A Conceptual Model for the Evaluation of Surgical Missions.

BACKGROUND: Medical missions to low and middle-income countries are increasingly frequent, with an estimated 6,000 trips sponsored by U.S. organizations accounting for approximately 200,000 surgical cases and $250 million in costs annually. However, these missions have received little critical evaluation. This paper describes the research program Operation Walk (Op-Walk) Boston, and proposes an evaluation model for similar surgical missions. METHODS: We propose an evaluation model, borrowing from the work of Donabedian and enriched by evidence from our research program. The model calls for evaluation of the salient contextual factors (culture and beliefs), system management (structure, process, and outcomes), and sustainability of the program's interventions. We used these domains to present findings from the quantitative and qualitative research work of Op-Walk Boston. RESULTS: Op-Walk's qualitative research findings demonstrated that cultural factors are important determinants of patients' perceptions of arthritis etiology, physical activity patterns, and treatment preferences. Quantitative assessments documented that Dominican patients had worse lower-extremity functional status (mean Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC] function score of 33.6) and pain preoperatively than patients undergoing total hip or knee replacement in the U.S. (WOMAC function score of 43.3 to 54), yet they achieved excellent outcomes (50-point improvement), comparable to those of their U.S. counterparts. Assessments of the quality and sustainability of the Op-Walk program showed that the quality of care provided by Op-Walk Boston meets Blue Cross Blue Shield Centers of Excellence (Blue Distinction) criteria, and that sustainable changes were transferred to the host hospital. CONCLUSIONS: Our proposed model offers a method for formal assessment of medical missions that addresses the call for evidence of their merit. We suggest that surgical missions adopt quantitative and qualitative strategies to document their impact, identify areas of improvement, and justify program continuation, growth, and support.

Postoperative Pain Management Among Dominican and American Health-Care Providers: A Qualitative Analysis.

BACKGROUND: U.S. practitioners have prescribed opioid analgesics increasingly in recent years, contributing to what has been declared an opioid epidemic by the U.S. Centers for Disease Control and Prevention (CDC). Opioids are used frequently in the preoperative and postoperative periods for patients undergoing total joint replacement in developed countries, but cross-cultural comparisons of this practice are limited. An international medical mission such as Operation Walk Boston, which provides total joint replacement to financially vulnerable patients in the Dominican Republic, offers a unique opportunity to compare postoperative pain management approaches in a developed nation and a developing nation. METHODS: We interviewed American and Dominican surgeons and nurses (n = 22) during Operation Walk Boston 2015. We used a moderator's guide with open-ended questions to inquire about postoperative pain management and factors influencing prescribing practices. Interviews were recorded and transcripts were analyzed using content analysis. RESULTS: Providers highlighted differences in the patient-provider relationship, pain medication prescribing variability, and access to medications. Dominican surgeons emphasized adherence to standardized pain protocols and employed a paternalistic model of care, and American surgeons reported prescribing variability and described shared decision-making with patients. Dominican providers described limited availability of potent opioid preparations in the Dominican Republic, in contrast to American providers, who discussed opioid accessibility in the United States. CONCLUSIONS: Our findings suggest that cross-cultural comparisons provide insight into how opioid prescribing practices, approaches to the patient-provider relationship, and medication access inform distinct pain management strategies in American and Dominican surgical settings. Integrating lessons from cross-cultural pain management studies may yield more effective pain management strategies for surgical procedures performed in the United States and abroad.

Sustainability assessment of a short-term international medical mission.

BACKGROUND: Few studies have analyzed the tangible impact of global, philanthropic medical missions. We used qualitative methods to analyze the work of one such mission, Operation Walk Boston, which has made yearly trips to a Dominican Republic hospital since 2008. METHODS: We interviewed twenty-one American and Dominican participants of the Operation Walk Boston team to investigate how the program led to changes at the host Dominican hospital and how the experience caused both mission protocols and U.S. practices to change. Transcripts were analyzed with the use of content analysis. RESULTS: Participants noted that Operation Walk Boston's technical knowledge transfer and managerial examples led to sustainable changes at the Dominican hospital. Additionally, participants observed an evolution in nursing culture, as the program inspired greater independence in decision-making. Participants also identified barriers such as language and organizational hierarchy that may limit bidirectional knowledge transfer. U.S. participants noted that their practices at home changed as a result of better appreciation for different providers' roles and for managing cost in a resource-constrained environment. CONCLUSIONS: Operation Walk Boston catalyzed sustainable changes in the Dominican hospital. Cultural norms and organizational structure are important determinants of program sustainability.

Physical activity and experience of total knee replacement in patients one to four years postsurgery in the dominican republic: a qualitative study.

OBJECTIVE: Musculoskeletal disorders are the second leading cause of years lived with disability globally. Total knee replacement (TKR) offers patients with advanced arthritis relief from pain and the opportunity to return to physical activity. We investigated the impact of TKR on physical activity for patients in a developing nation. METHODS: As part of the Operation Walk Boston surgical mission program, we interviewed 18 Dominican patients (78% women) who received TKR about their level of physical activity after surgery. Qualitative interviews were conducted in Spanish, and English transcripts were analyzed using content analysis. RESULTS: Most patients found that TKR increased their participation in physical activities in several life domains, such as occupational or social pursuits. Some patients limited their own physical activities due to uncertainty about medically appropriate levels of joint use and postoperative physical activity. Many patients noted positive effects of TKR on mood and mental health. For most patients in the study, religion offered a framework for understanding their receipt of and experience with TKR. CONCLUSION: Our findings underscore the potential of TKR to permit patients in the developing world to return to physical activities. This research also demonstrates the influence of patients' education, culture, and religion on patients' return to physical activity. As the global burden of musculoskeletal disease increases, it is important to characterize the impact of activity limitation on patients' lives in diverse settings and the potential for surgical intervention to ease the burden of chronic arthritis.

