Objectives To evaluate the effectiveness of inviting teenagers to general practice consultations to discuss health behaviour concerns and appropriate follow up care. Design Randomised controlled trial, with participants randomised to a consultation (intervention) or usual care (control). Questionnaires completed at baseline, 3 months, and 12 months. Setting Eight general practices in Hertfordshire, England. Participants 1516 teenagers aged 14-15 years. Intervention Consultations with practice nurses to discuss health concerns and develop plans for healthier lifestyles. Main outcome measures Mental and physical health, "stage of change" for health related behaviour, and use of health services. Results At baseline 970 teenagers completed questionnaires; 23% smoked, 35% had been drunk in the previous three months, 64% considered they ate unhealthily, 39% took little exercise, and 36% had possible depression. 41% (304) of teenagers invited attended for a consultation; over one third (112) were offered follow up care. More intervention group teenagers reported positive movement in stage of change for diet and exercise and in at least one of four behaviours (diet, exercise, smoking, drinking alcohol) at 3 months (41% v 31%, P < 0.01), but this did not persist at 12 months. There was marginally more positive change in actual behaviour by intervention teenagers at 3 months (16% v 12%, P=0.06). Recognition of possible depression resulted in improved mental health outcomes at 3 and 12 months. 97% of attenders said they would recommend the intervention to a friend. Conclusions Change in behaviour was slight but encouraging, and the intervention was well received and relatively cheap.

A questionnaire based survey undertaken in north London secondary schools supported the need for designated hospital facilities for teenagers: 53 per cent of young people who had been admitted to a paediatric ward, and 81 per cent of those admitted to an adult ward, had felt out of place there; 77 per cent of the total (347 adolescents) surveyed, thought a specific teenagers' room would be an improvement in service. In this article, the authors present the research.

Hospital systems, payers, and regulators have focused on reducing length of stay (LOS) and early readmission, with uncertain benefit. Interpretable machine learning (ML) may assist in transparently identifying the risk of important outcomes. We conducted a retrospective cohort study of hospitalizations at a tertiary academic medical center and its branches from January 2011 to May 2018. A consecutive sample of all hospitalizations in the study period were included. Algorithms were trained on medical, sociodemographic, and institutional variables to predict readmission, length of stay (LOS), and death within 48-72 h. Prediction performance was measured by area under the receiver operator characteristic curve (AUC), Brier score loss (BSL), which measures how well predicted probability matches observed probability, and other metrics. Interpretations were generated using multiple feature extraction algorithms. The study cohort included 1,485,880 hospitalizations for 708,089 unique patients (median age of 59 years, first and third quartiles (QI) [39, 73]; 55.6% female; 71% white). There were 211,022 30-day readmissions for an overall readmission rate of 14% (for patients ≥65 years: 16%). Median LOS, including observation and labor and delivery patients, was 2.94 days (QI [1.67, 5.34]), or, if these patients are excluded, 3.71 days (QI [2.15, 6.51]). Predictive performance was as follows: 30-day readmission (AUC 0.76/BSL 0.11); LOS > 5 days (AUC 0.84/BSL 0.15); death within 48-72 h (AUC 0.91/BSL 0.001). Explanatory diagrams showed factors that impacted each prediction.

Objectives. The main objective of the study was to look at satisfaction with the teenager's last consultation and any reasons for dissatisfaction. A further objective was to look at common teenage health concerns to identify how many teenagers had been concerned about them, where they sought advice, and to look at ratings of this advice.Method. Questionnaires were completed as part of a continuing evaluation of a novel sex education programme in 38 schools in 1997 and provided the data. The particular items reported in this study were related to satisfaction with the last GP consultation and reasons for dissatisfaction, health concerns and who (if anybody) was approached to address these concerns, and comments on services used. 5152 teenagers (51.8% male and 47.8% female) completed the questionnaires in a school lesson under conditions of complete confidentiality.Results. Over 86% of adolescents were apparently satisfied with their last consultation with a GP, although several possible reasons were identified for any dissatisfaction. Health concerns were identified and sources of help were considered and compared; no obvious levels of relative dissatisfaction with services were noted. A large number of teenagers identified apparent concerns but did not seek help for these concerns. Conclusions.Adolescents are largely satisfied with the services available in primary care. A number of teenagers do not seek help for their own individual concerns. Encouraging teenagers to attend when they perceive a health problem may help provide a more sensitive primary care service.
