Improving Access to Psychological Therapies (IAPT), an NHS England service providing talking therapies, is meeting its target recovery rate of 50%. However, engagement in treatment, as well as recovery rates, may be lower for some groups.

To assess variation in treatment completion and recovery rates by demographic and socioeconomic group and to describe rates of further referrals for patients to IAPT and secondary mental health services.

Using 121 548 administrative records for 2019–2020 and 2022–2023 for the Norfolk and Waveney area, we estimated associations of age, gender, ethnicity and deprivation with the likelihood of treatment completion and recovery using logistic regression modelling. We also described rates of further referrals.

Younger people and those living in deprived areas were less likely to recover or complete treatment, with those aged 16–17 years (n = 735) having the lowest adjusted odds for recovery (adjusted odds ratio = 0.5, 95% CI: 0.5–0.6) compared with those aged 36–70 years, and those aged 18–24 years (n = 23 563) having the lowest rate of completion (adjusted odds ratio = 0.5, 95% CI: 0.5–0.6). Further referrals before April 2022 were recorded for 45.4% of 6513 patients who had completed treatment and 68.8% of 9469 who had not completed treatment, and for 39.4% of 2007 recovered patients in 2019–2020 and 53.1% of 1586 who had not recovered. Non-completers had relatively more further referrals to secondary mental health services compared with completers (43.6% v. 22.8%; P < 0.01).

Younger people and those living in deprived areas have lower recovery and completion rates. Those who have completed treatment and not recovered have higher rates of further referrals.

Integration of depression treatment into primary care could improve patient outcomes in low-resource settings. Losses along the depression care cascade limit integrated service effectiveness. This study identified patient-level factors that predicted detection of depressive symptoms by nurses, referral for depression treatment, and uptake of counseling, as part of integrated care in KwaZulu-Natal, South Africa.

This was an analysis of baseline data from a prospective cohort. Participants were adult patients with at least moderate depressive symptoms at primary care facilities in Amajuba, KwaZulu-Natal, South Africa. Participants were screened for depressive symptoms prior to routine assessment by a nurse. Generalized linear mixed-effects models were used to estimate associations between patient characteristics and service delivery outcomes.

Data from 412 participants were analyzed. Nurses successfully detected depressive symptoms in 208 [50.5%, 95% confidence interval (CI) 38.9–62.0] participants; of these, they referred 76 (36.5%, 95% CI 20.3–56.5) for depression treatment; of these, 18 (23.7%, 95% CI 10.7–44.6) attended at least one session of depression counseling. Depressive symptom severity, alcohol use severity, and perceived stress were associated with detection. Similar factors did not drive referral or counseling uptake.

Nurses detected patients with depressive symptoms at rates comparable to primary care providers in high-resource settings, though gaps in referral and uptake persist. Nurses were more likely to detect symptoms among patients in more severe mental distress. Implementation strategies for integrated mental health care in low-resource settings should target improved rates of detection, referral, and uptake.
