Long-term cost reduction of routine medications following a residential programme combining physical activity and nutrition in the treatment of type 2 diabetes: a prospective cohort study.

ABSTRACT: OBJECTIVES:To demonstrate that lifestyle modifications will reduce the cost of routine medications in individuals with type 2 diabetes (T2D), through a mechanism involving glycaemic control. DESIGN:A within-trial cost-medication analysis with a 1-year time horizon. SETTING:Controlled environment within the spa resort of Chatel-Guyon, France. PARTICIPANTS:Twenty-nine participants (aged 50-70?years) with T2D. INTERVENTIONS:A 1-year follow-up intervention, beginning with a 3-week residential programme combining high exercise volume (15-20?hours/week), restrictive diet (-500?kcal/day) and education. Participants continued their routine medication, independently managed by their general practitioner. MAIN OUTCOME MEASURES:Number of medications, number of pills, cost of medications and health-related outcomes. RESULTS:Twenty-six participants completed the 1-year intervention. At 1?year, 14 patients out of 26 (54%) stopped/decreased their medications whereas only 5 (19%) increased or introduced new drugs (?2=6.3, p=0.02). The number of pills per day decreased by 1.3±0.3 at 12?months (p<0.001). The annual cost of medications for T2D were lower at 1?year (€135.1±43.9) versus baseline (€212.6±35.8) (p=0.03). The regression coefficients on costs of routine medication were 0.507 (95% CI 0.056 to 0.959, p=0.027) for HbA1c and 0.156 (95% CI -0.010 to 0.322, p=0.06) for blood glucose levels. Diabetics patients with HbA1c >6.5% in the highest (last) quartile doubled their routine medication costs (66% vs 33%, p=0.037). CONCLUSIONS:Individuals with T2D reduced routine medication costs following a long-term lifestyle intervention that started with a 3-week residential programme. Combining high exercise volume, restrictive diet and education effectively supported the health of T2D. The main factor explaining reduced medication costs was better glycaemic control, independent of weight changes. Despite limitations precluding generalisability, cost-effective results of reduced medication should contribute to the evidence base required to promote lifestyle interventions for individuals with T2D.

Project description:BackgroundRoutine submission of pathologic specimens for histologic analysis following orthopedic surgery is a common and often required practice in the United States. Prior orthopedic studies have determined that these histologic examinations are of limited cost effectiveness and low clinical value because rarely do the pathology findings alter patient management. The purpose of this study was to evaluate the cost effectiveness and clinical significance of routine histologic examination of tissue specimens removed during ankle arthroscopy.MethodsBetween 2014 and 2018, 408 patients underwent ankle arthroscopy at a multi-center hospital system by 16 different orthopedic surgeons. The available pathology reports from these cases were retrospectively reviewed to determine if the routine histologic examination altered patient care. We compared the preoperative diagnosis to both the postoperative and histologic diagnoses. The total cost for these histologic examinations was estimated using 2017 Medicare physician fees released by the College of American Pathologists. Cost-effectiveness was estimated in 2017 US dollars by cost per discrepant and discordant diagnosis.ResultsOf the 408 patients who underwent ankle arthroscopy, 361 pathology reports were available for review. The prevalence of concordant diagnosis was 98.9% (357/361); the prevalence of discrepant diagnoses was 1.0% (4/361). There were no cases identified with a discordant diagnosis. Total estimated cost for all pathology specimens was $46 381 in 2017 US dollars. Cost per discrepant diagnosis was $11 595.ConclusionIn our study, histologic examination of surgical specimens following ankle arthroscopy had no effect on patient management, yet it increased costs. Routine examination of these pathologic specimens had a low rate of discrepant and/or discordant diagnoses. Based on our results, routine pathologic examination of ankle arthroscopy tissue specimens should be sent solely at the discretion of the orthopedic surgeon as opposed to being a mandated policy.Level of evidenceLevel IV, case series.

