Abstract

This review seeks to establish, through the recent available literature, the prevalence of therapeutic intensification delay and its sequences in poorly controlled Type 2 Diabetes Mellitus (T2DM) patients. The strategy identified studies exploring the clinical inertia and its associated factors in the treatment of patients with T2DM. A total of 25 studies meeting the pre-established quality criteria were included in this review. These studies were conducted between 2004 and 2021 and represented 575,067 patients diagnosed with T2DM. Trusted electronic bibliographic databases, including Medline, Embase, and the Cochrane Central Register of Controlled Trials, were used to collect studies by utilizing a comprehensive set of search terms to identify Medical Subject Headings (MeSH) terms. Most o the studies included in this review showed clinical inertia rates over 50% of T2DM patients. In the USA, clinical inertia ranged from 35.4% to 85.8%. In the UK, clinical inertia ranged from 22.1% to 69.1%. In Spain, clinical inertia ranged from 18.1% to 60%. In Canada, Brazil, and Thailand, clinical inertia was reported as 65.8%, 68%, and 68.4%, respectively. The highest clinical inertia was reported in the USA (85.8%). A significant number of patients with T2DM suffered from poor glycemic control for quite a long time before treatment intensification with oral antidiabetic drugs (OADs) or insulin. Barriers to treatment intensification exist at the provider, patient, and system levels. There are deficiencies pointed out by this review at specialized centers in terms of clinical inertia in the management of T2DM including in developed countries. This review shows that the earlier intensification in the T2DM treatment is appropriate to address issues around therapeutic inertia.

TL;DR

This systematic review of 25 studies (575,067 patients with T2DM, published 2004–2021) found that clinical inertia was common, often exceeding 50%, with delayed treatment intensification across many countries and health systems. The authors conclude that earlier intensification is needed and that barriers exist at provider, patient, and system levels.

Key findings

  • Clinical inertia prevalence was over 50% in most included studies. By country, it ranged from 35.4% to 85.8% in the USA (average 60.6%), 22.1% to 69.1% in the UK (average 45.6%), 31.0% to 42.3% in France (average 36.6%), and 18.1% to 60.0% in Spain (average 39.0%). Canada, Brazil, and Thailand reported 65.8%, 68%, and 68.4%, respectively. The highest was in the USA (85.8%) and the lowest in Spain (18.1%).
  • Treatment intensification was often delayed for long periods: Khunti et al. reported a median time of more than seven years between initiation and intensification with additional OADs among patients on one, two, or three OADs; Lanzinger et al. found average times in poor glycemic control of 12.6, 9.9, and 8.4 months for HbA1c above 7.0%, 7.5%, and 8.0%; Romera et al. reported a median time to first intensification of 456 days (15.2 months); Mata-Cases et al. reported median times of 17.1 months for HbA1c 8.0–9.9% and 10.1 months for HbA1c above 10%.
  • Factors associated with clinical inertia included patient reluctance, fear of side effects, higher HbA1c percentage, OAD started by a diabetologist, use of more than one OAD, longer diabetes duration, increased postprandial glycemia, total cholesterol, physical inactivity, communication gaps, older age, zero DCSI, zero CIC score, CCB use, CAD diagnosis, multimorbidity, and Black ethnicity. Higher CCI score, POS insurance, high index HbA1c, baseline endocrinologist visit, and use of comedications were associated with reduced likelihood of clinical inertia.
  • Barriers to treatment intensification were identified at provider, patient, and system levels. The paper cites causes accounting for 50%, 30%, and 20% of therapeutic inertia, respectively, and notes that most participants in one qualitative study were unaware of the term “clinical inertia.”

Methods

  • Systematic review using the PICo framework, with searches of Medline, Embase, and the Cochrane Central Register of Controlled Trials; studies published from database inception to 31 December 2021, in English, including patients aged ≥18 years with T2DM.
  • The initial search identified 3196 studies; after removing 574 duplicates and screening, 25 studies met inclusion criteria. These included 15 retrospective, 4 prospective, 5 cross-sectional, and 1 qualitative study, covering 575,067 T2DM patients.
  • Data were extracted with a standardized form following PRISMA recommendations; risk of bias was assessed with the Newcastle–Ottawa Scale, with scores ≥6 considered high quality. The review reports a narrative synthesis and states it lacks a quantitative approach.

Limitations

  • Stated: the review lacks a quantitative approach, and future meta-analysis would contribute more to understanding clinical inertia.
  • Stated: the review could not address the effect of the COVID-19 pandemic on T2DM clinical inertia; only three included studies were conducted in 2020 and 2021.
  • Evident from the text: criteria for clinical inertia varied across studies, prevalence estimates were not pooled, and findings were heterogeneous across countries and health systems, including conflicting results on HbA1c and diabetes duration.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-16.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-16.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
