BackgroundPrescribing that is not concordant with guidelines is increasingly referred to as clinical inertia (CI). However, CI may be only apparent, and the absence of decision may actually reflect appropriate inaction as a result of good clinical reasoning. Our study aimed to: (i) elucidate GPs inverted question mark beliefs regarding CI and the risk of CI in their own practice, (ii) identify modifiable provider-related factors associated with CI.MethodsWe conducted 8 group interviews with 114 general practitioners (GP) in Belgium, and used an integrated approach of thematic analysis.ResultsOur results call for a redefinition of CI, in order to take into account the GPs inverted question mark extended health-promoting role, and acknowledge that inaction or delayed action follows a process of clinical reasoning that takes into account the patients inverted question mark preferences, and that is appropriate most of the time. However, the participants in our study did acknowledge that the risk of CI exists in practice. The main factor of such a risk is when GPs feel overwhelmed and disempowered, due to characteristics of either the patients or the health care system, including contradictions between guidelines and reimbursement policies.ConclusionsAlthough situations of clinical inertia exist in practice and need to be prevented or corrected, the term clinical inertia could potentially increase the already existing gap between general practice and specialised care, whereas sustained efforts toward more collaborative work and integrated care are called for.

Introduction: Dipeptidyl peptidase-4 (DPP-4) inhibitors (gliptins) occupy a growing place in the armamentarium of drugs used for the management of hyperglycemia in type 2 diabetes, although some safety concerns have been raised in recent years. Areas covered: An updated review providing an analysis of available safety data (meta-analyses, randomized controlled trials, observational cohort and case-control studies and pharmacovigilance reports) with five commercialized DPP-4 inhibitors (sitagliptin, vildagliptin, saxagliptin, alogliptin, linagliptin). A special focus is given to overall safety profile; pancreatic adverse events (AEs) (acute pancreatitis, pancreatic cancer); overall cardiovascular safety (myocardial infarction and stroke); congestive heart failure concern and finally, safety in special populations (elderly, renal impairment). Expert opinion: The good tolerance/safety profile of DPP-4 inhibitors has been largely confirmed, including in more fragile populations (elderly, renal impairment) with almost no increased risk of infection or gastrointestinal AEs, no weight gain and a minimal risk of hypoglycemia. Although an increased risk of acute pancreatitis and pancreatic cancer was suspected, the complete set of available data appears reassuring so far. Cardiovascular safety of DPP-4 inhibitors has been proven but an unexpected increased risk of heart failure has been reported which should be confirmed in ongoing trials and better understood. Further postmarketing surveillance is recommended. [less ▲]

Inhibitors of sodium-glucose co-transporter type 2 (SGLT2) are proposed as a novel approach for the management of type 2 diabetes mellitus (T2DM). Several compounds are already available in many countries (dapagliflozin, canagliflozin, empagliflozin and ipragliflozin) and some others are in a late phase of development. The available SGLT2 inhibitors share similar pharmacokinetic characteristics, with a rapid oral absorption, a long elimination half-life allowing once-daily administration, an extensive hepatic metabolism mainly via glucuronidation to inactive metabolites, the absence of clinically relevant drug-drug interactions and a low renal elimination as parent drug. SGLT2 co-transporters are responsible for reabsorption of most (90 %) of the glucose filtered by the kidneys. The pharmacological inhibition of SGLT2 co-transporters reduces hyperglycaemia by decreasing renal glucose threshold and thereby increasing urinary glucose excretion. The amount of glucose excreted in the urine depends on both the level of hyperglycaemia and the glomerular filtration rate. Results of numerous placebo-controlled randomised clinical trials of 12-104 weeks duration have shown significant reductions in glycated haemoglobin (HbA1c), resulting in a significant increase in the proportion of patients reaching HbA1c targets, and a significant lowering of fasting plasma glucose when SGLT2 inhibitors were administered as monotherapy or in addition to other glucose-lowering therapies including insulin in patients with T2DM. In head-to-head trials of up to 2 years, SGLT2 inhibitors exerted similar glucose-lowering activity to metformin, sulphonylureas or sitagliptin. The durability of the glucose-lowering effect of SGLT2 inhibitors appears to be better; however, this remains to be more extensively investigated. The risk of hypoglycaemia was much lower with SGLT2 inhibitors than with sulphonylureas and was similarly low as that reported with metformin, pioglitazone or sitagliptin. Increased renal glucose elimination also assists weight loss and could help to reduce blood pressure. Both effects were very consistent across the trials and they represent some advantages for SGLT2 inhibitors when compared with other oral glucose-lowering agents. The pharmacodynamic response to SGLT2 inhibitors declines with increasing severity of renal impairment, and prescribing information for each SGLT2 inhibitor should be consulted regarding dosage adjustments or restrictions in moderate to severe renal dysfunction. Caution is also recommended in the elderly population because of a higher risk of renal impairment, orthostatic hypotension and dehydration, even if the absence of hypoglycaemia represents an obvious advantage in this population. The overall effect of SGLT2 inhibitors on the risk of cardiovascular disease is unknown and will be evaluated in several ongoing prospective placebo-controlled trials with cardiovascular outcomes. The impact of SGLT2 inhibitors on renal function and their potential to influence the course of diabetic nephropathy also deserve more attention. SGLT2 inhibitors are generally well-tolerated. The most frequently reported adverse events are female genital mycotic infections, while urinary tract infections are less commonly observed and generally benign. In conclusion, with their unique mechanism of action that is independent of insulin secretion and action, SGLT2 inhibitors are a useful addition to the therapeutic options available for the management of T2DM at any stage in the natural history of the disease. Although SGLT2 inhibitors have already been extensively investigated, further studies should even better delineate the best place of these new glucose-lowering agents in the already rich armamentarium for the management of T2DM.

