Fast-Track in Minimally Invasive Gynecology: A Randomized Trial Comparing Costs and Clinical Outcomes

Study Objective: Evaluate the effects of a fast-track (FT) protocol on costs and post-operative recovery.Methods: One hundred and seventy women undergoing total laparoscopic hysterectomy for a benign indication were randomized in a FT protocol or a usual care protocol. A FT protocol included the combination of minimally invasive surgery, analgesia optimization, early oral refeeding and rapid mobilization of patients was compared to a usual care protocol. Primary outcome was costs. Secondary outcomes were length of stay, post-operative morbidity and patient satisfaction.Main Results: The mean total cost in the FT group was 13,070 ± 4,321 Euros (EUR) per patient, and that in the usual care group was 3.5% higher at 13,527 ± 3,925 EUR (p = 0.49). The FT group had lower inpatient surgical costs but higher total ambulatory costs during the first post-operative month. The mean hospital stay in the FT group was 52.7 ± 26.8 h, and that in the usual care group was 20% higher at 65.8 ± 33.7 h (p = 0.006). Morbidity during the first post-operative month was not significantly different between the two groups. On their day of discharge, the proportion of patients satisfied with pain management was similar in both groups [83% in FT and 78% in the usual care group (p = 0.57)]. Satisfaction with medical follow-up 1 month after surgery was also similar [91% in FT and 88% in the usual care group (p = 0.69)].Conclusion: Implementation of a FT protocol in laparoscopic hysterectomy for benign indications has minimal non-significant effects on costs but significantly reduces hospital stay without increasing post-operative morbidity nor decreasing patient satisfaction.Clinical Trial Registration:www.ClinicalTrials.gov, identifier: NCT04839263.

Background:Western countries experience an increasing demand for care, particularly for inflammatory arthritis (IA), while the healthcare budget decreases1. The innovative value-based primary care strategy2includes integrated care networks, where primary and secondary care bundle their expertise to improve patient value by providing the right care at the right place.General practitioners (GPs) have difficulties recognising IA, leading up to only 20% IA diagnoses of all newly referred arthralgia patients. However, since IA needs to be treated as early as possible to overcome progression, it is worthwhile to analyse whether integrated care networks have an impact on patient outcomes and cost-effectiveness. Triage by a rheumatologist in a primary care setting is one of the most promising integrated care networks for efficient referrals3.Objectives:To assess the effect of triage by a rheumatologist in a primary care setting in patients suspect for inflammatory arthritis.Methods:The present study follows a cluster randomized controlled trial design. The intervention, triage by a rheumatologist in a local primary care centre, will be compared to usual care. Usual care means that patients are referred to a rheumatology outpatient clinic based on the opinion of the general practitioner.The primary outcome is the frequency of IA diagnoses assessed by a rheumatologist. Patient reported outcome measures (PROMs (EQ-5D)) and costs (work productivity (iPCQ) and healthcare utilization (iMCQ)) were determined at baseline, after three, six and twelve months. The target was to include 267 patients for each study group (power level 0.8). Since this study is still ongoing we can only show first results on the efficiency of referrals.Results:In the period between February 2017 and December 2019 a total of 543 participants were included; 275 in the usual care group and 268 in the triage group. Mean age (51.3 ± 14.6 years) and percentage of men (23.6%) were comparable between groups (page=0.139; psex=0.330).The preliminary data show that the number of referred patients in the triage group is n=28 (10.5%) (Fig. 1). 32 patients (11.9%) were not referred directly but advice was given for additional diagnostics. Since all patients in the usual care group were referred there is a decrease of at least 77.6% in referrals when rheumatologists are participating in the integrated practice units.Preliminary data on diagnosis are available for all referred patients in the triage group and for n=137 (49.8%) in the usual care group at this point. In the triage group n=18 (64.2%) of referred patients were diagnosed with IA (6.7% of the total study population). In the usual care group this was n=52 (38.0%) of the patients yet diagnosed.Conclusion:These preliminary results of an integrated care network are promising. Approximately three-quarters of all patients can be withheld from expensive outpatient care. PROMs data and cost-effectiveness analysis will give clear answers in order to provide evidence whether this integrated care network can be implemented as a standard of care.References:[1] Rijksoverheid.