Participation in physical activity in patients 1-4 years post total joint replacement in the Dominican Republic.

BACKGROUND: To address both the growing burden of joint disease and the gaps in medical access in developing nations, medical relief organizations have begun to launch programs to perform total joint replacement (TJR) on resident populations in developing countries. One outcome of TJR of particular interest is physical activity (PA) since it is strongly linked to general health. This study evaluates the amount of postoperative participation in PA in low-income patients who received total joint replacement in the Dominican Republic and identifies preoperative predictors of postoperative PA level. METHODS: We used the Yale Physical Activity Survey (YPAS) to assess participation in postoperative PA 1-4 years following total knee or hip replacement. We compared the amount of aerobic PA reported by postoperative TJR patients with the levels of PA recommended by the CDC and WHO. We also analyzed preoperative determinants of postoperative participation in aerobic PA in bivariate and multivariate analyses. RESULTS: 64 patients out of 170 eligible subjects (52/128 TKR and 14/42 THR) who received TJR between 2009-2012 returned for an annual follow-up visit in 2013, with a mean treatment-to-follow-up time of 2.1 years. 43.3% of respondents met CDC/WHO criteria for sufficient participation in aerobic PA. Multivariate analyses including data from 56 individuals identified that patients who were both younger than 65 and at least two years postoperative had an adjusted mean activity dimensions summary index (ADSI) 22.9 points higher than patients who were 65 or older and one year postoperative. Patients who lived with friends or family had adjusted mean ADSI 17.2 points higher than patients living alone. Patients who had the most optimistic preoperative expectations of outcome had adjusted mean ADSI scores that were 19.8 points higher than those who were less optimistic. CONCLUSION: The TJR patients in the Dominican cohort participate in less PA than recommended by the CDC/WHO. Additionally, several associations were identified that potentially affect PA in this population; specifically, participants who are older than 65, recently postoperative, less optimistic about postoperative outcomes and who live alone participate in less PA.

Enhancing the quality of international orthopedic medical mission trips using the blue distinction criteria for knee and hip replacement centers.

BACKGROUND: Several organizations seek to address the growing burden of arthritis in developing countries by providing total joint replacements (TJR) to patients with advanced arthritis who otherwise would not have access to these procedures. Because these mission trips operate in resource poor environments, some of the features typically associated with high quality care may be difficult to implement. In the U.S., many hospitals that perform TJRs use the Blue Cross/Shield's Blue Distinction criteria as benchmarks of high quality care. Although these criteria were designed for use in the U.S., we applied them to Operation Walk (Op-Walk) Boston's medical mission trip to the Dominican Republic. Evaluating the program using these criteria illustrated that the program provides high quality care and, more importantly, helped the program to find areas of improvement. METHODS: We used the Blue Distinction criteria to determine if Op-Walk Boston achieves Blue Distinction. Each criterion was grouped according to the four categories included in the Blue Distinction criteria--"general and administrative", "structure", "process", or "outcomes and volume". Full points were given for criteria that the program replicates entirely and zero points were given for criteria that are not replicated entirely. Of the non-replicated criteria, Op-Walk Boston's clinical and administrative teams were asked if they compensate for failure to meet the criterion, and they were also asked to identify barriers that prevent them from meeting the criterion. RESULTS: Out of 100 possible points, the program received 71, exceeding the 60-point threshold needed to qualify as a Blue Distinction center. The program met five out of eight "required" criteria and 11 out of 19 "informational" criteria. It scored 14/27 in the "general" category, 30/36 in the "structure" category, 17/20 in the "process" category, and 10/17 in the "outcomes and volume" category. CONCLUSION: Op-Walk Boston qualified for Blue Distinction. Our analysis highlights areas of programmatic improvement and identifies targets for future quality improvement initiatives. Additionally, we note that many criteria can only be met by hospitals operating in the U.S. Future work should therefore focus on creating criteria that are applicable to TJR mission trips in the context of developing countries.

Associations between preoperative functional status and functional outcomes of total joint replacement in the Dominican Republic.

OBJECTIVE: In developed countries, the functional status scores of patients with poor preoperative scores undergoing total joint replacement (TJR) improve more following TJR than those for patients with better preoperative scores. However, those with better preoperative scores achieve the best postoperative functional outcomes. We determined whether similar associations exist in a developing country. METHODS: Dominican patients undergoing total hip or knee replacement completed WOMAC and SF-36 surveys preoperatively and at 12-month follow-up. Patients were stratified into low-, medium- and high-scoring preoperative groups based on their preoperative WOMAC function scores. We examined the associations between the baseline functional status of these groups and two outcomes-improvement in functional status over 12 months and functional status at 12 months-using analysis of variance with multivariable linear regression. RESULTS: Patients who scored the lowest preoperatively made the greatest gains in function and pain relief following their TJRs. However, there were no significant differences in pain or function at 12-month follow-up between patients who scored low and those who scored high on preoperative WOMAC and SF-36 surveys. CONCLUSION: Patients with poor preoperative functional status had greater improvement but similar 12-month functional outcomes compared with patients who had a higher level of function before surgery. These results suggest that a policy of focusing scarce resources on patients with worse functional status in developing countries may optimize improvement following TJR without threatening functional outcome. Additional research is needed to confirm these findings in other developing countries and to understand why these associations vary between patients in the Dominican Republic and patients from developed countries.
