An economic evaluation of chronic obstructive pulmonary disease clinical pathway in Saskatchewan, Canada: Data-driven techniques to identify cost-effectiveness among patient subgroups.

BACKGROUND: Saskatchewan has implemented care pathways for several common health conditions. To date, there has not been any cost-effectiveness evaluation of care pathways in the province. The objective of this study was to evaluate the real-world cost-effectiveness of a chronic obstructive pulmonary disease (COPD) care pathway program in Saskatchewan. METHODS: Using patient-level administrative health data, we identified adults (35+ years) with COPD diagnosis recruited into the care pathway program in Regina between April 1, 2018, and March 31, 2019 (N = 759). The control group comprised adults (35+ years) with COPD who lived in Saskatoon during the same period (N = 759). The control group was matched to the intervention group using propensity scores. Costs were calculated at the patient level. The outcome measure was the number of days patients remained without experiencing COPD exacerbation within 1-year follow-up. Both manual and data-driven policy learning approaches were used to assess heterogeneity in the cost-effectiveness by patient demographic and disease characteristics. Bootstrapping was used to quantify uncertainty in the results. RESULTS: In the overall sample, the estimates indicate that the COPD care pathway was not cost-effective using the willingness to pay (WTP) threshold values in the range of $1,000 and $5,000/exacerbation day averted. The manual subgroup analyses show the COPD care pathway was dominant among patients with comorbidities and among patients aged 65 years or younger at the WTP threshold of $2000/exacerbation day averted. Although similar profiles as those identified in the manual subgroup analyses were confirmed, the data-driven policy learning approach suggests more nuanced demographic and disease profiles that the care pathway would be most appropriate for. CONCLUSIONS: Both manual subgroup analysis and data-driven policy learning approach showed that the COPD care pathway consistently produced cost savings and better health outcomes among patients with comorbidities or among those relatively younger. The care pathway was not cost-effective in the entire sample.

Clinical Diagnosis and Laboratory Testing of Abnormal Appearing Toenails: A Retrospective Assessment of Confirmatory Testing for Onychomycosis in the United States, 2022-2023.

Onychomycosis is an under-recognized healthcare burden. Despite the risk of misdiagnosis, confirmatory laboratory testing is under-utilized. Histopathologic examination with polymerase chain reaction (PCR) is currently the most effective diagnostic method; it offers direct detection and identification of a fungal invasion. In this retrospective cohort study, we assessed confirmatory testing results, with matching clinical diagnoses, in 96,293 nail specimens submitted during a 9-month period from 2022 to 2023. Toenail specimens were examined using fungal culture, histopathology and/or PCR. Clinical diagnoses were identified using the International Classification of Diseases 10th Revision codes. For clinically diagnosed onychomycosis patients, the overall positivity rate was 59.4%; a similar positivity rate (59.5%) was found in patients with clinically diagnosed non-fungal nail dystrophy. Performing a histopathologic examination with PCR was more likely to provide pathogen identification results than using fungal culture. Male patients had a higher rate of onychomycosis overall; however, female patients had more non-dermatophyte mold onychomycosis caused by Aspergillus. Clinically diagnosed onychomycosis patients with a co-diagnosis of tinea pedis were more likely to test positive for onychomycosis by PCR (odds ratio [OR]: 4.2; 95% confidence interval [CI]: 2.7-6.4), histopathology (OR: 2.5; 95% CI: 2.0-3.1) and fungal culture (OR: 3.2; 95% CI: 1.5-6.6). Our results support the use of confirmatory laboratory testing when there is a clinical diagnosis of onychomycosis.

Real-World Cost-Consequence Analysis of an Integrated Chronic Disease Management Program in Saskatchewan, Canada.

An integrated disease management program otherwise called a clinical pathway was recently implemented in Saskatchewan, Canada for patients living with chronic obstructive pulmonary disease (COPD). This study compared the real-world costs and consequences of the COPD clinical pathway program with 2 control treatment programs. The study comprised adult COPD patients in Regina (clinical pathway group, N = 759) matched on propensity scores to 2 independent control groups of similar adults in (1) Regina (historical controls, N = 759) and (2) Saskatoon (contemporaneous controls, N = 759). The study measures included patient-level healthcare costs and acute COPD exacerbation outcomes, both tracked in population-based administrative health data over a one-year follow-up period. Analyses included Cox proportional hazards models and differences in means between groups. The bias-corrected and accelerated bootstrap method was used to calculate 95% confidence intervals (CI). The COPD pathway patients had lower risks of moderate (hazard ratio [HR] =0.57, 95% CI [0.40-0.83]) and severe (HR = 0.43, 95% CI [0.28-0.66]) exacerbations compared to the historical control group, but similar risks compared with the contemporaneous control group. The COPD pathway patients experienced fewer episodes of exacerbations compared with the historical control group (mean difference = -0.30, 95% CI [-0.40, -0.20]) and the contemporaneous control group (mean difference = -0.12, 95% CI [-0.20, -0.03]). Average annual healthcare costs in Canadian dollars were marginally higher among patients in the COPD clinical pathway (mean = $10 549, standard deviation [SD] =$18 149) than those in the contemporaneous control group ($8841, SD = $17 120), but comparable to the historical control group ($10 677, SD = $21 201). The COPD pathway provides better outcomes at about the same costs when compared to the historical controls, but only slightly better outcomes and at a marginally higher cost when compared to the contemporaneous controls.

