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.

Empowering Underserved Communities in Southern Puerto Rico: A Formal Training Program in Community Health Promotion.

Community health promotion offers a potential solution to persistent healthcare challenges, with community health workers playing a pivotal role. The Community Training Institute for Health Disparities (CTIHD) implemented a problem-solving curriculum in Community Health Promotion, integrating a competency-based learning model through two courses: Introduction to Community Health Promotion and Design of an Action Plan for the Promotion of Community Health. Each course comprised ten three-hour sessions, featuring pre/post-tests, evaluations, and a cognitive debriefing. Knowledge change was assessed using pre/post-test scores among 27 community leaders from southern Puerto Rico. Cohort 1 and Cohort 2 demonstrated an overall retention rate of 62.6% and 96.7%, respectively. Although differences in knowledge gained between cohorts and courses weren't statistically significant, a trend toward increased knowledge was noted. Cohort 1 experienced a 22% knowledge increase in Course 1 and a 24% increase in Course 2. Cohort 2 demonstrated a 41% knowledge increase in Course 1 and a 25% increase in Course 2. The CTIHD's Community Health Promotion Program has made significant strides in elevating awareness and knowledge, marking a positive step toward reducing health disparities and fostering healthier, empowered communities in southern Puerto Rico.

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.

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.

Assessing Acceptability, Feasibility, and Preliminary Effectiveness of a Community-Based Participatory Research Curriculum for Community Members: A Contribution to the Development of a Community-Academia Research Partnership.

Purpose: The community-based participatory research approach has been identified as a great asset in reducing health disparities through the integration of community members in all phases of the research process. It is essential to provide skills to community members to achieve successful research partnerships. The purpose of this study is to evaluate the feasibility, acceptability, and preliminary efficacy of the community-based participatory research training curriculum for community members. Methods: Using mixed-methods, noncomparative design, eight workshops were developed and tested. Workshops covered topics such as community-based participatory research principles, health disparities, ethics in community-based participatory research, and fundamentals of research methodology. A total of 25 community leaders were trained. Pre-/post-test knowledge (unpaired t-test), retention rate, workshop satisfaction, and cognitive debriefing sessions were used to assess knowledge gained and acceptability and feasibility of the curriculum. Results: A retention rate of 100% and an average satisfaction of 92.68% were obtained. Preliminary effectiveness results indicate that there was an overall significant change in participant's knowledge before and after the curriculum (p<0.001). In the cognitive debriefing, participants were satisfied with the organization and structure and found the curriculum feasible. Furthermore, participants identified the skills acquired to aid in being more effective in their communities and work with academic researchers. The following changes were recommended: workshops' order, time, practical activities, and level of language. Discussion: Findings from this study suggest that the curriculum was acceptable and feasible to community leaders and that it might provide skills to actively incorporate community members in research activities. A large randomized clinical trial (RCT) study to evaluate curriculum effectiveness is recommended.

Pre-travel preparation for Cusco, Peru: a comparison between European and North American travelers.

BACKGROUND: Demographics, preferences on health care, and regional differences in pre-travel advice guidelines may influence the preparation of travelers to developing countries. METHODS: A secondary data analysis of the database of a travelers' health survey conducted in Cusco in 2002 was performed. Data from those whose place of residence was North America or Western Europe were selected. Illness rates, vaccinations, prophylactic medication use, and general recommendations on disease prevention were compared between the two groups. RESULTS: Data from 1,612 North Americans (NAM) and 3,590 Western Europeans (EUR) were analyzed. NAM were older, stayed longer in Cusco, and had less experience traveling to developing countries (p < 0.01). They reported being ill more often than EUR (58% vs 42%, p < 0.01). Diarrhea was more frequent among EUR (55.6% vs 46.7%, p < 0.01), and acute mountain sickness (AMS) was more frequent among NAM (52.8% vs 35.2%, p < 0.01). EUR sought advice from health care professionals (67.1% vs 52.0%, p < 0.01) and travel medicine practitioners (45.8% vs 37%, p < 0.01) more often. NAM used prophylactic medications more often (53% vs 48.6%, p = 0.00) and received a lower mean number of vaccines (1.97 ± 1.68 vs 2.63 ± 1.49; t-test 14.02, p < 0.01). Advice on safe sex and alcohol consumption was low in both groups, especially among NAM. CONCLUSIONS: Pre-travel preparation and travel-related illnesses varied between NAM and EUR. Improving consistency of pre-travel preparation based on the best evidence should become a priority among different national bodies providing travel medicine recommendations.

Self-reported health problems among travelers visiting Cuzco: a Peruvian Airport survey.

Travel related illnesses are a concern among travelers visiting developing countries. These illnesses affect the travelers' plans and the local tourism industry. Few data on travel related illnesses are available from tourist destinations. Foreign travelers answered a self-administered questionnaire on health issues at the departures area of Cuzcos' International Airport between August and November 2002. Self-reported travel related illnesses that occurred during the travelers stay in Cuzco were compared with demographic and risk factors. The total number of participants was 5988. Their mean age was 35.4 years (SD 11.4), and slightly over half were female. The most common countries of residence were the United States (23.5%) and the United Kingdom (20%). The median length of stay in Cuzco was 5 days (IQR: 4-7 days). Pre-travel advice was received by 93.6% of the participants. Half (47.6%) of the participants became ill while in Cuzco. The most common illnesses reported were diarrhea (49.8%), altitude sickness (43.2%), and upper respiratory infections (21.7%). Most participants who reported an illness treated themselves (75.5%), and only 22.1% sought medical attention. It is concluded that a significant burden of disease is observed in travelers to Cuzco. Self-medication is very common and apparently preferred over formal medical attention.
