Show moreBACKGROUND\nAiming at partly controlled asthma (PCa) instead of controlled asthma (Ca) might decrease asthma medication use. Biomarkers, such as the fraction of exhaled nitric oxide (Feno), allow further tailoring of treatment.\nOBJECTIVE\nWe sought to assess the cost-effectiveness and clinical effectiveness of pursuing PCa, Ca, or Feno-driven controlled asthma (FCa).\nMETHODS\nIn a nonblind, pragmatic, cluster-randomized trial in primary care, adults (18-50 years of age) with a doctor's diagnosis of asthma who were prescribed inhaled corticosteroids were allocated to one of 3 treatment strategies: (1) aiming at PCa (Asthma Control Questionnaire [ACQ] score <1.50); (2) aiming at Ca (ACQ score <0.75); and (3) aiming at FCa (ACQ score <0.75 and Feno value <25 ppb). During 12 months' follow-up, treatment was adjusted every 3 months by using an online decision support tool. Outcomes were incremental cost per quality-adjusted life year gained, asthma control (ACQ score), quality of life (Asthma Quality of Life Questionnaire score), asthma medication use, and severe exacerbation rate.\nRESULTS\nSix hundred eleven participants were allocated to the PCa (n = 219), Ca (n = 203), or FCa (n = 189) strategies. The FCa strategy improved asthma control compared with the PCa strategy (P < .02). There were no differences in quality of life (P ≥ .36). Asthma medication use was significantly lower for the PCa and FCa strategies compared with the Ca strategy (medication costs: PCa, $452; Ca, $551; and FCa, $456; P ≤ .04). The FCa strategy had the highest probability of cost-effectiveness at a willingness to pay of $50,000/quality-adjusted life year (86%; PCa, 2%; Ca, 12%). There were no differences in severe exacerbation rate.\nCONCLUSION\nA symptom- plus Feno-driven strategy reduces asthma medication use while sustaining asthma control and quality of life and is the preferred strategy for adult asthmatic patients in primary care.

Show moreOBJECTIVES: to determine (cost)-effectiveness of a stepped-care intervention programme among subjects ≥75 years who screened positive for depressive symptoms in general practice. DESIGN: the pragmatic cluster-randomised controlled trial with 12-month follow-up. SETTING: sixty-seven Dutch general practices. SUBJECTS: two hundred and thirty-nine subjects ≥75 years screened positive for untreated depressive symptoms (15-item Geriatric Depression Scale ≥5). METHODS: usual care (34 practices, 118 subjects) was compared with the stepped-care intervention (33 practices, 121 subjects) consisting of three steps: individual counselling; Coping with Depression course; and-if indicated-referral back to general practitioner to discuss further treatment. Measurements included severity of depressive symptoms [Montgomery-Åsberg Depression Rating Scale (MADRS)], quality of life, mortality and costs. RESULTS: at baseline subjects mostly were mildly/moderately depressed. At 6 months MADRS scores had improved more in the usual care than the intervention group (-2.9 versus -1.1 points, P = 0.032), but not at 12 months (-3.1 versus -4.6, P = 0.084). No significant differences were found within two separate age groups (75-79 years and ≥80 years). In intervention practices, 83% accepted referral to the stepped-care programme, and 19% accepted course participation. The control group appeared to have received more psychological care. CONCLUSIONS: among older subjects who screened positive for depressive symptoms, an offered stepped-care intervention programme was not (cost)-effective compared with usual care, possibly due to a low uptake of the course offer.Trial registration: www.controlled-trials.com/ISRCTN 71142851v.

Show moreBACKGROUND: Sciatica is a common condition worldwide that is characterized by radiating leg pain and regularly caused by a herniated disc with nerve root compression. Sciatica patients with persisting leg pain after six to eight weeks were found to have similar clinical outcomes and associated costs after prolonged conservative treatment or surgery at one year follow-up. Guidelines recommend that the team of professionals involved in sciatica care and patients jointly decide about treatment options, so-called interprofessional shared decision making (SDM). However, there are strong indications that SDM for sciatica patients is not integrated in daily practice. We designed a study aiming to explore the barriers and facilitators associated with the everyday embedding of SDM for sciatica patients. All related relevant professionals and patients are involved to develop a tailored strategy to implement SDM for sciatica patients. METHODS: The study consists of two phases: identification of barriers and facilitators and development of an implementation strategy. First, barriers and facilitators are explored using semi-structured interviews among eight professionals of each (para)medical discipline involved in sciatica care (general practitioners, physical therapists, neurologists, neurosurgeons, and orthopedic surgeons). In addition, three focus groups will be conducted among patients. Second, the identified barriers and facilitators will be ranked using a questionnaire among a representative Dutch sample of 200 GPs, 200 physical therapists, 200 neurologists, all 124 neurosurgeons, 200 orthopedic surgeons, and 100 patients. A tailored team-based implementation strategy will be developed based on the results of the first phase using the principles of intervention mapping and an expert panel. DISCUSSION: Little is known about effective strategies to increase the uptake of SDM. Most implementation strategies only target a single discipline, whereas multiple disciplines are involved in SDM among sciatica patients. The results of this study can be used as an example for implementing SDM in other patient groups receiving multidisciplinary complex care (e.g., elderly) and can be generalized to other countries with similar context, thereby contributing to a worldwide increase of SDM in preference sensitive choices.