A comprehensive review of nondermatophyte mould onychomycosis: Epidemiology, diagnosis and management.

Nondermatophyte moulds (NDMs) are widely distributed and can be detected in association with mycotic nails; however, sometimes it can be challenging to establish the role of NDMs in the pathogenesis of onychomycosis (i.e. causative vs. contaminant). In studies where the ongoing invasive presence of NDMs is confirmed through repeat cultures, the global prevalence of NDMs in onychomycosis patients is estimated at 6.9% with the 3 most common genus being: Aspergillus, Scopulariopsis and Fusarium. NDM onychomycosis can, in many cases, appear clinically indistinguishable from dermatophyte onychomycosis. Clinical features suggestive of NDMs include proximal subungual onychomycosis with paronychia associated with Aspergillus spp., Fusarium spp. and Scopulariopsis brevicaulis, as well as superficial white onychomycosis in a deep and diffused pattern associated with Aspergillus and Fusarium. Longitudinal streaks seen in patients with distal and lateral onychomycosis may serve as an additional indicator. For diagnosis, light microscopic examination should demonstrate fungal filaments consistent with an NDM with at least two independent isolations in the absence of a dermatophyte; the advent of molecular testing combined with histological assessment may serve as an alternative with improved sensitivity and turnover time. In most instances, antifungal susceptibility testing has limited value. Information on effective treatments for NDM onychomycosis is relatively scarce, unlike the situation in the study of dermatophyte onychomycosis. Terbinafine and itraconazole therapy (continuous and pulsed) appear effective to varying extents for treating onychomycosis caused by Aspergillus, Fusarium or Scopulariopsis. There is scant literature on oral treatments for Neoscytalidium.

Impacts of Chronic Obstructive Pulmonary Disease Care Pathway on Healthcare Utilization and Costs: A Matched Multiple Control Cohort Study in Saskatchewan, Canada.

OBJECTIVES: This study aimed to evaluate the real-world impacts of a chronic obstructive pulmonary disease (COPD) care pathway program on healthcare utilization and costs in Saskatchewan, Canada. METHODS: A difference-in-differences evaluation of a real-life deployment of a COPD care pathway, using patient-level administrative health data in Saskatchewan, was conducted. The intervention group (n = 759) included adults (35+ years) with spirometry-confirmed COPD diagnosis recruited into the care pathway program in Regina between April 1, 2018 and March 31, 2019. The 2 control groups comprised adults (35+ years) with COPD who lived in Saskatoon during the same period (n = 759) or Regina between April 1, 2015 and March 31, 2016 (n = 759) who did not participate in the care pathway. RESULTS: Compared with the individuals in the Saskatoon control groups, individuals in the COPD care pathway group had shorter inpatient hospital length of stay (average treatment effect on the treated [ATT] -0.46, 95% CI -0.88 to -0.04) but a higher number of general practitioner visits (ATT 1.46, 95% CI 1.14 to 1.79) and specialist physician visits (ATT 0.84, 95% CI 0.61 to 1.07). Regarding healthcare costs, individuals in the care pathway group had higher COPD-related specialist visit costs (ATT $81.70, 95% CI $59.45 to $103.96) but lower COPD-related outpatient drug dispensation costs (ATT -$4.81, 95% CI -$9.34 to -$0.27). CONCLUSIONS: The care pathway reduced inpatient hospital length of stay, but increased general practitioner and specialist physician visits for COPD-related services within the first year of implementation.

Utility of polymerase chain reaction for assessment of onychomycosis during topical therapy.

