The majority of the methodological developments in the field of cluster RCTs have been published in the more specialized fields of statistics and epidemiology. While statisticians and epidemiologists have the greatest need for this information, it is important that generic health services and primary care researchers have access to the principal findings of this research if they are to plan and conduct cluster RCTs appropriately.

We have outlined here the primary implications of adopting a cluster design and have highlighted that methods, some of which are easy to apply, do exist whereby cluster RCTs can be analysed appropriately. While we have identified a range of plausible methods, however, the choice of method and its actual implementation and interpretation should not be considered lightly, and expert statistical advice should be sought early in the planning of such studies. It should also be noted that the analysis options described are only appropriate for a completely randomized trial design with a continuous outcome. While the general approach to the analysis of binary data will be similar, whether cluster or individual level, the specifics of the analysis will be different. Similarly, more complex designs, such as stratified or matched designs, will require more sophisticated analysis strategies. 2

When planning a cluster RCT, it is important to think about the analysis strategy at the design phase as the choice of analysis approach may impact on the design of the trial. For example, to ensure that robust multilevel modelling can be undertaken, it is necessary that both sufficient clusters are recruited to the study and sufficient number of patients are available per cluster. 17

Considerable debate surrounds the choice of unit of analysis in cluster randomized trials. 2 , 18 Some authors stress that analysis should only be undertaken at the level of randomization; for example if a trial is randomized by practice, it should only be analysed by practice. Murray 2 argues that this emphasis on the unit of analysis may be misplaced and that attention should be focused rather on the appropriate specification of the model for the analysis, where the model selected should be well matched to the underlying structure of the data.

In conclusion, this study has demonstrated that adjustment for clustering can be applied to real-life data in a relatively straightforward manner, if advice and relevant software are available, and we encourage more routine adoption of appropriate analytical techniques.

Previous studies examining the etiology of CAP have provided widely differing results. Comparison is hampered by inherent epidemiologic differences in addition to lack of uniform inclusion criteria, study settings, and diagnostic methods. Despite rigorous attempts to identify a microbial etiology, 30%–64% of patients remain undiagnosed [ 3–12 ]. Studies applying molecular methods such as polymerase chain reaction (PCR) have yielded detection rates up to 86%, but highly specific patient selection criteria designed to optimize sample collection make comparisons difficult [ 13 ]. There is a dearth of population-based observational studies with high inclusion rates examining pneumonia incidence and etiology while avoiding overly selective inclusion criteria and applying modern diagnostic methods.

The aim of the present study was to prospectively investigate the frequency and etiology of CAP in a defined population, allowing for calculation of incidence, applying modern diagnostic tests, and comparing etiology with symptoms, risk factors, and outcomes.

This study took place at Landspitali University Hospital in Reykjavik Iceland (LUH). The LUH provides secondary care for the inhabitants of Reykjavik and nearby towns, comprising 63% of the national population. It also provides 90% of all intensive care in the country. Adults (≥18 years) admitted from December 1, 2008 to November 30, 2009 were screened for inclusion. Inclusion criteria were a new chest x-ray infiltrate and ≥2 additional symptoms: temperature >38.3°C or <36°C, diaphoresis, chills, new cough, chest pain, or new onset of dyspnea [ 6 , 14 ]. Exclusion criteria were as follows: admission to an acute care facility during the preceding 14 days; use of immunosuppressive medications (corticosteroids equivalent to ≥10 mg prednisolone daily, methotrexate, hydroxyurea, adalimumab, infliximab, etenercept, azathioprine, mycophenolate mofetil, or cyclosporine); ongoing treatment for a malignancy; receipt of a solid organ transplant; or human immunodeficiency virus infection.

Potential participants were approached within 24 hours of admission and underwent a structured interview, and data were collected on underlying diseases, subjective symptoms, and antimicrobial use before admission. Pneumonia severity index (PSI) and CURB-65 scores were calculated [ 15 , 16 ]. Outcomes were: length of stay (LOS), admission to intensive care units (ICUs), assisted ventilation, and in-house mortality. Outcomes were obtained retrospectively from patient charts. Vital status was cross-checked with national registry data after discharge from hospital.