Inpatient Database

It is unclear when to begin rehabilitation after coronary artery bypass grafting (CABG) in the intensive care unit (ICU). Using the Japanese Diagnosis Procedure Combination inpatient database from 2010 to 2018, we identified adult patients who underwent a CABG and who were admitted to the ICU for ≥3 consecutive days from the date of their CABG. Patients who started any rehabilitation program prescribed by physicians or therapists within 3 days of CABG were defined as the early rehabilitation group, and the remaining patients were defined as the usual care group. We identified 30,568 eligible patients, with 13,150 (43%) patients in the early rehabilitation group. An inverse probability of treatment weighting analyses showed that the Barthel Index score at discharge in the early rehabilitation group was significantly higher than that in the usual care group (difference: 3.2; 95% confidence interval: 1.5–4.8). The early rehabilitation group had significantly lower in-hospital mortality, total hospitalization costs, length of ICU stay, and hospital stay vs. the usual care group. Our results suggested that early rehabilitation by physicians or therapists beginning within 3 days of CABG was safe, as suggested by the low mortality and improved physical function in patients who underwent CABG.

Abstract Background Green care farms, which offer care for people with dementia in a farm setting, have been emerging in the Netherlands. The aim of this study was to 1) implement green care farms which use rice farming in Japan, 2) explore the positive experiences of rice farming care, and 3) compare the effect of rice farming care to that of usual care on well-being and cognitive ability. Methods We developed a new method of green care farm in Japan which uses rice farming, a farming that is practiced all over East Asia. The participants were 15 people with dementia (mean age = 75.6 ± 9.8 years) who participated in a one-hour rice farming care program once a week for 25 weeks. We also collected qualitative data on the positive experiences of study participants after the program. As a reference data, we also collected the corresponding data of the usual care group which included 14 people with dementia (mean age = 79.9 ± 5.8 years) who were attending the near-by day-care. Results The mean participation rate on the rice farming care group was 72.1%. After the intervention, participants reported experiencing enjoyment and connection during the program. It also changed the staff’s view on dementia. The green care farm group showed a significant improvement in well-being but no significant difference in cognitive function compared to the usual care group. Conclusions Green care farms by using rice farming is promising care method which is evidence-based, empowerment-oriented, strengths-based, community-based dementia service, which also delivers meaningful experience for the people with dementia in East Asia.

Clinic Visits

BACKGROUND Adhering to prescribed medical interventions predicts the efficacy of the treatment. In the physical health clinics, not adhering to prescribed therapy can take the form of not attending a scheduled clinic visit (no-show appointment) or prematurely terminating treatment against the advice of the provider (self-discharge). A variety of interventions, including mobile phone apps have been introduced with patients to increase their adherence with attending scheduled clinic visits. Limited research has examined the impact of a mobile phone app among patients attending a chiropractic and rehabilitation clinic visits. OBJECTIVE The purpose of this study was to compare adherence with prescribed physical health treatment among patients attending a chiropractic and rehabilitation clinic who did and did not choose to adopt a phone-based app to complement their treatment. METHODS The medical records of new patients who presented for care during 2019 and 2020 at five community-based chiropractic and rehabilitation clinics were reviewed for the number of kept and no-show appointments and if the patient was provider discharged or self-discharged. During this 24-month study 36.3% of the 4,126 patients seen in the targeted clinics had downloaded the Kanvas App to their mobile phone while the remaining patients chose not to download the app (Usual Care Group). The gamification component of the Kanvas app provided the patient with a point every time they attended their visits which could be redeemed for an incentive. RESULTS During both 2019 and 2020 respectively the Kanvas App Group (50%-38%) were provider discharged at a greater rate than the Usual-Care group (47-31%). The Kanvas App Group kept a similar number of appointments compared to the Usual-Care Group in 2019 (10.20 vs. 8.68) but kept significantly more appointments than the Usual-Care Group in 2020 (11.63 vs. 7.67). During 2019 both groups exhibited a similar number of no-show appointments (1.89 vs 1.96) but in 2020 the Kanvas App Group demonstrated more no-show appointments (2.89 vs 2.14) than the Usual Care. When collapsed across years and self discharged the Kanvas App group had a greater number of kept appointments (7.79) compared to the Usual Care group (4.58). When provider discharged both groups exhibited a similar number of kept appointments (15.25 vs 13.82). The Kanvas App group (1.38) and the Usual Care group (1.34) were similar in the number of no-show appointments when provider discharged and when self-discharged the Kanvas App Group had more no-show appointments (3.37) compared to the Usual Care Group (2.44). CONCLUSIONS When patients were provider discharged, they exhibited a similar number of kept appointments and no-show appointment. When subjects were self-discharged and received the Kanvas App they exhibited 3.2 more kept appointments and .94 more no-show appointments than self-discharged Usual Care group.