Project description:ObjectivesAustralian early parenting residential services provide interventions for families experiencing complex early parenting issues. Many services have recently shifted to virtual care models but the clinical effectiveness of such programmes is currently unknown. This study sought to test outcomes of a 'virtual' early parenting residential programme and to compare these with those of an in-person programme.DesignProspective cohort study; self-report questionnaires on admission, at discharge and 6-week follow-up.SettingAn early parenting residential unit in Sydney, Australia.ParticipantsConsecutive series of parent-child dyads admitted to the unit virtually (n=56) or in person (n=44) between August 2021 and January 2022.InterventionsParticipants in both groups received a 4-night/5-day intervention programme involving access to 24-hour support from a multidisciplinary team of health professionals. The in-person programme was delivered at a residential unit; the virtual programme involved provision of support via video calls, phone calls, SMS and emails.Primary and secondary outcome measuresInfant sleep, parenting self-efficacy (primary outcomes); parenting empathy, emotion, hostility, helplessness, mentalisation and stress (secondary outcomes).ResultsParents who received the virtual programme reported improvements from admission to discharge, and from admission to 6-week follow-up, in a range of areas including parenting self-efficacy, empathy, mentalisation, hostility, helplessness, stress and infant sleep resistance (ps<0.05). At 6 weeks, they also reported improvements in emotion and understanding related to their child (p<0.05). In contrast to expectation, outcomes at discharge and 6 weeks were not superior in the in-person group. In fact, at 6 weeks, parents who attended the virtual residential group reported significantly lower levels of parenting hostility and parenting stress, and greater levels of parenting confidence compared with those in the in-person group (ps<0.05).ConclusionsVirtual early parenting residential interventions may be effective in bringing positive changes for families, and there is no evidence to suggest that outcomes are inferior to those of in-person programmes.

Project description:Routine testing for SARS-CoV-2 is rare for institutes of higher education due to prohibitive costs and supply chain delays. During spring 2021, we routinely tested all residential students 1 to 2 times per week using pooled, RNA-extraction-free, reverse transcription quantitative PCR (RT-qPCR) testing of saliva at a cost of $0.43/sample with same-day results. The limit of detection was 500 copies/ml on individual samples, and analysis indicates 1,000 and 2,500 copies/ml in pools of 5 and 10, respectively, which is orders of magnitude more sensitive than rapid antigen tests. Importantly, saliva testing flagged 83% of semester positives (43,884 tests administered) and was 95.6% concordant with nasopharyngeal diagnostic results (69.0% concordant on the first test when the nucleocapsid gene (N1) cycle threshold (CT) value was >30). Moreover, testing reduced weekly cases by 59.9% in the spring despite far looser restrictions, allowing for more normalcy while eliminating outbreaks. We also coupled our testing with a survey to clarify symptoms and transmissibility among college-age students. While only 8.5% remained asymptomatic throughout, symptoms were disparate and often cold-like (e.g., only 37.3% developed a fever), highlighting the difficulty with relying on symptom monitoring among this demographic. Based on reported symptom progression, we estimate that we removed 348 days of infectious individuals by routine testing. Interestingly, viral load (CT value) at the time of testing did not affect transmissibility (R2 = 0.0085), though those experiencing noticeable symptoms at the time of testing were more likely to spread the virus to close contacts (31.6% versus 14.3%). Together, our findings support routine testing for reducing the spread of SARS-CoV-2. Implementation of cost- and resource-efficient approaches should receive strong consideration in communities that lack herd immunity. IMPORTANCE This study highlights the utility of routine testing for SARS-CoV-2 using pooled saliva while maintaining high sensitivity of detection (under 2,500 copies/ml) and rapid turnaround of high volume (up to 930 samples in 8 h by two technicians and one quantitative PCR [qPCR] machine). This pooled approach allowed us to test all residential students 1 to 2 times per week on our college campus during the spring of 2021 and flagged 83% of our semester positives. Most students were asymptomatic or presented with symptoms mirroring common colds at the time of testing, allowing for removal of infectious individuals before they otherwise would have sought testing. To our knowledge, the total per-sample consumable cost of $0.43 is the lowest to date. With many communities still lagging in vaccination rates, routine testing that is cost-efficient highlights the capacity of the laboratory's role in controlling the spread of SARS-CoV-2.