The study was noninterventional but included additional diagnostic sampling. Sputum and blood were obtained for culture prior to in-hospital antimicrobial treatment and urine antigen testing was performed. An oropharyngeal swab was collected for PCR analysis. Results from physician-ordered etiological diagnostic testing were also included.

The procedure-specific risks of stroke, silent stroke, and bleeding emphasize the importance of acquiring data from randomized trials comparing NOAC therapy and VKAs in patients undergoing AF ablation. In a randomized trial with rivaroxaban (VENTURE-AF), 248 patients scheduled for ablation were randomly assigned to uninterrupted therapy with warfarin or rivaroxaban. 42 The incidence of thromboembolic and major bleedings events was low in both treatment arms (one patient in each).

Ongoing trials [AXAFA with apixaban (NCT02227550) and RE-CIRCUIT (NCT02348723) with dabigatran] will provide prospectively collected data on outcomes, including silent ischaemic brain lesions in patients undergoing AF ablation on uninterrupted NOAC therapy compared with uninterrupted warfarin. These trials are exploratory for outcomes such as stroke because of the low event rates, but they should shed some light on major bleeding rates and possibly provide information about the effect of NOAC therapy on silent strokes in patients undergoing AF ablation.

Although the use of transcatheter aortic valve implantation is increasing, surgical valve replacement with either bioprosthetic or mechanical valves is the more common approach, with mechanical prostheses having the advantage of durability but the disadvantages of thrombogenicity and need for life-long anticoagulation. An alternative to VKAs is needed and there was the hope that NOACs might fill the role, but the RE-ALIGN trial found even high-dose dabigatran neither safe nor effective. 43 In that trial, 252 patients with recent or remote valve replacement were randomly assigned to a VKA (guideline-directed INR target range) or to dabigatran adjusted to a trough plasma level of ≥50 ng/mL. The trial was stopped early due to excess stroke (nine patients in the dabigatran group and none in the warfarin group) and major bleeding (seven patients in the dabigatran vs. two in the warfarin group). There was also excess valve thrombosis with dabigatran. This small study, although not definitive, suggests that dabigatran is not effective and that NOACs should not be selected for patients with mechanical prosthetic valves.

The term ‘non-valvular AF’ was developed to define patient eligibility for enrolment in the historical warfarin trials, excluding individuals with rheumatic mitral stenosis and AF, which was associated with a high risk of stroke. Since these patients were not included in the trials that established the non-inferiority boundaries, they were excluded from the NOAC trials and therefore from the labelling indications for NOAC use. We have little or no data on the efficacy of NOACs in this population, and patients with mitral stenosis should not be treated with NOACs, although the threshold of severity warranting this prohibition has not been established.

Other types of valvular heart disease (VHD), such as mitral or tricuspid insufficiency and aortic stenosis or insufficiency, occur commonly in patients with AF. In the ROCKET AF trial, 43 14% of enrolled patients had clinically significant VHD, as did 26% in ARISTOTLE. 44 , 45 In each of these trials, the treatment effect of the NOAC compared with warfarin was similar in patients with and without VHD, but rivaroxaban was associated with a higher risk of bleeding than warfarin in patients with VHD. 44 In ARISTOTLE apixaban was associated with fewer bleeding complications in patients with and without VHD. 45 Patients in the ROCKET-AF 44 and ARISTOTLE 45 trials with VHD differed with regard to age, stroke risks, and history of previous stroke or systemic embolism. Thus, NOACs may be prescribed for patients with VHD other than mitral stenosis or mechanical valve prostheses. A few hundred patients with bioprosthetic valves were included in the ARISTOTLE and ENGAGE AF trials, but the results in these subgroups have not been reported. It may be reasonable to treat patients who have bioprosthetic valves with NOACs unless intracardiac thrombus or other features placing the patient at an unusually high risk of thromboembolism or bleeding are present.
