Access to Orthopaedic Surgical Care in Northern Tanzania: A Modelling Study

Background

The global burden of musculoskeletal disease and resulting disability is enormous and is expected to increase over the next few decades. In the world’s poorest regions, the paucity of information defining and quantifying the current state of access to orthopaedic surgical care is a major problem in developing effective solutions. This study estimates the number of individuals in Northern Tanzania without adequate access to orthopaedic surgical services.

Methods

A chance tree was created to model the probability of access to orthopaedic surgical services in the Northern Tanzanian regions of Arusha, Kilimanjaro, Tanga, Singida, and Manyara, with respect to four dimensions: timeliness, surgical capacity, safety, and affordability. Timeliness was estimated by the proportion of people living within a 4-h driving distance from a hospital with an orthopaedic surgeon, capacity by comparing number of surgeries performed to the number of surgeries indicated, safety by applying WHO Emergency and Essential Surgical Care infrastructure and equipment checklists, and affordability by approximating the proportion of the population protected from catastrophic out-of-pocket healthcare expenditure. We accounted for uncertainty in our model with one-way and probabilistic sensitivity analyses. Data sources included the Tanzanian National Bureau of Statistics and Ministry of Finance, World Bank, World Health Organization, New Zealand Ministry of Health, Google Corporation, NASA population estimator, and 2015 hospital records from Kilimanjaro Christian Medical Center, Machame Hospital, Nkoroanga Hospital, Mt. Meru Hospital, and Arusha Lutheran Medical Center.

Results

Under the most conservative assumptions, more than 90% of the Northern Tanzanian population does not have access to orthopaedic surgical services.

Conclusion

There is a near absence of access to orthopaedic surgical care in Northern Tanzania. These findings utilize more precise country and region-specific data and are consistent with prior published global trends regarding surgical access in Sub-Saharan Africa. As the global health community must develop innovative solutions to address the rising burden of musculoskeletal disease and support the advancement of universal health coverage, increasing access to orthopaedic surgical services will play a central role in improving health care in the world’s developing regions.

     

Emergency-to-Elective Surgery Ratio: A Global Indicator of Access to Surgical Care

Background

Surgical care is essential to health systems but remains a challenge for low- and middle-income countries (LMICs). Current metrics to assess access and delivery of surgical care focus on the structural components of surgery and are not readily applicable to all settings. This study assesses a new metric for surgical care access and delivery, the ratio of emergent surgery to elective surgery (Ee ratio), which represents the number of emergency surgeries performed for every 100 elective surgeries.

Methods

A systematic search of PubMed and Medline was conducted for studies describing surgical volume and acuity published between 2006 and 2016. The relationship between Ee ratio and three national indicators (gross domestic product, per capital healthcare spending, and physician density) was analyzed using weighted Pearson correlation coefficients (r _w) and linear regression models.

Results

A total of 29 studies with 33 datasets were included for analyses. The median Ee ratio was 14.6 (IQR 5.5–62.6), with a range from 1.6 to 557.4. For countries in sub-Saharan Africa the median value was 62.6 (IQR 17.8–111.0), compared to 9.4 (IQR 3.4–13.4) for the United States and 5.5 (IQR 4.4–10.1) for European countries. In multivariable linear regression, the per capita healthcare spending was inversely associated with the Ee ratio, with a 63-point decrease in the Ee ratio for each 1 point increase in the log of the per capita healthcare spending (regression coefficient β = ?63.2; 95% CI ?119.6 to ?6.9; P = 0.036).

Conclusions

The Ee ratio appears to be a simple and valid indicator of access to available surgical care. Global health efforts may focus on investment in low-resource settings to improve access to available surgical care.

     

Out-of-Pocket and Catastrophic Expenses Incurred by Seeking Pediatric and Adult Surgical Care at a Public,Tertiary Care Centre in Uganda

Background

Surgical care is critical to establish effective healthcare systems in low- and middle-income countries, yet the unmet need for surgical conditions is as high as 65% in Ugandan children. Financial burden and geographical distance are common barriers to help-seeking in adult populations and are unmeasured in the pediatric population. We thus measured out-of-pocket (OOP) expenses and distance traveled for pediatric surgical care in a tertiary hospital in Mbarara, Uganda, as compared to adult surgical and pediatric medical patients.

Methods

Patients admitted to pediatric surgical (n?=?20), pediatric medical (n?=?18) and adult surgical (n?=?18) wards were interviewed upon discharge over a period of 3 weeks. Patient and caregiver-reported expenses incurred for the present illness included prior/future care needed, and travel distance/cost. The prevalence of catastrophic expenses (≥10% of annual income) was calculated and spending patterns compared between wards.

Results

Thirty-five percent of pediatric medical patients, 45% of pediatric surgical patients and 55% of adult surgical patients incurred catastrophic expenses. Pediatric surgical patients paid more for their current treatment (p?<??0.01)—specifically medications (p?<??0.01) and tests (p?<??0.01)—than pediatric medical patients, and comparable costs to adults. Adult patients paid more for treatment prior to the hospital (p?=?0.04) and miscellaneous expenses (e.g., food while admitted) (p?=?0.02). Patients in all wards traveled comparable distances.