Canagliflozin is an inhibitor of sodium-glucose cotransporters type 2 (SGLT2) that are present in renal tubules. This specific insulin-independent mechanism promotes glucosuria, which results in a reduction in fasting and postprandial glycaemia and a decrease of glycated haemoglobin (HbA1c). Furthermore, canagliflozin promotes weight loss and lowers arterial (mainly systolic) blood pressure. Its efficacy is decreased in patients with renal insufficiency and the treatment should be stopped if estimated glomerular filtration rate is below 45 ml/min/1.73 m². Both the efficacy and safety of canagliflozin have been investigated in 24 to 104-week controlled trials versus placebo or versus an active comparator (glimepiride or sitagliptin). The mean reduction in HbA1c averages 0.75% when added to other treatments, as compared to placebo. The 100 mg dose is as active as sitagliptin 100 mg while the 300 mg canagliflozin dose is even more efficacious. Adverse events are mostly mycotic genital infections and more rarely mild urinary tract infections. Caution is required in elderly patients and the risk of volume depletion should be checked (hypotension). Hypoglycaemia may occur only in patients already treated with an insulin-secreting agent or insulin. Canagliflozin is commercialized under the trade name Invokana®, at the doses of 100 mg and 300 mg once daily, for the treatment of type 2 diabetes. [less ▲]

Any pharmacological treatment should ideally be effective and safe. The supervision of an ongoing therapy should control that individualized goals are reached while tolerance and safety are present. In case of not reaching the predefined objectives, the causes of failure should first be screened (for instance, exclusion of poor patient compliance), and the treatment should be then optimized : dose adjustment, add-on of another drug (if possible synergistic combination) and/or shift to a more effective pharmacological therapy. In some cases, therapeutic monitoring may be useful or even mandatory in order to better adjust drug dosing and thus guarantee both efficacy and safety. [less ▲]

Triplixam® is a fixed dose combination of three well known antihypertensive agents, with complementary activities, to control blood pressure in patients with arterial hypertension : perindopril, an angiotensin converting enzyme inhibitor, indapamide, un diuretic whith thiazide-like effects but also specific properties, and amlodipine, a long-acting calcium antagonist of the dihydropyridine family. The potential synergic action allows better control of blood pressure with once daily administration, while limiting the incidence of adverse events. Various presentations with different dosages are available to facilitate individualized therapy. Warnings and precautions for use of every molecule should of course be respected. Such a fixed dose combination should contribute to limit clinical inertia and to improve therapeutic compliance. [less ▲]

Initiating a new pharmacological therapy is an important step in the global medical approach. Such a decision is the final step of a careful reasoning and should respect some rules in order to guarantee the best efficacy, but also safety for the patient. Clinical inertia should be avoided, but the essential principles of the evidence based medicine should also be taken into account. This concise article summarizes the main fundamental rules and cautions that should be respected by any clinician when initiating a new pharmacological therapy. [less ▲]

The pharmacological therapy of hyperglycaemia in type 2 diabetes becomes increasingly complex. After failure of metformin monotherapy, several choices are possible. In clinical practice, the most common dilemma is to choose between adding a sulphonylurea or adding a dipeptidyl peptidase-4 inhibitor (gliptin). This review analyses the arguments in favour of one or the other pharmacological option, based upon criteria of efficacy, tolerance, safety, easiness of use, use in at risk populations and, last but not least, cost of therapy. In general, a patient-centered approach is recommended with an individualization of the therapy in function of the characteristics of each patient with the aim to obtain the best benefits/risks ratio, at an affordable cost.

Failure to initiate or intensify therapy according to evidence-based guidelines is increasingly being acknowledged as a phenomenon that contributes to inadequate management of chronic conditions, and is referred to as clinical inertia. However, the number and complexity of factors associated with the clinical reasoning that underlies the decision-making processes in medicine calls for a critical examination of the consistency of the concept. Indeed, in the absence of information on and justification of treatment decisions that were made, clinical inertia may be only apparent, and actually reflect good clinical practice. This integrative review seeks to address the factors generally associated with clinical inaction, in order to better delineate the concept of true clinical inertia. [less ▲]
