Long waits for non-urgent care remain a persistent challenge across many health systems, with backlogs exacerbated by pandemic disruptions. Delays can postpone treatment benefits, allow symptoms to worsen and reduce the eventual gains once care is delivered. Elective surgery pathways illustrate the variation in waits across conditions and countries, and the scale of unmet need linked to being on a list is substantial in several European settings. The consequences are not confined to health. Prolonged waits spill over into the labour market through sickness absence, reduced productivity, economic inactivity and delayed return to work. Evidence from orthopaedics and mental health consistently links longer waits to poorer outcomes, strengthening the case for prioritising by urgency and need and aligning capacity within and beyond healthcare to cut avoidable harm.
Health Burden of Delays
Health losses from waiting arise because benefits are delayed and because deterioration may occur while people await care. Cardiovascular pathways show important contrasts. For coronary artery bypass, longer waits have been linked to higher risk of emergency readmission rather than in-hospital mortality before the pandemic, while in post-pandemic periods longer waits were associated with higher mortality and longer length of stay. No corresponding mortality effect was reported for angioplasty before or after the pandemic. For common elective procedures, patient-reported outcomes in England show that longer waits for hip or knee replacement are associated with lower health-related quality of life, whereas similar patterns were not observed for varicose veins or inguinal hernia. Norwegian data indicate that extended waits for orthopaedic surgery did not increase mortality or healthcare utilisation, underlining heterogeneity by condition.

Mental health access is particularly sensitive to delay. In the United States, longer waits for veterans’ mental health services were associated with higher mortality through missed follow-up and disengagement from care. In early intervention for psychosis in England, waits beyond three months correlated with worse clinician-rated outcomes at 12 months. In oncology, waiting more than 30 days for lung cancer surgery in South Korea was associated with a 15% increase in mortality. Modelling the effect of an extra six weeks of waiting estimated losses in quality-adjusted life years (QALYs), with the largest reductions for hip and knee replacement, followed by hysterectomy, hernia repair, cholecystectomy, cataract surgery and coronary procedures. These findings support targeted reductions where the health payoff from timelier treatment is greatest.
Effects on Employment and Productivity
Delays can constrain labour supply, lengthen absence and increase reliance on benefits among working-age patients. For orthopaedic referrals in Norway, an additional ten days of waiting increased health-related work absence by 8.7 days over five years and raised the probability of entering permanent disability by 0.4 percentage points by year five. Effects were concentrated among people already on sick leave at referral, for whom an extra ten days generated 27.2 additional absence days over five years and a 1.3 percentage point rise in disability entry, with no measurable impact among those working at referral. In the Netherlands, a one-month increase in waiting time for mental health services reduced employment probability by two percentage points and increased receipt of sickness or disability benefits by one percentage point, with larger effects among those with lower educational attainment. In England, longer area-level waits for psychological therapies widened the employment gap between people in good and poor mental health by 1.5 percentage points per extra ten days and increased time away from work by one percentage point.
At a broader scale, analysis in England did not show a clear local relationship over time between overall waiting times and health-related benefit claims. Even so, patterns suggested weak positive links for mental health conditions and orthopaedics, consistent with evidence that these pathways are more sensitive to access delays. Together, these results indicate a channel through which waiting times hinder return to work, prolong sick leave and erode productivity, particularly where untreated pain, mobility limits or mental health conditions restrict job search, retention and performance.
Prioritisation and Capacity Constraints
Pandemic shocks magnified pressure on elective care. Surgical activity fell sharply, with average volumes dropping across many countries, and waiting times for common elective surgeries rose markedly over several years relative to 2019 levels. Although procedure volumes began to recover, waiting times remained elevated. With finite capacity and workforce constraints affecting both public and private providers, reducing delays requires a mix of demand management, productivity improvement, capacity expansion and better retention and recruitment.
Prioritisation can reduce aggregate health loss by shortening waits for those with higher urgency, need or severity. Across pathways, more urgent procedures such as coronary bypass tend to be scheduled sooner than less urgent ones such as cataract or joint replacement. Within a given procedure, there is evidence of shorter inpatient waits for hip replacement among patients with greater pain and mobility limitations, with prioritisation becoming more pronounced as waits lengthened between 2015 and 2019 and again in 2020. However, prioritisation appears weaker in outpatient pathways, and the introduction of condition- and severity-specific maximum recommended waits in Norway did not demonstrably improve prioritisation. Socioeconomic disparities persist, with lower socioeconomic status associated with longer waits in publicly funded care in several settings. These patterns point to the importance of clear criteria, robust scheduling and monitoring to ensure that those facing the greatest harm from delay are seen sooner.
Long waits for non-urgent care generate measurable health losses and, in pathways such as mental health and orthopaedics, translate into adverse labour market outcomes through extended absence, disability entry and reduced employment. Evidence supports prioritisation by need alongside measures that expand capacity, manage demand and improve productivity, focusing on conditions where delay carries the highest health and economic costs. For decision-makers, aligning resource allocation, scheduling and cross-sector support offers a practical route to reduce harm for patients and sustain workforce participation while protecting access for time-critical care.
