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.

     

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.

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.     

The Impact of Healthcare Privatization on Access to Surgical Care: Cholecystectomy as a Model

Background

Privatization is widely perceived as a tool to improve healthcare access; however, its impact on the access of surgical care has not been quantified. We used cholecystectomy as a model to assess the variation in access between coexisting public (PB) and private providers (PVs).

Methods

We performed cross-sectional analysis of patients who underwent cholecystectomy at two major PB and PV groups serving Riyadh, Saudi Arabia. Representative sample sizes were estimated based on 95 % confidence level and ±5 confidence interval (CI). Exclusion criteria were major comorbidities, emergency cholecystectomies, age ≥60 and concurrent non-minor procedures. Data collected were patients’ demographics, payer status, and durations of symptoms, diagnosis and hospitalization.

Results

Between 2012 and 2104, samples of 330 and 297 were randomly selected from the total of 2164 and 1315 cases performed at PV and PB, respectively. Seventy-eight PV and 73 PB cases were excluded. The distribution of publically funded/insured/self-paid was (3/179/70 PV) and (209/0/4 PB), respectively. Median durations between symptoms and surgery for PV and PB cases were 90 and 365 days (P < 0.001), respectively, while the wait times after ultrasound-based diagnosis were 125 and 11 days (P < 0.001), respectively. Median hospitalization time was significantly shorter in PV compared to PB (1 vs. 2 days, P = 0.001), and same-day admissions were more frequent in PV 94 % than PB 41 % (RR 2.3, CI 1.9–2.7).

Conclusions

When coexist in a competitive environment, PV offers a remarkably better access to cholecystectomies compared to PB. Facilitating access to PV can be an effective strategy to improve patient’s access to surgical care.

     

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.