BACKGROUND Malnutrition is the most common problem in congenital heart diseases patients. Health based mobile applications play an important role in planning and tracking of diet for better nutritional status OBJECTIVE To assess the effect of artificial intelligence on nutritional status of children post cardiac surgery in comparison to usual care group. To assess usefulness of diet related mobile application in comparison to usual care group. METHODS This is a two arm randomized controlled trial that was conducted at a Tertiary Care Hospital, Rawalpindi. The study duration was 6 months from February 2021 till July 2021. Sample size was calculated to be 88. Intervention group was given a diet related mobile application and usual care group was handed a pamphlet with diet instructions on discharge. RESULTS Mean weight of all participants was 15 ± 5.7 kg at the time of discharge whereas at the end of 8th week mean weight of the participants in usual care group was 16.5 ± 7.2 kg and intervention group was 17.1 ± 5 kg. Average calories consumed by usual care group was 972 ± 252 kcal and 1000.75 ± 210 kcal by intervention group after 8 weeks of discharge. Average proteins consumed by the usual care group was 34.3 ± 12.5 grams and 39± 6.4 grams by intervention group after 8 weeks of discharge. At the end of intervention preferred diet planning tool for 79% of the participants was mobile application. At 8th week 93% of the participants considered the visual cues useful, 80% think that the mobile application language was understandable, 79% of the participants think nutritional goal setting is a useful feature in mobile application and 55% of the participants think the recipes in the application were useful. CONCLUSIONS The study showed strength for the future of scalable modern technology for self-nutrition monitoring. There was slight increase in the weight and nutritional intake of both groups as interventions period was limited.

Abstract Aim of the Work to provide cumulative data about the efficacy and safety of neuro-muscular electrical stimulation (NMES) combined with usual care (UC) versus usual care alone in ICU patients with Critical Illness Myopathy (CIM). Methodology The current systematic review was done on studies published between 2009 and 2019. The total number of patients in all the included studies was 1259 patients; 652 in NMES group, and 607 in UC group. Our data were divided into two groups: NMES (652 patients), and UC (607 patients). Metaanalysis study was done on 11 studies which described and compared the 2 different techniques for treatment of CIM; with overall number of patients (N = 1259). Results Regarding 1ry outcome measures, we found 8 studies reported critical Critical illness myopathy (CIM), critical illness polyneuropathy (CIP), and the overlap, critical care setting MRC scale for muscle strength, with total number of patients (N = 968). The random-effects model of the meta-analysis study showed non-significant difference in mean MRC scale in NMES group compared to usual care group (p > 0.05). We also found 11 studies reported ICU stay with total number of patients (N = 1259). The random-effects model of the meta-analysis study showed nonsignificant difference in mean ICU stay in NMES group compared to usual care group (p > 0.05). We also found only 2 studies reported SF-36 scale for quality of life, with total number of patients (N = 270). The fixed-effects model of the metaanalysis study showed highly significant decrease in mean SF-36 scale in NMES group compared to usual care group (p = 0.003). Regarding 2ry outcome measure, we found 3 studies reported CIM incidence with total number of patients (N = 394). The fixed-effects model of the meta-analysis study showed marked decrease in CIM incidence in NMES group compared to usual care group, but not reaching statistical significance (p > 0.05). We also found 9 studies reported mortality rate with total number of patients (N = 1044). The fixed-effects model of the meta-analysis study showed non-significant difference in mortality rate in NMES group compared to usual care. Our systematic review and meta-analysis showed that NMES combined with usual care was not associated with significant differences in global muscle strength, ICU stay, quality of life score, CIM incidence and mortality rate in comparison with usual care alone in critically ill patients. Conclusion NMES is not superior to usual care in management of CIM. Usual care remains the mainstay of management of CIM with significant better outcomes, in addition to preventive measures as early aggressive treatment of sepsis and MOF, blood glucose control, optimizing certain drugs use, early enteral nutrition, maintaining water, electrolyte and acidbase balance.

Objective. The aim of this study was to evaluate the cost effectiveness of a mobile-based intervention for patients with type 2 diabetes mellitus (T2DM) and compare it with the usual management mode. Method. A total of 215 patients with T2DM in a tertiary-care hospital specific to diabetes were selected as the study population. This study was conducted from January 1, 2019 to January 1, 2020. Of the 215 patients, 130 were randomly assigned to the mHealth group and 85 were assigned to the usual care group. IBM SPSS 25.0 software was used for descriptive statistics, t tests, chi-square tests, and correlation analyses. Haemoglobin A1c (HbA1c) was the effectiveness parameter adopted. Cost-effectiveness analyses were performed, and incremental cost-effectiveness ratios (ICERs) were calculated. Results. Of the 215 patients with T2DM, the proportion of male patients was 66.0%. The mean age of the patients was 47.2 (SD 9.95). Differences in baseline information were not statistically significant between the two groups ( P > 0.05 ). At the 3-, 6-, and 12-month follow-ups, the mHealth group reported higher control rates of HbA1c than the usual care group, 67.9% versus 46.2% ( P < 0.001 ), 72.4% versus 45.4% ( P < 0.001 ), and 74.6% versus 47.1% ( P < 0.001 ), respectively. The value of HbA1c was positively related to total patient cost, material fee, Western medicine fee, and hospitalization expenses ( P < 0.05 ), with correlation coefficients of 0.202, 0.200, 0.172, and 0.183, respectively. The costs of the mHealth group and usual care group were CNY¥ 1169.76 and CNY¥ 1775.44 per patient/year, respectively. The incremental cost of the mHealth intervention was CNY¥ −605.68 per patient/year. The ICER was CNY¥ −22.02 per patient/year. Conclusion. Compared with the usual care mode, the mHealth management model for patients with T2DM improved the control rate of HbA1c, and the mHealth management mode had better cost effectiveness.

