of comorbidities with codified knee OA was analyzed using multivariable logistic regression.Results. The positive predicted value of narratively diagnosed knee OA only was 94.0% (95% confidence interval [95% CI] 87.4-100%) and for codified knee OA 96.0% (95% CI 90.6-100%). Including narrative data in addition to codified data resulted in a prevalence 1.83-2.01 times higher (over the study years); prevalence increased from 5.8% to 11.8% between 2008 and 2019. The incidence rate was 1.93-2.28 times higher and increased from 9.98 per 1,000 person-years to 13.8 per 1,000 person-years between 2008 and 2019. Among patients with codified knee OA, 39.4% were previously diagnosed narratively with knee OA, on average ~3 years earlier. Comorbidities influenced the likelihood of being recorded with codified knee OA.Conclusion. Our study of a Dutch primary care database showed that current incidence and prevalence estimates based on codified data alone from electronic health records are underestimated. Narrative data can be incorporated in addition to codified data to identify knee OA patients more accurately.
Objectives To examine the incidence, prevalence and trends for opioid prescriptions in patients with OA. Furthermore, types of opioids prescribed and long-term prescription rates were examined. Finally, the patient characteristics associated with the prescription of opioids were assessed. Methods A population-based cohort study was conducted using the Integrated Primary Care Information database. Incidence and prevalence of opioid prescriptions were calculated for the period 2008–2017. Logistic regression was used to assess which patient characteristics were associated with opioid prescriptions. Results In total, 157 904 OA patients were included. The overall prescription rate remained fairly stable, at around 100 incident and 170 prevalent prescriptions per 1000 person years. However, the incident prescription rate for oxycodone increased from 7.1 to 40.7 per 1000 person years and for fentanyl from 4.2 to 7.4 per 1000 person years. The incident prescription rate for paracetamol/codeine decreased from 63.0 to 13.3 per 1000 person years. Per follow-up year, long-term use was found in 3% of the patients with incident OA. Finally, factors associated with more prescriptions were increasing age, OA in ≥2 joint groups [odds ratio (OR) 1.56; 95% CI: 1.51, 1.65] and the presence of other musculoskeletal disorders (OR 4.91; 95% CI: 4.76, 5.05). Men were less likely to be prescribed opioids (OR 0.78; 95% CI: 0.76, 0.80). Conclusion Prescription rates for opioids remained stable, but types of opioids prescribed changed. Oxycodone and fentanyl were increasingly prescribed, while prescriptions of paracetamol/codeine decreased. Since the benefit of opioids for OA pain is questionable and side effects are common, opioids should be prescribed with caution.
Background: The difference in mortality between emergency and elective surgery for malignant colonic obstruction is more than 5% in healthy patients below the age of 65 and increases with age to around 20%. Emergency surgery can be avoided by endoscopic placement of a self-expandable metal stent (SEMS). Aim: To evaluate the effectiveness and safety of SEMS as ‘bridge to surgery’. Method: Between January 2001 and July 2008, SEMS were placed for acute malignant colonic obstruction in 45 patients (median age 72 years, range 35–91). Results: The procedure was technically successful in 43 patients (94%) with resolution of obstructive symptoms within 48 h in 87% of the patients. No perforations occurred during the procedure or while awaiting surgery. Two (4%) patients required a second endoscopic procedure. All patients underwent a single-stage surgical procedure. Postoperative mortality was 2.2% (n = 1). Histology showed advanced colorectal cancer (T3–4N1–2M0–1) in 75% of the patients. Conclusion: SEMS placement is a safe and effective procedure as bridge to surgery in patients presenting with colonic obstruction due to colorectal malignancy. This procedure carries a risk of serious complications well below that of the reported difference in mortality between emergency an elective surgery.