BACKGROUND: Increased detection of fungi including non-dermatophyte molds (NDMs) using polymerase chain reaction (PCR) methods is well-established. However, the use of PCR to evaluate ongoing onychomycosis treatment outcome has not been investigated. METHODS: Nail samples from 28 patients receiving topical efinaconazole were evaluated by both KOH/culture and PCR methods across the study period. Detection of microorganisms by PCR was compared to the culture at baseline and end of study at month 24 (M24). Fungal detection by both methods was evaluated with respect to clinical cure observed as 100% visual clearance of the target toenail. RESULTS: By culture, all 28 subjects were dermatophyte-positive at pre-treatment; only 4/28 also exhibited an NDM microorganism. According to PCR, 24/28 subjects were dermatophyte-positive pre-treatment, with 25/28 also exhibiting NDMs. At M24, 18/28 (64.3%) participants had negative KOH/culture results, in contrast to 4/28 (14.3%) negative PCR results. PCR showed higher rates of NDM detection than the culture at baseline as well as M24. Calculations to compare the diagnostic utility of KOH/culture versus PCR found that positive tests with both methods reliably indicate the presence of onychomycosis, but negative PCR correlated better with onychomycosis cure than did KOH/culture. DISCUSSION: PCR confirmed a high presence of NDMs pre-treatment, and continued presence of NDMs to M24, with unknown significance requiring further investigation. Though both KOH/culture and PCR have diagnostic limitations, PCR showed better overall utility than culture in predicting onychomycosis topical treatment outcome and should be more strongly considered for evaluation of topical therapies.

Culturally Responsive Supports for Metis Elders and Metis Family Caregivers.

Malgré une attention académique considérable au rôle de la famille des soignants avec la population générale, peu de recherches ont été menées avec les familles autochtones. Cette étude qualitative vise à combler cette lacune en se concentrant sur l'expérience des soignants Metis, fournir des soins aux adultes Metis plus âges. Des groupes de discussions et des entrevues ont été menés avec des aidants familiaux Metis (n - 79), aînés Metis (n - 11), et soignants officiels (n - 8). Bien qu'il existe de parallèles considérables dans les expériences des soins identifiés dans cette étude sur les Metis avec celles déjà documentées dans la littérature, il existe néanmoins des différences importantes pour la prestation des soins culturellement adaptés aux aînés Metis.Despite considerable academic attention to the role of family caregivers within the general population, little research has been conducted with Indigenous families. This qualitative study aims to fill that gap by focusing on the experiences of Metis caregivers providing care for older Metis adults. Focus groups and interviews were conducted with Metis family caregivers (n = 79), Metis Elders (n = 11) and formal caregivers (n = 8). Although there are considerable parallels in the caregiving experiences identified in this Metis study with those already documented in the literature, there are nonetheless important differences for providing culturally responsive care to Metis seniors.

Creative Strengths-Based Approaches to Health Promotion: Perspectives From Graduate Training Experiences.

The authors met during a career development experience where they discussed the commonalities of their successes and challenges conducting creative strengths-based health promotion research with underserved communities during their graduate and postgraduate training. They identified changes to health promotion pedagogy that they would like to see in the future. These include understanding both the strengths and the challenges of creative strengths-based health promotion research conducted with underserved communities, ensuring that reflexivity and flexibility is a component of the process, developing support networks for trainees, understanding personal limitations to effect change, and supporting self-care. They hope that trainees and health education programs will learn from their experiences.

"There is always a better way": Managing uncertainty in decision making about new cancer drugs in Canada.

Policy decisions about the approval and funding of new cancer drugs must often be made in an environment of complex uncertainty about clinical and cost-effectiveness data. The focus of this article is on the results from qualitative interviews with senior officials (n = 16) who make decisions about or influence cancer drug policy in various organizations in the Canadian cancer control system. Most participants identified the use of a limited number of informal approaches to address uncertainty, such as grounding decisions in evidence and advice from expert groups. People tended to focus on evidence informed decisions including price negotiations, the ability to implement policy changes, and stakeholder values. Lessons from the Canadian context related to continuing efforts to build a public culture of understanding into how policy decisions like cancer drug funding are made may result in greater acceptance and increased confidence in health policy decision-making processes across multiple sectors internationally.

Prevalence and Risk Factors for Infections in a Pregnant Adolescent Population.