Introduction: Many barriers exist to integrating smoking cessation into delivery of lung cancer screening including limited provider time and patient misconceptions.Aims: To demonstrate that proactive outreach from a telephone counsellor outside of the patient's usual care team is feasible and acceptable to patients.Methods: Smokers undergoing lung cancer screening were approached for a telephone counselling study. Patients agreeing to participate in the intervention (n = 27) received two telephone counselling sessions. A 30-day follow-up evaluation was conducted, which also included screening participants receiving usual care (n = 56).Results/Findings: Most (89%) intervention participants reported being satisfied with the proactive calls, and 81% reported the sessions were helpful. Use of behavioural cessation support programs in the intervention group was four times higher (44%) compared to the usual care group (11%); Relative Risk (RR) = 4.1; 95% CI: 1.7 to 9.9), and seven-day abstinence in the intervention group was double (19%) compared to the usual care group (7%); RR = 2.6; 95% CI: 0.8 to 8.9).Conclusions: This practical telephone-based approach, which included risk messages clarifying continued risks of smoking in the context of screening results, suggests such messaging can boost utilisation of evidence-based tobacco treatment, self-efficacy, and potentially increase the likelihood of successful quitting.

Purpose: To develop an education program for nurses specializing in dementia care, and to investigate its effects. Methods: An intervention study of nurses was conducted using a quasi-experiment with 3 randomly assigned groups. Participants were 51 nurses from a psychiatric hospital dementia ward, divided into an intervention program group (17 nurses), a knowledge-acquisition-only group (16 nurses), and a usual-care group (18 nurses) as controls. The program group intervention comprised 3 frameworks: motivation for achieving the task, acquisition of professional knowledge required for dementia care, and sharing of successful experiences based on professional knowledge. The knowledge-acquisition-only group received only the acquisition of professional knowledge framework, and the usual-care group received only the usual-care framework. The intervention period was 3 months. Results: Post-intervention, the program group had a significantly greater sense of self-efficacy associated with professional knowledge and significantly greater self-efficacy associated with practice compared with the knowledge-acquisition-only and the usual-care groups. Professional knowledge was acquired by 80% of the program group, compared with 70% of the knowledge-acquisition-only group. A co-occurrence network diagram of the multivariate analysis results produced by text mining of the descriptive data indicated that nurses provided care for symptoms specific to different diseases based on their pathological mechanisms. Conclusion: Program implementation led to the acquisition of deeper knowledge and greater self-efficacy by sharing expertise-based practices and successful experiences, compared with desk-based learning in a single workshop lecture, suggesting the program’s usefulness in clinical practice.

Background: The Conventus Distal Radius System (DRS) is an intramedullary fixation scaffold inserted into the lateral aspect of the distal radius. The purpose of this study was to identify insertion site anatomy to illustrate risks associated with the minimally invasive nature of radial-sided implant application. Methods: Ten cadavers were utilized. Using fluoroscopy, the 1.1-mm Kirschner wire and template was introduced per manufacturer’s guidelines, access guide assembled, and dissection carried out to the superficial radial nerve (SRN) with preservation of the native location. The access guide marked the insertion location for the side-cut drill. This point was measured in relationship to structures nearby, including the SRN, brachioradialis (BR), lateral antebrachial cutaneous nerve (LABCN), and radial styloid (RS). Results: The large guide contacted the SRN in 4 of 10 cadavers and was volar to it in 6 of 10. When volar, the mean distance was 1.7 mm. The tip of the RS to the large access guide averaged 44.5 mm. The small guide contacted the SRN in 2 of 10, was volar to it in 4 of 10, and between the bifurcation in 4 of 10. When volar, the distance averaged 3.25 mm. When bifurcated, the distance from the small guide to both the dorsal and volar branches was 3.5 mm. The distance from the RS to the small guide averaged 37.8 mm. The LABCN was found in the field of dissection in 4 of 10 cadavers. Conclusions: Several structures are at risk during insertion of the Conventus DRS; thus, knowledge of the relevant anatomy of this minimally invasive approach is crucial to optimize outcomes and patient satisfaction, and to avoid nerve injury.