Conclusions

Seeking healthcare at a publicly funded hospital is financially catastrophic for almost half of patients. Out-of-stock supplies and broken equipment make surgical care particularly vulnerable to OOP expenses because analgesics, anaesthesia and preoperative imaging are prerequisites to care.

     

Surgical Capacity Building in Uganda Through Twinning, Technology, and Training Camps

Background  

Neurosurgical capacity is extremely deficient in East African countries where 27 neurosurgeons serve more than 250 million people. To build capacity, the Duke University Medical Center and New Mulago Hospital in Uganda applied a two-pronged twinning approach that placed usable surplus equipment in a developing country’s National Hospital, combined with dedicated comprehensive surgical training camps.     

Variability in Surgical Caseload and Access to Intensive Care Services

Background: Variability in the demand for any service is a significant barrier to efficient distribution of limited resources. In health care, demand is often highly variable and access may be limited when peaks cannot be accommodated in a downsized care delivery system. Intensive care units may frequently present bottlenecks to patient flow, and saturation of these services limits a hospital's responsiveness to new emergencies.

Methods: Over a 1-yr period, information was collected prospectively on all requests for admission to the intensive care unit of a large, urban children's hospital. Data included the nature of each request, as well as each patient's final disposition. The daily variability of requests was then analyzed and related to the unit's ability to accommodate new admissions.

Results: Day-to-day demand for intensive care services was extremely variable. This variability was particularly high among patients undergoing scheduled surgical procedures, with variability of scheduled admissions exceeding that of emergencies. Peaks of demand were associated with diversion of patients both within the hospital (to off-service care sites) and to other institutions (ambulance diversions). Although emergency requests for admission outnumbered scheduled requests, diversion from the intensive care unit was better correlated with scheduled caseload (r = 0.542, P < 0.001) than with unscheduled volume (r = 0.255, P < 0.001). During the busiest periods, nearly 70% of all diversions were associated with variability in the scheduled caseload.     

The Correlation Between Poverty and Access to Essential Surgical Care in Ghana: A Geospatial Analysis

Background

Surgical disease burden falls disproportionately on individuals in low- and middle-income countries. These populations are also the least likely to have access to surgical care. Understanding the barriers to access in these populations is therefore necessary to meet the global surgical need.

Methods

Using geospatial methods, this study explores the district-level variation of two access barriers in Ghana: poverty and spatial access to care. National survey data were used to estimate the average total household expenditure (THE) in each district. Estimates of the spatial access to essential surgical care were generated from a cost-distance model based on a recent surgical capacity assessment. Correlations were analyzed using regression and displayed cartographically.

Results

Both THE and spatial access to surgical care were found to have statistically significant regional variation in Ghana (p < 0.001). An inverse relationship was identified between THE and spatial access to essential surgical care (β ?5.15 USD, p < 0.001). Poverty and poor spatial access to surgical care were found to co-localize in the northwest of the country.

Conclusions

Multiple barriers to accessing surgical care can coexist within populations. A careful understanding of all access barriers is necessary to identify and target strategies to address unmet surgical need within a given population.

     

Association of the Affordable Care Act on Access to and Outcomes After Kidney or Liver Transplant: A Transplant Registry Study

BackgroundTo evaluate the effect of the Affordable Care Act (ACA) Medicaid expansion on payor mix among patients on the kidney and liver transplant waiting list as well as waiting list and post-transplant outcomes.DesignUsing the Scientific Registry of Transplant Recipients, we performed a secondary data analysis of all patients on the kidney and liver transplant waiting list from 2007 to 2018. We described changes in payor mix by timing of state Medicaid expansion. We used competing risks models to estimate cause-specific hazard ratios for the effects of insurance and era on death/delisting and transplant. We used a Poisson regression model to estimate the effect of insurance and era on incidence rate ratio of inactivations on the waiting list. We used Cox proportional hazards models to estimate the effect of insurance and era on graft and patient survival.ResultsA decade after implementation of the ACA, the prevalence of Medicaid beneficiaries listed for transplant increased by 2.5% (from 7.4% to 9.9%) for kidney and by 2.6% (15.3% to 17.9%) for liver. Expansion states had greater increases than nonexpansion states (kidney 3.8% vs 0.6%, liver 5.3% vs ?1.8%). Among wait-listed patients, the magnitude of association of Medicaid insurance vs private insurance with transplant decreased over time for kidney candidates (era 1 subdistribution hazard ratio (SHR), 0.62 [95% CI, 0.60-0.64] vs era 3 SHR, 0.77 [95% CI, 0.74-0.70]) but increased for liver candidates (era 1 SHR, 0.85 [95% CI, 0.83-0.90] vs era 3 SHR 0.79 [95% CI, 0.77-0.82]). Medicaid-insured kidney and liver recipients had greater hazards of graft failure; this did not change over time (kidney: HR, 1.23 [95% CI, 1.06-1.44] liver: HR, 1.05 [95% CI, 0.94-1.17]).ConclusionsFor the millions of patients with chronic kidney and liver diseases, implementation of the ACA has resulted in only modest increases in access to transplant for the publicly insured vs the privately insured.     