STUDY OBJECTIVE: Our objective was to identify risk factors associated with maternal infections and placental inflammation in pregnant adolescents attending an urban adolescent maternity clinic. DESIGN: This cross-sectional, descriptive study used survey and medical chart data collected at entry and prospectively across gestation. The prevalence of maternal infections and placental inflammation was determined and potential risk factors were identified. SETTING: Rochester Adolescent Maternal Program (RAMP) in Rochester, NY. PARTICIPANTS: Racially and ethnically diverse pregnant adolescents (n = 158 ≤ 18 y at entry) were recruited. INTERVENTIONS AND MAIN OUTCOME MEASURES: Main outcome measures were diagnosis of an infection or inflammatory condition in relation to demographic, anthropometric, dietary, socioeconomic, and health data. RESULTS: The three most prevalent infections diagnosed in this study population were recto-vaginal colonization of group B Streptococcus (GBS) (38%), bacterial vaginosis (BV) (40%) and candida (42%). African-American teens (AOR = 4.6; 95% CI: 1.74-13.02) and those with higher pre-pregnancy BMI (ppBMI; AOR = 1.2; 95% CI: 1.04-1.31) were more likely to test positive for BV across gestation. Older maternal age decreased the likelihood of positive tests for trichomoniasis (OR = 0.51; 95% CI: 0.26-0.92) and gonorrhea (OR = 0.38; 95% CI: 0.16-0.82). Higher mean dietary vitamin D intake (mcg/d) was associated with a lower likelihood of testing positive for recto-vaginal GBS (OR = 0.87; 95% CI: 0.77-0.98). CONCLUSION: Addressing modifiable risk factors associated with dietary intake and pre-pregnancy weight may help reduce health disparities among pregnant minority adolescents. Additionally, targeted sexual health education may greatly benefit younger female adolescents.

Maternal inflammation at delivery affects assessment of maternal iron status.

Pregnant adolescents (aged ≤ 18 y, n = 253) were followed from ≥ 12 wk of gestation to delivery to assess longitudinal changes in anemia and iron status and to explore associations between iron status indicators, hepcidin, and inflammatory markers. Hemoglobin, soluble transferrin receptor (sTfR), ferritin, serum iron, erythropoietin (EPO), hepcidin, C-reactive protein, interleukin-6 (IL-6), folate, and vitamin B-12 were measured, and total body iron (TBI) (milligrams per kilogram) was calculated using sTfR and ferritin values. Anemia prevalence increased from trimesters 1 and 2 (3-5%, <28 wk) to trimester 3 (25%, 33.2 ± 3.7 wk, P < 0.0001). The prevalence of iron deficiency (sTfR > 8.5 mg/L) doubled from pregnancy to delivery (7% to 14%, P = 0.04). Ferritin and hepcidin concentrations at delivery may have been elevated as a consequence of inflammation because IL-6 concentrations at delivery were 1.6-fold higher than those obtained at 26.1 ± 3.3 wk of gestation (P < 0.0001), and a positive association was found between IL-6 and both hepcidin and ferritin at delivery (P < 0.01). EPO was consistently correlated with hemoglobin (r = -0.36 and -0.43, P < 0.001), ferritin (r = -0.37 and -0.32, P < 0.0001), sTfR (r = 0.35 and 0.25, P < 0.001), TBI (r = -0.44 and -0.37, P < 0.0001), and serum iron (r = -0.22 and -0.16, P < 0.05) at mid-gestation and at delivery, respectively. EPO alone explained the largest proportion of variance in hemoglobin at 26.0 ± 3.3 wk of gestation (R(2) = 0.13, P = 0.0001, n = 113) and at delivery (R(2) = 0.19, P < 0.0001, n = 192). Pregnant adolescents are at high risk of anemia. EPO is a sensitive indicator of iron status across gestation, is not affected by systemic inflammation, and may better predict risk of anemia at term. The trial was registered at clinicaltrials.gov as NCT01019902.

A spotlight on strategies for increasing safety reporting in nursing education.

Health care policy changes have ripple effects that touch many different areas of the health care arena. Quality and safety are at the forefront of this discussion. In health care institutions, error reporting is expected to monitor and improve patient safety. Procedures are in place for reporting errors. However, multiple barriers lead to low use of reporting methods. Creating a reporting system that leads to transparency could positively affect the health care system. Introducing nurses to error reporting at the beginning of their educational experience could lead to a reduction in barriers to error reporting and promote error reporting. This article discusses strategies to increase error and near-miss reporting in a school of nursing.

Rural maternity care services under stress: the experiences of providers.

INTRODUCTION: Between 2000 and 2004, 17 small rural maternity care services in British Columbia (BC) closed or were placed under moratoria. This paper explores the experiences of care providers in 4 rural BC communities that have lost or are at risk of losing their local maternity services. METHODS: We conducted qualitative, semistructured interviews and focus groups with 27 health care providers (doctors and nurses) and 3 administrators. The analysis used modified grounded theory. We chose 4 rural communities to include a diversity of characteristics, including community size, geography, distance to the nearest hospital capable of performing cesarean section, and cultural and ethnic subpopulations. RESULTS: Care providers identified significant stressors related to the provision of maternity care services, including the development and maintenance of competency in the context of decreasing birth volume, the safety of local maternity care without cesarean section and the desire to balance women's needs with the realities of rural practice. CONCLUSIONS: Maternity care providers in small rural communities are experiencing stress due in part to the absence of evidence-based policy and planning for rural maternity care services. This stress may contribute to challenges in the retention of rural maternity care providers, thus risking the future of small rural maternity services.