Project description:The clinical effectiveness of intensive lifestyle interventions in preventing or delaying diabetes in people at high risk has been established from randomised trials of structured, intensive interventions conducted in several countries over the past two decades. The challenge is to translate them into routine clinical settings. The objective of this review is to determine whether lifestyle interventions delivered to high-risk adult patients in routine clinical care settings are feasible and effective in achieving reductions in risk factors for diabetes.MEDLINE (PubMed), EMBASE, CINAHL, The Cochrane Library, Google Scholar, and grey literature were searched for English-language articles published from January 1990 to August 2009. The reference lists of all articles collected were checked to ensure that no relevant suitable studies were missed.We included RCTs, before/after evaluations, cohort studies with or without a control group and interrupted time series analyses of lifestyle interventions with the stated aim of diabetes risk reduction or diabetes prevention, conducted in routine clinical settings and delivered by healthcare providers such as family physicians, practice nurses, allied health personnel, or other healthcare staff associated with a health service. Outcomes of interest were weight loss, reduction in waist circumference, improvement of impaired fasting glucose or oral glucose tolerance test (OGTT) results, improvements in fat and fibre intakes, increased level of engagement in physical activity and reduction in diabetes incidence.Twelve from 41 potentially relevant studies were included in the review. Four studies were suitable for meta-analysis. A significant positive effect of the interventions on weight was reported by all study types. The meta-analysis showed that lifestyle interventions achieved weight and waist circumference reductions after one year. However, no clear effects on biochemical or clinical parameters were observed, possibly due to short follow-up periods or lack of power of the studies meta-analysed. Changes in dietary parameters or physical activity were generally not reported. Most studies assessing feasibility were supportive of implementation of lifestyle interventions in routine clinical care.Lifestyle interventions for patients at high risk of diabetes, delivered by a variety of healthcare providers in routine clinical settings, are feasible but appear to be of limited clinical benefit one year after intervention. Despite convincing evidence from structured intensive trials, this systematic review showed that translation into routine practice has less effect on diabetes risk reduction.

Project description:BackgroundPhysical activity is a critical component of lifestyle interventions to reduce body weight and maintain weight loss. The goal of this study was to examine the motivations to exercise in young men following a 5-month residential weight loss programme conducted in the Singapore military as part of National Service.MethodsWe conducted a sequential mixed methods study starting with three focus groups comprising 21 programme instructors. Fifteen former programme participants aged 20.8 years (±1.4) with an average body mass index (BMI) of 29.3 kg/m2 (±4.6) were interviewed in-depth over a total duration of 9 h. Another 487 current programme participants aged 20.8 years (±1.1), BMI 27.1 kg/m2 (±2.6), completed a survey on weight loss, physical fitness, and motivations to exercise using the Behaviours Regulating Exercise Questionnaire (BREQ-3). Qualitative data was coded thematically using the six constructs of exercise motivation described by self-determination theory: amotivation, external, introjected, identified and integrated regulation and intrinsic motivation. Quotes from interviewees were cross-tabulated according to their weight maintenance trajectories. BREQ-3 responses were analysed according to initial body mass index (BMI), percentage weight loss and fitness.ResultsOver the course of the residential programme interview and survey participants experienced an average weight loss of 15.6 kg (±6.5) and 13.0 kg (±5.4) respectively. Among the fifteen interviewees seven had gained no more than 34% of initial weight loss 6 months after completing the programme while another eight had gained more than 51%. We elicited three key themes from the data: (1) Barriers to exercise; (2) diminishing extrinsic motivation; and (3) unidentified exercise benefits. The integration of findings uncovered reinforcing motivational patterns in the areas of health, fitness, camaraderie and identified regulation. Narratives of self-acceptance and shift-work environments gave rise to potentially deleterious motivational patterns. Our findings suggest that successful transition from a residential programme to independent weight management requires a more deliberate pivot from predominantly extrinsic to intrinsic motivational approaches.ConclusionResidential programmes such as the one investigated here, should develop a deliberate transition strategy, replace weight loss targets with physical performance goals and promote sports that are appropriate for young men affected by overweight and obesity.