Teaching Palliative Care and End-of-Life Issues: A Core Curriculum for Surgical Residents

Background Most surgical training programs have no curriculum to teach palliative care. Programs designed for nonsurgical specialties often do not meet the unique needs of surgeons. With 80-hour workweek limitations on in-hospital teaching, new methods are needed to efficiently teach surgical residents about these problems. Methods A pilot curriculum in palliative surgical care designed for residents was presented in three 1-hour sessions. Sessions included group discussion, role-playing exercises, and instruction in advanced clinical decision making. Residents completed pretest, posttest, and 3-month follow-up surveys designed to measure the program’s success. Results Forty-seven general surgery residents from Brown University participated. Most residents (94%) had “discussed palliative care with a patient or patient’s family” in the past. Initially, 57% of residents felt “comfortable speaking to patients and patients’ families about end-of-life issues,” whereas at posttest and at 3-month intervals, 80% and 84%, respectively, felt comfortable (P < .01). Few residents at pretest (9%) thought that they had “received adequate training in palliation during residency,” but at posttest and at 3-month follow-up, 86% and 84% of residents agreed with this statement (P < .01). All residents believed that “managing end-of-life issues is a valuable skill for surgeons.” Ninety-two percent of residents at 3-month follow-up “had been able to use the information learned in clinical practice.” Conclusions With a reasonable time commitment, surgical residents are capable of learning about palliative and end-of-life care. Surgical residents think that understanding palliative care is a useful part of their training, a sentiment that is still evident 3 months later.     

Analysis of Contemporary Trends in Access to High-Volume Ovarian Cancer Surgical Care

Background  

Positive volume-outcome relationships exist for cancers treated with technically complex surgery, including ovarian cancer. However, contemporary patterns of primary surgical care for ovarian cancer according to hospital and surgeon case volume remain poorly defined.     

Quality of Care Indicators for the Surgical Treatment of Gastric Cancer: A Systematic Review

Background

Quality assurance is increasingly acknowledged as a crucial factor for the (surgical) treatment of gastric cancer. The purpose of the current study was to define a minimum set of evidence-based quality of care indicators for the surgical treatment of locally advanced gastric cancer.

Methods

A systematic review of the literature published between January 1990 and May 2011 was performed, using search terms on gastric cancer, treatment, and quality of care. Studies were selected based on predefined selection criteria. Potential quality of care indicators were assessed based on their level of evidence and were grouped into structure, process, and outcome indicators.

Results

A total of 173 articles were included in the current study. For structural measures, evidence was found for the inverse relationship between hospital volume and postoperative mortality as well as overall survival. Regarding process measures, the most common indicators concerned surgical technique, perioperative care, and multimodality treatment. The only outcome indicator with supporting evidence was a microscopically radical resection.

Conclusions

Although specific literature on quality of care indicators for the surgical treatment of locally advanced gastric cancer is limited, several quality of care indicators could be identified. These indicators can be used in clinical audits and other quality assurance programs.     

Disparities in Access to Surgical Care within a Lower Income Country: An Alarming Inequity

Background

Surgical care is not uniformly available worldwide. Inequities in surgical care and access may also vary within countries, and the present study aimed to explore these disparities in Pakistan.

Methods

The National Health Survey of Pakistan was analyzed. The proportion of people with a history of abdominal surgery (AS) was calculated and associated factors were determined by weighted multivariate logistic regression. Factors tested were age, gender, urban/rural residence, province, literacy, community development index (CDI), and economic status (ES). The CDI was developed for each sampling unit from select household and individual data. The ES was constructed from ownership of assets.

Results

A total of 59 million adults were represented. Abdominal surgery had been performed in 3.2 % adults (95 % confidence interval [CI] = 2.67, 3.84), which corresponded to an annual rate of 85.9 abdominal surgeries per 100,000 population. Wide disparities were noted, with annual rates of AS varying from 37.8 to 215.6 per 100,000 population. Urban residents were independently twice as likely as rural populations to have had AS (95 % CI = 1.3, 2.8). Higher age (OR = 2.6; 95 % CI = 1.7, 4.0), female gender (OR = 1.5; 95 % CI = 1.1, 2.1), and higher ES (OR = 1.9; 95 % CI = 1.2, 2.9) were also independently associated with AS. In rural populations ES was the only factor associated with surgery, whereas in urban populations gender and CDI had important roles to play.

Conclusions

Access to surgical care is disparate and grossly inadequate in Pakistan. This likely contributes to significant preventable morbidity and death. Physical access to surgical facilities, especially in rural areas and for those with a low CDI, is an important concern and should be prioritized in any forthcoming national policies.
